Authors: Голубева Елена , Golubeva Elena , Истратова Оксана , Istratova Oksana
Published: February 2018

The monograph considers the type of disharmonic parental attitude to the child – his emotional rejection. Against the background of numerous studies of a dysfunctional family and its impact on the development and socialization of the child, emotional rejection is common in externally prosperous families, which is a hidden risk factor for distortion of the child's development and social adaptation.
The book presents an analysis of modern domestic and foreign research positions on the causes and consequences of emotional rejection of a child in the family. On the basis of the selected psychological characteristics of modern children and adolescents analyzed the results of a number of empirical studies of their personal development in the context of emotional rejection in the family. The book presents practical tools for the organization of diagnostic and correctional and developmental work with children and their parents

Published: February 2018

BACKGROUND

Numeracy, health literacy, and cognition are important for chronic disease management. Prior studies have found them to be associated with poorer self‐care and worse clinical outcomes, but limited data exists in the context of heart failure (HF), a condition that requires patients to monitor their weight, fluid intake, and dietary salt, especially in the posthospitalization period.

OBJECTIVE

To examine the relationship between numeracy, health literacy, and cognition with 30‐day readmissions among patients hospitalized for acute decompensated HF (ADHF).

DESIGN/SETTING/PATIENTS

The Vanderbilt Inpatient Cohort Study is a prospective longitudinal study of adults hospitalized with acute coronary syndromes and/or ADHF. We studied 883 adults hospitalized with ADHF.

MEASUREMENTS

During their hospitalization, a baseline interview was performed in which demographic characteristics, numeracy, health literacy, and cognition were assessed. Through chart review, clinical characteristics were determined. The outcome of interest was 30‐day readmission to any acute care hospital. To examine the association between numeracy, health literacy, cognition, and 30‐day readmissions, multivariable Poisson (log‐linear) regression was used.

RESULTS

Of the 883 patients admitted for ADHF, 23.8% (n = 210) were readmitted within 30 days; 33.9% of the study population had inadequate numeracy skills, 24.6% had inadequate/marginal literacy skills, and 53% had any cognitive impairment. Numeracy and cognition were not associated with 30‐day readmissions. Though (objective) health literacy was associated with 30‐day readmissions in unadjusted analyses, it was not in adjusted analyses.

CONCLUSIONS

Numeracy, health literacy, and cognition were not associated with 30‐day readmission among this sample of patients hospitalized with ADHF.

The Effect of Learning Cycle Models on Achievement of Students: A Meta-Analysis Study
Authors: Sarac Hakan
Published: February 2018

In the study, a meta-analysis was conducted to determine the effect of the use of the learning cycle model on the achievements of the students. Doctorate and master theses, made between 2007 and 2016, were searched using the keywords in Turkish and English. As a result of the screening, a total of 123 dissertations, which used learning cycle models to increase the achievement of students, were included in the analysis. As a result of this study, it is confirmed that the effect of learning cycle models on students’ achievement is positive and the determined effect size was found out as 1.164 (% 95 CI, SE = .071) according to random effects model.. In the study, moderator analysis was made according to the learning cycle models, type of the dissertations, disciplines, and education levels of students. The analyses showed that among the learning cycle models, the highest effect size was determined in the 4E Model (2.659), among the dissertations the highest effect size was in master thesis (ES = 1.231), among the disciplines the highest effect size was in the other lessons (ES = 1.637) and among the educational levels the highest effect size was in the high school students (ES = 1.237).
Learning a Language and Studying Content in an Additional Language: Student Opinions
Authors: Ger Ugur , Bahar Mustafa
Published: February 2018

This study aims to understand the opinions of middle school and high school students about language learning and studying other content in an additional language in the school settings where English is used as the medium of instruction to teach more than 50% of the curriculum. For this end, 261 students from three different schools were administered a questionnaire.  Results indicate students generally have very positive opinions about learning languages and studying content in their non-native language. There is no statistically significant difference between the students’ opinion and their school level, and the years that they have been learning a language and studying content in an additional language. However, the students who have a negative opinion about the school have negative opinions about learning languages and studying content in an additional language. The possible reasons for these were evaluated from the perspective of language learning context but further study would be needed to establish causality.

