The revolution in the field of Fawa shows the necessity of continuous development and evaluation of information and communication systems. The purpose of this research is to provide evaluation models in information systems development methods. The sample of this research was 40 specialists in the development and implementation of information systems, who were selected by the purposeful sampling method. The research tool was made by the researcher’s questionnaire for which Cronbach’s alpha test showed acceptable validity and reliability. The collected data were analyzed along with statistical tests during experiments. The findings have shown that the necessary operations in the traditional method are: needs assessment, feasibility study, conceptual and logical design, deployment and implementation, maintenance, reporting and documentation, setting goals, determining performance indicators, cost-benefit analysis and detailed design. is the system. Prototyping methods include: system improvement and development, needs assessment, conceptual and logical design, programming, testing and evaluation, implementation and physical design. In the life cycle method, they are: design, requirements assessment, feasibility study, feasibility report, identification of user information requirements, conceptual and logical design, programming, evaluation and testing, deployment and implementation, delivery, maintenance and development of the system, report and It is documentation. In the organization-oriented method, they are: determining systems and subsystems, information requirements, managing resources and formulating an information strategy. In the object-oriented method, they are: examining the system’s information interaction, system modeling, identifying important events, change diagrams, modeling processes, and drawing data flow diagrams. As a result different organizations, situations and information systems require the use of different implementation methods, and designers and implementers must act towards the realization of the standard operational measures of each method

The sudden appearance of ISIS in Iraq in 2014 and the formation of a self-proclaimed government confronted the Islamic world and the Islamic Republic of Iran with a new approach of threats and realities of Salafist Takfiri thinking and exposed it to various security defense threats. The type of this research is practical and with the aim of measuring the possible future threats of Takfiri terrorist groups against the Islamic Republic of Iran in a qualitative way. Takfiri terrorists, what will be the possible threats of these groups against Iran in the future? The method of collecting required data and information is library, documentary and field; In this regard, relevant questionnaires have been designed and distributed among the statistical population of 30 people, and the research questions have been summarized and evaluated using descriptive and inferential statistical analysis methods. The findings of the research indicate that the activities of Takfiri terrorist groups as a threat in the field of defense and security of the Republic of Iran are still ongoing and it is possible to re-use their capacities against the Islamic Republic of Iran and challenge its national security. It is available in the surrounding environment. The threat has more risks for the important and marginal interests of the Islamic Republic of Iran, and the number of actors supporting Takfiri terrorist groups is also high, and the process of formation and development of these threats is predictable and gradual. This group has a consensus regarding goals and principles and in practice they are enemies of Iran.

Social networks have become one of the serious threats to the national security of countries in many political, security, economic, social and cultural dimensions, and identifying their effects is very important; Therefore, the current research aims to answer the question, “What is the effect of social networks on the national security of the Islamic Republic of Iran?” and providing a suitable conceptual model based on the foundation’s data theorizing method (qualitative analysis) and the above topic was analyzed in five axes of causal conditions, land conditions, intervening conditions, strategies (actions and reactions) and consequences. In this regard, first, the basics and related literature were collected through field observations and library documents, and all significant concepts were extracted and coded in the MAXQDA 1 software, and then, by combining and clustering similar codes., macro categories and influencing factors were calculated. In order to validate the above factors, the results were discussed and analyzed in focus groups consisting of professors and relevant experts, and 70 experts in this field were determined as a statistical sample, and by obtaining expert theories through a questionnaire tool (also interviews with 15 experts), their quantitative analysis was evaluated according to the “Chi test”, the level of significance and accuracy of the factors. In the following, by categorizing the factors in the five axes of causal conditions, land conditions, intervening conditions, strategies (actions and reactions) and consequences, a “conceptual model of the influence of social networks on the national security of the Islamic Republic of Iran” was drawn and presented. The results of the research showed that social networks have a significant impact on the national security of the Islamic Republic of Iran and its threatening process is also increasing and is moving towards weakening national security. This issue has been going on in all areas of national security, including cultural, social, political, economic and security, and the trend of people using social networks has increased the gap between the government and the society, reducing the supervision and control of the government over economic activities and affecting the lifestyle and It will be culture.

In recent years, the Islamic fundamentalism of ISIS and their actions had affected the Middle East region and the entire international system. In particular, the Islamic Republic of Iran was directly exposed to the threats of ISIS in terms of its Shia and non-Arab identity. Among these threats, we can mention the radicalization of the region through the gap between Shiites and Sunnis, the threat of borders, etc. But the destruction of ISIS in the region cannot

In recent years, the security stability of border areas has become a dynamic and multi-functional reality of the international and national policy system. In the meantime, stable and strategic security in order to improve the quality of life of border residents and the realization of balanced border development has an undeniable role; Therefore, the aim of this research is to explain sustainable security strategies in border urban areas with a focus on the border city of Khodaafrin. The present research method is descriptive analysis and the type of research is applied in nature. The data collection method is library and survey. The statistical population of the research includes experts, officials and border residents of Khodaafarin city. The size of the statistical sample based on the population of the city and according to the table of “Karjesi and Morgan” was determined equal to “250” people. The sampling method was in the form of a quota, and a simple random method was used within the quota. Data processing was done through structural equation model in SmartPls software. The results show that the path coefficients (based on t-statistics) were significant in all the variables, with the highest significance in geographical, social, political, economic, environmental, institutional and military variables with coefficients of 4.430, 3.580, 3/326, 2/360, 2/185, 2/045. In general, the perception of sustainable security and its strategies in Khodaafarin city is significantly tied to the issue of “geography”, “economy” and “politics” and coincides with the characteristics of the mentioned categories; As the coefficient of importance of geographical, economic and political indicators was calculated as “0.368”, “0.461” and “0.364”.

Understanding and analyzing the human mind and behavior provides valuable data to discover criminals and free innocent people. The cognitive activity related to deception can be evaluated by the semantic reaction time measurement method, as a behavioral component of cognitive activity. The purpose of this research was to determine the difference in semantic reaction time in people with and without deception (lying) and this issue was investigated whether it is possible to use a precise tool to measure the response time of people to specific questions about truth concluded their answers. In this research, this time was measured using the semantic reaction time measurement task, which is a computer program. According to its goals, this research was of fundamental-applied type, and in terms of data collection method, it was semi-experimental with repeated measurements. The research sample was 28 people who willingly participated in this project in 2019. The research variables include the situational independent variable with two situations: 1) deception; 2) No cheating. The dependent variable was semantic reaction time and the control variables were male gender, age over twenty years, high school diploma and right-handedness. In this research, the exact delay time in answering the questions was calculated with the accuracy of one thousandth of a second, and based on the results, the hypothesis of the research was that the semantic reaction time in deceptive (false) answers to questions is longer than non-deceptive (true) answers. It was confirmed with a significance level of 0.001.
