Published: June 2024

Lack of motivation to learn students results in them being less focused on learning and less active during the learning process, which impacts low student learning outcomes, especially in the science and science learning process. A lack of innovative teaching materials mostly causes this or tends to be monotonous. Therefore, supportive teaching materials that are attractive in form and based on appropriate learning models are needed so that students are enthusiastic about learning and can think critically. One medium that is a solution is to use CTL-based E-Worksheet. This research aims to develop a CTL-based E-Worksheet for grade 4 elementary school science content. This research is a development research type with the ADDIE model. The research subject is CTL-based E-Worksheet media on class 4 science content. Data collection uses expert test instruments and trials. The data analysis technique calculates the percentage score for validation assessments and user responses. The research results show that the development of a CTL-based E-Worksheet for grade 4 science content meets very valid criteria from the quality aspect, with a detailed score of 93.775% from media experts, 95% from learning design experts, and 94.6% from learning content experts. The results of the student response test showed an increase from the pretest results, with an average score of 34.8%, to an average score of 84.8 on the students' post-test results. Based on these results, the CTL-based E-Worksheet teaching materials that have been developed are suitable for application in learning.

The purpose of this paper is to introduce a new strategy to improve the convergence and efficiency of the class of domain decomposition known as Schur complement techniques related to interface variables for the simulation of mechanical, electrical and thermal problems in presence of cross points. More precisely, we are interested not only in domain decomposition with two equal parts having the same physical properties but rather in more general splitting components. It is known that in the first case, the optimal convergence with good pre-conditioner is obtained in two iterations and the problem is still challenging in the second case. The primary goal then is to fill part of the gap in such problem domain decomposition techniques and to contribute to solve extremely difficult industrial problems of large scale by using parallel sparse direct solver of the multi-core environment of the whole system and handling each part of the system independently of the change of the mesh or the shifting of the mathematical method of resolution and subsequently, we treat the interface as boundary conditions. The numerical experiments of our algorithm are performed on few models arising from discretization of partial differential equations using Finite Element Method (FEM).
Study of the wastewater treatment process during the operation of the bio-filter in the periodic mode
Authors:   Saint Petersburg State University of Architecture and Civil Engineering, Feofanov Yu. A.
Published: June 2024

The article presents the study results of the performance of the experimental unit with a plastic film load working in a periodic mode of wastewater supply at high initial loads. The kinetics of the process and changes in the efficiency of wastewater treatment over time are considered. As it was revealed, an increase in the load on the bio-filter caused a corresponding increase in the rate of contaminants` removal over the entire range of tested loads, while biomass saturation with the substrate was not observed. This characterizes a high adaptive capacity of the attached biomass to high salvo loads. It is shown that the process of organic contaminants` removal on bio-filter under the conditions of periodic tests has a staged character, indicating the possibility of bio-filter operation in the modes of incomplete and complete biological treatment of wastewater, as well as for nitrification processes. The beginning of the nitrification process and its speed depended on the load on the bio-filter for organic pollution and the degree of wastewater treatment, and the change in the rate of nitrification was autocatalytic. An indicator of the non-oxidizable part of organic pollutants in wastewater is taken into consideration, which can be used in the evaluation of the bio-filter performance.

The article presents the results of the study of heat fields and temperature gradients on the surface of shungite containing concrete under electrode heating during cold water concreting. There has been established a possibility of increasing the efficiency of electrode heating during winter concreting and achieving a more uniform temperature in the entire volume of the concrete structure, which prevents a decrease in quality due to the introduction of a ground conductive mineral shungite, an active mineral additive (AMA) and a plasticizing additive (PA) into the concrete mixture. Practical application of this method helps to increase duration of concrete electrode heating, reduce time of ultimate strength development of reinforced concrete structures and accelerate construction process in general.
El amanecer de la nueva España y el más pequeño de los «grandes eventos»: Madrid ‘92
Authors: Giurco Matteo
Published: June 2024

