After making tea by steaming the Burdock(Arctium lappa) nine times and drying it nine times, the ingredients and functions of the Burdock tea were compared to those of M company. The tea's calories were 346.48kcal/100g, carbohydrates were 72.75g/100g, crude protein was 11.98g/100g, and crude ash was 5.01g/100g. The total of free sugars were 31.93mg/100, among them, fructose was 26.27, sucrose was 1.27 mg/100g. The inorganic material contents were 1,476.21mg/100g of potassium, 255.96 mg/100g of calcium and 311.41 mg/100g of magnesium. The saturated fatty acids were 40.73mg/100g and the unsaturated fatty acids were 59.27mg/100g, among which the linoleic acid was 41.28mg/100g, the palmitic acid was 33.11mg/100g, the oleic acid was 10.07mg/100g and linolenic acid was 7.92mg/100g. DPPH radical scavenging was 33.9% of teas that were developed, 2.3% of M's tea for comparison, and 37.2% of indiex material. ABTS radical scavenging were 90.7% of teas developed, 85.9% of M's tea and 37.2% of index materials, and SOD like activities were 11.3% of teas developed and 50.5% of M's teas. The flavonoid content was 2.6 fold of the tea developed, 2.9 fold of M's tea and 1.7 fold of index material. The polyphenol content was 33.8 fold of teas developed, 38.9 fold of the M's tea and 13.8 fold of the index material. The sensory evaluation compare to the one-time extract and the five-time extract. Based on the one-time extract, the color were 65.9 % of the five-time extract tea were developed, 12.8 % of the M's tea. Flavour were 78.0% of the tea developed and 33.3% of the M's tea, tastes were 71.4% of the tea developed, 20.7% of the M's tea. The cart for comparison showed that while the extract decreased as we developed it, the overall symbolism decreased to 21.4% after five time extracts, the developed tea decreased to 72.1%. We believe that the developed tea will have a greater effect on preventing and improving diseases as it has a stronger antioxidant function, more effective substances, and a higher level of symbolism than the comparative M squared tea and surface substance.

This study was conducted for comparison of ingredients, phytochemical compounds and antioxidant activity of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do, and Jeolla-do. Three contents of Wofiporia extensa were analyzed as oxygen (46~48%), carbon (38~39%), hydrogen (6.05~6.1%) and nitrogen (0.17~0.21%). The mineral contents of 50% ethanol Wofiporia extensa extracts were measured as sulfur (S) 145~149 ppm, Magnesium (Mg) 69~72 ppm, phosphorus (P) 122~154 ppm and calcium (Ca) 210.61~509.98 ppm. Wofiporia extensa from Gyeongsang-do (509.98 ppm) contained a significantly higher quantity of Ca than that from Gangwon-do (210.62 ppm) and Jeolla-do (223.88 ppm). In the gas chromatograph-mass spectrometry (GC-MS) analysis, oleic acid was identified in three 50% ethanol Wofiporia extensa extracts. In the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay for antioxidant activity, the $IC_{50}$ values of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do and Jeolla-do were calculated as 2.966 mg/mL, 23.03 mg/mL, and 4.16 mg/mL and 3.521 mg/mL, 12.17 mg/mL, and 7.40 mg/mL. In the ferric reducing antioxidant power (FRAP) assay, the $IC_{50}$ values of Wofiporia extensa cultured in Gangwon-do, Gyeongsang-do, Jeolla-do were 6.585 mg/mL, 19.06 mg/mL, and 18.97 mg/mL, respectively. In summary, Wofiporia extensa cultured in Gangwon-do had stronger antioxidant activity and higher concentration of oleic acid than that of Geyongsang-do and Jeolla-do. However, Wofiporia extensa cultured in Geyongsang-do contained a much higher concentration of Ca than that of Gangwon-do and Jeolla-do.

