In many developed countries, social infrastructure asset management has become an important issue for the effective operation and management, performance improvement, and providing better quality services. This paper describes infrastructure asset management practices in Korea and in the developed countries. Learning lessons from those countries and improve the asset management practices in Korea is the main theme of this paper. Considering the definition and basic structure of infrastructure asset management, authors have analyzed main concerns regarding infrastructure management, techniques, organizations (systems), and processes. The requirements and considerations are presented to overcome the limitations of current maintenance system. This paper will assist adopting infrastructure asset management in Korea and provide guide for the infrastructure maintenance.

Evaluating methods for software asset have been made based on subjective evaluation criteria. In this study, we try to evaluate the usability of complex assets obtained from the previous measurement of the complexity of the asset management system. The evaluation used a scale provided by measuring logical complexity to measure the complexity of the asset, and evaluated the relationship with the usability of the software asset by measuring the index related to reusability. Therefore, it can be seen that HVs maintain a constant ratio according to the composition of various assets for the two types of assets and maintain the applied consistency. Therefore, it can be determined that an asset optimized in terms of usability can be applied consistently in the architectural design process while securing as much diversity as possible.

As many parts of Korea are mountainous, many tunnels have been constructed to be in step with rapid economic development since 1970's. However, the interest on maintenance of tunnels is far less than the awareness of need for tunnels. As the tunnel maintenance system is the responsive maintenance system which responds to the problems found during the inspection, it will be very difficult to respond to each problem with the limited budget and manpower of the government agencies when the number of aged tunnels rapidly increase in the future. As such, this study presents the need for the LCCA (Life Cycle Cost Analysis) based tunnel asset management system to transform the tunnel maintenance to a preventive management system in a strategic and long-term viewpoint and proposes the framework for development direction. It observed the asset management implementation cases of social infrastructure in other countries and analyzed the need for asset management technique to manage the tunnels in Korea. Moreover, it applied the LCCA model, which is the economic and engineering quantitative decision making technique, for tunnel asset management to present the concrete direction for development of an asset management model and designed the R&D framework to systemize it.

Asset valuation of social infrastructure is essential for rational decision-making for efficient management of assets. In addition, it can be an indicator for correctly recognizing assets. In general, Korea applies depreciated replacement cost based on the straight-line method to evaluate asset value, yet this is unsuitable for evaluating actual value because it is depreciated at a constant rate over the useful life period. In order to evaluate the asset value considering the performance of the bridge, the performance index of the bridge is estimated using the Weibull distribution. Using the estimated performance indicators and defect index, a new asset value evaluation method is proposed and compared and analyzed with the existing method. The proposed valuation method can take into account the performance of the bridge, so it is judged to be more objective and reasonable than existing method.

The government policy had placed new construction as the kernel of the investment in the road department. This had been shifted, however, since the government's budget of the road department reached its peak in 2000, new construction had came to a downsizing phase while the maintenance increased gradually. Considering this recent trend, the necessity of a new paradigm in the road policy had came to a fore, in order to prove the justification of increase in the maintenance budget as well as successfully fulfill the user's needs in the service quality. The developed countries that had intensively constructed social infrastructure in 1950-60s are enjoying a great achievement by applying the asset management concept in coping with the deterioration of the public facilities. This research suggests the basic framework in establishing "Korean Road Asset Management System" designed to efficiently manage the national road. The main feature of this system is to absorb economic analysis course into the current pavement management system, in order to form not only long-lasting but also preventive road management policy.

댐의 중요 구성요소 중 하나인 여수로 구조물은 관행적으로 단위길이당 100m³/s 정도의 유량이 흐를 수 있도록 설계를 하고, 이를 초과할 때는 여수로 구조물에 피해가 가지 않도록 공기혼입 장치를 설치하거나 콘크리트의 설계강도를 증가시키는 대책을 사용하는 것이 일반적이다(댐설계 기준·해설, 2011) 그러나 건설된 지 오래된 댐의 경우 여수로 콘크리트 구조물의 설계강도가 낮고(최저 16.7MPa) 수문방류 횟수가 많아 최근에 건설된 댐 여수로 보다 상대적으로 많은 손상이 발생되어 있어 잦은 보수보강이 요구되고, 점차 유지관리 비용이 증대되고 있어 노후된 여수로 구조물일수록 기능을 유지하면서도 유지관리 비용을 절감할 수 있는 방안의 수립이 요구되고 있다. 이에 본 연구에서는 𐩒𐩒𐩒댐 여수로를 대상으로 2020년 홍수기 전·후의 여수로 바닥슬래브의 손상상태를 3D드론 매핑, 육안조사 및 내구성 조사결과 등을 이용한 정밀분석을 통해 수문방류시 여수로 바닥슬래브에 가장 큰 손상을 일으키는 손상메커니즘으로 유수에 의한 부상(uplift)에 의한 파손 메커니즘(Flow-driven uplift failure mechanism)을 제시하였으며, 여수로 바닥슬래브의 가장 일반적 손상원인으로 간주되고 있는 공동현상(cavitation)이 공동지수(cavitation index)가 0.3이상인 경우에도 발생할 수 있음을 확인하였다. 이와 같은 관찰 및 분석결과는 보다 많은 사례를 통하여 보완될 경우 향후 여수로 구조물의 설계 뿐만 아니라 보수보강 방법이나 유지관리, 더나아가서는 종합적 댐시설물 자산관리 계획을 수립하는데 매우 유용한 자산이 될 수 있다.

This paper investigates accounting principles about social infrastructure on Korean National Accounting Standard and on National Accounting Standards from other countries that adopted a accruals- based national accounting standards. Social infrastructure as assets has important value in financial statements of Korea and deterioration or insufficient management of social infrastructure accompanies a huge social cost. Therefore, understanding the characteristics and related accounting standard for social infrastructure is necessary. To do this, we examine the accounting standards of U.S., New Zealand, and Australia. We also review the financial statement of local government. Based on these findings, this paper suggests that a preventive-asset management approach should be applied and alternative depreciation method for social infrastructures is developed. Moreover, a local government needs to provide important accounting information to the public in a timely and reliably manner.

The maintenance management system of domestic public facilities is shifting from the concept of diagnosis and repair for maintaining safety of facilities to performance evaluation method that improves and maintains the performance of facilities. However, in Korea, the performance evaluation method for the maintenance of facilities has not been established, so the performance evaluation has not been properly performed. In this study, we propose an asset management model that introduces the concept of performance evaluation to complement the simple maintenance strategy focused on safety management of current facilities. This model differentiated from the existing model by proposing a method for using WBS as a method for collecting facility maintenance information. This model proposed the most important level of service evaluation method and performance measure factors in the performance evaluation of facilities, and conducted a case analysis to assess the appropriateness of this model.
