Published: January 2021

Vegetation height is an important parameter in monitoring peatlands. Vegetation height can be estimated using remote sensing. Vegetation height can be estimated by utilizing DSM and DTM. The data that can be used are LiDAR, X-SAR, and SRTM C. In this study, LiDAR data is used for DSM2018 and DTM2018 extraction. The purpose of this research is to detect the vegetation height in Central Kalimantan peatlands using remote sensing technology. The research location is in Bakengbongkei, Kalampangan, Central Kalimantan. The integration of X-SAR and SRTM C is used for DSM2000 and DTM2000 extraction. DSM2000, DTM2000, DSM2018, and DTM2018 performed height error correction with tolerance of 1.96? (95%). Then do the geoid undulation correction to EGM2008. The results obtained are DSM and DTM with a similar height reference field. If it meets these conditions it can be calculated the vegetation height estimation. Vegetation height can be obtained using the Differential DEM method. The Changing in vegetation height from 2000 to 2018 can be estimated from the difference in vegetation height from 2000 to vegetation height in 2018. Results of spatial information on vegetation height and its changes need to be tested for the accuracy. This accuracy-test includes a cross section test, height difference test, and comparison with measurements of vegetation height in the field. The results of this research can be used to monitor the changing the vegetation height in peatlands.

Published: January 2021

This study examines the role of trading volume in the crude palm oil (CPO)futures market as a proxy for information áow from the perspective of the mixture-of-distributions hypothesis (MDH). Using the data from January 2000 to April 2017, a sym-metric GARCH model has been estimated, in which the residuals follow alternatively thenormal Student-t and generalised error distribution. An alternative augmented model thatconsists of trading volume as an exogenous variable is estimated with the same error dis-tributions. Our results suggest several conclusions: First, the trading volume could not actas a true proxy for information áow. This indicates that volume of futures trading containsrelatively less price-sensitive information. Secondly, the inclusion of trading volume into theconditional variance equation with Student-t distributed errors is important for modellingpurposes when the returns are leptokurtic and positively skewed. Hence, it can be concludedthat the use of return and trading volume will enhance the current information set usedby practitioners and analysts in pricing the CPO futures contract when there exists a highdegree of leptokurtosis in the returns. This is the Örst study that validates the MDH in thecontext of the CPO futures market

Rozwój Internetu zapoczątkował erę „natychmiastowej informacji”. Dzięki technice komputerowej wymiana informacji i poglądów dokonuje się bardzo szybko a Internet stał się bardzo ważnym źródłem informacji. Możliwości, które stwarza Internet stały elementem wspomagającym proces nauczanie – uczenie się. Ta sytuacja generuje konieczność wprowadzania zmian w doborze metod dydaktycznych. W szczególności przełożenia akcentów z nauczania na uczenie się, które staje się jedynym sposobem nadążania za szybko zmieniającą się rzeczywistością. W niniejszym opracowaniu proponuje się zastosowanie w procesie edukacji na poziomie szkoły podstawowej, metody WebQuest. Opracowano ją w oparciu o teorię konstruktywizmu. Umożliwia ona rozwój umiejętności uczenia się problemowego, a także krytycznego i twórczego myślenia oraz współpracy w zespole. Idea tej metody zakłada pracę z komputerem, determinując aktywność ucznia. Sprawdza się zatem w nauczaniu zdalnym.

Celem artykułu jest zaprezentowanie nowych założeń i koncepcji kształcenia w zakresie geografii, a w szczególności treści turystycznych oraz wynikających z nich możliwości wykorzystania metody WebQuestu w szkole podstawowej. Artykuł ten ma na celu przybliżyć jej strukturę, zasady tworzenia, wskazać jej zalety oraz zachęcić do stosowania jej w praktyce w nauczaniu treści turystycznych na lekcjach geografii.

