Crime is a social phenomenon that cultural, social, economicand evenenvironmental factors are effectiveonthe incidence of it. So better understanding and explanation of crime and criminal behavior in society is essential in connection with these factors. One of the most important issues in crime analyses is crime site. But as regard that geographicall ocation in relation with economic, socialand cultural inequality are effective in the incident of specific crime in those area, so disharmonyand spatial inconsistency in population structure can be effective in urban insecurity and formation of stability and security indifferent urban areas. In this paper spatial analysis of influence ofpopulationstructureon theincidence ofcrime in the urban regions of Mashhad metropolis as a second largest metropolis in the country. has been regarded The research method used, is descriptive-analyze and in order to analyzing the population structure indicators in three population, cultural-social and economic groups and the condition of spatial distribution of offenders with 6 types of crime has been analyze. Also in order to analyze the relationship between the variables with using SPSS software, related statistical tests is done and to display the spatial distribution of offenders and the rate of population spatial equilibrium at the urban regions has been used of GIS software. The research results indicates a significant correlation between population structure and being prone to crimeof the regions.

In the process of making urban environment suitable, it is necessary to create spaces that have been adapted to today’s needs, as well as having requisite elements of executing security and being organized to adjust with modern technology. Recently valuable attention has been paid to the security in our country as it’s practical consequences is to be gradually perceived, but no decision has been made to respond whole of the field security. This study was done with the purpose of studying urban neighborhoods security improvement in the north Janat Abad neighborhood in Tehran. The aim of this research is to identify the effective factors on the security of the people living in north Janat Abad neighborhood. From this base, the degree of security with creation of experimental model of security assessment (value tree) and surveying in 3 levels of functional, physical and social aspects is evaluated. Using questionnaire technique for collected data of 314 statistical samples we also used SPSS software for analysis of the data. According to the results, the variables relationship with "amount of security in north Janat Abad neighborhood" in 3 levels "functional", "physical", "social" have been proved. Between variables, identity of the neighborhood was the most effective factor on the degree of security of the area under study

Security means being safe from harm, anxiety, worry and fears. Security can be defined as be away from things that threaten financial interests (life, property, land) and moral values (religion, culture, beliefs). Because many factors can destroy peoples’ safety, it is important to know how people feel about security in different environments. This question is also imply in recreational and resorts areas, because security is an important factor which influence the use and prospers of these areas. The present article delivers the findings of a study which aimed to investigate the sense of security among tourists of forest parks in Golestan province. In this regard, the relationship between tourists’ behavior and their demographic characteristics are analyzed. The survey research was used and a stratified random sample of 300 tourists was studied. Results showed that the sense of security in the parks can be assessed as high. Also, sense of security are related to gender, level of cleanness of forest parks, noise level at forest parks as well as satisfaction of forest parks. Based on results, some practical recommendations have been provided to improve security in forest parks.

One of the basic human needs for the life of the security, much of it Shape of security in residential spaces. The researchers believe that factors such as social, economic, cultural, etc. are effective in creating a sense of security, among which we can mention the physical effects can be mentioned. The purpose of this study was to investigate physical factors affecting the sense of security of villagers in rural settlements on Binaloud County, using the approach "Crime Prevention through Environmental Design" or CPTED. This study is an applied one conducted in a descriptive-analytical method. In order to evaluate the factors affecting physical security, the opinions of 16 experts to estimate the level of physical security feeling the villagers, residents of 8 villages were questioning Binalud County, that of rural households in 5766, the sample size of 190 households were selected method stratified random sampling. In this study, using fuzzy hierarchical analysis were determined impact factors 9 index affecting the safety of the physical environment villagers and it was determined that quality passages factor with 24.3 percent had the greatest impact on the safety of the physical environment. Then, based on rank correlation analysis model GRA, rural settlements were ranked in terms of emotions and physical security, the results showed that the Virani village have been conditions better than other sample villages and has been ranked first in terms of the sense of physical security, and Sarasiab village is at the lowest level of physical security is felt. One sample T-test results showed unsuitable conditions are indicators of quality of streets and visual proportions in selected villages, and Suitable conditions indices vegetation cover and informal monitoring to increase the sense of physical security.

 At the same time as entering the third millennium and with increasing population, in many countries demand for water in order to supply dem world population needs has increased considerably. But because of scarcity of water resources and water crisis in intire world the concept of water security and water poverty persresented into the economic literature of countries wich facing water crisis. Water poverty is one of the greatest challenges of this century and the multidimensional crisis of the next incoming decades in the world, especially in countries with low lelvel of water resources. This crisis can lead to many changes in the world. In this paper, unlike the usual methods op other lasr aricles to calculate water poverty, we calculate the water poverty index is on the base of Catastrophe theory multi-criteria evaluation system and mathematical fuzzy logic method. The sub-indices  wich used to calculate the water poverty are including: water resources (water deficit ratio, surface water supply ratio, the proportion of other factors in water supply), access to water (per capita water resources, price elasticity of water demand, Gini coefficient for domestic use), capacity of Underground aquifers (groundwater utilization rates, surface water utilization rates, dilution rates), using of water resources (per capita consumption of water for irrigation in the agricultural sector, per capita consumption of drinking water, per capita consumption of water in Industrial sector) and environmental integrity (surface water drying, desertification rate, create desert rate). The results of calculating the water poverty index during the period from 1989 to 2015 indicate the upward trend of this indicator and its subset components, which indicates the worsening of the state of water security in Iran in recent years and possibly the deterioration and continuation of this complicated situation for next decades. In the other hand, as the current trend continues, both in terms of resources and in terms of managing the production and consumption of the country's water resources, Iran is gradually losing its ground and becoming poorer in terms of water resources.
