The objective of this study was to analyze the two contrary effects of usage habits on the acceptance of a new IT. The one is a positive one which may be caused by expertise from the repetitive usages of a current system while the other is a negative one which would be due to lock-in. For this purpose, this study suggested three hypotheses which account for not only the negative effect of the habit in current system on the intention of using a new system but also the positive moderation effects on both relationships of perceived usefulness and perceived ease of use with the intention of a new system. For the empirical tests of the hypotheses, this study surveyed acceptance of Google Docs for the users who have a habitual used word processor. The analysis by partial least square approach showed that the hypotheses were statistically supported.

The purpose of this study was to investigate food habits of boy students and to know the difference in food habits between boy and girl students. A previous study had been conducted to girl students in 1998 and this study was carried to boy students in Oct. 2000 using the questionnaires. The subjects were 783 boy students in middle school, high school and university students living in Jeonbuk region. The average score of food habits was $4.09{\pm}1.72$ out of a possible 10(middle school students were $4.96{\pm}1.85$, high school students were $4.17{\pm}1.61$ and university students were $3.15{\pm}1.70$). The average is similar $4.11{\pm}1.63$ to girl students in 1998. The correlation coefficient between the score of food habits and standard of living, present residence, taking nutritional supplements, and sort of school was positive. As a staple food, cooked rice was preferred 95.9% of subjects and this result is similar to girl students of previous study. The most preferred side-dishes was different between girl and boy students. Boy students liked stew the best, but girl students liked Kimchi the best. The most preferred snacks was fruits and fruit juice. The portion of eating cooked rice in boy students (87.8%) was decreased than girl students(90.6%) at breakfast. The main meal to have soup & stew was supper and the most delicious meal was also supper, but primary meal skipped was breakfast. The reasons for skipping breakfast were lack of time(38.7%) and no appetite(17.6%), skipping lunch was missing a time to eat(8.4%), and skipping supper was no appetite(10.5%). Substitution food on no preparation of lunch basket was difference between middle and high school students and university students. Middle and high school students ate noodles and university student ate cooked rice. The preference of snack was that chicken(20.3%) was the best. The time of eating snacks was that anytime(38.6%) was the first, after supper(13.7%) was next. In order to improve the nutritional status of boy students, they must establish good food habits by eating three regular meals per day and balancing their diet. Especially university student must build their regular life style, so they would have three regular meals.

The traditional Korean diet, which is high in rice and vegetables, is fast being replaced by a Western style diet as the standard of living goes up. In addition to this, cigarette smoking has taken on serious proportions, especially amongst those of the younger generation. Because Seoul (and it's surrounding areas) is the hub of Education and Business, it is densely populated and heavily polluted Consequently health-related issues and diseases are starting to resemble those prevalent in Western communities. Historically, stomach cancer was the #1 killer-disease in Korea, but nowadays lung cancer ranks either 1st or 2nd on the list of killer-disease in Korea. This is presumably due to the lethal combination of heavy smoking and pervasive air pollution. Despite these disquieting facts, almost no study had been made of the nutritional patterns and dietary habits of smoking and non-smoking young adults in the Seoul area. Therefore the purpose of this study is to compare the dietary and nutritional patterns of young smokers with those of young non-smokers in and around Seoul. This is done with regards to their eating habits and lifestyles, as well as the dietary components that contribute towards maintaining good health. The results showed that compared to non-smokers, smokers manifested irregular eating patterns and also tended to overindulge on fast- or junk foods. In contrast to this, non-smokers enjoyed a healthier diet, which was high in brown rice, grains, legumes, fresh fruit and vegetables, and 'kimchi'. Amongst the male subjects of this study, it was found that smokers consumed significantly less vitamin $B_2$, calcium, and phosphorous than non-smokers. It was also established that in general, stress-generated smoking habits were formed during the high school years of the younger generation. In conclusion: Because smokers maintain a less healthy diet and life-style, it is to recommended that a 'Health Education Program' be developed which could guide young smokers into adopting better dietary habits and life styles.

The purpose of this study was to investigate food preferences and dietary habits of university students in Kyungbuk province. We assessed anthropometric measurements, food preferences, and dietary habits of seventy nine male and sixty nine female students at K university. The results of this study were analyzed with $\chi$$^2$, t, and ANOVA test using SPSS package program. The percentages of students who were underweight, normal and overweight by body mass index (BMI) were 18.0, 22.1, and 27.7 for males, and 17.8, 21.7, and 28.7 for females, respectively. Preferences for noodles with bean sauce, bread (castella, red-bean bread), beef, pork, chicken, ham, garlic, milk soy bean milt carbonated drink ionic beverages, bun (fried, steamed), croquette, soju(alcohol) and tobacco were higher in males than females, but preferences for tangle, strawberry and orange were lower in males than females. Males did not skip meals compared to females, and ate more meat fat than females. Males exercised more frequently and longer than females. Eighty six point eight percent of females and 69.7% of males were dissatisfied with their weights, and females attempted the weight control more than males. Preferences for bibimbab(boiled rice with assorted mixtures), ionic beverages, and beer were shown higher in overweight males than in normal ones and preference for red fish, hamburger, and chocolate were higher in underweight females than overweight ones. Overweight females skipped meals more and ate more meat fats than normal weight ones. Normal weight males and underweight females were satisfied with their weight. The results of this study suggest that university students need more nutritional education, and modification of dietary habits based on food preference to prevent and treat obesity and to maintain their health.

