During the construction work, many deaths and injuries have occurred in the formwork. This study aims to analyze the perceptions of construction workers about the disaster of formwork collapse. In this study, the IPA(Importance-Performance Analysis) technique was used to analyze the perception of construction workers and derive urgent factors for improvement. As a result of IPA analysis, the fourth quadrant factor needed to be improved first, and the second quadrant factor needed effort distribution. Therefore, it is judged that this study can be used as basic data for safety management and disaster prevention activities.

고수압 시공 조건에서는 시설물 자체의 건설로 인하여 발생하는 주변지반의 이완 및 손상의 발생 그리고 시설물내로의 해수의 유입을 방지하기 위한 차수 및 지수설계 및 시공이 중요한 관건이다. 그라우팅 공사는 현재 지하철건설, 고속 철도건설, 각종 산악터널건설, 하천 저수지 재방 신설 및 보수공사 등에 년간 수조원 대의 시장규모를 형성하고 있지만, 설계 및 시공관리에 대한 관리기준이 정밀하지 못하여 경험적인 판단에 의존하는 부분이 너무 많아 경제적 손실도 매우 클 것이라고 쉽게 단정할 수 있다. 그라우팅 기술은 국가적 차원의 대규모 중요 건설공사 현장에서 필수적인 기술로 사용되고 있지만 기술에 대한 인식이 빈약하고 정립된 관리기준이 부재하여 신뢰성의 낙후가 심각한 실정이다. 따라서 본 연구는 고수압 조건에서 지반재해 저감을 위한 최신 그라우팅 시공관리기술에 대한 기초 연구를 제공함이 그 목적이다.

연구목적:소규모 건축현장은 체계적인 안전관리활동이 미흡하고 건설현장의 특성상 외부환경의 요인으로 생산구조가 복합적이고 건설장비의 위험성 등으로 인해 산업재해의 가능성이 매우 높은 실정이다. 소규모 건설현장의 재해예방을 위한 위험요인을 도출하고 재해를 줄일 수 있는 실무적인 위험성평가의 기법 중 체크리스트 방법을 제안하고자 한다. 연구방법: 문헌조사와 재해사례를 분석하여 위험요인을 도출하여 위험요인 항목을 중심으로 소규모 건설현장에 적합하고 효율적인 위험성평가의 체크리스트를 위한 세부작업을 분류하였다. 연구결과:위험요인을 6개의 대분류로 구분하고 실질적인 작업공종을 중심으로 29개의 세부공종을 분류 하였으며 이에 따른 세부작업을 80개로 구분하였다. 결론:소규모 건축현장에 적합한 위험요인을 분류체계에 따라 정리함으로써 건설현장에 부족한 전문성을 보완할 수 있고 보다 쉽게 위험요인을 도출하여 안전대책수립을 통한 재해감소를 기대할 수 있을 것으로 보인다.

During disaster response, prioritization of limited resources is one of the most important but challenging tasks. At the same time, it is imperative to timely provide to the rescuers with the adequate heavy equipment to facilitate lifesaving operations. However, supply of high demand equipment is usually insufficient during the initial phase of disaster response, challenging lifesaving operations. At the same time, resources outside of the disaster affected zone converge into the area to assist the response efforts, which is the effect of convergence that often made resource coordination challenging in large scale disasters. Meanwhile, the initial condition of the disaster is usually best known by civilians already at the area before and during impact of the disaster. The knowledge of the civilians is not always received and considered by the responding organizations. With the help of these civilians, critical information such as victim location, infrastructure damage, and risk condition could be better know before any response actions are taken. To efficiently collect information and utilize the converging resources, this paper proposes a geospatial information repository for initial condition reporting and update to guide search and rescue operations and deployment of equipment with safety considerations for the rescuers in large scale disaster response scenarios.

During disaster response, prioritization of limited resources is one of the most important bust challenging tasks. At the same time, it is imperative to timely provide the rescuers with the adequate equipment to facilitate lifesaving operations. However, supply of high demand equipment was insufficient during the initial phase of disaster response, challenging lifesaving operations in the case of the 9-11 terrorist attacks. In respond to the Haiti Earthquake, spatial information of the geographic area was not sufficient to support the search and rescue operations in the early phase of disaster response. However, with the help of civilians, information such as road names, infrastructure damage, and victim locations were updated into the spatial data repository. At the same time, resource outside of the disaster affected zone converges into the area to assist the response efforts, which is the effect of convergence that often made resource coordination challenging in large scale disasters. To efficiently collect information and utilize the converging resources, this paper proposes a flexible data repository for information update for equipment utilization in large scale disaster response scenarios.

The Roads in Gangwon Province generally was made on purpose to use the military road. In case of these roads, tremendous dangerous cut slopes do exist and its road linear shape was badly designed. In order to make up for this situation, the government has continuously established the new road or performed the public works such as the straight line of the curved road. Soksil 2 cut slope was made through the road improvement work. This has small surface failures and collapses. In spite of dry season, this slope are leaking lots of groundwater at the unbelievable point. So as to get curious phenomenon right, we performed a detailed field investigation, the geomorphological analysis, the stability analysis considering field characteristic and ultimately proposed the countermeasure to make sure stability of Sokil 2 cut slope.

Collapse of cut slope includes many uncertainties in view of the reason and time. So, in the past, risky cut slopes have been dealt after they've been collapsed through post-management measures. But recently, advanced disaster prevention system is required, and as a part of that RTMS(Real-Time Monitoring System) was developed. In this study, stability of risky cut slope was evaluated by site investigation. To grasp deformation behavior characteristics of slope, numerical analysis based on FEM was performed and using results of that, specific standards for installation of Real-Time Monitoring System were suggested.

In the past, MSW (Municipal Solid Waste) disposal was typically done by recycling, incineration, or landfilling. In South Korea prior to the late 1950's, land burial was usually accomplished by disposal in an open dump. Currently, with increasing concerns and environmental recognition, MSW disposal and landfilling is more restricted. MSW landfill facilities have been developed with certain design and construction specifications. However, these methods have a space for improvement. MSW landfill facilities follow a step wise approach of design, construction, operation and closure management after use in agreement with established environmental and sanitary standards. This study intends to give a technical guidance for installation and consideration of newly established MSW landfill facilities, and also provide an establishment and regular inspection of MSW landfill facilities.

Recently, the Ministry of Employment and Labor Management is a trend to strengthen all men death rate than the accident rate. Points reduction in the accident rate change orders related to credit rating score to +2 points in his plans as part of +1 point. In addition, according to the fancy linger RISK treatment in the event of a disaster site and fiction treatment to achieve accident-free during processing the scene interspersed with equity issues have been raised. In general disaster for the problem in the first two cases occurs when abnormal process according to the disaster site manager positions dismissal policy, each division headquarters itself, interspersed disasters performance compared to processing in accordance with the refrain, processing expenses in accordance with the composition of untreated industrial accident, costs and burdens partners FTC, there is a possibility that the issues raised, such as the Ministry of Employment and Labor. In response to domestic social practices focused on the construction site practices and prevention measures should be evaluated with respect to what.

We have developed inventory database program which is available in the mobile PC. The mobile PC is convenient in terms of portability, data input, modification, practicality of various program and data confirmation in site. By utilizing the inventory database program in mobile PC, we are able to complete database in site. Then, database is converted into the Hangul document and Excel worksheet. Also, based on the above procedure, effective management and utilization of inventory on cut-slope can be achieved.
