Published: July 2022

This paper presents the experimental investigation of full-scale precast concrete beam-column connections subjected to cyclic lateral loading. The specimen consists of three models. Two of which are precast beam-column connections and one is monolith. The precast and monolith specimen were designed for the same strength. The cross-sectional dimensions of the beam 250 mm x 300 mm and column 300 mm x 300 mm. Connections are placed in plastic hinge area, with a distance of h (beam height) from the face of the column which is expected to occur first destruction.  Precast construction joints are distinguished, with 3 different models, namely monolith, double notch type 1 (STR-1), and double notch type 2 (STR-2). Maximum load capacity, hysterical behavior and energy dissipation are measured, and capacity is compared. The results showed that beam-column joint    STR-2 are better able to absorb energy than beam column joint monolith and beam-column joint STR-1. Kumulative energy dissipation of monolith about 9333.07 kN-mm, STR-1 is 8336.76 kN-mm, and STR-2 is 10162.52 kN-mm. The use of dual notch connections (STR-1 and STR-2) provides satisfactory performance, which is marked by meeting the minimum relative energy dissipation ratio at a 3.5% drift according to the ACI Committee 374.1-05.  The results show that the STR-2 beam-column connection is more capable of absorbing energy than the monolith beam-column connection and STR-1 beam connection. the value of monolithic cumulative energy dissipation is around 9333.07 kN-mm, STR-1 is 8336.76 kN-mm, and STR-2 is 10162.52 kN-mm. in principle, all three test specimens, monoliths, STR-1 and STR-2 provide satisfactory stability performance under lateral cyclic loads, because they still meet the minimum relative energy dissipation ratio at a deviation of 3.5% according to the ACI Committee 374.1 -05

Can Social Innovation advance the PMTCT programme? A South African reflection
Authors:   University of the Western Cape, Mdleleni Lwando , Velapi Linda
Published: July 2022

The prevention of mother to child transmission (PMTCT) programme is an initiative developed to enable health care practitioners to provide essential care to mothers in order to prevent the transmission of HIV to their infants. However, the PMTCT programme has not been reaching its intended prevention objectives. This paper identifies the social issues that elucidate the gap between PMTCT program goals and the role that Social Innovation could play in improving the status quo. Supporting Social Innovation in health helps reduce infectious diseases by empowering communities to become active participants in their health challenges through local adaptation of global strategies that facilitate the reduction of health system limitations. The article combines a review of the literature with empirical evidence extracted from research that has analyzed the postpartum experiences of mothers living with HIV in the context of the PMTCT program in Khayelitsha, Cape Town, South Africa in 2021. To address the research question, exploratory research has been adopted through a case study. The research is qualitative, exploratory and descriptive based on a case study constructed with secondary data. The results show that Social Innovation contributes to addressing healthcare challenges by providing more personal, analytical and preventive healthcare pathways. In addition, Social Innovation makes a critical contribution to addressing demographic challenges by helping those who are unable to access healthcare. This paper argues that Social Innovation in health is most effective when it occurs from the bottom up, as it is a process that engages the community and connects social change and health improvement through the diverse efforts of local actors. The article demonstrates that having local beneficiaries drive the development of a Social Innovation programme in health results in more viable and sustainable solutions. It also demonstrates that Social Innovation harnesses the ingenuity and willingness of community members, strengthening conventional health service systems and helping to achieve improved and sustainable health services.

The proposed system for voting in this project provides a decentralized platform on which all relevant voting information will be available to the public; therefore, security and transparency are the primary objectives of this project. This system uses facial recognition which helps the Election Commission to avoid rigging, bogus results, disputes, and uncertain situations. It uses artificial intelligence for facial recognition of the voters by validating it with a dummy database in which complete detail of a person is available including name, father's name, id number, thumb impression, photo, etc. Then voters can cast their vote easily. Our project infrastructure includes the admin panel which requires login credentials. The system is restricted and cannot be accessed outside of the polling station. In the polling station, firstly, the voter has to input their legal details (NIC) for authentication which redirects the voter to the Facial Recognition window, where the voter's face is validated through this method then all the candidates’ lists will be displayed on the screen of the voter. The program keeps the vote count of every candidate on submission of each vote and displays the result of the election as soon as the voting process ends, which means no delay in results. As our system is a Decentralized system, it also sends the vote count to every node in an encrypted way.

