This study was conducted for the evaluation of the effects of singing program combined with physical exercise on the physiologic changes, perception function and degree of depression. The subjects were the members of elderly women's glee club in D care center for the elderly, who have been singing for more than 6 months. 30 members were allocated to study group and 30 to control group. The singing program designed for both physical therapy and music therapy was consisted of initial physical exercise, singing art songs and classical song and the finishing physical exercise. This program was performed twice a week and about forth minutes was consumed for one session. We checked the heart rate, peripheral arterial oxygen saturation, perception function and degree of depression before and after the program. We used a pulse oxymeter to check the heart rate to oxygen saturation and a questionnaire for the evaluation of perception function and degree of depression. We need SPSS program for data analysis. The results of the investigated personnel complying with general characteristics were analyzed by frequency, two groups by t-test, data before and after the program by paired t-test, respectively. The results were as follows. 1) Heart rate after the program was significantly lower than that before program in test group(p<0.05). 2) Peripheral oxygen saturation after the program was significantly higher than that before the program(p<0.05). 3) Ability to match the right sign with a certain predetermined number was improved after the program. The frequency of wrong matching the sign with number before program was 30. But the frequency was decreased to 8 after the program. 4) Ability to calculate was improved after the program. The frequency of wrong calculation before the program was $1.10{\pm}1.94$. But the frequency after the program was decreased to $0.97{\pm}1.84$. 5) The degree of depression after the program($2.07{\pm}0.49$) was significantly lower than that before program(p<0.001). These results show that singing program combined with physical exercise improves the oxygen delivery to peripheral circulation, stability of heart function, the perception function(calculating and matching ability) and decreases the degree of depression. In conclusion, singing program combined with physical exercise can be used for the effective measure to improve the health of elderly and prevent dementia.

Purpose: To investigate factors influencing the evaluation of background parenchymal enhancement (BPE) at follow-up breast magnetic resonance imaging (MRI) after adjuvant endocrine therapy. Materials and Methods: One hundred twelve women with breast cancer and MRI of the contralateral unaffected breast before and after endocrine therapy were identified. Two readers in consensus performed blinded side-by-side comparison of BPE (minimal, mild, moderate, and marked) before and after therapy with categorical scales. Age, body mass index, menopausal status, treatment regimen (selective estrogen receptor modulator or aromatase inhibitor), chemotherapy, follow-up duration, BPE at baseline MRI, MRI field strength before and after therapy, and recurrence were analyzed for their influences on decreased BPE. Results: Younger age, premenopausal status, treatment with selective estrogen receptor modulator, MRI field strength, and moderate or marked baseline BPE were significantly associated with decreased BPE. In multivariate analysis, MRI field strength and baseline BPE showed a significant association. Conclusion: MRI field strength and baseline BPE before and after therapy .were associated with decreased BPE at post-therapy, follow-up MRI.

Objectives: This study investigates dietary supplement intakes by examining the characteristics of dietary and health-related behaviors. Data were obtained from the Korea National Health and Nutrition Examination Survey (KNHANES). Dietary and health-related behaviors were also examined before and after the occurrence of COVID-19 and household types (multi-members vs. single person). Methods: Data used in this study were collected from the 2019-2020 KNHANES by including adults aged 19 to 64 years. Pregnant, lactating, and subjects consuming calories less than 500 and more than 5,000 were excluded. Differences in dietary and health-related behaviors before and after COVID-19, and between the two types of households were analyzed by Chi-square analyses using Rao-Scott. Logistic regression analyses were applied to determine which dietary and health-related behaviors affected the dietary supplement intakes. In addition, descriptive analysis was run for demographic characteristics. Results: The dietary supplement intake rate differed significantly with respect to the gender, age, education, marital status, and household income. Dietary supplement intakes, frequency of eating out, obesity, and body weight changes were significantly different before and after COVID-19. In addition, meal evaluation, frequency of eating out, drinking, smoking, activity, subjective health evaluation, and body weight changes showed significant differences by household type. Attitude towards nutrition, activity, meal evaluation, obesity, and smoking were factors that affected the intake of dietary supplements. Conclusions: While increased intake of dietary supplements is a prevalent phenomenon, this intake needs to be monitored and studied closely, considering the sociodemographic characteristics and dietary and health-related behaviors. Furthermore, the dietary supplement intake trend after COVID-19 needs to be studied along with food intake.

Nutrition education in elementary school is confronted with the present problem, as a legal basis about obligation of nutrition education in school was clarified. Moreover, it's also important for providing evidence based scientific resources to make a study of evaluating the education effectiveness. Most studies of the nutrition education effectiveness have evaluated the changing dietary attitude and nutritional knowledge score before and after the nutrition education, and suggested the effectiveness of intervention as changing between pre- and post-treatment. Nutrition education, however, purposing long-term changes, follow-up evaluation process about the learned attitude and knowledge of nutrition education were requested. For these reasons, this study attempted to fulfilled standardized nutrition education program which use "Na Story and Food World" and "Na Story for Me", a textbook for the 1st-3rd grade and 4th-6th grade designed by KFDA, and analyzed the changes about the effectiveness of nutrition education happened over a period of time. In this study, each student was assessed their dietary attitude and nutritional knowledge by four periods, before the education, right after the education, after 3 months, and after 6 months. As a result, an average score of nutritional knowledge before the education, $70.08{\pm}17.91$, were changed significantly higher right after the education to $85.69{\pm}15.05$ (p < 0.001), but it lowered to $84{\pm}15.56$ after 3 month. After the nutrition education, students in all grades had positive dietary attitude to Na reduction (p < 0.001). However, the healthy eating attitude about Na reduction had been unable to maintain after 3 and 6 months. Therefore, the systematic reeducated program in elementary school was positively necessary to reinforce children's learning and cognitive skills to maintain healthy eating knowledge and attitude toward Na reduction.
