Published: December 2022

Abstract
Background and study aims Procedural sedation and analgesia (PSA) by trained non-anesthesiologist physicians and/or nurses is often performed during endoscopic procedures. Discharge from the recovery area after monitored observation is frequently based on fixed time parameters or subjective clinical assessment. In this study, the effect of implementation of the Aldrete score on recovery time after procedural sedation was analyzed in a real-life setting.
Patients and methods A prospective observational study of patients undergoing procedural sedation and analgesia during gastroscopy, colonoscopy or endoscopic ultrasound was performed. All procedures were randomly included to represent a real-life situation with different endoscopists, recovery nurses, endoscopy systems and indications. After a first observation period, all endoscopy nurses were trained to implement the Aldrete score when discharging patients, followed by a second observation period.
Results During the first observation period, the average time spent in the recovery area was 59 ± 22 minutes after procedural sedation. After implementation of the Aldrete score, the recovery time decreased significantly to 47 ± 25 minutes (P < 0.01) with identical doses of procedural sedation and analgesia. The decrease in time was between 19 % and 35 % for the different endoscopic procedures.
Conclusions Implementation of the Aldrete score after procedural sedation and analgesia significantly reduces the time spent in the recovery area. The score can be used to safely implement a discharge policy that provides more efficient and standardized management for an endoscopy service.

ZusammenfassungDurch unverzüglich eingeleitete Wiederbelebungsmaßnahmen können Überlebensraten im Fall eines Herz-Kreislauf-Stillstands deutlich erhöht werden. Ersthelferalarmierungs-Apps benachrichtigen
per Smartphone-Ortung registrierte Personen, sodass sie Erste-Hilfe-Maßnahmen einleiten können, bis der reguläre Rettungsdienst eintrifft. In deutschen Leitstellen will man zwar zunehmend
derartige Anwendungen einsetzen, es bestehen aber häufig datenschutzrechtliche und insgesamt juristische Bedenken. Die Notwendigkeit der Berücksichtigung des Datenschutzes ergibt sich aus
der EU-Datenschutzgrundverordnung (DSGVO). Bei Gesundheitsdaten gelten zusätzlich zur allgemeinen Rechtfertigungspflicht für Datenverarbeitungen besonders strenge Regeln, die differenziert
zu betrachten sind, wenn ein Einverständnis aufgrund des betrachteten speziellen Notfall-Settings nicht möglich ist. Die Rechtfertigung der Verarbeitung kann sich in diesen Fällen aus Art. 6
Abs. 1 lit. c)–e) i. V. m. Art. 9 Abs. 2 lit. c) DSGVO ergeben. In diesem Feld fehlt bisher jedoch eine grundsätzliche Einordnung, wie man herstellerunabhängig und über einen „Datenschutz
durch Technikgestaltung“-Ansatz derartige Applikationen umsetzen kann.Der Beitrag erörtert dazu jeweils mit juristischem Hintergrund, aber auch anhand einer praktischen Lösungsskizze die Aspekte der Ortung der Ersthelfer per App, die Übermittlung der
personenbezogenen Daten von Patienten an die Ersthelfer und die Rückübermittlung von Daten hinsichtlich des Einsatzes durch die Ersthelfer an die Leitstelle. Zudem wird auf die rechtliche
Stellung und die Haftbarkeit der freiwilligen Ersthelfer eingegangen.In Summe kommen die Autoren zum Schluss, dass gegen die Ortung der Ersthelfer keine Bedenken bestehen, wenn sie mit deren Einwilligung, unter Beachtung des Grundsatzes der Datenminimierung
und dem Aspekt der Vergröberung geschieht und natürlich die technische Lösung professionell umgesetzt wird. Im Punkt der Übermittlung der personenbezogenen Daten von Patienten an die
Ersthelfer bestehen in Summe ebenfalls keine Bedenken, sofern auf den Anwendungsfall für besonders zeitkritische Notfälle geachtet wird. Auch die Rückübermittlung von Einsatzdaten durch den
Ersthelfer scheint möglich. Eine Strafbarkeit der Beteiligten nach § 203 StGB scheitert spätestens aufgrund des sog. „rechtfertigenden Notstandes“ nach § 34 StGB. Die vorliegende Arbeit ist
ein praktischer rechtlicher Leitfaden und kann Grundlage für eine Konzeption und Implementierung einer solchen Lösung sein.
Fit Accuracy of Complete Denture Base Fabricated by CAD/CAM Milling and 3D-Printing Methods
Authors: Charoenphol Kanyakorn , Peampring Chaimongkon 
Published: December 2022

