Department of Advanced Nursing Science / MCur / This study was carried out to assess the use of protective clothing among health care workers in selected hospitals of Vhembe District in Limpopo Province, South Africa. Protective clothing is the corner stone of health care facilities and it remains the most cost effective measure which is currently available in public health intervention. Although personal protective clothing is one of the best lines of protection against hazardous exposures, many healthcare workers either shun this protective apparel or do not wear it in an appropriate manner at the appropriate time. The purpose of the study was to assess the use of protective clothing of health care workers in selected hospitals of the Vhembe District, in the Limpopo province of South Africa. The study followed a quantitative approach using a cross-sectional design. The population comprised of all health care workers in purposefully selected hospitals and the sample was 205 health care workers who were 21 years and older. A questionnaire was selfdesigned in English, translated into Tshi-Venda, Se-Sotho and Xi-Tsonga languages. Data was collected by the researcher in selected hospitals of Vhembe District. The statistical package for social sciences (SPSS version 25) was used to analyse the collected data. Validity and reliability were ensured. Permission to conduct research was obtained from the University of Venda Higher Degree Committee, Department of Health in Limpopo Province for Ethical Clearance, and the institutions where the study was conducted. The use of protective clothing among health care workers was found to be relatively low (8, 3%) probably due to unavailability of protective clothing in the hospitals, allergic reactions and ignorance. Lack of knowledge regarding the use of protective clothing could also explain the low yield of the detected cases for not using protective clothing while on duty in this study. Based on the findings, the study conclusions and recommendations were that all health care workers should follow the stipulated policy on protective clothing and periodic awareness campaigns to be held to conscientise workers on the importance of wearing personal protective clothing. / NRF

En este artículo, se realizó un análisis de infiltración de agua en la presa de tierra Coltani ubicada en el departamento de Tacna, Perú. Primero, se realizó un análisis de infiltración mediante el programa Slide el cual permite evaluar flujos de agua por medio de la hipótesis flujo permanente, de manera bidimensional y con un suelo isotrópico. Luego, se estudió la infiltración del agua subterránea de la presa Coltani tanto en su condición inicial como en su condición con muro pantalla. En esta última, se consideró como referencia el caudal de infiltración máximo permisible para proponer las alternativas en relación a su ubicación. Se consideró un diámetro de 1.5 metros y una profundidad de 30 metros con posibles ubicaciones al inicio, centro y final de la presa. Finalmente, se obtuvieron diversos resultados de caudales de salida en el primer estrato del suelo demostrando el impacto generado por las diversas ubicaciones de los pilotes secantes como muro impermeable. Se obtuvo como principal resultado, la ubicación ideal de los pilotes secantes al final de la presa Coltani con un valor de infiltración del agua subterránea de 0.00276 m3/s en el estrato inicial, verificándose en relación al caudal de infiltración máximo permisible (Qfmp). / In this article, a water seepage analysis was performed in the Coltani earth dam located in the department of Tacna, Peru. First, a seepage analysis was carried out using the Slide program, which allows to evaluate water flows through the permanent flow hypothesis, in a two-dimensional way and with an isotropic soil. Subsequently, the seepage of the underground water from the Coltani dam was studied, both in its initial condition and in its condition as a barrier wall. The maximum allowable seepage flow was considered as a reference to propose the alternatives in relation to its location. A diameter of 1.5 meters and a depth of 30 meters were considered with possible locations at the beginning, center and end of the dam. Finally, various outflow results were obtained in the first soil stratum, demonstrating the impact generated by the various locations of the secant piles as an impermeable wall. The main result was the ideal location of the secant piles at the end of the Coltani dam with a groundwater seepage value of 0.00276 m3/s in the initial stratum, verified in relation to the maximum allowable seepage flow (Qfmp). / Trabajo de investigación

