Là đơn vị tiên phong xây dựng cơ sở dữ liệu địa chính từ năm 2006, nên cấu trúc cơ sở dữ liệu địa chính của Quận 6-TP.HCM hiện không phù hợp với quy chuẩn hiện hành theo thông tư 75/2015/TT-BTNMT và không đồng bộ với cấu trúc dữ liệu địa chính của các địa phương khác. Điều này gây nhiều khó khăn trong vận hành cơ sở dữ liệu địa chính, đặc biệt trong đồng bộ cơ sở dữ liệu các cấp. Với nhiều phương pháp, nghiên cứu đã (1) phân tích khác biệt về cấu trúc dữ liệu địa chính cũ theo Thông tư 17/2010/TT-BTNMT với cấu trúc mới theo Thông tư 75/2015/TT-BTNMT; (2) xây dựng bộ cấu trúc dữ liệu thuộc tính địa chính mới trên Microsoft SQL Server; (3) ứng dụng C#.Net xây dựng công cụ chuyển đổi cấu trúc dữ liệu thuộc tính địa chính; (4) chuyển đổi thành công cơ sở dữ liệu thuộc tính địa chính của Phường 9 (với 12.196 bản ghi) sang cấu trúc mới một cách đầy đủ, chính xác, nhanh chóng và hoàn toàn tự động. Kết quả đạt được giúp tiết kiệm thời gian, kinh phí và nhân lực trong quá trình chuyển đổi dữ liệu nhưng vẫn đảm bảo độ chính xác và toàn vẹn cho cơ sở dữ liệu địa chính. Đây là tiền đề thuận lợi để đồng bộ hóa dữ liệu địa chính các cấp, góp phần hoàn thiện cơ sở dữ liệu đất đai quốc gia và phù hợp với chiến lược của ngành về tăng cường năng lực quản lý Tài nguyên và Môi trường trong thời gian tới. ABSTRACTAs one of the first units which built cadastral databases since 2006, the structure of cadastral database of District 6 - HCMC is not suitable for the current regulation at Circular No. 75/2015/TT-BTNMT as well as does not synchronize with the database structure of other localities. This caused many difficulties in operating and sharing cadastral database, especially in the process of synchronizing cadastral databases at all levels. With many methods, the study has achieved these results such as: (1) Analyzing the differences in cadastral data structures between Circular 17/2010/TT-BTNMT and Circular 75/2015/TT-BTNMT; (2) Using Microsoft SQL Server Database Management System to create the new structure of cadastral attribute database for District 6; (3) Using C#.Net programming language in building the tool to convert the structure of cadastral attribute data; (4) Successfully testing in converting this database for one ward of District 6 (case study in Ward 9) from existing structure to the new one; and this whole process was carried out fully, accurately, easily, quickly and completely automatically. Those results helped save time, money and human resources in converting data but ensure the accuracy and integrity of the cadastral database. This is a favorable premise for the process of synchronizing cadastral data structure at all levels, contributing to complete the national centralized land database, in line with MONRE's strategy in strengthening the capacity of natural resources and environmental management of Vietnam in the near future.

In planning approval field, AutoCAD data format is used widely, for it is convenient to map.However, for massive planning approval data, it is difficult to query the corresponding spatial and attribute characteristics by AutoCAD files. While ArcSDE can unifiedly manange spatial and attribute data, whose strong database management is inherited from relational database. To address planning approval field interoperation problem between AutoCAD and ArcSDE in planning approval data management system, we took redevelopment from AutoCAD to ArcSDE database based on C#.Net and Object SDK. The data could be operated by Down-Load and Up-Load module in the system. Down-Load module was developed to load planning data from ArcSDE to AutoCAD, Up-Load module was to store AutoCAD format data into ArcSDE.As a case study,the modules were integrated into the Planning Approval Data Management System for Yueyang city and the data interoperation was very fast and easy between AutoCAD and ArcSDE+SQL Server 2008. The results show that the implemented interoperation function is convenient for planning approval data management.

