Introduction to the Special issue: The sum of its parts, what a platform of digital humanities courses says about digital humanities
Authors: Kamal Ahmad M.
Published: April 2023

This paper discusses a newly created platform of online courses covering a range of digital humanities methods and asks what the assortment of courses demonstrate about the nature of digital humanities (DH). The role of methods in defining the field of “digital humanities” is reviewed, followed by description of the educational platform itself – Digital Methods Platform for Arts and Humanities (DiMPAH) – before reflecting on what the ensemble of courses reveal about digital humanities in practice. Themes emerging from this reflection include: the division between research-driven and collection-driven initiative; the situatedness of methods; and the persistent role of disciplinary knowledge matters. The paper concludes by what the platform – produced by scholars from across Europe – along with the methods and use cases presented therein suggest about future stories for the continent through DH.

One of the major challenges in deep space exploration are effects of cosmic rays on human body and soft error, but equally important are their effects on food resources. In this study, we focused on neutrons as the secondary particle in the deep space environment and investigated how they affect food resources. Fast neutron was irradiated by the RIKEN Accelerator-driven compact Neutron Source (RANS) on meat sample. Biochemical analysis was conducted to present concrete effects of cosmic rays on food in deep space environment. Oxidative and nitrative modifications of proteins were detected by the electrophoresis and Western blotting. The result shows that nitrative modification of tryptophan, which is an essential amino acid in protein, tended to increase with increasing neutron dose.

CONCLUSION: Supporting employment consultants with data-enabled feedback is key for improving the quality of supported and customized employment services, a key step toward improving job seekers’ employment outcomes.
The Impact of Coastal Regulation Zone Legislation on City Development: A Study with Reference to Mumbai
Authors: Nallathiga Ramakrishna , Jadhav Suyog , Mane Tejashri , Lohar Aniket
Published: April 2023

The Coastal Regulation Zone (CRZ) legislation was brought in India in order to curb environmentally detrimental activities along the coastline. It is one of the controversial legislations in the country, which affected the development of cities and their infrastructure. For topographically constrained land-scarce cities like Mumbai, which also faces the challenge of a growing population and economic activities, the CRZ legislation turns out to be a bane for development. The city already has a large amount of population living in informal housing (slum and squatted settlements) due to the limited availability of land. The CRZ legislation would further limit the land available for development in Mumbai and, thereby, affect infrastructure, development, and property prices. This article examines whether the CRZ legislation would have impacted the coastal city of Mumbai in the form of informal development, lower infrastructure availability, and dampened property prices by making use of ward-level data. The study examines multiple, sequential, and interlinked hypotheses to assess how the CRZ legislation would have affected the development outcomes in the city. The results are assertive of the broader impact of CRZ legislation on the rise of informality, lower infrastructure availability, and poorer property prices. The study results are suggestive of the need to avoid a blanket approach towards coastal regulation; rather, it requires careful consideration of the local context of cities along the coastline and consultation with local government. However, the results have to be viewed from the perspective of Mumbai city and also in the light of limited data of a few wards along the Mumbai coast, which we use to arrive at the conclusions.

Published: April 2023

BACKGROUND: Jingshen Xiaoke decoction (JS) was prepared by studying the classic prescriptions of famous scholars in the past dynasties to prevent and treat diabetes. The related mechanism of JS against hyperlipidemia has yet to be revealed. OBJECTIVE: To investigate the mechanism of action of JS in treating diabetes mellitus by using bioinformatics methods. METHODS: A database was used to search the active ingredients and targets of the JS and targets for type 2 diabetes mellitus (T2DM). The protein interaction between the intersection targets, and the constructed the PPI network diagram was analyzed using the STRING database. Furthermore, the gene annotation tool DAVID was used to enrich the intersecting targets for the Gene ontology (GO) function and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathway. Finally, Maestro software was used for molecular docking to verify the binding ability of the active ingredients to the core target genes. RESULTS: A total of 45 active ingredients in JS were screened out corresponding to 239 effective targets, of which 64 targets were potential targets for treating T2DM. The analysis of PPI network diagram analysis revealed that the ingredients’ active components are quercetin, β-sitosterol, stigmasterol, luteolin, and 7-Methoxy-2-methyl isoflavone. GO functional enrichment analysis indicated 186 biological processes (BP), 23 molecular functions (MF) and 13 cellular components (CC). KEGG pathway enrichment analysis revealed the enrichment of 59 signal pathways. The molecular docking results demonstrated that the active ingredients and core targets had a good docking affinity with a binding activity less than -7 kcal/mol. Finally, the western blotting illustrated that JS could up-regulate the liver PI3K/AKT-signaling pathway. CONCLUSION: JS can regulate glucolipid metabolism, reduce the inflammatory response, improve insulin resistance and modulate the immune response through PI3K/AKT signaling pathway treating of T2DM and its complications effects.

