In article the local market of services in the field of information technologies as a part of information space of the region including all institutional units and IT infrastructure of the region is considered. Such approach is caused by rather small contribution of this type of activity to a gross regional product in the conditions of economic crisis, reducing by the companies costs and freezing of large infrastructure projects. Development of information society is characterized by tendencies of promotion of mobile services, artificial intelligence, socialization, use of a cloud computing and is followed by involvement of households, state management and business in a common information space. However traditionally market research of IT services and information space represent the isolated researches of the market and humanitarian direction.The purpose of this article is development of a single technique and system of indicators for the analysis of the local market of IT services in information space of the region. Authors determinae components of information space in which there is a configuration of the local market, the demand and supply. Development of an analysis technique of the local market of IT services is preceded by the description of structure of information space of the region as the open system exchanging with the external environment information resources. Basic elements of structure are social and economic system in which the local market of IT services, ICT infrastructure and information resources functions. Information analysis base is the system of statistics which sources can be an official statistics, analytics of Internet resources and data of selective inspections of demand in the local market.The technique of a research represents an analysis algorithm of all components of information space and the market of IT services. For each analysis stage authors proved statistics for the solution of a certain task. At the final stage the temporary periods of the analysis, statistical dependences of result of market development of IT services on factors, conditions and restrictions are proved in the region. In the course of development of a technique the main problems of a research of the market of IT services, including connected, with lack of IT services as separate type of economic activity are revealed. Limitation of data for research of information region space is compensated by development of the universal questionnaire and results of field inspection in the course of accomplishment of a grant of the Russian Foundation for Basic Research. The need for implementation of educational programs in the field of IT technologies for the population is revealed that can serve as a demand growth incentive in the local market of IT services.The practical importance of technique consists in reasons for approaches to regulation of the local market of IT services in the conditions of the current state of information region space.

Cloud computing technologies have brought new attributes to the IT world. One of them is a flexibility of IT resources. It enables effectively both to downsize and upsize the capacity of IT resources in real time. Requirements for IT size change defines business strategy and actual market state. IT costs are not stable but dynamic in this case. Standard investment valuation methods (both static and dynamic) are not able to include the flexibility attribute to the evaluation of IT projects. This article describes the application of the Real Options Analysis method for the valuation of the cloud computing flexibility. The method compares costs of the on-premise and cloud computing solutions by combining put and call option valuation. Cloud computing providers can use the method as an advanced tool that explains hidden benefits of cloud computing. Unexperienced cloud computing customers can simulate the market behavior and better plan necessary IT investments.

During the initial peak of the COVID-19 crisis, for the approximately 6 weeks beginning on April 8, 2020 and continuing through mid-May 2020, our academic radiology department shifted all nonprocedural operations to a "Command Center" model. This intervention was designed to maximize faculty and resident safety while continuing to provide prompt radiology care to our patients and support to front-line clinicians. During this time most of our radiology faculty and residents worked remotely. The five on-site residents were stationed together in a single large reading room where they worked as generalists, supervised by remote faculty. This room became the hub of all clinical communications. This brief report describes this experience, reviewing what was done and what was learned. • Consolidating communications to a single room required careful planning and cooperation with the IT department. • VPN capacity was rapidly increased to allow essentially the full complement of faculty to be able to connect simultaneously if needed. • Clear lines of communication and innovative scheduling approaches at each divisional level were needed to optimize the division of labor [ABSTRACT FROM AUTHOR]

Presently, the weight of services sector is increasing in all economies and represents the main element of the gross domestic product in the developed countries. Consequently, in the last decennia, this sector captured the interest of researchers, both in academic and business media. Information Technology (IT) represents one of the most dynamic factors contributing to the technical progress in the design, process and supply of all categories of services. The theoretical and practical investigations already demonstrated the potential of the Information Systems adoption and implementation, to improve the organization performances (efficiency, productivity, organization competitiveness and development etc.). However, this potential is not always fully valued. The best performances could be achieved when the IT investments are aligned with internal capabilities and organizational processes within company strategy. The aim of this contribution is to review main published studies investigating the direct and indirect potential effects of IT on company performance in the service sector. There are also addressed issues regarding the measurement difficulties of the IT impacts on organization performance and the limitations generated by the service diversity and the fast dynamics of their market.

Designing efficient data center is more than ever a challenge for many companies when it comes to meet the requirements of having a greater and extensible computing capacity. It should be stored increasing volumes of data. Applications became increasingly complex. The requirements for running business operations should be very flexible. If we want that ICT infrastructure (Information Technology & Communication) to be able to offer, continuosly, high level of services, it is essential to rethink the "robustness" and the need for innovation in data centers. This is true for both servers and storage as well as for the processing power. Companies operating in this field help customers to optimize their data center availability and security by evaluating the energy consumption, cooling capacity and other factors involved in data centers upgrading. The objective is to obtain an optimum in terms of occupied space, most efficient power consumption and most effective cooling in order to achieve a sustainable long term data center operation. The development and modernization explosive data centers as a result to the three major trends existent in the IT (Information Technology) now: cloud computing, Internet of Things and Big Data [1, 9].

