This paper aims to investigate the communicative role of reduced loudness in conference presentations based on auditory perception from a conversation analytic perspective. The subject of the study are five linguistic expert lectures recorded at international conferences in Germany within the framework of the GeWiss project. The focus of the investigation is on those passages that are pronounced much more quietly in contrast to the immediate (left and right) context. The auditory analysis is followed by the acoustic measurements performed with Praat, which exemplifies the intensity course with the graphs. The analysis is done within the framework of interactional linguistics. This means that the empirical data are interpreted in a specific (speech)situational context. From the analysis, it appears that the reduced loudness fulfills an important communicative function in the design of the scientific lectures, which is to signal the less relevance in the (con)textual information hierarchy. It was observed that the speakers pronounce certain contents (comments on the speech situation, additions added as supplement or extension to what is said, remarks on the research background, and meta-commentaries) more quietly to mark them prosodically as secondary and thus to weaken their effect. In this context, the reduced loudness proves to be an anti-emphasis, allowing the speakers to divert the listeners’ attention from the less important or non-pertinent information in the scientific presentations.

The authors present possible applications of thermal data as an additional source of information on an object’s behaviour during the technical assessment of the condition of a concrete surface. For the study one of the most recent propositions introduced by Zoller + Fröhlich company was used, which is an integration of a thermal camera with a terrestrial laser scanner. This solution enables an acquisition of geometric and spectral data on the surveyed object and also provides information on the surface’s temperature in the selected points. A section of the dam’s downstream concrete wall was selected as the subject of the study for which a number of scans were carried out and a number of thermal images were taken at different times of the day. The obtained thermal data was confronted with the acquired spectral information for the specified points. This made it possible to carry out broader analysis of the surface and an inspection of the revealed fissure. The thermal analysis of said fissure indicated that the temperature changes within it are slower, which may affect the way the concrete works and may require further elaboration by the appropriate experts. Through the integration of a thermal camera with a terrestrial laser scanner one can not only analyse changes of temperature in the discretely selected points but on the whole surface as well. Moreover, it is also possible to accurately determine the range and the area of the change affecting the surface. The authors note the limitations of the presented solution like, inter alia, the resolution of the thermal camera.

The problem of evaluating and defining physical endurance of athletes has been the subject of a great body of research and scientific discussion. In team sports, especially football, the energy protection of working muscles in players requires the use of almost all metabolic pathways: aerobic, anaerobic and aerobic-anaerobic. Because of the varying pace of action, the share of energy conversions in muscle cells changes rapidly during a match. Another concern voiced by scientists and football coaches is the question of whether fitness training should always be performed with football balls. The aim of this paper was to present the necessity of monitoring the development of aerobic fitness in football players, and also to answer the question of whether motoric training in football may be performed with balls.

Airborne laser scanning (ALS) is one of the LIDAR technologies (Light Detection and Ranging). It provides information about the terrain in form of a point cloud. During measurement is acquired: spatial data (object’s coordinates X, Y, Z) and collateral data such as intensity of reflected signal. The obtained point cloud is typically applied for generating a digital terrain model (DTM) and a digital surface model (DSM). For DTM and DSM generation it is necessary to apply filtration or classification algorithms. They allow to divide a point cloud into object groups (e.g.: terrain points, vegetation, etc.). In this study classification is conducted with one extra parameter–intensity. The obtained point groups were used for digital spatial model generation. Classification is a time and work consuming process, therefore there is a need to reduce the time of ALS point cloud processing. Optimization algorithm enables to decrease the number of points in a dataset. In this study the main goal was to test the impact of optimization on the results of a classification. Studies were conducted in two variants. Variant 1 includes classification of the original point cloud where points are divided in the groups: roofs, asphalt road, tree/bushes, grass. On variant 2 before classification, an optimization algorithm was performed in the original point cloud. Obtained from these two variants object groups were used to generate a spatial model, which was then statistically analyzed.

The integrated absorption coefficient of rovibrational bands is calculated for three different cases, namely for separated rotational and vibrational motions, for the non-rigid model which takes into account the coupling between above mentioned motions using the Kratzer-Fues potential and the soft body model, for which only rovibrational states exist. It is shown that the shape of P and R bands for higher rotational quantum numbers depends on the applied model of rotational - vibrational transitions.

The article presents an analysis of new intensifiers mega- and giga- and words prefixed by them in contemporary colloquial Polish. The author tried to describe the morphologic behaviour of these prefixes, their semantic value and syntax. Focus was put mainly on determining the semantic value of those new intensifiers and their current usage in Polish. It appears that although current dictionaries of Polish language do not even mention the colloquial usage of mega- and giga-, those prefixes are commonly used in spoken and written language, not only by teenagers, but also by adults, including journalists and advertising copywriters.

