The process of creating computer-based music is increasingly being conceived in terms of complex chains of mediations involving composer/performer and computer software interactions that prompt us to reconsider notions of materiality within the context of digital cultures. Recent scholarship has offered particularly useful re-evaluations of computer music software in relation to musical instrumentality. In this article, we contend that given the ubiquitous presence of computer units within contemporary musical practices, it is not simply music software that needs to be reframed as musical instruments, but rather the diverse material strata of machines identified as computers that need to be thought of as instruments within music environments. Specifically, we argue that computers, regardless of their technical specifications, are not only ‘black boxes’ or ‘meta-tools’ that serve to control music software, but are also material objects that are increasingly being used in a wide range of musical and sound art practices according to an ‘analog’ rather than ‘digital’ logic. Through a series of examples implicating both soft and hard dimensions of what constitutes computers, we provide a preliminary survey of practices calling for the need to rethink the conceptual divide between analog and digital forms of creativity and aesthetics.

Introduction: Given the increasing use of electronic devices, and the increasing number of complaints with its use, we intend to evaluate the prevalence of manifestations of dry eye and ocular fatigue in a population of individuals, who use the computer daily to perform all their professional tasks, as well as to correlate these complaints with the number of hours of digital use as well as their possible improvement with behavioural measures and use of tear drops.Material and Methods: A total of 77 individuals (154 eyes) were evaluated on two separate days with a 1-month interval. They completed two questionnaires: OSDI and PEG Eye Fatigue. An objective ocular surface assessment was performed: Schirmer test without anesthetic, DR-1a Dry Eye Monitor™, hyperemia evaluation, lacrimal break up, presence of keratitis and lesions in the conjunctiva, as well as near accommodation point and near convergence point. After the first evaluation, the subjects were divided into two groups: group A (< 2 hours of computer working) and group B (> 2 hours of computer working). Some environmental measures to reduce complaints and recommendation of use of artificial tears were explained to the latter.Results: There was a statistically significant difference in the majority of the parameters evaluated in the group B, in relation to the morning period (group A) - tear film (p = 0.032), hyperemia (p < 0.001), BUT (p < 0.001), keratitis (p < 0.001), conjunctival lesion (p = 0.002) and accommodation point (p < 0.001). In the evaluation – one month later - there were no statistically significant differences in any of the parameters analysed in the group A, and in group B there was a decrease in most parameters at the end of that period - Schirmer test (p = 0.005), lacrimal film (p = 0.022), keratitis (p < 0.001), conjunctival lesion (p = 0.005) and fatigue score (p < 0.001).Discussion: It was thus possible to show the appearance of ocular fatigue and ocular surface changes with prolonged use of computers (> 2 hours) as well as a significant improvement in symptomatology (subjective assessment) as well as of ocular surface changes (objective evaluation) with the implementation of postural measures, regular breaks and use of lubricants. This is the first study, to the best of our knowledge, of digital asthenopia in which, in addition to the subjective evaluation, the presence of ocular surface modifications (objective assessment) were evaluated and the respective improvement with the aforementioned ergophthalmological measures were evaluated.Conclusion: This survey highlights the increased overall level of awareness that we need to have to face the rapid and wide-scale changes driven by the emergence of digital technology and, more particularly, its impact on user’s vision and posture. We concluded that the longer we use the electronic devices (more than two hours) the more severe the complaints and rates of ocular surface changes are. Environmental and ocular strategies can attenuate or even eliminate the discomfort caused by this syndrome, and increase professional performance and quality of life.

Computers and photography has had a long and complicated relationship throughout the years. As image processing and manipulating capabilities advanced on the computer front, photography re-birthed itself with digital cameras and digital imaging techniques. Development of interconnected social sharing networks like Instagram and Twitter feeds the photographers’/users’ thirst to show off their momentaneous “been there/seen that – capture the moment/share the moment” instincts. One other unlikely front emerged as an image processing power of the consumer electronics improved is “video game worlds” in which telematic travellers may shoot photographs in constructed fantasy worlds as if travelling in real life. While life-like graphics manufactured by the computers raise questions about authenticity and truthfulness of the image, the possible future of the photography as socially efficient visual knowledge is in constant flux. This article aims to reflect on today’s trends in in-game photography and tries to foresee how this emerging genre and its constructed realities will transpose the old with the new photographic data in the post-truth condition fostering for re-evaluation of photography truth-value.

The development of information technology, along with its indisputable advantages, has brought to our lives a number of negative phenomena related to the illegal use of computers and telecommunications. However, the issue of using digital information as evidence in the criminal procedural legislation of Ukraine remains almost unsettled, in particular, the place of digital evidence in the system of procedural sources of evidence (digital evidence is difficult to unambiguously attribute to material evidence or documents) remains unclear. Criminal proceedings raise problems regarding the correct assessment of digital (electronic) evidence for their identity and admissibility, which certainly does not contribute to the effective use of digital technologies and sources of information in national proceedings. The purpose of the article is to research the problematic issues of determining the appropriateness and admissibility of digital (electronic) evidence during criminal proceedings, as well as to identify and disclose individual principles for their proper procedural evaluation. The research deals with the current state of theoretical studies of the issue of the appropriateness and admissibility of digital evidence both in Ukrainian criminal procedure science and abroad. The peculiarities of the requirements for the assessment of traditional evidence and digital evidence in criminal proceedings are analyzed. The author identifies the features of obtaining (collecting) digital evidence, given their intangible nature, with a view to their further positive evaluation by admissibility and appropriateness criteria. Taking into account the international experience, the author concludes that there is a need to distinguish separate principles of admissibility and availability for digital evidence, revealing their content. The urgent need to settle this issue, both at the legislative level and through appropriate judicial clarification, is substantiated. It is emphasized that in view of the specific nature of digital (electronic) evidence to ensure their authenticity and reliability in criminal proceedings is associated with the promptness of investigative actions, mandatory involvement of an expert, professional training of all subjects of evidence and steady adherence to recommendations for working with digital evidence.

