비당뇨인에게서도 이상지질형증이 발견될 경우 적합한 치료가 시행되어야 하겠지만, 당뇨병 환자의 경우에는 비당뇨인에 비해 심혈관계 질환을 일으킬 가능성이 2~4배에 이르고, 심혈관계 질환이 발생한 후에도 사망률이 비당뇨인에 비해 높음을 감안하면, 당뇨병 환자에서 심혈관계 질환의 강력한 위험인자인 이상지질혈증의 적절한 치료는 매우 중요하다고 하겠다. 당뇨병 환자의 이상지질혈증의 적절한 치료를 위해서는 지질대사 이상에 대한 지식이 필요하다. 본 란에서는 정상 지질대사와 당뇨병환자에서 이상지질혈증의 발생기전과 특징은 어떠하며 당뇨병 환자에서 잘 나타나는 이상지질혈증의 특성이 심혈관계에 미치는 영향이 비당뇨인에 비해서 왜 더 크며, 더 적극적인 치료가 필요한가에 대한 정보를 제공하고자 한다.

The most of groundwater with high U-concentration occur in the Jurassic granite of Gyeonggi massif and Ogcheon belt, and some of them occur in the Cretaceous granite of Ogcheon belt. On the contrary, they do not occur in the Jurassic granite of Yeongnam massif and the Cretaceou granite of Gyeongsang basin. The Jurassic and Cretacous granite, the host rock of high U-groundwater, were resulted from parental magma with high ratio of crustal material and highly differentiated product of fractional crystalization. These petrogenetic characteristics explain the geological evidence for preferential distribution of uraniferous groundwater in each host rock. It were reported recently that high U-content, low Th/U ratio and soluble mineral occurrence of uraninite in the two-mica granite of Daejeon area which have characteristics of S-type peraluminous and highly differntiated product. It is the mineralogical-geochemical evidences supporting the fact that the two-mica granite is the effective source of uranium in groundwater. The biotite granite and two-mica granite of Jurassic age were reported as biotite granite in many geological map even though two-mica granite occur locally. This fact suggest that the influence of two-mica granite can not be ignored in uraniferous groundwater hosted by biotite granite.

본 논문에서는 부분파수적분법과 유전자알고리즘기법의 조합을 통한 광대역 신호로 부터 직접적인 해저지질특성치의 역산기법을 제시하였다. 광대역주파수신호의 시간영역 모 의는 부분파수적분법을 사용하여 계산시간을 단축하였고, 다수의 국부최소점이 존재하는 역 산문제에 유전자알고리즘기법을 적용한 전역되적점에 대한 탐색을 수행하였다. 본 방법을 사용하여 해저퇴적층의 지질특성 요소에 대한 역산을 수행하였다.

Geotechnical risk factors encountered in intermediate-depth underground tunnel construction are diverse, and the types and standards of risk factors are different according to the depth and regional geological characteristics of Korea. In order to understand the effects of geological characteristics and geologic structure on safety, which show various porous characteristics of urban underground complex ground, the risk factors of intermediate-depth rock mass in Korea were analyzed based on domestic and foreign cases. As a result of the study, seven categories affecting the stability of the intermediate-depth tunneling, namely, geologic structure, rock characteristics, hydrogeology, overburden, high stress, ground characteristics and artificial structures, and about 22 risk factors were derived. We present the risk criteria and interval values for risk evaluation of faults, folds, dikes, and rocks that have the greatest influence among risk factors. Criteria and interval values for other risk factors are under study.
