Small-Scale Cosmology Independent of the Standard Model
Authors: Burde Georgy I.
Published: April 2024

‘Small-scale cosmology’ is a theory designed to incorporate the linear redshift versus distance relation, which is inferred from observations, into the theoretical framework independent of the global Robertson–Walker–Friedman (RWF)-type models. The motivation behind this is that the RWF cosmological models, based on the assumptions of homogeneity and a constant matter density, as well as the concept of expanding space inherent to them are not applicable on the scales of observations from which the linear Hubble law is inferred. Therefore, explaining the Hubble law as the small redshift limit of the RWF model or as an effect of expanding space is inconsistent. Thus, the Hubble linear relation between the redshift of an extragalactic object and its distance should be considered an independent law of nature valid in the range of the distances where the RWF cosmology is not valid. In general, the theory, based on that concept, can be developed in different ways. In the present paper, ‘small-scale cosmology’ is formulated as a theory operating in the (redshift–object coordinates) space, which allows developing a conceptual and computational basis of the theory along the lines of that of special relativity. In such a theory, the condition of invariance of the Hubble law with respect to a change in the observer acceleration plays a central role. In pursuing this approach, the effectiveness of group theoretical methods is exploited. Applying the Lie group method yields transformations of the variables (the redshift and space coordinates of a cosmological object) between the reference frames of the accelerated observers. In this paper, the transformations are applied to studying the effects of the solar system observer acceleration on the observed shape, distribution and rotation curves of galaxy clusters.
Brief Histories of Retroviral Integration Research and Associated International Conferences
Authors: Grandgenett Duane P. , Engelman Alan N.
Published: April 2024

The field of retroviral integration research has a long history that started with the provirus hypothesis and subsequent discoveries of the retroviral reverse transcriptase and integrase enzymes. Because both enzymes are essential for retroviral replication, they became valued targets in the effort to discover effective compounds to inhibit HIV-1 replication. In 2007, the first integrase strand transfer inhibitor was licensed for clinical use, and subsequently approved second-generation integrase inhibitors are now commonly co-formulated with reverse transcriptase inhibitors to treat people living with HIV. International meetings specifically focused on integrase and retroviral integration research first convened in 1995, and this paper is part of the Viruses Special Issue on the 7th International Conference on Retroviral Integration, which was held in Boulder Colorado in the summer of 2023. Herein, we overview key historical developments in the field, especially as they pertain to the development of the strand transfer inhibitor drug class. Starting from the mid-1990s, research advancements are presented through the lens of the international conferences. Our overview highlights the impact that regularly scheduled, subject-specific international meetings can have on community-building and, as a result, on field-specific collaborations and scientific advancements.

Published: April 2024

Background: Myopia management contact lenses have been shown to successfully decrease the rate of eye elongation in children by changing the peripheral refractive profile of the retina. Despite the efforts of the scientific community, the retinal response mechanism to defocus is still unknown. The purpose of this study was to evaluate the local electrophysiological response of the retina with a myopia control contact lens (CL) compared to a single-vision CL of the same material. Methods: The retinal electrical activity and peripheral refraction of 16 eyes (16 subjects, 27.5 ± 5.7 years, 13 females and 3 males) with myopia between −0.75 D and −6.00 D (astigmatism < 1.00 D) were assessed with two CLs (Filcon 5B): a single-vision (SV) CL and an extended-depth-of-focus (EDOF) CL used for myopia management. The peripheral refraction was assessed with an open-field WAM-5500 auto-refractometer/keratometer in four meridians separated by 45° at 2.50 m distance. The global-flash multifocal electroretinogram (gf-mfERG) was recorded with the Reti-port/scan21 (Roland Consult) using a stimulus of 61 hexagons. The implicit time (in milliseconds) and response density (RD, in nV/deg2) of the direct (DC) and induced (IC) components were used for comparison between lenses in physiological pupil conditions. Results: Although the EDOF decreased both the HCVA and the LCVA (one and two lines, respectively; p < 0.003), it still allowed a good VA. The EDOF lens induced a myopic shift in most retinal areas, with a higher and statistically significant effect on the nasal retina. No differences in the implicit times of the DC and IC components were observed between SV and EDOF. Compared with the SV, the EDOF lens showed a higher RD in the IC component in the foveal region (p = 0.032). In the remaining retinal areas, the EDOF evoked lower, non-statistically significant RD in both the DC and IC components. Conclusions: The EDOF myopia control CL enhanced the response of the inner layers of the fovea. This might suggest that, besides other mechanisms potentially involved, the central foveal retinal activity might be involved in the mechanism of myopia control with these lenses.

