The purpose of this study was to develop a new test instrument based on AAAS Benchmarks for Science Literacy, to assess k-12 students' progress in understanding nature of science (NOS). A total of 276 items were developed including 33 items for grade k-2, 36 items for grade 3-5, 78 items for grade 6-8 and 129 items for grade 9-12 and they were reviewed for validity and reliability. Key ideas that were the foundation of test items were extended, sophisticated and enriched according to the grade level. The general score of this test represents a student's cognitive state about an understanding of NOS. The result of this test can be expected to give some useful information for follow-up investigations, improving instructional design, and conducting further studies.

The concept of globalization has emerged as a powerful paradigmatic concept in explaining many far-reaching economic, social, and cultural transformations in many parts of the world. Globalization can be defined as all the multi-dimensional process by which peoples of the world are incorporated into a global society. The drives of globalization are the tools of modern technology and the free market economy. The purpose of this paper is to understand globalization as a modern context for mission and how it has influenced the Korean church. This paper argues that globalization is not only opportunities for Christian mission but also obstacles against it. This paper discusses some benefits and obstacles to mission. For example, in an age of globalization more and more people can have an opportunity to hear the Gospel message, however, it makes more difficult for them to be disciples. Globalization encourages the context to foster the privatization of Christian faith. The paper suggests some future tasks for the Korean church in an age of globalization: the development of partnership, faith community, worldwide and communal sense of responsibility, and Christian civil society movements. It is hoped that the Korean church will contribute to the globalization of Christian gospel in the future, by embracing the global vision, one Kingdom of God under Jesus Christ.

This longitudinal study of CVA patients has two parts: the first with 50 subjects and the second with 24 subjects. The first part of study shows that in making a prognosis of the early stage of CVA, the factor of visual neglect is most critical. The second part suggested that I-ADL is a better criteria than ADL for long-term CVA patients. 1) In the first study, the 50 subjects, hospitalized in the Department of Rehabilitation Medicine, Korea University Hospital from January 1998 to December 1999, were divided by the result of their MVPT (Motor Free Visual Perception Test) into two groups: one with visual neglect and the other with no visual neglect. In terms of ADL (Activities of Daily Living), the group with visual neglect significantly scored less that the group with no visual neglect. This result strongly supports the hypothesis that the factor of visual neglect is closely related with the CVA patients’ progress of ADL. 2) After two years, the follow-up study on remaining 24 clients (4 deceased, 22 unreachable) has been conducted in an attempt to identify any significant differences of the progress of ADL and I-ADL (Instrumental Activities of Daily Living) between two groups: neglect and neglect-free group. At this time, the ADL of both groups have remarkably improved with no significant difference between groups. However, both groups still scored significantly low in I-ADL. 3) These results lead us to the conclusion that only in the early rehabilitation period, the factor of visual neglect is very useful to predict a prognosis of the CVA patients. In addition, it is reasonable to suppose that rehabilitation for the chronic CVA patients should be guided by I-ADL rather than ADL.

The purpose of this paper is to solve the problem that is occuring in assembly process and to progress the productivity by process analysis methods for manu-open and closed model(DWV-20/25DRG), and auto-open and cloesd model(DWV-20/25/DRA)-ventilation fan. Also, this paper is studied by data of ＇D＇ company's product.

본 연구에서는 접초피로에 있어서 균열의 발생, 진전 등의 관찰을 위해, 균열의 발생, 진전 등이 2차원적으로 되어 시험편측면에서 관찰이 가능한 평판 ring형 시험편을 이용하여 반복수 증대에 따른 균열의 발생, 진전과정을 조사하였다. 그 결과 pitting, flaking형 파손의 초기손상은 접촉면하의 내부에 생기는 접촉면에 평행방향의 균열에 의해 일어나며, 이 균열은 그 방향 밀 파면형태에 의해 접촉응력이 접촉면에 평행방향의 전단응력성분에 의한 모드 ll 피로진전과의 차는 중첩부하된 압축응력의 유무라고 생각되며, 이 가저에 근거로 하여 재료고유의 모드 ll 피로균열진전특성을 구할 수 있는 장치를 개발하였다. 이 장치를 이용하여 알루미륨합금 및 공구강에 대한 da/dN-δk ll 관계의 시험결과를 얻었다.

Super-inflation driven by dilaton/moduli kinetic energy is naturally realized in compactified string theory. Discussed are selected topics of recent development in string inflationary cosmology: kinematics of super-inflation, graceful exit triggered by quantum back-reaction, and classical and quantum power spectra of density and metric perturbations.
