El urbanismo y los datos: oportunidades, riesgos y límites
Authors: Buhigas María , Sola-Morales Pau
Published: February 2023

La creciente complejidad de los procesos urbanos globales está poniendo a prueba la capacidad de los instrumentos urbanísticos y del conocimiento acumulado históricamente sobre la ciudad. Se hace cada vez más evidente la necesidad de ampliar las herramientas al uso, de revisar conceptos y de proponer nuevos enfoques. Este artículo reflexiona sobre cómo la capacidad de generar y analizar datos de las ciudades, y de los procesos que las conforman y modifican, de la mano de las nuevas tecnologías digitales, abre un campo infinito de posibilidades y oportunidades, no exento de riesgos y limitaciones a considerar.
A city is not a static tree: understanding urban areas through the lens of real-time behavioral data
Authors: Moro Esteban
Published: February 2023

Cities are the main ground on which our society and culture develop today and will develop in the future. Against the traditional understanding of cities as physical spaces mostly around our neighborhoods, recent use of large-scale mobility datasets has enabled the study of our behavior at unprecedented spatial and temporal scales, much beyond our static residential spaces. Here we show how it is possible to use these datasets to investigate the role that human behavior plays in traditional urban problems like segregation, public health, or epidemics. Apart from measuring or monitoring such problems in a more comprehensive way, the analysis of those large datasets using modern machine learning techniques or causality detection permits to unveil of the behavioral roots behind them. As a result, only by incorporating real-time behavioral data can we design more efficient policies or interventions to improve such critical societal issues in our urban areas.

Some recent work by Martin Fleischmann and Dani Arribas-Bel offers a chance to talk with them about data analysis applied to the study of the form and behaviour of our cities. Their reflections, from an academic perspective, suggest some valuable ideas about the opportunities of working with data, about the use of artificial intelligence in the study of urban fabrics and about the sense of responsibility of their work.
Does Context Matter? Vocabulary Learning Strategy Use in Second and Foreign Language Contexts
Authors: GÜL YILMAZ Vesile , ÇÖKER Berna
Published: February 2023

Vocabulary is of great importance in language learning. Using Vocabulary Learning Strategies (VLS) surely promotes vocabulary learning. The aim of the present study is to examine the role of language learning context (EFL and ESL) in Turkish graduate learners’ VLS use. A descriptive research design was employed in the study. The participants were recruited from two contexts, namely; ESL and EFL. The ESL participants were 49 Turkish graduate (masters or doctorate) learners in various departments at 21 universities in the UK while the EFL participants were 79 graduate students attending all-English departments at 27 Turkish universities. Study data were collected via ‘Vocabulary Learning Strategies Questionnaire’. Descriptive statistics, t test, analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) were utilized in the data analyses. Research results revealed a significant difference between ESL (the UK) and EFL (Turkey) learners’ VLS use in favour of EFL learners. However, gender and academic major were not found to have any significant effect on learners’ VLS use. Moreover, Discovery-Determination strategies were the most frequently used VLS group while Consolidation-Social strategies were the least frequently used category in both groups. VLS instruction should be considered in both contexts. Also, further research into the reasons why VLS use differs in the ESL and EFL contexts is suggested.

Published: February 2023

Bu çalışmada İstanbul Arkeoloji Müzesi, Yazma Eserler Bölümünde 256 numarada kayıtlı Enbiyâ-nâme isimli şu ana kadar çalışılmamış bir mesnevi tanıtılacaktır. Bu mesnevinin divanî kırması hattıyla kaleme alınmış bir manzum peygamberler kıssası (kısas-ı enbiya) olduğu görülmüştür. Söz konusu bu kısas-ı enbiya nüshasının müellif nüshası değil; müstensih nüshası olduğu da tespit edilmiştir. Eser, Eski Türkiye Türkçesi ile kaleme alınmıştır. Aynı zamanda eserin kelime kadrosu çok zengin olup eserde arkaik kelimelere oldukça fazla rastlanmaktadır. Bu yönüyle eser, Türk dili ve bu dilin tarihî gelişimi bakımından da kıymetlidir. Bu manzum kısas-ı enbiyada çeşitli surelerden üç yüzü aşkın ayetin orijinalleri yazıldıktan sonra Türkçe meal ve tefsirlerinin beyitler şeklinde verilmiş olması, İslamî ilimler (meal ve tefsir gibi) açısından da önemlidir. Aruzun “mefâ’îlün/mefâ’îlün/fe’ûlün” kalıbı ile yazılmış eserin, günümüzün mevcut bilgilerine göre manzum olarak yazılmış en eski Türkçe kısas-ı enbiya olma ihtimali yüksektir. Eser eksik ve dağınık olduğundan müellifi, telif tarihi, müstensihi ve istinsah tarihi bilinmemektedir. Eser, mevcut eksik haliyle otuz yedi peygamber ve başka şahıslar hakkında kıssalar anlatmaktadır. Yapıt, kısas-ı enbiya türünde mesnevi nazım biçimiyle yazılmış eğitici/öğretici bir eserdir. Yapılan inceleme sonucunda Enbiyâ-nâme adlı bu eserin Eski Türk edebiyatı, Eski Türk dili, İslamî edebiyat, peygamberler tarihi, leksikoloji vb. alanlar için değerli bir kaynak olduğu düşünülmektedir.