Authors: Zhou Yan , Cui Xiangbin , Dai Zhenxue , Zhou Xiaobing , Li Lin , Jiang Su , Sun Bo
Published: April 2024

Subglacial lakes and hydrological systems play crucial roles in Antarctic subglacial hydrology, water balance, subglacial geomorphology, and ice dynamics. Satellite altimetry has revealed that some recurrent water exchange occurs in subglacial lakes. They are referred to as ’active lakes’, which prominently influence a majority of subglacial hydrological processes. Our analysis indicates that active subglacial lakes are more likely to be situated in regions with higher surface ice flow velocities. Nevertheless, the origin of subglacial lakes still remains enigmatic and uncertain. They could have potential associations with geothermal heat, ice sheets melting, and ice flow dynamics. Subglacial lake drilling and water sampling have the potential to provide valuable insights into the origin of subglacial lakes and subglacial hydrological processes. Moreover, they could also offer unique opportunities for the exploration of subglacial microbiology, evolution of the Antarctic ice sheets, and various fundamental scientific inquiries. To date, successful drilling and sampling has been accomplished in Lake Vostok, Lake Mercer, and Lake Whillans. However, the use of drilling fluids caused the water sample contamination in Lake Vostok, and the drilling attempt at Lake Ellsworth failed due to technical issues. To explore more of the conditions of the Antarctic subglacial lakes, the Lake Centro de Estudios Científicos (Lake CECs) and Lake Snow Eagle (LSE) drilling projects are upcoming and in preparation. In this study, we aim to address the following: (1) introduce various aspects of Antarctic subglacial lakes, subglacial hydrological elements, subglacial hydrology, and the interactions between ice sheets and the ocean; and (2) provide an overview and outlook of subglacial lakes drilling projects.

Published: April 2024

A multidisciplinary study, involving hydrogeological, geochemical, and mineralogical analyses, was conducted to define the evolution of thermal mineral springs in the Sabatini Volcanic District (SVD) (Central Italy) in a historic period. The outcomes were integrated with the archeological findings to improve the knowledge of the evolution of Veii, a settlement established since the Iron Age and later expanded by Etruscans and Romans. During the archeological excavations, water-related buildings were identified, especially at the Campetti Southwest site in the Veii settlement. Votive inscriptions also suggest the presence of buildings linked to sacred waters, even if a clear definition of the source and type of water is missing. In the SVD, some low-flow thermal mineral springs are present as a result of the mixing of thermal and CO2-rich groundwater from the deep carbonate aquifer and the cold, shallow volcanic aquifer. Mineralogical and chemical analyses characterized the travertine and Fe-hydroxide deposits on Roman tanks and walls in Campetti Southwest and in a nearby ancient Roman bath along the Valchetta River. These deposits showed different relative concentrations of sedimentary and volcanic-related elements, testifying a geochemical evolution of the groundwater mixing and the presence of a paleothermal mineral spring in Campetti Southwest.

Published: April 2024

Low-impact developments (LIDs) have emerged as effective strategies for mitigating the adverse impacts of urbanization on river environments. This study aims to enhance river environment quality by examining the effects of LIDs and land use/cover change (LUCC) in the context of river environment and hydrological conditions. Using the Stormwater Management Model (SWMM) in an urban river setting, the study investigates the impact of LIDs on urban river water volume. An analysis of river runoff quality and quantity is conducted, followed by the development of an optimal river water regulation scheme through a multi-objective ecological scheduling model. The results reveal that the incorporation of LIDs can substantially decrease river runoff yield for varying recurrence periods of design rainstorms. Consequently, the flood peak reduction rate ranged from 10% to 18%, and the flood volume experienced a reduction of 10–29% in the study area. The combination of river water regulation, LIDs and LUCC leads to a decrease in river water volume within the lower river channel by up to 47% especially in a typical dry year and dry season, accompanied by a decline in river flow velocity and water self-purification capacity. A risk-based multi-objective stochastic optimization model is employed to ensure sustainable management of urban river runoff in terms of both quantity and quality. This research contributes to the advancement of knowledge in sustainable basin management practices and offers practical insights for policymakers involved in the management of water resources and environmental conservation in semi-arid basins.
Response of Floods to the Underlying Surface Changes in the Taojiang River Basin Using the Hydrologic Engineering Center’s Hydrologic Modeling System

