The purpose of this paper is to investigate the basic data (e.g. education experience and awareness of the installation situation, and usage of indoor fire hydrants) for the effective planning, progress and improvement of fire safety education. For this purpose, we surveyed 198 participants and an analysis of the frequency and descriptive statistics based on the survey data was carried out using SPSS 20.0 for Windows. The analysis results showed that 87.9% of the research participants live in accommodation with indoor fire hydrants installed and that, among them, 17.7%, did not know their location. 63.6% of the research participants, had received fire safety education but, among them, 31.0% had never been educated about the use of indoor fire hydrants. The main type of fire education was instructor-led training, which represented 50.0% of the participants. We believe that the results of this paper will serve as a basis for efficient adult fire safety education.

The east coast of the Korean Peninsula is susceptible to fires because of the low rainfall in winter and spring, and large forest fires have occurred in this area. Lack of fresh water to combat fires has hampered efforts to prevent widespread forest fires in this region. Seawater has not been used as a suppressant because of possible detrimental effects of salt. We investigated the mobility of saline water in the forest soil and their effect on the microbial activity. Using a fire-fighting helicopter, seawater was sprayed over three plots (50 × 100 m) located on the eastern slope of the Baekdu mountain range in South Korea in April, 2011. We sampled the soil in April 4, May 20, and August 5 to determine the amount of salt that remained in the soil. The electrical conductivity value of the soil decreased to <400 μS/cm over a 1-month period. Approximately, four months after the application of seawater, the electrical conductivity value and Na⁺ content in all treatment plots did not significantly differ to those of the control plot, and total microbial activity also recovered to that of the control. Our results indicate that the amount of rainfall, soil physical-chemical properties, and topological factors may be a critical factor determining the mobility of saline water in forest soil.

A fire is occurring increasingly every you and the damage is bigger in proportion to the number. Therefore a fire is classified as a serious calamity. It is important to evacuate and fight a fire by early Perception. However, if the alarming sound is not perceived when a fire breaks out the damage could be expanded. From this point of view, this study aims to analyse the correlation between alarming sound sources and sound quality parameters through psycho-acoustic experiment using Korean vocabularies extracted by existing study. The sound sources more dangerous, tense and urgent were chosen. The results from this study are as follows: 1. airraid, klaxon2 and S.O.S got a point more than conventional alarming sound.2. correlation coefficient between Loudness(L) and Unbiased Annoyance(UA) was highest with 0.63 md Sharpness(S) and Roughness(R) was -0.40 and Fluctuation Strength(FL) and Tonality(T).

Purpose: This study proposed an improved method of teaching cardiopulmonary resuscitation (CPR). Methods: A teaching method for CPR using a song was evaluated. To validate the effect of this teaching method, we performed a comparative reference test against a traditional CPR lecture-oriented education method. A total of 202 study participants were enrolled in this project. Half were taught by the traditional CPR education method, and the other half were taught by the alternative educational method using a song. Results: The results for those educated by the traditional lecture-oriented method showed scores of 4.84 / 6.00 (Mean of knowledge) and 70.22 / 100 (Mean of practice ability for CPR). The results for those educated by the alternative method showed scores of 5.26 / 6.00 (Mean of knowledge) and 74.13 / 100 (Mean of practice ability for CPR). The alternative educational method utilizing a song improved the results on written and practical examinations. This improvement could be attributed to the effect of music on memory circuits in the brain. Conclusion: We believe that the results of this study will help to improve the success rates of CPR.

The aim of this study was to reduce the number of negligent accidents by improving the fire safety consciousness of infant and child teachers working in a day care center. For this purpose, 242 early childhood teachers working in the national nursery school in Daejeon and Chungcheongnam-do were surveyed. For the survey, the questionnaire consisted of job satisfaction, teacher's efficacy, and fire safety consciousness. The survey data were analyzed using the SPSS 20.0 win program. The factor of job satisfaction and teacher's efficacy had a significant positive influence on the fire safety consciousness of the early childhood teachers (<.05). The teacher's efficacy was found to mediate the relationship between the job satisfaction and fire safety consciousness. In conclusion, this study suggests that teacher's fire safety consciousness is high when the teacher's job satisfaction and efficacy are high. This study is expected to contribute to basic research to increase the teachers' consciousness of fire safety.

Instruction and prevention of the safety for a fire have been performed continuously by nation. However, the accident due to a fire is not decreasing and causes a serious calamity to people. It is at the initial stage of fire burning that the most effective way to reduce damage is to evacuate and fight a fire. When a fire burns, the equipments reporting to other person or organization concerned are called 'acoustic reporting equipment'. Among those equipments reporting to person, 'a fire bell' is the easiest equipment to approach. Observing the behaviors of people when a fire burning, some are in a quiet indoor, some in a room with other people, some in a square with many people and some in indoor filled with smoke etc. This study aims to find out an acoustic reporting signal appropriate for visual information. For the experiments, visual-auditory experiments were performed through reporting signals and visual informations with several situations that is able to be faced at when a fire burns.

Most of the Korea temples of cultural property are wooden buildings and easy combusted. They are often located in mountain area far away from the city. It is very difficult to approach the fight area. The putting out is very difficult in the initial fire time. And for protecting the cultural property in the long-term continuous fire source there are some restrictions in water source and suppression system. In this paper the initial putting out fire due to the forest fire and the protection of cultural property in the long-term continuous fire source were researched. The improved project about fire control facilities of the Korea cultural property was proposed. In the proposed project the facilities using Water mist which can reduce more loss than existing facilities using water are applied. In view of the topographic position the method of eliminating the energy of combustibles and wall for cutting off the heat in the fire control facilities are also mentioned.
