Authors: Gogolák László , Csikós Sándor , Molnár Tamás , Szuchy Péter , Bíró István , Sárosi József
Published: December 2019

The automotive industry was always characterized by innovation and the use of cutting edge technology. Daily we can see vehicles packed with technological advancements. The main focus of the current technological trend is electric drives. With the rise in popularity of electric cars more types of vehicles are adapting electric drives. In the case of airplanes the standards are higher than in the case of cars so the emphasis of research and innovation is greater. This paper presents a list of the challenges electric aircrafts face and their potential solutions. Currently many of these problems currently only have partial solutions if any. There is also a comparison between the properties of materials used and the expectations for hybrid aircraft. A comprehensive model was created taking into account the criteria set for hybrid and electric aircraft. With the aid of the model the effect of the most important components on efficiency can be assessed.

Published: December 2019

In this article we presented the casual photographic records of butterflies (Lepidoptera, Papilionoidea) made along with the studies on the Odonata fauna in 33 localities of two eastern provinces of Cambodia, Ratanakiri and Mondilkiri in 2013-2018. The butterflies were photographed in purely natural conditions without any restriction of their freedom and mobility, using two cameras, Olympus Camedia C8080 and Canon EOS 350D, the latter with the lens Sigma AF 24-70 mm F2.8 EX DG MACRO. Coordinates were obtained with Garmine eTrex H personal GPS navigator and revised with Google Earth; elevations were retrieved from Google Earth. In total, we identified 118 and provisionally identified five species; 19 species (Abisara cf. bifasciata, Poritia cf. hewitsoni, Ahmetia achaja, Arhopala nicevillei, Sinthusa chandrana, Virachola sp. cf. kessuma, Zizeera maha, Tirumala limniace, Junonia hierta, Yoma sabina, Terinos clarissa, Euripus nyctelius, Lethe rohria, Bibasis sena, Caprona agama, C. alida, Aeromachus cf. pygmaeus, Gangara thyrsis, and Udaspes folus) and one subspecies (Kallima inachus alboinachus) are reported for Cambodia for the first time. We also illustrated these species as well as some more provisionally identified and unidentified for this region.
KOMODIFIKASI PEKERJA PADA YOUTUBER PEMULA DAN UNDERRATED (Studi Kasus YouTube Indonesia)
Authors: Ulya Himmatul
Published: December 2019

The purpose of this research is to reveal commodification form and process which experienced by beginner and underrated YouTuber in Indonesia. This research uses a critical paradigm with qualitative approach through observation and indepth interview by developing political economy communication through especially commodification of labor as a theoritical framework. The development of new media especially YouTube, became on of the attractions for the community to plunge as creative workers in the digital world. YouTuber also known as content creator is profession that is in great demand by the millenial generation it can upload content video that can provide commercial benefits and popularity. The monetization and copyright feature on the YouTube platform was not able to be obtained by all creators. This research shows the commodification process that is not realized by creators, especially beginner and underrated YouTuber through the YouTube partnership programs (YPP). The commodification form experienced by creators is the exploitation of content ownership and digital labor. Hence, creators and YouTubers accept the exploitation as a fair demand because of process alienation, mystification, reification and naturalization.

Digital literacy of a woman is still a crucial problem, particularly on the social media. Many articles indicate that a woman as a potential audience target of consumption and contribution of information hoax. The goal of this research is to identifying of the affectivities of woman digital literacy on using digital media primarily on social media. Subject of the research is the Indonesian Army’s wives Association (PERSIT) Skadron 31 PUSPENERBAD Semarang. The method that is used in this case is qualitative method to observing and sharpening of information and analysis among resource discoveries. Result of research indicates that the wives of army mostly using social media in gaining information by using social media of gaining information by the way of accessing it with mobile-phone. Respondents use social media to exchanging information, preserving friendship relation, purchasing and marketing on-line, vacation and self-actualization. Socialization and warning are forwarding routinely during the meeting of the association. Regarding digital literacy it gives positive side and the women understand the negative side as well and its consequences of using digital media which is not appropriate, even the impact is not to those concerned but the family and the institution as well. At the PERSIT organization it is still strongly military hierarchy culture such as reprimand from the superior which gives repentance impact to the members that have been proven of misusing the digital media.
Who I am asking about: What the sentence endings imply about the unexpressed subjects in wh-questions
Authors: Izutsu Katsunobu , Kim Yong-Taek
Published: December 2019

