The overallseroprevalence rate of H. pylori infection is 44.2% in China, 37.6%-43.2% in Japan,and 51.0% in South Korea. H. pylori can cause peptic ulcer disease and gastriccancer. East Asian countries have high rates of gastric cancer (age-standardizedincidence rate: 20-30 per 100000). The Kyoto global consensus report emphasizedthat H. pylori gastritis should be considered the main cause for the development ofgastric cancer. H. pylori treatment guidelines in China, Japan, and South Koreahave recently been revised according to data from each of those countries.However, emerging antibiotic resistance is an important barrier to H. pylorieradication. The recommended H. pylori treatment regimens differ among thosethree East Asian countries. In this review, recent guidelines and up-to-dateresearch on H. pylori treatment regimens from China, Japan, and South Korea arediscussed.展开更多

Though there has been a growing body of literature on regional cooperation between covered countries, Japan and South Korea have been barely discussed. This paper starts with the consensus-based mechanism of a China-Japan-South Korea Free Trade Area (FTA) to probe the approach of its alignment with the BRI in terms of the sequence of “master plans,”“viability of cooperation,” and “embedding of rules.” This inquiry found that the three countries have a shared interest in cooperation in Central Asia to which China prefers a pragmatic approach, while Japan and South Korea an approach combining idealism with pragmatism. Given the huge potential of cooperation between the trio, it is suggested that a “Central Asia chapter” be incorporated in the negotiation framework of this trilateral FTA, and that the design feature three aspects;fundamental principles, specific rules, and an executive body with a view to functionally contributing to regional trade integration in Asia. This approach may also be applied to the alignment of other Asian areas with the BRI.展开更多

A taxonomic comparison was made among strains on the basis of morphological and molecular data. The cellular dimensions of the Chinese Wenling strain (LAMB090508) and Korean strain (PDKS0206) were similar and the cells of both strains were of asymmetric and elongated shape. The posterior end of most cells was rounded. Megacytic zones of aged cells were broader with dense tiny knobs. The roundish nucleus was located in the posterior part of the cell. A few irregular shaped chloroplasts were distributed within the cell. The nucleotide similarity of the two strains, determined from the 5.8S rDNA-ITS sequences, was 99.83%. The comparative results of morphology and molecular analysis suggest that both strains isolated from China and Korea were the identical species, Prorocentrum donghaiense Lu.展开更多

It shows from the analysis and comparison that the floristic relation of East China with Japan is closer than that with northeast China and Korea. The similarity indices of genera and species of seed plants in the two regions are very high, being 72.6% and 43.3% respectively. The structure and species composition of broad-leaval evergreen forests in the two regions are also similar, and there exist many corresponding communities, such as the forests of Castanopsis carlesii and C. sieboldii. Many plants in East China are conspecific with there in Japan, such as Cercidiphyllum japonicum, Magnolia sieboldii, Nandina domestica etc. Though the genera of Ginkgo, Liriodendron, Sassafras etc. existing now in China are extinct from Japan, their fossils have been discovered from the Tertiary strata in Japan. It seems to indicate that the phytogeographical affinities between East China and Japan are closer in ancient the than it is now, and both of the forest floras originated from the same flora. The flora in Japan did not evolve independently until it separated from Chinese continent and drifted northeastwards in the late period of the Tertiary.展开更多

By analyzing these images, we found that the gravity in Liaodong peninsula area showed an obvious increase of 80 × 10^-8ms^-2 during about one- and-half year before the 2011 Japan Mwg. 0 earthquake, and a rapid decrease after the earthquake. This gravity variation is similar to that observed previously for the 1976 Tangshan 1147.8 earthquake.展开更多

The monthly-mean rainfall data observed at 160 stations in China, monthly-mean sea surface temperature(SST) of the Hadley Center for Climate Prediction and Research and monthly-mean air temperature from the NCEP reanalysis during 1960–2011 were used. Correlation analysis indicates that the SSTAs in the Japan Sea in September may last for three or four months and are an important index for forecasting the winter rainfall and air temperature in NE China. Positive SSTAs in the central Japan Sea and in the sea area east of Tokyo correspond to positive rainfall anomaly and negative air temperature anomaly in NE China. With the rise of SST in the Japan Sea, a weak cyclone appears over the Japan Sea. The northeasterly wind transports water vapor from the Okhotsk to NE China, resulting in more rainfall and lower air temperature. Negative SSTA years are accompanied by warmer air temperature and less snow in NE China. The 1000 h Pa geopotential height anomaly and wind anomaly fields are simulated by IAP-9L model, which supports the analysis results.展开更多

In accordance with results of a literature search, review of information disclosed online, and questionnaire survey conducted, the findings of this study are summarized in the following two points: (1) The results show that in Japan most of the home appliances mentioned above have been collected through home appliance recycling tickets, resulting in an issue of "requiring some effort" in treatment and recycling stages, and most plants have contracted out their e-waste recycling; (2) It is found out that advantages of the recycling system in Japan include easiness to monitor concrete data and thorough environmental friendliness ensured while its disadvantages include illegal dumping and export. It becomes apparent that advantages of the recycling system in China include a high reuse rate, low treatment cost, and fewer illegal dumping while its disadvantages include less safe reused products, environmental pollution caused by e-waste treatment, illegal import and difficulty in obtaining data.展开更多

