: Additive manufacturing (3D printing) of fiber reinforced mortar/concrete has developed in the last decade as a potential alternative to the classic construction techniques that are used in civil and infrastructure applications. Compared to cast concrete, this technology offers several benefits, including faster prototyping and manufacturing, increased quality, reduced waste and high customization. In this article, there is presented a review of the 3D printing technologies, equipments, mixtures, reinforcements and trending applications that were carried out by various research teams. Also, there are discussed the mix design principles, the role of the superplasticizer and viscosity modifying agents and other factors that may modify the pumpability, flowability, extrudability and buildability of 3D mortar/concrete materials. An important part of this review is dedicated to the desideratum of developing and providing solutions for affordable houses. In this respect, the 3D printed constructions costs are substantially lower compared to the traditional alternatives, being in the same time environmentally sustainable and compatible with the latest European and international plans for climate change.

A modern, highly industrialized society cannot be achieved without having welded products as a basis for various industries such as food, medical, energy etc. By its nature, the welding process, considered as a special technological process, can lead to the appearance of imperfections that can negatively influence the behavior in operation. The paper aims to identify the interdependencies between imperfections and risks starting from the statistics obtained as a result of the quality examination of welded products, manufactured in an organization producing welded structures in the naval field, for a two-month period. Starting from an analysis using the Ishikawa method, causes and sub-causes leading to a reduced quality of welded joints were identified. The type of imperfections detected in over 20% of the examined products were pores, lack of melting and slag inclusions. For each type of imperfection, the risks and causes favoring the occurrence were identified, followed by the calculation of the inherent risk and a series of risk management actions. With the help of the Pareto analysis, the type of imperfection with the largest share was identified, which decisively influences the quality of the welded joints and, for which, immediate measures must be taken to reduce/eliminate it. The results obtained are presented in tabular and graphic form for easy understanding of the information presented.

Sodium alginate (SA) hydrogels reinforced with different concentrations (0, 0.01 and 0.05 wt.%) of Carbon Nanotori (CN) were characterised to determine their mechanical, tribological and cytotoxicity properties. For the mechanical tests, a crosslinking agent was added to obtain solid hydrogels, whereas for the tribological tests SA/CN hydrogel samples were analysed in a liquid state. In the cytotoxicity tests, the C6 cells proliferation was evaluated in the presence of CN at various dilutions. In the tensile tests the hydrated-hydrogel strips reinforced with 0.1 wt.% CN obtained an UTS of 44.43 MPa, representing an enhancement of 133% compared to the un-reinforced hydrogel. In the compression tests an increase of only 3.4% in the UCS was obtained with the addition of 0.05 wt.%. Tribological characterization showed an enhancement of up to 37% and 105% in seizure load (P oz) and load-carrying capacity (poz), respectively with 0.05 wt.% CN. The wear scar diameter at this concentration was reduced by ~19%. The results of the cytotoxicity tests confirmed that CN are not cytotoxic since they did not reduce C6 cell proliferation.

Prosthetics, a useful assistive device for patients having suffered trauma, are characterized by extreme customization, adaptability, and complex design. One of the basic principles of having a good prosthetic is an optimized design. With traditional CAD software, what a designer selects will be automatically used and applied to a solid model. However, CAD is not yet advanced enough to provide biomedical designers with a reliable customization framework. An aim of our work was to develop an upper-limb finger prosthetic device framework. The authors used an open-source software environment to develop an editable bespoke finger prosthetic. The implementation was done in the OpenSCAD programming language. The result is a rendering of a fully customizable finger prosthetic. The code base can be altered to generate new designs. The main contribution of the work is the script that provides an interface for prosthetic personalization. Such an approach may provide easy to use tools for orthotic and prosthetic technicians.

