96 Methods: We assessed the value of the TNR in the SCTs classified by an integrated diagnostic model. Included in the study were 1,346 individuals (701 males, 645 females) who participated in the Korean Genome and Epidemiology Study (KoGES). The TNR was measured by active anterior rhinomanometry (AAR) at transnasal pressures of 100 and 150 Pascal (Pa). Results: The average TNR was 0.186 ± 0.004 Pa/cm3/second at 100 Pa in the Tae-eum (TE), 0.193 ± 0.007 in the So-eum (SE), and 0.208 ± 0.005 in

Higher values of TNR were more likely to be reported in the SY type at 100 Pa and 150 Pa. In the stratified analysis by sex, the SY type in males and females tended to have higher TNR value than the TE and SE types at transnasal pressure of both 100 Pa and 150 Pa. Conclusion: These results provide new approaches to understand the functional characteristics among the SCTs in terms of nasal physiology. Further studies are required to clarify contributing factors for such a difference. Contact: Dae Wui Yoon, 9286392a@hanmail.net http://dx. Purpose: Many studies have addressed the hypothesis proposed by the visceral theory in Sasang constitutional medicine that specific types of Sasang constitution have a different functional activity of the internal organs, and have tried to confirm the theory using modern scientific methods. Since few studies have evaluated the activity of the lung, we investigated whether there is a difference in the lung function according to the Sasang constitutional types (SCTs) by means of the pulmonary function test (PFT). Methods: A total of 1,320 individuals who participated in the Korean Genome and Epidemiology Study and completed the PFT were included. SCTs were classified by an integrated diagnostic model. We determined the values of the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC (%) in the SCTs. Participants who had pulmonary disease were excluded from the analysis based on the chest X-ray examination. Results: The Tae-eum (TE) type had significantly lower FVC than the So-eum and So-yang types (P = .0272) after adjusting for confounding factors including age, sex, weight, height, and smoking status. FEV1 did not differ among the SCTs (P = .619). In the analysis stratified by gender, males of the TE type had the highest FEV1/FVC (P = .0401), whereas FVC was the lowest in females of the TE type among the SCTs (P = .0079). Conclusion: These results support the hypothesis that TE type has hypoactive lungs, in terms of the lung volume. Contact: Seung Ku Lee,
