Opis:

Game engines are platforms that make it easier to create computer games. They allow you to integrate and combine into single unit individual game elements such as animations, interaction with the user, or detection of collisions between objects. Game engine is a software that facilitates the production of games for platforms such as desktops, consoles, and mobile devices [1]. In addition to specialized editors, game engines provide ready-made functionalities that can be used by users. A great advantage of using the game engine is the possibility of their reuse. Game engines are an example of software isolating rigid logic and game rules, from easily modifiable and expandable components, which can be used repeatedly in a way that does not require great modifications. This article is an attempt to perform a comparative analysis of three engines to create games: CryEngine, Unreal Engine, and Unity. The criteria for comparison will be technical capabilities and factors influencing the popularity and acceptance of engines by users. The aim of this article is to show the strengths and weaknesses of engines and to present the differences between these tools.

Opis:

Cellular solids are materials made out of solid strut or thin plate like structures bridged together. They occur in nature in the form of honeycombs, wood, bone, cork etc. These materials possess a unique combination of properties such as low thermal conductivitv, low density and high energy-absorption. Foams are a class of cellular solids, generally made by dispersing gas into a liquid material and then cooling it to solidify. They are categorized as open-cell and closed-cell foams. Depending on the solid materials that are made into foams, they are also categorized as polymeric foams, metallic foams, and ceramic foams. Due to developments in material science and manufacturing lechniques, advanced foams have found potential for use in automobile, aircraft, and space vehicle structures. In the paper the comparative study of the hybrid foam microstructures is presented. Hybrid foam is a new, still developed material that is built of the aluminum open cell foam matrix filled with other material (here: elastomer). The numerical models based on cubic geometry in different configurations are developed. The FE analysis of the compression test is curried out. The results are presented and analyzed due to the microstructure geometry influence on the material behaviour.

Opis:

The paper presents two kinds of cooperating teams: traditional and virtual, and proposes a new measure of the team virtuality level. Some representative teamwork characteristics, such as team member competencies, team diversity, leadership, and team decision-making are analyzed and compared depending on the degree of virtuality. Moreover, the team climate as one of the team performance measures is also analyzed and compared in virtual and traditional teamwork conditions. The considerations show that the virtuality level is crucial for virtual and face-to-face team comparison, virtual and hybrid team analysis and answering the question how to improve online collaboration processes and performance.

Opis:

There is a relatively small but important research oeuvre in the biological study of comparative and international politics. This essay is situated within that literature. One significant issue in comparative politics is corruption—its causes, its consequences, and remediation. This study focuses on the first point with a focus on a biosocial variable that might be at work. Prior research has suggested that health status of a nation affects extent of democratization, electoral integrity, and fragility of states. In no case is health status the dominant predictor. Given its relationship with those three aspects of a polity, this paper examines the effect of health status on corruption across states. Given prior results, there is good reason to hypothesize that as health status increases, states are less apt to have high rates of corruption. The base for this analysis comprises data on over 150 nations. Among the variables as part of that data set are health status and corruption. Results are reported and discussion centers on the meaning of the data and what the implications might be.

Opis:

The article reports on empirical research into the differences in child-rearing practices between present-day families and families living at the turn of the 21st century. The concept of child-rearing practices is addressed from the point of view of social theories of learning and socio-cognitive theories which constituted the basis for the research discussed. Results show that a portion of practices significantly differs in each group, and a portion remains unchanged. The biggest difference concerns ‘deferment of gratification’ as a factor for the development of many social skills. In the present-day family group this child-rearing effect has largely disappeared.

An ad hoc questionnaire was designed, validated and administered to 113 Slovenian and 100 Spanish teachers. The data were collected and analysed with the use of descriptive and inferential statistics. Among the most relevant findings, it is noteworthy that Spanish teachers focus on providing feedback on receptive skills while their Slovenian colleagues pay more attention to productive skills. Also, results from both groups reveal a lack of FL pronunciation feedback and scarce attention to interactive aspects of communication.

