Out of Sight, Out of Catalogue: The Neglected Grey Collection Medical MS G.4.c.14, Its Problematic Provenance, and Its Colonial Context
Authors: Foran Alec , Trembinski Donna
Published: February 2024

Cape Town National Library of South Africa’s Grey Collection MS G.4.c.14 is a fifteenth-century paper manuscript that contains three medical works and a series of recipes. This article briefly explores MS G.4.c.14’s contents before examining the story of the manuscript itself. Containing commentaries on Book IV, fen 4 of Avicenna’s Canon of Medicine by well-known instructor of surgery Leonardo di Bertipaglia (d. 1448), and by the more obscure Maffeus di Laudi (fl. 1392–1417), and a summary of Benevenutus de Grassus’s De oculis (ca. 11–13th c.), MS G.4.c.14 has the potential to add greatly to our understanding of medieval medicine. However, medieval manuscripts also have histories outside the texts they contain. An exploration of the provenance and history of MS G.4.c.14 brought to light how it moved from Rome to Cape Town, through the antics of an infamous book thief, Guglielmo Libri (1802–69), and its purchase by Sir George Grey, colonial governor of the Cape Colony in South Africa between 1854 and 1861. Although neither British in origin nor explicitly Christian in content, like many other European manuscripts, MS G.4.c.14 played an important role in informal processes of colonialism and cultural imperialism. We examine why MS G.4.c.14 had been ignored in research and catalogues of medieval medical and ophthalmological works for decades, despite being digitized and available at the Hill Museum and Manuscript Library in 1990 and being included in a modern catalogue of the Grey Collection since 2002. We suggest that looking outside Europe to find manuscripts like MS G.4.c.14 requires scholars to confront the colonialist history in the disciplines of medieval and manuscript studies. This has become even more important as technologies of digitization have made it possible to examine a manuscript without any recognition of its history or provenance.

Children with special educational needs in education field of Kazakhstan: problems and needs
Authors: Jangeldinova S.B.
Published: February 2024

The given article reviews researches surrounding education of children with special educational needs. It is noted that there is a lack of teachers who can work with inclusive children. The authors concluded that future foreign language teachers should be able to deal with children of different categories. The article analyzes the statistic data along Kazakhstan on inclusion. It is assumed that children with special educational needs do not need to be educated in special institutions: in a regular public school they can not only get a better education, but also successfully adapt to life, to realize the need for emotional and physical development. Inclusion is one of the goals of modern society, the transition from the standard system to the inclusive one in some countries is moving very slowly. There are many gaps in the modern school system, lack of staff, problems with the transition to equal education. All this gives reason to think about the preparation of future specialists to work with children with special needs in education. This study examines the situation in the country, which allows you to see the picture of modern inclusive education.

In this article, the authors consider the readiness of a future foreign language teacher to work with children with special educational needs in formal and non-formal education system, particularly, under what organizational and pedagogical conditions the activity of a future teacher will be effective. The article reveals the concepts of “formal” and “non-formal” education. With the introduction of inclusive education in the general education system of Kazakhstan the issue of foreign language teachers preparing to work with children with special educational needs came to the fore. The study of foreign languages in the country's schools begins in primary grades where the formation of a worldview, formation of language competencies starts, a foreign language teacher has to be able to realize the tasks in order to achieve the main goal in the classroom where children with special educational needs are the part of the educational process. In the system of formal and non-formal education it is necessary to create special conditions that help to implement the policy of inclusive education in our republic. There can arise various difficulties related to working with children with special educational needs in the pedagogical process, thus, in order to ensure the formation of the readiness of a foreign language teacher to work with children with special needs in formal and non-formal education system, the teacher is to overcome personal and professional difficulties in general educational organizations and providing educational organizations with favorable conditions for working with children with special educational needs

