CANDUNGA, DE BRUNO DE MENEZES: UM ROMANCE UTÓPICO E UNIVERSAL NA AMAZÔNIA PARAENSE
Authors: Sousa Willian Ferreira de
Published: September 2024

O presente trabalho faz algumas reflexões sobre o romance Candunga (1954), de Bruno de Menezes (1893-1963), escritor negro, pobre e nascido na periferia de Belém (PA), que usou a literatura, o cooperativismo e o sindicalismo como forma de resistência e luta em prol de uma sociedade justa e igualitária. O livro resguarda as principais características da segunda geração modernista, como as temáticas sociais, dialogando com outras obras desse período, mas o autor paraense e sua produção não obtiveram o destaque necessário pelo cânone. Este artigo visa demonstrar a importância da narrativa e de seu autor, evidenciando-os com características universais, cuja classificação perpassa o regionalismo. As reflexões aqui propostas trilham pela natureza utópica do romance de Menezes que se destaca pelo teor libertário e revolucionário, bem como os conceitos de sedenarrativa e aquonarrativa que emergem do texto.  Para essa discussão, alguns autores foram evocados: Bosi (1994); Cândido (2006); Jobim (2020; 2021); Eagleton (1976); Leão e Campos (2021); Lukács (2000); Nunes (2001; 2004) entre outros. Enfim, este trabalho tem como principal base de análise a metodologia qualitativa e envolve pesquisas bibliográficas, cujas informações apontam a importância do romance em tela e de seu autor para o cenário literário amazônico e brasileiro.

Published: September 2024

This study aimed to examine the water quality of and presence of genes linked to cyanobacterial toxins in 17 reservoirs in Gyeonggi Province, South Korea. The levels of TN, TP, and chlorophyll-a indicated nutrient conditions ranging from eutrophic to hypereutrophic, consistent with international standards. Most reservoirs were found to be vulnerable to algal blooms beyond the eutrophication stage. Chlorophyll-a correlated positively with TP and TOC but negatively with TN in most reservoirs. The mcyA gene for microcystin was detected in 14 reservoirs, with a 64.9% detection rate. The toxin was detected in 47.2% of these cases, with increased concentrations in summer. The dominant microcystin variants were MC-LR>MC-RR>MC-YR. The anaC gene for anatoxin-a was detected in 11 reservoirs at an 18.9% rate, with a toxin detection rate of 9.5%. The aoaB gene for cylindrospermopsin was detected in six reservoirs at a 12.6% rate, although the toxin itself was not detected. This study emphasizes the ongoing presence of cyanobacterial toxin genes and their toxins in Gyeonggi Province reservoirs. The potentially increasing adverse impact of these toxins, because of climate change, needs to be addressed via continuous monitoring and management.

Published: September 2024

This study examines the emission characteristics of nonylphenol (NP) and octylphenol (OP) in the discharged water of Northern Gyeonggi Province, South Korea, where the textile industry predominates. We evaluated 104 individual wastewater discharge facilities, six public wastewater treatment plants (WWTPs), and the Shincheon River. Our findings reveal that NP and OP concentrations were notably high in the textile industry, with median levels of 0.53 µg/L and 0.43 µg/L, respectively, in individual wastewater discharge facilities. Furthermore, monitoring NP and OP levels in the influent and effluent of WWTPs and river water demonstrated that WWTP effluent has a remarkable impact on NP and OP concentrations in the river. The removal rates of NP and OP in WWTPs averaged 69.6% and 41.8%, respectively, and these rates tended to increase with higher temperatures and influent concentrations. The average concentrations in the Shincheon River were 0.31 µg/L for NP and 0.45 µg/L for OP, slightly exceeding EU standards. It is essential to closely monitor NP and OP levels to protect aquatic ecosystems.

