PROTECTION OF INFORMATIONAL PRIVACY IN THE WORKPLACE GIVEN THE ADVANCEMENT IN TECHNOLOGY

The introduction of electronic communication in the workplace has changed how employers conduct their business and, in turn, the way that employees are expected to perform their duties. Increased electronic communication services in the workplace have infused the physical employment environment with electronic communication technology. The increase in this form of communication threatens the employee’s right to privacy in today’s workplace, which is characterised by reliance on information communication technology (ICT), and in particular, the use of emails and the Internet to conduct business. The purpose of this article is to suggest a frame of reference that could assist with the implementation of the Protection of Personal Information Act (4 of 2013) (POPIA) by organisations that process personal information in South Africa based on the conditions provided in POPIA.

Ghosted: Challenges to Conducting Qualitative Research in the Digital Era

Electronic forms of communication—including email, texting, and social media platforms—have increased the speed and ease of communication. Yet, a rise in non-response and ghosting (when someone ceases communication without an explanation) has been documented across contexts, from romantic dating to quantitative research studies. Surprisingly, the rise of electronic communication has received little attention in the methodological literature for qualitative researchers. Based on an analysis of virtual and face-to-face recruitment in two qualitative studies I conducted, I find that ghosting is a routine feature of digital recruitment. There are situational contexts in which ghosting is more common, including lags in the timing of communication and requests that are too overwhelming. “Old-school” methods, such as seeking sponsorship, strategizing outreach, and building rapport, can be adapted to help researchers capitalize on the benefits of electronic communication technologies in recruitment.

Design and implementation of intelligent‐oriented electronic communication power monitoring system

AbstractIn order to improve the monitoring effect of electronic communication power supply, this paper applies the intelligent communication signal processing method to the monitoring system, and deeply analyzes the basic principle of OTA. Moreover, from the perspective of improving linearity, a signal attenuation OTA is designed in this paper, and its linearity has been greatly improved. In addition, this paper designs a cross‐coupled POTA that can not only ensure high linearity but also achieve tunable translinearity. The tunable POTA circuit has simple structure, wide linear input range, tunable translinearity and easy implementation, and can meet its performance requirements in FPAA arrays. Through data analysis, it can be seen that the intelligent‐oriented electronic communication power monitoring system proposed in this paper has a good data monitoring effect. This study provides an effective approach for the development of electronic communication power monitoring technology, improves the signal processing efficiency of electronic communication power monitoring, and also provides some reference for the improvement of signal strength in electronic communication technology.

The Necessity of Cybersecurity for Community Safety The Proposal of the Safe Family Program for Educating the Gulf Arab Community on Information Security for Both Students and Parents

The contemporary landscape of electronic communication technologies is marked by rapid advancement, diverse modalities, and intuitive interfaces, rendering them widely accessible across demographic strata. Notably, the youth cohort, including school students, exhibits a discernible proclivity towards the utilization of social media networks. Regrettably, this escalating adoptionlacks the concomitant implementation of requisite competencies for judicious technological engagement. Furthermore, a perceptible dearth of cognizance is observed among students regarding the gravity of information security and the attendant repercussions of its neglect. This lacuna has precipitated a proliferation of cybersecurity issues, including hacking and electronic coercion. Despite instances of adept technological acumen among some students, they remain susceptible to exploitation by cyber adversaries. This discourse underscores the imperative for comprehensive educational initiatives aimed at fostering responsible and secure digital practices among the burgeoning generation of technology users. This study conducted a survey among diverse groups of male and female students in the Kingdom of Saudi Arabia to identify the primary issues leading to their vulnerability to cyber intrusions. The objective was to derive necessary recommendations for their protection while engaging in social network activities. The study elucidated the importance of educating students about the ramifications of unsafe technology use, emphasizing the preservation of their electronic privacy. Furthermore, this study addressed the exploration of the role of parents in safeguarding their offspring from the perils of cyber intrusion and extortion. The study conducted a comparative analysis between numerous families wherein parents and children had the opportunity for appropriate training in the use of these technologies and those families lacking such training. This comparative approach aimed to elucidate the role of parents in shielding their children from electronic intrusions. The findings of the study underscored a critically significant role for parents in protecting their children from electronic threats, even in cases where the offspring possessed a sufficient educational background in handling these new technologies. The researcher proposed an educational initiative aimed at preserving electronic privacy forstudents, encompassing all categories of public and private education. In addition, a program for parental education was introduced, targeting both mothers and fathers. The objective of this program is to contribute to the elevation of societal security awareness and the protection of children from the imminent dangers posed by electronic threats.