Authors: Искакова Ш.Г.
Published: February 2024

В современном образовании для совершенствования процессов обучения и преподавания применяется множество технологий, одной из которых является технология дополненной реальности, которая эффективно используется в образовательных учреждениях многих стран, в том числе и в Казахстане. Целью настоящего исследования — синтез эмпирических данных об эффективности применения технологии дополненной реальности при изучении иностранного языка. Для этой цели был выполнен метаанализ соответствующих эмпирических исследований, отвечающих ряду заранее установленных критериев приемлемости. В результате отбора литературных источников, в анализ было включено 6 исследований с участием 493 субъектов. Во всех включённых исследованиях оцениваемым показателем являлся словарный запас английского языка. Согласно результатам, у изучающих иностранный язык с использованием технологии дополненной реальности, величина эффекта (стандартизованная разность средних) была выше по сравнению с теми, кто проходил стандартное обучение. Однако различие не было статистически значимым (p=0,067). Сделан вывод об отсутствии значительной эффективности применения технологии дополненной реальности при изучении иностранного языка студентами университетов, школьниками и дошкольниками по сравнению со стандартными средствами обучения.
Theoretical foundations for the formation of students’ language learning strategies in the English language classroom
Authors: Baltabayeva А.К.
Published: February 2024

This article examines the effectiveness of language learning strategies in teaching English to secondary school students. Language learning strategies encompass a range of actions that actively contribute to a learner's self-development, enabling them to independently acquire new knowledge, assimilate social experience, and become a socially adept individual. In essence, these strategies help individuals become effective learners. The authors emphasize that in the current stage of education, fostering students' desire and ability to manage their own activities is a crucial aspect of the learning process in general education schools. This includes initiating actions, setting appropriate goals and tasks, making corrections, evaluating results, and planning future learning and cognitive activities. The authors identify the following types of language learning strategies: personal strategies (related to personal and professional self-determination), regulatory strategies (organizing students' learning activities through planning, prediction, correction, and evaluation), cognitive strategies (developing general academic and logical abilities), and communicative strategies (cultivating students' social competence). The article places particular emphasis on the educational nature of cognitive learning activities, which contribute to the formation of learners' new consciousness and increase their motivation to learn a foreign language. Various tasks are provided as examples to support these concepts within the article.

Espectro do autismo
Authors: Furtado Luis Achilles Rodrigues
Published: February 2024

Neste trabalho, pretendemos articular uma hipótese em torno do fenômeno da disseminação desenfreada de diagnóstico de transtorno do espectro autista a partir da lógica do fascínio que implica a foraclusão do sujeito. Aqui, abordamos a correspondência, sem mediação, entre o Ideal do eu e o objeto, considerando as indicações de Freud e de Lacan. A partir de uma leitura do texto “Nota sobre a criança” (Lacan, 1969/2003), pretendemos relacionar a clínica do autismo e a função de desconhecimento provocada pelo discurso capitalista das evidências científicas.
constituição do sujeito e a formação do analista

Published: February 2024

O objetivo deste artigo é fazer uma reflexão a partir de estudos vivenciados em uma rede de pesquisa e um cartel da Escola de Psicanálise do Fórum do Campo Lacaniano onde foi possível  discutir como a clínica com crianças, a partir dos conceitos de constituição do sujeito (alienação e separação), assim como o de travessia da fantasia infantil podem contribuir para a constituição do desejo do analista e da sua formação, através da análise pessoal e da sua implicação em uma instituição denominada como Escola, por Lacan.
truque analítico e o infantil que se formaliza em uma história de Dostoiévski
Authors: Fontenele Thalita Castello Branco
Published: February 2024

Este artigo parte de Um pequeno herói, livro de Dostoiévski escrito em 1849, que versa sobre o final da infância de um garoto. Na história, o artista antecipa questões que Freud só levou ao público décadas depois, e que concernem ao infantil ou ao que dele resta. Esse resto, desprezado pela ciência em sua formalização matemática, é material de trabalho do psicanalista. Aposta-se, portanto, em uma maneira de se servir da literatura em psicanálise que vá além do “roça-roça literário” denunciado por Lacan (1971), e que se volte àquilo que resta à maneira do “truque analítico”, um truque que é ao mesmo tempo lógico, poético e ético.
infantil é habitar poeticamente o mundo
Authors: Iuale Lujan
Published: February 2024

