In order to develope and apply high-performance steel fiber reinforced concrete (SFRC), the effects of steel fibers on durability and long-term deformation of SFRC due to various mixing conditions have been studied. As the test result show, the manufacturing process technology of industrial SFRC is developed And the durability of SFRC such as freeze-thaw, resisteance abrasion resistance are significantly improved, the drying shrinkage of SFRC, is remarkably decreased by increasing the steel fiber contents than plain concrete

The objective of this study is structural analysis of continuous casting mold. A two-dimensional finite element model was developed to compute the temperature distribution, thermal stress and thermal strain behavior for continuous casting mold. Structural analysis was made using thermal analysis result, utilizing transient analysis of ANSYS. This structural analysis results, many variables such as casting speed, cooling condition film coefficient, convection and load condition are considered.

Buckling behavior of stiffened laminated composite cylindrical panel was studied using linear and nonlinear deformation theory. Various buckling load factors are obtained for stiffened laminated composite cylindrical panels with rectangular type longitudinal stiffeners and various longitudinal length to radius ratio, which made from Carbon/Epoxy USN150 prepreg and are simply-supported on four edges under uniaxial compression. Buckling behavior design analyses are carried out by the nonlinear search optimizer, ADS.

After an important construction work in Chosun dynasty, the appropriate government made out the building specification as it called 營建儀軌. They are recorded about variety matters as the appointed days, various official documents, managers and craftsmen, etc.. Sometimes we can see the attached pictures about some building or furniture. specifications in Chosun dynasty about the unit of materials and history of each terms. The results are as followings: (1) The interior materials are classified to several units such as Gai(箇;the unit of square lumber or log), Rip(立;the unit of plates), Boo(部;the unit of assembled materials), etc.. (2) The terms are defined and enlightened how to use and how to change. Particularly, the terms are different positively in constituent units of wooden floor. So, it is expected to continuant study.

During the years of KwangHaeGun, an active public services of building large scale palaces such as reconstruction of ChangDukGung and ChangKyungGung and new construction of InKyungGung and KyungFukGung were carried out. And palaces of Chosun dynasty didn't go much different from those of KwangHaeGun years. By analyzing historical records, ancient maps, palace drawings, architectural forms of ChimJun(寢殿) in InKyungGung(仁慶宮) are examined. ChimJun is sleeping rooms of king and queen. The results are followings: Since Sejong dynasty, functions of king and queen were starting to differentiate, that during the years of KwangHaeGun, two Chimjun(寢殿) were made. ChungWaJun(靑瓦殿) is king's sleeping rooms, located in the west among two, and have a blue tiled roof. KyungSooJun(慶壽澱) is queen's sleeping rooms, located in the east among two. King's ChimJun built on stone pillars, and queen's ChimJun on a wide base as it called Waldae(月臺).
