We propose a framework for grouping photographic advertising images that employs a hierarchical indexing scheme based on efficient feature combinations. The study provides one specific application of effective tools for monitoring photographic advertising information through online and offline channels. Specifically, it develops a preprocessor for advertising image information tracking. We consider both global features that contain general information on the overall image and local features that are based on local image characteristics. The developed local features are invariant under image rotation and scale, the addition of noise, and change in illumination. Thus, they successfully achieve reliable matching between different views of a scene across affine transformations and exhibit high accuracy in the search for matched pairs of identical images. The method works with global features in advance to organize coarse clusters that consist of several image groups among the image data and then executes fine matching with local features within each cluster to construct elaborate clusters that are separated by identical image groups. In order to decrease the computational time, we apply a conventional clustering method to group images together that are similar in their global characteristics in order to overcome the drawback of excessive time for fine matching time by using local features between identical images.

Recently, companies have interests in the adoption and diffusion of customer relationship management(CRM). And, as information and communication technologies and Internet technologies proliferate, they also have interests in e-CRM, which implements CRMusing online communication channels. Until now, many researchers have tried to identify the success factors of CRM and evaluate their relative importance. However, only a few studies have dealt with the success factors of e-CRM. For this reason, we aim at identifying and evaluating the success factors of e-CRM in order to provide the companies with the guideline for preparing the implementation of e-CRM. Our study adopts analytical hierarchy process(AHP) as a tool for evaluating these factors because it has been widely applied and validated for a long time. Whereas prior studies have analyzed the success factors from the organizational and technological perspective, our study analyzes them from the functional perspective. As a result, we found that the companies should manage all the CRM components including analytic-operational-collaborative CRM in good balance. Also, we found that the sufficient support from CEO, the acquisition of good quality customer data, and theonline processing capability for responding customers' requests effectively are important for the success of e-CRM.

In this study, in an attempt to prevent depression and improve their quality of life, we investigated the relationship between the occurrence rate of depression among high school students. We used the data from the 2011-2 online census on youth health behavior conducted by the Ministry of Disease Control. There were 37,261 male students along with 36,797 female students for a total of 74,058 subjects. The rate of depression occurrence was 29.2% for male students and 39.6% for female students indicating that female students are having more depression than male students. As a result of the study, it was discovered that the male subjects felt 6.04 times more depression and the female subjects felt 6.98 times more depression as they encountered more stress. The males had 1.42 times more depression and the females had 1.60 times more depression when they had the experience of smoking. The male subjects had 1.37 times more depression and the female subjects had 1.41 times more depression when they had the experience of drinking. The males who joined in on physical activities for more than four days and those who joined in them for one to three days had 1.34 times and 1.16 times more depression respectively. The females who had physical activities for more than four days and those who had them for one to three days had 1.42 times and 1.28 times more depression respectively. As a result this study showed that there are correlations between variables relating to healthy behavior and the prevalence of depression.

This paper examines the factors that influence viewers' attitudes toward the public service broadcasting (PSB) system and the license fee. A online survey group was classified into four types on the basis of their expectations and evaluations of public values and demographic characteristics. Subsequentially, the attitudes each type of the viewers displayed toward the PSB system and the license fee were analyzed. The result reveals that young women in their 20-40s have more negative attitudes toward the PSB system than any other groups; those women tend to have high expectations on 'diversity' whereas they show low satisfactions with all the other public values. Additionally, this study attempted to detect factors that affect the attitudes toward the PSB system and the license fee. The important factors was not only the viewers' demographic characteristics but also their expectations and evaluations regrading the public values of PSB.

With the expansion of digital media platform, there has been a new conceptualization about public function of public broadcasting in and around European countries. Although there are differences between countries, Universal Access including smart and Internet media has been emphasized in Britain and France. However, there is lack of public discussion on service strategy of Internet and smart media platform when public function of public broadcasting is discussed. Therefore, this study tried to investigate not only the public function of public broadcasting in the field of Internet and smart media through audience research but also how the national public broadcasting stations ensure public interest and competitiveness in the field of Internet and smart media platform. The results suggested that smart phone users evaluated real-time broadcasting and VOD are the most important services among the public functions which public broadcasting stations have to persue. Futhermore, the users showed high intension to use when the free real-time broadcasting service is offered. Therefore, public broadcasting stations have to improve the social recognition on necessity and public interest of public broadcasting stations through the free real-time broadcasting services on Internet and smart media platform. And policies which can ensure competitiveness in the era of digital media are needed to become important broadcasting institute.

