Abstract

Since 1978 the retreat of Ecology Glacier in the vicinity of Henryk Arctowski Station has opened new ice-free areas for colonization by terrestrial organisms initiated by pioneer microbes. Samples were collected from the soil surface, at 0, 5 and 20 cm below surface close to glacier front, then stored at below -20°C . Total bacterial count (TC), estimated by epifluorescence microscopy, reached high values, of 1010 g-1 dry wt. Healthy looking bacterial cells of mean volume 0.0209 µm3 at 0 cm to 0.0292 µm3 at 20 cm made up from 7% at 0 cm , to 30% at 20 cm of total bacterial population. The number of colony forming units (CFU) accounted for only 0.02% of TC. Taxonomically they belonged to the a, b, g subdivisions of the proteobacteria and to the Cytophaga-Flavobacterium-Bacteroides (CFB) group. Morphophysiologically CFU bacteria were diverse, from Gram variable short coccal forms to very long rods or filaments. Randomly selected CFU colonies were characterized by low sugar assimilation and high esterase/lipase activity. Spore forming bacteria – absent from 0 and 5 cm , formed a small fraction of 175 cells g-1 dry wt at the 20 cm depth. Filamentous fungi were relatively abundant and represented mainly by oligotrophs.

Abstract

The author believes that one all-inclusive assessment of Marx’s philosophy is inevitably misleading. Although Marx constructed one theory that has a texture of a uniform fabric, the fabric has been woven with threads of two very different qualities. His presentation of capitalist instability, exploitation and alienation has the quality of scientific explanations. But his treatment of dialectic, economy formulated in terms of priceless commodities and his vision of communism is fantastic and arbitrary.

Abstract

Economic development is strictly dependent on access to inexpensive and reliable energy sources based on diversified primary fuels. The strategic framework for the construction of the energy mix is defined in the Energy Policy of the State, the content of which, in terms of its mandatory elements, has been specified in the Energy Law. The task of the Energy Policy of the State is to create the shape of the future power sector, including designing the most advantageous regulatory, system and technical solutions guaranteeing the appropriate level of energy security of the country, monitoring of the system’s evolution and also designing and implementing changes aimed at the optimization of the functioning mechanisms. The vision of the development of the power system at the global level should also reflect changes in the formation of dispersed civil energy structures. Unfortunately, the results of the conducted analyses reveal existing imperfections of the data acquisition and information system, which should be used in the planning process. This issue is particularly important from the perspective of the dynamically developing concept of the energy self-sufficiency of communes and the emergence of energy clusters. The present paper describes the functioning of strategic planning in the field of the electric power system with an illustration of the improperly functioning mechanisms of information transfer in the context of the advancement of dispersed civil energy structures.

Abstract

The article analyzes the names given today to the children of inhabitants of Przemyśl — followers of Catholicism and Orthodoxy, at the same time showing their differences and similarities within both religions. In the same urban, communication and cultural community, Catholic and Orthodox live side by side (often for many generations). Despite everything, they to some extent retain their own identity (culture, traditions and customs), which also manifests itself in the names given to children. For a more complete picture of the situation, the names of the two older generations (parents and grandparents) were also presented.

Abstract

This introduction to the volume outlines the conception of the pedagogical city. The author stresses flows, or continuous exchange between citizens as specific to city life. Such flows concern also thinking, which contributes to the creation of a community that one may identify, afer Aristotle, as koinopolis – an educational community of shared thinking, ‘a great teacher’. Against the background of the condition of the global city, the conception of pedagogical city contributes to the theory of social pedagogy, and to the conception of pedagogy of place in particular (including urban community education). One may speak, in this context, of koinpolitanism – a trait of thinking capable of inspiring the flow of changes taking place in the cities of today. The papers collected in this volume contribute to the development of this idea.

Abstract

In the paper I show why we should consider Stoicism as the historical source of St. Thomas’s distinction between ‘conscience’ and ‘synderesis’. I claim that the Stoic terms syntērēsis and syneidēsis became, through the ages, the Thomistic synderesis and conscientia. The Stoic syntērēsis meant ‘self-preservation’, and in all animals this ‘first instinct’ refers to the body. The man is the only creature, which, because of its ‘rational nature’, preserves not necessarily its body but rather its soul, i.e. a system of values. Such preservation of someone’s axiological integrity equals ‘salvation’, and thus assimilates Stoicism to Christianity. In the Stoic system, human values follow ‘the nature’ (or ‘the human nature’ in particular), and in Thomism, they follow ‘synderesis’, or the natural inclination toward the good. In both cases we find a natural instinct that transforms itself into a rational structure of conscience. I also argue that, thanks to the moral phenomena of ‘adaptation’ (oikeiōsis) and ‘advancement’ (teleiōsis), the Stoic ethics is not completely egocentric, but incorporates also social duties.

