Internet traffic is experiencing rapid growth, with the majority of traffic generated from video steaming, web data services and Internet of Things. As these services include the transmission of small data, such as web pages, video chunks and sensing data, data latency affects the quality of experience rather than the throughput. Therefore, this study aims to decrease latency to improve the quality of the user experience. To this end, we measure the web service delay and throughput in mobile networks. The results indicate a low quality experience for mobile users, even though mobile networks support a large throughput. We therefore propose a light-weight latency reduction scheme for the Quick UDP Internet Connections (QUIC) protocol. The proposed scheme calculates the average congestion window, which is utilized as the initial congestion window when a new connection is established. The proposed scheme is evaluated through experiments on a testbed. The results show that our scheme reduces latency significantly. The results of this study can help improve user experiences of video streaming and web data services.

The collaborative online 3D rendering system proposed in this paper ensures the quality of user experience and protects online rendering resources. In this system, the conditional generative adversarial network is used to calculate complex global illumination information instead of rendering them on cloud servers. The web front-end generates high-frequency direct lighting information in real-time and displays the final result which is a blend of front-end direct lighting information and back-end indirect lighting information. Experiments show that our proposed system can improve the rendering quality of the Web3D front-end, ensure Web-Cloud load balance, and protect rendering resources online.

Google’s Material Design, created in 2014, led to the extended application of floating action buttons (FAB) in user interfaces of web pages and mobile applications. FAB’s roll is to trigger an activity either on the present screen, or it can play out an activity that makes another screen. A few specialists in user experience (UX) and user interface (UI) design are sceptical regarding the usability of FAB in the interfaces of both web pages and mobile applications. They claim that the use of FAB easily distracts users and that it interferes with using other important functions of the applications, and it is unusable in applications designed for iOS systems. The aim of this paper is to investigate by an experiment the quality of experience (QoE) of a static and animated FAB and compare it to the toolbar alternative. The experimental results of different testing methods rejected the hypothesis that the usage and animation of this UI element has a positive influence on the application usability. However, its static and animated utilization enhanced the ratings of hedonic and aesthetic features of the user experience, justifying the usage of this type of button.

There are numerous subfields within visual communication, one of which is new media, alongside conventional practices such as advertising, photography, the web, animation, and signage. Blogs, social media, video games, email and the pervasiveness of smartphones have all resulted in the emergence of new media that are inextricably linked to the internet and the online environment. since the first mobile game, "Tetris", in 1994 and “Snakes" in 1997, the visual element in mobile games has evolved significantly, culminating in the modern-day mobile gaming world. These changes have involved progress from the black and white images of the early games to the variety of colours used in game visuals today and the creation of virtual goods in-app games. A skin is one of these virtual goods or items and is synonymous with a virtual appearance, outfit or cosmetic item that can be used to modify and enhance the appearance of a player's avatar. This is a cosmetic item and purely aesthetic in nature, serving no functional purpose. Among players, the desire for a skin is undeniable. Apart from the "beauty factor," another hidden value is inherent in players' perceptions of their interactions with purely aesthetic items. To determine the attractiveness of the skin in mobile games, preliminary research on skin evaluation was conducted to ascertain players' perceptions of recent virtual skins they had used in-game. The purpose of the study was to identify players’ perceptions of the attractiveness of the skin they used. To conduct the research, the Standard User Experience Questionnaire (UEQ) was used to determine the attractiveness of the skin as a virtual product. The UEQ is composed of six scales and twenty-six items that assess attractiveness on a hedonic and pragmatic level. Thirty respondents were chosen, and data analysis was performed using UEQ Data Analysis Tools. The product's benchmark was divided into five UX quality categories: excellent, good, above average, below average, and bad. The results indicate that stimulation is an excellent proxy for the UX quality of skin and efficiency is above average; meanwhile, attractiveness, perspicuity, dependability, and novelty were below average.

The popularity of smartphones and mobile applications has experienced a considerable growth during the recent years, and this growth is expected to continue in the future. Since smartphones have only very limited energy resources, battery efficiency is one of the determining factors for a good user experience. Therefore, some smartphones tear down connectionsto the mobile network soon after a completed data transmission to reduce the power consumption of their transmission unit. However, frequent connection reestablishments caused by apps which send or receive small amounts of data often lead to a heavy signalling load within the mobile network. One of the major contributions of this paper is the investigation of the resulting tradeoff between energy consumption at the smartphone and the generated signalling traffic in the mobile network. We explain that this tradeoff can be controlled by the connection release timeout and study the impact of this parameter for a number of popular apps that cover a wide range of traffic characteristics in terms of bandwidth requirements and resulting signalling traffic. Finally, we study the impact of the timer settings on Quality of Experience (QoE) for web traffic. This is an important aspect since connection establishments not only lead to signalling traffic but also increase the load time of web pages.

