ABSTRACT COVID-19 began in December 2019 in Wuhan City, China, and on March 11, 2020 it was classified by the World Health Organization as a pandemic. It is an asymptomatic infection that can progress to severe respiratory conditions. In adults, it is more prevalent, but is also observed in children, with the occurrence of extra respiratory symptoms, such as oral and cutaneous manifestations. This literature review aims to report the oral and cutaneous manifestations of COVID-19 in pediatric patients. The bibliographic search strategy was carried out in the PubMed, SciELO and Bireme databases on August 1, 2020, using MeSH Terms “COVID-19”; “Child”; “Oral Manifestations”; “Skin Manifestations”; “Ageusia”; “Dysgeusia” and corresponding Decs, and also manual search, without language restriction. The stages of search, screening, selection, evaluation of studies and data extraction were performed by four independent reviewers. Nine studies that met the eligibility criteria were identified. The most cited oral and cutaneous manifestations were, respectively, taste dysfunction in adolescents and erythematous eruption in extremities and trunk. Health professionals should be aware of these manifestations, however, this is a recent theme in the literature, and more careful studies with greater strength of evidence still need to be performed.

Da contracultura à somaterapia: a criação e o desenvolvimento inicial de uma terapia anarquista
Authors: Ferraz Giovan Sehn
Published: March 2021

Resumo Este trabalho faz parte de uma pesquisa maior, na qual se procura compreender como a somaterapia de Roberto Freire surgiu e se desenvolveu a partir da contracultura dos anos 1970. Abordam-se a criação e o desenvolvimento inicial da somaterapia, partindo do que se compreende ser um “mito de criação”: uma narrativa ordenada e coerente que explica o surgimento da terapia e que aparece, de forma recorrente, com poucas alterações. Analisam-se, ainda, narrativas posteriores a esse período que remetem ao processo de nomeação da somaterapia. Nesta análise, são encontrados conflitos de dados e incongruências que indicam a complexidade desses processos e o esforço dos autores no sentido de ordenação e legitimação da técnica terapêutica.

Abstract Dermatobia hominis is a parasite widely distributed in neotropical regions. The parasitic phase of the cycle is characterized by the formation of a subcutaneous nodule in the host, which can promote infestation by other dipterans and skin infections. The aim of this report is to register parasitism by D. hominis in free-ranging Panthera onca captured in the Brazilian wetland and to determine significant biological and meteorological factors that are likely to influence the presence of larval parasitism in captured wild jaguars. Between 2011 to 2020, 34 jaguars were captured and examined manually by searching for lesions characteristic of myiasis. By manual compression in the subcutaneous nodules, larvae morphologically identified as D. hominis (first and third instars) were collected from 13 jaguars. A multinomial logistic regression showed that adult jaguars had 16.49-fold higher odds of being parasitized than subadults. Thus, jaguars captured in the season of July–September have 34.01- and 11.42-fold higher odds of being parasitized compared to the seasons of October–December and April–June, respectively, which is associated with high total monthly precipitation in the previous season. The present study is the first to describe parasitism by D. hominis larvae in jaguars.
A new circular economy framework for construction projects
Authors: Medina Eurica Mae , Fu Feng
Published: March 2021

Circular economy (CE) is a holistic, viable solution to the ‘take-make-dispose of’ system of the linear model that enhances economic growth without threatening environmental and social value. Its principles are based on product optimisation, waste elimination and regeneration of natural systems. In this paper, a pilot study evaluates the feasibility of implementing CE in construction projects, followed by the development of a new framework with strategies for altering current construction activities for greater circularity. To demonstrate the benefits of implementing a CE model, a critical assessment of its impacts in the industry was made that considers costing, environmental impacts and legislative action. A new comprehensive CE framework was developed that details a set of indicators, action plans and resources allocated to assess the performance of the strategy implementation, specifically designed for building cycles. To address the challenge of monitoring progress on the transition towards circularity, quantitative tools using a life-cycle approach were developed in this study including an embodied carbon dioxide emission calculator and databases for waste and circularity indexing of common construction materials. The framework, accompanied by these tools, was applied to a construction case study to verify its feasibility in combining scientific and policymaking guidelines. Good practice recommendations were also offered, based on the qualitative research undertaken, to enrich the study further.
Using shell-type tuyeres at Pierce–Smith horizontal converters of the Nadezhda Metallurgical Plant

