Right Coronary Artery Aneurysm Masquerading as a Pericardial Cyst: A Case Report
Authors: Bharath Konda , Parvathareddy Krishna Malakonda Reddy , Nagula Praveen , Avinash Birajdar
Published: April 2024

Coronary artery aneurysms (CAAs) or ectasias are dilatations of arterial segments, commonly detected as an incidental finding during angiography. The incidence of CAAs varies from 0.3% to 5.3%, mainly caused by atherosclerosis, though infections, inflammatory conditions, and connective tissue disorders can also contribute. Giant CAAs are rare with a reported prevalence of 0.02–0.2%. In our case, a 45-year-old female has been diagnosed with a giant aneurysm in the right coronary artery, which was initially misinterpreted as a pericardial cyst. In addition, she has a bicuspid aortic valve and severe aortic stenosis, hence advised for surgical management.
Do Hepatic Fibrosis and Steatosis Measured by Hepatic Transient Elastography (FibroScan) Predict Cardiovascular Risk in Patients with Non-alcoholic Fatty Liver Disease: An Observational Cross-sectional Study
Authors: Goyal Prerna , Chopra Rahul , Goyal Omesh
Published: April 2024

Objectives:

Non-alcoholic fatty liver disease (NAFLD) has been associated with increased cardiovascular risk (CVR) in the previous studies. In the majority, ultrasonography has been used to diagnose and stage NAFLD, which lacks sensitivity and is non-quantitative. Other more sensitive, comprehensive, and quantitative diagnostic tools such as vibration-controlled transient elastography (TE) have largely been underused in research work. TE-driven liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) provide an accurate and simplified estimation of liver fibrosis and steatosis, respectively. Therefore, we aimed to analyze the association between these two objective, robust parameters and CVR.

Materials and Methods:

In this observational cross-sectional study, NAFLD participants were divided into two distinct categories of steatosis (CAP <290 and ≥290 dB) and fibrosis (LSM <10 and ≥10 kPa). Their CVR assessment was done by calculating Framingham risk score (FRS), American College of Cardiology/American Heart Association Pooled Cohort Equation Score (ACC/AHA PCES), and carotid intimal medial thickness (CIMT).

Results:

A greater number of participants presented with mild-moderate fibrosis (n = 41, 62.1%) as compared to severe fibrosis (n = 25, 37.8%) whereas severe steatosis participants predominated (n = 52, 78%) as compared to mild-moderate steatosis. The presence of significant fibrosis (LSM ≥10 kPa) was independently and significantly associated with FRS, ACC/AHA PCES, and CIMT. On the other hand, the presence of significant steatosis (CAP ≥290 dB/m) was not significantly associated with any CVR marker (FRS, ACC/AHA PCES, or CIMT), though a greater number of participants with CIMT >0.7 belonged to severe steatosis group.

Conclusion:

Subjects with severe fibrosis (LSM ≥10) had a significantly higher CVR, whereas severe steatosis (CAP ≥290) alone failed to predict CVR. Therefore, CVR reduction strategies can be targeted primarily in NAFLD subjects with fibrosis, particularly in resource-limited healthcare settings.

Authors: Gültekin Fatma , Hatipoğlu Temizel Esra , Erdoğan Nergis
Published: April 2024

