The focus of design in the contemporary point of view has changed from the improvement in production efficiency for profitability and in styling for sales promotion to human-oriented design. Human-centered design has developed into design which includes social and ethical responsibility and values. With tradition and culture as a base the principles of markets and capital are incorporated as well. Such current design is the outcome of design which honors social values represented based on culture acquired from individuals and society and the the responsibility of the designer who provides it. For the realization of social values in design, it should be considered along with the influence of design on society, this study presented the following cases: First, human-oriented design for those who are isolated, but should not be ignored; Second, cultural-oriented design which makes a contribution to local conditions; and third, usability-oriented design which replaces familiar ideas with new paradigms. This study presented the function and meaning of design in terms of purpose and the methods to solve social and human problems using design. Further studies should deal with the realization and extension of social values through design.

In the present study, characterization of fermented carrot juice by Bifidobacterium was performed. When inoculated at the level of $10^6\;CFU/mL$ with various Bifidobacterium strains, cell growth of B. longum, B. adolescentis and B. infantis reached more than $10^8\;CFU/mL$. On the other hand, B. bifidum strains reached less than $10^8\;CFU/mL$. Compared with carrot, grape juice did not allow the growth of Bifidobacterium, while peach juice and orange juice were as good as carrot for the growth of Bifidobacterium. On mixed culture with Lactobacillus, growth of Bifidobacterium decreased and cell death rate increased considerably. On panel test, Bifidobacterium cultured-carrot juice showed high score on sensory test than non-fermented carrot. Therefore, fermentation may lead to the quality improvement of carrot juice by combining health-promoting effect of Bifidobacterium and high nutrition value of carrot.

Twenty one phenylacetylshikonin analogues were synthesized from various subsitituted phenyl acetic acids and their cytotoxicity values against A549, K562 and L1210 cell lines and antitumor action in mice bearing S-180 cells were measured. All of phenylacetylshikonin analogues expressed a potent cytotoxicity $(ED_{50}, 0.1-1.80{\mu}g/ml)$ against L1210 and K562 cells. L1210 cells were the most sensitive to shikonin analogues among these cells. Except 4-methosyphenylacetylshikonin $(0.098 {\mu}g/ml)$, and a-acetoxyphenylacetylshikonin $(0.10 {\mu}g/ml)$, all other shikonin derivatives sshowed higher $ED_{50}$ values than phenylacetylshikonin $(0.13{\mu}g/ml)$, in L1210. In K562 cell, a-substitution of phenylacetylshikonin $(0.1{\mu}g/ml)$, while other subsitutions increased it slightly; 4-methoxyphenylacetylshikonin $(0.033{\mu}g/ml)$ showed a exceptionally good cytotoxicity against K562 cell. 4-Halogenation tended to decrease the cytotoxic effect on L1210 cells, while it enhanced the effect on K562; 4-bromophenylacetyl $$[ED_{50};(L1210)=1.76{\mu}g/ml, ;ED_{50};(K 562)=0.32 {\mu}g/ml]$$ and 4-chlorophenylacetyl shikonin $$[ED_{50};(L1210)=1.64 {\mu}g/ml, ;ED_{50};(K562)=0.32 {\mu}g/ml]$$. In contrast, A549 cells were much less sensitive to these shikonin analogues which showed $ED_{50}$ values of$1.5-1.35 {\mu}g/ml)$.Most of phenylacetylshikonin derivatives showed good antitumor activity in mice bearing S-180 cells. a-A-cetoxyphenylacetylshikonin and 4-dimethylaminophenylacetylshikonin showed highest T/C value (192-195%), implying that introduction of a-acetyl or of 4-dimethylamino group enhanced the antitumor activity as shown for 4-dimethylaminophenylacetylshikonin (T/C, 192%). It might be due to improvement of water solubility by dimethylamino group in the molecule.

Biochemical characteristics of 24 Pongamia pinnata genotypes (candidate plus trees) from three agroclimatic zones were estimated and molecular characterization through RAPD markers was done. Various biochemical characters viz. seed oil, total carbohydrates, protein, acid value and Iodine number recorded significant variation among different genotypes. The highest seed oil content was 41.87% while seeds of 14 genotypes recorded above average (32.11%) for the trait. Seed oil and protein content exhibited a significant positive correlation and moderate heritability. Out of the initially selected twenty-five random primers, twenty-two RAPD primers were found to be highly reproducible and produced a total of 183 loci of which 147 (80.32%) loci were polymorphic. Percentage of polymorphism varied from 44% to 100% with an average of 80.62%. High level of genetic variation was found among different genotypes of P. pinnata. Both molecular and oil content (biochemical) markers appeared useful in analyzing the extent of genetic diversity in Pongamia and the result of these analyses will help to better understand the genetic diversity and relationship among populations. Overall, the Pongamia genotypes included in the study showed a correlation with their geographical origins such that genotypes from the same region tend to have higher genetic similarity as compared to those from different regions. However, in UPGMA based Nei's analysis, some genotypes were found not to be grouped based on geographical origins possibly due to the exchange of germplasm over time between farmers across the regions. The results from oil content analyses showed that several genotypes in 'Central and Western Plateau' agroclimatic zone of Jharkhand displayed a good potential for high oil content. The study provides insight about P. pinnata populations in Jharkhand (India) and constitutes a set of useful background information that can be used as a basis for future breeding strategy and improvement of the species.

This study aims to conduct a investigation on the gusset of a Kimono sleeve to achieve excellent movability through an evaluation of its fit wearing by conducting comparative research in terms of the length of the gusset pattern according to sleeve angle, which having a great effect on the wearing and activity of the top of a Kimono sleeve. A prototype was manufactured by developing the basic Kimono sleeve based on the method of Ernestine Kopp's basic bodice pattern. The sleeve angles which was applied to the prototype pattern of the Kimono sleeve ware approximately $50^{\circ}$, $70^{\circ}$ and the gusset was diamond-shaped which has a width of 10cm and lengths of 9cm, 10cm and 11cm. As a result, in the case of $55^{\circ}$ of the sleeve angle, the angle was gradually increased as the length of gusset was extended, although, in the case of $68^{\circ}$ of the sleeve angle, there was not remarkable effects between increased gusset length and the value of the angle. This result could be analyzed that the gusset did not affect remarkably since the sufficient movability was gained with only the angle in the case of $68^{\circ}$. Also, in the results of experiment on $55^{\circ}$ angle, as 9cm, 10cm and 11cm of length of gusset commonly indicated over $70^{\circ}$ in average, it was found that the movability was obtained sufficiently in every part.
