DES and IIoT fusion approach towards real-time synchronization of physical and digital components in manufacturing processes
Authors:   Széchenyi István University, Győr, Hungary, Monek Gergő Dávid , Fischer Szabolcs ,   Széchenyi István University, Győr, Hungary
Published: September 2023

Today's manufacturing systems offer more products to meet specific needs. Complex production systems in rapidly changing environments result from product variation, shorter product life cycles, and supply chain expansion. A cyber-physical production system (CPPS) can use manufacturing and logistics data to plan, monitor, and control production. Discrete event simulation (DES) and digital twin (DT) technology can model and evaluate manufacturing and logistics processes using high-level decision support and process monitoring. The cost of collecting input data from different enterprise data sources and mapping it into models and the lack of qualified experts prevent the widespread use of these methods in industry, especially in small and medium-sized enterprises and larger multinational companies. This research aims to create a modular digital twin framework for manufacturing process optimization and real-time monitoring in an industrial environment with few components. The system can identify and track the product through the manufacturing cycle while updating the DT in real-time and can be used independently to collect input parameters for discrete event-driven simulations and even for automatic simulation building in the future. The framework's operation will be shown through an example. With the proposed IIoT (industrial internet of things) system integration, it can detect faults and warn of deviations from normal operation, and DT can drastically reduce data collection and model building and support model reusability, increasing sustainability.
DNAJC6 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: September 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that DnaJ heat shock protein family (Hsp40) member C6, encoded by DNAJC6, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. DNAJC6 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of DNAJC6 in primary tumors was correlated with overall, distant metastasis-free and recurrence-free survival. Modulation of DNAJC6 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Các học thuyết bảo vệ môi trường lạ đời: Một góc nhìn khác trong nghị sự bảo vệ môi trường
Authors: La Viet-Phuong , Nguyen Minh-Hoang
Published: September 2023

Trong quá trình phát triển của phong trào bảo vệ môi trường, đã xuất hiện nhiều học thuyết và trường phái khác nhau. Một trong số này thuộc về các học thuyết bảo vệ môi trường lạ đời (đôi khi mang sắc thái cực đoan), thể hiện sự tận tụy và độc đáo trong việc bảo vệ môi trường với mọi biện pháp. Vì họ đặt môi trường lên hàng đầu, nên những quan điểm này thường phản ánh quan điểm cấp tiến và đôi khi khá khác biệt về quan hệ giữa con người và môi trường. Vì vậy, chúng thường không được chấp nhận rộng rãi hoặc không thực tế. Tuy nhiên, dưới góc nhìn tập trung vào bảo vệ môi trường, những học thuyết này cũng đem đến cho chúng ta nhận thức về những xung đột lợi ích mà nhiều nhà hoạt động môi trường thường bỏ qua. Chúng cũng làm nổi bật mục tiêu quan trọng của việc hài hòa lợi ích của con người và thiên nhiên. Bài viết này sẽ tập trung phân tích một số học thuyết bảo vệ môi trường lạ đời phổ biến nhất, để mang đến một cái nhìn đa chiều về vấn đề môi trường.

Beneficios Fiscais e Planeamento Fiscal
Authors: Inocencio Flavio Gualter Inacio
Published: September 2023

Este Artigo está dividido em duas partes: a primeira explora os fundamentos para concessão de incentivos fiscais em Angola e analisa a natureza fragmentária dos benefícios fiscais no Direito Angolano. Particularmente relevante, são os incentivos fiscais estabelecidos nos termos da Lei de Investimento Privado para atrair investimento estrangeiro. No entanto, o Direito Angolano tem incentivos fiscais diferenciados para a Indústria do Petróleo e do Gás Natural, a Indústria Mineira, as Pequenas e Médias Empresas entre outros. Assim, considerando que os investidores e os contribuintes baseiam as suas decisões de investimento considerando factores diversos como o acesso a um sistema judicial eficiente que garanta a protecção dos direitos de propriedade, a presença de infraestruturas modernas, acesso a terra e ao capital entre outros, alguns autores estão cépticos quanto ao papel dos incentivos fiscais como uma ferramenta eficiente de política pública para atracção de investimento.A segunda parte do artigo explora os conceitos de planeamento fiscal, elisão fiscal e fraude fiscal, considerando a doutrina jurídica e analisa a cláusula específica anti-abuso em Angola e a possibilidade da introdução de uma cláusula geral anti-abuso, considerando a nova reforma fiscal. Por último, o artigo conclui com uma análise do Decreto Presidencial nº147/13 com regras modernas acerca dos preços de transferência. .
Investigating the subjective and objective efficacy of a cognitive behavioral therapy for insomnia (CBT-I)-based smartphone app on sleep: a randomized controlled trial
Authors: Hinterberger Alexandra , Eigl Esther-Sevil , Schwemlein Robyn Nina , Topalidis Pavlos , Schabus Manuel
Published: September 2023

