The purpose of the study was to develop a nutritional counseling program using expert system to assist obese people to lose weight through behavior modification in the internet. The counseling internet program for weight loss was developed by the accumulation of knowledge for dealing with eating habits and exercising behaviors into expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. KEA was built based on the theory of Multiple Classification Ripple Down Rules. To accumulate knowledge into KEA, survey was performed in 150 obese people, the dietitian reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaires were the same as those of the internet consulting program, and they included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. KEA was used for nutritional counseling of obese people after KEA had enough knowledge for weight loss based on behavior modification by the dietitian. To accumulate knowledge to KEA, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors for losing weight. When clients answered survey questionnaires in a counseling internet program, KEA gave the recommendation how to eat, to exercise and the deal with stress in a real time for each case. If KEA did not have enough knowledge for a specific case, the conclusion window wrote no conclusion and the dietitian needed to add conclusions for the case. The conclusions for the new case added to the KEA knowledge base. In conclusions, a counseling internet program for weight reduction can be used for give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.

The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.

This study was designed to investigate the impact of a 12-week nutrition education program on 32 male industrial workers (average age: $44.5{\pm}3.8$ yrs, work duration period: $20.1{\pm}5.6$ yrs) diagnosed as having dyslipidemia in a medical checkup at their workplace. This program was implemented with a conceptual framework on strengthening self-efficacy for the improvement of the health conditions of the workers. Most of all, the study exhibited benefits in the industrial workers by ameliorating the risk factors associated with dyslipidemia via changes in dietary behaviors, nutritional knowledge, and attitudes, as well as anthropometric and biochemical parameters. After the nutrition education, overall lifestyle, including the ratios of smoking (P<0.05) and drinking (P<0.01), significantly improved. Exactly 65.6% of the subjects reported that their dietary habits changed. Body weight, BMI, percentage of body fat, and waist circumference all significantly decreased (P<0.001). The systolic (P<0.01) as well as diastolic blood pressures (P<0.001) decreased. Moreover, the degree of increase in serum HDL-cholesterol was appreciable (P<0.001), and the atherogenic index also decreased (P<0.01). Further, risk factors related to metabolic syndrome in subjects significantly decreased (P<0.001). The average scores for nutrition knowledge increased from 9.3 to 17.7 points (P<0.001). All of the participants agreed on the need for a nutrition education program at their workplace.

This study was conducted to investigate the effects of a weight control programs on BMI, nutrition knowledge, physical fitness and stress level of adult obese women. The subjects of this study were 36 adult obese women aged 30-65 years whose BMI were above $23\;kg/m^2$. The weight control program for obese women included nutritional education, exercise and cognitive behavioral therapy for 12 weeks. The BMI of the subjects was significantly decreased (p < 0.001) from $27.1\;kg/m^2$ to $26.4\;kg/m^2$ after the 12 weeks of the weight control program. In addition, the weight of body fat was significantly decreased (p < 0.001) and % body fat was significantly decreased (p < 0.05) from 35.4% to 34.9% after completion of the weight control program. In addition, nutritional knowledge (p < 0.001) and eating behavior scores (p < 0.01) were significantly increased. However, the food intake scores were not changed after the program. Stress levels of the adult obese women were significantly decreased (p < 0.001) from 85.63 to 66.88 and also obesity stress levels were significantly decreased (p < 0.01) after the weight control program. In the physical fitness levels of the subjects, muscle endurance (p < 0.05) and ability of balance (p < 0.01) were significantly improved after completion of the weight control program. There were positive significant correlations between general stress and obesity stress level (p < 0.05), and negative correlations between stress level and food intake score (p < 0.05). These results showed that the weight control program for adult obese women may be effectively used to improve weight reduction, physical fitness and stress levels.

This stusy was designed to develop nutrition education program for the primary school children served by the national school lunch program and to evaluate ist educational effects. Subjects consisted of 61 elementary school children(30 in the control group and 31 in the treatment group) in the 5th grade. Only the treatment group participated in a twelve-week nutrition education program. To evaluate the effects of the nutrition education program, the control and treatment groups were given a pretest and posttest for nutrition knowledge, food attitude, food habits, food preference and plate wastes before and after nutrition education. The results obtained are summerized as follows ; the nutrition knowledge test score (30.4) of the treatment group was significantly higher than that (17.4) of the control group after nutrition education . However, there was no significant difference between the two groups in food attitude test scores after nutrition education. We also did not find any difference induced by nutrition education or the food preferences of the treatment group. After nutrition education , the amount of plate waste of some menus were significantly decreased in the treatment group, but the amount of plate waste of the control group was not significantly changed. However, there was no significant difference in the post test scores above food habits between two groups. It was concluded that a twelve-week nutrition education program can improve nutrition knowledge and decrease plate waste but is not enough to change food attitude , food preference and food habits. It can besard that the two components of foodservice are nutritional foodservice and nutrition education. Foodservice management alone without nutrition education is hardly enough to improve the nutritional status of school children. The result of this study indicate that applying the nutrition education program to elementary school children who are served by the national lunch program can maximize the effects of the national school lunch program.
