For acquiring the specific characteristics of solid metal, the solid material used for various heat exchangers or reactors is treated by heating and cooling process before forming. In the process of heat treatment, water at ambient temperature is used for cooling. When the solid metal with high temperature is cooled by water, there occurs sudden boiling of water at the surface of solid metal. It is important to control cooling time and cooling speed for the required characteristics of solid material. In this study, the boiling phenomenon with rapid cooling in water is analyzed by experiment and numerical analysis for control of heat treatment process. When the high temperature of solid metal is cooled by ambient water, the unsteady subcooled boiling model is suitable for numerical analysis instead of saturated boiling model and there exists considerable time delay before rapid heat transfer by boiling process.

하지수(Ha, Jisoo),염지숙(Yeom, Jisook) 한국열린교육학회 2019 열린교육연구 Vol.27 No.2

이 연구에서는 사립유치원 교사의 퇴직과 복직 경험을 탐구하고 이러한 퇴직과 복직 경험을 개인적 맥락, 유아교육기관의 맥락, 제도적 맥락 내에서 이해하고자 하였다. 이 연구의 목적을 달성하기 위해, 질적 사례 연구방법을 활용하여 퇴직과 복직을 경험하고 현재 사립유치원에 재직 중인 2명의 교사를 연구 참여자로 선정하였다. 권 교사와 김 교사 각각 7회와 6회의 면담을 4개월에 걸쳐 진행하였다. 연구결과, 권 교사는 실습생처럼 대우받는 초임교사로서, 부담임과 종일반교사로서의 역할에 갈등을 느껴 퇴직한 후, 재충전의 시간을 갖고, 지인의 요청으로 퇴직 8개월 만에 다시 사립유치원으로 복직하였다. 권 교사의 퇴직과 복직경험은 개인적으로 치유와 휴식의 시간이었고, 복직한 유치원의 긍정적인 조직풍토와 인적환경이 권 교사의 성공적 복직에 매우 중요했으며, 미흡한 복직지원제도의 필요성을 상기시켜주었다. 김 교사는 유치원의 상황과 개인적 상황으로 퇴직과 복직을 반복하였는데, 가장 마지막 퇴직은 육아를 위해서였다. 김 교사는 퇴직 기간 동안 온전히 육아에 전념하였으며, 이는 복직한 유치원에서 교사로서 ‘돌봄’ 전문성을 발휘하는 데 도움이 되었다. 김 교사는 퇴직과 복직을 반복하는 동안 양육경험으로부터 복직에 필요한 전문성을 기를 수 있었으며, 복직한 유치원에서 원장의 배려로 일과 양육을 함께 할수 있었고, 변화된 유치원 환경에 적응하기 위해 연수를 통해 자신을 발전시키려고 노력했다. 연구결과에 기초하여, 소진을 막기 위한 적절한 휴식 및 휴가 보장, 복직을 원하는 교사를 위한 정보제공과 지원, 복직교사를 대상으로 한 체계적인 연수 제공 등을 제안하였다. This study aims to examine experiences the private kindergarten teachers underwent in the course of resignation and reinstatement, and the meanings of such experiences in individual, education institutional, and institutional contexts. The data was collected for 4 months from 2 private kindergarten teachers, Ms. Kwon and Ms. Kim, who have experienced both resignation and reinstatement. The findings are as follows. Ms. Kwon was not able to adapt to her job initially due to various difficulties resulting from being a newcomer to the private kindergarten . Yet after 8 months of rest and some wandering, she decided to become a kindergarten teacher again. After being reinstated, through the cooperative atmosphere of that kindergarten, she once again established her identity. Ms. Kim worked as an experienced teacher at a childcare center (Sky Kindergarten), but after getting married she resigned due to her new married life situation. After having a 5-year break, she went back to teaching and was reinstated at Sky Kindergarten, and is exerting utmost efforts on her given role at work while acknowledging the conflicts arising from the two roles she has in life as both a mother and teacher. By resigning earlier in their careers, these 2 teachers were not only able to relieve various stress accumulated while working at kindergarten, but also were able to recharge themselves by having the much-needed time of their own, which, in turn, led to a more positive perspective on their previous work experiences. Therefore private kindergartens should, rather than looking at the resignation of a kindergarten teacher from a strictly negative perspective, consider offering teachers opportunities to rest and develop themselves during leaves of absence instead of a permanent job loss. Lastly, in order to prevent permanent resignation and loss of kindergarten teachers and support the reinstatement of those teachers with gaps in their career, it may be necessary to establish a healthy organizational culture by forming sound relationships among the members of a kindergarten, and provide adequate support to the teachers in development phases of their careers. And, it is urgent that social perceptions change, to acknowledge the individual lives and needs of married teachers as well.

This article surveys the meaning and history of fashion museum exhibitions to understand the characteristics that make a fashion museum exhibition special. It explores dress museology and fashion museology in theory, and practice across a range of international case studies that include the Costume Institute at the Metropolitan Museum of Art in New York, Mode Museum in Antwerp, and the Victoria and Albert Museum in London. In particular, it examines how curatorial intervention has developed the interpretation and display techniques of dress within the context of the museum or gallery as well as how fashion has made museums accessible to diverse audiences. For a specific case study, we review the types and roles of fashion exhibitions organized by the Simone Handbag Museum, Seoul. It is the first handbag-centered fashion museum in the world as well as one of the most representative local fashion museums. The museum collection includes fashionable western handbags from rare specimens of the 15^th century to the latest bags of the 21 ^st century, and presents a history of changing fashion cycles and the major socio-cultural shifts that have profoundly affected women`s lives in public spaces. Exhibitions show the perspective to a range of curatorial methodologies and show the innovative approaches towards collections and displays with broader fashion issues such as gender, materialism and technology. The article is to help encourage further scholar discourse between fashion museum exhibitions and fashion museology.

