A pragmatic approach to writer’s textual reflection
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Hyerim
Published: March 2023

Objectives The purpose of this study is to suggest a way to overcome the limitations of process-centered writing education by identifying the cognitive action in which the writer reflects on his/her text during the writing process.
Methods According to pragmatic semiotics, the interpreter of signs constitutes an immediate, dynamic and final interpretive body. In the writing situation, the writer is both a producer and an interpreter of signs, so he must be able to actively construct such interpretations. Each interpretive body can be specified as a text representation, a reader representation, and a discourse community representation. The cognitive strategies constituting each representation can be explained by the suitability theory, which is a model of pragmatic reasoning.
Results The composition of text representation is related to bottom-up reading, while reader representation and linguistic community representation are related to connotation and contextual meaning, respectively, both of which involve top-down reading. When the author reads the text he is writing for the purpose of text reflection, a conscious effort is required to exclude the meaning and background knowledge he is trying to convey. Therefore, when reflecting on text, it is necessary to distinguish between bottom-up reading and top-down reading, and to divide top-down reading into reader representation and linguistic community representation, and select and perform one reading method at a time.
Conclusions In the process of text reflection, the representations that can be constructed are related to the subject, purpose, reader, and language community, so it is necessary to teach them in sequence by rhetorical element. Just as the layers of reading are divided into factual, inferential, and critical understanding, it is possible to sequence the layers of my text reflection into three representations. Cognitive actions that form an inference model centered on each rhetorical element can be strategically made into educational content.
Fast quantum circuit cutting with randomized measurements
Authors: Lowe Angus , Medvidović Matija , Hayes Anthony , O'Riordan Lee J. , Bromley Thomas R. , Arrazola Juan Miguel , Killoran Nathan
Published: March 2023

We propose a new method to extend the size of a quantum computation beyond the number of physical qubits available on a single device. This is accomplished by randomly inserting measure-and-prepare channels to express the output state of a large circuit as a separable state across distinct devices. Our method employs randomized measurements, resulting in a sample overhead that is O~(4k/ε2), where ε is the accuracy of the computation and k the number of parallel wires that are "cut" to obtain smaller sub-circuits. We also show an information-theoretic lower bound of Ω(2k/ε2) for any comparable procedure. We use our techniques to show that circuits in the Quantum Approximate Optimization Algorithm (QAOA) with p entangling layers can be simulated by circuits on a fraction of the original number of qubits with an overhead that is roughly 2O(pκ), where κ is the size of a known balanced vertex separator of the graph which encodes the optimization problem. We obtain numerical evidence of practical speedups using our method applied to the QAOA, compared to prior work. Finally, we investigate the practical feasibility of applying the circuit cutting procedure to large-scale QAOA problems on clustered graphs by using a 30-qubit simulator to evaluate the variational energy of a 129-qubit problem as well as carry out a 62-qubit optimization.
Amplitude Ratios and Neural Network Quantum States
Authors: Havlicek Vojtech
Published: March 2023

Neural Network Quantum States (NQS) represent quantum wavefunctions by artificial neural networks. Here we study the wavefunction access provided by NQS defined in [Science, 355, 6325, pp. 602-606 (2017)] and relate it to results from distribution testing. This leads to improved distribution testing algorithms for such NQS. It also motivates an independent definition of a wavefunction access model: the amplitude ratio access. We compare it to sample and sample and query access models, previously considered in the study of dequantization of quantum algorithms. First, we show that the amplitude ratio access is strictly stronger than sample access. Second, we argue that the amplitude ratio access is strictly weaker than sample and query access, but also show that it retains many of its simulation capabilities. Interestingly, we only show such separation under computational assumptions. Lastly, we use the connection to distribution testing algorithms to produce an NQS with just three nodes that does not encode a valid wavefunction and cannot be sampled from.

