조개추출물분말, 해물조미베이스, 라면분말수프, 정어리추출물분말 등 조미분말식품에 대한 TL 검지방법의 적용가능성을 확인하였다. 이들 시료의 방사선 조사선량과 TL response 간의 $R^2$는0.5966 이상을 보여 주었고, 특히 라면수프는 0.9500 이상의 상관계수를 보이면서 방사선 조사선량이 증가할수록 TL intensity도 증가하였다. 따라서 라면수프 시료를 대상으로 re-irradiation step에 의한 TL response의 검증을 실시하였고, 미지시료의 검지에 필요한 역치(threshold value)를 측정하였다. 이때 비조사 시료의 역치는 최고 1.37 이하였고, 감마선 조사시료(2.5 kGy) 역치는 최저 6.06 이상이였다. 그리고 1.37과 6.06 사이의 역치를 나타내는 미지시료는 재조사하여 방사선 조사유무를 검지하였고, 검지시료의 호기성 전세균의 수를 측정함으로써 검지 결과를 검증하였다. Blind test의 일환으로 실시한 미지시료 검지실험에서는 본 실험에서 설정한 역치의 적용으로 총 167개 시료(감마선 82, 전자선 85)의 방사선 조사유무를 정확하게 확인할 수 있었다. 방사선 조사선량을 예측하기 위하여 3가지 예측모델식을 설정하고 조사선량을 예측하여 본 결과, 2차회귀식이 가장 적합하였으나 실제 조사선량과는 상당한 오차를 보였다.

Adequate nutrients intake and regular eating habit are so important for the students to develop physical and mental health, and they contribute significantly for the development of intellectual capacity. The intake of simple sugar contained in the processed foods is known to have been related not only with such physical problems as obesity and diabetes but also with hyperactivity during growing period. This study analysed the effects of carbohydrate processed snacks on the middle school students' emotional intelligence and intended to demonstrate the correlation and the influence of the foods. The subjects of this study were 476 the 1st grade middle school students sampled from two public middle schools of Gyeonggi Province, Korea. Questionnaire contained 47 questions including the kinds of sugar containing processed foods, the frequency of intake, the frequency of normal diet, and the emotional test. All data obtained in this study were processed by SAS 8.2 program. 77.9% of the students had snacks more than once a day and the favored foods were in the order of bread, cookies, fruit, milk and dairy products, flour foods, ramen and ice cream. Less of the sugar contained processed snacks consumed high emotional intelligence showed(p<0.001). And low intake of carbohydrate processed snacks linked with having more regular meals and the higher levels of emotional intelligence. There was no gender difference in consuming simple sugar containing processed foods, however, out of these foods, carbonated drinks, ramen and pizza affected significantly the emotional intelligence of the male students. It was found that sugar contained processed snacks affect the eating habits like meal skipping and the emotional intelligence. It is determined that the effects of carbohydrate processed snacks on emotional intelligence can not be denied.

Objectives: The purpose of this study was to examine mothers' eating behavior and salty taste and its relationship to their preschool children's eating behaviors. Methods: This survey was conducted by self-report after getting permission from sixty one mothers who had preschool children. The questionnaire was focused on mothers' salty test and salt-related eating behavior of both mothers and their preschool children. Results: Comparison of eating behavior score between mother and their preschoolers showed that mothers' score was lower than their preschoolers' one. Salty foods with high preference and intake frequency by mothers and preschoolers were 'salted dry fish, stock fish' and 'soup, stew, noodle soup'. In addition, there were strong positive correlations between preference and intake frequency on most of the salty food items. Intake of Ramen soup was significantly different (p < 0.001) between the two groups. Preschoolers ate less ramen soup compared to their mothers. Conclusions: Overall results showed that preschoolers' dietary behavior was better than the mothers' one. However, preschoolers' dietary behavior was significantly influenced by their mothers. Therefore, mothers should have an appropriate eating behavior in order to have a positive influence on their children's eating habits. In addition, the results suggested that proper nutrition education is needed for mothers of preschool children.

BACKGROUND/OBJECTIVES: The association between dietary patterns and depression has been reported but the results have been inconsistent. This study was conducted to investigate the association between dietary patterns and depression in middle-aged Korean adults. SUBJECTS/METHODS: The participants were selected from a community-based cohort, a subset of the Korean Genome and Epidemiology Study. Depression was assessed using the Korean version of the Beck Depression Inventory (BDI) and those with a BDI score ${\geq}16$ were defined as having depression. The subjects' food intakes over the year preceding the survey were estimated by using a validated semi-quantitative food frequency questionnaire. Dietary patterns were identified by using factor analysis. Multiple logistic regression was used to assess the association of dietary pattern with depression. RESULTS: Among 3,388 participants, 448 (13.2%) were identified as having depression. We identified two major dietary patterns: 'Healthy' dietary pattern was characterized by high intakes of vegetables, soybeans, mushroom, seaweeds, white fish, shellfish and fruits and a low intake of white rice. 'Unhealthy' dietary pattern was characterized by high intakes of white rice, meats, ramen, noodles, bread and coffee and a low intake of rice with other grains. Compared with subjects in the lowest quartiles, those in the highest quartiles of the healthy dietary pattern had a significantly lower odds ratio (OR = 0.59, 95% CI: 0.42-0.82, P for trend = 0.0037) after adjusting for potential confounders. In contrast, the unhealthy dietary pattern was negatively associated with depression (OR = 1.65, 95% CI: 1.19-2.28, P for trend = 0.0021). CONCLUSION: This results suggest that a healthy dietary pattern (rich in vegetables, soybeans, mushroom, seaweeds, white fish, shellfish, and fruits) is associated with low risk of depression. Whereas an unhealthy dietary pattern (rich in white rice, meats, ramen, noodles, bread, and coffee) is associated with a high risk of depression in middle-aged Korean adults.

Under the huge seismic loads, there are too many risks about which high-rise buildings lost their lateral stiffness caused by plasticity on frame members. Because of earthquake is important cause to bring the collapes countinue to human's life, many reports examined these phenomenons in various angles. And some of them reported the high possibility about building collapse by deformation concentrations under huge earthquakes. For preventing these phenomenons, researchers suggest some items-such as adding damping devices or strengthen their ductility or stifness. This report suggests choose the method of strengthen building stiffness and suggests the alternative designs using high strength steel-SM570TMC, and provides the results of time-history analysis about the alternative designs for investigation.

Recently, a lot of consumers in the United States are trying to find out the diverse Asian foods due to the raw material used,sauce,flavor,taste, and cooking philosophy. Asian fare has boomed up in the past decades at restaurants and retail food markets. These phenomena are considered to continue since many Americans become more cautious for health since they believe the traditional Asian foods are better for health than European, Latin, and traditional American diets. The increase of Asian population in America also induce the increased consumption of Asian foods, and those who traveled and tasted Asian foods during their journey want to take Asian foods after back home. Several sauces including gochujang, ramen, and seaweed snack are examples of Asian foods consumed in a large quantity. Many Asian food and material suppliers are trying to pioneer and penetrate American food market with exotic multifaceted Asian cuisine.
