Published: December 2024

In the Ejigbo Local Government Area of Osun State, a Nigerian derived savanna zone, a study was carried out to examine certain phenotypic characteristics of West African dwarf goats. Three hundred ninety-nine (399) West African dwarf goats were sampled in order to determine their live weight and body measurements. Analysis was done on data pertaining to 194 bucks and 205 does. These were categorised into six age groups (milk teeth, 2-teeth, 4-teeth, 6-teeth, 8-teeth, and worn teeth) and recorded by sex. In order to characterise the goat breeds in the trial region, the goal was to give comprehensive information on linear body measurements. For both sexes, body measurement values rose significantly (P<0.05) with age. For bucks, the mean body weight was 5.32 ± 0.15 to 29.63 ± 1.88 kg, while for does, it was 5.75 ± 0.13 to 30.29 ± 1.22 kg physical weight and other physical characteristics were discovered to differ by sex. In animal genetic resources, body weight and linear body measurements are economically significant features, particularly for small ruminants like goats during selection and to give precise weight determination in remote locations without a scale. Linear measurements and body weight are important traits in meat animals. Quantitative measurements of the ideal body size and form are obtained from the analysis of body measuring data, which enables the computation of genetic parameters for these features and their incorporation into breeding plans. Given the high correlation and regression coefficients of linear body measurements in West African dwarf goats, the results of this study suggest that live weight can be predicted using certain body measurements. Lastly, there was a significant and favourable correlation between body weight and body measurements. Given this, it might be applied as a criterion for selection.

Mutator Circuit for Memcapacitor Emulator Using Operational Transconductance Amplifiers
Authors: Konal Mustafa , Kacar Fırat
Published: December 2024

In recent years, interest in memelements, including memcapacitors, has increased significantly following the realisation of memristors. This paper presents the design and implementation of a memcapacitor circuit based on operational transconductance amplifiers (OTAs). The proposed design is structured as a mutator circuit, where the second stage functions as a memristor, ultimately transforming the circuit into a memcapacitor emulator. The emulator features electronic tunability, which allows the charge value of the memcapacitor to be adjusted by modifying the capacitor in the mutator stage. The charge value of the memcapacitor can also be adjusted by varying the transconductance gm value of the OTA active element. Additionally, the operational frequency of the memcapacitor can be varied by altering the capacitor in the second stage. An adaptive learning circuit based on the memcapacitor emulator is demonstrated to validate the circuit performance. The time response obtained when a sine signal is applied to the memcapacitor circuit, the input voltage-charge relationship, and the charge-time response obtained when a square wave is used to demonstrate its memory characteristics are provided. All simulations were conducted using LTSpice with Taiwan Semiconductor Manufacturing Company (TSMC) 0.18 μm complementary metal oxide semiconductor (CMOS) process parameters. The results corroborate the effectiveness of the circuit, highlighting its potential for advanced electronic applications.

The early diagnosis of DR using computer-aided automated tools is possible due to tremendous advancements in machine and deep learning models in the last decade. Devising and implementing innovative deep learning models for retinal structural analysis is crucial to the early diagnosis of DR and other eye diseases. In this work, we have developed a new approach, which involves the development of a lightweight convolutional neural network (CNN)-based model for segmentation of retinal vessels and a mobile application for DR grading. This paper covers the development process of an Android application that leverages the power of CNN-based deep learning model to detect DR regardless of its stage. To achieve this, two models have been created and compared, the best one having an accuracy of 96.72 %. An Android application has then been developed, that makes calls to this model and then displays the results on screen with a simple-to-understand interface developed using the Kivy framework.

Background: Developed nations have well-structured health systems where cervical cancer (CC) screening is routine, accompanied by effective treatment and follow-up for positive cases. In contrast, many developing countries, particularly in sub-Saharan Africa, lack specialized health infrastructure, treatment options, equipment, and qualified healthcare professionals. Screening initiatives are often limited in scope and lack sustained follow-up. As a result, approximately 90% of CC cases in these regions are diagnosed at advanced stages, exacerbated by socioeconomic challenges.

Aim: This study aims to explore the socioeconomic and cultural factors contributing to cervical cancer risk among women in Doukoula, Far North Region of Cameroon.

Method: A community-based cross-sectional study was conducted from November 3-9, 2021, among women aged 16 to 80 years in Doukoula and surrounding areas. Data collection involved face-to-face interviews using a structured questionnaire with 26 questions covering respondent identification, demographics, and cervical cancer screening (CCS) information. Data were entered into a Microsoft Office Excel spreadsheet, checked for consistency, and analyzed using CDC Epi Info version 7.2.5.0. Associations between respondent characteristics and CCS uptake were assessed using the Pearson Chi-square (χ²) test (significance level: 0.05).

Results: Socioeconomic and cultural factors, including area of residence, age at first sexual activity, number of sexual partners, lack of information, education level, poverty, illiteracy, poor communication, cultural beliefs, and awareness gaps, were identified as barriers to effective cervical cancer prevention and control.

Conclusion: This study highlights the complex socioeconomic and cultural vulnerabilities contributing to cervical cancer risk among women in Doukoula. Addressing these factors is crucial for improving prevention, early detection, and treatment outcomes.