En 1992, la firma del Tratado de Maastricht y la creación del IBEX-35, el índice bursátil que agrupa a los 35 valores de mayor capitalización de España, sellaron la entrada del País ibérico en la economía globalizada. El vuelco económico vino acompañado de una copiosa cosecha de grandes eventos deportivos y culturales, destinados a subrayar la ansiada conquista de la modernización del Estado: los Juegos Olímpicos de Barcelona, ​​la Expo de Sevilla y los actos del Quinto Centenario del descubrimiento de América contribuyeron a realizar un auténtico annus mirabilis en la historia de la España contemporánea.
Al mismo tiempo, Madrid se convirtió en el escenario de una de las grandes políticas culturales comunitarias, pudiendo reclamar el título de capital europea de la cultura. El objetivo de la ponencia es analizar este importante evento, cuyo papel en la nueva configuración del imaginario colectivo nacional ha sido hasta ahora descuidado por la historiografía.

Published: June 2024

Entre los elementos que subyacen en la integración europea, frecuentemente olvidamos la trascendencia de eventos internacionales clave en la determinación de la política común. El caso del apartheid sudafricano responde a esta clase de sucesos, al entrar a valorar el complejo proceso de la política europea para la consolidación de una respuesta común. En este artículo valoramos la confluencia entre la evolución de las sanciones emanadas por la CEE hacia el apartheid desde mediados de la década de los ochenta en la composición del nuevo marco legislativo común en materia exterior, consolidado con la firma del tratado de Maastricht en 1992.
Gestión de las políticas de asilo en la Unión Europea: ¿crisis de refugiados o crisis de derechos?
Authors: Yela Uceda Mercedes
Published: June 2024

La Unión Europea se ha enfrentado a numerosos retos en materia de asilo/refugio en los últimos años. La crisis de refugiados ha supuesto un verdadero reto para los Estados miembros de la Unión Europea desde el aumento de llegadas en los años 2015 y 2016, en los que las solicitudes de asilo/refugio superaron un millón.
Las políticas de migración y asilo, el deber de cumplimiento del principio de solidaridad, el exceso de carga en los Estados miembros, el colapso de solicitudes y el aumento de acuerdos con terceros estados, constituyen un verdadero desafío para el respeto de los derechos de los refugiados en la Unión Europea.
El uso de una metodología exploratoria documental junto al apoyo de la jurisprudencia nos ayudará a demostrar las debilidades de las políticas de asilo y refugio para una gestión eficaz de las llegadas de los solicitantes de asilo y nuestra hipótesis de trabajo, la ineficaz protección de los derechos de los refugiados y las vulneraciones del Derecho Internacional de los Refugiados.

Preservação de tecido urbano e adensamento
Authors: Luccas Luís Henrique Haas
Published: June 2024

O estudo examina o avanço da preservação do patrimônio construído para tecidos urbanos formados por bens que não dispõem da excepcionalidade necessária ao tombamento, utilizando para este propósito o caso específico de Porto Alegre. A proteção de conjuntos através de inventários patrimoniais se justifica por apresentarem características arquitetônicas de interesse sociocultural, configurando espaços referenciais da memória coletiva e a própria identidade urbana, que se encontram ameaçadas por planos diretores descaracterizadores. Essa modalidade alternativa recente de preservação tem seu uso restrito à esfera municipal, já que o Instituto do Patrimônio Histórico e Artístico Nacional e os órgãos patrimoniais estaduais visam proteger obras de categorias correspondentes às suas respectivas hierarquias através do tombamento. Entretanto, a medida necessária agravou o conflito existente na preservação de bens culturais privados, destacadamente naqueles “menores” e mais numerosos, pela impossibilidade da substituição destes por novas edificações financeiramente vantajosas. O trabalho discute o tema, propondo o “adensamento” de área construída das edificações atingidas como recurso para amenizar os entraves existentes, utilizando como exemplo possível o caso contrastante de Montevidéu exposto de forma sucinta.

