The object of this study is to predict the import demands for korean textile, textile products and clothing products. The analyzing method performs through demand prediction method is by using Exponential Smoothing Model and STATGRAPHICS. The result from the practice of study is as follows ; Textile import ratio is expected to be increased constantly and the portion of textile import in our national total import is precited to reach to 3.92% in 2003. The import of the textile product to textile will be increased to 33.12% in 2003. The import ratio of clothing product ratio is also estimated to increase annually, Import ratio of clothing-product in textile-product import reaching to total 6.42% (83.89% in 2000, 90.31% in 2003), the growth rate of clothing import will be much higher than that of clothing export. From 2000 to 2003 , textile import is precited to be 5.23%. The import of the textile product will be increased by 8.04%. The import of clothing product will reaches 11.21%, which would be the highest rate among the products under review. Also , it predicts the constant increase as a result of prediction in the nation's total amount of import including the import amount of textile, textile-product, and clothing product.

This study concerns the export-import demands for Korean textile, textile products and clothing products. The result from the practice of study is as follows ; it predicts the constant increase as a result of prediction in the nation's total amount of export-import including the export-import amount of textile, textile-product, and clothing product. It is estimated that nation's textile trade balance will be about U $ 13 billion of trade surplus in every year from 2000 to 2003. Other hand, the trade balance of textile product is predicted about U $ 1.39 billion surplus, so is clothing product about U $ 3.29 billion surplus. Textile ratio is presumed to gradually decrease in aspect of export. Also, the portion of textile export in our national total export is predicted to reduce to 11.61% in the 2003. On the other hand, Textile import ratio will be constantly increased and the portion of textile import in our national total import is predicted to reach to 3.92% in 2003. Textile-product ratio is also estimated to increase in the area of export & 33.12% in 2003. Clothing product ratio is also estimated to increase annually. What with increasing ratio of clothing-product export in textile-product export reaching to total 0.87% within for 4 years(62.96% in 2003, 63.83% in 2003) and what with increasing ratio of clothing-product import in textile-product import reaching to total 6.42%(83.89% in 2000, 90.31% in 2003), it can be said that increase of its import will be much higher than that of export.

The objective of this study is to know market structures of softwood logs being imported to South Korea from log producing countries. Import demand of softwood logs imported to South Korea from America, New Zealand and Chile is fixed as a function of log prices, the lagged dependent variable and output. On the basis of the adaptive expectations model, linear regression models that the explanatory variables included and the lagged dependent variable were estimated by Seemingly Unrelated Regression Equations (SURE). The short-run and long-run own price elasticity of America's softwood log import demand is -1.738 and -4.250 respectively. Then long-run elasticity is much higher than short-run elasticity. Short-run and long-run crosselasticity of New Zealand's softwood log import demand with respect to American's softwood log import price are inelastic at 0.505 and 0.883 respectively. Short-run and long-run cross-elasticity of Chile's softwood log import demands with respect to American's softwood log import prices were highly elastic at 2.442 and 4.462 respectively. Long-run elasticity was almost twice as high as short-run elasticity.

In this paper, Secant method is proposed to solve multi area economic dispatch (MAED) problem. Generator limits of all generators in each area are calculated at given area power demands plus export (or import) using secant method and the generator limits of all generators are modified as modified generator limits. Central economic dispatch (CED) problem is used to determine the output powers of all generators. Here, Secant method is applied to solve the CED problem. The proposed approach has been tested on two-area (two generators in each area) system and four-area (four generators in each area) system. It is observed from various cases that the proposed approach provides optimally best solution in terms of cost with tie line loss with less computational burden.

Domestic industry has a long history, but it has been suffering for a long time due to its poor competitiveness in management ability, supply of materials, technological development, sales marketing, and distribution networks. Moreover, the industry has not established its strong presence in the world market but is exposed to increasingly greater agonies because of inactive domestic demands, increase rate of import versus export, diversified government policies, and non-selective introduction of high-quality and low-priced foreign named brands of ceramics into the country. Theses factors have partly contributed to consumers' low or negative recognition.

점차 대중화의 추세로 나아가는 골프인구의 증가와 함께 골프카의 수요가 증대되고 있다. 그러나 국내의 골프카 산업은 이러한 시장의 니즈에 적절하게 대응할 만큼 성숙되어 있지못한 상태에 있다. 국내시장의 수요는 대부분 고가의 수입 골프카가 담당하고 있으며 애프터 서비스의 불리함과 부품가격에 있어서도 역시 고가임에도 불구하고 점점 그 수요의 폭이 상승하는 추세이다. 우리나라는 자동차 산업의 기반여건이 제대로 갖추어져 있으므로 골프카 부문에 있어서도 경쟁력 있는 한국형 고유모델을 개발하기에 적절한 시기에 도달하였다고 판단된다. 이에 본 연구를 통하여 국내외 골프카 산업의 현황과 경쟁이 예상되는 골프카를 분석하고 국내여건에 적합하며 향후 해외시장에서도 경쟁력을 갖출 수 있는 고유모델의 디자인개발을 위한 전제조건들을 도출하고자 한다.

Using a multi-variable linear regression technique and SUR(seemingly unrelated regression) model, the demand functions of tractor, combine and rice transplanter were estimated. The demand was regarded as an annual supply of each machine and modeled as a function of 11 independent variables which reflect the actual farmer's income, actual prices of farm machines, previous supply, previous stock, actual amount of available subsidy, actual amount of available loan, arable land, import of farm machines and rice price. The actual amount of available loan affects most significantly the demand functions. The actual farmer's income, actual farmer's asset, loan coverage, and rice price affect the demand positively while prices of farm machines and import negatively. The annual demands of tractor, combine and rice transplanter estimated using the demand functions were also presented over the next 4 years.

The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.

미국 쇠고기 수입 재개 결정으로 발생한 광우병 논란은 기술위험 관리의 차원에서 볼 때 중요한 사례라고 할 수 있다. 광우병은 새로운 수입 조건하에서 충분히 통제될 수 있으며 감내할 만한 수준이라는 정부의 거듭된 주장에도 불구하고 심각한 위험으로 인식하는 국민들은 수입조건의 재협상을 요구하면서 격렬한 대립이 초래되었다. 예방이나 치료법이 없으며 치사율도 매우 높기 때문에 심각한 위험으로 인식될 가능성이 높은 상황에서 내려진 비일관적 결정이 문제 발생의 원인이었다. 또 정부와 관련 제도에 대한 신뢰의 부족도 정부의 결정을 수용할 수 없는 중요한 조건이었다. 그 결과 국민적 저항이 확산되고 이명박 정부의 위기로까지 이어졌다. 이명박 정부의 주장처럼 위험문제의 정치화는 회피되어야할 것이 아니라 오히려 공개적인 토론과 타협을 요구한다. 새로운 유형의 기술위험이 지속적으로 등장하고 있으며 이러한 논란이 되풀이 될 가능성도 있다는 점에서 기술위험 관리에 대한 새로운 접근과 대응이 필요하다. 광우병 논란은 기술위험 관리의 실패라는 점에서 위험관리에 많은 함의를 제공해 주고 있다.
