The South Caucasus region is experiencing crises that have continued for many years. Russia's war with Georgia in 2008 and the Armenian-Azerbaijani conflict over the Nagorno-Karabakh region after the collapse of the Soviet Union (1991) changed the security order in the South Caucasus. Russia has interests as a global player in the South Caucasus region and Kremlin considers it's near abroad as its backyard and exclusive sphere of influence. This article uses a descriptive-analytical method as well as the theory of regional security of Barry Buzan to answer the question of what is Russia's security strategy towards the South Caucasus region. The main hypothesis emphasizes that Russia's strategy in the South Caucasus region is to prevent securitization of the region against its economic and political interests, as well as prevent the influence and presence of NATO, in the region. The results show that in tensions with Georgia, Russia seeks to prevent Western interference and urges them to recognize the separation of Abkhazia and South Ossetia from Georgia. On the other hand, Russia's foreign policy in the face of the Nagorno-Karabakh crisis is to maintain a balance between the two parties involved, Armenia and Azerbaijan, to cooperate with both countries, and to resolve the Nagorno-Karabakh conflict by a political solution, not a military one. The purpose of this article is to examine Russia's security strategy in the South Caucasus, with a particular focus on Georgia and the Nagorno-Karabakh crisis from the beginning of the crisis until 2020. And then it offers specific reasons for the confrontation between Russia and the West, as well as Iran's role in regional security issues. 

Foreign policy is implemented in the international environment with special and various tools; one of those tools witha prominent role in diplomacy. However, along with traditional diplomacy, with the emergence of new actors after the Cold War and the entry into the age of communication and technology, diplomacy took new forms. One type of diplomacy that has received more attention in recent years is science diplomacy. So far, scientific diplomacy in the world and especially in Iran has not been fully and sufficiently studied and the interest in this issue is more related to the development in recent years. Additionally, due to its less attractive scientific aspect in the world compared to many other countries, Iran should strengthen its international scientific cooperation networks. So, this article focuses on this issue and the main question is how the Islamic Republic of Iran performed in the application of science diplomacy in the field of medical sciences with Eastern Europe between 1991 and 2018. The hypothesis of this research is: The performance of the Islamic Republic of Iran in various dimensions of science diplomacy including memorandums of understanding and agreements, collaboration desks, international meetings and visits, summer schools, international seminars and congresses, visiting professors, and joint articles towards the Eastern European region from 1991 to 2018 has been increasing. The present study is applied research with the experimental scientific method and hypothesis- deductive research strategy and the review of these activities based on the indicators of science diplomacy shows that during the years 1991 to 2018, these activities have increased significantly in most of the proposed indicators.

The emergence of future powers is one of the most important features of the contemporary international system. The collapse of the Soviet Union and a new wave of globalization of the economy and the movement of Russia and China towards a market economy in the early 1990s forced governments around the world to reconsider their foreign policies. At this time, India was experiencing the worst economy of its time. The demonstration of the inefficiency of state socialism made New Delhi think for a change. In the present study, by using the explanatory-analytical method, we seek to answer the question "How and with what methods and tools does India pursue its strategy towards becoming a world power?" The proposed hypothesis for the question is that “India seeks to achieve the position of a global superpower by special emphasis on domestic strategies and relying on a pragmatic foreign policy." Therefore, due to the increasing importance of emerging powers during the transition of the international system, the analysis and examination of characteristics, perspectives and global effects of their empowerment can deepen our understanding of the evolvinginternational system.

Introduction: The present study aimed to compare hip muscle resistance training with and without feedback on trunk, pelvis, and lower extremity motions in frontal and sagittal planes among active females with dynamic valgus. Materials and Methods: Twenty-Nine active females (Mean±SD age: 22.8±2.4 years, height: 1.70±0.6 m, weight: 69±7.1 kg) were randomly assigned to a hip muscle resistance training with feedback group (n=15) or a hip muscle resistance training without feedback group (n=14). Both training programs lasted 6 weeks (3 sessions/week). The peak angles of lateral trunk flexion, contralateral pelvic drop, hip flexion, knee flexion, and valgus during single-leg drop landing and single-leg vertical drop jump were assessed in the research participants at baseline and 6 weeks post-training. Unipodal functional screening tests were captured with two standard digital video cameras. Results: After 6 weeks, significant differences were observed in knee valgus and lateral trunk flexion, contralateral pelvic drop, and knee flexion angles, i.e., compared between hip muscle resistance training with feedback and hip muscle resistance training without feedback (P<0.05), except for non-dominant leg hip flexion in single-leg vertical drop jump (P>0.05). Conclusion: In the explored active females with dynamic valgus, hip muscle resistance training with feedback seems to be better at improving trunk, pelvis, and lower extremity motions in frontal and sagittal planes, compared to hip muscle resistance training without feedback; however, no significant difference was observed concerning hip flexion during single-leg vertical drop jump between the study groups.