Published: April 2023

BACKGROUND: Assessment of maximal oxygen consumption is important in both general community and occupational settings. Validity and reliability tests are needed to indicate the functionality of the cardiopulmonary system. OBJECTIVE: This study aimed to establish a maximal oxygen consumption (VO2max) prediction model using anthropometric and demographic variables for young adults in Iran. METHODS: This cross-sectional study was conducted on 64 healthy young men aged 19–29 years. Oxygen consumption was measured directly and the prediction models to estimate VO2max were determined by multiple linear regression. The accuracy of the prediction models was considered using regression coefficient (R), coefficient of determination (R2), and standard error of estimate (SEE). RESULTS: The average VO2max was 44.02±4.31 ml/kg/min. Significant correlations were found between the measured VO2max and the anthropometric and demographic variables (r = 0.16–0.86, P < 0.05). Three significant regression models with acceptable accuracy were developed (R2 = 0.67–0.71, SEE = 3.19–3.21). CONCLUSION: The predictive models consisted of 3–5 variables as significant predictors of VO2max and had acceptable accuracy for Iranian young adults. The proposed models are a simple and valid tool that can be used to estimate the VO2max in the field and in laboratory settings.
“Is this a new dawn for accessibility?” A qualitative interview study assessing remote working experiences in adults with physical disabilities post COVID-19
Authors: Lake Betsy , Maidment David W.
Published: April 2023

BACKGROUND: While employers plan how to restructure working practices after the initial response to the COVID-19 pandemic, it is essential that the disability community are represented in research addressing remote working (or telework); their expertise is invaluable for ensuring equity from the outset. OBJECTIVE: The current study qualitatively investigated how people with physical disabilities negotiate telework in a post-COVID era. METHODS: Ten participants with a range of physical disabilities were recruited and interviewed. Themes were generated from the data utilising an established method of reflexive inductive thematic analysis. RESULTS: Increased flexibility as well as control over work schedules and the environment facilitated by teleworking, improved participants’ disability management, health, work performance, and personal opportunities. However, the importance of choice to work in-office, of implementing additional physical and virtual work adjustments, and of flexible work patterns to remove barriers to accessibility when homeworking was emphasised. Active efforts by employers to create an inclusive and flexible work culture were identified as crucial to ensure that integration and professional development of employees with disabilities, understanding of disability experience, and normalisation of accessibility needs are not diminished by the decreased visibility incurred by teleworking. CONCLUSION: Teleworking is not a panacea for resolving the disability employment disadvantage. Rather, teleworking could be a springboard upon which further flexibility and choice can be built to shift organisational practices to better accommodate individual employees, with and without disabilities, post-COVID. It is imperative to act on such insights to create accessible workplaces to facilitate more inclusive workforces.
Artificial islands as system-forming elements of the urban structure
Authors: Ladigina Irina , Rudenko Alina
Published: April 2023

Artificial islands are considered as anthropogenic landscapes that have a rather long history of their formation in the structure of human settlements, starting from the Neolithic.
The dynamics of their functional enrichment, starting from the agricultural function to the transformation into complex multifunctional urban-type structures in the conditions of the modern stage of the urbanization process, are analyzed.
The main materials and technologies used to create artificial islands in different countries were studied.
The world experience of the formation of artificial islands and their use as system-forming elements of the functional and planning organization of urban settlements with the aim of its improvement, compensation of certain functions, and solving the problem of the lack of territorial resources has been studied.
Emphasis is placed on the features of the formation of artificial islands of the new generation, which arise at the junction of technological eras and are huge rural formations that increase tourist flows by creating global recreation and entertainment centers, cover tens of kilometers with hundreds of people and are included in the existing settlement system as new system-forming elements.
Certain problems have been identified that, despite all the uniqueness of ideas, the availability of the latest technologies and materials, arise when creating artificial islands - a very large estimate; the probability of a negative impact on the environment and ecological unpredictability of the prospective state of their anthropogenic landscapes; lack of experience regarding longevity of existence and operation.

