The purpose of this study is to develop a prototype curtain wall with improved seismic performance and to verify the seismic performance by conducting an inter-floor displacement test. To this end, a prototype of the curtain wall was manufactured and a displacement similar to the earthquake load was induced, and then the damaged state of the curtain wall was checked. As a result of the first test, the frame and glass of the curtain wall were not damaged, but the Weather Sealant was partially damaged. As a result of the second test, there was no problem of glass breakage in seismic class (special), seismic class (I), seismic class (II), and AAMA 501.6. Through this experiment, the seismic performance of the curtain wall prototype was verified.

Adsorption equilibrium characteristics of Ph2 Cu2+ and Cd2+ from aqueous solution using Manila clam waste shell particles were studied. The physical and chemical properties of Manila clam waste shell particles were analyzed using porosimeter, SEM, XRD and TG/DTA. The adsorption amount of Pb2+, Cu2+ and Cd2+ on Manila clam waste shell was in the following order: Cd2+ > Ph2+ > Cu2+. The adsorption equilibrium data for Pb2+, Cu2+ and Cd2+ on the adsorbents were correlated with the Langmuir and Freundlich isotherm and the Langmuir isotherm gave the best fit to our data. Also, the thermodynamical parameters were calculated with the Langmuir constant in term of temperature of Cd2+ aqueous solution.

In this study, we investigated the effects of sol preparation process variables in order to control microstructure characterization of high activated anatase type TiO2 particles. Using TTIP as a starting material, we prepared TiO2 sol solution through the process of hydrolysis/ polycondensation, aging, and peptization. As a result of this study, we found that aging among the sol preparation step had an influence upon characterization of calcined TiO2 particles as well as hydrous TiO2 sol particles. According to aging we could control the crystallinity and microstructure of TiO2 sol particles and calcined TiO2 particles. And we could also control the size distribution of average hydrous TiO2 sol particle. The microstructure of TiO2 sol particles controlled by aging had an influence on the microstructure of calcined TiO2 particles. Hence, we propose that the aging was the most important factor to control microstructure of calcined TiO2 panicles and films.

Porous activated carbons were prepared using bamboo and applied to the removal of volatile organic compounds and reactive dyes. Adsorption equilibrium and column dynamics were also investigated. It was found that the activated carbon prepared in this work can be successfully applied to the removal of pollutants from gas and liquid phases.

본 논문은 시그니처의 효용성을 평가할 수 있는 방법을 제안하고 있다. 오늘날 급속히 증가하고 있는 사이버 공격과 악성코드로 인해서 IDS가 보유해야하는 시그니처의 수도 급격히 증가하고 있다. IDS가 보유 가능한 시그니처의 수를 초과할 경우, IDS 성능 저하의 원인이 된다. 시그니처의 탐지율을 수치로 표현해서 각 시그니처의 효용성을 평가할 수 있다면, IDS는 검증된 시그니처만을 보유할 수 있고 성능저하도 막을 수 있다. 본 논문은 Snort룰을 XML 형식으로 변환한 후, 시그니처 효용성을 평가할 수 있는 속성을 추가하여 시그니처의 등급을 결정하는 방법을 제안한다.
