Algorithm Improvement for Mobile Event Detection with Intelligent Tunnel Robots

Mobile inspections conducted by intelligent tunnel robots are instrumental in broadening the inspection reach, economizing on inspection expenditures, and augmenting the operational efficiency of inspections. Despite differences from fixed surveillance, mobile-captured traffic videos have complex backgrounds and device conditions that interfere with accurate traffic event identification, warranting more research. This paper proposes an improved algorithm based on YOLOv9 and DeepSORT for intelligent event detection in an edge computing mobile device using an intelligent tunnel robot. The enhancements comprise the integration of the Temporal Shift Module to boost temporal feature recognition and the establishment of logical rules for identifying diverse traffic incidents in mobile video imagery. Experimental results show that our fused algorithm achieves a 93.25% accuracy rate, an improvement of 1.75% over the baseline. The algorithm is also applicable to inspection vehicles, drones, and autonomous vehicles, effectively enhancing the detection of traffic events and improving traffic safety.

Maximizing energy efficiency in HetNets through centralized and distributed sleep strategies under QoS constraint

This research addresses the critical need to optimize the Energy Efficiency (EE) for Ultra-Dense HetNets amid the ever-increasing demands for high-speed data networks. The rapid increase in high-speed devices highlights the urgent necessity for a transformative change in upcoming 5G cellular networks. According to Ericsson's 2022 report, mobile data traffic volume is expected to double by 2027, with mobile video traffic anticipated to rise by nearly 30% each year. In response to these challenges, researchers have identified essential technologies that facilitate 5G networks, including massive Multiple-input-Multiple-output (m-MIMO) systems and HetNets. Although both promise enhanced coverage and throughput, HetNets emerges as a cost-effective solution, surpassing m-MIMO in implementation cost and coverage. However, achieving maximum EE in HetNets necessitates careful consideration of various constraints, including delay, coverage probability, and Signal-to-Interference-plus-Noise Ratio (SINR) thresholds. This research marks a significant milestone in adopting the Distributed Dynamic Opportunistic Sleep Strategy (D-DOSS) approach. The D-DOSS method organizes small clusters throughout the network and evaluates key Quality of Service (QoS) parameters including Energy Utilization Efficiency (EUE), Coverage Probability, Data Throughput, and Success Probability using Monte Carlo simulations. This research analyzes Distributed Sleep (DS) and Centralized Schemes (CS) concerning given QoS parameters. While DS methodologies often exhibit performance trade-offs compared to CS, they provide significant advantages in terms of ease of implementation and management. CS, though representing the most commonly used method in ultra-dense HetNets involves high computational costs that complicate its management. By integrating the D-DOSS and addressing various constraints, this research not only advances HetNet technologies but also makes a significant contribution to optimizing EE while preserving network performance and QoS. The innovative D-DOSS approach offers a promising solution to the challenges of energy efficiency in wireless communication networks and paves the way for future advancements in HetNet deployments. The results and analysis show that D-DOSS effectively addresses the limitations of DS and outperforms existing CS techniques.

Slow-Paced Breathing Intervention in Healthcare Workers Affected by Long COVID: Effects on Systemic and Dysfunctional Breathing Symptoms, Manual Dexterity and HRV.

Many COVID-19 survivors still experience long-term effects of an acute infection, most often characterised by neurological, cognitive and psychiatric sequelae. The treatment of this condition is challenging, and many hypotheses have been proposed. Non-invasive vagus nerve stimulation using slow-paced breathing (SPB) could stimulate both central nervous system areas and parasympathetic autonomic pathways, leading to neuromodulation and a reduction in inflammation. The aim of the present study was to evaluate physical, cognitive, emotional symptoms, executive functions and autonomic cardiac modulation after one month of at-home slow breathing intervention. 6655 healthcare workers (HCWs) were contacted via a company email in November 2022, of which N = 58 HCWs were enrolled as long COVID (cases) and N = 53 HCWs as controls. A baseline comparison of the two groups was performed. Subsequently each case was instructed on how to perform a resonant SPB using visual heart rate variability (HRV) biofeedback. They were then given a mobile video tutorial breathing protocol and asked to perform it three times a day (morning, early afternoon and before sleep). N = 33 cases completed the FU. At T0 and T1, each subject underwent COVID-related, psychosomatic and dysfunctional breathing questionnaires coupled with heart rate variability and manual dexterity assessments. After one month of home intervention, an overall improvement in long-COVID symptoms was observed: confusion/cognitive impairment, chest pain, asthenia, headache and dizziness decreased significantly, while only a small increase in manual dexterity was found, and no relevant changes in cardiac parasympathetic modulation were observed.

