Ex-Fi-Re 외고정 기구를 이용한 경골 골절의 치료
김대익,최창욱,나수균 대한골절학회 1995 대한골절학회지 Vol.8 No.2
Since Malgaigne described a external fixators in 1853, it were widely used for open and communited fractures. Modem external fixators such as modified Hoffman, Denham and orthofix external fixators are commonly applied because it could obtain rigid fixation and compression of fracture site. Most of external fixators used only as a fixator after reduction, however new external tixator(Ex-F- Re) by Osteo is consists of two units, which are the correction and fixation units. This device is possible to manipulate fracture fragments under the complete control of stability and to obtain more rigid fixation and compression of fracture site. Among the l6 cases of tibial fractures treated with Ex-Fi-Re external tixator device from June 1992 to June l993, 14 cases had minimum 1 year follow up and the following results were obtained. l. Among 14 cases, 7 were open fractures, 4 were closed periarticular communited fractures and 3 were infected nonunion of tibia. 2. Among 1l cases of fracture and 3 cases of infected nonunion, nonunion was happened in each one case. 3. Average bony union period was 24.4 weeks in fracture group and 44 weeks in infected nonunion group. 4. Ex-Fi-Re external fixator was very rigid fixator, easy to use, and possible to manipulate fracture fragments under the complete control of stability.

This paper offers a novel explanation in terms of the category specification parameter to the well-known Rich Agreement Hypothesis (RAH) that “rich”agreement causes V-to-I movement. In this paper we propose a new way of explaining the RAH by the so-called “category specification parameter” which states that T and V are specified or are not specified to category in syntax. In rich agreement languages, the finite verb which is merged as an inflected form has to move to T because T, which is specified to category, requires a full lexical category to be merged. On the other hand, in poor agreement languages like English the finite verb merged as a root in syntax cannot move to T because T is not specified to category. Thus it is concluded that the RAH does not have to be stipulated but can be derived from the category specification parameter in syntax. (Younsan University) .
고장위치 검출 가능한 BIST용 패턴 발생 회로의 설계
김대익,정진태,이창기,전병실 한국통신학회 1993 韓國通信學會論文誌 Vol.18 No.10
In this paper, we design a pattern generator and a fault position detector to implement the proposed fault test algorithms which are Column Weight Sensitive Fault (CWSF) test algorithm and bit line decoder fault test algorithm for performing the Built-In Self Test(BIST) in RAM. A pattern generator consists of an address generator and a data generator. An address generator is divided into a row address generator for effective address and a column address generator for sequential and parallel addresses. A fault position detector is designed to determine whether full occurred or not and to find the position of the fault. We verify the implemented circuits by the simulation. 본 논문에서는 RAM의 Built-In Self Test(BIST)를 수행하기 위하여 제안되었던 Column Weight Sensitive Fault(CWSF) 테스트 알고리즘과 비트라인 디코더 고장 테스터 알고리즘에 적합한 패턴발생회로와 고장위치 검출기를 설계하였다. 패턴발생 회로는 어드레스 발생부와 데이터 발생부로 구성되었다. 또한 어드레스 발생부는 실효 어드레스를 위한 행 어드레스 발생부와 순차 및 병렬 어드레스를 위한 열 어드레스 발생부로 나누어져 있다. 고장위치 검출기는 고장발생의 유, 무와 그 위치를 찾기위해 구성되었다. 설계한 회로들의 검증을 위하여 각 부분 및 전체적인 시뮬레이션을 통하여 동작을 확인하였다.
Effect of Phellinus baumii-Biotransformed Soybean Powder on Lipid Metabolism in Rats
김대익,김길수,강지혁,김혜정 한국식품영양과학회 2013 Preventive Nutrition and Food Science Vol.18 No.2
In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were 149.28 μg/g and 364.31 μg/g, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (P<0.05). Total serum levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, and atherogenic index ratio in the 10 or 20 BTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system.
