  • In this paper, a new design of a triple-erroe-correcting (TEC) Reed-Solomon decoder is presented based on direct decoding method which is more efficient for the case of relatively small error correction capability. The proposed decoder requires only 9 GF(2m) multipliers in obtaining the error-locator polynomial and the error-evaluator polynomial, whereas other decoders needs 24 multipliers. Thus, the attractive feature of this decoder is its remarkable simplicity from the point of view of implementation. Futhermore, the proposed TEC Reed-Solomon decoder has very simple control circuit and short decoding delay. Therefore this decoder can be implemented by simple hardware and also save buffer memory which stores received sequence.

  • Most of universities have carried out course evaluation to improve students's satisfaction for the established lecture and apply the performance appraisal for professor. But, course evaluation depends on many variables such as class size, type of lecture, evaluator's grade and so on. As the results, such variables lead to serious bias which makes lecturers distrust the course evaluation results. In this paper, we compare some equating methods for the course evaluation and the efficiencies for some equating methods. And we will recommend one of them which has best efficiency. Also we give the example to which the method is applied.

  • Most of universities have carried out course evaluation to apply the performance appraisal for professor. But, course evaluation depends on characteristics of each class such as class size, type of lecture, evaluator's grade and so on. As the results, such characteristics of each class lead to serious bias which makes lecturers distrust the course evaluation results. Hence, we propose a equating method for the course evaluation by regression analysis which use stepwise variable selection. And we compare proposed method with the other method by Cho et al. (2009) with respect to efficiencies. Also we give the example to which the method is applied.

  • Purpose: The purpose of the study was a quantitative evaluation of common errors in digital impression procedure using CEREC$^{(R)}$ AC system. Methods: Two-hundreds digital impression data comprising 174 inlays, 26 onlays by CEREC$^{(R)}$ AC in-office CAD/CAM system were obtained from a dental clinic. One evaluator assessed errors of the digital impression data and divided into five categories of errors: inappropriate scanner positioning (ISP), improper handling with a scanner (IHS), irregular powder arrangement (IPA), improper cavity preparation (ICP), and insufficient scanned data (ISD). Results: The most common errors were IPA(21%), and ISP and ISD were followed by 17% respectively. IHS was found in 14.5% of all digital impression data. ICP comprising only 6.5% was the rarest. Conclusion: Most errors were due to inaccurate manipulation with an intraoral scanner or improper cavity preparation for scanning. A deliberate manipulation to prevent common errors mentioned may deliver an optimal result in the digital impression procedure.

  • Purpose: The purpose of this study was to develop a computer access assessment tool for persons with physical disabilities and to evaluate reliability and validity. Methods: We developed a computerized Computer access Assessment Program (CAP) through many kinds of literature review and tools analysis for evaluation of computer access, task analysis of fundamental input devices operation and expert review. The CAP data were obtained from 105 normal university students and 16 students with physical disabilities. The test items of CAP are composed of four timed mouse tasks, four timed keyboard tasks, and a timed scanning task. Thus, the software measures user performance in skills needed for computer interaction, such as keyboard and pointer use, navigating through menus, and scanning. To determine the validity of these measurements, we compared data on CAP reports to a Compass report. Compass software allows an evaluator for assessment of an individual's computer input skills. Results: Results of this study showed that the CAP had high internal consistency, reliability of test-retest, concurrent validity, and convergent validity. Conclusion: Therefore, the CAP is appropriate for evaluation and determination of computer access skill of persons with physical disabilities. It is possible to get clear quantitative data on performance when providing computer access services if you can use the CAP data. Using this quantitative evidence, insights can be gained into the specific nature of any difficulties experienced by persons with physical disabilities and find wise solutions.

  • As one of methodological approaches for objective and systematic evaluation for rural resources, a sequential system for significance determination of resources items was formulated using AHP (Analytic Hierarchy Process) as the base technique. By the system constructed in this study, the significance values were calculated for all items of standard goal system which had been presented in the first phase- paper of research works for rural resources evaluation. The results analysed and obtained in the study are summarized as follows; 1. In case that the number of resources items for evaluation are relatively large, stepwise matrix method is considered as the better one for pair-comparison works in view of evaluator's convenience and consistency. 2. The significance valuing results for most resources items showed a considerable difference between characteristic areas, especially in aspects of land and human resources, so being considered as wet reflecting the specific areal varieties, 3. On land resources, the items for industrial development and land use showed higher significance value, while natural environment resources the items for ecological varieties and on human resources the items for artificial facilities. However, lower-valued ones were the items for mineral stocks in land resources, for control and protection in natural environment resources and for lower-level culture heritage respectively.

  • This study addresses the evaluation criteria of multimedia authoring tools(MATs), the way which decision-maker can exclude outlier matrix from group using the concept of the compatibility index, and how AHP can be applied to the selection of MATs in a group decision-making environment. The AHP technique allows an evaluator to quantify the relative importance of elements at each hierarchy and to calculate the composite relative weights for each product(i.e. MATs). This decision process allows setting to priority of the MATs based on the AHP. The results indicated that technical ability of MATs was the most significant factor in affecting their decision, trailed by managerial efficiency and vendor support. To the experts, multimedia data support was the less important than development interface. Also, the results indicated that product A(0.510) was their first choice, trailed by product C(0.286) and B(0.204). Assessing the composite relative weights revealed that expert group's members were consistent with the rankings of decision variables(evaluation criteria variables) statistically in selecting their MATs. Therefore, we believed that expert group's members have achieved sufficient agreement to permit the use of geometric mean to average the group's preference without obscuring the differences of individual opinions.

  • Purpose: This study examined the definition of care coordination, and the activities and roles of nurse care coordinators. The study also proposed suggestions for establishing and expanding the role of nurse care coordinators in community health practice. Methods: This study derived its conclusions by conducting a literature review. Results: The definition of care coordination is a comprehensive concept that includes case management and transitional care, and can be summarized as organizer and integrator of care. According to the literature review, 12 activities and 6 roles of nurse care coordinator were identified such as a collaborator, an individualized care planer, an educator/counselor, a direct nursing care providers, a population care coordinator, and a program evaluator. Training for nurse care coordinators is currently addressed in the Primary Medical Chronic Disease Management Program. Visiting nurses working at the Eupyeong-dong visiting health and welfare service are expected to act as nurse care coordinators, and the role of nurse care coordinators will, in the future, gradually increase in various nursing facilities. Conclusion: In addition to developing competencies to act as a nurse care coordinator, there is need for approaches to health policy that develop both independent role and population focused role as care coordinators.
