Published: December 2020

With the growing level of competition in the global and national tourism markets, the issues of assessing the attractiveness and potential of the tourist and recreational sphere of the regions become especially relevant. There are several approaches to solving these problems, each of which has its advantages and disadvantages, a specific information base and options for application in practice. The purpose of the study is to develop methodological frameworks for assessing the potential of the tourist and recreational sphere of the regions in terms of its attractiveness, which will determine the attractiveness of this area for Ukrainian and foreign investors. The article considers the tools for studying the tourist and recreational potential of the regions, which, in contrast to the existing ones, includes an assessment of the attractiveness of the tourist and recreational sphere of the regions; analysis of the contribution of the tourist and recreational sphere to the economy of the regions; identification of the importance of factors influencing the formation and building of the potential of the tourist and recreational sphere of the regions. The methodological approaches to the integrated assessment of the attractiveness of the tourist and recreational sphere of the regions proposed by the author, in contrast to the existing ones, are based on the identification of the resource structure of the attractiveness of the tourist and recreational sphere in terms of four sub-indices (index of cultural attractiveness, index of attractiveness of recreational resources, index of attractiveness of tourist infrastructure and index of investment attractiveness of tourist and recreational sphere) for the development of sound mechanisms of regional marketing in the Ukrainian and foreign markets of the tourist product. The developed methodological approach is based on the use of the parametric method, which due to the ranking of standardized values of the main indicators of the tourist and recreational sphere of the regions, allows determining their place in the national rating of attractiveness. The practical use of the developed approaches will allow ensuring the efficient use of available tourist and recreational resources, increase the investment attractiveness of the territory for Ukrainian and foreign investors identify problems of potential use and create conditions for overcoming them, which will increase the competitiveness of the proposed tourism products, as well as on the basis of problem-based approach to justify the tools for implementing national and regional targeted programs for tourism and recreation. Key words: region, potential, tourist-recreational sphere, attractiveness, methodical approach, evaluation.

The main purpose of the industrial enterprise is to ensure its sustainable development. This can be achieved by constantly seeking and implementing measures to improve the economic efficiency of management. Cost is one of the indicators that affects the efficiency of economic activity of the enterprise and its structural units. It concentrates the main indicators of economic and production activities, namely: the efficiency of financial, material, labor and other resources, and hence the quality of employees and the enterprise as a whole, their advantages, achievements and losses and shortcomings. Cost directly affects the profitability, profit and financial result of economic activity. The main aim of the article is the analysis and generalization of approaches to interpretations of the concept of cost, the role and importance of the cost indicator in production management, its place in the economic mechanism of management. Theoretical general scientific research methods (analysis, abstraction, generalization, classification, etc.) have been used. The article emphasizes that the cost should be understood as the value of the cost of resources used in the production and sale of products. The study showed that the cost, as a generalizing economic indicator, reflects all aspects of the enterprise: the degree of technological equipment of production and development of technological processes, the level of organization of production and labor, the degree of capacity utilization, economy of material and labor resources and other conditions and factors that characterize production and economic activities. The practical significance of the obtained results is to clarify the meaning of the concept of cost as a generalizing economic indicator. The scientific novelty of the study is to determine the feasibility of taking into account in the formation of the cost indicator not only the cost of resources used in the process of achieving certain goals, but also the costs associated with the risky, innovative nature of entrepreneurship. Further research will be aimed at finding new methods and factors to reduce the cost of production of enterprises in Ukraine. Keywords: cost, cost of production, cost of production, cost accounting

Trends in tourism development of the XXI century suggest that one of the promising areas related to the acquaintance with the production, cooking technology and tasting of national dishes and drinks is gastronomic tourism. The concept of forming a tourist product in the form of a gastronomic or culinary tour combines economic, social and cultural values of the territory, covers the climate, traditional agriculture and crafts, art, national customs, traditions and life. That is, gastronomic tourism fully contributes to the development of the tourism sector and is a means of activating the tourist destination. The article deals with the directions of gastronomic tourism development as a means of activating tourist destinations and supporting national producers through the integration of gastronomic tourism into local event resources. The relevance of these issues is determined by the lack of a holistic understanding of the concept of gastronomic tourism, the imperfection of existing recommendations and conclusions on its formation. The purpose of the article is to study the features of gastronomic tourism as a means of enhancing the development of tourism. The article determines that the basis of gastronomic tourism is the features of regional cuisine and culinary traditions of the tourist destination. The scientific novelty of the research results is the deepening of theoretical approaches to the study of gastronomic tourism - a new direction of cultural and cognitive tourism, which is relevant to combine with eco-tourism, tourism in protected areas, rural green tourism. After all, the latter have a large stock of cultural, culinary, authentic traditions that should be revived and developed. Gastronomic tours will form a new vision of tourism in the context of destination development. The article notes that from the point of view of organizing tourist activities, gastronomic tourism includes not only acquaintance with local cuisines of the region, original technologies of local food organization, culinary processes and food traditions, acquaintance with local products, but also the opportunity for tourists to participate in cooking. national dishes, visiting culinary festivals, various types of tastings and competitions.

