Generalized intuitionistic fuzzy soft set theory, proposed by Park et al. [Journal of Korean Institute of Intelligent Systems 21(3) (2011) 389-394], has been regarded as an effective mathematical tool to deal with uncertainties. In this paper, we prove that certain De Margan's law hold in generalized intuitionistic fuzzy soft set theory with respect to union and intersection operations on generalized intuitionistic fuzzy soft sets. We discuss the basic properties of operations on generalized intuitionistic fuzzy soft sets such as necessity and possibility. Moreover, we illustrate their interconnections between each other.

The purpose of this study is to draw safe environmental project factors for enhancing the safety of children in peripheral space around children's park and suggest environmental project measures for peripheral spaces around children's parks, based on the survey of children's park users' consciousness on peripheral spaces. Physical space range for this study was limited to low-rise housing area wihtin the radius of 250m, as peripheral spaces around children's parks in which children's playgrounds were built. In addition, the target areas for examining users' consciousness on peripheral spaces around children's parks were selected according to following criteria. 1)areas with highter portion of children; 2) those with higher portion of single-family houses/multi-housing/tenement houses, which constitute low-rise housing areas; and 3) those with higher safety accident rate of children, which was measured based on criminal and traffic accidents. The finding are as follows: first, users' consciousness on safety accidents that are likely to occur in peripheral spaces around children's parks was examined to show that there is most prominent difference between satisfaction and necessity. This result suggests that users are clearly conscious of the necessity of environmental improvement rather than the satisfaction with the current peripheral environment around children's park.; second, for the difference between satisfaction with and necessity of environmental project factors for access/boundary spaces around children's pakrs, there is most significant difference between the satisfaction with and the necessity of establishment of facilities against illegal parking for clear visibility of community roads, for access spaces, and the separate establishment of bicycle racks around main entry into parks, for boundary spaces. Users' necessity of the establishment of them is judged to be derived from the fact that the safety of children and even adults is threatened, because bicycles invaded into the deep inside of children parks. This study analyzed a correlation between satisfaction and necessity through factor and IPA analysis, and should be initially considenred if the future environmental improvement project would be conducted to promote safe environment in peripheral spaces around children's parks in the future. It will be necessary to provide practical environmental project factors through a field investigation.

There is a controversy over the necessity of information intermediaries in virtual market. This study tried to suggest several reasons why they would still flourish in virtual market. It also tried to find out their roles and to forecast their role changes in the future on the basis of Delphi analysis. Though an exploratory study, this can shed some lights on the future studies related to information intermediaries and virtual market.

This study aims to inspect national security consciousness of marriage migrant women, and to figure out factors which affect on awareness of national security. Based on this, this study also suggests a way to build up national security of marriage migrant women. As the result of the factors on security situation, there were several things which are necessity of education, trust in the army and government, positivity toward North Korea and so on, while necessity of education, trust in the army and government, national pride and positivity toward North Korea were on the awareness of national security. There are three ways of building up national security consciousness of marriage migrant women. First, security education is needed to be in the social adjustment program of marriage migrant women. Secondly, concern on security is required to them. Third, a necessity of production on security education material is demanded for marriage migrant women.

In our country, most of the wood resources are imported. We faced a continuous rising of wood price by export country's some conditions and excess rising of transport charge, also a shortage of structural size members. In these situation, recycling or reuse of wood residues and wastes under wood processing industry, building construction and demolition is not a option but a prerequisite. In our country, there is a dearth of data on recycling or reuse of wood residues and wastes, so the investigation on the necessity of recycling or reuse of wood residues and wastes was conducted by using the foreign data and documents. First of all, fields and actual conditions for the domestic wood processing industry were surveyed. Then, kinds and signification of wood residues and wastes were organized. Later, the necessity and the signification of recycling or reuse of wood residues were investigated, and postulations for effective recycling and reuse were suggested. Above all, the necessity of grading standards for reuse or recycling and some important consideration for developing grading standards were emphasized. At last, foreign research tendencies and some applications on recycling or reuse of wood residues and wastes were supplemented.

Method: The design of the study is a narrative investigation-research. The objectives of the study composed of 288 RNs having more than a three-year-experience, working for the university oriental medicine hospital. The tool of the study comprised of 194 questionnaires with the reliability of Cronbach's ${\alpha}=.95$. The data were collected from Dec. 11. 2002 to Feb. 20, 2003 and computerized by SPSS program. Result: The necessity of oriental nursing intervention of nurses working in the oriental hospital showed 3.60 measured by 5-scale-measurement, 2.69 in knowledge and .24 in practice measured by 1-scale-measurement. Conclusion: The oriental nursing intervention on site showed high necessity, moderate knowledge and low practice recommending a continuous education comprised of regular nursing education and in-service program.

휴대폰은 통화, 문자메시지의 기본적인 기능뿐만 아니라, 1000만화소 디지털카메라, MP3, MP4, Blue-tooth, 지상위성DMB 화상통화 등의 최첨단 멀티미디어 기능들이 추가된 컨버전스 제품으로 자리잡고 있다. 이러한 많은 기능을 포함하고 있는 휴대폰이 사용자에게 편의성을 제공하고 있지만, 한편으로는 복합적인 기능들의 제공으로 인한 경제적인 부담감을 가중시키는 결과를 초래하고 있기도 하다. 이러한 점을 인지하여, 본 연구에서는 연령대별로 20대, 30대, 50대, 세 그룹을 선정하여 설문조사를 통해 사용자 입장에서의 휴대폰의 기능별 사용빈도와 필요성에 대해 조사하였다. 그 결과, 휴대폰의 기능별 시용 빈도와 필요성 인식은 세 그룹이 뚜렷하게 그 차이를 보였고, 20대와 30대, 50대뿐만 아니라 다른 연령대별 사용자도 그 차이가 두드러지게 나타날 것이라 예측된다. 모든 사용자의 요구를 충족시켜 주는 휴대폰을 개발하는 데는 어려움이 다를 것이다. 하지만 연령별, 성별, 세대별, 지역별 다른 감성을 가지고 있는 사용자 등 여러 측면으로 사용자층을 분류하여 각 분류에 맞는 요소별로 연구가 진행된다면 모든 사용자의 욕구를 만족시킬 수 있는 휴대폰을 개발하는데 어려움을 줄일 수 있을 것이다.