Authors: ŞENER Ramazan
Published: February 2023

Postmodernizm; yapısalcılık, postyapısalcılık, yapısökücülük gibi akımların da teorilerini içeren bir anlayıştır. Postmodernizmin ortaya çıkmasında İkinci Dünya Savaşı öncesi ve sonrasında tüm dünyada yaşanan olumsuzluklar, savaşın getirmiş olduğu yıkımlar ve kayıplar etkili olmuştur. Modernizmin akılcı, işlevsel yapısından sıkılan insanlar farklı arayışlar içine girmiş, bu durum da postmodernizmin oluşmasına zemin hazırlamıştır. Postmodernizm; ilk dönemlerinde felsefe, mimari, edebiyat ve güzel sanatlarda etkili olmuş, zamanla modernizmin etkili olduğu her yerde postmodernizmden söz edilmeye başlanmıştır.

Orhan Pamuk, postmodern tarzda romanlar kaleme alan Nobel ödüllü Türk yazarıdır. Bu çalışmada yazarın postmodern yaklaşımla 2016 yılında yayımlanan Kırmızı Saçlı Kadın isimli romanının içerik ve yapı yönünden tahlil denemesine yer verilecektir.
Eski ve Yeni Toplumsal Hareketlerin Psikolojik Etkileriyle İlgili İki Film: Kar Küreyici ve Dövüş Kulübü
Authors: DOĞANER Saygın Koray
Published: February 2023

1960’lardan sonra siyasi, sosyal, ekonomik yaşamın değişimi, beraberinde getirdiği sorunların ve bu sorunlara tepkilerin de değişimine neden olmuştur. Daha önce sınıfsal ya da ulusal hareketler olarak tanımlanan toplumsal hareketler, kapitalizmin küreselleşmesi ile birlikte, ulus ve sınıfı aşan bir karakter kazanmıştır. Toplum insanı değiştirdiği gibi insan da toplumu değiştirmekte ve karşılıklı bir dönüşüm gerçekleşmektedir. Dolayısıyla bir neden sonuç ilişkisinden bahsedebileceğimiz gibi etkileşim içerisinde olan bir yapıdan da söz edebiliriz. Bu sabit ve durağan olmayan yapının somut birer çıktıları olarak toplumsal dinamikler devreye girer. Tüm bu süreç ve hareketler toplumsal olayların oluşmasına olanak tanır. Sivil haklar, ifade özgürlüğü, öğrenci hareketleri, kadın hakları, ekoloji bilinci, barış isteği, antikapitalizm, nükleer enerji karşıtlığı gibi psikolojik, sosyolojik ve siyasi talepler, çağımızın insanı kadar sinemayı da meşgul etmiştir. Filmlerin ve film senaryolarının çok boyutlu yapısı sinemanın toplumbilimiyle ilişkisini açığa çıkartır. Sinema aracılığıyla toplumbilimi içerisinde var olan olayların, olguların ve hareketlerin mevcut yapısı belirginlik kazanır. Sinema kendi dili aracılığıyla gerçekleri ve toplumsal hareketleri seyirciye aktarır. Gerçekleşen aktarımın dinamik yapısı aracılığıyla filmlerin içeriği, içinde yaşanan zamanın inanç kalıpları, değer yargıları ortaya çıktığı gibi toplumsal meselelere karşı gösterilen tavırlar da görünür olur. Bu çalışmada genel olarak Dövüş Klübü (1999) ve Kar Küreyicisi (2013) filmlerinde toplumsal hareketlerin karakterini, sistem eleştirisinin psikolojik ve sosyolojik yönleri inceleyecektir. Özel olarak ise Kar Küreyicisi filminde eski toplumsal hareketlerin izlerini incelenirken Dövüş Klubü filminde tüketim kültürünün eleştirel yapısı araştırılacaktır.

