  • 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.

  • The purpose of this study is to analyze the importance and performance of core competencies recognized by Korean sports students and to identify directions and methods for strengthening the competence of sports students in the future direction of future society. The results of analysis of 309 students of sports major students are as follows. First, the importance of core competencies recognized by college students in sports was in the order of self - management capacity, interpersonal capacity, communication capacity, comprehensive thinking ability, resource information technology utilization capability, and global capability. Second, the students' performance of their core competencies evaluated by sports college students was in the order of interpersonal competence, self-management competence, communication competence, comprehensive thinking ability, global competency, and resource information technology utilization competency. Third, the difference between the importance of core competence and the degree of performance was found to be significant in all areas, and the areas of great difference were total thinking, communication ability, resource information technology utilization capacity, self-management capability, Relationship competence. While college students in sports college have relatively high level of interpersonal competence, self-management competence and communication ability, comprehensive thinking ability, resource information technology utilization capacity and global competency are weak. Therefore, It will be able to be reborn as the talent required by society. Therefore, universities need to cultivate competitive sports talent through innovation of curriculum and capacity of faculty, and it should be recognized that this can be linked to the competitiveness of universities.

  • 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.
