To investigate the image, preference, importance and satisfaction of foreign visitors to Korean foods, 220 visitors (male 104, female 115) were surveyed with questionnaires in English and Japanese. To achieve this research purpose, frequency analysis, exploratory factor analysis, t-test, and one way ANOVA was performed using the SPSS 15.0 program. Subjects had various nationality such as Europe/Oceania (24.7%/), Asia (23.3%), Africa (12.8), and North America (39.3). The representative food was kimchi > bibimbop > bulgogi but the most favorite food was bibimbop > kalbi > bulgogi in order. Like this, there are some discrepancies among the food choice, especially in kimchi, so the taste of kimchi should be improved according to the foreigners' taste. The results of the preference about the image get the high grade from those factors; the resonable price of Korean food, the spicy taste, various kinds of food according to the settings of the table, good for the health with excellent taste. Foreigners consider that the cleanliness of food and tableware, the sanitation of the restaurants, the taste of the food and freshness of ingredients are the important factors in Korean food and Korean restaurants. According to these factors, the satisfaction is affected by the attitude of servers > the taste of the food > the freshness of the ingredients > the amount of the food > the atmosphere of the restaurants > the cleanliness of the tableware in order. From the relationship between the importance and the satisfaction, the low grade food should improve the color and styling of the food and be served the appropriate amount of the food. Moreover, it is needed to improve the combining the spices and the ingredients to maintain a balance between strong and delicate flavors and with this, Korean food should be more globalized to promote the development of Korea tourism.

The purpose of this study was to investigate the mutual relationship between food preference and nutrient intake status of high school students, based on the their personal characters which are sex, age, family type, number of family, mother's age, occupation, and school career. 439 students were selected with random stratified cluster sampling method. The study used a self-administrated questionnaire and 24-hour recall method for 5 days as instrument tools. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-Wallis test, ${x^2}-test$ by contingence table, and Spearman's correlation coefficient in non parametric statistical methods. Some of interesting results are as follows : 1. The correlation between sex and the set of characters of mother's age, school career and income is highly significant. However there is no any significant difference on the kinds of job and the types of family. 2. The relation between the preference of main dishes and the nutrient intake show a significant difference except to the noodles. This marks that preference of main dishes shows a direct proportion with the nutrient intakes except for the fat, vitamin A, vitamin C. 3. The preference of animal food marks a direct proportion with the nutrients such as energy, protein, fat, fiber, phosphorus, iron, vitamin $B_{1}$, vitamin $B_{2}$, and niacin 4. The preference of vegetable food gives some influence on the nutrient intake but the preference of soup is insignificant, the preference of Kimchi is in reverse proportion, and the preference of vegetable marks a direct proportion with the nutrient intake. 5. The preference of snacks marks a direct proportion with all kinds of nutrients intake except for the vitamin A, and vitamin C.

지하수위 아래에서의 터널굴착은 지하수 영역의 변화를 초래하게 되고, 지하수의 공급이 충분하게 이루어지지 않는 경우 자유수면의 하강현상이 발생하게 된다. 이러한 거동을 수치 해석적으로 모사하기 위해서는 자유수면위의 불포화토 거동을 포함하는 자유수면의 변화를 고려하기 위한 복잡한 해석 알고리즘을 채택하여야 하고, 불포화 토의 수리거동을 포함하므로 통상 구속흐름조건으로 가정하여 해석하게 된다. 그러나 이 방법은 실제 많은 상황에서 발생하는 지하수위 저하를 고려하지 못하며 지하수위 저하가 터널 및 주변지반의 거동에 어떠한 영향을 미치는지 파악하기 어렵다. 본 연구에서는 비구속 흐름조건하의 지하수위 아래 배수형 터널을 건설하는 경우 지하수 영역의 변화와 이 변화가 터널과 지반에 미치는 영향을 수치 해석적 모델링 방법을 통하여 파악하고, 이를 통상적 해석방법인 구속조건의 흐름과 비교 고찰하였다. 해석결과 지하수위 변화는 지표, 특히 지하수위 상부의 거동에는 지대한 영향을 미칠 수 있지만 터널라이닝 거동은 구속흐름의 경우와 거의 차이가 없는 것으로 나타났다.

