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.

The ubiquitous computing system is expected to be widely utilized in digital home, logistics control, environment/disaster management, medical/health-care services and other applications. The ubiquitous sensor network (USN) is a key infra-structure of this system. Nodes in the USN are exposed to adverse environments and required to perform their missions with very limited power supply only. Also the sensor network is composed of much more nodes. In case some node consumes up its power capacity under a certain required level, the network topology should change and re-routing/ re-transmission of data is necessitated. Resultantly communication protocols studied for conventional wireless networks or ad-hoc networks are not suitable for the sensor network. Schemes should be devised to control the efficient usage of node power in the sensor network. This paper proposes a routing algorithm to enhance the efficiency of power consumption for USN node and analyzes its performance by simulation.

Private participation on public infrastructures projects is being promoted by governments of several developing countries, among them Colombia. As a result, several advantages such as service delivery efficiency, technology application and faster execution of the projects have been recognized. Hence, the Colombian Government is looking for schemes that allow the private investment in projects like hospitals, schools, prisons and public edification. In this paper, experiences in PPP from other countries were analyzed and adjusted to the Colombian environment. As a result, a model adapted to Colombia is presented, based on a well-developed case from Spain. The awarding process is defined by economic criteria, previous compliance of minimum technical exigencies. Once the infrastructure is operating, contractual periodical payments will be done, based on the performance of the facility.

And the ultimate goal of this study is the promotion of the hospice. Methods : The study is of qualitative research and is performed by the literature survey in related fields. And the precedent studies are taken into account also. Through these surveys, crucial items are revealed and the solutions for thorn are proposed. Results : The analysis of the hospice program shows that the MIS can be applied to the hospice with a greater efficiency. This gives the rationale that the MIS for the hospice should be set-up as soon as possible. Conclusion : In establishing the system, recommended is that the hospice model take the gradual development rather than the integrated one from the on-set stage. Further the system design should take several limitations into account to be a realistic one.

This study aimed to develop Chinese restaurant set menu which was proper to tendency of market segmentation by using conjoint analysis. In order to examine tendency of market segmentation, this study investigated the important factors and effective values of whole market and segment market. First, the study found that whole market and segment market seemed to prefer seafood to meat except Cluster 3 (Gentle demand type). Second, regarding efficiency of attribute level, the study found that crap soup is favored over seafood in both whole market and segment market except Cluster 1 (strong demand type). Third, Cluster 1 (strong demand type) showed a high level of efficiency on menu which is mixed with meat and seafood. In Cluster 2 (middle demand type), there was a high level of efficiency in meat menu. In case of Cluster 3 (gentle demand type), seafood menu showed high level of efficiency. Forth, there was a high level of efficacy in rice and western dessert menu on the result of analysis on whole market and segment market. Therefore, this study suggests that the preference of seafood is more higher than the preference of meat. It means that current customers care their health more than they used to be. According to this study, people who want to develop Chinese restaurant menu should focus on seafood more than meat. What's more, marketers of chinese restaurants have to not only present new awareness and fresh atmosphere but also provide typical composition of set menu for target customers.

Background : Gastric cancer is the most common malignant tumor in Korea. Surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for reducing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and the unplanned readmission rate between the pre-pathway group (n=67) and the post-pathway group (n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days (p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was not statistically significant (p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group and 0% in the post-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korean hospital settings.
