Impacto Del Factor Iluminación Y Psicosocial En El Desempeño Laboral Del Personal De Apoyo Y Asistencia A La Educación. Caso: UPIICSA

The adaptation of the work environment in organizations and companies, constitute the essential measures for the prevention of health risks of workers, and is carried out through adjustments and ergonomic studies. It seeks to identify the problems of workers related to their environment, work area, and occupational diseases. Visual problems, headaches, and fatigue are not unrelated to this study and can be derived from poor lighting in the work areas. This research provides the necessary information for the management of physical risks associated with lighting. This, however, ranges from detection and evaluation to some control strategies. The study was carried out within a college campus of the National Polytechnic Institute, in Mexico, which is not excluded from the impact of ergonomic factors. The most wellknown reaction to an inadequate psychosocial situation is stress. Currently, there are various approaches and theoretical models that have studied it. However, all of them have a common element: the relationship between work and the person. Health problems arise when the demands of work are not adapted to the needs, expectations or abilities of the worker or when he or she does not receive adequate compensation, or adequate attention on behalf of their superiors. Another psychosocial risk recognized in the practice of the management of psychosocial risks (without prejudice to its possible typecasting in other preventive disciplines such as ergonomics or safety) is the fatigue of the worker linked to the organization of working time, either due to excess of work time or a lack of rest. It is most commonly manifested in the forms of night work or shifts and in situations of repeated extensions of the workday or lack of proper rest between days. Whatever the case may be, these psychosocial risks usually manifest themselves in an interrelated manner. Stress is a factor that causes violence and vice versa, while fatigue is often accompanied by stressful situations, especially when it results from an excessive workload, monotonous or repetitive work, and lack of rest. Information was obtained regarding the psychosocial factors that are affecting some workers and which have a significant impact on their productivity, their well-being, and their emotional stability. It takes into account stress, economic factors, and internal factors among their co-workers. Ergonomics and productivity are defined so as to carry out the relationship between them, and in order to know the impacts it may have on the worker and on their workspace in the form of discomfort and inconveniences. Methodologically, a questionnaire was administered to a representative sample of workers and the information obtained was subsequently captured in the Statistical Package for Social Science (SPSS) program. The results and graphs were obtained to carry out the interpretation of the results and develop intervention strategies when required. The sum of the physical factor, illumination, and the psychosocial factor show that some of the workers are not comfortable in their job post, resulting to their low productivity

El Método LEST, Su Aplicación Y Evaluación En Las Prácticas Ergonómicas

There exist many paths so as to carry out ergonomic modifications. Manuals, models and methodologies can be used in order to appropriately handle loads, the design of job positions, continuous physical movements, service areas; as well as the use of techniques for team work cooperation, among others. The subject-study company is a producer of rubber-metal parts for the automobile industry. It basically depends on the operational work of its employees. This makes it absolutely important to pay attention to the manner in which they perform their activities. Many companies pay great importance to the production system without keeping in mind the real needs of workers as they are doing their work. The subject-study company is in this very situation. This paper shows and approach to ergonomics applied to the Mexican industry. In Mexico, there is little evidence of the use of the LEST method. This is an attempt to take the first steps to carry out ergonomic evaluation with the intention of knowing the conditions under which employees are working within companies and organizations in order to provide them with better working conditions. The main aim of this research is to now the most incidental variables in the workplace that have an impact on the performance of employees so as to assess the impact of such incidences through the LEST method. Data was collected from 70 workers taking into consideration their surroundings, workload, mental strains, psycho-social aspects, work shifts, and a new variable that is not considered in the method proposed by the Polytechnic University of Valencia, or by the original method. The workers were asked in a section of the questionnaire: “What would you change about your working environment to improve it?” Through observation, we were able to clearly appreciate the physical movements performed by workers as they went along their physical activities at work while registering each and every one of them. Some of the workers were even filmed to observe the repeated movements they performed during their duties. This allowed us to carry out a more in-depth analysis of such movements. The Statistical Package for the Social Sciences (SPSS) tool was used so as to tabulate all of the input collected through the questionnaires answered by the employees. By doing so, it was possible to know the frequency at which the abovementioned incidences occurred, and so an interpretation of the data was carried out. Finally, the results or conclusions obtained through this study revealed that the company has major ergonomic differences between the workload and the work environment, specifically the thermal environment, the acoustic environment and the lighting in the workplace. These areas are closely connected with productivity. In general, the company must modify several aspects in the workplace such as their high staff turnover, as well as the full application of current norms, if the company wishes to grow into a leading company in its field
