Objectives : This study tries to find the educational basis based on the radiation safety knowledge, attitudes and behaviors to check the level of radiation safety behavior in domestic students who study dental hygiene. Methods : The students of 3rd and 4th grades in 83 universities which have registered on the Korean University Education Council were involved, and they were given a questionnaire for this study. The questionnaire was provided via visit with 20 copies to each university (total 1660 copies), mail by post and e-mail. Among them, we analyzed only 723 copies that we can trust. The data were analyzed with frequency, percentage, mean, standard deviation and Pearson's correlation using the SPSS/WIN 15.0. Results : As a result, there are correlations in the students' knowledge, attitudes and behaviors regarding the radiation safety management. It means that the education which can improve the knowledge and attitudes should be applied to increase the action level of the radiation safety. In addition, the physical environment is the most closely correlated with the individual behavior, so it will be limited to improve the behavioral levels of the radiation safety if the physical environment is not prepared. Therefore, the physical environment should be supported to enhance the level of the radiation safety activity, and to increase the individual attitude level of radiation safety. Conclusions : The knowledge level of the radiation safety management is relatively lower than the attitudes level, and the behavior level is the lowest. Therefore, the education policy of the safety behavior must be enhanced. For domestic students, the educational intervention is necessary to improve their behavioral level of radiation safety management because they will be able to reduce the amount of radiation exposure of their patients in dental care after getting a job.

This study was carried out to investigate perception about body image, dietary attitude, nutrient intake and dietary self-efficacy of high school students in Pusan. A questionaire survey was distributed among 491 high school students. The survey was conducted from April 8 to April 22 in 2002. The results are summarized as follows. Forty percents of the underweight group, 53.9% of the normal weight group, 61.8% of the overweight group and 48.2% of obesity group have correct perception about their body image. Most of the students were concerned with their body image and weight control. Obesity of parents was significantly correlated with obesity of the subjects (p<0.01). The higher obesity rate, the lower dietary self-efficacy. The higher dietary self-efficacy, the higher dietary attitude. There was a significant positive correlation between the education level of their parents and dietary attitude of the subjects (p<0.01) and a significant negative correlation between obesity rate of their mothers and dietary attitude of the subjects (p<0.01). Dietary attitude scores showed no significant difference among the groups. Intakes of most nutrients, except protein, niacin and vitamin C, were lower than those of the recommended dietary allowances for Koreans. Therefore, proper nutrition education is required to improve their nutritional status and dietary self-efficacy.

The adolescent period, during which physical, spiritual, and physiological growth and development occurs, is important for the development of healthy dietary habits. Particularly, eating a regular breakfast improves eating habits and school life in adolescents but few studies have investigated the effects of eating breakfast on these outcomes. Therefore, this research was performed to investigate the effects of eating a regular breakfast provided by the 'Breakfast Club Program' on eating behaviors and school life. A total of 315 high school students were recruited for the program from 10 high schools in nine districts among 25 districts in Seoul during August to December of 2013. The average age was $17.8{\pm}0.8$ years and 38.1% of students were females. Based on 315 subjects, 38.3%, 35.7%, and 17.1% increased their intakes of breakfast (P=0.001), fruit (P=0.033), and milk (P<0.001) up to 5~7 times per week, respectively. The intake frequency of fruit (P<0.001) and eating breakfast (P<0.001) increased noticeably after program participation. Based on 64 students performing dietary record, intakes of cereals (P<0.001), mushrooms (P=0.027), and fruits (P=0.002) increased while intakes of eggs (P=0.001) and fat and oils (P=0.019) decreased after the program. Consumption of energy (P=0.004), plant protein (P=0.012), carbohydrates (P<0.001), dietary fiber (P=0.026), iron from plant sources (P=0.009), potassium (P=0.043), zinc (P=0.013), vitamin $B_1$ (P=0.043), and vitamin C (P<0.001) increased whereas intake of cholesterol (P=0.002) decreased. Regarding school life, the score for 'comfortable and cheerful starting of a day' (P=0.001) and 'healthy starting of a day' (P<0.001) increased significantly. This study indicates that a regular 'Breakfast Club Program' may establish healthy eating habits and school life in teenagers.

