Objectives : Myristicae Semen is the seed of Myristica fragrans Houttuyn. Recently, the seed of Myristica argentea Warburg is also sold as a fake of Myristicae Semen. Thus, in order to distinguish Myristica fragrans Houttuyn and Myristica argentea Warburg, their external, internal, and flour states were observed via microscopic examination. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Result 1. The seed of Myristica fragrans Houttuyn is oval with a length of 2~3cm and diameter of 1.5~2.5 cm, while the seed of Myristica argentea Warburg is of a longer oval shape with a length of 2.5?3.5cm and diameter of 1.5cm. 2. There was no difference between the internal parts of the cross-sections of Myristica fragrans Houttuyn and Myristica argentea Warburg. 3. There was no difference between the flour states of Myristica fragrans Houttuyn and Myristica argentea Warburg. Conclusion : There was a distinctive difference between the external forms of Myristica fragrans Houttuyn and Myristica argentea Warburg, while there was no significant difference in their internal and flour states. This makes it difficult to distinguish them via microscopic examination, when cut by cross-sections or grounded into flour states. Therefore, they should be distinguished through TLC, or some research on the characterising compound is needed.

Before 1962 Taekwondo was not a sport that concerned the protection and care of the players, the role of judges, and the understanding of the spectators. At that period, Taekwondo's playing rules varied with each gymnasium that provided sporting grounds. Taekwondo matches were held in gymnasiums; no protective gear was provided or in use. A match persisted until one of the players was quelled; a single round was played. Different morals and rules were practiced in each gymnasium according to their founders. The "Leader" department held more contests than any other type of gym. They were held both indoors and outdoors. In the "Blue" department, a procedure was followed; therefore, 80% of the training course had to do with the basic behavior and formal forms of Taekwondo. 20% of the procedure were contests, which were held after the end of the training. Training of the spirit was also undergone to emphasize the spirit of martial arts. Each gym had its own training methords and programs.

Odontomas are odontogenic harmatomas which are composed of hard dental tissue. This lesion is composed of more than one type of tissue and, for this reason, has been called a composite odontoma. Odontogenic cysts are derived from epithelium associated with the development of the dental apparatus. Dentigerous cyst originated after the crown has been completely formed by accumulation of fluid between the reduced enamel epithelium and the crown. It also associated with crown of impacted tooth. Cystic odontomas are closely similar to dentigerous cysts clinically and radiologically. Treatment of choice is total removal(enucleation) or decompression(marsupialization). We represent two cases of Cystic odontomas with literature review in 69-year old male and 55-year old female occured in anterior maxilla. The leisions were successfully treated by marsupializaion.

Dental magnetic materials have been applied to removable prosthetic appliances, maxillofacial prostheses, obturator and dental implant but they still have some problems such as low corrosion resistance in oral environments. To increase the corrosion resistance of dental magnetic materials, surfaces of Sm-Co and Nd-Fe-B based magnetic materials were plated with TiN and then electrochemical corrosion test were performed in 4 kinds of electrolyte solutions(0.9% NaCl. 1% lactic acid, 0.05% HCl and modified Fusayama's artificial saliva). From this study, corrosion behavior, amount of elements released, mean average surface roughness values and the changing of mean surface microhardness values were measured comparing with control group of non-sputtered plating magnetic materials. The results were as follows: 1. TiN layer coated on magnet grows into preferred direction with lamellar structure and its thickness is 3.0㎛. 2. Sm-Co base magnetic materials coated with TiN have good corrosion resistance in 1% lactic acid and their pitting corrosion can not be seen. 3. Nd-Fe-B base magnetic materials coated with TiN showed good tendency of corrosion resistance in 0.05% HCl solution. 4. The amount of elements released from both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were more significantly decreased than that of uncoated magnetic materials. 5. The mean surface roughness values of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were smooth than that of uncoated magnetic materials after corrosion test. 6. The decreasing rate of microhardness of both Sm-Co and Nd-Fe-B base magnetic materials coated with TiN were lower than that of uncoated magnetic materials after corrosion test. 7. Dental magnetic materials coated with TiN produced various corrosion products such as TiO, TiO₂, Ti₂O₃on the surface and resulted in better corrosion resistance than uncoated magnetic materials. In conclusion, it is considered that the corrosion problem of dental magnetic materials could be solved to some extent by EB-PVD with TiN on the surface of dental magnetic materials.

Goat milk has a protein composition similar to that of breast milk and contains abundant nutrients, but its use in functional foods is rather limited in comparison to milk from other sources. The aim of this study was to prepare a goat A2 β-casein fraction with improved digestibility and hypoallergenic properties. We investigated the optimal conditions for the separation of A2 β-casein fraction from goat milk by pH adjustment to pH 4.4 and treating the casein suspension with calcium chloride (0.05 M for 1 h at 25°C). Selective reduction of β- lactoglobulin and αs-casein was confirmed using sodium dodecyl sulphate-polyacrylamide gel electrophoresis and reverse-phase high-performance liquid chromatography. The hypoallergenic property of A2 β-casein fraction was examined by measuring the release of histamine and tumor necrosis factor alpha from HMC-1 human mast cells exposed to different proteins, including A2 β-casein fraction. There was no significant difference in levels of both indicators between A2 β-casein treatment and the control (no protein treatment). The A2 β-casein fraction is abundant in essential amino acids, especially, branched-chain amino acids (leucine, valine, and isoleucine). The physicochemical properties of A2 β-casein fraction, including protein solubility and viscosity, are similar to those of bovine whole casein which is widely used as a protein source in various foods. Therefore, the goat A2 β-casein fraction may be useful as a food material with good digestibility and hypoallergenic properties for infants, the elderly, and people with metabolic disorders.
