  • 본 연구는 민간 회전익항공기 사고의 80% 이상이 조종과실이라는 사실과는 대조적으로, 모든 국내 회전익항공기 조종사들은 군에서 많은 경험을 가지고 민간 분야에서 종사한다는 점에서 어떤 특정한 환경적 요인이 있을 것이라는 명제를 바탕으로 연구를 시작하게 되었다. 우리는 지난 10년간 총 14건의 민간 회전익 항공기 사고가 있었다. 그중 9건 (64%)이 항공기 외부에 인양물을 매달은 채로 사고가 발생했다는 사실과 국내 외부인양물에 대한 구체적인 훈련 규정이 없다는 점을 반영하여, 우선 조종사 외부 인양물 훈련에 대한 국내외 훈련 및 자격 부여 과정을 비교 분석하였다. 그리고 조종사 훈련과 관련된 미국 연방항공청 (FAA) 파트 133 규정인 회전익 항공기(헬리콥터)를 이용한 외부화물 운송관련 법률과 국내 법률을 비교 분석하여 시사점을 도출하여 국내 상황을 적합한 외부인양물에 대한 조종사 훈련과 자격부여에 대한 대안을 제시하고자 하였다.

  • In the event of continued train operation being impossible as the result of a breakdown, it will be essential to dispatch a relief train to recover the broken down train. Operation of relief train carries with the risk of collision in the process of connection with broken down train. The present study looks at the suitability of risk management procedures and associated problems in the light of case studies of relief train operation, and of national legal standards and railroad company regulations. It looks at appropriate methods of risk management and the problems that can arise. Based on the study a method is proposed of operating the relief train which is consistent with appropriate risk management. The proposed method will improve the safety of relief train operation, It is hoped that the results of the study will be reflected in relevant laws and operating company regulations, and so contribute to enhancing the overall level of railroad safety.

  • 항행안전시설은 유선통신, 무선통신, 인공위성, 불빛, 색채 또는 전파를 이용하여 항공기의 항행을 돕기 위한 시설로 악기상 상태에서도 항공기가 안전하게 운항할 수 있도록 각종 정보를 제공하는 시설이다. 항행안전시설은 항공기 운항의 모든 과정에서 이용되는 시설이며, 동 시설에 문제가 발생하는 경우 항공기 운항의 지연, 결항 발생 및 대형 항공사고로 이어져 막대한 인명과 재산피해를 불러올 수 있다. 항행안전시설 관리운영에 있어 안전문화에 대한 안전성숙도에 따라 여러 가지 성과를 가져오게 될 것이다. 본 연구의 목적은 항행안전시설의 관리 운영에 있어 안전문화에 대한 안전성숙도가 조직원 성과, 고객 성과 및 사회적 성과 등의 운영성과에 미치는 영향을 조사하는 것이다. 구조 방정식 모델을 이용하여 분석 결과를 제시하였으며, 그 의미는 결론에 제시하였다.

  • Maritime transport is dominant in the overall volume of all international transportation. Existence and overcoming of problems, which cause pressure on shipping safety, remain actual and fully concern both maritime and inland transport. Increasing speed and cargo capacity of the ships along with the reduction of crew members lead to the automation of a growing number of work processes, which indicates the need to actively introduce appropriate measures in the security system of sea-going ships and commercial ports and to develop modern approaches to minimize negative events and incidents in the process of ship operation. Advantages in use of modern methods of monitoring the safety of ship operations, management of possible events and incidents, including investigation of accidents, first, aimed at prevention of negative occurrences and ways of prevention on this basis. Considering statistics on incidents increase, this work presents analysis of general ship accident rate, study of major accidental events growth annually, and investigation of causes of incidents, which most frequently occur in port waters and at open sea. A survey of current approaches to ensuring the safety of shipping by implementing effective tools, such as event and incident management, has been conducted.

  • LOSA(line operation safety audit)는 정상적인 운항 상태에서 운항 승무원이 발생할 수 있는 사고를 수집하기 위한 선제적 데이터 수집 방식으로 비행 중 발생하는 TEM(threat error management)과 CRM(crew resource management) 등을 수집하는 안전관리프로그램이다. 기존의 LOSA 기록 방식은 워크시트(worksheet) 에 관찰자가 직접 작성하여 자료를 보관하고 관리를 수행하였으나, 자료 보관의 어려움과 비밀 보장이 어려운 문제점이 있다. 기존의 LOSA 수집방식 대신 웹(web) 형태로 한국형 LOSA(K-LOSA)를 구현과 TEM 분류 코드를 변경하므로 효과적인 자료 관리 및 비밀 보장성을 확보하였다. 본 논문에서는 LOSA에 대하여 살펴보고 K-LOSA 프로그램의 구성을 소개한다.

  • Gondola is widely used as a construction facility to perform external finishing work without using scaffolding at a construction site. However, since 2000, there have been 17 deaths from now so these risks associated with work can not be ignored. Therefore, it is expected that it will contribute greatly to prevent related disasters if introducing necessary measures to prevent repeated related disasters and installing additional safety devices. In order to eliminate the risk factor according to the operation of the gondola, it is necessary for the operator to use it to use it while the examination of each product is completed, and to use the over load Dangerous arbitrary measures such as arbitrary operation of the prevention device, removal of the safety fence for convenience of work, installation of the wire rope installed in the air, falling out of the wire rope and falling to the ground Do not perform such sealing measures so that any operation of the overload prevention device can not be done so as not to take such arbitrary measures, or wire the power supply wire to the safety fence so as not to delete the safety fence. Then, when the safety fence is removed, so that it does not become a gondola operation, or when replacing the wire rope in the air, to prevent the wire rope from coming off, Additional measures such as installing falling down prevention device may be necessary.

  • Urban transit operation is to manipulate the vehicle or train of urban transit to be operated on the basis of the installations such as track, power, communication, signaling and so on. It can be performed by manual or automated, or manned or manless operation considering its system built, operation efficiency, safety, etc. Because of the heavy impact directly to the safety of passenger transport, it has been managed strictly by the Regulation for Train Operation of Urban Transit according to Urban Transit Act. However, the present regulation has been basis of the manual operation mainly, it is crossing beyond the limitation of application to the manless operation which is being introduced moment to moment. It is needed increasingly to revise the regulation for the manless operation which is close at hand now. In this paper, we examined and analysed the cases of manless operation of urban transit planed within the country such as Busan 4th Line, Shinbundang Line, Busan-Kimhae Line, etc. based on the present regulation, and proposed the review of considerations to reflec the manless operation to the regulation to be revised.

  • There are a close relationship between natural disasters and train safety. So it is very important to guaranty train safety using reasonable rail-transport operation control against disasters. Therefore, based on the past record of rainfall at failure, rail-transport operation control for railway embankment under rainfall was set up. After slope check list at home and abroad had been analyzed, new slope check list was suggested and site investigations were carried out using this check list. In order to evaluate the stability of railway slopes under rainfall, explanatory variables and subordinate variables were selected for multi-variate analysis and critical rainfall was defined by statistical process. Rail-transport operation control including regional and geological properties was suggested by analyzing the critical rainfall and rail-transport operation control in other country, and this will be a good tool to control train speed under rainfall and to secure train safety.
