Since 1970s, there are many tries to realize electronic bills of lading(e-B/L) in the world and great attention has been shown to the question of law, international trade customs and realizing strategy concerned that instrument. However that tries, include Bolero which is most famous company serving e-B/L, don't succeed yet. Meanwhile, Korean government amended commercial code in order to realize e-B/L on August 3, 2007. Also The Korea Paperless Trade Center set to develop the e-B/L system by spring of 2008. So far, however, no definitive answer has been given to the way of realization of e-B/L in Korea. Getting bigger the importance of analysis to the ways of realization of e-B/L in Korea, in this paper the author attempt to examine the requirements after briefly outlining and analysing the results and problems of the tries and suggest thereby policy and strategy about the realization classified three categories.

This study aims to examine similarities and differences of each e-B/L types as well as identify problems of e-B/L utilization and directions for improvement. Especially, it suggests strategies for the realization of e-B/L through reviewing and analyzing commercial types of e-B/L, which have been developed so far. Although e-B/L succeeded in realizing the function as a certificate of title and its distribution value, it has not been fully implemented due to operational problems. Subsequently, e-B/L was realized in the Bolero project as an attempt of system to make up for shortcomings in the failure of previous e-B/L types, but it has still a number of problems. To solve this problem and make use of e-B/L more efficiently, this study focuses on the specific ways to introduce e-B/L and suggest directions for the development of e-Nego system. Preparation of electronic documents is a prerequisite for the development of the e-Nego system, taking distribution of electronic documents into consideration. Next, compatibility of electronic documentation and paper-based documents should be realized, with the guarantee of authenticity of electronic documents.

The electronic bill of lading system replacing with traditional paper B/L has been evolved from SeaDocs and CMI to Bolero system. Therefore e-B/L is considered as an evolving concept rather than fixed one because it has been changed with development of information technology. Bolero system designed to replicate all functions of a paper B/L has some limitation to be utilized as an e-B/L in changing international business arena because it has a centralized model. Therefore it is considered to be important that the current e-B/L operating system needs to be diversified. This paper aims to provide three types of the operating model of global e-B/L to be applied with feasible solution coping with the current problems, which is expected to contribute to the utilization of electronic bill of lading.

Korea has accomplished the establishment of the National Single Window for Paperless Trade. Since 1991, it has developed Trade Automation Service System based on EDI technology. In 2003, Korean government and private sectors jointly began to set up National Paperless Trade Service( e-Trade Service) as one of the e-government projects. In 2008, they commenced the uTradeHub Service which was equipped with Internet based e-B/L and e-Nego service systems for the first time in the world To facilitate the service Korea amended its e-Trade facilitation Act and Law by 2007. At the end of 2011, Korea historically recorded its trade volume of 1 trillion US dollars and joined '$1 trillion trade club' as the 9the member country since the country had started international trade less than five decades ago. A rolling out of the e-B/L and e-Nego service will 'ally reduce the transaction costs of trading businesses and accelerate the activation e-trade services. The purposes of the study are to examine 'e-B/L Korea' service and its facilitation strategies as well as identify obstacles to utilize the 'e-B/L Korea' service. The paper reviewed and analyzed Korea's Paperless trade system and distinctive characteristics of the 'e-B/L Korea Service. Parts of the fOWld distinctive characteristics of the Korea's e-B/L service are as follows; It is well equiped with IT and legal system. It also has more that 30,000 potential users who are already uTradeHub service users. The paper indicated several weaknesses of the current system such as global KPI issues, circulation of the electronic documents not only in the domestic market but also among economies, development of the electronic Bill of Exchange. As resolution measures, the paper recommended the introduction of mutual recognition system of PKI among trade partner counties, setting up e-trade solution for small and medium companies, and special attention to raise users' awareness of the e-B/L service.

The influence of different doses of jasmonic acid on both biomass of adventitious roots and accumulation of secondary metabolite in bioreactor cultures of Eleutherococcus koreanum was studied. The maximum growth (2.9 g Dry Weight/L) of adventitious roots was observed in the absence of jasmonic acid. The biomass of adventitious roots decreased with the increase in jasmonic acid dosage. High level of jasmonic acid efficiently stimulated the production of both eleutheroside B and E. The highest eleutheroside B ($49.0{\mu}g/g\;DW$) was observed at 0.4 mg/L jasmonic acid. Jasmonic acid at 0.2 mg/L led to the maximum accumulation of eleutheroside E ($64.7{\mu}g/g\;DW$). Whereas eleutheroside $E_1$ was maximally $19.0{\mu}g/g\;DW$ accumulated in the absence of jasmonic acid, the total eleutheroside ($259.9{\mu}g/L$) was the highest when 0.01 mg/L jasmonic acid was treated. In this study, the level of eleutheroside B decreased whereas the maximum levels of eleutheroside E and eleutheroside $E_1$ were observed at 10th and 4th day after jasmonic acid treatment.

