Problems in the ability to write experienced by students are strongly influenced by various factors, including the teacher's factor in choosing a learning model. The selection of learning models is highly dependent on the competencies that students will achieve. For this reason, in learning short story writing, a model must be chosen that can make it easier for students to write with various efforts, including intermediary to continue the story through crisis orientation in the storyline. To do that, this study implements the Problem Based Learning model.  This study aims to determine the implementation of the problem-based learning model in learning to continue the end of crisis-oriented short stories. The research method used is a mix method.' This research was carried out in class XI of SMA Handayani 1 Pameungpeuk. The instrument used in this study was an essay test. The instruments are categorized as vaid and reliable after statistical testing (validity and reliability). The calculation of this study is through the average test of the pretest and posttest classes, knowing the max value and minimum value, and testing the hypothesis with a paired t-test sample. The results showed that student activities increased with an average pretest score of 44.90 and an average posttest of 78.10, and the results of the gain hypothesis test were probability values or Signs. (2-tailed) 0.00<0.05. The magnitude of the impact on the improvement of continuing crisis-oriented short stories is shown by the results of hypothesis tests that state differences in data on pretetst and posttest results and show the results of increased learning by looking at the average of each activity. Thus the problem-based learning model can be used as an alternative learning model used to improve the ability to write short stories.

Published: January 2023

There are several problems in Islamic education during the current pandemic. In contrast to other types of education, Islamic education has a special emphasis on transmitting religious values ​​and morality into the behavior and actions of children. Islamic education not only has the burden of responsibility for growing knowledge itself, but also character behavior in children based on religious values. One of the biggest influences to deal with such investigations is the family. Family education is very important because of the Government's Emergency Community Activity Restriction (PPKM). The family must be able to become a laboratory for Islamic education for students in the context of habituation and discipline in life attitudes. In a role like this, the family is like the closest educational institution for children, with parents as the main teacher, without eliminating the role of the teacher and the actual educational institution. This study uses a qualitative method. The data in this paper are sourced from interviews, as well as literature relevant to the writing. There are three sources in this paper who were selected based on the purposive sampling method. The results of the interviews, as well as the relevant literature were then analyzed and showed that parents play an important role in shaping the character of students to become complete human beings, namely acting as educators (educators), facilitators, motivators, companions and supervisors, as well as role models for children (uswatun khasanah). Therefore, parents have a greater challenge in supervising and supervising children because of the use of gadgets that are often used by children

Education is an absolute necessity in a country. The country needs quality education to build superior human resources. The decline in socio-economic aspects of society, moral decadence, low and unhappy quality of life is caused by the Indonesian education system has not been successful in efforts to build the nation. Minister of Education Nadiem Makarim initiated the concept of Independent Learning to revolutionize the education system in Indonesia. Islam has a strong educational direction and has not changed in the Qur’an. This study aims to determine the comparative study between the vision and objectives of Islamic education in QS. Al-Jumu'ah verse 2 with the vision of education of the Independent Learning program. The research method used is library research. Data analysis and comparison techniques are presented in the form of descriptive writing. The results showed that the purpose of Independent Learning education in the philosophical theory of progressivism & constructivism is the same as the goal of QS Islamic education. Al-Jumu'ah verse 2 in the interpretation of Al-Misbah. Meanwhile, the goal of Independent Learning in holistic humanistic philosophical theory is the same as At-Thabari's opinion in his book of interpretations. However, Independent Learning has not touched the aspect of religiosity as the vision of Islamic education stated by Ibn Katsir in his verse interpretation. Thus Independent Learning as a concept that determines the direction of Indonesian education is not perfect, because it has not included elements of religiosity in it, namely the vision of education in Islam. The vision deals with the balance between worldly and ukhrawi matters

A Organização para a Cooperação e Desenvolvimento Econômico (OCDE) adentra os projetos e políticas educacionais difundidas no Brasil, contribuindo para a ascensão da lógica neoliberal na educação. Nesse viés, este artigo de abordagem qualitativa e análise documental tem como objetivo discutir as relações estabelecidas entre as políticas de avaliação no Brasil, os Organismos Internacionais, e a cultura da performatividade oriunda dessas relações. Nesse sentido, a accountability educacional, em voga em vários países, ganha cada vez mais espaço, ao operacionalizar e integrar a concepção de avaliação, prestação de contas e responsabilização. O conceito de performatividade abordado no texto descreve a cultura da performatividade como a busca pelos desempenhos, invadindo e transformando as individualidades e subjetividades do professor, da educação e da sociedade. Como resultados, destaca-se o forte papel da OCDE como organismo transnacional impactando nas políticas nacionais e na produção de uma transformação e uniformização do conceito de qualidade educativa. Para concluir, o texto propõe a busca por alternativas para pensar uma corresponsabilidade de todos os envolvidos no processo educativo e na reafirmação do papel do professor e da escola pública em um projeto de responsabilização participativa, democrática e de qualidade negociada.