Аннотация. В статье констатируется тот факт, что категория «Информация» является одной из самых дискуссионных в истории науки и философии. В XX веке появился новый вид информации — компьютерная (электронная, цифровая, машинная и т. д.). Применительно к объекту электронной цифровой криминалистики рассматриваются вопросы точного определения понятия информации, циркулирующей в компьютерных системах, сетях и иных электронных устройствах. Объектом электронной цифровой криминалистики являются как раз общественные отношения, связанные с собиранием, исследованием и использованием электронной цифровой информации и информационно-технологических устройств. Предметом электронной цифровой криминалистики полагаем закономерности возникновения, движения, трансформации криминалистически значимой электронной информации, закономерности оценки и использования криминалистически значимой электронной цифровой информации.В статье анализируются различные мнения относительно правильного наименования данной информации, определяются их положительные и отрицательные стороны. По результатам анализа различных подходов к рассматриваемой информации констатируется, что оптимальным для целей практической правоохранительной деятельности является определение «электронная цифровая информация», как отражающая и способ записи и своеобразный «язык» записи. Характеристика «электронный» говорит в первую очередь о способе записи, изменения, чтения и удаления с помощью движения электронов, электро-магнитных взаимодействий. Характеристика «цифровой» — о языке записи путем дискретизации аналоговой информации и представления ее в виде, как правило, дуальной последовательности цифр.При этом для раскрытия сущности данного вида информации необходимо указание на способ записи информации, форму записи, ее размещение и функциональное предназначение.По результатам исследования делается вывод о том, что электронную цифровую информацию можно определить как информацию, зафиксированную любым способом, но трансформируемую в человекочитаемый вид с помощью электромагнитных взаимодействий и кодированную с использованием цифрового кода, пригодную для автоматической обработки, находящуюся в информационно-технологических устройствах и передаваемую между ними любым способом либо распределенную между ними.Безусловно, активная разработка вопросов, связанных с электронной цифровой информацией в криминалистике, будет способствовать расширению информации о преступлении, переводимой из потенциальной криминалистически значимой в актуальную. Abstract. The article states that the category "Information" is one of the most controversial in the history of science and philosophy. In the 20th century, a new type of information appeared — computer (electronic, digital, machine, etc.). In relation to the object of electronic digital forensics, the issues of precise definition of the concept of information circulating in computer systems, networks and other electronic devices are considered. The object of electronic digital criminalistics is precisely social relations related to the collection, research and use of electronic digital information and information technology devices. The subject of electronic digital forensics, we consider the patterns of occurrence, movement, transformation of criminally significant electronic information, patterns of evaluation and use of criminally significant electronic digital information.The article analyzes various opinions regarding the correct naming of this information, identifies their positive and negative sides. According to the results of the analysis of various approaches to the information under consideration, it is stated that the optimal definition for the purposes of practical law enforcement is the definition of “electronic digital information” as reflecting both the method of recording and a kind of “language” of recording. The characteristic “electronic” speaks primarily about the method of writing, changing, reading and deleting using the movement of electrons, electro-magnetic interactions. The characteristic of “digital” is about the language of recording by sampling analog information and presenting it in the form, as a rule, of a dual sequence of digits.At the same time, in order to disclose the essence of this type of information, it is necessary to indicate the method of recording information, the form of recording, its placement and functional purpose.According to the results of the study, it is concluded that electronic digital information can be defined as information recorded in any way, but transformed into a human-readable form using electromagnetic interactions and encoded using a digital code, suitable for automatic processing, located in information technology devices and transmitted between them in any way, or distributed between them.Of course, the active development of issues related to electronic digital information in criminology will contribute to the expansion of information about the crime, translated from potential criminally significant to relevant.

Abstract: The internet is expanding at a breakneck pace, as the number of crimes perpetrated using or against computers. The area of computer forensics has arisen in reaction to the rise of computer crime. Computer forensics is the meticulous collection and examination of electronic evidence that not only analyses the damage to a computer because of an electronic attack but also recovers lost data from such a system to convict a criminal. As a result, the standard forensic process that is required after an electronic attack involves collecting evidence from a computer system, analyzing, and presentation of the collected evidence in court. Forensics deals primarily with the recovery and analysis of latent evidence. The growth of digital forensics has substantially increased the requirement for effective tools. There are several tools available today which are used to investigate the OS of a given computer. The purpose of this paper is to compare OS forensics tools by evaluating their ease of use, functionality, performance, and product support and documentation. This research will provide a brief comparative analysis of two widely used OS forensic tools-OSForensics and autopsy based on various contradictory factors.

