Authors: Assarsson Malin , Söderman Jan , Seifert Oliver
Published: June 2024

Psoriasis results from both genetic predisposition and environmental triggers, such as Streptococcal infections. This study aimed to explore the correlation between the abundance of the Streptococcus genus on the skin and psoriasis severity in individuals carrying specific psoriasis-associated genetic variants. Studying 39 chronic plaque psoriasis patients, the elbow skin microbiome and 49 psoriasis-related single nucleotide polymorphisms (SNPs) were analysed using a MiSeq instrument for 16S rDNA sequencing, and CLC Genomic Workbench for processing and analysis. Through multivariate linear regression analysis, a positive correlation was found between Streptococcus genus abundance and psoriasis severity in patients with certain FBXL19 gene-related heterozygous SNPs (rs12924903, rs10782001, rs12445568). Conversely, a negative association was observed in patients with homozygous genotypes. Moreover, we identified an association between Streptococcus abundance and psoriasis severity in patients with genetic variants related to IL-22, ERAP1, NOS2, and ILF3. This is the first study highlighting a positive association between Streptococcus skin colonization and psoriasis severity in patients with heterozygous genotypes within the FBXL19 gene region. FXBL19 targets the IL-33/IL1RL1 axis, crucial in infectious diseases and innate immunity promotion. These novel results suggests an intricate interaction among host genetics, Streptococcus skin colonization, and psoriasis inflammation, offering potential avenues for novel treatment approaches.

Principle of Islamic Law and Moral Dilemmas of Religious Organisation's Involvement in Mining
Authors: Fanani Ahwan , Budiman Mamdukh
Published: June 2024

This paper aims to bridge the moral dilemmas that arise from government policies granting mining concessions to religious organisations and the role of refligious organisations as social controls on the policy and practice of mining against the moral of law. Moral dilemmas revolve around the risks of involvement, the formation of new oligarchies, economic equity, economic actor diversification, and increased bargaining power for natural resource access. This exploratory study employs the Islamic legal maxim and maqȃṣid shari'a as ethical references. The data, such as legal acts and government regulations, were obtained from the literature. The findings indicate that the real problems of mining and other natural resource exploitation are mismanagement and environmental degradation. Islamic ethics based on the Islamic legal maxim and maqȃṣid shari'a can be used as guidance for civil society organisations to address natural exploitation. However, biocapacity deficit and mismanagement due to overlapping rules and authorities in Indonesia are major obstacles to applying Islamic ethics. This paper suggests that hifẓ bi'ȃh may act as a benchmark for state resource management policies to guide private rights in natural resource management to promote renewable energy industry capacity and ecosystem balance.

Authors:   Lviv Polytechnic National University, Maltsev Eduard , Muliarevych Oleksandr
Published: June 2024

Distributed systems rely on efficient inter-service communication, heavily impacted by data transmission costs. This study investigates alternative serialization formats, like Avro and MessagePack, to reduce data size compared to the common JSON format. We utilize a custom model to comprehensively assess the space efficiency of serialization formats across various data types. Our findings demonstrate that adopting alternative formats achieves a median reduction in serialized data exceeding 30 %. Notably, Avro exhibits exceptional efficiency, leading to reductions exceeding 83 % in specific scenarios. These insights empower developers to select optimal formats, potentially leading to significant improvements in data transfer speed, reduced bandwidth consumption, and enhanced scalability for handling larger data volumes within distributed systems.

Authors:   Lviv Polytechnic National University, Hrynyshyn S. О. , Znak Z. О. ,   Lviv Polytechnic National University
Published: June 2024

The lyophilic properties of pyrocarbon, obtained by pyrolysis of worn automobile tires, in relation to oil, gasoline, benzene, hexane, water, and water-oil and water-gasoline emulsions were studied. The research was carried out by the method of a lying drop on the surface formed by pyrocarbon particles of different dispersion, by determining the contact angle of wetting. The value of this angle was determined by analyzing images obtained photographically. It was established that organic substances and water have a significant contrast in terms of the wetting of pyrocarbon. Based on the determination of the contact angle, the work of adhesion in different systems was calculated depending on the temperature. Based on this, the conclusion was formulated that the selectivity of absorption of oil and oil products will increase with increasing temperature.

