Authors: Goodrich George M. , Gundlach Richard B , Tuttle Robert B. , White Charles V. 
Published: December 2021

AbstractThe information provided in this article is intended for those individuals who want to determine why a casting component failed to perform its intended purpose. It is also intended to provide insights for potential casting applications so that the likelihood of failure to perform the intended function is decreased. The article addresses factors that may cause failures in castings for each metal type, starting with gray iron and progressing to ductile iron, steel, aluminum, and copper-base alloys. It describes the general root causes of failure attributed to the casting material, production method, and/or design. The article also addresses conditions related to the casting process but not specific to any metal group, including misruns, pour shorts, broken cores, and foundry expertise. The discussion in each casting metal group includes factors concerning defects that can occur specific to the metal group and progress from melting to solidification, casting processing, and finally how the removal of the mold material can affect performance.

Lexical-semantic peculiarities of Andrii Kokotiukha’s detective novels
Authors: Maiboroda Nataliia 
Published: December 2021

The article touches upon various lexical-semantic peculiarities of Andrii Kokotiukha’s detective novels, specifically the nomination of people – characters of the novel. Such research are presented mostly from the point of view of literary studies. Scientists studied peculiar features of composition, genre, and plot of detective novels. The question of language and style of detective novels would uncommonly become a subject of research as they are regarded to as so-called mass literature, that is one that is focused on literature preferences of a wide circle of readers, in other words – it is a popular, entertaining, trivial literature.
Linguistic research of detective works were mostly done on the material of literary texts of English and French languages, Ukrainian detectives were not a subject of such analysis. Questions of influence of genre peculiarities on the choice of linguistic units was also left beyond attention of researchers, which predetermines the relevance of the research. The source basis of the research consists of detective novels by Andrii Kokotiukha – one of the most notable Ukrainian detective authors. That is a series of retronovels, where the action takes place at the beginning of XX century in Lviv, and three novels about the modern period as well.
The aim of the work is to explore lexical units that denote a person in Andrii Kokotiukha’s detective novels in terms of their expressive functions depending on the aim and genre features. Vocabulary of denomination of people is widespread in Kokotiukha’s works. Specifics of detective novels involves agile, dynamic nature of vocabulary and their text.
Semantics of people’s names is diverse: its affiliation to the biological genus of humans; gender; age; family status; profession and occupation; status from the point of view of law; class and social structure of Ukrainian society; social status; financial situation; nationality or confession; affiliation to political parties; names of dead people, external signs; temporary sign. The author frequently uses descriptive compounds, metaphors, jargon, and colloquial language. A distinctive method of nominating a person which, according to genre requirements, creates mystery and enigma of presentation, is descriptive compounds with pronouns. Quantitative ratio of lexical groups mentioned depends on the peculiarities of the plot of specific novel.
Nomination of people in A. Kokotiukha’s detective novels are components of dynamic and static descriptions, help convey the cultural-historical background, create the appropriate emotional tint. That is one of the elements which ensures that the text corresponds to the canons of detective genre.
Alfred Döblin vs. Bertolt Brecht: reception of the genre Lehrstück in A. Döblin’s drama
Authors: Fedorenko Larysa 
Published: December 2021

