RESUMO A Matéria Orgânica do Solo, é um dos mais importantes indicadores da qualidade e sustentabilidade dos ecossistemas nativos e cultivados, pois influencia os atributos químicos e físicos do solo, como a capacidade de troca catiônica, a agregação, a retenção de água e o fornecimento de nutrientes para as plantas. Este estudo teve por objetivo, avaliar os atributos físicos e a distribuição do carbono orgânico nos agregados de solos sob diferentes manejos. Foram coletadas amostras de solo deformadas e indeformadas nas camadas de 0-0,1 m; 0,1-0,2 m e 0,2-0,3 m, em manejos de produção conservacionistas (sequeiro e irrigado) e manejo de produção não conservacionista (sequeiro). Avaliou-se os atributos químicos, granulométricos, a densidade do solo e os teores de carbono orgânico nos macro e microagregados para os três manejos. Para os manejos de produção conservacionistas, além dessas análises, realizou-se a determinação do diâmetro médio ponderado, do diâmetro médio geométrico, do índice de estabilidade de agregados e da porosidade total do solo. Os dados foram analisados por meio dos testes Kruskal -Wallis e teste t, devido à ausência de delineamento experimental, e por parte dos dados, não atenderem o teste de Normalidade (ShapiroWilk). A densidade e a porosidade total do solo não diferiram nos manejos conservacionistas (sequeiro e irrigado). O manejo conservacionista irrigado teve agregados com maiores diâmetros médios ponderado e geométrico, e maior índice de estabilidade de agregados. Os manejos conservacionistas (sequeiro e irrigado) tiveram maiores teores de carbono orgânico nos macros e microagregados.

ABSTRACT Soil organic matter is one of the most important indicators of the quality and sustainability of native and cultivated ecosystems, as it influences the chemical and physical properties of the soil, such as cation exchange capacity, aggregation, water retention, and supply of nutrients to plants. This study evaluated the physical properties and distribution of organic carbon in soil aggregates under different management practices. Disturbed and undisturbed soil samples were collected in the 0.0-0.1 m, 0.1-0.2 m, and 0.2-0.3 m layers under conservationist (rainfed and irrigated) and conventional (rainfed) management. The chemical properties and particle size, soil density, and organic carbon content in macro and microaggregates were assessed for the three management types. For conservationist management, in addition to these analyses, the weighted mean diameter, geometric mean diameter, aggregate stability index, and total soil porosity were determined. The data were analyzed using the Kruskal-Wallis test and the t-test, as there was no experimental design, and some of the data did not meet the normality test (Shapiro-Wilk). Soil density and total porosity did not differ for conservationist management (rainfed and irrigated). The irrigated conservationist management exhibited aggregates with larger weighted and geometric mean diameters and a higher aggregate stability index. Conservationist management (rainfed and irrigated) showed higher organic carbon contents in macro and microaggregates. ecosystems capacity aggregation retention plants practices 0.00.1 0001 0.0 0.1 0 1 0.0-0. 0.10.2 0102 0.2 2 0.1-0. 0.20.3 0203 0.3 3 0.2-0. rainfed size types analyses diameter index determined KruskalWallis Kruskal Wallis ttest, ttest t test, t-test design ShapiroWilk.

RESUMO: O advento de tratores articulados proporcionou aumento significativo da produtividade e redução dos custos das operações agrícolas. Para que o conjunto mecanizado seja eficiente é necessário que haja um entendimento do desempenho energético dos tratores nas operações. Semeadoras adubadoras operam entre 6 e 9 km/h, enquanto semeadoras permitem velocidades superiores. Aumentar a velocidade de semeadura favorece a eficiência operacional e reduz custos com mão de obra. No entanto, é importante ajustar o conjunto a fim de otimizar os parâmetros energéticos, buscando o equilíbrio entre produtividade e sustentabilidade. O objetivo deste estudo foi avaliar os parâmetros energéticos e operacionais de um trator agrícola articulado de 398kW em diferentes velocidades. O experimento foi conduzido em faixas, no delineamento de blocos casualizado. Foram empregadas cinco relações de velocidade teórica para operação de semeadura (6, 7, 8, 9 e 10 km h-1), com sete repetições, totalizando 35 unidades experimentais. Sendo mensurados os parâmetros: velocidade operacional, patinagem, rotação do motor, consumo horário e específico de combustível, eficiência térmica do motor, força e rendimento na barra de tração, consumo de combustível por área e capacidade operacional de campo. Os dados coletados foram submetidos aos testes de normalidade, quando significativos, submetidos à análise de variância. Os resultados evidenciam elevada capacidade de campo, superior a 20 ha h-1, para operação de semeadura com trator articulado, com consumo de combustível por área foi inferior 3,2 L ha-1 nas velocidades avaliadas, demonstrando vantagem em operar em maiores velocidades.

