The object of this study is to development digital textbook that is intuitⅣe and easy to provide a wide range of content and learning materials for Electric Circuit Unit in Elementary Science by Using iBooks Author. Digital textbook was developed first semester of fifth grade electrical circuit section 5 Sessions, analyzing the science curriculum and selecting the learning content through the previous research. Digital textbook was developed depending on the 5E learning cycle model that is effectⅣe in changing students preconceptions of scientific concepts. Authoring tool was used as iBooks Author and Bookry. Photos, Pictures, materials and videos used in textbook were taken directly or coⅡected without violate the copyright laws. Developed digital textbook was evaluated by criteria on digital textbook. As a results, developed digital textbook was helpful to understand the concept through a rich multimedia data and to enable the personalized experiment and to check thoughts and share the results with a high interest in digital dⅣice and variety of widgets. Digital textbooks was finaⅡy modified, supplemented and completed based on assessment. By iBooks Author, applying digital textbooks to class and students can be easily produced beyond the limits of textbook. And digital textbook can improve the satisfaction of learners for learning is expected to be.

The Dyeing processing, which can be a low-cost and easily application to production field was investigated by using some bathochromic agent and dyestuffs. The Δ L values and dye up-takes of threated several fabrics were investigated according to the dye concentration and pH of dyebath. The results were as follows : 1. The selection of bathochromic agent acts as important factor for improvment of bathochromic property of fabrics. 2. The pH of dyebath has a little effect on bathochromic effect. 3. In case of one bath treatment, the bathochromic agent has little effect on the improving bathochromic property of treated fabric. 4. The efficiency order of bathochromic effect is DTY + fila.> CVY > DTY and fabric structure is also effect on the bathochromic property of the polyester fabric.

In order to analysis of colour difference in dyeing process of the production field, several dyestuffs were selected for examine pH independance, step dyeing and migration test. And another investigation also carried out how much causes colour difference to insufficient washing process a t pre-treatment process. The results were as follows. 1. All used dyestuffes behavior showed high dye-up take a t the low pH condition. 2. In the examination of pH independence, C. I. Acid Red 57 and C. I. Acid Yellow 199 dyestuffs were exception behavior to used all dyestuffs. 3. By step dyeing results, mixed system of C. I. Acid blue 62 and C. I. Acid Red 57 have a good color reproducibility.