Published: February 2023

Esta investigación se centra en aquellos filmes cuya trama viene marcada por el uso de un videojuego y lo que éste implica respecto a la concepción de los personajes, la estructura y la historia. Se observaron 29 producciones cinematográficas. Se realizó un análisis fílmico de carácter temático discursivo, con el objetivo de profundizar en los usos y conceptualizaciones que se derivan de esta intertextualidad. Los resultados muestran una heterogeneidad en la manera de utilizar el juego digital como aporte narrativo. Se reflexiona sobre sus diferentes implicaciones, especialmente con la relación entre realidad y ficción, el uso del avatar, la estructura y reglas, el concepto de tiempo, la figura del demiurgo, la lucha contra la tiranía y la audiencia. Se concluye que este tipo de películas puede suponer un subgénero propio y muy prometedor dentro de la ciencia ficción y de la fantasía.
Film Uyarlamalarında Bir Yerlileştirme Örneği: Badi
Authors: AKDAĞ Taha
Published: February 2023

Çeviribilimin dilbilimin bir alt dalı olarak kabul edildiği yıllarda Roman Jakobson’un (1959) çeviri için öne sürdüğü üçlü tanımlama ile birlikte alana dahil olan göstergeler arası çeviri -dilsel göstergelerin dilsel olmayan gösterge dizgeleri aracılığıyla yorumlanması- kavramı çeviribilimin araştırma alanlarını daha geniş bir yelpazeye ulaştırmıştır. Bu kavram ışığında bir romandan uyarlanan bir tiyatro oyunu ya da sinema filminin çeviribilim bakış açısıyla incelenmesi mümkün olmuştur. Daha sonra Gideon Toury’nin (1986) gösterge içi çeviri-kaynak ve erek metnin gösterge dizgesinin aynı olduğu çeviri- kavramıyla birlikte bu çalışmanın da çıkış noktası olan yabancı bir filmin yerli uyarlaması da çeviribilim açısından analiz edilebilir hale gelmiştir. Bu bağlamda bir gösterge içi çeviri örneği olarak Steven Spielberg’ün yönettiği 1982 yapımı E.T. the Extra-Terrestrial filminin Türkçe bir uyarlaması olan, 1984 yapımı Zafer Par’ın yönettiği Badi filmi, bu çalışma kapsamında kaynak filmi ile karşılaştırmalı bir biçimde incelenmiştir. Bu çalışmanın amacı erek filmde bulunan kültürel ögeleri Venuti’nin (2001) yerlileştirme stratejisi bağlamında incelemektir. Bu amaca yönelik olarak, erek filmde bulunan kültürel ögelerin saptanmasında Antonini’nin (2007) sınıflandırması temel alınmıştır. Söz konusu sınıflandırmanın seçilme sebebi bu sınıflandırmanın Antonini tarafından sinemadaki kültürel ögelerin aktarılmasında kullanılmış olmasıdır. Biri Hollywood tarihinde, diğeri ise Yeşilçam tarihinde önemli bir yere sahip olan bu iki filmin çözümlenmesi sonucunda E.T. the Extra-Terrestrial filminin Badi filmine çevrilmesi sürecinde yerlileştirme stratejisinin kullanıldığı çok sayıda örneğe ulaşılmıştır.
A Carnivalesque Reading of The Turkish Translation of Dr Jekyll and Mr Hyde
Authors: İPLİKÇİ ÖZDEN Ayşenur
Published: February 2023

Mikhail Bakhtin, a prominent Russian philosopher of the 20th century, contributed to the field of philology and literary studies by propounding conceptions in several domains one of which is the foremost term ‘carnivalesque’. As it is a locution related to the ‘carnival’, it is of utmost significance to define this term. The ‘carnival’, deriving from the Lantern period at the time of the Romans, is a phenomenon in which all the rules in our daily lives, restrictions, regulations, and hierarchical forms are put aside; everyone is free and there are no restrictions in this sphere. The aim of this study is to read and analyse the Turkish translation of Robert Louis Stevenson’s The Strange Case of Dr Jekyll and Mr Hyde – with its full name –in the light of Bakhtin’s carnivalesque approach, and the Turkish translation of the work is evaluated particularly by taking Bakhtin’s main categories of the term ‘carnivalesque’, which are free and familiar interaction between people, eccentric behaviour by which the human nature in the work is revealed, and carnivalistic misalliances, all of which are considered to be abstract notions of freedom and equality. While taking the carnivalesque way of thinking into consideration, specifically the diverse characteristics of the protagonist in the novel are brought forth such as being respectable and well-liked but also hideous and depraved in conformity with the free and unrestricted world of the carnival.
Competitive Coexistence and Institutional Balancing of the US: Analyzing the formation of the US-led bespoke and ad hoc coalition and regional architecture
Authors:   The Korean Association Of Area Studies, Chung Kuyoun
Published: February 2023