Executar é preciso, planejar não é preciso: proposta de framework para projetos de pesquisa
Authors: Lukosevicius Alessandro Prudêncio
Published: February 2018

A qualidade do projeto de pesquisa influencia o rigor teórico-metodológico e a contribuição de valor do trabalho científico produzido. O design inadequado e a falta de maturação dos projetos de pesquisa são alguns dos problemas que mais levam à rejeição direta de artigos, mormente, nas áreas de administração, contabilidade e turismo. Mas, apesar da importância, muitas vezes, essa etapa é negligenciada e tratada de forma descuidada. Por isso, este artigo propôs-se a uma abordagem gráfica para projetos de pesquisa que pode auxiliar pesquisadores, sobretudo, iniciantes, a planejarem suas pesquisas. Para cumprir tal objetivo, conjugou-se revisão da literatura com análise de conteúdo, tendo por referência artigos e livros da área metodológica. Como resultado, desenvolveu-se o Research Project Model Canvas (RPMC), um framework que provê direcionamento ao pesquisador, auxiliando-o a evitar erros, mas sem lhe suprimir a criatividade e o espaço da tomada de decisão.

Pedagogies and practices of disaffection: Film programmes in arts schools in a time of revolution
Authors: Mistry Jyoti , Andrew David
Published: February 2018

This article offers a set of interrogative questions about the role of arts schools at the time of political change. It is significant for institutions on the African continent and in the global South to create an interventionist space that might provide an enabling environment that is both reflective and reflexive of knowledge production. By potentially positioning artistic research as a mode of pedagogy and practice (in the arts school generally) and by recognizing its implications for film programmes, this article sets out to scrutinize the changing role of the arts school. The focus in this article is on the general historical relationship between arts schools and film schools as institutional frameworks where specific pedagogic practices take place. More specifically, this scrutinization of the arts school in the global South takes place from the vantage point of Johannesburg, South Africa with a view of expressing the potential of artistic research as a potentially decolonizing approach to curriculum transformation.
Point of view: Engaging with history and memory in the classroom
Authors: Sakota Tanja
Published: February 2018

South Africa’s turbulent past has led to its history being rewritten a number of times. The events of the last 450 years in particular have had a huge impact on the social, political and historical context, resulting in the current social tropes and inequalities emerging frequently as topics for discussion in the classroom. In April 2015 students at the University of Cape Town embarked on the RhodesMustFall campaign. The spirit of the campaign spread quickly across the country as students and citizens embarked on heated debates and protests on the significance and memory of such monuments. In the classroom students were encouraged to rethink monument spaces and interrogate the politics of remembering within the context of film studies. The theoretical framework focused on Marita Sturken’s premise that history, culture and memory are immersed in cultural artefacts that play a significant role in how we understand the past and its relationship with the present and the future. This article will discuss key theoretical ideas that emerged through interactions with students with reference to the RhodesMustFall campaign and how the cinematic space acts as a platform to rethink monument spaces.
Redirecting the gaze: Film education in an individualistic era
Authors: Sternö Linda , Björk Klara
Published: February 2018

This article offers consideration to an alternative use of film practice and the role of pedagogy in challenging the conception of film as a product and entertainment medium. Instead the authors reflect on the potential of the camera as a tool for facilitating dialogue with communities and individuals, which allows student filmmakers to draw on images and representations that challenge the stereotyped and repetitive images generated in mass media. Furthermore, they draw from their own experiences of working with the visual practice (VP) model where the camera is a research tool. As a tool, the camera is used to explore issues in contemporary society and is related to contextual responsibilities and concerns regarding film pedagogy and its connection to enabling social change, with a broader correlation to civil society that aims to promote democratic rights.
Learning, growing and making films in a diverse setting: Collaboration and reflection in a community-engagement video training programme
Authors: Maasdorp Liani
Published: February 2018

