Every organisation has invested its time, effort and resources to recruit, train and pay employees’ salaries. These investments are important to ensure that the organisation can produce high-quality employees who will remain with the organisation for a long period of time and be part of the successful members of the service team. Although a lot has been done to ensure that employees remain with the organisation, research has found that employee retention remains to be a problem to most organisations. In validating whether the findings from past studies are still consistent with the present situation, the present research aims to further investigate whether work environment, leader communication and job satisfaction still present significant relationships with hotel employee retention. In total, 550 self-administered questionnaires were distributed to hotel employees attached to 3-star and 4-star hotels located in Klang Valley, Malaysia. Of the total being distributed, 329 were returned and considered usable for data analysis. The hypothesised relationships between variables were tested using the multiple regression analysis. The findings reveal that workplace environment, leader communication and job satisfaction are significantly related to hotel employee retention. The results also demonstrate that job satisfaction mediates the relationship between workplace environment, leader communication and employee retention. The findings of this research advance the understanding of employee retention and create awareness among hotel management to better appreciate the dimensions of transformation which are essential towards ensuring employee job satisfaction. This will consequently lead to a long-term employee retention. Apart from the findings, the paper also highlights the limitations and suggestions for future research. Keywords: Workplace environment, leader communication, job satisfaction, employee retention, hotel industry.

Organisations need to perform, productivity needs to be improved and organisations’ activities need to be more effective, especially after the world economic crisis due to the Covid-19 pandemic. Therefore, the need for quality improvements is crucial in both manufacturing and service sectors. The main purpose of this paper is to present an analysis of internal communication patterns in TQM implementation in Malaysia's manufacturing organisations. This is a multiple case study done using qualitative in-depth interview technique of data collections with 14 informants representing five large manufacturing organisations. Open-ended questions in semi-structured interviews enabled informants to describe their answers based on themes. The study has been carried out in manufacturing organisations originating from three different continents; two Malaysian local organisations, two eastern and one western organizations, and all of them located in Malaysia. In selecting the informants, the study adopts a judgment type of purposive sampling techniques. Results show that the most preferable and reliable communication medium between superiors and subordinates is still face-to-face meetings, although we are in the era of technology and IR4.0. Meanwhile, telephones are popular among the administration staff. The preferable form of communication between internal-operational is formal, without denying that informal form ofl communication is also important. Keywords: Internal communication, organizational communication, multiple case study, systematic process analysis, TQM.

Published: December 2021

A pesquisa tem como objeto os desafios, a necessidade e a importância da Pedagogia Hospitalar para a cidade de Ponta Grossa-Pr. E apresenta como objetivo analisar e compreender a pedagogia hospitalar como uma nova atuação em nossa cidade, visando o pleno desenvolvimento de crianças e jovens hospitalizados. Com o passar dos anos muito se conquistou no âmbito educacional hospitalar e, muito se adquiriu com as legislações vigentes no país como constam na Constituição Federal de 1988, no Estatuto da Criança e do Adolescente, nas Diretrizes Operacionais para o Atendimento Educacional Especializado na Educação Básica, ressaltando que a pedagogia hospitalar faz parte da modalidade de Educação Especial. Percebeu-se, que, a partir de questionário realizado com uma pedagoga de um colégio particular da cidade de Ponta Grossa-Pr, mesmo com amparo legal, a pedagogia hospitalar na cidade ainda não é reconhecida e há falhas nas políticas públicas para firmar parcerias entre educação e saúde e muito ainda precisa ser discutido para que essa atuação de fato aconteça na cidade. A pesquisa de cunho qualitativo trouxe reflexões acerca da pedagogia hospitalar e a necessidade de uma implantação na cidade, visando a qualidade da educação e fazendo com que a garantia das leis seja efetiva, pois sabe-se que a educação é um direito de todos. Espera-se que a pesquisa realizada também através de bibliografias, seja significativa e contribua para um melhor aprofundamento também de acadêmicos que apoiem e lutem por esse direito profissional e social.

