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 This research analyzes the relationship between the economic and social dimensions that converge in the empowerment. The sample consist of sixteen businessmen and businesswomen owners of a MSMEs, of eight Mexican states, based on Gender and Development (GAD) theory. The context of the analysis is the economic crisis caused by the COVID-19 pandemic. The study involved semi-structured interviews, which were processed with Atlas Ti. The research applied an axial coding, linking the empowerment with the economic and social dimensions. It shows that the main motivation in the economic dimension of business owners is economic autonomy and the management of their time. At the beginning of the entrepreneurship, the main challenges were fear and lack of resources. Nowadays, the hardships they face are the pandemic effects, the payment of taxes, and insecurity. In the social dimension, business owners agree that family is a fundamental aspect of their life. The research concludes that social dimension divergence occurs in gender disparities like care of children and household activities done almost exclusively by women, which impacts their business activity (economic dimension). It is recommended to strengthen public policies focused on GAD and its multidimensional link to empowerment.

Resumen El objetivo de esta investigación es analizar las relaciones entre las dimensiones económicas y sociales que convergen en el empoderamiento, de una muestra de dieciséis empresarias y empresarios propietarios de una mipyme, pertenecientes a ocho entidades federativas de México, con base en la teoría del género en el desarrollo (GED). El contexto de estudio se ubica en los retos derivados de la crisis económica producida por la pandemia de COVID-19. Se realizaron entrevistas semiestructuradas, analizándose mediante Atlas Ti. Se aplicó la codificación axial, para relacionar la categoría de empoderamiento con las dimensiones económicas y sociales. Los hallazgos demostraron que en la dimensión económica la principal motivación de las y los empresarios es la autonomía económica y el manejo del tiempo propio. Los principales retos al iniciar fueron el miedo y la falta de recursos. Actualmente, los desafíos que afrontan son los efectos de la pandemia, el pago de impuestos y la inseguridad. En la dimensión social, concuerdan que la familia es un pilar fundamental. Se concluye que la divergencia de la dimensión social se presenta en las disparidades de género, en el cuidado casi exclusivo de los hijos y las actividades del hogar por parte de las mujeres, lo cual impacta en su actividad empresarial (dimensión económica). Se recomienda fortalecer la implementación de políticas públicas desde el GED y su vínculo multidimensional en el empoderamiento.

Abstract: The current study attempts to address the relationship between material waste and change orders in residential building projects implemented in the West Bank in Palestine. The main objectives include: (1) identify the main factors affecting change orders in residential projects, (2) identify the main factors affecting martial waste eon construction sites, (3) address the relationship between change orders and construction material waste, (4) develop prediction model that shows the impact of change orders on material waste. To achieve this, two methods are used: (1) questionnaire survey is conducted to identify the main factors affecting change orders and the major factors of material waste on construction sites. Fourteen (14) factors believed to affect change orders and 15 factors that might affect material waste are investigated in this study. (2) Case study is conducted to address the impact of change orders on material waste. Data collected from 40 residential building projects implemented in the West Bank in Palestine. Regression analysis is used to establish the predictive model that relates the change orders and material waste. Results indicate that the top five factors affecting change orders include: change of project scope by owner, shortage in equipment and materials, change in materials, design mistakes, and change of plans by owner. It also shows that the top five factors affecting material waste are: rework, lack of labors skills, design errors, purchasing materials not complying with specifications, and frequent design changes. The results revealed a strong relationship between number of change orders and construction material waste on site.