Authors: Spasichenko Kateryna
Published: April 2023

The importance of creating high-quality housing units with affordable housing in the resettlement system is highlighted. Some examples of affordable housing in world practice are analyzed. The importance of the location of a residential unit with affordable housing on the quality of living in it and on some characteristics of such housing, such as price and number of floors, is described.

A number of authors who studied the formation of the urban environment and their problems are cited.

The article proposes several universal models of residential formation with affordable housing for a large city (model of residential formation with affordable housing in the structure of a residential group) and for a small settlement (model of residential formation of blocked buildings), which are based on the principles of multi-comfort and sustainable development, taking into account the development in time.

The main areas of residential formation have been determined. The need for integration of different types of housing in the residential formation is indicated, such as: commercial housing of various comforts, affordable housing, social housing, rental housing, affordable rental housing. The importance of determining the appropriate percentage of integration of different typologies of housing is highlighted, and its schematic marking on general plans of territories is proposed.

The necessity of designing a residential building with the integration of public service premises and places of employment is indicated. Insert blocks with public, communication and social significance in a residential structure for block or individual construction in small settlements are proposed.

A number of important tasks that must be solved by the development of urban planning documentation (establishing the territories or plots of the location of affordable housing; the planned percentage of such housing in a district, quarter or building; determining the required number and calculation of types of apartments, etc.) are given.
Analysis and classification of modern constructions of large span coverings of buildings
Authors: Getun Galyna , Bezklubenko Iryna , Solomin Andrey
Published: April 2023

The impetus for the search for new forms of buildings and structures and the development of a new understanding of space was the emergence of new types of structures and related construction technologies. Technical and economic calculations show that the area of coverings in buildings with large hall rooms, as a rule, exceeds the total area of other enclosing structures, and therefore the cost of coverings, taking into account installation work, is of predominant importance in construction estimates. Spatial forms of coverings of hall rooms significantly affect the architectural expressiveness of buildings, and therefore the issue of choosing forms, materials and rational constructive solutions of coverings is extremely relevant. The article analyzes the types of long-span coatings, their classification, the conditions of use as load-bearing structures of building coatings, as well as some problems of their static operation, which are related to the choice of form and conditions of their support and division into structural elements. The most important components of the covering systems of buildings and structures are supporting structures, which have unlimited possibilities of interpretation of forms and materials, can be hidden or open and turn into architectural elements. It is obvious that in the process of designing the coverings of buildings and structures, it is necessary to consider and analyze various options for their constructive solutions. The authors considered the problems of calculations and construction of coatings, choosing their rational forms, which ensure the prevention of loss of their stability from the bending plane and a high aesthetic level. The main principles and methods of construction and static calculation of coatings and conditions of their application are given.

Authors: Oliynyk Olena , Tokar Mariia
Published: April 2023

The article examines the principles of sustainable development, which dictate new approaches and tools for the design of modern multifunctional family leisure centers in the conditions of a metropolis. The study is aimed at determining the approaches and principles that must be used in the modern architecture of family leisure centers in order to meet global demand and the requirements of sustainable development, which are guided by the UN and other world public organizations. The use of ecological and energy-saving means in the process of designing multifunctional family leisure centers, aimed at achieving the durability of buildings, reducing operating costs, reducing the cost of construction, influencing the awareness of the population about reducing the level of pollution, is based on ecological principles and careful management of natural resources and autonomy.
The new challenges of time and the high rhythm of life in cities require in the future an increase in the quality and number of recreation places, facilities for recovery and spending time together, namely multifunctional family leisure centers. Meanwhile, high standards and requirements for the design and architecture of new buildings, dictated by the principles of sustainable development, require new design, engineering, innovative solutions and approaches. The world began to change more rapidly in the last 30 years, and its population must quickly adapt to new conditions. At the same time, there are some things that do not change or change very little: the insolation of the sun, the speed of the wind, the physical characteristics of concrete and metal, and others.
Thus, architects can create buildings and projects using modern technologies, principles and tools of sustainable development, and as a result, these projects can be durable and can be called sustainable. There are many systems for assessing the sustainability of buildings around the world. In addition to the US Green Building Council, which administers the Leadership in Energy and Environmental Efficiency (LEED) system, there are other rating systems that have been developed to measure the level of sustainability of buildings and provide best practice experiences with the highest level of certification.