Published: June 2024

The work presented is the result of the implementation of diffraction measurements: phase composition and stresses resulting from additive manufacturing process of nickel superalloy Inconel 718 components print. With the help of diffraction methodologies, the key parameters from the point of view of the quality of prints and their strength were determined. The existence of individual phases in the material after printing was demonstrated, and the surface variation of the stress values was presented, showing its dependence on the geometry of the printed part – measurements were made at various points on the surface of samples with different geometries. In addition, the variation of the stress level was shown depending on the distance of the measurement point from the build platform on which the additive manufacturing process was carried out. Components were printed on the surface of a single build plate in order to study the effect of printing differently oriented samples with respect to the platform geometry, as well as the mutual effect of the temperature of samples printed first on the stress state of elements printed in subsequent steps of the procedure, and the effect of the temperature of elements printed later on the rate of temperature decrease, and consequently on the stress state, of elements printed first.
Perceptions of patients, nurses, other healthcare workers, and general hospital managers about the content and challenges of transforming the clinical pathway into an integrated clinical pathway: a qualitative pilot study
Authors: Zupančič Vesna , Erjavec Karmen
Published: June 2024

Aim. Hospital health care of a patient represents a part of the patient’s “journey” through the healthcare system and as such is not delivered independently, but in a personalized integrated manner. To achieve a better outcome of personalized medical health care of patients in hospital, it is necessary to systematically transform the existing clinical pathways (CPs) into integrated clinical pathways (ICPs). The aim of the study was to investigate stakeholder’s perceptions of the content and barriers to transforming CPs into ICPs on the example of a general hospital in Slovenia. That is how we obtained microdata for systemic measures at the level of general hospitals in Slovenia.

Material and methods. The cross-sectional study used a qualitative method with interviews and focus groups with patients, nurses, other healthcare workers and managers working in ICPs for chronic kidney disease and hip replacement in a typical Slovenian hospital.

Results. The results showed that ICPs could be divided into five basic phases. In all phases, additions to the existing CPs in order to turn them into ICPs were necessary, which was an additional burden, especially for the nurses.

Conclusions. Personalized health care through ICPs is patient-centered, shorter, holistic, coordinated, continuous, of higher quality for patients and sustainably more efficient for providers.

Published: June 2024

Goal: This study aimed to conduct a thorough review of the scientific literature, meticulously identifying the diverse approaches, attributes, and logical schemes used to understand the intricate dynamics of organizational culture.   Theoretical framework: The principles of meta-analysis were used for the bibliographic survey to contemplate all theories and theoretical fields contained in studies on organizational culture so that a faithful representation of its conceptual scope could be obtained.   Method: The conceptual bibliographic method was used in its four stages: formulation of the problem, data collection in international scientific databases, analysis and organization of the data, and consequent generation of answers to the investigation's guiding questions.   Results and discussion: The results indicated the existence of 27 distinct approaches, which can be organized into seven semantic groups. One hundred-two attributes were also found, which generated ten semantic groups. The logic found is that organizational culture manifests itself through sharing its members' mental content and configuring physical and extraphysical spaces.   Implications of the research: These findings shed new light on organizational culture by characterizing it as an extraphysical phenomenon that manifests itself physically, confirming new theoretical fields about organizations, such as spiritual and interpsychic dimensions.   Originality/Value: This study contributes to the understanding of organizational culture by showing that rites, myths, beliefs, values, and others are merely distinct forms of manifestation of a phenomenon that is intrinsically and extrinsically non-material.

White sponge nevus (WSN) is a rare autosomal-dominant disorder of the non-keratinized mucosa, characterized by a thickened white edematous mucosa whose surface appears irregular, wrinkly, or spongy. It affects mainly the oral mucosa. The histopathological examination demonstrates hyperparakeratosis, acanthosis with intracellular edema and vacuolization over the prickle cell layer, and eosinophilic perinuclear condensation. The currently accepted etiology is a mutation of the keratin 4 and/or keratin 13 genes. We present a case of WSN diagnosed in a 30-year-old white male patient with white corrugated bilateral lesions on the buccal mucosa that extended beyond the occlusal plane. A biopsy was obtained, and the histological presentation included superficial parakeratosis, prominent acanthosis of the squamous epithelium, and areas with prominent intracellular edema, which confirmed the diagnosis. No treatment was necessary other than patient counseling and initial 6-month follow-up consultation. His attending dentist was informed of the diagnosis, and further follow-ups were recommended.