Due to insufficient treatment options for sleep disorders, effective solutions are urgently needed. We evaluate the effects of a CBT-I-based app combining sleep training with subjective and objective sleep monitoring on i) sleep and ii) subjective-objective sleep discrepancies (SOSD) as known for insomnia. Fifty-seven volunteers (20-76 years; MAge=45.67±16.38; 39 female) suffering from sleep problems were randomly assigned to an experimental group (EG, n=28) or a waitlist control group (CG, n=29). During the 6-week app phase, the EG used the CBT-I-based program and a heart-rate sensor for daily sleep monitoring and -feedback, while the CG used the sleep monitoring only. Sleep was measured i) subjectively via questionnaires (Insomnia Severity Index, ISI; Pittsburgh Sleep Quality Index, PSQI), ii) objectively via ambulatory polysomnography (PSG), and iii) continuously via heart-rate sensor and sleep diaries during the app phase. Data revealed interactions for ISI (p=.003) and PSQI (p=.050), indicating training-specific improvements in EG, yet not in CG. While PSG-derived outcomes generally appear to be less training-specific, a statistical trend towards a reduction in WASO was found in EG (p=.061). Regarding changes in SOSD, results indicate improvements during app phase (EG) for SE, SOL and WASO (p’s ≤.022); for TST both groups show a SOSD reduction. The findings indicate beneficial effects of a novel smartphone app on sleep and SOSD. More scientific evaluation of such digital programs is needed and should ultimately help to reduce the gap in non-pharmacological treatment care for insomnia.
Gravitation and thermodynamic irreversibility for primary matter and antimatter
Authors: Tsitverblit Naftali
Published: September 2023

The irreversibility of macroscopic processes inthe universe since its material outset is inferredto stem from such a generalization of the first law of thermodynamics as also covers gravitation. Growthof the total entropy in a comoving \mbox{Friedmann} volumeis launched when such a global equilibrium is perturbed witheffects of attractive gravitation. It is then underlain by twoopposite time arrows definable with the respective gravitationalenergies of material phases equally created in such a volume from vacuum decay. Due to thermodynamic equilibrium of this process, either of these phases arises homogeneously throughout its entire\mbox{Friedmann} universe. Having first randomly dominated their oppositetime arrows, such matter and antimatter thereby polarize the disintegratingvacuum phase with their independent effects of attractive gravitation and henceseparate these created phases in terms of their time arrows. For two gravitationallyindependent material phases created cosmically, their macroscopic inverse of timeis equivalent to the identical change of their creation entropies with therespective times. Driven by repulsion of the decaying vacuum phase, cosmic expansion thus largely begets mutually inaccessible matter and antimatter.Dilated at their enhanced densities, either such a progressing timealone still underlies a nongravitational manifestation of the respective entropy growth as well.
The effect of instructed refreshing on working memory: Is the memory boost a function of refreshing frequency or refreshing duration?
Authors: Vergauwe Evie , Souza Alessandra S. , Langerock Naomi , Oberauer Klaus
Published: September 2023

RRefreshing is assumed to reactivate the contents of working memory in an attention-based way, resulting in a boost of the attended representations and hence improving their subsequent memory. Here, we examined whether the refreshing-induced memory boost is an all-or-none or a gradual phenomenon. If the beneficial effect of refreshing on memory performance is due to the information being selected for refreshing (i.e., selection hypothesis), an all-or-none memory boost is expected to occur each time an item is selected for refreshing, with better memory performance for items that are selected more often. If, however, the beneficial effect of refreshing on memory performance is due to spending time in the focus of attention during refreshing (i.e., duration hypothesis), a gradual memory boost is expected, with the size of the memory boost being a direct function of how long the item has been the object of focused attention. To distinguish between these hypotheses, we instructed and guided the use of refreshing during retention through the presentation of cues, and varied the number of refreshing steps and their duration independently. The number of refreshing steps, but not their duration, had an effect on recall, in agreement with the selection hypothesis. However, some of the results were less robust than anticipated, indicating that the effect of instructed refreshing is constrained to certain task parameters.