Published: March 2023

CEL: Celem artykułu jest określenie wpływu upadłości jednego z polskich przedsiębiorstw na zadowolenie z pracy i płacy, a także percepcję sytuacji własnej, firmy i regionu przez byłych pracowników tej firmy, którzy zostali zatrudnieni przez nowego pracodawcę. METODA: Przeprowadzone badanie ankietowe objęło dwie grupy pracowników zatrudnionych w jednym przedsiębiorstwie: grupę z doświadczeniem upadłości pracodawcy oraz grupę pracowników bez doświad- czenia upadłości pracodawcy. Pozyskane dane były przedmiotem analizy współzależności z wykorzystaniem testu niezależności Pearsona oraz współczynnika V Craméra, a także analizy porównawczej rozkładów zmiennych w obu badanych grupach za pomocą testu Shapiro-Wilka. WYNIKI I WNIOSKI: Przeprowadzona analiza potwierdziła istnienie związku między doświadczeniem upa- dłości a zadowoleniem z pracy i płacy. Osoby, które doświadczyły upadłości poprzedniego pracodawcy, wy- kazują istotnie większe zadowolenie z wynagrodzenia oraz zadowolenie z pracy niż pozostałe osoby. W pierwszej grupie znajdują się też osoby mniej skłonne do zmiany miejsca pracy, które czuły się bardziej doceniane w miejscu pracy, a także lepiej oceniały perspektywy rozwoju w nowej firmie. Ponadto, zaobser- wowano istotne zróżnicowanie rozkładów odpowiedzi: w grupie pracowników z doświadczeniem upadłości hipoteza o rozkładzie normalnym została odrzucona dla większości zmiennych, podczas gdy w drugiej grupie pracowników tylko dla jednej. ORYGINALNOŚĆ I WKŁAD: Jest to pierwsze opracowanie w literaturze, które analizuje wpływ doświadczenia upadłości jednego przedsiębiorstwa na pracowników, którzy później grupowo zostali zatrudnieni w innym przedsiębiorstwie. SŁOWA KLUCZOWE: upadłość, bankructwo, zadowolenie z pracy, satysfakcja z płacy. JEL: J28, J63, J65
Amor, erotismo y enfermería. Una introducción al cuidado
Authors: Altamira-Camacho Ramiro
Published: March 2023

El cuidado es una práctica eminentemente humana, el cual –para la enfermería– se transforma en aquello que se aproxima a la vida de las personas, a la imperativa necesidad de sobrevivir, de inventar y de crear hábitos, formas subjetivas de interactuar que respondan a la salud propia y del otro. En este sentido, el objetivo de esta reflexión es dar a conocer el cuidado, desde la epistemología para la comprensión de este como condición humana; relacionada con las ciencias del espíritu y las ciencias naturales. Para llevar a cabo lo propuesto se realiza un análisis de los constructos disciplinares, partiendo de la definición de enfermería como una aproximación a la experiencia de salud humana y del cuidado como uno de los múltiples fenómenos de interés en la enfermería. Se problematizan los conceptos de erotismo y amor como un fundamento del cuidado y, por ende, también objeto de estudio de la disciplina enfermera. Ante esto, se concluye que el cuidado es una forma de amar(se) y el erotismo es el medio por el cual se genera el vínculo entre los seres humanos en los que se posibilita el cuidar, lugar donde la enfermera es parte de un saber y de los procesos que se llevan a cabo para lograr el cuidado.
Keyhole technology – advanced ﬁnite element analyses of the squeeze–off and cut–off tools
Authors: Buczkowski Ryszard , Budnicki Marek , Żyliński Bartek
Published: March 2023

We get some insight into the new construction and maintenance operations
so called keyhole technology which minimizes labour and restoration
costs compared with conventional practices. Because the concept is
relatively new to the public utility sector, there is a lack of
equipment/tools available that could perform the required services. The
ﬁnite element analyses using commercial package ABAQUS will be employed
to obtain the force needed to close the pipe. As a ﬁnal example we will
show the topology optimization of squeeze–off tool as the act of an
iterative process.