Ülkemizin maden suyu bakımından önemli kaynaklara sahip olduğu, fakat tüketim oranlarının oldukça düşük olduğu MASUDER (Madensuyu Üreticileri Derneği) tarafından belirtilmiştir. Bu durum maden suyunun etkilerinin yeterince bilinmemesiyle ilişkilendirilebilir. Günümüze kadar yapılan çalışmalar maden sularının kalp ve damar sağlığı, kemik yapısı, sindirim sistemi ve metabolizma üzerine olumlu etkileri olduğunu göstermiştir. Sağlık üzerine etkileri hakkındaki bilincin artması tüketimi olumlu yönde etkileyecektir. Tüketimin artması ile mineralli su kaynaklarının ekonomik değeri de artmış olacaktır. Bu çalışmada Artvin ilinin Şavşat ilçesinde yer alan Ciritdüzü mineralli su (CDMS) ve bazı soğuk su kaynaklarının hidrojeokimyasal ve izotopik özelikleri incelenmiş, sağlık açısından değerlendirilmesi yapılmıştır. Na-Ca-HCO3, Ca-Mg-Na-HCO3 ve Ca-HCO3 su tiplerinde olan kaynakların sıcaklıkları yaklaşık 8 - 13 °C, pH değerleri 6,42-7,97 ve EC değerleri 181-3.195 µS/cm arasında değişmektedir. Suların izotop içerikleri (O-18, döteryum ve trityum) CDMS’nin derin, diğer kaynakların sığ dolaşımlı olduğunu göstermiştir. Sularda ölçülen δ34S değerleri CDMS’de sülfatın kaynağının denizel evaporitler, karasal evaporitler ve atmosferik sülfatın karışımı olduğunu; δ13C değerleri karbonun kökenin metamorfik CO2’ye karşılık geldiğini işaret etmektedir. Sulardaki iz element içerikleri genel olarak Doğal Mineralli Sular Hakkındaki Yönetmelikte verilen sınır değerlere uygunken CDMS’de antimon ve arsenik konsantrasyonları sınır değerlerde, bor konsantrasyonu ise sınır değerin üzerindedir. Sular Tıbbi ve Klimatolojik bakımdan değerlendirildiğinde CDMS içme kürlerinde etkili dozların üzerinde bikarbonat içeriğine sahiptir. Sodyum, kalsiyum ve magnezyum iyon içeriği bakımından değerlendirildiğinde CDMS sindirim sistemi ile ilgili hastalıklarda, kalp damar hastalıklarının önlenmesinde, böbrek ve idrar yolu hastalıklarında kullanılabilecek bir kaynaktır. Bu hastalık gruplarında koruyucu ve tedavi edici özellikte olan CDMS kaynağının yer aldığı bölge klimaterapi olanağı sunmaktadır.
Péritonite à Kocuria Rhizophila en dialyse péritonéale : A propos de 2 cas et revue de la littérature
Authors: Lefur Awena , Querard Anne-Hélène , Couvrat-Desvergnes Grégoire
Published: April 2024

Les auteurs rapportent deux cas cliniques de péritonite à Kocuria rhizophila, un germe peu fréquent mais pathogène, survenus dans un centre de dialyse sur une période de trois mois en 2022. Ces cas ont nécessité la dépose du cathéter de dialyse péritonéale, illustrant la gravité potentielle de ces infections. Les auteurs décrivent les caractéristiques clinico-biologiques de ces péritonites et soulignent la difficulté de distinguer Kocuria des autres cocci Gram positif, comme les staphylocoques, en raison de leur ressemblance morphologique, et la nécessité d’une identification précise pour un traitement approprié.

La discussion aborde la fréquence et la gestion des péritonites à Kocuria en France, basée sur une étude observationnelle de cohorte utilisant les données du Registre de Dialyse Péritonéale de Langue Française (RDPLF) entre janvier 2018 et mai 2023. Cette étude a révélé que les péritonites à Kocuria représentaient 3,5% des péritonites documentées, Kocuria rhizophila étant le plus fréquemment identifié. L’étude met en évidence un taux important de récidives et la nécessité fréquente de retirer le cathéter, soulignant la gravité de ces infections.

Conclusion : Les auteurs suggèrent qu’en cas de péritonite à Kocuria rhizophila, une dépose-repose rapide du cathéter pourrait être envisagée en raison du taux élevé de récidives. Ils appellent également à une vigilance accrue et à un suivi rapproché des patients traités conservativement par antibiothérapie pour minimiser le risque de récidive et d’échecs techniques, indiquant un besoin de stratégies thérapeutiques adaptées face à ce pathogène spécifique.

Authors: Hmaidouch Nabil , El Maakoul Sara , Fitah Hajar , Ouzeddoun Naima , Benamar Loubna
Published: April 2024

