Love, Despair, and Resiliency: Ovid’s Contributions to an Interactionist Analysis of Intimate Relations
Authors: Prus Robert
Published: December 2021

Ovid (Ovidius – Publius Ovidius Naso; 43 BCE-18 CE) is well known in classical studies and poetic circles for his insightful portrayals of heterosexual relations. However, his The Art of Love and related texts have received scant attention from those in the social sciences. Ovid’s writings on love may be best known for their advisory and entertainment motifs, but this same set of texts also provides an extended and comparatively detailed set of observations on heterosexual interchanges, as well as some remarkably astute analysis of interpersonal relations more generally. Developed within a symbolic interactionist frame (Mead 1934; Blumer 1969; Strauss 1993; Prus 1996; 1997; 1999), this paper gives particular attention to the processes by which people engage others in romantic contexts, make sense of their experiences with one another, deal with an assortment of third-parties, and manage wide ranges of related emotional sensations as they work their ways through aspects of the broader relationship process (from preliminary anticipations and initial encounters to terminations and re-involvements of relationships). It is in these respects that this paper considers the more distinctive ethnographic potential of Ovid’s depictions of love in the Roman classical era. As an instance of ethno-history, Ovid’s considerations of people’s involvements with love, sex, and romance, as well as the varying emotional states that people experience along the way, add some highly instructive cross-cultural and trans-historical dimensions to more contemporary, generic examinations of affective relationships. Using Ovid’s materials as an ethno-historical database with which to assess contemporary interactionist notions of “developing relationships,” this paper concludes with a consideration of the implications of Ovid’s works and contemporary interactionist studies for research on intimate relationships, emotionality, and influence work.
Agency and Health Policies
Authors: Lopez Barreda Rodrigo
Published: December 2021

In the current medical ethics literature, the concept of agency is receiving growing attention. Nevertheless, many of those definitions are narrow in scope. This article intends to provide a deeper understanding of this concept, allowing for its use in clinical practice and public health policies. First, it revises the current concept of agency and some of its shortcomings. Then, the article presents two philosophical accounts of agency, identifying three relevant features, namely time-extended organised planfulness, endorsement of their own actions, and identification with the activity. Lastly, the article depicts how those features may help in the application of agency to the analysis of health issues by means of a number of examples at the individual and collective levels. When analysing health issues, the health status is a key component, but the process that brought about the outcome must be examined; agency informs about this procedural dimension.
Quality of Life of Patients with Arrhythmia
Authors: Ivana Chloubová  , Alan Bulava
Published: December 2021

Introduction: Quality of life must be perceived in two levels - objective and subjective. Heart arrhythmia is a disease of the cardiovascular system that, by its subjective and objective symptoms, can affect the individual's life physically, mentally, and also socially. It can limit a person in his or her everyday activities or in activities that make them happy or satisfied.Objectives: The aim of the research was to map the quality of life of patients with arrhythmia and to verify whether the duration of arrhythmia has an effect on the quality of life of patients with arrhythmia.Methods: A standardized ASTA (Arrhythmia - Specific Questionnaire in Tachycardia and Arrhythmias) questionnaire was used to collect quantitative data. The research group consisted of adult patients diagnosed with hearth arrhythmia, hospitalized at the Department of Cardiology of the Ceske Budejovice Hospital (Nemocnice České Budějovice a.s.). A total of 127 valid questionnaires were used for data processing.Results: The research revealed that the most common symptom of arrhythmia in 58% cases was rapid heartbeat, irregular heartbeat, and a sense of heart failure. Most respondents agreed with the claim that heart rhythm disorder makes it impossible for them to perform work, study, and perform daily life activities. No statistically significant differences were found in the evaluation of the influence of the arrhythmia duration on the patients' quality of life.Conclusions: Arrhythmia duration in the selected sample does not affect the overall health status and quality of life measured by the ASTA series questionnaires. Arrhythmia restricts the patient to perform work tasks, study, and perform daily life activities.
Egészséges táplálkozással kapcsolatos szokások egyetemi hallgatók körében
Authors: Koroknay Zsuzsa , Pfau Christa
Published: December 2021

