Authors: Jančárková Natalia , Krkavcová M. , Janashia M. , Freitag P. , Dušková J. , Cibula D.
Published: November 2024

The aim of the study was to estimate genetic alterations detected in ovarian cancer cells in correlation with other available parameters of histopathological and clinical character and to find important relations with impacts on the cancer prognosis. Additionally, we wanted to compare methods for evaluating genetic changes. Sixty patients with ovarian cancer were included in the study. The histological type and grade were defined, MIB-1 and p53 were estimated using an immunohistochemical method. For genetic testing, both conventional and molecular methods were applied – direct culture and G-banding technique, FISH method with whole chromosome painting probes, and CGH method. The results were submitted to statistical evaluation, using analysis of variances and χ2 test, with Bonnferroni correlations of the significance level. Numerical and structural aberrations have been detected in more than 63 % examined ovarian cancer cases. Patients with extensive chromosomal rearrangements were significantly younger. Specific genetic alterations, including some rare findings such as deletion 22q in 36 % of all ovarian cancer samples, have been found, together with associations between particular prognostic factors.

Published: November 2024

Salinity, a critical environmental stressor, imposes constraints on field crops' anatomical structure, growth, and physiology. This study has uniquely evaluated the effect of 0 (control), 100, and 200 mM NaCl on phenolic acids (PAs), total anthocyanin content (TAC), chlorophyll, and antioxidant activity in three radish varieties and contributes novel insights to the scientific co community. The salt concentration significantly influenced shoot length (SL), root length (RL), and fresh weight (FW) in radish sprouts. The varying salt concentrations did not affect chlorophyll a, but chlorophyll b and total chlorophyll content (TCC) increased the red and super red varieties. The total phenolic content (TPC) and total flavonoid content (TFC) registered a slight increase in some varieties under 100 mM salt concentration, with the highest accumulation of these secondary metabolites found in the super red variety. Five individual PAs were identified using high-performance liquid chromatography (HPLC) analysis, with salt treatment significantly affecting ferulic acid and trans-cinnamic acid concentrations. The lowest level of anthocyanin was found in all green varieties. Salinity stress of 100 and 200 mM affected the TAC in the red and super red varieties compared to the control. Furthermore, among the three varieties treated with NaCl, the super red IC50 values displayed the highest 2,2,1-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-Azino-bis-3-ethylbenzothiazoline-6-sulfonic Acid (ABTS) free radical scavenging activity compared to the other treatments. These results suggest that a 100 mM NaCl concentration can be used as an inducer to improve the accumulation of phytochemicals in the radish seedlings 12 days after sowing (DAS).
Історія дослідження виробів з виїмчастими емалями київської культури
Authors: Abrazumova Olena M.
Published: November 2024

The article analyses the history of research and study of jewellery production by the people of the Middle and Upper Dnieper region in the late Roman period. One of the most recognizable products of the area and time in question are ornaments with carved enamels. The first attempts to understand them started over a century ago. During the first half of the 20th century, the ethnocultural affiliation of the circle of carved enamel decorations was debatable. With the selection of Kyiv culture (the indicated original products of applied art being among the signs thereof), another dimension is added to the study of enamelled jewellery. Modern archaeologists have not tired of the chronology, cataloguing and classification, technological, the artistic and stylistic aspects of the production of jewellery and metal parts of clothing of the Kyiv culture, or attempts at understanding of the phenomenon of recessed enamels. The rapid growth of the finds of jewellery and elements of clothing with carved enamels has led to another perception of their distribution and habitation, and the origins of the style of the jewellery of Kyiv masters.

Philosophizing the Indefensible: Reply to Critics
Authors: Nili Shmuel
Published: November 2024

This essay responds to the central critiques of Philosophizing the Indefensible advanced by Nuti, Kapelner, and Garcia-Gibson. Nuti and Kapelner pose general challenges to the strategic method driving the book. Garcia-Gibson focuses on this method’s application to green energy policies. I explain why I believe that both the general account of strategic theorizing presented in the book and its specific green-energy arguments withstand the critics’ scrutiny.

