Y. W. KIM, Y. J. KIM, Mechanical Properties of Unilateral & Bilateral Movements in Isokinetic Knee Extension and Flexion. Korean Journal of Sport Biomechanics, Vol. 18, No. 3, pp. 83-92, 2008. The purpose of this study was to examine the mechanical properties and patterns of bilateral and unilateral movement under varying velocities and movement patterns. The unilateral and bilateral isokinetic knee extension and flexion were taken for three speeds of 13 healthy male subjects. Although there was bilateral facilitation at the speed of $450^{\circ}$/s for the bilateral movement of knee extension, as a whole there was less resultant torque and power of bilateral movement than summed unilateral under knee flexion and extension of 3 velocity condition. There was significant correlations between bilateral deficits within individuals observed for an the same movement($120^{\circ}-240^{\circ}$ flexion, $120-240^{\circ}$ extension, $240^{\circ}-450^{\circ}$ extension), which means that same agonist was recruited. On the contrary, although there was a tendency of a similar pattern of the individuals bilateral deficit according to the varying velocities, there was not a significant correlations between bilateral deficits of flexion and extension within individual, which means that different agonist was recruited. With the analyses of this results the individuals neuromuscular characteristics and the effecting factors for bilateral movement can be speculated upon.

Objective : To identify the effect of bilateral arm training for activities of daily living(ADL) of the chronic phase after stroke. Methods : 20 patients with stroke, randomized to an experimental group(n=10) and a control group(n=10). Both groups received the usual occupational therapy. In addition, an experimental group received an bilateral arm training, 30-min sessions per a day for 6 weeks. The Functional Independence Measure(FIM) was used to evaluate ADL for both groups. Results : First, there is a significant difference before and after receiving the bilateral arm training(p <.05). Second, there are significant differences in all ADL areas of Self-care, Transfer, Social cognition after bilateral arm training(p<.05). Third, there are significant differences in all sub-areas of Self-care, only stairs of Locomotion, and only Problem solving of Social cognition by comparing sub-areas as bilateral arm activity(before and after) and occupational therapy intervention(before and after). Conclusion : Using bilateral arm training for the chronic phase after stroke improved their abilities of ADL. Therefore, there are an expectation to use bilateral activity training for the chronic after stroke clinically and a need of further study about bilateral arm training related to ADL in the future.

Ipsilateral tonsillectomy and panendoscopy-guided biopsy following imaging studies are considered a standard procedure in the search for a primary origin in patients with cervical metastatic carcinoma of unknown origin(MUO). However, many authors recommended bilateral tonsillectomy for the determination of the primary site of a MUO, because cervical metastasis may occur contralateral to tonsillar carcinoma. The authors attempted to address the clinical implications of using routine bilateral tonsillectomy to determine the primary site of MUOs based on a case report of cervical MUO that was finally diagnosed as a bilateral synchronous tonsillar carcinoma with cervical metastasis after a diagnostic work-up that included bilateral tonsillectomy.

Coronary artery involvement in Takayasu's arteritis is a relatively rare, and potentially lethal but surgically correctable disease. A 28-year-old female was admitted for the evaluation of headache associated with dizziness, palpitation and claudication of left arm. Her aortogram and coronary angiogram showed Takayasu's arteritis with bilateral coronary ostial stenosis. We performed bilateral coronary ostioplasty with saphenous vein patch graft. The patient was discharged in good condition. We report this case with literature review.

Arare case of bilateral abducens nerve paralyses after rupture of a left posterior communicating artery(PcomA) aneurysm with multiple unruptured aneurysms in a 46-year-old female is presented. Sudden left abducens nerve paralysis followed by progressive right abducens nerve paralysis were present without additional neuroophthalmological signs. Postoperatively, bilateral abducens nerve paralyses gradually recovered and disappeared in 2 weeks. The authors reviewed and discussed the possible mechanisms involved in this uncommon neuro-ophthalmological manifestation.

