Due to the global warming and economic crisis, automakers are currently focusing on the development of high fuel-efficiency vehicles. To accord with these requirements, steelmakers have been trying to develop advanced high-strength steels with improved automotive-related properties. In addition, galvanizing technologies have been developed to improve coating properties for AHSS (Advanced High Strength Steel) such as pre-oxidation and pre-coating, as well as roll dent prevention. In this paper, newly developed products and technologies for automotive galvanized steel sheet are reviewed.

The situation in Korean peninsula, globally and regionally, which followed the global huge uncertainty, changed a lot. Because of the political crisis, ROK falls into a chaos. And DPRK goes into a policy changing period by the internal issues, international sanctions and assassination accident in Malaysia, which is confirmed to be DPRK's Supreme leader, Kim Jong Un's half brother. Under this changing circumstances, the perspectives of regarding China and the Korean peninsula, must be undated accordingly. Only by understanding the Sino-US relations, the DPRK nuclear issue and the regional dilemmas can we formulate reasonable policies to contribute to the peace and stability of the Korean Peninsula.

In the recent 20 years, the capital flows between Korea and European Union have increased and diversified. In particular, the business cycles of two economies have shown similar patterns since the Global Financial Crisis. This study examines both trends and investigates the roles of finance and trade on business cycle co-movements between two economies. The empirical results show that the business cycles can diverge due to either the common shocks or the country-specific shocks. Furthermore, financial integration increases the business cycle co-movements driven by both the country-specific shocks and the common shocks between two economies.

The burden of housing heating costs has increased as energy prices such as global oil prices (28.1%), LNG (38%) and minerals (100%) have soared due to the Ukraine crisis. Accordingly, an electrically conductive cement composites had developed using waste carbon materials such as waste cathode materials, waste CNTs, and waste carbon fibers, and the heat generation performance was evaluated.

Under the global economic system, production activities has formed an international division of labor, which has greatly affected industries in individual countries by global issues such as the U.S-China trade war and neo-protectionism. In particular the risk and change of disconnection of semiconductor value chain caused by COVID-19 are evaluated as offering the crisis and opportunity at the same time to all countries participating in the global electronics industry value chain. Therefore, this study was conducted with the OECD Trade in Value Added(TiVA) based on the time when a detailed analysis of the global chain of the electronic industry is needed. As a result of the analysis, it was confirmed that the global value chain of the electronics industry is gradually expanding and strengthening, and that various countries are emerging as major actors in the global value chain. It was found that the U.S. and Japan are in charge of relatively high value-added activities, while Korea, Taiwan and China are in charge of low value-added activities, although they are large scale.

Emerging global economic growth and increasing demand for energy supply and demand imbalance and the excessive use of fossil fuels existing the rapidly increasing greenhouse gas emissions and resource depletion of global energy crisis is deepening. Accordingly, improvement of living conditions around and through the natural ecological preservation and the need for a comfortable life for the meeting the importance of energy management and consumption are emerging. Many in the field of architecture for energy-saving measures and conducts research and analysis from the early stages to verify the energy performance of BIM (Building Information Model) technology development and commercialization through the building's energy performance to an objective technology forecasts Analysis of the existing building energy performance in waste management also possible that "BIM-based green building process, the possibility of" suggested. In this study, BIM through the analysis of information using the structures for the management of waste, energy and physical data collected by Mapping it can effectively plan resources for recycling were analyzed.

Amid a general rise in protectionism and a trade war between the world's two largest economies, this paper analyzes changes in gains from trade for the world over a decade marked by rapid global economic integration preceding the global financial crisis of 2007-08. It employs state-of-the-art quantitative trade models based on the gravity equation to estimate autarky gains from trade, as well as a recently introduced ANOVA-type structural estimation of the gravity equation to obtain trade costs free of residual trade cost bias. Between 1995 and 2006, the cost of moving to autarky increased by about 45% on average. A decomposition exercise suggests most of the increase in autarky gains from trade on average was due to increases in import shares in total spending, with a limited role for reallocations of spending across sectors with varied trade elasticities. Changes in trade costs between 1995 and 2006 are found to have increased autarky gains from trade, as measured in 2006, by up to 100%.

The purpose of this study is to analyze the technical and cost efficiency of Air Transport Industry on Global strategic alliances. In particular, this study develops Stochastic Frontier Approach for accurate judgement. Based on 20 major international airline corporations related with strategic alliances during the period 1995-2001, we find that alliances make a significant contribution to efficiency. On the other hand, it is found that the level of contribution to efficiency is different according to alliances. These results also changed greatly between pre- and post- Asian financial crisis period.

Plant biotechnology including plant tissue culture is the most important science to rescue human beings from the crisis of biosphere of the earth which they will face in the 21st century. Global area other than Asia of trangenic crops increased more than 16 times from 1996 to 1998. In Asian countries, micropropagation using tissue culture techniques has been well developed and has contributed to agricultural production. Although researches on levels of laboratory and test field trial of transgenic crops have been performed actively in some Asian countries, areas of growing transgenic crops are still small in Asia countries except in China. In this paper, the status of plant biotechnology in global and Asian countries are reviewed and the future prospect of plant biotechnology in Asia and roles of Korean and Japanese plant scientists in it are discussed.

In recent years, the usage of fossil fuels has caused problems of climate change and global warming. Because the combustion of fossil fuels is related to the production of greenhouse gases ($CO_2$, $CH_4$, etc.), new technology in the field of combustion is needed in order to handle the crisis of climate change and the global warming. As one of the efforts to reduce the emission of greenhouse gases, the concept of regenerative oxy-fuel combustion for energy efficiency and carbon capture was suggested, In the current study, the development of an industrial regenerative oxy-fuel combustion furnace was introduced, which has been being performed at Korea Institute of Energy Research (KIER).
