THE 21st CENTURY IN ENGLISH WORDS OF THE YEAR: FLEXIBILITY OF MODERN ENGLISH VS LINGUISTIC CONCEPT OF WORD
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Belova Alla D.
Published: February 2025

The article explores words of the year (WOTY) announced by the Oxford English Dictionary, Cambridge Dictionary, Merriam Webster Dictionary, and American Dialect Society in terms of the linguistic concept of Word. WOTY poses questions about the changes in the requirements for a word as the basic unit of language that spans orthography, morphology, word formation, naming, categorization, semiotics, and semantics. The list of 77 English WOTY that label the 2001-2023 period is based on two major varieties of English (British English and American English) and, thus, mirrors the anglo-centric vision of the world, burning issues of the 21st century, global and national events. In many cases, WOTY is of historical value as it encapsulates vital human problems. Linguistically, WOTY reveals enormous changes in the English language and the factors that trigger the immense popularity of these words. Many prominent linguists and philosophers of the 19th-20th century made a significant contribution to the linguistic concept of Word, describing the correlation between a word and a concept or notion, a word and a part of speech, structural, semantic, and syntactic aspects of Word, its uninterruptability and positional mobility. Due to the wide diversity of languages in the world, the characteristics of words are not universal. Unprecedented flexibility of English, new trends in spelling and word formation, specific word coinages in English of the 21st century make pretty obvious the fact that traditional criteria for a word are becoming lenient. Suffixes -ism and –ussy, two-word expressions as WOTY prove the Word borders become less tightened. Hashtags neutralize word spacing as a crucaial parameter in the distinction of words and question the correlation of a word and a part of speech. Pictorial elements (emojis) and hashtags emphasize the fusion of alphabetical and non-alphabetical symbols in the domain of English-language communication. Penetration of non-alphabetical scrips (#, emoji, numerical symbols) into the English language, including WOTY, reflects the impact of video gaming, text messaging, ICT, and digital technologies on the English of young generations.

Authors: Kryukov Alexey , Maryushin Leonid , Sennikova Olga , Semochkin Gleb
Published: February 2025

BACKGROUND: Studies in the field of heat transfer in heat exchange equipment show significant deviations in calculations when the thermophysical properties of materials are assumed to be averaged. This creates problems in design and reduces the efficiency of heat exchangers.
AIM: Devise and implement heat transfer models that account for variations in temperature within the thermal properties of materials, with the goal of enhancing the precision of heat transfer predictions and optimizing the design of heat exchange systems.
METHODS: The study utilized numerical analysis of heat transfer considering temperature variations of thermophysical properties. Heat carrier mobility and relaxation models were applied. The study included the analysis of thermal conductivity coefficient, specific heat capacity, density, average velocity of heat carriers, their free path length and relaxation time. The evaluation methods included mathematical modeling and numerical calculations.
RESULTS: The analysis showed that the use of models that take into account temperature dependencies significantly improves the accuracy of heat transfer calculations. The heat transfer coefficient, carrier mobility and relaxation time were found to depend significantly on temperature. Qualitative changes in the mobility of thermal carriers as a function of temperature and the aggregate state of the material were determined.
CONCLUSION: The proposed models of mobility and relaxation of thermal carriers allow to predict heat transfer more accurately, which improves the design of heat exchangers and increases their efficiency in industry. These models can be used for further research and optimization of heat transfer systems.
Kinematic Source Modeling Using Radiation-Corrected Empirical Green’s Functions in Waveform Inversion
Authors: Shibata Ritsuya , Aso Naofumi
Published: February 2025

