Authors: Muftah Elfaidy Yusra , Abdalla Elnaihoum Warida , Abdullah Elgotrany Aseidah
Published: December 2023

Background: Management of partially edentulous patients with hard and soft tissue undercuts is complicated, and the use of flexible dentures for these cases offers dual advantages of aesthetics and flexibility. However, research shows a varying preference for flexible dentures among general dental practitioners, prosthodontists, and other dental specialties.

Objectives: The aim of this study was to survey the attitude and awareness of a sample of Libyan dental clinicians towards advantages, disadvantages, indications, and contraindications of flexible dentures.

Material and methods: A descriptive cross-sectional study was conducted among 250 dentists currently practicing in different cities of Libya. Only 218 dentists responded. Using Google form software, a self-administrable e-questionnaire consisting of thirty-one multiple choice questions with “yes,” “no” or “not sure” answers encompassing major aspects of flexible dentures was conducted through an online survey.

Results: Out of 250 Libyan dentists to whom the questionnaire was sent, only 218 dentists responded and our results revealed that the respondents were females more than males with a ratio (2:1) and more than half of them were of age group (35-60 years) work in governmental dental practice with more than ten years of experience and 34.9% of them prefer and often offer flexible dentures to their patients. The majority of respondents with a long-term success of the flexible denture were prosthodontists who had more than ten years of experience with a correct response rate of more than 50% of questions that reflected their attitude and knowledge.

Conclusions: Despite the fact that flexible dentures are not taught in Libyan universities of dentistry, about more than one-third of respondents prefer and recommend this treatment to their patients, and the long-term success of these prostheses was dependent on clinicians’ education and their clinical experience.

Authors: Elmenfy Tawfiq , Abdelsalam Samah
Published: December 2023

Power system stabilizer (PSS) is used to damping power system oscillation. It will act as supplementary feedback through the generator excitation system, which produce a component of electrical torque in phase with speed variation. Fuzzy controllers are nonlinear. It is more difficult to set the fuzzy controller gains compared to conventional PID controller. This research proposed velocity (PID-FPSS) its gains are tuned by particle swarm optimization technique (PSO). The objective is to damp local-area oscillation that occur following power system small or large disturbances. The effectiveness of the proposed technique is illustrated by applying the velocity PID-FPSS to a single-machine infinite bus power system that is typically used in the literature to test the performance of power system stabilizers. The simulation has been conducted in MATLAB, SIMULINK (R2013a) package.   A comparison between the proposed PID-FPSS and a well-designed robust power system stabilizer (RPSS) confirms the superiority of the proposed technique.

BACKGROUND

Barrett’s esophagus (BE), which has increased in prevalence worldwide, is a precursor for esophageal adenocarcinoma. Although there is a gap in the detection rates between endoscopic BE and histological BE in current research, we trained our artificial intelligence (AI) system with images of endoscopic BE and tested the system with images of histological BE.

AIM

To assess whether an AI system can aid in the detection of BE in our setting.

METHODS

Endoscopic narrow-band imaging (NBI) was collected from Chung Shan Medical University Hospital and Changhua Christian Hospital, resulting in 724 cases, with 86 patients having pathological results. Three senior endoscopists, who were instructing physicians of the Digestive Endoscopy Society of Taiwan, independently annotated the images in the development set to determine whether each image was classified as an endoscopic BE. The test set consisted of 160 endoscopic images of 86 cases with histological results.

RESULTS

Six pre-trained models were compared, and EfficientNetV2B2 (accuracy [ACC]: 0.8) was selected as the backbone architecture for further evaluation due to better ACC results. In the final test, the AI system correctly identified 66 of 70 cases of BE and 85 of 90 cases without BE, resulting in an ACC of 94.37%.

CONCLUSION

Our AI system, which was trained by NBI of endoscopic BE, can adequately predict endoscopic images of histological BE. The ACC, sensitivity, and specificity are 94.37%, 94.29%, and 94.44%, respectively.

Published: December 2023

BACKGROUND

Endoscopic evaluation in diagnosing and managing ulcerative colitis (UC) is becoming increasingly important. Several endoscopic scoring systems have been established, including the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) score and Mayo Endoscopic Subscore (MES). Furthermore, the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting (TIGER) score for UC has recently been proposed; however, its clinical value remains unclear.

AIM

To investigate the clinical value of the TIGER score in UC by comparing it with the UCEIS score and MES.