IMPLICAÇÕES DO RACISMO NO PROCESSO EDUCATIVO DE ESTUDANTES NEGROS
Authors: Matos Patrícia Modesto , França Dalila Xavier de
Published: December 2021

O presente estudo é fruto de uma pesquisa mais ampla desenvolvida durante o mestrado e tem como objetivo verificar as implicações do racismo na trajetória escolar dos estudantes negros oriundos de escolas públicas no interior do estado da Bahia e de Sergipe. Tivemos o apoio teórico de estudos desenvolvidos acerca dos efeitos do racismo na trajetória escolar dos discentes. Utilizamos o Software SPSS para analisar as respostas de 120 alunos inseridos nos anos finais do ensino fundamental.  Os dados foram analisados mediante a associação da cor da pele com a experiência de racismo e o desempenho escolar. Evidenciamos que não houve diferença significativa na experiência de racismo, tão pouco no desempenho escolar dos estudantes negros quando comparados com os brancos. Contudo, identificamos que quanto mais o aluno percebe que foi alvo de racismo, maior o atraso em sua escolaridade. Assim, além de investigar as disparidades no desempenho escolar de alunos negros e brancos, sugerimos que pesquisas futuras se debrucem acerca do modo como o racismo opera na produção do fracasso escolar.

Published: December 2021

The game is considered as a professional correctional and preventive resource in working with de-viant behavior of children and adolescents. One of the reasons for the deviant behavior of preschool children is recognized as an insufficient level of social and communicative development. Folk game has features that affect the parameters of social and communicative development of children (the ability to follow the rules, adequately evaluate themselves, and establish friendly relations with peers). The game program, which is attractive for children, proposed in the study, includes a variety of games with strict rules, which, however, provide great opportunities for improvisation and the manifestation of children’s individuality. Psychological diagnostics of the parameters of social and communicative development experimentally showed the effectiveness of the program. The socio-metric status at-risk kids has also increased. Aggressive manifestations in behavior have significant-ly decreased, indicators of the emotional and volitional sphere have improved.

The Essence and Interaction Mechanisms of Subjects of Education in Forming the Personality of Students of the Educational Organization of the Ministry of Internal Affairs of Russia
Authors: Konopleva E.A.
Published: December 2021

The article reveals the issues of educational work with students of educational organizations of the Ministry of Internal Affairs of Russia. The educational process is considered as the implementation of a scientifically grounded and normatively regulated system of measures for the moral and professional-psychological preparation of the personality of the future employee of the Internal Affairs agencies for professional activity. The realities of the current moment impose very high requirements on the personality of an employee of the Internal Affairs agencies, and therefore this personality requires not only detailed study, but also a constant system-built psychological and pedagogical influence. The specifics of law enforcement is determined not only by the tense organizational, intellectual and emotional situation, but also by the need to act at the intersection of ethics and law, moral and legal regulation. At the same time, educational work with students, as a system of purposeful psychological and pedagogical influence on the consciousness, feelings and behavior of a person, should be carried out with the maximum consideration of individual characteristics. The solution of these problem areas, as well as the implementation of the most important task of personal education-interiorization of values, is possible when using an integrated approach in support of educational activities, where the leading role is assigned to the moral and psychological support of educational activities.

Published: December 2021

The article presents a study devoted to the study of cognitive dysfunctions in patients with schizophrenia and endogenous depression in their relationship with the functioning of the magnocellular and parvocellular systems. Mismatch in the work of neural systems leads to violations of the integrity of visual perception and to a violation of the selectivity of thinking in endogenous patients, which makes it difficult to assess and select meaningful, essential information in the formation of judgments. 60 patients with schizophrenia (43 (75%) male and 17 (25%) female; mean age ― 34.0±12.0 years) and 25 patients with endogenous depression (11 (44%) male and 14 (56%) female, mean age ― 38.0±13.6 years) with the use of psychophysiological (the method of visocontrastometry with an assessment of the contrast sensitivity of the visual system, the method of assessing the noise immunity of the visual system) and experimental psychological methods (Trial-Making test by Reitan, Memorizing 10 words, Poppelreiter's figures, Incomplete images, Excluding the 4th superfluous). The established features of cognitive dysfunctions in endogenous depression and schizophrenia are associated with the features of the functional state of the magnocellular and parvocellular neuronal systems and the nature of the interaction of these systems. The specificity of impairments in cognitive functions in patients with endogenous depression is due to changes in the dynamic component of cognitive activity, while the specificity of impairments in cognitive functions in patients with schizophrenia is associated with changes in the selectivity of information and early sensory defects. The data obtained make it possible to develop an idea of the profiles of sensory-cognitive impairments in endogenous depression and schizophrenia, which is of particular importance for differential diagnosis.

