We analyse benefits and costs of investment on the assurance of aircraft design and development of related infrastructure. Although the discounted cash flow from the sales of aircrafts is found to be smaller than the amount of required investment, the net present value considering the effects of export increase, import substitution, and the accident cost reduction is very high. This justifies governmental investment, for the effects are not easily appropriated by private investors.

The comparative effects of ethylene oxide(EO) fumigation and gamma irradiation (5 kGy) were determined on the chemical components of exportable ginseng-leaf tea which is required for improving the hygienic quality. Saponins and fatty acids detected in the samples were found to be resistant to both treatments at the practical levels. In an experiment on free sugar and amino acids, however, quantitative analysis has shown that glucose, lysine and histidine in the samples are significantly decreased by EO fumigation (p<0.05) and that negligible changes were observed in gamma-irradiated samples.

Masan Port, which is a main entrance to Korea, has undergone the tough time these days. Many problems are mainly due to the deterioration of harbor facilities, the shortage of waterfront area and the decrease of the trading volumes. Especially the trading volumes are seriously affected by the Busan New Port, which was not only very close to the Masan Port but constructed in a large scale. For the Masan Port to develop continuously, therefore, it is vital to modernize harbor facilities, redevelop the old harbor, expand its waterfront, construct green port and develop harbor for sightseeing. At the same time, Masan port should be ready to develop a higher value added port. To vitalize Masan port's economy, we have to push forward a differentiation strategy that makes Masan port specialized harbor for distributing goods like hard and heavy cargo.

In order to study the addition effect of Leuconostoc mesenteroides and nisin on Escherichia coli and lactic acid bacteria during fermentation and storage of Kimchi, Kimchi was stored at 4$^{\circ}C$ for 7 days and then in-creased the temperature to $25^{\circ}C$. Lactic acid content on Kimchi fermentation at 4$^{\circ}C$ was maintained initial content which was increased upto 0.9% and lactic bacteria was also increased after switching to $25^{\circ}C$. E. coli, on the other hand, was a little decreased from the initial level, but a significant decrease was found for the those Kimchi of Leuconostoc muenteroides added and nisin treated group when the fermentation temperature was switched to $25^{\circ}C$.

Gate operations are very important as they are the starting point for export containers and the end point for import containers as far as checking and control exercised by terminal operators are concerned. The objective of this paper is to propose the design of separated gate system in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. Because of a lot of container load and unload within short term, many trucks have to pass the gate at a time. This study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

In this study, consumption-based greenhouse gas emissions from 1990 to 2021 are calculated by the industry sector, and greenhouse gas emissions transferred due to trade between countries are compared to analyze what implications Korea has. As a result, production-based and consumption-based emissions in the United States, Germany, the EU, and the OECD are gradually decreasing. Production-based emission in Korea is larger than consumption-based emissions because Korean economic structure is import-oriented. However, unlike other developed countries, Korea cannot trade energy by land, so it can be said that it is reasonable to establish a greenhouse gas reduction plan considering Korea's unique characteristics.

The Korean silk industry is facing challenges due to decreasing demand and intensified competition. To understand its current state and evaluate its competitiveness precisely, we have visited most of the leading silk firms in Jinju area. By questionnaire and in-depth interview, we investigated their operational problems. We found that most of the managers are understanding the necessity of the capabilities in design and material development, but they did not fully aware of the importance of operational flexibilities. Based on the results of the survey, suggestions that are necessary to restore the competitiveness of the Korean silk industry were proposed from industrial and corporate viewpoints.

Since the OPRC-HNS Protocol entered into forced in the June of 2007, the potential effects on industrial circles are encouraged to be analyzed according to the obligatory regulations listed in the Protocols. This study was conducted on the quantitative analysis of the possible effect on the industrial circles if Korea accedes to OPRC-HNS Protocol. In spite of any burdens caused by keeping "accident emergency program memorandum" and performing "education and any training program for the crews", potential decrease of insurance fee is in possibility provided it follows. In addition, the oil refinery and petrochemical industries may also have burdens for potential costs for acquiring any materials including equipments and fees for education and training related to HNS. However, minimizing any costs by swift response against accidents would be big advantage that comes with paying of small amounts of expense by international convention related to HNS.

This study was carried out to forecast long-term supply and demand of chestnut and to analyze the impacts of change in the environment of domestic and international chestnut markets. For these ends, the study developed a partial equilibrium market model, in which in-shelled chestnut market was vertically linked to shelled chestnut market. To examine the predictive ability of the model for the endogenous variables ex-post simulation was run for the period 1990 through 2003. In general, all endogenous variables reproduced the historical trends during the period except for disuse areas and newly established areas. The results of forecasting supply and demand show that domestic in-shelled chestnut production is estimated to decrease slightly from 76,447 ton in 2005 to 76,286 ton in 2020 and that exports of shelled chestnut continue to be decreased.

The end of cold war and the trend of the detente brought about many changes in the military security policy and in the munitions industry of the West-Europe : reduction of the defence budget, diminution of the military power force and armaments, decrease of the exportation and the domestic demand of ordnance, and augmentation of discharged laborers. This mutation caused the munitions industry and the war industrials regions to a crisis. The munition industrials enterprises which was confronted a crisis searched for diverse strategies like an reconversion to the civil products, an internal diversification and an external growth. And the European Union, the national government, and local or regional self-government implemented policies for diversification of regional economic with an reconversion in order to minimize the effect of the regional economic and society from the crisis of the munition industry.