Published: March 2021

Since 2015 the processing capacity reconfiguration at the Polar Branch of MMC Norilsk Nickel (hereinafter PB) sets new goals for conventional pyrometallurgical processes of smelting and converting. The design flowsheet of Kolesnikov Nadezhda Metallurgical Abstract: Plant (hereinafter NMP) provided for «cross-converting» when copper matte was first processed in one converter to produce blister copper followed by nickel matte processing to yield copper-nickel converter matte bypassing the discharge of dry coagulated slag. This flowsheet allowed for converter heat balance optimization, decreasing the formation of refractory reverts and significant extension of the converter campaign. PB Nickel Plant shutdown resulted in copper processing elimination at NMP and switching the converters to the conventional nickel converting flowsheet. In turn, it gave rise to the need for solutions to extend converter campaign while maintaining the possibility to process large amounts of nickel slag from the second converting stage at the PB Copper Plant. For this purpose the series of lab experiments were carried out to develop the technology and design documentation for the system to supply oxygen-enriched air (up to 45 %) to horizontal converters using shell-type tuyeres. In addition, literature data were analyzed on this topic along with the experience of smelters in this area. Process design calculations were done. The efforts were taken in cooperation with the PB engineering personnel and Laboratory of Pyrometallurgy of LLC «Gipronickel Institute». The use of reduced diameter shell-type tuyeres to inject the oxygen-air mixture was found to decrease the converter blowing and off-gas volumes. The decline in off-gas quantity leads to reduced heat load on the converter mouth and flue duct system, as well as to lowered converter dust entrainment. The use of oxygen-enriched blowing implies the higher smelt heating rate. Excess heat compensation requires timely charging of cold reverts and flux. In emergencies (if cold reverts are not available) the oxygen content of the blowing has to be reduced until switching over to air blowing. The series of the above efforts will offer a possibility to use the shell-type tuyeres keeping the converter off-gas temperature at the current level. Thus continuous monitoring and efficient control will ensure the off-gas temperature and volume at the inlets of gas cooling and cleaning systems not exceeding the limiting values. The introduction of the reduced diameter shell-type tuyeres for air-oxygen mixture injection does not require any upgrade of the existing gas cooling and cleaning systems. Moreover, switching to these tuyeres will reduce gas load on the flue duct system and heat load on the water-cooled dust cap, lower dust entrainment and non-recoverable dust losses after the gas cleaning system.

It is proposed to use a spent cracking catalyst of petroleum hydrocarbons containing 1 wt.% of rare earth element (REE) oxides as an alternative REE feed source. The study covers the process of removing silicon in the form of ammonium hexafluorosilicate (NH4)2SiF6 by sintering an oil cracking catalyst sample with NH4F and subsequent (NH4)2SiF6 sublimation to produce an aluminum-containing concentrate of rare earth elements. The orthogonal central compositional planning of the experiment was used to study the effect of three factors: sublimation temperature (350 to 400 °С), duration (40 to 80 min), and weight of the catalyst fluorinated sintered mass (5 to 10 g) on the (NH4)2SiF6 sublimation completeness. Results obtained in the experiment were used to build a second-order model, which correlate with experimental data. The dynamics of (NH4)2SiF6 sublimation removal was determined for sublimation durations of τ = 10, 20, 40 and 80 min at processing temperatures of 350, 375 and 400 °C. The (NH4)2SiF6 removal degree values calculated based on the second-order model for τ = 44, 48, 52, 56, 60, 64, 68, 72, and 76 min fit well the experimental curves. Spectra of fluorinated catalyst samples before and after sublimation were studied using X-ray phase analysis and IR spectroscopy. The data of IR spectroscopy and X-ray phase analysis are in good agreement and show that (NH4)2SiF6, (NH4)3AlF6 and unreacted NH4F are present in the catalyst with NH4F sintered mass, and only aluminum compounds are detected – NH4AlF4 and AlF3 after sublimation. These data indicate the completeness of the sublimation removal of silicon from the catalyst and NH4F sintered mass with NH4AlF4 and AlF3 aluminum compounds only observed after sublimation. REE concentration is 15 % due to silicon removal.

