본 연구는 광주지역에 거주하는 중학생을 대상으로 김치에 대한 인식과 섭취실태에 대해 조사하고 김치 인식도에 따른 김치 섭취의 차이를 분석하여, 학생 스스로 김치에 대해 재인식 할 수 있도록 하고, 학생들의 올바른 식습관 형성에 도움을 주는 기초 자료를 제공하고자 하였다. 광주지역에 거주하는 중학생을 대상으로 구조화된 설문지로 자료를 수집하였고, 374부를 최종 분석에 사용하였다. 중학생의 김치 인식도는 1학년은 4.10점, 3학년은 3.92점으로 1학년이 3학년보다 김치에 대한 인식이 높았다(p<0.001). 중학생의 김치 기호도는 '김치를 좋아하는 정도'(p<0.001), '김치를 먹지 않는 이유'(p<0.05)에서 1학년과 3학년이 유의한 차이가 나타났다. '김치를 좋아하는 정도'에서 김치를 좋아하는 학생은 1학년이 81.7%, 3학년이 59.8%로 1학년이 김치를 더 좋아함을 알 수 있었다(p<0.001). 중학생의 김치 섭취 실태는 '김치 섭취 횟수'(p<0.05), '한번에 섭취하는 김치 양'(p<0.05) 항목에서 1학년과 3학년이 유의한 차이가 나타났다. 김치 섭취 횟수는 1학년은 하루에 한번 집에서 섭취하는 비율이 높았고, 3학년은 하루 3회 이상 섭취하는 비율이 높았다(p<0.05). 중학생의 김치 교육은 '김치 권유에 대한 나의 태도'(p<0.05), '김치 섭취 교육의 필요성'(p<0.05), '김치 정보를 듣고 좋은 음식이라고 생각한 적의 여부'(p<0.001), '희망하는 김치 교육 방법'(p<0.001), '김치 섭취를 높이기 위한 방법'(p<0.05)에서 1학년과 3학년이 유의한 차이가 나타났다. 중학생의 김치 인식도에 따른 김치 기호도는 '김치를 좋아하는 정도'(p<0.001), '김치를 좋아하는 이유'(p<0.05), '김치를 싫어하는 이유'(p<0.05)에서 김치 인식도에 따라 유의한 차이가 나타났다. 즉, 김치 인식도가 높을수록 기호도가 높은 경향을 보였고, 김치 특유의 맛을 좋아하였다. 김치 인식도에 따른 김치 섭취 실태는 '김치 섭취 횟수'(p<0.001), '한번에 섭취하는 김치 양'(p<0.05)에서 김치 인식도에 따라 유의한 차이가 나타났다. 즉, 김치 인식도가 높을수록 김치 섭취 횟수와 섭취량도 더 많은 경향을 보였다. 김치 인식도에 따른 김치 교육은 '김치 권유에 대한 나의 태도'(p<0.05), '김치를 담근 경험'(p<0.05), '김치 섭취 교육의 필요성'(p<0.001), '김치 정보를 듣고 좋은 음식이라고 생각한 적의 여부'(p<0.001)에서 김치 인식도에 따라 유의한 차이가 나타났다. 즉, 김치 인식도가 높을수록 김치를 권했을 때의 태도 변화가 긍정적이었고, 김치를 담근 경험이 있는 학생일수록 인식도 높았으며 김치 섭취의 교육도 필요하다고 하였다.

The purpose of this study was to examine whether the gender, grade and school type of middle school students made any differences to their sexual awareness and sexual behaviors in an effort to lay the groundwork for providing more efficient sex education. The research questions were posed as follows: First, what is the sexual awareness of middle school students? Second, what are the sexual behaviors of middle school students? Third, are their gender, school year and school type related to their sexual awareness and behaviors? The subjects in this study were 976 middle school students from Gyeonggi province. After a survey was conducted with questionnaires prepared by this researcher based on earlier studies to suit the purpose of the study, the collected data were analyzed with SPSS 10.0 program. The frequency analysis, x2 test and correlational analysis were implemented, and basic statistical data were obtained. The conclusions were as follows: First, regarding their sexual awareness, the largest group of them agreed that one must report in case of being raped(4.36), and the smallest number of them thought that one might have a sexual relationship with a person other than his or her spouse after marriage(1.56). Second, as for experience of indecent materials, part of sexual behaviors, 67.4 percent had ever contacted such materials. The most common medium through which they contacted them was the Internet(56.5%). The above-mentioned findings suggested that the sexual awareness of the middle school students wasn't influenced by gender or school type. But that varied with grade, as the third graders had the best sexual consciousness. Their sexual behaviors were different according to gender. The boy students contacted more indecent materials, and their experience of such materials varied with grade, since the third graders contacted the most obscene materials. And that also varied with school type, and the non-engineering students contacted more obscene materials. As for sexual drives, their masturbation experience was different according to gender, grade and school type. The number of the boys who practiced masturbation was four-fold larger than that of the girls, and the second graders had more such experience. By school type, the non-engineering students practiced more masturbation, but there was no significant gap between their kissing, caressing and dating experiences.