Waveform inversion is an effective way to estimate the spatiotemporal slip distribution and directions, known as the source process. However, this method has limitations in its applicability due to the availability of a velocity structure with sufficient resolution. In this study, to expand the applicability of the waveform inversion, we proposed and tested a new waveform inversion method based on the empirical Green’s function (EGF) approach with radiation correction. This new method is advantageous for estimating slip directions with a single EGF event. We verified the performance of the new inversion method using synthetic tests with theoretical waveforms. We confirmed that the distribution of the assumed slip can be reproduced effectively using this new inversion method, reproductivity which is superior to the conventional EGF approach. Larger location and mechanism differences between the EGF and target events caused the worse reproductivity of the slip model. We then analyzed the source processes of crustal earthquakes in Japan to investigate the applicability of the new method for real data. Consequently, we obtained source models with a better waveform fitting with a variance reduction of 40%. The uncertainty in the inversion results was also investigated using a bootstrapping test. The results suggest that a larger slip can cause less variety in the slip amount and direction. We investigated the inversion stability using various candidate EGF events. The slip distributions for each candidate EGF event had a common characteristic for most cases. However, the station coverage sometimes affected the inversion results. This new inversion method can contribute to a broader understanding of the mechanisms of fault rupture growth in kinematics.

Published: February 2025

Pongamia pinnata L. Pierre is a multipurpose oil tree species, a source of renewable biofuel, in addition to being a recuperator of degraded soils due to its capacity to fix nitrogen. The most common form of propagation is through seeds, but there is little information available on its vegetative propagation, with asexual propagation being essential to maintain the characteristics of the mother plant and avoid variability. The objective of this work was to evaluate the incidence of substrate type, rooting hormone application and time of year on the vegetative propagation capacity of P. pinnata by means of root cuttings. The experiment was carried out in the Forest Nursery of the Faculty of Agricultural Sciences, National University of Asunción. A completely randomized design with factorial arrangement (3×2×2) was used, composed of 3 types of substrates, 2 times of the year, with and without application of IBA hormone. The variables evaluated were: percentage of survival and rooting, number of rootlets, rootlet length and rooting index. The data were subjected to analysis of variance (ANOVA) and in cases where significant differences were found, means were compared using Tukey's test at 5% probability. The results indicate that Pongamia cuttings are not significantly influenced by the application of the IBA hormone and the type of substrate. However, they are significantly influenced by the time of year, with spring-summer being the best time for propagation by root cuttings, as demonstrated in this study.

Background: The hydroalcoholic extract derived from Curcuma caesia (CCHE) is recognized for its traditional use and well-established medicinal properties, often prescribed for the treatment of various ailments like skin cancer. Global trends favoring the utilization of non-toxic plant-based products, particularly those aligned with conventional medicinal practices and considering the reliance of developing countries on herbal remedies for primary healthcare. Methods: This study aims to investigate the in-vitro cytotoxic effects of CCHE on the SK-MEL-28 human skin cancer cell line (specifically, skin melanoma) through MTT assays. The evaluation revealed that the hydroalcoholic extract of CCHE exhibited a notable inhibitory effect on the SK-MEL-28 cell line, with a percentage inhibition of 80.29% observed at lower concentrations (25 g/ml) and reaching 92.65% at higher concentrations (400 g/ml). Result: These findings suggest that CCHE, herein referred to as CCHE (Potentiated Hydroalcoholic Extract), instigated a mechanism leading to cell arrest, thereby impeding the proliferation of cancer cells. In comparison to conventional medicines, the observed inhibitory effect of CCHE underscores its potential as a cytotoxic agent against human skin cancer cells.

Uprawnienia podatnika w zobowiązaniu podatkowym
Authors: Nowakowski Maciej
Published: February 2025