Este artigo, produzido no âmbito da Tarefa PISA nos Media, do projeto A success story? Portugal and the PISA (2000-2015) torna visíveis discursos de artigos de opinião publicados no jornal Público, um jornal português de referência, diário e de caráter generalista. Pretende ser uma contribuição não só para analisar alguns dos artigos de opinião publicados, como também para identificar e revelar processos sociais inerentes a cada um deles numa lógica de prática social, através da Análise Crítica do Discurso (ACD), de acordo com a perspetiva desenvolvida por Fairclough (2001, 2012). Salienta-se que a operacionalização da ACD dos artigos estudados foi publicada em António (2022), como forma de a tornar clara, verificável e discutível. A sua inclusão neste artigo poderia colocar em causa o ritmo do texto e levá-lo para um caráter de relatório ou documento de trabalho. Este artigo tem, portanto, o objetivo de contribuir para o estudo da ACD enquanto teoria: “A ACD, na minha visão, é muito mais uma teoria que um método, ou melhor, uma perspetiva teórica sobre a língua” (Fairclough, 2012, p. 307), de valorizar os artigos de opinião publicados enquanto instrumentos e objetos de investigação académica, e de propor uma resposta possível à questão de partida: o PISA é uma história de sucesso? Na parte final do texto, surge a provocação. Se não fosse uma história de sucesso, não seria um tema para os comentadores, em suma uma moveable feast.
System approach to assessing dynamic states of technical objects: elements of concept of dynamic invariants
Authors: Eliseev Andrey , Kuznecov Nikolay Konstantinovich , Mironov Artem Sergeyevich
Published: January 2023

The scientific and methodological base is being developed within the framework of systems theory and system analysis in application to the tasks of assessment, control and formation of dynamic states of technical objects, the design schemes of which are mechanical oscillatory systems with concentrated parameters. In the context of the fundamental problems of the theory of system studies of forced movements under deterministic disturbances there are considered the problems, whose solutions are aimed at developing a methodological approach to assessing the dynamic states of technical objects operating under coherent vibration loads. The purpose of the study is to develop a method for evaluating, controlling and forming dynamic states of the objects under harmonic force loads. It is assumed that mechanical oscillatory systems formed by a solid body performing small steady-state oscillations relative to the position of the static equilibrium can be used as calculation schemes of the technical objects. To construct mathematical models, Lagrange formalism, Laplace integral transformations taking into account zero conditions and structural methods are used, which make it possible to consider mechanical oscillatory systems as dynamically equivalent structural schemes of automatic control systems. The dynamic state of an object is assessed by using a transfer function, which in the physical sense represents the interpretation of a dynamic compliance. The amplitude-frequency characteristics used to assess the dynamic state of the object present a parametric family, for which the first parameter is the coefficient of connectivity of external force disturbances, and the second parameter is the coordinate of the point for which the dynamic accuracy is defined. An infinite family of amplitude-frequency characteristics is regularized due to the introduction of dynamic invariants, which can be considered as generalized dynamic states of mechanical oscillatory systems. To determine the dynamic invariants of a family of amplitude-frequency characteristics, taking into account two parameters, a map of dynamic invariants is constructed, which divides the plane of parameters into disjoint sets using boundaries. A theorem is proved to determine the explicit analytic expressions of these boundaries.
Structural-linguistic approach to the description of spectrogram of electromagnetic radiation spectrograms generated by computing technology
Authors: Tretiakov Igor Aleksandrovich
Published: January 2023

