In developing countries, after decades passed from preparing urban development plans, informal settlements and urban decay are unresolved, but their scope and severity increase day by day. Therefore, ins tead of tracing the root of this problem in preparing and implementing plans, it should be viewed from another perspective and the hidden aspect of planning theory, i.e., the realm of power and its application to living space, mainly ignored by urban planners. The primary purpose of this s tudy is to inves tigate the genealogy of urban development plans in the Abkooh neighborhood to reflect the application of bio-power in the process of spatial planning. Using the social cons tructivism approach and accepting the transition of the capitalis t sys tem from imperialism to the empire, the current s tudy analyses two categories of power-knowledge: disciplinary power and bio-power and their relationship with spatial planning. Then, after describing the gray spaces, applying disciplinary power and bio-power in these spaces is discussed. Finally, Foucault's genealogical approach is performed to critically analyze the bio-power in urban development projects related to the Abkooh neighborhood. From Foucault's power-knowledge perspective, power relations seek to accumulate capital and commodify urban spaces through urban development plans and rely on disciplinary power and bio-power and using the formal spatial planning sys tem. The research findings prove that his torically, the formation of urban development plans is connected to the network of power relations. Therefore, spatial planners, besides attending planning approaches routinely learned in the academic environment, should also address power-knowledge issues.

The Iranian tribes have their unique architecture due to their lifes tyle. They resort to a portable shelter type, the black tent, that can be carried and assembled easily. This article introduces this shelter type applied in the Bakhtiari tribe, which has a his tory dating back to the Iranian civilization. This s tructure has retained its identity due to its ability to meet the needs of its inhabitants for centuries and remains a valuable legacy of Iranian architecture. The field s tudy of Bakhtiari tribes is run by assessing their spatial conditions and adapting them to the library s tudies. The uniqueness of this architecture is in its flexibility and compatibility with the environment. The harmony and rhythm used in interior decoration are directed by climate, culture, cus toms, and living conditions, thus forming temporary architecture. According to the given site, the natural material type consumed in this s tructure is feet, creating comfort in the inhabitants' lives. The seasonal and functional condition flexibly dictates the size and plan of the black tent. In this context, to preserve this heritage running in-depth s tudies on this issue is of the essence.

The famous “Shapur Cameo” from the collection of Bibliotheue Nationale is an important object and appears in various studies of Sasanian art, as well as of arms and armour. Studies focus on dating of the object, identification of the scene or identification of the depicted personages without asking the basic question whether the cameo is surely genuine. The conclusion of the article is that the arguments pointing to its nineteenth century origin prevail. It must be stated that the Sasanian elements are employed in very skilled manner both in terms of composition and majority of depicted details, however indecisive nature of the picture which does not clearly define the victor, unclear clothes or garb of the Persian figure, archaic sword of the Roman figure, his awkward position, and not tied tails of the horses, allow to believe that the person who designed the cameo was not fully aware of Sasanian realia. The Sasanian elements are gathered from the limited range of references. The separate argument is that cameos are not type of art favored in Sasanian Iran.
