A study on phytoplankton community was carried out from June, 1992 to May, 1993 at selected stations in Hoedong Reservoir. The phytoplankton are identified as 176 taxa including 5 phylum, 67 genera. The important species in this reservoir were Asterionella formosa, C meneghiniana, Dictyosphaerium plilchellum, Fragilaria crotonensis, Melosira distans, M grantulata, M. granulata var. angustissima, M. granulate var. angntissima f. spirdis, Micractinium pussillum, Microcystis aeruginosa, Pundorina morn, Pediastrum boryanum, P. duplex, Peridinium sp., Scenedesmus quadriauda, Synedra acus, S. rumpens and S. ulna. The causative species of water bloom were identified as Microcystis aeruginsa, Trahellomonas hispida, Ceratium hirwdinella, Peridinium sp., Melosira italica, Staurastrum dorsidentiferum var. onatum in the area. During the study periods standing crcps of phytoplankton were maximum in August, 1992 and minimum in December 1992. The species dominance index and diversity index were ranged 24.7-99.9, 0.001-3.06, respectively. Key Words : phytoplankton community, causative species of water bloom, standing crops. dominance index, species diversity index.

The purpose of this study is for old-aged women to analysis variation of Body composition and BMD so that help to keep healthy life by doing low-intensity workout. the subjects for this study consist of 20 persons being aged over 65 women, doing not regular workout, living in P metropolitan, and do workout for 12 weeks by catergorizing into 2 groups in half depending upon whether doing workout or not. Two-way Repeated Measures ANOVA of SPSS 18.0 was used for data processing. the statistical significant is set as p<.05. In result, there's none of dramatical difference in radius, ulna's BMD. there is dramatical difference in (%)Fat, WHR in workout group but none difference in LBM.

A male, 11-month-old, Shih-tzu dog weighing 5.2kg showing knuckling secondary to severe cranial bowing of left antebrachium with valgus deformity of the carpus was presented to the Veterinary Medicine Teaching Hospital of Seoul National University. Radiographic findings were a premature closure of the distal ulnar physis, a cranial bowing of the radius, subluxation of the elbow joint, and degenerative changes in the carpal joint. The patient was treated by performing an oblique osteotomy of the radius and ulna, followed by application of External Skeletal Fixations. At 18 weeks postoperatively, the radius was healed. An incongruency of the elbow joint and radial angular deformity was corrected.

Giant cell tumor of bone is relatively common neoplasm usually involving epiphysis of long bone. And rarely it involves the diaphysis or metaphysis without epiphyseal extension. We report on an 18-year-old girl with giant cell tumor of ulnar diaphysis. She was treated with wide excision and reconstuction with nonvascularized autogenous fibular graft. We harvested fibular fragment preserving fibular continuity to reduce donor site morbidity. Surgical outcome and functional result was excellent.

Three dimensional computed tomographic images were obtained in two cases with trauma. The first case of a 3 year-old male Maltese, with ataxia and head tilting due to head trauma was referred to veterinary medical teaching hospital, Seoul National University. Remarkable findings were not found on survey radiographs. With the help of three-dimensional reconstruction computed tomographic imaging, parietal and occipital bone fracture was identified. The second case of 4 month-old female Yorkshire terrier with left forelimb lameness was referred right after trauma. Survey radiography showed obvious incongruity of the elbow joint. Lateral and medial condyle of the left humerus fracture and lateral displacement of the left ulna were apparent in three-dimensional computed tomographic image. It was considered that three-dimensional computed tomography could be used as an aid modality for the exact evaluation of extends and degree of fracture as well as planning of orthopedic surgery.

We report a case of 44 years old male patient with neuroma-in-continuity of ulna nerve. In the patient's past history, he had received operative treatment for the open supracondylar fracture of right distal humerus and ulnar nerve injury at 10 years ago, and neurolysis was tried 2 times due to severe neuropathic pain. Despite of these operations, the symptom was not improved. In operative field, we noticed neuroma-in-continuity and decided to resect the neuroma until normal nerve fascicle was noted. The nerve cable graft was done with auto sural nerve on the defect site and the nerve was wrapped with small saphenous vein. At post operative 7 months, pain was markedly decreased and sensory recovery was slightly improved and patient was satisfied with the result.

A wild Falco tinnunculus, which is a small raptor, was rescued and presented due to immobilization. On physical examination, a left ulnar fracture was detected, which was reduced with an intramedullary (IM) pin and soft bandaging. Passive range of motion (PROM) exercises were then conducted to prevent complications such as ankylosis. The raptor was released into the wild four weeks postoperatively. We suggest that IM pinning with bandaging and appropriate PROM exercises may effectively treat ulnar fractures in small raptors.

Anterior interosseous nerve palsy is known to occur uncommonly because of its compression by the accessory head of flexor pollicis longus(AHFPL) in the forearm. During routine educational dissection, we found 7 AHFPLs in 12 upper limbs of 6 adults Korean Jeju islander cadavers, which inserted onto flexor pollicis longus. Three AHFPLs of them arose from coronoid process of the ulna, and the others arose independently from the flexor digitorum superficialis (FDS). Using the topographical relationship of the anterior interosseous nerve to the AHFPL, all anterior interosseous nerve was crossed the tendinous part of the AHFPL. This study has shown that there are discrepancies in the origin of AHFPL and the location of the anterior interosseous nerve in Koreans, which is supposed to be related to unique genetic pool in Jeju Island.

남조류 제어능이 밝혀진 국내산 말조개와 논우렁이를 금강수계에서 채집하여, 저온기 부영양 호수에서 우점하는 규조류에 대한 섭식특성을 파악하고자, 두 패류를 단독 또는 혼합적용하고, 수조내 엽록소-a, 조류현존량, 섭식율 및 배설물 생산량의 변화를 각각 조사하였다. 섭식 실험은 패류밀도에 따라 말조개 단독처리군 5가지, 논우렁이 단독처리군 5가지, 두 패류의 혼합 처리군 4가지 등으로 구분하여 각각 3회씩 반복 실험하였다. 분석결과, 모든 패류 처리군에서 엽록소-a (또는 조류현존량 농도)가 뚜렷하게 감소하였으며, 말조개와 말조개 밀도가 높은 혼합군에서 조류제어율이 높았다. 각 출현종에 대한 패류의 조류제어능은 Synedra ulna, Scenedesmus sp., Ankistrodesmus falcatus 등은 말조개 밀도가 높을수록, Diatoma vulgare는 혼합 처리군에서 각각 높게 제어된 반면, Cryptomonas ovata는 고밀도 논우렁이 처리군에서 오히려 20% 성장을 유도하였다. 패류의 섭식율은 패류와 처리시간에 따라 차이를 보였는데, 초기에는 운동성이 좋은 논우렁이가 강한 섭식을 보인 반면, 시간이 경과함에 따라 말조개 및 고밀도 말조개 혼합 처리군에서 섭식율이 높았다. 패류의 배설물 생산은 혼합 처리군에서 가장 높았으며, 60 ${\mu}m$ 이상의 크기에서 높게 나타났다. 본 연구에서 국내산 말조개와 논우렁이를 단독 또는 혼합 적용시 모든 처리군에서 규조류가 뚜렷하게 감소하였으며, 말조개나 말조개 혼합 비율이 높을수록 제어율이 높았다. 따라서 앞으로 패류들의 현장적용 기술이 개발된다면 저온기 규조류 대발생의 생태친화적 제어가 가능할 것으로 사료되었다.
