Prevalence of Kinesiophobia in Post Spinal Surgery Patients
Authors: Bhise Dhanashree , Palkar Anagha , Kumar Ajay
Published: October 2021

Background: The spinal column is a highly complex system of bones and connective tissues that provide support for the body and protect the delicate spinal cord and nerves. Back surgery carries higher risks than some other types of surgery because it is done closer to the nervous system. The most serious of these risks include paralysis and infections. Fear of movement/(re)injury is described as “a specific fear of movement and physical activity that is (wrongfully) assumed to cause reinjury”. In the extreme situation of fear of movement, the expression “kinesiophobia” is used. Tampa Scale for Kinesiophobia (TSK) was developed by Miller, Kori and Todd 1990 in order to assess fear of movement/(re)injury. It is a valid, reliable tool is used to assess Kinesiophobia.(1)
Aim: The present study was done to Assess Prevalence of Kinesiophobia In patients undergone Spinal Surgery using Tampa Scale (6- 10 weeks post surgery).
Method: In this study a total of 100 patients answered Tampa scale of kinesiophobia and were evaluated according to their level of kinesiophobia after post spinal surgical period 6- 10 weeks, that is after the healing period.
Result: There was a high degree of kinesiophobia which was observed after post spinal surgical period 6-10 weeks in 61% of the participants.
Conclusion: This study showed Prevalence of High Degree of Kinesiophobia noted after 6-10 weeks in 61% of the Post- Spinal Surgery patients even after 4-6 weeks of healing period.

Key words: Kinesiophobia, Fear-avoidance, Spinal surgery, Tampa scale.

La cartographie de l’occupation du sol du Gabon en 2010 et 2015 et celle des changements entre ces deux dates a été réalisée dans le cadre du programme OSFACO [1] par l'Agence Gabonaise d'Etudes et d'Observations Spatiales (AGEOS). Il s’agit de la première carte d’occupation du sol de référence à l’échelle nationale dont la légende est issue d’une concertation des acteurs majeurs du secteur forestier gabonais. Cette carte a été obtenue en affinant celle du couvert forestier du Gabon (forêt/non forêt) obtenue dans le cadre des projets OSFT [2] et GEOFORAFRI [3]. La cartographie s’est basée sur l’utilisation des images satellitaires SPOT 5/7, Sentinel 2 pour l’année 2015 et les images SPOT 4, ASTER et ALOS 1 pour l’année 2010. Les méthodes de classification semi-automatisée et d'amélioration manuelle ont été combinées pour une meilleure précision des classes d’occupation du sol. Les résultats obtenus mettent en évidence 10 classes d’occupation du sol représentant les grands ensembles paysagers du pays, dominés par les forêts qui occupent 89% de la superficie totale du Gabon en 2015. Les classes d’occupation du sol qui ont le plus évolué entre 2010 et 2015 sont les forêts, les savanes, les terres agricoles et les surfaces artificialisées. Les principales pertes en forêt sont liées à la conversion des forêts vers les surfaces artificialisées, les terres cultivées et les sols nus. Les gains en forêt les plus importants quant à eux sont observés au niveau de la fermeture des pistes forestières. La validation du produit, réalisée par une équipe indépendante de celle qui a produit la carte, s’est basée sur une donnée de référence issue d’un plan d’échantillonnage combinant une composante systématique et aléatoire suivant la méthodologie de Sannier et al. (2016). L’analyse de la correspondance entre la donnée d’occupation du sol produite et la donnée de référence a permis d’estimer la précision globale à 95%.

Published: October 2021

Effects of reading aloud beyond language: self-regulation as a mediator Reading aloud is a family activity which, if carried out frequently in the first years of life, supports the child’s linguistic and alphabetic development. Being a social process, shared reading in the family improves the child’s psychosocial development and parenting skills. It has recently been shown that cognitive and linguistic stimulation are associated with an improvement in self-regulation skills. This article describes the most recent findings on the importance of conversation during shared reading and the relationship of this activity with self-regulation and parenting.

Not-so-typical typical atrioventricular nodal re-entrant tachycardia in an adolescent
Authors: JS Ang
Published: October 2021

Dysrhythmias are commonly encountered in the Emergency Department (ED). Timely management and recognition of dysrhythmia in the ED is essential and crucial. Physicians working in the ED should be familiar with atypical presentation of common dysrhythmias. This case report illustrates atrioventricular nodal re-entrant tachycardia (AVNRT) with an unusually slow heart rate in an adolescent.

