Electric shutters for buildings are being developed in Korea and abroad on a regular basis and can be used in different types of buildings such as company buildings and fire stations, etc. However, the fall risk factors induced by a variety of functions of building electric shutters require safety control. We reviewed the technological trends and legal standards in Korea and abroad, analyzed incident cases, and identified fall risk factors requiring control. We inspected all the building electric shutters in Korea based on the fall risk factors. As a result, we identified 91 noncompliance cases, in 69 percent of all 132 locations. In this study, backed by the inspection results, we suggest a check list to prevent the fall of building electric shutters to ensure safety and conduct verification using a focus group interview.

This study shows the difference between groups with multivariate analysis of fire prevention activities, special investigations of fire safety, and fire safety management according to the management method of apartment houses and the inspection of firefighting facilities. The results of the analysis are as follows. First, there was a significant difference in fire prevention activities according to the quality of inspection of firefighting facilities. This means that fire prevention is high if the fire safety manager's ability to inspect firefighting facilities is excellent and the fire safety inspection is conducted in accordance with national fire safety standards and checklists. Second, there was a significant difference in the fire safety special investigation according to the management method of the apartment buildings. The manual operated by the management entity and the management entity's management and execution help the organization members to expedite work. This expedition of work creates a high possiblity to get a good evaluation from the special investigation of fire safety. Third, analysis of fire prevention activities showed a significant interaction between the inspection of firefighting facilities and the management method of apartment buildings. The analysis shows that that there is a positive correlation between the level of fire prevention and both the fire safety manager's ability to inspect firefighting facilities and the degree to which the inspection is conducted to meet national fire safety standards.

Safety inspections of outdoor advertisements are conducted to determine the aging status, specifications, and compliance with design documents. Regular inspections are conducted on outdoor advertisements from a safety perspective, as they not only undermine the aesthetic elements of the city but also could cause falls on roads or pedestrian paths. However, the current safety inspection methods are at risk of various accidents during the inspection advertisements on the outer wall of the building. And it is difficult to conduct in-depth inspections on them if they are fixed to the elevation of the building. Furthermore, there also is a risk of safety accidents, such as advertising structures falling onto a pedestrian path. Therefore, this paper aims to enhance the safety inspection system of outdoor advertisements using drones. This paper also intends to propose measures for facility inspection history management such as safety inspection cycle, maintenance, and removal of signboards.

In the case of precise safety inspection and precise safety diagnosis of a building, a condition evaluation must be conducted to determine the safety grade. Since 2004, an evaluation method using fuzzy theory has been introduced for quantitative condition evaluation,and the relationship and importance of reinforced concrete members using fuzzy theory have been applied. Generally, fuzzy theory is a method used to deal with ambiguous expressions with unclear correlations, but at the time of development, it seems that it was developed by applying fuzzy theory as an alternative in a situation where inspection and diagnosis result data were insufficient. Therefore, it is necessary to verify the relationship and importance of evaluation items derived based on the current fuzzy theory using actual inspection and diagnosis result data.In this study, the correlation between the evaluation items was derived by using the results of 19 precision safety inspections and 9 precision safety inspections and the performance score function formula, and using this, a reasonable durability score calculation formula of the member was presented.

Purpose: The study is based on comparative review of the actual inspection of apartments and aims at proposing easy accessible and useful safety control which is enhanced from pre-existing safety apparatus. Method: On the basis of preceding research data of apartment buildings, the study presents reported problems and real condition of apartment buildings based on Housing Related Legislation and Housing Act. Results: Safety management plans and safety inspection for buildings are needed. When conducting a safety check, traceability management system for internal/exterior facilities should be available. Most important of all, 24 hour a day of self-management system for elevators, fire protection, and security cameras is necessary. Conclusion: Through the study, there should be a process of confirming problems of building security management; such as checking the management condition through apartments' resident representatives, and seeking improvement measures.

