Opis:
A new method for determining optimum dimension ratios for small rectangular rooms has been presented. In a theoretical model, an exact description of the room impulse response was used. Based on the impulse response, a frequency response of a room was calculated to find changes in the sound pressure level over the frequency range 20-200 Hz. These changes depend on the source and receiver positions, thus, a new metric equivalent to an average frequency response was introduced to quantify the overall sound pressure variation within the room for a selected source position. A numerical procedure was employed to seek a minimum value of the deviation of the sound pressure level response from a smooth fitted response determined by the quadratic polynomial regression. The most smooth frequency responses were obtained when the source was located at one of the eight corners of a room. Thus, to find the best possible dimension ratios, in the numerical procedure the optimal source position was assumed. Calculation results have shown that optimum dimension ratios depend on the room volume and the sound damping inside a room, and for small and medium volumes these ratios are roughly 1 : 1.48 : 2.12, 1 : 1.4 : 1.89 and 1 : 1.2 : 1.45. When the room volume was suitably large, the ratio 1 : 1.2 : 1.44 was found to be the best one.

Opis:
W artykule przedstawiono opis specyfiki pracy wychowawcy w świetlicy szkolnej na podstawie dostrzeżonych w literaturze przedmiotu czynników określających jej istotę. W związku z przyjętą perspektywą interpretacyjną, świetlica szkolna została scharakteryzowana jako miejsce, które z definicji odgrywa istotną rolę w procesie wspomagania rozwoju dziecka, a proces ten wspiera specyfika pracy wychowawcy w świetlicy szkolnej. Do analizy miejsca, jakim jest świetlica, wykorzystano koncepcję Jerzego Nikitorowicza. Odnosząc się do wyodrębnionych przez niego „pograniczy”, dookreślono, jak wygląda praca wychowawcy w świetlicy szkolnej w perspektywie czynników istotnych dla analizowania świetlicy w kontekście każdego z pograniczy. Pozwoliło to uzyskać nowe ujęcie opisywanego miejsca.
This article presents a description of the specificity of a teacher's work in the common room based on the factors determining its essence, noticed in the literature on the subject. Due to the adopted interpretative perspective, the common room has been characterized as a place that by definition plays an important role in the process of supporting a child's development, and this process is supported by the specificity of the teacher's work in the common room. The concept of Jerzy Nikitorowicz was used to analyse the common room. Referring to the "borderlines" identified by him, it was specified what the work of the teacher in the common room looks like in the perspective of factors important for analysing the common room in the context of each borderline. It allowed to obtain a new perspective of the described place.

Opis:
Large venues and auditoriums are commonly associated with their astounding architecture. Their acoustic quality is an essential factor in its qualification as a great and functional, or a badly designed place. However, acoustics is often overlooked during the design stage of a building due to the complexity and high cost of the measurements involved. For this reason, it is important to explore more accessible ways to implement acoustics evaluations. The aim of this work is to compare typical experimental measuring methods and the use of mobile devices to assess the acoustic quality of a room. These measurements are contrasted with the software simulation of the same acoustical space. The results show that the mobile system can be used for professional measurements with low restrictions in the frequency range of interest of this study (90 Hz to 4000 Hz).

Opis:
Reverberant responses are widely used to characterize acoustic properties of rooms, such as the early decay time (EDT) and the reverberation times T20 and T30. However, in real conditions a sound decay is often deformed by background noise, thus a precise evaluation of decay times from noisy room responses is the main problem. In this paper this issue is examined by means of numerical method where the decay times are estimated from the decay function that has been determined by nonlinear polynomial regression from a pressure envelope obtained via the discrete Hilbert transform. In numerical experiment the room responses were obtained from simulations of a sound decay for two-room coupled system. Calculation results have shown that background noise slightly affects the evaluation of reverberation times T20 and T30 as long as the signal-to-noise ratio (SNR) is not smaller than about 25 and 35 dB, respectively. However, when the SNR is close to about 20 and 30 dB, high overestimation of these times may occur as a result of bending up of the decay curve during the late decay.

