A diversity of wireless networks, with rapidly evolving wireless technology, are currently in service. Due to their innate physical layer vulnerability, wireless networks require enhanced security components. WLAN, WiBro, and UMTS have defined proper security components that meet standard security requirements. Extensive research has been conducted to enhance the security of individual wireless platforms, and we now have meaningful results at hand. However, with the advent of ubiquitous service, new horizontal platform service models with vertical crosslayer security are expected to be proposed. Research on synchronized security service and interoperability in a heterogeneous environment must be conducted. In heterogeneous environments, to design the balanced security components, quantitative evaluation model of security policy in wireless networks is required. To design appropriate evaluation method of security policies in heterogeneous wireless networks, we formalize the security properties in wireless networks. As the benefit of security protocols is indicated by the quality of protection (QoP), we improve the QoP model and evaluate hybrid security policy in heterogeneous wireless networks by applying to the QoP model. Deriving relative indicators from the positive impact of security points, and using these indicators to quantify a total reward function, this paper will help to assure the appropriate benchmark for combined security components in wireless networks.

The KJC and KCI services operated by the National Research Foundation of Korea (NRF) need to refer to the global citation index database to set the service direction that researchers want and develop new functions. Therefore, in this study, the usability of Korea's KJC and KCI web databases was evaluated. In addition, FGI verification was performed for a group of experts on KJC and KCI improvement measures derived by academic information experts. The evaluation committee consisted of the researcher group, the society related group, the publisher (academic information distribution organization) group, and the policy-making organization group. A total of 16 experts performed usability evaluation and service improvement proposals for KJC and KCI services. As a result of usability evaluation of KJC and KCI web database using SUS measurement tool, KJC service was evaluated as 73.44, and KCI service was evaluated as good as 64.38. KJC improvement proposals were evaluated positively with 4 points or more for all improvement items, and KCI improvement proposals were positively evaluated with 3.5 points or more for all improvement items. Overall, KJC and KCI error improvements were evaluated with a score of 4 or more, showing strong affirmations. In the future, it is hoped that the improvement proposals and improvements proposed in this study will be applied to the development of KJC and KCI services, so that more quality services will be used by domestic researchers.

The purpose of this study is to provide basic material about the improvement method of the hospital evaluation system by grasping recognition, corresponding behavior to evaluation, influence and problems about the hospital evaluation system with respect to the employee of mid sized hospitals having relatively poorer environment. In this study were used 518 questionnaires to hospital employee working at 20 general hospitals in Pusan, Kyungnam with less than 500 beds and having experience of the hospital evaluation during 2005~2007. As a result of the research, they felt the investigation tool used for the hospital evaluation has too many items and it could be difficult to reflect characteristics of each hospital. It appeared that utilization of the report result after the hospital evaluation was helpful for grasping a part necessary for hospital improvement and the present level of hospitals and increase of interest about medical service quality improvement of the a hospital director or hospital employee. They trusted the result of the hospital evaluation to some degree, and recognized it helps the patients to select a hospital and increase rights-to-know. Hospital employee recognized the necessity and showed high interest and participation, but they didn't sympathize in the propriety and the feasibility of the hospital evaluation items. High degree evaluated hospital employee receive hospital evaluation system positively and think hospital services to be improve after taking hospital evaluation. The hospital evaluation should make the hospital to effort to achieve medical quality improvement to its purpose. Also, systematic reformation will be necessary to reflect characteristics of the hospital that has relatively small scale or locates in poor environment.

본 연구의 목적은 이용자의 관점에서 노인장기요양보험 방문요양서비스 기관 평가의 효과성을 확인하는 것이다. 이를 위해, 전라북도 내 지역별(14개 시·군) 할당표집을 통해 수집한 이용자(266명) 설문자료와 기관(47개) 자료를 결합하여 다층모형으로 분석하였다. 주요 연구결과는 다음과 같다. 첫째, 5개 평가영역 중 이용자에게 권리의식을 갖게하고, 이용자를 존중하는지에 대한 '권리·책임' 영역의 점수가 높을수록 서비스 품질과 만족도도 높게 나타났다. 둘째, 5개 평가영역 중 '권리·책임' 영역과 '급여제공결과' 영역이 충성도에 영향을 미치는 것으로 나타났다. 셋째, '기관운영', '환경·안전', '급여제공과정' 영역은 서비스 품질, 만족도, 충성도에 영향을 미치지 않는 것으로 나타났다. 이러한 결과를 바탕으로 형식적이고 정량적인 평가지표보다는 이용자가 인식할 수 있고, 방문요양서비스의 기본 목적에 충실한 내용으로 평가지표를 재구성할 것 등을 제안하였다.

Purpose: This study was conducted to explore the meaning and contents of high-quality aged care facilities and provide basic data for evaluation of service quality in such facilities. Methods: The focus group interviews and participants consisted of two user groups, for a total of 16 family caregivers of the elderly living in facilities and four service provider groups, for a total of 26 chief managers and caregivers working in aged care facilities. All interviews were recorded and transcribed as they occurred. Content analysis was used and debriefing notes were referred to in order to analyze the data. Results: Four themes of a high-quality aged care facility emerged from the analysis; 1) a place to rest for comfortable later years; 2) systematic value-based management; 3) providing professional care; 4) comprehensive service provision in response to diverse needs. Conclusion: The findings of the study showed the importance of client centered care and ethical mindset of providers, which had not been included in the existing quality evaluation programs. Based on these results, medical treatments, end-of-life care and more comprehensive and extended services including family care need to be provided in facilities to ensure good quality aged care.

자동화된 서비스 식별 및 품질평가는 서비스 지향 컴퓨팅의 주요한 특징 중의 하나이며, 특히 최근 몇 년간 이에 관한 활발한 연구가 진행되고 있다. 그러나 대부분의 연구는 어플리케이션 서비스 식별 및 품질평가에 집중되어 있으며, 비즈니스 프로세스로부터 비즈니스 서비스를 식별하고 품질평가를 자동화하는 방안은 제시하지 못하고 있다. 일반적으로 비즈니스 서비스 식별은 전문가에 의해 수작업으로 이루지기 때문에 많은 비용과 모호성을 유발할 수 있을 뿐만 아니라 작업 실수 및 오해로 인해 낮은 품질의 서비스 설계로 이어질 수 있다. 본 연구에서는 전사적 아키텍처를 기계가 이해할 수 있는 지식데이터베이스로 활용한 비즈니스 서비스 식별과 품질평가의 자동화 방안을 제안한다. 제안 방안의 효용성을 보이기 위해 미국 국방부의 전사적 아키텍처를 활용한 실험결과를 제시한다.

By using the formerly established SERVQUAL Model, measurement methods and determinant variables in the other papers for the Service Quality, this study first focuses to find out the difference consumers' evaluation between before-experience and after-experience of the educational service, and second, to examine the difference consumers' evaluation between before-experience and after-experience of the educational service according to pre-recognition degree for the subjected educational service quality. The results are derived as follows. 1. As a consequence of the simulation, the consumers distinctly tend to recognize importance of human concern and visual aspect after experience of educational service. 2. Between the group with more pre-recognition degree and less pre-recognition degree for the subjected educational service quality, have no difference.

In this paper, We develop performance evaluation model for Twin fork Automated Storage/Retrieval systems. The system is modeled as a modified bulk service queueing system consisting of one exponential server with limited system capacity. The differance between this model and general bulk service queueing model is the inequality of transition service rate of each stage. The ejective of this model is to provide system characteristics for Twin fork AS/R system design problems, which are the number of customers in system, wait time in system and queue, the system queue size.
