RESUMO A aplicação de esgoto sanitário utilizando o gotejamento subsuperficial contribui para mitigar os problemas atuais de disponibilidade de água e produção de alimento. Objetivou-se avaliar o feijão-caupi recebendo esgoto sanitário por gotejadores operando com diferentes vazões e profundidades. Os gotejadores operaram com as vazões de 1,6 e 3,8 L h-1 e foram instalados nas profundidades de 0, 5, 10, 15, 20, 25 e 30 cm. O feijão-caupi foi cultivado em vasos de 65 L preenchidos com solo argiloso em casa de vegetação. Utilizou-se esgoto sanitário sintético e a quantidade aplicada nos vasos foi baseada no elemento limitante, que no caso foi o nitrogênio, para o cultivo do feijão-caupi. O manejo da irrigação foi realizado com sondas de TDR. Avaliou-se a germinação e as respostas fisiológicas e morfologia das raízes do feijão-caupi. A ascensão capilar, quando a água foi aplicada em profundidade, não foi suficiente para umedecer de maneira uniforme a superfície do solo. As variáveis de germinação apresentaram um decréscimo em função do aumento das profundidades de instalação dos gotejadores. A distribuição da água com o aumento da profundidade dos emissores foi responsável pelos prejuízos nas respostas fisiológicas e morfológicas das raízes feijão-caupi. As vazões dos gotejadores não afetaram a germinação do feijão-caupi. Utilizar o sistema de irrigação por gotejamento subsuperficial não foi apropriado para o feijão-caupi nas condições deste estudo. alimento Objetivouse Objetivou se feijãocaupi feijão caupi 16 1 6 1, 38 3 8 3, h1 h h- 0 5 10 15 20 2 cm vegetação Utilizouse Utilizou limitante nitrogênio feijãocaupi. caupi.

ABSTRACT The application of sanitary sewage using subsurface drip irrigation contributes to mitigating the current problems of water availability and food production. The aim in this study was to evaluate cowpea receiving sanitary sewage through drippers operating at different flow rates and depths. The drippers operated at flow rates of 1.6 and 3.8 L h-1 and were installed at depths of 0, 5, 10, 15, 20, 25, and 30 cm. Cowpea was grown in 65 L pots filled with sandy clay soil in a greenhouse. Synthetic sanitary sewage was used and the amount applied to the pots was based on the limiting element, which in this case was nitrogen, for growing cowpea. Irrigation was managed using TDR probes. Germination and the physiological responses and morphology of cowpea roots were assessed. Capillary rise, when water was applied in subsurface, was not sufficient to evenly moisten the soil surface. The germination variables decreased as a result of the increase in drip installation depths. The distribution of water as the depth of the emitters increased was responsible for the damage to the physiological and morphological responses of cowpea roots. The flow rates of the drippers did not affect the germination of cowpea. Using the subsurface drip irrigation system was not appropriate for growing cowpea under the conditions of this study. production 16 1 6 1. 38 3 8 3. h1 h h- 0 5 10 15 20 25 cm greenhouse element nitrogen probes assessed rise surface 2

ABSTRACT Introduction/framework/objectives Multiple Sclerosis has a reasonable prevalence and the diagnosis is generally made at working age, at a stage that is still demanding on a professional level, a time when there are also generally personal/family particularities that require some dedication. Furthermore, given the incidence, diversity and severity of the symptoms presented, limitations often arise that can seriously affect the ability to work or even lead to unemployment. It is then desirable that the members working in Occupational Health and Safety teams have some knowledge on the subject, in order to better guide their performance, safeguarding the interests of everyone involved. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023, in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content It is a demyelinating and autoimmune disease of the Central Nervous System; it is characterized by recurrent and intermittent episodes of inflammation, with generally progressive destruction of axonal myelin. In most cases there is a cycle of relapses and remissions and symptoms of varying intensity; the evolution is unpredictable. Causes autonomic, visual, motor and sensory symptoms; which makes independent daily living and the ability to work difficult; sometimes becoming debilitating. It is incurable and neurodegenerative. The severity varies depending on the neurological areas most affected. The function of myelin is to facilitate conduction at the level of axons; with changes in this, the electrical impulses that coordinate mental and physical functions become less effective. As myelin deteriorates, it is replaced by scars of abnormal tissue, with different consistency (stiffness, plaques), which further disrupts conduction. Injuries to the frontal and parietal lobes often result in cognitive and emotional changes; in the spinal cord, problems arise more easily in the lower limbs. Changes in the optic nerve and occipital lobe can cause visual problems. This is the neurological desease that causes most limitations in the young adult active population. Given the reasonably young age at which symptoms begin, there will be a decrease in quality of life, more significant than in other chronic diseases. Discussion and Conclusions Although the bibliography is not scarce, the emphasis in the vast majority of articles is not on Occupational Health or Safety. It would be relevant for some teams working in large companies with some prevalence, to evaluate the cases in detail, describing the main problems detected, proposed measures and their subsequent evaluation, in order to publish not only the path, but also the conclusions obtained, for greater dissemination of the subject.

