    The Role of Post-Traumatic Stress Symptoms and Post Migration Life Difficulties for Future Aspirations of Iraqi and Syrian Asylum Seekers
    (Başkent Üniversitesi Sağlık Bilimleri Fakültesi, 2024-07-12) Yildiz, Aylin Demirli; Strohmeier, Dagmar
    The majority of asylum seekers experience some kind of traumatic events before or during their flight and their challenging experiences do not end after resettlement. Still, they need to envision and build their future life in the host country. Moreover, asylum seekers' future aspirations need to be differentiated from the satisfaction of essential needs. We (1) measured future aspirations (FA); (2) explored whether FA and post-migration life difficulties (PMLD) differ between asylum seekers with high and low levels of post-traumatic stress symptoms (PTSS); and (3) examined whether PTSS, PMLD, gender, age, and length of stay are associated with different types of FA. In total, 139 Iraqi and Syrian asylum seekers (55 female, 83 male) aged 18 to 67 years (M = 34.03, SD = 10.35) participated. A four-factor structure of FA was confirmed by confirmatory factor analysis (CFA). Participants with high levels of post-traumatic stress symptoms reported higher levels of PMLD and lower levels of FA related to their home country. FA related to the host country and FA related to occupation were predicted by lower levels of post-traumatic stress symptoms, while future aspirations related to the home country were predicted by higher levels of PMLD. Results indicate that asylum seekers who experienced more traumatic events before they migrated are more reluctant to return to these places in the future. Treating the psychological impairments of this highly vulnerable group and relaxing the manifold structural barriers are crucial to foster their construction of a future life.

    A Pilot Study on Comparison of Teaching Workloads of Academicians Based on Working Periods During and Before the COVID-19 Pandemic
    (Başkent Üniversitesi Mühendislik Fakültesi, 2025-01-25) Yorulmaz, Muhammed; Can, Gulin Feryal; Toktas, Pelin
    The COVID-19 pandemic has had a profound impact on society, greatly changing the structure of social and working lives. Educational institutions, especially in higher education, were forced to suspend face-to-face education and switch to distance education. This change inevitably affected the working styles and workloads of academics. This study aims to explore the effects of the COVID-19 pandemic on academic teaching workloads by examining transaction data for a one-year period before and during the pandemic. The data were obtained from the system logs of a learning management system platform, which was used extensively during the pre-pandemic and pandemic periods, and were analyzed in terms of transaction density, day, and time of transactions. The findings from the pre-pandemic period showed that the academic workload was higher on weekdays than on weekends. However, with the transition to distance education during the pandemic, the difference between weekday and weekend workloads diminished significantly. Additionally, the working hours shifted during the pandemic by approximately one hour to later hours in the day.

    Is There A Relationship Between The Severity Of Disease İn Major Depressive Disorder Patients And Dry Eye Disease?
    (Başkent Üniversitesi Fen Edebiyat Fakültesi, 2024-04-05) Gokce, Gizem Dogan; Metin, Merve
    PurposeTo investigate dry eye disease (DED) in newly diagnosed patients with depressive disorder (MDD). MethodThis observational study included 48 MDD patients in Group 1 and 20 healthy controls in Group 2. Psychiatric and ophthalmic examinations, Beck Depression Inventory (BDI), Ocular Surface Disease Index (OSDI), Schirmer's test, tear breakup time (TBUT), Meibomian gland dysfunction (MGD), and ocular staining were conducted. The results were statistically compared. ResultsThe participants, comprising 32 men and 36 women, had a mean age of 31.08 +/- 11.7 years (18-64 years). Group 1 had a mean BDI score of 30.87 +/- 8.56, while Group 2 had a score of 1.3 +/- 1.3 (p < 0.001). In Group 1, 28 patients were diagnosed with DED, whereas in Group 2, six subjects were diagnosed with DED. The mean Schirmer's results in Group 1 and Group 2 were (mm/5 min) 10.87 +/- 2.44 and 12.70 +/- 2.3, respectively, and were significantly lower in Group 1 (p < 0.001). The mean OSDI scores in Group 1 (34.95 +/- 15.8) were significantly higher compared to Group 2 (3.2 +/- 3.1) (p < 0.001). There was no significant difference in mean TBUT between Group 1 (9.41 +/- 2.6 s) and Group 2 (9.8 +/- 0.61 s) (p > 0.05). Significant correlations were found between BDI scores and Schirmer's results as well as OSDI scores (p < 0.05, p = 0.02, respectively). No statistically significant correlations were found between BDI scores and TBUT or MGD (p > 0.05). ConclusionDED was found to be more prevalent in the MDD group. The severity of MDD and DED, as indicated by BDI, OSDI, and Schirmer's results, was found to be correlated. It was observed that patients with higher depression scores had more severe dry eye. As a result, we recommend performing ophthalmic examinations in newly diagnosed MDD patients.

    Observational Tests Of Asymptotically Flat r2 Spacetimes
    (Başkent Üniversitesi Mühendislik Fakültesi, 2024-04-07) Zhu, Tao; Nguyen, Hoang Ky; Azreg-Ainou, Mustapha; Jamil, Mubasher
    A novel class of Buchdahl-inspired metrics with closed-form expressions was recently obtained based on Buchdahl's seminal work on searching for static, spherically symmetric metrics in R-2 gravity in vacuo. Buchdahl-inspired spacetimes provide an interesting framework for testing predictions of R(2 )ravity models against observations. To test these Buchdahl-inspired spacetimes, we consider observational constraints imposed on the deviation parameter, which characterizes the deviation of the asymptotically flat Buchdahl-inspired metric from the Schwarzschild spacetime. We utilize several recent solar system experiments and observations of the S2 star in the galactic center and the black hole shadow. By calculating the effects of Buchdahl-inspired spacetimes on astronomical observations both within and outside of the solar system, including the deflection angle of light by the Sun, gravitational time delay, perihelion advance, shadow, and geodetic precession, we determine observational constraints on the corresponding deviation parameters by comparing theoretical predictions with the most recent observations. Among these constraints, we find that the tightest one comes from the Cassini mission's measurement of gravitational time delay.

    Azoles Display Promising Anticonvulsant Effects Through Possible Ppar-Α Activation
    (Başkent Üniversitesi Eczacılık Fakültesi, 2024-05-25) Sari, Suat; Yurtoglu, Sibel; Zengin, Merve; Marcinkowska, Monika; Siwek, Agata; Sarac, Selma
    Azoles such as nafimidone, denzimol and loreclezole are known for their clinical efficacy against epilepsy, and loreclezole acts by potentiating gamma-aminobutyric acid (GABA)-ergic currents. In the current study, we report a series of azole derivatives in alcohol ester and oxime ester structure showing promising anticonvulsant effects in 6 Hz and maximal electro shock (MES) models with minimal toxicity. The most promising of the series, 5f, was active in both 6 Hz and MES tests with a median effective dose (ED50) of 118.92 mg/kg in 6 Hz test and a median toxic dose (TD50) twice as high in mice. The compounds were predicted druglike and blood-brain barrier (BBB) penetrant in silico. Contrary to what was expected, the compounds showed no in vitro affinity to GABAA receptors (GABAARs) in radioligand binding assays; however, they were found structurally similar to peroxisome proliferator-activated receptors alpha (PPAR-alpha) agonists and predicted to show high affinity and agonist-like binding to PPAR-alpha in molecular docking studies. As a result, 5f emerged as a safe azole anticonvulsant with a wide therapeutic window and possible action through PPAR-alpha activation.
