Authors: He Shangqin , Feng Xiufang
Published: December 2020

In this paper, an identical approximate regularization method is
extended to the Cauchy problem of two-dimensional heat conduction
equation, this kind of problem is severely ill-posed. The convergence
rates are obtained under a priori regularization parameter choice rule.
Numerical results are presented for two examples with smooth and
continuous but not smooth boundaries, and compared the identical
approximate regularization solutions which are displayed in paper. The
numerical results show that our method is effective, accurate and stable
to solve the ill-posed Cauchy problems.
Roman Kimliğinin Çatışmalı İnşası: "Fotokopi Romanlık" Karşısında Otantik Roman
Authors: Uştuk Ozan
Published: December 2020

Roman kimliği ve temsiline yönelik yaklaşımlar, hem akademik mecrada hem de Romanlar arasında oldukça tartışmalıdır. Etnik bağlamı öne çıkan Roman kültürel kimliği, Romanlar ile Öteki (Gaco, Roman olmayanlar) arasında meydana gelen sınır ilişkileri aracılığıyla tesis edilmektedir. Bu inşa, heterojen bir kültürel kimlik meydana getirmek bir yana, oldukça çatışmalı bir sürece işaret etmektedir. Kültürel kimliğin kuruluşunda önemli bir etkisi olan grup içi çatışmaların etkilerini irdelemek, yekpare kültürel söylem repertuvarlarını kaydetmenin ötesine geçen, derinlemesine ve uzun soluklu etnografik araştırmalar sayesinde mümkündür. Eleştirel etnografya yaklaşımı benimsenen bu çalışmada, Roman-Gaco kültürlerarası iletişiminde üretmiş temsili çeşitlilik bir yana, bu iletişimsel süreçler ile farklı biçimlerde ilişkilenen Romanların kendi mahalleleri içinde meydana getirdikleri grup içi çatışmalara odaklanılmıştır. Bu nedenle, “otantik” ya da “gerçek” Romanlığın ne olması gerektiğine yönelik kültürel müzakere ve çatışmanın üretmekte olduğu heterojen ve parçalı kültürel yapı, öznelerin bakış açılarına ve seslerine kulak vererek irdelenmiştir. Bu sayede araştırma öznelerinin tarihselliğini ve yaratıcılığını yadsımadan, meydana getirdikleri özgül kimlik temsillerinin hegemonik söylemlerin içinde nasıl konumlandığı incelenmiştir.
Alevi İnancında Can, Ruh Kavramı ve Nefsin Eğitimi
Authors: GÜL İbrahim
Published: December 2020

Ruh, can ve nefis sözcükleri insanın zihnini meşgul eden kavramlardır. Bu konuda bazı araştırmalar yapılmış olmasına rağmen bu kavramların mahiyeti tam olarak anlaşılmamıştır. Bu çalışmanın amacı, ruh, can ve nefis kavramlarını ele alarak açıklamaktır. Bu araştırmada söz konusu kavramların İslam-Alevi inancına ve kaynaklarında nasıl ele alındığına ilişkin açıklamalara yer verilmiştir.Bunun için bazı Alevi klasikleri incelenmiştir. Bu yönüyle düşünüldüğünde, araştırma kaynak taramaya dayalı bir çalışmadır. Çalışmadan elde edilen bulgulara göre, ruh ve can karmaşık kavramlardır. Bu konuda insana çok az bilgi verilmiştir. Can ve ruh çoğu zaman birbirinin yerine kullanılan kavramlardır. Nefs, insanı kötü işler yapmaya sürükleyen duyguları ifade eden bir kavram olarak karşımıza çıkmaktadır. İnsan, aklını ve iradesini kullanarak nefsin isteklerine engel olabilir. Yani bir bakıma her insan nefsini eğitebilir. Nefsin eğitimi ise daha çok tasavvufun konu alanına girmektedir. Alevi inancında nefsini eğiten insan,kâmil insan olarak bilinir. Kamil insanın hiçbir zaman canı ölmez. Ölen ancak onun bedenidir. Bu çalışmada, Alevi klasiklerinde can, ruh ve nefs kavramlarına bir açıklık getirilmeye çalışılırken bir bakıma İslam-Sünni mezhepleriyle de bir karşılaştırılması yapılmıştır.
Klasik Masalın Modern Masaldaki Tezahürü: Bilge Karasu'nun "Avından El Alan" Mas
Authors: Şahin Seval
Published: December 2020