RESUMO Introdução/enquadramento/objetivos A Esclerose Múltipla tem uma prevalência razoável e o diagnóstico faz-se geralmente em idade ativa, numa fase ainda exigente a nível profissional, altura essa onde geralmente também existem particularidades pessoais/familiares que necessitam de alguma dedicação. Para além disso, dada a incidência, diversidade e gravidade dos sintomas apresentados, com frequência surgem limitações que podem condicionar seriamente a capacidade de trabalho ou até levar ao desemprego. Será então desejável que os elementos a exercer em equipas de Saúde e Segurança Ocupacionais tenham alguns conhecimentos sobre o tema, de forma a melhor orientar o seu desempenho, salvaguardando os interesses de todos os envolvidos. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023, nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo É uma doença desmielinizante e auto-imune do Sistema Nervoso Central; carateriza-se por episódios recorrentes e intermitentes de inflamação, com destruição de mielina axonal, geralmente progressiva. Na maioria dos casos existe um ciclo de relapsos e remissões e sintomas de intensidade oscilante; a evolução é imprevisível. Causa sintomas autonómicos, visuais, motores e sensoriais; o que dificulta a vida quotidiana independente e o trabalho, tornando-se por vezes debilitante. É incurável e neurodegenerativa. A gravidade varia com as áreas neurológicas mais atingidas. À medida que a mielina se detiora, ela é substituída por cicatrizes de tecido anormal, com diferente consistência (rigidez, placas), o que perturba ainda mais a condução. Lesões nos lóbulos frontal e parietal geralmente resultam em alterações cognitivas e emocionais; na espinal medula, mais facilmente surgem problemas nos membros inferiores. Alterações no nervo ótico e lobo occipital podem originar alterações visuais. Trata-se da doença neurológica que mais limitações causa na população ativa jovem adulta. Dada a idade razoavelmente jovem do início de sintomas, irá ocorrer diminuição da qualidade de vida, mais significativa que noutras doenças crónicas. Discussão e Conclusões Ainda que a bibliografia não seja escassa, a enfase da grande maioria dos artigos não é dada à Saúde ou Segurança Ocupacionais. Seria relevante que algumas equipas a exercer em empresas grandes e com alguma incidência, avaliassem com detalhe os casos, descrevendo os principais problemas detetados, medidas propostas e avaliação posterior das mesmas, de forma a publicar não só o caminho, mas também as conclusões obtidas, para maior divulgação do assunto.

Resumo Este estudo buscou explorar a perspectiva dos docentes de medicina sobre a saúde mental de seus alunos. Este estudo qualitativo baseado em grupo focal faz parte de uma pesquisa longitudinal que estudou a saúde mental de estudantes brasileiros. Um grupo foi conduzido com professores empregados em uma faculdade de medicina. Os temas discutidos abrangeram o conceito de saúde mental e educação médica. Seis professores participaram de um grupo. A saúde mental dos estudantes de medicina é um construto que engloba aspectos emocionais, capacidade de resolução de problemas e múltiplas facetas do ser humano, segundo os participantes. As práticas artísticas, os momentos de socialização e de lazer foram percebidos como estimuladores da boa saúde mental dos estudantes. Exigências excessivas geram competitividade e a expectativa do professor pelo bom desempenho do aluno com base na própria experiência pode prejudicar a saúde mental do aluno. Os participantes destacaram também que é necessária uma reformulação pedagógica que faça sentido para o processo de aprendizagem do aluno para atualizar os currículos tradicionais. A saúde mental dos estudantes de medicina é influenciada pelas experiências e trocas durante o curso de medicina, principalmente entre professor e aluno, entendidas como necessárias e inerentes ao processo de tornar-se médico. Os achados deste estudo mostram a necessidade de mudanças curriculares no processo de formação médica e de atualização da formação docente para boas práticas que reforcem a boa saúde mental.

Abstract This study sought to explore the perspective of medical faculty on the mental health of their students. This qualitative study based on a focus group is part of a longitudinal research that studied the mental health of Brazilian students. One group was conducted with faculty employed at a medical school. Topics discussed covered the concept of mental health and medical education. Six professors participated in one group. The mental health of medical students is a construct that encompasses emotional aspects, ability to solve problems and multiple facets of a human being, according to the participants. Artistic practices, moments of socialization and leisure were perceived as stimulating students' good mental health. Excessive demands generate competitiveness and the teacher's expectation of the student's good performance based on their own experience can harm the student's mental health. Participants also highlighted that a pedagogical reformulation that makes sense for the student's learning process is necessary to update traditional curricula. Medical students’ mental health is influenced by experiences and exchanges during the medical school, mainly between professor and student, understood as necessary and inherent to the process of becoming physician. The findings of this study show the need for curriculum changes in the medical education process and updating teacher training for good practices that reinforce good mental health.