In this research, we conducted an empirical study using the theory of sociologist Jean Baudrillard to examine the phenomenon of contemporary people in Korea acquiring tattoos. The researcher classified the consumption behavior of modern society, as described by Baudrillard in The Consumer Society, into three keyword phrases: consumption by personal taste, coded consumption, and recyclage of consumption. Using this as the premise of the study, 18 men and women in their 20s and 30s completed questionnaires and interviews, and the results supported labeling tattoo consumption as consumption by personal taste, tattoos as coded consumption, and recyclage of tattoo consumption, similar to the consumption pattern that Baudrillard sees. First, the younger generations have consumed tattoos according to their personal preferences. They express themselves by tattooing for self-complacency, self-marking, pursuing individuality, overcoming the appearance complex, and seeking pleasure. Second, they have consumed socially coded tattoos. They say that tattoos domestically act as negative codes and symbolize individuals. Although tattoos are a symbol of artists who are relatively free from social norms, they are still a symbol of social misfits created as such by negative perceptions. Third, the pattern of tattoo consumption is like that of contemporary consumption. Tattoos already have become part of popular culture in Korea, and there has been a changing trend in tattoo culture. This study has significance in that tattoos were regarded as a consumption behavior that deviated, from the perspective of deviance. That phenomenon of today's tattoo culture of today was confirmed through the empirical study.

This study aims to examine how the appearance management of Korean middle-aged men has changed in newspaper articles reflecting the socio-cultural trend in Korea from 1960 to 2019. The study utilized quantitative analysis through text mining of Textom and content analysis of newspaper articles. Consequently, appearance management by Korean middle-aged men moved to exteriors including face, skin, body type and fashion from internal aspects like health. The words ‘jeans’, ‘No More Uncle’ show the changed appearance management of Korean middle-aged men. However, the emergence of the term ‘Ajae’ reveals that a gap between middle-aged men brought up under the traditional values and young generations and their collision in values manifests even in appearance management. The changes in key words related to the appearance management of Korean middle-aged men over about 70 years symbolically represent the perceptions of middle-aged men according to changes in socio-cultural background and ideology. This study has academic significance as historical data on the appearance and fashion of Korean middle-aged men by deriving various meanings of their appearance while looking at the changes in the unique characteristics of Korean middle-aged men from a diachronic perspective.

Technological change leads to a value shift in human society. Various cultural experiences through the digital paradigm influence the expression of fashion. This article considers fashion film as a new form for presenting fashion and explores the distinctiveness of expression in digital fashion film. For the methodology, a literature review was conducted to examine the concepts and features of digital fashion film and metareality. Empirical research was also performed by drawing from Nick Knight’s digital films, “Sans Couture”, “#asif”, and “The Elegant Universe” and by specifically analyzing the classification of the themes, visuals, and auditory expression. The results are as follows. The proliferation of fashion film has accelerated in the internet environment. New media in the digital era allows images to become more realistic and variable through immaterial conversion. Metareality is the notion of a reality beyond existence. A metarealistic image maintains the metaphysical nature of an object and transcends empirical appearance. It possesses immaterial, transboundary, and multidimensional features, and the image is realized by digital technology. The expression analysis identifies the metareality expressed in contemporary fashion film appearing as atypical forms, irrational combinations, and the playfulness of motion. It shows a positive attitude, transcending the immaterial limit of reality toward fashion. This study indicates how fashion as products challenges the metaphysical transformation in the digital era. The exploration of metareality in digital fashion film promotes a wider perspective and understanding of the concept of fashion.

While fashion is a major medium of expressing individuality and identity, it also has been influenced by the socio-cultural norm. This might be the reason that the discussions about fashion and gender have been made steadily. In this study, we purposed to pay attention to the characteristics of the use of clothing of gender minorities in everyday situations, from the viewpoint of focused ethnography. Hypothesizing that gendered clothing norms and cultural norms will affect the use of clothing in everyday situations, we focused on identifying the aspects of how the norm works in gender minorities’ everyday lives and revealing its specificity of Korea’s social-cultural influence. According to the study, gender minorities express their clothing based on the attitude toward gendered clothing norms, which has been developed over time. The attitude of gender minorities toward gender-based clothing norms was divided into compliance, individuality and compromise, non-compliance and deviation. At the same time the costume expression patterns were divided into individuality-oriented, physical-management, customary gender-imitating, and neutral gender-image-seeking types depending on the response attitude. Relatively in common, the candidates clothed based on the social awareness reflect their collective identity through clothing and express individual's gender at the same time. By using clothes to perform gender in everyday situations, candidates’ gender performativity through clothing creates cracks among gendered clothing norm and extend it, implying the possibility of the emergence of new norm. This result implicates that the study has expanded the potential of fashion to express sexuality and gender, by inspecting costume styles of various Korean gender minorities. In addition, it is meaningful when planning and developing fashion products that can express various gender and sexuality by approaching the concerns experienced when using clothes in daily life. But there still to be identified more detailed properties of each gender minority category and the segmental characteristics. Also, the study couldn’t include many participants from the ‘closet’, so the results can’t be generalized for all the gender minorities.
