Purpose: The purpose of this study was to investigate factors influencing health promoting behavior of the late school age children and to analyze the difference of health promoting behavior according to personal factors of children. Methods: The subjects consisted of 169 school-aged children in the 6th grade in Gyeonggi-do. Data were collected from Dec. 1 to Dec. 10, 2008. The data were analyzed by using frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficients and Stepwise multiple regression with the SPSS/WIN 12.0 program. Results: 1) Health promoting behavior was proved to be relatively high. The average item score for the health promoting behavior was $3.85{\pm}.41$. The highest degree of health promoting behavior was stress management (4.13). whereas the one with the lowest degree was exercise (3.40). 2) In the relationship between personal factors and health promoting behavior, there were statistically significant differences in gender, perceived health status, family mood, father's drinking habits, school performance, school satisfaction. 3) Health promoting behavior was showed significant positive correlations with perceived self-efficacy (r=.55), social support (r=.65), prior related behaviors (r=.44), perceived benefits of action (r=.42), and significant negative correlations with perceived barriers of action (r=-.37). 4) Stepwise multiple regression analysis was revealed that the most powerful predictor of health promoting behavior was social support ($\beta$=0.36) Conclusion: The combination of social support, perceived self-efficacy, perceived benefits of action, gender, and family mood accounted for 57.8% of the variance in the health promoting behavior of the late school age children.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.

In this study, 100 consumers (men, 50; women, 50; age group, 20-50 years) rated their overall preferences for 24 Korean raspberry wines by using a 9-point hedonic scale. The analysis of variance was constructed to evaluate the effect of gender, age, and samples on the preference scores of the wine products. Significant differences were observed in overall preferences for the 24 samples; however, no interactions based on preferences by age and gender groups were noted. Cluster analysis was performed to determine sample clustering based on the frequencies from the preference data. Three clusters were obtained; these three clusters were well separated based on the mean overall preference scores for the samples. Discriminant analysis based on the three clusters also confirmed the same grouping of samples with 100% accuracy.

An experiment was conducted to examine the effects of sex and market weight on performance, carcass characteristics and pork quality. A total of 224 crossbred pigs (initially 26.64 kg BW) were allotted in a $2{\times}4$ factorial arrangement in a randomized complete block (RCB) design. The variables were sex (gilts and barrows) and different market weights (100, 110, 120 and 130 kg). Average daily gain (ADG) and average daily feed intake (ADFI) were significantly higher (p<0.01) in barrows than gilts, ADFI and feed conversion ratio (FCR) increased as body weight increased (p<0.05). Gender differences were observed in carcass characteristics. Backfat thickness and drip loss were greater in barrows (p<0.01), while loin eye area (p<0.01), flavor score (p<0.05) and lean content (p<0.001) were higher in gilts. Carcass grade and water holding capacity were the highest in 110 kg market weight pigs. The 100 kg arket weight pigs showed lower juiciness, tenderness, shear forces and total palatability than the other market weights (p<0.01). Hunter values (L*, a* and b*) were increased as market weight increased (p<0.05). Hunter a* value was greater in gilts (p<0.01) but L* value and b* value were not affected by sex of pigs. Net profit [(carcass weight${\times}$price by carcass grade)-(total feed cost+cost of purchased pig)] was higher in gilts than barrows (p<0.01), and was higher (p<0.05) in the pigs marketed at 110 and 120 kg market weight compared with 100 kg market weight. These results demonstrated that gilts showed higher carcass characteristics, pork quality, feed cost per kg body weight gain and net profit compared with barrows. Moreover, 110 or 120 kg body weight would be the recommended market weight based on pork quality and net profit for swine producers.

The purpose of this study was to compare college students' emoticon use for positive behavior and to analyze the impact of the factors. This study is consisted of 66 questions based on Social demographic characteristics, personality characteristics factors and both scales of emotional expression. The operational test was administered to 340 college students. In an effort to calibrate emoticon use of positive behavior, the results displayed significance differences depending on the gender and grade of the students. Women used more emoticons than men, and freshman used more emoticons than any other year of students. Women used more emoticons such as texts, images, and flash more than men. Students in their freshman year were shown to use more emoticons than students in other grade levels. Emotional expression was strongly related man with personality traits of integrity. Personality traits of sensitivity, openness, intimacy, and sincerity had a significant influence on the emotional expression. An emoticon is, therefore, be a useful tool to express their emotions. Male and female students with higher levels of congeniality had expressed more emotions that were self-defence ambivalent and concerned-relation ambivalent. However, in the case of the female students, those with higher levels of self-defence ambivalent emotional expressiveness had a lower usage of positive emoticons, while male students with higher levels of self-defence emotional expressiveness used more positive emoticons. Higher levels of congeniality among groups that use mobile emoticons with their parents, whether the frequency of use was high or low, were associated with higher levels of self-defence ambivalence and concerned-relation ambivalence. Those with higher levels of sincerity had low levels of self-defence ambivalence and concerned-relation ambivalence, and those with higher levels of concerned-relation ambivalence had higher levels of positive emoticon usage.

