The main purpose of the study is to reduce the accident death rate in the construction industry. To achieve this goal, the safety planning tasks were analyzed and assessed in terms of the importance and preventive effects of the tasks. Through the extensive literature reviews, the safety planning tasks were identified and reviewed by safety managers. based on the safety planning tasks developed in the previous stage, a survey was conducted in order to receive responses by experts with knowledge on the effects and importance of preventive measures for safety. Then, the Importance Performance Analysis(IPA) method was employed to identify the safety manager's tasks that have an effect on performance indicators. Advice and guidance on making the employment rules, etc. (#18) and details about participation and consultation at the Occupational Safety and Health Committee (#16) were found to require revision and improvement of details and guidelines. The effective safety tasks identified are expected to have a critical role in reducing the accident death rate in the construction industry.

Occupational safety and health management expense in construction industry means the monetary amount that the purchaser appropriates to prevent various disaster from happening during the construction period by setting aside a certain amount from subcontract based on the construction type and scale. The current appropriation standard of the Ministry of Employment and Labor has been enforced since its stipulation in 1988 although various policy changes for the safety in construction industry, e.g. the development of occupational safety management techniques in construction industry, changes in construction field site environment, cost depreciation, etc., are happening in Korea and overseas. Therefore, it is required at this point to examine whether the current occupational safety and health management expense appropriation is proper or not on the basis of time trend and the changes in the construction industry environment. Accordingly, this study aims at investigating the appropriation of occupational safety and health management expense for construction industry by the construction type and target expense in response to current construction industry environment and proposing the proper appropriation. The above research result proposes the calibration of the appropriation as specified and stipulated by the Ministry of Employment and Labor by the construction type and target expense, which is necessary to reflect the actual condition of the current construction industry environment.

In terms of construction work, the construction cost is lower than the importance of the construction, and since it is demolished after the completion of the construction, it is treated as a relatively small proportion compared to other construction types. Construction engineers who actually worked on the site talk about the safety of the construction work as the most important work of the various processes to ensure the quality and safety of the construction work. However, it is also true that safety management is difficult for temporary construction because various types of temporary materials are installed at various sites at the same time as construction progresses, and the main construction is carried out using them. Safety accidents in construction work are not much different even if they are carried out in temporary construction. The importance and safety of construction work cannot be neglected in view of the recent trend of large-scale construction, multi-purpose, excavation of large-scale underground spaces, and construction trends that are changing to skyscrapers. The purpose of this research is to secure the safety of Dongbar among the temporary materials used in construction work by using IT convergence technology, and to propose safety management to prevent safety accidents in the construction work.

Additive manufacturing (AM, also known as 3D printing) technology gets attention for various effects in the construction industry. It reveals abilities of process automation, high traceability of resource management, construction period precision improvement, and worker safety. However, unlike the existing construction technology, the development of AM construction process causes trial errors and unpredictable accidents. In the present study, the construction AM process is designed for on-site construction, and it performs with empirical tests. Also, we analyzed the causes of qualitative experimental results.

Recently, the disaster situation has been diversified and compounded worldwide as well as in Korea. And the damage scale of each disasters have increased, and following economic loss is also increasing immensely. In Korea, especially the out break frequency of large-scale disasters has increased. Disasters caused by earthquakes are also very likely to occur. When a major accident such as Mauna resort collapse accident, Ferry sewol sinking accident occurred, systematic emergency medical care at the site at the time of disaster occurred in order to operate an emergency medical facility corresponding to the site, which is not systematic. The need for this service is urgent. If highly reliable emergency medical system function at appropriate times in the disaster site, secondary damage can be reduced and the whole situation would be back to normal shortly. Therefore, it is necessary to provide an emergency medical system capable of quickly and safely responding to disaster sites in relation to various damage scale. For the purpose, thorough analysis on mobile medical units of inside and outside the country was accomplished. As a result, Mobile Medical Unit of outside the country are trailer type, tent type, container type etc. At home, these types have been studied and will be proposed early next year as a temporary solution. Here we introduce suitable types for our country.

This paper presents the path model that defines a causal relationship between the construction workers' personal characteristics and their safety behavior at job-site. The personal characteristics and the safety behaviors which should be incorporated into the theoretical model were identified and established by conducting literature survey.. The model was verified by administrating survey questionnaires to the 399 construction workers who are actively engaged in construction job-sites located in Daegu metropolitan city and Kyungpook province. The data obtained from the respondents were statistically analyzed using SPSS18 and AMOS18. It is confirmed that safety behavior is directly affected by sincerity, openness, and extroversions. In addition, it is indirectly affected by stress reaction, safety motivation, and safety knowledge as well.

About 50% of disasters occurring at domestic construction sites are caused by the accidents not wearing personal protective equipment. Under the current statutes, employers are required to provide personal protective equipment and workers are required to wear personal protective equipment. However, there is insufficient compliance with wearing personal protective equipment on site. This study is about the measure of improving the system to the way of purchasing, wearing and managing personal protective equipment by individual workers, and refunding the cost of personal protective equipment to workers. It is expected that this thesis will improve the system of personal protective equipment effectively, and contribute to the prevention of disasters by settling the culture of wearing personal protective equipment.
