As social media are emerging as essential communication channels for corporates in all areas, luxury jewelry brands have implemented enhanced strategies for brand story videos by creating brand channels on YouTube. In this study, a comparative analysis of the videos made available by Cartier and Tiffany&Co. on their YouTube Brand Channels was conducted, with the aim of identifying their strategic characteristics. The research method encompassed, both literature review and empirical investigations. A quantitative analysis was conducted by means of the 'HEART' model, a type of luxury jewelry brand story, and the following common strategic elements were identified. First, in their brand story videos both brands focus primarily on 'theme'. Second, 'relationship' and 'artisanship' are emphasized in addition to 'theme'. Third, the videos incorporate high level aesthetics to stimulate the fantasies and dreams of their audiences. The strategic differences between the brands are as follows. : First, 'artisanship' is given the greatest significance along with 'theme' in Cartier videos, while 'relationship' has prime significance in Tiffany&Co. videos. Second, a difference between a European approach and an American approach towards luxury brand building is evident, with Cartier hosting exhibitions while Tiffany&Co. provides gala videos instead.

This study analyzed the travel characteristics of Gangneung's Gyeongpo District and user reactions by utilizing YouTube videos. The findings were as follows: First, the most frequently visited places by YouTube video producers in Gyeongpo District were Gyeongpo Lake (55%) and Gyeongpo Beach (28%). In particular, videos featuring walks along the lake and beach paths were prominent, regardless of the season. Second, YouTube video producers predominantly enjoyed solo travel to Gyeongpo Lake (69%) and Gyeongpo Beach (71%), with notably few visits to historical sites. Third, viewers who watched YouTube videos related to Gyeongpo District preferred videos under 10-15 minutes in duration. Comments typically focused on "photos," "information," "solo travel," "hotels," and "healing," with positive evaluations of scenery and accommodations. Fourth, the top nine YouTube videos with the highest view counts were produced by individuals, with limited responses to videos produced by local governments or authorities. The findings identified popular tourist destinations and trends in the Gyeongpo District, noting a bias in visits and behaviors of video producers toward specific locations. This suggests the need to develop tourism resources by utilizing the natural and historical assets of Gyeongpo District. The findings are expected to guide future tourism policies, promotional efforts, and marketing strategies for Gyeongpo District.

Objective: Previous studies suggested the potential influence of YouTube videos regarding dentistry on the mass population. However, there was not any clear investigation for Korean population. We aimed to systemically analyze the type of the dentistry-related videos uploaded on YouTube Korea and the accounts used for uploading, and to assess their effect on the view count of the content. Methods: Classification, type of the accounts, and view count of the videos listed by the keyword 'dentistry' were analyzed, which were uploaded on YouTube Korea platform from September 2017 to April 2019. Kruskal-Wallis test with post hoc analysis was used to assess the effect of the classification of the videos and the type of accounts on the view count. Results: 1.026 videos were enrolled to the analysis. Primary classification of the videos was information/education, advertisement, life, news, child contents, autonomous sensory meridian response, broadcast, cartoon/game, humor, and music. Secondary classification of the videos was dental experience, advertisement, role-playing, information/education., humor, cartoon/game, child contents, life, and broadcast. Type of the accounts was dentistry associates, general public, media company, and government office (sorted by frequency). Subject of the most videos (93.6%) was general public. There was statistically significance in the view count of the videos according to the primary and secondary classifications, the account used for uploading, and target subject of the videos. Conclusion: Dentists and their associates should recognize the importance of YouTube platform and try to monitor and intervene the dentistry-related contents, considering its huge impact on the general public.

Study Design: Cross sectional study. Purpose: To assess the quality of anterior cervical discectomy and fusion (ACDF) videos available on YouTube and identify factors associated with video quality. Overview of Literature: Patients commonly use the internet as a source of information regarding their surgeries. However, there is currently limited information regarding the quality of online videos about ACDF. Methods: A search was performed on YouTube using the phrase 'anterior cervical discectomy and fusion.' The Journal of the American Medical Association (JAMA), DISCERN, and Health on the Net (HON) systems were used to rate the first 50 videos obtained. Information about each video was collected, including number of views, duration since the video was posted, percentage positivity (defined as number of likes the video received, divided by the total number of likes or dislikes of that video), number of comments, and the author of the video. Relationships between video quality and these factors were investigated. Results: The average number of views for each video was 96,239. The most common videos were those published by surgeons and those containing patient testimonies. Overall, the video quality was poor, with mean scores of 1.78/5 using the DISCERN criteria, 1.63/4 using the JAMA criteria, and 1.96/8 using the HON criteria. Surgeon authors' videos scored higher than patient testimony videos when reviewed using the HON or JAMA systems. However, no other factors were found to be associated with video quality. Conclusions: The quality of ACDF videos on YouTube is low, with the majority of videos produced by unreliable sources. Therefore, these YouTube videos should not be recommended as patient education tools for ACDF.

Videos for 360-degree virtual reality (VR) systems have a large amount of data because they are made with several different videos from multiple cameras. To store the VR data in limited space or to transmit it through a channel with limited bandwidth, the data need to be compressed at a high ratio. This paper focuses on the compression efficiency of VR videos for good visual quality. Generally, 360-degree VR videos should be projected into the planer format to cope with modern video coding standards. Among various projection schemes, three typical schemes (equirectangular, line-cubic, and cross-cubic) are selected and compared in terms of compression efficiency and quality using various videos.

As deep learning technologies becoming developed, realistic fake videos synthesized by deep learning models called "Deepfake" videos became even more difficult to distinguish from original videos. As fake news or Deepfake blackmailing are causing confusion and serious problems, this paper suggests a novel model detecting Deepfake videos. We chose Residual Convolutional Neural Network (Resnet50) as an extraction model and Long Short-Term Memory (LSTM) which is a form of Recurrent Neural Network (RNN) as a classification model. We adopted cosine similarity with hinge loss to train our extraction model in embedding the features of Deepfake and original video. The result in this paper demonstrates that temporal features in the videos are essential for detecting Deepfake videos.

With the recent popularity and technological development of online streaming video, interactive digital narrative (IDN hereafter) videos became one of the main formats for users. The current study proposed that the level of interactivity of IDN videos influences users' evaluation of the video. The concept of flow was introduced as a mediating variable between interactivity and the users' evaluation. Further, the type of IDN videos, users' familiarity with IDN videos and trust toward platforms were employed as moderating variables. Data from a survey verified the mediating role of flow, moderating role of users' familiarity and trust toward platforms. the type of IDN videos, users' familiarity with IDN videos and trust toward platforms. We have observed a significant moderating effect of users' trust toward the platform on users' evaluation resulting from flow experience. It is evident that the higher the level of users' trust towards the platform, the less pronounced the impact of flow experience on users' evaluation. Theoretical and managerial implications are discussed.
