Iraq used chemical weapons in the war with Iran, in military and civilian areas. Due to the long-term effects of these weapons, Considering over 35 years after this eight-year war, the number of chemical warfare victims is increasing. This research aimed to investigate the spatial distribution of chemical warfare victims by province.
Instrument &

This descriptive-analytical research study was done using data obtained from the General Department of Statistics and Information Technology of the Martyr and Veteran Affairs Foundation. The data of chemical casualties includes the number; place of residence, gender, and type of injury in 2021 that were analyzed using SPSS 20 and ArcGIS software and Moran's test.

The total number of veterans in 2021 was 601330; 10.7% of them were chemical victims. Tehran (11%), Isfahan (9.67%), and Khorasan-Razavi (6.92%) provinces had the highest, and Hormozgan (0.39%), South-Khorasan (0.66%), and Sistan & Baluchistan (0.77% provinces) had the lowest. The spatial distribution of chemical warfare victims showed a cluster pattern.

The consequences of Iraq's use of chemical weapons can be seen in all of Iran’s provinces, and all provinces have chemical victims. Tehran, Isfahan, Khorasan Razavi, Kerman, West-Azerbaijan, and Khuzestan have more chemical victims than other provinces.

Due to the special economic and social situation of the rural environment, the rural elderly are at risk of reducing their quality of life compared to the urban elderly. This study aimed to investigate the quality of life and its determining factors among rural elderly in the southern counties of Fars province.
Instruments &

In this survey research, 825 people were selected by cluster sampling method among the elderly population of Lamard and Mehr cities in the south of Fars province in 2021. Data were collected using a questionnaire that measured the different dimensions of quality of life, as well as its determinants and then were analyzed by the step-by-step regression method.

Children and spouses were the most important sponsors of rural elderly. About 80% of the elderly felt lonely, and about three-quarters felt satisfied with their health. About 45% in physical health and mental psychological health, and about 48% in social-environmental status, have a high quality of life.

Feeling of loneliness and cost of living are two important factors in reducing the quality of life and health of rural elderly. Also, the financial support of children and the acquisition of housing plays an important role in increasing the quality of life of the rural elderly.

 Today, pension funds have a key role in providing living expenses and improving the level of social welfare of the elderly. This study aimed to investigate the status of insurance coverage and support for the elderly in the Iranian provinces using developmental indicators and investigate the level of providing insurance and pension for the elderly in the provinces based on the level of development in infrastructure and technical, economic, production, cultural and social dimensions. 

 The research method is a secondary analysis, which examines the status of insurance and supports pension coverage for the elderly in Iran and compares it with provincial development indicators in infrastructure and technical, economic and production, and cultural and social areas.

 Kohkiluyeh and Boyer-Ahmad Province ranked first in providing insurance coverage and pension support for the elderly. Kohkiluyeh and Boyer-Ahmad had 28th, 20th, and 8th ranks in development, infrastructure and technology, and economic and production indicators. Sistan-Baluchestan and Lorestan provinces had the second and thirsty ranks in insurance coverage and pension support for the elderly. The ranks of Sistan & Baluchestan in terms of infrastructure and technical, economic and production, and cultural and social indicators were 26, 26, and 9, respectively. The ranks of Lorestan in terms of infrastructure and technical, economic and production, and cultural and social indicators were 24, 19, and 30, respectively.

 There are many differences between the provinces of Iran in terms of pension coverage, insurance, and support according to development indicators. Lack of access to social services and support is an obstacle to economic and social development. The distribution of development resources in the provinces does not follow a unique pattern, and the provinces' situations are different. Therefore, development in the country's spatial structure cannot be expected to be uniform.

Software defined networks have attracted enormous attention because they simplify the process of setting up the     network. They have been able to leave behind in a short time, most of the technologies that were used in traditional networks by industrialists and researchers. The ease and efficiency are due to the separation of control and data planes from each other such that the control plane is a logically centralized controller and the data plane switches in as the flow table has been implemented. In these networks, network topology adjustment is done using a flow table that has special flow rules and network services, such as Qos, security and etc., which operate as programs on the network. Flow tables can be directly or indirectly changed by any of these services in the network. Although access to the table of current units simplifies network configurations, it could lead to anomalies between flow rules for separate modules. In addition to consuming too much switch memory, these anomalies can cause problems for network security and    applications. Fortunately, so far, some researches on the detection of anomalies in flow tables of software defined  networks has been done but this method is not only imposing a great deal of time and processing on the controller, in some cases only conflict resolution has been performed. In this paper we have shown how to speed up the detection algorithm and then tried to improve the speed of anomaly detection algorithm in the flow table of switches in the    software defined networks using different variables.
