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.

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. In this study, this characteristic was named ‘fashion recentness’. Third, it was possible to store or capture fashion brand-related images and texts. In this study, this characteristic was named ‘ease of storage of fashion data’. Fourth, fashion brand`s mobile SNS was useful in various ways to fashion consumers, so this characteristic was named ‘fashion usefulness’ in this study. The study extracted 10 sub-characteristics of the characteristics of fashion brand`s mobile SNS based on the results of a qualitative study.

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.

고교학점제에서의 영어 쓰기 수업 및 평가 : 문학작품과 디지털 미디어를 사용한 책임교육 대상 학생들에 대한 동기 부여
이유정(Yoo-Jung Lee),김보라(Bo La Kim) 한국실행연구학회 2024 교육실행연구 Vol.2 No.1
본 연구는 문학과 디지털 미디어를 활용한 영어 작문 수업이 고등학생, 특히 미이수 위험이 있는 책임교육 대상 학생(I등급)의 동기와 학업 성취도에 미치는 영향을 조사했다. 본 연구는 2022년 경기도 소재 일반 고등학생 1학년 17명을 대상으로 문학 기반 및 디지털 미디어 강화 영어 작문 수업을 운영하였다. 연구 결과는 다음과 같다: 첫째, 문학 참여는 학생들의 관심을 증가시켰고, 작문 수행평가에 대한 참여에 긍정적인 영향을 미쳤다. 둘째, 디지털 미디어의 사용은 문학 콘텐츠의 효율적인 전달을 촉진하여 전통적인 방법과 관련된 시간 제약과 이해의 어려움을 완화했다. 셋째, 디지털 미디어의 검색 기능은 학생의 수업 미참여 및 포기를 방지하고 학점 기반 고등학교 시스템에 중요한 최소한의 학업 성취도를 보장하는 데 중요한 역할을 했다. 특히, 단계적 작문 평가 과정은 남학생들 사이에서 동기 부여가 상당히 증가한 것으로 나타났으며, 이는 전통적인 일괄형 평가에 비해 그 효능이 있음을 시사한다. 본 연구는 교사의 고교학점제 영어 쓰기 교육 운영에서 학생의 참여를 증대시키고 책임 교육을 수행하는 데 도움이 될 것으로 기대한다. This study investigated the effects of integrating literature and digital media into English composition classes on the motivation and academic achievement of high school students, particularly those in responsibility education (Grade I) who are at risk of non-completion. The study was conducted with 17 first-year high school students in Gyeonggi Province in 2022, implementing literature-based and digitally enhanced English composition classes. The research findings are as follows: Firstly, literary participation increased student interest and positively impacted participation in composition performance assessments. Secondly, the use of digital media facilitated the efficient delivery of literary content, alleviating time constraints and comprehension difficulties associated with traditional methods. Thirdly, the search function of digital media prevented student non-participation and dropout, ensuring a minimum level of academic achievement in the credit-based high school system. In particular, the step-by-step composition evaluation process significantly increased motivation among male students, indicating its efficacy compared to traditional rote-style single assessments. This study is expected to assist in increasing student participation and implementing responsible education in high school credit system English writing education conducted by teachers.

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.
