Purpose: By measuring and evaluating the risk of biodiesel through non-volatile residue (NVR) and flash point and explosion limit measurement at a specific temperature according to ASTM test standards, the risk of chemical fire causative substances is identified and a universal evaluation method By derivation and securing the risk-related data of the material, it can be used for the identification and analysis of the cause of the fire, and it can be applied to the risk assessment of other chemical substances Method: In order to measure the risk of biodiesel, it was measured using the non-volatile residue(NVR) measurement method, which measures how much flammable liquid is generated at a specific temperature. Heating was tested by applying KS M 5000: 2009 Test Method 4111. In addition, the flash point was measured using the method specified in ASTM E659-782005, and the energy supply method was measured using the constant temperature method. In addition, the explosion limit measurement was conducted in accordance with ASTM E 681-04 「Standard test method for concentration limits of flammability of chemicals(Vapors and gases)」 test standard. Result: As a result of checking the amount of combustible liquid by the non-volatile residue (NVR)measurement method, the non-volatile residue(NVR) of general diesel when left at 105±2℃ for 3 hours was about 30% (70% of volatile matter) and about 4% of biodiesel. In addition, similar results were obtained for the non-volatile residue(NVR)heating temperature of 150±2℃, 3 hours and 200±2℃ for 1 hour, and white smoke was generated at 200℃ or higher. In addition, similar values were obtained as a result of experimentally checking the explosion (combustion) limits of general diesel, general diesel containing 20% biodiesel, and 100% biodiesel. Therefore, it was confirmed that the flammability risk did not significantly affect the explosion risk. Conclusion: The results of this study suggested the risk judgment criteria for mixtures through experimental research on flammable mixtures for the purpose of securing the effectiveness, reliability, and reproducibility of the details of the criteria for determining dangerous substances in the existing Dangerous Materials Safety Management Act. It will be possible to provide reference data for the judgment criteria for flammable liquids that are regulated in the field. In addition, if the know-how for each test method is accumulated through this study, it is expected that it will be used as basic data in the research on risk assessment of dangerous substances and as a basis for research on the determination of dangerous substances.

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.

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.

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.
