It is difficult to identify attack requests from normal ones when those attacks are based on CSRF which enables an attacker transmit fabricated requests of a trusted user to the website. For the protection against the CSRF, there have been a lot of research efforts including secret token, custom header, proxy, policy model, CAPTCHA, and user reauthentication. There remains, however, incapacitating means and CAPTCHA and user reauthentication incur user inconvenience. In this paper, we propose a method to detect CSRF attacks by analyzing the structure of websites and the usage patterns. Potential victim candidates are selected and website usage patterns according to the structure and usage logs are analyzed. CSRF attacks can be detected by identifying normal usage patterns. Also, the proposed method does not damage users' convenience not like CAPTCHA by requiring user intervention only in case of detecting abnormal requests.

Although the use of silicone hydrogel contact lenses which are known to have high oxygen transmissibility is increasing, they are being sold without any product labeling of physical properties such as water content and oxygen transmissibility. To analyze the physical properties such as the water content and oxygen transmissibility of approved silicone hydrogel contact lenses, this study collected and analyzed the approval information published on the KFDA website. Of 68 cases of domestic silicone hydrogel contact lenses analyzed in this study, 61 cases (89.7%) did not meet the international standard for oxygen permeability. This is because lenses that are not different from hydrogel contact lenses were submitted for approval as silicone hydrogel contact lenses because there is no domestic standard for silicone hydrogel contact lenses. In future, besides the information published on the website, analysis of the physical properties of a wide variety of actual silicone hydrogel contact lenses on the market is required.

This study investigated how the image exaggeration influence consumer attitude toward product in mobile shopping. Image exaggeration was manipulated by adding light effects on image and adjusting the width for slender mirror effect. Subjects were randomly allocated to four mock-mobile website stimuli. The overall results showed that the image exaggeration had negative effect on product attitude mediated by diagnositicity. First, the mediation effect of diagnositicity between exaggeration and product attitude was tested by bootstap method. The diagnositicity fully mediated between two variables and exaggeration had negative total effect on diagnositicity. The image exaggeration had no direct effect on product attitude. Second, to test the moderating effect of image congruence between the image exaggeration and diagnositicity, conditional indirect effect of diagnositicity was analyzed. As a result, the moderating effect of image congruence was significant. When consumers perceived high self-image congruence with picture image on mobile website, the exaggeration had no negative effect on product attitude. This indicates self-image congruence counteracts the negative effect of the exaggeration on diagositicity. And the moderating effect of image aesthetics between the image exaggeration and product attitude was examinated by the conditional direct effect model. The analysis found that image aesthetics had significant moderating effects particularly on high or low levels of aesthetics. When image aesthetics was perceived as high, image exaggeration had negative effect on product attitude, whereas image aesthetics was low, image exaggeration had positive effect on product attitude. This result indicated that the positive exaggeration effects existed when images were aesthetically appealing.

The study evaluates user experiences of YouTube and Vimeo, typical Video-sharing websites, to suggest guidelines that are more user-cantered and useful. I did some literature research followed with evaluation of theoretical backgrounds, present conditions and future services. Also, I used the six principles of "Creating Pleasurable Interface" by Stephen Anderson to conduct an in-depth interview. The results indicate that YouTube needs to improve availability of its functions and usability by reducing advertisement. Vimeo needs to improve its popularity by increasing popular contents and add relationship service such as personal broadcasting system and community services. I expect this study will become a good resource for upgrading user experiences of Video-sharing websites. I also believe that this study can guide other studies about user experience in other fields.