Published: September 2024

This study analyzes the indoor air quality inspections of newly constructed apartments by the Busan Institute of Health and Environment for the last three years (2021-2023). Of the 41 inspections, 33 exceeded the recommended standard, and the average excess rate was 80.5%. When classified by measuring households, 148 out of 332 exceeded the standards, whereas, the average excess rate by household was 44.6%. Benzene was exceeded in two out of the 332 households; therefore, the excess rate was only 0.6%. However, the relative standard deviation was the largest, showing as the highest item in the scattergram. The average concentration of toluene was 1,006.0 µg/m3, which was 100.6% of the recommended standard and was exceeded by 138 households; hence, the excess rate was 41.6%. All six items(Formaldehyde, Benzene, Toluene, Ethylbenzene, Xylene, Styrene) reached the highest concentration in spring or summer when the indoor temperature increased. The average concentration of toluene in July was 1,922 µg/m3, close to 1.9 times the recommended standard; toluene is considered an item of particular concern in summer. In the correlation analysis with indoor temperature, the formaldehyde coefficient of determination was 0.4855, regarded as somewhat significant; it was difficult to confirm the correlation with temperature for the other five items, including benzene. In correlation with relative humidity, formaldehyde showed the same tendency as indoor temperature, with a coefficient of determination of 0.4404, which is believed to be due to its small molecular weight and high solubility. Due to the chimney effect, high concentrations of volatile organic compounds could be confirmed at low atmospheric pressure in the upper floors, and this trend was most evident for formaldehyde. For most items(Formaldehyde, Benzene, Toluene, Ethylbenzene, Styrene), a negative correlation was confirmed in which the emission amount decreased as the number of households increased. For large apartment houses, it is believed that it is due to sufficient bake-out and flush-out according to the adequate construction period and the use of eco-friendly and high-end building materials. Small apartments are classified together with many small houses. The emission concentration of small houses is relatively high because the proportion of the surface area where pollutants are released is high.

A chikungunya, uma arbovirose transmitida por mosquitos do gênero Aedes, tem se consolidado como uma significativa ameaça global à saúde pública, em especial nas regiões tropicais e subtropicais. O quadro clínico da doença é marcado por uma fase aguda de febre intensa e dores articulares debilitantes, frequentemente evoluindo para uma condição crônica caracterizada por artralgia prolongada e outras manifestações inflamatórias. A ausência de terapias antivirais específicas e de vacinas eficazes torna o manejo da chikungunya majoritariamente sintomático, o que sublinha a necessidade urgente de novas abordagens terapêuticas. Diversos compostos antivirais têm sido investigados em ensaios pré-clínicos, porém os resultados clínicos ainda são insuficientes para sua implementação prática. Da mesma forma, o desenvolvimento de vacinas enfrenta desafios, como a indução de imunidade duradoura e a segurança em populações de risco. Além disso, a eficácia de intervenções profiláticas, como o controle de vetores, apresenta limitações, especialmente em áreas endêmicas de difícil acesso. Este artigo analisa criticamente as estratégias terapêuticas e preventivas atuais contra a chikungunya, discutindo os avanços e os obstáculos no desenvolvimento de antivirais e vacinas. O trabalho também explora a importância de uma abordagem integrada que combine medidas de vigilância epidemiológica, controle vetorial aprimorado e educação em saúde para mitigar a propagação da doença. Conclui-se que, embora existam promissoras inovações em andamento, a superação da chikungunya exige uma resposta coordenada entre a comunidade científica, os governos e a indústria farmacêutica, com vistas a promover intervenções eficazes e sustentáveis a longo prazo.

“PAPER” CRISIS IN SIBERIA DURING THE FIRST WORLD WAR AND CIVIL WARS (BASED ON MATERIALS OF THE CITY OF MINUSINSK, YENISEI PROVINCE)
Authors: Dolidovich Olesya , Alekseev Oleg , Revyakina Darya
Published: September 2024

The paper examines the causes and development of the "paper" crisis in Siberia in 1914-1922. The paper supply to the region before the beginning of the 20th century is analyzed, the economic processes that led to the growth of its cost and deficit during the First World War are studied, and the measures of the Kolchak and Soviet governments to solve the problem during the Civil War are identified. It is shown that serious territorial disproportions in industrial production developed even in the pre-war period, paper enterprises were concentrated in the western regions. Of great importance was the fact that the country imported up to 30% of the required volume of paper. In Siberia, despite the presence of large reserves of raw materials, paper was not produced. Siberian entrepreneurs could not withstand competition with manufacturers in European Russia. Paper was imported to the region, which led to significant transportation costs. With the outbreak of military action, paper production was significantly reduced due to a number of reasons, such as the loss of factories in frontline areas, a shortage of raw materials, fuel, and labor, the disruption of trade, and widespread speculation. In Siberia, the crisis was felt particularly acutely due to the disruption of regular transportation. Already during this period, strict paper savings began in the offices of central and local government bodies. During the Civil War, the shortage increased significantly. Military action on the territory of the country did not allow the full use of the capacity of existing enterprises or the expansion of paper production, so the warring parties could only reduce its consumption. The recovery of the industry began during the NEP years, but the pre-war level of production was never achieved. Dependence on imports remained.
ANALYSIS OF ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE OF A COMMERCIAL ORGANIZATION
Authors: Kochelorova Galina
Published: September 2024