Introduction: The understanding of the pathophysiological mechanisms of repeat peritonitis, defined as the occurrence of peritonitis more than 4 weeks after the end of appropriate antibiotic treatment for a previous episode involving the same germ, remains limited.
Methods: We studied the outcomes of 26 episodes of repeat peritonitis between 2006 and 2024 (Repeat Group) and compared them with 23 episodes of relapsing peritonitis (Relapse Group) and 84 episodes of peritonitis preceded by 4 weeks or more by another episode with a different organism (Control Group).
Results: The majority of cases of repeat peritonitis are caused by gram-positive organisms (65.5%), predominantly Staphylococcus aureus (38.5%), whereas most episodes of relapsing peritonitis are culture-negative (69.5%), followed by gram-negative bacilli episodes (17.4%). Exit site infection is significantly associated with PD peritonitis. Gram-positive cocci are responsible for 95.5% of exit site infections, mainly due to Staphylococcus aureus. In the Repeat Group, 14 (66%) patients achieved primary response, and 10 (47%) of them reached complete cure. After the first episode of repeat peritonitis, 3 (14%) patients had their catheter removed and were transferred to long-term hemodialysis. ; however, the risk of developing relapsing peritonitis was 4.7%, and recurrent peritonitis was 9.5%.
Conclusion: The definition of repeat peritonitis is clear. Despite a favorable outcome with antibiotic treatment, the risk of further episodes of peritonitis remains high, threatening the time on peritoneal dialysis therapy and the life of the patient.

Published: April 2024

Stunting is a condition of growth failure due to accumulated nutritional inadequacies from prenatal until two years old. Individuals' perceptions of perceived benefits influence exclusive breastfeeding and thus reduce the risk of stunting. This study aimed to analyze the perception of the benefits of breastfeeding in preventing stunting in Tuah Negeri District, Musi Rawas Regency. The research method used a quantitative approach with a cross-sectional design. Sampling using purposive sampling technique resulted in 154 respondents aged 6-36 months. Data analysis used frequency distribution, chi-square test, and logistic regression test. Univariate results, good attitude (perceived benefits) 58.4%, high knowledge 66.2%, not good practices 57.1%, age <30 years 50.6%, low education 55.2%, not working 86.4%, family income below minimum wage 93.5% and number of family members ≤4 57.1%. Mothers’ knowledge has a relationship with exclusive breastfeeding practices (p<0.05) However, there was no relationship between perceived benefits of breastmilk reflected through attitudes and exclusive breastfeeding practices, as well as age, education, occupation, income and number of family members. Multivariate showed that low mothers’ knowledge had a 3.1 times higher risk of have unfavorable practices in exclusive breastfeeding, controlled by mother’s education. Based on study, the government needs to conduct education and long-term approaches through formal education so that mothers better understand health information.

Authors: Fatimah Nur , Soviyah Soviyah
Published: April 2024

Courses in TEYL (Teaching English to Young Learners) at the tertiary education level have been conducted in different universities including at the English Department of Universitas Ahmad Dahlan. One of the courses is TEYL Program Development (TEYL PD). It is to develop materials and/or program in TEYL. Since there’s not yet specific and detailed information regarding its assessment in the class of TEYL PD implementing project-based learning, this research aims to design instruments to measure the learning achievement in TEYL PD course. This research utilizes Research and Development (R&D) with ADDIE model. The development process encompasses five steps i.e. analyze, design, develop, implement, and evaluate. There are two rubrics resulted for the course to assess the students in doing the project on TEYL PD. The first is the rubric to assess group’s performance and the second is the one to measure individual performance related to the group project. The instrument for the group performance contains 7 aspects (stages of the project, data collection, target accomplishment, reporting, knowledge, attitudes, and skills). Individual performance was based on peer ranking on the aspects on the students’ contribution, collaboration, discipline and communication.  At this preliminary study, implementing the instruments was conducted by the test of readability and content validity by an expert in English language teaching. Further, the evaluation was realized based on their feedback. Further research is in demand to investigate the use of the instruments in the classroom setting on TEYL PD course.

Authors: Pietrzyk Sławomir , Szczęsny Waldemar , Marciniak Marian
Published: April 2024

In this paper we present results of an investigation into the power penalty introduced by Stimulated Raman Scattering (SRS) in WDM systems with concentration on application of dispersion-shifted single-mode optical fibres (G.653) and unequal channel allocation schemes. System parameters based on ITU-T Recommendation G.692 and analytic formulas were used in calculations. It is shown that SRS does present a practical limitation to the multichannel systems. We also indicate limitations of the G.692 Recommendation and we point at directions of study in the area of nonlinear phenomena and multichannel systems.

