The construction of Jeju Naval Base was finally completed and donated to the Republic of Korea Navy on February 26th this year. There is no doubt that the new base will contribute to the substantial augmentation of Korea's naval power and maritime security. However, we should note that the new naval base took a long and hard twenty-three years to be completed. In the 21st century, Korea should adopt a new strategy that can fulfill the security requirements of Korea for the new age of international relations. The 21st century is characterized by globalization, and in the world of globalization, a national boarder has become meaningless. In the late 20th century, after the Cold War, trade between countries have greatly increased and so did the importance of the seas. Having transformed from an agricultural country into a commercial country, Korea went from a continental state to a maritime state. Korea has become the 9th largest trading state, and obviously, the importance of the sea has become significant. Korea's national strategic focus needs to be on the sea for national survival. Thus, since the 1990s, the Korean Navy has planned to build the Jeju Naval Base. Jeju, due to its geopolitical characteristics, is extremely important to the 21st century Korea's economy and national security. Jeju is the starting point of the sea route that reaches out to the world, and at the same time, the ending point of the sea route that heads towards Korea. Jeju is located in the center of Northeast Asia and thus, Jeju Naval Base is extremely important for the area's security and order. Jeju Naval Base will be very useful not only for the maritime security of Korea, but also for keeping peace and order in Northeast Asia. Jeju Naval Base was the minimal effort against the six sea route security threats towards Korea. The six sea route threats are: 1) Threat from North Korea; 2) China's Threat towards Korea's sovereignty; 3) China's treat towards Korea's fishery; 4) Threat from Japan; 5) Threat towards Korea's sea routes; 6) Threat from recent phenomena of isolationism of the United States. Jeju Naval Base is built for both warships and civilian ships--such as cruise ships--to use. Just like the United States' Pearl Harbor, Jeju Naval Base will become not only the largest military base, but a beautiful tourist site.

This paper presents a method of giving weights to garbage class clustering and Filler model to improve performance of keyword spotting system and a time-saving method of dialogue speech processing system for keyword spotting by calculating keyword transition probability through speech analysis of task domain users. The point of the method is grouping phonemes with phonetic similarities, which is effective in sensing similar phoneme groups rather than individual phonemes, and the paper aims to suggest five groups of phonemes obtained from the analysis of speech sentences in use in Korean morphology and in stock-trading speech processing system. Besides, task-subject Filler model weights are added to the phoneme groups, and keyword transition probability included in consecutive speech sentences is calculated and applied to the system in order to save time for system processing. To evaluate performance of the suggested system, corpus of 4,970 sentences was built to be used in task domains and a test was conducted with subjects of five people in their twenties and thirties. As a result, FOM with the weights on proposed five phoneme groups accounts for 85%, which has better performance than seven phoneme groups of Yapanel [1] with 88.5% and a little bit poorer performance than LVCSR with 89.8%. Even in calculation time, FOM reaches 0.70 seconds than 0.72 of seven phoneme groups. Lastly, it is also confirmed in a time-saving test that time is saved by 0.04 to 0.07 seconds when keyword transition probability is applied.

As the fashion industry comes under the influence of globalization throughout all fields of industry, the globalization and the market entry strategies are required for Korean fashion firms. This study attempted to analyze the factors influencing foreign entry mode of Korean fashion business based on Eclectic Theory. Data collection has been carried out from November 25 until December 25, 2005. The questionnaires were sent through e-mail or fax to 622 trading companies. 67 questionnaires were returned for a response rate of 10.7%. Of these returns, 61 usable questionnaires were employed for data analyses. Descriptive analysis, factor analysis, discriminant analysis, and t-test were used for data analysis. First, the most important venture motivation was price competitiveness and many firms were engaged in both production and sales in their target countries, which were mainly in Southeast Asia. Second, the firm's ability and experience were found out as ownership advantage factor, investment stability and market potential as location advantage factor, and contract stability as internalization advantage factor. Third, the result of discriminant analysis showed that location advantage factor was a significant factor in predicting the entry of fashion firms into foreign countries.

