This study is to search cooperation plan about fire investigation based on the public-private partnership. Especially focused on the partnership with 4 sector; the academic world, insurance sector, industrial world, professionalist of private fire investigation. In conclusion, Firstly a partnership with the academic world should have courses or school subject extensions related to fire investigation. Secondly, a partnership with insurance sector should secure trust through unifying estimate standard about the origin of damage. Thirdly, A partnership with industrial company is presented making collaboration team to investigate the fire investigation. Lastly, the partnership with the private professionalist related to fire investigation should strengthen credibility and expertise.

There are a close relationship between natural disasters and train safety. So it is very important to guaranty train safety using reasonable rail-transport operation control against disasters. Therefore, based on the past record of rainfall at failure, rail-transport operation control for railway embankment under rainfall was set up. After slope check list at home and abroad had been analyzed, new slope check list was suggested and site investigations were carried out using this check list. In order to evaluate the stability of railway slopes under rainfall, explanatory variables and subordinate variables were selected for multi-variate analysis and critical rainfall was defined by statistical process. Rail-transport operation control including regional and geological properties was suggested by analyzing the critical rainfall and rail-transport operation control in other country, and this will be a good tool to control train speed under rainfall and to secure train safety.

Almost accidents related with gas have started with the leakage of LPG(Liquefied Petroleum Gas) in the open air. But experimental data of LPG leak jet are difficult to find because the safety of experiment is hard to secure and its phenomenon is not steady but transitional. This study is focused on the phenomena of injection jet of liquid butane to the open air. Simple experiment shows that only liquid butane jet in the open air is possible due to the slow vaporization because of low temperature difference between the liquid and air and low vapor pressure of liquid butane. Comparing with the water, 25~40% more liquid butane flow through the tube under the same pressure difference driving.

Korean apartment buildings have been manhattanized and enlarged, but it caused increase of fire accidents. Fire accidents such as Uijeongbu apartment fire(2015), and Ssangmoon apartment fire(2016) caused many deads because of a lack of emergency exit route awareness. Follow to advanced research, conducted suervey on fire safety awareness. On this study, it will present the basic data based on the result of the survey to secure the life.

Earthwork is very equipment-intensive task and researches related to automated excavation have been conducted. There is an issue to secure the safety for an automated excavating system. Therefore, this paper focuses on how to improve safety for semi- or fully-automated backhoe excavation. The primary objective of this research is to develop the core technology for automated object detection in excavation work. In order to satisfy the research objective, a diverse sensing technologies are investigated and analysed in terms of functions, durability, and reliability. The authors developed detecting algorithm for the objects using laser sensor and verified its performance by several tests. The results of this study would be the basis for developing the automated object detection system.

The facilities of domestic elderly people are getting higher in the facility due to the rapid increase of the elderly population. Elderly people ability to evacuate the facility such as cognition and walking ability is very low. Therefore, it is necessary to secure the safety of evacuation in case of fire, but the evacuation safety measures in case of domestic fire accidents are insufficient. This study is to identify the problems of the safety of evacuation through the fire case analysis and to propose the measures against it.

It is obvious that electrical safety cannot be secured soley by the efforts from public sector including government. With the global trend of deregulation as WTO/TBT agreement comes into effect, foreign countries strive to minimize unnecessary and inefficient regulations in every field by sharing responsibilities with the privae sector to secure international competency in trade. To this same end, in this paper 2 level approach plan is suggested to pave the way to the self-security system in electrical field by introducing self-reliance safety system by stage for pre-service inspection on the electrical installations for private use based on product requirements in terms of performance.

Recently, the nation's elderly facilities have grown rapidly since the implementation of the long-term care law in 2008. Also, older adults who use older facilities are also growing. With the increase in the number of fires, increasing the number of fires is also a social issue. In this study, the study conducted an investigation into the smoke control system to analyze the smoke control methods of the elderly and elderly citizens in order to secure the safety of the elderly facilities in the event of a fire, and investigated the smoke control status of the elderly in Korea.

A study on the fire scenario proposal of residential facilities by using fire statistics. as a result of analyzing residential facilities fires by using fire statistics of national emergency management agency during 2007~2012, fires from carelessness were the most causes. specially, fires during food cooking among carelessness showed the highest occurrence frequency, and followed sparks, neglecting fire sources, and cigarette stubs in order. through this the study suggested fire scenarios according, It is believed that can be used as basic data for applying a secure building in a fire using a basis for fire safety design of buildings in the future this.

It is very important to secure hydrogen acceptability to achieve the hydrogen economy. This study empirically analyzed the factors affecting acceptance by using the results of a questionnaire administered to residents of Jeonju-Wanju Hydrogen Demonstration City. The results indicated that the safety of hydrogen infrastructure and local industry and economic growth positively affected acceptance. In particular, local industry and economic growth were more effective in improving resident acceptance. As policy factors, support for government policies and disclosure of information on projects were also positive factors. As perceptual factors, the higher interest in hydrogen and less safety concerns positively affected acceptability. Therefore, as far as hydrogen safety is concerned, it seems necessary to support local industry development to improve acceptability, disclose information related to industrial development, and introduce targeted experience programs.