This study examined the mediation effect of life satisfaction between aggression and loneliness. The subjects were two hundred and eighty fifth-year elementary school and second-year middle school adolescents in Seoul. Data were analyzed by using the t-test, Pearson's correlation and regression. Major findings were as follows: First, when it comes to aggressiveness, the fifth graders showed a significantly higher degree of personal attack, whereas the eighth graders were found to show more expression of anger. The fifth graders scored higher than the eighth graders in each subcategory of life satisfaction. No significant difference was found in the category of loneliness. Second, the fifth graders showed a positive relationship among verbal attack, personal attach, expression of anger and loneliness, whereas the eighth graders showed a positive relationship between expression of anger and loneliness. The two age groups, in turn, also exhibited some differences in the relationship between loneliness and life satisfaction. Third, we found that life satisfaction is a complete parameter between aggressiveness and loneliness in the fifth graders. In the case of the eighth graders, life satisfaction turned out to be a partial parameter between aggressiveness and loneliness. This perhaps indicates that adolescents with similar levels of aggressiveness might show different degrees of loneliness, depending on whether they have positive attitudes toward their lives and whether they feel satisfied with their lives.

This study examined the mediating effect of self-concept on the relationship of peer victimization and social anxiety in middle school students. Study participants consisted of 235 (122 boys and 113 girls) first to third graders from three middle schools located in Seoul and Gyung-gi province. The School Violence Experience Scale and the Self-Concept Scale were used to measure research variables in the Korean version of Social Anxiety Scale for adolescents. Descriptive statistics and Pearson's correlation coefficients were calculated to examine the general tendency of study variables. In addition, structural equation modeling(SEM) was used to examine the mediating model. The study results were as follows. First, the level of peer victimization of the middle school students decreased the self-concept level; in addition, the self-concept level had a significant negative effect on the social anxiety level. Second, the self-concept level fully mediated the peer victimization and social anxiety relationship. In conclusion, a higher peer victimization level resulted in a lower self-concept level, that produced a higher social anxiety level in middle school students. The results suggested that implementing effective interventions to prevent peer victimization and encouraging a positive self-concept in middle school students would make a significant contribution to reducing social anxiety.

Objective: The purpose of this study was to investigate the relationship between sleep duration and school adjustment of elementary-, middle-, high-school youth and to verify the mediating effects of parenting behavior. Methods: We analyzed the data from Wave 4 of the first-grade panel of elementary school and Waves 1 and 4 of the first-grade panel of middle school in Korean Children and Youth Panel Survey (KCYPS), including 1,703 fourth graders, 2,119 seventh graders, and 2,108 tenth graders. Multiple regression was used for the data analyses. Results: The results of this study were as follows. First, longer sleep duration was associated with a higher level of school adjustment in fourth grade. In contrast, longer sleep duration was associated with a lower level of school adjustment in seventh and tenth grades. Second, longer sleep duration was related to a higher level of discipline through reasoning in fourth grade. However, longer sleep duration was related to a lower level of parental monitoring in seventh and tenth grades. Third, the relationship between sleep duration and school adjustment was mediated by parenting behavior. Discipline through reasoning had a mediating effect in fourth grade, but the mediating effect of parental monitoring was found in seventh and tenth grades. Conclusion: These results suggest a differentiated approach on sleep duration in accordance with developmental stage and the need for parent education.

The purpose of this study was to examine the relationship between social networks and perceived self-competence. The subject were 350 third and sixth graders selected from a public elementary school in Seoul. The children were administered the Pattison Psychosocial Network Inventory and The Self Perception Profile for Children. Three major questions are addressed; l)age changes 2)sex differences, and 3) the relation between the characteristics of social networks and self-perceived competence. Data were analyzed by pearson's product moment correlation, one-way ANOVA. Proportion measures were also used since they had allowed for the observation of relationship between two subsets of people within given categories(e.g.,the number of relatives divided by the number of relatives plus nonrelatives). The effects of age and sex of child on the number and daily contact with kin, nankin, peers, adults, males, and females were found. Sixth graders had a larger number of adults than third graders. While children had a greater number of adults than peers, they had more contact with peers than with adults in their network. It was found that boys had greater number of people in their network than girls. And boys had a larger number of and more contact with males, and girls had a larger number of more contact with females. The structure of childrens' social networks structure were correlated with perceived self-competence.