A szabadidő növekedésével párhuzamosan nőtt az emberek egészséges életmódra való törekvésével, mely különböző egészségtrendeket hozott létre. Ezen egészségtrendek az egészséges életmód két alapvető elemét érintik, a fizikai aktivitást és egészséges táplálkozást. Jelen tanulmányban a két elem közül az egészséges táplálkozást vizsgáltuk meg, annak is két szegmensét; a zöldség- és gyümölcsfogyasztást, valamint a folyadékbevitelt. A vizsgálati mintát a Debreceni Egyetem hallgatósága adta. Kutatási módszerként primer és szekunder vizsgálatot is végrehajtottunk. Szekunder kutatás esetében a nemzetközi és hazai irodalmat tekintettük át, valamint az amerikai és európai ajánlásokat hasonlítottuk össze. Primer kutatás esetében kérdőíves megkérdezés történt, mely során a hallgatók egészséges táplálkozási szokásait mértük fel. Kutatásunk során megállapításra került, hogy a felmért hallgatók mindössze 11,3%-a fogyaszt napi rendszerességgel az ajánlásoknak megfelelő zöldséget és gyümölcsöt. A folyadékfogyasztás esetében azonban kedvezőbb eredményt kaptunk. A megkérdezettek 65%-a fogyaszt legalább az ajánlásoknak megfelelő mennyiségű folyadékot.

Authors: Yeşil Pervin , Güzel Mesut
Published: December 2021

Ordu ilinde yürütülen bu çalışmada, 1990-2018 arasındaki dönemde meydana gelen arazi örtüsü/alan kullanımı değişimi CORINE arazi örtüsü veri tabanı kullanılarak incelenmiştir. Yapılan değerlendirmeler sonucunda 1990-2018 yılları arasında toplam 87.804 hektarlık alanda çeşitli değişimler meydana geldiği tespit edilmiştir. Ortaya çıkan en büyük değişim, orman ve yarı-doğal alanların, tarımsal alanlara dönüştürülmesi olup; toplam değişimin yaklaşık %77’sini oluşturmaktadır. Bu değişim sonucunda orman ve yarı-doğal alanların miktarında yaklaşık %19 oranında azalma görülmüştür. Süreç içerisinde kent dokusunu da içine alan yapay alan sınıfının büyüklüğünün %92 oranında artarak yaklaşık iki kat arttığı belirlenmiştir. Yapay alanlardaki artışın temel nedeni il ve bazı ilçelerde yaşanan hızlı kentleşme hareketleri, ormanlık alanlardaki azalışın temel nedeni ise bu alanların il halkının temel geçim kaynağı olan fındık alanlarına dönüşümü olarak yorumlanmıştır.
Cykl koniunkturalny w Turcji w latach 2005–2020 — interpretacja austriackiej szkoły ekonomii
Authors: Guzikowska Patrycja
Published: December 2021

Turkey was hit by the recession, deﬁned in a classic way (as negative real GDP growth lasting at least two quarters), three times over the discussed period. The main goal of the central bank of Turkey is to keep inﬂation as close as possible to the inﬂation target. The use of the interest rate as a tool to stabilize the economic situation is therefore limited. The country has experienced periods of high inﬂation which was not temporary, but long-term. Using the approach appropriate to the Austrian School of Economics, the article analyzes the behavior of the Turkish economy in 2005–2020. In the discussed time horizon, two phases of the business cycle have been identiﬁed according to the Austrian School of Economics — the ﬁrst from 2005 to the ﬁrst quarter of 2014, and the second from the second quarter of 2014 to 2020. It can be assumed that the Turkish economy will enter the third phase of the business cycle in the near future, although it is diﬃcult to determine when it will happen.

