  • The trajectory analysis of boundary layer ozone data at four regional sites in the East Asian outflow regions in Japan was carried out together with boundary layer ozone data observed at Mt. Tai and Mt. Huang in the source region of central eastern China during the monsoon onset in May-June 2003 and 2004. At all sites, the influences of anthropogenic emissions from East Asia have been found. During May and June 2004, the evidences of direct pollution transport from central eastern China to Hedo, an outflow site in Okinawa Island were observed. Ozone mixing ratios associated with air masses from central eastern China averaged 45 ppb while those associated with clean air masses from the Pacific were only 14 ppb, which resulted in averaged 31 ppb increase of ozone mixing ratios during the pollution episodes from central eastern China at Cape Hedo. Using transport time analysis and averaging all ozone episodes transported from central eastern China, the ozone dilution rate of 5.4 ppb per day was roughly estimated during air masses transported from source to outflow regions at Hedo. In the regions nearby Japanese mainland, however ozone increases by long-range transports were more related to both domestic and East Asian sources as a whole.

  • Over the past-decade of reform and opening up to the outside world, China#s GNP doubled which now ranks eighth in the world, making an average 9.6% increase annually. Some industrial products such as steel, crude oil and power generation rank fourth in the world, while output of coal and cement rank first. In the agricultural sector, China ranks first in the output of grain, cotton, meat and basically solved the problem of providing food and daily necessities for 22% of the world#s population, The Chinese government has set the objectives in environmental protection plan to be achieved by the year 2000 together with ecological protection. During the Seventh Pive-Year Plan(1985-90), Chains#s annual investment in controlling environment pollution was about 10 billion Yuan, or 0.7% of her GNP, while during the Eighth Five-Year Plan, effort will be made to increase such investments, in terms of the GNP, possibly to 0.85"1% . However, the expanding development including industrial production will increase large amounts of pollutants into the environment and efforts are underway to deal with these pollution. *대한위생학회장 Regional community are faced with serious environmental problems. For instance, so called# Yellow Sand Storm# from China is one of the case. Recently, to make matter worse, acid rain and dry depositation from transboundary air pollution is tend to increase mainly because of emissions from mainland China. Therefore, the countries concerned in the region, should seek to promote international cooperation on environmental issues. An overall aspects of development and environmental programs in China are presented.

  • Charter flight in international air law has, from very beginning, not precisely defined by the International Civil Aviation Organization (lCAO) since 1947 when it came into being. By practice, the operation of charter traffic is, in its very beginning, the subject to the regulations of national rules and bilateral charter agreements (charter annex clause) within the framework of normal bilateral agreement of international air services. Taiwan had signed a series of bilateral air service agreement under the name of the Government of the Republic of China when Taiwan was recognized by the United Nations and major members of international community as the sole legal government representing China before 1971, but that situation was changed since then. Taiwan has only maintained diplomatic relations with 25 States, but maintained semi-official relations with major powers of the world. The former agreements were signed within the framework of the Vienna Convention on the Law of Treaties of 1969 while the latter agreements were signed within the framework of administrative and civil law of two countries which were not in the form of bilateral treaty signed by two sovereign States in its proper sense of international law. The legal regime of charter flights between Taiwan and Mainland China is regulated by special arrangements negotiated by delegated airlines and airlines association or private law institutions.

  • Researches based on the pattern of planned behavior holds that the three variables of entrepreneurial attitudes, subjective norms, and perceived behavior control influence each other and influence entrepreneurial intentions respectively. However, there are also different, even conflicting research conclusions that continue to emerge. Researches based on the pattern of alertness, believe that profit opportunities and individuals' pursuit to truth are the driving forces. Many scholars have demonstrated the impact of individual entrepreneurial alertness on entrepreneurial intentions. However, as an exogenous causal agent, profit opportunities have a logical problem: if there are no other assumptions, the mere existence of opportunities does not adequately explain entrepreneurial alertness. To address this gap, this study considered samples from mainland China, where entrepreneurial activities are very active currently, to test the role that entrepreneurial alertness is assumed to play in the planned behavior model. The results show that the three dimensions of alertness, individually partly intermediate the influence of entrepreneurial attitude on entrepreneurial intention, the influence of subjective norms on entrepreneurial intention, and that of perceived behavior control on entrepreneurial intention. This article studied the production of entrepreneurial intention by integrating the two patterns of planned behavior and alertness through empirical analysis, and opened up a new field for subsequent research on entrepreneurial intention.

  • The goals of this paper are to analyze the present status of logistics on the Dongbei area in China and present implications to the related Korean companies. The mainland of China is very huge, we need to study each regional logistics of China separately. The Dongbei area is more than three times as much as the Korean peninsula, and the population is over two times as much as the two Koreas. Therefore, Korea which is trying to be a logistics hub in Northeast Asia has to pay attention to the logistics of China. This study tries to analyze the logistics of the Dongbei area, but except for the Liaoning province, we needs more information.

  • We review the research literature on relationship between environmental regulation and industrial development in three aspects of environmental regulation and investment, environmental regulation and efficiency, environmental regulation and trade. Indeed, the linkage between environmental regulation and material consumption of industrial system is absent. Environmental regulation is measured as the expenditure share for industrial pollutants abatement, and effluent charge intensity. Using panel-level data from 31 provinces, municipalities and autonomous regions in China, we build correlation models between material consumption and environmental regulation, results show that: (1) there are significant quadratic function relationship between material consumption and environmental regulation. And there is the fact that inflection point exists. (2) On basis of inflection points, we make two remarkable reflections. Firstly, the inflection points are the most important scale to judge reasonability and performance of regulations. Secondly, a Pareto improvement may occur when the regulations achieve a certain target. (3) Both intensities of industrial pollutants abatement expenditure and effluent charge have not yet achieved the expected target in most regions of mainland China at present. And most of regions of material consumption decreasing are distributed in western China. Main reasons lie in the impacts of industrial features as well as the regulations.

  • Human diphyllobothriasis is a widespread fish-borne zoonosis caused by the infection with broad tapeworms belonging to the genus Diphyllobothrium. In mainland China, so far 20 human cases of Diphyllobothrium infections have been reported, and the etiologic species were identified as D. latum and D. nihonkaiense based on morphological characteristics or molecular analysis. In the present study, proglottids of diphyllobothriid tapeworms from 3 human cases that occurred in Heilongjiang Province, China were identified as D. nihonkaiense by sequencing mitochondrial cytochrome c oxidase subunit I (cox1) and NADH dehydrogenase subunit 5 (nad5) genes. Two different cox1 gene sequences were obtained. One sequence showed 100% homology with those from humans in Japan. The remaining cox1 gene sequence and 2 different nad5 gene sequences obtained were not described previously, and might reflect endemic genetic characterizations. D. nihonkaiense might also be a major causative species of human diphyllobothriasis in China. Meanwhile, the finding of the first pediatric case of D. nihonkaiense infection in China suggests that infants infected with D. nihonkaiense should not be ignored.
