Evaluation of Feasibility and Acceptability of a Text-Messaging Intervention for Tobacco Cessation in India.

The aim of our study was to assess the feasibility and acceptability of a brief behavioral intervention for tobacco cessation delivered via mobile phone text messaging in India. We conducted an uncontrolled intervention cohort study in adult current users of tobacco. The participants received intervention messages on their mobile phones for eight weeks. We collected qualitative data about participants' perceptions of intervention delivery and receipt, acceptability, and feasibility of the intervention. The outcomes measured at 3 months post-recruitment were self-reported 7- and 28-day point-prevalence abstinence, and Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) risk categories for tobacco-low (0-3), moderate (4-26), and high (≥27). We recruited 26 eligible participants, and 22 completed the outcome assessments. The participants generally perceived the intervention content to be simple to access and useful in facilitating a change in tobacco use. None of the participants indicated that they wanted to discontinue receiving the intervention messages. Some suggestions for enhancing acceptability included supplementing text messaging with more intensive counseling and the use of multimedia content. Eighteen percent of participants reported abstinence in the past 7 and 28 days. A greater proportion of those who used smokeless tobacco were abstinent at follow-up compared to those who smoked (42.9% vs. 6.7%; p = .04). If effective, simple and low-cost mobile phone text messaging can be used to deliver interventions for tobacco use, and has the potential to be scaled up so it can be delivered to populations of smokers interested in receiving cessation support. Our study is an important step towards the development of a contextually relevant intervention suited for low- and middle-income countries and which is responsive to the needs of both those who use smoked and smokeless tobacco. If found to be effective, our intervention would be a scalable solution to overcome the human resource related barrier to accessing tobacco cessation services in low resource settings.

A review on video summarization techniques

The exponential growth of technology has resulted in a profusion of advanced imaging devices and eases internet accessibility, leading to an increase in the creation and use of multimedia content. Analyzing representative or meaningful information from such massive data is a time-consuming task that impacts the efficiency of various video processing applications, including video searching, retrieval, indexing, sharing, and many more. In literature, numerous video summarization techniques which extract key-frames or key-shots from the original video to generate a concise yet informative summary have been proposed to address these issues. This paper presents a discussion of the state-of-the-art video summarization techniques along with limitations and challenges. The paper examines summarization techniques in a holistic manner based upon the distinct attributes of evolving video data types on the basis of parameters such as the number of views, dimensions, modality, and content. Such a categorization framework enables us to critically analyze the recent progress, future directions, limitations, datasets, application domains etc., in a better comprehensible manner.

An efficient multimedia compression-encryption scheme using latin squares for securing Internet-of-things networks

The security of multimedia content and its applications have become a a very important task in digital communication technology. The extensive use of multimedia content over wireless networks makes the network applications exposed to different types of attacks. Cryptography is one of the main technologies that provide security and confidentiality to prevent unauthorised data access. A suitable design of an encryption system must be chosen to fully secure and maintain the privacy of data. On the other hand, the large size of data will be the prominent issue. In order to maintain a better performance of Internet-of-Things (IoT) applications, an appropriate compression-encryption scheme has to be used to ensure security and high speed without increasing the cryptosystem complexity in order to achieve a large communication capacity. Therefore, this paper presents a hybrid scheme of H.264/MVC compression and encryption process based on Latin Square Cipher (LSC) using symmetric keys. The Latin Square Whitening and Latin Square Substitution and Permutation operations are included in the encryption algorithm. The simulation results and analysis on different RGB video frames using MATLAB show that the proposed scheme achieves high protection, integrity, and security performance for different transmitted video frames. In addition, high robustness against different network attacks is achieved compared to the state-of-the-art algorithms.

