Their learning processes and attitudes toward such innovation in their community were also examined. Thirty juveniles, 13-18 years of age in each Hangdong and Maerim districts, Chiang Mai province were employed in the study. Data collections were made through questionnaires, interview, test, group discussion and brainstorming. Analysis and evaluation were carried out with the applications of sufficient economy philosophy, constructivism theory and Torrance＇s future problem-solving instructional model. Results showed that the learning innovation of hyper-multimedia presented by the use of animation, video, scene and sound with related action script synchronization was considerably effective. With the application of sufficient economy philosophy, the result indicated that performance efficiency （El/E2） was 92.228/9.83 and the adolescents learning processes and attitudes were very good. These included purchasing of moderate ICT equipments, information screening for self-immunity and creative using of internet and ICT morally and ethically according to the computer laws. This independent learning system was properly designed for the juveniles with the right to retrieve the data or stop using at anytime. By using Torrance＇s approach and constructivism theory emphasizing on brainstorming techniques, it was noted that learning process was very well adopted by the adolescents with high satisfaction. They had good attitudes toward the extension of sufficient ICT cultural using in their community with emphasis on brotherly relationship. Related organizations should educate their parents to instruct the juveniles to use the internet properly and encourage people to be aware of ICT business in order to protect social and cultural problems encountered in the future.展开更多

文摘为了有效地实现多媒体地理信息系统 ( multimediageographic information system,MGIS)数据的存储和管理 ,必须设计有效的数据模型。但现有的几种多媒体数据模型( NF2模型、面向对象模型和超媒体模型等 )尚不能满足MGIS数据管理的要求。为此 ,深入分析了现有几种多媒体数据模型的优缺点及其相互关系 ,提出了一种新的、集现有几种多媒体数据模型优点于一体的多媒体数据组织和管理模型 ,即基于对象关系的超媒体数据模型 ( hyper-mediadata model based on object-relation,O-RHDM) ,论述了 O-RHDM的原理和方法 ,并给出了该模型的规范化描述和操作运算的数学定义。
