최근 인터넷의 사용이 일반화되면서 온라인상의 저작물을 무분별하게 다운받거나 재사용하는 사례가 증가하면서 온라인 저작물 침해에 대한 보호정책이 시급해졌다. 본 논문에서는 온라인 저작권 침해에 대한 보호책으로 강화되고 있는 법적규제 및 처벌과 저작물 침해에 대한 윤리의식 고취가 온라인 사용자의 행동과 의도에 어떠한 영향을 미치는지 실증연구를 통해 분석한다. 본 논문의 목적은 온라인 침해에 대한 합리적인 해결책을 제시하고, 온라인 침해와 올바른 사용에 대한 도덕적, 윤리적인 학습과 제도의 중요성을 부각시키고자 한다. 이 연구의 결과는 처벌과 윤리의식 모두 사용자의 저작권 침해행위에 영향을 미치며, 특히 사용자의 윤리의식이 저작물 침해행위에 더 큰 영향을 미치는 것으로 나타났다.

우리나라는 홍수피해를 평가하기 위한 방법으로 간편법과 개선법을 사용하다가 현재는 2004년도에 개발된 다차원 홍수피해액 산정기법을 활용하고 있다. 본 연구에서는 GIS 자료를 기초로 다차원 홍수피해액 산정기법을 이용한 댐 하류지역의 홍수피해액 평가기법을 제시하였다. 먼저 배수강제알고리듬에 기초한 횡단측선 레이어에 FLDWAV 모델을 이용한 홍수위 자료를 입력한 후 DEM 자료와의 공간연산 처리를 통해 침수심 격자를 생성하였다. 그리고, 수치지형도에서 추출한 건물 레이어와 토지피복도에서 추출한 농경지 자료를 이용하여 지자체별 건물과 농경지 자산가치를 평가하였다. 또한 건축형태별 건축단가, 도시유형별 가정용품 평가액, 농작물 단가정보, 사업체의 유형 및 재고자산 평가액 자료를 건물, 농경지, 침수심 레이어와 연계하여 항목별로 피해액을 산정하였다. 홍수피해액 분석을 통해, 200년 빈도의 홍수피해액이 100년, 50년, 10년 빈도에 비해 각각 1.19배, 1.30배 그리고 1.96배 높게 나타났다.

The literature about intelligence assets allocation focused on mainly single or partial assets such as TOD and GSR. Thus, it is limited in application to the actual environment of operating various assets. In addition, field units have generally vulnerabilities because of depending on qualitative analysis. Therefore, we need a methodology to ensure the validity and reliability of intelligence asset allocation. In this study, detection probability was generated using digital geospatial data in MGIS (Military Geographic Information System) and simulation logic of BCTP (Battle Commander Training Programs) in the R.O.K army. Then, the optimal allocation mathematical model applied concept of simultaneous integrated management, which was developed based on the partial set covering model. Also, the proposed GA (Genetic Algorithm) provided superior results compared to the mathematical model. Consequently, this study will support effectively decision making by the commander by offering the best alternatives for optimal allocation within a reasonable time.

Recent trend of business is characterized by a recognition of importance of knowledge asset. Especially, this phenomenon is receiving more momentum as our society goes digital rapidly. However, most of literature on knowledge management is based on knowledge circulation from the corporate point of view, not from individual viewpoint. In this regard, this paper is concerned with proposing knowledge circulation process and its efficiency from the individual perspective. We adopted structural equation model or SEM to prove the statistical validity of our research framework. Eight hypotheses were built and tested empirically, leading to the fact that the knowledge utilization and sharing of individuals have a positive impact on the knowledge management efficiency.

The purpose of this study was to examine the volatility of bitcoin, diagnose if bitcoin are a systematic risk asset, and evaluate their effectiveness by estimating market beta representing systematic risk using GARCH (Generalized Auto Regressive Conditional Heteroskedastieity) model. First, the empirical results showed that the market beta of Bitcoin using the OLS model was estimated at 0.7745. Second, using GARCH (1, 2) model, the market beta of Bitcoin was estimated to be significant, and the effects of ARCH and GARCH were found to be significant over time, resulting in conditional volatility. Third, the estimated market beta of the GARCH (1, 2), AR (1)-GARCH (1), and MA (1)-GARCH (1, 2) models were also less than 1 at 0.8819, 0.8835, and 0.8775 respectively, showing that there is no systematic risk. Finally, in terms of efficiency, GARCH model was more efficient because the standard error of a market beta was less than that of the OLS model. Among the GARCH models, the MA (1)-GARCH (1, 2) model considering non-simultaneous transactions was estimated to be the most appropriate model.

In the digital world, the transactions of assets with intrinsic value can be applied to games, literature, art, and music by issuing NFTs (Non-Fungible Tokens) based on Blockchain; various NFT exchanges are emerging accordingly just like real world asset exchanges. However, there could be an issue of copyright infringement in those NFT transactions. Therefore, this paper has classified the types of copyright infringement that may occur in NFT exchanges and proposes the copyright infringement countermeasures according to them. For this purpose, 10 types of NFT exchange are examined. Eventually, it can be expected that the proposed countermeasures will contribute to the revitalization of the NFT market by providing solutions for those issues.

Since NFTs can be used like certificates due to the nature of blockchain, their use in various digital asset trading markets is expanding. This is because NFTs are expected to be actively used as a core technology of the metaverse virtual economy as non-transferable NFTs are developed. However, concerns about NFT security threats are also growing. Therefore, the purpose of this study is to investigate and analyze NFT-related infringement cases and to clearly understand the current security status and risks. As a research method, we determined NFT security areas based on previous studies and analyzed infringement cases and threat types for each area. The analysis results were systematically mapped in the form of domain, case, and threat, and the meaning of the comprehensive results was presented. As a result of the research, we want to help researchers clearly understand the current state of NFT security and seek the right research direction.

The financial MyData service has implemented in January 2022 and launched 45 services by banks, securities, credit cards and fintech companies. This study applied the Q methodology, to identify the user types of MyData services and compared the perceptions of employees of financial institutions who plan and develop the MyData services. There are three types of MyData service users: active users, limited users who focus on consumption and asset status inquiry, and sensitive users for personal information. There were two types of recognition of financial company employees. One is the active user support other is the sensitive user for personal information support. The analysis of subjective perceptions can be used as a reference for establishing a company's MyData service marketing strategy and establishing related policies to improve the MyData ecosystem.

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.
