Authors: Cuong Pham Viet , Hoa Nguyen Phuong
Published: October 2021

The bacteria capable of fixing atmospheric nitrogen were isolated from cassava cultivated soils of Vietnam. The potential isolates were identified by analyzing the 16S rRNA gene and by morphological, biochemical, cultural characteristics. The selected isolates were assigned to the species Bacillus sp. DQT2 M17, Bacillus subtilis DTAN6 M17, and Bacillus megaterium DSHB I8. The effect of culture conditions on the nitrogen-fixing activity of three selected isolates were studied and the obtained results showed that the highest amount of accumulated ammonia was detected after 6 days of incubation at 35 oC, pH 7.0 with sucrose as a carbon source. The selected strains could be exploited as inoculants for microbial fertilizer production.
Biomass production of fungus \(\textit{Termitomyces clypeatus}\) in a stirred-tank bioreactor
Authors: Nhi Nguyen Thi Ngoc , Dung Tran Nhan
Published: October 2021

Termitomyces clypeatus is a fungus species, which has been used as food and medicinal mushroom. In the current study, submersed fermentation of the fungus in a stirred-tank bioreactor was determined for its culture biomass and nutrient contents. T. clypeatus obtained its highest biomass after from 13 to 15 days of cultivation, when the dry biomass of its mycelium system was more than 6%. Agitation speeds of 150 or 180 rpm were the most suitable for the fungus. The determination of chemical compositions showed that the dry biomass of its mycelium system had high protein content, with 57.8% on its dry-weight basis. Besides, 11 types of amino acids higher than 0.1% of wet weight culture were found in fermentation products. Moreover, dried mycelia of the fungus contained 27.4% carbohydrates. The protein and carbohydrate containing in the mycelium and fruit body of T. clypeatus were not statistically different. These results showed that a stirred-tank bioreactor could be applied to culture the fungus.

Evaluation of the condition for storing pollen grains of japanese melon \(\textit{Cucumis melo}\) L. (Cucurbitaceae)
Authors: Dong Phuong Nguyen Tran , Sang Mai The
Published: October 2021

In recent years, studies have been carried on the selection and breeding of melon to reduce its production cost. The F1 seeds of this species are usually created by parental lines. Notably, the parental lines are separated from each other to secure the breeding materials. However, there are no studies on establishing suitable conditions for storing pollen grains of Japanese melon Cucumis melo L. In this study, pollen grains of C. melo were dried at 38 oC temperature, for 1.5 hours, which served as the raw materials. After storage in acetone at 5 oC for 3, 5, 7 days, or in liquid nitrogen for 5 days, pollen grains were stained with triphenyl tetrazolium chloride (TTC) to evaluate their viability and pollination ability. Then, the following parameters including pollen grains’ survival rate, morphology analysis of pollen grains, pollen grains’ fruiting rate, fruit weight, firm seed rate, and germination of melon seeds were analyzed. The study results show that the grains’ survival rates were 86.58%, 88.38%, 87.28% or 88.58% in the group stored in acetone for 3, 5, 7 days or liquid nitrogen for 5 days, respectively. The fertilized fruit rate was 100% in the group stored in liquid nitrogen for 5 days. But the rate of germination from firm seeds was highest, with 94.00% in the group stored in acetone for 3 days. The best method is storing the pollen grains in acetone for 3 days.
Focus projection need not be based on pitch accents: evidence from Georgian
Authors: Borise Lena
Published: October 2021

