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.

Purposes: The purposes of this study are to describe the health problems experienced by VLBW premature infants and their health care services utilization during the first year of life Method: Eighteen mothers of VLBW premature infants completed a survey questionnaire, asking socioeconomic/demographic information, health/developmental problems experienced by their infants, and their use of health care services. Results: Of the 18 infants, 78% experienced respiratory problems such as cold/running nose and wheezing during the first year and 33% experienced gastrointestinal problems such as vomiting, diarrhea and constipation. Twelve (67%) infants visited the emergency department at least one time and 10 infants (56%) were hospitalized at least once during their first year of age. Interestingly, infants without chronic lung disease visited the emergency department more than infants without chronic lung disease (p=.213). Infants living in non-disadvantaged neighborhoods were hospitalized more than infants living in disadvantaged neighborhoods (p=.000). Conclusions: Health care providers should initiate educating mothers, particularly those living in disadvantaged neighborhoods, about post-NICU discharge health care needs of their VLBW premature infants while their infants were still in the NICU so that unnecessary visits to the emergency department and rehospitalizations can be possibly prevented.

Purpose: This study was done to learn from the development of rural health nursing in developed countries. Method: A literature search was done using keywords such as "rural and nursing" or "rural and health" from the database CHINAL and website of institutions related to rural health and nursing. Results: In Australia, the type of rural health institution was categorized according to the population size and nursing service was done differently according to area. It is unique to Canada to have the Canadian Association of Rural and Remote Nursing, which published the survey report "the Nature of Nursing Practice in Rural and Remote Canada". In the U.S., the role of nurse practitioners in rural communities was relatively well developed and a diverse nursing care model was demonstrated. To improve health care access in rural communities, financial and political support by the governments has been part of long-term plans in the three countries. Conclusion: It is very informative to identity the difference and similarity in rural health nursing in three developed countries. For the future development of Korean rural nursing, suggestion can be made in terms of research, education and policy development.

Nursing centers are nurse-managed organizations that give the client direct access to professional nursing services. Academic nursing centers are faculty-created and -organized nursing centers integrated into nursing school or cooperated with community nursing center. Academic nursing centers are needed for providing services to the forgotten or underserved populations in the community, providing learning opportunities for nursing students and practice opportunities for faculties. The intent of this study is to identify the elements needed in developing process and operations of acedemic nursing center for elderlies and the disabled, and to present the desired model for academic nursing center. The processes of my study were : 1) The articles of the academic nursing centers in U. S. were reviewed and analysed. 2) The academic nursing center for elderlies and the disabled was developed and operated in my paper. 3) Desired model for academic nursing center was presented in my paper. The followings are the results of my study: 1. Elements needed in developing process of academic nursing center were philosophy and goals, the community support, assessment of the validity of the service and health needs, identification of the service contents, roles and responsibilities, communication lines, finances for facilities and operations, cooperation with resources, and developing record system. 2. Elements needed in operations of academic nursing center were the structural organizations, realization of the above philosophy and goals, development of policy and nursing standards, faculty participation, continuity of services, and financial solutions. 3. The desired model was presented according to the process and operations.

Background : Utilization review has been adopted as a vehicle for cost and utilization control of health care services. Its role was further stressed and expanded through the establishment of Health Insurance Review Agency in 2001. This article is to introduce concept, activities, and effect of utilization review based on the experiences of U.S. and to suggest important characteristics for ideal utilization review activities at the national level in Korea. Method : Twenty-five articles related with utilization review were reviewed after being selected through web site search through Med Line and Richis. Result : Utilization review was introduced mainly for health care expenditure control either by insurer, provider or the third parties under the pressure of increasing health care cost. It's activities can be categorized to prospective, concurrent and retrospective review according to the time of service provision. Based on most of studies, utilization review has been effective in controling rising health care cost and utilization. However it's effectiveness assumes a reimbursement structure of managed care like capitation payment. More worse, it is still unknown it's effectiveness on quality of care. Conclusion : Utilization review should be employed to increase the cost effectiveness of medical care by optimizing quality and patient's outcomes while also attempting to reduce the use of resources. So, it should consider outcomes before expenditures, check for both under and over-use, and construct an structure in which consumption is reduced equitably. Aggressive adoption of utilization review in Korean health care setting with fee-for-service reimbursement structure might not be a cost-effective approach before adoption of prospective payment system such as D.R.G. and capitation.

Ubiquitous home is emerging as the future digital home environments that provide various ubiquitous home services like u-Life, u-Health, etc. It is composed of some home appliances and sensors which are connected through wired/wireless network. Ubiquitous home services become aware of user's context with the information gathered from sensors and make home appliances adapt to the current home situation for maximizing user convenience. In these context-aware home environments, it is the one of significant research topics to predict user behaviors in order to proactively control the home environment. In this paper, we propose Multi-Level prediction algorithm for context-aware services in ubiquitous home environment. The algorithm has two phases, prediction and execution. In the first prediction phase, the next location of user is predicted using tree algorithm with information on users, time, location, devices. In the second execution phase, our table matching method decides home appliances to run according to the prediction, device's location, and user requirement. Since usually home appliances operate together rather than separately, our approach introduces the concept of mode service, so that it is possible to control multiple devices as well as a single one. We also devised some scenarios for the conceptual verification and validated our algorithm through simulations.

It is important for the strategy of service to provide the health information in the environment that the healthcare has been changed focusing on the preventive medicine. Recently, the various applications of u-healthcare have been presented by researchers. In this paper, we proposed the health information monitoring system using the context sensors based band. By wearing the proposed hand, the health status is gathered and vital signals are transmitted to the connected UMPC. It can be easily monitored according to the user locations in real time. To provide the health index according to the temperature, the air conditioning, the illumination, the humidity, and the ultraviolet rays, we use the various XML links extracted from RSS of the Korea Meteorological Administration. The health information is analyzed in terms of factors, such as, the asthma index, the stroke index, the skin disease index, the pulmonary disease index, the pollen concentration index, and the city high temperature index. Ultimately, this paper suggests empirical application to verify the adequacy and the validity with the proposed system. Accordingly, the satisfaction and the quality of services will be improved the healthcare.