What is the learning model of physical education in the digital era? Literature review of various studies

The digital age has changed the landscape of physical education (PE), with technology playing an important role in the learning process. This article reviews various studies on the use of technology in physical education to understand the trends, benefits, and challenges in implementing digital learning models. The search in this study used the Harzing Publish or Perish application. The search was initiated using the Scopus database with keywords ("learning model" AND "physical education" OR "sports education" AND "digital era"). Initially, 12.654 publications were identified through the database search (Scopus: 2,831 articles). After following exclusion criteria, only 10 articles remained. The search was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review showed that technologies such as mobile apps, e-learning, virtual reality, digital media, and video games can improve student motivation, engagement, and understanding. However, challenges such as infrastructure limitations, user readiness, and potential reduction of physical aspects in physical learning need to be considered. Therefore, a balanced approach between the use of technology and physical activity is needed, as well as adequate support to maximize the benefits of technology in physical education. Further research is recommended to explore more effective strategies in integrating technology into physical education learning across different contexts. Although there are many studies on adolescent girls' lack of engagement in Physical Education (PE) in the literature, most only investigate the root causes, while few take initiatives to address the inherent problems. Keywords: learning model, physical education, digital era, technological advancement

Little grinder, big concern - a questionnaire survey

Background: Bruxism in paediatric dentistry refers to the habitual grinding or clenching of teeth in children. This condition can manifest during the day or night and may have various underlying causes. Bruxism has multifactorial etiology including disturbed sleep cycle and excessive gadget use in children. Present study aimed to evaluate the knowledge and awareness of parents about bruxism in children who visited the department. Bruxism is a common concern in paediatric dentistry, presenting challenges for dental professionals and parents alike in managing and addressing its effects on a child's oral health. Methods: The study was conducted among the parents visiting the Department with their children for the treatment. A self-administered questionnaire about knowledge and awareness regarding bruxism habit, sleep cycle, and gadget use in children was made. It was shared with parents using E-methods. Data was collected and statistical analysis was done. Results: In this study, parents stated that 74.1% of children grind their teeth, and 63% of children did so while using the device. Children most frequently utilized mobile devices (51.9%), then TV (13%), electronic toys and video games (11.10%), laptops/PCs and tablets (6.50%). Before falling asleep, 81.50% of the kids used their gadgets, and after using them, 60.20% of the kids reported having trouble sleeping. Conclusions: According to this study, children who clench their teeth have disrupted sleep, and clenching of teeth is more common in children who experience stress as a result of prolonged use of gadgets. Thus, a significant relationship was seen between children's use of gadgets, sleep disruption, and bruxism.

Promoting HPV vaccination: effectiveness of mobile short videos for shaping attitudes and influencing behaviors

The explosive growth and attractive features of mobile short videos (MSVs) have made it become an effective tool for disseminating health-related information. This study aims to examine the potential informational and technical factors of MSVs, which contribute to the persuasive effects on people’s decision-making process toward HPV vaccination. An experiment with a 2 (information quality: high vs. low) × 2 (source credibility: high vs. low) × 2 (media richness: high vs. low) between-subject factorial design was conducted among 248 Chinese female students. Findings revealed significant persuasive impacts of three factors, i.e., information quality, source credibility, and media richness, on participants’ HPV vaccination intent, via the mediation effect of attitude toward HPV vaccine information. Significant two-way interaction effects indicated that the persuasive effects of media richness varied across different levels of information quality and source credibility. This research not only applied the theoretical lens of the elaboration likelihood model and media richness theory to understand the influencing mechanism within short-form videos but also offered valuable guidelines regarding how professionals best adopt emerging media to maximize health outcomes.

5G enabled smart cities: A real-world evaluation and analysis of 5G using a pilot smart city application

Ubiquitous sensing in smart cities is expected to be one of the key beneficiaries of the high bandwidth and low latency capabilities of 5G. However, current 5G deployments still have low population coverage, and are unlikely to reach global coverage of above 80% before 2028. This means that new smart city applications are likely to experience a combination of 4G and 5G, limiting their data-intensive capabilities. Thus, it is necessary to assess the ability of current 5G deployments to support emerging smart city applications, and how they perform in 5G environments. Existing performance evaluations focus either on the 5G core or use instantaneous speed tests, which do not effectively assess the suitability of 5G deployments for smart city applications. In this paper, we present a comprehensive evaluation and analysis of real-world 5G network performance observed through the outcomes of a pilot smart city application, an innovative mobile 5G Internet of Things (IoT) solution to automatically identify and report road assets requiring maintenance. The pilot smart city application was deployed on 11 waste collection service trucks over a 6 month period (June 2022–Dec 2022). We undertook both application-specific and application independent network performance evaluation to assess the ability of the 5G deployment to support uninterrupted smart city services. Our analysis shows that while 5G is capable of supporting mobile video streaming applications, there are significant variations in network performance, which may make it unsuitable for applications that require higher data intensive or near real-time responsiveness.

