The purpose of this study was to research the perception and concern of university students with regard to well-being, and how these affected their assessment and satisfaction of university dormitory foodservice. Therefore, a survey was administered to 328 college students that use a dormitory foodservice. The results of the survey are as follows: First, the more positive the self-centered and society-centered values in relation to well-being, the greater both the concern and will to practice well-being through the eating well-being foods. Second, the attitude toward well-being food was positively correlated with the taste, amount, temperature, appearance and shape of dishes. Third, unlike the will to practice well-being through the eating well-being foods, the greater the concern about foods of well-being, the more positive was the effect on the general satisfaction with the foodservice. The greater the satisfaction with the attributes of a foodservice had a substantial influence on the general satisfaction with the foods. That is to say, the taste and type of dishes played a key role in the general satisfaction with the foods. Fourth, the concern in relation to foods of well-being had no measurable influence on the decisions with regards to the satisfaction of a foodservice or on the intention to reuse that foodservice. In addition, in relation to the degree of satisfaction with the attributes and use of a foodservice, the taste, type, appearance and shape of dishes had an important impact on the decisions to use and reuse a foodservice. Fifth, the general satisfaction with the meals served by a foodservice operation had a measurable influence on the satisfaction with, and intention to reuse that foodservice.

Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

The cultural tendency based on sharing and cooperation, which has recently been a hot issue, accelerates throughout the world. This study began with a perception that a sharing culture is inherent in urban public spaces. This study aims to conduct a theoretical study of the sharing culture and to analyze the characteristics of the design composition of public spaces. This study selected squares in 16 European cities as cases for analysis. The results are summarized as follows:1)To analyze the design characteristics of public spaces in which a sharing culture is inherent, this study drew the shape and type of planes and sharing elements such as accessibility, symbolism and activity with the squares in the cases. 2)The shape of planes in the squares in the cases has been formed in close relations with the historic meaning and events of the area and the process of the construction of buildings surrounding the square. The squares in the cases were classified into seven plane types, and these squares have developmentally contributed to the formation of a sharing culture as a place for free participation and communication concerning social issues. 3)In the squares in the cases, the weight of road-centered access appears high, and in terms of the construction of human-friendly / environment-friendly infrastructure in the city or judging from the trend of the recent increase of pedestrian-centered plans for public space, it is judged that approaches with a high utilization rate of sidewalk or public transportation would be desirable. 4)Symbolic elements of the square become a device by which citizens can share the historic symbolism, along with artistic inspiration. In addition, by serving as an observatory from which people can take a view of the landscape of the city, it allows visual sharing of the entire city as well as the square. 5)A square is common pool resources in the community, and it is necessary to vitalize that in a direction of increasing the possibility of sharing, through the characteristics and methods of the composition of public design.

Purpose: The purpose of this study was to investigate the relationship between health locus of control(HLOC) and eating behavior in obese middle school girls. Method: The sample consisted of 170 obese middle school girls in Seoul. Result: 1. The average scores of HLOC were HLOC-Internal ; 4.11, HLOC-External ; 2.45, HLOC-Chance ; 2.09. 2. The average scores of eating behavior factors were Disinhibition ; 2.69, Dietary Restraint ; 2.67, Hunger ; 2.55. 3. The HLOC-Internal and eating behavior(dietary restraint and hunger) were correlated positively. The HLOC-Chance and disinhibition was correlated positively. But HLOC-Chance and dietary restraint was correlated negatively. The HLOC-External and eating behavior(dietary restraint, disinhibition and hunger) were correlated positively. 4. There was not a significant difference in HLOC depending on the demographic characteristics(grade, degree of obesity, father & mother's body shape, existence of obese sibling). There were significant differences in HLOC-Internal and HLOC-External according to thinking about oneself who is obese or not. 5. There was not a significant difference in eating behavior depending on the demographic characteristics(grade, degree of obesity, father & mother's body shape, existence of obese sibling, perception of oneself as a obese). Conclusion: This study has shown a correlation between HLOC and eating behavior. As a result of these findings, clinical and school nurses should be involved in management and counselling of obese girls concerning individual health locus of control and eating behavior.

