Authors: FLORÊNCIO ROBERTO REMÍGIO , Freire da Silva Lauriana Patrícia
Published: January 2023

O presente artigo é resultado de um estudo de análise textual, com o objetivo de construir algumas possibilidades de interpretação ligadas à conjuntura sociopolítica do Brasil no final da década de 1980, sob a visão de um expoente do rock nacional. Optou-se pelos poemas contidos em quatro letras de músicas compostas por Cazuza (1958-1990), que versam sobre o contexto da promulgação da Constituição (1988) e redemocratização. A escolha do artista foi intencional, tanto pela qualidade de sua obra quanto pela representatividade que ele incorporou na luta contra a hipocrisia social e estereótipos de comportamento. A temática ficou por conta das questões sociopolíticas, época de escândalos de corrupção, movimentos populares, declínio do Governo Militar e liberdade de expressão. As análises comprovam a relevância do artista no cancioneiro nacional, a força de seu discurso irônico-emotivo e a importância de se efetivar a criticidade através de textos de fácil acesso e que possam contribuir para a construção e percepção das diversidades culturais.

Published: January 2023

This study aims to find the effect of ternary blended: cement, fly ash (FA), and rice husk ash (ASP) on the compressive strength of high-strength concrete.  The composition of FA and ASP used for cement replacement were 0%, 10% ASP, 30% FA, 10% ASP+30% FA, 10% ASP+40% FA, and 10% ASP+50% FA.  The water-cement factor (FAS) and binder used are 0.3 and 500 kg/m3 fresh concrete, respectively.  The specimens used for compressive strength is cubes of 100×100×100 mm with tests at the age of 1, 3, 7, 28, and 56 days.  The results showed that the use of 10% ASP increased the compressive strength of the concrete compared to the control concrete but required more superplasticizers.  The use of 30% FA as a cement substitute showed a decrease in compressive strength compared to control concrete but reduced the use of superplasticizer.  The use of a combination of FA and ASP as a substitute for cement showed a decrease in compressive strength under control concrete and concrete using 30% FA.  The decrease in the compressive strength of concrete with the combination of ASP and FA is beyond the initial expectation.  This may be due to the disproportionate use of FA compared to ASP so that the reaction that occurs is not optimal to form calcium silicate hydrate (CSH).  However, the use of ternary blended cement, FA, and ASP still has added values which is better workability than without using FA.

Published: January 2023

Psychological tests are an important need in various spaces of human life. Not only related to matters of a clinical nature, psychological tests are also used in the workspace. Psychological tests are carried out as an effort to find out by knowing more about a person's personality. One of the methods used by psychologists is Kraepelin to get personality types. In practice, psychological tests in understanding an object, namely humans with all their attitudes and behavior, still use the old way. Psychological tests still use sheets or series of questions given to related objects and the calculation of results or assessments is still done manually. Errors in the assessment will affect the results so that it will lead to inappropriate perceptions. Making questions requires time and high accuracy, so the system is built using the Linear Congruential Method (LCM). LCM method is used to generate random numbers with better access time performance in terms of complexity and optimality. The 20 minute test application consists of 40 columns and 60 rows of questions with a time limit of 30 seconds for each column. The website-based Kraepelin test application can support all related parties, both the test organizers and test takers, to get real-time and accurate test results by applying the Kraepelin test using the LCM method. The implementation of the Kraepelin test is in accordance with the purpose of using the test, namely as a tool to measure aptitude (speed, accuracy, stability and work endurance). Based on the test results, the calculation of the score using the system will be faster with a calculation time of 2 seconds while the manual calculation is 5 minutes.

Peculiarities of Mass Migration of Ukrainians to Western European Countries after February 2022
Authors: Sobolieva Olena
Published: January 2023

Since February 24, 2022, when the Russian Federation launched a full-scale war against Ukraine and invaded Ukrainian territories from several directions, Ukraine has faced the biggest migration crisis since World War II. More than a third of Ukrainians were forced to leave their homes. For Western Europe, these events also caused the biggest migration crisis since the middle of the 20th century. According to the latest UN data, as of the end of October, there are currently at least 7,700,000 refugees in Europe, 4,300,000 refugees have received the status of temporary EU protection, or a similar status from non-EU countries. It is worth noting that it is difficult to establish the exact number of Ukrainian refugees. Ukrainians cross the border in both directions. Some people temporarily staying in the EU are not registered as persons in need of temporary protection, but stay there as tourists.Ukrainian migrants face a lot of problems in the host countries, namely lack of funds for living, lack of housing, labor difficulties, difficulties in learning local languages, problems with teaching children in local schools. Gradually, the processes of integration of Ukrainian refugees in different European countries are taking place. However, the issue of establishing intentions to return to their homeland is important. After all, reverse migration will affect the post-war development of Ukraine. An important factor is the fact that the vast majority of women with minor children were forced to leave their husbands in Ukraine. Most families will try to unite after the end of martial law and the ban on crossing the border for men. The main question will be which trend will prevail: women returning home with children or, on the contrary, men moving to their wives abroad.All these events require careful study in order to forecast the further development of the migration of the Ukrainian population.

