For the reliable prediction of spatial geotechnical data, a procedure to build the Geotechnical Information System (GTIS) based on geo-knowledge within the frame of GIS technology was developed by introducing a couple of new concepts of the extended area containing the study area and the additional site visit for acquiring surface geological data. To build the GTIS for Gyeongju as the case study of regional model application, intensive site investigations and pre-existing geotechnical data collections were performed and additional site visit was also carried out for acquiring surface geo-layer data in accordance with the developed procedure. Within the GTIS based on geo-knowledge for Gyeongiu area, the spatially distributed geo-layers across the extended area were predicted using the geostatistical kriging method and those for the study area were extracted. Furthermore, the spatial distribution maps for the thickess of geo-layers and the depth to bedrock were constructed for the practical use in geotechnical field. It was evaluated that the GTIS based on geo-knowledge developed in this study is superior to the conventional geotechnical GIS in terms of both the standard deviation and the geological expert judgment.

Instruments used for this study included those used by Kim and Lee and revised and complemented by this researcher to measure the knowledge of AIDS and those by Yun and Lee revised and complemented by the researcher to measure the attitude of AIDS. For data analysis, it measured technical statistics, t-test, ANOVA, and Pearson's correlation coefficient using SPSS/PC 12.0. Results : The results of this study are summarized as follows. 1. The whole knowledge of AIDS the subjects had scored 58.9 and their average attitude scored $3.78(1{\pm}25)$. 2. In the degree of knowledge of AIDS depending on general characteristics and health-related characteristics of the subjects, it was found that the students at the department of emergency medical showed higher knowledge(t=3.638, p=.001) and positive attitude of AIDS(t=3.330, p=.001) compared to students at other majors. 3. In the degree of knowledge of AIDS depending on AIDS-related education, subjects who had experienced AIDS education(t=1.973, p=.050), those with the experience of theory education(F=4.057, p=.008), those who felt the necessity of AIDS education(t=4.588, p=.000), and those who were willing to take part in AIDS education(t=2.898, p=.004) showed higher know1edge of AIDS. In the attitude of AIDS, subjects with theory-oriented AIDS education(F=3.012, p=.032), those who felt the necessity of AIDS education(t=2.445, p=.015), and those who were willing to take part in AIDS education(t=2.379, p=.018) showed positive attitude of AIDS education. 4. As the knowledge of AIDS the subjects was higher(r=.329, p=.000), they showed more positive attitude of AIDS and it meant that there was positive correlations. Conclusion : Consequently, systematic, concrete and continuous education of AIDS suitable to the requirements of college students is needed to induce changes of their knowledge and attitude of AIDS and for this, AIDS education program which can be used properly by the developmental stages of college students who belong to late adolescence should be developed in the field of school and if possible, curriculum of sex education including AIDS education should be established in all departments of college.

Ubiquitous computing requires timely supply of contextual information in order to upgrade decision quality. In this sense, this study is aimed at proposing a multi-dynamic decision support system for highly ill-structured problems. Especially, it is very important for decision makers in the ubiquitous computing to coordinate conflicts among local goals and global goal harmoniously. The proposed Multi-Dynamic Decision Support System (MDDSS) is basically composed of both central structure and distributed structure, in which central structure supports multi objects decision making and distributed structure supports individual decision making. Its hybrid architecture consists of decision processor, multi-agent controller and intelligent knowledge management processor. Decision processor provides decision support using contexts which come from individual agents. Multi-agent controller coordinates tension among multi agents to resolve conflicts among them. Meanwhile, intelligent knowledge management processor manages knowledge to support decision making such as rules, knowledge, cases and so on. To prove the validity of the proposed MDDSS, we applied it to an u-fulfillment problem system in which many kinds of decision makers exist trying to satisfy their own objectives, and timely adjustment of action strategy is required. Therefore, the u-fulfillment problem is a highly ill-structured problem. We proved its effectiveness with the aid of multi-agent simulation comprising 60 customers and 10 vehicles under three experimental modes.

As the service industry is advancing, the meaning of service innovation has been evolved. Recently, service innovation embraces all creative activities about service offering or relevant to service offerings and emphasizes the importance of customers in innovation process as a key driver. The innovation in services is often the result from a collaborative process between KIBS firms and client firms. Many researchers have pointed out about how the KIBS firms drive the innovation through service. In spite of the importance of service innovation, previous studies did not address the questions about what kinds of factors affect service innovation in KIBS firms still remain, or what are the effects of different knowledge on the innovation process. Therefore, the purpose of this study is to investigate the effect of the interactivity that KIBS firms have with their customers on various types of innovations in KIBS firms. Interactivity has been touted to be the most important starting point for and the basis of service innovations. This study also examines the effect of knowledge types (tacit or explicit) on the relationship between interactivity and service innovation. To test the proposed hypotheses, we developed measurement items and distributed survey questionnaires to domestic companies. 230 survey questionnaires were distributed and 81 were returned among which 76 were usable. The results of this study show that interactivity may be a significant indicator of innovation within KIBS firms. It also represents that the effect of knowledge types on the relationship between interactivity and innovation. These results indicate that KIBS firms need to improve the various activities of interaction with customers for innovation. This study provides a blueprint to further investigation of the critical role of service in service science perspectives.

The Election paradigm can be used as a building block in many practical problems such as group communication, atomic commit and replicated data management where a protocol coordinator might be useful. The problem has been widely studied in the research community since one reason for this wide interest is that many distributed protocols need an election protocol. However, despite its usefulness, to our knowledge there is no work that has been devoted to this problem in a mobile ad hoc computing environment. Mobile ad hoc systems are more prone to failures than conventional distributed systems. Solving election in such an environment requires from a set of mobile nodes to choose a unique node as a leader based on its priority despite failures or disconnections of mobile nodes. In this paper, we describe a solution to the election problem from mobile ad hoc computing systems. This solution is based on the Group Membership Detection algorithm.

The design of distrbuted systems is difficult to achieve as the execution patterns of distrbuted systems are typically more complex than those of non- distributed systems. Thus, research toward the development of design methods for distributed systems is quitely needed. As object-oriented systems and distrbuted systems share similar properties, the combination of these two is somehow natural. In this work, a design of distributed systems is introduced. The goal of the method in this paper is to provide assistance to the process of specifying a formal object- oriented specification from graphical representation specification inputs such as data flow diagrams, state transition diagrams and Petri nets. It addresses the extraction of objects, operations and reationshipsfrom the problem domain with emphasis on the specification of the characteristics of distributed systems. This object identification method is supported by a knowledge base that provides for the automated analysis and reasoning about objects and their relationsships. The final object model is represented in a format which provides a formal mechanism for reprsenting the object information.

As most of the data configuration at distributed environment has a tree structure following the hierarchical classification, relative data retrieve is limited. Among these data, the data stored in a database has a problem in integration and efficient retrieve. Accordingly, we suggest the system that uses XMDR for distributed database integration and links XMDR to TopicMap for efficient retrieve of knowledge expressed hierarchically. We proposes a plan for efficient integration retrieve through using the XMDR which is composed of Meta Semantic Ontology, Instance Semantic Ontology and meta location, solves data heterogeneity and metadata heterogeneity problem and integrates them, and replaces the occurrence of the TopicMap with the Meta Location of the XMDR, which expresses the resource location of TopicMap by linking Meta Semantic Ontology and Instance Semantic Ontology of XMDR to the TopicMap.
