Disaster and safety budget can be characterized as a large-scale public asset on which the government has a significant role. It is of a crucial importance to properly allocate the limited national budget to various areas as necessary. Higher investment efficiency of the budget related to disaster and safety management requires distribution criteria based on relevance and efficiency. Currently, the budget related to disaster and safety management is orchestrated through the prior consultation system. However, there is still no clear framework for reviewing the investment direction and setting the priority investment areas by prior consultation. This study analyzes the status and characteristics of disaster and safety management projects by damage type and proposes a structured system for prioritization. This framework can be useful in selecting the areas that need priority investments by damage type of disaster and safety management projects, thereby contributing to improving investment efficiency.

비트코인의 국내 활용 증가와 함께 비트코인을 둘러싼 다양한 문제들이 발생하고 있다. 이에 따라 제도적 차원에서 비트코인을 어떻게 다루어야 하는지가 지속적으로 논의되고 있으며 비트코인의 자산 성격을 분류하는 것은 이러한 논의에 중요한 기준점이 될 것이다. 본 연구는 비트코인의 자산성격에 관한 선행연구들을 기초로 하여 기능적 측면에서 비트코인의 자산성격을 분류하였다. 회귀분석을 통해 금과 미소비자물가지수(CPI), 미달러화가치(DXY), 주가지수(S&P500) 등과의 상관관계를 분석하고, 비트코인과 동일지표들 간의 상관관계를 분석하여, 금과 비트코인이 지표들과의 관계에서 유사하게 반응하는지 검증하였다. 분석 결과 비트코인은 금과 유사한 방향성으로 보이며 인플레이션과 통화가치에 대해 위험회피기능과 수익률측면에서 투자가치를 지닌 투자자산기능을 확인할 수 있었다. 이러한 기능성과 더불어 투자자산기능의 주된 요인인 가격변동성을 고려하면, 비트코인은 화폐로 분류하기 보다는 고위험 금융투자자산으로 분류하여 제도권에 편입하는 것이 관리적 측면에서 효율적일 것이다.

Illegal software use have been abroad through online (internet) and offline (CD, DVD, USB, etc.). It infringes intellectual property rights and weakens the will to software development. Also, it generates the software errors and virus intrusion in PC. It hinders national software industry and induces the personal and national trade friction. Many group (company, office, organization, institution, etc.) have been realized the prohibition of illegal software use. But, it is too hard to monitor and control illegal software use. In this paper, we propose a method of software management in a group. A software module of client agency is installed in all PC of the group. A main server of the software management controls the all of the PC through the communication. The server blocks the install of illegal software, permits the install / use of honest goods software, monitors the license (term, amount) in all the PC. The system prevents errors of illegal software use, all cuts the virus intrude through the illegal software, improves the performance of PC relatively.

The information system control includes organizational structure, control mechanism, and management tools which contribute to accomplish the goals of information system: asset safeguarding, data integrity, effectiveness, and efficiency. Information system audit is the process to evaluate whether the information system accomplishs the goals. Information system auditor examine the reliability of information system control and suggest recommendations to improve the information system control. Both information system control and information system audit activities contribute to prevent and detect the computer crime for the organization. This paper proposes a causal model of information system control/audit and the perceived risk of computer crime, and tests the model using a survey on 38 financial institutions in Korea. Statistical results show that information system control and audit significantly reduce the computer crime risk perceived by the user group. The general control has a stronger impact than the application control. In addition, it turns out that the greater the deviation between the importance and the actual level of information system control is, the higher the perceived risk of computer crime is.

