Authors: Gunawan Yoga , Dialog Bias Lintang , Fitriana Diana
Published: October 2023

Land disputes are common in society, and the village head, as witnessed by the family, resolved the matter in congruent with the parties' will and good intention. Purpose to investigate the arrangement of land dispute resolution in Indonesia; and to investigate its application through consensus deliberation in villages to realize public order. Methodology an socio-legal approach, involving primary data gathered from the interview. Furthermore, the study was also conducted in Kuningan Regency. Findings in Indonesia, land disputes resolution have been completely regulated, ranging from laws to derivative regulations and is carried out through community discourse and consensus. However, deliberation method is more common than going to the court. The deliberations include bringing the parties together; if peace arrangements can be made, they will be made. It can, however, only function optimally if both sides (the family and the community) agree to deliberate. The method is thought to be more efficient in terms of time, cost, and mechanism.  Conclusion in the village, there are two procedures for resolving land conflicts through consensus deliberation: mediation and family negotiation. Recommendation at the village level, it is critical to provide a legal framework for deliberation so that the outcomes are more equitable and mutually beneficial to all parties

Published: October 2023

There have been changes in environmental management since the enactment of Law Number 11 of 2020 on Job Creation, particularly in bioremediation─upstream oil and gas Enterprises. It is intriguing since the process includes natural way of cleansing tainted oil in the water without harming the ecosystem. The study aims to examine the implementation of bioremediation in upstream oil and gas activities under Indonesian environmental law. The study also employed a normative juridical or doctrinal approach. According to the findings, bioremediation is being carried out under a profit-sharing contract with SKK Migas (Special Working Unit for Upstream Oil and Natural Gas Business Activities) acting as the implementing agency. The legal relationship position of an oil and natural gas mining company, specifically in bioremediation, is in the government and corporate accountability to carry out the program, referring to production sharing contracts─cooperation contracts and applicable statutory provisions. To summarize, all parties, including national and regional governments, communities, and oil and gas companies, must implement ecologically friendly protection such as bioremediation

Published: October 2023

This study aims to explore the intermediary function of organizational justice in the correlation between healthcare practitioners’ perceived perception of servant leadership and work engagement. A total of 412 health professionals from three state hospitals in Kocaeli province participated in this research. A survey was administered to the participants selected through the convenience sampling approach. The data from the administered questionnaires were analyzed using the SPSS Process Macro based on the bootstrap technique. The results provide empirical validation for the hypothesis that perceiving servant leadership positively impacts the level of work engagement. Moreover, the research has shown that perceptions of organizational justice influence this positive effect. Additionally, it has been found that perceiving servant leadership has a favorable influence on organizational justice, which, in turn, positively impacts the level of work engagement. Based on these findings, managers may adopt servant leadership behaviors to promote work engagement and enhance perceptions of organizational justice.

Objectives:

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is one of the most important diagnostic tools for investigation of suspected pancreatic masses, although the interpretation of the results is controversial. In recent decades, digital image analysis (DIA) has been considered in pathology. The aim of this study was to assess the DIA in the evaluation of EUS-FNA based cytopathological specimens of pancreatic masses and comparing it with conventional cytology analysis by pathologist.

Material and Methods:

This study was performed using cytological slides related to EUS-FNA samples of pancreatic lesions. The digital images were prepared and then analyzed by ImageJ software. Factors such as perimeter, circularity, area, minimum, maximum, mean, median of gray value, and integrated chromatin density of cell nucleus were extracted by software ImageJ and sensitivity, specificity, and cutoff point were evaluated in the diagnosis of malignant and benign lesions.

Results:

In this retrospective study, 115 cytology samples were examined. Each specimen was reviewed by a pathologist and 150 images were prepared from the benign and malignant lesions and then analyzed by ImageJ software and a cut point was established by SPSS 26. The cutoff points for perimeter, integrated density, and the sum of three factors of perimeter, integrated density, and circularity to differentiate between malignant and benign lesions were reported to be 204.56, 131953, and 24643077, respectively. At this cutting point, the accuracy of estimation is based on the factors of perimeter, integrated density, and the sum of the three factors of perimeter, integrated density, and circularity were 92%, 92%, and 94%, respectively.

Conclusion:

The results of this study showed that digital analysis of images has a high accuracy in diagnosing malignant and benign lesions in the cytology of EUS-FNA in patients with suspected pancreatic malignancy and by obtaining cutoff points by software output factors; digital imaging can be used to differentiate between benign and malignant pancreatic tumors.

