지문샘플의 품질은 지문인식 시스템에서 매칭 성능에 영향을 주는 중요한 요소이다. 지문인식 시스템에서 낮은 품질의 지문영상을 제거하면 인식 에러율이 현저하게 줄어드는 것을 알 수 있다. 본 논문에서는 minutiae 기반의 지문인식 알고리즘을 이용하여 단일 샘플 품질 측정방법에 대한 유효성을 평가하였다. 우선, minutiae 기반의 지문인식 알고리즘의 매칭성능에 영향을 주는 여러 가지 요소에 대하여 검증하고, 다음, 현재 흔히 사용하는 측정방법에 대해 연구하고, 그 중 효과적인 품질측정방법들을 선택하여 NIST, QualityCheck와 Verifinger 5.0을 이용하여 비교 분석 하였다. FVC 데이터베이스로 실험한 결과 단일 측정방법도 매칭성능을 효과적으로 향상함을 알 수 있었다.

The purpose of this research is to find out the impact of quality management and differentiation strategies on customer satisfaction and management performance in family restaurants. In particular, it aims to identify whether such quality management and differentiation strategy have positive influence on customer satisfaction and perceived customer satisfaction as indicated through management performance. For the empirical analysis, a questionnaire survey was applied to a total of 250 customers who experienced family restaurant service in Seoul during the past one year. The model was tested using SPSS 12.0 and visual PLS(partial least squares) programs on a sample of the 198 surveys which showed a 92% usable response rate. The results of empirical analysis showed as follows: 1) quality management has a significant effect on customer satisfaction and differentiation strategies but not significant on management performance. 2) differentiation strategies have a significant effect on customer satisfaction and management performance. 3) customer satisfaction has a significant effect on management performance.

This study also was to analyze the effects of service quality on customers' emotions, behavior intention and local performance in night market, and to provide an effective operation plan. The collected data were analyzed by frequency analysis, factor analysis, reliability analysis and multiple regression analysis using SPSS 16.0 Version, a statistical package program, and various results were discovered. First, all the service quality factors (convenience, food, event program, physical environment) had a positive (+) effect on positive emotion, and the service quality factors except event program had a negative (-) effect on negative emotions. Second, the service quality factors had a partially positive (+) effect on behavior intention and local performance. Third, the positive and negative emotions had a effect on behavior intention, however, the positive emotions had a positive (+) effect on local performance. Consequently, the present study confirmed that service quality in the night market is important factors for emotions, behavior intention, and local performance. Therefore, the findings of this study is capable of being the basic data for revitalizing the traditional market in the future.

Purpose: The purpose of this study is to examine the effects of educational service quality, participation intention, and educational performance in action learning class. Methods: The proposed research model is tested using structural equation modeling for hypotheses based on the data collected from one of action learning class. Results: The results indicate that educational service quality(reliability, assurance, tangibles, empathy, information accuracy, and relationship quality) positively affects participation intention which in turn improve educational performance, including aspects of before and after class of action learning. In addition, participation intention in classroom positively affects educational performance with both groups. For after class of action learning, the result confirms the effect of responsiveness of educational service quality on participation intention, however, in before class of action learning there is not showed a significant relationship. Conclusion: This study would provide useful information and can be applied to the improvement of educational performance through the participation of students by the instructors and the educational institutes who want to apply the active learning forum in classroom.

The purpose of this study is to examine the relationship among innovation activities, innovation performance, and management performance of export firms. I first undertake a review of previous studies related to innovation activity, innovation performance, and export firms' innovation. Based on this, I set up a research model and hypotheses. First, The innovation activity is classified into product innovation activity, process innovation activity, and administrative innovation activity. Innovation performance is divided into product quality improvement and cost reduction. And the business performance is regarded as financial performance of export's firms. This study examined whether innovation activity affect innovation performance such as product quality improvement and cost reduction. In addition, I examined whether these innovation performance affects business performance (financial performance). To achieve this, a total of 368 questionnaires are used in this study and PLS (Partial Least Square) was used to analyze structural equation. As a result, this study shows that product innovation activity have a positive effect on product quality improvement, and process innovation activity also have a positive effect on product quality improvement. However, it was found that neither product innovation activity nor process innovation activity had an effect on cost reduction. And it was found that administrative innovation did not affect product quality improvement, but had a positive effect on cost reduction. Also, it was found that quality improvement, which is an innovation performance, did not affect the financial performance of export's firms, and cost reduction, which is an innovation performance, had a positive effect on the financial performance of the export's firms.

The purpose of this study was 1) to find effects of private Guanxi and organizational relationship on quality of organizational relationship, 2) to find effects of private Guanxi and organizational relationship on performance of distribution channel, and 3) to also find effects of quality of organizational relationship on performance of distribution channel. Apparel manufacturers and distributors in China participated in the study. Random sampling method was used to collect the data. Data from 173 questionnaires were used for the statistical analysis. Factor analysis, Cronbach's alpha coefficient, and regression analysis was conducted. Two factors of private Guanxi were classified(i.e., affective Guanxi, instrumental Guanxi). Three factors of organizational relationship type were identified(i.e., opportunistic relationship, cooperative relationship, vertical relationship). The result indicated that affective Guanxi in terms of private Guanxi positively affected on quality of organizational relationship. Cooperative relationship and vertical relationship in terms of organizational relationship positively affected on quality of organizational relationship. Affective Guanxi positively affected on non-financial performance and financial performance in terms of performance of distribution channel. Instrumental Guanxi in terms of private Guanxi positively affected on financial performance only. Cooperative relationship in terms of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance. Quality of organizational relationship positively affected on non-financial performance and vertical relationship positively affected on financial performance.

Video streaming service over wireless networks is a challenging task because of the changes in the wireless channel conditions that can occur due to interference, fading, and station mobility. To provide an efficient wireless video streaming service, the rate adaptation scheme should improve wireless node performance and channel utilization. Moreover, the quality adaptation scheme should be considered at the streaming application. To meet these requirements, we propose a new cross-layer design for video streaming over wireless networks. This design includes the rate and quality adaptation schemes. The rate adaptation scheme selects the optimal transmission mode and resolves the performance anomaly problem. Based on performance improvement by the proposed rate adaptation scheme, our quality adaptation scheme improves the quality of video streaming. Through performance evaluations, we prove that our cross-layer design improves the wireless channel utilization and the quality of video streaming.