Este documento tiene como objetivo brindar propuestas de mejoramiento para evitar las infiltraciones en la presa Coltani - Tacna realizando un análisis del expediente técnico de la obra, la cual está actualmente paralizada. Estas serán realizadas por medio de la implementación de un muro impermeable conformado por Pilotes Secantes la cual es una técnica utilizada en presas de tierra para afrontar esta clase de problemas de ingeniería civil. La investigación estará dividida en secciones estratégicas para el entendimiento global, manteniendo un orden de la información. Primero, se definirán conceptos generales como los tipos de presas de tierra, sus elementos principales, requerimientos técnicos, principales fallas, técnicas de mejoramiento de suelos, infiltraciones, entre otros. Posteriormente se detallarán las características generales y específicas, tanto geológicas como geotécnicas del terreno del proyecto, recopilando la información necesaria del estudio de suelos. Luego se procederá a realizar un análisis de infiltración, mediante el uso del programa SLIDE, analizando el comportamiento del flujo del agua y caudales respuesta de la presa en su condición inicial, es decir sin la implementación del muro pantalla. Una vez analizado este comportamiento, se procederá a obtener el Caudal de Infiltración Máximo Permisible, cuyo valor servirá de base para las diferentes propuestas a considerar. Las variaciones de las alternativas para el control de infiltraciones estarán en base a dos diámetros diferentes (1.3 y 1.5m) de Pilotes Secantes con 3 posibles ubicaciones distintas, respecto a la presa (inicio, centro y final), con profundidades comprendidas entre 10 – 59m. Después se analizará el proceso constructivo de la técnica, la comparación en términos económicos respecto al costo de ejecución y se presentaran los planos y esquemas de las respectivas propuestas a considerar. Finalmente se elegirá la alternativa que presente un mayor potencial en base a la constructabilidad y costo para ser implementada como solución de la infiltración del agua en la presa Coltani. / The purpose of this document is to provide improvement proposals to avoid seepage in the Coltani - Tacna dam by analyzing the technical record of the project, which is currently paralyzed. These will be carried out through the implementation of an impermeable wall made up of Secant Piles, which is a technique used in earth dams to face this kind of civil engineering problems. The research will be divided into strategic sections for global understanding, maintaining an order of information. First, general concepts such as the types of earth dams, their main elements, technical requirements, main faults, soil improvement techniques, seepage, among others, will be defined. Subsequently, the general and specific characteristics, both geological and geotechnical, of the project land will be detailed, compiling the necessary information from the soil study. Then, a seepage analysis will be carried out, using the SLIDE program, analyzing the behavior of the water flow and response flows of the dam in its initial condition, that is, without the implementation of the screen wall. Once this behavior has been analyzed, the Maximum Permissible Seepage Flow will be obtained, whose value will serve as the basis for the different proposals to be considered. The variations of the alternatives for seepage control will be based on two different diameters (1.3 and 1.5m) of Secant Piles with 3 different possible locations, according to the dam (start, center and end), with depths between 10 - 59m. Afterwards, the construction process of the technique will be analyzed, the comparison in economic terms by the execution cost and the plans and diagrams of the respective proposals to be considered will be presented. Finally, the alternative that presents the greatest potential based on constructability and cost will be chosen to be implemented as a solution for water seepage in the Coltani dam. / Tesis

El presente trabajo de investigación pretende encontrar el diseño de un concreto permeable con la mejor relación agua/cemento, para ser usado en vías peatonales y de bajo tránsito. Además, busca demostrar que su empleo en zonas lluviosas reduce el volumen pluvial y atenúa el impacto que se produce en las poblaciones urbanas, como la ciudad de Huaraz, en las que existen continuas inundaciones debidas al uso de técnicas y métodos que provocan la impermeabilización del suelo. Se ejecutaron ensayos en laboratorio sobre la base de tres muestras con relaciones agua/cemento de 0.30, 0.35 y 0.40. Luego de someterlas a pruebas de compresión simple, flexión y permeabilidad, se encontró que el diseño que cumple con las mejores características es el de relación agua/cemento 0.30. Se concluye que, para la realidad problemática descrita, el uso de un concreto permeable con dicha relación es viable en tanto este posee un coeficiente de permeabilidad k de 0.44 mm/s o 0.44 x 10-3 m/s., que se equipara a un suelo de arena limpia con mezcla de grava y se comporta como un suelo granular. Por lo tanto, contribuirá a absorber las escorrentías, incluso en zonas con una pendiente pronunciada. / The present research work aims to find the design of a permeable concrete, with the best water/cement ratio to be used in pedestrian and low-traffic pavements. In addition, it seeks to demonstrate that use in rainy areas reduces the rainfall volume and attenuate the impact that occurs in urban populations, such as the city of Huaraz, where there are continuous floods due to the use of techniques and methods that cause the waterproofing of the soil. Laboratory tests were performed on the basis of three samples with water/cement ratios of 0.30, 0.35 and 0.40. After undergoing tests of simple compression, bending and permeability, it was found that the design that meets the best characteristics is the one of water/cement ratio 0.30. It is concluded that, for the problematic reality described, the use of a permeable concrete with this relationship is feasible as it has a permeability coefficient k of 0.44 mm/s or 0.44 x 10-3 m/s, which sand equates to a clean sand soil with gravel mixture. Therefore, it will help absorb runoffs, even in areas with a steep slope. / Tesis
