The financial industry recently introduces several issues for utilizing the blockchain technology as the core infrastructure of future finance. Blockchain, first introduced as the underlying technology of Crypto-currencies, Bitcoin is a technology that can ensure the integrity and reliability of data by verifying, recording, and storing data jointly in the network without a central administration organization or a manager. This blockchain has its potential power as a technology for issuing digital currencies, providing transparency, and securing record management, that is expected to be useful in the financial sector. At the same time, considering the characteristics of financial transactions which emphasize privacy, questions are raised about whether a blockchain structure in which information is distributed and shared among participants can be successful. How will we support to implement the potential of the blockchain in order to change the paradigm of the financial industry? How can we manage the side effects of blockchain effectively? Such a policy discussion is necessary. This study introduces the meaning of the blockchain technology, various utilization attempts, and possible problems facing technology from the viewpoint of financial industry, and suggests a policy direction for utilizing this technology as a catalyst to the progress of the financial industry or as a new technology power.

블록암호 Zorro는 AES와 비슷한 연산과정을 거치나 S-box 개수를 줄여 부채널 공격에 대비한 마스킹을 구현 비용을 줄일 수 있게 설계되었다. 하지만 마스터키를 라운드키로 그대로 사용하기 때문에 연관키 차분공격 관점에서 취약하다. 본 논문에서는 Zorro의 연관키 차분특성을 이용해 키 복구 공격을 보인다. 또한 안전성이 증명된 12가지의 PGV 모델을 Zorro를 기반으로 할 때 블록암호의 연관키 차분 특성이 해시함수 충돌쌍 공격에 어떻게 활용될 수 있는지 설명하고 실제 충돌쌍을 제시한다.

Purpose - This paper explores the determinants of bank lending to firms during and after the global financial crisis using firm- and bank-level data to answer the questions what caused the contraction of lending to firms despite the loosening monetary policy during this crisis period. Research design, data, and methodology - We investigate the effects of the monetary policy that followed the global financial crisis on firms borrowing. We use a dynamic panel model to address how firms lending respond to monetary policy. The data are obtained from CRETOP and we consider the manufacturing sector for the analysis to control for unobserved heterogeneity such as industry-specific shocks. Results - The findings from the empirical analysis suggest that both bank- and firm-level characteristics are significant determinants of bank lending. Especially, we find that corporate risk, measured by default risk, is one of the key factors that led to a decline in lending during the crisis. Conclusions - This paper shows that companies borrow more from liquid banks, and high bank capital can also contribute to an increase in a firm's borrowing from banks. Especially, the results confirm that the default rate measured at the firm level has increased during and after the global financial crisis, which implies that default risk interplays with other firm and bank-level characteristics.

ERP systems are comprehensive sorfware packages that seek to integrate the complete range of lbusiness processes and functions in order to present a heuristic perspectives of a firm from a single information and information technlogy architecture. The ERP systems have delicate internal controls with built-in devices. It is known that the delicate internal controls help to enhance the accounting transparency. We empirically investigate the relationship between the ERP systems inplementations and an accounting transparency. In order to measure the accounting transparency differences, we compare the ERP systems implementation firms with firms which did not implement the ERP systems by 6 financial ratios (accruals, net profit margin, operation cash folo to sales, total debt to equity, accounts receivable changes, assets quality). Data are collecte from 135 firms implemented the ERP systems and 135 firms non-implemented the systems (the firms listed in the Korea Stock Exchange). We analyze financial statements from 270 firms for the period 2001-2003 to ezamine the 6 financial ratios differences. The results of 810 firms analyses over the 3-year period indicate that the ERP systems implementation firms show the statistically significant differences in the accrual ratio, the net profit margin ratio, operating cash flow to sales ratio, and total debt to equity ratio from the ERP systems non-implementation firms. But there is statistically no differences between the two groups for accounts receivable changes to sales ratio and assets quality.

Purpose - The purpose of this paper is to examine the determinants of non-bank depository institutions (non-bank financial corporations) lending to firms. The paper aims to contribute to the existing literature by providing empirical evidence from firm-level data and unveiling factors related to access to non-bank financial corporations by firms. Research design, data, and methodology - We used the data on borrowing by firms from CRETOP from years 2008 to 2011. Using the manufacturing industry, we examined what firm-level characteristics explained the increase in borrowing from non-bank financial corporations rather than the banks. Results - Analyzing the firm-level data from 2008 to 2011, we found that firms were more likely to borrow from non-bank financial insti­tutions as the size of the firm increases, implying that large firms have more access to non-bank financing than small and medium-sized firms. In addition, it also showed that small and medium-sized firms moved to non-bank financial corporations for loans. Conclusion - Non-bank depository institutions are not a sub­stitute for bank lending to firms. More specifically, they replace bank lending to firms mostly for large firms rather than small and medium-sized firms. Also, collateral and other firm-level characteristics do not matter in accounting for non-bank lending to firms.

Purpose. For more effective hospital management, it analyzes the trend through general characteristics, balance sheet, income statement, and financial ratio analysis, grasps the causes of the problems, and analyzes management of the hospital in order to use the result as baseline data for development of the hospital in the future. Methods. The collected data of 3 years from 2011 to 2013 about 3 tertiary hospitals in metropolitan cities from Alio (provider of public institution information; www.alio.go.kr), Health Insurance Review & Assessment Service (www.hira.or.kr), and the website of the Ministry of Health and Welfare (www.mw.go.kr) were analyzed and general characteristics, balance sheet, income statement, and financial ratio, analysis are used as data. Results & Conclusions. From the result of data analysis from 2011 to 2013, general characteristics, balance sheet, income statement, financial ratio analysis, and pie charts could lead to conclusions as follows. In the result of comprehensive analysis, the 3 tertiary hospitals showed increase of fixed expense due to extension of the buildings and so did the scale of fund and asset. Although medical revenue increased, the margin of increase for medical expense was greater than that of medical revenue, which consequently led to loss. In prediction for the 3 tertiary hospitals based on characteristics so far, it is expected to see improved revenue structure after building extension is completed, but it is necessary to exert management effort to maintain its optimal level by enhancement in stability of management and inventory turnover through management of inventories.
