Authors: Russell Jake , Griffith Tia , Naghipour Saba , Vider Jelena , Du Toit Eugene , Patel Hemal , Peart Jason , Headrick John
Published: September 2020

Whether dietary omega-3 (n-3) polyunsaturated fatty acid (PUFA) confers cardiac benefit in cardiometabolic disorders is unclear. We test whether dietary α-linolenic acid (ALA) enhances myocardial resistance to ischemia-reperfusion (I-R) and responses to ischemic preconditioning (IPC) in type 2 diabetes (T2D); and involvement of conventional PUFA-dependent mechanisms (caveolins/cavins, kinase signaling, mitochondrial function, and inflammation). Eight-week male C57Bl/6 mice received streptozotocin (75 mg/kg) and 21 weeks high-fat/high-carbohydrate feeding. Half received ALA over six weeks. Responses to I-R/IPC were assessed in perfused hearts. Localization and expression of caveolins/cavins, protein kinase B (AKT), and glycogen synthase kinase-3β (GSK3β); mitochondrial function; and inflammatory mediators were assessed. ALA reduced circulating leptin, without affecting body weight, glycemic dysfunction, or cholesterol. While I-R tolerance was unaltered, paradoxical injury with IPC was reversed to cardioprotection with ALA. However, post-ischemic apoptosis (nucleosome content) appeared unchanged. Benefit was not associated with shifts in localization or expression of caveolins/cavins, p-AKT, p-GSK3β, or mitochondrial function. Despite mixed inflammatory mediator changes, tumor necrosis factor-a (TNF-a) was markedly reduced. Data collectively reveal a novel impact of ALA on cardioprotective dysfunction in T2D mice, unrelated to caveolins/cavins, mitochondrial, or stress kinase modulation. Although evidence suggests inflammatory involvement, the basis of this “un-conventional” protection remains to be identified.

Published: September 2020

In the face of the obesity epidemic around the world, attention should be focused on the role of maternal obesity in the development of pregnancy. The purpose of this analysis was to evaluate the prediction of preeclampsia (PE) and isolated gestational hypertension (GH) for a number of maternal factors, in order to investigate the importance of pre-pregnancy obesity (body mass index, BMI ≥ 30 kg/m2), compared to other risk factors (e.g., prior PE, pregnancy weight gain (GWG), infertility treatment, interpregnancy interval, family history, the lack of vitamin supplementation, urogenital infection, and socioeconomic factors). In total, 912 women without chronic diseases were examined in a Polish prospective cohort of women with a single pregnancy (recruited in 2015–2016). Separate analyses were performed for the women who developed GH (n = 113) vs. 775 women who remained normotensive, as well as for those who developed PE (n = 24) vs. 775 controls. The probability of each disease was assessed for the base prediction model (age + primiparity) and for the model extended by one (test) variable, using logistic regression. Three measures were used to assess the prediction: area under curve (AUC) of the base and extended model, integrated discrimination improvement (IDI) (the index shows the difference between the value of the mean change in the predicted probability between the group of sick and healthy women when a new factor is added to the model), and net reclassification improvement (NRI) (the index focuses on the reclassification table describing the number of women in whom an upward or downward shift in the disease probability value occurred after a new factor had been added, including results for healthy and sick women). In the GH prediction, AUC increased most strongly when we added BMI (kg/m2) as a continuous variable (AUC = 0.716, p < 0.001) to the base model. The highest IDI index was obtained for prior GH/PE (IDI = 0.068, p < 0.001). The addition of BMI as a continuous variable or BMI ≥ 25 kg/m2 improved the classification for healthy and sick women the most (NRI = 0.571, p < 0.001). In the PE prediction, AUC increased most strongly when we added BMI categories (AUC = 0.726, p < 0.001) to the base model. The highest IDI index was obtained for prior GH/PE (IDI = 0.050, p = 0.080). The addition of BMI categories improved the classification for healthy and sick women the most (NRI = 0.688; p = 0.001). After summing up the results of three indexes, the probability of hypertension in pregnancy was most strongly improved by BMI, including BMI ≥ 25 kg/m2 for the GH prediction, and BMI ≥ 30 kg/m2 for the PE prediction. Main conclusions: Pre-pregnancy BMI was the most likely factor to increase the probability of developing hypertension in pregnancy, compared to other risk factors. Hierarchies of PE and GH risk factors may suggest different (or common) mechanisms of their development.