The purpose of this study was to investigate current garment sizes of women's formal jackets, targeting plus-size women in online shopping malls, and to identify effective size information involved in online apparel purchase behaviors to overcome the short comings of current garment sizes from the perspectives of consumers. Basic 88 size formal jackets from the seven companies found on the 22 websites were collected and analyzed. The data were collected from March to October 2007, and analyzed using SPSS 14.0. The results were summarized as follows. First, there was no website using standard garment size labeling with 'bust-hip-height' set up by KS K 0051 among the 22 websites. Instead, all 22 websites used garment size labeling with figures such as 88, 99, 100, 110, and 120 or with letters such as L, XL, and XXL. The websites presented no body size, but listed garment size. Furthermore, the size information was presented differently, ranging from three items of bust circumference, upper arm length, and jacket length to six items of shoulder width, bust circumference, waist circumference, sleeve width, sleeve length, and jacket length. In addition, no website presented basic information for hip circumference, despite the jacket length covering the hips. Second, a total of 85.7% the websites listed bust circumferences in 88 garment sizes collected as 100cm. Shoulder widths were presented as 39cm or 37cm. Sleeve circumferences were addressed the same, 36cm, in all websites. Third, comparing the differences between guidance sizes and measurement sizes, only 28.5% of the web sites posted guidance sizes of shoulder widths the same as those of the measurement sizes. All web sites presented guidance sizes of bust circumstances as 1 to 5cm smaller than those of the measurement sizes.

Recently, the number of academic conference information on the Internet has rapidly increased, the automatic classification of academic conference information according to research subjects enables researchers to find the related academic conference efficiently. Information provided by most conference listing services is limited to title, date, location, and website URL. However, among these features, the only feature containing topical words is title, which causes information insufficiency problem. Therefore, we propose methods that aim to resolve information insufficiency problem by utilizing web contents. Specifically, the proposed methods the extract main contents from a HTML document collected by using a website URL. Based on the similarity between the title of a conference and its main contents, the topical keywords are selected to enforce the important keywords among the main contents. The experiment results conducted by using a real-world dataset showed that the use of additional information extracted from the conference websites is successful in improving the conference classification performances. We plan to further improve the accuracy of conference classification by considering the structure of websites.

A viral marketing has been an effective marketing tool in various fields. In this study, we applied a viral marketing strategy for managing the Internet community website of scientists and engineers, KOSEN(www.kosen21.org). We developed a function that enables members to send promotional e-mails to their acquaintances, and we also designed a reward system for the members who participated in KOSEN viral marketing. With these strategies, KOSEN members reacted positively on the rewards (i.e., mileage points, gift card) and also the loyalty members took part in the viral marketing program more actively than other members. Furthermore, an attractive event was very effective for the prompt reaction of the viral marketing. Managing loyalty members is necessary for the continuous effects. The viral marketing strategies and analysis results of this research could be used for the management of an Internet service.

OASIS(Online Archiving & Searching Internet Sources) is a web archiving project of the National Library of Korea started in 2004 to systematically collect, manage, and preserve online digital information resources. In this study, the following problems were derived by analyzing the access log of the OASIS website and conducting a user survey. First, people's awareness of the OASIS project was very low, and there were many first-time visitors to the website. Second, active promotion and service reorganization to improve the use of OASIS was insufficient. The study suggested that the improvement point of this was to strengthen its own direct promotion and indirect promotion in connection with other agencies. In addition, it was proposed to enhance the service through user-customized services and to reinforce content that induces interest and fun.

This study aims to use Art brut works-the artwork of the socially underprivileged and alienated-to influence social roles in fashion design, employing a formative expression method to promote social acceptance of diversity in the industry. The research method involved investigating Art brut's concept and evolution in domestic and foreign literature and previous studies. The formative characteristics of the movement were derived by analyzing the works of Art brut artist Johann Hauser. One hundred and twenty images of Johann's work were collected through online sources like the Gugging Museum's website, Christian Berst Gallery's website were developed as fashion design using the CLO 3D program. The formative characteristics of Johann's works appeared to be transparent overlapping, divisional decorativeness emphasized simplicity, and vibrant chromaticity. Based on this analysis, the results of the 3D digital fashion designs were as follows. First, the characteristics of the atypical objects and figures in Johann's works were applied to the design silhouette, revealing a uniquely beautiful form. Second, Johann used a method in which numerous line shapes overlap and fill the area. The point of connecting the work is expressed as a graphic pattern by decorating the lines of the hem and hem of the garment with piping or attaching overlapping straps on top of pants and dresses. Third, the combination of overlapping colors used in Johann's work is a color block design of fashion, which utilizes the formative fun.