Рассмотрены все параметрические зоны словарной статьи, показаны приемы работы в студенческой группе с данными лексикографическими материалами. Результаты итогового контроля показали, что разработанные словарные статьи оказались эффективным средством формирования лингвокраеведческой компетенции корейских студентов. Это подтверждает практическую значимость исследования, материалы которого могут быть использованы на занятиях по русскому языку как иностранному и при составлении учебных словарей пословиц. В научном плане результаты исследования пополняют теоретическую базу кросс-культурного подхода в обучении неродному языку.

The article examines the problem of lexicographical representation of Russian proverbs to Korean students of Russian studies. The concept of an innovative paremiological dictionary is presented, which can be used to develop the linguocultural competence of future teachers of Russian as a foreign language and translators. A special feature of the dictionary is its cross-cultural nature: linguocultural commentary accompanies not only Russian proverbs, but also their Korean equivalents. The principles of material selection are described, all parametric zones of a dictionary entry are considered, and a sample of a complete bilingual lexicographical description of a Russian proverb and its equivalent is given. The methods of working in a student group with each zone of the dictionary entry are shown, and it is indicated which parameters of linguocultural competence this work is aimed at forming. Particular attention is paid to creative tasks, when students, using recommended sources, develop linguocultural comments on Russian and Korean proverbs. The data from the final control showed that the experimental work carried out with lexicographic materials turned out to be an effective means of developing the linguistic competence of Korean students, increasing interest in paremiology and motivation to study the Russian language and culture. This confirms the practical significance of the study, the materials of which can be used in classes on Russian as a foreign language and in the compilation of educational dictionaries of proverbs. In scientific terms, the research results presented in the article complement the theoretical basis of the cross-cultural approach to teaching a non-native language.
“Once Again, From the Beginning:” Re-inventing the Museum Library at the University of Pennsylvania
Authors: Stewart Deborah
Published: June 2024

As university museums and academic programs struggle with issues of relevancy and harmful legacies, the libraries that are embedded within these institutions must reckon with similar challenging issues because of their own histories, collections content, museum-adjacent programs, and assumed authority in the supported disciplines. Such departmental libraries already occupy uncomfortable positions within complex institutions, often functioning as minor players in the university’s library systems, but only tenuously linked through location or subject matter expertise to the university’s museums and affiliated departments.
Offered as an instructive example is the Museum Library at the University of Pennsylvania, affiliated with the sometimes embattled Penn Museum. This “Report from the Field” essay describes the Museum Library’s methods for participating in a rapidly evolving museum’s strategic initiatives and supporting the sincere investment of its dedicated staff in making meaningful changes. I also discuss the Museum Library’s own complicated history and our reflections as we remake the library in the face of local and global challenges.

Authors: Stillwell Joana
Published: June 2024

Typically, museums are seen as the primary venue for exhibitions. However, an interest in library exhibitions has been growing as indicated by increased literature in the library field, albeit with a large focus on academic libraries. On a broader scale, library exhibitions continue to be under-researched as indicated by the continuing lack of library exhibition evaluation standards, library exhibition reviews, and exhibition-related professional training for librarians. In this 2021 study, interviews were conducted at eight Washington, DC-based art museum libraries: The National Gallery of Art, The National Museum of Women in the Arts, The American Art and Portrait Gallery, The Freer Gallery of Art and Arthur M. Sackler Gallery, The Hirshhorn Museum and Sculpture Garden, The National Museum of African Art, The Phillips Collection, and the George Washington University Textile Museum. This paper is an examination of the current state of exhibitions in art museum libraries and aims to establish a set of best practices to help foster the production of art museum library exhibitions.

Authors: Huuskonen Arto Kalevi , Pesonen Maiju , Manni Katariina
Published: June 2024

Total mixed rations (TMR) based on red clover silage (RS), whole-crop barley silage (BS) and mixture of RS and BS were fed to thirty Hereford (HF) and thirty Simmental (SI) bulls. The proportion (g kg-1 dry matter (DM)) of the silages in the TMRs were as follows: (1) RS (600); (2) BS (600); (3) RS (300) and BS (300). Concentrate proportion was 400 g kg-1 DM. Breed × feeding interactions were observed for intake parameters. Replacing RS by BS tended to increase DM and nutrient intake more in the SI compared to the HF breed. For growth performance a significant quadratic effect was observed for the dietary treatments; both the live weight gain and carcass gain were the highest when RS was partially replaced by BS. There were no differences in carcass weight, dressing proportion or carcass conformation among the dietary treatments. However, replacing RS by BS increased carcass fatness. The SI bulls had higher growth rate and they produced better conformed carcasses and less fat compared to the HF bulls.

