Target Signal Communication Detection of Black Flying UAVs Based on Deep Learning Algorithm

Background: Unmanned aerial vehicles (UAVs) are being widely used in many fields, such as national economy, social development, national defense, and security. Currently, the number of registered UAVs in China is far less than that of flying UAVs-the frequent occurrence of unsafe incidents. Objective: The phenomenon of UAVs flying undeclared and unapproved has caused more serious troubles to social public order and people's production and life. Methods: In this paper, to assist the public security department in detecting the phenomenon of UAV black flying, our team conducts a series of research based on the deep learning YOLOv5 (You Only Look Once) algorithm. Results: Firstly, the Vision Transformer mechanism is integrated to enhance the robustness of the model. Secondly, depth-separable convolution is introduced to reduce parameter redundancy. Finally, the SimAM attention-free mechanism and CBAM attention-free mechanism are combined to enhance the attention of small target UAVs. Conclusion: Through the analysis of UAV targets in video surveillance, the rapid identification of black-flying UAVs can be realized, the monitoring and early warning ability of UAVs in a specific area can be improved, and the loss of life and property of people can be reduced or saved as much as possible.

Investigative Reporting Trends in Bangladesh: A Content Analysis of Selected Newspaper

The purpose of this research was to examine the actual state of investigative journalism in Bangladeshi print media. The content analysis method was used to scrutinize the investigative reports, employing both quantitative and thematic approaches. Four daily newspapers - The Daily Star, Prothom Alo, Bangladesh Protidin, and Juger Alo - were selected for analysis, with 61 copies from each, totaling 244 newspaper copies. The three national dailies were selected as the most circulated Bangla and English newspapers of Bangladesh according to the department of film and publications (DFP) and the local daily was chosen as per researcher convenience. The theoretical framework for this study utilized the social responsibility theories of the press and agenda-setting theory. The results indicated that a limited number of investigative reports were published in Bangladeshi daily newspapers, with the theme of economy-related issues receiving the most attention in investigative reporting. Concerns were raised regarding the high percentage of anonymous sources (41%) and second-hand investigation (69%), casting doubt on the quality of investigative reporting. Future research could explore a broader perspective of investigative reports through textual analysis conducted over an extended period.

The trajectory of serum salicylate concentrations after ingestion of medicinal oil containing methyl salicylate

Introduction The toxicokinetics of methyl salicylate after unintentional or intentional ingestion of medicinal oil containing methyl salicylate has not been well studied. We aimed to characterize the trajectory of serum salicylate concentrations and to evaluate factors associated with the peak serum salicylate concentration and the time from ingestion to peak concentration. Methods This was a retrospective cohort study of consecutive patients reported to the Hong Kong Poison Control Centre for laboratory-confirmed methyl salicylate poisoning by all local public emergency departments between 1 July 2008 and 30 June 2023. We analyzed cases with at least three serum salicylate concentrations. Multivariable generalized linear regression was used to identify factors significantly associated with the peak serum concentration and the time from ingestion to peak concentration. Results We included 41 patients (median age 81.0 years; 32 women and nine men). The median time from ingestion to the first peak serum salicylate concentration was 5.6 h (IQR: 3.2–10.8 h). Multiple regression showed that gastric aspiration (adjusted regression coefficient [β] − 2.50; 95% CI: −3.93 to −1.08; P = 0.001) and single-dose activated charcoal (adjusted β − 1.22; 95% CI: −2.02 to −0.42; P = 0.003) were significantly associated with a lower peak concentration, after adjusting for patient age, sex, exposure due to intentional self-harm, reported ingested dose, time from ingestion to emergency department presentation, vomiting, concurrent use of aspirin (acetylsalicylic acid) and other medications that affect gastric emptying or gastric acid secretion, blood pH, serum albumin concentration, and creatinine clearance. Discussion The serum salicylate concentration did not peak as quickly as generally believed, highlighting the importance of continued monitoring. Gastric aspiration and single-dose activated charcoal may help reduce gastrointestinal absorption, but their impact on clinical outcomes remains unclear. Conclusions Given the median time of 5.6 h (IQR: 3.2–10.8 h) from ingestion to the peak salicylate concentration, gastric aspiration and single-dose activated charcoal can be considered in patients up to a few hours after medicinal oil ingestion when the airway is protected.