Authors: Chernova Elena A.
Published: December 2021

We consider current and insufficiently developed issue of social success of a special group of adolescent children with disabilities. Due to literature analysis, social success of adolescents with disabilities is an integrative personality quality, considering the psychological and pedagogical features of the development of this adolescents category, reflecting the purposeful achievement of their goals and the ability to use the achieved result for further development, contributing to successful socialization in society based on productive interaction with others. The factors contributing to the formation of social success of adolescents with disabilities that influence this process are: objective and subjective factors. The presented research results have scientific novelty and allow expanding the conceptual field of the theory of social education by clarifying the factors contributing to the formation of social success of adolescents with disabilities in the process of practicing applied activities. We determine the practical significance of the research and its results by the opportunities that open up for teachers of additional education in working with adolescents with disabilities and parents of this category of children, considering reasonable objective and subjective factors of social success formation among adolescents with disabilities in organizations of additional education.
A beszállítók technológiai heterogenitásának hatása a megrendelő vállalat rövid és hosszú távú teljesítményére
Authors: Gelei Andrea , Kenesei Zsófia
Published: December 2021

A tanulmány célja annak vizsgálata, hogy miként hat a beszállítók és a megrendelő vállalat technológiai heterogenitása az utóbbi teljesítményére. E kérdés elemzése különösen fontos napjainkban, amikor gyors, gyakran radikális, a cégek versenyképességét növekvő mértékben befolyásoló technológiai innovációkra kerül sor. A hatást a szerzők két dimenzióban tanulmányozzák: egyrészt rövid távon az üzleti teljesítmény jól ismert mutatóival, másrészt hosszú távon a dinamikus képesség koncepciója alapján. Korábbi munkák a diverz üzleti kapcsolatok teljesítménykövetkezményeit tekintve ellentmondásos eredményekről számolnak be, ezért a szerzők az azokat befolyásoló tényezőket is górcső alá veszik. Elméleti modelljüket a strukturális egyenlőségek módszerével, magyarországi vállalati mintán tesztelik, bevonva a vizsgálatba a megrendelő vállalatok ellátásilánc-menedzsmentje által tett fejlesztési erőfeszítések mediáló, illetve hálózati képességük moderáló hatását is. Eredményeik szerint a beszállítók technológiai heterogenitása indirekt módon befolyásolja a központi cég rövid távú üzleti teljesítményét és K+F-képességét a megrendelő vállalat ellátásiláncmenedzsment-fejlesztési erőfeszítésein keresztül. A moderáló hatás elemzése egyértelműen igazolta, hogy a megrendelő fejlett hálózati képessége feltétele a heterogén beszállítói portfólió biztosította pozitív teljesítményhatásnak.
Catetinho
Authors: Mennucci Marina Martins , Palazzo Pedro Paulo
Published: December 2021

Entre os monumentos da arquitetura modernista brasileira, o Catetinho, construído em 1956 próximo ao canteiro de obras de Brasília, é singular. Única obra existente de Oscar Niemeyer em madeira, que foi destinada a servir de gabinete provisório ao Presidente da República durante a construção da nova capital. Este trabalho discute o estado atual de conservação do Catetinho, como suas técnicas de projeto e construção impactam a sabedoria convencional na preservação de edifícios modernistas e de madeira, e estratégias recomendadas para proteger a integridade do material e a inteligibilidade de seu projeto original. A pesquisa aponta que, embora o sistema estrutural apressadamente detalhado seja em si um fator de risco para a durabilidade do Catetinho, os esforços de conservação podem ser auxiliados por uma visão clara de quais materiais e técnicas existentes são essenciais para a identidade do edifício.

Authors: Jeha Pecci de Oliveira Luiz , Oshiro Reynaldo Gabriela , De Castilho Maria Augusta
Published: December 2021

This work has the purpose of presenting the LAIR (Latin American Integration Route) as the achievement of diplomatic objectives already traced in the Brazilian imperial era between itself and Paraguay. This paper will show how, in the diplomatic field, the Empire can be qualified as the historical period which designed Brazil, fixing it as a regional power and positioning itself in the way of ensuring policies whose consequences would be beneficial even for its neighbors. The border relations between Brazil and Paraguay will be treated with its peculiarities, besides a description of the region’s hydrography with regards to the River Plate Basin. So, this work will enter in its historical part by analyzing the formation of the Brazilian Empire’s Second Reign, explaining its development and characteristics that interest to this paper, presenting its diplomatic conceptions, showing the problems faced by the tropical monarchy in the Platine Region and the objectives and paths searched to bypass them. In the end, it will be brought to analysis the idea of the LAIR and its Latin American integration project, with investments aiming to use the region’s hydrography to export local products, linking it with the geopolitical objective searched since imperial times to guarantee the free access to the Platine rivers. This research utilized qualitative methodology, analyzing books and articles in the area to base the central thesis. The result achieved met the original goal, showing that the LAIR comes from the development of a conception of foreign relations created, for Brazil, in the Monarchy.

