In this paper, Fire resistance test was carried out in accordance with the change of the insulation conditions on the exposed side and unexposed side of the coaming to obtain optimal insulation conditions for class H-120 insulation in connection with specimen-1 of the preceding paper for the evaluation of fireproof performance for fire dampers according to hydrocarbon fire conditions. As a test result, specimen-2(88 mm, $171^{\circ}C$) was satisfied class H-120 insulation, but specimen-3(76 mm, $181^{\circ}C$) was exceeded thermal insulation acceptance criteria at 110 minutes, therefor, specimen-2(88 mm) is optimal insulation conditions as possible lightweight than specimen-1. Test result comparison, we concluded that temperature rising of the coaming insulation surface was influenced by conductive heat from the bulkhead, and coaming surface was influenced by radiant heat from blade & coaming.

The OECD defines regulatory reform as both better regulation and deregulation, and emphasizes that governments must continue to regulate in areas such as environmental quality and safety. In contrast, Korean regulatory reform in fire services in the 1990s shows quite a strange trend, having been carried out only to the direction of softening and abolishing regulations. In the UK, fire prevention legislation has been strengthened since the enactment of the Fire Precautions Act 1971, and the Building Regulations 1991, which apply to all new buildings including a private house, require that there should be at least one smoke alarm on each floor. This research shows that the tightening of fire prevention legislation in the UK has promoted fire safety, which is very instructive for Korean fire services. In order for Korean fire services to protect citizens'lives and property from fires, one of basic directions of regulatory reform, to improve the quality of regulations relating to safety, health and the environment, should be observed strictly. Moreover, the flexibility of the basic direction of regulatory reform should be ensured so that the regulations concerning safety could be even increased under the overall reform strategy of reducing all regulations.

When the fire takes place in Nuclear Powr Plants(NPPs), the reactor should achieve and maintain safe shut-down conditions and minimize the radioactive material released to the environment. The U.S. Nuclear Regulatory Commission (NRC) has issued numerous generic communications related to fire protection over the past 20 years, after it issued its requirements in the Fire Protection Rule set forth in Title 10, Section 50.48 of the Code of Federal Regulations (10 CFR 50.48) and Appendix R to the 10 CFR 50. The and Nuclear Energy Institute (NEI) has developed a Methodology for Risk Informed Fire Safe-Shutdown Analysis, which is related to the Deterministic Method for Multiple Spurious Operations solutions. The aim of this study was to identify, achieve, and maintain Post-Fire Safe-Shutdown of the Main Control Room (MCR) of the CANDU reactor, even though one train of the multiple Safety Structures, Systems, and Components (SCCs) fail by the technical specification and analysis method.

This paper aims at the development of an knowledge base for an electrical fire cause diagnosis system using the entity relation database. The relation database which provides a very simple but powerful way of representing data is widely used. The system focused on database construction and cause diagnosis can diagnose the causes of electrical fires easily and efficiently. In order to store and access to the information concerned with electrical fires, the key index items which identify electrical fires uniquely are derived out. The knowledge base consists of a case base which contains information from the past fires and a rule base with rules from expertise. To implement the knowledge base, Access 2000, one of DB development tools under windows environment and Visual Basic 6.0 are used as a DB building tool. For the reasoning technique, a mixed reasoning approach of a case based inference and a rule based inference has been adopted. Knowledge-based reasoning could present the cause of a newly occurred fire to be diagnosed by searching the knowledge base for reasonable matching. The knowledge-based database has not only searching functions with multiple attributes by using the collected various information(such as fire evidence, structure, and weather of a fire scene), but also more improved diagnosis functions which can be easily wed for the electrical fire cause diagnosis system.

In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

Recently, increases in major disasters such as fires, earthquakes and typhoons have raised public expectations for safety. In addition to this increase in expectations of safety, the government continues to push for more manpower and better treatment for firefighters who are operating in the disaster scene. Despite the improvement of working conditions and increased welfare for firefighters, however, the incidence and turnover of various mental diseases continues to increase. It is reported that many of the diseases such as post-traumatic stress disorder and the turnover of firefighters are due to a mismatch in individual's personality and work environment. In this study, 108 firefighters were evaluated for their vocational aptitude in the new curriculum. Based on the analysis results, new firefighters were proposed to provide employment and education training improvements, and to provide job security suitable for the individual's personality type through the introduction of the vocational aptitude test for firefighters who are working in the fire service. In addition, we would like to use the vocational aptitude test as a material for reducing post-traumatic stress disorder and increasing turnover through long-term tracking and observation, rather than from a one-off perspective.
