Background and purpose
Despite the widespread adoption of various preventive measures since the spread of COVID-19, there remains a lack of consensus on universally acknowledged best practices. However, the significance of vaccination has risen to prominence as a paramount preventive strategy. Numerous investigations have demonstrated vaccine effectiveness against the omicron strain in severe disease and symptomatic disease, however, the scope of research pertaining to vaccine effectiveness in preventing infection is presently limited. Therefore, the current study aimed to evaluate COVID-19 mRNA (Pfizer-BioNTech BNT162b2 or Moderna mRNA-1273) vaccine effectiveness in preventing infection.

Methods
We conducted a test-negative case-control study using a dataset of 117,335 individuals. These data were collected through the COVID-19 J-SPEED form in the PCR center at Hiroshima Prefecture, Japan from 1 February to 17 March 2022. We estimated propensity score matching for vaccine status based on participants’ demographic characteristics. Subsequently, odds ratio was calculated from logistic regression to determine the association between vaccination status and test positivity rate adjusting for symptoms, exposure to close contact, and previous infection history. Vaccine effectiveness was defined as (1 –aORs) ×100%.

Results
The PCR test positivity rates were 7.9%, 4.5%, and 2.8% for the non-vaccinated (non-vaccinated, vaccinated with a single dose, and vaccinated with two doses less than 14 days ago), vaccinated with two doses (vaccinated over 14 days ago), and three doses, respectively. In unadjusted and adjusted analyses, vaccine effectiveness of two doses against infection were 38.5% (95% confidence interval [CI]: 32.8%–43.8%) and 34.7% (95%CI: 28.4%–40.4%), respectively, compared to non-vaccinated group. Vaccine effectiveness of three doses were 33.8% (95%CI: 25.0%–41.5%) and 26.4% (95%CI: 16.4%–35.2%), respectively, compared to those vaccinated with two doses.

Conclusions
These results illustrate the protective effect of mRNA vaccines against Omicron strain infections and emphasize the significance of completing the suggested vaccination schedule.

Background
Evaluating moral principles in the Society of Medical Sciences and health care workers (HCWs) is imperative due to their direct contact with the community and the significant impact of their attitudes and decisions on people’s lives. This study aimed to determine the components related to ethical decisions in medical sciences students.

Methods
One thousand two hundred thirty-five eligible students in the Alborz University of Medical Sciences participated in this descriptive study. We gathered their socio-demographic information, assessed their moral reasoning, and used the ethical decisions questionnaire, Lutsen moral sensitivity questionnaire, and general health questionnaire (GHQ) for data gathering. The data were analyzed with SPSS software version 25 and LISREL version 8.8.

Results
According to the path analysis test findings, ethical reasoning significantly correlated with ethical decision-making (B = 0.40). The number of clinical courses passed, moral sensation (moral sensitivity), and the total number of passed academic semesters had the greatest positive and negative association with ethical decision-making, respectively. (B = 0.54), (B = 0.524) and (B = -0.11).

Conclusion
Based on the findings of the moral reasoning test, the moral sensation was associated with ethical decision-making, which indicates the necessity of attending to ethical aspects, promoting moral reasoning, sensitivity, and students’ accuracy.

Authors: Gao Shuang , Tang Liyun , Ma Jiayi , Wang Kaiming , Yao Hua , Tong Jinjin , Zhang Hua 
Published: April 2024

Objectives
The goal of this investigation was to identify the main compounds and the pharmacological mechanism of the traditional Chinese medicine formulation, Gong Ying San (GYS), by infrared spectral absorption characteristics, metabolomics, network pharmacology, and molecular-docking analysis for mastitis. The antibacterial and antioxidant activities were determined in vitro.

Methods
The chemical constituents of GYS were detected by ultra-high-performance liquid chromatography Q-extractive mass spectrometry (UHPLC-QE-MS). Related compounds were screened from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP, http://tcmspw.com/tcmsp.php) and the Encyclopedia of Traditional Chinese Medicine (ETCM, http://www.tcmip.cn/ETCM/index.php/Home/) databases; genes associated with mastitis were identified in DisGENT. A protein-protein interaction (PPI) network was generated using STRING. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment screening was conducted using the R module. Molecular-docking analyses were performed with the AutoDockTools V1.5.6.

