There were lots of changes of the wooden structure in the middle of Joseon Dynasty. It was the time of replacement from Jusimpo (simple bracket system) to Ikgong (wing-like bracket system) and each bracket had shown mutual variation as well as itself. The aspects of change were discovered that the decorative elements of Ikgong and Dapo (multi-bracket system) had accepted from each other. It was clearly shown that not only the Ungung (carved cloud-shape) and Chotgaji (shape of the acuminate leaf) of Ikgong had affected to Dapo, but also Gaang (pseudo-pointing cantilever) of Dapo had affected to Ikgong. It was mostly found in the Buddhist architecture because there was the conservatization of ruling hierarchy as well as the active growth of Buddhist society.

A violin plays an essential role among string instruments. It has an extremely strong expressive power that can be conveyed through beautiful timbre when played correctly. However, a beginner who attempts to play the violin will be most likely to face difficulties in placing his or her fingers on a specific point of the fingerboard or in bowing the violin on a specific string. In order to resolve this difficulty, the database of a professional violinist's bowing skills were inserted beforehand. By doing so, a beginner can emulate professional's violin by comparing his playing with the constructed database that is programmed in the computer. Accordingly, the results are displayed on the monitor after being evaluated by the performance evaluation function using a fuzzy logic.
