The article is about using media formats in the teaching of Russian as a foreign language (hereinafter RFL). New digital media have now become an integral part of our lives, including actively penetrating the field of education. Working with new digital formats both receptive and productive types of speech are activated in the complex. It allows studying the most effective methodological techniques for working with new formats in teaching foreign speakers, as well as those formats specifics. That makes the present work relevant and promising. The article attempts to show the main media formats used in teaching RFL, depending on the selected information channels: training podcasts, infographics and videos. The paper also contains data from a survey among foreign students on the use of educational video materials. The survey revealed increased student’s interest in incorporating new media formats into traditional classes. Special attention is paid to the video scribe format, which best combines different modes of information transmission. The results indicate the great methodological potential of media formats in RFL.

As the number of short video users continues to grow, China is embracing the "mobile vertical screen era." To satisfy users' demands for a quicker immersive experience, major platforms are adopting a vertical screen format for micro-movies and videos, particularly given the maturity of the fragmented online context, initiatives for aging media adaptation, and the trend towards younger internet users. These factors provide a prime opportunity for the development of vertical screen video formats. Many short video platforms have begun experimenting with vertical documentaries. This paper takes the vertical documentary "Talking to Strangers" as a case study to discuss its strengths and weaknesses in conjunction with the future development of vertical screen documentaries. In today's era of fragmentation, where various types of work are emerging, how to make vertical screen documentaries into refined classics is a question worth considering and discussing deeply.

Full textAbstract:
Inter-frame tampering in surveillance videos undermines the integrity of video evidence, potentially influencing law enforcement investigations and court decisions. This type of tampering is the most common tampering method, often imperceptible to the human eye. Until now, various algorithms have been proposed to identify such tampering, based on handcrafted features. Automatic detection, localization, and determine the tampering type, while maintaining accuracy and processing speed, is still a challenge. We propose a novel method for detecting inter-frame tampering by exploiting a 2D convolution neural network (2D-CNN) of spatiotemporal information and fusion for deep automatic feature extraction, employing an autoencoder to significantly reduce the computational overhead by reducing the dimensionality of the feature’s space; analyzing long-range dependencies within video frames using long short-term memory (LSTM) and gated recurrent units (GRU), which helps to detect tampering traces; and finally, adding a fully connected layer (FC), with softmax activation for classification. The structural similarity index measure (SSIM) is utilized to localize tampering. We perform extensive experiments on datasets, comprised of challenging videos with different complexity levels. The results demonstrate that the proposed method can identify and pinpoint tampering regions with more than 90% accuracy, irrespective of video frame rates, video formats, number of tampering frames, and the compression quality factor.

Online reviews have become an important source of information for consumers, significantly influencing their purchasing decisions. However, the abundance and variety of review formats, especially the mix of text, image, and video elements, can lead to information overload and hinder effective decision-making. This study investigates how different review formats and their combinations affect the perceived helpfulness of reviews. We develop a comprehensive framework to analyze the interactions between text, image, and video elements and their impact on the helpfulness of reviews. We collect and code 8693 online reviews from JingDong Mall Mallacross six product categories, including both experience products and search products, and use multiple regression analysis to test our hypotheses. Our results show that textual review elements significantly increase review helpfulness. However, their effectiveness decreases as the amount of information increases, indicating cognitive overload. Text reviews are more prone to contribute to information overload, while visual elements such as images and videos generally do not contribute to information overload in the coexistence of text, image, and video reviews. Imagery components have a minimal effect on review helpfulness. Video elements are relatively short, which may not be sufficient to convey useful information. We also find that the impact of review formats varies between experience products and search products, and that star ratings moderate the alignment of textual or imagery components with consumer expectations. We conclude that the hybrid of text, image, and video elements in online reviews plays a crucial role in shaping consumer decision-making and information overload. Our research contributes to the literature on online reviews and information overload while providing practical implications for online retailers, review platforms, and consumers to optimize review formats, star ratings, and product types to facilitate informed purchase decisions.

Full textAbstract:
Recent theoretical developments have revealed that IS’ social media strate-gies and practices of filling the social network content rise deep awareness of social media to become a push-pull factor of the certain groups’ mindset radicalization and the terrorist discourse legitimation. Furthermore, the authors’ focus revolves around the problem that articulates the fact that social media fast spread and its accessibility facilitated IS and other terrorist, extre-mist and radical movements expand their reach to a wide range of audiences around the world. Together, the present findings confirm that the Islamic State militant group’s widespread activity on social media is being powerfully weaponized and, consequently, the IS’ impact throughout the world and its successful self-marketing as a global brand is being witnessed. A further novel finding is that the Islamic State militant group’s use of social media, while presenting radical Muslim voices and exposing the atrocities of the Islamic State, targets the spread of terrorist propaganda, self-promoting, financial funding, recruiting and training TO advocates from around the world. The body of the article goes on to discuss the problem of social media use in cutting-edge technologies and novel ways to advance its full-spectrum propaganda. It is worth emphasizing that tech-savvy IS media content covers a wide range of tools with a predominance of visual forms of communication: making live broadcasts, audio and video recordings of leaders’ speeches, running educational propaganda campaigns and various instructing films, designing virtual games, etc. Noteworthy, the Islamic State group has been using social media to promote their terrorist agenda and attract a wide audience, mainly young ardent followers. The research results cast a new light on the embracement of the IS skyrocketing technological advancement in both online and social media to develop their sophisticated media strategy has led to informational and technological outreach and evolution of IS itself. In short with concluding remarks, it has been reported that the unprecedented use of social media (innovative use of advanced and easily accessed technologies, their own production quality media content, wide use of online platforms, a number of social networks and messengers, etc.), until its recent demise (in 2015 and 2017), has made Islamic State militant group at the forefront of technological advancement among contemporary terrorist groups. The crux of the problem is its media content, its nature, types and formats remain one of the most effective and efficient weapons for IS. The Terrorist Organization has developed an innovative digital communication strategy (with its hierarchy elements), which enhanced its goals-achieving in terms of radicalization, violence and the Caliphate establishment.

