UNIVERSITY STUDENTS’ ONLINE FOOD DELIVERY (OFD) USAGE INTENTION: INVESTIGATING THE ROLE OF SENSORY MARKETING AND PERCEIVED BENEFITS

Background and Purpose: The increase of mobile phone usage in Malaysia had contributed to the increasing habit of purchasing food through online food delivery (OFD) service platforms. Sensory marketing is a conceptual strategy that helps to appeal to human five senses. It is utilized as promotion made on social media using ads or attractive photos in order to attract customers to order food through the social media platform. This study aims to investigate the role of sensory marketing (sight and touch) and perceived benefits (convenience and product variety) to predict university students’ online food delivery (OFD) usage intention. Methodology: Structural equation modelling is used to accomplish the objectives of this study with the analyses of 400 university students who were surveyed through Google form application. Findings: The findings concluded that both sensory marketing and perceived benefits influence university students’ OFD usage intention. The strongest predictor of OFD usage intention among students is ‘touch’ element representing sensory marketing followed by convenience (perceived benefits), product variety (perceived benefits) and sight (sensory marketing). Contributions: The findings contribute to the relevant literature by improving the knowledge of online food delivery (OFD) usage intention and it may be beneficial to the foodservice providers for continuous improvement of their business. Keywords: Sensory marketing, perceived benefits, online food delivery app. Cite as: Shun Han, K., Abdul Rais, A. R., Tamby Chik, C., & Jaafar, S. N. (2024).

Antecedents of Cloud Gaming Acceptance among Gen Z: Achieving Sustainability in the Digital Gaming Industry

The rapid increase in mobile phone usage among Gen Z online gamers has become more prevalent due to the pandemic. However, the limited processing power of mobile devices has prompted the need for alternative solutions, such as cloud gaming. As an alternative, cloud gaming could be used to lessen the expenses and have the processing power of a high-end computer. Cloud gaming allows users to stream games on various devices, including low-end devices such as smartphones and older computers. This extends the lifecycle of hardware by enabling users to access the latest games without the need for constant hardware upgrades. As a result, e-waste generation decreases, reducing the environmental impact associated with the production and disposal of gaming hardware. This study aimed to determine the acceptance of Gen Z towards cloud gaming as a potential solution in achieving sustainability in the digital gaming industry. The extended technology acceptance model (TAM) was utilized to explore the potential for cloud gaming adoption in the Philippines and the attitudes of Gen Z towards this technology. It was found out that for the average Filipino user, attitude plays the highest significant role in cloud gaming adoption. On the other hand, perceived enjoyment and perceived ease of use were found to have a significant influence on attitude, which in turn, affects the behavioral intention to use cloud gaming among Gen Z. Thus, cloud gaming presents a promising avenue for sustainability in the gaming industry, combining energy efficiency, resource optimization, reduced e-waste, and improved accessibility.

Why Digital Health Literacy Matters in Rural Sub-Saharan Africa: How Bridging the Digital Health Literacy Gap Could Improve Access to Health Services and Social Equality