Opis:

Instance selection is often performed as one of the preprocessing methods which, along with feature selection, allows a significant reduction in computational complexity and an increase in prediction accuracy. So far, only few authors have considered ensembles of instance selection methods, while the ensembles of final predictive models attract many researchers. To bridge that gap, in this paper we compare four ensembles adapted to instance selection: Bagging, Feature Bagging, AdaBoost and Additive Noise. The last one is introduced for the first time in this paper. The study is based on empirical comparison performed on 43 datasets and 9 base instance selection methods. The experiments are divided into three scenarios. In the first one, evaluated on a single dataset, we demonstrate the influence of the ensembles on the compression–accuracy relation, in the second scenario the goal is to achieve the highest prediction accuracy, and in the third one both accuracy and the level of dataset compression constitute a multi-objective criterion. The obtained results indicate that ensembles of instance selection improve the base instance selection algorithms except for unstable methods such as CNN and IB3, which is achieved at the expense of compression. In the comparison, Bagging and AdaBoost lead in most of the scenarios. In the experiments we evaluate three classifiers: 1NN, kNN and SVM. We also note a deterioration in prediction accuracy for robust classifiers (kNN and SVM) trained on data filtered by any instance selection methods (including the ensembles) when compared with the results obtained when the entire training set was used to train these classifiers.

Opis:

Study of religion describes, analyzes and compares how certain human beings do in fact express their faith in terms of particular scriptures, religious figures, sacred rituals, community solidarity, etc. — and how all these explicitly religious phenomena may relate to other aspects of people’s lives. It also aspires and addresses the questions to be even-handed, objective, based on evidence that may be checked by any competent inquirer, and non-committal on claims to divine revelation and authority. It is in principle comparative, not in a judgmental evaluative sense, but in terms of describing and analysing comparable elements or phenomena from various religious traditions, using the same criteria in each case. The paper begins with a brief report on the study of religion in the context of India and presents in detail Rabindranath Tagore’s (1861–1941) views on the need, an objective and philosophy behind the comparative study of religion. As Tagore observes, when studying religion one usually chooses among two alternative approaches: to do research on the secret text or to study the rituals. Tagore accepts fully none of them and instead suggests to rediscover how human aspiration for transcendence works in practice, how it sustains the individual — often marginalized by the power of institutionalised religion — and society, and how it generates new cultural forms. For Tagore, the essence of religion lies is the will to transcend the limit of the self-cantered being towards an ideal of perfection — which he calls divinity of Man. His understanding of the “religion of Man”, as he puts it, is discussed in the major part of the paper.

Technologia zabezpieczania układów elektronicznych za pomocą powłok konforemnych umożliwia zwiększenie stopnia automatyzacji produkcji podzespołów elektronicznych. Powłoki konforemne są cienkimi warstwami o grubości 25 - 50 mm zabezpieczającymi elementy układów przed działaniem takich czynników jak ścieranie, temperatura, ozon, pleśnie, wilgoć oraz promieniowanie ultrafioletowe. Własności fizyczne i skład chemiczny powłok gwarantują różny stopień zabezpieczenia przed wspomnianymi czynnikami środowiskowymi. Cechą charakterystyczną tego rodzaju zabezpieczeń jest możliwość dokładnego odwzorowania powierzchni. W artykule przedstawiono zarówno niektóre praktyczne informacje dotyczące powłok konforemnych, jak i wyniki badań własnych dotyczące ich wpływu na niektóre parametry układów.
The conformal coating technology of protecting the surface of electronic assemblies from harsh environment has been developing recently as a result of increasing automation of electronic production. The conformal coating is a thin protective layer of 25 - 50 urn thickness which can provide resistance to several stresses including abrasion, shock, temperature, ozone, mould, humidity and ultraviolet degradation etc. The physical and chemical compositions of various coatings offer different degrees of protection. The characteristic feature of this type of protection is a possibility of circuit surface conformal mapping. In this article some practical information, as well as the results of own investigations of different type of conformal coatings are presented.

