Vestibular neuritis represents as a spinning type of dizines acompanied by nausea, vomiting. Central vertigo such as cerebellar uplies the cerebellum by branching out into superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery. The patient had spinning type of vertigo, nausea, vomiting on the day of visit without any otologic symptoms. Only spontaneous nystagmus was observed. After admission, the patients diziness aggravated and emergency brain magnetic resonance imaging was performed. As ess decreased, the folow-up imaging study showed improvement of the infarction, and the patient was discharged. We experienced three cases of PICA infarction presenting as peripheral types of dizzines, and therefore we are reporting the case. (Korean J Otorhinolaryngol-Head Neck Surg 2007 ;50 :941-6)

Background and Objectives:In normal postnatal mamalian inner ear sensory epithelium, regeneration of hair cells is a very rare event, but there is hair cell regeneration with partial restoration of the vestibular sensory epithelium following ototoxiIn this study, the efects of low-level laser on hair cell regeneration folowing gentamicin exposure in postnatal organotypic culture of rat utricles were investigated. Materials and Method:A long term organotypic culture of 2 to 7 day old rat utricular maculae was established to study aminoglycoside-induced vestibular hair cell renewal. The utricles were exposed to 1 mM of gentamicin for 48 hr and allowed to recover in a culture medium only or in a medium with daily iradiation of low-level laser, whereas the marker, to identify live hair cells in cultured tissues. Results:Los of hair cells was nearly stopped from 2 days after exposure to gentamicin;a peak of regeneration was reached after 18 days and sustained for two weks in the medium with the irradiation of low-level laser. Conclusion:These results suggest that low-level laser promotes spontaneous hair cell regeneration following gen-tamicin damage in utricular explants. (Korean J Otolaryngol 2007 ;50 :25-30)
증강현실(AR)을 활용한 디지로그 북 인터랙션디자인 연구(아동 서적물 중심으로)

Digilog book using augmented reality is a form that augmented reality is implemented by illuminating the camera embedded in the mobile image on the page registered as an image marker after downloading the application, which shows a fragmentary limitation in the content implementation method. Therefore, in this study, we proposed a pop-up multi-tracking method that enables two-way interaction in a digit log book using augmented reality technology. Through this, we commissioned an authorized agency to test the technical differentiation of augmented reality content for two prototypes of existing book-type Digilog Book and Pop-up-type Digilog Book. A test report was issued. The pop-up type digit log book suggested in this study enables the user to implement the interactive contents according to the user's action (movement). This can induce the interaction between the virtual image and the printed picture book and give the learner an interest and immersion, so that it is possible to express the interaction of the digital log book. 증강현실을 활용한 디지로그 북은 애플리케이션을 다운받은 후 모바일에 내장된 카메라를 Image Marker로 등록된 페이지에 비추면 증강현실이 구현되는 형태로서 콘텐츠 구현 방법에는 단편적 한계점을 나타내고 있다. 이에 본 연구에서는 증강현실 기술을 활용한 디지로그 북에 양방향 인터랙션이 가능한 팝업(Pop-up) 형태의 Multi-Tracking 방식을 제안하였다. 이를 통해 기존 책자형의 디지로그 북과 이번 연구에서 제안한 팝업(Pop-up)형태의 디지로그 북의 두 가지 프로토타입에 대한 증강현실 콘텐츠 구현에 따른 기술적 차별성에 대한 실험을 공인기관에 의뢰하여 검증하였고 시험성적서를 발급받았다. 연구에서 제안한 팝업(Pop-up)형태의 디지로그 북은 가상 이미지를 사용자의 행위(움직임)에 따른 인터랙션 콘텐츠 구현이 가능하여 책의 물리적인 변화자체가 가상콘텐츠에도 전달되는 양방향 인터랙티브 콘텐츠의 장점을 갖고 있으며, 이는 가상 이미지와 인쇄 그림책 간의 상호작용을 유도하고 학습자에게 흥미 유발 및 몰입감을 줄 수 있어 차별화된 디지로그 북의 인터랙션의 표현이 가능할 것으로 보여진다.
