Productivity of Certain Varieties of Apples and Importance of Their Gene Formation
Authors: Sadigov A.
Published: September 2024

Due to the diversity of its natural and historical conditions, Azerbaijan is one of the centers of the initial formation of many plants, having a great genetic richness of the plant world. A large number of valuable varieties and forms of food and agricultural plants have been created through folk selection and scientific selection, with the history of agriculture covering several millennia. However, massive and anthropogenic disturbances of all these natural and cultural heritage ecosystems, which are the irreplaceable wealth of the people, created a large number of valuable varieties and forms of ecological and agricultural plants. However, all this natural and cultural heritage, which is the irreplaceable wealth of the people, is threatened with destruction as a result of mass and anthropogenic disturbances of ecosystems, ecological and agricultural changes, and the wide application of modern breeding achievements. In addition to all this, the study, protection, and effective use of the gene pool of the apple plant in the country is one of the main factors. In this regard, based on our long-term research, with the efficient use of the gene pool of the apple plant in Azerbaijan, new “spur”-type selection varieties (Nigar, Ziya, Zirva, Marfa, Sulh, Gobustan, Zumrud, Kyzyld Taj, Khazar, Eldar, Ulvi, Nübar, Vatan, Makhmari, Nuran, Sarvan, Chiraggala, Davamli, Emil, Elvin, Paizliq Guba, Zizliq Guba, Shabran, Sadaf and Sevinj) were created by us. In the article, the parental pairs of those cultivars are reflected in the ripening period, ripening, fruiting periods, tree parameters (height, diameter of the umbel, circumference of the stem), productivity indicators, leaf surface, infection rates of scab disease, average mass of fruits and tasting prices. At the same time, the article contains the introduction, research conditions, methodology, material, results, discussion, recommendations, and used literature sources.

Background

Encouraging positive parenting practices through evidence-based interventions is vital for the achievement of SDG target 16.2, which aims to eradicate all forms of violence against children while promoting their safety and mental wellbeing. As low- and middle- income countries increasingly adopt parenting programs, policymakers and implementers face the challenge of efficiently transporting, adapting, and implementing them across multiple settings.

Purpose

This study seeks to evaluate the real-world experiences, challenges, and best practices in implementing parent support programs in Botswana.

Method

A series of interviews with program implementers and stakeholders from governmental and non-governmental organizations were conducted. Key informants from governmental and non-governmental institutions were recruited through purposive and snowball sampling and 17 practitioners participated in the study. Data collection was carried out through online Zoom video conferencing at a convenient time and location for participants.

Findings

The findings indicate several factors that contribute to the successful implementation of parenting programs in Botswana, including (a) enabling factors such as supportive policies, regulations and guidelines, (b) innovative factors such as capacity building, program adaptation and mixed method program delivery, (c) bridging factors through collaborations with skilled organizations, and (d) intra-organizational factors such as organizational resources, program sustainability, and support for program staff.

Conclusion

No single organization or strategy can sustainably foster positive parenting support in Botswana. Instead, a collective and collaborative learning approach is necessary to develop lasting and scalable solutions.

It is often called the taiga, and in general it covers about 10 % of the Earth's landmass. A significant part of the taiga grows in the northern latitudes. The peculiarities of the climate of these latitudes affect the peculiarities of the dynamics of successions of forests growing there, first of all, the rate of recovery after natural and anthropogenic disturbances. The article presents an analysis of literary sources on the features of the structure of cryolithozone soils, as well as the results of a field survey of logging in previous years, located in the north of the Leningrad region.
COVERAGE OF THE RUSSIAN-UKRAINIAN WAR IN RESEARCH ARTICLES FROM THE INTERNATIONAL SCIENTIFIC DATABASES SCOPUS and WEB of SCIENCE for 2023
Authors:   Kharkiv State Academy of Culture, Kysliuk K.
Published: September 2024

