  • Through this study, a conceptual design for the next generation high-speed EMU has been derived to meet the crash worthiness requirements of the Korean rollingstock safety regulation. The crashworthiness regulations require some performance requirements for two heavy collision accident scenarios; a train-to-train collision at the relative speed of 36 km/h, and a collision against a standard deformable obstacle of 15 ton at 110km/h. The complete train set will be composed of 2TC-6M with 13 ton axle load, which is different from KTX with the power car of 17 ton axle load. Using theoretical and numerical analyses, a crashworthy conceptual design was derived in terms of mean crush forces and energy absorptions for principal crushable structures and devices. The derived conceptual design was evaluated and improved using one dimensional dynamic simulations for the bar-spring-damper-mass model. It is shown from the simulation results that the suggested conceptual design can easily satisfy domestic crashworthiness requirements.

  • The obstacle deflector sweeps obstacles off the track or absorbs crash energy with an energy absorber to prevent derailment of a train and to minimize damage and casualties after an accident. In this study, an obstacle deflector and its operational mechanism were designed with a tension-type energy absorber and a 4-bar linkage system. Also, a test method was suggested and verified with FEA (Finite Element Analysis) and UTM (Universal Test Machine) for testing of the static load and energy absorbing ability according to EN 15227 regulations. Through this study, an obstacle deflector that meets the EN 15227 standard was designed and a test method was suggested to adjust the collapse load easily and to verify it experimentally according to the design and verification procedure of the obstacle deflector.

  • Recently the consideration for occupants' security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic Laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulations. Therefore when big fire occurs, it is not enough to guarantee for occupants to escape safely. Specially since domestic escape relevant laws are divided into Architect relevant law and fire fighting relevant law, it has caused to bring various problems. So This study will show the problems of the evacuation regulation which is registrated in the Architect relevant law and fire fighting relevant law. And also later, when Architect escape relevant laws re-registrate, this study will be used as foundational materials.

  • In complex buildings, Way-finding is the most important factor for safe evacuation. Recently, evacuation guidance systems using smartphones have been developed. However, smartphone evacuation guidance maps used in these studies appear different from those used in previous studies due to the lack of established standards. Therefore, in this study, we conducted a preference survey of evacuation guidance maps as a basic research for establishing evacuation guidance maps using smartphones. The components of smartphone evacuation guidance maps were selected using regulations and analyses conducted in previous studies, and preference surveys were conducted using the size of each component. Through this research, we suggested a method to create a high preference for each component of an evacuation guidance map.

  • As a result of comparing and analyzing the related legislation of each nation, more superior legislative systems should be made to cope with a number of terrors effectively. And also it is required to devise some concrete regulations such as the following in superior legislative systems. First, because it is hard to collect information on terrorism and watch over suspects according to Communication Privacy Protection Law. More in-depth discussion into the issue of surveillance is needed for the protection of lives and property, although public concerns of privacy are a valid point of contention. Second, it is necessary to take complementary measures on immigration as surveillance, since the current Immigration Control Law has restrictions in many ways to hinder efforts to root out terrorists. Third, under the current law on financial activities, it is impossible to block influx of terror financing. Therefore it is necessary to come up with ways of making the punishment procedures. Fourth, considering that convicted terrorists get punished under the standard procedures and precedents, it is required to clearly differentiate between what the terror acts are and what terrorist groups are. Fifth, it is necessary to make use of the private security system to enhance the security system of national facilities.

  • It is provided that seafarers qualified in accordance with STCW(International Convention on Standards of Training Certification and Watch-keeping for Seafarers) convention and code in safety training shall be required, every five years, to provide evidence of having maintained the required standard of competence, to undertake the tasks, duties and responsibilities listed in Chapter VI, section A-VI/1 of the STCW Code A. Every party to the STCW Convention has amended the relevant national regulations according to the above international convention and code. These amended Seaman's Act require the updating safety training which is only five years valid for existing seafarers serving onboard ship on international voyage. And above specified existing seafarers must, as of the 1st January 2017, have documentary evidence of either having completed the training course or updated their training within the last 5 years. In relation to the above international trend, the Korean Ministry of Oceans and Fisheries also has completed an amendment to its Seaman's Act. But, the Korean Seaman's Act has a supplementary provision to exempt the seafarers who have completed STCW advanced safety training from basic safety training. The purpose of this study is to define the problems of above mentioned exemption provisions and to make better policies for improvement. In order to complete the purpose, the research team has conducted an in-depth survey of various foreign cases on STCW safety training. Moreover, the team has suggested an improvement scheme in consonance with Korean shipping industry and society through out this report.

