Heart Rate Variability and Firstbeat Method for Detecting Sleep Stages in Healthy Young Adults: Feasibility Study
Authors: Kuula Liisa , Pesonen Anu-Katriina
Published: December 2020

Background

Polysomnography (PSG) is considered the only reliable way to distinguish between different sleep stages. Wearable devices provide objective markers of sleep; however, these devices often rely only on accelerometer data, which do not enable reliable sleep stage detection. The alteration between sleep stages correlates with changes in physiological measures such as heart rate variability (HRV). Utilizing HRV measures may thus increase accuracy in wearable algorithms.

Objective

We examined the validity of the Firstbeat sleep analysis method, which is based on HRV and accelerometer measurements. The Firstbeat method was compared against PSG in a sample of healthy adults. Our aim was to evaluate how well Firstbeat distinguishes sleep stages, and which stages are most accurately detected with this method.

Methods

Twenty healthy adults (mean age 24.5 years, SD 3.5, range 20-37 years; 50% women) wore a Firstbeat Bodyguard 2 measurement device and a Geneactiv actigraph, along with taking ambulatory SomnoMedics PSG measurements for two consecutive nights, resulting in 40 nights of sleep comparisons. We compared the measures of sleep onset, wake, combined stage 1 and stage 2 (light sleep), stage 3 (slow wave sleep), and rapid eye movement (REM) sleep between Firstbeat and PSG. We calculated the sensitivity, specificity, and accuracy from the 30-second epoch-by-epoch data.

Results

In detecting wake, Firstbeat yielded good specificity (0.77), and excellent sensitivity (0.95) and accuracy (0.93) against PSG. Light sleep was detected with 0.69 specificity, 0.67 sensitivity, and 0.69 accuracy. Slow wave sleep was detected with 0.91 specificity, 0.72 sensitivity, and 0.87 accuracy. REM sleep was detected with 0.92 specificity, 0.60 sensitivity, and 0.84 accuracy. There were two measures that differed significantly between Firstbeat and PSG: Firstbeat underestimated REM sleep (mean 18 minutes, P=.03) and overestimated wake time (mean 14 minutes, P<.001).

Conclusions

This study supports utilizing HRV alongside an accelerometer as a means for distinguishing sleep from wake and for identifying sleep stages. The Firstbeat method was able to detect light sleep and slow wave sleep with no statistically significant difference to PSG. Firstbeat underestimated REM sleep and overestimated wake time. This study suggests that Firstbeat is a feasible method with sufficient validity to measure nocturnal sleep stage variation.

BACKGROUND

Lack of quantifiable biomarkers is a major obstacle in making diagnosis and predicting treatment response in depression. In adolescents, increasing suicidality during antidepressant treatment further complicate the problems. Emerging healthcare systems based on digital technology are beginning to show promising results in dealing with mental health issues.

OBJECTIVE

Using Smart Healthcare System for Teens At Risk for Depression and Suicide (STAR-DS) smartphone application and machine learning, we sought to evaluate digital phenotypes which represent the diagnosis and treatment response of depression in adolescents.

METHODS

Our study included 24 adolescents (15.4±1.4 years, 17 girls) with major depressive disorder (MDD) diagnosed with K-SADS-PL and 10 healthy controls (13.8±0.6 years, 5 girls). Their depression status was evaluated using the Children’s Depression Rating Scale–Revised (CDRS-R) and CGI-S every week during the study period. After collecting the baseline data for 1 week, MDD adolescents were treated with escitalopram in an 8 week, open-label trial. Both MDD and control groups were monitored for another 4 weeks after the baseline week.

We applied deep learning approach for the analysis of data. Deep Neural Network (DNN) was employed for classification and NEural network with Weighted Fuzzy Membership functions (NEWFM) for feature selection. We extracted features from directly collected data via the mobile phone (the number and total time of calls and text messages sent or received, mobile phone usage time, movement distance, amount of activity measured by gyroscope) on a daily basis. The distance from the mean value and standard deviation of each features per week were also extracted.

RESULTS

We could predict the diagnosis of depression with training accuracy of 96.3% and 3-fold validation accuracy of 77%. Of 24 depressed adolescents, 10 responded to antidepressant treatment. Including data on medications taken by the MDD group, we predicted the treatment response of depressed adolescents with training accuracy of 94.2% and 3-fold validation accuracy of 76%.

CONCLUSIONS

The STAR-DS smartphone application demonstrated preliminary evidence of predicting diagnosis and treatment response in depressed adolescents. This is the first study to predict treatment response of MDD in adolescents, examining smartphone based objective data with machine learning approaches.

