In communication system the requirement of bandwidth enhancement is the most necessary requirement. This requirement of bandwidth increment can easily achieve the data rate of the system, so for further development of communication system higher bandwidth is required. Wireless communication already covered most of the frequency range till five giga hertz. In fractal technique structure which is similar in shape are designed for the similar nature of the radiation to increase the radiative power. By fractal radiation area can be increased, is used to achieve the bandwidth of the signal. By fractal technique size of the antenna can also be reduced for miniaturization of the device which is going to be developed. In this paper a different rectangular antenna is presented, consists of dual properties, is fractal and defected ground. This paper shows simulated result and designed hardware result and also shows the comparative result of these. In defective one rectangular slot has been introduced. A higher bandwidth rectangular antenna has been simulated and designed and a comparative analysis of simulated and hardware results compared and analyzed. Simulation done by considering 4 GHz as center frequency. The easily available material FR-4 is used for simulation as well as hardware design. In this substrate thickness will be 1.6mm. Return loss of the given design is achieved less than -10db for almost 11GHz. In future the many applications will use this range of frequency. The value of VSWR is also achieved less than two for 3GHz to 14GHz. Simulation of this design is done by HFSS software. The ground plane is also modified for enhancement of bandwidth.

This paper features an effective technique to device the parameters of PID controllers for utilization together with an Automatic Voltage Regulator System (AVR). The quintessential goal is to acquire a good load disturbance response by minimizing the performance index/(Integral time square error). Simultaneously, the transient response is assured by limiting maximum overshoot, settling time and rise time of the step response to minimal values. For achieving these goals, optimum and quick tuning of the parameters (Kp, Ki, and Kd) is essential. In an effort to accomplish the aforementioned, the paper put forth an algorithm developed based on the Ant Colony Optimization technique (ACO) to decide optimal gains of PID controller and for getting optimal performance within an AVR system. Simulation results establish superior control response may be accomplished in comparison with methods like conventional tuning method (trial and error) and built-in genetic algorithm (GA) took-kit.e.

Published: March 2020

The aim of the present study is to investigate the effects of three different steroid hormones; 17 β estradiol, Diethylstilbestrol and progesterone on cell viability in F98 glioblastoma cells. F98 glioblastoma cells were treated with different concentrations of Progesterone (10, 20, 50, 100 μM), DES (2.5, 5, 10, 20, 50, 100 μM) and 17β estradiol (0.01, 0.1, 1, 10 μM)) for 24, 48 and 72 hours and MTT assay was applied to determine thecell viability. Progesterone inhibits glioblastoma cell growth in a dose and time dependent manner. Antiproliferative effect of 17 β estradiol was observed at low doses. Biphasic distribution was observed in decreasing cell viability in DES applications. These results suggest that Progesterone, 17β estradiol and DES can inhibit the proliferation of glioblastoma cells. However, further study is necessary to identify the pathways involved.Bu çalışmada 17 β  östradiol, Dietilsitilbesterol ve
progesterone gibi steroid hormonların F98 glioblostomo hücre hatlarında hücre

Targeting apoptosis via inactivation of PI3K/Akt/mTOR signaling pathway involving NF-κB by geraniin in HT-29 human colorectal adenocarcinoma cells
Authors: Chan Chim Kei , Tang Liu Ying , Goh Bey Hing , Abdul Kadir Habsah
Published: March 2020

