The rapid increase in the consumption of products that contain rare metals has highlighted the importance of recycling and recovering resources from these products when they enter the waste stream. Among various metal resources that can be recovered, this study analyzes the waste streams of cobalt and palladium to determine how their waste resource circulation can be improved at each stage of the waste stream. The findings of this study point to improvements and strategies that can be made at individual stages. First, at the discharge/import stage, the implementation of tariff quotas for specific recycled metal resources is suggested to allow the systemic categorization of waste metals as resources. At the collection/discarding stage, a major problem is the instability in the supply of scrap metals, which may be better managed by changing the bidding process for the scrap metals. At the pretreatment stage, possible areas for improvement are uncovered concerning technical areas, such as technological development and improving the efficiency of material recycling, as well as policy-wise, for instance, expanding the regulation for manufacturers to produce products that are designed to facilitate resource recovery, increasing incentive for closed recycling, and refining the guidelines and standards for recycling. At the resource recovery stage, as the waste metal recycling industry consists of businesses that vary in size, policies to promote cooperation and coexistence between large and smaller enterprises will benefit the industry in the long-run. Lastly, at the product production/export stage, a tariff on exporting waste resources that contain cobalt and palladium will help control the amount of waste metals that are shipped abroad.

Environmental tests are used to verify a equipment that can withstand the rigors of harsh environments. In case of military products for export, the tests have to be based on the climatic data of the world. However, if the climatic data of the world is used for domestic military products, it may cause an increase in manufacture price. There is currently no climatic data that can be used as criteria for the tests in the Korean peninsula and coastal seas. Therefore, this paper suggests a water temperature and a salinity guidelines of salt fog tests for military products used in the area. As a result, we present water temperature and salinity information that is extreme and FOO of the Korean coastal seas.

The aim of this study is to investigate the influence of the technological changes on locational changes on the assumption that technological changes cover over all industrial sectors. The study is carred on 1) To investigate the theoretical backgrounds of the technological and locational changes and their problems. 2) To investigate the location and economic characteristics of the Korean textile industry. 3) To investigate the technological development and regional variations in technological level. 4) To the relationship of the technological change to the location of the textile industries. The locational change of the Korean textile industries have been closely related to economic characteristics. In the begining stage of development in the 1950's, thetextile industries were largely concentrated in the major cities(Seoul, Pusan, Taegu, Masan et. al.). In the growing stage of development in the 1960's, the textile industries were relocated in suburban areas with the trend of large corporations building their branch plants of chemical fibers in the suburbs. With the expansion in the export industry in the 1970's, the textile companies were distributed throughout the whole country. But the research and development(R&D) activities caused the textile industries reconcentrate around Seoul and Pusan, owining to the change of the economic environments in the 1980's. The 1980's have witnessed the increased R&D investment for the development of better new and value-added products. This was because the technological level was much higher than that of Taegu and Other regions. What is more, plant birth location and branch plant location support that locational changes of textile industry were caused by technological changes. Plant birth location put stress technological environments of region, compared with branch plant locaiton. Accordingly, the technological changes of industry can be an important factor in locational changes. Through this study, it can be seen that locational changes come from technological changes. Other locational factors influence the industrial locations, but regional variations in technological level which has been relatively ignored has to be considered on the location study. Together with the accomplishments of existing location study, the study on technological change and location can better explain the location phenomena. And further research on technological change and location can provide better policy implications for regional development.

The purpose of this study was to improve the fitness of Korean manufactured apparel products being exported to China and to provide for the basic data useful to the development of a torso prototypes for the Chinese women. For this purpose, Chinese college women aged between 18 and 24 were sampled to test the fitness of the Korean manufactured apparels for the Chinese women sample and address the problems of unfitness and thereupon. The results of this study can be summarized as follows; As a result of testing the fitness of the Korean manufactured apparels for the Chinese women, it was found that Chinese women felt more or less comfortable for the front of the jackets, but felt less comfortable with their side and back. Such a finding suggests that the Chinese women's postures are more turned back than the Korean women's. And also for the slacks, lack of a crotch length causes unnecessary pulls and creases from the back part to the crotch of a pair of slacks and the side line was not suitably placed. For this reason, the differences between the body shapes of Chinese and Korean women should be thoroughly considered when drawing the patterns to export to China.

