Recent advancement in wireless communications and electronics has enabled the development of low power sensor network. Wireless sensor network are often used in remote monitoring control applications, health care, security and environmental monitoring. Wireless sensor networks are an emerging technology consisting of small, low-power, and low-cost devices that integrate limited computation, sensing, and radio communication capabilities. Sensor network platform for health care has been designed, fabricated and tested. This system consists of an embedded micro-controller, Radio Frequency (RF) transceiver, power management, I/O expansion, and serial communication (RS-232). The hardware platform uses Atmel ATmega128L 8-bit ultra low power RISC processor with 128KB flash memory as the program memory and 4KB SRAM as the data memory. The radio transceiver (Chipcon CC1000) operates in the ISM band at 433MHz or 916MHz with a maximum data rate of 76.8kbps. Also, the indoor radio range is approximately 20-30m. When many sensors have to communicate with the controller, standard communication interfaces such as Serial Peripheral Interface (SPI) or Integrated Circuit ($I^{2}C$) allow sharing a single communication bus. With its low power, the smallest and low cost design, the wireless sensor network system and wireless sensing electronics to collect health-related information of human vitality and main physiological parameters (ECG, Temperature, Perspiration, Blood Pressure and some more vitality parameters, etc.)

Background : This study is to identify the inappropriate hospital services for elderly inpatients over 65 years in general hospital with acute care functioning. Consequently elderly inpatient care and the management of long-term care facilities are key issues for current government health policy. Method : The survey was conducted for two months for all inpatients over 65 in 7 general hospitals, 6 work sampling days randomly selected. In each survey day, the subjective judgement by medical staff on the degree of acute care needs and by nursing unit manager on hospital services of each inpatients was also conducted. Result : The total number of cases collected are 2,541 elderly inpatients, according to subjective judgements by medical staff on inpatient condition. However 46.8% of cases are turned out to be non-acute care group. The frequency of medical services provided to non-acute group are 2~3 vital sign checks per day 78.2%, IV injection 40.1%, antibiotics medication 20.2%. Conclusion : Lots of elderly patients' who are staving in acute hospitals, at present need to be transferred to long-term care facilities. However, there was been shortage of long-term care facilities. It is expected to identify the need of elderly inpatients and therefore, to provide cost-effective, appropriate and good quality health services to elderly inpatients depending on their needs.

This study aims to compare the healthcare status of South Korea and other member of the Organization for Economic Cooperation and Development (OECD) using the OECD health statistics 2021. We used the position value for relative comparison (PARC) index to measure the five elements of the healthcare system, demand, supply, accessibility, quality, and cost. For the statistical analysis, Mann-Kendall test was performed to examine the trend of the PARC values from 2000 to the most recent year. The results showed that supply, demand, accessibility, and quality were above median than the OECD median and the cost was below median. In sectors such as primary care, health employment and mental health care were below median average. With these result, necessary steps for a sustainable healthcare should be taken into effort by policy makers.

Purposes of this study were to identify a hospital-based home care model and to improve the physical, emotional and economical effectiveness of arthritic patients through medical and nursing team approach. The design in nonequivalent control group pretest-posttest design with matched samples in terms of age, sex and disease severity. Fifty two patients in each group were assigned in Seoul, Kyunggi, Kangwon and Kwangju. Before and after 6-month period of home care, level of pain, duration of morning stiffness, Richie Index, ADL, self efficacy, depression, cost expenditure were measured. Nine patients were excluded from the control group in the period of study because of denial of participation. Contents of home care provided to the experimental group include mainly distribution of prescribed drugs, 'assessment of patients' condition and side-reactions of drug. All of the information related to the home care patient were reported to the physician. On the bases of these data, the physician prescribe the specific drugs to each patient. Each patient visited the physician every 2 or 3 month for laboratory test. Patients assigned to the control group visited the outpatient clinic once a month as usual. Null hypotheses were selected because physicians concerned about the ineffective change of patients' conditions due to indirect communication with patients through nurses. Level of pain, Richie index, ADL, self-efficacy, depression, duration of morning stiffness and direct medical cost were the home care provided to them. If a family member accompany in a home care group can save 10,676 Won/month in Seoul, 34,000 Won/month in other districts. Other in-direct cost for transportation and meal can also be saved. In conclusion, those patients with low level of ADL, high level of pain and Richie index, living in the remote area definitely need the home care.

