The concept of space identity with human habitation in cognitive geography has been considered in recent decades. This concept is studied in the format land-meaningfulness which is human insight in dealing with space identity and original position of community life. The land-meaningfulness has given to the meanings of human of from space identity meaning and concept that manifests it in the type of social configuration. This research has studied the faulty identity of Qazvin Baghshahr configuration with the noumenonology method and within the framework of the Isfahan school. The gardens around the configuration of Qazvin Bagshahr are a smart and astutely dam against floods. In the configuration of Qazvin Baghshahr, several bio cryptography plexsuses have maintained its sustainability and durability until today. The results of this study are presented in three statements: Some cities of Iran land – context have a faulty identity, such as Qazvin Baghshahr configuration. People of Qazvin Baghshahr configuration have kept this configuration in a sustainable way for 1000 years with the land-meaningfulness which is recognition of space identity through the division of the amount of flood water in the scrolls and documents of water division and the spatial arrangement of fields and gardens. The survival of any geographical phenomenon like Qazvin Baghshahr configuration is the result of the bio cryptographys plexsuses stability and their mechanisms during the 1000-year period.

this paper classifies the amount and mechanisms in which the quality and desirability of walking experience in the urban shopping malls and centres. Thus, a literature review can classify the cases in 6 categories of social spatial factor, Attraction, convenience and comfort, a sense of security, access and permeability, way finding and legibility and social interactions. Collecting data was carried out in Kurdistan commercial complex located in Pasadaran Street of Sanandaj, which is also welcomed by both street strollers and a range of users. Due to unprecedented different spatial configuration of this shopping complex in the city, it can be considered as a new shopping centers. However, due to lack of well-known brands, due to the lack of a free and competitive economy, as well as considering other services and entertainment aspects, and the lack of defined standards of anchor stores, flow, it stands away from defined standard shopping centres and global wealth. However, organizing space and its form make it possible for behavioural settings interspersed with wandering around and pastime to form around. In the case study, the data related to 6 listed factors are mixed together with synthetic methods, and finally with the help of SPSS software, the interpretation of the results is provided with more documentation. In this regard, questionnaires were distributed among 110. Deep interviews were carried out with the respondents and behavioral settings and movement routes were designated through the acquisition of behavior maps, tracking, daily note-taking and photography. The main finding in this study is that the location of shopping centres and malls along the routes of circulation and urban strollers. In addition to considering the needs of individuals with shopping intention, wanderers should be paid attention to through designing their forms and functions supporting desirable behaviour. The findings stresses that this category of users, take advantage of the shopping centre and events as social and public places in order to experience a city walk, and less affected by the economic logic resulting from commodity relations in shopping malls and commodity relationships. Thus, with a focus on the behaviour of strollers, it is possible to improve the quality of social spatial centres as semi-public spaces, and on the other hand, to imagine them as future goals for shopping in shopping malls, a new door can be opened to design and management. Therefore, spatial configuration and geometry of the distribution and clustering compatible attractive functions and diversity of form and function in the outer shell are of high in making these types of shopping malls to places in which socialization and celebrations are allowed. Legible and specific permeability of the entrance, in the outer shell, paying attention to the clear connection of internal and external routes supporting the desired behaviours of strollers and their choices in space as well as the appropriate width of paths and routes without obstacles, connection between internal and external paths with urban pedestrians adjacent to site, are effective in the movement of users and their use of spaces.

The concept of configuration of groups which is defined in terms of finite partitions and finite strings of elements of the group is presented by Rosenblatt and Willis. To each set of configurations, a finite system of equations known as configuration equations, is associated. Rosenblatt and Willis proved that a discrete group G is amenable if and only if every possible instance of its configuration equations admits a normalized solution. In this paper we compare the existence of such solutions for different systems. We prove that if a system of configuration equations has no normalized solution, then every system related to a refinement of the initial partition, has no normalized solution, as well. The Tarski number of a non-amenable group is the smallest number of the pieces of its paradoxical decompositions. In the present paper we also provide a relation between the Tarski numbers of the subgroups of two configuration equivalent groups.

Purpose: Recognizing canal configuration is necessary for a correct endodontic therapy; and having no information about canal configuration causes failure in therapy. Since one of the most effective factors in canal configuration is race' we decided to have a laboratory and clinical research in Isfahan. The aim is to recognize canal configuration of the mandibular first premolar and compare the clinical and laboratory results.Methods & Materials: 1- Laboratory study (Invitro): At first we selected 127 mandibular first premolar' then we disinfected them in CLONA 5.25%. We made a correct access cavity on the teeth. In order to vacate pulp tissue in chamber and canals, we placed them in H2O2 35% for 15 days. Then we placed them in HNO3 5% for 3 days to be decalcified. Then we used 70%, 90%, 100% isopropyl alchole to dehidrate the teeth. After the above processes we injected India ink in -1.8 P, in canals and sealed access cavity by Zonaline cement, we used the teeth in Metyl Salicylate to make clear. Then, we studied canal configuration. 2- Clinical study (Invivo): In this study we selected 125 mandibular first premolar treated in post graduate and under graduate departments of Isfahan University school of Dentistry. Then we studied every radiograph using a negatoscope, and the data were analysed.Results: 1-Laboratory (invitro) results: Out of 112 mandibular first premolar (researchable), 75 type I (67%),5 type II (4.5%), 13 type III (11.6%), 16 type IV (14.2%) and 3 (2.7%) were out of Weine classification. 2-Clinical (invivo) results: Out of 125 mandibular first premolar, 103 type I (82.4%),3 type II (2.24%), 12 type III (9.66%), 5 type IV (4%) and 2 (1.66%) were out of Weine classification.Conclusion: The out coming results of this study are different from other researches. Perhaps the differences are caused by some factors such as race and method. Also the clinical results are too different from laboratory results which could be due to method. The laboratory study is more exact.
