농산물의 가격은 해마다 변화가 있으며, 가격변화는 수급불균형이 주요한 원인이다. 배추 생산량 예측모델에서 주로 사용되는 자료는 경사 면적 산출이 불가능한 지적성과를 사용하고 있다. 이런 이유로 고랭지 등의 경사지에서 재배되고 있는 밭작물의 수급 예측의 정확도가 떨어져 가격 폭등과 폭락이 반복되고 있는 상황이다. 따라서 이 연구에서는 고랭지 등 경사지를 대상으로 2차원 자료인 지적 성과와 3차원 자료인 라이다데이터를 분석하여 동일지역에서의 데이터 상호간 경작 면적 차이를 비교해 보는 실험을 실시하였다. 이와 함께 경사도 증가에 따른 면적의 변화율을 계량적으로 분석해 낼 수 있는 회귀 모델을 제시하여 지적도와 같은 2차원 평면성과에 의한 경사지 면적 산출의 신뢰도를 향상시킬 수 있는 대안적 방법론을 제시하였다. The price of agricultural products has changed from year to year, the m ajor c ause o f price fluctuation is the imbalance of supply and demand. Materials which are mainly used in korean cabbage production volume is the forecast model, using the cadastral result, slope calculation is impossible to achieved. For this reason, this implies the drastic decrease of prices and the prediction of supply and demand of field crops that is cultivated in a highland slope area, this situation is being repeated. Therefore, the target area of this research is the slopes of high land, by using 2D and 3D Lidar data for the analysis of the cultivated area. Experiment was carried out in the same area to compare the data differences. The rate of change in the area of slope is quantitatively increasing presented by the regression model. An alternative methodology that can improve the reliability of the calculated slope area using 2D is through cadastral map.

The purpose of this study is to examine the effects of company workers' motives to participate in leisure sports on their consumption behaviors. 600 panels from Internet surveys were collected as the population of the study. The method of the statistical analysis used in this study, were correlation and multiple regression analysis through the SPSSWIN 12.0 statistics program. As a result of these data analysis, the conclusions of this study are as follows. First, it is found that all the secondary factors of company workers' motives have an effect on media information consumption, in the order of external ostentation, social relationship, body form management, health, and purification. Of these, purification has a negative effect. Second, the factors have an effect on experiential tourism consumption, in the order of external ostentation, purification and social relationship; the last one has a negative effect. Third, the factors of external ostentation and social relationship only have an effect on supplies consumption, in the order of external ostentation and social relationship. Fourth, all the factors of the said motives have an effect on personal participation consumption, in the order of purification, external ostentation, body form management, health and social relationship. Fifth, all the factors of the motives have an effect on sports web site consumption, in the order of body form management, social relationship, health, external ostentation and purification. Sixth, all the factors of the motives except for social relationship have an effect on stadium watch consumption, in the order of external ostentation, health, body form management and purification.

We report a case of clear cell acanthoma occurred in a 61 year old man. He developed a brownish bean sized nodule on the left chest 3 years ago. The skin lesion has slowly increased in size without any subjective symptoms. Histopathologic examination revealed proliferation of clear cells within a sharply demarcated area of the epidermis. The presence of numerous neutrophils throughout the epidermis were also noted. (Kor J Dermatol 28(5): 642-645, 1990)
