Published: December 2021

Information comes from a collection of data obtained from various sources that have been processed. An information can help in decision making, so it is considered to have a high effectiveness value for the recipient of the information. Information exchange that utilizes public media internet services is widely used, so the validity of information must be done security from unauthorized attacks. One of them uses cryptography. AES is a method used by the National Institute of Standards and Technology (NIST) as a standard for the United States Federal encryption algorithm. Creativity in cryptographic modification can increase the strength of an attack. This study uses AES 128, 192, and 256 bit CBC mode algorithms by conducting trials at the level of encryption, decryption and the appearance of character frequencies. Encryption test results obtained an average speed of 128 bit blocks, namely 14.2 ms, 256 bits 13.2 ms and 192 bits 11.5 ms. While the decryption test results obtained an average speed of 128 bit blocks, namely 13.2 ms, 192 bits 14 ms and 256 bits 16.5 ms. The pattern of occurrence of the average frequency generated by 9%, by accepting symbols and numbers using this algorithm has little to solve by reading the characters display. The validation test produces a value of 100% where the functionality testing shows the expected results.Keyword: Security Information, AES, CBC, AES Mode CBC Abstrak Informasi berasal dari sekumpulan data yang didapatkan dari berbagai sumber yang telah diolah.

Published: December 2021

This research will discuss the analysis of the design and manufacture of website-based e-certificate applications using the Object Oriented Programming (OOP) method. The main problems that underlie this research are the waste in the use of paper and the cost of printing certificates, as well as the difficulty of distributing certificates to participants for every activity held in an agency. In addition, another problem is the number of fake certificates from activities that have been held and the difficulty of checking the authenticity of these certificates. Therefore, we need an application that can facilitate the making of certificates without having to be printed conventionally, assist in distributing certificates from activities that have been held to activity participants, as well as in checking the authenticity of certificates. For making applications using the OOP method with tools Unified Modeling Language (UML) as a tool in designing applications. The results achieved from this research are a website-based e-certificate application that will be used to print certificates digitally (paperless), distribute e-certificates from every activity organized by an agency, and check the authenticity of certificates using QRCode technology.
Potres u Đakovštini 1964. godine – stradanje i tijek obnove katedrale svetoga Petra u Đakovu
Authors: Josipović Batorek Slađana
Published: December 2021

U radu se na temelju dostupnoga arhivskoga gradiva i onodobnoga tiska govori o posljedicama potresa koji je 1964. pogodio Slavoniju i prouzročio veliku materijalnu štetu. U uvodnom dijelu daje se kratki prikaz štete nastale na području kotara Osijek, tj. općine Đakovo, te osnovni podaci o štetama na vjerskim objektima. Središnji dio rada posvećen je analizi posljedica potresa i procesu obnove katedrale svetoga Petra u Đakovu, koja je tek bila započela s popravljanjem oštećenja nastalih još u Drugom svjetskom ratu. Glavnu riječ tijekom obnove imao je Stolni kaptol i u tu svrhu osnovan Odbor za obnovu katedrale, ali i tadašnji biskup Stjepan Bäuerlein, koji je brojnim predstavkama upućenim državnim vlastima nastojao ishoditi novčanu pomoć za potrebe obnove. U tom je smislu cijeli proces obnove katedrale zanimljivo pratiti i u kontekstu odnosa između Katoličke crkve u Jugoslaviji i komunističkih vlasti, koji su šezdesetih godina bili u znaku popuštanja napetosti.
Koncepcija općenarodne obrane i društvene samozaštite – militarizam samoupravnoga socijalizma
Authors: Marijan Davor
Published: December 2021

