The design of a 16 tesla/ 45mm bore superconducting magnet is presented. The system consists of an 8.2 tesla(at 4.2K) outer NbTi coil with a bore I.D. of 261mm, a winding O.D. of 453mm and the length of 430mm which is connected in series with a 5.6 tesla(at 4.2K) middle and a 4.7 tesla(at 4.2K) inner insert coil constructed of multifilamentary $Nb_{3}Sn$. The middle and inner insert coil will be reacted after winding. Also, epoxy impregnation will be accomplished at $Nb_{3}Sn$ coils using a low viscosity crack resistant epoxy which is forced into the coil with a series of vacuum and over atmosphere pressure cycle.

Purpose: This study is a descriptive correlation study to identify how factors such as motivation to learn, school adaptation, self-control, and self-esteem influence the degree of Internet game addiction and to provide basic data for nursing interventions for male middle school students. Methods: The subjects of this study were 418 male students in lst, 2nd and 3rd grade at three middle schools located in Ulsan. Data were collected from May 1, 2011 to May 31, 2011 and analyzed through descriptive statistical methods, such as the t-test, ANOVA, Sheffe's test, Pearson correlation coefficient and multiple regression analysis, via SPSS 18.0 program. The study's structured questionnaire was composed of 25 items of 'the Motivation to Learn Scale', 41 items of 'the School Adaptation Scale', 20 items of 'the Self-Control Scale', 10 items of 'the Self-esteem Scale', and 20 items of 'the Internet Game Addiction Scale'. Results: 163 students (39.0%) belonged to the non-addiction group while 255 students (61.0%) fell into the addiction risk group. The addiction risk group showed a higher degree of addiction than ones in the non-addiction group. The addiction risk group's average scores for motivation to learn, school adaptation, self-control, and self-esteem were lower than those of the non-addiction group. The statistically significant factors (p<.05) that increase the chance of addiction were grade, family atmosphere, self-control, trading of online game items, and the amount of time playing online games. Conclusion: On the basis of the findings of this study, it is suggested that; qualitative research on the routes of addiction be conducted to find out ways to prevent and nurse addicted students; considering the fact that the average age of Internet users is getting lower and lower, a study targeting primary school students be implemented; since the influences of the variables covered in this study turned out to be relatively low, other factors, especially environmental factors, should also be investigated.

Purpose: The purpose of this study was to examine the effects of being aware of the physical and psychosocial environment of the school on subjective feeling of happiness in Korean middle and high school students. Methods: The data of "Health and lifestyle Survey (2019)" conducted by the National Youth Policy Institute were analyzed after receiving approval though the website. A total of 5,311 middle and high school students were included in the analysis. Descriptive statistics, t-test, one-way ANOVA, pearson correlation, and multiple regression analysis were executed using SAS 9.4. Results: The mean score of subjective feeling of happiness was 6.92±0.56 out of 10. From the univariate analysis, the more positive the perception of the physical school environment was, such as classrooms, restrooms, exercise facilities, catering facilities, health facilities, other school facilities and school uniform, the higher the subjective feeling of happiness was (p for all <.001). In addition, the psychosocial environment of the school was significantly related to the happiness of adolescents (p<.001). After controlling for gender, school level, school grade, socio-economic status, and stress, positive perception of classrooms (B=0.04, p<.001), catering facilities (B=0.01, p=.021), health facilities (B=0.08, p<.001), and the psychosocial environment of the school (B=0.18, p<.001) was significantly associated with happiness of the students. Conclusion: Positive perception of the school environment was found to increase happiness in adolescents. Therefore, efforts should be made to make classrooms, catering facilities, and health facilities a pleasant space as well as to create a school atmosphere that values health.

