This study was conducted to determine the effect of rooting promoters and light intensity on rooting and root growth of rose cuttings. The cuttings, both 'Noblesse' and 'Red Velvet', were rooted up to 100% with Rootone treatment, while less than 100% with other growth promoter treatments. In 'Red Velvet', percentage of rooting increased with increasing IAA, NAA, and IBA concentrations. In 'Noblesse', however, the rate increased up to $500mg{\cdot}L^{-1}$ in NAA and IBA, and $1000mg{\cdot}L^{-1}$ in IAA, and then decreased above the concentrations. In 'Noblesse', root number, length, and weight increased by Rootone treatment. In 'Red Velvet', root number, and length increased by IBA treatment, while root weight was highest in Rootone treatment. In both cultivars, rooting was accelerated and the rate increased under high light intensity and root growth increased also. Between both cultivars, propagation and root growth of 'Red Velvet' decreased dramatically with decreased light intensity.

The purpose of this study was to control root-knot nematode, Meloidogyne incognita on pumpkin seedling with 10%, 20% coffee ground compost and 1% plant velvet bean powder (plain skin bean, leopard skin bean, hole plant, bean pod). Among the root-knot nematode insecticide treatments, the velvet bean plant powder was the highest mortality rate with 83.2% in greenhouse condition. In addition, the root-knot nematode second juvenile mortality significantly increased with the lapse of processing time for each concentration of leopard skin velvet bean extract in vivo. After 24 hours, the mortality rate of root-knot nematode showed the highest at 1.2% and 2.4% of leopard skin velvet bean extract. The growth promoting effect of seedlings pumpkin, 20% of coffee ground compost treatments inhibited the growth of pumpkin seedlings and 1% the tiger pattern velvet beans powder was the most to promote the growth of pumpkin seedlings. However, the results indicated that the organic materials of velvet beans and coffee ground compost are expected to be able to effectively control the root-knot nematode and further studies will be needed for the concentration and application methods.

Drying process is very important for commercialization of velvet antlers. So far, artificial drying has mostly depended on experience of farmers resulting in low efficiency of drying, deterioration during drying, and contamination by dust and bacteria. Various drying techniques for high-quality production have currently been commercialized in some developed countries, and one of them is a drying technique using microwave. In this study, application of the technique using an electronic (microwave) oven for drying of velvet antler was investigated. The results of this study are as follows. 1. It was found that the drying period was significantly affected by cornification of velvet antlers. Accordingly, it can be assumed that the velvet antlers should partly be sliced to save drying period and required drying energy. 2. It was also found that the drying speed was changeable according to tempering period and even with same drying period. The tempering period should be controlled according to processing rate. 3. The results indicated that a repeated drying of 2-min drying and 3-min tempering is the most effective when a microwave oven was used. 4. The results also showed that the drying technique using microwave of electronic oven can be effectively used for drying of velvet antlers. 5. Only drying and tempering periods were examined in this study, however, ingredient change of deer antler after drying is necessary to be investigated in the future.

The aim of this study was to provide basic information to allow improved feeding management for velvet antler production by investigating the effects of dietary protein level on production and chemical composition of velvet antler in spotted deer(Cervus nippon). Eighteen male spotted deer of 5~6 years old were assigned to 3 unreplicated groups by production record of the previous year. Deer were fed on experimental diets at different protein level of 10%(T1), 15%(T2) and 20%(T3). Dry matter intake, crude protein intake and daily gain were increased with increasing the protein level in diets and there were significant differences(P<0.05) between groups. Although not significant, mean length of main beam tended to be longer in either left or right beam with increasing the protein level, and in girth at part of base of main beam, it was a similar pattern to the result of length. The velvet antler production was affected by dietary protein level and thus that was the smallest in T1 and the largest in T3(P<0.05). The content of crude protein in velvet antler was higher in T1 than in T3, whereas the content of crude ash in velvet antler was contrast to that of crude protein, however, there were no significant differences.

The study was conducted to investigate the effects of physical stimulus on casting day of antler, velvet antler yield, length of velvet antler in Sika deer(Cervus nippon). Eigthen(18) stags were assigned into the treatment with six(6) stags for treatment. Results revealed that at the start of the velvet antler growth, compulsorily casting both pedicles group was 15 days later at first cycle but 11-14 days earlier at the second cycle than control group(P<0.05). The yields of velvet antler in control group, casting only left pedicle group and the both pedicle group were 775g, 835g and 757g at the first cycle and 1,004g, 1,194g and 998g at the second cycle, respectively. The average length of antler in control group, casting only left pedicle group and both pedicle group were 25.8cm, 27.4cm and 31.5cm, respectively. The average length of antler of the casting only left pedicle group and that of the both pedicle group showed 1.6cm and 5.7cm in first cycle and 2.7cm and 2.4cm in second cycle longer than that of control group(P<0.05). Results of the study suggest the possibility of controlling velvet antler producing point through compulsory casting method.

