Recently, we have witnessed a host of emerging tools in the management support systems (MSS) area including the data warehouse/multidimensinal databases (MDDB), data mining, on-line analytical processing (OLAP), intelligent agents, World Wide Web(WWW) technologies, the Internet, and corporate intranets. These tools are reshaping MSS developments in organizations. This article reviews a set of emerging data management technologies in the knowledge discovery in databases(KDD) process and analyzes their implications for decision support. Furthermore, today's MSS are equipped with a plethora of AI techniques (artifical neural networks, and genetic algorithms, etc) fuzzy sets, modeling by example , geographical information system(GIS), logic modeling, and visual interactive modeling (VIM) , All these developments suggest that we are shifting the corporate decision making paradigm form information-driven decision making in the1980s to knowledge-driven decision making in the 1990s.

In this paper, an effort has been made to design and develop an optimized programming model for Real-time Ship Management System. Replacing the conventional interrupt-driven programming model, an embedded real-time operating system (RTOS) has been implemented on the system, allowing processes to run virtually simultaneous and multitasking. Data management algorithms are designed and developed in the RTOS to facilitate data distribution amongst tasks and optimize the CPU processing time through intelligent resource utilization. Finally, data lost in the system has been minimized via the improvement of data processing rate under the optimized programming model.

Recently, the lawn has plenty of uses in parks, school grounds, golf courses, gardens, etc. So the lawn market is expected to grow. But the cost of running for lawn management has increased, and there are also environmental issues by using pesticide. In this study, we propose Smart Lawn-management System based on Image Processing which increase the efficiency of management and reduce expenses of operation.

PLM(Product Lifecycle Management) is an information management system that can integrate data, processes, business systems and human resources throughout the enterprise. BOM(Bills Of Material) is key data for designing, purchasing materials, manufacturing planning and management, which is basic for product development throughout the product life cycle. In this paper, we propose the efficient system to increase the data loading speed and the processing speed when using such large BOM data. We present the performance and usability of IMDG (In Memory Data Grid) for data processing when loading large amounts of data. In the UI, using the pure web grid of JavaScript instead of the existing data loading method can be improve performance of data managing.

Development of information and communication technologies has given a lot of changes in the business processing methods including the school and class managements. However, many business processing systems are still based on desktop computer. In particular, most of the class management system only supports desktop computers; hence school teachers have difficulty in using their class managements systems on mobile environment. In this paper, we proposed and developed a mobile classroom management system for teachers, which will easily handle information such as personal records of students, student counseling records, student life record and so on. The implementation of the application of mobile-based class management can be managed by many school elements including student register information, student evaluation records and transcripts, counseling report, and so on.

Recently, research activities for combining portable computer technology and wireless communication technology are in progress to realize mobile computing environment that designed to support mobile hosts in the existing network environments. For PCN environments, the location management strategies are particularly emphasized among various strategies necessary for the mobile computing environment. Location management strategy for PCN environment, which is mostly based on the IS-41 standards brings an issue that additional network traffics are generated to deliver updata messages to home location server whenever a mobile host changes its location server. In this paper, we propose an innovative updata strategy and a search strategy that resolves the problem shown in the IS-41 scheme for HLR/VLR structure of CDMA environments. Also, this paper presents the performance comparison of proposed scheme and scheme used in IS-41 obtained from a simulation. The simulation was conducted based on the number of messages, the rate of database accesses, and the number of hops visited when the location management scheme is executed.

웹기반의 LCMS(Learning Content Management System)는 단지 학습 콘텐츠를 LMS(Learning Management System)에 제공하기 위하여 검증이 되지 않은 다양한 학습 콘텐츠를 탑재하는 시스템으로 구성되어 있어 학습자의 요구와 수준에 맞는 콘텐츠의 제공이 제대로 이뤄지지 않고 있다. 본 논문에서는 LMS와 LCMS를 연계한 학습이력정보와 학습 콘텐츠의 정보 관리를 함으로써 학습콘텐츠의 질적 향상과 학습자가 선호하는 콘텐츠의 정보를 통계적으로 보여주고 또 분석이 가능하게 함으로써, 학습자에게 보다 향상된 콘텐츠를 제공해 주기위한 학습콘텐츠관리시스템인 LCIMS(Learning Content Information Management System)를 설계하고 구현한다. 제시된 LCIMS는 기존의 LCMS에 학습 콘텐츠를 패키지 또는 SCO 단위로 등록하여 콘텐츠 저장소 (메타데이터 및 콘텐츠 파일)에서 체계적으로 저장 및 관리하는 역할을 추가를 하고 학습자별로 LCIMS의 학습콘텐츠 정보를 수준별, 과정별로 평가, 검색하여 LMS를 통해 학습 할 수 있도록 하는 검색 및 강좌 구성에 활용하며 학습자의 학습정보관리와 학습콘텐츠 정보의 관리를 체계적으로 할 수 있다.

This paper introduces a design scheme of intelligent gas valve management and service system based on Internet. This scheme adds sensor and general packet radio service (GPRS) modules to the traditional gas valve and establishes communication connection between gas valve and the server through wireless packet communication technology, which makes the traditional gas valve have the networking ability. Compared with the traditional gas valve management and service business, the method proposed in this paper is more convenient and efficient.

For running various construction processing information and technological information, it is supplied by Construction CALS/EC systems properly during whole facilities life cycle. So it is urgently necessary to change Regional Construction 8t Management Office (RCMO) equipment construction administration business to electron processing system (CALS/EC). From construction work plan to completion, a present storage documents system is unsystematic. Therefore, it needs management system to store documents and to read in turn documents properly. This research suggest that it is to connect with various information systems and Construction CALS/EC for RCMO which is running public construction field. So it can be driven systematic and effective administration system about public construction business by Web-based present construction situation information system.