O infantil, contrariamente a tudo o que se pode pensar, é coisa séria. Sua configuração em tempos constitutivos portará as marcas sobre as quais se sustentará o enlaçamento. Freud enlaçou já muito cedo o inconsciente ao infantil e isso o levou a tentar constatar, uma e outra vez, como o infantil se apresentava nas modalidades próprias da satisfação. Porque para o falasser a satisfação será sempre perversa e polimorfa, na medida em que depende da parcialidade da pulsão. O infantil remete, além disso, à relação com o corpo, esse corpo afetado por lalíngua. As lalações, as palavras, as canções que ressoaram, a poética que habita a infância e configuram o infantil são alguns dos vieses que iremos abordar. Tomaremos o “brincar” como esse gesto político e constituinte do infantil.
Desejo do analista e transferência na análise online com crianças

Published: February 2024

A aparição de um novo vírus, que mobilizou o mundo inteiro, configurou-se como um acontecimento de real como nos diz Soler (2018), na medida em que marcou um antes e um depois com efeitos ainda incalculáveis. Diante dessa contingência, fomos convocados a responder não somente como sujeitos de nossa vida pessoal, mas também como analistas. Como dar seguimento às análises diante da urgência do isolamento social e do confinamento? Se, para muitos pacientes adultos e adolescentes, o trabalho de escuta a distância, de forma online, parecia poder se sustentar, como proceder com aqueles que transitam pela infância, já que sua produção coloca o corpo em cena através do brincar? A partir de recortes de dois casos clínicos, o presente artigo discute os limites e as possibilidades da análise online de crianças no contexto da pandemia, à luz dos conceitos fundamentais que orientam a clínica psicanalítica.
Incidence and management of traumatic vertebral artery injuries: wartime experience in Ukraine
Authors: Sirko Andrii , Cherednychenko Yurii , Dowlati Ehsan , Perepelytsia Vadym , Armonda Rocco A.
Published: February 2024

OBJECTIVE

Modern combat–related vertebral artery (VA) injuries are increasingly being diagnosed, but the management of such injuries remains controversial. The authors report the frequency and characteristics of combat-related penetrating VA injuries and the indications for endovascular treatment, as well as analyze their treatment outcomes.

METHODS

A 1-year prospective study was completed at a civilian medical center in Dnipro, Ukraine, in all patients with VA injuries sustained during the Russian invasion in the 1st year of war. The authors evaluated the location, type, and severity of the VA injuries and concomitant injuries, as well as the type of intervention and outcomes at 1 month.

RESULTS

In total, 279 wounded patients underwent cerebral angiography and 30 (10.8%) patients had VA injuries. All patients were male. There were 28 soldiers and 2 civilians with a mean age of 37.5 years. Four (13.3%) patients had Bissl grade I injuries, 4 (13.3%) had grade II injuries, 4 (13.3%) had grade III injuries (pseudoaneurysm), and 18 (60.0%) had grade IV injuries (occlusion). Four (13.3%) patients underwent emergency open surgical intervention. Fourteen (46.7%) patients underwent endovascular intervention. There was a significant relationship between the anatomical level of the VA injury and surgical intervention (p < 0.05). Endovascular intervention was correlated with the severity of vascular injury to the VA, with 12.5% of the patients receiving intervention for grade I and II lesions and 59.1% receiving intervention for grade III and IV lesions (p < 0.05). The overall mortality in the study group was 6.7% (n = 2), and both died of ischemic complications.

CONCLUSIONS

In modern armed conflicts, VA injuries are much more common than reported for previous wars. With the available modern endovascular technology, cerebral angiography is warranted for suspected VA injury and allows for both the diagnosis and treatment of these injuries. Whether endovascular intervention is performed depends on the level and severity of VA injury, severity of concomitant injuries, and presence of collateral circulation.

