Biomimetic hydroxyapatite (HAP)/ Carboxymethyl Cellulose (CMC) composite materials for bone tissue engineering applications
Authors: Saha1 Nirmal , Bhadra Debabrata
Published: November 2020

Natural bone is a complex material with a well-designed architecture. To achieve successful bone integration and regeneration, the constituents and structure of bone-repairing scaffolds need to be flexible and biocompatible. Hydroxyapatite (HAp), the main constituent of bone minerals,
has excellent biocompatibility, while carboxymethyl cellulose (CMC), comprised of a three-dimensional network, has high flexibility. Therefore, CMC/HAp composites have attracted attention for the advancement of bone tissue engineering. In this work, a carboxymethyl cellulose/hydroxyapatite
(Ca10(PO4)6(OH)2; HAp) composite has been developed as a three dimensional scaffold for bone tissue engineering. Scanning electron microscopy revealed that the CMC/Hap composite had a sheet like structure. These results revealed that the amount of precipitated HAp in the CMC/HAp composites
was affected by the amount of CMC used during preparation. Properties of composites can be improved at optimal filler content compared to the pure Hap in the perspective of various biomedical applications. We have characterized the surface morphology of the composite using SEM image and having
with the observed well dispersion of Hap in the Cmc phase.
A Mini Review on the Corona Various- A Universal Long Standing Problem: T-Cell Therapy Might Show Some Light in New Vaccine Development
Authors: Santra Chitta Ranjan , Ghosh S
Published: November 2020

Stimulation of the body’s immune system might be important to cure many diseases. The induction of cellular immune responses has thus far received little attention in respiratory virus vaccine development. CD8 T cells are critical for mediating clearance following many acute viral
infections in the lung. In addition, memory CD8 T cells are also capable of providing protection against secondary infections. The present mini reviewed the present status of corona virus and was attempted to elucidate the future danger of corona virus. A suggestion for the development of
T-cell based therapies has been made to fight against Corona virus. The enhancement of immunity using T-cell therapy might show a new light in this regard. Because of genetic diversity and frequent mutational change, it appears to be difficult to find a permanent solution of the corona problem
in the near future. Vaccinations that solely promote the induction of neutralizing antibodies may not be optimal in providing protection against the corona virus respiratory infections, in particular. Therefore, human civilization is going to face unprecedented experiences, if not social and
individual cares are always maintained and common people understand the seriousness of the virus.

Energy System Modelling Challenges for Synthetic Fuels
Authors: Kim Seokyoung , Dodds Paul E. , Butnar Isabela
Published: November 2020

Long-distance air travel requires fuel with a high specific energy and a high energy density. There are no viable alternatives to carbon-based fuels. Synthetic jet fuel from the Fischer-Tropsch (FT) process, employing sustainable feedstocks, is a potential low-carbon alternative. A number of synthetic fuel production routes have been developed, using a range of feedstocks including biomass, waste, hydrogen and captured carbon dioxide. We review three energy system models and find that many of these production routes are not represented. We examine the market share of synthetic fuels in each model in a scenario in which the Paris Agreement target is achieved. In 2050, it is cheaper to use conventional jet fuel coupled with a negative emissions technology than to produce sustainable synthetic fuels in the TIAM-UCL and UK TIMES models. However, the JRC-EU-TIMES model, which represents the most production routes, finds a substantial role for synthetic jet fuels, partly because underground CO2 storage is assumed limited. These scenarios demonstrate a strong link between synthetic fuels, carbon capture and storage (CCS) and negative emissions. Future model improvements include better representing blending limits for synthetic jet fuels to meet international fuel standards, reducing the costs of synthetic fuels and ensuring production routes are sustainable.
Civil engineers’ role in saving the world: updating the moral basis of the profession
Authors: Francis Nick
Published: November 2020

Today’s civil engineering profession was born in the industrial revolution with the vision of ‘harnessing the forces of nature for the benefit of mankind’. However, the industry’s alarming environmental impact means that civil engineers must urgently change their impact on the world. Viewing the dangers of climate change through the lens of behavioural science, this paper identifies the four ‘levers’ that civil engineers must pull to put the profession on a sustainable and morally justifiable path. Three of the levers focus on behaviours, outlining measures that individuals, companies and institutions can take to realign decision making to the needs of sustaining life on the planet. Only one lever relates to new technological solutions. These levers offer a pragmatic to-do list of actions, to unlock systemic change, and thereby accelerate the profession’s transition to a net-zero future.
Tempo-spatial variability in volatile emissions from a sewage-treatment plant in Surat, India
Authors: Muradi Misaq Ahmad , Vaghani Minakshi
Published: November 2020

