Introduction: In the contemporary era, suicide rates have markedly increased in society by increasing the population, expanding the industry and machine life, and the prevalence of the various types of mental and emotional problems. Establishing suicide prevention centers is one way to reduce suicide. In order to improve disorders, these centers provide long-term clinical, rehabilitation services and support programs to people affected by the disorders. These services are aimed at preventing the re-recurrence of the disorder and their complete recovery. In addition, creating an appropriate environment based on the therapeutic architecture can be of great importance for the improvement in the patients admitted to these centers. For this reason, color as a visual architectural element can affect individuals' mental and emotional states. In this regard, the present study investigates the effects of color on the emotional states of suicidal patients admitted to these centers.
Methodology: The present study is descriptive-analytical, and a significant part of the paper was based on the documentary method, and library studies were a data collection tool. In the research, the space modeling research method was used. To this end, a room model was modeled as a sample in the space of 3DMax 2014. The subjects were placed in a virtual environment and answered the PAD emotional questionnaire regarding the color of the interior space of the rooms, using Samsung Gear VR virtual reality glasses. Causes and factors affecting suicide in Iran were also investigated. The principles and foundations considered in designing these buildings were extracted by referring to written sources, scientific papers, and research related to suicide. SPSS software and Pearson correlation research method were used to analyze the data and measure the relationship between variables and analyze the results.
Results: Pink is considered an unpleasant color that affects and surprises them. These subjects feel scared in such a room. White is one of the colors that make suicidal people feel calm and sleepy in such a space. These subjects are aroused and upset in red-orange rooms. This color makes the subjects nervous, which increases their aggression and cruelty.
Conclusion: Among the five colors of white, red light, turquoise blue, pink, and red-orange in two states of pleasure and arousal, there was a significant relationship with the tendency of suicidal people. The results obtained from the study show that suicidal people, among the different colors, considered the rooms with turquoise blue and light red as pleasant colors.

Introduction: 
Enclosed housing estates are limited-access residential areas that have recently expanded around the world. These complexes are designed to achieve the highest quality of private services and escape from urban disorder. Measuring the sense of the place could be a criterion for the successfulness of an urban or architectural complex. The sense of belonging will indicate the efficiency of the architectural and urban design. So far, these components in spaces regarding job or occupation have not been studied, and the research structure without intervening the variable was considered the purpose of the project construction. The purpose was to find the factors affecting the creation of the sense of the place in a closed urban complex. The case study was the National Iranian South Oil Company town.
Methodology: 
The research was a quantitative and correlational survey. The information was collected by distributing the questionnaires among the residents over 18 years old randomly. The questionnaire was based on the Likert Scale, and the sample size was determined 362 based on Cochran’s formula. The statistical analysis was conducted using SPSS software and utilizing Spearman’s correlation coefficient to assess the research model and evaluate its validity, and Friedman’s test was used to prioritize the variables.
Results:
indicate that there is a significant correlation between physical architecture (public and private), activities and social interactions, and hyper architecture. The percentage weight of Friedman’s test of the main components were as follows: private physique with 31.12%, indicating the maximum effect on the sense of the place, public physique with 25.50%, hyper architecture with 24.30%, and social interactions and activity with 19.10%, respectively.
Conclusion: 
Show that there is a significant correlation between physical architecture (public and private), activities and social interactions, and hyper architecture. The percentage weight of Friedman’s test of the main components were as follows: private physique with 31.12%, indicating the maximum effect on the sense of the place, public physique with 25.50%, hyper architecture with 24.30%, and social interactions and activity with 19.10%, respectively. The results of Friedman’s ranking test of the sub-components showed that cleanness and hygiene, religious association, and access to urban transportation have the highest average rank. These sub-components are the most significant and influential factors on the sense of the place in the oil company. Organization and quality of the interior spaces, social interactions and participation, and access to the town services ranked next. The sub-components, sense of security in the town, and residence duration of the residents have the minimum impact on the sense of the place.