The Marriage of Tristan and Isolde: Love, Marriage, and Adultery in Eilhart von Oberg’sTristrant(before 1190)
Authors: Seelye Martin Jonathan
Published: December 2020

The medieval legend of Tristan and Isolde is typically read as a celebration of adulterous love. This interpretation is often connected to outdated but still-widespread notions of courtly love as necessarily adulterous, unfulfilled, and deadly. This essay challenges this interpretation through an examination of one of the earliest versions of the Tristan romance, Eilhart von Oberg’s Tristrant. The essay argues that Eilhart’s romance is under the sway of a medieval discourse that strongly associated love with marriage, particularly consensual marriage. It shows that Tristan and Isolde are depicted as though they were married throughout the first half of the romance, with Tristan effectively replacing his uncle as Isolde’s husband. Scenes from the second half of the romance, in which the lovers engage in clearly adulterous behaviour, appear in a negative light that ultimately physically destroys both figures. Far from celebrating adultery, the Tristrant advocates for love in marriage.

The Ambiguity of Subversion
Authors: Vogler Gisli
Published: December 2020

This article explores subversion as a practice of resistance and draws on the example of subversive radio for illustration. Radio became an important site of power struggles in the twentieth century, often placed in the service of both resistance and oppression. An examination of subversive acts in radio broadcasting, I argue, helps shift the focus away from the myths of heroic resistance, directing attention to the uncertainties encountered by the subversive actor. To make this argument, I build on Frantz Fanon’s influential work on the resistant potential of radio and engage with literature on subversion and everyday resistance. The article illustrates the ambiguity of subversion on the case study of Radio Bantu, a broadcaster of ethnic-specific radio programmes established by the South African apartheid regime.
MANHWA AS A SOURCE OF THE EXTRALINGUISTIC INFORMATION FOR BACKGROUND KNOWLEDGE FORMATION WHILE TEACHING KOREAN TO RUSSIAN-SPEAKING STUDENTS
Authors:   State Academic University for the Humanities (GAUGN), Voronina L. A.
Published: December 2020

Manhwa as an authentic material is explored here as a source of extralinguistic information helping to form the background knowledge of Russian-speaking students while teaching the Korean language. At the same time, manhwa is a poly-code source consisting of text and visual components. Study of the relevant sources showed that due to their special structural organization and functionality, manhwa have a number of advantages for the effective assimilation of non-linguistic information by students. It is argued that students faster penetrate the extralinguistic information through the manhwa that promotes awareness of a specific situation of communication and understanding. It is shown that extralinguistic information is contained in a verbal component, such as the author's words in the frame, describing, for example, the place of communication or the mood of the characters. Also it may be contained in the characters' lines in the phylacter, when situationally and communicatively conditioned speech is clearly transmitted. It is stated that the association of the verbal component with specific communication conditions, that form the parameters of the communicative situation in Korean, is carried out at the expense of the visual component. At the same time, the image shows a manhwa character speaking Korean as a participant of communication, outwardly corresponding to his situational role, while emotional form of communication is transmitted through the body language. Characters are depicted in a certain body position, with a drawn facial expression indicating a certain emotional state, which is traditionally an important point in understanding what is happening in the Korean context. The author concludes that other paralinguistic means also convey emotionality in manhwa, namely: 1) caption, 2) phylacter form, 3) color and graphic phylacter filling, 4) sound effects, 5) background effects, 6) tone effects, 7) screen tone.
Synthesis of the law of optimal control of the system of active dynamic stabilization of the movement of a self-propelled machine with a mounted working body
Authors: Sirotin P. V
Published: December 2020