This study demonstrates that the sentence endings of Korean and Japanese wh-questions can be analyzed as serving to evoke and, in a weaker sense, to mark an unexpressed verb subject. This study further contends that the endings are not complex forms with successive morphemes each contributing to the whole meaning but rather simplex forms each of which has its own meaning and function. This study argues that pragmatic groupings of event participants help the sentence endings to mark subjects in the Korean and Japanese languages as well as other languages of the world.
Testing Epistemic Injustice
Authors: McCready Elin , Winterstein Grégoire
Published: December 2019

This work builds on the trivial observation that everyone is not trusted equally. One’s gender, ethnic group, occupation etc. will affect how one’s information is believed and interpreted by others. We begin by reviewing past approaches to reliability and epistemic injustice, and the factors which affect how one’s reliability is evaluated by others in discourse. We then discuss recent experimental results which show that the linguistic manipulation of gender seems  to affect the strategies with which the source’s reliability is evaluated. We argue that masculine sources benefit from more charitable assumptions than feminine ones. To support this claim, we present the results of a fine-grained categorization task. The results of this task seem to support our claim about charity, i.e. that a masculine source can more easily claim competence about a topic categorized as feminine, whereas the converse appears less true.
Pneumatologia w eklezjologii Konstytucji Lumen gentium Soboru Watykańskiego II z perspektywy teologii Yves’a Congara
Authors: Kasprzak Artur Antoni
Published: December 2019

For all readers of the text of the Lumen Gentium constitution of the Second Vatican Council during this event, and also immediately afterwards, it seemed that the document focused solely on the explanation of the Church from the perspective of Christ. Some of the conciliar observers, espe- cially the Orthodox theologians, brought up criticism that the reflection of the Council was marked by a Christomonism. This study presents the question of the pneumatological implications of the ecclesiology contained in the Lumen Gentium constitution from the perspective of Yves Congar’s theological thought. As the analysis of the undertaken research will show, the answer of the French theologian not only provides an essential response to the objection of Christomonism based on a direct commitment of this theologian to the co-writing of Lumen Gentium as early as March 1963, but it also gives a thorough insight into the subject-matter referring to his theological achievements already before and mainly after the Council. The Dogmatic Constitution on the Church has a dis- tinct pneumatological dimension. The theology contained therein is related to all the theses on the subject as they were formulated by Yves Congar in 1973.
Wiarygodność Kościoła w dzisiejszej Polsce
Authors: Kaucha Krzysztof
Published: December 2019

There are two purposes of this article: the first one — to clarify the meaning of the term ‘credibility of the Church in contemporary Poland’ from a theological perspective, and the second one — to describe the basic signs of such credibility and the difficulties they are facing. The article consists of three parts and a conclusion. The first part deals with the theological understanding of the Church’s credibility in contemporary Poland in the light of new researches and inspirations offered by Joseph Ratzinger’s ecclesiology and by the book Oblicza Kościoła katolickiego w Polsce. 1050. rocznicaChrztu [Features of the Catholic Church in Poland. The 1050th Anniversary of the Christening] (ed. by J. Mastej, K. Kaucha, P. Borto, Lublin 2016). The second part is focused on the signs of the Church’s credibility in Poland (sign of Peter, of the Apostolic Collegium, of unity, of holiness, of universality, of apostolicity, agapetological, praxeological, martyriological, and culture-creative), which started to be described about 25 years ago by Rev. Marian Rusecki, who was co-founder and the most excellent representative of the Lublin School of Fundamental Theology. The third part presents some new signs of the Church’s credibility in Poland according to the author of the article (charitable, staurological, resurrectional, paschal, anthropological-vocational, of freedom, of the priority of the Spirit and spiritual life, of peace and reconciliation, of protest, of the faith’s pure- ness). In the conclusion the author underlines the values of the semeiological method in describing and testing the credibility of the Church in contemporary Poland.
Otwartość na dar stworzenia
Authors: Moskałyk Jarosław
Published: December 2019

