The purpose of this study is to examine the mediating effect of physical activity in the relationship between generalized anxiety disorder and overdependence on smartphones in adolescents. To find a way for solving the problems caused by the over-use of smartphones during adolescence, we tried to find the importance of a health promotion program through physical activities. For the purpose of the study, the 2020 Youth Health Behavior Survey data conducted by the Ministry of Education, the Ministry of Health and Welfare, and the Korea Centers for Disease Control and Prevention were used as analysis data for this study. As a result of the study, firstly, generalized anxiety disorder has a negative (-) relationship with physical activity, and physical activity also has a negative (-) relationship with overdependence on smartphones. Secondly, as a result of analyzing the mediating effect of physical activity in the relationship between generalized anxiety disorder and smartphone overdependence experience, the physical activity was found to be a significant factor. Thirdly, it was confirmed that the physical activity has a partial mediating effect in the relationship between generalized anxiety disorder and smartphone overdependence experience. Increasing physical activity through team sports rather than individual sports may help reduce smartphone use. 이 연구는 청소년들의 범불안장애와 스마트폰 과의존의 관계에서 신체활동의 매개효과를 확인하는데 목적을 둔다. 청소년 시기 스마트폰 이용으로 인한 문제점을 해결하기 위한 방안으로 신체활동을 통한 청소년의 건강증진 프로그램의 필요성을 찾고자 하였다. 연구 목적을 위하여 교육부·보건복지부·질병관리청에서 공동으로 실시한 2020년 청소년건강행태조사자료를 이 연구의 분석자료로 활용하였으며, SPSS 23.0을 이용하여 요인분석, 신뢰도분석, 빈도분석, 다중회귀분석 그리고 3단계 매개효과 분석을 실시하여 검증을 시도하였다. 연구결과 첫째, 범불안장애는 신체활동과 부적(-)인 관계가 있고 신체활동 역시 스마트폰 과의존과 부적(-)인 관계가 있는 것으로 나타났다. 둘째, 범불안장애와 스마트폰 과의존 경험 관계에서 신체활동의 매개효과를 분석한 결과 신체활동은 유의미한 매개변수인 것으로 나타났다. 셋째, 신체활동은 범불안장애와 스마트폰 과의존 경험의 관계에서 부분매개효과가 있다는 것을 확인하였다. 개인 스포츠활동보다는 팀스포츠활동을 통해 신체활동을 높이는 것은 스마트폰사용을 줄이는데 도움이 될 수 있다.

Purpose:The aim of the study was to investigate postnatal changes in growth and insulin, leptin, IGF-I, adiponectin, and ghrelin, and to examine the relationship of these hormones with catch-up growth in full-term small for gestational age (SGA) infants. Methods: SGA was defined as a birth weight less than the ten percentile. Weight and height were measured at birth, 1 month, 6 months, 1 year, and 2 years of age in 70 SGA infants (40 females and 30 males). The infants were subdivided according to their weight and height catch-up growth (CUG) at 2 years old. CUG is defined as reaching a standard deviation score (SDS) of ˃ -2 SDS. Blood samples were serially taken for insulin, leptin, insulin- like growth factor (IGF)-I, adiponectin, and ghrelin. Results: 1) Dramatic CUG for weight and height occurred during the first year of life; weight and height growth gain decreased thereafter. 2) Non-catch-up growth (NCUG) infants showed more decreased weight and height growth gain than CUG infants between the first and second year of life. 3) Weight CUG was 77.1% and height CUG was 75.8% in the SGA infants. 4) Weight CUG infants showed significantly higher leptin and ghrelin levels than in weight NCUG infants at the age of 1 year (P ˂0.05). 5) Height CUG infants showed significantly higher leptin and ghrelin levels than in height NCUG infants at the age of 1 year (P ˂0.05). Conclusion: CUG for weight and height occurred during the first year of life and growth velocity decreased thereafter. Significant corresponding changes occurred with regard to serum leptin and ghrelin.(J Korean Soc Pediatr Endocrinol 2011;16:112-118)