Authors: Aniowati Fitri , Naim Cantika Nadrotan , Anggraeni Nova Dwi , Widyaningsih Pratiwi Nur
Published: December 2021

Background: Oral squamous cell carcinoma (OSCC) is an oral cancer with a low life expectancy, less than five years after diagnosis. The drug therapy often used for OSCC patients is cisplatin, but it is considered to cause tumour persistence, drug resistance, and high toxicity. Therefore, it is important to test the development of alternative drugs from natural ingredients. One potential ingredient is green chilli pepper (Capsicum frutescens L.). It contains capsaicin that functions as an anticancer agent by suppressing BCa tumorigenesis so that proliferation is inhibited, as well as increasing and preventing p53 antibody mutations that play a role in cancer cell apoptosis. Purpose: This study aimed to compare effectiveness using capsaicin nanoparticle gel from green chilli pepper extract levels of 1% and 3.3% to reduce OSCC nodules. Methods: This study used 20 Rattus norvegicus that were randomly divided into five groups; C- (rat without treatment), C+ (rat induced to 7,12-Dimethylbenz(a)anthracene (DMBA)), E1 (DMBA exposed and given cisplatin, E2 (rat induced to DMBA and capsaicin extract nanoparticle gel with a concentration of 1%), and E3 (rat induced to DMBA and capsaicin extract nanoparticle gel with a concentration of 3.3%). The data were analysed statistically with the one-way ANOVA and least significance difference (LSD) test. Results: The comparison of mean nodule volume between C+ (5.834 ± 2.77 mm3) with E1 (1.75 ± 0.37 mm3), E2 (1.747 ± 0.36 mm3), and E3 (1.812 ± 0.11 mm3) had a significant difference (p = 0.00, p ≤ 0.05). Conclusion: Capsaicin nanoparticle gel with green chilli pepper extract at levels of 1% (E2) reduces OSCC nodules by more than gel with green chilli pepper extract at 3.3% (E3) concentration.

Authors: Priya SR , Garg Srinjeeta , Dandekar Mitali
Published: December 2021

Intraoperative nerve monitoring (IONM) has evolved into an objective tool not only for the identification but also for the preservation and prognostication of function of the recurrent laryngeal nerve in thyroid surgeries. Technical improvements have resulted in the increasing incorporation of IONM into operating rooms around the world. The importance of adherence to recommended standards is also recognized as being vital in optimizing the efficacy of IONM. The advent of continuous IONM has made real-time nerve monitoring possible, thus providing the surgeon with an ally in difficult surgeries. Additionally, as thyroid surgeries are evolving into remote access and minimally invasive procedures, so also is the applicability of IONM. This review focuses on the use of IONM for nerve monitoring in thyroidectomies for neoplastic conditions while discussing the rationale, technique, and interpretation of findings and their implications.

Thermal treatment of silica optical fibers with CO2-laser radiation
Authors: Khotiaintsev S. , Castro-Martinez A.N.
Published: December 2021

We investigate theoretically and experimentally the effect of high-power CO2–laser radiation on silica optical fibers. We show that it takes several tens of milliseconds to heat the standard single–mode silica optical fiber to the fusing temperature of silica with the focused radiation of the CO2 laser of an output power of about 5 W. A point by point exposure of the optical fiber to the focused radiation of the CO2 laser under simultaneous axial tension results in a periodic necking of the optical fiber. Such an alteration of fiber parameters constitutes the Long Period Fiber Grating