Published: November 2024

This study was conducted to evaluate the response of the double-bottom structure on a ship when a fire phenomenon involves temperature elevation and depreciation. Fire accidents on ships can be very detrimental, especially since ships are the main transportation for export and import activities. Therefore, this research is needed to reduce the risk of fire accidents on ships, especially on double-bottom structures. This study used the finite element modeling method in ABAQUS software. The research results found that the Von Mises stress contour, strain, and displacement values were influenced by the type of material, temperature, and plate thickness. Based on the results evaluated using the multi-attribute decision-making method, model 32 is the best model, while model 95 is the worst. Concurrently, from sensitivity analysis, it was found that temperature plays a significant role in the results of Von Mises Stress, Strain, and Displacement. The results indicated that the main factor influencing the Von Mises stress, strain, and displacement is the loading in the form of temperature, followed by material properties and plate thickness.
High school students’ perceived performance and relevance of chemistry learning competencies to sustainable development, action competence, and critical thinking disposition
Authors: Ramirez Hazel Joyce , Paderna Edwehna Elinore
Published: November 2024

Chemistry is deeply interconnected with various aspects of sustainability. However, enabling students to analyze these interconnections requires adequate support in learning. Moreover, few studies have explored the connection between students’ perceptions of chemistry learning competencies and their sustainability competencies that could be the basis for improving pedagogical practices. Therefore, this research investigated Filipino Grade 12 students’ perceived performance and relevance of chemistry learning competencies to sustainable development. Moreover, this study explored the students’ sustainability competencies, specifically action competence and critical thinking disposition. The Performance-Relevance Grid Analysis categorized the learning competencies based on the extent of perceived performance and relevance. Furthermore, the analysis also showed a correlation between students’ perceived performance and relevance (p = 0.015). Additionally, critical thinking disposition was found to be correlated with students’ perceived performance (p = 0.002) and relevance of chemistry learning competencies (p = 0.036) as well as with action competence (p < 0.001). Research findings provide crucial insights for future research and practice that could drive the integration of sustainability in chemistry education. This integration not only enhances the relevance of chemistry, but also encourages students to see the broader implications of their studies in the context of sustainable practices and societal impact.
Efficient scheme for a category of variable-order optimal control problems based on the sixth-kind Chebyshev polynomials
Authors: Sadri Khadijeh , Hosseini Kamyar , Salahshour Soheil , Baleanu Dumitru , Ahmadian Ali , Park Choonkil
Published: November 2024

The main goal of the present study is to introduce an operational collocation scheme based on sixth-kind Chebyshev polynomials (SCPs) to solve a category of optimal control problems involving a variable-order dynamical system (VODS). To achieve this goal, the collocation method based on SCPs, the pseudo-operational matrix for the fractional integral operator, and the dual operational matrix are adopted. More precisely, an algebraic equation is obtained instead of the objective function and a system of algebraic equation is derived instead of the VODS. The constrained equations obtained from joining the objective function to the VODS are ultimately optimized using the method of the Lagrange multipliers. Detailed convergence analysis of the suggested method is given as well. Four illustrative examples along with several tables and figures are formally provided to support the efficiency and preciseness of the numerical scheme.
The Collaboration of Teaching at The Right Level Approach with Problem-Based Learning Model
Authors: Mustafa Sriyanti , Riana Rika , Baharullah Baharullah , Maming Khadijah
Published: November 2024