Abstract Purpose: To analyze the role of the community assembly as a determining instrument to exercise governance in local indigenous politics, because the various disputes between political factions erode the social fabric and increase the inequality gap. Methodological design: A qualitative, ethnographic study in the municipality of San Luis Amatlán, Oaxaca. Fifteen in-depth interviews were carried out with authorities throughout the municipality and with the adult population. The analysis was done with the analytical categories of governance in the Internal Regulatory Systems, in addition to the participants’ opinion on the performance of the municipal administrator. Results: It was found that the recovery of the municipal community assembly, as well as the assemblies in agencies and rancherías caused greater trust among the participants, together with an increase in the possibility of tracing a joint route to recover local governance through the election of the municipal council. Limitations of the study: Although the ethnographic approach sought to give voice to multiple community actors and social sectors, the research had a greater relationship with the authorities because they coexist more closely with the resource administration processes and their oversight. Findings: The community assembly is a fundamental element of the Internal Regulatory Systems which are consistent with the local customs and habits. The function of the assembly is not only to build consensus, it also acts as a means of control and administrative surveillance. Also, there is persistent conflict derived from the institutional design of indigenous municipalities, which have forms of resolution in their uses and customs such as the assembly, which is a space to address problems directly and without intermediaries.

Resumen Objetivo: Analizar el rol de la asamblea comunitaria como instrumento determinante para ejercer gobernanza en la política local indígena, ya que las diversas disputas entre facciones políticas erosionan el tejido social e incrementan la brecha de desigualdad. Diseño metodológico: Es de tipo cualitativo con una etnografía en el municipio de San Luis Amatlán, Oaxaca. Se realizaron 15 entrevistas a profundidad con autoridades en todo el municipio y con población adulta. El análisis se hizo con las categorías analíticas de gobernanza en los Sistemas Normativos Internos, además de la opinión sobre la figura de administrador municipal. Resultados: Se constató que la recuperación de la asamblea comunitaria municipal, así como las asambleas en agencias y rancherías, provocó mayor confianza entre las partes y la posibilidad de trazar una ruta conjunta para recobrar la gobernanza local a través de la elección del cabildo municipal. Limitaciones del estudio: Aunque la etnografía buscó dar voz a múltiples actores y sectores sociales comunitarios, la investigación tuvo mayor relación con las personas autoridades ya que éstas conviven con mayor cercanía con los procesos de administración de los recursos y su contraloría. Hallazgos: La asamblea comunitaria es un elemento fundamental en los Sistemas Normativos Internos, los cuales están insertos en los usos y costumbres indígenas y su función no sólo es construir consensos, sino que además actúa como medio de contraloría y vigilancia administrativa. También existe persistente conflictividad derivada del diseño institucional de los municipios indígenas, los cuales tienen formas de resolución en sus usos y costumbres como la asamblea, la cual es un espacio para abordar problemas de forma directa y sin intermediarios.

Resumen: La investigación determinó el efecto de la mediación de un videojuego educativo en el fortalecimiento de la resolución de problemas de matemáticas. El método cuantitativo con alcance descriptivo fue aplicado. La muestra fue no probabilística con 20 estudiantes de la Institución Educativa San Jorge, en la vereda Las Damas, Municipio de Purificación, Departamento de Tolima. Las variables estudiadas fueron: desempeño en resolución de problemas, mecánicas y percepción del videojuego. La encuesta inicial reflejó que un 90% no poseían habilidades matemáticas básicas y tenían una percepción negativa del área. Entonces, fue diseñada una estrategia educativa con un videojuego denominado Corredor Matemático de Pensamiento Variacional (Comapeva), en tercera persona con Unity 3D, Adobe Ilustrator y Autodesk 3d. Fue protagonizado por Comaco: joven aventurero que superó retos matemáticos. El guion narrativo combinó elementos del constructivismo, Aprendizaje Basado en Retos (ABR) y modelo instruccional ADDIE (Análisis, Diseño, Desarrollo, Implementación y Evaluación). La herramienta fue implementada con el apoyo de los docentes. Con el videojuego el 100% de los estudiantes resolvieron retos con diversas estrategias. Disminuyó un 21% el tiempo de desarrollo de los problemas, y un 33% las solicitudes de apoyo del docente. La concentración, atención, memoria, agilidad mental, interpretación y análisis fueron fortalecidas. El videojuego facilitó la construcción de conocimientos en matemáticas de forma sustancial. En consecuencia, fue innovador, motivador y permitió la trasformación de prácticas educativas según las necesidades de aprendizaje.

