ВЛИЯНИЕ РЕЦЕПТУРНОЙ КОМПОНОВКИ НА СИЛУ ВЗРЫВА НАНОТЕРМИТНОЙ КОМПОЗИЦИИ CuO/Al/1Me-3H
Authors: Гордеев В.В. , Казутин М.В. , Козырев Н.В. 
Published: November 2021

Синтезированное в ИПХЭТ СО РАН низкочувствительное высокоэнергетическое вещество 1-метил-3-нитро-1,2,4-триазол (1Ме-3Н) рассматривается как перспективная добавка, способная увеличить силу взрыва нанотермитных композиций. В работе приведены результаты исследования силы взрыва (F) нанотермитной композиции CuO/Al/1Me-3H в зависимости от содержания 1Ме-3Н. Исследован ряд составов различной рецептурной компоновки: I – соотношение компонентов тройной смеси CuO/Al/1Me-3H соответствовало максимальной расчетной теплоте взрыва композиции (Q) при заданном содержании 1Ме-3Н; II – соотношение компонентов тройной смеси соответствовало максимальному расчётному значению давления (P), развиваемому при горении композиции в замкнутом объеме; III –соотношение компонентов базовой нанотермитной пары CuO/Al (79/21 % масс.), соответствующее максимальному расчетному значению Q, оставалось постоянным в тройной смеси; IV – соотношение компонентов базовой нанотермитной пары CuO/Al (76/24 % масс.), соответствующее максимальному расчетному значению P, оставалось постоянным в тройной смеси. Для всех типов компоновки выявлен экстремальный характер зависимости силы взрыва от содержания 1Ме-3Н, при этом максимальные значения F наблюдаются при содержании добавки 5 % для компоновки I (F = 107 %), 10 % для компоновки II (F = 128 %), 25 % для компоновки III (F = 151 %) и 30 % для компоновки IV (F = 147 %).
The low-sensitivity high-energy substance 1-methyl-3-nitro-1,2,4-triazole (1Me-3H), synthesized at the IPCET SB RAS, is considered as a promising additive capable of increasing the explosion force of nanotermitic compositions. The paper presents the results of a study of the explosion force (F) of the nanothermic composition CuO / Al / 1Me-3H, depending on the content of 1Me-3H. A number of compositions of various prescription configurations were investigated: I - the ratio of the components of the ternary mixture CuO/Al/1Me-3H corresponded to the maximum calculated heat of explosion of the composition (Q) at a given content of 1Me-3H; II - the ratio of the components of the ternary mixture corresponded to the maximum calculated value of the pressure (P) developed during the combustion of the composition in a closed volume; III — the ratio of the components of the base nanothermite pair CuO/Al (79/21 %), corresponding to the maximum calculated value of Q, remained constant in the ternary mixture; IV - the ratio of the components of the base nanothermite pair CuO / Al (76/24 %), corresponding to the maximum calculated value of P, remained constant in the ternary mixture. For all types of prescription configurations, an extreme nature of the dependence of the force explosion on the content of 1Me-3H was revealed, while the maximum values of F are observed at an additive content of 5% for configuration I (F = 107%), 10% for configuration II (F = 128%), 25% for configuration III (F = 151%) and 30% for configuration IV (F = 147%).
Новейший способ обмена метриками
Authors: Хомяков И.А. 
Published: November 2021

Сбор метрик программного обеспечения является фундаментальной деятельностью, которая необходима для проведния практически любого эмпирического исследования в области программной инженерии. Однако, даже при наличии широкого спектра инструментов, сбор таких фундаментальных данных по-прежнему занимает много времени. Более того, каждый исследователь собирает практически одни и те же данные (например, метрики CK, цикломатическая сложность МакКейба и т.д.) из практически одних и тех же проектов (например, из известных проектов с открытым исходным кодом). Объем такой дублирующей работы, выполняемой в сообществе, уменьшает усилия, которые исследователи могут потратить на наиболее ценную часть своих исследований, такую как разработка новых теорий и моделей и их эмпирическая оценка. В данной работе предлагается новый подход для сбора и обмена данными метрик программного обеспечения, позволяющий сотрудничать исследователям и сократить количество напрасных усилий в сообществе разработчиков программного обеспечения. Мы стремимся достичь этой цели, предлагая Формат обмена программными метриками (SMEF)и REST API для сбора, хранения и обмена данными метрик программного обеспечения.
In almost every empirical software engineering study, software metrics collection is a fundamental activity. Although many tools exist to collect this data, it still takes a considerable amount of time. In addition, almost all researchers collect essentially the same data (e.g., CK metrics, McCabe Cyclomatic Complexity, etc.) from essentially the same sources (e.g., well-known open-source projects).Having so much duplication of work done within a community reduces the amount of time that researchers can spend developing new ideas and evaluating them empirically, which is the most valuable part of their research. In this paper, we propose a novel approach for getting and sharing software metrics data that will allow them to collaborate and reduce the amount of wasted effort. SMEF, a file format for exchanging software metrics information, and a REST API, targeted at this objective, are proposed in this paper.

