    Does Robot-assisted Surgery in Urology Has Benefits? The Current Status
    (2019) Sah, Cem; Kuzgunbay, Baris; 0000-0001-5598-4666
    Minimally invasive surgery has gradually replaced the conventional surgery with the introduction of laparoscopy. Subsequently, with intensive advertisement and marketing strategies, robot-assisted surgery became popular and robot-assisted surgery has been used in almost every surgical procedure. Despite its high cost, the robotic platform, which has proven its general advantages such as less hospital stay and less blood loss, has become controversial in the literature in terms of cost effectiveness. In this study, the advantages and disadvantages of the robot-assisted surgery in urology have been reviewed in the light of current literature.

    Assessment of Hemoglobin Stability in Chronic Hemodialysis Patients Receiving Erythropoietin Therapy and the Effect of Hemoglobin Stability on Risk of Cardiovascular Disease
    (2019) Guncan, Melda Ulas; Guncan, Sabri; Torun, Dilek
    Objective: Anemia is one of the most important factors that decrease the quality of life in patients with end-stage renal desease receiving hemodialysis treatment. In these patients, Erythropoietin stimulating agents (ESAs) are used in the treatment of anemia. Although the target hemoglobin (Hb) value in chronic renal failure is 11-12 gr/dL, it is suggested that hemoglobin values fluctuate between normal, high and low values in the great majority, leading to cardiovascular structural changes which increase mortality. In this study, we investigated the effect of anemia and hemoglobin fluctuations on mortality rate and the risk of cardiovascular disease in chronic hemodialysis patients who received ESA thearapy. Materials and Methods: Hemoglobin values for 12 months of 181 patients were examined. The target Hb level was 11-12 gr/dL interval and the patients were divided into 6 groups according to the hemoglobin values; persistently low, low-normal, target, normal-high, low-high and persistently high. According to the variability in hemoglobin level, groups were compared in terms of demographic, laboratory characteristics, treatment, risk of cardiovascular disease, hospitalization and death frequency and causes. Result: The total of 181 patients were classified according to Hb levels; 22 (12.2%) patients were persistently-low, 72 (39.8%) were low-normal, 10 (5.5%) were normal-high and 77 (42.5%) patients were low-high Hb group. During the 12 month fallow up, there were no patients in target and high Hb group. The groups were similar in terms of the presence of comorbid diseases such as diabetes, hypertension, coronary artery disease and other demographic characteristics, and there was no difference between groups in terms of cardiovascular disease development. ESA doses and blood transfusion counts and mortality rates were significantly higher in the persistently-low hemoglobin group compared to the other groups. Conclusion: In our study, high rate of anemia and hemoglobin fluctuations were shown in chronic hemodialysis patients and anemia was associated with mortality. However, the possible association of these variables with cardiovascular diseases was not observed. Further studies are needed in the larger hemodialysis patient group to investigate the relationship between hemoglobin fluctuation and mortality and cardiovascular risk.

    Square root central difference-based FastSLAM approach improved by differential evolution
    (2016) Ankishan, Haydar; Ari, Fikret; Tartan, Emre Oner; Pakfiliz, Ahmet Gungor
    This study presents a new approach to improve the performance of FastSLAM. The aim of the study is to obtain a more robust algorithm for FastSLAM applications by using a Kalman filter that uses Stirling's polynomial interpolation formula. In this paper, some new improvements have been proposed; the first approach is the square root central difference Kalman filter-based FastSLAM, called SRCD-FastSLAM. In this method, autonomous vehicle (or robot) position, landmarks' position estimations, and importance weight calculations of the particle filter are provided by the SRCD-Kalman filter. The second approach is an improved version of the SRCD-FastSLAM in which particles are improved by a differential evolution (DE) algorithm for reducing the risk of the particle depletion problem. Simulation results are given as a comparison of FastSLAM II, unscented (U)-FastSLAM, SRCD-Kalman filter-aided FastSLAM, SRCD particle filter-based FastSLAM, SRCD-FastSLAM, and DE-SRCD-FastSLAM. The results show that SRCD-based FastSLAM approaches accurately compute mean and precise uncertainty of the robot position in comparison with FastSLAM II and U-FastSLAM methods. However, the best results are obtained by DE-SRCD-FastSLAM, which provides significantly more accurate and robust estimation with the help of DE with fewer particles. Moreover, consistency of the DE-SRCD-FastSLAM is more prolonged than that of FastSLAM II, U-FastSLAM, and SRCD-FastSLAM.

    The Wide Open Windows of Cholera Street: On the Light and Sound Leaking Through/To the Private Space
    (2018) Aytemiz, Pelin; AAE-9744-2022
    Inspired by the subaltern studies the purpose of this article is to examine how the dichotomy of private/public in Metin Kacan's Agir Roman Novel is reproduced on the axis of the visual language used by Mustafa Altioklar's cinematic adaptation Cholera Street. The article is interested in the peculiar choice of slang usage and reads this as an invitation to blur the borders of private/public space that modern life demands to keep separate. In this sense, Cholera Street can also be regarded as a brilliant piece of social commentary, offering a vivid peek into the life of the "other" trapped in the peripheral neighborhood. This article unravels further how Cholera Street through visual film grammar and various metaphors sends strong critical messages about the silence of subalterns who often lack the means to speak for themselves and how the violation of privacy turns out to be a challenging act against the dominant order.

