Habitabilidad: condición clave en el diseño urbano para transformar el entorno construido-habitado
Authors: Macías-Ángeles Yatzin Yuriet , Méndez-Ramírez José Juan
Published: January 2025

Este artículo tiene como objetivo aproximar la interrelación entre la habitabilidad y el diseño urbano como una clave fundamental para la transformación del entorno construido-habitado, en tanto lo construido refiere a las condiciones físicas y lo habitado a las no físicas observables en los aspectos socioculturales dentro del entorno de una cultura en el tiempo. Para ello, se hace una revisión documental multidisciplinaria y retrospectiva, con el fin de identificar elementos conceptuales que contribuyen en la comprensión de dicho binomio. Se parte de la búsqueda del significado de habitar, concepto que le confiere origen y sentido a la habitabilidad; mientras que el diseño urbano al ser un campo tridimensional con visión holística se reconoce a sí mismo como un medio transformador multidisciplinario e interdisciplinario, que extrae su legitimación de teorías de diversas raíces intelectuales para comprender las condiciones físicas y las no físicas. Se concluye que el binomio habitabilidad-diseño urbano resulta fundamental para contribuir en el diseño, construcción y calidad de los entornos urbanos, promoviendo la convivencia, salud, calidad de vida y espontaneidad de sus habitantes.

El análisis se realiza a partir de las características perceptuales, ubicación, tipo deregla social que se demanda seguir, y si en ellas se establecen macro o metacontingencias paraincentivar comportamientos urbanos responsables (CUR). Los resultados reflejan que las señalesestán orientadas a la seguridad, higiene, movilidad, cuidado del ambiente y del patrimonio; difierenen cuanto al tipo de beneficio o sanción que anuncian por seguir o no la regla; no siguen un patrónunificado en su diseño, y son pocas las que enuncian el beneficio colectivo por ajustarse a las reglas.Se discute la importancia para las administraciones de la ciudad del diseño de una señalizaciónorientada hacia el seguimiento de reglas que promueven CUR dentro de un sistema integrado quedefina sus características perceptuales, le informe a la ciudadanía sobre los resultados productodel seguimiento de las reglas de convivencia mediante macro y metacontingencias y planifique suubicación dentro del espacio urbano.
Acerca de lo sensible en la condición ontológica del objeto arquitectónico: lo efímero como mediador
Authors: Orejuela-Branch Katherine
Published: January 2025

Este artículo explora la sensibilidad del objeto arquitectónico con una perspectiva ontológica, buscando un diálogo entre sus aspectos subjetivos y objetivos que trascienda su concepción y materialización. A través de un enfoque fenomenológico, los resultados se organizan en tres categorías: 1) significado de la sensibilidad; 2) sensibilidad en el plano ontológico del objeto, y 3) sensibilidad en relación con la ontología del cuerpo. La discusión revela que lo efímero actúa como una tensión entre lo subjetivo y lo funcional, otorgando al objeto una dimensión poética que facilita una conexión significativa con el sujeto. Se concluye que la experiencia arquitectónica es un acto trascendental, que involucra sensorial y emocionalmente al sujeto, enriquecido por elementos como la metáfora, la tectónica, el juego de luz y espacio, y la memoria.
Reflexiones en torno a la enseñanza de la arquitectura y el urbanismo en Colombia. Conversaciones con Pedro Buraglia Duarte y Olavo Escorcia Oyola
Authors: Ávila-Gómez Andrés , Montaño-Bello Alfredo
Published: January 2025

Las dos entrevistas que componen esta cuarta serie nos ofrecen nuevos elementos que, sumados a los testimonios de los ocho entrevistados reunidos en las series anteriores, corroboran el eco que Mayo del 68 tuvo en las facultades de arquitectura colombianas.
El testimonio de los arquitectos Pedro Buraglia y Olavo Escorcia nos deja entre otros temas a destacar, el relato en torno a la importancia que las redes académicas latinoamericanas han tenido desde los años 1980 en la circulación de conocimiento; aunque nos plantea también una serie de interrogantes sobre las razones -¿falta de apoyo institucional; temas carentes de interés en el medio académico?- que han conducido a que la gran mayoría de dichas redes tengan una vida relativamente corta y desaparezcan del panorama académico.