Fredric Jameson, “Büyülü Anlatılar: Tür Olarak Romans” başlıklı çalışmasında, geleneksel bir anlatı formu olan romansın modern romanda nasıl farklı şekillerde ortaya çıktığı ve dönüştüğü üzerinde durur. Burada öncelikle geleneksel anlatı türleriyle ilgili çalışan Nortrop Frye, Vladimir Propp ve Lévi Strauss’un yaklaşımlarına değinir. Ona göre bu üç eleştirmenin yaklaşımındaki ortak özellik anlatılarda karakterleri dikkate almaları ve tanımlarını, türe dair özelikleri, karakter üzerinden yapmalarıdır. Bu tarz yaklaşımlar karaktere yabancılaşmayı engellediği, karakterin eylemlerini kavramsallaştırmadığı için sorunludur. Bu sebeple Jameson, incelemenin karakterlerle değil onların ruh halleri, bu ruh hallerinin eylemlerle birleşmesindeki durumlarla yapılmasını önerir.
Bu makalede Bilge Karasu’nun Göçmüş Kediler Bahçesi’nde yer alan ve “masal” olarak adlandırdığı “Avından El Alan” masalı Jameson’ın bu yönteminden yola çıkarak ele alınmıştır. Karasu’nun masalında, klasik masala ait birçok unsur kendi varlıklarını devam ettirirler. Fakat bu devam ettirmede masal, arkaik birçok anlatıya göndermeler yapan bir çağrışım alanına dönüşür. Bu çağrışımlara dil, belirli olmaktan ısrarla kaçan ifade kalıplarıyla eşlik eder. Bu şekilde masalda hem aynı anda iki masal birlikte akar hem de o masallar üzerine düşünen anlatıcının sesi, yazıya dökülür. Yazdığına doğrudan masal adını vermesi, klasik masalın unsurlarını kullanarak onu değiştiren, dönüştüren bir yapı kurması Karasu’nun masalını kendinden önce gelen masalcıların anlatısına ekleyen bir kurgu oluşturmasını da mümkün kılmıştır.
Inner differentiability and differential forms on tangentially locally linearly independent sets
Authors: Velkoska Aneta , Misajleski Zoran
Published: December 2020

The de Rham theorem gives a natural isomorphism between De Rham cohomology
and singular cohomology on a paracompact differentiable manifold. We proved
this theorem on a wider family of subsets of Euclidean space, on which we
can define inner differentiability. Here we define this family of sets called
tangentially locally linearly independent sets, propose inner
differentiability on them, postulate usual properties of differentiable real
functions and show that the integration over sets that are wider than
manifolds is possible.

Estimation of rigidity of concrete based on multi parameters using artificial bee colony optimization method with levy flight distribution
Authors: Kockal Niyazi , Aydogdu Ibrahim
Published: December 2020

The rigidity of the materials used in the structures affects most deformation
characteristics. Therefore, obtaining information about the rigidity of
materials is essential for the behavior of the structures. In the study, 32
different equations were derived by usage of eight parameters in various
combinations to estimate elastic modulus of concrete. These parameters are
compressive strength, unit weight, water-cement ratio, consistency, cement
amount, fine aggregate - course aggregate ratio and air content.
Multidimensional nonlinear regression models were generated between equation
models and test results. The optimization process is applied to solve
regression models. An improved version of Artificial Bee Colony Optimization
algorithm by adding levy flight distribution (ABC LF) is used as the
optimization method. Estimated values are compared to test results to
determine the goodness of the equations. The effectiveness of the parameters
is investigated according to the comparison as well.

Authors: Aydin Burcu , Yalcin Fusun , Ozer Ozge , Yalcin Gurhan
Published: December 2020

Marbles are secondary decomposition products formed by metamorphism of
limestone. Effective classification of marble quarries in terms of quality
enables the selection of a sustainable production method and safety
application. This evaluation is based on physico-mechanical properties of
the samples. Obtained results of physico-mechanical properties of the
marbles were statistically analyzed using Stata 14 and SPSS 21 software. The
marbles indicated mostly normal physical and mechanical properties. A strong
inverse relationship exists between Abrasion Value and Knoop Hardness
Determination that indicates a significant nonlinear relationship. Samples
were distinguished into 3 groups of close similarity and related properties.
The estimated value of the parameters is in the 95 % confidence interval.
The equation obtained by regression analysis was used for the determination
of resistance to abrasion.