Background Self-monitoring of symptoms is a cornerstone of psychological interventions in bipolar disorder (BD), but individuals with lived experience also value tracking holistic outcomes, such as quality of life (QoL). Importantly, self-monitoring is not always experienced positively by people with BD and may have lower than expected rates of engagement. Therefore, before progressing into QoL tracking tools, it is important to explore user perspectives to identify possible risks and benefits, optimal methods to support engagement, and possible avenues to integrate QoL self-monitoring practices into clinical work. Objective This study aimed to conduct a qualitative exploration of how individuals with BD engaged with a Web-based version of a BD-specific QoL self-monitoring instrument, the QoL tool. Methods A total of 43 individuals with BD engaged with a self-management intervention with an optional Web-based QoL self-assessment tool as part of an overarching mixed method study. Individuals were later interviewed about personal experiences of engagement with the intervention, including experiences of gauging their own QoL. A thematic analysis was used to identify salient aspects of the experience of QoL self-monitoring in BD. Results In total, 4 categories describing people’s experiences of QoL self-monitoring were identified: (1) breadth of QoL monitoring, (2) highlighting the positive, (3) connecting self-monitoring to action, and (4) self-directed patterns of use. Conclusions The findings of this research generate novel insights into ways in which individuals with BD experience the Web-based QoL self-assessment tool. The value of tracking the breadth of domains was an overarching aspect, facilitating the identification of both areas of strength and life domains in need of intervention. Importantly, monitoring QoL appeared to have an inherently therapeutic quality, through validating flourishing areas and reinforcing self-management efforts. This contrasts the evidence suggesting that symptom tracking may be distressing because of its focus on negative experiences and positions QoL as a valuable adjunctive target of observation in BD. Flexibility and personalization of use of the QoL tool were key to engagement, informing considerations for health care providers wishing to support self-monitoring and future research into Web- or mobile phone–based apps.

<p class="apa">This research explored perceptions of learners studying English in private language schools regarding the use of mobile technology to support language learning. Learners were first exposed to both a mobile assisted and a mobile unassisted language learning experience, and then asked to express their thoughts on the incorporation of mobile devices into the language classroom. The mobile assisted tasks involved learners posting a review online based on a real past experience, as well as using web-search engines to gather enough information to plan a hypothetical trip. Findings revealed overall positive attitudes amongst the students surveyed. Arguments in favour of the incorporation of mobile technology in the language classroom included: the possibility of having access to a range of materials superior in both quality and quantity when using mobile devices to access the Internet, among others. However, a significant amount of scepticism towards Mobile Assisted Language Learning emerged. Arguments against suggested that the format of presentation, rather than the type of task, seemed to constitute a motivational factor that played a psychologically significant role to some of the learners.</p>

Web surveys are struggling to attract and retain respondents due to high burden and competition for the users’ attention. One possible solution to this issue is the improvement of the visual design of surveys. In this article, we evaluate the impact of visual aids such as smiley faces, stars, hearts, and thumbs as alternatives to traditional radio buttons. We use an experimental design in a nonprobability online survey to investigate how the new designs compare with radio buttons and how the results might interact with device used for completion (PC vs mobile), the use of labels, the type of response scale (bipolar vs unipolar), and the number of response categories (5 vs 7 point). While we do not find big differences in response, quality and experience, there seem to be some indication that the use of smiley faces leads to worse data quality.

This study presents a modelling approach for quantifying the Mobile Web Quality of Experience (MWQoE). It builds on current QoE and Web QoE research, and by fusing together data that is available on modern mobile devices, constructs a novel MWQoE model that is user-centered, context-aware and non-intrusive (does not depend on user feedback). This study identifies the factors which affect Web QoE and measures their effect on it in mobile scenarios. Moreover, this study explores scenarios in which Web QoE can be effectively characterized and enhanced, delivering a novel Mobile-to-Cloud system for the continuous evaluation of MWQoE in real-world environments. The significance of defining and evaluating MWQoE is identified. Specifically, MWQoE can be used by online providers to uncover customer insights and illustrate how the experience in using their products is perceived by their customers. In fact, MWQoE can be considered an important key performance indicator showing the technology acceptance or satisfiability of customers for a specific web product or service.

The web and mobile web traffic is growing rapidly due to service accessibility in densely populated areas and massive usage of smart hand held devices (smartphones, pads and Internet dongles). This is a challenge for mobile operators and service providers, because it forces systematically increasing network throughput capacity and in parallel to keep this investment on profitable basis. On the other side, the user satisfaction with mobile broadband service should be considered as well, in order to balance the user expectations and mobile operator investments. Our work provides extensive QoE study for different conditions in sense of mobile web service, web content, network conditions and end user device. Finally, the obtained results create basis for more dimensional overview of mobile web QoE and allow to recognize quality and saturation thresholds based on network parameters. Further, obtained data provide base for design three prediction models for prediction of MOS (one for notebook, one for mobile device) and acceptability.