Self-powered sensors for flexible electronic skins capable of self-healing under multiple extreme environments

With the advancements in electronic skins (E-skins) and communication technologies, the applicability of sensors in extreme environments poses significant challenges. While various sensors have been reported, maintaining electrical output performance without external power source and self-healing capability across multiple extreme environments remains a hurdle. Herein, we present flexible, self-healing, and harsh environment-resistant self-powered sensors for E-skins, the self-healing capabilities of which are virtually invulnerable in diverse extreme environments, including underwater, saline, oxidized, alkali, and acid conditions, as well as low and high temperatures. The self-powered sensors are composed of self-healing polyurea (SH-PUrea) and Ag nanowires (AgNWs). Since physical entanglements that are less susceptible to environmental influences are introduced in SH-PUrea, the self-powered sensors exhibit exceptional self-healing performance without degradation of the output signals, regardless of the ambient conditions or extreme environments encountered. Specifically designed in a 3 × 3 pixel array structure, the self-powered sensors are ideal for E-skins that can adapt to sweaty and underwater environments. The detection of pressure position and underwater communication can be achieved by analyzing the electrical signals from the sensor array. This work introduces a novel strategy for enhancing the extreme environment-resistance and durability of flexible devices.

Impact of service effectiveness and telemedicine use on patient satisfaction using telemedicine X hospital, Semarang City in Covid-19 pandemic

Background: Since the outbreak of Corona Virus Disease (COVID-19), face-to-face services were initially limited, and communication between doctors and patients during a pandemic was less effective, so health services changed. Telemedicine, which was initially only communication between hospital departments or between hospitals, has become all kinds of communication, such as patient-doctor, patient-nurse, patient-pharmacy and so on, using Telemedicine. The use of telemedicine services is one of the strategies to prevent the spread of COVID-19 because Telemedicine provides health services using electronic communication technology. Patients and medical personnel do not need to meet in person in one place but still communicate through the application. Patient satisfaction in using Telemedicine is a crucial and vital indicator that needs to be considered to improve the quality of telemedicine medical services.Objectives: To analyze the relationship between the effectiveness of services and the use of Telemedicine on patient satisfaction using Telemedicine.Methods: Quantitative with a retrospective descriptive research design. Data was collected using an online questionnaire for 350 patients at Hospital X in Semarang City. Patients who met the inclusion and exclusion criteria were taken by purposive sampling. The analysis of this study included univariate, bivariate, and multivariate analyses. The chi-square test and logistic regression were used in this study.Results: Regarding the effectiveness of the service and use of Telemedicine, most respondents rated the service's effectiveness as good, 139 (92,1%) of respondents, and the majority of respondents considered the use of Telemedicine to support as many as 136 (90,1%) of respondents. Patient satisfaction showed that most respondents were satisfied, as many as 140 (92,7%) respondents. The relationship between service effectiveness and patient satisfaction demonstrates that the service effectiveness variable is significantly related to patient satisfaction (p-value = 0,006 ≤ Level of Significant = 0,05). The relationship between telemedicine use and patient satisfaction shows that telemedicine use has a significant relationship with patient satisfaction (p-value = 0,014 ≤ Level of Significant = 0,05).Conclusion: most of the respondents rated the effectiveness of the service as good, most of the respondents supported the use of Telemedicine, most of the respondents were satisfied, and the variable of service effectiveness was significantly related to patient satisfaction.

AgNWs/Fe3O4@NC Conductive Network Hierarchical Assembly to Prepare Flexible EMI Shielding Textile.

