Traumatic hip dislocation associated with ipsilateral femur shaft fracture is a very rare injury and often results from high velocity injury such as traffic accidents or fall from a height 1.2). This combined injury was first documented by Sir Ashley Cooper in 1823. Wiltberger, Mitchell and Hedrick estimated its incidence at one out of 100,000 cases of fractured femoral shaft 1.3). Until 1978 there have been only 3 cases were reported of anterior hip dislocation with ipsilateral femoral shaft fracture in the literature 1.2) We have recently had the opportunity to manage the patient with anterior hip dislocation with ipsilateral femoral shaft segmental fracture and contralateral acetabular fracture.
The operative treatment of displaced acetabuilar fracture has become the preferred method than conservative treatment. Displaced acetabular fracture occurs primarily in young adult involved in high energy trauma and it can lead to some degree of permanent disability. The aim of treatment' must be the restoration of hip function which require accurate anatomical reduction and firm fixation followed by early exercise. The complicated anatomy of the region, and unsatisfactory fixation to cancellous bone, and unnecessary wide dissection of the soft tissue for plate and screw fixation contribute to clinical end results of varying success. The wire loop which was previously reported by our department as a successful method of fixation has now been developed to cable fixation that can be easily adjusted to the irregutar surface of acetabulum and get more firm fixation. A clinical anaiysis was performed on 14 patients with displaced unstable acetabular fracture who had been fixed by cable and followed for minimum 1 year period at our department from June 1993 to June 1994. The results were follows; l. According to Letorunel's classification, there were most common (9 cases:64.4%) in both column fracture, 3 cases(21.4%) in T shaped fracture, 1 case(7.l%) in transverse fracture. and I case(7.1%) in transverse and posterior wall fracture. 2. The satisfactory result was achieved in 12 cases(85.7%) on clinical grade and l2 cases(85,7%) on radiographic grade according to Epstein criteria. 3. The complication were developed in 3 cases(21.4%) out of 14 cases, such as posttraumatic arthritis in 2 cases and tansient sciatic nerve palsy in 1 case. 4. Cable fixation provides a more secure and easy fixation and require a narrower exposure than a plate fixation.
Although 90% of fresh carpal scaphoid fracture heals with adequate treatment, the rate of non-union is higher in untreated or misdiagnosed at the time of injury leading to carpal collapse and degenerative arthritis. We have treated these non-unions by modified Matti-Russe technique and all cases showed uneventful healing, but range of motion of the wrist joint decreased in some cases. We studied 18 patients of non-union of the carpal scaphoid treated modified Matti-Russe technique from November, 1988 to December, 1992 and the results were as follows: 1. Among the 18 patients, the ratio of male and female was 16:2, and mean age was 23.0 years old. 2. Dominant hand was involved in 14 cases. 3. The fracture was most commonly situated at the waist of the scaphoid. 4. Bony union was obtained in all cases and the average time to radiological union was 18.0 weeks. 5. According to Maudsley's assessment, the results revealed as 7 cases of excellent, 9 cases of good and 2 cases of fair.
Thirty-one posterior fracture-dislocations of hip with fracture of acetabulum were followed from 6 months to 84 months(average, 23.3 months). The patients' ages ranged from 19 to 58 years(average, 35.4 years). All had primary attempt at closed reduction with subsequent open reduction. Satisfactory results were obtained in 87 % of all patients. Complications included partial sciatic nerve palsy(1 case), myositis ossificans(2 cases), osteoarthritis(3 case), recurrent dislocation(1 case) and infections(2 cases). This survey was undertaken to assess the results of a certain method of treament, and in the hope of contributing further information on this subject.
흑미분말 소프트 쿠키의 제과 적성을 파악하고자 쿠키 제조시 흑미 분말 첨가량을 3%, 6%, 9% 첨가하여 제조한 후 쿠키의 물리적 관능적 특성을 평가하였다. 흑미 분말 쿠키의 비체적은 대조구와 첨가구 사이에 유의차가 보이지 않았으며 반죽 내 수분함량에 의해 결정되는 퍼짐성은 첨가량이 증가할수록 낮은 값을 나타내었다. 색도 측정결과 첨가량이 증가할수록 L값은 감소하였으며, a값과 b값은 증가하였다. 특히 a값은 시료 간 유의차가 크게 나타났다. 관능검사 결과 쿠키가 맛, 풍미, 색깔, 조직감 등에서 흑미 분말의 첨가량이 증가할수록 높은 값을 나타내었으며 전체적 수용도에서 6% 첨가구에서 가장 높은 선호도를 나타내었다. This study was carried out to investigate the influence of black rice powder addition on quality attributes of cookies. The cookies was made with various black rice powder concentration(3%, 6%, and 9%). The specific volume of cookies didn't show significant difference, and the width determined by the water content in the dough was decreased with increasing content of black rice powder. The L value in the cookies was significantly the largest value in the control group. The a and b values were the highest in the 9% substituted sample group. According to the sensory evaluation of cookies, the scores of color, flavor, and texture were raised by the addition of black rice powder. Overall acceptance of 6% cookies showed higher value than that of the 3% and 9%.
In the fracture mechanics, the determination of the stress intensity factor is very important for the prediction of material fracture. In this paper in order to determine mixed mode stress intensity K_Ⅰ and K_Ⅱ from photoelastic isochromatic fringes near the slant crack tip subjected to pure bending moment, over deterministic method by computer is used. Above method accounts for the effect of the far field stress σ_oχ Determined value from this method is compared with the Wilson's value obtained by boundary collocation method. From this experimental results, the significant advantage of over deterministic method could be confirmed.
