As the distribution of vehicles and logistics increases due to the development of human civilization and the increase in population, various roads play an important role in domestic traffic and transportation. However, the recent emergence of large cities and new cities is causing traffic problems, and the increase in roads is inevitable for the smooth distribution of vehicles and logistics. In Korea, mountainous regions occupy 70% of the country, so tunnels are used to open roads. Without this, it is difficult to open the road. Currently, there are 3,720tunnels (as of December 31, 2023) installed on high-speed national highways, general national highways, and local roads nationwide, with a length of 2.499 and increasing every year. Accordingly, fire accidents in tunnels will also increase, and due to the nature of tunnel fire accidents, there is a high probability that they will escalate into large-scale disasters, resulting in casualties and property damage, as well as significant social losses due to the disruption of logistics transportation, etc. As the possibility of potential hazards is increasing, the purpose of this study is to build a safe and efficient tunnel system by optimizing maintenance and management for fire and disaster accidents in tunnels.

This study attempted to analyze the comparative advantage in terms of disaster safety costs in verifying the effectiveness and economic feasibility of the high-performance water-bulwark system in the pole tunnel, which was recently promoted as a part of the acceleration of vehicles. The tunnel to be analyzed was divided into a short tunnel(Anyang, Cheonggye) and a long tunnel(Suraksan, Sapaesan). As a result, it was analyzed that 25% of the improvement effect would occur if one lane was secured by applying the Water-Bulwark System. It was analyzed that this is because the time value cost, which accounts for a large proportion of the traffic congestion cost of short tunnels and pole tunnels, differs depending on the congestion time and traffic volume, not the length of the tunnel.

This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as “lack of procedures for listening to opinions and preparing improvement measures” for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

다양하게 변화하는 재난양태와 기후변화로 인한 빈번한 재난발생뿐 아니라 생활수준 향상 등의 이유로 재난안전에 대한 국민적 관심이 증대되고 있다. 이와 연계하여 재난안전 산업에 대한 요구도 증가하고 있다. 그 동안 다양한 재난안전산업 육성 및 활성화 정책이 수립되었지만, 국가주도의 정책이 대부분이었고, 민간분야와 국민관심도가 반영된 정책은 부재한 상황이다. 따라서 본 연구에서는 국민관심도를 고려한 재난안전산업 육성방안 수립을 위하여 소셜미디어 분석을 활용하는 방안을 제안하고자 하였다. 재난안전분야의 국민관심도를 분석하기 위하여 최근 3년간의 소셜미디어를 대상으로 분석을 실시하였다. 분석 결과, 국민은 실제 발생했던 재난에 대한 내용, 즉각적으로 실생활에서 필요한 분야에 대해 관심도가 높은 것으로 나타났다. 또한 실제로 경주 지진발생 당시 재난 관련 소셜데이터가 급증하는 것으로 나타났고, 뉴스에서는 피해상황 등에 관한 내용이 많은 반면, 트위터와 블로그에서는 구호물품, 대피요령 등에 관한 내용이 주를 이루고 있는 것을 확인하였다. 본 연구의 결과로 국민적 관심도를 분석하기 위한 방법으로 소셜미디어 활용방안에 대한 가능성을 확인하였고, 재난안전산업의 민간분야 확산 차원에서 국민관심도를 반영한 재난안전산업 정책 수립방안을 제안한다.

Disaster and safety budget can be characterized as a large-scale public asset on which the government has a significant role. It is of a crucial importance to properly allocate the limited national budget to various areas as necessary. Higher investment efficiency of the budget related to disaster and safety management requires distribution criteria based on relevance and efficiency. Currently, the budget related to disaster and safety management is orchestrated through the prior consultation system. However, there is still no clear framework for reviewing the investment direction and setting the priority investment areas by prior consultation. This study analyzes the status and characteristics of disaster and safety management projects by damage type and proposes a structured system for prioritization. This framework can be useful in selecting the areas that need priority investments by damage type of disaster and safety management projects, thereby contributing to improving investment efficiency.