Results
Fifty-four possible compounds in GYS with forty likely targets were found. The compound-target-network analysis showed that five of the ingredients, quercetin, luteolin, kaempferol, beta-sitosterol, and stigmasterol, had degree values >41.6, and the genes TNF, IL-6, IL-1β, ICAM1, CXCL8, CRP, IFNG, TP53, IL-2, and TGFB1 were core targets in the network. Enrichment analysis revealed that pathways associated with cancer, lipids, atherosclerosis, and PI3K-Akt signaling pathways may be critical in the pharmacology network. Molecular-docking data supported the hypothesis that quercetin and luteolin interacted well with TNF-α and IL-6.

Conclusions
An integrative investigation based on a bioinformatics-network topology provided new insights into the synergistic, multicomponent mechanisms of GYS’s anti-inflammatory, antibacterial, and antioxidant activities. It revealed novel possibilities for developing new combination medications for reducing mastitis and its complications.

O INSTITUTO DE PESQUISAS E ESTUDOS AFRO-BRASILEIROS (IPEAFRO) COMO CASA DE MEMÓRIA DECOLONIAL
Authors: Reis Heverton , Neta Olívia 
Published: April 2024

A memória é uma ferramenta importante para a construção de uma história mais equânime, que valoriza as contribuições desses grupos para a sociedade. O Instituto de Pesquisas e Estudos Afro-Brasileiros (Ipeafro) é uma instituição que atua como casa de memória decolonial para as relações étnico-raciais. Por tal, busca-se responder a seguinte pergunta: como o acervo do Ipeafro constitui-se como lugar de memória à cultura afro-brasileira? Dialoga-se com os conceitos de memória e decolonialidade. O corpus da pesquisa abrange o material disponível no acervo entre textos, imagens e produção intelectual, destacando a trajetória e legado do Abdias Nascimento no processo de criação do Ipeafro. Por meio de suas pesquisas, estudos e documentos, o Ipeafro busca descolonizar o pensamento e construir uma história que vislumbre as perspectivas e experiências dos negros. Além disso, o Ipeafro promove ações de conscientização e formação sociorracial, objetivando combater o racismo e as desigualdades étnico-identitárias, ajudando, no que lhe concerne, para a construção de uma narrativa mais inclusiva sobre a história do negro no Brasil, ao tempo que valoriza a cultura e as contribuições dos afrodescendentes para a sociedade. Percebe-se, portanto, o Ipeafro como casa de memória decolonial de resistência e existência identitária negra, e possibilita narrativas contra coloniais sobre o negro.
Research on optimal design of pleated cheongsam based on Kano–HOQ–Pugh model
Authors: Jiang Runtian , Jin Peng , Xu Xubing 
Published: April 2024

Abstract
As a kind of dress combining traditional and modern design, pleated cheongsam is becoming increasingly popular among Chinese users. However, the current design of pleated cheongsam has the problem of mismatch with users’ modern aesthetics and demands, which causes serious homogenization of pleated cheongsam and low sales volume. Therefore, the optimal design of pleated cheongsam was discussed from three aspects:consumer demands, design features, and comprehensive evaluation. The Kano model was used to sort out 12 user demands in three aspects: functionality, usability, and emotion. The House Of Quality (HOQ) method was used to establish the mapping matrix of “user demand-design requirement,” and the priority of 11 design requirements was determined. Finally, the best optimization proposal was screened and evaluated by the Pugh matrix and the live streaming data of pleated cheongsam brand. The experimental results demonstrate that the Kano–HOQ–Pugh model provides a scientific and engineered attribute framework for improving the acceptability and attractiveness of pleated cheongsam and provides a theoretical basis for brands to develop pleated cheongsams with ethnicity, modernity, and differentiation.
Understanding the separation of trivalent lanthanides and actinides using multiple diglycolamide-containing ligands: a review
Authors: Bhattacharyya Arunasis , Mohapatra Prasanta K. , Verboom Willem 
Published: April 2024

Abstract
The complexation and separation behaviour of trivalent actinides and lanthanides with various multiple diglycolamide (DGA) group-containing ligands are compiled in the present review. The DGA arms are anchored on various scaffolds, viz., C- and N-pivot tripodal backbones, benzene-centred tripodal backbones, calix[4]arene, pillar[5]arene and azamacrocycle scaffolds. Dendrimers of different generations having DGA arms were also evaluated for the extraction and complexation studies of trivalent actinide and lanthanide ions. The extraction efficiency of the DGA units increases significantly when they are grouped together on a single backbone/scaffold. Furthermore, the selectivity was found to improve in many cases, particularly with respect to the UO2
2+ ion. This is very important for the development of suitable ligands for the extraction/separation of the actinide and lanthanide ions. Combined experimental, luminescence and DFT studies on the complexation of trivalent actinides and lanthanides with these DGA-based ligands are quite useful to understand their extraction and separation behaviour and this review article gives a critical analysis of the results available in the literature.
When Gorillas Strike: Constitutional Protection of Non-Market-Institutions in Labor Law
Authors: Hensel Isabell 
Published: April 2024