Full textAbstract:
With the increasing demand for digital video applications in our daily lives, video coding and decoding become critical tasks that must be supported by several types of devices and systems. This paper presents a discussion of the main challenges to design dedicated hardware architectures based on modern hybrid video coding formats, such as the High Efficiency Video Coding (HEVC), the AOMedia Video 1 (AV1) and the Versatile Video Coding (VVC). The paper discusses eachstep of the hybrid video coding process, highlighting the main challenges for each codec and discussing the main hardware solutions published in the literature. The discussions presented in the paper show that there are still many challenges to be overcome and open research opportunities, especially for the AV1 and VVC codecs. Most of these challenges are related to the high throughput required for processing high and ultrahigh resolution videos in real time and to energy constraints of multimedia-capable devices.

Full textAbstract:
<p class="AbstractText">With sophisticated multimedia technology, there is a renewed interest in the relationship between visual and auditory channels in assessing listening comprehension (LC). Research on the use of visuals in assessing listening has emerged with inconclusive results. Some learners perform better on tests which include visual input (Wagner, 2007) while others have found no difference in the performance of participants on the two test formats (Batty, 2015). These mixed results make it necessary to examine the role of using audio and video in LC as measured by L2 listening tests. The current study examined the effects of two different types of listening support on L2 learners’ comprehension: (a) visual aid in a video with input modified with redundancy and (b) no visuals (audio-only input) with input modified with redundancy. The participants of this study included 246 Spanish students enrolled in two different intermediate Spanish courses at a large Midwestern university who participated in four listening tasks either with video or with audio. Findings of whether the video serves as a listening support device and whether the course formats differ on intermediate-level Spanish learners’ comprehension will be shared as well as participants’ preferences with respect to listening support.</p>

Abstract: Steganography is the practice of concealing a secret message inside of another message. It is a form of covert communication and can involve the use of any medium like a computer file, message, image, or video within the other file, message, image or video. It is not the same as cryptography where cryptography means secret writing and steganography which is not as popular as cryptography means covered writing. Many different file formats are often used but digital images or media files are the most popular due to their most-used on the web and the large size of media files. There exist many Steganography techniques for hiding secret information in images where some of them are more complex than others. Steganography works by changing bits of useless or used data in regular computer files such as graphics, sound, and text with bits of different and invisible information. Steganography technique refers to methods in which data hiding is performed directly on every hundredths or thousandths pixel value of cover image by replacing with corresponding to letter in the alphabet in such a way that the effect of message is not visible on the cover image and unnoticeable to someone. This paper is intended to illustrate the different steganography techniques and the purpose of techniques.

Full textAbstract:
Background Videos relating to suicide are available on YouTube, but their characteristics and impacts have seldom been examined. Objective This study aimed to examine YouTube videos posted in response to a sudden spate of student suicides in Hong Kong during the 2015-2016 school year and evaluate the impacts of those videos. Methods Keyword search was performed on YouTube, and relevant videos were identified. Video typology was examined through content analysis, specifically grouping the videos by who uploaded the videos, what presentation formats were used in the videos, whether the videos were originally created by the uploaders, and whether the videos disclosed the uploaders’ personal experiences with suicide. Impacts of the videos were assessed in terms of reach (measured by view count), engagement (measured by comment count), and insights (measured as to what extent the comments to each video could reveal personal suicide risk and attitude toward help-seeking). Statistical analysis was conducted to compare the impacts of different types of videos. The 7 most impactful videos that were originally created by the YouTubers were selected for further analysis. They were compared with 7 videos uploaded by the same YouTubers right before the student suicide videos and 7 right after the student suicide videos. The comparison focused on their impacts and the network structure of the comments to those videos. Results A total of 162 relevant YouTube videos were identified. They were uploaded by 7 types of stakeholders, and the most common format was one person talking to the camera. A total of 87.0% (141/162) of the videos were originally created by the uploaders and only 8.0% (13/162) of the videos disclosed uploader personal experiences with suicide. The uploader profiles being popular or top YouTubers and the video containing disclosure of the uploader’s personal experiences were found to be significantly correlated with greater impacts (P<.001). Focusing on the 7 most impactful original videos, it is found that those videos generated more engagement, especially more interactions between the viewers, and more insights than regular videos uploaded by the same YouTubers. Conclusions When responding to a youth suicide crisis, videos made by key opinion leaders on YouTube sharing their own experiences of overcoming suicide risks could generate significant positive impacts. These types of videos offer a precious opportunity to craft online campaigns and activities to raise suicide prevention awareness and engage vulnerable youth.

