This study was performed to investigate the nutrition knowledge, attitudes, and dietary habits of physical education (PE) major and non-majors of male college students. The subjects were 253 students residing in Gyeonggi area. Nutrition knowledge scores of PE major students were lower than that of non-major students. Both PE major and non-major students reported TV, radio, and internet as their primary sources of nutrition information. Overall dietary attitude scores of two groups did not differ significantly, but PE major students showed more positive attitudes than non-major students for 'Enjoy eating foods that are good for health'. PE major students took more number of meals a day and took more irregularly than non-major students. Also they used more nutrient supplements than non-major students. PE major students drank more amounts of alcohol and drank more frequently than non-major students. But the smoking status of the two groups was not significantly different. PE major students scored higher than non-major students in dietary habits on balance of meals in spite of their low nutrition knowledge scores. Therefore, it is suggested that nutritional programs for PE major and non-major college students should be developed. (Korean J Community Nutrition 14(4) : $363{\sim}373$, 2009)

This study examined the effects of a nutrition education program on nutrition-related knowledge, eating habits, and dietary behavior. Subjects were 3rd grade elementary school students in Anyang, Gyeonggi-do. A 5-week nutrition education program was implemented to 28 children and another 26 children were included in the study as a control group. A self-administered questionnaire was used to assess the effects of nutrition education program. Mean nutrition related knowledge score was improved after education (p < 0.001). There was a significant improvement in knowledge of nutrient source (p < 0.05), role of protein (p < 0.05), food tower (p < 0.001), getting information from nutrition labeling (p < 0.05), and proper way of snacking (p < 0.001). Eating habits and self-efficacy also tended to improve by nutrition education, especially eating habit of snack and self-efficacy on balanced diet reached significant improvement (p < 0.05). Food consumption frequency was not changed significantly, only consumption of sea weeds which is considered as a reluctant food among children was increased after education (p < 0.05). In addition, the number of leftover food items and total amount of leftover at school lunch reduced significantly after education when compared with the same 10-day menu prior to education (p < 0.01). This result suggests that unbalanced dietary behavior has been changed with the nutrition education program. In conclusion, the nutrition education program was found to be effective in improving nutrition-related knowledge, eating habits, and dietary behavior.

The purpose of this study is to investigate the relationship between of weight control attempts with concern about weight control. nutrition knowledge, eating behavior and nutrients Intake among high school girls in Seoul, Korea. A self-administered questionnaire was distributed to 355 subjects. The subjects were then divided into two groups, one with experience in attempting to control their weight, and one with no experience in attempting to control their weight. The mean averages of height, weight. obesity index (OI) and BMI of the subjects were 161.1cm, 53.1kg, -5.2% and 20.4, respectively. 49% of the subjects were experienced in attempting weight control. The majority of the group that had experience in weight control expressed dissatisfaction of with their self body image (66.7%), and was concerned about weight control (94.9%). This group also had more abnormal eating habits than the group that had no experience in weight control attempts, such as missing meals, eating irregularly, not eating a variety of foods and snacking. The mean averages of perceived knowledge (PK) and correct knowledge (CK) regarding nutrition on a 30 point scale were 23.6 (78.7% of total score) and 15.8 (52.7%), respectively. There were no significant differences of the PK's and the CK's between the two groups. Nutrients intakes of the two groups were not significantly different and the mean nutrient intakes revealed adequate consumption of energy. protein, Fe, Ca. thiamin. riboflavin, niacin, vitamin A and C. The higher the dissatisfaction of their self body image, PK score. and abnormal eating habits, the higher the level of concerns about of being overweight.

This study was conducted to investigate effects of nutrition education and exercise intervention on health and diet quality of middle-aged women. The subjects were 209 women who wanted to involve in the health promotion program run by Jincheon-Gun Health Center. Nutrition education was given once a week and dance sports were done twice a week for 3 months. Nutrient intakes were assessed by 24-hour recall method and food records. Dietary habits and nutrition knowledge were investigated by self-administered questionnaires before and after the intervention program. Body and blood compositions were measured before and after the program. The nutrient adequacy ratio (NAR) was significantly increased in energy, protein, vitamin A, vitamin B2 and calcium, mean adequacy ration (MAR) was significantly increased (p < 0.05), and also the index of nutritional quality (INQ) was significantly increased in protein (p < 0.01). Percent (%) RIs of protein (p < 0.01) and calcium (p < 0.05) were significantly increased and body weight (p < 0.001), body fat (p < 0.01), soft lean mass (p < 0.01) and BMI (p < 0.001) decreased. Over the 3-month study, there was a significant trend toward higher HDL-C and albumin levels and lower LDL-C level (p < 0.001). The results showed that nutrition education and exercise intervention could improve the body health and the diet quality.

The use of food frequency questionnaire to estimate dietary intake has become widespread in epidemiologic studies. It has been suggested that knowledge about a person's usual serving size of each food, in addition to consumption frequency, will improve the accuracy of this method. This study was performed to investigate the nutritional status and one sowing sizes of commonly consumed dishes in Korean college women. Intakes of dish or food in 156 college women were measured by 7-day weighed food records in May, 1992 and May, 1993. For each dish or food, variance in one serving size was partitioned into within-person(intraindividual) and between-person(interindividual) components. All nutrient intakes except vitamin A and vitamin C were less adequate. The major dish groups which contributed to the most daily nutrient intakes were boiled rice, bread, fruits, dairy product, and biscuit and snack groups. In more than 50% of dishes, the within-person variation was greater than between-person variation. And the variety and amount of food which was used in one dish were too variable to make standard recipe.