It has been shown that a simultaneous occurrence of both cases leads to an enhanced frequency shift.
Linear and nonlinear optical spectroscopy of CdS nanoparticles in Nafion membranes
Authors: Bourdin Emmanuel , Henari Fryod Z. , Blau Werner J. , Kelly John M.
Published: April 2024

CdS nanoparticles embedded in Nafion membranes were studied by a variety of optical spectroscopic methods. Quantum confinement was achieved (particle mean diameter of 40 A) and the growth was found to follow a linear temporal kinetic law. Discrete energy levels were observable, even at room temperature. They could be attributed to light hole and heavy hole 1S and 2S transitions. The experimental results are in good agreement with theoretical calculations of light hole and heavy hole masses in the cases of cubic CdS. An enhancement of the nonlinear susceptibility X(3) at the quantized exciton energy levels was observed. The clusters were found to be photo-unstable, with a diffusion-limited growth rate due to Ostwald ripening.
Optical Josephson effects using phase-conjugating mirrors: an analogy with superconductors
Authors: Blaauboer Miriam , Lenstra Daan , Lodder Adri
Published: April 2024

Motivated by the analogy between a phase-conjugating mirror (PCM) and a superconductor, we search for optical counterparts of the well-known DC and AC Josephson effects. We show that in a system consisting of two PCM`s separated by vacuum an ,,optical supercurrent`` arises as a function of an applied phase difference between the PCM`s, which is the optical analogue of the DC supercurrent flowing in a superconducting weak link. The corresponding AC effect occurs when the two PCM`s are pumped by light of a different frequency, causing the phase difference to oscillate in time with the frequency difference.

Published: April 2024

Reflective and transmitting properties of several layers of double-periodic arrays are studied. In the arrays, elements are conducting inclusions of various shapes. It is shown that in these structures all the phenomena recently found in dense wire grids with periodical defects (so-called photonic band gap structures) can be observed and explained in simple terms of inter-layer and inclusion resonances. Frequency-selective (with two and more stop bands) and polarization transformation properties of these arrays are demonstrated.

Published: April 2024

Abstract. In this exploration, we introduce a certain family of regular (or analytic) functions in association with the righthalf of the Lemniscate of Bernoulli and the well-known Opoola differential operator. For the regular function \(f\) studied in this work, some estimates for the early coefficients, Fekete-Szegö functionals and second and third Hankel determinants are established. Another established result is the sharp upper estimate of the third Hankel determinant for the inverse function \(f^{-1}\) of \(f\).
The German War in German Poetry: Julius Bab's Anthology of German First World War Poetry
Authors:   , Smith Roger
Published: April 2024

This dissertation examines Julius Bab’s twelve-volume anthology of German First World War poetry, 1914 Der deutsche Krieg im deutschen Gedicht (1914-1919). It argues that although Bab’s anthology and his contemporary reviews of war poetry laid the foundation for later research on German war literature, both Bab and his anthology have been mischaracterised in much recent scholarship as war-apologetic and merely providing a platform for pro-war propaganda. Such judgements fail to account for why Bab’s anthology, rather than any of the many others that were produced in Germany during the First World War, has persisted to this day as the key source for German poetry of the conflict. This dissertation describes the key features of Bab’s work that set it apart from the anthologies of his contemporaries, and which have given it such longevity. Proceeding via analysis of each of the volumes in order of publication, together with a closer reading of selected poems within each volume, it locates the anthology in the historical context in which it was compiled and first read, a time of unprecedented international conflict. Reading the anthology alongside Bab’s own commentaries on the poetry of the war, first published in the journal Das literarische Echo and later compiled into Die deutsche Kriegslyrik, 1914-1918: eine kritische Bibliographie (1920), this study reveals a rich and highly nuanced assemblage of poetry, which although highly regarded at the time, tends to be acknowledged only fleetingly and pejoratively in recent scholarship. It shows that Bab’s educated middleclass outlook informed his selections, and that the range of poets and poems he drew from was extraordinarily and deliberately broad: geographically, socially and politically. This study also shows why labels such as war propagandist and apologist fit Bab so poorly. The earliest volumes contain poetry that is at least equivocal if not anti-war. By the later volumes, much of the writing is overtly pacifist. If Bab is a propagandist in any sense, then he is a propagandist of German culture, because throughout his anthology he tirelessly asserts the continuity of the German literary tradition, and the place of the new war poetry within it. The significance of this study, the first full-length analysis of Bab’s anthology, lies in its reappraisal of a work which can enhance our understanding of the extraordinarily wide range of war poetry written and read in German during the conflict. It also reveals Bab’s own highly nuanced curatorial sense as an anthologist, who, over the full course of the war, was able to weave a compelling narrative from a polyphony of voices, and who in so doing created an important literary document of the conflict.
2-D ANALYTICAL SOLUTION OF SOLUTE TRANSPORT WITH DECAY-TYPE INPUT SOURCE ALONG GROUNDWATER
Authors: Dubey Arun
Published: April 2024

