Purpose: This study aims to identify the level of subjective noise perception among School Meal Facility Workers and analyze the relationship between subjective noise perception and insomnia, as well as the factors affecting insomnia. Methods: School meal facility workers were surveyed from November 1 to December 31, 2021, and 717 people were selected as participants for the study. Using SPSS/WIN 25.0, t-test, x2 test, and multiple logistic regression analysis were conducted. The Korean Insomnia Severity Index (ISI-K) was used to evaluate insomnia. Results: The variables that showed significant differences in insomnia in general characteristics, health-related characteristics, subjective health perception, and subjective noise perception of the study participants were mental disorders such as subjective health perception, work stress, depression, etc., gastrointestinal disorders, and subjective noise perception, among which subjective health perception, mental disorders such as depression, and subjective noise perception were analyzed as factors influencing insomnia. Conclusion: To improve the quality of insomnia and sleep among school meal facility workers, there is a need to improve healthcare, emotional management, and noisy work environments.

Korean Elementary School Learners’ L2 Motivational Self System and the Moderating Effects of Gender and Grade Differences

정윤주 언어과학회 2015 언어과학연구 Vol.0 No.74

This article aims to explore the impact that the relationships among the eight motivational factors associated with Taguchi, Magid, and Papi’s (2009) adaptation of the L2 Motivational Self System (criterion measures, ideal L2 self, ought-to L2 self, attitudes to learning English, attitudes to L2 culture and community, instrumentality-promotion, instrumentality- prevention, and family influence) have on the second language learning motivation of Korean elementary school learners (KESL). Moreover, it sought to examine whether the students’ gender and grade moderated the relationships among these factors. Methodologically, this paper employs structural equation modeling analysis of the data obtained from 845 Korean students in the fourth, fifth, and sixth grades. The study’s results revealed that: 1) ideal L2 self had the most bearing on the learners’ motivation, 2) attitude to learning English was a significant predictor for L2 learning motivation, 3) gender did not have any substantial bearing on the L2 Motivational Self System for KESL, while grade had considerable moderating effects, and 4) ideal L2 self was significantly more strongly associated with criterion measures for fourth graders than it was for sixth graders.

