Tourism Recommendation Algorithm Based on the Mobile Intelligent Connected Vehicle Service Platform

As to the problems in current tourism recommendation, this paper proposes a tourism recommendation algorithm based on the mobile ICV service platform. Firstly, the ICV service system for the Point of Interest (POI) searching and route recommendation is designed. Secondly, the recommendation service model is set up from two aspects, namely the tourism POI clustering algorithm and the tourism POI searching and route recommendation algorithm. In the aspect of symmetrical-based matching features, the clustered POIs are matched with the tourists’ interests, and the POIs in the neighborhood of the ICV dynamic locations are searched. Then, a POI recommendation algorithm based on the tourists’ interests is constructed, and the POIs that best match the symmetrical interests of the tourists within the dynamic buffer zones of ICV are confirmed. Based on the recommended POIs, the ICV guidance route algorithm is constructed. The experiment verifies the advantages of the proposed algorithm on the aspect of the POI matching tourists’ interests, algorithm stability, traveling time cost, traveling distance cost and computational complexity. As to the iterative sum and the iterative sum average of the POI matching function values, the proposed algorithm has a performance improvement of at least 20.2% and a stability improvement of at least 20.5% compared to the randomly selected POIs in matching tourists’ interests. As to the cost of the guidance routes, the proposed algorithm reduces the average cost by 19.6% compared to the other suboptimal routes. Compared with the control group algorithms, the proposed algorithm is superior in terms of route cost, with an average cost reduction of 13.8% for the output routes compared to the control group. Also, the proposed algorithm is superior in terms of route cost compared to the control group recommendation algorithms, with an average cost reduction of 11.2%.

Pertussis on the territory of Serbia in 2024 - challenges and opportunities for the future

Abstract Introduction Surveillance of pertussis in Serbia is passive surveillance and every 3 to 4 years an increased number of positive cases are registered in the population. The last quarter of 2023 and the first quarter of 2024 are characterized by an increased number of pertussis cases. Methods Descriptive study of cases with confirmed pertussis in the territory of the Republic of Serbia based on the evidence by the Public Health Service System of the Institute of Public Health of Serbia Results According to data from the Public Health Service System in the Republic of Serbia, a total of 1348 confirmed cases of pertussis were registered by the end of April 2024 (incidence rate 20.2 per 100,000 inhabitants). Conclusions The largest number of cases was registered in the age groups of people older than 20 years, that is, aged 10 to 14 years, while the highest age-specific incidence rate was recorded in the age group of infants younger than 12 months and in children aged 10 to 14 years. Of the total number of reported cases, 120 (8.9%) were hospitalized, with the largest number of those hospitalized being in the age group younger than 12 months (85, ie 70.8% of hospitalized cases). As for the territorial distribution, the largest number of pertussis cases in relation to the place of residence was reported from the territory of two districts, Južnobački District and the City of Belgrade, where the highest incidence rates were also registered. The postponement of timely vaccination against pertussis and the impossibility of vaccinating newborns up to 2 months of age have influenced the increase in the number of infected persons. Also, advanced PCR diagnostics during Covid and the possibility of applying PCR diagnostics in pertussis helped the timely diagnosis of pertussis. The introduction of vaccination with another dose of acellular pertussis vaccine and vaccination of pregnant women would be a desirable public health intervention to prevent pertussis infection. Key messages • Protection of the target population before starting school and at the age of 14 will contribute to stopping the occurrence of new cases of pertussis. These are public health challenges. • PCR diagnosis of pertussis influenced the timely diagnosis of this infection and the possibility of its adequate and timely treatment.

Can the National Public Cultural Service System Demonstration Zone Promote the Sustainable Development of Urban Culture?

The public cultural service system is a crucial component of urban culture and a key driver of cultural vitality and sustainable cultural development. This study leverages the “quasi-natural experiment” created by the establishment of National Public Cultural Service System Demonstration Zones to evaluate their impact on the sustainable development of urban culture. Using panel data from 295 prefecture-level cities between 2008 and 2019 and employing the difference-in-differences method, the study assesses how these zones influence cultural vitality. The findings reveal that the creation of these demonstration zones significantly boosts cultural investment and support, enhances cultural vitality, and promotes sustainable urban cultural development. Over time, this positive impact strengthens, particularly through increased cultural input driven by residents’ consumption patterns and urban economic growth. Additionally, the policy effects vary across regions and cities, depending on the level of tertiary industry development.

