Location referencing relative to landmarks or between two points of interest is often presented by navigation systems (e.g., GPS, Google Maps) in quantitative terms (e.g., 100m, 2km, etc.). However, humans refer to distances between points of interests in linguistic forms, such as very close, far, almost there, nearby, etc. When location information is presented to humans in quantitative terms, they often reprocess the quantities into linguistic terms and articulate it in linguistic labels because quantitative articulations are not directly in line with the natural human cognition. Therefore, this research seeks to evaluate the possibility of applying perceptive computing to reprocess quantitative location references from landmarks or two points of interest into linguistic labels easily understood by humans. A comparative analysis between the perception of quantitative distances and similar physical distances in an environment familiar to the subjects has been carried out, and there is a clear disparity between the perceptions in these two contexts.

Введение. Описаны современные электронные ресурсы как инструменты для топонимических исследований. До недавних пор использование геоинформационных систем (ГИС) в исследованиях географических названий нельзя было назвать масштабным. С развитием современных информационных технологий топонимические исследования приобрели новый характер, отличающийся новейшими подходами к сбору и обработке геоданных. Цель статьи – выявить, проанализировать и описать современные электронные средства для сбора и изучения топонимов с целью дальнейшего использования подобных ресурсов в разного рода исследованиях. Материал и методы. Наборы топонимов стали центральным компонентом систем GPS-навигации и онлайн-карт, которые сегодня широко используются в научных исследованиях. Массовая информатизация, развитие высокоскоростного интернета, доступность приобретения и использования портативных компьютеров и мобильных устройств, повышение компьютерной грамотности населения охватывают большинство стран мира, что отражается на качественно новых подходах к изучению топонимической лексики. Результаты и обсуждение. Революция цифрового картографирования и мобильных приложений позволяет простым гражданам вносить свой вклад в обработку топонимического материала в режиме онлайн. С появлением электронных систем Google Maps, Apple Maps, Яндекс.Карты, Bing Maps и им подобных топонимические исследования приобрели новый характер. Изыскания на уровне микротопонимии стали четче и подробнее. Наглядно показано, как можно использовать онлайн-топонимические словари, электронные карты, наукометрические базы данных, географическую базу данных GeoNames и Google-переводчик для проведения топонимических исследований. Указываются преимущества и недостатки современных сайтов и программ, ориентированных на исследования в области топонимики. Делаются выводы о целесообразности привлечения технических средств к топонимическим исследованиям в целом. Научные онлайн-дискуссии на таких площадках, как ResearchGate и Facebook, приводят к реальному взаимодействию ученых и помогают сделать научную мысль глубже, четче и ярче. Заключение. Принимая во внимание всевозможные погрешности вследствие применения современных описанных технологий, считаем необходимым контроль в виде сверки данных, например по этимологии географических имен и т. п. Упомянутые инструменты позиционируются как чрезвычайно полезные для выявления, описания, изучения, комплексного анализа и систематизации топонимического материала. Introduction. The article is devoted to the description of modern electronic resources as tools for toponymic research. Until recently, the use of GIS in geographical name research could not be called widespread. With the development of modern information technologies, toponymic research has acquired new features, characterized by new approaches to the collection and processing of geodata. The purpose of the article is to identify, analyze and describe modern electronic means for collecting and studying toponyms in order to further use such resources in various kinds of research. Material and methods. Toponymic sets have become a central component of GPS navigation systems and online maps, which are now widely used in scientific research. Mass informatization, the development of high-speed Internet, the accessibility of the acquisition and use of laptop computers and mobile devices, and improved computer literacy of the population cover most countries of the world, which is reflected in qualitatively new approaches to studying toponymic vocabulary. Results and discussion. The revolution of digital mapping and mobile applications allows ordinary citizens to contribute to the processing of toponymic material online. With the advent of electronic systems Google Maps, Apple Maps, Yandex.Maps, Bing Maps and the like, toponymic studies have acquired a new character. Any inquiry at the level of microtoponymy has become clearer and more detailed. The author explains the progress in the development of GIS systems, demonstrates how one can use tools such as online toponymic dictionaries, electronic maps, scientometric databases, the GeoNames geographic database and Google translator for conducting toponymic research. The advantages and disadvantages of modern sites and programs focused on research in the field of toponymy are indicated. Conclusions are drawn on the feasibility of attracting technical means to toponymic research in general. The author shows that online scientific discussions on platforms such as ResearchGate and Facebook lead to real interaction between scientists and help to make scientific thought deeper, clearer and brighter. Conclusion. Taking into account all kinds of errors due to the application of the modern technologies described, the author considers it necessary in some places to control in the form of reconciliation of data, for example, on the etymology of geographical names, etc. In general, the tools mentioned in the article are positioned as extremely useful for identifying, describing, studying, comprehensive analysis and systematization of toponymic material.

Atrial fibrillation (AF) is linked to an increased risk of adverse cardiovascular events. While rhythm control with antiarrhythmic drugs (AADs) is a common strategy for managing patients with AF, catheter ablation may be a more efficacious and safer alternative to AADs for sinus rhythm control. Conventional catheter ablation has been associated with challenges during the arrhythmia mapping and ablation stages; however, the introduction of two remote catheter navigation systems (a robotic and a magnetic navigation system) may potentially overcome these challenges. Initial clinical experience with the robotic navigation system suggests that it offers similar procedural times, efficacy and safety to conventional manual ablation. Furthermore, it has been associated with reduced fluoroscopy exposure to the patient and the operator as well as a shorter fluoroscopy time compared with conventional catheter ablation. In the future, the remote navigation systems may become routinely used for complex catheter ablation procedures.

Use of pedicle screws is widespread in spinal surgery for degenerative, traumatic, and oncological diseases. The conventional technique is based on the recognition of anatomic landmarks, preparation and palpation of cortices of the pedicle under control of an intraoperative C-arm (iC-arm) fluoroscopy. With these conventional methods, the median pedicle screw accuracy ranges from 86.7% to 93.8%, even if perforation rates range from 21.1% to 39.8%.The development of novel intraoperative navigational techniques, commonly referred to as image-guided surgery (IGS), provide simultaneous and multiplanar views of spinal anatomy. IGS technology can increase the accuracy of spinal instrumentation procedures and improve patient safety. These systems, such as fluoroscopy-based image guidance ("virtual fluoroscopy") and computed tomography (CT)-based computer-guidance systems, have sensibly minimized risk of pedicle screw misplacement, with overall perforation rates ranging from between 14.3% and 9.3%, respectively."Virtual fluoroscopy" allows simultaneous two-dimensional (2D) guidance in multiple planes, but does not provide any axial images; quality of images is directly dependent on the resolution of the acquired fluoroscopic projections. Furthermore, computer-assisted surgical navigation systems decrease the reliance on intraoperative imaging, thus reducing the use of intraprocedure ionizing radiation. The major limitation of this technique is related to the variation of the position of the patient from the preoperative CT scan, usually obtained before surgery in a supine position, and the operative position (prone). The next technological evolution is the use of an intraoperative CT (iCT) scan, which would allow us to solve the position-dependent changes, granting a higher accuracy in the navigation system.