Titanium and its alloys are widely used as implants in orthopedics, dentistry and cardiology due to their outstanding properties, such as high strength, high level of hemocompatibility and enhanced biocompatibility. Hence, recent works showed that the synthesis of new Ti-based alloys for implant application involves more biocompatible metallic alloying element, such as, Nb, Hf, Zr and Mo. In particular, Nb and Hf are one of the most effective Ti ${\beta}-stabilizer$ and reducing the elastic modulus. Plasma electrolyte oxidation (PEO) is known as excellent method in the biocompatibility of biomaterial due to quickly coating time and controlled coating condition. The anodized oxide layer and diameter modulation of Ti alloys can be obtained function of improvement of cell adhesion. Silicon (Si) and magnesium (Mg) has a beneficial effect on bone. Si in particular has been found to be essential for normal bone and cartilage growth and development. In vitro studies have shown that Mg plays very important roles in essential for normal growth and metabolism of skeletal tissue in vertebrates and can be detected as minor constituents in teeth and bone. The aim of this study is to research Si and Mg doped hydroxyapatite film formation by plasma electrolytic oxidation. Ti-29Nb-xHf (x= 0, 3, 7 and 15wt%, mass fraction) alloys were prepared Ti-29Nb-xHf alloys of containing Hf up from 0 wt% to 15 wt% were melted by using a vacuum furnace. Ti-29Nb-xHf alloys were homogenized for 2 hr at $1050^{\circ}C$. Each alloy was anodized in solution containing typically 0.15 M calcium acetate monohydrate + 0.02 M calcium glycerophosphate at room temperature. A direct current power source was used for the process of anodization. Anodized alloys was prepared using 270V~300V anodization voltage at room. A Si and Mg coating was produced by RF-magnetron sputtering system. RF power of 100W was applied to the target for 1h at room temperature. The microstructure, phase and composition of Si and Mg coated oxide surface of Ti-29Nb-xHf alloys were examined by FE-SEM, EDS, and XRD.

In this study, two kinds of chestnut-sweet potato (CSP) and pumpkin-sweet potato (PSP) were cooked by three methods: raw, steaming, and roasting. These samples were investigated in food compositions such as moisture, protein, ash, dietary fiber, fat, minerals, and vitamins. As the results of this study, the moisture contents of raw CSP and raw PSP were higher than those of steamed and roasted samples in two cultivars. The contents of protein in raw CSP and raw PSP were 2.57 g/100 g and 3.22 g/100 g, respectively, which were higher than those of other cultivars. The protein contents of roasted CSP and steamed PSP were lower than those of their raw samples. The potassium, phosphorus, magnesium, calcium, sodium, and iron values of PSP were 1,048.46 mg/100g, 152.02 mg/100g, 74.70 mg/100g, 57.22 mg/100g, 22.28 mg/100g, and 1.44 mg/100g, respectively, which were the highest values in tested sweet potato cultivars. The content of dietary fiber in CSP was higher generally than that in PSP. The values of total dietary fiber in cooked sweet potatoes were higher than those of raw sweet potatoes. The contents of vitamins, including thiamine, riboflavin, and niacin, in PSP were higher than those in CSP. Overall, two cultivars of raw, boiled, and roasted sweet potatoes had enhanced food composition. Therefore, these sweet potato cultivars are expected to be highly valuable food items for the development and application of functional foods.