Реферат: Проблематика. При інтенсивному моніторингу профілактичного огляду пацієнтів у медичних закладах первинної ланки найбільш зручно по ультразвуковим зображенням діагностувати лише наявність чи відсутність фіброзних змін печінки. Подібний підхід є найбільш ефективним при профілактиці захворювань, при цьому алгоритм класифікації визначає лише наявність патології, а уточнення діагнозу, ступінь ураження вже знайденої патології може визначатися в подальшому у спеціалізованих медичних закладах висококваліфікованим лікарем діагностом. Однак, розробка автоматизованих систем підтримки рішень при диференціації клінічно схожих захворювань завжди є актуальною задачею в медичній практиці. Однією з таких задач є диференціація  аутоімунного гепатиту і хвороби Вільсона.
Мета. Розробити діагностичний алгоритм класифікації аутоімунного гепатиту і хвороби Вільсона за  результатами аналізу ультразвукових зображень печінки.
Методика реалізації. Дані для виконання дослідження надано Інститутом ядерної медицини та променевої діагностики НАМН України – 9 знімків УЗД стосуються хворих на аутоімунній гепатит, 20 знімків пацієнтів з хворобою Вільсона. Об’єктами класифікації є області інтересу, що було виділено на ультразвукових зображеннях медичними фахівцями. Для збільшення об’єму навчальної вибірки та підвищення якості системи класифікації застосовано аугментацію одержаних зображень. В результаті для навчання (навчальна вибірка) та верифікації (тестова вибірка) було одержано загалом 600 областей інтересу (150 для аутоімунного гепатиту і 450 для хвороби Вільсона).  Виходячі з припущення, що відмінності у характеристиках зображень класів знаходяться у відмінностях їх текстур в роботі розраховані текстурні ознаки на основі частот зустрічаємості патернів  бінарного шаблону відтінків сірого. Для побудови класифікатора застовано алгоритм Random Forest.
Результати дослідження. Загальна вибірка з 600 областей інтересу була розбита випадковим чином на навчальну (80%) і тестову (20%). Одержано модель класифікатору алгоритмом Random Forest з показниками якості класифікації на навчальній вибірці: точність - 100%, чутливість - 1, специфічність - 1, F-score -1, та на тестовій вибірці: точність 90,8% , чутливість 0.767 , специфічність – 0,956, F-score – 0,873.
Висновки. Запропоновано ефективний підхід для вирішення задачі автоматичної диференційної діагностики аутоімунного гепатиту та хвороби Вільсона. На основі текстурних ознак та алгоритму випадкового лісу була отримана високоякісна модель класифікації

ОСОБЛИВОСТІ ФОРМУВАННЯ ТЕХНІЧНОЇ ДОКУМЕНТАЦІЇ НА МЕДИЧНІ ВИРОБИ, ЩО ІМПЛАНТУЮТЬ
Authors: Пономаренко Д.І. , Луценко Т.М. , Пашук В.В , Щоткіна Н.В.
Published: December 2021

Реферат – значні дослідження та розробки в галузі біомедичних імплантатів розширили можливості лікування широкого спектру захворювань. Імплантат є інвазивним медичним виробом, який повністю або частково вводиться в тіло або у природний отвір людини для заміни пошкоджених структур в організмі людини та залишається в організмі людини терміном не менш ніж на 30 днів. Технічна документація (технічний файл) являє собою сукупність документів, які описують медичний виріб. Технічний файл розробляється під час процесу проектування і розробки виробу, підтримується протягом усього життєвого циклу, має бути структурований та підтримувати адекватний рівень деталізації, уникаючи при цьому включення зайвих деталей, щоб полегшити огляд та оцінку. Життєвий цикл медичного виробу складається з шести етапів: концепція, планування, проектування, валідація, запуск та постмаркетинговий нагляд. Для оцінки відповідності імплантатів в українському законодавстві обов‘язковим є відповідність нормативним вимогам двох технічних регламентів: Технічного регламенту щодо медичних виробів, Технічного регламенту щодо активних медичних виробів, які імплантують і стандарту щодо медичних виробів ДСТУ EN ISO 13485:2018 Медичні вироби. Система управління якістю. Вимоги до регулювання. Для проведення процедури з оцінки відповідності імплантатів використовуються методи статистичного оцінювання зібраних даних під час проведення експертизи документації, перевірки виробництва та результатів випробувань. У даній статті проведено аналіз вимог до технічного файлу: основні розділи та особливості їх формування, а також наведено перелік основних нормативних документів, що стосуються імплантатів.