Andrzej Wróblewski
Zbylut Grzywacz

Opis:

The contents of the article is a comparison of two important in the post-war Polish art pictures: ‘The Queue Goes On’ of 1956 by Andrzej Wróblewski (1927-1957) and its travesty – ‘The Queue Still Goes On’ (for Andrzej Wróblewki) of 1973 by Zbylut Grzywacz (1939-2004). Both works had political meaning – read usually as existential metaphors of communist system. Wróblewski’s painting was read in the spirit of marxist revisionism of the ‘Thaw’ period, Grzywacz’s painting in the spirit of democratic rhetoric used by the opposition fighting for ‘human rights’ in the 1970s. The author compares both pictures, together with the expressions assumed as their titles, and exams the relations between them. Art history methods play an additional role as the actual aim of consideration is showing the deeper, spiritual ground of relations of both artists. It is a task for hermeneutics, which is described by the author as a gift of reading signs and following these signs as far as possible. ‘Each repeti- tion is equally primary as the work itself’ these words by Hans-Georg Gadamer are a compositional frame for the essay and an interpretation directive. How did Grzywacz ‘repeat’ Wróblewski’s painting? The author is looking for an answer on a few interpretation planes. Wróblewski’s art was rich in symbols of metamorphosis – it was permeated by the typical for European post-war art stream of cosmic vitalism and biological regeneration, appearing in visual metaphors of ‘a life chain’ among others. Examining reflections of this stream in Grzywacz’s art reveals its traces not in the area of moralistics and history, but in science. Both painters were agnostics, with Grzywacz being a naturalist – he was an active collector in the field of geology and entomology. Symbols of metamorphosis, which were unusually seldom in his painting, were connected with these sciences – the artist’s life passions – what is proved in his picture ‘Chrysalis’ painted during his terminal illness.

Przedstawiono i omówiono przyczyny nieporozumień, które powstały w pojmowaniu audytu i kontroli. Zwrócono także uwagę na różnice, głównie prawne, dotyczące audytu i kontroli. W artykule skupiono się przede wszystkim na audycie wewnętrznym i kontroli wewnętrznej. Audyt zewnętrzny i kontrolę zewnętrzną przeanalizowano w węższym zakresie z uwagi na fakt, iż w tym zakresie, praktycznie, nie występują zasadnicze różnice.
The article discusses the essential issue of substantive audit and control comparison, in terms of objectives, tasks, location in the organization and related legal aspects. Detailed definitions of both concepts have been analyzed in both national and international practice. The reasons for the misunderstandings arising from the understanding of audit and control are presented and discussed. Attention has also been paid to differences, mainly legal, concerning audit and control. The article focuses mainly on internal audit and internal control. External audit and external audit were analyzed in a narrower scope, since there are practically no significant differences in this regard.

Opis:

This paper presents the control designs for an autonomous forklift vehicle that drive the vehicle from an initial configuration to a final one. Three stabilization controls, which are chained-form time-varying control, sigma-transformed discontinuous control, and navigation-variables-based discontinuous control, for a forklift vehicle are compared by simulations. The sigma-transformed and navigation-variables-based discontinuous controls provide fast convergence motions from an initial to a final configuration, while the time-varying-based control provides oscillatory motion and slow convergence. The sigma-transformed discontinuous control has a set of discontinuous points in which, from a practical point of view, the control signals can blow up if a vehicle enters the set. The navigation-variables-based control, which also has a discontinuous point at the final configuration, does not produce blown up control signals since its boundedness nature. Discussion on the implementation of control algorithm is elucidated for the three stabilization controls for the forklift vehicle.