In this paper, we describe techniques for predictive modeling of human-computer interaction (HCI) and discuss how they could be used in the development and evaluation of user interfaces for digital health systems such as electronic health record systems. Predictive HCI modeling has the potential to improve the generalizability of usability evaluations of digital health interventions beyond specific contexts, especially when integrated with models of distributed cognition and higher-level sociotechnical frameworks. Evidence generated from building and testing HCI models of the user interface (UI) components for different types of digital health interventions could be valuable for informing evidence-based UI design guidelines to support the development of safer and more effective UIs for digital health interventions.

As a new form of e-commerce, digital industry will become a tool to enhance regional competitiveness and win the allocation of resources, and its advanced degree is the standard to measure economic strength. In the process of development, countries and regions need to master their development status, so a set of digital industry evaluation index system is necessary to help various fields monitor the development status of e-commerce industry, aiming at providing more targeted services. Therefore, the establishment of regional digital industry progress index is conducive to evaluating and improving the development level of e-commerce. Because of the unbalanced development among different regions and the diversity and fuzziness of evaluation indexes, how to evaluate the development degree of cross-border electronic commerce in a region has become the main problem at present. In this paper, the evaluation index of regional promotion degree in cross-border electronic commerce is constructed, and on this basis, the intuitionistic fuzzy multiattribute group decision-making method based on induction is used to evaluate the promotion degree of regional cross-border electronic commerce. By analyzing the actual situation of cross-border Internet e-commerce comprehensive evaluation cases in various regions of Zhejiang Province, it is proved that this method is really effective. In view of this, this paper constructs an integrated multiangle monitoring index system of regional digital industry progress index, puts forward a subjective and objective method based on the principle of the minimum distance between the evaluated object and the ideal point, and combines the regional digital industry progress index with the comprehensive index method. The measurement model is used to measure the progress of digital industry in this region from June 2019 to June 2020, as an empirical object. The empirical results will show that this road is easy, and at the same time, we can fully grasp the progress of digital technology in a region.

Based on the analysis of the curricula in computer science subjects in the countries with traditions in the field and the experience of the Republic of Moldova, it is argued the need to further promote the curricular reform in general education. It is proposed to re-conceptualize the current and summative assessment methods in computer science disciplines by basing them on the evaluation of digital products developed by students: documents and electronic presentations, Web documents, computer programs, simulation models. It is recommended that the assessment itself be conducted in a digital environment, giving students the opportunity to demonstrate their knowledge and skills directly on the computer.

ABSTRACT A prototype system was designed and assembled to electronically support all the steps involved in the cleanup phase of an oil spill response, from field data acquisition to decision making at a command post. The system included satellite communication, wireless Local Area Networks (LANs), Geographical Information Systems (GIS), and computerized Shoreline Cleanup Assessment Team (SCAT) support software. Field data entry was done using a penpad linked to a wearable computer, including (1) creation of electronic shoreline oiling summary diagrams with the help of a GIS; (2) completion of electronic SCAT forms; (3) exact positioning of oil patches and other spatial information with a differential Global Positioning System (DGPS); and (4) recording of images with a video camera. Information from the field was transmitted through a wireless LAN to a portable computer, which relayed the data via satellite communication to a central facility where information was integrated and analyzed for decision making. The system was evaluated during a number of field trials with personnel from the Bureau of Emergencies Response (state of Florida), normally involved in oil spill response. The evaluation demonstrated that (1) a stand-alone system, including differential GPS capability, was optimal to support SCAT activities in the field; (2) the setup and operation of a wireless LAN was both cumbersome and not worth the improvement in peiformance (reduced transfer time), particularly due to the necessity of deploying unwieldy directional antennas; (3) a major limitation was that the wearable computer's display was not visible under bright sunlight; (4) communication by wireless LAN and satellite network proved feasible, but too difficult to do routinely; (5) the use of computerized software tools in combination with detailed base maps (digital orthoquads) proved to be a huge improvement over the use of pen and paper; (6) the use of an all-electronic environment substantially shortened the length of time necessary to produce decision maps.

The training of students - future teachers in Informatics and Informational Technologies is a responsible and multi-layered task. It requires future teachers to use the modern digital technologies providing the digital competence required by national and European standards; to know the current and perspective features of modern young people; to be skillful at software tools for creating electronic learning objects so that they can create effective blended learning in accordance with the generally accepted ergonomic and didactic aspects of pedagogical psychology; to apply digital training methodologies for training in computer science subjects; to define, research and find solution to scientific problems in their pedagogical practice.Changes in the characteristics of modern pupils that characterize them as a ‘Digital Generation’ genuinely generate the need for interactive e-learning, mobile and blended learning, especially in the field of computer sciences. Considering these facts parallel changes in the taxonomy of learning objectives have also emerged - from classic to revised to digital.To explore the problem of synchronizing the training of future teachers in Informatics and Informational Technologies in line with the dynamics of the learning objectives taxonomy, we use the following methods: we clarify the concepts of ‘blended learning’, ‘e-learning’, ‘m-learning’ and ‘electronic learning object’; we review the characteristics of the digital generation; we follow the evolution in the taxonomy of learning objectives; we clarify the levels of interactivity that are achieved when creating e-learning objects for blended learning implementation; we offer digital instrumentation and authoring tools that students acquire to create electronic learning objects for the high cognitive levels of Bloom's digital taxonomy - evaluation and creation.In conclusion, we comment on the advantages of being skillful at the toolkit for creating electronic learning objects of varying degrees of interactivity and suitable models for their inclusion in the Informatics and Information Technology teaching units in the implementation of blended learning.

