Study Design: The number of patients that were evaluated from January 2015 to September 2019 were 417. At the end of this study period, 375 patients were considered for this prospective evaluation. The patients with an ultrasound diagnosis of unilateral and unilocular ovarian cysts with regular septa ≥ 10 cm in diameter at menopause were enrolled in this study. During the follow-ups, the patients who developed irregular or thick septa, papillary formation or solid areas, exhibited any suspicious sign of malignancy in magnetic resonance imaging (MRI) results or displayed an augmentation in CA-125 levels were excluded from the study. In this study cancer antigen-125 (CA-125) values > 65 IU/mL were considered abnormal. The patients who met these criteria were followed with periodical ultrasounds and yearly MRI. Results: The 42 patients who were excluded from the study had significant morphological changes. These patients were showing an increase in CA-125 levels along with abnormal MRI findings during the follow-ups and in addition, they had surgical removal of cysts. All the significant morphological changes were detected by transvaginal ultrasounds. Postoperative histopathological diagnosis of these ovarian cysts revealed no abnormality. From 375 patient's cysts samples one hundred and twenty-five (33.3%) cysts had significantly decrease in size, one hundred and eleven (29.6%) of the cysts had spontaneous resolution and one hundred thirty-nine (37%) cysts persistently remained unchanged during the follow up period. The diameter of the cysts ranged from 10.4 to 18.4 cm. The cysts were categorized into three groups corresponding to a range of diameters i.e., 10-12.9 cm (62%), 13-15.9 cm (24.1%) and ≥ 16 cm (13.8%) respectively. The patients who showed spontaneous resolution were discontinued with the follow-ups while the rest of the patients were continued with their regular follow up examinations. Conclusion: The cysts should be monitored conservatively as long as possible before proceeding to a surgical treatment regardless of the size of the unilateral and unilocular ovarian cysts at postmenopausal period with limited oncogenic potential and without significant morphological changes. © 2021 The Authors.Article Citation - WoS: 7Citation - Scopus: 13An Expert System for the Diagnosis of Sexually Transmitted Diseases - Esstd(Ios Press, 2017) Thompson, Temitope; Sowunmi, Olaperi; Misra, Sanjay; Fernandez-Sanz, Luis; Crawford, Broderick; Soto, RicardoOver 93 million people get ill with sexually transmitted diseases in sub-Saharan Africa. However, research has shown that people with sexually transmitted diseases find it difficult to share their problem with a physician due to societal discrimination in Africa. Due to this problem, we have implemented a medical expert system for diagnosing sexually transmitted diseases (ESSTD) that maintains the anonymity of the individuals. The patients diagnose themselves by answering questions provided by the system. This paper presents the design and development of the system. Forward chaining rules were used to implement the knowledge base and the system is easily accessible on mobile platforms. The Java Expert System Shell was used for its inference engine and the system was validated by domain experts. It is useful because it helps to maintain anonymity for patients with STD.Article Citation - WoS: 20Citation - Scopus: 28Modelling and Optimisation of an 8 X 8 Heavy Duty Vehicle's Hydro-Pneumatic Suspension System(inderscience Enterprises Ltd, 2016) Kucuk, Kahraman; Yurt, Hunkar Kemal; Arikan, Kutluk Bilge; Mrek, Huseyin; Imrek, HüseyinIn this paper, modelling of the hydro-pneumatic suspension (HPS) system of a heavy duty vehicle that has all-wheel steering and driving capability is studied. The prototype vehicle of concern is a mobile telescopic crane. The spring and damper effects of the HPS, which is used generally in heavy commercial vehicles and in military vehicles, have been modelled separately. First, HPS dynamics is studied on 1/8 vehicle model and then vehicle dynamics is examined on the MSC ADAMS/Car model. HPS of the prototype vehicle is assessed by some objective functions. In addition, simulation-based optimisation is performed using a 1/8 vehicle model. Various designs are obtained and their performances are compared with that of the prototype vehicle's HPS by the ADAMS/Car model simulations. Modelling and optimisation studies reveal a sound background to improve the prototype vehicle and to design active HPS system.Article Investigating Student Churn Among Business Schools in Higher Education(Tuba-turkish Acad Sciences, 2023) Yalcin, Aybueke; Uner, M. Mithat; Karatepe, Osman M.; Aboramadan, MohammedThe purpose of our paper is to examine what the reasons for student churn are and why students begin their educational careers in a school of business and then leave and register at another university. Following a qualitative methodology, semi-structured interviews were conducted with 31 students (11 females, 20 males; mean age: 21.12; range: 19 to 25 years) who had switched from one business school to another in Ankara, the capital city of T & uuml;rkiye, and QSR NVivo 12 for Windows was used to analyze the qualitative data. The findings reveal that the