Based on experimental evidence, this paper shows that the prosodic realization of focus in Georgian is consistent with focus projection/percolation – the phenomenon by which prosodic prominence on a sub-constituent signals focus on a larger constituent – and can be accounted for with a Default Prosody-style analysis. In focus projection in English, object-focus utterances are realized in the same way as VP- or broad-focus utterances, because in all three cases the object carries the nuclear pitch accent. In contrast, in subject-focus utterances, the subject carries the nuclear pitch accent, which is incompatible with broad- or VP-focus interpretation; focus projection does not arise. Unlike English, Georgian, a ‘phrase language’, relies not on pitch accents but on boundary tones and phrasing in focus marking (Skopeteas & Féry 2010; 2016). This language type has not been explicitly addressed from the perspective of focus projection. Nevertheless, the results reported here demonstrate that the prosodic realization of subject- and object-focus in Georgian, expressed with boundary tones and duration of the stressed syllable, fits with the focus-projection pattern. This paper shows that the Georgian data can be accounted for with the Default Prosody approaches to focus projection, but not approaches employing the formal mechanism of F-projection. Accordingly, the Georgian facts provide a novel argument in favor of the Default Prosody approaches.

Esta investigación tuvo como propósito identificar los aportes de la Tecnologías de la Información y Comunicación (TIC) en la enseñanza y el aprendizaje de la Biología en participantes de Olimpiadas Costarricenses de Ciencias Biológicas (OLICOCIBI), particularmente para la potenciación de las habilidades: resolución de problemas, apropiación de tecnologías digitales y responsabilidad individual y social. El estudio realizado es de tipo exploratorio y descriptivo donde se realiza una exploración del uso de las TIC en las aulas de Biología de diferentes instituciones educativas de Costa Rica, donde se utilizan recursos tecnológicos, para abordar y comprender un contenido, al potenciar habilidades. La recolección de la información se llevó a cabo mediante una muestra de 447 estudiantes que participaron en la I fase eliminatoria de las OLICOCIBI, a quienes se les aplicó una encuesta sobre acceso, uso y actividades realizadas con las TIC, mientras en la segunda fase final, se aplicó una encuesta a 90 estudiantes sobre los aportes de las TIC en la potenciación de las habilidades descritas anteriormente. Asimismo, se contó con una muestra de 20 docentes de Biología a quienes se les aplicó una encuesta sobre acceso y uso de TIC, además de los aportes para el desarrollo de estas habilidades. Se concluye que la habilidad que más se potencia es la apropiación de las tecnologías digitales, donde el estudiante logra una mejor comprensión del aprendizaje. Mientras los criterios de las habilidades que son aportados corresponden al reforzamiento de los contenidos y ayudar a encontrar soluciones a problemas que al principio parecían no tener solución, pertenecientes a la habilidad de la apropiación de tecnologías digitales y la habilidad de resolución de problemas, respectivamente. Por tanto, las TIC en la enseñanza de la Biología modifican el modelo tradicional, logrando que los estudiantes avancen a su propio ritmo según sus capacidades e intereses, así como lograr un proceso de enseñanza y aprendizaje más atractivo y significativo. No obstante, la capacitación de las personas docentes es trascendental, debido a que debe existir un uso adecuado de TIC y su incorporación al quehacer educativo.

Authors: Alsaffar Mohamed J.
Published: October 2021

Although there is a wealth of studies on the role of virtual reality (VR) technology in language acquisition, little research has been done on the utilization of virtual reality mobile applications in English language acquisition, especially in developing oral presentation skills. The main purpose of this case study is to investigate the usefulness of VirtualSpeech, which is a virtual reality mobile application, as a preparation tool for oral presentations via the perceptions of international students and their instructor. The participants are five Academic English Program (AEP) students and their English language instructor at Saint Michael’s College. Qualitative analyses were performed on data collected from: (1) learning logs that were shared between the students and the researcher, (2) surveys that were sent to the students and their instructor, (3) one-to-one interviews with the students, and (4) the researcher’s fieldnotes of the students’ oral presentation performances. The results of the study show that all of the participants recommend using VirtualSpeech as a tool to prepare for oral presentations. Most of the students reported higher confidence levels while speaking English after their use of VirtualSpeech. Thus, this case study can be considered as a contribution to the research on VR mobile applications in English language acquisition.

