Construction sites have various risks, and safety managements are enforced based on the law such as Industrial Safety and Health Act, etc. Safety management by the law saves lives and preserves health of workers by removing and understanding risks in advance. When the emergency situation has come, poor response causes loss of lives and physical damages. This study suggests basic strategy that can mitigate the industrial disaster in all construction sites. A survey was conducted to identify the current safety consciousness and to evaluate first aid ability of coworkers. Finally, four measures were suggested: (1) designating muster points; (2) hiring occupational health managers; (3) increasing the first aid ability of coworkers; and (4) carrying safety brochure. The proposed suggestions can be helpful in mitigating the construction disaster, and in responding the major accident efficiently within a short time.

This study of small & Medium-Sized construction sites construction disaster prevention technology conduction-site visits from the map results report by the inspector on-site advice and technical guidance for the analysis of deficiencies and potential construction of disaster revealed the potential factors causing an accident as follows. As a results, Should not be a once a month visits. Therefore should be changed at least twice a month to help prevent accidents of this system is to be judged.

With a view to analyzing the influential factors and their prioritization in association with the loss from construction disasters, this study has presented relative weighted value and importance for each category of loss by making a systematic classification of costs for non-insured categories (indirect costs) and conducting AHP analysis based on results of a survey of specialists. Through the study, first, I have divided the larger classification of loss factors into human loss factor, financial loss factor, special cost factor, and managerial loss factor, and, second, have presented prioritization of loss categories by allotting scores based on weighted values after calculating weighted value through pairwise comparison of loss levels. Based on these results of the study, we should be able to qualitatively calculate the loss costs that construction disasters inflict on business, promote rational decision-making and efficiency in spending related to a disaster, and compare it against safety investment designed to reduce disaster loss from the perspective of business strategy.

A cable stayed bridge under construction has low structural damping and is not as stable as the completed bridge. Control countermeasures, such as the installation of energy dissipating devices, are thus required. In this study, the general procedure and key issues on adopting an active control device, the active mass damper (AMD), for vibration control of cable stayed bridges under construction were studied. Taking a typical cable stayed bridge as the prototype structure; a lab-scale test structure was designed and fabricated firstly. A baseline FEM model was then setup and updated according to the modal parameters measured from vibration test on the structure. A numerical study to simulate the bridge-AMD control system was conducted and an efficient LQG-based controller was designed. Based on that, an experimental implementation of AMD control of the transverse vibration of the bridge model was performed. The results from numerical simulation and experimental study verified that the AMD-based active control was feasible and efficient for reducing dynamic responses of a complex structural system. Moreover, the discussion made in this study clarified some critical problems which should be addressed for the practical implementation of AMD control on real cable-stayed bridges.

In this study the frost penetration depth along national roads in Korea were measured and analyzed over several years. The frost penetration depth was analyzed with respect to the Provinces of Korea and sunny/shaded areas. Additionally, the measurement results were compared to the formular of the US Army Corps of Engineers and Terada in Japan.

현재 국내에서는 상대적으로 큰 재난이 자주 발생하지 않음으로 인해 대피소 이용률이 적어지고, 자연스럽게 대피소 유지 관리에 소홀해왔다. 그러나 최근 풍수해 및 지진 등의 다양한 자연재난과 사회 재난들이 발생하고 있는 상황에서 대피소를 재점검하고, 재구축할 필요성이 있다. 이에 본 논문에서는 대피소 및 방공호 구축의 선진국인 스위스의 사례 분석을 통해 앞으로 국내 대피소 구축 시 고려하여야 할 요소 및 방안을 제시함으로써 현재 국내 대피소의 문제점을 개선하는데 도움이 되고자 한다.