Opis:
An Orthodox church as a building expresses the Eastern Orthodox spirituality – all the details and general aspects have a deep and philosophical meaning. The architecture, being an illustration of the character of the Orthodox Church liturgy, has become a natural component of the cultural landscape of Poland and Eastern Europe. Acoustic research into Orthodox churches has so far been marginalized. Up to now, only a few churches of this type have been studied. The article is a review of the acoustic environment of churches in Poland. Churches, differing in terms of size, architectural style and other quantities, were chosen and acoustic measurements were made. The results of the measurements have been analyzed and collated. In particular, a detailed analysis and comparison was made for reverberation time as a function of frequency, due to the largest differences in this parameter between the rooms.

Opis:
This paper proposes a new approach for calculating the impulse response of room acoustics. Impulse response provides unique characterization of any discrete lineartime invariant (LTI) systems. We assume that the room is a linear time-invariant system and the impulse response is calculated simply by sending a Dirac Impulse into the system as input and getting the response from the output. Then, the output of the system is represented as a sum of time-shifted weighted impulse responses. Both mathematical justifications for the proposed method and results from simulation software developed to evaluate the proposed approach are presented in detail.

Designing a proper acoustical environment—indispensable to speech recognition—in long enclosures is difficult. Although there is some literature on the acoustical conditions in underground stations, there is still little information about methods that make estimation of correct reverberation conditions possible. This paper discusses the assessment of the reverberation conditions of underground stations. A comparison of the measurements of reverberation time in Warsaw’s underground stations with calculated data proves there are divergences between measured and calculated early decay time values, especially for long source–receiver distances. Rapid speech transmission index values for measured stations are also presented.

Frequent causes of ship detentions by port authorities are abnormalities of marine power plant functioning. Each extended ship lay time inport results in a was te of ship operating time thus costs rise to ship owners. This is connected with improper marine power plant management. In order to avoid this, a ship engineer should have at his disposal a computer aided system supporting him in managing the marine power plant. Such a system can be worked out on the condition that a mathematical model, which represents the decision - making proces s ofan engineer has been built. This workpresents approach to the problem ofone aspect in engine room managing what is operating task scheduling for the staff. The chief engineer is responsible for all engine room operating processes. He must make the plan for all activities to secure his correct operation. The use separately of several mathematical methods is not so effective, as then, when they are the put-upon in frames in coherent system and conduct as a consistent procedure. The main problem In this paper was create the mathematical model of system to assigning operational tasks in engine room, which would permitted to choice the optimum variant of tasks schedule.

Opis:
In recent years we have interviewed members of the audience after musical performances and asked them to evaluate the acoustics of the concert halls. A group of "music lovers" (with a high level of musical training and experience) and "acousticians" (with a wide knowledge of the physical characteristics of sound transmission) also attended each performance and answered the same questions as the general public. This group thereby served as a control group when evaluating surveys of the general public. In this paper, the results obtained when analyzing these control group surveys are presented. This analysis shows that a common vocabulary exists between music lovers and acousticians when rating a hall, although the grouping of the questions for each factor depends on the training of the respondents.

Opis:
A theoretical method has been presented to describe sound decay in enclosures and simulate the room impulse response (RIR) employed for prediction of the indoor reverberation characteristics. The method was based on a solution of wave equation with the form of a series whose time-decaying components represent responses of acoustic modes to an impulse sound source. For small sound absorption on room walls this solution was found by means of the method of variation of parameters. A decay function was computed via the time-reverse integration of the squared RIR. Computer simulations carried out for a rectangular enclosure have proved that the RIR function reproduces the structure of a sound field in the initial stage of sound decay sufficiently well. They have also shown that band-limitedness of the RIR has evident influence on the shape of the decay function and predicted decay times.