The purpose of this research work was to evaluate the Benzene, toluene, ethylbenzene and xylene (BTEX) emissions from a Bamroli sewage-treatment plant (STP) in Surat City, India. Tiger handheld gas detector was utilised to measure emissions of BTEX during three periods of monitoring, and sewage samples were collected to determine the characteristics of sewage. The spatial variation of BTEX was determined at various treatment units of the STP during the months of November and April and represented as interpolation maps using ArcGIS. Box charts were plotted to represent the temporal variation of BTEX, which categorise the resultant data on the basis of their frequency. It has been noticed from the interpolation maps that the concentration of BTEX decreases as sewage travels from the inlet to subsequent units. Approximately 50% of all readings obtained of BTEX concentration fall within 0.5 parts per million, which exceeds the limits stipulated by the National Ambient Air Quality Standards, 5 μg/m3 for benzene. It can be concluded that more vent pipes have to be provided for the dispersion of these compounds in transmission lines. Also, some safety aids such as face masks have to be utilised by labourers who are continuously subjected to these compounds.

Scène
Authors: Muller Bernard
Published: November 2020

Caractéristique de l’anthropologie culturelle et sociale, la notion de scène ne s’arrête pas essentiellement au monde du spectacle. À travers une approche historique et comparative, nous remarquons que dans le quotidien l’être humain adopte des comportements qui sont propres à la scène. Au-delà d’une simple métaphore, comme elle fut utilisée par des auteurs classiques, la scène est également un terrain de recherche à part entière dans laquelle l’anthropologue serait le dramaturge.

Interculturalité
Authors: White Bob
Published: November 2020

L’interculturalité désigne le contact entre acteurs de diverses provenances. Malgré que l’anthropologie ait eu une influence considérable sur la recherche en communication interculturelle, elle s’est toutefois tenue à l'écart de cette discipline. La pensée interculturelle n’a par ailleurs pas de véritable foyer disciplinaire et fait l’objet d’une diversité d’approches, de concepts et de finalité. Trois thèmes sont cependant récurrents à travers les travaux sur les dynamiques interculturelles : la bidirectionnalité, les préjugés et les compétences.

Children’s and Parents’ Perceptions of Online Commercial Data Practices: A Qualitative Study
Authors: Desimpelaere Laurien , Hudders Liselot , Sompel Dieneke Van de
Published: November 2020

Children’s personal data are often collected for commercial aims. Although regulations in different countries aim to protect children’s privacy (e.g., by imposing websites to request parental consent for the processing of children’s data for commercial purposes), concerns about protecting children’s online data continue to rise. This article therefore aims to get insights into parents’ and children’s privacy coping strategies and perceptions underlying these strategies. In-depth interviews with ten parents and nine children (8–11 years) were conducted. Findings show that although children engaged in avoidance (e.g., leaving the particular website) and confrontation (e.g., seeking support) strategies, they mainly did this to protect their privacy from malicious individuals—and not from commercial parties. Participating children also lacked general knowledge about both explicit and implicit data practices. To protect their children’s privacy, parents in this study mainly adopted restrictive mediation strategies, but lacked the knowledge to undertake concrete actions in the case of implicit data collection. Implications for policymakers are discussed.
Privacy and Digital Data of Children with Disabilities: Scenes from Social Media Sharenting
Authors: Goggin Gerard , Ellis Katie
Published: November 2020

Children with disabilities have been an overlooked group in the debates on privacy and data management, and the emergence of discourses on responsibilization. In this article, we offer a preliminary overview, conceptualization, and reflection on children with disabilities, their experiences and perspectives in relation to privacy and data when it comes to existing and emergent digital technology. To give a sense of the issues at play, we provide a brief case study of “sharenting” on social media platform (that is, sharing by parents of images and information about their children with disabilities). We conclude with suggestions for the research and policy agenda in this important yet neglected area.

