Background: Maternal respiratory syncytial virus (RSV) vaccines that are likely to be implementable in low- and middle-income countries (LMICs) are in final stages of clinical trials. Data on the number of women presenting for antenatal care (ANC) per day and proportion attending within the proposed gestational window for vaccine delivery, is a prerequisite to guide development of vaccine vial size and inform vaccine uptake in this setting. Methods: We undertook administrative review and abstraction of ANC attendance records from 2019 registers of 24 selected health facilities, stratified by the level of care, from Kilifi, Siaya and Nairobi counties in Kenya. Additional data were obtained from Mother and Child Health (MCH) booklets of women in each of the Health and Demographic Surveillance System (HDSS) areas of Kilifi, Nairobi and Siaya. Data analysis involved descriptive summaries of the number (mean, median) and proportion of women attending ANC within the gestational window period of 28-32 weeks and 24-36 weeks. Results: A total of 62,153 ANC records were abstracted, 33,872 from Kilifi, 19,438 from Siaya and 8,943 from Nairobi Counties. The median (Interquartile range, IQR) number of women attending ANC per day at a gestational age window of 28-32 and 24-36 weeks, respectively, were: 4 (2-6) and 7 (4-12) in dispensaries, 5 (2-9) and 10 (4-19) in health centres and 6 (4-11) and 16 (10-26) in county referral hospitals. In the HDSS areas of Kilifi, Siaya and Nairobi, pregnant women attending at least one ANC visit, within a window of 28-32 weeks, were: 77% (360/470), 75% (590/791) and 67% (547/821), respectively. Conclusions: About 70% of pregnant women across three distinct geographical regions in Kenya, attend ANC within 28-32 weeks of gestation. A multidose vial size with about five doses per vial, approximates daily ANC attendance and would not incur possible wastage in similar settings.

Cel pracyZaburzenia Lękowe Specyficzne dla Ciąży występują ze znaczną częstością i związane są z powikłaniami u matek i ich dzieci. Jest to schorzenie odrębne od innych zaburzeń lękowych, stąd stosowanie standardowych testów przesiewowych nie jest wystarczające. Brak jest polskiej wersji testu przesiewowego specyficznego dla tego zaburzenia. Naszym celem jest stworzenie polskiej adaptacji Pregnancy-Related Anxiety Questionnaire Revised 2 (PRAQ-R2), który jest szeroko stosowany za granicą.MetodaPRAQ-R2 został przetłumaczony na język polski przez niezależne osoby, mówiące biegle po polsku i angielsku. Czterdzieści osiem ciężarnych wypełniło ankietę zawierającą polską wersję PRAQ-R2, Hospital Anxiety and Depression Scale Modified (HADS-M) oraz krótki Kwestionariusz Socjodemograficzny. Po tygodniu uczestniczki badania zostały poproszone o ponowne wypełnienie kwestionariusza PRAQ-R2. Do oceny właściwości psychometrycznych wykorzystano statystyki parametryczne.WynikiNasze badanie wykazało dobrą korelację test-retest na poziomie 0,70. Współczynnik alfa Cronbacha wynosił 0,847 w t1 i 0,895 w t2. Wykazano umiarkowaną korelację pomiędzy PRAQ-R2 w obu punktach czasowych a skalą HADS-M i jej podskalami.WnioskiBadanie adaptacyjne PRAQ-R2 wykazało jego satysfakcjonującą trafność i rzetelność. Umiarkowana korelacja z HADS-M dowodzi, że lęk związany z ciążą jest zaburzeniem odrębnym od lęku uogólnionego i zaburzeń depresyjnych. Biorąc pod uwagę dużą częstotliwość i poważne powikłania PrA, uważamy, że PRAQ-R2 powinien być rutynowo stosowany wśród lekarzy pracujących z pacjentkami w ciąży.
Supermodularity in Two-Stage Distributionally Robust Optimization
Authors: Long Daniel Zhuoyu , Qi Jin , Zhang Aiqi 
Published: April 2023

