Security has always been one of the most basic needs of human and improves social interactions, personal and social peace, prosperity of the people and thus caused the improvement of society. Modern urban spaces admitting to crimes and aberrations resulting in lack of security in the city, Security Survey in urban areas is an important issue. This paper examined the impact of residents' sense of safety in urban areas. It uses applied research and descriptive analysis. Quantitative methods and techniques used for evaluating data from the survey (see questionnaire). It studied two areas of Arak city: Hepco (Zone 1) and Ayatollah Saeedi (zone 4) .Research findings suggest that environmental differences are effective on the level of security in the city. People who live in zone1 feel more security than residents of zone 4 at night. Also the women feel more insecurity than men at night. Also between 4 studied subjects (men and women of both areas) men and women of zone 4 use other places for shop and fun more than men and women of zone 1. Also in both areas women use other places more than men .both groups have same ideas about the safe and unsafe places. The majority of them evaluate silent streets, one-way streets and low traffic areas as insecure places. In addition, people considered the presence of police and security forces, promoting the cultural and pay more attention to city design as an important factor of creating the sense of security.

With increasing frequency, the developing countries and the people living there are being affected by disasters. More and more often, development efforts are being destroyed. The reason for this trend is their growing vulnerability, which in turn is the result of economic and social development processes, such as the expansion of settlements and agricultural land in risk areas. The economic and social consequences of these disasters for the people in our partner countries last for years. To break and, if possible, reverse this trend, international organizations, governments and NGOs in the developing countries are increasingly upgrading the priority of disaster risk management for policy, and taking concrete preventive measures to reduce the risk to the population. This paper examined the concept of disaster and its management in the light of sustainable development with particular reference to Iran. It enumerated the different human and natural phenomena that could be characterized as disasters. It was discovered that, while hazard and/ or disasters possess anthropogenic origins, their consequences are felt on both human and the physical environments. In all cases, the human tolls have been significant. The paper highlighted the important elements of a typical Disaster Management Information System in Iran. After presenting a typology of disasters in Iran, the paper, advocated for a workable disaster management information system.

Following the creation of economic, social and environmental issues in metropolises, strategies aimed to build new cities to decentralize, attract the overflow of crowed population and reduce its activity, in order to enhance the quality of life and to organize the population and activity in urban areas. In the present study, the role of spatial planning for new towns in the metropolitan suburbs of Mashhad or in other words, the role of these new towns on the space balance, creating the employment and self-sufficiency and to absorb some part of Mashhad’s population has been studied. In this regard, in addition to the library studies and comparisons of existing status with the predicted targets for studying new cities, two series of questions regarding the condition of every new town, as well as analysis network process (ANP) were used to assess their success and to rank them. Results showed that the infrastructure’s indicator plays the greatest role in the success or failure of these cities in achieving their goals, so if the government does not provide the platform and infrastructure, new towns policy does not help resolve the crisis of metropolitans. After infrastructure, employment, attraction of people and accessibility have almost equally important and are in secondary importance. Eventually, our results revealed that Gulbahar has been more successful than Binalud, According to the results of the present study, the coordinated and proper management at national and regional levels, especially in the Mashhad conurbation, creation of employment opportunities, improving the identify and the quality of new towns and provide appropriate services is necessary and essential to citizens.

Today, there is a growing trend towards qualitative research in different areas of academic investigations. However, students face difficulties in deciding on qualitative methods of research, because most of the literature on qualitative research focuses on the philosophical and theoretical aspects, and they hardly offer any practical guidelines. This problem is rooted in the essence of qualitative research, which makes the details of the research process unachievable at the beginning. As a result, the features of the sampling plan—like the accurate size and form of the sampling—remain uncertain until after the data has been gathered, and this makes the jury doubtful about the approval of the research proposal. Hence, framing an appropriate and assayable plan for sampling can be of great help in the approval and execution of qualitative research plans. From this perspective, the present article aims to design a framework for a sampling plan in qualitative researches using theoretical sources of the grounded theory method and researchers’ suggestions based on practical involvement, as well as the recent experience of the authors in grounded theory research. By studying these sources, and considering the feedback for and practical involvement in the grounded theory method, a two-stage plan of sampling is proposed. The initial stage aims to ensure adequate diversity for the appropriate distribution of the samples, and the second, as a theoretical sampling stage, guarantees the theoretical attribute of sampling in qualitative research.

HSE management involves managing, controlling and handling all aspects of health, safety and the environment in the petroleum industry with the focus on major accident risk. In the field of residential and building construction ventures the workings met lots of practical hitches like procedure, responsibility, monitoring, evaluation housekeeping at Construction Sites and associated offices, perimeter area, stores, workshops, batching plant, stock yards and labor camp etc. it describes requirement of housekeeping activity at different stages of work & periodicity to maintain site neat & tidy, which should be budgeted, planned & adhered. Before commencing this activity site execution team is recommended to evaluate the foreseeable risk by conducting risk assessment of the particular activity so as to prevent any harm to the engaged team. So we emphasis to resolve this practical hitches by safeguard methods in venture works has been undertaking. We also focused is to address the safe work practices for different activities in construction work, considering its practical and engineering aspects and its implementation at site level under the responsibility of Project Head. Our study is being used for implementation HSE at site. We specifies the topic such as to fill a knowledge gap on site safety issues, to provide handy reference of best practices for frontline management teams, to offer site safety management techniques and tools for use, by practicing these documents effectively, prevention of incidents. This process of technique will help to ensure housekeeping standards and a safe & healthy work environment at all time.

Passive Defense is a set of civilian efforts performed to enhance deterrence, reduce vulnerability, sustain essential activities, promote national stability, and facilitate crisis management against military threats of an enemy. Since in battles, sensitive and critical areas of cities are of paramount importance,it is clear that in military agressions, a large part of threats are focused on cities and their urban facilities and equipment, especially fuel centers. As a result, consideration of passive defense while planning cities has a significant role in reducing the vulnerability of cities and their urban elements as well as facilitating the urban crisis management. It also provides the citizens resistance threshold under possible enemy invasion and natural malicious agents. Hence, this article reviews and analyzes the current situation of gas distribution centers and evaluates their positioning across the city of Mashhad with regard to passive defense approach. However, as far as there is no clear- cut criteria for organizing fuel centers with passive defense approach, the Delphi method is used to select the desired criteria in which on the basis of the final comments of the experts, four critera- performance, access, hazards and security election and spatial organization of the fuel tanks and petrol stations- are analyzed using AHP model and GIS spatial analyzes. Accordingly, it can be said that the assessment of the current status of the urban fuel stations in Mashhad indicates that no area of the city enjoys all measures of passive defense (performance, availability, security, and risks). Likewise, the results indicate that the distribution of these centers in the city are mostly consistent with the factor of access. taking into account all the criteria, it is the ​​North West of Mashhad which has the highest utility than other areas. It is followed by the east of Mashhad and ​​the Northeast and the middle east of the city, respectively. Accordingly, it could be stated that ignoring an efficient design for determining the optimum location of the site construction with a passive defense approach results in an inappropriate and naive spatial distribution of the stations leading to an increased security and environmental risks of the city.
