국내 기반시설의 대부분은 1970년대 경제성장기에 건설되어 사용연수가 30년 이상 경과하였고 급격한 고령화가 진행 중이다. 1990년대 성수대교와 삼풍백화점의 붕괴는 시설물 유지관리의 중요성에 대한 전국민적 관심을 집중시켰고, 이에 정부는 1995년 「시설물의 안전관리에 관한 특별법」 제정을 시작으로 현재까지 다양한 정책 및 기준을 수립해왔다. 일반적으로 안전점검 및 정밀안전진단 등을 수행하여 시설물의 안전등급을 평가하고 결함에 대한 보수·보강을 실시하여 시설물을 유지·관리하고 있다. 그러나 유지관리 예산은 한정적이기 때문에 모든 결함에 대한 보수·보강 사업을 실시할 수 없는 실정이다. 이에 보수·보강 조치의 우선순위를 선정하는 것이 필요하며, 관련 법령 세부지침에는 부재의 중요도, 결함의 심각성, 경제성을 고려한 우선순위지수(PI, Priority Index)를 제시하고 있다. 이 식은 전문가의 주관적인 판단에 의해 영향도를 50~100%범위 안에서 조정할 수 있으며, 일부 특정 부재는 동일한 가중치가 설정되어 있다. 또한 결정적으로 보수보강을 통한 효과를 효율적으로 고려하지 못하고, 대부분 경제성에 의해 우선순위가 결정되는 한계점이 발생한다. 따라서, 본 연구에서는 몇 가지 사례분석을 통해 현재 우선순위지수에 대한 문제점을 고찰하고 이를 개선할 수 있는 우선순위 산정식(PI)을 제시하였다. 과거 유지관리 시행 초기에는 보수보강 사례가 부족하였지만 현재는 수십년간의 축적된 자료를 바탕으로 제시된 산정식을 충분히 활용할 수 있을 것으로 판단된다. 향후 보수보강 효과를 정량화하는 방법에 대한 추가적인 연구가 수행된다면 더욱 경제적인 측면에서 우선순위를 산정할 수 있을 것이며 노후화된 기반시설 유지관리방안에 효과적으로 사용될 것으로 기대된다.

As the variety and scale of facilities increase due to industrialization and urbanization, blind spots for facility safety management have occurred, resulting in numerous casualties.To meet safety and security needs of citizens living in smart cities, we present a procedure for establishing an integrated platform for facility safety management by combining 5G and digital twin technologies. It can be used to perform inspection according to risk factors and aging of facilities. In this paper, the current status of facility management and application directions of new 5G digital twin-based smart city technologies are reviewed and digital twin implementation procedures are presented. Five cities were selected as target areas: Osan, Gwangmyeong, Guri, Uijeongbu, and Anyang. Old and emergency facilities of each local government were selected. A total of 33 digital twin facilities reflecting policy directions of each city were selected. Focusing on facilities determined by each city, the purpose of this study was to define information technology infrastructure elements for the application of the 5G digital twin facility safety management integrated platform, define categories of implementation services, and suggest a concrete integrated platform configuration plan.

This study suggests a solution regarding the effects of apartment facility maintenance and fire safety facility maintenance on the residential satisfaction of residents. The results are as follows. Firstly, facility maintenance had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more breakdowns there were in the facilities. This revealed that when maintenance staff neglect the residents' complaints due to the repetitive aspect of their jobs, there was a negative effect on residential satisfaction; therefore, residential satisfaction must be increased by maintaining the facilities well and training support for maintenance staff. Secondly, fire safety facilities had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more malfunctions there were in the fire safety facilities and the more replacements there were in fire fighting equipment. This revealed the importance of safety and the fact that the apartment heavily relies on fire safety facilities because there may be a low awareness regarding safety; therefore, maintenance staff must lower the damage from fire safety facilities and to increase the residential satisafaction of residents. Lastly, there needs to be repetitive training and education for residents regarding fire fighting and evacuating in accordance with the fire fighting plan as a means to strengthen residents' safety awareness.

