Non-healthcare workers with a high potential for exposure to severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) may contribute to the virus spreading. Data among asymptomatic and high exposure risk populations is still scarce, in particular Chiang Mai and Lamphun provinces, Thailand. We conducted a cross-sectional observational study aiming to assess the prevalence of SARS-CoV-2 RNA positivity, anti-SARS-CoV-2 IgM/IgG, and potential associated factors among asymptomatic/mild symptomatic individuals with a high exposure risk in Chiang Mai and Lamphun provinces, during the second wave of outbreak in Thailand (November 2020–January 2021). Socio-demographic data was collected through an on-line questionnaire prior to collection of nasopharyngeal/throat swab samples and blood samples tested for SARS-CoV-2 RNA (DaAn Gene, China) and anti-SARS-CoV-2 IgM/IgG antibodies (commercial lateral flow immunoassays), respectively. Univariable and multivariable logistic regression analysis were used to analyze associated factors. None of 1,651 participants were found positive for SARS-CoV-2 RNA (0%, 95% confidence intervals, CI: 0–0.2). Fourteen were positive for anti-SARS-CoV-2 IgM/IgG antibodies (0.9%, 95% CI: 0.5–1.4), including 7 positives for IgM and 7 positives for IgG (0.4%, 95% CI: 0.2–0.9). Being over 50 years old was independently associated with virus exposure (OR: 5.8, 95% CI: 1.0–32.1%, p = 0.045). Despite high exposure risk, no current infection was found, and a very high proportion was still susceptible to SARS-CoV-2 infection and would clearly benefit from vaccination. Continuing active surveillance, rolling out of vaccination and monitoring response to vaccine will help better control the COVID-19 spread.

Published: February 2022

Introduction

Elderly patients with acute myeloid leukemia not eligible for intensive antileukemic therapy are treated with less intensive therapies, uncertainty remains regarding their relative merits.

Objectives

To compare the effectiveness and safety of less intensive antileukemic therapies for older adults with newly diagnosed AML not candidates for intensive therapies.

Methods

We included randomized controlled trials (RCTs) and non-randomized studies (NRS) comparing less intensive therapies in adults over 55 years with newly diagnosed AML. We searched MEDLINE and EMBASE from inception to August 2021. We assessed risk of bias of RCTs with a modified Cochrane Risk of Bias tool, and NRS with the Non-Randomized Studies of Interventions tool (ROBINS-I). We calculated pooled hazard ratios (HRs), risk ratios (RRs), mean differences (MD) and their 95% confidence intervals (CIs) using a random-effects pairwise meta-analyses and assessed the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

Results

We included 27 studies (17 RCTs, 10 NRS; n = 5,698), which reported 9 comparisons. Patients were treated with azacitidine, decitabine, and low-dose cytarabine (LDAC), as monotherapies or in combination with other agents. Moderate certainty of evidence suggests no convincing difference in overall survival of patients who receive azacitidine monotherapy compared to LDAC monotherapy (HR 0.69; 95% CI, 0.31–1.53), fewer febrile neutropenia events occurred between azacitidine monotherapy to azacitidine combination (RR 0.45; 95% CI, 0.31–0.65), and, fewer neutropenia events occurred between LDAC monotherapy to decitabine monotherapy (RR 0.62; 95% CI 0.44–0.86). All other comparisons and outcomes had low or very low certainty of evidence.

Conclusion

There is no convincing superiority in OS when comparing less intensive therapies. Azacitidine monotherapy is likely to have fewer adverse events than azacitidine combination (febrile neutropenia), and LDAC monotherapy is likely to have fewer adverse events than decitabine monotherapy (neutropenia).

Introduction

With the emergence of the COVID-19 pandemic, universities immediately responded to protect students’ lives by implementing e-learning in order to stop the spread of the communicable disease within the academic population. This study aimed to describe iranian nursing students’ experiences of e-learning during the COVID-19 pandemic.

Materials and methods

The current study used a qualitative descriptive study. Ten nursing undergraduate students from a single Iranian university identified using purposive sampling methods. Face-to-face semi-structured interview conducted from May to July 2021 and analyzed through thematic analysis. Lincoln and Goba criteria were used to obtain data validity and reliability.

Results

Four themes emerged including"novelty of e-learning","advantages of e-learning", "disadvantages of e-learning"and"passage of time and the desire to return to face education". Participants evaluated e-learning as a novel method without proper infrastructure, it was initially confusing but became the new normal as their knowledge of the way to use it improved. Advantages included self-centered flexible learning and reduction in their concerns experienced with face-to-face learning. Disadvantages including changing the way they interact with teachers, decreasing interactions with classmates, problems with education files, superficial learning, hardware problems, family members’ perceptions of the student role, interference of home affairs with e-learning, cheating on exams and assignments and being far away from the clinical context.