Authors: Liu Yingjie
Published: October 2021

Flipped classroom is not only the flipping of knowledge imparting and knowledge internalization, but also the all-round reform of education concept, teaching content, teaching methods, teaching means and teaching evaluation. Multimodality provides a theoretical perspective and analytical framework for the teaching design of flipped classroom. Multimodality theory fits many characteristics of flipped classroom, which is conducive to giving full play to the advantages of flipped classroom. With the help of multimodal theory and multimodal teaching ideas, this study constructs a flipped classroom teaching mode under the multimodal perspective, which takes the dynamic teaching structure as the core and the open multimodal learning environment as the all-round support, and gives some operational suggestions.

Published: October 2021

An integrated approach including the click chemistry methodology, molecular docking, quantum mechanics, and molecular dynamics was used to computer-aided design of potential HIV-1 inhibitors able to block the membrane-proximal external region (MPER) of HIV-1 gp41, which plays an important role in the fusion of the viral and host cell membranes. Evaluation of the binding efficiency of the designed compounds to the HIV-1 MPER peptide was performed using the methods of molecular modeling, resulting in nine chemical compounds exhibiting high-affinity binding to this functionally important site of the trimeric “spike” of the viral envelope. The data obtained indicate that the identified compounds are promising for the development of novel antiviral drugs, HIV fusion inhibitors blocking the early stages of HIV infection.
Pólen coletado por Tetragonisca angustula em meliponários de zonas urbanas de Curitiba, Paraná
Authors: Ponciano Giuliana Feil , May Dayane
Published: October 2021

Os grãos de pólen coletados por abelhas podem servir de ferramenta para identificação de espécies vegetais, assim como ajudam a esclarecer a relação existente entre polinizadores e a flora local. A presente pesquisa teve como objetivo analisar o perfil botânico do pólen proveniente da abelha nativa Tetragonisca angustula (Jataí) e identificar quais plantas são visitadas por esta. O pólen foi coletado dos potes de alimento de dentro das colmeias presentes nos “Jardins de Mel” de Curitiba, PR, em dois pontos diferentes. As amostras foram preparadas pelo método de acetólise, seguida de montagem e observação de lâminas semipermanentes em microscópio óptico. A identificação taxonômica dos grãos de pólen foi realizada com auxílio de artigos científicos e banco de dados palinológicos. A análise qualitativa resultou na observação de 16 tipos de grãos de pólen, pertencentes às famílias Acanthaceae, Asteraceae, Amaranthaceae, Brassicaceae, Cannaceae, Fabaceae, Loranthaceae, Myrtaceae, Malvaceae, Poaceae e Solanaceae. O pólen identificado teve origem de espécies nativas, corroborando a relação entre a flora nativa e as abelhas sem ferrão. Observou-se uma diferença de riqueza polínica entre os dois pontos de coleta, sugerindo que um deles, a praça General Osório, apresenta pouca diversidade em sua arborização, tendo assim menos opções de visitação para as abelhas residentes desse meliponário.

Published: October 2021

Os Sistemas agroflorestais (SAFs) são sistemas de produção agrícola que atuem próximos a dinâmica da natureza. O objetivo desta pesquisa foi avaliar características químicas, físicas e microbiológicas de solos de SAF’s em três estágios sucessionais e em uma área controle (pastagem), localizadas em Brasília, Distrito Federal. O histórico da área foi elaborado a partir de informações coletadas em entrevista. Realizou-se análises químicas (pH, MO, C, N, C:N, P, K, Ca, Mg e Al), físicas (granulometria) e microbiológicas (glomalina facilmente extraível). Os dados foram analisados através de análise multivariadas e univariadas. A agrobiodiversidade vegetal foi de 19 espécies no SAF estabelecido, 11 no SAF em formação, 5 no SAF inicial e 2 na pastagem. Os SAFs estabelecido e em formação foram os que obtiveram o maior aumento progressivo de C, MO, K e Ca. Quanto maior o estágio sucessional, maior o grau de agregação e a distribuição dos agregados. Os solos de todos os SAFs e da pastagem apresentaram a glomalina, sendo sua maior concentração nos SAFs. Conclui-se que quanto maior o tempo de manejo, maiores serão as diferenças nas características químicas, físicas e microbiológicas do solo. A evolução temporal dos sistemas favorece para uma maior disponibilidade de nutrientes, aumento da atividade biológica e da capacidade de agregação, aumentando, consequentemente, a camada orgânica do solo, retendo mais carbono no sistema, gerando serviços ecossistêmicos e contribuindo para a atenuação dos efeitos danosos de processos agrícolas no solo e no ecossistema.