Stepping Stone community-engagement video training was launched in 2012 to open University of Cape Town film and media facilities, equipment and knowledge to a wider audience, linking university with non-university communities, and creating opportunities for creative collaboration and social interaction between diverse participants. The current curriculum and approach are the result of ongoing action research aimed at evolving the programme based on observation and reflection to best serve the diverse group of participants. One of the course assignments challenges participants to identify original concepts about their geographical communities and communities of interest, and generate content that will appeal to niche audiences that they are uniquely positioned to access. Another provides opportunities for in-service learning in a supportive environment. The aim of this article is to reflect on the ongoing design, implementation and impact of the project by asking: What strategies have been used to inform the design the course? Have they fostered an environment conducive to creative collaboration between diverse participants? And what impact has this had on the participants and their potential to work in the South African film and television industries?
The changing cinema spaces of Accra: Fragmented spectatorship and the loss of empathy
Authors: Nåls Jan
Published: February 2018

Cinema theatres are designed to foster collective emotional responses. Ghana’s capital Accra, like many other African cities, used to be full of such spaces. Urban infrastructures no longer support cinema theatres, and subsequently, television, video and small screens, in general, have replaced the dark room. This study explores some key aspects of how film spectatorship is embedded in the historical and current geography of Accra. It traces the undoing of cinema and its spaces, as well as the possible consequences of this development. The article retells an artistic research process that took place in a video parlour in Accra. The findings of the artistic research are supported in part by theories on space and apparatus. In Accra, collective spectatorship has turned into a mostly random event. Passers-by watch short glimpses of narratives without a pre-existing understanding of, nor commitment to, the narrative. Fragmented spectatorship can ultimately lead to a loss of shared feeling – empathy – between audience members and film characters, and as a consequence, between members of broader societal and even global contexts.
Practice-led research: Home video and the autobiographical self
Authors: Comninos Nikki
Published: February 2018

This article explores the place of personal testimony against broader political landscapes of official histories and narratives. It looks at family archive as a curated record of the autobiographical self and the enduring political value of the everyday. I reflect on my creative arts Ph.D. where I made a documentary exploring personal history and memory. The film, comprised predominantly of my own home video footage, is set against the backdrop of the political situation in Southern Africa during the 1980s and 1990s, when my twin brother and I were born in Zimbabwe and then returned to South Africa after the unbanning of the African National Congress. Home video is employed as a methodological instrument to explore a theoretical landscape where I have located my mode of practice as an autoethnographic. This article analyses how the film provided an objective anchor for my deeply personal entry into filmmaking and academia.
Thinking through the visual: Cinematic practice as a productive site of epistemic inversion
Authors: Mntambo Nduka
Published: February 2018

This article considers ways in which multiple expressions and interpretations of Johannesburg can best be understood when processes at the fringes are articulated through creative/artistic practices. Often these expressions are in languages or forms that seek to challenge dominant or pre-determined forms and give rise to modalities that are determined from within the (artistic) communities that occupy fringe spaces. This article suggests that the methods of artistic research enquiries are viable modes to read three contemporary South African films – Driving with Fanon (Mokwena, 2005), Conversations on a Sunday Afternoon (Matabane, 2005) and I Mike what I Like (Mistry, 2006). It further investigates how the forms of these films write an alternative vocabulary of selected African cities, which might be expressed rather than simply represented. Following Sarat Maharaj’s idea of visual art as knowledge production, this discussion considers these film case studies as epistemic engines/contraptions and explicates the attended questions of artistic research as a mode of enquiry. Second, in reading the formal and discursive moves offered in these films, this analytical description mobilizes Achille Mbembe’s modes of self-writing in order to develop techniques of reading and writing that are characterized by aesthetic openings and encounters, a kind of reading and writing characterized by intersecting encounters between diverse fields of knowledge(s) and epitomes. Finally, the analysis tentatively locates artistic practices in the case studies within the broader frame of the decolonial, suggesting that the representational strategies present in the film case studies can be read as entry points in conversing with Eve Tuck and Wayne Yang’s question of thinking about what decolonization means, what it wants and requires.
Mama Jack and the Spectre of makwerekwere
Authors: Tagwirei Cuthbeth
Published: February 2018

