호모프탈산 무수물(1또는 2)과 디에틸 아조디카르복시산 및 에틸 아릴메티리덴카르밤산과의 고리화첨가반응을 검토하였다. 전자의 반응에서는 2,3--디에톡시카르보닐-2,3-디히드로-1-히드록시프탈라진들(3 및 4)이 생성되었으며, 후자의 반응에서는 3-아릴-4카르복시-2-에톡시카르보닐-3,4-디히드로-1(2H)-이소퀴놀린온들(5~10)이 생성되었다. The cycloaddition between homophthalic anhydrides (1 or 2) and diethyl azodicarboxylate and ethyl arylmetbyldenecarbamates was investigated. The former led to 2,3-diethoxycarbonyl-2,3-dihydro-1-hydroxyphthalazines (3 and 4), while the latter gave 3-aryl-4-carboxy-2-ethoxycarbonyl-3,4-dihydro-1(2H) isoquinolinones (5∼10).

청소년의 차별경험이 자살생각에 미치는 영향에서 부모와의 소통과 학교생활의 조절된 매개효과 연구

이윤영(Youn Young Lee),권승아(Seung A Kwon) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.15

목적 본 연구는 청소년의 차별경험과 자살생각의 관계에 있어 부모와의 소통과 학교생활의 조절된 매개효과를 검정하는 것을 목적으로 한다. 방법 이를 위하여 한국청소년정책연구원에서 실시한 ‘2019 아동⋅청소년 인권실태 조사’ 자료 중 중⋅고등학생 6,291명의 자료를 분석에 활용하였으며, 차별경험을 독립 변수로, 자살생각을 종속 변수로, 부모와의 소통을 매개변수로, 학교생활을 조절변수로 연구 모형을 설정하였다. 결과 분석 결과 청소년의 차별경험은 자살생각에 정적인 영향을 미쳤으며, 이때 부모와의 소통은 차별경험과 자살생각을 매개하였다. 또한 학교생활은 차별경험과 부모와의 소통 관계를 조절하고 있으며, 더불어 학교생활은 차별경험과 부모와의 소통, 자살생각의 관계를 조절하였다. 결론 청소년의 학교생활이 긍정적이면 차별경험이 부모와의 소통을 경유하여 자살생각을 증가시키는 매개효과가 완화되는 조절된 매개효과를 확인하였으므로 본 연구 결과에 근거하여 청소년의 차별경험 피해를 궁극적으로 낮추기 위한 방안으로 학교와 가정에서의 위계적이고 일방적인 소통을 지양하고, 학교와 가정이 연계된 학습자 중심의 참여교육 강화를 제시하는 바이다. Objectives The purpose of this study is to test the moderated mediating effects of communication with parents and school life on relations between adolescents' discrimination experiences and suicidal ideation. Methods The study analyzed the data of 6,291 middle and high school students from “2019 Survey on the Human Rights of Children and Adolescents” by the National Youth Policy Institute and set discrimination experiences as an independent variable, suicidal ideation as a dependent variable, communication with parents as a parameter, and school life as a moderating variable in the research model. Results The analysis results show that adolescents' discrimination experiences had positive effects on their suicidal ideation and that communication with parents played a mediating role between them. School life had moderating effects between discrimination experiences and communication with parents and also between discrimination experiences and communication with parents and suicidal ideation. Conclusions School life had moderated mediating effects as the positive school life of adolescents alleviated the mediating effects of discrimination experiences increasing suicidal ideation via communication with parents. Based on the findings, the study proposes to refrain from hierarchical and one-sided communication at home and school and reinforce whole person education based on connections between school and home so that adolescents can ultimately suffer less damage from discrimination experiences.

이윤영 ( Youn-young Lee ) 한국특수체육학회 2021 한국특수체육학회지 Vol.29 No.4

이 연구는 사회생태모형에서 제시한 개인적 특성으로 사회경제적 요인, 심리적 요인, 환경적 특성을 단계적, 통합적으로 투입하여 장애인의 실제적인 생활체육 효과 증진을 위한 변인을 모색하는데 목적을 둔다. 이를 위해 2020 장애인 생활체육 실태조사 데이터를 활용하여 4,861명을 연구 대상으로 분석하였다. 사회경제적 변인으로 성별, 연령, 소득수준을, 신체에 대한 믿음, 인식과 관련한 개인의 심리적 변인으로 건강 상태 인식, 체력 상태 인식을, 사회적 환경 요인과 관련하여 운동 동반자 유무 및 전문지도자 경험 유무를 그리고 물리적 환경 요인과 관련하여 집 근처 체육시설의 인지 유무를 4단계에 걸쳐 위계적 회귀분석을 통해 살펴보았다. 분석 결과 사회경제적 특성과 심리적 요인, 사회적 환경 요인 및 물리적 환경 요인은 생활체육 효과와 유의미한 관계가 있는 변인으로 나타났으며, 생활체육 효과에 영향을 미치는 요인에 대한 위계적 회귀분석 결과 생활권 내 체육시설의 인지 여부가 가장 큰 영향력을 미치는 것으로 나타났고, 전문생활체육 지도자와의 강습 경험 여부, 체력에 대한 인식, 연령, 월평균 가구소득, 동반인 유무, 건강 상태 인식 변인도 통계적으로 유의미한 영향력을 보였다. This study tried to find variables for enhancing the practical effectiveness of sports for all participation with the disabled by individual socioeconomic factors, individual psychological factors, social environmental factors, and physical and environmental factors suggested by the social ecology model. For the purpose of this research, we used date collecting for 2020 National Sports for All Participation Survey for Individuals with Disabilities. Concretely, a total of 4,861 responses were analyzed at this survey for the hierarchical regression by using SPSS Program. As a result of the analysis, socioeconomic and psychological factors at the individual level were found to be variables related to the effect. Also it was found that social and environmental factors had a positively effective variables. According to the hierarchical regression analysis, it was found that awareness of sports facilities in the living area was the most influential factor related to the effects of sports for all participation. In conclusion, the results of the study showed that the effects of sports for all participation were influenced by personal demographic factors and psychological conditions, as well as professional sports leaders and perceptions of sports facilities.

이윤영(Lee, Youn-Young),서희정(Seo, Hee-Jung),최청락(Choi, Chong-Rak) 한국체육과학회 2012 한국체육과학회지 Vol.21 No.4

We tried to analyze the leisure actives in view of economic and education level on the purpose to find answers. For the analysis, this study used the date which was conducted by the National Statistical Office and the Ministry of culture, sports and tourism to look into the relationship between SES and Korean leisure activity in 2010. The title of date is Korean leisure activity survey and those two organizations were in charge of gathering date as directors. Researchers were allowed to use the raw date for this study by the Korea Social Science Data Archive also the approval number is A1-2010-0010. For this survey, interview and questionnaire methods based on the stratified multi-stage sampling after cluster sampling of the cities and counties were used. As a result, 3,051 people over 15 years old were selected for the final analysis. SPSSWINVer. 18.0 was used for frequencies and Chi-square test and the results were followed. First, the relationship between income and leisure time during week, leisure time during weekend and satisfaction of leisure time is negative. Second, statically significant differences were found in relationships between monthly average income and the purpose of leisure activity as well as education level and the purpose of leisure activity. Third, the education level represented as the negative relationship with the variables leisure time during week and satisfactions of leisure but it showed positive relationship with leisure time during weekend, leisure expense, general satisfaction of leisure’.