This research introduces the development of an electronic flowmeter based on the drag force that a body experiences when immersed in a fluid stream. Its main goal was the development of an Electronic Drag Force Flowmeter (EDFF) using a load cell, as well as the evaluation of its performance parameters. The developed flowmeter should not require specialized labor, equipments, computers or any sophisticated and complex method, providing an easy and accurate way of flow estimation. This research was carried out in the following stages: (i) EDFF mechanical structure development; (ii) data acquisition system and embedded software design; and (iii) evaluation of EDFF performance parameters. EDFF has routines for instantaneous flow rate measurement, interactive calibration, and also several flow meter parameter adjustments, allowing data transmission via a RS232 protocol. The real-time flow measurement task updates values of instantaneous flow rate each seven seconds, enabling unit selection. The interactive calibration routine guides users during all calibration process showing instructions on EDFF's display. A data digital filtering procedure was implemented in an embedded software using the Grubbs' Test in order to identify and to remove outliers from the acquired data. The Method of Least Squares was also implemented in the embedded software in order to calculate the fitting model coefficients on the calibration procedure. This flowmeter is able to work from 1.94 to 7.78 dm³ s-1 with an uncertainty of ± 5.7%. The coefficient of local head loss (K) was close to 0.55 for Reynolds number values higher than 10(5). The developed EDFF is a low-cost and stand-alone system with potential for agricultural applications.

This paper reports the modeling and performance enhancement of complementary metal-oxide-semiconductor (CMOS) inverters using parallel-gated junctionless field-effect transistors (PGJLFET). A mathematical model for different parameters, namely, low and high input voltage, low and high output voltage, noise margin, rise time, fall time, propagation delay, and power dissipation of the inverter circuit was established. To establish the model for various parameters, potential models at the source-channel boundary and the potential at the drain-channel boundary are considered. The variations in the voltage transfer characteristics of the output current with respect to the input voltage and the power dissipation with respect to the input voltage for steady-state conditions and transient states were investigated for different gate dielectrics, gap lengths, and gate oxide thicknesses. The models were validated by comparing them with technology computer-aided design (TCAD) simulation results. The noise margin, rise time, fall time, and propagation delay of the PGJLFET-based inverter are estimated and compared with those of a conventional junctionless transistor. It has been observed that the PGJLFET exhibits an improvement in the noise margin and propagation delay compared with conventional junctionless transistors.

This paper describes an online collaborative model designed to allow meaningful, authentic interactions between college English as a Foreign Language (EFL) students and adult native speakers of English. The program uses technology to bridge the gap between the need of EFL students to interact with native speakers for successful language learning and the geographical distance of EFL classrooms. The two groups of participants were brought together in a symbiotic relationship enabled and shaped by an online collaborative learning environment. This study employed two 4-member teams collaborating on an electronic bulletin board to address problems such as lack of response and lack of purpose that current models of online exchange face. Findings indicate that the team model is a viable alternative to one-to-one or many-to-many correspondence. They also suggest that collaborative activities may play an important role in fostering meaningful and lasting interactions.

A foggy environment may cause digitally captured images to appear blurry, dim, or low in contrast. This will impact computer vision systems that rely on image information. With the need for real-time image information, such as a plate number recognition system, a simple yet effective image enhancement algorithm using a hardware implementation is very much needed to fulfil the need. To improve images that suffer from low exposure and hazy, the hardware implementations are usually based on complex algorithms. Hence, the aim of this paper is to propose a less complex enhancement algorithm for hardware implementation that is able to improve the quality of such images. The proposed method simply combines brightness and contrast manipulation to enhance the image. In order to see the performance of the proposed method, a total of 100 vehicle registration number images were collected, enhanced, and evaluated. The evaluation results were compared to two other enhancement methods quantitatively and qualitatively. Quantitative evaluation is done by evaluating the output image using peak signal-to-noise ratio and mean-square error evaluation metrics, while a survey is done to evaluate the output image qualitatively. Based on the quantitative evaluation results, our proposed method outperforms the other two enhancement methods.

Objectives. This systematic review aimed at assessing the therapeutic efficacy of computer-assisted or digitally constructed occlusal splints in comparison to conventional splint treatment for temporomandibular disorders or bruxism. Material and methods. The study was prospectively registered in the Open Science Framework. Four electronic databases, PubMed, Embase, Web of Science, and Scopus, were searched comprehensively. The following keywords were employed: “3D-printed”, “additive manufacture”, “computer-aided design/computer-aided manufacturing”, “temporomandibular joint”, “temporomandibular joint dysfunction”, “bruxism”, “disc displacement”, “temporo-mandibular disorder”, “splint’, “oral splint”, “occlusal splint”, “occlusal device”, “bite splint”, “occlusal appliance”. Two risk of bias evaluation instruments were used to assess the quality of the included studies. Outcomes. Following the application of the search strategy, a total of 557 publications were identified in the electronic databases. Seven eligible articles were finally included in the analysis. Six publications (85.7%) compared digitally manufactured occlusal splints to conventionally created splints, while one examined if the use of a facebow influences the performance of digital splints. Visual assessment scores or numerical rating scales of pain, optical axiography, tooth wear, and bruxism frequency were reported as outcomes. Conclusions. Computer aided design occlusal splints provide equivalent outcomes to traditional splints. Some generated superior results, mainly probable as a result of the virtual articulator's greater precision and the splint materials' material qualities.