Published: September 2020

Combination therapy is considered to be a promising strategy for improving the therapeutic efficiency of cancer treatment. In this study, an on-demand pH-sensitive nanocluster (NC) system was prepared by the encapsulation of gold nanorods (AuNR) and doxorubicin (DOX) by a pH-sensitive polymer, poly(aspartic acid-graft-imidazole)-PEG, to enhance the therapeutic effect of chemotherapy and photothermal therapy. At pH 6.5, the NC systems formed aggregated structures and released higher drug amounts while sustaining a stable nano-assembly, structured with less systemic toxicity at pH 7.4. The NC could also increase antitumor efficacy as a result of improved accumulation and release of DOX from the NC system at pHex and pHen with locally applied near-infrared light. Therefore, an NC system would be a potent strategy for on-demand combination treatment to target tumors with less systemic toxicity and an improved therapeutic effect.
Pharmacists’ Prescribing in Saudi Arabia: Cross-Sectional Study Describing Current Practices and Future Perspectives
Authors: Ajabnoor Alyaa M. , Cooper Richard J.
Published: September 2020

Pharmacist prescribing is being increasingly undertaken to better use their skills and reduce the workload of existing prescribers such as doctors, often using formal processes to legitimate these activities. In developing countries like Saudi Arabia, however, pharmacists’ prescribing remains informal with no legislation or formal training and there is a lack of research and understanding into such practices. Therefore, we aimed to describe current pharmacist prescribing practices in Saudi Arabia and explore pharmacists’ views about pharmacists’ prescribing. This is a cross-sectional survey study using an online questionnaire of hospital pharmacists in Saudi Arabia about pharmacists’ prescribing, and associated views about prescribing legislation and barriers to implementing pharmacist prescribing. Over a quarter (28.5%) of pharmacists reported themselves as prescribers, 49% were following a collaborative prescribing model, 18% independent prescribing, and 33% were doing both. Ninety percent of prescribers reported confidence in prescribing the appropriate treatment and 92.3% perceived they will benefit from more prescribing training. Healthcare practice culture and pharmacist’s competency were identified as barriers. There is an overall support for pharmacists’ prescribing in Saudi Arabia among this sample of hospital pharmacists, with limitations in resources and the absence of standardized prescribing training being perceived as key barriers to pharmacists’ prescribing.
Scale-Up of Self-Regenerating Semi-Batch Adsorption Cycles through Concurrent Adsorption and Reduction of Cr(VI) on Sheep Wool
Authors: Badrelzaman Mohamed , Khamis Mustafa I. , Ibrahim Taleb H. , Jumean Fawwaz H.
Published: September 2020

A previous publication by our group reported that adsorption of Cr(VI) on sheep wool reached 99% when allowed a long residence time, with concurrent reduction to Cr(III). In this study, the process was scaled up by optimizing a pilot plant based on semi-batch adsorption cycles. This yielded Cr(III), which is about 300 times less toxic than Cr(VI), and can be precipitated using lime at high pH. Since the reduction step is slower than the adsorption one, an adsorption column was designed to perform semi-batch operation cycles, whereby the extended “off cycle” allows reduction to take place. Since reduction of Cr(VI) frees active sites on wool, the plant acts in lieu of in situ regeneration, accompanied by additional adsorption of Cr(VI). The results show that 97% of the column efficiency can be recovered within 24 h of “off cycle”. Wastewater from a local electroplating industry was treated by this method with high removal of Cr(VI), reaching the limit permitted by environmental standards. This study also reveals that typical concentrations of heavy metals, present in wastewater produced from electroplating, had no substantial antagonistic interference with Cr(VI) adsorption.
Load Position and Weight Classification during Carrying Gait Using Wearable Inertial and Electromyographic Sensors
Authors: Goršič Maja , Dai Boyi , Novak Domen
Published: September 2020

Lifting and carrying heavy objects is a major aspect of physically intensive jobs. Wearable sensors have previously been used to classify different ways of picking up an object, but have seen only limited use for automatic classification of load position and weight while a person is walking and carrying an object. In this proof-of-concept study, we thus used wearable inertial and electromyographic sensors for offline classification of different load positions (frontal vs. unilateral vs. bilateral side loads) and weights during gait. Ten participants performed 19 different carrying trials each while wearing the sensors, and data from these trials were used to train and evaluate classification algorithms based on supervised machine learning. The algorithms differentiated between frontal and other loads (side/none) with an accuracy of 100%, between frontal vs. unilateral side load vs. bilateral side load with an accuracy of 96.1%, and between different load asymmetry levels with accuracies of 75–79%. While the study is limited by a lack of electromyographic sensors on the arms and a limited number of load positions/weights, it shows that wearable sensors can differentiate between different load positions and weights during gait with high accuracy. In the future, such approaches could be used to control assistive devices or for long-term worker monitoring in physically demanding occupations.
An Integrated Multi-Sensor Network for Adaptive Grasping of Fragile Fruits: Design and Feasibility Tests
Authors: Xie Yuanxin , Zhang Baohua , Zhou Jun , Bai Yuhao , Zhang Meng
Published: September 2020