So-Hap-Hyang-Won, a traditional oriental medicine used in the treatment of stroke patients, was examined for its ability to reverse the cell damage caused by lipid peroxidation products and oxidative stress in bovine aortic endothelial cells (BAEC). The effects of herbal medicine on cell proliferation and recovery of oxidative damaged situation were studied in BAEC, which was considered an appropriate in vitro model for stroke resulting from various vascular diseases prevalent in advanced age. In a clinical study of stroke patients, So-Hap-Hyang-Won appeared to improve considerably arm and leg movements as well as consciousness disturbance condition, compared with other traditional medicines used for stroke. When BAEC were treated with extracts of the lyophilized herbal medicines, only that of So-Hap-Hyang-Won stimulated cell proliferation and showed no toxicity even at high concentrations. In studies of BAEC treated with extracts of the lyophilized material of the 14 components of So-Hap-Hyang-Won, only the extract of Foeniculi Fructus stimulated cell growth at all concentrations tested. Moreover, when cells were treated with Foeniculi Fructus (10 and 100 mg/ml) extract after prior exposure to t-BHP ($l0\mu\textrm{M}$) or HNE ($0.2\mu\textrm{M}$), lipid peroxidation products which are known to be involved in aging and vascular diseases, or after the exposure to SIN-l ($500\mu\textrm{M}$), which generates nitric oxide (NO) and other reactive oxygen species, there was substantial recovery from the oxidative damage, presumably due to the radical-scavenging effect of Foeniculi Fructus extract. Foeniculi Fructus not only showed stimulatory effects on cell growth and cell damage repair in BAEC, but also appeared to show the most anti-aging activity among all the herbal components of So-Hap-Hyang-Won.

The projection on the demand for seafarers is seen to continue to rise in consonance with the world's fleet increasing tonnage. It is also expected that recurring officer shortages is paramount when global markets bounce off from the economic downturn it experienced for the last few years. In BIMCO/ISF(The Baltic and International Maritime Conference/International Shipping Federation) report for 2010, a continuous effort to produce competent seafarers should be adapted and as much as possible, reduce the wastage in the industry to address the looming scenario. The Republic of Korea, an OECD member, is a powerhouse in shipbuilding industry and has also had continued to show also an expanding trend in its fleet. On the other hand, the Philippines is still acknowledged as the main source of manpower for ocean-trading vessels. In this paper, a statistical comparison of maritime graduates' career path between the two countries is presented. In conclusion, it is suggested that a mutual co-operation between the Republic of Korea and the Philippines can be established with focusing on international maritime education and training collaboration.

Methane, as a greenhouse gas, is some 21~25 times more detrimental to the environmental than carbon dioxide. Landfills generally constitute the most important anthropogenic source, and methane emission from landfill was estimated as 35~73 Tg per year. Biological approaches using biocover (open system) and biofilter (closed system) can be a promising solution for older and/or smaller landfills where the methane production is too low for energy recovery or flaring and installation of a gas extraction system is inefficient. Methanotrophic bacteria, utilizing methane as a sole carbon and energy source, are responsible for the aerobic degradation (oxidation) of methane in the biological systems. Many bench-scale studies have demonstrated a high oxidation capacity in diverse filter bed materials such as soil, compost, earthworm cast and etc. Compost had been most often employed in the biological systems, and the methane oxidation rates in compost biocovers/boifilters ranged from 50 to $700\;g-CH_4\;m^{-2}\;d^{-1}$. Some preliminary field trials have showed the suitability of biocovers/biofilters for practical application and their satisfactory performance in mitigation methane emissions. Since the reduction of landfill methane emissions has been linked to carbon credits and trading schemes, the verified quantification of mitigated emissions through biocovers/biofilters is very important. Therefore, the assessment of in situ biocovers/biofilters performance should be standardized, and the reliable quantification methods of methane reduction is necessary.

Namhansan fortress of Kwangju in Kyonggi Province has remained a traumatic historical landscape of Manchu invasion in the year 1636. Skirted by the mountain fortress and on the ground of the uplifted flatland was the county seat which was relocated in 16Z7 from Kogol at the underneath ravine and later removed in 1917 to a crossroad place at the low-lying river plain. Once a secluded mountain village, Sungnaedong was at the outset planned as a county town of Kwangju, achieving thereafter a dramatic transformation from a small town of three hundred households into a nascent urban settlement of approximately six hundred households by the mid-18th century. The townscape of Sungnaedong features shrines, a second palace, a magistrate-commander's office, administrative buildings, and a periodic marketplace which were all decreed by the Neo-confucian template of the scheme of county seats. Townspeople managed to live on tilling tax-alleviated crop lands, trading merchandise, and selling their labor. Changing socio-economic situations led to the relocation of the administration center to the gateway village of Jumakri, which consequently heralded the decline of the mountain-fortress settlement of Sansungri at Namhansan.
