The foundation of today's world is based on increasing productivity by using modern technologies and reducing costs. In road transport, the issue of promoting safety is one of the most important issues. Different approaches have been proposed to increase the safety of roads, each of which has advantages and disadvantages. The most effective options are the use of intelligent road transport systems to increase safety and reduce accidents. In this research, we have tried to compare the impact of the installation of intelligent systems and the correct location of the installation of these systems on road safety and reduction of road deaths by examining the objectives of ITS application and the impact of the installation of intelligent systems.This research, based on the descriptive-analytical method, has tried to evaluate the proper location of intelligent road transport equipment in the Shahrood-Sabzevar axis in Semnan province using the investigation and identification of strike sections. Using the analytical method, the status of existing systems Intelligent transportation has been evaluated according to technical criteria and criteria. Using the GIS location model, the location of installation of intelligent transportation systems in Shahrood has been taken. The analytical functions of multi-criteria model and need assessment of incident sections Identified by the province using ARC GIS software, GOOGLE EARTH, RMG and M AP SOURCE has been helped to select the optimal location for these systems. The results of the research show that in recent years, with the installation of intelligent road transport systems, the number of casualties in the outskirts of the province has decreased significantly. In total, the year 92, compared to the year 87, has a 37.6 percent reduction in casualties. This research, in addition to providing a template for the installation of intelligent systems in all parts of the province, can provide solutions for the optimal use of intelligent systems.

The purpose of this study is to investigate the relationship between migration and social capital of Semnan citizens and reviewing the related theoretical approaches. The aim of this study is to investigate the impact of migrants' entry on social capital. In addition, this process has been calculated based on the years of residence of citizens. Regarding the previous researches and controversies about the impact of immigrants on the migratory regions, this variable has been selected as a variable affecting the movement process of the community and determining the social indicators of the communities. The method of this research is survey and the statistical population of the citizens is urban planners. 150 of them were selected by multi-stage cluster sampling to complete the questionnaires. The results obtained by using different parametric and nonparametric tests indicate a direct relationship between immigration and social capital. It was also determined that the years of residence of citizens have a direct and strong relationship with the variable of social capital, and the more people in the host city will have a higher social capital. Finally, there are suggestions for increasing the social capital of citizens, especially immigrants

The research method in this article is descriptive-analytical. The results of this study show that the significant difference between statistical indicators of Semnan province and other provinces of the country, especially neighboring provinces, has created conditions that contradict and contradict in many of the issues. Planning for growth and development in the cities and villages of Semnan province is different from other provinces of the country and needs its own planning. In the field and statistical surveys, it is clear that in spite of neighboring provinces such as Tehran, Mazandaran and Khorasan Razavi, the cities and villages of Semnan province suffer from a shortage of population and many of their problems are being corrected by adding the population. With the assumption that we can plan in such a way that the province of Semnan becomes the cheapest province in terms of housing in the country. The extent of the Semnan province and its low population and climatic, dry and humid conditions in most parts of the province have led, unlike other provinces, most of the land to the state, and therefore planning to settle more population in the cities and villages of the province is very Simple and feasible.

This research is a research about the causes of youth tendency to use narcotics in this research. The statistical population of this study was a sample of 100 people and among the addicts who referred to the Coordination and Rehabilitation Headquarters of the Welfare Organization. In this study, six hypotheses were considered and examined, which ultimately confirmed all of our hypotheses. In other words, there is a significant relationship between the hypotheses and the causes of youth tendency towards narcotic drugs. The research method used to achieve the result is a survey method. However, we use two techniques, a library method, and a questionnaire for collecting information. In the present study, we tried to look at some of the transitional and superficial aspects of the definition of addiction, the characteristics of addiction addiction stages, the recognition of the personality of addicts, the history of drugs in the world and Iran, and .... At the end of the research, we also presented research suggestions, but in the future, the research constraints, such as those in the above research, would be eliminated.

Today, drug addiction is one of the biggest problems which most countries in the world are somehow involved with. The heroin crack has short and long term effects on emotion, cognition and behavior. The purpose of this study was to compare memory and attention performance in people between heroin cracks addict, opium addict and non-addict individuals.

The statistical population of present study consisted of heroin crack addict, opium addict and non-addict individuals. Two groups of addicts were selected among clients referred to addiction treatment clinics in Shahrood. Also, non-addict group, 30 individuals, without any history of drug use, were selected from the patient's attendants by purposeful sampling. The research tools consisted of Wechsler memory test and cognitive test set using the COG LAB software. Data were analyzed using Analysis of variance Multivariable Analyze of Covariance (MANCOVA).

There was a significant difference between the non-addict group and opium addict and heroin crack addict groups in the case of memory performance. Regarding the divided attention, the difference between non-addict group and opium addict and heroin crack addict groups is significant. Regarding the concentrated attention with high processing rate and low processing rate, there is a significant difference between non-addict group and opium addict and heroin crack addict groups.

The brain's prefrontal segment which is responsible for controlling and processing stimuli shows most injury by heroin crack abuse in duties, which requires rapid processing or delay processing for stimulus storage. It is suggested that researchers explore the pathological and physiological abuses by using advanced imaging and functional evaluation techniques in the future.