On the possibility of determining allometric indicators of trees using satellite remote sensing data
Authors: Danilov Y. G. , Tahmazov Tabriz Mubariz oglu
Published: October 2023

In recent decades, the rapid development of remote sensing technologies has led to the development of various methods for determining the amount of aboveground biomass from satellite images. Regression equations were constructed linking fild estimates of aboveground biomass and vegetation indices obtained by remote sensing methods. Such studies make it possible not only to promptly monitor the state of vast forests, but also to solve the problem of assessing global carbon stocks on the planet. The purpose of the study is to create the foundations for the development of new methods for determining allometric indicators by remote sensing methods. The objectives of the study are to determine using remote sensing technologies (1) the total mass of trees of a forest consisting of n number of plots diffring from each other in the number and type of trees; (2) the total mass of a heterogeneous forest in which there is a certain functional relationship between normalized difference vegetation index (NDVI) and the number of trunks in a certain area; (3) the model relationship between NDVI and such allometric indicators as tree height (H) and crown diameter (CD). Research results: some problems of allometric measurements using remote sensing methods have been solved. A formula has been obtained for calculating the biological mass of trees in the forest using the values of the NDVI in individual forest areas; a similar problem for the case of a functional relationship between NDVI and the number of trunks in individual forest areas; the formula of the model relationship between NDVI and the product of such allometric indicators as tree height and crown diameter is obtained.

It offers research 2588 ceramic stamps found in Gorgippia, its chora and in the Semibratneje settlement as well.The working with originals, stored mainly in museus depots in Anapa and Krasnodar, made it possible to identify a large number of incorrect and inaccurate readings, whose improvements are proposed in this review.
Kytaion: reflections on the “small bosporan town”
Authors: Завойкин А.  А.
Published: October 2023

Kytaion was a small Bosporan town. It originated in the process of internal colonization by the Hellenes of the lands of Eastern Crimea. Literary sources, starting with the Periplus of Ps.-Scylax (3rd quarter of the 4th century BC), call it πόλις. At the same time, settlements similar to it in size and urban appearance in Strabo’s “Geography” (and in later sources) are attributed to the number of κῶμαι. (Some of them were probably founded as independent apoi kiai as a result of the Great Greek Colonization, but lost the polis’ status due to their entry into the power of the Spartokids.) In Russian historiography the term κῶμαι is usually translated and understood as “villages”, “rural settlements”, although it is polysemantic (settlement; the Dorian equivalent to Attic demes; urban area, quarter). The author of the article, relying on the testimony of Polyaenus (Strat. VI. 9, 3) about appointment by Leucon I to relatives of suspected treason of trierarchs in the management of κῶμαι, tried to prove that here we are not talking about individual “villages”, but about rural districts – the lowest district in the administrative-territorial system of the Bosporus state. From this angle, he analyzed information about these κῶμαι in Strabo, descended from writing of Artemidorus of Ephesus. As a result, the author concluded that, unlike the larger cities that retained elements of polis’ form organization (Pantikapaion, Phanagoria, Theodosia, Nymphaion, Kepoi, Hermonassa, Gorgippia), the so-called “small Bosporan towns” (Strabo’ κῶμαι) were mainly urban centers of territorial districts. The formation of such a structure dates back to the reign of Leucon I, although the beginning of this process must apparently be dated back to the last decades of his father’s life. Probably, these districts were named after their urban centers, and the demoticon of their inhabitants remained used, at least as early as the 3rd century AD (CIRB 942).

The article presents first results of studying paste compounds of Late Bronze Age handе made vessels from Panaghiya 1 settlement, Taman Peninsula. Vessels are dated to XIV-X C BC. The fragments of 17 vessels of Sabatinovskaya, Belozerskaya Cultures, with mixed features of Sabatinovskaya and Babinskaya Cultures and a vessel of unknown cultural background were researched. The study was carried out with the method of technological analysis, developed by A. A. Bobrinsky. It was specified that the main used resipe of paste composing was “clay + grog + dung infusion” (35,3 %). A temper of crushed rock (kwartz and kwartz sandstone) to it is noted in 17,7 % cases. Liman silty clay as a raw material for paste composing were used rarely (5,9 % cases in Sabatinov ceramic, 11,8 % cases in Belozerskaya ceramic, 5,9 % cases – Sabatinov-Babino vessels, 5,9% – a vessel of unknown cultural background). A composition “silty clay + crushed shell + organic liquid” was noted in 1 case (5,9 %) in the same vessel. The study of paste compounds of Late Bronze Age ceramic from Panaghiya settlement is expected to continue. In future it is planned to compare the outcome and the other sites materials of the same period from Taman Peninsula and, in the long run, from Crimea.
Late Roman Pontic Burnished Ware with incised decoration   from Bosporos and Chersonesos
Authors: Домжальский К. , Журавлев Д.В.
Published: October 2023