The compositions of non-volatile organic acids, mineral, fiber and fatty acids of leaf mustard were investigated. Non-volatile organic acid contents were higher in leaf than in leaf stalk. Of non-volatile organic acids assayed malic acid was the most abundant in both leaf (79.1 mg%) and leaf stalk (46.4mg%), followed by L-ascorbic, oxalic, citric and succinic acids. Mineral contents were also higher in leaf than in leaf stalk. Both leaf and leaf stalk contained calcium most, followed by magnesium, sodium, iron, zinc and copper. It has also been found that leaf mustard contains more iron than any other Cruciferous vegetables reported. The major fatty acid of total lipid was $\alpha$-linolenir acid (63.2% in leaf, 55.3% in leaf stalk). The ratios of polyun-saturated fatty acids to saturated fatty acids (P/S ratio) were 4.1 in leaf and 2.9 in leaf stalk. The content of pectic substances, in terms of alcohol-insoluble solid, of leaf was 9.4% which was 1.4-fold higher than that of leaf stalk. Of pectic substances, hot soluble pectins (HWSP) were present most and followed by sodium hexametaphosphate soluble (HXSP) and HCI soluble pectins (HSP). Total dietary fiber content of mustard leaf was 2.68% and in general, higher content of total dietary fiber than leaf had. Neutral detergent fiber content was higher than acid detergent fiber, and cellulose was higher than hemicellulose by 2.1-fold in leaf stalk.

High-salted mineral water (Daehan Deep Water, Korea) that is pumped up from below the sedimentary rock layer of Dadaepo, Busan, Korea has a composition similar with that of deep sea water. Under the well-being boom, the mineral water is processed for various uses including washing or oral administration. However, high concentrations of various minerals in the mineral water are suspected to affect on the physiology of human body, especially on blood pressure (BP). Here, we examined the effect of Hot Mineral(R), dried powder of the mineral water, on the change of BP. Sprague­Dawley rats were grouped and orally administered $2.5\%$ Hot Mineral(R) (group M), $2.5\%$ NaCl (group S) or normal water (group C). Excreted urine was collected in metabolic cage for 24 hours. The systolic blood pressure (SBP) of the group S was remarkably increased (P<0.005) compared with that of the group M and the group C, which showed little changes of the SBP during 2 weeks. While average daily sodium intake were 0.32 mg in the group C, 6.64 mg in the group M and 4.07 mg in the group S, average daily sodium excretion were 11.37 mg, 53.70 mg and 7.75 mg, respectively. These results indicate that the sodium excretion in the group M was much higher than the other two groups. In this study, we suppose that the plenty amount of minerals such as calcium, potassium and magnesium in Hot Mineral? have an effect not to increase the SBP and to prompt sodium excretion out of the body. Therefore, these results suggest that oral administration of appropriate amount of Hot Mineral(R) for limited period does not induce increased SBP.

The purpose of this study is to analyze the proximate components (water, crude ash, crude protein, crude fat, and carbohydrates) and nutritive components (vitamin A, C, E, minerals, amino acids, and fatty acids) of rice flour and develop several rice bread recipes using rice flour. The water, crude ash, crude protein, crude lipid, carbohydrate contents of rice flour were measured to be 8.53%, 0.10 g, 6.80 g, 0.14 g and 84.43 g, respectively. No vitamin A was detected in the rice flour, and vitamin C and E contents were found to be 8.30 and 0.3467 mg/100 g, respectively. Calcium, potassium, magnesium, iron, and sodium contents were measured as 6.23, 65.05, 9.78, 0.17 and 2.84 mg/100 g; the large amount of potassium helps to discharge the sodium. Rice flour has nine kinds of essential amino acids in it; essential amino acids form 45.15% of rice flour's content. which is higher than 32.3%. Fatty acids were barely detected in the rice powder; saturated fatty acids were measured as 31.25 mg/100 g, and unsaturated fatty acids as 25.54 mg/100 g. Regarding essential fatty acids, linoleic acids were measured as 41.01 mg/100 g, and linolenic acids as 2.20 mg/100 g. The researcher used rice loaf bread as the base and developed rice bread recipes using rice flour to make a total of 11 items: 8 items with 75% rice flour (rice bagel, rice sweet red-bean bread, rice butter roll bread, rice mocha bread, rice buttertop bread, rice custard cream bread, and rice streusel), 2 items with 80% rice flour (stollen and rice hobbang), and 1 item with 85% rice flour (rice donut).