Koncepcija općenarodne obrane i društvene samozaštite, kako se od sredine 1970-ih zvao jugoslavenski obrambeno-zaštitni sustav, počela se provoditi nakon invazije zemalja Varšavskoga ugovora na Čehoslovačku u kolovozu 1968. Jugoslavenski komunisti smatrali su da se takvoj, iznenadnoj i uspješnoj agresiji mogu učinkovito suprotstaviti samo organiziranim angažmanom svih raspoloživih potencijala društva na temelju svojega revolucionarnog iskustva i promišljanja klasika marksizma o naoružanome narodu. Tako je počela nastajati obrambena koncepcija koja je osjetno opteretila društvo, povećala ionako velike financijske izdatke za vojsku i potaknula militarizaciju društva. Premda
je istovremeno s obrambenom funkcijom problematizirana i funkcija sigurnosti društva pod imenom društvena samozaštita, pravi poticaj za njezino teorijsko i praktično uobličavanje dao je upad naoružane skupine
Feniks u Jugoslaviju u ljeto 1972. No do koliko-toliko učinkovite fuzije tih dvaju zaštitnih kompleksa doći će tek 1979. osnivanjem komiteta za općenarodnu obranu i društvenu samozaštitu, koji su u obrambeno-zaštitnom sustavu trebali osigurati rukovodeću ulogu Saveza komunista Jugoslavije.

Published: December 2021

Rate coefficients for electron-impact dissociation of O3 + to the O+ and O2 + fragments are calculated for the new, recommended cross section data set and for various collisional conditions. Two sets of the cross section data, measured recently by different experimental groups, are used. These cross sections differ significantly with each other, but are renormalized and optimized to the coherent data base. Rate coefficients for the ozone cation fragmentation are determined using the Maxwellian and the non-thermal electron energy distribution functions (EEDF). In the case of Maxwellian distribution, mean electron energies cover the range from zero up to 2 keV. Non-thermal electron energy distribution functions are adopted from the recent electron observations by the 3-D plasma and energetic particles experiment on the WIND spacecraft. The non-thermal rates are evaluated for the mean electron energies from 4 to 80 eV. The role of the possible contribution of electron-impact dissociation of O3 + to the ozone layer depletion has been emphasized.

Published: December 2021

The aim of this in vitro study was to quantitatively evaluate the internal gap of resin composites of high-and low-viscosity used in single- and incremental-fill techniques in Class I cavities exposed to thermal cycling (TC) using optical coherence tomography (OCT). Cavities of 4-mm depth and 3-mm diameter were prepared in 36 third molars randomly distributed into four groups, according to viscosity of restorative resin-based composite (high or low viscosity, all from 3M Oral Care) and technique application (bulk or incremental fill) used (n=9): RC, high-viscosity, incremental-fill, resin-based composite (Filtek Z350 XT Universal Restorative); BF, high-viscosity, bulk-fill, resin-based composite (Filtek One Bulk Fill); LRC, lowviscosity, incremental-fill, resin-based composite (Filtek Z350 XT Flowable Universal Restorative); and LBF, low-viscosity, bulk-fill, resin-based composite (Filtek Flowable Restorative). Single Bond Universal Adhesive system (3M Oral Care) was used in all the experimental groups. The incremental-fill technique was used for RC and LRC groups (2-mm increments), and a single-layer technique was used for BF and LBF groups, as recommended by the manufacturer. The internal adaptation of the resin at all dentin walls was evaluated before and after TC (5000 cycles between 5°C and 55°C) using OCT images. Five images of each restored tooth were obtained. Images were analyzed using ImageJ software that measured the entire length of the gaps at the dentin–restoration interface. The length of gaps (μm) was analyzed using two-way repeated measures ANOVA and the Tukey tests (α=0.05). There was a significant interaction between material types and TC (p=0.006), and a significant difference among all material types (p<0.0001), before and after TC (p<0.0001). Increased internal gaps at the dentin–restoration interface were noticed after TC for all groups. RC presented the lowest value of internal gap before and after TC, while LBF showed the highest values of internal gap after TC. In conclusion, TC negatively affected the integrity of internal gap, whereas high-viscosity, incremental-fill, resin-based composite presented better performance in terms of internal adaptation than low-viscosity, bulk-fill materials in Class I cavities.
A scientometric analysis on pre- and post-copulatory traits in Odonata
Authors: Pestana Gabrielle Cristina , Mateus-Barros Erick , Brasil Leandro Schlemmer , Guillermo-Ferreira Rhainer
Published: December 2021

