Recently, the research of the nano technology has been done on a lot of area over the world. Especially, the interest of them is much higher for semiconductor companies and other super accuracy processing area. In this thesis, we have approached the characteristic of the tensile and bonding of copper, frequently used to nano wires, by molecular dynamics simulation. And the simulation was done by EAM, Embedded Atom Method which has the most highest accuracy for metal. Then the feature of copper at atom space is understood through the simulation of nano wire.

Water-soluble chitosan and water-insoluble chitosan with molecular weight of 2,000,000, 500,000, 80,000, and 40,000 and more than 90% degree of deacetylation were controlled to evaluate the antibacterial activity of chitosan against a pathogenic bacteria, methicillin resistant Staphylococcus aureus(MRSA), which is being issued in the world. The Shake Flask Method and Modified Shake Flask Method were used to find out the antibacterial activities of 5types of chitosan/acetic acid solution, and the other antibacterial activities test with the cotton filter treated with chitosan /acetic acid solution. Those test methods showed the great differences ,but the results of the antibacterial activites showed the same difference.

To study marketing strategy changes caused by Korea fashion industry development process, the fashion marketing strategy changes of Japan, considered as the most similar one of Korea, was compared. At each period, p! roper cost efficiency strategies, product differentiation strategies, and market segment strategies has been selected and applied. The fashion industry foundation period namely practical usage clothing period of Korea follows 10 years after one of Japan. 90's highly sensitive fashion period namely fashion industry growth period follows 5 years after one of Japan. As entering to fashion industry maturity period with global competition, the time difference falls to less than 5 years. With hosting of 2002's World-Cup, Korea's global competitiveness has increased, and it appears to be possible of being fashion market leader in East Asia and Japan's rival on an equal footing.

According to globalization of world economy on distribution and sales, logistics and transportation parts are play important role. Especially, it important to know and study how to choose right transport route and which is the key factor of route choice model in multimodal transport system. Thus this study aims to consider 4 main factors: cost, delivery time, freight, and logistics service factors additionally dividing into 13 sub factors and object is forwarders between Mongolia and Korean freight transport. The survey is based on AHP through interview with company officials. The paper provides empirical insights about current status of Mongolian forwarders and difference of the important factors between transportation modes. Result shows that time factor is role factor to choose transport route and then cost factors. Additionally, this study shows 2 different route choose factors between air transport and shipping transport forwarders.

The strengthened aviation security measurements caused by increased terror threat all around the world have air passengers annoyed by uneasy treatment and some delayed process. The service level of air travel and competitiveness of airlines industry has been weakened also. The aviation security process is mainly conducted at an airport. The threat level of airport is not usually same airport to airport, and the quality of aviation security activity is neither same. However, ICAO requires every international airport to conduct similar process to ensure aviation security without considering situational difference of each airport. The paper has objectives to develop reasonable security measurements based on risk management concept. It studied the ways of achieving target level of security of an airport, considering the threat situation of the airport and its ability to conduct security procedures.

The English word-final /rl/ cluster poses a particular problem for Korean learners of English because it is the sequence of two sounds, /r/ and /l/, which are not contrastive in Korean. This study compared the similarity distances between English and Korean speakers' /rl/ productions using the dynamic time warping (DTW) algorithm. The words with /rl/ (pearl, world) and without /rl/ (bird, word) were recorded by four English speakers and four Korean speakers, and compared pairwise. The F2-F1 trajectories, the acoustic correlate of velarized /l/, and F3 trajectories, the acoustic correlate of /r/, were examined. Formant analysis showed that English speakers lowered F2-F1 values toward the end of a word, unlike Korean speakers, suggesting the absence of /l/ in Korean speakers. In contrast, there was no significant difference in F3 values. Mixed-effects regression analyses of the DTW distances revealed that Korean speakers produced /r/ similarly to English speakers but failed to produce the velarized /l/ in /rl/ clusters.

As the utility value of GPS in surveying field is on the increase after the conversion into the world geodetic system, it is attracting the interest of many people involved in the application of GPS. In this study an algorithm was established settling ambiguity through LAMBDA techniques and the baseline processing program was developed for L1/L2 carrier phase using visual c++ 6.0, which is an object-oriented language. And the developed program proved that it maintained a difference of less than 3mm over the short baseline of 1.5m or shorter when compared with other commercialized programs.

Northeast Asian economies have achieved high levels of growth due to a stable economic environments and economic policy reforms for free trade. As Northeast Asia has been risen as big bloc in the world and in the future in case free trade agreement could be concluded, trade volume could be increased dramatically. And it is evident that disputes will be increased in Northeast Asian economic bloc. Arbitration must be popular in resolving international commercial disputes in Northeast Asian bloc in order to increase the volume of intra-trade in the bloc. Through arbitration, the parties can have full autonomy and can resolve disputes independently, impartially and without delay. But in order for the parties to make use of arbitration in the bloc, they must be fully aware of the arbitration laws of Northeast Asian nations in view of the similarity and difference of the laws. Therefore, this paper deals with arbitral award in Northeast Asian Nations' arbitration laws in view of comparative law.

Alternate members of the Chinese Communist Central Committee are often overlooked regarding elite formation or even when assessing Chinese elites in general. This article focuses on the case of alternate members of the Central Committee from 1992 to 2007 in order to understand why some individuals will eventually be promoted and why some will never be. Through extensive quantitative testing, I argue that these non-promoted individuals differ from their counterparts in many ways, most of which can possibly be traced back to the type of formation they received early on. As such, the article concludes that Party School attendance and the age factor, through threshold analysis, are a significant factor helping us understand the difference between promoted and non-promoted houbu.

Geostationary Ocean Color Imager(GOCI), the World's first spaceborne ocean color observation satellite operated in geostationary orbit, was successfully launched on May 2010. The main missions of GOCI is the coastal environment monitoring of GOCI in order to meet the necessity of long-term climate change monitoring and research. The GOCI have higher spatial resolution than MODIS, $500m{\times}500m$, and 8 spectral ocean color channels. GOCI have a capability for observation on the coastal environment change, GOCI perform the observation with 8 times a day. In this paper, we presented the more improved results for observation on the coastal environment change than MODIS ocean color sensor and detected the spatial difference of CDOM for monitoring coastal environment change.