Published: January 2025

Neonatal sepsis (NS) is highly likely to cause death; however, early diagnosis of NS is still a great challenge. This study aimed to determine the diagnostic values of IL-6, IL-8, and serum amyloid A (SAA) in NS patients. C-Reactive protein (CRP), procalcitonin (PCT), interleukin (IL)-6, IL-8, and SAA were detected in 120 infants with NS (60 premature infants [NS-PIs] and 60 term infants [NS-TIs]). Sixty noninfected premature infants and 60 noninfected term infants composed the control group. Receiver operating characteristic (ROC) curves were used to determine the sensitivity and specificity of IL-6, IL-8, and SAA alone and in combination with CRP and PCT. The area under the curve (AUC) was calculated to evaluate the diagnostic value. The clinical characteristics of the subjects were recorded. The expression of CRP, PCT, IL-6, IL-8, and SAA was upregulated in patients with NS compared with control subjects. When the SAA cut-off value was 10.18 mg/L, the greatest AUC for the diagnosis of NS-PIs was for SAA (AUC = 0.833, 95% CI 0.762–0.905, P < 0.001). When the CRP cut-off value was 9.562 mg/L, the smallest AUC for the diagnosis of NS-PIs was for CRP (AUC = 0.776, 95% CI 0.684–0.867, P < 0.001). When the IL-8 cut-off value was 52.03 pg/mL, the greatest AUC for the diagnosis of NS-TIs was for IL-8 (0.821). When the IL-8 cut-off value was 52.03 pg/mL, the greatest AUC for the diagnosis of NS-TIs was for IL-8 (AUC = 0.821, 95% CI 0.745–0.898, P < 0.001). When the CRP cut-off value was 13.18 mg/L, the smallest AUC for the diagnosis of NS-TIs was for CRP (AUC = 0.762, 95% CI 0.667–0.857; P < 0.001). Additionally, according to the AUC value, the best combination was SAA and PCT for NS-PI diagnosis, and the best combination was PCT and IL-6 for NS-TI. In conclusion, compared with PCT and CRP, IL-6, IL-8, and SAA are better diagnostic biomarkers. Moreover, PCT combined with SAA is more suitable for diagnosing NS-PIs, and PCT combined with IL-6 is more suitable for diagnosing NS-TIs.
Post-pandemic insights on COVID-19 and premature ovarian insufficiency
Authors: Han Yaguang , Dai Yang , Wang Kexin , Zhang Xin , Shao Zishen , Zhu Xiaolin
Published: January 2025

The COVID-19 pandemic has raised concerns regarding its potential impact on premature ovarian insufficiency (POI). This overview examines the possible interactions between COVID-19 and POI, while also suggesting preventive measures. The viral infection’s inflammatory response and immune dysregulation may adversely affect ovarian tissues, leading to inflammation and damage. Additionally, alterations in vascular function could impair ovarian blood flow and hormonal imbalances may disrupt normal ovarian function. Long-term health effects, such as “long COVID,” may exacerbate these issues through chronic inflammation and immune dysfunction. Public health measures, such as vaccination and home isolation, may indirectly protect ovarian health by reducing systemic inflammation. Vaccines could mitigate the severity of COVID-19’s impact on ovarian function, while isolation may reduce stress and inflammation. However, further research is needed to validate these mechanisms.

Authors: Oyaert Matthijs , Kouri Timo , Carton Eva , Deprez Sigrid , Lambrecht Stijn , Speeckaert Marijn
Published: January 2025

Objectives

We evaluated the performance of a novel flow cell morphology analyzer AUTION EYE AI-4510 for counting particles in urine.