Abstract

Internet of Things (IoT) will play an important role in modern communication systems. Thousands of devices will talk to each other at the same time. Clearly, smart and efficient hardware will play a vital role in the development of IoT. In this context, the importance of antennas increases due to them being essential parts of communication networks. For IoT applications, a small size with good matching and over a wide frequency range is preferred to ensure reduced size of communication devices. In this paper, we propose a structure and discuss design optimization of a wideband antenna for IoT applications. The antenna consists of a stepped-impedance feed line, a rectangular radiator and a ground plane. The objective is to minimize the antenna footprint by simultaneously adjusting all geometry parameters and to maintain the electrical characteristic of antenna at an acceptable level. The obtained design exhibits dimensions of only 3.7 mm × 11.8 mm and a footprint of 44 mm2, an omnidirectional radiation pattern, and an excellent pattern stability. The proposed antenna can be easily handled within compact communication devices. The simulation results are validated through measurements of the fabricated antenna prototype.

Abstract

In the age of digital media, delivering broadcast content to customers at an acceptable level of quality is one of the most challenging tasks. The most important factor is the efficient use of available resources, including bandwidth. An appropriate way of managing the digital multiplex is essential for both the economic and technical issues. In this paper we describe transmission quality measurements in the DAB+ broadcast system. We provide a methodology for analysing parameters and factors related with the efficiency and reliability of a digital radio link. We describe a laboratory stand that can be used for transmission quality assessment on a regional and national level.

Abstract

Visible Light Communication (VLC) is a technique for high-speed, low-cost wireless data transmission based on LED luminaries. Wireless LAN environments are a major application of VLC. In these environments, VLC is used in place of traditional systems such as Wi-Fi. Because of the physical characteristics of visible light, VLC is considered to be superior to traditional radio-based communication in terms of security. However, as in all wireless systems, the security of VLC with respect to eavesdropping, signal jamming and modification must be analyzed. This paper focuses on the aspect of jamming in VLC networks. In environments where multiple VLC transmitters are used, there is the possibility that one or more transmitters will be hostile (or “rogue”). This leads to communication disruption, and in some cases, the hijacking of the legitimate data stream. In this paper we present the theoretical system model that is used in simulations to evaluate various rogue transmission scenarios in a typical indoor environment. The typical approach used so far in jamming analysis assumes that all disruptive transmissions may be modeled as Gaussian noise, but this assumption may be too simplistic. We analyze and compare two models of VLC jamming: the simplified Gaussian and the exact model, where the full characteristics of the interfering signal are taken into account. Our aim is to determine which methodology is adequate for studying signal jamming in VLC systems.

Abstract

The self-consistent optical-electrical-thermal-gain model of the oxide-confined edge-emitting diode laser has been used to simulate the room-temperature operation of the long-wavelength 1.3-µm quantum-dot (InGa)As/GaAs diode laser. The validityof the model has been verified using some experimental results for comparison. An impact of quantum-dot densityon laser operation characteristics as well as on temperature dependence of lasing threshold have been discussed.

Abstract

Due to globalized business operations, companies in different economic sectors are part of complex supply chain networks. Their value-added processes comprise product and information flows, e.g. with a focus on manufacturing, service or trade. Until the final product is delivered to the end customer, it needs to pass many different processes in cooperating organizations. As a result, there a lot of business-to-business (B2B) interactions with crossenterprise transactions, often including cross-border communications and sometimes even cross-industry trades with technological and often cultural implications. Especially the interfaces of supply chain networks are prone to inefficiencies, misunderstandings and delays due to a lack of standardized B2B transactions, which leads to waste in form of rework, errors and mistakes. In addition, new customers are hard to find for the manufacturing or trading company, since potential customers are so far limited to a regional network. The advantages of extending the customer base still need to be explored by many organizations. This paper discusses the opportunities by streamlining the communication along supply chain networks in a general fashion and then describes the application in a B2B automotive retail business. A concept of a web-based trading platform, which provides a seamless service for all steps of a convenient and efficient used vehicle remarketing business, is developed. It includes all phases, like offering and price finding in a comprehensive online platform, which also covers further activities, such as logistic services, financial transactions, and a mandatory feedback loop. The suggested B2B vehicle-trading platform enables a quick turnover of each transaction, which is analyzed and optimized based on the application of cross-enterprise Value Stream Management.

