Authors: Cavalu Simona , Pasca Paula Melania , Brocks Marcel
Published: January 2020

The present paper describe the production and characterization of novel collagen films containing propolis encapsulated in chitosan nanoparticles, for biomedical applications such as cutaneous wound healing. Structural and morphological details were investigated by ATR FTIR spectroscopy, SEM and nanoindentation measurements, revealing the collagen fibers aligned in a quasi-parallel distribution, which might be favorable for biomedical applications. Moreover, the vibrational marker bands of propolis were well preserved in the final polymeric mixture, indicating the stability of bioactive compounds upon the encapsulation procedure. The antibacterial effect depends on the nanoparticles concentration in collagen film, the effect being more evident with respect to E. coli than S. aureus. The antioxidant capacity monitored by CUPRAC assay, indicated a synergic effect of chitosan nanoparticles matrix and propolis extract, incorporated in collagen films.

Published: January 2020

Either considering chemical munitions or chemical improvised explosive devices, the armies should be able to counter their effects from two different perspectives: the agent used and the way to disperse it. While the agent to be delivered can be more or less lethal, the real factor that gives efficiency to the attack is the manner the agent is delivered. The state-of-the-art tested garment indicate that current knowledge regarding protective equipment for chemical warfare agents remains very limited. In this context, the present study aimed at the possibility of using the MWCNT-OH-based polyurea-composite material, obtained by our group in a previous study, in the field of protection against hazardous chemicals.

Published: January 2020

FDM is 3D printing technology using mainly PLA and ABS as filament materials. PP has close characteristics to PLA and, due to that, is a potential material for for deposition. Paper aims to analyse the behaviour of PP during heating cycle specific to 3D printing process. Macroscopic and microscopic analysis of the deposited strings have been performed. They revealed less stiffness of the PP deposition comparing to PLA, which is due to the lower viscosity of PP. DSC Thermal analysis has been done at it revealed a 30% higher heat flux in PP comparing to PLA and that increases its fluidity. It was recorded a difference between the elongation viscosity of the PP filament and the PP deposited by FDM process. After 5s the deposited PP proves higher values for the elongation viscosity. Dynamic shear rheology measurements the was applied on samples deformed under 210 kN at 190oC. It has been found that the PP requires lower storage energy and that means that it has a lower viscosity for the entire range of applied frequencies. In the same time, the complex viscosities prove different behavior. To improve the control of the deposition shape, it is necessary to reduce the extrusion temperature with 4-5%. That leads to economy in power consumption.

Published: January 2020

A mathematical model regarding water filtration with a nanofiltration (NF) titanium dioxide ceramic membrane is presented. The experiments aimed to use the excitation-emission matrix (EEM) spectroscopy method to highlight the existence of humic acid (HA) in water, before and after the NF process. Following the established operating conditions, experiments were performed for each quantity of AH separately, leaving the installation to work at the appropriate parameters for 15 minutes. for each quantity of AH. The analyzes for EEM fluorescence were performed using the FP-8300 spectrofluorimeter. The collected samples were analyzed with Spectra Manager II software on fluorescence intensity (au - arbitrary units), with an emission wavelength (nm) between 460 and 640 nm and with an excitation wavelength (nm) between 350 and 600 nm. Following the experiments carried out, mathematical correlations were established between the parameters that influence the filtering process and the studied parameters. It is worth mentioning that as a result of the experiments carried out, a number of 20,450 values were obtained, which were used for the elaboration of mathematical models. These models, for sets of values of the order of tens of thousands, verified both from the point of view of the real values and from the point of view of the regression coefficients (coefficients close to the value 1), demonstrate the quantity and the very good quality of the experimental data, respectively of the measured and calculated sizes. In order to validate the generated equations, they were subjected to checks, the difference being obtained between the value obtained by experimental means and the value obtained within the mathematical model. And the value of the resulting relative error, gives information on the accuracy (truth) of the mathematical model, so that it can be extended to other experiences. It turns out that this method cannot quantitatively determine the value of a parameter, but it can highlight the presence and differences between two samples.

