During the 2019 presidential election campaign, the issue of identity politics strengthened in the community. Political actors often use an identity to attract the attention and support of potential voters. The media which are supposed to be independent are actually trapped in the issue of identity politics. Reporting on online media is often influenced by the ideology and interests of media that are reflected in the framing of the news carried out by that media. This Study aims to describe the framing carried out by medcom.id in reporting the 2019 presidential election campaign. This study uses a qualitative approach with framing analysis from Robert N. Entman. The results of this study indicate that medcom.id is proven to be framing using identity politics in reporting the 2019 presidential election campaign. Identity politics framing conducted by medcom.id is news containing SARA (Ethnicity, Religion, Ancestry, and Group of People)Tahun 2019 merupakan salah satu tahun politik yang dinilai cukup panas bagi masyarakat Indonesia, pada tahun ini pemilihan presiden dan wakil presiden kembali mempertemukan Joko Widodo dan Prabowo Subianto sebagai calon presiden. Pada kampanye Pilpres 2019 kemarin, isu politik identitas menguat di masyarakat. Para aktor politik sering kali menggunakan sebuah identitas untuk menarik perhatian serta dukungan calon pemilihnya di masyarakat. Media yang seharusnya independen justru terjebak dalam isu politik identitas tersebut. Pemberitaan pada media online seringkali dipengaruhi oleh ideologi dan kepentingan pemilik media yang tergambar pada pembingkaian berita yang dilakukan oleh media tersebut. Penelitian ini bertujuan untuk menggambarkan pembingkaian yang dilakukan oleh portal berita media online medcom.id dalam memberitakan kampanye pemilihan presiden 2019. Penelitian ini menggunakan pendekatan kualitatif dengan analisis framing Robert N. Entman. Hasil penelitian menunjukkan bahwa medcom.id terbukti melakukan pembingkaian dengan menggunakan politik identitas dalam pemberitaan kampanye Pilpres 2019.

Steganography is a technique to improve the security of data, which is by inserting messages or confidential information using a medium called the host or carrier or cover. A wide variety of digital media can be used as a host, among others audio, image, video, text, header, IP datagram, and so forth. For audio steganography, the embedded audio is called stego-audio. Steganography can be cracked by using steganalysis. By exploiting the weaknesses of each steganography method. Many steganography method has been developed to increase its performance. This work proposed audio steganography scheme called Modified Enhanced Least Significant Bit (MELSB) which is modified version of Enhanced Least Significant Bit (ELSB). This method using Modified Bit Selection Rule to increase SNR and robustness of stego-audio. SNR result after applying MELSB scheme is increased. MELSB scheme also increase robustness of stego-audio. MELSB still work fine until amplification level 1.07. MELSB also work fine against noise addition better than ELSB and LSB. It give BER and CER with value 0 at SNR 33 dB. MELSB work fine in real-time condition on 802.11n WLAN if there is no transcoding and noise addition between senderâ€™s and recipientâ€™s computer.

The Eminence of Incubation in Creative Procces As The Basic Reason of Recreation Space Development at Work
Authors: Yudiarti Diena , Amelia Hani
Published: March 2020

Creative People are known to be different in their perceptions and interpretations of their work problems, depending on the characteristics of the current situation occur (Dorst & Cross, 2001). The creative process that people usually see cannot be seized by any methodology, but the creative people actually implement different types of methods. Methods have flexibility in processes, actions, and appreciations (Roozenburg & Dorst, 1998; Stempfle & Badke-Schaub, 2002). Creative people usually have unique characteristics while doing their job. They need some supportive situations or environments to embrace the imagination as they create an idea of the creative process. Sometimes, the ideas come out in unexpected situations, either in a relaxed situation or under pressure situations. The second stage of creative thinking from the four stages presented by Graham Wallas (1926) is the Incubation Stage which becomes the focus of this research. The need for the incubation stage will be used as one of the variables of the user aspect approach for leisure facility design which is the output expectation from this research for the recommendation of designing the facility in a Co-Working Space.
To the question on identification and differentiation of a philosophical zombie
Authors: Dushkin Roman
Published: March 2020

This article examines the task of identification and differentiation of a so-called “philosophical zombie” in order to form a set of operational criteria for determining the agency of artificial intelligence systems. This task can be viewed as one of the possible ways towards solution of a “hard problem of consciousness”. Despite the fact that the proposed approach alone does not solve the “hard problem”, it reveals certain aspects of neurophysiology, cybernetics and information theory towards its solution. The relevance of this task results from the more extensive implementation of artificial cognitive agents in human life – the boundary that distinguishes an intelligent creature from an artificial cognitive agent, endows an object with agency. Therefore, the development of more complicated artificial cognitive agents (artificial intelligence systems) would ultimately lead to a contentious debate on the topic. The author attempts to introduce the procedure of identification of a philosophical zombie and its restrictions, as well as explores the idea whether or not the artificial cognitive agents would obtain qualia. The article is valuable of those interested in artificial intelligence in all of its aspects, as well as in the philosophy of consciousness.
To the definition of poetic ontologies
Authors: Dorozhkin Egor Leonidovich
Published: March 2020