The objective of the present study is to investigate the relationship between the receptive language, and the index of non-verbal intelligence and the level of severity of autistic disorders in primary-school-aged children with Autism spectrum disorder. One of the main areas influenced by autistic disorders is communication. Therefore, the study of the language abilities of such children and factors that affect them provides a better approach to the therapy and education. The sample included 50 children aged 7–11 years diagnosed with autism spectrum disorders. Children were tested using the KORABLIK method (basic linguistic skills), the Kaufman Assessment Battery for Children (KABC-II) or the Wechsler Intelligence Scale for Children ― Third Edition (WISC-III) (non-verbal intelligence), the Autism Diagnosis Observation Schedule ― Second Edition (ADOS-II) (autistic traits). The results support the hypothesis of the relationship between receptive language skills, the index of non-verbal intelligence, and symptoms of autism. The severity of autistic traits is negatively associated with some phonological and lexical levels of the receptive speech, as well as with understanding of discourse. The non-verbal intelligence index is positively associated with speech comprehension at all levels. A specific feature of receptive language in children with Autism spectrum disorder aged 7–11 years is the uneven development, which is associated with the severity of autistic traits and is not associated with the intelligence level.

Authors: Volkova T.B. , Osokina A.D.
Published: December 2021

This article discusses the application of Johnson’s algorithm to analyze the work of a volunteer help desk and the work of an online store if the initial data for the algorithm are random numbers from a given interval. For this purpose, a program has been developed for solving the Johnson problem for modeling work, i.e. simulating the processing of applications (orders, calls), written in the Python programming language using IDE – PyCharm 2021.1, Qt Designer and PyQt5, in which the processing time of applications is a random variable from a given interval. The analysis of the results obtained allows us to make recommendations on the number of applications that the service system can process if the processing time is random, but belongs to a given interval, as well as predict the waiting time for applications to arrive.
Modern Realities of Software Project Management

Published: December 2021

The need to maintain the workflow in conditions of forced disconnection has increased the need for software products. But it turned out that the quality of many of them is lower than expected. One of the reasons is that users with different quality criteria began to work with them. Another reason is that the products have objectively become unacceptably low quality, largely due to errors in the management of the project. The scale and significance of a modern software project require its implementation according to one of the classical models: it will ensure quality. However, due to the desire to get ahead of competitors, flexible methodologies are used, reducing deadlines and losing quality. And the larger the project, the higher the risk of quality loss and the higher the cost of losses. How to combine the benefits of both approaches without getting their disadvantages?

Authors: KÜTÜK Nurşah , CETINKAYA GÜRER Sevil
Published: December 2021

Graphene is an important material that has attracted attention in recent years due to its large surface area, mechanical strength, thermal, electrical and magnetic properties. In this work, reduced graphene oxide (RGO) was obtained by reducing the graphene oxide (GO) with green synthesis. For this purpose, white cabbage aqueous extract was selected to reduce GO. The total phenolic acids, which are the reducing agent in the extract, were determined according to the Folin-Cioceltau method. It was determined that there is 0.064 grams of polyphenols in 1 mL of white cabbage extract. In order to determine the reduction experimental conditions, a reduction temperature of 25, 50 and 100 ⁰C and 1, 2, 4 and 6 hours of reduction time were studied. Structural characterization of synthesized RGOs was performed with XRD, FTIR and SEM techniques. The results showed that GO was reduced at a reduction reaction temperature of 100 °C and a reduction reaction time of 6 hours. The peak seen at 22.08⁰ in the XRD data is evidence of reduction of GO.