In the last decades, studies on sexual selection in odonates have shown a relationship between mating success and costly sexual ornaments, mainly male characters. Here, we conducted a scientometric analysis to assess the state of art of studies on sexual selection in odonates, especially on the role of male ornamentation (pre-copulatory traits) and sperm competition (post-copulatory traits). We found 51 papers focused on sexual ornamentation and 34 on sperm competition. Only one study simultaneously addressed both pre- and post-copulatory traits, nevertheless without an integrative approach. Results show that calopterygids are extensively studied regarding pre-copulatory traits (i.e., male wing pigmentation), while libellulids are mostly studied in post- copulatory traits (e.g., sperm competition) focused research. These preferences seem to be related to characteristics like presence of ornamentation and territoriality, large body size, variation and complexity of sperm removal structures, respectively. For the post-copulatory traits, sperm removal is frequently addressed, but few other strategies, like the investment in sperm quality and quantity, are investigated. Finally, we demonstrate that it is necessary to conduct studies focused on addressing the relationship between pre- and post- mating sexual traits.

Authors: Blažková Gabriela
Published: December 2021

This study is an overview of the professional interest in archaeology of the modern age in the Czech Republic. Increased interest in the archaeology of the Modern period came after the year 2000. The number of published Early Modern pottery assemblages has increased significantly over the past decade. Recent years have seen a change in the publication strategy of Modern period assemblages. As such, the large Modern period find inventory is forcing archaeology to make a critical selection of assemblages which will subsequently be the subject of detailed processing and evaluation. The most important selection criteria include the complexity of the find situation, the possibility of placing it into the social context or the actual expansion of knowledge of period material culture.

HISTORICAL FORTIFICATIONS IN THE ARCHITECTURAL AND URBAN PLANNING STRUCTURE OF LVIV (ON MARGINES DOCUMENTATION "HISTORICAL AND ARCHITECTURAL REFERENCE PLAN OF LVIV")
Authors:   Lviv Polytechnic National University, Department of Architecture and Conservation, M Bevz
Published: December 2021

Ancient city fortifications are one of the specific types of defensive architecture. Along with the buildings of castles, blocks of urban residential development, monastery complexes and field defensive structures, they formed a special type of architectural and urban planning objects. During their construction, the skills of both an architect, builder, and military engineer were often combined. Not so many objects of urban defense architecture have come down to our time. Therefore, every fragment of the city's defensive walls and earthen fortifications preserved today, as a rule, is a valuable document of its era and needs careful protection and preservation. Urban fortifications (as opposed to fortifications of castles or fortresses) were the objects of priority liquidation in the process of urban development. There are very few of them preserved in Ukraine, so their preservation and study is a matter of extreme importance. Lviv is a unique city on the map of Ukraine in terms of the development of urban fortifications. The article analyzes the reflection of objects and monuments of defense construction in the scientific and design documentation "Historical and Architectural Reference Plan of the City of Lviv". Data on the stages of development of Lviv fortifications are highlighted. Special attention is paid to the remains of fortifications that have been preserved in the archaeological form. Their identification, conservation and identification is important task for modern urban development projects. The paper makes hypotheses about some hitherto unidentified elements of fortifications of the XVII-XVIII centuries. Special emphasis is placed on the need for a special scientific study on the detailed reconstruction of all stages of the development of defense belts around the city center and suburbs of Lviv
SCULPTURE WORKSHOP: PROFESSIONAL REQUIREMENTS FOR CREATING A LEARNING ENVIRONMENT
Authors:   Lviv Polytechnic National University, Yu Dyba , V Gogol ,   Lviv Polytechnic National University
Published: December 2021

One of the necessary and mandatory conditions for high-quality professional art education is training in an environment that encourages creative work and provides the necessary level of comfort, ergonomic, technological, sanitary and technical requirements and proper organization of labour protection. Compared to other artistic professions, the working environment of a sculptor is more complex. It must be equipped with the necessary technical equipment (mostly quite large) and manual and mechanical tools, take into account functional requirements and complex technological processes, as well as provide the necessary and diverse indicators of lighting level, temperature, humidity, noise, etc. All these requirements also apply to sculpture academic workshops, where students learn the basics of the profession. Subsequently, graduates of sculpture departments use the acquired skills in their creative activities. Stating a certain degradation of the requirements for the profession of the sculptor, the authors of the publication express worries about the obvious underestimation of requirements for the workplace of a professional sculptor, which can be observed in numerous examples, and remind the reader of these basic requirements

Authors:   Lviv Polytechnic National University, Department of Architectural Environment Design, B Tyrchyn
Published: December 2021