As a result, organic agriculture has emerged. Organic agriculture in South Korea (hereinafter referred as Korea) and China has developed rapidly since the appearance of organic agriculture in 1970s and 1980s respectively. Organic agriculture in China and Korea has developed steadily through agricultural support policies, certification management, institutions construction etc. In the development of organtc agriculture, China and Korea are now facing some technical and extension problems. In general however the development of organic agriculture in China lags behind Korea. China can learn from the experience about the development of organic agriculture in Korea to solve contradiction between development of organic agriculture and food safety, to strengthen the organic food certification, to introduce a system of agricultural direct payment and other positive measures, thus will guarantee steady and healthy development of organic agriculture in China.展开更多

The energy consumption and CO2 intensities for the dominant materials used in buildings are derived from the energy consumption in factories, and the energy consumption to produce equipment is derived from IO (input/output) analysis in order to compare the embodied energy/CO2 for buildings between China and Japan based on the same estimation method. Although the energy consumption of structures in China is two to three times greater than in Japan, the interior finish and air conditioning equipment, for example, are simpler and smaller. As a result, the embodied energy/CO2 of office buildings in China is only 10% to 20% greater than that of Japanese office buildings. Thus, the embodied energy/CO2 of buildings depends on both industrial efficiencies and building design trends of the country.展开更多

Though thegnera Ginkgo, Liriodendron, Sassafixis etc. existing now in China are extinct from Japan, their fossils have been discov-ered from the Tertiary Strata in Japan. It seems to indicate that the Phytogeographical affinities between Japan and E. Chinawas closer in ancient time than it is now; and both of the forest floras originated from one same flora. The flora in Japan did not evolve indepently until it separated from Chinese continent and drifted to northeast in the late period of the Tertiary.

文摘The efficiency of the seaport has been variously studied utilizing either data envelopment analysis( DEA) or stochastic Frontier analysis( SFA). Given the strengths and weaknesses associated with these two approaches, applying both models to compute efficiency estimates for the 11 seaports of the China and Korea from 2012-2016 and comparing the results obtained. Main finding facts of this paper are as follows:( i) there are some differences among relative efficiency levels,but almost no differences among efficiency ranks in DEA and SFA results.( ii) The tendency of VRS is stronger in Chinese coastal seaports during the past several years.( iii) The values among seaports in SFA model are relatively smaller than those in the DEA models. The results show that the efficiency of major seaports in Korea is far lower than that of ports in China.

文摘China and South Korea are the main producers and exporters of ginseng. This paper mainly discusses the characteristics of ginseng price fluctuations in China and South Korea. As people continue to understand the concept of homology of medicine and food,there is still an increasing international demand for ginseng,and the favorable market can be expected.
文摘China is facing the challenge of many marine environment problems with rapid economic growth. Japan had experienced similar marine environmental pressure during its industrialization and had been facing the problem through successful environment policy step by step. The paper reviews the lessons and experiences of Japan’s marine environment protection and analyzes the marine environment pollution in China and its causes, taking Shandong province as a case, such as GDP-oriented economic growth, heavy coal assumption, etc. The paper also analyzes the marine industry with focuses on coastal tourism and its relationship with marine environment. Suggestions on polices are provided based on the analysis on China’ marine environment and Japan’s experience.

文摘The embodied energy/CO2 of buildings in China and Japan, which reflects the characteristic industrial efficiency ofbui|ding materials, is described in this paper. The energy consumption and CO2 intensities for the dominant materials used in buildings are derived from the energy consumption in factories, and the energy consumption to produce equipment is derived from IO (input/output) analysis in order to compare the embodied energy/CO2 for buildings between China and Japan based on the same estimation method. Although the energy consumption of structures in China is two to three times greater than in Japan, the interior finish and air conditioning equipment, for example, are simpler and smaller. As a result, the embodied energy/CO2 of office buildings in China is only 10% to 20% greater than that of Japanese office buildings. Thus, the embodied energy/CO2 of buildings depends on both industrial efficiencies and building design trends of the country.
文摘China has abundant wind energy resources and huge development potential among developing countries.Japan is a developed country that planned to increase the use of renewable energy,especially wind energy.This research is aimed at reviewing the development of wind power and relevant policies between China and Japan.Firstly,we introduced the current status of global wind power development,such as the global installed capacity of wind power.The annual development of wind power generation in China and Japan is compared,and the distribution characteristics of wind resources are compared.Furthermore,the market share in China and Japan is introduced.Finally,according to the comparison of the government policies between China and Japan,we pointed out the existing problems in the wind power industry.In addition,we gave some suggestions on the development of wind power for China and Japan.These suggestions should be taken into account when designing national climate policies and have an important reference value for the future development of China’s wind energy industry.