The paper is devoted to the development of systems and technical devices for reduction of dynamic loads acting on operators and the supporting system of self-propelled vehicles. The goal of the paper is to develop an algorithm and a law of optimal control of the stabilization system. The set of tasks to be solved for this is determined, the requirements for the information field are highlighted, the element base of the stabilization system is substantiated. The problem of optimal control of the stabilization system is formulated. The development of a law of control of the stabilization system of the movement of self-propelled wheeled vehicles based on the principle of active inertial vibration damping is presented. The law of optimal control of the stabilization system with the possibility of correcting the requirements for attenuation and the type of transient process was developed. On the basis of quadratic integral criteria, the indicators for assessing the quality of system control are distinguished. It is substantiated that for the system of stabilization of the harvester body it is necessary to regulate the output variables, such as the angular velocity of the body and the angle of the longitudinal inclination of the harvester body. A linearized model of the longitudinal-angular motion of the combine is considered, the equations that connect the laws of the disturbed motion of the body and the law of optimal control are presented. With the help of simulation modeling, the effectiveness of the proposed stabilization method and the law of control of the stabilization system in terms of reducing the longitudinal angles of inclination of the body when driving on an asphalt-concrete highway and a dirt road are shown. The effectiveness of the proposed law of control for suppressing the pitch of the combine body during emergency braking is shown. The calculated values of the power spent on control of the stabilization system for the considered driving modes are given. On the basis of calculations, it is shown that in the total energy balance of the combine, the power consumption for control is insignificant, which confirms the efficiency of the proposed stabilization method and the law of control. Conclusions are drawn, stages and directions of further research are determined.

Published: December 2020

We present an automated pipeline for the generation of synthetic datasets for six-dimension (6D) object pose estimation. Therefore, a completely automated generation process based on predefined settings is developed, which enables the user to create large datasets with a minimum of interaction and which is feasible for applications with a high object variance. The pipeline is based on the Unreal 4 (UE4) game engine and provides a high variation for domain randomization, such as object appearance, ambient lighting, camera-object transformation and distractor density. In addition to the object pose and bounding box, the metadata includes all randomization parameters, which enables further studies on randomization parameter tuning. The developed workflow is adaptable to other 3D objects and UE4 environments. An exemplary dataset is provided including five objects of the Yale-CMU-Berkeley (YCB) object set. The datasets consist of 6 million subsegments using 97 rendering locations in 12 different UE4 environments. Each dataset subsegment includes one RGB image, one depth image and one class segmentation image at pixel-level.
Detecting Similar Versions of Software by Learning with Logistic Regression on Binary Opcode Information
Authors: Lim Hyun-il
Published: December 2020

Logistic regression is widely used in decision problems to classify inputs through training from the previously known training data. In this paper, we propose an approach to detecting similar versions of software by learning with logistic regression on binary opcode information. Because the binary opcode information has detailed information for executing software on an individual machine, the learning from the binary opcode information can provide effective information in detecting similar versions of software. To evaluate the proposed approach, we experiment with two Java applications. The experimental results showed that the proposed logistic regression model can accurately detect similar versions of software after learning from training data. The proposed logistic regression model is expected to be applied in applications for comparing and detecting similar versions of software.
Secure Server Key Management Designs for the Public Cloud
Authors: Foltz Kevin , Simpson William R.
Published: December 2020

The Enterprise Level Security (ELS) model focuses on designing secure, distributed web-based systems starting from basic principles. One area of ELS that poses significant design challenges is protection of web server private keys in a public cloud. Web server private keys are of critical importance because they control who can act as the server to represent the enterprise. This includes responding to requests as well as making requests within the enterprise and to its partners. The cloud provider is not part of this trusted network of servers, so the cloud provider should not have access to server private keys. However, current cloud systems are designed to allow cloud providers free access to server private keys. This paper proposes design solutions to securely manage private keys in a public cloud. An examination of commonly used approaches demonstrates the ease with which cloud providers can currently control server private keys. Two designs are proposed to prevent cloud provider access to keys, and their implementation issues are discussed.
Joint User Clustering and Power Allocation for Vehicular Communications

Published: December 2020

Device-to-device (D2D) communication has emerged as a promising concept for supporting the vehicular networks, which can efficient and reliable enhance cellular network. In this paper, we discuss two different design criteria for vehicular networks. They are maximizing overall vehicle-to-infrastructure (V2I) link throughput while guaranteeing the minimum reliability for each vehicle-to-vehicle (V2V) link, and maximizing the minimum throughput of all V2V links under the constraints of minimum V2I link throughput requirements. Because both of these problems is an mixed integer non-linear programming problem, we solve these problems in two steps, i.e., by first clustering D2D users into clusters and then optimizing their respective power allocations. Specifically, we first propose a spectral clustering (SC) method for D2D users clustering. Then, two power allocation algorithms are developed to maximize the sum V2I link throughput and maximize the minimum V2V link throughput, respectively. The effectiveness of proposed resource allocation algorithms is validated by computer simulation.
Order-Preserving and Efficient One-to-Many Search on Encrypted Data
Authors: Hu Dongping , Yin Aihua , Yan Huaying , Long Tao
Published: December 2020