Hesitant Fuzzy Linguistic Decision Making Approach for Stroller Selection
Authors: ECER Billur
Published: December 2021

Having a baby brings new changes and challenges in parents’ life. There is a list of things which are required in order to provide a comfortable life for the baby. Since most of the people have limited economic resources, determination of the things to be bought becomes an important decision for parents. Moreover, the number of alternatives for the items in shopping list (bed, clothes, feeding equipment, stroller, etc.) is very much. Therefore, making a choice among alternative items is necessary. For each item, different alternatives have several advantages over another in views of different aspects. Consideration of several aspects of items would lead to good decisions, and parents must evaluate things in this way. It is aimed in this research to develop an analytic decision-making approach for stroller selection decision of parents. Hesitant fuzzy linguistic terms set (HFLTS) approach was presented in order to model the uncertain situations that the decision makers feel hesitant over various values of a linguistic variable. By using this pattern, elicitation of linguistic information is improved and thoughts of decision makers are represented better in decision models. Under the consideration of hesitant feelings of parents, HFLTS based group decision making approach is utilized to determine the optimum stroller. Apracticeof the presented model is presented to indicate its applicability and the presented decision approach seems useful for stroller selection.

Depression is one of the most common mental illnesses. Impaired neurogenesis is observed in depression. Studying the concentration of biochemical indicators in the blood that may be involved in the pathogenesis of depression, looking for associations with the severity of depressive symptoms can be useful as an objective diagnosis of the disease and predicting the severity of the pathology. We determined plasma concentrations of the monoamine neurotransmitters serotonin and dopamine, and neurotrophic factors involved in neurogenesis (BDNF, CDNF and neuropeptide Y) in depressed patients and healthy volunteers with the same socio-demographic parameters using enzyme immunoassay and mass spectrometry. All study participants were administered the Hamilton Depression Scale (HAMD), the Generalized Anxiety Disorder Questionnaire (GAD-7), and the Center for Epidemiological Studies (CES-D). The cumulative scores on the three scales examined were significantly higher in depressed patients than in controls. The concentration of serotonin, dopamine, BDNF, CDNF, and neuropeptide Y in plasma did not differ between the subject groups and was not associated with the scores on the scales. Positive correlations were found between the content of neuropeptide Y and serotonin, BDNF and CDNF in blood plasma. Thus, although these markers are related to the pathophysiology of depression, they do not correlate with the severity of symptomatology and possibly in plasma cannot reflect processes occurring in the brain.
La crisis cultural arquitectónica en el entorno digital: una cuestión pendiente
Authors: Villanueva Cajide Beatriz , Casas Cobo Francisco Javier
Published: December 2021

Desde su aplicación generalizada al diseño arquitectónico en los primeros años 90s, las herramientas digitales le han aportado innegables beneficios, entre los que destacan los derivados de su excelente capacidad gestora de información y su competencia para producir nuevos desarrollos geométricos. Sin embargo, paralelamente a estos avances, han acentuado la crisis cultural que la disciplina viene sufriendo desde la segunda mitad del pasado siglo. La incorporación del conocimiento arquitectónico acumulado en períodos anteriores resulta especialmente difícil en el caso de los diseños arquitectónicos auto-generados, de base algorítmica. El presente artículo propone la utilización del manifiesto, entendido como texto propositivo de clara estructura y corta longitud, como vehículo cultural apropiado para su utilización en proyectos arquitectónicos basados en el cálculo. Para conseguirlo, es necesario comprender y acotar el género, diseccionándolo después, de manera que sus partes elementales enriquezcan la variedad paramétrica que nutre las conexiones algorítmicas del diseño arquitectónico digital.

