Purpose: The purpose of this study is to design an objective and comparable diagnostic system for diagnosing the technology level of military maintenance depots and verify its actual applicability. Methods: Literature Review, Capability Maturity Model Integration, Analytic Hierarchy Process. Results: Military maintenance depot maintenance quality level diagnosis items, Maintenance quality level by maintenance technology area, Guidelines for diagnosing maintenance quality level, Quality level comparison results by area and implications for improvement. Conclusion: In order to systematically evaluate the maintenance quality of military maintenance depots, this study was conducted with the goal of designing an overall maintenance quality diagnosis system, including diagnosis areas, diagnosis items, and a diagnosis score award system, by improving the existing evaluation method. In addition, the newly developed maintenance quality diagnosis system was applied to actual evaluation activities and the results were returned to members, confirming the usefulness of the developed maintenance quality diagnosis system in the field.

Recently, the gene expression data, product of high-throughput technology, appeared in earnest and the studies related with it (so-called bioinformatics) occupied an important position in the field of biological and medical research. The microarray is a revolutionary technology which enables us to monitor several thousands of genes simultaneously and thus to gain an insight into the phenomena in the human body (e.g. the mechanism of cancer progression) at the molecular level. To obtain useful information from such gene expression measurements, it is essential to analyze the data with appropriate techniques. However the high-dimensionality of the data can bring about some problems such as curse of dimensionality and singularity problem of matrix computation, and hence makes it difficult to apply conventional data analysis methods. Therefore, the development of method which can effectively treat the data becomes a challenging issue in the field of computational biology. This research focuses on the gene selection and classification for cancer subtype discrimination based on gene expression (microarray) data.

Modeling product configurations needs large amounts of knowledge about technical and marketing restrictions on the product. Previous attempts to automate product configurations concentrate on representations and management of the knowledge for specific domains in fixed and isolated computing environments. Since the knowledge about product configurations is subject to continuous change and hard to express, these attempts often failed to efficiently manage and exchange the knowledge in collaborative product development. In this paper, XML Topic Map (XTM) is introduced to represent and exchange the knowledge about product configurations in collaborative product development. A product configuration model based on XTM along with its merger and inference facilities enables configuration engineers In collaborative product development to manage and exchange their knowledge efficiently. An implementation of the proposed product configuration model is presented to demonstrate that the proposed approach enables enterprises to exchange the knowledge about product configurations during their collaborative product development.

The effect of parameters on the consequence of the flash fire accident by the release of heavy gas(in this study, xylene vapor) was analyzed. Simulation results showed that the distance with the lower flammable limit($X_{LFL}$) was increased with the increase of the release hole diameter. For the case of the elevated release, $X_{LFL}$ was increased with the increase of the wind speed and the release height, but $X_{LFL}$ was not affected by the wind speed for the release on the ground level. Therefore, the accident in the elevated release was more dangerous than the release on the ground level. In this condition, the release height had more effect on $X_{LFL}$ at the night time than the daytime and in the urban area than the rural area.

Purpose: This paper deals with establishing Korean national standardization policy through a comparative trend analysis of national standardization strategies and each nation's policy environment. It first investigates the standardization strategies including Korea, the United States, Japan and Germany which is currently leading the 4th Industrial Revolution. Methods: This study compares and analyzes national standardization policies that synthesize the determinants of national standard activities using the STEEP, PEST analysis used for policy environment analysis, and National Standardization Model Canvas(N-STD Model Canvas) applying business model canvas. Results: This study confirms the reasoning and operating system of establishing national standard strategy reflecting the social, economic and political situation and the direction of national standard strategy. Conclusion: Based on the results, this study summarized the policy decision factors necessary for establishing the national standard policy and suggested the management plan in the midpoint of view.

무선랜은 특성상 단말의 이동이 빈번하게 발생하며, 핸드오프(Handoff)시마다 반복되는 인증으로 많은 오버헤드를 야기 시킨다. 따라서 본 논문에서는 안전하고 신속한 핸드오프를 위해 IEEE 802.11f의 IAPP(Inter Access Point Protocol)를 사용하며, 제안된 Context Block과 IEEE 802.11i의 4-way handshake만을 이용하여 핸드오프시에 RADIUS 서버와의 통신을 요구하지 않음으로써 효율성을 높였다. 또한 발생할 수 있는 Replay attack과 DoS 공격 등의 문제를 사전에 차단하기 위해 Context Block에 인증필드를 추가함으로써 보안상 취약점을 개선하였다.