A 16-year-old male presented to the ED twice for palpitations. His electrocardiograms showed narrow complex tachycardia with absent P waves. Electrophysiology studies confirmed typical slow-fast AVNRT which was treated successfully with radiofrequency ablation of the slow pathway.

Diagnosing rare dysrhythmias or common dysrhythmias which manifest atypically can be challenging for non-cardiologists. Although AVNRT generally occurs with a heart rate of >130 bpm, emergency physicians should be aware that AVNRT can take place with a relatively slower rate in both the elderly and young.

Published: October 2021

Background: Traumatic hemothorax is a common consequence of blunt chest trauma. A hemothorax that is missed by initial chest X-ray, but diagnosed by computed tomography (CT), is known as an occult hemothorax. The present study aims at investigating the clinical outcomes of conservative management of occult hemothorax in mechanically ventilated trauma patients. Methods: A retrospective study of all adult blunt chest trauma patients with occult hemothorax requiring mechanical ventilation in a level 1 trauma center was conducted (2010- 2017). Data were obtained from the trauma registry and electronic medical records. Patients were categorized into (a) successful conservative treatment group, and (b) tube thoracostomy group. Results: During the study period, 78 blunt chest trauma patients who had occult hemothorax required mechanical ventilation. Occult hemothorax was managed conservatively in 69% of the patients, while 31% underwent tube thoracostomy. The main indication for tube thoracostomy was the progression of hemothorax on follow-up chest radiographs. Comparison between groups showed that pulmonary contusions (59% vs. 83%), bilateral hemothorax (26% vs. 58%) and chest infections (9% vs. 29%) were lower in conservatively treated group (p < 0.05). Length of stays in ICU and hospital were also lower (p < 0.05). Longer duration of mechanical ventilation and maximum PEEP were signiﬁcantly associated with tube thoracostomy. Overall mortality was 12% and was comparable between groups. Conclusion: Mechanically ventilated patients with occult hemothorax following blunt chest trauma can be managed conservatively without tube thoracostomy. Tube thoracostomy can be restricted to patients who had evidence of progression of hemothorax on follow-up or developed respiratory compromise.

Hemoglobin Levels and Postoperative Outcome in Pediatric Surgical Patients
Authors: Kumba Claudine
Published: October 2021

Background: Postoperative outcome in children is multifactorial. Among the reported predictors of postoperative outcome, preoperative anemia has been related to adverse outcome in children. A secondary analysis was undertaken to determine the correlation between hemoglobin levels and postoperative outcome in children included in a cohort of an observational pediatric study published previously since this analysis has not been done. Objective: To determine the correlation between preoperative, intra-operative, postoperative hemoglobin levels and postoperative outcome in children in neurosurgery, abdominal and orthopedic surgery. Methods: Secondary analysis of a sub-cohort of 252 pediatric surgical patients with a median age of 62 months [12.50-144.00]. Results: Preoperative hemoglobin levels were negatively correlated to length of stay in the intensive care unit (LOSICU) (p=0.002), to length of hospital stay (LOS) (p<0.0001), to the number of patients with intra-operative and/or postoperative complications (p<0.0001) and to re-surgery (p<0001). Low preoperative hemoglobin levels below 6g/dL were correlated to higher postoperative LOSICU and LOS. Intra-operative hemoglobin levels were negatively correlated to LOS (p<0.0001) and to the number of patients with intra-operative and/or postoperative complications (p=0.004). Low intra-operative hemoglobin levels below 5g/dL were correlated to higher LOS. Postoperative hemoglobin levels were positively correlated to LMV (p=0.002). Conclusion: Hemoglobin levels are among other multifactorial predictors of postoperative outcome in pediatric surgical patients emphasizing the importance of a global patient blood management implementation program to improve outcome in surgical children.

