Infringement of information security has caused the corporate image to be damaged and share price to fall, and it is emerging as an organizational risk. The value of information assets in enterprises has led to a higher level of security than in the past. As a result, companies are aware of the need for officers to protect information and to oversee a security management system. However, despite the growing importance of information security officers, there is a lack of research on their roles and characteristics. This study validates the relationship between determinants that affect the performance of information security. And a structural equation model was presented and empirically analyzed to see the impact of the internal and external characteristics of the staff in charge of information security on the organization's information security performance.

A lot of computer users use external memory device. But, same time file efflux incidents are also increasing. There are two ways people use for efflux file. One is moving it after checking file which is running on computer and the other is checking file name only. Checking from running file case, we can identify vestige with running information of applied program but, the case of moving as external device without running file there is no evidence running applied program. So there are a lot of difficulty with forensic investigation. In this paper we suggest the way to help forensic investigation which is method of getting external memory device information of volume and time through its awareness method and connection information and moving to external device without running file after compare the external memory device volume information through link file analysis and getting information of link file formation & access time from link file.

The counter-fire operation system performs its mission exchanging information with other related systems such as command & control systems and military information systems. In the process of exchanging information, the counter-fire operation system uses a type of data message which contains exchange data information in the format of KMTF. The requirement of data exchange of count-fire operation will continue to evolve. But the EDX(External Data eXchange) configuration item of the current counter-fire operation system can not effectively cope with the variation of data exchange requirements due to its fixed software structure. In the paper, a solution for improving flexibility of external data exchange in counter-fire operation system is proposed.

There is a growing awareness about the role of the board of directors in decision making, which is crucial to vitalize board activities in Korean firms. Given the academic and social needs, the current study is designed to identify the relationship between board independence and the board involvement of directors, highlighting the important aspects of information provision from diverse channels and information sharing among external directors. In this study, I include not only traditional variables to address the structural independence of the board but also the information provision and information sharing variables to explain how external directors, on average, are involved in board decisions. The research results from 136 Korean business samples show positive relationships between board independence and board involvement, but the influence of information provision and sharing proves to be significant in increasing the level of the board involvement of external directors. These findings suggest that active communication and information sharing among external directors, as well as an independent structural design for the board of directors, are important factors to improve the level of board involvement. Based on these results, the current paper provides theoretical and practical implications for corporate governance and knowledge management. Future research directions and limitations are also discussed.

This study reviewed the influence of consumer innovativeness and consumer knowledge on external information search behavior for the purchase of high-tech products. The strategies for offering information effectively for high-tech products may be proposed as follows based on the results of this study. First, the advertisements of high-tech products which are generally encountered need to offer sufficient information about the products in addition to fulfilling the function of persuading consumers. Second, it is necessary to implement an information network so that neutral offerings of information about high-tech products may be made promptly by reliable institutions. Third, information about high-tech products should be offered with easier explanations so that there should be no information-underprivileged class in utilizing the function of high-tech products.

The objectives of this study is to analyze the impact of open information innovation which consisted of external technology acquisition and external technology exploitation on export performance by integrating with strategic alliance factors. This study empirically analyzed six hypotheses in 201 sample using the PLS (Partial Least Square) of the structural equation model to verify the moderating effects of organizational culture on the relationship among open information innovation, strategic alliance and export performance. As a result, external technology acquisition dose not affect strategic alliances. On the other hand, external technology exploitation has a positive impact on strategic alliances. Strategic alliances also have a positive impact on export performance. As a result of the moderating effect analysis, the interaction between organizational culture and external technology acquisition has positively influenced strategic alliances. In addition, the moderating effect of organizational culture and external technology exploitation has a significant effect on strategic alliances. However, moderating effect of organizational culture and strategic alliance dose not affect export performance. This study has a contribution to the analysis of the moderating effects of organizational culture. In the future, integrated analysis of open information innovation and external factors is needed.

This paper proposes LF-MMI (Lattice Free Maximum Mutual Information)-based acoustic modeling using external knowledge for speech recognition. Note that an external knowledge refers to text data other than training data used in acoustic model. LF-MMI, objective function for optimization of training DNN (Deep Neural Network), has high performances in discriminative training. In LF-MMI, a phoneme probability as prior probability is used for predicting posterior probability of the DNN-based acoustic model. We propose using external knowledges for training the prior probability model to improve acoustic model based on DNN. It is measured to relative improvement 14 % as compared with the conventional LF-MMI-based model.

This research empirically analyzes not only the direct impact of the external technological information network diversity of small and medium-sized enterprises (SMEs) on the sales growth from their technology development but also the mediating impact of their productivity improvement and the moderating effect of the technology development driven by CEO on this direct impact in order to deepen the research stream on SMEs' external technological information network. Based on the ordinary least squares regression by using 2,200 data of South Korean SMEs, this study reveals the three findings. First, SMEs' external technological information network diversity positively influences their sales growth from technology development. Second, SMEs' productivity improvement partially mediates this positive influence of the external technological information network diversity. Third, SMEs' technology development driven by CEO moderates the positive influence.

There have been many studies that open innovation activities have positive effects on firm performance. However, the previous studies have shown conflicting results, depending on the characteristics of companies or the timing of the product launch. This study empirically compares open innovation performance of first-mover companies and follower companies. The analyses are performed on the samples of the Korean Innovation Survey 2010 companies that explored external information and performed R&D cooperation. The results indicate that open innovation activities can have different effects depending on a company's status in the market. For the first-mover companies, the intensity of utilizing external information has greater impact on the firm's performance than the diversity of it. By contrast, for the follower companies, the diversity of utilizing external information has greater impact on the firm's performance than the intensity of it. In terms of R&D cooperation, the external cooperation is found not to have significant effects on a first-mover company's performance. However, external R&D cooperation of a follower company is showing positive impact on the firm's performance. The implication of the study is to analyze the firm's Open-Innovation performance by comparing first-mover companies with follower companies. Therefore, companies need to execute the Open-Innovation strategy by considering firm characteristics or the timing of the product launch.
