In this research, the SOLO (Structure of the Observed Learning Outcome) Taxonomy presented by Australian scholars Biggs and Collis (1982) was adopted, and students studying the fifth and sixth grades in Taipei area were chosen as research targets.This study was primarily implemented with a quantitative analysis and supported by a qualitative analysis. In order to carry out the research, a questionnaire had been designed with criteria suggested by Jones et al.(2000), including "describing data","organizing and reducing data","representing data" and "analyzing and interpreting data." This questionnaire consisted of open-ended questions, and after analyzed with qualitative methods, the responses were classified and scored based on standards set in SOLO Taxonomy. Then the quantitative method "Partial Credit Analysis" from Rasch model was adopted in examining the reliability, validity and consistency of outcomes from the qualitative analysis.

提出的统计思维架构－「描述资料」、「组织及简化资料」、「呈现资料」、「分析资料」作为评量试题的向度，题型为开放性问答题，在区分学童的答题表现方面，采用质的分析，参照SOLO（Structure of the Observed Learning Outcome）分类法的分类标准，将学童不同的答题反应进行分类，给予不同的分数，最后再采用Rasch model中的部份给分模式进行量化分析，以量化数据佐证质性分析的信度与效度，以及不同给分的吻合度。

However, due to the immense data, heterostructure and multiplicity of data types, complicated data structures in databases are available in the real world, those have made association rule mining face a lot of challenges, therefore, the complete concept lattice model is introduced to the study of association rule mining in the dissertation, and some studies are made on concept lattice model, algorithms, and data reduction etc.

然而，由于现实世界数据的海量、异构和数据类型的多样性、结构的复杂性等特点，对关联规则挖掘的研究提出了新的课题。本文将具有完备特性的概念格模型引入到关联规则挖掘的研究，针对关联规则挖掘的模型、方法以及数据归约等方面开展了研究，主要内容及创新工作如下：1。

Cotton bollworm is more serious pest in cotton belt of Xinjiang, China. In order to guarantee the biggest commercial cotton belt sustaining and healthy, Information project of pest monitoring and prediction is carried out in this commercial cotton base. In this research, we are focusing on automatical data acquisition, data delivery, design and construction of database, data processing and data display and forecast based on GIS. Key technologies and difficulty are explored, which is built the manipulable technologies and management platform for regional monitoring and prediction of cotton bollworm.

棉铃虫在新疆棉区危害逐年加重，为保障我国最大商品棉基地的可持续发展，开展了优质棉基地植保信息工程研究，本文结合新疆植保体系发展和未来新技术的动向，重点集中在有害生物数据自动化采集、数据远距离传输、数据库设计和数据库建设、模型处理和GIS系统在预测和信息发布上的应用，探索植保信息工程建设中的难点和关键技术，为区域化棉铃虫监测和预警提供技术保障和管理平台。

Work in this paper focuses on the data mining from chromatographic retention index data. A retention index database that contains about 50000 records of retention index is firstly established. Projection pursuit technique is then utilized to do data mining upon the data in order to find out some valuable information about the relationship between the retention indices and structural descriptors. A novel algorithm for projection pursuit is developed in this work. Samples of alkane, alkene and cycloalkane are investigated.
