Suhainmyuldo(수하인물도) is a kind of picture which express a person under the tree and is known to be transmitted from the Middle Asia. The origin of this kind of expression is assumed to be from Iykshini(=Iygsha), the fairy of tree, in India of from the 'Tree of Life' in W. Asia, and they had in fluenced on the craft art design of Chinese art. However, Chinese art had already developed the motif of this kind in its unique way. For example, Jookrimchilhundo(죽림칠현도: seven wise men in bamboo forest), during Six Dynasty. The tree of life(arbor vitae, lignum viate), the origin of the Painting of figure under a tree(수하인물도), was spreaded in several regions around the center of Mesopotamia early, and them transmitted to Sasan dynasty of Persia, even to Islam, Byzantine, Romanesque, ancient East Asia. The mural painting found in the 4th Tongu Ogoe tomb, which was created after the 5th Tongu Ogoe tomb, used Obangsaek more than the 5th tomb painting did. (The term Obansaek refers to the five Korean traditional colors consisted of yellow, blue, white, red and black) The mural painting on the 4th Ogoe tomb employed distinct technique to depict an object in a certain color by painting the surroundings with different primary colors, making the painting look more exotic and mysterious.

The dynamic characteristics of a condenser are numerically studied for the control of air-conditioning systems. The important factors, such as the refrigerant flow rate and refrigerant temperature, air velocity and air temperature at the condenser inlet, are incorporated into the analysis. This study was focused on the analysis of dynamic responses by transfer function method in the condenser. Block diagrams were made through analytic transfer function, and dynamic responses are evaluated on Bode diagrams in the frequency response. These results may be used for determining an optimum design parameters in an actual component and total systems. Also, the mathematical models, frequency response and steady state response may be used to increase understanding, to obtain useful information for its commercialization, to evaluate the hardware and the optimum design parameters, the design control system and to determine the best controller setting for the refrigeration and air conditioning systems.

The objective of the present study lies in providing the method to construct the precision population-statistical map for statistical demographics making full advantage of GIS and the national census data in an attempt to improve accuracy and reliability of population estimation applicable for a variety of location analysis. More specifically, it adopts the multiple regression analysis by segmented land use type(biotope) taking into account that the land use diversified as residence, commercial and office areas has the close connectivity and interdependence with population. Based on the analyzed result above, the study finalizes the modeling to construct demographic map with higher precision by prioritizing the population density by weight value and then re-distributing the population according to jurisdictional dong's and types of use for the land. The study consequently is expected to be conducive to improving precision and reliability rather than the existing method for population estimation widely acceptable thus far.
