The purpose of this study was to investigate the relationship of depression and life-stress by values in Korean university students. Data were collected by structured questionnaires form 212 students by convenient sampling methods from August to November 2011. The type of values were classified into: personal oriented values, 64.6%; social oriented values, 35.4%. There were no significant differences in depression by values. But there were significant differences in frequency of experiences and importance of life-stress by values. Also, there were significant differences for correlation between depression and life-stress by values. These results suggest that for the university student, the nursing strategies should be developed in order to improve ability to reduce life-stress and depression considering such differences by values. Especially, it is necessary to attention in management of stress and depression for students with personal oriented values.

Most traditional databases exploit record-oriented storage model where the attributes of a record are placed contiguously in hard disk to achieve high performance writes. However, for search-mostly datawarehouse systems, column-oriented storage has become a proper model because of its superior read performance. Today, flash memory is largely recognized as the preferred storage media for high-speed database systems. In this paper, we introduce fast column-oriented database model and then propose a new column-aware index management scheme for the high-speed column-oriented datawarehouse system. Our index management scheme which is based on enhanced $B^+$-Tree achieves high search performance by embedded flash index and unused space compression in internal and leaf nodes. Based on the results of the performance evaluation, we conclude that our index management scheme outperforms the traditional scheme in the respect of the search throughput and response time.

The purpose of this study is to understand the decision-making behavior of a mathematics teacher in science academy of Korea by applying the framework of class analysis through the theory of goal-oriented decision-making. To this end, we selected as the participant a mathematics teacher in charge of the class of basic calculus of science high school for the gifted in the metropolitan area, and observed the teacher's lesson. Based on a questionnaire derived from previous studies, we analyzed goals, orientations and resources of the teacher. Research results show that there are certain teaching routines by analyzing the behavior patterns that appear repeatedly in the teacher's lesson. Also we understand that it can be used on goals, orientations and resources of the teacher to adequately explain his teaching routine. In the present study, in particular, it was found to have a similar but partially different routines to the teaching routines shown in the study of Schoenfeld. From these findings, We can derive the implications that the theory of goal-oriented decision making can be suitably used as analytical tool for understanding the behavior of the teacher who pursue a productive interaction in mathematics lesson in Korea.

인간의 생태계를 근본적으로 위협하고 있는 기후변화와 같은 환경오염 문제는 글로벌 경쟁시대의 기업 경영에 있어 강력한 제재요인 중 하나로 관심이 집중되고 있다. 국내에서도 이러한 환경문제가 중요 이슈로 부각되고 있는데, 특히 인류생존에 필수적인 자연환경을 기반으로 사업을 영위하는 농업분야는 더욱 깊은 연관성을 갖는다. 정부는 이러한 농업분야에 대하여 도시와 농촌 간 소득 불균형이나 농촌인구 노령화 등의 문제를 해결하고 미래 성장산업으로 발전시키고자 6차산업화 인증 제도를 시행 중에 있으며 앞으로의 성장이 기대된다. 또한 최근 기업의 환경을 포함하는 사회적 책임활동에 대한 관심이 높아지고 능동적으로 참여하려는 소비자의 특성 변화에 따라 6차산업화 인증을 받은 기업들도 성장하기 위해서는 기업 활동의 근간이 되는 소비자 니즈에 더욱 집중할 필요성이 제기되므로 기업의 새로운 성장 방안으로써 고객과 환경에 집중하고 사회적 가치를 창출해 나가야 할 것으로 추측된다. 이에 본 연구에서는 6차산업화 인증을 받은 기업을 대상으로 고객지향성과 경영성과 간 관계에서 환경지향성이 조절효과를 가지는 지를 밝히고자 하였으며, 연구 결과 고객지향성은 경영성과에 정(+)의 영향을 미치며, 이러한 관계 속에서 환경지향성은 정(+)의 조절효과를 가진다는 것을 실증하였다. 즉, 6차산업화 인증기업이 경영성과를 제고시키기 위해서는 소비자의 변화와 기업이 수행해야 할 사회적 책임을 명확히 인식하여, 소비자 니즈기반의 환경보존과 같은 사회적 가치를 창출하고 공유하려는 친환경 지향적인 새로운 혁신전략을 수립하고 실행해 나가야 할 것이며 이를 통해 지속적인 성장을 견인할 수 있을 것이다.

Recently, the object-oriented design is the major paradigm for software development. Most systems are following this paradigm, but the past studies for a video conversation domain were not based on full-scale object-oriented design. Thus, this paper presents an systematical architecture design using UML for a video conversation system that is well-known and has high rate of usefulness. It analysis a video conversation system that has much demand of service as systematical functional/non-functional requirements, and the object-oriented design applying '4+1 View Model' guarantees the reusability of a component and makes it possible to extend a system by adding components as needed. Consequently, it is expected that the components of video conversation system designed by this paper will be useful the other video conversation systems and will be expanded to web environment.

The value of XML as electronic documents is increasing nowadays. The XML document has properties of semistructured data. It can be modeled as object-oriented model which can be easily adapted by object-oriented database. For storing XML documents to conventional database system, extracting schema information from the DTD of a XML document has been studied for several years. In this paper we store XML documents into object-oriented database, which preserve the semantics of the documents. We can store and query by OQL and make applications by C++ and make applications by C++ binding which is the access method of object-oriented database. Therefore, existing database applications can be used without modification.

The concepts of class, inheritance and information hicing and so on provide the great strengthes of object-oriented languages, but they also introduce diffculties in porfram analysis and understanding. Particulary, it is move difficult to umderstand the dyamic aspects than the static ones of object-oriented programs. The dyamicaspects can be understood by recognizing the event's reciprocal action among the classes. In this paper, it will be supplied to the reprecentation of event abstraction which is useful for understanding the object-oriented programs.And the clustering concept with the events will be applied to abstract the events. By clustering the events, user can get the information about function of the classes and the reteival of the class library.