Published: March 2021

The paper focuses on the study of the gold-bearing ore dressability. According to technological research, the average gold content is 11.88 g/t. The silver content is insignificant – 2.43 g/t. Main ore minerals in the sample are pyrite and pyrrhotite. According to mineralogical and X-ray structural analysis, the average content of these minerals in the ore is about 6 % (in total). Main rock-forming minerals of the original ore are: quartz (60.1 %), quartz-chlorite-mica aggregates (3.8 %), carbonates (7.1 %). According to the study results, it was found that the gold recovery in the GRG test was 72.75 % with a total concentrate yield of 1.34 % and a content of 664.78 g/t. At the same time, the gold content in tailings was 3.29 g/t. A stage test showed that it is advisable to use a two-stage scheme for ore processing by gravity technology only. The first stage is in the grinding cycle with the 60–70 % ore size, and the second stage is with the final classifier overflow size of 90 % –0.071 mm. Centrifugal separation has high performance as a free gold recovery operation in the grinding cycle. A concentrate with a gold content of 2426 g/t was obtained with a yield of 0.31 % and a recovery of 63.74 %. The beneficiation of first stage tailings ground to 90 % –0.071 mm at the KC-CVD concentrator (modeling) made it possible to extract gold into a total gravity concentrate (KC-MD + KC-CVD) of 87.25 % with a concentrate yield of 22.63 %. The gold content in tailings was 1.97 g/t. The results of gravity and flotation concentration of the original ore indicate the feasibility of using a combined gravity-flotation technological scheme. In a closed experiment of the initial ore beneficiation according to the gravity-flotation scheme at a natural pH of the pulp (without adding acid), the following products were obtained: gravity concentrate with a gold content of 2426 g/t at a yield of 0.31 % and recovery of 64.06 %; flotation concentrate (after the II cleaning) with a gold content of 122 g/t at a yield of 2.90 % and recovery of 33.01 %; the total gold recovery in the gravity-flotation concentrate was 94.07 % with a yield of 3.21 % and an Au content of 345.87 g/t, the gold content in the flotation tailings was 0.72 g/t.

Published: March 2021

The article presents the results of research determining the most effective technologies for increasing metal yield in the processing of aluminum-containing waste. In particular, peculiarities of the processes of melting aluminum alloys were analyzed using complex methods of furnace and off-furnace processing of charge material containing an increased amount of shovelling scrap and swarf. Studies on the impact of charge preparation and aluminum remelting technology were carried out in SAT-0,16 and IAT-0,4 furnaces on the АК12М2 alloy. Experiments proved that batchwise loading 20 kg of swarf briquette preheated to 300–400 °C into the SAT-0,16 furnace with the addition of flux (composition: NaCl – 50 %; KCl –35 %, Na3AlF6 – 15 %) in the amount of 3 % of total metal mass is the most efficient technology. This technology makes it possible to achieve a metal yield of about 94 %. The study of the remelting technology influence on IAT-0,4 furnace metal yield showed that the greatest effect can be obtained in case of furnace charge (95 kg swarf briquette) by batches of 2 kg into the 7 kg liquid bath with modifier flux (composition: NaCl – 62 %; KCl – 13 %, NaF – 25 %) added in the amount of 2 % from the total metal mass. This technology provides up to 93.5 % of metal yield. Data from 10 series of 5–9 melts were also analyzed with the comparison of metal yield results depending on the mass of briquetted swarf charged into the furnace. A histogram of the change in the porosity of AK12M2 and AK9 samples depending on the content of swarf in the charge (from 0 to 45 %) during remelting. It was found that an increase in the content of swarf in the charge, all other things being equal, leads to an increase in the average porosity score, which indicates the need for additional refining of such melts.

