Classification of noisy vehicles from unsupervised measurements
Authors: Peeters Bert , Kuijpers Ard
Published: February 2023

The NEMO-project (https://nemo-cities.eu/) aims to identify noisy and polluting road and rail vehicles, using remote sensing technology. Noise levels from individual road vehicles are measured from the roadside, in normal traffic. Road authorities may use these data to enforce noise
limits, to limit access to Low Emission Zones or to influence driving behaviour. Whether a vehicle is a 'high noise emitter' is a complex question, as the noise level depends on vehicle type and condition, driving style, weather and location-specific characteristics. From a legal perspective,
the question may be answered in relation to type approval noise limits, or in relation to local noise disturbance regulations. Within NEMO, a classification model is developed from a large dataset of unsupervised pass-by noise measurements, from different locations. The model labels noisy
vehicles based on the noise measurements, technical vehicle data, driving conditions, and external factors. Several modeling and machine learning techniques were evaluated, to find the most accurate solution. This paper presents the results, and it looks forward to how the technological solution
could be applied to enforce regulations, leading to a reduction of traffic noise annoyance.
Noise mapping from above
Authors: Fay Endre
Published: February 2023

In the case of noise modelling preparation of industrial plants, if the client does not have the required quantity and quality of information and data for the proper outcome, we have to produce them for ourselves. In such instances, field survey is essential to obtain the desired data.
In this paper, it is shown how to create the necessary digital terrain (DTM) and surface (DSM) models for the noise modelling in case they are not available. The implementation of the task was solved by photogrammetric survey obtained as the result of a drone (UAV) flight operation and its
data processing. The aim is to produce a file that can be imported into the noise mapping software used in the project. On the generated orthographic photo of the study area the exact position of the noise sources can be marked in the horizontal plane. In vertical plane terms, the surface
model will help us to determine the height of the noise sources and the relevant objects. Then, using an appropriate software, a shape file can be generated and imported into the noise mapping software and as the goal, the noise modelling can be performed.
A theoretical study on the interplay of thermoacoustic modes with Helmholtz dampers in a longitudinal combustor
Authors: Wang Yichen , Yang Dong , Zhu Min
Published: February 2023

Thermoacoustic instabilities often present in gas turbine combustors, especially in land-based heavy-duty gas turbines. Normally, thermoacoustic modes can be classified into two sets: acoustic mode and intrinsic mode (ITA mode). Low order network models are usually used to study thermoacoustic
instabilities and passive control methods such as liners and Helmholtz dampers are often used to suppress these instabilities. The addition of Helmholtz dampers could suppress the original thermoacoustic modes. Meanwhile, it could also introduce a new mode, the eigenfrequency of which is related
to the parameters of the Helmholtz damper, including its resonant frequency and neck mean flow Mach number. The damping effects depend on the system parameters and could be different on the two categories of original thermoacoustic modes. Based on a rational design, both original modes can
be controlled by one damper. The new mode introduced by the damper could interplay with original modes to form new exceptional points with certain parameters. In that case, the eigenfrequency and mode shape of original modes could be vastly influenced. The theoretical results will be verified
by numerical simulations.
Contribution analysis of road noise with transfer path analysis based on neural network
Authors: Park Uyeup , Kang Yeon June
Published: February 2023

This paper introduces a new approach to transfer path analysis (TPA) combined with neural network technique. To obtain a large amount of operational data for training the neural network model, various operating conditions are considered, and the long term time domain data is converted
into complex-valued frequency domain data according to the acquisition block. The number of layers and nodes of the model are determined by considering the physical characteristics of the system, and hyper-parameters such as learning rate and momentum are adjusted to improve convergency and
efficiency. The reliability of the model is verified by comparing the estimated contribution and transmissibility with the existing methods. Unlike the existing TPA methods, only the operational data is needed to perform the neural network based TPA. This proposed method reduces the cost of
measurement step such as impact test to identify the propagation paths of the noise.

