  • Stem firmness and flowering response of cut lily as influenced by medium composition (Control: Upland soil, Pt: Peatmoss, Pe: Perlite, Ve: Vermiculite, Rrh: Rotted rice-hull, RPt: Russian Peatmoss) were studied. For 'Casa Blanca', plant height and length of flower stalk increased when bulbs were planted in Pt:Rrh:Ve(1:1:1, v/v), and dried leaves of lower part plants decreased by RPt:Pe:Rrh(1:1:1, v/v). In case of 'Marco Polo' plant height and length of flower stalk increased with Pt:Rrh(1:1, v/v) as compared to other treatment, number of leaves and dried leaves increased when bulbs were planted in RPt:Pe:Rrh(1:1:1, v/v) as compared to control. Flowering of 'Casa Blanca' was promoted in Pt:Pe:Ve(1:1:1, v/v) and 'Marco Polo' was accelerated in Pt:Rrh:Ve(1:1:1, v/v). Flower length of 'Casa Blanca' was increased by RPt:Pe:Rrh(1 :1 :1, v/v) as compared with control and 'Marco Polo' was increased when bulbs planted to Pt:Rrh(1 :1, v/v). Flower-bud blasting of two cultivars was increased with Pt as compared with other treatment. Stem firmness of 'Casa Blanca' was increased by Pt:Pe:Ve (1:1 :1, v/v), and especially, stem firmness of upper part plants was increased by Pt:Rrh(1 :1, v/v) in 'Marco Polo' as compared to control plants. but generally, stem firmness of 'Casa Blanca' was not influenced with all cultural media as compared to control.

  • In order to improve the performance of a speech recognition system in the presence of noise, we propose a noise robust front-end using two-channel speech signals by separating speech from noise based on the computational auditory scene analysis (CASA). The main cues for the separation are interaural time difference (ITD) and interaural level difference (ILD) between two-channel signal. As a result, we can extract 39 cepstral coefficients are extracted from separated speech components. It is shown from speech recognition experiments that proposed front-end has outperforms the ETSI front-end with single-channel speech.

  • This study was conducted to investigate the effect of bulblet size on growth and bulb enlargement of Lilium Oriental hybrids, such as 'Sorbonne', 'Siberia', and 'Casa Blanca', grown in areas of high altitude (780 m), in 2009. The bulblets were oriented from tissue culture and planted to produce virus-free bulblets. All the three cultivars showed high vitality, with more than 93% producing shoots, even from small bulblets with a bulb circumference (BC) of less than 6 cm. Bulblets with BC 9-10 cm showed an increased height and number of leaves rapidly to induce the phase conversation from vegetative growth to reproductive growth. The bulblets of BC 9-10 cm in 'Sorbonne', 'Siberia', and 'Casa Blanca' had 2.0, 2.9, and 2.8 flower bud sets per plant, respectively. However, the flowers from those bulblets were not adequate as standard bulbs to produce cut-flowers for the domestic market. The larger bulblets showed more prosperous characteristics in growth and development of Lilium Oriental hybrids. Small bulblets had a high occurrence of viruses and leaf blight symptoms during cultivation, indicating the aggravated disease symptoms in the previously infected bulbs. 'Sorbonne' cultivars showed a high rate of enlargement of bulbs, and small bulblets under BC 6 cm produced more than 23% of the standard bulbs of BC 14-16 cm, which could produce cut-flowers for export. However, 'Casa Blanca' bulblets with BC 6-9 cm produced low bulbs of BC 14-16 cm at 21% level. 'Casa Blanca' cultivars had more bulb roots, longer root lengths, and higher weights than 'Sorbonne' and 'Siberia' cultivars. 'Casa Blanca' cultivars with BC over 9-10 cm grew rapidly and produced a high quantity of bulbs. In these results, 'Sorbonne' bulblets of BC 9-10, 'Siberia' bulblets of BC 10-12 cm, and 'Casa Blanca' bulblets of BC 10-12 cm produced 89%, 86%, and 93% of the standard bulbs of BC 14-16 cm, respectively. It is recommended that bulblets larger than the above sizes be used to produce cut-flowers for the export market. Experiment results suggest that production of bulbs larger than BC 18 cm requires bulblets that are larger than BC 12-14 cm of the three cultivars for the highest quality cut-flowers.

  • The objective of the study was to assess the general characteristics and motility characteristics with Computer Assisted Sperm Analyzer (CASA) system in Jeju horse semen. Semen was collected from 5 fertile Jeju horse by use of a Missouri type artificial vagina. Semen volume and pH were recorded, and sperm concentration was determined with a hematocytometer and motional characteristics of sperm were analysed by CASA. The viability and morphological abnormalities were assessed by a vital staining. The average volume of ejaculates was 42.5 ml and the average of sperm concentration was $198.5x10^6/m1$. The motional characteristics in Jeju horse semen was showed $70.4{\pm}28.7{\mu}m/s\;for\;VAP,\;69.6{\pm}28.9{\mu}m/s\;for\;VSL,\;94.1{\pm}30.0{\mu}m/s\;fo\;VCL,\;2.3{\pm}0.7{\mu}m/s\;for\;ALH,\;7.6{\pm}1.1Hz\;for\;BCF,\;99.1{\pm}1.2%\;for\;STR,\;and\;77.1{\pm}12.7%\;for\;LIN$. The percentage of sperm with abnormal head, midpiece and tail was 4.2%, 20.6%, 4.6% respectively.

  • The effects of MS salt strength, sucrose, and cultural conditions on bulblet formation and growth were investigated to optimize the conditions for micropropagating bulblets from in vitro bulb scales of Lilium Oriental Hybrid 'Casa Blanca'. There was no difference on bulblet formation in the range of 1/2~2 $\times$ strength of MS salt, but it was inhibited remarkably in 3 $\times$ strength of MS salt. The growth of regenerated bulblets was most stimulated on MS basal medium. Favorable bulblet formation and its growth from bulb scales were achieved when grown on the media with 1 : 2 or 1 : 3 in the ratio of NH$_4$^+ : NO$_3$^- , as well as on MS basal medium (NH$_4$^+ : NO$_3$^- = about l : 2). Therefore, MS basal medium was very suitable for bulblet formation and growth from bulb scales. Bulblet formation was inhibited but its growth was stimulated with increase sucrose concentration in the medium. The growth of regenerated bulblets was very effective on the media with 9~12% sucrose. Addition of activated charcoal (AC) to the medium inhibited bulblet formation from bulb scales, but enhanced the growth of regenerated bulblets. Especially, the medium containing 1 g/L AC was most effective on the growth of bulblets. No difference was found on bulblet formation and growth from bulb scales under light and dark conditions. In vitro micropropagation of L. Oriental Hybrid 'Casa Blanca' was supposed very reasonable to enhance the growth of the bulblets after forming of bulblets from in vitro bulb scales, and then, subculture the bulb scales from the grown bulblets on MS medium with 9% sucrose and 1 g/L AC.