ABSTRACT: The breakthrough of articulated tractors has led to a significant increase in productivity and a cost reduction of agricultural operations. The performance of the tractor implement system depends on the understanding of the tractors’ energy parameters. Fertilizer seeders operate between 6 and 9 km h-1, while seed drills allow higher speeds. Increasing sowing speed improves operational efficiency. However, it is important to adequately set the machinery, to optimize the energy parameters, considering the balance between productivity and sustainability. This study evaluated the energy and operating parameters of a 398kW articulated agricultural tractor in a sowing operation at different speeds. The experiment was conducted in a complete randomized block design. Five theoretical speeds were chosen for the sowing operation (6, 7, 8, 9 and 10 km h-1), with seven replications (35 units). The tractor operating parameters were measured: operational speed, slippage, engine speed, hourly fuel consumption, engine thermal efficiency, specific fuel consumption, drawbar force, drawbar efficiency, fuel consumption per area and field operating capacity. The data were subjected to normality test, when significant, variance analysis. Results showed high field capacity in the highest speed and low fuel consumption per area at the highest speed.

ABSTRACT The application of wood ash in agriculture emerges as a promising technique to enhance agricultural productivity. Its chemical composition can improve soil attributes, acting as a fertilizer, corrective agent, and assisting in water retention. However, studies recommend controlled adoption to avoid adverse impacts. The objective of this article is to evaluate the potential of wood ash as a fertilization strategy in peanut cultivation, with an emphasis on optimizing plant productivity and reducing water deficit. The experiment was carried out in a greenhouse in 5 dm3 pots; the experimental design applied was randomized blocks, forming a 5x5 factorial scheme, corresponding to five doses of wood ash (0; 8; 16; 24 and 32 g dm-3) and five levels of water availability (25; 50; 75; 100 and 125% of field capacity), with four repetitions. The cultivar used was IAC OL-3. The data were subjected to the normality test to check whether they followed the normal distribution and, subsequently, subjected to analysis of variance and, when significant, subjected to regression analysis, at a 5% probability of error. Wood ash, rich in nutrients, proved to be a viable alternative source of nutrients. Doses between 18.4 and 22.8 g dm-3 of wood ash led to the most satisfactory results. The water availability that responded best ranged from 96 to 111.3%. Wood ash, at doses of 22.8 and 19.64 g dm-3, contributed to water consumption and soil water efficiency. attributes fertilizer agent retention However impacts cultivation deficit dm pots blocks x 5x scheme 0 (0 8 16 2 3 25 (25 50 75 10 125 capacity, capacity , capacity) repetitions OL3.