Why Digital Health Literacy Matters in Rural Sub-Saharan Africa:How Bridging the Digital Health Literacy Gap Could Improve Access to Health Services and Social Equality Ismaila Ouedraogo, Roland Benedikter, Borlli Michel Jonas Some, and Gayo Diallo Digital Health Literacy Matters Around the world, mobile phones have been used for quite some years now to put healthcare systems into interactive action through various mobile health applications. The results regarding efficiency, access, greater social equality, and interconnectivity are proven, and they promise to mitigate economic and educational gaps. All this is increasingly the case in sub-Saharan Africa (SSA), where the technological prerequisites are quickly evolving. About 500 million people in SSA—more than 46 percent of the region's population—were subscribing to mobile services in 2020, and their numbers are forecast to reach 615 million in 2025 (GSMA 2022). In the meantime, coverage works also in the structurally poorest areas. In 2020, 2G mobile network coverage in Burkina Faso was 81 percent for the territory and 92.4 percent for the population (ARCEP 2020). The high penetration rate of mobile phones and the increasing coverage of the mobile network has created a vast variety of opportunities for health provision. Mobile devices can no longer be ignored in practical health delivery and disease prevention workflows. The positive potential of the application of digital health tools is obvious, and it is often said that mobile devices will be a key vehicle on the road to achieving universal health coverage in the Global South. Despite this promise, the deployment of digital health tools in SSA faces many challenges, such as an urban-rural gap, a gender divide, low digital literacy, and a shortage of electricity and interconnectivity [End Page 134] (Holst et al. 2020). Poorly designed, unsustainable, unsafe, and irresponsible digital health products circulate that waste time, energy, and physical and financial resources. Digital health literacy increasingly correlates with digital inclusion—a situation where people can access and use information and communication technologies to take charge of and improve their health. Inversely, digital health technologies become useless when users do not have the skills, connectivity, mutual exchange, or understanding to use them, or do not have access when they need them. Designing digital health solutions that fit with the digital literacy prerequisites and skills of low-qualified users matters crucially in SSA for sustainably sufficient coverage. The ability to find, understand, and use e-health resources is critical for consumers to be able to use current and future health services. Digital health literacy is therefore no longer an option but has become a fundamental requirement in SSA in the design of inclusive solutions. Innovative Mobile Health Initiatives in SSA during the COVID-19 Pandemic The advent of the global COVID-19 pandemic, which began in 2020, has accelerated the pace at which mobile technology is becoming commonplace in people's healthcare. In many countries, healthcare systems rapidly shifted to enabling medical consultations digitally. The increase in mobile phone usage was correlated with an increase in access to information, with phones acting as information relays. Cell phones were used to disseminate pandemic-related information to disadvantaged communities in SSA. Several examples catch the eye. In Burkina Faso, Viamo is a social enterprise that understood this paradigm shift early. It attempted to connect disadvantaged individuals and organizations with appropriate information via mobile devices to enable them to make better decisions (Sandwidi 2020). Through its mobile services, it had played an integral role in bridging the information gap among communities in rural areas long before the advent of the pandemic (UNDP, n.d.). Among other initiatives, it partnered in 2010 with Orange Burkina, a primarily national telecommunication company, to launch a mobile service that allows underserved communities to have free access to information in four of Burkina Faso's most spoken local languages: Mooré, Dioula, Fulfulde, and Gourmanché. Viamo instructions are provided mainly orally, in the same four languages, to include those who cannot read. These approaches, hailed by many customers, have evolved over time. Since 2017, Viamo's platform has covered many themes, including COVID-19 orientation, family planning, health, agriculture, early childhood development, weather forecasts, news, and entertainment. Each theme is usually subdivided...

Real-Time Plant Health Detection Using Deep Convolutional Neural Networks

In the twenty-first century, machine learning is a significant part of daily life for everyone. Today, it is adopted in many different applications, such as object recognition, object classification, and medical purposes. This research aimed to use deep convolutional neural networks for the real-time detection of diseases in plant leaves. Typically, farmers are unaware of diseases on plant leaves and adopt manual disease detection methods. Their production often decreases as the virus spreads. However, due to a lack of essential infrastructure, quick identification needs to be improved in many regions of the world. It is now feasible to diagnose diseases using mobile devices as a result of the increase in mobile phone usage globally and recent advancements in computer vision due to deep learning. To conduct this research, firstly, a dataset was created that contained images of money plant leaves that had been split into two primary categories, specifically (i) healthy and (ii) unhealthy. This research collected thousands of images in a controlled environment and used a public dataset with exact dimensions. The next step was to train a deep model to identify healthy and unhealthy leaves. Our trained YOLOv5 model was applied to determine the spots on the exclusive and public datasets. This research quickly and accurately identified even a small patch of disease with the help of YOLOv5. It captured the entire image in one shot and forecasted adjacent boxes and class certainty. A random dataset image served as the model’s input via a cell phone. This research is beneficial for farmers since it allows them to recognize diseased leaves as soon as they noted and take the necessary precautions to halt the disease’s spread. This research aimed to provide the best hyper-parameters for classifying and detecting the healthy and unhealthy parts of leaves in exclusive and public datasets. Our trained YOLOv5 model achieves 93 % accuracy on a test set.

Smartphone or Smart Behaviour? The role of Phubbing in workplace

Researchers studying behaviour have been attempting to comprehend how pervasive smartphones have become in people’s daily lives for more than a decade. The modern workplace has observed a considerable increase in mobile phone usage for a wide variety of reasons. To this end, prior research reveals that the use of such technology has provided employees with greater workplace flexibility and simultaneously facilitated multiple business processes (Cousins & Robey, 2015). However, it is also commonly recognized that cell phone usage has been a considerable source of counterproductive behaviours that compromise one’s performance at work.

Association of Health Behaviors with Mental Health Problems in More than 7000 Adolescents during COVID-19.