In this paper, the solution of an urgent scientific and technical problem in the field of information security is considered – the problem of detecting electromagnetic radiation generated by computer technology, within the framework of a structural and linguistic approach to the analysis of experimental data. The implementation of the stage

of assigning segmented sections of spectrograms of symbols of some alphabet corresponding to certain types of behavior is considered in detail. As well as the implementation of the analysis stage of the received sequences of symbols. A model of morphological grammar construction and a mechanism for generating texts that differ little from the correct ones are described. The grammar formation stage was implemented in the Python 3.7 programming language. The choice of this programming language is justified by its cross-platform nature, low entry threshold, as well as wide application: from automation of mathematical calculations and machine learning, to the development of web applications. Also, one of the advantages of this language is the availability of many high-quality libraries, including those used for current development. A statistical experiment was conducted to evaluate the effectiveness and accuracy of the developed algorithms. An estimate of the probability of the correct classification of linguistic chains of experimental spectrogram curves into the desired groups and a general assessment of the accuracy of the correct determination of all curves into the desired groups is given. As a result of the application of a structural-linguistic approach to the problem of detecting electromagnetic radiation generated by computer technology, it can be concluded that the obtained linguistic descriptions of the studied spectrograms represent short and reliable rules for their analysis and allow for high accuracy in automated mode to determine deviations in the observed spectra from the specified standards.
Hybrid technique of speech signal noise reduction for video conferencing system
Authors: Belov Sergey Valerevich , Katunin Sergey Sergeevich
Published: January 2023

The article focuses on the problem of audio signal quality during video conferences. The effect of noise on the quality and intelligibility of the speech signal is described. Analysis of the noise reduction in the audio signal in real time has been carried out. The main problems arising in the digital processing of the audio signal in real time are highlighted. General methods of reducing the noise are considered and the disadvantages of classical methods are revealed. The problem of eliminating noise with a variable frequency band by using classical noise reduction methods is formulated. There is substantiated the need for creating a hybrid noise reduction technique by using machine and deep learning methods to eliminate both static noise and noise with complex and variable spectral characteristics. The main approaches to solving the problem of noise reduction in real time are highlighted, namely the approach with recognition and elimination of noise and the approach with voice recognition and elimination of sounds that differ from the speech signal. A noise reduction algorithm based on an approach with recognition and elimination of noise is described. Optimization of the algorithm is proposed by decomposing the spectrum of the input signal according to the Bark scale. A recurrent neural network is proposed as a tool for implementing a noise reduction algorithm. The formats of the input and output data of the neural network as well as the format of the training data are defined. A model for adjusting parameters and rules for adapting the noise reduction algorithm to the specific operating conditions is described. A hybrid noise reduction technique combining classical noise reduction methods and methods based on a recurrent neural network is proposed. A scheme of a hybrid technique has been developed. A method of testing the effectiveness of the noise reduction technique is proposed.

Published: January 2023

The article considers the possible modernization of the well-known aeronautical radio station in order to increase the noise immunity of radio communications. Uninterrupted noise-immune radio communication between the aircraft and the air traffic controller is an important factor in ensuring flight safety. The radio station provides voice (telephone) communication and telecode digital communication, with voice information transmitted in analog format this causes radio interference distorting the transmitted messages. Increased noise immunity can be achieved by transmitting voice information in a digital form, the special noise protection measures relevant only for digital transmission being applied. Antinoise coding and pseudo-random software frequency hopping can be used as the preventive measures. The task was set to investigate the problem of modernizing a well-known aviation radio station with the minimal changes in its configuration. There has been proposed a method providing the digital radio communication with modification of a prefabricated aeronautical radio station. A digital speech signal developing in this case is provided due to the resources of the radio station used to transmit the telecode information. The information transfer rate increases from 16 to 128 kbps, which leads to the increased frequency deviation and, as a result, to the expanded signal spectrum. The noise immunity of the system was also assessed in a communication range of 100 km: the signal power, signal-to-noise ratio, noise spectral density at the receiver input, transmitting antenna directivity were determined. Based on the results of the calculations, it was inferred that due to realizing the proposed measures a manifold multiplication of the required power of the jamming

In the course of 2006-2007, the author carried out an investigation on the fly fauna at Gyűrűfű. Any flies have not been recorded from this area so far. As many different fly habitats can be found in 1 km2 sample area so the fauna is rich in fly species. The author identified fly species from only the following families: Syrphidae, Tachinidae, Culicidae, Bombyliidae, Stratiomyidae, Tabanidae, Conopidae, Acroceridae, Athericidae, Coenomyiidae, Rhagionidae, Scenopinidae, Therevidae, Xylomiidae, Xylophagidae. Altogether 450 species of above mentioned families are known from the area.

