Diet is important for muscle health and offers a protective effects against the loss of skeletal muscle mass and physical functions with advancing age. We analyzed the relationship between diet, metabolic disease risk, and sarcopenia in Korean female adults using the 2009-2011 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 2038 adult women aged 50-64 years were classified into four groups based on the diagnosis of menopause and sarcopenia. The groups were the non-menopause and non-sarcopenia group (NMNS, n=249), the non-menopause and sarcopenia group (NMS, n=14), the menopause and non-sarcopenia group (MNS, n=1,653), and the menopause and sarcopenia group (MS, n=122). The socio-demographics, anthropometrics, blood profile, and dietary data of the subjects were collected. Those who were in both the sarcopenia groups were more obese (p<0.001), had greater waist circumferences (p<0.001), higher body mass index (p<0.001), and higher obesity rates (p<0.001) after adjustment for covariants. Both the sarcopenia groups also had higher plasma levels of total cholesterol (p<0.001), HbA1c (p=0.001), and vitamin D (p=0.020) than both the non-sarcopenia groups. Both the sarcopenia groups demonstrated a decreased intake of calcium (p=0.05), potassium (p=0.008), and niacin (p=0.008) than both the non-sarcopenia ones. Among the four groups, the NMS group showed the highest levels of total cholesterol, obesity, and lowest intake of micronutrients such as calcium, niacin, and potassium. Thus, muscle mass maintenance through weight control and adequate nutrient intake appears to demonstrate a potential association with preventing sarcopenia in Korean middle-aged women.

Purposes: We analyzed the profitability determinants of regional public hospitals during the entire period between 2010 and 2020 and the period before and after COVID-19. We intended to provide fundamental data for developing publicness evaluation index and task of establishing and expanding regional public hospitals. Methodology: The financial and non-financial information of the regional public hospitals were used as the main analysis data; The financial data was established by the Center for Public Healthcare Policy of National Medical Center, and the non-financial data by the Health Insurance Review and Assessment Service. T-test and regression analysis were used. Findings: The results can be summarized in two. First, the main determinants of profitability of the regional public hospitals were appeared to be the total asset turnover rate and the labor cost rate. Second, during the COVID-19 pandemic in the regional public hospitals, the number of sickbeds, the number of isolation rooms, the total asset turnover rate and the labor cost rate appeared to be the factor worsening the profitability. Practical Implication: The results of this study suggests that the management of the regional public hospitals is not aiming for the profit making, but it performs the functions as the community healthcare safety net such as controlling infectious diseases.

PURPOSE: The purpose of this study was to investigate the effects of sensory motor training using ball exercise on shoulder range of motion, pain, dysfunction, and quality of life in Breast Cancer Women after Mastectomy. METHODS: A total of 26 patients from D University Hospital in Daejeon were included and randomly allocated to two groups (n=13 per group). The two groups performed the exercise five times a week for 4 weeks. A sensory motor training group (SMTG) received general physical treatment for 10 minutes and sensorimotor training for 20 minutes. A control group (CG) received general physical therapy for 30 minutes. Shoulder pain (the Visual Analog Scale), range of motion, disability (the shoulder pain and disability index) and quality of life (the Functional Assessment Cancer Therapy-Breast instrument) were measured in both groups before and after 4-weeks intervention. RESULTS: A significant difference was found in joint range of motion, shoulder pain, functional disability level, and quality of life within the two groups (p <.05). In addition, changes in joint range of motion, pain, functional disability level, and quality of life after then intervention were significantly different between the two groups (p <.05). CONCLUSION: These results suggest that a sensory motor training program is feasible, safe, and suitable exercise for shoulder functions and quality of life in Breast Cancer Women after Mastectomy.

Objective: This study aims to explore the relationship between isokinetic strength training and the enhancement of physical function in older adults. It also evaluates the effectiveness of isokinetic strength training equipment. Method: This study randomly divided twenty healthy adults into two groups.The experimental group engaged in isokinetic strength training for 30 minutes, three times a week, over a four-week period. In contrast, the control group did not participate in any exercise regimen. We assessed several outcome measures including physical functions (sit-to-stand test, flexibility, Timed Up and Go test), grip strength, balance, thigh circumference, the Korean version of the Patient Health Questionnaire-9 (PHQ-9), and the Korean version of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Additionally, the experimental group's self-perceived improvement in lower limb condition was evaluated using the Global Rating of Change (GROC) scale. Results: The experimental group showed significant improvements compared to the control group in various aspects: reduced sit-to-stand test duration (7.00±2.05 seconds), increased flexibility (4.69±3.90 cm), improved grip strength (1.54±1.74 kg), increased thigh circumference (left: 1.29±1.19 cm, right: 1.19±1.27 cm), enhanced Timed Up and Go test performance (-1.47±0.86 seconds), better balance (eyes open stance: -8.08±4.03 cm, eyes closed stance: -0.27±0.13 cm/s), and a decrease in depression severity (-0.15±1.51 points). Furthermore, significant increases were observed in the experimental group's maximal isokinetic strength at 90°/s for both flexion (19.62±7.03 Nm) and extension (19.60±14.65 Nm) over the study period. Conclusion: The findings suggest that isokinetic strength training equipment can significantly enhance physical functions in seniors when incorporated into an exercise regimen.