This article looks at the ways in which Mama Jack, a South African slapstick comedy, frames certain individuals and groups as makwerekwere. The term, which is popularly used in reference to African migrants in South Africa, appears in the film despite the absence of any African migrant in the literal sense. Nonetheless, Leon Schuster, who plays the lead roles in the film, provides the conditions of the term’s use by performing blackness and exhibiting a stock of images associated with black foreignness. Makwerekwere therefore signifies a phony presence and serves to visualize violence against black foreigners. The article develops from the understanding that all texts, film included, communicate specific ways of seeing the world and therefore participates in the construction and circulation of normalized and misrecognized forms of violence. Film’s signifying potential need not be understated. By focusing on the various ways in which makwerekwere are deployed in Mama Jack, it will be noted that the pursuit of the comic tends to obfuscate and validate the negative portrayal of black foreigners.
The representation of African womanhood in Sembene’s Moolaade: An Africana womanist reading
Authors: Chikafa-Chipiro Rosemary
Published: February 2018

In Moolaade, Sembene engages the subject of female circumcision (excision). Female circumcision has generated several debates in many circles within and beyond the borders of Africa. Feminists and other activists consider it a violation of human rights and an extreme form of women oppression. On the other hand, its practitioners consider it a rite of passage and a procedure of purification. In many of the debates, the image of African womanhood is subjected to a pornotropic gaze. Pornotroping, as explained by Tamura Lomax, refers to the ‘othering’ of black women and girl’s bodies that occurs through the production, reproduction, circulation and maintenance of myths, superimposed on these bodies through signs, symbols, significations and representations. This article seeks to utilize an Africana womanist reading in examining how Sembene represents the identities and subjectivities of African womanhood within the circumcision debate in Moolaade. The article questions whether Sembene subscribes to or subverts pornotropia in his representation of African womanhood and the larger female circumcision debate in Moolaade.
Surviving the impossible: The function of magical realism in Teresa Prata’s Terra Sonâmbula
Authors: Mulliken Douglas
Published: February 2018

Teresa Prata’s film Terra Sonâmbula (2007), an adaptation of Mia Couto’s magical realist novel of the same name, examines violence from a different perspective than its source material – although both the novel and the film consider the difficulties confronting Mozambican society in the face of a horrific civil war, Couto’s novel was published the same year the war ended, while Prata’s film was released fifteen years later, with the national climate much altered. Despite this difference, both the novel and the film make use of magical realism in certain pivotal moments of their narratives. This study analyses the function of magical realism in both works, arguing that the concept serves as a sort of coping mechanism, a way of making sense of the world that allows the narratives’ characters to remain hopeful despite the violence and devastation that surrounds them.
Waywardness of mood and mode in Love the One You Love and Necktie Youth
Authors: Strauss Helene
Published: February 2018

At a time when the reconciliation narratives peddled during the Mandela and Mbeki eras are increasingly coming under stress, a number of South African filmmakers have been offering viewers deeply felt, often autobiographically inflected and experimental filmic engagements with the everyday, affective textures of contemporary political disillusionment. This article reads two films associated with the so-called ‘New Wave’ in South African filmmaking – namely Jenna Cato Bass’s Love the One You Love (2014) and Sibs Shongwe-La Mer’s Necktie Youth (2015) – in order to map the contours of waywardness as a mood and mode of cinematic narration peculiar to a particular post-transitional South African political conjuncture. Inspired by a recent flurry of international scholarly activity on the topic of mood, my analysis of these films considers the nuances that a reading of mood bring to understanding the aesthetics of ‘wayward feeling’ in contemporary South African visual culture.

