Internet-based on-line firms have focused on the development of new business models with an assumption that this new model would create their competitiveness. At the same time, off-line firms have opened new marketing channels on the internet in order to defend their position against on-line firms. Based on Porter's well-known generic strategy, this study compares between on-line firms and on-offline firms i) whether these two types of firms take different strategies among cost reduction, marketing differentiation, innovation differentiation, and focus and ii) how the performance of these two types of firms is affected by different strategy types. The result shows that on-offline firms prefer the strategy of marketing differentiation and innovative differentiation while the strategy of cost reduction and focus are taken without significant difference between online firms and on-offline firms. Also it is found that even though the strategy of marketing differentiation and innovation differentiation are more preferred by on-offline firms than on-line firms, these two strategy types have a significant influence on the on-line firms' performance while the focus strategy has a significant influence on the on-offline firms' performance. Other managerial implications are discussed.

This purpose of study is to identify types of study groups in online learning and the relationships between the types and teams' performance. In order to address these research questions, four study group types are developed based on Neiderman & Beise(1999)'s typology: 1) fully-supported; 2) highly-virtual; 3) traditional; and 4) inactive. And then three study group types are identified based on taxonomy-approach using cluster analysis from 46 teams participated in this study: 1) fully-supported; 2) traditional; 3), and 4) highly-virtual. The result shows that the groups are validated in the latter, except for the inactive type. The result indicates that fully-supported type groups achieved the highest performance, while the highly-virtual type group achieved the lowest performance.

Business data means data of all the documents and electronically generated on / off-line form, storage, use, and transfer the company work process. Business, organization, sales, marketing, means any data related to shipping. Many companies are investing in privacy. But not so for business data. In most companies, secret, confidential rating already exists, the basis is insufficient to establish that decisions can be analyzed in detail to reflect the actual business data in use. In this paper we want to present the criteria that can offer ways to design your business data decision matrix to establish the qualitative and quantitative criteria (evaluation indicators) that can be classified business data and protected by each class.

Although e-Finance has become more and more prevalent in everyday life, with the development of information technology, further development of e-Finance and commercial transactions has been limited. Therefore it is important for financial institutions to be aware of the significance of e-Finance risk and take appropriate actions. And an effective risk management function relies on a well-defined organization structure to eliminate gaps and minimize overlaps in risk management duties, responsibilities, and authorities. It defines and assigns risk management responsibilities, authorities, and accountabilities to appropriate personnel. The adequate organization of the risk management function is very important in the success of risk management.

This paper presents a design method of the neural network-based controller using an indirect adaptive control method to deal with an intelligent control for chaotic nonlinear systems. The proposed control method includes the identification and control Process for chaotic nonlinear systems. The identification process for chaotic nonlinear systems is an off-line process which utilizes the serial-parallel structure of multilayer neural networks and simple state space neural networks. The control process is an on-line process which uses the trained neural networks as the system model. An error back-propagation method was used for training of identification and control for chaotic nonlinear systems. The performance of the proposed neural network controller was evaluated by application to the Duffing equation and the Lorenz equation, and the proposed controller was compared with other neural network-based controllers by computer simulations.

Customized cosmetics are emerging as a consumer product that companies should pay attention to in the beauty industry due to the combination of market trends and institutional introduction of customized cosmetics. In this study, six offline service brands and online service brands currently in Korea were selected to understand the current status of domestic customized cosmetics online and offline services and to derive detailed characteristics, and the cases of each brand were analyzed. The results are as follows. First, customized cosmetics services could be classified online and offline. Second, customized cosmetics brands could be divided into general brand types and brand extension types. Third, skin data measurements could be classified into genetic analysis, big data-based surveys, and device measurements. Fourth, customized cosmetics manufacturing could be classified into a device manufacturing system, a consultant manufacturing system, and an individual production process system. Fifth, customized cosmetics distribution and delivery could be classified into same-day sales, general delivery, and regular delivery. The results of this study are meaningful in that they have identified and analyzed the current status of personalized cosmetics on-line and offline systems in recent trends, and it was confirmed that creative attempts in the domestic customized cosmetics market continue to change. It is hoped that this study will provide information and ideas to the beauty industry and related experts in the future and be used as basic data for customized cosmetics marketing

In these days, space design is evolving to the mixed reality space where fused on-line and off-line. But, standard and measure of mixed reality space has not been suggested and there has been little research about media environment and expression method as a mixed system either. That's why here I suggest four media environments and their characteristics that act not only as a critical point in the mixed reality space based on ubiquitous technology but also as a standard for spatial discerning. 1) Real space that is a media environment only seen by human visual and tactical sense is evolving using expression methods like new materials based on digital technology and LED. 2) Augmented reality space is a media environment using information instruments is expressed with diverse 2D and 3D contents. 3) Cyber Space is a environment depends totally on media instruments is produced by perfect graphic information without any spatial and physical limitations. 4) Augmented cyber space is realized only through the displays in cyber studio and is a space where real objects and graphic information are mixed. Depending on the purpose of the experience, media environment and expressional characteristics of mixed reality space can be fused, blended, and mixed, and that can be realized to the intelligent information space where one can experience without spatial, visual, informational limitations. In the future, studies on physical characteristics of contents according to the media environment characteristics are necessary.

Increasing communication through social media forming impression becomes more important. In this research, how three stimulus can build the impression of Twitter Account Owner(TAO) such as the types of the profile pictures, the types of timeline messages and the number of followers. We analysed the feelings of respondents when they face TAO's formal picture and informal picture, informative message and normal message, the number of followers. We, in addition, measured the willingness of respondents whether they want to develop their relationship online and offline as well. As a result, informative message draws positive reliability and makes respondent want to build deeper relationship with TAO at online. Respondent answered TAO's informal picture was more likable than formal picture and more reliable when informative message and formal picture were provided together. Our study shows that there are actual differences at attitudes of respondents by the types of the profile pictures and the types of timeline messages. Thus, we can conclude that TAOs can modify their impressions at online as they hope to.