ABSTRACT Objective: To determine the correlation between the organizational climate, job satisfaction and burnout in the administrative staff of the Daniel Alcides Carrión National University. Methodology: The research was designed as a quantitative study applied with a correlational approach. A cross-sectional non-experimental design was used, since the measurements of the variables were made at a single time. The study population corresponded to a total of430 employees of the Daniel Alcides Carrión National University, which is why a simple random sampling was applied, with a confidence level of 95 % and a margin of error of 5 %, which allowed to determine a sample of 157 employees. For data collection, the survey technique was applied, therefore, three questionnaires were designed as instruments, one for each variable, with a Likert-type response scale. In the case of the Organizational Climate variable, this was based on three dimensions, namely: a) Recognition, b) Teamwork and c) Innovation, which helped to configure a total of 15 items to be evaluated. For the Job Satisfaction variable, it was based on three dimensions, which were: a) Job satisfaction, b) Satisfaction with remuneration and c) Satisfaction with the physical environment, constituting in turn 15 items to be evaluated, while for the Burnout variable, three dimensions were considered: a) Personal exhaustion, b) Depersonalization and c) Demotivation, for a total of 15 items to be evaluated. The questionnaires were subjected to a validity process according to the opinion of experts, who considered that they were suitable in their construction for application, in addition a pilot test was applied with a sample of 85participants, who were not part of the one included in the study, which allowed to determine that these instruments had an internal consistency of Cronbachs Alpha of0.97, 0.95 and 0.89 for the organizational climate, job satisfaction and burnout variables respectively. The data were systematized in an Excel spreadsheet to perform the descriptive statistical analysis, using measures of central tendency to check the frequency and behavior of the variables. Then, the SPSS version 22 program was used to perform inferential statistical calculations. the distribution of the normality of the data was statistically verified using the Kolmogorov-Smirnov test, since the number of the sample was greater than fifty. For the determination of the correlation between the variables, the Spearman rank correlation coefficient was used, because the sample presented a non-normal distribution. The significance of the correlation was established by a level of p<0.05 for hypothesis testing. Results: The results showed that between the Organizational climate variable and the Recognition dimension there is an average level of satisfaction (61.14 %), 35.67 % showed a high level of satisfaction and 3.19 % a very high level of satisfaction. Between the Organizational climate and the Teamwork dimension, a result of 2.23 was obtained, which indicates a perception that there is good teamwork. Regarding the Organizational climate and Innovation, it was found that 52.23 % of employees almost alwaysfeel stimulated to innovate, 33.12 % always feel motivated to innovate and 14.6 5 % sometimes feel that motivation. With respect to the variable Job Satisfaction and the dimension satisfaction with work, it was obtained that 60.5 % feel indifferent with respect to job satisfaction and 39.5 % are satisfied. For the Satisfaction with Remuneration dimension, 36.4 % of employees feel indifferent about their remuneration, 39.8 % feel satisfied and 13.1 % feel very satisfied with their remuneration. Regarding the dimension Satisfaction with the physical environment, 38.8 % declared themselves indifferent with respect to this dimension, 23.2 %o feel satisfied and 0.8 % of the samplefeel very satisfied with the physical environment. With respect to the Burnout variable and the Personal exhaustion dimension, 47.13 % of the employees presented a high level of personal burnout, 33.12 % revealed to have an average level of burnout and 19.75% showed a very high level of burnout. As for the aspect of Depersonalization, the results showed that the majority represented by 85.35% has a very high level of depersonalization, only 0.64 % presented a high level of depersonalization and 14.01 % presented an average level of depersonalization. As for the Demotivation dimension, it was obtained that 30.57 % of employees showed an average level of demotivation, while 69.43 % of workers showed a high level. Finally, the results revealed a positive and significant correlation (Spearman's Rho = 0.299) between organizational climate and job satisfaction. Likewise, a weak negative correlation (-0.153) was observed between organizational climate and burnout. In relation to the organizational climate and burnout variables, a weak negative correlation was observed with a coefficient of-0.153. While for the variables job satisfaction and burnout, a correlation coefficient of-0.024 was observed very close to zero. Conclusion: There is a positive and significant correlation between organizational climate and job satisfaction, and a negative and significant correlation between organizational climate and burnout, suggesting that a better organizational climate is associated with higher satisfaction and lower burnout in workers. This relationship highlights the importance of promoting a positive and conducive work environment to improve the job satisfaction of administrative staff. The need to focus on recognition as an essential component to promote greater job satisfaction is highlighted, it is also observed that teamwork and innovation are key aspects that contribute to the favorable organizational climate at the university. These conclusions emphasize the importance of implementing policies and practices that promote recognition, teamwork and the promotion of innovation as strategies to improve job satisfaction and prevent burnout in administrative staff. It is also highlighted that at higher levels of organizational climate, lower levels of administrative staff are observed, which is why it is important to create a healthy work environment and support the emotional well-being of employees to prevent job burnout. Ultimately, the relationship between organizational climate, job satisfaction and burnout are a multidimensional dynamic that requires a holistic approach. By continuing to research and apply effective approaches to improving the work climate, organizations can cultivate an environment where employees feel valued, motivated, and able to contribute meaningfully. Doingso will not only benefit the workers and the organization, but also set a higher standardfor well-being in the overall work environment.

