This study was performed to compare Surepath$^{TM}$ liquid-based smear and a conventional cervicovaginal smear with reference to a histological diagnosis. A hybrid capture test (HCII) was also performed and analyzed. We collected matched cases for cervicovaginal cytology-histology: 207 cases for conventional cytology (CC) and 199 cases for liquid-based cytology (LBC). HCII was performed in 254 patients. When a cytological diagnosis of ASCUS or above (ASCUS+) is classified as positive and a histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for LBC was 91.7% and 75.9%, respectively and the sensitivity and specificity for CC was 62.6% and 96.1%, respectively. When a cytological and histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for LBC was 77.5 and 96.6%, respectively and the sensitivity and specificity for CC was 49.7% and 100%, respectively. When a histological diagnosis of LSIL+ is classified as positive, the sensitivity and specificity for HCII was 78.9% and 78.1%, respectively. The concordance ratio between the cytological and histological diagnosis was 80.4% (kappa=76.0) for LBC and 56.5% (kappa=55.1) for CC. LBC is more sensitive and less specific then CC, as a cytological cutoff level of ASCUS, but more sensitive and equally specific, as a cytological cutoff level LSIL or HSIL. LBC is more reliable with a high concordance ratio between the cytological and histological diagnosis.

This study was conducted to investigate the effect of atmosphere-leaf vapor pressure deficit (VPD) in Heracleum moellendorffii and Aruncus dioicus var. kamtschaticus. The VPD was rapidly increased with increasing temperature and decreasing relative humidity. Taken as a whole, the stomatal transpiration reaction was slightly late with increasing of VPD. Maximum photosynthetic rate at high-VPD condition was 6.49 µmol CO<sub>2</sub>·m<sup>-2</sup>·s<sup>-1</sup> in Heracleum moellendorffii Hance, which was a little lower than 5.57 µmol CO<sub>2</sub>·m<sup>-2</sup>·s<sup>-1</sup> in Aruncus dioicus var. kamtschaticus, respectively. After 2 p.m, stomatal transpiration of Heracleum moellendorffii at the high VPD condition was rapidly decreased. The results indicated that physiological activities in Heracleum moellendorffii are more limited from high VPD conditions.

This study was carried out to establish a proper cultivation site and to diagnose the drought tolerance of Oplopanax elatus leaves by using pressure-volume curves. As a result of analysing data measured, the leaf of Oplopanax elatus showed the osmotic pressure at full turgor(Ψosat) was -0.77 MPa, and the osmotic pressure at incipient plasmolysis(Ψotlp) was -0.90 MPa. Then, the value of maximum bulk modulus of elasticity Emax was 3.7 MPa, showing that slightly lower drought tolerance of Oplopanax elatus. Furthermore, the values of relative water contents RWCtlp and RWC<sup>*</sup> were above 80%, showing that the function of osmoregulation is somewhat better. Thus, responses to water relations such as Ψosat, Ψotlp, Emax, RWCtlp and RWC<sup>*</sup> of Oplopanax elatus showed relatively lower drought-tolerance property indicating that those growth are appropriate in high moisture soil sites.

This study was conducted to investigate of growth performances and net assimilation rate(NAR) of Allium microdictyon Prokh. distributed inland and Allium ochotense Prokh. originated Ulleung-do. The Allium microdictyon on the growth of 1-2 years showed the largest relative growth rate, and showed high relative growth from three to four years. Allium ochotense on the growth from one year to three years showed high relative growth rate. The T/R rate of Allium ochotense of 2~5years was in the range of 0.4~0.5. However, The T/R rate of Allium microdictyon was increased as increasing with age. This implies that Allium microdictyon was consumed more energy on growing subterranean part. The LWR of 1~3years old Allium ochotense. was showed more smaller than 4~5years old. It seems that the growth characteristics of Allium ochotense 1-3 years after sowing the leaf growth consume more energy than Allium microdictyon. Net assimilation rate(NAR) of Allium ochotense for 1-3 years after sowing was higher than that of Allium microdictyon. In this time, the material of Allium ochotense has a higher production efficiency can be seen indirectly.

This study was carried out to establish a proper cultivation site and to diagnose the drought tolerance of Heracleum moellendorffii leaves by using pressure-volume curves. As a result of analysing data measured, the leaf of H. moellendorffii showed the osmotic pressure at full turgor (Ψ<sub>o</sub><sup>sat</sup>) was -1.0MPa, and that at incipient plasmolysis (Ψ<sub>o</sub><sup>tlp</sup>) -1.2MPa. Then, the value of maximum bulk modulus of elasticity Emax was 28MPa, showing the sightly strong drought tolerance of H. moellendorffii. Furthermore, the values of relative water contents RWC<sup>tlp</sup> and RWC<sup>*</sup> were above 88%, showing that the function of osmoregulation is somewhat better. Thus, responses to water relations such as Ψ<sub>o</sub><sup>sat</sup>, Ψ<sub>o</sub><sup>tlp</sup>, E<sub>max</sub>, RWC<sup>tlp</sup> and RWC<sup>*</sup> of H. moellendorffii showed it's slightly high drought tolerance property.

This study was conducted to investigate the photosystem II activities of Cercis chinensis by soil water condition. Drought stress was induced by withholding water and waterlogging treatments was immerging the pots for 15 days. Results showed that the relative activities per reaction center such as ABS/RC, TRo/RC and Dio/RC were significantly increased compared with the control group after 12 days in waterlogging treatments. Particularly, Dio/RC increased substantially under waterlogging stress, indicating that excessive energy was consumed by heat dissipation. Furthermore, the performance index on absorption basis(PI<sub>abs</sub>) and responses to structural and functional PS II(SFI<sub>abs</sub>) were dramatically decreased after 15 days in both the drought and waterlogging treatments, which reflects the relative reduction state of the photosystem II. These results of chlorophyll a fluorescence by OKJIP analysis show that the sensitive changes photosystem II activity. Thus, on the basis of our results that Cercis chinensis was exhibited a strong reduction of photosynthetic activity to waterlogging stress, and OKJIP parameters such as ABS/RC, DIo/RC, PI<sub>abs</sub> and SFI<sub>abs</sub> could be useful indicator to monitor the physiological states of Cercis chinensis under soil water condition.
