Authors: SANCAKTAROĞLU BOZKURT Sinem , OKYAYUZ Ayşe
Published: June 2020

Çeviri ve toplumsal cinsiyet arasındaki ilişki son yıllarda giderek artan bir ivmeyle önem kazanmış ve alanda yapılan çalışmaların sayısı ve niteliği artış göstermiştir. Bunun sonucu olarak feminist çeviri araştırmaları diye bir alt alanın varlığından söz edilmektedir. Görsel-işitsel çeviri alt alanında toplumsal cinsiyet odaklı çalışmaların yer alması ise 2000’leri bulmuştur. Sesli betimleme, bir görsel-işitsel ürünün görsel kanalına erişimi olmayan görme engelli kişilerin erişimini sağlamak için geliştirilmiş bir görsel-işitsel çeviri türüdür. Günümüzde, bu çeviri türü, görsel-işitsel ürünlerin yaygınlaşmasıyla ve paylaşımının hızlanmasıyla önem kazanmıştır. Söz konusu çalışma feminist çeviri araştırmaları ve görsel-işitsel çeviri gibi iki çağdaş alt alanın kesişiminde yürütülmüştür. Çalışmanın amacı Türkiye’de sesli betimlemeyi en yaygın olarak uygulayan kurum olan SEBEDER’den (Sesli Betimleme Derneği) alınan veri ve dönütlerden yola çıkarak sesli betimleme alanında çalışanların, sesli betimleme metin yazarlarının veya seslendirmenlerin “cinsiyeti” üzerinden bir okuma yapabilmektir. Alıcılar açısından, sesli betimlemede “kadın seslendirmenin sesi” ve hatta “kadın sesli betimleme metin yazarının seslendirilen söylemi” gayet açık bir şekilde hissedilmektedir. Diğer çeviri türlerine kıyasla bu bağlamda “kadın çevirmen” göz ardı edilemez bir şekilde ürünün bir parçasıdır -sesi duyulmaktadır. Bu da bu alanda kadın sesine dair bulgulara gebe bir araştırma platformu sağlar. Söz konusu çalışmada bu alanda istatistiki bilgilere ve alıcı tercihlerine yer verilmekte ve bunlar feminist görsel-işitsel çeviri araştırmaları kapsamında ele alınarak yorumlanmaktadır.

Published: June 2020

Karia, Batı Anadolu’da Erken Tunç Çağı açısından çok az araştırılmış bir bölgedir. Bu nedenle, kazılarda elde edilmiş arkeolojik verilerin değerlendirilmesi, bölge açısından özel bir önem taşımaktadır. Bu çalışmada, Muğla Müzesi tarafından Yatağan ilçesindeki kömür havzasında yürütülen kurtarma kazılarında, Çapalıbağ Mevkii’nde açığa çıkarılan Erken Tunç Çağı mezarlarından elde edilen veriler ve Karia Erken Tunç Çağı içerisindeki yeri değerlendirilmeye çalışılmıştır. Tek örnek hariç tamamı pithos ve çömleklerden oluşan 19 adet mezar, bunların içinden ve çevresinden ele geçirilmiş olan seramik örnekleri ve metal buluntular değerlendirmeye alınmıştır. Mezarlığın kuzey kesiminin ETÇ IA’da, güney kesiminin ise ETÇ IB/IIA sürecinde kullanım gördüğü anlaşılmıştır. Seramik örnekleri içerisinde, Kalkolitik Çağ’dan başlayan bazı geleneklerin devam ettiği, Karia için karakteristik olan Geç-ETÇ II unsurlarının ise henüz ortaya çıkmadığı dikkat çekmektedir. Tamamı ETÇ IB/IIA evresine ait olan az sayıdaki metal buluntular, altın, gümüş ve bakır/bakır alaşımı kullanımının ve özellikle de kaplama tekniğinin bölgede erken bir süreçte kullanıldığını göstermesi açısından ilgi çekici sonuçlar vermiştir. Mezarlardan alınan mutlak yaşlandırma sonuçlarına göre, mezarlığını MÖ 3100-2600 aralığına tarihlendirilmesi mümkün olmuştur.