대학생 유튜브 브이로그(Vlog) 시청자의 시청동기와 지속시청의도 관계 분석 -시청몰입과 시청만족을 매개변인으로-

정윤주,김종무 커뮤니케이션디자인학회(구 시각디자인학회) 2020 커뮤니케이션 디자인학연구 Vol.71 No.-

본 연구는 유튜브(YouTube) 브이로그(Vlog)를 시청하는 대학생들의 시청동기 요인을 파악하고, 시청동기가 시청만족, 시청몰입, 지속시청의도에 미치는 영향과 시청동기와 지속시청의도간의 관계에서 시청 몰입과 시청 만족이 매개역할을 하는지에 대해 분석하였다. 연구를 위해 2019년 8월 14일부터 9월 14일까지 온라인 설문 후 오류가 없는 332부를 최종 분석에 사용하였다. 분석결과 첫째, 유튜브 브이로그 시청동기 요인은 외로움 해소, 매개된 관음증, 시간 보내기, 오락추구 4가지로 구분되었다. 둘째, 유튜브 브이로그 외로움해소 시청동기 요인은 시청몰입에 정(+)적인 영향을 미치지만, 시청만족과 지속시청의도에는 영향을 미치지 않는 것으로 나타났다. 셋째, 유튜브 브이로그 매개된 관음증 시청동기 요인은 시청몰입, 시청만족, 지속시청의도에 정(+)적인 영향을 미치는 것으로 나타났다. 넷째, 유튜브 브이로그 시간보내기 시청동기 요인은 시청몰입에 부(-)적인 영향을 미치고, 시청만족과 지속시청의도에는 영향을 미치지 않는 것으로 나타났다. 다섯째, 유튜브 브이로그 오락추구 시청동기 요인은 시청몰입, 시청만족, 지속시청의도에 정(+)적인 영향을 미치는 것으로 나타났다. 여섯째, 시청몰입은 매개된 관음증, 오락추구 시청동기 요인과 지속시청의도 관계에서 부분매개 효과를 갖고 있었다. 마지막으로, 시청만족은 매개된 관음증, 오락추구 시청동기 요인과 지속시청의도 관계에서 완전매개효과를 갖고 있었다. 즉, 매개된 관음증, 오락추구 시청동기 요인은 시청만족의 매개효과가 없으면 지속시청의도에 직접적으로 영향을 주지 못한다. 이러한 연구 결과는 대학생 유튜브 브이로그 시청자에 대한 연구가 부족한 상황에서 수용자의 이용과 충족 이론을 기반으로 실증적으로 검증함으로써 연구의 폭을 넓혔음에 의의를 가지며, 기존 선행연구의 전통/뉴미디어의 시청동기에서 파악할 수 없었던 ‘매개된 관음증’동기가 추가되었다는 점이 이 연구의 의의를 갖는다. This thesis helps understand viewing motivation factors of undergraduates who watch a Vlog on YouTube, and suggests effects of viewing motivation about viewing satisfaction, viewing flow, and persistent viewing intention. Also, in relation of viewing motivation and persistent viewing intention, It has a purpose to reveal their relationship on viewing flow and viewing satisfaction Empirically do roles as intermediation. For that, we did a questionnaire on the Internet from 14 Aug 2019 to 14 Sep 2019 and analyzed the data of 332 papers were used to an analysis of result except some papers written by unfaithful people and someone who haven't ever watched YouTube. First of all, the analysis results show that viewing motivation of watching a Vlog on YouTube was divided into 4 factors such as loneliness alleviation, mediated voyeurism, killing time, and entertainment motivation. Second, It is represented that loneliness alleviation by watching a Vlog on YouTube has a positive effect to viewing flow, but It doesn’t have positive effect to viewing satisfaction and persistent viewing intention. Third, It is shown that mediated voyeurism by watching a Vlog on YouTube has a positive effect to viewing flow, viewing satisfaction, and persistent viewing intention. Forth, It is presented that killing time has a negative effect to viewing flow, and viewing satisfaction and persistent viewing intention don’t have any effect to killing time motivation. Fifth, It is signified that entertainment motivation by watching a Vlog on YouTube has a positive effect to viewing flow, viewing satisfaction, and persistent viewing intention. Sixth, viewing flow have a partial mediation about a relationship of mediated voyeurism, entertainment motivation, and persistent viewing intention. Finally, viewing satisfaction have a perfect mediation about a relationship of mediated voyeurism, entertainment motivation, and persistent viewing intention. In other words, mediated voyeurism and entertainment motivation doesn’t have any direct effect to viewrs’ satisfaction, if it doesn’t have an mediated effect of viewing satisfaction. Like this results, the research of viewers who watch a Vlog on YouTube has a further significance. Because, there is scarce information about watching a Vlog on YouTube and precedented research was rarely conducted. Based on receiver’s Uses and Gratifications theory, It has a significance, because this research empirically validities a hypothesis and widens widths of a study. Also, this research has a significance, because ‘mediated voyeurism’was added which couldn’t be grasped by studying viewing motivation of traditional/new media.

Layer of Protection Analysis를 이용한 화학공정의 위험성 평가와 적절한 Protection Layer의 설정에 관한 연구

정윤주,김구회,윤인섭 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.1

Layer of Protection Analysis(LOPA)는 피해 예측과 위험성 평가의 한 방법으로 정성적 위험성 평가와 정량적 위험성 평가의 사이에 있다고 할 수 있다. LOPA는 Decision-making 시 사고를 방지하기 위해 존재하거나 제안된 protection layer의 타당성을 결정할 수 있게 해주므로 회사의 Risk-decision criteria와 이상적으로 잘 어울린다. LOPA는 공정의 Safety instrumented system(SIS)에서 적당한Safety integrity level(SIL)을 설정할 수 있게 하는 recognized technique이다. 본 연구에서는 이러한 LOPA를 이용하여 화학공정에서의 위험을 예측 및 분석하고, 위험을 감소시킬 수 있는 적절한 Protection Layer를 설정해 보았다.

램프와 안정기가 결합된 8파장 이중화 램프에 관한 연구개발

정윤주,김민수 한국기계기술학회 2017 한국기계기술학회지 Vol.19 No.1

This study was to develop the products that the Lamp and Ballast are combined for the purpose of easy installation to complement the difficulty of the installation process due to the structure of existing product which the lamp and the Ballast are separated, and that have 8-wavelengths dual-lamp structure such as solar, an advantage of more than 3 times longer life than fluorescent lamp and immediately lighting. This study developed the commercialized products that can prevent the environmental pollution caused by low efficiency and short life time of existing Lamps, and can replace the LED Lighting products which has high Glare index with high price, has also developed the variety of application for industrial, commercial, indoor and military. The applied product are Street lights, Security lights, Flood lights, Indoor lights and lights for fishing. This study solved the optimum distribution and placement of components considering the lightest weight first and thermal interference caused by combination of lamp and ballast by thermal release through applying the double bulkhead design of ballast box, and implemented the high efficiency Eco-friendly products with excellent visibility which can be applied and used for indoor and outdoor both place through high temperature and high humidity test, which has an advantage of 8-wavelengths of same spectrum of solar through the initial trial production.
