Background: Ischemic stroke that occurs at the age of less than 45 years accounts for about 5 until 10 percent of the total stroke. This is inﬂuenced by changes in the life-style of modern society, such as changes in the pattern of food consumption, lazy to move, and smoking habits. This study aims to examine the effect of life-style on ischemic stroke at less than 45 years old people.Method: This study uses observational method with design of cases and controls. The samples are 86 observations consisting of 43 cases and 43 controls. Cases are patients with ischemic stroke less than 45 years of age and controls are non-stroke patients of neurology who are less than 45 years old.Results: The results show that the habit of consuming food containing high fat (p=0,032, OR=3,744, 95% CI=1,124-12,468) and smoking habit (p=0,019, OR=3.859, 95% CI=1,250-11,911) affect the occurrence of ischemic stroke at age less than 45 years. However, the habit of consuming red meat, consuming foods containing high salt, consuming drugs, and lack of physical activity do not affect the occurrence of ischemic stroke at age less than 45 years.Conclusion: The habits of consuming food containing high fat and smoking affect theoccurrence of ischemic stroke at age less than 45 years after hypertension, heart disease, and diabetes mellitus are controlled.
The Depiction of the Saracen Foreign Rule in the Prophetic Chronicle Through Biblical Knowledge
Authors: Marschner Patrick S.
Published: January 2019

The intention of this article is to interpret the biblical elements in the Prophetic Chronicle concerning their role in the process of identification of the cultural and religious Other in the Iberian Peninsula. To understand the Christian strategies of identification, the article contrasts the biblical elements in the text with their appearance in the Bible and compares the corresponding narrations. Since the contemporary foreign rulers over major parts of the former Visigothic kingdom were named almost entirely with biblically connoted ethnonyms, understanding these denominations is necessary to investigate both the perception and depiction of the Arab rulers of Hispania. Consequently, this article can point out the importance of the biblical elements in Christian-Iberian historical writing for research on the transcultural Iberian Peninsula and simultaneously offers new insight about the Prophetic Chronicle.

Authors: Fernández Benavides Alejandro
Published: January 2019

The emergence of language learning websites has generated changes in intercultural communicative practices. Particularly, these sites use a wide variety of modes of communication (visual, linguistic, spatial) which allow the presence of intercultural elements. This interpretative case study analyzes the semiotic structure of one lesson of the language learning website Livemocha in order to unveil the presence of intercultural elements in it. Data were analyzed following a method for multimodal analysis and Byram’s model of intercultural communicative competence. Findings suggest the essentialist view of culture on Livemocha, based on festivals and food, and the potential promotion of some of Byram’s intercultural skills.

Authors: Sanfelici Aline , Figueiredo Eduardo Diniz de
Published: January 2019

This study addresses the need for more research into the education of English language teachers in PARFOR programs. Through the analysis of questionnaire and interview data, we investigate the perceptions and reported practices of teachers who were enrolled in a language and culture PARFOR course in 2012 (in a northern state) in relation to their teaching practices after completion of the program. The results indicate that since the end of the course, some participants have shown a growing level of awareness towards working with an intercultural approach, which has reflected upon their practices. However, others still seem to show more traditional, less interculturally-oriented approaches to teaching language and culture. Implications for teacher education are presented.

Authors: Serafim Valeska Favoretti , Meireles Alexsandro Rodrigues
Published: January 2019

This study aims to analyze the affordances of Edmodo (https://www.edmodo.com), the leading k-12 Social Learning Network (Edmodo, 2018), for the flipping and expansion of foreign, second or additional language (L2 henceforth) classroom. To do so, we first had a brief review of literature on blended learning and selected one of its sub-models suggested by Horn and Staker (2014) – the flipped classroom – to focus on. Then, we considered ten out of the fifteen reasons Bergmann and Sams (2012) shared on why teachers should flip their classrooms and described Edmodo’s main features. Finally, we developed Bergmann and Sams’s ten reasons into four practical reasons on why teachers should consider flipping and expanding their classrooms with Edmodo and spoke about our experiences on this platform. This study showed that the various features of this free platform make it an excellent tool for such purposes and we recommend that teachers take advantage of it and adapt it to their contexts.

