Mobile application: awareness of the population on the environmental impact

Nowadays, pollution keeps increasing due to social, political, economic, cultural, and environmental factors. Environmental awareness is close to zero because people prioritize personal activities. In that sense, the objective of this investigation is to raise environmental awareness in the population regarding the impact of pollution and support this through a mobile application (APP) that helps reduce pollution. The methodology used was the cascade, and through its phases, it was developed the prototype design of the mobile APP. The results obtained from this hybrid research were through a survey using ATLAS.ti 22; it concluded that environmental awareness begins at home and is taught by the parents, also it should be promoted from elementary school to high school and even in college. Moreover, in a survey, the users stated by 89% that the use of this mobile APP can help reduce the environmental impact. Also, in the validation through expert judgment, all the attributes were accepted with an average of 81%, that of functionality was the lowest, and the highest was that of consistency and integration with 83%. Finally, environmental education should be a priority policy in any country, as this will benefit its population.

 Respondents highly appreciated the automatic calorie count, macronutrient settings, daily and weekly nutrition and activity tracking system, as well as the application's charts and their informativeness. This indicates the effectiveness of the developed functionality and the convenience of using the application. Two directions of proposed improvements that garnered the most interest among respondents were identified, such as «Ability to add recipes, photos of dishes, diet planning, nutritional recommendations, diet templates» and «User instructions, manuals, pop-up tips».
 Respondents noted that there is a certain reserve for improvements in the convenience and understandability of the application's interface, the completeness, diversity, and quality of functions, and the review of nutrition and activities for the week in the form of a list.

Unveiling the relationship between social anxiety, loneliness, motivations, and problematic smartphone use: A network approach

BackgroundPrevious studies suggested social anxiety as an essential risk factor for problematic smartphone use, but the complex interactions and the most influential components affecting this relationship remain unclear. This study capitalizes on network analysis to identify the central factors and possible mediating paths among social anxiety, loneliness, five types of motivation, and problematic smartphone use. Material and methodsEmploying 549 emerging adults, we obtained a stable network of the above variables. The central components and the stability of this network were also identified. ResultsWithin this network, the edge linking withdrawal behavior and use of application (APP) exhibits the most robust edge intensity. The central components include social comfort, use of APP, withdrawal behavior, and companionship while the bridge central nodes include social anxiety and escapism motivation. The direct link between social anxiety and PSU revealed only fragile edges with both withdrawal behavior and use of APP. Considering the possible mediating pathways, three pathways were observed in our network. Loneliness and escapism mediated the relationship between social anxiety and social comfort. Moreover, another mediating way was from social anxiety, loneliness, social interaction motivation, and escapism motivation to social comfort. DiscussionBased on the above identification of related components and pathways, future researchers could intervene against problematic smartphone usage in this socially anxious population.

Challenges in Acceptance of Smartphone-Based Assistive Technologies: Extending the UTAUT Model for People With Visual Impairments

Introduction: Despite the plethora of sensor-based assistive technology solutions, there is still no widespread acceptance and adoption by people who are blind or have low vision (i.e., visually impaired). Many reasons prevent reducing abandonment levels with a prominent one being a lack of focus on the dimension of training, which, from our standpoint, is integral to the acceptance of assistive technologies. To prove the importance of training, we extend and validate a new version of the Unified Theory of Acceptance and Use of Technology (UTAUT) model incorporating training as a factor. Methods: Closed- and open-ended questionnaires were given online and offline to 231 participants with visual impairments after conducting training sessions with an application for outdoor navigation by people with visual impairments developed by our research team. To assess the UTAUT extension exploratory factor analysis, confirmatory factor analysis, and structural equation model were employed to explore the relationships between the factors. A usability and user experience qualitative analysis supplemented the previous. Results: We uncovered that no factor besides performance expectancy (standardized regression weight = 0.264, p < .001) and training (standardized regression weight = 0.538, p < .001) significantly predict behavioral intention. Furthermore, the analysis demonstrated a significant interaction ( p < .007) strengthening the positive relationship between training and behavioral intention (standardized regression weight = 0.142). The qualitative analysis showed an overall positive evaluation highlighting the application's usefulness and dependability. Discussion: An application's adoption increases if individuals who are visually impaired are properly trained and acquainted with the features in real-life scenarios and recognize the application's utility for their daily lives. Implications for Practitioners: Training plays an important role in technology acceptance. It can be leveraged to make solutions more appealing to people who are visually impaired.

