An 8 x 16-b adiabatic register file with one read port and three write port and a 4-bit counter are designed. A four-phase clock generator is also designed provide supply clocks for adiabatic circuits. All the word line and bit line charge on the capacitive interconnections is recovered to save energy. Adiabatic circuits are based on efficient charge recovery logic (ECRL) and are designed using 0.35㎛ CMOS technology. The functionality of adiabatic circuits are verified and the energy consumption of adiabatic circuits are obtained using SPICE simulation. The energy consumption is 6.67∼9.17 pJ/cycle from 10㎒ to 100㎒ operating frequencies. The proposed adiabatic circuits are useful as the building blocks of low power circuits.

이승구,송석환,이주엽,문창윤,오재찬 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목적 : 수부의 중수지 관절 탈구의 관혈적 정복이 필요했던 예에서는 정복을 방해하는 구조물에 대해 분석하고 도수 정복이 가능했던 예에서는 성별 및 탈구 형태에 따른 특성에 대해 알아보고자 하였다. 대상 및 방법 : 총 27예의 수부 중수지 관절 탁구 환자 (무지 11예, 이지 14예, 소지 2예)를 대상으로 연구하였다. 탈구된 중수지 관절의 정복을 방해하는 해부학적 구조는 수술시에 확인을 하였으며, 도수 정복이 가능하였던 예들에서도 연령과 손상된 구조물, 그리고 최종적인 임상 결과를 평균 7개월간 추시 관찰하였다. 결과 : 무지 중수지 관절의 탈구 11예 중 파열된 전방 관절낭, 수장판과 단무지 굴건의 파열을 동반한 복합 탈구가 8예 있어 관혈 정복을 시행하였으며, 2예에서만 도수 정복이 가능하였다. 관절염이 있던 1예는 관절 유합술을 시행하였다. 다른 수지의 중수지 관절의 탈구는 Kaplan의 개념에 따라 탈구를 수술 정복하였고 파열된 수장판을 복원하였으며, 1예에서 수술시 표재 중수 횡인대만의 절개와 이완으로 정복할 수 있었다. 소지 중수지 관절 탈구의 2예에서 파열된 요측 측부인대가 수술시 관찰되었고 이를 복원하여 수지의 불안정성을 예방하였다. 이들의 최종 결과는 특별한 운동 제한이나 불안정성 없이 좋은 결과를 보였다. 결론 : 적절한 국소 마취하에 도수 정복을 1~2회 시행할 수 있지만 단순 정복이 가능한 탈구가 부적절한 견인으로 정복이 불가능한 복합 탈구로 진행할 수 있다. 그리고 복합 탈구는 대부분 관혈적 정복이 필요하기 때문에, 정복 방해 구조물에 대한 충분한 이해와 적절한 조치가 필요하다. Purpose : To analyse the obstacles to prevent the reduction for dislocation of the metacarpophalangeal (MP) joints of the hand and evaluate the relationship between the sex and dislocation type in closed reduction case. Materials and Methods : Total 27 cases of MP joint dislocation of the hand (11 cases of thumb, and 14 index and 2 little finger) were reviewed retrospectively. The anatomical structures to prevent the reduction were confirmed at operation and the cases which were reduced immediately were also analysed for their ages and differences of damaged structures, and finally their complications or outcome were reviewed for average 7 months after reduction. Results : In 11 cases of thumb MP joint dislocations, the complex dorsal dislocations in which the protruded metacarpal neck was caught by buttonhole of torn anterior joint capsule, volar plate and FPB were reduced by open method in 8 cases, and closed reduction was done in 2 cases but one old case required arthrodesis. In other finger MP joint dislocations, the Kaplan's concept to prevent the reduction was confirmed. But reduction of torn volar plate and incision of transverse metacarpal ligament were sufficient to reduce the dislocation with gentle longitudinal traction during the operation. In two cases of little finger MP joint dislocation, the ruptured radial collateral ligaments were noted after open reduction and it must the repaired to prevent the finger instability later. Their overall end results were good without any significant restriction of MP joints motions and finger instabilities. Conclusion : One or two times of closed reduction with proper local anesthesia could be tried, but simple reducible dislocation can be converted to complex irreducible ones by the inappropriate traction method, and so proper reduction technique by closed or even in open way is important with the knowledge of anatomical obstacles to prevent the reduction of the metacarpophalangeal joints.

