The purpose of this study was to provide basic data on counseling, education, and treatment related to orthodontic practices through an understanding of the relationships between orthodontic treatment, oral health-related quality of life, and happiness of high school students. The subjects in this study were 500 students in Grades 1~3 of a high school in Jeollabuk-do. We conducted a survey targeting this group; the results revealed the following: in the social support item, peer support showed significant differences in the matter of orthodontic treatment (p<0.05). In oral health-related quality of life, the students without orthodontic treatment showed 14.09 scores that were higher than the students with treatment (p<0.05). Regarding happiness, the students with orthodontic treatment showed higher scores which were significantly different from the those of the non-orthodontic treatment group (p<0.05). Additionally, upon examining the correlations between self-esteem, social support, oral health-related quality of life, and happiness, oral health-related quality of life, peer support, and happiness showed the negative (-) correlations while the rest of the variables showed the positive correlations (p<0.05). The factors having effects on oral health-related quality of life included the stress, matter of orthodontic treatment, and teachers support (p<0.05). The factors having effects on happiness included self-esteem, peer support, and family support (p<0.05). Based on the above results, even though dental orthodontic treatment had negative effects on oral health-related quality of life, it had positive effects on happiness. Consequently, it would seem necessary to seek active methods to increase oral health-related quality of life. This improvement could be achieved by minimizing inconveniences, such as mastication, in the process of dental orthodontic treatment, and developing programs that could enhance happiness.

Methods: Data were collected from Gangwon and Chungchong provinces from the first to the $15^{th}$ of October, 2016. Excluding five copies with incomplete answers, 203 copies of the questionnaire were were analyzed. Health risk behaviors (drinking and smoking), perceived oral health, OHIP-14 and happiness were measured. The data were analyzed with a t-test, one-way ANOVA, Pearson correlation coefficient and multiple regression using the SPSS 22.0 program. Results: The amount of daily cigarette consumption of soldiers (66 people) was an average of 10.11 cigarette. The mean of OHIP-14 and that of happiness were 4.43 and 4.05, respectively. The higher the quality perceived oral health, the better the OHIP-14 (r=0.234) and happiness (r=0.192) were. The higher the OHIP-14, the higher the happiness (r=0.357). OHIP-14 was related to army, perceived oral health and happiness. The explanatory power of the model was 17.0%. Conclusions: OHIP-14 is associated with happiness.

The purpose of this research was analyzing pre-post change of concept recognition structure about happiness and activity in which medical school students feel happiness, in order to develop such curriculum accordingly. Research subjects included a total of 36 sophomores attending medical school, and a day reconstruction method and network analysis were applied. According to the research finding, while medical school students were experiencing a lot of happiness while eating/talking and doing leisure activities, the frequency of feeling happiness through learning activities was shown to be low. Words that expressed happiness before and after were similar in many parts and 'economy' showed the highest degree centrality before and 'work' showed the highest degree centrality after. Because the structure of the concept about happiness was divided from 1 group into 4 groups including one's work, positive self, health of family, value about life etc., perception of the concept about happiness was changed from the concept about superficial happiness to the concept about actual happiness. Therefore, in order for prospective doctors who will treat human health to establish the concept and value about happiness properly, education about happiness is necessary and for this, curriculum related to happiness must be developed systematically.

Data were collected from 277 nursing students from April 16 to May 4, 2018. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Life stress, body image, happiness, and health promoting behaviors according to the general characteristics commonly showed significant differences in major satisfaction and school satisfaction. Health promoting behaviors showed positive correlations with body image and happiness, but a negative correlation with life stress. Happiness, body image, life stress, gender, and major satisfaction, which accounted for 46% of the variance, were significant predictors influencing health promoting behaviors in nursing students. Based on the results of this study, it is necessary to develop a variety of programs to lower life stress and increase body image and happiness in order to improve health promoting behaviors of nursing students.

The participants consisted of a total of 961 women who were the mothers of preschool children, school aged children, and adolescents. The mothers completed a questionnaire on the perceptions of the conditions of happiness which consisted of a total of 56 items. The results of this study revealed that mothers in their 20's and 30's, with high levels of education, and on high incomes were more likely to have high expectations regarding most of the conditions of happiness compared to mothers in their 40's and 50's, with lower levels of education, and on low incomes. In addition, the results further revealed that mothers perceived that 'children grow up well and healthy' as being the most important factor in their happiness regardless of the life cycles of their children. In particular, mothers with younger children tended to give greater priority to a close mother-child relationship in their happiness. However, when mothers' demographic variables were controlled, there were no differences in maternal perceptions of the conditions of happiness across the life-cycles of their children.

The subjects were surveyed in 2018 by the Korea Youth Policy Institute, and out of 2,739 elementary school students, unresponsive and missing values were removed and the final 1,978 were selected. As a result of the analysis, it was found that leadership life skills were completely mediated in the relationship between volunteer work and subjective happiness of elementary school students. For the analysis method, SPSS 25.0 program was used to achieve the purpose of this study. And to verify the mediating effect, a 3-step mediating effect analysis was performed by Baron & Keeny(1986). It was confirmed that leadership life skills were completely mediated in the relationship between self-development activities and subjective happiness. Based on these research results, in order to increase the subjective happiness of elementary school students, measures were discussed to develop practical skills that can improve communication and organizational management skills, which are leadership life skills.