With the rapid development of high-power electronic instruments and communication technology, efficient electromagnetic shielding materials with strong absorption of electromagnetic waves and low reflection characteristics have become the focus of the world's attention. This study designs and synthesizes N-doped carbon-coated hollow Fe3O4 nanospheres (Fe3O4@NC) by spraying Ag nanowires (AgNWs) on textiles as conductive networks. Because of the high permeability and hollow structure Fe3O4@NC, electromagnetic wave goes through a unique process of "absorption, reflection, and reabsorption" when it passes through the surface of the composite textile. In X-band (≈8.2-12.4GHz), the average electromagnetic interference shielding effectiveness (EMI SE) reaches 50.1dB, while the reflectance shielding efficiency (SER) is only 2.6dB, and the average reflectance power coefficient (R) is as low as 0.45. The composite fabric has excellent properties and provides an effective strategy for electromagnetic interference shielding based on absorption.

Advances in Bioelectrode Design for Developing Electrochemical Biosensors.

The critical performance factors such as selectivity, sensitivity, operational and storage stability, and response time of electrochemical biosensors are governed mainly by the function of their key component, the bioelectrode. Suitable design and fabrication strategies of the bioelectrode interface are essential for realizing the requisite performance of the biosensors for their practical utility. A multifaceted attempt to achieve this goal is visible from the vast literature exploring effective strategies for preparing, immobilizing, and stabilizing biorecognition elements on the electrode surface and efficient transduction of biochemical signals into electrical ones (i.e., current, voltage, and impedance) through the bioelectrode interface with the aid of advanced materials and techniques. The commercial success of biosensors in modern society is also increasingly influenced by their size (and hence portability), multiplexing capability, and coupling in the interface of the wireless communication technology, which facilitates quick data transfer and linked decision-making processes in real-time in different areas such as healthcare, agriculture, food, and environmental applications. Therefore, fabrication of the bioelectrode involves careful selection and control of several parameters, including biorecognition elements, electrode materials, shape and size of the electrode, detection principles, and various fabrication strategies, including microscale and printing technologies. This review discusses recent trends in bioelectrode designs and fabrications for developing electrochemical biosensors. The discussions have been delineated into the types of biorecognition elements and their immobilization strategies, signal transduction approaches, commonly used advanced materials for electrode fabrication and techniques for fabricating the bioelectrodes, and device integration with modern electronic communication technology for developing electrochemical biosensors of commercial interest.

An Optimized Decision Model for Electric Vehicle Aggregator Participation in the Electricity Market Based on the Stackelberg Game

With the growing popularity of charging pile infrastructure and the development of smart electronic devices and 5G communication technologies, the electric vehicle aggregator (EVA) as a bidding entity can aggregate numerous electric vehicle (EV) resources to participate in the electricity market. Moreover, as the number of grid-connected EVs increases, EVA will have an impact on the nodal marginal prices of electricity market clearing. Aiming at the bidding and offering problem of EVA participation in the day-ahead and intra-day electricity markets, based on the Stackelberg game theory, this paper establishes a bilevel optimization model for EVA participation in the two-stage electricity market as a price-maker. In the proposed bilevel model, the upper-level and lower-level models are constructed as an operational problem for EVA and a market-clearing problem for independent system operator (ISO), respectively. In the day-ahead stage, EVA is optimized to maximize its own expected benefits, and ISO aims to improve the social benefits. In the intra-day stage, EVA is optimized to maximize its self-interest, and the ISO aims to make it possible to minimize the cost of expenditures to maintain the system’s supply–demand balance. Karush–Kuhn–Tucker (KKT) conditions and dual theory are used to transform the nonlinear bilevel programming model into a mixed-integer single-level linear programming model. In order to verify the validity of the proposed bilevel model as well as to comparatively analyze the impact of EVA’s participation in the electricity market on the market clearing results. Two scenarios are set up where EVA is seen as the price-taker in Scenario 1 and EVA is seen as the price-maker in Scenario 2. ISO’s revenue under Scenario 2 increased by USD 2262.66 compared to Scenario 1. In addition, the EVA acts as an energy consumer in Scenario 1 with a charging cost of USD 26,432.95, whereas in Scenario 2, the EVA can profit by participating in the electricity market with a revenue of USD 26,432.95, at which point the EVA acts like a virtual power plant. The simulation examples verify that the proposed bilevel optimization model can improve the benefits of ISO and EVA at the same time, achieving mutual benefits for both parties. In addition, the simulation analyzes the impact of abandonment penalty price on ISO and EVA intra-day revenues. Comparing the scenarios where the abandonment penalty price is 0 with USD 10/MW, the ISO’s revenue in the intra-day market decreases by USD 197.5. Correspondingly, EVA’s reserve capacity is dispatched to consume wind power in the intra-day market, and its revenue increases by USD 197.5. The proposed two-stage bilevel optimization model can provide a reference for EVA to develop scheduling strategies in the day-ahead and intra-day electricity markets.

