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.

The purpose of this study was to analyze science gifted students` creativity subscales. The Torrance Tests of Creativity Thinking(TTCT) were administered to 385 science gifted students from 2006 to 2010 for this study. The results were as follows: First, fluency correlated highly with originality, and elaboration also highly correlated with abstractness of titles. All of the correlation coefficients of the variables with resistance to premature closure were high. Second, the elaboration scores were higher than other variables, and abstractness of titles scores and resistance to premature closure scores were lower than other variables regardless of regions and gender. There was no significant difference according to regions, but the elaboration scores of female science gifted students were significantly higher than male science gifted students. The fluency scores were the most influential factor to the creativity index among the creativity subscale scores. Third, after completing the science gifted program, students showed significant difference in fluency scores, abstractness of titles scores, and resistance to premature closure scores; however, they showed no difference in originality scores and elaboration scores.

This is the consecutive study of mineralogy of hydrothermal deposits in the Miryang ming Kyeongsangnan-do, Korea(Chung et al., 1994).This study is carried out to examin the genesis and hydrothermal alteration of the Miryang pyrophyllite deposits. This area consists mainly of the late Cretaceous volcanic rocks which is hydrothermally altered extensively and cut by several faults of post-alteratiion. The area os originally composed of acidic welded tuff. The altered rocks around the pyrophyllite deposits can be classified into the following altered zones;corundum-andalusite-pyrophyllite zone, silcified zone, pyrophyllie-sericite-diaspore zong, pyrophyllite-kaokinite-siricite zone, weakly argillized zone and weakly altered zong in the order from the center to the margin. Such zonal arrangement of altered rocks suggests that the contry rocks, most of which are acid pumiceous welded-tuffs, were altered by strongly acid hydrothermal solution.

Miryang clay deposits located in Miryang-gun, Kyeongsangnam-do, Korea, belong to the ka-olin-pyrophyllite deposits related to the late Creataceous volcanic rocks. The mode of occur-rence of the kaolin-pyrophyllite deposits and the genetic relation to the volcanism were studied in the Miryang area. This area is underlained by rhyolitic welded tuff in the ascending order which are strongly altered. The rhyolite is intruding to various tuff beds which are distributed in the southeastern part of kaolin-pyrophyllite deposits. The altered rocks in the rhyolitic welded tuff can he classified into the following zones; silicified zone, pyrophyllite zone, weakly argillite zone and weakly altered zone in the order from ore shoots. The clay deposits occur as irregular massive and layer types 5 -30m in width and is accompanied by thin diaspore bed and is at outer of ore shoot Pyrophyllite ores consist mainly pyrophyllite, kaolinite, muscovite, quartz with acessory minerals, like diaspore, alunite, dumortierite, chlorite, muscovite, sericite, pyrite and mixed layer minerals. The process of kaolinization-pyrophyllitization has a close relation to a local acidic solution by acidic grantic rocks. Acid hydrothermal alteration mainly in the rhyo-litic welded tuff. It is reasonably considered that initial gas and solution containing H2S and oth-ers were oxidized near the surface and formed hydrothermal sulfuric acid solution.

The geology and mineralization of Gyeongsan mine and its vicinity were studied mainly f-rom petrochemical and geochemical point of view. The mineral composition of ores and the content varations of trace elements in carbonate veins wers investigated in relation to the origin of ore deposits. From field observation, microscopic study and chemical analysis of major and trace elem-ents it may be summarized and concluded as followings: 1) Mineralization is assumed to have been formed from carbonate-rich hydrothermal so-lution passing through the fissures developed in the granitic rocks. The major strike and dip of the fissures are NS to N10°E and nearly vertical. 2) The characyeristic variation trends of several oxides of bulk chemical analysis and modal analysis of the granitic rocks indicate that the rocks belong to adamellite to granite and have some similarity to the granite of G group in southern Gyeongsang basin and the younger granite of Ogcheon geosynclial zone. Ore minerals in the carbonate vein are mainly arsenopyrite, molybdenite, pyrite and sphalerite. Sphalerite associates occasionaly with small amounts of bismuthinite and chal-copyr te. Gangue minerals found in this ore deposits compsed of calcite, dolomite, anker-ite, quartz, K-feldspar etc. 4) The distribution pattern of trace elements show that Co content is mostly low and tends to decrease, like Cu and As, With depth, and that Mo content is high in drill holes of No. 5 to 7 and rends to increase with depth. It seems that the variation trends of Co fairly show similarity with As and Cu, but dissmilarity with Mo and the others. 5) The raw ores of the past might be cobalt-bearing arsenopyrite, that was much enri-ched in Co, considering the ratio of Fe/Co based on the past analytical results of arsen-opyrite.

Clay minerals are locally abundant in two hydrothermal areas at Tongnae-Yangsan and Miryang, Gyong-sang-namdo, Korea. This study is done to access the clay forming processes, particularly hydrothermal alteration. Pyrophyllite-kaolin in the Zone is accompanied by sericite, diaspore mixed-layer mica/smectite, alunite, dumortierite and silica minerals. Small nodular diaspore and disseminated fine radiac dumortierite are present in the pyrophyllite-kaoline deposits, the northemly trending belt of rhyolite flows and pyroclastic rock near the intruded by granite rock of Bulkusa Series. Hydrothermal action has formed many clay deposits with a zone containing over 80~90% pyrophyllite, kaolinite, muscovite with a little amount of dumortierite, boehmite, andalusite. Most of the clay deposits occur as irregular, lenticular, massive and assosiated dumortierite was found to coexist with clay deposits. Dumortierite data are as follows: lattice constant a=11.783, b=20.209, c=4,7001, axial ratio a:b:c=0.5835 : 1 : 0.2327, XRD $d{\AA}$ 2.549, 5.89, 5.09.