It is not stipulated concretely in the Food Sanitation Act what the standardized school food service dieticians indices and the dietician's duties and task elements should be. Therefore, this study was required. The specific purposes of this study were : a) to define the school food service dietician's duties and task elements, b) to estimate the performance frequency and work hours of the dietician's duties and task elements c) to investigate the job specification of the dietician over school food services, d) to develop the standardized indices of the dietician needed in school food service operation. For this study, school food service dietician's work functions were defined in 10 duties and 60 task elements based on the studies precedented and literature review and pilot test process. This study was conducted in school food service systems nationwide using written questionnaire and interview with the official in charge and delphi technique. The questionnaires were mailed to the dieticians of three types of school food service systems. Of the 660 schools that participated in this study, the 624 responses were selected for analysis. Statistical analyses were performed with SAS/Win 6.12 program so as to provide a descriptive statistics, T-test, ANOVA. The main results of this study could be summarized as follows: A characteristic common to all the school food service systems was that 'cooking and distribution management' took the longest hours of work, while 'nutrition education' took the shortest hours of work. The standardized index of dietician over school food service was one person in conventional system independently of the number of meals per day. In the commissary system, according to the numbers of meals served per day, it was 0.95-1.38 persons and 1.27-1.55 persons and 1.40-1.91 persons. In joint management system, the standardized index was 1.03-1.42 persons in case of serving less than 700 meals per day.

Objective : The study aims to investigate the effect of moxibustion treatments on autonomic nervous system function of cancer patients through the evaluation of heart rate variability (HRV) biofeedback testing. Materials and Methods : Six cancer patients from inpatient care unit of Dunsan Oriental Hospital, Daejeon University were given three moxibustion treatment sessions every other day over one week period on five Oriental Medicine meridian points CV4, CV6, CV12, KD1, and PC8. HRV biofeedback was conducted before and after each treatment sessions. Three areas of analyses were done from the test conducted; Time Domain Analysis, Frequency Domain Analysis and Autonomic Nervous System (ANS) balance analysis. Results : Time Domain Analysis has shown increased Standard Deviation of all Normal R-R Intervals (SDNN), and decreased Mean Heart Rate and Physical Stress Index (PSI) levels, with statistical significance (P<0.05). In Frequency Domain Analysis, series of moxa treatments have increased Total Power (TP), Very Low Frequency Oscillation Power (VLF), High Frequency Oscillation Power (HF), normalized HF values while decreasing Low Frequency Oscillation Power (LF), normalized LF and LF/HF ratio with statistical significance (P<0.05). The values of ANS activity, ANS balance, Stress resistance, Stress index, have also shown significant changes. For cardiac stability stroke volume power (SP) and Blood Vessel Tension (BVT) were followed, which were both increased after treatment. All changes were statistically significant (P<0.05). Conclusion : The results have shown a positive correlation between the moxibustion treatments and autonomic nervous system responses on cancer patients through the HRV biofeedback testing. This study suggests possible application of moxibustion treatments for managing ANS functions of cancer patients, although additional studies with larger population are necessary to confirm the data.

This study was designed to examine how dietary protein levels affect organ growth and protein metabolism in early and normally weaned rats. Early and normally weaned rats separated fro the dam on the 15th and 121st day postpartum, respectively. were fed diets containing three levels of protein : low(10%) , normal (20%),and high(40%) . On the 35th day, the weight and DNA, RNA and protein contents in brain , liver, and kidney were determined to ascertain organ and cellular growth. Furthermore, serum total protein , albumin , $\alpha$-amino N and creatine and urinary urea N, and creatinine were determined in order to ascertain protein metabolism and renal functions. Dietary protein levels were not observed to significantly affect total DNA content, which may represent an index of cell number in the liver, brain and kidney. Fresh weight and protein/DNA ratio, which may represent indices of cell size, significantly increased in proportion to dietary protein in the kidney. As for the early weaned rats , the liver cell size significantly decreased. Dietary protein levels and weaning periods did not affect serum total protein and albumin . However, serum urea-N significantly increased in proportion to dietary protein levels whereas serum $\alpha$-amino N was decreased by early weaning . Nitrogen retention was lower in early weaned rats fed low or high levels of protein than in normally weaned rats. The results demonstrate that low or high levels of dietary protein have less desirable effects on protein metabolism in prematurely weaned rats.

PURPOSE: To prevent secondary complications from decreased pulmonary functions and promote neurological recovery, identification of respiratory capacity change patterns depending on different postures of stroke patients and investigation of their properties are needed for active rehabilitation. Therefore, this study was conducted to investigate the changes in vital capacity in response to different positions and to implement the results as clinical data. METHODS: A respiratory function test was administered to 52 patients with stroke in the sitting, supine, paretic side lying, and non-paretic side lying positions. Pulmonary function indexes used for comparison were forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), forced expiratory flow 25-75% (FEF 25-75%), and maximum voluntary ventilation (MVV). One-way repeated ANOVA was used for analysis, and post hoc analysis was conducted using least significant difference (LSD). RESULTS: All pulmonary function indexes were measured in the order of sitting, paretic side lying, supine, and non-paretic side lying positions. Excluding the FEF25-75% and MVV of the supine compared with the paretic side lying position, all other pulmonary function indexes differed significantly (p<.05). CONCLUSION: There are differences in pulmonary function indexes depending on different postures of stroke patients, and the study showed that the non-paretic side lying position yielded the greatest effect on lung ventilation mechanisms. Based on these results, appropriate postures need to be considered during physical therapy interventions for stroke patients.