Socioeconomic inequity in the utilization of healthcare among people with eating disorders in Australia.

Little is known about socioeconomic equity in access to healthcare among people with eating disorders in Australia. This study aims to measure the extent of inequity in eating disorder-related healthcare utilization, analyze trends, and explore the sources of inequalities using New South Wales (NSW) administrative linked health data for 2005 to 2020. Socioeconomic inequities were measured using concentration index approach, and decomposition analysis was conducted to explain the factors accounting for inequality. Healthcare utilization included: public inpatient admissions, private inpatient admissions, visits to public mental health outpatient clinics and emergency department visits, with three different measures (probability of visit, total and conditional number of visits) for each outcome. Private hospital admissions due to eating disorders were concentrated among individuals from higher socioeconomic status (SES) from 2005 to 2020. There was no significant inequity in the probability of public hospital admissions for the same period. Public outpatient visits were utilized more by people from lower SES from 2008 to 2020. Emergency department visits were equitable, but more utilized by those from lower SES in 2020. Public hospital and emergency department services were equitably used by people with eating disorders in NSW, but individuals from high SES were more likely to be admitted to private hospitals for eating disorder care. Use of public hospital outpatient services was higher for those from lower SES. These findings can assist policymakers in understanding the equity of the healthcare system and developing programs to improve fairness in eating disorder-related healthcare in NSW.

How Did Chinese Local Media Face Media Convergence? A Case Study of Qianxinan Daily

ABSTRACT Scholars have long examined media convergence, yet little attention has been given to its intersection with local media and main stream Chinese media controlled by the Chinese Communist Party (CCP). This study addresses this gap by employing focus groups and interviews to conduct a case study of Qianxinan Daily. Furthermore, the primary hypothesis posits that, under the leadership of the Party Committee, Qianxinan Daily has adapted to media convergence amidst the trend of media integration. The findings of this study reveal that Qianxinan Daily, under CCP leadership, benefits from stable resource access and avoids direct market competition pressure. However, this also results in organizational and reporting constraints imposed by the Party Committee’s Publicity Department in Qianxinan. While Qianxinan Daily has established a relatively solid framework, there remains significant room for improvement in manuscript quality and news value in the context of media convergence. This conclusion enriches our understanding of media convergence dynamics and highlights the influence of the CCP on this phenomenon.

Association Between Oral Fluoroquinolones and Neuropsychiatric Events: Self-Controlled Case Series With Active Comparator Design.

The evidence of the neuropsychiatric effects associated with fluoroquinolones is mainly supported by case reports. Population-based evidence remains largely limited. We aimed to investigate the association between the use of fluoroquinolones and hospitalization or Accident & Emergency department visits for acute neuropsychiatric events using a self-controlled case series (SCCS) and active comparator to reduce confounding. We conducted a SCCS with a recently described active comparator design using all public outpatient clinics, hospitalization, and Accident and Emergency department records from the Clinical Data Analysis and Reporting System, Hong Kong from 2001 to 2013. Among 166 325 people with an oral fluoroquinolone prescription, 4287 people who had an incident neuropsychiatric event were included. We then estimated the incidence rate ratio (IRR) of acute neuropsychiatric events during periods before and after fluoroquinolone prescription, versus baseline. We repeated the analysis for amoxicillin/clavulanic acid users as an active comparator. We then estimated the comparator-adjusted estimates by dividing the IRR for fluoroquinolone by the IRR for amoxicillin/clavulanic acid. The primary outcome was neuropsychiatric events. Secondary outcomes were psychotic events and cognitive impairment. An increased risk of neuropsychiatric events was observed in the current use of fluoroquinolone [IRR: 2.11 (95% confidence interval (CI): 1.58-2.83)] and 1-7 days after the end of fluoroquinolone prescription [IRR: 1.90 (95% CI: 1.30-2.75)] versus baseline. No increased risk was observed in other risk periods versus baseline. Similar patterns were observed in the current use of amoxicillin/clavulanic acid [IRR: 1.92 (95% CI: 1.19-3.11)] and 1-7 days after the end of fluoroquinolone prescription [IRR: 1.81 (95% CI: 1.11-2.97)] versus baseline. Similar results were found for secondary outcomes. Using the active comparator design, comparator-adjusted estimates were 1.10 (95% CI: 0.63-1.93) in current use of fluoroquinolones and 1.05 (95% CI: 0.57-1.95) in 1-7 days postexposure to fluoroquinolones versus baseline. Although our study showed a higher incidence of neuropsychiatric events in the current use of fluoroquinolones and 7 days after the end of fluoroquinolones prescriptions compared with baseline, a similar temporal pattern was also found for amoxicillin/clavulanic acid users. Using amoxicillin/clavulanic acid as the active comparator, we found no difference in the risk of neuropsychiatric events associated with fluoroquinolone compared with baseline. Therefore, the risk of neuropsychiatric events may not need to influence the decision to prescribe either fluoroquinolones or amoxicillin/clavulanic acid based on the evidence in this study.