The result of commercial activity of any organization is determined not only by its efficiency, but also by the financial and economic activity of its partners. As a result of non-compliance with the terms of contracts between economic entities, various situations arise related to the untimely receipt of funds, failure to fulfill obligations, which subsequently complicates the processes of purchasing material assets necessary for the implementation of production activities. Failure to fulfill obligations by both debtors and creditors leads to the emergence of financial debt, a decrease in payment capabilities and the level of profitability. The presence of accounts receivable leads to insufficient working capital, which negatively affects all processes occurring in the organization, up to the delay in cash payments due to employees of the organization. However, this is a normal process arising as a result of settlement transactions with counterparties. Accounts payable arise due to untimely fulfillment of obligations to suppliers or contractors, and have a significant impact on the business reputation of an economic entity. Untimely repayment of accounts receivable leads to the risk of overdue debt and non-receipt of funds for shipped material assets, as well as services rendered or work performed. The presence of overdue accounts payable leads to deterioration of business reputation and possible legal problems. A well-organized system of accounting and analysis in an organization allows finding the optimal ratio between accounts payable and receivable, ensuring more efficient operation of the entire economic entity in order to prevent a decrease in financial stability. A special role is given to internal control, which is designed to ensure compliance with the law in settlements with business partners.
ON SOME WAYS TO ADDRESS THE ISSUE DETERMINING REROUTING CARGO FLOWS COSTS IN CAPACITY CONSTRAINTS CONDITIONS
Authors: Bykadorov Sergey , Lyazzat Taskenovna
Published: September 2024

The paper examines the existing and newly designed transport routes of the Eurasian space, passing through the territories of Russia, Kazakhstan and Uzbekistan. Due to new geopolitical conditions, both transport and economic ties and cargo flows throughout the Eurasian space have changed significantly. New logistics routes require updating economic standards for calculating operating costs, cost price, as well as the tariff regulation system on existing and designed transport sections. New approaches are needed to improve interstate relations and international interaction between transport organizations of neighboring states. The transport corridors of Russia, Kazakhstan and Uzbekistan are closely linked both with each other and with the transport systems of a number of foreign countries - China, Iran, India. Therefore, it is necessary, on the one hand, to strengthen cooperation between transport organizations of these countries, and on the other hand, to resolve problems related to technological and transport-logistics interaction with these states. Thus, if the railways of the former USSR countries have very similar transportation technology and development history, then other countries are unique in this regard. It is also necessary to take into account the different approaches to the issues of transport industry management, fragmentation of the transport business, as well as issues of ownership of rolling stock and transport infrastructure. The authors emphasize the relevance of a new approach to calculating railway tariffs based on sectional cost. They provide existing and proposed dependencies for these purposes.

The need to improve the quality and reliability of electricity transmission based on the improvement of production technologies determines the relevance of solving the problem of ensuring sustainable innovative development based on the use of special tools for strategic planning of innovative development of enterprises engaged in the transmission and distribution of electricity (hereinafter referred to as power grid enterprises). At the first stage of the study, the features of innovative development of production activities of enterprises engaged in the transmission and distribution of electricity were determined based on the identification and systematization of factors. At the second stage, the methodological principles and tools for developing a strategy for innovative development of production activities of a power grid enterprise were studied. Based on the obtained results of the study of the features of innovative development of enterprises engaged in the transmission and distribution of electricity and the methodological aspects of developing a strategy for innovative development of the enterprise's production activities, tools were proposed for developing a strategy for innovative development of the production activities of the branch of PJSC Rosseti Siberia – Krasnoyarskenergo. Such tools include a system of interrelated production indicators for the formation of a strategic production development program, which allows for an assessment of the level of innovative development of power grid enterprises; an optimization model for the formation of a strategic innovative production development program, taking into account the costs of implementing innovative projects and the risks arising from the implementation and trial operation of innovative production development projects. The practical use of the proposed tools for strategic planning of a power grid enterprise – a system of production indicators of innovative development and an optimization model – is aimed at improving the quality of corporate management based on the analysis, planning and monitoring of production indicators and the formation of an effective portfolio of innovative projects that ensures the improvement of production indicators while limiting the innovative risks of strategic development of production of a power grid enterprise.
"SIBERIAN FEUDAL LORDS" KRASNOYARSK STATE PEDAGOGICAL UNIVERSITY: ON THE HISTORY OF THE SCHOOL OF SPECIALISTS IN THE 17TH - EARLY 19TH CENTURIES
Authors: Pavlova Irina , Pavlov Pavel
Published: September 2024

