ABSTRACT
Due to the coronavirus (COVID-19) emerging in Wuhan, China, most employees had to work from home in unsuitable conditions. Employees are more affected by the factors that cause musculoskeletal disorders when working from home using information and communication technologies. The aim of the study was to determine the ergonomic risks related to the musculoskeletal system that teachers, who made up a large number of employees working in the service sector during the COVID-19 period, may be exposed to working remotely. For this, first of all, in line with the literature review and expert opinions, physical, psychosocial, and individual risk factors related to the musculoskeletal system were determined and the weight of the risk factors was calculated with the Analytic Network Process method. Work duration, posture, and physical environment constituted the highest risk factor among physical factors. With the Preference Ranking Organization Method for Enrichment Evaluations, information and communication devices were ranked according to their effects on the user. The ranking is determined by mobile phones, tablets, laptops, and desktop computers. It is concluded that it is necessary to pay attention to the risk factors specified in the use of these devices in order to prevent musculoskeletal system damage.

ABSTRACT
BACKGROUND: The treatment of the COVID-19 epidemic, whose contagious features are changing day by day, is the most current problem today throughout of the world. In order to be protected from COVID-19 and reduce its spread, it is of great importance to follow the rules such as mask, distance and hygiene. In addition, one of the most important ways to prevent the epidemic is to develop population immunity. The most important tool in having population immunity is vaccination. AIMS: During the COVID-19 pandemic, there have been problems in the supply process of many products in food and health sectors. Vaccine is also one of the most difficult tools to supply. In this context, the study focused on the selection of the vaccine provided by the countries within the scope of population vaccination studies. MATERIALS & METHODS: At the selection point, the criteria affecting the purchasing process were determined and the weights of these criteria were calculated using the AHP method. Then, the criteria weights obtained were used to rank the alternatives in an integrated manner in the Preference Ranking Organization Method for Enrichment of Evaluations (PROMETHEE) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. The results of both methods were analyzed comparatively. RESULTS: According to the TOPSIS Method, the first alternative is Oxford-AstraZeneca for all countries, and BioNTech for all countries in the PROMETHEE method. DISCUSSION: The vaccine storage conditions criterion is the most important in vaccine supply. The criterion with the lowest importance is Supply Cost. It has been revealed that cost elements remain in the background under pandemic conditions. CONCLUSION: Vaccine evaluation studies and policy recommendations are presented by considering public health in the selection of vaccine alternatives.
