Objective: This study investigated 5-year-old children's developmental levels for creative and social personalities according to gender, and whether participation in STEAM-based unplugged robotic activities can improve their creative and social personalities. Methods: Participants were 5-year-old children (N=125) from 11 child care centers. The experimental group included 29 boys and 24 girls enrolled in classrooms that implemented an unplugged activities curriculum over five weeks. The control group consisted of 38 boys and 34 girls. Data were analyzed using a t-test and analysis of covariance, and Hedges' g was used to measure effect size. Results: First, the participating children's mean scores on creative and social personalities were 3.20 and 3.53 on a 5-point Likert scale, respectively. Girls scored higher than boys in sensitivity-various interests and imagination-playfulness domains of creative personality and all three domains of social personality. Second, children in the experimental group showed improvement in all domains of social personality and the effect size was large. They also improved in three domains (openness-humor, imagination-playfulness, independency-immersion) of creative personality, although the effect size was small. Conclusion/Implications: The results imply that implementing a robotics curriculum with unplugged play activities in early childhood classrooms contributes to 5-year-old children's development of creative and social personalities.

Objectives: Understanding recent trends in cigarette smoking among adolescents is important in order to develop strategies to prevent cigarette smoking. The aim of this study was to compare recent trends in cigarette smoking for adolescents living in rural areas, small towns and metropolitan cities in Korea. Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) from 2005 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Logistic regression models were used to evaluate significant linear time trends in cigarette smoking. The indicators of cigarette use behaviors were 'current smoking rate', 'frequent smoking rate', 'heavy smoking rate' and 'smoking experience rate before 13 years of age'. All analyses were conducted according to gender. Results: Statistically significant increasing trends in current smoking rate and frequent smoking rate were observed and borderline significant increasing trends in heavy smoking rate were shown among rural boys. Among metropolitan city boys, statistically significant increasing trends were also seen for frequent smoking. Statistically significant decreasing trends in current smoking rate were observed among small town and metropolitan city girls. Smoking experience rate before 13 years of age for rural girls decreased significantly. Conclusions: Cigarette smoking prevalence among adolescents in the rural areas has increased in the last five years especially among boys. Our findings suggest that anti-tobacco program for adolescents should be conducted primarily for those in rural areas.

Eating breakfast provides crucial nutrition for brain function and helps promote overall health. It is especially critical in growing adolescents, as it is known to form good eating habits and better study habits. This study investigated the effects of skipping breakfast on nutritional state, fatigue level, and attention level. A cross-sectional study was conducted in 2010 on total of 828 adolescents composed of 414 boys and 414 girls. Students who ate breakfast never to twice per week were placed in the breakfast-skipper group while students who ate breakfast more than five times per week were included in the breakfast-eater group. Students performed a self-reported questionnaire on food behaviors, amount of food consumption, fatigue level, attention deficient hyperactivity disease (ADHD) level by Conners-Wells' Adolescent Self-Report Scales, depression scale, and self-esteem level. Statistical analysis was conducted using the SAS program (version 9.1). A total of 135 boys (32.6%) and 138 girls (33.3%) were included in the breakfast-skipper group, whereas 241 boys (58.2%) and 223 girls (53.9%) were included in the breakfast-eater group. The breakfast-skipper group showed irregular food behaviors and lacked nutrients. Specifically, energy (p< .001), protein (p< .001), dietary fiber (p< .001), calcium (p< .01), vitamin A (p< .01), thiamin (p< .05), niacin (p< .001) levels in boy breakfast-skippers were statistically lower compared to boy breakfast-eaters. Intakes of all nutrients except fat in girl breakfast-skippers were statistically lower than in girl breakfast-eaters. Girl breakfast-skippers (41.3%) showed significantly higher fatigue risks compared to girl breakfast-eaters (21.5%). Low attention level was also observed only in girls in the breakfast-skipping group. Moreover, students in the breakfast-skipper group showed higher scores for depression and low self-esteem (p< .001). In conclusion, skipping breakfast has effects on young adolescents' nutrition, manifesting as high fatigue level and low attention level, especially in girls.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. In order to choose suitable shoes for feet, the foot size and shape must be considered, so it is essential to grasp the exact size and shape of the foot. This study aims to present fundamental data on shoes' easy order prototype development for choosing shoes of good wearing comfort, by classifying feet size and shape junior high school boys in the early adolescent period. The subject were 234 Korean junior high school boys age from 14 to 16 years old. The subjects were directly measured anthropometrically and indirectly analyzed photographically. 6 factors were extracted through factor analysis and those factors comprised 79.42% of total variance. The factors characterizing foot girth and width, foot length, foot height, foot shape around the fifth toes, angle of foot breadth and foot shape around the first toes. 3 clusters as their foot shape were categorized using 6 factor scores by cluster analysis. Type 1 was characterized by long large foot with deformed first toe. Type 2 had smaller in foot girth, width and length than other types and with deformed fifth toe. Type 3 had average size and high foot shape. Shoes prototype which is to be developed later on will be able to generate 2D flattening in the foot sole form. Therefore, it would be a great support in producing and choosing appropriate shoes if forms are classified by subdividing foot form classification and extract a factor which shows only the foot sole shape.

