The thermal and condensation performance of steel stud walls are monitored in steel-framed schools of Ee-Wol Elementary School and kindergarten using temperature and humidity sensors installed. The monitoring process carried out during the summer and winter period, shows decrement effect of the external heat flow to be quite remarkable and excellent. And steel stud walls provides a highly efficient time-lag effect in spite of its light weight property, with 30 minutes to 4 hours time-lag for external heat flow, which variation mainly depends on its location of each part of the wall. Any condensation phenomena are not observed in either external or internal surfaces.

The study is a Post-Occupancy-Evaluation on newly constructed steel framed school buildings sponsored by POSCO, and presents alternative tactics for planning and programming for the kind of project. The schools in concern are Seowha Primary School(Incheon city) and Galma Primary School(Daejeon city) which were completed in February 1999 and since occupied. The POE-2000 study results had to be compared to the POE-1999 which dealt on Jigog Primary School(Pohang city) and Iwol Primary School(Jincheon township) to develop an improved project tactics. In this reason we had to use the same questionnaire forms envisaged by the former study, ie. POE-1999. To begin with the same study format, it might be appropriate to differentiate whether a 'satisfaction' comes from the 'steel framed construction' or from the 'newly built environment'. However it was difficult with the POE-1999. As the intention to compare the 4 school building were the firstly achieved objective of this study that we had to continue to apply the same format and the analysis procedure. Except this condition, everything the POE-1999 conducted were valuable to this POE-2000. The satisfaction survey form includes 36 questions for individual items and 2 questions for general items.

공동주택단지 및 학교 및 근린시설의 경계방음벽으로 제시한 식생형 방음벽을 설계하고 소음감쇠성능실험을 실시하였다. 본 논문에서 제시한 식생형 방음벽은 일정한 형태의 유닛을 방음벽 형태의 구조물에 걸이식으로 적층하여 구성된 것으로서, 유닛내부에는 식재 및 토양을 포함하고 있다. 이 방음벽의 음향적인 장점은 토양 및 식재를 이용한 흡음뿐만 아니라 확산형상의 방음벽에서 표면 확산으로 인해 음에너지가 분산되어 소음을 저감할 수 있을 것으로 예상된다. 먼저 1/10 축소모형 실험을 통해 소음감쇠성능에 가장 적합한 방음벽 유닛의 크기를 조사하였으며, 설계된 도면에 따라 1/2축척의 식생형 방음벽을 실제높이 2 m, 길이 5 m로 제작하여 소음감쇠실험을 진행하였다. 식물을 담을 수 있는 총 1,137개의 식생블록은 약 $10{\times}10{\times}9cm$ 크기로 합성목재를 활용해 제작하였으며 이 블록들을 방음벽에 설치하여 자립형 구조를 가진 식생형 방음벽을 완성하였다. 연구결과, 평면형 방음벽보다 블록식 방음벽이 약 7 dB 더 높은 삽입손실을 나타냈으며, 식생블록의 크기는 삽입손실효과가 큰 $20{\times}20cm$의 크기가 적정한 것으로 나타났다.
