Published: March 2024

Background The three main causes of neonatal deaths in Indonesia according to the WHO are sepsis, prematurity, and asphyxia. A suboptimal hospital environment increases the risk of late-onset neonatal sepsis (LONS), which in turn can prolong hospital stays.
Objective To assess for possible associations of bacterial patterns in neonates with LONS, prematurity, and/or low birth weight.
Methods Medical record data of 1,706 hospitalized neonates who were treated for sepsis or other disease in the Neonatal Unit, Dr. Cipto Mangunkusumo Hospital (CMH), Jakarta in 2020 were analyzed retrospectively. A total of 262 neonates had proven LONS. We assessed for possible risk factors such as gestational age, birth weight, and cultured blood microbes.
Results Out of a total of 1,706 neonates admitted to the neonatal unit, the incidence of proven LONS was 15.4%. LONS was more prevalent (58.4%) in preterm than in full-term (41.6%) neonates. The majority (67.6%) of subjects with proven LONS were neonates with low birth weight (LBW) (<2,500 grams), and the largest percentage of them (35.1%) was in the 1,500-2,500-gram group. Gram negative bacteria emerged as the predominant pathogens of LONS patients in our hospital; the most common were Klebsiella pneumonia, Acinetobacter spp., Escherichia coli, Enterobacter spp., and Pseudomonas aeruginosa.
Conclusion The proportion of LONS among LBW and preterm neonates is significantly higher compared to normal birth weight and neonates. In our unit, LONS was mostly caused by Gram-negative bacteria. The antibiotic susceptibility of the various pathogens causing LONS in CMH should be tested and compared to the current empirical antibiotic guidelines used in CMH.

Published: March 2024

Abstract
Enterprise wide area network (WAN) is a private network that connects the computers and other devices across an organisation’s branch locations and the data centers. It forms the backbone of enterprise communication. Currently, multiprotocol label switching (MPLS) is commonly used to provide this service. As a recent alternative to MPLS, software-defined wide area networking (SDWAN) solutions are being introduced as an IP based cloud-networking service for enterprises. SD-WAN virtualizes the networking service and eases the complexity of configuring and managing the enterprise network by moving these tasks to software and a central controller. The introduction of new technologies causes concerns about their security. Also, this new solution is introduced as a replacement for MPLS, which has been considered secure and has been in use for more than 16 years. Thus, there is a need to analyze the security of SDWAN, which is the goal of this thesis.
In this thesis, we perform a security analysis of a commercial SD-WAN solution, by finding its various attack surfaces, associated vulnerabilities and design weaknesses. We choose Nuage VNS, an SD-WAN product provided by Nuage Networks, as the analysis target. As a result, many attack surfaces and security weaknesses were found and reported, especially in the Customer Premises Equipment (CPE). In particular, we found vulnerabilities in the CPE’s secure bootstrapping method and demonstrated some attacks by exploiting them. Finally, we propose mitigation steps to avoid the attacks.
The results of this thesis will help both the service provider and the SD-WAN solution vendor to know about the attack surfaces and weaknesses of SD-WAN before offering it to their customers. We also help in implementing the temporary countermeasures to mitigate the attacks. The results have been presented to the service provider and the vendor of the SDWAN product.

INTRODUCTION:
There is substantial variability in patient outcomes for gastrointestinal bleeding (GIB) across hospitals. This study aimed to identify hospital factors associated with GIB outcomes.

METHODS:
This was a retrospective cohort study of Medicare fee-for-service beneficiaries hospitalized for GIB from 2016 to 2018. These data were merged with the American Hospital Association Annual Survey data to incorporate hospital characteristics. We used generalized linear mixed-effect models to estimate the effect of hospital-level characteristics on patient outcomes after adjusting for patient risk factors including anticoagulant and antiplatelet use, recent GIB, and comorbidities. The primary outcome was 30-day mortality, and secondary outcomes included length of stay and a composite outcome of 30-day readmission or mortality.

RESULTS:
Factors associated with improved GIB 30-day mortality included large hospital size (defined as beds >400, odds ratio [OR] 0.93, 95% confidence interval [CI] 0.90–0.97), greater case volume (OR 0.97, 95% CI 0.96–0.98), increased resident and nurse staffing (OR 0.88, 95% CI 0.83–0.94), and blood donor center designation (OR 0.93, 95% CI 0.88–0.99). Patients treated at a hospital with multiple advanced capabilities, such as availability of advanced endoscopy, advanced intensive care unit (ICU) capabilities (both a medical-surgical ICU and cardiac ICU), blood donor center, and liver transplant center, had a 22% reduction in 30-day mortality risk, compared with those hospitalized in a hospital with none of these services (OR 0.78, 95% CI 0.68–0.91). However, length of stay increased with additional services.