Published: March 2021

The microstructures of alloys formed during the sintering of tungsten powder mixtures (PV2, 3.8–6.0 μm average particle size) and copper (PMS-11, 45–60 μm fraction) prepared by various methods were compared. The methods included simple metal powder mixing, mechanical activation (MA) of metal powders, copper precipitation from the solution of its sulfate (CuSO4·5H2O) on tungsten powder with simultaneous mechanical activation. The molar ratio of metals in mixtures Cu/W = 1. An aqueous solution for copper deposition included diethylene glycol (up to 30 %), glycerin (up to 8 %), hydrofluoric acid (up to 0.1 %), wetting agent OP-10 (up to 0.8 %). Mechanical activation was carried out in an AGO-2 planetary mill with 200 g of steel balls charged into the drums rotating at 2220 rpm for 5 min. Reduced copper in the solution and in the air rapidly oxidizes to the Cu2O oxide, so the composite powders obtained were washed, dried, and stored in an argon atmosphere. Samples pressed from the powders obtained (tablets 3 mm in diameter, 1.5–2.0 mm in height with a density of 7.7–8.0 g/cm3) were sintered in argon at atmospheric pressure and temperatures from 1000 to 1500 °C. During the sintering of Cu–W composite particles, several areas of the process can be distinguished. «Solid phase» sintering occurs at the contact points of composite particles at temperatures lower than the copper melting point. When samples are heated from the melting point to 1200 °C, samples are sintered by the liquid-phase mechanism from the conventional mixture of metal powders to form a low-porous cake. When composite powders obtained by MA during the copper deposition and MA of metal powder mixtures are sintered, samples are delaminated with the formation of large pores elongated perpendicular to the pressing axis and partially filled with copper melt. When samples obtained by powder MA are heated above 1400 °C, phase separation occurs and almost all copper is displaced from the sample to the surface.

Current State of Russo-Chinese Investment Cooperation
Authors: Sukhodolov Yakov
Published: March 2021

China is traditionally a leading foreign trade partner of Russia. And its share in the total volume of foreign trade has a positive dynamics. At the same time, the dynamics of the Russo-Chinese investment cooperation sufficiently lags behind the dynamics of development of the Russo-Chinese foreign trade relations. At present, China considerably lags behind France, Germany, Great Britain and Italy in regard to direct investments in Russia’ economy. The major part of direct investments from China falls upon the mining and petrochemical industries, the wood and paper complex, the agriculture, and the real estate sphere. At the same time, the Chinese investors also implement several investment projects in the machine-building sphere. The Russo-Chinese cooperation has good prospects, especially in the sphere of implementing joint transport-logistic and infrastructural projects, as well as the projects in processing industry.
Translation: Mapping and Reconfiguration of the Language World
Authors: Gu Junlin , Pimenova Marina
Published: March 2021