Possibilities for queer revolution in Glauber Rocha’s Barravento/The Turning Wind (1962)
Authors: Hodgson James
Published: February 2018

Previous readings of Glauber Rocha’s Barravento/The Turning Wind (1962) have generally focused on Marxist rhetoric or on the film’s treatment of Candomblé. Through a close reading of the film, this article proposes an interpretation that foregrounds the film’s depiction of sexuality and sexual identity, which helps illuminate to a greater degree the film’s potential to challenge the status quo. Coupling a queer theoretical framework with attention to the specificities of contemporary Brazilian sexual culture, this article suggests that the film’s more ambivalent or contradictory aspects often relate to how it constructs sexuality and sexual identity. Furthermore, it suggests that tensions around sexual identity can be traced to the heart of the political problem Rocha explores in Barravento, and that the resolution of these tensions is key to the development of a liberated, non-hierarchical and anti-authoritarian community.
National history, allegory and the force of habit in the films of Matías Piñeiro
Authors: Lanctot Brendan
Published: February 2018

This article examines how Matías Piñeiro’s films El hombre robado/The Stolen Man (2007) and Todos mienten/They all Lie (2009) critically redeploy foundational figures and rhetorical devices that structure the dominant narratives of Argentine national history. Both films take lesser-known writings of the nineteenthcentury intellectual and statesman Domingo Faustino Sarmiento, best known for Facundo: Civilización y barbarie/Facundo: Civilization and Barbarism (1845) (1845), as the point of departure for intricate plots involving the romantic intrigues of young people in twenty-first century Buenos Aires. Contrary to the teleology integral to official versions of national history, which have been conspicuously on display during the Bicentennial celebrations of Latin American independence in recent years, Piñeiro’s films posit a more porous and more unstable relationship between the present and history, in which the ruins of the latter persistently, if intermittently, and fragmentarily inform everyday life, and vice versa. Thus, through the insistent repetition of the basic components of foundational myths of Argentine identity, El hombre robado and Todos mienten redirect a force of habit to restore the polysemy of the commonplace tropes of national history.
Tracing borderscapes in three recent documentaries on Central American migration
Authors: Vanhaelemeesch Jasper
Published: February 2018

This article looks at visual configurations of border landscapes and Central American migrant trajectories in three recent documentaries: Which Way Home (Cammisa, 2009), De Nadie/No One (Dirdamal, 2005) and Who is Dayani Cristal? (Silver and García Bernal, 2013). It examines elements pertaining to the representations of borders, space and identity to expand Shaw’s classification of the new sub-genre of migration films within the documentary. It also highlights the social configuration of space because of its relational construction and its production through practices of material engagement: ‘if time unfolds as change then space unfolds as interaction’. To this end, the spatial metaphor of the paratopia designates a negotiation of material and human relationality away from essentialist place/non-place thinking. This additionally leads to an examination of the migrant body as a depoliticized subject of which the visualization counters the stereotypical discourse of the migrant as a delinquent.
La figuración del niño en el cortometraje documental social y político argentino de los años sesenta y setenta
Authors: Cossalter Javier
Published: February 2018

This article examines a small corpus of Argentine documentaries from the 1950s–70s to analyze the role of the representation of children. The inclusion of the voices of the subjects featured, the observational function of the camera and the framing, the spontaneity of the gaze and the use of montage (appropriated from foreign films) came together in this period in these documentary shorts. Thanks to their brief duration, the effectivity of their relationship with spectators and the aesthetic freedom from economic constraints, these documentary shorts became the principal communicative tool for efforts to transform society. The aesthetic figuration of children worked hand in hand with larger political objectives given its ability to move spectators and lead them to reflection, as well as promoting the renovation of domestic filmmaking.