Conclusion

The findings revealed that e-learning has been introduced as a new method for the current research participants and despite the perceived benefits, these students believed that e-learning could supplement face education but not replace it.
From resilience to satisfaction: Defining supply chain solutions for agri-food SMEs through quality approach
Authors: Wicaksono Tutur , Illés Csaba Bálint
Published: February 2022

Since it is an important human need and many organizations are involved in the value chain, the agricultural food supply chain is exposed to various risks that arise naturally or through human actions. This study aims to develop the application of a quality function deployment approach to increase the resilience of the food supply chain by understanding customer needs and logistical risks in the food supply chain. In-depth studies with empirical analysis were conducted to determine the importance of customer needs, food supply chain risks, and actions to improve supply chain resilience of SMEs in the agri-food industry. The result shows that the top three customer needs are "attractive, bright color", "firm texture" and "fresh smell". The top three risks in the agri-food supply chain are "improper storage," "Harvest Failure" and "Human Resource Risks" and the top three resilience actions are "continuous training," "preventive maintenance," and "supply chain forecasting." The implications of this study are to propose an idea that broadens the perspective of supply chain resilience in the agri-food industry by incorporating the needs of customers in considering how to mitigate the existing risks to the satisfaction of customers, and it also highlights the relatively low skill and coordination of the workforce in agri-food supply chains.

La Traduction et l’alternance de code linguistique dans la musique de Yemi Alade
Authors: Lipenga Timwa
Published: February 2022

This article focuses on the links between translation and code-switching in selected songs by Yemi Alade. The songs under study were originally composed and interpreted in English before being translated into French. The original lyrics do not translate the instances where Yoruba and Igbo code-switching occurs, whereas the French versions frequently translate such instances. The article argues that these translations of code-switching serve to re-examine preconceived notions about a song and its translation. The argument demonstrates that it is possible for a song to ‘gain’ in translation, and this is illustrated by Alade’s translated songs. The article also focuses on the extent to which the Derridean perspective of the supplement and that of différance can be applied to music translation. The four songs ‘Johnny’, ‘K-I-S-S-I-N-G’, ‘Africa’ and ‘Ferrari’ have been chosen because they feature instances of code-switching. The article looks at the degree to which one can talk about loss during translation and the supplementary meanings of language in the four songs. finally, it reflects on the implications of linguistic choices for a musician in postcolonial Africa; ordinarily, African writers are the ones who are interrogated regarding language choice, but the question of language is one which confronts every form of art on the continent.

Toros y política en el siglo XX: una pasión correspondida
Authors: González Fernández José Luis
Published: February 2022

Con el Desastre del 98, que abre el debate sobre el Problema de España, toros y política se revelan como dos elementos indisociables. Asimismo, la rápida politización de la vida pública durante la dictadura de Primo de Rivera coincide con la irrupción del deporte y la cultura de masas, que, en España, incrementa el interés por el fútbol y los toros. Así lo demuestra el auge de las corridas de toros en la Segunda República y, sobre todo, la Guerra Civil, que politiza para siempre dichos festejos y activa muchos de los estereotipos que arrastraba España desde hacía siglos. En cualquier caso, al terminar el franquismo y dar comienzo la transición a la democracia, los toros son ya un símbolo aceptado universalmente como español, lo que explica el progresivo rechazo por parte del independentismo catalán y, finalmente, la prohibición de las corridas de toros en Cataluña.
A magyar kultúraszemélyiség észlelésének különbségei a magyarok és a külföldiek között
Authors: Malota Erzsébet , Gyulavári Tamás
Published: February 2022

Kutatásunk célja a magyar kultúráról, a magyarokról alkotott percepciók feltérképezése. Azt tanulmá­nyoztuk egy 1566 fős online minta felmérése során, hogy a nálunk tanuló külföldi hallgatók hogyan látják a magyarokat és Magyarországot, milyen spontán negatív és pozitív szavakat társítanak hozzánk. Emel­lett szemantikus differenciálskála használatával vizsgáltuk az észlelt magyar kultúraszemélyiséget, mely során 11 különböző országból származó hallgatók percepcióit vetettük össze arra fókuszálva, hogy milyen eltérések mutathatók ki a hallgatók származási országát figyelembe véve. A külföldiek észleléséről kapott eredményeket összevetettük a magyarokban önmagukról élő képpel.

A leggyakrabban elhangzó pozitív kifejezések rólunk a „szépség”, „kedvesség” és a „barátságosság”, a negatív szavakra rákérdezve pedig legtöbbször azt a választ kaptuk, hogy „nincs negatívum”.