Authors: Mikhnov G. I. , Miroshnichenko D. B.
Published: June 2020

One of the serious complications after limb injuries is the development of Sudeck–Turner syndrome (refl ex sympathetic dystrophy). The pathology development frequency has recently increased, and varies, according to various literary sources, from 5 to 40 %. The pathology has a progressing nature, and is accompanied by chronic pain, impaired limb function, trophic disorders, gradual deformation of the limb, the development of osteoporosis, stiffness of adjacent joints, and often ends with the patient disability. Patients of this category have a long time treatment (up to 4–6 or more months after removal of immobilization). Various methods of conservative treatment are used: drug therapy, physiotherapy, exercise therapy, blockade, and finally with prolonged and unsuccessful conservative therapy, various types of surgical techniques. But even for the entire complex of modern treatment methods applying the outcome could be unfavorable - contracture develops. So the severity and duration of the disease, the treatment low efficiency, the unpredictability of the pathological process outcome forces traumatologists to look for new treatment methods.
Neurophysiological aspects of enuresis in children
Authors: Safiullina G. I. , Yakupov R. A. , Safiullina A. A.
Published: June 2020

Introduction. Enuresis is a pathological condition, manifested by involuntary urination during sleep or in the wakeful state. It is believed that enuresis is associated with unformed or impaired self-control skills for emptying the bladder. The significance of the problem is determined by the widespread prevalence of pathology, social and psychological maladaptation of children with enuresis. An important role in this plays the development of their personality by an accentuated type often, difficult adaptability, and lack of ability to integrate into the team, especially into the semi or closed type. According to modern concepts, enuresis can be caused by the following reasons: delayed maturation of the nervous system, urological pathology and urinary tract infection, impaired activation reaction during sleep, impaired rhythm of secretion of antidiuretic hormone, adverse heredity, psychological factors and stress. The results of Russian and foreign scientists studies revealed the polyetiological character of enuresis and the impossibility, in most cases, of identifying its obvious cause. This explains the relatively wide variability of outcomes: from spontaneous cure to apparent resistance to all existing treatments. The significant prevalence of enuresis, the relative severity of this pathology and the lack of effective treatment methods necessitate the search for alternative methods of therapy or fundamentally new approaches to using existing ones, which is impossible without a thorough study of this disease etiopathogenesis.

The goal of research — is to study the neurophysiological characteristics of enuresis in children.

Materials and methods. Prospective controlled study was conducted in Kazan State Medical Academy — a branch of the RMACPE (Kazan) in the period 2003–2019 years. To study enuresis mechanisms we carried out a comprehensive clinical-electroneurophysiological examination of 93 children aged 5 to 15 years, suffering from bedwetting. The control group consisted of 40 healthy children who were comparable in age and gender to those in the main group. All patients underwent a comprehensive examination, which included the study of complaints, anamnesis, clinical and electroneurophysiological research.

Results. Clinical examination of children with enuresis revealed signs of minimal cerebral dysfunction. An electrophysiological examination made it possible to determine an increase in the refl ex excitability of brain stem structures against the background of a decrease in downward inhibitory control.

Conclusion. The predominance of excitation processes over inhibition in the central nervous system is mainly observed in children with enuresis. The weakness of the inhibitory mechanisms due to constitutional factors, pathology of the nervous system that took place earlier, allows making an assumption about the diffuse nature of the disorders of the nervous system in this urination disorder.
The use of osteopathic correction in conjunction with radon baths at the sanatorium-resort stage of rehabilitation of patients with dorsopathy
Authors: Ul′ikhina N. V. , Shiryayeva E. E.
Published: June 2020

