The National Fire Safety Code (NFSC) sets forth the installation methods and technical standards of firefighting facilities. This information is stipulated in the attached Table 1 of the Enforcement Decree of the Act on Fire Prevention and Installation, Maintenance and Safety Control of Fire-Fighting Systems. The NFSC serves as a foundation for fire prevention and public safety. However, the current version of the NFSC has been under scrutiny due to its delayed enactment and revision process. This is because of its structural inflexibility, time-consuming procedures, and mixed usage of both performance and technical standards. Furthermore, there are difficulties with keeping its unique specialties due to the absence of a specialized, permanent independent entity that enacts, revises, and maintains its standards. Moreover, the NFSC lacks collectivity, openness, and consistency. Therefore, to overcome the aforementioned obstacles, this study investigates the operational and legal status of the NFSC and the problems regarding its enactment and revision process. Further, it presents suggestions for system improvement by analyzing and comparing the information with domestic and foreign counterparts dedicated to managing their similar technical NFSC standards. First, the study recommends that the legal performance and technical standards mixed within the current NFSC should be separated. Second, the enactment and revision of technical standards should be implemented by the private sector and not by the government. Third, technical standards should adopt a user-oriented approach for the code system.

The Ministry of Environment of the Republic of Korea set up 'the $2^{nd}$ Fundamental Plan for Wetlands Conservation' to facilitate systematic surveys and management of various national wetlands and to promote sustainable conservation and use of those wetlands. The mid-term fundamental plan was established in accordance with the Article 5 of the Wetland Conservation Act, which spans 5 years from 2013 to 2017 and covers national wetlands including inland wetlands and coastal wetlands stated in the Act. The fundamental plan aims to promote the wise use of wetlands through establishing policies for sustainable conservation based on the assessment of implementation of the $1^{st}$ Fundamental Plan, setting up a scientific framework for establishment and implementation of national wetland policies by improving wetland survey systems and enhancing basis wetland data, improving the ecological health of wetlands and securing biodiversity conservation of wetlands by strengthening conservation and management system of national wetlands, and through raising public awareness and diversify education and promotion tools. The main objectives of the $2^{nd}$ Fundamental Plan is to revise the entire Wetland Conservation Act, to create a new monitoring system of national inland wetlands, to upgrade the national wetlands inventory, to reflect the 'Ecological Map' for promoting precautionary management of wetlands, to improve the 'Wetland Restoration and Management' system to build wetlands resilience, and to systematize the wise use of wetlands that benefits local people. As the Ministry of Environment plans to establish its other master plan for wetland conservation based on the $2^{nd}$ Fundamental Plan, this document introduces the $2^{nd}$ Fundamental Plan to stakeholder and wetland professions.

This study looks at plans for the efficient functions of the current terror response system in Korea. The results are derived from by comparing and analyzing American, British, German, Japanese, and Korean terror response systems. It focuses especially on addressing some problems with Korea's terror response system and how to operate it effectively. The study will systematically compare and analyze each nation's terror countermeasure studying organizational, functional, and legal aspects as standards. This study shows that there is not an exclusive terror response center in Korea compared with other nations such as America, the United Kingdom, Germany, and Japan. Also it is difficult to expect effective and vigorous operations due to weak cooperation across the relevant organizations. The presidential directive of the state's anti-terrorism action guidelines is legally ineffective. This means that on legal grounds, it is difficult to take actions to prevent the terrorism. Therefore, keys to counteracting terrorism derived from this study are summarized below. In the first place, an integrated terror response system should be set up for expansion of information sharing which leads to emergence effect. In the second place, the superior legislative systems should be made for the cleardefinition and extent of what the terror is, rigid enforcement of investigation, immigration, and keeping an eye on the funds raised by terrorists and tracking down the terrorists, the plan for eco-terrorism. In the third place, to augment security of vital facilities and peoples' awareness of terrorism safety should be emphasized and a cooperative system between civil and government organizations need to be built. In the fourth place, system for crisis management must be provided in an effort to maximize management system of terrorism and unify a decentralized emergency countermeasures effectively.

In order to estimate production cost of rice per ha of large farm, a detail survey of 104ha farm was made in 1994. Amount of labor input and labor cost per ha was calculated as 270, 000won and 108hours. Direct production cost of the farm was 1, 092, 000won(l00) and was lower than that of average farms 2, 067, 000won(189) in Korea. But it still was higher than that of Sac1amento farms 717, 000won(66) and that of Buter Area's, 845, 000won(77). It seems feasible to cut down the cost about 10~15% provided the labor and machinery may be used more efficiently. Some cost down may also be possible on marketing and processing sectors. Therefore it may not be pessimistic in competing with U.S. rice farms if we establish 100ha size well managed and arranged farms in Korea.

The need for education and training on engine-part maintenance is rising in order to prevent marine accidents occurring due to a surge in engine-part damages. However, practical training using actual equipment is difficult due to the size and location of the equipment. Therefore, the necessity of developing a training system for marine engines using virtual reality (VR) is intensifying. The purpose of this paper is to develop an optimized system for marine engine education and training using existing VR programs and equipment. To this end, we selected and modeled the marine engine and education target suitable for the class, and developed the system using VR development software. The developed VR education and training system is designed to experience content that is otherwise difficult to train or practice in the curriculum through virtual reality. In fact, fourth grade students from Maritime University were taught using marine engine VR educational equipment, and it confirmed that there was an educational effect on the class. In the future, the introduction of an education and training system using VR in the field of marine engines can improve their maintenance and repairing capacity, and aid in reducing marine accidents.need for education and training on engine part maintenance is increasing to prevent marine accidents.

