Published: February 2024

Background: The coronavirus disease 2019 (COVID-19) poses a threat to the global economy and public health. Mutations in the spike protein of the virus can impact the functional characteristics and effectiveness of vaccines. Objectives: This study aimed to analyze mutations in three key regions of the spike protein, investigate clinical presentations, and assess protective immune levels in healthcare workers (HCWs) who had received full vaccine doses but were re-infected. Methods: In this cross-sectional study, 49 breakthrough-infected HCWs were included from November 2021 to May 2022. After confirming COVID-19 reinfection, the SARS-CoV-2 genome was extracted using the ROJE extraction kit, and genetic variation analysis was performed through Sanger sequencing. Blood samples were collected with prior consent, and ELISA tests were performed to determine antibody levels. Clinical presentations were recorded, and independent t-tests revealed no significant gender-based differences in the C-terminal point mutation. Results: In this study, 75.5% (37/49) of the included HCWs were female (P-value < 0.05), and 25 were qualified for PCR and gene sequencing. Mutations were observed in 25, 10, and 1 sequence(s) of the C-terminal domain, N-terminal domain, and RBD regions of the S1 gene, respectively. The mutations had no significant correlation with the patient's gender, age, or occupation, but they were significantly more prevalent in those with underlying diseases. 63.3% (31/49) of patients had high or very high IgG levels, and none had undetectable antibody levels at the time of reinfection. Loss of the sense of smell (69.4% - 34/49), sore throat (65.3% - 32/49), headache (59.2% - 29/49), and cough (57.1% - 28/49) were the most prevalent clinical manifestations (P > 0.05) in breakthrough-infected HCWs, aligning with the pattern of symptoms seen in the Omicron wave. However, the loss of the sense of taste showed significant results concerning clinical manifestation (P < 0.05). The examination of mutations revealed the presence of the Omicron variant in the majority of individuals. Point mutations in the C-terminal region did not significantly vary based on age, gender, or vaccine type. No significant difference was observed between vaccine types and clinical symptoms. Conclusions: In conclusion, this study identified spike protein mutations in reinfections among vaccinated healthcare workers. While mutations were prevalent, no significant correlations were found with demographics or vaccine types. Symptoms resembled the Omicron variant, notably with the loss of the sense of taste as a significant marker. Detectable antibody levels post-reinfection suggest that vaccine-induced immunity remains robust. Continuous monitoring of virus variants is crucial for optimizing vaccination strategies in the face of evolving strains.
Role of Transcriptomics in Precision Oncology
Authors: Srivastava Ruby
Published: February 2024

: Transcriptome profiling is one of the most widely used approaches in the field of multiomics research. It plays a crucial role in the prognostic, diagnostic, and predictive treatment of cancer patients. Novel next-generation sequencing (NGS) technologies permit the identification of cancer biomarkers, gene signatures, and their abnormal expression, affecting oncogenic and molecular targets and novel biomarkers for cancer therapies. Multiomics studies have changed the overall understanding of cancer and opened a precise perspective for tumor diagnostics and therapy. The use of these approaches has strengthened our understanding of disease pathophysiology and classifications at the molecular level, including specific interference with drug mechanisms of action. Still, it has limited added value in the clinical setting. The omics data on precision medicine include the application of data from genes, transcripts, and proteins for diagnosis, monitoring of diseases, risk factor determination, counseling, and development of novel therapeutics. Bioinformatics applications have expanded statistics-based analysis toward deriving molecular pathways and process models for characterizing phenotypes and drug action mechanisms. In this review, we will discuss transcriptomics and interference analysis that allows the identification of predictive biomarkers at the molecular level to test drug response and analyze the molecular process interface of disease progression-relevant pathophysiology and mechanism of action to propose predictive biomarkers.

An assessment of relative potential impacts to Cyprus’ shoreline due to oil spills in the Eastern Mediterranean Sea
Authors: Silveira de Souza Nikolas Gomes , Lugon Jr. Jader , Yamasaki Edna N. , Kyriakides Ioannis , Neto Antônio J. Silva
Published: February 2024

An oil spill occurrence is a concerning pervasive situation that can result in significant risk, depending on where it starts, the oil properties, and the environmental conditions. In the region of Cyprus, there is an intense traffic of shipping activities which intensifies the risk of an oil spill due to vessel density and prolongated permanence time. The purpose of this work is to obtain the relative potential impact in Cyprus by performing an assessment based on mathematical simulations to identify the critical places in the Eastern Mediterranean Sea, aiming at increasing the readiness for minimising the impact of an oil spill in sensitive areas, with attention to the atmosphere, hydrosphere, lithosphere, biosphere, and anthroposphere. This work simulated 384 scenarios using Mohid and Opendrift platforms with the same data input. The preliminary results presented significant impact in Cyprus’ western regions, mainly. However, after interpolating with history, sensitivity, distance, and two models, only three specific regions showed a potential relative impact. Though different platforms have been used, there were some equivalences in the predictions. Based on it, a new and more specific mathematical method was proposed to assess the potential relative impact of an oil spill in Cyprus, concluding that even with much more intense oil transport in other areas of the Eastern Mediterranean Sea, the most significant relative risks are in fact, in the areas surrounding Cyprus. In particular, the region in the south, east and west of Cyprus. It must be emphasised that the south of Cyprus is an important region for the economy of the country.