Previous studies show detrimental effects of the COVID-19 pandemic and associated lockdowns on the lives of adolescents. Adolescents have experienced disruption in their daily routines, including changes in health behaviors such as an increased sedentary behavior and increased smartphone usage. The aim of this study was to assess the association of health behaviors with mental health problems in Austrian adolescents during the pandemic. Five cross-sectional surveys (February 2021 to May 2022) were performed during the pandemic assessing physical activity, smartphone usage, depressive symptoms (PHQ-9), anxiety symptoms (GAD-7), sleep quality (ISI-7), and stress (PSS-10). In total, N = 7201 adolescents (age: 14–20 years ((MW±SD): 16.63 ± 1.49 years); 70.2% female, 18.8% migration background) participated. A strong increase in mobile phone usage as well as a decrease in physical activity as compared to pre-pandemic data were observed (p < 0.001). Compared to the lowest smartphone user group (<1 h/d), the adjusted odds ratios (aOR) for all investigated mental health symptoms increased with increasing smartphone usage up to 3.2–6.8 in high-utilizers (>8 h/d). The aORs for depressive, anxiety, insomnia, and stress symptoms decreased in physically active compared to inactive adolescents. Results highlight the need for measures to promote responsible smartphone usage as well as to increase physical activity, so as to promote mental health in adolescence.

Digital Health Apps in the Clinical Care of Inflammatory Bowel Disease: Scoping Review.

BackgroundDigital health is poised to transform health care and redefine personalized health. As Internet and mobile phone usage increases, as technology develops new ways to collect data, and as clinical guidelines change, all areas of medicine face new challenges and opportunities. Inflammatory bowel disease (IBD) is one of many chronic diseases that may benefit from these advances in digital health. This review intends to lay a foundation for clinicians and technologists to understand future directions and opportunities together.ObjectiveThis review covers mobile health apps that have been used in IBD, how they have fit into a clinical care framework, and the challenges that clinicians and technologists face in approaching future opportunities.MethodsWe searched PubMed, Scopus, and ClinicalTrials.gov to identify mobile apps that have been studied and were published in the literature from January 1, 2010, to April 19, 2019. The search terms were (“mobile health” OR “eHealth” OR “digital health” OR “smart phone” OR “mobile app” OR “mobile applications” OR “mHealth” OR “smartphones”) AND (“IBD” OR “Inflammatory bowel disease” OR “Crohn's Disease” (CD) OR “Ulcerative Colitis” (UC) OR “UC” OR “CD”), followed by further analysis of citations from the results. We searched the Apple iTunes app store to identify a limited selection of commercial apps to include for discussion.ResultsA total of 68 articles met the inclusion criteria. A total of 11 digital health apps were identified in the literature and 4 commercial apps were selected to be described in this review. While most apps have some educational component, the majority of apps focus on eliciting patient-reported outcomes related to disease activity, and a few are for treatment management. Significant benefits have been seen in trials relating to education, quality of life, quality of care, treatment adherence, and medication management. No studies have reported a negative impact on any of the above. There are mixed results in terms of effects on office visits and follow-up.ConclusionsWhile studies have shown that digital health can fit into, complement, and improve the standard clinical care of patients with IBD, there is a need for further validation and improvement, from both a clinical and patient perspective. Exploring new research methods, like microrandomized trials, may allow for more implementation of technology and rapid advancement of knowledge. New technologies that can objectively and seamlessly capture remote data, as well as complement the clinical shift from symptom-based to inflammation-based care, will help the clinical and health technology communities to understand the full potential of digital health in the care of IBD and other chronic illnesses.

Design and Usability Evaluation of Social Mobile Diabetes Management System in the Gulf Region.