This study presents findings from a user-based evaluation of the use of Pakistani university's library websites. A questionnaire [printed and electronic] was used to collect the data from 17 universities. A purposive sample of 60 users from each university based on their academic role difference [faculty, researchers, graduates and undergraduates] was drawn. The findings of the study show that use of university library websites in Pakistan was satisfactory. Patrons who frequently used the Internet and library were found as frequent users of the library websites. University websites were found to be vital sources of awareness about the presence of the library websites and computers physically available at the university libraries were the significant places to use the library websites. Regarding users' academic role difference, faculty connected to the library websites from departments/faculties, while researchers and students preferred to use them from university libraries. The library websites were mainly used to find course related materials or search in online public access catalogue (OPAC). However, on the basis of users' academic role difference, faculty used the library websites to search in Higher Education Commission (HEC) Digital Library offering international scholarly literature; researchers accessed them to search in OPAC, while students preferred them to find course-related materials. The study recommends creating dynamic websites in all university libraries of Pakistan with useful content and state-of-the-art services for wider use

AIM: To analyse and characterize the pattern of working and mobile phone usage distances for common users of electronic devices and computers. METHODS: Transversal descriptive study consisting of a screening campaign evaluating the visual status of different professionals working with computers or electronic devices more than 2h per day. A total of 100 healthy patients with a mean age of 41.2 (range: 20-62) years were revised and subdivided according to job subgroups. A battery of screening tests was performed to all participants in a single session at the working environment of each of them, including measurement of the working distance (WD), arm length, and mobile phone usage distances (MPUD). RESULTS: The WD was significantly longer than MPUD (61.22±12.35 vs 32.22±6.35 cm; P<0.001). Likewise, MPUD was significantly shorter than the arm length (74.44±4.65 cm; P<0.001). A total of 4% (4/100) and 91% (91/100) of patients had a WD and MPUD of 40 cm or below, respectively. A weak although statistically significant correlation was found between WD and MPUD (r=0.387, P<0.001) as well as between WD and arm length (r=0.260, P=0.009). Statistically significant differences were detected among job subgroups in WD (P=0.021), being longer for militaries compared to university researchers and lecturers (P=0.025). CONCLUSION: Working and mobile phone usage distances vary significantly among common users of computers and digital devices, although the use of mobile phones tends to be performed at significantly closer distances. This parameter should be considered when planning any type of optical correction, especially for presbyopia.

Within the framework of this research, on the basis of the dialectical unity of its legal and mathematical components, on the basis of general scientific (analysis, synthesis, deduction and induction, abstraction, structural and functional method) and special research methods (formal-legal, method of legal construction, formal-logical, system, technical-legal analysis, statistical method, methods of mathematical statistics and probability theory, etc.), a model of digital legal proceedings in Russia is proposed. The article explains the optimal variant between the components of the digital legal proceedings model in Russia, as well as providing an analysis and evaluation of the effectiveness of the digital legal proceedings model and the prospects for the development of digital legal proceedings. It is concluded that there is a need to develop legal regulation in terms of introducing the definition of “electronic evidence”, types of electronic evidence; it is recognized as a positive practice of implementing a video-conferencing system that ensures the implementation of citizens’ rights to participate in a court session, which significantly reduces the time for case consideration; the need to create a single Internet portal for receiving, processing, and providing electronic documents by all authorities in Russia is explained. In this research, it is explained that the use of mathematical algorithms in evaluating evidence and modeling the behavior of participants in trials is now at an early stage of development, which allows them to be used only in the consideration of similar cases.

Abstract Introduction Recent advances in information technology and improved access to the internet have led to a rapid increase in the adoption and ownership of electronic devices such as touch screen smartphones and tablet computers. This has also led to a renewed interest in the field of digital health also referred to as telehealth or electronic health (eHealth). There is now a drive to collect these PROs electronically using ePRO systems. Method However, the user interfaces of ePRO systems need to be adequately assessed to ensure they are not only fit for purpose but also acceptable to patients who are the end users. Usability testing is a technique that involves the testing of systems, products or websites with participants drawn from the target population. Usability testing can assist ePRO developers in the evaluation of ePRO user interface. The complexity of ePRO systems; stage of development; metrics to measure; and the use of scenarios, moderators and appropriate sample sizes are key methodological issues to consider when planning usability tests. Conclusion The findings from usability testing may facilitate the improvement of ePRO systems making them more usable and acceptable to end users. This may in turn improve the adoption of ePRO systems post-implementation. This article highlights the key methodological issues to consider and address when planning usability testing of ePRO systems.