유지보수단계는 설계단계에서 계획되고 시공단계에서 확보된 자산적 가치를 지속하는 건물수명주기상의 한 단계이다. 건물의 대형화 및 기능의 복합화 추세가 확대되면서 유지보수단계의 중요성은 성능관리, 안전관리, 자산관리 등의 다양한 관점에서 더욱 증대되고 있다. 최근 들어 체계적인 시설물의 정보관리 및 정보기술의 적용을 통해 이러한 관리목적의 달성과 유지보수에 관련한 제반 운영활동 및 비용의 효율성을 확보하려는 노력이 전개되고 있다. 건물의 유지보수에 있어서 핵심이 되는 기본정보는 준공된 시설물을 구성하는 세부요소에 대한 정보로, 설계 및 시공단계에서 생성된 정보를 적절히 변환함으로써 구축될 수 있다. 그러나 현재 유지보수단계에서 활용되는 정보시스템에서는 건물 및 시설에 대한 정보가 선행단계와는 단절되어 새로이 생성, 구축되고 있다. 또한 자산관리 관점에서 볼 때 시설물자산을 구성하는 구조체, 설비 등의 자산내역은 그 가치의 변동이 상이하므로, 이를 합리적으로 반영하기 위해서는 시공단계의 비용 또는 가격을 정확하게 배부, 반영하여 자산내역의 최초 가액을 산정할 필요가 있다. 본 연구는 자산관리의 측면 및 수명주기에 따른 정보의 연계성 확보측면에서 시공단계에서 발생하는 시설물의 세부요소 및 비용정보를 유지보수단계에서 활용할 수 있는 정보모델을 개발, 제시하고자 한다.

This research is interested in organization members' knowledge contribution, along with the requirement for the effective knowledge management as a critical corporate asset. We consider the performance appraisal and reward system on knowledge sharing as a key issue for the successful knowledge management. Analyzed will be the interactive relationship among the performance appraisal and reward system, individual knowledge contribution, and organizational knowledge contribution effectiveness. This case study is based on in-depth interviews in the consulting industry recognized as a knowledge-integrated industry. The purpose of this research is to examine how firms evaluate and reward organization members' knowledge contribution, to define how fim1s utilize IT for the knowledge management, and to show how the performance appraisal and reward system influence organizational knowledge contribution effectiveness. Besides, other determinants for knowledge contribution effectiveness are defined. It is recognized that knowledge contribution effectiveness is positively related to non-monetary rewards and informal appraisals. As for the future study, we recommend the empirical research based on several propositions developed in this study.

The BIM-based architectural design can be the optimal method to improve all sectors of construction industry and reduce environmental impact through digital technologies. The goals and effects of BIM needs in LH to be newly planned based on the experience of public sectors, which will ultimately contribute to maximization of effectiveness. Referring the excellent case in the UK, the current BIM standards according to maturity level 2 handle the contents related to modeling, collaborative data production, data management and assure BIM data have to be used from building construction to operation and maintenance of buildings. Therefore the strategy for the utilization of BIM for construction projects in LH consisted of three steps; first, the minimization of defects via BIM: second, strengthening the competitiveness of construction and asset management: third, upgrading the system of building production and maintenance control. After this trial, LH can accumulate know-how for building construction to be more costeffective and competitive.

본 연구는 DC제도에서 근로자가 회사로부터 지급받는 퇴직금 추계액을 사용하여 마련해야할 퇴직금 규모를 설정하였다. 또한 적립금 성장모형을 활용하여 자산의 수익률과 배분에 따른 시뮬레이션 결과로 추계액과 적립금 비교를 통하여 shortfall risk 발생수준을 확률적으로 연구하여 가장 적절한 자산배분포트폴리오를 알아보았다. 이를 위해 2004년부터 2013년까지 KOSPI와 종합채권수익률을 기초로 시뮬레이션 분석을 하였으며 적립금이 추계액보다 부족한 경우와 동일한 경우 2개의 시나리오를 설정하였다. 이를 통해 1기간 동안 주식과 채권의 자산배분에 따라 연금리스크가 발생하지 않을 확률을 확인하였고 연금리스크가 발생하지 않도록 DC가입자, 정부, 기업들이 노력할 것을 제안한다.

The role of maintenance in railway is going to be extended to improve the reliability of railway system in the aspect of Asset management gradually. In this paper, the meaning of reliability and safety in RCM which has been applied in order to improve the efficiency of maintenance is deduced. And the analysis task of reliability and safely which has been recommended in railway standards such as EN50126 and IEC62278 is reviewed in the aspect of RCM. Finally, the several ways are proposed to apply RCM to railway system through the comparison between the RCM procedure and the analysis procedure for the reliability and safety in railway standards. Hereafter, if the analysis of reliability and safety is performed with the concept of RCM in the beginning of railway business, it will be more efficient to improve the reliability and manage the railway asset.
