This study examined health foods intakes and related variables among the middle aged(150 men and 159 women) in the Jeonbuk region. Health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured health food supplements(MHFS). The number of people taking health foods were higher for those in their 50's than in their 40's. The consumption rate of TF in men was the highest among health foods, this result had significance. The reasons for taking health foods were recovery from fatigue, supplement of nutrients and making smooth body activity in general, but TF was used to increase of vigor. The consumption rate of health foods was a little different according to social-economic factors, namely, the consumption rate of CM was higher in people in rural than urban areas, those who graduated from middle school than university, blue color & self-employed as opposed to housewives and service workers, low level income than high level income, and Buddhism and no religion than Christian. The consumption rate had a correlation with the habits of smoking, alcohol drinking and exercise ; namely, the consumption rate of CM was higher than VMS and MHFS on smokers and alcohol drinkers. The more the frequency of exercise, the higher the consumption rate of TF, but the duration of the exercise was not correlated. This study suggests that middle aged people need nutritional education for the right recognition and selection of health foods and to consider the nature of each type of health foods.

With recent increases in demand for women's social participation, children have tended to favor western-style foods and dislike vegetables (Veg.). The objective of this study was to evaluate dietary behavior and Veg. intake in 612 elementary school children (339 boys; 273 girls) in Gyeonggi-do. 66.5% of the subjects reported that they liked Veg. The most frequent reason given for this preference in Veg. liking group was that vegetables were 'delicious' (35.6%), followed by 'nutritious' and 'frequent intake'. The most frequent reason given for disliking Veg. in the Veg. disliking group was that vegetables are 'not delicious' (94.6%). Approximately half of the subjects had correct knowledge about vegetables. The total score of general nutrition knowledge was 7.7 points (a perfect score is 10 points) and the majority of students generally had good dietary behaviors. The Veg. liking group scored higher on knowledge about Veg., general nutritional knowledge, dietary behavior, and Veg. preference than did the members of the Veg. disliking group (p<0.001). The 'active' group had the highest score for dietary behavior (p<0.001), and the scores for dietary behavior and Veg. preference increased with increasing self-rated health status (p<0.001). The score of normal BMI group for nutritional knowledge about Veg. was higher than that of the underweight group (p<0.05). The higher self-rated academic score group showed higher on knowledge about Veg., general nutrition knowledge, dietary behavior (p<0.001) and Veg. preference (p<0.05). Dietary behavior and preference of Veg. were positively correlated with nutritional knowledge. To improve health by increasing Veg. intake, education about the nutritional importance of Veg. should be needed, and continuous nutritional education is recommended to foster good food habits and Veg. preferences in children.

This study was carried out to analyze the effects of dietary and life-style factors on the prevalence of depression in Korea. Epidemiologic data from a nation-wide sample of 2,000 adults who were selected with the stratified random sampling method in Korea were interviewed by trained interviewers. Data were presented on the CES-D, a 20-items self-report depression symptom scale developed by the Center for Epidemiologic Studies in U.S.A. The prevalence of depression among all the respondents was 13.5%, with 13.1% in urban samples and 15.5% in rural samples. The prevalence was higher in females(15.3%) than in males(11.7%). There were highly marked differences in the prevalence of depression by sex(p<0.05), age(p<0.0001), education(p<0.001) and income(p<0.01). Respondents of 60 years and over group, the less educated group(below elementary school graduated), and the less income group(less than 400,000 won/month) reported the highest rate of depression. However subjects' occupation and residence had little relation with the prevalence of depression. Drinking and smoking habit appeared to be highly associated with depression in females(p<0.0001) but not in males. The prevalence of depression and eating behavior were highly related(p<0.005). Male respondents below 20 years, 20-29, and 60 years and over depressed group reported significantly lower energy and protein intakes compared to that of the normal group. However, in the female respondents 20-29 years and 60 years and over depressed groups showed the significantly lower energy and protein intakes compared to those of the normal groups(p<0.05), it can be concluded that the various ecological factors such as epidemiological, dietary, and health factors may affect the prevalence of depression among Korean.

The purpose of this study was to examine the long term effects of breast feeding on growth, bone development and nutrient intakes in preschool children. Subjects were 62 preschool children. Anthropometric characteristics and bone mineral density of carpus were measured using DEXA. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the boys was 62.4 months and that of the girls was 62.1 months. Average birth height and weight of the subjects was 50.9 cm and 3.4 kg for boys and 50.3 cm and 3.3 kg for girls, respectively. The average height, weight, $\%$ body fat, and obesity index were 111.7 cm, 19.6 kg, $15.0\%$, $-2.1\%$ in boys and 109.4 em, 18.7 kg, $17.5\%$, $0.2\%$ in girls, respectively. Forty children were fed colostrum, 21 were fed breast milk, 29 were fed formula, and 12 were fed mixed milk. There was no significant difference in growth status between children who were fed colostrum and those who were not. Children who had mixed feedings were significantly taller than those who did not (p <0.001), and children who had colostrum had significantly higher bone mineral density than those who did not ($0.25 \pm 0.04 g/ cm^2$ vs. $0.23 \pm 0.04 g/cm^2$, p < 0.05). However, the different feeding methods did not show any difference in bone mineral density. Except vitamin $B_6$, folic acid and vitamin E, vitamin, mineral and calorie intakes did not meet the Korean RDAs. Calcium intake was especially lower than recommendations by as much as $62\%$ and $70\%$ in boys and girls, respectively. There was no significant difference in nutrient intakes between children who had colostrum and those who did not. However, children who were formula consumed significantly more animal fat than those who did not (p < 0.05). Neonatal feeding and breast or formula feeding seems to associate with height, bone mineral density and animal fat intakes in preschool children, based on the results of this study. A longitudinal study is needed to clarify this relationship.