The article discloses the peculiarities of the nature and residential environment in the first garden cities in Galicia: “Salwator” in Krakow and “Novyi Svit” in Lviv. The topicality of the issue is predetermined by the need for supplementing and developing available scientific researches related to the study of the garden city concept as well as for analyzing profoundly and comparing the architectural and townplanning structures of the garden cities in Galicia at the early stages of their development. Both general scientific methods (historical, comparative, structural analysis), and special field observations have been used. This comprehensive approach has enabled us to point out the special features (planning, functional) of the garden cities as exemplified by Lviv and Krakow. It has been proven that the development of the architecture and town planning of the above cities in the early ХХth century corresponds to the general European trends, while the concept of garden cities was implemented in a fragmented way, that is in the form of gardens-on-the-outskirts.

Authors: Kravarusić Vesna
Published: December 2021

The indisputable importance of early learning as well as the accepted documents of international organizations dealing with education have an impact on educational policy in the Republic of Serbia. Systemic solutions support the professional progress of educators/preschool teachers. Clearly limited and publicly recognizable areas of practice, accumulated fund of knowledge acquired through education, experience, which is expanded and deepened by continuous improvement and exchange with the environment; independent and/or cooperative decisions on timely and correct actions; meeting internal and external standards (self / control); ethics in personal and professional life are characterized by professional/competent actions of educators. Factors that modulate the level of competence of educators are the status of society, the immediate social context, the quality of the study program, professional environment, continuous professional development, pedagogical practice, personal characteristics of educators, job satisfaction and private life. The paper critically examines the key elements of the structure of factors in the Republic of Serbia in order to put light on weak points and their improvement. The research of a set of macrosystemic and subsystemic factors points out to the necessity of restructuring, improvement of the quality of selection, basic education of educators, interventions in the offer of trainings in accordance with the real needs of educators. Ensuring an effective, respectful climate in the preschool institution is necessary for microsystem changes. Pedagogical implications are contained in the creation of conditions for the development of participatory relations, critical observation, but also the emancipation and independence of professionally accomplished educators.

Published: December 2021

One of the most common methods of strengthening concrete structures is the use of composite fibers such as FRP. These fibers have found a special place in structural retrofitting methods due to a number of specific ability including lightness and ease of performance. Reinforced concrete structures have long been considered by design engineers for the possibility of retrofitting high strength composite steel structures. In this study, twenty-two steel beam models were modeled by ANSYS software. Variable parameters studied in the modeled steel beams can be referred to the number, orientation and thickness of composite layers.

The article presents the results of the research aimed at identifying the influence of the aggregate on the plasticity of concrete mixtures used in formless molding. The authors provide a brief overview of the existing concepts regarding the effect of the aggregate on the rheology of mixtures and their plastic properties. There is offered a description of the materials and techniques used, as well as the experiment and analysis of the results obtained. There have been experimentally established two mechanisms of the influence of the aggregate on the plasticity of the concrete mixture. Due to the sorption of water from the cement paste, the aggregate, at any of its volumetric concentrations, reduces its ultimate tensibility and, as a consequence, the plasticity of the entire mixture. When the volume fraction of 41 % is exceeded, the aggregate also depletes the sufficiently plastic component of the mixture - cement paste - thereby reducing the ultimate tensibility of the mixture, which enhances the effect of drying the paste.

Increase of the requirements for the safety of hazardous production facilities stimulates the development and improvement of the methodological approaches to accidents consequences assessment on the main gas and other pipelines. Existing models for determining heat fluxes from radiating flame surfaces are focused on assessing damage under standard conditions when the epicenter of the accident is at the same altitude level with potential recipients and there are no barriers between them. In practice, special conditions are often implemented, in particular: fires on the pipelines located in the mountainous areas, safe passage of aircraft near the burning site, protection of objects from thermal radiation by installing impenetrable screens. Approaches are proposed related to assessing heat fluxes at the receiving sites located at different altitude levels with the fire source, as well as during accidents with ignition on the gas pipelines in the presence of screens protecting against thermal radiation. A parameter is introduced that describes the effect of the multilevel location of the source and the recipient on radiation — the coefficient of change in the thermal radiation flux from the side surface of a column-type fire in the absence of a wind, depending on the location height and distance in relation to the ground source of combustion of the site receiving the radiation. An expression is given for determining safe height of the flight of aircraft over a column-type fire in the range of flame heights from 50 to 850 m. Isolines of the fields of heat fluxes from the flame of a high-speed flat jet are calculated when the radiation is screened by a wall located at a normalized distance. The results obtained make it possible to predict the consequences of accidents on the main gas pipelines with gas ignition considering the relief, to assess the boundaries of safe corridors for flights of the aircraft near gas pipelines, and to efficiently develop means of protecting objects surrounding the main pipelines from thermal radiation from a flat torch.