METHODS

This retrospective study included 166 patients with UC who underwent total colonoscopy between January 2017 and March 2023 at the Affiliated Hospital of Qingdao University (Qingdao, China). We retrospectively analysed endoscopic scores, laboratory and clinical data, treatment, and readmissions within 1 year. Spearman’s rank correlation coefficient, receiver operating characteristic curve, and univariate and multivariable logistic regression analyses were performed using IBM SPSS Statistics for Windows, version 26.0 (IBM Corp., Armonk, NY, United States) and GraphPad Prism version 9.0.0 for Windows (GraphPad Software, Boston, Massachusetts, United States).

RESULTS

The TIGER score significantly correlated with the UCEIS score and MES (r = 0.721, 0.626, both P < 0.001), showed good differentiating values for clinical severity among mild, moderate, and severe UC [8 (4–112.75) vs 210 (109–219) vs 328 (219–426), all P < 0.001], and exhibited predictive value in diagnosing patients with severe UC [area under the curve (AUC) = 0.897, P < 0.001]. Additionally, the TIGER (r = 0.639, 0,551, 0.488, 0.376, all P < 0.001) and UCEIS scores (r = 0.622, 0,540, 0.494, and 0.375, all P < 0.001) showed stronger correlations with laboratory and clinical parameters, including C-reactive protein, erythrocyte sedimentation rate, length of hospitalisation, and hospitalisation costs, than MES (r = 0.509, 0,351, 0.339, and 0.270, all P < 0.001). The TIGER score showed the best predictability for patients' recent advanced treatment, including systemic corticosteroids, biologics, or immunomodulators (AUC = 0.848, P < 0.001) and 1-year readmission (AUC = 0.700, P < 0.001) compared with the UCEIS score (AUC = 0.762, P < 0.001; 0.627, P < 0.05) and MES (AUC = 0.684, P < 0.001; 0.578, P = 0.132). Furthermore, a TIGER score of ≥ 317 was identified as an independent risk factor for advanced UC treatment (P = 0.011).

CONCLUSION

The TIGER score may be superior to the UCIES score and MES in improving the accuracy of clinical disease severity assessment, guiding therapeutic decision-making, and predicting short-term prognosis.
A systemic fungicide might reduce the male genitalia of a stingless bee species by one-third
Authors: Ramos Jenifer D. , Santos Charles F. , Cristmann Luisa , Blochtein Betina
Published: December 2023

Bees are essential pollinating insects that significantly contribute to crop production. However, the use of pesticides in modern agriculture has resulted in bees being exposed to a plethora of harmful substances. Larvae of bees are particularly susceptible to exposure, as they can consume contaminated larval food during development. This study opportunely examined the effects of fungicides and insecticides on the size and shape of the genitalia of Scaptotrigona bipunctata (Lepeletier, 1836) males (Hymenoptera: Apidae: Meliponini) during larval development when experimental design was structured to obtain female bees (workers). Therefore, the geometric morphometric analyses were based on male bees that opportunistically emerged. Our findings showed a significant difference in the size of the genitalia of S. bipunctata males exposed to a systemic fungicide during larval development, while the genital shape remained similar. Although the exact impact of these morphological changes on the reproductive success of S. bipunctata males is uncertain, they suggest an adverse effect of pesticides on bees.
Analysis of Plasmids of the Klebsiella pneumoniae Complex Carrying a Cluster of Aerobactin Synthesis Genes as Presented in International Databases
Authors: Shapovalova V. V. , Chulkova Р. S. , Ageevets V. A.
Published: December 2023

Background. Currently, it is customary to distinguish two pathotypes of Klebsiella pneumoniae — classical and hypervirulent, which have the ability to cause community-acquired infections in healthy people. It has been shown that an increase in virulence is associated with the acquisition of additional genetic material — a plasmid carrying a cluster of aerobactin genes. Aim. To assess the prevalence of the aforementioned virulent plasmids around the globe and in Russia in particular, as well as to identify their key genetic features. Materials and methods. Plasmid sequences were downloaded from PLSDB and BV-BRC databases, annotated with the Abricate and Kleborate programs; cluster analysis was performed using the mge-cluster program, and phylogenetic analysis was performed using the Parsnp program. Results. 296 plasmid sequences isolated from 23 countries from clinical isolates of K.pneumoniae between 2006 and 2021 with a peak in 2019 were analyzed, with more than half of the plasmids coming from China. More than 30 sequence types were identified, among which ST11 and ST23 were predominant. Replicon genes of the IncFIB group were identified in almost all plasmids studied. The pre dominant type of aerobactin in the studied sequences was the first type (iuc1); sequences with iuc3 and iuc5 were also identified. Salmochelin synthesis genes were identified in only 37.1% of sequences; the yersiniabactin cluster was identified in two plasmids from China. 32.1% of plasmids carried resistance genes, of which 7.4% carried extended-spectrum beta-lactase genes and 5% contained carbapenemase genes. Nine clusters of sequences were obtained; almost all plasmids from Russia were assigned to one cluster and were NDM-positive. Together with plasmids from other European countries (Great Britain, Norway, Czech Republic), they formed a separate branch on the phylogenetic tree. Conclusion. Virulent plasmids carrying the aerobactin synthesis gene cluster are distributed globaly, and almost a third of them also carry antibiotic resistance genes.
The Renaissance of Spiramycin in Clinical Practice
Authors: Yakovlev S. V. , Suvorova М. Р.
Published: December 2023