To establish good dietary behavior for middle school students, this study was conducted to analyze the needs of nutrition education and eating attitudes of 373 middle school students(boys 171, girls 202) in Hwaseong city. Using questionnaires, results were gathered and analyzed. Dietary behavior, food group intake and the needs of nutrition education were scored by a five-point Likert scale. Chi-square and student t-test were done for significant gender difference. The correlation between the needs of nutrition education with dietary behavior and food group intake was obtained by Pearson's r. The dietary attitude of 'try to eat first' and 'eating fast' were higher score in boys than in girls(p<0.05). Most of the students thought they didn't have any nutritional problems(71.8%). Nutrition education was considered necessary(54.9%) for proper growth and development(53.0%) in middle school. But 45.1% of students did not suggest by the reasons of 'short time to change'(28.2%), 'more effective in home'(27.4%). The appropriate time of nutrition education was pre-school(28.2%) or elementary school(27.4%), once a week(boys 51%, girls 71.3%) in frequency(p<0.001), and the information acquired by TV/Radio(30.0%) and internet(26.6%). Students(46.0%) wanted to know about 'growth and nutrition'. They were to learn information on the 'healthy growth'(4.10) and 'adolescent nutrition'(4.03). The vegetables group consumption and the thought of dietary attitude 'try to modify bad eating habits' were correlated with almost all categories of desired nutrition education. Through these results, good eating habits would be attained by nutrition education. A nutrition education program would require an expert teacher for middle school students.

The purpose of this study was to set up the basic model to monitor the health status of the middle and high school students in the adolescent period, as well as to provide the fundamental data which might serve as the new standards for their better health maintenance and promotion. The collected data comprised the characteristics of the subjects in the three different fields of life such as school, family and everyday, which could affect their physical fatigues, and they were analyzed to determine the factors of significant influence upon their physical fatigues and to reveal their relativity. A total of 5,954 students at 6 boys' and girls' middle and high schools in Taejon City completed self-administered questionnaires(to measure Health Practice Index and others) asking about each of three life domains during the period March through June, 2000. The key study results were as follows; 1. The middle school students showed more subjective symptoms of fatigue which may be a marker reflecting physical health status, than the high school students. The higher scores were associated, based on school life, with the groups who were boys, who were in lower school grades, who achieved better academic performances and had better relationship with friends. 2. As for family life, the higher scores were in the groups whose financial conditions were better, whose parents showed more interest to their children, whose sense of satisfaction with family life was higher, and whose health status was better. 3. As for life styles, the individuals showed the higher scores in the groups who had breakfasts daily, who didn't have inter-meal snacks, who took regular exercises, who didn't smoke and drink than, their counterparts. 4. The higher level of fatigue was associated with the groups whose health conditions were good, who are satisfied with school life, who were boys rather than girls, who are satisfied with family life, who didn't have inter-meal snacks, who were in good relationship with friends, who achieved greater academic performances, who took regular exercises, who didn't smoke, and whose parents showed more interest in their children.

Objectives: The purpose of this study was to examine the association between participation in physical activities (PA) and subjective well-being. Methods: We analyzed the data from Korean Youth Risk Behavior Web-based Survey, 2013 containing 36,655 and 35,780 for male and female students respectively. Study variables included PA, participation in physical education class, participation in team sports and subjective well-being. Control variables were school type, socio-economic status, level of parent education, living with parent, academic performance, delinquent behaviors, depression and perceived health. For this study, descriptive analysis, Chi-square test, and multivariate logistic regression analysis were performed. Results: Among boys, after adjusting for control variables, PA (past 7 days 0 time reference group vs. over 4 times: OR 1.306), physical education class (past 7 days 0 time reference group vs. over 3 times: OR 1.140), and team sports (no team reference group vs. 2 team: OR 1.206) were associated with subjective well-being. Among girls, control variables were adjusted. PA (past 7 days 0 time reference group vs over 4 times: OR 1.244), physical education class (past 7 days 0 time reference group vs. over 3 times: OR 1.161), and team sports (no team reference group vs. 2 team: OR 1.181) were associated with subjective well-being. Conclusions: Participation in physical activities may help adolescent promote their life satisfaction. Thus, education experts should develop various exercise curriculums to encourage participation in physical activities.
