Abstract: Recently, revised certification of Building Energy Efficiency Rating System has been distendedly implemented in public buildings. The Ministry of Land, Infrastructure and Transport in Korea is promoting a Green Remodeling pilot project and proceeding a variety of researches related to the method of Energy Efficiency improvement. The aim of this study was to compare the amount of building energy consumption by improving envelope systems such as curtain wall, window, and wall system of deteriorated public buildings. By improving the envelope system, heating energy consumption has been reduced about 37%.

Abstract: Industrialization process experiences the" brilliant -fading - Renaissance". The spatial form of old industrial area is an important part of the space structure of city, and is the key area of the use of land and the refreshment of city. Heavy chemical industry and enterprises is the centre of old industrial area of Baotou city, it benefits our economics, and however, it threatens the safety of environment. The study of old industrial area helps to improve the city's economic benefit, ecological benefit and competitiveness. This paper will study the spatial form evolution of old industrial area, analysis characteristics of spatial form evolution of old industrial area, and put forward certain recommendations of Baotou old industrial district remodeling.

Abstract: The complex parts, like block engine or inside panel door, represent a real challenge for 3D modeling with modern parametric 3D CAD systems if we intend to reuse the modeling for future modifications. The complexity of the part generates a large number of parameters and parametrical dependencies that is difficult to manage and even difficult to change for modifying the part, often, for big changes, making it easier to remodeling the part from the beginning. In this paper is presented a new method of parametric and hierarchical 3D modeling that allows easy future modifications of the part. This paper also presents the implementation of this new method in Catia V5 and the validation for a number of CAD models.

Abstract: Setting relationship of the texture coordinates with the object’s surface vertex points was the main method of texture mapping, but if depart from the modeling software; it would not get the vertex coordinates of the object. This paper describes the technique based-on OSG to remodeling the rule polyhedron and realizes the texture mapping for each side of the object, and get the desired results.

Abstract: Residential houses and civil buildings in China were mainly low-rise buildings before 1980s. With the rapid development of urban construction, urban land became more and more scarce. Thus in recent years, it becomes increasingly popular nationwide to add more stories to existing building for its particular techno-economy advantages. Adding-storey plays an important role in mitigating the pressure of demand for more building sites, improving the living condition，and accelerating the modernization progress of cities’ shabby zones. In this paper, a brief review was presented on the evolution, status-quo and trends of the adding-storey of existing buildings in China, and three new adding-storey methods using passive control technology were introduced, which can be used for peers' reference.

Abstract: A series of five shear wall specimens were tested under constant axial stress and reversed lateral cyclic loading in order to evaluate the seismic retrofit methods that had been proposed for shear walls with new openings. The test results showed that the failed specimens had shear fractures and two different retrofit methods had different effects on the strengths of each specimen.

Abstract: Bone microstructure and its functions are maintained by the activity of bone cells such as osteoclast for bone resorption and osteoblast for bone formation. In this study, we examined the role of osteoclast on the formation of the preferential orientation of biological apatite (BAp) as a bone quality parameter using OPG-KO and op/op mouse models in which the expression of osteoclast increases for osteoporosis and decreases for osteopetrosis. The orientation degree of the BAp c-axis was analyzed by a microbeam X-ray diffraction system. We found more decrease in the preferential alignment of the BAp c-axis along the longitudinal direction of bone in the femoral bones of both OPG-KO and op/op mice at 12 weeks compared with normal control mice. We concluded that changes in the amount and activity of osteoclast affect BAp alignment, resulting in the degradation of bone microstructure in osteoporosis and osteopetrosis.

Abstract: We conducted work to investigate fatigue cracking and repair in bone, in which we discovered the mechanism by which bone is able to detect the presence of microscopic cracks and thus initiate repair processes. This investigation has made use of theoretical and applied fracture mechanics, in combination with cell biology. It is the first example of a completely-understood mechanism showing how living cells can respond to mechanical stimuli.

Abstract: A series of three shear wall specimens were tested under constant axial stress and reversed cyclical lateral loading in order to evaluate the seismic retrofit that had been proposed for the shear wall with the opening induced by remodeling. One of these specimens was tested in the as-built condition and the other two were retrofitted prior to testing. The retrofit involved the use of carbon fiber sheets and steel plates (a thickness of 3mm) over the entire face of the wall. The test results showed that the failed specimens had shear fractures and that two different types of retrofitting strategies had different effects on the strengths of each specimen.

Abstract: Dental implants have been extensively used in prosthetic dentistry over the last two decades. Clinical experience shows that the healing and osseointegration process can heavily influence the success of the implantation. It is critical to understand the damage extent in different time frames. This paper aims at exploring the mechanical damage of dental implantation over the healing process. The 3D finite element analysis (FEA) models were developed based on computerised tomography (CT) scan technology to investigate the load-induced damage of interfacial osseointegration, as well as cortical and cancellous bone tissues. Unlike the existing linear finite element (FE) stress analysis, this study takes into account the damage accumulation and micro-crack nucleation under a framework of bone/interface remodelling. This study reveals the damage in the surrounding bone tissues and bone-implant interfaces at different stages of the healing process, and consequently premature load tolerances are suggested.