Methods

Analytical performance was assessed according to the EFLM European Urinalysis Guideline 2023. Trueness was compared by analyzing 1.012 fresh urine samples with the AUTION EYE AI-4510 (ARKRAY, Inc., Kyoto, Japan) against phase-contrast visual microscopy. Poisson statistics were utilized in assessment of imprecision of particle counts both with quality control material and patient specimens.

Results

Relative imprecision against theoretical Poisson imprecision, R(CV), was estimated to be 1.1 for red blood cells (RBC), 1.0 for white blood cells (WBC), 0.9 for squamous epithelial cells (SEC) and 1.1 for bacteria. The agreement with visual microscopy (Cohen’s weighted kappa) was 0.93 for RBC, 0.95 for WBC, 0.90 for SEC, 0.79 for non-squamous epithelial cells (NSEC), 0.67 for combined casts, 0.90 for crystals and 0.88 for bacteria. No clinically significant bias was observed. Limits of quantitation at CV=30 % reached 4 × 106/L for RBC and 5 × 106/L for WBC. Differentiation of urinary crystals was improved as compared to previous data on digital cuvette imaging.

Conclusions

The ARKRAY AUTION EYE AI-4510 provided a desirable imprecision, met the criteria for linearity, LoQ and carry-over, and showed an optimum comparison to visual microscopy for RBC, WBC, SEC and crystals as defined in the EFLM European Urinalysis Guideline 2023. The identification of kidney damage is recommended to be improved by using user-defined review rules. Performance of bacteria counting needs to be confirmed against urine bacterial cultures.
Overview of dengue diagnostic limitations and potential strategies for improvement
Authors: Selvaraj Aruna Devi , Ramaian Santhaseela Anand , Tamilmani Elavarasan
Published: January 2025

Introduction

Dengue is a viral infection caused by any one of the four related dengue virus (DENV) serotypes, 1–4. DENV is a single-stranded RNA virus belonging to the genus Flavivirus. Dengue can cause a range of symptoms, from mild to severe life-threatening illness. Currently, treatment for DENV is limited to supportive care, with better outcomes achieved through early diagnosis. The WHO has suggested that dengue mortality can be reduced to nearly zero by implementing appropriate clinical management strategies, such as early laboratory diagnosis. This calls for diagnostic approaches that combine high sensitivity and specificity, while also being suitable for point-of-care testing (POCT) in remote locations with minimal staff training and low testing costs.

Content

In this paper, we outline the limitations of existing confirmatory dengue diagnostic methods, such as ELISA and RT-PCR, which are time-consuming, expensive, and require skilled personnel. We also highlight alternative strategies to overcome these challenges. Additionally, the paper emphasizes the growing clinical demand for diagnosing severe dengue to reduce the risk of death, which must be addressed by next-generation dengue diagnostic approaches.

We propose the adoption of alternative strategies, such as fluorescence immunoassay (FIA) and chemiluminescence immunoassay (CLIA), which have the potential to overcome the limitations of existing dengue diagnostic methods.

Outlook

Improvements in dengue diagnosis, with a specific focus on identifying severe dengue in POCT setting, can help achieve the goal of zero deaths from dengue.
Neutronic analysis of a lithium-cooled space nuclear reactor based on sliding reflector design
Authors: Wang Yue , Wei Bin , Wang Jincheng , Zhang Wenchao , Sun Jianchuang , Cai Weihua
Published: January 2025