The article presents the experience of specialists working with children who are on long-term treatment in hospitals. Due to the pandemic, children in hospitals were placed in “double” isolation. Not only have they become separated from their usual lifestyle due to their stay in the hospital, but their contacts inside the hospital in quarantine conditions have become significantly limited. Psychologists, teachers, and speech pathologists of hospital schools were forced to switch to a remote format of work. The article analyzes the features, limitations and advantages of this format of work with children in stationary conditions.
Activity Formation by Teachers of School Students’ Learning Strategies
Authors: Chernyshova N.A.
Published: November 2020

Federal state educational standards for general education define the requirements for the results of mastering a general educational program (what to teach) and subject areas (where these educational results can be formed). However, methods, learning and teaching technologies for these competencies are not proposed. Despite of the obvious need to develop the self-regulation skills of learning, there are still no elements in the educational content that develop them. The article proposes a new approach to the design of the learning process focused on increasing motivation and developing school students’ learning strategies. The approach is based on a study conducted in 10 Moscow schools among students 8-10 grades an their teachers. The data was collected through a survey and focus groups. The purpose of this study was to identify the relation between the development of learning strategies and teachers' methods aimed at the formation of these learning skills. Paradoxical results were obtained: the less attention teachers pay to the teaching of learning strategies, the more they are developed among school students. Paradoxical results have been obtained: the less attention teachers pay to the development of learning strategies, the more they develop in school students. Based on the results analysis, a model for the formation of school students’ strategies in modern educational environment.

Authors: Byla A. B.
Published: November 2020

This article is devoted to the consideration of issues related to the legal regulation of cryptocurrencies in the Russian Federation and some foreign countries. In the course of the study, the features of cryptocurrencies were highlighted, various approaches to the definition of this category were considered, some aspects of the legal regulation of digital currencies were analyzed. It has been determined that the rules of financial law regulate a whole range of public relations related to the use of cryptocurrencies and the complex regulation of this institution is necessary. The author came to the conclusion that it is necessary to use digital technologies and digital currencies in the Russian economy in the future. At the same time, this is a complex and not an instantaneous process of transition to digital currencies; a clearly thought-out strategy for the development of legislation in this area is necessary.

Authors: Kuzhali S. , Kalyani P. , Felix A. John William
Published: November 2020

Background: Dental caries is a public health problem in developing countries like India. Indian trends show increase in prevalence of dental caries over last five decades with prevalence of 50 to 60%. The present study was conducted to find out the prevalence of dental caries and to find out the associated risk factors for dental caries among 13- and 14-years school children in urban Chidambaram.Methods: This descriptive cross-sectional study was carried out for the period of 3 months from October to December 2019. 136 students from one government and private school were selected conveniently. Data were collected using a pre-tested, structured questionnaire, which were analyzed using Statistical package for social sciences (SPSS) version 23.Results: The prevalence of dental caries was found to be 58.8%. The prevalence of dental caries was found to higher among the boys (62.1%), lower socioeconomic class students (80.4%) and students studying in the government school (66.7%). There is significant association between frequency of brushing, rinsing of mouth after taking food, brushing technique, frequency changing of brush, duration of brushing and presence of dental caries. (p<0.001).Conclusions: Lack of awareness, poor oral hygienic practices are seemingly the contributing factors for the development of dental caries. Dental caries is a preventable disease which can be alleviated by creating community awareness through health education activities.

Authors: Abid Amine , El Bouhtoury Fatima Charrier , Gabsi Slimane
Published: November 2020

Lignin is a renewable material obtained in large quantities as a by-product of the olive industry. In this context, this study aims to examine lignin as macro-monomers in the synthesis of rigid polyurethane foam after chemical modification. Indeed, the lignin extracted from the olive residue is used by chemical treatment according to the organosolv process. Comparison by characterization of the single isolated lignin and the acetylated lignin according to the physicochemical analysisTGA, DSC, FTIR, C-13 NMR, 1-H NMR, and molar mass distribution (sec) shows its value as biomass capable of being transformed into polyol afterchemical modification. acetylation increases the weight and the number of molar masses by 25-50% was also determined. Acetylation has a greater effect on the short chains which are probably richer in free phenolic groups. Mass distribution analyzes reveal a relatively high molar mass in organosolv lignin moreover, polydispersity values are very high (20 >> 1). The characterization of spent olive cake reflects the interest of using this biomass as a source of renewable energy for the production of industrial polymers.