Dietary phytochemicals possess a variety of biological activities which can be widely discovered in fruits, vegetables and herbs. Geraniin, an ellagitannin is commonly found in fruits and herbs which possesses multitude of health benefits including anti-diabetic, hepatoprotective, anti-inflammatory and anticancer. However, the effects of geraniin on human colorectal adenocarcinoma cells have yet to be evaluated. This study aimed to investigate the apoptotic effects of geraniin against selected human cancer cell lines and elucidate its underlying mechanisms. Geraniin exhibited the strongest cytotoxic effect on HT-29 cells as determined by MTT assay. Events of apoptosis induced by geraniin in HT-29 cells was portrayed by apoptotic morphological changes, externalization of phosphatidylserine, DNA fragmentation and dissipation of mitochondrial membrane potential. Western blot analysis was then used to investigate the mechanisms underlying observed growth inhibition. Geraniin was found to initiate p53 activation further resulting in elevation of Bak/Bcl-xL ratio and caspase-3 activation. This eventually led to HT-29 cell death via apoptosis. Additionally, exposure of geraniin on HT-29 cells found to suppress the PI3K/Akt/mTOR pathway and suppression of NF-kB. Cumulative evidences in this study suggests that geraniin inhibited colorectal adenocarcinoma cell proliferation via apoptosis induction and suppression of PI3K/Akt/mTOR pathway. Thus, these findings provide novel mechanistic insight for the therapeutic potential of geraniin in the treatment of colorectal adenocarcinoma.
A reliable and reproducible assay for determining the effect of natural product on macrophages lipid uptake and cholesterol efflux: A case study of maslinic acid
Authors: Ooi Bee Kee , Ahemad Nafees , Yap Wei Hsum
Published: March 2020

Macrophage foam cell formation represents a key feature that contributes to the development of atherosclerotic lesions. Assessment of cardioprotective natural compounds targeting macrophage foam cell formation processes including lipid uptake and cholesterol efflux could lead to the identification of potential lead compounds for development into novel anti-atherosclerotic drugs. In this case study, maslinic acid, a natural product was used to study the effect on lipid uptake and cholesterol efflux in THP-1-derived macrophages.  Oil red O (ORO) staining and 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate-labeled oxidized low-density lipoprotein (Dil-labeled oxLDL) uptake assays were performed to determine lipid uptake by macrophages while cholesterol efflux was assessed using 3-hexanoyl-NBD labeled cholesterol. ORO-stained images were further analyzed using ImageJ analysis software to determine intracellular lipid droplets accumulation and flow cytometric analysis of mean fluorescence intensity were obtained to quantify Dil-labeled oxLDL uptake by macrophages. Meanwhile, 3-hexanoyl-NBD labeled cholesterol uptake and efflux from THP-1-derived macrophages were characterized. The fluorescence intensity values obtained from the medium and cell lysates were then converted into percentage of cholesterol efflux. The results have shown that incubation with maslinic acid suppressed oxLDL-induced macrophage foam cell formation which may be contributed from its effect in reducing lipid uptake and enhancing cholesterol efflux. In conclusion, the optimized ORO staining, Dil-labeled oxLDL uptake, and fluorescent-labeled cholesterol efflux assays provide reproducible and reliable results for assessment of foam cells formation.
Role Play in Drug Discovery and Development: Biosciences student performance and perspectives when role play experiential learning activities are integrated into learning
Authors: Yap Wei Hsum
Published: March 2020

Objectives: Science education should not be viewed as absolute and unchanging. Instead of teaching a multitude of facts that might change tomorrow, there should be an emphasis on supporting learners to develop adaptability and ability to connect prior knowledge with future utility. Experiential learning in the form of role play offers accelerated learning experience and connect students to the real world setting. Role play activities deploy a student-centered approach that empowers students to take learning into their own hands and apply it in an engaging context. This paper describes the design and implementation of role play simulation activities for the module principles of drug discovery and development for Biomedical Science and Biotechnology students in the School of Biosciences at Taylor’s University, Malaysia.Methods: Students were taught about the principles of drug discovery and development; at the end of the semester, a role play experiential activity was introduced. Students' performance between different cohorts was compared before and after the implementation of the role play and qualitative responses using open ended questionnaire were collected. Alongside the questionnaire an evaluation was also completed by the students for the module-based responses.Results: Student evaluation of the role play experiential activity was positive. Applying knowledge in real life scenarios, interactive, and cooperation as a team emerged as the main themes of biosciences students to the activity. Students indicated that the role play activity helped with the application drug discovery and development concepts and enabled them to collaborate as a team in the activity. In addition, evaluation have shown that it enhances their ability to relate subject matter to real world examples, connecting the relationship of lesson activities to learning objectives and outcomes as well as improving their communication skills. The overall performance results for the module have also improved upon introduction of the activity compared to the last offered semester.Conclusion: Students had better performance and expressed favorable responses after the introduction of the role play activity. Role play represents a beneficial tool in terms of understanding and application of complex concepts in the area of drug discovery and development.