The sliding reflector control system is utilized for core power level regulation through neutron leakage, offering a simpler structure in comparison to the control drum and control rod systems, thus minimizing the mass of the space reactor. This paper presents a conceptual design of a small – scale homogeneous lithium-cooled space fast reactor based on the sliding reflector control system. In this study, accurate modeling of the radial subregion of the reflector block is achieved, and the influence mechanism of the leakage rate on the key parameters of core neutronics is quantitatively analyzed. By pulling down the sliding reflector layer until the core reaches the critical state, the designed core shows a negative reactivity temperature coefficient of −0.3083 pcm/K. Meanwhile, the peak value of the inhomogeneity coefficients for axial and radial neutron flux density distributions are 1.414 and 1.268, respectively, satisfying safety and economic requirements. The analysis indicates that changes in the neutron leakage rate directly impact the reactivity. Building upon these findings, three reflector arrangement schemes summarizing all possible sliding scenarios are proposed: the uplift sliding reflector, the down-sliding reflector, and the intermediate separating sliding reflector. The results of neutron calculations show that the down-sliding reflector has the largest adjustment accuracy, with reaching criticality when the axial leakage length reaches 2.85 cm. The uplift reflector produces the most uniform axial neutron flux density distribution, peaking at 1.341.
Risk analysis and protection in case of intrusion of nuclear facilities
Authors: Wadoud Amir A. , Saleh Alaa A. , Abdel-Rahman Mohamed A.E.
Published: January 2025

Physical protection systems (PPSs) are designed to counter and neutralize any theft or sabotage attempts carried out against a given site. PPS designs are crucial, requiring rigorous analysis and evaluation to ensure their reliability, sustainability and optimal security. This paper assumes a Hypothetical Nuclear Research Center (HNRC) for PPS analysis and evaluation. This work will determine the PPS’s most vulnerable path elements, by demonstrating expected intrusion attack scenarios by taking advantage of the HNRC’s design weaknesses. Also, this work determines the threats resulting from adversary intrusion through the weakness path elements located at the nuclear site. Additionally, this paper develops an analytical methodology for this evaluation and risk assessment, by using the Systematic Analysis of Vulnerability to Intrusion (SAVI) computer program. Through constructing adversary sequence diagrams (ASDs), SAVI can easily identify the HNRC’s most vulnerable paths, pinpointing the areas which require the most attention. Alongside SAVI is the quantitative risk analysis method - the Dai et al. Model – which can calculate the effectiveness and risk of the PPS itself by measuring its degree of uncertainty using effectiveness entropy. To comply with effectiveness and risk standards, this work also introduces security system upgrade processes and determines the optimal security solution for the HNRC.

This study presents a quantitative assessment of cross-linked polyvinyl alcohol (PVA) granules as sensing elements for detecting aliphatic carboxylic acids and their sodium salts in aqueous solutions. Swelling kinetics were measured across solute concentrations ranging from 0.2 N to 1.0 N, with the granule radius varying between 0.31- and 0.43-mm. Results indicated that both carbon chain length and the presence of additional carboxyl groups exert a pronounced effect on the equilibrium swelling degree, thereby highlighting the interplay between hydrophobic interactions and hydrogen-bond formation. To interpret these observations, a heterophase physicomathematical model was employed, yielding three main kinetic coefficients (K1, K2, and K3) that capture solvent flux, polymer network elasticity, and solute transport. The model fits exhibited root-mean-square deviations below 1 %, attesting to its reliability in describing complex swelling - deswelling processes. Additionally, three-dimensional kinetic surfaces were constructed to illustrate how swelling evolves over time and concentration, revealing that initial swelling curves can serve as a rapid indicator of solute concentration. By leveraging the reversible nature of polymer swelling, this method offers a non-invasive, cost-effective approach suitable for monitoring organic acids in diverse fields such as environmental analysis, pharmaceutical processes, and chemical engineering.

