The objective of this research is to evaluate the seismic performance of steel intermediate moment frames(IMFs) with different heights. The seimic performance is conducted according to ATC-63. Three-, six, nine- and twelve-story IMFs are designed according to KBC 2009. The connection is modeled to have a drift capacity of 0.02rad, which is required for IMF connections. This study shows that the probability of collapse increases with an increase in the height of the frame. Nine- and twelve-story frames did not satisfy the requirement specified in ATC-63.

In terms of the fact that Innovation School is the main agent which encourages the innovation of school culture, As it has been ten years since the Innovation School was enforced, we do need a practical, indepth study on the quality of policy management. To make this actualize, this study is for analysis and comparison of basic values and operating evaluation plans which have been managed by Metropolitan City Office of Education(MCOE) & Provincial Office of Education(POE). Each of MCOE & POE have their own vision. Those visions are such things; 'Education for All' for Gangwon, Busan, Chungbuk. 'Future School Orientation' for Gyeonggi, Gyeongnam. 'Educational Community Realization' for Gwangju, Seoul, Ulsan, Jeonbuk, Jeju. 'Normalization of Public Education' for Sejong, Incheon, Chungnam. Like such things, each office possesses different vision by their distinct characteristics and in principle, all emphasis on publicness, democracy, and creativity. Management evaluations of the Innovation School is operated by Self-assessment, Intermediate evaluation, and Extensive assessment. The process and evaluation index of Intermediate evaluation and Extensive assessment are similar. Especially, Those assessment have significance in a role of administrating its management of each school and a role of offering associated documents of educational policy with educational renovations with feedback and some good examples.

FCM 기반 RBF 네트워크는 서로 다른 학습 구조가 결합된 혼합형 모델로서, 입력층과 중간층의 학습 구조는 FCM 알고리즘을 적용하고, 중간층과 출력층 사이의 학습 구조는 Max_Min 신경망을 적용한다. 입력층과 중간층의 학습시 입력벡터와 중간층의 노드중에서 중심과 입력벡터간의 가장 가까운 노드를 승자 노드로 선택하여 출력층으로 전달한다. 그리고 중간층과 출력층 사이의 학습 구조는 Max_Min 신경망을 적용하여 중간층의 승자 뉴런이 출력층의 입력벡터로 적용한다. 하지만 많은 패턴이 입력벡터로 제시될 경우 학습 성능이 저하되는 단점이 있다. 따라서 본 논문에서는 중간층과 출력층의 학습 구조인 Max_Min 알고리즘의 학습 성능을 개선시키기 위해 퍼지 제어시스템을 이용하여 학습률을 동적으로 조정하는 퍼지 제어 기법을 이용한 FCM 기반 RBF 네트워크를 제안한다. 제안된 방법의 학습 성능을 평가하기 위하여 컨테이너 영상에서 추출한 숫자, 영문 식별자를 학습 데이터로 적용한 결과, 기존의 ART2 기반 RBF 네트워크보다 학습 시간이 적게 소요되고, 학습의 수렴성이 개선된 것을 확인하였다.

Local governments within the boundaries of a state need increasing flexibility to satisfy diverse economic, social, and environmental goals in their particular geographical setting. However, many candidates in the local election in South Korea tend to see local politics as an extension of national-level politics. In particular, this paper mainly deals with how the voters' evaluation of a president's performance has influenced subnational elections in South Korea. Our analysis suggests that the fate of candidates in subnational elections is shaped by the performance of the incumbent president in both economic development and foreign affairs.

In this study, the intermediate layer in Pd-based hydrogen separation membrane was synthesized to minimize the surface roughness and defects using powder-type and sol-type metal oxides. The surface properties and gas permeation characteristics were analysed by SEM and $N_2$ gas permeation test. The coating layer composed of sol type metal oxides has smooth surface, especially the layer coated by $TiO_2$ sol has little pin holes, cracks and defects. The binary layer composed of powder type and sol type metal oxides has similar flux characteristics to a single sol type layer. The Pd-based composite membrane improved by the binary intermediate layer exhibited $0.32mol/m^2s$ of the hydrogen permeation flux with a selectivity ($H_2/N_2$) of ~10,890 at 672 K and a pressure difference of 1 bar.

RBF 네트워크의 중간층은 클러스터링하는 층이다. 즉, 이 충의 목적은 주어진 자료 집합을 유사한 클러스터들(homogenous cluster)로 분류하는 것이다. 여기서 유사하다는 것은 입력 데이터들에 대한 특징 벡터 공간사이에서 한 클러스터내의 벡터들 간에 거리를 측정하여 정해진 반경 내에 존재하면 같은 클러스터로 분류하고 정해진 반경 내에 존재하지 않으면 다른 클러스터로 분류한다. 그러나 정해진 반경 내에서 클러스터링하는 것은 잘못된 클러스터를 선택하는 단점을 가지게 된다. 그러므로 중간층을 결정하는 .것은 RBF 네트워크의 전반적인 효율성에 큰 영향을 준다. 따라서 본 논문에서는 효율적으로 중간층을 결정하기 위한 방법으로 퍼지 C-Means 클러스터링 알고리즘을 적용한 퍼지 RBF 네트워크를 제안한다. 제안된 퍼지 RBF 네트워크의 학습은 크게 두 단계로 구분된다. 첫 번째 단계는 입력층과 중간층 사이에 퍼지 C-Means 알고리즘이 수행되고, 두 번째 단계는 중간층과 출력층 사이에 지도학습이 수행된다. 제안된 방법의 학습 성능을 평가하기 위하여 실제 주민등록증에서 추출한 숫자패턴에 적용한 결과, 기존의 RBF네트워크 보다 학습 성능이 개선된 것을 확인하였다.
