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.

BRS는 인간의 잠재능력을 적극적으로 계발 · 활용하여 임의의 시료에 대한 미지 (未知)의 생체정보 (Bio-Information)를 편리하게 분석할 수 있는 효과적이고 경제적인 분석장비이다. 그러나 BRS와 관련된 분석방법 자체의 정확도에 대한 연구는 충분하게 이루어지지 않고 있다. 그래서 BRS 분석방법의 정확도를 과학적으로 확인해보기 위해서 본 연구를 진행했다 실험결과, BRS에 의한 생체정보 분석방법 의 정확도는 측정자의 숙련정도에 따라 다르지만 고급 측정자의 경우에는 95% 이상의 높은 확률로 표준시료의 생체정보를 정확하게 분석할 수 있으며, 측정자의 분석능력이 떨어지는 경우에는 여러 명의 측 정자를 대상으로 비교검토(Cross-Check) 방식으로 실험을 보완하면 90% 이상의 정확도를 확보할 수 있었다. BRS is a sort of analysis-instrument which help to estimate some Bio-Information for a sample conveniently and effectively But, for lack of the study to verify the confidence-degree of the Bio-Information analysis method related to BRS, the availability of the method is not known clearly yet, It was the reason that made authors perform this study And It was possible to arrive at the following two conclusions I though the confidence-degree of the Bio-Information analysis method ny BRS was different according to the degree of the expertness of a person using the instrument in the case of the very skillful expert, the confidence-degree for the standard sample used in this study was reached to 95% up 2 In the general case, to improve of the confidence-degree of the Bio-Information analysis method by BRS, the cross-check method by the several measuring person can be introduced.

This study was designed to investigate the difference of teeth and craniofacial complex between normal occlusion and Angle's Class II, div. 1 malocclusion in korean childern. The sample was divided into 2 groups, the 66 subjects with normal occlusion and 96 subjects with Angle's Class II, div.1 malocclusion in both sexes. The results obtained were as follows: 1. No significant differences were observed in ant. cranial base length & flexure(saddle angle) between normal occlusion & cranial Angle's Class II, div. 1 malocclusion group, but posterior cranial base length of Class II, div. 1 malocclusion group was larger than that of normal occlusion group. 2. No significant difference was observed in the anteroposterior position of Maxilla to cranial base between two groups, but mandibular position in Class II. div. 1 malocclusion was posterior and interior to that of normal occlusion. 3. The length of maxilla (ANS-PSN) was larger in Class II, div. 1 malocclusion than normal occlusion. The length of mandibular body(Go-Me) was nor differnet between Class II, div. 1 malocclusion and normal occlusion. 4. Maxillary incisor position of Class II, div. 1 malocclusion to cranial base was more protrusive than that of normal occlusion, but there was no difference in mandibular incisor position between two groups.

This study was conduced to evaluate the efficacy of indeloxaziine hydrochloride(Elen) on chronic stage of cerebrovascular diseases(CVD). Total 38 patients with chronic stage of CVD(over 1 year history of CVD), 19 cerebral infarction and 19 cerebral hemorrhage, were given indeloxazine hydrochloride 20mg 3 times daily for over 3 months(3-6mos). The efficacy of the drug was evaluated by itemized neurological check lists in each month period. The results were summarized as follows. 1. There was significant improvement of spontaneity and emotional problems in each subsequent month after indeloxazine hydrochloride administration in a group of cerebral infarction. 2. There was also significant improvement of spontaneity, abnormal behaviors and emotional problems in each subsequent month after drug adminstration in a group of cerebral hemorrhage. 4. The drug was safe but rarely pruritic skin rashes and mild gastrointestinal disturbance were observed as adverse reactions.

Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 'Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 °Brix of the dandelion concentration) resulted in better textural properties and s ensnry scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice roated with 20 °Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 °Brix and 5% respectively, in proportion to the total weight of raw rice.

The electrical and optical properties of rf-glow discharge produced hydrogenerated amorphous semi-conductor silicon (a-Si:H) films have been studied as a function of gas flow ratio of dopant at a substrate temperature (Ts-RT, 250℃). In order to determine the electrical, optical properties, conductivity, optical absorption coefficients and hydrogen content are measured. The I-V characteristic of Mo/p-n diode in the dark and the J-V characteristic of ITO/p-i-n under illumination are measured as a application of a-Si:H.

Centrifuge model tests were performed to find appropriate equations proposed previously of estimating the bearing capacity of the composite clayey soil reinforced with sand compaction pile. Model tests were carried out with changing the replacement ratio of SCP (20%, 40%, 70%), contents of fine materials (5%, 10%, 15%) and ratio of treated width to loading width (1B, 2B, 3B). Test results about bearing capacity of the composite ground were obtained by performing the surcharge load tests with measurements of applied loads and vertical displacement. Bearing capacities against bulging and shear failures were estimated by the existing equations. As results of comparing the estimated bearing capacity with experimental values the bearing capacities estimated by Greenwood's equation (1970) for bulging failure mode were similar to the test results.

태양광 발전시스템을 위한 계통 연계형 PWM 인버터의 변조지연 보상

Since the residential load is an AC load, while the output of solar cell is a DC power, the photovoltaic system needs the DC/AC converter to utilize solar cell and must provide the sinusoidal wave current and voltage, at unity power factor in the case of driving to interact with utility line. PWM modulator must do stable modulation even though it contains the disturbance like a distortion and noise, and it needs compensation method, because there is a timing interval between sampling points and carrier waves, while the synchronous signal is controlled by the micro processor. In this paper, we maximaze output of solar cells which is propotional to variation of insolation, using single phase PWM voltage source inverter, and we can drive in high power factor with utility line by control and compensation method which is concerned with synchronous signal distortion and modulation delay, using low pass filter and phase shifter.