Promoting equality in utilization of basic public health services in China: the role of the family doctor contract service

Background The Family Doctor Contract Service (FDCS) system is a service model for primary care reform launched in 2016 to offer families and individuals active and continuous health care by a team of family doctors within primary care institutions in China. Objectives This study aimed to estimate socioeconomic-related inequalities in the utilization of basic public health services, and to identify the contribution of FDCS to promoting equality. Methods Data for the study were collected from a 2023 cross-sectional household health survey in western China, involving 39,456 participants. The concentration index (C) was employed for analyzing the extent of socioeconomic-related inequalities in the utilization of basic public health services and the coarsened exact matching technique was employed for sensitivity analysis in order to reduce selection bias. Results Our results indicated pro-poor inequalities in the utilization of health records (C = −0.046), free health check-ups (C = −0.009), and follow-ups for hypertension (C = −0.051). Additionally, a more equitable distribution across the economic spectrum was observed within the FDCS group (people who voluntarily contracted for services) compared to the non-FDCS group. The FDCS demonstrated more favorable positive impacts among individuals with higher (quintiles 60–80%) and the highest (top 20%) socioeconomic status. The FDCS contributed 83.94%, 59.24%, and 36.92% to pro-poor inequalities in the utilization of three basic public health services. These contributions reflected the positive impact of the FDCS on utilization. Conclusions Government policy and service delivery models require a paradigm shift to promote a stronger primary healthcare approach to practice, as evidenced by the effectiveness of the FDCS in promoting equality.

Experiences in healthcare for weight management – a qualitative interview study of retired individuals with obesity and low or high education

BackgroundOverweight and obesity are global health concerns, especially significant for older adults at higher risk for chronic diseases. The transition to retirement, altering daily routines, highlights the need for adequate weight management support. Since obesity is a challenging topic in healthcare and socioeconomic inequalities exist in access and utilization, we examined how retired individuals with obesity and low or high education describe their experiences of unmet needs, mismatches, and successes within the healthcare service system for weight management.MethodsThis qualitative interview study is part of the Helsinki Health Study. The participants (N = 20, with a body mass index of at least 30 kg/m2) were selected from a cohort of retired former employees of the City of Helsinki. Half of the interviewees had low education, and the other half had high education. Women and men were equally represented. The interviews were conducted in 2023 and the data were analyzed using inductive thematic analysis.ResultsThree main themes were formed: Deficiencies in engaged care, Services are mismatched with needs, and Facilitating conditions for individual successes. The first main theme had two sub-themes: Condescending attitude and Ignoring weight during the appointment. The second main theme had one sub-theme: Inadequate personnel resources. The third main theme had one sub-theme: Individual opportunities to acquire information and treatment. Educational differences were most clearly reflected in the sub-themes. Participants with low education more often described experiencing a condescending attitude towards them when seeking care and had had difficulties in obtaining time for appointments due to inadequate resources. Participants with high education described broader experiences related to individual opportunities to acquire information and treatment within the healthcare service system than participants with low education.ConclusionsThe participants in this study highlighted the importance of respectful engagement with the subject of their weight and felt that these kinds of interaction skills should still be developed in healthcare personnel. The participants articulated a need for approaches that are tailored to their unique circumstances. According to the participants, long-term group intervention, provided with peer support and supported by a multidisciplinary team, could sustain their weight management.

A network meta-analysis of different acupuncture therapy in the treatment of poststroke cognitive impairment and dementia.