O objetivo deste trabalho foi avaliar o potencial do óleo essencial de cataia (Drimys brasiliensis Miers) no controle do crescimento micelial do fungo Alternaria porri. Informações sobre novos compostos para o controle deste fungo são importantes pois estes são responsáveis por danos em diferentes culturas como alho e batata. O óleo essencial foi extraído de folhas frescas de cataia, por hidrodestilação. Para a avaliação do efeito do óleo essencial no crescimento micelial do fungo A. porri, alíquotas do óleo foram incorporados no meio de cultura do BDA nas doses de 0 (controle), 100, 250 e 500 ppm. Um disco de meio BDA contendo micélio e propágulos fúngicos, com aproximadamente 5 mm de diâmetro, foi colocado no centro de cada placa de Petri com o meio de cultura BDA, acrescido das diferentes concentrações do óleo essencial. As placas foram seladas e incubadas à temperatura de 25 ºC ± 1, com fotoperíodo de 12 horas, sendo aferidas, diariamente, o diâmetro das colônias. Com os dados de crescimento micelial, calculou-se a Área Abaixo da Curva de Crescimento Micelial e o Índice de Velocidade de Crescimento Micelial. Todos os tratamentos foram estatisticamente diferentes e os resultados indicaram inibição do crescimento dependente da dose, alcançando 55% de inibição a 500 ppm. Além disso, foi observado a redução da velocidade do crescimento fúngico (em cm/h), na dose de 500 ppm em relação ao controle.
Manejo y propagación de la uña-de-gato (Uncaria guianensis y U. tomentosa) en comunidades Tikuna del sur de la amazonia colombiana

Published: October 2021

La uña-de-gato (Uncaria guianensis (Aublet) J.F. Gmel y U. tomentosa (Willd. ex Roemer & Schultes) DC.), empleada en la medicina tradicional amazónica, se destaca por tener propriedades farmacológicas que han generado un interés comercial. Hasta el momento hay una mayor cantidad de estudios sobre el manejo agroforestal y los métodos de propagación de la U. tomentosa; no obstante, es poca la información disponible sobre la Uncaria guianensis, en especial con lo relacionado a su manejo en comunidades. Con el propósito de contribuir con información sobre el manejo de estas especies y de evaluar su propagación vegetativa, se realizaron entrevistas, recorridos de campo y ensayos de siembra en comunidades Tikuna. Se encontró que el manejo de las especies de uña-de-gato, principalmente de la Uncaria guianensis, se centra tanto en las prácticas de extracción y siembra por estacas, así como en su regeneración natural. Igualmente, en los experimentos de propagación vegetativa se evidenció que la Uncaria tomentosa presentó una alta tasa de mortalidad, pues fue más susceptible a los efectos de las condiciones ambientales. Por el contrario, la Uncaria guianensis tuvo una mayor tasa de sobrevivencia, especialmente en bosques secundarios donde se sembraron estacas tratadas con hormonas de enraizameinto y en suelos enriquecidos con abono orgánico. Los resultados obtenidos en este estudio pueden contribuir en la formulación de estrategias de manejo integral, que permitan un uso sostenible de poblaciones naturales de las especies de uña-de-gato en comunidades amazónicas.
Neuroinflammatory State of Multiple Sclerosis and Strategies for Biotherapeutics Development
Authors: Soltanmoradi Samira , Kouhkan Fatemeh , Rad Iman
Published: October 2021