Published: April 2024

Due to underlying surface changes (USCs), the changes in the Taojiang River Basin’s flood generation conditions could impact the flooding process in the basin. However, most studies have typically focused on either land-use changes (LUCs) or soil and water conservation measures (SWCMs) to assess the impact of the USCs on floods, which may not provide a more comprehensive understanding of the response of floods to the USCs. To investigate how the USCs have altered the floods in the Taojiang River Basin, located upstream of Poyang Lake, China, the HEC-HMS model, which incorporates the influence of the USCs into the parameter calibration, is established in this study to investigate the flood processes on an hourly scale. The flood peak and the maximum 72 h flood volume are selected as two indexes and are applied to analyze the changes in floods caused by the USCs. The 1981–2020 period is divided into three sub-periods (i.e., 1981–1992, 1993–2007, and 2008–2020) based on the conditions of the USCs. It is found that the two indexes have exhibited decreasing trends, mainly due to the USCs during 1981–2020. Benchmarked against the baseline period of 1981–1992, the two indexes decreased by 3.06% (the flood peak) and 4.00% (the maximum 72 h flood volume) during 1993–2007 and by 5.92% and 7.58% during 2008–2020. Moreover, the impacts of the LUCs and SWCMs are separated through parameter adjustments in the model, revealing that the SWCMs played a dominant role in the USCs in the Taojiang River Basin. The quantification and assessment of the impact of the USCs on floods of different magnitudes revealed that the influence decreases with increasing flood magnitude. The results of this study improve our understanding of how USCs affect the flooding process and therefore provide support for flood control management under changing environments.

Published: April 2024

Antibiotics in the aquatic environment are of great concern as novel contaminants. In this study, we investigated the occurrence, distribution, potential sources, and risk assessment of antibiotics in an interconnected river–wetland–lake system. Thirty-three target antibiotics, including sulfonamides (SAs), macrolides (MLs), fluoroquinolones (FQs), tetracyclines (TCs), and chloramphenicol (CLs) belong to five common groups of antibiotics, were tested from water samples collected in the Panlong River, Xinghai Wetland, and Lake Dian (or Dianchi). Mass spectrophotometry was used to detect the target antibiotics, and the water quality parameters were measured in situ. We found four antibiotics, lincomycin (LIN), trimethoprim (TMP), sulfamethoxazole (SMX), and ofloxacin (OFL), with relatively low concentrations at the ng/L level, and detection rates among sample sites ranged from 42.3% to 76.9%, with maximum concentrations of 0.71 ng/L~5.53 ng/L. TMP was not detected in the Panlong River but appeared in the wetlands and Lake Dian. Midstream urban areas of the Panlong River showed the highest pollution among sites. Antibiotic concentrations were positively correlated with total nitrogen (TN) (p < 0.05) and showed some negative correlation with pH, salinity, and DO. According to the risk assessment, antibiotics in water do not pose a threat to human health and aquatic ecosystems, but a potentially harmful combined effect cannot be excluded. Our research offers a geographical summary of the distribution of antibiotics in urban river, wetland, and lake ecosystems in the plateau (PWL), which is important for predicting the distribution characteristics of antibiotics in the plateau water environment and establishing a standardized antibiotic monitoring and management system for the government.