The stabilization of groundwater resources in excellent quality is crucial for both the environment and human societies. To examine the contaminant concentration pattern of infinite and semi-infinite aquifers, mathematical models provide accurate descriptions. The two-dimensional model for a semi-infinite heterogeneous porous medium with temporally dependent and space-dependent (degenerate form) dispersion coefficients for longitudinal and transverse directions is derived in this study. The Laplace Integral Transform Techniques (LITT) is used to find analytical solutions. The dispersion coefficient is considered the square of the velocity which represents the seasonal variation of the year in coastal/tropical regions. To demonstrate the solutions, the findings are presented graphically. Figures are drawn for different times for a function and discussed in the result and discussion section. It is also concluded that a two-dimensional model is more useful than a one-dimensional model for assessing aquifer contamination.

Authors: Türker Elif
Published: April 2024

Servet-i Fünun şiiri, bir beyanname ile ortaya çıkmış değildir. Recaizade Mahmut Ekrem’in, Muallim Naci ile girdiği “Abes-Muktebes” tartışmasının alevlenmesinden sonra Galatasaray Sultanisi’nden öğrencisi Ahmet İhsan’ın sahibi olduğu Servet-i Fünun dergisinin başına, yine aynı okuldan öğrencisi Tevfik Fikret’i getirmiş ve bu dergide benzer edebiyat anlayışına sahip gençlerin zamanla bir araya gelmesiyle Servet-i Fünun şiiri ortaya çıkmıştır. Burada, “benzer edebiyat anlayışına sahip” ifadesi kilit bir rol oynar. Bu benzerlik, bir grup oluşturacak nitelikte olmasının, genç okurlar arasında rağbet görmesinin yanı sıra tepki çekmesi ve bu nedenle eleştirilerin hedefi haline gelmesi bakımından da dikkat çekmektedir. Özellikle dönemin otorite yazarlarından Ahmet Mithat Efendi, Servet-i Fünun yazarlarını, Tanzimat Fermanı’yla resmiyet kazanan Batılılaşma sürecindeki çabalara zarar verdikleri yönünde eleştirir. Ahmet Mithat, Servet-i Fünun yazarlarını Fransa’da ortaya çıkan ve “geri gitme” anlamına gelen “Dekadan” hareketiyle özdeşleştirir. Servet-i Fünun yazarları bu eleştirilere sessiz kalmaz. Ahmet Mithat Efendi’nin eleştirilerinin hedefindeki Cenap Şahabettin de yanıt veren isimlerden olmasına rağmen hiçbir yazısında doğrudan yanıt verme amacı gütmez. Cenap Şahabettin bu eleştirileri daha çok Servet-i Fünun edebiyatının amacını / niyetini açıklamak için bir fırsat gibi görür. Bu çalışmada da, Servet-i Fünun şiirinin ortaya çıkışının yarattığı etki ve bu etkiye, bilhassa Cenap Şahabettin’in verdiği tepkiler üzerinden Servet-i Fünun şiirinin poetikası araştırılacaktır.
Çevirikurgu Eserlerde Neolojizm Çevirisi: Metinlerarasılık ve Çevirmen-Okur İşbirliği