Published: January 2025

To address the critical role of atmospheric temperature in climate change and disaster monitoring, enhancing measurement accuracy to 0.1 °C is essential. Current instruments are susceptible to radiation interference, resulting in errors of approximately 1 °C. This study introduces a novel temperature sensor that improves accuracy by combining natural ventilation with forced ventilation. Silver-coated aluminum plates (95 % reflectivity) and white-coated deflectors (87 % reflectivity) minimize solar radiation errors. A neural network algorithm, along with CFD simulations, further corrects radiation errors under varying weather conditions. Field tests based on the 076B ventilation device demonstrate that this new sensor reduces the average radiation error to 0.02 °C, achieving a RMSE of 0.034 °C and a MAE of 0.028 °C. The correlation coefficient (r) with the reference temperature reached 0.999, demonstrating the sensor’s high precision and providing an effective solution for reducing temperature measurement errors to below 0.1 °C.

Entre los grandes misterios de la ciencia, el origen de la vida es uno de los más difíciles de descifrar. Para rastrear la historia de la vida en la Tierra, se recurre al estudio de las rocas buscando microestructuras que puedan ser restos de la vida primitiva. El precámbrico fue un periodo de grandes modificaciones geológicas, comenzando a surgir las formas de vida primarias. Debido a los avances, se ha confirmado que en las condiciones de la Tierra primitiva era común encontrar agua con pH alcalino, favoreciendo la autoorganización de pequeñas moléculas minerales formadas de silico-carbonatos de metales alcalinotérreos. Entre otras cosas, estas eran capaces de formar estructuras inertes que tienen una forma, textura y una simetría similar a las de los seres vivos, las cuales han sido denominados biomorfos. El objetivo del proyecto fue evaluar la síntesis de biomorfos sobre un mineral en diferentes condiciones atmosféricas.

Este estudio examina los determinantes del aumento de los precios de la vivienda en México, destacando el papel de la migración interna. Utilizando datos de la Sociedad Hipotecaria Federal y el Consejo Nacional de Población para el período 2005-2021, analizamos el impacto de factores demográficos y económicos en la demanda y los precios de la vivienda. Nuestros hallazgos indican que la migración interna impulsa significativamente la demanda de vivienda. Esta migración redistribuye la población hacia áreas urbanas, aumentando la presión sobre la demanda de vivienda y elevando los precios. En particular, estimamos que la elasticidad promedio del precio a cambios en la migración interna ronda el valor de 0.02. Un análisis a nivel estatal muestra que este valor es debido a la heterogeneidad del efecto de la migración interna sobre el precio. En particular, mostramos que los estados con mayor dinámica migratoria (reciben población) el efecto sobre el nivel de precios es 10 veces mayor que el promedio nacional estimado. Este resultado sugiere que el efecto de la migración interna es relevante en la fijación del precio de vivienda en las entidades federativa con mayor flujo de inmigrantes.

Literary competitions have always been an important element of literature and culture, a testimony to their evolution and tools supporting the development of the nation or consolidating the community, they increased the intellectual level of residents, and were also an instrument of literary life. Women’s participation in these competitions was limited due to strongly rooted patriarchal social norms, the subordinate role of women, and rigid conventions that eliminated them from many spheres of public life, including literature and artistic activity. Since the beginning of the LIMES competition, one can also notice begin ning poets and writers who tried their hand at art. The article presents this poetry and prose, its character and meaning.
Puścizna. Kaduk. Odumarszczyzna. Kilka uwag o terminologii dawnego prawa polskiego
Authors:   Uniwersytet Łódzki, Głuszak Marcin
Published: January 2025

