  • Staurolite grains in staurolite, kyanite and sillimanite zones occurred in the Littleton Formation, Northcentral Massachusetts have interpreted to form by Barrovian-type metamorphism during Acadian orogeny. However, various occurrence of staurolite in the three zones, (a) porphyroblast, (b) randomly oriented and coarse-grained muscovite pseudomorph after staurolite, (c) recrystallized staurolite at the margin of garnet porphyroblast and within the pseudomorph, indicates that they have resulted from polymetamorphism. Staurolite in these three metamorphic zones can be formed by demise of chlorite or chloritoid that depends on difference of bulk-rock compositions and changes of P-T conditions. Staurolite modal proportion calculated in MnNCKFHASH system using THERMOCALC program reveals that staurolite could have grown with garnet with increasing pressure and temperature, if it coexist with chlorite. After demise of chlorite and appearance of biotite, staurolite mode decrease with increasing pressure and temperature. Therefore, based on the previous P-T paths for the Acadian metamorhism, staurolite porphyroblast grew with garnet during 400-370 Ma. Randomly oriented and coarse-grained muscovite pseudomorphs after staurolite probably have grown due to heating with appearance of kyanite and sillimanite. Consequently, pseudomorphisrn of staurolite occurred by heating derived from locally intense Alleghanian shearing (ca. 320-300 Ma) overprinted the Acadian metamorphism. Recrystallized fine-grained staurolite in sillimanite zone observed between the grain boundaries of muscovite in the pseudomorphs and at the edge of garnet porphyrobasts has formed during decreasing temperature and pressure (ca. 300-280 Ma) after peak temperature (ca. $700^{\circ}C$) of the Allegllanian metamorphism.

  • This Study is concerned with the architectural problems particular to the design of the sanctuary in Catholic churches. The paper is meant to address two distinct groups - clerics and architects. Architects do not tend to think the church buildings theologically or liturgically, and priests, though they are often trained in the arts, do not tend to look at buildings the same way architects do. Hence, my goal is to adequately address the concerns of each in a language the other will understand, thereby building a bridge of communication between the two groups. The two main concerns of the study are to provide guidelines and reflection lot liturgically correct buildings, and to re-establish the traditions of church buildings. I discuss the idea of the sanctuary in the Catholic church,(in chapter 2) and examine each of the main furnishings of the sanctuary with regard to history, liturgical use, symbolism and related pastoral concerns.(in chapter 3,4).

Regional-scale metasomatism of Al, K, and Na during stauroliteandalusite- grade contact metamorphism, in the southwestern Nova Scotia, Canada (십자석-홍주석 접촉 변성과정에 수반된 Al, K, Na의 광역적 변성교대작용 - 캐나다 노바스코시아주 서남부의 예 -)

  • Pelitic rocks of southwestern Nova Scotia have been affected by widespread contact metamorphism due to the intrusion of the Shellburne Pluton, with aureole up to 15 km wide. Well-preserved pseudomorphic textures indicate that common staurolite and andalusite metacrysts formed at the expense only of plagioclase, muscovite and biotite. Excess components (K, Na and Ca) from such replacement reactions imply extensive metasomatism throughout the contact aureole. Modal analysis of a typical andalusite-bearing rock indicates a one-to-one volume ratio of product to reactant. However the products of the replacement reactions contain approximately three times more aluminum than the reactants, indicating that the regional metasomatism also involved aluminum.

  • This researcher has sorted out the development process of death aesthetics contained in human art through advanced research. This research is a follow-up study of related research, which studies the aesthetic meaning of death in Alexander McQueen's fashion works. This study first classifies the aesthetic characteristics of death, and then analyzes and sorts out the aesthetics of death in Alexander McQueen's clothing works based on this. The results of this study are as follows: first, the aesthetic manifestations of death are divided into three categories: reproducibility, symbolic and religious. Among them, the representation of reproducibility includes the representation of real objects and the representation of virtual objects, and the symbolic performance includes two types of external performance and internal performance. Second, in Alexander McQueen's works, the reproducibility of death was mainly reflected by virtual stage scenes and costumes. Thirdly, the symbolic death is not only reflected in the skeletons and blood etc. directly related to the death of the body, but also in the various emotions and psychological states caused by the death. Fourth, the religious nature of death was represented in Alexander McQueen's works through such representative things as crosses and religious stories.
