Relevance. An analogous recording of occlusal relationships (articulating paper, foil, etc.) is not sufficiently informative for precise determination of occlusal forces and sequence, which is related to the large inaccuracy, labour intensity and lower predictability of prosthetic treatment results. Aim. The study aimed to evaluate the effectiveness of fixed polymer prototype dental bridges in patients with tooth-bounded edentulous spaces and occlusal defects.Material and Methods. The randomized controlled study comprised two study groups: control (n = 21) and main (n = 21), which included the patients with tooth-bounded posterior missing teeth (second premolar and first molar). Prosthetic treatment corresponded to the conventional protocol in the control group. The main group had the missing teeth replaced with prototype prostheses and analogous-digital analysis of occlusal relationships. Intergroup effectiveness comparison rested on the integral occlusal score (IOS) data that considered scores received with T-scan 3 system (TekScan, USA). We also performed an intragroup comparative analysis of the periodontium condition around the abutment teeth using the Doppler ultrasound integral score (DUIS) at the stages before and after the treatment.Results. The study did not reveal statistically significant differences between the values of IOS in the control and main study groups before the treatment (p > 0.05). At the followed treatment stages, control group IOS values significantly differed from those of the main group, namely, by 65.35 % (p < 0.05) just before the replacement of the provisional bridge by the final prosthesis; by 76.19 % (p < 0.05) immediately after the final prosthesis delivery; and by 65.94 % (p < 0.05) one week after the delivery of the final prosthesis. The Doppler ultrasound integral score values reflected the statistically significant positive changes in the study groups (p < 0.05).Conclusion. Fixed polymer prototype prosthesis placement in patients with posterior tooth-bounded edentulous spaces and occlusal defects allowed us to increase prosthetic treatment effectiveness, improve microcirculation around abutment teeth, and harmonize the occlusion, decreasing the risk of possible damage to a ceramic bridge.

Сердечно-сосудистые заболевания остаются ведущей причиной заболеваемости и смертности во всем мире и в системе здравоохранения обуславливают самую высокую долю затрат. Патоморфологической основой ишемической болезни сердца в подавляющем большинстве клинических ситуаций является атеросклероз коронарных артерий. В последнее время множество исследований посвящено изучению ранней стадии атеросклероза – субклинического атеросклероза. Дестабилизация гемодинамически незначимых, бессимптомных атеросклеротических бляшек может привести к развитию инфаркта миокарда. В статье обсуждается распространенность, клиническая значимость необструктивного атеросклероза коронарных артерий. Отдельное внимание уделено шкалам стратификации сердечно-сосудистого риска. Обозначены современные методы диагностики коронарного атеросклероза, методы визуализации «нестабильных» атеросклеротических бляшек. В реальной клинической практике оценить «нестабильность» атеросклеротической бляшки не представляется возможным, поэтому сам факт наличия субклинического атеросклероза коронарных артерий позволяет отнести пациента к категории высокого и очень высокого риска.
Cardiovascular diseases remain the leading cause of mortality and morbidity worldwide and represent the highest proportion of costs in healthcare systems. In the vast majority of cases, the pathomorphological basis of coronary heart disease is coronary artery atherosclerosis. Many of the recent research have been devoted to the study of the early stage of atherosclerosis – subclinical atherosclerosis. Destabilization of hemodynamically insignificant, asymptomatic atherosclerotic plaques can lead to the development of myocardial infarction. The article discusses the prevalence and clinical significance of non- obstructive atherosclerosis of the coronary arteries. Special attention is devoted to the scales of cardiovascular risk stratification. Modern methods of coronary atherosclerosis diagnosis, methods of visualization of unstable atherosclerotic plaques are outlined. Considering that it is impossible to assess the instability of atherosclerotic plaque in real clinical practice, the presence of subclinical coronary atherosclerosis itself allows the patient to be classified as high and very high risk.
Supraventricular Tachycardia in Childhood: Classification, Diagnosis, Treatment
Authors: Строгий В.В. 
Published: September 2022

