        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.

        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.

        Recycling standards and methods of steel slag are prescribed in the “Waste Control Act” and the “Act on the Promotion of Saving and Recycling of Resources”. However, the recycling purposes and methods for non-ferrous slag are permitted for lead, zinc, and aluminum slag, etc., and only small amounts are recycled. Most non-ferrous slags are treated by consigned treatment or landfill. In addition, some non-ferrous slag can cause environmental pollution when directly recycled in soils or result in high costs for disposal or storage due to high heavy metal concentrations. In this study, we investigated the characteristics of slag generated during non-ferrous metal processing or recycling, providing recycling purposes and methods including those for useful metal recovery based on the characteristics of slags, cement and cement additives, and alternatives to natural aggregates. Content analysis of non-ferrous slag showed the concentration of metals such as Al and Cu ranging from 1 to 27%, indicating the necessity to recover the secondary metals by properly grinding slags and using economical concentration technologies. Based on the leaching test result of non-ferrous slag, rainfall blocking facilities need to be installed to prevent rainfall from flowing into storage sites for slags so that alternative materials can be safely managed.
