  • 본 논문에서는 분전반에서의 화재 위험 요소와 화재위험 요소에 대한 현장 실태조사 결과를 분석하였다. 분전반에서의 화재 위험 요소는 크게 전기적 요인, 환경적 요인, 물리적 요인으로 나눌 수 있으며 전기적 요인으로는 단락, 과부하(과전류), 접촉불량, 전류 불평형 등이 있으며 환경적 요인으로는 수분(염분 등), 먼지(분진, 목분, 철분 등), 온도(고온) 등에 의한 절연파괴, 기기 손상, 오동작 등이 있다. 물리적 요인으로는 기계적인 진동이나 충격 등에 의한 전기적 접속부의 이완에 의한 발열 등을 들 수 있다. 이러한 화재 위험 요인에 대하여 현장실태조사를 실시한 결과, 일부 분전반에서 내부에 먼지 등 이물질이 차단기, 전선, 단자대 등의 표면에 부착되어 있음을 확인할 수 있었으며 수분이나 염분 등의 영향으로 전극간 절연물 표면의 열화로 화재가 발생할 가능성이 있다. 또한, 적외선 열화상 분석결과, 일부 차단기 단자에서 국부 발열이 관측되었으며, 부하 분담의 불평형에 의한 발열도 확인되었다. 이러한 위험요인에 의한 화재 예방을 위하여 규정된 전선 굵기의 사용과 적정 체결압력의 확보, 상간 전류 불평형을 줄이기 위한 부하 분담의 조정이 필요하다. 향후, 분전반에서의 전기화재, 감전사고 등 전기재해의 예방을 위하여 지속적이고 체계적인 유지관리는 물론 사고 발생 전에 이상 징후를 사전에 감지하여 조치를 취할 수 있도록 하는 기술의 개발과 현장 적용이 요구된다.

  • Researches on fire resistant performance of primary structural elements such as columns and beams located at above the ground have actively been doing than those located at the below the ground from many researchers. But the structural elements such as columns at underground is very important in aspects of not only structural performance but also fire environment. The columns at the basement carry all the structural loads from the above and that means very critical in fire circumstances than that located at above the grounds. To evaluate the fire resistance performance of primary structural elements located at below the ground we conducted several sorts of surveys that contained fire regulations from several countries and structural types, materials and status of passive fire protection methods.

  • Recently Amore pacific rack-type warehouse fire broke out and argue an urgent improvement of fire protection design code including automatic sprinkler and detection design. Various type of commodities have their unique fire characteristics from fire spread rate and heat lease rate and fire hazard depends on storage height, rack arrangement, aisle width, fire load etc. With increasing ceiling height for more storage space prevent effective water spray of sprinkler head, also delays detection time causes failure of early suppression. To achieve fire protection code performance of this occupancy, Major code articles relating to a classification of commodity, sprinkler system installation, detection and fire fighting are reviewed and suggested based on fire case analysis, code review between country and field survey.

  • The number of dangerous goods are increasing in maritime transport. As a result, a number of nations and international organizations are establishing or amending the rules of dangerous goods. There is necessarily the transport of dangerous goods like fuel and the importance of the definition and scope of the goods is increased. In addition, the responsibility between the parties is different with the notification of the goods and its awareness of transporters. In particular, responsible clauses of the transport rule show antithetical concepts between the scope of immunity and the responsibility of a shipper concerned with wether transporters aware. This research performs two works. First, this research analyzes the definitions and scope of dangerous goods through prior research. Second, this research suggests the necessary of united interpretation of the articles through a comparative analysis on judical decisions concerned with awareness of transporters to dangerous goods. Dangerous goods have a distinctive feature and that is why responsibility and immunity between parties should be differently interpreted with general rules. Parties have duty concerned with faults on general goods and the scope of duty between parties can be specifically made. However, if there is no specific articles concerned with responsibility between parties to dangerous goods, they could confuse the responsibility on duties concerned with risk. Therefore, this research suggests solutions and necessary of the united criteria for the articles to dangerous goods through analyzing precedent cases.

  • The fire compartments which are composed of fire walls and fire doors for buildings are compulsorily required to minimize the fire damage in Korea. The performance standards of fire doors for compartments are regulated by the notification of the ministry of land, transport and maritime affairs and are mainly about the Integrity of the doors not insulation. In this study, we measured the radiant heat of six different kinds of fire doors in fire and analyzed the results and presented the reasons of the need to consider adding the radiant heat standard for fire doors to the notification.

  • Recently, the importance of Research and Development(R&D) security as well as R&D investment is emphasized in the flow of technology hegemony competition, where technology is directly related to national competitiveness.However, despite the enormous impact of the R&D security failure results, research output leakage accidents continue to occur.To solve this problem, this study analyzed leakage accidents and cases of R&D output and concluded that it is priory to develop regulations to raise security awareness at the field researcher level rather than the macroscopic security management system. In addition, in order to design the direction of the researcher security measures, observational study was conducted at the university research site, and four directions were presented, including case analysis and integration. The direction for designing researcher security measures will be used as a basis for developing security regulations specialized in future research sites and security management systems for research institutes.

  • Soon after September 11 attacks in 2001, there were strong demands in Korea on making relevant laws and regulations on aviation security, and Korean parliament legislated "Aviation Safety and Security Act"to fulfill the demands on safety and security of aircrafts during aviation. However, the current Aviation Safety and Security Act seems to have many problems which do not meet the practical needs in Korea, because there were not enough considerations on the practical needs and extinguishable national circumstances on civil aviation system in Korea, but only regarded the relevant international conventions and foreign practices on it. In this context, it is necessary to amend several provisions in Aviation Safety and Security Act to enhance more practical efficiencies in its implementation through systematization of the provisions on crimes which may happen during aviation. In this context, this article argues two main issues. First, Article 39 of Aviation Safety and Security Act does not express whether it is possible to punish the attempt of crime of causing damage to aircraft. Therefore, regarding a principle of legality, it is impossible to punish the perpetrator even when coincidently failed to destruct or damage aircraft. In this context, this article argues that the necessity to introduce the possibility to punish the attempt of crime of causing damage to aircraft. Second, regarding Article 160 of Civil Aviation Act of Korea, current Aviation Safety and Security Act should be amended by guaranteeing the culpability of negligence of crime of causing damage to aircraft.

  • The purpose of this study is to improve the level of records management by enhancing the risk management in university archives. Through surveys and post-interviews, the current status of risk management in university archives was investigated, the results of the investigation were analyzed to identify problems and limitations in risk management in university archives, and the following suggestions for improvements were made. First, the legal effects of risk management should be strengthened in the Public Records Management Act, and matters related to risk management should be stipulated. Second, the National Archives of Korea should actively intervene to identify problems in risk management in university archives and provide appropriate support for problem-solving. Third, the identity of university archives as independent organizations should be secured for the implementation of professional and active records management tasks. Fourth, standards and manuals reflecting risk management practices for university archives should be prepared. Fifth, a sufficient budget must be secured to meet all necessary requirements for risk management. Lastly, cooperation in the performance of records management and risk management tasks should be achieved by raising awareness of university archives and their records management tasks among the heads of the institutions and members of the organizations.