Published: April 2024

The article substantiates the criteria for expert measurement of the investment and innovation attractiveness of regions in the post-war transformation of Ukraine, which are the basis of a multi-component assessment methodology focused on a marketing approach to understanding the issues of formation and development of the attractiveness of the region. It is emphasized that traditionally investment attractiveness is inseparable from innovative attractiveness, but each of them is an independent economic category - with its own goals, factors, signs, characteristics, assessment methods, formation and development mechanisms. The need to apply a multi-component method of assessing the attractiveness of the region, which involves the assessment of statistical indicators, expert assessment of qualitative criteria of attractiveness, which specify and more adequately characterize the attractiveness of the region for defined target audiences, and marketing research, the directions of which are determined by the problems of target audiences, has been confirmed. It is proposed to include an additional index «Index of damage and destruction caused to regions and communities during a full-scale invasion and needs for reconstruction and development» in the methodology for assessing the region's investment attractiveness in the statistical assessment block, which should be filled with relevant indicators in the future. It is noted that the objectively existing characteristics of the region are not always a measure of its investment potential, so it is necessary to take into account the subjective factor in the process of making an investment decision, that is, its expert dimension. It was concluded that the marketing approach to the investment attractiveness of the region and its expert assessment will allow taking into account the judgments, ideas, preferences and opinions of specialists in regional studies, business representatives, regional and public leaders, scientists, decision-makers, etc., who have official, unofficial, sometimes with hidden information about the manifestation of the characteristic features of the region, etc.
INVESTIGATION OF THE PROPERTIES OINVESTIGATION OF THE PROPERTIES OF CLAY RAW MATERIALS BY METHODS OF PHYSICO-CHEMICAL ANALYSIS
Authors: Ushnickaya H. , Mestnikov A.
Published: April 2024

The article presents the results of the study of the properties of clay raw materials using modern methods of physico-chemical analysis: X-ray fluorescence analysis (XRF), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and thermal analysis. Two types of clay raw materials based on the color of the ceramic shard were considered: light-burning and red-burning clays. The studied clay raw materials contain a small amount of clay minerals and a high content of dusty particles, belong to moderately plastic and medium plastic clays and loams. X-ray spectral analysis allowed to determine the chemical quantitative composition of the main oxides of clay raw materials. Thermal analysis of natural clay raw materials, which have a polymineral composition, reveals exothermic and endothermic effects characteristic of the studied minerals – montmorillonite and kaolinite. According to the mineral composition, the clay raw materials of Central Yakutia are polymineral, with the main clay minerals being montmorillonite and kaolinite, and quartz, calcite, chlorite, minerals from the mica and feldspar groups, and mixed-layer minerals found as impurities. The low quality of the clay raw material suggests that further research should be conducted to improve the technological and physical-mechanical properties of ceramic products made from local clay raw material. In the design of raw material mixtures, local natural and man-made mineral raw materials can be used.

Authors: Tesler K. , Dodonova M.
Published: April 2024

Congestion in megacities due to extreme population density and insufficient transport infrastructure leads to serious consequences. Traffic jams not only cause inconvenience for passengers, but also have a negative impact on the economy and the environment. In order to stabilize the situation and eliminate the negative impact of inefficient traffic on the life of megacities, it is necessary to review previously used techniques and identify new measures to solve the problem. Research methods include a review and systematization of information sources related to economic, urban planning and social aspects of transport infrastructure. By summarizing and comparing the results of domestic and foreign experience in eliminating traffic congestion, outdated methods were identified and trends in the development of design thinking in the field of construction of road spaces were identified. Current ratings of transport systems make it possible to fix a list of leaders with an effective policy for the development of public transport. Conceptual modeling demonstrates modern features of the placement of road networks within the city. To improve urban mobility, an integrated approach is required: active implementation of innovations in the transport structure, changing urban planning thinking, reviewing management impacts, changing priorities in favor of the needs of pedestrians and informing the public, involving it in the modernization process. These techniques will create modern and smart urban spaces that meet the needs of modern society.
ORGANIZATION OF THE ARCHITECTURAL ENVIRONMENT OF PUBLIC SPACES IN A MOUNTAIN LANDSCAPE (USING THE EXAMPLE OF CHONGQING, CHINA)
Authors: Ladik E. , Xing Renjie
Published: April 2024

