Comparison and accuracy assessment of unmanned aerial vehicle and terrestrial measurement in base map production
(Elsevier B.V., 2025) Yıldız, Veysel; Yaman, Aydan
In the present era, unmanned aerial vehicles (UAVs) have become a prevalent tool for data and map production in the domain of remote sensing and photogrammetry, driven by advancements in technology. The production of base maps has become more straightforward, precise, economical, and time-efficient in recent years, largely due to the advent of UAVs and the subsequent development of new techniques. The base maps of the area were produced using two methods: Terrestrial measurement and UAV data. The squared mean errors were calculated and found to be my = ±1.49 cm, mx= ±1.58 cm and mz = ±2.52 cm for ground control points, my = ±1.54 cm, mx= ±1.65 cm and mz = ±2.55 cm for check points and my = ±2.41 cm, mx= ±2.66 cm and mz= ±3.47 cm for detail points. The results were found to fall within the specified limit values. It was therefore concluded that UAVs provide the anticipated accuracy for the production of base maps, which are required to be continually updated and form the basis for a range of projects and can be readily employed in this regard. This study demonstrates that base maps produced with UAV data meet the requisite scientific and academic standards, including accuracy and precision. Additionally, it illuminates the advantages of UAV data in base map production, particularly in terms of time, accuracy, and cost.
Exploring the relationship between learning climate in schools and agile leadership using multi-group path analysis: does “Willingness to work” have a mediating role
(Springer, 2025) Sözer Boz, Esra; Tabak, Hasan
The learning climate in schools is significantly influenced by relationships among teachers, students, and school administration. Despite its importance, relatively few studies have explored the relationship between learning climate and principal characteristics from teachers’ perspectives. This study aims to examine the mediating role of teachers’ willingness to work in the relationship between the learning climate in schools and agile leadership. The participants consist of 630 teachers from various educational levels, ranging from preschool to high school. Data were collected using the Agile Leadership Scale, the Learning Climate Scale, and an item assessing teachers’ willingness to work. Mediation analysis was employed to examine the impact of teachers’ willingness to work on the relationship between agile leadership and the learning climate in schools. The findings revealed that willingness to work serves as a mediator in the relationship between the learning climate in schools and agile leadership. Multi-group path analysis indicated that this mediation effect was significant among male teachers, whereas they were not observed among female teachers. The overall results demonstrate that the learning climate in schools is affected by the agile leadership of the principals, and the willingness to work of teachers partially mediated this relationship. These findings underscore the importance of agile leadership behaviors in fostering a conducive learning climate and suggest that supporting teachers’ professional and personal development can further enhance this environment.

(AVES, 2025) Ergin, Mustafa; Ergin, Gülencan Yumuşak; Kıvrakoğlu, Fatih; İbiş, Mehmet
There are studies with different results on improving effectiveness and patient comfort by increasing lumen distention through positioning during colonoscopy. In our study, we aimed to compare colonoscopy outcomes and post-procedural patient comfort in the left-lateral and right-lateral positions. Materials and Methods: A total of 231 patients who underwent screening colonoscopy were included. Patients were randomized to either the left-lateral or the right-lateral position. Patient age, sex, comorbidities, body mass index (BMI) values, times to reach the cecum, ileum intubation rates, total procedure times, and colonoscopy findings were compared. Pain and discomfort after the procedure were evaluated and compared with the visual analog scale (VAS) scores at 30 minutes, 6 hours, and 24 hours. Results: Colonoscopy was performed in the left-lateral position in 129 patients and in the right-lateral position in 102. The distributions of age, sex, comorbidities, and BMI values were similar in both groups. The time to reach the cecum and the total procedure time were similar in both groups. There were no significant differences in the findings detected by colonoscopy. There was no significant difference in the post-procedural VAS scores. Conclusion: This study failed to show a difference in colonoscopy outcomes and postprocedural discomfort between the left- and right lateral positions.
