This paper considers an (r, Q) policy for operation of a multipurpose facility. It is assumed that whenever the inventory level falls below r, the model starts to produce the fixed amount of Q. The facility can be utilized for extra production during idle periods, that is, when the inventory level is still greater than r right after a main production operation is terminated or an extra production operation is finished. But, whenever the facility is in operation for an extra production, the operation can not be terminated for the main production even though the inventory level falls below r. In the model, the demand for the product is assumed to arrive according to a compound Poisson process and the processing time required to produce a product is assumed to follow an arbitary distribution. Similarly, the orders for the extra production is assumed to accur in a Poisson process are the extra production processing time is assumed to follow an arbitrary distribution. It is further assumed that unsatisfied demands are backordered and the expected comulative amount of demands is less than that of production during each production period. Under a cost structure which includes a setup/ production cost, a linear holding cost, a linear backorder cost, a linear extra production lost sale cost, and a linear extra production profit, an expression for the expected cost per unit time for a given (r, Q) policy is obtained, and using a convex property of the cost function, a procedure to find the optimal (r, Q) policy is presented.

The marine biotechnology industry is very significant as compared to other industries as one of the driving forces for economic growth in the next generation in Korea. However, the marine biotechnology market has been considered as a component of the biotechnology industry market which made difficult for creating separate research areas in relation to the scope of the relevant industry market as well as making it difficult to establish its own R&D policy strategies. Accordingly, this study was executed to estimate the future long-term market value of the marine biotechnology within the limit of industrial field and to verify the importance of national R&D investment in marine biotechnology on the basis of estimations within the industrial perspective. To this end, we classified the marine biotechnology industry into the four sub-sectors and estimated the domestic and global industrial market in 2010 and 2024. According to the results, the domestic and global market of the marine biotechnology industry will see a remarkable growth by 2024. In particular, the bio-energy, pharmaceutical and functional foods industry markets will achieve astonishing advances. On the basis of the analysis results, Korea has to establish more progressive and aggressive R&D investment strategies to strengthen national competitiveness through the marine biotechnology industry.

This paper analyzed the statistical status of public properties, management organization, operational performance focused on Gyeonggido. And This paper tried to get some implications through comparative analysis of public property management system of Gyeonggido and other local governments including Seoul, Incheon. The survey was also conducted on the whole practitioners of public property management in Gyeonggido. As a result of analysis, although Gyeonggido has an urgent need to raise funds because financial independence is insurfficient, non-tax revenues from it's own public properties are insignificant compared to holdings. The major reason would be pointed out that the dedicated management department on public property is not composed and lack of workforce. The survey results conformed that establishment of the dedicated department to public property management is urgent by reorganization of management structure for the higher operational performance.

According to the growing importance of science and technology policy, investment in research and development (R&D) has been increased. In this context, a patent as one of outcome of firm's systematic R&D investment is the way to hold a dominant position in companies' technology competitiveness and also to protect technology right. This study attempts to find the effects of input resources and intellectual property production activity on company value. It conducted empirical analysis based on 238 KOSDAQ-listed and medium-sized firms. Using the previous research, this study configurated research variables about activity of patent production, company value, and input of resources. Through these variables, it aims to know the effect of input of resources and activity of patent production on company value. First, the result of regression analysis shows that R&D cost has the positive effect on a patent production and sales promotion cost positively affects on the registration of the trademark. Second, the output of regression analysis indicates that a patent has the positive effect on company value but a trademark has not. With regard to the input of resources, R&D cost has the influence on company value but sales promotion cost has not. This study attempts to find the effectiveness of company's intellectual property registration on its value and suggests a way that the systematic R&D investment contributes the growth of company value.

It is well known that in the knowledge-based economy a firm's intellectual property including patent is crucial for its competitive advantage. In industrial economy, tangible assets such as land and equipment have been of critical importance for a firm's competitiveness. However, as the paradigm shift to the knowledge-base economy is being accelerated, intangible assets such as intellectual property are considered to be more influential for a firm to be competitive. The valuation of intangible asset is as necessary as that of tangible asset. In particular, reasonably accurate valuation of patent which represents a firm's technological competitiveness seems to be of great importance since (1) it is essential for a firm's patent strategy development, (2) it can activate the technology market, and (3) it is necessary to evaluate a patent's technological contribution when multiple patents are used to develop and commercialize an innovative product. Unlike that of tangible asset, the valuation of intangible asset is very difficult. In order to figure out a value of patent it is necessary to use a number of appropriate valuation factors. In this paper, we surveyed various valuation factors presented by previous researches and several technology valuation organizations to find a set of common valuation factors considered to be of more importance.

Fumigants are used worldwide for control of biological agents that damage wooden cultural property. To establish a policy for fumigant use, biological evaluation of insects and microorganisms considering many factors is required. This study was performed to evaluate biological sensitivity and wood penetration of three fumigants applied for control of biological agents that damage wooden cultural properties in Korea. Among these, methyl bromide and ethylene oxide can control insects and fungi when exposed directly. However, they were unable to completely control biological agents within deeper parts of wood. Ethanedinitrile, which was developed as an alternative fumigant, exhibited outstanding wood penetration and biocidal efficacy. Further research involving various environmental conditions is warranted.