동치미를 동결하면 미생물의 사멸, 및 성장과 효소의 작용이 정지되어 더 이상 발효가 진행되지 않아 산패 및 조직의 연화를 방지할 수 있으므로 동결 저장은 동치미의 효과적인 저장 방법이다. 그러나 일반적인 동결 방법과 해동 방법으로는 동결 및 해동 공정시 품질의 변화가 발생하는 문제점이 있기 때문에 액체질소를 이용한 급속 동결 및 915MHz microwave을 이용한 급속 해동 공정을 실시하였다. 동치미를 제조한 후 발효 적숙기인 pH 3.8에서 동결하였는데 동치미 무와 액을 함께 동결할 경우 동치미 무의 hardness가 크게 감소하기 때문에 무와 액을 각각 분리하여 동결시켰다. 동치미 무의 size는 $2{\times}2{\times}6cm$이 품질의 변화를 최소화할 수 있는 크기이었고, 동치미 액은 $5{\times}5{\times}10cm$로 설정하였다. 동치미 무의 경우 액체질소로 동결하고 915 MHz microwave로 해동하였을 때 조직의 hardness에 기여하는 pectinesterase activity가 가장 높았고, 조직의 연화에 작용하는 polygalacturonase activity가 가장 낮아서 hardness가 가장 좋았으며 색도의 변화도 가장 적었다. 동치미 액의 경우 $-70^{\circ}C$에서 동결하고 915 MHz microwave로 해동하였을 때 pH와 산도의 변화가 적었으며 미생물이 가장 많이 사멸되었다. 따라서 급속 동결 및 급속 해동을 이용한 저장방법은 동치미의 장기 저장 시 효과적인 방법으로 판단되었다.

Iron deficiency and anemia are severe nutrition problems in most of Korea. Iron intake, especially iron with better bioavailability is insufficient over a total age group. Recent changes in diet and life style of Koreans have been repeatedly suggested problems caused by excess nutrient intake rather than under intake. Despite the changes in diet patterns, iron deficient anemia is still prevalent in many parts of Korea. Eight hundred and fifty subjects (323 male and 527 female subjects) in Asan were recruited from farming, factory and urban area. Each subject was interviewed to assess nutrients intakes according to a 24hr-recall method. Twelve hour fasting blood samples were collected to vacutainer with EDTA for hemoglobin (Hb) and separate the tubes for serum iron (SI) and total iron binding capacity (TIBC). The mean serum iron value of female subjects in the factory area was significantly higher (p < 0.05) than that of the female subjects in the urban area although subjects in urban area showed significantly higher the dietary iron intake for both the men and woman (p < 0.05). Dietary iron intake for the younger women was lowest in the farming area and those in the urban area showed the highest dietary iron intake (p < 0.05). When the dietary iron intake was compared by different the age groups, dietary iron intake of the older women from animal sources was less than that of younger women in the urban area (p < 0.05). Dietary iron intake of Asan residents was not sufficient regardless of age, sex and regions and intake of heme iron was especially lower than nonheme iron. (J Community Nutrition 5(1) : 37∼43, 2003)

As many people are westernizing their life style and food consumption habits, a number of patients who have malignant tumors which grow very rapidly and hazardously destroy the human body are increasing. Ultrasonic hyperthermia is not only one of the tumor treatment methods which employs the non-radioactive ultrasonic waves to increase the temperature at the tumor region up to $40\sim45^{\circ}C$ to destroy and suppress tumor cells but also has been proved by many studies. Due to the rapid development of High Intensity Focused Ultrasound(HIFU), the ultrasound hyperthemia extensively boosts its applications in clinical field. For those reasons, Computed simulation factor should be needed before inspection to patients. To prove efficiency of ultrasonic hyperthermia, precise acoustic field measurement considering tissue characteristics and a heating experiment with tissue mimicking material phantom were conducted for effectiveness of simulation program. Finally, in this study, the computer simulation program verified the anticipated temperature effects induced by ultrasound hyperthermia. In the near future, it is hoped that this simulation program could be utilized to improve the efficiency of ultrasound hyperthermia.