Published: March 2020

The paper examines the intra-regional trade of the automotive industry in East-Central Europe as the prioritized target of foreign direct investment and a production site of growing importance in the sector. Our main assumption is that cross-border agglomeration tendencies (reflected in intra-regional trade relations), with the upgrading of the region, play an increasingly important role. After a review of the relevant literature, the paper analyses and explains how the significance and the structure of the connections within the region have recently changed. The empirical survey focuses on the first decade of the 21st century, with the East-Central European countries (Czechia, Hungary, Poland, Romania, Slovakia and Slovenia) characterized by the considerable presence of the automotive industry.
Learners’ Work in a SALC: A Longitudinal Study
Authors: Madrid Durazo Victoria , Castillo Zaragoza Desirée
Published: March 2020

Self-access centers (SACs) became popular in Mexico in the 1990s with the purpose of allowing learners to make decisions about how to learn languages. The following study is qualitative and longitudinal and was carried out in the SAC at the University of Sonora in Mexico. It was designed with the purpose of understanding learners’ performance as they direct their own learning in a SAC. By focusing on learning experiences, activities, and materials, the results show that learners understand the idea of language learning in SACs in a limited way. However, the participants view learning in a SAC to be an effective approach to learning languages due to the progress and growth they noticed.
Social Language Learning Spaces: Globalization Glocalized
Authors: Murray Garold , Uzuka Mariko , Fujishima Naomi
Published: March 2020

In this era of globalization, Japanese universities will have to accommodate an increasing number of local students wishing to learn foreign languages and they will also have to welcome more international students to their campuses. While universities will undoubtedly take steps to ensure that both groups have positive educational and intercultural experiences, we contend that it is also incumbent upon them to implement measures designed to facilitate the adaptation of international students to Japanese society. In this article, we examine the role social learning spaces can play in helping universities respond to these challenges. We argue that these facilities can make an invaluable contribution by supporting language learning and cross-cultural acclimatization for both international and Japanese students. The term social learning spaces refers to places where students can come together in an informal or quasi-formal environment in order to learn from and with each other. To illustrate our points, we draw on the data from a five-year ethnographic inquiry carried out at one such facility on the campus of a large national university. After describing the social learning space, outlining the study, and tracing the theoretical orientation guiding the interpretation of the data, we focus on the benefits social learning spaces can afford international students wishing to improve their language skills and adapt to Japanese society. To conclude, we reflect on how social learning spaces can support the process of glocalization by making local universities more globalized places.
Peer Tutoring: Active and Collaborative Learning in Practice
Authors: Ruegg Rachael , Sudo Taku , Takeuchi Hinako , Sato Yuko
Published: March 2020

The mandate of self-access centers is to provide a venue, materials and support for self-directed learning; taking learning outside of the classroom. The Academic Achievement Center (AAC), on which this paper focusses, is a support service offered within a self-access center at a university in Japan. Students who receive support do so on a completely voluntary basis, in a self-directed effort to support and enhance their classroom learning. This paper was written as a collaboration between the coordinator of the AAC and three peer tutors, who were employed in the center. At the time of writing, one of the authors was a student in the Graduate School of Japanese Language Teaching Practices, while two were undergraduate students in the Faculty of International Liberal Arts; taking their learning outside of the self-access center and sharing it with a wider audience. This paper was motivated by the desire on the part of the peer tutors to share what we are doing in the AAC with those thinking of, or in the process of, creating a tutoring center, especially in Japan. Additionally, it was written to give readers an insight into how a tutoring center in an international university in Japan is run, as well as its successes and challenges. The paper itself is a co-authored publication by a professor and a few student-tutors, representing the vast possibilities of active and collaborative research which can be done in a university setting.
Effects of Drawing and Sharing a ‘Picture of Life’ in the First Session of a Mentoring Program for Experienced Learning Advisors
Authors: Kato Satoko
Published: March 2020