An important duty of man is proper communication and relativity to creation. This is due to the unique situation of our being “in the middle” and our vocation to go out “in the opposite direction”. However, personal faith in God becomes a particularly ennobling factor, as it somehow deepens the human desire for closeness and solidarity with the whole created reality. Through true openness to the visible world, we learn more about the relationship between the individual and the community, as well between the human community and the whole creation. Ultimately, we are trying to take up the challenge of dealing responsibly with nature as a unique value today and with the right to continue in the future.
Zagadnienie „ojczyzny w niebie” w Liście św. Pawła do Filipian i w pismach św. Elżbiety od Trójcy Świętej
Authors: Wilk Janusz
Published: December 2019

The article is a study of the theme of ‘heavenly homeland’ in St. Paul’s Letter to the Philippians3:20 and in the writings of the French Carmelite St. Elisabeth of the Holy Trinity (1880–1906). The first part is an exegesis of Phil 3:20. It consists of a description of the community in Philippi at the time when the Letter to the Philippians was written; suggestion of a translation of Phil 3:17–21 into Polish; general presentation of the context Phil 3:20 and discussion of the meaning of the lexeme politeuma.The second part presents eight writings of Elizabeth of the Holy Trinity (Letters 237; 241; 246; 249; 252; 258; 339; Spiritual Notes [originally Notes intimes] 16), in which she made reference to the thought included in Phil 3:20.The mystic from Dijon, a faithful and eager pupil of Paul the Apostle drew profusely from his inspired thoughts not only for herself but also shared them with others, as evidenced by several references to Phil 3:20 in her writings. Her aim was to strengthen those closest to her (and herself) in following here on Earth the way which would be their common way in eternity.

Battery Monitoring and Control System for Photovoltaic based DC Microgrid
Authors: Chauhan Rajeev Kumar , Chauhan Kalpana
Published: December 2019

This paper presents a battery control and monitoring strategy for a DC microgrid feed by a public utility (PU) photovoltaic (PV) including with multi-battery bank (BB). The BBs respond to the changes in a power imbalance between generation and demand within a DC micro-grid, to maintain the micro-grid voltage and reliability enhancement. The fuzzy model reference learning control (FMRLC) controller has been designed to power control of the battery bank. The proposed battery control and monitoring system (BCMS) strategy keep the battery charging and discharging power as per standard charging/discharging characteristics of the battery. The BCMS allows continuous monitoring and intelligent control of distribution system operations such as battery bank energy storage (BBES), the PV system and the electric load of the consumer. A power sharing between the sources has been controlled for smooth supply. A graphical user interface (GUI) in the MATLAB environment has been configured to demonstrate the control and monitoring of the DC micro-grid and the operation performance of the BCMS algorithm for various scenarios (i. e modes). The proposed BCMS shows better operational performance for various operating conditions in terms of monitoring and control of the batteries power in the grid-connected DC micro-grid.
Becoming BELF users: the learning process of business users of English and its conceptualization
Authors: Takino Miyuki
Published: December 2019

This paper examines the learning process of users of English as a business lingua franca (BELF) from the users’ own perspective and proposes a working model as a framework to understand this process. The discussion is based on a qualitative analysis of interviews of Japanese business people who have been raised and educated in Japan and have used BELF for professional purposes. The interviews explore the linguistic challenges that they have faced in performing their work in English and how they have dealt with these challenges. The prime focus of the discussion in this paper is how BELF users transformed themselves from “learners of English in the classroom” into “BELF users” during the early stage of their professional career. With this focus, I develop a working model of BELF users’ learning process by taking inspiration from the “Experiential Learning Theory” (Kolb 1984.Experiential learning: experience as the source of learning and development. New Jersey: Prentice Hall).Experiential Learning: Experience as The Source of Learning and Development. New Jersey: Prentice Hall), a widely used theoretical model of the learning process of adults, along with other theories in the field of management. The proposed model of BELF users places “learning from experience” of using English at the centre of the development of their English competence, supplemented by “learning from others” and “learning from studying.” This article concludes with pedagogical implications for professional training and higher education and beyond, as well as theoretical contributions to the understanding of English as a lingua franca (ELF)/BELF. By drawing on the detailed stories of Japanese BELF users, I present a dynamic view of the competence of (B)ELF users by considering the significant changes of their competence over time and space throughout their careers rather than a snapshot of their competence at a particular time.