This study aims to explore the effectiveness of collaboration between the Teaching at the Right Level (TaRL) approach and the problem-based learning (PBL) model in improving student learning outcomes at junior high school and senior high school levels. TaRL is a method that emphasizes learning tailored to students’ individual ability levels, while PBL focuses on PBL that encourages students to develop critical thinking and problem-solving skills independently. In this study, 73 students participated in two cycles of learning practices integrating the two approaches. The results of the initial diagnostic test were used to group students based on their ability levels, which were then followed by the implementation of learning using problem-based scenarios according to their groups. Quantitative data were obtained through learning outcome tests and analyzed using descriptive statistics and ANOVA. The mean value of students’ final test results reached 79.73, indicating a significant increase in understanding after the implementation of this method. However, the ANOVA results showed that there was no significant difference between the tested groups, with a p-value of 0.662 and an F-statistic of 0.414. In addition, in-depth interviews were conducted to understand students’ perceptions of the applied learning method. The results of the interviews revealed that students felt more engaged and motivated in the learning process, especially since the materials were tailored to their abilities and they were given the opportunity to solve problems relevant to real life. However, variations in learning outcomes were still evident, indicating the need for further adjustments in the approach to reduce performance disparities between students. This study concludes that the collaboration of TaRL and PBL can be an effective strategy for improving learning outcomes. However, adaptation and continuous monitoring are needed to ensure that all students can benefit the most from this approach.
Endothelial cell phenotype is linked to endothelial dysfunction in individuals with a family history of type 2 diabetes
Authors: Alvarado-Vásquez Noé , Sommer Bettina , González-Trujano María Eva
Published: November 2024

Objectives

The patient’s family history of type 2 diabetes (FH-DM2) has been negatively associated with the functionality of endothelial cells (ECs). Our objectives in this work were to use human umbilical vein endothelial cells (HUVECs) as a model, to substantiate whether FH-DM2 influences endothelial phenotype and impairs NO and ROS synthesis, cell metabolism, and mitochondrial activity of ECs from individuals with FH-DM2.

Methods

In this study were evaluated the synthesis of reactive oxygen species (ROS) and nitric oxide (NO), mitochondrial membrane potential (MMP), mRNA of eNOS, glucose consumption, and lactate synthesis in HUVECs from newborns with FH-DM2. Furthermore, we also evaluated EC complexity and cell size through flow cytometry.

Results

Our results showed significant differences in HUVECs with FH-DM2, regarding their complexity and cell size, in the synthesis of ROS (p<0.01), and NO (p<0.05); they also reflected diminished glucose consumption and slight changes in the lactate levels.

Conclusion

In conclusion, our results showed that HUVECs from children with FH-DM2 have a reduced capability of synthesizing ROS and NO, which might be linked to the metabolism of endothelial cells. These results are relevant since early endothelial dysfunction has been reported in individuals with FH-DM2, and could be used to establish preventive measures to reduce the risk of developing atherosclerosis or cardiovascular diseases in healthy individuals, but with this family background.

Authors: Zhao Xuan , Shen Ya
Published: November 2024

Objectives

To evaluate the diagnostic value of ultrasound spectra of the middle cerebral artery (MCA) and umbilical artery (UA) blood flow in predicting adverse pregnancy outcomes.

Methods

Data from 202 late singleton pregnancies (32–34 weeks gestation) were analyzed. Group A included 155 normal pregnancies, while Group B comprised 47 high-risk pregnancies. Color Doppler ultrasonography was used to measure and compare pulsatility index (PI), resistance index (RI), and end-systolic peak/end-diastolic peak (S/D) ratios of fetal MCA and UA between the groups.

Results

UA-related parameters (PI, RI, and S/D) were significantly higher in Group B compared to Group A, whereas MCA-related parameters (PI, RI, and S/D) were significantly lower in Group B than in Group A. In pregnancies with adverse outcomes, fetal UtA and UA-related parameters were elevated, while MCA parameters were decreased compared to those with favorable outcomes.

Conclusions

Ultrasound spectra of MCA and UA blood flow provide valuable clinical information for assessing fetal intrauterine growth and predicting adverse pregnancy outcomes.

