Korean apparel industry is facing critical moment due to shortage of labor, wage increases and intensive competition among domestic manufactures. In addition, international production has been shifting to China and the other low-wage countries from established locations such as Korea, Hong Kong and Taiwan. Global sourcing has been received considerable attention since firms can enhance their competitive advantage as well as comparative advantage by coordinating their sourcing activities global]y. This studs regarded global sourcing as one of the strategic tools to achieve competitive advantage of Korean apparel firms, and explored the current status by literature reviews and series of in-depth interviews with managers of korean apparel firms. The findings of this study were as follows: 1) Due to geographical advantage, China was the most favored nation for outsourcing for domestic markers. However, exporting firms preferred Latin America (including Mexico) to take advantage of duties, quotas and geographical proximity to the US market. 2) In selecting the global sourcing country, productivity, technical ability, local government regulation, and culture were considered important. 3) Most Korean apparel firms sources production globally, and followed by raw materials and trims. 4) Cost and quality were the most important factors in deciding subcontractors, and experience, productivity, equipment and finances were the next concerns. Academic implications and future directions were suggested based on findings.

A simple, accurate and efficient mesh generation technique, the cut-cell method, is able to represent an arbitrarily complex geometry. Both structured and unstructured grid meshes are used in this method. First, the numerical domain is constructed with regular Cartesian grids as a background grid and then the solid boundaries or bodies are cut out of the background Cartesian grids. As a result, some boundary cells can be contained two numerical conditions such as the flow and solid conditions, where the special treatment is needed to simulate such physical characteristics. The HLLC approximate Riemann solver, a Godunov-type finite volume method, is employed to discretize the advection terms in the governing equations. Also, the TVD-WAF method is applied on the Cartesian cut-cell grids to stabilize numerical results. Present method is validated for the rectangular dam break problems. Initially, a conventional grid is constructed with the Cartesian regular mesh only and then applied to the dam-break flow simulation. As a comparative simulation, a cut-cell grids are applied to represent the flow domain rotated with arbitrary angles. Numerical results from this study are compared with the results from the case of the Cartesian regular mesh only. A good agreement is achieved with other numerical results presented in the literature.

This paper presents the elastic buckling of smart lightweight column structures integrated with a pair of surface piezoelectric layers using artificial intelligence. The finite element modeling of Smart lightweight columns is found using $ANSYS^{(R)}$ software. Then, the first buckling load of the structure is calculated using eigenvalue buckling analysis. To determine the accuracy of the present finite element analysis, a compression study is carried out with literature. Later, parametric studies for length variations, width, and thickness of the elastic core and of the piezoelectric outer layers are performed and the associated buckling load data sets for artificial intelligence are gathered. Finally, the application of soft computing-based methods including artificial neural network (ANN), fuzzy inference system (FIS), and adaptive neuro fuzzy inference system (ANFIS) were carried out. A comparative study is then made between the mentioned soft computing methods and the performance of the models is evaluated using statistic measurements. The comparison of the results reveal that, the ANFIS model with Gaussian membership function provides high accuracy on the prediction of the buckling load in smart lightweight columns, providing better predictions compared to other methods. However, the results obtained from the ANN model using the feed-forward algorithm are also accurate and reliable.

In order to scrutinize what realism really means, this paper is to analyze and compare the major realistic plays of Yun Jo-byeong of Korea with the earlier realistic ones of Bernard Shaw of England. As all the scholars concerned admit, Shaw offered reality in all of his plays: social, political, economic, religious. He was a didact, a preacher who readily acknowledged that the stage was his pulpit. Though he preached socialism, creative evolution. the abolition of prisons, real equality for women, and railed against the insincerity of motives for war, he did so as a jester in some of the finest comedy ever written. Shaw brought serious themes back to the trivialized English stage, creating a body of drama that left him second to none among twentieth century dramatists. Today, evolution and creationism and Shaw's ideas on creative evolution and the Life Force remain timely issues. As for Yun Jo-byeong who has written many realistic plays lately, he is known as a major realist in Korea. But his realistic plays are more symbolic, poetic, and private than Shaw's. As a result, Korean realism has not been so flourished in Korea as in England. Therefore, we Korean playwrights who want to write really realistic plays should try to study Shaw's realism more closely than ever.

There is disagreement, among researchers, on the benefits of corrective feedback on L2 learners' written output. Some scholars advocate the usefulness of corrective feedback while some claim that error correction is ineffective and even harmful. So far, however, research outcomes cannot settle this debate. Based on this debate, this study examines whether there is a difference among diverse types of feedback on the effects of L2 learners' writing improvement. This study found that teacher's direct feedback was more effective than any other types of feedback on the effect of participants' writing improvement. In particular, teacher's direct feedback helped their improvement on grammar, mechanics, and form. Among the types of peer feedback, self-correction was the most effective. In teacher feedback, form-focused feedback had more effects than content-focused feedback, but no difference with regard to peer feedback. In addition, teacher's content-focused feedback was more effective than peer's content-focused feedback. Overall, in all types of feedback, teacher feedback was more effective than peer feedback. However, direct (form-focused) feedback was the most effective in teacher feedback, and self-correction in peer feedback. The least effective feedback in both teacher and peer feedback was indirect (form-focused) feedback, which is simple underlining of errors.
