The topic of this paper is the universal call to holiness with reference to the notion of „ordinary holiness”. The contemporary teaching of the Catholic Church, particularly since Vatican II, has underlined that holiness is both a gift and a task for all Christians. It is illustrated with several papal pronouncements by Paul VI, John Paul II and Benedict XVI. Finally the paper points out to some examples which confrm that any activity in life is appropriate for fulflling the call to holiness. It is also noticed that ordinary holiness is a positive reaction and response of Christ’s disciples to the signs of the time they face. Some of those signs of the time are nowadays: man’s changing attitude to the truth, to human life as a fundamental value, to conjugal love which is in its essence faithful and exclusive, as well as to service as a form of daily love.

Semiotics is the study of how signs are interpreted as references, and names are an obvious type of sign. Semiotics may therefore be considered a useful approach to all types of name study — whether personal names, place names, commercial names, or literary names. As described by C. S. Peirce, an act of reference consists of a sign (e.g., a word, word part, road sign, emblem, or simply a finger) and a referent (e.g., an object, conceptual model, or analytic definition). Furthermore, all acts of reference reflect one or more of three basic types of relationships: 1) similarity, 2) one-to-one correspondence, and/or 3) arbitrary convention. If a sign is interpreted as similar to a referent, it functions iconically. If it is interpreted as a designation or as caused by the referent, it functions indexically. If it is interpreted as referring to two or more indexical referents, it evokes related qualities and thereby functions symbolically. The primary interpretation of names is indexical. However, the purpose of this paper is to show how names, as signs, are also interpreted iconically and symbolically, even at the same time. Different types of names will be used to illustrate these semiotic functions.

The article consists of two parts. In the first one (introductory) I recall—following Edmund Husserl, Stanisław Ossowski and Adam Schaff—the main formulations of the “principle of transparency of the sign.” In these formulations it is usually said about (1) the transparency of the sign regarding objects denoted by the sign (denoted, designated and/or named), or (2) the transparency of the sign regarding its meaning (respectively, events, states of affairs and facts designated by the sign). However, as Husserl pointed out, one can also speak about (3) the transparency of the sign in relations to the activities and mental states of the sign’s users (senders and recipients). After all, only due to the transparency of the sign understood in this way, it is possible for people to communicate with each other, thus the sign can also has an expressive and communicative function. In turn, the second part of the article (essential) contains a reconstruction of the Leon Koj’s approach; Koj gave a consistently formalized form to the theory of sign based on the principle of transparency— the form of an axiomatized logical system (using Quine's formalism from his Mathematical Logic). One of Koj's main goals was also to indicate the close relationship between semantics and pragmatics, and even the primacy of pragmatics over semantics. Formal-logical tools have also shown that the theory of sign based on the principle of transparency neither contravene The Law of Non-Contradiction (at least in its psychological formulation), nor contain or imply semantic antinomies such us antinomy of the liar. Because it is a theory easily negotiable with Alfred Tarski’s theory of language levels.

This article presents examples of the relationship between culture, dance, and the body in the fields of communication (with oneself, the community, God/deity), the social hierarchy, social values, relations between the individual and the group, and relations between genders, from the perspective of the sociology of the dance. The sociological perspective also indicates the various historical, ritual, control, and regulatory roles that traditional and modern dances play in the communities in which they arise and are performed. The second part of the text contains a case study of the Japanese ankoku butoh dance. The author presents the philosophical roots of the dance (e.g., Japanese mythology, Zen Buddhist philosophy) and the creator’s personal experiences (childhood trauma and post-war social situation) as factors that influenced the dance’s development. The example of ankoku butoh illustrates the interrelation between cultural meanings and dance movements.

Polish Sign Language (PJM) is a natural communication system that has been evolving for two centuries. It is at the heart of the identity and culture of the Deaf community in Poland, but it is often marginalized and neglected. It first came under serious linguistic scrutiny not long ago, and more systematic research on it has been initiated in recent years by a team of researchers at the Section for Sign Linguistics at the University of Warsaw.

This account examines how episodes are constructed and measured, and how Peirce’s Index informs and even hastens the advancement of this process—from binding spatial features, to the awareness of participant roles and temporal sequencing. It provides semiotic rationale for how episodes develop from static single pictures (dependent on verbatim memory) to events whose frames reflect a deictic and sequential character—superseding the consciousness inherent in autonoesis. Empirical evidence will trace children’s event memory—first iconic and static, and later characteristic of increasingly more complex interpretants which specify directional and logical relations, and memory sources. The signs which promote episodic thought are indexical in nature, given their largely relational character. They incorporate deictic projections of the self in diverse orientations, entering into different participant slots inherent to the event. Notice of the latter entails the influence of index to apprehend the spatial, participatory, and temporal directionality within and across event frames. This progression requires a rudimentary consciousness of aspectual features (telicity, dynamicity), as well as an appreciation for the events’ purposes/goals. Anticipating how, where, and when events conclude is critical to realizing the event’s purpose/goal, since, according to Bauer 2006: 384, it constitutes the basis upon which episodes are constructed.

This paper presents an experimental system for remote communication between road users and traffic signs. Implemented solution consists of two modules: a transmitter (traffic sign), including novel system for remote waking-up by the passing vehicle with use of the quasi-passive (biased) diode detector circuit, and a receiver (vehicle), which is responsible for wake-up signaling and interpreting received messages. Both modules use Wi-Fi protocol operating in 2.4 GHz ISM band for sending data, and OOK signaling in 868 MHZ ISM band for sending wake-up signals. The paper provides theoretical analysis, description of design challenges and chosen solutions, and finally, laboratory measurements as well as the results of tests conducted in the systems’ target environment with a moving vehicle, confirming correct operation of the system.