Feminizacja zawodu nauczycielskiego jest procesem postępującym na całym świecie. Przybiera on różne tempo i charakter, ujawniając tym samym swoiste oblicza, pozwalające na wydzielenie w nim konkretnych etapów. Artykuł zawiera propozycję rozpatrywania feminizacji jako procesu fazowego. Bazuje ona na wartościach bezwzględnych liczby nauczycieli obu płci i wartościach względnych, tj. odsetkach kobiet i mężczyzn w populacji nauczycielskiej oraz na relacjach między nimi, zachodzących w ujęciach dynamicznych. W toku badań stwierdzono przydatność zaproponowanego ujęcia fazowego do analiz tempa i charakteru typizacji zawodowej nauczycieli. Analiza zgromadzonych danych pozwala stwierdzić, że proces feminizacji zawodu nauczyciela w krajach europejskich w latach 2005–2017 przebiegał zarówno w sposób bardziej dynamiczny, przechodząc dwie lub trzy fazy w tym dwunastoletnim okresie. Jego charakter był mniej zróżnicowany i obejmował jedną fazę typizacji tego zawodu.
Pedagogical features of the formation of civic identity among pupils of cadet corps
Authors: Khoronko Liubov , Tskvitariya Tatyana , Akhanov Igor
Published: January 2021

The article examines the problems of cadet education, which have found their justification in the views of modern scientists, including representatives of the psychological and pedagogical direction. The analysis of works of modern authors related to the formation of civic identity is carried out. The analysis showed the features of the axiological foundations of the formation of civic identity among cadets in the modern system of Russian education. It also presents an analysis of the identified values on the problem of the formation of civil identity among cadets in the conditions of modern civil society. The phenomenon of the formation of civic identity is considered as an element of the culture of citizenship, or civic culture. Various positions of the authors on the pedagogical features of the formation of civic identity among pupils of cadet corps are presented as the identity of the individual with the status of a citizen, the willingness and ability to fulfill the duties associated with the availability of citizenship, enjoy rights, and take an active part in the life of the state. Proceeding from the axiological foundations of the formation of a person's civic identity, the authors propose to investigate the level of formation of life-meaning orientations through an analysis of the combination of terminal and instrumental values. The article presents the results that show the importance of the formation of cadets' civic identity as a result of the process of correlating oneself with the civic community, its values and norms, which brings the students of cadet corps to the awareness of their identity on the basis of understanding the rights and responsibilities realized in the process of participation in the life of society.

While Indiana University School of Medicine has had multiple regional campuses delivering the pre-clerkship phase of the education for 50 years, since 2008, all four years of medical education, including clinical, have also been available at the eight regional campuses statewide. While 67 percent of admitted students designate a preference for the Indianapolis main campus, 60 percent of students are assigned to a regional campus for pre-clerkship education. Of those, 32 percent chose to be at their assigned campus. Students are often not able to identify a compelling reason to choose a regional campus. Despite data to the contrary, including our own, a majority of students continue to believe the path to success is through the main campus in Indianapolis, and as a result, transfer to the main campus for clerkships.

In 2019, the school launched a Scholarly Concentrations Program as a key strategy to address this problem. The program leverages the unique expertise and resources at its diverse campuses and shines a spotlight on them to attract and retain students at regional campuses through educational enhancement and engaged community scholarship.

While still in pilot phase, significant progress has been realized. With faculty statewide, 11 concentrations launched in less than one year; 17 in two years. About 220 students are enrolled in concentrations statewide; about half at regional campuses. A special program through the admissions process resulted in 9 percent of the Class of 2024, with an average GPA of 3.8 and 512 MCAT, choosing to enroll at a regional campus and its associated scholarly concentration.

Immediate plans revolve around supporting concentration growth, building systems and processes to support a sustainable program, and monitoring results of the three pilot phases to inform future development and implementation. In addition, students are being recruited to regional campuses through an Early Decision Program.
Creating a Healthcare Entrepreneurship Teaching Program for Medical Students
Authors: Ahrari Aida , Sandhu Pawandeep , Morra Dante , McClennan Sarah , Freeland Alison
Published: January 2021