Published: February 2023

The building envelope plays a critical role in providing acoustic and thermal comfort. However, in different environmental conditions such as different noise levels and climate, the design process becomes more complex. The aim of this study is to evaluate the performance of building
envelope options in terms of acoustic and thermal performance. In this paper, it is desired to make a comparison of scenarios that meet the limit values of acoustic and thermal requirements recommended by the regulations in Turkey. Calculations have been made for a 4m x 4m bedroom with high
sensitivity level affected by traffic noise in Istanbul. Simulations have been executed in condition for 30%,50% transparency ratio, with brick, aggregated concrete, and aerated concrete block opaque components, and double glazing, double laminated glazing transparent components. The sound
insulation value of proposed facades DnT,A,tr (dB), and the total energy consumptions (heating and cooling) Q (kWh) have been calculated. The scenario set up with aggregated concrete block and double laminated glazing transparent component achieved high performance in terms of acoustic and
thermal comfort conditions. This study shows that the importance of acoustic and thermal performance should be considered together for more effective building design in accordance with user needs.
Modal Decomposition Analysis of Bluff-Body Stabilized Lean Premixed CH4/H2/air Flames Based on LES Data
Authors: Kutkan Halit , Amato Alberto , Campa Giovanni , Tay-Wo-Chong Luis
Published: February 2023

Unsteady flow and flame dynamics of bluff body stabilized CH4/H2/air premixed flames are investigated numerically with LES and modal decomposition techniques. Energy ranked and frequency dependent modes are identified with proper orthogonal (POD), spectral proper orthogonal (SPOD) and
dynamic mode decompositions (DMD). Flow and flame coherent structures are extracted based on the axial velocity and heat release rate contours. Two cases, namely 100% CH4/air (V-flame) and 43.4% CH4 + 56.6% H2/air (M-flame), are selected for the analysis. Each case is acoustically excited
in large eddy simulation (LES) with harmonic excitation signals at distinct frequencies and with a broadband excitation signal, to produce snapshots for modal decomposition analysis. In POD, the frequencies of the relevant modes are extracted with the discrete Fourier transform (DFT) of time
coefficients, while in SPOD and DMD the extracted modes are frequency dependent by nature. Results are compared and commented.
Raytracing in Galerkin Boundary Integral form
Authors: Emthyas Amal , Hargreaves Jonathan
Published: February 2023

Raytracing is an established method for computing the late-time part of room impulse responses. But it has the drawback that only very crude Monte Carlo models of boundary scattering and diffraction are possible to include without losing its attractive computational cost scaling. This
happens because higher-resolution models of these processes output multiple child rays for every parent ray received, making the number of rays grow with reflection order. An emerging solution is so-called 'Surface-Based' Geometrical Acoustics. Here the distribution of rays arriving at a boundary
is mapped onto a predefined set of spatial elements and angular interpolation functions, producing a vector of coefficients. Re-radiation of subsequent reflections is then a matrix multiplication, with the steady state solution being solvable via a Neumann series. Since rays only every propagate
one reflection order before being collected, diffraction and scattering process that cause them to multiply can be included without issue. Here we present a new formulation based on a Galerkin Boundary Element Method (BEM). A unique feature is its ability to readily change interpolation functions,
so their effect on accuracy and convergence can be assessed. In this preliminary work, it is verified against an Image Source Model for a rectangular room.
Parameter identification of two coupled oscillator model for pure intrinsic thermoacoustic instability
Authors: Wildemans Roeland , Kornilov Viktor , de Goey Philip , Lopez-Arteaga Ines
Published: February 2023

Thermo-acoustic instabilities are a well-known problem in combustions systems. In general, the type of these modes can be divided in two categories: (i) modes with an acoustic origin and (ii) modes with an intrinsic thermo-acoustic (ITA) origin. It is an challenging task to observe
the ITA modes experimentally. Therefore, a setup with a burner in an acoustic embedding with close to anechoic up- and downstream terminations is required. In previous research we introduced such a setup and conducted an experimental bifurcation analysis on the dominant pure ITA mode. In this
bifurcation analysis, we observed that for increasing upstream velocity the flames loose stability through a supercritical Hopf bifurcation and subsequently exhibit limit cycle, quasi-periodic and period-2 limit cycle oscillations. The quasi-periodic oscillations were characterized by low
frequency amplitude and frequency modulation. In this research we present a phenomenological model consisting of two coupled oscillators that is able to reproduce all the different experimentally observed regimes. This model consists of a nonlinear Van der Pol oscillator and a linear mass-spring-damper
oscillator, which are nonlinearly coupled to each other. Furthermore, we executed a parameter identification of the model and concluded that the model is able to describe the experimental data quantitatively well.