Purpose. The aim of the study was to assess lactate and glucose concentrations as indicators of anaerobic capacity in a highlyranked female junior swimmer. Methods. Ten trials of a 5 × 200 m backstroke step test were performed between December 2008 and July 2011. Each trial was video-recorded and blood samples were drawn from the ear lobe 1 min after completion of each step to measure lactate and glucose concentrations. Results. During maximal effort, lactate concentrations of 5.1 to 13.1 mmol · l-1 were recorded, while glucose concentration varied from 6.6 to 8.1 mmol · l-1. Correlations between lactate and glucose concentrations were significant in most tests. The shape of lactate and glucose curves revealed an improvement in the swimmer’s endurance ability during subsequent tests. Conclusions. Analysis of fluctuations in lactate and glucose concentrations appears to be a relevant indicator of the anaerobic capacity of experienced swimmers.

A tennis player has a very limited time to hit an incoming ball; however, the ball delivery time is affected by playing on different surfaces. Consequently, the playing surface can affect also other match characteristics as players can reach more incoming balls or can move on the court with different intensity (cover more distance). Aim of Study: The aim is to analyze the rally pace characteristics and the frequency of rally shots in men's matches in the Australian Open, French Open and Wimbledon in 2017. Material and Methods: We analyzed 24 male matches in the Australian Open, French Open and Wimbledon in 2017. Analysis of variance including post-hoc tests and Cohen d were used to compare the point duration, number of rally shots, time between the points, rally pace and work to rest ratio among these tournaments. Results: The rally pace (mean ball flight time between the opponents) was the fastest in the Australian Open (1.22 s) and was significantly faster (p=0.003) compared to the French Open (1.35 s). The rally pace in the Wimbledon reached 1.27 s and Cohen d showed large effect between the rally pace in the Wimbledon and French Open or moderate effect between the Australian Open and Wimbledon. There were other differences among the tournaments, but the lowest number of rally shots (4.07), point duration (5.30 s) and time between points (18.82 s) was reached in the Wimbledon. More than 50 % of all points were finished within the first four shots (most in the Wimbledon - 66%). Conclusion: These findings show and endorse the impact of surface differences on the game performance in professional tennis and can be used to shape specific training sessions on different surfaces.

Terrestrial laser scanning (TLS) is one of the instruments for remote detection of damage of structures (cavities, cracks) which is successfully used to assess technical conditions of building objects. Most of the point clouds analysis from TLS relies only on spatial information (3D–XYZ). This study presents an approach based on using the intensity value as an additional element of information in diagnosing technical conditions of architectural structures. The research has been carried out in laboratory and field conditions. Its results show that the coefficient of laser beam reflectance in TLS can be used as a supplementary source of information to improve detection of defects in constructional objects.

Physical Education classes fail to reach the minimum levels of moderate-vigorous activity recommended by international policies (50% of the class duration). Although several methodological strategies have been suggested in scientific literature to combat this limitation, few proposals exist in educational practice in this context. In this sense, the objective of this work was to integrate the emerging high intensity interval training method into a traditional learning unit of Physical Education with the intention of increasing intensity. The results showed that the students analysed improve their body composition and some components of the physical condition, in a non-significant manner. In conclusion, it seems to be a priority to include methodological strategies during physical education classes in order to achieve adequate intensity. The method presented in this practical proposal shows a positive trend in improving health in schoolchildren, although future research is necessary to confirm or refute the results found.

Purpose. The aim of the study is to characterize physical activity and physical inactivity of the inhabitants of the Liberec region in their common life. Basic procedures. The research sample consisted of 818 males and 831 females aged 15-69, which were either systematically or randomly drawn from throughout the region. Physical activity and its correlates were assessed using the IPAQ questionnaire. Main findings. According to self-reported data, 10% of the inhabitants are insufficiently physically active, 30% are sufficiently physically active, and 60% are highly physically active. The median of performed physical activity in the inhabitants in Liberec region expressed in MET · min-1 · week-1 was 3822 MET · min-1 · week-1 (IQR = 4371). On average, men spent sitting 393 min and women 415 min in total during a working day. Out of the total sample of respondents, 58% of the inhabitants in the Liberec region were of normal weight, 9% were underweight, 23% were overweight and 10% obese. Conclusions. These facts point to the necessity of increasing knowledge about the negative impacts of inactive behavior and emphasizing the advantages of performing regular physical activity along with the need to establish such conditions that would contribute to physical activity performance.

The article aims to show changes in the level and intensity of intra-industry trade between the Central European Free Trade Association (CEFTA) and the European Union. The analysis covers the period from CEFTA’s inception to the time when most of its member countries joined the EU. The structure of trade was examined using the Gruber-Lloyd indices of intra-industry trade (IIT), which are frequently used in such analyses. The IIT indices were calculated for 5,712 products according to 6-digit CN classification divided into 31 sections. The analysis showed that in 1993-2003: - The Gruber-Lloyd intra-industry trade indices for CEFTA’s trade with EU countries increased considerably. The greatest increase was noted for Poland (85%), Romania (61%), the Czech Republic (54%) and Slovakia (43%), while the slowest growth in the IIT index was reported for Bulgaria (20%). - The analyzed period marked a clear diversification in the growth of IIT indices by CN section in reference to individual countries. Countries with the lowest IIT indices (Bulgaria, Romania and Slovakia) modified the structures of their trade with EU countries to a greater extent than countries with relatively high indices. - Another important change is that most countries displayed a tendency toward concentration of trade with the highest IIT indices in an increasingly smaller number of CN sections. Notably, there was also a “shift” in the concentration of the highest IIT indices toward sections 15-20, meaning those characterized by a relatively high level of innovation and technological advancement.