Spiramycin is a natural 16-membered macrolide antibiotic that has been used in clinical practice for about 70 years. Despite long-term use, spiramycin retains its position in clinical practice; the resistance of the main respiratory and urogenital pathogens is lower to spiramycin than to 14- and 15-membered macrolides. The interest in spiramycin is due to the fact that its physico-chemical and pharmacokinetic properties are similar to the last semi-synthetic macrolides, and it lacks the disadvantages of erythromycin. Special biological properties of spiramycin explain its consistently high clinical efficacy that has lasted for 70 years of clinical use in various infections. It is necessary to emphasize the uniqueness of spiramycin as an antibiotic with not only the direct effect on microbes, but also non-antibiotic properties. This allowed the experts at the time to declare the «paradox» of spiramycin — the presence of a higher real clinical efficacy than expected according to in vitro studies. Such properties of spiramycin include pro-antibiotic and post-antibiotic effects, immunomodulatory effect, as well as high intracellular and extracellular concentrations of the antibiotic. The review discusses antimicrobial, pharmacokinetic, and pharmacodynamic characteristics of spiramycin and its place in the treatment of various infections — respiratory, ENT, urogenital, gynecological, and dental.
First record of the tribe Oecleini in Australia (Hemiptera: Auchenorrhyncha: Fulgoromorpha: Cixiidae) with the description of a new genus and species
Authors: Holzinger Werner E. , Löcker Birgit
Published: December 2023

A new genus and species, Apollo maculiceps gen. & sp. nov., in the planthopper family Cixiidae is described from south Western Australia. It can be distinguished from all other Australian Cixiidae by the presence of a denticle on the distal part of the fore coxa, a character that is shared with some other Oecleini genera. Large numbers of Apollo maculiceps gen. & sp. nov. were observed feeding on a native Australian cycad Macrozamia riedlei (family Zamiaceae). This is the first record of the economically important tribe Oecleini from Australia. A revised key to the tribes of the Australian Cixiidae is presented.
Listen up, kids! How mind wandering affects immediate and delayed memory in children
Authors: Cherry Jessica , McCormack Teresa , Graham Agnieszka J.
Published: December 2023

Mind wandering occurs when attention becomes disengaged from the here-and-now and directed toward internally generated thoughts; this is often associated with poorer performance on educationally significant tasks. In this study, 8- to 9-year-old children (N = 60) listened to audio stories embedded with intermittent thought probes that were used to determine if participants’ thoughts were on or off task. The key objective was to explore the impact of probe-caught mind wandering on both immediate and delayed memory retention. Children reported being off task approximately 24% of the time. Most inattention episodes were classified as task-unrelated thoughts (i.e., ‘pure’ instances of mind wandering, 9%) or attentional failures due to distractions (9%). Higher frequency of mind wandering was strongly associated with poorer memory recall, and task-unrelated thoughts strongly predicted how well children could recall components of the audio story both immediately after the task and after a 1-week delay. This study is the first to demonstrate the impact of mind wandering on delayed memory retention in children. Results suggest that exploring mind wandering in the foundational years of schooling could provide the necessary empirical foundation for the development of practical interventions geared toward detecting and refocusing lapses of attention in educational contexts.

