Abstract
This paper reports on the design of the GUI component of the PV1000, a fully-functional, cost-efficient pandemic ventilator developed during the COVID-19 pandemic. Our main objective in designing the user interface was to expose the rich features of the ventilator, which are on-par with many commercial medical devices, through an interface that is simple to use even by medical staff with little prior experience with ventilators. We present an agile development process which is intended to address the fast changing and potentially unclear requirements of a pandemic. This is to address the specific situation where domain experts as well as specific hardware have shortages, resulting in recurring changes in requirements. This occurs in conjunction with the collaboration of developers, not all of whom are familiar with the development of medical devices. Despite the pandemic situation, we have made a deliberate decision to use existing software engineering tools such as continuous integration. Additionally, we are employing a multi-platform development framework in order to utilise the resulting advantages, for example, if there are changes in requirements. We present and discuss the system, hardware and software architecture of the components that allow users to interact with the device. The focus here is on the dynamic generation of parts of the software architecture, which enables rapid adaptation to changing conditions on the part of the software. The user interface is evaluated through a user survey, where the majority of participants describe the interface as clear and intuitive. The entire ventilator was evaluated in one animal trial and fortunately never had to be used on humans. The next step is to convert the setup into an open source project that can be used as a research platform for ventilators.
Muscle fatigue detection based on sEMG signal using autocorrelation function and neural networks

Published: May 2024

Abstract
Feature extraction from an recorded surface electromyography (sEMG) signal plays an important role in identifying and quantifying the characteristics of muscle activities. These features can be used for various applications like muscle function assessment, muscle fatigue detection, etc. Common features extracted from sEMG signal are time-domain or frequency-domain features. However, features which are sensitive to uncertainties in the signal like noise, movement artifacts, and outliers should be avoided. Autocorrelation function (ACF), which is a measure of similarity between a signal and its time delayed version, is considered in this work as a feature to overcome the impact of noise, artifacts, and outliers. An artificial neural network (ANN) is developed to differentiate between fatigue and non-fatigue conditions using the calculated ACF from sEMG segments. The performance of an ANN model that can be adapted by means of various regularization methods was investigated. The proposed ANN model achieved an accuracy of about 97.62 %, a precision of about 95.50 % and a sensitivity of about 100 % in the classification of fatigue and non-fatigue sEMG segments, outperforming k-means and linear support vector machine approaches that served as references.

Published: May 2024

Abstract
In this article, we first study the inverse source problem for parabolic with memory term. We show that our problem is ill-posed in the sense of Hadamard. Then, we construct the convergence result when the parameter tends to zero. We also investigate the regularized solution using the Fourier truncation method. The error estimate between the regularized solution and the exact solution is obtained.
Playback interviews as a method for research on language ideologies: Citationality, reflexivity, and rapport in interdiscursive encounters
Authors: Grosser Florian 
Published: May 2024

Abstract
This contribution deals with the use of playback interviews in interactional sociolinguistics, a method wherein participants review audio or video recordings of their conversations and provide retrospective commentary. I first outline a brief history of the development of the playback method and how it was incorporated into the interactional sociolinguistic research agenda. As theoretical frameworks for playback interviews and their application to research on language ideologies remain underexplored, this article introduces three concepts from linguistic anthropology—citationality, reflexivity, and interdiscursivity—to theorize playback interviews from a semiotic perspective. Departing from these theories, playback interviews are contextualized within broader social dynamics, including participation frames, power, and rapport that are inherent in the interviewing process. Drawing on source recordings from interactions between L1 and European L2 users of Japanese in Tokyo, and playback sessions with the L2 users, I illustrate how playback interviews contribute to language-ideological inquiries, for example, perceptions of style and code-switching. The analysis showcases the method’s potential to unveil participants’ metapragmatic awareness and explore the intersection of linguistic structure, practice, and ideology. Playback interviews are positioned as a valuable tool for investigating language ideologies, offering new methodological perspectives through retrospection and reflection on communication.
Epilogue: The traces and tracings of language ideologies
Authors: Spitzmüller Jürgen 
Published: May 2024

Abstract
This epilogue highlights and bundles some major points and perspectives that have been identified in the papers of this special issue and locates them in the wide field of language ideology research. By doing that, the epilogue sets out to sketch major trends in the past, present and (anticipated) future of the research field, thereby showing (sometimes hidden) traditions, achievements and challenges of language ideology research (and related fields). Particularly, the (re-)emerging interest in affectual dimensions, social positioning, institutional ideology brokerage, social inequality, and power, which are at the center of a number of papers each, are being highlighted and discussed. In a historical contextualization, the epilogue furthermore shows how these topics and interests can be traced back in the fields history and even further to long-standing engagements with language ideologies avant la lettre.

