Generally, asset management procedure consists of exact information collection, decision of service level, analysis of aspiration level, analysis of financial condition and available budget, preparation of asset management plan, and value of modified asset. In this study, for the risk-based asset management, condition assessment and performance measuring, assessment of failure modes and risks, evaluation/selection of treatment options, and implementation of optimum solution are additionally included. For this, bridge inventory and performance measure considering risks are classified and method of quantitative/qualitative performance measure is suggested. Also, evaluation method of risk analysis for bridge asset management is suggested and basic research is carried out for applicable method of risk-based asset management. Using suggested risk procedure and method of risk-based bridge service level evaluation, it is possible to perform resonable asset management. Moreover, it is concluded that the proposed applicable method of risk-based asset management will provide a solution to contribute the development of systematical asset management for optimal decision making and prototype asset management system.

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.

This paper examines the operating performance of firms that for a four-year period, held more than 15% of their assets in cash and cash equivalents. During next four years, operating performance of firms maintaining high cash persistently is greater than the performance of firms matched by size and industry or firms adopting transitory high cash policy. Furthermore, the effect of persistent cash holdings on operating performance depends on the ownership structure and the level of information asymmetry. Foreign investors deteriorate the operating performance of high cash firms, suggesting that potential M&A and the pressure of excessive dividend reduce the usefulness of cash. The level of information asymmetry enhances the operating performance for the firms adopting persistent high cash policy. It suggests that cash holdings reduce the costly external financing and underinvestment problem for firms with high information asymmetry.

It has been constantly demanding for effective way to improve software development productivity and automation. In this paper, we did research to configure the component assets to reuse design information from the design phase domains based on the DMI. It is necessary abstracted information architecture of an independent platform development environment to reuse design information on the design stage. Also, It should be based on a well-designed to support the design architecture of the application domain. Therefore, in this paper, I want to use the DMI architecture that can be represented by formal level of architectural design information platform and application domain area. It is able to decomposition architecture asset with the part design information from the design phase composition or a high level of abstraction on DMI. Therefore, the metadata structure of the asset architecture will support a structure which can reuse the structure-based design of the domain areas.

영국, 일본은 전후복구를 위해서, 미국, 호주 뉴질랜드는 경제부흥에 힘입어 1960년대부터 사회기반 인프라의 건설을 계속 확대해 왔다. 1990년대 들어와서는 인프라의 노후화가 가중되면서 인프라의 기능을 보존하기 위한 비용이 급격히 상승하고 있다. 이들 나라는 최소의 유지관리 비용으로 사회기반인프라의 보존이나 교체시기 연장을 위한 방안으로, 1990년대 중반부터 자산관리 체계를 개발하고 있다. 한국도 경제 부흥을 위해 1980년대부터 사회기반 인프라를 집중적으로 건설하였다. 그 결과, 2010년대 후반부터 유지관리 수요가 급속히 증가할 것으로 예상되고 있다. 하지만 자산관리 선진국에 비해 우리나라는 초보적인 수준에 머물러 있다. 그래서 본 연구는 미국, 영국 뉴질랜드에서 제시한 자산관리시스템의 모듈기능과 구성을 비교분석하여 한국 실정에 적합한 사회기반인프라의 사전 예방적 유지관리를 위한 자산관리시스템 프레임워크를 제시하였다.

악성코드에 감염된 여러 대의 좀비 PC가 특정 사이트를 공격하는 해킹 방식인 DDoS 공격은 최근 7.7 DDoS 대란을 비롯하여, 1년도 채 되지 않아 3.3 DDoS 대란으로 이어지고 있다. DDoS 대란의 발생을 통해 사이버 보안 위협의 위험성이 점차 증가하고 있음을 확인할 수 있으며, 공격 경로를 통해 사용자 PC로 유입된 악성코드는 사용자의 자산인 PC에 저장되어 있는 정보들을 모두 삭제할 수 있어 공격으로 인해 발생하는 금전적, 정신적 피해가 점차 심각해지고 있다. 이러한 환경에서 조직 및 사용자가 보존해야 할 정보 자산의 기밀성, 무결성, 가용성을 실현하기 위하여 정보보호관리체계를 기반으로 지속적인 점검을 수행하여 조직 내의 위기관리 프로세스가 구축되어야 한다. 따라서 본 논문에서는 기업이 보유하고 있는 정보 자산이 외부로 유출되는 것을 방지하고, 악의적인 악성코드가 내부로 유입 되어 조직 내부의 자산을 파괴하는 위협으로부터 보안을 제공하기 위한 정보보호관리체계에 대해서 분석하고, 기업 정보보안 기능을 강화할 수 있는 방안에 대하여 제안하고자 한다.

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.

In this paper we classify the possible threat and introduce the method that measures the loss resulted from the threat in the university. This is the method that the amount of the loss minimized in the case of the same quality in damage as establish a economical prediction model. The method of measuring the loss is as follows. First, asset should be clearly identified and valued. Second, threats which may result in harm to asset should be classified. Third, vulnerabilities which is weaknesses associated with asset should be analyzed. Fourth, measure the value of the loss. we explain the valued method by the example.

The future industry, intangible assets, like expertise, customer satisfaction, and employee's volition and capability, create more company value than any other components. The company's outcome mostly depends on managing these intangible knowledge assets. Construction industry is trying to adapt knowledge management system to manage their knowledge assets, but Hey do not build up knowledge assets definition and knowledge assets classification as much as other industries do. Most researches related knowledge assets classification are not concentrated on construction industry so it is need to define knowledge assets and establish knowledge assets classification of construction based on construction characteristics and informations. With this research result, construction knowledge assets classification can be the basis of knowledge asscts evaluation and knowledge map for knowledge management system.

In the object inheritance of SR DEVS, partial or overall asset inheritance can be possible. To a asset inherited from parent object, by respective dedicated function a child object can implement partial or whole asset, or not. Even though a child has a inherited asset, if the asset is the hidden property its implementation will not be provided. A inherited asset cannot be showed in whole asset implementation, or it can be implemented by special system state. Here, the whole asset implementation means may include time parameter. In this paper, we describe a determination probability scheme for partial or whole asset inherited from the parent object to determine the hidden inheritance. By the determination probability function it is decided that the inherited asset will be hidden or normal asset.