Authors: Dere Paçin
Published: December 2020

The recurrence relations have a very important place for the special
polynomials such as q-Appell polynomials. In this paper, we give some
recurrence formulas that allow us a better understanding of q-Appell
polynomials. We investigate the q-Bernoulli polynomials and q-Euler
polynomials, which are q-Appell polynomials, and we obtain their recurrence
formulas by using the methods of the q-umbral calculus and the quantum
calculus. Our methods include some operators which are quite handy for
obtaining relations for the q-Appell polynomials. Especially, some
applications of q-derivative operator are used in this work.

An investigation on aluminothermic reduction of MoO3 in domestic microwave oven
Authors: Sheybani K. , Paydar M.H. , Shariat M.H. , Setoudeh N.
Published: December 2020

In the present study, feasibility of aluminothermic reduction of molybdenum oxide by microwave oven was studied. Furthermore, the effect of compaction pressure and the amount of used Al and CaO as flux on aluminothermic reduction of molybdenum oxide were investigated. Thermodynamic analysis of the corresponding reaction indicated that, aluminothermic reduction of MoO3 was possible at all temperatures. XRD patterns and thermodynamic investigation of reaction products indicated that aluminothermic reduction of molybdenum oxide progressed through the formation of intermediate phases such as Al2 (MoO4)3 and MoO2, where the final products were elemental Mo and Al2O3. Results revealed that by increasing the compaction pressure of the pellet, undesired phases of molybdenum dioxide (MoO2) and aluminum molybdate Al2(MoO4)3 can be detected among the final products. By increasing the amount of Al more than stoichiometric ratio, the intermediate phases, such as MoO2, were produced. The results indicated that by adding CaO to the MoO3-Al system, the unwanted molybdenum dioxide (MoO2) and aluminum molybdate (Al2 (MoO4)3) compounds were successfully reduced to Mo.. In the present work, metallic molybdenum could easily and successfully be separated from Al2O3 slag, as the side product of the reaction, in molten phase, based on the difference in their densities.
Effect of Mg addition on the crystallization kinetics of Zn-Al-Cu alloys
Authors: Krupiński M. , Labisz K. , Jonda E.
Published: December 2020

In this work, the main aim was to determine the effect of Mg addition on the crystallization kinetics and microstructure of Zn-10Al-1Cu alloy. The effectiveness of magnesium addition was detected on the basis of microstructure morphology investigations and changes occurring in the cooling curves of the investigated alloys. To describe the phenomena that occurred in the material during solidification under various conditions caused by a change in the chemical composition as a result of the appliance of modifiers, it was decided to use methods of thermal derivative analysis, allowing to effectively and accurately describe the crystallization kinetics of the tested materials. The scientific goal of the presented work was examination of the impact of magnesium addition and effect of the crystallization kinetics on the examined alloys. Determining the relationship between the changes in the derivative curve and the related microstructure, the influence of modifiers addition was analysed. The addition of Mg caused a shift of the solidification temperature values of phases and eutectics and monotectoid transformation (????) to lower temperature values, as well as the change of the morphology of the occurring eutectic ??+?.

Naturen som rom: Filosofisk samtale gjennom erfaring i natur
Authors: Løvoll Helga Synnevåg
Published: December 2020

In this text, nature is explored as a space for recognition, seen from an outdoor pedagogical perspective. Through guidance in outdoor living (friluftsliv) in small groups, a working form is presented that aims to inspire nature-friendly value orientation. This method of work is primarily known as an experience-based practice and is only partially articulated as a philosophical project. Inspired by Arne Johan Vetlesen’s demand for a paradigm shift in environmental ethics (Vetlesen, 2015), outdoor recreation pedagogical practice may be an answer to an interpretation of how “experiential ecocentric ethics” may be an alternative to exceeding the recognition of nature’s inherent value. Special qualities in the perception of place and space are central to understanding the uniqueness of outdoor living for the philosophical conversation. By analysing various characteristics of outdoor pedagogical practice, the value of this practice is discussed to develop a philosophical conversation. Finally, a proposal for virtues is presented to bridge the gap between philosophy, psychology and know-how.