Secure grasping of fragile fruits and other agricultural products without potential slip and damage is still a challenge due to the size and shape varying, bruise susceptible, as well as hardness changing during fruit and vegetable maturation. In the robotic grasping process, the mechanical damage mainly depends upon the aggressiveness of the gripper and the sensitivity of the product to the damage. In this study, a flexible gripper integrated with multi-sensor network is designed and tested. The network proposed includes three kinds of sensors that enable the gripper to grasp various products with the sense of touch and visual perception. Particular attention has been attached to the sensors applied between the fingers, and this makes sensing and grasping capabilities improved. To create an accurate grasping system, a grasping algorithm and the force control model are proposed for any bending state based on Cosserat theory. The boundary detection is included in the grasping algorithm, detecting the shape edge by some certain point calculation. The created grasping system guarantees mechanical compliance by evaluating and adjusting the finger status including force, angle, and direction. Multi-group tests have been done on grasping several objects of different sizes and materials in daily life. The relationship between force, bending, and surface material is also analyzed and compared under different conditions. The numerical comparisons related to the measurement error are analyzed based on their standard deviations. Experimental results indicate that this flexible manipulator with proposed system and strategy has better grasping ability for fragile fruits with its good flexibility and dexterity.
CNN with Pose Segmentation for Suspicious Object Detection in MMW Security Images
Authors: Meng Zhichao , Zhang Man , Wang Hongxian
Published: September 2020

Millimeter-wave (MMW) imaging scanners can see through clothing to form a three-dimensional holographic image of the human body and suspicious objects, providing a harmless alternative for non-contacting searches in security check. Suspicious object detection in MMW images is challenging, since most of them are small, reflection-weak, shape, and reflection-diverse. Conventional detectors with artificial neural networks, like convolution neural network (CNN), usually take the problem of finding suspicious objects as an object recognition task, yielding difficulties in developing large-amount and complete sample sets of objects. In this paper, a new algorithm is developed using the human pose segmentation followed by the deep CNN detection. The algorithm is emphasized to learn the similarity with humans’ body clutter applied to training corresponding CNNs after the image segmentation base of the pose estimation. Moreover, the suspicious object recognition in the MMW image is converted to a binary classification task. Instead of recognizing all sorts of suspicious objects, the CNN detector determines whether the body part images present the abnormal patterns containing suspicious objects. The proposed algorithm that is based on CNN with the pose segmentation has concise configuration, but optimal performance in the suspicious object detection. Extensive experiments confirm the effectiveness and superiority of the proposal.
Active Learning Plus Deep Learning Can Establish Cost-Effective and Robust Model for Multichannel Image: A Case on Hyperspectral Image Classification
Authors: Shi Fangyu , Wang Zhaodi , Hu Menghan , Zhai Guangtao
Published: September 2020

Relying on large scale labeled datasets, deep learning has achieved good performance in image classification tasks. In agricultural and biological engineering, image annotation is time-consuming and expensive. It also requires annotators to have technical skills in specific areas. Obtaining the ground truth is difficult because natural images are expensive. In addition, images in these areas are usually stored as multichannel images, such as computed tomography (CT) images, magnetic resonance images (MRI), and hyperspectral images (HSI). In this paper, we present a framework using active learning and deep learning for multichannel image classification. We use three active learning algorithms, including least confidence, margin sampling, and entropy, as the selection criteria. Based on this framework, we further introduce an “image pool” to make full advantage of images generated by data augmentation. To prove the availability of the proposed framework, we present a case study on agricultural hyperspectral image classification. The results show that the proposed framework achieves better performance compared with the deep learning model. Manual annotation of all the training sets achieves an encouraging accuracy. In comparison, using active learning algorithm of entropy and image pool achieves a similar accuracy with only part of the whole training set manually annotated. In practical application, the proposed framework can remarkably reduce labeling effort during the model development and upadting processes, and can be applied to multichannel image classification in agricultural and biological engineering.
An Ore Image Segmentation Method Based on RDU-Net Model
Authors: Xiao Dong , Liu Xiwen , Le Ba Tuan , Ji Zhiwen , Sun Xiaoyu
Published: September 2020

The ore fragment size on the conveyor belt of concentrators is not only the main index to verify the crushing process, but also affects the production efficiency, operation cost and even production safety of the mine. In order to get the size of ore fragments on the conveyor belt, the image segmentation method is a convenient and fast choice. However, due to the influence of dust, light and uneven color and texture, the traditional ore image segmentation methods are prone to oversegmentation and undersegmentation. In order to solve these problems, this paper proposes an ore image segmentation model called RDU-Net (R: residual connection; DU: DUNet), which combines the residual structure of convolutional neural network with DUNet model, greatly improving the accuracy of image segmentation. RDU-Net can adaptively adjust the receptive field according to the size and shape of different ore fragments, capture the ore edge of different shape and size, and realize the accurate segmentation of ore image. The experimental results show that compared with other U-Net and DUNet, the RDU-Net has significantly improved segmentation accuracy, and has better generalization ability, which can fully meet the requirements of ore fragment size detection in the concentrator.
Analysis of the Impact of the Use Profile of HVAC Systems Established by the Spanish Standard to Assess Residential Building Energy Performance
Authors: Bienvenido-Huertas David
Published: September 2020

