As a rapid development of electronic commerce transactions in these days, the security and private protection problems became more important matters under the electronic transaction base. Because electronic transaction using electronic documents be carried without direct person to person meeting, there can be the possibility to use other's identity illegally without notice, and very hard to verify authenticity of transaction as well. In addition, it is very hard to find out that the electronic documents on the process of submitting is forged documents or not, and also have much difficulty in maintaining transmitting secret. Therefore, to solve such problems on electronic commerce transactions and electronic documents, the digital signature and certification system with cryptography skill is inevitably necessary. As the wide use of digital signature together with beginning of digital government and financial transaction, not only the issuance of electronic certification, but certification market came to gradually expand. In Korea, after enacting digital signature act in 1999, the act contents were expanded to the wide range of contents complying with global standards from the end of 2001 to April, 2002, including the new clause of certification problems. And the act was put into operation now. Therefore, in this paper, we'd like to suggest development scheme through the investigation on electronic certification related problems, such as, concepts, procedures, service conditions here and abroad.

The number of business closure is one of key indicators diagnosing the status of local economy. The increases in closure are attributed to various endogenous/exogenous factors such as decreases in sales of stores, decline of local market, deterioration of global financial condition, but it is not trivial task to figure out the cause and effect mechanism among variables. The effects of those factors are expected to show geographical variations, which the empirical analysis results in this study presented. As such, the objective of this study is to estimate the effects of variables on increase in the number of business closure and examine the distributional properties of the geographic variations of the effects among spatial units of analysis. To this end, GWR (Geographically Weighted Regression) model was utilized to draw empirical analysis outcomes. It is expected that the outcomes of the sort in this research may be useful in aiding decision-making process of drafting locality-specific policies and/or deciding where to prioritize the limited public resources available.

Electronic commerce, the act of trading online, with its myriad of potential has been seldom looked at within the context of developing countries. E-commerce presents SMEs in developing economies the opportunity to adequately compete on a global stage. The exponential growth of e-commerce in developed economies further widens the financial gap between developed and developing economies. This study looks at a practical e-commerce adoption framework for Ghanaian SMEs and by extension, developing economies and looks at the net benefits that are available to current adopters. The study uses structural equation modeling, using Partial least squares (PLS) regression to analyze the data in the research. Using PLS algorithms as well as bootstrapping calculations. It combines the use of surveys (154) and interviews (38) as means of data collection. The findings of the research indicate that there is a need for legislation on e-commerce trading to regulate the trade in Ghana, with policies such as e-contracting and e-signature laws among others. Also, a current call for an expansion of the mobile payment methods within the country. For the private investor, a ripe market for logistics services. The study also proposes a simple guideline for SMEs looking to adopt or expand their e-commerce usage, that considers technological, organizational and environmental factors that come to play within e-commerce adoption.

The intensification of the processes of the digital economy development is leading to the transformation of the higher education system. Universities are forced to digitalize their own educational, research, international, marketing, financial and economic activities in order to maintain a competitive position in the global market of educational services. The purpose of the article is to study the role of information and communication technologies in the development of the higher education system and to ensure its adaptability to modern challenges of digital economy. To achieve this goal, methods of content analysis, logical generalization, systematization and a structural-functional method are used. In the article, the authors substantiate the urgency of forming a holistic strategy to ensure the adaptability of higher education to the challenges of digital economy. In the structure of this strategy, the information-technological block is singled out and described. The authors specified a set of positive synergetic effects from the introduction of modern information and communication technologies in the activities of universities. The main information threats to the digitalization of higher education related to the protection of personal data and university systems from cyberattacks and fraudulent schemes are identified. In conclusion, the authors detail the measures for the strategy implementation to ensure the adaptability of higher education to digital economy.