In changes of social environment, change of the use of land due to the change of residence type, industry and urban structure is an influential factor to safety vulnerable social group. From PTSD from disaster experience point of view, experience of disaster, damage from disaster, witness of disaster make people experience anxiety and confusion, increase the anxiety toward disaster and lead to difficulty in daily lives. As for the result of analyzing anxiety factors regarding disaster damage potential composed of 20 items of safety manager, damage potential of sink hole which recently rapidly increased was the highest, and followed by anxiety from safety damage potential of family, anxiety from phone call damage. Likewise, if the anxiety toward disaster damage potential is digitized, it contributes to setting safety management planning for disaster prevention as it visualizes the risk.

In addition to improving economic growth and development of advanced production technology brings many benefits to our society, but if the growth of this still has the shadow of accidents exists. In particular, the construction site has seen a significantly higher accident rate figures despite efforts on disaster prevention. Among the various methods of reducing the need for disaster safety education industry it has become very stressed its importance through many studies. When a disaster causes significant share of the construction industry due to the lack of educational causes, including technical causes, managerial causes, classification and educational causes of this ateumyeo safety awareness and knowledge account for large proportion. In the health and safety education, centered on the subjects of education supervisors will be able to reduce the real and effective industrial disaster education should be run.

Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.

The influences of scatterer and absorber in turbid material by light scattering on silica fume of additive were interpreted for the scattered intensity and wavelength. The molecular properties have been studied by Monte Carlo simulation in resin of New Austria Tunnel Method. It has been found that the effects of optical properties in scattering media could be investigated by the optical parameters(μs, μa ,μt). Monte Carlo Simulation method for modelling of light transport in the civil engineering and construction field was applied. The results using a phantom were discussed that the distance from source to detector is closer, and scattering intensity is stronger with those obtained through Monte Carlo Simulation. It may also aid in designing the best model for coatings and corrosion for the durability of metal constructions.

The accident which is caused by the press work remains a Permanent obstacle in worker's hand or arms, the disaster ratio is high and the fatal case is many. Mainly Like this accident occurs because the hand to enter with inside of the press die, therefore, basic countermeasure is the safety press. In order to prevent access to mechanical moving part by the hand or any part of the body, it is important to making a safety die design Structurally. It presents the design of the safety press die with suitable structure in the Product's attribute which it had shown in samples, There is a possibility of being difficult because the attribute of safety die design that had present all the productions from research does not agree each other. but because the representative process which is used most at sample had designed, If you were imitates with safety die design base which is presented from this research, It comes to be thought to be the part which can are used at the various sides.

New governance in the area of disaster management(New Governance) of the Safety Building in the form of public-private network as required in this era, SWOT can provide a strategic way to build public-private partnership recognized the necessity for a more efficient way. Between government agencies, private organizations and government and private organizations for the network between the systematic approach based on mutual trust, and participation by the activation of the meaning of seeing places studied. Partnership for Disaster Management as a result of the settlement than if the existing disaster management system for disaster response system more effective and efficient functioning in reducing human and material damage is expected to contribute are getting out.

If you examine the Industrial Disaster Analysis Content that occurs every year in the small and medium enterprise, industrial disaster occurs because of manager's lack of safety and worker's unprepared safety education. Therefore effective safety education systems are needed to offer adequate knowledge and technology to the workers. On this research, to give an effective education way to decrease industrial disaster we administered to the workers who are in charge of 300 workplace in Incheon area to search actual condition of industrial disaster and to disclose a link between industrial disaster and industrial safety education. We put in effect on frequency study and examined x2 using SPSSWIN 10.0. On the research, the results shows that the industrial safety education and training are in effect regularly and the satisfaction are low. But the manager's satisfactions are high through safety education. So it shows that we need to find a way to put in effect safety education to satisfy the workers.