La hipertensión arterial es el principal factor de riesgo cardiovascular, y su prevalencia en Paraguay es la mayor de América Latina. El objetivo del presente trabajo fue comparar productos de losartán de 100 mg comprimidos de producción nacional e importada a través de los perfiles de disolución versus su precio. Se tomaron 8 marcas de losartán potásico comercializadas durante el 2017, realizándose los controles de calidad de acuerdo a lo establecido en la Farmacopea Americana (USP 38). Se determinó el porcentaje de principio activo liberado en el medio de disolución establecido por la USP 38, por medio de los perfiles de disolución. Las determinaciones se realizaron por HPLC y espectrofotometría UV/V. Los controles realizados cumplieron con las especificaciones establecidas por la USP 38. No se encontraron diferencias significativas en el análisis estadístico de los perfiles de disolución de las diferentes marcas analizadas. Los resultados demostraron que los precios de las marcas analizadas no afectaban la calidad de los productos, pero sí en el costo del tratamiento de la población de escasos recursos, debido al mayor costo de los productos importados con respecto a los de producción nacional.

Candida albicans es la levadura más aislada de la cavidad oral de personas con VIH. Sin embargo, el uso de antifúngicos ha incrementado el aislamiento de especies no C. albicans resistentes o con sensibilidad reducida. El objetivo del estudio fue determinar las especies de Candida y la sensibilidad a los antifúngicos de aislamientos de la cavidad bucal de pacientes con VIH, que acudieron al Instituto de Medicina Tropical entre julio a diciembre de 2019. Las levaduras se sembraron en Agar Cromogénico Candida (CONDA®, España) para la identificación presuntiva. Las colonias verdes se identificaron por PCR dúplex y las de coloración distinta o PCR negativa mediante el sistema comercial VITEK®2. La susceptibilidad antifúngica de C. albicans se determinó por VITEK®2, y las no albicans por el método de difusión de discos. De 278 levaduras, C. albicans se aisló en 70,9 %, seguido de C. tropicalis (8,3 %) y C. krusei (5 %). C. albicans presentó 93 % de sensibilidad y 2 % de sensibilidad dosis dependiente al fluconazol; 87 % sensibles y 3 % con sensibilidad intermedia frente a voriconazol; 97, 98 y 100 % sensibilidad a flucitosina, anfotericina B y equinocandinas, respectivamente. C. parapsilosis y C. tropicalis no registraron resistencias a fluconazol y voriconazol. Todos los aislamientos de C. glabrata fueron sensibles dosis dependientes a fluconazol y todos los aislamientos de C. krusei resultaron sensibles a voriconazol. La portación oral de Candida spp. resistentes a azoles podría llevar a fracasos terapéuticos en pacientes con VIH que desarrollen candidiasis orofaríngea.

Published: December 2021

La retención y sobrevivencia de microorganismos orales (MO) en la bombilla para tomar infusiones representa una posible fuente de contaminación de la boca, principalmente en personas con enfermedades periodontales. El objetivo del trabajo fue identificar la presencia de bacterias en bombillas para infusiones y en cavidad oral de pacientes con salud periodontal y antecedentes de enfermedad periodontal. Este fue un estudio observacional, descriptivo de corte transversal con componente analítico. Los participantes del estudio se agruparon en G1 (pacientes con salud periodontal, bombillas estériles para infusiones, con oxido etileno para su uso por 30 días) y G2 (pacientes con antecedente de enfermedad periodontal, bombillas estériles para infusión, con oxido etileno para su uso por 30 días). Participaron del estudio 50 pacientes. En los pacientes sanos (Grupo1) el promedio de Unidades Formadoras de Colonias (UFC) fue de 676± 226, mientras que en los pacientes con enfermedad periodontal (Grupo 2) el promedio de UFC fue de 817± 345. En los pacientes sanos (Grupo1) el promedio de MO fue de 668± 165, mientras que en los pacientes con enfermedad periodontal (Grupo 2) el promedio de MO fue de 774± 156. Se evidencia la presencia de microorganismos en bombillas para infusiones y en cavidad oral de pacientes con salud periodontal y antecedentes de enfermedad periodontal. El recuento de UFC presentes en la cavidad oral de los pacientes con salud periodontal y antecedentes de enfermedad periodontal fue similar.
Urban employment in post-transition economies: skill mismatch in the local labor market
Authors: J. Stanković Jelena , Džunić Marija , Marinković Srđan
Published: December 2021