This is the precedent study on the modern fashion design using Korean emotions, and its aim is to study the expressions in the modern fashion based on 'Jeong-Jung-Dong' idea from Korean dancing, which implicates the Korean emotion deeply among the artworks and give essence similar to the clothing. 'Jeong-Jung-Dong', a unique idea, in the Korean traditional dancing is the philosophy that involve the paradox expression, 'Movement in Silence,' which represented the emotion of Korean dancing for a long time. The main characteristics deducted in 'Jeong-Jung-Dong' were 1) the incomplete and complete by atypical, 2) the beauty of temperance by symbolism, and 3) amusing mutual relationship. Upon the analysis results of previous studies on the expressions in the modern fashion with 'Jeong-Jung-Dong', they demonstrated the atypical expressed by metaphor, symbolic expression through margin, and mutual relational table by harmony. The analysis of modern fashion expression by 'Jeong-Jung-Dong', which is a philosophical idea in the Korean dancing, could highlight the new way of looking at the clothing and systemize the theory on the Korean emotion to seek the effective expression of artistic features for the culture together with introduction of our unique emotion in the creative design process by understanding of humanitarian and philosophical ideologies to be utilized in the future Fashion Design.

The purpose of this study was to evaluate the effect of the nutrition education on preschool children's nutrition knowledge and behaviors. The study subjects were preschool children attending J kindergarten located in Wonju. Each of the control group and the education group consisted of 49 children and the education group was exposed to nutrition education while the control group did not. The nutrition education intervention lasted 9 weeks weekly basis. The t-test for the homogeneity of each group showed no meaningful difference at the beginning point of nutrition education. After nutrition education a test of nutrition knowledge using picture-questionnaire was carried out by the researcher for the subjects of education group and control group and the caretakers of the education group were offered self-administered questionnaire on the changes in children's dietary behaviors. The results of the study were as follows: 1. Nutrition education intervention showed a meaningful difference in children's understanding nutrition; the kinds and function of food, the relationship between food and body, the function of nutrients and enhanced their idea on hygiene compared to the control group (p < p.005). 2. However, nutrition education intervention made no statistically meaningful difference in children's dietary behaviors such as having breakfast, keeping balanced diet, washing hands before meals, saying "thanks" before and after meals, cleaning the table after meals, brushing teeth after meals and so on. Therefore, we found that it is hard to expect children to correct their dietary behaviors in such a short period of 9 weeks and nutrition education for preschool children should be offered to caretakers at the same time.

The purpose of this study was is to investigate the relationship between transformational leadership in families and psychological well-being and career decision-making self-efficacy. The samples were randomly selected from high school students studying liberal arts in Seoul. 400 survey questionnaires were distributed March 11 through 18, 2010. Among them, 386 completed surveys were utilized as the data for the statistic analyses. SPSS were applied. The main results of the study are as follows. First, adolescent children of mothers with leadership have higher psychological well-being than those from families of mothers without leadership. This has been determined as a result of reviewing the psychological well-being of adolescent children according to their mothers' transformational leadership in the family. Second, the adolescent group with mothers who show transformational leadership in managing the home have higher career decision-making self-efficacy than the group without such mothers. This was determined as a result of reviewing adolescent children's career decision-making self-efficacy according to mother's transformational leadership level in the family. Third, career decision-making self-efficacy according to adolescents' psychological well-being show positive relations by group. That is, adolescents living table lives are more positive about their future. Lastly, when comparing the relative contribution of the mother's transformational leadership in the family and psychological well-being on career decision-making self-efficacy, it has gained more credibility as stage ads. Based on the results, when mothers nurture children with a affection-based autonomy, children gain higher psychological well-being, which leads to firm beliefs about constructive futures. Therefore, for successful and systematic career development, CEO mothers' transformational leadership should serve as its foundation.

