The present study aimed to analyze the developmental trajectories of English achievement and exposure time through private education, utilizing univariate and multivariate latent growth curve analysis. This study used a subset of the Gyeonggi Education Panel Study data from 2012 to 2017. The results indicated consistent disparities in the growth of English achievement, depending on the student’s proficiency levels at the starting point. In particular, the early exposure to private tutoring was significantly and closely related to the initial status and the growth trajectory of English achievement. When the sample was classified by urbanicity, the findings suggested that the gap in English achievement was likely to increase over time across the two regions, with a stronger correlation with private tutoring found in urban areas. These results underscore the need for educational intervention for students in less advantageous conditions, and they provide valuable pedagogical implications for teaching English in the Korean EFL context.

본 연구는 제15차(2019) 청소년건강행태조사의 원시자료를 활용하여 생물-심리-사회 모델을 바탕으로 우리나라 청소년의 편의식품 섭취 경험의 영향요인을 파악하고자 하였다. 연구 결과 생물학적 요 인으로 성별, 학년, 아토피 피부염이 주요 요인으로 분석되었으며, 심리학적 요인으로는 스트레스 인지 수 준, 우울감 경험, 자살 생각 여부, 주관적 수면충족, 주관적 건강상태, 신체활동, 현재 흡연과 음주 경험이 영향요인으로 확인되었다. 또한 사회학적 요인으로는 영양 및 식이 교육, 아침식사 여부, 학업 성적, 주관 적 경제상태, 동거가족 여부가 청소년의 편의식품 섭취 경험에 영향을 미치는 것으로 나타났다. 이러한 결 과를 바탕으로 청소년의 건강한 식습관 관리를 위해서는 실효성 있는 영양 및 식이교육 프로그램 제공과 정서적 지지가 필요하며, 가족 구성원을 교육 대상에 포함시키는 등 다각적이고 체계적인 대책마련이 필요 하다.

This study aimed to investigate the relationship between eating speed and nutritional status among Korean high-school students using Nutrition Quotient for Korean Adolescents (NQ-A). In this study, a questionnaire survey was conducted in 453 high-school students (227 boys and 226 girls) from September 2019 to October 2019 in Chungbuk area. Based on the self-reported speed of eating data, subjects were classified into a fast group (n=180), a medium group (n=184), and a slow group (n=89). NQ-A scores for each group were measured in each speed group. In the environment section, girls showed a significant difference in usage time of electronic devices, such as TVs and smartphones: the fast group spent significantly more time than the medium group (p=0.035). In the practice section, among boys, the slow group had significantly higher scores for washing hands before eating than the medium and the fast groups (p=0.022). This study suggested that eating speed of high school students is associated with health-related environment factor and practice factor of NQ-A, such as time spent on smart devices or washing hands before eating. The study results can provide baseline data for nutrition education on health management of high school students.

목적 : 본 연구는 8~19세 아동 및 청소년의 가정, 학교, 지역사회, 공동체 생활에서의 참여를 측정할 수 있는 참여 평가도구인 The Child and Adolescent Scale of Participation(CASP)을 우리나라 문화에 적합하게 한국어로 번안하고, 타당도와 신뢰도를 검증하여 한글판 CASP를 개발하고자 하였다. 연구 방법 : 본 연구는 장애 22명 및 비장애 38명을 모집하였으며, 아동 및 청소년 총 60명을 대상으로 2018년 9월부터 2019년 1월까지 약 5개월간 진행되었다. 아동 및 청소년의 보호자를 대상으로 한글판 The Child and Adolescent Scale of Participation(CASP)을 자가 보고식 설문으로 진행하였다. 수집 된 자료는 Statistical Package for Social Science(SPSS) 통계분석 프로그램을 사용하여 타당도 및 신뢰도를 검증하였다. 결과 : 대상자의 일반적 특성에 대한 검증에서는 두 집단 간 유의한 차이를 보이지 않았으며, 장애 유무에 따른 집단 간 점수를 비교한 결과, 한글판 CASP의 타당도 검증에서 유의미한 차이가 발생하여 높은 판 별타당도가 검증되었으며, 신뢰도 검증에서는 높은 수준의 내적일치도와 검사-재검사 신뢰도를 확인하였다. 결론 : 한글판 CASP는 장애 유무에 상관없이 아동 및 청소년을 대상으로 참여를 평가할 수 있는 참여 평가도구이다. 본 연구를 통해 높은 수준의 타당도와 신뢰도가 확인되었다. 연구결과를 바탕으로 작업치료 임상 및 연구에서 장애 학령기 아동 및 청소년의 효과적인 참여 증진을 위한 치료 계획 수립의 기초자료로 활용되기를 기대한다.

The purpose of this study was to define Korean adolescent girls' brassiere size demand features in order to improve the suitability of junior brassieres for adolescent girls. The subjects for the data collection were Korean teenage girls from age 13 to 17 (n=492). Their body size was collected by conducting anthropometric measurement. The results of this study show that not only the growth of height, but also the growth of the body length is almost finished at the age of 15. The brassiere cup size, which shows the breast growth directly, increased remarkably at age 13 to 14, and once again at age 17. The demand for brassiere band size 70 appeared generally high among all ages. The research also suggests that the band size 60 and over 85 is also needed among the teenage girls. In matters of the brassiere cup size, junior brassieres over B-cup size are also necessary for teenage girls with big breasts to support their heavy breast weight. These results imply that the junior brassiere companies should improve their brassiere size range to fit the teenage girls' breasts properly.

This study was performed to investigate the hand size growth of Korean adolescents boys. Subjects were between 14 and 19 years (n=352). We collected the right hand size data of 19 measurements from each subject using 3D hand scanner. The total 26 hand measurements were analyzed including seven calculated measurements. Subjects were divided into three age groups (early, middle and late). Their hand size were compared. The results showed that all hand length measurements were significantly difference among age groups. Adolescent boys hands were sharply grown at age 16 years old. The hand dimensions of middle age group were compared with twenties men (n=215). There were significant differences between two groups. The middle age adolescents' hands were shorter and thicker than twenties men. Subjects were also divided by weight and height. Weight and height was closely related to hand size. The heavier and taller subjects had the thicker hand. Their fingers were longer than others. The adolescent boys and twenties men who were taller than the twenties' average height (173.4cm) were compared. Twenties men's hands were longer and thinner than that of adolescent boys. These results imply that the male adolescent hands grow short and thick in the adolescent period. Fingers continuously grow up as a long and thin shape after adolescent period.

The purpose of this study was to investigate the suitability of brassiere size and wearing habits of Korean adolescent girls. Subjects were 13 to 17 years old girls (n=282). The data was collected by anthropometric survey and qualitative questionnaire survey. Anthropometric survey measured bust and under bust girths; Qualitative questionnaire survey focused on the practice of purchasing and wearing of brassiere. Two general conclusions emerged: 1) Majority of Korean adolescent girls wore a smaller sized cup than their breast volume 2) Korean adolescent girls wore a larger sized band. These results show the need of educating Korean adolescent girls for their appropriate brassiere size and fit. The value of the brassiere that Korean adolescent girls place differed by age. While the younger adolescent girls expected their brassiere to prevent showing the breast vibration, the older adolescent girls expected their brassiere to avoid breast sagging. The older aged adolescents more valued the fit and style of the brassiere compared to the younger aged group when they purchase brassiere. The younger adolescent girls were more likely to be dissatisfied with the fit of the cup. These results reveal that the junior brassiere should be designed to fit adolescent girls' breast shape and size.
