Video podcasts become one of the digital content included in a combination format, combined writing, video, and audio packed so that it becomes content distributed in digital format. The ease of accessibility of podcast video content makes it important to apply media literacy to remain critical of the message's various meanings in the content in the video podcast. This study aims to determine the level of media literacy through video podcasts among students of Communication Sciences Yogyakarta. The method used in this study is a descriptive quantitative method with the concept of measuring individual competence framework media literacy. Samples from this study were active students of Communication Sciences in 2019/2020 at Ahmad Dahlan University, Mercu Buana University Yogyakarta, and AMIKOM University Yogyakarta, with a total sample of 368 respondents. This study showed that the level of media literacy through video podcasts among students of Communication Science Yogyakarta is at a high level (advanced) with details of technical skills are in the advanced category of 80%, critical understanding ability at the advanced level of 86%. Communicative abilities are at the medium level of 59%. This shows that Yogyakarta communication students can use very high media, analyze excellent information, and participate and communicate actively through social media.

The questions of the necessity to develop a social network are considered. The developed social network is offered for publishing new posts, adding and removing other members from the friends list, personal correspondence with any member. Particular attention is paid to the issues of using video content and the reasons for the popularity of video content are determined. A simple and user-friendly design is proposed to accomplish the task. The functions of the user in the developed system are considered and the use cases diagram is constructed. The social network database is described. The choice of the PHP programming language for the task implementation is analyzed and substantiated. Features of use and advantages of Open Server and Bootstrap framework are considered. The use in the development of the social network Ajax - the technology of developing web-applications has been substantiated. The work of the developed social network on the part of the user and the administrator are described. Particular attention is paid to the authorization of the user on the network, for the safety of pages. The test results are presented to check the system's correctness and the compliance of its implementation with the requirements. The project has been uploaded to shared hosting, which makes the social network ready for use on the Internet

Road network performance (RNP) is a key element for urban sustainability as it has a significant impact on economy, environment, and society. Poor RNP can lead to traffic congestion, which can lead to higher transportation costs, more pollution and health issues regarding the urban population. To evaluate the effects of the RNP, the involved stakeholders need a real-world data base to work with. This paper develops a data collection approach to enable location-based RNP analysis using publicly available traffic information. Therefore, we use reachable range requests implemented by navigation service providers to retrieve travel times, travel speeds, and traffic conditions. To demonstrate the practicability of the proposed methodology, a comparison of four German cities is made, considering the network characteristics with respect to detours, infrastructure, and traffic congestion. The results are combined with cost rates to compare the economical dimension of sustainability of the chosen cities. Our results show that digitization eases the assessment of traffic data and that a combination of several indicators must be considered depending on the relevant sustainability dimension decisions are made from.

The Lord’s Prayer is a central text in Christian liturgy, generally recited rather than sung, often as a communal act of worship. The text has also provided inspiration for many musical settings, a process of ‘musicking’ [musikierung] which takes the text out of its traditional worship environment. The internet – and specifically video-streaming sites such as YouTube – are now providing a medium for the dissemination of stage, screen, studio and audio performances of the Lord’s Prayer as song, and these are now reaching – and speaking to – new audiences up to eighty years after they were made; the fact that individuals continue to post video and audio content of the Lord’s Prayer as song reflects their desire to share something which has moved them, whether musically or spiritually, with a worldwide audience.In liberating the text from its liturgical context and releasing it as song into classical, jazz, rock, and pop performance arenas, many questions are raised about the transformation of textual meaning and ritual significance. The aim of this study is to examine the meaningfulness of the musico-textual setting for the receiver, firstly through the question of ownership of the text as a communal prayer, and secondly in arguing that perception and reception of the performer are contributory factors in the relative positivity or negativity of the receiver’s response. The research was carried out by examining a selection of the legion twentieth- and twenty-first-century musical settings of the Lord’s Prayer readily accessible through YouTube, using ethnographic data from on-line comments and from the author’s on-line survey of Christian worshippers to explore the issues raised by these musical settings. These include the perceived right of an individual to ‘perform’ a mutually-owned prayer; the loss of ritual functionality engendered by the ‘musicking’ of the text and its release into the popular domain; and the additional layers of meaning afforded to the text by gestures in performance, which can in turn lead to a transformation and renewal of ritual significance for the receiver. The inclusion of hyperlinks to YouTube video content throughout the article encourages the reader to engage with the performances themselves, from which it is hoped that a fruitful discussion of the issues will emerge.

In cellular networks, spectral efficiency is a key parameter when designing network infrastructure. Despite the existence of theoretical model for this parameter, experience shows that real spectral efficiency is influenced by multiple factors that greatly vary in space and time and are difficult to characterize. In this paper, an automatic method for deriving the real spectral efficiency curves of a Long Term Evolution (LTE) system on a per-cell basis is proposed. The method is based on a trace processing tool that makes the most of the detailed network performance measurements collected by base stations. The method is conceived as a centralized scheme that can be integrated in commercial network planning tools. Method assessment is carried out with a large dataset of connection traces taken from a live LTE system. Results show that spectral efficiency curves largely differ from cell to cell.
