The advancement in ubiquitous healthcare specifically in preventive healthcare can lead to longer life expectancy especially for the elderly patients. To aid in preventing premature loss of lives as well as lengthening life span, this research aims to implement the use of mobile and wireless sensor technology to improve the quality of life and lengthen life expectancy. The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. Therefore, we propose Context-aware Service of U-Healthcare Application based Knowledge using Ontology in secure health information exchange. This research also applies ontology in secure information exchange to support knowledge base, context modeling, and context reasoning by applying the general application areas for ontologies to the domain of context in ubiquitous computing environments. This paper also demonstrates how knowledge base, context technologies, and mobile web services can help enhance the quality of services in preventive ubiquitous healthcare to elderly patients.

Purpose : This study is a basic research to establish guidelines for healthcare facility in Korean healthcare market. As a first step, it is a main purpose for making beginning point of ICU guideline to set a basic level of ICU facility size and quality by analysis current ICU facilities and existed domestic guidelines : law, criteria of healthcare insurance review and assessment service, credit of Korea institute for healthcare accreditation. Methods : First of all, the all requirements of existed guidelines are put together and summarized. The summary is compared with that of US, UK, and Australia to know its quality difference with international market. In addition, all hospitals in Korean market are classified based on total bed number and ICU bed number to know the most occupied facility size range in the market. Second of all, by comparing 15 ICUs' current setting of the public general hospital, a general condition of ICU facility would be extracted based on function, floor area per bed, services Results : 72.8% of hospitals in Korea are belonging below 500 beds hospital. Among them 200-299 beds hospitals occupied 35.3% and are shown as the most occupied hospital size. As 15 public general hospitals are analyzed, it is clear that the more bed size and services the more ICU area per bed. As a result it is sure that the 300~500 bed may be a clear line as a general ICU condition whose function and bed number relatively consistent in the range. Implications : to keep the qualified medical environment and contemporary hospital trend, the guideline as a minimum requirement keep naturally out from current healthcare settings and should reflect their limit to reconcile with the new trend in the market.

This research is based upon the nursing statistical data published by the Institute of Nursing Policy in 2007, on behalf of Korea nursing association. We analyzed the problems on the healthcare human resources supply in Korea. We suggest that a solution is to adopt immigration policy for foreign workforce employment. The result of the research shows that more than 1,000 nurses are registrated every year except for 2004, according to the yearly status of healthcare jobs. The variance of doctors' registration was quite significant. Compared to 750 registrations in 2004, 4000 doctors were registered in 2002. The healthcare accounts for the property of citizens in terms, which represents the health and lives of everyone, so the country must take all measures to supply the healthcare services in need. Focusing on the underdeveloped region where it is difficult to approach the medical services, the foreign workforce could be added into the healthcare profession field. We conclude that employing foreign healthcare professionals will contribute to the improvement of lives in those people living in underdeveloped region, as well as unity of the local community.

This study aims to analyze the quality and satisfaction of healthcare perceived by patients using hospitals and to provide basic data necessary for expanding and settling Vietnamese healthcare services by analyzing the impact on recommendation intentions. The research method selected one hospital in Vietnam and collected data from patients using the hospital and used a total of 286 effective samples as data for hypothesis verification. The research model and hypothesis verification were analyzed with the statistical data from SPSS and AMOS. The findings show that, first, tangibility, accessibility, and reliability all have a positive effect on the quality of healthcare. Second, it has been shown that only accessibility among the quality of healthcare has a positive effect on recommendation intentions. Third, customer satisfaction has been shown to have a positive effect on recommendation intentions. Fourth, when looking at the mediating effect, reliability among the quality of healthcare was shown as a full-mediated effect, but accessibility was shown to have a partial mediating effect and tangibility to have no mediating effect. Contact management is important because customer satisfaction is highly regarded when customers feel positive emotions at the interface from the provision of convenience facilities that support medical services to the reduction of waiting time for patients, employees kindness, treatment, medication, and inspection. It is also confirmed that the demand for convenient and rapid use of hospitals is increasing in Vietnam. In addition, if customer satisfaction is increased through friendly medical staff's response, the intention of recommendation will be even greater.

This study aims to develop strategic plan for enactment of national license of hospital administrators. To effectively control healthcare cost and mange healthcare organizations, the enactment is an inevitable process. Based on literature reviews, cases of similar licences in advanced foreign countries, and a survey of 200 experts in healthcare fields, this study provide a strategic map how to proceed the enactment.

Over the last few years knowledge management has become more and more impotant part of the in healthcare practices. Therefore the healthcare organisatiions have also begun to apply knowlege management strategies. To address this issue of the lack of true knowledge management in healthcare enterprises, we propose a framework for common Healthcare Knowledge Management. This framework is made up of two suites of applications and services, i.e. the intelligent agent-based knowledge management application suite and the strategic visualisation, planning and coalition formation service suite.

The medical industries are integrated with information technology with mobile devices and wireless communication. The advent of mobile healthcare systems can benefit patients and hospitals, by not only providing better quality of patient care, but also by reducing administrative and medical costs for both patients and hospitals. Security issues present an interesting research topic in wireless and pervasive healthcare networks. As information technology is developed, many organizations such as government agencies, public institutions, and corporations have employed an information system to enhance the efficiency of their work processes. For the past few years, healthcare organizations throughout the world have been adopting health information systems (HIS) based on the wireless network infrastructure. As a part of the wireless network, a mobile agent has been employed at a large scale in hospitals due to its outstanding mobility. Several vulnerabilities and security requirements related to mobile devices should be considered in implementing mobile services in the hospital environment. Secure authentication and protocols with a mobile agent for applying ubiquitous sensor networks in a healthcare system environment is proposed and analyzed in this paper.

Data and network security for e-Healthcare Systems are a primary concern due to the easiest deployment area accessibility of the sensor devices. Furthermore, they are often interacting closely in cooperation with the physical environment and the surrounding people, where such exposure increases security vulnerabilities in cases of improperly managed security of the information sharing among different healthcare organizations. Hence, healthcare-specific security standards such as authentication, data integrity, system security and internet security are used to ensure security and privacy of patients' information. This paper discusses security threats on e-Healthcare Systems where an attacker can access both data and network using masquerade attack. Moreover, an efficient and cost effective approach for countermeasures is discussed for the delivery of secure services.