Multiple Sclerosis (MS) is the most prevalent neurological disability in young adults. The pathogenesis of MS is characterized by demyelination and neurodegeneration in the central nervous system (CNS) as the ruinous result of chronic activation of the immune system. All clinical forms of MS, including relapsing-remitting multiple sclerosis (RRMS), secondary progressive multiple sclerosis (SPMS), and the primary progressive MS (PPMS), demonstrate inflammation as a common symptom. In various autoimmune diseases like MS, the ability of the immune system to set a balance between pro-inflammatory and anti-inflammatory responses is lost. In this review, the imbalance between pro-inflammatory and anti-inflammatory responses of immune cells and their role in MS progression is discussed. Disturbing the balance of Th1/Th2 and Th17/Treg cells and M1/M2 phenotypes of macrophages and microglial plays a key role in the development and progression of MS. In this review, we first depict an outline of regulatory immune cells involved in inflammation. Second, we discuss shreds of evidence that confirm how B cells play both pathogenic and protective roles in MS disease. Third, we point out the pros and cons of B cell/T cell-targeted therapies in clinical trials.

Authors: Fallahi Afsaneh , Riahi Leila , Nikravan Aniseh
Published: October 2021

Objective: Falls are the main cause of injuries and death among the elderly and lead to using medical services. This study aimed to assess the effect of falls on medical costs among elderly inpatients.
Methods: This retrospective cross-sectional study was done in a public hospital (heart center) in Qazvin, Iran. In this study, 79 medical records of the elderly who had experienced in-hospital falls and 79 medical records in control group with similar characteristics who had not experienced in- hospital falls during 2016-2019. The data, including the elderly age, sex, fall characteristics, and all hospital costs related to falls were gathered from hospital accident forms, medical records, nursing reports, and official data banks. The overall costs of services provided for fallen elderly were compared with the control group. The data were analyzed by SPSS software, version 22, using Chi-square and paired sample t-test. P<0.05 was considered statistically significant.
Results: Total cost of all services provided for the elderly during their hospitalization was 106.596$ (base year: 2019, $1=42500 IRR), of this amount 8.600$ (8.06%) was related to the services due to in-hospital falls. The highest costs were related to treatment services (40%), diagnostic services (33%), visits (21%) and consultation (6%). The difference between the case and control groups was 7.310$. The elderly falls significantly increased medical costs by 8.06% (P≤0.01).
Conclusions: Even falls that do not lead to serious injuries waste medical services and increase hospital costs by making changes in treatment methods and increasing the length of hospital stay.

Published: October 2021

Recent research has shown that the corporate social responsibility system has a positive impact on consumer behavior regarding products or services that promote social responsibility. Thus, it can be stated that customer loyalty to a particular company derives not only from commercial benefits but also from the components of corporate social responsibilities practiced by the company. The vast majority of company managers in Romania do not understand what it means to be a socially responsible company, which is why they do not even agree with most of the definitions given to corporate social responsibility; secondly, when asked to explain what social responsibility means, they are not able to make logical arguments; I argue that the involvement of companies in social responsibility activities has a purely economic motivation and that it is related to the size of the company, rather large companies integrating the implementation of CSR activities in its vision. From a marketing perspective, corporate social responsibility has proven its ability to generate many benefits for companies, implementing and communicating specific policies and actions in this regard with the potential to improve satisfaction and loyalty, both among customers and of employees.  The main objective of the article is to analyze the way in which consumers in Romania perceive the corporate social responsibility system of companies.
Capitalism with a Purpose: Can Business Ethics Fight Inequality?
Authors: Fioravante Rosa , Del Baldo Mara
Published: October 2021