Regular moderate-intensity exercise provides health benefits. The aim of this study was to examine whether the selected exercise intensity and physiological responses during exergaming in a single and multiplayer mode in the same physical space were game-dependent. Ten males (mean ±SD, age: 23 ±5 years, body mass: 84.2 ±15.6 kg, body height: 180 ±7 cm, body mass index: 26.0 ±4.0 kg·m−2) played the games Kinect football, boxing and track & field (3 × ~10 min, ~ 2 min rest periods) in similar time sequence in two sessions. Physiological responses were measured with the portable Cosmed K4b2 pulmonary gas exchange system. Single play demands were used to match with a competitive opponent in a multiplay mode. A within-subjects crossover design was used with one-way ANOVA and a post-hoc t-test for analysis (p<0.05). Minute ventilation, oxygen uptake and the heart rate were at least 18% higher during a multiplayer mode for Kinect football and boxing but not for track & field. Energy expenditure was 21% higher during multiplay football. Single play track & field had higher metabolic equivalent than single play football (5.7 ±1.6, range: 3.2-8.6 vs 4.1 ±1.0, range: 3.0-6.1, p<0.05). Exergaming in a multiplayer mode can provide higher physiological demands but the effects are game-dependent. It seems that exergaming with low intensity in a multiplayer mode may provide a greater physical challenge for participants than in a single play mode but may not consistently provide sufficient intensity to acquire health benefits when played regularly as part of a programme to promote and maintain health in young adults.

The starting point of this project is the fact that we are constantly “under the influence of someone else”. From an early age, our perception of reality is shaped by the environment (community) in which we live, i.e. by our parents, friends, teachers, but also by the so-called mass media. Opinion-forming is undoubtedly deliberately instrumentalised through the implementation of a strategy aimed at obtaining the approval of its receiver. The objective of this study is to discuss different types of linguistic manipulation. We will also propose an analysis of different types oflinguistic manipulation, in particular syntactic.

On children, HIIT program is being used by coaches as a way of rapid improvement. The values of the intervals vary from the target of the period. The study’s purpose was to find out if HIIT in different interval protocols improves children’s swimming performance. In the study participated 18 rookie swimmers (9 boys and 9 girls), aged 11.6 ±1.5. The HIIT protocol in both groups included the set of 2 * 4 * 17.5 m (freestyle and freestyle kick, respectively). The first group (HIIT 1) had a 10 sec interval while the second (HIIT 2) - a 1 min between the HIIT reps. Swimmers performed in 35 m freestyle (35F) and 2 min free kick (2’ FK) trials at maximum effort. The performance (T), the number of strokes (SN) and the stroke length (SL) were measured at 35F, the covered distance at 2' FK and the heart rate (HR), the rated perception of exertion (RPE) at 35F and 2’ FK. Regarding the results, all parameters improved significantly (p = 0.01). The use of a 4-week swimming program with training 4 times per week, in which two were HIIT, improved children’s performance and efficiency in swimming. Intervals of 10 sec or 1 min did not alter the improvement.

The paper aims to clarify the misunderstandings concerning the semantic description of derivative verbs created through exchange of prefixes. The description of a class of verbs which up to now have been regarded as expressing the intensity of an action (e.g. przekarmić ‘to overfeed’, przesolić ‘to oversalt’) had to undergo deep changes, including the elimination of lexemes which were created using two morphemes simultaneously (napracować się ‘to have worked a lot’ ← pracować ‘to work’). A detailed analysis has enabled us to prove that where others saw intensity, there was in fact effectiveness. Derivatives included in this category express three grades of effectiveness: high (as in ubawić się ‘to have rather enjoyed oneself’, wybiegać się ‘to have run enough’), excessive (as in przesolić ‘to oversalt’, zapić się ‘to loose life due to alcohol addiction’) and maximal (wytruć ‘to poison everyone’, domyć ‘to wash something clean’). Moreover, other lexemes need to be included in this class, namely those which are incorrectly seen as determining methodicalness (objeść ‘to eat all of someone’s food’), as well as exhaustivity (wybić ‘to kill everyone’, wyniszczyć ‘to thoroughly destroy’). Such a description will promote effectiveness, while eliminating small semantic sub-groups that are not uniform in their structure.

The article presents an analysis of words prefixed with maxi- in contemporary French. We tried to describe the morphologic behaviour of this prefix and its semantic value, where it works as a feature intensifier. Focus was put on the productivity and vitality of the prefix. The maxi- prefix appeared in French in the 70s. It entered the language through fashion clothing. Then its use spread widely, mainly thanks to advertising. Currently it appears in several fields other than fashion, including description of cosmetics, household appliances, transportation and tourism. It can be found in the naming of companies, products, website addresses, etc. It is also used by many French in everyday language, e.g. in internet blogs. Dictionaries give only a few examples of its use, mainly in the language of fashion, which does not cover all possible potential combinations of maxi-, mainly with nouns and adjectives.