This paper demonstrates the statistical approach for describing failures and lifetimes of water mains. The statistical approach is based on pipe inventory data and the maintenance data registered in the data base. The approach consists of data pre-processing and statistical analysis. Two classes of statistical models are applied, namely counting process models and lifetime models. With lifetime models, one can estimate the probability which a pipe will fail within a time horizon. With counting process models one can see the deteriorating (or improving) trend in time of a group of “identical” pipes and their rates of occurrence of failure (ROCOF). The case study with the data base from Trondheim municipality (Norway) demonstrates the applicability of the statistical approach and leads to the following results: 1). In the past 20 years, Trondheim municipality has experienced approximately 250 to 300 failures per year. However, the number of failures per year will significantly increase in the near future unless better maintenance practice is implemented now. 2). Unprotected ductile iron pipes have a higher probability of failures than other materials. The average lifetime of unprotected ductile iron pipes is approximately 30 to 40 years shorter than the lifetime of a cast iron pipe. 3). Pipes installed 1963 and 1975 are most likely to fail in the future; 4) The age of a pipe does not play a significant role for the remaining lifetime of the pipe; 5). After 2 to 3 failures, a pipe enters a fast-failure stage (i.e., frequent multiple between failures).

AbstractMost cities in the United States rely on zoning to address important planning-related issues within their jurisdictions. Planners often use GIS tools to analyze these issues in a spatial context. ESRI’s ArcGIS Urban software seeks to provide the planning profession with a GIS-based solution for various challenges, including zoning’s impacts on the built environment and housing capacity.This research explores the use of ArcGIS Urban for assessing the existing zoning and comprehensive plans in meeting the projected residential growth in the near future using the City of Arlington, Texas as a case study. The exploration provides examples and lessons for how ArcGIS Urban might be used by planners to accomplish their tasks and highlights the capabilities and limitations of ArcGIS Urban in its current stand. The paper is concluded with some suggestions for future studies.

Global And Local

In this research, a hybrid approach for path planning of autonomous ships that generates both global and local paths, respectively, is proposed. The global path is obtained via an improved artificial potential field (APF) method, which makes up for the shortcoming that the typical APF method easily falls into a local minimum. A modified velocity obstacle (VO) method that incorporates the closest point of approach (CPA) model and the International Regulations for Preventing Collisions at Sea (COLREGS), based on the typical VO method, can be used to get the local path. The contribution of this research is two-fold: (1) improvement of the typical APF and VO methods, making up for previous shortcomings, and integrated COLREGS rules and good seamanship, making the paths obtained more in line with navigation practice; (2) the research included global and local path planning, considering both the safety and maneuverability of the ship in the process of avoiding collision, and studied the whole process of avoiding collision in a relatively entirely way. A case study was then conducted to test the proposed approach in different situations. The results indicate that the proposed approach can find both global and local paths to avoid the target ship.

The current study explores the multifaceted and entwined structure of constraints and spaces of the possibilities of moving ahead among the Dooms of Jammu, India, where the possibilities of upward mobility through education as a means have been observed. Interviews and detailed case study were done with eight cases. Four overlapping super-ordinate themes developed during the course of study: (a) challenges of different generation learners, (b) lack of different forms of capital, (c) dis-identification from own and emulating others and (d) mushrooming of hybrid and mimic generation. The participants experienced the very process of change and continuity through education in their lives. It is observed that education helped in converting the morphology of their existing structure. Each of the interviewee has some exclusive experiences to share, offering significant insights into their lives, struggles and their conditions. The results indicate that the first-generation learners have to face many obstacles. The study concludes that education gives better results under certain circumstances. The chances of low caste children performing better are higher if the educational institutions run with mixed batches with students belonging to all the sections of the society.

The case-study of a steel bowstring bridge set in a marine environment and highly damaged by corrosion is presented. The bridge was built in 2004 and was repainted for corrosion protection in 2010. Despite the recent construction and the maintenance interventions, many structural elements like hangers are highly damaged by corrosion with decreasing performance in terms of serviceability and ultimate limit states. A deep investigation was carried out in order to assess the bridge and to establish the necessary retrofit actions to be carried out in the near future. In-situ tests reveal the reduced performance of the original steel in terms of strength and corrosion protection, together with the inefficiency of the successive maintenance interventions. The paper presents assessment of the bridge and retrofit measures, including replacement of the hangers and galvanization through thermal spray coating technology, in order to increase its service life. The results of the investigations and the intervention measures are outlined and discussed.