State regulations play an important role to guarantee an appropriate building energy performance. As for the Spanish regulation, the limitation of energy consumption should be analyzed with simulation tools by using operational profiles. The profile of operational conditions of HVAC systems in residential buildings limits the use of heating and cooling systems. This paper studied the limitations of the residential profile in energy assessment processes through simulation tools. A case study was analyzed with three operational approaches and was placed in 8131 Spanish cities. The results showed that the use limitations of cooling systems lead to ignorance of an important percentage contribution in the cooling energy demand in some months of the year. The use of an operational profile with an extended calendar for cooling systems for the entire year would imply a more appropriate knowledge of the building energy performance in order to know the fulfilment of the state regulation and its correct energy classification.

Published: September 2020

In the face of the socio-environmental crisis in which we are immersed, the initial training of teachers must assume the work in favor of a critical, committed, participatory citizenry capable of responding to the socio-environmental problems of the current and future world. The analysis of the initial 61 research projects on socio-environmental problems of four classes involving 240 students of the Degree in Early Childhood Education at the University of Seville (Seville, Spain) is presented. Under an interpretive descriptive approach according to a category system based on the Sustainable Development Goals (SDGs) established by the UN (2015) and its targets, we can learn about their socio-environmental concerns and how they relate to the current 2030 Agenda. We obtain that of the 17 SDGs, around half of the final 42 research projects analyzed focus on sustainable consumption and project patterns and climate change, while problems related to poverty, hunger, or peace do not arise. In addition to allowing us to draw a portrait of the socio-environmental concerns of early childhood preservice teachers, the data obtained also gave us the opportunity to ponder the didactic possibilities that these types of formative activities bring to the training of teachers who are critical and committed to transforming the world.

Published: September 2020

This study aimed to investigate the impact of hotel employees’ perceived job embeddedness on job satisfaction, self-efficacy, turnover intention, job performance, and job commitment. The results showed that job embeddedness partially increased job satisfaction, while job satisfaction and self-efficacy reduced turnover intention and increased job performance and job commitment. Furthermore, job satisfaction and self-efficacy were found to play an important mediating role. Therefore, the theoretical framework, based on the results of this study, clearly demonstrated the causal relationship between the given variables, and adequately describes the goals of this study. The theoretical/practical implications are discussed in detail in the conclusion.

Published: September 2020

The relationships between community-weighted mean (CWM) functional traits and ecosystem functions have been extensively studied. However, how CWM traits and ecosystem functions respond to grazing types and whether the relationships between CWM traits and ecosystem functions mediate the response of ecosystem functions to grazing types remains controversial. In the present study, we set up a seven-year grazing experiment with four grazing types: no grazing (NG), cattle grazing (CG), sheep grazing (SG), and mixed grazing by sheep and cattle (MG) on Inner Mongolia grassland. Nine functional traits of dominant species and five ecosystem functions under different grazing types were determined, and the relationships between CWM traits and ecosystem functions were analyzed. The results showed that the CWM height decreased after grazing, while the CWM nitrogen and phosphorus contents increased after CG. SG caused a greater decrease in aboveground biomass (AGB) and a greater increase in the net ecosystem CO2 exchange (NEE) of grassland ecosystems than did CG. This result may be partially because the CWM nutrient content and NEE were more negatively related after CG; and the increase in the CWM nitrogen and phosphorus contents suppressed NEE after CG. Therefore, to protect the sustainability of grassland ecosystem functions, SG should be reduced. Additionally, our work emphasizes that the relationships between plant functional traits and ecosystem functions may mediate the response of ecosystem functions to grazing types.
Key Parameters Featuring BIM-LCA Integration in Buildings: A Practical Review of the Current Trends
Authors: Dalla Mora Tiziano , Bolzonello Erika , Cavalliere Carmine , Peron Fabio
Published: September 2020