This study was investigated to examine the dietary habits and satisfaction with a school lunch program for high school boys and girls. The survey was conducted on 416 students(208 boys and 208 girls) using questionnaire. Overall, 40.1% of the respondents reported that they skip breakfast, and more girls skipped breakfast than boys(p<0.05). The major reason for skipping meal was 'no enough time'(48.3%) and duration of meal appeared the highest ratio in '10~15 minutes'(51.7%) and boys having meal with 10 minutes were significantly higher than girls(p<0.001). When asked if they have an unbalanced diet, 58.8% responded "little bit do it but it depends on food". Vegetables were the foods most absent from an unbalanced diet. Additionally, 90% of all respondents takes a snack a day, and 21.5% of the respondents reported that snacks were the most preferable meals. In terms of a satisfaction with school meals, 70.6% of the respondents reported that they were "unsatisfied". Additionally, 43.5% of the students reported that they did not finish their soup. Moreover, 57.5% of the students reported that they were dissatisfied because that food was "not tasty". Based on the results of this study, the meal habits of the students were determined by various factors including gender. To ensure that boys and girls receive the proper nutrition, development of proper eating habits through school meals, nutrition education and a guidance during meal service should be achieved.

The purpose of this study was to obtain basic data for nutrition education of the children in a health promoting elementry school. The data was collected by a questionaire of food habits, and anthropometric measurement and biochemical test in comparison with obesity index. The study subjects were boys and girls aged 10 to 12 years who participated in the “99 Children Nutrition Camp”. The average obesity index was 1.7$\pm$21.6% in boys and -11.4$\pm$12.6% in girls. After school, major leisure items were significnatly different by gender but both boys and girls played mainly computer game. In concern for body image and eating habits, girls had more concern and girls had attempted weight control more than boys. 80.2% of subjects had prejudice for special food, especially, all subjects in the severely underweight group had prejudice. But this tendency was significantly decreased with the increasing obesity index. The lowest preferency was for vegetables(64.4%). The tendency of prejudice of subjects was higher whose mother are thirties than those of subjects whose mother are in fourties. The serum GOT and GPT values were significantly higher in overweight and obese group than the other groups. The only serum T-chol was significantly higher in boys than in girls. The number of risk factors related to coronary heart disease(CHD) based on coresponding criteria of TG, T-chol, HDL-chol, and LDL-chol was not increased significantly with the degree of obesity index. The results indicated the need of nutritional management for the children. At a point of view, to educate children early who are able to change food habits and life-styles means to help heathy growth and to deliver up heathy adults. Active nutrition education for both children and mothers will be recommended with joint participation of nutritionists in community public health center and elementary school.

The purpose of this study was to investigate the difference of body composition, eating habits and dietary intake in three Sasang constitutions. This survey was carried out using anthropometry, a questionnaire about eating habits, and 24-hour recall of dietary intake on 45 male and 29 female students of the fifth grade at C elementary school. The results are summarized as follows: A total of 44.6% of the subjects were Taeumin, 35.1% were Soyangin, and 20.3% were Soeumin. The average weight, WHR, Triceps, Rhrer index and BMI in the Taeumin group were significantly higher than those of the Soeumin and Soyangin groups. The body fat mass (kg) and abdominal fat (%) in the Taeumin group were significantly higher than those of the Soeumin and Soyangin groups. The soft body mass (%) in the Soeumin group was significantly higher than that of the Soeumi and Soyangin groups. The Taeumin’s energy expenditure in physical activities was little high than that of the Soyangin and Soeumin groups, but the Soyangin’s energy expenditure in physical activities per weight was a little higher than that of the Taeumin and Soeumin groups. The calorie and most of the nutrient intake were lower than those of Korean RDA. In the case of males, most nutrient intake, except for fiber, carotene and vitamin C were high in the Taeumin. For females, most nutrient intake, except for calcium and retinol were significantly higher in the Taeumin group. Conclusively, anthropometry characteristics, body composition, energy expenditure in physical activities, eating habits and dietary intake are different among the three Sasang constitutions. This study suggests the possibility of using Sasang consitutions as a basis for providing nutritional education and health guidelines.
