지질도 매핑 시스템이 국내외적으로 개발되고 있으나 아직 국내 환경에 적합한 시스템이 없기 때문에 활용되지 못하고 현재까지 현장에서 매핑될 지질 정보를 수기로 입력하고 있다. 이와 같은 고전적인 방식은 작업 데이터 공유, 데이터 유실 및 프로젝트 관리문제를 뒤따르게 된다. 따라서 이와 같은 문제를 해결하기 위하여 이 연구에서는 컴퓨터 기반의 야외지질정보 매핑 시스템을 설계하고 구현하였다. 이 시스템은 노트북과 GPS와 상호 통합된 시스템으로 기 제작된 수피지형도를 배경으로 현위치의 노두 정보가 입력 가능하다. 이를 위하여 GPS 좌표와 TM좌표간 좌표 변환모듈을 통하여 현 좌표를 실시간으로 입력 할 수 있도록 하였다. 또한 기 작성된 수치지질/지형도를 오버레이 연산이 가능하도록 하여 정밀 수치지질도 생산 및 지질도를 통한 의사결정에 활용될 수 있도록 하였다.

In Korea, the use of world geodetic system(WGS) has been mandated in year 2010. Accordingly, the national geographic information institute(NGIS) provides the digital maps according to the WGS. Nevertheless, most of the digital geological maps are still based on the Tokyo Datum(TD). Therefore, users should conduct 2D/3D geological spatial analysis after converting the coordinates of digital geological maps to WGS. The conversion process is often tedious and troublesome for certain users. Therefore, in this study, the method to transform coordinate from TD to WGS using ArcToolbox is introduced for users not familiar with the process. For a better appreciation, the Chungju and Hwanggang-ri digital sheets of 1:50,000 scale was chosen as an example. Here, Chungju and Hwanggang-ri sheets were defined based on the TD-central origin and TD-east origin, respectively. The two sheets were merged after the transformation of TD-east origin of Hwanggang-ri to the TD-central origin, and eventually transformed to WGS-central origin. The merged map was found to match exactly with the digital map(Daeso 367041). The problem of coordinate determination in previous digital geological maps was solved effectively. The proposed method is believed to be helpful to 2D/3D geological spatial analysis of various geological thematic maps.

Normally, a digital geologic map can be defined as mappable one whose spatial information with geographic information details and geologic database attribute, recorded in a digital format that is readable by computer. It shows fundamentally two different conceptual perspectives: cartography for digital mapping and analysis for geo-data processing. While, as both aspects basically relate to natural entities and their interpretation of complex features fused with multi-sources, digital geo-data mapping or geologic mapping, it should be distinguished from digital mapping in engineering such as UIS(Urban Infomation System) and AM/FM(Automated Mapping/Facilities Management). Furthermore, according to short-cycled development of GIS(Geographic Information System) software architecture based on IT(Information Technology) and wide expansion of GIS applications' fields, the importance of domain analysis and application model is emphasized at digital geologic informatizaion. In this paper, first terms and concepts of geo-data model with general data modeling aspects are addressed, and then case histories for geo-data modeling and several approaches for data modeling in GIS application fields are discussed. Lastly, tentative conceptual geo-data modeling by using UML(Unified Modeling Language) of OO(Object-oriented) concepts with respect to USGS/AASG geo-data mode is attempted. Through this approach, the main benefits for standardization and implementation lineage with conceptual model in consideration to reusability are expected. Conclusively, it is expected that geo-information system and its architecture by UML is the new coming key approach for the GIS application in geo-sciences.

