In this paper, we present the design of a system on a chip(SoC) based on Powerline Communication for Power-IT. The SoC deals with power information obtained from analog to digital converter and transmits this data via powerline. We integrate main processor, ADC and PLC function into a chip. Also a FPGA-based emulation system is introduced to evaluate a proposed SoC architecture.

Shipbuilding is basically labor-intensive industry. It creates a number of job opportunities, but it is classified as a high risk industry like the construction industry. Shipyards show similarities in many aspects compared with the construction sites. There are many stakeholders of the HSE managements in the shipbuilding industry, such as ship owner, primary contractor and multi-layered subcontractors. The ship owners who are almost foreigners are treating strictly about safety and health. Therefore, it is necessary to development an appropriate HSE management systems and for the management systems it is desirable to information technology (IT) to accommodate these complex and complicated problems and situations. It was developed the ISP (Information Strategic Planning) as a HSE management system for the shipbuilding industry. It consisted of the environment analysis, the As-Is analysis and the To-Be design. In this study, the ISP is introduced and further it is suggested that it should be connected to system of HR(Human resource), PM(Plant maintenance) and KM(Knowledge Management) to make the HSE management system efficient.

A variety of enterprises have Implemented ERP system on the promises of feasible strategic benefits. The objectives of this study are (1) to classily and analyze the motives and critical success factors o the enterprises'ERP system adoptions, and (2) to measure their impacts on the business performance. The data for this research were collected from 43 cases in Korea that have operated ERP system for more than 6 months after the implementation. This study results reveals that the Information strategic planning and business strategy establishment prior to ERP adoption and the demands of field people activate as critical triggers In the larger firms Among the six critical success factors, training was statistically significant for all of four performance measures control, cost reduction, quality and service, and work efficiency. And other findings are furnished. Also the larger company group In the sales volume has shown the higher performance except work efficiency.

Strategic alliance between corporations is essential to build a CALS system. Specially, companies cooperate one another to accomplish the shared environment in the system. During the construction of the CALS system, we can apply the concepts of ILS and SCM to develop the breadth and depth of shared environment between firms. In order to build such intended environment in the CALS system, we propose five dimensions with 30 variables to be considered. These dimensions are Information Sharing, Task Sharing, System Sharing, Parts and Facilities Sharing, and Institution Sharing. Structured interviews were peformed to measure the degree of shared environment designed in 7 CALS pilot systems in Korea. The results show that the level of the shared environment in the context of vertical relationships between firms in the CALS systems is fairly high. In contrast, the level of the sharing between competing companies in horizontal relationships is relatively low in most of the pilot systems.

In the past, executive managers made a decision based on personal experience and knowledge due to lack of the appropriate and timely information. With the development of information systems and technologies, efficiency and productivity of business operation has been enhanced. In this study, we propose a system design and architecture blue-print related to strategic decision making support system. The proposed system consists of 3 key parts; individual business feasibility test, business portfolio feasibility test, business portfolio management. The three key parts are comprised of 11 components to generate information and knowledge based on various data input from inside and outside of firm. This system is expected to provide objective and reliable output to users. In addition, the proposed strategic decision support system would help respond to a rapidly changing business environment.

This paper presents a dynamic development of an ontology-based statistical information system supporting the collection, storage, processing, analysis, and the presentation of statistical knowledge at the national scale. To accomplish this, we propose a data mining technique to dynamically collect data relating to citizens from publicly available data sources; the collected data will then be structured, classified, categorized, and integrated into an ontology. Moreover, an intelligent platform is proposed in order to generate quantitative and qualitative statistical information based on the knowledge stored in the ontology. The main aims of our proposed system are to digitize administrative tasks and to provide reliable statistical information to governmental, economic, and social actors. The authorities will use the ontology-based statistical information system for strategic decision-making as it easily collects, produces, analyzes, and provides both quantitative and qualitative knowledge that will help to improve the administration and management of national political, social, and economic life.

We study Interpreted Systems, ATL, and ATEL to capture the notion of time, knowledge, and strategy which are important in the analysis of multi-agent systems and propose strategic constraints based on subgame perfect Nash equilibrium of game theory as one of the solutions for the issues of ATEL which an agent can access the current state of the whole system when making up his strategy even when he should be uncertain about the state, and no explicit representation of actions in ATEL models makes some natural situations harder to model. Also, we present strategic constraints-based Interpreted Systems for model checking of multi-agent systems.

The application of computers and information technologies progressed with remarkable pace has paved the way for technological innovation toward the efficient integration of various functions in a manufacturing system. Actually it is observed that the greater part of manufacturing companies already initiated significant efforts to integrate information systems and attained the level of integration to some extent. The purpose of this paper is to clarify the strategic direction that manufacturing firms are pursuing through integrating information systems. Using the extensive data gathered from Japanese manufacturers, it is attempted to find the differences in competitive priorities and action programmes between the companies with high and low-level system integration. Our empirical data reveals that the manufacturers with highly integrated system are focusing their competitive capabilities on the rapid design change and new product introduction, and accordingly they place a greater emphasis on the action programmes related to design, process and quality improvement. As a conclusion, highly integrated firms tend to pursue new product development strategy more intensively, thereby they want to be a preemptor in the new market through exploiting technological advantages of integrated manufacturing system.