The study was carried out to investigate the effect of grass quality and climate on weight gain. Six co-operative village farms were surveged which reared Korean native and Korean cross-bred cows. The results obtained were as follows; 1. The farms examined had 66% improved pasture and a stocking rate of 0.9ha per head. 2. On all the farms, the total dry matter content of native pasture was more than that of the improved pasture. 3. In the case of native pasture the crude protein content when fertilized(12.05% cp compared to 7.87%). On the other hand, there was no difference in crude protein content between fertilized improved pasture and non-fertilized. The crude fibre content of improved and unimproved pasture decreases when fertilized. 4. Body weights during June, July, August, September and October were 347.0kg, 358.5kg, 384.5kg, 414.2kg and 421.8kg respectively. 5. The average daily weight gain on each farm was 0.89kg on Hawoen, 0.81kg on Yeong Nam, 0.71kg on Hoicheon, 0.60kg on Young Kang and 0.15kg on Oh Ra: The total weight gain of all the cows on all the farms was 76.8kg with an average daily weight gain of 0.6kg per cow.

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

There is a need to improve the efficiency of the existing sanitary treatment facilities, because the effluent standard becomes more stricter and septic sludge increased. Thus, operating processes of sanitary treatment system in M city changed with installation of additional facilities. Process modifications were as follows: Dilution water was added to the next process after primary aeration tank. Some secondary sedimentation sludge was recycled to primary aerator so that most of the organics were stabilized in primary aeration tank under automatic control of dissolved oxygen. The line of effluent from dewatering process flowing to the activated sludge tank was changed to the primary aerator. The primary sedimentation sludge line was linked to a thickener. Polymer was added to the activated sludge tank. The effluent of primary aerator and aerobic digester was recycled from the 5th to the 1st sector. As consequencies of above process modifications, the improvement of removal efficiency was achieved as BOD 54%, COD 42%, SS 61%, T-N 39%, and T-P 12%, respectively.

The chronic suppurative otitis media is one of the most common disease in the otologic field. And the works on bacterial distribution of chronic suppurative otitis media were studied by many otologist, but there is some difference. The bacteriologic study was done on 126 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Chosun University Hospital between January 1989 and December 1989 and the following conclusions were obtained. 1) In sex distribution, the male had higher incidence rate than female (M: 56.3%, F:43.7%). 2) In age distribution, 3rd decade (34.1%), 2nd decade (34.1%), were most prevalent. 3) In duration of the disease, the hightest frequence was below 5 years duration 4) Among 126 cases, 98 cases(77.8%) were unilateral (right ear was 47 cases(37.3%) and left ear was 51 cases(40.5%))and 28 cases(22.2%) were bilateral. 5) The 136 cases(88.3%) showed the positive results under culture, but 18 cases(11.7%) didn't growthed. Among 136 cases 95 cases(61.7%) had single infection and the 41 cases(26.6%) had mixed infection. 6) The most frequently isolated bacteria was staphylococcus(38 strains, 27.9%) and next were proteus(27 strains, 19.9%) and pseudomonas (22 strains, 16.2%). 7) The Staphylococcus was sensitive to cephalothin(94.7%), amikacin(78.9%) and resistant to penicaIin(63.2%). 8) The Proteus was sensitive to amikacin(92.6%), cephalothin(88.9%) and resistant to minocycline(81.5%) and gentamicin(70.4%). 9) The Pseudomonas was sensitive to amikadn(86.4%), gemtamicin(59.1%) and resistant to minocycline(90.9%), ampicillin(86.4%) and cephalothin(86.4%).

Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.
