1988년 이전에는 한국의 석유화학공장은 다른 나라에 비하여 관리상태나 손해상황이 양호한 공 장으로 여겨져 거의 안전도조사(underwriting survey)가 실시되지 않았으나 1989년 이후부터 보험사고가 급격히 증가, 보험금 지급이 많아져 위험조사를 실시한 후 보험을 인수하게 되었다. 일반적으로 석유화학공업의 내용연수는 15년에서 20년으로 보고 있으며 미국, 일본 등 선진국 에서도 건설한지 20년을 전후해서 사고가 다발한다는 점은 국내 석유화학공장의 안전성 확보대 책에서 중요한 점을 시사한다. 석유화학공업의 안전성 확보대책으로서 해외재보험자가 요구하고 있는 "경영전반적인 위험관리"를 도입 추진하여야 할 것으로 사료된다. 여기에는 사전적 손해 방지대책을 포함하는 위험통제는 기본적으로 이루어져야 하며 사후적 대책인 위험재무도 경영 효율이 극대화되도록 하여야 한다. 그러나 최근 들어 국내공장의 사고빈발로 해외재보험자들이 재물손해의 자기부담금액(deductible)인상(business interuption)의 Time Excess연장(7일에서3 0일) 등의 보험조건을 강화하고 있다. 따라서 외국의 사고 경험에 비추어 국내 플랜트의 내용연 수가 거의 다 되어서 사고발생위험이 잠재하고 있고 석유화학공업의 특성상 사고빈도는 낮으나 손해규모가 대규모이고 국가경제에 기여하는 비율이 타산업에 비해 월등히 크다는 점 등에서 안전대책에 대한 경영자의 관심제고를 밑바탕으로 한 위험관리의 정착화, 안전기준 등의 국제 수준으로 향상 및 전문기술인력 확보를 통하여 사고발생 억제에 대하여 소홀히 해서는 안된다고 사료된다.안된다고 사료된다.작 원리 및 제조방법에 대하여 기술한다. 2차원 그래픽의 기능만으로도 충분한 역할을 수행할 수 있지만, 그 다음 단계인 기본설계나 상세설계와의 자료 공유를 생각하면, 3차원 그래 픽이 필요하다. 다만, 3차원 그래픽 기능을 추가하기 위해 많은 노력이 요구되는데, 현재 PHIG S와 x-window가 결합되어 PEX라는 라이브러리로 개발되고 있으므로 차후의 연구에 포함될 수 있을 것이며, 이 글에서는 간단한 2차원 그래픽 기능만을 이용하였다. 앞으로 PEX의 기능을 적 절히 구사하면, 좋은 효과를 볼 수 있을 것이다. 279cm 되게 하고 선축은 팬톰의 27번 절편과 28번 절편의 접변과 최대 전단면의 교차선과 일치시켜 양방향에서 15분씩 조사하여 전단면에서 선량을 측정하였다. 팬톰내 선축상 중앙점의 선량을 기준으로 다른 부위의 선량을 비교하였다. 두경부와 복부, 폐의 하반에서 선량의 차이는 $\pm$ 10% 이내였고, 폐의 상반과 어깨와 골반 부위에서 선량은 10%이상 저선량을 보였다. 특히 어깨부위에는 30%이상 저선량을 보였다. 이로부터 서울대병원과 유사한 조건에서 코발트로 전신조사하는 경우에는 폐나 두경부에 대응하는 조직보상체를 이용하기보다는 어깨부위에 선량을 추가하는 것이 바람직할 것이라고 생각한다.alpha$ 부분공간들의 합공간 역시 on-semistrbtifiable over $\alpha$ 하다. 6. 폐연속 net-cevering 함수에 의하여 cn-semistratifiable over $\alpha$ 성질이 보존된다. 보잘것이 없었고, 현재에도

Because of Recent intensive rainfall, nationally landslides and slope failure phenomenon has been frequently occur. Providing proposed-measures to the natural disasters that occur in these localities and the slope, must be derived ground of strength parameters(shear strength) as a design input data. However, it is such as extra deforestation and a lot of economic costs in order to make the access to the current area and the slopes ground survey is required. Thus, by small dynamic cone penetration test machine using the human to carry in the field, it is possible to easily measure the characteristics and strength constant of the ground of more than one region. In this study through researching analysis of the domestic and foreign small dynamic cone penetration test method, it has proposed a cone material and test methods suitable for the country. Cone penetration test Nc in the field has comparated with analysis of the value and the standard penetration test N value. And, in addition to this, direct shear test and borehole shear test were performed by depth, bedrock, and soil type and passing #200 and the correlation of the Nc value. In particular, in the present study, for the sandy soil that has distict distribute in mountain, it is proposed relation of shear strength corresponding to the Nc value (cohesion and internal friction angle) in order to calculate such effective ground shear strength.