Due to the increase of electric motor cars for preventing spread of carbon dioxide, noise atmosphere inside the car compartment is more important for the perception of tire-pavement noise. This paper describes the impression of pattern noise created by the tire thread pattern under
real running condition. Our impression on tire-pattern noise is more prominent if the peak level of the pattern noise together with its frequency location and width of the peak. This paper deals with our impression on tire pattern noise how our impression vary with its peak level and frequency
location.
Reduced basis methods with parameterized boundary conditions for room acoustics

Published: February 2023

Room acoustic simulations can be performed by means of numerical methods, which typically solve the wave equation in an enclosure using discretization techniques. These methods provide high-fidelity solvers that include all the wave phenomena but are computationally costly. This paper
presents the potential of a reduced basis method for simulating room acoustics when the boundary properties are changed iteratively, e.g., design changes in rooms where different boundary properties are simulated, which increase the computational cost when using traditional high-fidelity solvers.
The presented framework allows reducing the computational burden by applying reduced basis methods and solving the problem in a reduced low-dimensional subspace where the absorption properties of complex boundary conditions are parameterized, e.g., the thickness of a porous material. The potential
of the proposed framework is analyzed in terms of computational efficiency, accuracy and storage requirements. We show a computational reduction of two orders of magnitude for a 2D case with an upper frequency of 2 kHz and three orders of magnitude for a 3D simple case with an upper frequency
of 1 kHz showing a potential of having an increase in terms of speedup when increasing the size of the domain. The storage requirement for a 2D case with an upper frequency of 8 kHz is 10.8GB while for a 3D case with an upper frequency of 1 kHz is 8GB.
Outlook for the ISO 22955: Acoustic quality of open plan offices
Authors: Le-Muet Yoan , Chevret Patrick , Bonzom Thomas , Brocolini Laurent
Published: February 2023

The ISO 22955 standard " Acoustic quality of open plan offices " was published in may 2021. It aims to provide principles, descriptors, and measurement methods to characterize acoustics, which are easy to use and correspond to the perception of the acoustical environment by
the occupants of the spaces. The scope of the standard is the acoustics of open-plan offices and, more specifically, cognitive effects of noise, i.e. acoustic comfort and noise disturbance in association with the activity. After more than a year of use of the standard, this document proposes
to take stock of it and to identify potential paths of reflection for a possible future revision. Among the points of discussion considered, are the consequences of the evolution of office work, activities and concepts in the tertiary sector (flex office, co-working, teleworking, etc.), and
their implication on acoustic quality. Another fundamental matter is the relevance of the indicators used in the standard and the associated required values.

Published: February 2023

Kyiv Metro was opened in 1960 and became the first metro system in Ukraine. From then until the beginning of the 21st century it was developing without considering the acoustic comfort of its passengers and employees. Increased levels of noise and vibration in public transport are mostly
ignored, although they are certainly recognized as the reasons for increasing the harmfulness of work for metro employees. The present report analyzes noise levels at metro stations depending on their design features. There are several main types of stations in the Kyiv metro: deep-lying,
shallow-lying, as well as above-ground stations. For all types of underground stations, there are options both with and without sound-absorbing finishes. Also, during the construction of the newest stations of the Kyiv metro, vibration isolation systems were used for the construction of the
permanent way were used. Within this study, sound pressure levels were measured on the platform at stations of various types. These measurements made it possible to establish a significant influence of the shape of the station vestibule, the presence of sound-absorbing finishes in it, as well
as the vibration isolation of the permanent way, on the objective and subjective parameters of acoustic comfort for passengers and employees of the subway.

