Europe is increasingly dependent on Russian natural gas imports. As Ukraine is the main transit country for gas trade between the two sides, the military conflict between Russia and Ukraine, which started in 2014 and has not stopped yet, has led to Europe's gas trade with Russia receiving an impact. Due to the importance of natural gas and the fact that this war was the largest in Europe since World War II, the trade relations between the European and Russian natural gas markets before and after the Russo-Ukrainian war and the diversification of natural gas in Europe have been studied by many scholars. This paper uses a review to summarize and sort out the relevant literature based on game theory to study the gas market trade relations in Europe before and after the Russo-Ukrainian War. According to these scholars, the trade relations between Russia and Europe in the gas market will continue to cooperate despite the impact of the Russo-Ukrainian war. The interruption of gas exports to Ukraine and the construction of pipelines bypassing Ukraine are acceptable to Russia and Europe. Iran, Azerbaijan, Turkmenistan, and Iraq, along with the United States, should actively invest in expanding their gas export capacity to have the opportunity to serve as an alternative to Russian gas and make Europe less dependent on Russian gas imports. This paper provides an understanding of the implications of the Russian-Ukrainian conflict for the world in terms of gas trade. This paper provides a reference for related studies, and to understand the impact of the Russian-Ukrainian conflict on the world from the perspective of the gas trade.

After studying how virus spread, people find that wearing masks can effectively reduce the probability of infection. However, there are still number of people struggling whether to wear masks or not. In the current paper, based on the probability of infection we construct two matrix models, one for standard players and one for players who have been recovered form Covid-19, to analysis the expected payoff of to being a mask wearer or non-mask wearer. Comparing the expected payoff as number of people increasing in the model, we find a critical point that people are indifferent of wearing masks and not wearing masks and name it as indifferent ratio. According to the results of the model and corresponding analysis, governments are suggested to enforce policies such as wearing masks in public and enable certain social distance. For people who have been recovered from Covid-19, they can choose not to masks in places where few people around them.

The mobile phone market is always changing. In recent years, fashionable and cheap mobile phones like OPPO have become consumers' preferences, and their market share is also expanding. This research will make predictions about the development of OPPO in the next five to ten years. To make the forecasts reliable and convincing, the SWOT model and data from "Counterpoint" and "The Economic Times" are used. Generally, the international mobile phone market is slowly recovering, but the shortage of hardware components for Chinese brands, such as OPPO and VIVO, and the crisis between Ukraine and Russia made the expected fast recovery fail. For OPPO, its expansion is restricted by China's policy of COVID-19 and it faces serious shortages on making some core hardware components, hence in the future 5 years, OPPO is not expected to occupy much market share. However, in a future decade, it is hard to say. Although the influence of China's COVID policy restriction and the Ukrainian War is expected to disappear, the key restriction for OPPO is the limitation on components. OPPO should develop some core components independently to reduce the impact of the external supply market on the company's expansion. In addition, OPPO pays more attention to offline sales, and its sales have been greatly affected during the COVID-19 period. In the future, OPPO can expand online and other channels and can flexibly switch if similar emergencies happen in the future.

Since China’s reform and growth, the continuous development of the social economy and the constant improvement of people’s living standards have been the mainstream of society’s development. However, with the foundation and improvement of China’s market economy and the ongoing promotion of China’s urbanization process, the number of impoverished people among urban residents is increasing, and the gap between the rich and the poor is widening. This paper uses Literature research, data collection and analysis, and MPI to explore the dimensional deconstruction of urban poverty and find that the existence and widening of the income gap is the main cause of structural poverty in the country. Also, the employment dimension has the greatest impact on multidimensional urban poverty. The employment dimension has the greatest impact, followed by the education dimension. These problems can be solved by strengthening income adjustment measures to narrow the income gap, ensuring labor force employment, and improving the social security system. The paper can better help solve the problem of urban poverty and reduce the number of urban low-income families.

In terms of the state of Europe, Michael E. O’Hanlon believes that even if the war in Ukraine ends soon, the events so far have changed the security environment in Europe. The tripwire strategy NATO has used in the Baltic states and Poland since about 2017 must now be replaced by a permanent forward defense posture of modest size and scope. Starting with two external factors, aid and sanctions, this paper uses a comparative political science approach to construct a military and economic model of the Russo-Ukrainian war by September 2022. This paper finds that Ukraine is constrained by its strength and weapons in the face of advanced operational command concepts and cannot effectively stop Russia. This ideological difference has led to a failure to achieve a balanced model of war, while at the same time, we note that all sides are also managing the risk of war escalation. The lack of planning for economic sanctions against Russia and the vacillating attitudes of the West, including the US, make the course of the war and subsequent reconstruction far from certain.
