Cross-platform mobile application development is the pressing priority in today’s world and generation. Developers are enforced to either construct the same application numerous times for various OS (operating systems) or accept a low-quality similar solution that trades native speed and accuracy for portability. Flutter is an open-source SDK for developing high-performance and more reliable mobile applications for operating systems like iOS, Android and even windows [1]. Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Student Service App is an automation which will provide duplicate degree, duplicate marksheet, migration, transcript, provisional degree and document verification services to all registered the Universities. It will provide University services related to academics to its registered students via mobile devices on their finger tips for which they have to be present physically at respective places. It has Service oriented architecture so that it will be integrated to the existing ERP (Web Portal) of the different universities.

Tank Information System is a web application which provides comprehensive information about minor irrigation tanks of Telangana State. As part of the program, a web mapping application using Flex and ArcGIS server was developed to make the data available to the public. In course of time as Flex be-came outdated, a migration of the client interface to the latest JavaScript based technologies was carried out. Initially, the Flex based application was migrated to ArcGIS JavaScript API using Dojo Toolkit. Both the client applications used published services from ArcGIS server. To check the migration pattern from proprietary to open source, the JavaScript based ArcGIS application was later migrated to OpenLayers and Dojo Toolkit which used published service from GeoServer. The migration pattern noticed in the study especially emphasizes upon the use of Dojo Toolkit and PostgreSQL database for ArcGIS server so that migration to open source could be performed effortlessly. The current ap-plication provides a case in study which could assist organizations in migrating their proprietary based ArcGIS web applications to open source. Furthermore, the study reveals cost benefits of adopting open source against commercial software's.

One important aspect of ubiquitous environments is to provide users with the possibility to freely move about and continue to interact with the available applications through a variety of interactive devices such as cell phones, PDAs, desktop computers, intelligent watches, or digital television sets. Migratory applications are able to follow the user by sensing changes in the user’s context and adapting to available devices, ideally without interrupting the user experience. However, applications themselves must contain functions to monitor context information, coordinate a migration, handle application adaptation, and interact with the user during the migration process. To make life easier for developers and users of migratory applications, an integrated Migration Service Platform (MSP) is proposed, where all the common migration functions are centralised. The authors show how the platform is realised as middleware that contains a server for the central functions and lightweight client-side running on the end-user devices. The authors show how migratory applications can interact with the platform and thereby do not have to contain migration functions themselves. The authors describe the challenges following the centralisation of a migration platform that can support different types of applications, both games and business applications, implemented with either web-technologies or as component-based applications.

Virtually all UK and US newspapers and the vast majority of regional and even local titles are now represented on the web. Indeed, the Yahoo news and media directory lists no less than 114 UK newspapers online (as of November 1998). Broadcasters from the BBC and Sky downwards, and all the famous news agencies (Press Association, Reuters etc.) also boast comprehensive Internet services. With such an array of sources available, the future of mass access to the Internet, possibly via TV terminals, suggests that more and more people may soon opt for this medium to receive the bulk of their news information. This paper gives an overview of the characteristics of the medium illustrated with examples of how these are being used to both facilitate and enhance the content and dissemination of the news product. These characteristics include hyperlinking to external information sources, providing archive access to past reports, reader interactivity and other features not possible to incorporate into more passive media such as the hardcopy newspaper. From a survey of UK and US news providers it is clear that American newspapers are exploiting the advantages of web information dissemination to a far greater extent than their British counterparts, with the notable exception of The Electronic Telegraph. UK broadcasters, however, generally appear to have adapted better to the new medium, with the BBC rivaling CNN in its depth and extent of news coverage, use of links and other elements.

To meet the demand of the higher precision ratio and recall ratio of service search, a method of Web service discovery is proposed based on ontology evolution and Web service migration. According to the developed cloud service platform and the existed service repository and domain ontology list, a service migration process is proposed which migrate to the cloud platform and implement unified management for Web service. This process effectively achieves that Web services migrate in and out of the cloud platform. In order to realize the self-evolution of domain ontology, an ontology alignment mechanism is designed to automatic extend and replace of ontology concept. This mechanism achieves the integration of different keywords with the same meaning and ensures the consistency of ontology concept. In this paper, the method not only enables efficient service discovery and dynamic service management, but also can achieve high concurrency support of services and supply or billing on demand. The experiments show that the proposed method solves the search problem of low efficiency based on keyword, and it effectively improves the precision ratio and recall ratio of service discovery.

The purpose of the article is to study methods of migration to other environments of information systems previously created in Microsoft Windows in the C# language. These environments either belong to the open class, or were developed directly in Russia. One of the main migration tools is the separation of systems into components. In this case, the transformation tasks of each component are solved separately. Methods of transformation of information systems functioning in an environment based on operating systems, database management tools, web tools, frameworks and libraries are considered. The main directions of preparation of the executive environment, the components of which are included in the register of Russian software, or provide open source codes, are highlighted. Operating systems that meet the given criteria are selected. Basically, these systems are founded on Linux kernel. Methods for configuring the Apache 2 web server and creating a virtual host are defined. A brief assessment of database migration methods was carried out. The issues of correcting the C# source code when changing the operating environment and methods of converting the source text when changing the ways of working with the graphical user interface are considered. The main problems during the transition to the new system and ways to solve them are shown. Taking into account the mandatory code correction required during the migration process and the development of a new graphical user interface, the transition from Windows to Linux is possible at real time-consuming costs. Using existing methods of migrating databases, web services and client applications allows you to complete the migration of information systems based on the C# language into environments that meet the criteria for import substitution.

Purpose The purpose of this paper is to explore the data connection, spatial distribution characteristics and trends in genealogical information. First, it implements a spatial-temporal visualization of the Hakka genealogical information system that makes these individual family pedigree charts appear as one seamless genealogy to family and researchers seeking connections and family history all over the world. Second, this study applies migration analysis by applying big data technologies to Hakka genealogies to investigate the migration patterns of the Hakka ethnic group in Taiwan between 1954 and 2014. This innovative library service enhances the Hakka genealogical migration analysis using big data. Design/methodology/approach The platform is designed for the exchange of genealogical data to be used in big data analysis. This study integrates big data and geographic information systems (GIS) to map the population distribution themes. The general procedure included collecting genealogical big data, geographic encoding, gathering the map information, GIS layer integration and migration map production. Findings The analytical results demonstrate that big data technology is highly appropriate for family migration history analysis, given the increasing volume, velocity and variety of genealogical data. The spatial-temporal visualization of the genealogical research platform can follow family history and migration paths, and dynamically generate roadmaps to simplify the cartographic steps. Practical implications Technology that combines big data and GIS is suitable for performing migration analysis based on genealogy. A web-based application for spatial-temporal genealogical information also demonstrates the contribution of innovative library services. Social implications Big data play a dominant role in library services, and in turn, provide an active library service. These findings indicate that big data technology can provide a suitable tool for improving library services. Originality/value Online genealogy and family trees are linked with large-volume, growing data sets that are complex and have multiple, autonomous sources. The migration analysis using big data has the potential to help genealogy researchers to construct minority ethnic history.