High-Sensitivity Cardiac Troponin T Reporting, Clinical Outcomes, and Health Care Resource Use

Despite being recommended by clinical guidelines, substantial concerns remain regarding the use of high-sensitivity cardiac troponin assays and whether it is associated with increased resource use, myocardial infarction (MI) or myocardial injury diagnoses, and procedural rates. To characterize the association of reporting high-sensitivity cardiac troponin T (hs-cTnT) to the lowest limit of quantification vs conventional troponin reporting with clinical outcomes. This cohort study used a historically controlled baseline and follow-up design to compare clinical outcomes after changing hs-cTnT reporting to the lowest limit of quantification. All patients aged 18 years or older presenting to any public emergency department (ED) in the state of South Australia between February 1, 2020, and February 28, 2021, who had an hs-cTnT test in the 6 months before and after the change in troponin reporting practice were included. Outcomes were assessed after adjusting for patient characteristics using inverse probability treatment weighting. The data analysis was performed between May 1, 2022, and July 27, 2023. hs-cTcnT reporting. The main outcomes were frequency of diagnosed MI, coronary angiography, percutaneous coronary intervention, and coronary artery bypass graft (CABG); hospital length of stay; and ED discharge rate as measured using time-to-event Cox regression models. The secondary outcome was the composite 12-month event rate of all-cause mortality, MI, and myocardial injury. A total of 40 921 patients were included, of whom 20 206 were included in the unmasked hs-cTnT reporting group (median [IQR] age, 62.0 [46.0-77.0]; 10 120 females [50.1%]) and 20 715 were included in the conventional troponin reporting group (median [IQR] age, 63.0 [47.0-77.0] years; 10 752 males [51.9%]). Unmasked hs-cTnT reporting was associated with higher ED discharge rates (45.2% vs 39.0%; P < .001) and a shorter median hospital length of stay (7.68 [IQR, 4.32-46.80] hours vs 7.92 [IQR, 4.56-49.92] hours; P < .001). There was no difference in diagnosis of MI, coronary angiography, percutaneous coronary intervention, or coronary artery bypass graft. The composite of all-cause mortality, MI, and myocardial injury at 12 months was similar (adjusted hazard ratio, 0.95; 95% CI, 0.90-1.01; P = .09). This cohort study found that unrestricted reporting of hs-cTnT results to the lowest limit of quantification was not associated with an increase in the diagnosis of MI, invasive coronary procedures, or harm at 12 months but may be associated with improved hospital resource use.

Altered Sensory Processing in People Attending Specialist Orthopaedic Consultation for Management of Persistent Shoulder Pain: An Observational Cross-Sectional Study.

OBJECTIVES: The primary objective was to compare sensory processing measures in people attending specialist orthopaedic consultation for management of persistent shoulder pain with control participants. The secondary objective was to compare the groups' sociodemographic, clinical, general health and lifestyle, and psychological characteristics. DESIGN: Observational cross-sectional. METHODS: Participants with shoulder pain for ≥3 months, who attended a public hospital orthopaedic department (n = 119), and community participants without shoulder pain (n = 44) underwent a standardized quantitative sensory testing protocol, measuring pressure pain threshold, temporal summation, and conditioned pain modulation. Sociodemographic, clinical, general health and lifestyle, and psychological characteristics were also collected. RESULTS: Participants with shoulder pain had significantly lower pressure pain thresholds at all sites (ie, local and widespread mechanical hyperalgesia) and significantly decreased conditioned pain modulation effect (ie, descending inhibition of nociception) than control participants. There was no significant difference between groups for temporal summation. Participants with shoulder pain had decreased general health and function, less healthy lifestyles, and poorer psychological health compared with controls. CONCLUSION: People referred to specialist orthopaedic care for management of persistent shoulder pain had clinical signs of altered sensory processing and poor health outcomes.

