The ability to recognize and compare shapes and understand the concept of proportions is one of the first human findings from environmental geometric data. And certainly the formation of geometry as a science of recognizing the arrangement of lines, shapes and levels and proportions leads to the definition of golden proportions in the mathematical sciences as a new way of organizing shapes and forms. Golden and geometric proportions are effective as a determining element in the scale of spatial forms, and the formation of spatial forms by not using or misuse of geometric proportions is due to functional and psychological interactions on human perception and cognition. Which causes the construction and formation of scales and proportions of the environment and the emergence of psychological effects due to human activities in the environment. And then the abnormal effects and environmental dysfunction on the saccade system of the human eye and as a result the feeling of fear and lack of belonging to the place interacts. On the other hand, nature as the raw material of creation, and the principle and mother of man, which causes him to model the proportions in nature. Understanding the laws governing the relationships between elements and spatial shapes leads to the formation of geometric and golden proportions in the spending of space. Because knowing the symbol of shapes, proportions and scales in the world of meaning and kingdom is reminiscent of the divine order in all dimensions of the world (even in astronomy). Therefore, evaluating the values ​​of spatial proportions in nature as the bedrock of human life and the pattern of psychological perceptions, leads to the adoption of human activities. Also, the study of human needs on a mental and psychological scale from the perception of the environment causes the recognition of scales and dimensions by human visual senses, which leads to the perception of the correct golden and geometric proportions through Sakadi eye movements and psychophysical sciences. . Certain ratios can also be observed in the creation and design of various shapes in nature. These relations are those geometric relations that have immaterial roots and follow the spiritual and supernatural principles, believing that their subject is sacred, and have a symbolic language and spiritual characteristics. In the traditional world, geometry was inseparable from the other four Pythagorean sciences, namely arithmetic, music, and astronomy. And traditional geometry is also associated with the symbolic composition and shapes of space. To this end, the study of the effect of golden and geometric proportions on human visual perception of the architectural environment based on the sense of belonging to the place, causes visual quality to increase the sensory richness of the place and achieve human values ​​and criteria in the sense of belonging to the place and human needs. To be considered by the architect. In this research, with the perspective of this identity and the interaction of geometric and golden proportions and the sense of belonging to the place, the criteria and indicators of the research have been studied and the results have been presented in the form of tables and diagrams.

Following Arab invasions into Iran and their territorial expansion within the Sasanian realm, Iranian discontent with Arab rulers grew, particularly during the Umayyad and Abbasid periods. These grievances sparked uprisings and revolts, eroding Arab control over the eastern reaches of the Islamic Empire and gradually enabling local governments in the east to assert autonomy. Amidst conflicts on its western borders and engagements with the Byzantine Empire, the Abbasid Caliphate grew uneasy as local governments like the Tahirids, Saffarids, and Samanids declared independence, albeit with nominal allegiance to Baghdad. Among these emerging powers, the Samanids of Transoxiana, centered in Bukhara, rose to prominence. Originally prominent commanders within the Abbasid army, the Samanid rulers, with the backing of their people and forces, navigated toward independence. Initially part of the Abbasid army hierarchy and beneficiaries of military training under the Abbasid regime, the Samanid emirs seized the opportunity created by the weakened Caliphate and conflicting interests with Baghdad, establishing a semi-independent government in the east. In this historical context, military forces and militarism held significant importance for all the established systems in the eastern regions, including the Samanids. The military played a pivotal role in shaping and sustaining Iranian local governments like the Samanids.

The artifact studied in this paper is a bimetallic sword made of bronze handle and an iron blade, which was excavated from the Tol ancient cemetery, located in Talash city, Gilan province, in 2001 by Mohammad Reza Khaltabari. This research aims to study the technology and pathology of the mentioned object by conducting comparative and archeological studies using the library method, conducting technological studies using the laboratory methods of radiography, metallography, and microstructural observations using a scanning electron microscope (SEM-EDS). The phase analysis of corrosion products was done by X-ray diffraction (XRD), as well as knowing the manufacturing method and identifying the types of damage and corrosion. The result shows that this work belongs to the Iron Age. Also, the tests performed on the two parts of the handle and the blade showed that the material of the iron blade is iron-carbon alloy. The amount of carbon in different parts of the body of blade is not the same and the handle is made of bronze alloy with casting and hammering techniques. It also has a galvanic corrosion effect.