Biodegradability of corn starch films containing nanocellulose fiber and thymol
Authors: Nordin Norhazirah , Fisal Muhamad Farhan , Othman Siti Hajar , Tawakkal Intan Syafinaz Mohamed Amin , Basha Roseliza Kadir
Published: November 2024

The biodegradability of corn starch (CS), CS/nanocellulose fiber (NCF), and CS/NCF/thymol (Thy) films produced via a solvent casting method was investigated by soil burial test (SBT) in two types of soils (compost and planting). The films were evaluated in regard to weight loss, visual appearance, morphological properties, and structural properties. Based on SBT, CS/NCF films exhibited the least weight loss and changes in visual appearance, morphology, and structural properties. The inclusion of Thy into CS/NCF films increased substantially the degree of degradation of films in both soils. The microscopy images of films after SBT show that all of the films had voids, holes, and rough surfaces especially films containing Thy, indicating that the films degraded. Fourier-transform infrared spectroscopy results revealed shifting of peaks and changes in peak intensity of some functional groups of films, confirming the degradation phenomenon. Compost soil has more organic material, active microbes, nutrients, and humidity than planting soil, thus resulting in films with greater weight loss and changes in visual appearance, morphology, and structural properties. It can be concluded that the films have a high potential for applications and can help to lower the amount of usage of non-degradable materials.

Published: November 2024

Soliton solutions play a crucial role in modeling stable phenomena across optical communications, fluid dynamics, and plasma physics, owing to their stability and persistence in solving nonlinear equations. This study centers on the extended Sakovich equation, emphasizing the importance of soliton solutions in predicting and controlling localized wave behaviors, which advances nonlinear dynamics and its various applications due to its integrable properties and flexible soliton characteristics. This equation is applicable across diverse fields such as fluid dynamics, nonlinear optics, and plasma physics, where it effectively models nonlinear wave phenomena, including solitons and shock waves. Additionally, it provides crucial insights into wave propagation in biological systems and acoustics, making it a valuable tool for analyzing complex wave dynamics. Additionally, we investigate bifurcation and modulation instability within this equation, employing the improved Sardar subequation method and the

method to derive solitary wave solutions. These methods yield a diverse range of waveforms – hyperbolic, trigonometric, and rational functions – validated rigorously using Mathematica software for accuracy. Graphical representations vividly display various soliton patterns, such as singular, multi-singular, periodic singular, kink, anti-kink, bell-shaped, Kuznetsov–Ma Breather, and parabolic-shaped, highlighting their effectiveness in revealing innovative solutions. Furthermore, a comparative analysis verified the novelty of our derived soliton solutions. This research significantly contributes to advancing soliton solutions for the Sakovich equation, promising diverse applications across scientific disciplines.

Authors: Otto J.L. , Sönmez M.I. , Brink M. , Donnerbauer K. , Lingnau L.A. , Reisch-Lang L. , Wojarski L. , Walther F.
Published: November 2024

The paper will explain the formation and effects of brittle precipitates in form of borides and silicides during high-temperature vacuum diffusion brazing on the example of a nickel-based filler metal from the NiCrSiB system. This filler metal foil was used to braze butt joints of the metastable austenite AISI 304L. Energy and wavelength dispersive X-ray spectroscopy was applied to identify the precipitates. Using a focused ion beam in scanning electron microscopy, the brazed joint was removed layer by layer over a large area to gain insights into the 3D structure of the precipitates. Subsequently, a methodology will be presented on how to reconstruct a 3D model from the image data using deep learning-based image segmentation. The final model unravels the complex morphology of these precipitates and thus contributes to a better understanding of the solidification and precipitation mechanisms in diffusion brazing.

Published: November 2024

The metallographic revelation of the microstructure of very thin wires and foils is a challenging task. How can a cross-section and a longitudinal section be prepared from a 36 μm thin wire? Or how can a flat section of a weld on 125 μm thin Nitinol sheets be successfully prepared? The preparation is to always allow for representing the crystal orientation by EBSD. Can this be achieved relying on the classical preparation of sections or do newer methods have to be used? This article presents the possibilities of a classical preparation and ion beam polishing.
Nachhaltige Finanzierung der gesetzlichen Rentenversicherung durch inter- und intragenerative Umverteilung – ein Reformvorschlag als Generationenkompromiss
Authors: Seuffert Stefan , Toussaint Philipp
Published: November 2024