Introduction. Dorsopathy occurs in 90 % of people throughout life, and is in the first place for the duration of temporary disability in people after 45 years. The sanatorium-resort phase of rehabilitation, including usually physiobalneotherapy, is important in the treatment of dorsopathy. Radon therapy is one of the physiobalneotherapy types. However the effectiveness of radon monotherapy is not more than 25–38 % for various forms of dorsopathy. Therefore a combination of balneotherapy with additional methods of infl uencing on the organism is used in modern balneology to increase the effectiveness of therapy and to ensure the achievement of a positive treatment result in a shorter time without pathological balneoreaction and exacerbation. Osteopathic correction can be considered as such an additional method of infl uencing on the organism, because it triggers a cascade of regulatory reactions at the local, regional and global levels, and these reactions have a cumulative and prolonged effect.

The goal of research — to substantiate the possibility of osteopathic correction using in conjunction with radon baths at the sanatorium-resort stage of rehabilitation in patients suffering from dorsopathy.

Materials and methods. The study involved women aged 25 to 60 years, with a diagnosis of dorsopathy, taking radon therapy. Using the method of simple randomization with a random number generator, the main group (30 people who received radon therapy and osteopathic correction, OC), and the control group (30 people who received only radon therapy) were allocated. At the beginning and the end of treatment the osteopathic status examination of each patient was conducted in parallel with the study of their reactive anxiety level, assessed according to the Spielberger–Hanin scale, the body′s resistance to hypoxia, assessed in the Stange test by the length of breath-holding after inspiration, and the adaptive capacity of the circulatory system, assessed by Coefficient of adaptation L. Kh. Garkavi. The results were processed using nonparametric statistics.

Results. It was found that if OC was included in radon balneotherapy, the state of patients suffering from dorsopathy improves statistically significantly (p<0,0001) by the following indicators: the total number of somatic dysfunctions in patients and the number of regional dysfunctions decreased, the level of reactive anxiety decreased, the body′s resistance to hypoxia increased, the adaptive potential of the circulatory system increased. The changes of all indicators in the main group receiving OC in addition to radon therapy were significantly more pronounced than in the control group receiving only radon therapy (p≤0,0001).

Conclusion. The results obtained during this study allow recommending the use of osteopathic correction to enhance the effect of the sanatorium-resort treatment.

An Optimization Method for Semilinear Parabolic Relaxed Constrained Optimal Control Problems
Authors: KOKKİNİS Basil
Published: June 2020

This paper addresses optimal control problems governed by semilinear parabolic partial differential equations, subject to control constraints and state constraints of integral type. Since such problems may not have classical solutions, a relaxed optimal control problem is considered. The relaxed control problem is discretized by using a finite element method and the behavior in the limit of discrete optimality, admissibility and extremality properties is studied. A conditional descent method with penalties applied to the discrete problems is proposed. It is shown that the accumulation points of sequences produced by this method are admissible and extremal for the discrete problem. Finally, numerical examples are given.
Maximal and Willmore Null Hypersurfaces in Generalized Robertson-Walker Spacetimes
Authors: ATİNDOGBÉ Cyriaque , HOUNNON Hippolyte
Published: June 2020

We establish after some technical results a characterization of maximal null hypersurfaces in terms of a constant mean curvature screen foliation (in the slices) induced by the Chen's vector field. Thereafter, bounds are provided for both the squared norm of the (screen) shape operator for non totally geodesic maximal null hypersurfaces and the scalar curvature of the fiber. In terms of the scalar curvature of the fiber and the warping function, we establish necessary and sufficient conditions for Null Convergence Condition (NCC) to be satisfied in which case we prove that there are no non totally geodesic maximal null hypersurfaces. A generic example consisting of graphs of functions defined on the fiber is given to support our results. Finally, we provide lower bounds for the extrinsic scalar curvature and give a characterization result for Willmore null hypersurfaces in generalized Robertson-Walker spacetimes.

