Background : Several studies have suggested different arguments for the effect of stretching exercises and core muscle exercises on flexibility and balance ability. Objective : To determine the effects of stretching exercises and core muscle exercise on flexibility and balance ability. Design : Quasi experimental research Method : The study applied exercise interventions (three sessions per week for 6 weeks) on 40 subjects. The subjects were divided into stretching and core muscle exerciseing groups to identify the change of flexibility and balance ability. Sit- and- reach test results and hip hyperextension were measured for identifying changes in flexibility, and the Romberg test and Pedalo stabilizer were used for changes in balance ability. Results : Both the stretching exercise and core muscle exercise groups showed a statistically significant increase in flexibility (p<.05). However, the stretching exercise group showed a statistically significant increase in balance ability (p<.05), whereas the core muscle exercise group showed partially statistically significant differences in this par t(p>.05). In the analysis of the differences in the amount of change in flexibility, based on the types of exercise, stretching exercises showed a significant difference (p<.05), whereas a significant difference was not found in the amount of change in balance ability (p>.05). Conclusions : These findings indicate that stretching exercises are the more effective intervention for improving and maintaining flexibility, whereas there is no difference between stretching and core muscle exercises with respect to improving balance ability.

Purpose: This study aimed to identify factors influencing quality of life in post-menopausal women. Methods: The participants were 194 post-menopausal women who visited a women's clinic in Changwon, Korea from July 1 to August 31, 2018, and completed questionnaires containing items on menopausal symptoms, marital intimacy, current menopausal hormone therapy (MHT), and quality of life. Collected data were analyzed by descriptive statistics, the independent t-test, Pearson correlation coefficients, and multiple regression using SPSS for Windows version 23.0. Results: Quality of life had a significant negative correlation with menopausal symptoms (r=-.40, p<.001), and a significant positive correlation with marital intimacy (r=.54, p<.001). The factors influencing the quality of life of post-menopausal women were current MHT (t=6.32, p<.001), marital intimacy (t=4.94, p<.001), monthly family income (t=4.78, p<.001), menopausal symptoms (t=-4.37, p<.001), and education level (t=3.66, p<.001). These variables had an explanatory power of 59.2% for quality of life in post-menopausal women. Conclusion: In order to improve the quality of life of post-menopausal women, nursing interventions are needed to help menopausal women choose appropriate MHT, alleviate menopausal symptoms, and increase marital intimacy. Interventions should also be prioritized for women of a low educational level and with a low income in consideration of their health problems.

Selfie behavior, the act of taking a picture of oneself and distributing it on social media, has become increasingly popular. Researching how to communicate with others in a social context and express hoped-for self through selfies is essential for studying consumers in the digital age. This study investigates the effects of reflected appraisals on selfie expectations and selfie behaviors. Additionally, the interaction effect of hoped-for self on the relationships between reflected appraisals and selfie expectations was tested. A web-based survey was conducted on consumers above the age of 20 who have engaged in selfie behavior in the past month. A total of 495 responses were collected from a panel of online survey firms. The survey results were analyzed using confirmatory factor analysis by AMOS 21.0 and bootstrap analysis by SPSS Macro process Model 4 and 7. Results indicated that reflected appraisals influenced selfie behavior, which was fully mediated by selfie expectations. Furthermore, the effect of reflected appraisals on selfie behavior was moderated by hoped-for self. The results will serve as a theoretical basis for understanding the psychological expectations in which selfie behavior is formed in a social context and can be applied in psychotherapy and marketing in practice.

BACKGROUND/OBJECTIVES: The association between nutritional status and health-related quality of life (HRQoL) among patients with type 2 diabetes mellitus (T2DM) is not fully understood. This study was conducted to understand the role of nutritional status on HRQoL among people with and without T2DM. SUBJECTS/METHODS: Structured survey and direct measurement of anthropometric data were conducted among people with and without T2DM. Nutritional status was measured with Mini Nutritional Assessment tool and HRQoL was measured with a 36-item Short Form Healthy Survey. Data collection was conducted in Chuncheon, South Korea with 756 participants who are older than 40 yrs of age. RESULTS: This study found that overall HRQoL were significantly lower in people with T2DM than people without T2DM after controlling for key covariates. When stratified by nutritional status, a greater degree of negative impact of T2DM on overall physical HRQoL was observed among well-nourished or at risk of malnutrition, whereas significant and more evident negative impact of diabetes on overall psychological HRQoL was observed only among malnourished. CONCLUSIONS: The study results suggest the role of nutritional status among people with T2DM on overall, especially psychological aspects of HRQoL. Future longitudinal or intervention studies are warranted to test the impact of nutritional status on HRQoL among people with T2DM.

In this study, the fit of commercial sports bras was analyzed according to various design variations, focusing on the shape of the shoulder strap, which is known to cause great discomfort in wearing sports bras. Experimental clothes were set to four commercially available sports bras with different shoulder strap shapes. The results showed that, in "size suitability," the overall satisfaction with experimental clothing B, of which the shoulder strap can be adjusted, was the highest, especially for "underbust circ. fit," "bust circ. Fit," and "shoulder strap length." In the "Shape suitability" and "Wearability" sections, experimental clothing B also showed the highest satisfaction and the shoulder strap adjustment device did not negatively affect wearing satisfaction. In the question on "side wings rolled up," experimental clothing A also received a relatively good score, which is due to its long front length. In the "Compression of the front center" section, the responses for experimental clothing A and B were "appropriate" and for C and D, they were "pressurized." In "motion suitability" as well, satisfaction with experimental clothing B was the highest, followed by experimental clothes A, C, and D. In the "body shape correction" section, clothing B elicited the highest satisfaction, followed by experimental clothes A, C, and D, in that order. Overall, it is recommended that shoulder straps be applied with adjustable straps for the comfort of the shoulder area while wearing sports bras.
