  • This study was done to compare the effects of managing obesity using a behavior modification program and an aerobic exercise in adolescent girls. Thirty three subjects were selected from one girls' middle school located in Seoul. Seventeen girls participated in the behavior modification program by joining 60-90 minute group sessions weekly. The aerobic exercise program was given to 16 girls three times per week for 60 minutes each. These iterventions continued for eight weeks from October 17 to December 10, 1995. The data were obtained before and after the interventions by measuring degree of obesity, body weight, blood pressure, serum lipid, %body fat, and waist to hip ratio(WHR). Data ware analysed by using paired t-test. The results are as follows. 1. Subjects in both the behavior modification and the aerobic exercise groups showed significant decrese in the degree of obesity, body weight, diastolic blood pressure, total cholesterol, low density lipoprotein, %body fat and fat mass after the 8-week interventions. 2. Systolic bood pressure, high density lipoprotein cholesterol and waist to hip ratio were significantly decreased after the 8-week intervention in the behavior modification program group while triglyceride was significantly decreased after the 8-week intervention in the aerobic exercise program group. These findings indicate that both behavior modification and aerobic exercise programs are good strategies for managing obesity among adolescent girls.

  • It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.

  • Purpose: This study was performed to investigate effects of behavior modification on obesity index, skinfold thickness, body fat, serum lipids, serum leptin in obese elementary school children. Method: Forty seven students were selected from two elementary schools. Twenty four children in one school were assigned to experimental group and twenty three children in another school were assigned to control group. Experimental group was received 60~70 minutes of behavior modification once a week for 8 weeks. Result: Obesity index of the experimental group was significantly decreased after behavior modification. But there was no significant difference between two groups. The increase of skin fold thickness was significantly low in the experimental group compared to the control group. Percentage of body fat and fat mass were significantly decreased in the experimental group. Fat free mass was significantly increased in the experimental group. HDL-C, triglyceride and serum leptin between the experimental group and control group showed no significant difference. Conclusion: These results indicate that behavior modification is effective in decreasing percentage of body fat and fat mass, in less increasing skinfold thickness and in increasing fat free mass. In conclusion, behavior modification can be used as effective strategy for managing obesity in elementary school children.

  • The vibration and noise of gears is due to the vibration exciting force caused by the tooth stiffness which changes periodically as the mesh of teeth proceeds and by the transmission error, that is, the rotation delay between driving gear and driven gear caused by manufacturing error and alignment error in assembly and so on. The purpose of this study is to develop how to calculate simultaneously the optimum amounts of tooth profile modification, end relief and crowning by minimizing the vibration exciting force of helical gears. We estimate the vibration exciting force by the mesh analysis of gears. The constraints of this problem consist of contact ratio and strengths of gear teeth such as tooth fillet stress, surface durability and scoring. ADS(Automated Design Synthesis) is used as an optimization tool. And, since the aspect ratio is an important parameter of tooth modification, we investigate the relation between it and the optimum values of tooth modification. The proposed method can calculate the optimum amount of tooth modification automatically and is to be utilized to resolve the problem of vibration of helical gears.

  • This study suggests the general support center with comprehensive services for the elderly. In general, the modifications of the elderly housing have a direct influence on the "Quality of life" and "Aging in place" for the elderly. But until now, the elderly housing modification has been carried out separately on the elderly welfare category. It is very inefficient and inconvenient for the elderly. Therefore, it is necessary to have a comprehensive organization that includes the implementation of modifications. To provide reasons for this insistence, this study analyzed the previous research, legal system guidelines, and others related things. And it researched the perception of the comprehensive institution and the need for housing modification through the recognition survey of the elderly and the early elderly. The study found that the current domestic legal system does not have an integrated system to carry out the entire process of applying and implementing the elderly housing modification. On the other hand, the results of the survey showed that the elderly hoped to introduce a comprehensive and user-friendly institution for housing modification.

  • The inhibitory effect of dl-puerol A as but-2-enolide isolated from Sophora japonica was investigated on copper ion-induced protein oxidative modification in vitro. It inhibited copper-induced protein oxidative modification. However, its inhibitory effect was a little weaker than that of $dl-{\alpha}-tocopherol$ as an antioxidant. The results demonstrated that dl-puerol A, one of but-2-enolides, might be of use in the oxidative stress.

  • Diabetes mellitus is reaching epidemic proportions worldwide. The insufficiency of medication to cope with this burden has coincided with a dramatic rise in the prevalence of use of complementary and alternative therapies, especially herbal treatments. This surge in demand presents a challenge to prove the safety and efficacy of these treatments in diabetes. Korean red ginseng (steam treated Panax ginseng C.A. Meyer) is a strong candidate to succeed. It has been shown to possess a multitude of hypoglycemic effects and improve metabolic disturbances related to diabetes in in vitro and animal models. Data in humans is also emerging to support these benefits. Whether these results can be replicated in a rigorous clinical testing program is unclear. We therefore investigated the antidiabetic effects of Korean red ginseng in a series of 2 acute and 1 longterm randomized, double-blinded, placebo-controlled clinical trials. This paper provides the rationale for this program of study, expanding on the problem of diabetes, its management, and the possible role for Korean red ginseng. It then describes the design and expected findings.
