Objectives: Administrative data is commonly used to inform chronic disease prevalence and support health informatics research. This study assessed the validity of coding comorbidity in the International Classification of Diseases, 10th Revision (ICD-10) administrative data. Methods: We analyzed three chart review cohorts (4,008 patients in 2003, 3,045 in 2015, and 9,024 in 2022) in Alberta, Canada. Nurse reviewers assessed the presence of 17 clinical conditions using a consistent protocol. The reviews were linked with administrative data using unique identifiers. We compared the accuracy in coding comorbidity by ICD-10, using chart review data as the reference standard. Results: Our findings showed that the mean difference in prevalence between chart reviews and ICD-10 for these 17 conditions was 2.1% in 2003, 7.6% in 2015, and 6.3% in 2022. Some conditions were relatively stable, such as diabetes (1.9%, 2.1%, and 1.1%) and metastatic cancer (0.3%, 1.1%, and 0.4%). For these 17 conditions, the sensitivity ranged from 39.6-85.1% in 2003, 1.3-85.2% in 2015, and 3.0-89.7% in 2022. The C-statistics for predicting in-hospital mortality using comorbidities by ICD-10 were 0.84 in 2003, 0.81 in 2015, and 0.78 in 2022. Discussion: The under-coding could be primarily due to the increase of hospital patient volumes and the limited time allocated to coders. There is a potential to develop artificial intelligence methods based on electronic health records to support coding practices and improve coding quality. Conclusion: Comorbidities were increasingly under-coded over 20 years. The validity of ICD-10 decreased but remained relatively stable for certain conditions mandated for coding. The under-coding exerted minimal impact on in-hospital mortality prediction.

Background and purpose High intensity training programs for improving technical skills, combined with an increase in the number of matches, impose significant physical strain on players. Virtual reality (VR) and machine learning (ML) technologies have opened up new opportunities to address these problems. However, in particular, there is a lack of research that combines virtual reality and machine learning methods in basketball. This study aims to examine the effectiveness of using virtual reality and machine learning technologies to improve sportsmanship and decision-making skills in basketball players. Material and methods The experiment involved 20 basketball players from Riau, Indonesia, who were divided into two groups: experimental (VR+ML) and control. Measurements were performed using the Stroop test to determine the level of mastery of a certain game function and an observation tool to determine decision-making skills. Results The results of the analysis of the obtained results showed that in the group that was engaged in the use of virtual reality and machine learning (VR+ML) there was a significant improvement in the level of mastery of certain game functions (EF - attention) and decision-making skills (DM) compared to the control group (p < 0.001). Conclusions It was confirmed that the use of virtual reality technologies in combination with machine learning can effectively improve attention, concentration and decision-making ability in basketball athletes. This study offers new understanding of the potential of new technologies in supporting the cognitive development of athletes.

In recent years, the number of initiatives dealing with climate change has increased significantly as human activity releases more and more greenhouse gases into the environment. There is no doubt that the effects of these emissions are numerous and increasingly alarming. Against this background, this paper assumes that climate change requires the engagement of various groups of stakeholders. This engagement is referred to in this paper as ecosystem cooperation for climate action. A feature of ecosystem cooperation is the potential to create a multistakeholder network of new partnerships that can generate innovative solutions to climate change problems. This paper argues that ecosystem collaboration is particularly important for both preventing and responding to climate change. Following a theoretical explanation of the concept of ecosystem collaboration, a case study on climate change and sustainability is presented. This case study highlights best practise examples within a European project entitled “Innovation Laboratories for Climate Actions” (ILCA). Through a consortium of six universities and three research institutes from different European countries, the ILCA project aimed to engage multiple stakeholders in national, regional and local ecosystems to develop innovative solutions to tackle climate change. The project brought together businesses, public administrations, civil society and academia from each country. The findings of this paper emphasise the importance of the ILCA project in tackling climate change through ecosystem collaboration and the establishment of a ‘Climate Innovation Lab’ at the Stefan cel Mare” University in Suceava. Such a lab brings together experts from different fields such as economics, engineering and medicine to find innovative solutions to climate problems. We also emphasise the active role of innovation in helping tourism businesses to adapt to climate change. Innovation and collaboration are crucial to fostering a cooperative environment in relation to climate change mitigation.