The mountain landscape distinguishes the location of urban routes, the functional-spatial structure and layout of public areas from the design of an urban environment on flat terrain. This study examines the issues of rational use of urban areas in conditions of complex terrain using the example of the territory of the largest city of Chongqing, located in the central part of China. The research is based on an integrated approach, methods of urban planning analysis and functional-spatial modeling. Various aspects of the transformation of complex natural landscapes to expand public urban spaces and form their identity are analyzed using the example of public spaces in the structure of high-density residential development in Chongqing. The study identified the characteristic problems of the planning organization of public areas on difficult terrain (insufficient insolation, lack of green areas, non-standard location of transport infrastructure, irrational organization of pedestrian traffic, lack of public access to public areas, isolation and incoherence of public spaces, etc.). Functional planning models for the organization of public recreational spaces are proposed, which are promising for use both in areas of existing high-density development and for the development of undeveloped territories in the mountainous regions of China. Prospective directions for the development of public spaces in the Baixiangju residential area in Chongqing have been identified.
Les inexplicables silences de L’« Encyclopédie» envers le mot « porcelaine»
Authors: Albis Antoine d'
Published: April 2024

The “Encyclopédie” of Denis Diderot and Jean d’Alembert was printed between 1751 and 1772. It consisted of 74 000 entries distributed in 17 volumes chronologically published accordingly to the alphabet. The word “porcelain” comes up in volume VI in 1756. The article was entrusted to chevalier de Jaucourt who edited it alongside 15 000 other entries. Jaucourt does not appear to be the most capable author for this task. He seems to have indeed satisfied himself in unsuccessfully rewriting the two of François Xavier and most obscure letters sent from China in 1712 and 1722. This research tries to list all the other capable personalities, living at this time, who could have been asked to edit this entry. The reason why the porcelain of Sèvres, at its apogee by then and object to a great and indisputable success under Louis XV, is not mentioned and will be discussed.

Le femmine sapute di Anna Banti. Da Artemisia a Il bastardo
Authors: Rivetti Sonia
Published: April 2024

Between 1980 and 1981 on the third page of the «Corriere della Sera» Anna Banti published eleven portraits of women painters. The column opens with an article on Sofonisba Anguissola, the author of Autoritratto al cavalletto, a symbol of the reclamation of female identity which calls into question the role assigned to women in the 16th century. It is the culmination of a reflection that began in 1947 with the novel Artemisia. Famous in the news of the time for having been at the center of a rape trial, Artemisia Gentileschi is read as the figure responsible for a talent, the painting, defended at the cost of a loneliness that accompanies her until death. Le donne muoiono is the title of a collection of four stories published in 1951. In the last one, Lavinia fuggita, the theme of vocation returns. In 18th century Venice where composing music was considered a male profession, Lavinia cannot give up the natural inclination to manipulate the scores with jokes of her own invention. The latest female character who refuses to take the traditional way of marriage is Cecilia De Gregorio, protagonist of Il bastardo, the novel published in 1953. Through an austere path but not without doubts, it tells the story of a woman who finds fulfillment in her studies and becomes an engineer head of a company

Authors: Stetsyuk Petro , Khomiak Olha , Davydov Oleksander
Published: April 2024

Sylvester's problem or the problem of the smallest bounding circle is the problem of constructing a circle of the smallest radius that contains a finite set of points on the plane. In n-dimensional space, it corresponds to the problem of the smallest bounding hypersphere, which can be formulated as the problem of minimizing a convex piecewise quadratic function.
The article is dedicated to study of the ellipsoid method application for solving this problem and the minimax convex programming problem, which is equivalent to the generalized problem of the smallest bounding hypersphere. The generalized problem consists in finding the center of a sphere in an n-dimensional space that has a minimal radius and contains a finite set of n-dimensional spheres given by their centers and radii.
The article consists of 3 sections. Section 1 describes the emshor algorithm – the algorithm of the ellipsoid method for problem of minimization of an arbitrary convex function, proves its convergence theorems, gives a geometric interpretation of the algorithm, which is based on the use of a minimum volume ellipsoid. Octave implementation of the emshor algorithm is presented here, which can be successfully applied for non-smooth convex functions minimization if the number of variables is n = 2 - 30.
In Section 2, the sylvester1 algorithm is built, which is an application of the emshor algorithm for solving the problem of minimizing a convex piecewise quadratic function, which is equivalent to the problem of finding a sphere of minimum radius for a finite set of points. In Section 3, the sylvester2 algorithm is built, which is an application of the emshor algorithm for solving the problem of minimization of a convex function, which is equivalent to the generalized problem of finding a sphere of minimum radius for a finite set of spheres with given centers and radii. The results of testing the sylvester1 and sylvester2 algorithms demonstrate high working speed for modern computers and high accuracy in terms of optimal value of the objective function when solving problems in n-dimensional spaces for small values n = 2 - 30. Keywords: ellipsoid method, convex function, Sylvester's problem, piecewise smooth function, minimax problem.