Мета статті – проаналізувати сценічний досвід артистки балету Ірини Дворовенко, набутий нею в Україні та за її межами під час роботи у найвідоміших балетних трупах світу. Методологія. У процесі дослідження використано низку методів: діалектичний – для аналізу персональної творчості, типологічний – з метою впорядкування історіографії та джерел, історичний – для пізнання історико-мистецьких процесів у вітчизняному балетному театрі впродовж останніх десятиліть, порівняння змісту та значення культурних подій, що відбувалися у царині українського театру на рубежі ХХ–ХХІ століть. Наукова новизна. Вперше досліджено віхи сценічної творчості Ірини Дворовенко – всесвітньо відомої балерини українського походження; залучено в науковий обіг нові джерела, що поглиблюють знання про предмет дослідження. Висновки. Балетний досвід, набутий Іриною Дворовенко в Україні та за кордоном (з 1993 р.) відрізняється за характером його змісту та художнім значенням. На Батьківщині артистка отримала високопрофесійну підготовку, яка допомогла їй здобути кілька престижних премій на міжнародних балетних конкурсах в Україні (1987), США (1990), Японії (1991) та ін. У період роботи на сцені Київського державного академічного театру опери та балету імені Т. Шевченка І. Дворовенко танцювала переважно сольні партії з вистав класичного репертуару. Під час роботи за кордоном (Гамбурзька опера, трупа Американського балетного театру) балерина виконувала ролі в балетах академічної спадщини, розширювала власний сценічний досвід завдяки постановкам балетмейстерів неокласичного та сучасного танцю (Д. Баланчин, К. Маккензі, Б. Стівенсон, Д. Кранко, Ф. Джофрі, К. Макміллан та ін.). Наприкінці сценічної кар’єри І. Дворовенко розгорнула активну мистецьку діяльність у царині педагогічної практики та кінематографа.
Фестивально-конкурсний рух у сфері народно-сценічного танцю України крізь призму сучасної мистецтвознавчої думки

Published: July 2022

Мета дослідження – проаналізувати сучасні тенденції мистецтвознавчого осмислення народно-хореографічного фестивально-конкурсного руху в Україні. Методологія. Застосовано методи аналізу й синтезу, порівняння, теоретичного узагальнення. Наукова новизна. Виявлено основні аспекти аналізу фестивально-конкурсного руху у сфері народно-сценічної хореографії України в сучасних мистецтвознавчих дослідженнях. Висновки. Серед численних наукових праць вітчизняних теоретиків та практиків щодо проблем розвитку української народно-сценічної хореографії, які порушують питання фестивально-конкурсного руху, вагомий масив становлять мистецтвознавчі праці з регіональних особливостей танцювальної культури. Серед таких досліджень переважають наукові розвідки, що стосуються західного регіону України: О. Бігус, Н. Марусик (Прикарпаття), А. Тимчула (Закарпаття), А. Підлипський, Л. Щур (Поділля), В. Гордєєв (Рівненське Полісся) та ін. Дослідники виокремлюють суто хореографічні (спеціалізовані, присвячені лише народно-сценічній хореографії чи декільком різновидам танцювального мистецтва); універсальні (охоплюють декілька видів мистецтва); монографічні (присвячені певній особистості). Всі сходяться на думці, що сучасні фестивалі та конкурси є не лише суто фаховими регуляторами та специфічними популярними типами культурно-дозвіллєвої діяльності, а й потужними механізмами в процесах культуротворення та націєтворення, формування національної свідомості. Фестивально-конкурсний рух у сфері народної хореографії в Україні в останні роки значно пожвавився, що, зокрема, пов’язано із запровадженням Всеукраїнського фестивалю-конкурсу народної хореографії ім. П. Вірського. Серед перспективних напрямів подальших наукових розробок – виявлення традиційних та інноваційних форм фестивалів та конкурсів у сфері народно-сценічного танцю, порівняння фестивально-конкурсної активності різних регіонів України, з’ясування ролі фестивалів та конкурсів для аматорських та професійних колективів народно-сценічного танцю та ін.

