At the center of the repeating evolution of IT industry, there is mobile computing in the ubiquitous environment, and the increasing usage of smart phones contribute more to its growth. P corporation co-developed with Google and implemented smart work system called SWP for the purpose of 'communication and collaboration with co-workers' beyond the general goal of increasing productivity and comfort of employees. The primary objective of this study is to objectively analyze the influence of the effect factor from end user's perspective and user satisfaction on SWP usage, intention for continuous usage and individual performance. To accomplish this research purpose, this study established research models and hypothesis by collective review about information system success models, and tested the research hypotheses using the structural equation modeling technique by data collected from 320 SWP system users of P corporation. Variations for system satisfaction evaluation standard are 1)SW system usage 2) intention for continuous usage 3) individual performance, effect variations are 1) social factors 2) technical factors 3) combination of social and technical factors. Therefore, this study is about influence factors on success of SWP system and how the factors impact the outcome. The test results of this research model is summarized as follows. Firstly, system user's satisfaction had positive impact on all three; SWP system usage, intention for continuous usage and individual performance. Secondly, social factor 'SWP control system' and technical factor 'information quality' and 'system quality' had positive impact on SWP system user satisfaction, while social factor 'shared value' and technical factor 'service quality' did not have significant effect on user satisfaction. Shared value however, had interactive effect with 'information quality' and 'service quality'. This study is expected to contribute to spread of academic research on smart work system by suggesting a model that can show important factors for corporation while explaining the successful implementation of SWP and its continuous usage.

The purpose of this study was to compare clothing attitudes and the criteria for clothing selection between Korean and Korean-Chinese college female students in the Yanbian region of China. The subjects were selected as follows: 404 Korean female college students in the Choongchung area and 242 Korean-Chinese female college students in the Yanbian region of China. Questionnaires were used to collect the data and the data was analyzed by frequency, factor analysis, and t-test. The major results of this study were as follows: The clothing attitudes of the total respondents were classified into 5 factors: the fashion involving factor, the modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor. The modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor were significantly different between Korean and Korean-Chinese college female students. Korean consumers thought highly of the economy conscious factor and the practical user factor compared with Korean-Chinese college female students. However, Korean-Chinese college female students thought highly of the brand-name oriented factor and the modesty factor compared with Korean consumers.

User authentication refers to user identification based on something a user knows, something a user has, something a user is or something the user does; it can also take place based on a combination of two or more of such factors. With the increasingly diverse risks in online environments, user authentication methods are also becoming more diversified. This research analyzes user authentication methods being used in various online environments, such as web portals, electronic transactions, financial services and e-government, to identify the characteristics and issues of such authentication methods in order to present a user authentication level system model suitable for different online services. The results of our method are confirmed through a risk assessment and we verify its safety using the testing method presented in OWASP and NIST SP800-63.

The applications of intangible cultural heritage in China have encountered development bottlenecks due to poor user experience. In this paper, we begin to study the reasons why the user experience is not good, and to study design methods that enhance the user experience through the theory of five-factor model. Through literature study and comparative study of contestants, this paper investigates the advantages and disadvantages of their interaction design and summarizes the common problems. Next, a survey of these user populations will be conducted to find some design elements that affect the user experience. Finally, through empirical research, the design elements are incorporated into the theory of user experience modeling and case studies demonstrate that the application of the design elements is beneficial to improving the user experience.

Password-based authentication using smart card provides two factor authentications, namely a successful login requires the client to have a valid smart card and a correct password. While it provides stronger security guarantees than only password authentication, it could also fail if both authentication factors are compromised ((1) the user's smart card was stolen and (2) the user's password was exposed). In this case, there is no way to prevent the adversary from impersonating the user. Now, the new technology of biometrics is becoming a popular method for designing a more secure authentication scheme. In terms of physiological and behavior human characteristics, biometric information is used as a form of authentication factor. Biometric information, such as fingerprints, faces, voice, irises, hand geometry, and palmprints can be used to verify their identities. In this article, we review the biometric-based authentication scheme by Cheng et al. and provide a security analysis on the scheme. Our analysis shows that Cheng et al.'s scheme does not guarantee any kind of authentication, either server-to-user authentication or user-to-server authentication. The contribution of the current work is to demonstrate these by mounting two attacks, a server impersonation attack and a user impersonation attack, on Cheng et al.'s scheme. In addition, we propose the enhanced authentication scheme that eliminates the security vulnerabilities of Cheng et al.'s scheme.
