Minerals in nature are one of the most valuable treasures on the earth, which due to the limitation of these resources on land and its heterogeneous distribution in different countries, has made human beings think about extracting the new resources. The limited mineral resources on land and the heterogeneous distribution of these substances in different countries have made human beings think about extracting and using the resources of other parts of the earth and even other planets. Deep-sea mineral resources can be considered as a reliable alternative to compensate for the limitations of land resources. The developed countries were more concerned with the use of these resources than others because, given the dependence of their economies on third-world mineral resources, the development of offshore resources could mean the liberation of their economies from this dependence. In political and scientific circles, the concept of the common heritage of humanity was gradually introduced, based on which activities related to mining in the deep sea. The method of this research is a descriptive-analytical study using library resources, the study of articles, and a review of environmental treaties and related internet resources. The result of this research shows, that none of these legal systems in the field of responsibility can respond to the challenges independently. This research tries to provide a legal solution by considering the opinions of environmental experts, an executive solution about achieving new financial resources based on combined systems of environmental responsibility.

The world witnessed a change in the arrangement of international actors after the Second World War and the rise of international organizations in the international landscape. The International Maritime Organization (IMO) was one of these entities, acting as the UN specialized agency in maritime affairs. This study mainly aims at reviewing the regulatory role of the IMO, particularly the Port State Control (PSC) regime, by addressing its concept, as well as the legal basis and the control procedures. This mainly descriptive–inductive study describes and analyzes the legal bases of the PSC. Generally, IMO is identified with two types of functions: legislation and regulation. IMO’s regulatory function is reflected in two main tools, namely, the Audit Scheme of its Member States and Port State Control (PSC). With its supplementary nature, PSC is in fact an efficient maritime system for the safety and protection of the marine environment, encouraging states to watch for the safety of ships other than those flying their flags, especially those visiting their ports. This control system has led to an effective and efficient implementation of IMO rules and regulations.

Life expectancy and infant mortality are two major indicators for assessing the efficiency of every social health system. The bulk of literature on health economics is related to unilateral influences of macroeconomic variables on health sector indices and less attention has been paid to bilateral and simultaneous effects. Therefore, this paper aims to examine the bilateral and simultaneous impacts of the key macroeconomic variables on life expectancy and infant mortality in Iran during 1981-2018. To this end, by considering the government’s health care expenditures and GINI coefficient, a system of simultaneous equations based on variables of life expectancy, infant mortality and economic growth is developed. The findings indicated that income growth per capita affects the growth of life expectancy index positively by 31%, but the growth of social-class differences or income inequality has a negative effect on this index. Moreover, the escalation of health care budget in Iran has led to slumps in infant mortality rate by 83%. Such outcome exhibits the significant role of government, parliament and legislature in approving and improving the budget of the Ministry of Health and facilitating achievement of higher social-health standards. Finally, findings of present study reflected the simultaneous and positive effects of improving growth of life expectancy and reverse effect of infant mortality growth indices on the economic growth of Iran. The estimations provided evidence on the interactions between enhancing the macroeconomic conditions and improving the health economy indicators and existence of a reinforcing loop between them.