In this paper, we solve a class of two-stage distributionally robust optimization problems that have the property of supermodularity. We exploit the explicit worst case expectation of supermodular functions and derive the worst case distribution for the robust counterpart. This enables us to develop an efficient method to obtain an exact optimal solution to these two-stage problems. Further, we provide a necessary and sufficient condition for checking whether any given two-stage optimization problem has the supermodularity property. We also investigate the optimality of the segregated affine decision rules when problems have the property of supermodularity. We apply this framework to several classic problems, including the multi-item newsvendor problem, the facility location problem, the lot-sizing problem on a network, the appointment-scheduling problem, and the assemble-to-order problem. Whereas these problems are typically computationally challenging, they can be solved efficiently under our assumptions. Finally, numerical examples are conducted to illustrate the effectiveness of our approach. This paper was accepted by Chung Piaw Teo, optimization.

Optical fiber distributed acoustic sensing (DAS) based on phase-sensitive optical time domain reflectometry (φ-OTDR) is in great demand in many long-distance application fields, such as railway and pipeline safety monitoring. However, the DAS measurement distance is limited by the transmission loss of optical fiber and ultralow backscattering power. In this paper, a DAS system based on multispan relay amplification is proposed, where the bidirectional erbium-doped fiber amplifier (EDFA) is designed as a relay module to amplify both the probe light and the backscattering light. In the theoretical noise model, the parameters of our system are carefully analyzed and optimized for a longer sensing distance, including the extinction ratio (ER), span number, span length, and gain of erbium-doped fiber amplifiers. The numerical simulation shows that a bidirectional EDFA relay DAS system can detect signals over 2500 km, as long as the span number is set to be more than 100. To verify the effectiveness of the scheme, a six-span coherent-detection-based DAS system with an optimal design was established, where the cascaded acoustic-optic modulators (AOMs) were used for a high ER of 104 dB. The results demonstrate that the signal at the far end of 300.2 km can be detected and recovered, achieving a high signal-to-noise ratio of 59.6 dB and a high strain resolution of 51.8pε/Hz at 50 Hz with a 20 m spatial resolution. This is, to the best of our knowledge, a superior DAS sensing distance with such a high strain resolution.
Identifizierung von Wertpotenzial für digitale Services von B2B-Fertigungsunternehmen am Beispiel eines Küchengeräteherstellers

Published: April 2023

ZusammenfassungTraditionelle Business-to-Business-Fertigungsunternehmen sehen sich einem wachsenden Bedarf an digitalen Services konfrontiert, die ihre physischen Produkte ergänzen. Da die meisten digitalen Services große Datenmengen generieren, bieten sie nicht nur wertvolles Potenzial für Kunden zur Unterstützung bei der Nutzung der digitalen Services, sondern auch für den Anbieter, um die Bedürfnisse und das Verhalten ihrer Kunden besser zu verstehen. Da sich die Wertschöpfungsmechanismen digitaler Services grundlegend von denen physischer Produkte unterscheiden, sind die Preisgestaltung und die Entwicklung nachhaltiger Geschäftsmodelle eine Herausforderung für produzierende Unternehmen. Es bedarf im Gegensatz zu einem kostenbasierten Preisansatz einer wertorientierten Preisgestaltung, wozu anfangs das Wertpotenzial eines digitalen Service erfasst werden muss. Anhand des Falls des Industrieküchengeräteherstellers Kitchenwise stellen wir einen methodischen Ansatz vor, wie Unternehmen digitale Serviceangebote identifizieren können, die das physische Produktportfolio ergänzen und dadurch von einer wertorientierten Preisgestaltung profitieren. So zeigen wir, wie Kitchenwise durch die Einbindung interner und externer Stakeholder eine angemessene und akzeptierte Preisspanne für seine digitalen Services definieren konnte.

ZusammenfassungDas Innovationsmanagement wird für Unternehmen immer bedeutsamer und insbesondere die frühe Phase des Innovationsprozesses, welche aber aufgrund des volatilen Umfeld einige Herausforderungen besitzt. Der folgende gestalterische Forschungsbeitrag versucht diese Probleme aufzugreifen und mittels eines situativen Theorieansatzes zu lösen. Dafür wurde durch den Aspekt von Gamification eine neue Methode auf der Grundlage von Design Thinking systematisch und wissenschaftlich konstruiert. In einer Einzelfallstudie aus der Automobilbranche konnten durch drei verschiedene Durchläufe die neue Methode im Feld angewendet und mit den teilnehmenden Personen evaluiert werden. Die Ergebnisse zeigen einerseits auf, dass die neue Methode für die Entwicklung von Ideen genutzt werden kann und einige identifizierte Gestaltungsprobleme gelöst werden konnten. Andererseits, besitzt die Methode aber weiteren Forschungsbedarf, um die Qualität der frühen Phase des Innovationsprozesses noch weiter zu verbessern.