Authors:   Korean Society for  Holistic Convergence Education, Kim Pyeong-gook
Published: April 2024

This study explored the process of cognitive coaching in relation to social studies lessons for a low-career elementary teacher. The purpose was to scrutinize the procedures and principles followed by the coach and the teacher and to identify changes in the teacher’s instructional and curricular expertise. During the coaching, the coach utilized mediational tools such as paralanguage, response behaviors, and mediative questioning to facilitate the teacher's self-directed learning process. Consequently, the teacher experienced autonomy in lesson discussions. Reflecting on lesson planning, she recognized the necessity of reading children's books and the need to restructure units. She established goals to enhance her teaching expertise, expressed a willingness to explore self-reflection methods, and hoped to improve her use of mediational tools.
Over a span of 7 months, data were collected from the coach and the teacher. The data collection included pre-coaching open-ended survey responses, transcripts of coaching dialogue over two cycles, and open-ended survey responses from a mid-term evaluation. Additionally, instructional plans for the teacher's 6th-grade social studies class were gathered. These data were analyzed using the constant comparative method, and a validation process was conducted for the results. As recommendations, a paradigm shift focusing on teachers' thinking in lesson discussions, establishing a culture where observers mediate teachers' internal thoughts in a non-judgmental manner, reevaluation of mandatory classroom observations, providing coaching related to individual teachers' lessons within the learning community, concurrent emphasis on personal reflective thinking and sharing and discussing experiences and knowledge within the learning community, fostering collaboration between teacher training institutions and educational authorities for developing and expanding cognitive coaching training programs, and coupling training for the enhancement of instructional expertise and curricular expertise were suggested. Further studies were proposed.

Published: April 2024

This research is a qualitative study of Semi (alias), a gifted Korean male high school student living in urban poverty. Interviews with Semi 6 times for three years, 60 minutes per interview, were analyzed as a part of a longitudinal qualitative study. Semi had been overwhelmed by the harsh environment and unable to move forward. Semi was the only gifted among participants with the highest IQ (in the gifted range with Korea Wechsler Adult Intelligence Scale-Ⅳ at age 17). Although he had the highest intellectual ability among the participants, he did not have confidence in himself. And he did not achieve anything at all when he graduated high school. He spent another year to prepare the college entrance exam, but he failed and left the research for good. The qualitative data were analyed into six themes (neglected childhood, intimate, but worried father, housing instability, helpful teacher, frustrated dream of astronomer, lack of motivation to escape poverty). Among them a representative example of Semi's poor environment is housing instability and Semi's disadvantage is also revealed in that he did not meet an adult who could be a role model for life. The implications and suggestions for future research in career education and counseling were discussed.

This paper presents a theory for the design of informal STEM spaces, aimed particularly at nurturing STEM engagement, creativity, play, and penalty-free ideation among Black boys. It introduces a framework for the intentional creation of open learning STEM environments that enrich Black boys’ experiences within STEM disciplines through cultural STEM mapping. The ILLEST Lab serves as key evidence of effective design implementation, aligning student interests with technical skill enhancement and a sense of belonging in STEM.
I See You: A Photo Album of People with Intellectual Disability
Authors: du Plessis Rory
Published: April 2024

