Objectives : The aim of this study is to investigate the association between obesity indices(body mass index, weight, waist-hip ratio and waist circumference) in adolescents and the carotid intima-media thickness (C-IMT) in early adulthood. We also wanted to identify the best predictor for C-IMT among these obesity indices. Methods : This study used community-based prospective cohort study, known as the Kangwha Study, and the data we used were from subjects who were 16-years old in 1996 (defined as "adolescence") and 25 years-old in 2005 (defined as "early adulthood"). The 256 subjects (113 men and 143 women) who were used for analysis participated in both follow-ups, and they underwent B-mode ultrasonography of the carotid arteries at the early adulthood follow-up. Obesity indices were defined as the body mass index, weight, waist-hip ratio and waist circumference. The C-IMT was defined as the mean of the maximal IMT of each common carotid artery. The C-IMT and obesity indices associations were evaluated via multivariable regression, logistic regression and the receiver-operator characteristic curve analyses. Results : In men, all the obesity indices in adolescence were showed to have statistically significant positive association with C-IMT in early adulthood. However, no such relationship was showed in women. On multiple regression and logistic regression analysis, the waist-hip ratio showed the biggest relationship with the C-IMT among the 4 obesity indices. However, there were no statistical significant differences and no best predictor was found. For the women, the obesity incidences and C-IMT showed no relationships. Conclusions : This study suggested that obesity in adolescence was related to an increase C-IMT in healthy young Korean men.

이유정(Yoo-Jung Lee),오성배(Sung-Bae Oh) 중앙대학교 한국교육문제연구소 2016 한국교육문제연구 Vol.34 No.1

이 연구는 학업성취도 격차의 주요한 원인으로 지적되어 온 거주 지역에 주목하여, 거주 지역에 따라 학생들의 학업성취도에 차이가 있는지 확인한다. 그리고 지역과 개인의 사회경제적 지위와 독립적으로 사회적 자본이 학업성취도에 영향을 미치는지 분석하여 학업성취도 격차를 완화할 수 있는 기제로서 작동할 수 있는지 검증하는 데 그 목적이 있다. 이러한 연구 목적을 달성하기 위하여 한국교육종단연구(KELS) 3차년도(2007) 조사에 참가한 중학교 3학년 학생 및 부모 4,894명의 자료를 분석하였다. 분석 결과에 따르면, 거주 지역에 따라 학업성취도에 유의미한 차이가 있는 것으로 확인되었다. 그리고 가정내 사회적 자본(한부모 가정 여부, 부모의 교육기대수준, 부모의 학습지원활동)은 거주 지역, 학생의 사회경제적 지위, 사교육 시간과 비용, 부모의 문화적 자본, 교우관계와 독립적으로 학업성취도에 영향을 미치며, 이 점은 지역 간 학업성취도 격차를 줄일 수 있는 기제로서 가정내 사회적 자본의 가능성을 보여준다. In this study focused on residential areas that have been pointed out as the main cause of the academic achievement gap, verify there is a difference in academic achievement depending residential areas. Also, analyzing the social capital in family affect academic achievement gaps independently from the other variables. Through this, the paper aims to verify whether social capital in family can operate as a mechanism to narrow academic achievement gaps among regions. In order to achieve the purpose of these studies, to analyze dataset of the 3rd year surveys of the Korean Education Longitudinal Study 2005(KELS 2005). According to the analysis results, it has been found that differences exist in academic achievement according to the place of residence. Social capital in family affect academic achievement independently from the place of residence, students’ socio-economic status, time and cost for private education, parents’ cultural capital, and peer relationship. This study’s results show the possibility that social capital in family operates as a mechanism to narrow academic achievement gaps.

This study was an experimental qualitative study on the characteristics of fashion brand`s mobile SNS. The study was focused on mobile Facebook and identified the characteristics of fashion brand`s mobile SNS. In-depth interviews were conducted with 10 people in the 20s, who have used fashion brand`s mobile Facebook application and currently live in Seoul or Gyeonggi province. After analysis of the in-depth interview data, four characteristics of fashion brand`s mobile SNS were identified as follows. First, it was possible to access fashion brand`s mobile SNS at any time anywhere, if users needed brand-related information. In this study, this characteristic was named ‘fashion accessibility’. Second, it was possible to access update-information using fashion brand`s mobile SNS or get up-to-date information about the brand in real-time.

망조정을 위한 GPS 소프트웨어 개발

이유정(Yoo Jung Lee),최윤수(Yun-Soo Choi),홍창기(Chang-Ki Hong) 대한공간정보학회 2009 한국공간정보학회 학술대회 Vol.2009 No.4

우리나라의 3차원 위치결정은 주로 GPS 관측자료를 이용하여 수행되고 있으며, GPS 자료처리 및 성과산출은 외국에서 개발된 상업용 또는 학술용 소프트웨어인 GPSurvey, TGO, LGO, Bernese 등을 이용하여 결과를 산출하고 있다. 하지만 각각의 소프트웨어는 데이터 처리 알고리즘이 다르기 때문에 성과산출 결과가 서로 상이하며, 자료처리 절차가 표준화 되어 있지 않기 때문에 독자적인 국내 GPS 망조정 소프트웨어 개발이 제기되고 있다. 본 연구에서는 현재 개발 중인 망조정 소프트웨어를 통해 산출된 예비결과를 분석하였다. 분석결과 산출결과와 고시좌표간의 3차원 오차크기는 평균 3cm 정도로 나타났다. 이 결과는 현재의 상용 프로그램과 비교하면 정확도가 다소 떨어지지만 현 상황에서 고려되지 않은 오차들을 고려할 경우 정확도가 향상될 것으로 기대된다.
