In recent years, there is growing interest in 'Fin-tech' in the domestic and international financial sector. And a variety of services in such a situation has emerged. To ensure the safety of from hacking attacks, many new technologies have been developed. These leading technology is the Bio-authentication method that you consider applying to the financial sector. Bio authentication is using biometric information. Also it is known that can cope the threat of fabrication and modifying attacks with shared and stored. However, Recently, When you look at hacking incidents of biometric data(560 million cases) in the United States Office of Personnel Management and advent of the fingerprints counterfeit technology, We can be known that should be reconsidered about the safety of bio-certification. Especially, it should be provided with a response measures for the problem of embezzlement that biometric information already been leaked. Thereby In this paper, by investigating biometric technologies and practices applied and of the vulnerability factor in many industries, it expected to be utilized in the prepared threats countermeasures in accordance with the application of the biometric authentication technology in a future.

KONEX (Korea New Exchange) is the organised stock exchange for small enterprises. It is a channel through which venture start-ups at their early stage can raise funds without a huge burden of debt. We explain the regulations in this market and examine the effects of major changes in the relevant regulations. The first change was replacing the call auction mechanism with the continuous auction mechanism. The change improved the information asymmetry among investors. The second was lowering the minimum deposit requirement for individual investors from 300 million won to 100 million won. As the result of the change, market liquidity increased a lot and the number of investors increased. The last change was introducing the small investment account. Although this raised the participation of individual investors but did not lead to the improvement in market liquidity or information asymmetry. In overall, encouraging more investors to participate in the transactions in KONEX is the fast way to boost the market, while the long-term strategy should focus more on improving the information asymmetry by helping information generating and transferring activities.

As the Korean economy went into a recession because of the global financial crisis in 2008, in order to vitalize the Korean economy, the government raised SOC budget and made its execution earlier. To prevent increases in budget for the government financial investment projects, the government controlled the project cost of SOC construction projects by enacting 'Guideline for total project cost management' in 1994 and complementing the relevant system. However, different from government intention, the total project cost of SOC projects were increased drastically. Hence, the government authorities and research institutions insisted the necessity of supplementation and improvement for the total project cost management system. This research is to provide the improvement for the total project cost management system of domestic SOC projects. In this research, As-Is Model was adjusted considering status of the total project cost management in the current SOC projects. Also the cost management of construction projects between domestic and other developed countries was studied, analyzed and compared. Based on the above, problems related to total project cost management of domestic SOC projects were found out and an improved total project cost management was provided to improve these problems.

In this study, first, current state and future prospects of indirect real estate investment systems after foreign exchange crisis are analyzed, and second, policy alternatives for activating indirect real estate investment markets are examined. After foreign exchange crisis, various indirect real estate investment systems, such as REITs, ABS and CRC, were introduced. Present market size of indirect real estate investment is not larger than expected. The reasons are the problems of incomplete system on the one hand, and real estate market conditions on the other hand. But long term prospects of indirect real estate investment markets may not be pessimistic. Considering the positive effects of indirect real estate investment systems to the real estate and financial markets, policy supports for activating indirect real estate investment market may be needed.

As mobile terminal environment gets matured, the use of Android platform based mobile terminals has been growing high. Recently, the number of attacks by malicious application is also increasing as Android platform is vulnerable to private information leakage in nature. Most of these malicious applications are easily distributed to general users through open market or internet and an attacker inserts malicious code into malicious app which could be harmful tool to steal private data and banking data such as SMS, contacts list, and public key certificate to a remote server. To cope with these security threats more actively, it is necessary to develop countermeasure system that enables to detect security vulnerability existing in mobile device and take an appropriate action to protect the system against malicious attacks. In this sense, this paper aggregates diverse system events from multiple mobile devices and also implements a system to detect attacks by malicious application.