Fabrication of MWCNTs/rGO/PPy ternary composites for excellent electromagnetic absorption

With the development of radar stealth technology and electronic communication technology, electromagnetic (EM) wave absorbing materials with lightweight and broad absorbing bandwidth are widely expected. In this study, the multi-walled carbon nanotubes (MWCNTs)/reduced graphene oxide (rGO)/polypyrrole (PPy) ternary composites were prepared by in-situ polymerization under hydrothermal conditions. The effects of carbon substrate of MWCNTs/rGO and the content of PPy on the microwave absorption (MWA) properties of the ternary composites and the corresponding attenuation mechanism were investigated. The results showed that MWCNTs and rGO nanosheets interweave together to form a relatively uniform micro-network structure with even wrapping of PPy on the surface of MWCNTs/rGO substrate. The adjustable amount of PPy optimizes the impedance matching and EM wave attenuation capacity. The composites achieve effective absorption bandwidth (EAB) of 4.6 GHz at 2.1 mm, and the minimum reflection loss (RLmin) value of −57 dB at 15.8 GHz. The multi-void network structures formed by MWCNTs and lamellar rGO and the interfacial polarization between MWCNTs/rGO composite carbon substrate and PPy can effectively decay EM wave absorption, thus improving the MWA performance of the composites. This work provides an effective reference for the application of multi-component carbon composites in the field of microwave absorption.

This study aims to investigate whether the integration of electronic communication technology into teaching methods within universities can alleviate students’ learning anxiety and assess the efficacy of this approach.Subjects and MethodsParticipants were selected from a university and divided into an experimental group and a control group. The experimental group underwent classroom teaching using electronic communication technology, encompassing online teaching platforms, virtual laboratories, and other relevant tools. In contrast, the control group received traditional face-to-face teaching. Anxiety questionnaires and academic performance metrics were employed as data collection instruments. Data were analyzed using Stata 8.0 statistical software.ResultsThe learning anxiety scores of students in the experimental group were notably lower compared to those in the control group. Specifically, the average anxiety score for the experimental group was 3.82, while the control group had an average anxiety score of 4.96. Statistical analysis utilizing appropriate methods confirmed a statistically significant difference between the two groups (P<0.05).ConclusionsEmpirical evidence from this study substantiates that the integration of electronic communication technology effectively mitigates symptoms of learning anxiety among students and enhances their learning outcomes. Utilizing online teaching platforms, virtual laboratories, and similar tools empowers students to engage in more self-directed and proactive learning, consequently reducing anxiety that may arise from face-to-face teaching scenarios.AcknowledgementThe Philosophy and Social Science Research Project of Higher Education of Jiangsu Province (No. 2021SJA2140).

Effective electromagnetic interference shields based on cellulose nanofibers-carbon nanotubes layered composites

The rapid development of electronic devices and communication technologies has inadvertently led to the production of significant amounts of Electromagnetic Interference (EMI) and radiation, necessitating the development of sustainable, low-density, affordable, and high-performance EMI shielding materials. The present study involves fabricating a layered composite material comprising alternating substrate and conducting layer made primarily of TEMPO-mediated oxidized cellulose nanofibers (TCNF) and carbon nanotubes (CNT). For the substrate layer, TCNF is modified with optimized polydopamine and Fe3+ concentrations to produce mechanically strong film with a tensile modulus of 12.3 GPa. Furthermore, two CNT/TCNF ratios are used in the conducting film: 60% and 80%. In addition to absorption and reflection, the presence of TCNF in the conducting layer creates an impedance mismatch, resulting in a zigzag reflection mechanism for EMI losses. For a thickness of 212 μm, the 5-layered composite exhibited a notable tensile strength of 58 MPa and an efficient EMI shielding effectiveness (EMI SE) of 39 dB in X-band. The prepared composites meet the requirements for a commercial EMI shielding material, namely >20 dB, and outperform the mechanical strength of many other EMI shielding materials.