Este estudio propone un modelo innovador de turismo sostenible centrado en la promoción y preservación del patrimonio musical gnawa en el desierto de Merzouga, Marruecos. La investigación buscó desarrollar y evaluar un modelo de turismo comunitario que, fundamentado en la música gnawa, fomente la sostenibilidad ambiental y el empoderamiento local. Se planteó la hipótesis de que este modelo al integrar la música gnawa genere ingresos sostenibles para las comunidades, fortalezca la identidad cultural gnawa y reduzca significativamente el impacto ambiental del turismo en la zona, mejorando, así, la calidad de vida de sus habitantes. Para lograr este objetivo, se empleó un enfoque de investigación mixta que combina métodos cuantitativos y cualitativos. Se aplicaron encuestas a turistas y operadores turísticos para recopilar datos cuantitativos, y también se realizaron entrevistas en profundidad a actores clave de la comunidad para obtener información cualitativa. Este enfoque integral permitió un análisis holístico de los efectos y las potencialidades del modelo propuesto.

This study aimed to investigate the German hospitality industry to find out which resilient business strategies operational managers applied during the COVID-19 pandemic and which are considered viable for the future. Drawing on a multiple case study approach, semi-structured online expert interviews were conducted with twelve operational managers from certain sectors of the German hospitality industry. A manual qualitative content analysis was applied to analyse data and to identify resilient business strategies for the COVID-19 pandemic through an iterative coding process. The study results show that operational managers applied diverse resilient business strategies within six areas: grocery shopping, food processing and menu planning, work environment and workplace, guest and customer world, marketing and sales concepts and under prospective perspectives. The business strategies are resilient, as operational managers responded to the crisis in a situation- and organisation-specific manner and implemented transformative business activities. This study provides valuable insights for organisations, managers and practitioners in the different hospitality industry sectors by identifying resilient business strategies in times of crisis. It also highlights what business strategies are considered viable for the future, which could thus serve as a blueprint for the hospitality industry.

The advent of 6G networks will present a pivotal juncture in the evolution of telecommunications, marked by the proliferation of devices, dynamic service requests, and the integration of edge and cloud computing. In response to these transformative shifts, this paper proposes a service and resource discovery architecture as part of service provisioning for the future 6G edge-cloud-continuum. Through the architecture's orchestration and platform components, users will have access to services efficiently and on time. Blockchain underpins trust in this inherently trustless environment, while semantic networking dynamically extracts context from service requests, fostering efficient communication and service delivery. A key innovation lies in dynamic overlay zoning, which not only optimizes resource allocation but also endows our architecture with scalability, adaptability, and resilience. Notably, our architecture excels at predictive capabilities, harnessing learning algorithms to anticipate user and service instance behavior, thereby enhancing network responsiveness and preserving service continuity. This comprehensive architecture paves the way for unparalleled resource optimization, latency reduction, and seamless service delivery, positioning it as an instrumental pillar in the unfolding 6G landscape. Simulation results show that our architecture provides near-optimal timely responses that significantly improve the network's potential, offering scalable and efficient service and resource discovery.

We propose a novel framework for crowdsourced images to determine the likelihood of an image being fake. We use a service-oriented approach to model and represent crowdsourced images uploaded on social media, as image services. Trust may, in some circumstances, be determined by using only the non-functional attributes of an image service, i.e., image metadata. We define intention of changes as a key parameter to ascertain fake image services. A novel framework is proposed to estimate the intention of underlying changes considering change in semantics of an image. Our experiments show high accuracy using a large real dataset.