The article discusses using the tenets of the linguistic world picture theory in terms of translation by analyzing the methods of interpreting the inscription on a public sign in a Chinese forest park. When the original and translated fragments of the language pictures of the world are the same or similar, the word-based translation is justified from the standpoint of conveying the pragmatic, semantic and grammatical value of the text. When the language pictures of the world are different and do not correspond to each other, the word combinations phrases of the source language cannot be literally translated into the target language. The word-based translation in such cases is a dead translation that will cause translational errors. Using the semantics of the source language, the translator must reconstruct the picture of the world in the target language in order to convey the pragmatic value of the original. The difference between languages is the manner they reflect the picture of the world. Various languages fix various worldviews. The characteristics of each particular language are limited by the linguistic consciousness of people who use the language. This individual worldview is also a unique view of the world. The theory of the language picture of the world contains a linguistic study of the relationship between the language, the thinking and the reality from a cognitive point of view. It begins with linguistic facts and refers to the cultural characteristics of peoples and differences in their thinking, expressed in the linguistic facts. Its essence lies in the cognitive reproduction of the objective world in the human mind, which is the subject of knowledge based on his own perceptual experience and the language of his national culture. The theory of the language picture of the world lies in the fact that it interprets the cultural heritage of the certain people from the point of view of the language. The characteristics of each particular language are limited by the language consciousness of people. Different languages are, in fact, different worldviews, which is an expression of the unique language pictures of the world.

Published: March 2021

Despite the increase in the level of knowledge intensity of the leading world powers, the expansion of the segment of «complex» services, innovative and high-tech products in their industry structure, the importance of hydrocarbons in the development of absolutely all national economies in the XXI century does not weaken. A fierce competition continues for control of the oil and gas markets, in which Russia, as a country whose economy depends on the volume and prices of exported energy resources, should rely on strengthening cooperation with China. This will allow it not only to maintain the return on its existing comparative advantages, but also to attract foreign capital for infrastructure development.
The Leave of Court Requirement for Instituting Derivative Actions in the UK: A Ten-Year Jurisprudential Excursion
Authors: Hamadziripi Friedrich , Osode Patrick C
Published: March 2021

The judiciary-exclusive role to allow or deny the commencement or continuation of contemporary derivative litigation is one of the critical aspects of such proceedings. Before the 2006 codification, derivative actions were brought under the common law as exceptions to the rule in Foss v Harbottle (1843) 67 ER 189. However, after realising intolerable deficiencies in the common law, the United Kingdom Law Commission (the Law Commission) recommended that there should be a new derivative procedure that met modern demands. This resulted in a statutory derivative remedy which can be activated in terms of Chapter 1 of Part 11 of the UK Companies Act, 2006. The effectiveness of legislative regulatory devices generally, and commercial law-related ones in particular, may to a greater extent depend on judicial interpretation and application. A conservative and literal interpretive approach that is purpose-neutral will significantly undermine the prospect of the current derivative remedy regime’s achieving the intended policy objectives. To that end, this contribution examines several court decisions handed down after the enactment of the 2006 Act and spanning over a period of approximately ten years. Ultimately, it will be considered whether the leave requirement in English derivative litigation is proving to be an invaluable and indispensable procedural prerequisite or an implausible barrier to honest litigants.
Social Protection Instruments and Women Workers in the Informal Economy: A Southern African Perspective
Authors: Fourie Elmarie
Published: March 2021

The world of work has changed and in some instances a realisation now exists that certain forms of work are a reality and not a passing occurrence, and it is of the utmost importance that international regulation provides for this, including work in the informal economy. Specific vulnerable groups and challenges have been identified by international regulators and must now be addressed to extend protection to these workers. International regulation must promote freedom through the enhancement of the capabilities of these workers. International instruments can function as key strategic tools to address inequalities in the workplace by increasing the capabilities of vulnerable groups such as women through empowerment initiatives. The purpose of this contribution is to identify and critically consider the relevant international social security instruments of the ILO and the UN, the impact of international standards, and other global initiatives directed at the social protection of women workers in the informal economy.