Economic crises - such as the Great Recession of 2008 or the 2020 crisis triggered by the Covid-19 pandemic - have always represented an opportunity to address the relationship between macroeconomic variables and business and society’s reactions to them. Indeed, negative economic conjuncture, slump and stagnation, represent a challenge and may elicit the opportunity to rethink the role of business in tackling systemic global problems of the current system - such as persisting and raising inequalities and environmental unsustainability – by focusing on Business Ethics both as a theory and a practice. Accordingly, the present work aims at shedding light on the link between the systematic production of inequality within the current economic system and the opportunities for entrepreneurs and managers to significantly reduce it by engaging in business ethics practices. For this purpose, the theoretical framework proposed rests on a step “back” to the discussion of the relation between economic sphere and society, particularly when addressing the issue of value creation/extraction and a step “forward” in the discussion on the purpose of the enterprise and the social role of the entrepreneur. In doing so, three main issues will be addressed: VALUE CREATION - the role of the enterprise in value creation between capital and labour; RESPONSIBILITY - responsible vs irresponsible capitalism; SOCIAL ACTOR - the conception of the enterprise as a social rather than only and economic actor. Bridging perspectives coming from economics, business studies and economic sociology, this paper depicts a robust theoretical and conceptual framework to be used for further empirical research.
Artistic Modelling of History in the Literature and Non-Fiction of a Post-Totalitarian Society

Published: October 2021

An artistic interpretation of historical facts is quite relevant in the literature and non-fiction of a post-totalitarian society. Prose works on historical themes are valuable and interesting in that they create an illusion for readers to be present in a certain period of historical time, and it is the artistic modeling of events that makes priceless facts of history completely disappear. The historical past is an inexhaustible material that word artists have been referring to for centuries, creating the best examples of fiction. Prose texts of historical subjects are perceived by each next generation in a new way, historical events and phenomena are interpreted from different angles, the activities of famous figures of the past are widely covered. Non-fiction literature is a kind of literature that is on the verge of artistry and documentary. The main non-fiction genres are a diary, autobiography, biography, memoirs, confession, letters, etc. On the one hand, non-fiction literature claims to recognize the author’s subjective truth about him in her texts; on the other hand, only the reader can either, demonstrating full confidence in the author, call this text documentary, or admit the presence of poetry and aesthetics in the work and tilt the scales in the direction of artistry. The material for observation and research of the phenomenon of artistic modeling are works that allow us to trace the most common, in our opinion, models of correlation of historical and artistic consciousness in postmodern literature and non-fiction of a post-totalitarian society.

Published: October 2021

A nation cannot exist without national culture and national self-consciousness. These concepts are decisive in the development of the nation. Values are the priorities of any nation, determined by its culture and self-awareness. The national cool is the basis for the formation and development of national self-consciousness. The aim is to analyze the influence of national culture on the formation of national consciousness. Justify their objective and subjective factors of formation, which are based on the motivational core of personality behavior. National culture and national self-consciousness are the main features of a nation, without which it cannot exist and develop as a whole. National culture and national self-consciousness are one whole of the spiritual world of nations and nationalities. The development of national culture and national self-consciousness is an objective regularity. Naturally, contradictions in this process will exist and demand their resolution or escalate into conflicts. With a timely solution, they will play the role of an indicator of national development.
Society Ladenness Model: System-Parametric Analysis
Authors: Nerubasska Alla , Paulava Volha , Bogachenko Valentyna , Lopuha Oresta
Published: October 2021

The system-parametric method developed by A. Uyemov allows creating a model of the contemporary bifurcational reality. There are many terms adopted from other sciences which are often used in postmodern philosophy. Bifurcation is one of such terms adopted from synergetics. In this article emphasis is placed on the contemporary time which is bifurcational in its essence. Using the key thesis of the systems method which states that any object can be presented as a system, we propose to create a model of social ladenness. The mere fact that ladenness exists, makes the system of crisis (bifurcation) nature. The social ladenness is defined using system descriptors. This definition contains the concept, the structure, and the substrate of the object and analysis of their elements. Consistence and hierarchical arrangement of the descriptors is the social ladenness model under discussion. The elements identified in the social ladenness model are the economic, political, technical, ecological, religious, creative and bifurcation impact. We identified some markers of human existence in the community system. The coronavirus pandemic is used as an example to demonstrate the way the bifurcation society system model can be built in order to find solutions to overcome the social and individual crises.
A Linguistic and Philosophical Analysis of Anthropological Paradigms

