중간 세척이 컬 웨이브 형성과 모발 손상에 미치는 영향
문순주,김민정 한국패션뷰티학회 2006 한국패션뷰티학회지 Vol.4 No.3
Perm is one the of the most common thing in a beauty salon like hair-cut and hair perm needs processing solutions which is chemical substances. Those chemical substances damage the hair cuticle. Damaged hair cuticles with mistakes of perm will follow with the next performance and it will cause more damage to hair. As damage of hair cuticle become worse, it is harder to recover the hair cuticle like before. Therefore, this study shows that plain rinse is the way to reduce the damage of hair cuticle with perm as much as possible. With experiments, I suggest the right way to do plain rinse to satisfy customers' demand and reduce the damage. During the research, I figured that plain rinse with the knowledge, structure of hair cuticle, principle of perm and plain rinse, is very needed. The hair with plain rinse have more elastic curl and have less scales which came off from hair cuticle than the hair without plain rinse. This experiment concludes that hairdresser has to figure out about the time, temperature and type of water depends on the degree of damaged hair of customers. In order to perm, there is no way to not to use chemical substances to perm. Therefore, hairdresser has to choose suitable processing solutions and right steps, and as this is the age of 'well-being' boom, hairdresser must try to keep the healthy hair. Consequently, in order to meet the demands and conditions of customers, hairdresser needs to find the right method to do plain rinse and use the method in perm.
Nonylphenol이 넙치, Paralichthys olivaceus의 생식소 발달과 성장에 미치는 영향

Effects of nonylphenol (NP) on gonadal development and growth of olive flounder, Paralichthys olivaceus were investigated. NP treatment was carried out to fry fish (during 55 to 64 days after hatching) using oral adminstration at nominal NP concentrations of 50, 100 and 150 ㎍/g BW. Gonad before NP treatment was sexually undifferentiated as observed with mostly gonia cells, At 159 days after hatching, ovarian lamella of ovary were filled with oogonia and perinucleolus oocytes. On the other hand, testicular lobules of the testis were occupied by spermatogonia, spermatocytes and spermatids. Histological observation of ovary and testis development was any different between the control and NP treated groups. However, growth was significantly increased in NP treated groups than control groups (P<0.05). These results considerate that NP has any effect for sex differentiation and gonadal development, but act for early growth in olive flounder.

Effects on nonylphenol (NP) treatment on early development of fertilized eggs and survival of larvae in olive flounder, Paralichthys olivaceus were investigated. Fertilized eggs and hatched larvae were exposed to aqueous solutions of NP at nominal concentrations of 50, 100, 150 and 200 ㎍/L. In the control Ⅰ and Ⅱ (methanol-carrier control) groups, the hatchability of fertilized eggs were 90.7±7.02 and 90.0±5.29% (P< 0.05), respectively. However, treatments of NP concentrations at 50, 100, 150 and 200 ㎍/L were reduced to 78.7±4.16, 46.0±9.17, 48.0±3.46 and 33.3±11.02% (P<0.05), respectively. The time to hatching of fertilized eggs was delayed in high-dose NP treatment groups rather than control groups. Fertilized eggs of NP immersed group could not hatch normally, and also vertebra of the larvae observed as abnormal shape. Cumulative mortality of hatched larvae after 26 hr NP treatment was 38.3, 78.3, 88.3 and 100% in NP 50, 100, 150 and 200 ㎍/L treatment groups, respectively. Whereas, control Ⅰ and Ⅱ were 11.7, 163%(P<0.05). Hatched larvae showed most death at the embryonic development stage with abnormalities. These results suggest that NP treatment in fertilized eggs and larvae was inhibited as normally development for fertilized egg and growing of larvae.