Przedmiotem badań w niniejszej monografii były uprawnienia podatnika będące podstawą do realizacji przysługujących praw, zawartych w normach prawnopodatkowych. Nadrzędnym celem badawczym było przyjęcie klasyfikacji uprawnień podatnika w zobowiązaniu podatkowym. W stosunku prawnym zobowiązania podatkowego, podstawowym przedmiotem rozważań i zainteresowania doktryny prawa podatkowego jest obowiązek podatkowy, stanowiący punkt wyjścia przy ustalaniu wysokości zobowiązania podatkowego. Natomiast uprawnienie rozpatruje się bardziej w odniesieniu do organu podatkowego, który w połączeniu z przyznaną ustawowo kompetencją, uprawniony jest do żądania spełnienia świadczenia podatkowego. Zapomina się jednak, że w ramach stosunku prawnego zobowiązania podatkowego, ustawodawca wyraża poprzez normy prawa podatkowego pewne sytuacje, które stanowią o możności przyjęcia odpowiedniego modelu zachowania również przez podatnika. Stanowiło to podstawę do przyjęcia założenia, że w odniesieniu do podatnika, ustawy podatkowe wyrażają również pewne uprawnienia. Istnienie uprawnień podatnika jest skutkiem przyjęcia konstrukcji stosunku zobowiązaniowego w prawie podatkowym, jednakże skoro ustawodawca w definicji zobowiązania podatkowego nie użył określenia uprawnienia, a częstokroć z niego korzysta w przepisach prawa podatkowego, należało dokonać uporządkowania terminologicznego w tym obszarze i wskazać, na podstawie jakich kryteriów wyodrębnia się badane zagadnienie. Poprzez dokonanie klasyfikacji na uprawnienia główne oraz uznaniowe ustalono i zbadano uprawnienia podatnika na etapie powstawania, odpowiedzialności, zabezpieczenia oraz wygaśnięcia zobowiązania podatkowego. W pracy postawiono hipotezę, że realizacja treści uprawnienia związana jest z przyjętą w pracy klasyfikacją, a nie samym przyjęciem odpowiedniego modelu zachowania się przez podatnika, polegającym wyłącznie na wykonaniu określonej czynności. Hipoteza obejmowała także stwierdzenie, że w procesie stosowania prawa podatkowego uprawnienie podatnika na każdym etapie zobowiązania podatkowego przyjmuje zróżnicowaną formę oraz zakres przedmiotowy, będący determinantem treści uprawnienia.

Przedmiotem badań było prawo podatkowe, ze szczególnym uwzględnieniem ustawy Ordynacja podatkowa, a także po części szczegółowe prawo podatkowe. Realizacja celu monografii nie byłaby możliwa bez analizy utrwalonych już poglądów doktryny, jak i zbadania orzecznictwa.

Pracę przygotowano na podstawie metody dogmatyczno-prawnej. Ponadto w pracy zawarto rozważania teoretycznoprawne. W rozważaniach nad zagadnieniem istoty uprawnienia posłużono się metodą historyczno-prawną, która pozwala na określenie genezy uprawnienia, a także wskazanie na podstawy źródeł uprawnienia w Konstytucji RP.

Published: February 2025

Este artigo tem o objetivo de analisar como a educação inclusiva é representada no Processo de Bolonha. Apoiado no conceito de conjunto educativo (Robertson; Dale, 2014), foi realizado um estudo documental por meio da análise do grupo de trabalho da Dimensão Social entre os anos de 2014 e 2024, recorte temporal desta pesquisa. Este grupo é responsável por promover políticas de equidade e inclusão na educação superior na Europa. Os resultados apontaram que não tem havido um equilíbrio entre as políticas que compõem o conjunto educativo do Processo de Bolonha. As políticas do grupo de trabalho analisado possuem caráter homogeneizante, sem distinguir seu público alvo, por dificuldades socioculturais próprias que a Europa tem enfrentado na última década, marcada por dificuldades econômicas, guerras e a crise da imigração. As questões ligadas ao mercado da educação têm tido uma evolução maior e a dimensão social não tem ocupado o mesmo espaço nos debates dos encontros avaliativos.

This study aims to develop an investigative model of repurchase intention from a multidisciplinary service marketing science perspective, focusing especially on conventional and digital franchise retail services. This is supported by psychological consumer purchasing behavior to deepen the analysis of customer repurchase decisions for multinational franchise retail food and beverage products in Indonesia. Following the boycott movement against certain foreign-brand food and beverage goods, the impact of religious beliefs, hostility, and the perception of the country of origin define this process. A causal/explanatory survey was employed as the research method. Participatory observations, interviews, and questionnaires with 220 respondents were used as primary data-gathering methods. These were distributed both digitally and conventionally. Google Form in all randomly selected public and private university analysis units in Indonesia. The observation unit (respondent) used a convenience/accidental sampling technique. The analytical tool employed Lisrel version 88.0. The findings reveal that Islamic religiosity, consumer animosity, and country of origin affect repurchase intention. This original research can generate specific and relevant findings for the Indonesian market context, which companies can use to design more effective marketing, brand management, and product development strategies. This will help companies better understand their customers’ preferences and needs, as well as build stronger relationships with consumers.