Abstract
Objective Digital complete denture fabrication can be accomplished by either milling or three-dimensional (3D)-printing approach in which minimal distortion during processing contributes to effective denture base adaption, which leads to good denture retention. The purpose of this study was to compare the fit accuracy of milled and 3D-printed complete denture bases.
Materials and Methods The reference edentulous maxillary arch model was scanned to generate virtual denture bases using computer-aided manufacturing software that exports as standard tessellation language files. Denture bases were constructed using a milling and 3D-printing technique using digital light processing method (n = 10). Intaglio surfaces of denture bases were scanned and superimposed on the reference model. The fit accuracy was quantified as root mean square error and evaluated statistically using independent t-test comparisons with a significance level of 0.05.
Results Milled denture bases were significantly more accurate in adaptation than 3D-printed dentures in the overall intaglio area and primary bearing area of denture bases. 3D-printed denture bases demonstrated significantly greater accuracy in adaptation than milled denture bases in the peripheral/posterior palatal seal area.
Conclusion Milled denture bases fit better in the overall and primary stress-bearing areas than 3D-printed dentures, while 3D-printed dentures appeared more accurate in the peripheral seal area, which had a minor undercut that is not suitable for using milling technology.

Published: December 2022

Abstract
Objective Atraumatic restorative treatment (ART) may be beneficial for disadvantaged populations with no or limited access to dental services. This study aimed to evaluate the survival rate of single-surface ART restorations in primary posterior teeth in children with high caries risk.
Materials and Methods This study was conducted in six rural areas of the Republic of Kosovo, and 100 children aged 3 to 8 years participated in the study. Information was obtained from each parent/guardian regarding their children, such as sociodemographic characteristics, general health, dental history, dietary habits, oral hygiene, and fluoride exposure. The reduced Cariogram was used to estimate the risk of caries in the participants based on the seven factors specified in the program, and all the provided information were collected and entered in a computer program of the Cariogram. A pediatric dentist, accompanied by two assistants, performed 100 ART restorations in school settings using high-viscosity glass-ionomer cement (Fuji IX) following the nine steps of the ART procedure. The restorations were evaluated at 3, 6, 9, and 12 months using the ART restoration criteria.
Statistical Analysis Percentages, mean value, standard deviation, mean interquartile range, and difference test between arithmetic mean values were used to analyze the research results.
Results Review of the average of reduced Cariogram showed that the majority of children, 72%, were at high risk of developing caries, with only 28% having a good chance of avoiding caries in the future. A total of 77% of the children in the study had never visited dentists before due to poor economic conditions and the lack of dentists in the area. The success rates of ART restorations performed in single-surface cavities in primary teeth were very encouraging, with more than 97% success rates after a 1-year follow-up period.
Conclusion Our results demonstrate that ART is efficient, affordable, and practical for the treatment of single-surface cavities in primary posterior teeth. Owing to its low price and atraumatic nature, ART can potentially help disadvantaged children in Kosovo access dental care.

Published: December 2022

AbstractMigraine, a primary headache disorder is a chronic and complex neurological disease that affects millions of people worldwide, impacting their quality of life. It is one of the most common reasons why individuals seek the advice of their physician, and is one of the most common referrals seen in the offices of general neurologists and headache specialists. In the past decade, there has been robust research on not only the pathophysiology of migraine but in the efforts to treat and, importantly, prevent. The introduction of calcitonin gene related peptide antagonists (CGRP-A) have opened new doors for preventive treatment options. OnabotulinumtoxinA (BoNTA) has remained a staple in the treatment of chronic migraine with data emerging with combination therapy. Neurostimulation has offered additional nonpharmacologic approaches to migraine treatment. In addition to lifestyle and behavioral modifications, these have changed the landscape of migraine prevention.