Le trafic vidéo a subi une augmentation fulgurante sur Internet ces dernières années. Pour pallier à cette importante demande de contenu vidéo, la technologie du streaming adaptatif sur HTTP est utilisée. Elle est devenue par ailleurs très populaire car elle a été adoptée par les différents acteurs du domaine de la vidéo streaming. C’est une technologie moins couteuse qui permet aux fournisseurs de contenu, la réutilisation des serveurs web et des caches déjà déployés. En plus, elle est exempt de tout blocage car elle traverse facilement les pare-feux et les translations d’adresses sur Internet. Dans cette thèse, nous proposons une nouvelle méthode de vidéo streaming adaptatif appelé “Backward-Shifted Coding (BSC)”. Il se veut être une solution complémentaire au standard DASH, le streaming adaptatif et dynamique utilisant le protocole HTTP. Nous allons d’abord décrire ce qu’est la technologie BSC qui se base sur le codec (encodeur décodeur) à multi couches SVC, un algorithme de compression extensible ou évolutif. Nous détaillons aussi l’implémentation de BSC dans un environnement DASH. Ensuite,nous réalisons une évaluation analytique de BSC en utilisant des résultats standards de la théorie des files d’attente. Les résultats de cette analyse mathématique montrent que le protocole BSC permet de réduire considérablement le risque d’interruption de la vidéo pendant la lecture, ce dernier étant très pénalisant pour les utilisateurs. Ces résultats vont nous permettre de concevoir des algorithmes d’adaptation de qualité à la bande passante en vue d’améliorer l’expérience utilisateur. Ces algorithmes permettent d’améliorer la qualité de la vidéo même étant dans un environnement où le débit utilisateur est très instable.La dernière étape de la thèse consiste à la conception de stratégies de caching pour optimiser la transmission de contenu vidéo utilisant le codec SVC. En effet, dans le réseau, des serveurs de cache sont déployés dans le but de rapprocher le contenu vidéo auprès des utilisateurs pour réduire les délais de transmission et améliorer la qualité de la vidéo. Nous utilisons la programmation linéaire pour obtenir la solution optimale de caching afin de le comparer avec nos algorithmes proposés. Nous montrons que ces algorithmes augmentent la performance du système tout en permettant de décharger les liens de transmission du réseau cœurDue to the growth of video traffic over the Internet in recent years, HTTP AdaptiveStreaming (HAS) solution becomes the most popular streaming technology because ithas been succesfully adopted by the different actors in Internet video ecosystem. Itallows the service providers to use traditional stateless web servers and mobile edgecaches for streaming videos. Further, it allows users to access media content frombehind Firewalls and NATs.In this thesis we focus on the design of a novel video streaming delivery solutioncalled Backward-Shifted Coding (BSC), a complementary solution to Dynamic AdaptiveStreaming over HTTP (DASH), the standard version of HAS. We first describe theBackward-Shifted Coding scheme architecture based on the multi-layer Scalable VideoCoding (SVC). We also discuss the implementation of BSC protocol in DASH environment.Then, we perform the analytical evaluation of the Backward-Sihifted Codingusing results from queueing theory. The analytical results show that BSC considerablydecreases the video playback interruption which is the worst event that users can experienceduring the video session. Therefore, we design bitrate adaptation algorithms inorder to enhance the Quality of Experience (QoE) of the users in DASH/BSC system.The results of the proposed adaptation algorithms show that the flexibility of BSC allowsus to improve both the video quality and the variations of the quality during thestreaming session.Finally, we propose new caching policies to be used with video contents encodedusing SVC. Indeed, in DASH/BSC system, cache servers are deployed to make contentsclosed to the users in order to reduce network latency and improve user-perceived experience.We use Linear Programming to obtain optimal static cache composition tocompare with the results of our proposed algorithms. We show that these algorithmsincrease the system overall hit ratio and offload the backhaul links by decreasing thefetched content from the origin web servers

Mestrado em Engenharia de Computadores e TelemáticaThis Master dissertation has the aim of study, and further develop, a tool that allows to gather Quality of Experience metrics, in the Web browsing context, in order to perceive, as close to reality as possible, the experience that real users would have during the navigation in webpages. The gathering of Quality of Experience and Service metrics are essential for telecom operators, in order to diagnose the quality of services and, consequently, perceive the level of satisfaction of its clients. In this context, the solution was an application that acts independently and performs tests, that allow to infer the experience that a real user would face during the access to a webpage, through a real browser. The solution is able to: extract time metrics, information related with the Web navigation, the status of the webpage and its resources. Furthermore, it allows to con gure simple or more complex interaction test scenarios with the webpage, take screen captures during the test execution and even download all the les belonging to the webpage that were loaded. The solution was tested in order to evaluate its performance and returned values (metrics) reliability, comparing with a real navigation values.

