    Attention to the environment¡ green nature and public health in the most countries with continual climate change and unstable local weather was increased. As we know¡ by exciting the lower layers of the atmosphere¡ scientists can directly effect on the controversial climate. Hence¡ the scientific strategies and industrial policies in developed countries are rotating around equipment upgrades and the acquisition of new technologies in this field. Climate changes in the world¡ leading to increase or decrease rainfall. Formation of local rain¡ storm and fog are the results of condensed particles in the cloud. So by this mechanism we can artificially effect on the air and cloud¡ it is the main cause for climate change issues in the atmosphere physics dialogues. Hence¡ the special and unique management strategies for regional climate change is using methods that can help us to achieve controlling way to decrease or increase local rainfall and precipitations. To achieve this goal¡ it is artificially possible by effecting of the macro electrical discharge systems on the lower layers of the atmosphere. Using high technologies with optimization of the equipment¡ we can efficiently effect on decreasing of climate changes.

    Due to the rapid development of computer networks¡ Intrusions and attacks into these networks have grown¡ and occur in various ways. To resist against hackers and intrusive behaviors¡ several algorithms have been introduced in literature known as intrusion detection methods. The aim of intrusion detection is to identify unauthorized use¡ misuse¡ and vulnerability made by internal users or external attackers. The proposed method¡ based on misuse detection¡ extracts required knowledge from fuzzy system which is a set of fuzzy if-then rules¡ and performs the intrusion detection process. . In fact¡ the mentioned knowledge is considered as a fuzzy rule base which is optimized during the data mining process by an optimization algorithm according to some criteria such as accuracy and comprehensibility. Tabu search algorithm is employed to optimize the obtained set of fuzzy rules. Finally¡ the proposed method is implemented and applied to the NSL-KDD dataset which contains some information about normal and intrusive behaviors in computer networks. The results are compared with those of well-known methods¡ and show the competitive accuracy and efficiency.

    Borrowing the language of the world of the time¡ according to the degree of dynamism¡ is variable. The use of a common vocabulary between languages ¡ does not have a twofold advantage. Colloquial dialects¡ and languages that are not among the living languages of the world¡ of verbal interaction¡ marginalized¡ and gradually tend to forget. Today¡ Arabic and English¡ the languages of the world¡ due to technological advances¡ scientific discovery and dissemination of religious beliefs among different nations¡ lexical and semantic overlapping
    One of the distinguishing characteristics of the words between language¡ political aspect that politicians¡ to conquer new territories¡ ritual and its missionaries to these countries¡ - to algebra or injected Akhtyar-In this course¡ the influence of slang words between the two languages¡ and in a subtle way through the host country language and literature. This study establishes some consonants and pays words¡ that throughout history¡ the influence of Islam and Islamic scholars and Western European regions reached¡ and the interplay double as part of functional words are visible on both sides

    By entering into the third millennium, educational systems play an important role in the education and development of human resources, economic, social, cultural and political growth and development. Accordingly, one of the ways by which we can hope to achieve development is proper and systematic planning of resources and especially human resources in each country and efficient use of it. With regard to this fact that the main driven of development is human and first step in development is human capital formation. Therefore, investing in the education system as a determining strategy plays an important role in the economic, social, cultural and political growth and development of societies. Therefore, today we are facing unbreakable bond of educational planning and development programs. This is a Descriptive- Analytical study which aims to examine the role of educational planning in achieving national development programs. The results showed that to provide integrated educational system and national development plans, development components should be integrated with the education system, then with establishing a balance and harmony between its various components, necessary contexts will be provided in the course of development.

    The exact purpose of the NGOs (civil societies) is not clear and so the variety of NGOs (civil societies) may be in the form of various associations¡ organizations¡ institutions¡ foundations¡ institutes¡ cooperatives¡ clubs¡ groups and staff. Considering that these enterprises as independent entities and no dependence on the government and play a role for voluntary and non-profit and non-political purposes for the existence¡ so crime prevention plays a very to have an effective and in reducing crime and making them especially the role of prevention. NGOs (civil societies) through dissemination and public notification (communication) ¡ attracting public partnership (general mobilization) ¡ small grassroots fundraising and resources (resource mobilization) ¡ creating expanding and strengthening of coordination between the state that continues still¡ expanding the general monitoring and evaluation activities¡ increase efficiency in the use of resources to act in the normalization between the three topics of ¡popular participation¡ ¡mobilization of resources¡ and ¡monitoring and evaluation¡ and the importance of their role in the matter of high prevention plays a very noteworthy to say the failure of social deviations began fighting approaches and prevention of crime has caused the recent governments of about half a century to adopt participatory approaches in criminal policy¡ especially on the prevention of crime. This is the approach that it calls «criminal policy» that will be remembered for a participatory which means the company is giving people in various stages of the criminal justice system. One of the templates for the turnout in the field of crime prevention is the non-governmental organization because of the systematic¡ objective and being specialized of the effectiveness and the impact of a large enterprise.