Наиболее распространенным видом нарушений ритма сердца у детей являются наджелудочковые тахиаритмии, составляющие в структуре до 95% от всех тахикардий у детей. Несмотря на почти столетнюю историю исследования различных тахиаритмий остается неизученным ряд вопросов: их распространенность, своевременная диагностика скрытых и латентных форм, определение сроков и показаний к проведению хирургического лечения, а также эффективности различных методов лечения. Данные проблемы обусловлены врожденными особенностями состояния проводящей системы сердца, которые в одних случаях могут способствовать бессимптомному течению или только наличию электрокардиографических признаков аритмии, а в других – сопровождаться выраженными признаками вегетативной дисфункции, нарушениями гемодинамики и повышать риск внезапной сердечной смерти. Нередко бессимптомное начало у детей, отсутствие гемодинамических проявлений приводят к запоздалой диагностике и несвоевременному лечению, что способствует более быстрому развитию аритмогенной кардиомиопатии, увеличению числа сложных аритмий перманентного характера (фибрилляция, трепетание предсердий), развитию сердечной недостаточности. Таким образом, актуальность данной проблемы обусловлена вопросами ранней диагностики, выбора сроков и методики лечения.
The most common type of cardiac arrhythmias in children are supraventricular tachyarrhythmias, which account for up to 95% of all tachycardias in children. Despite almost a century of research on various tachyarrhythmias, a number of issues remain unexplored: their prevalence, timely diagnosis of latent and latent forms, timing and indications for surgical treatment, as well as the effectiveness of various treatment methods. These problems are caused by congenital features of the state of the conduction system of the heart, which in some cases can contribute to an asymptomatic course or only the presence of electrocardiographic signs of arrhythmia, and in others they can be accompanied by pronounced signs of autonomic dysfunction, hemodynamic disorders and increase the risk of sudden cardiac death. Often asymptomatic onset in children, the absence of hemodynamic manifestations lead to delayed diagnosis and untimely treatment, which contributes to the more rapid development of arrhythmogenic cardiomyopathy, an increase in the number of complex arrhythmias of a permanent nature (fibrillation, atrial flutter), and the development of heart failure. Thus, the relevance of this problem is due to the issues of early diagnosis, the choice of terms and methods of treatment.

Background: The postpartum period is critical for women due to significant bio-psychosocial changes and the consequences of delivery.
Aims: The purpose of this study was to investigate the role of the use of contraceptives and other health-related factors in the risk of developing postpartum depression among women in Jordan.
Materials and methods: A cross-sectional, descriptive-correlational design was used to recruit 803 women using a convenience sample technique from the central district of Jordan. Data were collected on depressive symptoms, contraceptive use and type, and pregnancy health-related factors.
Results: Using binary logistic regression analysis, non-hormonal contraceptives and musculoskeletal pain were significant predictors (p<.05) of the risk of developing depressive symptoms in the sampled women (OR=4.1, 3.8; respectively). For the women in our sample, 24.9% (n=200) developed depressive symptoms. Most of those who felt depressed reported suffering from insomnia (50.0%] and baby blues (13.0%), while loss of appetite was reported by 33.0%. The analysis also showed that 51.0% (n=409) had used at least one method of contraception. Among those using contraceptive methods, 31.0% had only used hormonal contraceptives compared to 69.0% using non-hormonal forms.
Conclusion: Non-hormonal contraceptive use and musculoskeletal pain were found to be significantly associated with the risk of developing postpartum depressive symptoms. Family and reproductive health professionals need to emphasize the bio-psychological aspects of health for pregnant and postpartum women.
Interfacial effects on sensitization of chemically amplified extreme ultraviolet resists
Authors: Kozawa Takahiro 
Published: September 2022

Abstract
With the improvement of lithography resolution in the horizontal direction, the thickness of resist films becomes thin to avoid pattern collapse. The thinning of resist films is an important issue in the development of the next-generation lithography process. In this study, the interfacial effects on the sensitization of chemically amplified extreme ultraviolet (EUV) resists were investigated using a Monte Carlo method on the basis of their sensitization mechanism. The chemically amplified resist is a standard resist used for the fabrication of semiconductor devices. In chemically amplified resists, thermalized electrons reduce sensitizer molecules upon exposure to EUV radiation. The low-energy secondary electron dynamics at the vacuum-resist and resist-underlayer interfaces strongly affected the distribution of decomposed sensitizers. In particular, the resist bulk layer almost disappeared at 20 nm pitch in the specific cases. The control of interfaces becomes important in the development of the next-generation lithography process.

Der Einsatz von Peltierelementen bietet in der Temperierung von Prozessen und Bauteilen einen großen Vorteil gegenüber der in technischen Anwendungen üblicherweise eingesetzten Fluidkühlung. Sie pumpen Wärme rein elektrisch und stellen Temperaturen sehr schnell sowie präzise ein. Für eine neuartige, thermoelektrisch temperierte Motorspindel wurden in Kooperation zwischen dem Fraunhofer-Institut für Physikalische Messtechnik IPM und dem Institut für Werkzeugmaschinen und Fabrikbetrieb IWF der Technischen Universität Berlin zwei unterschiedliche Ansätze tubularer Peltierelemente simulativ verglichen. Die Ergebnisse zeigen, dass es mit beiden Konzepten möglich ist, induzierte Wärmeströme am Lagersitz abzuführen, um diesen auf eine vorgegebene Temperatur zu regeln.

The use of peltier modules offers a great advantage in the temperature control of processes and components compared to the common method using a fluid cooling. They can pump heat purely electrically and set temperatures very quickly and precisely. For a novel thermoelectrically tempered motor spindle, two different approaches of tubular peltier modules were compared simulatively in cooperation between the Fraunhofer Institute for Physical Measurement Techniques IPM and the Institute for Machine Tools and Manufacturing Technology of the TU Berlin. The results show that with both concepts it is possible to dissipate induced heat flows at the bearing seat and to control its temperature.

