In the discussions about social and economic justice, the criterion of choosing an approach is the effect which justice exerts on theoretical and practical aspects. This idea increases the importance of exploring Islam's approach to justice, and balance. The present paper examines the hypothesis of conformity in martyr Șadr and Motahhari's views on balance in order to make explicit Islam's approach to balance. The research which relies on a library method, comes up with three main results: first, according to martyr Sadr's approach, balance is based on two principles: reducing great inequalities and earning an income which ensures a respectable standard of living. Second, martyr Motahhari's approach represents his views on natural rights. Third, there is no inconsistency between martyr Sadr's approach and that of martyr Motahhari's, in spite of some unfounded claims.

Despite the importance of the concept of rights to protect individual existence and the institution of public interest to protect collective life, and of course the necessity of not ignoring these two as the two wings of flight in the path of achieving justice, the question of which takes precedence is unavoidable. Since absolutely no one agrees with anarchy, the rights of citizens cannot be considered unlimited, even in completely conventional conditions. Therefore, a balance must be established between individual claims and collective demands. However, it should be noted that balance is not a static and stable process, but dynamic, changing and flexible. Therefore, it seems that the main advantage of the "balance model" compared to other methods of conflict resolution is its flexibility and high sensitivity to the context of the discussion. But what is undoubtedly necessary and has been the constant concern of the authors of the upcoming article, is that the motto of balance and balance is exposed to theorizing and analyzing carefully, and its practical applications are determined to some extent. For this purpose, the explanation of the general content of the balance theory and its subsequent introduction of the triple tests, and of course how to use them, puts the claim of this article on a firmer footing.

Introduction: Migraine is the most common type of chronic headache. Stress can trigger migraine and effect on the duration of migraine attacks.. One of the main reasons of job stress is inappropriate job design.The aim of the current study was to investigate the new cases of migraine regarding models of effort-reward imbalance and demand-control imbalance in job.Methods: Two job designs namely effort-reward imbalance and demand-control imbalance models were applied to predict new-onset migraine. Samples were 3338 persons who worked in industrial companies in Iran. Four instruments were used (job stress, ERI questionnaire, demand control and Self-reported questionnaire for migraine) Age and the economic status were used as covariate variables. Binary logistic regression analysis and odd ratio were used for analyzing the data. Statistical analysis was performed in M plus 4.2 Software.Results: The findings indicated that risk of increasing migraine was increased among those with high effort-reward imbalance (odd ratio 1.28 to the reference group) and those who have little control over their jobs (odd ratio 1.11 to the reference group) as well as people who are strongly committed to their work (odd ratio 1.17 to the reference group).Conclusion: Migraine could be produced by inappropriate work design. Therefore, work redesign especially among the persons experienced the effort-reward imbalance may decline new onset migraine.

Assessment of the ability of employees to work without risk to health and safety for themselves and others is the concept of job fitness. The five main criteria, i.e. work capacity, risk of health and safety, ethical indices, economic indicators and indicators of legal, occupational health physician must be considered in assessing fitness for work.This review article consists of different parts including: occupational fitness evaluation indices, safety and health risk, workers' capacity, legal and moral indices, economical index, evaluation tools, decision making process, consequences and challenges. Naturally, for each of the mentioned indicators there is a tool to assess the sensitivity, specificity and cost-effectiveness.Consequences of job fitness assessment can range from suitable to unsuitable. Changes in maintenance and adjustment of work or working conditions should be considered in assessing job fitness. But with all the explanations, in many cases an occupational health physician may face problems in decision making for job fitness. He/She may not be able to make a precise decision which is probably due to different causes such as lack of appropriate tools and atandards, workers' malingering, social laws and etc.
