Cloud-computing is in the limelight with expectation for cost reduction, because it alleviates the burden of initial investment and maintenance cost and based on pay-as-you-use billing policy. However, many suppliers of Cloud-computing service are suggesting diverse and complicated billing policies without consideration for setting reasonable service billing policy and definite criteria of properties to determine service billing system. So companies willing to use Cloud-computing service are hard to understand the billing system and often spend more expensive cost than necessary. Therefore, this study invested billing system properties of four representative suppliers. Based on these properties of billing system, this study found priorities using AHP survey which conducted to experts who are able to make decisions for adopting Cloud-computing in the company using or willing to use Cloud-computing service. We expect that this study can suggest basic guideline for comparing and analyzing properties of Cloud-computing service with standardized and objective method.

Objectives: In order to cope with the quality and the substantiality issues in long-term care for the elderly, we should have a wider view of long-term system components based on the understanding of health care organizations, management services, support for care providers and beneficiaries, education of the workforce, and management of finance and resources. Methods: For resolving the issues raised and offering guidance in the area of long-term care, we reviewed 20 reports and documents of the government and government-related institutions using the Internet home pages of the Australian government and the related organizations in the health care sector. These organizations are undergoing a huge system reform to implement consumer-directed care since 2015, in the areas of service, resources, finances, organization, and management. Results and conclusions: The study outcomes can have some implications for the long-term care system in Korea based on the differences in the service components. The results can provide basic information for improving the long-term care service, and can have several other implications for long-term care in Korea.

This paper analyzes a discrete-time bulk-service queue with probabilistic bulk size, where the service process is interrupted by a Markov chain. We study the joint probability generating function of system occupancy and the state of the Markov chain. We derive several performance measures of interest, including average system occupancy and delay distribution.

In the rapid growth of cities, road has heavy traffic and many buildings are under constructions. These kinds of environments make more difficulty for a person who is visually handicapped to walk comfortable. To alleviate the problem, we introduce Android based Portable Navigation System to help walking for Visually Impaired Person. It follows, service center give instant real time monitoring to visually impaired person for their convenient by this system. Android based Portable Navigation System has GPS, Camera, Audio and WI-FI(wireless fidelity) available. It means that GPS location and Camera image information can be sent to service center by WI-FI network. To be specific, transmitted GPS location information enables service center to figure out the visually impaired person's whereabouts and mark the location on the map. By delivered Camera image information, service center monitors the visually impaired person's view. Also, they can offer live guidance to visually impaired person by equipped Audio with live talking. To sum up, Android based Portable Navigation System is a specialized navigation system that gives practical effect to realize more comfortable walking for visually impaired person.

School food service must be operated as the part of the education. But it seems that it is not to be considered as an important educational field from the perspective of educational administration. This study was conducted to suggest the effective plan to improve the quality of the school food service system. Questionaries were distributed to 51 administrators and 85 dieticians of primary schools in Incheon area from Aug 7th to Aug 31st 2000. Drawbacks of school food service system cited from the survey results were insufficient support from the authorities both in policy and in budget and shortage of specialists for food service administration. Both dieticians and administrators acknowledged that available facilities required for the school food service were insufficient. 85.9% of dietition and 51.0% of administrators thought dietition of school food service to be suitable for nutrition education. For effective nutrition education, they suggest to have teachers taking in charge of nutrition education, to have teaching system related with school food service and to develope visual auditorial teaching material. For improvement of the quality of school food service, it is necessary to acquire sufficient budget and political support from the government and to have specialists for food service administration. And regulations promoting dieticians to be teachers of nutrition education is required to be introduced in the near future.

This paper proposes a Ubiquitous Henhouse Monitoring System (UHMS) that can not only monitor henhouse's conditions and raising environments, but also control the henhouse remotely by using sensor network technology. The system consists of three layers. The physical layer connects sensors with facilities. The middleware layer processes and manages data collected from the physical layer. And the application layer provides the user with the user requested services. The system provides a real-time monitoring service, a facility controlling service, an expert service, a consumer safety service, and a mobile message service via interacting with components of each layer. Finally, a henhouse model is defined and the relevant system components and the application GUIs are implemented.