Authors: Joshi Janardan Prasad , Joshi Lila , Joshi Hira , Sah Ashok Prasad , Neupane Thaneshor
Published: February 2024

Idiopathic granulomatous mastitis is a rare benign breast disease of unknown aetiology mostly presenting as a breast abscess but not responding to usual conservative management with incision and drainage and frequently mimics breast cancer. We present a case 31-year-old female presented with complaints of right breast pain and redness who was initially diagnosed and treated as a case of breast abscess with repeated incision and drainage and antibiotics but did not improve. Later histopathology revealed granuloma with giant cell reaction and the patient was given a trial of steroids which showed no improvement. Wide local excision with a long course of broad-spectrum antibiotics was performed which led into remission. This case report highlights the importance of considering idiopathic granulomatous mastitis as differentials in non-responding breast abscesses. Histopathology for diagnosis and trial of wide local excision with a long course of broad-spectrum antibiotics as treatment may be done for management.

Published: February 2024

Introduction: Breast cancer is one of the most common cancers worldwide both in terms of incidence and mortality. Its incidence has been on an increasing trend in developing nations including Nepal, however, there is very limited evidence of its demographic profile in our setting. This study aimed to find out the prevalence of breast cancer among cancer patients visiting the Department of Internal Medicine of a tertiary centre.
Methods: A descriptive cross-sectional study was conducted among cancer patients visiting the Department of Internal Medicine of a tertiary care centre using retrospectively collected data from 1 August 2022 to 30 July 2023 after obtaining ethical approval from the Institutional Review Committee. Histopathologically confirmed cancer patients were included and those with incomplete and duplicated data were excluded. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval.
Results: Among 2067 cancer patients, the prevalence of breast cancer was 102 (4.93%) (4.00-5.87, 95% Confidence Interval). The mean age was 50.51±2.08 years. The most commonly affected age group was 40 to 60 years constituting 61 (59.80%) patients. Histologically, invasive breast cancer of no special type was the most common and was found in 91 (89.22%) patients.
Conclusions: The prevalence of breast cancer was similar to other studies done in similar settings.

A method for rapid estimation of residual stresses in metal samples produced by additive manufacturing
Authors: Fedorenko Alexey , Firsov Denis , Evlashin Stanislav , Fedulov Boris , Lomakin Evgeny
Published: February 2024

The mechanical methods for measuring residual stresses typically rely on so-called destructive techniques where some stress components can be determined based on part deflection after material removal (cutting, etching, drilling, etc.). While these methods don't provide a comprehensive representation of residual stresses within the entire part, they can be readily applied in most manufacturing labs. In this study, we propose an efficient method for determining residual stress within additively manufactured cylindrical samples of stainless steel. The method is based on the assumption of a relation between the axial component of residual stress (normal to cross-section) and the cylinder radius. The general form of this relation is proposed based on data from numerical simulations using linear, parabolic or piecewise approximations. The parameters for the proposed relation are defined using equilibrium equations for total force and moment. The proposed method relies on an experiment with a mechanical cut along the cylinder. Consequently, the deflection of the cylinder halves after the cut allows for obtaining the equivalent bending moment.

This study estimates the cost of occupational health risks in Pakistan’s diverse industries. The FFL quantile-decomposition method, the hedonic wage equation, and the VSL approach investigate the factors affecting wage differentials, risky job selection, and the total health risks cost in hazardous workplace settings. The wage differentials associated with perilous workplace conditions follow a quadratic trend, demonstrating that illiterate and impoverished workers are well-informed about potentially dicey settings. However, they are compelled to work as the stagnant labor market lacks alternatives. In contrast, skilled workers are compensated for occupational health risks because of the high demand. The estimated annual cost of health risks associated with potentially dangerous occupational settings is $5 million for industrial workers and $8 million for radiographers. Firms should build a framework for reducing work-related injuries, including employee self-assessment programs, accident prevention training, anti-smoking campaigns, stress management education, ergonomic management, and nutritional awareness to reduce workplace illnesses.
MACHINE LEARNING APPLICATION IN INVERSE DESIGN OF FEW-MODE FIBERS
Authors: Takialddin Al Smadi
Published: February 2024

