The purpose of this study was to investigate predictors and mediating effects of physical activity and nourishment regulation on well-being among young and middle aged patients on DM medication and to compare between those with non-pharmacological treatment and those without. Data were obtained from 2017 community health survey including 1,480 DM patients with oral medication in the age between 20 and 49. Using SPSS 25.0 and AMOS 25.0, path analysis was performed to explore the association between personal factors (socio-economic status, health habit, eating habit and compliance of health examination) and well-being, along with mediating effects of physical activity. Results demonstrated the different mediating role of physical activity. In medication only group, there was no direct effect of physical activity and no indirect effect of personal factors. Direct effect of physical activity and indirect effects of predictors were found in those with non-pharmacological treatment group. When developing strategies to enhance well-being of young and middle aged diabetic patients, proper reflection of their age specific traits and disease management capability are essential.

This study measured physical characteristics and physical composition of 16 middle-aged obese women using a body composition analyzer. TC, TG, HDL-C and LDL-C were investigated in order to analyze components of serum liquids. The study also compared changes regarding cardiovascular risk factors before and after a 12-week exercise program by measuring insulin and intensity of TNF-$\alpha$. To examine such changes, the study carried out a 12-week, complex training program for middle-aged obese women who did not regularly exercise. The results of the study were as follows: 1) after 12 weeks of complex training, in changes of physical characteristics, weight, BMI and WHR were significantly reduced. Systolic blood pressure and diastolic blood pressure increased, but there were no significant differences; 2) after 12 weeks of complex training, in changes of physical composition, body fat mass and body fat rate were significantly reduced and fat free mass was significantly increased; 3) after 12 weeks of complex training, in changes of serum liquids, TC, TG and LDL-C were significantly reduced. HDL-C increased, but this was not statistically significant; 4) after 12 weeks of complex training, in changes of cardiovascular risk factors, insulin and TNF-$\alpha$ were significantly reduced.

The purpose of this study was to find texture which suitable for the acryl knitted jacket of women in the middle age. The study was carried out 2 parts. The first part was to choose the pattern fitted in the body shape of women in the middle age, and the second part was wearing test with 3 different textured acryl knitted jacket(half milano, milano, jacquard). The usable data of the test were coded for further statistical analysis including descriptive statistics (frequency and one way-ANOVA test, Student-Newman-Keuls Multiple Range Test) by using SPSSWIN 12.0. The results were as follows: It was found that first evaluation for the appearance test on fitness, pattern B(Brand: Morado) were better than the rest of them(pattern A: Trieste, pattern C: Escalier). It was found that second evaluation for the test, jacket with jacquard were better than the rest of them. Acryl knitted Jacket of women in the middle age should made of jacquard. Therefore it should be designed as possible as considering the physical characteristics of knitted materials. It was found that third evaluation for the test, it was opposite results that a general knitted fabric pattern was made smaller than a woven jacket. So, it was necessary that the acryl knitted jacket of women in the middle age follow a similar site tolerance such as a woven jacket. This result was due to a radical change of a middle age women's body shape.

This study was to know the effects of massage on the back region in order to reduce stress in middle age women. To investigate the effects of massage to the stress levels of middle aged women, we evaluated blood pressure (BP), heart rate variability (HRV), and ultrasonography before and after back massage. The blood pressure after massage was reduced when compared to that of pre-massage. The HRV spectrum analysis was used Frequency domain analysis such as Mean HRV, normalized low frequency (norm LF), norm high frequency (norm HF), and LF/HF ratio. Post-massage BP tended to be low, but not statistical significant. After Massage, the Mean HRV, norm LF, and LF/HF ratio were significantly reduced, while norm HF was significantly increased as compared with pre-massage. The muscle layer and fat layer were significantly diminished by massage. The study was suggested that massage may be an effective treatment for relief of stress.

The purpose of this study is to investigate how level of digital information usage of the middle-aged or elderly people affects life satisfaction and whether social capital mediates the relationship between level of digital information usage and life satisfaction. In this study, we analyzed data of 1,661 people aged 55 or older from the 「2018 Survey on Digital divide」 by the National Information Society Agency. The SPSS 25.0 statistical package was used for the mutiple regression analysis and Baron and Kenny(1986)'s steps for mediation. The statistical significance of the mediated effects of social capital was verified by the Sobel Test. As a result of the analysis, the aged people have a higher life satisfaction when they are women and older, do not live alone, have higher levels of digital informatization usage and social capital. In addition, social capital also revealed to have a mediating role between level of digital information usage and life satisfaction. This shows that social capital needs to be considered along with the level of digital information usage as a way to improve life satisfaction of the middle-aged or the elderly people.

Objective: This questionnaire study aimed to estimate the overall frequencies of positive perception towards orthodontic treatment among adults categorized according to age, sex, and area of living, and to identify barriers or negative perceptions preventing them from receiving orthodontic treatment. Methods: The participants included 598 adults aged over 20 years (230 men and 368 women) who visited the Dental Hospital of Seoul St. Mary's Hospital. The participants' opinions regarding their consideration of receiving orthodontic treatment were recorded using a specially designed questionnaire. Results: The overall rate of positive perception towards orthodontic treatment was 48.5%. Compared to adults in their 20s (63.2%), those in their 40s and 50s had a lower percentage of interest in orthodontic treatment (46.2% and 45.1%, respectively; p < 0.05). Overall, women (52.2%) had a higher rate of interest than did men (42.6%; p < 0.05). The area of living had no effect on the percentage of interest. The order of priority of chief complaints differed according to age: protrusion for those in the 20s and 30s, and spacing for those in the 40s to 60s. Overall, the main reason for not seeking treatment was the treatment fee. Respondents aged over 40 considered themselves "too old" for orthodontic treatment. Conclusions: The middle-aged had a relatively high percentage of interest (above 45%) in orthodontic treatment. However, demographic characteristics were not significantly associated with the positive interest. These results highlight the need for educating the middle-aged about the limitations and possibilities of orthodontic treatment to increase its acceptance.
