This study was done to investigate the relationship between the perception of body image, body weight satisfaction or dietary behavior and self-rated health status in Korean college students. Subjects, 285 college students, were divided into three groups (healthy, normal, and unhealthy) according to the answer for the self-rated health question. Information about demographic status, self-rated health condition, height and weight, perception of body image, satisfaction of body weight, concern for body weight control, dietary behavior, nutritional knowledge, and health-related characteristics collected by a self-reported questionnaire. The proportion of men and women in each group was not significantly different. The academic year, major, experience of nutritional education, and type of residence were not significantly related with self-rated health but the pocket money range was significantly associated (p<0.05) with self-rated health. The proportion of subjects rated their health as unhealthy was the lowest in 210-300 thousand won pocket money range and was increased in less than 210 thousand won or over 300 thousand won pocket money ranges. There were no significant differences for age, height, weight and BMI between the groups. The body image perception and body weight satisfaction levels of healthy group was significantly higher than those of unhealthy group (p<0.01 and p<0.001, respectively), but the level of concern for body weigh1 control in healthy subjects was significantly lower than that in unhealthy subjects (p<0.05). The proportion of subjects reported as healthy was significantly increased with increased frequencies of following food behaviors; weekly use of protein foods (p<0.01), vegetables (p<0.05) and dairy products (p<0.01), and food habits such as "regularity of meal time" (p<0.01), "eating in moderation" (p<0.05), and "eating breakfast" (p<0.001). Overall results suggested that the college students have tended to have a better perception of health when they have better body image perception, body weight satisfaction and dietary behaviors.

The purpose of this study was to implement and evaluate the nutrition education program for elementary school children Subjects were 5th graders (n = 142) of an elementary school in Seoul, and 138 children completed four sessions of nutrition education during March-April, 2008. One group pretest-posttest design was used to evaluate the program effectiveness. Anthropometric measurements and measurements on nutrition knowledge, eating attitudes and eating behavior were done before and after education. Data were analyzed using paired t-test, t-test and ${\chi}^2-test$. After completing nutrition education, body mass index (from 19.3 to 18.9), fat mass (from 10.9 kg to 10.1 kg), percent body fat (from 25% to 23.3%) of subjects decreased significantly (p < 0.001). Percentages of overweight or obese children were 24.6% at pretest and decreased to 20.3% at posttest, although it did not reach statistical significance. Total score of nutrition knowledge increased significantly from 11.9 (59.5/100) at pretest to 14.7 (73.5/100) at posttest (p < 0.001). After nutrition education, percentages of correct answers increased significantly in 10 knowledge items out of 20 items. These included items such as desirable weight control, energy requirements for boys, food groups, snack, and function of fat and balanced meals (p < 0.001). Total score of eating attitudes increased significantly from 35.1 to 36.9 (p < 0.001). Attitude of applying nutrition knowledge to daily life (p < 0.001), interest toward nutrition and health (p < 0.001), attitude of moderating food intake (p < 0.01), and attitude toward eating habit and future health (p < 0.05) were significantly different between pretest and posttest. Total score of eating behaviors increased significantly from 46.7 (possible score: 20-60) to 49.5 by nutrition education (p < 0.001). Improvement in eight eating behaviors were noticed after nutrition education. These included eating meals slowly, eat protein foods (p < 0.001), eating breakfast, eating meals regularly, eating meals with diverse foods, having dairy foods, eating foods using plant oils (p < 0.01), and having grains (p < 0.05). Subjects evaluated quite positively in attractiveness of program, understanding of program contents, helpfulness of program in improving nutrition knowledge and meal management. Study results show that the nutrition education program was effective in improving nutrition knowledge, eating attitudes and changing eating behaviors of children. This program can be used in nutrition education of children at school or at public health centers.

