  • The purpose of this study is to develop geological field sites for open ended education and inquiry learning, and to find the influence of field study on the affective domain in science and the achievement. As for the field sites, we used the areas ranging from Chaeseokgang- of Kyeokpo, in Buan, to around Bangsanje from Naejang-dong in Jeongeup to Ssangchi-myun in Sunchang-kun, Jeolla North Province. The affective domain in science is composed of three parts-cognition of science, interests toward science, and the scientific attitudes. to evaluate the stage of the achievement, we used questionnaire composed by 25 items. While the control group does not show any change in three parts of the affective domain, the experimental group shows positive changes, from 2.44 to 2.37 (cognition of science), from 3.15 to 3.08 (interests toward science), and from 2.91 to 2.74 (scientific attitudes) on Likert Scale. Also the score arranged by the analysis of covariate shows that the experimental group is more positive than the control group by 0.12 point in cognition of science, by 0.15 point in interests toward science, and by 0.23 point in scientific attitudes. In terms of the stage of achievement, the score of the experimental group, which is arranged by analysis of covariate, is 7.68 higher than that of the control group, on maximum of 100.

  • Seventy two species of armored scale have been recorded from the Korean peninsula since late 1920s. Nine of these species were obtained from greenhouses. Of these 9 armored scale species, 7 species are considered to have failed to colonize fields or greenhouses and 2 species, which were collected from pineapple plants, Tillandsia plants and cactus trees in greenhouses, were never taken from the exterior environment.

  • 이 논문에서는 한국항공우주연구원 위성영상 검 보정 test site 중 하나인 충남 당진 연구지역에 대하여 AMS 시스템을 이용한 항공촬영과 분광반사도 측정, GCP target 실험, GPS 측량, 토지피복조사 등 ground truth를 통하여 구축된 자료를 소개하고, 구축된 자료를 이용하여 AMS 영상의 분광특성을 분석하였다. AMS 영상 DN값과 야외 분광반사도 측정값과의 선형회귀분석결과, AMS 영상의 모든 spectral band에서 DN값과 분광반사도 측정값이 매우 밀접한 관계가 있음을 알 수 있었다. 선형회귀식을 이용하여 AMS 영상을 reflectance 영상으로 변환하였으며, reflectance 영상과 야외 분광반사도 그래프가 거의 일치하였다.

  • Ginseng damage by the African mole cricket (GTyllotalpa africana Palisot de Beauvois) was investigated in the field and laboratory from 1984 to 1991. Ginseng damage by G. africana occurred mainly in the 2nd year ginseng fields during May and June (spring period), and the damage was not nearly recognized in September and October (fall period) when densities of G. africana adults were higher in the field. In the laboratory and field cage, damage of 2nd year ginseng considerably decreased during fall period, which had no relation to ginseng diameter, and 3rd year ginseng was not damaged at all. Soil hardness seemed to influence on ginseng damage by G. africana adults.

  • Investigation of bedrock quality and the legal restriction for developing the aggregate resources were carried out with GIS in the Wondeung area Gokseong-gun, Jeollanam-do province. Firstly, we surveyed the exposed bedrocks in the field and examined in physical properties in the lab. Secondly we analyzed the legal restriction by using GIS based on bufferzone and viewshed analysis. At the results of this study, the area can be used totally as the crushed stones. However the suitability sites of crushed stone have various regulations. So the legal restriction is the principal standard to develop the crushed stone in the Wondeung area. Suitable site for crushed stones are about 30% in the Wondeung area.

  • Photo scanning can create point cloud and polygon models like 3D scanners bringing an object into the 3 dimensional world by combining several sheets of photographic information. The created data give us information about planes and sectional forms required for a 2 dimensional survey as well as 3 dimensional figures of buried cultural property. It requires a lot of time to record buried cultural property in the field, however, the photo scanning technique does not need additional equipment and manpower so the work may begin immediately while the property is protected. Moreover, it reduces financial burdens as it creates 3 dimensional data using images acquired by photography but provides the optimal condition to check 3 dimensional information quickly and easily.

  • This study was aimed to examine the Landsat Enhanced Thematic Mapper Plus (ETM+) index, which matches well with the field survey data in the wildfire area of Gangneung, Gangweon Province, Korea. In the wildfire area NDVI (Normalized Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index), and Tasseled Cap Transformation Index (Brightness, Wetness, Greenness) were compared with field survey data. NDVI and SAVI were very useful in detecting the difference between the wildfire and non-wildfire area, but not so in classify the soil types in the wildfire area. The soil plane based on the Tasseled Cap Transformation showed a better result in classifying the soil types in the wildfire areas than NDVI and SAVI, and corresponded well with field survey data. Using a linear function based on greenness and wetness in the Tasseled Cap Transformation is expected to provide a more efficient and quicker method to classify wildfire areas.

  • Even though various geological attractions are distributed domestically, the geological attractions are rarely utilized as field course site. The purpose of this study is to make Seonangbawi area as the field course site after geological investigations are carried out in detail. Seonangbawi is located about 1km southeast from Songjiho beach in Gangwon-do. Seonangbawi area is simply composed of Cretaceous Seokcho granite with the overlay of Quaternary alluvium. Geological field course in the Seonangbawi area will be useful to the student and citizen for developing the knowledge of geological phenomena, such as the formation of granite and minerals, and weathering process. In addition, the student and citizen can develop the knowledge of the geological structures, such as joint (N50E/80NW, N40W/84SW), fault (N42W/83SW), foliation (N32E/54SE), and dyke (N35E/40SE, N26W/63SW), and geographical features, such as tor, taforni, groove, and gnamma in the field. Accordingly, the Seonangbawi area is the best place to learn various geological and geographical phenomena and to discuss the origin of Seonangbawi with limited space.