The paper is devoted to the analysis of the scientific activities of scholars from the Krasnoyarsk State Pedagogical University (Institute), specialists in the history of Siberia in the 17th – early 19th centuries. Based on the analysis of archival materials, published works of researchers, and interviews, the research path of scientists and teachers is shown. Since the late 1950s, P.N. Pavlov was the first in Russian science to begin an in-depth study of the fur trade and industrial colonization of Siberia. Pavlov's research is devoted to the 17th century, the heyday of the Russian fur trade and fur commerce. He studied materials on the Mangazeya, Yenisei, Ilimsk and Yakutsk districts, which constituted the main fur trade area; he showed the quantity and composition of the furs obtained, their prices, found out the origin of industrial hunters and other aspects of the fur trade. G.F. Bykonya began researching the topic of Russian settlement in the Prienisei region. The focus of his scientific interest was feudal relations in Siberia. He studied in detail the process of formation of the administrative and economic layer of Siberians, the social and class composition of serving people in Eastern Siberia. Bykonya is an active popularizer of historical science, preparing important sources on the history of Siberia for publication. V.V. Bulankov studied the history of Yeniseisk at the stage of "late feudalism". He determined the class composition and occupation of the inhabitants of the first capital of the Prienisei region. He showed that the main occupations of the Yeniseians were crafts (metallurgy, metalworking, stone construction, etc.) and trade. All three researchers - teachers of the Pedagogical Institute, methodologists, educators of history teachers - prepared textbooks, worked in the field of protection of historical and cultural monuments. The authors of the paper came to the conclusion that, with various interpretations of the concept of "feudalism" from the point of view of today's science, researchers have created fundamental, highly qualified works on the history of socio-economic relations in Siberia based on archival materials.
Wide-angle broadband metamaterial absorber with carbon black-carbonyl iron/polylactic acid composites fabricated by fused filament fabrication
Authors: Wang Fei , Zhou Qianfeng , Liu Hongsheng , Fang Pengfei , Jiang Kaiyong , Li Peifeng
Published: September 2024

A complex composite structure comprising periodic stepped square hole (SSH) units was designed to achieve wide-angle broadband microwave absorption. The SSH structure serves as a metamaterial absorber and was fabricated with carbon black, carbonyl iron powder, and polylactic acid composite by fused filament fabrication 3D printing. Only 50 wt% addition of loss material was required in the composite filament. Electromagnetic simulation was developed to investigate the effect of geometric parameters of the SSH structure on the microwave absorption performance, using the measured complex permittivity and permeability of the composite as the input. The geometric parameters were optimized for absorption reflection loss and bandwidth in the electromagnetic simulation. The simulation revealed that the optimal SSH structure with a height of 18 mm can achieve a –10 dB absorption bandwidth of 14.032 GHz in the frequency range of 2 – 18 GHz with a reflectivity peak (−45.74 dB) at 15.056 GHz. The optimal structure can sustain strong absorption and broadband performance with incident angles of 0 – 50° for both transverse electric polarization and transverse magnetic polarization. The simulation results were verified by reflectivity experiments on the SSH structure with optimal geometric parameters. This work provides an effective and promising approach for the practical application of strong broadband and wide-angle microwave absorption.
SCULTURE DEL COMPLESSO MONUMENTALE DI VIA DELLE TERME A PORTO TORRES - TURRIS LIBISONIS (SARDEGNA, ITALIA)
Authors: Teatini Alessandro
Published: September 2024