The paper describes Late Roman and Early Byzantine decorated fine ware vessels and fragments found on both sides of the Kerch Strait (city of Kytaia, Džurg-Oba necropolis and fortlet Il’ičevskoe), and in Chersonesos. The finds represent the recently identified group of fine ceramics called Late Roman Pontic Burnished Ware. They are characterized by very re fined, pale pinkish - light brownish clay containing some very fine flakes of mica and single lumps of lime of various sizes. The inside surface of the dishes is carefully burnished, producing a slight lustre, and contains elaborated decoration executed by delicate incising in dried clay after burnishing and before firing (sgraffito-like technique). The decorative compositions contain centrally placed big cross, in two cases flanked by palm-branches or cypresses of similar size, and in one case completed with representation of four birds between arms of the cross. The central compositions are surrounded by two concentric grooved lines accompanied in two cases by a long spiral scratched on their outside. The outer surface of the examined dishes was finished with less care, it has some turning marks and a dull appearance. The jugs with their burnished surfaces bear incised decoration in the upper part of their bodies. In both cases, it contains a friese composed of simple motifs such as palm trees and branches, threeleaf branches and rope patterns

Published: October 2023

There is currently no combination of quantum hardware and algorithms that can provide an advantage over conventional calculations of molecules or materials. However, if or when such a point is reached, new strategies will be needed to verify predictions made using quantum devices. We propose that the electron density, obtained through experimental or computational means, can serve as a robust benchmark for validating the accuracy of quantum computation of chemistry. An initial exploration into topological features of electron densities, facilitated by quantum computation, is presented here as a proof of concept. Additionally, we examine the effects of constraining and symmetrizing measured one-particle reduced density matrices on noise-driven errors in the electron density distribution. We emphasize the potential benefits and future need for high-quality electron densities derived from diffraction experiments for validating classically intractable quantum computations of materials.
Interphase formation on Al2O3-coated carbon negative electrodes in lithium-ion batteries
Authors: Vilá Rafael , Oyakhire Solomon , Cui Yi
Published: October 2023

Interfacial coatings show promise in stabilizing carbon negative electrodes for lithium-ion batteries. For example, applying nanometer scale Al2O3 coatings on carbon can improve fast-charging, low-temperature battery performance, and cycle life. However, the exact mechanism by which these interfacial films stabilize negative electrodes in lithium-ion batteries remains poorly understood. Here, we show that Al2O3 coatings on carbon negative electrodes undergo structural and chemical changes during the formation of the solid-electrolyte interphase (SEI) at low potentials. During formation, we find a conformal bilayer SEI on Al2O3-coated carbon electrodes, with each layer exhibiting distinct chemistry. Importantly, the SEI structure, chemistry, and uniformity differ substantially between Al2O3-coated carbon electrodes and uncoated carbon electrodes. Our results suggest that performance improvements are not solely due to the presence of the Al2O3 coating. Instead, we propose that the improved SEI structure, chemistry, and uniformity after formation are the key factors contributing to improvements in battery performance.

Applying electro-organic synthesis in flow configuration can potentially reduce the pharmaceutical industry's carbon footprint and simplify the reaction scale-up. However, the optimisation of such reactions has remained challenging and resource consuming due to the convoluted interplay between the various input experimental parameters. Herein, we demonstrate the advantage of integrating a machine learning (ML) algorithm within an automated flow microreactor setup to assist in the optimisation of anodic trifluoromethylation. The ML algorithm is able to optimise six reaction parameters concurrently and increase the reaction yield of anodic trifluoromethylation by >270% within two iterations. Further, we discovered that electrode passivation and even higher reaction yields could be achieved by integrating 3D-printed metal electrodes into the microreactor. By coupling multiple analytical tools such as AC voltammetry, kinetic modelling, and gas chromatography, we gained holistic insights into the trifluoromethylation reaction mechanism, including potential sources of Faradaic efficiency and reactant losses. More importantly, we confirmed the multiple electrochemical and non-electrochemical steps involved in this reaction. Our findings highlight the potential of synergistically combining ML-assisted flow systems with advanced analytical tools to rapidly optimise complex electrosynthetic reaction sustainably.
Continuous isolated noise sources induce repeating waves in the coda of ambient noise correlations
Authors: Schippkus Sven , Hadziioannou Céline , Safarkhani Mahsa
Published: October 2023

