Although small and medium-size enterprises are facing the significant trends in the Fourth Industrial Revolution and Open Innovation which are increasingly in need, the subjects of absorptive capacity and entrepreneurship has not been studied sufficiently in order to enhance the competitiveness of SMEs' products and cope with the current trend. The purpose of this study is to investigate the effects of absorptive capacity of SMEs on product competitiveness and the moderating role of CEO's entrepreneurship between the absorptive capacity and the product competitiveness. The data were collected from 313 employees of 22 SMEs in the Seoul metropolitan area, Kyunggi-do and Chung-cheong province, and analyzed using hierarchical regression analysis. As a result of the hypothesis test, both the absorptive capacity of SMEs and CEO's entrepreneurship had a positive effect on the product competitiveness. In addition, also found out the innovativeness and the proactivness out of the three entrepreneurship had the moderate roles between the potential absorptive capacity out of the absorptive capacity and the product competitiveness. On the other hand, the risk-taking out of the three entrepreneurship had the moderate roles between the realized absorptive capacity out of the two absorptive capacity and the product competitiveness. These results suggest that open innovation and technological entrepreneurship are needed to help SMEs learn external resources and information to create performance. After discussing this conclusions and implications of the study, the direction for future study was presented.

A hermetically sealed oil transformer is designed by applying expanding function of the tank due to the volume changes of the insulation oil according to the temperature rises. When the insulation oil expands, an increase in the volume of the corrugated fin prevents a pressure rise of the transformer. For a wind turbine transformer, a vegetable-oil-immersed transformer has the advantages of excellent biodegradation and fire-resistant properties like an exceptionally high fire point. When vegetable oil is substituted for mineral oil, however, the maximum winding temperature rises because of the decrease in the internal circulation flow rate resulting from the variations of the oil's physical characteristics, such as density and viscosity. The purpose of this study is to develop a hermetically sealed vegetable oil transformer that can be applied in a wind turbine and to analyze the thermal stability of the active part of the transformer to deal with pressure variations due to the temperature changes. In addition, thermal tests for the vegetable oil transformer have been performed, and the measured values are compared with the analysis results.

Web attack uses structural, logical and coding error or web application rather than vulnerability to Web server itself. According to the Open Web Application Security Project (OWASP) published about ten types of the web application vulnerability to show the causes of hacking, the risk of hacking and the severity of damage are well known. The detection ability and response is important to deal with web hacking. Filtering methods like pattern matching and code modification are used for defense but these methods can not detect new types of attacks. Also though the security unit product like IDS or web application firewall can be used, these require a lot of money and efforts to operate and maintain, and security unit product is likely to generate false positive detection. In this research profiling method that attracts the structure of web application and the attributes of input parameters such as types and length is used, and by installing structural database of web application in advance it is possible that the lack of the validation of user input value check and the verification and attack detection is solved through using profiling identifier of database against illegal request. Integral security management system has been used in most institutes. Therefore even if additional unit security product is not applied, attacks against the web application will be able to be detected by showing the model, which the security monitoring log gathering agent of the integral security management system and the function of the detection of web application attack are combined.

The counter-terrorism in Korea should be approached practically divided both internally and externally. However, in reality it is impossible for the military and the police to control all the counter-terrorism. So there is a need of precaution using the partnership with private companies. But the military and the police have stressed the conservative and closed operation. Furthermore, the focus of counter-terrorism in Korea is more on expose facto treatment than prevention, so they are almost the defenseless. In order to solve this problem, we should form the private subcontractors of the counter-terrorism experts. That is the introduction and the application of PMSCs system. First, the military and the police need to change its mind set for the partnership with private companies to prepare appropriateness. Second, it should be built up infrastructure to let the hands-up workers on counter-terrorism out place. Third, it should be set up the institutions of learning to train regularly to applicate PMSCs system and to specialize. Fourth, the training of counter-terrorism should be made it mandatory about exit passengers to danger zone. Fifth, the selection of PMSCs suitable for counter-terrorism should be strict.

Thia paper suggests a milti user-authentication system comprises that DNA biometric informatiom, owner's RFID(Radio Frequency Identification) smartcard of hardware token, and PKI digital signqture of software. This system improved items proposed in [1] as follows : this mechanism provides one RFID smartcard instead of two user-authentication smartcard(the biometric registered seal card and the DNA personal ID card), and solbers user information exposure as RFID of low proce when the card is lost. In addition, this can be perfect multi user-autentication system to enable identification even in cases such as identical twins, the DNA collected from the blood of patient who has undergone a medical procedure involving blood replacement and the DNA of the blood donor, mutation in the DNA base of cancer cells and other cells. Therefore, the proposed system is applied to terminal log-on with RFID smart card that stores accurate digital DNA biometric information instead of present biometric user-authentication system with the card is lost, which doesn't expose any personal DNA information. The security of PKI digital signature private key can be improved because secure pseudo random number generator can generate infinite one-time pseudo randon number corresponding to a user ID to keep private key of PKI digital signature securely whenever authenticated users access a system. Un addition, this user-authentication system can be used in credit card, resident card, passport, etc. acceletating the use of biometric RFID smart' card. The security of proposed system is shown by statistical anaysis.

With the removal of underwater obstacles in the Busan New Port, the water depth of the pier has been secured up to 17m, and the port authority is constantly responding to the trend of container vessels becoming larger. Also, in 2020, 24,000TEU class container ships are entering to the port, and it is planned to secure the depth in the port to 23 m later in line with this trend. Mega container ships must check in advance the factors to be considered depending on the situation at the time, and for this, it is judged that information sharing among stakeholders is necessary. In this paper, to understand the effect of the corresponding route because of the mega container ships, a transit safety evaluation was conducted based on statistical data on ship entry and departure and maneuver characteristics of corresponding ships. The result showed that the transit of the mega container ships has increased up to 8.4% comparing to the risk of 4,000TEU class container ships. Additionally, safety measures such as minimum safety depth and tug operation plans were presented by gathering opinions on operational characteristics from the perspective of pilotage for safe transit in the Busan New Port area. Through this, it is considered that it will be possible to contribute to the prevention of accidents when entering and leaving the Busan New Port.

Process mining in big data environment utilize a number of data were generated from the business process. It generates lots of knowledge and insights regarding implementation and improvement of the process through the event log of the company's enterprise resource planning (ERP) system. In recent years, various research activities engaged with the audit work of company organizations are trying actively by using the maximum strength of the mining process. However, domestic studies on applicable sales auditing system for the process mining are insufficient under big data environment. Therefore, we propose process-mining methods that can be optimally applied to online and traditional auditing system. In advance, we propose continuous monitoring information system that can early detect and prevent the risk under the big data environment by monitoring risk factors in the organizations of enterprise. The scope of the research of this paper is to design a pre-verification system for risk factor via practical examples in sales auditing. Furthermore, realizations of preventive audit, continuous monitoring for high risk, reduction of fraud, and timely action for violation of rules are enhanced by proposed sales auditing system. According to the simulation results, avoidance of financial risks, reduction of audit period, and improvement of audit quality are represented.
