Introduction: Adolescent are at high risk of unwanted pragnency, including abortion, STIs, HIV/AIDS. Risky sexual behavior is one of the entrance transmissions of unwanted pregnancy. Such behavior can be influenced by various factors, beyond and within the individual factors. Teens need the support and motivation in deciding not to do risky sexual behavior. The purpose of this study was to investigate the determinants of adolescent behavior in the prevention of unwanted pregnancy.Methods: This research used cross-sectional design. The populations were students of senior high school in District Sintang. The were 123 respondents chosen by cluster sampling technique for this study. All data were collected using questionnaires and then analysed using bivariate (chi square) and multivariate analysis (logistic regression).Results: The results showed that the majority of respondents did not have good knowledge about the prevention of unwanted pregnancy. Related variable is the level of parental education (p=0.001), the support of parents/guardians (p=0.009), support teachers (p=0.005), peer support (p=0.039), residency (p=0.009), a pastime activity (p=0.000), knowledge of adolescents about reproductive health (p=0.016), perception ability of adolescents (p=0.006) and attitude of adolescents (p=0.049). Adolescent self-perception abilities are variables that most influence on the behavior of adolescents in the prevention of unwanted pregnancy.Conclusions: Efforts to improve reproductive health programs should be early and adolescent have responsibilities as well as healthy behaviors.

Background and Aims: Temperament is determined as a relatively constant, basic, and innate position that underlies and modifies the expression of activity, emotionality, and sociability among people. The current study aimed to investigate the prediction of dark personality traits and self-destruction based on emotion regulation among adolescent females. Materials and Methods: This correlational study included 250 adolescent females using a cluster sampling method in the academic year of 2018-19 in Shiraz, Iran. The participants were asked to complete Difficulties in Emotion Regulation Scale, Dark Triad Scale, and Chronic Self-Destructiveness Scale. Results: The results of the regression analysis showed that emotion regulation with beta coefficients was able to predict significant and positive dark personality traits (0.25), narcissism (0.49), Machiavellianism (0.39), psychopathy (0.32), sadism (0.35), and self-destructiveness (0.49) (P<0.05). Conclusion: Directly targeted interventions to regulate emotion may be useful in addressing risky behaviors of adolescents with self-destructive and dark personality traits.

Conductive Thin Films

Electrical properties of conductive thin films, that are produced by vacuum evaporation on the dielectric substrates, and which properties depend on their thickness, usually are anisotropic i.e. they have uniaxial anisotropy. If the condensate grow on dielectric substrates on which plane electrical field E is created the transverse voltage U⊥ appears on the boundary of the film in the direction perpendicular to E. Transverse voltage U⊥ depends on the angle γ between the applied magnetic field H and axis of light magnetisation. When electric field E is applied to continuous or grid layers, U⊥ and resistance R of layers are changed by changing γ. It means that value of U⊥ is the measure of anisotropy magnitude. Increasing voltage U0 , which is created by E, U⊥ increases to certain magnitude and later decreases. The anisotropy of continuous thin layers is excited by inequality of conductivity tensor components σ0 ≠ σ⊥. The reason of anisotropy is explained by the model which shows that properties of grain boundaries are defined by unequal probability of transient of charge carrier.