Opis:
Accurate definition of boundary conditions is of crucial importance for room acoustic predictions because the wall impedance phase angle can affect the sound field in rooms and acoustic parameters applied to assess a room reverberation. In this paper, the issue was investigated theoretically using the convolution integral and a modal representation of the room impulse response for complex-valued boundary conditions. Theoretical considerations have been accompanied with numerical simulations carried out for a rectangular room. The case of zero phase angle, which is often assumed in room acoustic simulations, was taken as a reference, and differences in the sound pressure level and decay times were determined in relation to this case. Calculation results have shown that a slight deviation of the phase angle with respect to the phase equal to zero can cause a perceptual difference in the sound pressure level. This effect was found to be due to a change in modal frequencies as a result of an increase or decrease in the phase angle. Simulations have demonstrated that surface distributions of decay times are highly irregular, while a much greater range of the early decay time compared to the reverberation time range indicates that a decay curve is nonlinear. It was also found that a difference between the decay times predicted for the complex impedance and real impedance is especially clearly audible for the largest impedance phase angles because it corresponds approximately to 4 just noticeable differences for the reverberation metrics.

Opis:
The purpose of the study was to compare auditory judgments of sound clarity of music examples recorded in a concert hall with predictions of clarity made from the impulse response signal recorded in the same hall. Auditory judgments were made with the use of two methods: by rating sound clarity on a numerical scale with two endpoints, and by absolute magnitude estimation. Results obtained by both methods were then compared against the values of clarity indices, C80 and C50, determined from the impulse response of the concert hall, measured in places in which the microphone was located during recording of music examples. Results show that auditory judgments of sound clarity and predictions made from the C80 index yield a similar rank order of data, but the relation between the C80 scale and perceived sound clarity is nonlinear. The data also show that the values of C80 and C50 indices are in very close agreement.

The discussion refers to the findings of other researchers of chrematonymy, who consider this area of onomastics to be a cultural and linguistic phenomenon. Such theoretical background enables me to propose a three-part model of the chrematonym of an economic activity of a natural person on the basis of the names of rehabilitation/physiotherapy rooms. A detailed analysis of the analysed examples is presented in the second part of the paper.

Opis:
Virtual or active acoustics refers to the generation of a simulated room response by means of elec- troacoustics and digital signal processing. An artificial room response may include sound reflections and reverberation as well as other acoustic features mimicking the actual room. They will cause the listener to have an impression of being immersed in virtual acoustics of another simulated room that coexists with the actual physical room. Using low-latency broadband multi-channel convolution and carefully measured room data, optimized transducers for rendering of sound fields, and an intuitive touch control user in- terface, it is possible to achieve a very high perceived quality of active acoustics, with a straightforward adjustability. The electroacoustically coupled room resulting from such optimization does not merely produce an equivalent of a back-door reverberation chamber, but rather a fully functional complete room superimposed on the physical room, yet with highly selectable and adjustable acoustic response. The utility of such active system for music recording and performance is discussed and supported with examples.

In this paper, the computer modelling application based on the modal expansion method is developed to study the influence of a sound source location on a steady- state response of coupled rooms. In the research, an eigenvalue problem is solved numerically for a room system consisting of two rectangular spaces connected to one another. A numerical procedure enables the computation of shape and frequency of eigenmodes, and allows one to predict the potential and kinetic energy densities in a steady-state. In the first stage, a frequency room response for several source positions is investigated, demonstrating large deformations of this response for strong and weak modal excitations. Next, a particular attention is given to studying how the changes in a source position influence the room response when a source frequency is tuned to a resonant frequency of a strongly localized mode.