In this paper, Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration, and services. Although organisations adopt Cloud Computing for Web Services, technical and business challenges emerge, including the measurement of Cloud business performance. Organisational Sustainability Modelling (OSM) is a way to measure Cloud business performance quantitatively and accurately. It combines statistical computation and 3D Visualisation to present the Return on Investment arising from the adoption of Cloud Computing by organisations. 3D visualisation simplifies the review process and is a method for Return of Investment (ROI) valuation. Two detailed case studies with SAP and Vodafone are presented, where OSM has analysed the business performance and explained how CCBF offers insights, which are helpful for WS and Grid businesses. Comparisons and discussions between CCBF and other approaches related to WS are presented, where lessons learned are useful for Web Services, Cloud and Grid communities.

The purpose of the study is to show the features of the digital transformation of society and the social sphere, in particular, using digital services and portals for migrants in the social security system. The following tasks have been set to achieve the goal: to find and analyze regulatory and legal documents that regulate and accompany the process of digital transformation of society and social sphere in particular. We proved the need for digital transformation of the social sphere as a way to improve social support for citizens in war conditions, including migrants, to justify the reasons for the sharp increase of Ukrainian migrants in the world and to determine their needs for social protection and social security. We analyzed official web portals, digital services and applications for migrants in terms of providing them with electronic services. The work uses such research methods as content analysis, comparison, synthesis, method of systematization of scientific statements, statistical methods (index method, method of statistical grouping, analysis of dynamic series). We monitored and analyzed social networks in order to obtain and structure data. In particular, the resource approach made it possible to analyze the content of social networks, to analyze the network content focused specifically on the category of migrants, to classify it and to draw conclusions. We conducted web analytics of the official state portals of the Ministry of Social Policy, Ministry of Digital Affairs, Ministry of Reintegration, international and public organizations according to parameters such as information content with useful content, convenient navigation, design, analysis of site visit statistics, etc. The study finds the importance of using digital services and portals for migrants in the social security system. We noted how the demand for digital transformation of the social sphere is a way to improve social support for citizens in war conditions, including migrants. The study analyzes the legal framework, in particular the Strategy of Digital Transformation of the Social Sphere (2020), the Law on the Unified Information System of the Social Sphere (2021), the Concept of Development of the Digital Economy and Society of Ukraine for 2018-2020, etc. The article drew attention to a number of documents of the government and the Ministry of Social Policy regarding the simplification and reduction in time of the process of receiving social benefits and services for citizens, solving many social issues through access to the computer network, the use of digital services, portals and platforms. The study provides data on internal and external migration and substantiates the reasons for the sharp increase in the number of Ukrainian migrants in the world caused by the global migration crisis and the Russian-Ukrainian war. Ukraine recorded the largest number of internally displaced persons in Europe since the end of the Second World War, the eighth place in terms of internally displaced persons in the world. The active phase of the Russian-Ukrainian war since February 2022 became a pushing factor and led to the emergence of a new numerical category of the population - war refugees. Examples of a large number of digital services, portals, applications and with useful information for migrants from Ukraine regarding their faster adaptation and obtaining the necessary e-services in the countries of Poland, the Czech Republic, and Lithuania are given. The article demonstrates the joint efforts and effective steps of the Ministry of Digital Affairs and the Ministry of Social Policy regarding the digital transformation of the social sphere and analyzes the official web portal of the State Migration Service of Ukraine in terms of providing electronic services. Statistics of citizens' appeals confirms the effectiveness of digital electronic services. The article notes Ukraine's global innovations regarding the use of digital documents (e-passports) in the Diya application, which have the same legal force as their physical counterparts - a plastic ID card and a paper passport, despite some limitations. The action continues to develop, generating new applications e-Notary, e-Property, e-Migration, e-IDP, etc. Currently, 14 digital documents and 25 services are available in the application, and more than 90 services are available on the portal. The Ministry of Digital Affairs communicates with countries in Europe, Africa and Asia, which are interested in Ukraine's digital experience. The importance of migration forecasting using new analytical tools of Big Data, Google Trends, statistics of social network platforms (YouTube, Instagram, FB, Twitter) was noted, which can be used to assess and forecast flows of forced emigration of refugees from Ukraine, understanding their needs, intentions and plans. The study expresses a warning that massive waves of migration caused, including the war in Ukraine, could become a destabilizing factor within the European Union community and proves on the example of domestic and foreign experience that global migration processes will require taking interests of migrants into account, as a large and growing community in the world, in the policy of providing electronic services and electronic governance of the host countries. The conclusion formulates that for world balance and security of individual regions and countries, the migration policy should contain digital tools for information and social security of migrants.

Abstract Wetlands are among the most productive ecosystems in the world. They provide numerous beneficial services for people and wildlife. The most important services are improving water quality and wildlife habitats. The complex, dynamic relationships between the organisms inhabiting the wetland environment are called food webs. Both water quality and high levels of nutrients are crucial for improvement of the food web. Many bird species rely on wetlands for food, water and shelter, especially during migration and breeding. The water quality of Choghakhor Wetland was evaluated from April 2010 to March 2011, by measuring some physicochemical parameters and doing benthic macroinvertebrate analysis. Sampling was done in 3 replicates with alternation of 45 days. The resolute was divided into more than 25 identified macroinvertebrate families which belonged to 5 classes and 12 orders. The correlation between biological indices and water quality parameters showed that bioindicators and community indices could be used for the evaluation of water quality in this wetland. The water quality of Choghakhor Wetland was classified as average or in the severe pollution class, according to these indices. It can be concluded that bird migration is at risk due to the decline in the overall health of the Choghakhor Wetland ecosystem.