Adult Sports Participation and Physical Activity: How About Curling?

Despite its well-documented physical and psychosocial benefits, sport remains the least engaged form of physical activity (PA) among adults. Many adults may lack the skills needed to play or continue to play sports and aging adults are more likely to avoid participation for fear of poor performance or injury. A sport that shows great promise for adults seeking new sports participation outlets is curling. Curling is a team sport comprised of four interchangeable positions working collectively to deliver granite stones across a sheet of ice in an effort to outscore the opponent team. While it seems reasonable that walking on ice, “throwing” a 44 lb granite stone across a sheet of ice, and periodically sweeping while walking on ice over a two-hour period would generate at least a moderate amount of physical activity, research to date is quite limited. Therefore, the purpose of this study was to objectively measure the amount and intensity of PA achieved by average recreational curling participants during a typical curling match. Methods Members of a curling club in NC were asked to wear Actigraph Accelerometers (model GT3X) while they participated in their regularly scheduled curling match. All participants had at least one year of curling experience. Curling matches lasted between 90 and 120 minutes. Participants were asked to indicate their age, gender, and curling position during the match (lead, second, vice, skip) which were matched with accelerometer data. Results Overall, 110 participants (37 female, 73 male, avg. age 50 yrs) spent most of their curling time in light or moderate-intensity activity (18.1% Sedentary; 49.5% light; 32.4% moderate; .03% vigorous). In terms of minutes, the average participant spent 35.9 minutes engaged in Moderate-to-Vigorous PA (MVPA) per curling experience. This represents 23.9% of the weekly 150min of MVPA suggested by the CDC. The second position had the highest percentage of moderate activity level and a small percentage of vigorous activity. No other position reached a vigorous level. The skip position had the highest amount of sedentary activity as well as light activity. Females had a higher level of moderate activity in comparison to males. However, males reached a small amount of vigorous activity. The age group of 18 - 36 had the highest amount of moderate activity and the lowest amount of sedentary activity. This age group reached an average of 41.0 minutes of MVPA per curling experience. The age group of &gt; 58 had the highest amount of sedentary activity and the lowest amount of moderate activity. Conclusions Curling may be a good sports participation option for adults looking for alternatives to meet recommended weekly amounts of MVPA. Participants should consider playing in one of the first three positions to maximize the amount and intensity of PA achieved while playing. Furthermore, since curling also requires balance, coordination, muscular strength, multitasking, strategic reasoning, and can cater to most physical challenges without compromising the integrity of the game, it may be an ideal sport to promote for adults of all ages and sport abilities. Implications for Practice and Policy Findings should be used to inform strategies for promoting curling as an opportunity for team sport involvement that has the added value of contributing to daily physical activity. However, , access and opportunities to play, especially for underserved populations, are limited. Given that most curling clubs in America are private and require a membership to play. Partnership arrangements between existing clubs and public parks and recreation departments could increase both access and opportunities to play.

Hospitalisations for non-specific low back pain in people presenting to South Australian public hospital emergency departments.

The present study sought to investigate predictors of hospitalisation in adults diagnosed with non-specific low back pain (LBP) and/or sciatica from an ED. A 5-year, multicentre retrospective observational study was conducted across six public hospitals (metropolitan and regional) using data from electronic medical records. Patient presentations were identified using LBP diagnostic codes and key data extracted (patient demographics, clinical activity, discharge destination). Descriptive statistics and logistic regression were used to measure associations between identified variables and hospitalisation. There were 11 709 ED presentations across the study period. People aged ≥65 years (odds ratio [OR] 2.84, 95% confidence interval [CI] 2.61-3.10) and those who arrived at the ED via ambulance (age-adjusted OR 2.68, 95% CI 2.44-2.95) were more likely to be hospitalised. People were also more likely to be hospitalised when triaged as more urgent, when blood tests or advanced spinal imaging were ordered, and when i.v./subcutaneous opioids or oral benzodiazepines were administered. Hospitalisation rates for LBP were lower in regional hospitals, in people residing in lower socioeconomic areas and in Indigenous Australians. Certain patient characteristics and ED clinical activity are associated with hospitalisations for LBP. Understanding these factors will better inform the design and delivery of appropriate high-quality care.