The Application of Developed Delone & McLean Method to Analyze The Success and Effectiveness of Alfagift Application Among Big Cities' Users in Indonesia

This research aims to find out how successful application use is and what factors influence the successful use of online shopping applications. This research uses quantitative methods. Users of online shopping applications in Jabodetabek were given a questionnaire via Google Form as part of the data collection method used in this study. Users of online shopping apps made up the study's population. Purposive sampling was the method used to choose the study's sample. In this study, a sample of one hundred respondents was used. The two types of data analysis are statistical analysis and demographic analysis. The results of the conducted research support the notion that the presence of online shopping applications is beneficial, and that user perceptions play a significant role in the success of an application's use. Respondents can shop online with convenience and utility thanks to the services offered by online shopping applications. User satisfaction with net benefits is the most significant factor, according to the path coefficient and t-test values. This indicates that consumers are happy with the online shopping app and are inclined to accept the advantages it provides. Consumers believe that an element that can raise the net benefit value of online shopping applications is user satisfaction. According to the path coefficient and t-test values, service quality is the factor that has the least impact on users' perceptions of its usefulness. This indicates that consumers believe the usefulness value they perceive from online shopping applications cannot be enhanced by the quality of those services. So, improvements need to be made so that the success of using the application increases.

Understanding the Role of Service Quality of Government APPs in Continuance Intention: An Expectation–Confirmation Perspective

Given the huge investment made in developing government applications (APPs), it is essential for them to achieve the levels of performance needed to ensure service quality and meet public needs. Although public loyalty is crucial to the success of government APPs, few studies have analyzed the characteristics of service quality or the continuous use of government APPs and their associations. The present study has developed a theoretical model to show how government APPs service quality promotes continuance intention. A questionnaire survey of 388 government APP-users in China and a structural equation model have been used to verify this theoretical model. The empirical results show that overall service quality has an indirect positive impact on government APPs users’ continuance intention through expectation confirmation, perceived usefulness, and user satisfaction. This study enriches our understanding of service quality and government APPs continuance intention, while also exploring government APPs development, design, and promotion.

Privacy nutrition labels, App Store and the GDPR: Unintended consequences?

In an effort to increase the transparency of personal data processing carried out via applications listed on their mobile store, Apple recently announced the launch of privacy nutrition labels (PNLs). Aimed at informing users about an application's use of data, these card-like labels are prominently visible on each application's App Store page. This paper explores whether such disclosures made via PNLs can help data controllers fulfil their duty of transparency under the EU General Data Protection Regulation (GDPR). It establishes that the PNLs, in their current, highly standardised fashion, cannot convey the mandatory obligations required by the GDPR. Added to this, they cannot adequately supplement existing privacy policies, either — as they neither serve an adequate role as a ‘first layer’ of a privacy notice, nor help communicate information more efficiently. However, the paper finds that the PNLs might serve another purpose: enhancing data controllers' internal compliance routines. PNLs, even with their current limitations, can bring tangible improvements to cross-functional communication, third-party sharing awareness, records of processing accuracy, adherence to the data protection principles and adequate resource assignment. The overall conclusion of the paper, counterintuitive as it might appear, is that PNLs should be viewed as an organisational measure-enhancing mechanism rather than a transparency tool.

Effects of mobile APP for immunization on vaccination compliance of migrant children in southwest China: A community trial study

ABSTRACT With the advancement of the “internet plus” action plan in China, the electronic information system and the mobile phone applications (APPs) are widely used in the management of expanding national program of immunization (EPI). To estimate the use of childhood vaccination APP to improve migrants’ vaccination knowledge, attitude and practice (KAP), a community trial toward migrant children was carried out in Chongqing, China. Migrant children were divided into two groups, one group was provided with health education and vaccination reminders in manual way and the other group was provided with online health education and vaccination reminders by mobile APP. After seven-month interventions, a total of 196 guardians of migrant children aged 2 months to 2 y participated in the questionnaire survey. There were significant differences between two groups in the awareness of vaccine policy, disposal of adverse reaction and attitude toward vaccination. Few significant differences in vaccination coverage of children ≤12 months between two groups, except 2ndbOPV and 2ndMenA. The timely vaccination rate of children >6 months in the APP group ranged from 37.5% to 68.2%, that was from 0% to 30.5% in the non-APP group (P < .05). Most migrant children above 6 months had vaccination within a month after due day in the APP group, while that was at least 3 months after due day in the non-APP group. The vaccination APP greatly improved migrants’ KAP on vaccination. Continuous and systematic intervention by vaccination APP would play a more critical role in the vaccination behaviors of older migrant children.