Opis:
Numerous studies have shown that teachers often speak louder in classrooms because of the acoustic properties of the spaces. To improve the acoustics in classrooms, it is necessary to develop relevant acoustic criteria. Existing evaluation scales for parameters of room acoustics have been developed on the basis of studies of adults for a variety of languages (e.g. Dutch and English). One of the issues still not fully recognized is the effect of the respondents’ language and age on the results of speech intelligibility tests. The aim of the study was to recognize the possibility of applying some international guidelines for room acoustics developed on the basis of adult studies to classrooms in Polish schools. This paper presents a study of the speech intelligibility of Polish-speaking children (10–13 years old) in conjunction with parameters of room acoustics. It also compares studies of speech intelligibility for other languages. The study confirmed a relationship between the results of speech intelligibility tests and speech transmission index STI for classrooms with varied acoustics. It also showed that the results of Polish word test are similar to results of English tests (Anderson, Kalb, 1987; Jacob et al., 1990).

The article discusses the semiotic parameters of the locus of the study room in the Russian novel from the second half of the 19th century. It outlines the socio-cultural context that makes this locus topical in the works of the Russian novelists from the epoch after the reforms. The given examples of presence of the study room in the novels of I. Turgenev, I. Goncharov, F. Dostoevsky and L. Tolstoy are interpreted in several principle aspects: – objects in the composition and its selection – the relation character – material detail – semantic transformations and their motivation.

Opis:
The main problem in the measurement of airborne sound insulation is the measurement of the sound power radiated by the barrier, in practice performed by measuring the sound pressure level and the acoustic absorption in the receiving room. Large variations of the sound pressure level in a reverberation room indicate the presence of dominating strong standing waves, so that it becomes necessary to install diffusing elements. In ISO 10140, the limits have been defined in which the reverberation time at frequencies at and above 100 Hz should be included. Sometimes, however, in the case of rooms with a large volume, obtaining the required parameters is difficult and sometimes even impossible. It should then be checked whether the measured sound insulation depends on the reverberation time. The paper presents the results of sound insulation measurements at various reverberation time lengths in subsequent stages of diffusing elements installation in the receiving room. An analysis of diffusing materials amount and arrangement influence on the uniformity of the sound pressure level distribution and reverberation time in the room as well as the value of the measured sound insulation was carried out. Uncertainty of sound insulation measurement with partial uncertainties was adopted as a criterion supporting the assessment of the obtained results.

Opis:
Reflecting structures placed over the stage in auditoria and concert halls should provide sound reflection in a way that enhances sound emission from the stage without causing acoustic defects in the interior. Model studies conducted by the authors were used to determine the relative level of sound reflection by reflecting structures as a function of frequency for a number of geometric configurations and materials. Analysis of the results allowed drawing conclusions about the effect of modifications of the ceiling over the reflecting panels on the quality of the sound reflected from them. It was shown that modification of the ceiling over the reflecting panels by employing highly sound absorbing materials significantly improved the characteristics of the reflected sound. Also, certain configurations of elements located in the space under the ceiling should be avoided, as the experiments indicated the occurrence of adverse acoustic effects.

Opis:
A modal representation of a room impulse response has been used to formulate expressions for low-frequency sound field in rooms of arbitrary shape. Based on theoretical results, a simulation program has been developed to predict a sound pressure distribution and a room transfer function for rectangular enclosure having walls covered by a material of complex impedance. Calculation results have shown that changes in the wall reactance entail a substantial modification of a sound pressure distribution. Furthermore, an influence of wall reactance on the room transfer function was investigated and it was discovered that a change in a reactance sign causes a shift in frequencies of modal vibrations excited in the room.

Opis:
Currently used procedures in room acoustics measurements are not automated. Particularly in medium-sized and large areas they require a lot of time and intensive labour which directly translates into an increase in the measurement cost. Introduction of an automated system would increase efficiency of the measurements, and therefore could present both practical and scientific benefit. The paper presents initial feasibility study for designing a system that permits the measurement of selected acoustic parameters for any choice of three-dimensional grid of measurement points throughout the volume of the room. The system will utilize an autonomous probe attached to a blimp, and will be able to measure and analyze acoustic characteristics of the rooms. The article discusses the initial choices of the system elements, starting from the general idea, through the mechanical design and control procedures, the software that controls positioning and flying of the probe, up to the automation of the measurement procedure and its possible impact on the acoustic field.

