The exact preoperative diagnosis in the cerebellar midline tumor is crucial to design the operative plan such as the extent of tumor resection, preservation of critical structures, and need to be shunt. We experienced a cystic tumor on the middle cerebellum, which were suspected as usual radiologic diagnoses but were revealed as rare entities in the pathology. A 40 year-old woman suffered from lasting headache and ataxia. In the radiologic finding, it was a huge cystic mass with a mural nodule. We took into consideration cerebellar tumor such as dermoid cyst, hemangioblatoma, or cystic astrocytoma. The pathologic diagnosis was the mature teratoma. We report a case of mature teratoma occured in the midline cerebellum and review it with pertinent literatures.

Spontaneous intracranial hemorrage is rare in the childhood, which is usually caused by vascular anomalies, blood dyscrasia and trauma. A 15-year-old child presented with sudden headache while he was studying. The fretures of radiologic images suggested the cerebellar hematoma caused by the underlying lesion such as vascular malformation or cavernous hemangioma. The operation finding revealed that the hematoma was caused by a tumor, which adhered to the superior medullary velum of cerebellum. The pathology revealed it to be hemorrhagic pilocytic astrocytoma. The hemorrhagic pilocytic astrocytoma should be considered in the diagnosis of the lesion in cerebellar hematoma.

The free face is an important part in the blasting design and plan. Most of study on the free face is referred to concern with fragmentation volume and determination of charge per delay. But the characteristic of vibration for the direction of the free face short of studies. This study shows the difference and characteristics of the vibration velocity for the measuring point and the direction of the free face. At the velocity of vibration, the back of the free face is over the front (Probably 1.20~1.29 times). A nomogram was made in relation to the maximum charge weight per delay on the basis of the 95% vibration blast equation and the velocity of vibration allowance set 5㎜/sec. Scaled distance was 29.71㎏/m^(1/2), 39.63㎏/m^(1/3) on the front of the free face and 34.03㎏/m^(1/2), 45.20m/㎏^(1/3) on the back of the free face.

The thoracic spine is rigidly stabilized by the ribs, anterior and posterior longitudinal ligaments, and a sagittal orientation of the facet joints that resists axial rotation and horizontal translation. Thus, a significant force is required to cause a fracture and dislocation in the thoracic spine. A 32-year-old man was involved in a motor-vehicle accident and presented with complete paraplegia and spondyloptosis on the 8th thoracic vertebral segment. He also suffered with hypoxia and hypovolemic shock. Posterior reduction and fixation with pedicle screw was achieved with the anatomic alignment and rigid stability. This posterior technique for thoracic spondyloptosis is believed to be sufficient to make good alignment and solid fixation.

SiH_4 기체에 PH_3 및 B_2H_6 기체를 0.7% 체적비로 혼합하여 rf glow 방전법으로 n형 및 p형 a-Si:H 박막을 기판온도 120℃에서 제작하여, 광투과도 측정, 열처리에 따른 전기 전도도의 변화 등을 조사하여 이들의 doping 효과를 연구하였다. n형, p형 및 undoped a-Si:H 박막의 optical gap은 각각 1.73eV, 1.86eV 및 1.86eV로 doping이 많이 이루어질수록 줄어 들었다. 250℃에서 열처리한 시료들의 상온에서의 전도도는 각각 2×10^-2Ω^-1㎝^-1, 5×10^-8Ω^-1㎝^-1, 5×10^-7Ω^-1㎝^-1이었고, 활성화 에너지 ??E는 각각 0.16eV, 0.49eV 및 0.48eV이었다. 300℃에서 열처리한 결과, ??E는 줄어 들고 전도도는 증가하였다. 350℃ 및 450℃에서 열처리한 결과 dehydrogenation 효과로 인하여 n형과 p형은 서로 상반되는 결과를 보였다. 즉, n형 시료의 전도도는 감소하고 ??E는 증가하였지만, P형 시료의 전도도는 증가하고 ??E는 감소하였다. 저온 영역에서 구한 n형 시료의 전도도로부터 hopping 활성화 에너지를 구한 결과 0.085eV이었다. Thin n-type and p-type a-Si:H films were prepared by rf glow discharge decomposition of silane mixed with 7×10^-3 parts per volume of phospine or diborane. All specimens were deposited on glass substrates held at 120℃. In order to determine the doping effects the opital absorption and dc conductivity of these specimens were measured after annealing at various temperatures. The optical gap was 1.73eV in the case of the n-type specimens, 1.80eV for the p-type, and 1.86eV undoped. This showed that the gap width decreased as the doping increased. The room temperatuer conductivities of these specimens annealed at 250℃ were 2×10^-2Ω^-1㎝^-1, 5×10^-8Ω^-1㎝^-1, and 5×10^-7Ω^-1㎝^-1, respectively, and the activation energies, ??E, of these specimens were 0.16eV, 0.49eV, and 0.48eV, respectively. For specimens annealed at 300℃, ??E decreased and the conductivity increased. When these specimens were annealed at 350℃ and 450℃, dehydrogenation caused opposite effects on the n-type and p-type specimens; the conductivities of n-type specimens decreased and ??E increased, but the conductivities of p-type specimens increased and ??E decreased.From an investigation of the temperature dependence of the conductivity of the n-type specimen in the low temperature region, we determined that the hopping activation energy was 0.085eV.