Poststroke cognitive impairment and dementia (PSCID) is a major cause of stroke-related morbidities and mortalities. Over the last few years, there has been growing evidence supporting the effectiveness of needle-related treatments in PSCID. Our goal was to rate the included therapies and assess the clinical effectiveness of various needle-related treatments in patients with PSCID. We searched PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Chinese Biomedical Literature Service System (SinoMed), Wanfang, FDA.gov, and ClinicalTrials.gov. A mix of subject terms and free words was used to search the databases. The retrieval period was from the inception date of the database to February, 2023. We included SRs and MAs from acupuncture RCTs of patients with PSCID. The Cochrane Risk Assessment Scale was used to evaluate the risk of bias in the included studies. State 17.0 was used for network meta-analysis in accordance with the Bayesian framework. There were 34 studies total of 2690 patients. The cumulative ranking curve (SUCRA) revealed that CT + CFT + EA was the most efficient intervention to improve (Mini-Mental State Examination, MMSE) efficiency, followed by CT + CFT + AP to improve (Montreal Cognitive Assessment, MoCA) efficiency, CT + CFT + ACU for improving (Activities of Daily Living scale, ADL) scores, and CT + CFT + EA to improve clinical efficiency. The results show that Different acupuncture methods can improve cognitive function and daily living ability in patients with PSCID. Network meta-analysis revealed that both CT + CFT + ACU and CT + CFT + EA appeared to be more beneficial for daily living activities, while CT + CFT + EA and CT + CFT + AP appeared to be more helpful for cognitive performance in patients with PSCID. Treatments including acupuncture are safer and have a reduced incidence of negative side effects.

Raciality, intersubjectivity and transgression in the Brazilian system of socio-educational services: insights for social education

Social work and social pedagogy deal with a diverse and intricate set of social realities, while facing major issues such as racism and interracial relations. In this article, we look at studies of racism in Brazil and data from research into intersubjectivity conducted in the context of Brazilian socio-educational services. We also consider the ideas of Paulo Freire and bell hooks, notably bell hooks’s conception of transgression in an engaged pedagogy and Paulo Freire’s pedagogy of the oppressed and pedagogy of hope. We present and discuss a theoretical model for addressing ethnic-racial issues and racism in educational settings, involving processes of peripherisation, exclusion, invisibilisation and elimination. We aim to offer insights into social education and social work, departing from the articulation of studies of raciality, intersubjectivity, transgression and education as a practice of freedom. These insights can inform social pedagogy and the development of effective public policies and offer a broader perspective on the role of education and social work in promoting social justice and anti-racism in diverse educational settings, such as youth justice.

The effect of intersection vehicle scheduling based on the service system of sensors and intelligent traffic road information

With the high-speed development of the automobile industry, the number of domestic vehicles has increased significantly, which has posed a great challenge to the efficiency of road access. To fully utilize the intersection scheduling function of the intelligent transportation system, an optimization of the stranded traffic system based on LoRa is studied. Then, the greedy strategy and adaptive coefficient are used for optimization to obtain an improved genetic algorithm (GA), which is used to verify the intersection scheduling function. In addition, comparative experiments are conducted with standard GA, adaptive genetic algorithm (AGA), and hybrid genetic algorithm (HGA). The AGA optimizes the GA by adapting genetic parameters, while the HGA combines GA with a simulated annealing algorithm. The results showed that comparing the improved GA with GA, AGA, and HGA, the improved GA reduced the average value of individual extremum by 50.36%, 47.51%, and 37.16%, respectively. Compared with other mainstream algorithms, the improved GA reduced the number of stranded vehicles at intersections to 0 during traffic light timing. This indicates that the improved GA has higher and better performance and scheduling advantages in the intersection scheduling of intelligent transportation road service systems. The research aims to provide new ideas for improving traffic efficiency in intelligent transportation systems and promoting the informatization development of modern traffic management.

Pelvic Traumas and Hybrid Emergency Medicine System: Literature Review Based on Two Cases

Objective: Bleeding, the most common life-threatening complication of pelvic trauma occurs due to injuries of pelvic arterial and venous structures and bone fractures. The outcomes of patients can be improved by a timely performed angioembolisation (AE). Hybrid Emergency Service System (HERS) has been recently introduced a novel approach which provides trauma resuscitation room equipped with computerized tomography, fluoroscopy, and an operating room, thus effects the outcomes of trauma patients. Cases: We presented two pelvic traumas and in both cases with the most common life-threatening complication was bleeding. In both cases, whole-body computed tomography (WBCT), endovascular procedures (Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), transcatheter arterial embolization (TAE)), and injury control surgery can be simultaneously performed without the need to transport a patient to an operating room which is called HERS resuscitation. Both patients were discharged and remained free of any medical problem at long-term (12 months) follow-up. Conclusion: Considering the recently introduced HERS system in patient management and integrating it into emergency services will be extremely useful in the management of trauma and trauma-induced bleeding.

