This paper examines the origin of the current Nigerian Yoruba artistic and cultural tradition through ancient artifacts and creation myths centered on $Il{\acute{e}}-If{\acute{e}}$ (or $If{\acute{e}}$) located in the southwestern part of Nigeria and recognition of cultural relativity. In the oral tradition, kingdoms of Ijebu, Oyo, and Benin all have their origins in the ancient city of $Il{\acute{e}}-If{\acute{e}}$, the cradle of Yoruba culture. Their founders were sons of Oduduwa, the god of Yoruba. In this way, kingdoms built around $Il{\acute{e}}-Ife$ were closely connected with culture, religion, and society. In order to understand the Yoruba culture, research on $Il{\acute{e}}-Ife$, the source of their artistic and cultural traditions, is very important. The Yoruba are deeply rooted in $Il{\acute{e}}-Ife$. They have been steadily preserving their artistry since the beginning. They have been using it in their lives to this day for centuries. Their evidences are mythology and Ifa divination system. They are cultural heritages that represent the art of Yoruba and the spiritual culture. Ifa devination system is one of Yoruba traditions associated with Yoruba gods 'Eshu' and 'Ifa'. It has been conducted among the Yoruba until now. If the culture and civilization of Africa, including these Yoruba traditional customs, are deemed illogical and superstitious, it would mislead their efforts to preserve the origin in its original form. If so, one should understand the relativity of other cultures and civilizations and the need for diversity and flexibility of value standards to judge their cultures and civilizations.

The purpose of this study was to compare the bond strength of resin-modified glass ionomer (RMGI) to dentin with saliva contamination at different stages and using different decontamination procedures. Extracted human permanent molars were embedded onto acrylic resin with the dentin surface exposed. Group I was a control group that was conditioned with polyacrylic acid (PAA). Groups II and III were contaminated with saliva before PAA conditioning and Groups IV, V, and VI were contaminated with saliva after PAA conditioning. After saliva contamination, Groups II and IV were dried, Groups III and V were rinsed and dried, and Group VI was additionally conditioned with PAA. After surface treatment, the dentin specimens were filled with RMGI. Group I showed significantly higher bond strength than the other groups. Group VI showed a significantly higher bond strength than the other saliva contaminated groups. However, there were no significant differences in the failure mode between the different groups. Saliva contamination impaired the bond strength of RMGI to dentin, regardless of when the saliva contamination occurred. Decontamination with washing and drying could not improve the shear bond strength of RMGIC. When saliva contamination occurred after PAA conditioning, additional PAA conditioning improved the shear bond strength.

Korean ginseng has been used for centuries in traditional Chinese medicine as an overall wellness supplement. Red ginseng (Ginseng Radix Rubra) is produced by steaming the roots, followed by drying. Soft red ginseng is produced using a new processing technology. This study investigated whether soft red ginseng differs from raw and hard red ginseng in its physicochemical composition. Results showed that the total phenol content of raw ginseng was 2.96 mg/g at 80℃ and 3.47 mg/g at 160 ℃. Meanwhile, the total phenols of hard and soft red ginseng were 4.12 mg/g and 4.18 mg/g at 160℃, respectively. The total phenol contents of raw, hard red, and soft red ginseng revealed a statistically significant difference (p>0.05). The total flavonoid contents of raw, hard red, and soft red ginseng were 2.62 mg/g, 3.97 mg/g, and 3.83 mg/g at 160℃, respectively. Among the three samples, soft red ginseng had the highest total sugar content at 160℃. The acidic polysaccharide contents of both soft and hard red ginseng were much higher than that of raw ginseng (49%-58%). Significant differences were observed among raw, hard red, and soft red ginseng (p<0.001). Soft red ginseng exhibited higher phenol content (25%), total flavonoid content (49%), and total sugar content (45%) than raw ginseng.