Role of Training for Successful Use of Audit Tool Software

This study examined the antecedent variables of using audit software tools to assist the auditor in completing tasks. Data were collected by distributing 303 questionnaires to auditors in Indonesia, while the technology acceptance model was used as the basis for constructing the required hypothesis. The returned questionnaires were tested for validity and reliability at the trial stage and after data collection. The data collected was analyzed using SmartPLS Ver.3.2.9 software, a structural equation modeling approach. The result showed that thirteen hypotheses were tested, of which four were rejected and nine were accepted. Furthermore, auditors' acceptance of new information systems depends on anxiety level, ease of use, and understanding of the application's usefulness. Hence, parties interested in using the audit software must conduct intensive introduction and training, which are critical to its successful implementation. Training reduces anxiety and increases computer intellectual capital and ease of use, which are important for the possible acceptance of a new system. Appropriate training reduces auditors' anxiety about using new applications and increases their intellectual capital. It will reduce paradox in conditions where investment in information systems is expensive but has low returns. The three-stage Sobel test concludes anxiety and intellectual capital are intervening variable, therefore, implementing the application in a hurry will reduce its actual usage.

Threat modeling in application security planning citizen service complaints

The mobile-based service complaint application is one way to implement good governance today. Public facilitated to make complaints without going through a complicated process. Security aspects must be considered to protect user privacy. The security design must be considered so that no one is harmed by the application's users damaged in the application's use. This study used threat modeling during the planning stage of developing a citizen service complaint application to obtain information about vulnerabilities. The researcher uses the threat modeling process that the open web application security project (OWASP) organization has formulated as a framework. The researchers took steps to describe application information, determine and rank threats, countermeasures, and mitigation. In the final stage, the spoofing, tampering, repudiation, information disclosure, denial of service and elevation of privilege (STRIDE) threat modeling methodology is used to analyze and assess mitigation actions against threats in the application. The researcher gets a defense strategy to reduce the danger based on the threat analysis results. Threat modeling in the early phase software development life cycle process is constructive in ensuring that software is developed with adequate security based on threat mitigation from the beginning.

Profile of adults users of smartphone applications for monitoring the level of physical activity and associated factors: A cross-sectional study.

BackgroundThere are currently more than 200 million smartphones in Brazil. The potential of mobile technologies for favorable changes in health behavior such as physical activity has been previously described in the literature. Results of surveys in developed countries indicate that applications (APPs) are developed for people who are better educated, younger, and with higher incomes compared to non-users. However, the profile of users in developing countries like Brazil is not well-known. Understanding the profile of APP users might ease the development turned to physically inactive people and those at higher cardiovascular risk. Furthermore, the physiological and functional factors associated with the use of such APP are unknown.ObjectivesTo characterize the profile of APP users to monitor the physical activity level (PAL) and assess the demographic, socioeconomic, clinical, physiological, and functional characteristics associated with the use of smartphone APPs to monitor physical activity in Brazilian adults.MethodsWe assessed 176 asymptomatic men and 178 women (43 ± 12 years; 27 ± 5 kg/m2). We initially asked participants about their current use of a smartphone APP containing PAL monitoring functionality, such as exercise session logs and/or step counts. In a cross-sectional design, we investigated schooling, socioeconomic status (Critério Brasil), and classic self-reported cardiovascular risk factors. We evaluated several physiological and functional variables such as maximum O2 consumption on a treadmill (VO2 max), blood pressure, body composition (bioelectrical impedance), handgrip strength, and isokinetic muscle strength of the dominant lower limb. Participants used a triaxial accelerometer for 7 days to quantify daily physical activity. We also assessed health-related quality of life (WHOQOL BREF), perceived stress (PSS14 Scale), and the built environment (NEWS Scale). We compared continuous variables using the Student's t-test and categorical variables using the χ2 test, between APP users and non-users. After univariate analysis, we included the main variables associated with the use of APP in a multiple logistic regression model.ResultsOne hundred and two participants (28.3%), unrelated to gender, reported using a smartphone APP for physical activity at the time of assessment. Except for perceived stress and the built environment that were not associated with the use of APP, users of APP were younger and had higher education, lower cardiovascular risk, better socioeconomic status, a better quality of life, better cardiorespiratory function, better body composition, greater physical fitness and more moderate to vigorous physical activity in daily life. The results of the multiple logistic regression showed that age, hypertension, VO2 max, socioeconomic status (Critério Brasil), and quality of life (WHOQOL BREF total score) were the variables most significantly associated with the use of the APP.ConclusionsOur results indicate that smartphone APPs to monitor physical activity are developed for younger adults with better socioeconomic status, lower cardiovascular risk, higher quality of life, and greater cardiorespiratory fitness. Greater efforts are needed to develop a science-based APP for people who most need this technology, enabling greater potential to prevent undesirable health outcomes in asymptomatic adults.