This study analyzes the nature of US-China competition which is conceptualized as competitive coexistence in its attempt to examine the condition under which the US-led bespoke and ad hoc coalitions are established. The current US-China competition, which is characterized by changing balance of power and deepening interdependence, is allowing hedging behavior among regional countries. The US, which seek to form a favorable balance of power vis-a-vis China, attempts institutional balancing, building a multi-layered regional architecture with its through engaging regional countries. However, the distribution of varying interests and threat perceptions among regional countries makes the US difficult blocize the coherent supporting coalition as in the Cold War. Instead, it leads to the emergence of a bespoke and ad hoc coalition with its informality and institutional flexibility. Meanwhile, given these coalitions are being formed to meet specific goals such as interests, values, and threats, it remains unclear whether they can be properly utilized for the purpose of balancing China at a critical moment. As in the case of the Quad, it might be difficult to expand the mission beyond the originally agreed upon goal. Hence, the expanded role of balancing among these coalitions need to be observed in the future.
A ‘Balancing Act’ Between Development Impacts and National Interests: a Case Study of Japan’s Private Sector Investment Finance
Authors:   The Korean Association Of Area Studies, Kim Soyeun
Published: February 2023

The paper aims to explore how the so-called ‘innovative development finance’ emerged as a key agenda for the successful fulfilment of Sustainable Development Goals. In doing so, the study focuses on how such an agenda has been locally institutionalised and promoted as part of traditional donors’ geoeconomic and geopolitical strategies. Via a case study of Japan International Cooperation Agency (JICA)’s Private Sector Investment Fund (PSIF), the paper investigates how the resumption of PSIF was largely conditioned and driven by Japan’s new growth strategy that reiterated the effective use of ODA 1) as a catalyst for mobilising and leveraging bankable investments in developing countries, 2) to fend off fierce competition from China over infrastructure lending in Asia. Subsequently, Japan’s geoeconomic strategy further rendered its ODA more susceptible to instrumentalisation and financialised. In terms of implementing PSIF, JICA has been facing ample challenges in ensuring both Japan’s national interests and developing countries’ development needs equally – hence, careful balancing between them seems arduous. Such difficulties lie in actually formulating projects in developing countries via PSIF that 1) are bankable, 2) are clearly aligned development needs or priorities of host countries, 3) create added value/or additionally in the realm of development cooperation. These challenges reflect the urgency for further debates on critical, fundamental and principled questions concerning development finance in practice.
Russia-Ukraine War: An Analysis from the Perspective of Nuclear Competition
Authors:   The Korean Association Of Area Studies, Yang Hee-Yong
Published: February 2023

When we approach Russia-Ukraine War with the perspective of nuclear competition, relentless competition, driven by typical security dilemma, to achieve nuclear superiority is found to be strongly implicated before, during, and after the war. After the post-Cold War order emerged, the U.S. attempted to gain nuclear superiority over Russia by establishing theater missile defense system across Europe. Threat perception coming from the fear of its nuclear deterrence being undermined by America’s damage limitation strategy forced Russia to modernize its nuclear forces and extend the scope of nuclear deterrence to include the possible use of nuclear weapons even against conventional attacks. While Putin raising the prospect of using nuclear weapons invaded Ukraine, the U.S. response seemed to be constrained by the fear of nuclear escalation. Russia-Ukraine War has found 1994 Budapest Memorandum to be nothing more than empty statements and has awakened the world to the reality that nuclear threats are actively being used as a tool of intimation and escalation management. As such, Russia-Ukraine War has ushered us into “New Nuclear World” characterized by (1) the nuclear paradigm shift from non-proliferation to nuclear competition, (2) retreat of nuclear arms control regime, (3) and tripolar (U.S., Russia, and China) nuclear dynamics.
A Study on Changes in North Korea's Maritime and Port Legislation
Authors:   The Korean Association Of Area Studies, Chae Sulan
Published: February 2023