Resumen: El presente estudio intenta abordar la relación entre el desperdicio de materiales y las órdenes de cambio en proyectos de construcción residencial implementados en Cisjordania, Palestina. Los principales objetivos incluyen: (1) identificar los principales factores que afectan las órdenes de cambio en proyectos residenciales, (2) identificar los principales factores que afectan el desperdicio de material en los sitios de construcción, (3) abordar la relación entre las órdenes de cambio y el desperdicio de material de construcción, (4) Desarrollar un modelo de predicción que muestre el impacto de las órdenes de cambio en el desperdicio de material. Para lograr esto, se utilizan dos métodos: (1) se realiza una encuesta por cuestionario para identificar los principales factores que afectan las órdenes de cambio y los principales factores de desperdicio de material en los sitios de construcción. En este estudio se investigan catorce (14) factores que se cree que afectan las órdenes de cambio y 15 factores que podrían afectar el desperdicio de material. (2) Se realiza un estudio de caso para abordar el impacto de las órdenes de cambio en el desperdicio de material. Datos recopilados de 40 proyectos de construcción residencial implementados en Cisjordania, Palestina. El análisis de regresión se utiliza para establecer el modelo predictivo que relaciona las órdenes de cambio y el desperdicio de material. Los resultados indican que los cinco factores principales que afectan las órdenes de cambio incluyen: cambio del alcance del proyecto por parte del propietario, escasez de equipos y materiales, cambio de materiales, errores de diseño y cambio de planes por parte del propietario. También muestra que los cinco factores principales que afectan el desperdicio de material son: retrabajo, falta de habilidades laborales, errores de diseño, compra de materiales que no cumplen con las especificaciones y cambios frecuentes de diseño. Los resultados revelaron una fuerte relación entre el número de órdenes de cambio y el desperdicio de material de construcción en el sitio.

Abstract: Variation orders became one of the major issues presented in construction projects. The nature of work in the construction industry is complex and difficult. Thus, variation orders are expected to occur in every project due to its nature. The purpose of this study was to investigate the causes of variation orders in construction projects in Egypt according to the perspective of professional parties working for medium and small-sized construction companies. The main method used for data collection was a questionnaire survey with experts working in the Egyptian construction industry, where 62 participants from 18 construction companies were invited to take part in the study, and 51 of them accepted the invitation. The findings showed the top-ranked causes of variation orders according to small and medium-sized construction companies were poor communication, omissions in the design, financial limitations of the owner, additional work requested by the client, and the contractor’s desire to gain more profits. Thus, a proper understanding of the causes of the problem can help establish a suitable criterion for reducing variation orders in construction projects in Egypt. The contribution of this study lies in the fact that only a very limited number of research explored the perspective of medium and small-sized construction companies in Egypt. The study can be useful for other countries with similar working conditions and still suffering from the adverse impact of variation orders.

Resumen: Las órdenes de cambio se han convertido en uno de los principales problemas observados en los proyectos de construcción. La naturaleza del trabajo en la industria de la construcción es compleja y difícil. Por lo tanto, es de esperar que las órdenes de cambio ocurran en cada proyecto debido a su naturaleza. El propósito de este estudio fue investigar las causas de las órdenes de cambio en proyectos de construcción en Egipto considerando la perspectiva de los profesionales que trabajan para empresas constructoras de tamaño medio y pequeño. El principal método utilizado para la recolección de datos fue una encuesta de cuestionario aplicada a expertos que trabajan en la industria de la construcción egipcia. Se invitó a 62 participantes de 18 empresas constructoras a participar en el estudio, de los cuales 51 aceptaron la invitación. Los hallazgos revelaron que las principales causas de las órdenes de cambio para las empresas constructoras de tamaño mediano y pequeño fueron la comunicación deficiente, omisiones en el diseño, limitaciones financieras del propietario, trabajo adicional solicitado por el cliente y el deseo del contratista de obtener más beneficios. La comprensión adecuada de estas causas puede ser útil para establecer un criterio adecuado para reducir las órdenes de cambio en los proyectos de construcción en Egipto. Este estudio contribuye al mejorar el muy limitado número de investigaciones que han explorado la perspectiva de las empresas constructoras de tamaño mediano y pequeño en Egipto. De igual forma, puede ser útil para otros países con condiciones de trabajo similares y que aún sufren el impacto adverso de las órdenes de cambio.