Evaluating Young Consumers’ Perception of Online Shopping Convenience
Authors:   Faculty of Business Studies, Premier University, Chattogram, Bangladesh., Chakraborty Anindita
Published: February 2024

This study aims to investigate how online shopping convenience affects the behavioral intentions of young consumers. More precisely, this paper looks for e-shopping characteristics that could influence consumer decisions to make purchases online. A sample of 220 responses was collected from students with experience in e-shopping from a renowned private university in Chattagram using a non-probability convenience sampling method through a 5-point Likert scale questionnaire. To evaluate the hypotheses, a multiple regression analysis was conducted using the SPSS 26 software. According to the study, online shopping convenience has a positive correlation with behavioral intentions. This includes transaction and post-purchase convenience, among other dimensions. The study found no significant relationship between ease of access, search, and evaluation convenience with behavioral intention. The findings of the study provide some practical implications on the dimensions of e-retailing that inhibit young consumers from purchasing online and also help online businesses find out the major barriers as well as the ways of overcoming these barriers to provide a highly convenient service in e-shopping to consumers that will build a long-term customer base.

The objective of this study was to present a methodological tool for the phenotypic evaluation in progeny tests of Guazuma crinita in producer plots of the Aguaytía river basin, Ucayali, Peru, which allows field technicians to standardize the morphological evaluation criteria of trees in forest plantations. Therefore, the phenotypic traits were evaluated for plant height (m), diameter at the height of the base (cm), number of branches, number of rings, stem form, branch orientation, presence and quantity of leaves. The heritability and genetic and phenotypic correlations between traits were also estimated. Therefore, 32 morphological categories were plotted based on the significant correlations (p≤ 0.05) shown between the place of planting, the stem form, the orientation of the branches and the presence of leaves. For the same reason, the progeny showed low morphological patterns, being a low factor of phenotypic variability. It is concluded that the correlations between the biometric and morphological traits evaluated, allowed to validate the phenotypic evaluation procedures of Guazuma crinita progeny tests at 36 months of age.

Published: February 2024

O objetivo da pesquisa é apresentar um relato de atividades de ensino de Geomorfologia que envolve maquetes, anáglifos, mapas de hipsometria e de rede de drenagem. As atividades relatadas neste artigo são parte de um projeto maior, que ocupa-se da elaboração de atlas geoambientais de municípios do Centro-Oeste do Rio Grande do Sul e da criação de materiais didáticos para dar suporte aos professores dessas redes municipais. A atividade foi aplicada em escolas de ensino fundamental de Jari e Nova Esperança do Sul, RS. A maioria dos alunos tinham conhecimentos prévios e conseguiram visualizar os conceitos através das imagens anáglifos e das maquetes. Porém, no que se refere à interpretação de mapas, menos de 25% dos estudantes conseguiram identificar pontos de alta e baixa altitude, assim como a direção de escoamento da água, o que está ligado à carência de noções de alfabetização cartográfica: dificuldades em criar e ler legendas; dificuldades em inserir símbolos no mapa; memorização dos pontos cardeais, já que 17% dos alunos indicou que a água só pode ir para o sul - porção denominada como “para baixo” do mapa. Salienta-se que é importante pensar em um ensino de Geomorfologia voltado para o local, com o uso de estratégias diversificadas e pautadas nas noções de alfabetização e letramento cartográfico.