BackgroundThe prevalence of diabetes in the Gulf States is one of the highest globally. It is estimated that 20% of the population in the region has been diagnosed with diabetes and according to the International Diabetes Federation (IDF), five of the IDF’s “top 10” countries for diabetes prevalence in 2011 and projected for 2030 are in this region. In recent years, there have been an increasing number of clinical studies advocating the use of mobile phone technology for diabetes self-management with improved clinical outcomes. However, there are few studies to date addressing the application of mobile diabetes management in the Gulf region, particularly in the Kingdom of Saudi Arabia (KSA), where there is exponential increase in mobile phone usage and access to social networking.ObjectiveThe objective of this paper is to present the design and development of a new mobile health system for social behavioral change and management tailored for Saudi patients with diabetes called Saudi Arabia Networking for Aiding Diabetes (SANAD). A usability study for the SANAD system is presented to validate the acceptability of using mobile technologies among patients with diabetes in the KSA and the Gulf region.MethodsThe SANAD system was developed using mobile phone technology with diabetes management and social networking modules. For the usability study the Questionnaire for User Interaction Satisfaction was used to evaluate the usability aspect of the SANAD system. A total of 33 users with type 2 diabetes participated in the study.ResultsThe key modules of the SANAD system consist of (1) a mobile diabetes management module; (2) a social networking module; and (3) a cognitive behavioral therapy module for behavioral change issues. The preliminary results of the usability study indicated general acceptance of the patients in using the system with higher usability rating in patients with type 2 diabetes.ConclusionsWe found that the acceptability of the system was high among Saudi patients with diabetes, and ongoing work in this research area is underway to conduct a clinical pilot study in the KSA for patients with type 2 diabetes. The wide deployment of such a system is timely and required in the Gulf region due to the wide use of mobile phones and social networking mediums.

Triple band frequency selective surface design for global system for mobile communication systems

As a result of the enormous increase in mobile phone usage throughout the world, mobile phone base stations are located in almost everywhere nowadays. Many scientific studies have investigated possible health symptoms of mobile systems radiation. The globally recognised organisations have started to release maximum radio-frequency (RF) exposure levels that are regarded as safe. An efficient approach to decrease the RF exposure levels inside the buildings is to transform building walls to a frequency selective surface which filters out global system for mobile communication signals but allows the others, such as radio and television signals. This study proposes a new frequency selective surface element geometry which leads to a minimum 20 dB attenuation in 900, 1800 and 2100 MHz mobile communication bands according to Swiss electromagnetic radiation prevention limit values (NISV, 23 December 1990). High-frequency structure simulator software is used for simulation and design purposes. Due to a given good insight into the resonance characteristics of the FSS structures, it is benefited from the equivalent circuit model in the optimisation process. Achieved results show that the proposed FSS element geometry has a stable frequency response with minimum 20 dB of attenuation levels for transverse-electric (TE) and transverse-magnetic (TM) polarisations when the angle of incident wave is varied from 0° to 60°.

Increase in Specific Absorption Rate (SAR) Of Mobile Phone - A Threat to Human

Drastic increase of mobile phone usage increases the concern about the effect of electromagnetic radiation on human brain. During the last decade, several researches were conducted in this area and reported the effect of radiation on brain. Unfortunately most of these findings cannot be reproduced. Findings of a number of studies ascertain that, there is no clear evidence to link the relationship between the adverse effects and mobile phone usage. The reason of the changes observed in human body due to radiation and the causes that leads to non reproducibility of these results has to be investigated. In [1] it is reported that, adverse effect of radiation occurs in cellular level if SAR is much higher. So we tried to study the change in SAR using FDTD simulation by increasing the power of excitation. Frequency range is selected as the specified range of frequency permissible for mobile phone communication. The value of SAR obtained for the above specified range of frequency is found within the permissible limit insisted by ICNIRP/IEEE. But on increasing the magnitude of power of excitation, the magnitude of SAR also increased. It can be concluded that, if the transmitting power is not within the permissible limit, there is a possibility to increase the values of SAR, which may cause health hazards.

Factors Affecting Customers’ Buying Decisions of Mobile Phone : A Study on Khulna City, Bangladesh

This study has put efforts to uncover the underlying factors those affect customers in choosing mobile phone. Data were collected from those people live in Khulna city maintaining equal ratios of various groups like male, female, businessmen, employees, students and others (mostly housewives). To select desired respondents, convenient sampling method was used. A structured questionnaire designed based on previous study with five point Likert scale was used to interview respondents. Factor analysis was applied to extract the underlying factors affect mobile phone purchasing decision. The results show that the most important factor is physical attributes. Some other factors are pricing, charging and operating facilities, size and weight, friends’ and colleagues’ recommendations, neighbors’ recommendations and advertising.

Comparison of specific absorption rate induced in brain tissues of a child and an adult using mobile phone

The steady increase of mobile phone usage, especially mobile phones by children, has led to a rising concern about the possible adverse health effects of radio frequency electromagnetic field exposure. The objective of this work is to study whether there is a larger radio frequency energy absorption in the brain of a child compared to that of an adult. For this reason, three high-resolution models, two child head models (6 - and 11-year old) and one adult head model (34-year old) have been used in the study. A finite-difference time-domain method was employed to calculate the specific absorption rate (SAR) in the models from exposure to a generic handset at 1750 MHz. The results show that the SAR distributions in the human brain are age-dependent, and there is a deeper penetration of the absorbed SAR in the child’s brain. The induced SAR can be significantly higher in subregions of the child’s brain. In all of the examined cases, the SAR values in the brains of a child and an adult are well below the IEEE safety standard.

