  • The coupled model (SMART) of dynamic meteorology model and particle dispersion model was developed. The numerical experiment on the relationship between change of land use and diffusion behavior in complex terrain was carried out using this model. It tried to investigate the change of particle diffusion behavior and local weather under the condition in which land-land breeze and sea breeze and mountain breeze intermingled. The numerical experiment results are as follows; 1) The more complicated local circulation field of the interaction of sea breeze, mountain breeze and Land -land breeze is formed. Then, the region circulation in which the urbanization is specific by location of the region is strengthened and is weakened. 2) Though in the region with dominant sea breeze, Land-land breeze does not appear directly, the progress of the sea wind to the inland is affected. 3) In the prediction of the air diffusion, emission high quality and accurate information of the emission site are important. That is to say, the dispersion predicting result which emission high quality and small error of the site perfectly vary for Land - land breeze in the effect may be brought about.

  • Domestic timber comsumption has increased dramatically in the past few decades in this country. In addition, there is increasing demand for recreational opportunities in the forest areas and concern for watershed management and soil conservation. However, it is difficult to satisfy these demands for forest resources because many of woodland owerners who make such demands possible move from mountain villages to modern cities. Therefore, whether or not it is in the public interest to invest in rurbanization is a central policy question. This is a case study which deals with mountain village problems for making forest resources.

  • The remaining Joongjaesil(中齋室)-type pavilions in the eastern part of the Jirisan Mountain area showed more complex characteristics than those in the western part. The front number of kan(間) had two, three, and four kan (間) types, but the number of kan on the side was consistent with two regardless of the number of kan on the front. The pavillion is classified into 'central type', 'towards the backward type', and 'expanded by backwards type' according to the location of Joongjaesil. Joongjaesil's size, which characterizes the characteristics of Joongjaesil-type Pavilion, is related to the building's front number of kan. Front number of kan. When this space was increased by one space to four spaces, Joongjaesil must have two spaces. The pavilion with four bays in front showed the characteristics of being concentrated in Sancheong and Jinju, the eastern part of the Jirisan Mountain area. In the eastern region, many high pavilions remain, and the upper structure of the pavilion was insignificant, but the flat shape and public construction showed strong locality.

  • This study was carried out to provide basic information for standard cultivation guideline of Korean mountain cultivated ginseng (Panax ginseng). Environmental conditions, soil properties, growth process, cultivation methods and sowing timing were investigated in cultivations of Korean mountain cultivated ginseng in Korea (18 region in 9 province). Most of Korean mountain cultivated ginseng was cultivated to north, north-east, east or north-west direction in broad-leaved forest, IV age group, and 500~1,000 trees/ha. Elevation was below 500 m and slope was below $25^{\circ}$ in cultivation. There were significant differences in soil properties by region and cultivation based on organic matter (3.43~24.07%) and pH level (3.8~5.7). Sprouting, leaf unfolding, flowering, fruiting, red ripening, fruit drop and leaf drop of Korean mountain cultivated ginseng was investigated in cultivation. The results show that it took 98 days on average for the whole growth process. There were two methods, sowing and transplant for cultivation. Sowing methods were classified in sowing after opening-testa treatment and direct sowing. and it was 70% and 30%, respectively.

  • The investigation of driving mechanism for the formation of tropical night in the coastal region, defined as persistent high air temperature over than 25$^{\circ}C$ at night was carried out from August 14 through 15, 1995. Convective boundary layer (CBL) of a 1 km depth with big turbulent vertical diffusion coefficients is developed over the ground surface of the inland basin in the west of the mountain and near the top of the mountain, while a depth of thermal internal boundary layer (TIBL) like CBL shrunken by relatively cool sea breeze starting at 100 km off the eastern sea is less than 150 m from the coast along the eastern slope of the mountain. The TIBL extends up to the height of 1500 m parallel to upslope wind combined with valley wind and easterly sea breeze from the sea. As sensible heat flux convergences between the surface and lower atmosphere both at the top of mountain and the inland coast are much greater than on the coastal sea, sensible heat flux should be accumulated inside both the TIBL and the CBL near the mountain top and then, accumulated sensible heat flux under the influence of sea breeze circulation combined with easterly sea breeze from sea to inland and uplifted valley wind from inland to the mountain top returning down toward the eastern coastal sea surface should be transported into the coast, resulting in high air temperatures near the coastal inland. Under nighttime cooling of ground surface after sunset, mountain wind causes the daytime existed westerly wind to be an intensified westerly downslope wind and land breeze further induces it to be strong offshore wind. No sensible heat flux divergence or very small flux divergence occurs in the coast, but the flux divergences are much greater on the top of the mountain and along its eastern slope than on the coastal inland and sea surfaces. Thus, less cooling down of the coastal surface than the mountain surface and sensible heat transfer from warm pool over the coast into the coastal surface produce nocturnal high air temperature on the coastal inland surfaces, which is not much changed from daytime ones, resulting in the persistence of tropical night (nocturnal thermal high) until the early in the morning.

  • The Baekdudaegan Mountain Range is a backbone of the Korean Peninsula which carries special spiritual and sentimental signatures for Koreans as well as significant ecological values for diverse organisms. However, in spite of importance of this region, the forests of Baekdudaegan have been damaged in a variety of human activities by being used as highland vegetable grower, lumber region, grass land, and bare land, and are still undergoing destruction. The existing researches had determined the details of the damage through on-site and recent observations. Such methods cannot provide quantitative and integrated analysis therefore could not be utilized as objective data for the ecological conservation of Baekdudaegan forests. The goal of this study is to quantitatively analyze the forest damage in the Baekdudaegan preservation region through land cover categorization and change detection techniques by using satellite images, which are 1980s, and 1990s Landsat TM, and 2000s Landsat ETM+. The analysis was executed by detecting land cover changed areas from forest to others and analyzing changed areas' spatial patterns. Through the change detection analysis based on land cover classification, we found out that the deforested areas were approximately three times larger after the 1990s than from the 1980s to the 1990s. These areas were related to various topographical and spatial elements, altitude, slope, the distance form road, and water system, etc. This study has the significance as quantitative and integrated analysis about the Baekdudaegan preservation region since 1980s. These results could actually be utilized as basic data for forest conservation policies and the management of the Baekdudaegan preservation region.