main reason of student churn is associated with obstacles regarding the use of English as the medium of instruction. This is followed by dissatisfaction with the school or the department. The reasons for students preferring another university are also related to having friends at the university chosen, proximity to home, referrals, and family members. The study provides important insights to university administrators pertaining to the reasons associated with student churn in higher education. When the results are examined by university type, it is seen that the dissatisfaction with the university or department was the primary reason for the students who left the state universities, while the foreign language problem was the reason for the students who left the foundation universities. Considering the findings of the study, the university administration should concentrate on how to improve students' foreign language skills, invest more in research and innovation, and increase social activities to improve communication among students.Article Citation - WoS: 24Citation - Scopus: 27Global Asymptotic Stability of Cellular Neural Networks With Unequal Delays Lmi Approach(Iee-inst Elec Eng, 2004) Singh, VA criterion for the global asymptotic stability and uniqueness of the equilibrium point of cellular neural networks with unequal delays is presented. The criterion is computationally efficient, since it is in the form of linear matrix inequality (LMI).Article Citation - WoS: 3Citation - Scopus: 5Reliability-Based Evaluation of Scouring Around Dual Bridge Piers(Croatian Soc Civil Engineers-hsgi, 2019) Yilmaz, Meric; Calamak, Melih; Yanmaz, A. MelihThe causes of uncertainty involved in temporal variation of the depth of cavern formation due to clear water scouring at dual piers with tandem arrangement are identified in this study. In an example, the probability of failure induced by scouring around dual piers is estimated for various pier spacing using probabilistic analysis. The effects of changes in the coefficient of variation of probabilistic scouring variables and probability distributions on the probability of the loss of stability, are also investigated. It was established that the effects of variations in the coefficient of variation on the probability of the loss of stability are more significant compared to that on the probability distributions of the scour depth.Article Citation - WoS: 3White Box Test Tools: a Comparative View(Union Scientists Bulgaria, 2019) Atesogullari, Dilara; Mishra, AlokThere are multiple software testing techniques in the literature.

The Eu and China in The Western Balkans(Turkish Policy Quarterly, 2024) Yilmaz, GozdeThe Western Balkans have been transformed into authoritarian regimes in the last decade, despite the EUs' engagement with the region through its enlargement policy. However, prioritizing stability over democracy, the EU lost its chance to transform the Western Balkan countries into democratic entities. In the end, the EU opened a way in for the external actors to the Western Balkan countries and China has entered the scene by increasing engagement with the region. The leaders of the authoritarian regimes in the Western Balkans adopted a pragmatic approach in their relations with China. They used the Chinese card to proceed with their relations with the EU and to gather financial means to legitimize and consolidate their regimes.Article Citation - Scopus: 1Effects of Carbon Dioxide Pneumoperitoneum on Renal Function in Obstructive Jaundice: an Experimental Study in a Rat Model(Asoc Regional Dialisis Trasplantes Renales, 2023) Gulen, Merter; Sare, Mustafa; Kozan, Ramazan; Yuksel, Seher; Deger, Serpil Muge; Senes, Mehmet; Cayci, Ayse BanuIntroduction: Both pneumoperitoneum (PNP) and obstructive jaundice (OJ) are known to lead to acute kidney injury (AKI) potentially, but the combined effect has not been investigated. Aim: This study aimed to investigate the effects of PNP on renal functions in a rat model of OJ. Methods: We divided forty-eight rats into eight groups of six rats. Group 1 was the control (sham-operated) group; Groups 2, 3, and 4 were induced 5, 10, and 15 mmHg of CO2 PNP, respectively (Groups 1-4: "non-OJ Groups"); Group 5 was the OJ group; and Groups 6, 7 and 8 were OJ groups that were induced with 5, 10, and 15 mmHg CO2 PNP was respectively (Groups 5-8: "OJ Groups"). The common bile duct was ligated and divided into OJ Groups. After 48 hours, a 5-10-15 mmHg PNP was induced by mini-laparotomy with a Veress needle in Groups 6, 7, and 8, maintained for 60 minutes. Results: There were no statistically significant differences between groups regarding blood urea Nitrogen and Creatinin levels (p> 0.05). Neutrophil gelatinase-associated lipocalin (NGAL) values were significantly higher in OJ Groups than in non-OJ Groups (p< 0.05). Serum Cystatin-C values were significantly higher in OJ Groups with 10 and 15 mmHg PNP than in nonOJ Groups (p< 0.05). Conclusion: In the early stage of AKI, NGAL and Cystatin-C levels might be higher, while standard renal function tests were normal. Our findings highlight the apparent unfavorable effect of OJ with PNP on renal functions and early recognition of AKI with the measurement of NGAL and Cystatin-C in these conditions.
