국제공통평가기준(Common Criteria)2.1을 기반으로 한 국제공통평가인정협정(Common Criteria Recognition Arrangement)은 21세기 정보보호 산업 전반에 수출입 장벽 및 국제적 표준으로 자리매김 할 것이다. 이미 국제공통평가상호인정협정(CC-MRA)에서부터 적극적으로 기술을 축적하고 세계적 표준을 선도한 미국, 캐나다, 영국, 독일, 프랑스 등의 주요 선진국들은 국제공통평가인정협정 인증서발행국(CCRA-CAP)으로서의 우월적 지위를 확보한 상태이다. 이에 본 연구는 CCRA-CAP국가들에 대한 스킴(Skim) 분석을 통하여 우리나라 의 스킴 개발이 국제적인 선도국과 비교하여 어떤 차이를 보이는지와 우리나라의 문제점을 도출해보고자 한다. 이를 통하여 향후, CCRA-CAP국가로 세계적 평가, 인증체계의 선도국이 되기 위한 준비과정에서 얻을 수 있는 통찰력과 시사점을 제공하고자 한다. 본 연구에서는 여러 스킴 중 정보보호시스템 평가, 인증 제도 관련 기관 책임 및 임무에 관한 1번 스킴을 주요 논의의 대상으로 하여 분석 연구한다.

In this study, we write down the definitions, their causes and the techniques of analysis as a theoretical consideration of common cause failures, and investigate the limitation and the importance of the common cause failures by applying to the analysis on the fire protection as a representative safety facility. As you can know in the reliability analysis, most impressive cause is the malfunctions of pumping operations; especially the common cause failure of two pumps is dominant. In other words, it is possible to assess system-reliability as twice as actual without CCF From these, CCF is extraordinarily important and the results are highly dependent on the CCF factor. And although it would increase with multiple installations, the reliability are not defined as linear with those multiplications. In addition, the differences in results due to the models for analysis are not significant, whereas the various sources of data produce highly different results. Therefore, we conclude that the reliabilities are dependent on the quality of the usable data much better than the variety of models. As a result, the basic and engineering device for the preventions of CCF of the multiple facilities is to design it as reliably as to design the fire-water pump. That is to say, we must assess those reliabilities using PFD whether they are appropriate to SIL (Safety Integrity Level) which is required for the reliability in SIS (Safety Instrumented System). The result of the analysis on the reliability of the fire-water supply with CCF shows that PFD is 3.80E-3, so that it cannot be said to be designed as safely as in the level of SIL5. However, without CCF, PFD is 1.82E-3 which means that they are designed as unsafely as before.

There are currently more than tens of thematic maps in Korea. Among them, there are some thematic maps which are used by one organization only by which was made, and there are common thematic maps which are used by several organizations. In this study, among many kinds of common thematic maps which are currently used, the common thematic maps which will be digitized for parts of NGIS project were chosen and the priority of project was established. After selecting five maps from the common thematic maps classified as the first ranking, current land use map, parcel-address map, administrative boundary map, urban planning map and road map, the area of CheJoo Island was digitized as a pilot project. Through the pilot project of CheJoo Island, the level of application was verified, and the method was presented in order to reduce the trial and error in the process of this production after analyzing the matter from the pilot project. The direction for digitizing common thematic maps was presented based on the result of the pilot project, in addition to, the detail plan was established after deciding the number of people needed, the amount of money spent, and the period needed for making digital maps nationwide.