Full textAbstract:
Purpose The purpose of this paper is to describe and assess Arabic videos related to cancer treatment to gain insights about the nature of health information as it is shared on YouTube. Accordingly, future strategies for different bodies are suggested to promote effective communication. Design/methodology/approach The approach is to select a representative sample of YouTube videos for certain search terms related to cancer treatment in the Arabic language. In order to identify the search terms, Google Trends is utilized. To retrieve the most relevant videos, a simple python tool is developed using YouTube API V3. For this study, the first 150 relevant videos are quantitatively and qualitatively analyzed. Objective data and subjective data are collected for each video and analyzed. Objective data include video title, URL, length, view count, like count, dislike count, comment count and the associated tags. For content analysis, coding themes are defined for the subjective data as follows: video format, video authorship and video content. Video content includes three categories: types of treatments, targeted part and evidence-based indicators. Findings The study included 150 videos, from which 30 videos were not content related; therefore, 120 videos remain in the analysis. Using rounding values, it can be observed that the average video lasted 10 min, had 184,966 views, was commented on 263 times, was liked by 2,295 users and disliked by 148 users. Non-professional individuals (46 percent) posted less than half of the videos, whereas public institutions posted only 18 percent of videos. More than half of videos (56 percent) promoted using herbal, botanical, and other natural products for cancer treatment. The majority of YouTube video formats were videos (52 percent), followed by audio with captions (30 percent). News and stories were the dominant videos, with (16 percent), and other types of videos were mostly testimonials and private centers promotions. Only 6 and 9 percent of videos targeted the genetic and immune systems, respectively. Out of the 120 analyzed videos, 86 percent did not mention any risk factor for the recommended treatment, and 73 percent did not offer the details of their usage direction. Research limitations/implications Researchers need to understand the information that is currently available on social media platforms related to the high-risk diseases in order to design initiatives, tools, and actions to allow an easy effective transfer of knowledge. Practical implications Recounting in-depth knowledge of YouTube cancer treatment contents will allow policy makers, YouTube management, medical organizations, and government agencies to understand the viewers’ behavior of YouTube and their needs to provide accurate and trustworthy information to adopt evidence-based resources. Social implications Creating the suitable content, in terms of health promotion strategies, associated with the appropriate format and understandable language that people need will be one of the major responsibilities of YouTube management, government and professional bodies. The well-designed health messages will enhance users’ engagement and attention to health issues from trusted sources. Originality/value There is very less information about Arabic messages in social media, YouTube in particular, specifically regarding cancer treatment. Thus, this study is one of the first studies to explore how Arabic messages are presented on YouTube. The aim of the assessment is to extract the current status and suggest future strategies for different bodies to have effective communication toward the Arabic communities.

Full textAbstract:
Media convergence and the incorporation of new narratives typical of the consumption habits of younger audiences in the social media environment have led to the proliferation of a wide variety of formats and types of content in the media ecosystem through which the editorial content offered to brands is being distributed. This qualitative research, using in-depth interviews with a qualified sample of branded content managers from the main Spanish media, allows us to determine the main characteristics of the native advertising demanded by advertisers. The results corroborate observations that content channelled through more sophisticated consumption experiences, using both multimedia and interactivity with a clear transmedia approach, tends to be better received by the audience and, therefore, in greater demand by brands. It also confirms that both video and social media formats have grown exponentially when it comes to providing an outlet for branded content. Based on the results obtained, a proposed classification of these products, including definitions, has been drawn up so they can be publicised to the professional world, offering the reflection and precision that their rapid development has not allowed until now.

Full textAbstract:
The variety of formats in which qualitative data may be collected have been explored within the methodological literature. Yet, the multiple options for coding these data formats have not been comprehensively detailed. While transcript analysis is widely used across disciplines, it may have limitations—particularly for research involving marginalized populations. This paper presents a multimodal coding approach as a methodological innovation for triangulating three data formats (transcript, audio, and video), detailed through the application of this analytic approach during a qualitative study exploring media engagement with sexual and gender minority youth (SGMY). Nineteen semi-structured interviews with SGMY were filmed and transcribed. Nine independent coders then utilized the innovative multimodal approach to code the three data formats using a constructivist grounded theory framework. Some codes were similar across modalities, such as those related to safety issues and finding identity and community through media. Others differed between modalities, such as those related to participant affect, perceived contradictions, discrepancies between verbal statements and body language, level of comfort and engagement, and distress when discussing traumatic experiences. Video coding captured the broadest range of emotions and experiences from marginalized youth, while transcripts provided the most straightforward form of data for coding. Multimodal coding may be applicable across qualitative approaches to enrich analyses and account for potential biases, thereby enhancing analytical lenses in qualitative inquiry. Methodological strategies for coding and integrating data types are discussed.

Abstract The presented paper is about the evaluation of products in digital styling formats, such as tutorials, hauls and tops&flops. Therein, we provide an approach to analyze specific para-interactive processes specifically addressing a teenage audience. Semiotic as well as interactional approaches are considered to demonstrate, based on video material, how YouTube influencers use multimodal potentials of various text types para-interactively to integrate their (female) recipients into the video itself. This phenomenon leads to the fact, that the audience may not only share the perception of presented products, but also, the influencers’ evaluation.

Full textAbstract:
Background Mental health is a highly stigmatized disease, especially for young people. Due to its free, accessible format, college students increasingly use video-based social media for many aspects of information needs, including how-to tips, career, or health-related needs. The accessibility of video-based social media brings potential in supporting stigmatized contexts, such as college students’ mental health. Understanding which kinds of videos about college students’ mental health have increased viewer engagement will help build a foundation for exploring this potential. Little research has been done to identify video types systematically, how they have changed over time, and their associations on viewer engagement both short term and long term. Objective This study aims to identify strategies for using video-based social media to combat stigmatized diseases, such as mental health, among college students. We identify who, with what perspective, purpose, and content, makes up the videos available on social media (ie, YouTube) about college students’ mental health and how these factors associate with viewer engagement. We then identify effective strategies for designing video-based social media content for supporting college students’ mental health. Methods We performed inductive content analysis to identify different types of YouTube videos concerning college students’ mental health (N=452) according to video attributes, including poster, perspective, and purpose. Time analysis showed how video types have changed over time. Fisher’s exact test was used to examine the relationships between video attributes. The Mann-Whitney U test was used to test the association between video types and viewer engagement. Lastly, we investigated the difference in viewer engagement across time between two major types of videos (ie, individuals’ storytelling and organization’s informational videos). Results Time trend analysis showed a notable increase in the number of (1) videos by individuals, (2) videos that represent students’ perspectives, and (3) videos that share stories and experiential knowledge over the recent years. Fisher’s exact test found all video attributes (ie, poster, perspective, and purpose) are significantly correlated with each other. In addition, the Mann-Whitney U test found that poster (individual vs organization) and purpose (storytelling vs sharing information) type has a significant association with viewer engagement (P<.001). Lastly, individuals’ storytelling videos had a greater engagement in the short term and the long term. Conclusions The study shows that YouTube videos on college students’ mental health can be well differentiated by the types of posters and the purpose of the videos. Taken together, the videos where individuals share their personal stories, as well as experiential knowledge (ie, tips and advice), engaged more viewers in both the short term and long term. Individuals’ videos on YouTube showed the potential to support college students' mental health in unique ways, such as providing social support, validating experience, and sharing the positive experience of help-seeking.