Authors: Domazetovska Simona , Pecioski Damjan , Gavriloski Viktor , Mickoski Hristijan
Published: February 2023

The advances of artificial intelligence approaches for automatically extracting and classifying disturbing sounds have great potential and application in the development of smart cities. In this paper, an urban sound event classification system based on deep learning technologies has
been created by using the MEL-frequency cepstral coefficients as feature extractors and the Convolutional Neural Networks as classifiers. The designed system was trained and tested using the UrbanSound8K dataset which resulted in high classification accuracy of 92.67% of the tested results.
In addition to this, validation of unknown sound events was applied. Furthermore, we propose the creation of a stand-alone system capable of recording and classifying sounds within an urban environment and sending the classification data to the cloud. The implementation of such units could
result in real-time sound classification which can be used in smart cities based on the Internet of Things technology. According to this, an IoT smart city framework using AI for urban sound classification was proposed. The created system could find its use in many applications by making contribution
in creating a feasible and deployable real-time sound classification system.
Results from The Quiet Project - UK Acoustic Community's response to Covid-19
Authors: Kowalik Henry , Dance Stephen , McInyre Lindsay
Published: February 2023

The COVID-19 Lockdown created a new kind of environment both in the UK and globally, never experienced before or likely to occur again. A vital and time-critical working group was formed with the aim of gathering crowd-source high quality baseline noise levels and other supporting information
across the UK during the lockdown and subsequent recovery period. The acoustic community were mobilised through existing networks (UK Acoustics Network, Association of Noise Consultants, and Institute of Acoustics) engaging private companies, public organisations, and academics to gather data
in accessible places. A website was designed and developed to advertise the project, provide instructions and to formalise the uploading of noise data, observations, and Soundscape feedback. The data was collected at 99 locations by 80 acousticians (64 male, 16 female) using professional grade
calibrated instrumentation with 83% of measurements including spectral data. The locations were spread across the British Isles covering 19 urban, 61 suburban, and 19 rural sites. The Lockdown 1 dataset consisted of a total of 1.6 GB of measurements and material (video, photos) covering 834
days between 1st April and 14th July 2020. This makes the award winning Quiet Project the largest ever noise and soundscape database ever recorded. As a government-funded research project the databank will be made publicly available to assist future research.

Published: February 2023

With the advent of COVID, the wearing of face covering has been obligatory in both medical and everyday life. This paper describes three experiments undertaken to establish the effect of face coverings on speech sound power, speech directivity and speech intelligibility. The experiments
used two different approaches acoustic measurements and word scores. The face coverings assessed were a 'standard blue' surgical mask, a typical fabric mask, and a plastic transparent visor. The results showed that non-native English speakers had by far the most difficulty in comprehending
the English language speech when face coverings were worn in speech intelligibility tests, as measured using phonetically balanced word lists. All the masks were found to noticeably affect speech intelligibility, with the surgical mask having the least detrimental effect. The results are also
compared to objective measurements of their physical acoustics characteristics to establish their performance.
Advancements in autonomous detection of high noise emitters in road traffic
Authors: Kirchhoff Nikolas , Ertsey-Bayer Maximilian , Männel Manuel
Published: February 2023

Noise pollution is an increasing problem in densely populated areas with high traffic flow. The NEMO project (Noise and Emissions Monitoring https://nemo-cities.eu/) is funded by the EU to develop a system that is capable of detecting high emitters in terms of noise and air pollutants
to prosecute vehicle owners. To this end, a fully autonomous noise measurement system was developed and tested on several test locations, both unsupervised and supervised. This paper describes the advancements in autonomous measuring of traffic noise and specifically addresses the problem
of reliable noise source detection in dense traffic streams. While the correct localization of the source is of great importance, it is not yet enough to measure the correct sound pressure level. We therefore propose a method to estimate the influence of nearby noise sources, i.e. closely
driving additional vehicles, that disturb the sound signal of the vehicle of interest and correct for it. This algorithm has been applied on several test locations. Using these insights, we will discuss the benefits and possibility of the integration of such a system in the near future.
Habitats: Managing the Ecological Impacts of Noise on Wildlife Habitats for Sustainable Development
Authors: Waddington David , Wood Mike , Davies Bill , Young Rob
Published: February 2023