The area of mobile web is evolving rapidly but there are still no consensus regarding recommendations or best practices within the topic. Therefore this thesis is focused on interaction design within mobile web and compiles many dierent theories into guidelines for mobileweb design. The thesis may also be used as a foundation when deciding whether to developa native mobile application or a mobile adapted web application, or when choosing betweena separate mobile web application and a responsive web design.Components that are especially considered in this thesis are form elements and navigation menus. These are discussed relative to interaction on small touch screens such as smartphones and tablets. For example, text input elements can be optimized for the intended input format and one can take advantage of the device's native components for e.g. time and date input. A prototype of a responsive web application is also developed to further exemplify the theoretical theories. This is a exploratory study for the Swedish magazine Resume in collaboration with The Mobile Life and is focused on convert the original site into a responsive design, but still retain the overall Resume look and feel.

Thanks to their increasing sophistication and popularity, mobile devices, in the form of smartphones and tablets, have become the fastest growing contributors to Internet traffic. Indeed, smartphones are projected to account for 50% of global Internet traffic by 2017, with the share of mobile video increasing to about 40% of total Internet traffic. As users embrace Internet streaming of video, several studies have found that a small decrease in video quality leads to a substantial increase in viewer abandonment and disengagement rates. To handle the explosive growth in video traffic, Adaptive HTTP streaming, which exploits the prevalence of commodity web servers and content distribution networks, has emerged as the key technology for delivering video to end users. Although a number of systems have been proposed for HTTP video streaming in traditional environments and for fixed clients, existing platforms for video streaming on mobile devices are still in their infancy and do not address the additional challenges often experienced by mobile clients: high fluctuations in network conditions, heterogeneous networking interfaces, multiple form-factors, and limited battery life.
In this dissertation, we propose a number of solutions for improving the Quality of Experience of HTTP video streaming on mobile devices. We begin by evaluating the performance of several existing video quality adaptation schemes when deployed on mobile platforms. Through experiments with smartphones in wide-area environments, we assemble several key findings. First, we show that the high fluctuations in network throughput on cellular and Wi-Fi networks impose significant challenges for efficiently architecting the video adaptation scheme. Second, we find significant differences between the performance of the current state-of-the-art schemes in controlled experimental settings and their performance in mobile settings on key quality metrics such as inefficiency, instability, rebuffering ratio, and startup latency. We also find noticeable differences in the behavior of the schemes under Wi-Fi and cellular network access, with most of the schemes performing worse when the network access is cellular. Given these observations, we hypothesize on the possible causes of these inefficiencies. We also identify the best practices of existing schemes and key insights from experimental results that can serve as foundations for addressing many of the limitations.
Armed with these measurement-driven insights, we propose a novel video quality adaptation scheme, called MASS, which is more robust to the vagaries of the wireless networking conditions. We implement and evaluate our solution on commodity Android smartphones, and demonstrate significant performance gains over existing schemes. To further improve the streaming experience, we introduce an extension to HTTP video streaming that leverages the synergy between social network participation and video streaming to optimize end-user Quality of Experience. Our system, called SDASH, integrates and applies well-known concepts such as cooperative caching, prefetching, and P2P streaming for reducing bitrate fluctuations and optimizing the viewing experience. Finally, we develop a general infrastructure for constructing temporally and spatially localized P2P communities of mobile devices sharing similar interests. The platform enables on-demand cooperation among mobile clients based on device context and client preferences. We use a concrete implementation of the mobile P2P infrastructure for evaluating the performance of SDASH.
This dissertation addresses the challenges facing Adaptive HTTP Streaming under mobile networking conditions. Through experimentation with commodity mobile devices, we show that the proposed techniques for bitrate adaptation and cooperative streaming can significantly improve the video viewing experience.

People like to consume multimedia content on mobile devices. Mobile networks can deliver mobile TV services but they require large infrastructural investments and their operators need to make trade-offs to design worthwhile experiences. The approximation of how users experience networked services has shifted from the inadequate packet level Quality of Service (QoS) to the user perceived Quality of Experience (QoE) that includes content, user context and their expectations. However, QoE is lacking concrete operationalizations for the visual experience of content on small, sub-TV resolution screens displaying transcoded TV content at low bitrates. The contribution of my thesis includes both substantive and methodological results on which factors contribute to the QoE in mobile multimedia services and how. I utilised a mix of methods in both lab and field settings to assess the visual experience of multimedia content on mobile devices. This included qualitative elicitation techniques such as 14 focus groups and 75 hours of debrief interviews in six experimental studies. 343 participants watched 140 hours of realistic TV content and provided feedback through quantitative measures such as acceptability, preferences and eye-tracking. My substantive findings on the effects of size, resolution, text quality and shot types can improve multimedia models. My substantive findings show that people want to watch mobile TV at a relative size (at least 4cm of screen height) similar to living room TV setups. In order to achieve these sizes at 35cm viewing distance users require at least QCIF resolution and are willing to scale it to a much lower angular resolution (12ppd) then what video quality research has found to be the best visual quality (35ppd). My methodological findings suggest that future multimedia QoE research should use a mixed methods approach including qualitative feedback and viewing ratios akin to living room setups to meet QoE’s ambitious scope.