This study was carried out to investigate the dose-dependent effect of jasmonic acid on both the adventitious root growth and the accumulation of various eleutherosides in the Eleutherococcus senticosus bioreactor culture. The highest biomass production (4.6 g DW/L) was observed in the absence of jasmonic acid and the root growth was significantly decreased by increasing the jasmonic acid concentration. However, jasmonic acid stimulated the production of both eleutheroside B, E and $E_1$. The highest level of eleutheroside B and E ($476.3{\mu}g/g\;DW$ and $676.0{\mu}g/g\;DW$) was obtained by 0.5 mg/L jasmonic acid treatment, while eleutheroside $E_1$ was accumulated at the highest level by 0.01 mg/L jasmonic acid treatment. The highest content of total eleutheroside was $2468.6{\mu}g/L$ when 0.01 mg/L jasmonic acid was applied. In addition, when the adventitious roots were cultured with 0.01 mg/L jasmonic acid, the highest levels of eleutheroside B, E and $E_1$ were observed at the 6th, 8th and 4th day of culture, respectively.

It has been known that quercetin, a bioflavonoid widely distributed in fruits and vegetables as dietary-derived flavonoid and exert significant multiple biological effects such as antioxidant and anti-inflammatory, anti-tumor effects. In addition, it has been shown to have a chemoprotective role in cancer, though complex effects on signal transduction involved in cell proliferation and angiogenesis. The present study investigated whether quercetin can enhance antioxidant enzyme activity (glutathione peroxidase: GPx, superoxide dismutase: SOD, catalase: CAT) and regulate the reactive oxygen species (ROS) generation in the presence of vitamin E, L-ascorbic acid, reduced glutathione (GSH) on B16F10 murine melanoma cells. After 48h treatment of cells with quercetin in the presence of vitamin E, L-ascorbic acid, GSH, we measured the cytotoxicities by MTT assay. The cells exhibited a dose-dependent inhibition in their proliferation in the presence of vitamin E, L-ascorbic acid, GSH respectively. We also investigated the effects of antioxidant enzyme activity and ROS generation. The antioxidant enzyme activity of quercetin in the presence of vitamin E was stronger than GSH, L-ascorbic acid, the same treatments decreased ROS generation in B16F10 murine melanoma cells. Taken together, these result demonstrate that the antioxidant effect of quercetin can enhanced in the presence of vitamin E and it might plays an important role in anti-oxidative effects.

This study tried to analyzed the relationship outcome and commitment in order to suggest to a outcome for commitment decision-making of e-trade. 6 hypothesis were constructed for analysis based on previous literature review. The subject of this study is to analyse on electronic trade practice outcome on the international trade practice commitment. This paper investigates the outcome determinants of e-trade commitment. There are 250 sended samples and 188 returns, 168 of them are analyzed on commitment for a electronic trade outcome. The first, multiple regression result shows that the international trade practice outcome are positively affected by the "Overseas market research commitment", "e-L/C Practice commitment", "Clearance Practice commitment", "e-B/L or global logistic commitment", "Payment or e-Nego commitment". However, The "Commerce practice commitment" factors does not affect in the electronic trade practice outcome.

The influence of different growth regulators on biomass of adventitious roots and secondary metabolites accumulation in bioreactor cultures of Eleutherococcus koreanum was studied. The maximum growth of adventitious roots was observed in the presence of $2.0\;\cal{mg/L}$ IBA (6.7 g DW/L). However the productivity of eleutheroside E was not significantly different among IBA levels. High level of thidiazuron (TDZ) efficiently increased both root growth and secondary metabolites production. Especially when $0.1\;\cal{mg/L}$ TDZ was combined with $3.0\;\cal{mg/L}$ IBA, the highest eleutheroside E accumulation ($3,327{\mu}g/g $DW) was observed. When the same TDZ level was treated in combination with $5.0\;\cal{mg/L}$ IBA, both chlorogrnic acid and eleutheroside B were accumulated to maximum level. In contrast, zeatin remarkably suppressed the accumulation of both eleutheroside B and chlorogenic acid.