2016년 경주지진, 2018년 밀양 세종병원 화재사고, 2019년 강원도 동해안 산불, 2020년 코로나바이러스감염증-19 재난까지 매년 다양한 유형의 재난이 발생하면서 재난대응에 대한 관심 역시 커지고 있다. 정부는 물론 각 지자체에서 재난유형별로 재난대응 매뉴얼에 따라 체계적으로 해당 재난에 대한 대응을 실시하고 있으나 중앙 상황실과 현장 간 소통의 어려움, 의사결정의 지연 등으로 인해 신속한 대응방안 수립 및 피해상황 파악에 있어서 미흡한 대처를 보여주어 질타를 받기도 하였다. 본 연구에서는 중앙 상황실과 현장 간의 원활한 소통과 재난으로 발생한 피해현황 및 응급복구 계획 등을 신속하게 수립할 수 있도록 군부대에서 사용하고 있는 공통작전상황도(Common Operating Picture, 이하 COP)의 개념을 재난대응 체계에 도입하여 제시하고자 한다. 공통작전상황도는 미군이 군사적인 대응을 위하여 정보공유 차원에서 처음으로 사용되었으며, 미국연방재난관리청(Federal Emergency Management Agency, 이하 FEMA)이 현재 재난상활 발생 시 의사결정을 지원하기 위한 시스템으로 개발하여 활용하고 있다. 이를 구성하는 요소들은 재난발생시 가장 기초적인 정보(신고사항, 기상정보, 시민제보 등) 뿐 만 아니라 현장에 관한 정보(구체적인 대응상황, 요구사항 등)까지 다루어지고 있으며, 결국 공통작전상황도는 이를 모두 관리할 수 있는 하나의 통합플랫폼이라 할 수 있다. 따라서 본 연구에서는 재난상황에서 공통작전상황도를 활용한 해외사례 분석과 국내 도입 시각 재난유형별로 공통작전상황도에 필요한 정보요소들을 1차적으로 확인함으로써 새로운 재난대응 시스템의 필요함을 강조하고자 한다.

Objectives: Pig farmers are known as the high risk group for the zoonoses, but the study for pig farmers to zoonoses has been rare in Korea. So we surveyed the awareness on zoonoses among pig farmers to suggest directions for education. Methods: We visited four regional spots (Gyeongsangnam-do, Gyeongsangbuk-do, Jeollanam-do, and Chungcheongnam-do) where the self education programs of Korea pork producers were convened. We conducted a questionnaire survey of the general, work-related characteristics and the awareness on zoonoses among 278 pig farmers. Results: The awareness rate of zoonoses itself, brucellosis, tuberculosis and salmonellosis were 52.9%, 85.6%, 87.8%, 89.6%, respectively. The awareness rate of the content related to zoonoses, "Human can be infected by the disease of pig", was 46.9%. Awareness rate of zoonoses tended to increase as the school career, and awareness rate of salmonellosis tended to increase as working duration of pig raising. Conclusions: The pig is the principal reservoir of zoonoses. Therefore, effective working guidelines to prevent zoonoses for pig farmers must be developed and an educational program on zoonoses is needed for pig farmers. Furthermore, publicity activities about the prevention of zoonoses are needed for high-risk groups.

This paper proposes the effective method to improve the protection from induced lightning Surge by making common grounding from individual grounding. Common grounding under equipotential principle is more effective than individual grounding for lightning Surge protection, and so common grounding is indicated as international technical standard under the AC power supply system with neutral line. So, this paper is to propose the effective way of induced lightning Surge protection method for currently installed power supply system which has no neutral grounded line and individual grounding which are weak for lightning Surge protection. This proposal can improve the power supply system as has neutral line, and improve the grounding system to common grounding system. And also this paper proposes to make effective equipotential system with voltage variable shunting devices for lightning Surge protection.

The Elements of common temporary work in Construction Project have ambiguous work scope between client and builder. Also problems of non-breakdown, non-standardization in common temporary work are obstructive when contract. Finally they will be reached claim factors on the construction project. Because the common temporary work information management system is not built, We have to develop common temporary work information management system based on historical cost database for Construction Management. This system will successively accomplish the project in pre-construction step to standardize work items and to forecast the cost of common temporary work. Therefore feasibility study will be possible with historical database in new project.

This paper describes Linear Discriminant Analysis and common vector extraction for speech recognition. Voice signal contains psychological and physiological properties of the speaker as well as dialect differences, acoustical environment effects, and phase differences. For these reasons, the same word spelled out by different speakers can be very different heard. This property of speech signal make it very difficult to extract common properties in the same speech class (word or phoneme). Linear algebra method like BT (Karhunen-Loeve Transformation) is generally used for common properties extraction In the speech signals, but common vector extraction which is suggested by M. Bilginer et at. is used in this paper. The method of M. Bilginer et al. extracts the optimized common vector from the speech signals used for training. And it has 100％ recognition accuracy in the trained data which is used for common vector extraction. In spite of these characteristics, the method has some drawback-we cannot use numbers of speech signal for training and the discriminant information among common vectors is not defined. This paper suggests advanced method which can reduce error rate by maximizing the discriminant information among common vectors. And novel method to normalize the size of common vector also added. The result shows improved performance of algorithm and better recognition accuracy of 2％ than conventional method.
