This study aims to discuss sustainable fashion trends and sustainable design directions that fashion companies are practicing with ESG in the post-corona new normal era. As a research method, this study examined sustainable fashion trends and ESG practices through empirical case studies focusing on each fashion brand's website, including previous research and literature research, using materials such as newspapers and magazines. As for ESG practice plans, they were divided into four categories: technology orientation, design orientation, consumption orientation, and social value pursuit orientation. The sustainable fashion trends were also divided into four categories. First, the trend exhibits cyclical sustainability using pro-environmental materials, such as pro-environmental fibers, recycled fibers, biodegradable fibers. Second, high sensitivity and rare value sustainability were shown using reuse and upcycling. Third, consumption-oriented trends were promoted through slow fashion. Fourth, in order to realize eco-friendly sustainable fashion and ESG as practical ways to pursue social values, there is a trend of integrating sustainability through changes in perception considering people, society, and the environment. Beyond spreading concern about value consumption trends and the environment, it presents a direction for future industries concerning core values with social roles, responsibility, and ethical awareness from various perspectives.

Objectives The purpose of this study is to analyze recent clinical studies on traditional Chinese medicine (TCM) treatment for pediatric inguinal hernia and pediatric rectal prolapse in China, and to seek better methods to treat and to study for Inguinal hernia and Rectal prolapse in Korea. Methods We searched the clinical studies from the China National Knowledge Infrastructure (CNKI) that were published between January 2000 to February 2020 by key words '疝气', '直腸脫出', '直腸脫垂', '脫肛', '小腸疝', '腹股溝疝', '儿童', '小儿', '少儿', '幼年', '治療', '中医治療', '中藥', '中医藥', '顆粒', '膠囊', '自擬', '湯', '丸', '散', '方'. We analyzed the literatures in regards to the treatment methods and results. Results Among the 193 searched studies, 10 randomized controlled trials were selected and analyzed. In most of the studies, the effectiveness of the traditional Chinese medicine (TCM) treatment on inguinal hernia and rectal prolapse was significantly high. Conclusions Based on the results of the clinical studies from China, use of the TCM for the treatment of inguinal hernia and rectal prolapse has been shown to be effective in relieving symptoms. Also, based on the result of this study, it will be possible to widen the scope of the TCM treatment on inguinal hernia and rectal prolapse. Additional clinical studies and experimental studies are needed to be performed to solidify these findings. The TCM has been shown as an effective treatment for pediatrics as well. These research results can be utilized in other clinical studies and in treatment.

A long-term change in the evaporation rate have an influence on the hydrologic processes at the interface between the land surface-air and crop yield. Several previous studies have reported declines in pan evaporation rate, while actual evaporation rate is expected to increase due to anthropogenic global change in the future. The decreasing trend of pan evaporation rate might be involved with global warming and accordingly the trend of annual pan evaporation rate also needs to be checked here in Korea. In this study, 14 points of pan evaporation observation are intensively studied to investigate the trend of pan evaporation for the time period of 1970-2000. Annual pan evaporation is decreasing at the rate of 1.6mm/yr, which corresponds to approximately 50mm for 30 years. Annual pan evaporation rate is larger by $\sim10%$ at the coastal area and decreasing rate is faster as -2.46 mm/yr per year, while that is -0.82 mm/yr per year at the in-land area. The results of the Mann-Kendall trend test shows 4 points are decreasing and 10 points are unchanged with 95% confidence interval. But national annual average values show the decreasing trend of pan evaporation rate as a whole, which corresponds to general trend all over the world. This study will contribute to a variety of studies on water resources, hydrology, agricultural engineering, meteorology, and coastal engineering in association with future global climate change.

The purpose of this study is to examine the trend of the studies on Korean social welfare administration over a recent 10 year period. Employing both network analysis and content analysis, which are representative statistical strategies to identify research trends, we analyzed 221 articles published in the Journal of Korean Social Welfare Administration from 2005 to 2014. The major findings were as follows; First, we found two clusters -"social (welfare) service" and "social welfare organization"- in the studies of social welfare administration. In addition, more than 80% of articles are mainly related with human resource management, including job satisfaction, organizational commitment, and so forth. Second, the newly emerging academic subjects such as social enterprise and community network appeared to be done independently of traditional subjects. Third, the proportion of quantitative studies being focused on human resources was overwhelmingly high compared to the other types of studies; therefore, there are a few studies using qualitative or mixed method, evidence based practice, and discourse studies. In addition, the studies of the rural areas, which are a blind spot of the social service delivery system, and the studies about information management, financial management, marketing, organization innovation rarely appeared, despite their significance.

A number of studies on the educational influence of drama and theatre have increased since the 1990s in South Korea. These days, more Korean researchers seem to have recognised the educational influence of drama and theatre than before. At this time, it is meaningful to look into how the domestic trend of studies has changed and developed over the past thirty years. This paper especially adopted a bibliometric method to analyse the trend by time of studies from the late 1990s to 2017. In addition, target age, research topic and research approach of each study were investigated. Some of terminologies particularly used in South Korea were also defined to help young researchers' understanding in this paper. In detail, the total number of studies for the last thirty years is 225 and the first domestic study on the educational power of drama and theatre was published in 1994. In the 2000s, there was quantitative expansion in terms of the number of studies and topics. Eventually pragmatic and integrated features of the studies were found in the 2010s. It is anticipated that the pragmatic and integrated features of the studies will be stimulated to fit into the need of the time. Until now, the most fevered research target age was mainly primary school students. However, it would be possible to widen a target age range in the future. It should be considered having collaboration among researchers who have different expertises for conducting higher quality studies.

대중적 건설중장비로서의 유압굴삭기는 1990년대 이후로 탈산업화(post-industrialization)의 영향을 받아, 형태나 색채에 있어서 변화를 시작한다. 이는 일반 소비재 분야에 비하여 다소 늦은 편이라 할 수 있다. 그 이유는 건설중장비 특성상 제한된 사용 충과 사용환경으로 인한 제품개발기간(PDT)과 제품수명주기(PLC)가 길고, 제품개발 비용이 상대적으로 거대하기 때문이다.(중략)

트랜드는 개별적, 일시적 유행과는 다른 것이며 보다 광의적이고 포괄적이며 커다란 생명력을 가진 것이다. 눈에 보이는 현상보다는 민족성이나 인간의 본성과 같은 표현하기 힘들거나, 인식하기 힘든 요인으로 말미암아 기존의 여론조사나 소비자 성향을 분석하는 트랜드 트레킹 방법에는 한계가 있다고 할 수 있다. (중략)

신상품 개발을 위한 트랜드 이미지의 수집과 분석(타운워칭, 캐털로그 분석 등)은 이미 디자인 전개과정에 깊숙히 자리잡고 있는 기법이다. 그러나 대부분의 경우 트랜드 이미지의 수집은 디자이너의 직관에 의존하는 경우가 많았기 때문에 실질적인 시장상황을 반영한다고 하기에는 다소 힘들었던 것이 사실이다. (중략)