Adolescent Addiction to Short Video Applications in the Mobile Internet Era.

The adolescent addiction to short video applications is becoming increasingly prominent, which has brought great challenges to the physical and mental health and daily life of the adolescents. This manuscript conducts an empirical study on the contributing factors of the adolescent addiction to short video applications based on the user generated content (UGC). In our study, 96 participants aged 15–25 were surveyed by questionnaire, and then cross-analysis of individual factors and SEM analysis of UGC content factors were carried out. Through the analysis of individual factors of the adolescent addiction from the perspective of gender, age, and family environment, this study reveals that male users are more addicted to the use of applications (APP), and such addiction varies with age, and prolonged family members’ use of short video APP can also exacerbate the adolescent addiction degree. Furthermore, through verification of the theoretical model, it indicates that UGC perception and the degree of boredom in daily life have a significant positive effect on the level of addiction to short video applications, and the degree of boredom in daily life plays a significant mediating role between them. Based on the research on the influences of UGC on the adolescent immersive experience, this study proposes a mechanism of the adolescent addiction to the use of short video applications in the mobile Internet age to provide a better service guarantee for the adolescents.

An Effective Communication Strategy Based on Trust: the Key Element to Adopting a Covid-19 Contact Tracking Application

To cope with the COVID-19 pandemic, contact tracing applications have been proposed to limit positive cases and reinforce other measures, especially before the appearance of vaccines. A high rate of adoption by citizens is required. This study investigates the impact of trust on the adoption of tracking applications. A survey was administered in Morocco, where the authorities proposed the «Wiqaytna» application. Structural Equation Modeling was used to test the hypotheses of the proposed model. The model explains 53% of the variance of the “intention to use” and 40.8% of the “actual use” of the application. The model was based on the UTAUT technology acceptance model and the GAM model of e-gov service acceptance. Our main objective was to study the impact of trust in the decision of Moroccans to use this type of application. Technology trust, government trust and social influence were important determinants of intention to use. The proposed model also shows that perceived awareness is an important antecedent of trust constructs. The impact of «perceived awareness» on the trust constructs (technology and government) is stronger than the social influence on the latter. Moreover, our model shows that «Perceived Awareness» has a more significant impact on «technology trust» than on «government trust». Due to their lack of interest (in seeking information) and attention (communications on the application), citizens lack information about the application's usefulness and the security of users' data. Even those who have had contact with the information they are looking for cannot often verify its credibility (e.g. the source code of the «Wiqaytna» application was available on Github). Therefore, cognitive and individual factors give way to social influence, and the intention to use becomes dependent on the norms and suggestions of influential people in the individual's environment. The latter construct is complex and has multiple determinants. Several factors act on the construction of trust in the authorities' quality of public services. Finally, the strongest relationship in the model is the effect of intention to use on using the Wiqaytna application. Based on these findings, suggestions are made for policymakers. First, a significant effort must be made to improve citizens' awareness of the importance of such an application for the control of the pandemic, even after the launch of the vaccination campaign and the application of social distancing measures. Indeed, a few posters here and there and a few commercials are not enough. An effective communication strategy must be built to explain to citizens the critical role these applications can play and reduce fears about citizens' privacy to increase the adoption rate of these applications. Secondly, the role of social influence is critical in adopting applications. This must be considered in communication campaigns and the involvement of opinion leaders and influencers to be more effective and increase the intention to use them.

Abstract 12491: Use of a Self-Care Mobile Phone Application Can Improve Patient Education and Medication Adherence in Patients With Acute Decompensated Heart Failure