Abstract
The “wildcat strike” against the poor working conditions of the bike couriers of the delivery service Gorilla at the beginning of 2021 ended in numerous dismissals by the employer. The trade unions did not support the strike, so that participation in the work stoppage was deemed unlawful by the courts. Under German law, strikes are only permitted as a means of exerting pressure in collective bargaining. However, it must be asked whether, with the changes in forms of employment and the associated limits to trade union representation of interests, it is still justified to regard the right to strike exclusively as an appendage of collective bargaining autonomy. Not only the pressure of international law, but also Gunther Teubner’s concept of non-market institutions as necessarily resistant collective actors against economic profit pressures call for the further development of legal protection of collectivities. Alternative labor struggles for the often precarious conditions of increasing mobile, digitalized and transnational gainful employment would then have to be recognized under certain conditions.
History beyond Recovery: Julius Eastman and the Challenge of the Heterological
Authors: Mendez Matthew 
Published: April 2024

Abstract
This article examines the improvisative activities of the gay Black composer-vocalist Julius Eastman (1940–90), whose life and works have lent themselves in recent years to efforts to diversify histories of experimentalism and new music. These initiatives have obscured the fact that Eastman repeatedly engaged with jazz improvisation, a subject about which the secondary literature is mostly silent. Guided by George Lewis’s theorization of “Afrological” and “Eurological” improvisative modes, I examine a series of moments in Eastman’s improvisative trajectory that resist subsumption under either pole. Inasmuch as his improvisative work turned on an identity-affirming, self-expressive “Romantic ideal” that was in fashion with neither Eurological, post-Cagean experimentalism nor Afrological “loft” jazz, his engagements with both tended to lead to impasse. This suggests the utility of a third term, the “heterological.” I argue that Eastman’s heterological improvisative practice followed the logic of disidentification, or minoritarian recodings of hegemonic, exclusionary social texts. The article also explores the progressive radicalization of Eastman’s heterology, and his eventual renunciation of music-improvisative identity work. By the mid-1980s, Eastman was instead embracing practices of self-shattering and sacrifice, one goal of which was to place himself, literally, beyond historical recovery. The transgressive heterology of his personal life, and his profound indifference to archivization, pose deep challenges to musicology’s impulse to “recover” marginalized figures. Eastman’s ultimate rejection of futurity unsettles the grounds for meaningful historiographical identification with his past, since it is by no means clear that our present is any future he would have ever wished to inhabit.
Unionsrechtliche Pflicht der Zahlungsdienstleister zum Kundenidentifikator-Namensabgleich – Ökonomische Implikationen und rechtliche Friktionen
Authors: Fritz Dennis 
Published: April 2024

Zusammenfassung
Schon seit der Umsetzung der ersten Zahlungsdiensterichtlinie (PSD) in nationales Recht sind Zahlungsdienstleister nicht mehr verpflichtet, im Überweisungsverkehr einen Kontonummer-Namensabgleich durchzuführen. Mit der Verordnung zur Änderung u. a. der SEPA-Verordnung und – sollte der Unionsgesetzgeber diese ebenfalls verabschieden – der Verordnung über Zahlungsdienste im Binnenmarkt (PSR) ist ein grundlegender Wandel im Zahlungsdiensterecht verbunden. Danach sind nämlich Zahlungsdienstleister in der Regel verpflichtet, vor der Autorisierung eines Überweisungsauftrags den vom Zahler angegebenen Kundenidentifikator und Namen abzugleichen. Der Beitrag befasst sich mit den genannten europäischen Gesetzgebungsakten. Dabei geht es zum einen um ökonomische Erwägungen, die die Europäische Kommission zu ihren Vorschlägen veranlasst haben. Zum anderen sind die mit den derzeitigen Fassungen verbundenen rechtlichen Probleme zu untersuchen.