Мета статті – проаналізувати музичний доробок диригента Бориса Чистякова, пов’язаний зі створенням балетів за літературними творами українських письменників на українську національну тематику на сцені Київського державного академічного театру опери та балету ім. Т. Г. Шевченка. Методологія. Під час проведення дослідження застосовано аналітичний та порівняльний методи, а також історико-хронологічний – для відтворення панорами діяльності Б. Чистякова в хронологічній послідовності; мистецтвознавчий – для з’ясування художніх особливостей балетів. Наукова новизна. Вперше проведено спеціальне дослідження, присвячене виявленню ролі диригентської діяльності Б. Чистякова у втіленні балетних вистав на українську національну тематику у 1944–1963 роках. Висновки. Аналіз досліджень і публікацій довів, що заявлена проблематика розглядалася переважно у радянський період (Л. Житниченко, М. Загайкевич, В. Сурминська, Т. Швачко та ін.). Серед сучасної мистецтвознавчої літератури відомості про творчу працю Б. Чистякова у балеті подано в монографіях вітчизняних фахівців з історії музичного театру Ю. Станішевського та В. Туркевича. Основними віхами творчої біографії Б. Чистякова стало навчання в хореографічний студії І. Чистякова, Московському хореографічному технікумі (1925–1927), Київській консерваторії (1931–1935). Важливий етап – перехід на роботу до Київського ДАТОБ ім. Т. Шевченка, де він працював понад 40 років і був залучений до постановок понад 30 балетних вистав. Роль диригентської діяльності Б. Чистякова, насамперед, полягала у популяризації української національної тематики у вітчизняних балетах. Створені за його участі вистави «Лілея» К. Данькевича, «Лісова пісня» М. Скорульського, «Маруся Богуславка» А. Свєчнікова, «Тіні забутих предків» В. Кірейка вирізнялися сміливим мистецьким новаторством, переконливим втіленням партитури, власною диригентською інтерпретацією та високопрофесійною підготовкою творів до їхнього музичного виконання оркестром.

Authors: Lai Po-Yu , Wang Wen-Fu , Chang Ming-Che , Jhang Kai-Ming
Published: July 2022

Background: The global population with dementia is growing rapidly. Dementia patients have been included in the services of the long-term care Act 2.0, supported by Taiwan’s government since 2017. Community aging care centers are extensively established, which are places providing social connections and group physical and cognitive training programs for elderly people. Objective: To elucidate the efficacy of community aging care centers on cognitive function in people with dementia. Methods: A total of 1,277 patients with dementia diagnosed at the Changhua Christian Hospital outpatient departments were enrolled. A total of 113 patients who used community aging care centers and 452 subjects matched for age, education, and initial score of clinical dementia rating scale sum of boxes (CDR-SOB) control group were analyzed. The primary outcome was the change in CDR-SOB scores before and after utilization of community aging care centers. Results: The mean annual change of CDR-SOB scores were 1.72±2.97, 1.08±2.36, and 1.04±3.64 in control, Community Service Centers for Dementia, and community elderly stations, respectively, after about 1.5 years follow-up. Patients with dementia using community aging care centers had significantly less progression in CDR-SOB scores than those in the control group (–0.65; 95% CI: –1.27, –0.03; p = 0.041). Using one more day of community aging care centers per week significantly promotes 0.16 points of CDR-SOB decline (–0.16, 95% CI: –0.31; –0.00; p = 0.045). Conclusion: Community aging care centers, based on the long-term care Act 2.0 in Taiwan, were effective in delaying the decline in global function in people living with dementia.

