As information technology has been developed rapidly, there is growing online medicine service through forming as information technology and medicine information are amalgamated in the medical service field. That acquires real time biological information of patient through a communication network which could be applied into e-healthcare system for a diagnosis and treatment of patient. Because of these reasons, it is necessary for the e-healthcare system to develop. But,the facilities existing in the medical service field could not be used to an on line environment because of the limitation of the time and space. To solve the point of such issue, we propose an auto color analysis system that is a precise and quick to measure health states of user, and the device has the important merit that it is very low cost. Also, the hospital web database and the monitering webpage for a diagnosis have been made for an e-healthcare system.

The objective of this study is to investigate the healthcare status of South Korea and other member countries of the Organization for Economic Cooperation and Development (OECD) using OECD health statistics 2020. We employed the position value for relative comparison index to measure the healthcare status in five following components: demand, supply, accessibility, quality, and cost. The Mann-Kendall test was used to analyze for increasing or decreasing trend of the position value for relative comparison values from 2000 to the recent year. Results showed that Korea was positioned above than the OECD median values in most of components, but lower than the median values in certain indices including healthcare employment, primary care, and mental health care. This study sheds some light on healthcare issues to be improved and the policy-makes can take into account for prior setting process.

Background : Recently, we have experienced various changes in the healthcare environment. Healthcare organizations are facing a financial crisis due to more competitive relationships among themselves as well with low health insurance fees. The purposes of the current study were: (1) to develop a data warehouse-based system for evaluating and monitoring the case management activities, and (2) to measure and analyze its effects. Methods : In order to collect the data for the study, the database on discharged patients was utilized at a university hospital located in Seoul from June 1, 2002 through December 31, 2002. Initially, a data warehouse was built for the case management system. The case management activities were analyzed using structured methodology to establish the case management system. Results : The findings of this study were as follows: (1) A case management system was developed to make it possible to monitor of healthcare quality and resource utilization. The Case management System included monitoring functions regarding utilization reviews, critical pathways, and clinical indicators. (2) Utilizing the case management system, unplanned readmissions were documented among total discharged patients during two months from November 1, 2002 through December 31, 2002. The unplanned readmission rate was 2.3%(276 patients) in total of 11,960 discharged patients. Among them 81 patients(0.7% of total discharges, 29.3% of unplanned readmission) were readmitted to the same physician in charge under the same diagnosis. No significant differences were found in the demographic variables such as gender and age among the patients. (3) After implementing the case management system, 2.9% of average length of stay reduced. Applying cost-benefit analysis, the 2.9% reduction of length of stay represents net profit of ${\backslash}$ 279,592,000 in the year of 2004. In addition, applying value acceleration analysis, cumulative net benefit of ${\backslash}$ 1,481,000,000 was expected by the year of 2007. Also we were able to expect ${\backslash}$ 247,800,000 of cumulative benefit for the prospective 5 years in value linkage analysis. It represents average ${\backslash}$ 787,700,000 of pure net benefit a year. Conclusion : The value of present study would be not only implementing the knowledge management system into the existing case management activities, but also evaluating its effects and estimating its financial benefits. This study suggested that the case management system would be a supportive tool for monitoring and improving the quality of healthcare, and a cost-effective tool for increment of healthcare organization's financial benefit.

This study is to analyse the reimbursement prices of drugs in Japan. Japan has the world's second-largest pharmaceutical market, and the world's largest price-controlled pharmaceutical market. The reimbursement prices of new drugs in Japan are determined by confidential negotiations between the manufacturer and the Japanese Ministry of Health, Labor, and Welfare. Pharmaceuticals account for a larger share of total healthcare expenditures in Japan than in most other major pharmaceutical markets such as France, Germany, United Kingdom and United States. Prescription drugs' share of total healthcare spending has slightly increased in recent years, from 20.2% in 2000 to 21.5% in 2004, the most recent year for which data are currently available. This trend is attributable to the effect of the Japanese rapidly aging population that stimulates demand for healthcare services. There are several method of price setting for drugs as below. First, on the initial pricing of branded drugs, is the similar-efficacy pricing method and cost calculation method. Second is postmarketing price changes which are biennial price revisions under the rule of National Health Insurance. Third is the rule of the generics price. Recently, the generics market is expanded because there are increasing numbers of hospitals by DPCs(Diagnosis-procedure Combinations).

Medical data sharing is increasing due to treatment duplication which increases the cost of medication. Medical healthcare system has been improved to combine with cloud computing. It reduces treatment delay and the medical data error. However, the concern about the privacy protection of medical information is also significant. Medical information is more sensitive than other information because involuntary disclosure can affect in both personal and social life. Privacy cloud brokerage has conquered great attention for solving these problems. Our method provides a security model in the cloud computing environment that facilitates the exchange of medical records between assigned custodians. It allows doctors to obtain a complete patient medical records which can help to avoid duplication, reduce the medical error and healthcare cost as well. In addition, our method offers a trustworthy solution against the privacy violence.

