The global seasonal forecasting system version 6 (GloSea6) operated by the Korea Meteorological Administration for 1- and 3-month prediction products does not include complex atmospheric chemistry-aerosol physical processes (UKCA). In this study, low-resolution GloSea6 and GloSea6 coupled with UKCA (GloSea6-UKCA) were installed in a CentOS-based Linux cluster system, and preliminary prediction results for the spring of 2000 were examined. Low-resolution versions of GloSea6 and GloSea6-UKCA are highly needed to examine the effects of atmospheric chemistry-aerosol owing to the huge computational demand of the current high resolution GloSea6. The spatial distributions of the surface temperature and daily precipitation for April 2000 (obtained from the two model runs for the next 75 days, starting from March 1, 2000, 00Z) were compared with the ERA5 reanalysis data. The GloSea6-UKCA results were more similar to the ERA5 reanalysis data than the GloSea6 results. The surface air temperature and daily precipitation prediction results of GloSea6-UKCA for spring, particularly over East Asia, were improved by the inclusion of UKCA. Furthermore, compared with GloSea6, GloSea6-UKCA simulated improved temporal variations in the temperature and precipitation intensity during the model integration period that were more similar to the reanalysis data. This indicates that the coupling of atmospheric chemistry-aerosol processes in GloSea6 is crucial for improving the spring predictions over East Asia.

In the era of globalization, small and medium sized businesses (SMBs) are striving to attain competitive advantage in the rapidly changing and diversified markets. It is necessary for SMBs to enhance their global compentency in order to successfully enter overseas markets. In an attempt to shed light on how closely an SMB's global competency is related to how efficiently their employees can perform their tasks in the overseas market, this study examined the nature of English use in oral communication by twelve Korean men working in Dubai. Questionnaires and recordings were used to collect the data. The results show that English competency plays a crucial role in work efficiency in the overseas business context. Also, superior oral skills are considered the most important in doing business as it is the most frequently required form of communication. Participants of the study showed a tendency to make up for their lack of communicative competency by using various strategies. They tried to avoid communication breakdown by all means in order to get the task done.

The Modem Geodesy monitors physical and geometrical shape and motion of the Earth and, more importantly, its temporal variations with unprecedented precision. It provides accurate and stable reference frames for Earth observations in the Space era. Furthermore, with an aid of interdisciplinary approaches, it also traces the causes of the variations in shape and motion of the Earth and eventually contributes to a better understanding of the Earth system. The International Association of Geodesy (IAG) has established the Global Geodetic Observing System (GGOS) to integrate the multitude of geodetic tools and tried to contribute to the management of global environmental changes as a partner of the Global Earth Observation System of Systems (GEOSS). Here we introduce the contribution of geodesy to the various fields of Earth Science by focusing on GGOS and encourage interdisciplinary researches.

With deepening globalization, various problems happening all over the world have not been limited to a country any more, but have had an influence over neighboring countries and international community. To deal with these problems international cooperation is getting important. Thus, over the existing individual- and state-centered thought, the alternative education is required to teach how to make a sustainable society and what to do for living together. In particular, current students are asked to be equipped with proper knowledge and attitude since they are to live as a global citizen beyond the Korean citizen in globalized era. This study analyzes the status of development education in other countries and in Korea, and it also suggests the use of terminology, approach to teaching, educational contents, and last but not least how to link the regular school curriculum in elementary, middle, high school.

In order to understand the Holocene sea level changes in the eastern Yellow Sea, the west coast of Korea, and to compare the rates of sea level rise in each period of time, the geological proxy records for pre-instrumental era and measurement data for the present day were combined and analysed. The sea level in the Yellow Sea rose fast with a rate of about 10 mm/yr during the early Holocene, and decelerated down to 1 mm/yr since the mid to late Holocene. The rising rates of sea level in the 20th century were slightly higher than those in the late Holocene. The present-day rates of sea level rise, known as the 'rapid' rise, are in fact much lower or similar, compared to the early to mid Holocene sea levels in the study area. Recent tide-gauge data show that sea level rise in the eastern Yellow Sea has been accelerating toward the 21st century. These rising trends coincide well with global rising patterns in sea level. Additionally, the present-day rising trends of sea level in this study are correlated with increased rates of carbon dioxide concentrations and sea surface temperatures, further indicating a signal to global warming associated with the human effect. Thus, the sea level changes induced by current global warming observed in the eastern Yellow Sea and world's oceans can be considered as 'Anthropocene' sea level changes. The changes in sea level are based on instrumental measurements such as tide-gauges and satellite altimetry, meaning the instrumental era. The Holocene changes in sea level can thus be reconstructed from geological proxy records, whereas the Anthropocene sea-level changes can be solely based on instrumental measurements.