Evaluation of the necessity of simultaneous cholecystectomy in patients undergoing liver hydatid cyst surgery
(Elsevier B.V., 2025) Martlı, Hüseyin Fahri; Aydın, Arzu Hazal; Şahingöz, Eda; Duru, Derviş; Er, Sadettin; Turhan, Nesrin; Tez, Mesut
Liver hydatid cysts remain a significant public health issue in Turkey, the Middle East, East Asia, and Russia. Surgical treatments are often employed for certain stages of this disease. However, the necessity of simultaneous cholecystectomy during these procedures remains unclear. Treating symptoms related to subsequent cholelithiasis can become more challenging. This study investigates the necessity of simultaneous cholecystectomy by following patients who underwent hydatid cyst surgery with or without concurrent cholecystectomy. Materials and methods: Patients who underwent surgery for hydatid cysts between 2019 and 2024 at the General Surgery Clinic of Ankara Bilkent City Hospital were retrospectively reviewed. A total of 97 patients were included, with 56 (54.32 %) undergoing cholecystectomy along with hydatid cyst surgery (Group 1) and 41 (45.68 %) not undergoing cholecystectomy (Group 2). Preoperative clinical, laboratory, and radiological findings, as well as intraoperative data, morbidity, mortality, and postoperative symptoms, were analyzed. Results: Patients in Group 1 had longer hospital stays, higher blood loss, and significantly higher Clavien-Dindo complication scores. In the postoperative follow-up of Group 2, 8 patients (19.51 %) developed stones or sludge, and 1 patient (2.4 %) developed polyps. Four patients (9.75 %) presented to the emergency department with cholecystitis symptoms. A total of 5 patients (12.19 %), including 4 with symptomatic cholelithiasis (9.7 %) and 1 with gallbladder polyps (2.4 %), underwent elective cholecystectomy. Two (40 %) of these cholecystectomies were performed laparoscopically, while three (60 %) were converted to open cholecystectomy. Conclusion: Simultaneous cholecystectomy during liver hydatid cyst surgery may prevent difficulties associated with treating symptoms related to subsequent cholelithiasis.
Pan-immune inflammation value and systemic inflammatory index as a measure of systemic inflammation in patients with psoriasis: A retrospective study
(Lippincott Williams and Wilkins, 2025) Başar Kılıç, Şeyma; Erdal, Hüseyin
Psoriasis is a chronic immune-mediated disease characterized by systemic inflammation. In recent years, the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and pan-immune-inflammation value (PIV) were shown to be important indicators of inflammation. The aim of the present study is to investigate NLR, PLR, SII, SIRI, PIV together in patients with psoriasis. This retrospective case-control study encompassed seventy-one individuals diagnosed with psoriasis and seventy healthy controls who underwent evaluation at the Dermatology clinics of Aksaray University Training and Research Hospital from January 2022 to January 2023. Inflammatory process indicators such as NLR, PLR, SII, SIRI, PIV were computed for analysis. A notable discovery from our research was the indication of a direct relationship between SII and Psoriasis Area Severity Index (PASI) scores. A statistically significant difference was found between the 2 groups in terms of neutrophils, lymphocytes, monocytes, and platelets (P < .05). The area under the curve of the SII score for psoriasis was 0.611. The optimal cutoff value of SII to predict psoriasis activation was 442.7, with 55.7% sensitivity and 45.7% specificity (95% confidence interval 0.518-0.704, P = .024). A positive correlation was observed between SII, PIV and PASI (P = .004, r = 0.34; P = .006, r = 0.32 respectively).There was no statistically significant distinction observed in the PLR indices between the groups (P > .05). The present study investigation demonstrates the potential utility of SII, SIRI, and PIV in assessing psoriasis patients. Moreover, the findings suggest that SII and PIV could function as an autonomous prognostic marker for individuals diagnosed with psoriasis.