Database Construction and Application of Large-scale Geospatial Data

Abstract. Geospatial data refers to data that related to spatial location. It is the abstract representation of objects, events, or other characteristic information located on or near the surface of the Earth. It characterizes attribute features, spatial features, and associated information of geospatial features. Geospatial data commonly include various data types such as point, polyline, polygon, and so on. Geospatial database is the basic method to store and manage geospatial data. It is also the important component of geographic information systems (GIS). Geospatial database generally stores data in a specific structure in a medium, which can achieve efficient management of geospatial data. Users can add, modify, and delete data efficiently. Furthermore, query retrieval and statistical analysis can be quickly performed based on geospatial database. In this paper, distributed geospatial database is constructed by using database partition tables storage technology. Meanwhile, database construction software is developed to achieve the construction, management, and application of large-scale geospatial data. It can improve data import, query and retrieval efficiency significantly. The database application service system can directly connect to the database for displaying statistical analysis results. At the same time, geospatial data are processed to vector tiles, which stored in the tile database. Furthermore, standard online service is then published, which can be used for database management and application service system. It can be used for natural resource management work such as basic surveying, survey and monitoring, and so on.

Investigating quality service and student satisfaction: evidence from College of Business & Economics, University of Gondar, Ethiopia

Providing quality service is the major concern of many public organizations. However, the way to provide immediate service (responsiveness), the capacity to deliver on promises of accurate and consistent service (reliability), the degree of trust and confidence of students in the service provided by the college (assurance), the physical appearances of the service that the college offers (tangibility) and understanding the needs of students in the college are not as such potential. Thus, the study aims to investigate the effect of a quality service system on student satisfaction in Business and Economics College, University of Gondar. An explanatory research design with a quantitative research approach was employed to address the specified objectives. The population of the study was 6323 and out of these, 376 samples were drawn through stratified random sampling technique. Of 376 self-administer questionnaires, 263 were valuable for this analysis. One of the objectives of the study was to understand the dominant service quality dimension. The finding of the mean score of SERVQUAL dimensions portrays that students are less satisfied with dimension responsiveness (M = 2.31), which implies that the way students get an immediate response for their need showed very low followed by dimension empathy (M = 2.63) i.e., the willingness of staff to support or help students, spontaneous care and concern of staff to student’s needs, is lower, whereas with tangibles, assurance, and reliability are better. The PLS-SEM analysis result confirmed that tangibility and assurance has a significant effect but other service quality dimensions are not.

A meta-analysis of the relationship between overtime work and neck musculoskeletal disorders in Chinese occupational population

Objective: To systematically evaluate the effect of overtime work on neck musculoskeletal disorders of occupational population in China. Methods: In August 2023, the literatures on the relationship between overtime work and neck musculoskeletal disorders were searched in China National Knowledge Infrasture (CNKI), WanFang Database, Chinese Science & Technology Journal Database (VIP), China Biomedical Literature Service System (SinoMed) and PubMed. The search scope was Chinese and English literatures published before June 30, 2023. The Quality of literature studies was evaluated using the Agency for Healthcare Research and Quality (AHRQ) cross-sectional study quality evaluation criteria. The Stata 15.0 software was used to calculate combined OR values, and subgroup analysis and meta regression were used to explore the sources of heterogeneity. Results: A total of 32 literatures were included, all of which were in Chinese, with a total sample size of 36003 people, and the literature quality scores were 5-7 points. Heterogeneity test showed that there was no heterogeneity between the literatures (I(2)=20.3%, P=0.156), so fixed effect model was selected to calculate the combined OR value. The combined OR value of overtime work on neck musculoskeletal disorders was 1.51 (95%CI: 1.42-1.60, P<0.001). Subgroup analysis showed that the combined OR of occupational population <35 years old group was higher than that in the ≥35 years old group (P<0.05). But there were no significant differences in the combined OR values in the subgroups classified by average years of service, male proportion, type of OR values, sample size and industry classification (P>0.05) . Conclusion: Overtime work is a risk factor for neck musculoskeletal disorders in Chinese occupational population. Working hours should be rationally arranged to reduce the prevalence of neck musculoskeletal disorders.

