Edible red algae paper coated with green tea ext Tact was prepared and determined the microbial growth and quality change of kimbab wrapped with the paper during storage. The paper coated with green tea extract had the antimicrobial activity against Listeria monocytogenes and Escherichia coli. After 12 hr of storage of kimbab, packaging with the paper coated with green tea extract decreased populations of total aerobic bacteria by 1 log cycle. Kimbab wrapped with the red algae paper coated with green tea extract had 5.5 mg malondialdehyde (MDA)/kg after 12 hr, in contrast to the control of 7.4 mg MDA/kg. Kimbab with red algae paper with green tea extract was better than the control in terms of sensory qualities. These results clearly indicate that kimbab can be packaged with red algae paper coated with green tea extract, resulting in extending its shelf life.

The attitude of Eco-friendly clothing is based on environmental awareness and Low-carbon green growth awareness. It can be developed through our education. I studied and analyzed the survey which targeted on highschool students whether the recognition of low-carbon green growth can be effected to the eco-friendly clothing attitude or not, and school education effect. The research shows the green growth recognition affects significantly to the eco-friendly clothing attitude. Also the study proves the education of green growth awareness and the eco-friendly clothing attitude informs the realizations of environmental and green growth concepts. The education of clothing habits affects our eco-friendly clothing attitude. Therefore this education is necessary for school curriculum and it must be expanded in any areas both in 'environment and green growth' course and 'home economics' courses in secondary education. The education of Eco-friendly clothing habit should be keep researched specifically and develop further and further.

The aim of the study is to look at the relationships among emotional dimensions, commitment to environment, consumer typology, and quality of life. For this study, 303 students completed the questionnaires and SPSS and Amos 4 were employed. The findings are: First, positive emotion increases commitment to environment. Second, commitment to environment encourages green consumer behaviors and quasi-green consumer behaviors while it reduces non-green consumer behaviors. Third, green consumer behaviors increase quality of life while quasi-green consumer behaviors and non-green consumer behaviors do not have any influence on quality of life. Some practical implications are included.

This study analyzed the changes of chlorophyll and ascorbic acid contents according to the extraction temperatures and the number of soakings using five kinds of Korean and Japanese green tea(3 kinds of green tea and 2 kinds of tea bag) which were obtained from local markets in Korea and Japan. The findings are as follows: 1. The chlorophyll contents of Japanese green tea were $2\sim3$ times higher than those of Korean green tea. 2. The chlorophyll contents of Korean green tea in high and middle grades were increased with increasing temperature $(80>70>60^{\circ}C)$ but the contents in low grade were increased with decreasing temperature. The contents of chlorophyll in Japanese green tea were almost similar in low, middle and high grades. 3. Ascorbic acid content was higher in low grade Korean green tea but it was higher in high and middle grades of Japanese green tea. Chlorophyll contents of Japanese green tea were higher than those of Korean green tea but ascorbic acid contents of Korean green tea were higher than those of Japanese green tea.

The purpose of this study was to examine the elements of green life education reflected in the Korean and Japanese secondary school Home Economics curricula. Although sustainable living at home has been emphasized as one of the main issues of Home Economics since the first curriculum period, green growth education has more reinforced in recent revised Home Economics Curricula of both countries. Thus the 2007 revised secondary school Home Economics Curriculum of Korea and 2008 revised middle school and 2009 revised high school Home Economics Curriculum of Japan were analyzed. The content analyses were done to examine the elements of green life education reflected in 'Characteristics and Objectives', 'Contents', and 'Teaching learning/Contents dealing Strategies' parts of the curriculum through two checking steps. The elements of green life education were included in all parts of the Home Economics Curricula of both countries except the 'Characteristics and Objectives' part of Japanese Curriculum. In both the Korean and Japanese Curricula, the element of green life was the most frequently and concretely reflected in the 'Contents' part, contrary to the 'Characteristics and Objectives' part where the element was the most rarely and abstractly reflected. The practical aspects of the green life education were more emphasized than the theoretical ones in both countries' curricula. The green life educational elements need to be included in all parts of Home Economics curriculum with concrete manner to ensure these elements to be reflected in Home Economics textbooks and to be actively implemented in classroom.

The cytotoxicity of coffee-like green tea (CLGT) was determined in a human breast cancer cell line, MCF-7; a human prostate cancer cell clone, PC-3; a human neuroblastoma cell line, SK-N-SH; and a rat cardiomyoblast cell line, H9c2, with reference to green tea leaves (GTL). The CLGT was prepared by roasting the GTL for 60 min at $240^{\circ}C$ in a temperature-controlled frying pan. The CLGT preparation imitated the flavor and taste characteristics of coffee fairly well according to sensory analysis. The CLGT preparation had no adverse cytotoxic effects on the cancer cells or the normal cells compared to GTL. No significant change in the antioxidant activity was seen in the CLGT preparation compared to that of GTL. The amount of total protein, sugar, and phenolic compounds was reduced in the preparation relative to those in GTL, a fact that might explain the coffee-like flavor and/or taste characteristics of the CLGT preparation. These results suggest that CLGT prepared by roasting GTL for 60 min at $240^{\circ}C$ does not show any adverse effects on cancer cells and normal cells compared to GTL. They imply that CLGT could be safe for human consumption.

To evaluate hepatoprotective effects, the antioxidant capacities of matcha green tea extract (Camellia sinenesis) were compared to those of green leaf tea and the anti-inflammatory activities in HepG2 cells were investigated. Evaluation of the total phenolic and total flavonoid content, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, and inhibitory effect on lipid peroxidation indicated that the aqueous extract of matcha green tea presented significant catechin content and antioxidant capacity compared to those of green leaf tea. In addition, the extract had considerable inhibitory effects on α-glucosidase, α-amylase, and advanced glycation end-products. The matcha green tea extract significantly increased cell viability and reduced reactive oxygen species in H₂O₂- and high-glucose-treated HepG2 cells. Furthermore, in response to oleic acid-induced HepG2 cell injury, treatment with matcha green tea aqueous extract inhibited lipid accumulation and regulated the expression of inflammatory proteins such as p-JNK, p-Akt, p-GSK-3β, caspase-3, COX-2, iNOS, and TNF-α. Matcha green tea could be used as a functional material to ameliorate hepatic lipid accumulation and inflammation.

The influence of packaging methods(punched, vacuum, shrinked), mature stages(mature-green, completely ripe) and storage temperatures(5$^{\circ}C$, $25^{\circ}C$) on the shelf-life and quality were Investigated in tomatoes. Weight-loss was reduced by the treatment of polyethylene film packaging(vacuum>shrinked>punched) and the effect was more outstanding at 5$^{\circ}C$ than $25^{\circ}C$. The soluble solid content of completely ripe tomato was higher than mature green tomato, but acidity and firmness were lower. Soluble solid contents increased in the begining and decreased after that. Acidity and firmness de creased gradually during the storage. The decrease of acidity and firmness in mature-green tomato was lower than completely ripe one, at 5$^{\circ}C$ than $25^{\circ}C$ and shrinked packaging than non packaging. The shelf-life of mature-green tomato in shrinker packaging was longest, 17 days at $25^{\circ}C$ and 21 days at 5$^{\circ}C$.
