Purpose: We analyzed the need for home care services and awareness of U-healthcare in nurses of the Catholic Parish Home Care Center to link the ubiquitous health care system and the home care. Methods: We recruited 46 nurses from a home care center in the catholic parish of the C medical center from April 4th to June 8th, 2007. Results: The highest needs were 'assessment and diagnosis of the problem', 'management of hypertension & diabetes patients', 'counseling of the patient', and 'counseling of major caregiver and family problems'. Therapeutic nursing showed the highest needs in bedsore care. Nurses want hospital medical records available through the ubiquitous health care system. Conclusion: Home care services are supported from the agency, with high needs in assessing and diagnosing the problem, counseling, and managing of hypertension & diabetes patients. Education and public relations efforts on the U-healthcare system should improve system awareness.

This research is to develop PPG filtering method for respiration measurement in U-Health Care system. Respiration rate was determined by filtering PPG and analyzing its spectrum. Optimal filter of PPG has been selected to get respiration by testing 120 sets of experiment data using 700 filtering cases. As a result, 2nd order Bessel-filter that used band-pass cutoff frequency at 0.175~0.4Hz with second order was good at developing respiration signal. Respiration signal in time domain could be continuously analyzed by converting frequency domain using spectrum analysis. 24 seconds has been found to be optimal time duration of collecting PPG data for determining respiration. Therefore, this study was successful of getting not only heart activity but also respiration by only PPG. Minimal invasive measurement obtaining multi-bio information by one sensor can be expected to apply to U-Health Care and human computer interaction.

The United States has a unique health care system, which is unlikely any other health care systems in the world. The major part of basic functional components of the system -financing, insurance, delivery, and payment- is in private hands. A market-oriented economy invites the participation of numerous private entities that are interested in carrying out the key functions of health systems. Due to this central feature, U.S.health care is not delivered through a network of interrelated components designed to work together coherently. For lack of standardization, the various components of the system fit together only loosely. The involvement of numerous players in the key functions leads to duplication, overlap, inadequacy, inconsistency, and waste, which add to the complexity and also make the system inefficient. Hence, cost containment remains an elusive goals. Moreover, the system falls short of delivering equitable services to all americans, though consumption of health care services is the largest in the world. On the other hand, United States leads the world in the latest and the best in medical technology, medical training, and research. It offers some of the most sophisticated institutions, products, and processes of health care delivery. This article discuss the characteristic features of the U.S. health care system. and its performance, trying to seek its implication on Korean health care system.

본 논문은 만성질환을 갖고 있으면서도 일상생활을 하고 있는 환자들의 응급상황을 신속히 감지하여 능동적으로 대처할 수 있게 하는 u-Health 시스템의 개발에 관하여 기술한다. 기울기 및 진동 센서, GPS, CDMA 통신 모듈 등으로 구성된 PHCH(Personal Health Care Host) 장치에 의해 환자의 위급상황이 신속히 감지되면 현재 환자가 위치한 위치정보를 병원과 보호자의 모바일 단말기로 문자 전송하여 상황에 즉각 대처할 수 있도록 한다. 특히, 시스템은 신경회로망을 이용하여 센서로부터 수신되는 신호 데이터를 분석하고 기절 또는 발작 증상과 같은 응급상황을 신속히 판단한다. 또한 환자의 응급 상황시에 GPS 데이터를 이용하여 환자의 위치를 지도에서 확인할 수 있다. 일상생환을 하면서 항상 주의가 필요한 만성질환자에게 이 시스템을 적용시킴으로써 응급 상황에 신속히 대처하여 귀중한 생명을 구할 수 있을 것으로 기대된다.

New space concept is gaining attention by the change of information and digital technology. It is called a concept of ubiquitous space which is united physical space and digital space. A united into a new space which is called ubiquitous space. It is an emerging concept of new era which is already applied in some part of our daily life the advanced. The advanced technology can help people to realize ubiquitous space including u-health care. Through analysis of characteristics of u-health care space, I am going to suggest new concept of ubiquitous space which is called u-space. It can make change of conventional health care space to vitalized new space and help people's life to be affluent.

The purpose of this article was to evaluate the effects of reimbursement system on the basis of diagnosis-related groups(DRGs). We searched articles which was published from 1970 to 2000 using MEDLINE ； Key words "diagnosis-related groups, DRGs, prospective payment system, PPS. Then we reviewed 97 articles on classifying them into several categories of contents. It seems that the effects of DRGs in controlling hospitals cost in the U.S. was not clear cut. The U.S. Medicare PPS using DRGs remains vulnerable to compensatory increases in ambulatory care and long-term care facilities utilization despite cost per case and cost per admission being reduced. Also some research indicated the possibilities of deterioration in health care service quality. So putting theses results together, much more consideration is needed before the application of DRGs reimbursement system in Korea. Particularly there is the crucial difference between U.S. health care system and Korean, we must be aware of the limitations of DRGs and revise the DRG system to applicable in Korea.orea.

Federal disability law has evolved from several laws geared to protect people with disabilities since the late 1960s and early 1970s. When U.S. Congress passed the Americans with Disabilities Act (ADA) in 1990, no federal statute prohibited the majority of employers, program administrators, owners and managers of places of public accommodation and others from discriminating against people with disabilities. Toward the ends to assure equality of opportunity, full participation, independent living, and economic self-sufficiency for individuals with the disabilities, the ADA pursues three major strategies: Title I addresses inequality in employment, Title II, inequality in public services, and Title III, inequality in services and accommodations offered by private entities. The purposes of the study were to analyze the impact of the ADA on health care for persons with disabilities and to review the ongoing health policy reforms at the federal and state governments. Essential remedies that the ADA contemplates are based on two principles, simple discrimination and reasonable accommodation, which significantly improved access to quality care, especially long-term care, by persons with disabilities. However, the ongoing Medicaid policy reforms to control rising health care costs in the U.S. could threaten the access to care by persons with disabilities in optional groups and to optional care services by persons with disabilities in mandatory groups.
