The new class of $Gd_5(Si_xGe_{1-x})_4$ compounds undergoes a simultaneous magnetic/structural phase transition giving a high level of strain that can be induced either by change in temperature or by application of a magnetic field. Profound changes of structural, magnetic, and electronic changes occur in the $Gd_5(Si_xGe_{1-x})_4$ system lead to extreme behavior of the material such as the giant magnetocaloric effect, colossal magnetostriction, and giant magnetoresistance. These unique material characters can be utilized for various applications including magnetic solid refrigerants, sensors, and actuators.

본 연구에서는 개인의 불안 애착 성향이 사회적 일체감을 강조한 소구방식의 기부광고 선호에 미치는 영향력과 해당 과정을 매개하는 소속 욕구 요인을 실험을 통해 확인하고자 하였다. 실험 참가자들은 각각 개인적 소구 조건의 기부광고와 사회적 소구 조건의 기부광고에 노출된 후 광고에 대한 태도와 기부의도를 보고하였다. 두 차례의 실험 결과, 소비자의 불안 애착 정도가 클수록 사회적 일체감을 강조하는 소구방식의 기부 광고에 보다 긍정적인 태도를 보이는 것으로 나타났다. 또한, 소비자의 불안 애착과 사회적 소구방식의 기부광고 사이에서 소속에 대한 욕구가 매개하는 효과도 유의한 것으로 검증되었다. 즉, 기부를 촉구하는 광고 메시지를 구성할 때 개인의 불안정 애착 성향을 고려함으로서 소구력을 높일 수 있음을 입증하였다. 본 연구의 결과는 성인의 애착 불안이 기부 의도를 이끌어내는 하나의 준거로 작용할 수 있다는 사실을 발견하고, 불안정 애착자들이 기부행위에 기대하는 감정적 편익의 가치를 인식하도록 도움으로서 윤리적 소비 분야에서의 경제 주체간 상호 이익관계 구축 이슈를 제시하고 있다. 또한 사회적 소구 방식의 기부 광고 메시지에 대한 소비자의 태도, 호의를 점화를 통해 조정할 수 있음을 입증하였다는 점에서 학문적, 실무적 시사점을 제공한다.

Objectives: This study identified how personal characteristics, family environment, governmental policy for the prevention and cessation of smoking might influence on adolescent smoking. Methods: This study used data from the 2006 Korea Youth Risk Behavior Web-based Survey of 71,404 middle school and high school students, giving a response rate of 90.9%. We selected 61,508 adolescents subjects of the final analysis without missing data on independent variables and dependent variables which are used in this study. This study used $\chi^2$ tests and logistic regression models. Variables were added to the regression model in three groups using a hierarchical approach.Results: Adolescents were significantly more likely to become current smokers if they were boys, were in a higher grade, and had lower academic achievement. Adolescents experiencing stress and depression were associated with increased risk of current smoking. Adolescents with single parents or students of non-living with parents comparing with students of living with parents showed the high possibility of smoking. Lower father's education was associated with increased likelihood of current smoking. Adolescents who were exposed to smoking at home were more likely to smoke. Adolescents without contacting with the antismoking media campaign was associated with increased likelihood of current smoking. Conclusion: Promoting antismoking media campaigns targeted at adolescent is required, and the smoking prevention education which are proper for subjects are required. Proper plans which could decrease the exposure of secondhand smoking should be established.

모델체킹은 검증하려는 대상 시스템의 동작 모델이, 그 시스템이 만족해야 할 성질을 만족시키는지를, 시스템의 상태공간을 검사해 봄으로써 알아보는 정형 검증 기법의 하나이다. 이러한 모델체킹 기법을 병렬 객체지향 시스템에 적용하기 위해 기존의 모델체커인 SPIN에서 지원하는 모델링 언어인 Promela를 병렬객체지향 개념을 추가하여 확장한 언어인 APromela를 제안하였다. 이는 Promela가 프로세스를 단위로 하는 병렬성만을 지원하는데 반해, 액터 모델에 기반한 객체지향 병렬성을 지원한다. 또한 우리는 이 언어로 작성된 모델을 자동으로 Promela로 변환하는 규칙을 제안하였다. 이를 통해, 기존의 모델체커를 이용해 병렬 객체지향 시스템의 검증을 수행할 수 있다. 이 언어의 응용으로 UML 로 기술된 명세의 검증을 수행하는 과정을 제시하였다.

At present, the Department of Energy (DOE) in Unite State are directing the efforts of developing accident tolerant fuel (ATF) technology. As the first barrier of nuclear fuel system, the material selection of fuel rod cladding for ATFs is a basic but very significant issue for the development of this concept. The advanced cladding is attractive for providing much stronger oxidation resistance and better in-pile behavior under sever accident conditions (such as SBO, LOCA) for giving more coping time and, of course, at least an equivalent performance under normal condition. In recent years, many researches on in-plie or out-pile physical properties of some suggested cladding materials have been conducted to solve this material selection problem. Base on published literatures, this paper introduced relevant research backgrounds, objectives, research institutions and their progresses on several main potential claddings include triplex SiC, FeCrAl and MAX phase material Ti3SiC2. The physical properties of these claddings for their application in ATF area are also reviewed in thermohydraulic and mechanical view for better understanding and simulating the behaviors of these new claddings. While most of important data are available from publications, there are still many relevant properties are lacking for the evaluations.

As population concentration, high-rise, and high-density progresses amid rapid industrialization and urbanization in Korea, green areas in the city have decreased significantly and the natural environment has deteriorated day by day due to various development projects. In order to cope with these social changes, many studies related to park and green areas have been conducted, but in the case of Gwangju-si, only studies on green areas such as vegetation structures, street facilities, and recreation forests have been conducted on park green areas. The situation is not losing. Therefore, in this study, a survey was conducted on Gwangju citizens to understand the usage behavior and satisfaction of park green areas, and to provide basic data for future park development and reorganization. As a result, first, to induce a variety of static and dynamic activities in order to increase the park satisfaction of Gwangju citizens, it is possible to create a park that has not been formed as soon as possible, and by planning programs with various themes. Second, it is necessary to expand green space services in marginalized areas by creating water streams, flower pots, and rooftop greening around the lives of Gwangju citizens, and create park green spaces with themes using cultural and historical resources for each administrative district. Third, in order to solve the dry landscape in some urban areas, it is necessary to establish a three-dimensional landscape plan by creating a variety of green areas such as potted plants, green areas, and street trees, and by giving functions of park green areas such as expanding leisure and convenience facilities.