Günümüzde hala değişen ve gelişen bir tür olarak bilimkurgu yeni sözcük ve terim üretimi olan neolojizmin en sık karşılaşıldığı türlerden biridir. Bilimkurgunun bir alt türü olarak değerlendirdiğimiz “transfiction” (Klaus Kaindl, 2011), Türkçe’de çevirikurgu eserlerin neolojizm açısından oldukça verimli olduğu düşünülmektedir. Bu tür eserlerde neolijizm çevirisinin çevirmeni farklı tekniklerin kullanımına yönlendirdiği görülmektedir. Bu çalışmanın amacı Kim Stanley Robinson'ın 2312 (2012) adlı çevirikurgu eserini inceleyerek neolojizm örneklerinde kullanılan çeviri tekniklerini çevirmen-okur işbirliği bağlamında ele almaktır. Çevirmen Mehmet İhsan Tatari tarafından çevrilen ve 2016 yılında yayınlanan bu eserin neolojizm açısından zengin olması nedeniyle araştırmamızın çevirikurgu çalışmaları literatürüne katkı sağlarken aynı zamanda neolojizm çalışmalarına da faydalı olacağı düşünülmektedir. Araştırmamızın kuramsal ve kavramsal çerçevesinde Gerard Genetté’in “metinlerarasılık” ve “yanmetinsellik” kavramlarının yanı sıra Umberto Eco’nun “örnek okur” kavramından yararlanılacaktır. Çalışmamızın yönteminde Lucia Molina ve Amparo Hurtado Albir (2018)’in ortak çalışmalarında öne sürdükleri neolojizm çevirisinde kullanılan tekniklerin sınıflandırılmasından faydalanılacaktır. Neolojizmler için kullanılan metinlerarası ya da göstergelerarası dipnotların okurla yapılan bir anlaşmanın varlığını ortaya çıkardığı düşünülmektedir. Hem yanmetinsel öğeler olarak hem de neolojizm çeviri tekniği olarak dipnot kullanımı sayesinde okurun kavram hakkında bilgilenmesine olanak sağlanırken aynı zamanda okurun başka metinlere de yönlendirilerek metinlerarası bir yolcuğa davet edildiği söylenebilir. Böylelikle çevirmen tarafından okura hem söz konusu kavrama dair gerekli açıklama ya da tanım sunulurken hem de onun kavramın kökenine inebilmesi ve özgün olanla çevirinin zenginliklerini eşit derecede göstermesi için bir fırsat olarak değerlendirilen bu çevirmen-okur işbirliği, metinlerarasılığın neolojizm çevirilerinde önemini açığa çıkarmaktadır kanısındayız.
Çeviri Çocuk Edebiyatı ve Mizah: “Bizim Matrak Sınıf” Serisinin Arapça Çevirilerinin İncelenmesi

Çeviri edebiyat eserleri, çocuklar için dışarıya açılan bir penceredir. Çeviri sayesinde çocuklar yabancı dünyayı ve başka kültürleri tanıyarak öğrendikleri yeni kültürle kendi dünyasını karşılaştırma fırsatı bulur. Mizah içeren edebî eserler, öğrenme işini en iyi eğlenerek ve gülerek yapan çocukların zihinsel ve ruhsal gelişimleri açısından da büyük önem arz etmektedir. Çocuklar kendi dünyaları dışında yabancı olan toplumların mizahlarını çeviri yoluyla öğrenmektedirler. Kültürel ve dilsel ögeler içermesi sebebiyle çocuk edebiyatında mizahın başka bir dile ve kültüre aktarılması son derece zordur. Çocuk edebiyatında mizahın aynı zamanda çocuğa göreliğin düşünülerek aktarılması gerekmektedir. Bu bağlamda çalışmada çocuk edebiyatındaki mizah unsurlarının çevirisi ele alınmıştır. Yusuf Asal’ın kaleme aldığı Bizim Matrak Sınıf adlı kitap serisinin Arapçaya çevirisinin incelendiği çalışmada kaynak metinlerde yer alan mizah unsurları Johnson (2010) tarafından geliştirilen resimli çocuk kitaplarındaki mizahi unsurları inceleme formuna göre belirlenmiştir. Ayrıca mizah unsurlarını aktarırken hangi çeviri stratejilerinin kullanıldığı incelenmiş ve çeviriler Newmark’ın (1988) eşdeğerlik yaklaşımı bağlamında değerlendirilmiştir. Çalışmada elde edilen bulgular doğrultusunda, mizah unsurlarının çok fazla dilsel ve kültürel referanslar içerdiği gözlemlenmiş, buna bağlı olarak çevirmenin pek çok yerde kültürel ve betimleyici eşdeğerliğe başvurmak durumunda kaldığı görünmüştür. Bu bağlamda mizah unsurlarının aktarımı sırasında sorunlar yaşandığı ve bunun kültürel mizah kayıplarına sebep olduğu saptanmıştır.

