A new GA-based methodology using information granules is suggested for the construction of fuzzy classifiers. The proposed scheme consists of three steps: selection of information granules, construction of the associated fuzzy sets, and tuning of the fuzzy rules. First, the genetic algorithm (GA) is applied to the development of the adequate information granules. The fuzzy sets are then constructed from the analysis of the developed information granules. An interpretable fuzzy classifier is designed by using the constructed fuzzy sets. Finally, the GA is utilized for tuning of the fuzzy rules, which can enhance the classification performance on the misclassified data (e.g., data with the strange pattern or on the boundaries of the classes). To show the effectiveness of the proposed method, an example, the classification of the Iris data, is provided.

공정과 공사비는 건설사업의 관리에 매우 중요한 두 가지 축으로써, 이들을 통합 관리하려는 많은 노력이 진행중이나, 많은 어려움을 겪고있는 상황이다 내역체계의 특성으로 인해, 국내의 경우는 내역과 공정체계의 두 가지 축을 중심으로 건설사업정보를 통합 관리할 수 있다. 본 연구에서는 지방국토관리청의 도로공사를 중심으로 내역체계와 공정체계를 연계 활용할 수 있는 방안을 제시하고 있으며, 이를 위해, 위해 도로공사 현장 사례를 분석하고, 설문조사를 통하여 문제점을 분석하고, 이를 개선하기 위해 통합건설정보분류체계를 기반으로 시설물별 공통WBS와 부위별 수량산출서를 작성하는 방안을 제시하고 있다. 이러한 방안은공정과 내역의 연계활용뿐만 아니라, 타 정보와의 연계 활용의 기반을 제공할 수 있다.

시설물이 건설되는 생애주기의 전 과정에서 파생되는 방대한 정보는 저장 ${\cdot}$ 가공 ${\cdot}$ 교환을 필요로 하며, 이는 모든 분야에 적용된다. 또한, 기술의 진보로 인해 정보의 취합 ${\cdot}$ 접근방법 ${\cdot}$ 교환이 빈번하게 파생되고 있으며, 건설분야에 종사하는 실무자들의 자재정보획득 절차의 효율성 및 용이한 접근성에 대한 요구도 증대되고 있는 실정이기 때문에, 이를 해소하기 위한 활용성 및 확장성 ${\cdot}$ 표준성을 기반으로 한 건설자재 분류체계는 필수 불가결한 요소로 부각되고 있다. 그러므로 본 연구에서는 건설자재 분류체계의 국제표준성을 확보하고자 ISO기준에 대한 검토를 선행하여으며, 건설실무자들의 활용성 증대를 위한 건설 공정별 분류형식을 자재분류체계에 접목하고자 하였다. 이를 위해 국제표준 및 전자정보화를 위해 개발된 국제 통합분류체계인 OmniClass의 상세분석을 기반으로 건설공정별 분류인 Table 22와 UniClass의 상품 및 자재부분을 적용한 Table 23, 35, 41을 비교하여 건설자재 분류체계의 확장성 및 표준성을 확립하고자 하였다. 또한, 향후 전자상거래를 통한 사용성 및 국제호환성을 확보하기 위하여 국제상품분류(UN/SPSC)의 소성코드체계 접목도 시도하였다.

Constructing the national inventory that can be used as a tool to identify and assess existing or potential contamination is necessary for efficiently managing the soil and groundwater contamination. In order to start this construction, the first step is how we define and classify potential contamination sources of soil and groundwater. After selecting the basic classification model of contamination sources from developed countries, we suggested the classification and list of the potential contamination sources of soil and groundwater which are appropriate for specific conditions of South Korea. In addition, we investigated several databases to confirm the existence of available data sources and then examined established attribute data through chemical accident response information system (CARIS) and water information system (WIS) in National Institute of Environmental Research and mine geographic information system (MGIS) in Mine Reclamation Corporation. All sorts of attribute data in the existing databases can be utilized as significant assessment factors for determining the management priority of potential contamination sources in the future. Therefore, it is required the expanded investigation of additional database sources and the continual modification so that the classification system of potential contamination sources can be improved.

Disaster management system should be built for minimizing damage factor that affects to construction facility from natural disaster. It could be classified by three categories such as disaster prevention, damage survey and recovery phases. For an integrated disaster management system, a disaster information classification system(DICS) is necessary for the reasonable disaster information management. This study suggests an integrated DICS that includes disaster type classification, facility type classification and information type classification for disaster management service. The applicability of suggested DICS is verified by railway facility and the research result could be used as a basic information system for national disaster management system.

This paper presents a fundamental study to establish a standardization system of the Construction Continuous Acquisition and Life-cycle Support(CALS). A state of the art in standardization of the Construction CALS is reviewed to find some defects in developing CALS system in construction industry. It is analyzed that three major parts were needed to set up a standardization system for the Construction CALS. Firstly, the range of Construction CALS standardization is set up to identifying Construction CALS and defining the standards and standardization. Secondly, the strategy to carry out more effectively in Construction CALS standardization and make the relationship of the concerned system presented here can be used to establish the Construction CALS standardization system. In addition, the spread and application device are proposed to use Construction CALS standards at public institution and construction related companies. Conclusively, a classification of the Construction CALS standards was proposed and some objects to be standardized were represented in that. Results studied in this paper will provide the primary information and basic model to develop a guideline for standardization of the Construction CALS.

While science and technology information service portals and heterogeneous databases produced in Korea and other countries are integrated, methods of connecting the unique classification systems applied to each database have been studied. Results of technologists' research, such as, journal articles, patent specifications, and research reports, are organically related to each other. In this case, if the most basic and meaningful classification systems are not connected, it is difficult to achieve interoperability of the information and thus not easy to implement meaningful science technology information services through information convergence. This study aims to address the aforementioned issue by analyzing mapping systems between classification systems in order to design a structure to connect a variety of classification systems used in the academic information database of the Korea Institute of Science and Technology Information, which provides science and technology information portal service. This study also aims to design a mapping system for the classification systems to be applied to actual science and technology information services and information management systems.

This study is under doing to suggest application manual using assembling reference plane design & standard finish material basis upon material classification code as a tool of a linkage between building design and construction standarization in order to enlarge the applicability of house building material that is produced by the module plant. We can say the goal of building standardization intend not only the improvement of construction productibility but also guarantee of subsequent performance through automatization basis upon informationalization of building design. For a etabilishing of this condition, it is neccessary to link the standardization's result of material--design--construction field. According to this neccessity, we are going to suggest information factor that can make relative business manager easily approach to the standardization practical task.