CNAF is the national center of INFN (Italian National Institute for Nuclear Physics) for IT technology services. The Tier-1 data center operated at CNAF offers computing and storage resources to scientific communities as those working on the four experiments of LHC (Large Hadron Collider) at CERN and other 30 experiments in which INFN is involved. In past years, monitoring and alerting services for Tier-1 resources were performed with several software, such as LEMON (developed at CERN and customized on the char-acteristics of datacenters managing scientific data), Nagios (especially used for alerting purposes) and a system based on Graphite database and other ad-hoc developed services and web pages. By 2015, a task force has been organized with the purpose of defining and deploying a common infrastructure (based on Sensu, InfluxDB and Grafana) to be exploited by the different CNAF depart-ments. Once the new infrastructure was deployed, a major task was then to adapt the whole monitoring and alerting services. We are going to present the steps that the Tier-1 group followed in order to accomplish a full migration, that is now completed with all the new services in production. In particular we will show the monitoring sensors and alerting checks redesign to adapt them to the infrastructure base on the Sensu software, the web dashboards creation for data presentation, the porting of historical data from LEMON/Graphite to InfluxDB.

Abstract In linear food chains, resource and predator control produce positive and negative correlations, respectively, between biomass at adjacent trophic levels. These simple relationships become more complex in food webs that contain alternative food chains of unequal lengths. We have used a “minimum” model for the microbial part of the pelagic food web that has three such food chains connecting free mineral nutrients to copepods: via diatoms, autotrophic flagellates, and heterotrophic bacteria. Trophic cascades from copepods strongly modulates the balance between the three pathways and, therefore, the functionality of the microbial food web in services such as food production for higher trophic levels, DOM degradation, and ocean carbon sequestration. The result is a theoretical framework able to explain, not only apparent conflicts in Arctic mesocosm experiments, but also biogeochemical features of the Mediterranean. Here, the fundamental difference between Arctic and Mediterranean microbial food webs is the way they are predator driven by seasonal migration of large copepods in the Arctic, but resource driven due to the anti-estuarine circulation in the Mediterranean. In this framework, global change effects on microbial ecosystem functions are more like to come indirectly through changes in these drivers than through direct temperature effects on the microbes.

Context-awareness has become a key issue in Human-Computer Interaction(HCI) to provide better user experience under multi-device and multi-modal environment. With this intuition, we have proposed a web service based framework, which associates interactions with services, and provided service selection mechanism using context knowledge to achieve smart interaction migration [1]. A fundamental problem of such a service-oriented framework for interaction migration is to design an effective while scalable algorithm for service selection. In this paper, we propose a service selection algorithm considering not only context information and user preferences but also inter-service relations such as relative location. Our algorithm detects interaction hot spots within user active scope and presents the best service combination based on evaluation of interaction effectiveness. We also conduct simulation and the results illustrate that our algorithm is effective and scalable for interaction service selection.

Abstract Objective Develop and test web services to retrieve and identify the most precise ICD-10-CM code(s) for a given clinical encounter. Facilitate creation of user interfaces that 1) provide an initial shortlist of candidate codes, ideally visible on a single screen; and 2) enable code refinement. Materials and Methods To satisfy our high-level use cases, the analysis and design process involved reviewing available maps and crosswalks, designing the rule adjudication framework, determining necessary metadata, retrieving related codes, and iteratively improving the code refinement algorithm. Results The Partners ICD-10-CM Search and Mapping Services (PI-10 Services) are SOAP web services written using Microsoft's.NET 4.0 Framework, Windows Communications Framework, and SQL Server 2012. The services cover 96% of the Partners problem list subset of SNOMED CT codes that map to ICD-10-CM codes and can return up to 76% of the 69 823 billable ICD-10-CM codes prior to creation of custom mapping rules. Discussion We consider ways to increase 1) the coverage ratio of the Partners problem list subset of SNOMED CT codes and 2) the upper bound of returnable ICD-10-CM codes by creating custom mapping rules. Future work will investigate the utility of the transitive closure of SNOMED CT codes and other methods to assist in custom rule creation and, ultimately, to provide more complete coverage of ICD-10-CM codes. Conclusions ICD-10-CM will be easier for clinicians to manage if applications display short lists of candidate codes from which clinicians can subsequently select a code for further refinement. The PI-10 Services support ICD-10 migration by implementing this paradigm and enabling users to consistently and accurately find the best ICD-10-CM code(s) without translation from ICD-9-CM.

Problem setting. In the XXI century almost all aspects of human life are covered by the processes of scientific and technological progress. The sphere of law has not been spared from these processes: thanks to information technologies, certain legal services have become more accessible and convenient. In Ukraine, this was manifested not only in the creation of electronic versions of national legislation and various electronic registers, but also in the provision of administrative services through the relevant services. Consular activities involve the provision of services. Amendments to the procedure for the provision of such administrative services and the provision of such services in electronic form can accelerate the process of digitalization of Ukraine, as well as unload the work of diplomatic institutions and reduce corruption risks. Analysis of recent researches and publications. In the national legal literature in recent years, much attention has been paid to e-government (Kravets R., Kuzhda T., Romaniv T.), while almost no attention is paid to the analysis of the state of implementation of electronic services (Solomko Y.), in particular electronic visa services (Kolomiets G., Makhoniuk O., Mulska O.), which determines the relevance and practical significance of this study. Target of research is to investigate the introduction of electronic services for foreign citizens to obtain a visa to enter or transit through the territory of Ukraine, as well as forecasting the prospects of using electronic visas in Ukraine based on the analysis of foreign experience of using this type of visa. Article’s main body. For the implementation of visa services, the Internet acts as a special platform for submitting, processing and, in some cases, providing a ready-made document granting the right to enter the country. This may be a special government website designed to process visa applications of foreigners or a special web application for migration issues. The use of the e-visa concept has been successfully tested in foreign countries and in the EU. It is mainly used by the states with strict immigration policies in order to facilitate and systematize the work of their diplomatic, consular and migration institutions, an electronic authorization system was created. Conclusions and prospects for the development. As a result of the study of the phenomenon of e-diplomacy, analysis of the practice of using electronic services for the provision of administrative services by diplomatic and consular institutions, analysis of the legislation of the countries with advanced e-visas, the state of implementation of e-visas in Ukraine was assessed and the prospects for their development were determined. The steps of the state in this direction are part of a large reform of digitalization of the country, the implementation of which will improve the image of Ukraine in the world, make our country attractive for tourists, as well as optimize the visa issuance procedure, relieving the workload of diplomatic and consular missions, authorized persons for processing visa applications and the Migration Service of Ukraine. The introduction of the e-visa institute as an element of digital diplomacy provides an opportunity for quick bilateral contact and communication, and thus contributes to the achievement of the goals set in the Strategy of State Migration Policy of Ukraine until 2025.

