This paper is an exploratory study to investigate the influence of characteristics of local government web-sites on user satisfaction and trust. The objective of this research is to identify the characteristics of local government web-sites influencing on user satisfaction and trust, and determine how they affect user satisfaction and trust. From the literature review, we identify four characteristics which are expected to influence on user satisfaction: technical, information, customer-oriented, and work-performing characteristics. In addition, we develop research model that the four characteristics are expected to affect user satisfaction and trust via users' perceived values. The results of the research are as follows. The technical, customer-oriented, and work-performing characteristics significantly affects perceived values, which significantly affected user satisfaction and trust. Perceived value is partially mediated by user satisfaction in affecting user trust. The characteristics of local government web-sites affecting perceived values differed partially by the purpose of visitor. As for the personal goal, the technical, customer-oriented, and work-performing characteristics significantly affect perceived values, with the technical and customer-oriented characteristics having more significant effects. As for the business goal, the technical, information, work-performing characteristics significantly affected perceived values, with information characteristics having more significant effects.

Interoperability tests are required to determine whether network-based defense systems successfully share and exchange certain services, information, and data. We must examine various aspects of interoperability. The DITA (Defense Information Technical stAndard) is the basis for interoperability. However, DITA is being applied to the defense system in a state that the standard test methods and procedures are not established. And there is no test method and procedure of the DITA well applicable to military weapons systems or information systems. Therefore, in this paper, we propose a framework that includes procedures, methodologies, so as to test whether a standard is applied to the DITA in terms of Standard Conformance Test.

In this paper, we discuss CITIS(Contractor Integrated Technical Information Service) as the information infrastructure of CALS. CITIS is a contractor-developed and maintained service to provide electronic access and/or delivery of Government-procured contractually required information. As the concept of CALS is expanded government acquisition process into industry business, the CITIS is also expanded military CITIS into commercial CITIS. First, we describe CITIS services and functions defined by MIL-STD-974, and then specify the difference of military CITIS and commercial CITIS. The problem of current CITIS for inter-operable business process is indicated, and legal issues for sharing of CITIS data are also discussed.

CALS, being widely adopted by industry, is a strategy to share integrated digital product data through a set of standards to achieve effieciencies and competition in business. For CALS implemetation, creating a shared information system is necessary and CITIS is proposed for that. CITIS shall provide on-line access and automated exchange of all the technical information between contractor and service provider, and the function of CITIS is difined in MIL-STD-974. In this paper, regarding CITIS as a infrastructure of information for CALS, we proposed CITIS server system which comprise global data sharing software, global data management system, workflow manager, and configuration management maneger.

For the implementation of CE(Concurrent Engineering), the TDMS(Technical Document Management System) which integrates design and manufacuring information, is required. In this paper a drawing information management system, one of the essential modules for the TDMS has been developed. The system is operated in SUN SPARC II workstations. A CAD software called CIMCAD-2D is used for the storage and management of drawings. Relational DBMS ORACLE is used for the development of information data bases concerned with drawings. As an integration tool, the multi-media software called LINKAGE is used. Various functions for drawings and concerned information have been developed with the internal language CIMSHELL and SQL $^*PLUS$.

평생직장이 사라지면서 중년층은 재취업을 희망하고, 매년 실업률이 높아지면서 취업 포털 사이트를 이용하는 이용자들이 증가하고 있다. 이러한 이용자들에게 채용공고 정보를 제공해 주기위해서 보편적으로 Python 언어를 이용하여 데이터를 처리하고 수집한다. 하지만, Python은 다중 프로세스 기반을 갖춘 PC가 보급됨에도 불구하고 단일 프로세스로 처리하는 한계를 보이며, 나머지 프로세스에서는 데이터 처리를 하지 못하는 한계가 있다. 이러한 문제를 해결하기 위해 개선된 Python에서는 다중 프로세스로 처리 가능함에 따라 이를 이용한 채용 공고 수집기를 개발을 제안한다. 제안한 다중 프로세스를 사용한 수집기는 단일 프로세스보다 처리성능이 최대 3.42배 향상되었음을 확인하였다. 따라서, 다중 프로세스를 이용하여 채용 공고를 수집한다면 기존보다 더 빠른 데이터 처리와 데이터 수집 능력을 갖췄음을 확인하였다.

The amount of Meta-data to be managed increases with development of information technology. However, when trying to integrate and share product information of heterogeneous systems within or between companies, sharing of information is impossible if product information classification systems are different. Due to the situation mentioned above, engineers judge the product information classification system and maps corresponding Meta-data for document-based sharing. Judging exponentially increasing amount of data by engineers and sharing product information using documents create great amount of time delay and errors in data handling. Therefore, construction of a system for integrated management and interoperability between product information based on semantic information similar to engineer's judgment is required. This paper proposes a methodology and necessity of a system for interoperability of product information based on semantic web, and also designs a system to integrate heterogeneous systems with different product information using rule based reasoning. This paper also suggests a system base for interoperability and integration of product information between heterogeneous systems by integrating the product information classification system semantically.