Za celostno obravnavo Gradnikov bralne pismenosti (2018, delovno gradivo ZRSŠ) smo se v izhodišču naslonili na tri ključne dokumente, in sicer na Belo knjigo o vzgoji in izobraževanju v RS (2011), na Nacionalno strategijo za razvoj bralne pismenosti za obdobje 2019–2030 (2019) in na Osem ključnih kompetenc za vseživljenjsko učenje (2018). V okviru dela pri projektu OBJEM smo v raziskavah bralno pismenost opazovali z več vidikov, med katerimi je treba izpostaviti zlasti tri: (1) z vidika oblikovanja gradnikov bralne pismenosti, (2) z vidika didaktičnih pristopov, ki prispevajo k bralni pismenosti, še zlasti pri presoji učbeniških gradiv, in (3) z vidika izbora kakovostnih bralnih gradiv za vsa področja dejavnosti v vrtcih in vse predmete v osnovnošolskem in srednješolskem izobraževanju.
9. gradnik: Kritično branje Kritično branje – razvijajoča se veščina bralne pismenosti v vrtcu, osnovni in srednji šoli
Authors: Licardo Marta , Krajnc Ivič Mira
Published: November 2020

V poglavju je predstavljeno kritično branje kot eden od gradnikov bralne pismenosti, ki smo ga predstavili za predšolsko obdobje, za 1., 2. in 3. VIO osnovne šole ter za srednjo šolo. Kritično branje razumemo kot veščino uporabe različnih strategij za odkrivanje informacij in idej v besedilu, kamor sodita vrednotenje in vzpostavljanje kritičnega odnosa do prebranega skozi kritično razmišljanje. Analiza ciljev učnih načrtov za slovenski jezik po celotni vertikali je pokazala, da se cilji, povezani s kritičnim branjem, pojavljajo v različnih sklopih, vendar je eksplicitna raba termina kritično branje zelo redka. Operativnih ciljev, ki vključujejo ta gradnik, je malo. Ugotavljamo, da bi v učnem načrtu za slovenščino v osnovni šoli bilo smiselno dati več poudarka na cilje, vezane na razvoj kritičnega branja in kritičnega razmišljanja v 1., 2. in 3. VIO, ter da bi večji poudarek na kritičnem branju moral biti razviden tudi pri standardih znanja. Poglavje je pomembno, saj omogoča pregled ciljev, povezanih s kritičnim branjem na področju slovenskega jezika za vsako posamezno vzgojno-izobraževalno obdobje.
9. gradnik: Kritično branje Dialoški preskoki književnosti, interpretacija in doživetje, kontekstualizacija ter medmedialni prehodi
Authors: Štuhec Miran
Published: November 2020

Besedilo je uvid v različne vidike književnosti, še posebej tistih plasti, ki so v neposredni povezavi s poukom književnosti. Pri tem se ne omejuje le na srednješolsko delo, marveč upošteva tudi univerzo in njene zahteve. Idejna podlaga je prepričanje, da med eno in drugo ravnijo ukvarjanja z izbranim literarnim korpusom zmeraj ni nujno velike razlike. Dostikrat namreč gre samo za drugačen obseg večperspektivnosti in stopnjo analitične izostrenosti ali temeljitejšo sintezo. Tolmačenje, kontekstualizacija literarnega diskurza, medialnost ter doživetje, kritičnost in spodbuda za vrednotenje, estetske opredelitve, poznavanje slovstvenih procesov, občutek za jezikovne in slogovne presežke, razumevanje specifičnega literarnega pomena z vidika slovenstva itn. so presečišča različnih ali celo zelo drugačnih pogledov in hkrati njihova sredotežna sila tudi, če mislimo na srednješolski pouk (slovenske) književnosti.
3. gradnik: Razumevanje koncepta bralnega gradiva
Authors: Haramija Dragica
Published: November 2020