Opis:

The development of moral competence is affected by both internal and external factors and has been researched by many scientists. The present study investigated a) whether the five factors of personality, gender and geographical area would affect ones’ moral competence, b) whether the personality factors Openness to Experience, Conscientiousness and Agreeableness would be correlated positively with moral competence in everyday life, whereas Extraversion and Neuroticism would be correlated negatively with morality, c) if there will be differences in students’ moral competence exhibited in everyday life and that expressed in PE/sports framework and d) whether type of school, factors of personality, as well as moral competence exhibited in sports-framework would all be significant factors for the interpretation of a student’s moral competence. The sample consisted of 331 junior high students (7th and 8th graders) (Mage = 12.47, SD = 0.740), who were given the Moral Competence Test Greek Version (Mouratidou et al. 2003), the Moral Judgment Test in Physical Education(Mouratidou et al. 2008), and the Inventory of Child Individual Differences (Besevegkis & Pavlopoulos 1998). The results indicated that of the five-factor personality model only Conscientiousness can affect moral reasoning ability in everyday life and that the type of school can account for less than 5% of variance when predicting moral competence in high school students.

Opis:

The paper presents findings of the comparative study on relationships between remembrance story-telling and the transitional reconstruction of political identities. It identifies in which areas and fields of impact governments tend to use interpretations of the past to promote new leadership visions of society. Moreover, it verifies theoretical hypotheses related to the politicised remembrance and its role as a political asset during transformations, as well as it considers the theoretical framework of democracy-building (and a common prediction of its universal character). As a result, the study offers a detailed picture of the way remembrance narratives are transformed into explanations, justifications or legitimisation of new, post-authoritarian identities based on qualitative-to-quantitative analysis of the intensity of story-telling and its links with transitional identity politics. In the conclusion, the Authors present their consideration of research findings, and they discuss it with reference to the nature of transitional government’s remembrance policy as a sphere of social influence.

Broadcasting services seek to optimize their use of bandwidth in order to maximize user’s quality of experience. They aim to transmit high-quality digital speech and music signals at the lowest bitrate. They intend to offer the best quality under available conditions. Due to bandwidth limitations, audio quality is in conflict with the number of transmitted radio programs. This paper analyzes whether the quality of real-time digital DAB+ broadcasted radio programs surpasses the quality offered by analog FM radio. We also perform a subjective and objective quality assessment comparative study of the HE-AAC v2 audio codec used in DAB+. The subjective studies were carried out using the MOS test methodology, whereas the objective tests were realized using the ViSQOLAudio metric. These studies were followed by a questionnaire concerning the migration from analog to digital radio domain.

Opis:

The purpose of investigation was comparison of engine's output while equipped with different types of turbocharging systems. Engine used during research was Toyota's SI engine with displacement of 1296 cm3. Intake and exhaust manifold were modified by introducing fixed and variable geometry turbocharger. The third system was electrically driven charger ensuring both constant and variable boost pressure. Regulatory parameters of fuel injection and ignition system weren't changed. On the basis of carried out research , it was affirmed that there is a possibility of introducing charging system into the engine without changes of mentioned regulatory parameters. Proper choice concerning charging systems allows improving torque characteristic in wide range of engine's rotational speed. Electrically driven charger giving maximum boost pressure provides significant improvement in low engine's speed range, whereas in higher range it is not showing so much advantage. In medium engine's speed range the best result is given by variable geometry turbocharging system. In this application boost pressure had to be reduced to 0.25105 [Pa] in order to provide stable engine's run in all conditions including variable engine's speed and whole range of throttle opening angle.

In the age of digital media, delivering high quality content to consumers is one of the most demanding tasks. There exist numerous broadcasting standards, with different pros and cons, and the DAB/DAB+ (Digital Audio Broadcasting) system is one of the most popular among them. From an engineer’s perspective, efficient resource management under limited bandwidth conditions has always been a challenge. In this paper a subjective quality assessment study of the DAB and DAB+ broadcasting system is performer on a representative group of signal samples. It describes the radio link, including a fully functional transmitter designed for the purpose of this test, as well as the receiver side representing a commercially available consumer device, for a truly real-time and end-to-end quality evaluation.

