클라우드 서비스가 확대되고 있지만, 많은 이용자들은 클라우드 서비스의 도입에 어려움을 겪고 있다. 이는 이용자 입장에서 어떤 클라우드 서비스를 신뢰할 수 있는지에 대한 정보가 없기 때문이다. 클라우드 서비스수준협약(클라우드 SLA)은 클라우드 서비스를 제공하는 공급자와 이용자간에 서비스의 품질과 성능 등을 포함한 정성적인 지표와 정량적 지표를 이용하여 협의하는 것이다. 이 연구에서는 클라우드 서비스 사업자의 서비스 수준을 향상하고 이용자를 보호하기 위해 국내 클라우드 산업에 적용할 수 있는 클라우드 SLA를 위한 프레임워크 제안하고 이를 이용하여 국내 클라우드 산업에 적용할 수 있는 클라우드 SLA의 세부 구성항목을 도출하고자 한다. 이를 통해 정부의 "클라우드컴퓨팅 발전 및 이용자 보호에 관한 법률" 체계하의 클라우드 서비스 제공자와 이용자간의 신뢰도 향상을 위한 정책적 활용은 물론 궁극적으로 국내 클라우드 서비스의 품질 성능 수준 향상 및 이용자 신뢰기반 조성을 통해 클라우드 서비스의 활성화를 기대한다.

In this paper we introduce the method, procedure and result of RAM prediction for interlocking system which is applied for AREX signaling system. For RAM prediction, we breakdown the interlocking system to the LRU level and select the LRUs of which failure can cause the service delay. The prediction of reliability is based on the Reliability Block Diagram which is the functional diagram composed of selected LRUs and finally, the availability of interlocking system is estimated from the combination of reliability and maintainability.

Purpose: The purposes of this study were to identify the factors influencing service quality in nursing homes, and to develop an evaluation instrument for service quality. Methods: A three-phase process was employed for the study. 1) The important factors to evaluate the service quality in nursing homes were identified through a literature review, panel discussion and focus group interview, 2) the evaluation instrument was developed, and 3) validity and reliability of the study instrument were tested by factor analysis, Pearson correlation coefficient, Cronbach's ${\alpha}$ and Cohen's Kappa. Results: Factor analysis showed that the factors influencing service quality in nursing homes were healthcare, diet/assistance, therapy, environment and staff. To improve objectivity of the instrument, quantitative as well as qualitative evaluation approaches were adopted. The study instrument was developed with 30 items and showed acceptable construct validity. The criterion-related validity was a Pearson correlation coefficient of .85 in 151 care facilities. The internal consistency was Cronbach's ${\alpha}$=.95. Conclusion: The instrument has acceptable validity and a high degree of reliability. Staff in nursing homes can continuously improve and manage their services using the results of the evaluation instrument.

Different from general operating policies applied for various waiting line situations, two complementary dyadic operating policies are applied alternatingly to a single server maintenance service center model. That is, either of the two dyadic Min (N, T) or Max (N, T) policy is applied to operate such center first and the other operating policy should be applied later, and then the same sequence of both operating policies is followed repeatedly. This operating policy is denoted by the Minimax (N, T) policy. Purpose: Because of the newly introduced operating policy, important system characteristics of the considered service center model such as the expected busy and idle periods, the expected number of customers in the service center and so on should be derived to provide necessary information for determination of the optimal operating policy. Methods: Based on concepts of the newly introduced Minimax (N, T) policy, all necessary system characteristics should be redefined and then derived by constructing appropriate relations between complementary two dyadic operating policies. Results: Desired system characteristics are obtained successfully using simple procedures developed by utilizing peculiar structure of the Minimax (N, T) policy. Conclusion: Applying Minimax (N, T) operating policy is equivalent to applying the simple N and T operating policies alternatingly.