Continuous excitation of isolated noise sources leads to repeating wave arrivals in cross correlations of ambient seismic noise, including throughout their coda. These waves propagate from the isolated sources. We observe this effect on correlation wavefields computed from two years of field data recorded at the Gräfenberg array in Germany and two master stations in Europe. Beamforming the correlation functions in the secondary microseism frequency band reveals repeating waves incoming from distinct directions to the West, which correspond to well-known dominant microseism source locations in the Northeastern Atlantic Ocean. These emerge in addition to the expected acausal and causal correlation wavefield contributions by boundary sources, which are converging onto and diverging from the master station, respectively. Numerical simulations reproduce this observation. We first model a source repeatedly exciting a wavelet, which helps illustrate the fundamental mechanism behind repeated wave generation. Second, we model continuously acting secondary microseism sources and find good agreement with our observations. Our observations and modelling have potentially significant implications for the understanding of correlation wavefields and monitoring of relative velocity changes in particular. Velocity monitoring commonly assumes that only multiply scattered waves, originating from the master station, are present in the coda of the correlation wavefield. We show that repeating waves propagating from isolated noise sources may dominate instead, including the very late coda. Our results imply that in the presence of continously acting noise sources, which we show is the case for ordinary recordings of ocean microseisms, velocity monitoring assuming scattered waves may be adversely affected with regard to measurement technique, spatial resolution, as well as temporal resolution. We further demonstrate that the very late coda of correlation functions contains useful signal, contrary to the common sentiment that it is dominated by instrument noise.

La búsqueda en las mejoras de producción de café en el departamento de Cundinamarca ha generado un creciente interés en el desarrollo de metodologías de evaluación de parámetros de calidad en el proceso de cultivo y postcosecha del grano. En el contexto tradicional, el análisis de calidad se desarrolla mediante inspección visual y procesos químicos, los cuales pueden resultar inoportunos e insuficientes. En este sentido, las técnicas de reconocimiento de imágenes actuales se destacan por ser herramientas rápidas, confiables y económicas para la evaluación de calidad y detección de irregularidades en productos alimenticios, ya que permiten caracterizar y cuantificar de forma simultánea distintas propiedades fisicoquímicas de una muestra a través de su firma espectral. Se presenta aquí un enfoque basado en técnicas de reconocimiento de imágenes y visión por computador para la identificación de características y objetos en archivos RGB. El desarrollo de este proyecto tiene un enfoque innovador ya que la caracterización computacional de imágenes se presenta como una solución para la caracterización de parámetros de interés en alimentos. Además, es una metodología de fácil y rápido acceso, que permite desarrollar diagnósticos preventivos y estudios en campo con la proyección de optimizar los tiempos de producción para satisfacer la demanda alimentaria.
La pertinencia de la contextualización y conceptualización del entorno, para la intervención de sistemas desde la ingeniería
Authors: Fuentes Cotes Milena
Published: October 2023

