Historiografia pedagogiczna w czasopismach tradycyjnych i elektronicznych

Scientific and research periodicals play an extremely important part in popularizing (and promoting) results of research studies, though this role is not equally appreciated across different domains of science. This becomes apparent if we compare the number of traditional and electronic titles of periodicals in such disciplines as medicine, natural science and exact science on the one side, and those that represent the humanities, broadly understood, on the other. The advantage of electronic content in the former group is overwhelming. Nowadays, we use two terms in relation to periodicals available online and launched on the electronic platform. The terms make a distinction between a degree of their involvement in the cyber space. “Digitalization” means a certain transitory state between traditional periodicals in print and virtual publications; in other words, a product of “digitization” is an electronic copy (e.g. a scanned text) of a text originally published in print, whereas the notion of “digital authorship (the author as digital producer), in Polish: cyfryzacja” deals with an entirely electronic publication with specific properties underlined by multimedia and hypertext capabilities. Digital research information as an entirely new quality has not been yet appropriately appreciated. The history of education as a discipline of research does not have its own electronic platform that would offer peer-reviewed research papers in Open Access (OA), e-books or electronic document repositories. For the time being, the most recent Polish periodical within this discipline, i.e. Biuletyn Historii Wychowania, has only a front page, ToCs and a masthead available online, without access to full-text electronic content.

ОСНОВНІ ПРОБЛЕМИ ТА ШЛЯХИ ВПРОВАДЖЕННЯ МУЛЬТИМЕДІЙНИХ ТЕХНОЛОГІЙ В ПОЧАТКОВІЙ ШКОЛІ

In this article it is assumed that the decisive kind of application of multimedia learning tools is their integration into the learning process in the form of interesting, dynamic, and game forms. Elementary students learn innovation and at the same time deepen their knowledge of certain subjects by means of computers. The author admits that the introduction of multimedia technologies into the educational process is an attribute of the harmonious integration of various types of information. Knowledge of the future teacher of elementary school about various types of multimedia technologies allows pedagogically grounded use of powerful didactic capabilities of multimedia in the primary education.Each time after the appearance of a new technical device, teachers are contemplating how to apply it to the solution of didactic tasks. So, by examining the natural features of learning resources, teachers formulate their didactic qualities and functions in the learning process.The students study the surrounding world with the help of all sense organs. Still, the key sources of information acquisition are visual analyzers. It is no coincidence that 90% of all information students receive with the assistance of the view, and 10% – with the help of hearing. “It’s better to see once than to hear 100 times” – so it’s a true proverb.In recent years, copying and video equipment, musical centers, a new generation of diagonal projectors and graphic projectors have been developing and expanding intensively in schools. The number of modern computer rooms in schools is increasing. Effective use of information technology in the educational process helps to successfully address the challenges faced by the school and the teacher.

How to use and knowledge management capabilities in today’s highly competitive environment to help organizations respond quickly to market changes and customer needs is a major challenge in the organization of information technology, and one of the most important research issues in the field of information systems. Modern enterprises have shown great enthusiasm in using complex information technology to gain competitive advantage. The successful application of enterprise information technology requires enterprises to deeply understand the absorption process of information technology within the organization. The introduction of information technology in the organization often means the transfer of technical knowledge, management knowledge and institutional knowledge contained in the software system. Multimedia knowledge management has become a key factor affecting the in-depth application of enterprise information systems. Therefore, this paper starts from the level of multimedia knowledge management, and explores the impact of organizational knowledge and information technology-related knowledge base and absorptive capacity on enterprise system information absorption. At the same time, it also discusses the impact of multimedia information resources on organizational information absorption, focusing on the mediating role of multimedia information management capabilities and the regulatory role of MULTIMEDIA KNOWLEDGE MANAGEMENTs information support, confirming that information resources will improve organizational information absorption. When organizations need to improve the absorption of their organizational information, resorting to information is often an effective way to enrich the research on organizational information absorption from the perspective of multimedia knowledge management and information resources.

A Smartphone Application for Automated Decision Support in Cognitive Task Based Evaluation of Central Nervous System Motor Disorders