CONCEPTS AND THE ESSENCE OF TERMINATION OF LABOR RELATIONS
Authors: Komarnitskaya M.
Published: January 2020

The article analyzes the specifics of termination of labor relations. The author's definition of thislegal category is provided. The essence and importance of termination of labor relations are outlined,where it is established that it stipulates certain legal facts termination of legal relations between theemployer and the employee, which have arisen on the basis of the employment contract and wereformalized by it, as well as the legal consequence of the emergence and action of certain legal facts whichin the legal literature are called termination. It is clear that clarifying the concept under consideration, itis necessary to determine its separate components, such as "termination" and "labor relations. ". As forthe first component, it has less legal meaning than lexical content, and only in conjunction with thesecond component forms a separate legal category. In terminology dictionaries, termination is regardedas the action of the meaning of cease and desist, and the term "cease" is considered, in particular, how tocease to do something, to cease to happen, to remain without completion, to cease to exist, to refuse tocontinue, to put an end to any -Why; to achieve the rejection of something, the completion of something,the limit of something. It is determined that the essence of termination of employment is manifested in thefact that this category: implies, due to certain legal facts, the termination of legal relations between theemployer and the employee, which arose on the basis of an employment contract and were formalized byhim; is the legal consequence of the occurrence and action of certain legal facts, which are referred to aslawbreakers in legal literature. Accordingly, the legal connection between the employer and the employee regarding the object - work disappears, and the respective rights and obligations of the parties areterminated due to the reasons stipulated by the law. Termination of employment under any circumstancesmeans the termination of all rights and obligations of the subjects of employment relations, the conditionson which those relations were built, and always means the impossibility of maintaining the existing legalrelationship due to the absence of one or all elements of such relations. Such termination can be in threeways for the disappearance of the object of employment relations, the content of such relations, or for thesubjects of those relations. We consider it expedient and correct to use the concept of “termination ofemployment” in the draft Labor Code instead of the term “termination of employment contract” used inthe current labor legislation.

It is difficult to imagine the life of each person in a state of information vacuum, so it is naturalthat information becomes the main value of today. And the main tools in the process of its disseminationare mass media, in particular electronic media. The Internet is gradually becoming a universal, allencompassing communication environment for us, connecting many people, regardless of distances andnational borders. The online audience is steadily multiplying and therefore the impact of thiscommunication channel on the society is increasing. As the audience grows, there is a steady increase inthe amount of time people spend each day in the online communication process. Social networks arerapidly outpacing the "old" comprehensible media, benefiting from feedback from the audience. Theylisten to the wishes of readers / viewers, become an authoritative information channel. All this speaks tothe urgent need for effective regulatory regulation of the activity of social networks, such as electronicmedia, by the state. Social networks have ceased to be typical tools for the transmission of information; itis a fully segregated structure that requires "working" laws, with a clear conceptual apparatus. Theyhave long been the holders of rights and responsibilities, endowed with constitutional personality, aselectronic media. The article is devoted to research of real factors of activity of modern events as specialelectronic data of mass information. Investigated the validity of advanced measures to modern massmedia.

A Proposta de atualização da Política Nacional de Educação Especial em relação à inclusão de alunos com deficiência no Ensino Superior
Authors: Da Silva Oliveira Shimite Amabriane , Rogério da Silva Nilson
Published: January 2020

Objetivou-se problematizar as discussões a respeito da atualização da Política Nacional de Educação Especial na perspectiva inclusiva, em relação à inclusão no ensino superior. Trata-se de um estudo documental da Política de Educação Especial na perspectiva inclusiva, da proposta de atualização da Política de Educação Especial iniciada no ano de 2018 e do documento elaborado, em Maio de 2018, pelo “Laboratório de Estudos e Pesquisas em Ensino e Diferença (LEPED)”. O difícil ingresso ao ensino superior, desde a colonização, império e proclamação da república revela a base em que foram desenvolvidas as universidades no Brasil. Por meio de legislações, de programas governamentais e de ações de algumas universidades foram criadas possibilidade para a promoção de ambientes inclusivos no ensino superior. Nesse cenário, estão as propostas de “atualização” da Política Nacional de Educação Especial, com a retirada da perspectiva inclusiva. A ineficiência das ações de inclusão em âmbitos da sociedade é o principal argumento para a atualização da política, sendo necessárias discussões com os diferentes meios sociais, entre eles os de ensino, para a reflexão sobre a compreensão da diferença e, principalmente, a respeito dos direitos humanos. Sendo assim, torna-se imprescindível a reflexão proposta no presente trabalho, no sentido de avaliar se tais “avanços” e “atualizações” são benéficas às pessoas com deficiência no acesso ao ensino superior.
LOCAL AND INTERREGIONAL TYPES OF BEADS FROM LATE SARMATIAN FEMALE BURIALS IN THE STEPPE OF EASTERN EUROPE
Authors: Kyslenko H. O.
Published: January 2020

