Resource Indexing and Querying in Large Connected Environments

The proliferation of sensor and actuator devices in Internet of things (IoT) networks has garnered significant attention in recent years. However, the increasing number of IoT devices, and the corresponding resources, has introduced various challenges, particularly in indexing and querying. In essence, resource management has become more complex due to the non-uniform distribution of related devices and their limited capacity. Additionally, the diverse demands of users have further complicated resource indexing. This paper proposes a distributed resource indexing and querying algorithm for large connected environments, specifically designed to address the challenges posed by IoT networks. The algorithm considers both the limited device capacity and the non-uniform distribution of devices, acknowledging that devices cannot store information about the entire environment. Furthermore, it places special emphasis on uncovered zones, to reduce the response time of queries related to these areas. Moreover, the algorithm introduces different types of queries, to cater to various user needs, including fast queries and urgent queries suitable for different scenarios. The effectiveness of the proposed approach was evaluated through extensive experiments covering index creation, coverage, and query execution, yielding promising and insightful results.

The Role of New Media Technologies in Improving Communication Skills of Intellectual Disabled Individuals

The communication and social skills of individuals with mental disabilities are considerably behind their peers with normal development. These individuals’ educational needs vary depending on their distinct traits. There is an increasing need to improve communication skills in order to minimize the problems experienced by these mentally handicapped individuals in the family, at school, at all levels of social life, and in interpersonal relationships. Considering their characteristics, educational environments designed for these individuals should be set up in such a way that they can make full use of educational opportunities. Emerging from the application of computer and information-processing developments to the field of communication and starting to direct the relations between individuals with the use of the Internet and technological devices together, new media has also been introduced into educational environments, and changes have started to be seen in the educational processes of individuals with intellectual disabilities. New media technologies aim to optimize learning settings for students who show different developmental characteristics than their peers and learn differently from them. Educational environments where new media technologies are used as auxiliary materials provide these individuals the opportunity to learn individually in line with their own abilities and therefore improve the quality of education. New media technologies support the development of communication skills in individuals with mental disabilities, as well as their reading, writing, and math skills, according to their disability area. This study, in this regard, provides information on the development of communication skills in individuals with mental disabilities to socially integrate and conduct interpersonal interactions in a healthy way and offers suggestions for the use of new media tools to improve the communication skills of individuals with mental disabilities.

Students' Perception of Oral Presentation Assignment Using PowerPoint in English Education Students

In the English classroom, students are assigned to conduct oral presentations using PowerPoint as one of the visual aids. The study aimed to investigate the perceptions of English education students about oral presentations and classroom assignments using PowerPoint. The researchers employed qualitative methods and purposively selected a sample of 30 college students in the 5th semester of English education at one of the higher education institutions in Indonesia. The research instruments were Likert scale questionnaires and interviews. The data analysis used a thematic analysis. The result indicated that most students' perceptions were positive towards oral presentations using PowerPoint, which served as an assignment. Also, it highlights that oral presentations can enhance students' understanding and retention if the slides contain only important points, interesting pictures, or animation rather than full text. This research pointed out that students thought oral PowerPoint presentations were inefficient due to external factors such as a lack of internet connection and device preparation. Therefore, the oral presentation assignments using PowerPoint become necessary by considering the learning activity to obtain the learning objectives.

Then, the data that has been compiled is analyzed to obtain results. After getting the results, visualization is carried out using VosViewer to get an overview of the data that has been obtained. The results of this research show that online learning is divided into 3 clusters, namely the first cluster is online learning and education, the second cluster is Covid, and the third cluster is online learning and the Covid pandemic period. It can be concluded that online learning is a form of distance learning or training that utilizes technology as a telecommunication tool such as the internet and other devices. It has been widely implemented since the onset of the Covid-19 pandemic in Indonesia. The implementation of online learning has gone well, but there are still many shortcomings.

Blockchain Ethics

There is no question about the innovation force and the economic potential of blockchain technology. As the basis for new currencies, financial services, and smart contracts, blockchain technology can be seen as the fifth disruptive computing paradigm, after mainframes, personal computers, the Internet, and mobile devices. However, there are questions about its ethical implications, which have the potential to also impact the economic success of blockchain technology. This article aims to provide ethical guidance on blockchain technology. In order to reach this goal, the focus of the ethical analysis will first concentrate on the unique characteristics of blockchain technology compared to other technology-based innovations. The unique nucleus of blockchain technology can be defined as a move from the trust in people to a trust in math, as a move from an internet of information to an internet of value, or—as I would propose—a shift from an intermediated network to an immediate network. Second, the ethical opportunities (e.g., transparency, participation, global access to services) and risks (e.g., ecological impact, lack of legal monitoring and enforcement) associated with this unique nucleus of blockchain technology will be discussed. Third, an outlook on possible concrete solutions will be provided.