Short Report on Maths For Life: A pilot study of the effectiveness of the Maths For Life programme for children with Down syndrome
Authors: Gilligan-Lee Katie Anne , McGuigan Karen , Snellgrove Holly , Van Herwegen Jo
Published: September 2023

Background: Beyond educational achievement, mathematics is essential for everyday living, e.g., telling the time, paying with money, using timetables. However, many children from neurodiverse populations fail to acquire basic mathematics skills in school. Aims: The aim of this study was to investigate if and how the Maths For Life programme, a new mathematical curriculum designed to help struggling learners, influences mathematics performance in children with Down syndrome. Methods and Procedure: Participants included 32 individuals with Down syndrome aged 5-to-24 years (Mage = 155 months, SD = 69.6). The study had a pre-post intervention design. The intervention group (n=15) completed the Maths For Life programme (administered by parent/guardian) in addition to their normal school classroom activities and the business-as-usual control group (n=17) completed their school mathematics classes only. Both groups completed a mathematics assessment pre/post the 4-month intervention period. Results: Although there were no differences for accuracy or non-attempt scores, the intervention group had higher independence scores compared to the business-as-usual control group. Conclusions and implications: The Maths For Life programme can help individuals with DS to improve their mathematical independence, evidence that supports further testing this programme in schools. Improving children’s independent application of mathematics is vital for everyday living.
The Emergence of the Academic Candidate. Evaluation as Textual Dramaturgy
Authors: Hamann Julian , Velarde Kathia Serrano
Published: September 2023

Our contribution sheds light on the dramaturgies of evaluation that precede candidate selection in academic organizations. The dramaturgies unfold across committee meetings, reviews, and reports that funnel the pool of candidates into a shortlist of prospective members. Because they are prolonged and not all stages involve copresence, the continuity and consistency of evaluative processes is a central dramaturgical problem. It highlights the constitutive role of written documents for the continuity and consistency of organizational evaluation processes. We marshal evidence from a comparative study on academic candidacy in two organizational settings: grantmakers, who select candidates for funding, and universities, who select candidates for professorships. Drawing on archived records produced in the context of research grant applications and professorial recruitments between 1950 and 2000, we distinguish two regimes of textual agency throughout the processes of evaluation: documents structure the process of candidate selection throughout dramaturgical stages, and they act as relays that transfer assessments of human actors across dramaturgical stages and time. In addition, by focusing on organizational access and showing how organizations make people before even hiring them, we draw attention to the emergence of a highly scripted dramatic figure in academic life: the candidate.
Zakres przedmiotowy reguły in dubio pro reo, czyli o możliwości rozstrzygania na korzyść oskarżonego niedających się usunąć wątpliwości prawnych (analiza kompleksowa)
Authors: Łukowiak Bartosz
Published: September 2023

Celem pracy jest analiza problemu zakresu przedmiotowego reguły in dubio pro, czyli rozstrzygnięcie trwającego od dekad sporu, czy wyrażony w art. 5 § 2 Kodeksu postępowania karnego nakaz rozstrzygania niedających się usunąć wątpliwości na korzyść oskarżonego dotyczy również wątpliwości prawnych, czy też powinno się z niego korzystać wyłącznie przy rozstrzyganiu wątpliwości o charakterze faktycznym. Artykuł ten stanowi pierwszą kompleksową analizę tego zagadnienia. Przedstawiono w nim zarówno wszystkie dotychczas wysuwane argumenty na rzecz każdego z przeciwstawnych poglądów, jak i wysunięto szereg własnych, niedostrzeganych dotąd argumentów. W pierwszej części tekstu analizie poddano m.in. charakter prawny dyrektywy in dubio pro reo, w tym zwłaszcza jej związek z zasadą domniemania niewinności. W dalszej jego części zbadano m.in. jaki wpływ na rozstrzygnięcie problemu przedmiotowego zakresu omawianej reguły mogły mieć kolejne nowelizacje przepisów prawa karnego procesowego, a także zestawiono tę dyrektywę z analogicznymi regulacjami z zakresu innych gałęzi prawa.