Authors: Bulhakova Daria , Kozakova Olena
Published: April 2023

The article highlights the relevance of the problem of the ecology of our time. When posing the problem, the main aspects that lead to the current difficulties with ecology are determined. The main problems that are already facing us because of climate change are indicated. The problem of using plastic, which fills most landfills with waste, is also considered. Based on these problems, it is proposed to determine the happiest countries in the world according to a rating compiled by independent contractors at the request of the UN. In this way, the main problems of the countries are deduced and summarized in comparative statistics based on unifying problems. The existing methods and technologies currently promoted by the world's leading countries in comparison with our country are also considered. Despite the fact that countries differ in geographical location, level of development, availability of natural resources, and other factors, they all face environmental problems. Climate change - global warming due to CO2 emissions - is one of the most common problems. The level of global warming of 1.5°C may soon be crossed, unless rapid and large-scale reductions in greenhouse gas emissions are made, we are doomed to global climate change in every region

The world suffers from global climate changes, social segregation, lack of full implementation of recycling technologies, recycling of human life items, epidemics, financial crises, etc. Ukraine, before the above list, has been on the permanent fire for quite a long time. Despite the indescribable depth of the tragedy that Ukraine and Ukrainians are experiencing every day, we have the opportunity to create a completely new country, implement the best achievements, and most importantly, logically implement them in the local context, and not blindly copy them. The World Bank report published in its study a list of directions that the global community should pay attention to and take into account in its various developments.

For Ukraine, the problems of eco-genocide, which are caused by hostilities on the part of Russia, are indicated and potential methods of their solution are considered.
Features of art synthesis in architecture and design
Authors: Zhovkva Olha
Published: April 2023

The article makes a brief excursion into the history of the development and formation of various types of art such as painting and sculpture from the time of Ancient Egypt. The question of the canon in sculpture and painting is considered. It also reveals the main features and methods of using the synthesis of arts (painting, sculpture, stained glass, artistic ceramics, etc.) in the formation of modern interior space in residential and public architecture. The formation of the interior space of objects of architecture by means of art tools in the broad sense of the word is dealt with. A brief analysis of the state of contemporary art and ways of further development is performed. The particularities of interaction between the architecture and works of art are defined and possible ways of integration are outlined. Today, when designing public and residential buildings and their spaces, it is necessary to think about the issues of environmental friendliness and energy efficiency, thus contributing to the improvement of the ecological situation. The trend of "Environmentalism" in architecture and design can be manifested through the use of ecological materials in the construction and furnishing of interior spaces. In view of the above, it should be noted that the synthesis of arts can be a powerful and useful tool in the hands of both architects and designers when solving the issue of furnishing the internal and external space of buildings and structures with different purposes, as well as being a means of achieving their artistic and architectural goals. expressiveness.
Black color in architecture - traditions, modernity and perspectives
Authors: Toporkov Volodymyr
Published: April 2023