To an end user, Quality of Experience (QoE) matters more than Quality of Service (QoS) because she is the owner of her experience, which is the result of her perception. In recent times, QoE got increasingly much attention from service providers, operators, manufacturers and researchers. Amongst others, they are interested to know how the users perceive the quality of multimedia streaming and how to predict the QoE by measuring network performance parameters. Below the network layer, different access networks can be used, but the internet and transport layers remain the same for everyone on best-effort internet. We highlight a set of possible factors that are contributing towards the QoE, from network via transport to application layer, including applications, codecs, middleware and devices. To investigate the relationship of QoS and QoE, emulation-based experiments were designed. For the purpose of emulation, different shapers are in use by the research community. We selected three popular shapers, NetEm, NISTnet and KauNet, and investigated their emulation capabilities with focus on delay, delay variation and bit rate in order to be able to select the best-suited shaper for future use. Then, we studied the effect of QoS parameters on mobile video QoE. To evaluate the video QoE, user tests were conducted. We observe a much larger sensitivity of users to freezes and their placement within the video than what is predicted by an objective video quality assessment tool that is recommended by the standardisation organization ITU. Furthermore, we investigated the role of codec and device on QoE in view of network-induced problems.

AbstractResearch demonstrates that positive emotions contribute to students’ greater engagement with the learning experience, while negative emotions may detract from the learning experience. The purpose of this study is to evaluate the effect of a computer-based training program on the emotional status and its effect on the performance of two students with learning difficulties: a second-grade student of a primary school with Simpson-Golabi-Behmel syndrome and a fourth-grade student of a primary school with learning difficulties. For the purpose of this study, the “BrainHQ” web-based cognitive training software and the mobile app “AffectLecture” were used. The former was used for measuring the affective state of the students before and after each intervention. The latter was used for improving students’ cognitive development, in order to evaluate the possible improvement of their initial emotional status after the intervention with “BrainHQ” program, the possible effect of positive/negative emotional status on their performance, as well as the possible effect of high/poor performance on their emotional status. The results of the study demonstrate that there is a positive effect of emotion on performance and vice versa and the positive effect of performance on the emotional status and vice versa. These findings suggest that the affective state of students should be taken into account by educators, scholars and policymakers.

AbstractThe proliferation of digital technology has swelled the amount of time people spent in cyberspace and weakened our sensibility of the physical world. Human beings in this digital era are already cyborgs as the smart devices have become an integral part of our life. Imagining a future where human totally give up mobile phones and embrace nature is neither realistic nor reasonable. What we should aim to explore is the opportunities and capabilities of digital technology in terms of fighting against its own negative effect - cyber addiction, and working as a catalyst that re-embeds human into outdoor world.Cyborgian systems behave through embedded intelligence in the environment and discrete wearable devices for human. In this way, cyborgian approach enables designers to take advantages of digital technologies to achieve two objectives: one is to improve the quality of environment by enhancing our understanding of non-human creatures; the other is to encourage a proper level of human participation without disturbing eco-balance.Finally, this paper proposed a cyborgian eco-interaction design model which combines top-down and bottom-up logics and is organized by the Internet of Things, so as to provide a possible solution to the concern that technologies are isolating human and nature.

In Brazil, the process of industrialization of society has been accompanied by an exponential growth of the resident population in urban centers. Therefore, the need to move people and goods within cities also increases, which can be defined as mobility in the urban context. This issue has fostered many studies that show the importance of developing actions that adequately address the issue of urban mobility, seeking to improve the quality of life in the city. Within this context, this research aims to develop an application for smartphones to provide accurate information about bus schedules for public transport in the city of Alagoinhas - BA - Brazil and consequently provide improvements in user experience. According to the data collected, MobiBus was able to alleviate the inconvenience caused by a long waiting time at the bus stop and made users feel more secure.

This paper describes the optimization project of the Easy-Learning platform, an original e-learning system, designed and developed since 2004 in the e-activities laboratory of the Applied Electronics and Information Engineering Department of the Polytechnic University in Bucharest. A variety of technologies have been used in this project: HTML5, CSS3, JavaScript, Symfony, Apache, PHP and MySQL. For the testing part a LG Optimus One Smartphone and an ipad Mini tablet have been used. The main improvements are: A - Rewriting most of the code from Views, forms and a part of the Symfony core, according to HTML5 standards; B - Radical change of the interface and its optimization for intelligent phones and tablets; C - Rewriting and optimization of the JavaScript code. In order to scale the code to mobile devices as smart phones and tablets, we have chosen to create only one application that adapts to the kind of device it is open on. The Apache server has been configured better by applying new practices for improving speed and security. Compression reduces the response periods by reducing the size of the HTTP response. The compression is made with Gzip. The used technique is called Responsive Web Design and Development that has created a web application offering an experience of optimal view, easy to read and navigate, with minimum resizing and loss of quality on a wide range of devices, from PC displays to mobile phones This technique has three basic elements: 1. Fluid gridlines; 2. Flexible images; 3. Media Queries. In order to scale a table with many columns on a mobile device, we have used Media Queries, allowing modifying the CSS depending on many conditions: ratios, widths, type of display, using the mid-width and max-width properties. A new technique for optimizing CSS and JavaScript is concatenating and minimization of all the CSS, respectively, JavaScript files in one or maximum two, in order to reduce the HTTP requests. The original contribution of the paper consists in the optimization process by using recent technologies in order to adapt the Easy-Learning platform to mobile devices and make it easier and more interactive for users and administrators.

