This research is aimed at contributing to the education related to library space planning by carrying out a questionnaire survey on the recognition of libraries related to the education related to library space planning and supporting libraries in charge of library space planning through the result analysis. The following is a report on the direction and improvement of education based on a survey on the impact on subjects related to library space planning. First of all, education on library space planning should be centered on practical work of space planning. Second, the participation of librarians in the planning process of library space must be considered important for smooth communication with users and experts. Third, it is expected to be necessary to plan education methods and curriculums related to the planning of library space according to the size and budget of the library. Fourth, active public relations regarding library space planning education is necessary. The active promotion of library space education will emphasize the participation and necessity of librarians in space practice, and further contribute to the operation of libraries and the provision of library services to users.

Recently, Green Business/IT becomes very important for management of company, because there are many new regulations about the environment protection, especially to reduce green house effect. The purpose of this research is to investigate present situation of Korean manufacturing industry about the Introduction of Green Business/IT. For the people who is in charge of the decision whether to Introduce Green Business/IT or not, this paper aim to provide some useful findings. We made a research framework consisting of 5Ps (Philosophy, Partner, Process, Product, Public) from literature review, then we found that almost all of the companies in manufacturing industry prepare for the regulations by introducing and using Green Business/IT concepts. There are some differences between production goods industry and consumer's goods industry. Also we found that there are a lot of relationships with recognition level and planning level. The higher the level of profitability, the lower the level of preparing social responsibility. This means there are two opposite perspectives(profitability, social responsibility). Therefore organizations who are adopting Green Business IT/should strive for harmony of sight.

Computer Aided Process Planning (CAPP) plays a key role by linking CAD and CAM. Given CAD data of a part, CAPP has to recognize manufacturing features of the part. Despite the long history of research on feature recognition, its research results have rarely been transferred into industry. One of the reasons lies in the separation of feature recognition and process planning. This paper proposes to integrate the two activities through AI techniques, and presents efforts for manufacturable feature recognition, setup minimization, feature dependency construction, and generation of an optimal machining sequence.

It is increasing scenery created as a result of pine wilt disease. The purpose of this study is to investigate the local resident's awareness against the scenery caused by pine wilt disease in their neighboring area, through the questionnaire investigation. The result showed that more than $40\%$ of the residents are not aware of such scenery in their local area, and about 30% of the residents did not know that those trees were dying. More than $40\%$ of the people do not know of the pine wilt disease as a general argument. Another question showed that the recognition of such scenery depends on the distance of the viewer. General residents don't worry about such scenery in the far distance in fact some of them think those are colored leaves. However, the nearer they see the trees, the higher they have negative feeling against it.

The purpose of this study is to develop planning technique for low carbon rural village planning. planning techniques (169 cases : waterside Technique 87, inland Technique 82) were extracted through a various previous studies and literature. planning techniques of 43 cases for low carbon rural village have been developed by the importance validity evaluation for planning techniques using the Delphi Method. Developed techniques can be utilized to plan low carbon rural village for Sustainable Rural Development. In addition, these techniques will be able to contribute to recognition of the need about low carbon rural village and the development of national green strategy.

The interest and participation of the rural experience is increasing as an alternative for the problems such as the decrease of the agricultural income facing the agriculture and the rural area, the decrease of the population, and the regional stagnation. The rural experience has recently been transformed into a software dimension such as programs and participation activities in the past. In addition, public awareness also positively evaluates agriculture and rural communities as the basis for supporting society and recognition of multiple functions. Furthermore, the intention of the citizen to the earnest village is increasing. The purpose of this study is to analyze the effect of rural experience and customer satisfaction of urban residents on the recognition of return to farm and rural areas. As a result of the analysis, it was found that the characteristics of rural experience had a positive effect on the farming villages by the program, the experience field and the host, and the customer satisfaction had a positive effect on the farming villages. Therefore, it is considered that a systematic approach to the rural experience is needed in the future because the experience of the rural people in the city has a positive effect on the earliest villages.

As a part of development of process planning system for mold die manufaturing, a software system is developed, which recognizes features and extracts parameters of the shape from design data produced by solid modeller. The recognized feature date is fed to process planning and operation planning system. Low level geometry and topology data from commercial CAD system is transformed to high level machining feature data which used to be done by using a dedicated design system. The recognition algorithm is applied to the design data with boundary representation produced by a core modeller ACIS which has object oriented open architecture and is expected to become a common core modeller of next generation CAD system. The algoritm of recognition has been formulated for 21 features on prismatic components, but the feature set can be expanded by adding rules for the additional features.

Solid modeling refers to techniques for unambiguous representations of three-dimensional objects. Feature recognition is a sub-discipline focusing on the design and implementation of algorithms for detecting manufacturing information such as holes, slots, etc. in a solid model. Automated feature recognition has been an active research area in stolid modeling for many years, and is considered to be a critical component for CAD/CAM integration. This paper gives a technical overview of the state of the art in feature recognition research. Rather than giving an exhaustive survey, I focus on the three currently dominant feature recognition technologies: graph-based algorithms, volumetric decomposition techniques, and hint-based geometric reasoning. For each approach, I present a detailed description of the algorithms being employed along with some assessments of the technology. I conclude by outlining important open research and development issues.
