  • Recently, apartment-remodeling project is booming since various reconstruction controls are tightened. However, the project has difficulties because management systems used for apartment-remodeling projects are not available. Identifying and analyzing risk factors that are required for risk management, this paper suggests the risk level through paired comparison performed by AHP method and probability assessment for risk level analysis. It is expected that this research will be utilized to minimize the risk of apartment remodeling project and for basic materials to perform the project and helpful to change newly build-oriented construction into sustainable industries. Hereafter using the risk factor analysis data of this paper for this research project, risk management model is considered to be constructed.

  • Wildfire disasters in the United States impact lives and livelihoods by destroying private homes, businesses, community facilities, and infrastructure. Disaster victims suffer from damaged houses, inadequate shelters, inoperable civil infrastructure, and homelessness coupled with long-term recovery and reconstruction processes. Cities and their neighboring communities require an enormous commitment for a full recovery for as long as disaster recovery processes last. State, county, and municipal governments inherently have the responsibility to establish and provide governance and public services for the benefit and well being of community members. Municipal governments' comprehensive and emergency response plans are the artifacts of planning efforts that guide accomplishing those duties. Typically these plans include preparation and response to natural disasters, including wildfires. The standard wildfire planning includes and outlines (1) a wildfire hazard assessment, (2) response approaches to prevent human injury and minimize damage to physical property, and (3) near- and long-term recovery and reconstruction efforts. There is often a high level of detail in the assessment section, but the level of detail and specificity significantly lessons to general approaches in the long-term recovery subsection. This paper aims to document the extent of wildfire preparedness at the county level in general, focusing on the long-term recovery subsections of municipal plans. Based on the identified challenges, the researchers provide recommendations for better longer-term recovery and reconstruction opportunities: 1) building permit requirements, 2) exploration of the use of modular construction, 3) address through relief from legislative requirements, and 4) early, simple, funding, and the aid application process.

  • Gwanghwamun was dismantled and displaced to the east side of the palace, at that time, the Chosun Government General Building was constructed in the Gyeongbokgung palace. After the Korea war, it remained as a stonework as a result of the fire. In 1968, The Gwanghwamun came back in front of the palace. Then, why it was rebuilt in the 3rd Republic period? What was the reason for selecting concrete? Since the May 16 coup, the military regime had been utilized palace and surrounding urban space to show a visible practice of modernization. Attempting the combination of modern technology in the 1960s and traditional cultural property and reconstructing a city as a pretext called Cultural Heritage conservation was a typical mechanism of the 1960s. In this study, I start by assume that reconstructing Gwanghwamun(1968) was a part of project to change the surrounding urban space of Gwanghwamun than to preserve cultural assets. Two main contributions of the study are following. First, I collect availabe data on the reconstructing surrounding urban space of the Gwanghwamun and re-organize them in chronological order to make them as fragments of a map. Second, I analysis and identify the nature and phase of the Gwanghwamun reconstruction.

  • This paper summarized the safety diagnosis method in the field of durability among the structural safety suggested in the safety diagnosis manual of the reconstruction project and analyzed the safety diagnosis case. It is expected to be a reference material for safety diagnosis in the field of durability by pointing out cases that are wrong during existing safety diagnosis and cases where diagnostics are likely to make errors.

  • In the case of failed fixed implant prosthesis accompanied by abutment screw fracture, fractured screw fragment must be removed to use the existing implant fixtures. A 61-year-old male patient, who had a failed maxillary fixed implant prosthesis accompanied by three abutment screw fracture, hoped to reconstruct the maxillary implant prosthesis, while maintaining the existing implant fixtures. To use the existing implant fixtures, fractured screw fragments were removed. A maxillary implant overdenture using available existing implants was planned. Bar-attachment with Locator was used for implant splinting, denture stability, and retention. Final impression was taken after treatment of peri-implantitis. Jaw relation registration was taken to evaluate available interarch space for bar-attachment. After fabricating bar-attachment, centric relation was taken. Implant overdenture using bar-attachment with Locator was delivered after wax-denture evaluation. This case report showed that a satisfactory clinical result was achieved by implant overdenture using existing implant fixtures in a maxillary edentulous patient.

  • Remodeling the existing building structure by recycling has great advantages compared with reconstruction in terms of environmentally contributions and reduced use of national resources. And no matter the existing floor area ratio, extension up to 30% of the exclusive using area and short project period have made remodeling a good alternative to reconstruction. However, the residents of aged housings that were being remodeled are either abandoning the remodeling project and turning to reconstruction. The main reason is remodeling project cannot increase the number of householders. In principal, it is prohibited to increase the number of floors during remodeling due to matters of safety. That is, all remodeling construction costs are borne by the residents, which leads to great financial pressure. Therefore, in order to improve these conditions, the residents' burden of remodeling charges should be reduced, and one of the ways to do so is to increase the number of householders. In this study, there will be suggestions of alternatives, including the story increase during remodeling, and compare the burden of remodeling charges on each of the residents, between proposed alternatives and the current remodeling plans by calculating the construction costs in order to prepare a foundation for a system that will promote remodeling.

  • 유전자 분석기술의 발전은 지놈 프로젝트(genome project)와 햅맵 프로젝트(hapmap project)를 가능하게 하였으며 이제는 맞춤형 진단 및 신약 개발 등 실제 사업의 구체화를 가져오게 하였다. 실제 사업에 적용시키기 위해서는 비용 절감의 문제를 해결해야 한다. 그래서 대용량의 유전자형(genotype)데이터를 정확하고 빠르게 일배체형(haplotype)으로 재구성해 줄 수 있는 시스템이 생물 산업 및 제약 산업에서 제기되어 지고 있다. 기존의 연구에서 비록 정확성이 높은 알고리즘들이 개발되어 있지만 기존의 방법들은 계산에 필요한 양이 크기 때문에 대용량 데이터에 대한 처리가 불가능하였다. 우리가 제안하는 시스템은 대용량 데이터를 유동적인 크기로 블록을 분할하여 대용량 데이터 처리 문제를 해결하였다. 또한 나누어진 블록에서 나타나는 모호한 이형접합체(heterozygote)의 위상(phase)의 결정 과정에 LD기반의 블록 분할 방법을 이용함으로써, 추론된 결과의 정확률을 높였다. 구현된 시스템의 성능평가는 ms로 구성한 인공데이터를 사용하여 수행하였다.

  • In the framework of the EU funded project NURESAFE, the subchannel code CTF and the neutronics code DYN3D were integrated and coupled on the NURESIM platform. The developments achieved during this 3-year project include assembly-level and pin-by-pin multiphysics thermal hydraulics/neutron kinetics coupling. In order to test this coupling, a PWR rod ejection transient was simulated on a MOX/UOX minicore. The transient is simulated using two different models of the minicore. In the first simulation, both codes model the core with an assembly-wise resolution. In the second simulation, a pin-by-pin fuel-centered model is used in CTF for the central assembly, and a pin power reconstruction method is applied in DYN3D. The analysis shows the influence of the different models on global parameters, such as the power and the average fuel temperature, but also on local parameters such as the maximum fuel temperature.