Published: October 2021

The article justifies the need to involve philosophy in specific scientific research due to the ineffectiveness of verbal-and-figurative models and the inadequacy of character education. Indeed, philosophy can increase their theoretical and applied effectiveness in the long-term methodological perspective. The article shows the wrong side of limitations in specific scientific research imposed by an interdisciplinary methodology. It points out to the disadvantages of applying interdisciplinary methods in psycholinguistics, such as analysis synthesis, induction and deduction. The article expands the range of their understanding to achieve a higher level of reliability. Besides, it proves the inadequacy of conclusions obtained mainly from superficial empirical studies without revealing and analyzing their main causes, it being a violation of the determinism principle. It substantiates the need to comply with methodological principles of objectivity and systematicity while analyzing the concepts of the humanities block. If one ignores these principles, it can lead to eсlecticity and, hence, the inefficiency of specific scientific research. The effectiveness of methodological principles in psycholinguistics is shown through a consistent analysis of freedom as a philosophical category, as well as a gradual analysis of the links between such concepts as freedom - responsibility, freedom - arbitrariness - responsibility, freedom - interest - arbitrariness.

The article reveals the issues of interdependence of the development of human capital in public administration on the level of its provision by the state in the context of COVID-19. In a democratic, civil, postmodern society, one of the main tasks is the development of systems for managing the efficiency of human capital in the context of public administration, as a means of obtaining higher levels of labor productivity. Today we have to state that the achievement of this efficiency in the use of human resources can be better achieved by orienting the performance management system to promote the attraction of new human potential in public administration at all levels. In this context, a new approach to the human capital management process is being actualized, which includes employee engagement and key factors of employee engagement at every stage. We are talking about a management model that includes the main ideas and offers a new perspective on how to develop and manage the involvement of human resources to achieve high levels of labor productivity in public administration in the context of COVID-19. The purpose of the article is to study the essence, characteristics and role of human capital in the context of public administration in the context of the existence of the epidemic danger of COVID-19

Objective: This study examines gender and socioeconomic inequalities in parental psychological wellbeing (parenting stress and psychological distress) during the COVID-19 pandemic in Germany.

Background: The dramatic shift of childcare and schooling responsibility from formal institutions to private households during the pandemic has put families under enormous stress and raised concerns about caregivers' health and wellbeing. Despite the overwhelming media attention to families’ wellbeing, to date limited research has examined parenting stress and parental psychological distress during the COVID-19 pandemic, particularly in Germany.

Method: We analyzed four waves of panel data (N= 1,771) from an opt-in online survey, which was conducted between March 2020 and April 2021. Multivariable OLS regressions were used to estimate variations in the pandemic's effects on parenting stress and psychological distress by various demographic and socioeconomic characteristics.

Results: Overall, levels of parenting stress and psychological distress increased during the pandemic. During the first and third wave of the COVID-19 pandemic, mothers, parents with children younger than 11 years, parents with two or more children, parents working from home as well as parents with financial insecurity experienced higher parenting stress than other sociodemographic groups. Moreover, women, respondents with lower incomes, single parents, and parents with younger children experienced higher levels of psychological distress than other groups.

Conclusion: Gender and socioeconomic inequalities in parents' psychological wellbeing increased among the study participants during the pandemic.

Published: October 2021

A degradation assessment technique based on an online improved symbol sequence entropy online_ISSE and a logistic regression model is proposed in this paper. Firstly, the threshold factor is introduced to retain the `coarse graining' information of direction changing and amplitude information, the `sensitivity' of improved symbol sequence entropy (SSE) to impact components is reduced and improved symbol sequence entropy (ISSE) is proposed. Then, a sliding window and Weibull distribution theory are used to effectively filter out the influence of fluctuations in the ISSE feature sequence, forming the degradation feature named online_ISSE. Finally, a logistic regression model is trained and constructed, and the health factor CV is calculated online to assess the degradation condition of the unknown signal samples. The lifetime vibration signal of the hoisting gearbox monitored from #8114 quay crane of the Shanghai Port Container Terminal is introduced for instance analysis. The results show that the proposed ISSE has a better effect in describing the complexity pattern than the SSE algorithm and that the degradation condition can be tracked and assessed accurately based on the technique proposed.
A Recursive Legendre Polynomial Analytical Integral Method for the Fast and Efficient Modelling Guided Wave Propagation in Rectangular Section Bars of Orthotropic Materials
Authors: Zhang Xiaoming , Shao Shuangshuang , Shao Shuijun
Published: October 2021