Companies that have suffered serious labor shortages are relocating their factories abroad where they can solve this problem by increasing the employment of foreign workers. Construction sites also employ foreign workers to supplement the scarce manpower, and the demand for foreign workers has been gradually increasing over time. Recently, based on discussions on whether or not to introduce foreign workers, the policy on the input of foreign workers into domestic construction sites has been shifted to exploring the actual input conditions and efficient management methods. In this study, we investigated the current status and input situation of foreign workers at the construction sites of the target area, analyzed the problems they posed from the manager's viewpoint, and derived a method of improving the utilization of foreign workers at construction sites. In order to proceed with this study, we surveyed the actual situation of the construction sites, which consisted mainly of foreign workers and domestic workers (managers), by investigating the construction sites, and conducted 1: 1 interviews to ensure the reliability of the survey. The data obtained from the survey were analyzed using the SPSS analysis program, and the response rate was analyzed for each item. As a result, various problems, such as institutional problems, communication problems, and quality deterioration due to malfunction, appeared. Therefore, this study derives an improvement plan for the efficient utilization of foreign workers by improving the institutional level related to their language education, wages and employment.

As of April 2006, Korea had successfully invited twelve global IT R&D centers to help implement the u-IT839 strategy, but there have also been some worries about their research and collaboration performance in Korea. Although it is too early to judge the invitation outcome only after two years or less of their working, the Korean government is being advised to employ a more customized invitation strategy. In this paper, an analytic framework for the attraction of global R&D centers is developed based on the attractiveness-competitiveness matrix, and is applied empirically to the IT industry. Fourteen major IT technology categories and their sub-technological areas are classified into four strategic groups (priority group, wish group, consideration group, and hold group) along the framework via expert surveys and the Analytic Hierarchy Process (AHP) technique. This study is expected to help the government to implement the 'select and focus' strategy in inviting global R&D centers and creating synergy effects between them by providing basic data on global R&D partnership priorities. The implications and limitations of the research and future research directions are discussed at the final section.

Countries across the globe, including those in Europe, are waging a "war against terrorism" as international terrorist groups such as ISIS and lone-wolf terrorists have unleashed various large-scale attacks on rail infrastructure. Anti-South Korean sentiment exists in Muslim-majority countries because the nation has cooperated with the US for its military interventions in the Middle East, and ISIS has threatened to target South Korea four times since September 9, 2015. In addition, North Korea has been left isolated in the international community with its missile and nuclear tests, while further escalating inter-Korean tension and threatening to strike major facilities and attack important figures in the South. These situations imply that South Korea is no longer immune to terrorist attacks. If the nation fails to prevent or deter such terrorist attacks against rail networks, massive casualties, property damage and social confusion would be unavoidable, deteriorating national and international trust in its counter-terrorism policies. This may lead to a national crisis involving decreases in the number of tourists, dampened interest of foreign investors, and capital flight. This study aims to propose policy measures to enhance railroad security checks, based on the work of railroad police officers, for the sake of protecting citizens and public safety. The suggestions include an incremental expansion of railroad security checks; growth of the railroad police force and adjustment of their policing distribution with other police officers; enhancement of security systems across important rail networks; improvement of the Railroad Safety Act; Southeast Asia, including the corresponding strengthening of the national crackdown illegal immigrants, and plans for pre-emptive and regular cooperation among organizations related to the promotion of security checks and the prevention of terrorist attacks.