Este artículo examina un corpus de cortometrajes documentales argentinos entre finales de la década del cincuenta y mediados de los años setenta para analizar el rol de la figura del niño en la imagen cinematográfica. La inclusión de las voces de los sujetos retratados, la funcionalidad observacional de la cámara y el encuadre, la espontaneidad de la mirada y el uso marcado del montaje (procedimientos reapropiados de corrientes fílmicas foráneas) hicieron su eclosión en el corto documental local de este período. Gracias a la breve duración, la efectividad en la relación con el receptor, la marginalidad y la libertad estética que deriva de la ausencia de trabas económicas, el cortometraje se convirtió en la principal herramienta de comunicación y transformación de la realidad, en favor de los sujetos y actores sociales marginados. La figuración estética del niño colaboró con los objetivos políticos estipulados mediante la capacidad de sensibilizar al receptor y convocarlo a la reflexión, al tiempo que participó de la modernización fílmica local.
A 100% Renewable Energy Scenario for the Java-Bali Grid
Authors: Guenther Matthias
Published: February 2018

Currently, many countries try to satisfy their energy needs with an increasing usage of renewable resources. The general motivations, with varying weighting in the different countries, are ecological reasons, concerns about energy security, and economical considerations. A for now rather theoretical question, although interesting for opening a long-term perspective, is how an energy supply from exclusively renewable energy resources could look like. This question has to be answered individually for any specific energy supply system. The present paper has the objective to present and evaluate a scenario for an electricity supply only from renewable energy resources for the Java-Bali grid. After designing a load time series for the year 2050 for the Java-Bali grid, a scenario is developed how to cover the load with electricity from renewable energy resources alone. Assumptions about the usable energy sources are made as well as assumptions about the available power plant capacity or energy potential. A specific challenge is the fact that solar energy must be the main source in such a renewable-energy based system, which comes with the need for a large storage capacity to match the power supply at any time with the load. Several possibilities are presented how to bring down the storage capacity: the increment of the installed PV capacity, the usage of bioenergy for seasonal balancing, and the complementation of the proposed short-term storage with an additional long-term storage. The study shows some of the specific challenges that a gradual transformation of the current electricity supply system on Java and Bali into a renewable-energy-based one would face and gives some hints about how to cope with these challenges. Scenarios like the one designed in this study are an important tool for decision-makers who face the task to scrutinize the consequences of choosing between different development paths. Article History: Received: August 15th 2017; Received: October 18th 2017; Accepted: January 14th 2018; Available onlineHow to Cite This Article: Günther, M., Ganal, I. and Bofinger, S.

2D Numerical Simulation and Sensitive Analysis of H-Darrieus Wind Turbine
Authors: Saryazdi Seyed Mohammad E. , Boroushaki Mehrdad
Published: February 2018

Recently, a lot of attention has been devoted to the use of Darrieus wind turbines in urban areas. The aerodynamics of a Darrieus turbine are very complex due to dynamic stall and changing forces on the turbine triggered by changing horizontal angles. In this study, the aerodynamics of H-rotor vertical axis wind turbine (VAWT) has been studied using computational fluid dynamics via two different turbulence models. Shear stress transport (SST) k-ω turbulence model was used to simulate a 2D unsteady model of the H-Darrieus turbine. In order to complete this simulation, sensitivity analysis of the effective turbine parameters such as solidity factor, airfoil shape, wind velocity and shaft diameter were done. To simulate the flow through the turbine, a 2D simplified computational domain has been generated. Then fine mesh for each case consisting of different turbulence models and dimensions has been generated. Each mesh in this simulation dependent on effective parameters consisted of domain size, mesh quality, time step and total revolution. The sliding mesh method was applied to evaluate the unsteady interaction between the stationary and rotating components. Previous works just simulated turbine, while in our study sensitivity analysis of effective parameters was done. The simulation results closely match the experimental data, providing an efficient and reliable foundation to study wind turbine aerodynamics. This also demonstrates computing the best value of the effective parameter. The sensitivity analysis revealed best value of the effective parameter that could be used in the process of designing turbine. This work provides the first step in developing an accurate 3D aerodynamic modeling of Darrieus wind turbines.Article History: Received :August 19th 2017; Received: December 15th 2017; Accepted: Januari 14th 2018; Available onlineHow to Cite This Article: Saryazdi, S.