Terminological studies, including research on the meaning of words encountered in sources, are of particular value to legal historians. Despite this, in modern academic textbooks on the history of law, relatively little space is dedicated to the old Polish legal terminology, including the nomenclature regarding heirless inheritances. The authors of books for students, when describing the rules of inheritance applicable in the former Polish-Lithuanian Commonwealth, reduce their arguments to the necessary minimum, limited by the requirements of the textbook. Using the terms “kaduk” and “puścizna” for this purpose, is interchangeable, without indicating any differences in the meaning of both words. Therefore, they do not present the origins and evolution of the meaning that these words have undergone over the centuries. Moreover, the terms “odumarszczyzna” or “odumarlizna” that appear in the sources, with a few exceptions, are not recorded or explained in the latest textbooks. This raises serious concerns about the gradual limitation of the content transmitted in the field of legal history Therefore, it seems reasonable to examine whether the terms mentioned above are synonyms and whether their interchangeable use is justified. For this purpose, it is worth recalling the meaning of the words “kaduk”, “puścizna” and “odumarszczyzna”, referring to old Polish dictionaries, Latin-Polish dictionaries, selected source texts and views expressed by historians of old-Polish law: Maciejowski, Burzyński, Dutkiewicz, Bandtkie or Dąbkowski, who, using various sources, including those no longer available today, thoroughly researched the subject and terminology of inheritance law.

In the Majesty of the Law? Jewish Residents of Warsaw in the Face of German Occupation Ordinances and Activities of Sondergericht Warschau – Part I
Authors:   Uniwersytet Mikołaja Kopernika w Toruniu, Bartnicka Alicja , Graczyk Konrad ,   Uniwersytet Śląski w Katowicach
Published: January 2025

The article focuses on the attitude of the Warsaw’s Jewish population toward selected, most significant anti-Jewish laws passed in the General Government during World War II. Due to the breadth of the analyzed material, the text is divided into two main parts. The first part presents the Ordinance on forced labor for the Jewish people of October 26, 1939, and the Ordinance prohibiting ritual slaughter of October 26, 1939. The objective of the different ordinances was to regulate the lives of Jews under occupation. The first ordinance led to the exploitation of, and the second led to discrimination against, Jews. The authors discuss their content, reception among Jews, and the practice of application by the German Special Court in Warsaw (Sondergericht Warschau). Indeed, the German Special Court in Warsaw considered cases involving violations of individual ordinances in the Warsaw District. To prepare the author analyzed literature on the subject, including memoirs, press articles, as well as archival sources of judicial provenance. Historical and formal-dogmatic methods were used during the research. The article looks at not only the reception of the anti-Jewish laws themselves by the population they targeted. Not only the trials and the enforcement of the imposed sentences were of particular interest to the authors, but also the strategies pursued by Warsaw’s Jews to better cope with the new legislation that came into force under the German occupation. The research made it possible to show German legislative policy in the context of actions aimed at the exploitation, discrimination, stigmatization, and isolation of Jews.

This research aims to analyze the influence of a metacognitive-based learning model on agile innovation and critical thinking abilities of students in science learning at elementary school level. The study population consists of fourth-grade students in elementary schools. The sample was selected using cluster random sampling with an intact group type in Bali. Participants in this research study are Grade 5 students in elementary schools in Bali Province, Indonesia. Samples were taken using a cluster random sampling technique with intact group type. Based on the sampling results, the experimental class comprised 32 students, who received pedagogical intervention in the form of metacognitive-based learning implementation, while the control class with 31 students was exposed to conventional learning models. A survey questionnaire was employed as data collection instrument. Data analysis included descriptive and inferential analysis. Based on the analysis of agile innovation data, an F-value of 23.994 was obtained with a significance value of 0.000 (<0.05). From these results, it can be concluded that there is a significant difference in agile innovation between students who experienced metacognitive-based learning and those who did not. The group of students who received metacognitive-based learning showed a higher level of agile innovation with an average score compared to the group of students who did not experience metacognitive-based learning. Additionally, data on critical reasoning abilities showed an F-value of 20.915 with a significance value of 0.000 (<0.05). In conclusion, there is a significant difference in critical reasoning abilities between students who received metacognitive-based learning and those who did not.

