Study on inform ation service system for ocean d isa ster preven tion and reduction in Ta iwan Stra it ar ea

[摘要]：台湾海峡及其周边海域是我国海洋灾害发生的重点区域, 充分利用我国在该区域投入巨资 构建的海洋动力环境实时立体监测系统所获取的海洋动力参数数据, 构建区域性防灾减灾信息服务 系统具有重要的意义。从台湾海峡海洋动力环境立体监测数据防灾减灾应用和网络服务角度出发, 提出了防灾减灾信息服务的数据服务、信息服务和决策服务等3个层次的划分方法, 研究了基于数 据仓库、XML、中间件和基于地球球体模型的三维可视化等的服务技术实现策略。提出的防灾减灾 信息服务系统构建技术充分考虑了不同用户的应用需求, 并通过工程化实践提升了我国海洋动力环 境立体监测信息的广泛共享和深度应用的层次。[Abstract]:Taiwan Stra it and its c ircumjacent ocean region are main region of ocean disaster occurrence in Ch ina, so substantive fund has been devoted to construct ocean ic dynamic environment stereo rea l2timemon itoring system. Then the construction of information service system for oceanic d isaster prevention and reduction is of great impor2 tance tomak ing the best of the acqu ired data. In this paper, the service content partitionwas put forward firstly ac2 cord ing to the requirement of the ocean disaster prevention and reduction, which includes three aspects, .i e. data service, information service and decision2making service. The service realization technologieswere studied, wh ich includes datawarehouse, XML, middle2ware and three2dimensional visualization based on earth spheremode.l The technology system presented in th is paper upgraded the ocean dynamic environment stereomon itoring data sharing and its app lication level in Ch ina through meeting the requ irement of users and engineer ing app lication practice.国家高新技术研究发展计划( 863 计划)项目资助( 2009AA12Z208

国土资源信息交换体系建设模式分析与应用

国土资源信息蕴涵了多种数据类型和海量的数据,而且在日常管理和经营中还不断产生新的数据,为了更好地获取和利用国土资源信息,迫切需要解决国土资源管理部门定期更新或交换数据的任务,其中,空间数据是数据交换的重点和难点。本文介绍了在国土资源行业之间空间信息交换的总体思想,即在实现国家一级数据中心的基础上,由市地、省到国家级数据中心的数据逐级汇总和增量备份的方式,并进一步分析了国土资源信息交换体系的实现模式以及可采用的技术等方面内容,最后介绍了国土资源信息交换体系建设的实践

基于组件的服务器端共享地图符号库的研制

共享地图符号库是空间信息网络共享和交互式分析服务中的重要研究方向。本文以福建省3S应用综合服务平台、福建省政务信息共享平台中空间信息共享符号库建设为例,在分析基于GIS的地图符号库设计和实现技术基础上,结合多源空间信息网络共享、表达和分析服务的特点,提出一种面向网络综合服务应用的数字地图符号库的设计原理。基于GIS组件ArcObject开发一个分布于服务器端的共享地图符号库系统原型,并对其中的符号编辑、存储和管理的功能,以及符号化实施,作了详尽的叙述。该系统已集成于福建省政务信息共享平台服务代理系统上,初步实现了面向跨部门、跨行业网络共享和交互式分析的应用要求

基于Internet的元数据管理模式研究——以地理信息元数据管理为例

1 引言通讯和计算机技术的发展使信息成为国民经济和社会发展的重要资源,目前社会各个部门都在挖掘自己的信息资源整理和改善行业内部的数据库,在管理和应用这些海量信息的同时,一个突出的问题就是怎样有效地管理和组织海量的数据。元数据机制是解决上述问题的有效手段,随着各行业元数据标准的推出,行业内部海量数据的组织有了一定的规则。但是在基于这些规则的基础上怎样有效地实现海量数据的管理,这就为元数据的管理提出了更高的要求

False-Positive ¹²³I-Metaiodobenzylguanidine Scan in a Patient with Adrenocortical Cancer

A 59-year-old woman presented with a left adrenal tumor 4 cm in diameter. The ¹²³I-metaiodobenzylguanidine (MIBG) scintigraphy showed apparent accumulation in the left adrenal tumor. However, the patient had no sign or symptoms suggesting pheochromocytoma. No biochemical evidence of catecholamine excess was noticed. Computed tomography (CT) revealed relatively strong enhancement in the arterial phase, which persisted until the portal phase. The computed tomography (CT) and magnetic resonance imaging showed 2 liver nodule suspected to be metastatic tumors. No ¹²³I-MIBG accumulation was seen in these nodules. CT also showed thyroid nodules with calcification, which suggested papillary thyroid cancer. Based on the findings, open left adrenalectomy, partial hepatectomy and segmentectomy were performed under the clinical diagnosis of pheochromocytoma and metastatic liver tumors. Histopathological diagnosis was adrenocortical cancer. There was only lymphocyte infiltration in the liver nodules. Postoperative recovery was uneventful, and the patient underwent partial thyroidectomy 6 months later. The pathological diagnosis was papillary thyroid cancer. She has been without recurrence or metastases for 18 months after adrenalectomy. We found only 6 cases of MIBG scintigraphy-positive adrenocortical cancer in the literature. The mechanisms for MIBG uptake in adrenocortical cancer are discussed with a review of the literature

養老断層のP波浅層反射法地震探査 : 2004年志津測線

We present new, high-resolution seismic reflection data (2004 Shizu profile) acquired across the forelimb of the Yoro basement-involved fold to further image its subsurface geometry. A seismic source (mini-vibrator) and 180-channel digital telemetry recording system were used in an off-end configuration with the nearest receiver adjacent to the source to record seismic waves from deeper reflection points. A 10-m source and geophone spacing give a 5-m CMP (common midpoint) spacing on the final section. The nominal CMP stacking fold had 90 traces. We also suppressed coherent noise by repeating source points 7-10 times. After data processing including surface-consistent statics, velocity analysis, normal moveout (NMO) correction, residual statics, CMP stack, and migration, the section was finally depth-converted using of stacking velocities. Reflectors imaged on the seismic profile illuminate growth strata on the forelimb of the Yoro basement-involved fold, providing insights into the kinematic solution of the underlying active thrust