El derecho de huelga a tiempo parcial limitado por razones sanitarias
Authors: Ahijado Novoa Pablo
Published: December 2023

El derecho de huelga, aunque está reconocido constitucionalmente, no está demasiado desarrollado en España, lo que desemboca en situaciones en las que el Tribunal Constitucional tiene que aclarar si se está haciendo un uso adecuado y motivado de los servicios mínimos, o si nos encontramos ante una limitación excesiva de este derecho. En la sentencia 2/2022 del Tribunal Constitucional, se resuelve el recurso de amparo sobre unos servicios mínimos que involucraron a la totalidad de los trabajadores de un área de la empresa, con objeto de mantener el nivel habitual de servicios bajo el pretexto de preservar el derecho a la salud de los ciudadanos.
Este caso decide favorablemente para el sindicato que demandaba amparo, al considerar vulnerado el derecho a huelga de los trabajadores de la empresa. Así, entran en debate diversos conceptos jurídicos como la proporcionalidad de los servicios mínimos, la existencia de un bien constitucional que para protegerse necesite limitar el propio derecho de huelga, la trascendencia constitucional de los hechos como elemento formal en el proceso del recurso de amparo, o las huelgas convocadas en tiempo parcial (que no ocupan toda la jornada laboral del trabajador).

El objetivo de la investigación fue conocer la actividad patológica producida por las esporas juveniles de Kudoa peruvianus, que al ingresar por los vasos sanguíneos, tejidos hematopoyéticos, tejido neuronal, ganglionar generan daño tanto como esporas monospóricas, dispóricas o polispóricas; o formando plasmodios. Se formaron 5 grupos de un total de 76 merluzas; se analizaron las microfotografías a través del microscopio, en el laboratorio de la Universidad Nacional La Molina (UNALM). En los plasmodios y los vasos sanguíneos, los trofozoitos fueron alargados y con un extremo agudo; mientras que en los tejidos hematopoyéticos mostraron formas únicamente alargadas; y en los tejidos neuronales y ganglionares se mostraron de forma redonda y pequeña . Las esporas que se encontraron en los quistes alargados fueron lobulares y con presencia de glóbulos blancos nucleados. En el quiste redondo también se encontraron células nucleadas redondas estrechamente rodeadas por tejido conectivo y colágeno. Estas células  probablemente corresponden a  esporoblastos, que  luego dan  lugar  a  células valvogénicas, capsulogénicas y esporoplásmicas. La presencia de estas esporas jóvenes siempre presenta una infección grave y generan la formación de tejido conectivo y necrosis a nivel del tejido muscular.

Published: December 2023

Raising disaster awareness for student teachers has become a necessity nowadays, especially in Indonesia which is geographically located in the world's ring of fire. It is hoped that the physics practicum-based landslide learning model will be able to raise disaster awareness among prospective teachers. By using a landslide case study, this research seeks to create a disaster learning resource model that is student-oriented, including lesson plans, LKPD, syllabus, and disaster awareness evaluation. The 4D model research design—Define, Design, Develop, and Disseminate—is the research methodology used in this research. Analysis of learning objectives, disaster awareness, and disasters is completed in the Define step. Learning tools are created during the Design stage. Product development, product expert validation, product revision, and testing of methods for evaluating student instructors' knowledge of disasters are all carried out in the development stage; Product distribution has not been completed at the disseminate stage. The trial was carried out among a sample of fifteen prospective teachers from the Physics Education Study Program, FKIP, Mataram University. The expert validator test of the disaster (landslide) learning model learning tool based on practical physics gave valid results. The results of the validity and reliability test of the disaster awareness evaluation instrument are valid and reliable. These results support the idea that disaster awareness assessment instruments and learning resources for prospective teachers can be used in the classroom.

Published: December 2023

The process of utilizing electromagnetic radiation from the radiometric values (Near-Infrared/NIR) and RED in the Normalized Difference Vegetation Index (NDVI) on Sentinel-2 imagery involves measuring light reflection at specific wavelengths reflected by vegetation. NDVI is computed by taking the difference between NIR and RED reflectance, then dividing it by their sum. In-depth analysis of electromagnetic wave interaction and plant spectral characteristics, such as NIR light reflection in healthy leaves, enables mapping vegetation health levels. The research aims to process image data and create a model visualizing vegetation health in the Sentinel-2 research area. Across the total area of 601,971,281.26 m2, 30.37% is healthy vegetation, 12.52% is moderate, and 53.33% is low or unhealthy. The least healthy area has an NDVI of -0.2006, while the healthiest area has a value of 0.6043.

