  • 본 연구는 레이저, 클리퍼, 가위 등의 커트도구를 사용하여 모발절단면의 형태학적 특성을 주사전자현미경으로 관찰하였다. 레이저(razer)를 사용해서 절단된 모발의 단면은 모발 끝이 한쪽 방향으로 예리하고 뾰족하게 형성되었고 모발의 잘린 면이 얇아지면서 모발의 바깥쪽 부위로 휘어지는 것을 확인하였다. 가위(scissors)를 사용하여 절단된 모발의 횡단면은 비교적 깨끗하게 관찰되었다. 이는 가위와 사람의 손힘이 일정하게 주어짐에 따라 모발의 절단면이 찌그러지거나 눌림 현상 없이 모발형태가 변형되지 않고 절단되었기 때문인 것으로 관찰되었다. 클리퍼(clipper)를 사용해서 절단된 모발 횡단면의 큐티클층은 손상되지 않고 고르게 잘려 나갔으나 피질(cortex)은 섬유성 단백질인 거대원섬유 (macrofibril)들이 매끄럽게 잘려나가지 않고 모발단면의 중간위치에서 층이 형성되는 것으로 나타났다. 이것은 클리퍼의 날이 전기적인 힘에 의해서 고속으로 움직이면서 모발을 순간적으로 절단하면서 생기는 자국으로 나타났다.

  • A concern of safety issue for traditional herbal medicine is the possibility of some herbs containing heavy metals responsible for several cases of metal poisoning. In our previous study, the physiological levels of heavy metals, such as Cd, Cu, Hg and Pb, were examined to evaluate a potential risk in patients taking herbal medicine. In this study, the levels of 12 heavy metals, including non-metallic element, Se, were analyzed in hair and compared to the results from the previous study. In the previous study, the levels of Cd, Cu, Hg and Pb in hair showed a significantly lower odds ratio than 1. In this study, however, all metals did not show any significant odds ratio higher or lower than 1 even if 5 of 12 metals showed lower odds ratio than 1. In addition, the levels of metal concentrations, especially for Cu, Fe, Pb and Zn, exceeding the WHO reference values were observed in hair. However, any evidence for metal accumulation in hair caused by taking herbal medicines for long duration was not observed in analysis of multiple regression and odds ratio from case-control study. This result would show another possibility for a role of herbs as a non-enzymatic chelator inhibiting the gastrointestinal absorption of heavy metals.

  • 당근(Daucus carota L. var. sativa)은 세계적으로 널리 이용되는 작물 중 이며, 영양학적으로도 중요한 작물이다. 하지만, 종자 표피세포에서 생성되는 종자모는 발아를 억제하고 흡수를 저해하여 육묘에 어려움을 야기한다. 이러한 어려움을 타파하기 위해 당근 종자는 기계적인 제모작업을 거쳐 상품화 되고 있다. 이 과정에서 생산상의 여러 가지 단점들이 발생하며, 이를 보완하기 위해 단모종자 당근 품종의 육종이 필요하다. 따라서 본 연구는 단모종자 표현형 CT-ATR 615 OP 666-13개체와 장모종자 표현형 CT-ATR 615 OP 671-9개체 및 단모종자 표현형 CT-SMR 616 OP 659-1 개체와 장모종자 표현형 CT-SMR 616 OP 677-14개체 등 두 조합의 종자 cDNA library를 작성 후 EST 염기서열의 비교분석을 통해 당근 종자모 형질관련 연구에 이용하고자 하였다. 첫째로 EST 염기서열의 BlastX 결과를 바탕으로 각각의 EST를 FunCat 기능별 category로 분류하였다. 그 결과 Metabolism category와 protein folding 및 stabilization, protein binding, C-compound binding category에서 2조합 모두 동일한 유의적인 차이를 확인하였다. 두 번째로 EST 염기서열의 GO data를 바탕으로 seed trichome differentiation 및 cellulose biosynthetic process에 관련된 EST를 선발하였다. 이러한 FunCat category에서의 차이점과 GO data 분석을 통해 확인된 후보 EST 들이 당근 종자모 형성에 많은 영향을 미치는 것으로 생각된다. 마지막으로 분석된 개체 별 EST 염기서열을 바탕으로 33개의 SNP site, 741개의 SSR site를 확인하였다. 확인된 SNP 및 SSR site는 당근 종자모 형성에 관련된 분자마커 개발에 이용할 수 있음은 물론 당근의 여러 형질에 대한 연구에 활용 가능할 것으로 기대된다.

