Construction CALS has been introduced with an aim to improve the effectiveness of construction management in the public sector. The objective of this paper is to provide an approach to implementing an integrated construction management environment. The environment described in this paper provides a methods for the owner and the contractor as well as designers and engineers to interact in a sing control scheme. This interaction represents the collaboration between the contractual parties for sharing construction information. XML technology has been applied as a basic technology for delivering data in the system. The XML-based forms are loaded on the system, whose data are stored in the central database right after review and approval. In future the integrated construction management environment can be further developed to the extend that the contractor's information system is directly interface with the owner's.

This study proposes schemes of GIS-based system development for integrated information management in water environment linked with Korean Reach File (KRF). For this purpose, precedent studies and systems of the U.S. were investigated and analyzed to induce optimal methodology for Korean circumstances. Thereafter, data linkage methods of KRF and Water Environment Information System (WEIS), system configuration plans, application development plans, and KRF improvement and maintenance plans were considered. For data linkage and system configuration, three methods were suggested: an overlay operation-based data linkage method, entering spatial addresses into the existing DB, and creating link information between KRF and the existing DB. The first method was predicted to be the most effective for system implementation, the second method is advantageous for search tasks, and the third method is advantageous for system security and maintenance. Various types of applications should be developed in the consideration of the types of the users and their usages. Moreover, there is a need for further research on regular renewal of KRF, standard development, expansion of construction areas, etc. Based on the present results, research on actual system design and development also should be conducted for supporting Total Maximum Daily Loads (TMDLs).

According to the fast-paced environment of information technology and improving customer services, the design activities of logistics systems improve customer centric services and delivery performance implementing e-logistics system. The fundamental design issues that arise in the delivery system planning are optimizing the system with minimum cost and maximum throughput and service level. This study is concerned with the integrated model development of delivery system with customer responsive service level for DCM, Demand Chain Management. We used a two-step approach for this study. First, we formulated the supply. center facility planning using stochastic set-covering problem and assigned the customers to the supply center using clustering algorithm. Second, we developed vehicle delivery planning for a supply center based on GIS, GIS-VRP. Also we developed a GUI-type computer program for proposed method for supply center problem using GIS and Geo-DataBase of Busan area. The computational results showed that the proposed method was very effective on a set of test problems.

Performance management of computer networks is intended to improve a given network performance in order for more efficient information exchange between subsystems of an integrated large-scale system. Improtance of performance management is growing as many function of the large- scale system depend on the quality of communication services provided by the network. The role of performance management is to manipulate the adjustable protocol parameters on line so that the network can adapt itself to a dynamic environment. This can be divided into two subtasks : performance evaluation to find how changes in protocol parameters affect the network performance and decision making to detemine the magnitude and direction of parameter adjustment. This paper is the second part of the two papers focusing on conceptual design, development, and evaluation of performance management for token bus networks. This paper specifically deals with the task of decision making which utilizes the principles of stochastic optimization and learning automata. The developed algorithm can adjuxt four timer settings of a token bus protocol based on the result of performance evaluation. The overall performance management has been evaluated for its efficacy on a network testbed.

In this paper, we consider an integrated inventory system where a single supplier purchases and processes raw materials in order to deliver finished goods to a single buyer for effective implementation of Just-In-Time purchasing. An integrated JIT lot-splitting model of facilitating multiple shipments in small lots is developed in a JIT purchasing environment. Also, an iterative solution procedure is developed to find the order quantity for the finished goods and raw materials, and the number of shipments between buyer and supplier. We show by example that the integrated policy adopted by both buyer and supplier in a cooperative manner can provide them a greater economic benefit than seeking the local optimal inventory policy independently.

As many Korean libraries has begun to be automated and become a part of the worldwide, open library system, they need a new management. Therefore, the purpose of this paper is to explore the library management in automated libraries and to establish a theory of the library management in information society, The automated libraries could be well explained by the systems theory and the environment of the libraries could be well explained by the contingency theory, The following hypothesis were set to direct this research. 1. As the libraries are automated and become a part of one big, worldwide library system, the libraries interact closely with the environment so that the library and the environment become one. 2. As the libraries are automated and become a part of one big, worldwide library system, the librarians need to work in the environment for the library networks, standardization of cataloging, or government information policy making. 3. As the libraries are automated and become a part of one big, worldwide library system, the librarians only manage the library, The various other library staffs take over the traditional library services directly related to books. The data were gathered from the research done previously, Also the date were collected from the American and Japanese libraries. The findings were as follows: The environment of the library integrated all types of the library services such as school library, university library, etc. And it also integrated all the services of the media centers and the press centers, etc. to library services. And the new library services began in the environment. Librarians worked for these new services. In the library, the librarians distingushed the library system from the environment by planning : mission, goal, objectives, policy, procedures and rules. Library organization became temporary such as forming task forces or matrix or free form. The environment controlled the library. Staffs were controlled by plans or computers. And the professional librarians were controlled by their ability to solve problems raised outside the libraries. Library leaders brought in the technology to the library from its environment. The librarians led the formal and informal organizations so that the staffs cooperated well in their work. And librarians tought the library procedures to the partime workers or the temporary staffs. Participative management and management by objectives were the means of motivating staffs. Budget was based on the ever changing environment. The zero based budget method was applied. Therfore, in the information society, the professional librarians become the able managers in the library and global librarians in the environment.

In order to adapt today's short product life cycle and rapid technology changes., integrated systems should be extended to support PDM (Product Data Management) or CE(Concurrent Engineering). A PDM/CE environment has been developed and a prototype is Presented in this paper. Features of the PDM/CE environment are 1) integrated product information model (IPIM) includes both data model and integrity constraints, 2) database systems are organized hierarchically so that working data C8Mot be referenced by other application systems until they are released into the global database, and 3) integrity constraints written in EXPRESS are validated both in the local databases and the global database. By keeping the integrity of the product data, undesirable propagation of illegal data to other application system can be prevented. For efficient validation, the constraints are distributed into the local and the global schemata. Separate triggering mechanisms are devised using the dependency of constraints to three different data operations, i.e., insertion, deletion, and update.

Each equipment has a durable life. The state of the equipment may change or fail until it is introduced, operated and disposed of. It is difficult for each organization to have a significant amount of these equipment and to understand each issue. Therefore, systematic life cycle management of equipment is more necessary than just for inventory purposes. In this paper, we design and implement an integrated management system for information assets. If it is an environment that can use the Internet based on the web, it can easily and easily access computerized information resource data through PCs, tablets, and smartphones. In addition, an integrated management system was established to limit the functions of higher and lower institutions through centralized management and user-level empowerment methods and to understand the overall status of resources.

GCM(Green Chain Management) is being spread by that companies which apply with eco-friendly concept in entire SCM(Supply Chain Management) perspective is being increased for resolving some recent environmental problems. There are reasons that numerous companies focus on GCM. At first various governments began to directly manage components and material contents about various noxious substances. Second, environment problem management in the entire logistics process from procurement of product materials to distribution of product became to be important according to introduction of certification system that evaluate the environmental impact throughout life-cycle of products. Purposes of this paper are 1) to analyze the GCM process whose important is more increasing in the recent logistics environment change, 2) to comprehend places and sources that generate environmental elements like energy consumption and greenhouse gas emissions in elements of logistics function, and 3) to construct integrated GCM system for observing activity of logistics function throughout life-cycle of products.