The purpose of this study is to find out the implications of the revision of North Korea's Maritime and Port Law for the North Korean economy. North Korea's Maritime and Port Law was classified into three periods, and looked into two frameworks: characteristics of North Korean law and compliance with international norms.
As a result, North Korea's shipping and port legislation presupposes international trade, so it was created within the framework of international convention from the beginning of its origin. Regardless of the time period, North Korea recognized the shipping and port industry as an important sector for economic growth, and reformed its laws to accept international norms in order to open its economy to the outside world. In addition, policy changes were made according to changes in the internal and external environment, and a causal relationship was shown in which changes in shipping and port laws were accompanied within the framework.
The enactment and revision of the Shipping and Port Act in the 2010s, a period of expansion of economic opening to foreign countries, was more systematized and concrete compared to the previous period, and the law was reformed in the direction of mitigating discrimination against foreign ships and crew, objectivity, efficiency, and simplification of administration.
However, in order to achieve a virtuous cycle structure in which law revision leads to industrial development, it is necessary to move towards market socialism through fundamental economic and institutional reforms.

Things and Theatricality
Authors: Peterson Lesley
Published: February 2023

This essay considers consider four of James Austen’s early prologues and epilogues (written for family theatricals between the ages of seventeen and twenty-two) in terms of his engagement with debates both ancient and early modern over the nature of drama and the place of spectacle. More specifically, these paratexts document his ongoing concern with theorizing the ideal theatre: one in which the things of the stage serve their proper role.  The discourse of antitheatricality has long associated theatrical performance with such unvirtuous qualities as artifice, dishonesty, and deception, and in his "Prologue to the Tragedy of Matilda" (1782), Austen associates the concrete objects of the stage with all that should be feared and devalued: pure, ancient theatre has been degraded by such things as the “scene gay painted” and the “canvas Palace” (8, l. 3, 5). In his "Prologue to The Rivals" (1784), by contrast, the things that signify theatrical artifice—the mask, the painted scene—are only metaphorical and thus innocuous. By 1788 Austen comes to see theatrical performance as a sign of English virtue, associated with the Restoration when “Charles, & loyalty & wit returned” (“Prologue to The Wonder,” 1788, l. 40) and reframes the "things" of the stage as objects made sacred by tradition and, specifically by association with the Christmas season.
Improving the Mechanical Properties of a Composite material Reinforced with Glass Carbon for Aircraft Application
Authors: Abed Khuder , Faris Saad , Naemah Iman
Published: February 2023

Abstract

The purpose of this research is to investigate how the fiber orientation and loading axis of a composite material affect its behavior. Consideration was given to two different fiber-to-matrix ratios in order to improve the mechanical properties. Hand lay-up samples were produced in accordance with ASTM D790 for flexural testing. On UTM, tensile and flexural tests were performed on the sample. The effect of fiber orientation modifies the composites' mechanical properties. As the fiber orientation increased, the tensile strength of the composite would reduce. This carbon/epoxy composite test demonstrates better strength than those conducted at (30, 5, 60, and 90 degrees). For flexural tests, a three-point bend at 30 degrees demonstrates excellent strength. Utilizing the three-point bend method, the flexural strength and flexural modulus have been determined. The tensile strength, young's modulus, elongation percentage, maximum load to break the composite, peak load, and flexural strength of single- and double-layered carbon fibers were compared and examined. As the number of layers increased, the adhesion between layers of epoxy and fiber carbon, and glass fiber weakened, causing a decrease in almost all mechanical properties. The fabricated 2024-T3 and epoxy glass fiber had higher fatigue strength than aramid reinforced and lower density than steel alloy utilized in aircraft manufacture.

Design and Performance Investigation of Intensity Modulation/Direct Detection Scheme for C- and O-band Point-to-Multipoint Optical Networks
Authors: Saadi Ali , Sami Raad
Published: February 2023

The fifth generation (5G) and beyond mobile networks support increasing number of users with increasing bit rate per users. This has encouraged researchers to propose coherent digital subcarrier multiplexing (SCM) point-to-multipoint (P2MP) architectures to reduce the cost and complexity of optical transport networks, particularly in the metro aggregation scenario. However, coherent optical receiver is relatively costly and complexity compared with a   direct-detection (DD) counterpart due to the use of a synchronized local laser. This paper addresses design issues and performance investigation of intensity modulation/direct-detection (IM/DD) P2MP optical networks. P2MP architectures are designed using digital RF multisubcarrier (MSC) waveform embedded on the intensity of continuous-wave (CW) laser beside direct-detection scheme. The design covers C- and O-band operation using a wavelength-division multiplexing (WDM) architecture. Further single- and double-polarization (SP and DP) versions are reported for each type of the networks. All the architectures are built in Optisystem version 15 environment and simulated for different network parameters, under the assumption of 25 Gbps per subcarrier data rate. The main performance measures are maximum route reach and bit rate-distance product (BDP). The simulation results indicate that DD networks can replaced the coherent counterpart when number of subcarriers per optical channel is 4. Further, the O-band P2MP networks offer high values of maximum reach and BDP than C-band counterparts.
Results of myxomycete experiments could be affected by temperature in “standard” laboratory conditions
Authors: Rojas Carlos , Valverde Randall
Published: February 2023