Spring Calendar Rituals of the Medieval Ukrainians in Comparative Context
Authors: Rakhno Kostiantyn
Published: January 2023

The article deals with the manifestations of the phenomena of substratum origin in Ukrainian culture, which appeared as a result of the interaction of the Slavic ancestors of the Ukrainians with the Iranian-speaking nomads of the steppe. Thanks to it, the Ukrainians have a lot in common in their spiritual and material culture with the Ossetians, who are the direct descendants of the Sarmatians and Alans, as well as with the Persians, Tajiks, Kurds, and Pamirs. In particular, closeness can be traced in the spring calendar rituals. Ukrainian customs of the Velykden holiday, identified with Easter under Christianity, have a lot in common with the celebration of Nowruz holiday, which is the key for the Iranian world. This is especially evident when the data on medieval Ukrainian rituals is included. The French engineer and cartographer Guillaume Le Vasseur de Beauplan in his famous Description of Ukraine (1650) recorded the archaic moments of the Easter celebration. They relate to the obligatory exchange of colored and painted eggs for the holiday, as well as the ritual sprinkling of water on the Pouring Monday after Easter. The calendar rites and customs of the Ukrainians described by Guillaume Levasseur de Beauplan find exact correspondences in the New Year rituals of Iran recorded by the Europeans. The French jeweler Jean Chardin in 1686 and the Dutch artist and traveler Cornelis de Bruyn in 1704 recorded the Persian custom of giving painted or gilded eggs on Novruz, which was connected with ancient Iranian ideas about the egg as the root cause of all living things, and the Venetian Pietro della Valle, during his stay in Iran in 1617-1627, had the opportunity to observe the rite of pouring water on a special holiday after Nowruz. The Persians, Tajiks, Vakhans, Ishkashims, Shugnans, Kurds, and Ossetians followed these customs and rites, which have parallels with Ukrainian ones, in later times. The Ukrainian folklore image of the lord of evil chained in Hell, who is angered by the existence of Easter eggs, also finds correspondence in Persian Zoroastrianism and the pagan religion of the Ossetians.

Authors: Otroshko Liubov
Published: January 2023

The article analyzes and emphasizes the important role of the Ukrainian diaspora in the countries of Europe and North America, it continues to play after the full-scale invasion of Ukraine by Russian armed forces. The support of Ukrainians by the diaspora in the conditions of insidious and unprovoked military aggression of the Russian Federation against Ukraine and Ukrainians is characterized. In particular, the current state of studying the role of Ukrainians abroad in European and North American countries is presented. It is traced how the Ukrainian diaspora, with the help of governmental and non-governmental international humanitarian organizations, continues to support the Ukrainian state from the beginning of the military conflict and helps to overcome the consequences of the armed expansion of the Russian Federation. It was revealed that after the armed aggression of the Russian Federation on the territory of the Ukrainian state, the Ukrainian diaspora actively joined the struggle for the preservation of Ukrainian statehood, ethnocultural space, ethnic culture and identity. It is shown that Ukrainian communities abroad have undertaken informational, diplomatic, financial, humanitarian, military, cultural and social work. It has been found that Ukrainians abroad constantly accelerate the victory of Ukraine in the Russian-Ukrainian war actively supporting refugees and displaced persons, providing diplomatic and financial support through international and humanitarian programs and funds, finding temporary shelter, promoting the flow of military, medical and humanitarian aid to Ukraine, limiting infoterror in the media and cyberspace. It is substantiated that with the assistance of Ukrainians abroad, social and humanitarian aid centers operate both from volunteers and from international charitable organizations. It was highlighted that Ukrainian embassies, in close cooperation with Ukrainians abroad, actively spread knowledge about Ukraine, its past and present, thereby contributing to the further consolidation of Ukraine as a strategic partner state with a long history, rich culture and clearly defined European and North Atlantic perspectives.