ABSTRACT The case of a 10-year-old Golden Retriever dog treated at the ASMEVET veterinary hospital in the city of Tunja, Colombia is presented. The owner reported that the patient had an intermittent cough for 2 months. The physical examination revealed the patient to be hyperactive, body condition 4/5, and faint heart sounds. Echocardiography, chest xray, and electrocardiogram were performed, revealing pericardial effusion, increased size of the cardiac silhouette, and deviation of the S-T segment. Initially, treatment was attempted with antibiotics, diuretics and anti-inflammatory agents, without a favourable response. Two months later, it was necessary to perform emergency pericardiocentesis due to cardiac tamponade, and partial subphrenic pericardiectomy. Histopathological analysis revealed a paraganglioma. The patient survived 673 days after surgical treatment.

ABSTRACT Companion animals lack succession rights because in Peruvian law there is no absolute freedom to testate, so it is necessary to find the legal figure that allows their owners to have the possibility of arranging their protection when they have died. The present study aims to determine how companion animals could be protected upon the death of the owner in Peruvian law. It is found that, although there is no specific regulation, the figure of the position incorporated in a legacy within the will or in a donation could protect them.

RESUMEN Los animales de compañía carecen de derechos sucesorios debido a que en el derecho peruano no existe libertad absoluta de testar, por lo que es necesario encontrar la figura jurídica que permita a sus dueños tener la posibilidad de disponer su protección cuando ellos hayan fallecido. La presente investigación pretende determinar cómo se podría proteger a los animales de compañía a la muerte del titular en el derecho peruano. Se encuentra que, si bien se carece de una regulación específica, la figura del cargo incorporado en un legado dentro del testamento o en una donación, podrían protegerlos.

A methodology for building pragmatic physics-based models is here adapted to predict the erosion of ladle linings in the steel industry, in order to support operators when deciding whether the lining can be used safely for another heat. A defective lining may allow 140 t of molten steel to spill, with disastrous consequences for workers and plant. The adopted work flow for the development, challenges faced, and some model results are presented. One key learning outcome is that model development should allow time for maturing the process understanding, as well as for many iterations by 'questions-responses and actions' at various stages in the model development. Good interaction between the development team and industry case owner is an important success factor. Combining or extending the model with the use of machine learning and cognition-related methods, such as knowledge graphs and self-adaptive algorithms, is discussed.

Abstract 20. In Peru, cattle fasciolosis is an important problem in the livestock industry, causing economic losses, being widely distributed and whit endemic livestock areas. This study was carried out to determine the prevalence and risk factors in the Arequipa region. A total of 1,838 fecal samples were examined using the metal mesh sieving technique and the sediment was examined under a microscope. The owner was interviewed to learn about the management characteristics of his livestock. The data were analyzed by a multiple logistic regression model, ANOVA was used for the variables to show significance (p<0.05) and the Odds Ratio was calculated for the factors within the variables, with risk values greater than 1. The prevalence of bovine fasciolosis in the Arequipa region was moderate (34.65%), and the prevalence by provinces was 70.30%, 61.98%, 32.05%, 12.91%, 12.71%, and 3.57% for Caylloma, Condesuyos, Islay, Castilla, Arequipa, and Camaná, respectively. The risk factors for Fasciola hepatica infection that showed significance (p<0.05) were the age of juveniles and adults, the water consumed from the ditch/ river, the dosage every 6 and 12 months, and the locations of Machaguay, Chuquibamba, Iray, Andaray, Canocota, Chivay, Coporaque, Ichupampa, Achoma, Maca, Cabanaconde, Polobaya, San José de Uzuña, Vítor, Mollendo, Huambo, La Joya, Viraco, Piaca, and Pocsi. The results of the present study suggest the implementation of a control program through training, periodic treatment, and improvement in cattle management.

