Purpose- This research's purpose is to give implications on how to increase employee satisfaction and organizational commitment of Korean employees using internal marketing. To do that this study analyzes relationships among variables and analyses mediating effect of satisfaction. Also, this study wants to analyze economic performance change of business as a moderator so group comparison between an economic slump and economic recovery is included. Research design, data, and methodology- To analyze relationships among internal marketing, employee satisfaction and organizational commitment of Korean employees, this study used the 7th KRIVET's HCCP data of employee and firm's financial statements data. And conducted CFA, SEM and group comparison analysis by using AMOS 21. Result- According to the empirical results, employee satisfaction mediates between internal marketing and organizational commitment. However, trust was the only significant antecedent that give a positive influence on employee satisfaction. And employee satisfaction increases organizational commitment. Also, economic performance change of business does significantly deteriorate relationships. Conclusion- Based on this study result, implications to manage the organizational commitment of Korean employees are discussed. Especially, the effect of employee satisfaction and trust discussed. Also, economic performance group which is an economic slump and economic recovery differentiation is highlighted. Therefore the cautious approach is needed in managing employee attitude to job and organization is needed

In this study, CS-H walls with large stiffness were constructed using geosythetics for use in excavation at a depth of 30 m or more in Korea, and in order to construct the CS-H wall suitable for the site conditions, the formulation was examined according to the change in the mixing ratio of the geosythetics and the slump value (slump flow) and as a result, in the target slump 180 mm and the slump flow 500 mm, the formulation was confirmed to meet the mechanical properties such as the initial bending strength, the long-term behavior, and the elastic modulus as well as the economic efficiency. However, in the slump flow 600 mm, the result indicated that the formulation was inappropriate in the mechanical properties such as the initial bending strength, the long-term behavior, and the elastic modulus.

China has been experiencing high economic growth along with massive change in its industrial structure. How will the industrial structure change affect the Chinese economy? Similar changes were observed by Japan, when the Japanese banking system fell into a structural failure in terms of the inability to respond to the paradigm shift from "catching up" to "frontier economy." This paper is undertaken to highlight the lessons that China can learn from Japan's prolonged financial slump. We point out that big cities in China have already shifted to frontier economy and major provinces are on the same trend. We argue that in spite of economic reform reshaping the Chinese banking system, the financing pattern of state owned commercial banks (SOCB) is not in line with the industrial change. The Chinese banking system should be overhauled or transformed to respond to the increasing uncertainty along with the paradigm shift. Otherwise, China may fall into the same dilemma that Japan had faced in its industrial structure change.

Domestic construction companies are suffering from financing difficulties in the wake of the economic slump in Korea and abroad. During this economic slump, real estate investment trusts (REITs), facilitators for improving financing and stimulating construction businesses, have increasingly expanded since their introduction in 2001. However, in terms of growth speed and marketing size, Korean REITs are falling behind those of other nations. The purpose of this study is to suggest a method for composing a portfolio using the Markowitz portfolio selection model to stimulate REITs. The main contents are as follows. First, a comparative analysis was conducted of increased REIT profit with the application of the Markowitz model and the average REIT profit rate from July 3, 2007, to July 21, 2008, during the investment analysis periods. The results showed that the total profit rate from the Markowitz model was about 10% higher than the average REIT profit rate. Second, the sensitivity was analyzed according to the portfolio's data-gathering and replacement cycle to measure the optimum cycle and yield. The six-mouth profit data collection period showed about 16% higher profits with the Markowitz model than with the REITs. The two-week portfolio change period resulted in about 11% higher profits with the Markowitz model than with the REITs.

The CGS method is non-discharge replacement method improving ground stiffness by the effect of static compaction with injecting very low slump mortar into ground, and is applied for increasing bearing capacity and filling ground cavity by lifting or restoring differential settled structures and preventing differential settlement. This paper suggests design of ground improvement and construction case history for civil engineering structures by CGS method. This method can be used for reinforcing soft ground and liquefaction of loose sandy soil. This method was used in SongDo area in Incheon Economic Free Zone due to its low vibration of ground while it can improve the soft soil where underground structures(subway and box culvert) are already existed.

An experimental study os performed to examine the feasibility of using wastes steel furnace slag construction materials and its utility as a replacement for the natural resources to prevent the economic loss was investigated. A half factorial exprements was performed with the variables of W/C ratio, S/A, Coarse aggrigate/Slag ratio and slump as a preliminary study for optimum mix design of concrete. The results show that the W/C ratio and Slump ratio are the most important factor to the concrete strength. The substitute of waste Slag up to 100% has little influence, saying that it can substitute the coarse aggregate without damaging the concrete properties.

Recently, The economic growth has increased carbon dioxide emissions. so, It is caused by social problem to environmental damage and human health due to global warming. Accordingly, The method solution is to the amount of cement and to use industrial by-product such as Blast furnace slag, Fly Ash, and Red-mud. Thus, The purpose of this study is to analyze the physical property of concrete with red-mud. So, this study carries out the basic performance test of concrete such as, air content, slump, and compressive strength. In this work test is conducted according to sequence of materials using concrete twin mixer.

In this study the pilot test of CGS as injection method by low slump mortar was performed and the results were analyzed in order to find out the application of this method and effect of settlement restraint. The site far pilot test is adjacent to apartments supported by pile foundations. Sand drain method was performed previously as countermeasures against settlement, but settlement occur continuously because this ground is very soft. Site investigations such as SPT, DCPT and vane shear test were performed to determine the characteristics of ground improvement. Field measurements and FDM analysis were performed on purpose to find out the displacement of ground during injection works. From the results of this study, CGS method can be optimized by the control of diagram, space, depth, injection material, and injection pressure. CGS improved soft ground compositely by the bearing effect of CGS columns and reinforcement of adjacent ground. Considering that increase of N value is about 2.1, CGS can be considered as an effective method to increase the bearing capacity as well as to stop the settlement of soft ground. It is also expected to be economic and effective in improvement of ground when it is used in applicable sites.
