Prediction of corrosion rates of a ship under the flow accelerated corrosion mechanism
Authors: Liu Yingwei , Liu Haodian
Published: July 2021

In order to reveal the corrosion of a ship hull in flowing seawater, which is difficult to study under experimental conditions, a numerical method was adopted. Firstly, the numerical model of seawater flow field around the hull was established and computed, and the hydraulic characteristics of the flow field such as velocity, pressure, and oxygen concentration distribution were got. The distribution of oxygen has a great influence on corrosion. Generally speaking, where the oxygen concentration is higher, the corrosion rate is higher. The results show that the oxygen concentration is higher at the rear of the hull bottom surface. Next, a corrosion model was founded based on the above calculation. Through the calculation of the corrosion model, the mass transfer coefficient and corrosion rate distribution on the hull surface were obtained and the final conclusion was got flow accelerated corrosion (FAC) mechanism was revealed. The conclusion is as follows: Comparatively speaking, the corrosion rate of the middle and rear part of the bottom and the middle part of the sideboard is higher. Generally speaking, the corrosion rate increases with the increase of flow rate.
Insights into structure, affinity, specificity, and function of GAG-protein interactions through the chemoenzymatic preparation of defined sulfated oligohyaluronans
Authors: Schiller Jürgen , Lemmnitzer Katharina , Dürig Jan-Niklas , Rademann Jörg
Published: July 2021

High amounts of glycosaminoglycans (GAG) such as hyaluronan (HA) occur in connective tissues. There is nowadays increasing evidence that a “sulfation code” exists which mediates numerous GAG functions. High molecular weight and inhomogeneity of GAG, however, aggravated detailed studies. Thus, synthetic oligosaccharides were urgently required. We will review here chemoenzymatic and analytic strategies to provide defined sulfated and anomerically modified GAG oligosaccharides of the HA type. Representative studies of protein/GAG interactions by (bio)chemical and biophysical methods are reported yielding novel insights into GAG-protein binding. Finally, the biological conclusions and in vivo applications of defined sulfated GAG oligosaccharides will be discussed.
Kinetic studies of 5-(hydroxymethyl)-furfural formation and change of the absorption at 420 nm in fruit juices for the improvement of pasteurization plants
Authors: Katsch Linda , Methner Frank-Jürgen , Schneider Jan
Published: July 2021

Preservation of juices is essential to obtain microbial safe products. There are various established methods as pasteurization. Heretofore, only the kinetic figures of microbial inactivation were considered but not those of reaction impairing the chemical quality. For a gentler processing, knowledge of the kinetics of relevant chemical conversion reactions is necessary. 5-(Hydroxymethyl)-furfural (HMF) formation and the color change of juices are important attributes. The non-isothermal Rhim method was used to determine the activation energy and pre-exponential factor for HMF formation in different juices and an isothermal method for the reaction order. Values for the activation energy from 133 to 303 kJ/mol were obtained with a zeroth reaction order. A correlation between HMF and the color change could be found. Based on the kinetic figures, lines with equal effects for the chemical changes and for the lethal effect on microorganisms were calculated. Time-temperature settings for the gentlest treatment could be found.

Authors: Xue Yahong , Xu Qianqiu
Published: July 2021

The COVID-19 pandemic, as a public health emergency of international concern, is the most extensive one to afflict humanity in this century and poses a grave threat to human life and health. Facing this unknown, unexpected and devastating disease, China makes an all-out effort to fight against it shoulder to shoulder with the rest of the world. Based on the ecosophy of “diversity and harmony, interaction and co-existence” and with ecolinguistic appraisal system as the theoretical framework, this study provides an ecological discourse analysis of news coverage of COVID-19 in China in The Times and The New York Times, two major Western mainstream media outlets, aiming to reveal the appraisal characteristics and ecological orientations of the news coverage on this public health emergency as well as the attitudes of the two major Western mainstream media outlets concerned towards China’s fight against COVID-19, thus helping people to understand the news discourse on this major public health emergency and in turn to distinguish different media positions. It is found that both news outlets employ more negative appraisal resources to express their attitudes towards China’s fight against COVID-19 and their news coverage is to a greater extent eco-destructive.
International Financial Centers as a Model: Facilitating Growth and Development by Connecting to International Legal Frameworks
Authors: Ku Charlotte , Morriss Andrew
Published: July 2021

