Vergel Ortega, Mawency | 2020-01-01

En las instituciones de salud se hace necesaria la gestión bajo la perspectiva de prácticas saludables, a los fines de inicidir favorablemente en la eficiencia laboral y organizacional, tomando en cuenta las cargas de trabajo y el estrés laboral al cual se ven sometidos los trabajadores hospitalarios. En estos términos, la investigación tuvo por objeto establecer un modelo estructural para determinar la relación existente entre las estrategias organizacionales y las prácticas saludables en las Instituciones Prestadoras de Salud (IPS) de la zona fronteriza colombo-venezolana. La metodología fue cuantitativa, correlacional y de análisis factorial confirmatorio, aplicada a una muestra de 50 instituciones. Las fases del análisis fueron: el trabajo de campo para identificar y describir las estrategias y prácticas saludables en las empresas objeto de estudio; la identificación de los factores asociados a través de análisis factorial exploratorio; el análisis confirmatorio y contraste de resultados con la conceptualización teórica. Los resultados señalan que las variables planeación, recurso humano y ambiente, no tiene incidencia ni asociación con la estrategia, mientras que la variable stakeholders posee una alta relación. Se concluye que los factores de primer orden del modelo estructural lo conforman variables observables con cargas factoriales estadísticamente significativas

Rojas Suárez, Jhan Piero | 2019-09-30

In this project, a descriptive research was carried out in order to analyze, evaluate and detail the behavior of buildings between 4 and 18 floors of residential use in the City of San José de Cúcuta, Colombia, at the moment they are subjected to forces produced by earthquakes. For this purpose, a sample of 40 buildings framed in the above-mentioned characteristics was used by means of the SAP 2000 software. The seismic analysis of each building was made and the displacements of these were obtained when they are submitted before an earthquake. With this information, it was possible to calculate the drifts and evaluate them based on the requirements that determine the stiffness conditions present in the buildings. Finally, a document was drawn up identifying those buildings that are susceptible to significant damage in the event of a seismic movement and recommendations, due to the fact that they represent a social risk.

Rojas Suárez, Jhan Piero | 2019-09-30

The automobile is the main means of transportation in most cities of the world, however, its excessive use has generated several environmental and social problems, one of them is the lack of control over parking on public roads, affecting vehicle traffic, disturbing the image of the city, increasing the rate of accidents and causing negative effects on the mood of drivers and pedestrians. There are different alternatives to reduce these indicators, highlighting the effectiveness of the implementation of parking meter systems, which seek to regulate parking on public roads through a fee and a time limit. This article demonstrates the design, feasibility and impact (economic, social and environmental) of an implementation of the parking meter system in the center of the city of San José de Cúcuta, Colombia, with data from the Secretariat of Transit of the metropolitan area of the city of San José de Cúcuta, Colombia and the national institute of roads, achieving a solution to the problem of traffic congestion in the city and also contributing to create citizen culture among its inhabitants.

Rojas Suárez, Jhan Piero | 2019-11-29

The need to improve people's living conditions starts from the reality of the durability of rural road constructions, which have a short useful life and have a negative impact on the inhabitants of these regions. This project aims to improve access to rural areas, rural economic development and thus improve the quality of life of people in the sector; taking into account that at the moment of building a rural road, has a better resistance and durability in time, this was done by analyzing the properties of the clay mixture of low plasticity in the dosage of soil-cement that were tested by tests to determine the liquid limit of soils, determination of the plastic limit, plasticity index, moisture test, classification of soil by sieving, granulometric analysis, unit weight-humidity relations in soils, soil support relationship in the laboratory; in order to find the best dosage that provides greater strength, long-term durability and risk reduction. The results indicate that this type of clay requires an improvement with cement, due to its bearing capacity of 2% and 4%, which gives it a very poor quality to be used in the construction of rural roads.

Rojas Suárez, Jhan Piero | 2019-09-30

An experimental investigation was made in search of the improvement of the material used for the conformation of the subgrade in pavements. Three separate excavations were carried out 150 m apart in a 510 m stretch located in the Guayabal environmental technology park in the city of San José de Cúcuta, Colombia. In each excavation 2 samples were taken at depths of 0.50 m and 1 m. The soil samples extracted were analyzed in accordance with the regulations of the "Instituto Nacional de Vías" of Colombia in its update of 2013. It was collected material, not superior to 20 mm, of biosanitary residues treated by the Ecosterile machine series 250C located in the environmental technological park Guayabal. Five experimental mixtures were carried out partially substituting 2%, 6%, 8%, 10% and 14% of the weight of the excavated soil with treated biosanitary residues, random percentages taken as initial reference in the experimentation due to the characteristics of the substitute material. The California bearing ratio test was performed on experimental mixtures whose data were tabulated and compared with those obtained in similar tests carried out on the material conventionally used for the improvement of the subgrade in pavements according to Colombian regulations. The tests provided interesting information that concluded in the substitution of 2% of the conventional material to improve the performance of the subgrade in the intervened section, a value that obtained better results in the California bearing ratio test, yielding 79.2% with respect to the result obtained by the conventional material. The exposed results are convenient for the economy of road projects due to the partial substitution of traditional material by residual material, at the same time the use of a hospital waste is implemented as construction material, bringing with it positive environmental and social benefits as far as its final disposition.