With the growing demand for network connectivity and diversity of network applications, one primary challenge that network service providers are facing is managing the commitments for Service Level Agreements~(SLAs). Service providers typically monitor SLAs for management tasks such as improving their service quality, customer billing and future network planning. Network service customers, on their side, monitor SLAs to optimize network usage and apply, when required, penalties related to service failures. In future 6G networks, critical network applications such as remote surgery and connected vehicles will require these SLAs to be more dynamic, flexible, and automated to match their diverse requirements on network services. Moreover, these SLAs should be transparent to all stakeholders to address the trustworthiness on network services and service providers required by critical applications. Currently, there is no standardised method to immutably record and audit SLAs, leading to challenges in aspects such as SLA enforcement and accountability -- traits essential for future network applications. This work explores new requirements for future service contracts, that is, on the evolution of SLAs. Based on those new requirements, we propose an end to end layered SLA architecture leveraging Distributed Ledger Technology (DLT) and smart contracts. Our architecture is inheritable by an existing telco-application layered architectural frameworks to support future SLAs. We also discuss some limitations of DLT and smart contracts and provide several directions of future studies.

Crowdsourcing wireless energy services is a novel convenient alternative to charge IoT devices. We demonstrate peer-to-peer wireless energy services sharing between smartphones over a distance. Our demo leverages (1) a service-based technique to share energy services, (2) state-of-the-art power transfer technology over a distance, and (3) a mobile application to enable communication between energy providers and consumers. In addition, our application monitors the charging process between IoT devices to collect a dataset for further analysis. Moreover, in this demo, we compare the peer-to-peer energy transfer between two smartphones using different charging technologies, i.e., cable charging, reveres charging, and wireless charging over a distance. A set of preliminary experiments has been conducted on a real collected dataset to analyze and demonstrate the behavior of the current wireless and traditional charging technologies.

During his NCAA presidency, Myles Brand led novel academic reforms that gained deserved national recognition, but his defense of the educational and academic value of IA should be equally acknowledged since this was, for Brand, the ultimate reason why universities should support intercollegiate athletics (IA) in the first place. In this article, I describe the development of Brand’s view of the educational value of IA that preceded his signature 2006 publication ‘The Role and Value of Intercollegiate Athletics in Universities.’ I then explain Brand’s Integrated View of IA in his 2006 article and focus on his key argumentative strategy: the analogy of the educational value of IA to the educational value of performing arts like music and dance. I contend that Brand did not bring his persuasive analogical argument to its full logical conclusions since IA should contribute to a new academic major in Sport Performance and some of the very character virtues that Brand identified as developed ideally by IA are now recognized as essential academic liberal learning outcomes. I conclude by raising some criticisms of Brand’s view based on the organizational framework and policies of IA that create difficulties for the full realization of its educational value. Nonetheless, at a momentous time in U.S. higher education when university priorities and budgets are under perhaps unprecedented scrutiny, Brand’s insistence that IA must be integrated with the academic mission is more relevant than ever.

Providing uninterrupted response service is of paramount importance for emergency medical services, regardless of the operating scenario. Thus, reliable estimates of the time to the critical condition, under which there will be no available servers to respond the next incoming call, become very useful measures of the system's performance. In this contribution, we develop a key performance indicator by providing an explicit formula for the average time to the shortage condition. Our analytical expression for this average time is a function of the number of parallel servers and the inter-arrival and service times. We assume exponential distributions of times in our analytical expression but for evaluating the mean first-passage time to the critical condition under more realistic scenarios we validate our result through exhaustive simulations with lognormal service time distributions. For this task we have implemented an simulator in $R$. Our results indicate that our analytical formula is an acceptable approximation under any situation of practical interest.