Abstract: The research considers the effect of the mediation of an educational video game in strengthening mathematics problem solving. The quantitative method with a descriptive scope was applied. The sample was non-probabilistic with 20 students from the San Jorge Educational Institution, in Las Damas village, Municipality of Purificación, Department of Tolima. The variables studied were problem-solving performance, game mechanics, and videogame perception. The initial survey showed that 90% of the students did not have basic mathematical skills and had a negative perception of the subject area. Therefore, an educational strategy was then designed using a video game called the Variational Thinking Mathematical Corridor (Comapeva). The game was developed in third person using Unity 3D, Adobe Illustrator, and Autodesk 3d. It starred Comaco: a young adventurer who overcame mathematical challenges. The narrative script combined elements of constructivism, Challenge-Based Learning (CBL) and instructional model ADDIE (Analysis, Design, Development, Implementation and Evaluation). The tool was implemented with the support of the teachers. With the video game, 100% of the students were able to solve challenges using various strategies. Problem development time decreased by 21%, and teacher support requests decreased by 33%. Concentration, attention, memory, mental agility, interpretation, and analysis skills were all strengthened. The video game facilitated the construction of knowledge in mathematics in a substantial way. Consequently, the video game was found to be innovative and motivating, and it allowed for the transformation of educational practices according to the students' learning needs.

Resumen: La ejecución de proyectos de construcción, a menudo presenta obstáculos y desviaciones, lo que genera incumplimientos. La necesidad de mejorar la gestión del desempeño del cronograma es crucial para el cumplimiento de las metas del proyecto. Este trabajo tuvo como objetivo identificar los factores clave del desempeño del cronograma en proyectos de construcción con el propósito de plantear estrategias de mejora. Se elaboró un cuestionario de escala con 54 factores seleccionados a partir de la literatura, el cual fue aplicado a profesionales que se desenvuelven en proyectos de construcción en el Perú. Posteriormente se aplicó el estadístico de análisis factorial a las respuestas de los encuestados en 2 conjuntos de datos: factores de éxito y fracaso. El análisis agrupó por separado en 6 factores comunes de éxito y 7 factores comunes de fracaso. Para identificar los factores clave se llevó a cabo una segunda encuesta en base a los factores comunes y se clasificó utilizando el Índice de Importancia Relativa. Los resultados revelaron cómo los 3 primeros factores de éxito clasificados a: compromiso de los involucrados del proyecto, competencia del gerente de proyecto y competencia del propietario. Los factores de fracaso encontrados fueron: conflicto entre los involucrados del proyecto, falta de conocimiento del gerente del proyecto y la incompetencia del propietario. Se plantearon estrategias de mejora, que pueden ser empleados por los involucrados, principalmente por los gerentes, pues en estos profesionales recae la toma de decisiones, por ello, es necesario invertir tiempo y experiencia para resolver los problemas del desempeño del cronograma.

Abstract: The execution of construction projects often presents obstacles and deviations, which generate non-compliance. The need to improve schedule performance management is crucial to meeting project goals. This work aimed to identify the key factors of schedule performance in construction projects with the purpose of proposing improvement strategies. A scale questionnaire was developed with 54 factors selected from the literature, which was applied to professionals who work in construction projects in Peru. Subsequently, the factor analysis statistic was applied to the responses of the participants in 2 sets of data: success and failure factors. The analysis grouped separately into 6 common success factors and 7 common failure factors. To identify the key factors, a second survey was carried out based on the common factors and classified using the Relative Importance Index. The results revealed how the top 3 success factors classified as: commitment of those involved in the project, competence of the project manager and competence of the owner. The failure factors found were: conflict between those involved in the project, lack of knowledge of the project manager and the incompetence of the owner. Improvement strategies were proposed, which can be used by those involved, mainly by managers, since decision-making falls on these professionals, therefore, it is necessary to invest time and experience to resolve schedule performance problems.

Abstract: The present study examines the teaching strategies used by physics professors while providing a guide for students through learning activities that develop thinking skills, knowledge, and attitudes to solve specialty-related problems. A didactic approach is applied to teaching competency-based general physics in engineering within a modular structure. A mixed methodology is employed, with qualitative methods for the case study interpreting professors' discourse regarding classroom pedagogical design and practice, and quantitative methods examining teaching practice and its impact on academic performance. As a result, three main categories are identified: 1) didactic strategies, 2) technological resources, 3) and learning monitoring. It is observed that the teaching model influences student dropout rates and academic success. In conclusion, there is a preference for traditional strategies over constructivist strategies, regardless of the professor's experience level.

Resumen: El presente estudio examina las estrategias de enseñanza utilizadas por los docentes de física y provee una guía al estudiante a través de actividades de aprendizaje que desarrollen habilidades de pensamiento, conocimientos y actitudes para resolver problemas de la especialidad. Se aplica un enfoque didáctico para enseñar por competencias en física general en ingeniería bajo estructura modular. Se utiliza una metodología mixta, cualitativa para el estudio de caso que interpreta el discurso de los docentes en relación con el diseño y la práctica pedagógica de aula y el cuantitativo que examina la práctica docente y su impacto en el rendimiento académico. Como resultado, se identifican tres categorías principales: 1) estrategias didácticas, 2) recursos tecnológicos, y 3) seguimiento del aprendizaje. Se observa que el modelo de enseñanza influye en la tasa de deserción y el éxito académico de los estudiantes. En conclusión, se evidencia una preferencia por estrategias tradicionales sobre las constructivistas, independientemente de la experiencia del docente.