Oral vs. Touch Interaction for Cognitive Assessment: Acceptance and Perceived Usability by Senior Adults

There is a digital divide between senior adults and the general population because of the disparity in access and usage of digital technologies, including the internet and modern devices, often stemming from factors like age, familiarity, and socioeconomic status. Yet, technology is increasingly penetrating the healthcare sector in areas such as screening, diagnosis, treatment, and follow-up. This study focuses on investigating how older adults perceive the introduction of new devices in the screening and diagnosis of cognitive impairment. For this, a perception study was carried out involving 25 senior adults, 16 women and 9 men, aged between 60 and 93 years, living in the Vigo area, Spain. First, the perception and acceptability of popular technological devices were evaluated by means of the technology acceptance model. Then, participants’ perceptions about the use of smart speakers and tablets for cognitive evaluation were analyzed, both before and after interacting with such devices. Finally, the perception of their caregivers about these tools was also studied. These instruments were found to be useful and enjoyable by older adults. More specifically, smart speakers were preferred by participants over traditional tests for detecting cognitive decline. Additionally, there were no significant differences in the perception of utility, ease of use, or enjoyment between tablets and smart speakers. Participants’ caregivers also reported an overall positive perception about the introduction of these new tools for cognitive assessment. In any case, the study provided evidence to support the introduction of both tablets and smart speakers to interact with older adults, and more specifically, as a means to facilitate the early detection and screening of cognitive decline.

Obstacles that often arise in the implementation of online meditation are signals, internet data quotas, devices and environmental noise disturbances.

Gamelan Land: A Multiplayer Virtual Reality Game based on a Social Presence Approach

A Multiplayer Virtual Reality Game (MVRG) was developed in order to support experiences in learning and playing orchestral music through a virtual world called the Gamelan Land (GL) game. The GL game was aimed as a virtual place to support interaction between musicians and Gamelan enthusiasts who are spread all over the world. It supports them carrying out Gamelan community activities in the real world into a virtual world through immersive virtual experiences. The story developed in the GL game reflects the real life of the Gamelan community. Oculus Quest 2 which is a Head Mounted Displays (HMD) device that can deliver highly immersive 3D environments was selected as the platform to run the Gamelan music MVRG provided in the GL game. The performance of the Gamelan music MVRG shows promising results. Improvement of audio and visual latency in playing music in orchestra is still a problem to be solved. The problem can be caused by differences in internet network speed and device specifications. So far, low poly 3D models can be an alternative solution. Moreover, although it still requires testing involving more users and longer time, the social presence approach in the GL game can be implemented well and has promising prospects for further development.

Enabling high performance all-solid-state thin films microbatteries with silicon oxycarbide/lithium-metal composites anodes

All-solid-state thin films micro-batteries (ASSTFBs) integrating thin-films technologies with solid-electrolytes are regarded as promising power sources that can inherently alleviate safety issues for the miniaturized devices for internet of things (IoT). However, poor interfacial compatibility and low ionic conductivity induced by using of solid-state electrolytes urgently demand new development of novel materials and preparation technologies. In this work, novel silicon oxycarbide/lithium-metal composites anodes for ASSTFBs of IoT micro-devices are prepared by magnetron sputtering, and the electrochemical performances are systematically investigated via experiments and first-principles. The thin films batteries systems present high first cycle discharge capacities up to 104.15 mAh/g. The sample with the highest carbon content of SiCO shows superior coulomb efficiency of 97 % after 40 cycles and retention rates of 73.29 % at 0.1 C, and sample with the optimal feature size of free carbon presents the most outstanding comprehensive electrochemical properties. First-principles calculations reveal that the optimal LiPON/SiCO interface presents the highest adhesion strength and superior lithium diffusion properties with the lowest energy barrier for lithium diffusion. The relatively larger free carbon network limit volume expansion upon insertion of lithium, and silicon tetrahedral in SiCO show large lithium storage density, leads to improved cycling performance and high lithium capacity of the system.