Opis:

Malware is a software designed to disrupt or even damage computer system or do other unwanted actions. Nowadays, malware is a common threat of the World Wide Web. Anti-malware protection and intrusion detection can be significantly supported by a comprehensive and extensive analysis of data on the Web. The aim of such analysis is a classification of the collected data into two sets, i.e., normal and malicious data. In this paper the authors investigate the use of three supervised learning methods for data mining to support the malware detection. The results of applications of Support Vector Machine, Naive Bayes and k-Nearest Neighbors techniques to classification of the data taken from devices located in many units, organizations and monitoring systems serviced by CERT Poland are described. The performance of all methods is compared and discussed. The results of performed experiments show that the supervised learning algorithms method can be successfully used to computer data analysis, and can support computer emergency response teams in threats detection.

The study deals with definition and cross-comparison of soil infiltration capacity at two selected sites located in cadastral territories of Nosislav and Žabčice, Czech Republic. In order to assess the soil infiltration capacity in the areas of interest Niva and Kovál over the course of the 2010 growing season, four trips were made with three measurements taking place during each trip. A method of doublering infiltration measurement was applied, based on the use of two concentric cylinders in field conditions and the subsequent data processing via geographical-empirical method according to Kostiakov. The soil infiltration capacity was assessed with regard to physical properties determined by an analysis of intact soil samples using Kopecky cylinders. The results indicate a reduced infiltration capacity due to soil compaction and also significant differences between the two sites, primarily caused by differences in soil type and, hence, different physical characteristics.

Opis:

Digital mammography is one of the most widely used approaches for breast cancer diagnosis. Many researchers have demonstrated the superiority of machine learning methods in breast cancer diagnosis using different mammography databases. Since these methods often have different pros and cons, which may confuse doctors and researchers, an elaborate comparison and examination among them is urgently needed for practical breast cancer diagnosis. In this study, we conducted a comprehensive comparative study of the state-of-the-art machine learning methods that are promising in breast cancer diagnosis. For this purpose we analyze the largest mammography diagnosis database: Digital Database for Screening Mammography (DDSM). We considered various approaches for feature extraction including principal component analysis (PCA), nonnegative matrix factorization (NMF), spatial-temporal discriminant analysis (STDA) and those for classification including linear discriminant analysis (LDA), random forests (RaF), k-nearest neighbors (kNN), as well as deep learning methods including convolutional neural networks (CNN) and stacked sparse autoencoder (SSAE). This paper can serve as a guideline and useful clues for doctors who are going to select machine learning methods for their breast cancer computer-aided diagnosis (CAD) systems as well for researchers interested in developing more reliable and efficient methods for breast cancer diagnosis.

The article is intended as a voice in the discussion on language aptitude, with particular regard to its two components: memory and language analytic ability. It will be argued here that – unlike memory, favoured by Skehan (2003) – it may be the language analytic ability manifested, among others, as considerable dexterity in retrieving constructional schematizations to decode language innovation, which grows in importance with learner proficiency. It will also be argued here that both capacities, the said ability as well as memory, should be considered in relation to working memory, which should be understood in terms of storage and processing considered separately and ascribed to individual differences, and not as a homogenuous storage-and-processing space.

Opis:

Flotation and adsorption characteristics of the most commonly used cationic and anionic collectors with high grade orthoclase were investigated through the electrokinetic potential measurement, microflotation, Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM) studies. According to the obtained results, orthoclase had high flotation recovery with amine and oleic acid based (OAB) collector at certain pH ranges no flotation response was observed with petroleum sulfonate at different pHs. In contrast to the flotation recovery differences, the electrokinetic potential measurements, FTIR and AFM analyses presented similar adsorption characteristics for all collectors. The results of electrokinetic potential tests showed that amine had a strong influence on the zeta potential of orthoclase. While amine turned the zeta potentials of orthoclase from negative to positive, sulfonate and OAB collector provided slightly more negative zeta potentials at certain pHs. In the case of FTIR and AFM analyses, each collector-treated orthoclase (CTO) sample displayed similar characteristic FTIR bands of CH2 group and micro topographical collector coated patches with different intensities. However, the interactions of each collector with orthoclase surfaces were altered by rinsing with acetone indicating that the interactions were mostly through the electrostatic forces and/or hydrogen bonding.