Authors: Kireeva Natalya Yurievna
Published: January 2023

Specific theatricalization by means of musical expressiveness is manifested in modern choral music in many ways. The creation of a choral work focused on theatrical interpretation is connected with the solution by a composer of a number of artistic tasks when composing a musical score with director’s instructions. The aim of the article is to identify the means of expressing choral music in the field of theatrical art. The scientific novelty consists in presenting a general picture of the state of modern choral theatre with a reflection of its inherent communicative expressive means. As a result of the study, the author comes to the conclusion that choral performances have great communicative capabilities, since the complex of expressive means used helps to simultaneously draw several semantic lines of the work.
Modern Russian Enamel as a Phenomenon of Easel-Decorative Arts
Authors: Steklova Irina Alekseevna , Polyakova Tamara Alexandrovna
Published: January 2023

The research aims to determine approaches to the identification of Russian enamel, to highlight the development trends that have ensured its international success. It can be argued that achieving the aim will contribute to both specification and generalisation of the picture of modern art, which is under the stress of global reformatting. The scientific novelty of the article is represented, firstly, by legitimising easel-decorative arts as an autonomous type; secondly, by providing insight into the decorative essence of enamel in an ambivalent strive to preserve the ancient language and to foster stylistic innovation. As a result of the research, the understanding of this phenomenon is traced to the characteristic features of easel-decorative arts, which objectively depend on the aesthetics of materials and manufacturing technologies and are historically loaded with style-forming and meaning-making functions.

Lightweight sandwich structural components have been widely used in different industries as highly effective energy absorbers. This research aims to provide a comparative study on the role of the composite corrugated sheet as a core in sandwich panels under low velocity impact loading. To reach this goal, the crashworthiness characteristics of three sandwich panels with different corrugated cores, which consist of identical mass and mechanical properties, are evaluated under vertical and transverse loading. The finite element computation is done using LS-DYNA under planar loading conditions. To validate the numerical process, first, the dynamic compression behavior of the square corrugated core sandwich panel made of aluminum alloys in comparison to existing experimental data is analyzed and the appropriate compliance has been observed. Then the effect of composite material and core shape on the crashworthy behavior of sandwich panels is explored. The research results reveal that the material type and geometric configuration of corrugated core have a considerable effect on the mean crushing load and the energy absorption of sandwich panels. It is found that the triangular configuration has a higher capability in load carrying and energy absorption than the square and/or the sinusoidal configuration. The failure modes of the crushed corrugated sandwich panels also significantly influenced by the type of corrugation cores. The present results supply valuable information on low velocity impact response that can be helpful for increasing crashworthy performance and development of such lightweight structures.

A Mechatronics System based on Feature Selection and AI for IoT Intrusion Detection Applications
Authors:   Northern Technical University, Sharif Montassar Aidi
Published: January 2023

In today's rapid development of the Internet, people's daily lives have become easier, but on the other hand, people's privacy is also faced with potential threats if necessary,security measures are not taken. To detect or stop cyberattacks in this area, network intrusion detection systems (IDS) can be equipped with machine learning algorithms to improve accuracy and speed. Recent research on intrusion and anomaly detection has shown that machine learning (ML) algorithms are widely used to detect maliciousweb traffic, using neural networks to learn models to visualize the sequence of connections between computers on a network. By analyzing and selecting the correct features, dense attacks can be detected more accurately, ultimately reducing misclassification rates and improving accuracy. In this study, we propose a Teacher-Student Feature Selection (TSFS) method that first uses the Isomap method to extract and select features in low dimensions and the best display, and then performs classification. The artificial neural MLP-Net for classification is used to minimize diagnostic errors. Although the teacher-student scheme is not new, to our knowledge, this is the first time this scheme has been used to select features in an intruder alert system. The proposed method can be used to select monitored and unmonitored features. The method is evaluated on different datasets and compared with the state-of-the-art feature selection methods available. The results show that the method performs better in classification, clustering, and error detection. Furthermore, experimental evaluations show that the method is less sensitive to parameter selection.

The defects are assessed using multiple diagnostic tools. This review contrasts the seven forms of testing devices, including the Autism Diagnostic Observation Schedule (ADOS), Autism Diagnostic Interview-Revised (ADI-R), Childhood Autism Rating Scale (CARS), Gillian Autism Rating Scale (GARS), Diagnostic Interview for Social and Communication Disorder (DISCO), Developmental, Dimensional & Diagnostic Interview (3DI), and Diagnostic and Statistical Manual of Mental Disorder (DSM). The advantages and limitations of each tool are discussed in detail.

