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.

The purpose of this study was to review the Japanese home care service and analyse the necessity for the home care service and the team approaching. The subjects of this study were 23 Korean students who visited on the Japanese home n due to the curriculum of university. The data were collected from sep. 1 to nov. 30, 1999. The main results of this study were as follows : 1. There was consisted of some nurses, physical therapists, medical doctors, occupational therapists as a team of home care service. They visited patients as multidisciplinary team. 2. The qualities of service was good, and the attitude of patient was positive. 3. There was necessity for rehabilitation home care service in Korea. 4. There was necessity for team work through the rehabilitation home care service in Korea.

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.

Mobile phone becomes composite product which the high technological multimedia functions of a Digital camera, MP3, MP4, Blue-tooth, DMB over basic functions of a calling and 3M3. By the view of user, many functions give a heavy burden rather than supporting convenient function itself because it is complex for user to use it. We want to evaluate how users feel using mobile phone according to age, comparing use frequency and necessity. So survey is tried to figure out the difference between use frequency and necessity by dividing three groups into 20s and 30s and 50s. As a result, difference of use frequency and necessity for functions of mobile phone between 20s and 30s and 50s. And the other users have the difference. Consequently, mobile phone development according to age is necessary to satisfy user's desire, evaluating elements research of user preference. We hope this paper can contribute to mobile phone development as a basic guidance.
