The purpose of this study is to comparatively examine techniques and expressive characteristics of batik by focusing on the work of DanZhai and that of ZhenNing Buyi. We collected 50 pieces of batik each from Miao and Buyi in Chinese GuiZhouSheng and then analyzed their colors and patterns. The findings show that most of Miao's batik had deep and soft tones, while that of Buyi most often had blackish tone since the number of dyes in the latter is higher than that in the former. Miao often used patterns expressing animals or animals and plants, while Buyi frequently used geometric ones. An examination of specific motifs demonstrated that butterflies, fish, and flowers were most often used by Miao, while dots, vortexes, lines, and lozenges were frequently utilized by Buyi. For expressive techniques, both Miao and Buyi commonly used simple stylized expression or complex expression combining stylized and geometric techniques. Maio's motifs were often decoratively expressed with delicate curves, while Buyi's motifs had simple structures, so pictures were neatly expressed with thick lines and wide and simple planes. For the composition of the motifs, incomplete symmetry between top and bottom and between left and right often appeared in Maio, while in Buyi complete symmetry was frequently shown.

In this study, the researcher studied the historical background and the traditional culture about dress of Bouyei People of Guizhou Province. The resuits of the study ara as follows. 1. Women's dress and adorment can be categorized into three styles. In the Zhenning, Guanling and Puding regions and northwestern areas of Guizhou Province, women usually wear blouses with overlapping necks, batik pleated skirts and long aprons. They also wear embroidered kerchiefs or turbans. In the suburbs of Guiyand City and Southwestern Guizhou Province, women like to wear blouses with buttons arranged diagonally on the front, trousers, blue or black and white check cloth kerchiefs. In the Luoping region, women wear blouses with loose sleeves and buttons arranged diagonally on the front and loose-legged trousers. 2. Men usually wear shirts with buttons down the front or arranged on the front, trousers and calottes. 3. Most of their dress materials are white and coloured handwoven, tie-dyed or batik cloth. The exquisite technique of batik and tie-dyeing has a long history, which began to become prevalent in the Song Dynasty. 4. Now, people use all kinds of techniques to make their dress and adornment, including batik, tie-dyeing, cross-stitch, brocade and embroidery, which reflect their peculiar aesthetic temperament.

Poly-carprolactone (PCL)은 생분해성 고분자로 장기간의 임상실험 결과 생체에 독성이 없으며 생체친화성이 우수한 소재로 확인되어 PLGA, PLLA 등과 더불어 조직공학 분야에서 널리 사용되고 있는 생체재료이다. 그러나 PCL은 5개의 비극성 methylene group과 1개의 극성 ester group이 반복되는 지방족의 polyester로 구조상 탄소수가 많아 소수성을 띄는 단점을 가지고 있다. 이러한 표면이 소수성인 재료의 경우, 초기 단백질 흡착능이 떨어져 세포의 부착이 느린 속도로 일어나므로 세포 분화 및 조직 재생이 더디게 일어난다. 본 연구에서는 소수성의 PCL 표면의 단백질 흡착능을 증가시키기 위해 기능성 amine group을 부착하였으며, 또한 골재생을 촉진시킬 수 있는 세포외 기질인 collagen과 osteopontin을 부착함으로써 고기능성 PCL membrane을 제조하였다. 제조된 PCL membrane은 골재생용 조직공학에의 응용을 위해 지방유래 줄기세포를 이용하여 부착능 및 골세포로의 분화능을 확인하였다. 표면 성질의 변화에 의한 세포의 부착능의 변화를 confocal microscopy을 이용하여 부착에 관여하는 단백질의 발현을 확인하였으며, collagen과 osteopontin에 의한 골세포로의 분화능을 확인하기 위해 real time PCR을 통해 골세포의 분화 표지 유전자의 발현을 비교 분석하였다.

An intensive study of the embryology of Gymnospermium microrrhynchum was conducted to provide information regarding a discussion of the phylogenetic relationships of the genus, which is yet unstudied. Our results indicated that Gymnospermium is similar to other genera of Berberidaceae in terms of its embryological features. Nevertheless, newly reported and unique features are the well-developed endothelium and the undifferentiated seed coat type. Until the study of Gymnospermium, it may have been considered to be closer to Caulophyllum and Leontice in the tribe Leonticeae. These three genera share many morphological features as well as molecular similarities, by which they are kept in the same tribe, Leonticeae. However, very little detailed embryological data regarding these genera have been published thus far. Gymnospermium was characterized according to the basic type of anther wall formation as well as its glandular tapetum, successive cytokinesis in the microspore mother cell, two-celled mature pollen grains, anatropous and crassinucellate ovules with a nucellar cap, well-developed endothelium, its Polygonum type of embryo sac formation, its nuclear type of endosperm formation, and its undifferentiated seed coat type. In comparison with Nandina, there are many differences, such as the dehiscence of the anther, the cytokinesis in the microspore mother cells, the shape of the megaspore dyad, and the seed characteristics. Although we had no available detailed embryological information regarding Caulophyllum and Leontice, which are genera that are more closely related to Gymnospermium, we could deduce from the phylogenetic relationship that Gymnospermium, Caulophyllum, and Leontice are more closely related to each other than other genera of Berberidaceae on the basis of the seed characteristics.
