This paper deals with the effect of dynamic contents to congnition ability of young lower grade students in universities. It is found that the subjects for MCT (Mental Cutting Test) are trained and definitely affected by some dynamic contents communicated before the test. The reason and the validity are discussed here.
The development of tutorial contents for Graphic Science education is shown by adopting 3 D Applets. While Graphic Science is based on drawing geometry, it is still essential for the improvement in space cognition ability about solid geometry. These contents are expected and aim to bring immediate results on the progress.

In this thesis, to construct an interface that displays similar images in the screen space by using some impression words, the possibility of classification of similar image group is described.
First the agreement of the similar image groups classified by subjective judgment of evaluator (subjective similar image group) and the groups classified with statistical method using impression degree (impression degree similar image group) was examined. Next to decide the user model the agreement of the impression degree between evaluators and the agreement of the images of the subjective similar image group were examined.
Twenty-one kinds of color images were chosen to classify the similar image groups and nine kinds of impression words were chosen.
An image classification system was developed to construct the similar image groups and to examine the impression degree of the images.
Thirty-five evaluators input their impression degree of each image with the system, and then those images were classified to the similar image groups. The results of obtaining are shown below.
(1) Because the agreement of the subjective similar image group and the impression degree similar image group was a range from 52 to 86%, a high agreement was proven.
(2) The main high correlation impression words among the evaluators were‘feminine’, ‘delicate’and ‘cheerful’and raw correlation words were‘simple’and‘retro’.
(3) The similarities of the evaluators were calculated by the principal co-ordinate analysis. As a result, 86% of the evaluators showed the same tendency.
Therefore, it was clarified that the classification of the similar image group using the impression words is possible, and the user model can cover a lot of users by constructing the representative model.

By taking up“KOBE HL PROJECT”, one of the mega shopping center in 1992, we consider the design process of composing the architectural shape, not only by concerning study models, plans, perspective views on the initial stage of planning, but also by tracing back the process of the appearance of terms classified orderly on time based on every document described after design meeting. In the result,
(1) The designer has a tendency to seek many conceptual terms from all quarter not to fix special terms which are appearing and soon disappearing on every design meeting
(2) The designer uses a few morphological terms appearing frequently on the initial stage of planning, and this tendency is the same between on the initial stage of planning and on the final stage of completion of building.
(3) A half of morphological terms are kept in designers consideration on the final stage of completion. The basic image of architectural shape is called to mind and recognized on the initial stage of planning
(4) The initial stage of planning is classified into 4 stages, (A) clay models for examining the outline of building volume not using drawings, (B) pasteboard models for examining site plan and space design by freehand drawings, (C) forming-block models for understanding the appearance of building facades attached elevations on their surfaces by measuring drawings, (D) design-board models for clarifying the inner spaces by increasing the scale of model. It is clarified that the architectural shape of building is growing up little by little to the concrete shape according to the progress of design.
