Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.展开更多

The purpose of this study is to explore the ways adopted by tribal residents to maintain their own culture and tribal life in the process of disaster, post disaster reconstruction and post disaster adjustment. Veoveoana Village in Taiwan is an indigenous tribe that relocated after a disaster and was reconstructed and developed through tourism development. This study performed the research by participant observation and in-depth interviews on Veoveoana Village. The analytical results showed that: 1) development of the tourism industry can result in cultural reconstruction of the post-disaster tribe and maintain the people’s incomes;2) although the government constantly assists with the rehabilitation of tribal industry by various policies, the implementation cannot effectively continue and the outcome is insignificant;3) due to the gap between permanent prefabricated housing and original tribal cultural features, the residential rate is not high. According to the research findings, it is suggested that, in the process of post-disaster reconstruction, the government and private non-profit organizations should respect the intention of the majority of the indigenous people. In addition, it should cultivate professional manpower for the subsidized projects.展开更多

The establishment of tribal councils provides a communicative forum for tribal leaders, village, and the association of community development to make decisions of common tribal affairs. When disasters happen, the internal tribal response strategies and external assistance mechanisms might cooperate through either traditional or modern administrative systems. The research focused on how these organizations, while in interim housing, influenced the reconstruction and rehabilitation after disasters. The research＇s findings suggested that tribal councils, a pre-existing mechanism, seemed to be an appropriate forum for negotiation and decision-making for tribal affairs.展开更多

The aim of this prospective study was to validate the accuracy and predictability of 3D interactive quantitative surgical planning approach （IQSP）, and to evaluate the impact of IQSP on traditional surgical plans based on 2D images. METHODS： A total of 305 consecutive patients undergoing hepatectomy were included in this study. Surgical plans were created by traditional 2D approach using picture archiving and communication system （PACS） and 3D approach using IQSP respectively by two groups of physicians who did not know the surgical plans of the other group. The two surgical plans were submitted to the chief surgeon for selection before operation. The specimens were weighed. The two surgical plans were compared and analyzed retrospectively based on the operation results. RESULTS： The two surgical plans were successfully developed in all 305 patients and all the 3D IQSP surgical plans were selected as the final decision. Total 278 patients successfully underwent surgery, including 147 uncomplex hepatectomy and 131 complex hepatectomy. Twenty-seven patients were withdrawn from hepatectomy. In the uncomplex group, the two surgical plans were the same in all 147 patients and no statistically significant difference was found among 2D calcu- lated resection volume （2D-RV）, 3D IQSP calculated resection volume （IQSP-RV） and the specimen volume. In the complex group, the two surgical plans were different in 49 patients （49/131, 37.4%）. According to the significance of differences, the 49 different patients were classified into three grades. No statistically significant difference was found between IQSP-RV and specimen volume. The coincidence rate of territory analy- sis of IQSP with operation was 92.1% （93/101） for 101 patients of anatomic hepatectomy. CONCLUSIONS： The accuracy and predictability of 3D IQSP were validated. Compared with traditional surgical planning, 3D IQSP can provide more quantitative information of anatomic structure. With the assistance of 3D IQSP, traditional surgical plans were modified to be more radical and safe.展开更多

After the 2017 earthquake, the buildings in Vrisa were marked with red, yellow and green which shows different levels of damage. Also, there are some regulations to restrict the fa?ade, square meter, decoration and funding of rebuilding. By analyzing the characteristics of Vrisa village before earthquake and situation after earthquake, we came up with three reconstruction strategies from different aspects to find solutions. Meanwhile, this paper hopes to provide a reference and suggestions for similar cases of post-earthquake reconstruction.展开更多

Each of them led to significant spatial changes. The first hotel established the foundation of urbanization process in Budva, the building was too high compared to the old town walls in the surrounding and thus not well integrated. The second reconstruction was the only successful achievement. At this time, in the first detailed urban plan including hotel and its surrounding area, the conclusion was that it represents ＂high-quality, seaside-favorable ambience＂ that should not be harmed by further building expansion. The last, illegal reconstruction in 2006 resulted in over enlarged new building disrespectful of the surrounding and the previous design. Similarly, the 2008 new detailed urban plan was the creation of ＂investors＇ urban planning＂. Entirely driven by profit, it arranges building reconstructions with multiple enlargements. This study tends to point out contextual impacts of the three hotels on the surrounding area, with special focus on the last reconstruction and ＂investors＇ urban planning＂ phenomena. The applied research method is comparative, chronological analysis of the three hotels. The aim of this research paper is to inspire initiatives that will help overcoming declining and harmful synergy of architecture and new socio-economic phenomena. It is the only way leading to the significant architectural goal： creating refined, harmonized and high quality ambience.展开更多

In this context of ongoing conflict this article aims to identify, rank, and discuss the most important factors influencing post-disaster reconstruction project management(PDRPM) for housing in the Gaza Strip. A set of key factors that influence PDRPM were assembled as a result of a global literature review. A questionnaire survey was conducted, and the obtained data were analyzed using a relative importance index for each PDRPM factor. Findings are presented in six groups: housing approaches, organizational behavior, project funding, supply chain and logistics, communication and coordination, and PDRPM context. Findings indicate that the most significant factors that influence PDRPM for housing provision in the Gaza Strip are related to issues associated with financial resources. It is critical that sufficient funding should be available in order to allow organizations to undertake housing projects in an effective and efficient way. Joint efforts are required from international donors and local organizations in order to effectively manage financial resources with the ultimate goal of improving PDRPM for housing provision.展开更多