Published: February 2024

A cidade de Manaus apresenta inúmeros corpos de água chamados igarapés (caminho de canoa – do tupi) e isso se deve à proximidade do lençol freático à superfície, às condições climatológicas e à geomorfologia da região. Sabe-se que a cidade de Manaus passou por um intenso e vertiginoso processo de urbanização, associado a uma grande pressão poluidora sobre os recursos hídricos, não só os corpos de água superficiais, mas também o aquífero. As razões iônicas são formas de se estabelecer similaridades em ambientes geológicos e mostram como podem existir ambientes distintos com geoquímica semelhantes. Contudo, aspectos químicos similares nem sempre caracterizam condições de naturalidade e podem representar influência antropogênica. Diante disso, esse estudo teve por objetivo avaliar as razões iônicas de Mg/Na - Ca/Na, HCO3/Na - Ca/Na e Na/Cl x condutividade elétrica, a partir de um monitoramento destas variáveis, que se estendeu de junho de 2021 a maio de 2022, na Bacia Hidrográfica do Educandos, em Manaus, associando o estudo entre águas superficiais e águas subterrâneas. Os resultados sugeriram que há semelhança entre o aquífero e o igarapé em 2/3 das amostras de água subterrânea o que pode ser um forte indício de uma interação entre aquífero e água superficial, possivelmente, em uma infiltração no sentindo igarapé – aquífero.
Seguindo a construção de fatos e mapeando redes: urnas eletrônicas brasileiras são confiáveis?
Authors: Vinhas Otávio , Prates Camila Dellagnese
Published: February 2024

Este artigo descreve a controvérsia acerca da confiabilidade das urnas eletrônicas brasileiras, no contexto das eleições presidenciais de 2018, utilizando a lente teórica e metodológica da Teoria Ator-Rede (TAR) de Bruno Latour e colaboradores. A delimitação do campo empírico abrange o período compreendido entre o resultado final das eleições presidenciais de 2014 até o final pleito eleitoral de 2018. Acerca disso este trabalho tenciona a relação entre a participação democrática na escolha dos representantes do povo e o uso da urna eletrônica como uma mediadora da escolha pessoal e dos resultados das eleições. Metodologicamente utiliza-se a cartografia das controvérsias (Latour, 2016) para captar as movimentações do enunciado “urnas eletrônicas são confiáveis” em frente a um contexto de disputas acirradas que marcou o cenário eleitoral brasileiro. A rede expõe como opera a dinâmica de disputa entre grupos opostos e também como um enunciado é fortalecido e estabilizado em detrimento de outro. A rede permite problematizar que quando se questiona a funcionalidade da tecnociência é possível, por meio de um contexto de democratização técnica (Callon et al., 2014), expandir as fronteiras o debate entre técnicos e leigos para fortalecer o sistema de voto no Brasil.
Sociedade civil, transnacionalização e projetos políticos na América Latina contemporânea no contexto da disputa por hegemonia
Authors: Silva Sandro Pereira
Published: February 2024

O conceito de sociedade civil vem recebendo nos últimos anos um grande destaque enquanto categoria analítica sobre diversos fenômenos que marcaram as transformações tanto na organização social propriamente dita quanto na geopolítica global. Neste trabalho, a proposta foi analisar as diferentes abordagens sobre sociedade civil e sua importância no processo recente de mudança social e redemocratização nos países latinoamericanos. Buscou-se enfatizar como a democracia, ao mesmo tempo em que permitiu novas reconfigurações na sociedade e suas organizações, também explicitou a disputa por hegemonia presente na diversidade de atores políticos na região. Nesse sentido, o processo de democratização na América Latina, que permitiu uma reativação do associativismo civil e das lutas sociais na região, pode ser examinado em função da mudança de atitudes no comportamento dos atores e movimentos sociais que vão além das relações institucionalizadas entre Estado e sistema político. Em síntese, esse processo pode ser caracterizado por uma disputa por diferentes projetos e concepções em torno da consolidação da democracia e da própria noção de Estado democrático.

Implementasi Wakaf tidak hanya berkembang pada barang-barang tidak bergerak seperti rumah ibadah dan bangunan-bangunan penting lainnya, melainkan sudah merambah pada konsep wakaf uang tunai. Namun dalam implementasinya, wakaf uang mengalami kendala dalam pengembangannya meskipun pemerintah mengeluarkan UU Undang No 41 Tahun 2004 tentang wakaf uang supaya tidak terjadi penyelewengan dalam pengelolaannya. Penulis tertarik mengkaji permasalahan tersebut dikarenakan wakaf benda bergerak (uang) pada masa sekarang ini justru mempunyai nilai kemanfaatan lebih banyak, tidak hanya sekedar sementara atau sekali pakai sudah habis. Seiring perkembangan zaman yang pesat di masa sekarang wakaf  uang pun banyak  dimanfaatkan  nilainya  sehingga  jauh  dari unsur kerusakan.  Hasil peneitian mencermati pendapat dan dasar hukum pendapat Sayyid Sabiq tentang wakaf uang sebagaimana dapat dilihat dari penjelasan sebelumnya, bahwa alasan Sayyid Sabiq tidak mengesahkan wakaf uang dikarenakan banda tersebut cenderung mudah habis ketika dibelikan sesuatu yang ringan, seperti lilin, minyak wangi, sehingga ketika sekali pakai, maka benda tersebut tidak jelas bekasnya. Jika dikelola dengan maksimal sehingga dapat membantu memenuhi kebutuhan hidup masyarakat.

