The analysis is based on a sample of 1015 citizens from Czechia. The cognitive energy literacy index (CELI), based on the knowledge of the energy mix in electricity production and the knowledge of the import/export of electricity in Czechia, is constructed in this article. The research aims to answer the following questions: What is the level of CELI within the population of Czechia? To what extent do the selected socio-demographic indicators affect the CELI? To what extent does CELI influence respondents' perceptions? The medium level of CELI is widespread across the population, while high and low levels of CELI are roughly equally shared. People with a high CELI are more likely to be older men with a university education. CELI also significantly affects the perception of behaviour on an individual, collective, and systemic level. Higher CELI is also associated with higher support for innovative solutions and renewable energy resources.

Analiza oparta jest na próbie 1015 obywateli z Czech. W artykule skonstruowano indeks kognitywnych umiejętności energetycznych (CELI), oparty na wiedzy o miksie energetycznym w produkcji energii elektrycznej oraz wiedzy o imporcie/eksporcie energii elektrycznej w Czechach. Badania mają na celu udzielenie odpowiedzi na następujące pytania: Jaki jest poziom CELI w populacji Czech? W jakim stopniu wybrane wskaźniki społeczno-demograficzne wpływają na CELI? W jakim stopniu CELI wpływa na postrzeganie przez respondentów? Średni poziom CELI jest rozpowszechniony w całej populacji, natomiast wysokie i niskie poziomy CELI są mniej więcej równo podzielone. Osoby o wysokim CELI to częściej starsi mężczyźni z wyższym wykształceniem. CELI istotnie wpływa również na postrzeganie zachowań na poziomie indywidualnym, zbiorowym i systemowym. Wyższe CELI wiąże się również z wyższym poparciem dla innowacyjnych rozwiązań i odnawialnych źródeł energii.

This study investigates listeners’ perceptual responses in audio-visual interactions concerning binaural spatial audio. Audio stimuli are coupled with or without visual cues to the listeners. The subjective test participants are tasked to indicate the direction of the incoming sound while listening to the audio stimulus via loudspeakers or headphones with the head-related transfer function (HRTF) plugin. First, the methodology assumptions and the experimental setup are described to the participants. Then, the results are presented and analysed using statistical methods. The results indicate that the headphone trials showed much higher perceptual ambiguity for the listeners than when the sound is delivered via loudspeakers. The influence of the visual modality dominates the audio-visual evaluation when loudspeaker playback is employed. Moreover, when the visual stimulus is present, the headphone playback pattern of behavior is not always in response to the loudspeaker playback.

This study aims to investigate how grazing is perceived across the Curvature Subcarpathians (Romania) by farmers. We investigate farmers’ attitudes toward and understanding of grazing practice and associated processes involving small ruminants (sheep and goats). Additionally, we review the scientific literature and new discussions about grazing vs overgrazing terms and changes in the Romanian small ruminant livestock. Results of the survey on the total of 101 case studies from villages in 3 counties (Damboviţa, Buzau, and Vrancea) show that: (i) grazing is differently perceived; (ii) most of the areas designated for grazing are located near riverbanks (over 55%); most of the respondents reported that the areas intended for grazing are quite close to the inhabited areas; distances are less than 2.5 km; and over 60% of respondents believe that the areas are continuously subject to soil degradation processes; (iii) answers given in connection with the issues addressed provide both relevance to the Curvature Subcarpathians (6792 km2 ) and the potential impact of higher pressure of grazing on local areas due to the discouragement of specific transhumance policies (more than 60% required subsidies). The average stocking density is about 4.7 head per ha. In general, beyond different farmers’ perceptions, a scientific question remains open regarding the quantitative impact of grazing on hydrological processes. Hence, a field survey (e.g., rainfall-runoff experiments) to assess grazing pressure on water and soil resources will be performed.

Both JPED and JPEG200 compression method are based on human visual perception properties commonly there are used classical quality metrics. In the paper there is applied S-CIELAB filtering and metric to evaluate quality of compression in JPEG standards measured as frequency weighted signal to noise ratio.

PL

Chociaż kompresja JPEG, jak i JPEG2000 bazują na pewnych cechach ludzkiej percepcji, do oceny jakości obrazów najczęściej wykorzystywane są proste metryki. W artykule wykorzystano do oceny jakości kompresji sandardami JPEG ważony stosunek sygnału do szumu przy użyciu filtracji S-CIELAB.

The main goal of every method of automatic analysis, recognition and also understanding of any medical signal is to follow the physician’s method of observation and thinking. Apparently it is easy, because the procedures of human interpretation of biosignals are now well standardized. In fact the real way of making observations and thinking about diagnosis highly depends on the observer experience and personal skills. In this paper, a new eyetrack-based approach is proposed for quantitative assessment of these important factors. The visual experiment carried out on cardiologists of various professional experience supplied the scanpaths data for the analysis in context of observed ECG traces the proposed approach, without the verbalization necessity, allows the cardiologists know-how to be extracted, analyzed and implemented in the automatic interpretation algorithm for better emulate the human way of thinking. It can be very useful for designing of new algorithms for automatic ECG signal analysis, recognition and also understanding by the machines.

A virtual environment is an interactive graphic system mediated through computer technology that allows a certain level of reality or a sense of presence to access virtual information. To create reality in a virtual environment, ergonomics issues are explored in this paper, aiming to develop the design of presentation formats with related information, that is possible to attain and to maintain user-friendly application.