ABSTRACT Soil salinization, a rising issue globally, is a negative effect of the ever-changing climate, which has drawn attention to, and exacerbated problems related to soil degradation and the decline in wetland rice (Oryza sativa L.) production, leading to an unstable national economy. The use of rhizosphere inhabiting microorganisms (plant growth-promoting rhizobacteria, PGPR) is a viable method for boosting agricultural production on saline soils and reduce salt stress in rice crops. The objective of this study was to support the development of rice under salt stress by using a consortium of bacterial strains. ‘Pokkali’ rice plants inoculated with single Bacillus tequilensis and B. aryabhattai isolates were compared with consortium and non-inoculated plants while salinity was increased and by irrigation with tap water (control), 30 mM (5 dS m-1) and 60 mM (10 dS m-1) NaCl. The present study exhibited that inoculation of a mixed inoculum at 5 dS m-1 resulted in significantly higher dry weight of the shoots and roots of seedlings (9.29 and 1.24 g, respectively) which was due to the increased SPAD value, proline content (7.55 µmol g-1 FW), and antioxidant enzyme activity in the inoculated plants. The higher accumulation of osmoprotectants such as proline supported Na+ ion reduction and antioxidant enzymes such as ascorbate peroxidase and reduced polyphenol oxidase content protect against higher cellular damage, eventually leading to increase plant growth performance in saline soil. This study demonstrates some positive effects of the locally isolated salt tolerant consortium PGPR strains on the growth of rice plants under salt stress conditions.

Abstract: Manufacturing companies face demand fluctuations and must deliver the required quantity of parts to their customers within the required time; however, companies face different challenges in fulfilling them. One is technological advances, which make it impossible for them to compete with other countries, such as China, due to financial issues. Therefore, manufacturing companies use continuous improvement methodologies to achieve better performance in their processes. Six Sigma and Lean Manufacturing are some of the best-known approaches. This article briefly presents the application of a lean sigma approach oriented to solving problems. This research proposes a methodology based on Lean Sigma that contrasts what different authors currently do: continuous improvement projects that take up to 12 months to produce results and do not solve a problem. This implementation is conducted in a process that manufactures metal parts and fails to deliver them on time to its customers. Using tools such as the Single Minute Exchange of Die (SMED) in a production line, on-time deliveries were increased from 89 % to 96 %; at the same time, the model change times were reduced by approximately 60 %, which is required for the implementation of this methodology for only four weeks, unlike the traditional six-sigma approach that can take up to 12 months to improve the process.

Resumen: Las empresas manufactureras presentan fluctuaciones en sus demandas y no entregan a sus clientes la cantidad de partes en el tiempo requerido. Son diferentes los retos que enfrentan estas empresas, uno de ellos son los avances tecnológicos que, por cuestiones financieras, no es posible competir con otros países, tales como China. Es por esto, que las empresas manufactureras hacen uso de metodologías de mejora continua para lograr un mayor desempeño en sus procesos. Algunos de los enfoques más conocidos son Seis Sigma y Manufactura Esbelta. En este artículo se presenta una aplicación de un enfoque Lean-Sigma, el cual se orienta a resolver problemas en un corto periodo de tiempo. El propósito de esta investigación es proponer una metodología basada en Lean-Sigma que permita contrastar lo que hacen diferentes autores en la actualidad, que básicamente son proyectos de mejora continua que tardan hasta doce meses en dar resultados y que no resuelven un problema. Esta implementación se lleva a cabo en un proceso que fabrica partes metálicas, el cual está incumpliendo con su cliente en las entregas a tiempo. Utilizando la herramienta de cambios rápidos de modelo (SMED) se lograron incrementar las entregas a tiempo de un 89 % a un 96 %. A su vez, los tiempos de cambio de modelo se reducen aproximadamente un 60 %, siendo requeridas para la implementación de esta metodología solo cuatro semanas, a diferencia del enfoque tradicional de seis sigma que puede tomar hasta doce meses para mejorar un proceso.