Introduction
Acute febrile illnesses (AFI) are a frequent chief complaint in outpatients. Because the capacity to investigate the causative pathogen of AFIs is limited in low- and middle-income countries, patient management may be suboptimal. Understanding the distribution of causes of AFI can improve patient outcomes. This study aims to describe the most common etiologies diagnosed over a 16-years period in a national reference center for tropical diseases in a large urban center in Rio de Janeiro, Brazil.

Methods
From August 2004-December 2019, 3591 patients > 12 years old, with AFI and/or rash were eligible. Complementary exams for etiological investigation were requested using syndromic classification as a decision guide. Results. Among the 3591 patients included, endemic arboviruses such as chikungunya (21%), dengue (15%) and zika (6%) were the most common laboratory-confirmed diagnosis, together with travel-related malaria (11%). Clinical presumptive diagnosis lacked sensitivity for emerging diseases such as zika (31%). Rickettsia disease and leptospirosis were rarely investigated and an infrequent finding when based purely on clinical features. Respiratory symptoms increased the odds for the diagnostic remaining inconclusive.

Conclusions
Numerous patients did not have a conclusive etiologic diagnosis. Since syndromic classification used for standardization of etiological investigation and presumptive clinical diagnosis had moderate accuracy, it is necessary to incorporate new diagnostic technologies to improve diagnostic accuracy and surveillance capacity.

The purpose of the study is to identify the design aspects of working environment based on the experience of people with disability. The first floor of Komisi Nasional Disabilitas (KND) workspace which used by National Commission for Disabilities as its secretariat, will be the priority case of this study. The study examine how to implement the inclusive design concept in the workplace focus on realizing equal opportunities in the implementation of Respect, Protection and Fulfillment of the Rights of Persons with Disabilities. The research use qualitative approach, include the use of methods such as in-depth interviews, participant observation, architectural and interior elements’ measurement based on Universal Design and Deaf Space principles. Quantitative approach is also applied by using questioners’ assessment for measuring values of environment by way of comparison with the regulations of Universal Design and Deaf Space guidelines. The results shows that personal experience of people with disability plays important role to evaluate their environment. The meaning of inclusive and accessible environment can be vary based on the participants’ interpretation. Yet during the participant observation, the study reveals that the building and interior spaces of KND have not been designed to meet the principles of universal design and deaf space. The participants mostly have done some physical adjustment and spatial/furniture arrangements to meet their personal conditions, needs, and preference to carry out their daily activities independently. In conclusion, this research proposes design parameters from the perspective of the participants elaborated with the principles Universal design and Deaf Space in effort to increase inclusivity for all users.
Two Endovascular Stent Graft Repairs Needed for an Extrathoracic Aortic Graft: Distant Complications After an Original Open Repair for a Gunshot Wound to the Chest
Authors: Kiely Kate , Arko Frank 
Published: April 2023

Abstract
Although the management of traumatic injuries to the thoracic aorta has shifted toward endovascular management, the historical standard of care is open reconstruction. Choosing to reoperate when faced with a complication from a prior open repair can be challenging; endovascular management can be a reasonable option in this situation. This report describes a 54-year-old man with a remote history of open surgery for a traumatic injury to the descending thoracic aorta who underwent endovascular aortic stent graft placement for coverage of extrathoracic graft extension with pseudoaneurysm formation and distal embolization. He returned a year later with a type IIIb endoleak with rupture into the posterolateral chest wall. A sec ond endovascular approach was used to successfully reline the graft and exclude the rupture.

Abstract

Objectives
To develop an isotope dilution-liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based candidate reference measurement procedure (RMP) for levetiracetam quantification in human serum and plasma.