Der demografische Wandel löst in der gesetzlichen Rentenversicherung einen Generationenkonflikt aus, der sich zwischen einem ausreichenden Leistungsniveau und tragbaren Beitragssätzen zeigt. Die aktuelle deutsche Rentenpolitik fokussiert sich hauptsächlich auf die Leistungsseite und bewirkt eine ausschließlich intergenerative Aufteilung der demografischen Belastung, die zunehmend zu Ungunsten junger und künftiger Generationen ausgestaltet ist. Stefan Seuffert und Philipp Toussaint untersuchen Reformoptionen zur Lastenverteilung auf inter- und intragenerativer Ebene und unterbreiten einen Reformvorschlag, der in den Zielkonflikten zwischen Beitrags- und Leistungsstabilität sowie zwischen Äquivalenzprinzip und Grundsicherungswirkung Kompromisslösungen erlaubt. Ein nachhaltigkeitsneutraler Sockelschutz bewirkt eine intragenerative Umverteilung zum effektiven Schutz vor Altersarmut ohne Veränderung der intergenerativen Lastenteilung. Die intragenerative Umverteilung eines solchen Sockelschutzes von 28 Entgeltpunkten ist zur Stützung der Rentengrundsicherungsquote mehr als fünfmal so effektiv wie die intergenerative Umverteilung von 432 Milliarden Euro durch eine Rentenniveauhalteline von 48 Prozent.

Authors: Ostrowska-Ligęza Ewa , Cichocki Wojciech , Baranowska Hanna Maria , Kowalczewski Przemysław Łukasz
Published: November 2024

The aim of this study was to develop yeast-based microcapsules (YBMCs) containing vegetable oil blends with n3/n6 fatty acids in a ratio of 5:1. The oil blends, as well as YBMCs with these oils, were analyzed in nitrogen and oxygen. The shape and course of the TG and DTG curves were observed for yeast cells with all types of oil blends. No differences were observed in shape because of the microencapsulation curves with all oil blends between YMBCs prepared using native and autolyzed yeast. The results show that the yeast cells could be used as efficient microcarriers for the encapsulation of cold-pressed oils in order to provide thermal stable ingredients for the food industry.
Hayek e Darwin em oposição a Nietzsche da crítica à ideia de evolução social
Authors: Perboni Viviane
Published: November 2024

O presente artigo tem a intenção de explicitar através das obras do filósofo austríaco Friedrich Hayek  a sua defesa em relação  a sua  ideia de  ordem espontânea (aqui explicitadas no sentido de evolução humana) onde o autor busca embasamento a sua defesa nas teorias darwinistas,  pensamentos esses (Hayek e Darwin)  que  são avessos à leitura niilista da história, da moral, da sociedade  e da política,  e que serão abordadas através da  análise do parágrafo: "Anti-Darwin" da obra Crepúsculo dos Ídolos, cap. IX, Incursões de um extemporâneo. Sob um enfoque de diferentes  concepções de analisar a evolução do homem em sociedade aqui demostradas através de  (Hayek/Darwin versus Nietzsche) o presente trabalho vem a propor uma  "análise sobre a evolução das sociedades"  através de uma perspectiva liberal e “jus filosófica"  procurando mostrar que é possível uma outra leitura da evolução da sociedade e da política, diferente da de Nietzsche.
MISTICISMO E RELIGIÃO EM HENRI BERGSON
Authors: Brito da Rocha Dilson
Published: November 2024

Neste estudo temos o objetivo de examinar o modus operandi com o qual Henri Bergson arquiteta sua filosofia da religião, centrando-nos em sua obra intitulada As duas fontes da moral e da religião. Ele versa sobre a religiosidade pari passu com a noção acerca da evolução da natureza, que constitui na expressão da criação. No que toca às duas fontes, assere sobre a religião desde o ponto de vista da institucionalidade, que representa o nicho social, como também a partir do estofo metafísico. Isso equivale aos dois sentidos da palavra religião. Para Bergson, as duas fontes, por meio da intuição, atingem a duração absoluta do universo, e fazem parte de um processo movente, em direção ao amor divino. De qualquer maneira, a religião é pensada pelo filósofo francês como consequência natural do atravessamento do élan no percurso da vida humana, capaz de, pela figura do místico, acessar o divino, se valendo da via do amor. Logo, o misticismo é designado como forma dinâmica da religião, sendo o místico, por conseguinte, não alguém que simplesmente contempla, mas que age e extrapola os muros eclesiásticos.
Life-Affirming Horror and the Films of Jane Schoenbrun
Authors: Benson-Allott Caetlin
Published: November 2024