Since language learning relates to learners’ life events, Learning Advisors (advisors) who are professionals in promoting learner autonomy through conducting reflective dialogue with learners, often tap into learners’ life stories in advising sessions. The previous studies on the life narrative approach indicate that storytellers construct personal meaning and stronger self-image while telling their stories (Bruner, 1990; Erikson, 1968). Atkinson (1998) indicates that creating visual images ahead of time could help storytellers prepare to tell their life stories.

This study investigates the effects of drawing a ‘picture of life’ (PL) and sharing it in the first session of a professional development (PD) program where one-to-one mentoring sessions were conducted between five experienced advisors and the author during a period of six months. Data were collected from written journals and post-mentoring questionnaires. A qualitative analysis was conducted to investigate the effects of conducting the PL activity in the first session. The results showed that the PL activity not only helped the storytellers bring new insights and meanings to their professional and personal lives, but also it served as a ‘point to return to’ which became a strong thread throughout the following sessions.
Conceptualizing Leadership Development in the KUIS SALC
Authors: Knight Kevin
Published: March 2020

On the campus of Kanda University of International Studies (KUIS) in Chiba, Japan, a proposal was presented for the leadership development of KUIS students in the KUIS Self-Access Learning Center (SALC) (Knight, 2017). Following Scollon (2001) and his mediated discourse analysis (MDA)-based nexus of practice concept, this paper explores how and why multiple storylines and histories intersect so that ‘leadership development’ is conceptualized as consulting programs in the SALC. The paper shows that Knight’s (2013) conceptualization of leadership as involving communication for creating and achieving visions is the basis for the proposed consulting programs and concludes by asking how leadership and learner autonomy should be conceptualized in a self-access learning center.
Principles of my TOEIC Test-Prep Workshops and Self-Access Online Materials for TOEIC Preparation
Authors: Yamaguchi Atsumi
Published: March 2020

This short article summarizes my reflections and opinions toward my optional workshops on TOEIC preparation. The workshops have taken place weekly in a self-access center (SAC) in Chubu district, Japan. Many SACs, in fact, offer workshops as a part of their services encouraging learners to enhance their target language proficiency and become more self-regulated and autonomous (Gardner & Miller, 1999; Sekiya, Mynard, & Cooker, 2010). However, few have researched whether SAC workshops are achieving such goals. Thus, I aim to share my perspectives based on my reflections on having instructed the series of workshops for the duration of four semesters. In particular, I will present my three principles to make the workshops attractive and effective: 1) learner development; 2) implications from second-language acquisition (SLA); and 3) guidance on learning resources. I will also illustrate learning resources found to be most popular by my workshop attendees. Finally, I will discuss key elements that may make SAC workshops more meaningful and distinguished as extra-curricular lessons.

Interview: Learning the Core Concept of Extensive Reading from Richard Day
Authors: Tabta-Sandom Mitsue
Published: March 2020

Extensive Reading is probably one of the hottest topics in the context of second and foreign language (L2) reading instruction (Iwahori, 2008). Krashen’s Input Hypothesis (Rodrigo, Krashen, & Gribbons, 2004) theoretically supports ER in which L2 learners’ reading development and motivation to read are nurtured by exposure to a large quantity of comprehensible and interesting input. Graded Readers (GRs), lexically and syntactically graded readers, form a core of such facilitative input in ER. In this interview, Professor Richard Day, the Founding Chair Emeritus of the world-wide leading Extensive Reading Foundation, talks about the fundamental concept of L2 reading instruction. Furthermore, he gives encouraging support and input to readers of The Language Teacher who have embarked on and want to start the practice of ER. Professor Day has been tirelessly promoting ER through L2 teacher education for many years.
The Role of Student-Led Social Media Use in Group Dynamics
Authors: Lawrence Luke
Published: March 2020