Published: March 2023

Sickle Cell Disease (SCD) is a group of inherited blood disorders caused
by a mutation in the beta subunit of hemoglobin (HbS). SCD is also known
as Sickle Cell Anemia (SCA). There are approximately 5000 Canadians
living with SCA including children. Pediatric SCA patient education can:
improve knowledge, decrease hospitalization, improve medication
possession ratio, lead to better SCA related functioning, and lower pain
impact. Innovative educational materials were developed to improve
knowledge and self-efficacy regarding illness management of patients and
parents/guardians. Patients (n=5; aged 8 – 18) with SCA and parents
(n=5) of patients (aged 0 – 18) were recruited via flyers sent directly
to patients and distributed through partner patient organization Sickle
Cell Awareness Network of Saskatchewan. Patient and parent focus groups
were held separately over Zoom to receive feedback for the video. An
additional interview was held for a participant that required
translation of the video. Audio recordings were transcribed using Zoom
and Otter.ai. Coding of transcripts was facilitated by NVivo (QSR
International Pty Ltd, 2022, release 1.6.2). Thematic analysis centred
around SCA management concepts relevant to the research aims. Important
themes that emerged included: ‘Age Appropriateness’, ‘Empowerment’,
‘Knowledge Gaps’, ‘Linguistic Accessibility’, ‘Medication Adherence’,
‘Strength in Community’ and ‘Transition to Adult Care’. The video was
well received, and “brought peace of mind”. Patient feedback was
incorporated into the final version of the educational materials.

Published: March 2023

Background While racial disparities in the clinical outcomes of
hematopoietic stem cell transplant (HSCT) patients have been explored,
racial disparities in quality of life (QoL) during the readjustment
phase after transplant has yet to be investigated in pediatric patients.
The objective of this study was to examine the role of patient race in
QoL at least two years after pediatric HSCT. Procedure We
conducted a retrospective chart review of patients under 21 years of age
at diagnosis that received an allogeneic transplant at our institution
between January 2007 and December 2017. Patient QoL was assessed using
the PedsQL TM 4.0 at least two years post-transplant. Patient
demographic, treatment, and transplant outcome data were obtained for
subsequent analysis, where patient race was categorized as either Black,
White, Hispanic, or Native American. Results Data were
collected on 86 pediatric patients who underwent HSCT. Forty patients
(46.5%) were non-Hispanic White, 29 (33.7%) Hispanic, 10 (11.6%)
Black, and 7 (8.1%) Native American. Where preliminary analyses
indicated a difference in QoL by patient race, there were no significant
differences in physical, emotional, social, and school functioning by
patient race after adjusting for transplant characteristics (age at
transplant, sex, diagnosis, donor type and conditioning regimen) and
determinants of socioeconomic status (insurance type, estimated
household income). Conclusions Pediatric patients had
comparable QoL, regardless of race, at a median of three years after
HSCT in our study cohort.

Published: March 2023

In search of new food-grade pH sensitive formulations, red beet extract rich in betacyanin was included in different inorganic matrices based on silica and aluminosilicate to improve the stability of the dye. By the direct method of encapsulation of the pigments in silica support, stabilizing agents such as inclusion complex forming ?-cyclodextrin and ascorbic acid were added. The post loading system assumes the synthesis of porous silica and aluminosilicate powders and the adsorption of the beet extract by these supports. The unloaded carriers were structurally and texturally characterized (X-ray diffraction, FTIR, N2-physisorption). The presence of betanin, approved as a red food colorant, was evidenced by UV?Vis spectroscopy in all the hosts. Color properties were investigated as well as the pH generated color variations of the powders exposed to ammonia in the head-space of a sealed vessel. The obtained results could widen the field of applications of beet extract, the prepared ecological formulations could provide added value to edible products packaging.