This article examines the main vector of development of ontologies in European philosophy of the XX century. The subject of this research is the concept of “poetic ontologies”, proposed by Alan Badiou applicable to fundamental in their essence projects of Martin Heidegger and Gilles Deleuze, An attempt is made to explicate the specific conceptual meaning of the poetic in the referred projects by revealing its differences from poetry in a narrow sense of versification, and its correspondence with the fact that in Deleuze’s texts it received a name of schizophrenic language. Alongside the general scientific methods of description, analysis and synthesis, the author also used the hermeneutic method and comparative analysis. Application of the concept of “poetic ontologies” in respect to the projects of M. Heidegger and G. Deleuze, found its substantiation and legitimacy in the course of this research. The main conclusion consists in elucidation of the constructive link of the poetic with the certain interpretation of existence, known as nature and opening a prospect for the nonclassical forms of reasoning.
Experimental assessment of new insulation coatings for lean burn spark-ignited engines
Authors: Chérel Jérôme , Zaccardi Jean-Marc , Bouteiller Bernard , Allimant Alain
Published: March 2020

Clean and highly efficient internal combustion engines will still be necessary in the future to meet the ambitious CO2 emissions reduction targets set for light-duty vehicles. The maximal efficiency of stoichiometric Spark-Ignited (SI) gasoline engines has been steadily increasing in recent years but remains limited by the important relative share of cooling losses. Low heat rejection engines using ceramic barrier coatings have been presented in the past but smart insulation coatings are gaining a renewed interest as a more promising way to further increase the engine maximal thermal efficiency. This article is highlighting some important effects of smart insulation coatings developed for lean-burn spark-ignited gasoline engines. Five different coatings with low heat conductivity and capacity are applied on aluminum engine parts with the atmospheric plasma spray technique and are tested with two different engines. The laser induced phosphorescence technique is firstly used in an optical single cylinder engine to quantify the thermal performance of these coatings in terms of temperature swing during combustion. A maximal increase in the piston surface temperature of around 100 °C is measured at low load, confirming thus the expected impact of the low heat conductivity and capacity, and suggesting thus a positive impact on fuel consumption. Thanks to the tests performed with a similar metal single cylinder engine, it is shown that the unburned hydrocarbon emissions can significantly increase by up to 25% if the open porosity on top of the coating is not properly sealed, while the surface roughness has no impact on these emissions. When applied on both the piston and the cylinder head, the optimized coating displays some distinct effects on the maximal heat release rate and NOx emissions, indicating that the thermal environment inside the combustion chamber is modified during combustion. Thanks to the temperature swing between cold and hot engine phases the volumetric efficiency can also be kept constant. However, no increase in efficiency can be measured with this optimized coating which suggests that the heat balance is not affected only by the reduction in the temperature differential between the walls and the gas.

Authors: Karamguzhinova A. E. , Kuznetsova V. N. , Savinkin V. V. , Koptyaev D. A.
Published: March 2020

Introduction.The problem of increasing the efficiency of power machines is important to develop a new design of the main elements or drive with the possibility of widespread use of hybrid drives. To preserve the power characteristics of the drive and its technical and operational indicators, the authors consider a hybrid with the available electric and hydraulic drive parts that form a complex synergistic mechanism as an alternative. The proposed combined tracking system with the specified parameters allows for the efficient operation of the drive of many machines.

Materials and methods.The paper presented the results of an analytical study, the prospects for the development of mechatronic systems in engineering and technological complexes. The research also identified the industry area with a high development potential for mechatronic and hybrid drives. The authors formulated the problem of designing and developing hybrid drives due to the fact that there was no single method for substantiating the energy efficiency indicators of a power hybrid drive that ensured the interaction of two dissimilar systems (electric drive and hydraulic drive with fundamentally different parameters).

Results. Therefore, the authors conducted the analysis of the structural, technological and operational parameters of the hybrid drive systems and proposed a combined servo drive system.

Discussion and conclusions. The authors prove and justify the extensive possibilities of using hybrid drives as an alternative to pneumatic and hydraulic drives The results of the research allow specifying the directions and prospects of using hybrid synergetic drives and systems for the functioning of working equipment, machines and complexes.