Abstract
Objective The benefits of mechanical thrombectomy (MT) in patients with acute posterior circulation stroke remain unclear. Currently, there is no evidence from randomized control trials to show the safety and effectiveness of MT in patients with posterior circulation stroke. This study was to evaluate the treatment outcomes of MT in posterior circulation stroke patients enrolling in our hospital during 2010 to 2020.
Materials and Methods Between January 2010 and December 2020, 66 patients with acute posterior circulation stroke underwent MT. Data collected and analyzed included demographics, comorbidity, National Institutes of Health Stroke Scale (NIHSS), procedure time, site of occlusion, presence of posterior communicating artery (PCoA), endovascular technique, and modified Rankin Scale (mRS). Good clinical outcome was defined by mRS at 2 or less at 90 days after MT.
Statistical Analysis Variables with normal distribution were reported with mean ± standard deviation, meanwhile those with nonnormal distribution were demonstrated with median and range. Fisher's exact test for categorical variables or Mann–Whitney U test for continuous variables was performed. Multivariate logistic regression analysis with binary logistic regression method was used analyze the association between the prognosis factor and good outcome. Statistical significance was defined when p-value less than 0.05.
Results The mean age of patients was 65.2 years with male predominance. The median NIHSS was 18.5. Successful recanalization (modified thrombolysis in cerebral infarction 2b-3) was achieved in 61/66 cases (92.42%) and postprocedure symptomatic intracerebral hemorrhage occurred in 5/66 cases (7.60%). Successful recanalization with good clinical outcome was obtained from 30 of 61 cases (49.18%); it was also associated with distal basilar artery occlusion (p = 0.035) and PCoA patency presence (p = 0.024). Our study showed the correlation between good treatment outcomes with initial NIHSS less than 20, intravenous recombinant tissue-type plasminogen activator, pre-MT magnetic resonance imaging Q5 brain, and contact aspiration MT technique.
Conclusion MT is beneficial to patients with posterior circulation stroke. A good clinical outcome was significantly associated with distal basilar artery occlusion and PCoA patency presence within a group of successful recanalization.
Negative Pressure Wound Therapy in the Head and Neck: A Summary of Uses and Application Techniques
Authors: Liebman Robert Michael , Hanubal Krishna S. , Dziegielewski Peter T. 
Published: December 2022

AbstractNegative pressure wound therapy (NPWT) has had an expanded role in the management of complex wounds including its increasing use for complex wounds in the head and neck region. Challenges for use in the head and neck region include variations in surface topography and the proximity of sensitive mouth, nose, ear, eye, and tracheal openings. Despite these challenges, NPWT has been used in the head and neck immediately following free flap surgery, to prepare wounds for skin grafting or local flaps, to treat orocutaneous and pharyngocutaneous fistulas, to treat necrotizing and deep neck space infections, to temporize and palliate, and to treat chronic wounds with exposed bone and hardware among others. This review demonstrates the proven track record of successful uses of NPWT in the aforementioned scenarios, provides suggestions to improve efficacy, as well as an algorithm for use in certain clinical situations.
Impact of two-child policy on female employment and corporate performance: Empirical evidence from Chinese listed companies from 2010 to 2020
Authors: Leng Aolin , Kang Fuli 
Published: December 2022

AbstractIn 2013, the ‘Decision of the Central Committee of the Communist Party of China on Some Major Issues Concerning Comprehensively Deepening the Reform’ initiated the ‘selective two-child policy’, which allowed married couples to have two children if one of the parents was a single child. In the Fifth Plenary Session of the 18th Central Committee of the Communist Party of China in 2015, a decision was made to implement the policy that a couple can have two children; in 2016, the universal two-child policy was fully implemented. This study used female employment data disclosed by Chinese listed companies from 2010 to 2020, constructed a two-way fixed-effect model of time and industry, and empirically tested the impact of the two-child policy on female employment and corporate performance. The empirical test revealed that the higher the proportion of employed female workers, the better the firm’s performance. Expanding the scope of the two-child policy exhibited no reduction in the proportion of female employment, but weakened the positive effect of hiring female employees on corporate performance. Specifically, we found that firms with higher rates of female employment exhibit lower costs, and this low-cost effect disappears with the expansion of the scope of the second-child policy. This indicates that the economic benefits of female employment for firms result from wage discrimination. This study provides a theoretical and practical basis for safeguarding women’s reproductive and fair employment rights and promoting sustainable social development.
A model construction and measurement method for tooth surface deviation of spiral bevel gear based on a one-dimensional probe

