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.
Unlike accidents on land, marine accidents can not be supported rapidly from the outside. For this reason, The initial response and damage control system are critical. Cruise Lines International Association (CLIA) reported the necessity of the damage control system to IMO in the early 2000s. Even though the installation of these systems is not compulsory, the damage control system is installed and operated in about 60 cruises. The key component of damage control system is supporting the decision-making using 'KILL Card'. The purpose of study is to develop the shipboard training scenario for the foundation of 'KILL Card'. We made scenarios for fire and flooding through the analysis on existing scenarios, marine accident case and relative regulation. The suggested shipboard training scenario based on damage control system enables the crew to response with rapid decision-making to damage in emergency situations.
In the blast work inevitably exists a vacant space between drilling hole wall and explosive. So it cause an blast inefficiency called on a decoupling effect. In this study, For enhancing the detonation efficiency and reducing the environmental problem(vibration, noise, etc.), water is used to fill the vacant space. Water filling has many advantages such as efficiency, low price and workability. In the comparison analysis the field test is carried out. It result on an aspect of the effectiveness and safety. The result measured in the field is as follows; First, the water tube blast reduces the vibration by 16.5% and lessen the noise by 1% comparing to general blast. Secondly, water tube blast makes a separation distance shortened by maximum 15m. Thirdly, in the case that the same quantities of explosive are used, the amount of crushing per hole increased by about 12.8% in water blast method. The quantity of the explosive is reduced by about 11.4% comparing with general blast.
연구는 산업현장에서 발생하고 있는 중대재해를 줄이기 위해서 시행되었으며 특 히 재해 발생이 두드러지는 소규모 영세사업장을 위주로 작성하게 되었다. 소규모 현장 의 사업주는 근로자에게 개인보호구를 지급하지 않는 경우가 많아 개인보호구를 착용 하지 않고 작업장에서 작업을 하게 되고 자연스럽게 재해로 노출되고 있는 실정이다. 본 연구에서 실질적인 개인보호구 지급 방법에 대한 방안을 제시할 것이며, 기존의 산 업안전보건법상 사업주의 개인보호구 지급 기준에 대한 개정을 주장하여 재해율을 줄 이는 데 이바지하고자 한다. 근로자는 개인보호구를 스스로 구입하여 착용을 해야 하 며, 정부는 근로자의 자발적 개인보호구 구매에 대한 보상으로 퇴직공제부금을 인상하 여 주어야 하고, 사업주에게 산재보험료를 인상하여 적용, 징수하고 이 산재보험료를 통해 근로복지공단에서 개인보호구를 근로자에게 지급하는 방안을 모색해야 할 것이다.