  • Advanced safety vehicle (ASV) equipped with intelligent drivers advisory functions for controlling vehicle to follow the lead vehicle and/or warning drivers on forward traffic impediments according to the roadway and traffic circumstances has been recently developed and on the market internationally. Standardization processes for ASV system functions have been issued in IS0/TC204 Working Group 14 (Vehicle/Roadway Warning and Control System) since 1995. Research projects developing test and evaluation technologies for ASV in establishing safety standards and/or conformity related to the national roadway and traffic circumstances are under study internationally. In Korea, an integrated test and evaluation Program was developed for the assessment of adaptive cruise control (ACC) system under the ITS research and development projects funded by the Ministry of Construction and Transportation (MOCT). This paper demonstrates the integrated test and evaluation Programs for ACC system based on the draft international standard with related to the domestic roadway and traffic conditions. Field tests fulfilled under the scenarios based on the integrated test & evaluation programs for ACC system are discussed along with a review of earlier research work regarding international standards and the safety regulations.

  • This study was conducted to investigate the contents of lead (Pb) and cadmium(Cd) in honeys (n=60) from April to May in 2004 and to provide the scientific basis for heavy metal regulations of Korea Food Code. The samples were digested with acids, then analyzed for the contents of Pb and Cd by an inductively coupled plasma spectrometer (ICP). The contents of Pb and Cd [minimum-maximum (mean)] were 0.189-1.82 mg/kg (0.568) and not detected (ND)-0.016 mg/kg (0.0008) in domestic acacia honeys (n=20), ND-1.702 mg/kg (0.329) and ND-0.243 mg/kg (0.013) in domestic wild flower honeys (n= 18), ND-0.322 mg/kg (0.073), ND-0.027 mg/kg (0.002) in imported honeys (n=13), ND-3.754 mg/kg (0.671) and ND-0.658 mg/kg (0.073) in foreign honeys (n=9) brought by Korean travellers, respectively. According to the results, foreign honeys brought by Korean travellers were detected with the highest level of Pb and Cd. Therefore, we recommend that heavy metals of domestic and foreign honeys should be continuously monitored. It is also thought that these results could be the important references to establish the standard of Pb and Cd in honey.

  • The facilities using LP gas in camping vehicles, which are exposed to safety problems due to the proliferation of domestic leisure culture, are not subject to statutory inspection so, effective safety management measures are needed because the subject or method of safety management is ambiguous. In this study, we tried to propose the safety management measures through the deduction of representative types of camping vehicles, research on the actual condition of LPG facilities in camping vehicles and investigation and review of relevant regulations. Through the results of this study, we expect to contribute to the improvement of the safety management efficiency and safety of facilities using LP gas in domestic camping vehicles.

  • Objectives: As the demand to deal with pathogens in domestic research institutions has expanded and biological accidents have increased, the need for systematic biosafety management in infectious disease laboratories has grown. According to international standards, risk assessment (RA) is required for biosafety management. However, RA criteria have not been clearly established in Korea, so to this end I have attempted to determine RA criteria meeting international levels Methods: In order to provide RA criteria for application, I analyzed the RA criteria in use in the U.S., Europe and at international organizations. In order to ensure the public nature of the RA criteria, I constructed the research model through modified management consulting methodology reflecting the model of Radnor and O'Mahoney. Results: According to the results of the study, existing laboratory biosafety regulations were comparable to domestic laboratory safety laws. Existing laboratory biosafety standards that are designed around risk factors were found to be insufficient. An RA case to be carried out in infectious disease laboratories at the National Institute of Health of KCDC was identified. Conclusion: To establish a systematic risk management system meeting international standards, it was necessary first to harmonize the systems of national and international standards. In addition, in order to provide specific biosafety management on-site, I recognized a need for methodology and planning strategies to discover biosafety management so that it can be carried out as required through the RA of individual laboratories.