Necati Cumalı’nın Ay Büyürken Uyuyamam adlı eserindeki hikâyelerde kadının algılanma biçimlerini konu edinen bu çalışma, kadın tiplerini tasnif etmeyi ve hikâyelerde yer alan kadınları, bu tasnif bağlamında incelemeyi temel almıştır. Hikâyelerdeki kadınlar, taşra ekseninde erkek merkezli bir bakışla sunulurlar. Ötekine ait olan bakış, sahibini doyuma ulaştırma aracı hâline gelirken bakışa konu olan kadının giyimi, davranışları ve yaşayışı üzerinde de belirleyici bir etkiye sahip olur. Kadınlığa ilişkin rollerin dağılımı, erkekler tarafından tayin edilir ve kadınlık hâlleri içerisinde iyi ile kötünün sınırları da tıpkı kadının yazgısı gibi erkekler tarafından belirlenir. Kadınlar genellikle kendilerine verili olan durum karşısında bir kabullenme içerisindedirler. Taşra düzeninde kadınların hayatını sürdürebilmek için evlilik bağıyla bağlı bulundukları erkekler, onların karar verme yetisini ellerinden alır ve kadın bedeni üzerinde denetim sahibi olurlar. Kendisi için belirlenen edilgen rolü üstlenmeyerek aktif özne konumuna gelen kadınlar yadırganır ve olumsuz sıfatlarla yargılanır. Kadının algılanma biçimini ve konumunu belirleyen önemli bir etken de sahip olduğu erkeksi özelliklerdir. Yalnızca kadın kimliğiyle belirsiz ve edilgen bir nesne olarak algılanan kadın, taşrada erkeklerle özdeşleştirilen üretim faaliyetlerine emek yoluyla katkı sağladığı ölçüde özgürleşir. Toplumsal kurallar, para ve güce sahip olan kadınlar için aynı keskinlikle işlemez. Zayıf ve güçsüz olanlar, davranışları sonucunda katı yaptırımlara maruz kalıp cezalandırılırken güce ve paraya sahip olanlar için toplumsal yasalar esnetilir. Böylece güç ve iktidar ilişkisi, kadının algılanması sürecinde etkili olur. Bu çalışma, Cumalı’nın Ay Büyürken Uyuyamam’ındaki farklı kadın tiplerini ve bu kadınların algılanma biçimlerini belirleyen unsurları ele almayı amaçlamaktadır.
Modernleşen Kadın Portrelerinin “Kadıköyü’nün Romanı” ve “Ankara” Romanlarındaki İki Farklı Yansıması
Authors: Keflioğlu Engin
Published: April 2024

Tanzimat döneminin değişim dalgasının toplumun bütün katmanlarını etkisi altına almasıyla oluşan münazara alanlarından biri de kadının toplumdaki yeri olmuştur. Tanzimat dönemi, Batılılaşmanın getirdiği modernleşme süreci sırasında kadının toplumda üstleneceği rolün sınırlarının çizilmesi gerekliliğini de beraberinde getirmiştir. Eril bir biçimlendirmeyle kadının yeni dönemde rolünün belirlenmesi de çoğu zaman modernleşmeyle paralel bir zaman dilimi içinde oluşmuş, modernleşme ile kadının toplumsallaşması eş değer görülmüştür. Tanzimat yazarlarının kadının değişimi üzerine kurguladıkları modernleşme meselesi, aynı zamanda kadının modernleşmesinin yaratacağı psikolojik ve kültürel travmaların nasıl halledileceği sorununu da ortaya çıkarmıştır. Türk edebiyatının Cumhuriyet’e uzanan hafızasında bu problem, geleneksel ve modern ikilemi içinde farklı mecralarda süreklilikle yerini bulmuştur. Bu çalışmada, Safiye Erol’un “Kadıköyü’nün Romanı” ve Yakup Kadri’nin “Ankara” romanındaki kadın karakterlere yazarların bakışı ve roman içinde gerek dönem zihniyetlerinin gerek yazarların edebî kişiliklerinin romanlarına etkileri üzerine bir inceleme ortaya konulması hedeflenmiştir. İki romanda da belirginleşen aşk, özgürlük, aile, ideal kadın gibi kavramlar, kadına biçilen toplumsal ve geleneksel cinsiyet rollerini yansıtmakla beraber modernleşen dünyada değişen kadın kimliğinin yeniden tasarımı için yazarların başvurduğu konseptler olarak görülmektedir. Tanzimat döneminden bu yana kadın olgusundaki değişikliklerin bu romanlarda nasıl karşılık bulduğu ortaya konmaya çalışılarak iki roman üzerinden bir analiz yapılmıştır. Yazarların edebî kişiliklerinden romanlara, romandan da kadın karakterlere doğru bir geçiş yapılıp sonuç bölümünde iki roman üzerinden değerlendirmeler ortaya konmuştur.
Hiding Away The Ghost of AMITY: The Narrator’s Fake Endings as Screen Memories in Andrea Levy’s The Long Song (2010)
Authors: Erbakan Alican
Published: April 2024