The paper sets out the quantitative and qualitative characteristics of foreign coverage of the Russian-Ukrainian war. The subject of the study was the articles with the keywords «Ukraine» and «war» in the title in the international scientometric databases Scopus and Web of Sciences for the year 2023. It was noted that in quantitative terms, in the last two years, precisely because of large-scale hostilities on the territory of the country, interest in Ukrainian studies has increased sharply. It is considered from favorable positions for our country, precisely as «war», «invasion», «aggression», but not «conflict» or «crisis». Unlike domestic publications, which are mostly devoted to internal issues, the authors of foreign articles focus their attention on the external effects of the Russian-Ukrainian war in a broad socio-economic and geopolitical context. The largest specific weight is made up of publications on media topics. The review of military aspects is limited to a discussion of the use of aviation, small drones, and the possibility of nuclear escalation. Most of the few articles, the subject of which can be attributed to the field of culture, are related to the such topics as: a) art, b) national identity, c) cultural policy and cultural heritage, which are also published by domestic authors in specialized Ukrainian journals on cultural studies. Instead, the topic of «women and war» is considered much more broadly. However, so far there are no attempts to conceptualize the essence and limits of the new socio-cultural reality, the formation of which was created by the Russian invasion of Ukraine. Keywords: bibliography, war, culturology, culture, Russian-Ukrainian war, Ukraine, Ukrainian culture

The authors of the article investigate the problem of scientific and expositional work of museums of Ukraine as an important component in the system of national-patriotic education of the population, cultural-educational and pedagogical activities. The topicality and scientific novelty of the article are determined by its purpose: to analyze the academic discipline «Museum sciences» at the Chair of Cultural Studies of Mariupol State University; the authors of the article try to draw the attention of humanitarians, students of cultural studies in particular, to the place of museum exposition in the complex system of modern social and cultural relations in Ukraine and the justification of the necessity to use the latest technologies in the scientific and exhibition activities of domestic museums. The special attention of the authors is focused on those components of scientific and exhibition work of museums that determine their special emotional and extraordinary popularity among visitors. Objects of cultural heritage acquire the status of objects of the museum fund, when they get to the museum, a stable and at the same time permanent phenomenon: museum objects in the exposition state an era for a certain period, but within a period of time the perspective of its perception as an event changes. A similar situation occurs with the environment. This, in turn, requires considering scientific and exhibition activities in museums as a process that requires constant improvement, especially in modern conditions of quick development of the information society. The material presented in the article contributes to the formation of a realistic view of the state of affairs in national museum sciences, in the issues of creating new and rebuilding existing museum expositions in particular. Keywords: museum sciences, Mariupol State University, Chair of Cultural Studies, educational discipline «Museum sciences», scientific and exhibition work of museums.
SYNERGISTIC PRINCIPLES IN ART EDUCATION
Authors:   National Academy of Management of Culture and Arts, Shumeiko L.
Published: September 2024

The sphere of national art education has long been in a state of bifurcation, as it is being formed in the context of a cascade of reforms, geopolitical and cultural challenges of the present. On the basis of the study of synergetics as an interdisciplinary science that studies the principles of emergence, self-organisation, maintenance of stability and disintegration of systems (structures) of different nature, the essential characteristics and manifestation of the main principles of synergetic knowledge in the system of art education are formed. Through the identified synergistic principles, the modern development of art education is comprehended not only as an open multi-level system, but primarily as a component of culture. The research methodology is based on the use of the method of terminological analysis to define such concepts as: «synergetics», «principles of synergetics», «bifurcation», «homeostasis», «attractor», which made it possible to formulate and comprehensively cover the effect of the main synergistic principles in art education. The use of the analytical method helped to identify the conceptual foundations of further prospects for the implementation of synergetic principles in the artistic and educational space in the context of cultural knowledge. We associate the effectiveness of the implemented state reforms in the field of national art education with the importance of forming an artistic and educational space based on the main synergetic principles, which will greatly facilitate the understanding of most processes and facilitate the rapid adaptation of a complex system of art education to new requirements and challenges of today, and thus its gradual and successful transition to a new evolutionary level. Key words: synergy, synergetic knowledge, principles of synergy, synergetic education, principles of synergy in art education.

