The parents of the invention class for the gifted under the local education office showed more enthusiastic attitude to support their students, and had significantly stronger recognition that the participation of the students in the invention education for the gifted helped enter an advanced school than those under the invention classroom. However, the class contents of the invention class for the gifted under the local education office such as 'understanding the influence of the invention history and products on society', 'scientific inquiry skills for problem solving', 'technological and engineering abilities for creating an invention', 'developing knowledge and abilities about business and management by using a new invention' were not different from those under the invention classroom. In addition, discussion and presentation were not active in the class activities of the invention class for the gifted under the local education office. Therefore, the researchers should compensate and develop a program which can apply strategically differentiated class contents and class activities to the students who participate in the invention class for the gifted under the local education office by the 'Gifted Education Promotion Act'.

최근 서울시 고용 및 공간구조의 변화는 오피스 고용의 성장과 오피스 업종의 공간적 분화로 특징지워질 수 있다. 서울시 오피스 기능의 양대 성장축은 도심과 강남이며, 여의도는 도심기능의 일부를 보완하면서 고밀도의 성장을 이루어 서울시 오피스 활동은 이들 세 지역을 주요 중심지로 하는 다중심구조를 형성하고 있다. 서울시 오피스 기능은 지역에 따른 기능의 선별적인 분산이 이루어지고 있다. 즉, 전반적인 오피스 기능의 분산 경향 속에서도 도심 입지를 여전히 선호하는 오피스들은 금융${\cdot}$보험${\cdot}$광고${\cdot}$여행사${\cdot}$주요 공공 행정기관으로, 동종업체 및 관련기관과의 대면접촉과 원활한 정보교환이 많이 요구되거나 도심이 가지는 명성 및 상징성이 중요하게 작용하는 기능들이 주종을 이루고 있다. 그러나 법무서비스${\cdot}$5000대기업본사${\cdot}$건축기술서비스${\cdot}$부동산업은 도심을 벗어나 강남으로 선별적 이지를 하는 경향이 강하게 나타났다. 한편, 정부 정책에 의하여 증권가가 조성된 여의도는 증권업의 메카로서 독보적인 위치를 점하고 있다.