For the first time, the gear contacts of the precessional transmission were subjected to experimental research, on tribomodels, using metallic (steel 40Cr) and polymeric (POM) material couplings in various combinations: steel 40Cr/steel 40Cr, POM/POM and POM/steel 40Cr. The experiments were carried out in conditions without contact lubrication and lubrication (MULTIS EP2). The samples - model, in the form of cylindrical rollers were manufactured from tested materials, with the dimensions established from the conditions of ensuring the geometric and kinematic equivalence of the contact of the precessional gear. The research methodology consists in the loading of the contact in steps with the normal force (Fn) for periods of time determined by the stabilization of the tribological characteristics, especially the temperature T generated by the friction process. The tribological behavior of the contact was determined by the evolutions in time of: the frictional torque (Mf), the temperature in the contact area (T), the friction force (Ffr) and the summary friction coefficient (fƩ). The purpose of the research was to experimentally establish the influence of the geometry and kinematics of the contact on the friction process and the tribological behavior of the couplings of materials under study, in the operating conditions of the contact without lubrication and with lubrication. The results of testing on tribomodels, according to the methodology proposed by experimental research, can be successfully applied to the design stage of Precessional Transmission (PT) gears.

The paper presents a version of the improved string cutting installation for forming bricks with two hydraulic drives. A mathematical model of the movement of the traverse and the carriage of the installation, which require synchronous actions in the process of work, has been compiled. The dependence of the total force of the technological load and friction acting on the traverse on the movement parameters and tool geometry was obtained experimentally. The obtained dependence was used in the development of a mathematical model, represented by a system of nonlinear differential equations that were solved by the Rosenbrock method. A complex criterion for evaluating the efficiency of the automatic installation was formed and the values of the structural parameters of hydraulic drives were found, in which the errors of the geometric dimensions of the products and the power consumption will be minimal, and the productivity of the installation will be maximal.

One essential aspect of any CAD system, which has not been addressed adequately, is the capability to support the automatic placement of dimensions of a mechanical drawing. Today, even the most sophisticated CAD systems automatically place dimensions of mechanical drawings without strictly adhering to standard dimensioning rules (e.g., there are usually overlaps, repetitions and misplacement of dimensions). Therefore, the automatically generated dimensions are the starting point for a manual improvement of the dimension positions. In this paper we present a software system for the automatic placement of dimensions in mechanical drawings, incorporated into a commercial CAD system, which is efficient and places dimensions that comply with the basic drawing standards, assigns dimensions to all elements of a drawing, and does not produce redundant dimensions.

An important problem in the field of improving and developing equipment for determining the filtration properties of porous materials (in the example of skin products) is solved in the article. The importance of this study lies in the experimental determination of the permeability coefficient of the porous material. The filtration capacity of the hide samples and the coatings of the working rolls made of LASCH and BM cloths was experimentally determined in the article under industrial conditions. The results of the study of the filtration capacity of the skin product samples in the areas under consideration will make it possible to fulfill the requirements for the high-quality processing of skin materials. It was determined that the highest value of the filtration coefficient was observed in the "belly" section of the hide, the smallest value - in the "shoulder" section, and the average value - in the "butt" section, which is explained by the density of the structure of collagen fibers and pores; as the "belly" has a looser structure, the "shoulder" – the densest, and the "butt "is between them. The highest value of the filtration coefficient is observed with the LASCH cloths, and the smallest – with the BM cloth, which depends on the density of the structure of the considered cloth and the size of their pores. The LASCH cloth is made of polymer threads, while the BM cloth consists mainly of natural wool fibers and, to a lesser extent, of synthetic threads. A critical analysis of the results of an experimental study showed that the filtration capacity of a skin product decreases with an increase in the pressure of the tanning liquid.

