Developing competency profiles of IT specialists based on semantic analysis of vacancies

The article focuses on applying Big Data processing methods and tools for creating specialists' competency profiles. It covers the approach developed to formulate the key competencies required for the IT vacancies. The first stage of the research includes carrying out a semantic analysis of the IT vacancies database. The second stage includes clustering of the results of semantic analysis and using them for building the map of the competencies of IT specialists. The modularity score reveals a significant isolation of the specialties in this area. The performed approach can be implemented in designing the professional standards and competency based education programs. © Published under licence by IOP Publishing Ltd

Corrosion Of The Gas Pipelines Of The Field Medvezhiye In The Different Landscape Types

A forecast of the corrosion activity within different landscapes of the cryolithozone is poorly studied previously. This study represent a close correlation between the proportion of corroded sections of the gas pipeline route of the gas field Medvezhye (the North of Western Siberia, Russia) and the deviation of the redox potential of soils (ΔEh) depending on the specific landscape types (tract groups). Our study revealed that the maximum value of the standard deviation of the redox potential (ΔEh) predetermines the maximum currents of the differential pairs aeration of soils that activate electrochemical corrosion processes in pipelines. The value of ΔEh is proposed to use as the main indicator of the activity of corrosion of the landscape types in the permafrost region

Cloud information system «Redactor.Online» for the create of periodic scientific-educational editions

The article presents the approaches to the creation of cloud information system for automation of business processes related to the preparation and publication of periodic scientific and educational publications (publishing). The aim of the research is the development of concepts, models, patterns, architecture of such a system, the choice of software implementation. The urgency of development based on the results of a study of existing and used in practice technologies for creating electronic versions of scientific journals and other types of scientific and educational resources. It is expected that the use of cloud-based systems will reduce the time and cost of publishing houses, as well as improve the quality of published material (for example, through the use of their interactive and multimedia elements, add comments and assessment opportunities articles and so forth.).Description is given on an example of cloud Redactor.Online system developed by small innovative enterprises of Petrozavodsk State University «Internet-business-system». As a means of implementation chosen freelydistributed products, such as PostgreSQL, PHP, Yii Framework.Logically, the cloud structure of the system is a set of components, based on common data sources and interacting with each other. The main components of the system are the basic (general) part of promo-site system, editorial offices of periodicals created in the system, media sites, mobile applications editions, complex control system as a whole.The central element of the system architecture is the editorial offices. It provides a set of features related to the preparation for release and publication of the magazine, including the management of the lifecycle of the article (step preparation of the article the author, its review, proofreading, typesetting, translation, publication, and export to external citation indexes). Available functionality of this component is determined by the role assigned to the user - the editorial staff or author. Allocate such basic roles (offices), as a author office, reviewer office, corrector office, translator office, designer office, the editor’s office. A single user can have multiple roles, and perform various functions related to the preparation of articles for publication (eg, translate, and adjust the paper). You can also specify the settings in the publication, and the role of the steps which are required and which are not needed.Using Redactor.Online system built on the basis described in this paper approaches will significantly reduce the time and costs for the implementation of business processes related to organizational activities of publication and for potential users of the system, including educational and research institutions, engaged in release electronic journals. system interfaces and subsystems allow the Internet fast enough to create the appropriate publication site and configure its design, content, access parameters, modes of operation, in accordance with the requirements of the creator