V poglavju o 3. gradniku, razumevanju koncepta bralnega gradiva, sta predstavljeni monomodalna pismenost in njen prehod v multimodalno pismenost, slednja od bralca zahteva sestavljanje več kodov sporočanja, da bi njihov sumativni pomen razkril celotno delo. Linearno branje poteka od leve proti desni, od zgoraj navzdol, in sicer ne glede na to, ali gre za informativno ali leposlovno bralno gradivo. Izbirno branje načeloma ni linearno, temveč bralec sestavlja parcialne pomene, šele na koncu lahko sestavi celoto. Razumevanje koncepta bralnega gradiva je pomembno za vsa področja v vrtcu in za vse predmete v osnovni in srednji šoli. Predstavljena je analiza izbrane slikanice Manice K. Musil, ki je z dvema različnima izdajama (klasična, postmoderna) dober primer za razumevanje koncepta multimodalnosti. V vseh multimodalnih analizah leposlovja se kaže, da ilustracije vplivajo na razumevanje zgodbe in (vsaj delno) spreminjajo ali natančneje predstavljajo temeljne morfološke lastnosti besedil.
5. gradnik: Besedišče
Authors: Voršič Ines , Ropič Kop Marija
Published: November 2020

Človek je edino bitje, ki se sporazumeva s pomočjo besednega jezika. Da razvije to sposobnost, potrebuje bogato besedišče, saj mora najprej ustrezno poimenovati prvine predmetnega in duhovnega sveta. Za uspešno sodelovanje v komunikacijskem procesu pa mora obvladati tudi slovnična, pravopisna in pravorečna pravila ter pragmatična načela. Osnovo celovitemu razvoju sporazumevalne zmožnosti tako predstavlja obvladovanje besedišča, ki ga je treba intenzivno razvijati že v predšolskem obdobju – obseg besedišča otrok se namreč nenehno potrjuje kot temeljni napovedovalec bralne pismenosti. V zgodnjem otroštvu otrok usvaja temeljne poimenovalne in slovnične prvine besednega jezika, proces razvijanja in širjenja besedišča pa se nato skladno z didaktičnimi priporočili iz učnih načrtov poglablja do zaključka srednje šole. Prispevek predstavlja besedišče kot ključen element bralne pismenosti, ki zajema usvajanje in širjenje besedišča, razumevanje pomena besed in njihovo rabo pri sprejemanju in tvorjenju različnih besedil ter uporabo jezikovnih virov in priročnikov. Ker se jezik nenehno razvija, na področju besedišča še posebej dinamično, ga nihče nikoli ne more do popolnosti obvladovati. Zato je širjenje besednega zaklada vseživljenjska dejavnost slehernega človeka.
7. gradnik: Razumevanje besedil
Authors: Krajnc Ivič Mira
Published: November 2020

Jezikovnokomunikacijska interakcija je v večji ali manjši meri prvina večine človekovih delovanj v skupnosti ali različnih skupinah, npr. pri igri šaha, nogometa, obisku frizerskega salona, pripravi jedi, sodni obravnavi, javnem govornem nastopanju. Osnova za sodelovanje v jezikovnokomunikacijski interakciji je razumevanje besedil, tako pisanih kot govorjenih ali tako klasičnih tiskanih kot elektronskih in digitalnih. Razumevanje besedila je proces prepoznavanja prvin nejezikovnega konteksta, npr. kraja, časa nastanka besedila, udeležencev, razmerij med udeleženci, in prepoznavanja prvin jezikovnega konteksta, npr. prenosnika, besedilne vrste, teme, tvorčeve namere in drugih leksikalnih ter oblikoslovno-skladenjskih značilnosti besedila. Obe obliki prepoznavanja prvin sta posledici naslovnikovega ločevanja bistvenega od nebistvenega, da najde smisel besedilnega sporočila, saj se ta nanaša na konkretni posamezni diskurz oziroma besedilo. Razumevanje besedila je posledica prepoznavanja dela dejanskosti, na katerega se ubesediljeno nanaša, ter razmerja med znanimi in novimi informacijami v besedilu.
Symbolic Interactionism in Poland. Inspirations and Development
Authors: Konecki Krzysztof T. , Kacperczyk Anna
Published: November 2020

In the paper, we present the development of symbolic interactionism (SI) in Poland by tracing and discussing its beginnings, as well as the influence the Chicago School had on the reception of SI in Polish sociology. Furthermore, we differentiate between two trends in the development of SI in Poland. One is connected with the early theoretical elaborations of the SI orientation and translations of classical books representing this perspective; another is linked with empirical work underpinned by SI concepts and the grounded theory approach in empirical research and data analysis. Stressing the importance of translations of classical texts of SI in its reception in Poland, we emphasize the role of field research and applications of SI concepts in sociological investigations that we shortly characterize.
Mobbing from the Standpoint of Symbolic Interactionism
Authors: Chomczyński Piotr A.
Published: November 2020