The most numerous category of finds among the funeral utensils in the Late Sarmatian female burials are the beads. Despite the mass and standardization, their potential as the dependable markers of date and location is still not developed completely. So one of the promising directions is to identify the zones of geographical distribution of the types of beads, that is, the selection of local and interregional types.
The data base of the study consisted of 38 Late Sarmatian burials containing more than 7050 beads.
At the first stage, a series of types of beads were classified according to the informative degree. Thus 39 types (found only in one buried) were considered poor informative. Other 56 types are considered well informative, because they were found in two or more burials.
In the second stage, among 56 informative types,17 local markers (those found in two or more graves from one geographic region) were identified. All assemblages were dated according the dates of burials where they have been discovered.
In the third stage, the remaining 39 informative types have been identified as interregional (those found in two or more graves from the territories of two or more regions of the studied range of distribution of the Late Sarmatian culture). They were also dated according the dates of burials. Thus, the result of the study is the selection of local and interregional markers of Late Sarmatian female burials from the territory of the steppe of Eastern Europe.
NEW EPIGRAPHIC FIND OF KYIV RUS’ TIME FROM THE OUTSKIRTS OF KYIV
Authors: Zotsenko I. V. , Vasylieva M. A. , Sitchinava D. V.
Published: January 2020

This article deals with the interpretation of new epigraphic find on the amphora fragment, from settlement Feofaniya (Kyiv, Ukraine) that was found during the excavations of the Architectural-Archaeological Expedition in 2016. Amphoras — is one of the most mass categories of imported products that came to the territory of Kyiv Rus’ from Byzantium and the Black Sea during the X—XIII centuries. They provide a sufficiently clear chronological indicator, as well as provide information on trade relations, social and property stratification of society.
The fragment (14 Ч 16 cm) clearly shows the scribbled inscription «ТЄШЄ». On the basis of the analysis, it is likely that graffiti points to the name of the owner of the amphora (perhaps named Těx or Těšen), and not to its contents (it is however plausible that the latter was wine). This part of the amphora plays an important role in the study of external relations and confirms the high status of the inhabitants of this settlement.
E. R. VON STERN AND THE CREATION OF THE NORTHERN BLACK SEA SCHOOL OF CLASSIC ARCHAEOLOGY
Authors: Kuzmishchev A. H.
Published: January 2020

Ernst R. von Stern (1859—1924) was one of the prominent historians of antiquity in the late XIX — early XX century, who participated in the development of Classic archaeology of the Northern Black Sea region.
The article discusses the role of E. R. von Stern in the creation of the school of Classic archaeology, which was based on the Novorossiisk University in Odessa and the Odessa Society of History and Antiquities, in particular the museum of that society, as well as the contribution of E. R. von Stern in education of native archaeologists and historians.
R. von Stern, having considerable experience in teaching, understood the importance of educating young professional personnel. As a result, due to a long and systematic work, E. R. von Stern was able to create a scientific school of his followers.
Among the students of E. R. von Stern were those who later became well-known scholars, connecting their lives with history and archaeology. In particular, the scientific career of B. V. Farmakovskyi (1870—1928), an outstanding archaeologist, a long-term researcher of Olbia, was largely formed thanks to the pedagogical talent of E. R. von Stern.
The most known students of E. R. von Stern, except B. V. Farmakovskyi, were also M. I. Mandes (1866—1934), E. G. Kagarov (1882—1942) and M. F. Boltenko (1888—1959).

