The cultivation of Poria cocos on tree-stumps and logs, was first described at the beginning of the 13th century. Poria cocos has been used for medicinal purposes to treat physical and mental recuperation, promote diuresis, forgetfulness and physical weakening. The artificial cultivation techniques of P. cocos was reported in China in 1957. are reported. The basic study on morphological characteristics and artificial cultivation method of Poria cocos with pine tree log buried under ground were initiated by Rural Development Administration. To widen the utilization of harvested sclerotia of Poria cocos as new food stuffs, powder of the sclerotia were used for producing new soft drinks and supplemented to wheat flour to make functional bread. Last 30 years, the supply of P. cocos in Korea through cultivation could not meet the domestic demand, Korea collected P. cocos in the mountainous areas and also import the sclerotia from China. Since the domestic demand of the sclerotia in China increased, the price of imported sclerotia of P. cocos also increased. Recently, high-quality and high-yielding cultivation methods were developed in Gyeongbuk Agricultural Research and Extension Services (GARES). The new cultivation methods of P. cocos developed by GARES was to change traditional cultivation method from under ground to above ground cultivation house, and shortened cultivation period by half, and improved the quality of the sclerotia. Therefore, it is suggested that advanced new technology for production of sclerotia of P. cocos from under ground and above ground must be developed for fullfil the domestic demand of the sclerotia.

This paper is to analyze how firms in a large firm-led industrial city have carried out the restructuring in the face of radical shifts, with focus on the strategy and the restructuring of firms in Ulsan, a typical industrial district in Korea that is specialized in heavy & chemical industry. It has been well known that the local economy has been led by a small number of large firms, including affiliates of chaebol, and its industrial structure has also been characterised as a clear dichotomy between large firms as a customer and small and medium-size firms as a supplier, which can be called not horizontal but vertical relations. It can identify some tendencies, however, that local companies have been rather dynamically changing in response to increasingly turbulent environment since the Asian crisis. Some are radical, but some incremental. These can be summarized in four distinctive but interlinked ways. First, more than half of local companies surveyed have attempted to change their production systems, mainly from the fordist mass production towards the flexible mass production, seeking both economies of scale and scope. Second, local firms have vigorously continued to reorganize the boundary of the production and the organization, by specializing products and focusing on the core competence in order to save costs and cope with radically changing customer demands in a flexible way. Third, there have been various strategies for the organizational innovation such as the introduction of team organization, the boundary blurring between the managerial and production workers and the intra-firm spin-offs, so as to improve managerial efficiency and competence in the use of internal labour market. Finally, they have tried to be more sensitive to the market and customers. These tendencies seem to be increasingly critical to sustain their competitiveness. To do so, they tend to focus increasingly not only on the competing via the product quality rather than through price, but also to seek to diversify the market and customer firms beyond national boundary.

Using a multi-sector dynamic stochastic general equilibrium model, we investigate the dynamic effects of a variety of shocks to a small open economy. In particular, we calibrate the model to match the main characteristics of business cycles in Korea and analyze the effects of external shocks: the terms of trade and world real interest rate shocks. Business cycles in Korea more closely follow those of the G7 countries rather than Asian countries. The simulation results suggest that an improvement in the terms of trade has positive impact on investment, output and consumption, while a decrease in the world interest rate has a significant and positive effect on investment. This paper concludes that external shocks significantly influence business cycle fluctuations in Korea.

Based on previous research for end-users information needs, this research is to investigate DB costing method for decision-making on pricing of DB service by critical factors. The first phase of the research classifies the elements of DB product cost accounting by activities of the circulation system of information in DB service. The second phase is to develop model based on results of DB product costing in the first phase of research. The third phase of research is to present the process of DB product cost accounting by applying the model to an on-line service company. Finally, the research develops the pricing decision model to determine the priority of each factor by survey from major on-line service companies in America and Japan. It is essential to research further regarding the DB product costing and pricing methods in order to determine a proper DB service charge. The right Pricing decision in the DB service charge will contribute to the growth of the DB industry.

