During the primitive civilization and agricultural civilization periods,the functions and structures of various elements within the ecological and economic system were able to develop synergistically.But humans were always passive in the face of nature and cannot yet break free from its constraints and oppression.During the period of industrial civilization,the contradiction between the unlimited expansion of economic system demand and the relative reduction of ecosystem supply became increasingly severe.Its development model had obvious non ecological economic characteristics,which posed a great threat to the sustainable development of human society.The ecological turn in the development of human civilization is an inevitable trend,and the gradual replacement of industrial civilization by ecological civilization will become an objective fact.Ecological civilization has overcome the non ecological economic nature of industrial civilization and established an ecological economic operation mode that promotes and transforms economic and ecological systems in both directions.It has achieved a perfect combination of ecological operation of social and economic systems and economic operation of natural ecosystems,and harmonious,coordinated,and win-win development of economic society and natural ecology. 展开更多

This study is presenting a Policy analysis of the related environmental challenges associated with the development of socio-economic activities between China and East African countries. The author thinks that Socio-economic issues and economic development have a direct impact on the environment hence need to be studied for the purpose of policy formulation. This study analysed the policies on environmental issues in China and its five-year economic plan. Furthermore, this study examined what the Chinese government has done about socio-economic activities and what lessons are available for East African countries. Finally, this paper proposed possible solutions for East African countries on environmental challenges associated with the development of socio-economic activities with the potential for combining economic and ecological interests in East Africa. This study can help (potential) Government officers, policymakers, and regulators to assess environmental risks with lessons from China. 展开更多

Financial Power and Its Strategic Significance A financial crisis hit Asia in 1997. It was both a predatory monetary war a-gainst developing nations launched by the hedge funds and a scramble for fi-nancial supremacy among the monopoly capital in America, Western Eu-rope and Japan. Indeed, the term "Asian financial crisis" is a misnomer. It can nolonger faithfully reflect the scope and essence of the financial storm. Over the pasttwo years, financial turmoil has visited upon Russia and Brazil and has shaken theentire capitalist economic system. In this crash, while Asian nations have 展开更多

With the escalation of the Ukraine crisis,Russia’s policy of“Turn to the East”has evolved into“Turn to the Non-West”at an accelerated pace.Involving both a shift of focus in diplomacy and economics and the“de-Westernization”in financial and ideological areas,it has become a strategy to break through Western diplomatic and economic blockade.The transition will continue in the medium term,but adjustments or twists and turns are likely under the influence of internal and external factors. 展开更多

China is Korea’s main trade partner in East Asia and one of its key economic and trade partners worldwide.The two countries have complementary industrial structure and a long history of trade exchanges.However,against the backdrop of a return to global trade protectionism and the politicization of international affairs with Yoon Suk-yeol coming to power,South Korea has undertaken a strong trade shift toward the United States(US),triggering a change in the pattern of economic cooperation in East Asia and challenging the regional trade structure.A review of the trade policy agenda of the Yoon Suk-yeol administration toward the US and China,along with a comparative review of Korea’s foreign trade stance under Moon Jae-in,allows for an analysis of the turnaround and characteristics of Yoon’s trade policy toward China during his tenure.The implications for global trade governance and regional security are further analyzed with an aim of finding a Nash equilibrium in trade cooperation among East Asian countries. 展开更多

The university-industry engagement serves as a cooperation that gives benefit to both parties. The universities and the industries are dependent on each other as the university's role is to produce human capitals to work at the industries, and the industries on the other hand need human capitals to run their business. However, this kind of dependency could raise issues that cause difficulties for both parties if the relationship is not checked and balanced from time to time. The universities should be aware of the industries' changing needs as time changes. Hence the programmes that they offer to their students should take into consideration the industries' needs. This research was to identify the current practices of the university-industry engagement, to appraise the factors contributing to the effectiveness of the university-industry engagement involving UMP (Universiti Malaysia Pahang) and the identified industries, to map the prospects and challenges that UMP faces in the university-industry engagement and to propose the best approaches that the university could engage to provide high class human capitals to work at the industries. This research employed a survey in the form of interviews and expert group discussions. The results show that there is still a mismatch in the university-industry engagement. The representatives from the industries felt that they should be actively involved in the university's activities, especially in teaching, learning and industrial training for students. They had given a few suggestions to be forwarded to the university 展开更多

Introduction:Economic evaluation studies demonstrate the value of money in health interventions and enhance the efficiency of the healthcare system.Therefore,this study reviews published economic evaluation studies of public health interventions from 26 Middle East and North Africa(MENA)countries and examines whether they addressed the region’s major health problems.Methods:PubMed and Scopus were utilized to search for relevant articles published up to June 26,2021.The reviewers independently selected studies,extracted data,and assessed the quality of studies using the Consolidated Health Economic Evaluation Reporting Standards(CHEERS)checklist.Results:The search identified 61 studies.Approximately half(28 studies;46%)were conducted in Israel and Iran.The main areas of interest for economic evaluation studies were infectious diseases(21 studies;34%),cancers(13 studies;21%),and genetic disorders(nine studies;15%).Five(8%),39(64%),16(26%),and one(2%)studies were classified as excellent,high,average,and poor quality,respectively.The mean of CHEERS checklist items reported was 80.8%(SD 14%).Reporting the structure and justification of the selected model was missed in 21 studies(37%),while price and conversion rates and the analytical methods were missed in 21 studies(34%).Conclusions:The quantity of economic evaluation studies on public health interventions in the MENA region remains low;however,the overall quality is high to excellent.There were obvious geographic gaps across countries regarding the number and quality of studies and gaps within countries concerning disease prioritization.The observed research output,however,did not reflect current and upcoming disease burden and risk factors trends in the MENA region. 展开更多
