This study was aimed at giving help to the people intending to change their own hair color design and also providing the guide line to the cosmetic circles for developing new hair color design and promoting sales by statistically analyzing seasonal changes of hair colors puplished on women's magazines(Vogue Korea, Estetica Korea, Woman Chosun, Ce.ci) from 2003 to 2006. The researching methods were as follows; (1) hair colors published on women's magazines from september 2003 to August 2006 were measured by N.C.S. color reader(4 magazines $\times$10 main hair colors/magazine $\times$ 12 months $\times$ 3 years = 1,440 colors). (2) N.C.S. tone is made of percentage, so measured values and chromas were statistically analyzed by mean, standard deviation, and seasonal deferences were statistically analyzed by t-test and specified on high significant values. But hues were not made of percentage, so these were statistically analyzed by cross tabulation analysis, $x^2$ -test and specified on high significant values. These all had been analyzed by SPSS program(ver. 11.0). The results were as follows; (1) Usually seasonal changes of hair values were significant, specially in foreign licensed magazines, and bright values appeared in S/S and dark values in F/W. (2) Seasonal changes of hair hues were significant only on foreign women's magazines. Therefore seasonal changes of korean hair colors were not significant compared by foreign hair colors because of hardness of color changes of dark black hair and hair damages by hair tints and bleaches and trends of well being and hair care. But hair color changes have been developed gradually and will developed furthermore. So korean hair cosmetic circles have to present hair color trends deferenciated by seasons. And S/S hair values have to be brignt and F/W have to be dark. And new seasonal hair hues matched by korean have to be developed and presented.

Chitosan is an environment-friendly and natural cationic polymer that can be used as a hair cosmetic additive. Healthy hair and damaged hair samples were experimented on according to treatment conditions using a water-soluble chitosan. Chitosan treated hair samples were studied on the physical and mechanical property changes. It is most effective when the water-soluble chitosan treatment was adjusted to the Neutral (pH6.8) or Acid (pH4.5). When the water soluble chitosan was treated at pH4.5, the tensile strength, tensile elongation, and elasticity of decolorized hair all increased. The virgin and damaged hair both changed into elastic and soft hair. The effect of chitosan treatment is more noticeable in the healthy hair than in the damaged hair.

Cytokeratin 19 (CK19) expressed in epidermis of skin, bulge region of hair follicle, outermost layer of outer root sheath and proximal and distal to bulge. Vimentin is a fibrous protein that localized in cytoplasm of fibroblast and forms cytoskeleton to maintain shape of cell and nucleus. In this study, CK19 and vimentin in skin were confirmed with light, fluorescence and transmission electron microscope. As a result, CK19 was localized epidermis, hair follicles, outer root sheath and nucleus of Merkel's cell. However, vimentin was localized some epidermis, dermis, hypodermis and nucleus of Merkel's cell. The role of CK19 is self-renewal and homeostasis in skin. Also, hair follicle regeneration and hair growth is known to be related. It is supposed that required of structural proteins that make up cytoskeleton is increased. Thereby, expression of CK19 is increased. It is considered that vimentin localized in order to stabilize structure of cell and cytoskeleton of fibroblasts. Also, CK19 and vimentin present in nuclei of Merkel's cell, and to act as a fibrous protein that make up end of a nerve fiber present in Merkel's cell and paracrine function of Merkel's cell.

This study was conducted to evaluate the effects of Dictyota coriacea extract and its active components such as 1,9-dihydroxycrenulide and epiloliolide on the hair growth. Treatment with D. coriacea extract and the hexane and EtOAc fractions of D. coriacea extract significantly increased the proliferation of dermal papilla cells (DPCs), a central regulator of the hair cycle. Especially, 1,9-dihydroxycrenulide and epiloliolide from D. coriacea extract, caused an increase in the DPC proliferation. When isolated rat vibrissa follicles were treated with 1,9-dihydroxycrenulide or epiloliolide for 21 d, the hair-fiber lengths for the vibrissa follicles increased. When examined the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia, the several solvent fractions of D. coriacea extract significantly decreased the 5α-reductase activity while 1,9-dihydroxycrenulide and epiloliolide scarcely inhibited 5α-reductase activity. In addition, we found that the D. coriacea extract and several solvent fractions of D. coriacea extract could not act as a K_ATP channel opener, which could be a contributory factor in the effect on hair growth. These results suggest that D. coriacea extract and 1,9-dihydroxycrenulide and epiloliolide, principals of D. coriacea, have the potential to treat alopecia via the proliferation of DPCs.

Root hair development has the potential to increase crop yields and at the same time to decrease fertilizer use, which will be required in the next 30 years to meet the demand for crop-derived commodities in a world with decreasing available natural resources. Root hair defective six (RHD6) encoding a basic helix-loop-helix transcription factor, is associated with root hair differentiation, and its roles are root hair initiation and elongation. Grass plants, rice and Brachypodium have been used as model plants to study the gene function of the root hair defective six like (RSL) subfamily which is orthologous to AtRHD6. The RSL subfamily has an identical gene function with AtRHD6 which is involved with root hair differentiation as well. Plants with longer root hairs within a species should have an improved Pi uptake efficiency; therefore, we would expect that a plant with a high Pi uptake could contribute to increasing the plant yield. We achieved increased root hair length by manipulating the RSL subfamily genes. It is expected that in these transgenic plants, the long root hairs would be sufficient to improve the Pi uptake and hence improve biomass and yield component (tiller, spikelet number, and spikelet weight) of the plant. Here, we demonstrate that Brachypodium transgenic plants overexpressing the BdRSL subfamily genes have an improved biomass and grain yield. The result of this study could be applied to important crop plants like rice.