Introduction: We aimed to clarify the therapeutic outcome of combination therapy using immune-checkpoint inhibitors (ICIs) and/or tyrosine kinase inhibitors (TKIs) for metastatic non-clear-cell renal cell carcinoma (nccRCC).
Methods: We have been retrospectively investigating the therapeutic efficacy and prognosis in 36 patients with metastatic nccRCC undergoing combination therapy using two ICIs, ipilimumab plus nivolumab (ICI-ICI), and ICI plus TKI (ICI-TKI), at Kobe University and affiliated institutions since 2018. Progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and adverse event (AE) were compared.
Results: The first-line regimens was ICI-ICI regimens in 26 cases and ICI-TKI regimens in 10 cases. The ORRs in the ICI-ICI and ICI-TKI groups were 34.6 and 30.0%, respectively (p=0.9433). The 50% PFS for the ICI-TKI group was 9.7 months, significantly longer than that for the ICI-ICI group (4.6 months, p=0.0499), and there was no significant difference in OS between them (p=0.3984). There was no significant difference in the occurrence rate of AE for below grade 2 (p=0.8535) nor above grade 3 (p=0.3786) between the ICI-ICI and ICI-TKI groups.
Conclusions: From our analysis of real-world data, a better outcome of PFS was expected in the ICI-TKI group compared with that in the ICI-ICI group, while there was no significant difference in OS or ORR.

In the history of mathematics, it is possible to find many extraordinary ideas, based on which new discoveries are currently being made. A great example is quantile regression. Currently quantile regression is often used in various fields of research in situations where it is necessary to use regression analysis and at the same time the prerequisites for using the least squares method are not met. In addition, quantile regression provides information that cannot be obtained directly from standard regression methods. The entire conditional distribution can be modelled in it, for example when it is applied in the performance evaluation of the examined pupils. In specific applications, it provides answers to important questions about modelling the tails of the conditional distribution. The article shows the advantages of its use in various areas of research and, on its own examples of application to pedagogical data, indicates the possibility of its use on data from the field of mathematics didactics.

The aim of the study is to find out which competences acquired in preparatory education are considered necessary by prospective kindergarten teachers for the development of children's mathematical pre-literacy as a component of children’s overall personality development. Quantitative research was carried out in 2022 on a sample of 175 students of the Bachelor's degree in Kindergarten Teaching at the Faculty of Education of Masaryk University in Brno. The results of the questionnaire survey showed that the research respondents consider support of the development of children's mathematical pre-literacy to be an important and necessary part of their professional activity. The importance of preparatory university education was identified. In order to be able to develop children's mathematical pre-literacy before they enter school education, students considered necessary, above all, to acquire pedagogical and specific methodological and diagnostic competences. They believed the previous knowledge of mathematics acquired at secondary school and university to be sufficient for professional work in kindergarten and they primarily required topics for the application of suitable activities.

The case study focused on inquiry-based learning in the combined teaching of mathematics and science in the fifth grade of primary school. In the article, we aimed to reflect on research activity in the context of the prepared curriculum reform in education in Slovak republic, which will deepen interdisciplinary relationships and learning in broader contexts. The research goal was to observe how fifth-grade students work in groups during research activities. We focused on how students gather data, evaluate the measured data using tables and graphs, and present their measured results. In groups, students looked for ways to measure the thickness of a tree trunk using an unconventional measuring tool - a string and evaluate the collected data in tables and graphs. Research question: do different types of trees have different trunk thickness? How does the thickness of a tree trunk relate to the age of the tree? The observation method was supplemented with a questionnaire for students to assess their group work, evaluate the lesson, and their relationship to the subjects of mathematics and science. From the evaluated data, we found that students had difficulties in the research process using the string and in constructing the graph.

Introducing critical and evaluative thinking into the school system requires patience, systematic approach and support from all stakeholders that may be encountered with a few problems. The introduction of critical and evaluative thinking requires well a chosen and systematic approach that takes into account the needs of pupils, teachers and the school environment. Effective introduction of these skills can provide students with tools for better understanding and solving complex problems in their life and work. The conditions for quality in education are a high-quality school system with a model of standard European financial security, high-quality teachers, modern content of education, but also a favorable climate in society for education, wisdom and creativity. School systems, which tend to permanently monitor the status of their success and efficiency, have set models of permanent monitoring of the main performance indicators of the system and mechanisms of flexible response to stagnant elements.