Opis:

In this work, the compressive residual strength tests results, Compression After Impact (CAI), are presented. The specimens were made of carbon-epoxy prepreg E722-02 UHS 130-14. Two variants of specimens were tested: samples undamaged and samples with damage that was centrally introduced by a drop-weight impact, as per the ASTM D7136/7136M standard. An impactor with potential energy equal to 15J and the type of support required by the standard were used. The size of impacted damages, defined as an area of damage on a plane perpendicular to the impact direction, and the equivalent diameter were specified using the flash thermography method. The tests were performed using the fixtures manufactured according to the ASTM D7137/7137M standard. The specimens were compressed to determine the residual strength. This value was afterwards used to specify the force levels for the fatigue tests. The fatigue tests were carried out under force control – with a sinusoidal shape, stress ratio R equal to 0.1 and frequency f 1Hz. Maximum force in a loading cycle Pmax was being increased after each thousand of cycles N until its value was close to the residual strength determined in the previously mentioned tests. In this work, the following relationships were presented: force-displacement P-δ for both static and fatigue tests and displacement-loading cycles δ-N for fatigue tests. A method of conducting the fatigue tests of CFRP composite was proposed, in which both the CAI specimens and CAI fixture were used. This allowed researchers to accelerate making initial comparisons between the two groups of specimens with damages – grouped relative to the way of conditioning.

BackgroundTurnover rates among nurses are much higher than in other professions. This poses a challenge for health managers in all countries. The purpose of this study was to investigate the factors affecting nurses’ turnover and the differences in this area between Iran and Poland.Material and MethodsIn this descriptive cross-sectional study, the population consisted of nurses working in state-owned hospitals in Poland (N = 165) and in Iran (N = 200). Data were collected using the Turnover Intention Scale, the Job Satisfaction Scale, the Work–Family Conflict Scale and the Workplace Support Scale. Use was made of the AMOS 24 and SPSS 22 software for data analysis.ResultsThe results showed that the predicted factors of nurses’ turnover intention in Poland and Iran were different. Workplace support and job satisfaction can reduce turnover intention among Polish nurses while the work–family conflict influences nurses’ turnover intention in Iran.ConclusionsProviding a flexible work plan in Iranian hospitals and enhancing teamwork and improving the spirit of cooperation in Polish hospitals could reduce nurses’ turnover intention in these 2 countries.

Opis:

In building speech recognition based applications, robustness to different noisy background condition is an important challenge. In this paper bimodal approach is proposed to improve the robustness of Hindi speech recognition system. Also an importance of different types of visual features is studied for audio visual automatic speech recognition (AVASR) system under diverse noisy audio conditions. Four sets of visual feature based on Two-Dimensional Discrete Cosine Transform feature (2D-DCT), Principal Component Analysis (PCA), Two-Dimensional Discrete Wavelet Transform followed by DCT (2D-DWT-DCT) and Two-Dimensional Discrete Wavelet Transform followed by PCA (2D-DWT-PCA) are reported. The audio features are extracted using Mel Frequency Cepstral coefficients (MFCC) followed by static and dynamic feature. Overall, 48 features, i.e. 39 audio features and 9 visual features are used for measuring the performance of the AVASR system. Also, the performance of the AVASR using noisy speech signal generated by using NOISEX database is evaluated for different Signal to Noise ratio (SNR: 30 dB to -10 dB) using Aligarh Muslim University Audio Visual (AMUAV) Hindi corpus. AMUAV corpus is Hindi continuous speech high quality audio visual databases of Hindi sentences spoken by different subjects.