The evolution of Information Systems implies new applications and the need to migrate the data from a previous application to a new one. At the same time, some organizations may need to replicate data from one technology to another one, in order to have backup systems and have a flexible load balanced strategies. The maximal uniform distribution of the load across closer and number of simpler nodes can help managing and providing the big data and large workloads which are more easy to handle. The ultimate goal is to balance the load through cloud and make internet less cloud defendant by having data available closer to the user end. One of the most challenging steps required to deploy an application infrastructure in the cloud involves the physics of moving data into and out of the cloud. Amazon Web Services (AWS) provides a number of services for moving data, and each solution offers various levels of speed, security, cost, and performance. This stems from the fact that almost all the typical distributed storage systems only provide data-amount-oriented balancing mechanisms without considering the different access load of data. To eliminate the system bottlenecks and optimize the resource utilization, there is a demand for such distributed storage systems to employ a workload balancing and adaptive resource management framework. We propose a framework of Enhanced replication scheduling algorithm which balances the replicated data to be balanced and to handle the overload data integration by data migration concept which gives more data efficiency and improved performance during migration of replicated data. For handling of data migration, we propose Ant Colony Algorithm which gives a safe data migration from one end to the other. This will improve the efficiency, Cost and takes less duration for the data to migrated and to be equally balanced.

Grid computing has become one of the most important research topics that appeared in the field of computing in the last years. Simultaneously, we have noticed the growing popularity of new Web-based technologies which allow us to create application-oriented Grid middleware services providing capabilities required for dynamic resource and job management, monitoring, security, etc. Consequently, end users are able to get easier access to geographically distributed resources. In this paper we present the results of our experiments with the Grid(Lab) Resource Management System (GRMS), which acts on behalf of end users and controls their computations efficiently using distributed heterogeneous resources. We show how resource matching techniques used within GRMS can be improved by the use of a job migration based rescheduling policy. The main aim of this policy is to shorten job pending times and reduce machine overloads. The influence of this method on application performance and resource utilization is studied in detail and compared with two other simple policies.

The DINA system (“DIgital information system for NAtural history data”, https://dina-project.net) consists of several web-based services that fulfill specific tasks. Most of the existing services are covering single core features in the collection management system and can be used either as integrated components in the DINA environment, or as stand-alone services. In this presentation single services will be highlighted as they represent technically interesting approaches and practical solutions for daily challenges in collection management, data curation and migration workflows. The focus will be on the following topics: (1) a generic reporting and label printing service, (2) practical decisions on taxonomic references in collection data and (3) the generic management and referencing of related research data and metadata: Reporting as presented in this context is defined as an extraction and subsequent compilation of information from the collection management system rather than just summarizing statistics. With this quite broad understanding of the term the DINA Reports & Labels Service (Museum für Naturkunde Berlin 2018) can assist in several different collection workflows such as generating labels, barcodes, specimen lists, vouchers, paper loan forms etc. As it is based on customizable HTML templates, it can be even used for creating customized web forms for any kind of interaction (e.g. annotations). Many collection management systems try to cope with taxonomic issues, because in practice taxonomy is used not only for determinations, but also for organizing the collections and categorizing storage units (e.g. “Coleoptera hall”). Addressing taxonomic challenges in a collection management system can slow down development and add complexity for the users. The DINA system uncouples these issues in a simple taxonomic service for the sole assignment of names to specimens, for example determinations. This draws a clear line between collection management and taxonomic research, of which the latter can be supported in a separate service. While the digitization of collection data and workflows proceeds, linking related data is essential for data management and enrichment. In many institutions research data is disconnected from the collection specimen data because the type and structure cannot be easily included in the collection management databases. With the DINA Generic Data Module (Museum für Naturkunde Berlin 2017) a service exists that allows for attaching any relational data structures to the DINA system. It can also be used as a standalone service that accommodates structured data within a DINA compliant interface for data management.

Abstract As demographic shifts are occurring in many urban cities in the USA, human service organisations (HSOs) are challenged to provide services conducive to the local region’s demographic profile. In order to create urban societies where immigrant populations can thrive, prosper and become productive citizens, it is important to understand the human service landscape of the region. As part of a larger community-based participatory research project, this study explores human services geared towards the New American population in a midwestern region of the USA. This includes human service access and utilisation, as well as barriers and facilitators of human service provision and delivery, among the growing New American population. Based on the responses received from a web-based survey, in-depth interviews and focus group discussions, this study (N = 165) uses a human service equity lens to situate HSOs and community capacity at the centre of migration and human service research. Knowledge gained from this study will help promote improved service delivery systems; address the quality of direct services; and improve accessibility, accountability and service coordination among HSOs to serve the diverse New American population, which can be replicated to many other similar urban regions across the globe.

In the era of the game publishing industry, MAJAMOJO collaborates with game developers in developing game server infrastructure in Indonesia, by realizing the adoption of cloud computing using the Roadmap for Cloud Computing Adaption (ROCCA) method. Cloud computing implementation by following 5 stages of modification of the ROCCA adoption model, namely the analysis, design, adoption, migration, and management stages. By using Amazon Web Service (AWS) Cloud Service (CSP) services. Cloud computing adoption is carried out by developing game server infrastructure as connectivity between the client and the game server. The analysis is carried out by collecting data and interviews from speakers, in the design of the cloud computing technology to be used, the selection of the technology is based on the results of the analysis stage, then the adoption process prepares the cloud infrastructure to be built, based on software selection and setting up servers with recommended specifications, then migration is the core of the cloud computing adoption process, Where the process transfers the system from the physical server to the virtual server, new management will be executed if the adoption and migration process has been completed with the Game Server and Game Client connectivity indicators running normally. With the application of cloud computing based on the characteristics of the cloud itself, it is flexible, scalable, and safe to access over the internet.

Background: Forced migration of humans as a result of conflict continues to be a global problem. Many of the refugees displaced and made vulnerable by conflict induced forced migration are older adults. These older adults may lose their social networks and support as a result of the conflicts leading to migration and be unable to recreate them, making them more vulnerable. This review aims to describe the social network and support situation of older adults in refugee situation as presented in global literature.
Methods/Design: The five steps of Arksey and O’Malley’s (2005) framework to search multiple databases from inception till June 2021 will be followed. MeSH terms and keywords, e.g., “older refugees”, “refugees”, and “social network”, “social support”, will be adopted for the following databases: SocINDEX, PsychINFO, Social Work Abstracts, Sociology Abstracts, Social Services Abstracts, Web of Science and/or Scopus, Canadian electronic library. Citations will be screened (title/abstract and full text) using predefined inclusion and exclusion criteria. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) will be used to describe the process of data inclusion and exclusion.
Discussion: This review will reveal gaps in the provision of social support to older refugees and inform policy development for the improvement of support to older refugees.