Abstract

Objectives
The aim of this study was to record parents’ knowledge and attitudes towards bullying experienced by their children and to explore the strategies they choose to manage bullying incidents.

Methods
A cross-sectional study was conducted. The study population consisted of parents of children who have experienced bullying in a primary or secondary school classroom. The “Parents’ Strategies to Cope with Bullying” questionnaire was used to collect data. Regarding parents’ coping with bullying, the strategy “Support and advice to the child” scored the highest and the strategy “Social support and information” the next highest.

Results
Of the parents, 44.3 % had received some information/education regarding the phenomenon of bullying with the most important source of information being reading. According to the results of multivariate linear regression, mothers more often applied the strategy “social support and information” (Coefficient b=0.9, 95 % CI for b=0.7 to 1.1, p<0.001) and parents with lower educational level more often applied the strategy “avoidance” (Coefficient b=−0.5, 95 % CI for b=−0.8 to −0.2, p=0.004).

Conclusions
School bullying remains a major worldwide phenomenon over time. Although parents choose to support their children, they do not receive information and training on how to manage bullying from a formal institution, making the need for such programs imperative.
Violations of the basic Japanese referential system in reintroductions
Authors: Muranaka-Vuletich Hiromi 
Published: May 2024

AbstractReferential systems are language specific, and the Japanese referential system is achieved by using grammatical particles (waandga) as well as ellipsis. While there are basic patterns, violations of these patterns commonly occur. This study examined the reasons why violations could occur by focusing on reintroductions. The data were collected from ten oral narratives and five written narratives. The results demonstrated that grammatical constraints and additional functions constituted the two main reasons why the most expected referential markings were not used. Other observed factors included the centeredness of the character in the story and the different types of referential markings. It was also found that referential markers were highly related to predicates that could predict which particle would predominantly be used. However, predicates themselves were not the only primary driver of particle selection. Instead, other components of the sentence outside the predicates may have contributed to the selection of referential marking.

Published: May 2024

Abstract
Der Umfang von Qualitätsprüfungen von gefrästen Großbauteilen in der Luftfahrtindustrie stellt einen großen Anteil an nicht-wertschöpfenden Tätigkeiten dar und verursacht hohe Zeit- und Kostenaufwände. Ein Ansatz zur Reduzierung derartiger Aufwände besteht in der Durchführung virtueller Qualitätsprüfungen durch Auswertung relevanter Datenströme. Eine Herausforderung besteht in der Gewährleistung einer ausreichenden Übertragbarkeit der Prognosemodelle bei sich verändernden Fertigungsbedingungen. Zur Untersuchung der Resilienz virtueller Qualitätsprüfungen wurde daher ein Ansatz zum kontinuierlichen Lernen datenbasierter Prognosemodelle entwickelt. Die Ergebnisse haben gezeigt, dass das Qualitätsniveau bei etwa 91 Prozent der unbekannten Daten richtig klassifiziert werden konnten.

Published: May 2024

Abstract
Für die Fertigung von Prototypenbauteilen sind flexible Anlagen erforderlich, die stabile Prozesse für sich ständig ändernde Bauteile gewährleisten und die Anforderungen an die Technische Sauberkeit erfüllen. Die Reinigung von Prototypen-Zylinderkurbelgehäusen im BMW Motorrad Werk Berlin entspricht nicht den Qualitätsvorschriften. Struktur- und Ausrichtungsmängel sowie Transportgestelle, Handschuhe und Kühlschmierstoff begünstigen Partikelverschleppung zwischen Fertigungsschritten. Feldversuche zeigen, dass Anpassungen von Prozessparametern zu einer deutlichen Reduktion von Partikelmengen führen. Lösungsansätze umfassen einen verbesserten Waschprozess mit angepasstem Ablauf sowie konstruktive Änderungen in der Bauteilausrichtung.

