A survey on Korean families′purchase of fresh fruits and vegetables was conducted to increase understanding of families′food decision making. Two hundred ninety seven families with at least one elementary-school age child were selected from four elementary schools to complete a questionnaire during April, 2001 in Gyeongju, Korea. Descriptive statistics, Chi-square test, T-test, and ANOVA statistics were used to analyze the data. The major findings are as follows: Families bought fresh fruits and vegetables at the public markets or the farmer′s markets and a large supermarket most frequently in both summer and winter. Families grew produce by themselves and bought them from farmers directly least frequently in both summer and winter. Families whose housewives had less than middle school education brought fruits and vegetables from Agricultural Co-ops and grew thens by themselves more frequently compared to those who had higher education. On the other hand, families whose housewives had graduated from 4 year college bought fruits and vegetables from large supermarkets more frequently compared to those who had lesser education. "Quality"and "safety production"of fruits and vegetables and "clean environment of store"were the three most important factors when they decided the place to buy fruits and vegetables. "Being treated as a valuable customer" and "ease of finding things"were the two least important factors. Families whose housewives were in their thirties valued "cleanness of the store"and "being treated as a valuable customer"important factors when they decided the place. Families whose housewives had less than middle school education thought that price, availability of public transportation, and availability of locally grown food were the important factors for deciding the place compared to those who had higher education. The price was the factor which low-income families thought important for decision making on the place to buy fruits and vegetables.

The Ministry of Education (2015) announced the "2015 Revised Curriculum for Elementary and Secondary Schools" and announced that SW (Software) training for elementary and junior high school students to develop Computational Thinking will be gradually introduced from 2018. In addition, 'problem solving' and 'programming' have become important areas. Furthermore, the ability to analyze and utilize big data is becoming more emphasized. We developed and applied the statistical - Python programming convergence curriculum based on the idea that convergence education combining information and mathematics, programming and statistical literacy is needed according to current trends. Before and after the experiment, problem solving ability test and programming / mathematical interest test were conducted and compared with the corresponding sample t-test. According to the analysis results, there were significant differences in the pre- and post-test on problem solving ability, programming interest and mathematical interest at the significance level of 0.05.

The purpose of this study was to investigate the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles. The subjects were 399 middle school students and 366 high school students in four middle schools and two high schools in metropolitan and small towns for one month from July 1, 2017. Data were analyzed through descriptive statistics, correlation analysis. Multiple regression was used to see how parent-adolescent communication styles, self esteem, and depression affect the career decision-making style. As a result, first, open communication with mothers has a statistically significant effect on the rational career decision-making style and open communication with fathers has a statistically significant effect on the intuitive career decision-making style of adolescents. Second, self-esteem of adolescents showed a positive correlation with rational career decision-making style and negative correlation with dependent career decision-making style, and depression showed a positive correlation with dependent career decision-making style. The results may help to understand the relationship among the parent-adolescent communication styles, self-esteem, depression and career decision-making styles and be used for counseling intervention.

The purpose of this study was to find out the relationship between self-esteem and mental health in Middle school students, and provided basic data to develop a nursing program for the prevention of mental disease and the promotion of mental health in adolescence. Subjects were 153 students in the third year of three middle schools located in K city. Instruments used in this study were the self-esteem questionnaire developed by Choi, B. K. & Jun, G. Y.(1993) and the simplified SCL-90 developed by Lee, H. K.(1986) for measuring mental health. Data were analyzed by Cronbach's alpha, descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient by using SPSS/PC+ program. It was found that the mean score of the self-esteem was 3.20. The score of self-esteem in family was high and the score of self-esteem in school was low. The mean score of mental health was 1.94. The scores of depression, obsessive-compulsive and interpersonal sensitivity were high, the scores of phobic anxiety and somatization were low. There were significant differences among religions (F=2.709, p= .032), and between personalities (t=-2.285, p= .024) with respect to self esteem. There were no significant differences between general characteristics variables and mental health. However there was significant negative correlation between the mean self-esteem score and the mean mental health score (r=-.431, p= .000). In conclusion, mental health is strongly related to self-esteem. If and adolescent who suffers from mental health is not received proper treatment, his or her mental health prohibits him from managing sound social life even after grown-up. Thus, nursing intervention in adolescence should be developed to enhance the self-esteem of adolescence and to help him raise sound mind.

Also, the girls got higher nutrition knowledge score than the boys did and the students in Taejeon got higher nutrition knowledge than those in Ahnmyeondo. 2. The higher the economic level was, the higher the frequency score(intaking food) was. Also, the students whose father had the occupation involved in the tertiary industry and better school ing made higher nutrition knowledge, eating attitude, and frequency intaking food than others. The students whose father had the occupation involved in the tertiary industry and better schooling were taller and heavier than others. 3. The variables influencing on the frequency intaking food were father's school ing, father's occupation, economic level, sexual distinction, eating attitude. The variables influencing on eating attitude significantly was only the birth order.

Purpose: This study was conducted to compare the postural habits, body image, and peer attachment of adolescents with idiopathic scoliosis and healthy adolescents, and to examine the correlation between body image and peer attachment in each group. Methods: Eighty-three adolescents with idiopathic scoliosis and 83 healthy adolescents were recruited from 4 middle schools located in W city. Data were collected from November 22 to December 6 2010 using a structured questionnaire including items about postural habits, body image, and peer attachment. Data were analyzed using descriptive statistics, $X^2$-test, independent t-test and Pearson Correlation Coefficient. Results: Compared to healthy adolescents, adolescents with idiopathic scoliosis were more likely to use one hand, to lean back while seated, and to put weight on one leg while standing. The score for body image was significantly lower for adolescents with idiopathic scoliosis compared to healthy adolescents, but peer attachment was not significantly different between the two groups. Body image was significantly correlated with peer attachment only for the adolescents with idiopathic scoliosis. Conclusion: Interventions to promote balanced postural habits in adolescents with idiopathic scoliosis are needed. Information on body image and peer attachment for these adolescents should also be considered when developing interventions.