Filmmaker Jane Schoenbrun’s trilogy of films are not horror movies but movies about horror media that collectively proclaim horror’s value for its trans, queer, and otherwise vulnerable fans. A Self-Induced Hallucination (2018), We’re All Going to the World’s Fair (2021), and I Saw the TV Glow (2024) demonstrate three fundamental truths about horror media, horror fandom, and their utility: (1) Horror creates community; (2) Horror provides a means of processing reality; and (3) Horror helps its fans manage the difficulty of self-discovery. Schoenbrun’s films extol horror’s life-affirming functions, which are often overlooked in critiques of its morbidity and pathologizations of its fans.

Authors: Castro Méndez Didier Alberto
Published: November 2024

This research was focused on exploring the relationship between self-esteem, anxiety and mathematical motivation in precalculus students of the Metropolitan Campus of the Latin American University of Science and Technology (ULACIT in Spanish), during the first quarter of 2024. Possible differences in terms of gender and area of study were analyzed for each of the variables. The methodological approach adopted was of a quantitative descriptive-correlational nature. The sample consisted of 374 pre-calculus students. To carry out the analysis of the hypotheses proposed, Student’s t and Pearson’s correlation statistical techniques were used. The findings revealed that males showed higher levels of anxiety and lower motivation towards mathematics than females. No significant differences in anxiety, mathematical motivation, and self-esteem were identified according to the area of study. A correlation was observed between the variables: as mathematics anxiety decreased, self-esteem and motivation towards the subject increased. In addition, an increment in mathematical motivation was related to an increase in self-esteem. The study showed that 22.46% of the students presented high levels of mathematical anxiety, while more than 55% showed high levels of self-esteem and mathematical motivation.

Application of regional culture in wooden furniture styling design based on extension semantics and shape grammar: Taking Su-Style stool as an example
Authors: Xue Guanlan , Chen Jinglian
Published: November 2024

In view of the current problems of insufficient furniture innovation and uniform styling, this article introduces regional culture to conduct innovative strategic research on existing wooden furniture styling, trying to explore the connection between furniture and culture. Based on the methods of extension semantics and shape grammar, the traditional Chinese furniture Su-style stool is used as an example to demonstrate its feasibility. This work mainly applies extension semantics to illustrate regional culture and combines shape grammar to integrate the cultural elements and furniture shapes, thereby creating new wooden furniture forms with regional cultural characteristics. The article not only draws a genealogy chart of Suzhou’s regional culture, but it also extracts a number of semantics and graphics to describe Suzhou cultural characteristics. It expands the graphics into relevant elements as a replacement library to replace some of the DNA genes of the stool by shape grammar, allowing the new stool to carry the cultural memories of Suzhou. Finally, the work generated three design practices, which were evaluated by excellence evaluation method. In conclusion, the article demonstrated that the combination of extension semantics and shape grammar can effectively guide the design of wooden furniture with regional cultural characteristics.

Published: November 2024

Este manuscrito apresenta um relato da aplicação da Metodologia de Sistemas Suaves (MSF) pelo Grupo de Análise de Segurança de Sistemas Sociotécnicos (GASSST) em um problema complexo de segurança no Instituto de Pesquisas Energéticas e Nucleares de São Paulo, Brasil (IPEN-CNEN/SP). Baseando-se tanto em fundamentos teóricos, com base na documentação produzida por Peter Checkland e outros pesquisadores, quanto em experiências práticas, o estudo explora a abordagem da MSF para enfrentar desafios que envolvem fatores técnicos e humanos. Os principais resultados incluem a identificação das perspectivas dos principais interessados, o desenvolvimento de uma Figura Rica para capturar a complexidade do problema e a discussão de soluções potenciais. No entanto, a aplicação completa da SSM foi prejudicada devido às intervenções proativas da equipe da instalação, que resolveu o problema inicial antes que todas as etapas da SSM pudessem ser concluídas. O processo foi posteriormente interrompido por uma pausa induzida pela pandemia do SARS-CoV-2, durante a qual a equipe da instalação esteve ausente por 1 ano e 10 meses.

