Freeze-dried kimchi fractions, water-soluble (WSK) versus water-insoluble (WISK), on their effects on plasma lipids and for their fibrinolytic activities were studied. Nineteen middle-aged healthy subjects were assigned to WSK, WISK, or placebo during 6 weeks of kimchi supplementation. Subjects in the WSK and WISK groups were supplemented with 3 grams of kimchi pills (equivalent to 60 grams of fresh kimchi), while the placebo group was on their normal diets. LDL/HDL and atherogenic index decreased in the subjects who received kimchi pills, but not in those in the placebo group. The levels of plasma triglyceride were significantly decreased in the WSK group compared with those in the WISK group (p<0.05). However, there was no difference in the levels of total cholesterol and HDL between the two groups. Fibrinolytic activity of WISK was significantly higher than that of WSK.

Hypertension is associated with cardiovascular disease. The environmental and genetic factors can cause the development of hypertension. In this study, the relationship between hypertension and family history of hypertension in Koreans was analyzed in consideration of serum fasting blood glucose levels and age. The study subjects were 2,484 subjects who had a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. Hypertension prevalence was 16.4% of all subjects, and subjects with a family history of hypertension were 23.5%. The risk of hypertension was 2.36 times higher in subjects with a family history of hypertension than subjects without a family history of hypertension. In addition, in the subjects with fasting blood glucose levels more than 120 mg/dL, the risk of hypertension was 4.44 times higher in subjects with a family history of hypertension compared with subjects without a family history of hypertension. The relationship between family history and hypertension was slightly higher in the older group than in the younger group. To assess the association between hypertension and family history, further cohort study is necessary in the future.

Objective: The objective of this study was to investigate the effects of Schroth's three-dimensional exercises in combination with respiratory muscle exercise (SERME) on Cobb's angle and functional movement screen (FMS). Design: Randomized controlled trial. Methods: Fifteen subjects with scoliosis were randomly assigned to two groups. Eight subjects were assigned to the experimental group and seven subjects were assigned to the control group. The experimental group underwent SERME using SpiroTiger (Idiag, Switzerland), while the control group performed only the Schroth's three-dimensional exercises (SE). Both groups performed exercises for one hour per day, three times a week for eight weeks. Cobb's angle, pulmonary function (forced vital capacity, forced expiratory volume at one second, and peak expiratory flow) and FMS were measured before and after the experiment. Results: After intervention, the SERME group showed a significant difference in Cobb's angle, FMS scores, and pulmonary function as compared to before intervention (p<0.05). In the SE group, there was a statistically significant difference in Cobb's angle, pulmonary function, and FMS scores compared to before intervention (p<0.05). The SERME group showed a significant difference in Cobb's angle and peak expiratory flow in pulmonary function compared to the SE group (p<0.05). Conclusions: The results suggest that SERME could be a more effective intervention for improvement of the Cobb's angle and pulmonary function for scoliosis patients.

Purpose: We investigated a better method to enhance the vestibular system including balancing by comparing the vestibular stimulation exercise (VSE) and galvanic vestibular stimulation (GVS). Methods: The study was performed with 40 subjects randomized into four groups, including a control group, a VSE group, a GVS group, and a VSE with GVS group. The subjects of VSE performed a forward and backward roll, a right side and left side roll, and an equilibrium board in vestibular stimulation training. GVS was applied for 10 minutes and the cathode and anode side were then changed and GVS was then applied for the remaining 10 minutes. GVS was applied for 20 minutes to the subjects of this group after completion of the VSE program. Results: In the control group, all conditions were significantly decreased (p<0.05) compared to the VSE with GVS group. Also, the center of pressure (CoP) surface was more significantly decreased (p<0.01) and the CoP speed was significantly decreased in the one legged stance (p<0.05) in the control group compared to the GVS group. Conclusion: These findings suggested that GVS training increases balance ability in a narrow width. VSE with GVS training is therefore recommend as the superior method. Using GVS or VSE with GVS training is considered to clinically improve balance ability by stimulating the vestibular system.

Purpose: We investigated the changes in the stop-signal reaction time (SSRT) and the no-signal reaction time (NSRT) following motor sequential learning in the stop-signal task (SST). This study also determined which of the reduction0s of spatial processing time was better between blocked- and random-SST. Methods: Thirty right-handed healthy subjects without a history of neurological dysfunction were recruited. In all subjects, both the SSRT and the NSRT were measured for the SST. Tasks were classified into two categories based on the stop-signal patterns, the blocked-SST practice group and random-SST practice group. All subjects gave written informed consent. Results: In the blocked-SST group, both the SSRT and the NSRT was significantly decreased (p<0.05) but not significantly changed in the random-SST group. In the SSRT and the NSRT, the blocked-SST group was faster than the random-SST group (p<0.05). In the post-test SST after practice of each group, the SSRT was significantly decreased in the random-SST group (p<0.05), but the NSRT showed no significant changes in either group. Conclusion: These findings demonstrate that random-SST practice resulted in a decrease in internal processing times needed for a rapid stop to visual signals, indicating motor skill learning is acquired through improved response selection and inhibition.