The process of introducing digital technologies in mining has an evolutionary character and began with the appearance of electronic computing machines at large enterprises, design and scientific organizations. At the initial stage, solving the tasks of mining technology with the use of computers was mainly of demonstration character. Development of works in this branch has led to differentiation of the general task into separate areas: mining-geological information systems (MGIS); geomechanical safety ensuring systems; dispatching systems; programs for solving individual tasks of mining technology. One of the most important directions of digital transformation is mining-geological information systems (MGIS), the development of which went, as a rule, from solving tasks of deposit reserves estimation to modeling of mining technology objects, tools for solving surveying tasks, design and planning of mining works. Evaluating the functionality of MGIS known in the Russian market, we can state that the achieved development level generally meets the requirements of a Digital Mine - the way of representation of objects and processes of mining technology as digital models describing the properties and behaviour of real objects in a single digital space of the enterprise. The next stage of digital transformation is a Digital Twin, which can be characterized as a Digital Mine that has on-line communication links between real equipment units and their digital models. Creation of the Digital twin implies real-time reproduction of the natural-engineering system functioning, reflecting its actual or forecasted state.

<p class="AbstractEnglish"><strong>Abstract: </strong>Developing digital learning innovation with the Blended POE2WE model aims (1) to access knowledge without time and space limitation, (2) to establish internet-based communication, (3) to make learning easier and more enjoyable, and (4) to create more interactive and innovative learning process. The method was literacy (library study). Electronic Data Processing was used to manipulate data into more useful information. Data is a raw object, not processed yet and going to be processed. Meanwhile, information is processed data and becomes other useful data. Digital learning is the product of industrial revolution 4.0. It deals with a large collection of computers in networks that are tied together so that many users can share their vast resources. Besides, the Prediction, Observation, Explanation, Elaboration, Write and Evaluation (POE2WE) learning model was developed from the POEW learning model and the Physics learning model with a constructivist approach. As a consequence, Blended Learning is used to synthesize face-to-face learning and online-based learning into an integrated mix so that can create a high, efficient, and attractive impact. Blended learning practically means that learning (classroom-based learning) is also facilitated with other electronic formats (e-learning) to create an optimal learning program. This is due to that the use of e-learning is very superior compared to Conventional Learning (face-to-face).</p><p class="AbstractEnglish"><strong>Abstrak: </strong>Pengembangan inovasi pembelajaran digital dengan model <em>Blended POE2WE</em><em> </em>bertujuan untuk<em> </em>(1) mengakses pengetahuan setiap saat tak terbatas waktu dan tempat (2) menjalin komunikasi berbasis internet (3) menciptakan pembelajaran lebih mudah dan menyenangkan.

As agent technology is expected to become a possible base platform for an electronic services framework, especially in the area of Electronic Commerce, reliable security protection is a crucial aspect, since some transactions in this area might involve confidential information, such as credit card number, bank account information or some form of digital cash, that has value and might therefore be attacked. In addition, without proper and reliable security protection, the wide spread use of agent technology in real world applications could be impeded. In this paper, evaluation of the Recorded State Mechanism (RSM) previously proposed by the authors is presented. The evaluation examines the RSM security protection and implementation overhead, in order to analyse the RSM security strength and implementation feasibility in real world application.

Recent advances in materials, mechanics, and electronic device design are rapidly establishing the foundations for health monitoring technologies that have “skin-like” properties, with options in chronic (weeks) integration with the epidermis. The resulting capabilities in physiological sensing greatly exceed those possible with conventional hard electronic systems, such as those found in wrist-mounted wearables, because of the intimate skin interface. However, most examples of such emerging classes of devices require batteries and/or hard-wired connections to enable operation. The work reported here introduces active optoelectronic systems that function without batteries and in an entirely wireless mode, with examples in thin, stretchable platforms designed for multiwavelength optical characterization of the skin. Magnetic inductive coupling and near-field communication (NFC) schemes deliver power to multicolored light-emitting diodes and extract digital data from integrated photodetectors in ways that are compatible with standard NFC-enabled platforms, such as smartphones and tablet computers. Examples in the monitoring of heart rate and temporal dynamics of arterial blood flow, in quantifying tissue oxygenation and ultraviolet dosimetry, and in performing four-color spectroscopic evaluation of the skin demonstrate the versatility of these concepts. The results have potential relevance in both hospital care and at-home diagnostics.

Abstract This research explored the potential for ink-jet printing to replicate the coloration and finishing techniques of traditional denim fabric and standardized the reproduction and evaluation procedure. Although denim fabric is widely consumed and very popular, one drawback to denim is that the finishing and manufacturing processes are energy and water intensive and can cause environmental hazards as well as generation of pollution through water waste, particularly at the finishing stage. Textile ink-jet printing has the potential to replicate some of the coloration and finishing techniques of traditional denim fabric without negative environmental impacts. A two-phase research project was conducted. In Phase I (P1), an optimal standard production workflow for digital denim reproduction (including color and finishing effects) was established, and six different denim samples were reproduced based on the workflow. In Phase II, an expert visual assessment protocol was developed to evaluate the acceptance of the replicated digital denim. Twelve ink-jet printing, color science, and denim industry experts finished the assessment.