XML은 웹을 비롯한 모든 문서들을 표현할 수 있는 데이타 중심 표준 언어이다. XML 기반의 여러 문서 개발 도구들의 등장과 이를 이용한 사유 XML 문서의 증가, XML 문서로의 기존 데이타 변환가속화로 인해, 우리는 대량의 서로 상이한 구조로 표현된 XML 문서들을 가지게 되었으며, 이러한 문서 집합으로부터 원하는 정보를 담은 문서를 추출해 내는 것이 중요해 졌다. 하지만, 기존의 XML 문서에 대한 연구들은 한 개의 대규모 XML 문서나 동일한 구조를 가진 문서들에 대한 저장, 검색에 초점이 맞춰져 있거나. 상이한 구조를 지원하더라도, 구조적인 정보를 이용한 빠른 검색을 지원하지 못하는 단점을 가지고 있었다. 이에, 본 논문에서는 상이한 구조를 가진 문서들에 대해서도 빠른 경로 질의를 제공할 수 있도록 지원하기 위한 새로운 기법으로, 관계형 데이타베이스 시스템을 이용한 새로운 역 인덱스를 제안하였다. 우리는 제안된 기법이 기존의 방법에 비해 높은 성능을 보임을 실험을 통해 확인하였다. 특히, 간접 포함 관계를 포함한 모든 진의에서 논은 성능을 제공함으로서, 상이한 구조를 가진 문서들에 대해 적합한 인덱스 구조임을 보여 주었다.

STATSGO 데이터베이스는 주단위의 토양 특성을 분석하는 데에 있어 효과적인 자료다. 본 연구에서는 GIS 기법을 이용하여 STATSGO로부터 8개 주요 토양 특성을 추출하였다: 함수력(available water capacity), 점토비율, 토양깊이, 사면경사. 지하수위까지의 깊이, 배수 특성, 토성, 투수도, 평균적인 NDVI로부터의 편차로 정의된 가뭄 정도(drought severity)에 대해 앞서 열거한 토양 특성이 미치는 영향을 캔자스 중서부 지역을 대상으로 분석하였다. 연구 결과에 따르면, 분석된 8개 변수 중 7개가 통계적으로 유의한 상관관계를 가진 것으로 나타났는데, 상관계수는 -0.89에서 0.85에 이르렀다. Moderate Resolution Imaging Spectroradiometer(MODIS)로부터 취득된 지표복사열(thermal emission) 자료는 평균 NDVI에 대한 편차로 표현되는 가뭄정도와 통계적으로 유의한 상관관계를 가졌으며, 식물생육기간에 걸친 가뭄지역의 공간적 변화를 잘 나타내었다. 토양수분의 결핍양이 많아질수록, 복사열 시그널 값도 높아지며, 공간적 분포로 볼 때. 상대적으로 건조한 캔자스 서부로부터 증가하여 시간에 따라 점차 그 분포도 변화하였다. 연구결과는 또한 가뭄의 진행단계에 따라 가뭄에 대한 각 토양 변수의 영향도 달라짐을 보여주었다.

Fertility has been declined since 1966 (see Table 1). This fertility reduction was duely caused by age at first marriage, induced abortion and contraceptive practice which has been largely increased in recent years. Although tbe proximate determinant such as induced abortion, age at marriage and breastfeeding can and do have an effect on fertility, the principal cause of the reduction in fertility in Korea during the fertility transition can be supported by correlation between level of fertility and contraceptive prevalence (See Fig. 4). Taking a regression equation between fertility (TER. Y) and prevalence level (X), the total fertility rate in 1984 was estimated as 1.9 and 2.1 based on lenear and expotential function shown as follow; $Y_1$=5.709-0.0549 X and $Y_2$_______80________ 1+e2.433+0.017X ($R^2$=O. 93) ($R^2$=0. 96) Where $Y_1$ and $Y_2$ denote total fertility rates obtained through two equations respectivelly. The peak of contraceptive prevalence was assumdd as 80 percent which is almost upper limit in human society. On the other hand, an observed value of 1984 fertility level obtained from five month period shows 2.1 which is coincident with logistic fitting after the adjustment of response error assumed around 10 to 20 percent, At any rate, fertility of Korean women will have been reached replacement level (2.1) by 1985.Thus policy for family planning program must be reviewed toward the direction of integrated approach particularly with MCH program inasmuch as fertility in Korea has already shown population replacement level that require more good quality of service in family planning and their There must be an advanced level of fertility in Korea because wide use of contraception and induced life abortion and age at marriage will effect modern fertility which shows up and down trend between 2.1 and 1.5 in general.