Elements of trust and trust-building in gerontological social work. The social worker’s perspective

ABSTRACT Although trust between social workers and their clients emerges as a critical factor in social work, it has often been taken for granted and rarely placed under detailed scrutiny in social work research. This study explores the elements on which clients’ trust is built, and social workers’ trust-building practices in gerontological social work (GSW) in Finland. We analysed seven focus group discussions of gerontological social workers abductively, using Russell Hardin’s model of trust as an analytical tool. This study identifies six elements of clients’ trust: (1) trust in the individual social worker and in the institution, (2) trust as mutually recognised goals, (3) trust in the professional’s competence, (4) trust as a risk, (5) trust as dynamic, (6) trust as cognitive. A social worker builds trust by listening carefully to clients, considering their interests when choosing their own goals and actions, clearly articulating the goals and premises of social work, and demonstrating that the social worker can contribute meaningfully to the client’s life. In GSW, clients’ distrust and refusal of services are common. Consequently, trust-building often requires plenty of time, creativity and perseverance from the social worker. This is challenged by the fact that there is not always enough time to build trust, trust’s essential nature is not often recognised in the service system, and social workers may lack competence and understanding of the elements of trust and trust-building. In order to meet older adults’ complex needs, it is essential to meet these challenges and place trust at the centre of GSW.

Implementing a Positive Behavior Support Program for Young Children with Autism in Public Agencies: A Social Validity Evaluation from Parents, Practitioners, and Administrators.

Challenging behaviors in young children with autism and intellectual disabilities pose significant barriers to learning and inclusion. The Prevent-Teach-Reinforce for Young Children (PTR-YC) program is an evidence-based intervention that addresses these behaviors according to Positive Behavior Intervention Support principles. It is essential to assess the social validity of an intervention, when implemented into a public service system, to ensure sustainability and relevance to stakeholders. The present study aimed to document the social validity of PTR-YC from the point of view of three key informants: parents, practitioners, and administrators. Sixty-one participants were interviewed about their experience with PTR-YC (9 administrators, 31 practitioners, and 20 families). Semi-structured interviews assessed three fundamental components of social validity (Wolf, 1978): (a) social relevance of intervention goals, (b) social appropriateness of intervention procedures, and (c) social importance of intervention effects. Participants' responses were subjected to thematic analysis. Intervention goals, namely family participation in the clinical process, strategies that focuses on prevention, and teaching alternative adaptive behaviors, were identified as relevant. Participants appreciated the program's clear, structured, and turnkey clinical process, its parent-practitioner collaboration, and its consistency with practices already in place in the field. Positive instrumental outcomes (e.g., knowledge, competencies, self-efficacy) and ultimate outcomes (e.g., decrease in challenging behavior) of the intervention were reported on children, families, and practitioners. This study represents the first in-depth evaluation of the social validity of PTR-YC in specialized public services for autism and demonstrates its appropriateness for universal implementation in this sector.

Research on the Current Status of Pension Models for Individuals with Mental Disorders in China

Objective: By analyzing the existing literature, this paper aims to explore the current situation of the pension model for patients with mental disorders in China and put forward corresponding suggestions for improvement. How: This study analyzes the current situation of the pension model for patients with mental disorders in China by referring to the views of experts and scholars, relevant cases and statistical data through the literature and review of CNKI. Focusing on the existing elderly care service system, policy support and social cognition, this paper reveals the main characteristics and existing problems of the current Chinese elderly care model for people with mental disabilities. By comparing the advanced pension models at home and abroad, this paper puts forward some suggestions on strengthening policy support and improving service system. Results: The research shows that China's existing pension models mainly include family care, institutional pension and community service. The main problems facing: insufficient service supply, shortage of professional talents, social cognition and discrimination. Home care is still the main way, more than 70% of people with mental disorders rely on home care, but face great pressure and challenges; The construction of institutional elderly care and community service systems is gradually developing, but there are still insufficient resources, low service quality, and uneven distribution between urban and rural areas. Policy suggestions: Strengthen the construction and improvement of community support system; Improve professional training to ensure service quality; Use scientific and technological means to assist the elderly and ease the shortage of human resources. It is suggested that we should strengthen the construction of community support system and improve the level of professional service in the future. Conclusion: In China, the mode of nursing care for patients with mental disorders is in the transition period, and family nursing is still the mainstream, but it also faces great challenges. Institutional care and community services have developed, but they are not yet sufficient to replace the role of the family. The future development direction should be multi-dimensional, forming a diversified and three-dimensional elderly care service network.