    Sınır Sorununun Etik Açıdan Saydamlığı: Haberin Reklamdan Ayırt Edilmesi
    (International Symposium on Media and Politics., 2007) Aygün Cengiz, Serpil
    Türkiye’de reklam metinlerinin etik açıdan sorunlu olduklarında değerlendirildiği üç kurum bulunmaktadır: Radyo ve Televizyon Üst Kurulu (RTÜK), Sanayi ve Ticaret Bakanlığı Reklam Kurulu ve Reklam Özdenetim Kurulu. Bu üç kuruluşun da tabi olduğu kanun ve yönetmeliklerde “reklamların ayırt edilmesi” bağlamında reklam metinlerinin yayınlandıkları mecrada reklam metni olduğunun açıkça anlaşılması gerektiğine dair hükümler açıkça yer almaktadır (RTÜK Radyo ve Televizyon Yayınlarının Esas ve Usulleri Hakkında Yönetmelik Madde 20; Sanayi ve Ticaret Bakanlığı Reklam Kurulu Tüketicinin Korunması Hakkında Kanun Madde 16; Reklam Özdenetim Kurulu Uluslararası Reklam Uygulama ve Esaslan Madde 20). Kitle iletişim araçlarında yer alan reklamlarda söz konusu yerleşik kural zaman zaman değişik şekillerde çiğnenmektedir. Yazılı basında (örtülü reklamlardan farklı olarak), içinde yer aldıkları mecrada reklam metni olduğunun açıkça anlaşılamadığı reklam metinlerinin yapısına bakıldığında bunların beş temel kategori altında incelenebileceği görülmektedir: Haber metni formatındaki tasarımı nedeniyle haber metninden ayırt edilemeyen reklam metinleri; sayfada yanında bulunduğu haber metninin içine tasarımı gereği sızan ve diğer metin(Ier)den ayırt edilemeyen reklam metinleri; sayfadaki haberi çerçeveleyen ve sayfa içinde haber metnindeki dilsel/görsel unsurlarla çerçevede reklamı yapılan ürüne çapa atılan reklam metinleri ve gazetenin eki olarak verilen ama gazete formatmda hazırlanmış olduğu için ilk bakışta reklam eki olduğu anlaşılamayan reklam metinleri. Yazılı basında haber formatı biçiminde veya bu haber metinlerinin içine değişik grafik tasarımlarla sızan ve yayınlandığı mecrada yer alma şekli ile haber metninden kolaylıkla ayırt edilemeyecek biçimde sunulan bu reklam metinleri etik açıdan önemli bir sorun barındırmaktadır. Bu çalışmada, reklamların ayırt edilmesiyle ilgili etik ilkeye bu beş kategori altında nasıl uyulmadığı, Örnekler üzerinden gösterilerek ilgili etik kuralın tartışmaya açılması hedeflenmektedir. According to the both international and national code of media ethics journalists should “distinguish news from advertising and shun hybrids that blurs the lines between the two”. The so called ethical rule in mass media sometimes is broken. When analysing the structure of advertisements in press as vary different from implicit ones, it can be observed that those advertisements which breaks the rule may be structured in five categories. The advertisement texts which cannot be differentiated from news because of the design of news format in page, the advertisement texts which are penetrated to the news next to turn and therefore cannot be differentiated from other news, the advertisement text which are framed as comprising the news or the advertisements which are anchored the advertising products by the news through verbal/visual elements; and the advertisement texts which cannot be grasped as advertising texts at place because of being supplement of the newspaper which have the same design with it. There is an important ethical problem in such advertisements which are either formatted as the news or penetrated in the news through various graphical designs. This study aims to discuss the ethical rule about distinguishing news from advertising by showing how this ethical rule is broken in press.

    Empatik Yaklaşımla Sanal Terapide Duygusal Okuryazarlık
    (International Symposium Emotional Intelligence and Communication Kongre Kitabı., 2007) Aygün Cengiz, Serpil
    Sigmund Freud için başka bir insanı anlamada en önemli payı oluşturan bir süreç olarak ‘empati’, Sândor Ferenczi ve Heinz Kohut’un çalışmalarıyla psikoterapi alanında önemli bir yer kazanmıştır. Cari Rogers’m katkılarıyla günümüze dek uzanan anlayışa göre ‘empati’, kişinin karşısındakinin yerine kendisini koyması ve diğerinin duygu/düşüncelerini doğru olarak anlayıp duyumsayarak bunu iletebilmesidir. Duygusal zeka çalışmaları alanındaki öncü çalışmalarıyla bilinen Daniel Goleman’m tanımlaması ile empati, “başkasının ne hissettiğini sezebilmenin anahtarı ses tonu, mimikler, jestler, yüz ifadesi ve benzeri türden sözsüz ifadeleri okuyabilmektir”. Bü yönüyle de empati kurma becerisi psikoterapi alanında çok önemli bir yetenek/donanım olan “duygusal okuryazarlığın” olmazsa olmazlarından biridir. Ancak sanal ortamda yüz yüze (f2f) yapılan geleneksel terapilerde olduğu gibi danışmanın yararlanabileceği danışanın ses tonu ve beden diline ilişkin görsel ipuçlan olmadığı için danışman geleneksel terapistten çok daha gelişkin bir duygusal zekaya sahip olmak zorundadır. ‘Empathy’ as understanding the other’s situation or feelings for Sigmund Freud became very important in the field of psychotherapy for also Sândor Ferenczi ve Heinz Kohut. The concept of empathy, which comes to todays through contributions of Carl Rogers, means to put himself/herself in place of other and to transmit the other’s feelings and thoughts truly by comprehending and perceiving him/her. With these aspects, the ability to make empathy is an essential component of emotional literacy which is an inportant skill capacity of emotional intelligence becomes much more important in online therapy since the absence of the visual clues such as the voice tone and body language of the patient forces the online therapist to have more emotional intelligence than the traditional therapist.