Opis:

This paper investigates the current research in the field of the end-of-life vehicles (ELV) recycling network. The optimisation of the location of a network facilities in forward logistics in the automotive industry has received a lot of attention for many years but the reverse logistics for ELVs has been a subject of investigations since the beginning of 21st century. ELV recycling network design gained in popularity after the European Union and other countries like Japan, South Korea and recently China introduced legal obligations to organize a collecting or recycling network for used vehicles. When regulations are introduced, there is a need for a systemic solution to the problem, especially since the obligation to create a collection network is often accompanied by requirements related to its accessibility for vehicle owners or efficiency of operation. With the growing scope of legal regulations, companies or organisations responsible for the network are forced to redesign the existing recycling infrastructure in a given area so that it meets specific requirements. Initially, the most important criterion was network availability. Currently, the same importance is attached to economic, environmental and social aspects in order to meet the sustainability criteria. In this paper, forty one peer-reviewed published studies focused on network design were classified. Its main purpose is to provide an extensive review of state-of-the-art research published in the period 2000-2019. The scope of the review is limited to network design problems including facility location and flow allocation problems. Only papers that present mathematical models are considered. Studies on the ELV network design are classified based on: type of supply chain, type of network, optimisation problem, type of facilities, modelling technique, single/multi objectivity, objective function, period of time, solution approach and scope of implementation. The final part of the paper includes discussion of the methodology of the reviewed studies and some recommendations for future research area.

Opis:

Two poets mourning the death of their poet friends are Sepehri and Spencer in different contexts of Iran and England. The two poets who are dead are Forough and Sidney who have been great poets and have been admired by the mourning poets. To remember their friends, they have written poems to enliven the memory of their dead friends. Sepehri considers Forough, a female Iranian poet, a friend and a great poet. The methodology of this article is based on comparative literature with the emphasis on American school of comparative literature which considers aesthetics and attention to critique and analysis. This school regards literature as a universal phenomenon and in relation to other branches of human knowledge and fine arts. This school does not accept any boundaries in the field of comparative literature and believes in the study of literature as a whole, and compares literature with other arts and human sciences. The followers of this school believe that comparative literature is a method that broadens the view of man in the study of literary works and is an approach to go beyond national boundaries and believe the study of literary phenomena is between two or more different literatures or the study of the relation between a literary phenomenon and various sciences

Opis:

Modern cities are focused on the implementation of the assumptions of sustainable transport development. They invest in modern solutions and intelligent technologies that improve the mobility of residents and reduce energy consumption and pollution emitted by means of transport. This article deals with issues of smart urban mobility and carsharing, in particular, as one of the examples of the implementation of sustainable transport policy. The objective of this article is a comparative analysis of the pace of development of the carsharing markets in Poland and Germany. The analysis is carried out using statistical and comparative analysis methods. In addition, for a complete presentation of the problem raised, a literature analysis is performed. The research area covers two countries, Poland and Germany, from which ten cities for each are selected for analysis. In addition, to achieve the assumed objective, we also present the basic assumptions of smart mobility and solutions used in cities, and then determine the increase in the number of cars driving in the carsharing system. In addition, the factors influencing the change in transport patterns of urban residents are analyzed, and the importance of modern communication technologies in the development of carsharing systems is emphasized. The results of the analysis can be used as a tool to support the decisions of city authorities in the field of transportation management and, in particular, the implementation of carsharing systems. They also present the dependencies of the spread of this solution in a given urban space. They indicate the largest problems that may affect the introduction of this solution as an element of the city’s transportation system.

Opis:

Amino-acid derived compounds, for example N-α-lauroylarginine ethyl ester (LAE), N-α-myristoylarginine ethyl ester (MAE) and a 1:1 mixture of N-α-myristoylarginine ethyl ester with monolaurin (MAE + MLN) are examined for their cytotoxicity towards L929-Mouse connective tissue to explore their use as microbicidal agent, in comparison to sodium dodecylsulfate (SDS) as an anionic control detergent. MTT (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide Cytotoxicity assay method was used to determine IC50 value. Cytotoxicity of MAE is found to be more toxic as compared to LAE, having IC50 value 0.052 mg/ml against 0.68 mg/ml of LAE. But MAE when mixed with monolaurin (1:1), showed less toxicity with IC50 0.89 mg/ml. These results suggest that a combination of MAE and Monolaurin can be a potential candidate for studying its microbicidal properties.