Authors:   Mariupol State University, Stadnyk A. , Borodai A. ,   Mariupol State University
Published: September 2024

The article analyzes the forced migration of Ukrainians as a result of the armed aggression of the Russian Federation against Ukraine, with a focus on the main demographic consequences. It is determined that the Russian invasion of Ukraine, which began on February 24, 2022, has led to an unprecedented humanitarian crisis, dramatically changing the way Ukrainian society, European countries and the whole world function. It is noted that these processes have not ignored the sphere of international migration: instead of going abroad to work or study, which has long been the most common form of migration of Ukrainians to other countries, forced migration has become a determining factor in the current situation. It is noted that a large number of Ukrainians have crossed the border in search of a safe environment (3.6 million people left Ukraine during the first month of the full-scale war). It is proved that the massive nature of the forced migration of the Ukrainian population has led to a number of significant problems in the country: increased unemployment and social tension, a decline in the welfare of the population, and an increasing split in society. The author analyzes the main conditions for the return of Ukrainians, the consequences of migration for the future of the country, the demographic structure of migrants and the factors that will affect the intensity and directions of further migration of the Ukrainian population abroad, including the expansion or narrowing of the area of hostilities; progress in the de-occupation of temporarily occupied territories; resilience of local critical infrastructure; direct shelling of settlements by Russian troops; the emergence of man-made or natural crises; the level of socio-economic development. The methods of preventing problems at the stage of post-war reconstruction in the context of the current migration crisis based on its comprehensive analysis are determined. Keywords: forced migration, refugee, population of Ukraine, demographic consequences.

A formação dos aspectos psicológicos e físicos ao longo da vida impacta profundamente o processo de envelhecimento. A pandemia da Covid-19 intensificou esses problemas devido às medidas de distanciamento social, agravando a solidão e os desafios emocionais. Este estudo se justifica pela necessidade de compreender as mudanças emocionais dos residentes em ILPIs durante e após a pandemia. O objetivo é analisar a condição psicoemocional dos idosos em duas ILPIs de Araguari-MG no contexto pós-pandemia. A metodologia adotada inclui uma análise quali-quantitativa de corte transversal, utilizando o Mini Exame do Estado Mental e entrevistas individuais para avaliar a saúde mental e emocional dos idosos. As ILPIs selecionadas representam uma amostra significativa da população idosa institucionalizada na cidade. Os resultados indicam que a pandemia intensificou sentimentos de solidão e isolamento, ressaltando a necessidade de políticas públicas que abordem a saúde psicoemocional dos idosos. Observou-se uma correlação significativa entre o apoio emocional recebido e a melhoria na qualidade de vida, sugerindo que intervenções direcionadas podem mitigar os efeitos negativos do isolamento. Conclui-se que a manutenção da qualidade de vida dos idosos requer atenção contínua e integrada aos aspectos físicos e emocionais, prevenindo a perpetuação do isolamento e do descaso.

In vitro effect of zirconia type on shear bond strength to feldspathic porcelain and wear of the opposing teeth
Authors: Rafiei Amirhossein , Fakhrzadeh Vahid , moslehifard Elnaz , Ranjbar Ghazal
Published: September 2024