Bu çalışmada, Otonom Mobil Robotların (OMR) dönüşleri esnasında hareket doğrultusunda meydana gelen sapmalara avare tekerlerin etkisi incelenmiştir. Avare tekerlerin sürüş etkilerinin incelenmesi için CoppeliaSim programında bir OMR’nin analizi yapılmıştır. CAD programında tasarımı yapılan avare tekerleklerin Unified Robot Description Format (URDF) dosyası CoppeliaSim programına aktarılmıştır. OMR’nin ağırlığının dönüşlere etkisini incelemek için toplamda 75 ve 150 kg olmak üzere iki farklı ağırlıkta OMR kullanılmıştır. Analizlerde tekli, çiftli ve çift eksenli olmak üzere 3 farklı avare teker çeşidi kullanılmıştır. Avare tekerler arasında kıyaslama yapabilmek için diğer parametreler olan avare tekerin çapı, dönme ekseni ve toplam yüksekliği her bir durum için sabit tutulmuştur. Elde edilen sonuçlara göre, tekli avare tekerler dönüşlerde en fazla sapmaya neden olmaktadır. Çiftli avare tekerlerdeki sapmalar, tekli avare tekere göre daha düşük değerlerdedir. Bunula beraber, en düşük sapma miktarı çift eksenli avare tekerlerde olmaktadır. Ayrıca, çift avare teker ve çift eksenli avare teker bulunan OMR’lerde meydana gelen sapmalar tekli avare tekere oranla OMR’nin ağırlığından çok fazla etkilenmemektedir.
Investigation of a Rib Structure Effect on the Aerodynamic Performance of a Plain Flapped Symmetrical Airfoil
Authors: KAYA Ahmet Fatih
Published: March 2023

In this paper, two-dimensional computational fluid dynamics analyses were conducted to examine the rib effect on the performance of the NACA 0018 plain flapped airfoil. A mesh independence study was carried out and the Spalart-Allmaras turbulence model was selected for validation. Four various airfoil models were designed: M1 (airfoil without plain flap and rib structure), M2 (airfoil with rib structure), M3 (airfoil with a plain flap) and M4 (airfoil with a rib structure and plain flap). The performance of designed airfoils was calculated in terms of lift-to-drag (C_L/C_D) ratio. As a result, the plain flap significantly increased the lift coefficient (C_L) and drag coefficient (C_D). While the rib structure enhanced the aerodynamic performance of the non-flapped airfoil when the attack angle was greater than 12°, it increased the performance of the plain flapped airfoil at almost all attack angles. Furthermore, it was seen that the rib structure decreased C_D values of plain flapped airfoil at all attack angles and increased C_L values of plain flapped airfoil when the attack angle was greater than 2°.

Published: March 2023

Defects such as porosity and cracking are serious problems in the joining of aluminium and its alloys by melt welding methods. In this case, it is important that the aluminum pairs are welded by friction stir welding (FSW), which is depend on joining at a temperature below the melting temperature by means of a stirrer pin. In this study, AA5182 pairs were joined in the different welding parameters by FSW. The effects of tool pin profily, feed rate and rotation speed on the temperature, force and vibration formed during welding were experimentally investigated. As the rotation speed rised, the temperature increased and the welding force decreased. But, with increasing feed rate, the temperature decreased and welding force and vibration have increased. Mechanical properties of the joints were adversely affected by low temperature, high welding force and high vibration.

The aim of this multi-centre French retrospective study was to identify severe, i.e. crusted and profuse, scabies patients. Records were retrieved from 22 Dermatology or Infectious Diseases departments in the Ile-de-France from January 2009 to January 2015 to characterize epidemiology, demography, diagnosis, contributing factors, treatment features, and outcomes in severe scabies. A total of 95 inpatients (57 crusted and 38 profuse) were included. A higher number of cases was observed among elderly patients (>75 years), mostly living in institutions. Thirteen patients (13.6%) reported a history of previously treated scabies. Sixty-three patients (66.3%) had been seen by a previous practitioner for the current episode (up to 8 previous visits). Initial misdiagnosis (e.g. eczema, prurigo, drug-related eruptions, psoriasis) was documented in 41 patients (43.1%). Fifty-eight patients (61%) had already received 1 or more previous treatments for their current episode. Forty percent received corticosteroids or acitretin for an initial diagnosis of eczema or psoriasis. Median time from the onset of symptoms to the diagnosis of severe scabies was 3 months (range 0.3–22). Itch was present in all patients at diagnosis. Most patients (n=84, 88.4%) had comorbidities. Diagnostic and therapeutic approaches varied. Complications occurred in 11.5% of cases. To date, there is no consensus for diagnosis and treatment, and future standardization of is required for optimal management.