Automatic and Online Detection of Rotor Fault State
Authors: Ouanas Ali , Medoued Ammar , Haddad Salim , Mordjaoui Mourad , Sayad D.
Published: February 2018

In this work, we propose a new and simple method to insure an online and automatic detection of faults that affect induction motor rotors. Induction motors now occupy an important place in the industrial environment and cover an extremely wide range of applications. They require a system installation that monitors the motor state to suit the operating conditions for a given application. The proposed method is based on the consideration of the spectrum of the single-phase stator current envelope as input of the detection algorithm. The characteristics related to the broken bar fault in the frequency domain extracted from the Hilbert Transform is used to estimate the fault severity for different load levels through classification tools. The frequency analysis of the envelope gives the frequency component and the associated amplitude which define the existence of the fault. The clustering of the indicator is chosen in a two-dimensional space by the fuzzy c mean clustering to find the center of each class. The distance criterion, the K-Nearest Neighbor (KNN) algorithm and the neural networks are used to determine the fault type. This method is validated on a 5.5-kW induction motor test bench.Article History: Received July 16th 2017; Received: October 5th 2017; Accepted: Januari 6th 2018; Available onlineHow to Cite This Article: Ouanas, A., Medoued, A., Haddad, S., Mordjaoui, M., and Sayad, D.

Published: February 2018

The aim of this study is modeling a solar-air heater humidification-dehumidification unit with applying particle swarm optimization to find out  the maximum gained output ratio with respect to the mass flow rate of water and air entering humidifier, mass flow rate of cooling water entering dehumidifier, width and length of solar air heater and terminal temperature difference (TTD) of dehumidifier representing temperature difference of inlet cooling water and saturated air to dehumidifier as its decision variable. A sensitivity analysis, furthermore, is performed to distinguish the effect of operating parameters including mass flow rate and streams’ temperature. The results showed that the optimum productivity decreases by decreasing the ratio of mass flow rate of water entering humidifier to air ones.Article History: Received: July 12th 2017; Revised: December 15th 2017; Accepted: 2nd February 2018; Available onlineHow to Cite This Article: Afshar, M.A., Naseri, A., Bidi, M., Ahmadi, M.H. and Hadiyanto, H.

Impact of Blanket Configuration on the Design of a Fusion-Driven Transmutation Reactor
Authors: Hong Bong Guen
Published: February 2018

A configuration of a fusion-driven transmutation reactor with a low aspect ratio tokamak-type neutron source was determined in a self-consistent manner by using coupled analysis of tokamak systems and neutron transport. We investigated the impact of blanket configuration on the characteristics of a fusion-driven transmutation reactor. It was shown that by merging the TRU burning blanket and tritium breeding blanket, which uses PbLi as the tritium breeding material and as coolant, effective transmutation is possible. The TRU transmutation capability can be improved with a reduced blanket thickness, and fast fluence at the first wall can be reduced. Article History: Received: July 10th 2017; Received: Dec 17th 2017; Accepted: February 2nd 2018; Available onlineHow to Cite This Article: Hong, B.G.