Показано, что динитразовая кислота легко взаимодействует с 1-амино-1,2,3-триазолом с количественным выходом образуя соответствующую высокоэнергетическую ионную соль. В ходе процесса солеобразования используется более безопасный и доступный растворитель, чем описано в литературе для ионных солей динитразота на основе различных триазолов.
It was shown that dinitratic acid easily interacts with 1-amino-1,2,3-triazole in quantitative yield to form the corresponding high-energy ionic salt. During the salt formation process, a safer and more affordable solvent is used than described in the literature for dinitrazot ionic salts based on various triazoles.
“Breaking Good”: Mentoring for Teacher Induction at the Workplace
Authors: Orland Barak Lily 
Published: November 2021

Given the dissonant and complex character of induction for novices at the workplace, I propose a conception of mentoring that focuses on mitigating misalignments between novices’ developmental stage and the socializing characteristics and pressures of workplace induction. Drawing on extant research and conceptualization, including my own research on mentoring for teacher induction, this article addresses three interrelated questions: What are the central tasks of mentors in promoting effective induction of novice teachers at the workplace? What do mentors need to know in order to perform these tasks? What kind of professional frameworks for learning to mentor?
I claim that in order to help novices ‘break good from experience’, as the title metaphorically suggests, mentors need to be prepared to flexibly adapt strategies from diverse mentoring models according to the particular socio-cultural features of induction of novices’ workplace and to aspects of subject matter teaching. Such kind of mentoring is, thus, attentive to discursive tensions between ideologies, rituals, values, belief systems and behaviors that surge amongst the various players involved. The article describes the central tasks for mentors of novice teachers, the knowledge-base required of mentors in order to perform these tasks and the kind of professional frameworks for learning to mentor.
Prevalencia motivacional en alumnado de Educación Secundaria Obligatoria. ¿el género y el expediente académico determinan la diferencia?
Authors: Pino-Juste Margarita Rosa , Pérez Fernández Alba , Domínguez Rodríguez Víctor 
Published: November 2021

Introducción: La evidencia científica señala que la motivación es un requisito indispensable para el aprendizaje, al permitir a los estudiantes satisfacer sus necesidades de conocimiento.
Metodología: El objetivo de este estudio es conocer los factores que predominan en la motivación del aprendizaje y como estos pueden estar influidos por el género y el expediente académico. Para ello se lleva a cabo un estudio descriptivo, inferencial y correlacional de corte transversal. Se utilizó para ello la escala de estrategias de aprendizaje y motivación (CEAM II: parte motivacional) traducida y adaptada al español por Roces, Tourón y González (1995).
Resultados: El nivel motivacional del alumnado es medio con mayor presencia en el género femenino. No se identificaron diferencias significativas a favor de las mujeres, salvo en el valor de las tareas y autoeficacia. La correlación entre factores motivacionales resultó significativa, positiva y medio-alta, excepto con el factor ansiedad que fue negativa y muy baja.
Discusión: Las implicaciones de estos resultados sugieren que el profesorado debe conocer los motivos que llevan al alumnado a satisfacer sus necesidades de conocimiento, ya que estos se puede mejorar a través de experiencias educativas apropiadas.
Percepción del alumnado del Grado de maestro de Educación Infantil y Primaria sobre las competencias transversales adquiridas durante su formación
Authors: Santana Ardila Cristina , Becerra Traver María Teresa , Sánchez Herrera Susana 
Published: November 2021

Con la llegada del Marco Europeo, la educación superior ha sufrido cambios, uno de ellos la introducción de las competencias transversales. Por ello, este trabajo pretende analizar la percepción que el alumnado de Educación Infantil y de Educación Primaria de la Universidad de Extremadura tiene con respecto a las competencias transversales adquiridas a lo largo de su formación como maestros. Para ello, partiendo de las propias competencias transversales que tienen que conseguir para la obtención de la titulación, se ha diseñado un cuestionario on-line en el que participaron 212 alumnos. Los resultados muestran que el alumnado en su gran mayoría tiene adquiridas las competencias, excepto la de lenguas extranjeras que es la que menos valoración tiene. Finalmente se extrae que el alumnado sí tiene, de forma general, adquiridas las competencias transversales, lo que supone una buena formación para los alumnos que en un futuro serán docentes.