Introduction: The use of digital health technologies using mobile phone health applications has increased over the last few years. We developed a mobile phone application (APP) (Aintree Heart Failure Passport APP) for heart failure (HF) patient self-education and improved medication adherence. The APP consisted of a Traffic Light System for education self-care advice, prompt for medications, reminder of appointments, educational videos as well as a mood check questionnaire. Methods: This was a pilot feasibility study in a British university hospital conducted in 2019 and 2020. We assessed self-care behaviour following the use of the Aintree Heart Failure Passport Mobile APP in a cohort of patients with acute decompensated HF. We employed the use of European Heart Failure Self-care Behaviour scale (EHFSBs), medication adherence using the Medication Adherence Report Scale (MARS-5) at 2 weeks and compared 30-day HF readmissions with annual hospital HF data. Descriptive statistics were represented as continuous variables as means with standard deviations. Categorical variables were represented with percentages and analysed using Chi-squared test. Results: 102 patients with acute decompensated HF were recruited to this pilot feasibility study. 57% were men and mean age 56 years±5.1. 55% patients had HF with reduced ejection fraction (HFrEF), 34% had HF with preserved EF (HFpEF) and 11% had HF with mid-range EF. Mean EHFSBs was 19.7±6.1and mean MARS-5 score was 23.5±1. 10/102 (10%) patients were re-hospitalised with HF compared to the annual hospital HF rehospitalisation incidence which was 19% (95/393); p=0.04. Conclusions: Results from our pilot feasibility study suggest that use of a HF self care mobile phone APP (Aintree Heart Failure Passport App) in patients with acute decompensated HF, leads to high quality self care behaviour, high levels of medication adherence and lower levels of 30-day HF re-hospitalisation. These results will need to be validated in a randomised controlled trial.

Smart-phone Based Geofencing: A Novel Approach to Monitoring Clinical Work Hours in Surgery Residency

The Accreditation Council for Graduate Medical Education specifies strict requirements for clinical work hours during residency training, with serious consequences for violations. Self-reporting of work hours by trainees can be inaccurate due to recall bias, giving program directors limited data to influence change. We aimed to assess the impact of a smart-phone based geofencing application on submission rates for work hours and reported violations in a general surgery residency program at a university-based medical center. We also examined resident perceptions surrounding implementation and use of the application. We compared clinical work hours submitted and violations reported during the pilot period (October-November 2019) with the months prior to the launch of the application (July-August 2019). PGY1 and PGY2 residents were eligible to use the application during and after this pilot period. Semi-structured interviews were used to assess resident perceptions. A retrospective review was conducted to compare reporting during the same time period from the prior academic year (2018-2019) for historical reference. Paired t-tests were used to analyze the data. Twenty-six residents (15 PGY1, 11 PGY2) were eligible for the intervention and 23 residents (88%) used the application. The mean number of violations reported decreased significantly during the pilot period compared with the months prior to the intervention (4.5 vs. 11, p = 0.04). The total rate of submissions was not significantly different after the intervention (85% vs. 82%, p = 0.42). The PGY1 mean submission rate decreased during the pilot period (91%-75%, p = 0.21) while the PGY2 submission rate increased (77%-91%, p = 0.07). Compared with historical data, there was an increase in overall total submission rates between academic years 2018/2019 and 2019/2020 (74% vs. 79%, p = 0.047) and an associated decrease in the mean number of monthly violations (14 vs. 6.25, p = 0.004). Thirteen (50%) residents (8 PGY1, 5 PGY2) volunteered for semi-structured interviews. Most participants found the application useful for recording and reporting clinical work hours. They noted an ease in the administrative burden as well as more accurate reporting associated with automated logging. Use of the application was not perceived to limit engagement with patient care; however, there were privacy concerns and some technical barriers were identified. The messaging regarding the application's use was identified as critical for implementation. The "real-time" data provided by a geofencing application in our program helped to reduce the number of work-hour violations reported and did not diminish resident engagement with patient care. Decreasing the administrative burden of recording work hours coupled with improving transparency and accuracy of submissions may be important mechanisms.

Experiences of Health Care Providers Using a Mobile Medical Photography Application.

To understand the ways in which providers use a mobile photography application integrated with the electronic health record (EHR) to facilitate clinical care, and the process outcomes that result from the application's use. An e-mail survey was sent on November 13, 2017, to 1,463 health care providers at Mayo Clinic who had used an internally developed, EHR-integrated medical photography application. The survey was completed by 712 (49%) providers. Providers reported using the application on approximately 1 in 7 days spent in clinical practice. Median provider satisfaction with the use of the application (0-100 scale; higher numbers indicate favorable response) was 94 (interquartile range [IQR]: 74-100). Although the use for store-and-forward telemedicine was reported (22% often or frequently used the application to send photographs to a specialist for advice), the most common use was for clinical documentation (65% often or frequently used the application to supplement text-based notes with photographs, and 71% often or frequently used the application to take photographs for reference by a colleague who may see the patient in the future). Of the health care providers, 36% indicated that the application's use often or frequently expedited treatment. Health care providers reported using a mobile point-of-care medical photography application regularly in clinical practice and were generally satisfied with the application. Point-of-care medical photography using a secure mobile, EHR-integrated application has potential to become a new standard of care for clinical documentation and may facilitate continuity across the continuum of care with multiple providers who see a patient.
