Recently K-POP's popularity and the success story of 'Psy' suggests that Korean Culture can get the possibility of entry into the global major market. Increasing the purchasing power of global contents distribution also shows that the delivery of cultural content can be a big business model to create economic benefits. However, for sustainable diffusion of Korean culture, we need efforts to expand the business scope to the global market like the establishment of global distribution platform. In this study, we investigated key factors for activating the global content distribution and then analyzed priority of importance of the factors to be utilized the strategic alternatives using AHP method. To ensure the reliability of the study, experts (30patients) who worked more than 10 years of relevant work were included as population of the questionnaire. The results of analysis, the relative importance of content aspects were higher than technical aspects and policy aspects. In the analysis of the importance of the second layer factors, the business models of policy aspects were analyzed as a factor of top priority, then high-quality content production was selected as an important factor of the next higher ranks.

We investigated in the existential forms of heavy metals and their distribution in plant and soil surrounding ruined mine in Daduk area. The content of heavy metals in soils was more plentiful in A soil than that in another soil, excepting only Mn. The content of Mn in soils was greater in B soil than those in another soils. The content of each heavy metals, according to existential form, had different patterns on the comparision of each elements ; organic-form on Cd and As, Carbonate-form Cu, Pb and Mn and Residual-form on Fe and Zn. The popularity ration of M. senensis and J. decipiens were about 65% and 72%, respectively, and which means that these plants had resistances to heavy metals. The contents of heavy metals absorbed in root was higher than those of stem except Mn, In M. sinensis, the contents of Zn in root was similar to that of stem. To study the heavy metal contents in water, the highest content of heavy metal, mainly Fe, Mn and Zn, were calculated in extracting water.

As the Internet spreads, many people have interests in e-CRM and product recommender systems, one of e-CRM applications. Among various approaches for recommendation, collaborative filtering and content-based approaches have been investigated and applied widely. Despite their popularity, traditional recommendation approaches have some limitations. They require at least one purchase transaction per user. In addition, they don't utilize much information such as demographic and specific personal profile information. This study suggests new hybrid recommendation model using two data mining techniques, association rule and classification, as well as intelligent agent to overcome these limitations. To validate the usefulness of the model, it was applied to the real case and the prototype web site was developed. We assessed the usefulness of the suggested recommendation model through online survey. The result of the survey showed that the information of the recommendation was generally useful to the survey participants.

The purpose of this paper is to present a statistical model that can predict the rapid shift of users' attention by analyzing the lifecycle patterns of news in a social news aggregation service. Internet news service sites have a distinct characteristic in a sense that users' attention change very quickly in a short period of time. In this research, we propose a regression model for each news category which can model the decay pattern of users' attention and the content promotion policy of a social news aggregator is proven to be a major source of the rapid growth in the popularity of news. The proposed model is expected to be useful for evaluation of the social news aggregation service provider's content promotion policy that attempts to maximize users' attention as well as the diversity of news contents.

As the representative of the convergence of broadcasting and communication, the data service was expected to be a new profit source of the related industries. The data service, however, has not satisfied the expectation due to the short of killer services that make it popular with the viewers. According to the several survey reports, a lot of viewers do internet-searching using the key-words related to the TV program they are watching and, with the faith in the survey results, several trials has been performed to port established PC-based searching systems onto TV-set only to fail to get popularity among viewers. The failures are mainly caused that they did not sufficiently consider the viewers' modality that viewers seriously want not to be obstructed by anything when they are absorbed in a program. This paper proposes an MHP-based searching data service designed to minimally interrupt the viewers watching a TV program and to be synchronized with a TV program by using the searching key-words relative to it, the content of which changes as time goes on.

With the increasing popularity of the use of large-volume image database in various application, it becomes imperative to build an efficient and fast retrieval system to browse through the entire database. We present a new method for a content-based image retrieval by using a variable block size and block matching algorithm. Proposed approach is reflecting image features that exploit visual cues such as color and space allocation of image and is getting the fast retrieval time by automatical convergence of retrieval times which adapt to wanting similarity value. We have implemented this technique and tested it for a database of approximately 150 images. The test shows that a 1.9 times fast retrieval time compare to J & V algorithm at the image retrieval efficiency 0.65 and that a 1.83 times fast retrieval time compare to predefined fixed block size.

Despite the growing popularity of gay consumers as a fetching niche market, there has been little academic attention paid to the homosexual themes in print media, especially compared to research on gender, race, and sex imagery in ads. The present study aims to fill this void by examining advertisements with three different target audiences(homosexual, metrosexual, retrosexual consumer) through a comparative analysis of contemporary magazine advertisements. In this present study, we analyzed ads in three leading men's magazines (Out, GQ, and Maxim). Product (product category, price, and luxury brand) and human model (basic descriptions, sexuality, status, and masculinity) characteristics in ads were analyzed as the variables signifying the degrees of gay themes in ads across three magazines. The results showed that more expensive luxury brands were placed in GQ and Out than Maxim, and more male models were under-sexualized in Maxim than GQ and Out.
