To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.

The purpose of this experimental study is to investigate the validity of code equation and table to calculate the reduction coefficient for effective net area in the limit state design code of steel structure and offer the basic research data for the effective net area of tee shape members in tension. The experimental tests were performed by loading the specimens through the flange with high strength bolt. Length of connection, number of bolt and the eccentricity are the parameters in test. According to result, the failure loads in test is less than predicted loads and it well showed when the predicted loads are based on reduction coefficient of the table in code. The lateral buckling of stem occurred in the members with big eccentricity and it reduce the failure loads. Therefore, we thought that an additional tests and research on the factors of effective net area is required.

The purpose of this study was to contribute to the establishment of quality improvement program of farm products and processed food, and to provide the direction of consumer education. A survey was conducted to figure out the differences in the consumer perception of farm products and processed foods according to age group and education level. From the citizens in Tague area, 509 housewives were selected as sample subjects by stratified random sampling procedure. It appeared the main criteria for purchasing farm products was significantly different among age group. Most of consumers(84.5%) thought that food safety of farm products did not belong to safe level. The way to distinguish imported farm products was significantly different among education level. While most of consumers(79.4%) check up the place of origin, the tendency was significantly different among education level. Higher educated group utilized labelling system for the place of origin more often than others to distinguish foreign products. Perception on the farm-brand processed food products was significantly different among age group and education level : it appeared that the younger age group and higher educated group tended to purchase more farm-brand processed food products than other groups.

Abstract This study was intended to investigate the relationship of zinc intake and urinary excretion in adult women. Information on the dietary zinc intake for the consecutive 5 days was collected using weighing method for nine healthy women. Urinary zinc excretion during the same period was also measured. In order to figure out the difference of zinc intake due to dietary assessment methodology, dietary intake was measured by weighing method for three days. At the same time, the meals subjects consumed each day were collected to analyze daily zinc intake of each subject. Average zinc intake for 5 consecutive days was 5.9±0.6mg, which was equivalent to 49% of Korean Recommended Dietary Allowances(RDA). Average urinary zinc excretion during the same period was 0.31±0.18mg, When mean dietary zinc intake was assessed by using weighing method for 3 consecutive days, it was 5.7±1.2mg which was equivalent to 48% of Korean RDA. However, average dietary zinc intake from collected food sample was 6.3±1.8mg by chemical analysis. Based on dietary zinc intake and urinary zinc, we concluded zinc status of adult female participated in this study was marginally deficient.

This study was conducted to investigate the relationship of dietary intake of calcium and food habit. The data were collected by cross-sectional surveys on 124 preschool children aged 4 to 6 years in Daegu. Dietary intakes were measured by food record method for two days. Dietary habit and calcium status of preschool children were compared by food habit. Average daily energy intake was 1357.7 kcal in children having unbalanced food habit, while it was 1501.5 kcal in children having balanced food habit. There were significant differences in average intake of carbohydrate, fiber, and vitamin b_(6) between balanced and unbalanced food habit group. Calcium intake was below the level of 7th Recommended Dietary Allowances for Korean. Dietary Variety Score(DVS) of children with unbalanced diet was lower than children with balanced diet(p<0.05). Urinary calcium excretion was not significantly related to calcium intake level. Based on these results, it is necessary to incorporate the message of balanced food habit to achieve the optimal growth and nutritional adequacy during early growth period of children.

Literature suggest a relationship between trace elements status and diabetic mellitus. This study was intended to examine the zinc and copper status of diabetic patients. Subjects who participated in this study 79 type H diabetic patients and 77 normal adults. The mean of diabetic duration was 9 years. The mean age of diabetic patients and control group was 57.4 years and 55.2 years, respectively. Zinc and copper intake was measured by food record and food frequency method. Urinary zinc and copper was assessed. There was no significant difference of zinc and copper intake between diabetic patients and control group. Urinary zinc and copper of diabetic patients was significantly higher than control group. It appeared that the longer the diabetic duration, the lower the zinc intake. We concluded that dietary information to increase zinc intake should be included for nutrient education of diabetic patients.

식이 변화측정을 위한 방법 및 타당성에 관한 검토

식이성 만성질환의 예방 차원에서 개인 및 집단의 일상적인 식이 섭취량과 그 변화 추이를 정확히 측정할 수 있는 방법에 대한 요구도는 점차 높아지고 있는 반면에 식이 변화를 측정하는 방법은 아직 확립되어 있지 못하다. 이러한 방법을 설정하기 위해서는 식이 변화라는 개념을 구체화시키는 작업이 선행되어야 할 것이다. 식이 변화를 구성하는 요인들은 과거로부터 지속되어 유지되는 식습관과 전통적인 식습관의 상실, 그리고 새롭게 형성되어 추가된 식습관으로 요약되며 그 변화는 점진적이다. 개개인의 식습관은 단기적인 측면에서의 일일 식습관과 장기적인 식습관, 식품에 대한 신념 등으로 구성된다. 기존의 식습관 연구와 관련된 문헌들에서 식이 변화 측정 방법으로 많이 사용되어 온 것은 식품 섭취빈도법이지만 이 방법으로는 식사를 구성하는 주요부분이 아닌 다른 식습관요인들의 변화는 측정하기 어렵다는 문제점이 지적되고 있으며 특정 인구집단별로 식품 섭취를 동일하게 측정할 수 있는가에 대해서도 타당성이나 신뢰도가 검증되지 않았다. 식품신념의 측정은 더욱 복잡하고 표준화하기 어렵다. 식사회상법은 일상적인 식습관의 부차적인 부분을 단편적으로 파악하는데 유용한 방법으로 사용될 수 있다. 따라서 식이 변화를 측정하기 위한 설문은 여러 방법들의 한계점들이 극복될 수 있도록 작성되어야 하며 식습관을 결정하는 사회적 문화적 요인들도 반영되어야 할 것이다. 식품 섭취빈도법으로 개개인이나 특정 인구집단의 식이 변화를 예견하거나 정확히 진단할 수 있기 위해서는 임상 영양학과 사회과학의 학제적 연구를 통한 많은 보완이 요청된다.