[Introduction]: The lack of feasible circular economy models for recycling single-use plastics poses a significant challenge to sustainable waste management. Single-use plastics, particularly flexible types, contribute to environmental pollution and require effective recycling strategies. [Objective]: This study aimed to analyze global recycling models for single-use plastics under key parameters: type of pollutant, impacts on sustainability, value generation, stakeholders involved, and level of technology. [Methodology]: A global review of 21 circular economy models focused on single-use flexible plastics was conducted, evaluating their feasibility and effectiveness. Six models were identified as the most relevant based on the selected criteria. [Results]: The findings indicate that improving eco-efficiency requires the integration of physical and chemical recycling processes to achieve cost reductions. Additionally, maintaining a constant flow of recyclable materials is essential, emphasizing the critical role of material collection and classification cooperatives. In Colombia, the collection and classification of plastic materials emerged as a pivotal element for the long-term sustainability of recycling models. [Conclusions]: The study highlights the necessity of combining technological and logistical efforts to enhance recycling processes. Strengthening material recovery systems and cooperative efforts is crucial for advancing circular economy goals in the context of single-use plastics.

One of the trigger mechanisms for the development of neurodegeneration is glutamate excitotoxicity. The ATP-dependent enzyme glutamine synthetase, localized in astrocytes, regulates glutamate homeostasis by catalyzing the synthesis of glutamine from glutamate and ammonia. The purpose of the study was to identify age- and sex-specific changes in glutamine synthetase activity in a streptozotocin-induced model of Alzheimer-type neurodegeneration. The experiments were carried out on 60 old (at the age of 24 months) Wistar rats of both sexes, divided into groups: 1) control (intact) rats; 2) sham-operated rats; 3) rats with intraventricular injection of streptozotocin. using intraventricular injection of streptozotocin. In males, enzymatic activity decreased in the cortex, cerebellum, hippocampus, and hypothalamus by 40%, 33%, 36%, and 26%, respectively, compared with control rats. In females, the decrease was more pronounced, which amounted to 47% in the cortex, 39% in the cerebellum, 43% in the hippocampus, and 32% in the hypothalamus. Thus, the decrease in glutamine synthetase activity is due to age-dependent impairment of glutamate neurotransmission, reduced compensatory capabilities of neurons and altered hormonal status.

The aim of the study was to investigate an oxidative processes intensity and structural organisation of hard and soft periodontal tissues in rats under conditions of high-fructose diet against the background of iodine deficiency (research group) and standard diet and drinking regime (intact animals). It was found that carbohydrate metabolism was impaired in rats of the research group (glucose content increased by 63.3%, insulin – by 48.2% in blood serum, glycated haemoglobin of whole blood – by 2.1 time, HOMAIR index – by 2.1 times compared to the data in intact rats) and thyroid status (free triiodothyronine and thyroxine content in blood serum decreased by 46.8 and 42.7%, respectively, compared to the control). Under such conditions, the intensity of lipid and protein peroxidation processes in periodontal tissues increases. In particular, the accumulation of diene conjugates and products that react to thiobarbituric acid in the mucous membrane of the alveolar process (by 19.0 and 7.1 times), in the teeth pulp (by 2.2 and 6.3 times) compared to the values in intact animals was found. The activation of peroxidative destruction of proteins is confirmed by an increase in the content of all fractions of their oxidative modification in the studied tissues by 2.8-8.4 times compared to the control values. The results of the histological examination of the alveolar process indicate thinning of the periosteum, disruption of the structural organisation of osteon, reduction in the thickness of bone trabeculae (by 21.8%), optical density of the osteogenic matrix (by 8.9%), area of intertrabecular connective tissue (by 61.0%). Mucosal edema of connective tissue, accumulation of glycosaminoglycans, hypertrophy of all epithelial layers (basal, prickle, keratinized layers – by 25.5-55.9%, granular layer – by 2.3 times), changes of the microcirculatory net were observed in the mucous membrane of the alveolar process. Thus, the combination of high-fructose and iodine-deficient diets causes the development of oxidative stress and destructive changes of the dentoalveolar complex of research animals, which characterises an increase of the risks of dental pathology development.