Eredményeink azt mutatják, hogy a kultúra személyiségére vonatkozóan minden jellemzőt illetően a külföldiek által adott átlagok a magasabbak, csak két személyiségjegyben értékeljük önmagunkat kedve­zőbben: humorosabbnak és különlegesebbnek ítéljük meg magunkat, mint a külföldiek. A válaszok alapján eltérések mutathatók ki a külföldiek származási országát tekintve: a fejlettebb országok válaszadói (például a németek és a japánok) kedvezőtlenebb, a kevésbé fejlett országokból származók (például az indiaiak, algé­riaiak és a nigériaiak) pedig jóval pozitívabb színben látnak bennünket.

Published: February 2022

A globális turizmust fenyegető biztonsági kockázatok negatív hatásai, az iparágra jellemző multiplikátor­hatásból adódóan, a gazdaság egészére továbbgyűrűznek. Azonosításuk mind fogyasztói, mind szolgáltatói oldalról szükségszerű, minimalizálásuk és kiküszöbölésük az értékteremtés feltétele. A turisztikai desztiná­ciókat sújtó katasztrófákra, krízishelyzetekre történő felkészülésben, és az azokat követő válságkezelésben a megfelelő menedzsment- és marketingszemlélet alkalmazása a szektor további „sérülésének” megaka­dályozását, illetve mielőbbi helyreállítását célozza. A válságkezelési gyakorlat szemléltetése egy angliai száj- és körömfájás járvány, valamint egy ausztrál bozóttűz esetein keresztül történik.
Mit várunk a szállodáktól? – avagy a legmeghatározóbb fogyasztói szegmens számára értéket jelentő tényezők a szállodákban
Authors: Kulcsár Noémi , Grotte Judit
Published: February 2022

Napjainkban a turisztikai és szállodai szolgáltatások iránti kereslet és legfőképpen az élmények tartalma átalakult, és szegmensenként más-más elvárásokkal és értéket jelentő tényezőkkel párosult. Ez a fogyasz­tói szokásokban végbemenő változás nagy mértékben határozza meg a turisztikai szolgáltatók, ezen belül is a szállodák menedzsment és marketing tevékenységét itthon és külföldön egyaránt. Jelen tanulmány a legmeghatározóbb fogyasztói szegmens, az Y és Z generáció, esetében vizsgálja kérdőíves felmérés se­gítségével a szállodai tartózkodásuk során számukra értéket jelentő tényezőket. A vizsgálat a fogyasztói értéknek a szakirodalomban elterjedt kognitív – affektív értékdimenziós lehatárolása alapján történt. Az elemzés során meghatároztuk a szegmens számára értéket és a szállodai szolgáltatások közül élményt je­lentő tényezőket, valamint azonosítottuk utazásuk alatti viselkedésük jellemzőit. Ezt követően generációs bontást végeztünk, és nem parametrikus varianciaanalízis segítségével megvizsgáltuk az Y és a Z generá­ció számára értéket jelentő tényezők közötti különbséget.
A kerékpáros turizmus lehetőségei Magyarországon a vasúti kerékpárszállítás adottságainak függvényében
Authors: Somogyi Bence
Published: February 2022

A turistaérkezések elmúlt évekbeli folyamatos növekedése azt eredményezte, hogy előtérbe kerültek olyan alternatív, az egyén fizikai, szellemi és mentális állapotán, illetve azok minél teljesebb igényű kielégítésén nyugvó turisztikai termékek, mint a környezetkímélő közlekedési, rekreációs és turisztikai lehetőséget nyújtó kerékpáros turizmus. A kerékpározás divatossá válásának eredményeként bővült a kerékpárral együtt utazók számára nyújtott szolgáltatáshalmaz, amely magában foglalja a kerékpárral együtt történő közlekedési lehetőségeket. Magyarországon kerékpár szállítása kizárólag helyközi kötött pályás közlekedési eszközön (vasút) szállítható, ami a kerékpározási szokások térbeli expanzióját mindenképpen korlátozza. Emellett a vasúti szolgáltatók kerékpárszállítási lehetőségeit is figyelembe kell venni a kerékpáros turiz­mus közlekedéssel és szállítással szembeni követelményeinek érdemi vizsgálatához. A tanulmány célja, hogy bemutassa a vasúton történő kerékpárszállítás keresleti és kínálati oldalát, valamint a turisztikai szempontú lehetőségeinek bővítését.
A Tripadvisor kiemelt turisztikai fejlesztési térségekre vonatkozó vendégelégedettségi adatainak elemzése
Authors: Mártonné Máthé Kinga , Simonyi Norbert
Published: February 2022

