본 연구의 목적은 중학생의 또래애착이 자존감과 내재적 학습 동기 사이에서 매개효과가 있는지를 확인하는 것이다. 이를 위해 본 연구에서는 전라남도 S시 소재의 남녀 중학생 457명(남학생 225명, 여학생 232명)을 대상으로 자존감, 또래애착, 내재적 학습동기의 수준을 측정하여 자료를 수집하였다. 연구결과는 다음과 같다. 중학생의 자존감과 또래애착, 내재적 학습동기 사이의 상관은 모두 유의하게 나타났다. 자존감은 또래애착과 내재적 학습동기에 유의한 영향을 주었으며, 또래애착도 내재적 학습동기에 유의한 영향을 주었다. 한편 또래애착은 자존감과 내재적 학습동기 사이에서 부분매개효과가 있는 것으로 나타났다. 또래애착의 매개효과는 학년에 따른 다른 양상을 보였다. 본 연구를 통해서 중학생들의 자존감은 또래애착에 영향을 주며, 자존감의 영향을 받은 또래애착은 내재적 학습동기에 영향을 줄 수 있음을 확인하였다. 또한 본 연구의 시사점과 제한점에 대하여 논의하였다.

The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).

This study investigates the effect of adolescent dining habits on their physical development. We selected 200 students from the three high schools in Taejon, and surveyed with a questionnaire and collected data concerning physique from school health records. The results obtained from this study were as follows: 1. A point of intersection of two development trends of male and female students' heights was between sixth grade of elementary school and first grade of middle school. Two development trends of weights didn't have a point of intersection and male students' development trend of weights was a little higher than that of female students. 2. There were significant differences in the weight and BMI of male students. The 'regular dining' group had heavier weight and higher BMI than the other group, and the 'Eating only favorite food' group had lower weight and BMI than the other group. In female, heights of 'three meals a day' group were higher than that of 'two meals a day' group and the more snacks per day, the higher students' height was. 3. The 'regular exercise' group had significantly heavier weight and higher BMI than the other group amount females. 4. 'Regular dining' and 'Eating habits' had a positive linear relationship with male students' weight and BMI. 'Number of times of snacking' has a positive linear relationships with female students' height and a negative linear relationship with female students' BMI. Since dining habits of adolescents have not only an effect on their development but also later adults' health, to develop good habits of health and dining is a critical issue.

이 연구의 목적은 인공지능 윤리의식에 대한 초등학교, 중학교, 고등학교 학생들의 성차를 분석하는 것이다. 과연 인공지능 윤리의식에 성차가 존재하는지, 존재한다면 언제부터 성차가 발생하는지를 알아보기 위한 연구이다. 본 연구는 I 광역시 초등학생 198명(여학생 98명, 남학생 100명), 중학생 265명(여학생 166명, 남학생 99명), 고등학생 114명(여학생 58명, 남학생 56명)을 대상으로 실시하였다. 본 연구 결과는 다음과 같다. 첫째, 전체 남학생과 여학생 사이의 인공지능 윤리의식의 성차가 확인되었다. 둘째, 인공지능 윤리의식의 성차는 초등학교에서 중학교, 고등학교로 학령이 높아질수록 확고해지는 경향이 있었다. 셋째, 초등학생, 중학생, 고등학생 모든 단계에서 여학생은 아직 인공지능에 대한 신뢰성이 그리 높지 않고, 차별 금지에 대한 우려가 남학생에 비해 크며, 예술 등의 분야에서 인공지능의 인간 영역에의 진입 허용에 대해 부정적인 입장을 가지고 있는 것으로 파악되었다. 넷째, 학령과 성별의 상호 작용 효과는 안정성 및 신뢰성, 그리고 허용과 한계 범주에서 확인되었다. 이러한 결과들을 종합해 볼 때, 인공지능 교육 활동시 인공지능 윤리의식에 성차가 생기지 않도록 교육 프로그램을 양성 평등적으로 접근하는 교육적 방안이 필요하다고 할 수 있다.

The most frequently chosen combination of foods for number of two choices was beefburger and cola. The mean average energy intake from fast foods for one meal was 620.7 kcal for male, 504.5 kcal for female. The energy ratio of carbohydrate : protein fat from fast foods was 49 : 14 : 43, which means fat intake is much higher than recommended level ($20\%$). Fiber was appeared to be the lowest on the nutrient density which was $17.7\%$ of the recommended level for Koreans, vitamin C was next ($22.8\%$ for male, $20.1\%$ for female). In mineral, iron was the lowest ($71.8\%$ for male, $67.1\%$ for female), and protein was over $100\%$ for both males and females. Frequency of fast food intake was positively correlated with eating frequency of the salty, the sweets, him, caffeine containing foods, instant noodles, and cookies. In conclusion, frequent consumption of fast foods can lead unbalanced nutrient intakes for middle school students, and those who consumed fast foods frequently showed undesirable food habits in their daily meal.
