본 연구의 목적은 청소년들의 스마트폰 과의존과 피로회복 간의 관계에서 불안의 매개효과를 검증하여, 청소년의 스마트폰 과의존 중재의 근거자료를 확보하는 것이다. 연구 대상자는 ‘제16차 청소년 건강행태 온라인조사’를 이용한 청소년 54,948명이다. 연구변수 간의 관계는 상관분석, 요인분석, 매개효과 분석을 실시하였다. 연구 결과 청소년의 스마트폰 과의존은 피로회복에 영향을 미치는 직접효과와, 불안을 경유하여 피로회복에 영향을 주는 간접효과가 나타났다. 청소년의 스마트폰 과의존이 매개변인인 불안에 유의한 영향을 주었고, 피로회복에 유의한 영향을 주었다. 또한 또한 불안은 스마트폰 과의존과 피로회복 간의 관계에서 매개효과가 있는 것으로 확인되었다. 따라서 스마트폰 과의존 청소년을 대상으로 피로회복 을 향상하기 위해 불안을 관리할 필요가 있다.

The purpose of study was to examine the factors influencing fast food consumption in Korean adolescents. The analysis was conducted using cross sectional study data from the 16th Korea Youth Risk Behavior Web-based Survey in 2020. A total 54,948 middle and high school students participated in this study. The subjects in the analysis were 28,353 males and 26,595 females, 28,961 middle school and 25,987 high school students. In total, 56.6% Korean adolescents consumed fast food once or twice weekly and 25.4% consumed fast food more than three times weekly. Logistic regression analysis revealed that fast food consumption was significantly associated with dietary behavior such as lower breakfast intake (OR: 0.930, 95%CI: 0.891~0.970, p<0.001), higher soda drinks consumption (OR: 2.563, 95%CI: 2.452~2.678, p<0.001), and higher sweet drinks consumption (OR: 1.898, 95%CI: 1.818~1.982, p<0.001). For psychological and health behavior factors, fast food consumption was also significantly associated with higher perceived stress (OR: 1.239, 95%CI: 1.163-1.321, p<0.001), higher smoking (OR: 1.300, 95%CI: 1.164~1.453, p<0.001), higher drinking (OR: 1.193, 95%CI: 1.112~1.280, p<0.001), higher depression experience, higher loneliness experience, and lower subjective health, In conclusion, fast food consumption in Korean adolescents was associated with undesirable dietary habits and psychological and health behavior, suggesting that appropriate education programs are necessary to reduce such behavior.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16, 574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

지질조사는 제7차 지구과학교육과정에서 지구과학을 배우는 학생에게 매우 중요하지만, 시간, 거리, 비용이 너무 많이 들어 실제로 학생들이 야외지질조사를 나가서 학습하기 어려운 경우가 많다. 이러한 어려운 문제를 해결하기 위하여 이 연구는 제주도 송악산과 지삿개 일대를 선정하여 가상야외지질조사의 웹 컨텐츠와 교수-학습 자료를 개발하고자한다. 개발된 웹 컨텐츠는 주 메뉴, 부메뉴, 내용의 3 부분으로 구분하여 학습자가 쉽게 인식하도록 구성하였다. 기존웹 자료의 한계를 극복하기 위하여 동영상과 탐구 학습지를 학습자에게 제공하였고 웹 컨텐츠는 실제 야외지질조사에서 얻을 수 있는 내용을 체험할 수 있도록 고안하였다.