Purpose: The purpose of this study is to examine the relationship among body image, depression and sexual function in Korean postmenopausal women. Methods: Subjects were 96 postmenopausal women who have lived in Korea. Data was collected using Semantic Differential scale, CES-D, and FSFI. Results: The level of body image was positive, depression was mild, and sexual function was moderate. There were no significant correlation between depression and sexual function. The subjects who had more positive body image experienced higher sexual function and less depressed mood. Conclusion: These findings showed the need for a knowledge development program for nurses regarding women's sexual function. Also, nurses must do counseling with sexual partner's and consider patients' body image when counseling those who complain of sexual dysfunction.

Even though the impact of manufacturing quality to reliability is not considered much as well as that of design area, a major cause of an early failure of the product is known as manufacturing problem. This research applies two different types of neural network algorithms, the Back propagation (BP) algorithm and Learning Vector Quantization (LVQ) algorithm, to identify and classify the nonrandom variation pattern on the control chart based on knowledge-based diagnosis of dimensional variation. The performance and efficiency of both algorithms are evaluated to choose the better pattern recognition system for auto body assembly process. To analyze hundred percent of the data obtained by Optical Coordinate Measurement Machine (OCMM), this research considers an application in which individual observations rather than subsample means are used. A case study for analysis of OCMM data in underbody assembly process is presented to demonstrate the proposed knowledge-based pattern recognition system.

The purpose of the paper is empirically to explore 'design manner', focusing on the designer's knowledge boundary on the designer-user interactions in the design process. This study conducts a field study and observed designer's interactions with actual users in a leading user-centered design firm over three months. The observations revealed how designers bring ideas about users into design without physically interacting with users during the design process. Based on Bourdieu's theory of practice and the concept of boundary objects, this study introduces the concept of 'design manner', by which designers incorporate user's ideas into the design process without actual involvement of users in the process. This paper contributes to the body of knowledge by introducing the design manner in-between designer's and user's knowledge boundaries and argue bridge between theoretical and actual designer-user interactions in the IS design process.

Objectives: This study was performed to examine dietary habits, life stress, and nutrition knowledge among high school students in Gyeonggi area. Methods: A total of 431 high school students (210 males, 221 females) in Gyeonggi area participated in this study from November to December of 2011. The study was a questionnaire-based survey that included dietary habits, dietary attitudes, life stress, and nutrition knowledge. Results: Body weight, height, and body mass index were all higher in male students than in female students (P < 0.001, respectively). For dietary habits, the average score (P < 0.01) and scores for considering combination of food groups (P < 0.05), eating green and orange vegetables (P < 0.05), eating meat, fish, eggs, or beans everyday (P < 0.05), drinking milk (P < 0.001), and eating seaweed (P < 0.01) were higher in male students than in female students. For dietary attitudes, the average score (P < 0.05) and scores for the five items were significantly different between male and female students. Male students showed a significantly lower nutrition knowledge score than female students (P < 0.05). Life stress score of students largely was attributable to academic factors, and female students showed higher stress score for academic, personal, and surrounding environmental (P < 0.05, respectively) factors than male students. Dietary habit score (P < 0.01) and nutrition knowledge score (P < 0.05) in female students as well as dietary attitude score (P < 0.05) in male students were negatively correlated with life stress score. Dietary habit scores in male and female students were positively correlated with dietary attitude score (P < 0.01, respectively). Need for nutrition education was significantly higher in female students than in male students (P < 0.05). Conclusions: This study provides basic information on dietary habits, dietary attitudes, life stress, and nutrition knowledge according to sex and suggests gender-specific practical nutrition education programs to address undesirable dietary habits and attitudes in students with higher stress levels.

In this paper, a research for the knowledge based configuration design software development of a train vehicle has been presented. Parametric design and knowledge based design concepts have been introduced for rapid design changes and analyses using a commercial CAD software, $CATIA^{/circledR}$ Knowledgeware module. Positions and dimensions of door, small window, large window, and number of seats were used as design parameters. It is crucial for train vehicle design because it enables rapid conceptual design by instant configuration changes. The results of this research can be used as one sub module of the multidisciplinary train vehicle design software and provide a basic data for rolling stock behavior and driver cab ergonomics of a train vehicle.
