The purpose of this study was to estimate the population requiring nursing home services for frail elders who received home care nursing services. This study identified the need of nursing home services and the proportion of elders over 60 years of age requiring nursing home services according to the admission eligibility including items with intensity of home care nursing services and the criteria for screening of patients requiring home care nursing services. In this study, survey research design was conducted. A total of 49 home care nurses were collected. They were asked to assess the need of nursing home services based on items with intensity of home care nursing services and the criteria for screening of patients requiring home care nursing services. Using secondary data analysis from the survey on 'The Evaluation of Home Care Nursing Service Program in 1994 in Korea', the proportion of elders requiring nursing home services was estimated. The estimated numbers and proportion of frail elders requiring nursing home services were 169 (86.2%) aged persons among community dwelling elders based on admission eligibility. However, the proportion of aged persons was 68% using the only criteria for screening of patients requiring for screening home care nursing services.

In most countries, mobile subscribers are already experiencing 3G-like services. At the moment of launching 3G services, lots of studies showed estimates of the number of subscribers for 3G services, using long-term demand curves, econometric methods or survey methodologies. Those studies mainly focused on the potential number of subscribers and the point of rapid growth rather than precise estimates for the services. Even though we've already experienced parts of 3G services, full length of 3G services are expecting in near future. Therefore, now we need to have more accurate estimates for 3G services. While we thought that 3G services were moved from 2G, in real place 3G services are being evolved from 2G services. In the process of evolving, regulators' policy affects service demand and diffusion significantly. For the more accurate estimates, we need to consider policy issues which influence service diffusion practically in real place. This study aims to present a model which shows better estimates for 3G services with consideration on policy issues, such as numbering issues, price regulation, and competition policy. The consideration can provide more accurate estimates for 3G services with service providers. The methodology could help academicians In forecasting of similar telecommunications services as well.

The purpose of this study was to analyze the level of the services provision of community health practitioners (CHP) and to find out the influence factors on the services provision of CHP. In this study the dependent variables were the level of community health services(CHS), maternal and child health services(MCH), family planning services(FPS), primary care services(PCS) and the ratios of preventive health services(PHS). And independent variables were predisposing, community demographic and task factors. For this analysis, atepwise regression was used. Data collected for the study on reorganization of health centers organization in 1985 was partly used. The findings of this study can be summarized as follows : First, total variance of independent variables for CHS, MCH, FPS, PCS and PHS are shown 62.5 percent, 58.3 percent, 41.8 percent, 17 percent and 61.9 percent respectively. Second, the most important variables which explain CHS, MCH, FPS, PCS and PHS was ratios of household contacted ($R^2$＝0.289), marital status ($R^2$＝0.177), marital status($R^2$＝0.167), ratios of household contacted($R^2$＝0.119) and management of preventive health services($R^2$＝=0.203) respectively. The independent varivbles used in this analysis presented that the explnining for the provision of preventive health service are more influenced than primary care services. In summary this analysis suggests that the level of preventive health services provision of CHP is low and the provision of primary care services compared with preventive health services are occurred independentely. In the future, the strategies for active preventive services by CHP must to be strengthened.

This study investigates economies of scale, cost complementarity and economies of scope for healthcare organizations using econometric approaches. The economies of scale appear to exist in each service provided by a hospital such as inpatient treatment services, outpatient treatment services, and other patient treatment services, respectively. When we test all services in aggregate level, it also indicates that the healthcare industry on average exhibits the economies of scale of 6 percent, which implies that scaling up hospital sizes will bring substantial cost savings to them Evidence shows that cost complementarity exists between outpatient services and other services for patients and, i.e., these other services for patients experience the reduction in marginal costs as the outputs of the outpatient services increase. For the economies of scope, they are present in most service areas; aggregate level services, outpatient services, and other services for patients, respectively. Inpatient treatment services, however, do not show any evidence of the economies of scope. Results show that the economies of scope are achieved by the general hospital type that provides all service areas such as inpatient treatments, outpatient treatments, and other services for patients. The existence of the economies of scope provides the rationale for extending the existing line of business in a hospital into more diverse areas of services where its benefit comes in the form of cost savings. In sum, it overall provides evidence that the M&As in this industry are encouraged to achieve cost reductions from the economies of scale and scope by changing the size and the output mix.

In this paper, we propose a new personal agent for generating the combinational services from using history of appliances in the home network environment. In such environment, it is required that flexible services can be provided by combining services of appliances and unskillful users can use these services without knowledge. So, it is needed to satisfy following: (1) combinational services can be suggested automatically and (2) the increase of services can be followed. Then, we propose a new personal agent that suggests combinational services by learning the lifestyle. Its learning mechanism is based on Self-Organizing Map (SOM), and can follow the increase of services. We implemented the the agent, and use history of a user for two weeks was made to learn. As the result, we confirmed that the agent can extract services related with time or location and can suggest combinational services.

Recently, smart phones have been widely used in the world. Android phones especially provide existing mobile phone features as well as capability of running enterprise applications and web applications by using services. However, such a linkage has limitations to use Android phones as client devices, there is difficulties in providing services by utilizing characteristics of Android. To solve this problem, we need to invoke services by each other. Currently, the Android platform currently supports inter-process communication IPC. However, there is a limitation that Android services just can invoke remote calls. In this paper, we propose a framework to invoke Android services in java environments. For doing this, we propose methods to make services public and to invoke services in using remote calls and communication methods between java environments and Android.

Web services and their composition (web processes) are promising technologies to efficiently integrate disparate software components over various types of systems. As many web services are nowadays available on Internet, quality of services (QoS) and performance/cost become increasingly important to differentiating between similar service providers. In this work, we introduce sPAC (Web Services Performance Analysis Centre) and show how customers can benefit from sPAC to consider performance in composing and commercializing web services. sPAC 1) helps users to graphically describe the workflow of web services, 2) invokes web services to test out performance for light load conditions, 3) automatically converts the web services and the flow between them into a simulation model, 4) conducts extensive simulations for heavy load conditions and various usage patterns, and 5) reports analysis results and estimation data for the web services.

Purpose: The purpose of this study is to examine the status of care-giving for the demented elderly and to find out the need of community in-house care services-day care services, short-term care services, home help services, and home care services. Method: It analyzed the data of 186 old people having dementia, and caregivers. Data were collected for five days, in September 2002. Results: The caregivers were mostly women and the burden for the care giving was high (87.5%). They used community care services, that is, day care services (26.5%), home care services (21.6%), home help services 00.8%), short-term care services (6.2%). Caregivers' age and education level were significant factors in the demand for day care services. Caregivers' education level was a statistically significant factor in the demand for short-term care services and home help services. Caregivers' age and education level were significant factors in the demand for home care services. Conclusions: It is necessary to expand the financial aid for the active implementation of daytime protection for dementia-patients under medical treatment at home and to promote patients' recovery. It is necessary to enhance home help services and home care services, and to establish many day care centers and short term care centers. Through this, it will prevent caregivers from becoming burnt out due to the burden of care giving.