Decoction of oriental medicinal preparation is prepared in various manners, and changes of chemical constituents might be occurred depending on the processing techniques. The present study was undertaken to investigate the phγsio-chemical and pharmacological equivalence between two extraction methods of Nokyong-sagunja-Tang. Samples were Prepared as follows ; Sample-I was prepared by simultaneously extracting Sagunja-Tang and velvet antler in one vessel. Sample-lI was prepared by adding velvet antler exact to the water extract of Sagunja-Tang. Both sanples showed similar results of physiochemical parameters such as pH, yield, TLC and HPLC chromatogram, and contents of ginsenoside $Rb_1$ and glycyrrhizin. Also, there were little different between two samples in pharmacological effects such as DPPH free radical scavenging effect, and inhibitory effects on xanthine oxidase, hyaluronidase, trypsin, TBA-Rs formation and hemolysis in vitro. And both samples showed no significant difference in antifatigue activities in mice. These results suggest that there might be little difference between two extraction process when velvet antler added to Sagunia-Tang.

The purpose of this study is to understand what the Glam Style is, focus on the movie "Velvet Goldmine". The Glam Style is refered early 1970s Glam rockers' costume, typified by silver lurex, corksoled platform, men in make-up, personified, for example, by David Bowie, Marc Bolan, New York Dolls, Roxy Music and Iggy Pop. To approach the Glam Style comprehensively, I have divided the formative background of Glam Style into the improvement technology, the advent of the young generation and the diffusion of mass media, the rock music fever and influence on Pop art. Following is the result of analyzing of the character in the movie. First, Brian Slade has the flamboyant transsexual image by skin-tight space suit, glitter pants, lurex, satin and sequined stretch fabrics, vivid color, gauze make-up, feather boa. Second, Curt Wild expresses the outrageous sexual image by black leather jacket, emphasized black eyes make-up. Third, Mandy Slade appears the exaggerated and frivolous image by gold leopard patterned one piece, fur coat, ornamented with beads, tropical make-up, spangles and the costume jewelry. Forth, Auther Stuart has the complex image by black leather jacket, velvet jacket, skin-tight bold shirt, glitter pants, glitter make-up, silk scarf, cherry-red sunglasses. The characteristics meaning of Glam Style implied in this formative characteristic could be presented as the experimental expression of androgynous, the hordes of outrageous alien and kitsch parody.

This study was carried out to evaluate the change of blood constituents during the growth of antlers in Korean spotted deer (Cervus nippon). Samples of blood, obtained from the jugular vein of twenty five deer (3 to 6 year-old males) were taken in 10 days interval from casting to cutting of antler and were analyzed the blood parameters. Total-protein concentration in blood serum showed significantly differences during growth period of velvet antler (p<0.01), and it had similar tendency for total protein and albumin concentration, but albumin concentration was about 40-45% of total protein concentration. Urea and creatinine concentration was tended to inverse proportion, and it was almost 30:1 for ratio of urea and creatinine concentration. The concentration of total protein, creatinine, and uric acid concentration in blood during growth period of velvet antler was similarly increased and decreased but urea concentration was opposed. The concentration of total-bilirubin and direct-bilirubin at casting was higher than those at other period(P<0.05).

Recently, interest in food-derived bioactive peptides as promising ingredients for the prevention and improvement of hypertension is increasing. The purpose of this study was to determine the structure and antihypertensive effect of an antioxidant peptide purified from velvet antler in a previous study and evaluate its potential as a various bioactive peptide. Molecular weight (MW) and amino acid sequences of the purified peptide were determined by quadrupole time-of-flight electrospray ionization mass spectroscopy. The angiotensin I-converting enzyme (ACE) inhibition activity of the purified peptide was assessed by enzyme reaction methods and in silico molecular docking analysis to determine the interaction between the purified peptide and ACE. Also, antihypertensive effect of the purified peptide in spontaneously hypertensive rats (SHRs) was investigated. The purified antioxidant peptide was identified to be a pentapeptide Asp-Asn-Arg-Tyr-Tyr with a MW of 730.31 Da. This pentapeptide showed potent inhibition activity against ACE (IC₅₀ value, 3.72 μM). Molecular docking studies revealed a good and stable binding affinity between purified peptide and ACE and indicated that the purified peptide could interact with HOH2570, ARG522, ARG124, GLU143, HIS387, TRP357, and GLU403 residues of ACE. Furthermore, oral administration of the pentapeptide significantly reduced blood pressure in SHRs. The pentapeptide derived from enzymatic hydrolysate of velvet antler is an excellent ACE inhibitor. It might be effectively applied as an animal-based functional food ingredient.