The potential benefits of implementing the Last Planner System (LPS) on mining infrastructure projects were explored through two case studies in the South African mining industry. The first part of the study involved measurement of the impact of LPS through earned value techniques on secondary project data. The second part sought to establish the lean construction success factors leading to improvements in construction performance. This was done by means of a research questionnaire distributed to the project owner's teams, contracted parties, and the LPS facilitators. The results revealed a positive correlation between LPS application and planned percentage complete. However, the performance achieved during the LPS pilot was not sustained. The success factors and benefits considered most evident in the case study pilot differed among the three stakeholder groups. The findings are expected to guide construction stakeholders to better define performance measures and focus on factors required to make LPS implementation more effective in the South African mining sector.

ABSTRACT: This study assessed the efficacy of an intra-articular injection of allogeneic adipose tissue-derived from mesenchymal stem cells (AD-MSCs) for the treatment of hip dysplasia in dogs. The study group included 12 otherwise healthy dogs of different breeds, ages, weights, and degrees of hip dysplasia diagnosed using radiography. An orthopedic assessment was performed on all dogs before and at 30, 60, and 90 days after infusion of AD-MSCs(2 × 106cells). On the same days, each dog’s owner answered a questionnaire based on theHelsinkiChronic Pain Index. The data were converted to ordinal data based on the score for each variable, and the Friedman test for multiple comparisons was used to verify the results. Compared with the corresponding values on day 0, orthopedic and gait assessments and owners’ reported pain indexes improved over the 90-day observation period. These results suggested that treatment with allogeneic AD-MSCs significantly reduced the clinical signs associated with hip dysplasia during the study period. However, long-term studies are needed to determine the optimal therapeutic protocol for routine clinical use of AD-MSCs in hip dysplasia.

RESUMO: O objetivo deste estudo foi avaliar a eficácia clínica da aplicação intra-articular de células-tronco mesenquimais alógenas derivadas do tecido adiposo (AD-CTM) no tratamento de cães portadores de osteoartrite secundária a displasia do coxofemoral (DCF). Doze cães de ambos os sexos, diferentes raças, idades e peso, portadores de graus variados de DCF comprovada em radiografia e livres de quaisquer outras alterações clínicas ou ortopédicas, foram utilizados no estudo. Todos os cães foram submetidos a avaliação ortopédica nos dias 0, 30, 60 e 90 após aplicação de AD-CTM na dose de 2 x 106. Além disso, os tutores preencheram a um questionário, baseado no Índice de dor crônica de Helsinque (IDCH) nos mesmos intervalos. Em comparação com o dia 0, observou-se melhora significativa na avalição em locomoção e físico-ortopédica assim como na avaliação dos tutores pelo IDCH ao longo dos 90 dias. Os resultados permitem inferir que as AD-CTM alógenas contribuíram significativamente para a redução dos sinais clínicos comumente associados a DCF durante o período de estudo. Entretanto, há necessidade de estudos de longo prazo para melhor determinação de protocolos terapêuticos baseados no uso de AD-CTM na rotina clínica.

Abstract Accumulation of heavy metals in soil can lead to the deterioration of soil quality, reduce soil fertility and crop yields, and thus threaten human and animal health. The study aimed to assess the potential ecological risk of heavy metal contamination of agricultural soils in Kazakhstan. The study was carried out in 2021 on the soils of the Zhdanovskoye owner-operated farm in the Sokolovsko-Sarybai district of the Kostanay region. The quantitative content of heavy metals, such as lead (Pb), mercury (Hg), arsenic (As), and cadmium (Cd), was determined, and concentrations of trace elements, such as zinc (Zn), copper (Cu), iron (Fe), and manganese (Mn), were calculated for the considered contaminated lands. The potential ecological risk index (RI) proposed by L. Hakanson was used in the study concerning heavy metal contamination of soil. As a result, the presence of trace elements and heavy metals in the considered areas of the Kostanay region was shown. The RI values for all sites ranged from 137 to 447, corresponding to the level of ecological risk grading from low to high. The average RI for As, Cd, Hg, Pb, Zn, Ni, and Cu amounted to 328, which indicates a high ecological risk. Detected levels of As, Cd, Zn, and Pb in long-term abandoned mining areas were well above national thresholds, indicating the impending need to fully investigate and assess the suitability of the land for further agricultural use. The availability of such data will allow predicting cluster-based development of processing infrastructures in the vicinity of agricultural lands. quality yields health Kazakhstan 202 owneroperated owner operated SokolovskoSarybai Sokolovsko Sarybai , (Pb) Hg (Hg) (As) Cd (Cd) determined Zn (Zn) Cu, (Cu) Fe, Fe (Fe) Mn, Mn (Mn) lands (RI L result shown 13 447 Ni 328 longterm long term thresholds use clusterbased cluster based 20 (Pb (Hg (As (Cd (Zn (Cu (Fe (Mn 1 44 32 2 4 3