Introduction: The future of healthcare hinges on effective adoption of innovative solutions. Arguably, physicians are ideally positioned to propel clinical innovation given their firsthand experience with healthcare challenges; however, physicians often lack the necessary skills in innovation development and implementation methodology. The gap is partly a result of the paucity of exposure to innovation and entrepreneurship concepts within medical education and postgraduate training. To address this gap, the University of Toronto’s distributed medical education campus in Mississauga created a novel teaching initiative designed to impart themes of healthcare entrepreneurship to early stage medical learners. Methods: To inform the design of the program, the authors conducted a series of semi-structured interviews with key stakeholders, including physician entrepreneurs, innovation leaders, curriculum specialists and medical students. Using thematic analysis, key recommendations were extracted regarding learning objectives, approach to program delivery, and anticipated outcomes. A well-established entrepreneurial teaching model, the MaRS Entrepreneurship Framework, was adapted to frame the curricular content to the needs of medical learners. The resulting educational product consisted of six sessions, taught by subject matter experts, which outlined a methodological approach to the development of a medical start-up as a means of launching an innovation. Results: From November 2019 to May 2020, six sessions were held with a total of 37 unique attendees. The authors found that the series generated interest in entrepreneurship among medical students while fostering an appreciation for the basic principles of entrepreneurship. Conclusion: The next stage involves further program evaluation to guide the next iteration of the program. Potential avenues for growth include delivering the series virtually to support greater student accessibility. Future considerations include incorporating entrepreneurship into core undergraduate medical curricula and creating a dual degree program in medicine and entrepreneurship that cater to students with a deep interested in the field of healthcare entrepreneurship.

Authors: Lakshmi M  , Nandagopal S
Published: January 2021

To evaluate the leaf volatile constituents of essential oil of Coleus zeylanicus and evaluate their anti-oxidant and anti-fungal activity. The Chemical composition of Coleus zeylanicus essential oil was determined using GC-MS and FT-IR analytical techniques. The antioxidant activity was evaluated using DPPH scavenging assay. The anti-fungal effect was tested against two potential pathogenic fungal strains - Candida albicans and Malassezia furfur using agar well diffusion method. The essential oil was profiled by the presence of sesquiterpene hydrocarbons 90.67% of their total composition followed by oxygenated monoterpenes and monoterpene hydrocarbons as 5.3% and 2.1% respectively. The GC-MS results showed 14 compounds from Coleus zeylanicus leaf EO representing 98.07% of the total oil composition. The major component was identified as a-Gurjunene (35.94%), a-bisabolol (10.82%) and G-selinene (4.26%). EO showed remarkable antioxidant activity values of IC50 = 59.78± 3.21µg/ml by DPPH scavenging assay. The essential oil showed interesting anti-fungal effects against two pathogenic fungal strains. The most sensible strains to Coleus zeylanicus EO was Malassezia furfur (32.00±0.50mm) compared to that of Candida albicans (15.00±1.25mm). Hence, Coleus zeylanicus EO has potential application against fungal infection and oxidative stress-related diseases. However, further investigations are necessary to isolate and investigate the action mechanism of these bioactive compounds.

Cowpea (Vigna unguiculata) is used in West Africa for both human consumption and animal feeding. Despite its importance, the production of the crop is hampered by biotic and abiotic constraints. To overcome these constraints, the Senegalese Institute of Agricultural Research (ISRA) has set up a breeding program since 1960 leading to the release of productive varieties. Information of the genetic diversity for these varieties could improve the effectiveness of further breeding programs. The objectives of this study was to assess the genetic diversity and the population structure of 11 cowpea improved varieties from ISRA collection. Twelve (12) polymorphic microsatellite markers were used and the analysis of genotypic data showed a total of 39 alleles ranging from 2 (SSR6288, SSR6311 and SSR6827) to 6 (SSR6807) per locus. Polymorphism rate ranged from 8.33% (Mougne and Kelle) to 58.33% (Mouride) with an average of 31.06%. Intra varietal genetic diversity was very weak (0.012 to 0.091). The genetic similarity revealed that Melakh and Pakau varieties were genetically the closest while Bambey 21 and Sam were the most distant. These results are confirmed by the dendrogram, which also showed that Thieye, Leona, Kelle, Sam, Mougne and Yacine varieties have a higher genetic stability than Lisard, Melakh, Pakau, Mouride and Bambey 21. Eighty-seven percent (87%) of the total variability was attributed to inter varietal variability while 17% was due to intra varietal variation. These results provide a better knowledge of genetic resources of cowpea varieties released and held by ISRA and constitute important input for further cowpea breeding programs.

