This research was designed to compare the subjective evaluation of texture image and preference by structure and sensible characteristics of women's suits fabrics between on- and off-line. 78 subjects who majored in fashion design evaluated the sensibility image and preference of 15 various kinds of specimens on- and off-line. Factor analysis, t-test, Pearson correlation and regression were used for a statistical analysis by SPSS WIN 13.0. The results of this study were as follows: 1. Women's suits fabrics were classified according to five sensibility image factors: 'classic', 'sophisticated', 'natural', 'characteristic', and 'practical'. 2. The results of the t-test showed that there were no differences between the on- and off-line evaluation of sensibility images. 3. The analysis of correlation indicated that the 'classic'-'sophisticated' and 'natural'- 'practical' sensibility images show a significant correlation between the two kinds of evaluation. 4. The results of regression revealed that 'sophisticated', 'characteristic' and 'practical' sensibility images had an effect on the purchase preference of women's suits fabrics. 5. 'Sophisticated', 'characteristic' and 'classic' sensibility images had an effect on the tactile preference of women's suits fabrics. 6. The structural characteristics of fabrics: thickness, weave and weight had an effect on the 'classic' sensibility image. Thickness had an effect on the 'sophisticated' sensibility image and fabric count had an effect on the 'characteristic' sensibility image.

The assessment of hand of the denim fabrics finished by enzymatic hydrolysis will be discussed in this study. The subjective hand and the preference of the denim fabrics finished by enzymatic hydrolysis were evaluated using the developed scale(Part I). The factors affecting consumer's taste for denim fabrics were analyzed by statistics using SAS program. Also, the enzymatic of hydrolysis on the properties of denim fabrics were evaluated by subjective hand measurements. The results are as follows; Regarding the surface properties and the weight, Tencel was evaluated to be the finest, the smoothest, the most flexible, the warmest, the most refined, the sleekest, the flossiest, the lightest the softest, and the thinnest among the four kinds of fabrics. The other fabrics in the order of cotton/Tencel, cotton, cotton/PP were evaluated to qualify the listed touches. Tencel was evaluated to be the loosest and the weakest among the four kinds of denim. Cotton was evaluated to have the driest touch. In addition, the fabrics were evaluated to be more elastic and less wrinkly in the order of Tencel > cotton > cotton/Tencel > cotton/ PP. For the hand preference, the fabrics were ranked in the order of Tencel, cotton, cotton/Tencel, cotton/PP, where tencel is the moat preferred. Cotton/Tencel and cotton/PP showed negative values in the hand and the color preference, meaning that the evaluators disliked their touches. Hand preference of enzyme hydrolyzed cotton/Tencel and cotton/PP denims do not seem to appeal to Korean people.

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.

The anti-obesity effects of yeast hydrolysate (YH) supplementation (1.0 g/d) have already been demonstrated. We investigated whether a low dose of YH (0.5 g/d, YH-500) also has the anti-obesity effects. Thirty obese women were randomly assigned to the control or YH-500 groups. After 8 weeks, weight and body mass index were significantly reduced by the YH treatment (0.5 g/d) (P<0.05). The YH-500 group lost a significant amount of body fat after the 8-week treatment: fat mass 25.9 kg (baseline) versus 23.8 kg (8th week), P<0.01; fat mass ratio 38.8% (baseline) versus 36.5% (8th week), P<0.05. The YH-500 group showed a significant reduction in calorie intake during the 8-week treatment (P<0.001). The control group wanted to eat much more food (P<0.05) and sometimes thought about eating more often compared with the YH-500 group (P<0.05). Whereas the control group showed a slightly increased sweet preference, the YH-500 group showed a significant reduction in sweet preference (P<0.05). In conclusion, low dose YH supplementation (0.5 g/d) may induce a reductions in weight and body fat in obese women via the reduction of calorie intake.

In Electronic Commerce, the latest most of the personalized recommender systems have applied to the collaborative filtering technique. This method calculates the weight of similarity among users who have a similar preference degree in order to predict and recommend the item which hits to propensity of users. In this case, we commonly use Pearson Correlation Coefficient. However, this method is feasible to calculate a correlation if only there are the items that two users evaluated a preference degree in common. Accordingly, the accuracy of prediction falls. The weight of similarity can affect not only the case which predicts the item which hits to propensity of users, but also the performance of the personalized recommender system. In this study, we verify the improvement of the prediction accuracy through an experiment after observing the rule of the weight of similarity applying Vector similarity, Entropy, Inverse user frequency, and Default voting of Information Retrieval field. The result shows that the method combining the weight of similarity using the Entropy with Default voting got the most efficient performance.

This study was carried out to develop a computerized menu planning for athletes who need weight control. The outine of the computer lprogram for menu planing that was developed in this study are as follows: First of all, the athlete's weight to be lost/controlled, age, sex and quantity of daily activity were put into the computer. When an individual file was formed, an ordered menu formulated to control the necessary quantity of nutrients were sufficient. The software is planned according to the sturcture of the menu which can be chosen at random. Also, it was made possible to change the menu according to one's preference. Therefore, this was similar to the manmachine system which is desirable form in using the computer. The developed software could be used not only for athletes but also for a nutrition councelling program for those who need weight control.

This study was undertaken to assess eating habits of 230 rural elementary school students living in ChunNam province. Anthropometric data showed that their mean height of girl students was significantly higher than that of boy students. Irregular eating pattern of girl students was noted. There was a significant difference in concerning on weight control between girls and boys. Girls especially view themselves as too obese even though their weight was in normal range and they were more concerned on weight control due to appearance. Nutrition education at school was an important factor ruling out peaky eating habits in participants. More effective nutrition education might be suggested to form a good eating habit which result in maintenance of ideal weight and promote health for rural elementary school students.

The study investigated the eating lifestyles of female consumers and whether they influenced weight control behavior. The findings of the study can be summarized as follows. First, the eating lifestyles of the subjects were presented four types: 'active eating life pursuit type', 'safe economical type', 'gourmet type' and 'passive negligence type'. In general, most cases were of the 'passive negligence type'. Second, weight control behavior was analyzed according to eating lifestyle. The results of the analysis indicated that the female consumers of the 'active eating life pursuit type' and 'safe economy type' had high behavior levels in each aspect of weight control attitude, subjective regulation, perceived behavior control, and behavior intention. Third, the 'gourmet type', with a strong preference for taste, and the 'passive negligence type', with fewer eating considerations in general, showed weaker attitudes towards weight control and the recognition of pressure from people around them. As such, the level of consideration for food or eating was correlated with weight control. These findings impliedy that the more active, safer, and economical women are in their general eating style, the stronger they perceive weight control issues.

The objective of this research was to study the differences between urban and rural areas high school students in body image and dietary habits. The number of subjects in Seoul and Kyungkido were 902. Based on self-reported height and weight, there was no significant difference between the urban and rural students. However, the rate of obesity was significantly higher in males, whereas the rate of underweight was significantly higher in females, especially for urban females (p < 0.05). Their ideal body image ratio as skinny or slender-type was 91.6% (urban) and 95.7% (rural) for male category while 100% (urban) and 99.4% (rural) for females. Urban females had a strong preference for a skinny body (p < 0.05). Rural students were more highly interested in weight control than urban students were, but they appeared not to care their health. In addition, they had significantly lower levels of weight control knowledge and dietary attitude score (p < 0.001). Subjective assessment of body weight appeared to be more important in terms of body satisfaction, weight control knowledge and dietary attitude than actual measurement of body mass index. Significant test revealed that weight control knowledge was related to dietary attitude (p < 0.01). (p < 0.01).