The color of the facades of urban buildings directly shapes the aesthetic qualities of the architectural environment. The trend of increasing the number of houses with black facades in the future may lead to the transformation of cities with their characteristic color into huge black burial complexes. Therefore, the concept of "black color" in architecture is quite blurred, not clear. However, you can still try to select buildings whose facades are so dark that they can be considered black, but with different shades. In the future, we will conventionally combine such buildings into a group of buildings with black facades. However, black facades have their own specifics, the failure of which significantly reduces the aesthetic qualities of the building. In Figure 13, you can see how much the black color suppresses the plasticity of the facade and the chiaroscuro formed under the influence of sunlight. Even the huge cantilever overhangs of the upper floors cannot create the effect of depth on the architectural form. Bright sunlight cannot destroy the deafness and darkness that blackness creates. The black facades of skyscrapers definitely make a strong impression with their size, even though the facade plastic on them is barely visible. Perhaps for this reason, large black buildings often have a simple geometry, where the shape of the general outline, the outline of the house visually works more effectively than the division within the shape itself. Black color reflects light so poorly that even simple geometric shapes of skyscrapers look flat, not three-dimensional. In such conditions, it becomes urgent to search for options for dividing the facades, which would reveal and emphasize the three-dimensionality of the object (Fig. 16).
The aesthetics of black facades has its positive and negative sides. Black buildings bring an element of contrast and a certain drama to the multi-colored buildings of large cities, and therefore their construction will continue. However, the strong leveling, and sometimes complete, of the plastic characteristics of the building with the black color of the facade leads to the architecture losing its fundamental properties - three-dimensionality and spaciousness. The organization of the form, architectural details, proportions, all this becomes unnecessary, superfluous - because it will not be visible anyway. Added to this is the psychological impact of black color on a person, especially on a large scale, when black color becomes a dominant factor in the formation of color characteristics of the urban environment. In the current conditions, architects should carefully and sensibly use black color in buildings.
Features of Language Policy in Soviet Ukraine: Socio-communicational Aspect (1960s–1980s)
Authors: Sichkarenko Halyna
Published: April 2023

The purpose of the article is to examine the controversial aspects of language policy in Soviet Ukraine in the 1960s-1980s through the prism of the socio-communicational approach. The research methodology is based on the use of general scientific and special methods of cognition, in particular, periodisation, historical and comparative, typological, statistical methods, as well as a combination of the principles of scientific objectivity and systematicity. Scientific novelty. The article clarifies the features and content of the stages of language policy in the 1960s-1980s in Soviet Ukraine. Separately, on the basis of archival documents, it has been shown that in the second half of the 1980s, under the influence of the processes of “perestroika” and the speeches of the Ukrainian public, the national language policy in the republic changed towards the spread of the use of the Ukrainian language in social communication space, which led to the adoption of the Law “On Languages in the Ukrainian SSR” in 1989. Conclusions. The article shows that the language policy in the Ukrainian SSR in the 1960s-1980s was somewhat ambiguous, which was determined by the ideological line of the CPSU Central Committee. Thus, in the 1960s, there was a departure from the despotic policy of the Stalinist period and a decade of Khrushchev's thaw. During the 1970s and first half of the 1980s, anti-Ukrainian measures based on Russification were launched with renewed vigour. Russian became the language of everyday communication for the majority of the urban population, with the exception of the western regions. From the second half of the 1980s, during the unfolding of the policy of “perestroika” and active public protests against the background of glasnost, certain democratisation and economic reform, the use of the Ukrainian language in state institutions became widespread. In 1989, the Law “On Languages in the Ukrainian SSR” was adopted and remained in force until 2012. Further research is needed into the factors of the spread of the Russian language in different regions of the Ukrainian SSR, as well as the motivation of the population to perceive this process.
Key words: Ukrainian language; language policy; Russification; Ukrainian SSR; Soviet power.

Superheater adalah salah satu komponen boiler yang berfungsi untuk memanaskan uap jenuh yang keluar dari steam drum, material yang sering digunakan pada superheater adalah SA-213 grade T91 dan SA-213 grade T22, pada penelitian ini menggunakan proses pengelasan Gas Tungsten Arc Welding (GTAW). Kedua material yang digunakan wajib dilakukan proses PWHT, karena salah satu tujuan PWHT adalah menurunkan nilai kekerasan dan menyeragamkan struktur mikro. Penelitian ini bertujuan untuk mengetahui perbandingan PWHT dan tanpa PWHT pada material SA-213 grade T91 dan SA-213 grade T22 terhadap struktur mikro dan kekerasan. Hasil pengujian struktur mikro menunjukkan adanya pengurangan prosentase pearlite serta martensite dan adanya penambahan ukuran butir struktur mikro setelah PWHT. Pengujian hardness vickers menunjukkan adanya penurunan nilai kekerasan yang signifikan, khususnya pada daerah weld metal dan HAZ antara material tanpa PWHT dan PWHT. Didapatkan nilai kekerasan tertinggi pada weld metal SA-213 grade T91 tanpa PWHT dengan nilai kekerasan 376.70 HVN dan nilai terendah weld metal ada pada spesimen dengan holding time 45 menit yaitu sebesar 201.1 HVN.