Computational construction grammar for visual question answering
Authors: Nevens Jens , Van Eecke Paul , Beuls Katrien
Published: December 2019

In order to be able to answer a natural language question, a computational system needs three main capabilities. First, the system needs to be able to analyze the question into a structured query, revealing its component parts and how these are combined. Second, it needs to have access to relevant knowledge sources, such as databases, texts or images. Third, it needs to be able to execute the query on these knowledge sources. This paper focuses on the first capability, presenting a novel approach to semantically parsing questions expressed in natural language. The method makes use of a computational construction grammar model for mapping questions onto their executable semantic representations. We demonstrate and evaluate the methodology on the CLEVR visual question answering benchmark task. Our system achieves a 100% accuracy, effectively solving the language understanding part of the benchmark task. Additionally, we demonstrate how this solution can be embedded in a full visual question answering system, in which a question is answered by executing its semantic representation on an image. The main advantages of the approach include (i) its transparent and interpretable properties, (ii) its extensibility, and (iii) the fact that the method does not rely on any annotated training data.
On minimum algebraic connectivity of graphs whose complements are bicyclic
Authors: Liu Jia-Bao , Javaid Muhammad , Raza Mohsin , Saleem Naeem
Published: December 2019

The second smallest eigenvalue of the Laplacian matrix of a graph (network) is called its algebraic connectivity which is used to diagnose Alzheimer’s disease, distinguish the group differences, measure the robustness, construct multiplex model, synchronize the stability, analyze the diffusion processes and find the connectivity of the graphs (networks). A connected graph containing two or three cycles is called a bicyclic graph if its number of edges is equal to its number of vertices plus one. In this paper, firstly the unique graph with a minimum algebraic connectivity is characterized in the class of connected graphs whose complements are bicyclic with exactly three cycles. Then, we find the unique graph of minimum algebraic connectivity in the class of connected graphs
$\begin{array}{}
{\it\Omega}^c_{n}={\it\Omega}^c_{1,n}\cup{\it\Omega}^c_{2,n},
\end{array}$ where
$\begin{array}{}
{\it\Omega}^c_{1,n}
\end{array}$ and
$\begin{array}{}
{\it\Omega}^c_{2,n}
\end{array}$ are classes of the connected graphs in which the complement of each graph of order n is a bicyclic graph with exactly two and three cycles, respectively.
Challenging the Modern Subject in Joseph Conrad’s “The Planter of Malata”
Authors: Sokołowska Katarzyna
Published: December 2019

Conrad’s story “The Planter of Malata,” by focusing on the portrayal of Geoffrey Renouard, addresses the dilemmas of the modern self implicated in the subjectivist mode of experiencing the world. Heidegger’s reinterpretation of the Cartesian ego and his conceptualization of modern subjectivity provide a theoretical framework for clarifying the paradox of Renouard’s position which involves both demonstrations of mastery and gestures of submission in his interactions with Felicia Moorsom. The paper examines how the subject construes the world as representation and reduces the world to the object to be manipulated and controlled. Renouard’s experience of irrational desire and his loss of mastery, which lead to the collapse of the subject/object duality and the dissolution of representation, dismantle the project of the omnipotent ego. Eventually, the breakdown of the ego engenders a growing paralysis of will, enhances the lure of death-like stasis and culminates in Renouard’s suicide.
Comparison of the Hounsfield Unit in CT scan with the Gray Level in cone-beam CT
Authors: Razi Tahmineh , Emamverdizadeh Parya , Nilavar Nadia , Razi Sedigheh
Published: December 2019

