The author aimed to describe the volcano-stratigraphy and petrology of the volcanic mass in the Koheung peninsula, South Cheolla province. The volcanic mass is composed of the volcanics and intrusives of late Cretaceous which extruded the Pre-cambrian metamorphic(Jirisan gneiss complex) and the early Cretaceous sedimentary(Duwon Formation) basement. The volcanic pile consists of, in ascending order, Bibongsan andesite, Koheung tuff and breccia, and Palyeongsan welded tuff, and are intruded by ring intrusives( intrusive breccia, andesite porphyry, intrusive rhyolite and fine-grained quartz-diorite) and central pluton(diorite, quartz monzodiorite, biotite granite and micrographic granite). Bibongsan andesite mainly consists of andesite tuff and lava. Koheung tuff consists of alternation of fine tuff, coarse tuff and lapilli tuff, and Palyeongsan welded tuff which overlies Koheung tuff, comprises K-feldspar and quartz phenocrysts, elongated brown fiamme, lithic fragments in matrix of devitrified brown glass shards, and mainly consists of rhyodacite to rhyolite vitric ash-flow tuff. The results of petrochemical studies of the igneous rocks suggest that the rocks were a serial differentiational products of fractional crystallization of calc-alkaline magma series. This study reveals that the volcanic mass in this area is inferred to the remnant of the resurgent cauldron, measuring 30 by 25 km in diameter. The cauldron block was lowered at least 1,000 m by ring fault displacement.

The purpose of this paper is to show how the history of science can be used as a means for improving students` atmospheric pressure misconception. Students` understanding for atmospheric pressure conception and teaching-learning process for atmospheric pressure were investigated by questionnaires. It proved out that students couldn`t fully understand the concept of atmospheric pressure after learning atmospheric pressure and showed many misconceptions. To compare the effect of the teaching method guided by history of science with the traditional teaching method for atmospheric pressure conception, 99 students in two classes in the second grade middle school in Taegu City were picked out. Teaching method guided by history of science to experimental group and the traditional teaching method to normal group were applied. The tests carried out 3 times; before class, just after class, and 3 months after class. As a result of evaluation, normal group was better than experimental group before class. As a result of evaluation, normal group was better than experimental group before class. But experimental group which took the teaching method guided by history of science was better than normal group just after class. And the experimental group was better than normal group 3 months after class. From these results, it is sure that the effect of the teaching method guided by history of science was better than the traditional teaching method in the teaching-learning process of atmospheric pressure conception. Also there was the effect of improvement in atmospheric pressure misconception by putting the teaching method guided by history of science into classes.
