Even though the life of a building fully remains, early complete withdrawal re-construction is carried out because of internal components fashioned. However, remodelling is activated by legal recently and the remodeling technology is increasing for sustainable development. This study grasp the internal components remodeling technology of Korea, America and Japan through analysis of patents so as to find out the proper direction of remodelling technology of internal components.

Recently, Domestic construction industry is confronted with a new phase by increasement of stock and elation of the concern about environment. In particular, the focus on remodeling as an altanative of the reconstruction system that squanders resources and creates massive construction waste, has increased. However, current remodeling methods are being obstructed factor, because design has not considered the remodeling at the beginning of the construction. The purpose of this study is to search for the improvement of component joint for efficient remodeling. Field survey is conducted on the components grouped by spaces(living room/bed room/kitchen/bathroom) of unit living at 6 construction sites in Seoul & countries. As a result, total 228 component joints are selected and classified according to interface condition and problem pattern.

Multi Housing design has not considered the remodeling even at the beginning of the construction. This severely hindered systematic maintenance, providing fundamental causes of consuming society. In general, in about 20 years when the buildings become too old, they are brought down or removed with a trail of waste left behind. In addition, since the current remodeling or future remodeling type is a general remodeling that leaves only a frame, some question the role of the remodeling as a solution to the reconstruction from economically and environmentally efficient aspects. This study intends to find a solution for long-life span multi-family housing design, promoting sequential remodeling by stating the life cycle of components. Problems were identified by analyzing joints, design and construction of multi-family housing based on the previous researches. Conclusion from characterization of the design plan according to joint parts can be summarized as the following firstly, the problem of the wet was seen in joints between the structure and a finishing materials and ones between separate finishing materials. Secondly, the problem of overlap was frequently seen in joints between the structure and a door/window, ones between a door/window and a finishing materials, and ones between a finishing materials and an electrical/mechanical device.

Deterioration of the educational facilities built before 1985 is a serious situation. The purpose of this study is to present the efficient remodeling method of old educational facilities. This paper, part II, presents the systemic and synthetic judgment method of deterioration grade of structural components. Deterioration grade of the whole structural components are judged by synthetic evaluation score which is the total of the score of ten evaluation items. And we added the importance coefficient of the viewpoint of four performance to each evaluation item.

This study is to evaluate the classification system of rural-villages remodeling components which is provided for improving the quality of life for rural community by improvement of settlement environment. To achieve this, rural-villages remodeling components are classified according to the spatial structure of rural area through analysis of literature, then we have examined the applicability through case studies after modification work which is based on experts's discussion and rearrangement by pilot investigation of researcher. In the classification system of rural-villages remodeling classified productivity area, residential area, community area in first group and this classification is divided into 6 space to production, 4 space to residence, 5 space to community in second group by literature search, pilot investigation of researcher and field survey. The subject elements surveyed a total of 123 through the literature search, additionally, 1 element at a space to production and space to community in field survey for types in zoning cases. As a result, categories and items are decided that it is included 125 target elements.

Lastly, the problem of filling occurs in the process of concealed joint of adjacent components and was seen in joints between the structure and an electrical or mechanical device. Therefore, the dry processing which replaces wet joint was seen in joints between the structure and a door, ones between the structure and a finishing materials, ones between a gypsum board and electrical device, and ones between a water pipe and a tile finishing. And a process of separating the area of jointed parts in order to eliminate the problem of overlap was seen in joints between a door and a finishing material and ones between a gypsum board on the ceiling and a light. Lastly, an analysis of a process of exposing concealed parts indicated that the problem of filling could be applied to joints between the structure and an electrical or mechanical device and ones between a finishing material and a mechanical device. This study sought out methods to apply Environment Friendly Multi Housing Remodeling that allow easy remodeling as part of environment- preserving policies. It also contains basic data useful to implement long-life houses in the future by presenting a comprehensive design standard for them

This thesis investigates the behavior of precast wall systems with a new vertical connection which are proportioned by the displacement based design. The proposed precast wall systems are supposed to provide additional spaces and seismic strengthening in remodeling existing residential buildings. For a fast remodeling constructions using PC walls require an efficient, economic fabrication method. A C-type vertical connections for PC wall systems is proposed for transfer of bending moment between walls in the vertical direction while a shear key in the center of wall is prepared to transfer shear forces by bearing. The proposed vertical connection allows us easy fabrication because of different direction of slots at the edges of wall. The dimension of C-type connection components are determined by engineering models and a series of test.

Controlled remodeling of the extracellular matrix (ECM) is essential for cell growth, invasion and metastasis. Matrix metalloproteinases (MMPs) are a family of secreted, zinc-dependent endopeptidases capable of degradation of ECM components. The expression and activity of MMPs in a variety of human cancers have been intensively studied. They play important roles at different steps of malignant tumor formation and have central significance in embryogenesis, tissue remodeling, inflammation, angiogenesis and metastasis. However, increasing evidence demonstrates that MMPs are involved earlier in tumorigenesis. Recent studies also suggest that MMPs play complex roles in tumor progression. MMPs and membrane type (MT)-MMPs are potentially significant therapeutic targets in many cancers, so that designing of specific MMP inhibitors would be helpful for clinical trials. Here, we review the pleiotropic roles of the MMP system in hematological malignancies in-vitro and in-vivo models.

무당개구리 상처치유 과정 중 재생되는 피부 상피세포의 형태학적 특성을 관찰하기 위하여 투과전자현미경을 이용하였다. 상처유도 추 재형성과정 중의 표피는 재생되는 상피세포에 의해 $3\sim4$층을 형성하였으며, 세포들의 크기는 상충에서 하층으로 갈수록 크게 신장되어 있음이 관찰되었다. 세포 간격 또한 세포층의 기저부를 향할수록 넓어졌다. 기저층에 위치한 세포는 세포질 돌기들을 내어 데스모소옴이 형성되어 있었고, 원주형이었다. 기저막이 형성된 세포들 사이에는 원기세포들이 위치하고 있었으며, 이 세포들은 불규칙한 난형 또는 타원형으로 세포의 크기는 다른 세포들에 비해 작게 관찰되었다. 따라서, 상피조직은 재생될 때 원기세포들의 분열과 이동이 동반되어야 하므로, 무당개구리 상피는 시간이 경과함에 따라 정상조직과 동일하게 재생될 수 있을 것으로 생각된다. 본 연구에서 상처가 치유된 시점으로 확인된 31일 경의 상피조직의 관찰 결과 역시 추측했던 점과 일치되어 정상과 동일한 조직학적 구성을 이루고 있었다. 또한 재형성 과정 중 상피는 피부가 정상조직으로 형성되기 전까지 수분유실을 막는 방어벽으로서의 기능과 허물을 벗는데 관여하는 것으로 확인되었다.
