In November 2018, virtual pop band K/DA, with the use of holograms and actual K-pop girl group members, performed its debut album titled "POP/STARS" at the opening ceremony of the League of Legends S8 final, hosted by Riot Games. The fan culture that exists for real singers adapts itself to virtual bands, and K/DA, consisting of virtual characters, encouraging the production of user created content (UCC). However, this form of UCC is different from the most common one, meaning that this type of band generates another way of consuming content. Therefore, this study examines how K/DA's digital characters are transformed and reproduced by UCC and how the original producers' content differs from them. Firstly, the development of this study considers the open characteristics of UCC, such as user type, created motivation, created process, content type and sharing method. In the second part, the virtual idol Hatsune Miku and virtual band Pentakill will be analysed to understand UCC. Thirdly, K/DA will be analyzed as a case study based on three factors: created motivation, content type and sharing method. In this manner, this study aims to explain how UCC for virtual bands reproduce and consume original content and expand their commercial value.

As the Internet is more embedded in people's lives, Internet users draw on new Internet applications to express themselves through "user-created content (UCC)." In addition, there is a noticeable shift from text-centered contents mainly posted on bulletin boards to multimedia contents such as images and videos on UCC web sites. The changes require different way of recommendations comparing to traditional products or contents recommendation on the Internet. This paper aims to design UCC recommendation methods with user behavior data and contents metadata such as tags and titles, and compare performances of the suggested methods. Real web logs data of a major Korean video UCC site was used to empirical experiments. The results of the experiments show that collaborative filtering technique based on similarity of UCC customers' preferences performs better than other content-based recommendation methods based on tag information and content metadata.

As the Internet is more embedded in people's lives, users draw on new Internet applications to express themselves through user-created contents(UCC). UCC is defined as content that is made publicly available over the Internet, reflects a certain amount of creative effort and is created outside of professional practices. This study describes the rapid growth of UCC as well as its increasing role in network-based communication. Based on the definition of UCC and the structure of emerging value chain, a taxonomy of UCC businesses is presented : UCC e-marketing business, UCC publishing business, UCC e-retailing business, and UCC development software business. This paper concludes with implications for platform and internet access providers.

This study aims to investigate the effects of UCC parody content trait on user attitude and e-word of mouth. The conventional methods had two identified factors: UCC content factors - trust, usefulness, and information, and parody content factors - humor, satire, and mockery. It also analyzes the impacts gap in UCC attitude between a high-involvement user and a low-involvement user in UCC contents. In this study, our findings are broadly summarized as follows: first, both trust and information, of UCC content factors, showed a positive impact on UCC attitude; second, both humor and satire, of parody content factors, showed a positive impact on UCC attitude; third, UCC attitude showed a positive impact on e-word of mouth, and both humor and satire were highly correlated to UCC attitude in UCC involvement user groups. In conclusion, this study is expected to give useful suggestions on selecting variables for further studies on UCC parody contents.

UCC(User Created Content) is attracted public attention in the era of web2.0 that users create, distribute and consume various kinds of media content through a web platform standing on participation, collaboration and openness. As most discussion about UCC is centered on making benefit using it, it is understood as 'the information commodity' which is appropriated to new media environment. But UCC have to be understood not only as the information commodity but as 'the state of media'. UCC can be classified into two types based on desire for transparency and opaqueness from the media's genealogical point of view which is the logic of 'remediation' that J.Bolter and R.Grusin suggested. In the convergence era that a lot of new media appear, for example IPTV and DMB, this study devise a method of the utilization of UCC from diverse aspects of remediation in the paradigm of convergence.

UCC(User Created Content) has brought about much change in the way Internet users produce, publish, and share digital content. That means that Internet users are participating in the UCC service much mure voluntarily, and interacting each other mure proactively to meet their social-psychological needs such as self-expression, social presence and so on. Also, there has been the sharp increase in variety and volume of digital content on Internet. The reasons why are that UCC enables Internet users to produce and publish their own content with much low cost, and lowers the entrance barriers to the digital content market. Like this, UCC causes the unbundling of the value chain of digital content, resulting in the high uncertainty and complexity, and then leading to the low healthiness of UCC value chain in terms of productivity, robustness, niche creation, and safety. Thus, this paper is to identify the status and problems of UCC value chain and present the way how to enhance the healthiness of UCC value chain more comprehensively and systematically.

인터넷이 UCC(User Created Content : 사용자 제작 콘텐츠)로 넘쳐나고 있다. 네티즌의 성향변화, 다양한 미디어의 출현, 그리고 이들을 만족시키는 기술의 발전이 결합되어 단순한 정보 수용자의 위치에 머물렀던 네티즌들을 이제는 정보 생산자로 변모시키고 있다. 여기에 포털 업체들이 관련 서비스를 경쟁적으로 출시, 올해 UCC서비스가 본격화될 것으로 전망된다.

일반적으로 동영상 UCC(User Created Content)는 사용자에 의해 재생산된 동영상과 사용자가 캠코더나 디지털카메라를 통해 직접 만든 동영상으로 나뉜다. 이러한 특성을 반영하듯 동영상UCC의 대표주자인 판도라TV는 재생산 된 동영상에 주력하고 있고, 후발주자이자 다크호스인엠군의 경우 누리꾼들이 직접찍은 생활과 밀접한 동영상에 주력하고 있다. 인터넷 업계의 관심이 집중되고 있는 동영상UCC의 세계로 빠져보자.