The objective of the Habitats project is to integrate research in the fields of ecological impacts and of environmental noise to develop management tools and processes to enable sustainable development. Rapid population expansion and economic development against the backdrop of climate
and biodiversity crises presents major global challenges. Global society is dependent on ecosystem services, underpinned by biodiversity. In the UK alone, these ecosystem services are valued at £761 billion/year and human noise impacts will significantly degrade that value unless managed
appropriately. We can no longer consider nature to be separate from our economy and society, it needs to be part of business, cultural and economic decision making. The Habitats project is leading the development of an international industrial and academic network to research and explore new
ways and new technologies to better measure, understand and model the effects of noise on wildlife habitats. However, current noise pollution legislation is focused on humans; despite policy aspirations, there is no systematic approach to assessing, regulating, or mitigating noise impacts
on wildlife. This paper will review the scientific evidence available for underpinning environmental noise legislation, regulation, and policy development for managing the ecological impacts of noise on wildlife habitats.
On homogenized ribbed-panel model for SEA analysis
Authors: Mejdi Abderrazak , Alimonti Luca , Gardner Bryce
Published: February 2023

This paper presents an investigation into a recent model of homogenized rib-stiffened panels. An equivalent panel model is developed from the skin and the stiffeners of the panel. In this case a space-harmonic-based approach is used, and first-order shear deformation theory is employed
to account for the wavefield's in-plane/out-of-plane coupling effect in the skin. The panel's stiffeners interact with the skin through internal forces and moments at the connections. A periodic FE mesh is then used to compute the wave dynamics and the results are used to develop the required
terms to solve for vibro-acoustic results in Statistical Energy Analysis (SEA). This process is used to predict the vibro-acoustic response of an aircraft structure. The SEA results are compared with detailed FE models of the rib-stiffened aircraft structure.

Modulation of Hanle magnetoresistance in an ultrathin platinum film by ionic gating
Authors: Maruyama Yuu , Ohshima Ryo , Shigematsu Ei , Ando Yuichiro , Shiraishi Masashi
Published: February 2023

Hanle magnetoresistance (HMR) is a type of magnetoresistance where interplay of the spin Hall effect, Hanle-type spin precession, and spin-dependent scattering at the top/bottom surfaces in a heavy metal controls the effect. In this study, we modulate HMR in ultrathin Pt by ionic gating, where the surface Rashba field created by a strong electric field at the interface between the ionic gate and Pt plays the dominant role in the modulation. This finding can facilitate investigations of gate-tunable, spin-related effects and fabrication of spin devices.

The Effect of the Absence of a Premeditated Murderer on the Punishment in Imamieh Jurisprudence (With a View on Article 435 of the Islamic Penal Code)
Authors: Hosseinzadeh Abdolreza , Azizollahi Hojat
Published: February 2023

One of the issues that have been raised in jurisprudence texts for a long time is the non-execution of qisas for the lack of the murdered due to his escape or sudden death. In this case, some believe in turning qisas into Diya and they have resorted to the principle of respect for Muslim blood, Authority verse and hadiths; however, these reasons have been criticized by others because according to these reasons, the avenger of blood are entitled to the murderer’s soul not his possessions. Therefore, they cannot be a reason for the necessity of Diya and the narrations are exempt from the assumption of their authenticity. Others reject qisas and Diya because the compromise of the parties is a prerequisite for converting qisas to Diya, which would not be possible if the murderer is absent. However, since the traditions of proof of the Diya have the necessary authority, they cannot be ignored and the Diya is not rejected. Therefore, in accepting the distinction between escape and sudden death because the conversion of qisas into Diya is contrary to the principle and in cases of contrast to the principle, it is necessary to refer to the subject of the hadith i.e. the escape of the murderer. Many of the jurisprudents might be considered in agreement with this statement because proponents of the Diya, affirm the Diya in the event of an escape and those who believe in voiding Diya, reject Diya in the event of death. However, since the Diya is intervening substitute, if the murderer comes back, the right to qisas is reserved for the avenger of blood. Finally, Article 435 of the Islamic Penal Code can be criticized and amended for the lack of distinction between escape and natural death as well as for the transmission of qisas to Diya for intentional non-murder crimes.
A Pragma-Discoursal Study of News Conflict in Arabic Media
Authors: Abu-Krooz Hasan
Published: February 2023