In this study, the formation and growth of coating microstructure was studied and reported based on APS and EB-PVD deposition mechanism with the change in spray angle. A NiCrAlY bond coat with 8YSZ ceramic coat was applied by APS and EB-PVD deposition onto the Inconel 718 with the variation in spray angle. The investigation was divided into microstructural analysis and mechanical properties to determine the effect of different deposition mechanism and its variation in spray angle. The results obtained show that the APS with 60° spray angle has more presence of defects, followed by APS 90° and EB-PVD samples. The APS avg. grain size varies between ~ 400 to 800nm, whereas EB-PVD in between ~ 150 to 300nm. The EB-PVD with 90° spray angle results in low porosity i.e. 18.12 % followed by APS 90°, EB-PVD 60°, and APS 60° spray angle, respectively. The low porosity results in high compressive residual stress than medium and high porosity. The avg. Raman shift for EB-PVD 90° spray angle i.e. low porosity is 1.86 cm-1, for medium i.e. APS 90° and EB-PVD 60° is 1.33cm-1 and 1.53cm-1 respectively, and for high porosity is 0.93cm-1. The 90° spray angle showed better microstructural and mechanical properties compared to 60°.

Authors: Aggarwal Shipra
Published: June 2024

Performance behaviours of oil-lubricated sector shape pad thrust bearings incorporating the variable depth’s pockets/textures have been presented. The variable depth texture comprises of combination of grooves and pockets. Fixed depth pocket, variable depth pocket (depth of the pocket reducing towards the exit) and combination of fixed and variable depth pocket with the fixed and variable depth grooves have been considered in the present investigation. With the aim to improve the performance parameters of fixed pad thrust bearing, the effect of texture parameters such as pocket/groove depth, the circumferential extent of texture and different combinations of variable depth’s pocket and grooves have been investigated. Substantial improvement in the performance parameters (minimum film thickness and coefficient of friction) has been achieved in the presence of proposed textures having variable depths of micro-geometries.

Finally, the correlation between the parameters of the heat treatment – the structure – behavior at cavitational erosion compared to those of the untreated thermal alloy was determined.
Effects of Adding Graphite to Epoxy Resin on its Mechanical Properties and Mild-to-Severe Wear Performance at its Heat Distortion Temperature
Authors: Eayal Awwad K.Y.
Published: June 2024

In this study, epoxy/graphite composites were fabricated based on different weight fractions (0, 3, 6, and 9 wt.%) of graphite powder for bearing applications. The mechanical and tribological properties were assessed. Adhesive wear tests covered the severe regions, where the interface temperature (IFT) exceeded the heat distortion temperature (HDT) of the epoxy. Graphite additions improved elastic modulus and hardness but decreased fracture strain and toughness of the composites. The tribological behaviors in the mild wear region were improved as the graphite content increased. In the mild wear region, the increase in graphite additions showed a good improvement by reducing the specific wear rate (SWR) and coefficient of friction (COF). In the severe wear region, the neat epoxy and higher graphite concentrations exhibited a dramatic increase in SWR, whereas the lowest addition of 3 wt.% exhibited good wear performance. For epoxy, the reason was that IFT exceeded its HDT, while the aggregation of graphite particles was the main reason in the case of higher graphite concentrations. SEM examinations showed severe wear signs—high ploughing and fracture—when IFT exceeded the HDT. However, by reducing the IFT, graphite additions did not show such severe wear features due to the accelerated heat dissipation.