Post-covid 19 training: users’ perception on the effectiveness of virtual learning environments for skill acquisition

The Coronavirus Disease (COVID-19) is an infectious disease which originated from Wuhan, China in December of 2019 which quickly spread across the world rapidly through the movement of people and goods at an exponential and alarming rate infecting and killing millions. In Nigeria and across the world steps were taken to suppress and control the spread of the Covid-19 including closing of schools, universities, training institutions, event centres, markets and other places of public gatherings. While closing education institutions were important in mitigating the spread of COVID-19, prolonged closures negatively impact learners of all categories and disproportionately affected all forms of learning and trainings. This situation therefore called for creating opportunities for learner to learn and acquire skills virtually. The adoptions of Virtual Learning Environments (VLE) and platforms as became the order of the day. Virtual learning environments are web based platforms for digital solution aimed at creating interactive and an active learning environments. VLEs help create, store and disseminate course content, lessons and foster communication between learners and teachers. They play an essential role by providing users with learning flexibility and unprecedented opportunities to co-create information. VLE platforms such as Microsoft Teams, Zoom, Webinars, Google Classroom, Moodle etc. allows students to study at their own pace and automatically tracking their progress as they collaborate and learn. The use of online and virtual learning platforms is here to stay but this reality is threatened by the perception of end users which always determine the effective of such platform for skill acquisition. This can be linked to the fear of unknown future, lack of technical abilities to use this platforms, comfort in the traditional in person or face to face mode of learning, lack of adequate infrastructure such as internet facilities, smartphones and devices. The main purpose of this study is to investigate the Post-Covid 19 Training: Users Perception on the Effectiveness of Virtual Learning Environments for Skill Acquisition.

Digital Copyright Management Mechanism Based on Dynamic Encryption for Multiplatform Browsers

In recent years, the internet and smart devices have developed rapidly. Many people no longer rely on newspapers, magazines, or television to receive news. They can see the latest news using computers or mobile phones. According to a study by the Taiwan Internet Information Center, nearly 90% of Taiwanese people have used the internet. Many online streaming services have emerged, and people can easily watch movies and TV programs through computers or mobile phones. Hence, some websites use digital copyright management mechanisms to protect videos from being directly downloaded. However, 30% of websites use AES-128 encryption to protect their content. If the key access mechanism is not well protected, the encryption methodology may be useless. Therefore, this paper proposes a cross-platform digital copyright management mechanism for adaptive streaming. With this mechanism, users do not need to download additional applications, as the mechanism implements Web-Assembly language through the browser.

Informational inequality: the role of resources and attributes in information security awareness

PurposeThe rapid expansion of internet usage and device connectivity has underscored the importance of understanding the public’s cyber behavior and knowledge. Despite this, there is little research that examines the public’s objective knowledge of secure information security practices. The purpose of this study is to examine how objective cyber awareness is distributed throughout society.Design/methodology/approachThis study draws on a large national survey of adults to examine the relationship between individual factors – such as demographic attributes and socioeconomic resources – and information security awareness. The study estimates several statistical models using weighted logistic regression to model objective information security awareness.FindingsThe results indicate that socioeconomic resources such as income and education have a significant effect on individuals’ information security awareness with richer and more highly educated individuals exhibiting greater awareness of important security practices and tools. Additionally, age and gender represent consistent and clear informational gaps in society as older individuals and females are significantly less knowledgeable about an array of information security practices than younger individuals and males, respectively.Social implicationsThe findings have important implications for our understanding of information security behavior and user vulnerability in an increasingly digital and connected society. Despite the growing importance of cybersecurity for all individuals in nearly all domains of daily life, there is substantial inequality in awareness about secure cyber practices and the tools and techniques used to protect one’s self from attacks. While digital technology will continue to permeate many aspects of daily life – from financial transactions to health services to social interactions – the findings here indicate that some users may be far more exposed and vulnerable to attack than others.Originality/valueThis study contributes to our understanding of general user information security awareness using a large survey and statistical models to generalize about the public’s information security awareness across multiple domains and stimulates future research on public knowledge of information security. The findings indicate that some users may be far more exposed and vulnerable to attack than others. Despite the growing importance of cybersecurity for all individuals in nearly all domains of daily life, there is substantial inequality in awareness about secure cyber practices and the tools and techniques used to protect one’s self from attacks.

Fatigue and mind-wandering among Chinese adolescents: Moderation by rumination and mediation by Internet addiction

This study examined the mediating role of Internet addiction in association with fatigue and mind-wandering and the moderating role of rumination in that relationship. A sample of 3 732 Chinese adolescents (Mean age = 14.98 years, SD = 1.63) completed measures of fatigue, Internet addiction, rumination, and mind-wandering. Structural equation modelling (SEM) results showed that higher fatigue was associated with higher mind-wandering. Internet addiction played a mediating role in this relationship and was associated with an increased risk for fatigue. Additionally, rumination moderated the association between Internet addiction and mind-wandering and exacerbated the risk for fatigue. The findings indicate a need for mind-wandering interventions for school students to reduce the risk for fatigue associated with their use of Internet devices and associated ruminations.
