A Study on the Hangul Representation Letter Styles

Hangul(한글) letter styles are made of 19 initial sounds, 21 medials of a Korean orthographic syllable, 27 final consonants. So it can be combined 11,172 letters. Even though we only use about 4,500 letters among 11,172, we must make all of these 11,172 letters in order to develop letters for KS font code. If we want to develop new Hangul letters, we must prepare some sample types before real works. In order to show some letters to users, it need to be decided types that representation letters. Because it is impassable that all letters are shown to users. In this case, short sentences are offered to show the types. But we don't know how exact informations the users can get from those sentences. Sample sentences shorted of letters information can give wrong letters information to users. The representation letters type have to have specific property like those. 1. They have to include maximum abundant information about characteristic type shape. 2. They have to be organized in order to be cognized type form and specific property. 3. The size of characters and the method of an array would be appropriate. This study will find the solution about first and second items above. And I'll use letter abstraction method using the diagonal line as a solution. Let's take an example about the abstraction of representation letters. In the a chart below, letters which are shown diagonally in the grey cells are decided as representation letters. If you want to verify the type ‘버’ shape, you can combine a vowel ‘ㅓ’ of ‘더’ on a vertical axis and a consonant ‘ㅂ’ of ‘베’ on a horizontal axis. The abstraction result of Hangul representation letters is as follows. The representation letters above can apply for type developing work. Especially during a process of developing type, because we may make letters for test with only the representation letters above, we can raise efficiency for development. But the representation letters above don't include some letters not used actually. So these letters are not proper for introduce sample letters which is become as goods. Among the representation letters, if the letters not used actually change with letters that can be applied or delete, the result is as follows. The representation letters which is shown above can be used for the representation letters which present Hangul letters become goods already.
