Many epidemiological studies have found that people living in environments with more green space report better physical and mental health than those with less green space. However, the association between visits to green space and mental health has seldom been studied. The environment surrounding residences and its recreational and commuting opportunities are believed to affect human health and well-being. Urban green spaces hold great potential for promoting an active life style that allows urban residents to achieve important health benefits. The type of urban green space that is most effective to reach the signals is still unclear. The objective was to systematically review the literature examining the relationship between quantity and quality of green spaces in the living environment and three health outcomes: perceived general health, perceived mental health, and (all-cause) mortality. This paper focuses on urban green space as one important type of urban open space and its relevance for human well-being. The result of research show further research should focus on exploring relationships between more detailed character-is tics of green space and more specific health outcomes in different population subgroups and in different countries. Quality of urban living and residents’ way of life involves a complex interrelationship between a wide variety of physical environments and social opportunities. These, in turn, determine residents’ physical and psychological needs. Due to unhealthy lifestyle, health promotion has become a prime concern in Malaysia because of the increase in life threatening illnesses. A proper green space planning is needed so that it facilitates urban residents with spaces for recreation, social and leisure activities. Unfortunately, Malaysia has not yet achieved a satisfactory degree of green space design and development to facilitate residents with a healthy environment. There are few restrictions on accessing and having contact with the urban green space due to planning and design issues.

The aim of this study is to investigate the relationship between social capital among employees with their job performance in Tehran's Forensic Medicine Organization. The study population consisted of all the employees of Tehran's Forensic Medicine Organization in 2015 that based on available statistics are 120 employees that because of limited statistical population, sampling has not been done. To collect data, two instruments were used to measure including social capital questionnaire of Nahapiet and Ghoshal (1998), with average reliability coefficient of 93% and job performance questionnaire of Hersey and Goldsmith Achiu model with average reliability coefficient of 88%. Descriptive statistics were used to describe the data and to analyze and evaluate the research hypotheses; test of inferential statistics including univariate regression analysis was used. While confirming the research hypotheses, results showed: Structural, cognitive and communicative dimensions of social capital of employees have an increasing and positive impact on their job performance and this effect is statistically significant.

One of the significant dimensions of human’s social growth is his moral development. The human being not only is a rational and intellectual being, but also is a moral being. His morality has its origin in his sociability. The human being not only is self-centered and concerned about his own interests and well-being, but also is concerned about others’ interests and their judgment of his actions and behavior. In addition, emotional perception of moral and ethics is also concerned about the importance of emotion in a moral approach; therefore, when we, as human beings, draw a line between emotion and intellect, and consider them as totally unrelated, we are actually heading in the wrong path. The results of this study revealed that the main categories of moral action consist of: knowledge management, decision making, individual’s will, coherency of moral perception. In addition, the main theme which was derived is culture. The culture theme was the most important theme derived from this study. This study tried to investigate Blasi’s moral action theory in the context of Iran.

The present research aims to examine the relationship between diversity management and its effect on staffs’ affective commitment with study on mediation role of Transformational leadership and perceived justice in Qaen health network. In theoretical sector with integration of human resource management and performance theories and the theory of diversity and leadership, a theoretical model has been made. The main question of research is when the diversity management puts a positive effect on staffs’ affective commitment and why these two variables affect each other. The statistical population consists of all the staffs at the administrative sector in Qaen health network. After collecting data, the hypotheses were tested using the structural equation technique and software Smart PLS. the results from statistical analyses indicated that diversity management puts a positive effect on staffs’ affective commitment, but diversity management does not put a positive effect on perceived justice. Transformational leadership has a mediation role between diversity management and perceived justice. The perceived justice has a mediation role in effect of transformational leadership and staffs’ affective commitment. Further transformational leadership and perceived justice have a mediation role between the diversity management and affective commitment.

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.
