OBJECTIVE: To solve the ESB bus performance and safety problems caused by the explosive growth of the hospital's business, and to ensure the stable interaction of the hospital's business system. METHODS: Taking the construction of our hospital's information system as an example, we used AlwaysOn, load balancing and other technologies to optimize the ESB bus architecture to achieve high availability and scalability of the hospital's ESB bus. RESULTS: The ESB bus high-availability architecture effectively eliminates multiple points of failure. Compared with the traditional dual-machine Cluster solution, the security is significantly improved. The nodes based on load balancing can be scaled horizontally according to the growth of the hospital's business volume. CONCLUSIONS The construction of the ESB bus high-availability architecture effectively solves the performance and security issues caused by business growth, and provides practical experience for medical information colleagues. It has certain guiding significance for the development of regional medical information.

The Ministry of health of Vietnam has considered to apply the information technology (IT) and establish the health information system. The MOH also considered to set up the National health and medical information system as well as strategy of development, objectives, service products and solutions for this system.

To improve and keep the competitiveness, it is necessary to keep pace with available changes in technology, and it is essential to establish the flexible and accurate information system about the disease. And for the accurate decision-making, target setting and prediction of movement, the estimating of the short- and long-term effects of the strategies of disease related service are required. But the limited informations, including all of knowledge of leprosy, make it difficult to estimate them properly. To achieve the more effective leprosy related service, we have to make the effort to crate the more accurate system. To proffer the idea for the development of information monitoring, we present the reviews of some articles about the information theories that used the leprosy related service.

The World Wide Web provides the means for theintegration of clinical computer systems. Extensible Markup Language (XML) and Extensible Stylesheet Language (XSL) are newly developed and standardized Internet protocols. Development of custom data entry forms requires significant programming resources in clinical information system development and management. Visual design tools and a modifiable, template-driven approach may facilitate this process. However, these approaches generally require the predefinition of data form element types. This paper describes an XML/XSL-based technology enabling post hoc definition of elementary and composite data entry form element types.

In this study, using the HL7 protocol, we developed patient management system gateway which is composed of 2 parts; message transferring-receiving and sentcncc generating-parsing part. To make the gateway more transplantable, it was developed on the PC operated with Windows OS. To make the gateway more productive, it was developed with Visual Basic 6.0. The database was built into MS SQL. Server which is most optimized on MS Windows NT system environment. This gateway system has the advantage of easy data-exchange capability between the patient management systems of medical facility and the messages transferred can he managed systematically and he transplanted easily into PC base hospital information system.

PURPOSE: The purpose of this study was to measure accessibility and to examine distribution of restaurants in the local community. METHODS: The target area of this study was two urban areas and a rural area in a city. We collected location information on all restaurants in target areas and classified all restaurants according to Korean food restaurants and Non-Korean food restaurants. We measured restaurant density per 100 m from the residences of the study population and calculated the distance of the nearest restaurant from the residences of the subjects using the Geographic Information System (GIS) analysis method. We compared the accessibility and distribution of restaurants in urban areas with that of the rural area, and compared the accessibility and distribution of Korean restaurants with that of Non-Korean restaurants. RESULTS: Restaurants in urban areas were more dense than those in the rural area, and, in urban areas, restaurants were intensively distributed around the subjects' residence. Also, there were more Non-Korean food restaurants than Korean food restaurants in urban areas, and it was opposite in the rural area. CONCLUSION: It is important that we understood the current state of the restaurant environment in the local community using GIS analysis for the first time in the field of food environment. Further research is necessary on the association of restaurant environments and the dietary life of the population.

With the widespread dissemination of picture archiving and communication systems (PACSs) in hospitals, the amount of imaging data is rapidly increasing. Effective image retrieval systems are required to manage these complex and large image databases. The authors reviewed the past development and the present state of medical image retrieval systems including text-based and content-based systems. In order to provide a more effective image retrieval service, the intelligent content-based retrieval systems combined with semantic systems are required.
