  • Determining the best interchange for Saturated Intersection with traffic lights (Case Study: Dizel Abad Intersection, Kermanshah, Iran)

    One of the main problems of metropolitan cities in traffic topics is the Intersection with traffic light. One of the weaknesses of these intersections is the creation of long queues due to left-turn movements during the peak hours of daily traffic, which reduces speed. The flow of traffic as well as the level of service decline. Therefore, optimizing cross-sectional intersections in order to reduce the delay time and production of pollutants and fuel consumption is of great importance. The purpose of this study is to examine and compare the results of converting a level crossing (case study of Dizel Abad intersection of Kermanshah, Iran) to an interchange using the Aimsun software simulator. The scenarios used in this study include the present status of the intersection of the study, Cloverleaf Interchange, semi-directional interchange, U-turn Interchange and U-Turn Interchange with a specific right-turn path, the final results show that the best interchange among considered interchange will be semi-directional interchange so this interchange will reduce around 81% in travel time and 68% in travel speed. Keywords. Intersection with traffic light, Interchange, Simulation.

This study had an applied-development type and its target data was collected from Statistical Centre of Iran and Statistical Yearbooks. Factor analysis was performed as research method; and obtained results indicated significant differences in environmental indices of sustainable development in metropolises of Iran. According to results, Ahvaz, Shiraz and Urmia had highest levels of sustainable development. Keywords. Environmental indices, Sustainable development, Metropolises of Iran

  • Analysis of assessment criteria in land-use planning with an emphasis on healthcare spaces (the case study of the City of Zabol)

    Healthcare services in urban areas is directly related with progress of urban communities. These centers will play a crucial role in the process of sustainable urban development by providing services to the people. So, quantitative and qualitative assessment of healthcare services in different dimensions is essential in sustainable urban development. In this direction, setting priorities based on scientific methods can be used in solving the problems of health care services and it will have a significant role in sustainable urban development by this approach. Hence, the goal of this research is analysis of assessment criteria in land-use planning with an emphasis on healthcare spaces (the case study of the city of Zabol). For this purpose, the present situation of healthcare centers in terms of compliance with the mentioned criteria is assessed. By compatible, desirability, capacity and dependence matrixes. The research method is descriptive-analytic based on documentary and library studies and field studies. The results show that Imam Khomeini Hospital in the majority of matrixes (the adaptation, Desirability, capacity matrixes) is placed in the first rank. Keywords. Land Use, Healthcare Services, the city of Zabol, sustainable development.

La tecnología de la información tiene un impacto significativo en los procesos sociales. Esto lleva a las relaciones sociales. En el último tiempo, muchos países, incluida Rusia, incluyen su tarea, la transición a formas electrónicas de gestión, que son necesarias en la sociedad de la información. La creación de los desarrollos más recientes en el campo de las tecnologías de la información es la dirección estratégica más importante de la política estatal. El estado actual de la ley y la ley están en una interconexión difícil y poco clara con los procesos de modernización en el país. Problemas de interrelación de cultura legal y tecnologías de la información. Palabras clave: Tecnologías de la información, Internet, conciencia legal, cultura legal.

  • Active and interactive methods in the contemporary education

    En el proceso educativo, un profesor siempre está buscando formas de transferencia de conocimiento, lo que permite a los estudiantes comprenderlas de manera exhaustiva y permanente. Hoy se reconocen las formas pasivas, activas e interactivas de interacción entre el profesor y el alumno. La forma pasiva de transferencia de conocimiento es la más básica, cuando un conferenciante es la única persona que administra el proceso educativo. Esta es la forma de las conferencias clásicas, cuando el conferenciante se comunica con la audiencia sin interacción con los estudiantes sobre el tema específico. El uso de la forma pasiva es posible durante los seminarios prácticos, cuando el profesor realiza la encuesta de prueba de los estudiantes, realiza pruebas individuales. La forma pasiva es criticada como ineficaz. Se cree que el método interactivo de comunicación entre el docente y los alumnos es un tipo de método activo. Pero, en los últimos tiempos, debido a la aparición de una variedad de métodos interactivos, el método interactivo se identifica como uno independiente. La capacitación interactiva desarrolla habilidades analíticas y creativas de las personas, promueve la digestión óptima de nueva información y la retención de edad. Al usar métodos interactivos, todos los estudiantes deben participar en el proceso educativo, aportando su contribución individual. Al final del seminario, los estudiantes deben recibir orientación e información para su consideración. Cada estudiante debe darse cuenta de lo que ha aprendido, qué habilidades se han formado. Palabras clave: desarrollo social, estudiante, educación, docente, comunicación.

  • Ecosystem approach to the legal regulation of digital economy

    This article discusses several aspects of Digital Economy. Firstly, the term «ecosystem» is analyzed according to the concept of «ecology». Secondly, ecosystem approach is viewed as the concept that describes the evolution of the nature of interactions of economic agents, models of their innovation activity and their relationship with the environment of functioning. Thirdly, current issues for Digital Economy are identified. The paper concludes that ecosystem approach considers innovative systems of all levels (national, regional, cluster, etc.) as living social organism subjects. The ecosystem approach puts forward a number of important economic principles: firstly, the ecosystem has its own, market mechanisms of self-development; secondly, it focuses mostly on the nature and dynamics of interactions (with each other and with potential participants), emphasizing that it is the collaboration that creates and diffuses the flow of knowledge, the transformation of these flows into innovation and further spread of innovations throughout the economy. We emphasize the role of openness for uniting the efforts of the community interested in the development of a digital industry, extension of public-private partnerships and building a competitive environment in order to ensure the rapid growth of available digital services, as well as to improve their quality. The emergence of the issue of digital economy has introduced a new driving force to the transformation of international society. The principles of ecosystem management and the principles of the ecosystem approach should underpin any decisions taken at the universal, regional and national levels. Keywords: digital economy; ecosystem; digital ecosystem; transformation of society, ecosystem approach, ecosystem management, International Economy Law.

  • Review of emergency structures in competitive games

    One of the biggest problems of human society is facing crises. Origins of many crises go back to strategy selection in the relations between human beings. In this article, the crises have been discussed, whose origin is relations between human beings. By defining critical points in 2 × 2 games, we provide a mathematical model to detect this type of crises, and then by defining a unique compromise point, we offer solutions for this type of crisis. In many crises such as The Cuban Missile Crisis, Nash equilibrium will not work and leads to the creation of a vacuum in the use of game theory. We believe that what is presented in this article can help fill the void. Fixing the vacuum in game theory and optimal use of compromise and critical points leads to the development of cooperation - cooperation strategy in the world.
