RESUMO
Hospitals need to identify issues of greater importance on waste management because the implementation of many different strategies may lead to an unconscious increase in costs. Accordingly, the purpose of this study is to define the most effective waste management strategies in the service industry. For this purpose, a novel fuzzy decision-making model is proposed that has two different stages. In this context, six JCI-based indicators are weighted by using sine trigonometric fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) methodology. Additionally, a comparative evaluation has also been conducted with sine trigonometric fuzzy Criteria Importance Through Intercriteria Correlation (CRITIC) technique to check the reliability of the findings. On the other hand, five different strategy alternatives are selected by considering the principles of the integrated waste management hierarchy approach. These items are evaluated by considering sine trigonometric fuzzy Technique for Order Preference by Similarity (TOPSIS). On the other side, these factors are also ranked with the help of sine trigonometric fuzzy Additive Ratio Assessment (ARAS) to test the consistency of the results. The main contribution is that prior strategies can be presented to the hospitals to have appropriate waste management process by defining the most important factors. Criteria weighting and alternative ranking results are the same in all combinations. Therefore, it is seen that the proposed model creates coherent and consistent results. It is defined that efficient storage of waste is the key issue to have effective waste management process. Moreover, 'reduce' is found as the most critical stage of this process.
RESUMO
BACKGROUND: In metropolitans, where public transportation is used extensively, bus drivers are one of the occupational groups with a high risk of contracting COVID-19. OBJECTIVE: This study aimed to assess the difference between the clinical status of a group of bus drivers and field officers with COVID-19 on public transportation lines in Istanbul. METHODS: The study was conducted with 477 male volunteer participants. COVID-19 was confirmed through a positive nasopharyngeal culture sample using the real-time PCR test. Demographic information, biochemical parameters, clinical status, and the use of nutritional supplements were compared between those who recovered from COVID-19 at home or in the hospital. RESULTS: The body mass indexes (BMI) of 83.9% of individuals was above normal and 75.4% were treated for the disease at home. There were significant differences in terms of age, BMI, weight loss, smoking, use of nutritional supplements, blood glucose levels and vitamin B12 values. However, there was no significant difference between the types of nutritional supplements used or other biochemical parameters. CONCLUSION: It was determined that those who survived the disease at home were younger and had a lower BMI. It is important for both individuals and for general public health to create healthy working environments, especially for bus drivers, who have a high risk of COVID-19 contamination and transmission due to their long exposure time.
