Korea-China FTA and Korea-U.S. FTA are the most significant FTA in volume and economic effect for Korea's perspective. Developed countries have dealt with environmental issues one of the main issues in FTA negotiation, while developing countries have been reluctant to it. Both Korea-China FTA and Korea-U.S. FTA have separate environment chapter respectively. A separate environment chapter was firstly introduced in Korea-U.S. for Korea's perspective. Both environment chapters provide high level of environment protection, recognition of multilateral environmental agreements, enforcement of environmental laws, and environmental cooperation. Both environment chapters require that each party make effort to improve environmental laws and measures. Korea-China FTA provides establishment a "Committee on Environment and Trade", and Korea-U.S. FTA provides establishment a "Environment Council" to oversee the implementation of environment clauses. Korea-China FTA and Korea-U.S. FTA have very similar provisions on environment and trade, and are expected to contribute to enhancing environment protection. However, a lot of provisions are somewhat declaratory rather than mandatory. Therefore, further environmental cooperation is encouraged to achieve the goals and objectives of the environment clauses and FTA.

The Republic of Korea (South) and the Peaples Republic of Korea (North) had agreed to exploit the North Korean rich natural resources starting from the year of 2006. Through this mutual agreement DPRK shall quarantee ROK's investment in the North Korean Mines and supply mineral products for the compasation of the financial investment supported by ROK. In the area of northern part of Korea, many kind of natural resources such as Magnesite, Iron, Gold & Silver, Copper, Lead & Zinc, and Coal are plentifully deposited. In the area of southern part of Korea, however, most kind of natural resources have been exhausted and so presently major minerals such as Gold & Silver, Copper, Lead & Zinc and Coal are being imported and relying on foreign countries in whole quantity of the requirement. On the other hand Northern Part of Korea is making very slow progress in mining and exploitation owing to the lack of investment even though there are rich deposits of natural resources. And in Southern Part of Korea, they have most advanced production facilities and technologies in the world in the fields of Mineral Floatation, Steel Manufacturing, Nonferrous Metal Smelting & Refining and those plants fabrications. A combination of Southern Technologies together with Financial Support and Northern rich natural resources & Labour Power will be a most hopeful, desirable and mutually required 'South-North economic Cooperation' as the mining industries are labour intensive.

A composite pile consisted of a concrete lower part with a steel tubular pile at upper part was installed by pre-drilling method. Seven pairs of strain gauges and inclinometer were attached on the pile in order to measure stresses and displacement along the pile during the lateral loading test. The results of instrumentation were analyzed using various theoretical approaches. The back analysis showed that the measured stresses were smaller than those of the calculated. The maximum stress is measured at the steel upper part and decreased rapidly with depth of the pile. The calculated lateral displacement along the pile provide very good agreement with the measured values if the coefficient of subgrade reaction is selected properly. The design concept of a composite pile is verified by the measured stresses and displacement which is within the tolerable limits of the pile.

The dynamic analysis of delaminated composite structures is carried out based on the higher order plate theory. In the finite element (FE) formulation, the seven degrees of freedom per each node are used with transformations in order to fit the displacement continuity conditions at the delamination region. The boundaries of the instability regions are determined using the method proposed by Bolotin. The numerical results obtained for skew plates are in good agreement with those reported by other investigators. The new results for delaminated skew plate structures in this study mainly show the effect of the interactions between the geometries and other various parameters.

This study presents the preform injection molding and the blow molding of the injection stretch-blow molding process for PET bottles. The numerical analysis of the injection molding and the blow molding of a preform is considered in this paper using CAE with a view to minimize the warpage and the thickness. In order to determine the design parameters and processing conditions in injection/blow molding, it is very important to establish the numerical model with physical phenomenon. In this study, a three dimensional model has been introduced for the purpose and flow simulations of filling, post-filling and cooling process are carried out. The simulations resulted in the warpage in good agreement with the measurements. Also, from the result of numerical analysis, we appropriately predicted the warpage, deformation and thickness distribution along the product walls.

In this paper, we investigate the static response. natural frequencies and buckling loads of functionally graded material (FGM) plates, using a Navier method. The eigenvalues of the FGM plates and shells are calculated by varying the volume fraction of the ceramic and metallic constituents using a sigmoid function, but their Poisson's ratios of the FGM plates and shells are assumed to be constant. The expressions of the membrane. bending and shear stiffness of FGM plates art more complicated combination of material properties than a homogeneous element. In order to validate the present solutions, the reference solutions of rectangular plates based on the classical theory are used. The various examples of composite and FGM structures are presented. The present results are in good agreement with the reference solutions.

In this study, we aim to build a consensus that the Korea-Mongolian economic cooperation and trade growth will bring economic benefits to both countries and, in addition, the FTA between the two countries will bring economic benefits to the overall economy through the economic status and mutual trade status of Korea and Mongolia. Currently, countries around the world are accelerating their market battle with fierce competition, pushing for the opening of their markets through free trade agreements of multilateralism and regionalism centered on the WTO as a rapid change in the global economic environment. Amid such an international economic environment, Korea is developing diverse economic cooperation and FTA strategies, and under the principle that it is based on comprehensive and national consensus, it will sign simultaneous FTAs with major countries, but will diversify its trade partners' efforts to increase trade volume through market advantage, secure energy resources, and so on to secure more resources in overseas markets.

Recently, an understanding of new sources of liquid hydrocarbons such as bio-ethanol is economically very important. Successful design of distillation columns in a separation process depend on the availability of accurate vapor-liquid equilibrium data. For the binary system of Ethanol/3-methyl-l-butanol mixture, isothermal Vapor-liquid equilibrium data were measured at temperature of 50, 55, 60, 65, 70, 75 and $80^{\circ}C$. An empirical relation to predict Vapor-liquid equilibrium data was obtained from the above measured data. The predicted values are compared with the measured ones to be in a good agreement within accuracy of ${\pm}0.0005$, ${\pm}0.0022$.

In this paper, the Low Pass Filter (LPF) using the equivalent circuit of T-junction microstrip line is proposed. And we derived the formulas for lumped-elements of the equivalent circuit of T-junction microstrip line to solve the frequency shift characteristic. T-junction microstrip line is de-embedded by Electromagnetic simulation tool and exact lumped element value of T-junction microstrip line is calculated by the equation of Z-parameter. We can get excellent agreement between lumped-element LPF frequency response and transmission line LPF frequency response.