Pemanfaatan sumber daya di wilayah pesisir mencakup konteks sosial multiple use, berbagai bentuk kepemilikan, dan konflik atas penggunaan sumber daya. Sistem ekologi di daerah  pesisir sangat berhubungan erat dengan/dan dipengaruhi oleh satu atau lebih sistem sosial. Pendekatan kontemporer pengelolaan pesisir dan lautan berbasis sosial - ekologi pada dasarnya adalah integrasi antara pemahaman ekologi (ecological understanding) dan  nilai – nilai sosial ekonomi (socio-economic value).  Analisis sistem ekologi-sosial (SES) dalam pengelolaan wilayah pesisir terpadu  mampu memberikan suatu pendekatan yang interdisipliner dan framework pengelolaan sumber daya yang berkelanjutan. Analisis SES dapat menjadi basis pengetahuan untuk mengatasi secara sistematis masalah yang kompleks dalam pengelolaan pesisir secara terpadu, selain itu juga dapat mengembangkan suatu strategi berbasis pengetahuan dalam memahami proses-proses ekologi dan sosial pada dimensi sistem dan skala yang berbeda.Title: Social – Ecological System (SES) Approach In Integrated Coastal ManagementUtilization of resources in coastal areas includes multiple use social contexts, various forms of ownership, and conflicts of interest. The purpose of this paper is to learn about the Social-Ecological System approach in integrated coastal management. Ecological systems in coastal areas have a very close relationship with / and are influenced by the social system. Basically the contemporary approach of coastal management based on social-ecology system (SES) is the integration between ecological understanding and socio-economic value. SES analysis in integrated coastal area management is able to provide an interdisciplinary approach and a sustainable resource management framework. SES analysis can be a knowledge base for dealing systematically with complex problems in integrated coastal management, while also developing a knowledge-based strategy in understanding ecological and social processes in different dimensions of the system and scale.
A Critical Look at the Bigger Picture
Authors: Hellmich Emily A.
Published: January 2019

Despite its numerous benefits and potentialities for language learning and teaching, digital technology can also play a role in creating and maintaining inequality (Kern, 2014; Selwyn, 2013). While critical CALL often focuses on micro-level issues and contexts, macro-level perspectives, including discourses, are also essential to consider (Helm, 2015): From ecological and language-as-discourse perspectives, macro-level discourses have the potential to impact and shape CALL practices and contexts (Blin, 2016; Blommaert, 2005). Using critical discourse analysis methods (Blommaert, 2005; Fairclough, 2001), this article takes the 2017 American Academy of Arts and Sciences (AAAS) report, "America’s Languages: Investing in Language Education for the 21st Century," as a window into macro-level discourses of language and technology in American society today. Findings reveal a series of interrelated frames and scales that, taken together, suggest a neoliberal discourse that positioned language, technology, and ultimately CALL as tools to enhance national competitiveness on a global marketplace. The article concludes with implications of these findings for the CALL field.
“This May Create a Zero-lingual State”
Authors: Song Rayoung
Published: January 2019

Given the importance of the blogosphere for autonomous language learning, many studies on computer-assisted language learning (CALL) have vigorously investigated the use of blogs in language learning. Noticeably lacking in these endeavors are investigations of language learners’ social engagement with others in online spaces to define and negotiate their own meanings of language and language learning. To fill this gap, this study investigated the language ideologies disseminated in a Korean blog that has become a collaborative online English-learning community. Focusing on this blog owner’s ideas and her followers’ responses, I explored the language ideologies disseminated and negotiated in conversations on language learning and using. This is part of a larger virtual ethnographic study conducted over the past three years. I analyzed online posts and comments using Gee’s situated meanings (2014). Findings suggest that the Korean bloggers subscribe to monolingual ideologies because they are acutely aware of the ideological contexts in Korea surrounding English and are critical about their own language learning and using practices. The current study asserts that the blogosphere can create opportunities for language learners to contest existing knowledge and voice their opinions on issues that matter to them as language learners and members of a society.

The effect of nanodispersed iron oxide additives on the formation of the density of carbon refractories
Authors: Apal'kova G. D.
Published: January 2019

It was established that the addition of nanodispersed iron oxide pigment in an amount of 0,25‒0,50 % provides directional regulation of the chemisorption interaction of the binder and fller during mixing, contributing to an increase in the density of carbon refractories. It is shown that when introducing nano-additives into the carbon composition, it is necessary to adjust the mass of the binder in the direction of reducing its content. The principle of selecting the optimal binder content as a result of the plasticizing eﬀect of nanodispersed iron oxide pigment at the maximum torque on the mixer shaft corresponds to a high level of expended mechanical energy and, accordingly, to intensify the mixing process and provides an increase in the sintering mass during fring.Ill.5.

