This study aims to come up with effective counterㆍplans for food safety while the food trade between Korea and China significantly increases and a lot of foods which cause a risk to food safety are imported. The focus of the study is to examine how legislative and administrative management is performed and to see what systems are in place for ensuring food safety. The major findings are as follows:The first is that food sanitation and safety management is incomplete and insufficient,while the Chinese food industry develops very rapidly. Various countermeasures should be established for the health of Korean because a lot of Chinese foods are imported to this country. Lastly, Korea needs to enforce the Beforehand Verification Registration System and the International Certification System quickly. These systems are concerned with the increasing food trade between Korea and China, the imperfect food safety management in China, and the safety management of mass imported foods in both the U.S. and Japan. In conclusion, an effective food safety management system that overcomes the issues mentioned in this study and adheres to safety management standards should be established in Korea immediately. As far as other countries are concerned, China needs to implement the Beforehand Verification Registration System and the Beforehand Certification System in order to ensure its own food safety management effective in the future.

BiSI, BiSI : Co, BiSeI 및 BiSeI : Co 단결정을 고순도의 성분원소와 8.6mole% 과잉의 Iodine를 투명석영관내에 넣고 진공봉입하여 합성한 ingot를 사용하여 수직 Bridgman 방법으로 성장시켰다. 성장된 단결정은 orthorhombic 구조였고, energy band 구 조는 간접전이형으로 293K에서 광학적 energy gap은 각각 1.590eV, 1.412eV, 1.282eV 및 1.249eV로 주어지며, energy gap의 온도의존성은 Varshni 방정식으로 잘 표현된다. Cobalt 를 첨가할 때 나타나는 불순물 광흡수 peak는 Td symmetry점에 위치한 Co2+, Co3+ ion의 energy 준위들 사이의 전자전이에 의해서 나타난다.

This paper investigates, first of all, the recent trend of the agricultural product trade among Korea, China, and Japan. Then, each country`s trade competitivenss is also investigated in terms of three dimensions, that is, productivity, price, and trade performance. According to this research, the productivity of China has increased at the fastest speed, though the productivity of the remaining two countries has also increased. Except the productivity of land, because productivity was calculated as the output per factor input, Japan had the highest productivity based on the absolute amount: China had the lowest while Korea stood in the middle. The price comparison of 27 agricultural products between Korea and China revealed that Korea had 6.1 times as high price level as China. Such a big difference in price level suggests that, in spite of potential tariff and non-tariff barriers, the size of trade between these two countries may increase significantly in the future. Of course, the potential direction of trade would be the export from China to Korea and Japan. Such results were also confirmed in the analysis of trade performance in which TII and RCA were used. That is, in most agricultural products, China had higher export RCA while Korea and Japan had relatively higher import RCA. The trend which emerged over the past few years also indicates clearly that Korea and Japan will be fewer and fewer competitive items while Chinese agricultural products will replace those of Korea and Japan, leading to increased influence of China in the Northeast Asian agricultural product market.

China is absolutely short of water, where per capita water supply is just one-fourth of world average. Currently, over one-half of the major cities have to tolerate water shortage, to a certain extent, and that water shortage is making the deserts in Northwest China wider and wider at a very fast speed. Examination of average water quality of all the rivers in China indicates that, while as much as 21.3% belong to fifth class or lower, just 5.1% belong to first class, suggesting the level of water pollution is very high. The emissions of water pollutants in China is comparable to the sum of those in 2nd through 5th largest countries in the world. Clearly, most of the indices related to the usage of water resources in China are not promising. Then, is there any room for those bad conditions to be improved? According to a forecast for supply and demand of water resources until 2050, per capita water supply is going to decrease. As China pursues high economic growth, the extent of water shortage is expected to become more serious. Recognizing such a problem, Chinese government has employed mandatory water-saving policy. Also, Chinese government promotes a large 'Northen Usage of Southern Water' project so that extra water in Changjiang area can flow to, and be used in, Huanghe area. Despite of some tight governmental policies to preserve water resources, it seems less likely that the current condition of water resources supply and demand will be significantly improved within near future. Today, the policy issue of water resources usage, management, and policy, is so important that it does not belong anymore to the realm of individual areas or countries alone. That is why it is getting global attention. More than any other countries in the world, Korea is affected, due to the geographic location, directly by the results of Chinese water usage and management. For that reason, mutual cooperation between China and Korea is needed indeed to protect the environments of Northeast Asia and the remaining part of the world, as well.