Az elsősorban amerikai és európai utazók által használt, több mint 500 millió értékelést tartalmazó Tripad­visor vendégelégedettségi és visszajelzési adataiból nyert mutatószámok több esetben egybecsengenek mind a KSH turisztikai vendégforgalmi számaival, mind a Magyar Turisztikai Ügynökség saját kutatá­saival és adataival. Általánosságban elmondható, hogy szoros összefüggés van az értékelések minősítése és a vendégszám alakulása között, azaz a több és jobb értékelést kapott desztinációkban magasabb a tu­ristaforgalom, ami fordítva is igaz. A tanulmány arra is rávilágít, hogy a Nemzeti Turizmusfejlesztési Stratégia (NTS) térségi lehatárolása, célrendszere, pillérei és horizontális célkitűzései döntően megfelel­tethetők a Tripadvisor használók szubjektív elvárásainak, problémafelvetéseinek és a bejegyzések területi eloszlásának. Mindezekből következően a már kijelölt, illetve a továbbiakban kiemelni tervezett turisztikai fejlesztési térségek esetében fontos adatokhoz és visszajelzésekhez jutottunk a szükséges beavatkozások mélységét és irányát tekintve.
Repülőjegyek dinamikus árazásának hatása a fogyasztók által észlelt méltányosságra
Authors: Omarli Sevinj , Claro Dániel , Gyulavári Gyulavári
Published: February 2022

Jelen kutatás célja az volt, hogy megvizsgálja, milyen hatást gyakorol a légitársaságok dinamikus árazási gyakorlata a fogyasztók által észlelt méltányosságra, illetve az észlelt méltánytalanság mennyiben függ össze a vásárlási hajlandósággal. Mindezek mellett megvizsgáltuk az árpozíció moderáló hatását is, azaz mennyire erősíti, illetve gyengíti a dinamikus árazási gyakorlat és az észlelt méltányosság közötti összefüggést, ha az előbbi hatására megváltozik az adott ár elhelyezkedése a piaci kínálatok megoszlásában.
Az irodalmi áttekintés alapján egy kutatási modellt fejlesztettünk ki, amelyet egyetemi hallgatók körében teszteltünk. Az eredmények azt mutatják, hogy a dinamikus árazásnak negatív hatása van a fogyasztók termékvásárlási hajlandóságára és ebben közvetítő szerepet játszik az észlelt méltányosság. Mindemellett kimutatható volt, hogy amennyiben a dinamikus árazás következtében az adott ár egy drágább kategóriába kerül a piacon meglévő kínálat rangsorában, jóval erősebb lesz a fogyasztókban az árazási gyakorlattal szembeni ellenérzés. Mindez visszahat az adott szolgáltató iránti keresletre is.
Estimating the Aboveground Biomass of Urban Trees by Combining Optical and Lidar Data: A Case Study of Hengqin, Zhuhai, China
Authors: Bai Linze , Cheng Qimin , Shu Yuxuan , Zhang Sihang
Published: February 2022

The aboveground biomass (AGB) of trees plays an important role in the urban ecological environment. Unlike forest biomass estimation, the estimation of AGB of urban trees is greatly influenced by human activities and has strong spatial heterogeneity. In this study, taking Hengqin, China,
as an example, we extract the tree area accurately and design a collaborative scheme of optical and lidar data. Finally, five evaluation models are used, including two deep learning models (deep belief network and stacked sparse autoencoder), two machine learning models (random forest and
support vector regression), and a geographically weighted regression model. The experimental results show that the deep learning model is effective. The result of the stacked sparse autoen - coder, which is the best model, is that R2 = 0.768 and root mean square error = 18.17
mg/ha. The results show that our method can be applied to estimate the AGB of urban trees, which greatly influences urban ecological construction.
Cloud Detection in ZY-3 Multi-Angle Remote Sensing Images
Authors: Huang Haiyan , Cheng Qimin , Pan Yin , Lyimo Neema Nicodemus , Peng Hao , Cheng Gui
Published: February 2022

Cloud pollution on remote sensing images seriously affects the actual use rate of remote sensing images. Therefore, cloud detection of remote sensing images is an indispensable part of image preprocessing and image availability screening. Aiming at the lack of short wave infrared and
thermal infrared bands in ZY-3 high-resolution satellite images resulting in the poor detection effect, considering the obvious difference in geographic height between cloud and ground surface objects, this paper proposes a thick and thin cloud detection method combining spectral information
and digital height model (DHM) based on multi-scale features-convolutional neural network (MF-CNN) model. To verify the importance of DHM height information in cloud detection of ZY-3 multi-angle remote sensing images, this paper implements cloud detection comparison of the data set with and
without DHM height information based on the MF-CNN model. The experimental results show that the ZY-3 multi-angle image with DHM height information can effectively improve the confusion between highlighted surface and thin cloud, which also means the assistance of DHM height information can
make up for the disadvantage of high-resolution image lacking short wave infrared and thermal infrared bands.
Apresentação - Dossiê - Psicologia Histórico-Cultural na Educação Básica: práticas e pesquisas
Authors: Asbahr Flávia da Silva Ferreira , Pessoa Camila Turati
Published: February 2022

