Intermediaries are presenting not only transactional information that orchestrates electronic transaction, but also market related information and knowledge useful for sellers' understanding of the market status. However, we do not have strong evidence that the market related information and knowledge is properly utilized by sellers and that it has an actual influence on sellers' performance. According to the research result, absorptive capacity and the pattern of information system utilization is statistically significant to sellers' performance mediated by operational efficiency and market knowledge creation. Especially, explorative utilization of information system and realized absorptive capacity has a stronger influence on sellers' performance mediated by market knowledge creation. With this research result, this study maintains that sellers are required to absorb and utilize market related information and knowledge more actively through explorative utilization of information system to achieve better performance in the e-marketplace. On the other hand, intermediaries are recommended to provide abundant and valuable market related information and knowledge for the sellers to build up better e-marketplaces.

This study was aimed at measuring the fishing capacity of Powered Anchovy Drag Net Fisheries (PADNF) in Korea using Peak-to-Peak(PTP) and Data Envelopment Analysis(DEA) methods recommended by FAO. In the analysis, both fishing capacities of total PADNF and individual PADNF vessels were measured with time series data and cross sectional data, respectively. In addition, the results of the DEA measurement were analyzed in order to determine reduction levels of fishing capacity. In case of total PADNF, the results by rn and DEA methods showed a similar rate of capacity utilization (79%), indicating the capacity was not utilized enough. In addition, the sensitivity analysis suggested that the number of vessels should be reduced by 20%, and the gross tonnage and the horse power should be reduced by 20% and 21%, respectively if the current catch is to stay at the 2004 level. The DEA results on individual PADNF vessels indicated the capacity utilization was 75% on average, showing some differences in capacity utilization among vessels (31%-100%). The results of the study would be useful for measuring production efficiency in PADNF. They would also provide good policy information for efficient use of resources and capacity reduction levels, which are useful far vessel buyback programs of coastal and offshore fisheries.

Information System is a critical success factor for overcoming the limitations of asset and capacity of Small and Medium Enterprises (SME), and for acquiring competitiveness. Although, the rate of adopting information system by SME has grown, the rate of its utilization has been stagnant. The purpose of this study is to identify the influencing factors that increase SME's information system utilization. We identify perception of strategic value, supplier's support capacity, and organizational characteristic by examining previous researches on information system utilization by SMEs, and verify their the influencing relationship with the information system utilization. This study verifies the research model and hypothesis using structural model. A date-set of 1209 samples from a survey on employees in charge of information system of SME was applied in verifying the research hypothesis. The result of this study shows that the information system utilization influences perception of strategic value and support of supply company, and partly, the structural characteristics. This study presents directions to establish strategy and policy making, and theoretically presents core factors of SME's information system utilization.

This paper deals with storage and retrieval policies for S/R machine with capacity constraints in Man-On-Board AS/RS. It is assumed that storage sequence is based on SFC(spacefilling curve) routine and that storage layout is dedicated by storage policies. We present several heuristic algorithms for storage and retrieval policies which minimize total distance travelled by the S/R machine. These algorithms are based on COI, group COI, frequency of order, similarity between items and capacity of S/R machine. Experimental results of 24 combinastorial policies are provided to illustrate the performance of the heuristics under various rack utilization ratios. In storage policies, the results show that algorithms considering both similarity and frequency are better than those with COI as rack utilization is increasing. And algorithm using group COI is superior to others. In retrieval policies, the method with revision expression is shown to be better than others.

Capacity has always been a major concern in wireless networks. This letter studies the impact of mobility on the overall system capacity in wireless cellular networks. In this letter, we present a simple system model which we developed to capture the inherent relationships among system capacity, new call blocking probability, handoff dropping probability, call terminating probability, and bandwidth utilization rate. We investigate the complex relationship between mobility and capacity-related parameters. Through simulation, we demonstrate that mobility has a significant impact on capacity and is reversely proportional to the bandwidth reserved for handoff traffic.

Cognitive radio (CR) has been proposed to solve the spectrum utilization problem by dynamically exploiting the unused spectrum. In CR networks, a spectrum selection scheme is an important process to efficiently exploit the spectrum holes, and an efficient channel allocation scheme must be designed to minimize interference to the primary network as well as to achieve better spectrum utilization. In this paper, we propose a multichannel selection algorithm that uses spectrum hole prediction to limit the interference to the primary network and to exploit channel characteristics in order to enhance channel utilization. The proposed scheme considers both the interference length and the channel capacity to limit the interference to primary users and to enhance system performance. By using the proposed scheme, channel utilization is improved whereas the system limits the collision rate of the CR packets.

본 연구는 중소기업우선제도의 용어 및 해석이 불명확하여 국가연구개발사업 성과활용이 저해되고 있다는 비판에 따라 관련 용어의 정의 및 해석을 명확하게 하고자 하였다. 첫째, "국내"라 함은 우리나라에서 사업소의 주소나 거소를 두는 것"을 말한다. 둘째, "기술실시능력"이라 함은 "국가연구개발 성과기술을 이용하여 제품의 개발이나 생산 또는 판매활동을 수행하거나, 이에 관한 공정기술의 향상 등 '기술을 사업화 또는 실용화할 수 있는 사실상의 역량"을 말한다. 셋째, "우선적으로 고려"에 있어 "우선"이라 함은 기술실시계약을 체결하고자 하는 기업이 여러 곳일 경우에, 먼저 중소기업에게 계약체결의 기회를 제공하여야 한다는 원칙을 규정한 것으로 특별한 사정이 존재하지 않는 한, 중소기업과 기술실시계약을 하도록 기술보유기관에 대해 일정한 노력의무를 부과한 것이다. "우선적으로 고려"하여야 한다는 반드시 중소기업에게 우선권을 제공하여야 하는 것과는 달리 중소기업과의 기술계약체결을 위한 '노력'을 충분히 한 것으로서 본 규정의 의무조건을 이행한 것으로 간주될 수 있다. 본 연구의 의의는 현행 중소기업 우선제도의 용어 정의 및 해석을 통해 현행 제도의 실무 적용가능성을 높인 점을 들 수 있으며, 본 연구의 한계로는 "기술실시능력 보유 여부에 대한 판단기준", 중소기업 발굴을 위한 '충분한 노력'에 대해 절차와 방법에 대해 일의적으로 명확하게 정의 및 해석하지 못한 바, 이에 대한 후속연구를 기대한다.
