초록

경상분지의 후기 백악기~고 제 3기의 화산암류는 high-K 칼크 알칼리의 특성을 나타내며, 클라-태평양의 섭입에 연관된 마그마작용에 성인적으로 연관된다. 그들은 삽입에 관련된 마그마에서 보이는 바와 같이 고장력원소가 결핍되며 LIL원소가 부화되는 특성을 지닌다. K-h 관계에 기초하여 마그마의 생성 깊이를 180~230km라고 한 이전의 연구들은 재고되어질 필요가 있다. 물을 0.4%함유한 감\ulcorner암의 부분 용융의 깊이는 80~120km로 알려져 있으며, 성숙되기 전의 호에서 섭입 슬램은 70km보다 얕은 깊이에서도 용융이 될 수 있다. 더욱 더 $K_2O$ 함량은 지각물질에 의한 혼염과 섭입 슬램의 유체에 의해서, 그리고 적은 정도의 부분 용융에 의해서도 증가될 수 있다. 섭입의 각도를 $30^{\circ}$로 자정하였을 때 수직깊이 180~23km는 수평거리가 해구로부터 310~400km로 계산된다. 이 깊이는 도호 및 대륙호에 속한 다른 지역의 근원마그마 생성심도에 비해 매우 큰값이며 섭입에 의해 야기되는 환산암의 생성지의 분포하는 조와적이지 못한다. 경상분지 화산암의 $K_{55}$는 0.3~2.3wt.%이며, 그 평균값을 Marsh and Carmichael (1974)의 도표에 적응하면 섭입대의 깊이는 80~170km가 된다. 깊이 180~230km의 맨틀 암석은 석류석 러졸라이트로 자정되며 이것의 분별로부터 나타나는 회토류 양상은 경상분지의 것과 일치하지 않는다. 더욱 더 섭입에 관련된 마그마작용을 연구한 여러 연구자들은 이보다 더 얕은 깊이를 제안하였다. CaO와 $Na_2O$ 함량을 이용하여 구한 후기 백악기~고 제 3기의 경상분지의 고지각 두께는 각각30km이며, La/Sm대 La/Yb 에 의한 값은 약 30km로 추정되며, 이들은 이전의 연구들을 지지한다. 뇌 활성화 영역에서 자화율 변화에 따른최대 선호 강도변화는 1.5T에서는 TE, 66ms에서 3.36%. 3.0T에서는 TE. 46ms에서 10.05%로 3.0T가 1.5T에 비해 약 3배 정도 변화가 큰 것을 알 수 있었다. 산출된 최적의 TE 값은 각각의 TE 값에서 얻은 활성화 상태와 휴식상태의 차이값의 최대의 TE 값와 일치하였다. 결론 : 뇌 기능영상에서 3.0T MRl는 1.5T에 비해 deoxyhemoglobin에 의한 자화율의 변화를 약 3배정도 잘 반영하므로 뇌 기능영상 측정시 보다 유용성이 있는 것으로 사료된다. 에코 MR 영상과 더불어 DESS 영상이 슬관절 연골연화즈의 진단에 보다 더 도움을 줄 것으로 생각한다.의 동기는 ‘일반 대중매체의 영향’이 가장 많았으며 건강소식지가 동기인 경우도 20.4%였다. 사업군에서 건강소식지가 유방암 자가검진법 실천에 영향을 미친 경우가 79.6%였으며 유방암 자가검진법에 관한 보건교육을 받고 실천하지 않은 사람들 중 미래의 실천의지에 건강소식지가 영향을 미친 경우는 43.6%였다. 이상의 소견에서 지역주민을 대상으로 인쇄매체를 통한 보건교육은 인쇄물만으로도 쉽게 실천 할 수 있는 유방암 자가검진법이 가장 효과적이었으며, 자궁암검진에 관해서도 검진을 받을 수 있도록 지역사회의 보건의료의 하부구조를 정비하여 제도적 장치를 마련하고 정보를 제공한다면 자궁암검진 실천율도 증가할 것이다.고 12.9% 의 발달율을 보여 유의적인 차이를 보이지 않았다. 이상의 결과로 보아 핵이식 수정란을 효율적으로 생산하기 위하여 수핵난자의 세포질에 ionomycin 과 DMAP 의 혼합처리로 탈핵난자의 활성화를 유도하는 것이 효율을 증진시킬 수 있었다고 본다. 또한 공핵수정란을 수정 후 90시간과 114시간 개별 배양하여 할구를 공핵체로 핵이식에 이용하였을 때도 그룹배양에 비하여 효율이 떨어지지 않음을 알 수 있었으며, 수정란의 할구 크기의 차이가

Late Cretaceous to early Tertiary volcanic rocks in the Kyongsang basin exhibit high-K calc-alkaline characteristics, and originated from the magmatism related genetically to subduction of Kula-Pacific plate. They represent HFSE depletion and LlLE enrichment characteristics as shown by magmas related to subduction. Early studies on the depth of magma generation has been estimated as 180-230 km based on K-h relation should be reevaluated, because the depth of peridotite partial melting with 0.4 wt. % water is 80-120 km at subduction zone, and subducting slab in premature arc can melted even lower than 70 km. Moreover the increase of potassium contents depends on either contamination of crustal material and fluids of subducting slab or low degree of partial melting. If the inclination of subduction zone is 30 degrees and the depth to the Benioff zone is 180-230 km, the calculated distance between the volcanic zone and trench axis would be 310-400 km. It is unlikely because the distance between the Kyongsang basin and trench during late Cretaceous to early Tertiary is closer than this value and not comparable with generally-accepted models in subduction zone magmatism. $K_{55}$ of the volcanics in the Kyongsang basin is 0.3-2.3 wt.% and the average indicate that the depth ranges between 80-170 km on the diagram of Marsh, Carmichael (1974). Fractionation from garnet lherzolite, assumed the depth of 180-230km, is not consistent with the REE patterns of the volcanoes in the Kyongsang basin. Futhermore, the range of depth suggested by many workers, who studied magmatism related to subduction, imply shallower than this depth. Crustal thickness calculated by the content of CaO and $Na_2O$ is about 30 km and about 35 km, respectively. Paleo-crustal thickness during late Cretaceous to early Tertiary times in the Kyongsang basin inferred about 30 km calculated by La/Sm versus LaJYb data, which is also supported by many previous studies.