International financial centers (IFCs) provide means of strengthening law and regulation not only in the financial sector, but also in global governance more broadly and the contribution their legal regimes make to economic development. By demonstrating how ideas move across jurisdictions and how cross-jurisdictional structures add value, IFCs facilitate transactions in jurisdictions where local legal systems and services are not yet adequately developed or available to support economic activity. They serve as regulatory capacity builders, building networks of professionals, regulators, and judges contribute to ongoing innovation and capacity building. Their success at building legal regimes that add value and which are available to new classes of individuals and firms around the world makes them a model for using the legal system to foster economic development.
Voluntary Association Involvement and Political Participation in South Korea
Authors: No Won , Han Hyunrang , Wang Lili
Published: July 2021

While studies suggest that voluntary association involvement leads to more political participation in the U.S. and European countries, the relationship remains debatable in new democracies. Using the Current Social Integration Survey from 2015 to 2018 in South Korea, this study examines the relationship between voluntary association engagement and participation in political activities based on the social capital theory and explores whether the results vary by the types of voluntary associations and multiple memberships in the associations. The results suggest that memberships in voluntary associations are positively associated with voting and engagement in political activities. Additionally, only memberships in certain types of associations are related to voting and engagement in political activities.
Chemical removal of m-cresol: a critical review
Authors: Yang Yi , Li Xiyi , Zhu Huiqi , Xu Xuhui , Bao Lulu
Published: July 2021

m-Cresol containing wastewater has generally become a globally environmental issue due to its refractory and high toxicity towards plants, animals and human being. The development of m-cresol related industries increases the risk of excessive m-cresol discharge, making high efficiency methods to treat m-cresol an urgent topic in both economic and environmental aspects. This review focuses on the chemical treatment methods of m-cresol wastewater, including chemical adsorption, photocatalytic degradation, electrocatalytic degradation and catalytic wet oxidation. The efficiency, cost and process optimization of different methods are discussed in detail. Chemical adsorption is convenient but has relatively low efficiency. Photocatalytic degradation is an easily operated technology with high efficiency, but the selection of catalyst is too limited and the cost of light source is relatively high. Electrocatalytic degradation is time-saving but energy-intensive, and operational difficulty brings a barrier to industrialization. Catalytic wet oxidation (CWO) is highly effective and easily modified, but the performance and stability of catalysts are still very moderate. Following this, the selection and application of different methods regarding the requirement of actual environment are analyzed. Finally, a perspective on the opportunities and development for efficient m-cresol removal method is given.

Authors: ÖZBEK YAZICI Sercan
Published: July 2021

The object of this study is to determine the best solvent and optimum extraction conditions for extraction of maximum phenolic compounds from Alchemilla vulgaris leaves. Extractions were carried out using solvents with different polarities. Box-Behnken Design was used to optimize extraction conditions including extraction time, temperature, and liquid/solid ratio. In the study, extract obtained with acetone-water indicated the highest total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity. Optimum extraction conditions for both responses were found as 168 min, 48.5 °C, and liquid/solid ratio of 41:1. The maximum TPC and TFC values were determined as 7.17 mg GAE/gdw and 3.63 mg QE/gdw under optimum extraction conditions. Concentrations of five phenolic compounds analyzed by HPLC increased significantl after optimization. The results indicated that optimizing extraction conditions is critical for quantification of phenolic compounds. The present model can contribute to food industry where phenolic compounds have potential use as biopreservatives.
Upscaling Downtown: Interpersonal Dynamics of Nightlife Revelers in Geneva, New York
Authors: Sudduth Chloé
Published: July 2021