Hierdie sewe-jaar longitudinale opvoedingstudie evalueer drie akademiese afleweringsmodusse vir deeltydse MBA-studente in hul Bemarkingsbestuursmodule, naamlik vol kontak (20172019), vol aanlyn tydens COVID-19 se harde inperking (2020-2021 en die daaropvolgende gemengde modus (2022-2023). Die studie het ten doel om te bepaal of die afleweringsmodus studente se akademiese prestasie beduidend beïnvloed. Die eenrigting-variansie-analise (EVA) het beduidende verskille tussen die afleweringsmodusse vir individuele opdragte (normatiewe assessering) en groepgevallestudies (summatiewe assessering) geïdentifiseer. Daar was ook betekenisvolle verskille tussen die akademiese prestasie ten opsigte van die finale saamgestelde portefeulje van kennis (wat as eksamen dien). Hierdie portefeulje bestaan uit 'n prakties-toegepaste bemarkingsplan. Die post-hoc toetse het getoon dat studente aansienlik beter gevaar het tydens die gemengde afleweringsmodus in individuele opdragte, terwyl die volledige aanlyn modus laer punte vir die groepgevallestudies gehad het. Beide die gemengde en volledige kontakmodusse het beduidende opeenvolgende verbetering vir die groepgevallestudies getoon, wat in elke gevallestudie verbetering getoon het namate die semester gevorder het. Dit verskil van volledige aanlyn onderrig. Die gemengde modus het ook aansienlik beter gevaar in die eksamen- en finale modulepunte en het selfs beter gevaar as volkontakklasse.

The COVID-19 pandemic significantly transformed the tertiary education landscape. Traditional contact universities were forced abruptly to adopt a full-distance education mode, a situation neither the students nor lecturers were prepared for. Many lectures and teaching activities were developed on the fly as universities struggled to roll out the needed support in double-time for lecturers and students. This new normal for education required integrating technology, advanced communication software, revised assessment techniques, and recognising the need for flexible and adaptable approaches to teaching and learning. Students also evolved and gained technological proficiency, adaptability, time management, soft skills, social media proficiency, and an awareness of health and well-being. Albeit uncertain in redefining the new normal, universities continue to provide quality education. However, exactly how university education should be delivered to a new breed of students in a new business environment is a challenge. This is even more so in the case of executive MBA students. After the hard lockdown and restrictions were lifted on 21 September 2020, the North-West University Business School started to explore other modes of academic content delivery. Reinstating a full contact delivery mode was not an option because of remaining restrictions. High technological investment, online-educated lecturers and students, and benefits and developments during online learning now form a new normal for the Business School. Which teaching method, or rather, which mode of delivery, is the most relevant and adequate? Should the MBA lectures return to the historic full-contact delivery mode, stick with the newly established full online mode, or attempt to integrate the benefits of both into a hybrid mode of delivering business education to a new breed of technology-savvy students? This study, therefore, examines the academic performance of the different delivery modes by comparing data of Executive MBA Marketing management students at the NWU Business School in South Africa. The study examines the academic performance of these students from 2017 up to 2023. The panel database consists of Executive MBA students'marks for the module in Marketing Management from 2017 up to 2023. The database contains marks for individual assignments, groupwork case studies, final individual- and groupwork marks, exam marks and the final module mark. The final assessment is a portfolio of evidence comprising a detailed marketing plan for a product, service, or organisation of choice. The mode of delivery served as the dependent variable, while the independent variables comprised the marks for each assignment (groupwork, individual and portfolio of evidence). Three delivery modes were compared, namely full-contact (2017-2019), full-online (2020-2021), and the post-pandemic hybrid mode currently in effect (2022-2023). The data comprised 630 cases. However, the analysis of variance (ANOVA) used 532 cases to compare the different groupwork assignments (230 full-contact students, 159 full-online students, and 143 hybrid students). Cronbach's alpha coefficient measured the data's reliability, and one-way ANOVA determined significant differences (p<.05) between the academic performance of the three delivery modes. The analysis confirmed that significant differences exist between the modes of delivery for individual assignments, group case studies and exams (p<.05). The Tukey ab post-hoc tests showed that students performed significantly better during the hybrid delivery mode in individual assignments (69.2%) than full contact (63.8%). Regarding the individual assignment, the full online (63.8%) and full contact (63.7%) delivery modes perform significantly worse than the hybrid (69.2%) delivery mode. Regarding the first group case study (Group Assignment 1), full online performs (67.3%) significantly worse than hybrid (71.1%) and full contact (73.6%) delivery modes. There is no significant difference between the hybrid and full contact delivery modes. In the second, third, and fourth group case studies (Group Assignments 2, 3 & 4), the hybrid delivery mode (82.37%, 75.4%, 82.7%) outperforms the full contact (75.4, 80.1%, 86.6%) and full-online (71.4%, 71.4%, 67.8%) modes. The hybrid delivery mode, therefore, proves to be more conducive towards academic performance in group work. Finally, in considering the final module mark, the hybrid delivery mode (71.0%) is significantly higher than the other two delivery modes. However, there is no significant difference between full online (67.5%) and full-contact (67.2%) delivery modes regarding the final module mark. Nevertheless, it is noteworthy that the better performance in the final module marks is a function of the groupwork where the students analysed case studies together. There are no significant differences in the exam marks between the delivery modes, so better academic performance in the hybrid mode of delivery where groupwork is concerned culminates in the better module mark. Based on the findings, it is evident that the hybrid mode of delivery results in the best academic performance. This observation is based on three reasons, namely 1) students performed better in both the normative and summative assessments during hybrid tuition; 2) there is continuous progressive learning throughout the semester regarding the group case studies (summative assessment). They learn to improve and hone their skills to analyse better and apply business solutions to real-life problems experienced by organisations. This is based on students' improving marks in the group case studies as they become more proficient in analysing and answering the applied case studies because they learn from each case study; and 3) the students perform better academically in their normative assessments and earn higher final module marks (partially due to reason 2). It is concluded that the hybrid delivery mode facilitates the academic performance of post-pandemic executive MBA Marketing management students. JEL KODES: I23, I21, M30