This qualitative study examined rural educational leaders’ perceptions of the outcomes of the 2019 Leadership Camps (LCs). This capacity-building opportunity helped educational leaders meet as a community of practice (CoP) where participants’ interactions contributed to learning with and from one another, reducing perceived isolation and increasing self-efficacy. We analyzed data collected from 242 participants’ responses using an open, axial, and selective coding process. With this sample, 52.5% of participants were rural educational leaders. Overall, educational leaders most often appreciated interacting, networking, and collaborating with peers. Additionally, educational leaders highlighted the importance of the in-depth understanding and application of the Leadership Standards and reflective practices. We claim that this approach to professional development within a CoP offers rural educational leaders various work-related growth opportunities, including fostering collaboration, promoting professional conversations, and creating a community for reduced isolation, which will likely enhance their job performance and satisfaction.
ВИРІШЕННЯ СОЦІАЛЬНО-ТРУДОВИХ КОНФЛІКТІВ НА ЗАСАДАХ ПАРТНЕРСТВА ТА СОЦІАЛЬНОЇ ВІДПОВІДАЛЬНОСТІ

У статті розглядаються актуальні питання дослідження та вирішення соціально-трудових конфліктів на засадах діалогу та соціальної відповідальності, що ідентично самій філософії та ідеології соціального партнерства, узгоджується з кращою світовою практикою консолідованого розв’язання протиріч у соціально-трудовій сфері. Розглянуто конструкт соціально-трудового конфлікту як багатоаспектного феномену суспільної життєдіяльності. Аргументовано потенціал соціального діалогу як інституту узгодження неспівпадаючих інтересів сторін і суб’єктів соціально-трудових відносин та опрацювання взаємних зобов’язань. Підтверджено гіпотезу, що соціальне партнерство може і повинне поставати платформою, організаційним механізмом та соціальним інститутом посилення індивідуальної відповідальності суб’єктів відносин у сфері праці, інтеграції останньої в якісно нову – спільну, загальну, консолідовану відповідальність.

Актуальність статті полягає в тому, що Національна поліція України є одним із ключових правоохоронних органів нашої держави, який в процесі здійснення своєї діяльності виконує низку складних суспільно важливих завдань. Поліцейська діяльність та механізми забезпечення її представників сьогодні є одними з найактуальніших питань юридичної науки. Вчені знаходяться у постійному пошуку шляхів удосконалення правових засад функціонування поліції та забезпечення більшої ефективності діяльності Національна поліція України. Одним з аспектів, що перебуває в полі зору науковців, є медичне обслуговування поліцейських. У статті, спираючись на аналіз наукових поглядів вчених та норм чинного законодавства, запропоновано авторське визначення поняття медичного обслуговування членів сімей поліцейських. Виокремлено та охарактеризовано особливості медичного обслуговування членів сімей поліцейських у порівнянні з іншими категоріями працівників. Виокремлено та охарактеризовано ключові аспекти, які розкривають сутність медичного обслуговування членів сімей поліцейських, як важливої гарантії їх соціального забезпечення. Зроблено висновок, що медичне обслуговування членів сімей поліцейських – це діяльність із надання лікувальних, реабілітаційних, санітарно-курортних та інших видів медичних послуг членам сімей поліцейських з метою охорони та поліпшення їх здоров’я спеціалізованими закладами охорони здоров’я Міністерства внутрішніх справ України у порядку, визначеному відомчим законодавством, норми якого спрямовані на регулювання роботи Національна поліція України взагалі, та її службовців, зокрема. Як важлива гарантія соціального забезпечення, медичне обслуговування членів сімей поліцейських характеризується такими ознаками: забезпечується конституційними нормами та механізмами державного фінансування на рівні із іншими секторами медичної галузі України в цілому; регулюється нормами спеціалізованого законодавчого акту Законом України «Про Національну поліцію»; порядок реалізації відповідних послуг формується не органами влади в сфері управління медичною галуззю, а Міністерством внутрішніх справ України; здійснюється спеціальними закладами охорони здоров’я, які відносяться до відання МВС, що мають особливий адміністративно-правовий статус.