Full textAbstract:
The Versatile Video Coding (VVC) is a new standard released in 2020 and is considered the state-of-the-art technology in video coding. It introduces several innovative tools to achieve high coding efficiency, but, on the other side, requires a significantly higher computational effort. One of the innovations of the standard is the Multiple Transform Selection (MTS), which plays a crucial role in improving coding efficiency. MTS supports square and rectangular transform blocks and includes three transform types (DCT-II, DCT-VIII, and DST-VII) that can be combined in horizontal and vertical directions. As a result, VVC codecs must support a wide range of transform types and formats, making the development of hardware solutions essential to enable real-time processing. This work presents a dedicated hardware architecture for all inverse transforms in the VVC decoder. The proposed architecture performs one-dimensional transforms for all sizes supported in the VVC standard, allowing for the combination into 2D square and rectangular transforms, ranging from 4×4 to 64×64 blocks for IDCT-II and from 4×4 to 32×32 for IDCT-VIII and IDST-VII. The proposed architecture can process videos of up to UHD 8K@60fps resolution in real time, with a power consumption of 778 mW.

Full textAbstract:
Construction site visits and hands-on experiences are among the important instruments for educators in construction engineering and management to provide students with valuable knowledge and more engaging learning experiences. However, in addition to its existing logistical challenges, the COVID-19 pandemic has made site visits even more inaccessible as in-person classes and site visits moved to distant learning or got canceled. In a distance education system, conducting a physical site visit is not an easy task. This study focuses on the use of virtual site visits in construction and experiencing virtual hands-on training using immersive videos. Three types of video formats were used as the main content delivery methods in this pilot study namely, 2D flat, 360-degree, and 180-degree 3D videos. This method was adopted and tested in two courses that were previously face-to-face, which were then shifted to an online format due to the COVID-19 pandemic. The use of immersive videos gave students who would not have the ability to experience a physical site visit, the opportunity to experience the construction site environment and receive educational direction during a pre-recorded, hands-on, immersive video project. The goal of this study is to understand students’ experience with the provided technology, necessary improvement, implications for future research, and the potential implementations of this technology. A costume set of questionnaires was designed to retrieve students’ feedback on their experience which includes a comparison of different content delivery methods and four other study measures: knowledge retention, sense of presence, user experience, and overall satisfaction.

Full textAbstract:
Construction site visits and hands-on experiences are among the important instruments for educators in construction engineering and management to provide students with valuable knowledge and more engaging learning experiences. However, in addition to its existing logistical challenges, the COVID-19 pandemic has made site visits even more inaccessible as in-person classes and site visits moved to distant learning or got canceled. In a distance education system, conducting a physical site visit is not an easy task. This study focuses on the use of virtual site visits in construction and experiencing virtual hands-on training using immersive videos. Three types of video formats were used as the main content delivery methods in this pilot study namely, 2D flat, 360-degree, and 180-degree 3D videos. This method was adopted and tested in two courses that were previously face-to-face, which were then shifted to an online format due to the COVID-19 pandemic. The use of immersive videos gave students who would not have the ability to experience a physical site visit, the opportunity to experience the construction site environment and receive educational direction during a pre-recorded, hands-on, immersive video project. The goal of this study is to understand students’ experience with the provided technology, necessary improvement, implications for future research, and the potential implementations of this technology. A costume set of questionnaires was designed to retrieve students’ feedback on their experience which includes a comparison of different content delivery methods and four other study measures: knowledge retention, sense of presence, user experience, and overall satisfaction. Multiple statistical analyses were conducted on the collected data to provide both descriptive details and further insight into the study parameters and their relationship with each other and between different parameters.

Full textAbstract:
The media market is developing rapidly. Mass media on the Internet are convergent, creating and publishing photo, audio and video content along with text. Therefore, it is not surprising when, for example, newspapers/magazines create video materials, and TV channels create audio productions. The development of the worldwide Internet network has led to the fact that the mass media are constantly searching for promising platforms for the distribution of their media products and attracting new audiences. Podcasts have become increasingly popular in recent years. And it is surprising. After all, there is a trend that people want to devote less time to long texts and video materials, but at the same time they want to receive more different information, so short journalistic media products are gaining popularity. The audience on the Internet reduces their time to watch videos and read texts. But along with that, the attention and popularity of audio podcasts on media resources and on audio and video platforms is growing every year. Audio podcasts are a convenient format of audio materials for receiving relevant and interesting information while walking, doing household chores, being in transport, in the gym, etc. They are of various types and genres, on various topics and are free for the audience. Audio podcasts are recorded not only by journalists, but also by bloggers and other members of the Internet. In the study, the features of audio podcasts were considered, their history was shown, genres and types were characterized. Audio podcasts from high-quality mass media ("Suspilne", "Hromadske", "Liga", "Ukrainian Pravda", "Ukrinform", "Radio Svoboda", "NV" and "Babel") on podcast platforms were analyzed in detail. It was found that online media are increasingly producing audio materials for podcast platforms. Audio podcasts are recorded on various topics and in a variety of genres, but interviews dominate.

