The purpose of this paper is to analyse the industrial structure and competitiveness of five large cities in Korea. say Pusan, Taegu, Inchon, Kwangju, and Taejon. These cities are performing more important roles in this borderless society. Industrial competitiveness may not fully represent the competitiveness of a city, rather is one of the major constituents of urban competitiveness. The selected indices representing industrial competitiveness of a city include regional industrial share, location quotient, growth potential. productivity. profitability. The analyses reveal that all the five large cities are required the tasks for industrial restructuring in facing with the rapid deindustrialization trend. Inchon shows relatively competitive position in a number of industries, while the others are revealed weak in most categories of industries.

This study aims to analyze an evolutionary path and the dynamics of the Seoul Digital Industrial Complex in Korea based on the analysis of cluster life cycles. From the mid 1960s to the late 1990s, the life cycles and their characteristics of the Seoul Digital Industrial Complex (Guro Industrial Park) are examined as emergence-growth-sustainment-decline focused on the number of firms and employees. After the late 1990s, the number of firms and employees increases rapidly and the active actors of the growth and restructuring are transformed to the technology-intensive SMEs and knowledge-based service firms. Knowledge industry centers (apartment-type factories) help evolve into the life cycle of transformation as knowledge-based clusters after the mid 2000s.

Due to environmental change in market, delivery satisfaction to customers and reduction of lead time are critical in the make-to-order manufacturing system. A case of production scheduling process restructuring is studied for one company which employed ERP system. Based on the standard module ERP package provided, they modified and added several functions for their specific processes, and implemented it in production scheduling. The ratio of delivery satisfaction has been improved from 51.1% to 60.8%, and manufacturing lead time has been reduced from 43 days to 30 days in average during 10 months. Moreover, they achieved several side effects such as real time production scheduling and workload analysis, information sharing over all departments, and improving flexibility in receiving orders.

The study intends to find out contents and impacts of rural development projects implemented by government in Ucheon myon-center village (Hoingseong-county) between 1989-1995. The projects in concern are Rural Industrial Estate Project(1989-90) and Rural Collective Village Project(1992-93), The restructuring of village plan introduced new construction and renewal of buildings that are required for a myon-center in general has to be. The study reveals some morphological patterns the village has and needs to be adjusted. As a conclusion, it proposes a conception of self-containment for a myon-center development. It is necessary that a project plan strategy should be based upon harmonious exploitation between old and new, flexible planning, and sense of technological alternatives.

South Korea's solar energy industry has been made vertical integration and specialization as part of the restructuring in the downturn of the world economy and the oversupply situation of raw materials. This study is to understand the characteristics of the solar energy industry, using data to systematic approach. In this study, it was defined the major business of firms as 22 business types and classified into 5 enterprise groups as technology and business strategy. After that, It was deduced features of Enterprise group by the statistical analysis and looked to draw a map of the industrial structure by social network analysis using the information on companies' demand and supply.

The main purpose of this study is to highlight the importance and validity of introduction of stress-concerned aptitude items for the safety critical workers, corresponding to the radical environmental change in railway industry. To attain this purpose, the author performed a brief literature survey, and scrutinized the western practice in detail. Then, the necessity of introduction of stress-related aptitude items was suggested, based on the statistics resulted from a survey which has been once performed for experts and drivers. The final conclusion is that the present selection system through which the safety critical workers are being staffed, without any rigorous screening mechanisms cannot but have some limitations. So, an overall restructuring for aptitude management system needs to be done in order for us to advance to the position of upper-class railway country.

Not only has there been movement along the sectoral continuum, Johnston argues, but changes in the spatial balance of policing are also visible. More concretely, he suggests that British policing has been undergoing a century-long process that has gathered pace since the 1960s. Three factors have been central to this process. First, legislative centralization brought about by the Police Act 1964 - which established the tripartite structure for police governance and amalgamated forces - and the Local Government Act 1972 which reorganized local government. Secondly, the political and industrial unrest of the 1970s and early 1980s led to the establishment of new levels of national police co-operation and, in the words of one author, to the establishment of a 'de facto national police force'. Thirdly, increasing European influence has further internationalized police co-operation and organization. Johnston concludes that the spatial restructuring that appears to be taking place in British policing is indicative of a broader process of fragmentation of social structures and systems for maintaining order.

The electric power industry has played an important role in dramatic economic development in Korea and the electricity has constituted a critical factor sustaining the well-being of the Korean people. This study uses input-output analysis to investigate the role of four electric power sectors (hydroelectric, fossil-fuels, nuclear and non-utility) in the Korean national economy for the period 1985~1998, focusing on four topics: the impacts of electricity supply investments, the electricity supply shortage effects, and the impacts of the rise in electricity rates, and the inter-industry linkage effect. The overall results reveal that non-utility electric sector is superior in terms of the national economy-wide effects to other three sectors throughout the period. Finally, potential uses of the results are illustrated from the perspective of policy instruments and some policy implications are discussed.

The goal of this study is to investigate computational convergence of optimal solutions, with respect to optimality criteria (OC) method and methods of moving asymptotes (MMA) as optimization model for non-linear programming of material topology optimization using an acceleration method that makes design variables rapidly move toward almost 0 and 1 values. 99 line topology optimization MATLAB code uses loop vectorization and memory pre-allocation as properly exploiting the strengths of MATLAB and moves portions of code out of the optimization loop so that they are only executed once as restructuring the program. Numerical examples of a simple beam under a lateral load and a given material density limitation provide merits and demerits of the present OC and MMA for 99 line topology optimization code of continuous material topology optimization design.

EDI(Electronic Data Interchange) allows the exchange of business information and computer-processable data in a standard, structured format electronically between organizational entities. EDI handles the restructuring of a business document into the standard format so that it can be transmitted from one computer to another. This paper identifies features and technologies of web browsed electronic document exchange system as follows 1) the fundamental technologies that consists of the EDI technologies, the Internet/Web technologies, the security/authentication techniques, and the XML implementation technologies. 2) the functions that consists of the document standards, transfer technology of the document, encryption and authentication 3) the implemented Web-EDI systems that consists of document generation module, encryption and authentication module, transfer module, acknowledgement module, administration module. In this paper, the Web-based EDI system implemented from the researched technologies will be installed on the EDI servers owned by corporate customers and enable the exchange of documents between each installed companies.