Multiply distorted image quality assessment based on feature level fusion and optimal feature selection

No reference image quality assessment (NR-IQA) has received considerable importance in the last decade due to a rise in the use of multimedia content in our daily lives. Due to limitations in technology, multiple distortions may be introduced in the images that need to be assessed. Recently feature selection has shown promising results for single distorted NR-IQA and their effectiveness on multiple distorted images still need to be addressed. In this paper, impact of feature level fusion and feature selection on multiple distorted image quality assessment is presented. To this end features are extracted from multiple distorted images using six NR-IQA techniques (BLIINDS-II, BRISQUE, CurveletQA, DIIVINE, GM-LOG, SSEQ) that extract features in different (discrete cosine transform, spatial, curvelet transform, wavelet transform, spatial and gradient, spatial and spectral) domains. The extracted features from different domains are fused to generate a single feature vector. All combinations of feature-level fusion from six different techniques have been evaluated. Three different feature selection algorithms (genetic search, linear forward search, particle swarm optimization) are then applied to select optimum features for NR-IQA. The selected features are then used by the support vector regression model to predict the quality score. The performance of the proposed methodology is evaluated for two multiple distorted IQA databases (LIVE multiple distorted image dataset (LIVEMD), multiply distorted image database (MDID2017)), two singly synthetically distorted IQA databases (Tampere image database (TID2013), Computational and subjective image quality database (CSIQ)), and one screen content IQA database (Screen content image quality database (SIQAD)). Experimental results show that the fusion of features from different domains gives better performance in comparison to existing multiple-distorted NR-IQA techniques with SROCC scores of 0.9555, 0.9587, 0.6892, 0.9452, and 0.7682 on the LIVEMD, MDID, TID2013, CSIQ, and SIQAD databases respectively. Moreover, the performance is further improved when the genetic search feature selection algorithm is applied to fused features to remove the redundant and irrelevant features. The SROCC scores are improved to 0.9691, 0.9723, and 0.6897 for LIVEMD, MDID, and TID2013 databases respectively.

Bringing Earth Observation to Classrooms—The Importance of Out-of-School Learning Places and E-Learning

Viewing the Earth from above has fascinated people at least since the Apollo mission in the 1960s. Today, satellite images have made their way into the news and media, but the potential of using satellite images in the classroom has not yet been exhausted. Teachers often lack the technical knowledge of Earth observation (EO) or the technical requirements in schools. The Geo:spektiv e-learning platform used provides the opportunity to integrate EO into curricula as well as current environmental- and space-relevant topics. This study analyses the driving forces that determine the motivation of students and which factors contribute to the success of an e-learning platform. The basis for this study is a Geo:spektiv module about the endangered rainforest, established at an out-of-school learning place and designed for students in secondary education. A survey of 281 students on their motivation and learning behavior showed, that in addition to the topic and level of difficulty tailored to the students’ needs, the design of the modules, simple navigation, and the use of multimedia content are vital. Despite the small sampling size and restricted geographical location of sample selection, the results of this study can contribute to better integration of digital geo-media in school lessons.

A Computer-Based Tutor to Teach Nursing Trauma Care That Works as an Adjunct to High-Fidelity Simulation.

Educators are challenged to prepare nurses to care for low-frequency, high-stakes problems such as trauma. Computer-based tutors provide a cost-effective teaching strategy without risking patient safety. Evidence for the efficacy of this type of instruction is limited; thus, we tested the learning outcomes of a tutor on trauma care knowledge with senior nursing students. Participants were randomly assigned to either the tutor or a control condition (textbook learning). Instructional design elements incorporated into the tutor included use of multimedia content, emphasis of key points, frequent quizzing with instant feedback, and unfolding case studies to summarize key concepts. Use of the tutor led to a larger increase in trauma nursing knowledge than use of a textbook. In addition, the knowledge was retained as well as book-based learning. The effect size of the tutor, 1.15, was relatively high as well-the average for computer tutors is 0.79. Qualitative focus groups revealed that participants expressed favorable views of the tutor in comparison to textbook learning. They found it more engaging and more enjoyable and reported that it effectively organized the content. The results of this study support the efficacy of a well-designed computer-based tutor for learning key concepts of trauma nursing.

Estimation of Video Streaming KQIs for Radio Access Negotiation in Network Slicing Scenarios

The use of multimedia content has hugely increased in recent times, becoming one of the most important services for the users of mobile networks. Consequently, network operators struggle to optimize their infrastructure to support the best video service-provision. As an additional challenge, 5G introduces the concept of network slicing as a new paradigm that presents a completely different view of the network configuration and optimization. A main challenge of this scheme is to establish which specific resources would provide the necessary quality of service for the users using the slice. To address this, the present work presents a complete framework for this support of the slice negotiation process through the estimation of the provided Video Streaming Key Quality Indicators (KQIs), which are calculated from network low-layer configuration parameters and metrics. The proposed estimator is then evaluated in a real cellular scenario.