En la actualidad, cobra cada vez más importancia desde las diferentes disciplinas, saberes y áreas del conocimiento, hacer un análisis profundo y crítico sobre las formas de relacionamiento que tienen los seres vivos con el entorno. Es reconocido mundialmente que, los modelos económicos hegemónicos, los estilos y formas comunes de producción, algunos de los hábitos adquiridos socialmente y los métodos, tecnologías y técnicas que se utilizan para explotar la naturaleza, han sumergido a la población mundial en un camino insostenible que está dejando de lado la calidad de vida y el bienestar de las comunidades, convirtiendo el objetivo de lograr un desarrollo sostenible y sustentable en una verdadera utopía. Desde la ingeniería, se plantean varios retos frente a la transformación de las actividades y procesos realizados por el hombre, para la adaptación y transformación de su entorno de acuerdo con sus “necesidades”, que requieren de análisis holísticos de los sistemas a intervenir, partiendo de la contextualización y conceptualización de estos. Lo anterior se convierte en un asunto de gran relevancia, cuando se plantea como necesario para dejar de lado posibles visiones reduccionistas de la industria, la empresa y los gobiernos, que no permiten analizar sistémicamente los impactos ambientales causados en la naturaleza. Teniendo en cuenta lo anterior, es relevante como ingenieros empezar a consolidar un aprendizaje a partir de los conceptos y principios básicos de la biología y la ecología, específicamente de la comprensión de las dinámicas (sinergias) del entorno, para aproximarnos a la comprensión del funcionamiento de los sistemas a intervenir y de cómo esas dinámicas presentes en la naturaleza generan las bases para la vida, para el crecimiento económico y la estructuración de la sociedad. Todo lo descrito hasta este punto, pretende invitar a reflexionar sobre el proceso de formación de individuos como profesionales de la ingeniería, debido a la clara relación existente entre el conocimiento consolidado de los sistemas a intervenir vs. el impacto positivo que posiblemente pueda generar un desarrollo de ingeniería. Todo artefacto tangible o intangible producto de un ejercicio metodológico de esta disciplina, permitiría evidenciar una implementación más positiva, cuando se ha diseñado a partir del entendimiento, comprensión y conocimiento de las variables involucradas, desde las relaciones e interacciones presentes entre ellas e incluyendo las dinámicas que determinan el funcionamiento de los diferentes procesos que conforman tal sistema.

La accesibilidad geográfica es catalogada como un parámetro de competitividad entre regiones y cadenas productivas, importante en la planificación espacial del territorio, en la conexión entre orígenes y destinos. Se ha definido como la facilidad de alcanzar un lugar específico desde otro lugar y el grado en que el desarrollo espacial permite a los individuos alcanzar un lugar en el espacio. El Departamento de Nariño, Colombia se ha caracterizado por producir uno de los mejores cafés especiales del país, de excelente calidad y atributos diferenciales, pero ha tenido problemas para su comercialización y distribución, resultado tanto de la ausencia de red de infraestructura de transporte y mantenimiento de estas, como por falta de equipamientos estratégicos logísticos para su almacenamiento, afectando su competitividad. Esta investigación tuvo como objetivo evaluar la equidad espacial a partir de los niveles de accesibilidad territorial de los puntos de compra de cafés especiales de las cooperativas de la región hacia el centro de distribución existente de mayor capacidad, ubicado en la capital del Departamento y tres escenarios propuestos mediante el modelo de localización de centro de gravedad y Minisum. El análisis se dividió en 5 fases metodológicas, iniciando con la caracterización de la estructura de red existente, implementación de métodos de localización, modelación de la accesibilidad territorial (línea base equipamiento actual y equipamientos propuestos), cuantificación del ahorro generado en las zonas productoras (puntos de compra) de los tiempos de viaje y análisis de cobertura, finalmente la evaluación de la equidad espacial. Como principal resultado se obtuvo que los escenarios propuestos, generan un impacto positivo en las diferentes zonas de producción, generando ahorros de tiempo de viaje de hasta 11,85 %. Objetivamente, se pudo mostrar que es posible evaluar las condiciones de accesibilidad e impacto generado de determinadas actuaciones en las cadenas productivas agrícolas.

En las últimas décadas, debido al alto incremento en la contaminación ambiental, se nos ha venido educando acerca del adecuado manejo, control y reciclaje de desechos. Particularmente, la industria del tabaco es una de las responsables de numerosos daños de este tipo, no sólo durante el proceso de producción, sino también durante y después de su consumo. “Una colilla de cigarrillo tarda más de una década en descomponerse naturalmente y contamina hasta 50 litros de agua. Genera un efecto ecotóxico que no sustenta la vida y amenaza a los peces, algas y organismos acuáticos del país”. En consecuencia, el problema de contaminación generado por las colillas de cigarrillo se debe básicamente a tres factores: 1) la gran cantidad de colillas producidas en el mundo: cerca de 5,6 billones por año que equivalen a 845.00 toneladas, de las cuales 94,9 millones (16 toneladas) se producen específicamente en Bogotá; 2) la lenta descomposición o degradación (de 1-2 años); y 3) la formación de lixiviados debido a la posibilidad de transferir los contaminantes retenidos al suelo, cuando son arrojadas en exteriores y al agua. De igual manera el sector agroindustrial de frutas en particular de la piña genera una la gran cantidad de residuos convirtiéndose en un gran problema no sólo ambiental sino económico. Por lo tanto, el desarrollo de nuevos productos cosméticos usando como activos productos naturales y respetuosos con el medioambiente es una de las tendencias actuales. Por lo anteriormente descrito el objetivo del trabajo fue diseñar un cosmético ecoamigable usando como activo bromelina de residuos de piña (Ananas Comosus) y celulosa de colillas de cigarrillo como excipiente. En este trabajo las colillas de cigarrillo fueron recolectadas en cuatro puntos en las playas de la ciudad de Cartagena (Bolívar) (10°25′25″N 75°31′31″O). Tras la recolección, se procedió a separar los elementos de las colillas de cigarrillo (tabaco, filtro, papel) con el fin de continuar el proceso de aprovechamiento a cada material.