The purpose of this study was to investigate foodservice satisfaction in high school boarding students in Busan. To achieve the research objectives, a questionnaire was distributed to 357 students at four high schools in Busan. From the results, 83.8% of students ate breakfast every day, and more female students ate breakfast daily compared to male students (P<0.05). However, 53.2% of students ate 'almost-all' amounts of breakfast compared to lunch (86.6%) and dinner (87.5%). The average students' foodservice satisfaction score was 4.04/5.00. The highest satisfaction category was sanitation, followed by the service and food categories. Freshmen showed significantly higher foodservice satisfaction than junior students in terms of service (P<0.05), sanitation (P<0.05), and food categories (P<0.01). As for satisfaction of each meal, breakfast scored 3.15, lunch scored 4.04 and dinner scored 4.12, whereas male students showed significantly higher satisfaction than female students in breakfast (P<0.05) and dinner (P<0.05). Freshmen showed significantly higher satisfaction than juniors in breakfast (P<0.001), lunch (P<0.001), and dinner (P<0.001). As for meal type preference of each meal, female students strongly preferred Korean food for breakfast (P<0.01). This research suggests that it is necessary to improve breakfast satisfaction by developing a variety of menu items.

The aim of this study was to examine and compare the eating habits, dietary intake patterns and nutrient intake status of children with and without atopic dermatitis by questionnaire during July, 2008. A total 388 subjects of 5th and 6th grade elementary school children (AG: atopic group, n=65, NG: non-atopic group, n=323) in Seoul and Ulsan areas participated in this study. The questionnaire included general characteristics, dietary habits, and atopy-related food frequency. One-day 24 hour recall was collected to estimate nutrient intakes of the subjects. The data were analyzed by Chi-square test for food frequency analysis and by t-test for nutrient intakes. Atopy-related foods included milk, buckwheat, beef, pork, chicken, crab, egg, mackerel, peach, and tomato. From the findings, AG had a more irregular eating habit than NG (p<0.05). In case of food frequency, AG tended to consume more atopy-related foods than NG (p>0.05). The nutrient intakes of AG were significantly lower than those of NG (p<0.05), but only intake of animal iron in AG was higher than NG (p<0.05). NG consumed more protein than AG (p<0.05). Although milk was a noted hypersensitive allergic food, frequency and the amount of milk intake were not significantly different between two groups. In conclusion, atopic children had eaten more atopy-related foods and less nutrient intakes. Therefore, it is necessary to educate on good nutrition and guide atopic children and their parents.

The purpose of this study was to evaluate the importance and performance of middle school foodservice hygiene in Busan. In this study, questionnaires were administered to 1,000 students consisting of 100 students in 10 middle schools in Busan in December, 2013. The students assessed importance and performance of personal hygiene as 3.81 and 3.60 on a scale of 5.00, respectively. Males gave higher scores to importance and performance of personal hygienic than females. First grade students gave significantly higher scores than 2nd and 3rd grade students to importance and performance of personal hygienic. The mean scores of importance of foodservice hygiene were 4.47 for food hygiene, 4.25 for equipment hygiene, 4.23 for employee hygiene, and 4.19 for environment hygiene. For importance of foodservice hygiene, females gave significantly (P<0.001) higher scores than males. However, male gave significantly higher scores than females for performance of foodservice hygiene. The importance and performance grid showed important factors for personal and foodservice hygiene. 'Hand washing before eating the meal' for personal hygiene and 'cleanliness of tray' for foodservice hygiene showed the highest importance and lowest performance scores. Foodservice hygiene can be improved through customized education of students regarding meal service and food hygiene, equipment hygiene, and environment hygiene.

The purpose of this research was to evaluate concretely how the 7th Technology Home Economics(HE) curriculum was operated In school fields by using context evaluation, input evaluation using the CIPP model focusing HE. In this research. a questionnaire survey was done targeting HE teachers in charge of technology and home economics subject for the 7th curriculum implementation at 250 randomly selected middle schools in Gpoungsangnamdo, and 109 returned questionnaire papers were used for the final analysis. The frequency, percent, mean and standard deviation of these data were obtained by using the SPSS 10.0 for Windows Program. The results of this research were outlined below: First, with a regard to the context evaluation (evaluating educational contexts), the requirement degree of seeking for career appeared to be the highest at the requirement survey of the education goal and character of HE area, and the requirement degree of elevating understanding home living' were very low. Interest and concern of students towards these subject as well as the self-confidence of HE teachers in charge were low. Second, as for the input evaluation (evaluating education plans), time allocation, content level, and content amount were not regarded to be not proper, and the composition of HE educational curriculums and the class guideline of teachers also were not so faithful from the aspect of school level. Among surveyed items, establishing plans in school level towards evaluation was relatively sincere, but discussions about curriculums were not so faithful, suggesting various kinds of content are not fully discussed. As shown by the results above, it is difficult to say that the operation of the 7th HE educational curriculums has secured its position perfectly. It is necessary to examine systematically the educational goals. character of the 7th HE educational curriculum and the appropriateness of curriculum content, and to seek various methods to elevate the self confidence of teachers and the interests of students. Because how to operate national level educational curriculums in school levels with self-regulation and elasticity will be an important variable in realizing educational goals, teachers, the main body of educational curriculums and direct performers, should establish and perform educational plans in school levels to elevated the satisfaction of teachers and educational effects for normally operating educational curriculums. In addition, educational curriculums should be operated and evaluated mainly by teachers at school fields to make it possible to confirm and check the achievement of the goals of educational curriculums qualitatively.