Background. Multilayer zirconia has more optical and aesthetic features than regular zirconia. Therefore, its mechanical properties should be compared with monochromatic zirconia. Among the mechanical characteristics that can be checked are the wear of the opposite tooth and the bond to the porcelain. This study assessed the effect of zirconia type (multilayer versus monochromatic) on the shear bond strength (SBS) to feldspathic porcelain and the wear of the opposing teeth. Methods. The present in vitro study was conducted in two phases. In the first phase, 15 multilayer and 15 monochromatic zirconia blocks measuring 10×5×5 mm were designed, milled, sintered, veneered with porcelain, and underwent thermocycling. Their SBS was then measured in a universal testing machine. In the second phase, 15 multilayer and 15 monochromatic zirconia blocks were placed in a chewing simulator, and 30 sound premolars served as antagonistic teeth. The magnitude of wear of the buccal cusp of premolars was quantified from a 4-mm reference point after 100000 cycles. Data were analyzed by independent t test (α=0.05). Results. The mean SBS of monochromatic zirconia to porcelain (24.49±3.58 MP) was slightly higher than that of multilayer zirconia (22.98±2.98 MP), but the difference was not significant (P>0.05). The mean wear of the opposing teeth was also slightly higher in the monochromatic group (284.1±66.53 µm) than in the multilayer group (263.2±58.69 µm), but this difference was not significant either (P>0.05). Conclusion. Monochromatic and multilayer zirconia showed comparable SBS to feldspathic porcelain and caused comparable wear of the opposing teeth in vitro. Thus, multilayer zirconia may serve as an alternative to monochromatic zirconia.

Published: September 2024

Background. This study evaluated the gingival crevicular fluid (GCF) and Peri- implant crevicular fluid (PICF) concentrations of interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and active metalloproteinase-8 (a-MMP-8) in sites with healthy conditions vs. sites affected by periodontitis (PER) and peri-implantitis (PIM). Methods. Periodontally healthy (PH) sites with PER, sites with peri-implant health (PIH), and sites with PIM were investigated intra-individually, according to the inclusion criteria of each group. Probing pocket depth (PPD), plaque index, gingival index, and the presence or absence of bleeding on probing (BoP) were evaluated. In GCF and PICF samples, IL-1β, IL-6, and TNF-α were quantified by ELISA Duoset® kit in combination with Ultramark® micro-ELISA digital reader; a-MMP8 concentration was analyzed by a chairside test (Perio/ImplantSafe®) in combination with a digital reader (ORALyzer®). Results. The concentrations of IL-6 and IL-1β, TNF-α, and a-MMP-8 were significantly higher in the PIM and PER sites compared to healthy sites (P<0.05). Significantly higher concentrations of IL-1β and a-MMP-8 were found in PIM vs. PER sites (P<0.05), while the concentrations of IL-6 and TNF-α did not differ between the PIM and PER groups (P>0.05). Conclusion. aMMP-8, IL-6, IL-1β, and TNF-α presented higher GCF/PICF concentrations in diseased periodontal and peri-implant sites. However, only the concentrations of IL-1β and a-MMP-8 were significantly higher in PIM than in PER sites.

Published: September 2024

Introduction: Vertical jump performance is an important measure of leg power and explosiveness in sports. Somatotype, referring to body shape and composition. It may relate to vertical jump capacity. This study aimed to compare vertical jump, peak anaerobic power, and relative anaerobic capabilities between ectomorphic-mesomorph and mesomorphic-ectomorph somatotypes among sedentary male students. Methods: A total number of 26 students participated in this study. Participants underwent anthropometric assessments to determine Heath-Carter somatotype ratings. Additionally, countermovement jumps were performed to evaluate vertical jump height, estimate peak anaerobic power via the Sayers equation, and calculate a power-to-body mass ratio. Results: No statistically significant differences were found between ectomorphic-mesomorphs (n=15) and mesomorphic-ectomorphs (n=11) for vertical jump (54.47 ± 8.33 cm vs 57.09 ± 6.28 cm, p = 0.25), peak anaerobic power (3576 ± 542.01 W vs 3473.47 ± 538.71 W, p = 0.64), or power-to-body mass ratio (69.97 ± 10.51 W/kg vs 65.10 ± 7.46 W/kg, p = 0.18). Conclusion: While this initial study suggested no substantial performance differences based on somatotype, further research with increased statistical power through larger sample sizes is necessary to conclusively determine relationships between physique and anaerobic capacities in the general population. Matching and tracking athletes over sports training may also clarify advantages conferred by morphology alone.