Abstract The essay aims to discuss the functions of technological knowledge in social management, and the premises that justify its performance as a solution to social problems linked, specifically, to poverty. In the social field, technological knowledge has gained a recognized place of performance with respect to its technical potential for the development of solutions in the field of social assistance policy; Based on the supposed neutrality they carry, the instrumental and symbolic functions they perform constitute the bases of their legitimation as expert knowledge capable of offering “optimal” solutions. This impulse is related to local conditions of possibility, but also to the role of international organizations in the development of public policy; his statements regarding the premises that States should follow to address social problems, and the strategies to make their reform programs work. The reflection from the Uruguayan case on the trajectory of technological knowledge in the social field in the first decades of the 21st century, allows us to identify the devices and mechanisms with technological supports that define modalities and criteria for the assignment of social services, which have in turn, modeling effects on professional practices historically linked to care and the execution of social policies.

Resumen El ensayo se propone discutir las funciones de los saberes de la tecnología1 en la gestión de lo social, y las premisas que justifican su desempeño en tanto solución a los problemas sociales vinculados, específicamente, a la pobreza. En el campo social, los saberes de la tecnología han ganado un reconocido lugar de desempeño respecto a sus potencialidades técnicas para la elaboración de soluciones en el ámbito de la política socioasistencial2; a partir de la supuesta neutralidad que portan, las funciones instrumentales y simbólicas que desempeñan, constituyen las bases de su legitimación como saberes expertos capaces de ofrecer soluciones “óptimas”. Este impulso se relaciona con condiciones de posibilidades locales, pero también con el papel de los organismos internacionales en la elaboración de política pública, sus señalamien tos respecto a las premisas que los Estados deberían seguir para abordar los problemas sociales, y las estrategias para hacer funcionar sus programas de reformas. La reflexión desde el caso uruguayo sobre la trayectoria de los saberes de la tecnología en el campo social en las primeras dos décadas del siglo XXI, permite identificar los dispositivos y mecanismos con soportes tecnológicos que definen modalidades y criterios para la asignación de servicios sociales, que tienen a su vez, efectos de modelación sobre las prácticas profesionales ligadas históricamente al cuidado y la ejecución de políticas sociales.

RESUMEN El desarrollo de la autodeterminación constituye un objetivo educativo de prioridad en la formación de los educandos en situación de discapacidad intelectual pues asegura su calidad de vida. Por tanto, se requiere superar al docente en el empleo de recursos, apoyos y adaptaciones didácticas para la educación en autodeterminación. El objetivo de esta investigación consistió en diseñar una estrategia pedagógica de superación para transformar a los docentes en la dirección del proceso de enseñanza-aprendizaje, en función del desarrollo de habilidades de autodeterminación en los educandos en situación de discapacidad intelectual. Los métodos investigativos utilizados en el orden teórico y empírico fueron el análisis y síntesis, el histórico-lógico, el inductivo-deductivo y el sistémico-estructural-funcional; además de la entrevista, la observación, la encuesta, el análisis de documentos, el criterio de expertos y la triangulación múltiple, los que permitieron revelar las causales que inciden en el normal desarrollo de las habilidades de autodeterminación, así como elaborar la estrategia. Con su implementación se perfeccionó el desempeño profesional y personal de los docentes y educandos, quienes egresaron con el empoderamiento de habilidades para la toma de decisiones, la realización de elecciones, la resolución de problemas y el establecimiento de metas y objetivos.

ABSTRACT The development of self-determination constitutes a priority educational objective in the training of students with intellectual disabilities as it ensures their quality of life. Therefore, it is necessary to surpass the teacher in the use of resources, supports and didactic adaptations for education in self-determination. The objective of this research was to design a pedagogical improvement strategy to transform teachers in the direction of the teaching-learning process, based on the development of self-determination skills in students with intellectual disabilities. The investigative methods used in the theoretical and empirical order were analysis and synthesis, historical-logical, inductive-deductive and systemic-structural-functional; In addition to the interview, observation, survey, document analysis, expert judgment and multiple triangulations, which allowed us to reveal the causes that affect the normal development of self-determination skills, as well as to develop the strategy. With its implementation, the professional and personal performance of teachers and students was improved, who graduated with the empowerment of skills for making decisions, making choices, solving problems and establishing goals and objectives.