Prediction of Employees’ Addiction Potential Based on Some of the Most Important Psychological Variables: A Discriminant Analysis Study

Background: Drug addiction significantly impacts employee performance, leading to increased absenteeism, reduced productivity, and higher rates of occupational accidents. Therefore, identifying predictive factors for addiction potential is crucial in preventing drug dependence. Objectives: This study aimed to develop a group membership model using discriminant analysis to predict employees' potential for addiction based on key psychological variables. Methods: A correlational study was conducted with a statistical population consisting of all employees working in public departments in Bojnord City, Iran, in 2021 (N = 2,837). A random sample of 303 employees was selected to complete the Iranian Form of the Addiction Potential Scale, the Big Five Inventory, the Cognitive Emotional Regulation Questionnaire, and the Generalized Self-Efficacy Scale. Data analysis was performed using the discriminant analysis method in SPSS software version 23. Results: The findings revealed that employees' addiction potential can be predicted using personality and cognitive variables. The discriminant analysis equation effectively distinguishes employees with high and low addiction potential based on psychological variables, including extroversion, neuroticism, self-efficacy, and cognitive emotional regulation. Conclusions: The study concluded that self-efficacy, cognitive emotional regulation, neuroticism, and extroversion are significant predictors of addiction potential. It is recommended to incorporate these variables into training courses and personnel selection processes for government jobs.

Workplace violence in three public sector emergency departments, Gauteng, South Africa: A cross-sectional survey

IntroductionWorkplace violence against healthcareworkers in Emergency Departments (EDs) is a global concern. The purpose of this study was to determine the prevalence and types of workplace violence in EDs. Methodsa cross-sectional survey was conducted in three public sector hospital EDs in Gauteng, South Africa. A self-administered, standardised online questionnaire developed by the World Health organization was used to collect data between March and November 2022. A total of 65 healthcareworkers which consisted of nurses (24) and doctors (41) participated in the study. ResultsThe prevalence of workplace violence was 73.8 % with verbal abuse being the most common type at 66 %. Eighty-two percent of the victims did not report the incident. Poor communication and lack of mutual respect among staff and healthcare users contributed to both physical and non-physical workplace violence. ConclusionWorkplace violence appears to be a common occurrence in EDs in the hospitals surveyed in Gauteng. It is regarded as a typical incident by respondents, and it is underreported. It has a direct negative impact on healthcareworkers and their working environment and indirectly on patients. Urgent attention from all stakeholders is needed to minimize the prevalence of these incidents.

Efficacy of continuous employee learning and development in the South African public service between 2014 to 2023 era

Modern technologies have intensified innovations and necessitated changes in public service processes and operations. Continuous employee learning development (CELD) is one means of the molecule-atom that keep employees motivated and sustain competitiveness. The study explored the efficacy of CELD in relation to modern technology in the South African (SA) public service departments between 2014 to 2023 era. Departments are faced with challenge of equipping their employees with adequate professional and technical skills for both the present and the future in order to deliver specific government priorities. Data for the study were gathered utilizing a qualitative semi-structured e-questionnaire. The study sample consisted of 677 human capital development practitioners from national and provincial government departments in SA. The inefficacy CELD and the inadequacy of technological infrastructure and service delivery can be attributed to the failure by executive management and senior managers to invest in CELD to prepare employees for digital world. It is recommended that departments should use Ruggles’s knowledge management, Kirkpatrick’s training, and Becker and Schultz’s human capital models as sound measurement tools in order to gain a true return on investment. The study adds pragmatic insight into the value of CELD in the new technological environment in public service departments.

Graduate public health student learning experiences, social connectedness, and mental health during COVID-19: pedagogical implications for public health academic departments.

