The Planning, Organization and Management of Post-disaster Reconstruction of the Lushan Earthquake Based on the Local as the Main Body

A new organization and management mechanism with the local government as the main body was created during the post-disaster reconstruction of the "4. 20 " Lushan earthquake,in which the experiences and lessons were drawn from the "5. 12"Wenchuan earthquake. 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.

Multiscale Characteristics and Connection Mechanisms of Attraction Networks:A Trajectory Data Mining Approach Leveraging Geotagged Data

Urban tourism is considered a complex system,and multiscale exploration of the organizational patterns of attraction networks has become a topical issue in urban tourism,so exploring the multiscale characteristics and connection mechanisms of attraction networks is important for understanding the linkages between attractions and even the future destination planning.This paper uses geotagging data to compare the links between attractions in Beijing,China during four different periods:the pre-Olympic period(2004–2007),the Olympic Games and subsequent‘heat period’(2008–2013),the post-Olympic period(2014–2019),and the COVID-19(Corona Virus Disease 2019)pandemic period(2020–2021).The aim is to better understand the evolution and patterns of attraction networks at different scales in Beijing and to provide insights for tourism planning in the destination.The results show that the macro,meso-,and microscales network characteristics of attraction networks have inherent logical relationships that can explain the commonalities and differences in the development process of tourism networks.The macroscale attraction network degree Matthew effect is significant in the four different periods and exhibits a morphological monocentric structure,suggesting that new entrants are more likely to be associated with attractions that already have high value.The mesoscale links attractions according to the common purpose of tourists,and the results of the community segmentation of the attraction networks in the four different periods suggest that the functional polycentric structure describes their clustering effect,and the weak links between clusters result from attractions bound by incomplete information and distance,and the functional polycentric structure with a generally more efficient network of clusters.The pattern structure at the microscale reveals the topological transformation relationship of the regional collaboration pattern,and the attraction network structure in the four different periods has a very similar importance profile structure suggesting that the attraction network has the same construction rules and evolution mechanism,which aids in understanding the attraction network pattern at both macro and micro scales.Important approaches and practical implications for planners and managers are presented.

Application of Structuration Theory and Activity Theory in Enterprise Resources Planning Systems Implementation for Universities

An integration of organization culture in the conceptualization and development of Enterprise Resource Planning Systems （ERPs） is critical for an organization to reap potential benefits of the system. In this paper, the authors present an analytical approach through the Structuration Theory： How a university can assess its culture for the purposes of design and development of the ERPs. The authors extend the Structuration Theory by integrating it with the Activity Theory to provide the means of evaluating the activities that the system is to perform. The modified Orlikowski model is applied to depict the relationship between institutional properties, human agents, and technology in the university setup and how this offers a more inclusive approach to ERP systems development and implementation.

Influence of Position and Radiation Technique on Organs at Risk in Radiotherapy of Rectal Cancer

The influence of the position and radiation technique on the organs at risk（OARs） in radiotherapy of rectal cancer was evaluated. The relationship between the volume of irradiated small bowel（VSB） and acute bowel toxicity was determined. A total of 97 cases of rectal cancer were retrospectively randomized to receive radiotherapy with the designated treatment positions and radiation plans. Among 64 patients in the supine position, 32 patients were given three-dimensional conformal radiotherapy（3DCR） and 32 patients were subjected to intensity-modulated radiation therapy（IMRT） respectively. The rest 33 patients were treated with 3DCRT in the prone position with a belly board. The VSB was calculated for doses from 5 to 45 Gy at an interval of 5 Gy. With prescription dose in planned target volume（PTV） of 50 Gy, the dose distribution, conformal index for PTV（CIPTV）, dose-volume histogram（DVH） of OARs, the correlation of VSB and the acute toxicity were compared. The results were shown as follows：（1） Among the 3 methods, there were no differences in PTV＇s converge including V95 and D95;（2） For IMRT under a supine position, CIPTV was closest to 1, the mean dose of small bowel decreased（P〈0.05）, and the mean VSB from V30 to V45 significantly decreased（P〈0.05）.（3） For 3DCRT with a belly board under a prone position, the mean dose and the mean VSB from 40 to 45 Gy were less than those for 3DCRT under a supine position（P〈0.05）;（4） Mean proportion of VSB was significantly greater in the patients experiencing diarrhea grade 2-4 than in those with diarrhea grade 0-1 at dose levels from V30 to V45（P〈0.05）. It was concluded that for the radiotherapy of rectal cancer, IMRT technique might decrease the high-dose VSB to reduce the risk of acute injury. 3DCRT with a belly board under a prone position is superior to 3DCRT under a supine position, which could be a second choice for radiation of rectal cancer.

