The integrated management of medical data raised the efficiency of them and improved doctor' s diagnostic ability by processing correct data. Various medical information processing led out the development of new medical technology and is incurring huge changes for the medical examination and diagnosis. In medical database security, both serializability and security must be considered to maintain data consistency and prevent covert channel. In the security environments of heterogeneous medical database systems, the existing local autonomy and the security autonomy as a new constraint are required. This paper defines multilevel secure one-copy quasi-serializability (MLS/1QSR) necessary for concurrency control in heterogeneous medical database systems with replicated data to solve security problem among many objects of medical database systems. The proposed MLS/1QSR neither violates security autonomy nor establishes covert channel for transactions in heterogeneous medical database systems.

Many visualization tools have been designed to aid information processing during whole genome projects. We have developed a trace viewer program, ChroView, which can read a chromatogram file and display the chromatogram traces of the four bases. The program can be used to examine sequencing quality and base-calling errors. It can also help researchers to edit and save base-calling results while browsing the traces. Additionally, this program has a basecalling feature which can produce supplementary data for validation of the results from other base-calling programs.

It is widely accepted that patients with schizophrenia show disturbances in their cognitive function. Recently, due to the increase of the possibilities of therapeutic intervention for cognitive deficits, cognitive rehabilitation is being tried by clinicians in the management of schizophrenia. Our study has considered several questions that have been raised in relation to cognitive rehabilitation. 1) What is cognitive rehabilitation? ; 2) What are its strategies? ; 3) What strategy of cognitive rehabilitation is appropriate to several cognitive deficits? ; 4) What kind of cognitive rehabilitation methods are possible according to the information processing model for schizophrenia? ; 5) What is its clinical considerations? ; 6) On what theoretical basis does the critical view of cognitive rehabilitation have its roots? ; 7) Which direction should it follow? Despite its limitation, there are still great possibilities for the future of cognitive rehabilitation, and we feel that it should be tried for patients with schizophrenia in this country.

OBJECTIVES: Cognitrone Test is one of the computerized neurocognitive tests included in Vienna Test System. It assesses the ability of visuoperceptual analysis, continuous attention and the speed of information-processing. The present study aims at presenting the normative data of Korean adults for Cognitrone Test. METHODS: Cognitrone Test was administered to 353 healthy Korean volunteers aged 18 years and over. Number of correct responses, number of correct Yes-responses, number of correct No-responses, mean time of correct Yes-responses, and mean time of correct No-responses were measured in each individual. Initially the subjects were subgrouped by sex, age and educational level. And the subgroups showing similar levels of functioning were put together and analyzed as a larger unitary group. The subgroups without enough number of cases were excluded from the analysis. RESULTS: Summary scores for five variables of Cognitrone Test were given in the form of percentile and T-score distribution. For three variables representing the correctness of responses, normative data of unitary group(aged 18 to 50 years & educated more than 12 years) were presented. For two variables representing the speed of information processing, normative data of two groups(one; aged 18 to 30 years & educated more than 12 years, the other; aged 31 to 50 years & educated more than 12 years) were presented. CONCLUSIONS: The normative data of Cognitrone Test presented would be very useful in both clinical practice and research.

7.A special instrument for hematocrit measurement.
Chinese Journal of Medical Instrumentation 2005;29(5):352-352
A new instrument for hematocrit measurement is introduced in the paper, which can get the same accurate Hct values while its centrifuging speed is reduced. It integrates high speed centrifuge, automatic data processing and automatic analysis of hematocrit into a system, having more advantages than the traditional measuring devices, such as lower noise, less test errors and better accuracy. Therefore, it can satisfy well clinical applications.

In this article, medical consumable materials supply catalog technology was introduced through the principle, method and application of topic studies, at the same time bar code tags to tag and identify medical consumable materials were introduced. These two techniques established the correspondence between the real supplies logistics and information flow system, provided foundation for medical supplies all process tracking and traceability management. Supply catalog and encoding identification technology provide a new solution for the effective management of medical consumable materials.

10.Simulation of a Multiversion Medical Data Management System for Medical Information Security.
Journal of Korean Society of Medical Informatics 2009;15(4):403-410
OBJECTIVE: If medical information is integrated for management purposes, the efficiency of the system may increase. In addition, diagnostic abilities of physicians may be improved through the increased speed and accuracy of information processing. Medical databases must ensure high performance in terms of speed and reliability. In addition, access to medical information must be restricted to persons with proper authorization to ensure the privacy of patients. METHODS: Thus, the security of medical database systems with multiversion data requires both the existing management system and security policies. RESULTS: This study simulates the performance of a dynamic multiversion data management system in terms of security levels and update operations. CONCLUSION: The results show that a dynamic multiversion data management system increases disk availability more than a double version system. In addition, if the number of security levels is small, throughput will be improved because the security overhead will be low. However, frequent update operations will decrease throughput whenever versions are created at each interval.
