This study was conducted to provide information about the behavioral intentions to diet in adolescent females. To explain the behavior intention to diet, a conceptual framework based on the ' Social Support, Control and the Stress Process Model ' and the ' Theory of Reasoned Actio ' was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done by using mean, correlation and multiple regression analysis with the SAS computer program. Subjects were divided into 3 groups-underweight, normal weight, and overweight-according to their current body size. The most powerful influencing factor related to perceived stress -that is dissatisfaction with body image- was the current figure, regardless of current body size. The fatter the current body size, the higher the score for the behavioral intention to diet. In attitude toward the behavior of dieting, the fatter the current figure, the higher the attitude score, and the belief of behavioral outcome was the main decision variable. For the score of the subjective norm, the overweight group was significantly higher than other groups. The influencing factors for the behavioral intention to diet were perceived stress and attitude toward dieting behavior, especially beliefs of behavioral outcome.

This study compares the body sizes of Korean and Mongolian female college students, their perceptions about body size, and body satisfaction based on similar cultural backgrounds. The subjects consisted of 164 Korean students and 171 Mongolian students from March to April, 2008. The age range was 17 to 22 years. We directly measured the body sizes of subjects and examined by questionnaire the degree of body cathexis, perceived body size, and ideal body size. Both Korean and Mongolian college students have similar body measurements but Korean college students have smaller heads, broader and slopped shoulders, and thinner arms and legs. There were insignificant differences in perceived body size for both groups; in particular they perceived that their lower body is fat or thick. However, there were differences in body satisfaction. Both groups had the lowest satisfaction rate for their lower bodies; but in all items, Korean college students had a lower body satisfaction rate than Mongolian college students even though they have thinner arms and legs. Finally, the ideal body style for both groups was a skinny body type, but Korean students preferred a much thinner body type. The body satisfaction rate is greatly affected by the ideal body than the actual body.

The purpose of this study was to compare Korean and Japanese female college students' body sizes, their perceptions about body size, and body satisfaction based on similar cultural background. Subjects consisted of 185 Korean students and 91 Japanese students from October to December, 2000. The age range was 18 to 28 years. We measured body sizes of subjects directly and examined by questionnaire the degree of body cathexis, perceived body size, ideal body size. The results were as followed. 1) Korean women had slimmer silhouette with longer arm and longer leg than Japanese, while Japanese women had more voluminous silhouette with smaller waist circumstance and bigger hip circumstance than Korean. 2) There were not differences between perception about each body size of the Korean women and Japanese women, except arm length. Especially, two groups felt themselves as greater on thigh. 3) There were not differences between satisfaction about body of Korean women and Japanese women, except height. Generally, two groups had lower body satisfaction on each body area, especially on thigh, lower body part, abdomen, hip, and weight. 4) Perception of body size had higher correlation with body satisfaction than actual body size. Lower satisfaction was related to more negative perception of body size. 5) Regarding ideal body size, Korean women pursued bigger height, weight, waist, and hip than Japanese. However, Japanese women pursued bigger bust than Korean. This means that Japanese women pursued more voluminous body silhouette.

This study focused on the comparison of satisfaction with and perception about their bodies by Korean and American women. The respondents included 242 Korean and 145 American female student volunteers, aged 18 to 27, who were enrolled at Kwangju and Catholic University and Cornell University in the United States. The questionnaire was composed of three sections; a body cathexis, perceived body shape-self, perceived body shape-ideal. Twenty items of 30 items showed a significant difference between Korean and American women. Korean student females were more dissatisfied with 20 items than American women. Even though Korean women were smaller in body build than the American women, the Korean women were more negative about their large type, shoulder, hands, arms, hips, neck, face, and skin color than the American women. There were many significant differences between perceived body shape-self and perceived body shape-ideal responses for Korean and American respondents. The exceptions were that a fuller bosom, and longer legs than perceived body shape were desired in both cultures, longer arms were desired by Korean women and darker skin color was desired by American women.