Results: The data obtained regarding height and weight, muscle percentage (45.05 ± 5.02), bone (16.25 ± 1.72) and fat percentage (7.98 ± 1.32) are comparable to the obtained information of rugby union players who play in the three quarters position. Participants were predominantly classified as balanced mesomorphs, which are characterized by increased skeletal muscle development. Discussion: Body composition as well as somatotype values are similar to  other studies results according to elite athletes in intermittent sports that do not require high fat percentages. Conclusion: Despite being tall and with large body mass athletes, their high muscle percentage can provide this type of athlete greater power and speed, necessary to support the high demands of competition in this sport.

Introduction: Students spend most of their day at school sitting in their classroom furniture which is not quite the right size for students. This can be uncomfortable and even lead to back pain, leg cramps, and other problems. Method: Students’ body size for good posture while sitting, include popliteal to floor height, elbow to seat height, thigh thickness, sitting height, buttock to popliteal length, buttock to knee length, elbow to elbow breadth, the width of bitrochanter, subscapular height, and sitting shoulder height, and one standing is stature. Similarly, dimensions of chair-with-table, like seat height, the upper edge of the backrest, seat width, seat depth, table length, table width, table height, backrest height, and footrest currently used in the classroom were taken.  The study compared students' anthropometry data with the furniture dimension data to obtain a match or mismatch between them with the help of standard mismatch equations. Results: The study reported that the mean body measurements of males are larger than females except for the width of bitrochanter. Seat width, seat depth, backrest height, and the upper edge of the backrest showed high mismatch percentages in students when patronising chairs. Table length reported high mismatch percentages among students. Conclusion: Using the users’ body sizes for furniture design will reduce musculoskeletal disorders and improve users’ sitting position. The recommended dimensions in furniture design will ergonomically fit students’ anthropometric measurements.

Introduction: This study aimed to determine and compare the anthropometric characteristics and somatotypes of male athletes participating in volleyball, basketball, and soccer at Madonna University, Nigeria. Methods: A cross-sectional study was conducted with 50 male athletes (15 volleyball, 15 basketball, 20 soccer players) aged 18-25 years. Anthropometric measurements, including height, weight, skinfold thicknesses, bone girths, and circumferences, were obtained. Somatotype was estimated using the Heath-Carter method. One-way ANOVA was used to compare the differences between the sports. Results: Basketball players were taller and heavier than the other athletes. Significant differences were found in height (p=0.033), triceps skinfold thickness (p=0.049), and humerus breadth (p=0.013) among the three sports. Volleyball players exhibited the highest endomorphy (4.03 ± 2.09) and mesomorphy (5.16 ± 1.44) scores, while soccer players showed the lowest endomorphy (2.97 ± 0.32) and highest ectomorphy (1.65 ± 0.71) values. The majority of athletes across all three sports were classified as endomorphic mesomorphs. Conclusion: The study provides insights into sport-specific physical characteristics and body compositions among Nigerian collegiate athletes, which may inform talent identification and training strategies. The findings highlight the need for further research to understand the unique attributes of athletes in these sports within the Nigerian context.

During the reform era, regional autonomy has been implemented to develop each regency/city effectively and effi-ciently. The central government has delegated authority and given intergovernmental transfers to local governments to regulate and determine the priorities of their regional development. Unfortunately, the effectiveness of the trans-fer by increasing capital expenditure allocation often becomes controversial. In the recent 5 years, the percentage of capital expenditure realization is lower than that of the capital expenditure. In 2018, the average percentage of regional personnel expenditure in Indonesia was around 35.6%, while the capital expenditure was only 19.4% (DJPK, 2018). In 2022, the situation was getting worse because the personnel expenditure was allocated 62.5%, while the capital expenditure was only 15.8% (DJPK, 2022). Although the Minister of Home Affairs Regulation Number 27 of 2013 has stated that each region should allocate its capital expenditure at least 30% from the APBD, but in reality there are still many regions that haven’t complied with this rule. In Riau, until 2021 there have been no regencies/cities that can fulfill the regulation. The purpose of this paper is to analyze the impact of General Alloca-tion Fund (DAU), Special Allocation Fund (DAK), Revenue Sharing Fund (DBH) and Local Own-Source Revenue (PAD) on capital expenditure in regencies/cities of Riau in the period of 2018-2021. The analytical method applys multiple regression analysis based on Pooled Least Square model. The result reveals that capital expenditure is sig-nificantly and positively affected by DAK and PAD. Meanwhile, DBH and DAU have insignificant effect on capital expenditure of Riau in 2018-2021