Full textAbstract:
The increasing variety of networks and end systems, especially wireless devices, pose new challenges in communication support for, particularly, multicast-based collaborative applications. In traditional multicasting, the sender transmits video at the same rate and resolution to all receivers independent of their network characteristics, end system equipment, and users' preferences about video quality and significance. Such an approach results in resources being wasted and may also result in some receivers having their quality expectations unsatisfied. This problem can be addressed, near the network edge, by applying dynamic, in-network adaptation (e.g., transcoding) of video streams to meet available connection bandwidth, machine characteristics, and client preferences. In this paper, we extrapolate from earlier work of Shorfuzzaman et al. 2006 in which we implemented and assessed an MPEG-1 transcoding system on the Intel IXP1200 network processor to consider the feasibility of in-network transcoding for other video formats and network processor architectures. The use of “on-the-fly” video adaptation near the edge of the network offers the promise of simpler support for a wide range of end devices with different display, and so forth, characteristics that can be used in different types of environments.

Full textAbstract:
A selective encryption algorithm is proposed to improve the efficiency of high efficiency video coding (HEVC) video encryption and ensure the security of HEVC videos. The algorithm adopts the integer dynamic coupling tent mapping optimization model as the pseudo-random sequence generator, and multi-core parallelization is used as the sequence generation mechanism. The binstrings during the process of context adaptive binary arithmetic coding are selected for encryption, which conforms to the features of invariable binstream and compatible format in terms of video encryption. Performance tests for six types of standard videos with different resolutions were performed. The results indicated that the encryption algorithm has a large key space and benefits from a high encryption effect.

With the many varied options for media presentation available within virtual reality devices today, it is important to start comparing these different formats to determine how different they are from each other. This project examined the differences between 180-Degree and 2D presentations of sports media within virtual reality headsets (HMD). Additionally, it also examined how much including individual differences helped explain participant experiences of presence, suspense, and enjoyment. Participants were asked to watch a piece of sports media footage presented either in 180-Degree or 2D formats within their own headset and then complete surveys on presence, suspense, enjoyment, team disposition, and fanship post-watching the video clip. This data was analyzed using a MANOVA and hierarchical linear regression. Results showed that there were no differences between the two types of media presentation, but fanship did help to understand more of the variance within participants’ enjoyment.

Full textAbstract:
The article is devoted to art blogging as a specific format of artistic communication, the most popular type of which is movie video blogging. It is characterized by a vivid experimental nature, the search for new creative models and new aesthetic orientations, and the borrowing of the rhetoric and aesthetics of unprofessional video bloggers by professionals, which has become one of the trends in modern professional blogosphere. The main and innovative features of art blogging include its synthetic character reflecting the integration of literature, media, everyday life, as well as visual and musical codes; the prevalence of user generated content that displaces traditional forms of film criticism and film journalism; a wide range of issues covered in the performances and a variety of communication formats; the development of its own value systems. Three types of film blogs are distinguished as belonging to a certain media platform: a. blogs on movie portals; b. authorial blogs on personal web pages in social networks and messengers; c. autonomous film blogs. Russian video blogging development is connected with YouTube video hosting. One of the important problems in analyzing movie blogs is the problem of defining new forms of creativity and aesthetics of bloggers' activities, whose popularity is high, making them opinion leaders and new intermediaries between film production and mass audience. This factor is due to several characteristics of film blogging: a. orientation towards freedom of opinion and honesty; b. interactive nature of communication providing various forms of feedback; c. entertainment, ease of presentation, playful style, humor; d. low style of speaking, colloquial nonliteral language; e. prevalence of negative criticism as a response to audience expectations.

The use of virtual tours has garnered attention as a promising method to enhance skills in various domains, including data center design. This research delves into the influence of different virtual tour modalities on the enhancement of data center design proficiency among both students and professionals. Through a comprehensive series of experiments and surveys, we investigate the efficacy of panoramic and video-based virtual tours in augmenting participants' comprehension of data center design principles, their capacity to apply these principles practically, and their overall competency in crafting efficient and reliable data centers. Our findings demonstrate a significant enhancement in data center design proficiency facilitated by virtual tours, particularly immersive and interactive formats surpassing traditional methods. Furthermore, our study uncovers the role of individual variances, such as prior expertise and experience in data center design, in modulating the effectiveness of virtual tours. These insights carry substantial implications for the evolution of pedagogical strategies in data center design education and training, advocating for the integration of virtual tour technologies into established curricula.

Abstract Amid the COVID-19 pandemic, TikTok, an emerging social media platform, has created an information hub to provide users with engaging and authoritative COVID-19 information. This study investigates the video format, type and content of the COVID-19 TikTok videos, and how those video attributes are related to quantitative indicators of user engagement, including numbers of views, likes, comments and shares. A content analysis examined 331 videos from official accounts featured in the COVID-19 information hub. As of 5 May 2020, the videos received 907 930 000 views, 29 640 000 likes, 168 880 comments and 781 862 shares. About one in three videos had subtitles, which were positively related to the number of shares. Almost every video included a hashtag, and a higher number of hashtags was related to more likes. Video types included acting, animated infographic, documentary, news, oral speech, pictorial slideshow and TikTok dance. Dance videos had the most shares. Video themes included anti-stigma/anti-rumor, disease knowledge, encouragement, personal precautions, recognition, societal crisis management and work report. Videos conveying alarm/concern emotions, COVID-19 susceptibility and severity, precaution response efficacy had higher user engagement. Public health agencies should be aware of the opportunity of TikTok in health communication and create audience-centered risk communication to engage and inform community members.

