This paper suggests a contingent perspective for analyzing information systems issues of the Korean firms. The contingent perspective includes such corporate characteristics as industry, organizational size, strategy, and value-added application function. This research surveyed 119 corporations in manufacturing, banking, distribution, and construction industries. Among those samples 104 data of corporate IS managers turned out to be statistically valid. As a result, those issues are ranked as the most urgent and important IS issues: strategic IS planning, system integration, application of database, process standardization, and network planning and implementation. Furthermore, factor analysis says that thirty issues to be surveyed are to be grouped into seven factors such as IS planning, user/education, database, applications of IT, system management, distributed computing technology, and network applications. It also found through Pearson correlation and ANOVA that organizational characteristics highly influences the IS issues the corporations face.

The design methodology of injection molding die has been changed from two-dimensional drafting to three-dimensional solid modeling, which is due to many advantages over the conventional methodology in terms of design modification and data associativity. In addition to the solid modeling capability, it is required for a mold designer to utilize a database management system that facilitates efficient mold design. In the paper presented is the implementation of a software program which automatically generates three-dimensional mold-bases including standard parts and slider parts, conforming to given geometric constraints. It is based on a commercial CAD system (Unigraphics NX) along with related API (application program interface) libraries. The research is expected to reduce design efforts and simplify construction of a complex three-dimensional mold-base model that is comprised of standard parts and slider parts, by use of the three-dimensional database and automatized geometric dimensioning.

The main objective of this research is to develop an experimental educational facility management information system that will be used for maintaining existing educational facilities in the elementary, junior high, and high schools. The development is based on the nationwide development plan of the education administration information system. The system developed is accomplished by use of Map-application Information System(MAPIS), an applied commercial software that combines Geographic Information System(GIS) with existing Information and Communication Technologies(ICT) such as Database system, Multimedia methodology, and Internet system. In order to figure out the features to be improved in the system developed, the research interviewed the educational facilities management in the Ministry of Education and P Local Education Authority. The authors suggest the functional improvement of the system based on the interview results.

집중 호우로 인한 침수, 산사태와 같은 자연 재해는 인명, 재산 피해 뿐만 아니라 교통혼잡 및 고립과 같은 피해를 주게 된다. 도로 공간에서 운전자들은 이러한 재해정보를 인지하지 못할 시 해당 위험지역으로 진입하게 되며 그 피해는 시간이 지날수록 확산된다. 본 논문에서는 이러한 위험지역에 대한 정보를 수집하기 위하여 스마트폰 애플리케이션과 전송받은 데이터를 관리하기 위한 C/S기반의 시스템을 개발하였다. 전송받은 데이터를 이용하여 위험지역을 분석하고 분석된 위험구간정보에 대한 공간데이터베이스를 지도 서버를 이용하여 스마트 폰 애플리케이션 상에서 표출 할 수 있어 보다 효율적인 정보 제공이 이루어 질 수 있을 것이라 생각된다.

This Paper makes an attempt to suggest a process of automatically generating application software based on the Entity-Relationship model 1. The designer develops an E-R model of an real-world system. 2. The designer inputs the entity and relationship types, and attributes shown in the E-R model, and also the basic operations of the application system to the software generator. 3. The application generator produces database schema and link information between application programs, and then automatically generates a stereo-type application system. In order for the automated application generator to build the application system in a systematic way, four basic program generation rules have been suggested. A set of computer programs have been developed in order to show the applicability of the automated software generation process suggested in this paper. By following each rule with the generator, the designer can build an application in an efficient manner compared with traditional (manual programming) approaches. It has been demonstrated from the case study that the idea of applying an automated generator in systems development based upon the E-R model is feasible.

This study is aimed at standardizing the process of spatial database construction and developing a software tool for process management. Knowhow of five GIS firms and provisions of NGI(National Geography Institute) was analyzed. In this study, the process of spatial database construction was standardized. The system from this study has the capability to manage the process of construction database using GIS and to deal with the metadata of unit map, generated from the process, systematically and continuously. The process was also shown by using either Gantt chart or PERT chart after developing an interface for "MS Project". A software "Visual Basic for Application" was used for this study.

As the use of vehicle route application and LBS(location based service) are fast grew, the importance of maintaining road network data is also increased. To maintain road data accuracy, we can collect road data by driving real roads with probe vehicle, or using digital image processing for the extraction of roads from aerial imagery. After compare the new road data to current database, we can update the road database, but that job is mostly time and money consuming or can be inaccurate. In this paper, an updating method of using GPS(global positioning system) enabled cell phone is proposed. By using GPS phone, we can update road database easily and sufficiently accurately.