Rojas Suárez, Jhan Piero | 2020-11-04

The wave movements can be studied from autonomous work done by the student since they are processes in which he can appreciate and understand how the transmission of energy from one part to another without transfer of matter is. Problem-based learning constitutes a good alternative to study the concept of waves since it sequentially leads the student to structure the knowledge to use it in the context, to develop effective processes of reasoning, to develop self-directed learning skills and to motivate him/her to learn, together with the development of the capacity to work in a team and it favors the development of the mathematical physical thought. The research is developed from the multi-method methodological approach developing in-depth interviews to teachers and knowledge tests to students with the purpose of establishing both pre-knowledge and initial situations for structuring the pedagogical intervention and the evaluation of its results. The pedagogical intervention is structured on a quasi-experimental design in which the strategy of problem-based learning is applied to the teaching and learning of physics and is compared with the traditional methodology. The research allows us to conclude that applying the problem-based learning methodology to physics teaching, we obtain better educational yields than with traditional teaching, while it generates a greater motivation and a greater interest in learning. It also allows the student to integrate the knowledge into his or her context, visualize the usefulness of learning and apply knowledge to the solution of problems in his or her environment, in other words, it allows the student to achieve significant learning and therefore a development of mathematical physical thinking.

...
Valencia, Guillermo | 2019-10-25

This paper presents a thermo-economic analysis of a simple organic Rankine cycle (SORC) as a waste heat recovery (WHR) systems of a 2 MW stationary gas engine evaluating different working fluids. Initially, a systematic methodology was implemented to select three organic fluids according to environmental and safety criteria, as well as critical system operational conditions. Then, thermodynamic, exergy, and exergo-economic models of the system were developed under certain defined considerations, and a set of parametric studies are presented considering key variables of the system such as pump efficiency, turbine efficiency, pinch point condenser, and evaporator. The results show the influence of these variables on the combined power of the system (gas engine plus ORC), ORC exergetic efficiency, specific fuel consumption (∆BSFC), and exergo indicators such as the payback period (PBP), levelized cost of energy (LCOE), and the specific investment cost (SIC). The results revealed that heat transfer equipment had the highest exergy destruction cost rates representing 81.25% of the total system cost. On the other hand, sensitivity analyses showed that acetone presented better energetic and exergetic performance when the efficiency of the turbine, evaporator, and condenser pinch point was increased. However, toluene was the fluid with the best results when pump efficiency was increased. In terms of the cost of exergy destroyed by equipment, the results revealed that acetone was the working fluid that positively impacted cost reduction when pump efficiency was improved; and toluene, when turbine efficiency was increased. Finally, the evaporator and condenser pinch point increased all the economic indicators of the system. In this sense, the working fluid with the best performance in economic terms was acetone, when the efficiency of the turbine, pinch condenser, and pinch evaporator was enhanced

Thixotroic behaviour study of clayey soils from the lacustrine deposits of bogotá high plateau
...
Rojas Suárez, Jhan Piero | 2018-11-29

Thixotropy is a distinctively rheological (time-dependent) phenomenon, which is found in many complex materials, especially colloidal systems as fine-grained soils. Clays are materials that can recover their initial strength after remoulding. The estimation of such recovering allows optimising the designs of geotechnical structures and then reducing the construction costs. This paper presents the results of a study that evaluates the thixotropy phenomenon of clayey soils. The work methodology involved an experimental plan composed of five phases: (i) extraction of samples; (ii) physical and mechanical characterisation of the undisturbed samples; (iii) remoulding of samples after testing; (iv) storage of remoulded samples; and (v) evaluation of undrained shear strength recovering for 0, 15, 30, and 60 days after remoulding. Undisturbed samples were collected using Shelby tube from the municipality of Madrid, near Bogotá, in Colombia. Results were analysed in terms of sensitivity degree because this parameter allows estimating the shear strength recovering. Findings show that clayey soils from lacustrine deposits of Bogota high plateau do not loss completely all of their original mechanical properties after remoulding and exhibit a medium sensitive behaviour. Conclusions indicate there is a recovering of undrained shear strength along the time, in which the samples will recover their original state about one year after remoulding.
