    Abstract Background: This study evaluated the shear bond strength (SBS) of two different polyetheretherketone (PEEK) and CAD-CAM materials after aging.
    Methods: A total of 42 frameworks were designed and milled from 2 different PEEK discs (Copra Peek, P and BioHPP, B). P and B frameworks were divided into 3 subgroups (n = 7). 14 slices were prepared each from feldspathic ceramic (Vitablocs Mark II, VM), hybrid nanoceramic (Cerasmart, CS), and polymer-infiltrated ceramic (Vita Enamic, VE) blocks. After surface preparations, the slices were cemented to P and B surfaces. The samples were subjected to thermal aging (5000 cycles). SBS of all the samples was measured. Fractured surfaces were examined by SEM/EDX analysis. The Shapiro-Wilk, Two-way Robust ANOVA and Bonferroni correction tests were used to analyze the data (a = .05).
    Results: Frameworks, ceramics, and frameworks x ceramics had significant differences (p < 0.05). The highest SBS value was seen in B-VM (p < 0.05). VM offered the highest SBS with both P and B. The differences between P-VM, P-CS, P-VE and B-CS and B-VE were insignificant (p > 0.05). According to EDX analysis, ytterbium and fluorine was seen in B content, unlike P. While VM and CS contained fluorine, barium, and aluminum; sodium and aluminum were observed in the VE structure.
    Conclusion: Bonding of P and B with VM offers higher SBS. VM, CS and VE did not make any difference in SBS for P, however VM showed a significant difference for B.

    Abstract Background: Turkey has one of the highest death rates in the world due to COVID-19 pandemic. The pandemic caused anxiety and depression in individuals. However, there is insufficient information on the effects of COVID-19 on individuals and their coping methods. Therefore, mental problems associated with the pandemic need to be evaluated rapidly.
    Aims: This study was carried out to determine depression levels and related factors in a society affected by COVID-19.
    Method: The study was planned using a descriptive cross-sectional design. The study started 2 weeks after the first diagnosis of COVID-19 in Turkey and was carried out between March 23 and April 3, 2020. The study included 1115 adult participants who were between 18 and 65 years of age and were citizens of the Turkish Republic. The study was carried out using online questionnaires, and data were collected with the Personal Information Form and the Beck Depression Inventory. The data were evaluated using IBM SPSS Statistics, version 20 software program.
    Results: The depression scores of female participants who were between 18 and 29 years of age, single, students, and had less income than their expenses were found to be higher than others. People who experienced fear of being infected and infecting others, had a cleaning obsession, anxiety about the future, sadness, and anxiousness experienced depression at lower levels when compared to other participants. Participants who had to change their place of residence during the quarantine, experienced loneliness, fear of death, hopelessness, sleep problems, felt useless and worthless, started to smoke and drink alcohol, and experienced depression at moderate levels. Depression scores of those who spent time with their family, made time for themselves, were busy with home education or work were lower compared to others.
    Conclusion: The COVID-19 pandemic caused mild-level depression in the Turkish society.

    Abstract Background: The aim of this study was to analyze and discuss the obstetric data of Türkiye in 2016 according to the Robson 10 Group Classification System.
    Methods: Data related to classification according to The 10-Group Classification System were prospectively collected in university hospitals, private hospitals and public hospitals in 2016 in Türkiye. All pregnant women admitted to labour and delivery wards were included in the study and were classified according to the Robson classification.
    Results: According to 2016 data in Türkiye, 649,212 of 1,189,578 deliveries were performed by cesarean section and the rate of cesarean section in overall was 54.6%. The cesarean section rates were 38.6%, 68.9%, 70.6%, in public hospitals, university hospitals, private hospitals, respectively (P<0.001). Robson 1 and 2 groups constitute 33.4%, Robson 3 and 4 groups 30.4% and of Robson 5 group 25.1% of all births. The contribution rate of the Robson 5 group to the cesarean section burden is 24.3/54.6%.
    Conclusions: Türkiye 2016 cesarean section data revealed the necessity of taking initiatives (establishing vaginal birth clinics after cesarean, developing clinical protocols, providing physical and emotional support) to reduce the cesarean section burdens seen in Robson 1, 2 and 5 groups.