Antioxidants present in fruits and vegetables have a potential to reduce disease risk, and increase the shelf life of food products by reducing lipid oxidation. The effect of marination with antioxidants-rich fruit juices on quality characteristics of vacuum-packed chicken wings were examined during frozen storage. Chicken wings were mixed separately with marinades containing pineapple juice, June plum juice, and mango juice and kept for 12 h and 24 h. Three best marination conditions were selected based on a sensory evaluation. Antioxidant activity and total phenolic content of fruit juices, and marinade uptake, and marinade loss of marinated chicken wings were determined. In addition, vacuum packed marinated chicken wings were tested for pH, water holding capacity (WHC), 2-thiobarbituric acid reactive substances (TBARS) value and antioxidant activity over a 4-wk frozen storage. The best sensory properties were reported from chicken wings marinated with pineapple juice for 24 h, mango juice for 24 h, and June plum juice for 12 h (p<0.05) compared to other marinade-time combinations. Mango juice showed the highest antioxidant activity (92.2%) and total phenolic content (38.45 ㎍/mL; p<0.05) compared to other fruit juices. The pH and WHC of vacuumpacked chicken wings were slightly decreased over the frozen storage (p<0.05). Moreover, chicken wings marinated with mango juice had the lowest TBARS values and the highest 2,2-diphenyl-1-picryl-hydrazyl-hydrate free radical scavenging activity. In conclusion, mango juice was selected among tested as the most effective marinade for enhancing the oxidative stability of lipid while maintaining the other meat quality traits of vacuum-packed chicken wings.

This paper examines the causes of the terms of trade decline in Korea since the mid-1990s, using the decomposition methodology suggested by Baxter and Kouparitsas (2000) as well as regression analysis. The main empirical results are summarized as follows. The decomposition exercise of changes in terms of trade showed that Korea's terms of trade decline for the past decade or so is attributable to goods price effect which were driven by the rise of oil prices relative to manufactures. The decomposition of terms of trade change for 55 countries showed that terms of trade decline due to goods price effect is a phenomenon that was commonly observed for exporters of manufactures since mid-1990s. These results suggest that external factors such as China's trade expansion, rather than internal factors, are mostly responsible for the decline in terms of trade. In accordance with these results, the regression results suggest that China's trade expansion contributed to Korea's terms of trade decline, especially in 2000s, by raising the import prices of oil and raw materials and lowering the export prices of manufacturing products.

In 1970, direct overseas investment in Korean fisheries started to sell the frozen marine products to Singapore with establishing local subsidiary. Direct overseas investment in China has carried out since Korea and China established diplomat relationship in 1992. the former day, The Korea invested indirectly in China via Hong Kong. It has reported that 253 local subsidiaries applied to China government permit at the end of 2004. The results will make a decision on whether to invest continuously. The results of actual proof analysis has announced that a successful investment of fishery company is mainly influenced in its own government policy. Many advantages of tax and administration for foreign company in China have been changed and vanished comparing to the beginning time of entering china. So. it is imperative for Korean government to take measures to changing policy of Chinese government. The early days, investment of fishery company is type of resources and abundant resources will affect succeeding investment. Nowadays, the type of the investment is the production oriented investment. And then many direct investment linked the production oriented investment have been conducted in many area in China. So. the production oriented investment will affect logistics and successful investment in China. And, The factor of Market potential in Market Factors in the middle of changing market oriented investment will conclude whether to invest. As the china exchange system changed from the fixed exchange system to the fluctuating exchange system. Risk of exchange rate will affect corporate's parent business. The local risk (regulation of import and export, remittance) will affect succeeding investment of corporate's parent.

BACKGROUND: The residue dissipation pattern of pesticides for agricultural products during the pre-harvest period after the final application is important to prevent the maximum residue limit (MRL) violations in domestic and export markets. The MRL violations of carbendazim are observed more often in chamnamul by pesticide residue management surveys by the Ministry of Food and Drug Safety. The residue level at the pre-harvest interval (PHI) and the residue dissipation constant from the critical good agricultural practice (cGAP) trials could be estimated to meet the MRL and pose a health risk to consumers. METHODS AND RESULTS: Chamnamuls were harvested at 0, 1, 3, 5, 7, 10, and 14 days after application of carbendazim in accordance with critical GAP. The residue analysis in chamnanul was performed by HPLC-DAD with the C₁₈ column. The limit of quantitation of carbendazim was 0.04 mg/kg, and the recoveries were 74.4 - 95.8% at the two spiked levels (LOQ and 10LOQ) of carbendazim. The dissipation rates in chamnamul were calculated from the residues at the sampling days by statistical method at a 95% confidence level. The biological half-lives of residual carbendazim in the field trials 1 and 2 were 4.9 and 4.4 days, respectively. CONCLUSION(S): In this dissipation study, the residue concentrations at the recommended PHI were higher than the established MRL in Korea. Therefore, the MRL is proposed based on the residue data sets from the trials conducted at the same cGAP and the dietary exposure assessment.