Effect of improving asymmetry through self-myofascial release in adolescent soccer player with hypomobility syndrome hip: A randomized controlled trial.

Hypomobility syndrome (HMS), or limited hip range of motion (ROM), is often reported in adolescents who train heavily. This study was aimed to investigate the impact of traditional static stretching (STR) and self-myofascial release (MFR) in adolescents with HMS hip. This study was a randomized controlled trial. Adolescent athletes with HMS hip were grouped as 23 STR and 23 MFR. Foam rolling was employed as the training method for MFR. Both interventions were performed twice a day for 20 minutes in 6 weeks. The training was filmed and distributed via the mobile video. Self-assessed Copenhagen Hip & Groin Outcome Score, ROM, strength, and hop tests were measured before and after the interventions. The healthy side without limitations was designated as non-HMS (nHMS) and taken as reference value. The study participants had limitations in flexion (FLX), abduction (ABD), internal rotation (IR), and external rotation (ER). The ROM of STR group was recovered to nHMS level. The FLX and ABD of MFR group was also recovered, however the IR and ER had lower angles compared to nHMS. MFR FLX, ABD, ER strength, and single hop test were restored like that of nHMS, however STR group was substantially lower than nHMS despite the improvements. Both groups depicted lower pre-intervention Copenhagen Hip & Groin Outcome Score subscale activities daily living, sport, and physical activity compared to nHMS. Activities daily living and physical activity were improved to healthy levels after the intervention, however sport was lower than that of nHMS. Both STR and MFR had impact on hip mobility and hip self-assessment score. Furthermore, MFR had strength improvements in FLX, ABD, and ER. However, the improvements in MFR group regarding triples, crossover hops, and self-assessed sports were limited. Therefore, STR and MFR are effective in improving not only ROM but also muscle function asymmetry in HMS hip.

Rehabilitation in subjects with frozen shoulder: a survey of current (2023) clinical practice of Italian physiotherapists

ObjectiveFrozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions.AimThe aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature.MethodsA web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices.ResultsA total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients’ compliance with exercises at home and for motivational/educational purposes.Discussion and ConclusionThe clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

Energy and QoE Optimization for Mobile Video Streaming with Adaptive Brightness Scaling

Brightness scaling (BS) is an emerging and promising technique with outstanding energy efficiency on mobile video streaming. However, existing BS-based approaches totally neglect the inherent interaction effect between BS factor, video bitrate and environment context. Their combined impact on user’s visual perception in mobile scenario, leading to inharmonious between energy consumption and user’s quality of experience (QoE). In this paper, we propose PEO , a novel user- P erception-based video E xperience O ptimization for energy-constrained mobile video streaming, by jointly considering the inherent connection between a device’s state of motion, video quality and the resulting user-perceived quality. Specifically, by capturing the motion of the on-the-run device, PEO first infers the optimal bitrate and BS factor, therefore avoiding bitrate-inefficiency for energy saving while guaranteeing the user-perceived QoE. On that basis, we formulate the device motion-aware and user perception-aware video streaming as an optimization problem where we present an optimal algorithm to maximize the object function and adapt to user preference, and thus propose an online bitrate selection algorithm. Our evaluation (based on trace analysis and user study) shows that, compared with state-of-the-art techniques, PEO can raise the perceived quality by 23.8%-41.3% and save up to 25.2% energy consumption.

Selling Bonus Actions in Video Games

In the mobile video games industry, a common in-app purchase is for additional “moves” or “time” in single-player puzzle games. We call these in-app purchases bonus actions. In some games, bonus actions can only be purchased in advance of attempting a level of the game (pure advance sales (PAS)), yet in other games, bonus actions can only be purchased in a “spot” market that appears when an initial attempt to pass the level fails (pure spot sales). Some games offer both advance and spot purchases (hybrid advance sales). This paper studies these selling strategies for bonus actions in video games. Such a question is novel to in-app tools selling in video games, and it cannot be answered by previous advance selling studies focusing on end goods. We model the selling of bonus actions as a stochastic extensive form game. We show how the distribution of skill among players (i.e., their inherent ability to pass the level) and the inherent randomness of the game influence selling strategies. For casual games, where low-skill players have a sufficiently high probability of success in each attempt, if the proportion of high-skill players is either sufficiently large or sufficiently small, firms should adopt PAS and shut down the “spot” market. Furthermore, the player welfare-maximizing selling strategy is to sell only in the spot market. Hence, no “win-win” strategy exists for casual games. However, PAS can be a win-win for hardcore games, where low-skill players have a sufficiently low success probability for each attempt.