Currently, organizations face the need to create scalable applications in an agile way that impacts new forms of production and business organization. The traditional monolithic architecture no longer meets the needs of scalability and rapid development. The efficiency and optimization of human and technological resources prevail; this is why companies must adopt new technologies and business strategies. However, the implementation of microservices still encounters several challenges, such as the consumption of time and computational resources, scalability, orchestration, organization problems, and several further technical complications. Although there are procedures that facilitate the migration from a monolithic architecture to micro-services, none of them accurately quantifies performance differences. The current study aims primarily to analyze some related work that evaluated both architectures. Furthermore, we assess the performance and relationship between different variables of an application that runs in a monolithic structure compared to one of the micro-services. With this, the state-of-the-art review was initially conducted, which confirms the interest of the industry. Subsequently, two different scenarios were evaluated: the first one comprises a web application based on a monolithic architecture that operates on a virtual server with KVM, and the second one demonstrates the same web application based on a microservice architecture, but it runs in containers. Both situations were exposed to stress tests of similar characteristics and with the same hardware resources. For their validation, we applied the non-parametric regression mathematical model to explain the dependency relationship between the performance variables. The results provided a quantitative technical interpretation with precision and reliability, which can be applied to similar issues.

Mental illnesses in adolescence and young adulthood are steadily increasing. Thus, mental disorders represent an individual and societal challenge and an enormous health economic burden, creating an urgent need for research and action. Mental health problems are omnipresent in the life of young people and the internet is the first resource, which helps them to understand their situation. Young people with migration background often have more difficulties accessing health care services. Digital technologies offer an ideal opportunity for a low-threshold platform that addresses the needs of young people. The current project “GeKo:mental” aims to design a multilingual website for Cologne-based adolescents and young adults that will enable them to obtain comprehensive information about mental illness and health, treatment options and first contact points. To design this website, this study aims to find out what kind of health information is needed and how it should best be presented. Nine focus group discussions with adolescents and young adults with and without migration background (N = 68) were conducted; the focus group discussions took place at schools, in an association for social youth work and in an cultural association, which is linked to a mosque in Cologne, Germany. A qualitative content analysis was conducted on the gathered material. The participants reported concrete challenges and needs. The results will form the basis for the development and design of a website.

Regional capitals are an important category of cities in the South of European Russia, where more than a quarter (25.6 %) of the population of the macroregion lives and a significant demographic potential of the region is concentrated. The south of European Russia includes regions with natural population growth which are rare for modern Russia, regions and capitals with high rates of migration growth, as well as territories with an unfavorable demographic situation. To study territories with such a differentiated multidimensional demographic situation, geoinformation technologies were used to consolidate statistical data from various sources, conduct spatial analysis, model and visualize the processes under study. The realization of this request is possible with the use of atlas information systems (AIS), which are actively used in various subject areas, including the study of socio-economic and demographic processes. As part of the research, we have developed an atlas information system “Regional Capitals of the South of European Russia”, consisting of 2 main blocks: a structural block includes a basic GIS platform, a cartographic framework, a geodata database and a modeling and visualization unit responsible for the preparation of cartographic and visual models. AIS contains 6 thematic sections: ethnodemographic and migration processes (“Population size”, “Demographic indicators”, “Migration indicators”, “Ethnic structure of the population”), “Covid-19” (contains indicators for the sick, deceased, cured of coronavirus infection, natural population growth), “Big Data (Big Data)” consolidating indicators on the real estate market and the urban environment quality index as important factors in the formation of the demographic and migration situation. This makes it possible to conduct modeling, thematic mapping, creation of various visual plots for comprehensive complex spatial analysis. It allows to increase the level of analytics in the process of making economically determined management decisions in the regional capitals of Southern European Russia. Additionally, the possibility of integrating AIS with Web services is described.

1. Purpose: One of the consequences of the COVID-19 pandemic period was the migration of educational centers from face-to-face learning to e-learning. Most centers adapted their educational services and technological resources so that the students could attend the courses online and the teachers (and the rest of the staff) could telework. So, technology departments have become critical in educational services and need to adapt their processes. The ITIL (Information Technology Infrastructure Library) standard guides companies for this transformation. If educational centers are involved in digital transformation, the question to solve is the following: How far are the processes used in the technology departments of educational centers from the ITIL standard adopted in the information technology industry? The purpose of this research was to investigate whether technology departments have implemented the necessary processes. 2. Methods. The research was conducted by means of an online form sent to educational organizations to gather information about their technological processes. The responses collected from the web forms were statistically analyzed. 3. Results and conclusion. The main finding in this paper was that technology departments in educational centers have yet to adopt the processes required for an intensive online service, demonstrating a weakness in educational institutions.

ObjectiveTo identify factors associated with accessing and utilisation of healthcare and provision of health services in slums.DesignA scoping review incorporating a conceptual framework for configuring reported factors.Data sourcesMEDLINE, Embase, CINAHL, Web of Science and the Cochrane Library were searched from their inception to December 2021 using slum-related terms.Eligibility criteriaEmpirical studies of all designs reporting relevant factors in slums in low and middle-income countries.Data extraction and synthesisStudies were categorised and data were charted according to a preliminary conceptual framework refined by emerging findings. Results were tabulated and narratively summarised.ResultsOf the 15 469 records retrieved from all years, 4368 records dated between 2016 and 2021 were screened by two independent reviewers and 111 studies were included. The majority (63 studies, 57%) were conducted in Asia, predominantly in India. In total, 104 studies examined healthcare access and utilisation from slum residents’ perspective while only 10 studies explored provision of health services from providers/planners’ perspective (three studies included both). A multitude of factors are associated with accessing, using and providing healthcare in slums, including recent migration to slums; knowledge, perception and past experience of illness, healthcare needs and health services; financial constraint and competing priorities between health and making a living; lacking social support; unfavourable physical environment and locality; sociocultural expectations and stigma; lack of official recognition; and existing problems in the health system.ConclusionThe scoping review identified a significant body of recent literature reporting factors associated with accessing, utilisation and provision of healthcare services in slums. We classified the diverse factors under seven broad categories. The findings can inform a holistic approach to improving health services in slums by tackling barriers at different levels, taking into account local context and geospatial features of individual slums.Systematic review registration numberhttps://osf.io/694t2.

