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.

This Study explored three issues in regard to the determinants of community service utilization among family caregivers of the dependent older persons. First, the differences between users and nonusers of community services were compared regarding to predisposing, enabling, need characteristics of the primary caregiver as well as the elder care recipient. Second, the variables which determined the contact of community services were examined. Third, the influence of the variables on duration of the community services among users was also examined. The data collected from 164 family caregivers were used for analyses. Findings suggest that community service users had higher education and higher emotional support, lower family income than nonusers. The level of cognitive impairment of the elder was also higher for users than nonusers. The entry into community services is more likely for elders cared for by caregivers who have higher educational attainment, lower family income and lower level of instrumental support. Once interaction terms for relationship between need factors and social support are entered, caregivers with poorer level of his/her perceived physical health and lower level of instrumental support are more likely to report use of community services. Among those reporting contact with services, more extensive use occurs for caregivers with lower emotional support and lower depression. The entry of interaction terms for relationship between need and support reveals that the combination of lower support(instrumental and emotional) and elder's greater physical impairment are associated with longer period of community service use. However, the effect of caregivers' depression followed the different pattern. For caregivers with greater depression, more supports are related with more service utilization. According to the results, implications for research and practice are discussed.

The present paper reports the effect of precursor alumina particle size on pore structure and single gas permeation properties of tubular ${\alpha}$-alumina supports, prepared by a combined process of slip casting and sintering. Pore diameter of as-prepared ${\alpha}$-alumina support was highly dependent on precursor ${\alpha}$-alumina particle size. Although, increase in the precursor particle size increases the pore diameter, but the porosity of ${\alpha}$-alumina support mainly control by sintering temperature. Sintering studies reveal that as sintering temperature increased porosity of support decreased. Single gas permeance results indicate that permence is proportional to the square of pore diameter and linearly to porosity. These dependencies revealed that gas permeation trough as-prepared ${\alpha}$-alumina support was governed by viscous flow mechanism. The present announces that precursor ${\alpha}$-alumina particle size and sintering temperature are key parameters to control gas permeantion properties of ${\alpha}$-alumina supports.

There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.

Biodegradable polymers have been used extensively as scaffolding materials to regenerate new tissues and the ingrowth of tissue have been reported to be dependent directly of the porosity, pore diameter, pore shape, and porous structure of the scaffold. In this study, porous poly (L-lactide-co-glycolide) (PLGA) scaffolds with five different pore sizes were fabricated to investigate the effect of pore sizes for AF tissue regeneration. Cellular viability and proliferation were assayed by MTT test. Hydroxyproline/DNA content of AF cells on each scaffold was measured. sGAG analyses were performed at each time point of 2 and 6 weeks. Scaffold seeded AF cells were implanted into the back of athymic nude mouse to observe the difference of formation of disc-like tissue depending on pore size in vivo. We confirmed that scaffold with $180{\sim}250{\mu}m$ pores displayed high cell viability in vitro and produced higher ECM than scaffold with other pore sizes in vivo.

This study explored how the family resilience of participants in self-sufficiency programs relates to their willingness to be self-sufficient and analyzed the mediating effects of family support in the relationship. The subjects of the study were 283 people in their 20s to 70s who are participating in a local self-sufficiency center in Gangwon-do. Statistical analyses were conducted using IBM SPSS 18, with descriptive statistics, difference verification and regression, and mediating effects analyzed following Baron & Kenny(1986). The results of the analysis are as follows. First, we conducted difference verification between the sociodemographic characteristics of participants in the self-sufficiency program and major variables. There was a significant difference in the willingness to be self-sufficient in terms of the caregiving family and household income. Family resilience differed significantly depending on age group, marital status, health condition, household type, caregiving family, and homeownership, while family support differed significantly in age group, marital status, health condition, household type, caregiving family, and debt. Second, we conducted a hierarchical regression analysis to determine the factors influencing the will of self-sufficiency of those participating in the self-sufficiency program and found that the better the health condition, the presence of caregiving families, and the higher the level of family resilience and family support, the higher the level of will to be self-sufficient. Third, analyses of the mediating effect following Baron & Kenny(1986) have shown that family support has a full mediating effect on the relationship between family resilience and the will to be self-sufficient. Thus, we have verified that family resilience and family support are important factors as an alternative to improving the level of willingness for self-sufficiency program participants.

In this study, we explore whether and how the experience of discrimination and social support affects physical health and mental health through disability identity among the disabled aged 50 and over. We also examine such relationship differs by the degree of disability. For the empirical test, we utilized the data from the Panel Survey for the Disabled conducted by our research team in 2016. According to structural equation model analysis, social support has a direct effect on disability identity. It also has a direct effect on physical health. As for the mental health, there are found direct effects of discrimination experience, social support, disability identity, and physical health, Furthermore, social support influences the mental health through disability identity. This finding suggests that social support for the disabled in old age increases disability identity and, in turn, it contributes their mental health. In the meanwhile, multiple group comparison analysis reveals the effect of discrimination experience on disability identity is found for those with lower level of disability but not for their counterparts. This seems to result from that the level of common ground which constitutes disability identity is low for the severely disabled. Thus, it requires our efforts to enhance disability identity focusing on common ground for the severe disabled.

The purpose of this study is to investigate the effects of stress, social support, and resilience on the university life as predictors of college life adjustment. For this purpose, the questionnaires were administered to 145 college students in Busan, and correlation analysis, multiple regression analysis, and mediation analysis were conducted using SPSS 18.0. The main results are as follows. First, the significant factors influencing college life adjustment were stress (B = -.351, p <.01), social support(B = -.210, p <.05) resilience (B = .355, p < .01), 30.6% explanatory power, and resilience was the most influential factor. Among the sub-factors of stress, interpersonal stress and academic stress has a negative effect. In addition, friendship support had a statistically significant effect on social support, and resilience subscale was life satisfaction and cause analysis ability. In addition, stress was found to be partly mediated in the relationship between social support and college life adjustment. Based on this study, the strategies for lowering the stress, improving the resilience of the university students in order to improve the college life adaptation were provided.