Although studies on trauma have grown exponentially since 1990s with Trauma Studies, in different shapes and identities, trauma has been a part of personal and cultural space for much longer. After the formal recognition of post-traumatic stress disorder as an ailment that affects both the body and the mind, Trauma Studies has expanded to other fields of study including literature. Trauma studies in Literature is a movement that focuses on how trauma is handled in literature both thematically and functionally. Literature can play a performative role in its representation of trauma through literary and narrative devices. This essay aims to explore how Andre Levy imitates the effect of screen memories, which are a symptom of trauma, with her experimentation with metanarration in The Long Song (2010). Screen memories are essentially substitute memories which replace the traumatic events in memory. They are attempts of self-preservation of the mind. Levy’s narrator July tries to replace some traumatic parts of her life in her autobiographical story in order save herself the pain of reliving them through narration. This results in abrupt and unexpected endings to her story at two different parts of the novel, where she tries to break off the narration with a seemingly happy ending. However, her disputes with her son, Thomas, prove that there is more to the story as she picks the story back up only to reveal an increasingly painful and traumatic proceeding. Therefore, this makes her attempts to end the story prematurely screen memories that hide the traumatic truth, not from the reader, but from July herself through a self-imposed alienation from her previous life as a slave in a Jamaica sugar plantation.
Role of Computed Tomography in Age Estimation by Schmeling Method Using Analysis of Medial Clavicular Epiphysis
Authors: Zafar Sehrish
Published: April 2024

Background: Age estimation has acquired significance due to its application in migration to various countries and legal purposes. It is a big problem in underdeveloped and developing countries, where original and genuine birth records are not available due to non-hospital births. Its application in juvenile courts for legal proceedings is very important. Application of x ray in age estimation is not much reliable in some circumstances. Schmeling method is more precise for age estimation with the help of thin slice CT scan images of medial clavicular epiphysis. Objective: The objective of this study was to use the CT scan images for establishing the relationship between ossification of medial clavicular epiphysis (radiological age) and age estimation (chronological age) of individuals. Study Design: Retrospective study. Settings: Department of Radiology, FJMU/Sir Ganga Ram Hospital, Lahore Pakistan. Duration: January to June 2022. Methods: Total 136 good quality CT scan images of patients were retrospectively assessed in this study, having age bracket of 10 to 40 years, including both males and females without any previous history of clavicular trauma or bony deformity. The included CT scans were HRCT Chest and CT Chest with contrast. CT scans of all those patients with known malignancy, post-surgical or post traumatic history of clavicle, taking immunosuppressants or radiation treatment were not enrolled in this study. Results: Out of total 136 patients, 66 (48.53%) were females and 70 (51.47%) were males. We found that at the age of 21 years, clavicular epiphyseal ossification stage shifts from 3rd to 4th schmeling stage. Mean age for stage 1 was 11 years for males and 10.5 years for females, for stage 2 was 14 years for both males and females, for stage 3 it was 18.9 years for males and 18.5 years for females, stage 4 was 24.4 years for males and 25.1 years for females and stage 5 was 33.21 years for males and 34.3 years for females. Maximum number of patients were in stage 4 (27.21 %) and 5 (39.71%). Conclusion: Considering results of our study, we concluded that an individual aged 21 years or above shows clavicular epiphyseal ossification stage 4 (schmeling), while an individual aged less than 21 years show clavicular ossification stage 3(schmeling). Therefore, application of thin slice CT scan images of medial clavicular epiphysis has utmost legal importance for the age estimation. We recommend computed tomography as an accurate and non-invasive imaging modality for age estimation by analysis of medial clavicular epiphysis, using schmeling method.
