整合Blackboard的资源管理平台的开发研究

目前普通高等教育和基础教育都建有比较完善的数字化教学资源和相应的资源管理平台,但可与Blackboard在线教学系统整合的资源平台还很少见。为此,在立足本校实际情况,依照LOM元数据规范,设计数字化教学资源管理平台的系统框架与功能。该平台不仅具有资源管理功能,并能与Blackboard在线教学系统和图书资源目录实现整合。     

Business intelligence approach to supporting strategy-making of ISP service management

The recent deregulation of telecommunication industry by the Taiwanese government has brought about the acute competition for Internet Service Providers (ISP). Taiwan’s ISP industry is characterized by the heavy pressure for raising revenue after hefty capital investments of last decade and the lack of knowledge to develop competitive strategies. To attract subscribers, all ISP dealers are making an all-out effort to improve their service management. This study proposes a Business Intelligence process for ISP dealers in Taiwan to assist management in developing effective service management strategies. We explore the customers’ usage characteristics and preference knowledge through applying the attribute-oriented induction (AOI) method on IP traffic data of users. Using the self-organizing map (SOM) method, we are able to divide customers into clusters with different usage behavior patterns. We then apply RFM modeling to calibrate customers’ value of each cluster, which will enable the management to develop direct and effective marketing strategies. For network resource management, this research mines the facility utilization over various administrative districts of the region, which could assist management in planning for effective network facilities investment. With actual data from one major ISP, we develop a BI decision support system with visual presentation, which is well received by its management staff.     

企业内网安全的重要性和管理措施

近年来,在所有的网络安全事件中,有超过70%的安全事件是发生在内网上的,并且随着网络的庞大化和复杂化,这一比例仍有增长的趋势。因此内网安全一直是网络安全建设关注的重点,但是由于内网以纯二层交换环境为主、节点数量多、分布复杂、终端用户安全应用水平参差不齐等原因,一直以来也都是安全建设的难点。

Integrating scientific modeling and supporting dynamic hazard management with a GeoAgent-based representation of human–environment interactions: A drought example in Central Pennsylvania, USA

Recent natural disasters indicate that modern technologies for environmental monitoring, modeling, and forecasting are not well integrated with cross-level social responses in many hazard-management systems. This research addresses this problem through a Java-based multi-agent prototype system, GeoAgent-based Knowledge System (GeoAgentKS). This system allows: (1) computer representation of institutional regulations and behavioral rules used by multiple social institutions and individuals in cross-level human–environment interactions, (2) integration of this representation with scientific modeling of dynamic hazard development, and (3) application of automated reasoning that suggests to users the appropriate actions for supporting cooperative social responses. This paper demonstrates the software architecture of GeoAgentKS and presents such an integrated approach by modeling the drought management processes in Central Pennsylvania, USA. The results show that it is possible to use GeoAgentKS to represent multilevel human–environment interactions and to use those interactions as input to decision making in hazard management.     

从社会管理角度来看设计——在现代设计史里去找答案

长期以来,有很多学者都对设计做了很多重要的研究,并得到了丰富的理论成果。但是设计是一个很难说得明明白白的词,其内在的含义却需要不断的挖掘,如其内在所含的管理属性就需要我们去做一个探究,本文从历史的、客观的角度对设计的管理层面进行了探讨。     

基于水印和密码的数字版权管理模型的研究

在分析了数字版权研究现状和功能框架的基础上,设计了基于多重数字水印和密码的版权管理模型;该模型采用数字内容和许可证各自单独封装、独立分发的方式,使得只有购买了许可证的特定用户才能使用数字内容,实现了水印作品的许可交易;另外,内容服务器采用的对数字作品加载两次水印,对数字内容部分签名加密,未加密部分签名的方案,在有效保证数字内容安全传输的基础上又减少了计算量和存储量;分析表明该模型有显著的优点和很好的安全性。
