  • A Cymbidium variety 'Snow Bell' (C. kanran ${\times}$ C. Jack Frost) was developed at the National Institute of Horticultural & Herbal Science, Rural Development Administration in 2011. A cross between C. kanran with small-sized greenish colored flowers and C. Jack Frost with bright pink colored flowers, was conducted in 1999. Based on flower color, leaf shape, flower stalk, and vigor one line was selected. Evaluation and selection trials were conducted from 2006 to 2010. 'Snow Bell' has a light pink sepal (RHS, R56D), red lip (R56A) and a leaf length of 47.5 cm. The average number of flowers on each peduncle is 13.8 and the flower diameter is 6.2 cm. The characteristics of petals and sepals show some incurve and some spreading. 'Snow Bell' has a vigorous growth and a round flower. It has an adequate peduncle height of 50.7 cm compared with leaf length of 47.5 cm, and start blooming in December. In electronic nose analysis, the degree of fragrance between 'Snow Bell' and the C. kanran was similar and both of them showed strong scents, although they had different fragrance patterns.

  • The study has carried out to investigate the possibility of application of the emerged-peduncle at the 2 year -old plant for ginseng breeding. In the 2 and 3 year-old plant, growth habits of aerial parts of plants that had the inflorescence showed higher vigor in leaf length, number of leaves, rate of fruitage and fertility, and roots yield than those of non-inflorescence. Generally, characteristics such as stem diameter, stem length, leaf length and number of leaves showed highly significant positive-correlation with root weight and fruitage. The trends of characteristics of plant that has inflorescence at the 2 year-old plant was shown one-year faster pattern than the plant that has non-inflorescence. As these results, selection of the plants which have inflorescence at the 2 year-old plant will provide valuable aid for ginseng breeding.

  • The effects to the corticosteroid dexamethasone(DEX) and(or) estradiol-benzoate(E-B) treated to induction of parturition and birth weights of the young was conducted in 48 pregnant Korean native goats. The animals were divided into 4 goats per each treatment by the time(142, 145 and 148 day of pregnancy) and dosage(DEX 15, 20mg, DEX 8mg+E-B 10mg and DEX 13mg+E-B 7.5mg per goat). The results obtained were summarized as follows: 1 The time for induction of parturtion after DEX(15, 20mg) treatment on day 148 of pregnancy was significantly(P<0.01) shorter than 142 and 145 days. There was no significant difference each dosage of DEX on same day of pregnancy. 2. The addition of E-B to DEX treatment compared with DEX alone group at day 142 and 145 of pregnancy were significantly(P<0.01) shorter the time for induction of parturition. However, treatment with DEX along or with E-B on 148 day of pregnancy did not affect the time to induction(about 27 hrs) of parturition between each treatment. 3. The birth weight of kids after parturition was heaviest(P<0.01) on day 148 of pregnancy. However, development and vigor of kids were not significant different between DEX alone treatment and with E-B.

  • This study was conducted to investigate the effect of seedling age and irrigation set point on the growth and yield of white spined cucumber cv Sharp-1. Leaf area, number of lateral vines and root weight measured 70 days after planting were the greatest in 30 day-old seedling treatment. Inorganic element content measured 30 days after planting was the greatest in 30 day-old seedling treatment. Total and marketable yields were greater in 30 day-old seedlings than those of 20 or 40 day-old seedlings. The early yield was the least in 20 day-old seedlings. 40-day old seedlings lost vigor quickly. No significant differences in growth and yield observed as affected by irrigation set point.

  • In an effort to investigate the germination and growth characteristics of tannin containing forage crops (such as chicory, birdsfoot trefoil, Lotus pedunculatus, sulla, lespedeza, crownvetch, sainfoin), germinativity, seedling vigor, and productivity were studied. Although the cumulative germination percentage (CGP) of chicory and birdsfoot trefoil was low, the germination rate(GR) and days to reach 50% of final germination(Gt50) were excellent. Crownvetch, lespedeza and sainfoin showed poor germination. Chicory seeds were light but the rate of emergence and establishment were high. Seeds of Lotus pedunculatus and birdsfoot trefoil were also small, but their rates of emergence and establishment were quite good. On the other hand, seeds of sainfoin and crownvetch were heavy but their emergence and establishment rate were very low. Lespedeza was the best in getting over the hot summer, and crownvetch also survived well during summer. Chicory was good in productivity and early growing but its persistence was not good. In case of birdsfoot trefoil and Lotus pedunculatus their early growing were slow but their productivity and persistence were fairly well. Lespedeza, crownvetch, and sainfoin showed poor growth in Korea. Based on the results of this study it can be concluded that chicory would be better to use as short term high productive forage crop, and Lotus pedunculatus and birdsfoot trefoil could be used as continuous functional forage crops in Korea.

