The purposes of this study were to explore consumer preference for the types of nutrition label of cereal products and to identify some influencing factors on purchase intention and choice probability of nutrition-labeled products. First, most of the respondents preferred the nutrition fact panel with traffic light-GDA(TL-GDA), while the nutrition fact panel only type and the nutrition fact panel with front-of-package(FOP) type were preferred by few respondents. However, consumers evaluated higher for TL-GDA type and FOP symbol type, while the nutrition fact panel only type was evaluated much lower. Second, consumer preference for label types was partially related with 'eating breakfast' and consumer evaluations of the types of labels for the nutrition fact panel only and the nutrition fact panel with FOP were found to be significantly different by gender. Lastly, both purchase intention and choice probability for nutrition-labeled products were found to be significantly influenced by information search and product attitude. In addition, choice probability was found to be significantly influenced by individual characteristics such as gender and grade. It is necessary to find the relationship between nutrition labels and consumer response as this can help consumers make a better choice of food as well as providing some useful information on consumers to the related parties such as companies and consumer organizations.

Reducing women's bone mineral density (BMD) has close relationship to risk in osteoporosis. This study was carried out to identify bone density risk factors affecting women's BMD, and to analyze the relationship of age, between BMD and menopause, BMI, blood pressure lifestyle and dietary habits for bone health by physical measurement and questionnaires. The study subjects, 128 women living in Seoul, were divided into 4 age group; 30~39 years (17), 40~49 years (54) and 50~59 years (36) and 60~69 years (21). There were significant differences in mean height, BMI, systolic blood pressure, menache and menopause age and menopause ratio and BMD T-score among the 4 age groups. BHD was significantly decreased according to increasing age and BMI and menopause. The rate of BMD risk subjects was significantly different increasing with age and BMI. The rate of risk group were 0%, 13%, 22.2% and 71.4%, by age groups and 0%, 16.2%, 33.3% and 52.9% by BMI respectively. BMD of menopause groups was significantly decreased from 1.23 (40 years) to 1.34 (60 years). p < 0.001. Also systolic blood pressure were significantly increased from 116.5 mmHg (30 years) to 130.81 mmHg (60 years). The T-score of normal group also decreased significantly from 1.27 to 0.13 (60years) with age. There were significant negative correlation between BMD and age (r = -0.409) menopause (r = -0.346), BMI (r = -0.218) systolic blood pressure (r = -0.193), salty taste eating out (r = -0.185) (p < 0.05). There were significant positive correlation between BMD and meat fish and walking time. In conclusion, bone density decreased with age. Most of the 50 years' subjects were in risk group. BMI, menopause, systolic blood pressure, frequency alcohol consuming. To prevent osteoporosis, over 40 years needed to be educated to maintain normal weight and the improvement of eating and living habits.

Controlling the quality of indoor air is important in order to maintain a healthy life. In this study, we investigated the correlation between the hazardous substance concentration of indoor air and circulation based on different ventilation methods in the apartment, which is one of the representative housing types in Korea. As target substances, we considered the hazardous substances which are generated during the cooking process and radon gas which is originated from building materials. We measured the concentrations of carbon dioxide and fine particles in relation to type of food and ventilation methods in order to determine the change in the concentration levels of hazardous substances which are generated during the cooking process. On the other hand, we measured the concentration of radon gas before and after letting fresh air into a room through windows in order to determine the change in the concentration level of radon gas which is originated from building materials. The results show that turning on the ventilation fan plays a major role in reducing the concentration levels of hazardous substances in the kitchen, and that it is more effective to turn on the ventilation fan during cooking than after cooking to prevent the diffusion of hazardous materials produced by cooking through the indoor air. Also, the results indicate that letting fresh air into a room through windows more than one time a day is necessary to reduce the concentration level of radon gas in the room to safe concentration range.