An analytical complex study of metal-polymer (MP) helical and spur gears by a new author's analytical method was carried out. The influence of the helix angle on the contact pressures in the engagement, the teeth wear, and the durability of the MP gears of different polymers has been established. MP gears with a pinion made of carbon steel (0.45% C) and gear made of basic polyamides PA6, PA66, and their composites with the following fillers: fiberglass (PA6+30GF), carbon fiber (PA6+30CF), molybdenum disulfide (PA6+MoS2), and oil filled cast polyamide (PA6+Oil) are studied. According to the developed procedure for determination of the angles of engagement parity change, it is shown that there is two-one-two-pair or three-two-three-pair engagement depending on the helix angle. Quantitative and qualitative regularities of changes in the initial maximum contact pressures and their reduction due to tooth wear over the time from the moment of the entrance of teeth to engagement up to their exit from it are established. In particular, at a helix angle of β = 10°, the contact pressures reduce to 33% compared to spur gears. The linear wear of the gear polymer tooth profile at selected points of engagement and different helix angles has been investigated, and the influence of the pressure angle on it is shown. It is established that its regularities of change during the engagement phase are the same for all polymeric materials studied. The durability of transmissions is calculated, and its comparative evaluation is given. At the helix angle β = 5°, a slight increase in durability is achieved compared to spur gears, and at β = 10° the durability of MP gears increases by about 1.5 times for all polymeric materials studied.

Authors: Семенов Микола , Єсіпова Ольга
Published: June 2024

У статті проаналізовано поняття “компетентність”. Визначено, що воно не має єдиного тлумачення. Компетентність може бути розглянута як комплексна характеристика особистості, яка включає в себе як зовнішні, так і внутрішні аспекти, необхідні для успішної діяльності та взаємодії з навколишнім середовищем. Дано власне трактування поняття професійна компетентність майбутнього офіцера як інтегральна якість особистості, яка включає в себе готовність виконувати професійні завдання, що досягається у ході набутих знань, умінь та навичок під час професійної підготовки, готовність до самовдосконалення, саморозвитку і саморефлексії.

РОЗВИТОК ФАХОВОЇ ПЕРЕДВИЩОЇ ОСВІТИ ЗА УМОВ ВОЄННОГО СТАНУ
Authors: Вінтоняк Оксана
Published: June 2024

У статті на основі аналізу ухвалених Верховною Радою, Урядом, МОН України документів з’ясовано тенденції розвитку фахової передвищої освіти в період режиму воєнного стану, від 24 лютого 2022 р., коли розпочалася повномасштабна агресія РФ проти України, до початку 2024 р. У цьому періоді виокремлено три стадії: першу (24 лютого – кінець квітня 2022 р.) визначено як стадію стратегічної невизначеності; другу (кінець квітня – серпень 2022 р.) – як стадію адаптації до умов воєнного стану; третю (серпень 2022 р. – початок 2024 рр.) – як стадію стабілізації та подальшого вдосконалення функціонування системи фахової передвищої освіти. Проаналізовано науковий дискурс щодо її ролі та місця у системі національної освіти.
INICIOS DE LA LEXICOMETRÍA Y LA LINGÜÍSTICA COMPUTACIONAL EN ESPAÑA.
Authors: García Marcos Francisco J
Published: June 2024

La investigación documenta el arranque de estos dos instrumentos en España, la lexicometría y la lingüística computacional, fundamentales para el desarrollo de la lingüística descriptiva y la lingüística aplicada. Recpnstruye esa etapa, que arranca del Centro de Cálculo de la Universidad de Madrid, en el que paricipa Juan Alfredo Bellón, cuya participación concluye en su novedosísima tesis sobre Luis Cernuda. A partir de ese momento, se convierte en una referencia en la Universidad de Granada, con continuidad a través de otros autores, hasta el punto de considerar ambas herramientas en el análisis lingüístico.
عَلاماتُ الإِعرابِ - دراسة ألسنية في المصطلح والوظيفة - (( جمع وتقعيد وشرح وتطبيق ))
Authors: عُميـري علي العُميري إِبراهيم أَحمد
Published: June 2024