In order to further increase the span length of the Optical Transport Network (OTN) transmission system, a combination of Raman amplifier and remotely optical pumped amplifier (ROPA) configuration scheme is recommended. Optimal EDF length, optimal ROPA position and OTN span limitation are obtained through simulations. A field-trial with 8*10 Gb/s in 380 km span system is carried out with the amplifier configuration of Raman amplifier plus first-order and second-order remotely pumped amplifier. By adding a second-order remote pump laser, the transmission limit is increased from 77.5 dB to 80.7 dB. Through detailed analysis of the system, it is concluded that the second-order remote pump can effectively transfer the pump power to the first-order remote pump wavelength, which greatly increases the pump power at the gain module, thereby increasing the gain of the RGU and reduce its noise. Moreover, the introduction of the second-order remote pump effectively weakened the self-excited effect and overcomes the shortcomings of the low pump power threshold of the first-order remote pump.

Authors: Yen Chih-Ping
Published: July 2022

We examine correlation coefficients for single-valued neutrosophic hesitant fuzzy sets (SVNHFSs) to point out their questionable results for the ideal alternative. Then, we propose three similarity measure methods to solve multi-criteria decision-making (MCDM) problems. Three applications, namely, ranking of alternatives, dysfunctional comments of turbine engine generators, and disease diagnoses for patients, illustrate the stability and effectivity of our new similarity. Our findings will help researchers deal with similarity measures in the future.

Published: July 2022

Physical Health is an important part of health education and health promotion in my country, and the health literacy level of students majoring in physical education in colleges and universities is an important factor in the development of health education in primary and secondary schools, and also directly affects the implementation of school health education in the future. The physical health evaluation of College students is frequently viewed as the multiple attribute decision making (MADM) issue. In our article, we combine the geometric Heronian mean (GHM) operator, generalized weighted Heronian mean (GWHM) operator with 2-tuple linguistic neutrosophic numbers (2TLNNs) to propose the generalized 2-tuple linguistic neutrosophic geometric HM (G2TLNGHM) operator and generalized 2-tuple linguistic neutrosophic weighted geometric HM (G2TLNWGHM) operator. Meanwhile, some ideal properties of built operator are studied. Then, the G2TLNWGHM operator is applied to deal with the MADM problems under 2TLNNs. Finally, an example for Physical health evaluation of College students is used to show the proposed methods.

Published: July 2022

BACKGROUND: Seafarers’ mental health is seriously affected by COVID-19. The pandemic could act as a catalyst for change with respect to seafarers’ mental health protection and promotion. OBJECTIVE: The study explores the main factors contributing to the mental health and wellbeing of seafarers. Moreover, elements to help seafarers lessen the impact of the pandemic on their work and life onboard are analyzed, and their role in developing a positive psychosocial environment and promoting a healthy workplace onboard are discussed. METHODS: The study involved the use of an ad hoc questionnaire and the adoption of both quantitative and qualitative methods. The sample included one hundred and five active seafarers. RESULTS: Ninety-six percent of the sample stated that mental health is a very or extremely important part of their general health. Seafarers perceive that their mental health has been seriously impacted by COVID-19. Major factors contributing to seafarers’ mental health and wellbeing reveal three groups of factors: rest and spare time-related factors, communication/relationship with the external world, and interaction and social life on board factors. CONCLUSIONS: Strategies suggested by seafarers for coping with “inevitable” psychological stress produced by COVID-19 and promoting their wellbeing include managerial, emotional, facilities-related (including communication infrastructure), physical, and social elements to promote wellbeing. Economic, intellectual, and spiritual elements also have to be taken into consideration and require further investigation. Building on seafarers’ insights and experiences, a healthy environment onboard should cultivate holistically the four main spheres of a healthy workplace (physical work environment, psychosocial work environment, personal health resources, and enterprise community involvement) and the five features of a healthy psychosocial environment (social, emotional, physical, intellectual and spiritual) under all circumstances, whether exceptional or ordinary.
Use of active aggregates in concrete as a guarantee of expansion of raw material base and reduction of cost of products
Authors: Kovalchuk O. , Zozulunets V.
Published: July 2022