Published: January 2019

The high angle belt conveyor with the cross ridge partitions is proposed in the article which allows to increase significantly not only its belt angle but also the transported weight cargo at the expense of the more eﬀective flling and resistance to the force of gravity. The methodology of the high angle belt conveyor calculation is fnalized with regard to the defning of the forces and strains which inﬂuence the pressing lever. The graphical and mathematical models are proposed to depict the force interaction between the substructure elements and the transported weight load. The equation was derived for the maximum bending moment due to the conveyor structural features which now allows to calculate both the geometrical parameters of the press lever and the necessary compressed spring force. Taking into account the friction coefcient, the force of gravity and the additional force which is transmitted on both the diaphragm and the conveying belt the optimal range of the conveyor's belt angle was defned which provides the material consumption reduction at the designed productivity comparing with the conventional conveyors.Ill.4.

The aim of this study was to analyze the lipid profile in serum of patients with diabetes mellitus type 2, and its relationship with HbA1c levels.

Methods: The observational cross-sectional study included 60 diabetic patients, 30 men, and 30 women, age 32–94 years. Patients were assigned into two groups based on HbA1c values; Group 1: HbA1c ≤ 7% (good glycemic control) and Group 2: HbA1c > 7% (poor glycemic control). We analyzed the concentration of glucose, HbA1c, and lipid profile including total cholesterol levels, triglycerides (TAG), low-density lipoproteins (LDL), and high-density lipoproteins (HDL).

Results: Significantly lower values of glucose concentration, TAG and the ratio TAG/HDLc were obtained in the group of patients with good glycemic control. (p < 0.0005) Patients with good glycemic control had lower values of Castelli 1 and Castelli 2 index, and atherogenic index of plasma, compared to patients with poor glycemic control, but this difference was not significant. (p > 0.005) Our study revealed a significant positive correlation between HbA1c and triglyceride level (r = 0.375; p = 0.003) and HbA1c and ratio triglyceride/HDLc (r = 0.335; p = 0.009).

Conclusion: HbA1c can also be used as a predictor of dyslipidemia in type 2 diabetics in addition to as a glycemic control parameter.

Hisse Senedi Getirilerinin Marka Değeri Duyurularına Tepkisi
Authors: ERGÜN Bahadır
Published: January 2019

Bu çalışmada Türkiye marka değeri
sıralamasında ilk 10’a girebilmiş firmalarının hisse senetlerinin bu duyuru
öncesi ve sonrası ne şekilde fiyatlandığının araştırılması amaçlanmıştır. Bu bağlamda
2012 ve 2017 yılları arasında Brand Finance tarafından ilan edilen Türkiye’nin
En Değerli Markaları Yıllık Raporu’na giren ilk 10 şirketin düzeltilmiş günlük
hisse senedi fiyatları ve BIST100 endeksine ait günlük veriler kullanılmıştır.
Analiz yöntemi olarak olay etüdü yöntemi seçilmiştir. Yapılan analiz sonrasında
yatırımcıların marka değeri duyurularına verdikleri tepkinin daha çok ilk
yıllarda istatistiksel olarak anlamlı ve pozitif olduğu gözlenmiştir. Diğer bir
ifade ile ilk yıllardan itibaren benzer firmaların listeye girdiği bilgisi
ışığında, ilerleyen yıllarda marka değeri sıralamasında ilk 10’a girmesi
muhtemel hisse senetlerine yatırım yaparak normalüstü getiri elde etme
olasılığı azalmıştır. Bu durumun bilginin zaman geçtikçe fiyatlara yansıtılmış
olmasından kaynaklandığı ileri sürülebilir.
Cancer vaccine adjuvants
Authors: Baryshnikova M. A. , Kosorukov V. S.
Published: January 2019

Adjuvants are important components of cancer vaccines because they enhance immune responses to vaccination. However, adjuvants licensed for clinical use, e. g. aluminum salts, fail to stimulate an effective immune response. Research and development of new adjuvants with combined functions, including immune stimulation and antigen delivery, are a vital task for antitumor immunotherapy. Clinical trials of immune stimulating compounds, in particular Toll-like receptor (TLR) ligands, reveal their therapeutic potential as both antitumor agents and vaccine adjuvants.
