Este trabajo desarrolla y pone a disposición de la comunidad industrial y académica una macro en Excel capaz de convertir el plan de suministro de una familia de productos en requerimientos de recursos, mediante tres variantes del planeamiento preliminar de la capacidad: recursos globales, listas de mano de obra y perfiles de recursos. Se trata de un estudio de tipo aplicado y nivel relacional, cuyo objetivo fue utilizar los insumos de la macro y evaluar si el perfil de carga obtenido mediante las técnicas para calcular la capacidad requerida difiere significativamente en función de la holgura de los tiempos de obtención de los artículos que pertenecen a la familia. Para ello, se aplicó el test de Friedman. Los resultados confirmaron las hipótesis de investigación. Confiamos en que nuestro estudio contribuirá a una mejor comprensión de la técnica más apropiada para planifica...

The theoretical improvements on an academic issue require developing criteria useful to contrast andcompare different concepts under discussion. In the former issue of Patrimonio Cultural y Turismo (Nº 7,December 2012) we proposed a first approach to this kind of exercise concerning to “cultural routes”concept. In this article we elaborate a more detailed comparative approach, considering the same criteriaproposed to distinguish between cultural routes (or patrimonial routes if we use the terminology used in theOperational Guidelines of the World Heritage Convention) and other kind of routes which are not historic,but designed through different motivations and elements

Introduction: Having mental health is necessary for the growth and prosperity of humans and as a result of the growth of societies.Objectives: The purpose of this study was to design a mental health management model in Iran.Methods: In this exploratory study, a review study was first performed to analyze the current state of mental health services in Iran and the world. Countries were selected to compare mental health management with Iran in 6 domains. 311 faculty members with mental health were completed by completing a questionnaire with 50 items in the study. Using the factor analysis, the final model was explained. Results: The effective domains in Iranian mental health services management were named in 8 areas: Mental Health in Particular, Key Centers and Task-Shifting, Human Resources and Specialists Training, Psychological Services for Children and Adolescents, Financial Resources...

The objective of this research was to compare and test different methods and alternatives to approach factorial designs with fixed effects, when the assumptions of normality or homogeneity of variances are not met. Twenty methods investigated in the literature as an alternative to classical ANOVA (variance analysis) were described and tested, including non-parametric techniques, robust methods, permutations, methods for heterogeneous variances and transformations; which are currently available and implemented in R software. The methods were tested in a 3A2B factorial design, where factor A was varieties of pineapple (Golden, Cayenne Lisa and Hawaiian), factor B was type of crop management (conventional and organic), and the response variable was the average percentage of Brix degrees. Among the proposed methods, 15 rejected the interaction hypothesis, and when comparing the type I error ...

En la actualidad, los equipos de proyectos enfrentan un entorno laboral caracterizado por cambios tecnológicos constantes y plazos de entrega ajustados. Además, la presencia de desperdicios en la construcción es una constante. Por lo tanto, las empresas constructoras buscan eficiencia en sus proyectos, cumpliendo con plazos, costos y calidad, mientras previenen o reducen los desperdicios a través de una gestión adecuada. Sin embargo, muchas pequeñas y medianas empresas en el mercado peruano desconocen o se resisten a la adopción de nuevas metodologías colaborativas debido a la falta de información y la reticencia a invertir en actualizaciones y/o investigación. La falta de flexibilidad en los planes, la escasa colaboración entre los involucrados, la baja participación de los trabajadores en la planificación y la ausencia de indicadores centrados en los procesos son barreras ...

Objetive: The investigation consisted in investigating and validating an evaluation model of teacher's performance through the modeling of structural SEM equations applying LISREL. Method: An initial model based on the results of investigations and data from bibliographic referents was proposed. In previous studies they only consider the influence of some variables over the result variable. The proposed initial model consists of fourteen constructs. Six exogenous and six endogenous with their respective observable or measureable variables and in accordance with the causal methodology a diagram of cause is plotted — effect among the constructs, each relationship between the variables is codified for its statistical treatment. Information about the observable variables was collected through previously validated questionnaires from three sources: students, teachers and the immediate autho...

Background: In occupational health management experiential trainings for the prevention of psychosocial risks in the country are very low despite their benefits for both workers and employers. Objective: To compare over time the degree of preservation of cognitive-emotional content with the insertion of dissuasive phrases (group A) versus persuasive phrases (group B), for compliance with psychosocial health regulations in the workplace of a group of professionals from the Peruvian Amazon. Method: Quasi-experimental design of two groups pre- and post-test, the latter stage of three measurements. Thirty-two professionals (n=16 per group), ages 22 to 36 years, participated. Training lasted 18 hours spaced over six weeks (December 2018 and January 2019). Results: In group "A" after reaching 91.4% performance in post-test-1 until 90 days there was a decrease (VP: -8.1%; F2/30 = 14.69; p = .00...

In this thesis, we designed and evaluated a circuit model at the transistor level of a low-resolution and low bandwidth ADC (analog-to-digital converter) with level-crossing architecture (LCADC), used as part of the acquisition chain of a BCI (brain-to-computer interface) device. The aim is to obtain minimal specifications that could return adequate levels of accuracy at spike detection and reduce power dissipation. In addition, we included a NEO preprocessor in the test to help in the detection accuracy. To achieve the objectives proposed, we started developing a software model for the preprocessor and the ADCs to evaluate the different variations of resolution, bandwidth, noise level, and NEO window. After finding the desired minimum values, we continued with the hardware development of the ADC. We designed the level crossing architecture and a conventional SAR to have a reference agai...

Introduction: Poor knowledge on research shown by medical students, and the fact that they must complete their pre-graduate theses in a short time period, lead to doubts with respect to the quality of such research projects. Objective: To determine the quality of theses in order to obtain a medical degree in San Antonio Abad Cusco National University (from 2000 to 2009), and to establish if there is any factor influencing this. Materials and Method: This is a descriptive study using a relational model. The universe was 284 theses. The stratified and random simple included 172 theses. Data was retrospectively and cross-sectionally collected using a valid and reliable instrument, so their quality was assessed (methodology compliance and appropriateness), and we also reviewed the year theses were presented, the number of involved investigators, as well as the design and topics covered. We u...