The study of land-use and land-cover change (LULCC) and their impact on ecosystem services (ESs) is vital for Nepal, where the majority of people are dependent on agriculture and services related to the ecosystem. In this context, this paper aims to appraise the empirical studies on land-use and land-cover changes and their impact on ecosystem services in Nepal Himalaya. The study acquired studies from Web of Science and Google Scholar for systematic review. Altogether, 90 scientific studies, including 64 on land use and land cover and 26 on ecosystem services, published between 1986 and 2020 focusing Nepal, were assessed. The results show that there were continual changes in land-cover and land-use types in Nepal, as well as in the pace of development due to natural, anthropogenic, and policy factors. According to the national land-cover scenario, forests tended to increase, whereas agricultural land gradually decreased in recent years, with some of the available agricultural land even being abandoned. The scenario of the agricultural land in the Karnali river basin was different from those of the land in the Koshi and Gandaki basins. In the mid-twentieth century, the expansion of agricultural land and massive deforestation were observed, mainly in the Tarai region. Development works, urbanization, and the rural–urban migration led to the gradual decrease in and abandonment of the available agricultural land in recent decades. Further, this overall scenario has determined in provision of ESs. Forests have the highest value of ES, and community forests have played a vital role in their restoration. The concept of payment for ESs has greatly supported socio-economic development and ecosystem conservation. However, the formulation and implementation of effective landscape planning with suitable policies and enforcement mechanisms is essential to balance the negative impact of LULC on the sustained management of ecosystems and their associated services.

Purpose Refugee and asylum-seeking women are particularly vulnerable to experiencing mental health difficulties during the perinatal period, with social factors compounding these experiences. Research is limited into the mental health needs of perinatal women who are refugees or seeking asylum. The purpose of this paper is to examine the best available international evidence on this topic and to discuss the findings with relevance to the UK context. Design/methodology/approach A modified population, intervention, comparison, outcome was used to formulate the research question and search strategy. Databases searched were: cumulative index of nursing and allied health literature, Medline, PsychINFO, Web of Science and Scopus. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-analysis framework, results were screened against an inclusion and exclusion criteria. Each study underwent a quality assessment in which they were appraised using the mixed methods appraisal tool. Findings Eight papers were retrieved, and a thematic analysis was conducted. Two major themes were identified: mental health needs and social influences. Refugees and asylum seekers are likely to have experienced trauma as reasons for migration. Post-migration stressors, including hostility and dispersal from social networks, lead to cumulative trauma. These each add to the mental health needs of perinatal refugee and asylum-seeking women that cannot be ignored by policymakers, health and social care services or professionals. Originality/value Refugee and asylum-seeking women are particularly vulnerable to mental health difficulties in the perinatal period. Stressors accumulated pre-, during and post-migration to the host country exacerbate mental distress. In the UK, the treatment of this population may be detrimental to their mental health, prompting the need for greater critical awareness of the socioecological environment that refugee or asylum-seeking women experience.

The CERN IT Storage group operates multiple distributed storage systems to support all CERN data storage requirements: the physics data generated by LHC and non-LHC experiments; object and file storage for infrastructure services; block storage for the CERN cloud system; filesystems for general use and specialized HPC clusters; content distribution filesystem for software distribution and condition databases; and sync&share cloud storage for end-user files. The total integrated capacity of these systems exceeds 0.6 Exabyte. Large-scale experiment data taking has been supported by EOS and CASTOR for the last 10+ years. Particular highlights for 2018 include the special HeavyIon run which was the last part of the LHC Run2 Programme: the IT storage systems sustained over 10GB/s to flawlessly collect and archive more than 13 PB of data in a single month. While the tape archival continues to be handled by CASTOR, the effort to migrate the current experiment workflows to the new CERN Tape Archive system (CTA) is underway. Ceph infrastructure has operated for more than 5 years to provide block storage to CERN IT private OpenStack cloud, a shared filesystem (CephFS) to HPC clusters and NFS storage to replace commercial Filers. S3 service was introduced in 2018, following increased user requirements for S3-compatible object storage from physics experiments and IT use-cases. Since its introduction in 2014N, CERNBox has become a ubiquitous cloud storage interface for all CERN user groups: physicists, engineers and administration. CERNBox provides easy access to multi-petabyte data stores from a multitude of mobile and desktop devices and all mainstream, modern operating systems (Linux, Windows, macOS, Android, iOS). CERNBox provides synchronized storage for end-user’s devices as well as easy sharing for individual users and e-groups. CERNBox has also become a storage platform to host online applications to process the data such as SWAN (Service for Web-based Analysis) as well as file editors such as Collabora Online, Only Office, Draw.IO and more. An increasing number of online applications in the Windows infrastructure uses CIFS/SMB access to CERNBox files. CVMFS provides software repositories for all experiments across the WLCG infrastructure and has recently been optimized to efficiently handle nightlybuilds. While AFS continues to provide general-purpose filesystem for internal CERN users, especially as $HOME login area on central computing infrastructure, the migration of project and web spaces has significantly advanced. In this paper, we report on the experiences from the last year of LHC RUN2 data taking and evolution of our services in the past year.. We will highlight upcoming changes and future improvements and challenges.

Adolescent girls and young women are an overlooked group within conflict- or disaster-affected populations, and their sexual and reproductive health (SRH) needs are often neglected. Existing evidence shows that forced migration and human mobility make girls and women more vulnerable to poor SRH outcomes such as high risk sexual behaviors, lack of contraception use, STIs and HIV/AIDS. We performed a systematic literature review to explore knowledge, experiences and access to SRH services in this population group across the African continent. Two databases (PubMed and Web of Science) were searched and from 896 identified publications, 15 peer-reviewed articles published in English met the inclusion criteria for this review. These consisted of eight applied qualitative, five quantitative and two mixed-method study designs. The quality of the studies was evaluated by the mixed-methods appraisal tool (MMAT) using scores in percentages (0–100%). Available evidence indicates that knowledge of young women and girls regarding contraceptive methods, STIs and HIV/AIDS are limited. This population group often experiences gender-based and sexual violence and abuse. The access and availability of SRH services are often limited due to distances, costs and stigma. This review demonstrates that there is still a dearth of peer-reviewed literature on SRH related aspects among refugee, migrant and displaced girls and young women in Africa. The data disaggregation by sex and age should be emphasized for future research in this field.

Digital discourse, often referred to as computer-mediated communication, has revolutionized communication practices since the advent of the personal computer (Crystal, 2011), with ever-growing effects, as smart devices proliferate in every aspect of twenty-first-century human existence. Linguists in the francophone world first took note of these new digital interactional practices in the 1980s with the onset of conversation via Minitel (Levy, 1993), a French-born service that consisted of a computer terminal that connected via telephone lines to remote services like chatrooms, interactive games, and purchasing platforms, years before most Americans had ever heard of the world wide web (Mailland, 2017). Minitel terminals remained functional some 30 years later; the service was ultimately decommissioned in 2012 on account of outdated modems, an inability to support advancements in graphics and the earlier mass migration (in France and beyond) to the present-day internet (Mailland, 2017). But the introduction of virtual interactional spaces – in the francophone world and beyond – had marked the beginning of a new linguistic trend in which users found themselves regularly engaged in the production of written language infused with vernacular tendencies.