New technology enables constant boost to the powers of mobile devices, which in the previous years have transformed from simple mobile phones to smart phones. Computational powers of these electronics enable actions that previously were possible only for computers. By the use of special applications, we may benefit from sensors and multimedia capabilities of operating systems. Therefore, a new era for devoted implementations opens, in which a smart application can take a role of computing system to estimate the symptoms of diseases by evaluating signals coming from a human body. We propose a model of an application implemented for mobile android systems, which can be used for examination of central nervous system motor disorders occurring in patients suffering from Huntington (HD), Alzheimer, or Parkinson diseases. In particular, the model tracks tremors (involuntary movements), and cognitive (memory loss or dementia) impairments using touch and visual stimulus modalities. The proposed model interprets the symptoms from human bodies that indicate one of the diseases of the nervous system. Pre-processing of collected data for feature extraction is executed on a mobile device by using core functionality and methods provided in android's application programming interface. The information is evaluated by a back-propagation neural network classifier and the result is presented to the end user. The system is able to contact medical supervision and provide an assistance from the clinic. The system uses a collected dataset of 1928 records, taken from 11 HD patients and 11 healthy persons in Lithuania, to gather statistics about examinations and presents the results as medical evaluation with prediction on the state of health. The accuracy of recognition of early, prodromal symptoms for central nervous system motor disorders is 86.4% (F-measure 0.859). The app (available on Google Play) is easy to use and is efficient tool for decision support in medical examinations. The use of intelligent apps which can help to evaluate neurodegenerative disorders is an important enhancement to medical diagnosis. The developed smartphone app supports the doctor with additional results that are easy to compare with other examinations. This kind of examination is a nice change from classic stereotypes, especially for younger age patients, who are used to various aspects of information technology.

Interactive multimedia library products: forming skills of technology while preparing bachelors of library and information activities

Currently, the range of information products and services provided remotely is developing and expanding. Modern library users often prefer remote services to traditional forms. The real communication is inferior to virtual one, the popularity of electronic information products is growing. Libraries transform popular traditional products and services into electronic formats. So traditional quizzes, which are popular in libraries, are moving into a new form, become a dynamically developing electronic product. The popularity and demand of multimedia products for modern users led to emerging a wide range of such products in the library practice. Multimedia capabilities combine different forms of information and provide visibility, visual appeal and increase interest among users. The most original of them are the products with interactive features that provide the opportunity to dialogue with users and implement active actions. The most popular are such interactive multimedia products as an electronic interactive exhibition, a multimedia interactive quiz, a video with interactive elements. Libraries can also develop such products without extensive software, hardware and human resources. To ensure the quality of the created interactive multimedia products, it is necessary to study the technology of their preparation. Based on the interactive multimedia works created by students the author considers their features, cases of interactive opportunities realization; characterizes the experience to form of skills of technology of their preparation at bachelors of library and information activity. Actively developing of remote library services using information-communicating technologies, transforming traditional forms into multimedia format contributes to the development of interactive multimedia forms, as well as allows attracting users and increase the demand for documents. Game forms of work with readers are especially relevant for children and youth audience. Development and implementtation of multimedia interactive product is economically less labor-intensive process than the traditional library event.

A Student-Generated Video Careers Project

This article describes how in recent years, the multimedia recording capabilities of mobile devices have been used increasingly to create a more active, learner-centred educational experience. Despite the proven value of student-generated multimedia projects, there are still gaps in our understanding of how students learn during them. This article reports on a project in which first-year information technology students interviewed IT professionals in their workplace and video-recorded the interview to enable sharing with their peers. In order to understand the statistically significant increases found in students' learning, student diaries and reflections were analyzed qualitatively. Factors found to contribute to learning included: the iterative nature of student activities; the multiple, evolving representations of knowledge as students proceeded through the project; the importance of the workplace context in engaging students and enhancing learning; the affordance of mobile technology for capturing and sharing this context; and the collaborative and metacognitive processes fostered by the project.

Dual-structural edge networking paradigm: an analysis study in terms of multimedia content delivery

To eliminate the phenomenon of the digital divide in the area lacking Internet infrastructure support and accomplish the vision of “The Internet is for everyone” envisaged by Vint Cerf, our group pioneered a dual-structural edge networking paradigm, being utilized to construct a DSN (dual-structural network) for multimedia content delivery. The aim of this paper is to study multimedia content delivery capability for the edge networking paradigm. First of all, for further understanding the delivery capability, we formalize DSN in terms of network architecture and logical entity interaction and propose a hierarchical model and triple B model sequentially. Then, we propose a multi-dimension analysis methodology of multimedia content delivery for networking paradigm from a high-level perspective, in which network performance and user evaluation are taken into account. Further, according to the methodology, we design a specific comparative analysis model of multimedia content delivery capability for DSN, consisting of sub-model based on transmission performance and sub-model based on user utility. Lastly, we conduct direct and indirect comparative analysis studies by utilizing the model, and numerical results shed light on that DSN outperforms TCP/IP, NDN (named data networking) and BSN (broadcast-storage network) in terms of the delivery capability. Given this, we conclude that DSN is a more promising paradigm for multimedia content delivery.

