The three different polymer compounds were manufactured with the three different fire retardant (silane coated magnesium dihydroxide) contents, 180, 200, 220 phr, for making cable sheath for ship industry. In the research, ethylene-vinylacetate, polyethylene as matrix polymers and ethylene-vinylacetate grafted maleic anhydride as coupling agent were selected for compounding with fire retardant, closslinking agent, plasticizer, and other additives. In the evaluation. ΔT, Mooney viscosity, and tensile strength increased with the content of fire retardant. But it was found that too much fire retardant damaged aging resistance and cold resistance of the polymer compound.

Four different polymer compounds were manufactured to make cable sheaths for the shipping industry. Two kinds of ethylene vinyl acetate (EVA) as the main matrix polymers and EVA-grafted maleic anhydride (EVA-g-MAH) as the coupling agent were selected for compounding with fire retardant, crosslinking agent, filler, plasticizer, and other additives. The properties of the four compounded materials were investigated with different contents of the fire retardant, silanecoated magnesium dihydroxide (S-MDH). In the rheology evaluation, the $t_{60}$ and ${\Delta}T$ values increased with increasing S-MDH contents. On the other hand, the tensile strength decreased with increasing S-MDH content due to a relative decrease in binder polymers. With increasing S-MDH content, fire resistance increased, but cold resistance showed no obvious enhancement due to the polar effect of vinyl acetate in EVA.

In this paper, we introduce a fire detection system using context-aware sensor. In existing weather and based on vision sensor of fire detection system case, acquired image through sensor of camera is extracting features about fire range as processing to convert HSI(Hue, Saturation, Intensity) model HSI which is color space can have durability in illumination changes. However, in this case, until a fire occurs wide range of sensing a fire in a single camera sensor, it is difficult to detect the occurrence of a fire. Additionally, the fire detection in complex situations as well as difficult to separate continuous boundary is set for the required area is difficult. In this paper, we propose an algorithm for real-time by using a temperature sensor, humidity, Co2, the flame presence information acquired and comparing the data based on multiple conditions, analyze and determine the weighting according to fire it. In addition, it is possible to differential management to intensive fire detection is required zone dividing the state of fire.

This thesis investigated accidents in relation with hazardous materials such as university laboratories in our country. In addition, this thesis investigated how the courses, hazardous materials, are managed, centering on Seoul, Gyeonggi, Busan, Gwangju, Gyeongbuk, and Chungbuk Fire Service Academy as well as National Fire Service Academy, and investigated how the courses, hazardous materials, are managed, centering on the courses in relation with fire service in universities, too. This thesis, also, performed a questionnaire survey on the education in relation with hazardous materials, objecting fire service officers on working who took education in respective provincial fire service academies and National 119 Rescue Services. This thesis analyzed the results of questionnaires, found problems in the current education about hazardous materials, and presented effective learning methods as the courses, hazardous materials, management methods, centering on new experiments. In addition, this thesis tried to present education plans with which people could prevent from the accidents in relation with hazardous materials.

The aim of the study intends to investigate the recognition of fire safety of traditional market employee in Masan city and to provide the base data for the fire safety. The results of the study are as follows. The traditional market employee have high interest in fire safety and recognize that the possibility of fire is high in market. The traditional market employee of 46.0% takes fire safety education and preferred self-government merchant association in market as education place. This study shows that the traditional market employee of 41.5% recognize a fire escape route. In order to prevent the fire of traditional market, the strong activity of market fire staff and the periodic fire inspection of fire department are recommended.

Since fires in uncontrolled environments pose serious risks to society and individuals, many researchers have been investigating technologies for early detection of fires that occur in everyday life. Recently, with the development of deep learning vision technology, research on fire detection models using neural network backbones such as Transformer and Convolution Natural Network has been actively conducted. Vision-based fire detection systems can solve many problems with physical sensor-based fire detection systems. This paper proposes a fire detection method using the latest YOLOv8, which improves the existing fire detection method. The proposed method develops a system that detects sparks and smoke from input images by training the Yolov8 model using a universal fire detection dataset. We also demonstrate the superiority of the proposed method through experiments by comparing it with existing methods.

To accomplish the purpose, the current study drew factors affecting the transfer of education and training through a review of domestic and overseas literature, and aimed to empirically investigate whether these factors actually affect the transfer of education and training of fire officers. The results showed that significant variables affecting the degree of perception on the transfer of education and training were in the order of work relationship, learning culture, peer support, self-efficacy, learning motivation, learning ability, and teaching method.

The purpose of this study is to investigate the perception of fire safety education in middle and high school teachers. The results of this study provide basic data necessary for future school safety education. The research was carried out using a questionnaire given to 317 school teachers. The frequency of the questionnaire was calculated from frequency analysis using SPSS version 19.0. A chi-square test was conducted to verify the analyzed questionnaire data. Cronbach's alpha for fire safety awareness in the respondents is 0.845, which is very reliable. According to the results of the survey, fire safety education currently conducted in schools is aimed at having a safe lifestyle and respect for life. The training is conducted once every six months, on average, and training time is 30 to 45 minutes. Fire safety education in schools is conducted in the form of experience-oriented education in cooperation with fire-related organizations following the plan of the school. Educational texts are used and utilized through the Internet and in related publications. Under the present circumstances, it is necessary to secure sufficient space to run an experience-related education program and to actively participate in the students' fire safety education at the school.

The purpose of this study is to analyze the types of latent profiles of high school students' fire safety awareness and to identify the characteristics of related variables. For this purpose, a survey was conducted from March 22 to May 25, 2021 for 1054 high school students (male; 569, female; 485) in 3 cities, in Jeollabuk-do. The latent profile was analyzed using a scale consisting of 4 sub-factors: 'fire prevention', 'fire preparedness', 'indirect fire response', and 'direct fire response'. It was checked whether there were differences according to the inter-individual differences of the latent group. As a result of the analysis, fire safety awareness of high school students was classified into three latent profiles. The three groups were named 'High Perception Type', 'Moderate Perception Type', and 'Low Perception Type' according to their types. In fire safety awareness, there is a significant difference in the individual differences according to the gender and academic achievement of the latent profile. These results are meaningful as the first study to analyze the latent profile of high school students' fire safety awareness, and it is also meaningful to provide a useful basis for the contents and methods of customized fire safety education by identifying the tendencies of spontaneous groups and their fire safety awareness.