The COVID-19 pandemic impacted college student learning both globally and nationally. Current literature points to decreases in social connectedness, adverse mental health outcomes, and decreased overall learning outcomes; however, there are limited findings from higher education institutions within the Bay Area, California. There are also limited studies that examine the COVID-19 impact among public health graduate students, especially to understand how the pandemic renewed their interest in the field. The purpose of this study was to investigate the effects of COVID-19 on graduate student learning experiences, social connectedness and mental health within the Master of Public Health program at San José State University in San Jose, California. We employed a convergent mixed-methods design using a survey that quantitatively assessed student learning experiences through a retrospective pre-and post-design, and a semi-structured interview guide that qualitatively assessed student learning experiences and its relationship with mental health and social connectedness using a phenomenological design. Data were collected between September 2022 and June 2023 and analysis was performed using descriptive statistics and thematic analysis. A total of 22 students completed the survey and four participated in follow-up semi-structured interviews. Of the 22, 12(54%) were among the 18-29-year age group, 9(41%) identified as Asian, 21(95%) identified as female, and 9(41%) identified as a first-generation college student. When comparing survey responses, the median change in learning experiences pre and during-pandemic were statistically significant across several areas such as student ability to stay organized (p < 0.0001), participate actively in class (p < 0.001), retain course material (p < 0.0001), collaborate with peers (p < 0.0001), and maintain a sense of connection with their cohort (p = 0.0001) and broader campus community (p < 0.0001). Semi-structured interviews further revealed the following six themes: (1) Consistent faculty support; (2) Sense of community; (3) Reduced social connectedness; (4) Impact on mental health; (5) Deeper public health understanding; and (6) Facilitators and barriers. Educational practitioners are encouraged to offer hybrid academic programs and establish resource infrastructures that provide students with social and mental wellness support when transitioning to different learning modalities.

Football-Generated Rent Sharing and Expenditures on Women’s Intercollegiate Athletics

Recent research contains evidence of rent sharing in intercollegiate athletic programs from revenues generated by football and men’s basketball and regulations restricting compensation to athletes. Title IX mandates equal opportunities for male and female college athletes, clearly impacting athletic department budgets. These factors create a rich environment for analyzing athletic spending decisions. We analyze spending on women’s sports for about 120 NCAA public FBS athletic departments. Results from instrumental variables models that account for the endogeneity of the rent proxy variable, head football coach salary, indicate the presence of rent sharing from football-generated rents to spending on women’s sports.

Development of a team-specific research strategy using a modified Delphi method in a regional public hospital dietetics department.

Evaluate research capacity and culture among regional hospital dietitians, develop a team specific research strategy, and build research skills of novice researchers. The Research Capacity in Context Tool was used to assess current research capacity and culture at organisational, team and individual levels. Results were analysed using descriptive statistics and content analysis of free text responses. A modified Delphi method gained consensus regarding research capacity building. Mixed method study. Dietetics department of a regional tertiary hospital (Modified Monash Category 2). All clinical dietitians currently employed within the hospital (n = 20) regardless of employment duration. Self-rated response to research capacity and culture to produce a dietetics-specific research strategy. Fifteen dietitians (75%) completed the Research Capacity in Context Tool. The overall mean score was highest at an organisational level at 7.9 (IQR 2), and lowest at team and individual levels at 4.3 (IQR 2.7) and 4.9 (IQR 3.3) respectively. Common barriers to research included time, lack of skills, knowledge and support. Using the modified Delphi method 39 statements relating to research capacity building met consensus and informed the creation of a research strategy. The results of the Research Capacity in Context Tool from this regional study reflect those reported in the literature at metropolitan sites. A dietetic-specific research strategy was developed to assist with increasing research capacity at a team and individual level in a regional setting. Evaluation of long-term outcomes post implementation will be the subject of further research.

Unraveling the propagation dynamics of passenger congestion in public transportation systems using big smart card data

We propose a comprehensive framework to explore propagation of passenger crowdedness in public transportation systems using 74.16 million trip chains. A deep learning method HSTGCNT is adopted which firstly models normal spatio-temporal dependencies in time series data, and assigns an anomaly score to new data based on its prediction error. The derived discrete anomaly events are further aggregated into groups based on their spatio-temporal proximity by using a clustering algorithm that binds shared nearest neighbors together based on pairwise correlations. The clustering results uncover several key stages located in a propagation chain, such as a core event, adjacent events with spatio-temporal proximity, or a broadcasting group. Weibo data serves as a third-party dataset to verify the above anomaly clusters. Results show that the framework is effective to detect outlier clusters, with recall value being 0.86. Findings may assist public safety departments in taking pro-active actions to interrupt chaos from broadcasting.
