Therefore, it is necessary to establish and revitalize regulations related to building diagnosis and maintenance management, to revise the laws and regulations of related institutions, and to systematically cultivate manpower through specialized agencies related to diagnosis and maintenance.

부산항 ‘A’ 터미널에서 발생한 지난 3년간의 사고 데이터를 분석하여 어떤 장비가 가장 많이 사고를 발생하였고 어떤 위험점이 가장 높은지를 위험성 평가기법으로 알아보고, 이러한 사고를 미연에 방지하기 위한 방안을 보우타이 기법을 활용하여 제시하고자 한다. 실증자 료를 분석한 결과 터미널 내의 이동장비 중 야드 트랙터의 충돌사고가 가장 높은 것으로 나타났다. 안전한 부산항을 만들기 위하여 우리는 가장 먼저 야드 트랙터의 충돌사고 예방법 (Control measure)과 사고 발생 시 대처방안 (Recovery measure)을 철저히 준비하여 사고를 미연 에 방지하여야 할 것이다. 본 연구의 결과는 관련 실무에 다양한 시사점을 제공하였다.

본 연구는 병원 및 대학교 등에 설치된 X선 발생장치를 대상으로 진단용 방사선 발생장치의 품질관리 항목을 적용하여 성능 비교를 하여 주기적인 성능관리의 중요성을 인식시켜 성능유지 및 관리에 도움을 주고자 한다. 우선 재현성 및 직선성 실험결과 모든 실험조건에서 합격기준에 부합되었으며 주기적인 정도관리가 부족한 GX-650장치의 경우 재현성 평가의 백분율 오차가 높았으며 직선성 평가에서는 관전압을 100 kVp로 설정 시 0.105로 백분율 오차에서 벗어나게 측정되었다. 또한 관전압 및 관전류의 정확도 평가결과 상대적으로 X선 발생횟수가 낮은 장치에서 백분율 오차가 낮은 것을 알 수 있었다. 반가층 실험은 모든 장치에서 관전압 별 반가층 기준에 모두 포함되었다. 따라서 병원용, 실습용 구분보다는 모든 장치의 정도관리의 중요성을 인식하고 적극적으로 장치의 성능관리를 시행하여 장치를 유지 관리해야 할 것이며 특수의료장비처럼 짧은 주기의 정도관리 제도를 마련해야 할 것으로 사료된다.

Engineered nanomaterials (ENMs) can be released to humans and the environment through the generation of waste containing engineered nanomaterials (WCNMs) and the use and disposal of nano-products. Nanoparticles can also be introduced intentionally or unintentionally into waste streams. This study examined WCNMs in domestic industries, and target nanomaterials, such as silicon dioxide, titanium oxide, zinc oxide, nano silver, and carbon nanotubes (CNTs), were selected. We tested 48 samples, such as dust, sludge, ash, and by-products from manufacturing facilities and waste treatment facilities. We analyzed leaching and content concentrations for heavy metals and hazardous constituents of the waste. Chemical compositions were also measured by XRD and XRF, and the unique properties of nano-waste were identified by using a particle size distribution analyzer and TEM. The dust and sludge generated from manufacturing facilities and the use of nanomaterials showed higher concentrations of metals such as lead, arsenic, chromium, barium, and zinc. Oiled cloths from facilities using nano silver revealed high concentrations of copper, and the leaching concentrations of copper and lead in fly ash were higher than those in bottom ash. In XRF measurements at the facilities, we detected compounds such as silicon dioxide, sulfur trioxide, calcium oxide, titanium dioxide, and zinc oxide. We found several chemicals such as calcium oxide and silicon dioxide in the bottom ash of waste incinerators.

The number of structures that make up the domestic social infrastructure has increased with the development of the national industry, and the social demand for safety due to the aging of structures has also increased. Accordingly, the law stipulating safety and maintenance management for major structures in the country has been revised and it has been implemented since this year. In this study, we will introduce changes to the safety and maintenance system for public structures under the law, analyze the results of inspection and diagnosis of public structures, and consider the status of safety and maintenance.

Many of the facility management information system are being operated by each government departments and Acts. Therefore, it is difficult to share and integrate data through the network because data standard codes are not established. In spite of these problems, the Special Act on the Safety Management and maintenance imposes duties on the main agent of national infra structure management and the maintenance results should be integrated in Infra Structure Information Management System(FMS). Thus we propose the structure classification standard codes for the FMS to integrate and analyze safety and management data.