Authors: Biebl Johanna Theresia , Rykala Marzena , Strobel Maximilian , Kaur Bollinger Pawandeep , Ulm Bernhard , Kraft Eduard , Huber Stephan , Lorenz Andreas
Published: December 2020

BACKGROUND

The use of digital therapeutic solutions for rehabilitation of conditions such as osteoarthritis provides scalable access to rehabilitation. Few validated technological solutions exist to ensure supervision of users while they exercise at home. Motion Coach (Kaia Health GmbH) provides audiovisual feedback on exercise execution in real time on conventional smartphones.

OBJECTIVE

We hypothesized that the interrater agreement between physiotherapists and Motion Coach would be noninferior to physiotherapists’ interrater agreement for exercise evaluations in a cohort with osteoarthritis.

METHODS

Patients diagnosed with osteoarthritis of the knee or hip were recruited at a university hospital to perform a set of 6 exercises. Agreement between Motion Coach and 2 physiotherapists’ corrections for segments of the exercises were compared using Cohen κ and percent agreement.

RESULTS

Participants (n=24) were enrolled and evaluated. There were no significant differences between interrater agreements (Motion Coach app vs physiotherapists: percent agreement 0.828; physiotherapist 1 vs physiotherapist 2: percent agreement 0.833; P<.001). Age (70 years or under, older than 70 years), gender (male, female), or BMI (30 kg/m2 or under, greater than 30 kg/m2) subgroup analysis revealed no detectable difference in interrater agreement. There was no detectable difference in levels of interrater agreement between Motion Coach vs physiotherapists and between physiotherapists in any of the 6 exercises.

CONCLUSIONS

The results demonstrated that Motion Coach is noninferior to physiotherapist evaluations. Interrater agreement did not differ between 2 physiotherapists or between physiotherapists and the Motion Coach app. This finding was valid for all investigated exercises and subgroups. These results confirm the ability of Motion Coach to detect user form during exercise and provide valid feedback to users with musculoskeletal disorders.

Published: December 2020

Amaç: Bu çalışma örtük liderlik teorileri çerçevesinde kadınların ve erkeklerin zihinlerindeki lider ve kadın lider prototiplerini ortaya koymayı amaçlamaktadır. Kadınlar ve erkeklerin zihinlerindeki lider prototipleri ile yönetici bir kadın olduğunda lider olarak kabul görmesi için belirledikleri prototip farklılaşmakta mıdır sorusu araştırmanın temel çıkış noktasıdır.
Yöntem: Bu çalışma, çalışanların cinsiyet faktörü göz önüne alındığında lider-kadın lider özelinde örtük liderlik teorilerine ilişkin farklılıkları belirlemek amacıyla gerçekleştirilen karşılaştırmalı nicel bir araştırmadır. Çalışmanın örneklemini Sivas Cumhuriyet Üniversitesi rektörlük yerleşkesinde çalışan 307 idari personel oluşturmaktadır. Araştırmada Tabak, Kızıloğlu ve Türköz’ün (2013) Türkiye için geliştirdiği “örtük liderlik teorisi” ölçeği kullanılmıştır. Yapılan faktör analizi sonucunda lider prototipleri kişisel ahlak, beceriklilik- etkileyicilik, duyarlılık ve güç olmak üzere dört boyut altında toplanmıştır.
Bulgular: Analiz sonuçlarına göre, genel lider prototiplerine ilişkin olarak, katılımcıların cinsiyetleri açısından ortalama değerler arasında bir farklılık bulunmamıştır. Erkek ve kadın personelin, kadın yöneticilerin lider olarak kabul görmesi için bekledikleri özelliklere ilişkin tüm alt boyutlarda ortalama değerler arasında istatistiksel olarak anlamlı bir farklılık bulunmuştur. Kadın personelin bir liderden beklentileri ile yönetici bir kadın olduğunda beklentileri arasında alt boyutların hiçbirinde anlamlı bir farklılık gözlenmemiştir. Erkek personelin ise bir liderin özelliği olarak gördükleri ve kişinin lider olarak kabulü için aradıkları özellikler ile yönetici bir kadın olduğunda lider olarak kabul görmesi için önemli buldukları özellikler arasında fark bulunmuştur.
Sonuç: Araştırma sonuçlarına göre, kadın katılımcılar için bir liderin sahip olması ve kabulü için gerekli bulunan özellikler, liderin cinsiyetine göre değişmemektedir. Erkek katılımcıların zihninde ise, lider prototipi ile kadın yöneticilerin liderliğine dair prototip kişisel ahlak ve beceriklilik-etkileyicilik boyutlarında farklılaşmaktadır. Buna göre, göre kadın yöneticilere dair liderlik prototiplerinin, erkeklerin zihnindeki ideal lider özellikleri ile örtüşmediği söylenebilir.

