Various growth models were each fitted onto the data sets in an attempt to determine which growth models achieved the best forecasts for differing types of growth data. Of six such models studied, some models do significantly better than others in predicting future levels of growth. It is recommened that Weibull and the Gompertz growth curve be considered along with Pearl model by those industries presently considering the implementation of substitution analysis in their life analysis. In the early stage of growth, linear estimation should suffice to give reasonable forecasts. In the latter stage, however, as more data become availavle, nonlinear estimation should be used.

Spinal subarachnoid hemorrhage (SAH) due to solitary spinal aneurysm is extremely rare. A 45-year-old female patient visited the emergency department with severe headache and back pain. Imaging studies showed cerebral SAH in parietal lobe and spinal SAH in thoracolumbar level. Spinal angiography revealed a small pearl and string-like aneurysm of the Adamkiewicz artery at the T12 level. One month after onset, her back pain aggravated, and follow-up imaging study showed arachnoiditis. Two months after onset, her symptoms improved, and follow-up imaging study showed resolution of SAH. The present case of spinal SAH due to rupture of dissecting aneurysm of the Adamkiewicz artery underwent subsequent spontaneous resolution, indicating that the wait-and-see strategy may provide adequate treatment option.

A thermostable xylanase from Thermotoga maritima (Xyn B) cleaves several pNP-glycosides of monosaccharides. We found that the initial product of the cleavage of pNP-xyloside (pNP-Xy1) was a disaccharide, not xylose, indicating that xylosyl unit of pNP-Xyl was transglycosylated to another pNP-Xyl. We determined that the disaccharide was xylobiose which has the linkage of the ${\beta}$ 1-4, and described the reaction mechanism of the Xyn B. Also, we produced the several pNP-glycosides and propyl-disaccharides from the transglycosylation of Xyn B with varial glycosides and/or 1-propanol. All reaction products were purified by column chromatography (Toyo-pearl HW-40C, 45 cm${\times}$2.5 cm or 45 cm ${\times}$ 2.5 cm${\times}$ 2). The isolated products were analyzed by means of 1D and 2D NMR.

This study was conducted on the costume of the 6 minorities dwelling in Guizhou Province of China. The result of the study is summarized as follows. As Guizhou Province yields much silver, most of the minorities used silver ornaments a lot and dyed their garments by using indigo extracted from plants that grow in the area. The headdress was of style that for both men and women a long cloth is wound around a head in various ways. In some cases, women used cow's horn, pearl and silver ornaments. Most wore a short upper garment such as blouses with overlapping necks or blouses with diagonal on the front, and as a lower garment men and women wore trousers and skirts, respectively. As a way of ornament, embroidering, wax printing and weaving were commonly used, but pattern and color used in the ornament varied depending on the individual minorities.

The objective of this research is to examine the fashion styles of Choe Seung-Hee (1911-1969), modern woman and dancer of Korea, through her life and activities. From such theoretical and empirical studies, three aesthetic characteristics of South Korea's modern woman Choe Seung-Hee's fashion styles could be deduced. Based on the three deduced styles of modern elegance, futuristic avant-garde and mystical Asian aesthetics, "Pearl of Asia" was selected as the main theme. The result is that the fashion styles of Choe Seung-Hee is not simply that of an individual modern woman and a dancer who lived in the early 20th century but is a meaningful symbol of Korea's modern women.

The flavonoids from plants is very widly used as natural dye for food and medicine etc. In this study, red pine which is widespread in Korea was studied to find new chemicals which may use as raw material for the special purpose. The fIavonoids of red pine bark were separated with Sephadex LH-20 and Toyo pearl HW-40F as packed materials and the structure of separated f1avonoids was determined by $^1H$-and $^{13}C$-NMR spectroscopy. The (+) catechin which is widespread in nature and dihydroquercetin-3'-0-${\beta}$-galactoside were found in red pine bark. The dihydroquercetin-3'-0-${\beta}$-galactoside is newly found in this species.

21C, the age of culture, has the effects on the whole aspects in society with its cultural features, and the social changes become the foundation to create the new culture. The W generation, which accounts for Woman, World, Well-being, and Web, etc, leads the trend as 'a new group of powerful consumers' of establishing a new pattern. The W generation prefers psychidelic make-up using pearl through the cyber space, a space for communication like the N generation. In addition, through the Internet, leading the society of fusion or hybrid, with gender and age broken-up, the feminine as well as kidult-like make-up has emerged. On the other hand, with the influence of well-being on the whole society, well-looking appears outside, and lohas inside.

Two 53-day-old broiler chickens were condemned due to multiple cutaneous nodular masses at slaughter house. Grossly, variable sized round masses were scattered in the abdomen and pelvis. Some of them were large and fused each other. Center of large fused nodules were ulcerated. Histopathologically, tumor masses consisted of multiple cords or masses of epidermal cells. Some of \ulcornerem contained central conoentric lamella of keratin (cancer pearl). From these results, these cases were diagnosed as cutaneous squamous cell carcinoma. This is the first report of cutaneous squamous cell carcinoma occurred in broiler chickens in Korea.

"62번 보다는 좀 어둡게" 또는 "62번과 65번 사이 정도로"라는 이러한 지시들이 만족스러운 결과를 가져오는가? "선생님, 제 앞니가 이젠 너무 희고 자연스럽지 않아요. 남들이 보면 해 넣은건지 금방 알아요." Porcelain fused to metal crown은 그 심미적 장점 때문에 전치부 수복에 있어 사용이 보편화되어 왔다. 하지만 두께의 제한과 세련되지 못한 일률적인 수복물은 일반적으로 너무 밝고 흰(높은 명도와 낮은 채도) 까닭에 인공적인 것을 쉽게 식별할 수 있으며, 환자들도 하여금 보다 개성화가 요구되어 오고 있다. 이러한 심미적 요구와 함께 최근 우수한 심미성과 높은 강도의 도재전장관들, 즉 Dircor이나 Cera Pearl, Alumina 또는 Magnesia core porcelain등이 연구 개발되어 왔다. 도재 축성술에 있어서도 내장된 첨색효과(internal characterization)나 다층축성법(layer build up)등 많은 방법들이 발전되어 왔다. 자연스러운 도재관을 재현하여 주기 위해서는 먼저 자연치아의 색조에 관한 치과의사의 충분한 인식과 판단이 앞서야 한다. 인식된 색조에 대한 정보가 체계적으로 기록되어 기공사에게 전달되고 재현되어야 한다.
