참외의 시설재배는 초기에 소형 턴넬재배로 부터 시작하여 '95년 현재 전체 재배면적 11,999㏊ 가운데 시설재배가 81.2%인 9,745㏊에 달하여 시설재배가 주류를 이루고 있다. 그러나 그 재배시설은 대부분 단동하우스내에서 소형턴넬을 이용하는 무가온 보은재배형태이기 때문에 환경관리가 부적절한 실정이다. 특히 최근 고당도 신품종보급과 함께 연중 생산ㆍ소비추세의 영향으로 (중략)

본 연구에서는 1998년 8월 12일 홍수가 발생했을때 충청북도 옥천, 보은 지역을 촬영 한 RADARSAT 위성영상을 이용하여 수계지역 추출 및 홍수지역 모니터링을 수행하였다. 이를 위해서 RADARSAT 영상에 대해 전처리를 수행하고, 전처리된 영상과 수치고도모형으로부터 생성된 경사도 자료를 이용하여 홍수발생시 수계영역을 추출하였다. 추출된 수계영역과 기존의 토지이용 현황도를 이용하여 침수지역의 현황을 분석하고, 토지이용별 침수면적을 산정하였다. 나아가 수치고도모형과 홍수시 수계를 이용하여 금강권 유역의 호우로 인해 증가된 유량을 간접적으로 산정하였다.

To investigate the unsaturated characteristics of the Boeun granite weathered soil, matric suction and volumetric water content were measured in both drying and wetting paths using Automated Soil-Water Characteristics Curve Apparatus. Based on the measured results, Soil-Water Characteristics Curve was estimated by van Genuchten (1980) model. The relationship between effective degree of saturation and matric suction showed the non-linear curve with S-shape and the hysteresis phenomenon occurred during drying and wetting paths. Suction Stress Characteristics Curve was estimated by the Lu and Likos (2006) model. The suction stress in drying path was constantly maintained and that in wetting path tended to increase when the effective degree of saturation was low. But the suction stress in drying path was larger than that in wetting path at the same degree of saturation when the effective degree of saturation became larger. Meanwhile, Hydraulic Conductivity Function was evaluated by the van Genuchten (1980) model which is one of the parameter estimation methods. The unsaturated hydraulic conductivity decreased with increasing the matric suction, and the decreasing velocity regarding to the matric suction in drying path was larger than that in wetting path.

In this study the infinite slope model, one of the physical landslide models has been suggested to evaluate the susceptibility of the landslide. However, applying the infinite slope model in regional study area can be difficult or impossible because of the difficulties in obtaining and processing of large spatial data sets. With limited site investigation data, uncertainties were inevitably involved with. Therefore, the probabilistic analysis method such as Monte Carlo simulation and the GIS based infinite slope stability model have been used to evaluate the probability of failure. The proposed approach has been applied to practical example. The study area in Boeun area been selected since the area has been experienced tremendous amount of landslide occurrence. The geometric characteristics of the slope and the mechanical properties of soils like to friction angle and cohesion were obtained. In addition, coefficient of variation (COV) values in the uncertain parameters were varied from 10% to 30% in order to evaluate the effect of the uncertainty. The analysis results showed that the probabilistic analysis method can reduce the effect of uncertainty involved in input parameters.

A lot of waterlogged shrouds and mummies have been found in tombs revered with lime of the Chosun Dynasty(1392-1910) of Korea. Shrouds were heavily polluted with greyish white material. Greyish white material, which adhered to shrouds excavated from tombs(16C and 17C), was submitted to FT-IR qualitative analysis and fatty acid analysis for cleaning. The results of the FT-IR qualitative analysis identified the main ingredient of the greyish white material as calcium salt of fatty acid, including a little of the fatty acids, lipids and proteins. Therefore the greyish white material fumed out adipocere which was formed from the degradation of the lipids in a dead body. From the fatty acid analysis, hydroxy fatty acids(10-Hydroxyhexadecanoic acid and 10-Hydroxyoctadecanoic acid), which were found in adipocere, were detected. The distribution of contents of fatty acids was also rimilar to that of adipocere which have a high proportion of palmitic acid of saturated fatty acid and a low proportion of oleic arid of unsaturated fatty acid. In view of the results of analyses, it was revealed that greyish white material adhered to shrouds was adipocere moved from a mummy.

The natural treasure is not only a product of nature and but also a heritage we need to protect. Among natural treasures, because an animal and a plant have lives, one of them are sure to be disappeared. The natural treasure, Sok-ri mountain's Jungyeepoomsong is unique. It is the only alive tree which secure a government position. Currently the Jungyeepoomsong gets into difficulty because of natural disasters and insect attacks. In addition, it is in a critical condition of dying old since the age of the tree is over 600 years. The purpose of this paper is to investigate plans for tourism resources of the Jungyeepoomsong. Because the Jungyeepoomsong is a rare variety, it can be commercialized as a plant resource. Also, it can be used as the method of creating income for local residents. To achieve research objective, this paper proposes the plans of a lineage certification using a genetic analysis technology, a genealogical table control system utilizing purebred preservation and storytelling, a database construction between producers, sellers, and owners, a tourism event, a method of building Jungyeepoomsong's brand and preserving its value.

This Study analyzed heavy snow properties according to the area that was based by winter weather properties and the damage data by the heavy snow among each local government of Chungcheongbuk-do. The result of analysis, Jecheon-si and Boeun-gun are represented the highest dangerous regions by potential degree of risk by average amount of snowfall for 35 years. But, the potential degree of risk by maximum amount of snowfall for 35 years is different with it. Cheongju-si and Youngdong-gun, Goesan-gun, Boeun-gun are represented the highest dangerous regions. Examining the frequency of regions with potential danger factors according to the characteristics of heavy snowfall, Boeun-gun and Jecheon-si, Goesan-gun, Youngdong-gun, Cheongju-si is derived the highest dangerous regions in Chungcheongbuk-do.
