The expression KES, one of the most commonly used words in the Korean language, has various usages. This expression is also used to express English-like cleft constructions. Korean seems to employ at least three different types of cleft constructions: predicational, identificational, and eventual. The paper tries to provide a constraint-based analysis of these three types of Korean cleft constructions and implement the analysis in the LKB(Linguistic Knowledge Building) system to check the feasibility of the analysis. In particular, the paper shows how a typed feature structure grammar, couched upon HPSG, can provide a robust basis for parsing Korean cleft constructions.

본 논문은 변형된 한국어 문장에 대해 변형 이전의 문장과의 의미적 동일성을 분석하여 한국어 의문문 질의어의 문형과 상이한 문형의 한국어 문장도 정보검색시 검색 대상문에 포함시켜 검색 정확도를 높임으로써 의문문 질의 시스템의 성능을 향상시키는 것에 연구의 초점을 맞추고 있다. 한국어 문장에서 주로 나타나는 피동화에 의한 변형, 분열문에 의한 변형, 명사화에 의한 변형, 어순 재배치에 의한 변형 등의 특성에 대해 알아보고 의문문 질의 시스템에서 그들 각각의 변형을 인식하여 변형 이전의 문장과 동일한 의미의 문장으로 처리하는 방법에 대해서 자세히 살펴보았다.

인간과 같은 척삭동물문에 속하는 우렁쉥이 (Halocynthia roretzi)의 유생은 척추동물의 체제를 매우 단순화시킨 구조를 하고 있다 (Nishida, 1997). 유생은 약 10여종의 세포들로 구성되며, 미부 중앙에 척삭과 그 위에 신경관의 원형 (prototype)을 갖는다. 모든 배(embryo)들은 초기 발생과정에서 언제나 동일한 세포분열과 발생운명 양식을 나타낸다. 또한, 해부현미경을 이용하여 수정란으로부터 초기 원장배에 이르기까지 원하는 하나의 할구만을 분리, 제거 및 재결합하는 등의 micromanipulation실험이 가능하다.

Inversion at variable time of the uncleaved eggs of Rana nigromaculata and Rana dybowskii was emplyed to study the mechanisms of early embryogenesis. The response to inversion varied between those two spcies. If the eggs were inverted at early time it was possible to change the site of the first cleavage furrow of Rana nigromaculata-it appeared on the original vegetal hemisphere (OpG side). However, the first cleavage furrow of Rana dybowskii was not changed at all no matter what its inversin time was-it always appeared on the original animal hemisphere (G. side). In the inverted Rana nigromaculata embryos the size of the blastomeres on the vegetal hemisphere was always smaller than those of animal hemisphere. On the ocntrary, the cleavage pattern of Rana dybowskii was not altered. Results of the histological works for the inverted eggs suggest that the different responses to inversion might be caused by the fact that the extent to which the redistribution of the egg components such as cleavage nuclei and yolk platelets are different.

Kiho Academic in the late Joseon Korea, the negative effect of the Horak debate is amplified and the division within the academic is accelerated. However, the scholars of the Kiho Academic field put forth efforts to unify the academics with the same sense of responsibility to end the schism. Nevertheless, the scholars of the Kiho Academic have shown various differences in the process of accepting Neo-Confucianism, which creates new schools. Therefore, Kiho Academic in the late Joseon Korea coexisted with various schools with different academy positions. Some of the representative groups are Hwaseo, Nosa, Ganjae, Yeonjae, and Uuidang Schools. In addition, through the scholarly differentiation and the school division of the Kiho Academic, the debate on the mind that characterizes Neo-Confucianism of the late Joseon Korea has developed. However, there was a common value that everyone pursued in the middle of the debate: the construction of a moral ideal society, the ultimate goal of Neo-Confucianism. In conclusion, though the purpose they pursued was not fulfilled, it can be seen from the debate on the mind that they fiercely demanded that these requests were urgent in the late Joseon Korea This paper, therefore, the situation of the Kiho academic in the late of Joseon Korea, the problem consciousness of the scholars of the Kiho academic, and the issue and development of debate on the mind.

Acidic metavolcanic rocks distributed around the Chungju iron deposit show significantly high abundances of rare earth elements and high field strength elements. Relatively high ${\epsilon}_{Nd}$(0) values and lack of negative Nb anomaly suggest that assimilation of crustal material is not involved in their generation. They are plotted within the within-plate environment according the tectonic discrimination diagrams. Such geochemical characteristics are very similar to the acidic metavolcanic rocks of Munjuri Formation. They also show geochemical characteristics of Al-type magma of Eby (1992). All such diagnostic characters indicate differentiation of mantle-derived magma produced from the rift environment, related to the breakup of continent. In contrast to the alkali granites and the rare metal deposit both having age of c. 330 Ma, Sm-Nd isotopic data of the acidic metavolcanic rocks do not form well defined isochron. However, the alkali granites reveal low ${\epsilon}_{Nd}$(0) values, while the acidic metavolcanic rocks and the rare metal deposit both have significantly higher ${\epsilon}_{Nd}$(0) values. Considering such differences, we propose following generation hypothesis: The acidic metavolcanic rocks around Chungju iron deposit was erupted at 750 Ma as rest of the acidic metavolcanic rocks of Gyemyeongsan and Munjuri Formations. About 330 Ma ago, partial melting of existing Al-type igneous materials and some old crustal materials produced alkali granite. The rare metal deposit was also produced by redistribution of related materials within the acidic volcanics due to hydrothermal activities occurred at the same time. Sm-Nd isotopic systematics of the acidic metavolcanic rocks were disturbed during the regional metamorphic event at ca. 280 Ma.
