Smoke is recognized as the major killer in fire situation. smoke often migrate to building locations remote the fire space, threatening life and elevator shafts frequently become smoke-logged, there by blocking evacuation and inhibiting rescue and fire fighting. It is the aim of this study to investigate and analyze the research trends of smoke movement in Fire.

Fire trends in Korea, Japan, and the United States were analyzed in this paper. The number of fires in the U.S. tends to decrease greatly from 3,264,500 cases in 1977 to 1,687,500 in 2002. There have been an estimated 60,000 fires annually more than 20 years in Japan, at the peak of 73,072 cases in 1973. In case of Korea, 5438 fires occurred in 1980. However, fires increased rapidly up to 36,169 cases in 2001 and 31,372 cases in 2003. In addition, fire statistics processing methods and fire statistics reports were analyzed. The result was that Korea was behind most of the three countries. Therefore I confirmed that we need not only to study systematical processing methods of fire statistics in order to get confidence on those like accurate estimating fire data analysis, but also to publish variable and specific reports on fires for the purpose of analyzing fire data.

The fire accident cases of several countries such as Korea, Japan, United States, etc., were collected and compared statistically. The trends of fire accidents in several countries will help us establish detailed plans for fire protection and reduce the possible fire accidents in the future. For construction of data base system, the program FADS was developed, which is operable in Windows environment.

Fire engineering design method based on structural performance of buildings has been developed through all of the worlds since the early 1960's. But recently the worlds have been changed rapidly in aspects of global community and mutural free trade circumstances. Therefore the concepts of fire design on structural performance need to harmonize among countries that have their own unique regulations and ISO TC 92 and SC 4 have worked in order to make the united international standard.

In order to minimize casualties in case of a fire in a building, it is necessary to anticipate the time required for evacuation of occupants and the delay in evacuation in advance, and prepare countermeasures for possible occurrences. In fact, various factors that cannot be predicted exist and cannot be considered by excluding them, so the risk is predicted and evaluated through quantitative evacuation modeling. In order to understand this, we analyzed domestic and international evacuation modeling research trends. For about 40 years, starting with the characteristics of human movement, an evacuation modeling technique based on scientific methods has been developed through actual fire accident cases and various real-world experiments with humans. Then, in order to analyze the natural reaction of humans, which has a decisive influence in the recognition and decision-making phase, evacuation modelling studies have been conducted in depth using psychological and physical experimental methods.

Due to the development of the urban economy, high-density buildings and skyscrapers have continued to increase in order to alleviate high population densities and to make efficient use of urban space. However, a fire in a high-rise building is a disaster that can lead to massive casualties and property damage because of the difficulty of firefighting and escaping. Various studies have been conducted on these high-rise buildings because they are sympathetic to these difficulties all over the world. In this paper, trends of researches and technologies related to fire in high-rise buildings are analyzed synthetically through thesis and patent data. In other words, we explored the trends of various studies that have been carried out so far through the thesis, and performed technical monitoring on actual implemented technology and newly implemented technologies through patent data. Through this research, we have studied the present and the future of technology for high-rise building fire.

Market-oriented networks support various tasks in the market domain. We analyze trends in structural changes of such networks to adapt to preferences in general market movements. This analysis is different from conventional ones that focus on specific technologies. Instead, we focus on the paradigm shift of network technology from connectivity functionalities to platforms supporting business domains for direct modeling. Moreover, we analyze current development efforts of technologies based on popular and realistic solutions such as FIWARE, 5GinFIRE, IBN, IDN, and HNSP. Remarkably, we detail HNSP as an open research and development platform to experiment with business models and enable co-building with developers. We observe a clear paradigm shift of communications technology from a closed to an open job-shop style.

As the widespread adoption and proliferation of electric vehicles continue, the secondary battery market is experiencing rapid growth. However, lithium-ion batteries, which constitute a majority of secondary batteries, present high risks of fire and explosion. Solid-state batteries are thus garnering attention as the next-generation batteries since they eliminate fire hazards and significantly reduce the risk of explosions. Against this background, the study aimed to analyze research trends and provide insights by examining 2,927 domestic papers related to solid-state batteries over the past decade (2013-2022). Specifically, we used topic modeling to extract major keywords associated with solid-state batteries research and to explore the network characteristics across major topics. The changes in research on solid-state batteries were analyzed in-depth by calculating topic dominance by year. The findings provide an overview of the emerging trends in domestic solid-state battery research, and might serve as a valuable reference in shaping long-term research directions.