Published: December 2020

Religious processions in secular urban spaces are a growing phenomenon that has received limited public attention in Norway. In this country, the Roman Catholic Church is a large and culturally diverse religious minority. Built on observations of processions on the major feast of Corpus Christi in six different Catholic parishes, the article discusses the use, the production, and the relational qualities of space performed by these processions, and identifies a number of overlapping projects and effects, including missionary and theological aspects, promoting unity in diversity, and creating ties to the local community as well as to other times and places.
Flyktige rom og tynne steder: En transnasjonal og spatial analyse av pentekostale migrantmenigheter i Norge
Authors: Eriksen Stian Sørlie
Published: December 2020

This article discusses sociocultural and theological aspects related to space and place for Christian migrants and Pentecostal migrant churches in Norway. The article addresses how Christian migrants and migrant congregations relate to and produce dimensions of place and space within their migratory contexts, drawing from contextual examples and theoretical perspectives on space and place. Thus, spatial perspectives provide frameworks for discussing issues of belonging, religious discourses, and spirituality with regard to the migrant communities themselves, in the wider religious landscape, and in society. In particular, we ask how experiences of spatial and social constraints help shed light on how migrants and migrant churches seek to make home in new contexts. This also relates to how these migrants and churches navigate within the translocal, symbolic and virtual landscapes of Pentecostal transnational networks. Finally, the article addresses spatial dimensions of these churches and networks’ aims to bring about spiritual and societal transformation.
Fra det religiøse og sekulære til det hellige og profane: «Det religiøse», «det sekulære» og «det hellige» som romlige kategorier sett i lys av begrepshistorie og filosofisk arkeologi
Authors: Lillebø Jonas Gamborg
Published: December 2020

The aim of this article is twofold. In the first part, I aim to show how the categories ‘religion’ and ‘secularity’ are separated by being connected to different spheres or spaces. The separation of a ‘religious sphere’, a ‘secular sphere’, a ‘political sphere’, etc. is the ideological outcome of a period in the history of thought we call modernity. Through the tradition of ‘conceptual history’ this separation can, however, be deconstructed. The modern break with the premodern past was less radical than its ideological representation. As I try to show, the works of Reinhart Koselleck and others have demonstrated that the concepts and logics of modernity were partly inherited from what modernity rejected. Thus the modern separation of politics as a specific ‘secular sphere’ (secularism) was just a reversal of Christian political theology. The question is, however, whether beneath the level of conceptual history there is another historical strata that conceptual history cannot deal with. In the second part of the article, I discuss through the work of Giorgio Agamben and his ‘philosophical archaeology’ how ‘any’ logics of separation stems from archaic religion. The distinction between ‘the religious’ and ‘the secular’ sphere thus seems to be a less fundamental one than the archaic distinction between ‘the sacred’ and ‘the profane’. My claim is then not ony that the separation of spheres in modern thinking is conceptually connected to and dependent on Christian theology, but that it also reproduces archaic thought.

The method of primary processing of poorly structured medical data
Authors:   Sumy State University, Bychko Dmytro , Shendryk Vira ,   Sumy State University, Parfenenko Yuliia ,   Sumy State University
Published: December 2020

The article deals with the approach to the primary processing of poorly structured medical protocol textual data stored and disseminated as pdf files. The relevance of this work is due to the lack of a universal structure for the presentation of medical protocols and methods of their processing. In the course of the work, the problem of primary processing of clinical protocol data was solved by the example of a unified clinical protocol of primary, secondary (specialized) and tertiary (highly specialized) medical care. The method of primary data processing was developed to create a clear structure of the symptoms of the disease. The first step in structuring clinical protocol data is to divide the protocol information into four basic parts, which allows it to be quickly converted to other formats. This process is implemented using an algorithm developed in C # programming language. The proposed algorithm parses the information from a pdf file and converts it to a txt file. After that, the received information is processed, which consists in the syntactic analysis of the text of the protocol and selection of the structural parts of the protocol corresponding to the headings of the sections: title page; introduction; a list of abbreviations used in the protocol; the main part of the protocol; list of literary sources. The identification of the disease name in the medical protocol is performed by comparing the protocol data and the list of disease names, presented in the world classification MKH-10. The headings “Introduction”, “List of abbreviations used in the protocol” and the main part of the protocol were analyzed and the algorithm for removing uninformed sections from the beginning of the protocol, for example, literature sources, was proposed. An algorithm for finding information in the main part of the medical protocol by processing input data by: tables, diagrams, headings, words, phrases and special symbols are also proposed. As a result of the clinical protocol processing algorithms, a new clinical protocol file is generated, which is three times smaller than the original file. It contains only meaningful information from clinical protocols that will speed up further work on this file, namely its use in medical decision support. The disease card based on a medical protocol in JSON format is presented.