GELİŞMEKTE OLAN ÜLKELERDE BORSA BÜYÜKLÜĞÜNÜN FİRMALARIN SERMAYE YAPISI ÜZERİNE ETKİSİ
Authors: Yılmaz Muhammed
Published: December 2024

Kurumsal finans teorilerinin gelişimiyle birlikte sermaye yapısı ile ilgili literatürde birçok çalışma yapılmıştır. Firmaların varlık ediniminde, nasıl bir sermaye yapısına sahip olması gerektiği ve finansman çeşitliliğinin nasıl olması gerektiği finansal kararların en başında gelen konulardan olmuştur. Sermaye piyasasının gelişmişliğinin bir göstergesi olan borsa büyüklüğü, bir ülkedeki dolaşımdaki pay senetlerinin toplam değerini ifade eder. Bu çalışmanın amacı, finansman ihtiyacının yüksek olduğu gelişmekte olan ülkelerin borsa büyüklüğünün firmaların sermaye yapısı üzerine etkisini araştırmaktır. Araştırmada panel veri regresyon yöntemi kullanılmıştır. Veri seti, 1996-2019 yılları arasında, 10218 firmadan elde edilen 96946 gözlem sayısından oluşmaktadır. Elde edilen bulgulara göre borsa büyüklüğünün, toplam borç oranı ve uzun vadeli borç oranı üzerine negatif ve anlamlı etkisi, kısa vadeli borç oranı üzerine ise pozitif anlamlı etkisi tespit edilmiştir. Ayrıca firmaların kârlılık, maddilik, nakit, PD/DD, büyüklük, Ar-Ge harcamaları ve firma riski değişkenleri kontrol değişkeni olarak modelde kullanılmıştır. Gelişmekte olan ülkelerde sermaye piyasasının gelişimi, pay piyasasının büyümesine katkı sağlamaktadır. Bu bağlamda, borsa büyüklüğü, firmaların öz kaynak kullanımını destekleyen önemli bir faktör olarak öne çıkmaktadır. Bu nedenle, borsa büyüklüğü ile firmaların sermaye yapısı arasında uzun vadede negatif bir ilişki olduğu gözlemlenmiştir. Bu çalışma, elde edilen bulgular doğrultusunda literatüre özgün ve kapsamlı bir katkı sunmaktadır.
Cumhuriyetten Günümüze Türkiye İç Borçlarının Seyri

Gelişmiş ve gelişmekte olan her ekonomi yeni kaynaklara ihtiyaç duymaktadır. Ekonominin başındaki hükümetler de kaynak ihtiyaçlarını ulaşılması çok daha kolay olan borçlanmayla karşılamayı tercih etmektedirler. Ancak; dikkatli bir şekilde kullanılmayan ve yönetilemeyen borçlanmalar bir bağımlılığa dönüşmekte ve içinden çıkılamaz bir kısır döngü ortaya çıkarmaktadır. Nitekim, Osmanlı İmparatorluğu’nun sonunu getiren ekonomik sorunların başında da borçlanma gelmektedir. Osmanlı’nın kötü tecrübesinden ders almış olsa da Türkiye, Atatürk sonrasındaki dönemlerde borçlanmanın cazibesine kapılmış ve bunun acılarını çekmiştir. Borçların yarattığı krizler sonrasında önlemler alınmış, kemer sıkma politikaları uygulanmış, ancak yapılan bu düzenlemeler bir sonraki borç krizini engelleyememiştir. İçinde bulunduğumuz 2020’li yıllarda da durum pek de farklı değildir. Bu çalışmada Türkiye Cumhuriyeti’nin kurulduğu günden bugüne iç borçlanması ve borç stokunun seyri, alt dönemler itibariyle incelenmektedir.
Türkiye İş Gücü Piyasasının 100 Yıllık Dönüşümü
Authors: Tosun Oktay
Published: December 2024

Bu çalışma, Türkiye Cumhuriyet’inin kuruluşundan itibaren emek ve iş gücü piyasalarındaki yapısal dönüşümlerini tarihsel, ekonomik ve teknolojik bağlamda incelemektedir. Çalışma, Türkiye’nin yüz yıllık iş gücü gelişimini dört ana döneme ayırarak ele almaktadır: Erken Cumhuriyet Dönemi, sanayileşme ve şehirleşme (1950-1980), ekonomik-sosyal değişimler (1980-2000) ve küreselleşme ile teknolojik değişim (2000-2023). Erken Cumhuriyet döneminde, tarıma dayalı bir ekonomiden sanayiye geçiş hedeflenmiş, fakat savaşların etkisiyle iş gücü piyasası kadın ve çocuk emeğine dayanmıştır. Bu dönemde işçi hakları, sosyal güvenlik ve çalışma koşullarını düzenleyen ilk politikalar hayata geçirilmiştir. 1950-1980 arası dönemde sanayileşme ve kentleşme hızlanmış, iç göçler artmış, ancak ekonomik krizler ve yetersiz politikalar nedeniyle kalkınma süreci sekteye uğramıştır. 1980 sonrası dönemde, neo-liberal politikalar ve küreselleşme etkisiyle esnek iş gücü piyasaları ve dışa açık ekonomi yapısı gelişmiştir. Ancak bu süreçte işsizliğin artması ve iş gücü piyasasındaki eşitsizlikler önemli sorunlar olarak varlığını sürdürmüştür. 2000’li yıllarda teknolojik gelişmeler, iş gücü talebini nitelikli becerilere yöneltmiş, buna karşın kayıt dışı sektör ve istihdam yetersizliği gibi yapısal sorunlar devam etmiştir. Bölüm, Türkiye’nin iş gücü piyasalarının sürdürülebilirliği için eğitim, teknolojik uyum ve istihdam politikalarının entegrasyonunun önemine dikkat çekmektedir.