The effect of connected structureonSMK Bukit Tinggibuildingwas investigatedbased ontheirdynamic behaviour. The structure was constructed with four main buildings are interconnected. Ambient vibration testing (AVT) was used to predict the dynamic response and characteristics by using triaxial 1Hz seismometer and CityShark data logger. The AVT signals were analysed using GEOPSY software for Fourier Amplitude Spectral(FAS). All predominant frequencies (fo) and mode shapes were identified and verified with previous research finding using similar testing approach on the same building, but with different instrument of accelerometer sensorand ARTeMIS software processing tool. Five modes of fo were found from the FAS curves from this research, but only four fo were obtained from ARTeMIS analysis. The highest deviation percentage was indicated at the 5thmode of building frequency at 9.5 %, but 0 to 2.5% to the rest frequencies mode (1st to 4th frequencies mode). Ununiformed buildings response behaviour was believed to contribute, and initiate active progressive shear cracking on the slab panels, columns, beam and at the reentrant corners between laboratory and academic buildingsof Building C. It worst when the buildings were struck by several earthquakes’ series. The unsynchronised oscillation between adjacent buildings to Building C had induced couple lateral and torsional deformations. Thestructural and non-structural damages mostly concentrated at the reentrant corners and mid-span of the building, which identical to the location of maximum deflection amplitudes. In conclusion, strict attention must be emphasized on the fo and mode shapes based on their dynamic response and characteristics analyses, which could be altered by the presence of connected structures.

Karadut çeliklerinin kök oluşumunu teşvik etmek amacıyla genellikle IBA gibi büyüme düzenleyiciler kullanılmaktadır. Ancak, günümüzde sürdürülebilir tarım uygulamaları kapsamında, bitkisel üretim sürecinde sentetik kimyasallara alternatif yeni materyallerin ve yöntemlerin araştırma çalışmaları giderek hız kazanmaktadır. Bu tür alternatif uygulamaların başında ise, günümüzde kullanımı gittikçe yaygınlaşan rizobakteriler (PGPR) yer almaktadır. Bu çalışmada da büyüme düzenleyicilerine alternatif olabilecek iki farklı bakteri izolatının (Bacillus cereus (ZE-7) ve Pseudomonas putida (ZE-12) karadut odun çeliklerinin köklenmesi üzerine etkisi araştırılmıştır. Bu amaçla, aralık ayı sonunda Tokat Gaziosmanpaşa Üniversitesi Araştırma ve Uygulama Merkezine ait karadut yetiştiriciliği yapılan seradan temin edilen odun çeliklerine bakteri izolatları tek başına ve 6000 ppm oksin (Indole-3-butyric acid-IBA) ile birlikte uygulanmıştır. Çelikler 10 saniye IBA çözeltisinde ardından 30 dakika bakteri süspansiyonlarında bekletildikten sonra sisleme ve alttan ısıtma sistemi olan köklendirme masasına, tamamı perlit olan ortama dikilmiştir. 90 gün köklenme ortamında kalan çeliklerde kök sayısı (adet/çelik), kök uzunluğu (cm), kök çapı (mm), çürüme oranı, köklenme oranı (%) ve kallüslenme oranı (%) parametreleri incelenmiştir. En yüksek köklenme oranı, 6000 ppm IBA + 0.3 Abs bakteri uygulaması ve 6000 ppm IBA + 1.2 Abs bakteri uygulamasından (%71.11) elde edilmiştir. Kontrole kıyasla köklenme oranı bakterinin kombinesi ile %28 oranında artmıştır. Bakteri uygulamaları genel olarak, kök sayısı, çürüme oranı, köklenme oranı ve kallüslenme oranına olumlu etkilerde bulunurken, kök uzunluğu ve kök çapı parametrelerinde ise artı bir etkisi olmamıştır. Sonuç olarak karadut çeliklerinde standart IBA konsantrasyonu olarak 6000 ppm uygulanmakta ancak bu yeterli gelmemektedir. Elde edilen sonuçlarla bu konsantrasyona ek olarak 0.3 Abs konsantrasyonunda bakteri uygulaması yapılarak standart uygulamaya kıyasla %28 artış sağlanabileceği sonuçlarda yer almaktadır. Ayrıca bakteri uygulamasının sürdürülebilir, kolay hazırlanabilir ve uygulanabilir olması gibi avantajları sayesinde ileride yapılması planlanan köklendirme çalışmalarında önerilmektedir.