Published: April 2024

The main purpose of this paper is to introduce a notion of
fuzzifying bornivorous sets of fuzzifying bornological linear
spaces. In particular, we provide an example of fuzzifying
bornivorous sets on a fuzzifying topological linear space with its
von Neumann bornology. Furthermore, the description of fuzzifying
open sets of fuzzifying bornological linear spaces is showed and its
equivalent illustration is discussed as well. In addition, we study
the dual relationship of fuzzifying open and close sets. The
fuzzifying topological space induced by fuzzifying open sets is also
discussed.

Introdução: O ligamento cruzado anterior é um dos principais ligamentos do joelho, frequentemente mais suscetível às lesões devido à sua posição central e seu papel vital na estabilização desta articulação. A força do quadríceps desempenha papel crucial, com função de absorção de impacto, auxiliando na redução de carga.
Objetivo: Avaliar o volume e a força do músculo quadríceps antes e após a reconstrução do ligamento cruzado anterior do joelho, sua correlação e quais as variáveis preditivas da força muscular pré e pós-operatória.
Método: Coorte prospectiva de 37 pacientes avaliados no pré-operatório e com 4 meses após a operação, por meio de ressonância magnética e dinamometria isocinética. As medidas do membro submetido à operação foram comparadas ao membro contralateral como controle.
Resultado: O volume do músculo quadríceps foi de 65,2+13,4cm3 antes e de 63,4+15,9 cm3 após, significativamente menor no controle nos 2 momentos, com redução de 3,0cm3 (4,1%) no pré e 7,8 cm3 no pós (12,0%). A força muscular foi de 105,5+29,9N/m antes e de 100,9+28,6N/m após, significativamente menor no membro operado (126,4+28,2N/m e 129,6+27,6N/m, p<0,001). Esta redução foi semelhante nos 2 momentos de avaliação, em média de 17,5N/m (16,3%) no pré e de 22,8N/m (22,5%) no pós. A perda de força foi maior que a perda de volume muscular, sendo que o volume muscular e o tempo da lesão do ligamento cruzado anterior foram os principais determinantes da força muscular no pré. A força no pós foi determinada principalmente pela do pré.
Conclusão: A perda de força muscular foi 4 vezes maior que a perda de volume no pré e 2 vezes maior no pós, indicando início da recuperação com 4 meses no pós-operatório.
POSSIBILITY OF USING A PRODUCT OF NATURAL POLYMER CHEMICAL PROCESSING TO IMPROVE CONCRETE MIXTURE PLASTICIZING PROPERTIES
Authors: Dimitriev Evgeniy N. , Teptereva Galina A. 
Published: April 2024

In modern construction, increasing attention is paid to the search for new materials and technologies that can improve the properties of concrete mixtures. Chemical additives such as superplasticizers and air bubbles are used to improve the workability of the concrete mixture and increase its plasticity. The strength characteristics of concrete mixtures are an important criterion in solving issues related to the profitability of the construction process. The use of plasticizers and hardening accelerators makes it possible to obtain high-strength mixtures with unique characteristics and guarantee high quality construction. Lignosulfonate-based additives have unique properties that can significantly increase the plasticizing characteristics of a concrete mixture. Tests for strength, frost resistance, resistance to aggressive environments, bending and torsion make it possible to evaluate the properties of concrete with lignosulfonate-based additives.While researching, several samples of concrete mixtures with different compositions were prepared. In the experimental testing laboratory, under conditions close to production conditions, a series of experiments was carried out with samples of concrete mixtures for compliance with the requirements of regulatory documents for concrete quality: a lignosulfonate-based additive with concentrations 0.5 %, 1 %, 1.5 % was added to the concrete mixture of compressive strength class B15 to volume 2286 kg/m3.It has been established that the use of a product of natural polymer chemical processing – lignosulfonate – improves the plasticizing properties of concrete mixtures with a two to fivefold increase in mobility and without slowing down the hardening of concrete both in the early (3 days) and late (10–15 days) periods of hardening.It has been revealed that the use of an additive based on lignosulfonate helps to increase the strength of concrete by 25–30 % compared to known plasticizing additives.It has been calculated that the use of a lignosulfonate-based additive helps to reduce cement consumption by 12–15 %.It has been shown that the addition of 1 % lignosulfonate reduces water absorption by 9 % and increases the average strength over 7 days by 10 %, which makes it possible to use the practical results of the research to develop new concrete compositions with improved technical characteristics.