Целью работы был анализ истории развития педиатрии по нумизматическим материалам. Отрасль исторической науки нумизматика (от лат. numisma — «монета») зародилась в XIX веке и стала тесно связанной с экономикой, политикой, культурой и правом, включает в себя тематическое изучение монет, медалей и плакет. Лучше всего историю педиатрии иллюстрируют различные формы медальерного изобразительного искусства (экзонумия или паранумизматика), а медаль стала прообразом памятной (мемориальной) монеты. В данной работе представлен каталог 116 нумизматических материалов (97 медалей, 11 плакет, 8 монет), в том числе некоторых уникальных, впервые приведенных. Имеются изображения на монетах и медалях международных общепринятых символов педиатрии — Гор-па-херда, или Гарпократа (мальчика, держащего палец руки у рта), и более поздних (пеликана, кормящего кровью из разорванной груди своих птенцов, и флорентийского запеленатого младенца). В работе по материалам нумизматики отражены этапы ­изучения использования лечебных факторов, есть ссылки на значительные исторические события, упоминаются краткие биографии медиков (46 персон), внесших неоценимый вклад в формирование педиатрической науки. На медалях можно встретить портреты организаторов службы оказания медицинской помощи детям, видных педиатров и представителей узких специальностей. К большому сожалению, пока память о знаменитых врачах-педиатрах прошлого недостаточно отмечена выпуском нумизматической продукции, поэтому в будущем надеемся на планомерный подход к этому делу, на целенаправленную пропаганду достижений педиатрии средствами нумизматики, которая подает наглядный пример для изучения истории медицины, способствует повышению уровня образованности врачей. Авторы рассчитывают на появление новых интересных материалов таких малых форм изобразительного искусства.

Роль сбалансированных растворов в практике врача
Authors: Lyzohub K.I. , Nikonov V.V. , Lyzohub M.V.
Published: December 2020

Инфузионная терапия играет главную роль в лечении больных на догоспитальном этапе, в отделениях интенсивной терапии, в периоперационном и постоперационном периоде. При расчете необходимого объема флюидной терапии учитывается много факторов: с какого раствора начать жидкостную ресусцитацию (количественный и качественный состав раствора), необходимый объем, скорость и целевые показатели, определяющие корректность проведения жидкостной ресуцитации. Сегодня не существует идеального раствора для инфузионной терапии, но есть попытки усовершенствования растворов, особенно за счет уменьшения ­осложнений. Исторически солевой раствор (0,9% хлорид натрия) является наиболее часто применяемым внутривенным раствором, однако последствия его использования существенны: нарушения функции почек, гиперхлоремический ацидоз, дилюционный ацидоз. Сбалансированные кристаллоиды стали достойной заменой физиологического раствора, главной особенностью является уменьшение осложнений при их применении, в том числе и ятрогенных, что способствует улучшению клинического состояния больных. В Украине представлен сбалансированный изоплазматический кристаллоид Плазмовен®, отвечающий требованиям идеального физиологического раствора, он является оптимальным выбором для пациентов с гиповолемией, ожоговой болезнью, панкреатитами, травмами, в пери- и постоперационном периоде.

Authors: Cherniy T.V. , Andronova I.A. , Cherniy V.I. , Gorodnik G.A. , Nazarenko K.V.
Published: December 2020