The construction sector is responsible for 40% of carbon emissions, 14% of water consumption and 60% of waste production in the world, generating a state of unsustainability. In order to keep these values under control and make the most sustainable choices starting from the earliest stages of building design, a Life Cycle Assessment (LCA) can be used. This consists of an analysis of the environmental impacts of a product, activity or process throughout all phases of the life cycle. The fundamental problem of implementing this analysis process in the construction sector is the difficulty in managing the fragmented building information that covers all aspects of buildings life stages in an integrated way. The Building Information Modeling (BIM) approach offers the possibility of managing a complex information system in an integrated manner. The BIM-LCA integration solutions proposed in recent years made LCA analysis faster, cheaper and usable by more professionals. This paper proposes an analysis of the state of the art of the research published in the last ten years regarding the integration of BIM-LCA as a methodology whereby the BIM approach can support and simplify data management for LCA analysis. The aim was to present the work methodologies tested so far and to describe all the factors that were considered in applying the BIM-LCA integration. The novelty of this review consists of identifying a series of more recurrent parameters and measures used by most researchers deriving a trend of possible and consolidated workflows. The result is, therefore, to present evidence of a general heterogenous framework and to define the common and widespread approaches identifying the main features.

Hematophagous arthropods are important vectors for zoonotic pathogens. To date, a huge number of viruses have been identified in these arthropods, with a considerable proportion of them being human pathogens. However, the viromes of hematophagous arthropods are still largely unresearched. In this study, a number of arthropods were collected from Belgrade, Serbia including mosquitoes, ticks and bedbugs. The viromes of these arthropods were identified and characterized using Illumina MiSeq sequencing. In total, 21 viruses belonging to 11 families were characterized, with 11 of them representing novel species. These results may contribute to our knowledge of RNA viruses in arthropods and the discovery of novel human pathogens.

Authors: Al-Saffar Mohammed N , Hayhoe Benedict WJ , Harris Matthew J , Majeed Azeem , Greenfield Geva
Published: September 2020

Background

Frequent paediatric attendances make up a large proportion of a GP's workload. Currently, there is no systematic review on frequent paediatric attendances in primary care.

Aim

To identify the sociodemographic and clinical characteristics of children who attend primary care frequently.

Design & setting

A systematic review.

Method

The electronic databases MEDLINE, Embase, and PsycINFO were searched up to January 2020, using terms relating to frequent attendance in primary care settings. Studies were eligible if they considered children frequently attending in primary care (aged 0–19 years). Relevant data were extracted and analysed by narrative synthesis.

Results

Six studies, of fair quality overall, were included in the review. Frequent attendance was associated with presence of psychosocial and mental health problems, younger age, school absence, presence of chronic conditions, and high level of anxiety in their parents.

Conclusion

Various sociodemographic and medical characteristics of children were associated with frequent attendance in primary care. Research on interventions needs to account for the social context and community characteristics. Integrating GP services with mental health and social care could potentially provide a response to medical and psychosocial needs of frequently attending children and their families.

Background

Tonsillectomy may treat IgA nephropathy (IgAN) by reducing the levels of galactose-deficient IgA1. Therefore, we aimed to analyze the long-term effects of tonsillectomy on patients with IgAN, as an initial treatment and as a treatment at any time in their lives.

Methods

In this retrospective cohort analysis, 1147 patients with IgAN were grouped according to whether they had undergone tonsillectomy at any time, >1 year after renal biopsy (study 1), or within 1 year after renal biopsy (study 2). The patients were propensity-score matched or divided into four groups according to their proteinuria and renal function. The 20-year renal survival rates were evaluated until serum creatinine levels doubled (primary end point) and ESKD occurred (secondary end point).

Results

Patients in both studies had similar background characteristics after propensity score matching. In study 1, the renal survival rates for the primary and secondary end points were significantly higher for patients who underwent tonsillectomy at any time or >1 year after renal biopsy compared with those who did not. In study 2, the renal survival rates for the primary and secondary end points were significantly higher for patients who underwent tonsillectomy soon after renal biopsy compared with those who did not (primary end point, 98% versus 69%, P=0.001; secondary end point, 100% versus 75%, P=0.0001). A stratified analysis showed that significant treatment efficacy was observed for patients with proteinuria >1.0 g/d. Multivariate Cox regression analyses showed that tonsillectomy was associated with disease progression (hazard ratio, 0.27; P=0.04). Complications associated with tonsillectomy occurred in 8% of patients.

