This study examined the impact of Government-ownership of banks on the firm size using South Korean data. The impact of Government ownership of banks as both the largest lender of government banks and the bank loan dependency of firms on government-ownership bank were measured. Empirical models considering endogenous problems and various effects of firm size were developed. All results in this paper showed that government-ownership of the main banks might have a relationship with the smaller firms. In addition, the bank loan dependency of firms on government-ownership banks might have effects on the firm size. A higher loan dependency of firms on government-owned banks resulted in smaller firms. This study used micro firm level data to analyze, from several perspectives, the relationship between government-owned banks and firm size. The existing studies go as far as inferring the effects of government-owned banks showing theoretical evidence, performing surveys, or using international comparison data. This study is differentiated from existing studies in that it analyzed in a direct manner the effects of the government-owned banks on both the firm size. This study provides insights into the privatization of government-owned banks.

본 연구는 미국의 거액전자자금이체에서의 지급지시의 효력을 검토하고 그 시사점을 제시한 것이다. 거액전자자금이체에서의 지급지시의 효력은 원지시인으로부터 구속력을 가진 지급지시의 발행, 수신은행의 지급지시에 따른 승낙, 그리고 수익자에 대한 채무이행으로 발생된다. 이와 같은 지급지시는 원지시인의 지급지시취소, 수신은행의 지급지시거절, 그리고 무권한적인 지급지시인 경우에 그 효력이 소멸된다. 즉, 원지시인으로서 업증된 전송자가 발행한 지급지시를 수신은행이 승낙하는 경우에만 지급지시가 정상적으로 이행되어 전자자금이체가 완료된다고 할 수 있다. 따라서 원지시인과 수신은행은 원지시인에 대한 입증과 지급지시의 진정성을 확보하여야 한다. 이러한 입증과 진정성 문제를 해결하기 위하여 관련 당사자들은 특히 보안절차의 확립에 관하여 약정하는 것이 중요하다.

자율화와 경쟁여건의 조성을 통해 금융효율성제고(金融效率性提高)를 추구할 때 금융제도의 안전성과 예금자 보호를 위 한 제도적 장치로서 예금보험제도(預金保險制度)에 대한 고려가 병행되어야 한다. 그러나 은행의 위험에 대한 예금보험제공자와 은행사이에 정보(情報)의 비대칭성(非對稱性)이 존재하기 때문에 공정한 변동보험료제도의 실시가 불가능할 때에는 도덕적 위험문제를 피하기 어렵다는 부작용이 발생한다. 예금보험제도의 유용성을 인정하고 동제도의 목적을 충실히 수행하기 위해서는 도덕적(道德的) 위험(危險)의 억제가 중요하며 그 수단으로 은행규제(銀行規制)가 경제적 타당성을 갖게 된다. 기본적인 규제의 형태로는 적정자본금(適正資本金) 규정(規定), 업무영역(業務領域)의 제한(制限), 탄력적(彈力的)인 수신금리규제(受信金利規制)가 되어야 한다. 현재의 자율화 과정을 고려할 때 규제의 효율성면에서는 위험분담사고에 기초하는 적정자본금 규정이 주된 규제수단이 되어야 할 것으로 고려된다.

The purpose of this study is to based on review of theoretical and empirical studies to assess the independence of central banks - the former Socialist republics, including the Russian Federation and Czech, Poland. In addition, the work is expected to clarify whether a link exists between independence and the most important economic indicators such as inflation, economic activity, the budget deficit. And The subject of this study are the formal and actual independence of national banks, as well as limiting factors: political and economic. Background investigation of the problem of independence of central banks from the fact that, according to many economists, it is essential to the successful development of a market economy. The effectiveness of any country's economy due to currency volatility, low inflation, high reliability of the banking system, etc. As far as the independence of monetary regulation contributes to these goals - one of the most actively debated issues in the world of economic theory and practice for a long time. The issue of central bank independence is extremely important for Russia, Czech, Poland. In the near future to the central bank has important tasks, among which are the transition to inflation targeting in the rejection of significant intervention in the foreign exchange market, as well as improving the sustainability of the national banking system. Transparency and independence of the Bank of Russia, Czech Republic, Poland, in my view, should be an important factor in achieving these goals. The countries of Czech Republic, Poland have already made a number of steps to bring the status of their banks to the European standards. Many other developing countries are also in the process of reforming their central banks and the improving conditions of their functioning. However, despite the fact that as a model for reform used by the central banks of countries with developed market economies, central banks in developing countries are still yet deprived of the legal, economic and political independence. A different situation exists in transition space. Because of significant differences in the views of the authorities in transition republics at the necessary level of independence of central banks and the exchange rate and monetary policy reform of monetary management in these countries led to different results.

The collection and storage of a large volumes of data are becoming easier; however, the number of variables is sometimes more than the number of samples(objects). We now face the problem of dependency among variables(such as multicollinearity) due to the increased number of variables. We cannot apply various statistical methods without satisfying independency assumption. In order to overcome such a drawback we consider a categorizing (or discretizing) observations. We have a data set of nancial indices from banks in Korea that contain 78 variables from 16 banks. Genetic sequence data is also a good example of a large data and there have been numerous statistical methods to handle it. We discover lots of useful bank information after we transform bank data into categorical data that resembles genetic sequence data and apply bioinformatic techniques.

The academic credit banking system is an educational system to implement a lifelong learning society. Students who meet the requirements of this system can achieve academic degrees equivalent to those of junior colleges or four-year universities. Credits and degree information of these students are recorded and managed by the central institution. However, this system can cause security problem such as hacking due to centralized management. In this paper, we propose an academic credit banking system which can manage credits and degree information based on blockchain technology. In the proposed system, credits and degree information are stored in block and managed in the public ledger in a permanent manner. Blocks are connected in the form of blockchain on a distributed network to improve security problems such as hacking and manipulation. Also, the efficiency of credit bank management can be increased because the functions of the central institution are distributed to the network participants. The prototype of the proposed system was implemented on the Go-Ethereum platform and experimentally verified the blockchain information among participating organizations using smart contracts.
