Both empirical and theoretical literature on intra-industry trade have developed rapidly. During the past decade, there has been growing interest in the phenomenon of intra-industry trade(IIT), whereby countries export to each other hoods which are broadly similar in nature, or even identical. IIT occurs when countries simultaneously export andimport goods produced by thesame industries or adjacent countries. This phenomenon is not envisaged by the standard comparative advantage theory of international trade and requires explanations based upon factors such as economies of scale, product differentiation, imperfect markets and consumer's taste for variety, which arenot condidered in theworld of perfect competition of the standard theory. This intra-industry trade will certainly occur when the economies are absolutely identical in all respects and can persist under conditions of comparative advantage. However, asufficiently great difference incomparative advantage,either becauseof technological or factor endowment differences,can eliminate thetwo-way trade in manufactures. Thus, intra-industry trade not only may occur between similar economies, it is most likely to occur between such economies and the volume may be much higher than trade based on comparative advantage. If exports and imports tend to match each other in each industry, the index approaches zero. According to Balassa, this signifies a low degree of inter-industry specialization(with a correspondingly high degree of intra-industry specialization). On the other hand, if exports and imports differ widely, theindex approaches unity, indicating high inter-industry specialization(and low intra-industry specialization). This paper explains the analysis of intra-industry trade between Korea and Japan. The verified results of the important contents with respect to thepromotion of intra-industry trade between Korea and Japan and their indications can be summarized as follows. The fact that intra-industry trade between Korea and Japan was unable to take root is attributable to not only to thedifferences in the pattern of economic development and industrial structure, but also to thelack of opportunities for international industrial cooperation. However, Japan is now showingsigns of expanding intra-industry trade to offset the weakening price ocmpetitiveness of Japanese products resulting from thestrong yen and the collapse of thebubble economy. An expansion of intra-industry trade among adjacent countries enables the countries concerned to make full use of the complementary nature of each other's comparative advantage. Under these circumstances, it is becoming increasingly important to find ways to expandtheintra-industry trade between Korea and Japan. To this end, the following steps must be taken; First, Korea should focus on import substitution by stepping up technological cooperation and strategic alliance with Japan in the supporting industry, a field in which Korea is at a comparative disadvantage. Second, Korea should pursue intra-industry trade that relies on product differentiation, especially in the high value-added industries. It must also diversify its export items and promote industries of high income elasticity as major export industries. Third, Inter-Industry Trade of progress of work should be expanded in the manufacturing of machinery and transportation equipment as well as electrical machinery or appliances that rely heavily on trade nad economies of scale. Fourth, in order to make use of Japan's competitive advantage in high developed industries, Korea should utilize to a variety of measures including the use of Japanese techincians, the joint development of technology, and strategic alliance. Fifth, in order to facilitate industrial coordination between Korea and Japan in the information age,, an information and telecommunications network should be established between the two countries. Through this network, the two nations will be able to exchange precise information oneach other's industries of comparative advantage and disadvantage. This inturn, will lay the basis for establishing appropriate strategies for technology development and industrial restructuring with regard to intra-industry trade. For industries where domestic production is possible, inter progress of work should be promoted within the industry. For industries where low technological standards hinder product differentiation, interm progress of work should be promoted within the firm.

The considerable determination for the immunologic assay of human chorionic gonadotropin was reported since Liepmann (1903). Most of all, the purified antigen has been needed for thtis assay. We have used the commercial pure antigens which was confirmed minimal level of sensitivity in antigen, namely 3,500 I.U. in Gravindex (made in Ortho diagnostic.), 2,500 I.U. in Pregnosticon plano (made in Organon inc.), 1,500 I.U. in Pregnosticon All-in (made in Organon inc.). For these immunologic determination of 24 hour urinary H.C.G. in normal pregnancy, threatened abortion and trophoblastic diseases, semiquantitative and quantitative assays have been performed using latex inhibition slide test (Gravindex test, Pregnosticon plano test) and hemagglutination inhibition tube test (Pregnosticon All-in test).

Botrytis cinerea에 의한 들깨 잿빛곰팡이병의 생물학적 방제를 위해 선발한 Bacillus lirheniformis Nl 글주를 제제화하여 미생물농약을 제조하고 이의 방제 효과를 검정하였다. Nl균주의 길항력에 미치는 탄소원과 질소원의 영향을 실험한 결과 탄소원으로는 glucose, 질소원으로는 tryptone이 가장 높은 효과를 보였다. 또한 Nl 균주를 이들 glucose와 tryptone을 첨가한 NB배지에 대량배양하고 그 배양액에 콩가루, 쌀가루, glucose, FeSo$_4$~7$H_2O$ 및 MnCl$_2$. 4$H_2O$ 을 첨가하여 수화형 미생물농약 Soy제제로제조하고,이 병원균에 대한 방제효과를 하우스내에서 폿트 검정한 결과 방제가가 93.1%로서 유의성은 없으나 베노밀 수화제에 의한 86.1%보다 높았다. An antagonistic bacteria, Bacillus licheniformis Nl strain which effectively inhibited mycelial growth of gray mold rot pathogen, Botrytis cinerea was isolated from the rhizosphere of perilla crop. Powder soy formulation by B. lichentfomis Nl strain as a biocontrol agent was developed far the first time and estimated its control effect on perilla leaves in this study. First of all, far the mass production of antifungal metabolites of B. lichentfomis Nl strain in flask liquid culture, the most effective carbon and nitrogen source were selected as glucose and tryp-tone, respectively, For the formulation, vegetative biomass of B. licheniformis Nl strain from 5-day-old liquid culture in nutrient broth added glucose and tryptone was mixed with soy flour, rice flour glucose, FeSo$_4$~7$H_2O$, and MnCl$_2$. 4$H_2O$, and dried and pulverized. In plastic house test, powder soy formulation effectually controlled gray mold rot as the control value of 93.1 %, was more effective than chemical fungicide, benomyl showing the control value of 86.1%. Thus, development of powder soy formulation of B. lichentfomis Nl will aid large-scale application of biological control in field trials.
