Furniture is a medium to interconnect the living space to human, and it is the closest environmental element that limits the functions of the space, defines the style of the living, and adjusts the actions and behaviors of human. Therefore the furniture can be said to be one of the craft arts that reflects the culture and living style as they are according to the periodical, regional, and social stratum characteristics. Within this context, this study tries to suggest new design and living culture that can harmonize with the modern residence living culture and incorporate the traditional varnishing technique with lacquer that had been discontinued. Coming to the modern days, the varnishing with lacquer is getting attention again with its environment friendly characteristics and antibiotic functions, and is being applied to various applications. To inherit and maintain such an excellent traditional culture, I would like to improve the practicality by applying to modern furniture, and to contribute to develop and tell the world about the superiority of our culture.

This study compares and analyzes inorganic components of four different Pu-erh tea species consumed in Korea. The criteria for the inorganic components was based on the Royal Institute of Technology (KTH) recommendations. Out of the 19 general items: potassium, manganese, silicon and fluorine were detected in amounts exceeding the maximum allowable concentration by 5~23, 57~91, 1.6~1.8 and 9~18 times respectively. Out of the 15 potentially harmful elements: aluminum and nickel were exceeded the Maximum allowable concentration by 9~14 times and 0.8~1.2 times respectively. To reduce the concentration of inorganic elements in excess of the maximum allowable concentration, the extraction time of tea should be less than 1 minute in addition to limiting the amount. The amount of Pu-erh tea for extraction was about 0.1 g manganese, about 0.3 g potassium, about 0.5 g fluoride and about 2 g silicon. Therefore, the maximum amount of tea for extraction should be 0.1 g in regards to the safety of Pu-erh tea. Based on the recommended maximum daily intake of inorganic ingredients by the Ministry of Food and Drug Safety, it is desirable that the number of extractions be less than three.

Various types of tea have been cultivated to obtain different flavors and enhance their functional properties. The objective of this study was to investigate the physicochemical properties of γ-aminobutyric acid (GABA) teas produced from commercial Korean green, white, and black teas. The concentration of total minerals was reduced in GABA green tea and GABA white tea but was improved in GABA black tea. The essential, non-essential, and total free amino acid contents were remarkably increased in the GABA teas. The amino acid GABA content was increased by 561.00 and 294.20 times in GABA white tea and GABA black tea, respectively. The antioxidant potential was not reduced, although the total polyphenol and total flavonoid contents decreased in GABA green tea and GABA black tea. The results indicated that the overall nutritional value of commercial green, white, and black teas could be improved by processing them into GABA teas.

Optimum leaching conditions of Korean green tea were determined by examining the relationship between sensory evaluation and tasting constituents of green tea infusion at various leaching conditions. Total nitrogen, total reducing sugar and tannin contents of green tea were $4.70{\sim}5.02%$, $16.5{\sim}18.0%$ and $10.3{\sim}12.7%$, respectively. They increased with the increased of leaching temperature and time. The sensory score was significantly correlated with the tannin contents of green tea in fusion in the range of $15{\sim}30\;mg/g$.(r=-0.9061). Optimum leaching conditions of green tea were $0.5{\sim}1.0$ min at $55^{\circ}C$, 0.5 min at $70{\sim}85^{\circ}C$ in high grade parched green tea, $1.0{\sim}2.0$ min at $55^{\circ}C$ and $0.5{\sim}1.0$ min at $70^{\circ}C$ in medium one.

This reserch was carried out to investigate the nitrite scavenging abilities (NSA) of 7 kinds of tea extracts. Nitrites are used as additives of cured meat preperation and exist in plants, foods, and medicines, so we intake it very often easily. Nitrites can act with amines to produce nitrosamine which is known to be a carcinogen. It is known that the pH, concentration of amines, and amounts of nitrite are three important conditions of nitrosamine occurence. 7 kinds of tea used in this experiment were Persimmon tree (Diospyroo kaki Thiunb, Per.), Mulberry tree (Morus alba Linne, Mul.), Rubber tree (eucommia ulmoi-des Oliver, Rub.), Solomon's-seal (Bolygonatu Morr, Som.), Chicory (Cichorrium intybus L, Chi.), Sumach (Rhus javanica L., Sum.), Docwood (Cornus officinale Sieb, Doc.) and they were extracted with methanol (MeOH), ethyl ether (EtEt), ethyl acetate (EtAc), and also the extract existed in the aqueous layer II (Aq L. II) was used.

This study was performed to make new products rising Pimpinella brachycarpa N., one of the Korean aromatic medicinal plant called chamnamul, which is a perennial plant of the Umbelliferae family. New products were natural chamnamul spice, chamnamul soup, chamnamul tea, and chamnamul mook as functional foods. The masking effect of Pimpinella brachvcarpa N., on fishy and meaty odor were investigated to test the usefulness of chamnamul as a natural spice. It could be concluded that the effect of added amounts of chamnamul on the cream soup increases the taste and appearance, and improves the flavor and color by the sensory evaluation. The chamnamul tea prepared by a filtration method is better than that by a leaching method on the preference test. In the texture properties of chamnamul mooks by a texture analyzer (XT-RA, Texturometer), the cohessiveness of them was higher than that of the white one.