The process of extracting gold using mercury (Hg) carried out by Nusa Halmahera Minerals industries (PT. NHM) as well as by the community of illegal gold mining or gold mining without a permit (PETI) that occurs in the mining area of ​​Halmahera Island can have a negative impact on the aquatic environment. This study aims to determine the mercury absorption in mangrove roots of Rhizopora sp and Telescopium telescopium at two different stations. Sampling of mangrove roots was repeated 3 times for each station. Differences in the accumulation of heavy metals Hg in the roots of Rhizophora sp were analyzed using the T-test. The study showed that the concentration of mercury in the roots of Rhizophora sp ranged from 0.016 – 0.026 mg/kg and there were differences in root absorption between Rhizopora sp at station 1 of the Tabobo River mangrove near the PETI disposal and station 2 at the mining industry waste disposal. The concentration of mercury in Telescopium telescopium ranged from 0.08 - 0.15 mg/kg.  It is indicates that Telescopium telescopium in Kao Teluk has been contaminated with mercury but is still below the threshold of the quality standard that has been set.

Authors: Silva Teomar Duarte da , Souza Michele Trombin de , Souza Mireli Trombin de , Cipriano Roger Raupp , Bizzo Humberto Ribeiro , Deschamps Cicero
Published: October 2021

The restinga is an Atlantic Forest ecosystem characterized by tree, shrub, and herb species that are rich sources of essential oils. In this study, we aim to quantify the essential oil content and determine the chemical constituents of fresh leaves of 14 plant species in a restinga stretch in southern Brazil. Essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to mass spectrometry. Campomanesia reitziana, Cortaderia selloana, and Sophora tomentosa had no essential oils. Total essential oil content ranged from 0.01% (Mikania involucrata) to 1.56% (Varronia curassavica). In total, 60 chemical constituents were identified, representing between 46.2% and 96.5% of the chemical composition of the essential oils. Limonene was the common constituent in all species in which the essential oils were present. The major constituents were ar-curcumene (15.1%) and cis-chrysanthenol (14.2%) in Ambrosia elatior; benzyl benzoate (43.5%) and benzyl salicylate (23.7%) in Aniba firmula; caryophyllene oxide (35.7%) and spathulenol (10.6%) in Austroeupatorium inulaefolium; spathulenol (19.8%) and caryophyllene oxide (14.0%) in Baccharis spicata; caryophyllene oxide (16.3%) in Eugenia astringens; curzerene (30.0%), limonene (13.0%), and germacrone (11.9%) in Eugenia uniflora; caryophyllene oxide (17.1%) and ledol (11.3%) in Lantana camara; caryophyllene oxide (27.7%) and limonene (12.7%) in M. involucrata; 1,8-cineole (19.8%) in Psidium cattleianum; limonene (10.2%) in Schinus terebinthifolius, and allo-aromadendrene (15.2%) in V. curassavica. We expect that our results can assist in selecting species of potential interest for herbal, phytotherapeutic, and cosmetic products.

Published: October 2021

Pigeon pea is an important source of protein for smallholder farmers in South Africa. The average seed yield per hectare ranges from 0.5 to 1 tonne due to the use of un-improved varieties that succumb to both biotic and abiotic stresses. Understanding the relationship between seed yield and agronomic traits in a genetically diverse germplasm collection is a prerequisite for developing an efficient selection and breeding program. This study determined the relationship between seed yield and agronomic traits to identify key traits for selection. Two separate experiments involving seven short and six medium duration pigeon pea genotypes were planted in a randomized complete block design (RCBD), each with three replications. Agronomic traits, including yield and its components’ genotype mean data was subjected to correlation, path coefficient and stepwise regression analyses. The results showed a strong positive and significant correlation between number of pods per plant and seed yield in both medium and short duration genotypes. The number of pods per plant had a high direct effect on seed yield in both medium and short duration with values of (0.43) and (0.63) respectively. Number of branches and pod length exhibited high direct effect (0.30-0.99) for medium duration. However, seed yield per plant was an important predictor of seed yield in short duration while seed yield per plant, 100 seed weight and number of seeds per pod were key predictors of seed yield in medium duration genotypes. Therefore, these traits should be targeted for seed yield improvement in Pigeon pea.
Which Modality Should Be Integrated to Increase the Diagnostic Efficiency of BI-RADS 0, 3, and 4 Lesions? Ultrasonography or Digital Breast Tomosynthesis?
Authors: Arslan Zeynep Fatma , Altunkeser Aysegul , Aksoy Nergis , Korez Muslu Kazım , Omeroglu Ethem
Published: October 2021

