From August, 1986 to December, 1989, mitral valve replacement was performed in 93 patients. Of the valve implanted, 42 were Duromedics, 35 St. Jude Medical, 15 Carpenter-Edwards and 1 Ionescu-Shiley. The hospital mortality rate was 3.2%[3 patients] and the late mortality rate was 4.3% [4 patients]. The causes of hospital death were LV rupture in 1, renal failure in 1 and hypoxic brain damage in l. The causes of late death were congestive heart failure in 1 and sudden death in 3. Follow-up was done on 78 surviving patients; mean follow-up period was 29.22$\pm$9.09 months. The actual survival rate was 91.8% at 4 years. We concluded, therefore, that good clinical results could be achieved with mitral valve replacement in short-term follow-up, and long-term follow-up is also necessary.

The experimental studies for the artificial reef (AFR) subsidence characteristics in the unsteady flow field and in the unsteady flow-wave field were carried out. The difference of scou $r_sidence characteristics between in the steady flow field and in the unsteady flow field wad discussed and also the long-term subsidence characteristics in the unsteady flow field were investigated. AFR subsidence characteristics was discussed with Keulegan - Carpenter number(KC), Reynolds number (Re),. Shields number (Sn) and dimensionless time (t/Tt). And the difference of subsidence characteristics between in the unsteady flow and in the unsteady flow-wave field was discussed.ed.

Working memory is the term used to refer to the mental workplace in which information can be temporarily stored and manipulated during complex everyday activities such as understanding language. The studies on language and working memory are based on Baddeley's phonological working memory and Daneman and Carpenter's functional working memory. This article reviews two working memory models and the studies on language and working memory based on each model. These are described in the implication of working memory in language development and specific language impairment-evaluation and treatment.

한 제품의 구성 부품 수가 증가함에 따라 조립/분해 순서의 방법수는 기하급수적으로 증가한다. 또한 이 순서의 선택에 의하여 조립/분해의 효율성이 결정된다. 본 논문에서는 조립제품의 조립순서(Assembly Sequence)와 특정부품의 효율적 교체(Part Replacement)를 위한 분해순서(Disassembly sequence)에 관한 새로운 Algorithm들을 다음 3가지 경우를 통하여 소개한다 : 1) Full Assembly/Disassembly, 2) Part Replacement by Individual Disassembly, 그리고 3) Part Replacement by Group Disassembly. 이들 Algorithm들은 'Freedom and Interference Space'라는 새로운 개념으로부터 유도되며, Group Disassembly는 Carpenter's Approach를 통하여 실현된다. 이 논문에서 소개되는 Algorithm들은 조립/분해순서와 함께 조립/분해 방향도 제시하는데 비교적 복잡한 예를 통하여 이들을 실현함으로써 실제 제품 Design에의 활용 가능성을 보여준다.

The solitary wasp genus Phimenes (Hymenoptera: Vespidae: Eumeninae) was reported to occur in Vietnam by , represented by one taxon, Phimenes flavopictus continentalis (Zimmermann), which was synonymized under nominotypical Phimenes flavopictus by . A note on gender of this genus is made in the text. One more species, Phimenes indosinensis is recorded in this study from Dak Lak in the southern and Son La in the northwestern parts of Vietnam for the first time. Detailed descriptions of the female and male of the latter are provided with figures. A key to the two species from Vietnam is also provided.

A circular cylinder is oscillated in th otherwise quiescent viscous fluid. Numerical analysis performed for this problem by using the fourth-order Runge-kutta method for the unsteady Navier-stokes equations. For K(Kelegan-Carpenter''s No.)=5, the flow developed symmetrically, while for K=10, it revealed random patterns. The coefficient of the rms force is overestimated by 20-30% compared with the experimental result.

From August, 1986 to December, 1993, mitral valve replacement was performed in 178 patients. Of the valve implanted, 114 were St.Jude Medical, 47 Duromedics, 16 Carpenter-Edward and 1 Ionesc-Shiley. The hospital mortality rate was 2.8%[5 patients and the late mortality rate was 7.5%[13 patients . The causes of hospital death were LV rupture in 1, renal failure in 1, cardiac tamponade in 1, valve malfunction in 1 and hypoxic brain damage in 1. The causes of late death were sudden death in 6, congestive heart failure in 4, brain ischemic injury in 3. Follow-up was done on 155 surviving patients : mean follow-up period was 50.94$\pm$8.04 months. The actual survival rate was 88.2% at 8 years. We concluded, therefore, that good clinical results could be achieved with mitral valve replacement in mid-term follow-up, and long-term follow-up is also necessary.

In the course of the study program of benthic invertebrates of the coastal shelves of Korean Peninsula, the shallow -water chitons (Mollusca : Polyplacophora) are studied based on the collections of the Korea Ocean Research and Development Insitute made between 1980 and 1983. A total of sixteen species belonging to the Orders Lepidopleurina and Ischnochitonina , are now recognized from Korean waters,of which the following two species are newly recorded ; Leptochiton (Leptochiton ) rugatus (Carpenter in Pilsbry), and Mopalia schrencki Thiele. Illustrations, description and complte synonymies are provided for each of them.

According to the 17th century palace construction documents, head artisans were called Pyunsoo. In one building constructions, not only carpenters but also masons, plasterers and painters had their own head, Pyunsoos. This meant that Moksoo-Pyunsoo, head carpenter, could not manage the whole design of the building. Moreover, in many cases, selecting and laying the site of the building were determined by the geomancers. Under those working conditions, Moksoo-Pyunsoo could only have charge of designing the wooden parts, such as structural forms or detailed carvings. The documents showed that some dominent carpenters, like Kwak Ki Jong or Lee Choon Bong, had taken on the post of Moksoo-Pyunsoo in almost every palace constructions, especially inner palace buildings. Form the fact that the same carpenters had worked continuosly, it can be presumed that there would have many resemblance of structural forms or carvings among those inner palace buildings.