Published: October 2023

In Central America, childhood cancer is one of the leading causes of death. It is also a significant disease burden to health systems, with social and economic implications for families. The World Health Organization (WHO), the Executive Secretary of the Council of Ministers of Health of Central America and the Dominican Republic (SE-COMISCA), the Pan American Health Organization (PAHO), and St Jude Children’s Research Hospital are working collaboratively to strengthen the health system’s response to childhood cancer in Central America and the Dominican Republic. This collaboration’s primary objective is to support the development of national pediatric cancer plans for each country in the subregion and improve overall survival rates and quality of care for children with cancer through a more comprehensive universal health coverage package. This collaborative effort has led to: (i) the development of childhood cancer national action plans; (ii) the launch of awareness and promotion campaigns; (iii) the design of childhood cancer educational material for children and their families; and (iv) a platform for professionals working in childhood cancer to share good practices and successful experiences. The countries of the subregion together with PAHO and St Jude Children’s Research Hospital are working to develop standardized evidence-based clinical practice guidelines on childhood cancer for the region. This brief communication reports on this collaborative work.
Christian Leadership in a Secular Culture
Authors:   , Graham Campbell
Published: October 2023

This thesis analyses the experience of Christian leaders in New Zealand within three distinct contexts: primary school principals, National Party politicians, and management within a small to medium-sized business. Through detailed interview research, I show that these Christians express deep anxiety about the challenges they face as leaders within an increasingly secular society. Their contexts significantly shape their capacity to respond, with some affording much more room for manoeuvre than others. I argue that attention to Christian leadership helps illuminate the contours of a secular culture in New Zealand. This secular culture is influenced by state policy but is also enacted and sustained through everyday quotidian interactions, which discipline the space for public expression of religion. While this secular culture marginalises Christian voices within the public sphere, I also point to potential openings for moving beyond closure into dynamic public conversations about religion.
The Intervention Effect of Full-Responsibility Midwifery in Conjunction with Guided Labor Accompaniment on Maternal Birth Outcome
Authors: Zhu Hongjuan
Published: October 2023

Objective: To investigate and analyze the intervention effect of full responsibility midwifery with guided labor accompaniment on maternal birth outcomes. Methods: 68 cases of labor and delivery from January 2021 to December 2022 in Yancheng Dafeng People’s Hospital were selected and grouped into the study group (n = 34) and the control group (n = 34). The pregnant women in the control group were in full-responsibility midwifery nursing intervention, and the pregnant women in the study group were in full-responsibility midwifery with guided labor accompaniment. The duration of labor, the rate of spontaneous delivery, the incidence of adverse pregnancy outcomes, and satisfaction with nursing care between the two groups were recorded and evaluated. Results: The duration of labor in the study group was lower than that in the control group (P < 0.05); the rate of spontaneous delivery in the study group was higher than that in the control group (P < 0.05); the incidence of adverse pregnancy outcomes in the study group was lower than that in the control group (P < 0.05); and the nursing care satisfaction in the study group was higher than that in the control group (P < 0.05). Conclusion: Full-responsibility midwifery with guided labor accompaniment can shorten the duration of labor, increase the rate of spontaneous delivery, reduce the incidence of adverse pregnancy outcomes, and achieve higher satisfaction of maternal care, which is of value for popularization and application.

Authors: Zhang Shuxue
Published: October 2023

With the advancement of the economy, the construction of roads and bridges has assumed a crucial role in thedevelopment of China’s highway transportation system. The interplay between the design and construction technologies of road bridges is pivotal, as it directly impacts the subsequent operation and maintenance phases. Although the design and construction techniques for continuous girder transitions have been progressively improving, challenges still persist. This paper takes the example of the continuous girder design for the T-structure (75 m + 75 m) of the Xintai Highway Crossing Yanzhou-Shijiusuo Railway Separation Interchange Project and delves into an analysis of the structural design calculations for the bridge transition, the transition structure’s design, and critical considerations during construction. The findings presented here can serve as a valuable reference for similar project designs.

