Climate change is an issue of major concern *** impact on the natural and human environment is studied intensively,as the expected shift in climate will be significant in the next few *** experience shows that the effects will be critical in coastal areas,resulting in erosion and inundation phenomena *** addition to that,coastal areas are subject to "pressures" from upstream watersheds in terms of water quality and sediment *** present paper studies the impact of climate change on sediment transport and morphology in the aforementioned coupled *** study regards a sandy coast and its upstream watershed in Chalkidiki,North Greece;it is based on:(a)an integrated approach for the quantitative correlation of the two through numerical modeling,developed by the authors,and(b)a calibrated application of the relevant models Soil and Water Assessment Tool(SWAT)and PELNCON-M,applied to the watershed and the coastal zone,*** examined climate change scenarios focus on a shift of the rainfall distribution towards fewer and more extreme rainfall events,and an increased frequency of occurrence of extreme wave *** indicate the significance of climatic pressures in wide-scale sediment dynamics,and are deemed to provide a useful perspective for researchers and policy planners involved in the study of coastal morphology evolution in a changing climate.

Thirty years have passed since China first adopted the policy of reform and opening up to the outside. Reviewing and appraising the advantages and disadvantages of the government＇s energy restructuring policy in the intervening years is of great importance to the consideration of future reform and opening-up efforts in this industry. Energy production and supply have been a major part of the national economic restructuring. In this paper, the author proceeds from three angles to review and assess the reform and opening-up efforts in the energy industry, and suggests some direction and priorities for its restrueturing in the future.

Brazil, Russia, lndia, China and South Africa （BRICS） have come together economically as a group since 2009. Their cooperation has been driven not only by economic and political factors, but also the failure of the existing global economic governance framework to satisfy the real needs of these countries. In this paper, we analyze how the BRICS moved from a financial category into a political group, and are progressively developing from a dialogue-based platform into a full-fledged mechanism of long-term coordination on a wide range of key issues relating to the world economy and politics. We also analyze how the BRICS have coordinated their positions in the G20, pushing for deep reform in global governance. Then, given the major hindrances to cooperation among the BRICS, including the challenge of economic transition, weak geopolitical links, complicated internal and external relations and inadequate governance capabilities, the present paper speculates on how the BRICS can use the opportunity arising from China taking the G20 presidency in 2016 to improve the cohesiveness and influence of the BRICS in terms of their agenda, organization and deliverables.

Introduction: COVID-19 is a global public health emergency that can cause acute respiratory distress syndrome. In countries where tuberculosis (TB) is endemic, coinfection of COVID-19 and TB is often encountered, which increases the risk of developing severe forms of COVID-19. Objectives: The aim of this study was to determine the prevalence of COVID-19/TB coinfection at the Epidemic treatment center (ETC) in Saint-Louis (Senegal) and to describe the epidemiological, clinical, paraclinical, and outcome profile of co-infected patients. Patients and Methods: This is a retrospective, cross-sectional, descriptive cohort study based on the records of COVID-19/ TB co-infected patients who were hospitalized at the ETC in Saint-Louis (Senegal) over an 18-month period from March 2020 to September 2021. Results: Out of a total of 454 hospitalizations, we collected records of 9 patients co-infected with COVID-19/TB, resulting in a prevalence of 2%. The study included patients with a median age of 34 years (range: 10-86 years), with a male predominance (7 cases) and a sex ratio of 3.5. The majority of patients (88.9%) had severe forms of COVID-19. Dyspnea and cough were reported in all patients (100%). Pulmonary TB was the most frequent localization, with 9 cases. The diagnosis of COVID-19 was confirmed by nasopharyngeal PCR in all patients (100%). Bacilloscopy was positive in 3 out of 5 cases. One patient tested positive for GeneXpert? MTB/RIF without rifampicin resistance. All patients were prescribed the hydroxychloroquine-azithromycin combination and anti-tuberculosis treatment. Out of the nine patients, four recovered (44.4%) and five died (55.5%). Conclusion: COVID-19/TB coinfection had a low prevalence in our cohort, but was associated with a high mortality due to the frequent occurrence of severe forms of the disease.

This paper investigates the extent of competition between China and lndia in the world and ASEAN markets. The analysis is undertaken using the concept of revealed comparative advantage, relative market shares, long-term trend analysis and statistical tests of convergence. In the context of the ASEAN market the evaluation of competition between India and China has been undertaken with special reference to the prior implementation of the ASEAN-China Free Trade Area relative to the ASEAN-India Free Trade Area. The results suggest that threat perceptions at the product level might currently prevail for both economies from each other across all sectors in both markets even though the intensity of the competitive threat varies across products. However, long-term trend analysis shows that the patterns of comparative advantage of India and China are evolving along divergent paths and, therefore, competition between the two economies might not be a major issue.

Since the global financial crisis broke out in 2008, China＇s nonfinancial corporate debt has been rising steadily and rapidly, posing serious threat to China ＂s financial stability. China ＂s rising corporate debt is mainly attributable to three factors： worsening capital efficiency, worsening corporate profitability and high funding costs. Based on a dynamic recursive model developed in the paper, we simulate the trajectories of China＇s corporate debt-to- GDP ratio, and find that if China fails to reverse the current trends in capital efficiency, corporate profitability and financing costs, China ＂s nonfinancial corporate debt-to-GDP ratio will continue to rise without converging to a limit. Against most economists ＇ intuition, given the current trends of changes in parameters, higher economic growth will not help China to escape the corporate debt trap. On the contrary, it will make China ＂s corporate debt problem even worse. To avert a corporate debt crisis, China needs to speed up the structural reform and change the growth paradigm so as to enhance capital efficiency and firms＇ profitability, while reducing firms ＇financing costs.

At present, the development of renewable energy relies mainly on government support. The government invests in a considerable number of projects to improve public welfare and to assist in poverty relief If China is to replace fossil fuels on a large scale with renewable energy sources, the production costs and prices of renewable energy must be brought down. All countries are facing the challenge of moving to a more secure and low-carbon energy system without weakening economic and social development. In this regard, China is facing an even greater challenge in terms of economic cost, as cheap coal remains the main energy form. Technical innovation and industrialization in the area of renewable energy is an important means of lowering cost. China is in for a period of high-speed development of its economy and the rising demand for energy is irreversible. If the technical progress and development speed of renewable energy lags behind the growth in demand, it will be difficult to realize the improvement of its energy structure.

The central theme of this paper ls that Lnlna s macroeconomic development into three distinct stages with significant trend changes. Market-oriented reform and opening to the outside world provide main driving forces for the convergence. However, the gradual reform and some inappropriate policies have caused serious ups and downs in China＇s macroeconomic performance.