고분자전해질형 연료전지에서는 수소이온의 이온전도성 저하를 방지하기 위하여 외부에서 가습하여 주는 방식이 일반적이지만, 가습에 소요되는 부품을 일부라도 제거할 경우 연료전지의 효율은 높이고 제작단가도 경감할 수 있다. 이를 위하여 저가습 및 무가습 실험을 수행하였으며, 정확한 data의 수집과 시험장비의 자동제어를 위하여 National Instrument사의 compact field point (cFP)를 사용하였다. Humidifier와 heater의 온도를 조절하여 공급유체의 상대습도 및 온도를 각각 조절하였으며, 이에 필요한 이론적 온도는 Antoine equation 을 사용하여 산정하였다. Anode와 cathode 양측 $100\%$ 가습 경우를 기준으로 가습량을 조절하면서 실험을 수행하였으며 성능 차이를 그래프로 도시하여 양측의 변화에 대한 영향을 볼수 있도록 하였다. Stack의 온도가 $70^{\circ}C$이고 양측 무가습일 경우에 성능 측정이 어려워서 stack의 온도를 저온에서부터 변화시키면서 무가습 성능을 실시간으로 측정하여 보았다. 일반적으로 hydronium ion은 anode측에서 cathode측으로 계속 이동하여야 전기를 생성할 수 있으므로 cathode측 무가습이 anode측 무가습보다 성능이 더 잘 나오는 것으로 예측하였으나 이와 반대되는 경향의 실험 결과를 얻었다. 양측 무가습의 경우에는 공기 중의 상대습도와 back diffusion 등에 영향을 받을 수 있으므로 각종 변수들의 영향을 분리하여 관찰할 수 있는 실험을 수행 중에 있다.

Bilateral diaphragmatic paralysis is a rare disease. It is caused by trauma, cardiothoracic surgery, neuromuscular disorders, corvical spondylosis, and infection. A 60 year-old male patient developed bilateral diaphragmatic paralysis after an on-bloc resection of thymic carcinoma which invaded the right upper lobe, pericardium, superior vena cava and innominate vein. Severe respiratory difficulty developed and ventilator weaning was impossible. We performed bilateral diaphragmatic plication. After the operation, satisfactorily ventilator weaning and sleeping in supine position were possible; therefore, we report this case.

The purpose of this study was to investigate the effects of occupation-based bilateral upper extremity training and transcranial direct current stimulation on upper limb function in stroke patients. The study group was divided into 13 experimental groups with occupation-based bilateral upper extremity training and transcranial direct current stimulation, and 13 controls with only occupation-based bilateral upper extremity training. A total of 4 weeks, 50 minutes, 5 times a week conducted, the patients were tested with Canadian Occupational Performance Measure(COPM), Accelerometer, Fugle-Meyer Assessment(FMA), and Motor Activity Log(MAL). As a result of the study, the experimental group and the control group showed significant improvement in both occupation satisfaction and performance, usage of the affected side and the tendon side, recovery of upper limb function, and quality of movement, In particular, the experimental group showed a significant difference in the amount of the affected side than the control group. Therefore, it was found that the combination of occupation-based bilateral upper extremity training and transcranial direct current stimulation had a positive effect on the recovery of upper limb function in stroke patients.

An 11 year-old intact female Yorkshire Terrier weighing 3.5 kg was presented with the complain of having a perineal mass, fecal incontinence and tenesmus. Physical examination revealed reducible bilateral ventral perineal mass, enlarged mammary gland and vaginal discharge. Bilateral ventral perineal hernia (BVPH) and pyometra were diagnosed based on the clinical and radiographic findings. Ovariohysterectomy was performed after general anaesthesia to treat pyometra. The BVPH was repaired by herniorrhaphy with semitendinosus muscle transposition along with colopexy and cystopexy. The postoperative radiographs and CT revealed a good correction of the BVPH. The patient showed good activity after 10 days and no complications were observed during a one year follow up period. BVPH can be successfully surgically managed by herniorrhaphy with semitendinosus muscle transposition along with cystopexy and colopexy in the dog.