Causality, Confounding, and Simpson’s Paradox
Authors: ZAMAN Asad , SALAHUDDİN Taseer
Published: June 2020

Bitter fighting among Christian factions and immoral behavior among Church leaders led to a transition to secular thought in Europe (see Zaman (2018) for details). One of the consequences of rejection of religion was the rejection of all unobservables. Empiricists like David Hume rejected all knowledge which was not based on observations and logic. He famously stated that: ““If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: for it can contain nothing but sophistry and illusion.” David Hume further realized that causality was not observable. This means that it is observable that event Y happened after event X, but it is not observable that Y happened due to X. The underlying mechanisms which connect X to Y are not observable. Current Article discusses the impact of changing causal structures on relationships and results of econometric analysis. it shows that conventional econometric analysis is devoid of causal chains which makes it impossible to get realistic results.

Published: June 2020

Patients might have teeth that are extremely mobile and/or misaligned. If multiple teeth are retained with different long axes, retrieving the impression could dislodge some of the teeth for which the long axes are inconsistent with the path of removal.
In this case series, three different impression materials are used, which are low viscosity PVS (Polyvinylsiloxane), PE (Polyether) and irreversible hydrocolloid. The impression has been made to record Grade III mobile teeth. These materials quickly polymerize and do not adhere to each other intraorally. The impression is separated in three different directions to prevent any movement of the mobile teeth and reassembled extra orally before pouring.
This article describes various simple and safe methods to make impressions of extremely mobile teeth.

Keywords:

Periodontally compromised teeth, Mobile teeth, Impression techniques, PVS (polyvinylsiloxane), PE (polyether), irreversible hydrocolloid, immediate dentures.

Introduction: Although several coronavirus disease 19 (COVID-19) studies have focused on the biomedical and epidemiological manifestations of the COVID-19 virus, there is a dearth of studies that have reported the experiences of COVID-19 survivors. This study investigated the physiological and psychological experiences of COVID-19 survivors and the quality of care that they received during their recovery processes. Methods: A phenomenological approach and a purposive sampling technique were employed to select eligible participants whose reported interviews/videos were published on reputable online media channels. The selection processes involved three researchers who had independently searched and assessed the interviews and their sources; for veracity, availability of vital information to meet the study objectives, and to ensure it followed the inclusion criteria. Video interviews were transcribed and data were analyzed using thematic analysis. Results: Thirty-nine participants (COVID-19 survivors) within the age range of 20-95 from over 15 countries and 5 continents were included in this study. Clinical symptoms commonly reported included feeling feverish, severe, persistent and dry cough, difficulty in breathing, cold, body pains, and aches. Many participants had negative mental health experiences such as being scared, anxious, guilty feelings, and worrying about their recovery. Few participants had positive mental health experiences such as the feeling of encouragement from family and trusted friends. Many participants were satisfied with the quality of care at health centers, though some experienced early difficulty in getting tested. Conclusion: There are psychological impacts associated with the SARS-CoV-2 infection. Psychological interventions should be included in the management of COVID-19 patients and survivors.

Pengukuran merupakan suatu hal yang tidak dapat dipisahkan dalam kehidupan sehari-hari. Kurangnya alat ukur dengan resolusi tinggi, masih meninggalkan suatu rintangan dalam hal pengukuran medan magnetik lemah.  Salah satu metode yang dapat dilakukan untuk mengukur medan magnet adalah metode fluxgate. Rentang kerja sensor fuxgate untuk mendeteksi medan magnet berkisar antara 10−10 − 10−4T baik DC maupun AC. Sensor fluxgate memiliki sensitivitasyang tinggi, stabil terhadap suhu tinggi, daya operasi yang rendah, ukuran yang kecil, serta resolusinya hingga 10 pT. Sehingga sensor fluxgate sangat cocok untuk mengukur medan magnetik yang lemah. Telah dilakukan karakterisasi terhadap sensor magnetik flusxgate dengan konfigurasi 2 × (1000/500/1000).  Sensitivitas yang diperoleh sebesar 17,793 V/µT dan resolusi sensor sebesar 56,2 pT/mV.