Background: Digital mammography (DM) is one of the most common and effective radiological methods for breast cancer screening and detection. A dense fibroglandular breast tissue can lead to false negative results by superimposing on the lesion margins. Therefore, adjunctive imaging methods, such as digital breast tomosynthesis (DBT) and ultrasonography (US), are needed to increase mammographic sensitivity. Objectives: This study aimed to examine the contribution of US and DBT to DM in different patient groups (patients group of breast imaging-reporting and data system [BIRADS] 0 and 3-4 lesions, patients with dense breast parenchyma, patients with non-dense breast parenchyma).. Whether US and DBT can upgrade or downgrade the BI-RADS category of uncertain lesions detected on DM was also investigated. Patients and Methods: Forty-six patients, who were classified as BI-RADS categories 0, 3, and 4 in DM, according to DBT and US findings, were included in the study. DM followed by DBT was performed for the patients, and the BI-RADS classification system was applied. Subsequently, the patients were evaluated sonographically, and the BI-RADS system was applied according to the US results. Each BI-RADS category was compared with the histopathological and multimodality follow-up results. The diagnostic performance of all modalities was also examined alone and in combination. Results: The sensitivity and specificity of DM alone was 42% and 87%, respectively. DBT detected the lesions with 92% sensitivity and 68% specificity. The modality with the highest sensitivity for the detection of malignant lesions was US (100%). Besides, the specificity of DBT was significantly high for dense breasts (P < 0.001). There was no significant difference in terms of the diagnostic accuracy of US measurements between dense and non-dense breasts. For indeterminate lesions, the integration of DBT and US to DM increased the diagnostic accuracy. Conclusion: The contribution of DBT is more valuable than US in patients with dense breast parenchyma.

The authors show the need and some existing opportunities for analysis of non-traditional data sources to obtain a complete and more relevant picture of industries spatial development. The research methodology includes the use of text mining for economic and geographical studies. The relevance of the research is determined by insufficient completeness of official statistical data, cheapening

of relevant information processing technologies and abundance of large text data sources in open access. The article discusses the role of the pulp and paper industry (as a key part of the timber industry) in economic and spatial development of modern Russia. The authors identify main trends in the economic and spatial development of the pulp and paper industry of European Russia, draw the conclusions on the expected industry trends and give recommendations for strategic management decisions to respond to industry challenges. The authors claim that the industry needs liberalization and stabilization, primarily through moratoriums on policy changes. The role of the use of big data, and in particular of text mining in economic and geographical research for reasonable and objective conclusions formation that can be used to make timely and balanced management decisions in the timber industry and the pulp and paper industry, is emphasized.

Authors: Baklanov P.Ya. , Ushakov E. A.
Published: October 2021

The article describes the features of the socio-economic situation of Sakhalin Oblast, its development trends since the 1990s, both general and territorially differentiated ones. The economic and geographical position of the region with allocation of conditional market zones, including foreign destinations, is considered. Data on the state and dynamics of the main socio-economic indicators of the region, as well as its place in the Far Eastern Federal District by these indicators are provided. The dynamics of the population of the region is shown. The oil and gas industry and gas processing make a basis of the modern economy of the region that stipulates high values of the socio-economic indicators. Favorable and unfavorable factors that can affect the long-term development of the region are highlighted. The comparison of Sakhalin Oblast with other constituent entities of the Russian Federation is carried out using the proposed integral coefficient of the ratio of socio-economic indicators. The levels of the development in all municipal districts were assessed by 7 different socio-economic indicators. The large territorial differences in nearly all individual socio-economic indicators were revealed. Based on the scoring of all socio-economic indicators, the districts were grouped according to their general level of the development. These assessments also showed significant intra-district socio- economic differentiation. Taking into account a number of available favorable prerequisites, the regional development program and scientific proposals for diversification of the economic development of the region, the priority economic activities were summarized; and the role of the territories of advanced development (TADs) being created in the region was shown. Some conclusions were made about the role of the prerequisites in location of priority activities in many areas of the region.
Disparities of China’s regions development: dependence on the sectoral economic structure
Authors: Zakharzhevskaya A.Yu.
Published: October 2021