In recent years, teachers and researchers have begun to investigate and make use of the role of new technology and social media in language classrooms. This study focuses on the role of student-led social media, completely free of teacher input, and the influence and perceived positive effects it can have on group bonding and cohesion. It found that participation in a class LINE group was utilized for a variety of practical and personal purposes, which was seen by the students to have had a positive effect in terms of building relationships and providing a supportive and enjoyable information network of peers. This can be said to have led to a more cohesive and bonded group that felt engaged and committed to the class.

Neural bases of social feedback processing and self–other distinction in late childhood: The role of attachment and age
Authors: Miller Jonas G. , Shrestha Sharon , Reiss Allan L. , Vrtička Pascal
Published: March 2020

Attachment plays a key role in how children process information about the self and others. Here, we examined the neural bases of interindividual differences in attachment in late childhood and tested whether social cognition-related neural activity varies as function of age. In a small sample of 8-year-old to 12-year-old children (n = 21/19), we used functional magnetic resonance imaging to measure neural responses during social feedback processing and self–other distinction. Attachment was assessed using child self-report. The social feedback processing task presented smiling and angry faces either confirming or disconfirming written information about participant performance on a perceptual game. In addition to observing main effects of facial emotion and performance, an increase in age was related to a shift from negative (i.e., angry faces/bad performance) to positive (i.e., smiling faces/good performance) information processing in the left amygdala/hippocampus, bilateral fusiform face area, bilateral anterior temporal pole (ATP), and left anterior insula. There were no effects of attachment on social feedback processing. The self–other distinction task presented digital morphs between children’s own faces and faces of their mother or stranger females. We observed differential activation in face processing and mentalizing regions in response to self and mother faces versus morphed faces. Furthermore, left ATP activity was associated with attachment anxiety such that greater attachment anxiety was related to a shift from heightened processing of self and mother faces to morphed faces. There were no effects of age on self–other distinction. We discuss our preliminary findings in the context of attachment theory and previous work on social evaluation and self–other processing.
The Multidimensionality of the Symbolic Universe of Roman Romanyshyn
Authors: Stoian Svitlana
Published: March 2020

The article presents an analysis of the symbolic contexts of the creativity of Lviv artist Roman Romanyshyn, whose works are distinguished not only by filigree execution technique and innovativeness but also by multilayered symbolic meanings, which in the space of his personal exhibition have become a deep and consistent visual story. The artist uses symbolic codes at a subconscious level, not by a pre-conceived concept, which is the most consistent with the nature of symbolic masterpieces, creating and decoding of which one cannot accomplish solely by reason. The author turns to geometric symbolizations using, for example, the image of a large-scale triangle consisting, in its turn, of numerous triangular etching puzzles with symbolic images to visualize the idea of the social hierarchy. Furthermore, following the escalating graphic experiments of M. C. Escher, the artist creates a Magic Cube and many other filigree etchings that appear before the eyes of the viewer as symbolic labyrinths, which encode numerous codes, thanks to which each of us, depending on the individual content of one’s inner world, can build peculiar symbolic-associative chains, acting as co-creator of multilayered works of the author.
Sacralization of Everyday Cultural Practices
Authors: Miednikova Halyna
Published: March 2020

The concept of ‘cultural practices’ makes it possible to explore the behavior of the individual in the different socio-cultural coordinates, to search a complex set of value-meaning installations, to study the sign-symbolic system, ways of communication, as well as artistic realities of everyday life. The article considers the content of such new cultural practices as culinary practices, night cultural and entertainment practices, participation in festive activities (Kyiv City Day, Independence Day, embroidery holiday, borsch, dumplings, Bouquet Kyiv Stage, etc.). These projects capture the transformation of the individuals’ value orientations in the styles of mass behavior, focusing on such important attributes as the sacralization of everyday life. In the article, the methodology for the study of cultural practices is systematized: cultural studies, cultural studies of everyday life, ‘meta-practice’ of everyday life of M. Epstein, outlined the strategy of sacralization in new cultural practices.
Transculturality as a Modern Theoretic Concept in an Interdisciplinary Academic Space
Authors: Otreshko Nataliia
Published: March 2020