<span>The purpose of this study is to create a digital educational game that promotes algorithmic thinking for elementary school students. However, the processes of game development differ from traditional software development which cannot guarantee its effectiveness in terms of human-machine interfaces. In this article, we propose a new game development software engineering (GDSE) as a model for game development. This new model aims to complement and mitigate the shortcomings of traditional software development. The principles of human-computer interaction are now incorporated in the new model. The GDSE includes design, development, usability inspection, game experience evaluation, educational value evaluation and release. It was used as a research method to develop a game that promotes algorithmic thinking for children. The results of this study are not only a digital educational game that promotes algorithmic thinking for children but also a new game development life cycle that guarantees the performance of digital games in terms of usability enhancement, game experience and educational value.</span>

When performing digital image processing, the most critical technology that affects its use effect is the autofocus technology. With the advancement of science and the development of computer technology, autofocus technology has become more and more widely used in various fields. Autofocus technology is a key technology in robot vision and digital video systems. In order to allow digital image processing technology to better serve humans, it is necessary to further improve the focus evaluation function algorithm. This article focuses on the imaging principle of defocused images, using different evaluation functions to analyze and process the experimental images to observe the changes in image clarity. Through the introduction and analysis of the existing evaluation function, it can be known that the focus evaluation function will directly affect the quality of digital image processing. Therefore, it is best to choose unimodality, unbiasedness, low noise sensitivity, wide coverage, and a small amount of calculation. For the evaluation function, the Laplacian gradient function is an ideal choice. However, because the current digital image processing technology is not perfect enough, the focus function is still prone to multiextreme problems when the image is severely defocused and the high-frequency components in the image are missing; the balance between image processing speed and focus accuracy also still needs to be improved. Therefore, this paper studies the autocontrol microscope focus algorithm based on digital image processing, analyzes the principle of visual image imaging, and makes some improvements to the microscope focus algorithm. Through experiments, it can be seen that the real-time data of the original Laplace function in the edge-obvious target is 76.9, and it reaches 77.6 after improvement. The improved algorithm can better maintain the single-peak state during the focusing process, which improves the image processing efficiency while ensuring the measurement accuracy.

This paper presents the results of an exploratory survey of African Consumers’ Perception Regarding consumer electronics products originating from its three major trading partners-China, Japan and United States of America (U.S.A). The focus of the study is investigating the source of information in evaluating foreign products, The evaluation of the specific product cues used by African consumer in their assessment of electronic products and the ranking of the three countries-China, Japan and USA in terms of the various product attributes. The product category selected for the study includes television sets, Refrigerators, Computers, Electric irons, and digital cameras. The products cues (Dimensions) used for the study comprised of Country of origin image (COI), Brand Familiarity (B.F), Perceived product quality (PPQ), Firms’ trust (F.T), Country reputation (C.R), Economic Animosity (E.A), Perceived product price (PPP), And Product Availability (P.A). Data was collected from two hundred and seventy (270) African consumers in the city of Wuhan Hubei province; Peoples Republic of China. With the aid of statistical packages for social sciences (IBM SPSS 20 VERSION), Paired-sample T test was used to compare the mean ratings of all the eight (8) product dimensions for all the pairs of the three (3) countries. The findings showed that internet advertisement and television are the most important information sources used by African consumers in evaluating foreign electronic products, this was followed by friends’ opinion and the least patronage was radio. The result also disclosed that African consumers don’t consider the country of origin aspect to be their priority in the course of making foreign electronic product purchase, rather other product attributes such as quality and product brand take the precedence. Also revealed from the studies is the ranking of the three countries in terms of the eight product dimensions. It was found that, Japan having highest brand recognition (Brand familiarity), United states would boast of two things, which include high perceived product quality and country reputation. China is leading ahead in terms of cheap product price and availability of their products in almost (if not all) the nooks and crannies of African countries as perceived by African consumers. Finally, in discussing managerial implications, prescriptions were made to marketers from different countries for improving their competitiveness in the emerging African market given the present perceptions of the African consumers.

<span lang="EN-US">Avatar design types can range from human representations to abstract representations. In digital educational games (DEGs), avatars are frequently used to encourage users to play the game. However, the role of avatar design types and their engagement in digital games are still unclear and empirically under research. Therefore, a bespoke digital educational game in geography was developed and validated by six expert users. Then forty-five users participated in the evaluation phase to investigate engagement and avatar types on digital educational games using the user engagement scale (UES). The results reported aesthetics and satisfaction factors somehow influenced the avatar design types, but none of the UES subscales was influenced by preferred avatar design types. Moreover, the human-cartoon avatar, which was not entirely human and cartoonish, was the most popular avatar design type among young adults. Other issues discussed for future developers and research included incorporating more avatar design selections into the study, integrating social interaction features into the game, using the same drawing style for avatars and provide easy access to the bespoke game during data collection.</span>