Published: January 2025

Стаття присвячена дослідженню питання формування культурного виміру образу світу в аспекті взаємозв’язку філософії та мистецтва. У ній висвітлено специфіку філософського знання та мистецтва, як галузі людської культури, спрямованої на естетичне відчуття світу. Охарактеризовано подібні та відмінні аспекти між філософією та мистецтвом. З’ясовано зв'язок між мистецтвом та філософією. Охарактеризовано вплив поєднання філософії та мистецтва на розвиток культури.
Актуальність дослідження обумовлена потребою у міждисциплінарному дослідженні проблем духовної діяльності людини, де філософія та мистецтво є тими особливими галузями знань, що вагомо впливають на розвиток нашого суспільства. Філософія як теоретична основа світогляду оперує методологією, що визначає напрям наукових досліджень інших наук, зокрема, мистецтвознавства. Тобто, два вида духовної діяльності людини – філософія та мистецтво – демонструють складну й багатопланову спорідненість, хоча й відсутня тотожність у сутності та проявах функціонування. Водночас саме співвідношення філософії та мистецтва є показником рівня розвитку культури у різних аспектах.
Метою дослідження є розкриття формування культурного виміру образу світу в аспекті взаємозв’язку філософії та мистецтва.
Результати. Згідно з проведеним дослідженням було з’ясовано, що абстрактно-теоретичні узагальнення філософії та мова образів про неймовірне мистецтва є тими сферами, які характеризують трансцендентне застосування раціональності та чуттєвості в контексті соціального. Все це перетворює дані сфери у джерело розуміння людини як колективної істоти. Водночас визначено, що вплив філософії та мистецтва на культуру опосередкований тим, що дані науки дозволяють людині зрозуміти красу навколишнього світу та духовного наповнення людини.
Висновки. Отримані результати дослідження свідчать про значущість впливу філософії та мистецтва на людинотворчий статус культуру.
Колаборантський характер радянських парамілітарних формувань на заході Україні на завершальному етапі другої світової війни та в перші повоєнні роки в оцінці сучасної української історіографії
Authors: Щеглов Андрій

Актуальність. Широкомасштабна агресія РФ проти України із тимчасовою окупацією частини нашої держави та репресії проти місцевого населення вимагають переглянути напрацювання вітчизняної історіографії відновлення радянської влади на Заході Україні на завершальному етапі Другої світової війни крізь призму концепту колабораціонізму.
Мета дослідження – дослідити колаборантські прояви радянських парамілітарних формувань на західноукраїнських землях на завершальному етапі Другої світової війни та в перші повоєнні роки в інтересах сталінського тоталітарного режиму через постановку та розкриття нової міждисциплінарної проблематики.
Результати. Вказані формування та їхніх учасників не можна віднести до усталеного розуміння колабораціонізму й колаборантів відповідного історичного періоду. Причини, характер, сутність та результати вступу та боротьби частини мешканців західноукраїнського краю на боці сталінського тоталітарного режиму проти не тільки учасників ОУН-УПА, але цивільного, переважно українського, сільського населення, дозволяють виокремлювати у їхній діяльності ознаки колаборантської діяльності, що використовувалися репресивно-каральними органами НКВС, як через провокацію міжнаціонального польсько-українського конфлікту, так і ескалацію протистояння на соціально-побутовому та міжособистісному ґрунті. Пропонується оригінальна міждисциплінарна інтерпретація причин, характеру та наслідків співучасті частини місцевого населення у винищувальних батальйонах як допоміжних структурах радянських репресивно-каральних органів в боротьбі з українським національно-визвольним рухом через критичну інтерпретацію здобутків сучасної вітчизняної історіографії проблематики колабораціонізму.
Висновки. Комплексно охарактеризовано попередні результати вивчення сучасною вітчизняною історіографією радянських парамілітарних формувань на Заході Україні на завершальному етапі Другої світової війни та в перші повоєнні роки.
