The enormous budget of government and manpower are invested to the government funded institutes every year. The R&D investment focused on input has to be turned toward the investment based on the effectiveness of R&D activities. Measuring the efficiency of research activities is required in order to evaluate the effectiveness of R&D investment in these institutes. The purpose of this paper is to evaluate the relative efficiency of research activities performed in 19 government funded research institutes. CCR/BCC model and DEA/AR model were applied to get the relative efficiency of 19 institutes. Assurance regions for the weight of output attributes were obtained by using the underlined concept of the analytic hierarchy process (AHP). We used input and output data items describing research activity of 19 government funded research institutes. The results of this study are expected to become a basis of the R&D investment decision of the government.

Unlike physical goods, service consists of a chain of activities that allow the service to function effectively. In order to enhance customer experiences, service providers should innovate service processes. Service innovation refers to new or considerably changed service processes that deliver added value to the customers. Unfortunately, many of the activities are invisible to both service providers and consumers. In terms of service innovation, service visualization is very critical. When we visualize the current service process, we can identify its problems. This study suggests service blueprinting as a service innovation methodology. In order to demonstrate the usage of the methodology, this study examines departure/arrival services at the airport.

Objective:The purpose of this study was to test the hypothesis that cardiovascular risk is associated with cognitive impairments in clinically stable late-life depression. Methods:A total of 59 clinically stable late-life depression patients over age 60 were enrolled in a cross-sectional study. Evalu-ation tools used in this study include Hamilton Rating Scale for Depression, Geriatric Depression Scale, State-Trait Anxiety Inven-tory, the Framingham general cardiovascular disease risk profile and the cognitive function battery designed for this study. Corre-lation analysis, analysis of variance and analysis of covariance were performed. Results:Patients with higher cardiovascular risk performed significantly poorer in the domains of executive function and short-term or long-term memory. In models adjusted for age, sex, education, 10% higher cardiovascular risk was associated with poorer executive function. Conclusion:Our findings suggested that cardiovascular risk could be a significant factor associated with poor executive func-tion in clinically stable late-life depression and the management which is necessary as a component of treatment planning. This pi-lot study provided good prospects for future studies to document this relationship on larger samples.