Background. The present study was undertaken to compare the Hounsfield Unit (HU) in computed tomography (CT) with the gray level in CBCT in human tissues. Methods. In this study, 25 different soft and hard tissues were evaluated in 21 patients. CBCT images were taken with Newtom VGi machine (Verona, Italy) and CT images were prepared with Somatom Sensation unit (Siemens, Germany). The HU values of soft and hard tissues were compared with the gray level values of CBCT images. Results. There was a strong correlation between the HU in CT and the gray level in CBCT in soft tissues (P<0.001, R2=0.85) and hard tissues (P<0.001, R2=0.74) and in general (P<0.001, R2=0.91). Conclusion. A high degree of agreement was seen between HU in CT and gray level in CBCT in both hard and soft tissues. Since the gray level in CBCT was similar to HU in CT and can be used as a parameter determine bone density in implant treatment and also to determine the bone type, the CBCT technique is recommended in such cases due to its low radiation dose, short time and low cost compared to CT.
Effect of adding TiO2 nanoparticles on the SEM morphology and mechanical properties of conventional heat-cured acrylic resin
Authors: Moslehifard Elnaz , Robati Anaraki Mahmood , Shirkavand Saeed
Published: December 2019

Background. The current study evaluated the compressive, flexural and impact strengths of heat-cured acrylic resins reinforced by TiO2 nanoparticles (NPs). Methods. TiO2 NPs were provided and characterized using scanning electron microscopy (SEM) to determine their morphology and crystalline structure. For three mechanical tests, 12 acrylic resin groups (n=9), totaling 108 specimens, were prepared using a special mold for each test, with TiO2 nanoparticle contents of 0, 0.5, 1 or 2 wt% in different groups. After curing, the compressive, flexural and impact strengths of the specimens were examined according to ISO 1567. Results. In the SEM and XRD study of TiO2 NPs, anatase was identified as the major crystalline phase followed by rutile (average particle size: 20.4 nm). SEM images showed that the nanocomposite with 1 wt% NPs had a more homogenized blend. 1 wt% TiO2 nanocomposite exhibited a higher, but non-significant, impact strength compared to the controls. ANOVA showed significant differences in the impact and flexural strengths between nanocomposites with various contents of TiO2 NPs. Conclusion. The nanocomposite with 1 wt% TiO2 NPs exhibited fewer micro-pores and micro-cracks in the SEM cross-sections. A non-significant increase was also observed in the impact strength with TiO2 NPs at 1 wt%. Further increase in TiO2 NPs decreased both the impact and flexural strengths. The compressive strength of the heat-cured acrylic resin was not affected by the incorporation of NPs.

SNP-CRISPR: A Web Tool for SNP-Specific Genome Editing
Authors: Chen Chiao-Lin , Rodiger Jonathan , Chung Verena , Viswanatha Raghuvir , Mohr Stephanie E , Hu Yanhui , Perrimon Norbert
Published: December 2019

CRISPR-Cas9 is a powerful genome editing technology in which a single guide RNA (sgRNA) confers target site specificity to achieve Cas9-mediated genome editing. Numerous sgRNA design tools have been developed based on reference genomes for humans and model organisms. However, existing resources are not optimal as genetic mutations or single nucleotide polymorphisms (SNPs) within the targeting region affect the efficiency of CRISPR-based approaches by interfering with guide-target complementarity. To facilitate identification of sgRNAs (1) in non-reference genomes, (2) across varying genetic backgrounds, or (3) for specific targeting of SNP-containing alleles, for example, disease relevant mutations, we developed a web tool, SNP-CRISPR (https://www.flyrnai.org/tools/snp_crispr/). SNP-CRISPR can be used to design sgRNAs based on public variant data sets or user-identified variants. In addition, the tool computes efficiency and specificity scores for sgRNA designs targeting both the variant and the reference. Moreover, SNP-CRISPR provides the option to upload multiple SNPs and target single or multiple nearby base changes simultaneously with a single sgRNA design. Given these capabilities, SNP-CRISPR has a wide range of potential research applications in model systems and for design of sgRNAs for disease-associated variant correction.
Genetic Paths to Evolutionary Rescue and the Distribution of Fitness Effects Along Them
Authors: Osmond Matthew M , Otto Sarah P , Martin Guillaume
Published: December 2019

Novel environments can cause strong selection and rapid adaptation. The genetic basis of such rapid adaptation tends to be composed of few loci of large effect. Current theory qualitatively agrees but largely neglects the demographic...

