The purpose of this study is to present a practical class design model that applies the problem-based learning (PBL) method to the subject of home economics. To begin with, a specific class model example was developed by conducting thorough document research and expert consulting. Two modules, named "Click! Global Leisure Environment" and "Happy Leisure Product Launching" were presented as the PBL questions. The case study focused upon in this research is an elective course called "Leisure Culture and Life Management". The 21 students enrolled in this course were considered in this study. Two teaching methods, namely a face-to-face teaching method and a web-based system "Snowboard" teaching method, were used to run the class. The research results are as follows: first, theoretical research and program development and demonstration were practiced with five different age groups: childhood, adolescence, university student, middle age, and senescence. Then, selfevaluation, peer evaluation, and group evaluation were conducted to motivate the students. Finally, a class evaluation was conducted by questioning the lecturer, who ranked well, scoring higher than or equal to 4.0 points out of 5.0 on all the questions. Through the PBL method, students showed an improved study attitude with more proactive participation in the class, they strengthened their communication skills and created a synergy with their team members. This study has significant meaning because it is the first research to apply the PBL method to home economics. Therefore, we expect other curricula to apply PBL and fully utilize this teaching method as well in the future.

Objective: The purpose of this study was to gain an understanding of parenthood of mothers of early school-age children, with emphasis on cognitive, behavioral, and emotional aspects of parenthood. Methods: Nineteen mothers whose children were 1st and 2nd grade elementary school children participated in this study. Data were collected through individual in-depth interviews. During the interview, mothers were asked to speak freely about their experiences as parents of early-school age children, including parenting beliefs, parenting behaviors, and emotional experiences related to parenting. These interviews were transcribed verbatim and analyzed in a thematic way using MAXQDA. Results: Using qualitative methods, five major themes were emerged: (1) Recognizing the role of parents as a supporter of growth; (2) recognizing parenthood of the present generation that imposes expanded roles to mothers; (3) co-parenting of early school-age children and marital relationship; (4) co-existence of different parenting styles based on specific mother-child interaction situations; (5) experiencing a wide spectrum of emotions including anxiety, guilt, and depression, as well as happiness. Conclusion: This study revealed the unique cognitive, behavioral, and emotional aspects of parenthood experienced by mothers with early school-age children. Results of this study can fill a gap in our understanding of parenthood of mothers when their children entered into the new developmental stage of middle childhood. The results could also be used as a basis for developing parent education and family relationship programs.

The present study examined the effect of parent-adolescent communication style and school life satisfaction on the relationship between depression and suicidal ideation among adolescents. The participants were 1,099 middle school and high school students in Chungnam province. The instruments used were the 'Parent-Adolescent Communication Inventory', 'The Center for Epidemiological Studies Depression Scale', 'Suicidal Ideation Questionnaire', and 'School Life Satisfaction Scale'. The collected data were analyzed by t test, F test, the Scheff$\'{e}$ test for a post hoc test, Pearson's productive correlation, hierachical multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program(18.0 version). The results were as follows: First, there were significant differences in parent-adolescent open communication style, school life satisfaction, and suicidal ideation by school level, and in the relationship with the teacher in school life satisfaction by gender. Second, the more depressed they were, the more they had suicidal ideation by school level and gender. Also, the more they communicated openly with their parents and the more satisfied they were with their school life, the less depressed they were and the lower degree of suicidal ideation they had. Finally, there were significant effects of both parent-adolescent communication style and school life satisfaction on the relationship between depression and suicidal ideation among adolescents.

Through a questionnaire survey of 607 respondents over 20 years old currently residing in Seoul, general conditions, items and amount of daily diet, preference of dining-out and instant food, and concern for health were surveyed and the results are as follows. A large portion of respondents, at 36.2% of all respondents, were 20 years old, 57.7% of them graduated from high school or over, and most of them(61.9%) were over middle-class level of living standard. More than half (50.9%) of whom paid less than 10% for dining-out took breakfast as a rule, and 38.3% of whom regularly took meals and 37.3% of them took their regular daily routines. But among whom spent more than 31% for dining-out 46.2% of them took snacks between meals every day. Also, among whom spent more then 31% for dining-out, about 25.6% of them usually dined out every day. On concerns for health, among whom spent less than 10% of dining-out expense, 53.9% of them took exercise almost every day and 32.8% for 30 minutes, and 34.6% of them were generally healthy and 67.5% of them had normal blood pressure. But among whom spent more than 31% for dining-out expenses, 10.3% of them were not healthy, 15.4% had higher blood pressure and 20.5% had lower blood pressure, thus those portion were relatively higher compared with the former group. From those research results, therefore, group who spent lower dining-out expenses were older people with lower educational and living level but regularly took breakfast and exercise. Thus, their daily schedules were routine and took regular meals with healthy condition. The group with lower dining-out expense took right food pattern and kept healthy condition, and, therefore, it implied that dining-out gave significant influence to food pattern of grown-ups. Therefore, nutrition education for grown-ups might be necessary again and our foods as a diet should be re-evaluated and re-highlighted. To formulate the practical nutrition education in early childhood, practical, systematic, and continuous nutrition education might be required and effective and multidimensional education programs should be developed. In addition, various menus of breakfast with diverse materials, wide range of nutrition, and being convenient and time-saving must be studied in the near future.