The article explores the dynamics of changes in disparities of China’s regions’ economic level. According to a number of researchers, economic disparities between China’s regions started to decrease from about the mid-2000s. To clarify this picture the article uses indicator of contribution of the region’s GRP to the country’s total GRP. As a result of the research carried out by the author, it was found that in the PRC there really was a period when the economic gap between regions was narrowing down, but in general, changes in the relative contribution of regions to the country’s GRP are more complex than just a decrease or increase in economic disparities. Also, based on statistical data, the article draws conclusions about the relationship between the dynamics of the region’s contribution to the total GRP and the shares of the secondary and tertiary sectors in the region’s economy. It turned out that the increase in the economic level of the region in comparison with other regions is closely related to the share of the secondary sector in the GRP of this region: in most regions of China, the increase in the share of the secondary sector occurs in parallel with the growth of the contribution of the region’s GRP to the total GRP of the country. The growth in the share of the tertiary sector, on the contrary, in most cases is accompanied by a relative decrease in the economic level of the region, that is, its contribution to the total GRP decreases.

Published: October 2021

To solve demographic problems and, in particular, to increase the life expectancy in Arctic regions, analysis of mortality in small territories is of particular relevance. The object of this study is to analyze the intraregional differentiation of mortality based on age-standardized indicator of lost years of life caused by premature mortality in the context of main classes of death’s causes for the period 2010- 2019 in Arkhangelsk region. The standardized indicator of lost years of life has decreased for all ages and all classes of death’s causes in Arkhangelsk region. Dynamic and level of the standardized indicator of lost years of life have big differentiation at municipal level. For example, in urban districts and adjacent areas the reduction in mortality was bigger than in border and peripheral areas. Our study shows that in the structure of lost years of life the first place is occupied by diseases of circulatory system (50.0%), the second – by external causes (19.7%), and the third – by neoplasms (14.3%). The most difficult situation is in the peripheral areas of the region due to higher losses from external causes of death at working age.
Evolution of concepts of spatial segregation in US cities
Authors: Alov I.N.
Published: October 2021

Spatial segregation has been and still remains a popular object of study among city researchers representing geography, sociology, and economics. The core of the corpus of conceptual works on this subject is composed of works devoted to US cities. Russian and Western European researchers in their works usually either use or criticize the American experience. However, at the moment in the domestic literature there is no comprehensive review of conceptual approaches to the study of the segregation of American cities. Over the almost 100-year history of this direction, theoretical and methodological approaches have changed several times. This article provides a review of thematic literature on American cities over the entire period of study of this phenomenon. There are six main stages in the development of this research field. These include the work of the Chicago School, quantitative studies of segregation as a social problem, original ideas from radical and critical geographers, concepts based on the notion of the racial hierarchy of society, publications of the Los Angeles School and theorists of polarization, as well as the two most recent major concepts. spatial segregation – «quartered city» by P. Marcuse and hyperghettoization by L. Wacquant. The key positions on which the representatives of these directions do not converge are highlighted - the reasons, driving forces and the nature of the segregation process. The logic of the change of prevailing views is traced and conceptual additions are identified.
A multi-scale approach to the study of spatial inequality of population income in Brazil
Authors: Gladkiy A.S.
Published: October 2021

The aim of the research is to identify the key features of spatial inequality of income distribution in Brazil and its representation on different spatial scales: on the regional, state or municipal level, as well as special statistical grids (mesoregions and microregions). The economic development of Brazil in the beginning of the XXI century is characterized by reducing of the level of income inequality, as well as a certain decrease of the level of spatial inequality between the southern and northeastern regions. The common rule is that the heterogeneity of income distribution gradually increases from top to the lower levels of spatial division. The analysis of inequality measures has proven that despite of the general decrease of regional inequality in 2000–2010, the lower levels of territorial division have shown the lowest progress in reducing regional inequality. The paper also proposes the ways to illustrate spatial inequality when applying polyscale method, based on mapping the variation of average population income in Brazil on different scale levels.

Geographical descriptions and geographical comparisons provide a basis for understanding the key features of a place. These classical approaches, revealing the typical and the unique, make it possible to discover the «formula of the place», to understand the rational directions of the development of the territory. Often, territorial development projects are based not on marketing and technical calculations, but on a geographic idea. In this case, we are dealing with conceptual geography, which can significantly change the priorities of society’s development in the future. Conceptual geography is seen as an applied approach, expressed in the practical, economic design of geographical thought. The tourism sector demonstrates a special geographical conceptuality. Tourism is one of the areas of interest for people where the importance of geography is recognized. The most promising planning of tourist routes based on geographical creativity. The tourist industry is especially «genetically» territorial. Objects of tourism and recreation are inherently geographic, organically integrated into the territory, reflecting its features. The article shows the movement from descriptive and comparative geography to conceptual geography on the example of the development of one of the towns of the Perm region. Geographic technologies are actively used in tourism design. The development of conceptual geography through tourism testifies to its special sensitivity, to the ability to show new guidelines for social development.

