Saffron is one of the most valuable crops on the planet and the most expensive agricultural and medicinal product globally; this plant has a special place among the industrial and export products of Iran. One of the challenges in the production of this plant is timely harvest from the ground as well as red stigmas (branches) separating from other parts of saffron because the flowers are harvested in a brief period. Further, harvesting and separating at a limited time is a critical point. This research has been tried with the help of image processing techniques to discuss and recognize saffron flowers and how to identify them on the ground. In the first step, saffron flowers are recognized by transforming colored spaces. Then, the histogram and the minimum threshold are used to segment and remove extra pixels. For this purpose, to identify flowers, RGB space is converted to YCbCr space, and the combination of HSI and YCbCr color space is used to distinguish other objects in the image; also, a histogram of Cb component for early identification of saffron flowers are used. Then, those pixels which are misidentified are removed by the threshold value. Next step, the saffron flower needle-shaped leaves that are placed on the flowers are restored by morphological operation of the proposed method, and the flowers that overlap are removed. Then, the type of saffron flower (bud, broken, open flower) is determined, and the ability of harvest or suitability of saffron flowers for harvesting has been determined. Finally, the flower center that can be harvested is recognized and used by the saffron harvesting robot. Average results with respect to the accuracy, recall, F-measure, correctness, and correlation coefficient were 99.79, 99.42, 99.60, 99.91, and 99.50 achieved by the proposed method, respectively.

Proper use of natural resources to improve living standards leads to growth and macro-sustainable development. Proper use of production resources and their proper recycling will play an important role in the growth and health of a society. One of the problems with the current environment due to population growth and development, trash talk and buried it. The potential use of waste due to the continuation of production is very high, but due to the slow recovery, many problems are buried. The location of landfill areas Birjand as a strategic area, is evaluated. In order to introduce the 4 main criteria for the analysis of two multi ANP and entropy method was used for the right place in the GIS environment. 4 standard natural environment, geological and hydrogeological conditions, economic factors and how to exploit the situation in the region as the main criteria were selected location. The four criteria considering the 15 sub-criteria model in GIS environment and ultimately ranked fifth convenient location with ANP and 4 using the appropriate method for entropy method was presented. In order to analyze the spatial distribution of the error of choice in the GIS environment were analyzed and based on the distance to the city were analyzed. Distribution of selected locations with two methods of entropy and ANP showed that the spatial distribution of more than ANP and Entropy two positions A4 and A5 are higher than other places Daria choice of the aquifer and the city of Birjand.

Social experience of human mainly forms with social network interactions. This study has been done with the aim to investigate the quality of students’ interactions in very private areas to more public domains. This is a survey with a descriptive-correlational method. The statistical population consists of 2600 Gonabad University students among which 340 were selected using Cochran’s sample size formula and multistage sampling method. The research instrument is a researcher-developed questionnaire that its validity was confirmed by experts. 92/5% of the respondents have evaluated favorable interactions with family members, 7/5% facultative and only 0/5% undesirable. Most utility of relations has been reported in the sphere of intimacy, respect and empathy, cooperation, consultation and lack of jealousy among the network of family relationships and especially mothers’ family and neighbors, and the lowest has been reported in relations with colleagues. D. Summers Test amount on correlation between educational level and quality of interaction was -0/446, which showed a significant inverse relationship between these two variables, at a significance level of P

In the past 25 years, natural disasters have taken lives of almost 3 million people and caused about $23 billion of damages worldwide. Iran is one of the 10 most disaster-prone countries in the world, and lack of preparedness of hospitals and healthcare centers burdens the healthcare system with $280 million each year. In this study, the research environment consisted of all hospitals of Birjand (Emam Reza, Valiasr, and Social Security Hospitals) and cases were collected via census method from our research environment. Data were collected by means of a standard checklist consisting of 220 questions in 6 sections of equipment, human resources, physical environment, structure, protocols, and performance chart. The tool was validated through content validity and face validity methods. Moreover, reliability which was estimated by the Kappa test was estimated as good (0.8). SPSS software was used for the analysis of checklist results. Descriptive analysis of data is presented through frequency, frequency percentage, and mean and standard deviation. In general, the level of preparedness in terms of communication with a value of 28.51% was considered as weak. The admission, transfer and discharge, traffic, security, and management training, respectively, with values of 58.26, 43.45, 52.77, 49.07, 44.17, and 56.11% were measured as medium. However, the emergency, support, and staffing with values of 67.36, 66.41, and 60.92% were rated as good. The lowest and highest values were that of the communication and emergency sections, respectively. Altogether, the hospitals’ preparedness, with a value of 52.27%, is at a moderate level.Discussion and Birjand hospitals are in need of improvement in the areas of communication, admission, transfer and discharge, traffic, safety, training, and management, and appropriate decisions need to be made with regard to this issue.