Application of the Humic Substances and Ammonia in Order to Minimize Losses on Nitrogen Fertilization

Nitrogen (N) is an element absorbed in larger quantities by plants due to the vast number of chemical and biological reactions. Despite the high nutritional need of this element by the plants, it is not a constituent of any terrestrial rock. To avoid high production costs of N, there is an increasing interest in the use of organic fertilizers in Brazil, including the use of humic substances (HS). In this work we evaluated the chelating properties of HS, when used together with a source of N. The nitrogen source used in this experiment was the ammonia. We checked the optimum conditions for interaction between the HS and ammonia such as: the ratio of reaction of each compound;minimum incorporation time between these compounds and the amount of ammonia that can be adsorbed by HS (income). The best ratio of ammonia/HS was 1/50 (v/v). Higher amounts of ammonia added to 50 mL of HS caused a greater loss of N. We also concluded that the application of ammonia/HS in the soil can be made immediately after their mixing, without the need of higher contact time between these substances in order to have the adsorption. No loss of ammonia was detected after 72 hours of its application together with HS. Finally, by using a factorial design, the best working area was found by settling the time of incorporation and volatilization in 24 h, and the volumes of HS and NH3 in 100 and 2 mL, respectively.

Benefits and Limitations of Volumetric Modulated Arc Therapy in Treating Bilateral Breast Cancer with Regional Lymph Nodes

Purpose: The study was performed comparing dosimetric characteristics of volumetric modulated arc therapy (VMAT) and field-in-field (FiF) techniques on a patient with synchronous bilateral breast carcinoma. Methods: The patients with bilateral breast cancer treatment were included in this study. A total dose of 40.05 Gy in 15 fractions was prescribed to the Planning Target Volume (PTV) of the whole bilateral breast cancer with the supraclavicular and infraclavicular nodes, with a complementary boost of 10 Gy in 4 fractions to the surgical bed (PTVboost). For both radiotherapy techniques, several VxGy parameters were analyzed for the PTVs, together with the Conformity index (CI), the Homogeneity index (HI) and the critical organs at risk (OARs), lungs and heart. Results: The patient was treated by the VMAT technique and the daily treatment time was less than 20 minutes with daily CBCT imaging. In the VMAT plan, the PTV 95% dose covered 38.89 ± 0.81 Gy, compared to 37.26 ± 1.02 Gy in the FiF technique. The VMAT plan improved the dose homogeneity index and lower dose in lung towards high dose region. Conclusion: The study demonstrates the viability of the VMAT technique in the treatment of bilateral breast cancer. The introduced single isocentric VMAT technique is fast to deliver and it increases the dose homogeneity of the target volume with some limitations. The treatment was well tolerated, without interruption of the treatment courses caused by treatment-related toxicities.

The Contribution of the Global Framework for Climate Services Adaptation Programme in Africa (GFCS APA) in National Adaptation Plan (NAP) Process for Tanzania

This article assesses the contribution of the Global Framework for Climate Services Adaptation Programme in Africa (GFCS APA) in the National Adaptation Plan (NAP) process for Tanzania. Different research project outputs (field survey and workshop reports) produced during the implementation of GFCS APA are reviewed to assess the contribution of GFCS APA programme in the establishment and implementation of NAP process in Tanzania. It is found that the implementation of GFCS-APA programme in Tanzania has improved the availability, accessibility, and applicability of climate information to different stakeholders. This has in turn attributed to significant use of climate information in planning and decision making in target sectors: agriculture and food security, disaster risk reduction, energy, health and water resource management. This has increased the adaptation capacity of vulnerable communities from the impacts of climate variability and change. Furthermore, it is evident that the aims and objectives of establishments of NAP process in Tanzania have been addressed through implementation of GFCS APA Programme. Moreover, since the GFCS APA in Tanzania is implemented within its five pillars namely: observation and monitoring, research, modeling and prediction, climate information systems, user interface platform and capacity development. The achievement made in each pillar contributed in enhancement of resilience of vulnerable communities to climate variability and change hence addressing the aims and objectives of NAP process in Tanzania. Therefore, it is recommended that achievements of GFCS APA Programme in Tanzania to be used as a guide to the development and implementations of the NAP process in Tanzania.