This study aims at understanding Korean fans who are also one of the most inquisitive consumers of the Korean pop products. For this purpose, it examines how Korean fandom perceives the procedures of the K-pop's globalization and constructs different perspectives of foreign fans. Firstly, it examines Korean fandom's the national pride as the K-pop expands to the global markets. Secondly, it explores how the Korean fandom rationalizes its possessive instinct while the global fans and markets becomes increasingly important. Finally, it explores how the Korean fandom constructs the different perceptions on foreign fans. In order to observe korean fans' thoughts and activities, it participates in the interactions in the tweeters and an online community. The Korean fans' perspective reflects both on individual tastes and the social dimensions in which fans live through. Through the lens of the Korean fandom, this study attempts to explicate the Korean fans' perception on foreign fans, which reflects another dimension of the K-pop's globalization.

This study aims to reveal the content of and logic behind a recent negative public sentiment toward female idols with the example of a debate over songstress IU's fourth album that was released late last year. While previous studies on fandom have focused on the identification process towards entertainers and making community, a recent phenomenon of "anti-fandom" or "malicious comments" implies that more research is needed on negative emotions such as hostility or schadenfreude (feelings of pleasure from others' misfortunes). Schadenfreude is a social sentiment that originated in modern liberalism, which features contradictions between public equality and private ownership, and that has been intensified in neoliberalism, which features a maximization of this contradiction centering on a meritocracy. Celebrities in Korea often become the targets of schadenfreude, which is associated with the suspicion that they gain popularity not from their abilities but from "just being popular." It should also be noted that this kind of schadenfreude operates differently between male and female entertainers. Specifically, the acquisition of money and fame by modern women whose presence used to be located in the private possessions of males is considered to be due to their unjustified use of sexuality. This is also the background of the recent online misogyny culture in Korea. In this context, IU, who had been successful at building a differentiated image of "sister-like idol artist," became a valid target. Although accusing IU of utilizing pedophilia reflects a stalemate that a current politics of sexual violence faces, it rather damages the name of an individual than attracts public attention to the structural causes of childsexualabuse. This is why I see the way that pedophilia was used in the debate over IU as a schadenfreude. Consequently, the term pedophilia here contributes to an expansion of the entertainment economy that is sustained by rises and falls of the celebrities' stock prices.

Since the Arab spring in 2010, SNS prompted discussions about the roles to organize collective actions. First of all, mobile media and SNS help to mobilize both on and offline social movement, second, to create new forms of collective actions, third, to organize social movement organizations across the world, fourth, to empower movement participants to develop new collective identities. On the other hand, the same technologies also hinder social movements from developing continuity and dedication. In addition, the problems of digital divide might aggravate the divisive process to organize collective actions across the world. This research is built on these ongoing arguments about the potentials and limitations of new media technologies. In particular, this research tries to move beyond the confrontational approaches to the media through the case study of Save The Jeju Island social movements on Facebook. The movement SNS on Facebook aims to provide as well as organize international SMOs and activists that might help deeper understandings on the potentials and limitations of online communication strategies for global social movements.

It has been only few years that various contents information subject for information processing system has been remarkably increased in online. If we say the year 2000 is the technology based year when deluge of information and data such as real time sharing, the time since after 2000 until 2011 has been a period plentiful of application based functions and solutions. Also, as the applicable range of these information process systems extends, individual information effluence has been social issues twice in 2009 and 2010. Thus now there are continuous efforts made to develop technologies to secure and protect information. However, the range problem has been extended from the illegal access from outside to the legal access from internal user and damages by agents hidden in internal information process system and client system. Therefore, this study discusses the necessity for the studies on efficiency based information security by control of access to internal information and authority setting for administrator and internal users. Based on the result of this study, it provides data that can be used from SOHO class network to large scale for information security method.
