This study deals with the regulatory policy of government on the convergence of broadcasting and telecommunication by applying rent seeking theory to Internet Protocal TV (IPTV). Existing literature has mainly focused on the negative implications of rent seeking since Tullock [1967], Krueger [1974] and Buchanan [1980]. We have investigated the regulatory policy along with the progress of the convergence of broadcasting and telecommunication. Regulatory policy on broadcasting, despite its impartial intent. has created the entry barrier in the industry, resulting in high rents. Meanwhile, regulatory policy in telecommunication is more geared by the encouragement of more competitive environments, resulting in reasonably low rents in the market. Regulatory policy in the age of convergence needs to improve the efficacy of the industry and welfare, while maintaining the rent at a reasonably low level. This research has contributed to emphasizing the positive aspect of rent seeking in policy concerned with the convergence of broadcasting and telecommunication, notably IPTV.

Industrial business environments have rapidly changed and face severe competitive challenges. The effective inventory system enables to product and deliver the products quickly for meeting due date of customer's order in this environment. This study have developed a web-based inventory system using RFID for an injection molding industry. The system analysis inventory problem issues such as inventory planning, warehouse assignment and assist to develop production scheduling. In this study, web-based inventory system using Java language and RFID technology is proposed and implemented. As the result of implementation of the system, we expected that it manages to inventory planning continually and systematically.

Changing environments in agricultural business make it necessary to promote the cooperative farming system so as to scale up farming size, which may contribute to increasing competitive power. Therefore, rural and fishery development program was established in 1990 to encourage individual farmers to jointly form the agricultural company or farming cooperatives. However, while the number of agricultural corporations has rapidly increased through the governmental support, their business achievements become worsening mainly resulting from unplanned and careless management practices. This paper suggested following strategies for management process reengineering to improve the efficiency of agricultural corporations; challenging business initiatives to enlarge volume of sales amounts, maintaining the optimal level of participants and physical assets for cost savings, and proper use of information technology and consulting agencies.

최근 기업들은 글로벌 경쟁과 국내외 경영환경의 빠른 변화로 인해 과거와 같은 경영방식과 생산수단으로써는 경쟁에서 이겨나가기가 어려워지고 있다. 이와 함께 정보와 지식의 효과적인 활용을 통한 기업 경쟁력을 향상하려는 지식경영에 대한 관심이 높아지고 있다. 따라서 본 연구는 지식경영의 성공요인들을 계층분석과정(AHP)을 통해서 찾아내고 성공요인들 간의 상대적인 중요도를 파악하여 지식경영을 도입하려는 기업들에게 성공적인 도입을 위한 시사점을 제공하고자 한다.

The purpose of this study is to present the advanced plans to get the activation of the domestic furniture manufacture, considering the conditions of the furniture market and business environments before and after IMF Economic Crisis. These are necessary to get over some problems which result in reduction of demand, consumption, and investment under the recession. The furniture manufacture should take the occasion as a pertinent opportunity to strengthen the competitive edge and step up the exploration of the international markets. It is reasonable to conclude that the advanced plans should be designed, implemented, and expanded through the inducement of the government, manufacturers, and foreign investors.

Purpose: This study compares quality crisis and management at Hyundai Motor in the late 1990s and Toyota Motor in the late 2000s. We can expect to induce more meaningful policy implications in quality management from this in-depth comparative case study. Methods: This study compares two cases at Hyundai and Toyota Motor how to overcome quality crisis based on the OESP (Organization-Environments-Strategy- Performance) model. Results: Hyundai Motor shows centralized approach based on the asymmetric organizational culture and the entrepreneurial leadership but Toyota shows decentralized, systematic approach based on the steady state leadership and symmetric organizational culture. The CEO's leadership have proved to be one of the important factors at both companies. Conclusion: The effective quality management in global contexts has become more and more difficult for the 'complexity explosions' in automobile industry. As a consequence, the future competitive edge of world automobile industry will come from the effective quality management of products in global contexts.

The competitive advantage of technologies is required for survival of enterprises in the social environments which change rapidly. So the strategy of technology development becomes more and more important. For the establishment of strategy, the situational analysis and the forecasting analysis are executed and they include the technology assessment and the technology forecasting. This research is intended to find out the problems and the difficulties in the current Matrix Method, and to improve the method, finally to help the R&D departments of enterprises applying the method. The suggested matrix(TSM : Technology Shift Matrix) method is designed so that one can judge the current situation of technology and future trend, by moving the matrix which is placed to the upside of the basic matrix.

Arsenic is among the heavy metals commonly found in aqueous environments. Iron oxide is known as an efficient adsorbent for the arsenic. A new synthetic method was applied to provide iron oxide giving a large specific surface area. The mixing method affects the formation of iron oxide. Ultrasonic waves assisted the formation of very fine iron oxide in an organic phase. The synthesized iron oxide is amorphous type with a high surface area of more than $181.3m^2/g$. Sorption capacity of the synthesized adsorbent was relatively very high for arsenic and varied depending on the oxidation state of arsenic: a higher capacity was obtained with As(V). Lower solution pH provided a higher sorption capacity for As(V). The competitive effect of co-exist anions such as chloride, nitrate, and sulfate was minimal in sorption capacity of the iron oxide for arsenic.

The AEC (Architecture/Engineering/Construction) industry is facing a competitive world after it entered into the 21^st century. Due to improper planning and scheduling, the construction projects face severe delays in completion. Most of the present day construction organisations operate in multiple project environments where more than one projects are to be managed simultaneously. But the advantages of planning and scheduling as multiple projects have not been utilized by these organisations. Change in multi-project planning and scheduling is inevitable and often frequent, therefore the traditional planning and scheduling approaches are no more feasible in scheduling multiple construction projects. The traditional scheduling tools like CPM and PERT do not offer any help in scheduling in a resource-constrained environment. This necessitated a detailed study to model the environment realistically and to make the allocation of limited resources flexible and efficient. This paper delineates about the proactive model which will help the project managers for scheduling the multiple construction projects.

The dynamic nature of the A/E/C industry, rapidly changing global market environments, and lowest cost competitive bidding make it difficult to survive in global design markets. To understand the global design markets, a case study has been undertaken. The top 150 global design firms represented in the ENR (Engineering News Record) from 1995 to 2003 are classified into three groups for the case study. First group is the firms which advanced in rank from 1995. Second group is the firms which maintained its rank from 1994 until 2003. Third group is the firms which went down in rank from 1995 until 2003. However, finding key factors and changing business strategies of successful top design firms are the fundamental goals in this paper. After examinations of case studies, this paper concludes and suggests that professionalization, M&A strategies, patrons of the government, and academic support are needed to be successful in the global design & engineering industry.
