  • A numerical human head/neck model was constructed for analyzing the implication in decleration injuries. This model consists of nine rigid bodies representing the head, cervical vertebrae C1-C7, and T1. These rigid bodies were connected by intervertebral disks described by massless beam elements. Muscles and ligaments were also incoperated in the model represented by nonlinear spring and viscoblastic element respectively Agreement of the analytical kinematic response with the results of experimental data from a volunteer run was satisfactory. Moreover, possible injury estimation from the calculated moment, force variations in the disc, and force variation in ligaments matched well with clinical observations.

  • This report presents a case of cervical pneumatocysts as an incidental finding on cone-beam computed tomography. Pneumatocysts are gas-containing lesions of unknown etiology. They usually present in the ilium or sacrum, adjacent to the sacroiliac joint. In the literature, 21 case reports have described cervical pneumatocysts. Cervical pneumatocysts should be differentiated from other lesions, such as osteomyelitis, osteonecrosis, and neoplasms, as well as post-traumatic and post-surgical cases. Computed tomography, cone-beam computed tomography, and magnetic resonance imaging are appropriate tools to diagnose cervical pneumatocysts.

  • Discospondylitis is an infection of an intervertebral disk with concurrent osteomyelitis of contiguous vertebrae. Clinical signs are variable and include pain, fever, anorexia, weight loss, depression, stilted gait and paresis or paralysis. A seven-year-old, intact female Yurkshire terrier dog was refered to the Vfterinary Medicine Teaching Hospital of Seoul National University because of intermitent pain of unknown cause for 2 weeks. On physical examination, pain was evident when spines were manipulated, especially thoracolumbar junction part. No neurologic deficits were deteced in the general neurologic test. Spinal radiography demonstrated the bony lysis of the vertebral end plates and sclerosis of the $T_{12-13}$ vertebral body. Based on the results of examinations, the dog was diagnosed as discospondylitis and recoverd following antibiotic therapy.

  • Pectus excavatum (PE) is a ventral chest wall deformity, also known as funnel chest, sunken chest, chondrosternal depression or koilosternia. The 4 months old, 1.3 kg intact-female Pekingese dog was evaluated for acute semicoma and convulsion. The client reported that this patient have had chronic loss of appetite, intermittent dyspnea and palpable sunken breast. The other littermates did not show any abnormalities. On physical examination, cachexia (BCS 1/5), concave sternum, flatten thoracic cavity and cardiac murmur were observed. On radiographic study, the caudal sternum cave to vertebrae and narrowing thoracic cavity. The severities of thoracic deformity were evaluated by deformation indices such as-Frontosagittal index (FSI) and vertebral index (VI). Moderate to severe PE was founded by the radiological measurements.

  • A 7-year-old, female pointer dog was referred to the SNU Veterinary Medicine Teaching Hospital for the evaluation of lameness in the pelvic limb of 10 days' duration. After the treatment for 2 weeks (carprofen 2.2 mg/kg, bid), the progressive, symmetric, ambulatory caudal paraparesis was profound. In the spinal myelography, left lateral extradural compression of the spinal cord over the ninth and tenth thoracic vertebral bodies was found. A left hemilaminectomy of the ninth and tenth thoracic vertebrae was done. A 1.5-cm-long, white extradural mass occupied the left side of the spinal canal. The tumor was identified histologically as lipoma. The 6 weeks after surgery the dog's complaints were much improved. Continuous evaluation is needed.

  • 한국산 새코미꾸리속 Koreocobitis에는 새코미꾸리 Koreocobitis rotundicaudata와 얼룩새코미꾸리 (신종) K. naktongensis 2종이 분포한다. 신종인 얼룩새코미꾸리는 새코미꾸리에 비해 갈색의 얼룩무늬반점, 절단형의 꼬리지느러미 후연, 척수골 수의 감소, 긴 두부 등에서 형태적인 뚜렷한 차이를 보여 주고 있으며, 낙동강에만 제한 분포하고 있어 생물지리적으로 주목된다. 또한 이들 2종에 대한 검색표와 함께 형태적 특징을 기재하였다.

  • The purpose of this study was to examine the effect of kinematic taping on respiratory muscle strength in smokers. Twenty - five university students who smoke were involved in the study. All participants were applied to kinematic taping to breathe deeply again. Subjects sit on their backs straight up and place their hands on their thighs. Tape 1 is applied from the lower prominent neck vertebrae(seven cervical vertebra) inward and downward, past shoulder blade, around ribs to the lower tip of sternum. Tape 2 extends to the lower, outer edge of shoulder blade, around ribs to the lower tip of sternum. Respiratory muscle strength was measured with Micro Mouth Pressure Measurement before and after taping. The application of kinematic taping significantly improved the inspiratory and expiratory muscle strength (p<.05). These findings suggest that kinematic taping effective in improving respiratory muscle strength and deep breathing.