The purpose of the safety inspection is to identify the cause of the damage, which is the cause of the safety and performance degradation of the structures, to identify the cause of the damage, and to suggest appropriate repair and strengthening methods. In the traditional safety inspection procedure, the inspection items are selected and the survey contents are recorded in the field book at the time of the field survey. It is not easy to accumulate data and analyze these data as a single project. In this paper, we analyze the problems of the existing facility inspection procedures and conducted studies to build two-way facility safety management system for shortening the processing time and convenience of increasing the efficiency of field work and reporting.

Purpose - In this study, the safety related tasks for low cost carriers’ were examined and measures to improve them were suggested. As the air demand increases rapidly, number of passenger has mushroomed in Korea and in order to keep with the demand low cost carriers have played a role. However, low cost carriers’ safety related tasks are not reliable level so far. Thus, in this study, the low cost carriers’ current situations in terms of safety are investigated, especially regarding how well the ICAO’s new safety policies are applied. Research design, data, and methodology - The results of the Ministry of Land, Infrastructure and Transportation’ investigation are introduced and field study results are analysed. Current status of retaining experts, staffs, administrators in terms of aviation safety tasks of low cost carriers is compared to those of major airliner and low cost carriers’ aviation safety culture is also analyzed by examining the systems and questioning staffs. Especially the culture regarding aviation safety is very important because the culture surrounding the safety tasks plays a major role in every respect of conducting the tasks. Results – Overall the current status of low cost carriers’ aviation safety tasks is below standard. Especially retaining experts and staffs is basically below the required level. Also, system and organization to conduct safety tasks are not satisfactory. In particular, aviation safety culture is not settled to operate appropriately. Conclusions - The International Civil Aviation Organization (ICAO) and member states are continuing to launch new safety policies in response to the surging demand for air travel worldwide. The most urgent and important issue among the various safety policies is to reduce air accidents. In order to reduce the number of accidents, ICAO decided to reduce the number of accidents by using the Reactive Safety Management. ICAO has to ensure that each member country can implement proactive safety management for aviation safety. A safety management system (Safety Management System) is a system in which each member state implements a fulfillment standard. The current situation and problems of the safety management system for each airline are suggested and proposed for improvements.

In spite of importance of safety issues in community sport, little concerns have been paid to the sport safety policy. Governing bodies and individuals involved with the facility management have a responsibility to manage the risks at acceptable levels. For sports injury prevention interventions, the safety policy of sport facilities should be made to provide a structured framework which can be implemented at community sport. Hence, the current study is to identify the safety issues and to generate the policies that assist to conduct the systematic safety management at sports facilities. For this, the current study analyzed two cases from Japan and Germany. The study reviewed multiple pieces of literature including journal publications, political reports, and media coverage. Through review, the study analyzed the organizational structure, legal systems, and political stance of the safety management of sport facilities in Japan and Germany. The results proposed the following issues. First, law needs to be enacted to establish the control tower where has a responsibility to develop the safety manual and system. Second, local organizations need to be established to educate individuals working in sport facilities and inspect the facilities. Further political issues were discussed for safety management in Korea sport facilities.

The Integrated Water Infrastructures Safety Management Platform(WINS+) provides safety information of water infrastructures such as dams, weirs, bridges, cut slopes, retaining walls and levees designated as the first class infrastructures to be maintained according to the nations’s safety law. The WINS+ is incorporated with a computerized Standard Operating Procedure (SOP) system that provides crisis warning level (green/blue/yellow/orange/red) to central and individual disaster response managers of waterside structures. Thus it is expected that by using the WINS+ we may strengthen disaster responsiveness and reduce the time for recovery and response at emergency.

A series of disaster response drill was conducted using a robust and integrated safety management platform (WINS+) which can provide multi-functions of safety evaluation in realtime, disaster information provision and recovery actions for major water infrastructures, which are designated as nation’s first class infrastructures, under natural disasters such as floods or earthquakes. It is believed that the experience of disaster response drills using the new integrated safety management system (WINS+) enhances our capability of preparedness and response against disasters, and that the validity of WINS+ can be clearly confirmed.

Many of the structures constructed since the 1970s have begun to deteriorate. As a result, safety inspection / diagnosis and maintenance are expected to increase further, and long-term and systematic measures are urgently needed to prepare for the aging of major infrastructures. Currently, the safety inspection and maintenance of the structure is carried out by the method based on the utilization of the measurement data and the manager's experience, but the reliability and the accuracy are still insufficient. In other words, there is a limit to understanding the state change of bridges, such as abnormal behavior and gradual damages, therefore, it is necessary to have an accurate and reliable monitoring process using new techniques and systems. For this reason, I would like to examine the possibility of using cloud and big data in the field of infrastructure safety management.