Parameters related to the reverberation time, background noise, and intelligibility (both physical measurements of different parameters [Definition (D-50) and STI] and speech tests used to study the subjective response of listeners) were studied. The measurements were compared with some recommendations from the literature and, considering that speech was the main use of the studied rooms, with the intelligibility results. Some different recommendations for reverberation times taken from the literature were analysed. The intelligibility results obtained from the measurements were also compared with the intelligibility results that were determined by the speech tests.

Acoustic quality of a classroom is a term proposed to describe acoustic properties that contribute to a subjective impression received by a human, such as speech intelligibility, external noise, or vocal effort. It is especially important in classrooms, where suitable conditions should be provided to convey verbal content to students, taking into account their age. The article presents a method for assessing the acoustic quality of classrooms based on a single number global index and taking into account a number of factors affecting the outcome of the assessment. Partial indices are presented and their weights are proposed based on an analysis of factors determining whether a room meets applicable acoustic requirements. Results of the assessment of the acoustic quality carried out with the use of the developed method in selected classrooms are also presented.

Opis:
The aim of the text is to present the potential of Foucault’s concept of dispositive for interpreting the space of a child’s room. I look for arguments in favor of this proposal in the concepts of the place by M. Eliade, P. Ricoer, and Yi-Fu Tuan, who combine creating a place with the process of constructing human identity. In reference to them, I assume that a child can create his own identity only if he has a chance to transform the space available to him. The analysis of the history of children’s room shows, however, that his space has always been created as a result of adults’ practices aimed at educational goals. Thus, the children’s room can be treated as dispositif, serving the governmentality of child.

Opis:
Sound field parameters are predicted with numerical methods in sound control systems, in acoustic designs of building and in sound field simulations. Those methods define the acoustic properties of surfaces, such as sound absorption coefficients or acoustic impedance, to determine boundary conditions. Several in situ measurement techniques were developed; one of them uses 2 microphones to measure direct and reflected sound over a planar test surface. Another approach is used in the inverse boundary elements method, in which estimating acoustic impedance of a surface is expressed as an inverse boundary problem. The boundary values can be found from multipoint sound pressure measurements in the interior of a room. This method can be applied to arbitrarily-shaped surfaces. This investigation is part of a research programme on using inverse methods in industrial room acoustics.

Opis:
Ventilation and air conditioning systems are necessary for developing proper parameters of indoor environment in operating rooms. The main task of ventilation and air conditioning in those specific areas consists in creating desirable temperature, reducing the number of microorganisms and the concentrations of hazardous gases and substances in the air, as well as ensuring the proper direction of airflow. In Poland, indoor environment in operating rooms has to comply with the requirements set out in three regulations (Journal of Laws of 2002 No. 75, item 690, as amended, Journal of Laws of 2002 No. 217, item 1833, Journal of Laws of 2011 No. 31, item 158, as amended) and the document entitled "Guidelines for the design of general hospitals". Given insufficient accuracy of the abovementioned national documents, it is a common practice to use foreign standards, i.e. ASHRAE Standard 170-2013, DIN 1946-4: 2008 and FprCEN TR 16244: 2011. When considering the conditions for thermal comfort, it is important to bear in mind a close link between air flow velocity and air temperature. Air in the zone occupied by patients and medical staff must not cause the sensation of draft. Furthermore, air velocity should be sufficient to eliminate interference caused by the presence of people and other sources of heat. It should also reduce the turbulence level in the air in the operating room. Efficient functioning of ventilation and air conditioning was tested during treatments and operations carried out on three wards of a Warsaw hospital. Tests were performed with the participation of medical staff from various surgical units. They were asked to perform minor manual tasks to simulate work on the operating table, and to complete a questionnaire on subjective thermal sensation. The applied methodology is widely used during testing of general and local ventilation in public buildings. Air temperature, relative humidity, air flow supply and exhaust air from the operating room were deter-mined on the basis of VelociCalc 8360 and Testo 435 anemometers with a 3-function probe and 3 vane probes with the diameter of 16 mm, 60 mm and 100 mm. Throughout the study, microclimate conditions in the operating rooms were controlled by the EHA MM101 microclimate meter. Test results showed that the microclimate parameters met the requirements of the aforementioned documents. However, individual thermal sensations reported by the medical staff pointed to the lack of thermal comfort and, in extreme cases, e.g. when using lead aprons during operations, perception of the thermal environment as ‘very hot’. The efficiency and type of air distribution in operating rooms has a decisive effect on the results.