Актуальность. Актуальной проблемой интенсивной терапии является своевременное прогнозирование исхода у пациентов с тяжелой черепно-мозговой травмой (ТЧМТ). Цель исследования: у пациентов с ТЧМТ, находящихся в коматозном состоянии, выявить прогностически значимые электроэнцефалографические предикторы прогноза течения коматозного состояния: выход из комы, развитие вегетативного состояния, формирование смерти мозга. Материалы и методы. Открытое проспективное исследование по типу «случай-контроль». В исследовании принимали участие 89 пациентов с диагнозом: ТЧМТ, осложненная комой I–II cт. По результатам лечения 89 больных были разделены на три подгруппы. Первую подгруппу составили 69 пациентов, вышедшие из комы. Вторая включала 7 исследуемых больных, у которых был зафиксирован исход ТЧМТ в вегетативное состояние. В третью подгруппу вошли 13 пациентов с летальным исходом ТЧМТ, причем у 6 из них было диагностировано формирование смерти мозга. В динамике терапии проводили анализ уровня сознания по шкале комы Глазго, данных компьютерной томографии (Philips Brilliance CT), количественной электроэнцефалографии (кЭЭГ). ­Результаты. Прогностически значимыми ЭЭГ-предикторами выхода из коматозного состояния являются восстановление межполушарных когерентных связей в альфа-диапазоне ЭЭГ в отведениях Fp1-Fp2, T3-T4, C3-О2, Fp2-T3 и повышение сопряженности в диапазоне высокочастотной бета-2-активности в отведениях Fp1-Fp2. Прогностически значимым ЭЭГ-предиктором развития вегетативного состояния является падение сопряженности когерентных связей в парах центральных отведений (С3-С4) во всех диапазонах, кроме дельта-диапазона. Развитие вегетативного состояния связано с межполушарным ра­зобщением и снижением уровня взаимодействия между ретикулярной формацией верхнестволового уровня и системой неспецифической регуляции ЦНС на диэнцефальном уровне. Резкое падение показателей когерентности в лобно-височных областях коры Fp1-T4, Fp2-T3 — показатель разрыва прямых и обратных когерентных связей, первый признак распада нервной системы. Выводы. Применение количественной ЭЭГ позволяет выявить прогностически значимые ЭЭГ-предикторы прогноза течения коматозного состояния: выход из комы, развитие вегетативного состояния, формирование смерти мозга.
Анализ периоперационного ведения пациентов с сопутствующей сердечно-сосудистой патологией при некардиальных операционных вмешательствах
Authors: Harbar M.O. , Fesenko U.A. , Pidhirnyі Ya.M. , Svitlyk Y.O. , Svitlyk H.V.
Published: December 2020

Актуальность. Хорошо спланированная и обоснованная дооперационная подготовка является важным инструментом снижения риска периоперационных осложнений. Европейским обществом кардиологов (ESC, 2014) и Европейским обществом анестезиологов (ESA, 2018) опубликованы рекомендации по подготовке пациента с сопутствующей кардиальной патологией к некардиальным операционным вмешательствам. Однако в нашу клиническую практику данные рекомендации имплементированы недостаточно. Целью нашей работы было проанализировать рутинную дооперационную подготовку пациента и выявить моменты, которые можно приблизить к рекомендованным стандартам с целью снижения периоперационных сердечно-сосудистых осложнений. Материалы и методы. Мы проанализировали 242 истории болезни пациентов, поступивших на плановое стационарное хирургическое лечение. Была проанализирована дооперационная подготовка с учетом клинических кардиальных факторов риска и факторов риска оперативного вмешательства. Результаты. Пациентам проведены стандартные обследования согласно установленным правилам. У всех пациентов зарегистрированы показатели электрокардиограммы, 47 % больным проведена эхокардиография покоя, 3 % выполнен тропониновый тест. С учетом интерполяции рекомендаций ESC и ESA на нашу выборку определение функциональной способности было целесообразным у 167 человек (69 %) с последующими оценкой клинических кардиальных факторов риска и определением необходимости проведения неинвазивных стресс-тестов лицам высокого риска возникновения инфаркта мио­карда и сердечной смерти. Кардиальные биомаркеры было целесообразно определить у 44 пациентов (18 %), регистрировать показатели электрокардиограммы покоя — у 127 пациентов (53 %), а эхокардиографии покоя — у 38 лиц (16 %). Такая тактика требует налаживания коммуникации между амбулаторным и стационарным звеньями медицинской системы. Выводы. Дооперационная подготовка большинства пациентов происходит в течение 24–48 часов после госпитализации в хирургическое отделение. Мы не используем определение функциональной способности пациента, не применяем шкалы оценки риска, не проводим неинвазивные стресс-тесты, недостаточно определяем кардиальные биомаркеры. Однако чаще проводим рутинные обследования, которые не являются решающими в данной клинической ситуации. В современных условиях наши клиники имеют достаточно ресурсов для внедрения рекомендаций ESC и ESA в клиническую практику.

Authors: Wimbarti Supra , Yappy Willy Kristianto
Published: December 2020

The purpose of this research was two folds: (1) to establish the face recognition software; and (2) to differentiate the ability in face recognition between Autism Spectrum Disorder (ASD) from typical adolescents. The subjects were adolescents between 10-16 years old. The experimental group consisted of 31 adolescents with ASD, the control group consisted of 32 typical adolescents. Research was done using experimental method, with face recognition software. Data collected were the number of correct faces recognized and the time needed to recognize and touch the face. The hypothesis was adolescents with ASD have worse face recognition ability compared to typical adolescents. Result showed that there were differences between ASD group compared to normal group both in the number of correct face recognitions and the time needed to choose a face with a finger touch. A one-way MANOVA revealed a significant multivariate main effect for type of groups toward the number of correct answers and time needed to answer, Wilks’ λ = 0.739, F (2,60) = 10.610, p < 0.001. The univariate main effect were also examined, whereupon significant univariate main effect for type of groups were obtained for both the amount of correct answer, F (1,61) = 15.468 p < 0.001, and the amount of time needed to answer, F (1,61) = 21.360 p < 0.001.
COMMODIFICATION OF VALUES IN AMERICAN POPULAR FAMILY MOVIES IN 1990S
Authors: Harsia Siti , Adi Ida Rochani
Published: December 2020

