In this work, aiming at improvement of growth processes for the bulk GaAs single crystals, efforts have been made first in investigate thermodynamic properties of the Ga and As system and second to suggest that bulk GaAs crystals could be grown in principle with the single temperature zone only by determining the excess arsenic charge as a function of growth conditions. During crystal growth, this will be evaporized inside the growth chamber to induce the required inner pressure, instead of aesenic vapor pressure in the double temperature zone method, so as to be in equilibrium with the method, growth experiments have been prepared and carried out for dopes and undoped GaAs crystals with the newly built Bridgman system which was designed according to this principle. To compare the results to those of the double temperature zone method, the same numbers of GaAs crystals have been grown with both processes and all of them were characterized in single crystallinity, lattice defects and electrical properties. Especially, the relationship between growth conditions and crystal quality was discussed from the viewpoint of growth peculiarities with this method.

Purpose: The purpose of present study was to explore relationship between physical activity (PA) behavior and self-efficacy among older Korean-Americans (OKAs) based on reviewing major theories that are used to understand PA behavior, particularly as they relate to older adults within sociocultural contexts. Methods: 151 OKAs, living in California, were recruited and interviewed once. Self-efficacy and PA level were measured by Exercise Self-Efficacy Scale, Community Healthy Activities Model Program for Seniors (K-CHAMPS) questionnaire, respectively. Results: 82.8% of OKA women and 72.4% of OKA men had relatively low ($38.8{\pm}29.3$) self-efficacy related to PA. Exercise self-efficacy was statistically significant and positively associated with frequency for moderate and greater PA (r = 0.25, p < .01), frequency for all listed PA (r = 0.21, p < .05), caloric expenditure for moderate and greater PA (r = 0.23, p < .01), and caloric expenditure for all listed PA (r = 0.31, p < .01). Conclusion: Social Cognitive Theory including self-efficacy can provide insight about how to shape strategies that encourage OKAs to adhere to regular PA because it focuses on environmental as well as personal factors. Increased efforts are needed to understand the other factors associated with being active in OKAs.

Objectives: This study investigated the relationship between adolescents' suicidal ideation and their physical health conditions to contribute to lower suicide rates among adolescents. Methods: Secondary analysis of 2108 high school students of $10^{th}$ grade was conducted using the Korean Child and Youth Panel survey in 2013. The association between suicidal ideation and socio-demographic and health characteristics were analyzed using Chi-square tests and regression models. Results: Adolescents' physical health conditions were significantly related to suicidal ideation. In particular, rhinitis and various symptoms such as feeling feverish, low appetite, feeling of nausea, stomachache while studying, and sleeping problem showed statistically significant relationships with suicidal ideation (P < .05). Furthermore, the higher frequency of diseases and body symptoms increases the rate of suicidal ideation. Considering socio-economic characteristics, family structure was also important. Conclusions: Physical health condition is a major contributor to adolescent's suicidal ideation. results suggest that improving social support system for adolescents' physical health conditions across family and school may be important in suicide prevention efforts.

This study sought to explore how SMEs are utilizing EC. Drawing on existing research on IT and EC related field, this study presented the framework of EC utilization level and analyzed its affecting factors in the point of organizational perspectives; strategy and competency. The impact of EC utilization on firm performance was also examined by employing BSC. Structural equation model was applied to test the relationships among the theoretical constructs with data from 171 SMEs. The results showed that the rate of EC utilization in SMEs is growing quite rapidly. However, manufacturing related firms still remain at a lower level compared to service related firms. As for the two affecting factors of EC utilization level, it was found that the level of EC utilization appeared to be driven not by strategy but by competency. This result implicates that EC utilization in SMEs doesn't reach to strategic purpose yet, while it is dependent on firm's competency. As far as the impact of EC utilization on firm performance, the study showed that the level of EC utilization has significant relationship with all perspectives performance indicators of BSC. This study can provide the managers with current EC utilization pattern and the guidelines as to where to put the efforts in the EC utilization and how to get an effective EC utilization strategy in the future.

본 연구는 서울 소재의 A사이버 대학에서 2002년 1학기부터 2005년 1학기까지의 누적입학생 가운데 제적, 자퇴한 중도탈락생의 배경변인을 조사하고 설문을 통해 사이버대학에서의 중도탈락의 원인을 알아보았다. 학습시간의 부족과 경제적 어려움이 가장 큰 원인으로 지적되었으나, 온라인교육에의 부적응과 사이버대학의 인지도에 대한 불안감도 적지 않은 학생들에게 중도탈락의 원인이 되었다. 특히 온라인교육에의 부적응이나 사이버대학의 인지도에 대한 불안감이 중도탈락의 원인으로 되었던 학생들은 다른 학생이나 교수와의 상호작용 부족을 온라인 학습의 가장 큰 어려움으로 꼽았다. 따라서 사이버대학의 중도탈락을 줄이기 위해서는 보다 효과적인 학습전략의 개발이나 등록금 지원 외에도 학생 상호간, 학생-교수 간의 상호작용 증대를 통하여 소속감을 고취하고 온라인 학습의 어려움을 나누는 노력이 필요한 것으로 드러났다.

The purpose of this study is to reinterpretate the history of nursing and health care from the view-point of post-structuralism. It has been emphasized that the development of modern health care has been due to the progressive efforts of medicine and to medical discoveries. Medicine has dominated the history of health care rather than nursing or other health professions. The present study adopts the post-structural method by Foucault, which tries to unite language and knowledge. Foucault examines "the institutionalization of knowledge and the power exerted thereby, with special reference to the devices of social regulation and their function over the madness, the disease, the crime, and the sexuality. " The concept of power in Foucault's writing is that it is exerted spontaneously in verbal behaviors of individuals through knowledge of everyday life such as definition of body or mind, sexuality and relationship of family. Therefore as to the problem of power, this study tries to understand the meaning of the health care history through an analysis of the formation of medical discourse. In order to have authority in a power relation, the medical professional asserts that medical discourse is the most scientific knowledge. The authority of medical professionals can be reinforced by the fact that male medical professionals outnumber female. Devaluation of nursing care is reinforced by the medicine which has the legitimate authority through use of the political skills.
