이 연구의 목적은 기존 CT 검사 도구를 확인하여 한계를 파악하고, CT 기반 역량의 의미를 밝히고 이를 통해 올바른 CT 검사도구 개발의 방향을 제시하는 것이다. 그래서 이 연구로 CT 기반 스킬을 통해 CT 역량을 검사할 수 있는 방법을 제시하였다. 이 연구의 결론으로 CT 역량을 검사하는 것은 CT 기반 역량을 검사하는 것으로 CT 기반 하드스킬을 밝혀내어 이를 평가 요소로 적용한다면, 기존 검사도구의 한계를 극복하는 묘책이 될 것으로 판단되었다. 이 연구의 후속으로 CT 기반의 하드 스킬을 찾아 CT 기반 역량을 명확히 규명하고, 이를 바탕으로 검사도구를 개발하여 검증하고자 한다.

In this study, we conducted a survey on the limited examinations of the DR system to the 30 radiologic technologists engaging in the clinical sites and university hospitals in Daejeon metropolitan city from Oct. 15, 2012 to Nov. 15, 2012. Based on the survey results, we propose the conceptual design of a supplementary table for the conventional DR system to extend the examination capability and overcome the limitation of DR system. And, we evaluated the convenience and usefulness of the proposed table by applying it to five subjects. Ten experts were involved to evaluate the clinical usefulness of the obtained images. In this study, the experimental results show the feasibility to overcome the limited examination of the conventional DR system, and the proposed supplementary table may be beneficial to patients and hospitals.

This paper proposes an dffcient method for test pattern generation.Current test pattern genration systems generate a test vester for fault $F_{i+l}$ independently of the computation previously done for faults F1,F2...,Fi The proposed algorithm generates a test vector for fault $F_{i+l}$ by inheriting the test vector for fault Fi. A new test vector is grnerated from inherited values by gradually changing the inhderited values .The inherited values may partially activate a fauog and propagate the fault signal,Normally,this reduses the number of decision steps and backtracks in the second search.Experimental results for well-Known benchmark circuts show that the proposed algorithm is very efficient with small backtrack kimit;in combination eith other algorithms,it is very efficient for arbitrary backtrack limits.

반도체 제조와 같은 대량 생산 시스템에서 제품 검사는 매우 중요란 단계 중의 하나이다. 반도체 제조 공정 내에서의 시각 검사는 현재 사람의 육안에 주로 의존하고 있으나, 회로가 점점 복잡해지고 작아지는 추세에 비추어 볼 때 사람에 의한 시각 검사는 한계에 이를 것으로 보인다. 본 연구에서는 웨이퍼상의 결함을 자동으로 검출하고 검출된 길함을 분류하는 자동시각검사 시스템을 설계 구현하였다.

The pressure safety valve is very important device for securing the safety in the facilities which is operated by high pressure gases. The performance test should be periodically inspected by relate law because the failure of pressure safety valves might be main causes of serious accidents in the industrial fields. Shop test is mainly use for inspecting the performance test of pressure safety valves but the test method is not to be a solution for securing the safety. So, the development of alternative method is required. In this paper, there is a limit to securing the safety if the performance test is with just shop test. The limitation is checked from analysis result based on performance test results of pressure safety valves. The necessity for introducing the in-service test is reviewed to surmount the limitation. As a result, in-service test method should be developed and introduced to improve the inspection efficiency and economical loss. Also, it can be reduce the risk level.

In this study, to analyze the detection of limit for sensitivity of the influenza rapid antigen test kit, the positive detection of limits were analyzed by serial dilution of influenza virus A and B type for five influenza rapid antigen test kits in Korea. As a result of analysis, visual measurement of type A were up to 1:8192 for the Wellsbio product and up to 1:4096 for the II product, up to 1:512 for the I and III products, and only 1:128 for the IV product, and type B were positive for up to 1:8192 for the Wellsbio product, up to 1: 4096 for the II product and up to 1:1024 for the I, III and IV products. For instrument readings with the same specimen, both A and B types were found to be positive for up to 1:8192 for the Wellsbio product, up to 1: 4096 for the II product, and up to 1:2048 for the I product. The sensitivity of the rapid antigen test for influenza differs greatly depending on the sampling area of the patient, infection period, specimen volume, etc. Therefore, it is necessary to observe exactly the collection timing and method of the specimen. And it is necessary further study to improve the sensitivity for influenza rapid antigen test.

As the existing backdoor worked at user mode, which is application mode, it was possible to check the existence of backdoor by the integrity check of system file. However, for the backdoor using kernel module, it is impossible to check its existence by the integrity check of system file. Even various programs were presented to protect this LKM Kernel backdoor, there is limitation in protection as they examine the changes on the system Call Table. This study, recognizing the danger of invasion through such LKM Kernel backdoor, will provide alternative for the limitation which the existing integrity check couldn't prevent intrusion through Kernel backdoor.
