This paper addresses measuring the comparative advantage of fast moving auto pats during a five-year period based on Domestic Resource Cost method (on the basisi of industrial accounts method). Due to taking advantage of yp-to-date, shadow prices etc, using this new approach for evaluating the DRC in the above-mentioned products is more dfficient than previous methods. So the present paper firstly addresses measuring the indices of DRC and then - after introducing the methodology of the new approach to DRC - addresses meansuring the comparative advantage of several selected companies producing fast-moving auto parts and analyses it.

Iran is the eighth country in the world by producing 74 thousand and 577 tons of honey in 2013. It also ranks fourth in the number of hives in the world. In 2013 more than 74 thousand tons of honey is produced in the country valued at 1, 149 million dollars. There is a high potential for production of export one hundred percent pure honey in Iran so more than 2 billion dollars acquired by exporting honey and it’s accessories such as pollen, royal jelly and bee venom. Therefore it can be used as in our non-oil export baskets. In this article, index of comparative advantage in the export of honey in the country for 2009-2012 are calculated. For this purpose, the index of revealed comparative advantage (RCA), Location Queficient (LQ) and domestic resource cost (DRC) are computed. Result of study shows Ardabil and West Azerbaijan comparative higher advantages among country’s provinces in production of honey. According to the results, index of domestic resource price, Iran has comparative advantage in production of honey.

Background  The Eastern part of the Democratic Republic of Congo (DRC) has been affected by armed conflict for several years. Despite the growing interest in the impact of these conflicts on health service utilisation, few studies have addressed the coping mechanisms of the health system. The purpose of this study is to describe the traumatic events and coping mechanisms used by the health zones (HZs) in conflict settings to maintain good performance.Methods  This multiple case study took place from July to October 2022 in four HZs in the South Kivu province of DRC. HZs were classified into “cases” according to their conflict profile: accessible and stable (Case 1), accessible but remote (Case 2), unstable (Case 3), and intermediate (Case 4). Eight performance indicators and the amount of funding provided to the HZs by non-governmental organisations (NGOs) were recorded. A graph was created to compare their evolution from 2013 to 2018. A thematic analysis of qualitative data from individual interviews with selected health workers was conducted.Results  Both battle-related events (war and its effects) and non-battle-related events (epidemics, disasters, and strikes) were recorded according to the case conflict-profile. Although the cases (3 and 4) most affected by armed conflicts occasionally performed better than the stable ones (1 and 2), their operational action plan was poorly carried out. The coping mechanisms developed in cases 3 and 4 were the deployment of military nurses in preventive and supervisory activities, the solicitations of subsidies from NGOs, the relocation of healthcare facilities and the implementation of negotiation strategies with the belligerents.Conclusion  Armed conflict results in traumatic events that disrupt the execution of the operational action plan of HZs. The HZs’ management team expertise, its strong leadership, and substantial financial support would enable this system to develop reliable and sustainable adaptive mechanisms.

The comparative advantage of mining ores from production and exports point of view is an important factor in economic planning. This issue is central in developing countries. In Iran, promoting the non-petroleum exports and hence departing from the single-product economy to a wider range of exports is a major issue. Also, This is one of the main objectives of the Forth Economic and Social Plan of Iran. Mining reserves play an important role in providing the raw materials used in related industries. Spread due to the geographical and geological situation of Iran, there are significant and valuable ore reserved situated in different parts of the country. This is an excellent potential for the mining investment. In this paper the comparative advantage of operating copper mines in Iran, from production to exports stage, is evaluated by applying the Domestic Resources Cost (DRC) method. Finally, this study recommends a regime for promotion of production and export of the ore. Accuracy of the results obtained in the paper is tasted by comparing these with the real standard ratios being used in other countries.

This paper focuses on the dynamics of Mpox, a viral disease, in Nigeria and the Democratic Republic of Congo (DRC) by employing mathematical modeling and parameter estimation techniques. Utilizing optimization methods, the model parameters were calibrated to match the observed Mpox cases and deaths. The basic reproduction number (R0) was calculated for each region, indicating the disease’s transmission potential, and a sensitivity analysis was conducted to identify key parameters influencing disease outcomes. Subsequently, numerical simulations were performed to assess the impact of intervention scenarios on Mpox cases and deaths. The primary goal is to create mathematical methods that can evaluate the risk of Mpox transmission and implement control measures in Nigeria and the DRC, potentially extending the findings to other countries. Results show that reducing parameters related to transmission and progression significantly decreases disease burden, highlighting the importance of preventive measures. These findings provide valuable insights for policymakers and public health officials in designing effective strategies to mitigate Mpox’s impact on human populations.

The comparative advantage of minerals from production and export point of view is one of the important key factors in economical activities. This issue is central in the developing countries. In Iran, promoting the non-petroleum export and diverting from the single-product economy to a wide range of exports is a major issue. This is an excellent potential for the mining investment. In this paper, the comparative advantage of operating gold mines in Iran, from the production to the export stages, is evaluated by the implementation of the Domestic Resources Cost (DRC) method. Finally this study recommends a regime for the promoting of the production and export or importing the ore. Accuracy of this method is examined by the comparing the result with the real standard ratio, being used in the other countries.
