This study was conducted to investigate the nutritional status and factors related to dislike of vegetables in the students who avoid eating vegetables in elementary school. The subjects were classified into VDG (vegetable dislike group, 75 children) and control group (69 children) by amount of vegetable left in school feeding. The survey included the items of demographic characteristics, dietary behaviors, nutrition knowledge, food preference, reason for dislike of vegetables and nutrient intake of the subjects. Dietary behavior and nutrition knowledge scores of control group were higher than those of VDG. The average score of food preference was 4.9 and 4.7 in control and VDG groups respectively. The preference score of root vegetables was the lowest in subjects. In the view of nutrient intake, the calorie intake of control group was higher than that of VDG. Protein intake of control and VDG was enough as compared with their RDA. Except vitamin E, most nutrient intake of control group was higher than that of VDG. VDG consumed lower calorie, vitamin A, vitamin $B_2$, vitamin C, Ca, P, Fe and Zn than control group. The scores of the dietary behavior and nutrition knowledge in the subjects were positively related to the status of some vitamins and minerals intake. These results show that the scores of nutrition knowledge and dietary behavior of VDG were lower than those of control, causing low intake of vitamins and minerals such as vitamin A, Ca and Fe.

Purpose: The purpose of this study was to evaluate the effects of safe handling education of antineoplastic drug on knowledge and performance of clinical nurses. Methods: This was a nonequivalent control-group pretest-posttest study. A total of 49 nurses (25 for the experimental group and 24 for the control group) who dealt with antineoplastic drug within the previous 1 week participated in the study. The guidelines for safe handling of antineoplastic drugs and antineoplastic drugs side effects were provided to the experimental groups whereas only antineoplastic drugs side effects was given to the control groups. Knowledge and performance in reference to antineoplastic drug handling were measured before and 8-week after interventions. Results: The knowledge scores between the pretest and posttest were not statistically significant in both groups. However, the performance scores in the experimental group was significantly higher than that of the control group. Conclusion: The given education of safe handling of antineoplastic drugs had an effect on improving clinical nurses' performance. Thus this education could be routinely administered in practice for those who deal with antineoplastic drugs in their everyday practice.

Purpose: This study was designed to explore the effects of providing individualized education for hemodialysis patients on their knowledge of hemodialysis, compliance of patient role behavior, and physiologic parameters. Method: A quasi experimental design with a non-equivalent control group and a non-synchronized design was used. The experiment was conducted with a total of 40 hemodialysis patients (20 in the experimental group and 20 in the control group) at the artificial kidney center, C University Hospital. The experimental group was provided with individualized education, 30 minutes per session, three times per week, for two weeks. Results: The experimental group had significantly higher knowledge of hemodialysis than the control group after the education. The compliance of patient role behavior was more enhanced in the experimental group than the control group. The experimental group showed significantly higher values of blood urea nitrogen, but not the values of blood creatinine, albumin, kalium, and phosphorus. Conclusion: The individualized education was found to be an effective intervention for improving patients' knowledge of hemodialysis and compliance of patient role behavior.

Purpose: This study was done to determine the effect of CPR training for lay trainees on their knowledge and attitudes. Method: This was a nonequivalent control group nonsynchronized design. The participants were 60 lay trainees who were conveniently assigned to an experimental or control group. The data were collected from July 1 to September 8, 2004 and analyzed using $x^2$-test, t-test and ANCOVA. Results: The 1st hypothesis, 'Posttest CPR knowledge scores for the experimental group will be higher than scores for the control group' was supported (F=59.44, p=0.001). The 2nd hypothesis, "Posttest CPR attitude scores for the experimental group will be higher than scores for the control group" was supported (F=29.94, p=0.001). Conclusion: This CPR training was effective in increasing the levels of knowledge and attitude for the lay CPR trainees.

