Results of Ballou's study (2007) also showed that the satisfied employees work with favorites in work environment and are loyal to organization and help to increase the efficiency and capital in organization (Ballou, Norman, & Goodwin, 2007). Results of other studies in Columbia also showed that the faculty's knowledge of work life has strong and direct impact on satisfaction or incentive to withdraw from the university (Dolan et al., 2008).
This relationship also has been reported in studies which were done in Iran (Mirkamali & Narenji Sani, 2008;Teymouri, 2008). In study by Soltanzadeh (2012), components such as constitutionalism in organization, social relevance of work life, social integration were the best predictors of job satisfaction in faculty members (Soltanzadeh, Ghalvandy, & Fatahy, 2012).
In universities in Iran, formal employment and job security changed to stressful issues because of some factors such as the long process of faculty recruitment, scholarships allocation, stated the need. Workload and teaching hours of faculty also hinder some activities in other areas such as research and service (Noor Shahi & Samie, 2011). Many studies have been done in other countries about job satisfaction of faculty members.
But, the conducted studies about quality of work life in Iran are less and limit, thus it is necessary that the more and comprehensive research conduct in this topic. It is very important especially when the increase of quality of work life and its relationship with job satisfaction is propounded.
No study has been done concerning of quality of work life and job satisfaction in faculty members in Zahedan University of medical sciences. Moreover; according to importance of these two variables for advancing the academic goals and creating more efficiency and also some situations in Sistan & Baluchestan province in Iran such as shortage of amenities, this study conducted aimed to determine the relationship between quality of work life and job satisfaction in faculty members.

Method
In this descriptive-analytical study, all of the faculty members who were 202 people and were employed in Zahedan University of medical sciences in 2012 entered to study through census. The contract, committed to serving and tuition teachers were excluded from the study. Data were gathered through information form (age, gender, marital status, work experience, academic degree and employment status) and the Walton quality of work life questionnaire (Walton, 1973) and Job Descriptive Index by Kendall and Smith (Smith, Kendall, & Hulin, 1969).
Quality of work life questionnaire is consisting of 40 items which has been designed in 5-point Likert scale (never 1, rarely 2, sometimes 3, most of time 4, always 5). 5 items are related to adequate and fair compensation, 5 items are about safe and healthy work environment, 5 items are about constitutionalism in organization, 5 about preparing the opportunity for continued growth and security, 5 items are related to social relevance of working life, 5 about social integration, 5 about development of human capabilities and 5 about the total life space.
The score of each item is from 1 to 5. Thus, the overall score of this questionnaire will be in range of 40-200. Validity and reliability of questionnaire was confirmed in many studies and α=0.92 has been reported (Mirkamali www There are some criteria for each aspect that measure the individual's feelings about job. The five aspects of this index are consisting of five scales of work type (10 items), supervisor or manager (10 items), colleagues (10 items), preferment in organization (5 items) and salary and benefit (6 items).
Score of each item is in range of 1-5. Thus; the overall scores of job satisfaction varies in range of 41-205. The more score of this questionnaire is indicative of the more job satisfaction. The internal consistency of this questionnaire was reported as 0.89-0.92 by Kendal and Halin (Smith, Kendall, & Hulin, 1969). This questionnaire was used in many studies in Iran and its validity and reliability was confirmed (Heydari, 1998;Ranjbar & Vahidshahi, 2007).
In study by Zamini and Hoseyninasab, this questionnaire was completed by 20 people and chronbach's alpha=0.92 was obtained for the whole of questionnaire and for subscales was 0.85, 0.96, 0.92, 0.87 and 0.84 respectively (Zamini & Hoseyninasab, 2008). The mean score was calculated for each of the components of jab satisfaction and also total score of questionnaire. In current study questionnaires were delivered to faculty members by educational employees for completing during three weeks and then were returned to researcher.
Ethical considerations were adhered, informed consent was obtained and assurance of confidentiality and anonymity was done. Data analysis was done using SPSS 18. Central tendency indexes were used for description of quantitative data and for qualitative variables, frequency and percentage were used. Also, Pearson correlation coefficient and multiple regression were used for measuring the correlation between quality of work life and job satisfaction.