The main subject of our paper is the problem of didactic grasping of literary genres in the process of literary education at the lower secondary level. Pupils gradually encounter genological terms within of literary education and acquire basic knowledge about the types of literary genres and their genre codes. Through the designed activities, we pursue the adoption of these hard-to-grasp, abstract, genre codes and their features through experiential learning during the educational process. In the activities, we provide the pupil with concrete tasks, with the help of which they become familiar with the necessary knowledge and with the aesthetic component. By proposing activities, in this paper we try to deal with the didactic problem of teaching genre codes without forcing and preserving the artistic-aesthetic reading of literary texts.

In today's society, there are many factors that influence our life, upbringing, and education. Today, we are meeting with factors that we did not even know about until now, or we preferred not to know. One of these factors that greatly affected the educational process, its implementation and management was the period of the pandemic. The recent pandemic situation changed the basic direction of the school, which the school management had to manage both in relation to internal management processes and external processes. In this context, we carried out research, the most important findings of which we present in our paper. The goal of the research was to investigate and analyze how the school management dealt with the demands of the school's long-term mission in response to the presence of the Covid19 pandemic situation.

We deal with an optimal boundary control problem in a 1-d heat equation with Neumann boundary conditions. We search for a Neumann boundary function which is the minimum element of a quadratic cost functional involving the $H^1$-norm of boundary controls. We prove that the cost functional has a unique minimum element and is Frechet differentiable. We give a necessary condition for the optimal solution and construct a minimizing sequence using the gradient of the cost functional.

This study investigates the effectiveness of the cooperative script method in improving the ability of class VII students at Uswatun Hasanah Middle School to write formal letters. The research involved 15 students from the control class (VII A) and 16 students from the experimental class (VII B). Motivated by the observed challenges in analyzing official letter structures and linguistic conventions, the research aimed to address two key questions: 1) Is the cooperative script method effective for teaching formal letter writing to class VII students at Uswatun Hasanah Middle School?; and 2) What is the learning activity like when using the cooperative script method for writing formal letters in class VII at Uswatun Hasanah Middle School? Employing an experimental study design, data were collected through observations and pretest-posttest assessments. Statistical analysis indicated a significant improvement in the experimental group's performance (tcount = 2.960), supporting the conclusion that the cooperative script method effectively enhances formal letter writing skills among class VII students at Uswatun Hasanah Middle School.

Authors: Baihaki Ahmad
Published: January 2024

After SEMA No. 2 Year 2023, the opportunity to register interfaith marriages in Indonesia becomes difficult to do. This research aims to find out the extent of the implications of SEMA Law Number 2 Year 2023 on legal certainty regarding the legality of recording interfaith marriages in Indonesia. This research uses normative juridical research methods and is analyzed with philosophical, juridical, and sociological approaches. In conclusion, even though SEMA Number 2 of 2023 has been born, the question of legal certainty of the legality of registering interfaith marriages has not ended because there is still the issue of conflicting norms between the Law and its implementation

Цель – анализ влияния некоторых вариантов мультимодального анестезиологического обеспечения на функциональное состояние печени и маркеры ЭИ после НАХТ у пожилых онкологических пациентов, оперированных на органах малого таза. Материал и методы исследования. Выполнено рандомизированное проспективное исследование качества и эффективности различных вариантов мультимодальной анестезии (ММА) у 117 пациентов, перенесших в плановом порядке хирургические вмешательства по поводу рака шейки матки и рака яичников в возрасте 64 — 82 лет после нескольких курсов неоадьювантной химиотерапии. Выбор вариантов ММА с минимальными побочными последствиями, обеспечивает эффективное и качественное анестезиологическое пособие у пожилых больных получивших НАХТ. Включение в состав анестезиологического обеспечения лекарственных средств, обладающих гепатопротекторными и детоксицирующими свойствами, способствует снижению проявлений синдрома ЭИ, расхода опиоидсодержащих анальгетиков в интра- и периоперационном периоде

Цель исследования: улучшить результаты лечения больных перитонитом путем применения ранней энтеральной регидратации в послеоперационном периоде. Проанализированы истории болезни 68 больных с диагнозом перитонит различной этиологии. Проведен корреляционный анализ между сроками начала энтеральной регидратации и сроками восстановления перистальтики желудочно-кишечного тракта. Более ранняя энтеральная регидратация повышает частоту раннего восстановления перистальтики желудочно-кишечного тракта у больных перитонит различной этиологии. Однако, необходим более детальный анализ оптимальных сроков начала энтеральнойрегидратации в зависимости от причин развития перитонита.

