  • The long-term trends of global solar irradiance, air temperature, specific humidity and cloudiness measured at King Sejong station, Antarctica, during the period of 1988-2004, have been investigated. A statistically insignificant decrease, -0.21 $Wm^{-2}yr^{-1}$ (-0.26 %$yr^{-1}$, P<0.5) in global solar irradiance was found in an analysis from the time series of the monthly mean values, except for the increasing trends only in two months of January and June. The trends in irradiance are directly and inversely associated with the cloudiness trends in annual and monthly means. The trends in surface air temperature show a slight warming, $0.03^{\circ}Cyr^{-1}$ (1.88 %$yr^{-1}$, P<0.5) on the annual average, with cooling trend in the summer months and the warming in the winter. The exact relationship, if any, between the irradiance and temperature trends is not known. No significant tendency was found in specific humidity for the same periods. Recent (1996-2004) erythermal ultraviolet irradiance shows decreasing trend in annual mean, -0.15 $mWm^{-2}yr^{-1}$ (-1.18 %$yr^{-1}$, P<0.1) which is about five times the trends of global solar irradiance. The ratio of erythermal ultraviolet to global solar irradiance shows remarkable seasonal variations with annual mean value of 0.01 % and a peak in October and November, showing the increase of ultraviolet irradiance resulting from the Antarctic ozone hole. The sensitivity of global solar irradiance to the change in cloudiness is roughly $13%oktas^{-1}$ which is about twice of the value at the South Pole due to the difference in the average surface reflectance between the two stations. Much more sensitive values of $59%oktas^{-1}$ was found for erythermal UV irradiance than for the global solar irradiance.

  • It is said that global business education in Korea must be a kind of good investment on the future of Korea, because Korea's degree of dependence upon global trade is very high. But, despite great significance of trade in economic aspect, education system on global business in Korea still remains in old paradigm focused mainly on trade in goods. The purpose of this paper is to analyse key environment of trade in Korea relating to global business education system, and to suggest some trade-friendly measures to improve the global economic environment being worse. Methodology used in this study depends on descriptive analysis by literature study. As all the paradigm of global business has shifted from 20C's trade environment to that of 21C's and still more borderless trend has progressed, it is high time Korea to design the new education system of global business to conform with the trade mode of Korea, and to execute the mode of strategic trade which is new conception of trade strategy derived from Web 2.0 trend. Major findings of this study can be summarized as follows : It is suggested that Korea should convert basic composition of trade strategy to strategic trade irrespective of company size, nationality, public or private sector, etc., and launch new instructional model considering the trade 2.0 concepts. Also, Korea's trade policies which have been based on 'trade in goods' should be changed to the frame of strategic trade so that can include various trade process such as trade in services, trade in technology, cultural contents, global investment(TRIMs), TRIPS, etc.

  • Korea's domestic construction market and overseas construction order environment are experiencing a decreasing trend, and this trend is expected to continue. Therefore, domestic construction companies are seeking to enter the global construction market. This study analyzes the global construction market and the global competitiveness for global construction companies and provides the results. To this end, this study has developed a model to evaluate the global construction competitiveness level and to evaluated global construction competitiveness in 2016. The evaluation of global construction competitiveness was analyzed based on the competitiveness of construction infrastructure by country, and the evaluation results of competitiveness of construction companies. These assessments were based on 20 detailed international statistics (ENR, Global Insight, Compass, etc.). The evaluation results are as follows. First, in regard to the comprehensive global construction competitiveness by country, America ranked first among 20 countries, followed by China. European countries like Spain, Germany and the Netherlands ranked third to fifth, respectively. Korea ranked sixth, one rank higher than that of the previous year. America and European countries remain strong. Second, in regard to the comprehensive building infrastructure competitiveness by country, America ranked first followed by Germany. Korea ranked twelfth, which is the same rank as that of the previous year. When it comes to stability in the construction market, China ranked first and Korea eighth. For construction systems, Sweden ranked first and Korea thirteenth, and for infrastructure, Japan ranked first and Korea tenth. Third, according to the construction company's capability evaluation by country, America ranked first followed by China. Korea ranked fourth, two ranks higher than that of the previous year because of its building competitiveness (fifth → fourth) and design competitiveness (eleventh → eighth) which has improved. When it comes to building competitiveness, China ranked first and Korea fourth. For design competitiveness, America ranked first and Korea eighth, and for price competitiveness, India ranked first and Korea seventh. However, Korea is still in the middle of the pack rank among the 20 countries considered when it comes to design competitiveness. It is ranked eleventh for design productivity and thirteenth for foreign sales against the total sales (internationalization). Thus, Korea needs to improve technical power and tap into new markets for improved competitiveness, including increased productivity. To do so, more R&D investment is required.

  • The purpose of this article is to explore recent developments in piracy attacks at the global level. This article provides an overview of global trend of recent piracy attacks and presents global counter-piracy efforts at the international and governmental as well as industry level. The issue of piracy has been a grave concern of the globe, becoming the biggest threat to the safety and security navigation and seaborne trade. Overall, piracy attacks in recent years have greatly diminished owing to multi-faceted counter-piracy efforts. However, Southeast Asia and West Africa have reemerged as an hotspot of piracy. A worrisome trend in these regions is that many of piracy attacks are committed by militant groups for financing their activities. As a result, the level of violence and the sophistication of attacks have escalated. The problem of contemporary piracy is beyond a particular region or coastal state, but a common concern of the international community. In order to address the global piracy problem, international cooperation should be further strengthened at the global level as well as the regional level. As a way of counter-piracy measures in Southeast Asian waters, the creation of a joint regional coast guard to patrol the highly piracy concentration areas needs to be considered.

  • The world is suffered from severe environmental problems such as climate change and global warming due to radical industrialization after the Industrial Revolution. With advancement of science and information technologies, national borders have become meaningless. In this global trend, movable exhibition shall be supposed to pursue "Local in Global." Thus, movable exhibition should get involved in an effort to find a cultural identity in the globalization and to better our position among the various cultures. As an alternative, movable exhibition can be established by combining biomimicry, which is biomimicry of life by imitating biological system, with Flexibility of movable space. By providing a hint to environmental problems and cultural uncertainty, this alternative will generate an advanced exhibition trend that is more environmental-friendly and more efficient. As a cumulative concept created by the nature for 3.8 billion years, biomimicry has evolved a lot more than the modern science. By catching this point, "A study on flexibility of movable exhibition through biomimicry notion" is providing a revolutionary paradigm stepping beyond the current exhibition trend, which pursues coexistence of human beings and the nature and, at the same time, introduces our culture.