Moist chamber cultures are valuable for myxomycete research and can be used for the analysis of ecological patterns with implications in ecosystem conservation programs. However, to make comparisons between datasets valid, the method should be redesigned considering potential biases affecting the generation of results. In the present study, both the effect of the general climate of the laboratory and two microclimatic variables within the moist chamber were studied in relation with the obtained data. Of all the recorded variables, temperature was observed to affect the results, both at the level of the general laboratory climate and in relation with the microclimate of the moist chamber. Increments in laboratory and moist chamber temperature increased the probability, three or fourfold, associated with a higher number of records or species within a group of equivalent samples. Such probabilistic differences are significant enough to suggest that using the moist chamber technique in “standard” laboratory conditions is not enough for cross-dataset comparisons that increase the potential of myxomycete data for applications outside of the biological sciences.
INVASIVE LOBULAR BREAST CANCER METASTATIC TO THE ORBIT: A CASE REPORT
Authors: Lemos Nathalia Oliveira , Bagnoli Fábio , Silva Maria Antonieta Longo Galvão , Rinaldi José Francisco , Oliveira Vilmar Marques de
Published: February 2023

Invasive lobular carcinoma represents 5%–15% of breast carcinomas, presenting in many cases as multicentric and bilateral tumors with low mammographic detection. The most common breast cancer metastases are the bones, lungs, brain, and liver. However, the disease can also spread to abdominal cavity, ovaries, and skin. The orbit is an infrequent site of tumor metastasis, ranging from 1% to 13% among all orbital tumors, and breast, lung, and prostate are among the most common primary sites. We report the case of a 73-year-old female patient who presented with a palpable mass in the left orbital rim, whose incisional biopsy revealed a pattern compatible with invasive breast carcinoma with lobular characteristics and E-cadherin overexpression, luminal molecular subtype B. She denied breast complaints and palpable nodules, but on clinical examination she showed a tumor in the inferolateral quadrant of the left breast measuring 6 cm and a left axilla with lymph node enlargement suspected of lymph node involvement. Mammography identified suspicious nodulation in this topography, confirmed by ultrasound. The diagnosis made through core biopsy was an invasive breast carcinoma with lobular characteristics, and the immunohistochemical profile showed luminal molecular subtype B. Systemic staging revealed involvement of the retroperitoneum, left ovarian annex, vertebral bodies, pelvis, right femur, and left iliac suspected for secondary involvement. The patient is currently undergoing adjuvant systemic treatment.

Published: February 2023

Objective: The aim of this study was to verify the response to CO2 laser therapy regarding vaginal dryness in women submitted to this treatment in a facility in the state of Minas Gerais, Brazil. Methods: This is a prospective descriptive case series based on patients treated by the same team with the same Monalisa device of the Beker company. The treatment consisted of three sessions, adopting the same energy and pulse pattern from January 2019 to December 2021, with records of predefined information and the use of the R and SPSS PC software for data analysis. Results: A total of 92 women with a mean age of 60.3 years +10.6 (ranging from 28 to 92 years) were treated in the facility for vaginal dryness. Vaginal dryness improved in 94.6% of cases. Sex life improved in 81% of cases, and sexual intercourse increased by 66%. They would all recommend the examination to a friend. We found no statistical significance for the use of tamoxifen (12 cases), anastrozole (8 cases), previous chemotherapy (27 cases), and time between surgery and laser therapy (p>0.05). Conclusion: The study shows good results, with CO2 laser therapy improving vaginal dryness and sex life; however, the sample limitation prevents the statistical analysis of subgroups.
POSITIVE PREDICTIVE VALUES OF THE BREAST IMAGING REPORTING AND DATA SYSTEM (BI-RADS®) CATEGORIES 4, 5, AND 0 IN MAMMOGRAPHY AND ULTRASOUND EXAMINATIONS: ANALYSIS BASED ON LOCAL CLINICAL PRACTICE
Authors: Almleida João Ricardo Maltez de , Fonseca Natália Rezende , Chagas Gabriela Lemos , Duran Daniel Cendon , Hassan Augusto Tufi
Published: February 2023