Bars have long been recognized as the intersection of a city’s culture and commerce. They provide opportunities for social interaction, contain a multitude of local memories, and serve as sources of identity. The American Revolution, the Whiskey Rebellion, and the Stonewall riots all developed out of local bars. So, what does it mean when the character of bars in a neighborhood begins to change? How do these changes to commercial spaces affect the social fabric of a city? Using a combination of ethnographic fieldwork and interviews, I explore the upscaling of the downtown bar scene in Geneva, New York to unpack what these commercial changes mean for the disparate groups that frequent the downtown space. I argue that instead of simply diversifying the types of businesses available to consumers in Geneva, this development has altered the very character and social fabric of downtown. Rather than creating an integrated and cohesive nightlife scene in which disparate groups come together in shared space and time, this development manifests in the fragmentation of the downtown scene in new ways that increase the segregation of people in social space.
Influencias del neoliberalismo en la construcción de la identidad del profesorado en el contexto de la reforma universitaria en el Paraguay
Authors: Giménez Duarte Francisco Javier
Published: July 2021

Este trabajo tiene como propósito una revisión teórica respecto de las características que configuran la identidad profesional del docente en el Paraguay desde algunos rasgos del neoliberalismo identificados en las reformas de la educación superior universitaria en América Latina y que incidieron en los distintos documentos de las políticas públicas nacionales que se implementaron en el subsistema universitario. Se identifican elementos claves del neoliberalismo en la construcción identitaria del profesor universitario que condicionan el ejercicio de su profesión y atentan contra su libertad de cátedra. Se concluye que los elementos neoliberales que estructuran las políticas públicas y desde los cuales se construye su identidad, contradicen las declaraciones fundamentales, los deberes y derechos y, particularmente, los fines de la educación establecidos en la Constitución Nacional.

Temperature’s effect on color change and mechanical properties of poplar powder compact formed by warm compaction
Authors: Zhang Liqiang , Long Zhizhong , Tan Zhili , Wu Qingding
Published: July 2021

Warm compaction technology is an eco-friendly method to improve the added value of poplar. In this work, the wood powder was compacted in the mold between 120 °C to 200 °C, at 80 MPa for 30 min. The color change, chemical properties, and mechanical properties were evaluated. The color of the formed compaction darkened uniformly. The CIE lightness color coordinate (L*) and chroma coordinates a* and b* decreased with the increase of forming temperature. Fourier infrared spectral analysis showed degradation of carbohydrates, along with the formation of a new chemical structure of darker color. Mechanical properties including modulus of rupture (MOR) and modulus of elasticity (MOE) of compacted wood increased initially and then decreased. These results provide a reference for the surface color control of thermally forming materials.

Different biomass sources (bamboo, rape straw, lignin, and Yaupon holly) were liquefied using microwave energy to produce biopolyols, which were then used to prepare biofoams without any further separation process. The results indicated that the content of hydroxyl groups in biopolyols derived from different biomass sources was sorted in descending order as rape straw, Yaupon holly, bamboo, and lignin. The rheological analysis demonstrated that the biopolyols were pseudoplastic, and the yield stress of biopolyols was remarkably increased with increasing biomass content. The compressive strength of polyurethane (PU) foam was rendered smaller by introducing biomass sources. Nevertheless, the biofoam obtained from biomass sources with higher hydroxyl groups content had better PU performance. In addition, the termite resistance performance of PU foam increased with the introduction of Yaupon holly, rape straw, and bamboo sources. Accordingly, the biofoams derived from the liquefaction of rape straw performed better than those from other biomass sources.

The study examines the morphological changes that occur in brain of SHR rats on the background of developing hypertensive dyscirculatory encephalopathy (DE), complicated by chronic alcohol intoxication (CAI). CAI has been proven to potentiate the progressive aging of brain in rats with hypertensive DE by aggravating its course and to lead to the development of DE of mixed genesis. The effectiveness of a single and combined use of rhythmic craniocerebral hypothermia (rCCH) and the introduction of cryopreserved cord blood nucleated cells (cCBNCs) to reduce the progressive vascular lesions of brain and the effects of chronic ischemia in animals with DE of mixed genesis. It has been proven that the combined use of rCCH and cCBNCs in the rats with a mixed DE had a more pronounced positive effect on morphological structure of brain tissues and vessels than their single use. There was a further decrease in the signs of dystrophic, destructive and pathologically altered compensatory adaptive processes in brain on the background of a significant decrease in neuroglial index, stimulation of angiogenesis, complete or partial absence of signs of smooth muscle cell hyperplasia, acute hemorrhages and ischemic strokes, spasms of arterial vessels’ walls and plethory in veins, that contributed to restoration of brain microhemocirculation and cytoarchitectonics.

