Lying, Feeding and Activity Preference of Weaned Piglets for LED-Illuminated vs. Dark Pen Compartments

Little is known on the effect of light on pig behaviour. The choice behaviour of weaned piglets kept under two different light-emitting diode (LED) illuminance levels was investigated: 32 piglets (in two batches) were housed in a preference test room composed of two identical double pen units. One side of the pen unit was permanently illuminated with 600 lux, while the other was darkened to almost 0 lux (~0 lx); by using a passageway, piglets could move between the two sides. The “lying”, “eating” and “activity” behaviours were evaluated during three days in the first, third and fifth experimental week based on video recordings and a 5-min time sampling method. At first, piglets preferred to stay in the 600 lux illuminated compartments. Then, this preference decreased for the “eating” and “activity” behaviours and reversed for the “lying” behaviour, with the darkened compartments being preferred. The results also show that pen soiling was higher under 600 lux, but feed consumption was not affected by the illuminance. Since pigs choose between the two illuminance levels to perform specific behaviours, illuminance could be used to divide the pens into functional areas and, thus, help in meeting pigs’ behavioural needs.

Historical Vltava River Valley–Various Historical Sources within Web Mapping Environment

The article deals with a comprehensive information system of the historic Vltava River valley. This system contains a number of resources, which are described. For old maps, which are the basis of the whole system, their georeferencing and potential problems in creating seamless mosaics are described. Other sources of data include old photographs, which are localized and stored in the system, along with the definition point of the place from which they were probably taken. The vectorization of data is described, not only for area features used for the analysis of land-use changes, but also for the vectorization of contours. These were vectorized from old maps and are substantial for the creation of historic DEM. Vectorized footprints of buildings and vectors of other functional areas subsequently serve as a basis for the procedural modeling of the virtual 3D landscape. The creation of such a complex and broad information system cannot be described in one article. The aim of this text is to draw attention to a possible approach to the presentation and visualization of the historic landscape, along with links to important documents.

The purpose of the article is to study the impact of the ICT sector on economic development of countries based on the comparative analysis of this sector development in some Eastern European countries. Within the article, economic development of the outlined countries in 2010-2019 was studied and analyzed. The analysis of the impact of the ICT sector on the GDP formation allowed to single out certain groups of countries under this indicator and to identify the characteristics that are inherent to them. Using the correlation-regression analysis made it possible to analyze the ICT impact on economies development of Hungary, Bulgaria, Poland, Romania, Slovakia and the Czech Republic. Authors paid a special attention to the study of the influence of various factors on the ICT sector development. Accordingly, an analytical study of the dependence of the ICT sector weight in the GDP of the countries on the following parameters: enterprises that employ ICT specialists; enterprises that provided training to develop/upgrade ICT skills of their personnel; percentage of the ICT personnel in total employment; using Internet for Internet banking, % of individuals; enterprises who have ERP software package to share information between different functional areas; enterprises selling online (at least 1% of turnover), % of enterprises; online purchase in the last 12 months, % of individuals; enterprises having received orders via computer mediated networks, % of enterprises. Within the article, the features of the ICT sector development in the COVID-19 context are examined, and it is analyzed how the pandemic has affected the development of this sector in long and short terms. The study showed that the ICT sector today already plays a key role in the development of the national economies. Countries where the sector is developing faster show better performance and economic development.

Monitoring and Ecological Risks of Heavy Metals of Urban Soils in Different Functional Areas Based on Plasma Technology

Heavy metal pollution in soil has become a global environmental problem in recent years. This study assessed heavy metals' pollution distribution, level and ecological risk in soils from different functional areas in Shihezi City, China. Heavy metals (Cr, Cu, Pb, Zn, Ni, and Cd) were measured using atmospheric pressure discharge plasma and inductively coupled plasma mass spectrometer. The mean concentration of all heavy metals in soil was higher than heavy metals' background values. The spatial distribution of Cr is the most different, and the distribution of Cu and Zn are similar in other functional regions. The single pollution index indicated that the heavy metals in industrial, traffic, and residential areas were enriched, and the pollution of Cd was more severe than others. The Nemerow pollution index showed that the near Manas River basin coast is alert (still clean), the industrial area is moderately polluted, and all other functional areas are lightly polluted. The potential ecological risk index demonstrated that only the nearshore Manas River Basin is at a mild ecological risk level, while all other functional areas are at a moderate ecological risk level. The determinate power of DEM, temperature, and precipitation were all over 65%, which meant that the topographic and climatic factors were the main factors affecting the change of heavy metal content. Secondly, socio-economic factors are important factors to promote the change of heavy metal content in soil.

