La dimensión espacial del suicidio y su vínculo con el mercado laboral mexicano (2000-2004)
Authors: Jasso Vargas Rosalba 
Published: November 2015

<p>A principios del siglo XXI en México se ha puesto de manifiesto en la opinión pública la preocupación respecto al ascenso de muertes por la causa de suicidio y de su posible vínculo con malas condiciones laborales. El objetivo principal del trabajo es comprobar si las tasas de suicidio son una respuesta a malas condiciones laborales. Para este propósito, partiendo de una perspectiva espacial, se buscó evidenciar el comportamiento heterogéneo del fenómeno del suicidio a través del territorio mexicano, verificar la existencia de “regiones” en el espacio de tasas de suicidio y comprobar si las tasas de suicidio son una respuesta a las características económicas, demográficas y sociales de los municipios de la República Mexicana en particular a las laborales. El trabajo encuentra que no existen las evidencias estadísticas suficientes para probar que malas condiciones laborales estén provocando un incremento en la incidencia del suicidio. Adicionalmente, se hace visible que las cifras nacionales y estatales no reconocen comportamientos regionales importantes.</p>
Una aproximación al campo de estudio del pensamiento estratégico desde las publicaciones académicas: de lo predecible a lo emergente
Authors: López López Paula Andrea 
Published: November 2015

<p>En las última dos décadas, diversos autores del management han realizado un llamado a reflexionar sobre el paradigma dominante en el campo de estudio de la estrategia. Las críticas se han centrado en el enfoque determinístico con el que se ha tratado el problema estratégico, planteando la necesidad de cuestionar el modelo racional-mecanicista imperante y de proponer nuevos postulados que sean congruentes con las condiciones actuales del mundo de las organizaciones. En ese sentido, el presente artículo es una revisión bibliográfica sistemática que pretende, no solo señalar, los elementos que configuran el pensamiento estratégico en los últimos años, sino que a su vez reconocer las características de la perspectiva emergente que se ha ido consolidando en el campo.</p>

Creative industries and their relation to translation/interpreting practice and to innovation
Authors: Vesela Dagmar , Klimova Katarina 
Published: November 2015

As an economic sector, creative industries include all human activities associated with creativity, and they comprise a modern phenomenon which contributes significantly to the sustainment of economic growth and employment in a world afflicted by the financial and economic crisis. It is for these reasons that they have become a part of the EU agenda, where they are seen as connected to the cultural industries (CCI). Discussions focused on the creative economy are increasingly included in legislatorsâ€™ speeches and EU working and legislative materials filled with the new terminology of this field. The philosophy of creative industries and of the creative economy has its origins in the Anglophone world and this is also reflected in the key CCI terminology. As intercultural and interlingual mediators, interpreters and translators are confronted with this fact in their work and offer information to the intended recipient in the language of the target culture. In the EUâ€™s case, this means more than 20 working languages. In this paper, weÂ focus on two of them â€“ Slovak, French â€“ and we will point out the specifics of translation of borrowed lexical units (Anglicisms). We also briefly describe the efforts to establish an innovative university programme focused on the multilingual processing of information.Â Keywords: Creative industries, Terminology, Multidisciplinary Education, Innovation.

Automated detection of optic disc in retinal fundus images using gabor filter kernels
Authors: Sen Baha , Akyol Kemal , Bayir Safak , Kaya Hilal 
Published: November 2015