Abstract

The paper discusses political philosophy of Bogusław Wolniewicz. The leading idea of his general philosophy was rationalism of a specific type that he called ‘tychistic’ (meaning ‘based on fate’), or ‘transcendental’ (meaning ‘transgressing the limits of nature by reliance on human reason’). This self-description presents Wolniewicz as an author respecting his Christian background, though personally he did not espouse the complete body of precepts postulated by the Church. As a nonconfessional catholic he spoke in favor of Christian civilization which he identified with Western culture. This led him to the reject of liberalism, libertarianism and leftist ideologies. He wanted to be perceived as a democrat who supported civil and republican democracy based on the virtue of patriotism. He emphasized the essentiality of the possession of its own political state by each independent nation, and the most important circle of loyalty was for him a national community. Thus he undertook to defend a conception of cautious xenophobia that was expurgated of hate but dedicated to the defense of a national territory.

Abstract

The concept of conscience is analyzed here in two different ways: the systematic and the historical-literary. As to the first, systematic perspective, I distinguish (in part 1) three levels of conscience and on every level I identify two opposite categories (conscience that is ‛individual’ versus ‛collective’; ‛emotional’ versus ‛intellectual’; ‛motivating ex ante’ versus ‛evaluating ex post’). In the second, historical-literary perspective, I analyze two literary cases of fictional characters usually thought of as being guided or affected by conscience. The first case is the ancient Greek tragedy and here I offer (in part 2) a comment on the Sophoclean Antigone and the Euripidean Orestes presenting them both as dramas that contain an exemplary formulation of the phenomenon of conscience. Although Antigone and Orestes express their main principles of action in apparently different words, I suggest (in part 3) the two poetical visions of conscience are equally based upon a highly emotional behavior called pathos by the Greek. Thereby I provide a reason, why ancient philosophers created a new concept of conscience intended as an alternative to the poetical vision of human behavior. The new philosophical concept of conscience was based upon an axiological behavior called ethos. I also coin (in part 4) a concept of the ‛community of conscience’ where I distinguish four ‛aspects of solidarity’ in conscience, namely, somebody’s own self, a group of significant persons, a group of the same moral principles, and a sameness of life. In the end I turn (in part 5) to a historical-literary case in Joseph Conrad’s last novel The Rover (1923), which provoked a lively discussion among Polish authors and seems useful as an illustration of several levels of ‛solidarity of conscience’.

Abstract

The article presents personal memories of Professor Aleksander Koj’s alumni. Professor Aleksander Koj was a world-class biochemist of significant scientific achievements, a renowned authority in the field of acute-phase response regulation and acute-phase proteins. He was an excellent academic, a true Master, admired and followed by many Polish biochemists. Thrice he served as the Rector of the Jagiellonian University in Kraków. He navigated the University through a difficult time of political transformation in Poland, modernized the management system of the University and led to the commencement of the construction of the new University campus. He was the co-creator and the first Chairman of the Conference of Rectors of Academic Schools in Poland. He will be remembered as a devoted community worker aiming at strengthening the bond between the Polish community abroad and our homeland, propagating knowledge, promoting the concept of European integration, democracy and tolerance, as well as the collaboration between scientists, artists and men and women of culture. He was wise, righteous, and noble. Many had the honor of calling him their friend, and a great many saw in him a moral authority.

Abstract

In education, information and Communications Technologies mostly play the role of a medium of communication, as well as a means of imparting knowledge. ICT, however, is used less as a subject for student activity, i.e. a subject for students to learn, where they can operate the technology, as in robotics or mechantronics. Information technologies are also very rarely implemented in education as a way for students to build their identity and shape their attitudes towards their outside and inside worlds. In spite of this, in the history of educational technology there have been a number of researchers and educators who have promoted interesting ideas for implementing technologies as tools for human cognitive, affective, psychomotor and moral empowerment. Today such people are also present in education, however, they play unimportant roles on the periphery of formal education. This paper is a reminder of a number of ideas by theorists and researchers concerning the implementation of ICT, but mainly highlights the empowerment it gives students and its humanizing/humanitarian role.