This thesis investigates the American popular family films from the 1950s to the 2000s by using Interdisciplinary approach. This approach is intended to explore the object of research from the history, sociology, and cultural background. The theory of representation and commodification are used together to examine how the films represent American family life and how the film industry commercializes American family values. By focusing on family roles that include the division of roles between husband and wife, interactions between family members, and the values adopted by children as a result of parenting practice, it was found that the family concept shown in films from the 1950s to the 2000s represented the reality of the dynamics of family life in every decade. Besides, in popular films of the 1990s, 'Hollywood Family Entertainment' commercialized the patriarchal issues contained in the 'traditional family' concept. There is an ideology of 'ideal woman' strictly as a housewife which was commodified through these films. Optimistic value in the family was also commodified through the child character consistently, shown by the emergence of child character who tends to be positive towards the future, focus on goals, strives for success and happiness and free in making choices.

Published: December 2020

This study aims to determine the changes of American Jews social status from the ‘other’ to the white ethnic. Social Identity theory is used in order to breakdown how the American Jews were perceived. The classification as a white ethnic, while it has its benefits, does not automatically put the American Jews and the WASP in the exact same position. Rather, the American Jews managed to stay within their ethnic boundaries while enjoying the white privilege.

Published: December 2020

This research discusses the stereotypes of LGBT in the United States, which appear on American online news. This research works under Post-Nationalist American Studies by applying the gender socialization approach and stereotype theory. Qualitative research aims to seek the differences of stereotypes experienced by LGBT in the United States. The online news portals selected include The New York Times, Washington Post, and USA Today. These news portals are chosen due to their neutrality and trustworthiness as online news portals for American society. By examining the data, the researcher found that the stereotypes experienced by Lesbian, Gay, Bisexual, and Transgender in the United States are different from one another. The findings and discussion show that Transgender stereotypes in the United States are more negative rather than others. In short, LGBT is mostly considered as a unity; however, it faces different challenges due to their minority status in the middle of American society.

Authors: C.S.T Maria Elfrieda , Adi Ida Rochani
Published: December 2020

In 2017 and 2018, Hispanic music reaches high popularity as world music. The reaction came from the American music industry, seen through the production of Hispanic music in American music industry, which brings Hispanic music as a part of American popular music. In this case, American popular musicians started to produce music that contains Hispanic music characteristics. Among all of the characteristics, the form of sensuality becomes a significant aspect in producing Hispanic music, even in American music industry. In relation to this fact, this research is conducted in order to see how the form of sensuality supports the popularity of Hispanic music. The theory of Discourse Analysis by Michel Foucault is applied to analyze sensuality as adiscourse behind the popularity of Hispanic music. As a research conducted within the frame of American Studies, this research also usesthe postmodern approach to see the new formula related to the form of sensuality in Hispanic music, especially when produced in the American music industry.

Authors: Legnani Claudio , Borgo Enrico , Macchi Vittorio , Ventura Alberto
Published: December 2020

Aim:
To compare the outcomes of patients who underwent autograft tenodesis with those who underwent allograft tenodesis for the treatment of chronic mechanical ankle instability.
Patients & methods:
Ten patients who underwent allograft lateral tenodesis were compared with 15 patients who underwent lateral tenodesis using a split peroneus brevis tendon. Patients were followed up after an average time of 10.5 years.
Results:
No statistically significant differences concerning American Orthopaedic Foot and Ankle Society and Karlsson–Peterson scores were reported (p = n.s.). A reduced average radiographic anterior talar translation was observed in the autograft group compared with the allograft group (1.4 and 4.0 mm respectively, p < 0.001).
Conclusion:
Both surgical techniques significantly improved subjective and objective outcomes in patients suffering from chronic ankle instability compared with pre-operatory status. Autograft stabilization provided reduced post-operative anterior talar translation compared with allograft tenodesis.
Intention to recommend products in virtual communities: A moderated mediation analysis
Authors: Zhang Liping , Zhu Zuping
Published: December 2020

Users' product recommendations in virtual communities (VCs) play an important role in social commerce, that is, e-commerce activities and transactions made via the social media environment. We proposed a moderated mediation model based on social exchange theory, to explore the role
of effects of belonging to VCs, guanxi capital, and trust propensity on users' intention to recommend products in VCs. We tested the model with 317 members of WeChat groups in China. The results show that guanxi capital positively mediated the link between sense of belonging and intention
to recommend. Further, the relationships between sense of belonging and guanxi capital, guanxi capital and intention to recommend, and sense of belonging and intention to recommend were all significantly moderated by trust propensity. Our findings provide insight into users' decision-making
process when recommending products in VCs, and have implications for social commerce managers promoting products in VCs.