Il monumentale complesso di via delle Terme è stato messo in luce tra il 2006 e il 2010 a Porto Torres, antica Turris Libisonis, ma successivamente solo brevi saggi sono stati pubblicati al riguardo da parte degli scopritori. Si affronta qui per la prima volta uno studio frontale delle notevoli sculture in marmo rinvenute, per inserirle finalmente nel contesto della ricerca sulle rispettive classi di materiali. Ad una sintesi sulle strutture messe in luce segue inizialmente lo studio della decorazione architettonica, grazie al quale è possibile inquadrare cronologicamente in maniera abbastanza precisa la costruzione del complesso. Si prosegue poi con l’analisi delle statue: due torsi loricati e una figura di Ercole. I pezzi vengono puntualmente riferiti alle rispettive seriazioni tipologiche e, con motivazioni dettagliate, si propone sia l’attribuzione ad una specifica iconografia nel caso della statua di Ercole, sia il riconoscimento di specifici principes nel caso dei due loricati. Vengono allo scopo ricollegati fra loro nuovi e vecchi ritrovamenti, arrivando così a definire la probabile presenza di una galleria di statue imperiali, l’unica della provincia romana della Sardegna ad essere stata incrementata con ulteriori dediche nel lungo periodo, almeno dal periodo claudio all’età antonina avanzata, forse in stretto rapporto con un monumento del culto imperiale.

Genel anlamda mantığa dayalı soyut bir bilim dalı olarak görülen matematiğin birçok insanda sevmek ya da nefret etmek gibi yoğun duygusallık uyandırdığı ifade edilmektedir. Duygusal yaklaşımların temelinde matematiğe karşı duyulan kaygının yer aldığı vurgulanmış, bu durum da matematik kaygı düzeyinin incelenmesinin önemini ortaya koymuştur. Araştırma ile İstanbul ilinde bulunan ortaokul öğrencilerin matematik kaygı düzeylerinin belirlenmesi ve bu düzeyin cinsiyet, devam ettikleri okul türü, bilim ve sanat merkezlerinde kayıtlı olup olmama durumları ve kendilerini en başarılı hissettikleri alanlara göre farklılık gösterip göstermediği araştırılmıştır. Araştırmanın örneklemini İstanbul ili Ataşehir ilçesinde eğitim gören 160 öğrenci oluşturmaktadır. Araştırmada yöntem olarak nicel araştırma yöntemlerinden biri olan tarama modelinden faydalanılmıştır. Araştırmada veri toplama aracı olarak Ertkin, Dönmez ve Özel (2006) tarafından geliştirilen “Matematik Kaygı Ölçeği” ve kişisel bilgi formu kullanılmıştır. Elde edilen veriler “Matematik Sınavı ve Değerlendirilme Kaygısı”, “Matematik Dersine İlişkin Kaygı”, “Günlük Yaşamda Matematik Kaygısı” ve “Matematik Konusunda Kendine Güven” alt boyutlarında değerlendirilmiştir. “Matematik Kaygı Ölçeği”nin tüm boyutlarında ve ölçek genelinde kız öğrencilerden yana; matematik sınavı ve değerlendirilme kaygısı, günlük yaşamda matematik kaygısı alt boyutlarında ve ölçek genelinde devlet okulunda eğitim gören öğrencilerden yana; matematik sınavı ve değerlendirilme kaygısı, günlük yaşamda matematik kaygısı ve matematik konusunda kendine güven alt boyutlarında bilim ve sanat merkezine kayıtlı olmayan öğrencilerden yana; matematik konusunda kendine güven alt boyutunda kendisini sayısal alanda yetenekli bulan öğrenciler ile kendisini sözel alanda ve spor alanında yetenekli bulan öğrenciler arasında kendisini sayısal alanda yetenekli bulan öğrencilerden yana anlamlı farklılık bulunmuş olup kayıtlı olunan sınıf düzeyinde anlamlı farklılık bulunmamıştır. Elde edilen sonuçların matematik öğretimi sürecinde eğitimciler tarafından değerlendirilerek kaygı düzeyinin azaltılması konusunda yapılacak çalışmalarda kullanılabileceği düşünülmektedir. Benzer araştırmalar nitel araştırma yöntemleri kullanılarak gerçekleştirilebilir ve matematik kaygısı nedenleri derinlemesine incelenebilir..
Globally Linearizing Control for a Magnetic Microrobot Navigating Within a Blood Vessel