Conclusions

Among patients with IgAN, tonsillectomy at any time of life, or soon after renal biopsy, prevents disease progression, and the procedure is relatively safe.
Orhan Kemal'in Hayatını Otobiyografik Romanlarından Okumak
Authors: ÖZAYDIN YAKIŞTIRAN Burcu
Published: September 2020

Birçok yazarın yazı hayatına kendinden, yaşanmışlıklarından yola çıkarak başladığını söylemek mümkündür. Orhan Kemal’in severek okuduğu ve örnek aldığı Panait Istrati ve Maksim Gorki, romanlarında sıklıkla kendi hayatlarından esinlenmişlerdir. Benzer biçimde Orhan Kemal de ilk romanlarına "Küçük Adamın Notları" başlığıyla yaşadıklarını yazarak başlamıştır. İlk romanı Baba Evi (1949), "Küçük Adamın Notları" serisinin birinci kitabıdır. Onu izleyen Avare Yıllar (1950) ise ikincisidir. Araya başka romanlar girse de Orhan Kemal hayatını yazmaya devam etmiştir. Avare Yıllar’ın devamı niteliğinde olan Cemile (1952), ilk yayımlandığında "Küçük Adamın Notları 3" üst başlığını taşır. Cemile’nin devamı niteliğinde olan Dünya Evi, çok daha sonra 1958’de yayımlanır. 1965’te yazdığı Bir Filiz Vardı romanı yaşadığı bir aşktan esinlenmesi dolayısıyla bu kapsama alınabilir. Bu otobiyografik roman serisine 1968’de yayımlanan Arkadaş Islıkları da eklenebilir.Bu romanlar, yazarın hayatından yoğun izler taşıyan ve otobiyografik özellikler gösteren eserlerdir. Bu çalışmanın amacı, Orhan Kemal’in otobiyografik ayrıntılar taşıyan altı romanını inceleyerek yazarın hayatını, romanlarına nasıl aksettirdiğini dikkatlere sunmaktır.

Biçimsel anlamda hece ölçüsüne ağırlık veren şair, Nâzım Hikmet tesiri ile serbest nazmı da dener.Orhan Kemal’in şiirlerinde görülen temel izlekler, bireysel düzlemdedir. Şahsî biyografisindeki gelişmeler, mazideki aşklar, kadın, yalnızlık, iç sıkıntısı ve sonrasında az da olsa görünüm veren toplumcu gerçekçi hususiyetler onun şiirlerindeki izleksel haritayı teşkil eder. Bununla birlikte hayata dair felsefî ol(a)mayan itirazlar ve sorgulamalar, şiirlerdeki duyuşlar arasındadır. Özellikle hapishane yıllarında yazdığı şiirlerinde karşımıza çıkan bunaltı, ontolojik derinlikten uzak bir görünüm verir. Özgürlük yitimi kaynaklı bungunluğun hâkim olduğu şiirlerin sayısı dikkat çekici seviyededir. Şiirlerde somutluk kazanan bunalmışlık hâli, eşine ve kızına duyduğu özlem, hayatın zorlukları, umulanların gerçek hayatta karşılığının olmayışı, hapishane mekânının insanı baskılayan boyutları ve mahkûmların muhtelif hâlleri genç şair Orhan Kemal’in şiirlerinin çıkış noktalarını verir.Bu çalışmada bugüne kadar üzerine pek az çalışma yapılan Orhan Kemal’in şiirlerindeki felsefî derinlikten yoksun, bireysel yaşantı kaynaklı görünüm kazanan bungunluk, bunalmışlık hâlleri ve hisleri şahıs – eser bağlamlı bir bakışla değerlendirilecektir.
Düşler ve Düş Kırıklıkları Arzular ve Fanteziler Bağlamında Orhan Kemal’in "Evlerden Biri" Romanı
Authors: KEKEÇ İsmail
Published: September 2020

Orhan Kemal’in İstanbul’a geldikten sonra kaleme aldığı romanlarından biri olan Evlerden Biri, yazarın popüler romanları kategorisinde değerlendirilmektedir. Sıradan kişilerin sıradan yaşamlarının konu edildiği eser yazarın diğer romanlarının gölgesinde kalmıştır. Ancak Orhan Kemal’in dikkati, gözlemciliği, çözümlemeleri kimi bölümlerde kendisini hissettirir. Bununla birlikte yazarların geri planda kalmış böylesi eserlerinde öne çıkan, onları diğer eserlerinden farklı kılan kimi unsurlar olabilmektedir. Evlerden Biri de barındırdığı kişilerinin arzularıyla, arzu nesneleriyle ve fantezilerinin yoğunluğuyla dikkatleri çeken bir romandır. Bu çalışmada odaklanılacak husus da romanın içerik ve teknik özelliklerinden ziyade bu unsurların, kavramların değerlendirilmesi olacaktır. Bu değerlendirme yapılırken de öncelikle arzu, arzu nesnesi, fantezi tanımlarına yer verilerek kapsamları ve çerçeveleri çizilmeye çalışılacaktır. Çizilen bu çerçeveler aracılığıyla bahsi geçen kavramlar hakkında okurun zihninde bir fikir oluşması düşünülmektedir. Ardından ilgili başlıklar altında roman kişilerinin arzularından ve fantezilerinden bazı somut örnekler verilecektir. Bu örneklerle romanda yer verilen kişilerin bu dürtülerinin ve eğilimlerinin altında yatan gerekçeler üzerine bir çözümleme yapılması planlanmaktadır.

