This study conducted a comprehensive analysis and evaluation of library services using YouTube through content analysis of YouTube content and emotional response analysis of user comments. This study analyzed 2,169 YouTube contents and 6,487 comments of users from 61 university libraries. The results showed that the number of 'data' content was the largest among 4 categories, followed by 'communication' and 'education' content, and 'promotion' content. Among the sub-classifications, the number of 'information services' contents was the largest. In the analysis of users' emotional responses to YouTube content, the major categories of users' emotional responses were 'data' content and 'communication' content. Most of the user's emotional responses were positive in all categories of content, and the most frequent user emotional expression was 'good'. In addition, the vocabulary used in the user's emotional response was more about the person appearing in the video than the expression of the content of YouTube contents.

This study examines the interaction effects between branded contents' ending types(happy ending, non-happy ending) and the level of product involvement(high involvement, low involvement) on consumer's negative responses. Results suggest that the level of product involvement had no significant effect on consumer responses since product on video clips was not closely linked to the contents' message. Selective empathy is identified as the happy ending type of branded contents had a greater effect on consumer's negative responses than the non-happy ending type of. It is an apparent new phenomenon shown among the young after 2000s. Moreover, the interaction between contents' ending types and the level of product involvement had a significant effect on consumer's negative responses. Two interaction terms (i.e. happy ending and low product involvement; non-happy ending and high product involvement) are the viable message strategies to weaken the consumer responses in terms of 'dislike'.

Various types of digital displays from PC monitor up to smart watch have been developed in response to the dramatic technological progress of electronics. Accordingly, web content creators have the need to provide web contents respectively depending on the different display environments, which increases production time and costs. As a technique for overcoming this, the responsive web design method has been proposed, which means a web page with the size of the screen being adjusted depending on the types of display. Although the responsive web system is increasingly implemented in the region of contents search pages of domestic portals, there are still many cases that contents are implemented separately for PC and for mobile. In this paper, we investigate the responsive types of the web implementation of contents search pages of domestic portal, and propose an efficient new UI for responsive web to individual types of contents search pages which responsive design is not applied to.

최근 웹기술의 발전으로 접근하는 기기별로 콘텐츠를 구성하기보다는 하나의 콘텐츠를 제작해 다양한 모바일기기에서 접근하여 볼 수 있도록 제공되고 있다. 본 논문에서는 반응형 웹기술을 이용하여 관광지 소개사이트를 설계하고 구현하였다. 반응형웹을 활용하여 개발하면 이용자는 PC와 모바일기기에서 동일한 정보를 제공받을 수 있다. 본 논문에서는 지역 관광콘텐츠를 활용하여 반응형웹으로 구성하였으며, PC뿐만 아니라 모바일기기에서 뛰어난 접근성을 제공함을 확인할 수 있었다.

There has been growing academic interest in revealing the effect of 3D stereoscopic displays, mostly based on the assumption that 3D would enhance the media user's psychological experiences. A 2(Display: 2D, 3D) x 2(Arousal: High, Low) x2(Valence: Positive, Negative) within-between subject experimental design, including both psychophysiological and self-report measurements, was employed to investigate if valence and arousal of the media content interact with the 3D stereo display. The results confirmed that 3D stereo significantly enhances the viewer's skin conductance level, while no meaningful difference for HR was found across the experimental conditions. The viewer's recall memory did not differ depending on the display type either. However, the viewer experienced a greater level of presence and liking of the content when the negative content was displayed in 3D stereo in comparison with the positive content. The practical implications of the results are further discussed.

Content services on the Internet is getting attention as a new business model, selling digital content in real-time on the web. However, most of these content-based business is based on advertisement model rather than direct-payment-based business model. One of the difficulty in setting up charge-based content service is that the pricing paradigm of digital content is different from traditional pricing of products or services. The objective of this study is to empirically derive the feasible price response functions for these content services. Based on conjoint analysis of popular attributes of digital content, several price response function models were fitted against the conjoint data, using online movie viewers' preferences for different attributes of the service. Fitted function models were linear, multiplicative, exponential, attraction, and Gutenberg models. attraction model was found to be well-fit with the data for several specific combinations of attributes. Implications for pricing strategy is discussed at the end.

One of the key factors for success in fostering web-service is the supply of user-generated contents(UGCs). Technological interactivity is an environmental factor which stimulates user-content interaction, and reflects the system's capability for supporting various interactions that are allowed by a medium. The present study uses a structural equation model to investigate the influence of three components of technological interactivity-user control, synchronicity, and responsiveness-on web-services' perceived content performance. The results show that web-services' user control and synchronicity exhibited a positive relationship with the perceived efficiency of content generation; further, perceived efficiency boosts perceptions of content quality, which means that the user control and synchronicity of a web-service also have an indirect effect on perceived content quality. Additionally, responsiveness has a positive effect on perceived content quality. These findings are important for marketers and operators seeking to make their web-service successful.

초 고령사회가 전망됨에 따라 적극적인 문화향유를 즐기는 다양한 신체적 활동성이 있는 새로운 실버세대를 스마트 시니어라고 지칭한다. 이전 연구에서는 스마트 시니어의 신체적 노화나 운동능력 저하를 고려하여 제공하는 맞춤형 UI/UX 콘텐츠 서비스를 제공하였다. 또한 스마트 시니어의 인지 반응 검사를 통하여 인지적 특성 저하 요소를 파악하고 A, B, C 그룹으로 나뉘어 그룹 특성에 맞게 글자 크기, 폰트 종류, 재생 속도 등 설정을 조정하여 맞춤형 UI/UX 콘텐츠를 제공하였다. 그러나 약 180여개의 인지 반응 검사를 진행함에 따라 스마트 시니어의 집중력 저하의 문제점이 있었다. 본 논문에서는 스마트 시니어의 인지 반응 검사지와 온라인 콘텐츠에서 스마트 시니어가 활동하여 변경된 설정 값을 이용하여 유의미한 인지반응 검사지를 추출하고 인지 반응 검사지 결과를 통해 상세한 맞춤형 UI/UX 콘텐츠를 제공하는 모델을 제안한다.