Published: December 2020

The concept of “mass culture” and its content are becoming the subject of reflection of philosophers, religious scholars, culturologists and sociologists. Taking into account the fact that mass culture is a specific type of spiritual production, one of its main features is the possibility of widespread replication of the product. Popular culture is extremely dynamic, influencing the basic feelings of the consumer, it can generate new cultural constants that change the norms and values that have developed over centuries. The constituent elements of mass culture are usually called the media, cinema, music, literature, visual arts, sports. However, recently, a computer game has become one of the basic elements of mass culture. It was computer games that brought specific images and unexpected, sometimes paradoxical, options for rethinking the previous cultural heritage into modern mass culture. In this article, the authors, using the example of a religious and philosophical analysis of the image of the main protagonist of the series of games “God of War”, will show that behind the seeming straightforwardness and simplicity of the Spartan Kratos, there is a detailed study of his personality and history of his life. Philosophical and religious content is in many ways a decisive factor that ensured the immense popularity of Kratos in the modern gaming culture with millions of users around the world.
SAKHALYAN-BLAGOVESHCHENSK: LIFE OF THE RUSSIAN ORTHODOX COMMUNITY IN THE BORDER TERRITORIES IN THE 1920S AND 1940S (BASED ON THE MATERIALS OF EMIGRATION JOURNALISM)
Authors:   ANNA A. ZABIYAKO Amur State University, ZABIYAKO ANNA A. , ZINENKO YANA V. ,   YANA V. ZINENKO Amur State University
Published: December 2020

The publication presents a collection of archival materials about the life of the Orthodox community of Russian emigrants in Sakhalyan (today's Heihe) in the 1920s and 1940s. The publications of Harbin correspondents record the stages of the formation of the Russian enclave on the territory of the Manchu border town, allow us to correlate Russian life in Sakhalyan with the events of anti-religious policy in Soviet Blagoveshchensk, with socio-cultural, ethnocultural and ethno-religious processes in the life of the Russian emigration in the whole of Northern Manchuria. The sources of the collection were publications of a very different orientation - daily news (“Zarya”), popular literary and artistic journals (“Rubezh”), politically engaged papers (“Our Way”, “Ray of Asia”). The interest in the life of the Orthodox community in Sakhalyan, recorded in the refugee press of those years, testifies not only to the political significance of the border territories in the understanding of well-known emigre circles and the Japanese administration...
RELIGIOUS AND SYNCRETIC FOUNDATIONS OF THE MENTALITY OF RUSSIAN EMIGRANTS (ON THE EXAMPLE OF LITERARY AND ETHNOGRAPHIC PROSE BY N.A. BAIKOV AND P.V. SHKURKIN)
Authors:   Evgeniya A. Kontaleva  Amur State University, KONTALEVA EVGENIYA A.
Published: December 2020

The article reveals the phenomenon of frontier mentality and its syncretic features and marginal character. Being the birth of the border (frontier), this type of mentality is a complex construct, a specific ideological and psychological formation, the problems of which, on the one hand, are determined by social, geographical, historical and other factors, and on the other hand, are exposed to the external environment and embedded in various spheres of human existence. Among Russian emigrants who were carriers of the Russian logocentric culture, creativity becomes one of the main such spheres, especially literary one. Through the word, not only individual personality features of the authors were recorded, but also common tendencies of frontier mentality and the mentality of this historical period. The author, using the example of literary ethnography, makes an attempt to distinguish these features and the main trends in the mentality of Russian emigrants in China.