Mentha crispa L. is one of Vietnam’s most precious folk medicines and is also a spice used in many delicious dishes in Vietnam and around the world. The use of Mentha crispa L. leaf extract as a reducing agent for Ag+ ions to synthesize silver nanoparticles is discussed in this paper. Single silver nanospheres were dispersed in biological media and their sizes were controlled in the range of 20-80 nm. Factors affecting particle size and shape such as extract concentration, AgNO3 concentration, reaction time, and temperature were investigated to determine the optimal parameters for particle synthesis. The optical properties, dispersion, crystal structure, morphology, and sizes of silver nanoparticles were investigated through UV-Vis absorption spectroscopy, dynamic light scattering (DLS) measurements, X-ray diffraction, and transmission electron microscopy (TEM). The functional groups on the L.AgNPs were determined by Fourier-transform infrared (FTIR) transmittance spectra. The synthesised silver nanoparticles were used to treat methylene blue (MB) dye, the main component of dye wastewater, based on their photocatalytic properties. The results show that in the presence of L.AgNPs, the photodegradation efficiency of NaBH4 or H2O2 reducing agents is much higher, up to 95% of illumination.
Quests for the Power of the Poem (Forgetting the Power of the Past?)
Authors: Narbeshuber Lisa
Published: September 2023

The review article examines three innovative books: Poetry Unbound by Mike Chaser looks at how to account for poetry in the context of past and contemporary social media, while Why Poetry by Matthew Zapruder and Don’t Read Poetry by Stephanie Burt look at how and why to read poetry in our contemporary culture. The article begins with a discussion of the evolution of poetry from the 1910s when poetry was subject to dramatic technological changes and the rise of radical art movements, attracting new audiences. As poetry became more open-ended, intertextual, playful, and exploratory, the question of what constitutes (good or bad) poetry came to the fore. In their collective defence of poetry, Chaser, Zapruder, and Burt champion poetry, whether accessible or challenging, as popular, relevant, and socially beneficial. Though the three books’ readings of poetry and the examples used are often conventional, in a sense unconscious of their radical forebears, each book in different ways asserts the ongoing presence and power of poetry.
Digital Channels of Communication in the Promotion Function of a Tourist Destination – Tripadvisor Campaign Example of the Federation of Bosnia and Herzegovina
Authors: Šantić Marko , Jerković Darijo
Published: September 2023

Interactions and networking of social media in the tourism sector have experienced a very large expansion. This is certainly supported by the fact that the vast majority of today's tourists, through social networks - digital channels, search for, obtain and analyze information based on which they make decisions about choosing a destination, but also share and ex- change information about their impressions and experiences with others in already visited destinations. These were the main motives of the key actors in the Federation of Bosnia and Herzegovina who, at the instigation of the USAID Tourism Bosnia and Herzegovina Project, embarked on the first comprehensive digital campaign on social networks, the campaign of their chosen tourist destinations, in order to finally get out of the media "darkness", given that Bosnia and Herzegovina tourist destinations were not visible at all and were not adequately represented on the world tourist map. The campaign was realized on the world's largest tourist platform TripAdvisor. Be- fore the start of the campaign, the main objectives were set, the duration of the campaign was determined, the target markets were identified and the content was prepared in the form of attractive images, videos and promotional articles in four languages.
Development of the Tourist Market of Pčinja District – Strategic Approach
Authors: Stojković Radomir , Nikolić Ristić Dragana
Published: September 2023

In the paper, the authors deal with the issue of tourism development in the Pčinja district. The Pčinja district is located in the southeastern part of Serbia. Tourism came into the sphere of interest of the holder of the macroeconomic authority of this district as an alternative to industrial development. Namely, until ten years ago, the economic development of this district was based on industry, which was significantly devastated during the transition period. Since the industrial policy did not produce significant results, the need for alternative strategies for the growth and development of the Pčinja district was imposed. Using the SWOT method as an element of the situational analysis, the authors define the potential that the Pčinja district has in the tourism context. The authors complete the conceptualization of the tourist potential of the Pčinja district with a PEST analysis, as a type of external analysis, which sets strategic directions for the development and market research of this district in the tourist context.