Hydration process is one of the basic carbonation system. Limestone sludge produced in Pohang Iron & Steel Co., Ltd. We tested for identify of hydration characteristics. The result obtained in this study can be summarized as follows; 1. The classify of limestone sludge is type of ground calcium carbonate(-3mm+325mesh)and the major mineral of calcite, and further more high grade(CaO 51%), fine powder(15~22$\mu\textrm{m}$). 2. Limestone sludge mixed two process sludge, first one is washing process sludge and the other one is wet collect kiln dust. The composition rate is about 8:2. Wet collect kiln dust is major mineral of calcite, too. But the sludge is assumed to one by quick lime, slaked lime and unreacted natural limestone. So, the ideal process is dividing of the washing process sludge and wet collect kiln dust. 3. We manufactured of slaked lime from limestone sludge. To investigate the effect of hydration reactor, the experiments was done with various reactor type as magnetic stirrer, shaking incubator and ultrasonic vibration reactor, respectively. Generally, ultrasonic vibration reactor is excellent hydration for limestone sludge and produced very fine slaked lime powder with ideal distribution. 4. The optimum condition is 10% pulp density, when the manufacture of fine slaked lime powder by ultrasonic vibration reactor. And hydration times to compare the results of the study with ultrasonic vibration reactor of generalized most short time(5~10 min). 5. Finally, the dispersive characteristics of slaked lime powder measured 1~5 $\mu\textrm{m}$ from limestone sludge were compared with those of natural limestone ones(10~20$\mu\textrm{m}$), in order to check applicability of slaked lime with hydration process from limestone sludge.

Cryoprotective effects on chicken surimi during storage were investigated. Chicken surimi from mechanically deboned spent layer meat was prepared with 4 volumes of 0.5% NaCl washing, and then blended with or without cryoprotectants (8% trehalose, 8% oligosaccharide) prior to frozen storage at $-18^{\circ}C$ to 10 weeks Redness (a) of all surimi decreased during storage. Color stability increased during storage when lightness increased but redness decreased. At this Point, surimi maintained a better color quality as followed order; trehalose > oligosaccharide ) non-additive. Gel strength such as compressive force, hardness, adhesiveness and gumminess tended to decrease during frozen storage. Cryoprotectants provided significantly better textural properties than non-auditive. Surimi with trehalose showed the highest adhesiveness. In conclusion, trehalose and oligosaccharide seemed to be good cryoprotectants of chicken surimi. Especially, trehalose resulted in better cryoprotectant than oligosaccharide because of better color stability, better textural properties, and lower sweet characteristics.

Peony is commonly used as roots that peeled and dried. But intact root contains higher medicinal constituents than peeled root (machine peeling). The yield of roots was also higher in intact roots. Use of intact root saved the labor time for peeling and 15% of root from yield loss by peeling. Paeoniflorin content was different with each zones of root. The content of Paeoniflorin was 5.11% in epidermis and 3.28% in cortex. When peeled peony roots were dried at hot air after briquet fire drying, root color was good for commercialization. But color of intact root was good at hot air drying without briquet fire drying. The required time for drying was longer in drying of intact roots than peeled roots drying.

Zinc alginate films were prepared by a film maker from sodium alginate solutions of different weight ratios and then they solidified into 3 wt% content $ZnCl_2$ coagulation solution and washed and dried at a $60^{\circ}C$ oven for 20 min. The characteristics were measured by several methods (antimicrobial activity, viscosity, FTIR, TGA, SEM, EDS, contact angle, tensile strength and solubility) and the film properties were investigated. The antimicrobial test showed that the zinc alginate films result in excellent antimicrobial activity in the two strains (Klebsiella pneumonia, Staphylococcus). The surface of zinc alginate film from the solution of 9 wt% sodium alginate showed more uniform shape than any other films and the cross-section were hard and rough when the films were well-solidified by the $ZnCl_2$ solution. The tensile strength of zinc alginate films increased along with the concentration of sodium alginate solution due to the cross-linking, and the initial thermal decomposition temperature increased gradually.