The article is devoted to the drama of Bertolt Brecht and Alfred Döblin. On the material of A. Döblin’s play «The Marriage» analyzes the typological factors of the genre Lehrstück («learning» or «didactic» play), which became widespread as Brecht’s authorial innovation. The purpose of the article: on the basis of comparative analysis of Lehrstück by B. Brecht and the play «The Marriage» by A. Döblin to explore their formal and poetic factors and to conclude about the common and distinctive features of artistic and aesthetic intention of the genre Lehrstück in the works of both playwrights.
The source base of the research is represented by literary studies of Günter Hartung, Jan Knopf, Klaus-Dieter Krabiel, Heiner Müller, Rainer Steinweg, Bernhard Klaus Tragelehn, Florian Vaßen, Oleksandr Chirkov. To achieve this goal, the following research methods were used: cultural-historical, comparative-historical, structuralsemantic, descriptive, literary analysis and synthesis. The study presents the main stages of the genre in the work of Brecht and focuses on the initial period of origin of the «learning» or «didactic» play, which is also relevant to the drama of A. Döblin. The play «The Marriage» contains three scenes, a prologue and an interlude. Thematically, all the scenes are united by a common plot core – showing the breakup of marriage and family due to external circumstances. Family and marital relationships fail regardless of social status or financial status. Results and conclusions: The article proves that A. Döblin’s play «The Marriage» has a number of aesthetic and typological features that make it related to Brecht’s «didactic» plays: rejection of theatrical scenery, props, that is, everything that creates a theatrical illusion; the presence of epic elements and music as components of drama; use of text and illustrative projections, songs, recitatives with musical accompaniment; presence of a speaker (commentator) and a choir; the inclusion of the author’s commentary, which states the theme and issues of the drama, as well as explains how the play is constructed, emphasizes the probable educational, educational, instructive influence; the presence of director’s remarks that explain the options for the stage embodiment of the play; the ability to improvise, modify the text of the play and release individual scenes according to the purpose and type of production. A generalized analysis of the existing typological characteristics gives grounds to consider the play «The Marriage» by A. Döblin as a conceptual imitation and / or continuation of the theory and practice of the author’s genre Lehrstück B. Brecht.
Existent essence of experimental modern Ukrainian prose: «DNK» (Serhiy Zhadan, Yuriy Vynnychuk, Irena Karрa, Fozzi, Andriy Kokotyukha, Volodymyr Rafaenko and Max Kidruk)
Authors: Chonka Tetiana 
Published: December 2021

One of the characteristic features of modern Ukrainian literature is its innovative exploration at all levels such as genre-thematic, linguistic-stylistic, etc. The subject of this scientific investigation is an experimental project (family saga, novel in short stories) «DNК», the authors of which are seven original but different authors – Sergei Zhadan, Yuri Vynnychuk, Irena Karpa, Fozzy, Andrei Kokotyukha, Vladimir Rafaenko and Max Kidruk.
The object of our study is the genre-style and ideological-thematic characteristics of each novel and their ideological and semantic integrity. Given the idiosyncrasy of each of the authors, we made a figurative analysis of the characters which includes their worldview, behavior, dreams and language.
In the course of the research we can state that the chronotope of events, language, stylistic and genre peculiarities are all aimed at comprehensive disclosure of the life of Ukraine and Ukrainians at the peaks of history. It is the anthropological principle of analysis of these works that should be the starting point today and now, when not only our country, but humanity in general is in a situation of humanitarian catastrophe.
The problem of all times and peoples is the unwillingness to listen to the artistic word, to the efforts of artists (intuitive, subconscious, and sometimes specifically oriented) to force their contemporaries to think about specific values and priorities, personal and national, taking into account the experience of past generations. We are convinced that the emergence of «DNК» is due to such a specific existential need, that is, the need for ueverybody to rethink the lessons of history with the necessary conclusions.
Noninvasive disconnection of targeted neuronal circuitry sparing axons of passage and nonneuronal cells

Published: December 2021

OBJECTIVE
Surgery can be highly effective for the treatment of medically intractable, neurological disorders, such as drug-resistant focal epilepsy. However, despite its benefits, surgery remains substantially underutilized due to both surgical concerns and nonsurgical impediments. In this work, the authors characterized a noninvasive, nonablative strategy to focally destroy neurons in the brain parenchyma with the goal of limiting collateral damage to nontarget structures, such as axons of passage.

METHODS
Low-intensity MR-guided focused ultrasound (MRgFUS), together with intravenous microbubbles, was used to open the blood-brain barrier (BBB) in a transient and focal manner in rats. The period of BBB opening was exploited to focally deliver to the brain parenchyma a systemically administered neurotoxin (quinolinic acid) that is well tolerated peripherally and otherwise impermeable to the BBB.