Traditional natural materials (mainly granite and quartz) are usually used as aggregates for the manufacture of concrete products and structures. This raw material is tested, reliable and does not cause destruction during operation of structures. However, it is exhaustive and characterized by high cost. That is why it is advisable to consider the use of reactive (active) aggregates. Especially if you consider ways to eliminate alkaline corrosion. The development of alkaline concrete compositions with the use of active aggregates is the key to expanding the raw material base for the manufacture of building materials with a reduction in production costs compared to products based on traditional systems. The use of active mineral additives allows to reduce the content of free alkalis in the system, preventing the alkaline corrosion of hardened artificial stone. Simultaneously. the processes of interaction of the active siliceous component with alkalis in the cement system can be transferred from the category of destructive (such as destroying the structure of hardened stone) in constructive processes (binding these components into insoluble compounds during hydration and cement formation, without breaking its fixed structure and sealing material). Studies have shown the high efficiency of the proposed approaches for the binding of excess alkalis (more than 0.6%) and targeted synthesis of alkaline aluminosilicate-type tumors in the composition of artificial cement stone. At the same time, the issue of extending the results to control the formation of structures at different levels of concrete with the use of general construction cements requires further research, and the issue of stopping alkaline corrosion of hardened concrete has not been raised and is innovative from the point of view of domestic and world science.

Published: July 2022

Risks are inevitable in any construction project. Risk management methodology is used to eliminate or mitigate their consequences in construction project management. Risk management involves the establishment of risk awareness, integration of basic principles of risk policy and organizational integration. This allows you to actively prepare the project for the inevitable problems and increase transparency. This is an ongoing process throughout the project life cycle, as the risks will be constantly changing. Risk management is the process of identifying, assessing and responding to risks, so it is important to work as an integrated project team from the first phases to identify risks and effectively deal with them when they arise. The benefits of the process are a clearer understanding of the specific risks associated with the project, supported by solutions through detailed analysis and accumulation of data that can be used to manage risks in the future.

Ineffective implementation of risk management is often due to the lack of formalized procedures, lack of continuity in different phases of the project and inadequate integration of knowledge management and interaction between processes and parties.

The article reveals the importance of identifying risks at the very first stage, which allows to reduce the problems during their detection. Attention is paid to risk analysis and risk management at all stages of the project. This is especially important when building in compacted buildings.

A risk management plan is proposed, which provides timely identification and identification of potential problems and should be integrated into the project, from conceptual design to operation with extension to each stage. It should be based on principles such as risk identification, risk assessment, risk response and risk monitoring. The element of risk management algorithm is considered in more detail - identification of initial risks by creating and using a risk register, especially in the conditions of compacted construction.
Study of the factors influencing the choice of scaffolds for the implementation of the strengthening processes of building structures during reconstruction
Authors: Tonkacheiev H. , Rudnieva I.
Published: July 2022

The article clarifies the influence of the technical condition of the structure, as well as the structural, technological and organizational parameters that determine the organizational and technological scheme for the production of construction works for reconstruction, as major factors affecting the choice of scaffolds for the implementation of strengthening processes of building structures.

The choice of scaffolds for the implementation of the processes of strengthening building structures during reconstruction is a complex organizational and technological process that requires analysis, preparation and verification of decisions. Reconstruction works should be carried out in a short time with a combination of two technologies in site (industrial, production, and construction).  During the repair and reconstruction of existing workshops, a large volume of assembly and repair operations during the replacement and reinforcement of building structures is carried out inside the building at a considerable height. Labor costs for the arrangement of the scaffold often exceed the labor costs for the main work that are performed using these funds, which in turn affects the cost of the reconstruction project and the time it takes to complete the work. In these conditions, the labor intensity of construction and installation works sharply increases. Therefore, for the conditions of reconstruction, it is necessary to investigate the regularities of the choice of scaffolds for the implementation of the processes of strengthening building structures, depending on a number of factors. In order to study the features and properties of the scaffolds, a set of influencing factors was found and the final indicators for scaffolds types were studied. They are obtained from the analysis of the structural, technological and organizational parameters of the scaffold. of the whole set of factors, the most important and complex subgroup is the type of equipment and equipment layout in workshops. For their selection and analysis, objects of mechanical engineering and metallurgy were considered, taking into account the nature and severity of products, the nature of the technological process and the size of the shops. Further, according to the nomenclature of existing scaffolds, those parameters and factors should be selected that can be used when strengthening and replacing the corresponding building structures.