Published: January 2020

BACKGROUND: Aceh is a tropical region that is very many overgrown by various plants that have medicinal properties; one of them is M. elengi. M. elengi flower extract has the main content of triterpene and alcohol, that have antibacterial, antifungal, antioxidant and antineoplastic activity. Extraction of chemical compounds containing essential oils generally uses distillation, and get the small amounts of chemical compounds, while the maceration with n-hexane solvent, producing less active nonpolar compounds against S. aureus bacteria.
AIM: Isolating the methanol extract from M. elengi flowers and test its antibacterial and antifungal activity. Furthermore, extracts with active concentrations are made into a lotion.
METHODS: Methanol extract from M. elengi flower was characterised by gas chromatography-mass spectrometry, then tested for antibacterial and antifungal, then made into the lotion. The lotion was tested again for its antimicrobial activity, physical and organoleptic properties.
RESULTS: The most abundant chemical compounds in an extract of M. elengi based on characterisation with GC-MS is Borneol L; (Bicyclo [2.2.1] heptane-2-ol, 1,7,7-trimethyl, as much as 82%). The methanol extract of M. elengi flower can inhibit the growth of S. aureus bacteria and C. albicans fungi, and also the lotion from methanol extract can inhibit the growth of S. aureus bacteria, but the M. elengi flower extract lotion cannot inhibit the growth of C. albicans fungi. The lotion inhibits the growth of S. aureus bacteria, from a concentration of methanol extract of 8% and 16%. Lotion with 16% methanol extract has 81.33% in activity power compared with positive control. The results of physical and organoleptic properties test, with the concentration of methanol extract of M. elengi 1, 2, 8, and 16%, have pH in the range of 6.6-8 (still in a safe range, 4.5-9 according to SNI 16-4399-1997). The lotion type is m/a, the spreading capacity of the lotion is 18.8 - 39.5 cm2. The power of adhesive at skin ranges from 1 minute 27 seconds to 3 minutes 7 seconds. The viscosity of the lotion ranges from 23,670-24,400 cP, this range is in the range based on SNI 16-4399-1996 (2000-50,000 cP), so the lotion is in a good category. The preferred lotion is at a concentration of 2%, in fragrance.
CONCLUSION: Antibacterial activity of the lotion of methanol extract of M. elengi flower against S. aureus bacteria was the best at 16%, but could not inhibit the growth of C. albicans fungi. The most abundant compounds in methanol extract are Borneol L compounds; (Bicyclo [2.2.1] heptane-2-ol, 1,7,7-trimethyl. In general, the physical properties of this lotion meet the requirements of SNI16-4399-1996, SNI 16-4399-1997, and lotions which are preferred at a concentration of 2% in fragrance.

Consumer - Oriented Street Furniture Design: Effects on the Identity of Urban Landscapes
Authors: Gjuroski Milosh
Published: January 2020

This master's thesis aims to analyze the effects of street furniture on the identity of urban landscapes and to develop a corresponding consumer-centred street furniture design solution. An understanding of three key aspects is necessary for the development of consumer-oriented street furniture which positively creates or co-creates the identity of the public space. These three aspects are: i) the users’ needs, preferences and perceptions; ii) meaning of, functions of, and interaction with street furniture; and iii) influence on the image and identity of the urban area. Historical overview, current trends, principles of street furniture design, criteria, consumer behaviour and behaviour of other stakeholders are presented in the chapter analysis and research. An overview of the most important principles of development of street furniture products - ergonomics, adaptability, inclusive design, modularity, bionics, eco-design, socialization and product life cycle - is also provided. The research and analysis consist of a literature review, survey, and concept evaluation by a multidisciplinary team of experts. First, key principles for the design of street furniture were identified based on the literature review and conducted the survey.  Next, concepts were developed based on the survey and literature review findings. Last, following best practices in leading product design companies, these concepts were evaluated by a multidisciplinary group of experts in the fields of product design, architecture and urbanism, sociology, history of art, graphic design and local government. The evaluation was implemented through semi-structured interviews as part of which segmental grades and suggestions were developed for each concept. Based on the research, it can be concluded that the influence of street furniture on urban identity is twofold: through the creation of landmark and through the development of sentiment of belonging. Finally, the best-evaluated concept was developed, detailed and visually presented