Order-preserving encryption (OPE) is an useful tool in cloud computing as it allows untrustworthy server to execute range query or exact keyword search directly on the ciphertexts. It only requires sub-linear time in the data size while the queries are occurred. This advantage is very suitable in the cloud where the data volume is huge. However, the order-preserving encryption is deterministic and it leaks the plaintexts’ order and its distribution. In this paper, we propose an one-to-many OPE by taking into account the security and the efficiency. For a given plaintext, the encryption algorithm firstly determines the corresponding ciphertext gap by performing binary search on ciphertext space and plaintext space at the same time. An exact sample algorithm for negative hypergeometric distribution is used to fix the size of the gap. Lastly a value in the gap is randomly chosen as the mapping of the given plaintext. It is proven that our scheme is more secure than deterministic OPE with realizing efficient search. In particular, a practical and exact sampling algorithm for the negative hypergeometric distribution (NHGD) is first proposed.

Authors: Peng Yueqi , Liu Yunqing , Li Qi
Published: December 2020

Aiming at the uneven random coverage distribution of wireless sensor networks sensor nodes, the sparrow search algorithm (SSA) is used to optimize the node coverage of wireless sensor networks. To improve the global search capability of SSA, the algorithm is improved and applied to the wireless sensor networks of bridge monitoring. For enhancing the coverage of the wireless sensor networks, this article uses two improved methods. One is to use the good point set theory to make the initial population evenly distributed; another is to introduce a weight factor to speed up its convergence. The experiments have proved the reliability and rationality of the algorithm. The improved algorithm is superior to other meta-heuristic algorithms and provides a new idea for optimizing bridge monitoring wireless sensor networks coverage.

Judges Are from Mars, Pro Se Litigants Are from Venus: Predicting Decisions from Lay Text
Authors: Branting Karl , Balhana Carlos , Pfeifer Craig , Aberdeen John , Brown Bradford
Published: December 2020

Access to justice could be significantly expanded if decision support systems were able to accurately interpret statements of fact by pro se (self-represented) litigants. Prior research, which has demonstrated that case decisions can often be predicted by machine-learning models trained on judges’ statements of facts, suggests the hypothesis that these same learning algorithms could be effectively applied to pro se litigants’ fact statements. However, there has been a dearth of corpora on which to test this hypothesis. This paper describes an experiment testing the ability to predict the outcome of pro se litigants’ complaints on a corpus of 5,842 cases initiated by citizen complaints. The results of this experiment were strikingly negative, suggesting that fact statements by unguided pro se litigants are far less amenable to simple machine-learning techniques than judges’ texts and appearing to disconfirm the hypothesis above.
Sleeping Beauties in Case Law
Authors: Hernandez Serrano Pedro V. , Moodley Kody , Van Dijck Gijs , Dumontier Michel
Published: December 2020

A challenge in computational legal research is the quantitative assessment of “relevance” in a network of court decisions. The term “sleeping beauty” (SB) was coined to denote an article that received almost no attention immediately after publication, but suddenly received multiple citations many years later. These publications can be identified by calculating their Beauty coefficient (B-coefficient). In this contribution, we apply approaches used for identifying SBs to decisions arising from the Court of Justice of the European Union (CJEU). We compared B-coefficients of CJEU cases with their centrality scores from classical algorithms from network analysis, finding that these measures tend to correlate. We discuss the implications of this that are interesting for legal scholars, acknowledging that future work is required to calibrate the scale of the time variable in the B-coefficient formula for finer-grained application to case law. Our study’s setup provides a foundation for new case law analytics methodologies that extends the power of traditional network analysis techniques for answering questions about the behavior of European courts.

During the reproductive age, 75% of women experience at least one episode of vulvovaginal candidiasis (VVC) and 40–50% of women experience two or more episodes. Recurrent VVC is referred to as at least four episodes of the disease within a 12-month period. The aim of this paper is to review the etiology, pathogenesis, clinical signs, diagnosis, and treatment for VVC. Both domestic and foreign published data are analyzed. It is now recognized that urogenital disorders and systemic comorbidities are the key predisposing factors to recurrent VVC. Other risk factors include the use of broad-spectrum antibiotics, immunosuppressants, and hormone replacement therapy, endocrine disorders, and intestinal Candida persistence. Intravaginal medications are the preferred treatment for VVC. A 6-month maintenance therapy reduces the rate of VVC recurrences by 90%. Further studies on the etiopathogenesis of recurrent VVC will improve treatment efficacy.

