Trade specialization index, import market share, unit value index, market comparative advantage index have been applied to compare the competitiveness of forest products in Korean and European markets for the case of Korea-EU FTA. The results say that no items of non-timber products would show a surge of imports as a result of FTA. Timber products, however, such as non-coniferous plywood, continuously shaped wood (non-coniferous), densified wood, wood wool and flour, other (plywood), other (particle board, 441039)), other (fiberboard), oriented strand board (other), other (particle board, 441090), other (particle board, 441031), Prefabricated buildings of wood, fibreboard (of a density exceeding $0.5g/cm^3$ but not exceeding $0.8g/cm^3$), wooden frames (for paintings, photographs, mirrors or similar objects) and wood marquetry and inlaid wood are expected to increase of their imports by eliminating tariffs. For Korean exports no items of non-timber products have competitiveness in European market. For Korean pyroligneous liquid, which is the only competitive timber product in EU market in terms of MCA and TSI, it is difficult to decide whether it has competitiveness, since the actual exports have taken place occasionally during a period of last five years.

The purpose of this study was to review the agreement and disagreement logics on privatization of health care to bring quality enhancement of medical service and alienated area without medical services at the same time, to identify the core keywords through language network analysis a kind of contents analysis on the editorials dealing with privatization of health care and hospitals for profit published on the major daily newspapers for the recent three years, and to find out what is the core of the controversy through the connection centrality analysis of core keywords. Conclusively, it was found from the centrality analysis that "medical service," "hospital," "privatization," "privatization of health care," "hospital for profit" and "Government" were situated in the center of the controversy. It is natural that keywords such as "medical service," "hospital," "privatization," "privatization of health care"and "hospital for profit" were located in the center because this study reviewed the editorials published on major newspapers for the recent three years regarding the privatization of health care or hospital for profit. Next important keywords (words) were "people," "health"and "health insurance." It shows that privatization of health care was not simply seen as the opening of medical service market but as an important issue related to health of people and health Insurance. Next words with high centrality were "objection" and "allowance." Through the contents analysis of editorials for the last three years, it was found that the opinions for and against the privatization were equally matched according to the centrality analysis result. On the other hand, there is one noticeable result in centrality analysis, which is the keywords such as "US," "Korea US" and "FTA" showed centrality to some extent. It shows privatization is handled relating US and Korea US FTA by editorials.

샌디에이고 국제 광학 및 포토닉스 박람회(SPIE Optics + Photonics)가 지난 8월 12일부터 16일까지 남부 캘리포니아의 아름다운 항구도시 샌디에이고(San Diego)에서 개최됐다. 한미자유무역협정(FTA)이 발효되었는데도 단 하나의 국내 기업만이 전시장에 출품하는 실정이다. 따라서 협회는 회원사들의 미국 진출을 지원할 수 있는 신규 사업을 조속히 시작할 필요가 있다. 최근 삼성과 애플의 미국 특허소송에서 삼성전자가 완패해 천문학적인 배상금을 지불해야 한다는 충격적인 뉴스가 전해졌다. 이로 인해 애플사는 미국 주식 역사상 가장 비싼 시가총액 세계 1위 기업으로 등극했다. 창의력이 중요한 이 시대에 아직도 국내 산업, 경제, 정치가 1980년대를 주름잡았던 무조건 밀어붙이면 된다는 식의 '쌍팔년도 사고(思考)'에서 벗어나지 못하고 특허전쟁에서 완패당했다고 생각하면 안타까운 심정을 금할 수 없다. 이번 삼성과 애플의 특허전쟁이 국내 제조업계가 창조적으로 환골탈태하는 계기가 될 수 있을 것이다. 국내 광학업체들이 일본, 대만, 중국 등과의 치열한 경쟁으로 정신없이 바쁘더라도 해외 전람회에 창조적이고 감성적인 신제품을 출품해야 세계 최고의 글로벌 기업으로 도약할 수 있을 것이라고 생각한다.

In this paper, we suggest the criticality of Hidden Failure with regard to the design of watch dog timer, used to detect HALT on railway signaling embedded controller, via FMEA and FTA. Hidden Failure means reliability and safety degradation of the system due to any failure occurred on elements added for fault tolerance. In this paper, therefore, we design vital watch dog timer to prevent the system from operating in low SIL conditions and assess the safety of circuit on failure occurrence to demonstrate that safety degradation problems owing to existing design are supplemented.