Ownership and Organizational Solutions for Spas and Preservation of Health Tourism
Authors: Rajnović Ljiljana , Cico Snežana
Published: September 2023

This work aims to show the possibilities of organizing spas in the Republic of Serbia, bearing in mind the current privatization, the status and treatment of spas as goods of general interest and the importance of recognizing an adequate ownership solution in the future business of spas in Serbia. The authors consider world experiences, possible models of privatization and the impact on the function of spas, especially the extremely developed health segment - balneology, and of course, the preservation of natural healing resources, but also other possible contractual and ownership models of performing spa activities. In researching the period from 2012 to 2020, the authors found that privatization potentially improves the standards of spa infra- structure and increases the tourism potential of spas, but in some transition countries, the process has resulted in limiting the therapeutic potential of spas and reducing the state's ability to implement health policy. The authors recommend ensuring that spa activities are carried out by a safe shareholder, applying clear acceptance criteria, as well as to provide legal guarantees for access to spa services that are financed from public funds.

СТАТИЧНА ХАРАКТЕРИСТИКА ЗВАРЮВАЛЬНОЇ ДУГИ
Authors: Щетинін Сергій , Щетиніна Віра
Published: September 2023

Труби для газо- і нафтопровідних магістралей експлуатуються при високих тисках і низьких температурах, тому виготовляються з високоміцних сталей, при зварюванні яких трудно забезпечити ударну в’язкість зварних з’єднань. При електродуговому зварюванні труб значно зростає магнітне поле зварювального струму, магнітне дуття, електромагнітна сила відхиляє дугу в сторону меншого магнітного поля до обриву, довжина дуги зростає, стабільність процесу і формування швів порушується, що приводить до зниження ударної в’язкості зварних з’єднань. Природа зниження ударної в’язкості зварних Наука та виробництво2023 р. Вип. 25Машинобудування і зварювальне виробництво14з’єднань при зварюванні полягає в нагріванні метала шва і зони термічного впливу, тепловкладення, мікроспотворення кристалічної решітки, мікронапруг, щільності дислокацій, виникненні зварювальних напруг, зростанні міжатомної відстані та зниженні міжатомних зв’язків. Ефективним способом зниження енергії є підвищення швидкості зварювання, що зменшує погонну енергію, і напруги на дугі. Скорочення довжини дуги і напруги на дугі приводить до зниження діючої на дугу електромагнітної сили, підвищенню стабільності процесу, якості швів і ударної в’язкості зварних з’єднань. Встановлено, що статична характеристика UД = f(I) при lД = const відкритої дуги, що горить на стрічковому електроді, як і на дротяному, має U – образну форму). Падаюча характеристика при малоамперній дугі перетворюється на незалежну. Перехід до зростаючої характеристики відбувається для стрічкового електрода при нижчих значеннях струму (I = 90 А), ніж для дротяного (I = 200 А), що пояснюється припиненням зростання площі катодної плями на стрічці через обмеженість перерізу при нижчих значеннях струму порівняно з дротом . При однаковому значенні струму (I  90 А) дуга, що горить у відкритій атмосфері на стрічковому електроді, більше стиснена, ніж на дротяному. При односторонньому високошвидкісному зварюванні на низькій напруги на дугі зменшується енергія, зростає швидкість обертання і охолодження дуги, діаметр дуги зменшується, дуга концентрується, ефективність тепловкладення зростає, зона термічного впливу скорочується, забезпечується саморегулювання, рівновага, якісне формування швів і підвищення ударної в’язкості зварних з’єднань. Розроблено процес одностороннього високошвидкісного зварювання труб для газо-і нафтопровідних магістралей складовим електродом, який за рахунок зниження напруги на дугі забезпечує зменшення енергії, тепловкладення, зварювальних напруг, здрібнення мікроструктури, зменшення міжатомної відстані, збільшення міжатомних зв’язків і ударної в’язкості зварних з’єднань в 2 – 2,5 рази. Мінімум енергії – максимум ударної в’язкості зварних з’єднань.

