Purpose: The purpose of this study was to identify aging anxiety and influencing factors of middle-aged adults. Methods: Descriptive correlation design was used. Three hundred and three middle-aged adults participated in the study and completed the questionnaires in the period from September 11 to October 15 of 2011. The data was analyzed using independent t-test, one-way ANOVA, Scheff$\acute{e}$ test, Pearson correlation coefficients, and hierarchial multiple regression analysis. Results: Aging anxiety of middle-aged adults was higher than a moderate level. Socio-demographic variables such as age, religion, education, economic level, perceived health status and experience of living with older adults influenced significantly on aging anxiety. In contrast, general self-efficacy, aging knowledge and attitude toward older adults were negatively correlated with aging anxiety. Hierarchial multiple regression analysis incorporating these variables showed an explanation rate of aging anxiety at 21%. And religion, perceived health status, attitude toward older adults, and general self-efficacy were statistically significant among variables that influence on aging anxiety. Conclusion: The findings of this study suggest that senior preparation programs that can enhance self-efficacy, induce positive attitude on older adults and promote health should be implemented to reduce aging anxiety of middle-aged adults.

Purpose. This study was conducted from the period of April 12th, 2017 to April 26th, 2017. The questionnaires were distributed among a group of 76 adults aged 20 years or older, who participated in the prevention program of the department of dental hygiene at Busan Metropolitan City. The negative questionnaire was finally analyzed. Methods. The SPSS program was used for analysis of this study. The general characteristics of the subjects were t-test and one-way, ANOVA(by Scheffe post-test) for a PHP index (Patient Hygiene Performance index) according to frequency analysis, general characteristics, smoking and drinking behavior, and dietary behavior. Results. As a result of an examination of the PHP index(Patient Hygiene Performance index) ac- cording to smoking and drinking behavior, the amount of alcohol drunk was statistically higher than that of 'soju that was not drunk'(P<0.05). As a result of the PHP index (Patient Hygiene Performance index) according to dietary behavior, 'vegetarians' were statistically higher than 'Carnivorous oriented' individuals (P<0.05). Moreover, individuals who regularly 'drank almost no water' were statistically significantly higher than those who 'drank water steadily'.(P<0.05). Conclusion. As a result, appropriate management is required for oral health of the patient, Oral health education is needed to systematically consider smoking, drinking, and eating habits when taking into consideration the individual oral environment.

Textile Reinforced Cementitious Composite (TRCC) became the most common construction material lately and have excellent properties. TRCC can be employed in the manufacture of thin-walled facade elements, load-bearing integrated formwork, tunnel linings or in the strengthening of existing structures. These composite materials are a combination of matrix and textile materials. There isn't much research done about the usage of polymer modified matrices in textile reinforced cementitious composites. In this study, matrix materials named as fine grained concretes ($d_{max}{\leq}1.0mm$) were investigated. Air entraining effect of polymer modifiers were analyzed and air void content of fine grained concretes were identified with different methods. Aim of this research is to study the effect of polymer modification on the air content of fine grained concretes and the role of defoamer in controlling it. Polymer modifiers caused excessive air entrainment in all mixtures and defoamer material successfully lowered down the air content in all mixtures. Latex polymer modified mixtures had higher air content than redispersible powder modified ones. Air void analysis test was performed on selected mixtures. Air void parameters were compared with the values taken from air content meter. Close results were obtained with tests and air void analysis test found to be useful and applicable to fine grained concretes. Air void content in polymer modified matrix material used in TRCC found significant because of affecting mechanical and permeability parameters directly.

This study examines the relationships between dietary self-efficacy, social support, depression, and weight-control behavior of children and adolescents. A total of 593 students (280 children and 313 adolescents) from schools in Seoul, Gyeonggi-do, Jeollabuk-do, and Daegu were surveyed using scales for dietary self-efficacy, social support, depression, and weight-control behavior. The data were analyzed through a frequency analysis, means and standard deviations, a t-test, a one-way ANOVA, the Tukey test, the Pearson's correlation, and a stepwise multiple regression analysis. According to the results, weight-control behavior was more likely in girls than boys, high-school students than elementary-school students, and obese/overweight students than normal/underweight students. The factors influencing children's weight-control behavior were general eating habits, the BMI, depression, food choice, and family support, in that order, and those influencing adolescents' weight-control behavior were general eating habits, gender, and the BMI, in that order. These results are expected to be useful as basic data for developing weight-control programs for children and adolescents.

This study examines the relationship between social support with adult children and neighbors on the life satisfaction of elderly individuals in rural areas. The analysis employed a sample of 764 elderly individuals residing in rural area. Data were analyzed through descriptive statistics, a chi-square test, a t-test, and a multiple regression analysis. First, the respondents reported moderate life satisfaction. Those respondents living alone were less likely to report life satisfaction than those with a spouse. Second, the respondents were more likely to be in contact with their neighbors than their adult children. Third, the respondents were more likely to receive social support from adult children than provide it to them. By contrast, the respondents were more likely to provide social support to neighbors than receive it from them. Fourth, economic status and contact with adult children and neighbors had signigicant effects on the life satisfaction of the respondents. Gender, religion, economic status, health status, increased contact with adult children, and instrumental support to neighbors had positive effects on the life satisfaction of elderly two-person household.