Geological map and data are needed for land use planning, resources development, geological hazard prevention, environment protection and education, Since the nationwide geological database in Korea has not been constructed yet, there are many problems in using the geological map and data. There are many problems such a stratigraphy unestablishment, map conservation and edge matching in geological paper map. Therefore it is difficult to construct the geological map database, but the geological map database must be constructed as soon as possible as one of national thematic map. In this study, geological maps of pilot area such as Ansung geological map on a scale of 1:50,000, Busan on a scale of 1:250,000, Namchang on a scale of 1:25,000 and the whole Korean peninsula on a scale of 1:1,000,000 were designed and constructed to database using Geographic Information System(GIS). In addition the geological map management program was developed by GIS program. The digital geological maps were produced using the constructed geological database. The database could be of access through Internet World Wide Web(WWW) environment and be distributed in Compact Disk(CD).

물리ㆍ화학적 및 효소적 방법을 이용한 근육의 품질판정 지표로써 수분함량, 지질함량 그리고 콜라겐 함량등을 살펴보았으며, AEC 수치로써 건강도를 측정하고자 하였다. 즉, 이런 지표들을 이용하여 양식산 활어의 품질에 가장 큰 요인으로 작용하는 파괴강도와의 상관관계를 살펴보고자 하였다. 지금까지 조사된 양식산 활어성분 중 파괴강도가 어떠한 독립변수들에 의하여 크게 영향을 받으며, 파괴강도와 독립변수와의 관계식은 무엇인가를 규명하기 위하여 회귀분석을 실시하였다 여기서 독립변수로 사용된 것은 아래와 같다. X$_1$ : 수분함량(moisture content) X$_2$ : 지질함량(lipid content) X$_3$ : 콜라겐 함량(collagen content) 각 성분간의 상관관계를 피어슨 상관계수로 나타낸 것으로, 파괴강도와 수분 함량, 지질함량사이에는 상관성이 있으나(r=0.66, r=-0.69: p<0.05), 콜라겐의 함량과는 상관성을 가지지 못하였다. 또한, 콜라겐과 수분함량(r=0.19), 콜라겐과 지질함량(r=-0.29)로 각 성분간의 상관성이 존재하지 않았다. 그러므로, 파괴 강도값은 지질과 수분함량간의 상관관계가 형성된다. 즉, 수분함량이 크고 지질함량이 작아지면 파괴강도간은 커진다는 결론이다. 이 결과를 이용하여 파괴감도, 수분함량 그리고 지질함량간의 회귀분석을 실시한 결과 다음과 같다. Y = 0.74481 ＋ 0.01323 X$_1$- 0.05821 X$_2$ 이 회귀식을 이용하여, 참돔의 수분함량과 지질함량을 측정함으로써 참돔의 품질을 결정할수 있는 파괴강도값이 계산으로 얻어진다. 또한 효소적방법으로써 품질지표인 AEC수치를 측정함으로써 건강도를 판정할 수 있다. 그러므로, 파괴강도값을 이용하여 품질의 등급을 선정하며, AEC수치를 건강도의 등급을 선정하여야 된다. 파괴강도값에 의한 등급은 1.4kg이상은 상급, 1.2~l.4kg은 중급, 1.2kg이하를 하급으로 선정하며, AEC수치는 1.0~0.9는 상급, 0.9~0.8는 중급, 0.8이하를 하급으로 선정하여 등급화를 분류할 수 있을 것으로 판단된다.

Effects of Galgeun(Pueraria radix) extracts on plasma and liver lipid composition, liver function and antioxidative capacity were investigated in rat fed high oxidized fat. Plasma total cholesterol and triglyceride concentration increased in the high oxidized fat groups, however these values showed a tendency to decrease in the Galgeun extracts groups. Plasma HDL-cholesterol concentration revealed a tendency to increase in Galgeun extracts groups. The concentration of liver total cholesterol showed no significantly different in all treatment groups, however liver triglyceride concentration showed a tendency to decrease in galgeun extracts groups. Thiobarbituric acid(TBARS) concentration in plasma and liver showed a tendency to decrease in galgeun extracts groups. The galgeun extracts samples have also decreased the plasma GOT and GPT activities, whereas they have increased the liver glutathione peroxidase, superoxide dismutase and catalase activity.