Methods
Quantitative nuclear magnetic resonance spectroscopy (qNMR) was used to characterize the RMP material to ensure traceability to SI units. To quantify levetiracetam, an LC-MS/MS method was optimized using a C8 column for chromatographic separation following protein-precipitation-based sample preparation. Spiked matrix samples of serum and plasma were used to test selectivity and specificity. Matrix effects were determined by performing a post-column infusion experiment and comparing standard line slopes. Precision and accuracy were evaluated over 5 days. Measurement uncertainty was evaluated according to the Guide to the Expression of Uncertainty in Measurement (GUM).

Results
The RMP was proven to be highly selective and specific with no evidence of a matrix effect, allowing for quantification of levetiracetam within the range of 1.53–90.0 μg/mL. Intermediate precision was <2.2% and repeatability was 1.1–1.7% across all concentrations. The relative mean bias ranged from −2.5% to −0.3% across all levels and matrices within the measuring range. Diluted samples were found with a mean bias ranging from −0.1 to 2.9%. The predefined acceptance criterion for measurement uncertainty was met and determined for individual measurements independently of the concentration level and sample type to be ≤4.0% (k=2).

Conclusions
We present a novel LC-MS/MS)-based candidate RMP for levetiracetam in human serum and plasma. Its expanded measurement uncertainty of ≤4.0% meets the clinical needs in levetiracetam monitoring. Utilizing qNMR to characterize levetiracetam reference materials allowed metrological traceability to SI units.

Published: April 2023

Abstract
The problem of identification of unknown epidemiological parameters (contagiosity, the initial number of infected individuals, probability of being tested) of an agent-based model of COVID-19 spread in Novosibirsk region is solved and analyzed.
The first stage of modeling involves data analysis based on the machine learning approach that allows one to determine correlated datasets of performed PCR tests and number of daily diagnoses and detect some features (seasonality, stationarity, data correlation) to be used for COVID-19 spread modeling.
At the second stage, the unknown model parameters that depend on the date of introducing of containment measures are calibrated with the usage of additional measurements such as the number of daily diagnosed and tested people using PCR, their daily mortality rate and other statistical information about the disease.
The calibration is based on minimization of the misfit function for daily diagnosed data.
The OPTUNA optimization framework with tree-structured Parzen estimator and covariance matrix adaptation evolution strategy is used to minimize the misfit function.
Due to ill-posedness of identification problem, the identifiability analysis is carried out to construct the regularization algorithm.
At the third stage, the identified parameters of COVID-19 for Novosibirsk region and different scenarios of COVID-19 spread are analyzed in relation to introduced quarantine measures.
This kind of modeling can be used to select effective anti-pandemic programs.

Authors: Ramana Reddy D. V. , Balaram Padal K. T. , Gunda Jagadish Babu 
Published: April 2023

Abstract
In this work, an application of two noded beam finite element methodology, which is demonstrated in the previous research work for vibration analysis of beam with a flexible joint problem, has been further extended here to investigate the buckling behaviour of free–free beam subjected to an in-plane compressive load. Joint is modelled as rotational spring, where the rotational spring stiffness governs the behaviour of the flexible joint. Variation of first five non-dimensional buckling loads of free–free beam with reference to the joint location as well as joint stiffness parameters are briefly presented. It is understood that looseness of the joint can significantly influence the buckling behaviour of free–free beam and plays an important role in accurately determining the buckling behaviour of jointed beams subjected to an in-plane compressive loads.

Published: April 2023

Abstract
Interest in nanocellulose has lately increased as a result of its benefits, such as renewable, biodegradable, high mechanical strength and valuable economically. In this regard, nanocellulose has been frequently employed as reinforcement for the enhancement of mechanical, thermal and biodegradation qualities of nanocomposite materials, such as thermoplastic starch. An overview of the use of pea starch that has been reinforced with nanocellulose for packaging and storage applications is given in this chapter. In comparison to standard sources of starch like maize, wheat and potatoes, it is consequently seen as a comparatively affordable source of starch. These composite polysaccharides (pea thermoplastic starch/nanocellulose) have the potential to replace traditional packaging composed of polymers derived from petroleum.