ABSTRACT Objective: This paper aims at comparing the effect of using traditional and virtual teaching-learning variants on learning outcomes at the National University of Santa, Peru. Methodology: This is a quantitative, descriptive-inferential study. A hypothesis test was used to compare the teaching results between the traditional face-to-face modality and the one developed in virtual environments. These teaching results were previously defined as the average value of the grades achieved by the students, taking into account all the subjects selected under certain inclusion criteria. Results: The Kolmogorov-Smirnov normality test showed that the data on the average grades of the subjects mostly do not follow a normal distribution, while the Mann-Whitney U test, for two independent samples, showed that in 57% of the sampled subjects there were no significant differences between the teaching results of both modalities and in 43% of these subjects the results were superior with the use of the Moodle platform of the University Virtual Campus. Conclusions: According to the sample of students and subjects selected from the Professional School of Systems and Informatics, the teaching-learning modality using a virtual environment, imposed with the arrival of the pandemic, did not affect the teaching results and in some of the subjects the results were more favorable. This research can be applied in equal or equivalent conditions for the comparison of both teaching-learning modalities.

Abstract: Introduction: In general, the glass ionomer suffers effects in the clinical area, such as its solubility in the saliva itself found in the oral cavity. This solubility influences the loss of marginal integration, surface properties and aesthetics, which implies a failure of the restorative treatment. Objective: The purpose of this research was to compare the solubility of two glass ionomers, one conventional (3M ESPE Ketac Molar Easymix®) and another modified with resin (GC Gold Label 2), immersed in artificial saliva for a period of 21 days. Method: An in vitro experimental study was conducted, where fifteen tablets of conventional 3M ESPE Ketac Molar Easymix® glass ionomer and fifteen of modified glass ionomer with GC Gold Label 2 resin were prepared. This was divided into three tablets of each ionomer, with which resulted in five groups of three tablets per ionomer. In addition, a calibration was conducted so as not to affect the exclusive weight of the group of three pills, and then a weight measurement was conducted with an analytical balance for each group of pills. After that, each group of three pills was immersed in artificial saliva from the KIN Hidrat brand for 21 days to return after careful drying, evaluating the weight loss of each group by immersion in artificial saliva in percentage. Results: Statistical analysis was performed using Microsoft Excel. A database was created, and the Shapiro-Wilk normality test was applied, which showed that both groups had a normal distribution and homogeneous samples. The percentage of weight difference due to submersion in artificial saliva had an average of 3.18% for Ketac Molar Easymix ® and 4.012% for GC Gold Label 2. The student t test for independent samples was also applied to compare the difference groups. weight in percentage. Although the level of significance is 0.55, indicating that there is no statistically significant difference in the group means of the two types of ionomers, it is highlighted that, from a clinical and practical perspective, each sample represents that three ionomer tablets of glass of this brand and bottle have gained weight significantly. This suggests that there may be clinical relevance to the application of ionomers. Conclusion: The in vitro study concludes that the GC Gold Label 2 glass ionomer is the one that obtains the highest solubility, represented as a percentage, after 21 days of immersion in artificial saliva. The study found that both glass ionomers show significant weight gain after submersion in artificial saliva. Furthermore, although the statistical analysis does not show a significant difference between the two groups, the results may have important practical implications in the application of these materials in clinical use.