The purpose of the article is to analyze the trends in the use of the concept of transculturality existing in the global scientific discourse and to identify the main directions of development of this concept.
Methodology. An evolutionary analysis of the formation of the three main approaches in the analysis of transculturality provides a practical test of the intermediate results in specific historical examples. System analysis will show the regularity and necessity of studying the evolution of transcultural systems, taking into account their dynamics from the perspective of the future.
Results. Drawing on a comparative approach, the author identifies three main areas of development of the concept of transculturality in contemporary scientific discourse. The first one continues the tradition of classical German philosophy of culture. The second area of transculturality studies is related to the ideological disputes of neoliberals and postcolonialists. The third area of research is purely practical, helping to solve the problems of transcultural communications in the field of business.
Originality. For the first time, three different approaches to the study of transcultural phenomena are identified and analyzed, and their methodological and ideological differences are proposed.
Practical meaning. The information contained in this work can be used to further research and development of methodological material for new courses of lectures and seminars on cultural philosophy and methodology for studying contemporary transcultural processes.
Self-regulating System of Academic and Civic Movements (the Case of Climate Change)
Authors: Haievska Tetiana
Published: March 2020

The aim of this paper is to analyze the campaign on global warming raised by academic communities and taken up by civic (environmental) movements. The self-regulating system of these movements involved certain mechanisms that ensured communication of the social organization, and this, in turn, stimulated the informational and cognitive activity of society.
Methodology. The author uses as a methodological basis of this study the principles and methods of the culturological approach to the analysis of numerous publications concerning problems of global warming raised by academic communities and taken up by civic (environmental) movements.
Results. The alliance between scientists, environmentalists and opinion leaders has ultimately brought the issue of global environmental change into the public order of the day.
Novelty. In the article, our attention is focused on two different types of civic movements (academic society and social movements, in our case environmental ones). A new environmental consciousness is being created that leads to the widespread awareness of the reality, causes and effects of climate change through science-driven civic movements operating in and through the media and the Internet. Using the Internet as an organizational and advisory facilitator to engage and unite citizens, the pressure is placed on governments to address environmental issues.

MODEL PREDICTIVE CONTROL OF A HYDRAULIC ACTUATOR IN TORQUE APPLYING SYSTEM OF A MECHANICALLY CLOSED-LOOP TEST RIG FOR THE HELICOPTER GEARBOX
Authors: Parvaresh Aida , Mardani Mohsen
Published: March 2020

Transmission health is an important factor in safety and maintenance costs in industries, so construction of test rigs for testing
high-powered gearboxes under different operating conditions of helicopters is required. The studied test rig, which is developed at Sharif University of
Technology branch of ACECR (Academic Centre of Education, Culture and Research) is mainly used for testing high-powered gearboxes through a mechanically
closed-loop procedure. For providing a variety of speeds and torques in test rigs, torque applying system is required. According to generation of higher
forces, reduced size of equipment and accurate positioning, electro hydraulic actuators (EHAs) are used for applying torques for planetary gearboxes of
this test rig. Due to the importance of applying accurate torques in evaluation of the gearbox performance, first an accurate model of EHA is derived,
which captures the system dynamics using system identification method with low consumed time and simple relations. After that, a type of model predictive
controller called dynamic matrix controller is proposed for controlling EHA under determined requirements. Then, the performance of proposed controller
under normal conditions as well as in presence of disturbance is investigated. The results show a good tracking of controller for various reference inputs
in different conditions. Moreover, the performance of the proposed controller is compared with the performance of classical proportional-integral-derivative
(PID) controller and superior characteristics of the proposed controller is concluded.