As interfaces entre Psicologia e Educação constituem-se como campo de pesquisa e prática profissional na construção de intervenções que incidem junto aos processos de desenvolvimento, aprendizagem e apropriação do conhecimento que ocorrem na educação escolar. Historicamente sabemos que um dos primeiros campos no qual a Psicologia explorou em seu processo de tornar-se ciência, ainda no final do século XIX, foi a Educação, com investigações que buscavam justificar as denominadas dificuldades de aprendizagem atribuindo-as à criança, sua família, ou no máximo ao ambiente pertencente aos alunos, tomando tais fatores como explicação às causas para esses problemas, conforme já foi fortemente denunciado por Patto (1984, 1999). Desde o final dos anos 80 e, mais especificamente a partir dos anos 90, vemos no Brasil o esforço para construir uma Psicologia com olhar e atuação em uma perspectiva crítica na educação escolar, como em Souza (2021), Souza, Silva e Yamamoto (2014), Facci (2004, 2007), Tanamachi e Meira (2003), Machado e Souza (2000), entre muitos outros exemplos.

Este artigo tem por objetivo expor o percurso desenvolvido desde a gênese, o processo e os resultados de um projeto de pesquisa interinstitucional que surgiu das demandas das secretarias de educação de municípios do Paraná. Destacamos a característica de originalidade da pesquisa devido aos processos que conformaram sua realização, que envolveu, a partir dos fundamentos da psicologia Histórico-Cultural, ações teórico-práticas nos municípios. O trabalho abrangeu diferentes segmentos da organização social dessas cidades, culminando com diferentes produções científicas e de alcance popular, numa demonstração da unidade entre pesquisa-ensino-extensão. Destacamos, na organização, as tomadas de decisão e os estudos coletivos; no aspecto teórico, o aprofundamento nos estudos sobre o desenvolvimento infantil na perspectiva da Psicologia Histórico-Cultural, pautados na observância contínua de não abstrair seus fundamentos teórico-metodológicos, ou seja, o materialismo histórico e dialético. Trataremos dos princípios teórico-metodológicos estudados, na unidade forma e conteúdo, como articuladores de todas as ações realizadas. Por fim, apresentaremos as ressonâncias do projeto ainda existentes no interior dos municípios, uma vez que, quando se conclui um projeto que abarcou oito anos, este se finaliza apenas formalmente, pois seu aspecto “formador” não se encerra, o que nos afirma a importância dos processos educativos e seus resultados que não são imediatamente perceptíveis.
Produtividade do trabalho e a lei geral da acumulação capitalista
Authors: Valada Machado Fernanda
Published: February 2022

Este ensaio propõe entender o sentido do progresso tecnológico dentro das relações sociais de produção capitalista, com foco nos significados da acumulação para a classe trabalhadora. Para isso, é analisado o desenvolvimento teórico de Marx da lei geral da acumulação capitalista. Entende-se que a produtividade social do trabalho sob o modo de produção capitalista não incorpora o progresso técnico com o objetivo de ampliar o bem-estar dos trabalhadores, mas sim o subordina à espiral da acumulação de capital e, consequentemente, expande as contradições imanentes do capital.
O Federal Reserve (FED) no palco central: navegando por águas proibidas
Authors: Duménil Gérard , Lévy Dominique
Published: February 2022

A principal ameaça iminente da pandemia à economia dos EUA é o aumento do endividamento das empresas e do governo. O Federal Reserve agiu de forma espetacular no apoio ao crédito, e este é apenas o começo de uma longa história. O apoio dos mecanismos de crédito pelo Federal Reserve já estava em andamento antes da crise da COVID-19. Novos graus foram alcançados e novos caminhos estão sendo abertos atualmente, como empréstimos diretos às empresas pelo FED. Os limites são, no entanto, cumpridos por razões políticas e ideológicas: Conforme mencionado anteriormente, não havia uma política voltada à preservação da receita de vendas das empresas.  A continuação da nova trajetória de taxas de juros muito baixas e o financiamento direto do Federal Reserve enfrentará fortes resistências por parte de interesses financeiros. Isso transformaria os bancos como credores em meros intermediários na concessão de empréstimos (cobrança de taxas aos mutuários), como já é o caso da intermediação financeira não-bancária.

STUDY OF LIVING HADITH TOWARDS KUBRO SISWO ARTS AS ISLAMIC SYI'AR
Authors: Al-Anwari Ahmad Ubaidillah Ma'sum , Wicaksono Bagus , Saputro Danang Wahyu
Published: February 2022

Art is a medium of da'wah that grows and develops until now. Islam brought by the guardians to the archipelago has a basis on symbols, including symbols in art. If art is explored more deeply, it will be understood things that are closely related to religious texts. Kubro Siswo is the art of dance accompanied by music and syi'ir-syi'ir that contains advice. This art is not only limited to spectacle, but also demands that are conveyed through the syi'ir-syi'ir. Kubro Siswo is usually displayed in big events, such as the month of independence, Isra 'Mi'raj, and other events. The phenomenon of Kubro Siswo's art becomes very interesting to study. Based on the phenomenological theory, it will appear that this art has a considerable impact on the life of the Magelang community. This art not only functions as a spectacle that teaches love for ancestral traditions, but also as a means of da'wah that always invites people to cultural values that are in line with Islamic law. Every poem sung in Kubro Siswo's art has a deep meaning, which contains an invitation to goodness that is indirectly sourced from the Qur'an and Hadith.

