This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The results are as follows: 1. It is necessary to improve the appraisal system for how radiation environmental impact assessment in the preparatory stage, when the nuclear power plant is under construction. The administrative agency should take the charge of making out the evaluation of the influence of radiation and be able to gather not only the opinions of civil environmental entities. It should read just system to observe the content of the environmental impact assessment. 2. Of course the neighboring residents are at odds with the mobilized construction crew due to the bad effects of noise, vibration, dust and so on during construction and they are concerned about their health due to accumulated bad effect. Consequently, we need to analyze whether we should keep to a strict the level of radiation discharge or not. 3. The atomic waste does not come under the rule of waste countrol but of atomic energy control. Due to the insufficiency of regulations about the safty of atomic waste and proper management, it is necessary to have stricter atomic waste control administration. 4. There are no regulations on heat pollution under our environmental law at this time. Therefore, we need legislation about heat pollution incruding the matter of discharge water from an nuclear power plant. 5. Countermeasure are necessary for closed-down nuclear reactors. Technical know-how concerning this is not sufficient on the international level. Related legislation is also need.

The purpose of this study was to determine the effect of 12-week exercise program on isokinetic muscular strength and endurance in the elderly women(n=32, age=66.78±4.01). They were tested on their muscular strength and endurance at the beginning and at the end of the 12-weeks study(pre-post tests). Muscle strength was evaluated by peak torque of the knee extensor and flexors at 60 deg/sec(5 repetitions) and Endurance was assessed by total work of the knee extensor and flexors at 120 deg/sec(15 repetions) using isokinetic exercise machine(Biodex system II, U.S.A.). For data analysis, Mean and Standard Deviation scores were calculated, and paird t-test was used. This study resulted in as follow; First, after 12-week exercise program, muscular strength of right and left knee flexors was significantly improved. Second, after 12-week exercise program, endurance of right and left knew flexors was significantly improved. In conclusion, regular exercise delays decline of muscular strength and endurance or improves muscular strength and endurance in elerly. It will have an effect on essential life of elderly, improve quality of life.

One- to three- month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously^(7)), weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3 month, significantly. Here, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 ㎜, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month, that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 ㎜ at 1 to 3 postpartum months, respectively. The upper arm circumference of infants were 11.7, 13.4, 14.3㎝, and the arm muscle diameter were 34.5, 39.3 and 41.7㎝ at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months. Overall, there were no significant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infants showed bigger significantly in arm circumference than the breast-feds. From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.

In this paper, we adapted BLDC motor to PV water pumping systems to maintain high efficiency in the wide speed area. Also to design confidence, we adapted the vector control that drive the maximum torque at each speed limit. We designed optimal gain value of current, speed and pressure PI controller. Inverter gate pulse used Space Vector PWM to reduce torque pulsation of BLDC motor. Finally it was improve general matters of high water storage tank method by direct water supply pumping method.