Radio frequency identification review and development prospect research

Based on the existing literature and data, this paper starts from the principle of radio frequency identification technology, analyses the situation of the application field of RFID and predicts its development prospect. The results show that RFID technology is a kind of technology that uses the transmission characteristics of RF signals through space alternating electromagnetic coupling to identify targets and thus realize rapid automatic identification. Since it was developed and used in warfare in the mid-twentieth century, RF identification technology has developed rapidly and developed a variety of applications. Today, with the development of electronic technology and communication technology, RF identification technology already has a wide and irreplaceable role in medicine, military and food safety. It is not difficult to imagine that with more joint applications of new technology, radio frequency-related algorithm improvement, radio frequency tag price reduction, and other conditions, the technology will have a more extensive and profound application in the future.

Polybenzoxazine/organosilicon composites with low dielectric constant and dielectric loss

The evolution of electronic communication technology raises higher requirements for low dielectric constant (low-k) materials. For this, a benzoxazine functional organosilicon (HP-aptes) with dense Si—O—Si crosslinking networks and large sterically hindered tert-butyl groups was prepared by the sol–gel method. Then, a series of polybenzoxazine composites (PPHP) were prepared from intrinsically low dielectric constant bis-functional benzoxazine monomer (P-aptmds) and HP-aptes. The double crosslinking networks of polybenzoxazine and organosilicon further increased the crosslinking density and decreased the dipole density of composites, which endowed the composites with enhanced low-k properties. When the content of HP-aptes is 30% (mass), the crosslinking density was 2.05 × 10−3 mol·cm−3, while that of PP-aptmds was 3.31 × 10−3 mol·cm−3. In addition, the dielectric constant and dielectric loss of PPHP composite at 1 MHz could reach 2.61 and 0.0056, respectively.

Teledermatology in India During the Peri–COVID-19 Outbreak Period: Advantages, Shortcomings, and Challenges

Background Telemedicine is defined as the use of electronic information and communication technologies for health care professionals to provide care to patients. Although available since the pre–COVID-19 era, a huge surge in teledermatology consultations occurred during the COVID-19 outbreak. As access to health care became limited and difficult due to repeated lockdowns, teledermatology helped us provide health care to our patients. Moreover, as dermatology is a visual field, it was even more suitable for teleconsultations. Objective The objectives of this study were to investigate the advantages, shortcomings, and challenges of teledermatology in India during the peri–COVID-19 outbreak period. Methods This was a single-center, retrospective, observational study conducted at a tertiary care hospital in India. Teledermatology consultation data from April 1, 2020, till September 2021 (18 months) were included. All modes, including real-time (RT) video, asynchronous store and forward (SAF), and hybrid, were used to conduct teledermatology consultations. Statistical analyses were performed using SPSS software (IBM Corp). Results During these 18 months, a total of 4280 patients took teledermatology consultations at our center. The mean age of the patients was 34.19 years, with most of them (36.4%) in the age group of 31-40 years. The patient population comprised a mix of urban (55%) and rural (45%) individuals. Overall, 70% of consultations were conducted in the SAF mode; hybrid mode, 16%; and RT video consultations, 14%. Diagnosis was established in 89.1% of the cases, and the most common diagnosis was superficial fungal infection (28%), followed by eczema (16%) and acne (8.6%). Hospital visits were required in the remaining 10.9% of cases for the following reasons: lack of clear pictures and technical errors (5.57%). Additional diagnostic tests were required in 1.3% of cases, physical examination in 1.05% of cases, and 0.39% of patients had life-threatening conditions requiring hospitalization. The advantages of teledermatology include decreased need for hospital visits among 89.1% of patients, which played a very important role in decreasing overcrowding. Also, this helped us provide expert health care to the rural population of India. Owing to shortcomings including the lack of good-quality pictures (4.2%; more so in SAF teleconsultations) and technical errors (1.37%), teledermatology cannot be used to manage life-threatening conditions (0.39%), and, in particular, RT video consultations are more time-consuming (14%). Challenges faced by dermatologists during teledermatology consultations were mainly operational, such as the lack of good internet access leading to interrupted consultations (1.37%), poor quality of pictures (4.2%), and difficulty in extracting history in cases of SAF consultations. Conclusions Teledermatology serves as a triage platform and helps reduce hospital visits. It helps to cater to the rural population, which otherwise has limited access to health care. Some technical challenges are the dependence of teledermatology on pictures and information sent by the patient for establishing the diagnosis. Also, sometimes patients faced difficulty in conveying problems clearly to the doctors. Because of the ease and advantages, several dermatologists have continued to use teledermatology along with the physical consultations in the post–COVID-19 era. With a few advancements, teledermatology will certainly remain a successful and useful model for consultations, more so for catering to the population with the lack of access to specialist services. Conflicts of Interest None declared.

