성지선,이정권,노혜미,박용순,안은주 대한가정의학회 2013 Korean Journal of Family Medicine Vol.34 No.2
Background: The number of internet users is increasing rapidly and internet addiction among adolescents has become a serious public health problem in Korea. In the light of behavioral addiction, this study was aimed to identify the associations between the risk of internet addiction and other problem behaviors which can lead to addiction, such as cigarette smoking, alcohol drinking, drug abuse, and sexual intercourse among a nationally representative sample of Korean adolescents. Methods: Data from the 2010 Korean Youth Risk Behavior Web-based Survey (respondents, 73,238) were analyzed. Risk of internet addiction was assessed by the ‘Korean Internet Addiction Proneness Scale for Youth-Short Form: Self Report’which was developed by the Korean National Information Society Agency in 2008. Multiple logistic regression analysis was used to calculate the odds ratios of problem behaviors among adolescents at high risk for internet addiction and adolescents at low risk for internet addiction. Results: The odds of smoking experience, drug abuse experience, and sexual intercourse experience were significantly higher among boys at high risk for internet addiction compared to boys at low risk for internet addiction. Among girls at high risk of internet addiction, the odds of smoking experience, drinking experience, and drug abuse experience were significantly higher compared with girls at low risk of internet addiction. Conclusion: The risk of internet addiction was associated with cigarette smoking, alcohol drinking, drug abuse, and sexual intercourse experience among Korean adolescents.
체험형 퍼포먼스 <어둠 속의 대화>를 통한 교육적 함의 : 다중지능이론을 중심으로
성지선 한국문화융합학회 2021 문화와 융합 Vol.43 No.3
본 연구는 체험형 퍼포먼스 <어둠 속의 대화>를 하워드 가드너의 다중지능이론을 통해 분석하였다. 다중지능은 언어지능, 논리수학지능, 공간지능, 신체운동지능, 음악지능, 대인관계지능, 자기이해지능, 자연탐구지능, 실존지능 등 총 9개의 유형으로 구성돼 있다. 이들 유형 중, <어둠속의 대화>는 6개에 직접적 영향을 받는 것으로 나타났으며 나머지 3개 역시 간접적 영향을 받는것으로 보인다. 따라서 전인적 교육이 필요한 시기의 청소년들을 대상으로 교육적 효과가 매우크다는 점을 알 수 있다. 이러한 결과를 토대로 <어둠 속의 대화>처럼 체험형 형식의 청소년 대상공교육 프로그램을 제안하였으며 크게는 직업체험, 예술체험, 장애체험 등 3개의 관점별로 나누어 예상 시사점을 살펴보았다. 제안 프로그램은 공교육에 접목할 수 있는 사회적 주제가 있어야하며, 청소년들이 다양한 주제의 퍼포먼스 중에서 선택할 수 있도록 하며 소규모로 진행될 필요가있다.

Objectives: The aim of this retrospective cohort study was to investigate whether non-alcoholic fatty liver disease (NAFLD) was associated with incident bone mineral density (BMD) decrease. Methods: This study included 4536 subjects with normal BMD at baseline. NAFLD was defined as the presence of fatty liver on abdominal ultrasonography without significant alcohol consumption or other causes. Decreased BMD was defined as a diagnosis of osteopenia, osteoporosis, or BMD below the expected range for the patient’s age based on dual-energy X-ray absorptiometry. Cox proportional hazards models were used to estimate the hazard ratio of incident BMD decrease in subjects with or without NAFLD. Subgroup analyses were conducted according to the relevant factors. Results: Across 13 354 person-years of total follow-up, decreased BMD was observed in 606 subjects, corresponding to an incidence of 45.4 cases per 1000 person-years (median follow-up duration, 2.1 years). In the model adjusted for age and sex, the hazard ratio was 0.65 (95% confidence interval, 0.51 to 0.82), and statistical significance disappeared after adjustment for body mass index (BMI) and cardiometabolic factors. In the subgroup analyses, NAFLD was associated with a lower risk of incident BMD decrease in females even after adjustment for confounders. The direction of the effect of NAFLD on the risk of BMD decrease changed depending on BMI category and body fat percentage, although the impact was statistically insignificant. Conclusions: NAFLD had a significant protective effect on BMD in females. However, the effects may vary depending on BMI category or body fat percentage.
발레 전공 대학생이 인지한 교수 감성지능이 자기효능감, 학습만족, 학업지속의도에 끼치는 영향 연구

This study, the effect of emotional intelligence education perceived by the ballet major on self-efficacy, learning satisfaction, and academic persistence of college students was analyzed. A total of 235 respondents were analyzed through exploratory factor analysis and confirmatory factor analysis. As a result, out of a total of 15 hypotheses, 8 were rejected and the remaining 7 were adopted. In this interpretation, for students, the emotional intelligence factor of the professor had a partial influence on the educational aspect. In particular, it is speculated that students appreciate the professor’s ability to understand and control their emotions.
이머시브 공연의 장소성과 상호작용성 분석 : <안산순례길>을 중심으로

본 연구는 이머시브 공연 <안산순례길>을 장소성과 상호작용성 중심으로 분석하였다. 장소성에서는 세월호 희생자의 생활공간과 거리를 걸으며 답습했다는 점, 이를 통해 참여자가 공연의 주인공이 되도록 전이체험을 유도했다는 점을 분석하였다. 상호작용성에서는 참여자가 다양한 참여 형식을 수행할 수 있게 하였고, 이를 통해 부채의식을 덜거나 치유효과를 발휘했다는 점을 분석하였다. 또한 세월호 이야기보다 도시 안산에 집중하여 연대와 공감을 추구했다는 점도 확인하였다. 이를 통해 <안산순례길>은 사회적으로 순기능이 많고 예술 형식이 다채로우며 다른 이머시브 공연들과도 차별성이 있어 지속적인 개최 및 후속 연구를 고려할 필요가 있음을 살펴보았다. This study analyzed the placement and interactivity of the immersive performance < Ansan Pilgrimage Road >. In the sense of place, it was analyzed that first, walked and followed the living spaces and streets of the victims of the Sewol ferry, and second, through this, the participants induce a transfer experience to become the main character of the performance. In terms of interactivity, participants were able to carry out various forms of participation, and as a result, they analyzed that they had relieved debt consciousness or exerted healing effects. In addition, it was confirmed that they pursued solidarity and sympathy by focusing more on the city 'Ansan' rather than the story of the Sewol ferry. Through these results, it can be seen that < Ansan Pilgrimage Road > has many social functions, a variety of art forms, and is differentiated from other immersive performances. So, it is necessary to consider the continuous holding.

A high proportion of hazardous (PVC, asbestos, chlorinated solvents) and infection wastes are treated in incinerators, the high temperature and high energy characteristics of plasma may be employed to convert waste materials into inert small volume products and combustible gases, plasma torch melting(PTM) is one of the most widely used tool for the vitrification of wastes. The ash product generated is of low bulk density and may also contain leachable quantities of toxic heavy metal and organic species. Plasma processing is able to treat these ashes, destroying any contained polyaromatic hydrocarbons components. Also we presented a steady three-dimensional model for a plasma melting furnace optimum designed in this study with RNG k-ε model, and its use in characterizing the structure of the flow field, temperature field and reaction field. Among various types of plasma torches, non-transferred hollow cathode type torch is best suited due to its long lifetime, easy power controllability and steady power output. Development of a plasma torch showed the lifetime longer than 300 hours and efficiency better than 65% And the various factors(electrode diameter, cooling flow rate and temperature and gas flow rate affecting the thermal efficiency of the torch) were experimentally evaluated.