Published: November 2021

Kurangnya keterlibatan siswa sering menjadi permasalahan dalam pembelajaran jarak jauh (PJJ). Dalam situasi tersebut, siswa membutuhkan adanya dukungan akademik. Penelitian ini bertujuan mengetahui bagaimana perspektif guru terkait keterlibatan siswa dalam PJJ serta melihat dukungan seperti apa yang diberikan guru kepada siswa dalam PJJ. Penelitian ini menggunakan pendekatan kualitatif. Subjek penelitian merupakan 23 guru SMK yang melaksanakan PJJ. Pengambilan data dilakukan menggunakan kuesioner yang berisi pertanyaan-pertanyaan terbuka mengenai pengalaman guru selama pelaksanaan PJJ. Data kemudian dianalisis menggunakan metode analisis tematik. Hasil penelitian menunjukkan bahwa guru melihat siswa kurang terlibat dalam PJJ. Selain itu, dalam PJJ ini diketahui bahwa guru masih dapat memberikan dukungan-dukungan walaupun secara fisik terpisah dengan siswa. Dukungan yang diberikan dapat berupa dukungan emosional, dukungan informasi, dukungan instrumental maupun dukungan penghargaan. The lack of student engagement often becomes the problem of distance learning. Amid this situation, students need academic supports. This research aims to investigate the perspective of teachers on student engagement and to investigate supports that the teachers give to students. This research employed a qualitative approach and thematic analysis method. Participants of this research were 23 Vocational High School teachers who implemented distance learning. Data was gathered by means of a questionnaire containing open-ended questions. Research results revealed that students have low behavioral engagement. For emotional engagement, some students showed negative feelings, but other students showed positive feelings. The same case with cognitive engagement. Although some students had low motivation, other students showed their efforts in distance learning. In addition, results showed teachers provide supports to students such as emotional support, informational support, instrumental support, and appraisal supports.

Objectives: Like other areas of care affected by the COVID-19 pandemic, telehealth (both audio and video) was rapidly adopted in the obstetric setting. We performed a retrospective analysis of electronic health record (EHR) data to characterize the sociodemographic and clinical factors associated with telehealth utilization among patients who received prenatal care.
Materials and Methods: The study period covered March 23rd, 2020 to July 2nd, 2020, during which time 2,521 patients received prenatal care at a large academic medical center. We applied a generalized logistic regression to measure the relationship between the patients’ sociodemographic factors (in terms of age, race, ethnicity, urbanization level, and insurance type), pregnancy complications (namely, type 2 diabetes, chronic hypertension, and fetal growth restriction), and telehealth usage, as documented in the EHR.
Results: During the study period, 2,521 patients had 16,516 prenatal care visits. 938 (37.2%) of the patients participated in at least one of 1,934 virtual prenatal care visits. Prenatal visits were more likely to be conducted through telehealth for patients who were older than 25 years old and lived in rural areas. In addition, patients who were with type 2 diabetes were more likely to use telehealth in their prenatal care (adjusted Odds Ratio (aOR) 7.247 [95% Confidence Interval (95% CI) 4.244 – 12.933]). By contrast, patients from racial and ethnic minority groups were less likely to have a telehealth encounter compared to white or non-Hispanic patients (aOR 0.603 [95% CI 0.465 – 0.778] and aOR 0.663 [95% CI 0.471 – 0.927], respectively). Additionally, patients who were on state-level Medicaid were less likely to use telehealth (aOR 0.495 [95% CI 0.402 – 0.608]).
Discussion: Disparities in telehealth use for prenatal care suggest further investigations into access barriers. Hispanic patients who had low English language proficiency may not willing to see doctors via virtual care. Availability of high-speed internet and/or hardware may hold these patients who were insured through state-level Medicaid back due to poverty. Future work is advised to minimize access barriers to telehealth in its implementation.
Conclusions: While telehealth expanded prenatal care access for childbearing women during the COVID-19 pandemic, this study suggested that there were non-trivial differences in the demographics of patients who utilized such settings.