This paper explores the formation of global responsibility discourses in the elite US media used in promoting NATO's military interventions in the post-Cold War era. The case study of global responsibility discourses surrounding the Bosnian War (1992-1995) and the Kosovo Conflict (1998-1999) offers an account of the roles of the elite US media in foreign policy. The construction and articulation of global responsibility discourses in the elite US media were closely related to the US government's policy and were formed within the framework of US national interest and domestic responsibility. The cases of military intervention in the post-Cold War period imply that there were more fundamental structure and patterns by which the elite US media approached the 'humanitarian crises': 'benevolent domination' and the subsequent construction of a 'melodramatic national identity' in the war narratives. Presuming that the elite US media's discourse is a primary site for the public for experiencing and understanding distant suffering, this paper concludes that global responsibility discourses within the media may have dangerous ramifications for global democracy because the discourse of responsibility can potentially absorb the creative, progressive energies created by the public's awareness of responsibility on a global scale in order to reinforce the relations of domination.

The world is now meeting the era of e-commerce by development of information technology and the fast increase of use of internet. So, Korean government prepared "the colligation plan for electronic commerce activating" and WTO decides to prolong no custom on e-commerce till November 2001 when the fourth WTO Ministerial Conference holds a meeting. OECD discussed the construction of intellectual property rights of the global dimension at the Global Forum on January 2001 and reached to research the social influence of B-to-B e-commerce and to pursue the acceleration of e-commerce. UNCITRAL(United Nations Commission on International Trade Law) enacted UNCITRAL Model Law on Electronic Commerce in order to activate e-commerce, and Bolero.net serves electronic Bill of Lading to facilitate cyber trading. The purpose of this paper is to present the direction of confrontation to the these internal and external changes of business environment to Korean enterprises. Off-line enterprises should move fast to e-commerce on the condition that the existing trading at the original markets runs parallel with e-commerce. n needed, off-line enterprises should consider M&A with existing on-line firms. Also, off-line firms make use of Bolero system so that they can carry through paperless trade which means the achievement of efficiency in trading, On-line enterprises should advertise in the form of banner by combination of push and pull styles. B-to-B e-commerce firms should not depend on only the commissions, but they should create characteristic earnings by their peculiar services.

Revolution of Shale gas literally brings about great changes in many spheres. In the past most academic research had been focused on the influence and innovative change in term of economic perspective. But nowadays we should more concern about the security approach and perspective as its status of the future's core energy resources. Revolution of Shale gas has an great influence on the reshaping of global and regional alliance order. There are many international political implications as follows. Contribution of energy hegemony with leading U.S.; Acting as strategic leverage on the reshaping international order; Deepening competition among major states on the construction of energy security and so on. We'd better make a good solution and systematic policies which are preparing for the Shale gas's revolution period including on the understanding about the change on the global energy structure and making a national policy agenda of energy security issues and so on. The thesis like 'to get the energy resources is to get the hegemonic power in the world' will persist. The same holds good of Shale gas case. To meet the revolution of shale gas era, we have important tasks as like making an opportunity to develope not only regional but also international prosperity.

These days, Korean government has been expanding Free Trade Agreement (FTA) with major countries. Expansion of FTA, which means opening up the markets, can be the opportunity to develop for those enterprises with global competency; however, it surely brings disadvantages to such small and medium enterprises which function as an outsourcing and a subcontracted to large enterprises. For Korean economy to overcome the national income of US$20,000 and to jump up to the level of advanced countries, it is imperative to perceive a limit to the large enterprises only. Not only the leading efforts of small and medium enterprises to double the exports, but also realizing the policy reform for the consistent and intimate policy between the government and companies have to be proceeded. Therefore, primarily in this study, first, it includes the overview of the change in trade-environment in an era of FTA, governmental system and policy to support export for the small and medium enterprises; secondly, examination of the export capacity and some problematic factors in export for small and medium enterprises. Ultimately, it is suggested both reinforcement for global competency of the small and medium enterprises and an alternative policy for the support system in the time expecting export expansion.