    Abstract Özet Amaç. Araştırma, bir çocuk hastanesinde yatan 6-12 yaş çocuklarda psikososyal semptomların incelenmesi amacıyla yapılmıştır. Yöntem. Tanımlayıcı nitelikteki bu araştırmanın örneklemini, Gaziantep Çocuk Hastanesi’nde yatmakta olan, akut veya kronik bir hastalık tanısı almış ve herhangi bir psikiyatrik hastalık tanısı almamış, en az üç gündür hastanede yatan, çalışmaya katılmaya istekli, 6-12 yaş grubundaki 360 çocuk oluşturmuştur. Verilerin toplanmasında hastaların tanıtıcı özelliklerini belirleyen “Kişisel Bilgi Formu” ve “Hastanede Yatan Çocuklar İçin Psikososyal Semptomları Tanılama Ölçeği” kullanılmıştır. Veriler t testi ve Kruskal Wallis testle değerlendirilmiştir. Bulgular. Yaş ortalaması 8,8±2,0 olan çocukların, ,9’u erkek, ,2’si iki ve daha fazla sayıda hastanede yatmıştır. Ailesinin geliri giderinden az olan, köyde yaşayan, okula gitmeyen, iki kardeşi olan, üriner sistem ve endokrin sistemle ilgili hastalığı olan, 15 günden daha fazla süredir hastanede yatan ve psikiyatrik belirti öyküsü olan çocuklarda psikososyal semptomların daha fazla görüldüğü belirlenmiştir. Sonuç. Sonuç olarak özellikle psikiyatrik semptom öyküsü olan, uzun süredir hastalık semptomları yaşayan, iki ve daha fazla hastaneye yatma öyküsü olan ve sosyoekonomik durumu yetersiz çocuklara dikkat edilmesinin önemine vurgu yapılmıştır. Çalışmamızda hastanede yatan çocukların psikososyal açıdan değerlendirilmelerinin gerekli olduğu vurgulanmıştır.

  9. Article: Üniversite Son Sınıf Öğrencilerinin İş Bulmaya İlişkin Umutsuzluk Düzeylerinin İncelenmesi

    Abstract Bu çalışma üniversite son sınıf öğrencilerinin iş bulmaya ilişkin umutsuzluk düzeylerinin bazı değişkenler açısından incelenmesi amacıyla yapıldı. Tanımlayıcı nitelikteki bu çalışma, Amasya Üniversitesi fakülte ve yüksekokulunda 2012-2013 eğitim-öğretim yılında okuyan toplam 688 son sınıf öğrencisine uygulandı. Verilerin toplanmasında 20 soruluk kişisel bilgi formu ve 20 maddeden oluşan Beck Umutsuzluk Ölçeği kullanıldı. Veriler bilgisayar ortamında Mann Whitney U, Bonferroni ve Kruskal Wallis H Testleri yapılarak değerlendirildi. Okunulan bölümler arasında toplam umutsuzluk puanları açısından istatistiksel olarak anlamlı derecede farklılık olduğu saptandı (p<0.05). Eğitim fakültesinde okuyan öğrencilerde sağlık yüksekokulunda okuyan öğrencilere göre, erkeklerde de kadınlara göre toplam umutsuzluk puanlarının anlamlı derecede yüksek olduğu bulundu (p<0.05). Beden Eğitimi Öğretmenliği Bölümü öğrencilerinin en yüksek umutsuzluk puanına sahip oldukları (10.07) ve Okul Öncesi Öğretmenliği Bölümü öğrencilerinin umutsuzluk puanlarının düşük olduğu (3.82) saptandı. 20 yaş grubunda olan, ailesinin yanında kalan, akademik başarısını iyi olarak nitelendiren, üniversitede alınan eğitimin iş yaşamı için yeterli olduğunu düşünen, iş bulma süresinin 6 aydan kısa olacağını ifade eden öğrencilerin toplam umutsuzluk puanlarının anlamlı derecede düşük olduğu görüldü. Üniversite son sınıf öğrencilerinde iş bulmaya ilişkin umutsuzluk düzeylerinin bazı değişkenlere göre anlamlı derecede farklılık gösterdiği saptandı. Umutsuzluk düzeyine etki eden faktörlere yönelik öğrencilerin eğitim süresi boyunca desteklenmesi ve mezuniyet sonrası çalışma olanaklarının geliştirilmesinin gerekli olduğu düşünülmektedir.