Promoting Residents’ Willingness to Recycle Electronic ICT Waste in China: An Empirical Study Using Conjoint Analysis

Initiated by the Chinese government to mitigate pollution arising from informal recycling, the Internet + Recycling model has been evolving and yielding significant results in China over the past few years. However, due to the large amount of users’ personal information contained in electronic information and communication technology waste, residents are concerned about privacy leaks, leading to a lower willingness to recycle. This study aims to enhance people’s willingness to recycle electronic waste by testing the impacts of various factors through a nationwide survey and analysis. Prior research evaluated e-waste collection attributes separately, thus provoking potential validity concerns. Addressing this concern, our study, based on 184 valid entries, employs conjoint analysis to determine the effects of different attributes on residential recycling choices. Among the considered attributes, recycling trust emerged as paramount, followed by compensation methods, recycling price, and recycling methods. The high-utility attributes included government certification and monitoring, cashback, high prices, and door-to-door service. Transcending the core research aim, our study forecasts market shares for diverse recycling combinations. The results indicate that there is no single dominant strategy, as several combinations are substantially influential. Consequently, businesses are advised to adopt a multi-pronged approach using diverse combinations for optimal results.

Unveiling Post Engagement Rate Using Predictive Analytics Model for Instagram Accounts of Coffee Shops in West Jakarta

During the COVID-19 Pandemic, telemedicine has had a high use rate since the government issued a policy limiting people's movement to reduce transmission. It is because telemedicine can be a way to solve this issue since it can provide and support health care when distance separates the users only using electronic communication technologies. However, through this remote assessment, patients and physicians lose the opportunity to interact in person, which might impact doctor-patient communication. Furthermore, covid-19 cases in Indonesia have shown a downward trend, making the government have no regulation limiting people's movement. Now, people can see their physicians directly for some conditions. Therefore, this research will analyze factors influencing customer intention to consult through telemedicine applications and determine which factors more significantly influence customer intention. This research is conducted through a qualitative approach by semi-structured interviews and a quantitative approach by an online survey of customers who ever experience using telemedicine applications. The researcher uses open coding to analyze the interview result and descriptive statistics and PLS-SEM to analyze the survey result. The author gets seven respondents from interviews and 317 from online surveys. The results indicate that perceived benefit, satisfaction, saving time, saving cost, and performance expectancy influence customer intention to use telemedicine applications continuously. Furthermore, satisfaction and saving costs are the factors that significantly influence customer intention to use telemedicine applications continuously. The finding of this research is expected to give insight into telemedicine applications in Indonesia about making their strategies to enhance their customer intention to use continuously.

Review of Polymer-Based Composites for Electromagnetic Shielding Application.

The rapid advancement of electronic communication technology has greatly aided human productivity and quality of life, but it has also resulted in significant electromagnetic pollution issues. Traditional metals and alloys are often used for electromagnetic interference (EMI) shielding due to their excellent electrical conductivity. However, they have drawbacks such as being heavy, expensive, and having low corrosion resistance, which limits their application in electromagnetic shielding. Therefore, it is crucial to develop novel EMI shielding materials. Polymers, being highly flexible, corrosion-resistant, and possessing high specific strength, are frequently employed in electromagnetic shielding materials. In this review, we firstly introduce the basic theory of electromagnetic shielding. Then, we outline the processing methods and recent developments of polymer-based electromagnetic shielding composites, including uniform-, foam-, layered-, and segregated structures. Lastly, we present the challenges and prospects for the field, aiming to provide direction and inspiration for the study of polymer-based electromagnetic shielding composite materials.
