  • The purpose of this study is to find a scheme to scale down the KMA (Korea Meteorological Administration) digital precipitation maps to the grid cell resolution comparable to the rural landscape scale in Korea. As a result, we suggest two steps procedure called RATER (Radar Assisted Topography and Elevation Revision) based on both radar echo data and a mountain precipitation model. In this scheme, the radar reflection intensity at the constant altitude of 1.5 km is applied first to the KMA local analysis and prediction system (KLAPS) 5 km grid cell to obtain 1 km resolution. For the second step the elevation and topography effect on the basis of 270 m digital elevation model (DEM) which represented by the Parameter-elevation Regressions on Independent Slopes Model (PRISM) is applied to the 1 km resolution data to produce the 270 m precipitation map. An experimental watershed with about $50km^2$ catchment area was selected for evaluating this scheme and automated rain gauges were deployed to 13 locations with the various elevations and slope aspects. 19 cases with 1 mm or more precipitation per day were collected from January to May in 2013 and the corresponding KLAPS daily precipitation data were treated with the second step procedure. For the first step, the 24-hour integrated radar echo data were applied to the KLAPS daily precipitation to produce the 1 km resolution data across the watershed. Estimated precipitation at each 1 km grid cell was then regarded as the real world precipitation observed at the center location of the grid cell in order to derive the elevation regressions in the PRISM step. We produced the digital precipitation maps for all the 19 cases by using RATER and extracted the grid cell values corresponding to 13 points from the maps to compare with the observed data. For the cases of 10 mm or more observed precipitation, significant improvement was found in the estimated precipitation at all 13 sites with RATER, compared with the untreated KLAPS 5 km data. Especially, reduction in RMSE was 35% on 30 mm or more observed precipitation.

  • This study requires a strict distinction between the sculptures we call 'Jangseung' because their origins, history, or functions are different from each other. Therefore, a theoretical consideration was made through the origin and history of Jangseung. Currently, Jangseung is widely distributed throughout the country, but the Honam region shows the largest distribution, and 73 out of 167 locations nationwide remain in the Chungcheongnam-do region. Among these, there are 54 stone jangseungs in Jeollanam-do, 37 in Jeollabuk-do, and 19 in Jeollabuk-do. In particular, the original shape of the stone jangseungs in the Honam region is well preserved, and as a center of the agricultural economy, the jangseung culture is active in this region. It was popular, and many stone jangseungs were built in the Daejeon area amid social changes in the late Joseon Dynasty. However, in the South Chungcheong region, there is not much culture about stone jangseungs, but there is a village meaning and consciousness that stone jangseungs have, but it is true that research on stone jangseungs is insufficient in various aspects. Among them, the form of the stone jangseung built between the 17th and 19th centuries is a sculpture that contrasts with the wooden pillar-type jangseung that is common in the central region, and shows the simple mentality of the people of the Daejeon region without any embellishment. Through Jangseung, we were able to discover the unconscious and potential creativity of national aesthetic consciousness. Therefore, the purpose is to trace the change process of the stone jangseung in the Daejeon area, investigate the functional aspects of this structure, and based on this, examine the various current status and locational characteristics of the so-called stone jangseung. In addition, the wooden figures and stone statues that are now commonly known as Jangseung were each erected in different times and for different reasons. Centering around Daejeon, the study attempted to research and identify representative stone monuments or 'stone jangseungs' that appear as stone statues, and even suggest their form through locational characteristics and suggestions. As a result, traditional jangseungs have changed in various forms as times change, reaching their present form, and the religious elements of modern jangseungs made and erected today are weakened or disappeared, and are used as symbolic symbols or sculptures of tradition. Although it has lost its traditional function as an object of village faith, it functions as a milestone or sign at the entrance to a village or event site, or as an exhibition in special places. It was found that the modern jangseung is a representative symbol of Korean traditional culture and is being re-created as an artistic sculpture that expresses common, simple, natural beauty and humor. Therefore, through this study, based on more specific and systematic investigation and research on the jangseung, it was materialized into a more developed form considering its utilization plan to prevent miscellaneous spirits from entering the village through the currently existing stone jangseung and to improve the spatial space accordingly. It is believed that what is located at the entrance can greatly convey its meaning. Therefore, it is judged necessary to maintain the strong characteristics of folk religion without the sophistication of foreign religions for various deities.