The paper explores the mismatch between the skills and qualifications required by the labour market and those acquired through education and on-the-job learning. The skill mismatch in transition economies tends to be even more pronounced as the labour markets in these countries are characterized by structural unemployment, affecting both older workers with obsolete skills and the young ones. Employers face poor incentives for investing in workforce skill development, due to the inadequate investment climate and volatile business environment. Transition countries face increasing outward mobility of an educated workforce, loss of human capital, and shortage of workforce in the fields such as ICT, medicine, science and research. The research is based on empirical data generated in a survey on ICT and manufacturing enterprises in the City of Niš, Serbia. The research methodology combines workers' self-assessment method for the skill gap measurement and the competence approach combined with the statistical methods. The findings indicate the presence of a qualification mismatch, in the form of the over-qualification as a dominant irregularity in the analysed labour market. The results of the study are expected to contribute to creating a network of policy instrumentaria that tend to be effective on a sub-national level in addressing the mismatch.

Published: December 2021

The current study investigates how attitudes towards digital transformation and personal innovativeness affect the acceptance of emergency remote learning in the COVID-19 pandemic environment. The pandemic has affected all aspects of societies across the globe, including higher education that was also a significant push-up factor for the digital transformation of higher education. Thus, the main aim of this paper is to investigate the factors affecting emergency remote learning acceptance among the higher education students in Bosnia and Herzegovina (BiH). The results presented in this paper gained from a study carried out among higher education students in BiH cover the period of April – July 2020 via the open-source platform. The study focused on the students’ attitude towards a digital transformation is a significant factor in accepting emergency remote learning. Also, the personal innovativeness score has proven to be a crucial factor for adopting this new learning setting, i.e., more innovative students have a greater emergency remote learning acceptance than students with a lower personal innovativeness score. Hence, this study pinpoints the necessity of changing the attitudes towards technology applications in education. It would increase the usage of remote learning services and provide students with knowledge and skills for the new labour market
Examining the factors of influence on avoiding personalized ads on Facebook
Authors: Dobrinić Damir , Gregurec Iva , Dobrinić Dunja
Published: December 2021

Ad personalization is becoming the dominant promotional tactic, further enhanced by new technologies applications. Greater efficiency is the main goal of such an advertising approach, but it can cause the appearance of the so-called “privacy paradox” that can induce negative consumer reactions in terms of avoiding such ads. This paper investigates the factors influencing the avoidance of personalized ads communicated through the social network Facebook. Part of the research model deals with the impact of perceived personalization, perceived irritation, and perceived privacy concerns on skepticism towards advertising and advertising avoidance. Furthermore, the empirical research was conducted on data collected through the Facebook and WhatsApp mobile applications.

Five different distributions and metaheuristics to model wind speed distribution
Authors: WADI Mohammed
Published: December 2021

This paper presents a comprehensive empirical study of five distribution functions to analyze wind energy potential: Rayleigh, Weibull, Gamma, Burr Type XII, and Generalized Extreme Value. In addition, two metaheuristics optimization methods, Grey Wolf optimization and Whale optimization algorithm, are utilized to determine the optimal parameter values of each distribution. Five error measures are investigated and compared to test the accuracy of the introduced distributions and optimization methods, such as mean absolute error, root mean square error, regression coefficient, correlation coefficient, and net fitness. The Catalca site in Istanbul, Turkey, was selected to be the case study to conduct this analysis. The obtained results confirm that all introduced distributions based on optimization methods efficiently model wind speed distribution in the selected site. Although Gamma distribution based on GWO and WOA outperformed other distributions for all datasets at all heights, it was the worst in terms of computation complexity. Rayleigh distribution occupied the latest rank, but it was the best in terms of computation complexity. MATLAB 2020b and Excel 365 were used to perform this study.