Flexible approaches to the implementation of marketing strategies of organizations
Authors: Semibratskiy Maxim  Viktorovich
Published: June 2024

Traditional views on the processes of developing and implementing marketing strategies do not allow us to fully take into account the influence of the external environment and, as a result, make marketing strategizing procedures less effective. A possible solution to ensure greater effectiveness of the latter may be the adaptation of flexible management practices and the implementation of marketing strategies in a flexible and iterative manner. The process of testing marketing hypotheses in the logic of the HADI cycle is illustrated. The features of an adaptive approach to the implementation of long-term plans are considered, the author's view on the use of agile principles in strategic marketing management is presented. Compliance with such principles can improve the effectiveness of strategic marketing decisions through better analysis of the external environment and constant updating of marketing plans. The approach to the implementation of strategies is considered as dynamic. An example of planning by a business school to develop and market a new professional retraining program in order to increase revenue growth from the provision of paid educational services is given. The main tasks and stages of implementing a flexible marketing strategy in scrum logic are highlighted. It is noted that during the final retrospective, the experience is systematized and internal formal and informal rules are being formed for future projects to create educational products. An iterative algorithm for the implementation, analysis and updating of marketing strategy activities in scrum logic is schematically presented.
State property management: problems and analysis of the current situation
Authors: Danilova Ol'ga Viktorovna , Belyaeva Irina Yur'evna
Published: June 2024

The article examines the transformation and trends in the development of state property institutions in Russia, starting from the privatization of state assets in the 1990s of the last century to the present. The importance of the transition from state to joint-stock and private ownership from the position of choosing optimal forms of ownership in the formation of effective market mechanisms is noted. The specific and distinctive features of the development of property relations in the Russian Federation, the factors influencing the renewal of property institutions and changes in the management system of the state property are identified, since property forms the basis of all economic systems, is a basic economic relationship, has many properties, parameters and qualities, and each new form of ownership creates new public institutions. Conceptual approaches to the content of property and models of state property management in accordance with the tasks to be solved are investigated. The author's interpretation of methodological approaches to the formation of a mechanism for managing state property is presented, which is based on the cyclical development of property relations and the need for an optimal combination of ownership forms. The State, recognizing the expediency of switching to the use of market instruments in property management, in practice monitors the effective and targeted use of problematic, strategically important industrial assets that ensure the country's defense capability. It is concluded that in the context of modern changes in global management systems, there is an interconnected modification of both property relations and corporate relations. The ongoing processes are the result of changes in the internal and external business environment, organically included in the overall picture of global socio-economic transformations. It is noted that state assets transferred to private ownership are not managed efficiently enough. A well-organized mechanism for managing state property will allow us to build a pragmatic balance between market instruments and maintaining the levers of state influence on the development of all sectors of the national economy

A new fractional integral operator is used to present a generalized class of analytic functions in a complex domain. The method of definition is based on a Hadamard product of analytic function, which is called convolution product. Then we formulate a convolution integral operator acting on the sub-class of normalized analytic functions. Consequently, we investigate the suggested convolution operator geometrically. Differential subordination inequalities, taking the starlike formula are given. Some consequences of well-known results are illustrated.

Kota Pariaman terdiri dari 4 kecamatan , 16 kelurahan dan 55 des. Luas wilayahnya mencapai 66,13 km dan penduduk 88.984 jiwa. Secara astronomis, Kota Pariaman terletak antara 00° 33‘ 00 “ – 00° 40‘ 43“  Lintang Selatan dan 100° 04‘ 46“ – 100° 10‘ 55“ Bujur Timur. Tercatat memiliki luas wilayah 73,36 km2, dengan panjang garis pantai 12,00 km. Luas daratan kota ini setara dengan 0,17% dari luas daratan wilayah Provinsi Sumatera Barat, salah satu ciri dari desa pesisir adalah aktivitas dan hubungan antara sistem alamiah (sumberdaya) dan manusia (sosial ekonomi). Sistem sosial ekologi (SES) atau sistem sosial ekologi (SES) adalah istilah yang lebih umum digunakan untuk menggambarkan desa pesisir. Pada Penelitian ini penulis menggunakan metode pengamatan secara langsung dengan pengambilan data primer berupa observasi partisipasi aktif, wawancara, dokumentasi dan data sekunder yang diperoleh peneliti dari literatur yang sudah ada melalui media perantara, seperti buku dan jurnal, secara langsung dan tidak langsung. Hasil penelitian bertujuan untuk mengidentifikasi bagaimana sistem sosial ekologi pada taman Wisata hutan Mangrove kota Pariaman. Hutan Mangrove di Desa Apar merupakan salah satu destinasi wisata populer di Pariaman, menghadapi tantangan karena terbatasnya pemahaman dan pengelolaan, sehingga menyebabkan deforestasi. Peran dari beberapa stakeholder dan Badan Usaha Milik Desa (BUMDes) Apar Mandiri Wisata ini meningkatkan ekonomi masyarakat dengan adanya destinasi wisata yang menarik kunjungan wisatawan, serta dapat menciptakan lapangan perkerjaan baru, dan peningkatan pendapatan masyarakat di sekitar lokasi tersebut sehingga aktivitas yang dilakukan manusia menjadi jembatan sistem sosial ekologi yang bebas terhubung dengan sistem sosial.