The casebook for the Institute for Imbecile Children, and the casebooks of the Grahamstown Lunatic Asylum constitutes one of South Africa’s largest archived records for people with intellectual disability (PWID) who were institutionalised from 1890 to 1920. In I See You I testify how the viewing of the casebooks’ content and photographs gave rise to a personal recognition of the personhood of the PWID. My testimony takes the form of poetry that is composed to honour and memorialise each individual person who is included in this album.
Creación y Alianza en el Antiguo Testamento a partir de Noé y el acontecimiento del diluvio: una reflexión para el cuidado de la creación
Authors: Villarroel Camila
Published: April 2024

El texto trata sobre la relación entre la Creación y la Alianza en el Antiguo Testamento, centrándose en el relato del diluvio y Noé. Dios crea el mundo con el propósito de establecer una alianza con la humanidad y toda la creación. La historia del diluvio se interpreta como un acto de restauración de esta alianza después de que el pecado corrompiera la naturaleza humana. Partiendo de esas bases, se reconoce la importancia de una consciencia ecológica basada en la relación entre el Creador y la creación, destacando que la alianza con Noé es una alianza universal que incluye a todas las criaturas. Se da una mirada no tan común a este relato en consonancia con la creación y la alianza como un llamado a tomar medidas para abordar la crisis ecológica actual y a asumir la responsabilidad de cuidar y preservar la creación, reconociendo la interconexión de todos los seres vivos en la tierra.

Published: April 2024

Amaç: Hepatit A virüsü (HAV) kendi kendini sınırlayan, akut viral hepatit etkenidir. Dünya geneli viral hepatite bağlı ölümlerin %0,5'inden sorumludur. Ülkemizde endemik olup seroprevalans düşmektedir. Spesifik gruplar ile seroprevalans çalışmaları yapılmakta ve toplum geneli yansıtılamamaktadır. Bu çalışmada hepatit A seroprevalans belirlenerek hepatit A aşılama ihtiyacına ışık tutulması amaçlandı.
Materyal ve Metod : Çalışmaya birinci basamak sağlık kuruluşlarına 1 Ocak 2019 ve 31 Aralık 2022 tarihleri arasında başvuran ve anti-HAV IgG ile anti- HAV IgM testleri istenilen hastalar alındı. İl Halk Sağlığı Laboratuvarı bilgi yönetim sistemi verileri retrospektif olarak değerlendirildi. Tekrarlayan sonuçlar çalışma dışı bırakıldı.
Bulgular: Çalışmada anti- HAV IgM ve anti-HAV IgG düzeylerine bakılan olgu sayıları sırasıyla 128 387 ve 89532, Anti- HAV IgM ve anti-HAV IgG pozitif olgu sayıları ise sırasıyla 233 (‰1.81) ve 79015 (%88.25) idi. Anti- HAV IgM pozitif 233 hastanın 41’i (%17.6) erkek 192’si (%82.4) kadın idi. En sık 25-44 yaş aralığında görüldü. Özellikle 2021 yılı Haziran ve 2022 yılı Mayıs, Haziran, Eylül ve Ekim aylarında ciddi artış fark edildi.
Sonuç: Ülkemizdeki HAV enfeksiyonu azalmakla birlikte halk sağlığı problemdir. İl geneli akut hepatit A prevalansı ‰1.81 olup ülke prevalans verisinin üzerindedir. Çalışmamızda adolesan ve genç erişkin dönemde HAV enfeksiyonunun risk oluşturduğu saptanmış olup özellikle seronegatif erişkinler aşılanmalıdır. Adolesan ve genç erişkin yaş gruplarının rutin aşılama programına dahil edilmesi önerilmektedir.

Cloud computing has revolutionized various sectors, with education standing to benefit significantly. This paper explores the adoption of cloud services among students, facilitated by cloud sponsorships, and its potential impact on training future professionals. Through a comprehensive review of existing literature and case studies, we delve into the intricacies of cloud adoption among students via cloud sponsorships. We discuss the role of these sponsorships in providing students with hands-on experience with state-of-the-art cloud services, thereby equipping them with skills that are increasingly sought after in the job market. Furthermore, we highlight the culture of continuous learning fostered by these programs, crucial in the rapidly evolving field of cloud computing. Our findings suggest that cloud sponsorships play a pivotal role in shaping the workforce of the future, bridging the gap between academia and industry, and contributing to the training of the next generation of working professionals.