As radiation therapy is one of three major cancer treatment methods, many cancer patients get radiation therapy. Because of the invisible and scattering characteristics of radiation, it is impossible to identify the quality and the amount of radiation and secondary cancer could be induced by scattered radiation. Because of advanced technique of radiation therapy and the reasons mentioned above, quality assurance of radiotherapy machine should be performed completely. International organizations such as International Atomic Energy Agency (IAEA), American Association of Physicists in Medicine (AAPM) suggest report of quality assurance to recommend united method of radiotherapy machine quality assurance. Domestic society of medical physics, however, is too small to make such a report, domestic hospitals selectively choose some of contents in global suggestions. As there are no suggestions for domestic hospitals and global suggestions are being updated, we did a survey about quality assurance for radiotherapy machine. The questionnaire is composed of possession of radiotherapy machine, items performed for quality assurance and manpower, etc. 37 of 72 hospitals answered to survey. These results could be used for making domestic standard quality assurance procedure.

As a professional occupation, landscape education focuses on fostering professional human resources and is one of the major axes of the landscape industry. In this study, a survey of landscape students on their learning and pedagogics was conducted with the aim to present basic information for the improvement of teaching on landscape construction. A total of 348 people answered 14 questions in the category of the impression of landscape construction classes included in the questionnaire. The results showed that the students found landscape construction classes academically important and recognized the necessity for completing these classes, but they were not satisfied with the learning environments and pedagogics used in these classes. They found what they learned not readily applicable to actual practice and saw these classes as part of their preparations for the landscape engineer qualification test. Their demands in relation to the classes included field practice-oriented teaching and participation in various programs for field practice, which highlights the necessity for human resource management-oriented classes that cover planning, design, construction, and management. Challenges in relation to field practice included the provision of environment, for example offering a variety of opportunities and improving treatment in practice. This study has significance in that it analyzed the views of students and discussed directions for future improvement since there is a lack of studies and discussions about education in the field of landscape construction. This study also has a limitation that only four-year universities were included in the study. Comprehensive studies including investigating junior college and graduate school curricula and case studies of landscape construction curricula overseas are needed in the future.

The technical expert standing system of our const겨ction industry is operated by the Ministry of Labor subjective national technical qualification law, as the professional engineer, architect and architect-engineer and so on. The construction management(CM) which is introduced on middle 1990 activates a building industry the condition of the essential indispensability for is becoming, is not officially recognized with national qualification to be, that as pending issue it is most urgent, the specialty manpower positivity which is judged as the nostril poop]e for qualification of the civil CM educational institutions has the certification which is a each educational program and a separate way and it is the actual condition which is become accomplished. The problem when as international certification the CMAA which is only it secures a reliability certification which is a CCM and SAVE seeing in the certified which is a CVS, compares in the foreign nation and the CM certification is excessive, it does not secure a reliability and an efficient characteristic to give a confusion to the capital increase lattices which in a condition are, it is mass produced it is a point. It saw from, it observes the capital increase reserve problem point which is a domestic CM and the certification integration which is a report and system anger it leads and with national certified qualification it develops to present the improvement program for, it does to sleep.

Korea has disposed of medium and low level radioactive waste generated by operating nuclear power plants permanently through the radioactive waste repository located in Gyeongju. However, the maritime transport of radioactive waste is exposed to the risk of marine accidents, and it will be necessary to introduce a system to secure safety from the viewpoint of the function and role of the Korea Coast Guard. Especially, Korea is affected by large-scale marine accidents, such as the Hebei Spirit or Sewol accidents. From this point of view, we analyzed the current status of Korea radioactive waste shipping and examined the response systems of major foreign countries. As a result of examining major cases of accidents, we have operated an Emergency Towing Vessel (ETV) fleet centering on European countries in order to respond urgently to marine casualties that may have social, regional and international effects, such as accidents of similar nuclear material carriers and dangerous cargo ships. It proves a partial effect. Based on this, we propose the introduction of the Korean ETV System. In other words, it is necessary to respond to large-scale marine accidents that could lead to enormous environmental, property, and personal damage, such as marine accidents involving nuclear material ships, large oil tankers, and large passenger ships. For this, it seems necessary to introduce Korea ETV, which can carry out emergency towing, oil pollution control function, large - scale rescue equipment and manpower. This will lead to the enhancement of the Korea Coast Guard response to marine accidents, and will not miss the golden time of the initial response to the national disaster, which will help protect precious people, property and the environment.