This study aims to prove the impact of employee achievement (EA) and an internal control system (ICS) on company performance (CP). Besides, verifying the influence of the ICS on EA and the mediation effect of EA on the association between ICS and CP become the other purposes. This study utilizes 120 employees from 15 general insurance companies in Bandung as the sample by snowball sampling technique and covariance-based structural equation model (CBSEM) to analyze the responses to the questionnaire. Because of the responses, this study tests their validity and reliability. After achieving them, this study detects and finds the response fitness with the CBSEM. Based on the hypothesis testing, this study demonstrates three evidence. Firstly, EA and ICS have a positive tendency towards CP. Secondly, a positive association between ICS and EA occurs. Finally, the mediating effect of EA on the relationship between ICS and CP exists. Considering these research results, ICS is the primary driver; therefore, general insurance companies must focus on five aspects: (1) environmental control, (2) risk valuation, (3) controlling the action, (4) information and communication, and (5) monitoring action, to make employees perform, causing the company to attain its goals.

The Denpasar City Police Multipurpose Building project experienced constraints on project implementation delays due to the Eid al-Fitr holiday. This obstacle resulted in a delay in the progress of project realization by 9.346% or 19 days. The planned progress in week 20 is 66.521%, but the realization in the field has only reached 57.175%. The remaining duration of the project work is 76 days. This analysis aims to optimize the cost and duration of the remaining work with the addition of labor using the least cost analysis method, so that the project can be completed on time and the contractor does not get a fine. The analysis uses primary data in the form of observation costs, facility costs, overhead costs and unexpected costs. Then secondary data in the form of contractor unit price analysis, cost budget plan (RAB), and S curve. The data is analyzed starting from the remaining project work, crashing duration, to finding the cost slope in each job, and using the least cost analysis method to get the optimum cost and duration. The results of the analysis state that the project optimization cost after acceleration is Rp 3,077,713,130.90 with the duration of project implementation accelerated from 76 days to 57 days. The acceleration of the project duration will save the project cost of Rp. 18,428,493.93.

Abstract Good quality concrete is concrete whose basic ingredients are also of good quality. One of the ingredients that make up concrete that determines the compressive strength of concrete is coarse aggregate. Coarse aggregate itself is a resource that is easy to obtain, widely available in nature and in various types. According to its origin, coarse aggregate used as a building material for concrete can be divided into two, namely natural aggregate obtained from rivers and artificial aggregate obtained from crushed stone.  This research was carried out using 3 variations, namely 100% Kali Manggaran stone, 100% Tapa Utama crushed stone, and a combination of 50% Manggaran 50% Tapa Utama with a plan to use concrete quality K225 or 18.68 MPa, according to the minimum requirements of the concrete quality plan for structural work. The results of the research show that the use of 100% Manggaran river stone at a concrete age of 14 days is 14,834 MPa and 18,117 MPa. Meanwhile, the use of 100% crushed stone tapa Utama obtained a concrete compressive strength of 17,256 MPa at a concrete age of 14 days and 21,045 MPa at an age of 28 days and was in accordance with the planned concrete quality. The maximum compressive strength is the 100% crushed stone tapa Utama concrete variation with a concrete age of 28 days. Keywords: Coarse Aggregate, Compressive Strength of Concrete, Manggaran River Stone, Tapa Utama Crushed Stone