Delayed encounters with stress are identified with poor individual well-being and related to significant monetary expenses for the general public. Accordingly, the advancement of cost-effective stress prevention or stress management tactics has turned into a vital attempt at recent research endeavors. Music has been appeared to influence physiological, cognitive, and emotional stress-related procedures advantageously. Subsequently, the utilisation of tuning in to music as a financial, non-intrusive, and profoundly acknowledged mediation apparatus has gotten uncommon enthusiasm for the administration of stress and stress-related medical problems. “Raga is the grouping of chosen notes (swaras) that loan suitable ‘temperament’ or feeling in a specific blend. “Raga therapy means healing through the raga. It’s a yoga framework with the help of resonant sounds. Ragatherapy implies curing through the raga. It is the information on the most proficient method to utilise raga for curing [1]”. Symphonies of raga ensure a calming influence on the mind and body. Researchers have found the role of raga therapy in treating stress. In the present research, raga therapy was administered to 74 subjects suffering from stress as an intervention plan. The ISMA questionnaire was administered to them before and after the intervention. Different sequences of ragas were directed to them for 30 min. A significant effect of raga therapy established on stress management.

The study has been undertaken to evaluate the performance of locally available commercial cultivars of cabbage in open field during summer season of 2019 at Defence Research Laboratory Research and Development Centre Tawang (Arunachal Pradesh). The commercial cultivars of these vegetables were evaluated based on the growth parameters and their yield performance under open field with paired row system of planting. It was found that the cultivar Green Express performance was outstanding among test edcultivars and it superseded cv. Royal Ball BC-51 and cv. Blue Jayes in terms of growth parameters as well as marketable yield (2.62 kg/m2) and biological yield (3.47 kg/m2). The cv. Royal Ball BC-86 was also found next best performing cultivar after cv. Green Express as former was at par with growth and yield parameter and harvest maturity of later. The head of cv. Green express attended harvest maturity (149.25 days) approximately one week earlier as compared to cv. Blue Jayes (155.0 days). However, the productivity of cultivars Green Express and Royal Ball BC-86 was found within the range of national average, therefore, these two cultivars could be recommended for the commercial cultivation with paired row system of planting under open field cultivation during summer season in high altitude areas of Tawang (Arunachal Pradesh).

Auriculoterapia é a utilização de pontos nas orelhas para tratamento de diversos sinais e sintomas comuns em diferentes patologias e atua no âmbito físico, mental e emocional do paciente. É útil para diagnosticar e tratar disfunções de origem orgânica, nervosa ou somática pautadas em diferentes racionalidades em saúde. Em virtude dos desgastes dos  profissionais de saúde atuantes na atenção primária foi sugerido a oferta de sessões desse tratamento com a colocação de pontos auriculares e sangria para restaurar o equilíbrio energético e aliviar sintomas exacerbados decorrentes da pandemia. Em um período de dois meses, foram atendidos 45 profissionais. Foi realizado um instrumento de avaliação pelo cuidador farmacêutico da atenção primária à saúde e os principais sintomas abordados foram ansiedade, tensão muscular, estresse, dor de cabeça, insônia, baixa da imunidade, impaciência (raiva e agressividade), desconforto respiratório e alergia. Por meio da análise individual, foi proposto um esquema terapêutico para início imediato. A duração foi de oito sessões, uma vez por semana, para cada indivíduo. Com o decorrer das semanas, os sintomas relatados foram amenizados e, na totalidade dos casos, êxito completo do tratamento até o término proposto. Nota-se que com o tratamento individualizado consegue-se obter melhor resultado. A técnica da auriculoterapia no cuidado farmacêutico dos profissionais da equipe multidisciplinar teve grande sucesso ao trazer a melhoria da qualidade de vida, menor utilização de medicamentos, menor índice de afastamentos na atenção primária em época de pandemia (Covid-19).