Published: December 2021

Despite the industrial revolutions, optimization of production processes, the use of robotics and other advances of science and technology, the share of machine-tool equipment in the execution of the plan at industrial enterprises is large. Human-machine interaction is also invariable. In this regard, the injury rate of machine operators from year to year remains above average. To manage the employee occupational risks, it is required to carefully analyze the source of the risk — the machine-tool equipment used. To manage the professional risks of a machine operator, it is required to assess the following parameters of the machine-tool complex: traumatic factors in accordance with the current legal requirements, and the data obtained as a result of the equipment practical application; completeness and content of the technical documentation for the machine-tool equipment; equipment life cycle stage, equipment operation period; fulfillment of the scheduled preventive maintenance schedule; the number and nature of emergency equipment failures; ergonomic indicators of the machine. The analysis carried out according to the specified parameters can be presented visually in the form of a diagram reflecting the condition of machine equipment on six elements and on three levels using generally accepted signal colors: green - corresponds, yellow — partially corresponds, red — does not correspond. Thus, the results of the conducted analysis are visualized on a color chart, and mathematically evaluated as a percentage. Comprehensive assessment of the state of machine-tool equipment makes it possible to more efficiently determine the risks for those working on the machine-tool equipment, as well as develop measures for the modernization or replacement of the machine-tool park.
On the Methodology for Assessing the State of Industrial and Fire Safety at the Enterprises of Oil and Gas Complex of Russia

Published: December 2021

The statistics of fires and accidents at the enterprises of oil and gas complex of Russia is presented. The choice of the method for assessing the state of industrial and fire safety is substantiated. It allows to transform the input information presented in the form of a characteristic description of the assessed event into an output dana that has a weighted numerical value. It is shown that the stable functioning of industrial enterprises depends on the safety margin of industrial and fire safety systems. Their maintenance at a certain level requires the allocation of resources (material, human, temporary, etc.), which are limited and insufficient to meet all the requests from the service managers. It is required to scientifically substantiate the targeted provision of activities that have a high index of risk. The purpose of the article is to obtain the result of the assessment of these measures in the form of a weighted risk indicator. This will allow to normalize each event included in the checklists (control sheets) of the enterprise for both industrial and fire safety. A pairwise comparison of the factors and alternatives using the selected method of hierarchy analysis makes it possible to identify the indicators of local and global priorities for each element under study. The weighting coefficients obtained in the form of local priorities relate to the event being tested. Global priorities are directly related to the services and structural units that ensure the sustainable functioning of the industrial and fire safety systems. Use of the methodology for assessing the state of industrial and fire safety at the objects of oil and gas complex of Russia will allow to transfer the management system of these enterprises to a new qualitative level.

Influence of the factors such as age and professional length of service of the drivers on the frequency of industrial injuries is considered. For conducting analysis, the statistical data was used related to the incidents that occurred on the land transport in one of the Russian oil and gas companies in the period of 2006–2019. Despite the fact that the transportation by land transport is not the main area of the company activity, this group of incidents takes the second place. Therefore, study of the factors on which the number of incidents on the land transport may hypothetically depend is relevant. The main tool of the analysis in the work is Pareto diagrams, which are used to determine the age group and that length of professional service of the drivers, in which the greatest number of incidents occurred on the land transport. Further, using the correlation method the dependence was determined, and the qualitative assessment of the obtained relationship tightness was carried out. Of the two hypotheses put forward in the work about the influence of the age and length of service of the drivers on the number of incidents on the land transport, one was confirmed — with an increase in the length of service of the drivers, there is a tendency of reducing the risk of an incident occurrence. The results of the conducted analysis allow to conclude that in addition to the basic statistical data on incidents, it is required to study and consider other factors that can affect on the number of incidents on the land transport, one of which is the level of safety culture of the drivers.