The development of information and communication technologies today is one of the main drivers of tourism progress as a global social phenomenon. Against this background, the migration of geographic information technologies to the Internet and expanding of their practical use (including in the tourism sector) in the form of cartographic and geographic information services is logical. However, the introduction of technologies is constrained by their low availability (financial, intellectual, etc.) for the consumer. The paper is devoted to the development of the technological basis for increasing the availability of creating and using tourist geoportals and interactive web-maps (for example, the Moscow region). The basis of the technology is the mechanism of improved educational and scientific activity of students of the higher education system in the direction of tourism through innovative project activities. The software framework was made by the free “Open Source” products: Leaflet, PostgreSQL/PostGIS, HTML and HTML5, CSS3 and JavaScript. Design was carried out in 5 stages. The result was a tourist geoportal in the Moscow region. The main research methods were: modeling, comparative and descriptive methods, analysis and synthesis, analogies, etc.; the main research approaches were systemic, integrated, geographical and situational ones.

Abstract Marine biodiversity and ecosystem functioning – including seaweed communities – in the territorial waters of the UK and its Overseas Territories are facing unprecedented pressures. Key stressors are changes in ecosystem functioning due to biodiversity loss caused by ocean warming (species replacement and migration, e.g. affecting kelp forests), sea level rise (e.g. loss of habitats including salt marshes), plastic pollution (e.g. entanglement and ingestion), alien species with increasing numbers of alien seaweeds (e.g. outcompeting native species and parasite transmission), overexploitation (e.g. loss of energy supply further up the food web), habitat destruction (e.g. loss of nursery areas for commercially important species) and ocean acidification (e.g. skeletal weakening of ecosystem engineers including coralline algal beds). These stressors are currently affecting biodiversity, and their impact can be projected for the future. All stressors may act alone or in synergy. Marine biodiversity provides crucial goods and services. Climate change and biodiversity loss pose new challenges for legislation. In particular, there are implications of climate change for the designation and management of Marine Protected Areas and natural carbon storage by marine systems to help control the global climate system. The UK currently has legal obligations to protect biodiversity under international and European law.

User information support is among the functions of academic libraries. The authors attempt to reveal the potential of this activity vector. They characterize in brief the academic libraries’ performance in the external environment, reveal the changes in digital environment and social demands due to advancing IT: using Open Access, Semantic Web, Big Data and Data Analytics technologies in handling science data, the most recent phenomenon of Data Science, etc. The authors argue that the origins of further transformations will be the migration of communications, including scientific ones, toward the cyberspace, preferential generation and use of e-documents, supercomputer technologies, cloud computing, end-to-end technologies, multimodal interaction, science IT-services, etc. These transformations have been changing primarily the academic library users – who are high-end professionals with increasingly complex and unique information needs which the libraries are supposed to satisfy. This purpose can be fulfilled through prompt knowledge update, processing enormous flows of fast-aging information, delivery of resulting knowledge, comparative analytical data, range of solutions, etc. The current trends in the information support in academic libraries are discussed based on the information tail content analysis and observations: support of grant management, support of expert examination of academic papers, generation of analytical bibliographies, and organization of scientific communications, researchers, papers and ideas promotion in the global information space. In the professional literature, the information needs to determine the user services vectors for scientific libraries and their bibliographers are revealed, namely, IT-services support, virtual learning laboratory, e-science, knowledge and learning commons, library involvement in scientific data curation, expert analysis of generated information and preliminary quality appraisal, recommending publications and publishers to researchers, related administration and mediation, visual analytics, etc. The primary role of bibliographers in the libraries of the future is emphasized.

The Thesis is about an architecture model for a Distributed Virtualization System, which could expand a virtual execution environment from a single physical machine to several nodes of a cluster. With current virtualization technologies, computing power and resource usage of Virtual Machines (or Containers) are limited to the physical machine where they run. To deliver high levels of performance and scalability, cloud applications are usually partitioned in several Virtual Machines (or Containers) located on different nodes of a virtualization cluster. Developers often use that processing model because the same instance of the operating system is not available on each node where their components run. The proposed architecture model is suitable for new trends in software development because it is inherently distributed. It combines and integrates Virtualization and Distributed Operating Systems technologies with the benefits of both worlds, providing the same isolated instance of a Virtual Operating System on each cluster node. Although it requires the introduction of changes in existing operating systems, thousands of legacy applications would not require modifications to obtain their benefits. A Distributed Virtualization System is suitable to deliver high-performance cloud services with provider-class features, such as high-availability, replication, migration, and load balancing. Furthermore, it is able to concurrently run several isolated instances of different guest Virtual Operating Systems, allocating a subset of nodes for each instance and sharing nodes between them. Currently, a prototype is running on a cluster of commodity hardware provided with two kinds of Virtual Operating Systems tailored for internet services (web server) as a proof of concept.

The influx of seasonal migrants has a significant impact on public services in destination places and may reshape the spatial accessibility and equity patterns of park green space (PGS). However, the two-step floating catchment area (2SFCA) method and its extended forms neglect discrepancies between the travel behaviors of seasonal migrants and native residents and thus fail to delineate variations in PGS accessibility and equity in areas with seasonal migrants. To avoid this issue, this study drew on the case of Sanya, a city with large numbers of Houniao, who are primarily retirees leading seasonal migration between the north and the south of China. A multi-group, multi-mode Gaussian-based 2SFCA method was also proposed to evaluate the PGS accessibility and equity before and after the Houniao influx. The method considered the changes in the COVID-19 restrictions from a refined perspective, with fine-scale residential areas being the research units and travel time requested from the web map application programming interface. The results showed that most residential areas were found to have relatively low PGS accessibility and equity levels, except for those in the south-central and southwestern urban areas of Sanya. Both the Houniao influx and lifted COVID-19 restrictions affected the spatial patterns of PGS accessibility and equity. PGS accessibility and equity were decreased by the Houniao influx, whereas walking and public transport within a few residential areas outside Houniao gathering spots improved. This study can serve as a basis for the reasonable planning of PGS and other public services in cities receiving seasonal migrants, such as Sanya.