This Study is U-City based facilities analysis procedures and techniques of the effective management. We analyze the existing procedure of the management of urban based facilities. And U-City based facilities of management procedures were presented. U-City based facilities were classified regular inspection, safety inspection, emergency inspection, accurate safety diagnosis, routine work and emergency work. We analyze the skills required in the management of these facilities. The procedures for the management of U-City based facilities will improve efficiency of urban management and safety of citizen. As a result, the management of U-City based facilities will lead to improving the quality of services for citizens and competitiveness of the city. Furthermore, this will be the foundation of the environment that people can enjoy safe and convenient life.

안전점검결과 취약시설물 대부분이 정밀점검을 통하여 판단되었으므로, 향후 연차적으로 정밀점검 대상항의 확대 추진과 주기적인 저밀안전진단 실시방안도 검토되어야 할 것이다.아울러, 자연재해로부터 어민의 생명과 재산을 안전하게 보호하기 위해 보다 더 체계적이고 과학적인 안전유지관리시스템과 첨단장비도 점차 마련되어야 할 것이다.

The Special Act on Safety Control for Infrastructure was enacted in 1995 to contribute to ensuring the public safety and welfare improvement of Korean people. In addition, the FMS has been developed and operated to manage facilities effectively. However, several problems of the FMS have also occurred. Thus, this study aimed to analyze the FMS and related systems scrutinizingly to suggest improvement directions such as (1) extension of the FMS into the national facility information management system including small-size facilities other than Types 1 and 2 facilities, (2) development and promote standardized inspection and diagnosis systems as per facility type, (3) development of the database utilization system including decision making support function for management body, and (4) providing the FMS performance improvements and stable operating environment utilizing latest information technologies. If the improvement directions suggested in this study are adopted, they can improve services for Korean people by providing facility safety and maintenance work parties with optimum information services.

지하공간은 지하철, 지하도, 지하상가 등 이미 생활의 일부로서 많은 시민들이 이용하고 있다. 최근에는 지하공간의 이용이 더욱 복잡해지고 대형화 되면서 안전에 대한 우려가 커지고 있다. 복합적인 이용공간으로 자리매김하였으나 지하공간의 관리와 지하공간에 대한 관련법 등은 아직까지 지상의 시설물들을 기준으로 한 지하공간의 특성을 반영하지 못한채 머물러 있다. 본 연구에서는 이러한 문제점을 진단하기 위하여 지하공간의 안전한 관리를 위해 관련 법령들을 고찰하여 문제점을 분석하였다.

Main infrastructures, such as levee, dam, bridge, road, etc., are very important due to not only the means of support for social and industrial activities in normal situation but also the means of protection of life and property during disaster occurrence. In spite of this importance of infrastructures, however, any disaster management systems that actively use these infrastructures are not developed yet. Moreover, infrastructures are not usually included in emergency action plans, thus it occurs second and third impact on communities and industries due to collapsing or damage of infrastructures. Therefore, the authors in this paper analyzed previous research, SWOT, STEEP, and patents and technical journals and conducted a technology need survey ni order to understand the trend of disaster management system as well as suggest main research fields and detail research items. The results of this paper will be a foundation of developing an advanced infrastructure integrated system of maintenance and disaster mitigation and contribute our nation to have an active response system by using infrastructure.

본 연구는 건설된 구조물의 주요 구조부재에 각종 계측 Sensor를 설치하여 이로부터 다양한 정보를 제공받아 Monitoring하는 계측 System은 대형구조물의 구조적 응답을 계측하여 분석하고, 구조물의 위험요소를 사전에 발견하고 분석하여 적절한 대책을 수립함으로써 대형 시설물의 수명연장 및 유지관리 비용의 효율성을 높이고, 구조물의 사용성 및 안전성을 확보하고, 그 설계수명을 유지할 수 있는 것이다. 계측전 초기치와의 비교 및 시간 경과에 따른 추이 분석을 통해 이상상태를 발견하는 신호 기반 감시 수행하고 있고, 상태판정 및 손상도 추정이 가능하므로 향후 계속해서 발전시켜 나갈 수 있는 지식기반 감시시스템이 필요하므로 본 연구에서는 공간 정보기반의 정보를 재생하여 GNSS/USN기술을 접목시켜감으로 대형시설물 안전관리가 매우 용이하게 적용할 수 있도록 하였다.