Published: October 2021

The present investigation provides one of the first complex attempts of theorizing on changes in tourism sector activity within COVID-19 quarantine. Drawing from system and criterion approach weusedthe analysis of official documents and news publication to identify 8 international models of tourism sector support within the pandemic quarantine. Each model was considered with the instrument of strengths and weaknesses analysis. By reviewing Russian national model we conducted deeper analyses juxtaposing and describing experience of Russian regions. Drawing from aтopinion poll realized in Perm krai we described some special features of each tourism sector segment activity within COVID-19 pandemic quarantine. The opinion polls mentioned also showed some limitations of Russian tourism sector support model. With regard to the data mentioned, we proposed the concept of the national electronic exchange service of tourism and resort. This system will potentially support the Russian model in the condition of epidemic crisis, helping the national tourism sector to save and then to restore its activity following laissez-faire principle.
Breve histórico da gestão escolar na educação infantil a partir da constituição de 1988
Authors: Oliveira Eduardo Paiva
Published: October 2021

Até os anos de 1970, pouco ou quase e nada foi feito para que a legislação vigente garantisse a provisão de educação infantil. Somente nos anos de 1980 a sociedade civil organizada e grupos de pressão ligados a pauta da educação tiveram êxito na luta pela incorporação desse nível de ensino ao texto constitucional A educação, de uma forma geral, passa por um momento de significativas transformações em suas práticas e concepções de ensino. O objetivo do artigo é descrever, brevemente, aspectos da gestão e qualidade escolar da Educação Infantil após a Constituição Federativa de 1988, levando em consideração aspectos da gestão como um mecanismo de participação democrática. Para a realização da pesquisa foi utilizado o procedimento metodológico da revisão bibliográfica e documental. Compreende-se que a gestão na educação infantil, atualmente, é pautada por aspectos de colaboração participativa e valorização da formação continuada para que os profissionais da educação se adequem as novas demandas educacionais. Os esforços caminham para a integração do cuidar e educar como concepção integrante do processo educativo, buscando novas práticas pedagógicas que acompanhem o desenvolvimento da criança, considerando as suas peculiaridades, valorizando a diversidade para a compreensão do outro e do mundo, no objetivo de uma educação integral.

O presente trabalho analisar a importância do lúdico na educação infantil e sua importância no processo de ensino e aprendizagem.  A pesquisa retrata o lúdico e a caracterização do docente, por meio da perspectiva educacional, trazendo conceitos sobre seu papel sob a visão de diferentes autores. Para isso utilizou-se a abordagem qualitativa descritiva, por meio de uma pesquisa bibliográfica. Concluir-se que é preciso que o docente permita que através de jogos e brincadeira as crianças demonstre suas necessidades e habilidades, e aprendam os mais diversos aspectos do conhecimento, em uma atividade espontânea e imaginaria, enfatizando que jogos e brincadeiras são essenciais para o desenvolvimento da criança. Neste contexto ressalta-se que o ensino é construído pela criança e o docente que cria situações que gera confiança para que a criança construa seu próprio conhecimento. Assim, a criança aprende enquanto brinca e ocorre à descoberta de si mesmo e do outro, além de desenvolver e construir sua realidade, tanto pessoal quanto social, por meio das brincadeiras, registrando sua capacidade social com o auxílio principalmente do docente. Portanto, é preciso que na brincadeira as crianças recriam e estabilizam aquilo que sabem sobre os mais diversos aspectos do conhecimento, porque o brincar é importante e influência o seu desenvolvimento.

