Efficiency and efficient management on maintenance/repair/operation (MRO) phase is getting important with advance in technologies and complex functionalities of building and facility, Using software systems as well as advanced hardware systems in MRO area is spreading along with this trend to take advantage of information technology. Information of building and facility for MRO phase is derived from engineering/procurement/construction (EPC) phase. But most current commercial software systems in EPC and MRO are focusing on their own phase, which arise lack of consistency of information from EPC to MRO phase. But, the information system now used at the MRO phase stop flowing the building and the facilities information and then newly create. Moreover, from an asset management point of view, asset particulars such as the structures and equipments are different the value fluctuation. In order to reflect these information rationally, the construction costs are correctly distributed and the initial price of the asset particulars have to be estimated. In this study, develop the information model which can apply the cost information at the EPC phase to the MRO phase.

There have been arguments in Korea that fair value accounting system improves quality of accounting information through the asset revaluation. These arguments are based on the fact that investors prefer fair value to cost value information. Others argue that cost principles may offer more proper information to the investors because financial statements applied the cost principles are more objective and thus more reliable. Prior researches focused mainly on the motives of asset revaluation but I examined the effects of the tangible asset revaluation on the stock prices. The empirical findings indicate that : (1) the gains on the tangible asset revaluation are positively correlated with the stock prices; (2) the net book values applied the cost principles explain stock prices better than the net book values applied fair values. My findings suggest that the gains on the tangible asset revaluation constitute a part of the firms' values but the accounting informations measured fair value are not always useful to the investors in the capital market.

Road pavement management is an important activity that affects to national economy, movement and safety of people, and also demands huge amount of budget. Therefore, its management strategy must be established under objective information. In addition, decision support system that produces the management strategy needs to consider practical benefits from various aspects. Considering these aspects, this paper aimed to develop a customized Korean life cycle cost analysis model estimating various effects on road users and socio-environmental costs based on pavement condition. The suggested LCCA model focused on Korean national highway, and tried to adopt a national guideline recommended by Korean government for securing credibility of estimation results. In the development processes, some of the suggestions that do not fit well in the situations of pavement management field were added, altered, or partially modified. These attempts to develop customized asset management system would be an important step to break away from passive attitudes relying on ready-made software, but also to improve awareness about the social benefits from the better maintenance strategy.

Digital assets denote multimedia information that exists in the form of digitized materials such as images, audio, and video. The management of digital assets demands much effort because of a huge amount of storage space requirement and multidimensional characteristics of the information needed to describe their contents. In this paper, we design and implement a Digital Asset Manager that stores and manages digital assets efficiently. Among the various types of digital assets, we focus on the video asset which has the highest complexity. Our Digital Asset Manager provides various facilities for digital contents authoring applications. In the Digital Asset Manager, video assets are managed by using a hierarchical model in order to ensure efficient accesses to any part of a video asset. Our system also guarantees the independence from the storage platform, and provides a fast content-based similarity search method on the digital assets.

This study focuses on the management of the news production system in broadcasting companies. This paper concentrates on the process of data registration and metadata management in order to examine whether the currently produced news can have value as a 'public record' in the long term, and whether reliable and accurate information is preserved. In addition, the user experience in the current system is analyzed through in-depth interviews with Ingest Managers, Editors, and Archive Managers, who are closely related to metadata creation compared to other members of the its News Department. Finally, a sustainable metadata quality management method is sought to increase the value of news footage as a 'public record'. In this study, these points can be found out: the metadata of the news agency footage is input manually according to the user's will or working style, that is, the user-friendly metadata input system is insufficient. Accordingly, it can be seen that the quality of the metadata of the news video continues to deteriorate. As an alternative to overcome this, it is found that work flow improvement, system improvement, classification system and metadata improvement plan, etc. are definitely necessary in the short and long term.

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.

Social network service user or smart phone user is very convenient, because there are supported to various social network services such as Facebook, Twitter, Flickr, Naver blog, Daum blog, and so on. This Is very good because they store multimedia datas that user wants to cyber space if they want it conveniently. But, if social network user increases, space of cloud storage increases sharply, and when social network service used user dies then they have big problems such as they did not know in existing. Typically, problems of notice, dissemination, storage, and inheritance for digital asset can happen representatively. Now, If successor send relation information of he and his dead user that is family to social network service provider then service provider checks it. And successor may can use, save and only backup are possible after confirm of family relation truth. Therefore, We wish to propose ADAM that successor may can inherit digital assets easily, conveniently, and safely in this paper. If someone use ADAM, successor submits information about dead and own family relation in the third certification party. And ADAM can be inherited freely and conveniently about digital assets as general assets passing through right inheritance process.

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.