CITY-FORMING ENTERPRISES: RELIABILITY AND REDUCED COSTS OF THE PASSENGERS’ TRANSPORTATION
Authors: Kurganov V. M. , Gryaznov M. V. , Davydov K. A.
Published: March 2020

Introduction. The paper substantiates the relevance of reducing costs for regular passenger traffic and increasing their reliability in relation to cities with city-forming enterprises. The organizational and technological specificity of the regular route network of urban transport in such cities is disclosed. The authors propose a method for organizing regular transportation routes based on a rational combination of basic routes that require boarding and disembarking passengers only at stopping points and backup routes with boarding and disembarking passengers in any place not prohibited by the rules of road traffic. The authors demonstrate route network optimization of the regular passenger transportation using the proposed economic and mathematical model and taking into account the costs of forming the infrastructure for organizing traffic on backup routes, operating costs of transportation, as well as the cost of eliminating failures in urban transport. The developed mathematical model for assessing the reliability of regular passenger transportation differs from the well-known models, which take into account the availability of backup routes in the regular route network. The research proves the practical implementation of the proposed recommendations by the example of public transport routes in Magnitogorsk.

Materials and methods. The authors used the analysis of scientific and regulatory literature; economic and mathematical modeling of transport processes; methods for calculating the reliability of technical and transport systems; the statistical, technical and economic system analysis.

Results. As a result, the authors revealed the optimization of the economic and mathematical model of the regular passenger transportation in cities with city-forming enterprises and a mathematical model for assessing the reliability of regular passenger transportation. Moreover, the paper presented practical recommendations on the organization of reserve routes for regular passenger transport on the example of Magnitogorsk.

Discussion and conclusions. By the implementation of theoretical principles, mathematical models and recommendations developed in the course of the research, the authors show the effect of implementation and the possibility to obtain new scientific results. Moreover, the authors demonstrate the formation of an additional volume of traffic by 178 thousand passengers a year, an increase in the speed of communication by 7 km per hour, a decrease in the cost of transporting one passenger by 7% and an increase in reliability by 1.14.

Accounting of Economic Content and Legal Form of Lease Relations in Timber Logging
Authors: Ulyasheva L. G.
Published: March 2020

Qualitative representation in the accounting space of economic and legal characteristics of various events and objects is currently the problem that has not fully been resolved yet, despite the action in Russian and international accounting practice of the principle of priority of content over the form. The article is devoted to improving the veracity of accounting information about forest resources used in the logging business on lease terms. The methodological basis of the study was the conceptual framework of IFRS, the provisions of Russian accounting standards, as well as the postulates about accounting as a means of modeling the economic activity of any organization and the mandatory relationship of the form and content. The use of methods of historical actualization, analysis, comparison, synthesis, modeling, analogy and generalization provided an opportunity to develop an approach that allows you to reach a compromise in the accounting reflection of the economic content and legal form of lease relations in the logging sector. The result of the study was a refined accounting interpretation of the economic essence of the lease agreement for logging. The theoretical significance of the study is to justify the need to re-qualify the relationship between the state and the logger. The practical application of the proposed recommendations will improve the quality of the indicators generated by the accounting system, provided to all categories of users.

Samuel, the ruler of Bulgaria from the turn of the tenth and eleventh centuries is without a doubt a significant figure in the history of his country, having left a clear mark on its relations with the Byzantine Empire. It was he who challenged the Byzantines, who occupied a considerable part of Bulgaria in 971. Over the course of several decades, he was first wrenching Bulgarian territories from the Byzantine hands and subsequently defended his possessions with great determination. It was only several years after his death (1014) that the Bulgarian state fell into Byzantine hands (1018), ushering an almost hundred and seventy yearperiod of its nonexistence – the time of Byzantine captivity.

Information included in the 12th‑century Byzantine sources (Nicephor Bryennios, Anna Komnene, John Zonaras, Michael Glykas, The Life of Nikon Metanoeite”), analysed in the present article and relating to Samuel are focused on the two fundamental questions, specifically the circumstances in which he had taken the reins of power and the military activity he conducted against Byzantium. The portrayal of the Bulgarian ruler included therein was on the one hand influenced by the trend present in the Byzantine literature to diminish the successes of the Empire’s enemies by indicating their causes were to be found on the Byzantine side, and on the other by the fact that the Bulgarians became subjects of the Byzantine ruler. Some of them entered into the elite of the Byzantine society, sometimes through familial connections. In these circumstances, it was better to be related to Samuel the Basileus, rather than to Samuel the barbarian.