Identifying the position of the optic disc on the retinal fundus image is a technique that is often used in medical diagnosis, treatment and monitoring processes. Determination of the intensity of the bright colors that belongs to the optic disc on a normal retinal image by the help of image processing algorithms is a fairly easy process. However, determining the optic disc on a retinal image including the diabetic retinopathy disease is a more difficult process. The reason for this difficulty is the existence of many regions that have the same light intensity in different parts of the retina. In this study, a new method for supplying the automatic determination of the optic disc in a recursive manner is proposed. By the help of OpenCV library, automatic determination process of the optic disc on the retinal fundus images including the diabetic retinopathy disease, has been implemented. Circular regions with maximum brightness values in the retinal images that were normalized and passed through the denoising process were determined and these regions were analyzed if they are optic disc or not. This process basically consists of two steps: In the first step, the possible optic disc candidate regions were determined recursively and in the second step, by the help of Gabor filter kernels, these regions were analyzed and itâ€™s provided to decide if they are optic disc or not. This study is based on a dataset that has 89 images including diabetic retinopathy disease. Performance of this system is tested on these images and also on the images that the red, green, blue color channels and Contrast Limited Adaptive Histogram Equalization (CLAHE) retinas were obtained. Most accurate determination of the position of the optic disc is obtained with retinas, implemented process CLAHE, including the best success rate of 89.88%.Â Keywords: Optic disc, diabetic retinopathy, recursively, circular region, gabor filter kernels.

Published: November 2015

This research aims to determine the self-efficacy and success levels of teaching candidates on developing multimedia to the Docebo learning management system through integrating various online tools in developing multimedia courses and using this method in a project-based learning process. Second year students from the department of Computer Education and Educational Technology participated in this research. Random selection method was used in order to assign the students to the groups. Online (30 participants) and blended (30 participants) groups were constituted for this experimental study. Based on the pre-test results of the students participating in the study, it was investigated as to whether there was a difference between the groups. Since pre-test success scores of the students from the two groups would affect the results of the research, the difference between the two groups was examined by applying a t-test. There was no significant differenceÂ in the pre-test scores of the teaching candidates in the group. Data from the research were collected with demographic information forms and 5-point Likert-type scale developed by authors.Â Keywords: multimedia designing, teacher candidates, internet based learning, learning management systems, online learning.Â Â

Authors: Uzunboylu Huseyin , Karagozlu Damla 
Published: November 2015

The use of learning technologies, especially multimedia provide varied facilities for studentsâ€™ learning that are not possible with other media. Pedagogical literature has proved that individuals have different learning styles. Flipped classroom is a pedagogical approach which means that activities that have traditionally taken place inside the classroom take place outside the classroom and vice versa. The flipped classroom environment ensures that students become more active participants compared with in the traditional classroom. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of the flipped classroom approach in education. The contribution of the flipped classroom to education is discussed in relation to the changes in students' and instructors' role. Subsequently, flipped classroom applications in various disciplines of education are illustrated. The recommendations made in the literature for design specifications that integrate flipped classrooms with technology are discussed. The paper concludes that a careful consideration of the warnings and recommendations made in the literature can help to produce effective flipped classroom environments and also this paper attempts to inform those who are thinking of using new technologies and approaches to deliver courses.Â Keywords: flipped classroom, inverted classroom, blended learning, active learning.

Authors: Prahardini P.E.R. 
Published: November 2015

Lumajang regency is one of the banana production centre in East Java having high- diversity of banana germ plasm. There are 33 cultivars of banana germ plasm in the regency, consist of eaten ripe and plantain. One of uniqe plantain used as the symbol of Lumajang regency is plantain Agung Semeru variety, the local superior variety of this regency. This variety can grow well at 450 – 650 m above sea level. The uniqueness of banana Agung Semeru variety can be seen by the number of sucker per cluster (only 1 – 2 suckers per cluster), the size of the finger (33 – 36 cm long and 19 cm around) and the number of hand per bunch (only 1 – 2 hand per bunch). Other characteristics of the variety are the thickness of fruit skin, the long period of fruit storage (3 – 4 weeks after harvesting) and the sweetness of fruit flesh. Even though the skin changes from yellow to black, the flesh still can be consumed, because it doesn’t become soft. This variety also resistant to the Sigatoka disease compared to other plantain cultivars.