Purpose : To identify changes and relationships in the fat mass and obesity associated (FTO) gene polymorphism, body composition, and physical fitness from childhood to adolescence over a three-year period spanning elementary school to middle school (2015-2018) Methods : A total of 84 male student participants were divided into two groups based on FTO genotype: aa+at (group A) and tt (group T) and tracked down. Body composition, cardiovascular endurance, flexibility, muscle strength, power, and other characteristics were measured in the two groups in both 2015 and 2018, respectively, and the changes over the three-year period were analyzed and compared. Results : Increases in height and weight did not differ significantly between the two groups, but body mass index (BMI) was significantly higher in group A (p=.035). With regard to physical fitness, there was no significant difference in flexibility, but cardiovascular endurance, strength, and power were significantly higher in group T (p<.001, p=.063, and p=.040, respectively). Conclusion : Group A is more likely to become obese than group T because of their lower level of physical fitness and increased BMI relative to group T. This result supports previous studies showing that group A has a relatively low level of physical activity and a greater tendency to eat fatty foods as compared with group T. Therefore, we suggest that the FTO gene polymorphism should be identified early and that students educated on diet and physical activity to help prevent adult obesity.

This study examined the effects of children's negative emotionality, emotional regulation, and maternal parenting behaviors on their relational and overt aggression. The participants were 355 children(174 boys, 181 girls; aged 4-5 years old) and their mothers. The teachers completed rating scales to measure the children's aggression and emotion regulation. The children's negative emotionality and maternal parenting behaviors were assessed by a mother reported questionnaire. The collected data was analyzed using descriptive statistics, t-tests, correlations, and hierarchical multiple regressions. Results showed that Children's negative emotionality was positively related to their relational and overt aggression. Children's emotional regulation had a negative relation to their relational and overt aggression. Mother's limit-setting and rejection-neglect was significantly related to children's relational aggression, whereas mother's warmth-encouragement and rejection-neglect was negatively related to children's overt aggression. Hierarchical regression analysis indicated that the interaction of children's negative emotionality and mother's overprotection-permission predicted children's overt aggression. Children's negative emotionality, whose mothers demonstrated middle and high level of overprotection-permission, was associated significantly with overt aggression. In addition, the association between mother's parenting behaviors and children's aggressions were mediated by their emotion regulation. The findings point to similarities and differences between relational and overt aggression in relation to children's negative emotionality, emotional regulation and maternal parenting behaviors.

The purpose of this study was to examine the differences of the perceptions and conditions of happiness between children and adolescents, and also of the perceptions of happiness according to their needs level of the conditions of happiness. There was a total of 649 participants, of which 405 were children and 244 were adolescents, all of whom were attending elementary school, middle school, or high school. The children and adolescents completed a questionnaire on the perceptions of happiness and the conditions of happiness which consisted of 57 (for children) or 58 (for adolescents) items. The results were as follows: First, children and adolescents both felt happy regarding the variables of 'flow', 'health and appearance', 'leisure' and 'interpersonal relations'. However, it was found that children felt happier than adolescents. Second, children and adolescents perceived achievement-related variables as important conditions of happiness. Additionally, variables of 'relations with parents and relatives' and 'positive emotions' were the conditions that children needed. However, adolescents rated the needs of the conditions of happiness higher than children. Lastly, children and adolescent groups who perceived the necessity of the conditions of happiness at a high level were found to be happier than those who perceived the necessity of the conditions of happiness at a low level. The findings have implications of providing educational, psychological and environmental support to improve the happiness of children and adolescents.