Development of energy especially alternative energy and renewables continue to be encouraged, one of which is becoming the trend of the world today is focused towards the development of solar energy. The optimum angle of tilt of the photovoltaic panel is one of the deciding factor against the acceptance of the amount of solar radiation in the amountof the maximum, so that will affect the power output of a photovoltaic panel. Method of calculation of the Altitude angle is a way to find out the optimum height of the positions of the Sun, and these factors influence the position of the slope of the surface of the panel sector in the region, so by knowing the position of the right angle of the Sun will be able to obtain the maximum amount of radiation against photovoltaic panels. Adjustment of the angle of the slope against the monthly solar panels in the region of Meulaboh is affected by the angle of altitude. January and March, the optimum angle value starts from 35,54 ° to  12,39°. April does not occur, because of the angle position  of the panel surface horizontal is same. May to December, the orientation of the panel turned south-facing surface of the panel with face down which is characterized by a negative notation.

Pengaruh dari Direct Field Component pada Ruang Akustik dengan menggunakan SEA Model
Authors: Munawir Al , Darsan Herri , Murhaban Murhaban
Published: June 2020

Statistical Energy Analysis (SEA) is a well-known method to analyze the flow of acoustic and vibration energy in a complex structure. This study investigates the application of the corrected SEA model in a non-reverberant acoustic space where the direct  field component from the sound source dominates  the total  sound  field rather than  a diffuse field in a reverberant space which the  classical SEA model assumption is based on. A corrected SEA model is proposed where the direct ﬁeld component in the energy is removed and the power injected in the subsystem considers only the remaining power after the loss at ﬁrst reﬂection.  Measurement is conducted a box divided into two rooms separated by a partition with an opening where the condition of reverberant and non-reverberant can conveniently be controlled. In the case of a non-reverberant space where acoustic material was installed inside the wall of the experimental box, the signals are corrected by eliminating the direct ﬁeld component in the measured impulse response. Using the corrected SEA model, comparison of the coupling loss factor (CLF) with the theory shows good agreement.

Published: June 2020

Baja tahan karat AISI 304 secara umum digunakan pada mesin-mesin konstruksi terapan sederhana seperti poros propeler kapal nelayan, mesin penghancur es, pemeras tebu danlainnya, dikarenakan ketahanan korosifnya yang baik, disisi lain kelemahan AISI 304 pada kondisi lapangan sering mengalami deformasi dan kepatahan dengan putaran yangrelatif  tinggi. Untuk mengatasi hal tersebut dapat dilakukan  usaha  menambah  nilai kekerasan permukaan dengan melakukan pengujian Jominy Hardenability. Pengujian Jominy yang dilakukan pada spesimen uji dengan standar ASTM A255-02, dengan laju air pada nozzle 45 liter/menit, pada temperature 8500C dan holding time 15-20 menit. Hasil pengujian menunjukkan bahwa nilai awal kekerasan permukaan pada ujung quenching  sisi A adalah 187  HB dan pada  sisi B adalah  170 HB. Nilai kekerasan permukaan setelah di normalizing pada ujung quenching sisi A adalah 182 HB dan pada sisi B adalah 188 HB. Maka terjadi penurunan kekerasan pada sisi A sebesar 5 HB, dan terjadi peningkatan kekerasan pada sisi B sebesar 18 HB. Setelah di uji Jominy nilai kekerasan pada sisi A adalah 227 HB, dan pada sisi B adalah 223 HB. Pada pengujian jominy terjadi peningkatan kekerasan pada ujung sisi A sebesar 45 HB, dan peningkatan kekerasan  pada  sisi B sebesar 35  HB. Hasil penelitian  ini dapat direkomendasikan bahwa AISI 304 sebelum digunakan sebaiknya dilakukan pengerasan permukaan sehingga sifat mekanik bahan menjadi lebih optimal.