Cognitive Performance Measures in Bioelectromagnetic Research - Critical Evaluation and Recommendations

BackgroundThe steady increase of mobile phone usage has led to a rising concern about possible adverse health effects of radio frequency electromagnetic field (RF EMF) exposure at intensities even below the existing safety limits. Accumulating evidence suggests that pulse-modulated RF EMF may alter brain physiology. Yet, whereas effects on the human electroencephalogram in waking and sleep have repeatedly been shown in recent years, results on cognitive performance are inconsistent.MethodsThis review compares 41 provocation studies regarding the effects of RF EMF exposure similar to mobile telephones on cognitive performance measures in humans. The studies were identified via systematic searches of the databases Pub Med and ISI Web of Science and were published in peer-reviewed journals between 1998 and the end of 2009.ResultsBased on a critical discussion within the scope of methodological standards it is concluded that state-of-the-art-methods in bio-electromagnetic research on RF EMF effects and cognition have neither been specified nor fully implemented over the last 10-11 years. The lack of a validated tool, which reliably assesses changes in cognitive performance caused by RF EMF exposure, may contribute to the current inconsistencies in outcomes. The high variety of findings may also be due to methodological issues such as differences in sample size and the composition of study groups, experimental design, exposure setup as well as the exposure conditions, and emphasizes the need for a standardized protocol in bioelectromagnetic research.ConclusionsAt present, no underlying biological mechanism has been identified which mediates the effects on brain functioning as observed in electroencephalographic (EEG) studies. A future aim must be to identify this mechanism as well as a reliable exposure protocol in order to gain more insights into possible behavioral and related health consequences of high-frequency EMF exposure.

MHealth: Evidence and Best Practices

Due to the rapid increase in mobile phone usage and service coverage, there is a developing interest on the potential use of mobile communication to improve health care services even in remote and less resourced settings. Although still at its early stages it has already begun to transform health delivery even in the developing world demonstrating sustainable benefits in increased access to health-related information, improved ability to diagnose and track diseases and expanded access to continuing medical education and training for health workers. With number of projects implemented and proven benefits, all trends indicate that investment will continue and m-Health projects will be an important component of the health care sector in future. According to the m-Health for Development report, to accelerate this momentum and fully unleash the potential of m-Health applications, dynamic multi - sector collaboration between groups as diverse as governments, multilateral organizations, and the private sector is needed.

Simulation to track 3D location in GSM through NS2 and real life

In recent times the cost of mobile communication has dropped significantly leading to a dramatic increase in mobile phone usage. The widespread usage has led mobiles to emerge as a strong alternative for other applications one of which is tracking. This has enabled law-enforcing agencies to detect overspeeding vehicles and organizations to keep track its employees. The 3 major ways of tracking being employed presently are (a) via GPS [1] (b) signal attenuation property of a packet [3] and (c) using GSM Network [2]. The initial cost of GPS is very high resulting in low usage whereas (b) needs a very high precision measuring device. The paper presents a GSM-based tracking technique which eliminates the above mentioned overheads, implements it in NS2 and shows the limitations of the real life simulation. An accuracy of 97% was achieved during NS2 simulation which is comparable to the above mentioned alternate methods of tracking.

Telecommunications Revolution: Implications on Criminality and Family Crisis in the South-South States of Nigeria

In recent times telecommunications revolution especially the use of mobile phones is transforming the Nigerian society in many ways. The socio-economic and cultural impacts are enormous. As the spectrum of mobile phone usage increases, opinion differs among users on the impact of this revolution in Nigerian. This paper therefore set to investigate the impact of telecommunications revolution especially text based messages on criminality and family crisis in Nigeria. In doing this, the study elicited data through questionnaire from 7200 respondents who were randomly and purposively selected. Analysis of this data revealed that, most Nigerians were duped through text messages, while significant numbers of marriages are in crisis due to spouse assess to text messages that suggest suspicious of infidelity among partners. We recommended among others that Nigerian should scrutinize text messages before reacting to its content and that proper documentation of Sims pack users is necessary.