이윤영,정이상 한국경영학회 2014 한국경영학회 통합학술발표논문집 Vol.2014 No.8

대학의 연구비 지원관련 투명성과 효율성에 대해 연구비 지원기관들은 많은 의구심을 제기하고 있다. 연구비를 합리적이고 투명하게 관리해야 할 책임은 정부와 대학 모두에게 있으며 연구개발 활동에 대한 책임 즉 accountability의 중요성이 가중되고 있다. 최근 대학들은 연구비의 투명성 제고를 위해 연구비중앙관리제도를 도입하여 중앙 집중관리를 하고 있으며 연구지원시스템을 개발하여 운영하고 있다. 대부분의 산학협력단은 이와 별개로 결산관리, 세무신고를 위해 ERP패키지를 도입하여 사용하고 있다. 하지만 산학협력단은 연구지원시스템과 ERP 패키지의 Heterogenous 이원화(Duality)된 시스템을 운영함으로써 이중입력(Dual-Booking) 문제가 발생하여 시간과 비용의 추가 발생, 부정확한 회계정보를 외부정보이용자에게 제공 할 가능성을 야기 하고 있다. 이원화 시스템 운영 이유는 예산문제이다. 많은 대학에서 ERP도입을 추진하고 있으나 막대한 자금 부담과 성공에 대한 의구심으로 적극적인 도입을 못하고 있으며 대학의 ERP 도입 성공요인에 대한 연구가 활발하게 이루어지고 있다. 본 연구의 목적은 Heterogenous 이원화 문제 해결 방안으로 동기화(Synchronization)방식을 제안하고자 한다. 본 연구의 대상은 연구지원시스템을 운영하면서 ERP패키지를 별도 운영 중인 산학협력단으로 한정하여 신뢰성을 높였다. 연구 방법은 선행연구를 통해 문제점을 파악하고 동기화를 통해 문제점을 해결한 사례 연구를 제시하여 선행연구와 사례연구를 업무프로세스측면과 시스템측면으로 비교 분석하였다. 선행연구에서 제시한 문제점을 개별항목으로 구분하고 어떤 업무에서 발생하는지를 파악하여 사례연구와 비교 분석함으로써 Heterogenous 시스템의 동기화를 통해 이중입력, 부정확한 회계정보 문제를 해결하였다.

The emission of particulate matter and volatile organic compounds (VOCs) from a motor vehicle painting booth was quantitatively evaluated. Most particulate matter was emitted during the spraying process, in which the PM10 concentration was 16.5 times higher than that of the drying process. When the paint was being sprayed, the particles with a diameter of 1.0~2.5 μm accounted for 39.4% and particles greater than 2.5 μm in diameter accounted for 30.6% of total particles. On the other hand, small particles less than 0.5 μm in diameter accounted for 52.4% of total particles during the drying process. In contrast to the particulate matter, high concentrations of VOCs were emitted during both spraying and drying processes. Butyl acetate, xylene, toluene, and m-ethyltoluene were the most abundant VOCs emitted from the motor vehicle painting booth. Additionally, xylene, butyl acetate, toluene, and 1,2,3-trimethylbenzene were the dominant ozone precursors. Especially, xylene exhibited the highest ozone production contribution (32.5~44.4%) among 34 species of the ozone precursors. The information obtained in this study can be used to establish a suitable management strategy for air pollutants from motor vehicle painting booths.