The importance of optical fiber research is increasing due to its applications in the digital world, including components, sensors, and high data rate communication. Few-mode fiber (FMF) research is regenerating due to its high data rate transmission ability. This dissertation work proposes new designs of FMFs with updated material composition and geometry to establish weakly coupled spatial division multiplexing (SDM)/mode division multiplexing (MDM) links. The next generation of communication, 5G aims to connect people and things via intelligent networks, but current network architectures struggle to handle massive data traffic. The spatial domain of the fiber is highly useful for handling this massive data traffic. This work reviews the requirements of 5G networks and how they can be handled through spatial multiplexing and mode multiplexing through a few-mode optical fiber. The article demonstrates machine learning-based inverse modeling of the triangular-ring-core few-mode fiber profile with weak coupling optimization.

ialah salah satu sumber daya alam yang penting dan dibutuhkan oleh setiap makhluk untuk hidup yang dapat ditemukan disetiap tempat dipermukaan bumi. Penelitian ini bertujuan untuk mengetahui tutupan lahan disekitar sumber air beserta kualitas airnya dan mengetahui faktor yang mempengaruhi penggunaan sumber air di Taman Nasional Meru betiri. Metode yang digunakan pada penelitian ini adalah deskriptif. Terdapat 3 kalsifikasi tutupan lahan yaitu hutan lahan kering sekunder dan lahan pertanian kering campur semak serta satu klasifikasi tutupan lahan di desa penyangga yaitu permukiman. Sampel air yang memiliki tutupan lahan hutan kering sekunder memiliki dua parameter yang tidak memnuhi standar baku mutu yaitu parameter padatan tersuspensi total dan total coliform, sampel air yang memiliki tutupan lahan pertanian kering campur semak memiliki tiga parameter yang tidak memenuhi standar baku mutu yaitu padatan tersuspensi total, chemical oxygen demand dan total coliform, serta sampel yang memiliki tutupan lahan permukiman memiliki tiga parameter yang tidak memenuhi standar baku mutu yaitu warna, chemical oxygen demand dan total coliform. Perbedaan penggunaan sumber air oleh masyarakat disebabkan oleh faktor ekonomi dimana jumlah pendapat masyarakat yang tinggi menggunakan sumber air yang berasal dari sumur sedangkan jumlah pendapat masyarakat yang rendah memilih menggunakan sumber air dari mata air langsung.

В данной работе описывается оптическая плоская волноводная брэгговская решетка, которая включаетв себя кремниевый волновод, полимерный волновод и волновод кремний-на диэлектрике (КНД) в применении для биосенсоров. Темы настоящей статьи включают в себя проектирование и изготовление протравленной плоской волноводной одиночной брэгговской решетки и полимерной и кремний-на диэлектрике (КНД) плоской волноводной брэгговской решетки датчиков оптического преломления резонатора Фабри-Перо. Показано, что чем выше показатель преломления среды, тем больше изменяется резонансный пик датчика. Полость решетки Брэгга более чувствительна,чем одиночная брэгговская решетка в той же области длины волны. Поэтому брэгговская решетка с полостью более чувствительна, чем единственная брэгговская решетка. Кроме того, более короткая волноводная полость FP может обнаруживать гораздо большую чувствительность, чем более длинная, что будет перспективным для того, чтобы уменьшить датчики настолько наноразмерно, что можно обнаружить чрезвычайно низкую концентрацию молекул. Датчик, разработанный в данном исследовании, демонстрирует большую перспективность для применения в биомедицинской диагностике, такой как биосенсор и / или биохимические датчики мониторинга окружающей среды.

В качестве нанопористых шаблонов использовались трековыетемплейты SiO 2 /Si. Трековый темплэйт а-SiO 2 /Si-n был получен облучением ионами ксенона с энергией 200 МэВ, с флюенсами 10 7 –10 8 ионов/см 2 . Поверхность осажденных образцов исследовались с помощью сканирующего электронного микроскопа JSM 7500F.Для идентификации кристаллической структуры нанокластеров CdTe был выполнен рентгеноструктурный анализ. Нанокристаллы теллурида кадмия гексагональной фазы (вюрцит) формируются совместно с аморфной фазой. Расчеты размеров кристаллитов показали, что после отжига образцов СdTe при температуре 100 ◦ C приводит к изменениям нанористаллитов и увелечению степени кристалличности с доминированием аморфной фазы.
