This drought started earlier than other previous droughts. Although some rain fell during the austral summer, totals remained below average. Higher temperatures during austral winter and spring 2023, which affected most of Central South America, then aggravated drought conditions. This coincided with an intense El Niño and abnormally warm tropical North Atlantic Ocean temperatures since mid-2023. Decreased rainfall across the Amazon basin, negative anomalies in evapotranspiration (derived from latent heat) and soil moisture indicators, as well as increased temperatures during the dry-to-wet transition season, September-October-November (SON) 2023, combined to delay the onset of the wet season in the hydrological year 2023-24 by nearly two months and caused it to be uncharacteristically weak. SON 2023 registered a precipitation deficit of the order of 50 to 100 mm/month, and temperatures +3˚C higher than usual in Amazonia, leading to reduced evapotranspiration and soil moisture indicators. These processes, in turn, determined an exceptionally late onset and a lengthening of the dry season, affecting the 2023-2024 hydrological year. These changes were aggravated by a heat wave from June to December 2023. Drought-heat compound events and their consequences are the most critical natural threats to society. River levels reached record lows, or dried up completely, affecting Amazonian ecosystems. Increased risk of wildfires is another concern exacerbated by these conditions.展开更多

In the Republic of Korea(ROK), twenty-seven climate technologies were selected to boost the greening of existing industries and to develop new green industries to promote a sustainable climate technology development strategy. Rechargeable battery technology, carbon capture and storage(CCS) technology, smart grids, and sewage treatment are all research areas expected to have tangible outcomes in the forthcoming years. As such, they were included in a comprehensive R&D plan for climate technology advancement, which places an emphasis on climate technology development and commercialization strategy. In this study, the R&D plan of the ROK is reviewed by examining its six core climate technology programs: solar cells, fuel cells, bioenergy, rechargeable battery technology, information technology(IT) applications for the power sector, and CCS technology in detail. The climate policy in the ROK aims to find new economic growth engines and to develop new business opportunities while actively participating in international efforts to combat climate change.展开更多

Typically, a small municipality often owns a small facility. However, a large facility which can run continuously at high temperature with stability would be preferable if the dioxin generation mechanism is to be considered. Accordingly, municipalities in contiguous areas should cooperate mutually by using a large facility. To evaluate the effect of the concentration of large facilities, the authors created a GIS (Geographic Information System) based database of combustible waste generation at town level in Shizuoka Prefecture. Focusing on large facilities in Shizuoka City and superannuated facilities in Shida area, the authors evaluated the effect of the concentration of large facilities in Shizuoka city on utilization rate of facilities, energy balance and CO2 emissions. Our results showed the amount of light oil consumption and CO2 emissions increased because the mileage distance of garbage collection trucks becomes longer. However, the utilization rates of facilities and the amount of energy recovery from waste are improved. From these standpoints, the authors conclude that the concentration of large facilities is better compared to a single municipality based facility.展开更多

This study produced the following results: (1) Common mistaken collocations are seen in the writings by Chinese non-English and English majors; specifically, both English majors and non-English majors made more lexical collocational mistakes than grammatical collocational mistakes in terms of the total number of mistakes and in the type of mistaken collocations; (2) No evident relationship between the correct usage of collocations and coherence is found in the writings of non-English majors as compared to that of English majors. Thus, we can conclude that with the development of skills with the English language, the relationship between the correct use of collocations and coherence becomes increasingly stronger.展开更多

Furthermore, it explains a new methodology for measuring resilience based on the theory of springs and qualitatively appraises the resiliency of Minamisanriku town as a case study. Minamisanriku is a tiny coastal town located in the northeastern part of the Miyagi Prefecture, Japan. The town was affected by an earthquake on March 11, 2011, with a magnitude of 9.0, followed by a tsunami. According to the authors’ previously proposed conceptual framework, resilience should be considered by dividing it into three components: onsite capacity, instantaneous survivability, and the recovery potentiality of an area. Each component of the framework depends on two or three factors that can be measured using different indicators and sub-indicators. Onsite capacity is the ability of a given place to withstand a tsunami before it arrives, and it has been considered indispensable for the prevention of a tsunami. Instantaneous survivability is the power to be alive at the point of a disaster climax. Returning speed to its normal daily routines once a catastrophe is over is called recovery potentiality. It is understood that strengthening onsite capacity by moving residences to higher ground, building seawalls and paved roads, relocation of fishing industry infrastructure, and land elevation in Minamisanriku town makes it a benchmark for resilient cities.展开更多

The paper also focuses on the post-reform period, after 2005, allowing greater ftexibility of the RMB to explore the change in the role of the Chinese import share in determining the trend in the US exchange rate pass-through. Evidence reveals that China's share of US imports has a negative effect on the exchange rate pass-through. However, this negative effect has been moderated to a negligible level since China's exchange rate reform. An important implication is that the exchange rate flexibility of the RMB has been raised to a significant level may no longer cause distortion in the US competitive environment and prevent the USA from adjusting current accounts.展开更多

In this article, we have studied the possible effects of introducing three energy recovery processes either as a single or combination approach, refuse derived fuel production,incineration and waste power generation, and methane gas recovery from landfill and power generation in Ulaanbaatar, Mongolia, as a case study. We concluded that incineration process is the most suitable as first introduction of energy recovery. To operate it efficiently,3Rs strategies need to be promoted. And then, RDF production which is made of waste papers and plastics in high level of sorting may be considered as the second step of energy recovery.However, safety control and marketability of RDF will be required at that moment.展开更多

Our two-country model incorporates the New Keynesian features of price stickiness and monopolistic competition based on the cost channel of Ravenna and Walsh (2006). In particular, in response to asymmetric productivity shocks, firms in one country achieve a more efficient level of production than those in another economy. Because the terms of trade are directly affected by changes in both economies' output levels, international trade creates a transmission channel for inflation dynamics in which a deflationary spiral in foreign producer prices reduces domestic output. When there is a decline in economic activity, the monetary authority should react to this adverse situation by lowering the key interest rate. The impulse response function from the model shows that a productivity shock can cause a real depreciation of the exchange rate when economies are closely integrated through international trade.展开更多
