Collaborative filtering(CF) for the personalized recommendation is a successful and popular method in recommender systems. But the mainly researched and implemented cases focus on dealing with independent items with explicit feedback by users. For the domain of TV program recommendation in VOD service platform, we need to consider the unique characteristic and constraints of the domain. In this paper, we studied on the way to convert the viewing history of each TV program episodes to the TV program preference by considering the series structure of TV program. The former is implicit for personalized preference, but the latter tells quite explicitly about the persistent preference. Collaborative filtering is done by the unit of series while data gathering and final recommendation is done by the unit of episodes. As a result, we modified CF to make it more suitable for the domain of TV program VOD recommendation. Our experimental study shows that it is more precise in performance, yet more compact in calculation compared to the plain CF approaches. It can be combined with other existing CF techniques as an algorithm module.

This study examines demand of the Korean TV VOD using monthly aggregate data and time series analysis models. In particular, the impact of box office attendance, number of IPTV subscribers, income and price of substitutes on TV VOD market is analyzed. Data on TV VOD download during the period 2013 January to 2018 June are used for the empirical analysis. TV VOD demand shows lower level of seasonality than box office attendance and the share of monthly top1 movie in TV VOD platform is also lower than that of box office attendance. The relationship between a movie's holdback and box office performance does not seem consistent. The empirical result of ARDL model reveals that in the short-run box office attendance, number of IPTV subscribers and price of substitutes have significant impact on TV VOD demand. The result on the long-term relation shows that income is the only determinant of TV VOD demand. The impact of box office attendance on TV VOD is not shown to be robust both for the short-term and long-term.

This study discussed how the Moo-hyup prototype that has been formed from novels and comics was applied to TV drama in modern form beyond martial art movies, historical TV series and games by exploring Japanese TV drama . This study showed that follows the Moo-hyup prototype such as imaginary space and violence, the relationship between characters with the spirit of Moo-hyup, and the structure of Moo-hyup story rather than a story of teenagers' growing-up. This study is ultimately expected to reveal the possibility that the Moohyup prototype can be applied to the TV drama in modern form as well as historical stories.

Objective: This paper focuses on the new trend of applying NUI(natural user interface) such as gesture interaction into television and investigates on the design improvement needed in application. The intention is to find better design direction of NUI on television context, which will contribute to making new features and behavioral changes occurring in next-generation television more practically usable and meaningful use experience elements. Background: Traditional television is rapidly evolving into next-generation television thanks to the influence of "smartness" from mobile domain. A number of new features and behavioral changes occurred from such evolution are on their way to be characterized as the new experience elements of next-generation television. Method: A series of expert review by television UX professionals based on AHP (Analytic Hierarchy Process) was conducted to check on the "relative appropriateness" of applying gesture interaction to a number of selected television user experience scenarios. Conclusion: It is critical not to indiscriminately apply new interaction techniques like gesture into television. It may be effective in demonstrating new technology but generally results in poor user experience. It is imperative to conduct consistent validation of its practical appropriateness in real context. Application: The research will be helpful in applying gesture interaction in next-generation television to bring optimal user experience in.

With love as the theme and mythology, ghosts and magic as elements, Korean fantasy TV dramas have set romantic and beautiful plots and attracted a large number of Chinese female audiences. Based on Melodramatic Imagination and Stuart Hall's theory of "encoding/decoding", this paper investigated Chinese female audiences' motives of watching Korean fantasy TV dramas Hotel Druena through the form of focus group interviews to interpret reasons for the popularity of Korean fantasy TV dramas and Chinese women's overall cognition of Korean TV dramas from the perspective of female audiences. Thinking that South Korea's fantasy dramas are good at women's pursuit and desire for emotional elements, women who watch this type of south Korean TV dramas are temporarily relieving pressure of real life, thus satisfying the needs of female gaze and consumption.

The development of social media in the 2000s led the unspecified individuals to band together for common interests. Social networking services served as a far-reaching tool for sharing different thoughts and interpretation of the pop culture and helped people build up close relations driven by their common interests for certain works of the pop culture. This Study introduces the TV Series as a case that displays specific patterns of communication between its producer and viewers. Producer Bryan Fuller of the Series as well as key production staffs were quite active on social networking sites with the understanding of what the audience desired and the willingness to sympathize with them, which were eagerly welcomed by the dedicated audience whose number, though, was not big. For the Hannibal production team, SNS was a means for them to just be consumers who appreciate the work instead of solely being the content provider. Their approach is quite different from unilateral marketing approaches employed in the past. Through this case, the Study aims to suggest that social networking sites serve as a powerful medium connecting producers and viewers or as an information hub, and that how interactive contents shall be delivered in the new media environment to be effective.

The purpose of this study is to examine how the masculinity types of the male lead appearing in melodrama genre TV series with 2005 as the borderline when we perceived the change of female types in TV drama series. To attain the goal, the paper analyzed the change of the male lead in 74 melodrama series that ranked high from 1992 till 2012 in terms of the ratings. As a result, from 2005, the types of masculinity of the male lead changed significantly. The followings deal with the details of the change: first, about the age of the male lead, those in the 30's or older increased. Second, unmarried men increased. Third, more of them saw men and women equally, and masculinity types setting no role division for men and women increased. Fourth, masculinity types of having more concern over their appearance increased. Fifth, masculinity types of relying on others when a problem occurred increased. Sixth, in relationship with others, passive masculinity types increased. There was no change in men's jobs, economic level, personality, or sexual consciousness. This study result shows that from 2005, stereotyped masculinity types shown in advanced research have disappeared a lot, and the current men image tends to show both male and female features.

The LLC series resonant converter with a LLT (Inductor-Inductor-Transformer) transformer design process and experimentation results for PDP TV power supply is presented. LLT transformer used to combine the inductor and transformer into one unit has the increased leakage inductance in the primary and secondary due to the winding method and the use of the gaped core. The increased leakage inductance in the primary and secondary of LLT transformer can be impacted on the DC voltage gain characteristics of LLC series resonant converter, In this paper, DC gain characteristics and the experimental results of the LLC series resonant converter with a LLT transformer are verified on the Math-CAD simulation based on the theoretical analysis and the 600W experimental prototype.

This study analyzed the conflict plots of the top 5 most watched TV series during the 2000-2005 period. It was observed that those popular series typically took love and success as main subject matters to actually aim for such a sensitive social issue as the widening gap between the rich and the poor as well as audience's desire for higher status. They even dared to describe our lives at home and the job as power relationships to heighten the intensity of the conflict. On the other hand, the resolution took a wide variety of both positive and negative endings - ranging from marriages and conciliations to death and arrests - as a way to have the antagonists punished. The deus-ex-machina was often used. A chronological view of the change in the conflict plots of successful dramas should deserve further academic interests.

As with all narrative forms based on media, the narrative method of TV human documentary is closely related to the change of broadcasting environment. In 2017, the world's first terrestrial UHD broadcast was launched in Korea, and in September of that year, KBS broadcasted the UHD special documentary series. , made of UHD capable of ultra-high definition video and immersive audio, showed a narrative approach completely different from the existing TV human documentary. Instead of all-out narration, which was considered an essential element in the TV human documentary, it used the modest first-person narration of the characters, while actively using drones capable of various compositions to express the psychology of the characters in detail and enable viewers' immersion. In addition, the Montage editing technique, an editing method that has not been attempted in TV human documentaries, utilizes the narrative development method of 'showing' as a video without 'explaining' with narration. After , many similar narrative documentaries are broadcast, and the flow and direction of TV human documentaries are changing under UHD broadcasting environment.