Doğal diller, o kodla iletişim kuran toplumların kültürel niteliklerini ortaya koyabilen en temel dizge olarak kabul edilmektedir. Dil ve kültür, etkileşimli bir alanda gelişmekte ve kültür, dili içerip dönüştürürken dil de kültürün yapılanması ve somutlaşmasına olanak sağlamaktadır. Bu bağlamda dilde bazı sözcüklerin, kültür aktarımında belirgin ve öncül bir rol oynadığı gözlemlenmektedir. Kültürel anahtar sözcükler olarak adlandırılan bu tür yapılar bir başka dile bütün içlemsel ve buna bağlı olarak uzanımsal nitelikleriyle çevrilememektedir. Bu setler üretim açısından farklı uzlaşı, gelenek ve ritüeller doğrultusunda şekillenmekte; toplumların soyut ve somut düzlemlerdeki kavramlaştırmalarını daha yapılandırılmış bir biçimde ortaya koyabilmektedir. Bu çalışmada Türkçenin anlam evrenine özgü olan ve farklı bir dile kültürel uzanımlarıyla birlikte çevrilmeye izin vermeyen düğün sözcüğünün eşdizimlilik ve anlam tercihi görünümleri araştırma konusu yapılmıştır. Bu kapsamda toplumsal bağlamda önemli bir geçiş töreni olan düğün kavramı doğal dilsel veriler ışığında incelenmiş ve Türk toplumunun belleğinde söz konusu etkinliğin nasıl yapılandırıldığı ortaya konmuştur. Araştırma betimsel modelde tasarlanmış ve elde edilen veriler içerik analizi kapsamında temalar ve kategoriler oluşturularak çözümlenmiştir. Düğün kavramının kültürel katmanlar temelli şekillenmesi, kavramlaştırma sürecinde kent/taşra ayrımının belirginleşmesi ve senaryoların da buna göre oluşması, söz konusu düğüm sözcüğün YER, TÜR, ZAMAN gibi 11 farklı alt ulam çevresinde kurgulanması elde edilen önemli sonuçlar arasındadır.
Rus Ressam Vrubel ve Rus Yazar Lermontov’un Sanatında Şeytan İmgesi

Yabancı dil eğitiminde birçok alanı inceleriz. Herhangi bir dili öğrenmek ve doğru kullanabilmek için sadece dilbilgisini öğrenmek yeterli değildir. Aynı zamanda o dilin kültürünü, edebiyatını, tarihini, hatta politikasını de incelemek gerekir. Bu çalışmada Rus kültürü için önemli bir yere sahip olan ancak Türkiye’de sanat alanı dışında belki de çok tanınmayan, Rus dili ve edebiyatı çalışmalarında ise henüz ele alınmamış bir kişilik olan Rus ressam Mihail Vrubel’in yaşamı, sanat anlayışı, felsefesi ve özgünlüğü ele alınmaktadır. Bununla amaç, yazarı ve sanatını tanıtmak, Rus insanını ve estetik zevklerini ressam üzerinden anlamaya çalışmak ve bir sanat dalı olan resim sanatının diğer bir başka sanat dalı olan edebiyattan nasıl etkilediğini ortaya koymaktır. Bu etkileşimin nasıl gerçekleştiğini ortaya koyabilmek adına da Vrubel’in şeytanı konu alan resim üçlemesi ile Lermontov’un “Şeytan” poemasındaki şeytan imgesi incelenmektedir. Dönem özelliklerinin ele alınarak sunulduğu çalışmada Vrubel’i daha iyi tanıtabilmek adına önce kısa bir biyografisi verilmekte ardından sanat yaşamını icra ettiği dönem özelliklerine değinilmektedir. Son olarak Lermontov ve Vurbel’in şeytan imgeleri karşılaştırmalı olarak genel hatlarıyla analiz edilmektedir. Her iki dehanın çalışmaları demonoloji konusunda irdelenmeye değer eserler olmakla birlikte eserleri, din veya daha gelenekselleşmiş düşüncelerin ötesine geçerek herkesin içindeki şeytanı kendine göre yorumlayabileceğini göstermektedir.