E-learning becomes a widely used form of educational service provided with or without teacher's support as a pre-study, main course, self-study support, or refreshment. A variety of course development tools, simple and free, or sophisticated and costly, are available for course development. Together with didactic-supported methodology and guidelines for learning content development, these instruments ensure a pedagogical quality of the resulting course. If a course development tool produces a learning content according to the SCORM standard [], it enables its usage as a whole or by some components - learning objects - by a large audience, i.e. those who can access it from a SCORM-compliant learning management system. Reusability, i.e. a capacity of being applied in various contexts, is an important feature for raising efficiency of learning content production and its ROI. So far, SCORM as a technical standard ensured technical side of reusability, whereas a didactically meaningful combination of the learning object was a responsibility of a course designer. Steady growth of users going on-line from their mobile devices - phones, smartphones, tablets, e-books - pushes mobile content development. Mobile learning research matured, growing from small sessions and workshops to an individual trend, resulting in a number of big international conferences. The research in m-learning emphasizes on its innovative and informal aspects, highlighting new learning activities and scenarios, enabling creativity, interaction and collaboration [ ]. Rough summary of m-learning could be visualized as isolated islands of innovative learning experiences, together with early pilots on mobile access to the web-based learning content and studies of basic content features accessible across various mobile platforms. Although some attention has been paid to the "legacy" content and its transfer to the mobile-accessible format, this issue has been addressed solely from a technical viewpoint. Thus, the quality of the resulting mobile learning was not a subject of study, and the differences in e-learning and m-learning environments were not addressed. This study is intended to extend the understanding of the reusability concept beyond technical solutions and emphasize on the value of didactically sound content in a similar way it is done by the Learning Design []. The ultimate goal may be seen in providing some guidelines for transformation of e-learning course to its m-learning version ensuring the preservation didactical quality. The purpose of this paper is to identify differences between e-learning and m-learning environments, and explore factors that may influence the quality of the e-learning content delivered in m-learning environment using a language course as an example. Khan's e-learning framework [ ] was selected as an instrument for the learning environment analysis. The proposed framework comprises eight dimensions, along which factors influencing the quality of the e-learning environment under study are analyzed. Since its introduction, the framework has been applied to various large-scale and small-scale environments. The language learning content is represented by the ELTEC - a self-study language course [ ] which is intended for enhancement of the professional tasks-oriented language skills. The course is highly interactive though some learning activities are preceded by the explanations and illustrations. Comparison of language learning activities within e-learning and m-learning environments led to some guidelines for creation of mobile version of the ELTEC. It was concluded that due to the environment differences and specifics of the mobile devices the course should be re-organized before being transformed to the mobile version, preserving the purpose but re-defining learning objectives.

Swift changes in society, related to sciences technicians’ development, technologies, by the increase of general volume of information, pull out new requirements for maintenance, structure, and quality of education. It requires teachers to diversify a tool in the direction of the increase in possibilities of the use of mobile technologies and computer systems. Lately in the world, more attention spared to the use of mobile learning, which in obedience to «Recommendations of UNESCO on the questions of a policy in the area of mobile learning» foresees the use of mobile technology, both separate and together with other by informational computer technologies. [1]. Mobile learning allows using the open informational systems, global educational networks, unique digital resources which belong to different educational establishments and co-operate with each other. The use of existent educational resources and creation of own, based on the academic resources from informative space, allows to promote the interest of students to the study of physics, to take into account the individual features, and also features of region and framework of society of the country. During the last years in Ukraine competency-based approach to the organization of studies certainly one of basic. The new Education Act addresses the key competencies that every modern person needs for a successful life, including mathematical competence; competence in natural sciences, engineering, and technology; innovation; information and communication competence [2]. This further emphasizes the importance of providing students with quality physical education and the problems associated with it. Using mobile technology in professional teaching work, the teacher has the opportunity to implement the basic principles of the competence approach in teaching physics. An analysis of the data provided in the official reports of the Ukrainian Center for Educational Quality Assessment showed that the number of students making an external independent assessment in physics and choosing a future profession related to physics has decreased significantly. This is due to the loss of students' interest in physics and the complexity of the content of the subject, as well as the increase in the amount of information that students need to absorb. In this article, we explore the possibilities of mobile technology as a means of teaching physics students and give our own experience of using mobile technology in the process of teaching physics (for example, the optics section in primary school).