The impact of obesity on health, social care and the economy has long been established. Being obese or overweight increases the risk of developing a range of serious diseases including psychological disturbance, diabetes, heart disease, musculoskeletal disorders such as osteoarthritis and cancers that lead to premature disability and mortality. The good news is that overweight and obesity are largely prevent and /or control-able through losing weight strategies and fitting room can be an option for whom are observant about their surroundings. The fitting room is usually where the consumer makes their final evaluation about the products while assessing personal appearance, and finally deciding whether or not to purchase the garment. For some people, fitting room it is something to get through without visible or psychic damage and for some others is a horrifying place as they may suddenly realize how overweight or obese they are that could be a challenging start to maintain a healthy body image in a life-changing journey. In fact, the changing room is inspired to provide some people with personal choices toward a desirable weight therapy through engaging in exercise and diet. Hence, fitting room while in shopping even for entertainment purposes is advised as a beneficial life - time decision in weight control and obesity may take place by individual in this way.

This paper offers an analysis of chrematonyms connected with the area of rehabilitation/physiotherapy, as represented by the names of non-public rehabilitation/physiotherapy rooms in Białystok. It discusses the structure of anthroponyms as distinct components of the names, the structure and semantics of their identifying parts, as well as the structure and semantics of the firmonyms proper. I discuss the variants and the structure of the chrematonyms, paying particular attention to the semantically hypertrophic names. I also present the role of non-semantic elements in the names of the firms. The analysis demonstrates that the chrematonyms connected with the area of rehabilitation/physiotherapy form a heterogenous group of onyms; they reflect the varied nature of the profession, the current lifestyle trends, as well as the current epidemiological and demographic tendencies.

One of the most frequently used methods of adjusting the room acoustics of concert halls is the temporary introduction of additional acoustic absorption in the form of acoustic banners. Banners are implemented in the form of fabric surfaces placed vertically or horizontally along the walls of concert halls. In practice, one or two layers of heavyweight fabrics are used, characterized by a high value of the sound absorption coefficient. Simplified methods of designing acoustic banners assume estimating the effectiveness of adjusting the reverberation time on the basis of the static theory. The paper presents the results of measuring the effectiveness of acoustic banners carried out in the concert hall. The possibility of tuning the interior acoustics was verified depending on the position of the banner in the room as well as the degree of its opening.

Opis:
Świetlica to instytucja o charakterze opiekuńczo-wychowawczym, będąca częścią integralną szkoły. Wypełnia zadania uzupełniające proces opieki i wychowania uczniów w czasie, kiedy czekają oni na rozpoczęcie zajęć dydaktycznych lub po zakończeniu tych zajęć. Zarówno opieka, jak i wychowanie oraz realizacja zajęć dydaktycznych w świetlicy szkolnej są działaniami odrębnymi. Mimo to w prawidłowo realizowanej pracy w ramach zajęć świetlicowych pozostają one we wspólnych zależnościach. Najważniejszym ogniwem dobrze funkcjonującej świetlicy jest osoba opiekuna-wychowawcy. Od jego kompetencji zależy to, jak odbierana jest rola świetlicy w oczach uczniów i ich rodziców. Wyniki przeprowadzonych badań świadczą o aktywnej postawie wychowawców świetlicy względem wychowanków.
Common room is an educational and care institution. It forms an integral part of a school. Its function is to complement the educational and care process of the pupils before or after their school classes. Care, education and conduction of classes in a common room are separate tasks. Nonetheless they are mutually dependent if the common room activities are implemented properly. The most important element of a well-functioning common room is a common room teacher. Its competence determines how the role of a common room is perceived by pupils and their parents. The results of the conducted research suggest an active attitude of common room teachers toward their pupils.