The article reveals the current situation around religious courts, arbitrations and mediation institutions in the states of North America, analyzes their structure, main functions and activities. Catholic and Orthodox church courts, courts and mediation institutions in Protestant churches and denominations, rabbinical and Sharia courts, conflict resolution bodies of Buddhists, Hindus, Mormons, Scientologists are active in the United States. Generally, US authorities do not interfere in their activities if there are no violations of the rights and freedoms of citizens, but sometimes at the state level (Arizona, Wyoming, Indiana, Oklahoma, Tennessee, Texas) the use of religious norms in arbitration courts is prohibited. A similar situation has occurred in Canada, where official religious courts operate legally, but in the provinces of Ontario and Quebec the activity of religious courts in the field of family relations was limited (in many respects due to fears of the formation of a parallel “Sharia justice”) The opinions of North American researchers on this issue are divided: some consider the activities of religious courts as a violation of the principle of secularism and think it necessary to ban their activities, others regard them as the realization of religious freedoms and advocate their preservation in the legislative framework...
Variabilidad del fruto en el ecotipo ají “charapita” (Capsicum frutescens L.) de la Amazonía peruana
Authors: Iglesias Cruz Abner Celio
Published: December 2020

El ají amazónico, conocido como “charapita” (Capsicum frutescens L.), tiene gran demanda en el mercado nacional e internacional para uso en gastronomía y salud, debido a características únicas de sabor, aroma, picor y contenido de vitamina C. Sin embargo, en mercados locales y centros de producción se observa variabilidad del fruto que origina confusión en el público consumidor, y podría afectar la calidad y la demanda. El presente trabajo tiene como objetivo mostrar la variabilidad del fruto en el ecotipo ají “charapita” que se comercializa en mercados locales de San Martin y Huánuco, en la Amazonía peruana. Para ello, luego de colectar frutos de estos lugares, se extrajeron semillas y se sembraron en bolsas pequeñas, para después plantarlas dentro de una casa de malla. Luego del análisis morfológico, se identificaron diez colecciones que presentaban variabilidad del fruto en tres características cualitativas: forma (casi redonda, seis; casi achatada, cuatro), color en estado inmaduro (verde claro, seis y verde oscuro, cuatro), color en estado maduro (amarillo-naranja, ocho y rojo, dos); y, cinco cuantitativas: peso (0,517–1,924 g), longitud (6,68-13,32 mm), diámetro (10,33-17,17 mm), número de semillas (16,22-32,72) y peso de mil semillas (2,66-3,81 g). Los datos muestran variabilidad del fruto en ají amazónico “charapita”.

La educación ambiental cumple un rol importante, a nivel del sistema educativo o a nivel de la sociedad en general, en la formación de una ciudadanía ambientalmente responsable y una sociedad peruana sostenible. Bajo esa premisa, el objetivo de la presente investigación fue determinar la relación que existe entre la educación ambiental y el manejo de residuos sólidos en la institución Educativa Carlos Fermín Fitzcarrald de Madre de Dios, Perú. El enfoque fue cuantitativo, el diseño no experimental y el tipo descriptivo correlacional de corte transversal. La muestra fue conformada por 195 estudiantes a quienes se les aplicó el Cuestionario de Educación Ambiental y el Cuestionario de Manejo de Residuos Sólidos, instrumentos con adecuados niveles de confiabilidad y validez. Los resultados permitieron identificar que, según la percepción de los estudiantes, la educación ambiental es medianamente adecuada, el manejo de residuos sólidos es poco adecuado y se determinó que el coeficiente de correlación rho de Spearman entre ambas variables fue de 0,519 con un p-valor inferior al nivel de significancia (p<0,05). Finalmente, se concluyó que existe una relación directa y estadísticamente significativa entre la educación ambiental y el manejo de residuos sólidos.
AS SUBJETIVIDADES DO AGIR SOCIOAMBIENTAL NO ATUAL CENÁRIO POLÍTICO BRASILEIRO
Authors: Alves Daniel Cardoso
Published: December 2020

Este artigo tem como objetivo apresentar uma reflexão sobre o modelo de desenvolvimento historicamente eleito e culturalmente moldado pela sociedade brasileira, cujas atividades humanas revelam-se incompatíveis com as necessidades sociais de comunidades locais e com a dinâmica dos ecossistemas, inserindo a causa socioambiental em posição secundária na hierarquia dos interesses políticos e econômicos. A questão central que o permeia é a seguinte: Quais os impactos das atuais declarações do presidente brasileiro em termos de participação social e apropriação cultural do meio ambiente no Brasil? Para tanto, adota uma abordagem qualitativa (BOGDAN; BIKLEN, 1994) e se constitui como uma revisão de literatura, por meio da qual são consultados artigos, dissertações, teses, capítulos, livros e outras fontes que tratam da temática em estudo, o que subsidiará as reflexões posteriores. Com as considerações finais, concluímos entendendo que a humanidade, ao longo dos tempos, vive um paradoxo sócio, político, econômico e ambiental que se traduz na concepção incompatível de progresso com a causa socioambiental. Com isso, os problemas ambientais são agravados, em meio aos discursos políticos por vezes de cunho puramente ideológico, ora fundados (re)apropriação social da natureza, ora na racionalidade econômica.
Palavras-chave: Participação social. Apropriação cultural. Causa socioambiental. Discursos políticos.