Background:

The impact of radiation exposure on cataracts and hand skin cancer in orthopaedic and spine surgeons remains understudied. This study aimed to investigate the prevalence of cataracts and chronic hand inflammation in orthopaedic and spine surgeons and to assess their association with radiation exposure.

Methods:

A cross-sectional analysis was conducted on orthopaedic and spine surgeons attending the 38th Annual Meeting of the Neurospinal Society of Japan or the 31st Annual Meeting of the Japanese Society for the Study of Low Back Pain. Cataractous changes were categorized into none, lens micro-opacity, or cataracts and were detailed alongside the prevalence of chronic hand inflammation, which included longitudinal melanonychia and hand eczema. Participants were divided into quartiles according to hand-exposure opportunities in the operating and fluoroscopy rooms in 2022. Prevalence ratios and 95% confidence intervals (CIs) of chronic hand inflammation in the upper quartiles relative to the first quartile were calculated using modified Poisson regression adjusted for potential confounders.

Results:

The median work experience of the 162 participants was 23 years, and the median number of hand-exposure opportunities was 70 (interquartile range [IQR], 20 to 123) in the operating room and 20 (IQR, 0 to 60) in the fluoroscopy room. The prevalence of cataracts was 20% (32 participants), and the prevalence of cataractous changes, including lens micro-opacity, was 40% (64 participants). Chronic hand inflammation was present in 62 participants (38%), of whom 52 had longitudinal melanonychia and 23 had hand eczema. The adjusted prevalence ratios of chronic hand inflammation relative to the lowest quartile of hand-exposure opportunities in the operating room were 0.91 (0.50, 1.66) for quartile 2, 0.72 (0.41, 1.25) for quartile 3, and 1.56 (0.97, 2.50) for quartile 4. For fluoroscopy room exposure, the adjusted prevalence ratios were 2.31 (1.16, 4.58) for quartile 2, 2.03 (1.00, 4.09) for quartile 3, and 2.94 (1.51, 5.75) for quartile 4.

Conclusions:

This study highlighted substantial cataractous and chronic hand inflammatory changes in spine surgeons, indicating indirect and direct radiation exposure effects. Therefore, radiation safety and protective measures must be emphasized. Comparative studies with other populations and longitudinal observations are required to better understand the effects of radiation on health.

THE EFFECTS OF TWO RECENT HURRICANES ON FORAMINIFERAL ASSEMBLAGES AND SEDIMENTS OF A WAVE-DOMINATED, MICROTIDAL BARRIER-ISLAND SYSTEM, NORTH CAROLINA, USA
Authors: Culver Stephen J. , Mallinson David J. , Allen Cody , Brown Colby , Shmorhun Nina Maria-Elena , Buzas Martin A.
Published: February 2025

We investigate whether sediment grain-size and foraminiferal data may be used to recognize hurricane activity in sandy barrier island sediments, specifically on Bear Island, North Carolina, USA. Eighteen locations were sampled in 2016 following a five-year quiescent interval. The same sites were resampled in 2018 following Hurricane Florence, and again in 2019 following Hurricane Dorian. Samples were used to test the hypothesis that different sediment sources and transport directions were activated by each storm, thus leading to varying foraminiferal assemblages, and changed sediment characteristics in barrier island environments. The effects of hurricanes Florence and Dorian on sediments and foraminifera of barrier island environments proved to be different and complex. Hurricane Florence reduced environmental distinction and Hurricane Dorian had a lesser effect likely due to its lower energy and different track. Thus, the contrasting energy of these hurricanes, their tracks, and wind directions, were important determinants of changes to the barrier islands that took place in 2018 and 2019. Each hurricane has its own characteristics and subsequent effects on barrier island sedimentological and micropaleontological characteristics. Recognition of discrete episodes of hurricane-driven onshore transport in the sand-rich part of the stratigraphic record of a barrier island system adjacent to a sediment-starved shelf is unlikely.