Indexing Schulz’s fiction is a joyful activity, which is easy to realize. Whoever has not tried it yet, definitely should. Those who do not wish to give it a try must draw satisfaction from reading the following reports and explanations: (1) Indexing is an active way of approaching a text, in particular a literary work which nowadays is rarely supplemented with an index. It is something more than just reading, although without perusing a text first, it is impossible to do it. Indexing is an attempt to spread over the perused text a network that consists of the elements which come from it. An index is a kind of map: it reflects the text, and consequently the world in the text, which means that it can function as a guide; (2) A crucial problem is that indexing is an activity on the borderline separating the represented world and the language which represents it. This borderline is very often fluid and indefinite, hence misleading. The indexer must continually return to the fundamental question whether he or she refers to the thing or to the word which names it (and creates it in literature); (3) The indexer’s starting point is always the textum. Moving word by word, the indexer slowly turns into a spokesperson of the represented world, by self-appointment representing the interest of the literary being. Indexing that grows out of reading is a proto-interpretation. Thus, in indexing a bias (and a sense of commitment) are natural and even desirable since they make it possible to come up with a “hypothesis of the hidden whole of the work” which, close to the text, starts to organize reading and work on the index; (4) If indexing is to be something more than just making a register of linguistic forms which are evidently present in the textum, but tries to reach further, beyond words (and particularly to the world which goes beyond itself), it should take into consideration a state which may be called the state of ontological ebullition. It encompasses both the represented world and the passages between that world and the textum – the act of its creation and the act of the reader’s transgression of that creation at the moments when, to use Schulz’s metaphor, “it diffuses beyond its boundaries.” The indexes allow us to identify those passages as they atomize the textum, dividing the literary tissue into single fibers. This means that the object of indexing is not only the textum and the represented world, but also, and perhaps even in the first place, the writer’s imagination which stations (and rules) on the borderline between words and things.

Se diseña y se hace referencia de forma escalonada mediante ensayos de laboratorio la presencia de fisuras y grietas en losas apoyadas. Se incorpora vidrio molido para controlar la contracción plástica con distintas dosificaciones de vidrio molido de coloración verde y marrón, adoptando 4 tipos de mezcla (1% y 5% en relación al volumen del agregado fino), ensayadas a compresión, flexión y fisuración, para una resistencia fʼc=210 Kg/cm2. El método empleado fue el deductivo con orientación aplicada y enfoque cuantitativo. El instrumento de recolección de datos fue retrolectivo, descriptivo, correlacional y explicativo. El diseño fue el experimental, longitudinal, prospectivo y el estudio de cohorte (causa-efecto). Los resultados obtenidos muestran que en los ensayos de potencial de fisuración en losas, cuando se le incorpora 1% de vidrio molido (verde o marrón), disminuyen un 83,32% y 85.18% respectivamente; así mismo, con 5% de vidrio molido (verde o marrón) disminuye un 85.82% y 88.88% respectivamente. Para esta investigación, se concluye que el vidrio molido aporta significativamente a la reducción de fisuras y grietas en una losa de hormigón y, por consiguiente, controla la contracción plástica.

Se estudia el hormigón de alta densidad reforzado con escoria de cobre como parte del agregado fino para mejorar sus propiedades mecánicas y obtener barreras protectoras para atenuar las radiaciones ionizantes hasta niveles aceptables, así como una mezcla con mayor trabajabilidad y homogeneidad. El método empleado fue el deductivo con orientación aplicada y enfoque cuantitativo. El instrumento de recolección de datos fue retrolectivo, descriptivo, correlacional y explicativo. El diseño fue el experimental, longitudinal, prospectivo y el estudio de cohorte (causa-efecto). Se diseña un hormigón con patrón de resistencia f 'c=210 kg/cm2, con 5 tipos de mezclas adicionales para ser comparados con la mezcla patrón, con diferentes porcentajes de la escoria de cobre (15%, 30% ,50%,80% y 100%) como sustitución parcial del agregado fino. La muestra conformada por 144 probetas con medidas 20cmx10cm, para los ensayos de resistencia a la compresión y tracción a edades son de 3, 7, 14 y 28 días. También se elaboró 18 placas con medidas de 20cmx20cm de espesores variables (1.5 cm, 2 cm, 2.5 cm), para realizar los ensayos de radiación directa-dosimetría exponiéndolos a una intensidad constante de Rayos X. El estudio determinó que a medida que se aumenta la dosificación del porcentaje de escoria de cobre aumenta la densidad del hormigón; la resistencia a la compresión y la resistencia a la tracción se incrementan hasta la incorporación de un 30% de escoria de cobre, después de ese porcentaje las resistencias disminuyen gradualmente. En la atenuación de las radiaciones ionizantes se observó que a mayor porcentaje de escoria de cobre mejoran las barreras protectoras brindando una mayor protección radiológica. El estudio determinó que la propuesta del diseño óptimo consiste en la dosificación de 50% de escoria de cobre y 50% de agregado fino, con un espesor de losa de 2.5 cm, grado de homogeneidad de 2.51%, porcentaje de atenuación de radiación ionizante 93.28%, densidad 2699.27 kg/m3, resistencia a la comprensión 376.70 kg/cm2 y a la tracción de 30.13 kg/m3.