Імплементація механізмів і стандартів САП ЄС в Україні не матиме очікуваної ефективності без першочергового усунення притаманних їй інституційних проблем. Серед них: недооцінка в державній аграрній політиці громадських ініціатив; спотворення реальності, коли декларується підтримка середнього класу в сільській місцевості, а реально створюються умови до агрохолдингізації, монополізація земельних відносин і доступу до ресурсів та ринків; ігнорування занепаду сільських територій; недотримання стратегічної спадковості аграрної політики; безсистемність зусиль усіх рівнів галузевого управління в реалізації обраної політики.
Обґрунтовано теоретичний базис пізнання аграрного устрою і формування методології конструювання його перспективних моделей, розкрито фундаментально-прикладні основи структури, змісту й функціоналу модельних складових інституту аграрного устрою і державної аграрної політики. Встановлено, що теоретичною базою модельного підходу у сфері аграрної економіки є положення інституціональної теорії, теорії «команд управління» і національної ідеї. Доведено, що аграрний устрій за своїм змістом і характерними рисами є соціально-економічним інститутом. Розглянуто структуру аграрного устрою, проведено класифікацію та ієрархізацію його складових, визначено вимоги до їх опису. Розроблено алгоритми конструювання моделі аграрного устрою, запропоновано методологію і методи змістового наповнення її складових. Встановлено, що державна аграрна політика є невід’ємною частиною аграрного устрою, яка характеризується переважною більшістю його складових, визначальною серед яких є управління. Узагальнено дефініцію категорій: «неформальні інститути», «організації», «формальні інститути», «національна ідея», «візія», «політика», «реформи», «управління», «команди управління». Обґрунтовано новий зміст таких категорій, як «аграрний устрій», «модель аграрного устрою», «державна аграрна політика».
Підтверджено гіпотезу, що застосування модельного підходу до формування аграрного устрою вирішує наявні проблеми державної аграрної політики й політики сталого розвитку сільських територій і може розглядатися, серед іншого, і для формування політики воєнного й повоєнного устрою України.
Performance of AAP CPG for Ineligible Well-Appearing Febrile Infants Aged 8–60 Days
Authors: Knudson Melissa J. , Yaeger Jeffrey P.
Published: November 2024

BACKGROUND AND OBJECTIVES

The AAP’s Clinical Practice Guidelines (CPG) for febrile infants provides recommendations in evaluating well-appearing febrile infants aged 8–60 days at risk for invasive bacterial infections (IBIs; ie, bacteremia and bacterial meningitis). However, guidance remains limited for the infants excluded from (ie, ineligible for) the CPG. The objectives are to estimate the proportion of well-appearing CPG-ineligible febrile infants and to examine CPG performance in detecting IBIs for CPG-ineligible febrile infants.

METHODS

We performed a secondary analysis of single-site data collected for a prior study from 2011 to 2018. Infants were included if they were 8–60 days and well-appearing. We stratified IBI risk using age and CPG inflammatory marker thresholds for temperature, absolute neutrophil count, and C-reactive protein. We conducted analyses on CPG-ineligible infants and CPG-eligible infants. We estimated the areas under the receiver operating characteristics curve, sensitivity, and specificity of both approaches in detecting IBIs.

RESULTS

Of 648 infants, 22% did not meet CPG eligibility. Sensitivities for both analyses were 100% with specificities for CPG-ineligible and eligible of 38.1% (95% CI, 30–47) and 38.2% (95% CI, 33.9–42.6), respectively.