Published: July 2021

The recent rise of antibiotic resistance and lack of an effective vaccine make the scenario of shigellosis alarming in developing countries like Bangladesh. In recent years, our group reported the vaccine efficacy of a non-pathogenic Escherichia albertii strain DM104 in different animal models, where an ocularly administered vaccine in the guinea pig eye model against Shigella dysenteriae type 4 challenge showed high protective efficacy and also induced a high titer of serum IgG against S. dysenteriae type 4 whole cell lysate (WCL) and LPS. In this study, we report further evaluation of the non-invasive and non-toxic environmental strain DM104 as a vaccine candidate against S. dysenteriae type 4 in mice model. Oral immunization of live DM104 bacterial strain demonstrated better protective immunity in mice model by showing 90% protection in mice against live S. dysenteriae type 4 lethal dose challenge and by inducing effective humoral and mucosal immune responses.

Mass Migration as a Hybrid Threat? – A Legal Perspective
Authors:   Canberra Law School (Australia), Bachmann Sascha-Dominik
Published: July 2021

Migration as a weapon sounds like a policy statement by resurgent nationalistic parties (and governments) in the West. However, politics and the human cost aside, what if an adversary (both state and non-state actor) does exploit the current global crisis of mass migration due to globalization, war, and political unrest? This article will look at the ongoing mass migration to the European Union within the wider security context of the so-called hybrid threats and/or ‘grey zone’ tactics. It looks at the various legal categories of migration as how the law can be weaponized as so-called ‘lawfare’ to undermine the existing legal frameworks distinguishing between legal and illegal migration. The authors recognize the possibility that this article will be used as an argument by the political actors involved for their nationalistic and anti-migration politics and policies. Yet, we believe that the potential of abusing the current vacuum for political gains along ideological party lines makes it necessary to provide a wider legal-security focused perspective on mass migration.
Public Security and Public Order – Conceptual and Institutional Scope

Published: July 2021

The publication aims to analyze public security and public order in conceptual and institutional terms as an analytical category of security sciences. The legislator defines neither public security nor public order. So far, they have been treated mainly as categories of administrative law. It is therefore important to assign them analytical content in the new scientific discipline. The research results allowed for the presentation of the thesis that public security and public order are mainly connected with protection against pathological phenomena occurring in the public space, which are minimized by institutions established to ensure it. These categories should constitute the research field (subject) of the security sciences. The research problem formulated in the form of the question: How are public security and public order treated in definitional and institutional terms? The problem was solved based on a critical analysis of the literature. The paper uses theoretical research methods, including analysis of literature and phenomena occurring in society and inference – as a cognitive factor of the subject of analysis. A critical analysis of the literature on this issue played a large role in the cognitive process.
The principle of similars and importance of arsenic compound as a preventive against Covid-19
Authors: Ghosh Shrabani , Sarkar S C , Mondal Bholanath , Chaudhuri B K
Published: July 2021

In homeopathy, special importance is attributed to the Law of Similars (SimiliaSimilibusCurentur, or “let likes be cured by likes.”). But an in- depth analysis of this principle is still necessary and important for exploring the science behind diluted homeopathic medicine (or Homed).Recently it has been suggested that Arsenicum album 30 (prepared from arsenic compound) might be a curable preventive medicine against Coronavirus infections. But the recommendation for the use of Arsenicum album 30 or similar other medicines as a preventive against Covid-19 are not beyond doubt as this preventive has not been scientifically supported. This is mainly due to the unknown mechanism of the said principle of Similars. The symptoms in this principle are viewed as direct manifestation of the diseases to be cured. There exists close relation between the mechanisms of curing diseases by the Homed and the body’s self healing (or homeostasis related to T-Cells) which is stimulated by Homed to cure the disease. We find incipient quantum mechanical background of this principle and attempted to justify the use of Arsenicum or similar other medicine against Corona infection based on this principle. The principle of Similars has quantum biological foundation arising from quantum coherence (QC)between the ionic charges around the diseased cell and the carrier of diseased cell and those associated with the medicinal agent present in the Homed termed as NAM (H- bonded nano and micros clusters).This principle justifies the use of Arsenicum against the Corona infection. It is demonstrated that the principle of Similars has a deeper incipient meaning rooted to the quantum mechanics. This principle is competent to explain many salient features of homeopathy.
Edu-Psychology: An Insight into Effective Learning
Authors: Dey Ruchira , Chakraborthy Mehuly
Published: July 2021