Resumen Introducción: En general el ionómero de vidrio sufre afectaciones en el área clínica, como la solubilidad a la propia saliva que se encuentra en la cavidad oral. Esta solubilidad influye en la pérdida de integración marginal, propiedades de superficie y estética lo que implica un fracaso del tratamiento restaurativo. Objetivo: Esta investigación tuvo como propósito comparar la solubilidad de dos ionómeros de vidrio, uno convencional (3M ESPE Ketac Molar Easymix®) y otro modificado con resina (GC Gold Label 2), sumergidos en saliva artificial por un lapso de 21 días. Método: Se realizó un estudio experimental in vitro, donde se elaboraron 15 pastillas de ionómero de vidrio convencional 3M ESPE Ketac Molar Easymix® y 15 de ionómero de vidrio modificado con resina GC Gold Label 2. Esto, se dividió en 3 pastillas de cada ionómero, con lo que se obtuvieron 5 grupos de 3 pastillas por ionómero. Además, se llevó a cabo un tarado para no afectar el peso exclusivo del grupo de 3 pastillas, para luego realizarse una medición de peso con una balanza analítica a cada grupo de pastillas. Después de eso, cada grupo de 3 pastillas fue sumergido en saliva artificial de la marca KIN Hidrat durante 21 días para volver a después de su cuidadoso secado, evaluando la pérdida de peso de cada grupo por sumersión en saliva artificial en porcentaje. Resultados: El análisis estadístico se realizó mediante Microsoft Excel. Se creó una base de datos y se aplicó la prueba de normalidad de Shapiro-Wilk, que mostró que ambos grupos tenían una distribución normal y muestras homogéneas. El porcentaje de diferencia de peso por la sumersión en saliva artificial tuvo una media del 3.18% para Ketac Molar Easymix ® y del 4.012% para GC Gold Label 2. También se aplicó la prueba t de student para muestras independientes para comparar los grupos de diferencia de peso en porcentaje. Aunque el nivel de significancia es de 0.55, indicando que no hay una diferencia estadísticamente significativa en las medias de los grupos de los dos tipos de ionómeros, se resalta que, desde una perspectiva clínica y práctica, cada muestra representa que tres pastillas de ionómero de vidrio de esta marca y frasco han ganado peso de manera significativa. Esto sugiere que puede haber una relevancia clínica en la aplicación de los ionómeros. Conclusión: El estudio in vitro concluye que el ionómero de vidrio GC Gold Label 2 es el que obtiene mayor solubilidad, representada en porcentaje, después de los 21 días de sumersión en saliva artificial. El estudio encontró que ambos ionómeros de vidrio muestran ganancia de peso significativa luego de la sumersión en saliva artificial. Además, aunque el análisis estadístico no muestra una diferencia significativa entre los dos grupos, los resultados pueden tener implicaciones prácticas importantes en la aplicación de estos materiales en el uso clínico.

ABSTRACT The nose is the central part of the face, it is important that it is in balance with the other facial elements such as lips and chin, since they provide facial esthetics to each individual. It was evaluated nasal projection in adult individuals with different facial patterns in Cuenca-Ecuador. It was a descriptive cross-sectional study, it was carried out nasal and cephalometric tracings were made in the digital program AutoCAD in 140 cephalometric radiographs in digital format of individuals between 18 and 45 years old. According to the facial type, four groups were formed: low, medium-low, medium-high and high The normal distribution of the data was evaluated, and the association was established using the Kruskal-Wallis test or one-way ANOVA depending on the normality of the data, and the post hoc Tukey test. Values below p<0.05 were considered statistically significant. Significant differences were found in the convexity of the lower dorsum, columella convexity, and soft tissue facial convexity. In the mid-high and high facial pattern, a difference in lower dorsum convexity was determined when compared between groups. Elongated faces presented a convex profile, greater convexity of the lower dorsum, and smaller columella dimension, while short faces showed a concave profile, lesser convexity of the lower dorsum, and larger columella.

RESUMEN La nariz al constituir la parte central del rostro es importante que se encuentre en equilibrio con los demás elementos faciales como labios y mentón, ya que proporcionan la estética facial a cada individuo. Se evaluó la proyección nasal en individuos adultos con diferente patrón facial en Cuenca-Ecuador. Fue un estudio descriptivo de cohorte transversal, se efectuó trazos nasales y cefalométricos en el programa digital AutoCAD en 140 telerradiografías cefálica laterales del cráneo en formato digital en individuos entre 18 y 45 años. Según el tipo facial se conformaron cuatro grupos: bajo, medio bajo, medio alto y alto. Se evaluó la distribución normal de los datos y la asociación se estableció con la prueba Kruskal-Wallis o ANOVA de un factor según la normalidad de los datos y la prueba post Hoc-Tukey. Los valores inferiores a p˂0,05 se consideró estadísticamente significativo. Diferencias significativas existió en la convexidad del dorso inferior, convexidad de la columela y convexidad facial de tejidos blandos. En el patrón facial medio alto y alto se determinó diferencia en la convexidad del dorso inferior cuando se comparó entre grupos. Las caras alargadas presentaron un perfil convexo, mayor convexidad de la parte inferior del dorso nasal y menor dimensión de la columela y rostros cortos mostró un perfil cóncavo, menor convexidad del dorso nasal y mayor columela.