DISCUSSION:
Patients hospitalized for GIB at hospitals with multiple advanced specialized capabilities have lower mortality but longer lengths of stay. Further research should examine the processes of care linked to these services that contribute to improved mortality in GIB.
Students got mail: Do students read semi-tailored emails and what is the impact?
Authors: Reynolds Madison , Tyler Jonathan , Wakefield James , Wight Raechel 
Published: March 2024

This paper examines the effectiveness of providing personalised email feedback via an automated email application in a large undergraduate introductory accounting course. Over 1,200 students received feedback via emails sent weekly, semi-tailored to each student based on their results in online self-test learning quizzes. We first found that students read the majority of emails distributed. Second, through tracking, using regression analysis, we found that reading emails is related to significantly higher final examination performance in some cases. However, this is moderated by factors relating to diversity in a large cohort exceeding 1,000 students. The results indicate that feedback needs to be readily actionable and aligned with assessed learning outcomes to realise significant impacts on exam performance. This study is relevant to educators who teach large and diverse cohorts and need time-efficient solutions to tailor the learning experience to each student.

Implications for practice or policy:

Undergraduate students read the majority of weekly emails distributed, indicating emails can be used as an instructor communication device.
Emails should specifically encourage activity completion aligning with learning objectives to improve grades.
Students who achieve lower grades in tertiary studies, from English-speaking backgrounds and medium to high socio-economic status, high performers at high school and younger students aged 20 or less are positively impacted. Therefore, emails should be used by instructors teaching cohorts with these characteristics.
An investigation of Persian response signals from an interactive perspective
Authors: Ghaderi Soleiman 
Published: March 2024

Abstract
Response signals (RS) have emerged as a powerful interaction tool, but they have yet to be fully understood. The current study analyzes 16 h of daily conversations using discourse-pragmatic frameworks to discuss certain aspects of the most prevalent primary and secondary Persian RSs. An RS is identified as a brief interactive response to a prior speaker’s statement, typically expressing (dis)confirmation, (un)acceptance, or backchannel (including assessment and continuer feedback). The research also differentiates and compares the functional and distributional differences and similarities between confirmation and backchannel signals. Following that, it takes a semasiological approach and discusses how the emergence, overlap, and markedness of certain functions for an item can be determined by the persistence of its original propositional meaning as well as the item’s grammaticalization and cooptation. The paper thus reviews the markedness of the backchannel function for na ‘no’ compared to this function’s development for ɂāre ‘yes’. Last but not least, cross-linguistic phonological tendencies, such as the integration of the phoneme /ɂ/ or /h/ in positive RSs and click sounds in negative ones, are supported by Persian RSs and their variants.
High thermal stability effect of vanadium on the binary CuAl base alloy for a novel CuAlV high-temperature shape memory alloy

Published: March 2024

Abstract
In this study, two high-temperature shape memory alloys (HTSMAs) of CuAlV with unprecedented chemical compositions were fabricated using the arc melting technique, followed by traditional ice-brine water quenching after the melting process. To characterize the shape memory properties and structure of the alloys, a series of tests including differential calorimetry (DSC and DTA), EDS, optical microscopy, and XRD were conducted. The DSC tests, performed at different heating and cooling rates, demonstrated highly stable reversible martensitic phase transformation peaks at high temperatures, which were also confirmed by the results of DTA tests. Microstructural XRD and optical microscopy tests were conducted at room temperature, revealing the martensitic structure of the alloys in both cases. Based on all the results, the effects of different minor amounts of vanadium additives directly on the CuAlV alloy were discussed.

Abstract
Understanding the ultrafast excitation, detection, transportation, and manipulation of nanoscale spin dynamics in the terahertz (THz) frequency range is critical to developing spintronic THz optoelectronic nanodevices. However, the diffraction limitation of the sub-millimeter waves – THz wavelengths – has impaired experimental investigation of spintronic THz nano-emission. Here, we present an approach to studying laser THz emission nanoscopy from W|CoFeB|Pt metasurfaces with ∼60-nm lateral spatial resolution. When comparing with statistic near-field THz time-domain spectroscopy with and without the heterostructures on fused silica substrates, we find that polarization- and phase-sensitive THz emission nanoscopy is more sensitive than the statistic THz scattering intensity nanoscopy. Our approach opens explorations of nanoscale ultrafast THz spintronic dynamics in optically excited metasurfaces.
Das unwahrscheinliche Überleben des Bankhauses Gebr. Bethmann, 1919 bis 1948
Authors: Schneider-Braunberger Andrea H. 
Published: March 2024

Abstract
The long-term orientation of family businesses is particularly evident in crises. The example of the Gebrüder Bethmann bank in Frankfurt am Main, whose state of crisis began during the First World War and continued almost uninterrupted until the 50s, shows how far business families are prepared to go. The essay traces the developments and shows the measures taken by the bank and the banking family to counter the crises and their consequences. It shows that Baron Moritz von Bethmann made himself an instrument of the National Socialists and implemented their policies in associations, societies and companies – particularly with regard to the ousting of Jews from German economic and social life. However, his political role did not help him to run his business more successfully or to preserve his family property. In order to at least preserve Bankhaus Gebr. Bethmann – already almost 200 years old at the time – for the family, he sacrificed almost all of the real estate and land owned by the von Bethmann family. Despite this high price, the bank remained in the family for only one more generation.
Auswirkung von Strukturadaptionen auf die Veränderungsfähigkeit von Fabriken

Published: March 2024

Abstract
Manufacturing companies operate in an environment characterized by turbulences and volatility, resulting in the need for permanent adaptation of existing factory structures. An important characteristic in this context is the factory‘s ability to change (changeability), which is defined as the ability to adapt structures rapidly and with acceptable effort. The changeability is a dynamic variable that can change as a result of structural adaptations and thus affect the degree of planning freedom in future periods. This article presents a planning approach that can be used to identify and evaluate the effects of structural adaptations on a factory‘s changeability.