La labellisation, (re)qualification ou disqualification des marges ? Le cas du safran à Taliouine (Anti-Atlas, Maroc)
Authors: Oiry Varacca Mari
Published: January 2020

L’article porte sur l’obtention de labels pour des produits agricoles cultivés dans des régions de montagne marginalisées. Au Maroc, la labellisation est présentée par les pouvoirs publics comme une nouvelle manière de requalifier des espaces laissés pour compte en faisant reconnaître leurs singularités et la qualité des produits certifiés. Pourtant, elle peut renforcer les différences entre espaces, en revaloriser certains et en disqualifier d’autres, exclure des acteurs et attiser les conflits. Est proposée ici une lecture critique de ces processus de labellisation : sont-ils vraiment à même de réduire la marginalité d’un espace et les inégalités sociales ? La réflexion se base sur la labellisation du safran de Taliouine, région du sud du Maroc longtemps délaissée par les pouvoirs publics au point qu’elle reste une terre d’émigration. L’article étudie comment, à travers le processus de labellisation, se négocient des représentations du territoire et des savoirs agricoles différents. Il analyse le point de vue des acteurs ordinaires, autrement dit des petits paysans qui s’estiment exclus du processus. Au-delà des tensions révélées et amplifiées par la labellisation, ce travail montre les arrangements que trouvent ces derniers et les résistances qu’ils mettent en œuvre pour « faire avec » la labellisation et lutter contre la marginalisation, parfois sans le label.

Authors: Boothe Kathleen A. , Lohmann Marla J.
Published: January 2020

To support the increased diversity in the college classroom, it is vital that research-based practices are used to ensure student engagement and success. Faculty must approach online instruction with a willingness to implement teaching practices that have proven to be effective in the virtual environment. One framework for supporting the needs of all learners and enhancing student motivation is Universal Design for Learning (UDL). UDL is a proactive instructional framework that is designed to make the curriculum accessible for all students through multiple means of engagement, multiple means of representation, and multiple means of action and expression. College faculty can use the UDL framework as they plan for interactions with students, design instructional modules, and create student assignments and assessments. This chapter will provide an overview of UDL in the online college classroom, a synopsis of the relevant research literature, and practical examples from the chapter authors' online courses.
Reflection and SoTL
Authors: Zizka Laura
Published: January 2020

Reflection was introduced into educational institutions to encourage students to seek beyond the descriptive and simple response toward critical, deep thinking, and effectively make better choices. It is also an integral part of the structured inquiry of one's teaching through the Scholarship of Teaching and Learning (SoTL). Based on Dewey and Schön's foundation of reflection as linked to actions undertaken in apprentices' daily tasks, this chapter attempts to dispel common misconceptions related to reflection to show that reflection can and should be encouraged by all stakeholders in educational programs regardless of the discipline, level, or type of study. A Reflection Radar has been created to identify reflective practices in teaching and learning. The chapter concludes with how reflection through SoTL can and should be implemented as a solid, formative pedagogical tool at all levels of education and contribute to the scholarship of teaching and learning for all educators.

Authors: Rodrigo Covadonga , Iniesto Francisco , García-Serrano Ana
Published: January 2020

There are some similarities in developing distance education online courses and Massive Open Online Courses (MOOCs) using the basis of eLearning instructional design. However, the task of converting an online course into a MOOC is not as simple as direct migration of eLearning materials and assessment resources into a MOOC platform. In online learning, learners should be continually influenced by information, social interaction, and learning experiences, providing them with the knowledge to come up with new ideas to develop within an engaging course. In this chapter, the process of MOOCification a distance education online course on “Design for All for an Inclusive and Accessible Society” is explained and contextualized. The re-factorization process has been based upon the quality model used for MOOCs at UNED Abierta and the instructional design based on Gagné's events of instruction. The eLearning activities were completely refactored, along with the content itself, the interaction events, and the online assessment following the Gardner's multiple intelligences product grid.