RESUMEN Objetivo: Evaluar el grado de correlación entre el recuento de eosinófilos y las aminotransferasas en pacientes diabéticos y no diabéticos de un policlínico del distrito de Villa El Salvador. Materiales y métodos: Estudio observacional, analítico y correlacional que evaluó a 767 personas, de las cuales 500 fueron pacientes no diabéticos y 267 diagnosticados con diabetes mellitus en tratamiento, con tiempo de enfermedad igual o mayor a seis meses. Las variables fueron edad, sexo, glucemia basal, recuento de eosinófilos, niveles de aspartato aminotransferasa y niveles de alanina aminotransferasa. Se realizó la prueba de normalidad de Kolmogorv-Smirnov y la prueba de correlación de Spearman. Se consideró como punto de corte en decisión de significancia estadística el valor alfa igual a 0,05. Se utilizó el software Statistical Package for Social Sciences 25 para Windows. Resultados: Un 46,40 % de pacientes no diabéticos tuvieron niveles elevados de aspartato aminotransferasa y 27,20 %, niveles elevados de alanina aminotransferasa. Por otro lado, un 62,50 % de pacientes diabéticos tuvieron niveles elevados de aspartato aminotransferasa y 35,50 %, niveles elevados de alanina aminotransferasa. Se encontró que, en pacientes diabéticos, el recuento diferencial de eosinófilos se correlaciona de forma moderada y negativa con los niveles de aspartato aminotransferasa (Rho = -0,665) y con alanina aminotransferasa (Rho = -0,586), mientras que en el grupo de pacientes no diabéticos la correlación fue pobre o nula. Conclusiones: El recuento de eosinófilos se correlaciona moderada y negativamente con las aminotransferasas en pacientes diabéticos. Debido a las limitaciones del estudio y a la ausencia de antecedentes directos relacionados con esta investigación, es necesario realizar nuevas investigaciones en poblaciones más numerosas. Es posible que la interacción entre las células polimorfonucleares como los eosinófilos y los marcadores de inflamación hepática y sistémica como las aminotransferasas sea parte de los cambios fisiopatológicos tempranos de la diabetes mellitus, años o décadas antes del desarrollo de las complicaciones sistémicas micro y macrovasculares de esta endocrinopatía.

ABSTRACT Objective: To determine the correlation between eosinophil count and aminotransferase levels among patients with and without diabetes from a polyclinic in the district of Villa El Salvador. Materials and methods: An observational, analytical and correlational study was conducted with 767 individuals, out of which 500 were patients without diabetes and 267 were patients diagnosed with diabetes mellitus for at least six months and undergoing treatment. The study variables included age, sex, basal glycemia, eosinophil count, aspartate aminotransferase (AST) levels and alanine aminotransferase (ALT) levels. The Kolmogorov-Smirnov test was used to assess normality and Spearman’s correlation coefficient was applied. The cut-off point for statistical significance was set at α = 0.05. Data analysis was performed using IBM Statistical Package for Social Sciences Statistics 25.0 software for Windows. Results: Among patients without diabetes, elevated AST and ALT levels were observed in 46.40 % and 27.20 %, respectively. In contrast, 62.50 % of patients with diabetes had elevated AST levels, while 35.50 % had elevated ALT levels. Among patients with diabetes, a moderate and negative correlation between eosinophil differential count and AST (Rho = -0.665) and ALT (Rho = -0.586) levels was found, whereas the group of patients without diabetes showed a weak or null correlation. Conclusions: Eosinophil count is moderately and negatively correlated with aminotransferase levels among patients with diabetes. Given the study limitations and the lack of direct precedents, further research with larger populations are needed. The interaction between polymorphonuclear cells, such as eosinophils, and hepatic and systemic inflammatory markers, such as aminotransferases, may serve as an early pathophysiological indicator of diabetes mellitus, potentially years or decades before the onset of microand macrovascular systemic complications of this endocrinopathy.
