Because financial industry is closely related to the daily lives of people, internal fraud such as embezzlement by the employees can cause serious damage to the national economy, including credit crunch and contagious bankruptcy, as once demonstrated in the Savings Bank Scandal in 2011. Therefore, the importance of financial industry security is being emphasized and developed into converged security that combines physical, human and cyber security. In this study, to prevent fraud caused by internal employees in Korean financial sector, in-depth semi-structured interviews were conducted with a total of 16 participants including bankers, officials of financial regulators, and security experts, who were in charge of risk management in the industry. The collected data were analyzed at three stratification levels such as individual, organization, and socio-cultural factor. Based on this analysis, policy recommendations were suggested for the development of financial industry security and reducing internal fraud in banking institutions.

This study is to present a improvement directions for the protection of industrial key technology. For the purpose of the study, the survey was carried out on the administrative security activity of 68 enterprises including Large companies, small-midium companies and public corporations. survey result on the 10 items of security policy, 10 items of personal management and 7 items of the assets management are as follows; First, stable foundation for the efficient implement of security policy is needed. Carrying a security policy into practice and continuous upgrade should be fulfilled with drawing-up of the policy. Also for the vitalization of security activity, arrangement of security organization and security manager are needed with mutual assistance in the company. Periodic security inspection should be practiced for the improvement of security level and security understanding. Second, the increase of investment for security job is needed for security invigoration. Securing cooperation channel with professional security facility such as National Intelligence Service, Korea internet & security agency, Information security consulting company, security research institute is needed, also security outsourcing could be considered as the method of above investment. Especially small-midium company is very vulnerable compared with Large company and public corporation in security management, so increase of government's budget for security support system is necessary. Third, human resource management is important, because the main cause of leak of confidential information is person. Regular education rate for new employee and staff members is relatively high, but the vitalization of security oath for staff members and the third party who access to key technology is necessary. Also access right to key information should be changed whenever access right changes. Reinforcement of management of resigned person such as security oath, the elimination of access right to key information and the deletion of account. is needed. Forth, the control and management of important asset including patent and design should be tightened. Classification of importance of asset and periodic inspection are necessary with the effects evaluation of leak of asset.

The postpurchase process is the phase that consumers evaluate products or services while using them. And then, they may experience satisfaction/dissatisfaction and emotions elicited products or services. The satisfaction and emotions may be important concepts in consumer behavior such as brand attitude, purchase intentions and using. The purpose of this study was to examine the effects of emotions elicited clothing products on product satisfaction and using in postpurchase. The subjects in this study were selected 500 females. The data were collected by using questionnaires, and 431 data were analysed. The results were as follows: The emotions in postpurchase process were consisted of three dimensions; unpleasure, pleasure, security/activity. These three emotions had the causal effects on product satisfaction significantly, and the unpleasure influenced stronger than others on satisfaction. In addition, the emotions were related to using and the ownership of clothing products. The emotions of pleasure and the security/activity influenced on the ownership, and the security/activity and unpleasure influenced on using clothing products. Therefore, the results in this study imply that consumption emotions elicited clothing products would be multidimensional, and the emotional factors would be important indicators for explaining the satisfaction. The positive affects were related to using clothes, which is, the consumer would have fulfilled their hedonic desires by wearing clothes. Also, the positive affects would be the basis for marketing strategies of sales promotions in clothing products.

With the rapid development of information technology in 21st century, networks are being used with various devices. Most human actions are processed through cyber space, and it is no longer separate from daily life; it has changed into one of the most important aspects of human life. Unfortunately, in cyber space, certification method has not only technical problems, but also ethological problems. Many users seemed to use the same password throughout several sites. And for a long period they refused to change it or made a small change from the earlier password. This research aims to discuss general factors of choosing and using passwords within information security through statistical analysis.

In this paper, a new user identification method is presented using real environmental human-computer-interaction (HCI) behavior data to improve method usability. User behavior data in this paper are collected continuously without setting experimental scenes such as text length, action number, etc. To illustrate the characteristics of real environmental HCI data, probability density distribution and performance of keyboard and mouse data are analyzed through the random sampling method and Support Vector Machine(SVM) algorithm. Based on the analysis of HCI behavior data in a real environment, the Multiple Kernel Learning (MKL) method is first used for user HCI behavior identification due to the heterogeneity of keyboard and mouse data. All possible kernel methods are compared to determine the MKL algorithm's parameters to ensure the robustness of the algorithm. Data analysis results show that keyboard data have a narrower range of probability density distribution than mouse data. Keyboard data have better performance with a 1-min time window, while that of mouse data is achieved with a 10-min time window. Finally, experiments using the MKL algorithm with three global polynomial kernels and ten local Gaussian kernels achieve a user identification accuracy of 83.03% in a real environmental HCI dataset, which demonstrates that the proposed method achieves an encouraging performance.