The concept of creating a multi-level mobile personalized system for fighting viral diseases, in particular Covid-19, was developed. Using the integration of the Internet of Things, Cloud Computing and Big Data technologies, the system involves a combination of two architectures: client-server and publication-subscription. The advantage of the system is the permanent help with viral diseases, namely on communication, information, and medical stages. The smart city concept in the context of viral disease control focuses on the application of Big Data analysis methods and the improvement of forecasting procedures and emergency treatment protocols. Using different technologies, cloud server stores the positioning data obtained from different devices, and the application accesses API to display and analyze the positioning data in real time. Due to the technologies combination, internal and external positioning can be used with a certain accuracy degree, being useful for various medical and emergency situations and analysis and the following processing by other smart city information systems. The result of the given investigation is the development of the conceptual model of multi-level mobile personalized health status monitoring system used for intellectual data analysis, prediction, treatment and prevention of viral diseases such as Covid-19 in modern “smart city”.
The Design Of The Adana Yüreğir Coastal Park And Its Role In The Plannıng Of Urban Recreatıon Areas
Authors: ÇORBACI Ömer Lütfü
Published: December 2020

Today’s most important problem in terms of urban planning is rapidly diminishing urban green areas due to rapidly increasing housing. In urban planning, urban green space systems play an important role in meeting the recreational needs of people living in the city. Thus, within the urban green space system, urban parks contribute to the unification of disconnected biotopes in the urban green space system, the development of green corridor lines, and the sustainability of wildlife in the city as well as its benefits such as providing an aesthetic look, reducing noise, cleaning air, creating a microclimate, and reducing the pollution. In this study, “Adana Coastal Park Project” has been prepared for an urban green area in Yüreğir, Adana, which was reserved by Yüreğir Municipality and its function in Adana's urban green space system has been evaluated. In the evaluations, criteria such as activity, functions, materials used, aesthetic design principles, comfort, image, security, and maintenance have been taken into consideration.

Dental ceramics have an excellent ability to reproduce natural teeth appearance, but once the substrate has an altered coloration, it is necessary to mask this intercurrence, considering the characteristics of the ceramic and cement selected. This article aims to present a clinical case of rehabilitation with ceramic laminates to mask a darkened central incisor by planning a more opaque porcelain structure under a translucent contact lens. A female patient sought dental care complaining of dissatisfaction with smile aesthetics. It was clinically identified the presence of a Class IV darkened restoration in composite resin in element 11. In treatment planning harmony in the shape and color of elements 11 and 21 was aimed at through lithium disilicate lenses. An opaque intermediate structure was used to cover the darkening in tooth 11. The double molding technique was performed to obtain the working model. Prior to cementing, the surfaces were treated. In ceramics, conditioning with 10% hydrofluoric acid and 37% phosphoric acid, silane application and universal adhesive; in dental substrate, conditioning with 37% phosphoric acid and application of universal adhesive were performed. In laminates definitive cementation Allcem Venner cement was chosen. Patient reported satisfaction with treatment final aesthetics. Thus, cementation technique of a translucent laminate over an opaque facet is a good option for masking substrates with darkened coloration.

The literature reports several materials for the restoration of endodontically treated teeth, with coronal destruction that requires an intra-root fiber post to stabilize the prosthetic part. The intra-radicular post of composite resin reinforced with fiberglass can be used as retainers in rehabilitating endodontically treated teeth due to their adhesiveness, pleasing aesthetics, and elasticity module close to the dentin less wear on the remaining structure. This clinical case reports the step-by-step application of dual resin cement (Rebilda DC Dentine - Voco) used as the cementation material of the post and material for the filling core in a single step, in an upper right lateral incisor. Moreover, it describes the advantages and indications of the post-and-core technique, also called “monobloc” which can be used in both anterior and posterior teeth. This protocol minimizes the adhesive interfaces, the chair time, and the steps of the clinical procedure.