Produktywność czynników wzrostu PKB
Authors: Florczak Waldemar
Published: February 2024

The article quantifies impact of total factor productivity (TFP) on the long term economic growth in Poland in years 1970–2005. The Wharton method was applied to estimate the TFP value (cleaned of short term fluctuations) which, next, was made function of adequate supply factors including social, demographical as well as institutional considerations. A gradation of particular variables explaining effective TFPs equations was purposely not conducted assuming that their importance for secular growth should be fixed in empirical surveys. To estimate structure parameters of the TFP equation the ”from a whole to a detail” modeling strategy was applied. Fourteen indirect factors of a GDP growth were identified and analyzed.

The aim of the article is to analyze Poland’s foreign debt in years 1995–2009 in relation to changes occurred in earlier years as well as definition of economic dangers in the next future. Disadvantageous balance of payments reduces possibilities to run up a debt on international markets although high currency reserves allow Poland to settle current liabilities without problems. The foreign debt risk growths but it is as before relatively low. However disadvantageous macro-economic development conditions can change this situation.

Authors: Rak Grzegorz , Pstrocka-Rak Małgorzata
Published: February 2024

The majority of significant Polish papers concerning the tourist regionalization of Poland are conceptually connected with tradition of physical geography, which focuses on the features of landscape. Thus the tourist flow is treated as a less important factor, whereas the qualities and attractions of the geographical environment are appreciated. This reason makes the functional and space-time analyses difficult. Therefore the authors made this paper which touches the problem of tourist regionalization of Poland based on statistics of tourist movement and tourist infrastructure. 21 regions were specified. The most important are: coastal region, Carpathian, Sudetian and four lakeland regions.

Transposition — retelling — translation: the destiny of Areopagitica in Slavia Orthodoxa
Authors: Nikolaeva Nataliya G. , Yermoshin Anton V. , Volskaya Anastasiya S.
Published: February 2024

The article undertakes a conceptual analysis of the challenges associated with translating works from the Corpus Areopagiticum, a collection of theological treatises attributed to Dio­nysius the Areopagite from the 1st century. However, these works are unequivocally associat­ed with early medieval Eastern Christian mystical-theological thought, presumably from the turn of the 5th—6th centuries. These texts first appeared in the Slavic Orthodox area in 1370, and subsequent translations emerged at the end of the 17th century, in the 18th and 19th centuries, and, most recently, in contemporary times. The authors introduce a set of criteria that facilitate the differentiation of the analyzed texts into distinct types of text transmission, namely transposition, retelling, and translation. These criteria are founded on factors such as the dominant translation strategy, the approach to the source language, and the textual tradi­tion. The primary research methodology involves a diachronic analysis of linguistic material, employing comparative, stylistic, and textual analysis within the theolinguistic paradigm. The hypothesis posited in the article is substantiated based on empirical evidence. Moreover, the article draws conclusions regarding the impact of general linguistic changes on the nature of translations. This includes shifts in the role and status of the Church Slavonic language, the conditions contributing to the formation of a new literary language, and the inevitable influence of broader cultural and civilizational factors. The paper also explores the tradition of translating otherness, a practice that persists in contemporary times.
Geo-energy and Activities, Energy Policy of the Mongolia: Problems, Challenges, and Solutions
Authors: Dashzevge Myagmarsuren
Published: February 2024

This article summarizes research reports on the foundations of geo-energy study theory, dynamic change and transition in international relations or geopolitical fields, geo-economics fragmentation, and the new distribution of powers in the region. Based on the situation analysis, I tried to explore the dangers and risks facing the national security of the country. Moreover, policy analysis was conducted on energy strategy policy that stated mid and long-term development concepts of the country. One can distinguish the Mongolian energy strategy into two objectives:

To establish and maintain energy security;
To keep and grow in the role of an energy-market player.

According to geo-energy theory, the Mongolian energy policy can be divided into three separate fields, such as 1) Steps according to the changes and risks associated with world order; 2) Steps according to the third-neighbor policy; and 3) Steps according to cooperation with two neighbors. The dynamics of the change in the world energy sector have naturally dragged Mongolia into its competitive field as a country that has tremendous resources of clean energy and critical minerals. Although Mongolia has the potential to be a big player in the field, it has to play along with super players in the field and consider their interests and arrangements. To attract foreign investment and high technology, Mongolia should employ an attractive policy in the long term. It requires the country to be active in the world energy field and to calculate future energy trends, dynamics, and arrangements correctly.