Este estudo teve como objetivo principal compreender a percepção da população do entorno da área de implantação da barragem destinada ao abastecimento humano no rio Cupissura, estado da Paraíba, além de caracterizar o perfil socioeconômico dessa população, identificar os principais problemas ambientais existentes. A preocupação com as intervenções antrópicas capazes de comprometer a capacidade de auto sustentabilidade dos ambientes aquáticos e a conservação dos recursos naturais tem sido alvo de interesse de pesquisadores das diferentes áreas do conhecimento, especialmente das ciências geográficas. A partir deste contexto, tais estudos permitem identificar aspectos positivos e negativos. Assim sendo, a maior parte da população entrevistada (63,69%) é considerada analfabeta funcional, sem formação técnica e possuem renda familiar de até um salário mínimo. Em relação a implantação da barragem, cerca de 56,55% consideram que a sua construção não resultará em benefícios para população da região.

O trigo é a espécie com maior potencial de uso no período de inverno e estudos sobre a produtividade dos genótipos e forma de utilização do nitrogênio (N) na cultura, demonstram elevada importância. O estudo tem o objetivo de avaliar os componentes de rendimento e a produtividade de diferentes cultivares de trigo, submetidas a aplicação de N parcelado ou em dose única. O experimento foi conduzido no município de Realeza – Paraná, em delineamento de blocos ao acaso, com três repetições. Avaliou-se diferentes cultivares (Toruk, Sonic, Sossego e Sintonia) e duas formas de aplicação de N (parcelado e dose única). Mensurou-se o número de espiguetas e grãos por espiga, comprimento da espiga, produtividade e pH dos tratamentos. O comprimento da espiga é maior para a cultivar Sossego (8,87 cm) e menor para a cultivar Sintonia (7,63 cm). Sonic, juntamente com Sossego e Sintonia exibiram maior número de espiguetas por espiga e Sossego e Sonic maior número de grãos por espiga, quando o N foi aplicado parcelado. O pH do trigo é maior na cultivar Toruk (81) em relação as demais cultivares, quando o N é aplicado parcelado. Sonic apresenta menor pH entre as cultivares quando a adubação é realizada em dose única. Sintonia e Toruk apresentam aumento de produtividade de 243 e 665 kg ha-1, quando o N é aplicado em dose única. Entre as cultivares, Sossego, seguida de Toruk, Sintonia e Sonic proporcionaram maior produtividade respectivamente, independente da forma de aplicação de N. De modo geral, ocorreu uma variabilidade na resposta da produtividade e qualidade dos grãos de trigo em relação a cultivar e o modo de suprimento de N, devido às diferenças de demanda nutricional das cultivares, no entanto, fica evidente que o fornecimento de N é essencial na triticultura, principalmente em períodos que antecedem a maior demanda nutricional, levando os materiais genéticos mais próximos a atingir o máximo potencial produtivo.

O rabanete (Raphanus sativus L.) exige boa disponibilidade hídrica e fertilidade do solo. O manejo da irrigação é indispensável, assim como adubação. Objetivou-se avaliar a cultura do rabanete em função de diferentes lâminas de irrigação e doses de adubação nitrogenada. O experimento foi realizado na Universidade Federal de Alagoas, Campus de Arapiraca com delineamento em blocos casualizados em fatorial 5x5 com quatro repetições. Os tratamentos consistiram em cinco lâminas de água com 50%, 75%, 100%, 125% e 150% da evapotranspiração da cultura, com cinco doses de adubação nitrogenada correspondendo a 50%, 75%, 100%, 125%, e 150% da recomendação para a cultura. As variáveis analisadas foram o índice SPAD e o grau BRIX. Para o grau BRIX foi significativo apenas para o fator lâmina com um com comportamento decrescente e um ponto mínimo de 3,82% na lâmina de 196,67 mm. Já a variável índice SPAD foi significativa para a interação entre os dois fatores, com o ponto máximo na lâmina de 187,53 mm e adubação de 45,43 Kgha-1. A lâmina de irrigaçã