Background: Cancer imposes a significant economic burden on individuals, families and society. The purpose of this study was to estimate the economic burden of cancer using the healthcare claims and cancer registry data in Korea in 2009. Materials and Methods: The economic burden of cancer was estimated using the prevalence data where patients were identified in the Korean Central Cancer Registry. We estimated the medical, non-medical, morbidity and mortality cost due to lost productivity. Medical costs were calculated using the healthcare claims data obtained from the Korean National Health Insurance (KNHI) Corporation. Non-medical costs included the cost of transportation to visit health providers, costs associated with caregiving for cancer patients, and costs for complementary and alternative medicine (CAM). Data acquired from the Korean National Statistics Office and Ministry of Labor were used to calculate the life expectancy at the time of death, age- and gender-specific wages on average, adjusted for unemployment and labor force participation rate. Sensitivity analysis was performed to derive the current value of foregone future earnings due to premature death, discounted at 3% and 5%. Results: In 2009, estimated total economic cost of cancer amounted to $17.3 billion at a 3% discount rate. Medical care accounted for 28.3% of total costs, followed by non-medical (17.2%), morbidity (24.2%) and mortality (30.3%) costs. Conclusions: Given that the direct medical cost sharply increased over the last decade, we must strive to construct a sustainable health care system that provides better care while lowering the cost. In addition, a comprehensive cancer survivorship policy aimed at lower caregiving cost and higher rate of return to work has become more important than previously considered.

The visual sensory information in physical environments can induce or reduce occupants' stress. In healthcare settings, positive environmental stimulations can promote patient well-being by reducing their stress: poor health environments work against a patient's health. Changing the color in a patient room is an inexpensive process and thus finding better colors for healthcare settings is a cost effective method of improving healing environments. Color may have important implications for pediatric patients, but the investigation of Korean populations has been non-existent. The purpose of this study was to investigate Korean pediatric patients' color preferences for patient room design. The color preferences from 50 Korean pediatric patients were recorded and investigated for gender effects. A simulation method was used because of its reliability and feasibility, allowing for investigating the value of color in real contexts and controlling confounding variables. The overall color preferences from Korean pediatric patients showed that they preferred blue the most and white the least. Gender differences were found in red and purple. Girls preferred red and purple more than boys. The results from this study can help healthcare providers and designers better understand appropriate colors for Korean pediatric patient populations.

This descriptive study investigates the need for, satisfaction with, and availability of local healthcare services for elderly individuals. The subjects included 210 individuals aged 65 years over, and data were analyzed using SPSS. The subjects reported the limited availability of local healthcare services but a high level of satisfaction with and a strong need for these services. The subjects used these services mainly for their vaccination and perceived cost-effectiveness as the most important factor motivating their decision to use these services and a lack of publicity as the most important factor discouraging their use. Spouses, jobs, and health conditions showed significant differences in the level of satisfaction and availability, and diseases showed significant differences only in the need. These results suggest that local healthcare centers should provide services that many elderly patients can use through outreach services, connections to local communities, and active publicity instead of expanding service types.

With the help of a small wearable device, patients reside in an isolated village need constant monitoring which may increase access to care and decrease healthcare delivery cost. As the number of patients' requests increases in simultaneously manner, the web service gateway located in the village hall encounters limitations for performing them successfully and concurrently. The gateway based RESTful technology responsible for handling patients' requests attests an internet latency in case a large number of them submit toward the gateway increases. In this paper, we propose the design tasks of the web service gateway for handling concurrency events. In the procedure of designing tasks, concurrency is best understood by employing multiple levels of abstraction. The way that is eminently to accomplish concurrency is to build an object-oriented environment with support for messages passing between concurrent objects. We also investigate the performance of event-driven architecture for building web service gateway using node.js. The experiments results show that server-side JavaScript with Node.js and MongoDB as database is 40% faster than Apache Sling. With Node.js developers can build a high-performance, asynchronous, event-driven healthcare hub server to handle an increasing number of concurrent connections for Remote Healthcare Monitoring System in an isolated village with no access to local medical care.

With the increased attention about healthcare and management of heart diseases, smart healthcare services and related devices have been actively developed recently. R wave is the largest representative signal among ECG signals. R wave detection is very important because it detects QRS pattern and classifies arrhythmia. Several R wave detection algorithms have been proposed with different features, but the remaining problem is their implementation in low-cost portable platforms for real-time applications. In this paper, we propose R wave detection based on optimal threshold and arrhythmia classification through QRS pattern considering complexity in smart healthcare environments. For this purpose, we detected R wave from noise-free ECG signal through the preprocessing method. Also, we classify premature ventricular contraction arrhythmia in realtime through QRS pattern. The performance of R wave detection and premature ventricular contraction arrhythmia classification is evaluated by using 9 record of MIT-BIH arrhythmia database that included over 30 premature ventricular contraction. The achieved scores indicate the average of 98.72% in R wave detection and the rate of 94.28% in PVC classification.