An analysis of the experience of professional training bachelors of electromechanics in Ukraine and abroad made it possible to determine that one of the leading trends in its modernization is the synergistic integration of various engineering branches (mechanical, electrical, electronic engineering and automation) in mechatronics for the purpose of design, manufacture, operation and maintenance electromechanical equipment. Teaching mechatronics provides for the meaningful integration of various disciplines of professional and practical training bachelors of electromechanics based on the concept of modeling and technological integration of various organizational forms and teaching methods based on the concept of mobility. Within this approach, the leading learning tools of bachelors of electromechanics are mobile Internet devices (MID) – a multimedia mobile devices that provide wireless access to information and communication Internet services for collecting, organizing, storing, processing, transmitting, presenting all kinds of messages and data. The authors reveals the main possibilities of using MID in learning to ensure equal access to education, personalized learning, instant feedback and evaluating learning outcomes, mobile learning, productive use of time spent in classrooms, creating mobile learning communities, support situated learning, development of continuous seamless learning, ensuring the gap between formal and informal learning, minimize educational disruption in conflict and disaster areas, assist learners with disabilities, improve the quality of the communication and the management of institution, and maximize the cost-efficiency. Bachelor of electromechanics competency in modeling of technical objects is a personal and vocational ability, which includes a system of knowledge, skills, experience in learning and research activities on modeling mechatronic systems and a positive value attitude towards it; bachelor of electromechanics should be ready and able to use methods and software/hardware modeling tools for processes analyzes, systems synthesis, evaluating their reliability and effectiveness for solving practical problems in professional field. The competency structure of the bachelor of electromechanics in the modeling of technical objects is reflected in three groups of competencies: general scientific, general professional and specialized professional. The implementation of the technique of using MID in learning bachelors of electromechanics in modeling of technical objects is the appropriate methodic of using, the component of which is partial methods for using MID in the formation of the general scientific component of the bachelor of electromechanics competency in modeling of technical objects, are disclosed by example academic disciplines “Higher mathematics”, “Computers and programming”, “Engineering mechanics”, “Electrical machines”. The leading tools of formation of the general scientific component of bachelor in electromechanics competency in modeling of technical objects are augmented reality mobile tools (to visualize the objects’ structure and modeling results), mobile computer mathematical systems (universal tools used at all stages of modeling learning), cloud based spreadsheets (as modeling tools) and text editors (to make the program description of model), mobile computer-aided design systems (to create and view the physical properties of models of technical objects) and mobile communication tools (to organize a joint activity in modeling).

The article presents and describes innovative technologies of training in the professional training of Masters. For high-quality training of students of technical specialties, it becomes necessary to rethink the purpose, results of studying and means of teaching professional disciplines in modern educational conditions. The experience of implementing the chatbot tool in teaching the discipline “Mathematical modeling of socio-economic systems” in the educational and professional program 124 System Analysis is described. The characteristics of the generalized structure of the chatbot information system for investment analysis are presented and given: input information, information processing system, output information, which creates a closed cycle (system) of direct and feedback interaction. The information processing system is represented by accounting and analytical data management blocks. The investment analysis chatbot will help masters of the specialty system analysis to manage the investment process efficiently based on making the right decisions, understanding investment analysis in the extensive structure of financial management and optimizing risks in these systems using a working mobile application. Also, the chatbot will allow you to systematically assess the disadvantages and advantages of investment projects or the direction of activity of a system analyst, while increasing interest in performing practical tasks. A set of software for developing a chatbot integrated into training is installed: Kotlin programming, a library for network interaction Retrofit, receiving and transmitting data, linking processes using the HTTP API. Based on the results of the study, it is noted that the impact of integrating a chatbot into the training of Masters ensures the development of their professional activities, which gives them the opportunity to be competent specialists and contributes to the organization of high-quality training.