Мета: систематизувати та узагальнити науково-методичні знання і результати практичного досвіду фізичної реабілітації хворих після реконструкції передньої схрещеної зв’язки при артроскопічних оперативних втручаннях. Методи: теоретичний комплексний аналіз і синтез даних науково-методичної літератури та джерел мережі Інтернет. Результати. Проаналізовано методи лікування декомпенсованої передньої нестабільності колінного суглоба, спричиненої розривом передньої схрещеної зв’язки. Весь післяопераційний реабілітаційний період перебігає на тлі етапних процесів інкорпорації трансплантату в кісткових тунелях. Саме стадійність відновлення трансплантату є основою для виділення різних періодів реабілітації. Розглянуто сучасні підходи до застосування засобів фізичної реабілітації при артроскопічних оперативних втручаннях у хворих з ушкодженням передньої схрещеної зв’язки. Висновки. Лікування таких хворих необхідно проводити з обов’язковим урахуванням анатомо-функціональних особливостей, використовувати методи раннього і повноцінного відновлення пошкоджених структур суглоба, прагнути до підбору відновлювальних операцій, що не вимагають іммобілізації суглоба. Крім цього, адекватні відновні комплекси, що враховують тип фіксації трансплантату, функціональні особливості ураженої кінцівки й інші чинники, у тому числі ступінь порушення функції колінного суглоба, розроблено далеко не для всіх випадків ушкоджень та їх наслідків. На сьогодні актуальною є розробка програм фізичної реабілітації, що враховують тип фіксації використаного трансплантату при артроскопічних оперативних втручаннях.

Published: November 2021

Sümerbank Beykoz Deri ve Kundura Fabrikasının temelini oluşturan Beykoz Miri Debbağhaneleri Sultan II. Mahmut zamanında Beykoz deresinin Boğaza döküldüğü noktada inşa edilmiştir.1810 yılında tesis edilen ve her geçen gün gelişen debbağhane, ordunun ihtiyaçlarını karşılamak üzere Harbiye Nezaretine devredilince daha da büyüyerek imparatorluğun en büyük deri üretim merkezi haline gelmiştir. Yeni kurulan bu tesisin ismi Tabakhane-i Klevhane-i Amire olarak değiştirilmiş 1826 yılına kadar ordu için palaska, çizme, kütüklük, koşu takımları gibi askeri malzemeler üretmiştir. Ayrıca Debbağhane-i Amire ’ye 1842 yılından itibaren buhar kazanı, buhar makinası, Taş Değirmen’in yanında 70 değirmen ilave edilerek tesisin makinalaşması sağlanmıştır. Harbiye Nazırı Mahmut Şevket Paşa’nın 1912 yılındaki girişimleri neticesinde Avrupa’dan getirtilen debagat makinaları sayesinde tesis yeniden modernleştirilmiştir. Beykoz Debbağhanesi ülkedeki deri üretiminde hem kapasite hem de kalite ve standart oluşturmada söz sahibi konumundadır. Zaman içerisinde büyük üretim kapasitesine erişen Beykoz Debbağhanelerinin malzeme temininde kullanılan finansman, ülke genelindeki çeşitli sancakların gelirlerinden karşılanmaktadır.
Beykoz Debbağhanesinin deri ihtiyacı büyük oranda ülkenin iç pazarlarından temin edilirken dış pazarlardan da deri getirtildiği görülmektedir. Deri tabaklamada ihtiyaç duyulan malzemelerin başında palamut gelmektedir. Ülkenin çeşitli bölgelerinden alımı yapılan palamut ve çam kabuğunun vaktinde toplanması ve hızlıca İstanbul’a ulaştırılmasına hassasiyet gösterilirdi.
Beykoz debbağhanelerinde usta ve amele olarak çalışan kişiler, üretim kapasitesine göre dönemsel olarak artıp azalmaktadır. Burada hademesinden müdürüne kadar çalışan herkes askeri personel olup disipline de çok önem verilmiştir. Beykoz Debbağhanesi üretim merkezi olmanın yanında iyi bir staj ve eğitim merkezi konumunda da olmuştur. Yeni teknikleri öğrenmek üzere öğrenci, kalfa ve ustalar gönderildiği gibi merkezden ustaların gönderilmesi de talep edilmiştir. Ayrıca bu özelliğini bir ileri düzeye taşıyarak deri sanatlarını öğreten bir de mektep kurulmuştur.
Beykoz debbağhanesi bünyesinde sosyal dayanışmayı sağlamak adına yardım sandığı kurulmuş, çalışanlara borçlar verildiği gibi maddi durumları zayıf olan ailelere de yardımlar yapılmıştır.

Authors: Nanishi Yasushi , Yamaguchi Tomohiro 
Published: November 2021

Abstract
This paper reviews the 35 years of history of plasma-excited MBE, focusing on the special value added to conventional MBE through the usage of plasma-excited molecular beams. These advantages include low-temperature surface cleaning, low-temperature growth, selective-area regrowth and impurity doping. These technologies are extremely important to realizing nanoscale low-dimensional device structures. True band gap of InN was identified only after high-quality InN became available by using plasma-excited MBE. Future prospects of this technology are also included from the device application viewpoint.