Soil organic carbon (SOC) is an important factor for soil quality diagnosis. Physical and chemical fractionation of SOC are useful to characterize SOC, because some fractions are more sensitive indicators of the effects of different management practices. The aims of this study were (i) to determine values of SOC and different fractions of SOC at different depths and positions in an Argiudoll of the Argentinian Pampas under NT, and (ii) to determine the relation between physical and chemical fractions of SOC. In an experimental plot located in Chascomús, we determined SOC content, humic acids (HA), fulvic acids (FA), humins, coarse and fine particulate organic carbon (POCc and POCf) and mineral associated organic carbon (MOC), at different depths and in the row and inter-row. The content of SOC and different SOC fractions, as well as the contribution of each fraction to SOC showed a vertical variation. The contribution of HA and POCc (newer and more labile fractions) to SOC was larger in the surface than in deeper layers, while humins’ (older and more recalcitrant fraction) contribution to SOC increased with depth, and the contribution of FA, POCf and MOC to SOC remained relatively constant. There was no effect of row and inter-row in SOC content and composition. FA content was correlated to POCc, HA content to POCc and POCf and humins to MOC.

El Ca y el Mg intervienen en el crecimiento vegetal según su disponibilidad, y posiblemente su relación. Los suelos de la Región Pampeana se han considerado bien dotados de estos elementos, aunque diagnosticaron áreas con bajos contenidos. El objetivo del trabajo fue evaluar diferentes concentraciones de Ca en solución nutritiva sobre la producción de materia seca (MS), contenido de Ca y Mg en MS, y su exportación aérea en raigrás anual (Lolium multiflorum L.) y soja forrajera (Glycine max [L.] Merr). Adicionalmente, se evaluó el efecto de duplicar la concentración a igual relación Ca/Mg. Se realizó un ensayo con soluciones nutritivas de 1, 5, 9 y 12 mM Ca y 2 mM Mg. Se adicionó un tratamiento con 10 mM Ca y 4 mM Mg. Se realizaron tres cortes en raigrás y uno en soja. Se determinó que en raigrás los niveles de nutrición cálcica influyen sobre las concentraciones y exportación de Ca y Mg en MS, sin efectos sobre la producción de MS. La relación Ca/Mg ocasionalmente se relacionó con la concentración de Ca y Mg en MS y en la exportación de Ca y Mg. En soja, los niveles de nutrición cálcica influyen sobre la producción de MS, concentraciones de Ca en MS y en la exportación de Ca y Mg, mientras que no intervienen en la concentración de Mg en MS. En este cultivo, la relación Ca/Mg en solución ocasionalmente produjo efecto en la concentración de Ca en MS y en la exportación de Ca y Mg.

Objetivou-se com este trabalho determinar a degradabilidade ruminal e os parâmetros da cinética de degradação da matéria seca, matéria orgânica, proteína bruta e frações fibrosas dos fenos de Andropogon gayanus produzidos a partir de 56, 84 e 112 dias de idade. O delineamento estatístico utilizado foi o de blocos ao acaso em esquema de parcelas subdivididas, sendo cinco animais utilizados como blocos, as três idades como parcelas e sete tempos (0, 3, 6, 12, 24, 48 e 96 horas) de incubação como subparcelas. As médias foram comparadas pelo teste SNK ao nível de 5% de significância. O desaparecimento ruminal médio da matéria seca, matéria orgânica, proteína bruta e das porções fibrosas, após 96 horas de incubação ruminal, foram maiores (P<0,05) para o feno colhido aos 56 dias, quando comparado aos fenos colhidos aos 84 e 112 dias de idade. O maior potencial e taxa de degradação ruminal dos nutrientes indicam que melhores fenos de A. gayanus são obtidos aos 56 dias de idade.

Published: December 2020

Juego es un concepto presente en la escritura académica de distintos tiempos que ha sido abordado por autores de diferentes campos de conocimiento. Así, al indagar acerca de los estudios sobre el juego se hace visible un amplio espectro de producciones académicas con distintos grados de formalización (escritos, ensayos, teorías) que le reconocen distintos atributos y le asignan diferentes usos, al punto de que parecieran no hacer referencia al mismo objeto.

Este artículo presenta avances de una investigación que tiene por objetivo conocer y comprender prácticas y discursos acerca del juego en el contexto universitario. Se presenta un relevamiento en la biblioteca de la universidad seleccionada como caso a estudiar, analizando las significaciones que el concepto juego gana en los libros cuyo título lo mencionan. En un primer momento se procedió a un análisis bibliométrico registrando las producciones que lo mencionan y agrupándolas por grandes áreas de conocimiento. En un segundo momento, se seleccionan intencionalmente los libros representativos de distintas líneas de estudio recuperando el contexto en que fueron producidos para reconocer los hechos que posicionaron el juego como objeto de estudio dando origen a discursos incorporados que se intentarán desgravar.