The purpose of this study is to objectify the shape of curvature and average change rate of angular and arched eyebrow makeup. The data for the analysis were the final 336 pieces for the cosmetology students in the whole country. SPSS 20.0 program was used for the collected data, frequency analysis, factor analysis, reliability analysis, and crossover analysis were performed. First, the frequency of the average change rate of eyebrow makeup (angular and arcuate) was analyzed. As a result, the eyebrows suitable for the angled type showed the highest level of 'A-2' and the arched eyebrows had the highest level of 'B-2'. Second, to analyze the important factors of eyebrow makeup, frequency of eyebrows was the most important, followed by the inclination of eyebrows and eyebrow tail. Third, factor analysis and reliability analysis were conducted to examine each dimension of eyebrow makeup perception, and it was derived from three factors including acceptability, aggressiveness, and playability. Fourth, in order to analyze the difference of important factors in the form of the standard eyebrow makeup, the cross - analysis was performed with chi - square test, and it was confirmed that the angular eyebrow makeup showed the most objectivity when the average change rate was 0.29 and the curvature was 0.67. Fifth, arcuate eyebrow makeup showed the most objectivity when the average change rate was 0.57 and curvature was 0.56. The results of this analysis can be used as objective data of aesthetic criteria when designing the eyebrow shape.

국제원유시장 및 경제구조의 변화로 유가충격과 거시경제 간의 전통적 관계가 점차 약화되고 있는 것으로 인식되고 있다. 본 연구는 확률적 변동성으로 가정된 시간-가변 이분산을 갖는 TVP-BVAR모형으로 한국경제에 미친 유가충격의 시간-가변적 효과를 추정하였다. 분석결과, 최근의 통념들과는 달리 시간-가변 표준편차 1단위 크기로 정규화한 유가충격의 효과는 과거에 비해 크게 변하지 않은 것으로 나타났다. 또한 유가충격에 대한 각 시점별 충격반응함수들의 형태도 유사하게 나타나, 충격의 전파경로 역시 크게 변하지 않은 것으로 나타났다. 특히, 유가충격은 국내 경제성장률과 물가상승률의 총 변동을 4~10% 수준에서 설명하는 것으로 나타나, 국내경기변동의 주요 원동력인 것으로 나타났다. 이와 같은 점들은 원유소비의 비중축소 및 에너지고효율 기술보급 등과 같은 경제구조의 변화가 빠르게 진행되고 있으나, 아직까지는 유가충격의 부정적 효과를 상쇄할 만큼 충분한 진전이 이루어지지 못했음을 의미한다. 오히려, 유가충격의 효과에 관한 최근의 통념들은 국제원유시장 및 경제구조의 변화를 반영하지 못하는 유가충격의 정규화방식에 기인하는 것으로 나타났다. 이와 같은 분석결과는 유가충격의 효과를 추정함에 있어 충격규모의 변화를 반영할 수 있는 모형설정과 정규화방식의 중요성을 지적하는 것이다.

본 연구는 곡선의 두 가지 물리적 속성인 파의 개수와 파고의 크기를 매끄러움을 구성하는 두 가지 주요 모수로 가정하고, 매끄러움의 감각에 어떠한 모수가 영향을 미치는지, 나아가 아름다움의 감각과 매끄러움 간 관계를 검증하였다. 이전 연구들 가운데 매끄러움이라는 감각을 곡률 개념을 사용해 정의한 연구는 없었으나 본 연구에서 이를 새로운 방법으로 정의하였다. 연구 재료는 3차 스플라인 곡선을 단면으로 삼아 이를 회전하여 만든 3차원 구체로 파의 개수와 파고의 크기를 각 3개 수준으로 나누어 둘을 조합시킨 9개 유형의 형상을 이용하였다. 9개 유형 가운데 어떠한 형상이 선호되는지 관찰한 결과, 파의 개수가 적은 조건이 가장 선호되었으며 파고의 크기에 따라서는 파고의 크기가 큰 조건이 가장 선호되었다. 다음으로 각 형상에 대해 선호를 측정하는 세 가지 문항과 친숙성 그리고 매끄러움을 평가하였다. 매끄러움의 두 가지 파라미터라 가정한 파의 개수와 파고의 크기를 고정효과로, 참여자 및 개인차 변인들을 확률효과로 설정한 선형 혼합 모형을 통해 분석한 결과 매끄러움 평정 값의 분산의 약 80%가 연구에서 가정한 모형으로 설명되었다. 개체의 물리적 속성의 지각에 성별 등의 개인차 변인의 역할은 확인되지 않았으며 형상의 물리적 속성이 중요하게 작용함을 확인하였다. 스플라인 곡선을 기반으로 만든 객체의 매끄러움의 지각에는 파의 개수보단 파고의 크기가 더 큰 영향을 미치는 경향을 확인할 수 있었다.