The aim of the study: to improve the results of treatment of patients with peritonitis by using early enteral rehydration in the postoperative period. The case histories of 68 patients diagnosed with peritonitis of various etiologies were analyzed. A correlation analysis was carried out between the timing of the onset of enteral rehydration and the timing of restoration of gastrointestinal peristalsis. Earlier enteral rehydration increases the frequency of early recovery of gastrointestinal peristalsis in patients with peritonitis of various etiologies. However, a more detailed analysis of the optimal timing of the onset of enteral hydration is needed, depending on the causes of peritonitis.

рассматривается новая коронаровирусная инфекция (НКИ) с различных позиций. Особое пристальное внимание в ней отведено сопутствующей патологии и прочим факторам влияющим на исход заболевания. Цель исследования: улучшение результатов лечения больных новой коронаровирусной инфекции (НКИ) путем проведения трахеостомии, с учётом состояния их респираторной системы и других систем организма. Ранняя трахеостомия — это операция выбора для длительно вентилируемых пациентов с НКИ осложнённой пневмонией и/или ОРДС. Однозначно сказать какой из методов ПДТ или СХТ является лучшим пока довольно сложно. Большой отпечаток на выживаемость пациентов накладывает коморбидный фон. Возраст играет не последнюю роль. Методиками выбора были избраны ПДТ и СХТ. Однако нужно учитывать что они также имеют свои особенности и нужно предусмотреть осложнения и пути их избегания

Военная служба представляет собой специфичное направление деятельности, требующее определенных знаний, умений и навыков, грамотная реализация которых позволит добиться полного и своевременного выполнения служебных, служебно-боевых и боевых задач [3]. Выполнение задач военной службы предполагает адаптацию к условиям военного труда, которая имеет как физический (функциональный) характер, так и психологический, связанный с Резюме. Адаптация к военной службе у женщин в начальном периоде выполнения служебных задач обусловлена влиянием факторов гигиенической природы. К числу таких факторов относятся – климатические, пищевые, обеспеченность водой для питья и её качество, а также специфические факторы военного труда – микроклимат производственных помещений и психоэмоциональное напряжение, связанное с выполнением служебных задач. Влияние рассматриваемых факторов на протяжении свыше 12 месяцев приводит к срыву адаптации и формированию патологии мочевыделительной системы
America’s “Narrative of Combating the COVID-19 Pandemic” in “Post-truth” Context
Authors: Xu Shimi , Han Xiao , Zhang Xueru
Published: January 2024

Some US politicians and media, driven by the zero-sum Cold War mentality, ideological bias, and domestic political needs, have made no effort to politicize, stigmatize, and label the epidemic with the “post-truth” narrative logic of “promoting values and belittling the epidemic” in order to hide the institutional impotence and political incompetence exposed by the epidemic response and mitigate the impact of the comparison between “China’s governance” and “chaos in the United States.” The U.S. narrative of fighting COVID-19 was based on fabrications, fallacies, and hegemonic construction, which involved scapegoating others and assigning blame. The US “anti-epidemic narrative” is essentially a weapon to use fallacies to cut reality, fabricate history with lies, and suppress China with hegemony. The “anti-epidemic narrative” of the US is that it is dissatisfied with everything about China, regards China as being behind the times, and is hostile to both the Communist Party and Marxism. It is a denial of China’s strategy, direction, and system. The best method to combat the global public health crisis is to improve global public health governance, increase international cooperation against COVID-19, jointly build a “Silk Road for health,” and create a community of health for all people. Additionally, they contribute to revising the US “narrative against COVID-19.”