Introduction: The American College of Radiology (ACR) BI-RADS specifies different approaches to calculating positive predictive values (PPVs) of screening/diagnostic tests. The biopsy yield of malignancy based on tissue diagnosis (PPV3) is considered the most accurate indicator of cancer status. Nevertheless, in routine clinical practice, Brazilian physicians frequently take conduct grounded only on cytopathology and clinical follow-up, which might introduce bias when interpreting BI-RADS-derived metrics of performance. Objectives: This study aimed to analyze the PPV of BI-RADS categories 4 and 5 in mammography and ultrasound studies in a local reference outpatient clinic. The results from inconclusive examinations (category 0) and the PPV of BI-RADS 4 subcategories were also investigated. Methods: Retrospective analysis of the BI-RADS classification applied to mammography and ultrasound studies performed during October (Breast Awareness Cancer Month) from 2009 to 2013. We calculated the PPV for BI-RADS categories 4 (also for subcategories 4A, 4B, and 4C), 5, and 0, considering not only biopsies performed, but also cytopathologic studies and follow-up as a composite outcome measure. χ2 and other pertinent statistical tests were used on SPSS, version 20. Results: After exclusion criteria were applied, the study sample was composed of 734 women with a mean age of 55.74 years (SD=12.59). Of the participants, 469 (63.9%) had both studies, 136 (18.5%) had only mammography, and 129 (17.6%) exclusively had ultrasound. The PPV for category 4 in mammography was 29.2% (38/130), for category 5 was 100.0% (6/6), and 2.3% for category 0 (9/391). BI-RADS 4 in ultrasound had a PPV of 13.5% (35/260), 100% for BI-RADS 5 (6/6), and 20% (1/5) when BI-RADS 0 was used. The PPV for each subcategory of suspicious lesions found on mammography was 13.6% (11/81) for BI-RADS 4A, 40% (10/25) for 4B, 83.3% (15/18) for 4C, and 4.6% (6/130) of the studies were not subcategorized. On ultrasound, the PPV for subcategory 4A was 4.7% (8/172), 42.9% (3/7) for 4B, 100% for 4C (12/12), and 26.5% (69/260) examinations were not stratified. The different subcategories for both methods showed a statistically significant association with malignant outcomes using the χ2 test (p <0.005). Conclusion: Most of the PPVs observed were similar to the ACR BI-RADS benchmarks and other values reported in the scientific literature, even considering the broader outcome measure studied (tissue sampling, cytopathology, and follow-up). Nevertheless, some of the variations observed merit further study, since we employed an unusual composite outcome measure that might partially explain our findings and is more closely related to current clinical practice in Brazil.
RECURRENT PHYLLODES TUMOR MALIGNANCY: A CASE REPORT
Authors: Camacho Ana Thereza da Cunha Uchoa , Rodrigues Ana Paula Pontes , Peixoto Maria Clara Sousa , França Rebeca de Sousa , Silva Lívia Nazaré Soares
Published: February 2023

Fibroepithelial tumors of the breast are part of a heterogeneous group of biphasic neoplasms, which include common fibroadenomas (FA) and phyllodes tumors (PTs). The PT is a rare fibroepithelial tumor that is histologically divided into three grades: benign, malignant, or borderline. Although only about 10% of these tumors are malignant, even benign tumors are prone to local recurrence and can become very large in size. The standard management of PT is surgical excision with negative surgical margins, due to the propensity for local recurrence. Therefore, the report about this type of tumor with multiple recurrences and malignization in the same person is important for the literature. A female patient, 30 years old, without comorbidities, with an obstetrical history of an abortion due to anembryonic egg and with a previous oncological history of four left breast segmental resections for the removal of solid nodules, confirmed anatomopathologically as borderline PT, benign PT, FA, and benign PT, respectively, in the years 2017, 2018, 2018, and 2019, was observed. No intercurrences were noted in the follow-up with a mastologist who found, in the physical examination, the presence of nodules and a palpable left breast, which caused discomfort when lying in the left decubitus position, with painless, nonsecretive, without palpable lymph nodes, and with accelerated growth. Ultrasonography revealed the presence of simple cysts in the right breast and two solid nodules BI-RADS 4 compatible with the diagnostic hypothesis of PT; therefore, surgical resection was indicated. However, with the increase in the volume of the nodules, it was not possible to obtain free margins and a simple mastectomy was chosen. On November 11, 2021, a left mastectomy was performed with partial resection of the pectoralis major muscle due to an intraoperative infiltrative lesion and immediate breast reconstruction with the placement of silicone prosthesis, without complications. In the anatomopathological examination, a malignant PT was identified with an infiltrative border pattern and the presence of neoplastic infiltration in the underlying skeletal muscle tissue. On December 23, 2021, the oncologist informed that the CT-PET performed days before denoted the absence of sites suggestive of a neoplastic process and the presence of a probable inflammatory scarring process in the left breast around the breast prosthesis. She is currently being followed up by the mastologist and the oncologist, through imagining examinations together with the clinical consultation, without the use of chemotherapies.

