In this study, a real-sized experimental equipment (pilot plant) was built at the site based on the preliminary research data to develop a movable separator for the mixed construction waste that can be implemented in agricultural areas to review its feasibility through the evaluation of its separation efficiency by waste types. The final construction of the movable separator and experimental results of the separation efficiency are summarized as follows. 1) The separation performance according to the blade type was the best for the combustible wastes either with 26 numbers of L-type blades and 32 numbers of pin type blades. As far as combination of blade types, when the L-type and pin-type were combined, the best separation efficiency was achieved. 2) The separation efficiency for waste wood by the conveyor type and angle of inclination (slope) of the trommel was the best when the conveyor had ribs of seagull shape with the angle of inclination 45°. 3) The separation efficiencies by process showed that 65.9% was separated as inorganic demolition wastes, 18.2% as waste woods, and 16.0% as combustible wastes at conveyor speed of 2-3 rpm, and the error rate was the least from the waste types generated in the dismantle site.

The questionnaires, interviews, and data analysis are performed to improve the current system of safety diagnoses for the reconstruction decision of residential buildings. The results of those activities are as follows. (1) The current system of the pre-qualification in safety diagnoses is not capable of objectivity, impartiality, and specificity. Thus, the public institutions with specificity should carry out the pre-qualification for reliable and organized evaluation. (2) The level of pre-qualification should be strengthened. (3) It is necessary to improve related provision to guarantee practicality of pre-qualification verification system. (4) It is reasonable judgment to obligate verification system of result report on related upper law, because analysis result basis become known titularly though the practice of verifying a safety diagnosis result report is prescribed not in duty but in recommendation under current basis. (5) The deadline for making application must have an upward tendency settlement considered durability of structure in the long term to reduce waste of resources. (6) The current provision and manuals for safety diagnosis to adopted to be adjust to masonry structure and PC structure.

이 글은 최근 에너지, 교통, 농업 등의 분야에 대한 논의에서 부각되고 있는 전환 및 전환관리에 대한 이론들을 정리하고 있다. 지난 30여년 간 과학기술학, 혁신이론 등에서는 사회와 기술이 서로 떼어놓을 수 없는 시스템적 속성을 갖고 있음을 강조해왔다. 전환 이론에서는 사회-기술의 시스템적 속성에 초점을 맞춰서 이러한 시스템을 어떻게 사회적으로 바람직한 방향으로 변화시켜 나갈 것인가를 다루고 있다. 이 글에서는 전환이론의 이론적 배경, 주요 주장, 관련 논쟁들을 소개하면서 이에 비추어 한국의 에너지 정책이 사회와 기술에 대한 고전적 견해를 갖고 있으며 행위자들에 대한 행태적 가정을 간과하고 있음을 결론에서 지적하고 있다.