Os princípios macro hermenêuticos do santuário celestial e suas implicações – Parte II
Authors: Teixeira Carlos Flavio
Published: March 2021

Este artigo é o segundo de um estudo de duas partes que trata dos princípios macro hermenêuticos do santuário celestial conforme reivindicados nas Escrituras Sagradas e identificáveis à luz da compreensão historicista do tema. A primeira parte definiu a macro hermenêutica e relembrou sua importante conexão com as realidades do santuário celestial. Também reconheceu a existência e significado dos princípios fundamentais de correspondências ontológica, estrutural e funcional entre os santuários celestial e terrestre – conforme estabelecidos na Bíblia e reafirmados nos escritos de Ellen G. White – enfatizando o papel macro hermenêutico desses princípios para a constituição e manutenção do sistema teológico adventista do sétimo dia. Nesta segunda parte, à luz dessa perspectiva por vezes chamada de literal, se destaca a emblemática coexistência das noções metafórica e simbólica acerca do santuário celestial que vêm ganhando espaço no meio adventista, notando-se as implicações e desafios de tais proposições para a teologia e a prática da Igreja Adventista.
The Theological Necessity of the Investigative Judgment: Albion Ballenger and His Failed Quest to Subvert the Doctrine—Part II
Authors: Jankiewicz Darius W.
Published: March 2021

A lo largo de la historia de los adventistas del séptimo día, el juicio investigador (o juicio pre advenimiento) ha sido una de las doctrinas más controvertidas, desafiada y cuestionada más que cualquier otra creencia adventista. Este trabajo explora las razones por las que los críticos del adventismo, y en particular Albion Fox Ballenger, objetan la doctrina del juicio investigador. Ballenger fue un ministro adventista que se convirtió en uno de los críticos más fuertes de la doctrina adventista del santuario durante la primera parte del siglo XX. Todas las demás críticas a la doctrina, y en particular al juicio investigador, se remontan a Ballenger. Este artículo es la segunda parte de una serie de dos sobre el juicio investigador. La primera parte ofreció una exposición abreviada de la soteriología de Ballenger y su crítica de la doctrina del juicio investigador. Esta segunda parte concluye con un análisis teológico de la crítica de la doctrina propuesta por Ballenger y sus seguidores evangélicos en el contexto de una comprensión más amplia de la soteriología protestante.

Published: March 2021

La pandemia de la COVID-19 ha cambiado de forma radical e impredecible el entorno competitivo de las empresas, siendo España uno de los países de su entorno que se ha visto más afectado. En este nuevo contexto, para hacer frente a unas condiciones del entorno extremadamente dinámicas, complejas y difícilmente predecibles, las empresas para poder adaptarse necesitan estar en posesión o desarrollar una serie de capacidades específicas. Este artículo pretende mostrar que el desarrollo de las TIC, la flexibilidad laboral y la capacidad de innovar son tres factores que favorecen la capacidad de las organizaciones para adaptarse a los nuevos y cambiantes entornos competitivos provocados por la emergencia sanitaria de la COVID-19. La capacidad de adaptarse se refleja a través de su habilidad para dar continuidad tanto a la gestión y monitorización de sus operaciones como a la relación con sus clientes a lo largo de todos los niveles del proceso de venta. Para analizar esta relación, se entrevistó a directivos de empresas durante los meses posteriores a la declaración del estado de alarma en España. Mediante la aplicación de la técnica de análisis multivariante PLS-SEM, se ha estimado que un mayor nivel de los tres aspectos indicados se relaciona positivamente con una mejor adaptación de las empresas tanto a las nuevas necesidades como a las limitaciones de operación en sus respectivos mercados.

El sector laboral se ha enfrentado responsablemente ante las afectaciones del coronavirus (COVID-19) y las adversidades que esta pandemia ocasiona, no obstante, este grupo humano no está excepto de riesgos y de afectaciones psicológicas por la gravedad de la situación en el ámbito laboral, que puede reasentar en la familia. Su actuación es consecuente con la realidad, aunque necesita de condiciones emocionales diferentes que le permitan continuar en su desempeño. La investigación tuvo como objetivos: diseñar un instrumento para medir el salario emocional y validar el instrumento creado para la inserción del salario emocional ante la COVID-19. La metodología empleada fue de tipo no experimental, descriptivo y transversal, y como variable de interés de estudio: el salario emocional. Se diseñó y validó un instrumento para medir el salario emocional, con un alfa de Cronbach de 0,925, el cual fue aplicado a una muestra de 207 trabajadores. Los encuestados manifestaron una predisposición favorable al instrumento y su percepción de salario emocional es considerada como alta. Como conclusiones se obtiene la reafirmación de la inserción del salario emocional, con estrategias de atención al recurso humano de forma personalizada, con respecto a sus emociones del ámbito laboral ante la escalada de la COVID-19