  • As a result of research, the character of the general dress-costumes from the late 17th century to the early 18th century in Genre Paintings of DuSeo Yun and YoungSeok Cho is as follows. Firstly young women wore braided hair at the back of head and married women wore hair in the style of Unjeun-mori with Gache. The length of Jeogori (Korean traditional jacket) covered waistor shortened to waist length. The width of Jeongori was suitable, because side-seam line was straight or oblique as it comes into inner line. The width of Git was enough and Mokpan-git (shape of board) and Kal-kit (shape of knife) appeared, and sometimes used other color fabric. Sleeve was narrow and ostly folded up. Chima (Korean traditional skirt) used darker color fabric than Jeogori and the width of Chima was narrow and its length was short. Sokbaji (Korean traditional underpants) shown below were narrow and its end narrower. They were barefoot or they wore Hye (Korean traditional shoes) after putting on Beoseon (Korean traditional socks). Secondly general man's hair tie a topknot (sangtu) and put on headdres, 'Bang-lip', 'Mang-geon', hairband, 'Tang-geon' on head. The length of Jeogori became shorter from the line which covered hip to the line which covered waist. The width of Jeogori was suitable and sometimes it had a slit of side-seam line. The width of Git (neckand) was wide and the length of Git was long. 'Kal-git'appeared and it used other color fabric. The shape of sleeve was straight and narrow. They folded up their sleeves. They folded up their sleeves. They folded up their slack that look like 'Jam-bang-i'and the width of slacks was not suitable, and it was narrow. Baji (Korean traditional pants) were with or without knot, worn 'Hangjeon'(ankle band). They were barefoot and wore 'Hye'or 'Jipsin'(Korean traditional straw shoes). Thirdly a person of high birth or a low-ranked official put 'Yu-geon', 'Mang-geon', 'Gat', 'Tang-geon', 'Bok-du', 'Bok-geon', 'Whi-hang'on their head on a topknot. They wore 'Po (Shim-ui, Jick-ryeong'Jung-chi-mak, Do-po, etc)'on Baji and Jeogori. 'Po'was long and wide, it knot with 'Se-jo-dae'(string belt) or 'Po-baek-dae'(band belt). It had a slit of sideline and 'Mu'which had or had not or which were hard to confirm. The shape of sleeve was straight or very wide and its length was long. The width of Baji was wide and knotted with 'Hangjeon'and wore'Beoseon'and 'Hye'. Fourthly child's hair was short or knotted to the back of the head. The length of Jeogori reached waist line and its width was wide. It had a 'Jeogori'which had s slit of sideline. The shape of sleeve was 'Tong-su'(straight), and the length of sleeve was diverse. They put 'Baeja'on 'Jeogori'. The width of Baji was not wide. They wore them straight without or with knot, 'Hangjeon'. They were barefoot or put on 'Jipsin'.

  • Objectives: Recently, thread-embedding therapy (TET) has been widely applied in Korean medicine for cosmetic purposes such as reducing skin wrinkles. An inserted thread was reported to have induced continuous stimulation, followed by support for connective tissue regeneration. However, the potential role of TET in hair-growth has not yet been reported. Methods: We designed this study to evaluate whether TET has a hair-growth-promoting effect. C57 black 6 (C57BL/6) mice were divided into three groups: normal saline-treated, minoxidil-treated, and thread-embedded groups. Normal saline or 5% minoxidil was topically sprayed on the dorsal skin of the mice once a day for 16 days. Medical threads were embedded into the dorsal skin of the mice in a single application. Hair growth activity was evaluated by using dermoscopic and microscopic observations. Sections of the dorsal skin were stained with hematoxylin and eosin. Expressions of bromodeoxyuridine (BrdU), proliferating cell nuclear antigen (PCNA), fibroblast growth factor-7 (FGF-7), and fibroblast growth factor-5 (FGF-5) were detected by using immunohistochemical staining. A reverse transcription-polymerase chain reaction (RT-PCR) analysis was adopted to measure the messenger RNA (mRNA) expressions of FGF-7 and FGF-5. Results: TET enhanced anagen development in the hair follicles of C57BL/6 mice. The expressions of BrdU and PCNA, both of which imply active cellular proliferation, were increased by using TET. Moreover, TET increased the expression of FGF-7, an anagen-inducing growth factor, while decreasing the expression of FGF-5, an anagen-cessation growth factor, both at the protein and the mRNA levels. Conclusion: TET enhanced hair re-growth in C57BL/6 mice. TET regulated the expressions of anagen-associated growth factors and activated the proliferation of hair follicular cells in depilated skin lesions. Considering its long-lasting effect, TET may be a good alternative therapeutic for the treatment of alopecia.

  • Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator. We studied skin immunological effect. collagen synthesis. cell growth and whitening effect of SANSAM extract. IN cosmetics.. SANSAM extract had skin fibroblast cell growth effect. recover damaged skin in the sun and protect fine wrinkle. Also. In hair product.. inhibits hairless, white hair.its hairless, white hair.

  • Fine structural characteristics of eggs (nits) found on the scalp hairs of Korean children were observed with scanning electron microscopy. An egg is structurally composed of four parts: the cementum, nit body, operculum, and aerophyle. The total length of an egg is about 1.5 mm. The glue secreted from the female louse completely surrounds the 1 mm hair shaft and forms the cementum. The thickness of the cementum at the end of the nit body was found to be more than 5 times the thickness at the end toward the scalp. The nit body is shaped like a goblet with a very smooth surface. The operculum and aerophyles are located at the apiculus area. In the circular operculum, there are 10 aerophyles concentrated on the side of the hair shaft surface that are shaped like a dome. Three aerophyles in the center are surrounded by 7 aerophyles. Each aerophyle is dome shaped with a diameter of $65{\mu}m$ and a respiratory pathway with a $15{\sim}25{\mu}m$ opening at the center. On the cut surface where the operculum is separated as the egg hatches, long grooves about $1{\mu}m$ thick are uniformly formed transversely. These long grooves facilitate the separation of the operculum through body expansion at the time of hatching.

  • This research analyzed the role of sex and clothing in the seventh version of elementary school textbook-Korean. Analyzed materials were described contents and illustrations or pictures in textbooks - Korean of the wholeclasses with content analysis. The followings are the summary of the results. First, the proportion of males to females is 55.6%. Second, the proportion of female's skirts to trousers is 80.6%. Third, the proportion of female's long hair style to short hair style is 61. 9%. Fourth, mother and female-teacher clothes mainly show skirts. Fifth the results compare father's working with mather's in home: fathers mainly spend the time with family and mothers mainly cook and play roles of housewife. As it was shown above, the ratio of sex in textbooks of elementary school has a tendency to be unfair. Clothing and apperearances of female don't also reflect the present actual tendency. Contents of textbooks are apt to emphasize on the traditional feminine attitudes.
