The education based on synesthesia has been used to be applied for several years. Especially, We focused on the Coloured-hearing Synesthesia for music education for children who have difficulty in practicing pitch by using the serious game based on Coloured-hearing theory. Also, smart platform is flexible for several sort of video games so we expect good accessibility for children. For proving the effectiveness for education by using this technology and theory, we design the serious game for music called “Bunny’s Cave” based on Coloured-hearing theory and conduct the usability test aimed at 3rd grade student in elementary school.

Neurotized melanocytic nevus (NMN) is categorized into intradermal/intramucosal type of acquired melanocytic nevus. In contrast to typical intramucosal nevus which has relatively distinct histological features, the diagnosis of NMN requires more attention due to its mimicry of benign neural tumors such as neurofibroma. The majority of lesional cells, NMN cells, showed a spindle cell morphology and abundant, eosinophilic cytoplasm which were positive for S-100, vimentin, and collagen type IV. Positive reaction for MART-1 was detected in the NMN cells as well as in the epithelioid nevus cells beneath the epithelium. Neurofibroma exhibited diffuse positivity for S-100, vimentin, CD34 and collagen type IV, but never expressed MART-1. Toluidine blue stained the numerous mast cells scattered in the lesion of neurofibroma, compared to the relatively minor detection of mast cells in NMN. Therefore, MART-1 is a useful marker in differentiating NMN from neurofibroma.

생쥐에 1 Gray(Gy)와 3 Gy의 방사선을 조사한 후 시간에 따라 골격근, 심장, 신장, 간 및 정소조직의 형태적 변화를 확인하였다. H-B(hematoxylin-eosin)염색 결과 apoptotic body는 다른 조직에 비해 간조직에서 쉽게 관찰되었고, 조사량에 비례하였으며 대부분의 조직에서 조사 후 1일에, 정소조직에서는 7일에 많이 관찰되었다. TUNEL (terminal deoxyribonucleotidyl transferase-medi