Purpose: This study aimed to grasp the correlation between communication ability, empathy, and interpersonal relations among nursing students, and to explore the mediating effect of empathy on the relation between communication and interpersonal relation in nursing students. Methods: Participants were 209 college students in the Department of Nursing at two universities. The data collection period was from October 1, 2019 to November 1, 2019. The questionnaire consisted of measuring tools for general characteristics, communication ability, interpersonal relation and empathy. SPSS/23.0 program was used. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. Results: The communication ability was nursing major satisfaction (t=8.25, p<.001), and last year's average grade (t=7.29, p=.001). Interpersonal relationships showed significant differences in gender (t=2.51, p=.013) and nursing major satisfaction (t=10.99, p<.001). Communication ability and empathy (r=.37, p<.001), communication ability and interpersonal relation (r=.77, p<.001), empathy and interpersonal relation (r=.43, p<.001) showed a significant static correlation. In communication ability and interpersonal relation, empathy had a partial mediating effect (Z=2.97, p<.001), and explanatory power was 62%. Conclusion: To improve the communication ability and interpersonal relation of nursing students, it is necessary to develop a personalized and empathy-enhanced education program for each grade.

The purpose of this study was to make a comparative analysis of dietary habits, snacks, eating out and fast-food intake between students with a relatively early sexual maturity and others with a relatively late sexual maturity in a bid to grasp the impact of dietary behaviors on sexual maturity. The subjects in this study were 565 boys and girls who resided in Seoul and Gyeonggi province. They included fifth- and sixth-grade school children and seventh-grade middle school students. To classify the selected students according to the level of sexual maturity, the students of the same month age were divided into two groups in consideration of the stage of their sexual maturity and that of the other age groups. The early mature group was significantly taller and weighed more than the late mature group irrespective of gender. According to Tanner stages, the boys of the early mature group reached a 3.03 stage of sexual maturity when the sexual organs were taken into account, and those of the late mature group reached a 1.50 stage of sexual maturity. The girls of the early mature group reached a 3.43 stage of sexual maturity on the basis of breast, and those of the late mature group reached a 2.73 stage of sexual maturity. Concerning eating out, the early mature group ate out more frequently than the late mature group. In regard to snacks, the early mature group had a snack more often. The findings of the study indicated that there were differences in physical development and some dietary behaviors according to sexual maturity. The early mature group had a snack and ate out relatively more often than the late mature group, which showed that some dietary behaviors had an impact on the sexual maturity of the teens who arrived at the age of puberty.

The purpose of this study is to determine which types of leisure activities promote happiness in young people. The ultimate goal of this study is to improve adolescents' levels of happiness and examine the academic and political challenges that occur in their social networks. In this study, subjects as "more than 4th grade of elementary school to less than a high school students". A sampling of the group was completed using a pre-percentage assignment and the data was analyzed according to gender and grade. The primary research method employed was internet research, and questionnaires were used as a secondary method of collecting information. The final analysis used 1.046 (final response rate 83.4%). The results of the present study were classified into the following four parts: social network and the characteristics of youths' subjective happiness; leisure activities according to the type of social network; differences in the level of subjective happiness organized according to the type of leisure activity; and the relative influence of variables that affect the level of subjective happiness. In conclusion, there is a strong correlation between social relationships, leisure activities, and youth's subjective happiness. An analysis of the difference in the level of subjective happiness according to the type of leisure activities of adolescents confirmed that the type of active participation in leisure and the type of indoor and outdoor activities variety were the highest in terms of contributing to the level of subjective happiness. Generally, a discussion of how the existing leisure life affects the subjective happiness of young people needs to be taken one step further. This difference was significant because the level of subjective happiness was confirmed according to the type of leisure activities. In addition, this study determined that leisure activities have an effect on subjective happiness and positively impact young people.

The purposes of this study were to investigate the intercorrelations among various motivational patterns and learning strategies and to examine the differences in motivation and strategy usage in terms of students' science achievement level, gender, and grade. A questionnaire on achievement goal, self-efficacy, self-concept of ability, expectancy, value, causal attributions, and learning strategies was administered to 360 junior high/high school students (178 males, 182 females). Students who adopted performance-oriented goal tended not to be task oriented. Task-oriented students had high levels of self-efficacy, high self-concept of ability, and expectancies for future performance in science. They also valued science and attributed thier failures to the lack of effort. However, performance-oriented students evaluated their ability negatively, did not value science, and attributed thier failures to uncontrollable causes. With respect to learning strategy, task-oriented students tended to use deep-level strategy, whereas performance-oriented students tended to use surface-level strategy and not to use deep-level strategy. High-achieving students, boys, and junior high school students were more task-oriented, evaluated their ability more positively, and valued science more than low-achieving students, girls, and high school students, respectively. High-achieving students and boys also used deep-level strategy more than each of their counterparts. However, no significant difference in learning strategy was found between junior high school students and high school students. Educational implications of these findings are discussed.

This study reflects the demand of content elements related to "Human Reproduction" in elementary school science curriculum, and verifies its effects by developing and applying sex education contents available to elementary science class. The developed contents is composed of three sections in reference to the contents guideline for teachers. The contents include anatomical knowledge related to human reproduction and reflect social and cultural context of sex ethics. The first section: "How was I born?", second section: "Amazing changes in my body" and third section: "Healthy body, healthy mind." In the result of analysis of changes in sex knowledge and attitude after applying the contents, it showed statistically significant differences between experimental and comparative class. Thus, the developed contents made positive influence on improvement in elementary students' knowledge and attitude of human reproduction. However, it showed little difference in the effects of sex education contents by the grade and gender. In conclusion, if the sex education contents developed through this study is actively applied, it is expected to provide the elementary students with knowledge of the anatomic difference between male and female, its social and cultural understanding and responsibility for sex ethics. In addition, it is considered to be used as effective education programs and materials in elementary school science curriculum.