Mogućnosti primjene multimedijalnih sadržaja i Interneta u nastavi Islamske vjeronauke

Islamic religious education is a school subject of educational and educational character, equally. Some of the elements of this subject's materials that could be enhanced by the use of multimedia content and the Internet are: learning Arabic in prayer, learning to perform religious rites, learning lessons from the history of Islam, familiarizing with religious culture and tradition and ways of marking Islamic holidays and checking the acquired knowledge . The paper describes the possibilities of applying IT in the learning of the mentioned material elements, with emphasis on the use of multimedia teaching materials and the Internet. First of all, the way of using PowerPoint presentations in the processing of materials is presented. These presentations are often used in teaching, and have the ability to insert images, audio and video content and create e-tests of knowledge. Prayer learning can be enhanced through the Quran audio and video that can be found on multimedia CDs and on the Internet. One way to properly learn prayer is to overcome the Arabic letter and to learn prayers written in Arabic. Learning Arabic script allows various applications enriched with animation and sound. Execution of religious rituals can be learned using web pages that contain images, audio and video content, as well as video tutorials. Learning lessons from the history of Islam is facilitated by lectures by eminent experts, which can be found on the Internet in the form of text, audio and video. There are also a number of feature and animated films about events from the history of Islam. Getting acquainted with religious culture and tradition and ways of celebrating Islamic holidays can be done more successfully with the help of texts from official websites of Islamic communities from the surrounding area and viewing videos of celebrating Islamic holidays. Examination of acquired knowledge for some areas of Islamic religious education can be done with the help of electronic knowledge tests, which enable self-testing. Specific examples are given for the above mentioned ways of using multimedia content and the Internet. It has also been suggested the development of advanced software for self-test of the success of learning the prayer in the Arabic language.

Decision fusion-based approach for content-based image classification

PurposeCurrent practices in data classification and retrieval have experienced a surge in the use of multimedia content. Identification of desired information from the huge image databases has been facing increased complexities for designing an efficient feature extraction process. Conventional approaches of image classification with text-based image annotation have faced assorted limitations due to erroneous interpretation of vocabulary and huge time consumption involved due to manual annotation. Content-based image recognition has emerged as an alternative to combat the aforesaid limitations. However, exploring rich feature content in an image with a single technique has lesser probability of extract meaningful signatures compared to multi-technique feature extraction. Therefore, the purpose of this paper is to explore the possibilities of enhanced content-based image recognition by fusion of classification decision obtained using diverse feature extraction techniques.Design/methodology/approachThree novel techniques of feature extraction have been introduced in this paper and have been tested with four different classifiers individually. The four classifiers used for performance testing were K nearest neighbor (KNN) classifier, RIDOR classifier, artificial neural network classifier and support vector machine classifier. Thereafter, classification decisions obtained using KNN classifier for different feature extraction techniques have been integrated by Z-score normalization and feature scaling to create fusion-based framework of image recognition. It has been followed by the introduction of a fusion-based retrieval model to validate the retrieval performance with classified query. Earlier works on content-based image identification have adopted fusion-based approach. However, to the best of the authors’ knowledge, fusion-based query classification has been addressed for the first time as a precursor of retrieval in this work.FindingsThe proposed fusion techniques have successfully outclassed the state-of-the-art techniques in classification and retrieval performances. Four public data sets, namely, Wang data set, Oliva and Torralba (OT-scene) data set, Corel data set and Caltech data set comprising of 22,615 images on the whole are used for the evaluation purpose.Originality/valueTo the best of the authors’ knowledge, fusion-based query classification has been addressed for the first time as a precursor of retrieval in this work. The novel idea of exploring rich image features by fusion of multiple feature extraction techniques has also encouraged further research on dimensionality reduction of feature vectors for enhanced classification results.