Araştırmada Samsun ilinde yetiştirilen salep üretiminin mevcut durumu, pazarlama kanalları ve tüketicilerin salep tüketim durumlarını ortaya koymak amaçlanmıştır. Bu amaçla araştırmada, 52 salep yetiştiricisi, 300 salep tüketicisi ile yapılan görüşmelerden alınan 2021 yılı verileri kullanılmıştır. İncelenen işletmelerde ortalama salep verimi 377 kg/da’dır. Bir kilogram salebin maliyeti 59,07 TL/kg olarak hesaplanmıştır. İncelenen işletmelerin dekara brüt karı 28050,65 TL ve net karı 13624,22 TL’dir. Salep yetiştiren tarım işletmeleri salep yetiştirmek üzere yaptıkları 1 TL masrafa karşılık 1,61 TL kar elde etmektedirler. Endemik bir bitki olan salep orkidelerinin doğadan toplanması ile elde edilecek kısa süreli kazançlara karşı sürdürülebilir kazanç sağlayacak salep tarımının getirisi teşvik edicidir. Makro düzeyde salep yetiştirme koşullarının her bir bölgeye özgü olması ve ihtiyaç olan tohumluğun sağlanması için kurumsal çalışmaların yapılması gerekmektedir. Tüketici araştırmasının sonuçlarına göre bireylerin %52’sinin salep tükettiği tespit edilmiştir. Tüketicilerin %53’ü salebi toz, %42’si hazır içecek ve %5’i kurutulmuş halde almaktadır. Satın alınan salebin %98’si içecek, %2’si pasta yapımında kullanılmaktadır. Tüketiciler yıllık ortalama 1150 ml hazır salep içmektedirler. Salebin piyasada uzun vadede tutunmasını sağlamak için tüketicilerin profillerini dikkate almak, kullanım alanları ve şifalı bir bitki olduğu konusunda bilgilendirmek ve reklam çalışmalarına önem vermek gerekmektedir.

Tarımsal desteklemelerin etkinliğinin değerlendirilmesinde üreticilerin memnuniyeti önem arz etmektedir. Bu çalışmada üreticilerin kaba yem ihtiyacını karşılamada önemli bir yer tutan yem bitkisi desteklerinden memnuniyet durumu etkileyen faktörlerin belirlenmesi amaçlanmıştır. Araştırmanın ana materyalini 2021 yılında Tokat ili Merkez ilçede yem bitkisi üretimi yapan 80 üreticiden yüz yüze anket yoluyla elde edilen veriler oluşturmaktadır. Elde edilen bulgulara göre desteklerden memnun olan üreticilerin oranı %56.25 olarak belirlenirken, %75.00’nin ise destekleme miktarını yeterli görmediği tespit edilmiştir. Bölgede yem bitkisi üretimi yapma amacı ağırlıklı olarak hayvan yetiştiriciliğinde kaba yem ihtiyacını karşılamaya yöneliktir. Bu nedenle üreticilerin büyük çoğunluğunun desteklemelere bağlı olmaksızın üretim yaptığı gözlenmiştir. Buna karşın yeter destek sağlanması durumunda yem bitkisi üretimini arttıracakları görüşünün hakim olduğu söylenebilir. Üreticilerin memnuniyet düzeyini etkileyen faktörlerin belirlenmesinde binary logit modelden yararlanılmıştır. Model sonuçlarına göre üreticilerin desteklemelerden memnun olma olasılığının işletmelerde ekilebilir arazi miktarı artışına bağlı olarak yükseldiği belirlenmiştir. Buna karşın işletme ölçeği büyüdükçe ve büyükbaş hayvan varlığı artıkça üreticilerin memnuniyet düzeyinin azaldığı saptanmıştır. Bunun yanında yem bitkileri desteklerine bağlı olarak üretim yapanlar ile yonca ve fiğ ekimi yapanlarda da memnuniyet düzeyinde azalmalar olduğu sonucuna varılmıştır. Üreticilerin yem bitkisi tarımında kalması ve üretiminde sürdürülebilirliğin sağlanması için desteklemelerde iyileştirme ve geliştirmelere ihtiyaç duyulmaktadır. Bu bağlamda son üç yılda stabil kalan alan bazlı destek miktarlarının maliyetler dikkate alınarak düzenli olarak arttırılmasının, nadas yılı ve ekim nöbetinde yem bitkisi ekimine teşvik edici destek kalemlerinin geliştirilmesinin yem bitkisi üretimini arttırmada etkili olabileceği düşünülmektedir.