Objetivo: Estimar la asociación entre el autoreporte de déficit visual y dependencia funcional en adultos mayores pertenecientes a 12 comunidades altoandinas del Perú. Materiales y Métodos: Estudio de análisis secundario de tipo observacional analítico transversal. Se incluyeron 453 adultos mayores de 60 años de 12 comunidades altoandinas. Para el análisis bivariado se empleó la prueba de Chi-cuadrado para las variables cualitativas y la prueba de T-student para las variables cuantitativas (IMC, media de edad). Para el análisis multivariado se utilizaron 3 modelos de regresión lineal de Poisson con función de enlace logarítmico y varianzas robustas para desenlaces dicotómicos, se reportaron razones de prevalencias crudas y ajustadas con sus respectivos intervalos de confianza (IC 95%). Resultados: Se analizaron los datos de 453 adultos mayores de comunidades altoandinas. La prevalencia de dependencia funcional fue de 70% con una media de edad de 74 años. 156 adultos mayores con dependencia funcional presentaban déficit visual (75.7%, p=0.005). En el modelo crudo y ajustado de acuerdo al sexo, los participantes con déficit visual tuvieron 1.19 (IC 95%, 1.05-1.34, p=0.005) y 1.22 (IC 95%, 1.02-1.28, p=0.027) veces más probabilidades de presentan dependencia funcional respectivamente. Se encontraron los factores asociados en el modelo 2, como la polifarmacia, edad, y trastorno neurocognitivo. Conclusiones: En los adultos mayores de comunidades altoandinas, la presencia de déficit visual está significativamente asociada con una mayor probabilidad de presentar dependencia funcional.

Published: February 2025

Objetivo: Determinar la asociación entre la adherencia a recomendaciones para el manejo de pacientes adultos mayores (AM) y el edadismo de médicos de especialidades quirúrgicas. Materiales y métodos: El presente estudio transversal y observacional evaluó la adherencia a recomendaciones para el manejo de AM de 157 cirujanos en las fases operatorias: pre, intra y postoperatorio. Se utilizó la escala "Proposed Geriatric Competencies for the Surgical Specialties" para determinar la adherencia y la escala "UCLA-Geriatric Attitude Scale" para el edadismo. Resultados: Se halló que las actitudes negativas hacia el cuidado de pacientes adultos mayores influyen en mayor proporción en la adherencia a las recomendaciones para el intraoperatorio. Además, los médicos que recibieron capacitaciones en geriatría mostraron una mayor adherencia en todas las fases quirúrgicas. Conclusiones: En conclusión, el edadismo en médicos de especialidades quirúrgicas puede disminuir la calidad de manejo de AM en la fase intraoperatoria, pero la formación geriátrica de los mismos durante el proceso de especialización mejora la adherencia a las recomendaciones en las diferentes fases operatorias. Por lo tanto, es sumamente importante promover las capacitaciones en geriatría para optimizar la atención quirúrgica en este grupo etario de la población.

Published: February 2025

Introducción: La contaminación ambiental por residuos plásticos (RPs) es un asunto alarmante acrecentado por la falta de reciclaje y mala gestión. La odontología no es ajena al problema debido al uso habitual de materiales plásticos de un solo uso, que por un lado evitan las infecciones cruzadas, pero necesitan un uso controlado. Objetivo: Cuantificar los RPs generados en la atención clínica de pregrado de un centro odontológico universitario privado en Perú. Material y Métodos: Este estudio descriptivo transversal determinó la cantidad de RPs de cinco áreas de clínica y una de radiología producidas según el tipo de atención (n = 7) y procedimiento (n = 21) observado en 40 unidades dentales (UDs) durante 19 días en 2023. Los RPs se caracterizaron en tipo, composición, número y peso. Los resultados se proyectaron por año y se analizaron con la prueba de Kruskal-Wallis usando el software R con P < 0,05.

