Most tasks of the large vertical or ceiling structures have been carried out by human power. Those tasks require us much operation costs and times, safety devices, etc. So the need of automation for those tasks have been rising. That automation needs a wall-climbing mobile vehicle. Most former researches are things about attachment devices and moving mechanisms. A wall-climbing mobile vehicle must be designed by a method different from the case of the vehicle of the horizontal environment. That is because gravity acts as a negative role on the stability of a wall-climbing vehicle. In this thesis, the particular shape characteristics of a wall-climbing mobile vehicle are derived by the wall-environment modeling. In addition, some design constraints of the permanent magnetic wheel as an attachment device was studied. According to those requirements and constraints, one specific wall-climbing mobile vehicle was designed and some experiments were made on the attachment ability of that vehicle.

Purpose: To observe the relationship of bilaminar zone of temporomandibular joint retrodiscal tissues to the disc condition. Materials and Methods : The upper and lower stratum of bilaminar zone were identified on magnetic resonance open mouth images of 148 joints from 74 patients with disc displacements. Results: Both strata were identifiable in 105 joints which had disc displacement with reduction. Lower stratum was not identifiable in 35 joints which had disc displacement without reduction but 12 of 35 had hyalinized posterior attachment where the disc was. The 8 joints which had partial disc displacement without reduction showed identifiable lower stratum at the reducing site which was medial. Conclusion: Disruption or no identification of lower stratum which corresponds to the condylar portion of posterior attachment may be the sign of disc displacement without reduction.

부분 무치악 환자에서 구강 기능의 회복을 위한 보철 계획을 수립할 때, 잔존하는 치아에 따라 다양한 치료 방법을 선택할 수 있다. 특히 대합이 상실된 소수의 잔존치가 불안정한 교합을 야기하는 엇갈린 교합의 경우, 대합 되는 위치에 임플란트를 식립함으로써 교합지지를 회복할 수 있다. 이 증례에서는 발치 후 엇갈린 교합이 된 환자에서 의치의 하중을 견딜 수 있도록 상악 잔존치에 대응하는 하악 무치악 부위에 임플란트를 식립하고 자석유지장치(magnetic attachment)를 연결하는 국소의치를 제작하였다. 또한 상악 전치의 돌출과 하악 입술 지지도가 부족한 것을 개선하고 싶어한 환자의 요구사항에 따라 상악 전치부 보철적 수복 및 하악 의치를 통해 심미적 안모를 회복하였다. 5개월 정기검진 결과, 환자는 저작 기능 및 심미적인 면에서 만족하였고 의치의 안정성 또한 잘 유지되고 있기에 이를 보고하고자 한다.

A 59-year-old female presented with headache and dizziness for one year. Magnetic resonance imaging revealed a $52{\times}28$ mm, wellcircumscribed, homogenously enhancing mass lesion without dural attachment located in the left lateral cerebellomedullary cistern. The tumor was excised, and a histological diagnosis was a mixed pattern meningioma of meningothelial and fibroblastic type. A meningioma in the posterior fossa without dural attachment is quite rare. We report a rare case of lateral cerebellomedullary cistern meningioma without dural attachment with literature review.