Published: December 2021

Розглянуто практичні апаратні рішення щодо виділення пульсацій тиску в манжеті, що дозволяють підвищити точність та захищеність від перешкод алгоритмів вимірювання тиску. Досліджено вплив АЧХ фільтрів виділення слабких пульсацій тиску в манжеті на форму вихідного сигналу в неінвазивних автоматичних вимірювачах артеріального тиску.

Під час розробки каналу неінвазивного вимірювання тиску для приліжкового монітору виявлено невідповідність між формою кривих пульсацій тиску в манжеті, отриманих прямою високоточною реєстрацією абсолютного тиску, з формою відповідних осциляцій. Виконано моделювання в MicroCap-12 схеми каскаду виділення пульсацій тиску, яке підтвердило, що форма і амплітудні характеристики вихідного сигналу залежить від ЧСС.

Висновки: проектування каналу виділення пульсацій тиску в манжеті рекомендується виконувати у вигляді смугового фільтру, формулюючи вимоги щодо нього у часовій області (до гладкості імпульсної перехідної функції), як більш значущі у даному разі, ніж частотні.

Equal Opportunities to Access the University in Chile? An Application with a Spatial Heckman Probit Model
Authors: Quiroz Juan Luis , Peeters Ludo , Chasco Coro , Aroca Patricio
Published: December 2021

This study contributes to the debate on accessibility of higher education in Chile, focusing on both socioeconomic and geospatial dimensions of access to university study. The central question we address in this paper is the following: Does geography (physical distance and neighborhood effects) play a significant role in determining accessibility of higher education in Chile? We use Heckman probit-type (Heckit) models to adjust for selection in the process of completing the trajectory towards higher education – that is, pre-selection, application to study at university, and ultimately admission (or denial) to a higher education institution. The results shows that the geospatial elements have a significant local effect on the student’s application and access to Chilean universities.

The disruption in healthcare attention to people with alcohol dependence, along with psychological decompensation consequence of lockdown derived from COVID-19 pandemic, could have a negative impact on people who suffers from alcohol abuse disorder. Retrospective observational study of 9,966 men aged ˃16 years registered as having diagnosis of alcohol abuse disorder in the electronic medical records (EMR) of the Aragon Regional Health Service (Spain). Of those who were not infected during the study period (9,576), clinical (Glutamate-oxaloacetate -GOT-, Glutamate pyruvate -GPT-, creatinine, glomerular filtration, systolic blood pressure -SBP-, diastolic blood pressure -DBP-, total cholesterol, LDL, HDL, triglycerides, and body mass index -BMI-), pharmacological (dose per inhabitant per day -DHD- of drugs used in addictive disorders, benzodiazepines and antidepressants) and health resource use variables (primary and specialized care) were considered. Student´s T-test for matched samples was performed. After carrying out the Levene´s test, the Student´s T-test was used to analyze the changes in clinical variables between alcohol abuse disorder patients with and without COVID-19. Only creatinine and LDL show a significant but clinically irrelevant changes just after and 6 months after the end of strict lockdown. The total number of DHDs for all drugs included in the study (except for Benzodiazepines), decreased. In the same way, the use of health services by these patients also decreased. The impact of COVID-19 among this group of patients has been moderate. The reorganization of health and social services after the declaration of the state of alarm in our country, made possible the maintenance of care for this vulnerable patients.

Published: December 2021

Concussion, also known as mild traumatic brain injury (mTBI), commonly causes transient neurocognitive symptoms, but in some cases, it causes cognitive impairment, including working memory (WM) deficit, which can be long-lasting and impede a patient’s return to work. The predictors of long-term cognitive outcomes following mTBI remain unclear because abnormality is often absent in structural imaging findings. The purpose of the study was to determine whether machine learning-based models using functional magnetic resonance imaging (fMRI) biomarkers and demographic or neuropsychological measures at baseline could effectively predict 1-year cognitive outcomes of concussion. We conducted a prospective, observational study of patients with mTBI who were compared with demographically-matched healthy controls enrolled between September 2015 to August 2020. Baseline assessments were collected within the first week of injury, and follow-ups were conducted at 6 weeks, 3 months, 6 months, and 1 year. Potential demographic, neuropsychological, and fMRI features were selected according to the significance of correlation with the estimated changes in WM ability. The support vector machine classifier was trained using these potential features and estimated changes in WM between the predefined time periods. Patients demonstrated significant cognitive recovery at the third month, followed by worsened performance after 6 months, which persisted until 1 year after concussion. Approximately half of the patients experienced prolonged cognitive impairment at 1-year follow up. Satisfactory predictions were achieved for patients whose WM function did not recover at 3 months (accuracy=87.5%), 6 months (accuracy=83.3%), 1 year (accuracy=83.3%), and performed worse at 1-year follow-up compared to baseline assessment (accuracy=83.3%). This study demonstrated the feasibility of personalized prediction for long-term postconcussive WM outcomes based on baseline fMRI and demographic features, opening a new avenue for early rehabilitation intervention in selected individuals with possible poor long-term cognitive outcomes.

