The purpose of this study was to investigate the eating behavior and life habits of kindergarten children 5 to 7 years old in Chuncheon area. This study was conducted in December, 1996. Anthropometric indices(height, weight, skinfold thickness, mid-arm circumference) were measured and body mass index(BMI), Rohrer index, arm fat area were calculated to estimate children’s body fatness. Also the eating behavior and life habits were determined tv using questionnaire method. The results were as follows: Body fat rate of the children was almost normal according to Rohrer index and BMI. There was significant difference in birth weight between male and female. The problems of the eating behavior were frequent skipping breakfast and eating-out. The rate of the children who took snacks 2 times a day was 46.9％. Most children tended to take sweet snacks such as ice-cream, chocolates, cookies, and they tended to prefer meats and fishes to vegetables. The rate of breast feeding was 28.3％ and the rate of weaning foods prepared at home was 61.1%. Many children preferred indoor activities such as watching TV, toy furniture play, building block to outdoor activities such as roller-skating, cycling, jogging in their spare time. The rate of the children who took exercise regularly was 15％. Children tended to eat kimbap, fried chicken, ramyeon more frequently in various instant foods. The intake rates of fruit juice and barly tea were relatively high and children's favorite fruits were watermelon and mandarin orange. From this results, skipping breakfast, frequent eating-out and the monotony of food preference appears to cause imbalance in nutrient intakes of the children and to have bad influence on children’s health. Accodgingiy, the comprehensive nutrition education and proper modification program should be needed for the children and their parents to correct the eating behavior and life habits. The reasonable exercise programs are needed to motivate outdoor activities of the children, and the importance of breast feeding and weaning foods should be emphasized to lactating women and pregnant women.

협업 지원을 위한 기존의 시스템은 일반 기업의 범용적인 업무 프로세스에 초점을 두고 있어 중소 산업 디자인 회사와 같이 소규모의 특화된 업무프로세스를 가지는 기업에는 적용이 용이하지 않다. 본 논문에서는 중소 산업 디자인 기업의 업무 프로세스를 분석하여 협업을 개선시키기 위한 요구 조건들을 도출하고, 이들 요구 조건들을 체계적으로 반영하기 위하여 고객의 승인과 내부의 일정 공유 기능에 중점을 둔 협업 지원 시스템 플랫폼을 제안한다. 제안된 협업 지원 시스템은 내부 조직원 중심의 비체계적 협업지원의 기능이 아닌 외부 조직원과의 체계적 협업을 지원한다는 면에서, 협업 지원 시스템의 새로운 연구방향을 제시하고 있으며. 상대적으로 정보 시스템의 도입이 취약한 중소산업 디자인 회사의 협업 지원 환경을 개선하고 프로젝트를 체계적으로 진행하는데 기여할 수 있을 것으로 예상된다.

This study examines whether the reinforcement theory would be effectively applied to teaching assistant robots between a robot and a student in the same way as it is applied to teaching methods between a teacher and a student. Participants interact with a teaching assistant robot in a 3 (types of robots: positive reinforcement vs. negative reinforcement vs. both reinforcements) by 2 (types of participants: honor students vs. backward students), within-subject experiment. Three different types of robots, such as 'Ching-chan-ee' which gives 'positive reinforcement', 'Um-bul-ee' which gives 'negative reinforcement', and 'Sang-bul-ee' which gives both 'positive and negative reinforcement' are designed based on the reinforcement theory and the token reinforcement system. Participants' task performance and reaction rate are measured according to the types of robots and the types of participants. In task performance, the negative reinforcement robot is more effective than the other two types, but regarding the number of stimulus, the less the stimulus is, the more effective the task performance is. Also, participants showed the highest reaction rate on the negative reinforcement robot which implies that the negative reinforcement robot is most effective to motivate students. The findings demonstrate that the participants perceive the teaching assistant robot not as a toy but as a teaching assistant and the reinforcement interaction is important and effective for teaching assistant robots to motivate students. The results of this study can be implicated as an effective guideline to interaction design of teaching assistant robots.

Objective: This study evaluated the cytotoxicity and genotoxicity of fixed orthodontic treatment with three different light-cured orthodontic bonding composites by analyzing micronucleus (MN) formation in the buccal mucosa during a 6-month period. Methods: Thirty healthy volunteers were selected from consecutive patients referred for orthodontic treatment. Equilibrium 2 brackets and molar tubes (Dentaurum) were bonded with three different lightcured orthodontic bonding composites-Transbond XT (3M Unitek), Kurasper F (Kuraray Europe), or GrenGloo (Ormco Corporation)- to all teeth in both arches. Exfoliated buccal epithelial cells were scraped from the middle part of the inner cheeks with sterile cement spatulas before treatment and at 1, 3, and 6 months after treatment. MNs and nuclear alterations, such as karyorrhexis (KR), karyolysis (KL), and binucleated cells (BNs), were scored under a light microscope. Repeated measure ANOVA was used to calculate statistical differences in degenerative nuclear abnormalities. Results: MN rates did not significantly differ among different time points within the same cell type (p > 0.05). In contrast, the number of BNs in buccal epithelial cells significantly increased in all composite groups (p < 0.01, Transbond XT; p < 0.001, Kurasper F and GrenGloo). KL frequency significantly increased between the beginning and end of the study in the Kurasfer F ($0.80{\pm}0.79$ to $1.90{\pm}1.10$; p < 0.05) and GrenGloo ($1.30{\pm}1.06$ to $2.40{\pm}1.08$; p < 0.05) groups. Conclusions: After 6 months of fixed orthodontic treatment with different light-cured composites, morphological signs of cytotoxicity were observed but genotoxic effects were absent.

The purpose of this study was to investigate the dietary life about Kimchi of the housewives. Self-administrated questionnaires were completed by 322 housewives in Wonju area. The results were as follows: In the point of housewives' domestic duties, over 50% of housewives took care of their domestic duties alone, and the rate who learned how to manage domestic duties from their mothers before marriage decreased as the age got younger. 77.6% of housewives responded that both man and woman could manage a dietary life at home in the future, and the rate of such response was higher as their educational careers were higher and they were younger. In the point of housewives' basic situation about Kimchi, the rate of housewives who knew how to prepare kimchi was high as they were older, and the holding rate of a refrigerator for Kimchi was high as much as 72.4%. In the point of preparation for Kimchi, the rate who made Kimchi by themselves was high, but the rate of preparing Kimchi by their parents for them was higher in the twenties. Frequency of making Kimchi, an amount or a kind of Kimchi were notably different according to housewives' age, a type of their family, the number of their family, and their having a job or not. Housewives' opinion of a market kimchi was that it was expensive, and not sanitary, and rate of purchasing Kimchi was also low. In the point of the prepartion method of Kimchi for the winter, the rate who gained Kimchi from their parents was higher as they lived in an apartment, and had a nuclear family, and had the lesser family members. In an amount of Kimchi prepared for the winter, 11∼22 heads were 23.9% and 21∼30 heads were 21.9%. In the point of the method preparing Kimchi in the future, 53.8% of housewives responded that they would make by themselves, and 28.0% answered they would prepare or purchase. 77.4% of housewives answered that they would teach how to make Kimchi to their children.
