To analyze their isoflavones contents by HPLC analysis during two years on 60 collected old local traditional soybean varieties from various districts of Korea was conducted. There was a yearly variation in the seed isoflavon concentrations. The total contents on 5 isoflavones were in the range from 16.21mg/g to 25.21 mg/g and from 6.47 mg/g to 15.44 mg/g, in 1997 and 1998, respectively. Collected soybean from Gunsnsi-1(25.21 mg/g) in 1997 and from Gangjingun-3 (16.50 mg/g) in 1998 showed the highest amount of isoflavones as compared with other collected soybean varieties. The highest amount among 5 isoflavones was genistin as 48.45% and 49.73%, in 1997 and 1998, respectively, indicating the genotypic variation in seed isoflavon contents of local soybean cultivar. Our data suggest that it may be feasible for improving soybean variety with higher antioxiadtive activity and substances.

Purpose - This study aims to analyze the relationship between trends in innovative EU industries and market distribution in smaller emerging markets under an open economy. Research design, data, and methodology - Although innovation was well-distributed, due to socio-economic factors following European integration, CEE had not achieved sustainable economic growth. However, this paper analyzes the differences among changes in CEE innovation for smaller emerging markets dominated since 2000. Market distribution has facilitated new markets for innovative industries, according to EU surveys and economic indicators. Results - The dominance of the local industrial market distribution has deterred innovation investment the survey shows that innovation investment has been shrinking, despite the EU's open innovation policy for CEE employment and R&D. For the CEE case, there were expectation gaps and uncertainty about whether to use the new distribution dominance or TNCs' innovation in smaller emerging countries without local industrial innovation. Conclusions - Innovation generates market growth and distribution power however, small growth requires stimulation, and creativity and innovative edge need further focus in local public and corporate strategy.

In this paper development of on-line data visualization program is described and some examples of data postprocessing are shown. The program is written in JAVA language and runs as a JAVA applet on the web browser such as Internet Explorer or Firefox. Remote users can use the program to visualize and analyze their own flow data by accessing the program server through the internet and loading data files in proper formats from their local computers. This paper describes briefly about algorithms for data visualization, structure and available functions of the program, and web sever system. The mechanism of how the JAVA applet can access and process local data files and relevant coding techniques are explained as well. Also explained is what is required for the remote users and client computers to access the program on-line. Some visualization examples performed on a local computer are illustrated by accessing the server remotely.

The study aims to examine the brand image for developing place name and local brand to create effective development. The data were collected purposive sampling technique by face-to face interview. 154 of resident and 152 of visitor in Seocheon county were used for analysis. Collected data were analyzed by ANOVA and factor analysis. The study found that it was deducted as passionate, comfortable, conservative image through exploring factor analyze that was about brand image's individuality in Seocheon county. And, it had an order that was Konmoe (29.2%), Solli(20.8%), Soya(17.5%) on resident, Konmoe(30.9%), Solli(19.7%), Munitgol(16.4%) on visitor, in place name favorable degree of the nature village. Results suggest that place name be utilized by brand individuality for place marketing effectively.

GA (Genetic Algorithms) are efficient for searching for global optima but may have some problems such as premature convergence, convergence to local extremum and divergence. These phenomena are related to the evolutionary operators. As population diversity converges to low value, the search ability of a GA decreases and premature convergence or converging to local extremum may occur but population diversity converges to high value, then genetic algorithm may diverge. To guarantee that genetic algorithms converge to the global optima, the genetic operators should be chosen properly. In this paper, we analyze the effects of the selection operator, crossover operator, and mutation operator on convergence properties, and propose the sweeping method of mutation probability and elitist propagation rate to maintain the diversity of the GA's population for getting out of the premature convergence. Results of simulation studies verify the feasibility of using these sweeping operators to avoid premature convergence and convergence to local extrema.

The objective of this paper is to define local optimization algorithms (LOA) to solve Resource-Constrained Project Scheduling Problem (RCPSP) and analyze the performance of these algorithms. By representing solutions with activity list, three primitive LOAs, i.e. forward and backward improvement-based, exchange-based, and relocation-based LOAs are defined. Also, combined LOAs integrating two primitive LOAs are developed. From the experiments with standard test set J120 generated using ProGen, the FBI-based LOA demonstrates to be an efficient algorithm. Moreover, algorithms combined with FBI-based LOA and other LOA generate good solutions in general. Among the considered algorithms, the combined algorithm of FBI-based and exchangebased shows best performance in terms of solution quality and computation time.

The purpose of this study is to analyze the internal factors that influence the performance of local government hospitals in Korea. There are 34 hospitals in korea as of 2008. Among these hospitals 5 are profit-making and the other loss-making in terms of profitability. Data was collected by Institute of local government hospital union. The major findings of this study was as follows : Firstly, 7 hospitals are high level, over than 100% of fixed ratio. But that result was better than the other study 5 years ago. Secondly, 29 hospitals are bellow 85% of bed occupancy rate. There are a number of hospitals didn't use the facilities and the personnel cost in total costs are high. And lastly, as a result of multiple regression analysis, the factors had on significant effect on normal profit to total assets are personnel cost(-), liability to total assets(-), average length of stay(-), outpatient visits to inpatient days(-). In conclusion, to improve the profitability of hospitals, the efforts to reduce personnel cost and to increase bed occupancy rate.

Local deformations in back filling materials of two sands and one glass bead with different particle shapes behind a rigid retaining wall were studied. Two kinds of boundary conditions were compared: active wall translation and active rotation of the wall about its toe. Effect of the speed of active wall translation was also investigated. The digital image correlation method was used to analyze local deformation developments inside the materials. Test results showed that particle shape and density mainly influence the inclination angle and width of the shear band. The general shear band pattern is strongly dependent on the wall movement mode, while it was little influenced by particle shape. Within a limited range of wall speed in this study, shear band became wider and local deformation became larger with increase of wall speed.