The fatty acid elongase ELOngation of Very-Long-chain fatty acids protein 2 (ELOVL2) controls the elongation of polyunsaturated fatty acids (PUFA) producing precursors for omega-3, do-cosahexaenoic acid (DHA), and omega-6, docosapentaenoic acid (DPAn6) in-vivo. Expectedly, Elovl2-ablation drastically reduced the DHA and DPAn6 in liver mitochondrial membranes. Unexpectedly, however, total PUFAs levels decreased further than could be explained by Elovl2 ablation. The lipid peroxidation process was not involved in PUFAs reduction since malondial-dehyde-lysine (MDAL) and other oxidative stress biomarkers were not enhanced. The content of mitochondrial respiratory chain proteins remained unchanged. Still, membrane remodeling was associated with high voltage-dependent anion channel (VDAC) and adenine nucleotide trans-locase 2 (ANT2), a possible reflection of the increased demand on phospholipid transport to the mitochondria. Mitochondrial function was impaired despite preserved content of the respiratory chain proteins and the absence of oxidative damage. Oligomycin-insensitive oxygen consumption increased, and coefficients of respiratory control were reduced by 50%. The mitochondria became very sensitive to fatty acid-induced uncoupling and permeabilization, where ANT2 is involved. Mitochondrial volume and number of peroxisomes increased as revealed by transmission elec-tron microscopy. In conclusion, the results imply that endogenous DHA production is vital for the normal function of mouse liver mitochondria and could be relevant not only for mice but also for human metabolism.

Uncontrolled transmission of Mycobacterium tuberculosis (M. tuberculosis, MTB) drug resistant strains is a challenge to control efforts of global tuberculosis programme. Due to increasing multi-drug resistant (MDR) cases in Arunachal Pradesh, a northeastern state of India, the tracking and tracing of these resistant MTB strains is crucial for infection control and spread of drug resistance. This study aims to correlate the phenotypic DST, genomic DST (gDST) and phylogenetic analysis of MDR-MTB strains in the region. Of total 200 suspected MDR-MTB isolates, 125(62.5%) were identified as MTB. MGIT-960 SIRE DST detected 71/125(56.8%) isolates as MDR/RR-MTB of which 22(30.9%) were detected resistant to second line drugs. Whole genome sequencing of 65 isolates and their gDST found Ser315Thr mutation in katG (35/45;77.8%) and Ser531Leu mutation in rpoB (21/41;51.2%) associated with drug resistance. SNP barcoding categorized the dataset with Lineage2 (41;63.1%) being predominant followed by Lineage3 (10;15.4%), Lineage1 (8;12.3%) and Lineage4 (6;9.2%) respectively. Phylogenetic assignment by cgMLST gave insights of two Beijing sub-lineages viz; 2.2.1 (SNP difference < 19) and 2.2.1.2 (SNP difference < 9) associated with recent ongoing transmission in Arunachal Pradesh. This study provides first insight in identifying the ongoing transmission of two virulent Beijing sub-lineages associated with TB drug resistance.

Authors: Boerchi Diego , Magnano Paola
Published: December 2021

Vocational interest inventories are widely used by career counselors to help individuals to make career choices. The most common approach to assess vocational interests is based on verbal or textual stimuli. However, some of them are based on pictorials to overcome reading limits and provide additional information about the working environment and the activities related to a particular job. This article aims to present two studies on the development and first validation of the Multilingual Iconographic Professional Interest Inventory (MIPII) on two samples, one composed of 792 high-school students, and one composed of 366 middle school students. The inventory aimed to assesses the vocational interests of people over 19 areas by illustrations representing 95 jobs, five for each one, combined with their title in six different languages (Arabic, German, English, Spanish, French and Italian in this order). Both illustrations and titles are provided separately in the male and female version on the same page.