Resumo A acumulação de metais pesados no solo pode levar à deterioração da qualidade do solo, reduzir a fertilidade do solo e o rendimento das colheitas, ameaçando assim a saúde humana e animal. O conteúdo quantitativo de metais pesados, como chumbo (Pb), mercúrio (Hg), arsênio (As) e cádmio (Cd), foi determinado, e as concentrações de oligoelementos, como zinco (Zn), cobre (Cu), ferro (Fe) e manganês (Mn), foram calculadas para as terras consideradas contaminadas. O índice de risco ecológico potencial (IR) proposto por L. Hakanson foi utilizado no estudo de contaminação do solo por metais pesados. Como resultado, foi demonstrada a presença de oligoelementos e metais pesados nas áreas consideradas da região de Kostanay. Os valores de IR para todos os locais variaram de 137 a 447, correspondendo ao nível de classificação de risco ecológico de baixo a alto. O IR médio para As, Cd, Hg, Pb, Zn, Ni e Cu foi de 328, o que indica um alto risco ecológico. Os níveis detectados de As, Cd, Zn e Pb em áreas mineiras abandonadas há muito tempo estavam bem acima dos limites nacionais, indicando a necessidade iminente de investigar e avaliar exaustivamente a adequação da terra para posterior utilização agrícola. A disponibilidade de tais dados permitirá prever o desenvolvimento baseado em clusters de infraestruturas de processamento nas proximidades de terras agrícolas. colheitas animal , (Pb) Hg (Hg) As (As Cd (Cd) determinado (Zn) Cu, (Cu) Fe (Fe Mn, Mn (Mn) contaminadas (IR L resultado Kostanay 13 447 328 nacionais agrícola agrícolas (Pb (Hg (Cd (Zn (Cu (Mn 1 44 32 4 3

ABSTRACT: The objective of the present study was to know the profile of Brazilian cat owners and their perceptions of responsible ownership and the veterinary care environment. The application of a semi-structured online questionnaire investigating the owner’s socioeconomic level and perception of knowledge concerning health care and history of medical-veterinary care of their cats using the snowball method. A total of 5,213 participants were included, of which: 93% were women, 52% were single and lived in urban areas (96%). Fifty nine per cent of the owners answered that their cat is taken to the veterinary care service only when it shows a clinical sign and 65% of them feel anxious when they need to take their cats to the vet. Only 1% of the owner did not consider the cat as a family member. Concerning the veterinary care scenario, 40% of the owners answered that at least once, that their cat(s) had been handled inappropriately by veterinary service professionals, and they believed that low affinity with the species and excessive restraint were the main causes for this misconduct. Around 40% of the owners had already changed their veterinarian because of this inappropriate interaction/handling. Conclusion and relevancethe data presented point to the importance of implementing and improving friendly and gentle care practices with cats and their owners.

