Faced with this fact, how are architects to responsibly pursue the act (and art) of building without further deteriorating the planet's environmental make-up or depleting its resources? What forms of high and low technology can be developed to curtail the injurious side of building? Can good or even great architecture be sustainable? In this paper discuss the problem such as: The Future Is Green: Architecture + Sustainability and have been surveyed Green Architecture and impacts of it on urban planing and urban design.

Security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision.

Today, there is a growing trend towards qualitative research in different areas of academic investigations. However, students face difficulties in deciding on qualitative methods of research, because most of the literature on qualitative research focuses on the philosophical and theoretical aspects, and they hardly offer any practical guidelines. This problem is rooted in the essence of qualitative research, which makes the details of the research process unachievable at the beginning. As a result, the features of the sampling plan—like the accurate size and form of the sampling—remain uncertain until after the data has been gathered, and this makes the jury doubtful about the approval of the research proposal. Hence, framing an appropriate and assayable plan for sampling can be of great help in the approval and execution of qualitative research plans. From this perspective, the present article aims to design a framework for a sampling plan in qualitative researches using theoretical sources of the grounded theory method and researchers’ suggestions based on practical involvement, as well as the recent experience of the authors in grounded theory research. By studying these sources, and considering the feedback for and practical involvement in the grounded theory method, a two-stage plan of sampling is proposed. The initial stage aims to ensure adequate diversity for the appropriate distribution of the samples, and the second, as a theoretical sampling stage, guarantees the theoretical attribute of sampling in qualitative research.

Participation of people in their cities and neighborhoods has always been emphasized by researchers and experts in order to improve the quality of citizens’ life and having efficient urban management. However, it seems that providing participation contexts at local level by citizens needs preparations and substrates that facilitate participation. In the meantime, establishing a neighborhood management plan in order to provide participation contexts at local level by citizens can be considered as a movement in this regard. Accordingly, the purpose of the present research is to evaluate the relationship between neighborhood involvement sense and social participation of citizens. In this regard, Kuti neighborhood of Bushehr, which has valuable activity, physical, and social features, is investigated as a sample. In the present research, the research method is operational based on the purpose and descriptive-analytical and experimental-surveying based on the method. Thus, library studies have been used to explain literature and history of the research subject, and field methods have been used to collect data according to the nature of the research. The data were collected by a questionnaire among 60 residents of the Kuti neighborhood who were over 18 years old. The sampling method, used in this study, was random and SPSS software was used for data analysis. The results of this research indicate that there is a relationship between neighborhood involvement sense and preparation for participation. The correlation between these two variables was in the positive direction. In addition, by increasing the neighborhood involvement sense, the preparation for participation increases.
