Coda Wave Attenuation Characteristics for North Anatolian Fault Zone, Turkey

North Anatolian Fault Zone, on which large earthquakes have occurred in the past, migrates regularly from east to west, and it is one of the most active faults in the world. The purpose of this study is to estimate the coda wave quality factor (Qc) for each of the five sub regionsthat were determined according to the fault rupture of these large earthquakes and along the fault. 978 records have been analyzed for 1.5, 3, 6, 9, 12 and 18 Hz frequencies by Single Backscattering Method. Along the fault, the variations in the Qc with lapse time are determined via, Qc = (136±25)f(0.96±0.027), Qc = (208±22)f(0.85±0.02)Qc = (307±28)f(0.72±0.025) at 20, 30, 40 sec lapse times, respectively. The estimated average frequency-dependence quality factor for all lapse time are; Qc(f) = (189±26)f(0.86±0.02) for Karliova-Tokat region; Qc(f) = (216±19)f(0.76±0.018) for Tokat-Çorum region; Qc(f) = (232±18)f(0.76±0.019) for Çorum-Adapazari region; Qc(f) = (280±28)f(0.79±0.021) for Adapazari-Yalova region; Qc(f) = (252±26)f(0.81±0.022) for Yalova-Gulf of Saros region. The coda wave quality factor at all the lapse times and frequencies is Qc(f) = (206±15)f(0.85±0.012) in the study area. The most change of Qc with lapse time is determined at Yalova-Saros region. The result may be related to heterogeneity degree of rapidly decreases towards the deep crust like compared to the other sub region. Moreover, the highest Qc is calculated between Adapazari – Yalova. It was interpreted as a result of seismic energy released by 1999 Kocaeli Earthquake. Besides, it couldn’t be established a causal relationship between the regional variation of Qc with frequency and lapse time associated to migration of the big earthquakes. These results have been interpreted as the attenuation mechanism is affected by both regional heterogeneity and consist of a single or multi strands of the fault structure

Self-esteem and quality of life in bariatric surgery candidates

WOS: 000455891800003Objective: The basic aim of this study was to explore the differences between bariatric surgery candidates (BSC) and control group in self-esteem and quality of life. In addition, our secondary aim is to find out the relationship between self-esteem and quality of life in bariatric surgery candidates. Methods: The study involves a group of BSCs screened at Haydarpasa Numune Training and Research Hospital. Sixty-one consecutive BSCs and control group assessed by Short Form-36 (SF-36), Rosenberg Self-Esteem Scale and Beck Depression Inventory (BDI). Control group was constituted from 61 normal-weight employees from the same hospital. Results: BSCs group consisted from 50 women and 11 men. BSCs scored statistically lower on all the SF-36 subscales, BDI and self-esteem scale compared with controls. The rates of having a lifetime psychiatric disorder and having any comorbid medical condition in the BSCs were statistically significantly higher than the control group. Because of regression analysis, mental health subscale score of SF-36 and BDI score were found to have the most effect on self-esteem in BSCs group. Conclusion: Self-esteem and quality of life are interrelated concepts in BSCs. Self-esteem is most commonly associated with mental health and depression levels as expected. Psychiatric follow-up has a great importance in evaluation and treatment of these patients

Effects of psychiatric symptoms, age, and gender on fear of missing out (FoMO) and problematic smartphone use:Apath analysis with clinical-based adolescent sample

Background: Fear of missing out (FoMO) is a kind of anxiety that arises from FoMO on rewarding online social experiences that others might be having. Recent studies demonstrated that there is a strong relationship between FoMO and problematic smartphone use (PSU). In this study, we aimed to address the relationship between age, gender, psychiatric symptoms, PSU, and FoMO among a clinical-based adolescent sample. Methods: In total, 197 adolescents (136 boys, 1218 years) who applied to psychiatry clinics were recruited in the study. Path analysis with observed variables was used to investigate the relationships of PSU and FoMO with each other and with psychiatric symptoms (somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, phobic anxiety, paranoid ideation, and psychoticism), age, and gender. Results: Path analysis showed that age (B-1 = 2.35, P < 0.001), somatization (B1 = 1.19, P < 0.001), hostility (B-1 = 0.92, P = 0.001), and paranoid ideation (B-1 = 0.93, P = 0.005) have significant positive effect on PSU, when interpersonal sensitivity has a significant negative effect (B-1 = -1.47, P < 0.001). For FoMO, male gender (B-0 = 0.35, P < 0.001), anxiety (B-1 = 1.37, P < 0.001), and PSU have positive effects, whereas age (B-1 = -1.60, P < 0.001), depression (B-1 = -0.58, P = 0.004), and hostility (B-1 = -0.49, P = 0.001) have a negative effect. Conclusions: Our study demonstrated that although PSU and FoMO are closely related to each other in previous studies, they have different associations with age, gender, and psychiatric symptoms among a clinical-based adolescent sample. The positive effects of PSU, anxiety on FoMO are predictable; however, the negative effect of age, hostility, and depression on FoMO was interesting. These relationships could be related to social exclusion-hostility and impulsivity-male gender/younger age associations in adolescence. In addition, we did not find a significant effect of FoMO on PSU, this could be related to the social and non-social use of smartphones, and should be reevaluated in clinical samples in the future