Therapeutic potential of a phospholipase D1 inhibitory peptide fused with a cell-penetrating peptide as a novel anti-asthmatic drug in a Der f 2-induced airway inflammation model

이윤영,이소영,박신영,최혜진,김응국,한중수 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-

Asthma is a chronic lung disease that causes airflow obstruction due to airway inflammation. However, its therapeutics remain inadequate. We previously reported that phospholipase D1 (PLD1) is a key enzyme involved in the production of pro-inflammatory cytokines in airway inflammation induced by the house dust mite allergen Dermatophagoides farinae 2 (Der f 2). We also revealed that PLD1 is specifically inactivated by AP180 (assembly protein, 180 kDa) and identified the PLD1-specific binding motif (TVTSP) of AP180. Therefore, the aims of this study were to develop a novel anti-asthmatic agent that could suppress airway inflammation by inhibiting PLD1 and examine its acute and chronic toxicity. We designed TAT-TVTSP, a PLD1-inhibitory peptide fused with a cell-penetrating peptide (CPP) delivery system. TAT-TVTSP was efficiently delivered to bronchial epithelial cells and significantly reduced Der f 2-induced PLD activation and Interleukin 13 (IL-13) production. Intranasally administered TAT-TVTSP was also efficiently transferred to airway tissues and ameliorated airway inflammation in a Der f 2-induced allergic asthma mouse model. Moreover, we investigated the safety of TAT-TVTSP as a therapeutic agent through single- and repeated-dose toxicity studies in a mouse model. Taken together, these results indicated that a PLD1-inhibitory peptide fused with a cell-penetrating peptide may be useful for treating allergic inflammatory asthma induced by house dust mites (HDMs).

다문화 청소년의 학교 폭력 피해 경험이 문화적응스트레스에 미치는 영향: 사회적지지의 조절효과를 중심으로

이윤영 대한범죄학회 2019 한국범죄학 Vol.13 No.1

The purpose of this study was to examine the relationship between school bullying and acculturation stress experienced by multicultural adolescents and their social support as a moderator. For this purpose, this study analyzed the Multi cultural Adolescent Panel Study data nationally collected by National Youth Policy Institute in 2015. The results from the hierarchical analysis were as follows. First, school bullying was significantly related to the acculturation stress, the higher the levels of bullying, the higher their levels of acculturation stress. Second, social support, including parents, teachers and friends’ support was not found to moderate the relationship between bullying and acculturation stress. Third, parents and teachers’ support except friends among social support were found to moderated the relationship between bullying and acculturation stress. This results showed that when multicultural adolescents are victimized from bullying as school violence, high parents or teachers’ support is buffering acculturation stress. Based on this results, policy implications were suggested. 본 연구의 목적은 다문화 청소년의 집단 괴롭힘 피해 경험이 문화적응스트레스에 미치는 영향에서 사회적지지의 조절효과를 살펴보는 것이다. 이를 위하여 한국청소년정책연구원의 다문화패널(MAPS) 5차년도 데이터를 활용하여 위계적 회귀분석 등을 실시하였다. 분석 결과는 다음과 같다. 첫째, 다문화 청소년의 집단 괴롭힘 피해 경험은 문화적응스트레스의 하위 영역인 한국사회 적응과정상의 스트레스와 차별 스트레스에 모두 유의미한 영향을 미치는 것으로 나타났다. 즉 집단괴롭힘 피해를 많이 당할수록 적응과정상의 스트레스 수준과 차별스트레스 수준이 높다는 결과를제시할 수 있다. 둘째, 다문화 청소년의 집단 괴롭힘 피해와 적응과정상의 스트레스 관계에서 사회적지지의 하위 영역인 부모, 교사, 친구지지의 조절효과를 살펴본 결과 상호작용변인의 조절효과는나타나지 않았다. 셋째, 집단 괴롭힘 피해가 차별스트레스에 미치는 영향에서 사회적지지의 조절효과를 살펴본 결과, 친구지지를 제외한 부모지지와 교사지지의 상호작용항은 집단 괴롭힘 피해와 차별스트레스의 관계를 부(-)적으로 조절하는 완화효과가 있는 것으로 나타났다. 이 연구는 대표적인 학교폭력 문제인 집단괴롭힘 피해와 다문화 청소년의 한국사회 적응, 사회적 관계 등 관련 요인의 경로를 밝혔다는 점에 의의가 있으며 사회적지지를 통해 문화적응스트레스를 완화할 수 있는 정책적 방안을 제언하고자 하였다.