Opis:
Zabieg pomostowania aortalno-wieńcowego stanowi prawie 3/4 wszystkich zabiegów kardiochirurgicznych. Ta rozległa i skomplikowana operacja wymaga uczestnictwa wykwalifikowanego zespołu medycznego, którego niezbędną częścią są pielęgniarki instrumentariuszki. Posiadana przez nie wiedza teoretyczna i praktyczna oraz doświadczenie przyczyniają się do sprawnego przebiegu zabiegu. Do zadań pielęgniarki operacyjnej należy nie tylko instrumentowanie, ale również przygotowanie sali operacyjnej, narzędzi, kontrola sterylności materiałów, prowadzenie dokumentacji (przez pielęgniarkę pomagającą), wykonywanie opatrunków oraz odpowiednie postępowanie z narzędziami po zabiegu i oddanie ich do sterylizacji. Bardzo ważne jest również dbanie o bezpieczeństwo pacjenta, za które odpowiedzialni są wszyscy członkowie zespołu operacyjnego.
The coronary artery by-pass surgery accounts for almost 3/4 of all cardiosurgical procedures. This extensive and complicated operation requires the participation of a qualified medical team whose necessary part are nurse practitioners. Their theoretical and practical knowledge as well as experience contribute to the smooth operation of the procedure. The tasks of the scrub nurse include not only instrumentation, but also the preparation of the operating room, tools, control of sterility of materials, keeping documentation (by the nurse helping), dressing and proper handling of tools after surgery and putting them to sterilization. It is also very important to take care of the patient’s safety, for which all members of the operating team are responsible.

Opis:
En un estilo sumamente poético, reflexivo y deliberadamente fragmentario, Ricardo Romero construye en su novela un relato que tematiza, a través del mecanismo del extrañamiento, la delgada línea entre lo que se percibe como privado e íntimo y aquello que pertenece por completo al ámbito de lo público. Desde la visión subjetiva de un niño, La habitación del Presidente incursiona en el siniestro territorio de los espacios familiares, redescubriendo los recovecos aparentemente asépticos del mapa como espacios-otros, auténticas heterotopías instaladas en lo más profundo de la intimidad familiar y cotidiana. El extrañamiento del narrador en primera persona se proyecta en el lector, que se ve de pronto inserto en un universo muy similar al propio, pero con algunas reglas tácitas que encuadran al relato en la frontera con lo fantástico: la presencia en todas las casas de una habitación para el Presidente, la prohibición de los sótanos, la propia figura del Presidente y el aura de misterio que rodea la posibilidad inminente de su visita. La percepción de los espacios como ajenos, espacios-otros cargados de una semántica particular, es el principal mecanismo que sostiene la estructura de todo el relato.

Opis:
The statistics invariably show that most onboard fires originate in the engine room. In hazardous conditions, fires can spread to other rooms of the ship and cause the loss of human life, and can cause the ship to be out of service or lost completely. To prevent these serious consequences, the engine room crew should be aware of hazards and ways to prevent them. It is also advisable to support their routine activities and actions in critical situations with an appropriate management system. For this reason, a survey was conducted at the beginning of 2019 of engine room crew members employed by a European shipowner, as a contribution to an analysis of fire safety management. Based on the results of the survey, some of the elements of the fire safety management system of the ship engine room are described. A properly constructed system that is understandable and accepted by the crew is one of the most important factors in increasing fire safety on a ship. Familiarisation with adequate procedures can significantly contribute to the successful prevention of accidents. This paper also proposes a checklist based on suggestions by the crew, which may be helpful in onboard fire prevention.

