  • Land suitability assessment(LSA) is a useful method to assess land characteristics according to its physical, locational, and environmental characteristics, and then to classify it into several categories based on its usability and the necessity for conservation. Therefore, the credibility of this assessment result depends on the rationality of assessment method such as computation of suitability values and the criteria of ranking the land grade. This study focused on identifying problems in current LSA method by critically reviewing it, and aimed to suggest a suitable method for the assessment of land suitability. As a alternative method in this study, linear transformation method was used for scoring factors instead of critical values and the weight for each assessment factor. and all values of those factors were added to produce comprehensive suitability values. Those values were ordered and categorizied with suitability level based on the ratio of square measure. After comparing existing LSA method to the suggested alternative method, it is concluded that the alternative method was more suitable to assess the characteristics of lands than existing LSA method. This method was also suitable to represent the characteristics of various assessment factors. Field survey using satellite image clearly revealed the suitability of the alternative method compared to an existing method of land assessment. Furthermore, the alternative method of grading the land suitability improves the problem of using standardiZiation method and gives more flexibility, which makes this method very rational.

  • For the purpose of enhancing usability of NWP (Numerical Weather Prediction), the quantitative precipitation prediction scheme was suggested. In this research, precipitation by leading time was predicted using 3-hour rainfall accumulation by meso-scale numerical weather model and AWS (Automatic Weather Station), precipitation water and relative humidity observed by atmospheric sounding station, probability of rainfall occurrence by leading time in June and July, 2001 and August, 2002. Considering the nonlinear process of ranfall producing mechanism, the ANN (Artificial Neural Network) that is useful in nonlinear fitting between rainfall and the other atmospheric variables. The feedforward multi-layer perceptron was used for neural network structure, and the nonlinear bipolaractivation function was used for neural network training for converting negative rainfall into no rain value. The ANN simulated rainfall was validated by leading time using Nash-Sutcliffe Coefficient of Efficiency (COE) and Coefficient of Correlation (CORR). As a result, the 3 hour rainfall accumulation basis shows that the COE of the areal mean of the Korean peninsula was improved from -0.04 to 0.31 for the 12 hr leading time, -0.04 to 0.38 for the 24 hr leading time, -0.03 to 0.33 for the 36 hr leading time, and -0.05 to 0.27 for the 48 hr leading time.

  • As Telepresence has emerged as a key collaboration tool for supporting trade business, the need for using Telepresence has also been increased in the foreign countries. In this context, we has studied an exploratory research to analyze how staffs-in-charges of trade support authority, exhibition & convention center and SME(Small and Medium-Size Enterprise) perceive the general concept of Telepresence, the necessity, feasibility, business values and expected problems of Telepresence's adoption and use. The finding indicated that there seemed to be significant differences between the necessity and the feasibility of Telepresence adoption and use. In addition, they were anticipating some problems when building Telepresence. Major reasons are incompatibility between Telepresence systems, lack of usability and difficulties of fixing a rental fee. The results of the perception analysis also showed that Telepresence would positively influence on creating business value. The analysis revealed that the core factors of the successful adoption and use of Telepresence are stable network environment, awareness and accessability, and education and promotion. Through the perception analysis, I came up with the core factors to implement Telepresence successfully and use it properly. And the fact that I presented the guideline to build Telepresence for SME makes this study meaningful.

  • Paper currency is a cultural symbol sign representing identity of a nation as well as a tool of barter system and a measure of value. The purpose of this study is to analyze the design characteristics shown in the pattern of the paper currencies of advanced countries and Korea and to make comparative analysis of the image type of each nation as a cultural code. The results show that 1) the usability of paper currency design was evaluated by denominations, size type, color, braille system and the paper currencies of Switzerland and EU were judged superior to those of the other counties. 2) The national image type represented paper currencies was classified as 'state oriented type' and 'culture & art oriented type'. The countries of Korea, U.S.A, Japan etc. have on the paper currencies the ruling class who contributed to organizing the national system foundation emphasizing their nationalism. In the case of European countries, their paper currencies reveal a variety of citizen who have contributed to art, science, music, architecture without distinction of gender and this fact puts an emphasis on egalitarianism and equality of both senders and importance or cultural art. 3) Paper currency design of Switzerland, Netherlands, France, U.K. was visualized as an art work with utilization of work-type subject, brilliant color, CG technique, unique layout etc. This study provides us with a valuable opportunity to examine the present state of the Korean paper currencies design in Comparison With those of the world's advanced countries. It is expected that this study could be a resource material for new paper currency design and emphasize the importance of the paper currencies representing a national image as a cultural design.

  • This study were conducted the particle-size analysis on 57 blue pigments to understand the step distribution characteristics of blue pigments made out of Azurite by using Malvern's Mastersizer 2000. As the result, most of the conventional blue pigments in Korea, Japan, and Chinese showed good granularity step separation except for few, and the smaller the particle, the more the Span value increased and the wider the granularity distribution range. On the basis of Friedman and Sanders's Grain size, most of the pigments were sand size to silt size. 72.2% of B-100 was clay size and 2.5% of A-14 was gravel size. Even the same components can differ by the grain size directly affecting the important property such as color formation, oil absorption, specific gravity, usability, etc. so the information about the granularity distribution would be used for basic data to deal with natural pigments.