Results
The mean age of faculty members was 40.918 with range of 28-59 years old and the mean of their work experience was 11.98.14 with range of 1-33. Demographic characteristics of subjects are presented in Table 1. A direct and significant correlation was found between quality of work life and job satisfaction of faculty members (r=0.23, p=0.003). Also, there was direct and significant correlation between aspects of social relevance, the total life space and social integration with job satisfaction (Table 2). According to significant values (p=0.000, F=4.92) and the multiple regression analysis about components of quality of work life with job satisfaction, it can be concluded that the regression model was composed of 8 independent variables (aspects of quality of work life) and 1 dependent variable that can explain the changes in job satisfaction.
Based on Multiple regression equations (Y=a+b 1 x 1 +b 2 x 2 +……b k x k), R 2 value shows that the 17 percent of all of the changes in job satisfaction are associated to 8 independence variables in this equation (aspects of quality of work life). In other words, set of independent variables predict the 17 percent of variance of job satisfaction.  Coefficient (regression coefficients) is indicated that the adequate and fair compensation (=0.3) and social integration (=0.4) are predictors of job satisfaction (Table 3).

Discussion
According to study results, there is positive and significant relationship between quality of work life and job satisfaction which was indicating that better quality of work life is associated with more job satisfaction in faculty members.

The study by Conklin (2008) showed that there is a positive and significant relationship between quality of work life and job satisfaction and its changes (Heinonen & Saarimaa, 2009). Results of study in Europe (2008) concerning the health and management efficiency demonstrated that the style of work life as a psychological factor in work environment can increase the efficiency of staff (Kirsten, 2008).
The results of current study about relationship between components of quality of work life and job satisfaction showed that there is a direct and significant relationship between aspects of social dependency, life space and social integration. Zakerian (2012), Hosseini (2008), Othman (2009) andLawler (2007) stated a significant relationship between aspects of work life and job satisfaction (Zakerian et al., 2014;Hosseini et al., 2008;Othman & Mok, 2009;Lawler, Chan Huang, & Yilei, 2007).
According to direct relationship of component of social relevance which is referred to the perception of faculty about social responsibility in system and managers valuing of community rules, thus; it can be created a sense of duty through participation of members in decision making and team working. Also, it can be realized this aspect with using of faculty's thought and idea in policy.
Thus, the organizations can improve all of the aspects of quality of work life in order to increase of job satisfaction.

The aspect of work life space can be strengthened through establishment a balance between work life and other parts of life such as leisure time, education, family life and; with reduction of sensible and insensible job stress.
Results of regression analysis which was done in order to prediction of job satisfaction through the components of quality of work life showed that social integration and adequate and fair compensation are the most important predictors of job satisfaction respectively.
In other studies; constitutionalism, social integration and preparing the opportunity for continued growth and security (Mirkamali & NarenjiSani, 2008), professional satisfaction and status of life space (Zakerian et al., 2014) and organizational climate (safety work environment, providing job opportunities) were as the most important predictors of job satisfaction. Lawler et al. (2007) believed that the safe and healthy work environment, adequate and fair compensation; and job security have positive effect on organizational commitment (Lawler, Chan Huang & Yilei, 2007). The reasons of some differences between results of previous studies with current study are the difference in research population, level of education or difference in data collection methods.
Social integration was one of the factors affecting on quality of work life in faculty members. According to study results, the faculty members were dissatisfied about the work space that is the most important factor in encouraging them for doing their duties and responsibilities and creating a sense of belonging to the organization.
As a result, it is recommended that the university encourage faculty members to creativity and innovation through the preparing of appropriate context for teaching and supporting them by colleagues and managers.
Judging faculty members about objective and observable conditions of organization is affected by their perception and interpretation of organizational environment. Thus; the university can strengthen the sense of belongingness to organization in faculty members through the creating of appropriate and positive working climate and also, can create the proper perception about social responsibility in organization through the using of their expertise and experiences for problem solving in organization.
The next influential factor in job satisfaction with the least mean in both groups of basic science and clinical faculty was fair compensation. Result showed that there is no a proper balance between workload and consumed time and energy and also community standards in financial payment system from viewpoint of faculty members. Thus; it is necessary to revise the appropriateness of salary according to community situations concerning standards and inflation.