News Conflict is an old-new topic that has been scrutinized and studied from different angles. Yet, no attempt of a comprehensive pragma- discoursal treatment or analysis of the pragmatic elements of news discourse has been spotted. Thus, this work concerns itself with the attempt of designing a rather comprehensive pragma-discoursal approach to investigate News Conflict. This incorporates investigating the most observable pragma-discoursal means employed by two ideologically contradicting news channels, namely, Al-Jazeera and Al-Ittijah Satellite Channels in viewing news and events; identifying the major pragma-discoursal devices exploited by Al-Jazeera and Al-Ittijah Satellite Channels for achieving their ideologically-contradicting aims. In light of these aims the study hypothesizes that Foregrounded Themes, Modality, Lexical Cohesion, Collocation and Pragma-rhetorical Tropes are the most readily observable Collocation and Foregrounding are the major processes manifested in presenting news and events that are used by both channels under investigation

A construction project is a form of activity that takes place within a certain period of time and with certain resources to achieve results in the form of buildings or infrastructure. Problems that occur in a construction project are determined by the suitability of time, cost, and quality agreed in the contract documents. The road handling project is one of the areas of construction projections that are also fighting for the project. The road maintenance program in Indonesia is implemented by the Ministry of Public Works and Public Housing in the form of a preservation project with a long segment scheme. The long segment scheme has performance indicators that can assess the performance of road preservation projects so that the success of road preservation projects can be measured. This underlies this research to analyze the Critical Success Factor (CSF) on the success of road preservation projects. The Partial Least Square – Structural Equation Modeling (PLS – SEM) analysis method was used in this study to analyze the CSF performance of a road preservation project with a long segment scheme. The results of the analysis show that the Critical Success Factor that has an impact on the success of the road preservation project with the long segment scheme is the standard quality test factor with a value of 0.371 having the greatest impact. Overall, the CSF factors of the performance of the road preservation project with the long segment scheme have quite an effect (moderate) on the success of the project in the performance indicator slogan, namely with a proportion value of 47.5%. In conclusion, overall the Critical Success Factor elements of road preservation project performance with a long segment scheme are quite influential on project success in the performance indicator slogan, namely with a proportion value of 47.5%.

Abstrak: Jerami padi biasanya tidak dimanfaatkan oleh penduduk. Sebagian besar hanya dibuang begitu saja dan hanya sebagian kecil digunakan sebagai pupuk organik. Desa Mangsang merupakan desa yang memiliki sawah dan penduduknya banyak yang memiliki ternak sapi. Ketika musim kemarau, penduduk umumnya mengalami kesulitan dalam menyediakan pakan untuk ternak sapi mereka. Kurangnya pengetahuan dan minimnya akses informasi membuat penduduk setempat tidak begitu mengetahui jika fermentasi jerami padi dapat digunakan sebagai pakan alternatif dan dapat disimpan dalam waktu yang lama. Tujuan dari pengabdian ini untuk membantu penduduk dalam mempersiapkan pakan alternatif bagi sapi terutama dimusim kemarau. Metode kegiatan yang digunakan yaitu dengan pendekatan teori dan praktek. Kegiatan yang berlangsung selama 3 hari dilakukan dengan cara penyampaian materi kemudian praktek pembuatan. Ground truth merupakan metode yang digunakan dalam kegiatan ini dimana pengetahuan dihasilkan pengalaman bukan dari teori. Hasilnya pemahaman materi yang awalnya hanya 40% menjadi 90% dan praktek yang awal hanya 49% menjadi 100%. Peningkatan yang sangat signifikan ini akibat dari adanya pola pemberian materi yang diikuti langsung dengan praktek sehingga tujuan dari kegiatan ini dapat lebih mudah dicapai. Memang benar kegiatan seperti ini akan meningkatkan pengetahuan dan kreativitas penduduk.Abstract: Rice straw is usually not utilized by the population. Most of it is just thrown away and only a small portion is used as organic fertilizer. Mangsang Village has rice fields and many residents own cattle. During the dry season, residents generally experience difficulties in providing feed for their cattle. Lack of knowledge and lack of access to information makes local residents not really know if fermented rice straw can be used as an alternative feed and can be stored for a long time. The purpose of this service is to help residents in preparing alternative feed for cattle, especially in the dry season. The method of activity used is with a theoretical and practical approach. Activities that lasted for 3 days were carried out by delivering material and then practicing making. Ground truth is a method used in this activity where knowledge is generated by experience not from theory. As a result, the understanding of the material which was initially only 40% became 90% and the initial practice was only 49% to 100%. This very significant increase is due to the pattern of providing material followed directly by practice so that the objectives of this activity can be more easily achieved. It is true that activities like this will increase the knowledge and creativity of the population.