Abstract
In recent decades, the increasing product variant diversity has led to further flexibilization of assembly organization. The challenge is to maintain productivity with low volumes per product variant in a flow assembly line designed for high volumes. The combination of different assembly organization forms creating a hybrid, flow-oriented form represents a solution that can provide the high performance of an assembly line combined with the necessary flexibility to cover the diversity of product variants. This paper proposes a novel method for companies to investigate the suitability of their assembly to realize a hybrid assembly organization and provides the steps required for its implementation.

Abstract
Das Mikrofräsen mit Hartmetallwerkzeugen ist ein weit verbreitetes Verfahren zur Herstellung von Mikrostrukturen, während technische Keramiken als Werkzeugsubstrat bisher nicht zum Einsatz kommen. In vorangegangenen Untersuchungen hat sich beim Mikrofräsen von PMMA (Polymethylmethacrylat) ein deutlicher Verschleißvorteil gegenüber Hartmetallwerkzeugen gezeigt. In dieser Studie war es das Ziel, den Einfluss der Mikrofräsparameter (Zahnvorschub, Spindeldrehzahl) auf die Prozessergebnisse beim Mikrofräsen von PMMA zu ermitteln. Dabei wurde mit einem höheren Zahnvorschub der Werkzeugverschleiß um 50 Prozent reduziert, und es wurde gezeigt, dass die Oberflächenrauheit ausschließlich von der Prozesskinematik abhängt.

Links Between Body Satisfaction and Relationship Satisfaction in a Sample of Young Adult Women in Lithuania
Authors: Legkauskas Visvaldas , Ališauskaitė Elzė 
Published: March 2024

The aim of the present study was to examine links between young adult women satisfaction with their bodies and romantic relationships. The study involved 162 young adult women aged 20–35. One hundred and nineteen women indicated that they currently had a partner and the remaining 43 participants indicated that they were single.
Body satisfaction was measured using the Multidimensional Body-Self Relations Questionnaire (MBSRQ, Cash, 2000). Relationship satisfaction was assessed using the Couple’s Satisfaction Scale (Čepukienė, 2019).
Results of the study indicated that adult women who had a romantic partner valued their appearance as more physically attractive and were more satisfied with their appearance than young adult women without a romantic partner. Those with a partner were more satisfied with individual body parts than women without a romantic partner. On the other hand, those in a relationship were more concerned about their body weight than single women. Satisfaction with a body and satisfaction with a romantic relationship were partly related. A more favorable assessment of one’s appearance and satisfaction in individual parts of one’s body was associated with satisfaction with emotion- and behavior-oriented interactions, as well as overall satisfaction with romantic relationships.
Rate of Urinary Tract Infections, Bacteremia, and Meningitis in Preterm and Term Infants
Authors: Graf Thomas , Malay Sindhoosha , Frank Erin 
Published: March 2024

BACKGROUND AND OBJECTIVES
There are very limited data on the rate of urinary tract infections (UTI), bacteremia, and meningitis in preterm infants with fever. Many of the studies on the incidence of these infections excluded preterm infants. This study compared the rate of these infections in preterm infants born at 32–36 weeks to term infants born at 37–42 weeks.

METHODS
A multicenter observational cohort study was conducted to evaluate rates of UTI, bacteremia, and meningitis in term and preterm infants 8–60 days of age with a diagnosis of fever from 2016 through 2022 using encounter data from children’s hospitals in the Pediatric Health Information System.

RESULTS
There were 19 507 total febrile infants identified, of which 2162 were preterm and 17 345 were term. Preterm infants had a lower rate of UTI than term infants (1.8% confidence interval [CI] [1.3–2.5] vs 3.0% CI [2.7–3.2], P = .001). Preterm and term infants did not have statistically different rates of bacteremia (1.5% CI [1.3–1.7] vs 1.2% CI [0.8–1.8], P = .44) or meningitis (0.16% CI [0.1–0.2] vs 0.05% CI [0–0.2], P = .36).

CONCLUSIONS
There was no difference in the rate of bacteremia or meningitis between term and preterm infants in a large multicenter cohort of febrile infants. Preterm infants had a lower rate of UTI than term infants. This is the first multicenter study to compare UTI, bacteremia, and meningitis between term and preterm febrile infants.