Published: February 2018

Sulfonated polyether ether ketone (SPEEK) was utilized as a proton exchange membrane (PEM) in Microbial Fuel Cell (MFC). The SPEEK performance in producing electricity had been observed in MFC using wastewater and glucose as substrates. The MFC with catering and tofu wastewater produced maximum power density about 0.31 mW/m2 and 0.03 mW/m2, respectively, lower that of MFC with tapioca average power density of 39.4 W/m2 over 48 h. The power density boosted because of the presence of Saccharomyces cerevisiae as inoculum. The study using of S. cerevisiae and Acetobacter acetii, separately, were also conducted in with glucose as substrate. The MFC produced an average power densities were 7.3 and 6.4 mW/m2 for S. cerevisiae and A. acetii, respectively. The results of this study indicated that SPEEK membrane has the potential usage in MFCs and can substitute the commercial membrane, Nafion.Article History: Received: Juni 14th 2017; Received: Sept 25th 2017; Accepted: December 16th 2017; Available onlineHow to Cite This Article: Putra, H.E., Permana, D and Djaenudin, D.

Published: February 2018

In this paper, a novel four-level flying capacitor inverter and its comparison with the conventional flying capacitor topology in terms of THD analysis are proposed. This new topology have some advantages over conventional one as following: The blocking voltages are the same for all switches used in the configuration, there is no need for capacitor midpoint connection and this eliminates low frequency current which circulate in dc-link capacitors, and the number of flying capacitor is reduced as compared with conventional form of it. The operation of the topology, modulation strategy, simulation results, and THD analysis for the output waveforms are presented in this paper.Article History: Received: 17th July 2017; Received: October 14th 2017; Accepted: Januari 18th 2018; Available onlineHow to Cite This Article: Gülpınar, F., Sarı, F., and Uzun, Y.

Improving the Efficiency of a Nuclear Power Plant Using a Thermoelectric Cogeneration System
Authors: Terzi Rauf , Kurt Erol
Published: February 2018

The efficiencies of nuclear power plants are rather poor having the ratio %30 by using the conventional energy/exergy tools. According to that information, large amount of energy is wasted during condensation and thrown out to the environment. Thermoelectric generator (TEG) system has a potential to be used as a heat exchanging technology to produce power with a relatively low efficiency (about 5%) and it can transform the temperature difference into electricity and generate clean electrical energy. In the present study, we offer a novel system to recover the waste heat from a VVER-1000 nuclear power plant. The heat transfer of the TEG is analyzed numerically with respect to the various temperature ranges and constant mass flow rate of the exhaust steam entering the system. In the analyses, different hot temperature ranges (35ºC, 45ºC and 55ºC) and a constant cold temperature (i.e. 18ºC) are used for a HZ-20 thermoelectric module and it has been proven that the designed TEG can produce the maximum output power of 76,956 MW for a temperature difference ∆T=37 and the conversion efficiency of 3.854% sits. The TEG is designed for the condenser of a 1000 MW nuclear power plant. It's shown that about 2.0% increasing in the power plant efficiency is expected by using the selected thermoelectric generator in the condensation cycle.Article History: Received: July 15th 2017; Received:  October 17th 2017; Accepted: February 13rd 2018; Available onlineHow to Cite This Article: Terzi, R. and Kurt, E.

Social media use by instructional design departments
Authors: Romero-Hall Enilda , Kimmons Royce , Veletsianos George
Published: February 2018

The aim of this investigation was to gain an understanding of the use of institutional social media accounts by graduate departments. This study focused particularly on the social media accounts of instructional design (ID) graduate programs. Content and statistical analyses were conducted to examine 24,948 tweets posted by ID programs (n = 22) on Twitter. Results revealed that ID graduate programs primarily used Twitter to broadcast resources and materials related to the field. Additionally, results showed that ID programs most frequently used Twitter to boost the profile of their program. Yet, tweets highlighting student and faculty accomplishments had the highest percentage of community interactions (likes and retweets). These findings suggest that ID programs are functioning as filters of information relevant to the field rather than conversational hubs.