Ultrasonic guided waves are widely used in non-destructive testing (NDT), and complete guided wave dispersion, including propagating and evanescent modes in a given waveguide, is essential for NDT. Compared with an infinite plate, the finite lateral width of a rectangular bar introduces a greater density of modes, and the dispersion solutions become more complicated. In this study, a recursive Legendre polynomial analytical integral (RLPAI) method is presented to calculate the dispersion behaviours of guided waves in rectangular bars of orthotropic materials. The existing polynomial method involves a large number of numerical integration steps, and it is often computationally costly to compute these integrals. The presented RLPAI method uses analytical integration instead of numerical integration, thus leading to a significant improvement in the computational speed. The results are compared with those published previously to validate our method, and the computational efficiency is discussed. The full three-dimensional dispersion curves are plotted. The dispersion characteristics of propagating and evanescent waves are investigated in various rectangular bars. The influences of different width-to-thickness ratios on the dispersion curves of four types of low-order modes for a rectangular bar of an orthotropic composite are illustrated.

Published: October 2021

This paper presents a smart wind turbine blade of piezoelectric material. Based on Theodorsen unsteady aerodynamics and the V-g method, the flutter analysis in frequency domain is carried out for the smart wind turbine blade and the ordinary wind turbine blade. The simulation results demonstrate that the flutter critical velocity, that is, the reduced velocity of the smart wind turbine blade, is obviously much higher than that of the ordinary wind turbine blade. The smart wind turbine blade of piezoelectric material can effectively restrain the flutter of the wind turbine blade, especially for the flap motion. For the torsion motion, the smart wind turbine blade is kept away from the critical flutter. Then, to investigate the influences of different parameters on the flutter of the smart wind turbine blade, the influences of the center of gravity, the frequency ratio and the mass ratio of the blades on the flutter critical velocity of the smart wind turbine blade are researched respectively. The increase of the applied external electrical load of the piezoelectric material can increase the flutter critical velocity of the smart wind turbine blade.

Introduction: There are unique technical and management challenges associated with living donor liver transplantation (LDLT) for Budd-Chiari Syndrome (BCS). The outcomes of LDLT for BCS in comparison to other indications remains unclear and warrants elucidation. Methods: Data of 24 BCS patients who underwent LDLT between January 2012 and June 2019 were analyzed. There were 20 adults and 4 children. The early and long-term outcomes of adult LDLT BCS patients were compared to a control group of LDLT patients for other indications and matched using propensity scoring methodology. Results: Primary BCS was observed in 22(91.7%) patients. Caval replacement was performed in 7(29.1%) patients. Early and late hepatic venous outflow tract (HVOT) complications were seen in 1(5.5%) and 3(16.7%) patients. Preoperative acute kidney injury was identified as a risk factor for mortality in the BCS cohort (p =0.013). On comparison, BCS recipients were younger with fewer comorbidities, more large volume ascites and higher rates of PVT. They also had longer cold ischemia time, increased blood loss and transfusion requirements, increased hospital stay, and higher late outflow complications. The 1-year and 3-year survivals were similar to non-BCS cohort (84.2% vs 94% and 70% vs 91.9%, respectively, log rank test p=0.09). Conclusion: LDLT is remains a good option for symptomatic BCS who have failed non-transplant interventions. The clinical and risk factor profile of BCS recipients is distinct from non-BCS recipients. By following an algorithmic management protocol, we show on propensity-score matched analysis that outcomes of LDLT for BCS are similar to non-BCS indications.
