Kinetic Typography Rendering Engine contains Primitive Motion Library to convey the emotions. It wraps essential elements such as time, space and speed to express movement. Scrutinized primary movement is constituted as Primitive Motion Library and it is a way to kinetic typography properly. The main purpose of Primitive Motion Library substitutes the existing method to manufacture kinetic typography; such as using software and doing expert coding. To achieve this purpose, the thesis is separating the movement, classifying it systematically and developing Primitive Motion API which renders Kinetic typography.

The kinetic typography animates the static text and it will enable the delivery the opinion and emotion, but we should use professional software or do complex coding precess to create a motion into an existing static text. In this paper, we propose the primitive motion API which is the way to configure the kinetic typography easily by adding a motion into the static text. In the pursuit of this purpose, we analyzed the movement of the text, defined the underlying levels of the movement and designed the primitive motion API to express the kinetic typography promptly. Furthermore, we verified the performance of the primitive motion API by testing the usability. Using the primitive motion API to implement the kinetic typography explicitly might substitute for tedious coding process and usage of the existing professional software so it makes anyone be able to apply the kinetic typography in a variety of applications.

The effects of laser welding beam quality is very large. However, not an analysing case was found forthe difference on the plasma emission signal during laser welding according to the beam quality. Therefore,in this study, we compared and evaluated penetration and signal change according to the beam quality atthe a similar wavelength band by using a fiber laser and Nd:YAG laser. In addition, we took high speedvideography in order to make sure that FFT analysis reflects the actual motion period of keyhole andfound the period of video analysis and FFT mostly matched. As a result, it is expected to secure higherreliability than evaluating signal intensity when appling FFT to monitoring.