Abstract Background Digital availability of patient data is continuously improving with the increasing implementation of electronic patient records in physician practices. The emergence of digital health data defines new fields of application for data analytics applications, which in turn offer extensive options of using data. Common areas of data analytics applications include decision support, administration, and fraud detection. Risk scores play an important role in compiling algorithms that underlay tools for decision support. Objectives This study aims to identify the current state of risk score integration and integration capability in electronic patient records for cardiovascular disease and diabetes in German primary care practices. Methods We developed an evaluation framework to determine the current state of risk score integration and future integration options for four cardiovascular disease risk scores (arriba, Pooled Cohort Equations, QRISK3, and Systematic Coronary Risk Evaluation) and two diabetes risk scores (Finnish Diabetes Risk Score and German Diabetes Risk Score). We then used this framework to evaluate the integration of risk scores in common practice software solutions by examining the software and inquiring the respective software contact person. Results Our evaluation showed that the most widely integrated risk score is arriba, as recommended by German medical guidelines. Every software version in our sample provided either an interface to arriba or the option to implement one. Our assessment of integration capability revealed a more nuanced picture. Results on data availability were mixed. Each score contains at least one variable, which requires laboratory diagnostics. Our analysis of data standardization showed that only one score documented all variables in a standardized way. Conclusion Our assessment revealed that the current state of risk score integration in physician practice software is rather low. Integration capability currently faces some obstacles. Future research should develop a comprehensive framework that considers the reasonable integration of risk scores into practice workflows, disease prevention programs, and the awareness of physicians and patients.

The domestic cultural and creative industry has abundant resource advantages and broad development space. The design for cultural and creative products has evolved rapidly with the objective to improve its quality. The cultural and creative industries have seen rapid growth in the recent years wherein digital technologies have been incorporated with the traditional methodologies. The digital cultural and creative aspect acts are extremely important in the dissemination of traditional culture on the network platform. This is also supported by the state vigorously to implement innovative industrial policies. However, the adoption of digital technology in the cultural and creative industry is a novel approach. But there exists lack of understanding in terms of its nature and development protocols. It is thus necessary to study relevant theories to guide the development of digital cultural and creative industry. The increasingly prosperous aesthetic culture, especially development for cultural and creative industries, has comprehensively improved aesthetic value of the cultural and creative products. Therefore, the methods to evaluate and realize the aesthetic value of digital, cultural, and creative products are extremely important and relevant in the present day and age. In this study, neural network is used to design an improved back propagation (BP) network in order to evaluate the aesthetic value of digital cultural and creative products. At the outset, the basic idea, structural characteristics, the learning algorithm, and its flow of functioning in the BP network are analyzed. Then, an aesthetic value evaluation model of digital cultural and creative products with BP network is developed. Next, considering the shortcomings of BP network, a segmentation adaptive strategy is used to improve the view field and step size for artificial fish swarm algorithm (AFSA). Finally, the improvised algorithm is verified wherein the simulation results reveal improvement in algorithm convergence speed as well as improvement in optimal solution accuracy as part of the adaptive improvement approach.

Purpose It has been a decade, as the collaboration between the Ghana Investment Fund for Electronic Communications (GIFEC) and the Ghana Library Authority (GhLA) to extend information and communication technology (ICT) and library services to rural deprived, unserved and underserved communities in Ghana dubbed the library connectivity project. This paper aims to evaluate this initiative from the perspective of relevant key stakeholders and through the lens of the digital inclusion model. Design/methodology/approach The study adopted a qualitative approach to evaluate the library connectivity project offered to deprived communities in the Upper East Region of Ghana. Interviews were conducted with the head librarians, ICT teachers and school librarians. Focus group discussions were held with pupils from four beneficiary schools of the project. The researchers also witnessed four of the outreach programmes and training sessions and observed the mode of instruction. Findings The study brought to fore the enormous benefits of the library connectivity project as it aided school pupils to acquire practical ICT skills, which were found to be useful towards their final exam. Despite the enormous benefit of the project, it was bereft with a lot of challenges such as inadequate logistics and personnel thereby restricting the project to very few schools. Low staff motivation and unmotorable roads were also found to be a challenge, which could all be as a result of lack of funds. Research limitations/implications The paper underscores the importance of computer and information literacy and reveals how the GhLA is using innovative mobile library services to bridge the digital divide through the library connectivity project. Originality/value This paper makes a further contribution to the paucity of literature on the role of mobile libraries in the promotion of computer and information literacy.

Currently, digital transformation has occurred in most countries in the world to varying degrees, but digitizing business processes are complex in terms of understanding the various aspects of manual documentation. The use of digital devices and intelligent systems is vital in the digital transformation of manual documentation from hardcopy to digital formats. The transformation of handwritten documents into electronic files is one of the principal aspects of digitization and represents a common need shared by today’s businesses. Generally, handwriting recognition poses a complex digitization challenge, and Arabic handwriting recognition, specifically, proves inordinately challenging due to the nature of Arabic scripts and the excessive diversity in human handwriting. This study presents an intelligent approach for recognizing handwritten Arabic letters. In this approach, a convolution neural network (CNN) model is proposed to recognize handwritten Arabic letters. The model is regularized using batch normalization and dropout operations. Moreover, the model was tested with and without dropout, resulting in a significant difference in the performance. Hence, the model overfitting has been prevented using dropout regularization. The proposed model was applied to the prominent, publicly-available Arabic handwritten characters (AHCD) dataset with 16,800 letters, and the performance was measured using several evaluation measures. The experimental results show the best fit of the proposed model in terms of higher accuracy results that reached 96.78%; additionally, other evaluation measures compared to popular domain-relevant approaches in the literature.