RESULTS
Focal neuronal loss was observed in targeted areas of BBB opening, including brain regions that are prime objectives for epilepsy surgery. Notably, other structures in the area of neuronal loss, including axons of passage, glial cells, vasculature, and the ventricular wall, were spared with this procedure.

CONCLUSIONS
These findings identify a noninvasive, nonablative approach capable of disconnecting neural circuitry while limiting the neuropathological consequences that attend other surgical procedures. Moreover, this strategy allows conformal targeting, which could enhance the precision and expand the treatment envelope for treating irregularly shaped surgical objectives located in difficult-to-reach sites. Finally, if this strategy translates to the clinic, the noninvasive nature and specificity of the procedure could positively influence both physician referrals for and patient confidence in surgery for medically intractable neurological disorders.

Published: December 2021

OBJECTIVE
The aim of this study was to identify trends in the demographic constitution of applicants and matriculants to neurological surgery based on race, ethnicity, and gender.

METHODS
The authors conducted a cross-sectional study using compiled demographic data obtained from the Association of American Medical Colleges. Trends analyzed included proportional changes in race, ethnicity, and gender of applicants and matriculants to neurosurgical residency programs from academic years 2010–2011 to 2018–2019.

RESULTS
A total of 5100 applicants and 2104 matriculants to neurosurgical residency programs were analyzed. No significant change in the percentage of overall women applicants (+0.3%, 95% CI −0.7% to 1.3%; p = 0.77) or in the percentage of women matriculants (+0.3%, 95% CI −2.2% to 2.9%; p = 0.71) was observed. For applicants, no change over time was observed in the percentages of American Indian or Alaska Native (AI/AN) men (0.0%, 95% CI −0.3% to 0.3%; p = 0.65); Asian men (−0.1%, 95% CI −1.2% to 1.1%; p = 0.97); Black or African American men (−0.2%, 95% CI −0.7% to 0.4%; p = 0.91); Hispanic, Latino, or of Spanish Origin men (+0.4%, 95% CI −0.8% to 1.7%; p = 0.26); White men (+0.5%, 95% CI −2.1% to 3.0%; p = 0.27); Asian women (+0.1,% 95% CI −0.9% to 1.1%; p = 0.73); Black or African American women (0.0%, 95% CI −0.6% to 0.5%; p = 0.30); Hispanic, Latino, or of Spanish Origin women (0.0%, 95% CI −0.4% to 0.4%; p = 0.71); and White women (+0.3%, 95% CI −1.1% to 1.7%; p = 0.34). For matriculants, no change over time was observed in the percentages of AI/AN men (0.0%, 95% CI −0.6% to 0.6%; p = 0.56); Asian men (0.0%, 95% CI −2.7% to 2.7%; p = 0.45); Black or African American men (−0.3%, 95% CI −1.4% to 0.8%; p = 0.52); Hispanic, Latino, or of Spanish Origin men (+0.6%, 95% CI −0.8 to 2.0%; p = 0.12); White men (−1.0%, 95% CI −5.3% to 3.3%; p = 0.92); Asian women (+0.1%, 95% CI −1.3% to 1.5%; p = 0.85); Black or African American women (0.0%, 95% CI −0.6% to 0.7%; p = 0.38); Hispanic, Latino, or of Spanish Origin women (−0.1%, 95% CI −0.7% to 0.5%; p = 0.46); and White women (+0.3%, 95% CI −2.4% to 3.0%; p = 0.70).

CONCLUSIONS
Despite efforts to diversify the demographic constitution of incoming neurosurgical trainees, few significant advances have been made in recent years. This study suggests that improved strategies for recruitment and cultivating early interest in neurological surgery are required to further increase the diversification of future cohorts of neurosurgical trainees.