The purpose of this study is to grasp the internet use time that young people use for purposes other than learning purpose, to grasp the perceived status of the youth according to internet use time and to grasp the interrelationships of them. Using the 2016 youth health behavior online survey, the odds ratios and 95% confidence intervals of perceived status according to internet use time were calculated by binary logistic regression analysis. The main results are as follows. In perceived health and perceived oral health the odds ratios of perceived who feel that they are perceived and unhealthy as the time spent using the Internet increased significantly compared to those who did not use the Internet for learning purposes. In the perceived body type, the odds ratio of being overweight increased significantly with longer internet use time. The odds ratios of perceived happiness were 1.19 times (CI = 1.10-1.30) higher than the perceived expectation of unhappiness when using the Internet for over 300 minutes. The use of the internet for a long time other than the purpose of learning may have a negative effect on the health and happiness of the youth, so we think that the recommended time for using the internet is necessary.

Macrophage migration inhibitory fartor (MIF), known as a cytokine, is a multifunctional protein that is ubiquitously expressed in a variety of cells and tissues; however, enzymatic function of MIF still remains elusive in cells. In this study, we assessed details of the tautomerase activity of MIF. We established rapid purification condition for MIF by using pGEX system and compared the L-dopachrome tautomerase activity of GST-MIF, tMIF, and MIF. The results show that GST (glutathione S-transferase)-epitope tag or N-terminal amino acids flanking the essential $P^{2}$ almost completely abrogated L-dopachrome tautomerase activity of MIF. Subsequently, to determine whether the N-terminal tags have effects on oligomerization of MIF, protein cross-linking products were analyzed on $15\%$ SDS-PACE. The result demonstrates that N-terminal tags are dispensable for the formation of MIF's homooligomers. Thus, the results imply that exposure of If containing hydrophobic pocket in the active site is critical for L-dopachrome tautomerase activity of MIF. In addition, our study suggest that the MIF's tautomerase activity might be influenced by interacting with cellular partners.

The Purpose of this study was to investigate college students' attitude toward body weight control, health-related lifestyle and dietary behavior by their perception on body image and obesity index. The subjects were 871 nation- wide college students (330 male and 541 female students) participating in a nutritional education program via internet- A cross-sectional survey was conducted using a self-administered questionnaire via internet. The data were analyzed by a SPSS 10.0 program. Height and weight (p < 0.05), and the distribution of obesity index (p < 0.001) showed significant differences between male and female college students. As for self perception on body image, the necessity of body weight control and the experience of efforts to change the body weight, there were significant differences between male and female college students (p < 0.001). There were significant differences among groups by obesity index in the hours of exercise (p < 0.01), drinking (p < 0.01) and smoking (P < 0.001). As for methods of body weight control, all the groups by obesity index thought that program of body weight control by diet company is the most desirable method. Therefore, we must recognize that it is hard to correct health problems resulting from wrong lifestyle and dietary behavior fixed during college life and prepare a system for college students to obtain correct lifestyle and dietary behavior.

This study was performed to investigate the dietary habits, body weight satisfaction and eating disorder tendencies of female university students in Kyungnam province. Anthropometric measurements, dietary habits, body weight satisfaction, food preferences, disordered eating, and nutrient intakes were assessed in 132 female students at Kaya University. The results were analyzed with $x^2$- and ANOVA tests using the SPSS package program. The average age of the subjects was 20.1 years and average body mass index (BMI) were $21.1\;kg/m^2$. According to BMI, the percentages of students who were underweight, normal weight and overweight by BMI were 21.2, 55.3, and 23.5, respectively. Duration of exercise was significantly different by BMI. Index scores for a mini dietary assessment were significantly higher in the normal and overweight groups than in the underweight group. Scores for sweet, salty, and meat preferences were highest and scores for bean and vegetable preferences were lowest, in the underweight group. Satisfaction for present body weight was lowest, and self-perception of body image and weight control experiences were highest in the overweight group. All subjects in the overweight group wanted to be slim, and those in the normal and underweight groups, preferred to be more slim despite their current body weight being in the normal or below normal range. The percentage of the subjects who were at risk for eating disorders (based on scores from the Eating Attitude Test-26, EAT-$26{\geqq}20$) was 11.3%. Scores for EAT-26 were higher in the overweight group than in the underweight and normal weight groups. Nutrient intakes were not different among the groups. Therefore, dietary habits, taste and food preferences, satisfaction for present body weight, and disordered eating were significantly different according to BMI. These results suggest that overweight female university students need help correcting disordered eating, and nutrition counseling should be established to aid desirable weight control methods. Those who are underweight and normal weight need help establishing proper perceptions of their normal body weight and body image as well as nutrition counseling for health.