Published: December 2021

We evaluated the effectiveness of an application of middle-dose monophasic oral contraceptives (aethinyloestradiolum, desogestrel) for the maintenance of hormonal homeostasis and treatment of the most common complications that occur in the first three months after abortion. The use of oral contraceptives on 7-9th day caused the termination of blood discharge, signs of mastopathia and normalization of menstrual cycle. Thus, administration of drugs maintaining hormonal homeostasis is recommended as an effective method of correction of complications of pregnancy termination in early terms.

After comprehensive clinical, laboratory and instrumental investigations of 51 children, who suffer from bronchial asthma, it was determined that in patients with atopic asthma slow acetylation status increased the possibility to detect a severe bronchial lability (bronchial lability index more than 30 %) by 4,4 times compared to the patients with fast acetylation status. For atopic phenotype of disease availability of correlations between bronchial lability indices and bronchialobstruction severity was established (r=0,7, p<0,005) as well as duration of illness (r=0,8, p<0,001), frequency of rehospitalization of patients (r=0,6, p<0,05). In patients with nonatopic form of the disease relationships between bronchiallability indices and clinical features of disease depending on acetylation status haven’t been reported.
FasL-mediated apoptosis in chronic carrageenan-induced gastroenterocolitis
Authors: A. S. Tkachenko
Published: December 2021

The levels of sFasL and caspase-3 activity were studied in blood serum of rats with chronic gastroenterocolitis developed after intake of carrageenan during 2 and 4 weeks. It was established that the disease was accompanied by increased activity of caspase-3, more considerable in case of more prolonged carrageenan consumption suggesting activation of apoptosis in chronic intestinal carrageenan-induced inflammation. The elevated level of sFASL was observed, which was higher after 2 weeks of carrageenan intake. It indicated the predominance of FasL-mediated apoptosis of enterocytes in the early stages and the significant role of other mechanisms of apoptosis in the later stages of chronic carrageenan-induced intestinal inflammation.

Optical spectroscopy in medical diagnostics
Authors: O. I. Olar  , O. Yu. Mykytiuk  , K. I. Yakovets
Published: December 2021

In this review we consider the possibility of optical spectroscopy techniques, namely: optical tomography, optical coherent tomography, polarization-sensitive optical coherent tomography, Raman spectroscopy and photoacoustic tomography. The physical basis of optical diagnostic techniques is the interaction of light with matter, allowing of obtaining structural, biochemical, morphological and physiological information as a result of absorption, scattering, reflection of electromagnetic radiation in the optical range. The advantages of these methods, such as non-invasiveness, absence of side effects, contactlessness, high sensitivity, and high resolution are keys to their success in medical diagnostics.

В Тюменской области произрастает 4 эндемичных растения и 13 реликтовых. Одно из них (Бруннера сибирская) является одновременно и эндемиком и реликтом. Важнейшей частью работы является создание серии открыток об этих растениях. Этот труд стал основным результатом. Коллекция открыток «Эндемичные и реликтовые растения Тюменской области» насчитывает 13 растений, большая часть которых – реликты, то есть растения, сохранившиеся на нашей территории с доледниковых времен. Открытки выполнены в технике высокой печати – линогравюра, что позволило сделать процесс изготовления открыток технологичным (приблизить его к производственному). С каждой доски отпечатано 10 экземпляров открытки, при этом сохранилась возможность продолжения печати.

There are 4 endemic plants and 13 relict plants growing in the Tyumen region. One of them (Brunner Siberian) is both endemic and relict. The most important part of the work is the creation of a series of postcards about these plants. This work was the main result. The collection of postcards "Endemic and relict plants of the Tyumen region" has 13 plants, most of which are relics, that is, plants that have been preserved on our territory since pre-glacial times. The postcards are made in the technique of high printing - linocut, which made it possible to make the process of making postcards technologically (bring it closer to production). 10 copies of the postcard were printed from each board, while the possibility of continuing printing was preserved.