Opis:

Credit scores are critical for financial sector investors and government officials, so it is important to develop reliable, transparent and appropriate tools for obtaining ratings. This study aims to predict company credit scores with machine learning and modern statistical methods, both in sectoral and aggregated data. Analyses are made on 1881 companies operating in three different sectors that applied for loans from Turkey’s largest public bank. The results of the experiment are compared in terms of classification accuracy, sensitivity, specificity, precision and Mathews correlation coefficient. When the credit ratings are estimated on a sectoral basis, it is observed that the classification rate considerably changes. Considering the analysis results, it is seen that logistic regression analysis, support vector machines, random forest and XGBoost have better performance than decision tree and k-nearest neighbour for all data sets.

Opis:

Pielęgniarki są ważnymi promotorkami zdrowia społeczności, więc muszą bardziej świadomie dbać o własne zdrowie, aby służyć jako rzeczniczki promocji zdrowia i wzory do naśladowania. Aktywność fizyczna jest jednym z istotnych wymiarów prozdrowotnych zachowań i zdrowego stylu życia. Celem niniejszego artykułu było porównanie aktywności fizycznej w czasie wolnym od pracy pielęgniarek i kobiet wykonujących inne zawody. Przebadano 100 pielęgniarek i 100 osób z grupy kontrolnej. Kontrolowano zmienne demograficzne, dobierając osoby badane „metodą doboru parami” pod względem dwóch zmiennych – miejsca zamieszkania oraz wieku respondentek. W badaniach posłużono się zbudowanym dla niniejszych celów badawczych kwestionariuszem ankiety. Badania ujawniły, że różnice dotyczą nie tyle form aktywności ruchowej, co jej częstości i jest to zazwyczaj związane z wiekiem badanych. Najczęstszymi formami aktywności fizycznej w obu grupach są spacery i jazda na rowerze, ale pielęgniarki podejmują je znacznie rzadziej, gdyż mają istotniej mniej czasu wolnego, zarówno w dni robocze, jak i wolne od pracy. Głównym motywem aktywności fizycznej dla pielęgniarek jest zdrowie (52%), zaś dla grupy kontrolnej przyjemność (35%). Pielęgniarki także istotnie częściej wykonują badania profilaktyczne oraz są przekonane o konieczności prowadzeniu zdrowego stylu życia.
Nurses are important promoters of health in society, so they must consciously take care of their health to serve as spokespersons for a healthy lifestyle and role models. Physical activity is one of the significant dimensions of health-related behaviors and a healthy lifestyle. The purpose of this article was to compare physical activity in the free time of nurses and women performing other professions. The research included 100 nurses and 100 women doing other professions. The respondents were tested with the matched pair-selection method, taking into consideration two variables: a place of residence and age. The survey questionnaire that was used was prepared for the purpose of a smaller study. The research revealed that the main difference relates not to the forms of physical activity, but its frequency and this is usually related to the age of the participants. The most common forms of physical activity in both groups are walking and cycling. However, nurses practice them with much less frequency. The essential reason for this is because they have significantly less free time, both on working days and holidays. The main motive of physical activity for nurses is health (52%) while in the control group – pleasure (35%). Nurses also significantly more often perform prophylactic and are convinced about the necessity of leading a healthy lifestyle.

Opis:

Japan has an unfavorable balance of trade in medical devices, and large Japanese companies hesitate to enter the medical device industry. This paper investigates the process of the expansion of the American medical device industry. It was concluded that the propensity for risk in the U.S.A. and Japan is different; both countries have different industries and ways of thought which construct their manufacturing cultures. A system called Investigational Device Exemption (IDE) indicates that US Medical Industries are in a stronger position than their Japanese counterparts. The American system allows purchasing of developing medical devices before pharmaceutical acquisition. Japan has no foster policy for medical venture, nor are medical devices tested strictly before pharmaceutical approval. It is predicted that the Japanese economy will no longer be able to grow in a stable manner just by relying on the large corporation-led export of manufactured goods, whereas those SMEs with the sophisticated technology, by accommodating the needs of the medical institutions, will be highly competitive internationally in a narrow and specialized market. The author points out that promotion for the medical device industry may help Japanese economic revitalization. Japanese companies and their government will have to support developing "diversity" of the players.