Purpose: The purpose of the study was to understand what the Nigerian graduates are passing through, most especially graduate of library and information science programme of Nigerian tertiary institutions.
Findings: The statistics of unemployed graduates in Nigeria as at 2011 showed that a disheartening figure of 42.7 million with over 1,8 million graduates churned out of our higher institutions yearly. It was further revealed that the unemployment rate in Nigeria stood at 38 percent in 2013 with further increase expected in succeeding years. The slow rate of economic growth and undeveloped private sector, faulty manpower planning, high expectations of the fresh graduate attitude towards some types of jobs, recruitments, the quest for higher education, inadequate educational curricular, immobility of labour, the long period of initial unemployment among graduates of higher institution, use of capital intensive technology, wide rural-urban migration
Conclusion: It is evident that entrepreneurship education is important for Library and Information Science students in higher institution of learning. The training of Library and Information Science students must reflect the 21st century development in the field which is influenced by the emergence of Information Technology, hence, Library and Information Science students must have computer proficiency, familiarity with metadata, database management and application, web development and design, knowledge of electronic resources and services

The paper summarizes a semantic association evaluation and reasoning method, utilising domain and problem solving ontologies. The method combines algorithms for data aggregation and logic reasoning utilising concrete financial data. As an outcome method supports suspicious behaviour recognition of money loundering schemes. These scenarios and schemes are implemented by the analysts using ontology-based constructs. Provided tools cover all stages of data processing starting from structural data extraction and migration, aggregation to reasoning using logic (DL and FOL) constructs. Advances in automatic reasoning and the availability of semantic processing tools encourage analysts to extend existing link analysis methods towards contextual data processing. To demonstrate presented method, a proof of concept environment IAFEC Ontology Toolkit has been described. It delivers initial financial fraud identification schemes (rules) based on set of problem solving ontologies. The novelty in such approach comes from incorporating heterogeneous types of data, which usually are processed by graph methods. The semantic tool, extend capabilities of graph-based (homogeneous) approach by delivering context-aware indirect association identification, and inference path explanation and inspection capabilities. Presented material describes the method and analytical algorithms, which demonstrate description logic reasoning and graph-based semantic association identification and ranking. Developed method has been implemented, as a Protégé OWL 5.0 environment extension, supplemented with web-services delivering distributed data processing, aggregation (not available in ontology languages). The environment provides declarative processing capabilities enabling analysts to design configurable processing flow, and new financial fraud identification schemes.

BackgroundMigration is a stressful process of resettlement and acculturation that can often negatively impact the mental health of migrants. International migration to Japan, a country with dominant ethnic homogeneity, is growing steadily amid an ageing domestic population and severe labour shortages.ObjectivesTo identify the contemporary barriers to, and facilitators of, mental well-being among the migrant population in Japan.DesignSystematic reviewData sourcesPubMed, ProQuest, Web of Science, Ichushi and J-StageEligibility criteriaResearch articles examining the mental well-being of international migrants in Japan that were published in English or Japanese between January 2000 and September 2018 were included.Data extraction and synthesisFull texts of relevant articles were screened and references of the included studies were hand-searched for further admissible articles. Study characteristics, mental well-being facilitators and barriers, as well as policy recommendations were synthesised into categorical observations and were then thematically analysed.ResultsFifty-five studies (23 published in English), surveying a total of 8649 migrants, were identified. The most commonly studied migrant nationalities were Brazilian (36%), followed by Chinese (27%) and Filipino (8%). Thematic analysis of barriers to mental well-being among migrants chiefly identified ‘language difficulties’, ‘being female’ and ‘lack of social support’, whereas the primary facilitators were ‘social networks’ followed by ‘cultural identity’. Policy recommendations for authorities generally described more migrant support services and cross-cultural awareness among the Japanese public.ConclusionAccess to social support networks of various types appears to be an influential factor affecting the mental well-being of international migrants in Japan. More research is necessary on how to promote such connections to foster a more inclusive and multicultural Japanese society amid rapid demographic change.PROSPERO registration numberCRD42018108421.

Introduction: Type 2 diabetes mellitus (T2DM) has been associated with higher rates and poorer prognosis of infections, mainly due to poor glycemic control, reduced response of T-cells and neutrophils, and impaired migration, phagocytosis, and chemotaxis of leukocytes. However, the impact of T2DM on acute cholangitis (AC) has not been assessed so far. Thus, we aimed to explore this association by means of a systematic review of the literature. Methods: This systematic review was carried out based on the recommendations stated in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched the PubMed/MEDLINE, Web of Science and SCOPUS databases to identify relevant publications depicting an association between T2DM and AC from the inception of these search services up to present. Results: We detected a total of 435 eligible records. After we applied the inclusion and exclusion criteria, a total of 14 articles were included in the present systematic review. Included manuscripts focused on the potential role of T2DM as a risk factor for the development of AC and on its contribution to a worse prognosis in AC, e.g., development of sepsis or other complications, the risk of AC recurrence and the impact on mortality. Conclusions: As compared to non-diabetic individuals, patients with T2DM have a higher risk of AC as a complication of choledocholithiasis or gallstone pancreatitis. Several oral hypoglycemic drugs used in the management of T2DM may also be involved in the onset of AC. Diabetic patients who suffer from AC have a higher likelihood of longer hospital stays and sepsis, as well as a higher risk of mortality and more severe forms of AC as compared to non-diabetic individuals.

Large-scale application migration to fog computing is now being seen in the IT industry. The IoT is a prototype for connecting everyday objects to the web, such as sensors, gadgets (including those used in healthcare), and smart cameras. By analysing the data produced by the device, the IoT proposes a paradigm that simplifies infrastructure management and disaster recovery, hence improving the quality of life for humans.Fog Computing is a new computing paradigm that has emerged in recent years to meet the needs of latency-sensitive, geographically dispersed applications with high computational requirements. Fog computing is popular because it may be deployed near to the IoT nodes. Fog computing expands the computational, storage, and network capabilities of the cloud and serves as an intermediary layer between IoT devices and sensors. The nature of fog nodes makes resource management more difficult in fog. With fog computing, services and resources may be made available outside the cloud, close to the end devices. The inclusion of several heterogeneous devices, some of which may be mobile, makes ensuring adequate quality of service (QoS) in a fog system very difficult. Several quality-of-service considerations are accounted for, and QoS-aware techniques are provided in various portions of the fog system. So, in this article, we take a look at what's been done so far to ensure quality of service in fog computing. FogQSYM (Fog Queuing System) is an analytical model for Fog applications that helps to partition the application into many tiers and efficiently distribute resources based on factors such as memory, network speed, and processing power. When the infrastructure is built with lightweight computing devices, effectively allocating resources in the fog environment becomes a challenge. In a unified fog computing setting, we discuss how to assign tasks and locate virtual machines.