Published: December 2021

OBJECTIVE
The COVID-19 pandemic caused a significant disruption to residency recruitment, including a sudden, comprehensive transition to virtual interviews. The authors sought to characterize applicant experiences and perceptions concerning the change in the application, interview, and match process for neurological surgery residency during the 2020–2021 recruitment cycle.

METHODS
A national survey of neurosurgical residency applicants from the 2020–2021 application cycle was performed. This survey was developed in cooperation with the Society of Neurological Surgeons (SNS) and the American Association of Neurological Surgeons Young Neurosurgeons Committee (YNC) and sent to all applicants (n = 280) who included academic video submissions to the SNS repository as part of their application package. These 280 applicants accounted for 69.6% of the total 402 neurosurgical applicants this year.

RESULTS
Nearly half of the applicants responded to the survey (44.3%, 124 of 280). Applicants favored additional reform of the interview scheduling process, including a centralized scheduling method, a set of standardized release dates for interview invitations, and interview caps for applicants. Less than 8% of students desired a virtual-only platform in the future, though the majority of applicants supported incorporating virtual interviews as part of the process to contain applicant costs and combining them with traditional in-person interview opportunities. Program culture and fit, as well as clinical and research opportunities in subspecialty areas, were the most important factors applicants used to rank programs. However, subjective program "fit" was deemed challenging to assess during virtual-only interviews.

CONCLUSIONS
Neurosurgery resident applicants identified standardized interview invitation release dates, centralized interview scheduling methods, caps on the number of interviews available to each candidate, and regulated opportunities for both virtual and in-person recruitment as measures that could significantly improve the applicant experience during and effectiveness of future neurosurgery residency application cycles. Applicants prioritized program culture and "fit" during recruitment, and a majority were open to incorporating virtual elements into future cycles to reduce costs while retaining in-person opportunities to gauge programs and their locations.
ДІАГНОСТИКА ВИХІДНОГО РІВНЯ СФОРМОВАНОСТІ ІНФОРМАЦІЙНО-ЦИФРОВОЇ КОМПЕТЕНТНОСТІ МОЛОДШИХ ШКОЛЯРІВ
Authors: Стєганцева Валерія 
Published: December 2021

Стаття присвячена виявленню вихідного рівня сформованості у першокласників інформаційно-цифрової компетентності як наукового орієнтиру процесу формування зазначеної компетентності у початковій школі. Виходячи з трикомпонентної структури інформаційно-цифрової компетентності молодших школярів було виділено три відповідних критерія оцінювання її рівня сформованості. Перший критерій – когнітивний – був акцентований на сформованості певної сукупності знань та вмінь про джерела інформації і способи роботи з нею, знанні понять, пов’язаних із інформацією. Другий критерій – технологічний – характеризував переважно технічні знання, вміння та навички використання комп’ютера та інших цифрових пристроїв. Третій критерій – аксіологічний – уключав до себе ціннісні (правові, етичні) аспекти он-лайн спілкування. Важливо відзначити, що діагностика сформованості у першокласників інформаційно-цифрової компетентності уключає до себе не лише письмове анкетування, але й включене спостереження, бесіди, усне інтерв’ю, що дозволило максимально уточнити зміст відповідей на письмове опитування. Аналіз даних за когнітивним критерієм дозволяє заключити, що першокласники мають найбільш загальне уявлення про джерела інформації, до яких відносяться різні цифрові пристрої, мінімальний досвід володіння окремими, найпростішими функціями, розуміють їх значення для себе як нового джерела інформації поверхнево, але орієнтуються в шкільному інформаційному просторі. У контексті технологічного критерію першокласники проявляють вміння та навички володіння простими цифровими технологіями, вміють застосовувати найпростіші та розповсюджені комп’ютерні та мобільні пристрої для розв’язання елементарних завдань, швидко освоюють способи створення простого контенту у простих форматах. Аксіологічний критерій дозволив виявити зростання прагнення першокласників до удосконалення своєї інформаційно-цифрової компетентності як значущої для них особистісної життєвої цінності. Комп’ютерне середовище розглядається ними як необхідний складник їх навчальної та позанавчальної діяльності.
Relationship of Serum Tau Levels with Cognitive Functions and Factors Affecting The Cognitive Function Decrease in Parkinson's Disease Patients
Authors: Busra Meldayeni , Yuliarni Syafrita  , Hendra Permana  
Published: December 2021