Purpose: In this paper, we assess the role of knowledge management (KM) practices as a key antecedent of KM performance. Also, we examine how information technology (IT) infrastructure is used as a driver of KM performance, organizational performance and innovation. In addition, the effects of IT infrastructure can be indirect. Specifically, we show that KM performance is a mediator between, on the one hand, IT infrastructure and, on the other hand, organizational performance and innovation. Design/methodology: Applying Partial Least Squares (PLS), a composite-based structural equation modeling, we have carried out a study among a sample of 82 Andalusian technology-intensive innovative companies adopting both a confirmatory and predictive purposes. Findings: First, both IT infrastructure and KM practices are key drivers of KM performance. Second, KM performance shows a significant direct impact on business performance and innovation outcomes. Third, the influence of IT infrastructure on business performance and innovation outcomes is not direct but indirect through KM performance. Finally, the model shows good fit values and appropriate predictive power to predict new observations of KM performance and organizational performance. Practical implications: This research provides insights for why some firms may not be realizing benefits from investing in IT infrastructure. KM performance is strongly needed for the successful implementation of IT infrastructure in the organizations. Originality/value: This study has a double research purpose, confirmatory and predictive. In this vein, it applies new PLS developments focused on the goodness of fit as well as on the predictive performance of the model. The findings are important for practitioners and researchers because this study makes a contribution to the literature on KM by supporting the perspective that the business and organizational performance are functions of the KM performance, a complementary resource through which the value of IT infrastructure is enhanced.

Enterprise resource planning (ERP) is an important innovation, affecting the business world by generating improvements both tangible and intangible in large companies and small and medium enterprises (SME). This study focuses on the determinants of success and the advantages of the adoption of this technology. To address these points, a comprehensive literature survey was carried out in order to formulate an original research model for ERP success evaluation and provide a prospect for IT infrastructure and integration. The model, thus suggested and taken within the Kingdom of Saudi Arabia (KSA) context, examines in a systematic approach the relation between the ERP acceptance determinants, the effects of the process of ERP systems diffusion, and the impacts expected on organizational performance. Obtained results underline two key determinants of ERP projects success: First, the preponderance of information control and the improvement in the use of competences. The second factor is the quality of team projects, the definition of team's mission, training, business processes reengineering, user acceptance, top management support and the selection of the ERP solution.

The advent of cloud computing has transformed the way companies managing their information technology (IT) and information systems (IS). Cloud computing provides three different service models, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). This study was aimed to analyse the effects of IT infrastructure transformation into IaaS model on the changes in IT management capabilities. Based on the literature review, a research framework was developed. The framework suggests four IT capabilities components that can contribute to organizational agility, namely IT supply management, IT-business partnership, IT proactive posture and Change readiness IT capability. The framework was used to guide a case study to collect empirical data in a telecommunication company in Indonesia. Analysing the results of the case study, changes in the organization's IT capabilities as the impact of IaaS adoption were discussed. This study provides insights into efforts to develop the required IT capabilities in order to realise the benefits from cloud computing adoption, in particular the IaaS. [ABSTRACT FROM AUTHOR]

The re-use of healthcare information for biomedical research is increasing and with it the importance of a consent management framework implementing computable consents. Based on requirements concerning a consent representation the Advanced Patient Privacy Consents (APPC) Profile of Integrating the Healthcare Enterprise (IHE) is evaluated and mapped to these requirements. As IHE APPC was developed for computable patient consents, the mapping of consents for research projects is possible by re-using the elements defined. Compared to other approaches like gICS, approaches using APPC can be based on commercial software products and integrated into IHE environments. IHE APPC was already successfully used in EHR projects like INFOPAT. For interoperability reasons IT platforms intending to support biomedical research including clinical data, research data, biomaterial and imaging data, IHE APPC seems to be an appropriate standard to choose.

Over the past three decades, business managers and academic researchers have shown considerable interest in understanding how information systems (IS) can lead to competitive advantages for firms. Although in the United States researchers have found that IS competences lead to competitive advantages, it remains unknown whether firms working in emerging economies can capitalize on IS competence for competitive advantages. This article examines the moderating effect of the learning intensity of organizations on the relationship between IS competence and competitive advantages in 122 Chinese firms. Data were collected from a mailed survey of 122 information-technology (IT) managers. The results indicate that flexibility of IT infrastructure, IT business skills, and learning intensity have significant effects on competitive advantages. The learning intensity of organizations positively moderates the relationship between IS business skills and competitive advantages, but has no moderating effect on the relationship between the flexibility of IT infrastructure and competitive advantages.

Significant exploitation and utilization of cloud computing in industry is come with and in the identical time vulnerable by unease regarding protection of data hold by cloud computing providers. One of the penalties of moving data processing and storage off business site is that organizations have fewer controls over their infrastructure. seeing that, cloud service (CS) providers must hope that the CS provider is capable to protect their data and infrastructure from both exterior and domestic attacks. Presently however, such hope can only rely on organizational procedures stated by the CS provider and cannot be remotely verified and validated by an external party. The central distinction between cloud computing and conventional enterprise internal Information Technology services is that the proprietor and the consumer of cloud Information Technology infrastructures are separated in cloud. This transform requires a safety responsibility severance in cloud computing. Cloud service providers (CSP) should safe the services they propose and cannot surpass the customers' authorities. Virtualization is a buildup utterance in the Information Technology world. With the assure to reduce the ever mounting infrastructure inside data centers connected to other important apprehensions such as ease of use and scalability, virtualization technology has been in advance recognition not only with IT experts yet also among administrators and executives as well. The progressively more growing rate of the approval of this technology has exposed these systems to new protection concerns which in recent history have been unnoticed or merely overlooked. This paper presents an in depth state of art gaze at present most old server virtualization explanations, as well as a writing study on different security matters found inside this virtualization technology. These problems can be practical to all the existing virtualization technologies accessible with no spotlight on a specific answer. Nevertheless, we do susceptibility investigation of two of the mainstream recognized virtualization answers: VMware ESX and Xen. to conclude, we illustrate some clarifications on how to progress the security of online banking and electronic commerce, using virtualization.
