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.

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.

During a very long period of time, civil engineers have been the only ones to be designated as the experts for underground space, while the planners and architects were the ones of the development at the surface. Cities worldwide tend to overlook an invaluable asset that lies beneath their surfaces. Most cities and urban regions are unaware of the benefits underground space use has to offer, both for climate inflicted and spatial constraints: In many cities, infrastructure development is being outpaced by population Growth. Climate change effects are requiring radical new approaches in terms of coping with for example excessive rainfall. The available space at the surface is rapidly being used up and the biggest danger is that built-up spaces are taking over the public green spaces of cities thereby threatening livability and quality of life. Urban underground space forms a societal asset, which is often unappreciated and underestimated in terms of the role it can play within dynamic city environments and associated challenges. The world-wide trend of increased urbanization creates problems for expanding and newly-developing cities alike. Population increase leads to an increased demand for reliable infrastructure, nowadays combined with a need for increased energy efficiency and a higher environmental awareness of the public. The use of underground space can help cities meet these increased demands while remaining compact, or find the space needed to include new functions in an existing city landscape. Use of Urban Underground Space (UUS) has been growing significantly in the world’s biggest and wealthiest cities. UUS has been long acknowledged to be important to the urban development agenda: sustainability, resilience, livability, and creating a better urban environment in particular.

Like other economic markets, housing market is comprised of supply and demand dimensions and equality of supply and demand makes the housing market balanced. The aim of this paper is to investigate the characteristics of housing market of Tehran city and some deficiencies of this market with fundamental – applied methodology. The variable studied here is the saleable residential unit with minimum 50m2 area which is obtained after statistical evaluations of housing price for many years and estimation of the loans and deposit of families in different income levels. Results reveal that problems of housing market can be attributed to lack of appropriate planning in housing building and supply (in quantity, area and geographic location), decreasing purchasing power of people various income levels as a result of misfit of increase in income and price of housing, low demand of families and finally, limited income groups for purchasing appropriate housing.

The intention of this paper is to define the concept of the spirit of place, and then to identify methods for its preservation in historical urban contexts. In fact, this study seeks to answer the question whether the spirit of the place and its components can be derived from tissue structure to improve? And whether we can weave his old identity in psychological indicators - human behavior found? Finally, the aim of this methodology is to help researchers make an objective analysis and evaluation related with the very delicate subject; the spirit of the place and its comprehensible meanings from tangible features to intangible ones. The study hypothesis claims that the psychological component concepts, behavioral and moral spirit of the place can be viable tissue residential neighborhoods. This claim qualitative research design and analysis of research by using descriptive derived from Kerman al-Ghadeer neighborhood residents use the results of the survey population. And the spirit of the place and identity of contingency tables between two components in the sample studied is proof space.