Mobbing at the workplace assumes strong, intensive, and significant interactions between an offender and a target, or a group of targets, causing serious damage to work efficiency, atmosphere, motivation, and employee fluctuation. It also highly affects the victims’ mental health, which often results in excluding them from work for a long time. The objective of this paper is to examine the issue of mobbing from the perspective of symbolic interactionism (SI) that is useful in explaining social phenomena on a micro and mezzo level. Through inductive reasoning with the use of grounded theory (GT), I focus on the narratives of mobbing targets and their stories concerning maltreatment at the workplace. The study based on a qualitative approach included 72 narrative interviews carried out among harassment victims, as well as 12 in-depth interviews with professionals dealing with the matter of mobbing. Moreover, to directly follow work-related processes linked to organizational behavior, I utilized participant observation.
Freelance Workers—Experiencing a Career Outside an Organization
Authors: Miller Piotr
Published: November 2020

This article focuses on the issues of everyday work as a self-employed, professional freelancer in Poland. The appearance of this specific category of workers on the labor market is connected with certain major changes on the economic, technological, and socio-cultural levels. The career of a freelancer is sometimes considered to be an antithesis of a corporate career. The key points are: working on one’s own, functioning outside the traditional organizational structures, HR management and supervision, promotion procedures, corporate career paths, et cetera. For a freelancer, the organization is not “an employer,” but rather “a client” or “a business partner.” The manager of the organization is not “his boss” and the employees are not his “colleagues.” As we can observe, most of the typical boundaries of a career are blurred here and that is one of the reasons why it arouses curiosity as an unusual phenomenon. The article aims to present a sociological perspective regarding the career of a freelancer in Poland. A framework of symbolic interactionism and grounded theory were applied to the author’s research (conducted in 2009-14) on which the article is based. Its first part focuses on the theoretical background and the methods that were used to collect and analyze data. The second part includes some of the author’s findings and conclusions on a freelance career from the interactionist perspective, as well as a discussion about the possible agreement and discrepancies between the author’s understanding of freelance against the widely discussed concept of precarity.
An Ethnographic Analysis of Escort Services in Poland: An Interactionist Approach
Authors: Ślęzak Izabela
Published: November 2020

In the Polish literature on the subject, prostitution is analyzed from various theoretical perspectives, but, first of all, from the perspective of social pathology. This approach makes the researchers focus mainly on the social maladjustment of women providing sex services and the reasons for their violation of the normative order. In my ethnographic research conducted in escort agencies in Poland, I was willing to go beyond this narrow outlook. I have adapted an interactionist perspective to analyze the escort agencies as organizations where intense interactions between employees, as well as employees and clients, take place, the sex work process is organized, and the meanings of prostitution are negotiated. I conducted the analysis according to the procedures of the grounded theory methodology. It allowed me to see and describe such processes as: (re)defining the situation of providing sex services from vice to work, sex work as a collective action, performing sex work, secondary socialization for sex work. The adaption of an interactionist perspective opens some new directions for analysis, which could help to understand the phenomenon of women getting involved in and continuing to provide sex services for a long time.
How Non-Heteronormative Mothers Negotiate Meaning: Experiencing and Contextualizing “Invisibility”
Authors: Wojciechowska Magdalena
Published: November 2020

This article aims to shed light on how non-heteronormative mothers—whose child had been conceived via artificial insemination of one of them with the sperm of an anonymous donor— decode, experience, and make meaning of diverse (symbolic) dimensions of their social invisibility, as well as how their understandings of the category at hand have an impact on projecting and negotiating their roles as mothers (especially in case of those women who did not give birth to their children). Drawing on specific examples from the field, I analyze how—while acting within the context of anxiety exemplifying their non-existing legal status—non-heteronormative mothers construct the image of self against the backdrop of no ready-made role scripts available, as well as strive towards making oneself (socially) visible. The insights at hand are based on data collected during my six-year ethnographic study of planned non-heteronormative motherhood in Poland, where same-sex relationships are not legally recognized.