Purpose: The purpose of this study was to examine the effects of an education program for AIDS prevention on knowledge about AIDS and attitudes towards AIDS/people with AIDS among male-high school students. Methods: A research design used in this study was a randomized and non-synchronized control group pre-and-post test. The participants were 560 male students from five high schools in Seoul and Gyeonggi province. In each school two classes were randomly assigned to each the experimental or control group. The contents of the education program for AIDS prevention consisted of six parts with a total of 50 minutes. The data were analyzed using t-test and chi-square test with SPSS WIN program version 13.0. Results: There were significant differences in knowledge and attitudes between experimental and control groups. The experimental group showed higher scores in knowledge and more positive attitudes than the control group. Conclusion: The education program was effective in increasing positive attitudes towards AIDS/people with AIDS among male high school students. Further application of the program with female students is needed before the results of the study can be generalized.

This study was conducted with a non-equivalent control group experimental design to investigate the effects of a video-based infection control program through the application of the social cognitive theory on caregivers. Forty-six caregivers were recruited, with 23 pairs being randomly assigned to the control and experimental groups each. While the experimental group took part in the video-based education, the control group was involved in typical lectures. For two weeks, both groups were educated on the principles of infection control, medical and external handwashing, standard precautions, and quarantine. Their knowledge, performance, and self-efficacy were evaluated before and after the program. There was a significant increase in knowledge (p<.001 and p=.005) and infection control performance (p<.001) in the experimental and control groups. Similarly, self-efficacy, self-regulatory efficacy, task-difficulty preference and confidence significantly increased in the experimental group (p<.001). In the control group, only task-difficulty preference significantly increased (p=.005). Consequently, the online video-based infection control education program applying the social cognitive theory proved effective in improving the caregivers' knowledge and performance in infection control, and their self-efficacy. We suggest the use of this program in effective infection control education for caregivers in the future.

The purpose of this study was to investigate weight control attempts and related factors among 209 middle school female students in Daejeon. Variables examined were body satisfaction, beliefs regarding weight control, body image, nutrition knowledge, nutritional attitudes, dietary behavior and dietary intake. A cross-sectional survey was employed, and data was analyzed using t-test and chi-square teat (at $\alpha$=0.05). The average height, weight, and body fat (%) of subjects were 160.2cm, 52.4kg, and 25.9%, respectively. Those who attempted weight control were 61.7% of the samples, suggesting that weight control was quite popular among adolescents. Students in the weight control attempt group were more satisfied with their body size (p<0.001), and showed more distorted body image than those in the no weight control attempt group (p<0.001). Most of beliefs regarding weight control were also different in the two groups. The attempt group believed more strongly in the advantages of weight control, and believed less strongly in the harmful effects or difficulties associated with weight control. Although there were no differences in nutrition knowledge in the two groups, nutritional attitudes were slightly more favorable in the attempt group (p<0.01). In contrast, eating behaviors, such as those related to caloric intake (p<0.001), body image (p<0.001), and specific situations (p<0.01) were more desirable in the no-attempt group than in the attempt group. In addition, dietary intake of the attempt group was less adequate than that of the no-attempt group for nutrients such as iron (p<0.01), vitamin A, thiamin, riboflavin, and vitamin C(p<0.05). This study suggests that adolescents who attempt control weight have a more distorted body image and inadequate diet and showed more undesirable eating behaviors. Students should be taught and practice desirable methods of weight control. Educational programs should also include strategies for changing beliefs regarding weight control, as well as modifying diets and eating behaviors.

Objective of the research is to put the vast and complex fault tracking knowledge of human experts in semiconductor production line into the knowledge base of computer system. We mined the fault tracking knowledge of domain experts(engineers of production line) for the construction of knowledge base of the expert system. Object oriented fact models which increase the extensibility and reusability have been built. The rules are designed to perform the fault diagnosis of the items in production device. We have exploited the evidence accumulation method to assign check priority in rules. The major contribution is in the overall design and implementation of the nile base and related facts of the expert system in object oriented paradigm for the application of the system in fault diagnosis in semiconductor production line.