In the frame of the Bidiversity Day events organized in Gyűrűfű (Baranya County, Hungary) we showed the presence of 7 amphibian and 5 reptile species in a 1 square km area designated for the survey. This number of species may nearly complete, only the Smooth Snake (Coronellea austriaca) has not been found during the 3x48 hours quick search although it is putatively presenting in the region. Amongst the observed species the yellow-bellied toad (Bombina variegata) is the rarest one of the Hungarian herpetofauna. Most probably its population is a marginal one of a much larger stock living in the Zselic region. A few kilometers to the south the wetland habitats are occupied by red-bellied toad (Bombina bombina).

During the 6 days (2 days yearly) of this project the three authors collected 143 spider species from the area of Gyűrűfű village, from about 1 km2 area. These 143 spider species correspond to about 20% of the total spider species known in Hungary. Out of these 143 species 2 species were found to be new for the Hungarian fauna: Sintula corniger (Blackwall, 1856), Zora paralella Simon, 1878. This report will also discuss the dominance and disturbance tolerance categories of spider species native in Hungary. In addition some rare species will be introduced in details.

Thirteen psocid species have been found in occasion of the surways carried out in the framework of the Biodiversity Days at the village Gyűrűfű. Two of them (Graphopsocus cruciatus and Valenzuela flavidus) - which are common on large part of Europe - were greatly abundant. Other five psocids (Stenopsocus stigmaticus, Kolbia quisquiliarum, Philotarsus parviceps, Elipsocus moebiusi and Mesopsocus laticeps) are known only from a few other territories of Hungary, and - therefore - are valuable in point of view of natural protection.

Partifecske (Riparia riparia) állományfelmérések a Dráva-mentén, 2000-2008 között
Authors: Fenyősi László
Published: January 2023

This study summarizes the results of Sand Martin (Riparia riparia) population surveys along river Drava. The investigations started in 2000, along the 67 kilometre long river section stretching from Bélavár to Szentborbás (199-132 river kilometres), with the aim of following population trends of Sand Martins (Riparia riparia). During the survey, the number of breeding pairs was established by taking 60% of the number of nest holes counted (Szép 1991). The size of the breeding population along the 67 km long reach between Bélavár and Szentborbás numbered 2370 pairs in 2000 which then decreased to 1116 pairs in 2002. Population size in the sample area then reached its peak with 3489 pairs in 2006, then dropped significantly again. The difference between the largest and smallest population size is more than threefold. Within the period of 2000-2002 the highest proportion of nest colonies was those with less than 200 nest holes (72.8%, 62.5% és 84.6%), in 2003- 2006 those with more than 200 nest holes (62.5%, 62.5%, 57.2% és 77.77%), and in 2007-2008 again those with less than 200 nest holes (74.97% és 66.66%). Besides these monitoring studies, from 2003 we extended our surveys onto the entire common Croatian-Hungarian Drava section (237-70.5 river km) and onto two nearby sand pits. Thus, with these data, the number of breeding Sand Martin pairs in the surveyed areas was 3786 in 2003, 3788 in 2004, 4125 in 2005, 4729 in 2006, 4806 in 2007, and 3333 in 2008. We have found that both the size of the breeding population and breeding success are influenced predominantly by water levels of the Drava. Flood waves and high water periods within the breeding season (May-June) can wash away nest holes or even colonies that are located lower down, as was observed most strikingly in 2004 and 2008.
Long-term monitoring of Himantoglossum adriaticum H. Baumann population in Keszthely Hills, Hungary
Authors: Bódis Judit , Molnár Edit
Published: January 2023

Long-term monitoring of populations contributes to the better understanding of population dynamics of species. A population of the orchid Himantoglossum adriaticum H. Baumann was monitored in Keszthely Hills in western Hungary during the period 1992-2008. To assess reproductive output in each year, the number of flowering individuals, as well as the number of flowers and fruits produced per plant were recorded. The reproductive traits studied (except the number of flowering plants and seedpods) did not varied considerably, they showed low temporal variability over years, while the other two characteristics mentioned had high temporal variability. Mean number of flowers produced per plant over all years was 31. Fruitproduction was often low or zero. Significant correlations between the rate of fecundity and any of the flowering traits could not be found. Years with high fruit-production do not coincide with years of great number of inflorescences. Thus, the number of inflorescences measured in any one year can not be used as a substitute for reproductive performance measurements. Years with high fruit-set may be able to insure long-term survival of the population.