Reliable, remote pulse rate measurement is potentially very important for medical diagnostics and screening. In this paper the Videoplethysmography was analyzed especially to verify the possible use of signals obtained for the YUV color model in order to estimate the pulse rate, to examine what is the best pulse estimation method for short video sequences and finally, to analyze how potential PPG-signals can be distinguished from other (e.g. background) signals. The presented methods were verified using data collected from 60 volunteers.

Research of semiotic aspects Lithuanian military air navigation charts was based on the semantic, graphic and information load analysis. The aim of semantic analysis was to determine how the conventional cartographical symbols, used in air navigation charts, correspond with carto-linguistic and carto-semiotic requirements. The analysis of all the markings was performed complex and collected by questionnaire were interviewed various respondents: pilots, cartographers and other chart users. The researches seek two aims: evaluate information and graphical load of military air navigation charts. Information load evaluated to calculate all objects and phenomenon, which was in 25 cm² of map. Charts analysis showed that in low flight charts (LFC) average information load are 4 – 5 times richer than in the operational maps. Map signs optimization on LFC has to be managed very carefully, choosing signs that can reduce the load of information and helps for the information transfer process. Graphical load of maps evaluated of aeronautical maps is not great (5 – 12%) and does not require reduction the information load and generalization of charts. Air navigation charts analysis pointed that not all air navigation sings correspond carto-semiotic requirements and must be improved. The authors suggested some new sings for military air navigation chart, which are simpler, equivalent to human psychophysical perception criteria, creates faster communication and less load on the chart.

The aim of this paper is to analyse and interprete the prose text "Vor der Zunahme der Zeichen" by the young, German-speaking writer who as a child fled from the civil war in Sri Lanka. The paper provides an analysis of the contingency of language signs (like homeland, descent, native language, identity) which is a function of the experience of flight, exile, and live in the globalized and electronic media-dominated world. The central role in the novel is played by the relation between death and literary language and its communicative and perception function.

The paper presents an experimental stand for testing the front car camera S-CAM with embedded image recognition systems. The camera sends CAN messages these are converted to USART messages by microprocessor based system. The messages are interpreted by MATLAB script on the basis of database of traffic signs in accordance with Polish Road Code. The testing stand is mainly aimed for educating students interested in the fields of electronics and technologies related to automotive branch, as well. The second objective is a research on efficiency of traffic sign recognition system being one of functionalities of S-CAM camera. The technical specification of testing stand, its functionality and limitations were also discussed. The bench operation was illustrated with examples of stiff images, animation and real movies.

The aim of the paper is to present the procedure of non-standard road signs and markings implementation in Poland to improve road safety and traffic performance of road infrastructure. The authors investigated the following cases: road and its surroundings’ perception and understanding improvement; warning of increased risk of accidents ; road works; speed management and ITS. The procedure was developed on the basis of interdisciplinary research, including: observation of drivers behaviour in real traffic; comparative crash analysis on sections with and without non-standard signs or markings; surveys on the understanding signs and marking; driving simulator experiments. As a result of the research, an implementation procedure for non-standard signs and markings, in the form of flowchart, was developed. In the designed procedure the following study of non-standard signs can be distinguished: questionnaire studies, eye tracking tests and driving simulator tests. The choice of the test method depends on the preliminary assessment of sign understanding, based on the results of the questionnaires. Moreover, thresholds for the declared understanding level, which determines the selection of additional tests to be done prior to the implementation of the sign, are given. The guidelines for conducting tests, analysis and monitoring of implementation were described as well.

The author paints a personal and often critical image of three cities — those, which he is the most familiar with and which are particularly dear and close to him. Despite being familiar with tens of the most renowned cities in the world, the author has selected fully familial examples, which he has had and continues to have personal ties. Throughout their histories, they have been subjected to dramatic events. In terms of spatial creation, they underwent — and continue to undergo-fluid, hybrid, ambivalent and often controversial transformation. They have also been treated implicitly, as subjectively-presented models of cities in general — as well as of their fate and evolution. The author considers the city to be — perhaps — the greatest expression of human culture and civilisation.

This paper discusses the influence of different sign conventions for strains and stresses, i.e. the solid mechanics sign convention and the soil mechanics sign convention, on the form of governing partial differential equations (the static equilibrium equations and the continuity equation) used to describe the wave-induced cyclic response of a poro-elastic seabed due to propagation of a sinusoidal surface water-wave. Some selected analytical solutions, obtained by different authors and published in specialist literature in the form of complex functions describing the wave-induced pore-fluid pressure, effective normal stress and shear stress oscillations in the seabed, have been analysed and compared with each other mainly with respect to different sign conventions for stains and stresses and also with regard to different orientations of the positive vertical axis of the two-dimensional coordinate system and different directions of surface water-wave propagation. The performed analyses of the analytical solutions has indicated many inaccuracies, or even evident errors and exemplary mistakes of wrong-signed values of basic wave-induced response parameters (the shear stress in particular), thereby disqualifying these solutions and their final equations from practical engineering applications. Most of the mistakes found in the literature must be linked to authors’ lack of understanding and consistency in an uniform application of a certain sign convention for strains and stresses in the soil matrix at both stages of mathematical formulation of the governing problem and correct interpretation of equations of the final analytical solution. The present paper, based mostly on a thorough literature review, ought to draw attention and arouse interest among coastal scientists and engineers in proper identification and use of the existing analytical solutions to the wave-induced cyclic seabed response – solutions which differ very often in the applied sign convention for stresses in the soil matrix.