Published: February 2023

A presente pesquisa parte da compreensão da relação entre Educação Popular e direitos humanos através da Interculturalidade e Decolonialidade. Fundamentada sobre os conceitos de Interculturalidade, Educação Popular e Direitos Humanos, repensando assim, de que forma contribuem para a libertação dos sujeitos e construção de uma Educação Humanizadora, frente as contradições do sistema capitalista opressor. Entre outras coisas, a Educação Popular e Direitos Humanos torna-se física e palpável, no momento em que é construída pelos sujeitos, na intenção de preservarem suas formas de vida, resistência e luta. Em momentos sombrios como estamos vivendo-nos de 2015-2022, discutir acerca de Educação Popular e Direitos Humanos, nos leva a compreender uma luta histórica marcada por conquistas e retrocessos desde 1960, nas quais, temos resultados práticos e palpáveis de uma articulação movida pelo âmbito da Educação e Movimentos Sociais.
Teatr francuski w Warszawie za Augusta III
Authors: Korzeniewski Bohdan
Published: February 2023

Artykuł zawiera odpisy afiszów teatralnych z 1762 roku, które autor sporządził przed II wojną światową na podstawie oryginałów pochodzących ze zniszczonych w czasie wojny zbiorów Załuskich z Biblioteki Narodowej. Są to afisze francuskiej trupy aktorskiej Albaniego, która występowała w Warszawie w latach 1762 i 1763. We wprowadzeniu autor określa charakter i badawczy potencjał tych dokumentów. Afisze pełniące zarazem rolę programów i ulotek reklamowych drukowane były w językach francuskim i polskim, zawierały informacje na temat tytułu i autora wystawianej sztuki, cen biletów, terminów przedstawień, nie podawano w nich natomiast nazwisk aktorów. Zdaniem autora zestawienie tych informacji z innymi materiałami z epoki pozwala na odtworzenie repertuaru, sposobu organizacji występów oraz warunków, w jakich funkcjonował teatr. Treść afiszów skłania także do rewizji poglądów na temat życia teatralnego w czasach saskich. Wynika z nich, że występy teatru francuskiego miały regularny charakter, a Albani wystawiał w Warszawie ambitny repertuar: Molière'a, Marivaux, Regnarda, Destouchesa, Dancourta, Brueysa, La Fontaine’a, a także – po raz pierwszy w Polsce – Le Père de Famille Diderota.
Polska premiera «Mieszczanina szlachcicem» w roku 1687
Authors: Lewański Julian
Published: February 2023

Artykuł dotyczy polskiej inscenizacji Le Bourgeois Gentilhomme Molière’a z 1687 roku. Autor publikuje i dokładnie opisuje odnaleziony w zbiorach Biblioteki Ossolineum we Wrocławiu program tego przedstawienia zawierający synopsis sztuki w języku polskim. Odtwarza także okoliczności wydarzenia: wydobywa z tekstu informacje, dzięki którym można stwierdzić, że przedstawienie odbyło się w Rydzynie w Wielkopolsce, w pałacu polskiego arystokraty Rafała Leszczyńskiego. Stawia kilka hipotez, które wymagają dalszych badań. Przedstawienie w pałacu Leszczyńskich w Rydzynie mogło być jedną z imprez królewskiego teatru dworskiego lub występem amatorskim. Autor przypuszcza, że inicjatywa należała do samego Leszczyńskiego, który nie tylko dobrze znał Francję i jej kulturę, lecz także prowadził stałą korespondencję z Ludwikiem XIV, uważającym go za jednego z najwybitniejszych polityków w Polsce. Podkreśla ponadto, że polska inscenizacja była jedną z pierwszych w Europie.