Authors: Nazir Sajid , Patel Shushma , Patel Dilip
Published: January 2020

This chapter proposes an autonomic computing security framework for protecting cloud-based supervisory control and data acquisition (SCADA) systems against cyber threats. Autonomic computing paradigm is based on intelligent computing that can autonomously take actions under given conditions. These technologies have been successfully applied to many problem domains requiring autonomous operations. One such area of national interest is SCADA systems that monitor critical infrastructures such as transportation networks, large manufacturing, business and health facilities, power generation, and distribution networks. The SCADA systems have evolved from isolated systems into a complex, highly connected systems requiring constant availability. The migration of such systems from in-house to cloud infrastructures has gradually gained prominence. The deployments over cloud infrastructures have brought new cyber security threats, challenges, and mitigation opportunities. SCADA deployment to cloud makes it imperative to adopt newer architectures and measures that can proactively and autonomously react to an impending threat.
Feature-Based Analysis of Social Networking and Collaboration in MOOC
Authors: Chauhan Jyoti , Goel Anita
Published: January 2020

The aim of this article is to get insight into the features of social networking and collaboration in a massive open online course (MOOC) platform. We performed a feature-based analysis of twelve popular MOOC platforms – seven proprietary and five open-source platforms. Our study reveals that there are: (1) Two ways to include social networking – in-course and external; and (2) Two ways to incorporate collaboration functionality – built-in tools and third-party tools. The functionality provided by third-party tools differs; so, the selection of the tool is a challenge. For a built-in tool of MOOC, there is a need to re-identify the features for including it in any other MOOC platform; (3) Different ways to integrate the same tool in platforms; and (4) Different features of the same tool supported by various platforms. The proposed feature list helps future MOOC providers and developers to include social networking and collaboration functionality by selection, in contrast to specifying them afresh; and prospective educators can compare and select platforms, accordingly.

Authors: Wang Shiya
Published: January 2020

With the continuous development of financial information technology, traditional data mining technology cannot effectively deal with large-scale user data sets, nor is it suitable to actively discover various potential rules from a large number of data and predict future trends. Time series are the specific values of statistical indicators on different time scales. Data sequences arranged in chronological order exist in our lives and scientific research. Financial time series is a special kind of time series, which has the commonness of time series, chaos, non-stationary and non-linear characteristics. Financial time series analysis judges the future trend of change through the analysis of historical time series. Through in-depth analysis of massive financial data, mining its potential valuable information, it can be used for individual or financial institutions in various financial activities, such as investment decision-making, market forecasting, risk management, customer requirement analysis provides scientific evidence.

A network that is based on a traditional telecommunications network and the Internet is known as the internet of things (IoT). The devices in such networks connect peers and form advanced collaborations. radio frequency identification (RFID) has become a hot topic in recent years with the development of the IOT. However, the traditional RFID reader systems have some drawbacks, such as: single node failure, limited effective reading distance of the reader, and slow reading speeds. The proposed system describes how to estimate the location of an object using RFID technology. This article also incorporates a peer-to-peer (P2P) system to locate individual objects in a supply chain management network, which enables scalable indexing of objects in large distributed traceable networks.
Achieving Cloud Security Using a Third Party Auditor and Preserving Privacy for Shared Data Over a Public Cloud
Authors: Gutte Vitthal Sadashiv , Devulapalli Sita
Published: January 2020

Correctness of data and efficient mechanisms for data security, while transferring the file to and from Cloud, are of paramount importance in today's cloud-centric processing. A mechanism for correctness and efficient transfer of data is proposed in this article. While processing users request data, a set of attributes are defined and checked. States with attributes at different levels are defined to prevent unauthorized access. Security is provided while storing the data using a chunk generation algorithm and verification of chunks using lightweight Third-Party Auditor (TPA). TPA uses digital signatures to verify user's data that are generated by RSA with MD5 algorithms. The metadata file of generated chunks is encrypted using a modified AES algorithm. The proposed method prevents unauthorized users from accessing the data in the cloud environment, in addition to maintaining data integrity. Results of the proposed cloud security model implementation are discussed.