IS/IT 분야 실무자가 지니고 있어야 한다고 생각되는 지식과 전문 기술들을 '지식/능력 영역'과 '소프트웨어 전문 기술 영역'으로 구분하여 각각 세부 항목을 명세하였다. 그리고 분류된 두 영역에 대하여 IS/IT 분야 실무자가 생각하는 필요한 지식 및 전문 기술들의 중요도와 IS/IT 전공 교수가 생각하는 IS/IT 실무자에게 필요한 지식 및 전문 기술들의 중요도를 조사하여 두 그룹간의 인식차 비교를 시도하였다. 조사지역은 실무자는 충청지역 및 수도권 지역에 분포하는 SI 업체를 대상으로 이루어 졌다. IS/IT 실무자를 대상으로 한 조사는 실무자 본인의 일장에서 IS/IT 실무자가 갖추어야 된다고 판단되는 지식 및 전문 기술들의 중요도를 측정하였다. 그와 더불어 그들이 수행하는 IS 활동에 대하여 투자한 시간을 기준으로 군집분석을 실시하여 세가지 그룹으로 구분하여 실무자 전체와 세 그룹간의 비교가 가능하도록 조차되었다. 비교 결과, 지식/능력 영역에서는 IS 실무자들이 상대적으로 '하드웨어에 대한 지식', '특정 조직', '운영체제에 대한 지식'에 대해 더 높은 중요도를 부여하고 있는 것으로 나타났다. 소프트웨어 전문 기술 영역에서는 실무자보다 전공교수가 생각하는 중요도가 보편적으로 더 높게 나타났다. 전공 교수는 '프리젠테이션 도구', '객체지향 언어(C++, Java 등)'에 4점 대의 높은 점수를 주어 중요한 것이 무엇인가 하는 인지가 있는 것으로 보이나 실무자 그룹에서는 특별히 중요시 여기는 항목이 명확히 드러나지 않고 보편적인 값이 median 값 주변에 위치하고 있다. 이는 현재 실무자들이 빠르게 변화하고 있는 IS/IT 환경에서 본인의 경력경로 (career path)을 위해 무엇이 중요한 갓인지 아직 명확히 하고 있지 못하는 것으로도 해석이 가능하다. 자세한 비교/분석 및 해석은 현재 진행 중이며, 여러 흥미로운 해석이 가능할 것으로 기대 된다.합형 파괴가 증가하는 경향을 나타내었다. 이상의 결과로, 상아질 접착제의 접착단계/과정이 결합내구성에 영향을 미침을 알 수 있었다. 따라서 접착과정의 단순화가 반드시 접착에 효과적이라고 할 수 없다.는 저작 운동 잔에는 2군에서 Heliomolar가 Pyramid보다 변연적합도가 우수하였고 (p < 0.05) 그 외의 군에서는 유의차가 없었으며, 저작 운동 후에는 모든 군에서 재료간 유의차가 없었다. 각 부위별 변연적합도를 비교하면, 저작 운동 전 Pyramid에서는 교합면 변연에서는 4군이 2군에 비해 높은 변연적합도를 보였고 (p < 0.05), 인접면과 치은면에서는 군 간 유의차를 보이지 않았다.