Several studies have successfully detected SARS-CoV-2 in air samples; however, in most of these, the focus was on validating the air collection method, and there was no report on the development of a virus-detection method. In this study, to detect viruses in air samples more sensitively than conventional detection methods, we applied COPMAN, a highly sensitive virus-detection method using wastewater samples, to air samples to develop COPMAN-Air. Briefly, with this method, the extremely low amount of viral RNA in air samples is efficiently detected via three reaction steps: RT, preamplification, and qPCR, as with COPMAN. We evaluated COPMAN-Air using samples from a fever clinic for COVID-19 patients. COPMAN-Air demonstrated a higher detection rate of viral RNA compared to conventional methods: 22 (95.7%) vs. 14 (60.9%) out of 23 samples. Additionally, a positive correlation (r=0.70) was found between the amount of viral RNA detected by COPMAN-Air and the number of confirmed COVID-19 cases, suggesting that COPMAN-Air could estimate the number of SARS-CoV-2-positive individuals in a given space based on the quantitative values of SARS-CoV-2 RNA in air samples. Surveillance systems for pathogens in the air using COPMAN-Air are expected to be valuable for assessing the number of infected individuals and for the implementation of public health measures.

Scorpion stings are a significant public health concern, particularly in endemic regions, due to their potential to cause severe envenomation with fatal complications. We present the case of a 3-year-old male who developed fulminant myocarditis following a scorpion sting. The patient was admitted in a critical state with cardiogenic shock, acute pulmonary edema, and multiorgan failure. Despite aggressive management, including mechanical ventilation, inotropic support, and intensive care interventions, the patient succumbed to progressive cardiac and systemic complications. This case underscores the severity of scorpion envenomation, the rapid progression of cardiac toxicity, and the importance of early, intensive management. Preventive measures and enhanced critical care protocols are crucial in endemic regions to reduce morbidity and mortality associated with scorpion stings.

Published: February 2025

Place-making is a multifaceted process that imbues physical spaces with cultural, social, and economic significance, resulting in environments that promote distinct identities. Kumartuli, a historic artisanal neighborhood in Kolkata, exemplifies this process with its unique blend of spatiality, socio-ritual practices, and cultural heritage.Known for its centuries-old idol-making customs, Kumartuli is a vibrant place where innovation and heritage coexist, shaping the identity of its artisanal community and contributing to Kolkatas cultural landscape. This paper examines the congruence of idol-makers adaptation to place-making processes and visitors, particularly photographers, perceptions of Kumartulis spatiality.Fieldwork was conducted in September when idol-making activities were at their peak, and included unstructured interactions with ten practicing idol-makers as well as informal discussions with visiting photographers. Thematic data analysis reveals that Kumartulis dense network of narrow lanes, clustered studios, and riverside accessibility shape artisanal craft while also contributing to the performative and symbolic dimensions of place-making. The findings show how the artisanal fraternity balances tradition and innovation, adapting creatively to spatial constraints while preserving their socio-ritual practices and cultural identities.This study emphasizes Kumartulis functionality as a site of cultural production and identity negotiation by placing it within theoretical frameworks of place-making, postcolonial urbanism, and informal spatial networks. It adds to conversations about urban informal settlements by highlighting their value as hubs of heritage, creativity, and perseverance in a contextuality of urban neighborhood that is experiencing rapid transformation.
Rechtliche Fragen der kommunalen Gebietsreform in Deutschland
Authors:   European Constitutional Law Association, Kay Inkook
Published: February 2025

