Jeonju Hanok Village, residents inhabit,.is not a Folk Village built for tourist but a town begun from the late of Joseon Dynasty. Conservation and Improvement Project of Jeonju Hanok Village should focus on not only the conservation of Hanok and tourism assets but also the improvement of the quality of resident's life. This study is an actual analysis on the residential satisfaction of residents more than the seeming evaluation of Conservation and Improvement Project of Jeonju Hanok Village. By analysis result, Conservation and Improvement Project of Jeonju Hanok Village has stability and good effects as the residence and ease resident's inconvenience.

Background : To select plant resources of the possibility of development as a natural antioxidant, the antioxidant activities including total polyphenol content (TPC), 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), 2,2-diphenyl-1-picryl-hydrazil (DPPH), ferric reducing antioxidant power (FRAP) and reducing power (RP) of perilla accessions collected from South Korea were conducted. Method and Results : A total of 18 perilla accessions by regions were selected. Two grams of dried perilla leaves were extracted with 85% ethanol and used for analysis of antioxidant activity. Antioxidant activity value was measured in a spectrophotometer. Perilla extracts showed variation in TPC ranging from 30.87 to 92.66 ㎍ GAE ㎎-1 dw. ABTS, DPPH, FRAP and RP ranged from 6.83 to 38.64 ㎍ Trolox ㎎-1 dw, 0.63 to 8.62 ㎍ ASC ㎎-1 dw, 5.05 to 17.57 ㎍ ASC ㎎-1 dw, and 4.52 to 35.69 ㎍ ASC ㎎-1 dw, respectively. TPC was high in perilla leaves of Gyeongsang-do, but other antioxidant activities were high in perilla leaves of Chungcheong-do. Cluster analysis based on antioxidant acitivities of 18 perilla accessions consist of group Ⅰ (3 accessions), Ⅱ (2 accessions), Ⅲ (5 accessions) and Ⅳ (8 accessions). Group Ⅱ characterized as higher antioxidant activities than other groups. Principal component analysis (PCA) based on antioxidant data revealed that the first two principal components (PC1 and PC2) together explained 97.78 % total variation. Conclusion : IT242410 and IT235354 of group Ⅱ showed high antioxidant activity. These resources will be useful for developing natural antioxidants.

BACKGROUND: Carotenoids which are a major source of vitamin A are contributed to have great potential role in anti-carcinogenic effects and eyesight. Carotenoids which can not synthesize in human body are required for food supply. The objectives of this study are to investigate compositions and contents of pumpkin (Cucurbita spp.) germplasms based on their pulp color. METHODS AND RESULTS: Carotenoids were extracted with 0.2% ascorbic acid in ethanol and saponified with 80% potassium hydroxide. Insoluble compounds were extracted into hexane. A total of nine carotenoids (three xanthophylls and six carotenes) were identified from pumpkin germplasms using HPLC equipped with photodiode array detector (450 nm). Especially, lutein and β-carotenes were major compound in germplasms. Among isomers of β-carotene, all-trans-β-carotene (16-27% of total carotenoids) was predominant compositions. Themean of total carotenoid contents was showed as brown (286.1 mg/100 g dw) > dark green (217.0) > orange (153.4) > primrose (85.8) > dark yellow (80.3). On the basis of carotenoid information, PLS-DA score plots showed different patterns by cluster in pumpkin germplasms. It was considered that these differences of phenotype were relative closely to genotype. CONCLUSION: This study indicated that dark color of pumpkin pulp was presented in high-level of biological pigments. It may contribute to develop potentially beneficial functional food ingredients.

This study is to raise the utilization of genetic resources of wheat (Triticum aestivum L.) landrace from East Asia (Korea, Japan, and China) by evaluating genetic variation related to end use quality concerned to bread making quality and early maturity, two very important characteristics of Korean wheat cropping system. To clarify the allelic variation of Glu-1 loci which decides HMW glutenin subunit composition, SDS-PAGE and DNA marker analysis were conducted by using 485 East Asian landrace wheat accessions in National Agrobiodiversity Center, RDA and NIAS genebank. And useful accessions getting full mark of glu-1 score and early maturity were selected to enhance the utilization of genetic resources to Korean wheat breeding. In this study, wheats from China showed the distinct characteristic. Whereas Glu-A1c (null) and Glu-B1b (7+8) allele are the most frequent in Korean and Japanese accessions, Glu-A1a (2*) and Glu-B1c (7*+9) are the most in Chinese accessions. When it comes to unique composition, Glu-B1f (13+16) and Glu-D1e (2+10) subunits are only in Chinese resources. Glu-B1d (6+8), Glu-B1e (20), Glu-D1b (7+8), and Glu-D1c (4+1) subunits are only in Korean resources. The accessions from China also has high PIC value (0.53) compared to ones from Korea (0.35) and Japan (0.35). Grouping by UPGMA analysis of combination of Glu-1 allele, most accessions from Korea and Japan are in the same group, but most Chinese ones were distinguished as the distinctive group. The evaluation of bread baking quality by Glu-1 scoring system, 26 accessions got full marks. Among them, 16 accessions from China were also matured before early June, suitable to Korean cropping system. Especially, 3 accessions (K151847, K151865, K151962) had very early maturity, matured in late May. These genetic resources, having good gluten composition and early maturity, are expected to widely be used for Korean wheat breeding.