Катализаторы селективного окисления аммиака до молекулярного азота играют важную роль в борьбе с загрязнением окружающей среды автомобильными и промышленными выбросами. В работе было проведено исследование катализаторов селективного окисления аммиака на основе Pt/TiO2, модифицированных калием. Катализаторы Pt/TiO2 были получены пропиткой коммерческого носителя TiO2 (Degussa, P25 Aeroxide) нитратным предшественником платины, с последующим нанесением небольших количеств калия с варьированием природы предшественника: КОН, КNO3, KCl. Применение комплекса физико-химических и кинетических методов (порошковая рентгеновская дифракция, рентгеновская фотоэлектронная спектроскопия (РФЭС), температурно-программируемая десорбция NH3 (ТПД-NH3), температурно-программируемая реакция NH3+O2 (ТПР-NH3+O2)) позволило рассмотреть влияние промотирующей добавки на свойства катализаторов. По данным рентгеновской дифракции для образцов наблюдалось образование дисперсных частиц платины с размером области когерентного рассеяния не более 5 нм. Данные РФЭС указывают на изменение степени окисления платины при варьировании предшественника калия. Было показано, что применение хлоридного предшественника калия способствует повышению селективности по молекулярному азоту в области температур до 200°С. Данные ТПД-NH3 позволили проследить изменение кислотных свойств поверхности образцов и провести сопоставление с их каталитическими характеристиками в реакции окисления аммиака.

Published: October 2023

This paper deals with a generalized aspect of multipliers for the pair (Lω1, Lωp) of Beurling spaces. Using the Fourier transform related to a Beurling weight, we give a characterization of the aforementioned multipliers. We also prove the identification of the space of the multipliers for the pair (Lω1, Lωp) with the Beurling space Lωp when 1< p<∞.
Enhancing Concept Inventory Analysis by Using Indexes, Optimal Histogram Idea, and the Likert Analysis

Since the introduction of the Force Concept Inventory (FCI) in 1992, the CI tests have been widely used for measuring conceptual knowledge and for studying teaching issues in almost all disciplines and levels of study. A standard concept inventory analysis includes the design of a qualitative test, adequate realization of testing, calibration procedure, and comprehensive analysis of its findings. Usually, the CI test calibration is carried out through the Rasch sociometric technique, which is also used for calculating crucial indicators of knowledge such as item difficulties, students’ abilities, and many more. Whereas the quality of the tests’ design can be guaranteed by using certified and professional CI tests, the statistical adequacy of the testing merits critical attention before going on to the final step of the analysis. Also, the analysis of CI outcomes can be advanced by contemplating auxiliary tools and complementary techniques. In this framework, we propose to enforce the test index validity requirement for qualifying the CI outcomes as local or global. Specifically, the conclusions of CI analysis are acceptable for the whole population from which the sample has been extracted if the test's indexes comply with the validity requirements provided by the index theory. In the case when test indexes are out of validity range and re-conducting them is impractical for some objective circumstances or research specifics, we suggest injecting some new records into the existing one or mixing the data gathered from different samples until the new indexes are in the desired range. Using this methodology, we have reviewed our previous FCI tests, which were initially intended to demonstrate the impairment of learning in the physics discipline triggered by online learning during the pandemic closure. Through this renormalization procedure, we obtained a credible assessment of the understanding of mechanics and electromagnetism in high school students who followed online lectures during the pandemic closure. Also, by using indexes’ validity as an auxiliary tool, we identified that for measuring the knowledge of electromagnetism in students enrolled in branches where physics is a basic discipline, a shortened version of the BEMA test was a better instrument than the corresponding shortened EMCI test. Next, we used the optimal histogram idea borrowed from distribution fitting procedures to identify the natural levels of students’ abilities for solving a certain CI test. Another intriguing proposal presented in this work consists of combining an ad-hoc Likert scale assignment for usual errors in physics exams with the FCI designation of the basic commonsense confusion in mechanics for identifying their pairing features in common exams. We believe that the methods proposed herein can improve CI analysis in more general senses. Doi: 10.28991/HEF-2023-04-01-08 Full Text: PDF
