The "leading farms" or "superior management farms" were relatively capable to overcome various limitations in rapidly changing agricultural environment and economic conditions, and quick to adopt agricultural management innovations and accomplish more compared to the other farms in shorter durations. The farmers from these "leading farms" were innovative and dynamic, and endowed with potentials to be the core leaders in rural society. Their adaptability created a difference and worthy of emulations. The purpose of this research was to propose a policy to develop, promote and sustain these leading farms. There were some problems in communication structures and in implementing agricultural policies for upbringing leading farmers. In coordination with the Ministry of Agriculture and Forestry(MAF) and Rural Development Administration (RDA), this article attempted to come up with workable strategies to solve these problems affecting the leading farms.

This paper covers a plan to build supply chain cooperation systems among stream of the textile industry to strengthen international competitiveness. To obtain the study objective, it has been reviewed the theoretical rationale relating to organizational cooperation model and discussion and performed the case study that analyzed stream group and participated firms to the textile stream policy project. The analyzed stream cooperative types that measured configuration of cooperative degree and productive type are new market creation, technology improvement, relation maintenance, and relation cease. Two types - new market creation and technology improvement - have significant effect of the textile stream cooperation. Key successful factors of these two effective types are the external intervention of specialized consulting organization and build internal coordination and integrated mechanism to the cooperative stream group and participated firms.

This study explores how strategic alliance activities are evolving and the factors that impact on the formation and development of airline alliances. Findings show the initiation of regional and more liberalized bilateral, or open skies, agreements have removed some of the impediments to structural changes in international aviation. Airlines in more liberal markets enter into greater numbers and more integrative forms of alliances. Also, airlines, on average, achieve better results of operation if the market is more liberal. Essentially, there is a positive relationship between the developments of alliances and the liberalization of air transport markets. It has been questioned that the US bilateral open skies agreements provide its carriers more access to the global market and countries that do not enter into such agreements with the US risk a loss of traffic. Consequently, open skies agreements may enable carriers who have the freedom to exercise market power to be dominant in the markets. This suggests that regulatory coordination and liberalization of international aviation reinforce each other and should therefore be pursued simultaneously.

Point Coordination Function (PCF) of the IEEE 802.11 protocol providing a centrally-controlled polling-based multiple access to a wireless channel is very efficient in high load conditions. However, its performance degrades with increasing the number of terminals and decreasing the load, because of wastes related to unsuccessful polling attempts. To solve the problem, we propose and study analytically the generic dynamic polling policy using backoff concept. For this aim, we develop Markov models describing the network queues changes, what allows us to estimate such performance measures as the average MAC service time and the average MAC sojourn time, to show the dynamic polling efficiency and to tune optimally the backoff rule.

This paper surveyed the development and future of electronic journals. The growing and impact of electronic publishing, developments and access of electronic journals, and the future of electronic journals were examined in detail, and remaining problems were analyzed. The findings of the study can be summarized as follows : 1. The future of electronic journals is not an issue of technology it is an issue of economics and social policy. And, the cost of delivering an electronic version to end-users were more expensive. 2. More sophisticated markup software and display software system are needed for fully structured text versions of articles. 3. Coordination of effort is essential in order that we maximize the end-users access requirements against resonable protection for the intellecture effort of the scholarly writer. 4. The success of an electronic journals will depend on the improved communication and cooperation between libraries, users, author, publishers, and information technology specialists. The advent of electronic information delivery has brought with it these issues to be solved. And development in the delivery of scholarly information by electronic means will accelerate.

This study explored the patterns of activities and interactions among participants in the adoption process of a new system innovation, ADSL, in Korea, using an integrative framework of innovation system and strategic decision-making process for uncertainty reduction. An in-depth case analysis was undertaken to identify the adoption process of ADSL innovation, as a case in point, in conjunction with activities and interactions among related parties such as government, service providers, equipment suppliers, and content providers. The results of case analysis revealed that as the level of uncertainty in the adoption of ADSL innovation decreases, the focus of decision-making activities moves from scoping, to searching, to evaluating and to committing. Also this study found that at the early stage of ADSL adoption with higher level of uncertainty, government plays a pivotal role in coordination of related parties to participate in the innovation process, while service providers replaced this role at later stage of innovation with lower level of uncertainty. This study discussed theoretical and policy implications for the adoption of new system innovations with varying degrees of uncertainty.