DEVELOPED EMPATHETIC CAPACITIES AS A PREREQUISITE FOR QUALITY INTERPERSONAL RELATIONSHIPS WITHIN A SCHOOL ENVIRONMENT
Authors: Maslovarić Biljana , Blečić Marijana , Cohen Shai
Published: October 2021

The specific issue of the quality of educational process requires a quality school environment, which can be observed at several levels: first of all, through quality interpersonal relationships, and then through quality curricula and syllabi and the ecology of the school environment (Relja, 2006). A quality school atmosphere is based not only on а humane/altruistic approach to students but also on the satisfied teacher, who is characterised by a number of positive qualities, as well as on the equally satisfied student, who cultivates positive feelings towards the authority of their teachers, towards the school itself, and towards the educational process in general. Good quality relationships between people are based on empathy, which is an ability to relate to the feelings of other people. It is via empathy that the teacher, however briefly, puts on their students' shoes and thereby feels the same emotions, which is what actually allows them to truly understand their students' feelings, actions, and problems and to respond positively to them. In doing so, they show a full understanding of their needs directed towards the well-being of students. Empathy includes both cognitive and emotional components and, therefore, in the process of empathising, knowledge and emotions interact. As most authors consider it to be a regulator of different forms of behaviour, especially within the context of altruistic behaviour (Batson, Duncan, Ackerman, Buckley, and Birch, 1981), empathy represents very important kind of motivation for altruism, given the degree of emotional unity established, which is a prerequisite for effective and sincere interaction between people and an initiator of a close understanding of another person's emotional world.

Образовање и учење директно утичу на дјететову будућност у животу. Управо је то разлог непрестаног преиспитивања садашњег васпитно-образовног система, односно промишљања о томе који видови учења и поучавања позитивно доприносе будућности дјетета, а који не. Иза необичног наслова књиге Усмјереност на овладавње ауторка нас увјерава да процес изградње самопоуздања и самоусмјерености у процесу учења доприноси успјеху сваког дјетета. При томе, нагласак није на квантитативним показатељима успјеха, оцјени и материјалној награди, већ на истинском квалитету, поштовању најважнијих животних вриједности и обогаћивању личности дјетета. Успјех је јединствен, као и сам процес учења, али је обликован друштвеним контекстом у коме се егзистира. То је разлог више, упозорава нас ауторка, да у времену великих друштвених промјена и убрзаног развоја науке и технологије развијемо моделе рада са новим генерацијама које ће их спријечити у опсједнутости информационом технологијом.

Fibrinogen is essential for blood coagulation. The C-terminus of the fibrinogen α-chain (αC-region) is composed of an αC-domain and αC-connector. Two recombinant fibrinogen variants (α390 and α220) were produced to investigate the role of subregions in modulating clot stability and resistance to lysis. The α390 variant, truncated before the αC-domain, produced clots with a denser structure and thinner fibres. In contrast, the α220 variant, truncated at the start of the αC-connector, produced clots that were porous with short, stunted fibres and visible fibre ends. These clots were mechanically weak and susceptible to lysis. Our data demonstrate differential effects for the αC-subregions in fibrin polymerisation, clot mechanical strength, and fibrinolytic susceptibility. Furthermore, we demonstrate that the αC-subregions are key for promoting longitudinal fibre growth. Together, these findings highlight critical functions of the αC-subregions in relation to clot structure and stability, with future implications for development of novel therapeutics for thrombosis.

Many researchers during several decades have proved that sleep is a key factor for enhancing performance in sports. Henceforth, this study is to investigate the impact of a mobile phone on changes in athletes sleep behaviour because of COVID-19 lockdown in India. For which, the survey conducted among 550 sports persons representing various Universities (300 male/250 female) across various states of India using simple random sampling technique, and Sleep Quality Assessment (PSQ: Pittsburgh Sleep Quality Index) was used to find out the level of sleep disturbance in athletes. The composed data were analysed using a percentile. The results of this study showed that the mobile phone usage during COVID-19 lockdown in India out of 550 athletes’ data was collected in which 6.4 ⸓ of athletes with a score of 4 in the scale were not distracted due to COVID-19 lock down they underwent regular sleeping schedule there was no change in their circadian rhythm, 40.4 ⸓ of athletes with a score of 6 which means there was a high level of distraction in sleep due to COVID-19 lock down and 23⸓ of the athletes suffered a very high level of sleep destruction during COVID-19 lock down. Which showed a changed sleep behaviour of sports persons.

Conclusion and Recommendations: Lack of exercise during COVID-19 lockdown changed the sleep behaviour in athletes. Which made an addiction towards mobile phone usage. This study concludes that regular exercise enhances sleep and also keeps athletes from over usage of mobile phones.
