Recently, high-rise building with a large aspect ratio characteristics under the influence of the lateral load than the gravity load the high lateral stiffness is required. Due to larger-scale, application of each member effective is an important consideration. Therefore, in this paper, the structural analysis was performed about the lateral load against the bundle high-rise model. The distribution factor about the horizontal displacement of each elements is analyze. The members have a great influence on the horizontal displacement control in the high-rise design is checked. By applying an efficient steel is to analyze the economic efficiency.

본 논문은 첨단 재료기술의 혁신유형을 분류하는 것이다. 기존의 혁신유형 분류에 관한 연구는 전 기술 혹은 전 산업에 포괄 적용하는 개념에서 접근하고 있어 산업기술별 혁신의 고유한 특수성이 기술혁신유형에 제대로 반영되지 못하고 있다. 이에, 본 논문에서는 첨단재료기술에 한정하여 기술혁신에 대한 이해를 증진하고 연구개발 및 정책수립의 기본 틀로 활용하는데 목적을 둔 4가지의 기술혁신 유형(공급재료혁신, 수요재료혁신, 공급공정혁신 및 수요공정혁신)을 제안하였다. 혁신유형의 도출과정은 청단재료기술혁신의 특성, 원천, 과정 분석과 함께 사용자 산업과의 상호작용 분석에 근거 하고 있다. 4가지 혁신 유형별로 특정과 사례분석을 통하여 연구개발 혹은 정책수립 등의 도구로서 활용가능성과 관련 시사점을 살펴보았다. This paper is to categorize the innovation patterns of advanced materials technologies Many existing taxonomies of innovation pattern consider the whole of industries and the system sector rather than a specific sector. On the basis of the interactions between materials sector and user sectors, this paper suggests four innovation patterns, push-type material innovation, needs-type materials innovation, push-type process innovation and needs-type process innovation. This categorization of innovation pattern not only provides a new approach to the analysis of materials technology innovation processes but also has many useful implications for policymaking. Suggestions for policymakers of the materials technology are presented.

The meat consumption produces a lot of bone waste everyday. Dumping bone waste without treatment results into environmental hazards. Conventional treatment by pyrolysis is slow, inefficient and produces hazardous by-products. In the work, an investigation of bone waste incinerated using thermal plasma technology is presented. A high temperature arc plasma torch operated at 33 ㎾ was employed for the experiments. Bone waste was incinerated to remove the infectious organic matter and to vitrify the inorganic matter using plasma torch. Bone waste was reduced its 2/3 weight after the treatment. The process was highly efficient, economical, convenient, and fuel free. This method could be used as an alternative method for disposal of bone waste, small infectious animals, hazardous hospital waste, etc.