Education and psychology are interdependent. While the purpose of education has always been imparting knowledge, Psychology has, all through, played a vital role in changing the spirit of it. It has changed the old concept where only upper class had the ability and right to learn, thereby
giving education the theory of individual differences that every child has different mental ability and learns with different pace. Educational psychology has thus formed the basis of education today. It has affected education in every field of teaching and learning process. For years, educators
have written about the purposes, aims, and goals of educational psychology and have stressed the relevance of the field for the practice of the same. However, educational psychologists seem to be having more and more trouble explaining to educators what they do and why educators should care.
This paper, therefore, explores the relevance of educational psychology, noting how it contributes to the preparation of both intelligent quotient as well as the emotional quotient of an individual.
Learning Language through Interactive Language Laboratories: An ESL Perspective
Authors: Moharana Jyoshnamayee
Published: July 2021

English is taught as a second language in India but it is widely used in the length and breadth of the country. The English curriculum is highly text based which focuses on the writing skills. This results in the poor speaking skills of the students in English. Good communication skill
in English is the need of the day. The students need to be given enough exposure in the natural atmosphere to practice English communication skills. With the advent of technology this has become very easy. The language laboratories provide various interactive activities in the audio-visual
mode that attracts the attention of the students and keep them engaged in learning the language in a natural atmosphere. The educational institutes should provide this facility to the students to help them enhance their language skills. This paper discusses the advantages and disadvantages
of the language labs and compares the facilities of various language lab softwares.
Learning by Doing : A Systematic Review on Second Language Acquisition Corresponding to Personality Traits
Authors: Tripathi Mrs. Malabika , Dutta Ria , Roy Akanksha , Sah Malvika
Published: July 2021

INTRODUCTION:Considering the significant amount of world population, there is a huge section of people who are bilingual or multilingual. On the other hand, many people do not have the knowledge or understanding of second language. Personality traits and along with individual differences play a huge role in second language acquisition. Every individual is unique and hence their way of learning or developing a completely new skill varies significantly.OBJECTIVES:The objectives of this paper were to explore how Second Language Acquisition (SLA) is related to various personality traits and to explore this relationship in terms of bi-directional link between the two.METHOD:The method of literature review was employed.FINDINGS:The findings of the present study indicate personality traits, motivation levels and perception of one’s self, other native speakers and of the language have a bi-directional relationship with SLA. Every individual approaches the SLA process differently and has a different success rate with it. It has also been hypothesised that music aids in understanding sound structure and in turn facilitates SLA. We further discuss how socio-cultural factors may play a role here.CONCLUSION:One of the main points that can be drawn from the present study is that SLA is mainly a matter of perception i.e., it is dependent on how an individual choses to view it. According to the demands of the 21stcentury, more language-oriented activities should be incorporated to make second language learning (SLL) an intellectually stimulating process. Additionally, we believe that there exists a bi-directional relationship between personality traits and SLA. Future directions for future researches are also suggested.

Published: July 2021

Kalighat’s paintings originated in West Bengal, India in the 19th century, near Kalighat Kali Temple, in Calcutta, India, and and from being souvenir pieces taken by visitors to the Kali Temple, the paintings developed over a period of time as a distinct Indian form of painting
and art. The Kalighat Paintings developed to depict a range of themes ranging from mythological characters to depictions of the social scene. The paintings served as a kind of mirror of the society in which they worked. Under the influence of an increasingly growing European society, they
underwent a transformation. They were able to rapidly adapt the interests of then popular interest and reflect different contemporary themes., and to represent different contemporary themes. The charm of the Kalighat paintings lies in the fact that they captured the essence of everyday life
and have inspired contemporary artists like the late Jamini Roy even to this day. Experts find the brushwork on these paintings to be precise, flawless, elegant and one of India’s smoothest art types.

