XML 스키마의 수가 급증함에 따라 동일한 도메인에 속하는 유사한 스키마를 통합하는 방법에 대한 관심이 증가하고 있다. 일반적으로 XML 스키마 통합 과정은 스키마 클러스터링과 통합 스키마 추출의 두 단계로 구성된다. 본 논문에서는 통합 스키마의 추출을 위한 효율적인 방법을 제안한다. 제안된 방법은 공통 구조 추출, 스키마 통합, 그리고 최적화의 세 단계로 이루어진다. 실험결과, 제안된 방법은 처리시간 및 정확도 측면에서 우수란 결과를 보였다.

The surface of Poly(ether imide) (PEI) membranes has been sulfonated using CIS03H. The resulting membranes were characterized through the analysis of ESCA and contact angle measurements The sulfonated PEI membranes were exposed to gases of $O_2$, $N_2$, and $CO_2$ to measure the permeation rates and ideal separation factors. In addition, the diffusivities and solubilities of individual gases were measured. The diffusivity effect is more dominant than the solubility one on gas transports.

As abnormal climate phenomena occur more frequently due to climate change, damage which results from meteorological disaster increases accordingly and its scale and variety are becoming wider. This paper draws out planning and design elements and application techniques to build cities more adaptive to climate change from urban development cases in US and Europe. An urban model is suggested, that enables built environment to be more resilient to risks caused by climate change is applicable to urban development projects in practice.

The goal of current study is to make a standard pattern identification for post stroke depression using a delphi method. Finally, ten experts of oriental medicine, especially of stroke or depression, participated in Dephi examination. At the first meeting, experts conducted free discussion and determined to use the previous published questionnaires of Deficiency-Excess identification and Cold-Heat identification. From the second round, experts participated in evaluating and correcting the questionnaire by email. New seven questions were added to the questionnaire of Deficiency-Excess identification through the second round. Finally, the standard pattern identification of Cold-Heat or Deficiency-Excess is composed 20 questions and 11 questions, respectively. These pattern identifications for post stroke depression will contribute to research and treatment of oriental medicine.

LTCC (Low Temperature Co-fired Ceramic) has been emerged as a promising technology in packaging industry. In this technology the lamination and the sintering process are very important because they change the permittivity of ceramics and the dimension of metal pattern which have influences on electric property. In this paper we studied on influence of the permittivity and the dimension change by lamination pressure and sintering temperature of LTCC process. As a results, permittivity increase along with increasing of lamination pressure and sintering temperature.