Published: May 2024

Abstract
Besondere Merkmale sind ein wichtiges Element, um die Funktionssicherheit von Produkten sicherzustellen. Bei Nichterfüllung drohen haftungsrechtliche Konsequenzen. Gleichzeitig verursachen sie hohe Aufwände für Prüfung und Dokumentation. Der VDA-Band „Besondere Merkmale“ gibt eine Systematik zur Reduzierung vor. Darin nicht berücksichtigt ist der Anwendungskontext. Wie damit sicherheitsrelevante Besondere Merkmale reduziert und Anforderungen für Produktion und Prüfung abgeleitet werden können, wird im vorliegenden Beitrag erläutert.

Authors: Cohen-Silver Justine , Cost Katherine , Navarro Jose , Maguire Jonathon L. 
Published: May 2024

OBJECTIVESThe Pediatric psychoSocial Risk Index (PSRI) is psychosocial risk screening instrument for health practitioners. The objective of this study was to confirm validity evidence of a truncated version of PSRI.METHODSPSRI was completed initially by 100 parents of children aged 0 to 18 years admitted to a tertiary hospital; 50 parents repeated the PSRI 3 days later. Analysis includes principal component analysis (PCA) to include the least number of items that explain the most variance in a shortened version of PSRI as well as confirming test-retest reliability and internal consistency of the shortened instrument.RESULTSPSRI originally had 86 items, 85 close-ended items were analyzed. Three items were excluded because of missing test-retest data. Item reduction resulted in truncation of 16 items; 66 items remained. A Kaiser-Mayer-Orkin test of sampling adequacy resulted in reduction of 14 items; 52 items remained. Initial PCA led to reduction of 26 items. The PCA was rerun on remaining items, resulting in reduction of 6 further items; 18 items remained. Two items with &gt;10% missingness were removed leaving 16 items in the final PSRI. Test-retest reliability was 0.98 and mean within-person across-item reliability was 0.95. Cronbach α was 0.9. Remaining items represented 9 social risk themes: food insecurity, medical complexity, home environment, behavioral issues, financial insecurity, parenting confidence, parental mental health, social support, and unmet medical needs.CONCLUSIONSPSRI was reduced from 86 to 16 items with high internal consistency and reliability. PSRI demonstrates adequate validity supporting practitioners to screen families about their psychosocial risk.
The association of Dark Triad personality traits with infidelity: Evidence from the Greek-cultural context
Authors: Apostolou Menelaos 
Published: May 2024

AbstractThe Dark Triad is an important aspect of human personality, and there is evidence that it associated with infidelity. The current research aimed to examine the association between Narcissism, Psychopathy, and Machiavellianism traits and different aspects of infidelity in the Greek cultural context. In particular, using a sample of 509 Greek-speaking participants [57.5% women, mean age 36.5 (SD = 11.7), 42.5% men, mean age 40.1 (SD = 13.1)], we found that higher scores in Psychopathy were associated with higher incidence of infidelity and willingness to be unfaithful to one's partner. Moreover, men and women who scored higher in Psychopathy were more likely to be detected by their partners when unfaithful. Men who scored high in Psychopathy were also more suspicious of their partners for being unfaithful than men who scored low. However, the scores in the Dark Triad traits did not predict the probability to detect a partner's infidelity neither for men nor for women. Overall, in the Greek cultural context, the Dark Triad traits were associated with certain aspects of infidelity.

El principio de la participación en el sistema de seguridad social venezolano para impulsar la gestión del conocimiento
Authors: García Palma Xiomara Coromoto 
Published: May 2024