농촌개발에 관한 정책영역이 농촌공간 단위의 농업정책과 비농업정책을 포괄하는 방향으로 진행됨에 따라 관련된 농촌개발주체는 분산, 다기화되어 있다. 필리핀의 경우 농촌개발과 관련된 중앙정부의 관련부처는 상대적으로 세분화되어 있으며, NGO 등의 관련기구도 많은 편이다. 또한 필리핀의 지방행정계층의 수도 다른 나라에 비하여 상대적으로 많다. 이는 중앙정부 부처간, 중앙부처와 NGO 및 중앙정부와 지방정부간의 조정을 어렵게 하는 요인으로 작용한다. 한편, 지방정부 레벨에 있어서는 농촌개발과 관련된 관련주체간의 조정시스템에 관하여 지방정부법(1991)에 상세한 규정을 두고 있으나, 실제적인 작동의 면에서 한계를 가지고 있다. 특히, 필리핀의 농촌개발과 관련된 지방단위의 관련주체의 역량은 충분히 함양되지 못하고 있는 상황에서 주민과 NGO의 농촌개발에 대한 참여(민주성)를 매우 중시하고 있다. 필리핀 농촌의 발전을 위해서는 관련 주체들의 분산도를 감소시키고, 주체간의 통합성의 증진을 위한 노력이 필요하며, 관련 개별주체의 역량강화와 효율성에 입각한 조정체계의 정립과 전략이 절실히 요구되고 있다.

The coordinated control of the traffic signals of adjacent intersections can reduce delays, relative number of stops and congestions in the coordinated traffic area. The road capacity can be increased to a certain extend because the stopping and starting of vehicles facing red traffic lights can be avoided in many instances due to the progression established along an artery. However, if traffic centers or leaves the main flow in irregular volumes on the intermediate road section, a coordination of traffic signals is unnecessary and may even be harmful. Therefore, a computer simulation model to simulate and predict the effectiveness of a synchronized traffic signal system in the CBD of Seoul was developed and alternative policy variables, such as cycle time, offsets, phase splits, to be fed into the simulation model had to be generated. This is a report of (1) the development of a heuristic algorithm for the determination of phase splits when there are amber periods specifically reserved for left turns and (2) the computerization of time-space diagramming.

This paper comes from an observation that overemphasis on capacity utilization meausre, which is usual under capacity shortage, can seriously hurt the firm's profit and potential process improvement. We suggest a model that can be used in designing a coordination scheme for decentralized marketing and manufacturing activities. Using a price and time-sensitive demand and capacitated lotsizing model, we derive an effective communication medium betwen marketing and manufacturing. This Balance Indicator of process capacity and flexibility also implies that the increase in capacity availability and setup time reduction should be balanced by its market requirements. This is particularly important when a firm tries to improve its process capability by kaizen. Further, the model can be used to show the comparative performances of scheduling policies under capacity imbalnce. We show the shortening the scheduling cycle can improve the firm profit without changing the simple scheduling rule.

This study aims to provide information about the priority setting and budget coordination of government R&D spendings in Korea. Based on the result of "survey, analysis and evaluation of national R&D programs" in FY 1999, this paper reviews the government R&D expenditures by concerned variables such as program objectives, sector of performance, character of work and technology fields. This paper also carries out an analysis on the government R&D supports as ways for the promotions of high technology-based start-ups and SMEs and regional innovation activities. It is found that relatively high investment is made in the industrial technology areas and development research, and there are some redundancies of R&D programs among ministries and agencies in terms of technology fields, program objectives and character of work. Policy implications and future research directions are suggested.