M.C.V., 54 years old, born in Presidente Bernardes, Minas Gerais, was admitted on September 10, 2018, with a palpable abnormality in the right breast, a 15-mm heterogeneous lobular nodule in the junction of the right upper quadrants (BI-RADS 5). Mammography showed focal asymmetry in the same location (BI-RADS 0). She was submitted to ultrasound-guided core-needle biopsy with a result of invasive ductal carcinoma — grade 3. The immunohistochemical pattern revealed positive estrogen and progesterone receptors, C-ERB B2 with a +2 score, and 20% Ki67 positive. The FISH test was negative. The patient refused treatment, returning to the facility on August 14, 2019, with a normal physical examination. Ultrasound showed an 8 mm lesion in the junction of the right upper quadrants (BI-RADS 6), while mammography indicated focal asymmetry regression. A staging study was performed with chest x-ray, abdominal ultrasound, and normal bone scan. Laboratory study was normal, except for a high total IgE level of 4,290. She underwent segmental resection and sentinel lymph node biopsy in the right breast on August 17, 2019, at the Hospital São Vicente de Paula, Ubá/ Minas Gerais, with the histological result revealing a 9-mm invasive lobular carcinoma, free margins, and negative sentinel lymph node. The treatment indicated was radiotherapy and the use of 20 mg tamoxifen for 5 years. We conclude that there is something different, possibly associated with the high IgE level, which we will continue to study to understand.

The lesions of uncertain malignant potential of the breast, classified as B3, besides increasing the relative risk for breast cancer, have very heterogeneous abnormalities and raise a big question when defining conduct. A good multidisciplinary evaluation is necessary, comparing biopsy and imaging examination results. This study reports the case of a 54-year-old patient, without other risk factors for breast cancer, who was referred to MAMARJ, a mastology clinic, from a gynecology service, in November 2019 for evaluation of category 4 mammography, due to alterations in the right breast: linear and heterogeneous calcifications in the upper outer quadrant (UOQ) and punctiform and grouped calcifications lower inner quadrant (LIQ). Mammotomies were indicated, and histopathological reports were compatible with columnar cell hyperplasia with a focus on planar atypia — in the UOQ — and adenomyoepithelioma and columnar cell hyperplasia without atypia — in the LIQ. She was taken to surgery to remove the lesion from the UOQ (histopathology without malignancy). In July 2020, she underwent a mammography with a category 2 (BIRADS) report due to parenchymal distortion from previous surgery, and a ultrasonography with sparse cysts and bilateral ductal ectasia (category 3). One year later, in July 2021, she presented mammography — amorphous calcifications in the upper quadrants and punctate calcifications in the LIQ, near the clip from previous mammotomy. A mammotomy of the calcifications in the upper quadrants was performed. The diagnosis of the vacuum-guided biopsy was columnar cell changes with minimal architectural atypia in the upper quadrants. Removal of the lesion from the upper quadrants and the LIQ (target of the previous mammotomy) was indicated. The histopathological diagnosis was ductal carcinoma in situ (LIQ), associated with an atypical ductal hyperplasia, microcalcifications, and flat epithelial atypia. Immunohistochemical panel: estrogen receptor (ER) was positive, progesterone receptor (PR) was positive, and human epidermal growth factor receptor type 2 (HER2) was negative. The upper quadrant lesion was compatible with a focus on intraductal proliferation with discrete atypia. A simple mastectomy was performed with immediate reconstruction in the right breast. The mastectomy was indicated mainly because it was the patient’s choice. As suggested, since the first diagnosis of B3 lesion and after that of ductal carcinoma in situ, the patient did not accept chemoprevention. It should be noted that risk-reducing mastectomy is cited only rarely for the prevention in cases of even recurrent and multicentric premalignant lesions, as in this case.