La participación como principio operativo de la seguridad social permite la instrumentación de la política social en los diferentes subsistemas de protección social. Hasta ahora, en Venezuela, estos sistemas se han ejecutado bajo un modelo burocrático, jerárquico y técnico, en el que los procedimientos no permiten la participación de la población en las políticas de la seguridad social ni el control que tienen sobre estas. Su involucramiento en estos últimos 20 años se ha limitado a recibir subsidios, mientras que el Estado ha ido creando sistemas paralelos de protección, denominados ‘misiones’ o ‘grandes misiones’, que debilitan los sistemas como el de salud o vivienda, además del empleo y el salario. Cuando la población ejerce la participación, se gestiona un sistema de seguridad social eficaz, incluyente, con carácter equitativo y justo para la sociedad. Dicho esto, es posible desplazar la burocratización hacia un modelo democrático, descentralizado y de gobernanza, que gestione el conocimiento desde la construcción colectiva y permita la apropiación social de los principios doctrinarios de la seguridad social como cultura y modo de vida en sociedad.
Morphology Behavior of Polysulfone Membranes Made from Sustainable Solvents
Authors: Kluge Steven , Hartenauer Karla , Tutuş Murat 
Published: May 2024

In a previous study we could show a change of membrane morphology and gas separation performance by varying the recipe of a casting solution based on polysulfone in a determined solvent system. Although all results were very reproducible, all used solvents were harmful and not sustainable. In this study therefore, the solvents tetrahydrofuran (THF) and N,N-dimethylacetamide (DMAc) are replaced by the more sustainable solvents 2-methyl-tetrahydrofuran (2M-THF), N-butyl pyrrolidinone (NBP) and cyclopentyl methyl ether (CPME). The gas permeation performance and for the first time morphology of the membranes before and after solvent replacement were determined and compared by single gas permeation measurements and SEM microscopy. It is shown, that THF can be replaced by 2M-THF and NBP without decreasing the gas permeation performance. With CPME replacing THF no membranes were formed. Best gas permeation results showed systems with 2M-THF as THF alternative. Permeances for the tested gases oxygen (O2), nitrogen (N2), carbon dioxide (CO2) and methane (CH4) were 2.66·10-4, 3.89·10-5, 1.53·10-3 and 4.52·10-5 mL(STP)/cm²·min·bar, respectively. permselectivities of those membranes for the gas pairs O2/N2, CO2/N2 and CO2/CH4 were 6.7, 38.3 and 34.0, respectively. When additionally replacing DMAc in the solvent system no or only porous membranes were obtained, even if the precipitation procedure was adjusted. These findings indicate that a complete replacement of the solvent system without affecting the membrane morphology or gas permeation performance is not possible. By varying the temperature of the precipitation bath an easy adjustment to mechanically stable PSU membranes is possible, if just THF was replaced by 2M-THF.
Exhibition of <em>Corallopyronin A </em>an Antibiotic from Different Soil Environments in Egypt
Authors: Kassab Mohammed Mahmoud Shawky 
Published: May 2024

Background:
Across the world, antibiotic resistance is a critical challenge. To address such a problem, it has to be done to investigate new antibiotic sources.
Aim of the study:
Study of the antibacterial activity of Corallopyronin A in preclinical animal testing and randomized human clinical trials stages 1/2, as well as investigating the purification of Corallopyronin A from different soil conditions in Egypt.
Type of the study:
Screening experimental study.
Methodology:
Egypt&#039;s various soil conditions were tested to develop bacterial isolates that produced the antibiotic compound Corallopyronin A. Reversed phase HPLC was used to purify Myxopyronin A. The broth microdilution method and the paper disc diffusion assay determined the test antibiotic&#039;s minimum inhibitory concentration( MIC) and in vitro antibacterial activity. Moreover, in vivo antibacterial spectrum, adverse medication responses, and pharmacokinetics were found in phases 1/2 of randomized clinical studies involving humans and animal models.

Results:
Corallopyronin A was generated from the culture supernatant of the soil bacterial isolate Corallococcus coralloides M2, cultivated on a Casein yeast peptone( CYP) plate. The test antibiotic prevented the growth of several Gram-ve bacteria, including Escherichia coli, at MICs higher than 100 mcg/ ml; while blocking the development of many Gram +ve bacteria, with MICs ranging from 3 to 15 mcg/ ml. However, eukaryotic cells—such as those found in fungi and humans—were unaffected. A bactericidal consequence of the test antibiotic was detected in the inhibition of prokaryotic DNA-dependent RNA polymerase( RNLP). Conclusion:
The synthesis of the bactericidal antibiotic Corallopyronin A from Corallococcus coralloides M2 isolated from different soil settings in Egypt intrigued the current investigation.