Full textAbstract:
Over the years cloud computing has seen significant evolution in terms of improvement in infrastructure and resource provisioning. However the continuous emergence of new applications such as the Internet of Things (IoTs) with thousands of users put a significant load on cloud infrastructure. Load balancing of resource allocation in cloud-oriented IoT is a critical factor that has a significant impact on the smooth operation of cloud services and customer satisfaction. Several load balancing strategies for cloud environment have been proposed in the past. However the existing approaches mostly consider only a few parameters and ignore many critical factors having a pivotal role in load balancing leading to less optimized resource allocation. Load balancing is a challenging problem and therefore the research community has recently focused towards employing machine learning-based metaheuristic approaches for load balancing in the cloud. In this paper we propose a metaheuristics-based scheme Data Format Classification using Support Vector Machine (DFC-SVM), to deal with the load balancing problem. The proposed scheme aims to reduce the online load balancing complexity by offline-based pre-classification of raw-data from diverse sources (such as IoT) into different formats e.g. text images media etc. SVM is utilized to classify “n” types of data formats featuring audio video text digital images and maps etc. A one-to-many classification approach has been developed so that data formats from the cloud are initially classified into their respective classes and assigned to virtual machines through the proposed modified version of Particle Swarm Optimization (PSO) which schedules the data of a particular class efficiently. The experimental results compared with the baselines have shown a significant improvement in the performance of the proposed approach. Overall an average of 94% classification accuracy is achieved along with 11.82% less energy 16% less response time and 16.08% fewer SLA violations are observed.

Preparing academically rich collections for access by scholars and students is challenging, costly and time consuming. Concerns for maintenance, preservation, and access are paramount. Typical of 20th century archival collections, one is likely to encounter deteriorating and brittle documents, photographic prints and negatives, and obsolete formats such as open reel audio tapes, audio cassettes and video tapes. More recent collections may also contain computer media; the proliferation of formats and media types impacts the complexity of the work in providing access, as well as the costs. Without sizeable resources, it would take years to process these collections fully, especially those rich with audio and visual materials. Taking all of this into consideration, the Archives Research Center (ARC) and Digital Services Unit (DSU) of the AUC Woodruff Library decided to investigate options for grant funding to expedite the processing and digitization of these underutilized archival collections. This essay concerns the pursuit of a Humanities Collections and Reference Resources (HCRR) grants offered by the National Endowment for the Humanities (NEH).

Full textAbstract:
Data compression is a method of reducing the size of the data file so that the file should take less disk space for storage. Compression of a file depends upon encoding of file. In lossless data compression algorithm there is no data loss while compressing a file, therefore confidential data can be reproduce if it is compressed using lossless data compression. Compression reduces the redundancy and if a compressed file is encrypted it is having a better security and faster transfer rate across the network than encrypting and transferring uncompressed file. Most of the computer applications related to health are not secure and these applications exchange lot of confidential health data having different file formats like HL7, DICOM images and other audio, image, textual and video data formats etc. These types of confidential data need to be transmitted securely and stored efficiently. Therefore this paper proposes a learning compression- encryption model for identifying the files that should be compressed before encrypting and the files that should be encrypted without compressing them.

This study aims to describe students' experiences with video-based assignments. The researchers were interested in determining how and what students thought about the video-format assignment that was assigned to them. Specifically, the objectives of this study are: 1) to categorize the types of video assignments that are commonly assigned to students by lecturers; 2) to examine the perspectives of students about the types of video assignments; and 3) to identify the primary challenges and difficulties that students frequently encounter during the production process of these video assignments. To achieve this objective, the researchers employed two data collection techniques: online surveys and interviews. More than 100 students completed the online survey using a Google Form. Subsequently, the researchers proceeded to conduct interviews with a selection of respondents derived from the summary of questionnaire respondents. The findings of this study indicated that the video assignments are mostly an individual work. Students do not perceive this type of activity as burdensome, provided that not all courses require assignments in the same format, specifically video format. The authors further elucidated that the primary challenges encountered in the production of video assignments pertain to the preparation of materials and the subsequent editing process. In short, these findings are expected to serve as the predominant determinant for implementing video assignments among students in the foreseeable future, enabling them to successfully and optimally complete such projects.

Interoperability explains how two or more systems or components exchange and process information. The heterogeneity communication mechanisms of the components (GPRS, WIFI, Bluetooth, ZigBee, etc.), transmission speed, as well as the variety of the media (sound, video, text, and image) they manage have a strong influence on the interoperability. That requires the management of the adaptation to an abstract level in order to avoid ad hoc nonreusable, and/or generalizable solutions. In this paper we propose a metamodel for architectures with heterogeneous multimedia components. It enables the description of the software architectures as a collection of components manipulating various types and formats of data, and interacting between them via specific adaptation connectors.

Future adoption of shared automated vehicles (SAVs) should lead to several societal benefits, but both automated vehicles (AVs) and ridesharing must overcome their barriers to acceptance. Previous research has investigated age differences in ridesharing usage and factors influencing the acceptability and acceptance of AVs. Further complicating our understanding of SAV acceptance, much of the public lack accurate knowledge and/or actual experience regarding AVs. In this study, we employed a 3 (age group) × 4 (video condition) longitudinal mixed experimental design to investigate age differences in anticipated SAV acceptance after viewing different types of introductory videos related to AVs (educational, experiential, or both) or currently available ridesharing provided by transportation network companies (control). Younger, middle-aged, and older adults were randomly assigned to watch (1) an educational video about SAV technologies and potential benefits, (2) an experiential video showing an SAV navigating traffic, (3) both the experiential and educational videos or (4) a control video explaining how current ridesharing services work. Attitudes toward SAVs (intent to use, trust/reliability, perceived usefulness, perceived ease of use, safety, desire for control, cost, authority, media, and social influence) were measured before and after viewing the video(s). Significant differences in how SAV attitudes changed were found between the educational and experiential video conditions relative to the control video and between different age groups. Findings suggest that educational and/or experiential videos delivered in an online format can have modest but significant improvements to their viewers’ attitudes toward SAVs—particularly those of older adults.