우리회는 한국기술사회건축구조분회로 출발하여 2년 전 유병억 회장님시절 개인사업자등록증을 발급받아 구조분회가 아닌 개인 사업체로서 한걸음 진일보하였다가 작년에야 비로서 우리의 숙원이었던 과학기술부 산하 사단법인체로 등록되면서 명실공히 사단법인 한국건축구조기술사회로 위상을 한단계 격상함으로서 합법적으로 정부로부터 인가받은 단체로 발돋음하였다. 그동안 건축구조안전에 대한 문제점을 알고 있었으나, 정부와의 어떠한 합법적이고 독립적인 통로가 없어 제대로된 의견개진을 할 수 없었던 상황에서 이제는 올바른 통로를 확보한 첫 걸음이라고 판단된다. 아직도 우리가 헤쳐나아가야 할 길은 멀고도 험난한 상황임을 잊지말고 끈기있는 인내심과 중단없는 전진을 통해 하나씩 건축물의 구조안전을 확보하기 위한 방안을 위해 지속적으로 노력을 하였으면 한다. 올해 2월 정기총회를 통해 사단법인으로 처음 출발하면서 이동헌회장님을 비롯한 신임회장단이 선출되었고, 그 장도의 첫발을 내딛으면서 앞으로 우리가 어떤 목표를 견지하여야 할 것인가에 대해 의식고취 및 앞으로의 방향설정을 위해 지난해 3월 건설교통부에서 발족한 건설교통안전기획단의 검토 내용에서 발췌한 현행 실태와 문제점 및 대책 중에서 건축물의 구조안전과 관련된 문제점을 다시 한번 되새기면서 우리의 목표와 방향을 점검하는 계기가 되었으면 한다.

Recently, interest in the safety and maintenance of the structures is growing. However, due to the low-cost order placed by the ordering organization, the safety diagnosis specialized institution becomes insolvent and many problems have arisen due to insufficient inspection and diagnosis. Therefore, in this study, the current status of bid cost was examined through the survey of the practitioners and case analysis. As a result, Precision safety inspection is deemed that it is necessary to increase the efficiency of the criteria cost and to strengthen the rigidity of the criteria cost rather than adjusting the criteria cost. Precision safety diagnosis, the criteria cost for structures with a floor area of less than $10,000m^2$ is lowered to 80 % from the current standard. For structures larger than that, the current criteria cost are applied, but it is deemed necessary to strengthen the rigidity of the criteria cost.

In this study, an algorithm was developed to validate the seismic acceleration measurement data of the seismic acceleration measurement system using measurement data from public buildings currently in operation. Through the results of the study, an algorithm was developed to detect errors and abnormalities in the measurement data itself and the process of generating real-time data (MMA/sec) and event measurement data (MiniSEED), which are the main data generated by the system, and the basic data for determining the direction of inspection through measurement data analysis. It is expected that this will be used as a guideline to determine whether or not the seismic acceleration measurement system, which was managed as receiving/not receiving, is inspected and abnormal types of conditions.

소수력발전소가 건설 후 점검 및 유지보수를 지속적으로 수행 설비성능을 유지하지만, 30년이 경과하면 노후화 및 피로현상으로 성능이 저하되고 경제적 내용연수가 도래한다. 대수력의 경우 전문인력과 점검 및 보수비용을 투자하여 일상, 주간, 월간, 년간, 정기보수를 수행하고 그 기록을 유지관리하고 있지만, 소수력발전소의 경우는 그러하지 못하여 발전소 효율뿐만 아니라 운용중의 안전도 위협받고 있는 상황이다. 본 논문에서는 국내 시설물 안전관리에 관한 특별법에 의거 필리핀에 위치한 노후 수력발전소의 현대화를 위하여 최초 기존 시설물에 대한 안전진단을 실시하여 토목 및 건축물의 보강을 위한 방법을 선정하고 이를 바탕으로 수력발전설비로부터 발생하는 진동과 같은 다양한 영향을 감소시키기 위한 토목기술을 반영하여 현지 환경에 적합한 수차선정과 노후 시설물의 유지보수를 국내 토목 보수 보강 기술로 설계하였다.
