Hamburg's development politics like "metropolis Hamburg - a growing city" demonstrates an important economic and demographic growth during 1997 to 2008. Beyond the positive factors with the idea of creative city, only selected class of people are involved in the city's active living, the others experience only gentrification. The G$\ddot{a}$ngeviertel, where the Hamburg's working class and dockworkers had lived, will be analysed as a historical important place of the gentrification since the end of the 19'century. This paper focuses on the actual Hamburg's movement of the initiatives "Komm in die G$\ddot{a}$nge" and " Right to the City", which took over the last 12 buildings of the G$\ddot{a}$ngeviertel. The G$\ddot{a}$ngeviertel Project, with the slogan "the city is neither a business nor a brand, but a community" could be an example of an alternative and sustainable solution for better living in the urban area of the Hamburg.

This study was carried out to find out the optimum method of preparation of indigo standard solution and its stability, and to investigate the indigo contents in Niram, blue dye extract, from a total of 7 indigo plants and 34 breeding lines of Persicaria tinctoria H. Gross. Proper solvent for indigo standard was dimethyl sulfoxide (DMSO), and appropriate concentration was 1 mg of indigo in 10 mL of DMSO. Absorbance value of UV/Vis Spectrophotometer at 620 nm of standard solution was changed decreasingly 12 hours after the preparation of standard solution irrespective of the storage conditions such as temperature and light. Average value of absorbance of 8-fold diluted standard solutions prepared daily during 16 days was $0.210{\pm}0.005$, indicating the powder of indigo compound was stable chemically. Calibration curve was made for quantitative analysis of indigo of 7 Niram samples, and indigo contents ranged from 0.69% to 18.76% showing relatively larger variation. Across all 34 breeding lines, the range of indigo content was from 7.9 mg to 56.4 mg per 100 g of fresh leaves, averaging 25.2 mg of indigo content and showing a 47.7% coefficient of variation.

Market available fermented indigo powders of Indian origin (FI1, FI2), Chinese origin (FC1, FC2), and raw indigo powders of Indian origin (R1, R2) were examined using TLC and HPLC analyses to investigate their pigment contents. TLC analysis gave $R_f$ values of 0.81 and 0.72 for blue and red pigments, respectively. All the powder products and the synthetic and natural indigo standards eluted at 6.9 min and 8.3 min in the HPLC chromatograms, and the peaks showed the ${\lambda}_{max}$ at 610nm and 542nm, representing indigotin and indirubin, respectively. The pigment content calculated based on the area of indigotin and indirubin peaks in the HPLC chromatograms showed that the indigotin content was higher in FC1 and FC2, while FI1 and FI2 had a higher indirubin content. The relative percentage of indirubin was the highest in R2, but the HPLC peak intensity was quite low. Despite the higher indigotin content in FC1 and FC2, cotton dyed with FI1 and FI2 (versus cotton dyed with FC1 and FC2) showed a higher blue (B) hue, the highest K/S values, and the highest antimicrobial effect.

A comparative Life Cycle Assessment (LCA) among three types of Electric Motor Unit (EMU) Interior Panel (IP) was conducted. A functional unit for comparative LCA is a weight of IP for 1 EMU. It is assumed that Manufacturing stage and its upstream processes, Use stage and End of Life (EoL) stage are included in the boundary of product system. For Use stage, the weight of IP causes electricity consumption. It is assumed that aluminum IP is recycled and the other IPs are incinerated at the EoL stage. As a comparison results, aluminum IP has much larger environmental impact (5.162pt) than others (FRP IP; 4.069pt, Phenol IP; 4.053pt) even though recycling consideration is included. The manufacturing stage of aluminum IP has relative big environmental impact (1.824pt) and this point make the most important difference from other IPs (FRP IP; 0.1617pt, Phenol IP; 0.4534pt)). Despite of large weight difference between FRP IP (888.96kg) and phenol IP (316kg), the final environmental impact result has only little difference (0.016pt, 0.39%). With this result, the EMU designer can choose IP with a consideration of the environmental performance of IP.

Rice (Oryza sativa L.), the world's most important crop, is usually classified into ssp. indica and japonica based on morpho-physiological traits. In the previous study, we have developed subspecies-specific STS markers (SS markers) to readily discriminate between indica and japonica in O. sativa. In this study, we employed SS markers to investigate the genomic inclination of worldwide collections of O. sativa. A total of 320 varieties were divided into two groups with 63 SS markers. Namely, they formed two distinctive groups, indica and japonica, as expected by their geographic origin. The population structure analysis revealed that the variability of genetic background was greater in indica than in japonica. Some of them, however, exhibited intermediate genomic inclination between indica and japonica. These results are in general agreement with the previous studies, suggesting that SS markers are powerful tools for both determination of subspecies genome and assessment of genetic diversity in rice.

In this study, NF Complex of 0%, 0.5%, 2.5%, 12.5%, and 100% was prepared by complexing and extracting Indian gooseberry, Rosa multiflora Thunberg roots, and saw palmetto fruit in a ratio of 5:1:1. The manufactured NF Complex was applied to bleached sample hair and then compared and analyzed with damaged hair. To confirm the improvement effect, tensile strength, gloss, absorbance, and brightness were measured. As a result of the measurement, the tensile strength increased. The gloss content decreased by 100%, but the remaining content increased. The change in absorbance was minimal. There was also a change in brightness, but it was minimal. It was confirmed that there is a significant difference in the average value of NF Complex, and it is judged necessary to study various ratios in the future.

Natural indigo dye was prepared by extracting from Polygonum tintorium, precipitating with calcium hydroxide, and dried. Dyeing was carried out using sodium hydrosulfite as a reducing agent for the prepared natural indigo powder. K/S value, color property, and colorfastness of dyed fabrics were investigated. Optimum dyeing conditions obtained were 60$^{\circ}C$, 20min. Regardless of indigo dye and sodium hydrosulfite concentration, Munsell hue of dyed fabrics was PB color. Compared to the dyed fabric with both sodium hydroxide and sodium hydrosulfite, those with sodium hydrosulfite only showed higher color strength(K/S value). Colorfastness of dyed fabrics showed high rating except of wash/dry cleaning fastness of silk fabrics dyed low color strength.