Full textAbstract:
This study was conducted to investigate the promotion and production strategies of local government SNS short-form content. To do so, we examined the correlation between the title and video concept of 'ChungTV,' which has the largest subscriber base among local government short-form platforms, and presented strategies for the production and promotion of local government short-form content. We chose content analysis as the research method. Through various production formats such as reenactment of government officials' daily lives, parody, experiments, vlogs, and interviews, ChungTV effectively promoted themes such as 'local special laws,' 'energy conservation,' 'investment attraction,' 'COVID-19 prevention and testing,' 'local tourism activation,' 'dialogue with residents,' and 'election interviews.' Based on this correlation analysis, we categorized ChungTV's short-form content production strategy into four categories: '① Comic presentation, ② Enhancement of entertainment, ③ Resolution of curiosity, ④ Generation of interest.' In future research, it appears necessary to conduct a comprehensive study that encompasses factors such as types of video content, content creators, editing, subtitles, subscriber numbers, and content metrics (likes, dislikes, comments).

Abstract
Objective – To evaluate the usability of WorldCat Local for undergraduate students conducting research.
Design – Usability study.
Setting – Two small, liberal arts colleges in central Minnesota.
Subjects – 13 undergraduates (7 females and 6 males).
Methods – To simulate an authentic research process, researchers created a thesis statement and a list of materials students needed to find using WorldCat Local. The students were video recorded and instructed to use the “think aloud” protocol as they worked through the list of materials to find. Researchers analyzed the recordings and evaluated the efficiency of the students’ searching processes using a rubric with scores from 1 to 5.
Main Results – Students were able to find books relevant to their topic, but had difficulty in identifying a book that their college library did not own. Students had more difficulty finding current scholarly journal articles and encyclopedias. Additionally, students had trouble distinguishing different formats in the results list.
Conclusion – The WorldCat Local results interface confused students, especially when they tried to determine the types of materials found (e.g., article, book, etc.). The students showed little understanding of relevance sorting and facets, although they did attempt to use them while searching. Despite the difficulties, the colleges will keep WorldCat Local as their discovery tool while exploring alternative options. The researchers suggest the need for future research to confirm their findings and determine what changes to the discovery tool interface would be most beneficial for the users.

But now companies are specializing in the production of these ads and incentives, taking advantage of all the modern means of magazines and broadcasting video and audio formats and even mobile internet services. Each of these companies have their own philosophy of it, some of which consider the legitimate controls in advertisements but other are to make money regardless of the appropriateness of these ads or following the controls of legitimacy and this research aims at highlighting the most important of these Islamic perspective controls which must be adhered when designing these commercials ads. Islam regulates the trade system and provides a sound guideline to its followers. It has forbidden all the malpractices being exercised in business and its advertisement. The research talks about the commercial advertisements, their types, aims and the opinions of Islamic experts about them. Besides, the research proves that advertisement is permissible according to shariah.

The article presents the results of an empirical study of the features of electoral communication in the political cluster of TikTok channels during the election of deputies of the State Duma of the Federal Assembly of the Russian Federation of the VIII convocation, which took place from September 17 to 19, 2021. Using the method of content analysis, content strategies that were used by channels of a polar political orientation were identified and characterized. Thus, pro-government channels followed a strategy that we described as “television”: an attempt to use existing formats (mainly television) on a new platform (cuttings from television interviews), a combination of emotional and rational types of argumentation (as in the course of television debates), the use of topics informational character). The channels of the opposition candidates used a personalized "user" approach: publishing video messages to users on behalf of the candidates, the emotional nature of the videos, designed to involve subscribers in communication. This approach made it possible to involve users in the electoral discussion to a greater extent, which was confirmed by the results of calculating the user involvement coefficient. At the same time, the results of the study showed that neither the pro-government nor the opposition political forces were ready to be fully involved in the creation of content and adapt it to the unique formats of the TikTok service, and in the vast majority of cases they published content previously created for other communication channels. Thus, the potential of TikTok was only half used.

Today the Internet has become an integral part of the everyday life of the younger generation, and the YouTube video hosting is one of the most visited sites among Russians aged 18 to 34. Therefore, the analysis of content, structure, and dynamics of video preferences is an important area of sociological analysis of the Russian youths interests on YouTube. The research aims at identification and description of the Russian youths interests on the basis of the analysis of their video preferences on SHAPE \* MERGEFORMAT YouTube. The authors conducted content analysis of Googles annual reports on the most popular videos on YouTube in Russia, of the content of these videos and their comments, and the analysis of quantitative indicators (likes, dislikes and views). 26 Muscovites were questioned in the format of the semi-structured interview; and two online surveys (in 2019 and 2020) were conducted, in which 340 respondents participated. The authors identified three groups of factors to analyze the dynamics of video preferences: micro-social (social-psychological, status-role and needs factors); macro-social (institutional - social, political, economic, cultural - and environmental); random. The analysis of all types of research data on the most popular video clips allowed to describe the dynamics of the youths video preferences in 2008- 2020, to show the relationship of social factors with the dynamics of the youths YouTube preferences, and that these video preferences are largely determined by individual characteristics, because the significant events in the Russian social-cultural space have little influence on the youths video preferences.

Full textAbstract:
The conversion rate is important measurable data as a metric of the effectiveness of advertising. The higher the conversion rate is, the more people who saw the advertising would take action. Many factors could affect the advertising conversion rate. In this paper, we aimed to find whether the format (video and poster) of advertising presentations impacts the advertising conversion rates among college students. The researcher designed an online survey that was distributed to college students, and respondents were asked to evaluate eight products’ ads with both video and poster types. In addition we investigated five potential factors, including the level of impact social media has on advertising, gender, preferences of activities, time spent on different advertising channels, and time from viewing the ads before buying products, that would influence people’s conversion rates. The results suggested that the conversion rates between video and poster are different ( p<0.05). However, all five elements had no correlations with the conversion rate.