In today's knowledge-based economy, measurement and disclosure (M&D) of intellectual capital (IC) are crucial for enhancing business performance and competitiveness. In the global world, M&D of IC are useful means to keep investors well-informed and reduce information asymmetry. At present, very few leading corporations in India have disclosed IC information on a 'voluntary' basis. Traditional accounting practices, therefore, will need to assimilate innovations that seek to meaningfully represent the 'true-value' of the intangible assets of the company. This is an exploratory study of IC M&D by 8 Indian companies over 5-year period, using 'content' analysis and market-value-added (MVA) as research methodologies. The annual reports of companies were collected from their respective websites. As part of present study, various statistical techniques have been used to analyze the data. The findings show that the sample companies, on an average, reported a positive value of IC, along with wide-disparity, low-level of ICD. Unfortunately, the omission of IC information may adversely influence the quality of decisions made by shareholders, or lead to material misstatements. Finally, we recommend to "the international accounting bodies, to take the lead by establishing a harmonized ICD standard, and provide guidance to the big listed-companies for proper measurement and disclosure of IC, both for internal and external users."

국제적인 금융위기가 연달아 발생하면서, 금융리스크관리의 중요성이 어느 때보다 더 커지고 있다. 금융리스크관리의 주요 현안 가운데 하나는 리스크를 어떻게 측정할 것인가이며, 가장 널리 사용되고 있는 방법이 Value at Risk(VaR)이다. 금융자료가 최근 시장에서처럼 두꺼운 꼬리를 갖는 분포를 보일 때, 우리는 극단치 이론을 이용하여 VaR를 측정하는 방법을 고려할 수 있다. 이 논문에서는 꼬리가 매우 두꺼운 분포를 갖는 자료를 적합시킬 때 많이 사용되는 Peaks over Threshold(POT)를 이용하여 VaR를 측정하는 방법을 연구하였다. POT를 이용하기 위해서는 우선 일반화 파레토 분포(GPD)의 모수를 추정해야 하는데, 여기서 우리는 KOSPI 5분 자료를 이용하여 추정된 VaR의 성능을 살펴봄으로써 세 가지 다른 모수추정 방법을 비교하였다. 또한, Normal Inverse Gaussian(NIG) 분포에서 자료를 생성하여 두 가지 다른 모수추정 방법을 비교하기도 하였다. 이러한 비교를 통하여 KOSPI 수익률 자료의 첨도가 매우 큰 경우에는 최근 제안된 모수추정 방법들이 최대가능도 추정법에 비해 월등히 나은 성능을 보임을 알 수 있었고, 모의실험 자료에서도 같은 결과를 확인하였다.

본 연구 논문의 주제는 국제금융위기와 관련한 전이효과를 고려하여 설정된 표본기간 (즉, 국제금융위기 이후 6년간) 동안, 국내 자본시장에서의 재벌소속 계열사들의 연구개발비 비중에 대한 재무적 결정요인들 분석에 관한 분석이다. 이와 관련하여, 연구의 실증분석 시행을 위하여 국내 유가증권시장에 상장된 재벌그룹 소속 계열사들을 표본자료로 선정하였으며, 상대적으로 다양한 계량경제 모형들을 활용하여 연구결과의 신뢰도 제고를 추진하였다. 첫 번째 가설 검정 결과와 관련, 국내 재벌기업들로 구성된 표본기업들의 연구개발비 비중에 산업간 효과가 통계적으로 유의하게 검정되었으며, 이와 관련된 심화 연구에서 동 유의성은 국내 산업들 중, 소수의 고성장 산업들에게만 존재함이 판명되었다. 두 번째 가설 검정에서는 표본산업들을 고기술 군(그룹)과 저기술 군(그룹)으로 양분화하여, 전자의 경우 모형에 사용된 전체 설명변수들 중 전년도의 연구개발비 비중, 기업규모 그리고 현금유동성의 변화 등의 설명변수들이 재벌기업들과 비재벌기업들 간의 재무적 측면에서 차이점을 나타내는 결정요인으로서 판명되었다. 반면에 저기술 군에 대한 분석 결과, 상기 2가지 변수 (즉, 전년도 기준 연구개발비 비중과 기업규모) 이외에도 총자산 대비 유형자산의 비율이 양 비교 기업군들 간에 재무적 차별성을 나타내는 유의 변수들로서 판명되었다.
