Big Data is now seen as a major asset in the company's competitiveness, its influence in the future is expected to grow. Companies that recognize the importance are already actively engaged with Big Data in product development and marketing, which are increasingly applied across sectors of society, including politics, sports. However, lack of knowledge of the system implementation and high costs are still a big obstacles to the introduction of Big Data and systems. It is an objective in this study to build a Big Data system, which is based on open source Hadoop and Hive among Big Data systems, utilizing POS sales data of small and medium-sized offline markets. This approach of convergence is expected to improve existing sales systems that have been simply focusing on profit and loss analysis. It will also be able to use it as the basis for the decisions of the executive to enable prediction of the consumption patterns of customer preference and demand in advance.

This is the time that political effort is required to encourage domestic companies to expand overseas facing internationalization. Regarding exportation, not only major companies, but SMEs also should be greatly concerned. As for the case of SMEs, it has been thought to be as inferior brand image in domestic market, but as world market such as China is very huge and diverse. There is high possibility of increasing in export of SMEs with concerns. To strengthen the competitiveness and develop the potential of SMEs, promoting renovation of system is a must, over the renovation of skill or management. It is important to figure out the degree of contribution and route for exports, since every company has different aspects. Therefore, the purpose of this study is to calculate the degree of contribution of Korean SMEs, and to find further improvements by understanding export route. It also tries to suggest proper policies to vitalize SME's export.

The stress dependence of ultrasonic wave velocity is known as the acoustoelastic effect. This effect is useful for stress monitoring if the acoustoelastic coefficient of a subject medium is known. The acoustoelastic coefficients of metallic materials such as steel have been studied widely. However, the acoustoelastic coefficient of concrete has not been well understood yet. Basic constituents of concrete are water, cement, and aggregates. The mix proportion of those constituents greatly affects many mechanical and physical properties of concrete and so does the acoustoelastic coefficient of concrete. In this study, influence of the water-cement ratio (w/c ratio) and the fine-coarse aggregates ratio (fa/ta ratio) on the acoustoelastic coefficient of concrete was investigated. The w/c and the fa/ta ratios are important parameters in mix design and affect wave behaviors in concrete. Load-controlled uni-axial compression tests were performed on concrete specimens. Ultrasonic wave measurements were also performed during the compression tests. The stretching coda wave interferometry method was used to obtain the relative velocity change of ultrasonic waves with respect to the stress level of the specimens. From the experimental results, it was found that the w/c ratio greatly affects the acoustoelastic coefficient while the fa/ta ratio does not. The acoustoelastic coefficient increased from $0.003073MPa^{-1}$ to $0.005553MPa^{-1}$ when the w/c ratio was increased from 0.4 to 0.5. On the other hand, the acoustoelastic coefficient changed in small from $0.003606MPa^{-1}$ to $0.003801MPa^{-1}$ when the fa/ta ratio was increased from 0.3 to 0.5. Finally, it was also found that the relative velocity change has a linear relationship with the stress level of concrete.

The recent plant order of oversea in domestic engineering and Construction Companies have been growing since 2003. In 2006, the total order came out 2.54 billion dollar. And in a quarter of 2007, the Ministry of Commerce announced that total order already came out 900 million dollar. They expect that the plant industry in the global market will be grown more in near future. However, even though there is growing plant businesses in oversea specially focused on the Middle East area, the domestic large engineering and Construction Company now face up the shortage of specialty manpower. Moreover, the domestic small and medium enterprises have same problems as large companies have. The plant construction industry is expanding rapidly, but the supply of specialty manpower can not follow its growing business. Also, most new supplied manpower is the person who graduated recently and received the degree in the different civil engineering track other than the plant major track, they are required to be re-educated. So, it is unable to deploy in short time. Also, there is shortage of manpower in the Construction Management financing division. Consequently, this project will study the efficient method of training for specialty manpower, provide the solutions.