We propose and investigate the concept of commuting service platforms (CSP) that leverage emerging mobility services to provide commuting services and connect directly commuters (employees) and their worksites (employers). By applying the two-sided market analysis framework, we show under what conditions a CSP may present the two-sidedness. Both the monopoly and duopoly CSPs are then analyzed. We showhowthe price allocation, i.e., the prices charged to commuters and worksites, can impact the participation and profit of the CSPs. We also add demand constraints to the duopoly model so that the participation rates ofworksites and employees are (almost) the same. With demand constraints, the competition between the two CSPs becomes less intense in general. Discussions are presented on how the results and findings in this paper may help build CSP in practice and how to develop new, CSP-based travel demand management strategies.

In a world with an ever increasing urbanization, governance is investigating innovative solutions to sustain the society evolution. Internet-of-Things promises huge benefits for cities and the proliferation of smart city deployments demonstrates the common acceptance of IoT as basis for many solutions. The city pilots developments occurred in parallel and with different designs thus creating fragmentation of IoT. The European project SynchroniCity aims to synchronize 8 smart cities to establish a shared environment fostering a self-sustained business growth. In this article we present the collaborative methodology and shared efforts spent towards the creation of a common ecosystem for the development of smart city services. Our design evolves around the concept of "atomic services" that implements a single functional block to be composed for full-fledged smart city services. This creates opportunities for diverse stakeholders to participate to a global smart cities market. The methodology and outcome of our efforts will be followed by 10 new cities globally, thus expanding the market range for IoT stakeholders

Mobile edge computing (MEC) is a promising technique for providing low-latency access to services at the network edge. The services are hosted at various types of edge nodes with both computation and communication capabilities. Due to the heterogeneity of edge node characteristics and user locations, the performance of MEC varies depending on where the service is hosted. In this paper, we consider such a heterogeneous MEC system, and focus on the problem of placing multiple services in the system to maximize the total reward. We show that the problem is NP-hard via reduction from the set cover problem, and propose a deterministic approximation algorithm to solve the problem, which has an approximation ratio that is not worse than $\left(1-e^{-1}\right)/4$. The proposed algorithm is based on two sub-routines that are suitable for small and arbitrarily sized services, respectively. The algorithm is designed using a novel way of partitioning each edge node into multiple slots, where each slot contains one service. The approximation guarantee is obtained via a specialization of the method of conditional expectations, which uses a randomized procedure as an intermediate step. In addition to theoretical guarantees, simulation results also show that the proposed algorithm outperforms other state-of-the-art approaches.

<p class="9"><em>Aim</em>: theoretical substantiation and development of a technique for processing the statistical data of the table tennis match. <em>Material and methods.</em> The study was conducted at the Kharkiv Table Tennis Club "Impulse". A video shoot of a match between two athletes was performed using a regular camera of the smartphone. The statistics of the game were analyzed using the technical techniques and positions of the tennis players at the gaming table, at what distance and in what direction the receptions were performed. <em>Results.</em> The automated processing of information on technical and tactical actions in the competitive activity of athletes from table tennis has been developed, substantiated and implemented in practice. Models of multiple linear regression between the degree of influence of the used technical elements for athlete 1 and the value of the number of points scored per match are made. The high significance of the technical elements of Knack (wins,%) and Scratches (wins,%) in the number of points scored per match is shown. The latest figures were significantly unimportant and with very small coefficients. The regression equation is obtained, which allows you to predict the number of points scored in the party, as well as to identify the most influential elements for the player. <em>Conclusions</em>. The automated calculation of the statistics of video shooting of the match is carried out, where the effectiveness and reliability of the main strikes, which determine the effectiveness of competitive activity in table tennis, is objectively reflected. Displays in the form of diagrams of quantitative assessments of technical and tactical actions in the competitive activity of athletes from table tennis. It is aimed at increasing the effectiveness of tennis players, by identifying their weak and strong points, eliminating them, or vice versa, more frequent use in competitions. The method of processing match statistics in the Excel program is developed, substantiated and implemented in practice. The practical value of the technique is in the availability for most players to apply the proposed method on their own.</p>
