Background: Among various emergency services, the air emergency due to access to the extreme areas, possibility to move more patients, providing higher quality treatment to the patient being carried and also access to the hospital without problems such as traffic and sudden crashes, is one of the most important types of emergencies in the health sector. So, the right location according to the scientific principles, enhances the efficiency of the aerial emergency.
Materials and Methods: This descriptive- analytical present study was conducted as an applied research in Sistan and Baluchestan province in 2016. At first, indicators affecting the location of ambulances were identified. Then, the location using deploying a Fuzzy network analysis process model next to the Fuzzy Dematel technique and the integration with geographic information system was performed.
Results: Criteria for selecting the best places for deploying air ambulances in Sistan and Baluchestan province are considered as proximity to the roads, appropriate tilt area, proximity to crowded areas, proximity to high risk passages, and the convenient distance from the medical emergencies. Output weights of the technique used for affecting on GIS software were calculated 0.244, 0.083, 0.435, 0.182 and 0.057, respectively.
Conclusion: Study results revealed that number and coverage of aerial ambulances in cities and roads of Sistan and Baluchestan province are not suitable. Therefore, the map derived from the Fuzzy integration of the information layers identified by the effective factors, illustrated that the districts of Zabol and Iranshahr cities have the best status of selected criteria to establish the air emergencies bases in the province of Sistan and Baluchestan.

Field of study and Goals: The provision of medical services and the distribution of agonist drugs in substance abuse treatment centers has led to a lack of attention to patients' treatment plans and a greater focus on drug distribution. In order to separate health and pharmaceutical services that are provided for opioid addicts in drug addiction treatment centers, a study has been designed with the aim of locating the selected pharmacy for the distribution of agonist drugs in District 21 of Tehran Municipality with a spatial approach.
Materials and Methods: This applied research is a descriptive-analytical method. The spatial and descriptive data were collected from the municipality organization and treatment and food and medicine departments of Iran University of Medical Sciences and Health Services and they were analyzed using ArcGIS software. Distribution of pharmacies and drug addiction treatment centers in the study area, locating the appropriate areas, and locating the selected pharmacy were studied by using the kernel density estimation functions, hierarchical analysis, and location model - allocation in two regional and district modes with maximum coverage of drug addiction treatment centers, respectively and analyzed using SPSS software and t-test. 
Results: This study shows that the distribution of pharmacies and population in different regions of the study area is commensurate. Based on the results of locating using hierarchical analysis method, all pharmacies in the study area are appropriate to be the pharmacy for distributing the agonist drugs, and the results of the location model – allocation shows that the average time, and distance to access to the selected district pharmacy is 17 minutes and 5.9 km, respectively and for the regional pharmacy is 2 minutes and 0.7 km, respectively. 
Conclusion: Separation of medical services and distribution of agonist drugs is essential. The findings of this study indicate that the distribution of agonist drugs through selected regional pharmacies increases access to medicine and the satisfaction of patients.
