Street theater is inherently different from the museum or socalled elite arts, and its artists use theater not as mere art, but as a tool working toward peace and as a counter-power in the fight against discrimination and inequality. Transcending the confines of the playhouse, street theater expands its scope of influence over streets and communities and goes beyond the traditional rules of the classical stage to establish a deeper connection with different audiences. Street theater is the voice of those who are cut off from mainstream media channels but still want to express their views. Street theater conveys alternative voices and beliefs, performs an effective socio-political function in society, and promises to make a positive change in the lives of everyone. It uses the power of collective participation—a vital force in human nature—to explore the adverse conditions in society and encourage individuals to make an effort to achieve collective growth. This study aimed to review the counter-power potentials of street theater. The results show that artists can employ the potentials of this theatrical form to free themselves from the cultural dominance of power institutions that dictate their own artistic values and contribute to the growth of society in social, political, educational, and cultural terms.

John Dewey thought that the mission of philosophy was social change, and the desired change could be achieved through education. Human growth is perpetual, and so education should not be limited to a specific period of life, rather it should be a part of the process of life. The class and school years always come to an end eventually, however, the influence of social educational institutions must be continuous. Cultural and artistic measures such as applied theaters are useful educational tools that can have a great effect on the moral growth and social life capabilities of the citizens. Augusto Boal developed the idea of the Theater of the Oppressed (TO) to reach the starting point of change in life. TO provides an opportunity for people in society to express their inner desires. Here, certain situations similar to reality are created, where the audience is allowed to practice and experience life, without having to endure losses and lose opportunities. This study was mainly based on secondary research using existing fundamental works on Dewey’s aesthetics and education philosophy, aiming to provide applied research for empowering Theater of the Oppressed (TO) and presenting solutions to increase its function. After a review of TO, the theater of the Rainbow of Desire was explored in a special section, showing that it is possible to improve the mental health of the spect-actors by creating sympathy among them and encouraging them toward expressive actions.

John Dewey thought that the mission of philosophy was social change, and the desired change could be achieved through education. According to Dewey, the sole purpose of education is to reform society and pave the way for social progress, thus demonstrating the necessity of education for the survival of society. Cultural and artistic venues such as educational theater are useful venues that can have great effects on moral growth and desired social change for their communities. Creative Drama provides an opportunity for people to express their inner desires. Here, certain situations similar to reality are created, where the audience is allowed to practice and experience life, without having to endure losses and lose opportunities. Dewey's aesthetic and educational theories can be useful in increasing the social and artistic function of creative drama.This study was mainly based on secondary research using existing fundamental works of Dewey's education philosophy and aesthetics, aiming to explore the effect and importance of theatrical plays as a means of promoting education in schools and the community at large. The main features of applied theater are introduced and suggestions are provided to increase the effectiveness and function of this art form as a way to improve people's social lives. For this purpose, after examining the basic concepts of Dewey's philosophy (e.g. pragmatism, experience, aesthetics, education, and the role of theatrical plays in education) certain and specific aspects of the applied theater are introduced. This study also included a case study of creative drama based on Dewey's educational theories. By re-reading creative drama, suggestions are presented in order to use Dewey's educational theories, hoping to help artists to take proactive steps in the field of education aimed at social awareness and change.According to Dewey, students develop in an educational setting where they can experience and interact with the issue at hand. Each and every student needs to play a role and cooperate in their learning process. Dewey believed problem-solving to be the best teaching method, fitting individuals for life and empowering them to solve problems in their personal lives and their social interactions. Problem-solving was deemed the best teaching method by Dewey, which leads to creative drama and its effectiveness since its base foundation is formed around the theory of problem-solving. The first step in creative drama is to tell a story to students thoroughly. This paper seeks to show that when a story is told to students incompletely, in order to be completed by them in a creative drama, a problem will be formed in their minds, encouraging them to solve it. If the content of creative drama is presented to learners in full detail, their mental engagement with the content will be reduced, and, consequently, their ability and motivation to interact will diminish. Performing creative drama based on problem-solving exposes students to the problem in a creative manner; they are encouraged to cooperate and think to bring the drama to a desirable end. Placed at the core of problem in creative drama, students are forced to think and provide solutions that ultimately are skills that they will need in their own lives.

Transcending the confines of the playhouse, street theater expands its scope of influence over streets and communities and goes beyond the traditional rules of the classical stage to establish a deeper connection with different audiences. Street theater artists commit themselves to the realities and issues of society and use the street theatre as a medium to make a difference in the lives of those people with whom conventional theater fails to communicate due to political, economic, and cultural reasons. John Dewey’s views on aesthetics and education seem useful for improving the social and artistic function of street theater, because he prioritizes the functional aspect of art, maintaining that for things to be valued by humans, they need to both fulfill human organismic needs and pave the way for the improvement of lives. To Dewey, the job of philosophy was creating social change, which, he believed, is achievable through education. Based on his point of view, experience shapes the basis of education, the goal of which is to prepare individuals for active and positive participation in society and, as he puts it, “achieving greater growth”. Conducted as desk research, the present study consulted Dewey’s philosophy of aesthetics and education to offer pragmatic ways to empower street theater. The effort found that by relying on Dewey’s ideas and by portraying themes of everyday life, this form of theater can make use of its potentials to change lives and inspire the social, individual, and moral growth of citizens. Moreover, street theater can create empathy among members of society, making them a united whole when it comes to tackling social issues. It is hoped that the study use of Dewey’s philosophy as a source can help street theater artists become accomplished social activists who make society a better place.

In this article, the effect of weight percentage of carbon than silicon in carbon equivalent and also increasing the percentage of phosphor to eliminate the melt penetration defect in grey cast iron parts using simulation software and molding machine (DISA 240 B), has been reviewed. Produced parts with 3.4 ~ 3.5 % carbon, 1.8 ~ 1.9 % silicon and 0.08 ~ 0.1 % phosphor are including mentioned defect. By keeping carbon equivalent fix and changing carbon percentage to 3.2 ~ 3.3, silicon to 2.25 ~ 2.35 and increasing phosphor up to 0.11 ~ 0.12, the melt penetration was decreased strongly. According to related reviews by simulation, Optic and scanning electron microscopes, it’s clear that this defect is eliminated by decreasing graphite expansion and increasing the melt fluidity.