Technologies for studying functional neural networks of the human brain based on data of nuclear functional magnetic tomography

Nuclear functional magnetic resonance imaging (fMRI) is one of the most popular methods for studying the functional activity of the human brain. In particular, this method is used in medicine to obtain information about the state of the functional networks of the patient’s brain. However, the process of processing and analysis of experimental fMRI data is complex and requires the selection of the correct technique, depending on the specific task. Practice has shown that different processing methods can give slightly different results for the same set of fMRI data. There are a number of alternative specialized software packages for processing and analysis, but the methodology still needs improvement and development. We are working in this direction: we analyze the effectiveness of existing methods; we develop our own methods; we create software services for processing and analysis of fMRI data on the basis of the distributed modular platform “Digital Laboratory”, with the involvement of the supercomputer NRC “Kurchatov Institute”. For research we use experimental fMRI data obtained on the scanner Siemens Verio Magnetom 3T at the Kurchatov Institute. One of our tasks within the framework of this project is to improve the technology for studying large-scale functional areas of the cerebral cortex at rest. To build a hierarchical model of interaction of large-scale neural networks, a verified binding of functional areas to anatomy is required. Today, there are a number of generally accepted atlases of the functional areas of the human cerebral cortex, which, nevertheless, are constantly being finalized and refined. This article presents the results of our study of the Glasser atlas for the consistency of voxels within one region and the connectivity metrics of voxel dynamics.

International Human Resource Management

Nowadays, internationalization is key for the survival of firms. Internationalization of a firm involves an internationalization of all the functional areas of the firm, of which international human resource management (IHRM) is one of the most relevant. In an international context, managers should make decisions about what human resource practices are best suited to the firm's international operations. Being aware of the differences between domestic and international human resource management will help readers and managers to establish operational mechanisms to deal with country differences in terms of industrial labor, culture, and firm practices. Therefore, after reading this chapter, readers should be able to deal with aspects like adaptation or standardization of HR practices, international staffing, and relevant issues around expatriation and repatriation.

Trauma in Rural Areas

This chapter provides background on rural culture and the influence it has on the implementation of trauma-informed care. The cultural characteristics create additional obstacles to schools that are working to mitigate the adverse experiences that have debilitated many students. The poverty and drug use that families face has created a generation of children who struggle with chronic stress from the adverse childhood experiences that occur in their lives. This impedes all academic and many functional areas. Without appropriate education, teachers are often unable to reach students and misunderstand why students with multiple adverse experiences display behaviors. The authors share strategies to mitigate the impact of the adversities.

CrossQuestion Game: A Design of a Group-Based Assessment Tool to Enhance Student Motivation during Pandemic

This paper explores the effect of applying gamification and flipped classroom approaches through our group-based assessment game, the CrossQuestion, in the course of IT in Business. The course teaches basic IT fundamentals and their application in different functional areas of business and management. In Spring 2020-21, we delivered this course through Moodle platform, integrated with the Zoom video communication tool, to introduce the CrossQuestion game as supplemental resources to engage students. We conducted measurements using the Instructional Materials Motivation Survey scales to verify the game's learning effect. We divided students into an experimental group (85 students who played the CrossQuestion game through gamified flipped classroom session–Spring 2020-21) and a control group (60 students who previously underwent lecture-based instructions and individualized formal assessments–Spring 2019-20). The analysis of students’ grades confirms improvement by applying gamified flipped classroom group-based assessments in the learning process. The students’ questionnaire also confirms that group-based assessments can improve students’ motivation. We developed a game system that was attractive to the students, implying that it can be an effective instructional and recreational material to boost morale, increase collaboration, enhance engagement and socialization opportunities, especially during this challenging pandemic.