Symptomatic large or giant capillary telangiectasias: management and outcome in 5 cases
Authors: Yu Tao , Sun Xingwen , You Yan , Chen Jie , Wang Jun-mei , Wang Shuo , Lin Ning , Liang Buqing , Zhao Jizong 
Published: November 2015

Brain capillary telangiectasias (BCTs) are usually small and benign with a predilection in the pons and basal ganglion. Reports of large and symptomatic BCTs are rare. Large BCTs have a much higher risk of causing uncontrolled bleeding and severe neurological defects, and they can be fatal if left untreated. Therefore, large BCTs should be managed with special caution. Because of the lack of reports, diagnosis of large BCTs has been difficult. Strategies of management are undefined for large or giant BCTs.
The current study presents 5 cases of giant and large BCTs. To the authors’ knowledge, this is the largest series of this disease ever reported. Radiological findings, histopathological characteristics, clinical presentations, and surgical management were analyzed in 5 symptomatic, unusually large BCTs (mean diameter 5.06 cm, range 1.8–8 cm).
Four patients presented with focal or generalized seizures, and 1 patient presented with transient vision loss attributed to the lesions. Gross-total resection of the lesion was achieved in all patients. After surgery, the 4 patients with seizures were symptom free for follow-up periods varying from more than 1 to 5 years with no additional neurological deficits.
The unique location, radiological characteristics, and clinical course suggest that giant BCTs could be a different entity from small BCTs. Surgery might be a good option for treatment of patients with intractable neurological symptoms, especially in those with surgically accessible locations. Complete removal would be anticipated to provide relief of the symptoms without causing new neurological deficits.
Association of apolipoprotein E gene polymorphism with small-vessel lesions and stroke type in moyamoya disease: a preliminary study
Authors: Jang Dong-Kyu , Huh Pil Woo , Lee Kwan-Sung 
Published: November 2015

OBJECT
The present study was conducted to investigate whether microbleeds or microinfarcts are associated with apolipoprotein E (APOE) gene polymorphisms in patients with moyamoya disease (MMD), and if so, whetherAPOE gene polymorphisms are also associated with stroke type in patients with MMD.

METHODS
This cross-sectional, multicenter study included 86 consecutive patients with MMD who underwent T2*-weighted gradient echo or susceptibility-weighted MR imaging and 83 healthy control volunteers. Baseline clinical and radiological characteristics were recorded at diagnosis, and inter- and intragroup differences in the APOE genotypes were assessed. Multivariate binary logistic regression models were used to determine the association factors for small-vessel lesions (SVLs) and hemorrhagic presentation in patients with MMD.

RESULTS
There was no difference in APOE gene polymorphism and the incidence of SVLs between patients with MMD and healthy controls (p > 0.05). In the MMD group, 7 (8.1%) patients had microbleeds and 32 (37.2%) patients had microinfarcts. Microbleeds were more frequently identified in patients with hemorrhagic-type than in nonhemorrhagictype MMD (p = 0.003). APOE genotypes differed according to the presence of microbleeds (p = 0.024). APOE ε2 or ε4 carriers also experienced microbleeds more frequently than APOE ε3/ε3 carriers (p = 0.013). In the multivariate regression analysis in patients with MMD, microbleeds were significantly related to APOE ε2 or ε4 carrier status (OR 7.86; 95% CI1.20–51.62; p = 0.032) and cerebral aneurysm (OR 17.31; 95% CI 2.09–143.57; p = 0.008). Microinfarcts were independently associated with hypertension (OR 3.01; 95% CI 1.05–7.86; p = 0.007). Hemorrhagic presentation was markedly associated with microbleeds (OR 10.63; 95% CI 1.11–102.0; p = 0.041).

CONCLUSIONS
These preliminary results did not show a difference in APOE gene polymorphisms between patients with MMD and healthy persons. However, they imply that APOE gene polymorphisms may play certain roles in the presence of microbleeds but not microinfarcts in patients with MMD. A further confirmatory study is necessary to elucidate the effect of APOE gene polymorphisms and SVLs on the future incidence of stroke in patients with MMD.
Increasing numbers of nonaneurysmal subarachnoid hemorrhage in the last 15 years: antithrombotic medication as reason and prognostic factor?

Published: November 2015

OBJECT
Subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial aneurysm, but in some patients no source of hemorrhage can be detected. More recent data showed increasing numbers of cases of spontaneous nonaneurysmal SAH (NASAH). The aim of this study was to analyze factors, especially the use of antithrombotic medications such as systemic anticoagulation or antiplatelet agents (aCPs), influencing the increasing numbers of cases of NASAH and the clinical outcome.