Globalisation has intensified the international movement of labour and South Korea is no exception. Korea, which in the past was itself a labour-exporting country, has seen a reversal in human mobility since the late 1990's with a rapid growth in immigration and a transformation of a previously almost ethnically homogenous society. In this context, the important questions about the cultural and political implications associated with the construction of minority representations in the media have remained highly unexplored. The starting point of this study is an examination of the vital role of public service broadcasting (PSB) in Korean society, where ethnic minorities have increasingly become visible. The study shows the significant role of PSB in representing cultural diversity in public debates and the ways in which such representations and their dissemination reflect media power.

Neoliberalism can be seen as a path-dependent, hybrid and contradictory project that operates actually (not just ideologically) through intervention of the state that has been not weakened in its strength but different in its strategies, especially through neoliberal policies of remaking urban space. This paper seeks to characterize the development of neoliberalism and urban policies in S. Korea, by examining the trajectory of neoliberalism generated in its contextually specific way since the late 1980s, by illuminating the intersection between new neoliberal programs and the existing developmentalism of the state and changes in spatial policy with its effects, which can be divided into two phases: the first from the late 1980s to the economic crisis in 1997, and the second from the crisis to the present. This paper finally identifies several paths in which the state and the market would be interrelated, and argues that the vision of national development and spatial policy should be welfare(i.e. human)-oriented, not industry(i.e. capital)-oriented.

The purpose of this paper is to develop an online analytical processing (OLAP) database system for small and medium-sized enterprises (SMEs) growth support. In this paper, we made a model of measuring SME size first. The model is composed of five determinants of firm growth such as employment, sales, the amount of export, own technology, and the ratio of R&D expenditure to sales. Second, we designed the FREQUENCY dimension table which will make staged support of R&D expenditure. We developed the OLAP database system by using three dimensions including the FREQUENCY dimension, and using the model of measuring SME size. Also we assessed past decisions on R&D expenditure support in the Small Business R&D Support Project by using the OLAP database system.

Citric acid is a natural preservative and is used to add a sour taste to foods and soft drinks. For the preparation of stable food additives of citric acid, a coating process using vegetable oil was developed. Coating materials used were purified soy bean oil and carnauba wax. The yield of coated citric acid was up to 95% in both cases. The contents of coating materials was 20~33% in the total composition and the coating efficiency was 95.2 ${\pm}$ 0.01%. The surface of coated citric acid was much smoother and more homogeneous than that of original citric acid according to SEM data. The coated citric acid can be used to as a stable food additive and also would be applied to nutraceuticals and cosmetic ingredients.

Today venture holds highly skilled technical manpower and high-tech products. To maintain the superiority in competition in the market, it is necessary to complete preparations, first of all, the effectual global marketing strategy should take precedence over the others. Therefore, this research is based on the research report of the special feature, the state of affairs and marketing strategy of venture business and is made up the questionnaire to interview total 200 companies of venture that was registered in Dec. 2006 and then is made the analysis of relevance of the statistical data of 154 companies of them and set up a hypothesis. As the result of it, it is set up two hypotheses. One of them is the difference of products, price, distribution and promotion according to the growth period. And the other is the difference of distribution and promotion according to the turnover. The venture places the great deal of weight on the discriminatory products concerned technical development and marketing activity. It is pointed out that it is to be passive to seek a new market promote the products, because of limitations of manpower, funds, technology and information in the beginning with smalt turnover.

This paper is concerned with the effect of an increase in the import price of LNG on the Korean economy and industries. A computable general equilibrium analysis is applied to compute the comparative-statical effect of 10% rise of LNG price. The price increase places relatively heavy burden on the city gas, oil products and thermal power, decreasing their outputs and domestic sales by relatively larger percentages than other industries. The 10% increase in the LNG price reduces GDP by 0.4% and raises the general price level by 0.08%. The increase in oil price resulting in the same decreasing rate of GDP caused by the 10% LNG price rise turns out to raise the general price level and reduce the consumer's welfare in terms of equivalent variation by less percentage than the increase in LNG price.