Climate change is one of the critical defining concerns today’s world, altering earth ecosystem. Drought stress management is a major issue in agricultural and crop research, mainly negatively impacting rice growth and yield. Abscisic acid (ABA) is a plant stress hormone that plays a crucial role in regulating, and mitigating drought stress. The objective of this study was to evaluate the effect of exogenously applied ABA and adaptation strategies responding to concrete challenges four rice varieties (ASD-16, ADT-45, TKM-13 and CO-50) and analysed growth characteristics, physiological, biochemical and antioxidative enzyme activities induced by polyethylene glycol (2 % and 4 %) drought stress and exogenously application of ABA (100 µM). The present findings help predict the degree of drought resistance variety of rice. The experiment was designed by six different treatments, such as control plants, control + ABA, polyethylene glycol induced drought (2 % and 4 %), and combination treatment of 2 % and 4 % PEG with exogenous application of ABA (100 µM). Exogenous ABA treatment significantly increased in morphological characteristics compared to control. The chlorophyll pigments, RWC, biochemical parameters such as reducing sugar, starch, protein and antioxidant activities of CAT, POD were increased and proline content was decreased at PEG 2 % and 100 µM ABA-treated rice in TKM-13 compared to ASD-16, ADT-45, CO-50. There were statistically significant morphological, physiological and biochemical parameters between treatments. The present findings depict that four rice varieties under drought imposition decrease the growth characteristics, physiological and biochemical content. However, the PEG induced drought (2 %) and foliar application of ABA (100 µM) were found to increase morphology, physiological and biochemical contents and can provide valuable insights into plants’ drought responses and may help identify novel drought tolerance traits.
Still the Lands of Equality? Heterogeneity of Income Composition in the Nordics, 1975–2016
Authors: Iacono Roberto , Palagi Elisa
Published: February 2022

According to standard measures of income inequality, the Nordic countries rank among the most equal economies in the world. This paper studies whether and how this picture changes when the focus is on inequality of income composition, meaning the heterogeneity in individuals’ factor income shares. We show that, for all countries, a shift in capital incomes toward the top since the early 1990s causes rising heterogeneity in individuals’ factor income shares. To explain this result, we highlight the role of dual taxation systems. For Denmark in 2009–2013, Finland (1990–2007), and Norway (1991–2005), rising capital shares contributed to changes in personal income inequality, while for Sweden our results lead to disregard the capital share as a determinant of increasing income inequality.
Comparison of four indirect (data mining) approaches to derive within-subject biological variation
Authors: Tan Rui Zhen , Markus Corey , Vasikaran Samuel , Loh Tze Ping
Published: February 2022

Objectives

Within-subject biological variation (CV

i
) is a fundamental aspect of laboratory medicine, from interpretation of serial results, partitioning of reference intervals and setting analytical performance specifications. Four indirect (data mining) approaches in determination of CV

i
were directly compared.

Methods

Paired serial laboratory results for 5,000 patients was simulated using four parameters, d the percentage difference in the means between the pathological and non-pathological populations, CV

i
the within-subject coefficient of variation for non-pathological values, f the fraction of pathological values, and e the relative increase in CV

i
of the pathological distribution. These parameters resulted in a total of 128 permutations. Performance of the Expected Mean Squares method (EMS), the median method, a result ratio method with Tukey’s outlier exclusion method and a modified result ratio method with Tukey’s outlier exclusion were compared.

Results

Within the 128 permutations examined in this study, the EMS method performed the best with 101/128 permutations falling within ±0.20 fractional error of the ‘true’ simulated CV

i
, followed by the result ratio method with Tukey’s exclusion method for 78/128 permutations. The median method grossly under-estimated the CV

i
. The modified result ratio with Tukey’s rule performed best overall with 114/128 permutations within allowable error.

Conclusions

This simulation study demonstrates that with careful selection of the statistical approach the influence of outliers from pathological populations can be minimised, and it is possible to recover CV

i
values close to the ‘true’ underlying non-pathological population. This finding provides further evidence for use of routine laboratory databases in derivation of biological variation components.

Published: February 2022

Objectives

International guidelines recommend fixed cut-off values for thyroglobulin (Tg). These cut-offs do not take potential assay differences into account. This study aimed to evaluate if different assays for Tg and Tg antibodies (TgAb) affect management guidance for differentiated thyroid cancer (DTC) patients.

Methods

In 793 samples derived from 413 patients with DTC, Tg and TgAb were simultaneously measured with two immunometric assays: Immulite 2000XPi and Kryptor compact plus. In addition, a qualitative measurement for TgAb interference (recovery test) was performed on the Kryptor compact plus platform. The extent to which different assays lead to different classifications of response to therapy was evaluated when applying the current cut-offs for Tg.

Results

Mean Tg concentrations were 37.4% lower with Kryptor as compared with Immulite. Applying guideline based cut-off values for Tg, 33 (4.7%) samples had a Tg-on concentration ≥1.0 μg/L with Immulite and <1.0 μg/L with Kryptor. Of the samples tested as TgAb+ with at least one assay (n=125), 68 (54.4%) samples showed discrepancy in TgAb status. Differences between Immulite and Kryptor measurements resulted in a change in the response to therapy classification in 94 (12.0%) measurements derived from 67 (16.2%) individual patients.