Authors: ŞİŞMAN Gülşah
Published: September 2020

Orhan Kemal, yazın yaşamı boyunca öykü, roman, şiir, tiyatro gibi pek çok edebî türde eser vermekle birlikte Türk edebiyatındaki yerini, II. Dünya Savaşı sonrasındaki toplumsal ve ekonomik değişmeler neticesinde hayat sahnesinde ortaya çıkan ʹküçük adamʹı ve onun sosyal yapı içindeki durumunu anlattığı romanları ile elde eder. Var olanı ayıklayan, seçen, düşünsel süzgecinden geçirip hayal dünyasında yeniden üreten sanatkâr, içine doğduğu dünyayı yazarak anlamlandırmaya, metinleri aracılığıyla toplumun aksayan yönlerini görünür kılmaya çalışır. Yabancılaşma, ötekileşme, yozlaşma, sosyal adaletsizlik, yoksulluk, ölüm, sevgi gibi temler etrafında kurguladığı metinlerinin çıkış noktası insan gerçeğidir.Türk edebiyatında romancılığı ile öne çıkan Orhan Kemalʹin 89 adet şiirinin yer aldığı Yazmak Dolu Dizgin, 2002 yılında oğlu Işık Öğütçü tarafından yayıma hazırlanır. Türdeki ilk ürünlerini dönemin belli başlı şairlerinin etkisinde kaleme alan Orhan Kemalʹin şiiri, bireysel duygulanımlardan toplumcu duyarlılığa doğru evrilir. Romanlarında geliştirerek işleyeceği konu ve temaların habercisi niteliğindeki bu şiirlerinde geçim kaygısı içindeki ʹküçük adamʹın örneklerini veren sanatkâr, onun var oluş mücadelesini bireyselden toplumsala uzanan bir açılımla sunar. Bu makalede Orhan Kemalʹin sanatçı duyarlılığıyla yaklaştığı insanlık durumlarını ele aldığı şiirlerinden "Komşunun Öksüzü", "Bir Fantezi", "Benim Oğlum", "Pınar Köylü Ahmetʹin Mektubu", "Dokumacı Haydar" ve "Kantar Başından Şiirler" toplumcu gerçekçi bakış açısıyla tahlil edilecek; ʹküçük adamʹ tipinin hayaller, umutlar, gerçekler, değerler, kaybedilenler, yaşam, ölüm sarmalındaki görüngüleri ortaya konmaya çalışılacaktır.
ESCRITURA E SEU COMBATE: A FOLHA EM BRANCO
Authors: Matos Sônia Regina da Luz , Vasconcelos Roger Andrei de Castro , Cavion Camila Fátima , Pacheco Alice Virgínia de Oliveira , Rech Rudinei Fernando
Published: September 2020

Foi no Seminário de Tópicos Especiais: Escrita e seu combate – a folha em branco, oferecido no decorrer do primeiro semestre de 2019 no PPGEdu/UCS, que surgiram textos que expressam-imagem-escrita. O combate ao cruel da folha em branco foi operado nas aulas com intervenções no universo denominado acadêmico. Barthes (2000), Deleuze (1997), Guatarri (1987) estiveram presentes neste jogo de afecção do ler devorando a escrita e escrever devorando a leitura. Esse jogo junto à folha em branco passa a funcionar como condições e possibilidades da solidão/silêncio, escritura e imagem-afecção, experimentações de escritura na aula que ensaiamos com a leitura e a escrita. Com essa experimentação, movimentamos a pergunta sobre a folha em branco, que é a representação do clichê determinista do que é a escrita acadêmica. A escritura pode, talvez, desafiar as novas e as velhas certezas do que é escrita e leitura na academia? Este foi nosso desafio.

NATUREZA, ORGANISMOS E MÁQUINAS PARA O AMANHÃ ENCONTROS INESPERADOS ENTRE ARTE, CIÊNCIA E FILOSOFIA
Authors: Silva Antonio Almeida da
Published: September 2020