У сучасних виробничих умовах на металургійних підприємствах одним з основних видів промислового транспорту залишається залізничний. Через старіння тягового рухомого складу виникає проблема перерозподілу ресурсів на позапланові ремонти, через збільшення яких знижується якість планових ремонтів. Низька ефективність і працездатність системи технічного обслуговування і ремонту, обумовлені надлишком ремонтних потужностей і падінням обсягів перевезень, яка призводить до зменшення витрат виділених безпосередньо системі. В наслідок цього утримання локомотивів в міру їх подальшої експлуатації при даній системі обслуговування і ремонту будуть поступово збільшуватися.

The results of studies on the influence of the species composition of herbage, the level of fertiliser, and growth stimulator Fumar on the density and botanical composition of plants are presented. The experimental part of the study was performed in the scientific laboratories of the Department of feed production, land reclamation and meteorology in the production division of the National University of Life and Environmental Sciences of Ukraine "Agronomic Research Station". The territory of the station is located in the Right-Bank Forest-Steppe and is part of the Bilotserkivsky agro-soil district. Experimental plots were laid on chernozems of typical low-humus large-dusty light loamy mechanical composition, which are characterised by a high content of nutrients. The climate of the region is characterised by unstable humidity and moderate temperature conditions. The average annual air temperature is 6-8°C. The annual amount of precipitation reaches 562 mm, during the growing season – 354-394 mm (63-70% of the annual norm), which falls unevenly throughout the year. Based on the conducted studies, it was identified that sown herbage is formed with a density of 686-1250 shoots per 1 m2 and a height of 58-148 сm. Alfalfa-cereal and cereal stands are denser than alfalfa ones. For the period from 1 to 3 years of use of herbage, the density of alfalfa shoots decreases, while that of orchard grass and smooth brome increases, and more intensively with the introduction of N60. During the first three years of use, grass stands are formed with the dominance of sown components with a share of alfalfa in single-species sowing of 85-98%, in alfalfa – cereal mixtures – 30-58%. For the period from the 1st to the 3rd year of use of alfalfa-cereal stands, the share of alfalfa decreases by 11-24%, and more intensively with the introduction of N60. In addition, between the two cereal components, there is a change of co-dominant – from meadow fescue to eastern fescue, eastern fescue to orchard grass, perennial ryegrass to smooth brome, like in the cereal stand, eastern fescue to smooth brome. In the 3rd year of use, ryegrass thins out, reducing the involvement rate to 5-14%

Winter barley is a valuable food, fodder, and technical crop. The purpose of the study is the establishing and developing of an economically and energetically feasible, adequate bioresource potential for the yield of winter barley grain, depending on its predecessors in Transcarpathia of Ukraine. Studies and calculations of the balance of available moisture in the soil showed that in the conditions of Transcarpathia, it is negative and ranges from 250 to 1210 t/ha, or 25-121 mm. The accumulation and effective use of available moisture in the soil depends on the amount of precipitation and its frequency, the alternation of crops in crop rotation (predecessors), the system of tillage, fertilisation, and the extent of how weeded the fields are. The largest reserves of available moisture in the soil during the sowing period of winter barley were after winter rapeseed and buckwheat, the smallest – after sunflower and, especially, corn for grain. During the autumn-winter period, the reserves of available moisture in the meter-deep soil layer were replenished by 21-35%, but the pattern, according to its predecessors, was preserved. The critical period of winter barley in terms of moisture occurs during earing – grain ripening. Predecessors of early harvesting periods (winter rapeseed and buckwheat) have a positive effect on the accumulation and preservation of moisture in the soil. Predecessors of late harvesting periods (corn for grain and sunflower) reduce the content of available moisture and its reserves by up to 18% compared to crops of early harvesting. On average, for three years, the highest yield of winter barley was after buckwheat and amounted to 5.9 t/ha, the lowest – after corn for grain and was at the level of 4.9 t/ha, which is 0.8 t/ha lower than the control option