Introduction: Cognitive impairment is a non-motor symptom of Parkinson's disease (PD) which occurs as the disease progresses and affects quality of life. Many efforts have been developed in early detection of cognitive disorders, one of which is the examination of tau protein biomarkers, where the tau protein that undergoes pathological changes to form neurofibrillary tangles (NFTs) is found in Alzheimer's disease and PD and plays a role in cognitive impairment. However, the role of tau in PD is still controversial. This study aims to assess the relationship between serum tau levels and cognitive function and the factors that affect cognitive function in PD patients.
Methods: This cross-sectional design was conducted at the RSUP DR. M Djamil Padang. During the period March to August 2020, 62 research subjects were obtained. Cognitive function examination was carried out by using the MoCA-Ina test and examination of serum tau levels using the Elisa method. The relationship between categorical variables was tested by Chi square and differences in serum tau levels in the group with and without cognitive impairment were tested with the Mann Whitney test, considered statistically significant if the p value <0.05.
Results: With Moca Ina examination, it was found that 67.7% of patients had impaired cognitive function. The mean serum tau level was 198.004 ± 162.69 ng / L.There was a significant relationship between education level and degree of disease with cognitive function (p <0.05) and there was no difference in mean serum tau levels between groups with and without cognitive impairment.
Conclusion: There is a significant relationship between education level and degree of disease with cognitive function and there is no difference in mean serum tau protein levels between the cognitive impaired group and the cognitive normal group.
Arrhythmic Risk Assessment of Hypokalaemia Using Human Pluripotent Stem Cell-Derived Cardiac Anisotropic Sheets
Authors: Gurung Bimal , Tse Gary , Keung Wendy , Li Ronald A. , Wong Wing Tak 
Published: December 2021

Introduction: Hypokalaemia, defined as an extracellular concentration of K+ below 3.5 mM, can cause cardiac arrhythmias by triggered or re-entrant mechanisms. Whilst these effects have been reported in animal and human stem cell-based models, to date there has been no investigation in more complex structures such as the human ventricular cardiac anisotropic sheet (hvCAS). Here, we investigated arrhythmogenicity, electrophysiological, and calcium transient (CaT) changes induced by hypokalaemia using this bioengineered platform.Methods: An optical mapping technique was applied on hvCAS derived from human pluripotent stem cells to visualize electrophysiological and CaT changes under normokalaemic (5 mM KCl) and hypokalaemic (3 mM KCl) conditions.Results: Hypokalaemia significantly increased the proportion of preparations showing spontaneous arrhythmias from 0/14 to 7/14 (Fisher’s exact test, p = 0.003). Hypokalaemia reduced longitudinal conduction velocity (CV) from 7.81 to 7.18 cm⋅s−1 (n = 9, 7; p = 0.036), transverse CV from 5.72 to 4.69 cm⋅s−1 (n = 12, 11; p = 0.030), prolonged action potential at 90% repolarization (APD90) from 83.46 to 97.45 ms (n = 13, 15; p &lt; 0.001), increased action potential amplitude from 0.888 to 1.195 ΔF (n = 12, 14; p &lt; 0.001) and CaT amplitude from 0.76 to 1.37 ΔF (n = 12, 13; p &lt; 0.001), and shortened effective refractory periods from 242 to 165 ms (n = 12, 13; p &lt; 0.001).Conclusion: Hypokalaemia exerts pro-arrhythmic effects on hvCAS, which are associated with alterations in CV, repolarization, refractoriness, and calcium handling. These preparations provide a useful platform for investigating electrophysiological substrates and for conducting arrhythmia screening.