Einsatz von Schweißrobotern im Spezialschiffbau/Economic robot programming despite one-off production and highly reflective materials – Application of welding robots in shipbuilding
Authors: Zych Alexander , Lauer Sascha , Dryba Steffen 
Published: September 2022

Bei der Fertigung schiffbaulicher Unterbaugruppen werden im Universalschiffbau bereits meist Schweißroboter eingesetzt. Dagegen ist im Spezialschiffbau der Anteil automatisierter Produktionsanlagen deutlich geringer. Gründe hierfür sind unter anderem die Verarbeitung alternativer Materialien sowie die höhere Komplexität der Bauteile. Für solche Szenarien bietet die sensorbasierte Roboterprogrammierung in Verbindung mit spezieller 3D-Sensortechnik neue Chancen zum wirtschaftlichen Einsatz von Robotern.

In production of naval subassemblies the general shipbuilding industry usually uses welding robots. By contrast the proportion of automated production facilities in specialty shipbuilding is low. The reasons for this are the processing of alternative materials as well as higher complexity of component parts. Precisely for such scenarios, sensor-based robot programming in conjunction with special 3D-sensor technology offers new opportunities for the economical use of welding robots.

Das Softwaretool „SafeZone“ erlaubt die effiziente und zuverlässige Berechnung von Sicherheitsbereichen (Safe Bereichen) für komplexe schutzzaunlose Roboteranlagen, zum Beispiel im Karosseriebau und der Endmontage. Unter Berücksichtigung der realen Bewegungsbahnen und Geschwindigkeiten werden – im Gegensatz zum Status Quo – nur dort Gefahrenbereiche berechnet, wo auch Gefahren entstehen können. Das spart Platz und lässt Mensch sowie Roboter sicher näher zusammenrücken.

The „SafeZone“ software tool enables the efficient and reliable calculation of safety areas (safe zones) for complex robot systems without protective fences, such as car body construction and final assembly. Considering real motion paths and speeds, safe zones are calculated – in contrast to the status quo – only where hazards can occur. This saves space and allows humans and robots to move closer together safely.

Objetivo: Analizar la influencia del uso de los diversos tipos de mascarillas en la Frecuencia Cardiaca (FC) en adultos entre 18 a 60 años que vivan en el Perú en 2020. Materiales y Métodos: Se realizó un estudio de tipo experimental, analítico, prospectivo y transversal. Para la recopilación de datos fue mediante una encuesta virtual vía formulario de Google, con indicaciones para la correcta medida de la FC y en qué momentos realizarlo. Para el presente estudio se analizaron las posibles causas del aumento de la FC donde fueron elegidos 60 adultos asintomáticos en el rango de las edades de 18 hasta 60 años. Resultados: Se encontró que las variables tales como: estrés, depresión, ansiedad, alimentación, residencia y ocupación, chequeos médicos y actividad física, no afectan significativamente el aumento de la
FC. Además, se logró evidenciar un aumento de la FC en 3 momentos de medición,
del mismo modo que cuando se utilizó el tipo de mascarilla KN95 se pudo observar un aumento significativo en la FC y en el momento de reposo se vio un ligero aumento en la FC cuando el tipo de mascarilla era de tela. Conclusión: Se concluye que el uso de mascarilla tanto en reposo, después de realizar ejercicios físicos y posterior 5 minutos terminada la actividad física incrementa la FC, por el cual se puede notar que los factores mencionados no hacen un cambio significativo en la FC.

Efficacy of the drug Mercurid in the treatment of complications of COVID-19
Authors: Babinets L. S. , Velichko L. M. , Konovalova N. V. 
Published: September 2022

Modernity raises the most important questions for researchers: what will happen to patients who have undergone COVID-19? What complications threaten them? What happens to the immune system after this disease? To what extent do the changes caused by the virus disrupt the formation of protective immunity in the future?
The study found a causal relationship between SARS-CoV-2 infection, immune dysfunction, and the manifestation of chronic inflammatory diseases. Proven multitarget action of the new drug Mercurid, aimed at modulating the activity of several critical target proteins, such as CD3, CD4, CD8, CD25, CD38, CD54, CD95. On the one hand, this has reduced the severity of postpartum complications, and on the other - to increase the ability of the immune system to eliminate the virus from the body. The therapeutic efficacy of Mercurid was 75.1%.
The second research finding is that patients with a history of chronic inflammatory disease with a history of SARS-CoV-2 are more likely to develop impaired specific protective antibodies. This conclusion follows from the pathologically low level of CD4, CD8, CD25 and overexpression of CD38, ICAM-1, CD95, which indicates apoptosis of immune cells, lymphopenia and the formation of the phenotype of depleted T cells with activation of inhibitory receptor expression. Thus, for this cohort of patients, vaccination may be ineffective due to the presence of a compromised immune system. Accordingly, corrective multi-target immunotherapy targeting multiple target proteins critical to the development of long-term effective post-viral immunity to SARS-CoV-2 is an extremely important therapeutic task. Immunoprophylaxis can be performed both before and after vaccination, in order to achieve the maximum protective effect against the vaccine.