Stakeholder analysis for future use of the ultra-high frequency (UHF) band

Changes in media consumption and growing use of video on-demand services are challenging the traditional media service delivery mechanisms. Linear over-the-air television service operating in the ultra-high frequency (UHF) broadcasting band is no longer sufficient to meet the changing demand. Growing mobile use of multi-media content is putting pressure on mobile broadband networks to support high data rates for large numbers of simultaneous users. Policy-makers in Europe are discussing more flexible use of the UHF band between broadcasting and mobile broadband services for more efficient media delivery. This paper explores the future use of the UHF band through strategic management of stakeholders. We identify key stakeholders, analyse their partner networks and evaluate their salience using power, legitimacy and urgency attributes. The developed stakeholder analysis helps to reach a long-term compromise and reveals the emergence of a new role for flexible use of the UHF band between broadcasting and mobile communication sectors.

Psychological prerequisites and effects of using multimedia content in the mass media

IntroductionMultimedia technologies have increased during the last decade. They have expanded their reach tremendously and have entered our everyday lives. Currently, such spheres as tourism, learning, computing and business are widely using multimedia in various projects. However, the entertainment sphere is now the main user of multimedia. Gaming and cinema industries are relying greatly on multimedia effects and exploring the new possibilities of virtual reality. Some scholars see this trend as a consequence of multimedia having a strong emotional charge and affecting the potential user with various expressive means (Shlykova, 2004).However, multimedia technologies can be used for more than just entertainment purposes. The use of multimedia content in the mass media proves this point. Today, various media outlets turn to multimedia genres to convey various meanings and present complex matters in an easy, compelling way. The various psychological effects multimedia might have on the audience have not been thoroughly studied and remain a grey area in research. Therefore, in this theoretical article, we will try to outline the general psychological effects that multimedia products might have on the users and give a theoretical explanation of these effects. We will try to prove that multimedia works have a greater potential than being only entertainment tools, as their nature is closely connected with some specific features of human perception. The article will also provide an overview of the existing psychological research in the sphere of multimedia. The main focus of the paper, however, is the use of multimedia in various media outlets.Current psychological research trends in the sphere of multimediaThe general lack of research in some aspects of multimedia psychology does not indicate that psychologists have completely ignored the phenomenon. During the last few decades, when multimedia became a wide-spread technology, psychological studies have focused mainly on how multimedia systems may be used to acquire better educational outcomes and help learning. A pioneer in this sphere is the California University professor Richard Mayer, who developed the so-called cognitive theory of multimedia learning, which is based on three key points:* Human beings have two main channels for processing information (auditory and visual)* Each of these channels has a limited carrying capacity* The learning process is an active process of filtering, selecting, organizing and integrating information. (Mayer, 2001)Based on experiments, Mayer proves that humans memorize information better if it is coded not only in words but also in visual images. Additionally, he distinguished another regularity, which he called the principle of modality, which states that the efficiency of information assimilation is greater if data are delivered as a combination of graphic images and verbal narrative, compared to being coded as graphic images and print text.Mayer's studies explain why multimedia is considered to be an effective tool in the education sphere. He argues that multimedia products stimulate an integral processing of verbal and iconic information in the working memory of humans. The integral processing requires that graphic and verbal information is delivered to the working memory simultaneously (Mayer, 2001).Mayer's legacy is used and developed by many contemporary scholars. Various studies have been performed in the sphere of educational psychology. Some of them try to build on the cognitive theory of multimedia learning (Bartlett & Strough, 2003; Bower, 2004; Koeber, 2005; Windell, Wiebe & others, 2006; Mitchem, Koury, Fitzgerald & others, 2009; Eysink, Jong, Berthold & others, 2009; Chen & Catrambone, 2014), and others are exploring the way people with various learning problems and diseases can benefit from multimedia (Wissick, 1996; Hagiwara & Smith Myles, 1999; Tjus, Heimann & Nelson, 2001; Elder-Hinshaw, Manset-Williamson, Nelson & others, 2006; Morrow, D'andrea, Stine-Morrowo Kennedy, Deshler& Wills Lloyd, 2015)During the last decade, multimedia systems have become more complex and sophisticated, which forced many scholars to develop methods to construct efficient multimedia products. …