The purpose of this study was to identify the effect of mind map activity on scientific attitude and science achievement in elementary school science. The subjects of this study were fifth-grade students selected from two classes in elementary school located in Seoul. The subjects were classified into two groups: One group is composed of thirty-eight students(experimental group) who were participated in mind map activity, and the other is composed of thirty-five students(control group) who were participated in traditional teaching situation. Pretest showed that there were no significant differences between experimental and control group in scientific attitude and science achievement. The results were as follows: First, the experimental group showed a significant improvement in the post-test science achievement compared to the control group. Second, the experimental group showed insignificant improvement in the post-test scientific attitude compared to the control group. Third, female students and mid-ranking group showed a significant improvement in the post-test science achievement. Fourth, in sex and academic ranking, experimental group did not show significant difference in the post-test scientific attitude. In conclusion, mind map activity was more effective than traditional teaching situation on science achievement. But mind map activity was less uneffective than traditional teaching situation on scientific attitude.

The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .

Objective: Elderly people with dementia experience not only cognitive dysfunction but also motor function deficits, such as balance and gait impairments. Recently, transcutaneous electrical nerve stimulation (TENS) has been used to reduce pain as well as to control muscle spasm, spasticity and motor performance in various types of subjects. The purpose of this study determined the effect of a single trial TENS on balance and gait function in elderly people with dementia. Design: A randomized controlled trial. Methods: Twenty-two subjects with dementia were assigned to the TENS group (n=12) and ten subjects were assigned to the control group (n=10) randomly. Subjects were classified into two groups: the TENS group (n=12) and the placebo-TENS group (n=10). The TENS group had electrical stimulation applied on the calf muscle for 15 minutes, while the placebo-TENS group had not received real electrical stimulation. The timed up and go test (TUG) and functional reach test (FRT) were used to measure the balance function, and the 10 meters walk test (MWT) and 6MWT were used to assess gait ability. All tests were performed before and after intervention under a single-blinded condition. Results: After intervention, there were significant improvements in TUG, FRT, 10MWT, and 6MWT results in the TENS group (p<0.05), while the placebo-TENS group did not show significant changes in all outcome measurements. There were also differences in all tests between the two groups at post-measurements (p<0.05). Conclusions: This study demonstrated that a single trial TENS application on the calf may be used to improve balance and gait function in elderly people with dementia.

The purpose of this study was to determine whether neuromuscular electrical stimulation(NMES), applied over the antagonist or the agonist, would alter the H reflex. Attention was focused on the roles of stimulus location. We used normal eight subjects without neuromuscular disease which were divided into 3 groups; the subjects were diveded into group of antagonist, agonist, antagonist-agonist. All groups were meted of eight subjects. Neuromuscular electrical stimulation was administered for 15 minutes. All subjects were subjected to three tests, including a pre-test, post-test and post-20 minute test. The data were analyzed by repeated measures ANOVA and paired t-test. The results were as follows; 1. H latencies were significantly increased in agonist and antagonist-agonist group (p<.01). 2. H/M intervals were significantly increased in agonist and antagonist-agonist group (p<.01). 3. H amplitudes were significantly increased in agonist (p<.001) and antagonist-agonist group (p<.01). 4. H/M ratios were significantly decreased in agonist and antagonist-agonist group (p<.01). In agonist group. H-reflex amplitudes and H/M ratios were more significantly decreased than antagonist group. Future studies will need to determine what influence NMES may have on the excitability of spinal motor neurons in people having UMN syndrome.

The purpose of this study was to compare the dietary status of elderly people according to the degree of obesity and mid-arm circumference in order to provide individualized and efficient nutrition management according to the physical condition of the elderly. Among the total 328 subjects, 72.2% were female, and the mean age and body mass index of the subjects were 76.5 years and $23.4kg/m^2$, respectively. The distribution of obesity degree was 47.9% for the normal group, 23.5% for the overweight group, and 28.7% for the obesity group. The distribution of mid-arm circumference was 18.0% for the under-21 cm group, 37.2% for the 21~22 cm group, and 44.8% for the over-22 cm group. About 82.9% of the subjects were consumed at least three meals a day, and 67.8% of the subjects regularly ate alone. The responses for meal time, regular meal, and meal reduction for 3 months were highest in the 10~20 min. (43.4%), yes (79.3%), and no (58.5%) group, respectively. The responses for eating alone were significantly highest in the overweight group (97.4%), followed by the normal group and obesity group according to the degree of obesity (P<0.05). There were no significant differences in preference for five flavors according to the degree of obesity and mid-arm circumference. Among the dietary habits, 31.1% of all subjects ate milk and dairy products more than once a day, and the response for eating vegetables and fruits more than three times a day was highest in the over-22 cm group (61.9%) while the drinking rate was highest in the under-21 cm group (27.1%; P<0.05). In conclusion, the degree of obesity was related to eating ability, and mid-arm the circumference was related with fruit and vegetable consumption and drinking rate.