This study set out to investigate the relations between middle school students' perception of body image and their allowance for plastic surgery, to understand their perception of body image and desire for plastic surgery, and provide some data needed to warn against reckless plastic surgery and guide the students effectively. For those purposes, an examination was conducted of the relationships between the individual characteristics and perception levels of body image, the individual characteristics and allowance for plastic surgery, and perception levels of body image and allowance for plastic surgery. The subjects were drawn from sour middle schools located in two regions of Gyeonggi Province. Total 922 boys and girls were surveyed on a questionnaire, which was developed based on the pretest of previous literature, reviewed for appropriateness, and tested for reliability and reasonableness. The body image on the five scale was greater as the perception level was higher. The allowance for plastic surgery was also greater as the scores were more. The findings were as follows: First, the relationships between individual characteristics and perception levels of body image were examined. The third graders showed the highest perception level, being followed by the first and second graders. The girls were more perceptive than the boys, and those who were extrovert were more perceptive than those who were introvert. Those students whose parents earned 2 million won or more a month and who adapted themselves to the environmental changes had a higher perception level. In a word, the girls from the middle class that were well adapted, felt happy, and were extrovert had a higher perception level of body image. Second, the connections between individual characteristics and allowance for plastic surgery were investigated. The third graders were the most admissive of plastic surgery, followed by the second and first graders. That is, the upper graders were more admissive of plastic surgery. In addition, the girls were more admissive than the boys, and those who were extrovert were more than those who were introvert. There were no significant differences according to the monthly income of the parents, grades, adaptability to surroundings, and happiness, which results almost resembled the findings of a study conducted on adults. Third, there were negative correlations found between the perception levels of body image and the allowance for plastic surgery. To elaborate, the higher the perception levels were, the lower the allowance was, and vice versa. As for the items, the subjects showed more allowance for plastic surgery when they scored less in the item of caring about appearance, importance of looking pretty to others, and efforts to improve appearance. When they had a low value of body and easily felt tired, they were highly acceptive of plastic surgery. The allowance for plastic surgery was also great when their perception was much of how healthy they felt, how important they felt about their bodies, how they were satisfied with their current appearances, how they evaluated the appearance of others, how much they were satisfied physically, and how much demanding they were for physical changes. Meanwhile, there were no correlations between the allowance and physical attraction, the degree for one's activities to be hindered, and sickness. In short, the demand for plastic surgery was 41% for the girls and 20.2% for the boys. Just as the study on adults reported, those who had a low or negative perception of body image were more acceptive of plastic surgery. The middle school students were generally positive about their bodies with the lowest perception level at 2.91 and the highest at 3.21. Their individual allowance for plastic surgery was related to their individual body images, which were in turn affected by the mass communication, surrounding environments, and social values. Thus it's necessary for the entire society to try to improve or change the overall perception. Helping measures should be taken so that the students can form right sense of values about their bodies, avoid the obsession with appearance and appearance-based evaluation, and exercise righteous criteria against humans beings and things. In conclusions, the following suggestions were made: they need to develop such questionnaires or tools as can measure the body image of teens and fit the reality. Moreover, body image improvement programs should be more diverse and more applicable to teens. Despite the consistent reports that prove the correlations between body image and plastic surgery, there has been little effort to apply such factors as experience of the life of the disabled, volunteer activities for the disabled and at the hospitals, and others that can induce changes to body image to the body image improvement programs. In the future, comparative research should be carried out on body image and plastic surgery.

The purpose of this study was to establish objectives for ninth grade studies of heredity and evolution in middle school in an attempt to foster students' consciousness of bioethics, and it's additionally intended to develop and apply lesson plans handling different points at issue and to determine the effects of the lesson plans on the bioethics of middle school students. The subjects in this study were 152 ninth graders in a middle school, whose science scores were similar. An experimental group and a control group were made up of 76 students respectively, and a pretest was conducted with test paper developed by this researcher to assess their awareness of bioethics. The experimental group took lessons by using the teaching plans prepared in this study, and the control group received typical education according to the curriculum. And then a posttest was implemented with test paper developed in this study to compare the two groups. In addition their science grades were compared as well. The findings of the study were as follows: First, seven learning objectives were selected from three units related to bioethics in the third-year 8th category of heredity and evolution of middle school. Second, in order to attain the selected learning objectives, four session lesson plans were prepared. Third, the experimental group that studied using by the lesson plans made better progress in bioethics awareness and the gap between the two was statistically significant(t=6.61, p<.001). The former were ahead of the latter in consciousness about species equity(t=7.71, p<.001), the dignity of life (t=3.78, p<.001), human rights(t=2.99, p<.01) and equity among generations(t=2.66, p<.01), but not in awareness of the diversity of species. Fourth, there was no significant gap in science scores between the students studied according to the curriculum and those who received instructions by using the lesson plans developed in the study.
