Current status of soybean transformation method in Korera was reviewed with recent publications. Most frequently used method for genetic transformation was Agrobacterium-mediated transformation on cotyledonary node which is most popular method used in foreign country. In addition to this, various methods such as sonicationmediated transformation, in planta transformation, and transformation on meristem tissue of germinating seed, have been tried in Korea, even though their efficiencies on repeatability and stability were relatively low. Based on the promising results developed recently by reviewer, several important considerations for successful soybean transformations were suggested. They are 1) proper genotype screening, 2) targeting transformation on exact point, 3) multiple shoot formation, 4) efficient selection pressure, 5) successful shoot elongation, 6) efficient root formation. These are the basic requirements for stable and highly efficient soybean transformation of Korean soybean.

Downcoiler is one of the major facilities in hot strip mill operation. The key to good coiling is having good equipment, modem control systems, excellent maintenance and an understanding of coiling process. Therefore, this study aims to develop a program that is useful for calculating machine design parameters and simulating coiling process. In this study, the pinching and coiling mechanism of the downcoiler was thoroughly studied and some of operational factors and their effects on the coiling process were investigated. The software was developed to estimate engineering parameters for coiler component design and to determine optimal setting values for successful coiling operation. In order to check the accuracy and usefulness of the developed software, the simulation of the downcoiler in $\#2$ Hot Strip Mill in Pohang Works was performed. The simulation results suggested that the set-up value for unit tension could be lowered. Test coiling operation by using the lowered set-up value for unit tension resulted in much more successful coiling in the aspect of strip quality and power consumption.

It is important to investigate into the critical success factors(CSFs) of the CIO system in order to formulate a successful introduction strategy of the system. In an effort to provide the strategy, this research attempts to identify the CSFs of the system in the organizations of the private and public sectors in Korea. A result from the analysis of data collected shows that most organizations in Korea have already adopted, or are planning to adopt, the CIO system, implying that the value of the system is well recognized. Another result suggests that the success of the CIO system necessitate the CIO's abilities to recommend adequate IT and to apply appropriate IT solutions for the organization.

Many organizations are operating knowledge management(KM) for their competitive advantage in dynamically changeable markets. To support KM successfully, they are considerably investing in knowledge management systems(KMS) development. By using KMS, organizations can lead to the improvement of their employees' knowledge level and the removal of inefficient tasks, consequently resulting in their competitive edge. On the basis of the power process perspective, this study investigates the CEO leadership and its organization's performance for successful development of KMS.

The IMD(International Institute for Management Development) report said that national competitiveness of Korea is declined in this year. The main reason for Korea's decline is a largely related to the weakness of corporate competitiveness. The new product development is a necessary ingredient for improving the national competitiveness. The analysis of changing of technologies and customer's needs is needed for successful new product development. In this paper, We found out successful factors of the project by use of DFSS(Design for Six Sigma) and proved them by case study of K-company. Result from this paper is applied to the new product development planning step for K-company and it made a great success rate. It is expected that the result is applied to the same kind industries.

In describing the plastic deformation behaviour of ultrafine-grained materials, a phase mixture model in which a polycrystalline material is regarded as a mixture of a crystalline phase and a grain boundary phase has been successful. The deformation mechanism for the grain boundary phase, which is necessary for applying the phase mixture model to polycrystalline materials, is modelled as a diffusional flow of matter along the grain boundary. A constitutive equation for the boundary diffusion creep of the boundary phase was proposed, in which the strain rate is proportional to (stress/grain siz $e^{2}$). The upper limit of the stress of the boundary phase was set to equal to the strength to the amorphous phase. The proposed model can explain the strain rate and grain size dependence of the strength of the grain boundary phase. Successful applications of the model compared with published experimental data are described.

We report the successful treatment of feline acute bullous keratopathy (FABK) and corneal perforation with a conjunctival hood graft. Two cats with FABK and corneal perforation had severe corneal edema with large central bullae. Their corneas were thinned and perforated. Conjunctival hood grafts were performed. All corneas recovered after 3-4 weeks. The grafts were then removed from the cornea using superficial keratectomy and no ocular irritation was observed. One month later, the corneas had recovered, although there was very mild fibrosis. The cats had normal vision without any corneal problems at this time. Conjunctival hood graft was thus useful for the treatment of severe FABK and allowed the cats to maintain vision.

Within the group of congenital cardiac anomalies manifesting dextrocardia and double-outlet right ventricle, ventricular non-inversion [S.D.L] is extremely rare. Recently, a 5 year-old boy underwent a successful surgical correction of dextrocardia associated with double-outlet right ventricle, ventricular non-inversion [S.D], ventricular septal defect, pulmonary stenosis, and patent foramen ovale. The operation consisted of construction of an internal baffle connecting the left ventricle to the aorta through the large ventricular septal defect [subaortic]. The pulmonary stenosis was managed by infundibulectomy and patch enlargement of the right ventricular wall. The patient`s postoperative recovery has been uneventful, and 2 months after the operation, he is doing well.

Marketable permit system (MPS) is a economic incentive instrument that allows polluters to achieve static and dynamic efficiency, However, Korea's atmospheric regulations are primarily based upon command and control (CAC) system and partly upon economic incentive instruments, which fail to realize its relative effectiveness, Accordingly, an introduction of MPS has been recommended with the cost effectiveness analysis in numerous studies, The literature, however, did not consider the relationship between MPS and the existing regulations, which is a key factor for the successful introduction of MPS, This paper provides a set of principles to judge how the existing regulations are reconciled with the introduction of MPS, In addition, authors execute an empirical study to show MPS's cost effectiveness when regulators apply MPS in Ulsan area for the abatement of sulfur dioxide, The results suggest that the regulations such as fuel regulation should be excluded when implementing MPS, and a flexibility in legal and regulatory system is to be required in order to secure a successful implementation of MPS.

Because of their unique properties, supercritical fluids have been known as one of the most promising materials for the future technology. Supercritical fluid technologies have been widely applied to various operations such as extraction, impregnation, nano-particle generation, oxidation, reaction etc. Industrial applications, especially their successful usage of supercritical fluid, have been reviewed. A special case for the first successful industrial application of supercritical $CO_2$ extraction in Korea was reviewed. Its unique characteristics of enriched antioxidant, $'\grmma-tocopherol'$ enabled this industrial application in Korea in spite of its low market price. Also its size and operation conditions were known as world records.
