This study is a follow-up study of Han and Kang (2013) and Kang and Han (2013) which examined cross-generational changes in the Korean vowels /o/ and /u/ using acoustic analyses of the vowel formants of these two vowels, their Euclidean distances and the overlap fraction values generated in SOAM 2D (Wassink, 2006). Their results showed an on-going approximation of /o/ and /u/, more evident in female speakers and non-initial vowels. However, these studies employed non-words in a frame sentence. To see the extent to which these two vowels are merged in real words in spontaneous speech, we conducted an acoustic analysis of the formants of /o/ and /u/ produced by two age groups of female speakers while reading a letter sample. The results demonstrate that 1) the younger speakers employed mostly F2 but not F1 differences in the production of /o/ and /u/; 2) the Euclidean distance of these two vowels was shorter in non-initial than initial position, but there was no difference in Euclidean distance between the two age groups (20's vs. 40-50's); 3) overall, /o/ and /u/ were more overlapped in non-initial than initial position, but in non-initial position, younger speakers showed more congested distribution of the vowels than in older speakers.

This study aims to understand the architectural characteristics and living pattern of the Daor and to make a comparative study with the Han race. This research inquired into the background of the Daor and surveyed the present condition of traditional houses. As a result of this study, the features of Daor's traditional house is synthesized as follows. 1) The arrangement of village is in a row facing south. The site plan and exterior shape is like as the Manchurian race. 2) Making west window and creating a bright atmosphere is the unique architectural style. 3) Viewed from spatial layout and function, Daor's has more remarkable difference from Han's. That is to say, the room equipped with Kang is daily space and kitchen is just space for cooking in contrast with the Han.