Authors: Sarsah Emmanuel A. , Yunus Adams , Bawa Abdul-Rahim , Akanbasiam Joshua A.
Published: March 2023

Monthly average daily global solar radiation data are essential for the design and study of solar energy systems. The performance and accuracy of eleven models for the estimation of monthly average global solar radiation were compared in this study. Nineteen months (Nov 2020 – May 2022) ground measurement data consisting of monthly mean daily sunshine duration, relative humidity, minimum and maximum temperatures, and global solar radiation collected from the Lawra Solar Plant were used. The models were compared using statistical indices. According to the indices, most of the models were in reasonably good agreement with the measured data. Two model equations, however, were found to have the highest accuracy and can thus be used to estimate monthly average global solar radiation in Lawra and other places with similar climatic conditions where radiation data is unavailable.

Authors: Aufa Gustia
Published: March 2023

Writing this literature study is motivated by the low learning outcomes of students in elementary schools due to the less optimal application of the learning approach and the lack of visible application of the characteristics of integrated thematic learning. In the learning process the teacher still uses conventional teacher-centered teaching methods so that students become passive and the potential in students does not develop. This study aims to analyze the application of a scientific approach to integrated thematic learning in grade II elementary schools. The scientific approach is an approach in the learning process that is designed in such a way that students actively construct concepts, laws or principles through observing stages (to identify or find problems), formulate problems, propose or formulate hypotheses, collect data with various techniques, analyze data, draw conclusions and communicate the concepts, laws or principles found. The method of writing scientific papers is to use literature studies, first the researcher formulates a research problem, then continues by tracing existing and relevant research for analysis. The technique of collecting data using non-tests is by searching for accredited electronic journals through Google Scholar. By collecting 15 accredited journals that are relevant to the topic, then analyzed the extent to which the improvement of student learning outcomes with the application of a scientific approach in learning.

Padang City waters are one of the waters that have very promising potential for fishermen. This study aims to obtain potential areas for catching large pelagic fish which are analyzed using fashionable image data of chlorophyll a and SST. This research was carried out in November 2021. This research covered the period June, July and August, on June 9 potential zones for large pelagic fish were scattered, based on the distribution of potential large pelagic fish zones a distance of beat tween 1,000 meters to 5,000 resulted in 5 zones of potenzones for large pelagic fish and a distance of 1,000 meters to 10,000 or sea II produces 4 zones indicating the potential for large pelagic fish. In July the potential zone for large pelagic fish increased by 14 potential zones for large pelagic fish from a distance of 5. As a result, the distribution of sea surface temperature increases every month and the distribution of chlorophyll tends to crease. Based on the results of the interpolation of the potential for large pelagic fish, August is a month that has the potential for large pelagic fish catching zones, in the distribution of potential fish zones in the waters of Padang City, the average sea depth is between 10 meters and 50 meters. Based on tests of the accuracy of the distribution of fishing vessels in the waters of the City of Padang, only 5,000 meters from the shoreline, this has resulted in fewer fisherfewerbeing able to explore the potential spread across the waters of the City of Padang because there are no ships with engines with tonnage or wide cruising to be able to explore existing the potential.

Давление гравитационного поля и вакуума определяет течение времени под поверхностью Земли.
Authors: Беляев Владимир
Published: March 2023

Давление вакуума определяется из геометрии пространства вокруг локальной гравитационной системы согласно идее А. Д. Сахарова о «метрической упругости» пространства, т.е. возникновении обобщенной силы, предотвращающей его искривление. Предполагается, что энергия, эквивалентная гравитационному дефекту масс, расходуется на деформацию вакуума. Определяется гравитационное воздействие вещества на вакуум в случае слабо гравитирующего статического центрально-симметричного распределения вещества. Противоположное по знаку давление вакуума соответствует решению уравнений Эйнштейна для такого источника гравитации. Полученная метрика используется для определения течения времени под поверхностью Земли.