In truthfully, managing and storing information and data at the Department of Transport and its units in Da Nang city is still done manually and sporadically. Currently, the majority of them still utilize paper or digitized records but still save them separately on personal computers for managing and storing information regarding infrastructure, modes of transportation, etc. (.doc, .xls, .pdf files, Autocad, Video, Audio, Images, ...). Storing, maintaining, looking up, and discovering information is greatly hampered by this. There are still inconsistencies and delays in the deployment of information reporting, management information, digitization, and the availability of exploitation channels. In line with the Ministry of Transport's strategy, information technology should be used to manage transportation activities. Organizations and units in the transportation industry across the nation have developed and implemented various specialized software to assist in managing road transport. Software solutions have offered management information, enhancing professional management effectiveness. The deploying units use each software system separately, storing and handling specialized data in various ways. When it is necessary to handle and review the information of road transport vehicles, including registration information, vehicle registration, and information about traffic safety infractions, the program does not have a connection or data sharing capabilities. To access and compare data, expert employees must look for information and data on each software system to retrieve and compare data. The specificity of the data of each transport infrastructure project is that the data is very large and has many different formats; the information is updated regularly every year according to the maintenance, renovation, and upgrading process, etc. Traditional storage and data representation, like how database management systems and management software are used, will not meet the demand. In this paper, we propose a solution to build a centralized specialized database, have a specific organizational plan according to the specific characteristics of the industry, and be able to integrate data from specialized applications to connect and unify data between authorities. This will be a platform for sharing and exploiting data for professional management between authorities in the city and the whole country. The people and state management agencies highly appreciate this solution, which has been researched and implemented experimentally in Danang City.

Full textAbstract:
The virtual courses developed by higher education institutions incorporate the video format as one of the most used resources in the delivery of their online training offer. Within the different types of audiovisual productions found in MOOCs, the introductory or presentation video of the courses has become an illustrative piece of the new edu-communicative context of distance education, when articulating, in the same work, informative, didactic, and advertising content. The objective of this research work is to study the triple communicative nature of this innovative format following a specific methodology of audiovisual textual analysis. For this, 420 videos of this type of promotional video, belonging to 105 universities and educational centres that have developed MOOC courses for the Miríadax platform, are analysed. After checking the results of the formal characteristics, content structures, discursive techniques, and audiovisual language components of the videos, it is concluded that they are mostly pieces linked to the staging style of the classroom, but that, by enriching the visual appearance of a master lesson with audiovisual resources, take advantage of the narrative, aesthetic, and creative potential of audiovisual and advertising communication to capture the attention of the student-spectator, inform about the characteristics of the courses, offer valuable educational content, and generate an image of the brand for the institution responsible for producing the course.

Full textAbstract:
Steganography is the practice of concealing information within various types of data, encompassing the embedding of confidential content like messages, images, audio, or video within a cover image. The primary objective involves hiding the secret message or image within the selected image through the utilization of the Least Significant Bit (LSB) technique. To ensure the safeguarding and security of the concealed content, the Advanced Encryption Standard (AES) Algorithm is implemented. The comparison of different image formats, each varying in text length or image size, is conducted. The algorithm's efficacy is evaluated through metrics such as Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE), with a higher PSNR value indicating a superior image quality. Steganography assumes a vital role in numerous applications, including but not limited to medical, military, One Time Password (OTP), and copyright protection. Key Words: Image steganography, LSB, Advanced Encryption Standard, PSNR Ratio, MSE

Full textAbstract:
Nowadays it is easier than ever before to produce films and videos and make them available to a worldwide audience via platforms such as YouTube, Twitter and Facebook, among others. The European Space Agency (ESA), the European Southern Observatory (ESO), the National Aeronautics and Space Administration (NASA), and other similar organisations constantly produce videos aimed at the general interested audience, and distribute them on through their social media channels. Different formats are offered such as educational, informative, news style, science stories, scientist profiles, behind-the-scenes, animations and data based animations. But which of these formats do really stick and why? A simple statistical analysis of 106 videos found on the ESA, ESO and NASA YouTube channels shows that videos based on animations and the representation of data, with little to no explanation and accompanied by music are the more popular in terms of views per month by about a factor of two compared to other types of videos. This can likely be explained by the higher entertainment value of such videos.

Full textAbstract:
CAC (Call Admission Control) plays a significant role in providing QoS (Quality of Service) in mobile wireless networks. In addition to much research that focuses on modified Mobile IP to get better efficient handover performance, CAC should be introduced to Mobile IP-based network to guarantee the QoS for users. In this paper, we propose a CAC scheme which incorporates multiple traffic types and adjusts the admission threshold dynamically using fuzzy control logic to achieve better usage of resources. The method can provide QoS in Mobile IPv6 networks with few modifications on MAP (Mobility Anchor Point) functionality and slight change in BU (Binding Update) message formats. According to the simulation results, the proposed scheme presents good performance of voice and video traffic at the expenses of poor performance on data traffic. It is evident that these CAC schemes can reduce the probability of the handoff dropping and the cell overload and limit the probability of the new call blocking.

Full textAbstract:
This study discusses the evolving trends in online advertising, diverse marketing models, and changing user needs. From the early development of the Internet, especially in the early 1990s, to the emergence of numerous advertising formats, online advertising has become an integral part of modern marketing. Different types of online advertisements, such as banner ads, pop-up ads, video ads, native ads, search engine ads, and social media ads, fulfill different needs of advertisers. In addition, the study also explores diverse marketing models for online advertising, including pay-per-click, pay-per-thousand-displays, pay-per-action, affiliate marketing, targeted ads, and video ads, which provide more choices for advertisers. In terms of user characteristics and needs, as technology continues to evolve, user reliance on mobile devices increases, the use of ad-blocking and anti-advertising technologies rises, concerns about data privacy increase, social media becomes an important channel for advertising, and data analytics and ad-tracking technologies become increasingly critical. A user’s age, gender, geographic location, interests, purchase history, device and platform, social interactions, and privacy preferences are important in creating user profiles and target market analysis. In summary, online advertising plays a key role in the modern marketplace, providing advertisers with global advertising opportunities and the need to continually adapt to market and technological changes to maximize ad effectiveness.