La súbita irrupción de la pandemia COVID-19 ha propiciado profundos cambios sociales y económicos. Las empresas se han visto obligadas a pivotar sus modelos de negocio para asegurar su continuidad. El presente estudio profundiza en las tendencias observadas en los cambios de los modelos de negocio durante esta crisis. El objetivo de esta investigación ha sido identificar los factores que se encuentran detrás de las iniciativas que han adoptado las empresas, pues presumiblemente se consolidarán y serán la base de disrupciones que eran impensables antes de la pandemia. Una rápida revisión sistemática ha permitido recuperar y resumir los resultados de las investigaciones más relevantes en este campo. Se han seleccionado veintiocho artículos de las principales bases de datos científicas, Scopus y Web of Science, utilizando el diagrama de flujo de decisiones de inclusión propuesto por PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Los principales hallazgos del análisis cualitativo que se ha realizado destacan la importancia de la tecnología, con la generalización de canales digitales de marketing y ventas en las empresas, el teletrabajo y el consumo de productos tecnológicos como la Inteligencia Artificial; la adopción de innovaciones relacionadas con la propuesta de valor, en la mayoría de las ocasiones en forma de nuevos productos y servicios, como forma más común de experimentación de cara al consumidor; y la generalización de iniciativas de colaboración entre todos los actores del ecosistema empresarial.

Published: March 2021

Para ser sostenible en el tiempo, la responsabilidad social empresarial debe incidir en su entorno y sus colaboradores en tiempos de incertidumbre. Una crisis en los sistemas de salud, políticos y económicos en Perú se ha desencadenado como resultado de la COVID-19. El propósito de esta investigación fue determinar la relación entre la responsabilidad social y la gestión de calidad en una empresa peruana de seguros. La metodología utilizada para lograr el objetivo fue de enfoque cuantitativo, diseño no experimental y de alcance transversal. Se encuestaron a 331 colaboradores en la ciudad de Lima. Se aplicó como instrumento un cuestionario validado por juicio de expertos y con una confiabilidad de Cronbach >0,96. Los resultados evidencian que la empresa apoya a las comunidades menos privilegiadas en campañas de salud y nutrición a través de colaboradores voluntarios de los programas de responsabilidad social empresarial que contribuyen al cuidado del medio ambiente. En conclusión, existe una relación significativa entre las variables estudiadas; sin embargo, la alta dirección de la empresa aseguradora es consciente de que aún falta trabajar en la gestión del conocimiento y estrategias para conseguir la participación de sus colaboradores y proveedores en las labores de responsabilidad social en tiempos de pandemia, que permitan mayores niveles de competencia.

Technology and internet usage, which has become a common practice in almost every context, sometimes becomes a source of stress for the individuals, on the other hand, it also acts as a means of coping with stress. The adaptation process to be experienced by individuals who have participated in a new culture may form stress sources in these individuals, and this stress may lead to internet addiction. The purpose of this research is to review the stress sources of the teachers assigned in Van province of Turkey from other provinces and the relationship between the stress sources and internet addiction tendency. The research was conducted with 17 teachers working in Van province. The data of the research was collected by semi-structural interview form developed by researchers. Descriptive analysis and content analysis techniques were used in the analysis of data. As a result of the research, it was found that teachers demonstrate tendency of internet addiction through developing stress due to cultural differences, however they do not attempt to prevent it. It is suggested to detect internet addiction tendencies in teachers assigned in different cultures by research, to prevent the development of addiction behaviour by early interventions and to include teachers assigned in new cultures in cultural adaptation trainings.
