Purpose: In terms of efficiency and safety, this study attempted to organize data on the operation methods and architectural planning of infectious diseases hospitals. Methods: The results obtained through on-site and interview surveys with hospital officials and medical staffs at four infectious diseases hospitals under construction were summarized based on those original business plans and facility guidelines. Results: First, the operational methods to secure safety and operational efficiency were summarized for each department which are major hospital functions of infectious disease hospitals. Second, as the architectural planning, the characteristics of space and circulation of each department are summarized. For safety of medical staff, negative pressure and non-negative pressure zone have to completely separated. In addition medical staff wears PPE and enters the negative pressure zone and returns in the order of admiral, shower, and gowning in the PPE undressing room after patient treatment. In case of operational efficiency, flexible operation is required in normal and crisis situations. For example, it is important for The Ward to gradually switch to negative pressure beds in times of crisis from normal situation and the outpatient department considers the composition of negative pressure and non-negative pressure outpatient spaces that can operate in parallel even in crisis situations. Implications: Infectious disease hospitals require flexible operation and appropriate facilities for normal and crisis situations.

PURPOSE: This study was carried out to examine the changes in the trunk control ability and hand grip when the abdominal draw-in maneuver using breathing was applied to stroke patients, and provide basic data regarding the trunk stabilization exercise. METHOD: After randomly placing patients in group I-applying the existing abdominal draw-in exercise and group II -applying the abdominal draw-in exercise using breathing, the intervention program was performed ten times per set (five sets per session), once a day, four times a week, for a total of four weeks. For the pre-tests before the intervention, trunk damage and hand grip were measured. After the four weeks of intervention, post-tests were conducted in the same way as the pre-tests for analyzing the study results. RESULTS: Both groups had significant differences in trunk control ability and hand grip (p < .05). The comparison between the two groups showed, significant differences only in the trunk control a ability(p < .05). CONCLUSION: The abdominal draw-in exercise using breathing led to the efficient contraction of abdominal muscles, which implies this is a more effective intervention to improve the trunk control ability.

Purpose: This study tried to present basic data for establishment of facility guidelines and facility certification standards for the comprehensive prevention of infectious diseases in buildings. Methods: This study examines the concept of architectural countermeasures for the prevention of infectious diseases through literature reviews, and then classifies and organizes the countermeasures by viewing the infectious diseases hospitals as the top-level facility in terms of responding to infectious diseases. Results: At first, this study categorized and organized infection prevention countermeasures of infectious disease hospitals, which are the highest level facilities in terms of response to infectious diseases. And by presenting the concept of step-by-step setting of countermeasures for general buildings such as welfare facilities and multi-use facilities, which are lower-level facilities in the aspect of prevention of infectious diseases, this study tried to present basic data for establishing facility guidelines and facility certification standards for comprehensive prevention of infectious diseases in buildings. Implications: In the future, it is expected that spatial changes for the prevention of infectious diseases will spread to general constructions such as public buildings, private buildings, and multi-use facilities, and comprehensive infection prevention facility guidelines are needed.

본 연구는 코로나19 발생 전·후 공공의료를 둘러싼 사회적 인식변화를 뉴스빅데이터를 통해 파악하고자 시도되었다. 뉴스빅데이터는 코로나19 확진자가 처음 발생한 2020년 1월을 기준으로 나누었으며, 코로나19 발생 이전(2018년 1월~2019년 12월, 총 24개월) 40,834건과 코로나19가 발병 이후(2020년 1월~2021년 12월, 총 21개월) 61,761건이었다. 수집된 빅데이터는 R 4.1.1 for Windows를 활용하여 단어 빈도 분석, 연관규칙분석을 실시하였다. 연구결과, 코로나19 발생 전후 뉴스기사에서 공공의료를 둘러싼 핵심어를 비교할 때 코로나19 발생 후에 발생 전보다 큰 폭으로 상승한 단어는 '확산'(664%), '대응'(658%), '의사'(518%), '상황'(504%), '공공병원'(486%), '의료진'(455%), '확충'(324%), '인력'(305%), '어려움'(272%), '정부'(247%)순으로 나타났다. 코로나19 발생 전후 공공의료를 둘러싼 키워드의 연관규칙 분석을 통해서 의료의 패러다임이 일자리 산업에서 감염증 대응을 위한 보건의료로 전환되는 것을 알수 있었다.

Logistics companies have rapidly developed as an important component of economic activities, but due to the special performance management method of logistics companies, problems in performance evaluation are emerging. This paper presented a strategy for improving performance by analyzing the management performance of 19 listed logistics companies in China. Operating expenses, R&D expenses, labor costs, and general management expenses were adopted as input variables, and operating profit and net profit were adopted as output variables. DEA efficiency was assessed by the BBC model from 2016 to 2021 using DEAP 2.1 software. As a result of analyzing the annual management performance, some listed logistics companies showed stable and forward-looking performance results.

This study is an attempt to organize the historical records of the Hanok Church, which played a major role in the history of Korean Protestantism. It was confirmed that research on the theme of Hanok Church was not actively conducted. Through this study, we would like to study the theoretical consideration of the study of Hanok Church and the value of Hanok Church. Based on these results, the purpose was to serve as the basis for theoretical data on the theory of Hanok Church and to actively conduct related research. In addition, by systematizing the cultural values of the Hanok Church, basic information can be provided to establish future cultural values and business utilization plans as modern cultural heritage. Therefore, it is necessary to expand various consultative bodies to preserve Hanok churches around the region and churches and promote various projects to improve the environment for the preservation of Hanok churches. Lastly, I think efforts for long-term preservation and related research of the Hanok Church are continuously needed.

This study is meaningful in figuring out how much the Korean people's awareness of hanok has increased even though interest in hanok has also increased due to the Korean Wave craze. Therefore, with respect to the exterior of hanok, which is visually recognized first, the level of experts and ordinary people is grasped through a semantic discrimination scale, and the degree of visual recognition is to be investigated centering on the color image of hanok buildings. This is the process of thinking about how the Korean image should be reflected in the design, and we want to suggest the direction that modern hanok should go. The study compared and analyzed the difference in visual color based on the elevation of the hanok using a 7-point and 5-point scale method for the general public and experts, and utilized the IRI adjective vocabulary scale and the color matching image scale to construct new hanoks with insufficient differences in appearance and shape. It can be applied to design and image preservation and construction of existing hanok.