Published: July 2021

Background: The genus Quercus has a keystone role in the temperate forests in the northern hemisphere; thus this offers an interesting opportunity to use it as a model to know altitudinal species richness patterns which could be used in further studies and projects in biodiversity conservation. Questions: It is possible to detect an altitudinal gradient based on the genus Quercus distribution? What climatic variables are most important in the altitudinal distribution of the genus Quercus ? Study site: The physiographic province of Sierra Madre del Sur (SMS) located southwest of Mexico. Methods: Based on 3,267 herbarium registers of 61 species, a data matrix was created with the presence/absence of each species in altitudinal intervals of 100 m. Then a similarity matrix was obtained using the Sorensen-Dice index in the R software. Through a discriminant analysis, we evaluated for environmental differences among the altitudinal zones previously obtained through a cluster analysis. Results: We found three altitudinal zones, each one defined by exclusive species, and two important species turnover points. The species richness distribution showed a hump-shaped pattern along the altitudinal gradient. The overall model was highly significant, evidencing the existence of different temperature and precipitation regimes throughout the altitudinal distribution of oaks species in SMS. Conclusions: The altitudinal distribution of oak species in the SMS is not homogeneous and is restricted mainly due to differences in the precipitation and temperature regimes. The altitudinal distribution pattern found in this study could be explained considering ecological and historical factors.
Dewesternising the South African social security law: a leap towards an Afrocentric legal curricular

Published: July 2021

SUMMARY Recent calls to dewesternise the curricular are especially pertinent to the teaching of Social Security Law in South Africa, which has traditionally been dominated by the Eurocentric canon. This article argues that South African Social Security Law is a western-centric phenomenon and dewesternising it is necessary for the decolonisation of legal education. On this score, it provides a critique of the South African Social Security Law in search of pragmatic ideas that can advance the project of decolonising it and creating Third World perspectives. The article unsettles the dominant Eurocentric model on the origin of South Africa Social Security Law which marginalise the role that indigenous knowledge play in the development of this area of law. It argues that placing indigenous knowledge systems on the epicentre of the historiography of teaching South African Social Security Law will lead to some epistemic disruption of the current historic paradigm, a project necessary for the decolonisation of the legal mind and intellectual landscape. The article re-contextualising the orthodox social security theory in the historical scene of colonial and post-era; constructing alternative social security historiography; offering an Africanised dialogue on the origins of the informal strands of social security law; the elaboration of alternative methodologies of actualising the constitutionally protected right to have access to social security. The paper also contends with concepts and ideas such as the deemed trans-colonial importation of social security origins, decolonial philosophy as an epoch of transforming legal education in the context of South African Social Security Law.

La Gestión Empresarial, al igual que otros ámbitos organizacionales, se encuentra en constante evolución, motivado por los cambios científico-tecnológicos y dinámicas empresariales. En la actualidad, encontramos que las organizaciones se enfrentan a escenarios cada vez más complejos y cambiantes que requieren del uso intensivo de datos, información y conocimientos en todos sus procesos, especialmente aquellos que tienen que ver con las actividades estratégicas como son los procesos de Investigación, Desarrollo e Innovación. Esto conlleva para las organizaciones el diseño, desarrollo, despliegue y mantenimiento de modelos de gestión avanzados, que aseguren la competitividad tanto a nivel local, como regional e internacional. En este sentido, el presente trabajo busca analizar la gestión de la Investigación, Desarrollo e Innovación en el área de la Gestión Empresarial dentro de las Organizaciones, a través del uso de técnicas y herramientas bibliométricas, como son los mapas científicos usando SciMAT. Para ello, todos los documentos disponibles entre 2015 y 2019 que guarden relación con estas áreas se recabaron de la base de datos Scopus, a fin de identificar las principales temáticas y su evolución, así como los autores, organizaciones, países y fuentes más productivas. Finalmente, este análisis establece un marco de referencia que permite a las organizaciones aumentar su competitividad a través de una metodología de mejora continua de la Investigación, Desarrollo e Innovación de la Gestión Empresarial.

