교통소통과 안전을 위해서는 체계적이고도 획일적인 교통안전시설물의 설치 및 관리가 요구된다. 앞으로 교통안전시설물에 많은 투자가 절실히 요구되며, 계속 늘어나고 있는 자동차등 여러 가지 교통여건을 감안하면, 교통안전시설물에 대한 수요는 더욱 증갛살 것으로 예상된다. 지리정보시스템 (GIS)을 활용하게되면 급증하는 교통안전시설물의 조사 및 유지·관리업무를 제한된 인력과 예산으로 수행할 수 있게된다. 그러므로 교통안전시설물의 체계적인 유지·관리를 위해선 GIS의 활용은 필수적이라 하겠다. 또한 신설 및 교체수량의 정확한 예측 등과 같은 효과를 거둘 수 있어 효율적인 예산을 집행할 수 있게된다. 본 연구는 지리정보시스템 (GIS)을 이용하여 교통안전시설물 유지·관리 시스템 개발에 목적이 있으며, 특히 개발된 시스템은 실무담당자 활용에 편의를 도모하는데 주안점을 두었다.

According to the Framework Act on Sustainable Infrastructure Management, which has been enforced since 2020, reservoirs should be managed to minimize life cycle costs caused by aging through preemptive management such as systematic maintenance and performance improvement. For maintenance in consideration of the life cycle, it is essential to derive the end of life due to continuous performance degradation as the common period increases. For this purpose, it is necessary to develop a performance-predicting model for reservoirs. In this study, a reservoir was divided into main complex facilities to develop a model for the maintenance of the life cycle. A model was developed for each facility. For model development, maintenance information data were collected under management by the Rural Community Corporation. The data available for model development were selected by analyzing the collected data. The developed model was used to predict the expected life expectancy of the reservoir in the current maintenance system and the expected life expectancy in the case of no action. By using the developed model, it is expected that it will be possible to support decision making in operation management and maintenance while considering the life cycle of the reservoir.

In this paper, the preventive maintenance strategy in operation stage of a bridge using Bayesian inference is proposed. The proposed technique can be used to predict the variation in the performance (or condition) of the bridge with higher accuracy, considering the uncertainty of monitoring. The applicability of the proposed method to the existing bridges is verified and analyzed that have an advantage in terms of maintenance cost efficiency compared to the conventional periodic maintenance system, which establishes maintenance after damage. It is expected that the proposed preventive maintenance method can be used to overcome the limitation of the conventional periodic maintenance method and to make practical bridge maintenance decision.

많은 정보시스템이 점차적으로 전산망으로 연결되므로서, 보안성에 대한 위협이 더욱 증대되고 있다. 적절한 보안성을 유지하기 위해서는 시스템이 어느 정도 위험한지를 파악하여 이를 관리하는 노력이 필요하다. 이와 같은 노력의 가장 중심이 되는 것은 위험관리의 체계를 세우고 이에 따른 방법론을 개발하는 것이다. 본 논문은 기존의 위험관리 체계를 검토하고 분석하여, 이를 기초로 단순하면서도 실용적인 위험관리의 체계를 제시하고자 한다.

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.

Recently, the rapid proliferation, introduction, and application of the fourth industrial revolution technology has emerged as a trend in the construction market. Building Information Model (BIM) technology is a multidimensional information system that forms the basis of the fourth industrial revolution technology. The river sector utilizing this information-based system is also being actively reviewed, for example, the current measures for maintenance. In recent years, active research and current work should be done to reflect the need for river experts to introduce BIM into the river field. In addition, the development of tools and support software for establishing various information systems is essential for the activation of facility maintenance information systems reflecting advanced technology and to establish and operate management plans. A study on the maintenance of river facilities involves using existing drawings to build a three-dimensional (3D) information model, check the damage utilizing it, and inform it, and utilize it as the data for maintenance reinforcement. This study involved determining a method to build a river facility without the existing information system and using the property maintenance information with 3D modeling to provide a more effective and highly utilized management plan to check maintenance operations and manage damages.

This paper proposes a classification model for systematical management of resources in educational repositories. A classification scheme should be provided to systematically store and manage, precisely retrieve, and maximize the usability of the resources. However, there is little research result on the classification scheme and classification model for educational repository resources. It causes several issues such as inefficient management of educational resources, incorrect retrieval, and low usability. However, there are different characteristics between the educational resource information and information of the previous fields. Therefore, a novel research on the classification scheme and classification model for the resources in educational repositories is required. To achieve the goal for efficient and easy use of the educational resources, we should manage consistently the resources according to the classification scheme accepting several views. This paper proposes a classification model to systematically manage and increase the usability of the educational resources. In other words, the proposed classification model can manages dynamically the classification scheme for the resources in educational repositories according to various views. To achieve the objectives, we first define a proper classification scheme for the implementation resources based on the classification scheme in relevant scientific technology fields. Especially, we define a novel classification model to dynamically manage the defined classification scheme. The proposed classification scheme and classification model enable more precise and systematic management of implementation resources and also increase the ease of usability.

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.
