  • Due to the construction union's inefficient manner of carrying out their construction projects, lot's of conflicts and arguments among the union members are happening, so the proper model of reconstruction and process at each level of projects are also being recognized as an important part of the industry. So I would like to present an ideal process model of home reconstruction industry. Here below I'm presenting the benefits of this model when its applied properly. Through the study of information gained from the survey of residents, benefits such as AHP, analysis of SPSS, reduced construction time, budget cut, etc. will be produced

  • This paper describes an algorithm that improves 3D reconstruction result using a multi-sensor fusion disparity map. We can project LRF (Laser Range Finder) 3D points onto image pixel coordinatesusing extrinsic calibration matrixes of a camera-LRF (${\Phi}$, ${\Delta}$) and a camera calibration matrix (K). The LRF disparity map can be generated by interpolating projected LRF points. In the stereo reconstruction, we can compensate invalid points caused by repeated pattern and textureless region using the LRF disparity map. The result disparity map of compensation process is the multi-sensor fusion disparity map. We can refine the multi-sensor 3D reconstruction based on stereo vision and LRF using the multi-sensor fusion disparity map. The refinement algorithm of multi-sensor based 3D reconstruction is specified in four subsections dealing with virtual LRF stereo image generation, LRF disparity map generation, multi-sensor fusion disparity map generation, and 3D reconstruction process. It has been tested by synchronized stereo image pair and LRF 3D scan data.

  • The policy introduced recently in order to promote small-size reconstruction housing projects for rehabilitating downtown area consists of aged multi houses has been little practiced, as preferential provisions for such projects are more likely applicable for large projects. Several expert interviews and surveys were conducted to find efficient clauses to overcome the problems and their relative weights. As the results, it is revealed that 'relation of floor area ratio' and 'relaxation of building height limit criteria' are the most effective whereas 'purchasing and operating of residents' common facilities with public fund' is little. The study results would be a great interests for public institutions to rebuild aged housing area without destroying local communities and to provide socially disadvantaged class with rental housing at the same time.

  • In this study, to solve the problem of the Association-led Housing Reconstruction Business (AHRB), as an alternative to the AHRB, the reliability of the Trust company-led Housing Reconstruction Business (THRB) is verified. To this end, the AHRB and the THRB comparison analyses were performed for the project period, income and expenditure, and the calculation of the Reconstruction Charges (RC). The results of the study are as follows: First, the THRB's business period is shorter than the AHRB's. Second, the THRB's business value is likely to be superior to the AHRB's. Third, due to differences in the calculation period of excess profit for housing reconstruction and the cost items related to implementer, the THRB's RC will be less than the AHRB's RC. Thus, the stability of the THRB has been partially verified as an alternative to the AHRB. The THRB is expected to expand further in the future.

  • In various urban renewal projects related to real estate, developer in order to conduct the business, must get real estate inside project section directly or receive the consent for project from the owners. It must be carried out by consultation. When it fails, developer, in order to get ownership, adopts 'the Right of Claim for the sale' which has forcibleness. However, because the procedure for implementation of the right of claim for the sale is not clear, conflict between stakeholders is caused and it causes extension of period. Therefore, after examining judgments and references of judicial power for administrative litigation of the Right of Claim for the sale, by researching stakeholders of the housing rebuilding project and based on the results, finding out differences of stakeholders' recognition according to their position and problems of exercising procedure of the Right of Claim for the sale, and by presenting improvement plans of the system of the Right of Claim for the sale, contributing the success of the housing rebuilding project is the purpose of it.

  • In case of loss of many teeth due to dental caries or periodontal disease, improvement of masticatory function and aesthetics can be obtained through implant treatment. However, if the patient does not have a normal intercondylar relationship, it is difficult to achieve an ideal occlusal relationship with only prosthetic treatment. In particular, oral reconstruction with orthodontic treatment or orthognathic surgery is necessary for patients with mandibular prognathism. However, if the posterior occlusion collapses due to severe caries or periodontal disease, orthognathic surgery may be difficult. The occlusal vertical stop is very important for the stability of the mandibular position during occlusal reconstruction through orthognathic surgery. The patient in this case had posterior occlusion collapsed due to the caries of a large number of posterior teeth, and showed mandibular prognathism and long face. We planned a full arch restoration with orthognathic surgery and extracted the hopeless teeth. To secure the vertical stop required for orthognathic surgery, the implant was placed before surgery. After the orthognathic surgery and the final prosthesis application, the results were satisfactory for the improvement of the aesthetics and the restoration of the masticatory function.

  • Because a procedure is complicated and various related parties participate in the redevelopment and reconstruction project, it can be extended to diverse disputes when the relation with the related parties is smoothly adjusted. In particular, when the dispute occurs in a phase of occupancy after the complete construction, the regional residents-centric association must give up many rights of invisible parts caused by the construction company's profit maximization because they are short of professionalism about the business. Accordingly, this study is aimed at providing the construction project manager's dispute and claim process for responding to the dispute or claim reasonably and for obtaining the client's (association) rights for the reconstruction project, and at developing the checklist for obtaining the necessary documents by each phase, when the dispute or claim is made by the association against the construction company after the completion of construction. Through this study, the association can obtain the related documents in advance and can implement the reasonable response data when the dispute or claim occurs due to it. Also, it will enable the construction manager to analyze the project costs reasonably and will reduce the estimated wastes. That is, the work efficiency is expected to be improved.

  • Recently, as the frequency of natural disasters has increased, causing enormous human and material damage, the importance of managing disasters is emphasized. In particular, as the concept of Build Back Better becomes meaningful, it has appeared that considering it during Post-disaster Reconstruction is a necessity. Therefore, in this study, the relative importance evaluation and correlation analysis were performed for each influencing factor through the derivation of the influencing factors that should be considered during the reconstruction approach stage of reconstruction after disasters, and a survey of overseas disaster-related experts. As a result of the analysis, 'Adaptability to the environment changes in the future was derived as the most significant influencing factor. It seems that the results of this study can be used as basic data when carrying out the reconstruction project.