Effectiveness of Two Types of Distraction Techniques in the Management of Pain and Anxiety during Dental Treatment in 6-9-year-old Children.

To determine the effectiveness of distraction with virtual reality (VR) distraction devices in comparison with mobile phone video games in the management of pain and anxiety during dental treatment in 6-9-year-old children. It was a comparative observational study. A total of 33 children aged 6-9 years who reported to the department for their first dental visit were selected and the subjects were divided into three groups. Group I patients were in a normal clinical environment without any distractions. Group II patients were given mobile phone video games. Group III patients were given a VR distraction device as a means of distraction.The anxiety levels of patients before treatment, after using a distraction device preoperatively, during local anesthesia injection, and after dental treatment were assessed. Pain after local anesthesia injection in each group was assessed. The easability of handling the patient and carrying out the procedure was assessed using a questionnaire. All data were collected and analyzed. The results showed when compared to the children in groups I and II, children in group III obtained significantly lower anxiety scores after treatment, and they also reported significantly decreased pain perception during dental treatment (p < 0.001). The pain while administering local anesthesia was greater for the control group and lowest for the VR group. It was observed that VR group patients were easier to handle and easier to carry out procedures than those in the mobile phone group. Virtual reality distraction is an effective distraction technique for reducing pain and anxiety in children during various treatment procedures. Virtual reality distraction can be used effectively in clinics.It is a patient-friendly technique and is more comfortable for both patients and dentists during treatment.It does not require any previous education and training and has a positive impact on memories of the treatment, leading to behavior modification.

Efficacy of kaleidoscope, virtual reality, and video games to alleviate dental anxiety during local anesthesia in children: a randomized clinical trial.

Distraction is a technique used to divert a patient's attention from unpleasant procedures. This study aimed to evaluate the effectiveness of kaleidoscopy, virtual reality, and video games in reducing anxiety and pain during invasive dental procedures in children. Sixty-six children aged 6 to 9 years were randomly assigned to three groups during local anesthesia administration: Group 1 (kaleidoscope), Group 2 (virtual reality), and Group 3 (mobile video games). The anxiety of the children was evaluated using physiological measures (heart rate) at three different time points: before, during, and after the procedure. The Raghavendra, Madhuri, and Sujata pictorial scale was used as a subjective measure before and after the procedure. Subjective measures of pain were assessed using the Wong-Baker Faces Pain Scale. The data were statistically analyzed using the Kruskal-Wallis and Wilcoxon signed-rank tests. In the intergroup comparison, there were no statistically significant differences in the physiological measures of anxiety scores between the three groups before, during, and after distraction. Raghavendra, Madhuri, and Sujata pictorial scale scores were assessed before and after distraction, but no statistically significant differences were observed. Among the three groups, the children in Group 2 showed a significant reduction in pain scores. Compared with kaleidoscopes and video games, virtual reality is a promising distraction technique for reducing dental fear, anxiety, and pain during local anesthesia administration in children.

Disentangling composite influences of social connectivity and system interactivity on continuance intention in mobile short video applications: The pivotal moderation of user-perceived benefits

The expeditious proliferation of wireless network technology has caused the widespread integration of mobile short video apps into our daily routines, offering unprecedented opportunities for information dissemination and interactive communication. Despite extensive researches on the interactivity of mobile short video app, there has been a limited focus on understanding the underlying factors that contribute to users' perceived benefits and continuance intention. Leveraging insights from preceding studies, this study develops a conceptual research model that investigates how two distinct facets of interactivity, namely social interactivity and system interactivity, influence users' perceived benefits from mobile short video apps, ultimately impacting their intention to continue using them. This analysis rigorously scrutinizes data garnered from 808 users of mobile short video applications, employing structural equation modeling to validate the proposed hypotheses. The findings conclusively reveal that interactivity significantly affects users’ perceived benefits from mobile short video apps. Moreover, the study elucidates that perceived benefits from these apps are the significant predictors of continuance intention. Furthermore, interactivity could indirectly influence continuance intention via the mediation of perceived benefits. These findings possess the potential not only to augment our comprehension of perceived benefits and continuance intention from the interactivity perspective but also to furnish valuable insights for scholars in the field. The research sheds light on effective methodologies to encourage the adoption of mobile short video applications and to boost user engagement in a society oversaturated with mobile technology.
