Background: This study aimed to develop the models for regional cardiac surgery centers, which take regional characteristics into consideration, as a policy measure that could alleviate the concentration of cardiac surgery in the metropolitan area and enhance the accessibility for patients who reside in the regions. Methods: To develop the models and set standards for the necessary personnel and facilities for the initial management plan, we held workshops, debates, and conference meetings with various experts. Results: After partitioning the plan into two parts (the operational autonomy and the functional comprehensiveness), three models were developed: the 'independent regional cardiac surgery center' model, the 'satellite cardiac surgery center within hospitals' model, and the 'extended cardiac surgery department within hospitals' model. Proposals on personnel and facility management for each of the models were also presented. A regional cardiac surgery center model that could be applied to each treatment area was proposed, which was developed based on the anticipated demand for cardiac surgery. The independent model or the satellite model was proposed for Chungcheong, Jeolla, North Gyeongsang, and South Gyeongsang area, where more than 500 cardiac surgeries are performed annually. The extended model was proposed as most effective for the Gangwon and Jeju area, where more than 200 cardiac surgeries are performed annually. Conclusion: The operation of regional cardiac surgery centers with high caliber professionals and quality resources such as optimal equipment and facility size, should enhance regional healthcare accessibility and the quality of cardiac surgery in South Korea.

Objectives: To determine the factors affecting the assessment of Oriental medical institutions under the Oriental Medical Institution Assessment System and thereupon, provide for some basic data and alternative measures for assessment of Oriental medical institutions. Methods: The researcher sampled 320 people employed by 26 Oriental medical institutions designated as model Oriental medical institutions subject to assessment in 2008 and 2009 and thereupon, used a structured and open-ended survey table for them to collect the data. The size of the final sample was n=302. Results: The Oriental medical institution staff were highly aware of the Oriental medical institution assessment (OMIA), After adjusting the other factors by multiple regression, the factors affecting such recognition were different significantly depending on age (those in their 30's), types of job (nurses and treatment assistants) and locations of hospital (GyeongSang-do). The staff expected the OMIA could helpful for improving facilities and system of hospitals, thus promoting satisfaction of patients. To do so, they felt it necessary to develop an assessment scale reflecting the special conditions besetting the Oriental medical institutions as well as the indices for improvement of Oriental medical service quality. Conclusion: It is hoped that this study will be followed up by future studies which will comparatively analyze Oriental medical institution staff's perception of the assessment system before and after its operation and thereby, suggest some ideal policy alternatives for assessment of the Oriental medical institutions. Furthermore, future studies are requested to research into Oriental medical institution staff's needs and consumers' needs as well in consideration of the characteristics of the Oriental medical institutions and thereupon, suggest some alternatives for continued education, development of the assessment tools, methods and policies.

Modern web services have been broadly deployed on the Internet. Most of these services use multi-tier architecture for flexible scaling and software reusability. However, managing the performance of multi-tier web services under dynamic and unpredictable workload, and different resource demands in each tier is a critical problem for a service provider. When offering quality of service assurance with least resource usage costs, web service providers should adopt self-adaptive resource provisioning in each tier. Recently, a number of rule- and model-based approaches have been designed for dynamic resource management in virtualized data centers. This survey investigates the challenges of resource provisioning and provides a competing assessment on the existing approaches. After the evaluation of their benefits and drawbacks, the new research direction to improve the efficiency of resource management and recommendations are introduced.

Objectives : The purpose of this study was to determine whether the published AMI report card could reduce in-patient mortality, 7-day after discharge mortality, and length of stay (LOS). Methods : Interrupted time-series intervention analysis was used to evaluate the impact of the report card for AMI care quality in November 2005 in terms of risk-adjusted in-patient mortality, risk-adjusted 7-day after discharge mortality, and DRGs case-mix LOS using the claim data of Health Insurance Review and Assessment Service. Results : Public disclosure of AMI care quality decreased risk-adjusted in-patient mortality and DRGs case-mix LOS by 0.00050% per month and 0.042 days per month respectively, however there was no effect on risk-adjusted 7-day after discharge mortality. Patterns of effect of public disclosure on AMI outcomes were a fluctuating pattern on risk-adjusted mortalities and a pulse impact for 1 month on DRGs case-mix LOS. Conclusions : We found the public disclosure of AMI care quality had decreasing effects on risk-adjusted in-patient mortality and DRGs case-mix LOS, but the size of the effect was marginal.

Currently, the development of multimedia communication has progressed so rapidly that the video program service has become a requirement for ordinary customers. The quality of experience (QoE) for the visual signal is of the fundamental importance for numerous image and video processing applications, where the goal of video quality assessment (VQA) is to automatically measure the quality of the visual signal in agreement with the human judgment of the video quality. Considering the codec effect to the video quality, in this paper an efficient non-reference (NR) VQA algorithm is proposed which estimates the video quality (VQ) only by utilizing the distorted video signal at the destination. The VQA feature vectors (FVs) which have high relationships with the subjective quality of the distorted video are investigated, and a hybrid NR VQA (HNRVQA) function is established by considering the multiple FVs. The simulation results, testing on the SDTV programming provided by VCEG Phase I, show that the proposed algorithm can represent the VQ accurately, and it can be used to replace the subjective VQA to measure the quality of the video signal automatically at the destinations.

최근 IP 기반의 멀티미디어 서비스가 증가하면서 IPTV에 대한 수요가 급증할 것으로 예상되고 있다. IPTV는 케이블을 이용하는 기존의 TV와 달리 IP 네트워크 기반의 다양한 서비스 제공이 가능하다. 그러나 IPTV 서비스 품질은 패킷 손실, 지터와 같은 네트워크 열화에 크게 영향을 받기 때문에 언제나 안정된 서비스를 보장하기가 힘들다. 본 논문에서는 다양한 영상 열화에 대하여 주관적 평가를 반영한 IPTV 서비스 품질측정 방안을 도출한다. 이를 위하여 시청자에게 인지적으로 영향을 줄 수 있는 열화 항목을 선정하였으며 선정된 각 열화 항목에 대하여 측정 메트릭을 제안하였다. 각 열화 항목에 대하여 MOS(Mean Opinion Score) 기반의 주관적 평가를 수행하였으며 제안한 메트릭의 측정 결과를 주관적 평가에 사상시켜 주관적 인지 상태를 고려하는 항목별 객관적 품질측정 기준을 도출한다. 다양한 영상에 대한 실험을 통해 개발된 품질측정 메트릭이 주관적 측면을 잘 반영하고 있음을 확인할 수 있다.