Para minimizar as perdas de produtividade causadas pelo o uso de água de qualidade inferior, antioxidantes podem ser aplicados na forma exógena, sendo o Ácido Ascórbico (AsA) um dos mais importantes. Objetivou-se avaliar o efeito da aplicação de AsA via foliar para redução dos efeitos da salinidade na cultura da couve folha (Brassica oleracea L). O experimento foi conduzido na Universidade Federal de Alagoas (UFAL) - Campus de Arapiraca, em ambiente protegido. O delineamento experimental foi o inteiramente casualizado, esquema fatorial 4x3, com 5 repetições. Utilizou-se níveis de salinidade (S1: 0,12; S2: 1,62; S3: 2,62 e S4: 4,12 dS.m-¹) e doses de AsA (A1:0; A2: 5 e A3: 20 mM). Analisou-se: altura de planta (AP), número de folhas (NF) e comprimento da raiz (CR). O nível de tolerância da couve folha à salinidade foi de 1,62 dS.m-1, porém a AP e o CR não foram afetados até os níveis de 2,2 e 4,2 dS.m-1, respectivamente. O uso exógeno de AsA mostrou-se pouco promissor ou recomendável para reverter ou minorar os efeitos da salinidade sobre o crescimento de couve folha. PALAVRAS CHAVE: Recursos hídricos; antioxidantes; salinidade.

Bu çalışmada, tek bölgeli bir güç sisteminde yük frekans kontrolü (YFK) gerçekleştirilmiştir. Yük frekans kontrolü, sistemdeki ani yük değişimleri sonucu artan veya azalan frekansı nominal değerinde tutma işlemidir. Yapılan çalışmada, öncelikle tek bölgeli güç sistemi MATLAB/SIMULINK ortamında modellenmiştir. Daha sonra kontrolör olarak klasik PI kontrolör ve bulanık PI kontrolör kullanılarak frekans değişiminin sıfır olması amaçlanmıştır. Sisteme uygulanan yük değişimlerine karşı sistemin frekansında meydana gelen değişimler her iki kontrolör için elde edilmiştir. Bulanık PI kontrolör ve klasik PI kontrolör için elde edilen sonuçlar, sistem frekansının nominal değerine ulaşma sürelerinin her iki kontrolör için hemen hemen aynı olduğunu, sistemin aşma değerinin ise bulanık mantık kontrolörde klasik PI kontrolöre göre daha az olduğunu göstermiştir.

Tuz stresi (100 mM NaCl) altındaki hıyar (Cucumis sativus L.) genotipinde (Beith Alpha F1) ekzojen salisilik asit uygulamasının fotosistem II aktivitesi üzerindeki etkileri klorofil a fluoresansı tekniği yardımıyla araştırılmıştır. 10 günlük hıyar fidelerine 100 mM tuza karşı 50 µM salisilik asit 5 gün süreyle uygulanmıştır. 5. günün sonunda yapılan klorofil a fluoresansı ölçümleri değerlendirilmiştir. Tuz stresi hıyar yapraklarında fotosistem II’nin hem donör hem de akseptör bölgesindeki elektron hareketlerini inhibe etmiştir. Ayrıca tuz stresinin hıyar bitkisinde aktif reaksiyon merkezi miktarını ve kinonA ile plastokinonun indirgenme yeteneğini azalttığı, indirgenmiş reaksiyon merkezlerinin birikimini ve ısı enerjisi kaybını artırdığı belirlenmiştir. Salisilik asit uygulaması ise hıyar bitkilerinde tuz stresinin fotosistem II’nin donör ve akseptör bölgesindeki elektron hareketleri üzerindeki olumsuz etkisini ortadan kaldırmıştır. Ek olarak salisilik asit uygulaması hıyar yapraklarındaki aktif reaksiyon merkezi miktarını ve kinonA ile plastokinonun indirgenme yeteneğini artırırken, indirgenmiş reaksiyon merkezi miktarını ve ısı enerjisi kaybını azaltmıştır. Sonuç olarak salisilik asidin hıyar yapraklarında tuz toleransını artırdığı ve bu yaklaşımın tarımsal amaçlarla kullanılabileceği söylenebilir.

Due to unique properties of perovskite materials, the solar cells technologies based on those materials rapidly advance to the maximum theoretical conversion efficiency of about 32 %. This study reports the simulation results of CH3NH3PbI3-xCIx based perovskite solar cells using SCAPS-1D software. ZnO is used as common electron transfer medium (ETM), whereas Cu2O, CuI and CuO materials are separately used for hole transfer medium (HTM) each time. The cell basic parameters (Voc, Jsc, FF and efficiency) are simulated at various conditions. CuO is found to be the best HTM material, whereas the maximum efficiency of ̴26.8 % is obtained at 0.55 µm thickness of CH3NH3PbI3-xCIx material with a donor atom density of about 1017 cm-3.