Elektronik aletlerle oynanan oyunlar beraberinde bağımlılığa yol açtığı için gergin stresli bir hayat sürülmesine neden olmaya başlamıştır. Bu çalışmada il spor merkezlerindeki öğrencilerin dijital oyun bağımlılıklarının incelenmesi amaçlanmıştır. Bu araştırma tarama modelli nicel araştırma yöntemli bir çalışmadır. Araştırmanın örneklemini Yozgat’taki spor merkezlerinde kolay ulaşılabilir durum örneklemesi yöntemi ile seçilen 181 sporcu oluşturmaktadır. Kişisel bilgilerini içeren form ile öğrencilerin dijital oyun bağımlılığını incelemek amacıyla Hazar ve Hazar (2017)’ın geliştirdiği “Çocuklar İçin Dijital Oyun Bağımlılığı Ölçeği” (ÇİDOBÖ) kullanılmıştır. Veriler google form aracılığı ile elde edilmiştir. Verilerin dağılımında Kolmogorov-Smirnov testi kullanılmış ve normal bir dağılım gösterdiği tespit edilmiştir. Verilerin analizinde One-Way ANOVA ve t- Testi kullanılmıştır. Cinsiyet ve spor türü değişkeni ile ölçeğin alt boyutlarında anlamlı farklılık tespit edilememiştir. Yaş değişkeni ile yoksunluğun psikolojik-fizyolojik yansıması ile oyuna dalma alt boyutunda, spor yılı değişkeni ile oyun süresinde tolerans gelişimi ile oyuna yüklenen değer alt boyutunda, oyun oynama süresi değişkeni ile ölçeğin tüm alt boyutları arasında anlamlı farklılık tespit edilmiştir. Araştırmada, dijital oyun bağımlılığının cinsiyet ve spor türü değişkenlerinden etkilenmediği, yaş, spor yılı, spor branşı ve oyun oynama süreleri değişkenlerinden etkilendiği sonucuna ulaşılmıştır.

İmplantasyon, gebelikte embriyo ile endometriyum epiteli arasında sürekli olarak temasın sağlanmasıdır. Endometriyumun implantasyona açık olduğu dönem, implantasyon penceresi olarak tanımlanmaktadır. İmplantasyon penceresi döneminde birçok molekül etkili olmaktadır. Hormonlar, sitokinler, kemokinler, adezyon molekülleri, büyüme faktörleri ve çeşitli genlerin etkisi ile bu süreç koordineli bir şekilde yönetilmektedir. İmplantasyon bu faktörlerin etkisi ile sırasıyla apozisyon, adezyon ve invazyon aşamalarından oluşmaktadır. Bu aşamalar sadece implantasyon penceresinde gerçekleşebilmektedir.

Başarılı bir implantasyon olmadan, embriyonun gebeliğin diğer dönemlerine geçişi mümkün değildir ve gebelik erken embriyonik ölümle sonuçlanmaktadır. Bu açıdan multifaktöriyel birçok molekülün koordinasyonuyla meydana gelen implantasyonda, implantasyon penceresi zaman aralığı gebelik sürecindeki kritik noktalardan biridir. Bu derlemede sağlıklı bir gebeliğin oluşabilmesi için gerekli olan başarılı bir implantasyon ve implantasyon penceresi hakkında bilgi verilmeye çalışılmıştır. Fakat bilinmelidir ki, implantasyon mekanizmaları tüm bilinenlere rağmen hala tam olarak aydınlatılamamıştır.

Published: December 2023

Türk aile sistemi içerisinde çocuk sahibi olmak oldukça önemlidir. Kadim Türk topluluklarından günümüze çocuk, ailenin birliğini ve soyun devamlılığını sağlayan yegâne unsur olarak görülmüştür. Türk kültüründe, kadının gebe olduğunun kanaatine vardığı ilk andan itibaren başta anne adayı olmak üzere aile bireyleri tarafından doğacak çocuğun cinsiyeti merak edilmiştir. Bu merak halk inanışlarında doğacak çocuğun cinsiyetinin tahmin edilmesine yönelik pratiklerin ortaya çıkmasını sağlamıştır. Deneme, yanılma ve gözlem sonucu elde edilen cinsiyet tahminine yönelik halk bilgileri sözlü kültür ortamında canlılığını korumuştur. Bu çalışmada, Türk kültüründe doğacak çocuğun cinsiyetinin tahmin edilmesine yönelik inanışlar ele alınmıştır. Çalışmada, Anadolu Türk halk inanışları başta olmak üzere Türk toplulukları üzerine yapılan inanç kökenli kültürel dokümanlar incelenmiş ve doğacak çocuğun cinsiyetinin tahmin edilmesine yönelik uygulamalar tasnif edilerek yorumlanmıştır. Türk kültüründe cinsiyet tahminine yönelik uygulamaların hangi inanışlar ekseninde ortaya çıktığı incelenmiş ve derinlemesine kültür analizi yapılmıştır.