남녀 중학생들의 섭식의 형태와 신경증적 경향과의 연관성을 알아보고자 1993년 대구시내 모 중학교 3학년 학생 419명(남 : 187명, 여 : 232명)을 대상으로 섭식태도 척도, Middlesex Hospital Questionnaire 및 Zung의 자가평가 우울척도를 사용하여 조사한 결과 다음과 같은 결론을 얻었다. 체중의 과소에 따른 성적은 유의하지 않았다. 남학생과 여학생을 비교할때 여학생의 경우 모든 척도에서 유의하게 높은 점수를 보였다(p<0.05). 섭식태도척도는 Middlesex Hospital Questionnaire와 Zung의 자가평가 우울척도와 유의한 상관관계를 보였다(p<0.05). 정신사회적 요인 중 남녀학생 모두에게 유의하게 높은 접수를 보인 요인은 현재 및 미래 자아상에 불만인 경우 (각각 p<10.05, p<0.05) 현재 및 주위 환경에 불만인 경우(p<0.05)이었다. 남학생에서 유의하게 높은 접수를 보인 요인은 현재 대인관계에 있어서 불만족인 경우(p<0.05)이었으며, 여학생에서는 용돈 중 61-90%를 먹는데 사용하는 경우(p<0.05), 가족간의 관계가 불만족(p<0.05) 또는 보통인 경우(p<0.05), 성장 환경에 불만족인 경우(p<0.05), 과거 자아상에 대해 불만족인 경우(p<0.05) 및 현재 부모와의 관계에서 불만족인 경우(p<0.05)이었다.

In the Western Civilization you can clearly see the change in the architectural system. In the 19th Century many of arcitectural style resurrected in the appearance of style revival. And each of the Style's appropriateness and exactness were very complicatedly discussed. After the middle of 19th Century a series of morality movement which showed an expectation for a historical revival started to show declining atmosphere. To architects at the periods more universal formation seeking and new surpassing style pursuing logic has exacted which care from very different from the past During this period a question were brought up about architecture ornamental rightness and appropriateness. As each of the architects had a saying about the ornament was recognized as important part of architect. On this bases this study's purpose is finding out whst is the maeaning and content of G.Semper's "Bekleidungstheorie"

The purpose of this study is to make clear the identity of Korean traditional housing. And I'm trying to search characteristics of boundary in Korean traditional housing. In this study, I have analyzed boundary of ‘Gwan-gajung’. It is constructed on a square shaped plan, there is an elegant middle court, and a counter-roofed shrine house in the rear of the inner building. In this study, the definition of boundary is made based on what has been perceived as the proper structure, whose characteristics can be described in terms of openness, inside and outside parts and orientation. As a critical factor to spatial qualities, boundary is closely related with the connection and disconnection, background and atmosphere, and inferior and superior relations and hierarchical order from the view of space. The result of study is like followings. The characteristics of boundary in Korean traditional housing is 1. one way direction of penetrability, 2. having the face and the back 3. orientation 4. duplication.

The East Asian monsoon is generally accompanied with the quasi-stationary front along the northern and northwestern periphery of the subtropical anticyclone in the boundary zone of the polar cold air mass and the tropical warm air mass. The rainy season in Korea has been called as Changma since the middle of 1500s. In meteorology, the rainy season with the quasi-stationary front, the Changma front, during the early summer has been defined as the Changma since 1905. The difference of meaning on Changma between meteorologists and the general public sometime does give a confusion. For example, the heavy rainfall event after the retreat of Changma is recognized as Changma by the general public, but not by most of meteorologists. The decision of the onset and retreat dates of Changma among the meteorologists is also ambiguous because of different viewpoints on the definition of Changma. In this study we survey the etymology and definition of Changma.

A ball-shape alumina arc-tube for low-wattage lamp was developed by the PIM process. An ultra high purity translucentgrade alumina powder was used. In injection molding process, a hot-runner type mold was developed. The translucent-grade alumina powder was extremely sensitive to contamination so that the injection molding condition and atmosphere control in the furnace should be taken care of with extreme caution. Contamination sources were pinpointed with EPMA. The arc-tube was molded in half and two halves were bonded in the middle by a new bonding technique at room temperature developed in this study.