Increase in the surface temperature of Photovoltaic (PV) module affects its efficiency and life adversely. This relationship between efficiency and surface temperature of a PV module is defined as the temperature coefficient. Since solar parks are long-life projects, a small drop in efficiency of modules might result in a significant reduction in overall power output for large projects making this option unfeasible, for both economical and energy yield perspectives. This loss in power can be reduced by cooling of PV modules. A hybrid Photovoltaic and Thermal system (PV/T) was developed in this study to investigate the impact of this system on overall efficiency. In addition to producing electrical energy, the heat gained by the circulating fluid was utilized for domestic usage. A critical temperature of the PV module was identified in this study beyond which the drop in efficiency was higher than the temperature coefficient. This critical temperature was noted to be a function of radiation intensity and decreased with decreasing intensity. Incorporation of the cooling system resulted in a decrease in surface temperature of the module by 20% with an increase in electrical efficiency of up to 2.3%. The overall efficiency of the PV/T system of at least 70%, with a maximum overall efficiency of 85% was observed at different radiation intensities, making this system a viable alternative to the conventional PV or thermal systems being used currently.

Thermal imaging has its own rapid change and development, both in theory and application. Starting from their military research extended to different real-life applications. This work represents the thermal topographical maps of the thermal image based on the direct projection for material thermal inspection. The test set here uses a square cross-sectional shaft that has been heated to around 200 o C and then measures 9 projections angle of 45o thermal images with an infrared (IR) thermal camera. The final thermal images were analyzed and rearranged to understand the thermal behavior of the shaft with the aid of cooling. The results show that a local slice C_22 indicates twice times in two different projections (2 and 9) with significant differences in temperature with respect to the real measured values. Also, layer C_28 shows the highest temperature difference before about 2.51 o C in projection 4 more than all the other layers. These represent an abnormal behavior for the slices or the local positions mentioned above, which may need more mechanical inspection to confirm the results. The mechanical topographical specifying the projection and slice position will increase the percentage of correctness of local and global assessments for test samples.

Railway transportation plays a significant contribution to carrying passengers in India. In which during the journey, pantry cars are involved to serves the food to all onboard passengers. The kitchen atmosphere of the pantry car gets very hot and humid during cooking which could affect occupants’ thermal comfort. Therefore, the current research article describes a review of the factors affecting human thermal comfort inside the kitchen of the railway pantry car. The factors influencing of human thermal comfort inside pantry car kitchens are classified into two categories viz; environmental factors that include “air temperature, mean radiant temperature, relative humidity, air velocity” and personal or individual factors including “metabolic rate and clothing insulation”. All these factors need to be considered in order to achieve the optimum level of thermal comfort inside the kitchen environment of the pantry car. With the assistance of all these factors, we can estimate the thermal comfort indices such as; SET “standard effective temperature,” PMV “predicted mean vote,” PPD “predicted the percentage of dissatisfied,” thereby recognizing the acceptable thermal sensation range for occupants’ (chefs) in the pantry car kitchens during the work period. These kinds of parametric studies can cover a wide group of all pantry car chefs in evaluating thermal comfort. Furthermore, there is a need to apply all the consequences of this research to increase the chef ’s thermal comfort inside the pantry car kitchen while working.

COVID-19 is a severe acute respiratory infection affecting worldwide population. There are many cases of complications after the COVID exposure occurring nowadays. One among is Post-COVID-19 Multisystem Inflammatory Syndrome in Children (MIS-C). As per CDC report till March 1, 2021, 2617 cases of MIS-C were meeting the definite case criteria and among 33 death cases were reported. Here we report a case of COVID-19 associated Multi-system inflammatory syndrome in a child (MIS-C) interpreted with WHO case definition criteria.

The patient was a 7-year-old boy, with initial presentation of moderate fever, non-itchy red blanching rashes, breathlessness, later progressed to cardiogenic shock accompanied by positive SARS-CoV-2 antigen result.

The emergency cardiogenic shock treatment protocol was followed with initial stabilization and resuscitation strategy. He was successfully managed by three days of IV Immunoglobulin 2g/kgand Methylprednisolone 2mg/kg/day therapy along with other supportive treatments. The patient was discharged after 20 days of hospital stay with improved health condition.

Our case report will strengthen the exposure-outcome relations between the coronavirus infection and MIS-C, moreover the strategies carried out in our case will be a future direction for the effective management of MIS-C.