The past century has seen substantial theoretical and empirical progress on the genetic basis of adaptation. Over this same period, a pressing need to prevent the evolution of drug resistance has uncovered much about the potential genetic basis of persistence in declining populations. However, we have little theory to predict and generalize how persistence—by sufficiently rapid adaptation—might be realized in this explicitly demographic scenario. Here, we use Fisher’s geometric model with absolute fitness to begin a line of theoretical inquiry into the genetic basis of evolutionary rescue, focusing here on asexual populations that adapt through de novo mutations. We show how the dominant genetic path to rescue switches from a single mutation to multiple as mutation rates and the severity of the environmental change increase. In multi-step rescue, intermediate genotypes that themselves go extinct provide a “springboard” to rescue genotypes. Comparing to a scenario where persistence is assured, our approach allows us to quantify how a race between evolution and extinction leads to a genetic basis of adaptation that is composed of fewer loci of larger effect. We hope this work brings awareness to the impact of demography on the genetic basis of adaptation.

Background and aim. Dental erosion (DE) represents a frequent condition in adults and the elderly. The gastroesophageal reflux disease (GERD) is considered an important endogenous factor causing dental erosions. The objective of this study was to assess the prevalence of DE in GERD patients and to establish the correlation between pathogenic intrinsic and extrinsic factors of DE and their relation to GERD.

Methods. A cross-sectional study was conducted on 263 patients (median age 43). Patients with heartburn were recruited in two countries with different prevalence of GERD. Patients were recruited from France (n=158, 60%) and Romania (n=105, 40%) including 163 females and 100 males. The Basic Erosive Wear Examination (BEWE) index for diagnosis and evaluation of dental erosion was used. Based on the value of BEWE score, each patient was included in a risk group for DE development (low risk: BEWE=3-8, medium risk: BEWE=9-13, high risk: BEWE ≥14). Patients filled a questionnaire regarding GERD symptoms, medications, life style. Salivary parameters (pH and buffering capacity) were also assessed and analyzed.

Results. DE was significantly more frequent and more severe in GERD subjects than in the non-GERD controls. Low salivary pH but not salivary buffering capacity was associated with BEWE scores. Buffering capacity however was significantly more altered in patients with BEWE score over 9 (medium DE) than in patients with mild DE (BEWE <9). Although extrinsic factors (consumption of citrus fruits, soda drinks) were associated with DE in GERD, there was no statistical correlation with the BEWE score. From the total of 263 patients, 229 (87.1%) presented BEWE score <9, and 34 (12.9%) presented BEWE ≥9. The DE was significantly associated with the presence of GERD (p<0.001). BEWE score >9 was more frequently present in GERD patients (30 patients: 21.3%) than in non GERD patients (4 patients: 3.3%). DE were more frequent in French subjects compared to Romanian subjects. Romanians had lower BEWE scores than the French.

Conclusions. DE is more frequent and more severe with GERD vs. non-GERD. DE in GERD is associated with extrinsic dietary factors like citrus fruits and soda drinks.