Conclusions

A substantial portion of DTC patients were classified differently dependent on which Tg and TgAb assays are used, when applying the cut-off values as defined in clinical guidelines. Such differences can significantly affect clinical management. In the context of large between-method variation, the recommended Tg cut-offs in guidelines should be used with wisdom rather than as fixed cut-offs.

Authors: Xiong Tao , Zhang Yi-Fu
Published: February 2022

The polycaprolactone diol (PCL diol) was prepared by ring-opening polymerization method, with hydroquinone bis(2-hydroxyethyl) ether as the reactive initiator and ε-caprolactone as the monomer. The polyurethane acrylate (PUA) was prepared with the self-made PCL diol. Then, PUA was used to prepare the ultraviolet curable coatings. The structure and molecular weight of PCL diol was characterized by Fourier transform infrared spectroscopy, gel-permeation chromatography, and hydroxyl value titration. The performance of the cured coating film was characterized by thermogravimetric analysis and scanning electron microscope. The flexibility and hardness of the cured coating film were tested. The results showed that the narrow molecular weight PCL diol was successfully synthesized. The UV curing coating film had the optimal performance with a hardness of 3H, flexibility of 1.5 mm, abrasion resistance of 0.028 g−1, and adhesion of grade 1, all coating films showed good thermal properties.
Effect of photodegradation on fungal colonization on wood during initial stage of brown-rot decay

Published: February 2022

Photodegradation and decay may happen simultaneously on wood under many exposure conditions. The aim of this study was to explore the effect of photodegradation on fungal colonization during initial stage of brown-rot decay of wood. For this purpose, southern pine (Pinus spp.) wood was exposed to accelerated UV weathering for different durations, and then decayed by a brown-rot fungus (Gloeophyllum trabeum). The changes in wood microstructure, chemical composition, surface color, crystallinity, fungal colonization pathways, and photodegradation products after weathering and decay were evaluated and characterized. The results showed that both weathering and decay led to obvious color change on wood surface. The photodegradation of wood resulted in the formation of cracking in cell wall, thus creating new voids. The photodegradation products, which mainly consisted of phenols, diterpenoid acids, and other lignin derived compounds, appeared in the cell lumen. During the initial stage of brown-rot decay, fungal hyphae invaded into wood through inherent voids such as ray cells, axial tracheids, and pits, and completed the initial colonization after 20 days. After photodegradation, hyphae could also invade wood from the new voids, and the acidic photodegradation products promoted the non-enzymatic degradation process of brown-rot. However, lignin derived compounds seemed to inhibit the further activity of decay fungi.
Medical students’ perceptions of understanding skills needed in treating cardiac patients through simulation-based encounters in a clinical skills curriculum
Authors: Mann Brian G. , Obisesan Olawunmi
Published: February 2022

Context

Simulation-based education can enhance medical students’ understanding of clinical concepts as they learn the key elements needed to treat patients with various medical conditions. The integration of simulation programs into medical school curricula increases students’ exposure to this type of learning.

Objectives

To determine the effectiveness of simulation activities on medical students’ perceptions of understanding cardiac rhythm identification and the pharmacology skills necessary to manage a stable patient with cardiac arrhythmia.

Methods

A retrospective secondary data analysis was conducted utilizing a quasi-experimental one-group pretest/posttest study of a convenience sample of 159 second-year medical students in the southeastern United States during the 2017–2018 academic year. Because this was a one-group pretest/posttest study, only second-year medical students whose data could be matched were included. A 5-point Likert scale, previously developed as part of the clinical skills course, was utilized to collect ordinal understanding of cardiac rhythm identification and the pharmacologic management of a stable patient with cardiac arrhythmia. The intervention was an 18-min simulated patient encounter involving a high-fidelity mannequin (SimMan 3G or Essential) with supraventricular tachycardia.

Results

Of the 159 students, the number of students who reported a good perception of understanding of cardiac rhythm identification presimulation activity increased from 44.0% (70) to 52.2% (83) postsimulation activity. The number who reported a good perception of understanding of the pharmacologic management of a stable patient with cardiac arrhythmia presimulation increased from 37.7% (60) to 49.1% (78) postsimulation. A Wilcoxon signed-rank test model was fitted to examine improvements in perceptions of understanding of cardiac rhythm identification and the pharmacologic management of cardiac arrhythmia. The results suggested that participation in simulation activities elicited a statistically significant improvement in the students’ perceptions of understanding of cardiac rhythm identification and the pharmacologic management of cardiac arrhythmia (p=0.000).

Conclusions

As medical education continues to evolve, simulation-based education may be helpful in enhancing medical students’ understanding of cardiac rhythm identification and the pharmacology skills necessary to manage a stable patient with cardiac arrhythmia.