Published: December 2020

Este artigo busca, por meio da pandemia de Covid-19, compreender por uma leitura geográfica qual elemento melhor se aplica na explicação das diferenciações patológicas. Visto o histórico epidêmico/pandêmico da sociedade ocidental-moderna, cenários patológicos não são novidades para os homens e mulheres. Contudo, mesmo que as principais doenças que atingiram a humanidade se enquadrem em um perfil geográfico-epidemiológico semelhante, o raio de ação que cada uma adquire parece influenciar na reverberação política, social, cultural e etc.

Published: December 2020

This preliminary investigation studied the effect of circular turbulator vortex generator on heat transfer rate and pressure drop in a circular channel countercurrent double pipe heat exchanger with water working fluid. Increasing the number of circular turbulator yielded increasing heat transfer rate and pressure drop. The problem generated when increased pressure drop occurred in relation to more energy consumption of the water pumping system. Therefore, optimization in circular turbulator number is necessary to minimize the pressure drop about distance length between circular turbulator, tube diameter and thickness, type of material and crystal lattice, as well as the geometrical shape of fluid passage (circular or square). This study applied PVC outer tube and copper alloy inner tube, as well as fiberglass circular turbulator. The optimum results showed that seven parts of circular turbulator increasing heat transfer rate by 30% and pressure drop by 80% compared to that passage in the absence of circular turbulator at cool water debit of 7 L/min.

Steel that has been aluminized said as hot dipping aluminizing has better protection against corrosion and can protect against temperatures as high as 800°C. In hot dipping aluminizing, Steel is immersed into a molten aluminium for certain dipping time. The research aims to know the effect of preheating and dipping time on the toughness of low carbon steel. The method research was started by cutting the low carbon steel plate, according to ASTM E23 (Charpy test sample) into 16 pieces samples. Then the samples were grouped into four groups. Group-1 was initial samples. The Group-2 was directly immersed into molten aluminum 700 0C, for dipping time 5 minutes. The Group-3 was preheated at 700 oC for 30 minutes and then to be aluminized (700 oC) for dipping time 5 minutes. The Group-4 was preheated at 700 oC for 30 minutes and then to be aluminized (700 oC) for dipping time 10 minutes. Finally, all groups were tested by the Charpy test at room temperature. The results show that the aluminizing increases the toughness of low carbon steel from 228.125 KJ/m2 to 312.5 KJ/m2. The preheating process before aluminizing increases sharply the toughness of low carbon steel from 228.125 KJ/m2 to 512.5 KJ/m2. The increasing dipping time from 5-minute to 10-minute increase gradually the toughness from 512.5 KJ/m2 to 556.25 KJ/m2.
Estados federativos, cortes supremas e dívidas estaduais: um estudo do efeito de decisões recentes do STF sobre a credibilidade das medidas de ajuste fiscal implementadas ao longo da década de 1990
Authors: Bastos Fernando Bertoletti
Published: December 2020

Alguns anos atrás, muitos supunham que, ainda que no passado a União tivesse socorrido Estados endividados mais de uma vez, após ter aprovado um marco legal mais rigoroso em matéria fiscal que proíbe, em regra, operações de crédito entre entes federativos, o Brasil havia finalmente controlado os problemas sistemáticos da indisciplina fiscal e do endividamento em nível estadual. Nos últimos anos, no entanto, observam-se indícios muito claros de que tais problemas voltaram a se manifestar no país. Nessas circunstâncias, alguns Estados acudiram ao Supremo Tribunal Federal na tentativa de não serem penalizados pelo inadimplemento dos contratos decorrentes dessas operações de resgate ou pelo descumprimento de disposições previstas na legislação fiscal, tendo obtido decisões favoráveis em alguns casos. Tais decisões foram criticadas por órgãos ligados ao Poder Executivo federal por terem, basicamente, flexibilizado os incentivos previstos tanto nos contratos como na legislação para que os Estados mantivessem um comportamento disciplinado em matéria fiscal. O presente estudo propõe-se a examinar, com base em um ramo da literatura sobre federalismo fiscal, que se ocupa das relações entre a credibilidade do compromisso da União de não socorrer Estados endividados, de um lado, e a disciplina fiscal de Estados, de outro, o efeito de algumas decisões do STF em tais questões sobre os desdobramentos da crise das dívidas estaduais no Brasil, pondo à prova tal crítica.