Rannsóknir sýna að gæði þjónustu og ímynd stuðla að betri frammistöðu í starfsemi fyrirtækja og stofnana. Markmið þessarar rannsóknar er að þróa líkan, sem fengið hefur vinnuheitið QIP-líkanið, sem leggur mat á að hve miklu leyti þessir þættir geta útskýrt breytileika í frammistöðu og hvort einn þáttur geti talist mikilvægari en annar. Enn fremur er lagt mat á hvort mismunur er eftir því hvar svarendur eru í viðskiptum í bankaþjónustu, sem alla jafna er talin fremur einsleit. Rannsóknin byggir á viðhorfskönnun meðal viðskiptavina þriggja stærstu viðskiptabankanna á Íslandi vorið 2021 en þessir bankar hafa yfir 95% markaðshlutdeild á viðskiptabankamarkaði. Alls svöruðu 719 einstaklingar könnuninni en eftir að búið var að eyða út ófullnægjandi eða gölluðum svörum var fjöldi gildra svara 480. Spurningalistinn sem notaður var byggir á rannsóknarverkefni sem hófst árið 2004 þar sem lagt er mat á þróun ímyndar banka á Íslandi auk spurninga sem lögðu mat á þjónustugæði og meðmæli. Svör voru vigtuð út frá kyni og aldri og lýsandi þáttagreining sýndi fram á fjóra þætti: gæði 1, gæði 2, ímynd, og frammistaða en allir þættirnir sýndu viðunandi hleðslu (α > 0,7). Niðurstöður sýndu að líkanið útskýrði 65% af breytileika í frammistöðu (R2 = 0,65). Af þeim þáttum sem notaðir voru til að útskýra breytileikann kom í ljós að gæði 1 hafði mest vægi (β = 0,44) en sá þáttur einn og sér útskýrði 9% af breytileikanum í frammistöðu (P2 = 0,09). Sá þáttur sem hafði næst mest vægi var ímynd (β = 0,35) sem útskýrði 7% af breytileikanum í frammistöðu (P2 = 0,07). Sá þáttur sem útskýrði minnst af breytileikanum var gæði 2 (β = 0,13) en hann einn og sér útskýrði aðeins 1,1% af breytileikanum í árangri (P2 = 0,011). Í ljós kom að nokkur munur var eftir því hvar svarendur voru í viðskiptum. Þannig hafði gæði 1 afgerandi mest vægi meðal viðskiptavina Banka A (β = 0,56) á meðan að þátturinn ímynd hafði mest vægi á meðal viðskiptavina Banka C (β = 0,48). Vægi þátta var jafnara meðal viðskiptavina Banka B.
Cestopisy ve službách nacionalismu: Význam díla Václava Vratislava z Mitrovic v procesu utváření české národní identity
Authors:   University of West Bohemia, Ovský Přemysl
Published: December 2021

The formation of nationalism, varying between theories of primordialism and modernism, is a living topic among the scholarly and general public. This work is based on the assumption of the modernist theory of the formation of nationalism. The aim is to evaluate the significance of the travelogue of Václav Vratislav of Mitrovice in the process of the Czech national identity formation by analysing individual editions of Vratislav´s travelogue. As a member of diplomatic mission, Václav Vratislav came to Turkish Constantinople by the end of the 16th century. After his return home, he wrote down the experiences from the journey, but the work had not been published until 1777. Since then, the book has been published a total of eleven times. The modern language in which his masterpiece was written played a crucial role in its popularity. During the formation of Czech nationalism, the style of this book helped to codify the modern Czech language. Furthermore, the first edition of the book did not reproduce Vratislav´s original text, but it was altered by the editor just for national-revivalist purposes. Thus, it is an artificially modified national symbol supporting the newly formed Czech nationalism. In the additional editions, the book of travels became an ethnic symbol, which played an important role in forming the Czech nation. It has been perceived as the founding stone of the Czech national feeling, which has been strengthened by repeated re-editions over the next two centuries until the present day.

Published: December 2021

This paper is concerned with making 3D scans of semitransparent ambers with and without inclusions. The paper presents results of using a variety of devices applied for this purpose. Equipment used in the experiments includes a 3D laser scanner, a structured light scanner, a stereo camera, a camera array and a tomograph. The main object used in the experiment was an amber with a fossil of a lizard. The paper shows possibilities of acquiring the 3D structure of fossils embedded in semitransparent material which interfere with the measurement performed by 3D scanning equipment. Moreover, the paper shows the application of results of 3D scanning as the 3D scan of a lizard was reconstructed in a virtual reality cave making it possible to visualize in detail its shape and texture