Kilic, Birim Gunay/0000-0002-4566-2564; Bahadir, Gulnur Gollu/0000-0001-8163-2226; Sertcelik, Mehmet/0000-0001-7031-3318; Soyer, Tutku/0000-0003-1505-6042WOS: 000352140500009PubMed: 25840059Background/aim: Children with attention-deficit/hyperactivity disorder (AD/HD) have risk taking behavior and are more prone to sustaining injury. It is aimed to evaluate the cognitive and behavioral characteristics of children with caustic ingestion. Patients and methods: Ninety two children with a history of nonsuicidal caustic ingestion (CI, n = 46) and healthy subjects (HS, n = 46) admitted to pediatric surgery department were enrolled into the study. Patients in groups were evaluated for age, sex, number of siblings and educational status of the parents. Before filling the questionnaires, the children were undergone flexible endoscopy and treated accordingly. Conners Parents Rating Scale-revised long form (CPRS-R:L), validated for Turkish Children, was used to evaluate the cognitive and behavioral characteristics of children. Parents rate their child's behavior with a four-point Likert scale. Subscales of CPRS-R: L including cognitive problems/inattention (CG/I), hyperactivity (H), attention deficit hyperactivity disorder index (AD/HD-I), Conners' Global Index-discomfort-impulsivity (CGI-DI), DSM-IV-symptom subscale-inattention (DSMIV, SS-I), DSM-IV-symptom subscale-hyperactivity-impulsivity (DSM-IV, SS-HI), DSMIV-symptom subscale-total score (DSM-IV SS-T) were used to determine the severity of the AD/HD symptom. Demographic features and cognitive/behavioral characteristics of children with caustic ingestion were compared with healthy subjects. Results: The median age of the patients was 4 (2-14 years) in both CI and HS groups. Female male ratio was 13:33 in CI and 12:34 in HS. Sixty seven percent of patients were preschool children (younger than 5 years of age) in both CI and HS groups. There was no difference between groups for number of siblings (p > 0.05). Parents of HS group had higher educational status than parents in CI (p < 0.05). When subscale scores of CPRS-R: L compared between CI and HS groups, CI group had higher CGI-DI scores than HS (p < 0.05). Children younger than five years of age had higher scores of H, emotional instability and total CG/I in CI than HS group (p < 0.05). Conclusion: Children with caustic ingestion had impulsiveness behavior when compared to healthy children. In addition to impulsivity, hyperactivity can be also assessed as a risk factor for caustic ingestion in children younger than 5 years of age. We suggest that association between AD/HD behavior and risk of sustaining injuries was also confirmed for caustic ingestion in children. (C) 2015 Elsevier Inc. All rights reserved

Prevalence of Childhood Affective disorders in Turkey: An epidemiological study

Aim: To determine the prevalence of affective disorders in Turkey among a representative sample of Turkish population. Methods: This study was conducted as a part of the "The Epidemiology of Childhood Psychopathology in Turkey" (EPICPAT-T) Study, which was designed by the Turkish Association of Child and Adolescent Mental Health. The inclusion criterion was being a student between the second and fourth grades in the schools assigned as study centers. The assessment tools used were the K-SADS-PL, and a sociodemographic form that was designed by the authors. Impairment was assessed via a 3 point-Likert type scale independently rated by a parent and a teacher. Results: A total of 5842 participants were included in the analyses. The prevalence of affective disorders was 2.5 % without considering impairment and 1.6 % when impairment was taken into account. In our sample, the diagnosis of bipolar disorder was lacking, thus depressive disorders constituted all the cases. Among depressive disorders with impairment, major depressive disorder (MDD) (prevalence of 1.06%) was the most common, followed by dysthymia (prevalence of 0.2%), adjustment disorder with depressive features (prevalence of 0.17%), and depressive disorder-NOS (prevalence of 0.14%). There were no statistically significant gender differences for depression. Maternal psychopathology and paternal physical illness were predictors of affective disorders with pervasive impairment. Conclusion: MDD was the most common depressive disorder among Turkish children in this nationwide epidemiological study. This highlights the severe nature of depression and the importance of early interventions. Populations with maternal psychopathology and paternal physical illness may be the most appropriate targets for interventions to prevent and treat depression in children and adolescents