RESUMO: O número de gatos vem crescendo nos lares brasileiros e estima-se que dentro de aproximadamente uma década ultrapasse o de cães. Esse aumento gera demanda de serviços veterinários que estejam aptos a receber apropriadamente felinos e seus donos. Os gatos são considerados animais muito reativos às adversidades, o que faz com que possam ser levados a um estado de estresse rapidamente. A má compreensão de como reagem ao medo e à dor dificulta o andamento das consultas e leva a subsequente falta de cuidados veterinários de rotina. Diante disso, o objetivo deste estudo foi conhecer o perfil de tutores, percepções sobre o comportamento felino e possíveis obstáculos enfrentados por eles no que diz respeito aos cuidados com a saúde dos pets. Os dados foram coletados a partir de questionário semiestruturado disponibilizado em plataforma online. Foram incluídos 5.213 participantes, dos quais: 93% eram mulheres, 52% eram solteiros e residiam em áreas urbanas (96%). Cinquenta e nove por cento dos proprietários responderam que seu gato só é conduzido para consulta quando apresenta algum sinal de doença e 65% deles ficam ansiosos quando precisam levar seus gatos ao veterinário. Em relação ao cenário do atendimento veterinário, 40% dos proprietários responderam que seus gatos já foram manipulados de maneira inadequada por profissionais do serviço sendo a baixa afinidade com a espécie e a contenção excessiva as principais condutas observadas. Cerca de 40% dos proprietários já trocaram de veterinário por conta dessas condutas. Os dados apresentados apontam para a importância de implementar e melhorar práticas de cuidados amigáveis e gentis com gatos e seus donos para que a saúde e bem estar desses animais sejam preservadas.

ABSTRACT: Trypanosoma evansi, the hemoflagellate pathogen that causes “surra,” is a protozoan that infects the widest variety of mammals worldwide, primarily horses, camels, dogs, and wild animals. Cases of canine trypanosomiasis caused by T.evansi have been reported in the Brazilian pantonal region. This study determined the prevalence of T.evansi and investigate risk factors. The study used blood samples from dogs in the municipality of Barão de Melgaço in the pantonal of the state of Mato Grosso, Brazil. The owner was given a structured epidemiological questionnaire containing information about the risk factors. The quantitative polymerase chain reaction technique was used to detect T.evansi DNA using species-specific oligonucleotides TevF and TevR of the gene encoding a 227-bp portion of the glycoprotein of the variant surface (VSG) T.evansi Rode Trypanozoon (RoTat) 1.2. Two (prevalence of 0.5%) genetic materials of T.evansi were reported in the403 samples. Although, no risk factor was associated with infection (P > 0.05), proximity to vegetation and streams, as well as the presence of tabanids, rodents, and marsupials, which are factors in the occurrence of infection, were observed in positive dogs, implying that the municipality of Barão de Melgaço has epidemiological characteristics that allow canine infection by T.evansi.

RESUMO: Trypanosoma evansi, o patógeno hemoflagelado que causa a “surra”, é um protozoário que infecta a mais ampla variedade de mamíferos em todo o mundo, principalmente cavalos, camelos, cães e animais selvagens. Casos de tripanossomíase canina causada por T. evansi têm sido relatados na região pantaneira brasileira. Este estudo tem como objetivo determinar a prevalência de T. evansi e investigar fatores de risco. O estudo utilizou amostras de sangue de cães do município de Barão de Melgaço, no pantanal do estado de Mato Grosso, Brasil. O proprietário recebeu um questionário epidemiológico estruturado contendo informações sobre os fatores de risco. A técnica quantitativa de reação em cadeia da polimerase foi utilizada para detectar DNA de T. evansi utilizando oligonucleotídeos específicos da espécie TevF e TevR do gene que codifica uma porção de 227 pb da glicoproteína da superfície variante (VSG) T. evansi Rode Trypanozoon (RoTat) 1.2. Dois (prevalência de 0,5%) materiais genéticos de T. evansi foram encontrados nas 403 amostras. Embora nenhum fator de risco tenha sido associado à infecção (P > 0,05), a proximidade de vegetação e riachos, bem como a presença de tabanídeos, roedores e marsupiais, fatores na ocorrência de infecção, foram observadas em cães positivos, implicando que o município de Barão de Melgaço apresenta características epidemiológicas que permitem a infecção canina por T. evansi.
