Methods: The study was conducted in the entire Gaza Strip 6 months after the end of the war on Gaza that lasted for 23 days. The study sample included 410 children aged 6 to 17 years. Children completed measures of experience of traumatic events (Gaza Traumatic Checklist-War on Gaza), post traumatic stress disorder index, attention deficit with hyperactivity scale for parents and self, conduct disorder scale, and oppositional defiant disorder. Results: Palestinians children investigated 6 months after the war on Gaza still reported traumatic experiences: 94.6% heard the sonic sounds of the jet fighters, 91.7% heard shelling of the area by artillery, 92% watched mutilated bodies on television, 80% were deprived from water or electricity during the war, 50.7% said they left home for safer place. Using Diagnostic Manual of Mental Disorders-IV (DSM-IV) criteria for post traumatic stress disorder, 25.1% of children reported no psychological reactions, 25.9% of children reported one criteria, 39.3% of children reported partial post traumatic stress disorder and 9.8% of children reported full criteria for post traumatic stress disorder. According to the parents’ report, the results showed 31.3% of children met the criteria for inattentive type, 36.3% of children were impulsive and 29% met criteria for combined type. According to the children’s report, the results showed 28.8% of children met the criteria for inattentive type, 37.3% of children were impulsive and 28.3% met criteria for combined type. Using DSM-IV diagnostic criteria of conduct disorder and oppositional defiant disorder, the study showed that 38.1% of parents reported conduct disorder in their children and 46.3% reported oppositional defiant disorder. While 39.3% of children themselves reported conduct disorder and 44% of them reported oppositional defiant disorder. The study showed that 5.1% of children had comorbidity of post traumatic stress disorder and attention deficit disorder, 4.4% had comorbidity of post traumatic stress disorder and impulsivity-hyperactivity disorder, and 4.4% had comorbidity of post traumatic stress disorder and attention deficit with hyperactivity combined type. Also, 4.6% of children had comorbidity of conduct and post traumatic stress disorder and 6.1% had comorbidity of oppositional defiant disorder and post traumatic stress disorder. Conclusions: This study revealed that children living in areas of conflict and war are the main group at risk of developing post traumatic stress disorder and other behavioral problems including attention deficit with hyperactivity, conduct, and oppositional defiant disorder, and the internationallaws must protect the civilians during the conflict, establishing safe havens for children and their families to decrease the effect of war on children.展开更多

The thickness of the compound layer and the diffusion layer are about 10μm and about 200μm,respectively. Plasma post oxidation was performed on the nitrocarburized samples with various oxygen/hydrogen ratio at constant temperature of 500℃for 1 h.The very thin magnetite （Fe-3O-4） layer of 1-2μm in thickness on top of the compound layer was obtained.Anodic polarization test revealed that plasma nitrocarburizing process contributed a significant improvement of corrosion resistance of SKD 61 steel.However,the corrosion characteristics of the nitrocarburized compound layer was deteriorated by oxidation treatment.展开更多

Their evidence of efficacy has never been systematically reviewed. We searched PubMed, PsychInfo and the Dutch Tropical Institute Literature Portal from inception to31 January 2013 to identify studies on community-oriented psychosocial and psychiatric/clinical services for adults during ongoing manmade conflict or its direct aftermath. Of 6358 articles screened, 16 met our inclusion criteria. The interventions varied from psycho-educational to psychotropic drugs. The review is presented using outcome indicators such as PTSD, anxiety, depression, physical health, functioning and well being. A substantial improvement of some outcome was found though the small number of studies and their heterogeneity did not justify strong conclusions. PTSD symptoms improved significantly by treatments that included exposure (such as narrative exposure therapy). A number of studies (eight) showed notable improvement of the client’s functioning through counseling interventions. Depression and anxiety both improved considerably using that culturally adapted interventions (two studies), whereas non-culturalized interventions did not. We found a notable lack of studies on the efficacy of medication and on preferred western, evidence-based interventions for PTSD such Eye Movement Desensitization. To measure outcomes only two studies applied locally-developed diagnostic labels and validated instruments. Future research should encourage the use of robust research methods that are culturally valid, including mixed-methods research to combine measurable outputs with qualitative research aimed at improved understanding from the client’s perspective.展开更多

Plasma nitrocarburizing was conducted for 3 h at 570 ℃ in the nitrogen, hydrogen and methane atmosphere to produce the ε-Fe2-3(N,C) phase. It was found that the compound layer produced by plasma nitrocarburising was predominantly composed of ε-phase, with a small proportion of γ′-Fe4(N,C) phase. The thickness of the compound layer was about 10 μm and the diffusion layer was about 300 μm in thickness, respectively. Plasma post oxidation was performed on the nitrocarburized samples with various oxygen/hydrogen ratio at a constant temperature of 500 ℃ for 1 h. The very thin magnetite (Fe3O4) layer 1-2 μm in thickness on top of the compound layer was obtained by plasma post oxidation. It was confirmed that the corrosion characteristics of the nitrocarburized compound layer can be further improved by the application of the superficial magnetite layer.展开更多