Published: July 2021

El trabajo es una de las actividades humanas más relevantes de la vida, produce efectos sobre las personas y las organizaciones. Se ha incitado desde los organismos internacionales hacía los países a tomar resguardos respecto no sólo de la seguridad física sino también en lo que refiere a lo psicosocial en los/as trabajadores/as. En Chile, desde el año 2013, se aplica el Protocolo de Vigilancia de Riesgos Psicosociales en el Trabajo para las distintas organizaciones laborales. En este artículo se da cuenta de los riesgos psicosociales de socios/as trabajadores/as de seis cooperativas de trabajo, en un estudio mixto, se observa que en los resultados a nivel cuantitativo las organizaciones obtienen en 4 de las 5 dimensiones un riesgo bajo (exigencias psicológicas, trabajo activo, apoyo social en la empresa y compensaciones), mientras que en la dimensión de doble presencia obtienen un nivel de riesgo alto. Al vincular los resultados con el análisis cualitativo, se obtienen antecedentes que permiten comprender que las prácticas de gestión cooperativa estarían influyendo de manera compensativa respecto de otros riesgos psicosociales presentes.
Research of Interactive and Traditional Tasks Aimed at Studying Information Technologies among Students
Authors: Popkov S.I.
Published: July 2021

The results of a study conducted within the framework of an interactive approach to the task formation, which is an actual branch of computer methods in education, are presented. The author notes that the branch is currently not used for teaching information technologies practice in higher educational institutions due to the labor cost of forming, implementing and taking into account the impact of interactive tasks on the success of the educational process participants. The purpose of the study is to substantiate the introduction of relevant information technologies into the educational process, as well as approaches to the verification and formation of knowledge. It tested the main hypothesis: tasks aimed at interactive activity better help students in mastering the material, based on their own perception, than static tasks based on traditional approaches in the educational process with information technologies application. An intraindividual scheme of the experiment is used on the basis of traditional and interactive tasks, different types of tasks are presented to the same group of students. The sample for the participants of the experiment is recruited among the most capable students of the Information Technologies Faculty, bachelors, 2-4 year of experience according to the criterion of academic performance in the framework of specialized disciplines (28 people participated). The variables are empirically selected characteristics that reflect the useful qualities of the task in the context of the educational process. Methods of descriptive statistics are used to test hypotheses. It is noted that the results of the study make it possible to determine and formulate conditions that allow maximum use of the advantages of each of the studied types of tasks. The research confirms the demand for the development of teaching tools for students using interactive tasks, indicating the boundary conditions under which, according to the author, an interactive approach to the construction and implementation of tasks can demonstrate its effectiveness.
Adaptive Aspects of the Social Situation of the Development of Adolescents in the Conditions of Teaching in the Organization of Secondary Vocational Education

Published: July 2021

The study aims at theoretical analysis and empirical identification of adaptive aspects of the social situation of adolescents' development to the new learning conditions. The article presents the materials of the first stage of the empirical study obtained on a sample of 1st-year students of the Moscow organization of secondary vocational education. The study involved 500 respondents aged 16 to 17 years, of which 92% were female. The study included measurements on 7 scales for 5-7 days. We used a projective closed method for assessing the formation of the components of educational activity (it includes two options: for boys and girls). The obtained data suggest that the natural process of adaptation of adolescents to the new conditions of college education is based on its complementary components. At the same time, entering a new situation of social development is accompanied by the emergence of a number of contradictions between the actual needs of a young person and the conditions for their satisfaction. The need to form a system of interpersonal relationships with both peers and significant adults (teachers) actualizes the need for self-affirmation, which is characteristic of the younger adolescence, the previous stage of personal development. The revealed contradiction leads to the formation of an uncertain professional picture of the world.