In this study, we look at the effect that the achievement goal of specialized high school students has on academic self-efficacy and the difference in academic self-efficacy depending on achievement goal orientation. The purpose of this research is to help students to efficiently increase their academic self-efficacy, develop research and study life guidance measures to improve negative factors, and select professors and learning methods. To achieve the purpose, survey was conducted with achievement goal orientation measurement tools(26 questions) and academic self-efficacy measurement tools(28 questions) for 745 students of 18 specialized technical high school students in 5 districts. The results of this study are as follows. First, preference to task difficulty and self-controlling efficacy have highly positive correlations with mastery goal orientation and confidence and mastery avoidance goal orientation have highly negative correlations each other. Second, achievement goal orientation form of specialized high school students were divided into 5 forms; 'execution avoidance(34.8%)', 'mastery orientation(20.8%)', 'approach(17%)', 'avoidance competition(14.9%)', and'mastery avoidance(12.5%)'. In preference to task difficulty, 'approach'group showed the highest average point and 'mastery avoidance'showed the lowest average point. The average point of 'approach' group was higher than other groups in confidence, but 'mastery orientation' group showed the highest average point. Through the results of this study, academic self-efficacy makes an effect by a certain direction in accordance with achievement goal orientation and it's necessary to access academic problems differently according to student's goal directivity. Therefore, it's necessary to provide educational method by student type based on explanation about academic self-efficacy of achievement goal orientation of specialized high school students and analysis on achievement goal orientation form.

This study was conducted to assess the microbiological quality of raw and cooked foods served in the elementary school food service. Raw and cooked food samples were collected from 11 selected elementary schools in both June to July and September to October of 2005. Petrifilm plates were used to determine (in duplicate) total aerobic colony counts (PAC), Enterobacteriaceae (PE), coliform counts (PCC), and E. coli counts (PEC). Heavy contamination of Enterobacteriaceae (from 0.08 to 7.40 log CFU/g) and total coliform (0.50 to 6.52 log CFU/g) were observed in raw materials and cooked foods. Escherichia coli (E. coli) were detected in the sample of currant tomato (3.70 log CFU/g), sesame leaf (3.59 log CFU/g), dropwort (0.20 log CFU/g), crown daisy (3.15 log CFU/g), parsley (3.00 log CFU/g), peeled green onion (1.74 log CFU/g), frozen pork (0.65 log CFU/g), frozen beef (0.20 or 1.50 log CFU/g), chicken (1.78 log CFU/g), and young radish leaf seasoned with soybean paste (1.24 log CFU/g). Multiplex PCR system was used to determine the food-borne pathogens: Salmonella spp., Bacillus cereus (B. cereus), E. coli O157:H7, Staphylococcus aureus, Listeria monocytogenes (L. monocytogenes), Vibrio parahaemolyticus, Campylobacter jejuni (C. jejuni), Shigella spp., B. cereus was detected in 19 samples of raw materials and 8 samples of cooked foods. With regard to quantitative analysis, B. cereus counts exceeded 5.46, 3.48 and 1.79 log CFU/g in sesame leaf, peeled green onion and seasoned mungbean jelly, respectively. E. coli O157:H7 was detected on 2 samples of frozen beefs, and its biochemical characteristics of one beef sample was confirmed with API 20E kit (93.7%). L. monocytogenes was detected in fried rice paper dumpling, but the presumptive colonies were not detected onto the conventional plate. C. jejuni was detected in peeled & washed onion.