Purpose: This work aimed to conduct chemical characterization, assess antioxidant activity, and quantify phenolic compounds in Amazonian Robusta Coffee beverages prepared using diverse roasting degrees and extraction methods.
 
Theoretical Framework: Coffee is globally consumed and holds substantial importance as a commodity. Its chemical composition and biological activity of coffee are influenced by several factors, such as cultivar, roasting degree and brewing method.
 
Methods: Amazonian Robusta Coffee beverages were prepared using diverse roasting degrees and extraction methods (Hario V60, French press and Cold Brew). Characterization was conducted to physicochemical analysis (color parameters, browning index, pH, Brix and total dissolved solids), total phenolic compounds (Folin-Ciocalteu method) and antioxidant activity (FRAP, DPPH, ABTS+ and ORAC assays).
 
Results and Conclusions: Hario V60 beverage demonstrated the highest levels of total phenolic compounds (+50%) and antioxidant activity (+40%) across all roast levels (p<0.01), with significantly increased concentrations of total dissolved solids and phenolic compounds compared to French Press and Cold Brew. This enhanced extraction efficiency is likely due to greater surface area exposure and the percolation method. In contrast, Cold Brew exhibited higher a*, b* and Browning Index values (p<0.05), indicating more intense colors from prolonged extraction and greater melanoidin solubilization.
 
Research Implications: This work showed the chemical composition and antioxidant activity of Amazonian Robusta coffee beverages and their potential application for sustainable production.
 
Originality/Value: No previous study has assessed the antioxidant potential, phenolic content and physicochemical characterization of Amazonian Robusta coffee beverages.

OBJECTIVE. To investigate the efficacy of extracorporeal shockwave lithotripsy (ESWL) and ureteroscopic laser lithotripsy (URS) treatment of upper ureteric stones between 10 to 20 mm in size. From January 2020 to January 2023, 75 patients were treated for proximal ureteric calculus between using ESWL (n=40) & URS (n=35).

METHODS AND MATERIALS. Both groups were compared regarding operative time, success rate and complications who underwent treatment for proximal ureteric calculus of 10–20 mm in diameter. URS group was observed to have higher stone-free rate, compared to the ESWL group, 31 (88.6 %) vs 20 patients (50.0 %) (p<0.001).

RESULTS. URS treatment had a higher complication rate compared to the ESWL, 9 (25.7 %) vs 3(7.5 %) ;( p=0.032). Procedure time for URS was longer, compared to the ESWL, median (IQR) for URS vs ESWL were 78.0 (65.0, 100.0) vs 62.0 (48.0, 67.0) minutes; (p<0.001).

CONCLUSION. We conclude that URS has a better stone-free rate in comparison to a single session of ESWL for upper ureteral calculus of 10–20 mm, with higher complication rates such as post-operative fever and pain.

Penetrating abdominal wounds occupy a significant place in the structure of gunshot injuries in peacetime and war. They are usually characterized by extensive multiorgan damage with the development of peritonitis, the course of which largely determines the outcome of treatment. Therefore, the main task in providing specialized surgical care for victims with gunshot abdominal wounds is to relieve peritonitis in order to prevent the generalization of the septic process. One of the modern trends in solving this problem is vacuum-assisted laparostomy. However, data on its use are presented in rare publications and are usually based on small samples of patients with secondary peritonitis. At the same time, we did not find any information in the available sources about the effectiveness of the most promising modification of this technique – vacuum-instillation laparostomy for gunshot abdominal wounds. This article demonstrates the first experience of the successful use of vacuum-instillation laparostomy in a patient with gunshot abdominal wound complicated by abdominal sepsis. The obtained results indicate the high potential of using this technique in this difficult category of patients.