Opis:
Games gain popularity as teaching tools. Escape rooms, however, are a novelty, with most authors focusing on their description rather than the analysis of effects of their utilisation. The objective of this paper is to analyse experiences of players partaking in an educational escape game, and to observe escape rooms from the viewpoint of a scholar interested in the efficiency of the tool. The research material consists of questionnaires filled in by research subjects and transcripts of structured interviews. Due to the relatively large sample (N = 258), it is possible to conclude from the gathered quantitative data that there has been a growth in the subjects’ knowledge.
Stosowanie gier jako narzędzi nauczania jest coraz popularniejsze. Jednak użycie escape roomów stanowi nowość i większość autorów koncentruje się raczej na opisie samego narzędzia niż na analizie efektów jego zastosowania. Celem artykułu jest analiza doświadczeń osób biorących udział w edukacyjnym escape roomie oraz spojrzenie z perspektywy badacza zainteresowanego skutecznością narzędzia. Materiał badawczy pochodzi z wypełnionych przez uczestników kwestionariuszy oraz transkrypcji wywiadów ustrukturyzowanych. Dzięki stosunkowo dużej próbie (N = 258) możliwe było stwierdzenie na podstawie danych ilościowych, że wiedza uczestników wzrosła.

Opis:
This paper presents the results of measurements of the sound absorption coefficient of auditorium seats carried out in the laboratory using two methods. In the first one, small blocks of seats in various arrangements were studied in a reverberation chamber to determine the absorption coefficient of an auditorium of infinite dimensions. The results were compared to the values of the absorption coefficient measured using the second method, which involved samples enclosed within a frame screening the side surfaces of other auditorium blocks. The results of both methods allowed for the assessment of the sound absorption coefficient of an auditorium of any dimensions while taking into account the sound absorption by the side surfaces. The method developed by the authors will simplify the currently known measurement procedures.

Opis:
A set of sound power assessments was performed to determine measurement precision in specified conditions by the comparison method in a reverberation room with a fixed position array of six microphones. Six blenders (or mixers) and, complementary, a reference sound source were the noise sources. Five or six sound power calculations were undertaken on each noise source, and the standard deviation (sr) was computed as “measurement precision under repeatability conditions” for each octave band from 125 Hz to 8 kHz, and in dB(A). With the results obtained, values of sr equal 1.0 dB for 125 Hz and 250 Hz, 0.8 dB for 500 Hz to 2 kHz, and 0.5 dB for 4 kHz and 8 kHz. Those can be considered representative as sound power precision for blenders according to the measurement method used. The standard deviation of repeatability for the A-weighted sound power level equals 0.6 dB. This paper could be used for house or laboratory tests to check where their uncertainty assessment for sound power determination is similar or not to those generated at the National Metrology Institute.

Opis:
Operating room is now a place or a magical environment where the suture irreplaceable, quiet and reliable tour guide patients and surgeons. There was a perception that communication with patients in operating theaters is very limited, respectively, rare and used much less than the wards, intensive care units and clinics, but it is not so. Communication during surgical interventions, whether among staff or patients is always individual. This depends mainly on whether the interventions under general, spinal or local anesthesia . This is a rather important fact, because it is derived from a method of communication between members of the operating team and the operations team and the patient. Communication is an important aspect of nursing activities. That is reason why the autors of the report focus on the specificis of nursing care in the operating room. Work in this field pats high demands on the nurse as the site of a professional, as well, as psychologicae, physical and emotionae. Inclusion of nurses in this work provides the same personal characteristics and skills.