Gebietsreform der deutschen Kommunalverwaltungen erscheint als Teil einer Verwaltungsreform, die die organisatorischen, rechtlichen, personellen und finanziellen Strukturen der Verwaltung planmäßig verbessert. Während frühere Gebietsreformen durch Bevölkerungsrückgang oder die Wiedervereinigung bedingt waren, zeigen sie sich im 21. Jahrhundert als Modernisierungsstrategie. Daher muss die Gebietsreform darauf ausgerichtet sein, Nutzbarkeit, Bequemlichkeit und Zugänglichkeit durch verbesserte Effizienz und Leistungsfähigkeit der kommunalen Verwaltung zu steigern.
Gebietsreform qualifiziert als ein Eingriff in die verfassungsrechtlich garantierte kommunale Selbstverwaltung. Daher müssen bei der Bestimmung der Notwendigkeit einer Gebietsreform sowohl die Ziele der Verwaltungsreform als auch der demokratische Wille der Bürger berücksichtigt werden. Die Anhörung ist das wichtigste demokratische Beteiligungsverfahren bei Gebietsreformen, das es den betroffenen Kommunen ermöglicht, ihre Ansichten zu den für sie wichtigen Fragen zu äußern. Da Gebietsreformen erhebliche Auswirkungen auf die regionale und kulturelle Verbundenheit sowie die Identität der Gemeindebewohner haben, ist die Sicherstellung demokratischer Legitimität durch Bürgerentscheide von großer Bedeutung. Gebietsreformen ergeht durch Bundesgesetz, das der Bestätigung durch Volksentscheid bedarf und der Gesetzgeber muss die Ziele der Reform möglichst konkret vorschreiben. Insbesondere muss geprüft werden, ob das öffentliche Interesse an der Gebietsreform ausreichend in der institutionellen Garantie der kommunalen Selbstverwaltung begründet ist, ob die Abwägung mit den Bürgerrechten verhältnismäßig ist und ob die Forderung nach Gleichbehandlung zwischen den Kommunen erfüllt werden kann. In Deutschland entwickelt sich die Gemeinwohlzielsetzung der Gebietsreformgesetze dahingehend, dass sie nicht auf einer abstrakten Ebene verbleibt, sondern konkrete Begründungen und Beurteilungen für das öffentliche Interesse liefert.

Published: February 2025

By extracting bioactive compounds from plant materials, scientists study their chemical composition, biological activity, and potential applications. Plant extracts can be used in functional foods and as additives that improve the quality and safety of products. New extraction methods offer sustainable and efficient technologies. This research featured maceration, ultrasonic extraction, microwave extraction, solvent extraction under pressure, and supercritical fluid extraction, as well as their advantages and disadvantages. The method of supercritical CO2 extraction made it possible to obtain target components from amaranth seeds. The input variables included the degree of fractionation and operating pressure while the temperature was a constant parameter. The degree of fractionation proved to be the key factor for the yield: the lower the fractionation, the higher the extract yield. A higher pressure increased the yield in the case of low particle dispersion. At 300 atm, the extract yield was lower for fractions of 0.31–0.56 and 0.16–0.31 mm than at 200 atm. The total extract yield ranged from 10.00 ± 0.20 to 18.20 ± 0.20% at 100 atm, from 10.54 ± 0.20 to 19.45 ± 0.20% at 200 atm, and from 11.64 ± 0.20 to 16.31 ± 0.20% at 300 atm. The amaranth extract demonstrated good prospects as an additive to vegetable oils, spreads, and cheeses.

Objective(s): This study aimed to evaluate the impact of Mother-Baby Friendly Facility (MBFBF) accreditation on midwifery staff's perceptions of obstetric mistreatment. The hypothesis tested was that MBFBF-associated training and policy changes would improve awareness and reduce tolerance toward mistreatment practices during childbirth.
Study Design: This single-center observational pre-post study was conducted in the obstetrics and gynecology unit of a tertiary hospital. Data collection occurred before and after MBFBF accreditation, granted in November 2024. The study included 122 midwifery staff with at least one years of clinical experience before accreditation. Perceptions of obstetric mistreatment were assessed using the Turkish version of the Perception of Obstetric Violence in Students Questionnaire (PercOV-S Q). Statistical analyses included Wilcoxon signed-rank, Mann-Whitney U, and Kruskal-Wallis tests to evaluate changes in scores and subgroup differences.
Results: Significant improvements were observed in perceptions of mistreatment, with overall PercOV-S Q scores increasing from 95.50 (87.00–107.00) pre-intervention to 110.50 (83.50–129.00) post-intervention (p = 0.027). Key areas of improvement included informed consent (Q1: p < 0.001), privacy (Q2: p < 0.001), and respectful communication (Q3: p = 0.017). Subgroup analysis showed statistically significant differences in five selected questions (p < 0.001), while other areas showed trends toward improvement.
Conclusion(s): The MBFBF accreditation process and associated training significantly enhanced midwifery staff's awareness of obstetric mistreatment, aligning with international guidelines. These findings underscore the importance of structured education and institutional reform in fostering respectful, patient-centered care. Expanding MBFBF accreditation programs globally could contribute to reducing obstetric mistreatment and improving maternal health outcomes.