Thinness has become a symbol for beauty acceptance and competence for women in our society especially for young college women. Relatively little is known about characteristics of women who are dissatisfied with their shape or weight and who are interested in performing weight control program. Four hundred college women in Seoul and Kyunggi-Do area were surveyed from November to December 1992 to investigate the relationship between the concern about weight control and various aspects of food related behaviors. The purpose of this research was to investigate the relationship between the weight concerns of college women and their aspects of several eating behaviors. Self-developed questionnaire was used after validity test. The results were as follows: 1) The average height weight and BMI value of subjects were 160$\pm$4.5cm 51.02kg and 19.86$\pm$4.5 respectively. 2) The 49% of subjects were highly concerned about weight control(high interest group) and 39% were moderate concerned(moderate interest group). 3) The average BMI and weight change per year were significantly higher in the high interest group than other groups. 4) The score of nutrition knowledge was also higher in the high interest group, 5) There were no significant differences among groups in the meal frequencies. and amount of nutrients intake. 6) The signs of eating trouble were found in subjects 59.0% of subjects felt feareness about weight gain after consumption of large amount of food. 7) The ratio of CPF was 64:14:22 and nutrient adquacy ratio(NAR) of energy was 0.94 NAR of Fe was 0.84 the other NAR of nutrient over 1.0.

The purpose of this study was to compare food habits and nutrient intakes with body mass index of hypertensive patients commuting to a Local Health Center. A total of 85 patients were divided into two groups according to BMI. The non-obese group comprised 43 subjects with BMI below 25㎏/$m^2$ , while the obese group comprised 42 subjects with BMI above 25㎏/$m^2$ . All Subjects were interviewed for general characteristics, food habits, clinical characteristics, effort for health maintenance and the knowledge of hypertension and nutrition. Anthropometric assessments such as weight, height, waist-hip ratio and biochemical measurement of blood urea nitrogen, creatinine, triglyceride, total cholesterol, HDL-cholesterol and fasting blood glucose(FBG) were obtained from subjects. In general characteristics, smoking, drinking, exercise, and hypertension status were not significantly different between the two groups. Food habits and the means of daily energy and nutrients were not significantly different between the two groups. An analysis of the percentage of RDA(Recommended Dietary Allowances of Korea, 2000) consumed by patients showed that but for ascorbic acid and phosphorus, all nutrients were below the RDA. And intakes of vitamin $B_1$(P<0.001), vitamin $B_2$(P<0.01), niacin(P<0.001) of the obese group were significantly lower than that of the non-obese group. Blood urea nitrogen, creatinine, triglyceride, total cholesterol, HDL-cholesterol and fasting blood glucose were in the normal range and there was not a significant difference in the two groups. Therefore, more effective nutrition education programs about exercise, smoking, caloric intake, vitamins and minerals are required for hypertensive patients commuting to Local Health Center.

Various cultural practices have been promoted as management options for enhancing soil quality and health. The use of soil management methods can cause changes in fertility by affecting soil chemical properties. This study aimed to evaluate interactions between soil chemical properties and soil management methods in protected cultivation, and to classify soil management methods that similarly affect soil chemical properties. Water-logging and irrigation reduced soil pH and available $P_2O_5$ content. Application of animal manures has a positive effect on levels of organic matter, Av.$P_2O_5$, K, Zn, and Cu. The electrical conductivites tened to be low in the application of organic amendments, including rice and wood residues. Deeper plowing caused a reduction in Ca content. Practicing soil nutrient-considering fertilization and fertigation did not exert an influence on nutrient element contents. In a cluster analysis of the soil management methods according to major nutrients, low similarities were found with deeper plowing and crop rotation with rice in comparison with other practices. In a cluster analysis by minor nutrient characteristics, crop rotation and application of animal manures and rice residues were linked at a high Ward's distance, while other practices were found to be relatively low distinct. Each soil management method has a similar or different effect on soil chemical properties. These results suggest the necessity of establishing limits and standards according to the effects of soil management methods on soil chemical properties for economic soil practices.

For the purpose of developing 'Web-Based Nutritional Education Program', this study analyzed nutritional problems of junior/senior high school students and set appropriate instructional goals for nutritional education program. Survey questionnaires were distributed from October 21,2002 to October 26, 2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9％ of the total questionnaires distributed. According to the survey results, three student groups (male and female students at junior high schools and female students at senior high schools) had lower than an ideal body weight. In case of their Basal Metabolic Indices (BMI), the female students and junior high school students showed a tendency to be underweight, while the other three student groups were within the normal range. The result of the survey showed that all four groups of students showed a deficiency in nutrient intake of calories, calcium and thiamin when compared with Korean RDA. Particularly, in the case of the female students at senior high schools, the deficiency of iron intake was a problem. The survey about food attitudes and food habits of the students showed that the senior high school students had more problems when compared with their junior high school counterparts (p < .001). Therefore, the instructional goals of nutritional education program were set as follows: 1) To improve the level of understanding and the perception of junior and senior high school students about the importance of a dietary lifestyle. 2) To change food attitudes and nutritional knowledge related to individual dietary 1ifestyle, so as to maintain good health through the enhancement of the students' physical activities. We found out that it is critically important to factor in the existing problems of food attitudes and food habits, as well as nutrient intake among junior and senor high school students when setting objectives for nutritional education programs.