From the beginning of the construction stage, the fire protection regulation for the nuclear power plants conforms to the design requirements for the acquisition of the license permit. This regulation is based on the plant status of the normal operation, but it is not enough to be used as an application standard for fire protection at the transient mode of the plant and the outage time for refueling as well as for the plant decommissioning. While the advanced fire protection requirement that has been developed in America recently suggests the performance-based requirement and management rule applicable to the overall life time of the plant, it simply represents the conceptual application. It means that it can not be treated as appropriate standards because it does not deal with the qualitative and quantitative approach in specific ways. By the way, with the use of the performance-based fire risk analysis, the dynamic behavior of the heat and smoke at the fire compartment of the nuclear power plants can be analyzed and the thermal effect to the safety-related equipment and cables can be evaluated as well. At this paper, it suggests the ways to change the applicable fire protection regulations and the required evaluation items for the fire risk resulted from the plant configuration change with an intent to introduce the state-of-the-art quantitative fire risk analysis technology at the domestic nuclear power plants.

Recent domestic use of radiations has increased in the number of institutions and companies as well as operating as an investment, a variety of facilities and safety management are becoming increasingly complex. Despite the increase of radiation workers and facilities, the number of RSOs (Radiation Safety Officers) has not increased with a growing domestic radiation industry. The radiation safety management work (radiation workers management, radiation sources management, facilities management etc.) has been managed by insufficient number of the RSOs. These problems could be directly or indirectly related to causes of the radiation accidents. In this paper, we designed the Process Mapping of radiation safety management work for an efficient safety management of the radiation facilities and protection of radiation accidents. To develop the Process Mapping, we analyzed the radiation safety requirements of management issues and the individual procedures. Based on the Process Mapping, the work procedures for an appropriate radiation safety management of each institution can be configured clearly. Through this procedures, the safety risk factors in radiation facilities can be reduced, and the radiation safety management system will be improved. Depending on your needs, the Process Mapping could be modified and could be used for an efficient radiation safety management.

우리나라는 홍수조절이나 통제를 목적으로 10개의 다목적댐을 통한 홍수방재시스템을 운영하고 있다. 다목적댐 또한 방류능력과 저류능력에 한계가 있기 때문에 안정적인 홍수조절을 위해서는 유입량과 유출량을 미리 예측할 수 있어야 한다. 하지만, 강수량은 그 변동이 심하여 정확한 예측이 어렵기 때문에 합리적인 하천 구조물의 설계와 홍수예측기술의 발전을 위해서는 강우-유출 해석뿐만 아니라 과거의 수문자료를 사용한 통계적인 분석이 요구된다. 최근 기후변화로 인해 과거에 겪지 않았던 이상 기후현상이 빈번하게 나타나고 있다. 기상청발표에 따르면 최근 10년간(1996~2005) 15개 지점의 평균 연강수량은 1,458.7 m로 약 10 �時貂� 하였고, 특히 여름철은 18 %로 증가폭이 가장 크며 호우일수는 30년 평균이 2일인데 비하여 2.8일로 0.8일 증가하였다. 이러한 강수량 및 호우일수 증가는 여름철 심각한 수해를 초래할 수 있다. 본 연구는 기후변화로 인한 수해를 대비하여 홍수기중 저수지 제한수위운영의 안정성을 검토하였다. 연구 대상 지역은 광교저수지로 수원천 상류부인 경기도 수원시 장안구 연무동에 위치한다. 유역면적은 10.98 km, 유효저수량은 250.0 만$m3$이며, 현재 예비취수원으로 사용되고 있다. 기후변화에 따른 하류지역의 예상치 못한 홍수피해를 사전에 예방하기 위해 광교저수지 유역의 설계 강수량과 설계 홍수량을 산정하였다. 제한수위의 시나리오는 현재 시행중인 제한수위와 만수위를 포함하여 5개로 설정하였다. 설계 홍수량이 광교저수지로 유입될 때 시나리오에 따른 월류량은 웨어공식을 이용하여 산정하였으며 결론은 다음과 같다. 1. 39년간의 최다 일 강수량 자료를 사용하여 100년 빈도의 설계 강수량을 Gumbel 분포법으로 산정한 결과 344.4 mm임을 알 수 있었다. 2. 광교저수지 유역의 설계 홍수량을 SCS 방법을 이용하여 산정한 결과 $216.2\;m^3/s$/s로 나타났으며, 총 유입량은 $301.0\;m^3$/day로 파악되었다. 3. 광교저수지로 설계홍수량이 유입될 때 제한수위 시나리오에 따른 최대 방류량은 EL. 87 m의 경우 $23.1\;m^3/s$, EL. 89 m의 경우$27.5\;m^3/s$ EL. 91.36 m의 경우 $79.6\;m^3/s$, EL. 93 m의 경우 $121.1\;m^3/s$ EL. 95.2 m의 경우 $137.`\;m^3/s$이다. 광교저수지 하류부분의 하천정비기본계획상의 설계 홍수량은 $114\;m^3/s$로 홍수기중 저수지의 제한수위는 EL. 91.36 m이하로 설정하는 것이 바람직한 것으로 판단된다.