Published: September 2024

In this paper, the globally linearizing control scheme is employed to guide an endovascular magnetic microrobot navigating within a blood vessel with the objective of reaching a desired target following a trajectory generated via a joystick device. First, we derive the 1D nonlinear dynamical model for the magnetic microrobot. Subsequently, a stabilizing state feedback is designed based on the relative degree from geometric control, resulting in a closed-loop linear system. To ensure the tracking of a time-varying trajectory and reject disturbances, an external proportional-integral controller with a bias is used to define the external variable of the resulting linear system. The performance of the GLC is evaluated via numerical simulations. The obtained results demonstrate the output tracking and disturbance rejection capabilities of the GLC scheme.

Published: September 2024

Tyrimo tikslas. Įvertinti muzikos terapijos (MT) poveikį neišnešiotų naujagimių (NN) motinų gerovei –patiriamo nerimo lygiui ir motinos bei naujagimio ryšiui. Metodai. Tyrimas atliktas Vilniaus universiteto ligoninės Santaros klinikų Neonatologijos centro Naujagimių skyriuje. Motinoms, slaugančioms savo NN (vidutinis gestacinis amžius – 29 sav., gimimo svoris – 1 369 g), „kengūravimo“ metu taikyta MT. Motinos skatinamos atsipalaiduoti ir įsitraukti į niūniavimo ir dainavimo naujagimiui procesą. Atlikta MT taikymo kiekybinė analizė, naudojant Būsenos ir bruožo nerimo klausimyną, Motinos ir naujagimio ryšio skalę. Pasirinkta kvazieksperimentinė tyrimo strategija, lyginant duomenis prieš intervenciją ir po jos. Rezultatai. Tyrime dalyvavo 19 motinų. Atliktos 92 MT sesijos. Dažniausiai tiriamosios dalyvavo keturiose (42 proc.) MT sesijose. Stebėta teigiama MT poveikio tendencija, nors statistiškai reikšmingas MT poveikis motinų nerimui, motinos ir naujagimio ryšiui nenustatytas. Išvados. Muzikos terapijos intervencijos, taikomos neišnešiotų naujagimių motinoms „kengūravimo“ metu, teigiamai veikia motinų gerovę – nustatyta nerimo mažėjimo bei geresnio motinos ir naujagimio ryšio formavimosi tendencija.

Tyrimo tikslas. Išanalizuoti mokslinės literatūros publikacijas apie preeklampsijos rizikos vertinimą, ankstyvąją diagnostiką, prevencines priemones. Tyrimo metodai. Literatūros apžvalgos straipsnių paieška vykdyta „Pubmed“ duomenų bazėje. Naudoti šie reikšminiai žodžiai: „Biomarkers“, „Maternal factors“, „Prediction“, „Preeclampsia“, „Prevention“ ir jų kombinacijos. Atrinkta ir įtraukta 15 pilno teksto publikacijų anglų kalba, išspausdintų 2014-2024 m. Rezultatai ir išvados. Preeklampsija ir toliau išlieka pavojinga motinai bei vaisiui patologija, kurios efektyviausias gydymo būdas – nėštumo užbaigimas. Labai svarbus yra rizikos grupių identifikavimas ir ankstyva preeklampsijos diagnostika. Pažangiausias šiuo metu naudojamas šios ligos diagnostinis modelis apima ne tik motinos medicininės ir gyvenimo anamnezės aspektus, bet ir keturis reikšmingus biofizinius rodiklius. Preeklampsijos patogenezėje esminį vaidmenį atlieka proangiogeninių ir antiangiogeninių faktorių pusiausvyra. sFlt-1/PIGF tyrimas yra vertingas įrankis preeklampsijos diagnostikos ir eigos prognozavimo procesuose, taip pat leidžiantis taikyti efektyvias prevencines priemones, tokias kaip profilaktiką mažomis aspirino dozėmis. sFLT-1 ir PIGF santykio tyrimo Lietuvoje patvirtinimas yra svarbus žingsnis siekiant geresnės nėščiųjų priežiūros ir sėkmingesnių nėštumo baigčių.