The subject of this study is to review the practical approaches of Home Care Services. Included is a brief overview of its nature, providers of Home Care Services, recent history of Home Care Services, and the impact of the national movement toward cost containment in health care. The data used in this study are obtained from the Elderly Program of the Medical Services and other data on the Home Care Services in Japan. With the growing elderly population in Japan, it is to be expected that the medical care expenditure for this sector will continue to increase. With the aim of keeping expenditure for medical care within reasonable bounds, it is essential that this increasing expenditure on the elderly be used effectively. With the Health and Medical Services Law for the Aged was enforced, therefore, remuneration for medical treatment of the elderly and what is known as the staff placement standard at hospital for the elderly were rationalized. In addition to rationalization from the point of view of medical care supply, it is necessary to guarantee the appropriate treatment within the community and at home for those elderly who are bedridden but not in need of hospital care. For this it is required that Home Care Services, such as health services like visiting guidance by public health nurse in hospital of Health Center. So that the elderly can feel secure in receiving treatment within the community and at home, allowances for guidance on leaving hospital and for intermittent nursing and guidance thereafter are to be newly introduced. Home care Services in one aspect of comprehensive health care, it is comprised of health services provided to individuals and families in their homes. Its purposes include promoting, maintaining and restoring health, specifically maximazing independent functioning and minimizing the disabling effects of illness, including terminal illness. Services appropriate to the needs of clients and their families are planned, coordinated, and delivered by providers organized for the delivery of home health care through the use of contractual arrangement, employed staff, or a combination of the two.

Background: Chronic obstructive pulmonary disease (COPD) is a serious chronic condition with a global impact. Symptoms of COPD include progressive dyspnea, breathlessness, cough, and sputum production, which have a considerable impact on the lives of patients. In addition to the human cost of living with COPD and the resulting death, COPD entails a huge economic burden on the Chinese population, with patients spending up to one-third of the average family income on COPD management in some regions is clinically beneficial to adopt preventable measures via prudent COPD care utilization, monetary costs, and hospitalizations. Methods: Toward this end, this study compared the relative effectiveness of six indices in predicting patient healthcare utilization, cost of care, and patient health outcome. The six assessment systems evaluated included the three multidimensional Body mass index, Obstruction, Dyspnea, Exercise capacity index, Dyspnea, Obstruction, Smoking, Exacerbation (DOSE) index, and COPD Assessment Test index, or the unidimensional measures that best predict the future of patient healthcare utilization, cost of care, and patient health outcome among Chinese COPD patients. Results: Multiple linear regression models were created for each healthcare utilization, cost, and outcome including a single COPD index and the same group of demographic variables for each of the outcomes. Conclusion: We conclude that the DOSE index facilitates the prediction of patient healthcare utilization, disease expenditure, and negative clinical outcomes. Our study indicates that the DOSE index has a potential role beyond clinical predictions.

Background: Information asymmetry between physicians and patients is one of the most unique characteristics of health care. But as consumerism spreads in health care sector, health care consumers are searching comparative information about quality and cost of providers from many information sources. Providing comparative information to health care consumers not only makes consumers choose hospital rationally, but also invigorates the health care market by providers' competition. However there are few studies regarding information searching behavior of health care consumers, then this study is carried out. Methods: The purpose of this study is to understand the information searching behavior of health care consumers based on their characteristics and the types of medical institutions. For this purpose, 313 spinal patients' data of 11 medical institutions (university hospital, spine specialized hospital, clinic) located in Seoul were collected by self-administered surveys. Results: The results of this study are as follows: 1) t-test/analysis of variance analysis showed that according to various characteristics of health care consumers and the types of medical institutions, the level of information searching of each source and the amount of information searching and searching outcomes are statistically different. 2) Regression analysis showed that influence on searching outcomes are statistically different according to the level of information searching of each source and searching content and the amount of information searching has positive effects on searching outcomes. Conclusion: The significance of this study is to provide empirical basis for establishment of health care policy reflecting information needs and preference of health care consumers.

Health policy is directed to equity in the provision of primary care for rural people before the year of 2, 000. This study aimed to define and identify the need for physician's care by using empirical data, and suggested an alternative of the primary care delivery system in rural areas to the government. 1. Twenty percent of the study population wanted to obtain any form of medical care services. : 9.3 percent of the population was in need for physician's care; 15 percent of the need was met by physicians, while 85 percent remained unmet at the time of survey in 1979. 2. For meeting all the need for physician's primary care, 2.9 annual physician visits per capita are demanded. An alternative, which was devised in some favourable way at reasonable cost in rural settings, was suggested. It was to deploy the physician extender such as community health practitioner in the infrastructure of the health care delivery system, whose supervision is provided by physician, based on experience of the KHDI health demonstration project. 3. One physician, two community health practitioners and two community health aides should be assigned in distant locations for meeting all the estimated need for physician's primary care for 10, 000 rural underserved residents.