Published: December 2022

Abstract
The accurate measurement of tooth surface deviation is an important prerequisite for the quality monitoring of high-precision spiral bevel gears. A measurement method for tooth surface deviation of spiral bevel gears is proposed based on a one-dimensional probe, which can accurately measure and evaluate tooth flank. According to the forming principle of the spiral bevel gear tooth surface, the theoretical surface is constructed as the measurement reference flank. A series of measures and methods are adopted to ensure the accuracy and correctness of one-dimensional probe measurement. These effective methods include the construction of a precise positioning model of the gear blank and its surface, the measurement planning of reduction dimension which the gear needs to rotate once the normal angle after each point is measured, and the compensation for the increasing dimension of the one-dimensional probe. In addition, minimization of the normal deviation of the tooth flank is achieved by using the optimum matching technique of the theoretical and the actual surfaces. The deviation degree of the actual surface relative to the theoretical surface can be accurately calculated and evaluated by establishing a deviation model, which ensures the correctness of the evaluation result of the deviation. Finally, the test of tooth surface deviation is carried out on a JD45+ gear measuring center (GMC) using a one-dimensional probe and a Gleason 650GMS GMC using a three-dimensional probe. The measurement results show that the evaluation results of the one-dimensional probe are in good agreement with those of the three-dimensional probe. The proposed theory and method not only expand the measurement range of the GMC using a one-dimensional probe, but also have certain reference significance for the precision measurement of other complex surfaces.
Unbalanced fault diagnosis of rolling bearings using transfer adaptive boosting with squeeze-and-excitation attention convolutional neural network
Authors: Zhao Ke , Jia Feng , Shao Haidong 
Published: December 2022

AbstractFor practical fault diagnosis issues, normal data are always much more numerous than fault data, so this paper focuses on how to accurately classify the unbalanced datasets. Compared to individual models, the ensemble model can combine multiple models together to achieve higher identification accuracy. In this paper, a transfer adaptive boosting method (AdaBoost) with a squeeze-and-excitation attention convolutional neural network (SEACNN) is proposed to tackle the unbalanced fault diagnosis issues of rolling bearings. Firstly, an SEACNN is designed to extract representative fault features and improve identification performance. Secondly, a new AdaBoost is designed for the SEACNN to efficiently handle unbalanced fault datasets. Thirdly, transfer learning is adopted to sequentially transfer the learned knowledge of one SEACNN estimator to the next estimator, and update the weights in the process. Substantial experiments are conducted to sufficiently evaluate the effectiveness of the proposed method.

Degenerate lake equations: classical solutions and vanishing viscosity limit
Authors: Al Taki Bilal , Lacave Christophe 
Published: December 2022

Abstract
The objective of this paper is twofold. First, we show the existence of global classical solutions to the degenerate inviscid lake equations. This result is achieved after revising the elliptic regularity for a degenerate equation on the associated stream-function, and adapting the method used for construction of classical solutions to the incompressible Euler equations. Second, we show that the weak solutions of the viscous lake equations converge to classical solutions of the inviscid lake equations when the viscosity coefficient goes to zero, which constitutes an important physical validation of these models. The later result is achieved by the use of energy method as in the proofs of Kato-type theorems. This method also allows us to expose a convergence rate.

Authors: Song Ke , Kang Yuchi 
Published: December 2022

Abstract
The Fluid-structure interaction characteristics on the two drag-type horizontal axis hydraulic turbinesare investigated. The results show that the two drag-type horizontal axis hydraulic turbines are suitable for operation under low flow rate and low TSR conditions. The Tuebine 2 has a higher CP
value from TSR=0.5 to TSR=2.0, and has a lower CT
value in the whole TSR rangethan the Turbine 1. The maximum stresses are at the blade root area, and the maximum deformations are at the blade tip for both turbines. The Turbine 1 has a higher stress level and total deformation than the Turbine 2. The frequency on 1st, 2nd, 3rd, 4th and 5th order vibration modes of the Turbine 1 is higher than the Turbine 2, and the 6th one is not. The results provide a reference for the drag-type horizontal-axis hydraulic turbines.

Published: December 2022

Abstract
The distributions of charge trap energy levels in polymer insulation material have an important influence on the charge transport characteristics and breakdown field strength of the polymer insulation, which thus has attracted considerable attention. Based on the quantum chemistry calculations, the characteristics of charge traps induced by different chemical defects and additives in silicone rubber materials are investigated. The projected density of states, and frontier molecular orbital distribution of defective silicone rubber and additive molecules are analyzed. The carbonyl defect, carboxyl defect and diethyl maleate additive all introduce deep electron traps (more than 1eV) in PDMS materials. The carbonyl defect and KH550 additive introduce shallow hole traps (less than 1eV) in PDMS materials. If chemical defects have a dominant contribution to the frontier molecular orbital of polymer is the key factor of whether they can introduce charge traps.