The paper reviews current data on lichen ruber planus, a disease characterized by multifactorial pathogenesis, polymorphic clinical symptoms, severe long recurrent course, and a significant resistance to treatment. In the last decades, a substantial growth in the prevalence of this dermatosis is observed. Moreover, the rate of atypical cases also increases. The most common symptoms at disease onset are a generalized rash, severe itching, and malaise. Many patients present with acute clinical signs. Patients with the different forms of the disease (in particular, those with oral lichen planus) report on the significant reduction in the quality of life. The authors describe the specificity of clinical polymorphism, the variability of clinical manifestations and HLA system in annular lichen planus. The aim of this paper is to summarize currently available data considering the diversity of clinical variants which are required for the understanding of the pathogenesis to improve the diagnosis in difficult cases and to control its course. The authors also address a case study of annular lichen planus in a 63-year-old woman. KEYWORDS: lichen ruber planus, dermatosis, histopathology, HLA system.

This paper addresses the etiology, epidemiology, clinical manifestations, diagnostics and treatment for larva migrans. Larva migrans occurs most commonly in tropical areas, in particular, in the Caribbean countries, Africa, South America, and Southeast Asia. Published data demonstrate the increasing number of the imported larva migrans cases in Russia. However, no clear diagnostic benchmarks are still developed. Larva migrans is accounted for by the cutaneous and/or visceral migration of the larvae of the helminths of cats and dogs which are unusual for humans and never develop in adults capable of reproduction. Clinically, the primary lesion is a 2–3-mm width erythematous serpiginous eruption filled with serous fluid. The number of eruptions complies with the number of larvae. Anti-helminthic drugs, i.e., mebendazole, thiabendazole, and albendazole, are recommended for larva migrans. The paper describes multiple cutaneous eruptions caused by larva migrans in a woman living in the northern region of the country. The authors highlight that the diagnosis was challenging. The early diagnosis and prompt treatment for helminthiases associated with cutaneous eruptions prevent gastrointestinal and other dangerous complications.

A kriminálpedagógia mint a büntetés-végrehajtás kínálkozó rendszerszervezési alapelve
Authors: Ruzsonyi Péter
Published: December 2020

A kriminálpedagógiának megközelítőleg 120 éves múltja van, azonban elfogadtatásáért még számos területen küzdenie kell. A tanulmányban meghatározzuk ennek a tudományterületnek a definícióját és tudományrendszertani helyét, valamint bemutatunk egy kanadai és egy amerikai büntetés-végrehajtási intézetet, amelyekben pedagógiai alapú reintegrációs munka folyik. Rámutatunk arra, hogy bármely alkalmazott tudománynak csak akkor van létjogosultsága, ha a gyakorlati élet igényli az elméletet; az elmélet pedig fejleszti a gyakorlatot. Napjainkra a kriminálpedagógia eljutott arra a szintre, hogy – elsősorban fiatalkorúak börtöneiben – a büntetés-végrehajtás gyakorlatának rendszerszervezési alapelve legyen. Biztosak vagyunk abban, hogy a kriminálpedagógia fejlődése érdemben hozzájárul a rendészettudomány gazdagodásához.

We are building the structures rapidly in the area where there is requirement of the structures. Every structure has its own service life. Every structure is designed by assuming its life of existence. Some of the structures gets more life than expected and some gets fail in achieving its life. Any technology or material has its limitation to withstand. Many of the structures of R.C.C. are located in Seismic prone area. The structures gets damaged due to earthquake and the structures which becomes old should be checked that whether it has the strength of existence or not. The structures should be audited timely for the safety of the human life as well as for the nearby structures. The structures can be checked by various methods of Non-Destructive Test (Rebound Hammer Test, Ultrasonic Pulse Velocity Method, Pulse Echo Method, Probe Penetration Test, Destructive Test. Rebound Hammer Test of Non-Destructive Test is used in this paper to check the strength of an institutional building. When examining the structure, this paper aims to expand the life of structure. Different techniques of Retrofitting is given to the structural member which is unsafe. By applying the retrofitting, the structure can be made safe.