CONCLUSIONS

Strict adherence to the CPG may result in a substantial proportion of ineligible infants. Findings suggest that CPG-based approaches can maintain high sensitivities for all febrile infants, including CPG-ineligible infants. Future studies should examine the contribution of specific conditions (eg, preterm birth) to IBI risk.

The field of metallic glasses has been an active area of research owing to the complex structure–property correlations and intricacies surrounding glass formation and relaxation. This review provides a thorough examination of significant works that elucidate the structure–property correlations of metallic glasses, derived from detailed atomistic simulations coupled with data-driven approaches. The review starts with the theoretical and fundamental framework for understanding important properties of metallic glasses such as transition temperatures, relaxation phenomena, the potential energy landscape, structural features such as soft spots and shear transformation zones, atomic stiffness and structural correlations. The need to understand these concepts for leveraging metallic glasses for a wide range of applications such as performance under tensile loading, viscoelastic properties, relaxation behavior and shock loading is also elucidated. Finally, the use of machine learning algorithms in predicting the properties of metallic glasses along with their applications, limitations and scope for future work is presented.

RESUMO Objetivo: compreender os processos transicionais que incidem na adaptação de pessoas que convivem com limitações decorrentes da hanseníase. Métodos: pesquisa de abordagem qualitativa fundamentada nos preceitos da Teoria de Transição, mediada pela pesquisa-cuidado, com 24 pessoas com limitações decorrentes da hanseníase em um ex-hospital colônia, no Piauí. Foram realizadas entrevistas semiestruturadas. Procedeu-se a análise com suporte do software Iramuteq. Resultados: os pesquisados-cuidados vivenciaram os quatro tipos de transições, inclusive, experimentaram sentimentos de medo, preocupação, solidão, desesperança, culpa e tendência a esconder o diagnóstico. Desvelou-se rupturas e resignação, tendo a espiritualidade, a adaptação à nova situação de vida e aceitação, como condições facilitadoras do enfrentamento do processo transicional, com consequente melhoria da qualidade de vida. Considerações Finais: os processos transicionais tiveram significado positivo, visto que contribuíram na adaptação e no alcance da qualidade de vida.

RESUMO Objetivos: avaliar o manejo da dor no trabalho de parto. Métodos: estudo transversal realizado mediante revisão de prontuários e entrevistas pós-parto. Avaliaram-se prevalência e efetividade da analgesia. Resultados: a prevalência de analgesia não farmacológica foi 61,86% de 215 parturientes do Centro Obstétrico e 82,51% de 62 da ala liderada por enfermeiras. A prevalência de dor intensa, na Escala Visual Analógica, antes e depois da analgesia não farmacológica, foi de 92,16% para 64,04% (p=0,00) no Centro Obstétrico e de 85,96% para 52,63% (p=0,01) na ala das enfermeiras. A prevalência de analgesia farmacológica no Centro Obstétrico foi 15,81%, sem variação na dor intensa (p=0,57). O pedido de analgesia se associou à escolaridade (p=0,00) e à intensidade da dor (p=0,02). Conclusões: a analgesia não farmacológica melhorou a intensidade da dor. A prevalência de prescrição analgésica farmacológica foi inferior à de países desenvolvidos. O tratamento da dor precisa considerar preferências e necessidades das parturientes.

ABSTRACT Objective: To analyze the concept of “youth.” Methods: This is a concept analysis guided by the method proposed by Walker and Avant, operationalized through an integrative literature review. The search in scientific databases was carried out using the descriptors: youth; young; adolescence. To compose the literary corpus, 22 studies were selected. Results: Various factors were found in the antecedents that influence the separation of youth groups, contributing to the heterogenization of this population. The attributes include characteristics that comprise the formation of youth groups, especially the idea of shared experiences and social construction, as well as the consequences of the mentioned concept. After systematizing the variables, the analysis was conducted, highlighting the conceptions that influence youth. Conclusion: The study demonstrated the multifactorial complexity of the formulation of the concept of youth, highlighting various factors that contribute to this construction. For nursing, this conceptual field allows for an understanding of the population and effective engagement with this group.