The purpose of this study was to study the intake of heavy metals such af arsenic, lead and cobalt and the relationship of dietary heavy metals with serum iron, topper, and zinc, which play important roles in hematopoiesis, in healthy college women living in Choongnam Korea, where we have detected heavy metals (As, Pb, Co) in some marine products in previous studies. The nutritional status of the subjects (35 women) was evaluated by anthropometric measurements, 24-hr dietary recall for 3 days. And 3-day diets (by weighing method) and blood were collected to analyze As, Pb, Co, Fe, Cu, Zn, Hb, Hct, and MCHC. The mean age, height, weight, and BMI were 20 years, 158 cm, 55 kg and 22.42 kg/$m^2$, respectively. The mean daily energy intake was 85.85% of RDA for Koreans. The ratio of energy from carbohydrate, protein, and fat was 60 : 24 : 16. The mean daily intake of heavy metals (As, Pb, Co) was 1.77 mg/day, 75.21 $\mu$g/day and 21.12 $\mu$g/day. And the mean daily intake of iron, copper, and Zinc concentrations were 97, 68, and 92% of normal values. The mean serum heavy metals (As, Pb, Co) were 16.14 $\mu$g/dl, 4.32 $\mu\textrm{g}$/dl and 0.02 $\mu$g/dr, respectively Mean blood levels of Fe, Cu, Zn, Hb, Hct, and MCHC were at normal levels. Dietary heavy metals except Co were not significantly different from serum Fe, Cu, Zn and Hb, Hct, and MCHC. However, there was a tendency toward lower serum concentration of Fe, Hb, Hct, and MCHC in the subjects with higher heavy metals (As) intake. Among heavy metals, only dietary Co showed a significant negative correlation with Hb (p< 0.001) and Hct (p < 0.001).

Folate is important for multiple metabolic processes such as nucleic acid synthesis and interconversions, and cell division. Folate deficiency may be a risk factor for several pathologies, such as neural tube birth defects, dementia, and cardiovascular diseases. The objectives of this study were to estimate folate intakes and plasma concentrations of young children living in Kwangju, Korea. Three consecutive 24-h food recalls and fasting blood samples were obtained from 24 boys and 30 girls, aged 2-6 y, living in Kwangju, Korea. The daily folate intake ($mean{\pm}SD$) of the children was $146.7{\pm}73.6{\mu}g$ dietary folate equivalents. No differences in folate intakes were observed by gender ($p{\geq}0.05$). The mean folate intakes of the 2 and 3 y old groups were significantly lower (p<0.05) than those of 5 and 6 y old groups. Over half of subjects consumed $mean{\pm}SD$) of all subjects was $19.2{\pm}8.7nmol/L$, and there was no significant difference by age nor gender ($p{\geq}0.05$). No significant correlation was observed between folate intakes and plasma folate concentrations. One subjeci (1.9%) in this study had a plasma folate concentration <6.8 nmol/L, which is indicative of folate deficiency. Approximately 24% of subjects had plasma folate concentrations of 6.8-13.4 nmol/L, which is representative of marginal folate status. In conclusion, some young children may have less than adequate folate status in Korea.

Korea's aging population has been remarkably increased. They want to have not only extension of life expectancy but also improving quality of life. To maintain the quality of life, it is essential to have good nutrition. However, nutritional status of elderly in Korea has problems qualitatively and quantitatively. Risk factors for poor nutrition are advanced age, woman, living alone and low economic status. Another risk factor in rural area is season because seasonal changes can affect food intake of elderly. Thus this study surveyed the health status and dietary intakes of elderly by season in rural area. In this study, the elderly were grouped as group 1 {elderly who have one risk factor for chronic diseases (obesity, hypertension, dyslipidemia, diabetes)} and group 2 (elderly who have more than 2 risk factors). Can-Pro 3.0 was used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. Obesity had the highest percentage 62%, followed by hypertension 59.5%, dyslipidemia 21.5% and diabetes 11.6%. Obesity, hypertension, and dyslipidemia were high in winter and WHR, diabetes and anemia were high in summer. Mean intakes of energy and nutrients were less than RI. Nutrients which were changed most by season were vitamin A and Vitamin C. Intakes of calcium and folic acid were less than recommended in summer. The ratio of CPF for carbohydrate was higher and fat was lower than recommended. In conclusion, the nutrient intake of Group 2 was better in quality but Group 1 was better in quantity. Nutrient intakes were poor in summer. In rural area, more careful nutritional assesment and management are needed for aged population, especially in summer.