ABSTRAKKegiatan PLTU berpotensi menghasilkan logam merkuri (Hg) yang bersumber dari batubara sebagai bahan bakunya. Merkuri memiliki sifat yang presistent  dan mampu mengalami bioakumulasi dan biomagnifikasi dalam rantai makanan. Kegiatan PLTU di Palabuanratu akan beroperasi selama 20 tahun dan hal ini menimbulkan kekhawatiran merkuri yang dihasilkan akan mencemari air laut dan masuk dalam rantai makanan di perairan Teluk Palabuhanratu. Tujuan pemodelan ini adalah melakukan prediksi dan menganalisa faktor dominan dari peningkatan Merkuri air laut selama masa beroperasi PLTU serta terjadinya biomagnifikasi dalam rantai makanan. Gambaran mengenai jejak merkuri dari sumber batubara PLTU di udara, air dan rantai makanan, kaitannya dengan peningkatan konsentrasi merkuri di perairan menggunakan metode System dynamics. Hasil pemodelan menunjukan peningkatan Merkuri akan melebihi baku mutu Keputusan Menteri Lingkungan Hidup no. 51 Tahun 2004 untuk biota laut pada Tahun 2027. Terjadinya biomagnifikasi kepada ikan plankton feeder, ikan top predator dan kepada manusia mulai tahun 2017 dimana konsentrasi metil merkuri (MeHg) pada manusia sebagai konsumen tertinggi lebih besar dibanding pada ikan top predator dan Ikan Plankton feeder, namun masih di bawah level ketiganya level toleransi MeHg menurut UNEP. Faktor yang dominan meningkatkan Merkuri anorganik dalam air laut adalah ceceran batubara.Kata kunci : Mekuri, Batubara, Biomagnifikasi, Sistem Dinamis

O recurso à sensualidade como estratégia do mercado Gospel
Authors: De Souza Sandra Duarte , Da Silva João Marcos
Published: December 2019

Resumo: Este artigo tem como objetivo analisar o uso do erotismo e da sedução como parte da estratégia de marketing presente nas produções dos “artistas” gospel a partir da década de 1990. Na sociedade de consumo ocidental, o uso da imagem carrega uma carga considerável de exploração de sua corporeidade. Neste sentido, a sensualidade e a erotização visual tornam-se componentes presentes nas artes comerciais publicitárias atuando como atrativo pelo viés do desejo, transformando o corpo num híbrido na qual corpo e produto se misturam. Desta forma, o texto disserta sobre a relação paradoxal do corpo na teologia clássica cristã, no protestantismo e na contemporaneidade através do cenário gospel, demonstrando o processo de traslado e apropriação dentro da cultura visual evangélica, da lógica de mercado secular e consequentemente do uso da sedução como instrumental do marketing religioso.
Las aplicaciones tecnológicas al servicio de la educación superior
Authors: Gomez Quitian Juan Carlos
Published: December 2019

El presente artículo muestra como las aplicaciones tecnológicas se han convertido en una herramienta educativa para el fortalecimiento de los procesos educativos y pedagógicos en la Universidad Católica de Colombia. Para ello se realizó una investigación descriptiva, la cual pretendió referir o narrar características y propiedades de un objeto, sujeto o situación específica, sin emplear juicios de valor y en procura de objetividad, y desde el enfoque cualitativo, partiendo de que este permite dar cuenta de un proceso activo, sistemático y riguroso de indagación dirigida, con el fin de conocer el objetivo de algunas aplicaciones tecnológicas al servicio de la educación.  El trabajo de campo se realizó con estudiantes (hombres y mujeres) matriculados en las asignaturas del departamento de humanidades de la Universidad Católica de Colombia, que son estudiantes de diversos semestres y facultades y han sido iniciadores en este proceso educativo–pedagógico junto a las aplicaciones tecnológicas (Página Wix, Códigos QR, Kahoot y Pixtón) para el desarrollo y profundización de la temática, como un apoyo al proceso de aprendizaje de los estudiantes por medio del juego. El resultado muestra que existe en los estudiantes un proceso pedagógico de invisibilización frente a las nuevas tecnologías, con sus características y avances hacia un mejor desempeño en los procesos académicos de educación superior, es así que el gran reto hoy es educar y formar a los estudiantes junto con las herramientas tecnológicas que los acompañan en su cotidianidad, que las llevan en sus venas, es decir, son su vida.
Role of higher education in Colombia in peacebuilding
Authors: Delgado-Albán Darling Viviana
Published: December 2019