The Scythian Empire is a controversial book with a charming title that can attract the attention of any scholar. Christopher I. Beckwith presents claims in this book that accepting each one of them leads us to rethink many previous customary historical beliefs. Some of his theories are novel but most of them are rehabilitation of older obsolete ideas. The book wraps a wide range of specialized topics in the fields of history, archeology, and linguistics; but deals with most of them on a superficial level. Since the Scythians were an Iranian ethnic group, this work is especially recommended for scholars of Iranian history, as unfortunately, the significance of the Scythians in shaping Iranian history has not been recognized as other ancient Iranians such as the Persians. In a broader sense, this work can be also useful for scholars interested in the Iranian world and its relations with neighboring civilizations, Eurasia, Central Asia, and China.   

The purpose of this study is to the development of creative industries through the development of cultural quarters within historical contexts as a creative strategy that affects the city as a whole and provides the field of competition and the possibility of being present at international levels. The research method is descriptive-analytical and its type is applied-developmental. The geographical area under study is "Karim Khan" street in Tehran, which has a rich historical and cultural identity. Therefore, using the hierarchical analysis process and "Lisrel" software, the cultural quarters' indicators were ranked and each one's importance was extracted. The findings, according to the calculations of the importance coefficient and the compatibility coefficient of each of the indicators in the study area, show that the "walkability" criterion, "the drivers of the creative economy", and the meaning index of a cultural quarter, the criterion of "evocativeness and urban memory" with importance coefficients of 0.62, 0.78, and 0.65 in the quarter have been assigned the highest rank among other indicators. And as a result, it was shown that the economic importance of sidewalks and the presence of active horizontal grains on the edges, the permeability of the passages, the safe accommodation for pedestrians, the facilities for the transportation of cars and their related services, as well as the quality of urban furniture and green spaces in the quarter as underlying factors. The instrument of creative development and the formation of the cultural quarters are the most important.

Biological samples such as bones, tooth, and hair obtained from archaeological excavations are mainly used for dating measurements. However, these findings provide valuable information about the diet, lifestyle or migration, and genetic interaction of communities, and disease because the biochemical content of biological tissues such as bones, teeth, and hair changes under the influence of the lifestyle of the past population. Therefore, it seems that human remains' biochemical, microscopic, and histological studies could be advantageous for clarifying the dark events of the past societies. Bioarchaeology, as an interdisciplinary science, assesses the historical-cultural relationships in ancient samples and human remains like hair, bone, or tooth by biological tools and techniques. In this science, the biological data of specimens are combined with archeological information to obtain a more accurate sociology of past civilizations. The purpose of the present review article is to familiarize archeology researchers with the usual methods in bioarchaeological studies.

A recent trend in photogrammetry is the use of unmanned aerial vehicles (UAVs) for photogrammetric purposes. A data acquisition sensor is mounted on an unmanned aerial vehicle to collect data during short-range aerial photogrammetry from a low altitude. This system is capable of filling a significant gap left by other conventional methods in the field of map production. The improvement in processes over conventional methods is the basis for this method's effectiveness. A significant portion of valuable data is obtained after the first processing stage as a result of automation in all data production processes. Real orthoimages, 3D models, and a detailed point cloud of the area are all included in this data. Drawing and mapping maps have gotten much easier, more accurate, and quicker thanks to modern software. We are looking for ways to use these kinds of methods in documenting the archaeological heritage in this article by applying this method at the historic site of Susa. The experts and practitioners in this field will benefit from this method, which is a collection of the most effective techniques for geometric measurement, analysis, and interpretations related to issues raised in archaeology.

Luristan is located in the Central Zagros Chains and it plays an important role in the events of the first millennium BC. Therefore, archeological and historical studies of this region lead to a better understanding of the events and the role of Lorestan in this period. The purpose of this research is to investigate the role of Lorestan in the first millennium BC based on historical and archeological sources. This research was done with a descriptive-analytical method with a historical approach. The Results show According to the Assyrian documents, Greek and Roman sources an ethnic group lived in the Zagros Mountains. Their land more probably was bigger than the administrative borders of Lruistan. Presumably, it should be somewhere between the Greater Media and Susa or Chaospes River. Luri is the common language of these peoples in this area.
