  • The purpose of this study is to improve the learning speed of an ammunition stockpile reliability classification artificial neural network model by proposing a normalization method that reduces the number of input variables based on the characteristic of Ammunition Stockpile Reliability Program (ASRP) data without loss of classification performance. Ammunition's performance requirements are specified in the Korea Defense Specification (KDS) and Ammunition Stockpile reliability Test Procedure (ASTP). Based on the characteristic of the ASRP data, input variables can be normalized to estimate the lot percent nonconforming or failure rate. To maintain the unitary hypercube condition of the input variables, min-max normalization method is also used. Area Under the ROC Curve (AUC) of general min-max normalization and proposed 2-step normalization is over 0.95 and speed-up for marching learning based on ASRP field data is improved 1.74 ~ 1.99 times depending on the numbers of training data and of hidden layer's node.

  • 우리 협회는 지난 11월 26일 오후 2시 협회 대강당에서 '건축설계의 국제경쟁력 확보 및 전문화 방안'을 주제로 토론회를 개최하였다. WTO출범과 건축설계시장개방 등 급격한 대내ㆍ외적 환경변화에 처해 있는 우리 건축계의 국제경쟁력 확보 방안을 마련하기 위해 열린 이날 토론회에서는 경쟁력 확보를 위해 건축설계사무소마다 다양한 전문분야를 확보하고, 건축설계 생산성 향상을 위해 설계업계와 구조, 설비 등 관련 전문분야가 협력체제를 구축해야 하며, 건축의 상품성과 문화예술성이 함께 고려된 건설관련 법안이 마련돼야 한다는 주장이 제기됐다. 이날 서울시립대 최찬환교수는 '건축설계의 경쟁력 확보 방안'이란 주제발표를 통해 해외건설업계의 국내진출에 대응하기 위해서는 설계사무소가 전문성과 효율성을 확보해야 한다고 강조하면서 전문영역을 크게 주거, 상업시설, 공공시설, 교육문화시설, 사회복지시설, 교통 및 운수시설 등으로 구분하였다. 최교수는 또 외국업체에 의한 국내시장 잠식을 막고 우리가 해외에 진출하기 위해서는 해외건설업체와 협력해 정보와 기술, 경험 등을 지원받아야 하고 R&D에 대한 투자를 적극적으로 해야한다고 강조했다. 이어 '건축설계의 전문화'에 대해 주제발표를 한 강원대 박경립 교수는 국내 건설관련문제점 개선과 대외경쟁력 강화를 위해 현재 입법추진되고 있는 건설산업기본법이 건축설계의 독자성과 전문성을 고려하지 않고 있다고 지적하면서 이에 대한 보완필요성을 제기하였다. 박교수는 또한 건축설계분야가 갖고 있는 전문성과 함께 '건축문화'라는 사회문화적 측면의 중요성이 인식돼야 한다며 건축의 상품성과 문화예술성이 함께 고려된 건설관련 법안이 마련돼야 한다고 지적했다. 박교수는 이밖에도 사회발전에 따른 새로운 전문영역의 개발로 실내 설계와 도시설계를 예로 들었으며 정보화에 맞게 고도의 전문성을 바탕으로 Network체계를 구축하고 그 핵심은 건축사협회에 정보Network를 구축하여 활용하는 것이라고 제안했다. 한편 주제발표 후에는 약 3시간여에 걸쳐 이문보(동국대 교수), 손세관(중앙대 교수), 이병담(현대산업개발 부사장), 김인호(국방부 건설기술과장), 유경철(삼육건축사사무소 대표), 이관영(본 협회 이사)씨 등 건설ㆍ건축관계자들이 참가한 종합토론이 이어졌다. 이 자리에서는 사회의 인식에 앞서 건축계 내부적으로 전문성과 효율성의 확보에 나서야 한다는 의견과 함께 무한경쟁속에서 우리 건축설계의 경쟁력을 높일 수 있다는 다양한 의견들이 제기되었다. 본지에서는 이번 토론회의 주제발표 내용을 요약 정리하여 게재한다.