Abstract This paper aims to analyze the performance of Brazil’s Office Comptroller General (CGU) in the Bolsonaro Government concerning encouraging social accountability, as well as identifying the prospects for building democratic processes with civil society based on the new structure of the CGU, which has been changed since the beginning of the new Lula Government. In this sense, we also study three civil society organizations that have been working in partnership with the CGU, such as the Instituto de Fiscalização e Controle (IFC), the Observatório Social do Brasil (OSB), and the Amigos Associados de Ribeirão Bonito (Amarribo). Furthermore, we use a qualitative methodology based on document analysis, literature review, and interviews with CGU bureaucrats and representatives of civil society organizations. Despite the progress, there are challenges generated by structural problems, funding difficulties, and the disarticulation of network actions, which has been aggravated by the Covid-19 pandemic and the dismantling of policies generated by the previous government. However, since 2023, CGU, with a new institutional structure, has been working to get closer to civil society, looking for ways and strategies to stimulate social accountability.

Resumo Este artigo busca analisar a atuação da Controladoria Geral da União (CGU) no governo Bolsonaro, no que se refere ao incentivo à accountability social, bem como identificar as perspectivas de construção de processos democráticos com a sociedade civil a partir da nova estrutura da CGU, que está sendo alterada desde o início do governo Lula. Diante disso, são estudadas três organizações da sociedade civil que têm atuado em parceria com a CGU: o Instituto de Fiscalização e Controle (IFC), o Observatório Social do Brasil (OSB) e os Amigos Associados de Ribeirão Bonito (Amarribo). Além disso, utiliza-se metodologia qualitativa baseada em análise documental, revisão bibliográfica e entrevistas semiestruturadas realizadas com burocratas da CGU e com representantes das organizações da sociedade civil. A governança pública tem sido uma preocupação compartilhada na relação entre Estado e sociedade, em especial com a CGU se destacando na promoção do controle social. Apesar dos avanços observados, há desafios gerados por problemas estruturais, dificuldades de financiamento e desarticulação das ações em rede, o que se agravou com a pandemia de Covid-19 e o desmonte de políticas gerado pelo governo anterior. Porém, a partir de 2023, a CGU, com uma nova estrutura institucional, tem atuado no sentido de se reaproximar da sociedade civil, procurando formas e estratégias para estimular a accountability social.

Abstract The fishing industry produces byproducts that accumulate and cause environmental pollution problems; however, could be used as an alternative source of nutrients in ruminants. The objective of the present study was to evaluate the response over ruminal microbiome, apparent digestibility and productivity of Katahdin lambs fed different levels of shrimp shell meal (HCC). Four male lambs with live weight of 22 ± 2.5 kg were assigned in a repeated Latin square design (4 animals x 4 treatments). The animals were assigned for 16 days per period to diets with 0, 5, 10 and 20 g 100 g DM of HCC, the treatments were: HCC0, HCC5, HCC10 and HCC20, respectively. The greatest daily weight gain was found in the HCC5 treatment (P ≤ 0.05). However, the highest dry matter intake was observed in animals with the HCC20 diet (P ≤ 0.05). In the apparent digestibility of the dry matter there was no difference between treatments (P > 0.05), neither in the concentration of total bacteria (P > 0.05), while the concentration of cellulolytic bacteria and chitin-degrading bacteria was higher in the animals from HCC20 treatment (P ≤ 0.05). The results indicate an adaptation of the ruminal microbiome to high doses of HCC, therefore, HCC can be used in diets for sheep without effect on rumen metabolism and microbial, nutrient digestibility and animal performance.

Resumen La industria pesquera genera subproductos que al acumularse causan problemas de contaminación ambiental; sin embargo, podrían ser una fuente de nutrientes para rumiantes. El objetivo de este estudio fue evaluar la respuesta sobre el microbioma ruminal, la digestibilidad aparente y productividad de borregos Katahdin alimentados con diferentes niveles de harina de caparazón de camarón (HCC). Cuatro borregos machos con peso vivo de 22 ± 2.5 kg fueron asignados en un diseño cuadrado latino (4 animales x 4 tratamientos) repetido. Los animales fueron asignados durante 16 días por periodo a dietas con 0, 5, 10 y 20 g 100 g-1 de MS de HCC, los tratamientos fueron: HCC0, HCC5, HCC10 y HCC20, respectivamente. La mayor ganancia diaria de peso se tuvo en los animales del tratamiento HCC5 (P ≤ 0.05). Sin embargo, el mayor consumo de materia seca se observó en los animales con la dieta HCC20 (P ≤ 0.05). En la digestibilidad aparente de la materia seca no hubo diferencia entre tratamientos (P > 0.05), ni en la concentración de bacterias totales (P > 0.05), mientras que la concentración de bacterias celulolíticas y de bacterias degradadoras de quitina, fue mayor en los animales del tratamiento con HCC20 (P ≤ 0.05). Los resultados indican una adaptación del microbioma ruminal a dosis altas de HCC, por tanto, se puede usar HCC en dietas para borregos sin efecto en el metabolismo y microbiana ruminal, la digestibilidad de los nutrientes y en el desempeño de los animales.