Published: December 2021

Nilai Tukar Petani Tanaman Pangan (NTPP) merupakan salah satu indikator kesejahteraan petani yang menunjukkan perbandingan kemampuan daya beli antara produk yang dibayar oleh petani untuk kebutuhan konsumsi dan input produksi dengan penerimaan petani. Walaupun sub sektor tanaman pangan masih memegang peranan penting dalam menunjang kehidupan penduduk (petani) dan menjadi sektor mayoritas yang diusahakan serta menjadi sumber penerimaan utama petani di Propinsi Sulawesi Selatan, ternyata NTPP pada sub sektor ini menempati urutan terendah dibandingkan sub sektor lainnya pada sektor pertanian di bulan Januari tahun 2020. Merujuk pada data tersebut, maka tujuan penelitian ini adalah menganalisis  pengaruh luas panen, jumlah produksi, harga jual output, pupuk & pestisida serta konsumsi rumah tangga petani terhadap NTPP di Propinsi Sulawesi Selatan. Metode yang digunakan adalah analisis regresi linear berganda dengan hasil menunjukkan bahwa variabel harga jual output dan konsumsi rumah tangga secara parsial berpengaruh signifikan dan bernilai positif terhadap perkembangan NTPP, sementara variabel luas panen, jumlah produksi, harga jual output, pupuk dan pestisida serta konsumsi rumah tangga, secara simultan mempengaruhi NTPP.

The study consists of statistical processing of the results of direct repeated measurements of soluble oxygen level, pH, temperature in the aquarium of the artificial ecosystem, analysis of errors and total standard uncertainty of measurement results, construction of a system with fuzzy logic to determine the impact of aquatic parameters on aquarium water quality. The system makes it possible to measure illuminance up to 45,000 lux, air temperature in the range from 12 to 42 0C, water temperature in the range from 15 to 28 0C, pH level from 5 to 9, dissolved oxygen level from 5 to 10 mg / l, has a proximity sensor , has the ability to turn on, if necessary, heating, water aeration, additional light sources. The measurement error on each of the channels does not exceed 2.5%. The need to create a control system arose due to the fact that there is a need to ensure the natural development of plants and fish in an artificial ecosystem that mimics the environment as close as possible to the natural one. In order for the ecosystem to perform its functions, it is necessary to timely control these parameters and respond quickly to the parameters exceeding the critical values. This task can be accomplished only by creating a control system. In order to bring people closer to the wildlife of exotic countries of the world, you can create corners of wildlife at school, enterprise, institution. An artificial ecosystem, which is a clear and versatile example of wildlife, will help students in the formation of a new culture of relationships with nature, the environment, and allow workers to relax morally by observing wildlife. Such a fruitful rest affects the recovery of people. The artificial ecosystem helps to involve children with talent in research work, in designing projects, performing works related to creativity.

The COVID-19 pandemic has affected human life at multilevel and is still a tremendous challenge for all sectors of life without exception to education. To cope  COVID-19 effects in education, online teaching and learning was adopted. This study explored how science teachers’ learning remained motivated to teach, despite all the limitations they encountered and endured during the COVID-19 pandemic. This work was carried out in developing county such as Indonesia, Rwanda, Cambodia and Paraguay. The study examines how science teachers’ in developing country have faced obstacle, and meanwhile, despite this, they are still trying their hardest to stay focused on achieving their personal goals during the pandemic. This research is geared by descriptive qualitative approach. Data were collected in series of online survey with thirty nine teachers cross the developing country.  The results showed that the science teachers’ learning with e-learning was less effective because not all teachers and parents of students understood the internet. During the COVID-19 pandemic, teachers are highly required to develop e-learning science learning that can help achieve learning goals, so that e-learning can satisfy all parties, and can reduce its negative impact. Science learning with e-learning can foster educators in mastering digital technology.