Research on Equity Policies in Public Education for Learning DisabilitiesTaking China, America and Britain as Examples

With the recovery and development of the global economy, the quality of life worldwide continues to improve, and the demand for public infrastructure such as medical care and education services is becoming more and more vigorous. Medical development and progress have made studying the brain and neurological fields more thorough, and learning disabilities have gradually entered the public eyesight. As a special group, people with learning disabilities are not widely accepted and recognized in the scope of public education. Thus, education must support the development of this virtue cycle through educational fairness policies, as it is a public resource. Based on the existing education policies on learning disabilities in China, the United States, and the United Kingdom, this paper analyzes these policies and puts forward education policy suggestions from four aspects: the education policy formulation system, the education collaborative service system, the education accountability evaluation system, and the education funding service system.Among China, the United Kingdom, and the United States, the first two are based on the improvement of basic policies, focusing on the construction of education collaborative services and education accountability evaluation systems, respectively. The latter focuses on the improvement of education policy.

The decriminalization of illicit drugs in British Columbia: a national evaluation protocol

BackgroundOn January 31st, 2023, the province of British Columbia (BC), Canada, was granted a federal exemption allowing adults (aged 18 +) to possess up to 2.5 g of select illicit drugs. The exemption will be in place for three years (2023–2026), marking the first formal decriminalization of illicit drug policy reform in Canada. BC’s decriminalization initiative is premised on several goals. This project seeks to evaluate each of these goals and their individual and combined contributions to determine the overall success of this policy.MethodsThe following protocol paper provides a detailed outline of a five-year (2022-2027) national evaluation of BC’s decriminalization initiative, as well as the specific objectives, methodologies, and planned analyses for eight interrelated sub-studies that comprise the evaluation. These sub-studies fall under the following five topical areas of research: 1) people who use drugs (PWUD), 2) the police and the criminal justice system, 3) the general public, 4) the health services system, and 5) an economic analysis. Additional research activities may also be explored.ResultsThe overall evaluation and specific sub-study designs were informed by intensive stakeholder engagement. The evaluation was developed in collaboration with an international expert committee who came together to undertake a nominal group technique to decide on the final evaluation design and corresponding logic model. The evaluation will also employ an advisory board and individual sub-study working groups comprised of experts and PWUD who will oversee the development and implementation of the overall evaluation as well as each sub-study.DiscussionThis evaluation will draw on implementation science research practices to evaluate and understand the full impacts of this novel drug policy experiment. Results will be widely disseminated through manuscripts, reports, presentations, and infographics, which will be adapted and tailored for specific audiences. The protocol identifies several anticipated challenges and limitations. This evaluation’s evidence-based findings will be poised to offer pivotal insights that can shape and refine the discourse on drug policy and will serve as a critical resource for understanding the multifaceted impacts of decriminalization.

Cloud Server-based Questionnaire System for Cultural Services in Blue-green Spaces

Parks are important carriers of urban blue-green space and cultural services, which are vital to beautify the city and improve the quality of life of residents. Constructing a questionnaire system for cultural services in blue-green spaces is of great significance for evaluating and studying the supply of regional cultural services and quantifying residents' cultural needs. In this paper, we take Zhengzhou city park as the evaluation object, and based on AliCloud server ECS and WebGIS technology, combined with drone orthophoto and real-life three-dimensional model, we make the questionnaire survey system of blue-green space cultural service to collect residents' social value preference and suggestions for the park. Respondents enter the system through any device with internet access, browse park pictures and profiles, and participate in the online questionnaire survey, and the collected data on residents' value preferences can be used to assess the value of the park's cultural services by methods such as the SolVES model. The system solves the shortcomings such as heavy workload and low response rate of distributing questionnaires in the field. The system integrates a variety of digital technologies and improves the questionnaire survey method, which can effectively improve the efficiency and quality of the questionnaire survey and analyze the problems and deficiencies of the park with the opinions of the respondents, so as to provide the management with references for optimization and standardization, and to promote the enhancement of the quality of cultural services.
