تحديات العولمة للشباب ومواجهتها في ضوء السيرة النبوية

Challenges are part of the ways of life, and the Islamic world is suffering of the rupture and differentiates internal conflicts, and the chaos of thought and delayed civilization. The most prominent of these challenges, which the Islamic world is facing, is the phenomenon of globalization. Which included the three worlds, and sought to dominate them, and melt the people’s properties and this is what precipitated the emergence of numerous drawbacks, and the researcher specially mentioned, negative aspects of identity, ethics and the environment. Young people who are the hope and asset of this nation are able to turn dreams into realities, and hopes to practical projects, and ambitions to the visible achievements. They are worthwhile, and the most capable and powerful to meet these challenges. If they grasp the necessary requirements that qualify and stables them to face it and take advantage of its goodness, and avoid disadvantage. But if they stationed, and failed to do their duty, they offered loss and destruction to themselves and nation. Curriculum should be prepared in accordance with the system of Islamic values, which are the individual configuration integrated, in belief, thought, and behavior, and attention to the development of the curriculum, and make it combines tradition and modernity, and the distinction between fixed and variable, and have superior mental abilities. All these issues are addressed in this research the negative impact of globalization on the environment, ethics and then showed the importance of taking care of the human development of young people, through various training programs that earn young people skills, science, and sophisticated learning methodical thinking, proper planning, and positive participation in society, and carry responsibility, and foster in them the ability to dialogue and to develop in them the spirit of creativity and scientific research and rational dealing with crises, and tribulations, and the ability to solve problems and meet the challenges of globalizatio

Hermitian ricci tensor of twistor space

Twistor Space was first described by Roger Penrose and Malcolm MacCallum in the 1960s. Let (N, h) be an oriented Riemannian 4-manifold" then twistor space of (N, h) is the two-sphere subbundle W of A~T N which has an l-parameter family of Riemannian metric gr. The Ricci curvature of (W, gt) was defined in [9]. In [6], G. Deschamps defined almost complex (a.c) structures 3j on a manifold W of dimension 6 under a fiber preserving morphism j: W ---7 W of the bundle W such that n 0 j = Jr. The Ricci tensor of the twistor space of an almost Hermitian Riemannian 4-manifold was also discussed w.r.t an a.c structure. defined with the help of the morphism j: W ---7 Wand a sectionj3 E A2T N in [10] which is a particular case of the arbitrary morphism f. In this dissertation, I studied the Ricci tensor of (W, gt) and the conditions in which the Ricci tensor of twistor space with almost Hermitian base manifold is also Hermitian correspond to the a.c structure 5. Furthermore, we can also explore the conditions for the Ricci tensor of (W, gt) to be Hermitian corresponding to the complex structure 3) defined under an arbitrary fiber preserving map from the twistor space W to W