METHODS
Between 1999 and 2013, 214 patients who were admitted to the authors’ institution suffered from NASAH, 14% of all patients with SAH. Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months. Risk factors were identified based on the outcome.

RESULTS
The number of patients with NASAH increased significantly in the last 15 years of the study period. There was a statistically significant increase in the rate of nonperimesencephalic (NPM)-SAH occurrence and aCP use, while the proportion of elderly patients remained stable. Favorable outcome (mRS 0–2) was achieved in 85% of cases, but patients treated with aCPs had a significantly higher risk for an unfavorable outcome. Further analysis showed that elderly patients, and especially the subgroup with a Fisher Grade 3 bleeding pattern, had a high risk for an unfavorable outcome, whereas the subgroup of NPM-SAH without a Fisher Grade 3 bleeding pattern had a favorable outcome, similar to perimesencephalic (PM)-SAH.

CONCLUSIONS
Over the years, a significant increase in the number of patients with NASAH has been observed. Also, the rate of aCP use has increased significantly. Risk factors for an unfavorable outcome were age > 65 years, Fisher Grade 3 bleeding pattern, and aCP use. Both “PM-SAH” and “NPM-SAH without a Fisher Grade 3 bleeding pattern” had excellent outcomes. Patients with NASAH and a Fisher Grade 3 bleeding pattern had a significantly higher risk for an unfavorable outcome and death. Therefore, for further investigations, NPM-SAH should be stratified into patients with or without a Fisher Grade 3 bleeding pattern. Also, cases of spontaneous SAH should be stratified into NASAH and aneurysmal SAH.
Orbit-associated tumors: navigation and control of resection using intraoperative computed tomography
Authors: Terpolilli Nicole A. , Rachinger Walter , Kunz Mathias , Thon Niklas , Flatz Wilhelm H. , Tonn Jörg-Christian , Schichor Christian 
Published: November 2015

OBJECT
Treatment of skull base lesions is complex and usually requires a multidisciplinary approach. In meningioma, which is the most common tumor entity in this region, resection is considered to be the most important therapeutic step to avoid tumor recurrence. However, resection of skull base lesions with orbital or optic nerve involvement poses a challenge due to their anatomical structure and their proximity to eloquent areas. Therefore the main goal of surgery should be to achieve the maximum extent of resection while preserving neurological function. In the postoperative course, medical and radiotherapeutic strategies may then be successfully used to treat possible tumor residues. Methods to safely improve the extent of resection in skull base lesions therefore are desirable. The current study reports the authors’ experience with the use of intraoperative CT (iCT) combined with neuronavigation with regard to feasibility and possible benefits of the method.

METHODS
Those patients with tumorous lesions in relationship to the orbit, sphenoid wing, or cavernous sinus who were surgically treated between October 2008 and December 2013 using iCT-based neuronavigation and in whom an intraoperative scan was obtained for control of resection were included. In all cases a second iCT scan was performed under sterile conditions after completion of navigation-guided microsurgical tumor resection. The surgical strategy was adapted accordingly; if necessary, resection was continued.

RESULTS
Twenty-three patients (19 with WHO Grade I meningioma and 4 with other lesions) were included. The most common clinical symptoms were loss of visual acuity and exophthalmus. Intraoperative control of resection by iCT was successfully obtained in all cases. Intraoperative imaging changed the surgical approach in more than half (52.2%) of these patients, either because iCT demonstrated unexpected residual tumor masses or because the second scan revealed additional tumor tissue that was not detected in the first scan due to overlay by osseous tumor parts; in these cases resection was continued. In the remaining cases resection was concluded as planned because iCT verified the surgeon’s microscopic estimation of tumor resection status. Postoperative visual outcome was favorable in more than 80% of patients.

CONCLUSIONS
Intraoperative CT allows control of resection in case of uncertainty and can help to improve the extent of maximal safe resection, especially in case of osseous tumor parts and masses within the orbit.