Health literacy refers to individuals' ability to possess the necessary skills to make informed decisions about health-related issues. Individuals with adequate health literacy can read and understand written materials and communicate effectively with healthcare professionals. The purpose of this study is to examine the characteristics of graduate theses on health literacy in Türkiye and determine the direction of research topics. Since health literacy is associated with areas such as the preservation and improvement of individual and public health, and the reduction of healthcare costs, it is important to examine studies conducted in this field and conduct content analysis. In this study, content analysis was performed on theses (122 master's theses and 21 doctoral dissertations) with access permission on the YÖK National Thesis page. Theses that include the concept of health literacy in the fields of nursing, midwifery, and public health were included in the study. Parameters such as advisor title, page number, date of study, university, research design, sample group, objectives, results, and keywords were used in the research. The data were analyzed using SPSS and MS Excel, and descriptive statistics were applied. 2022 is the year in which the topic of health literacy has drawn interest the most since 2011, and studies have been concentrated in the field of nursing. Generally, descriptive, and descriptive-cross-sectional designs were used as research designs (30.8% and 35%, respectively). In these theses with different sample groups, mostly patients and adults were studied (25.9% and 25.2%, respectively). The objectives of the thesis studies generally focused on examining and correlating health literacy levels and diseases. There is also a tendency to determine the levels of health literacy and examine its impact on healthy living. Studies on health literacy for parents and caregivers were found to be less common than others. In the conclusion sections of the theses, it was emphasized that increasing health literacy levels is necessary for creating a healthy lifestyle and improving disease management. In addition, it was observed that studies that adapt scales and develop education materials/plans to increase health literacy are generally doctoral dissertations. Based on the examined studies, it is recommended that studies on health literacy for parents and caregivers be increased. It is also recommended that education materials used in studies be disseminated to more people to adopt a healthy lifestyle and improve disease management.

Authors: Tomchuk Olesya
Published: September 2023

The article is devoted to the generalization of the changes taking place in the labor market of Ukraine in the conditions of the war based on the analysis of its development trends, as well as the identification of challenges affecting the human resources of the economy. The relevance of the research topic is due to the fact that currently in Ukraine, business needs comprehensive and accessible information about the state and trends of the labor market in order to make sound management decisions in the field of personnel support and develop appropriate measures in response to the challenges experienced by the labor market in the conditions of martial law. The research was conducted using the information base of the State Employment Service, as well as on the basis of processing the results of surveys conducted by sociological groups and consulting companies. The dynamics of the unemployment rate in Ukraine and the load on 1 vacancy were analyzed, special attention was paid to the category of internally displaced persons (IDPs) in the labor market. It was determined that IDPs are a potential source of solving the problem of business staffing in wartime conditions. The trends of the labor market of Ukraine in the conditions of war, which take place from the side of labor supply and demand, are summarized. The challenges of wartime, which the labor market of Ukraine feels most acutely, are defined as follows: settlement of the regional imbalance of the labor force; settlement of the professional and qualification imbalance in the labor market, in particular through the formation (in the updated system of professional education) of jobseekers with the skills required by the economy; promoting the integration of IDPs into the labor market of host communities; investing in the creation of new jobs with decent and inclusive working conditions; stimulation of effective employment of women and youth; spread of new forms of employment and support of self-employment.

Published: September 2023

Local budgets are one of the important components of the national budget system and the country as a whole. They have a significant impact on the solution of national tasks of an economic and social nature, including: financing of industry, energy, agro-industrial complex, infrastructure development, as well as the spheres of health care, education and social protection. The full-scale Russian invasion became a global challenge of modern times for Ukraine, which affected all economic processes of both the country and each individual component. Due to the military aggression of the Russian Federation, local budgets faced the problem of not receiving planned revenues, which became a threat to the implementation of the powers defined by the law. The article is devoted to the topical issues of determining the current state and peculiarities of the implementation of local budgets in the period of economic challenges. Implementation of the state budget for 2022 was analyzed. The growth of incomes, expenses and deficit is determined. The reason for this was military aggression, because foreign grants played a significant role in the formation of budget revenues in 2022, and the largest percentage of financial resources was directed to protection and defense. On the example of Lviv Oblast, the structure of local budget revenues and expenditures was analyzed, and changes in their volumes were considered. Attention is focused on the items of income and expenses that have experienced the greatest reduction and the reasons for the negative dynamics are investigated. Expenditures of local budgets most vividly reflect their importance in the functioning of the local economy, the maintenance of social and cultural objects, the implementation of investment policy, the implementation of social protection of the population, and environmental protection. They reflect the same socio-economic relations as the State budget expenditures, but at the local level and taking into account regional features. It is also highlighted that, despite difficult forecasted circumstances, local self-government bodies are working to attract and increase financial resources, create new jobs, and grow revenues to the budget. This, in turn, will make it possible to quickly adapt to new challenges and ensure the proper level of performance of assigned powers.