This study is about the quantitative safety assessment of hydrogen station in Korea operating with on-site type. This was written by background information that before qualitative safety assessment to write. For the qualitative safety assessment method, the study used FMEA(failure mode & effect analysis) and HAZOP(hazard & operability), and adopted the FTA(fault tree analysis) as the quantitative safety assessment method. To write the FTA, we wrote FT by Top event that hydrogen leakage can be called most serious accident of hydrogen station. Each base event collect reliability data by reliability data handbook, THERP-HRA and estimation of the engineering. Assessment looked at the high frequency and the possible risk through Gate, Importance, m.cutsets analysis.

Process safety technology has developed from qualitative methods such as HAZOP (hazard and operability study) to semi-quantitative methods such as LOPA (layer of protection analysis), and quantitative methods are actively studied these days. Quantitative risk assessment (QRA) is often based on fault tree analysis (FTA). FTA is efficient, but difficult to apply when failure events are not independent of each other. This problem can be avoided using a Markov process (MP). MP requires definition of all possible states, and thus, generally, is more complicated than FTA. A method is proposed in this work that uses an MP model and a Weibull distribution model in order to construct a reliability model for multiple dependent failures. As a case study, a pressure safety valve (PSV) is considered, for which there are three kinds of failure, i.e. open failure, close failure, and gas tight failure. According to recently reported inspection results, open failure and close failure are dependent on each other. A reliability model for a PSV group is proposed in this work that is to reproduce these results. It is expected that the application of the proposed method can be expanded to QRA of various systems that have partially dependent multiple failure states.

The Farm-Closure Assistance (FCA) program is operated to compensate for lost farm income, to stabilize the management of low-competitive farms, and to enhance competitiveness of target items. The FCA, however, has several problems, such as the balloon effect and fraudulent receipts. Therefore, it is important to examine the operational problems of the FCA, establish improvement plans, and settle the measures. The objectives of this study are to analyze problems and suggest solutions for FCA, reflecting the viewpoints of local government officials who are in charge of actual tasks on the FCA front lines. The study analyzes whether characteristics of government officials lead to differences in setting the maximum amounts and extensions to FCA. Factors influencing the necessity of setting ceilings on FCA were work experience, recognition of agriculture's importance, and the FTA's impact on domestic agriculture, gender, and regions. Factors affecting the extension of FCA were the agency unit, work experience on the FTA, recognition of the effects of FTA direct payments and FCA, and recognition of the subsidy's direction. The results can be employed as a fundamental background that can set the direction for institutional improvement when the government tries to improve FCA.

A precedent defense project study was carried out in the early stage of the project to support efficient determination of the acquisition method of the determined weapons system. A precedent study in the early stage of the project has been neglected, but lack of performance and increased costs are continuing problems. In a precedent study on a number of items within a limited time frame, expected risks during project implementation were not identified and reduced by failing to review the key review element in depth. Therefore, in this paper, we studied the application of the FTA/FMEA technique used in the system safety analysis process to identify key factors to be considered when carrying out the defense research project. The methodology for the development of the key review items was established through the improvement of the FTA/FMEA technique in order to meet specific conditions and given conditions. Based on the results of this study, we redefined core key factors in the precedent study stage, thereby eliminating unnecessary and anticipated risks that may arise in the future project management aspects of the defense project. It is anticipated that this will reduce costs and time in terms of the lifecycle of the weapon system and promote stable operation of the project through reduction of risk.

The International Maritime Organization (IMO) is promoting the introduction of e-Navigation that prevents maritime accidents by fusion of Information & Communication Technology (ICT) with ship operation technology. In Korea, Korean e-Navigation is also being developed for fishing vessels and small vessels sailing offshore, which are vulnerable to maritime accidents. However, for the successful development of Korean e-Navigation, it is necessary to develop an indicator that can evaluate the development performance so that the development performance that has been progressed so far can be evaluated and the development direction can be re-established. Therefore, this study attempted to develop an evaluation index tailored to the development goal of e-Navigation service centering on the collision accident, which is a major maritime accident. In this study, a collision accident evaluation index for e-Navigation service was developed by deriving and quantifying the root cause of maritime collision accidents using Root cause analysis(RCA) and fault tree analysis (FTA) techniques. This indicator is considered to be helpful in reducing maritime accidents as it is used as a development indicator for e-Navigation and an indicator for maritime collision accident analysis.