Engendra aqui encontros (in)esperados entre Arte, Ciência e Filosofia para pensar as máquinas e os organismos para as condições do antropoceno. Experimentemos com movimentos trazidos pelas pinturas de Fernando Vicente e as experimentações de Angelo Vermeulen que produzem e ressignificam (com) outras naturezas tecno e geneticamente inventadas, pondo outras questões à contemporaneidade. Nesse diálogo contemporâneo encontramos algumas reflexões nos estudos de Simondon, Deleuze e Guattari, Haraway, entre outros que apostam em novas interfaces da natureza. Nas diferentes produções artísticas a tecnologia e a máquina não são apenas apresentadas como uma simples ferramenta. Metais, placas de silício, elementos inorgânicos e de transição, entre outras diferentes manifestações da tecnologia, são acoplados aos seres vivos e vice e versa, a serviço de uma poética. Assim, seres orgânicos e inorgânicos evoluem conjuntamente para novas interfaces do ser. É nesse cenário que nossa pesquisa inventa outras narrativas para pensar a relação entre ciência, arte e filosofia.
O AMOR E AS RELAÇÕES AFETIVAS NA CONTEMPORANEIDADE – UMA PROPOSTA ÉTICA, ESTÉTICA E POLÍTICA
Authors: Souza Josiane Cristina Orlando de
Published: September 2020

Na contemporaneidade vivemos um modo característico de produção da subjetividade, a saber, a subjetividade capitalística. Tal subjetividade afeta a maneira como produzimos afetos e relacionamentos em nossa vida. Torna-se necessário compreender estas afetações e agenciar novos modos de experimentar o amor em sua potência. Apresentamos uma proposta baseada na ética de Espinosa, na estética da existência de Foucault e na micropolítica de Deleuze e Guattari.
SOLIDARIEDADE DESOBEDIENTE: MODOS DE EXISTÊNCIA E OUTRAS SOCIABILIDADES
Authors: Andrade Sabrina Batista
Published: September 2020

Esta proposta é um embrião de minha pesquisa de doutorado que deve ser desenvolvida entre o Norte e o Nordeste brasileiro. Visa-se investigar como se engendram ali modos de existência e sociabilidades outras, marcadas pela afetividade e solidariedade, em meio à escassez de recursos considerados tão vitais na atualidade. É também intenção da pesquisa oferecer pistas para uma nomadologia nos saberes e práticas relacionais, acadêmicas e clínicas na procura de sentidos outros para nosso presente político, tendo em vista a possibilidade de pensarmos, agirmos e vivermos de outra maneira, resistindo àquela que se impõe a nós e que hoje se materializa em formas de vida que condicionam nossos afetos e modos de existência.
PERFORMANCES COTIDIANAS COMO FUNCIONAMENTO LIGADO À VIDA: PRODUÇÃO DO NOVO, DEVIR E...
Authors: Justiniano Ana Carolina
Published: September 2020

Este artigo propõe pensar a performance no campo do educação como um funcionamento ligado à vida, como busca de fôlego em meio a tentativas de explorar e plastificar as incontáveis formas de existência, especialmente no momento atual, em que estamos sob o impacto de forças vorazmente destrutivas (ROLNIK 2018) e assistimos à escalada de forças conservadoras. Em meio a lutas por escapes e busca de ar, percebemos que surgem formas cambiantes de vida e nomadização dos viveres que potencializam os vazamentos metamórficos pelos quais os movimentos curriculares respiram e potencializam a produção do novo (PELBART 2008) bem a potência pulsante de uma educação em devir.
Catherine Deneuve e Louis Vuitton. A Publicidade de Luxo Analisada Sob o Espectro da Semiótica Peirceana
Authors: Caraciola Carolina Boari
Published: September 2020

O presente artigo analisará uma peça da campanha publicitária Journey, da marca de luxo Louis Vuitton, estrelada pela atriz francesa Catherine Deneuve, sob o prisma da semiótica de extração peirceana. A análise da publicidade, sob o espectro da teoria semiótica, permite explicitar o potencial comunicativo do anúncio a que se refere, uma vez que as estratégias semióticas utilizadas por uma marca são fatores essenciais à sua constituição como marca, sendo, portanto, de fundamental importância para a compreensão de sua natureza, perfil e efeitos emocionais e funcionais. Sendo assim, pode-se afirmar que a mensagem publicitária provoca efeitos de sentido no receptor e, com o auxílio da semiótica, é possível compreender como esse campo de sentidos ocorre.
A mocinha desviante em Glória Perez: um estudo sobre a construção de personagens em telenovelas brasileiras
Authors: Effgen Santos Matheus , De Mello Brandão Tavares Frederico
Published: September 2020

O presente trabalho busca compreender o modelo de construção de personagens empregado por Gloria Perez na criação das protagonistas femininas de suas telenovelas, tendo como recorte um estudo da personagem Ritinha, de A Força do Querer (2017). A pesquisa partiu da recuperação dos perfis de protagonistas anteriores da autora e utilizou como recurso metodológico o estudo das falas das personagens da mais recente obra de Perez, problematizando, a partir de Ritinha, complexidades da tensão entre protagonismo e autoralidade. Os resultados apontam para a configuração de uma personagem que dilui as barreiras entre o protagonismo e o antagonismo ao apresentar um perfil considerado desviante diante das mocinhas convencionais do melodrama televisivo nacional.
