RESUMO
After the detection of the first official case diagnosed with COVID-19 on March 2020, the new package called as "Economic Stability Shield” have been implemented in Turkey to minimize the effects of the pandemic. As in all sectors, the epidemic caused various changes in the real estate sector. The demands of citizens who stayed in homes for a long time during the epidemic period have also changed when buying a house. This study aims to investigate the importance of selection criteria for buying a house criterion in the real estate sector and to determine the most suitable house of via a Multi-Criteria Decision Making (MCDM) approach. By integrating Fuzzy Analytic Hierarchy Process (FAHP) and Multi-Attribute Ideal Real Comparative Analysis (FMAIRCA), the assessment criteria of buying house and suitable houses are evaluated. While making this evaluation, the weights of the criteria are obtained by pairwise comparisons under fuzzy environment through collected from five households living in Konya. Next, the FMAIRCA method is used to rank the candidate houses according to the views of the households. As a result of the study, it has been determined that the criteria of eligibility for credit are the most important criteria. For the case study, we perform a comparative analysis on the performance of fuzzy TOPSIS and fuzzy VIKOR in buying a house. Our comparative analysis for this case study shows that the three fuzzy MCDM methods achieve the identical rankings. © 2023 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.
RESUMO
Objectives: Coronavirus disease 2019 (COVID-19) is seen not only as a disease, but it is also defined by a series of met- aphors: mysterious, evil, an invisible enemy, an insidious danger, and a democratic virus. This study was conducted to analyze the nurses' perceptions of COVID-19 through metaphors.Methods: This qualitative research was planned as a descriptive phenomenological approach. Twenty-eight nurses working in the COVID-19 intensive care unit (ICU) participated in the study. The metaphor-based data collection pro- cess was carried out with five open-ended questions. The data were analyzed through a thematic analysis. The Consol- idated Criteria for Reporting Qualitative Research Checklist was used to analyze this study.Results: Most military and fatigue related to the time nurses work in intensive care;Hero and nightmare of patient care with COVID-19;distance and restlessness in family relationships;their mental health darkroom and fatigue;COVID-19 as an insidious enemy and infinity. A total of 128 metaphors were produced.Conclusion: Working during the COVID-19 epidemic, COVID-19 ICU nurses exhibit unfavorable approaches toward their jobs, family relationships, and mental health. Improving the working conditions of ICU nurses and considering their desires will help contribute to a favorable direction.
RESUMO
Depending on whether or not there is a chaotic condition, the outcomes of decision problems and the factors determining the outcomes of the problem may differ. Different criteria can be introduced for decision makers' preferences in chaotic conditions, and the importance levels of the criterion can fluctuate. Despite the fact that the COVID-19 epidemic has had an impact on the aviation industry, air cargo transportation has performed well during this time. From this perspective, the impact of chaotic events on the selection of an air freight firm is investigated in this study. With Multi-Criteria Decision Making (MCDM) methodologies, a new decision-making framework is proposed, which is an effective solution method for choice makers to finalize decision problems. The Bayesian BWM (Best-Worst) method, which is one of the new ways, is used to establish the criterion weights, while the WASPAS method is utilized to rank the air cargo businesses, due to the more sensitive reaction of the newly proposed methods. As a result, these two approaches are combined, and the ranking results are compared to the TOPSIS and COPRAS methods, with the outcomes examined. As a result, in a chaotic environment, the most essential consideration for selecting an air freight company appears to be economic criteria. © 2023 Gazi Universitesi Muhendislik-Mimarlik.