Background Australia is a multi-cultural society with increasing rates of people from culturally and linguistically diverse (CALD) backgrounds. On average, CALD groups have higher rates of tobacco use, lower participation in cancer screening programs, and poorer health outcomes than the general Australian population. Lower cancer screening and smoking cessation rates are due to differing cultural norms, health-related attitudes, and beliefs, and language barriers. Interventions can help address these potential barriers and increase tobacco cessation and cancer screening rates among CALD groups. Cancer Council NSW (CCNSW) aims to reduce the impact of cancer and improve cancer outcomes for priority populations including CALD communities. In line with this objective, CCNSW commissioned this rapid review of interventions implemented in Australia and comparable countries. Review questions This review aimed to address the following specific questions: Question 1 (Q1): What smoking cessation interventions have been proven effective in reducing or preventing smoking among culturally and linguistically diverse communities? Question 2 (Q2): What screening interventions have proven effective in increasing participation in population cancer screening programs among culturally and linguistically diverse populations? This review focused on Chinese-, Vietnamese- and Arabic-speaking people as they are the largest CALD groups in Australia and have high rates of tobacco use and poor screening adherence in NSW. Summary of methods An extensive search of peer-reviewed and grey literature published between January 2013-March 2022 identified 19 eligible studies for inclusion in the Q1 review and 49 studies for the Q2 review. The National Health and Medical Research Council (NHMRC) Levels of Evidence and Joanna Briggs Institute’s (JBI) Critical Appraisal Tools were used to assess the robustness and quality of the included studies, respectively. Key findings Findings are reported by components of an intervention overall and for each CALD group. By understanding the effectiveness of individual components, results will demonstrate key building blocks of an effective intervention. Question 1: What smoking cessation interventions have been proven effective in reducing or preventing smoking among culturally and linguistically diverse communities? Thirteen of the 19 studies were Level IV (L4) evidence, four were Level III (L3), one was Level II (L2), none were L1 (highest level of evidence) and one study’s evidence level was unable to be determined. The quality of included studies varied. Fifteen tobacco cessation intervention components were included, with most interventions involving at least three components (range 2-6). Written information (14 studies), and education sessions (10 studies) were the most common components included in an intervention. Eight of the 15 intervention components explored had promising evidence for use with Chinese-speaking participants (written information, education sessions, visual information, counselling, involving a family member or friend, nicotine replacement therapy, branded merchandise, and mobile messaging). Another two components (media campaign and telephone follow-up) had evidence aggregated across CALD groups (i.e., results for Chinese-speaking participants were combined with other CALD group(s)). No intervention component was deemed of sufficient evidence for use with Vietnamese-speaking participants and four intervention components had aggregated evidence (written information, education sessions, counselling, nicotine replacement therapy). Counselling was the only intervention component to have promising evidence for use with Arabic-speaking participants and one had mixed evidence (written information). Question 2: What screening interventions have proven effective in increasing participation in population cancer screening programs among culturally and linguistically diverse populations? Two of the 49 studies were Level I (L1) evidence, 13 L2, seven L3, 25 L4 and two studies’ level of evidence was unable to be determined. Eighteen intervention components were assessed with most interventions involving 3-4 components (range 1-6). Education sessions (32 studies), written information (23 studies) and patient navigation (10 studies) were the most common components. Seven of the 18 cancer screening intervention components had promising evidence to support their use with Vietnamese-speaking participants (education sessions, written information, patient navigation, visual information, peer/community health worker, counselling, and peer experience). The component, opportunity to be screened (e.g. mailed or handed a bowel screening test), had aggregated evidence regarding its use with Vietnamese-speaking participants. Seven intervention components (education session, written information, visual information, peer/community health worker, opportunity to be screened, counselling, and branded merchandise) also had promising evidence to support their use with Chinese-speaking participants whilst two components had mixed (patient navigation) or aggregated (media campaign) evidence. One intervention component for use with Arabic-speaking participants had promising evidence to support its use (opportunity to be screened) and eight intervention components had mixed or aggregated support (education sessions, written information, patient navigation, visual information, peer/community health worker, peer experience, media campaign, and anatomical models). Gaps in the evidence There were four noteworthy gaps in the evidence: 1. No systematic review was captured for Q1, and only two studies were randomised controlled trials. Much of the evidence is therefore based on lower level study designs, with risk of bias. 2. Many studies provided inadequate detail regarding their intervention design which impacts both the quality appraisal and how mixed finding results can be interpreted. 3. Several intervention components were found to have supportive evidence available only at the aggregate level. Further research is warranted to determine the interventions effectiveness with the individual CALD participant group only. 4. The evidence regarding the effectiveness of certain intervention components were either unknown (no studies) or insufficient (only one study) across CALD groups. This was the predominately the case for Arabic-speaking participants for both Q1 and Q2, and for Vietnamese-speaking participants for Q1. Further research is therefore warranted. Applicability Most of the intervention components included in this review are applicable for use in the Australian context, and NSW specifically. However, intervention components assessed as having insufficient, mixed, or no evidence require further research. Cancer screening and tobacco cessation interventions targeting Chinese-speaking participants were more common and therefore showed more evidence of effectiveness for the intervention components explored. There was support for cancer screening intervention components targeting Vietnamese-speaking participants but not for tobacco cessation interventions. There were few interventions implemented for Arabic-speaking participants that addressed tobacco cessation and screening adherence. Much of the evidence for Vietnamese and Arabic-speaking participants was further limited by studies co-recruiting multiple CALD groups and reporting aggregate results. Conclusion There is sound evidence for use of a range of intervention components to address tobacco cessation and cancer screening adherence among Chinese-speaking populations, and cancer screening adherence among Vietnamese-speaking populations. Evidence is lacking regarding the effectiveness of tobacco cessation interventions with Vietnamese- and Arabic-speaking participants, and cancer screening interventions for Arabic-speaking participants. More research is required to determine whether components considered effective for use in one CALD group are applicable to other CALD populations.
