The purpose of this study is to find out why Whitney Houston gave healing to people around the world based on Shin Jae-hyo's gwangdaeron (clown theory). In Korean music, gwangdae (廣大, the title of clown) is a nickname dedicated to outstanding artists. Not only is it a clown that cannot be a person, but it does not give a clown a nickname for doing art activities. This is why Shin Jae-hyo, a pansori (Pansori epic chant) theorist and critic in the late 19th century of the Joseon Dynasty, presented the virtues of outstanding artists. There are four outstanding clown conditions claimed by Shin Jae-hyo: appearance (人物), words (辭說), perfect vocal music (得音) and wonderful movements (neoreumsae). These conditions show how difficult it is to be a gwangdae (a prominent artist), or an accomplished artist. We think Whitney Houston is a famous singer who fits these conditions. In her heyday, she was optimized for Shin Jae-hyo's clown theory, while her post-2007 moves are regrettable. However, it is clear that he is a singer who fits well with the title of America's greatest clown. In conclusion, I felt that the best emotion through music was the best healing, and that the best singer was becoming the best healer.

Purpose : The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. Materials and Methods : Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam computed tomography (CBCT) images taken before (T1) and after (T2) maxillary expansion therapy with a banded Hyrax appliance. Multiplanar slices were used to measure linear dimensions and palatal vault angle. Volumetric analysis was used to measure maxillary sinus volumes. Student t tests were used to compare the pre- and post-treatment measurements. Additionally, differences between two age groups were compared with Mann-Whitney U test. The level of significance was set at p=0.05. Results : Comparison of pre-treatment to post-treatment variables revealed significant changes in the transverse dimension related to both maxillary skeletal and dental structures and palatal vault angle, resulting in a widened palatal vault (p<0.05). Hard palate showed no significant movement in the vertical and anteroposterior planes. Nasal cavity width increased on a mean value of 0.93mm(SD=0.23, p<0.05). Maxillary sinus volume remained virtually stable. No significant age differences were observed in the sample. Conclusion : Hyrax expansion therapy did not have a significant impact on maxillary sinus volume.