  • Large Eddy Simulation(LES) has been conducted to insight interaction effects of turbulent flow and chemical reaction of a lean-Premixed swirl combustor. The unsteady turbulent flame is carefully simulated so that the motion of flow and flame can be characterized in detail. Fuel lumps escaping from the primary combustion zone move downstream and consequently produce local hot spots conveying large vortical structures in the azimuthal direction. The correlation between pressure oscillation and unsteady heat release is examined by the spatial and temporal Rayleigh parameter.

  • Ecological factors limiting Stipa pulchra have been determined in experimental gardens and at several sites in the hills south and east of Monterey, California. The Stipa pulchrafacies of Valley Grassland communities were found to be dominated by that species, though a total of 36 grasses and forbs were collected and identified. Basal area was not large, but aerial cover by Stipa alone averaged over 50 per cent. Across an ecotone between a Stipa association and the California Annual Type a sudden and dramatic change was recorded. Soil measurements there, and in other nearby areas, showed a much higher clay content with more available water and elemental phosphorus at the Stipa sites. Germination of Stipa seeds was high under all laboratory and field conditions, though growth of seeldings was highly variable. Seedlings grown in Stipa woil with an abundance of water were vigorous and reached anthesis the first year. In other soils they grew less, and when grown in competition with Avena fatua they scarcely grew at all. These findings indicate that when established on desirable soils, Stipa competes well and apparently precludes the dominance of Avena fatua and other large annual grasses. On the other hand, because of a lack of vigor in its seedlings, Stipa cannot reinvade the rich more friable soils on which it was once found, and on which it was shown to grow satisfactorily. This supports the contention that Sipa pulchra was the dominant grass through much of the Valley Grassland and Foothill Woodland, but also indicates that well-drained soils and those poor in mineral nutrients probalby never supported such associations.

  • The works of the Futurism were developed along with manifestos and statement in publishing. Futurist aesthetic and ideological agenda on futurist fashion displayed in manifestos on clothes. Futurist fashion propagated in consummate Futurist style through the written manifesto. The Futurists anticipated much of modern fashion phenomenon. In Futurist Men's Clothing, men's clothing is aggressive, agile, dynamic, simple and comfortable, hygienic, gay, luminous, volatile, asymmetric and variable. In Futurist Manifesto on Woman's Clothing, woman is now a principal agent of revolt, a walking synthesis of the audacious, performance-oriented aesthetic of the futurist universe. For Futurist woman's clothing they claimed ingenuity, daring, and economy. The Futurist Manifesto of Italian Hat was continued with their provocative style and radical ambition. Their innovation will rescue a lagging Italian expert and restore the Italian male to his former Iatin Vigor. Speed, dynamic, utility, and funtionality are the main characters. In Futurist Manifesto of Italian Cravat, Futurist cravat is called Anti-cravatta, which is anti-traditional style and made of unconventional materials. In general, the Futurist argued for clothes that promoted simple and functionality. These Futurist fashion project were invention of the new style, avant-garde style, in daily wear and were realized for the renewal of taste in clothing design as a modernizing factors.

  • This report described a severe bilateral microphthalmia in a young Holstein calf. The anomalous calf with wry tail showed normal vigor, appetite and normal body weight except for eye defect. The orbits were shallower and smaller than normal. The orbit bilaterally contained a white small mass suspected as eyeball. A spot-like remnant of eyeball (REB) was buried in the mixture of vestigial extraocular muscles and adipose tissue of the bilateral orbit. Histologically, the REB was composed of irregularly arranged elements of ocular wall such as sclera, retina and ciliary body. But any destructive changes in the central nervous systems were not detected. This case of eye defect was defined as severe bilateral microphthalmia. The cause of this ocular defect is unknown.