Slack-Time Closed-Loop Control System for Multimedia Mobile Devices

Nowadays there is a pervasive utilization of consumer-electronics mobile devices with powerful multimedia capabilities. The suitable management of their power consumption is critical in order to meet the user expectations in terms of battery lifetime. But the reduction of the dynamic-power component of the consumption may sometimes impair the quality of multimedia experience (QoE), which is not always acceptable. This paper proposes a closed-loop control system that can monitor the QoE in the form of the slack time of video decoding tasks and act on the CPU frequency to regulate it. Some results are presented in comparison with dynamic Linux governors which show a suitable behavior in guaranteeing enough QoE, even with power savings of almost 5% and low overhead. This enables its use as an assistant part of dynamic-power savers.

Testimonials and Informational Videos on Branded Prescription Drug Websites: Experimental Study to Assess Influence on Consumer Knowledge and Perceptions.

BackgroundDirect-to-consumer (DTC) promotion of prescription drugs can affect consumer behaviors and health outcomes, and Internet drug promotion is growing rapidly. Branded drug websites often capitalize on the multimedia capabilities of the Internet by using videos to emphasize drug benefits and characteristics. However, it is unknown how such videos affect consumer processing of drug information.ObjectiveThis study aimed to examine how videos on prescription drug websites, and the inclusion of risk information in those videos, influence consumer knowledge and perceptions.MethodsWe conducted an experimental study in which online panel participants with acid reflux (n=1070) or high blood pressure (n=1055) were randomly assigned to view 1 of the 10 fictitious prescription drug websites and complete a short questionnaire. On each website, we manipulated the type of video (patient testimonial, mechanism of action animation, or none) and whether the video mentioned drug risks.ResultsParticipants who viewed any video were less likely to recognize drug risks presented only in the website text (P≤.01). Including risk information in videos increased participants’ recognition of the risks presented in the videos (P≤.01). However, in some cases, including risk information in videos decreased participants’ recognition of the risks not presented in the videos (ie, risks presented in text only; P≤.04). Participants who viewed a video without drug risk information thought that the website placed more emphasis on benefits, compared with participants who viewed the video with drug risk information (P≤.01). Compared with participants who viewed a video without drug risk information, participants who viewed a video with drug risk information thought that the drug was less effective in the high blood pressure sample (P=.03) and thought that risks were more serious in the acid reflux sample (P=.01). There were no significant differences between risk and nonrisk video conditions on other perception measures (P>.05). In addition, we noted a few differences among the types of videos.ConclusionsIncluding risks in branded drug website videos may increase in-video risk retention at the expense of text-only risk retention.

Robotic Arm-Based Face Recognition Software Test Automation

Facial recognition is a feature that uses facial detection algorithms to detect a face and then invokes facial recognition algorithms to try to match the person’s face. First, a person’s face needs to be enrolled; during enrollment, the person’s facial details are saved in a database—in this case, a mobile phone. The facial recognition algorithm uses this database to match the currently presented face with the faces saved in the database. The efficiency of a facial recognition algorithm depends upon the speed at which it can detect and recognize faces. The problem we address in this paper is that a reliable, automated method for testing facial recognition features in mobile phones. Because the multimedia capabilities of smartphones have expanded phenomenally, the need for thoroughly testing facial recognition algorithms has become crucial. The uses of facial recognition can range from facial authentication for unlocking phones to security for a number of other applications. To meet these needs, a reliable, automated test for validating the facial recognition algorithms must be developed. The challenge for the software test team was to automate the test cases, which involve tilting the phone at specific angles from the test subject. The permissible angular movements of the phone are determined by the algorithmic specifications of the facial recognition algorithm. We tested scenarios involving multiple faces, motion blur, panning the phone in front of the test subject faces at various speeds, and so on. We adopted a robotic arm to perform the facial recognition test cases and developed software to program the robotic arm to test the phone’s facial recognition software for functionality, performance, and stability as well as adversarial tests. This paper discusses the computer vision use case for facial recognition and describes how we developed an automated facial recognition test suite using a robotic arm.

Smart Refrigerator with Recipe Assistance

Internet of Things (IoT) will lead to a technological revolution that will change the way people live and interact with their surroundings. Intelligent appliances combined with multimedia capability have been emerging in everyone's life. Smart home is one of the prominent areas of intelligent advances. Kitchen is considered as the center of our house, where the refrigerator plays an important role. Smart Refrigerator with Recipe Assistance will help in automating the refrigerator. The authors propose a system that would track the stock of ingredients in the refrigerator with the help of RFID tags and load cells. According to the availability of ingredients a list of possible recipes is predicted and suggestions will be given to the user. Whenever an item is identified by a RFID tag, estimations on the usage of ingredients are made and we can get notifications about the scarce products. The system will also help in checking the availability of ingredients based on the recipe user wishes to cook. The time required by an individual for manually checking the availability of ingredients in the refrigerator and then thinking about what to cook is greatly reduced using this system. Most of the information is automatically generated using RFID tags. Once the user logins into the application he/ she will be suggested the possible list of recipes based on the availability. Human intellectual power then can be used for new creative processes rather than using it for routine chores.
