The purpose of this study was to evaluate diet-related Quality of Life (QOL) and to analyze the relationship among diet-related QOL, dietary regimen practice, health-related QOL, and gastrointestinal symptoms in hemodialysis patients. Subjects were recruited from an artificial kidney center in Seoul. The self-report questionnaire consisted of socio-demographic characteristics, diet-related QOL, compliance with dietary regimen practice, health-related QOL, and gastrointestinal symptoms was distributed. Diet-related QOL includes a 'Quality of Life and Related to Dietary Change Questionnaire', 'Satisfaction Survey', and 'Dietary Impact Survey'. According to their responses, participants had experienced the greatest difficulty with 'Dietary Impact'. In particular, the mean score for general health was low. Association of dietary regimen practice showed a positive association with 'Cost' and 'Self-care' score. In addition, diet-related QOL showed positive correlation with health-related QOL, particularly in 'taste'. Scores for 'Taste', 'Convenience', and 'Dietary Impact' were lower for subjects with constipation compared to those of subjects without constipation. Scores for 'Taste' and 'Dietary Impact' were lower in subjects with irritable bowel syndrome compared to those of subjects without the syndrome (p < 0.05). Diet-related QOL showed a positive association with health-related QOL (p < 0.05), whereas it showed a negative association with constipation (p < 0.01). In conclusion, hemodialysis patients in Korea suffer from burden of dietary regimen practice and most scores for diet-related QOL and health-related QOL from patients with gastrointestinal symptoms were low. Therefore, appropriate nutrition education considering gastrointestinal symptoms is necessary for improvement of patients' QOL during dietary regimen practice.

The purpose of this study was to investigate social networks, loneliness, and sleep quality related to health-related quality of life in older adults living alone. Data were collected from 111 community-dwelling elderly. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regressions with IBM SPSS 26.0 program. In multiple regression analysis, physical component summary (PCS) was predicted by the level of education (β=.20, p=.020), social networks (β=.31, p=.012), and sleep quality (β=-.23, p=.011). The model including these variables accounted for 25.7% of the variance in the PCS. Mental component summary (MCS) was predicted by loneliness (β=-.37, p=.004). Loneliness accounted for 31.7% of the variance in the MCS. In order to enhance the health-related quality of life of the older adults living alone, the intervention program to resolve social isolation should be provided for them.

The purpose of this study is to provide basic data for confirming the convergence relationship between flexibility exercise on quality of life, oral condition, and oral health-related behavior. Data from the 2012 KNHNES were used, and complex sample linear regression analysis and logistic regression analysis were performed to confirm the effects of flexibility exercise on quality of life and oral health. As a result, those who controlled for demographic characteristics and did not exercise flexibility had .027 times worse exercise ability among the subcategories of quality of life, and .152 times higher number of carious permanent teeth. Among the symptoms of temporomandibular joint disorder, pain symptoms were 1.633 times higher in those who exercised flexibility (p<.05). Therefore, it is considered that flexibility exercise has value in that it has suggested a relationship not only with general health but also with oral health.

This study examined the effects of the demographic and health characteristics and chronic diseases on the health-related quality of life in service employees. From January 1, 2013 to December 31, 2014, this study analyzed the data on 607 service employees based on the 2nd data of the 6th National Health and Nutrition Examination Survey with at-test, ANOVA, and hierarchical regression analysis use of SPSS. The results of the analysis showed that the quality of Life in women was lower (${\beta}=-.074$, p=.050) than that of men, and the older the subjects were, the lower their quality of life(${\beta}=307$, p=.000). Regarding the subjective health status, there was a significant increase in the "very Poor"(${\beta}=186$, p=0.027) and "good"(${\beta}=196$, p=.001) status. The quality of life improved with increasing activity (${\beta}=-0.222$, p=0.000)). Some of the subjects perceived "high stress" (${\beta}=-0.123$, p=0.003) and the others perceived "low stress"(${\beta}=-0.176$, p=0.000). The less they perceived stress, the higher their quality of life. The factors explained 24.6％ of the health-related quality of life of the subjects. Therefore, to improve health-related quality of life of service employees, more activity opportunities should be given, the subjective health status should be positively perceived and psychological measures to decrease the level of stress should be developed.

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.