This is a reflection that attempts to analyze the role of universities in Colombia during the peacebuilding process. It is necessary to state out the relevant practices that the educational community has been used to empower education during war times. Moreover, it is critical to understand several facts that Colombian higher education has faced during the conflict and the post-conflict. The circumstances that the education in Colombian has been exposed to is just a sign that interventions and improvements are necessary to achieve a sustainable peace were minorities, students who have been victims of the conflict, and individuals that need support through education opportunities need to be a priority. It is important to know how instructional practices have become key tools that contribute to peacebuilding by the teaching of moral values, principles, concepts about the importance of the family, knowledge about good aspects of citizenship, and culture, and leadership strategies which enhance learners’ attitudes towards becoming citizens able to build a strong society that guarantees a positive future to its generations. This article shows that peace education is an essential element in achieving a sustainable peace around Colombia, where thousands of learners have been affected by the war that has frustrated their dreams and has hypnotized their hopes of living in a secure country where the possibilities to achieve a successful future turn each time further. This reflection is a resource for students and teachers to dig in their daily practices and interiorize the manners in which they can contribute positively to peacebuilding from the academy.

Authors: DENİZ Nurcan , BÜYÜK Köksal
Published: December 2019

Quality is a high
priority topic in healthcare services. After the debates on the implementation of
SERVQUAL, the most widely used generic scale to determine service quality, in
the healthcare industry, recent studies on service quality focus on the
development of industry and culture-specific scales. The initial aim of this
study is to develop a model for the conceptualization of healthcare service
quality, and then develop a valid and reliable scale that can be used in the
measurement of the perceived healthcare service quality of inpatients in
Turkish public hospitals through exploratory and confirmatory factor analyses. The
study also recommends a method to be used in the model for the prioritization
of dimensions. The devised scale was implemented on 268 patients in a public
hospital in Eskisehir, Turkey. The output shows that the inpatients rank
quality dimensions based on their priorities as staff quality, physical quality
and process quality respectively. A 51-item scale has been recommended, as a result
of statistical analyses

FORMATION OF SPINEL STRUCTURE IN SYNTHESIS PROCESS OF Li1.37Mn2O4 USING HYDROTHERMAL METHOD. Li1.37Mn2O4 is one form of Li1+xMn2O4 which is engineered from LiMn2O4 phase which is commonly used as a lithium cathode active ingredient. The crucial thing from Li1.37Mn2O4 synthesis is the spinel structure that is formed. This study aims to observe when the spinel structure of Li1.37Mn2O4 starts and when the transformation from a tetragonal structure into spinel occurs. The raw materials used are tetragonal LiOH and tetragonal MnO2. The synthesis was carried out using a hydrothermal method with a temperature of 200 oC with a variation of holding times of 50, 70, 90 and 110 hours. Observation of spinel structure was carried out using XRD and TEM. The results obtained were at the holding times of 50 and 70 hours, the spinel structure had not been formed. The spinel structure begins to form at 90 hours holding time which also indicates that the transformation from the tetragonal structure to spinel occurs at such holding time. The result of a 90-hour holding time is a regular spinel structure but there are still many Mn and Mn-O –based impurities. While the results of the 110-hour holding time produce a perfect yet irregular transformation of the spinel structure.

APPLICATION OF SULFONATED POLYSTYRENE IN POLYMER ELECTROLYTE FUEL CELL. Sulfonated polystyrene (SPS) is polyelectrolyte solid that widely used in many aplications. In this works SPS is applied for some parts of polymer electrolyte fuel cell membrane due sulfonate group available in the structure. The investigation involve the application for membrane with addition of small molecules, i.e. benzimidazole and evaluating its microstructure and performance. Application of SPS solution as binding agent in MEA will also be presented.  The results show that when using SPS as fuel cell membrane, the additon of small molecules such as benzimidazole would modify its microstrusture as well as improve its ion conductivity. Meanwhile, some improvement still required for application of SPS solution as binding agent for preparation of Membrane Electrode Assembly or MEA.