العلامات الإعرابية تنحصر في تسع علامات فقط ، هي:  { الضمة ، والفتحة ، والكسرة ، والسكون ، والألف ، والياء ، والواو ، والنون ، والحذف ، وقد استعملت العربية خمس علامات منها تشترك في الدلالة على وجهين إعرابيين في حالات معينة هي { الفتحة والكسرة والألف والياء وحذف النون }، فميزتْ لنا أربع عشرة حالة إعرابية كلها لا تخرج عن حالات الرفع والنصب والجر والجزم ، فالضمة للرفع ، والفتحة للنصب وجرّ الاسم الممنوع من الصرف ، والكسرة للجرّ }، وهو ونصب جمع المؤنث السالم، والألف لنصب الاسماء الستة ورفع المثنى، والياء لـنصب المثنى وجمع المذكر السالم وجرّهما ، وحذف النون لنصب الأفعال الخمسة وجزمها .
     إِنَّ هذه المصطلحات { الفتحة ، والضمة ، والكسرة } قد أخذتْ أسماءها من أوضاع الفم وما يشتمل عليه من أعضاء أخرى تحدد مخارج الأصوات عند النطق بها وبما يلتحق بها من الحركات ، فوسم الأول ضمّاً لأنّه ينشأ من ضمّ الشفتين، ووسُم الثاني كسراً ؛ لأنّه ينشأ من انجرار اللّحي الأسفل إلى الأسفل انجراراً قوياً ، وسُمّي الثالث فتحاً لأنّه يتولد من مجرد فتح الفم  ، ثُـمَّ صارت هذه المصطلحات رمزاً لمقامات الإعراب والبناء، ثُـمَّ توضحتْ هذه المصطلحات وزاد تحديدها فيما بعد نتيجةً حتميةً لتوسع الدرس الصوتي واتساع مباحثه، أمّا مصطلح السكون فمأخوذ من سكون آلة النطق ؛ لأنّه ضد الحركة ، والحركة إنّما سمّيت حركةً لأنّها تحرك الحرف وتجتذبه إلى الحرف الذي هو من جنسها ،
    ولا بد من الإشارة إلى أنَّ الحركات ( العلامات ) التي على أَواخر الكلم { الفتحة والضمة والكسرة } هي صور وأجزاء من أَحرف العلة ، وتفعل فعل تلك الأحرف في توجيه الموقع الإعرابي للمفردة([i]) ، وأَنَّ { السكون } هو : هو اختفاء الحركة على الحرف الساكن.
ذرائعية ثيمة الرحيل في فراقية ابن زريق البغدادي من التشكيل إلى التصوير
Authors: الحارثي نايف بن عبد العزيز
Published: June 2024

تعد النظريات النقدية الحديثة طوق نجاة  للنصوص الأدبية وفهمها، فالذرائعية مذهب فلسفي أدبي يعتمد على الحقيقة بعد التجربة الإنسانية، وابن زريق البغدادي الشاعر المشهور والمغمور في آن، أنتج لنا نصاً حياً، تتعاضد فيه الفكرة مع الأسلوب والصور الشعرية؛ لتكون لنا جسداً حياً ناطقاُ يشف لنا عن معاناة الغربة وأحوالها وأهوالها، وهو الذي سأعمل على استنطاقه من النص اليتيم، بعيداً عن الدراسات التقليدية التي تحاول تحليل العمل الأدبي وفق الأدوات الكلاسيكية، ولذا سيتناول هذا البحث فكرة الرحيل والغربة من منظور لساني بحثاً عن التشكيل، والتصوير، والقيم الجمالية، وكيفية توظيف الصور المبنيّة على المجاز توظيفاً فنياً مكثفاً؛ للكشف عن العمق الوجداني، والبعد الروحي للشاعر، في إطار شعري واحد يتمثل في الصورة المنتمية إلى عالمه النفسي.