Published: July 2022

The progress of science and technology significantly depends on the success in creating new materials. Composite materials are a heterogeneous structure formed by a combination of reinforcing elements and isotropic binder (binder) material, currently widely used in various fields of technology. but for the economy is more important mass application. For this purpose, more thorough and long-term research and experimental implementations are carried out, which require significant intellectual and material costs. Development of structural elements using basalt fiber began in NDIBV since 1987. and experimental samples of prestressed concrete structures with basalt-plastic reinforcement. Research to identify the interaction of cement with basalt fiber and the design of effective concrete structures using basalt reinforcement. Concrete beams with basalt reinforcement were successfully tested. Unfortunately, the results of research have not been widely implemented. Therefore, this article is devoted to the problems of mass introduction into construction practice of various types of composite materials, including basalt reinforcement. The advantages and disadvantages of composite reinforcement in comparison with steel are discussed. During the theoretical and experimental studies, both positive and negative aspects of the use of basalt reinforcement were identified. So experiments have shown that basalt fiber loses strength in the environment of Portland cement stone. But this shortcoming has been overcome by the efforts of scientists, it is important to use certain defects of basalt fibers for specific conditions. There are the following main types of basalt fibers:

1) basalt continuous fibers with a diameter of 8 - 11 microns, 12 - 14 microns, 16 - 20 microns with a fiber length of 25 - 50 mm and more;

2) staple short fibers with a diameter of 6 - 12 microns and a length of 5 - 10 mm and several diameters;

3) basalt superthin fibers with a diameter of 0.5 - 1 microns with a length of 10 - 50 mm;

4) coarse basalt fibers with a diameter of 100 - 400 microns.

To create structures with certain properties for specific conditions, appropriate basalt fibers are selected. According to the research results, recommendations and normative documents have been developed. Suggestions for measures to improve and successfully widely use composite elements for reinforcement of concrete structures.
On the use of green plantations, winter gardens and greenhouses on the roofs of buildings and structures

The constant growth of the urban population has led to a number of serious social, economic and environmental problems. Due to the density of urban development, there is almost no space left for greenery, parks, squares. Not only urban recreational areas are being reduced, but also suburban green areas, which act as green urban belts. Such green belts are a source of oxygen, a zone of conservation of biodiversity of phyto- and zoocenoses, migration routes for biota from the urban environment to the natural and vice versa. In addition, they maintain the climate balance of the urban system, protecting it from wind, temperature changes, flooding, landslides and floods.

Currently, the urban system spreads horizontally and vertically, which dramatically reduces the attractiveness of the landscape. The situation is complicated by economic reasons: the cost of land in the city center is very high. Therefore, it is more profitable to give it for construction, rather than creating recreation areas. Due to the lack of green areas in the central areas, there is an effect of "heat island" of urban centers, when the temperature difference between the central urban and suburban areas is about 4… 7 ° C.

Factors that change the microclimate of urban coenoses also include: air pollution (change in its composition, which is expressed in an increase in the content of solid suspended particles and gaseous impurities); change in heat transfer due to the closed horizon, thermophysical properties of urban surfaces (heat capacity, reflectivity of impurities); artificial formation of heat flows during heating, operation of vehicles, at industrial enterprises. Economic and environmental problems of cities lead to social ones, when the level of chronic diseases increases, the psycho-emotional state of a person deteriorates, and the birth rate decreases. Therefore, modern cities need to use modern energy-efficient technologies on roofs - "green structures", conservatories and greenhouses, which are able to solve environmental, economic and social problems.
