        Diminished reality using semantic segmentation and generative adversarial network for landscape assessment: evaluation of image inpainting according to colour vision

        Kikuchi Takuya,Fukuda Tomohiro,Yabuki Nobuyoshi 한국CDE학회 2022 Journal of computational design and engineering Vol.9 No.5

        The objective of this research is to develop a method to detect and virtually remove representations of existing buildings from a video stream in real-time for the purpose of visualizing a future scenario without these buildings. This is done by using semantic segmentation, which eliminates the need to create three-dimensional models of the buildings and the surrounding scenery, and a generative adversarial network (GAN), a deep learning method for generating images. Real-time communication between devices enables users to utilize only portable devices equipped with a camera to visualize the future landscape onsite. As verification of the proposed method’s usefulness, we evaluated the complementation accuracy of the GAN and real-time performance of the entire method. The results indicated that the process is completed accurately when the area to be complemented is less than 15% of the view and that the process runs at 5.71 fps. The proposed method enables users to understand intuitively the future landscape and contributes to reducing the time and cost for building consensus.

        Effects of mosapride on motility of the small intestine and caecum in normal horses after jejunocaecostomy

        Kouichi Okamura,Takuya Kikuchi,Aya Murata,이인형,Haruo Yamada,Hisashi Inokuma,Naoki Sasaki 대한수의학회 2009 JOURNAL OF VETERINARY SCIENCE Vol.10 No.2

        The purpose of the present study was to evaluate the prokinetic effects of mosapride with non-invasive assessment of myoelectrical activity in the small intestine and caecum of healthy horses after jejunocaecostomy. Six horses underwent celiotomy and jejunocaecostomy, and were treated with mosapride (treated group) at 1.5 mg/kg per osos once daily for 5 days after surgery. The other six horses did not receive treatment and were used as controls (non-treated group). The electrointestinography (EIG) maximum amplitude was used to measure intestinal motility. Motility significantly decreased following surgery. In the treated group, the EIG maximum amplitude of the small intestine was significantly higher than in the controls from day 6∼31 after treatment. These findings clearly indicate that mosapride could overcome the decline of intestinal motility after jejunocaecostomy in normal horses.

        Surgical Outcomes of Cervical Myelopathy in Patients with Athetoid Cerebral Palsy: A 5-Year Follow-Up

        Kazuyuki Watanabe,Koji Otani,Takuya Nikaido,Kinshi Kato,Hiroshi Kobayashi,Shoji Yabuki,Shin-ichi Kikuchi,Shinichi Konno 대한척추외과학회 2017 Asian Spine Journal Vol.11 No.6

        Study Design: Observational cohort study. Purpose: To assess the surgical outcomes of posterior decompression and fusion for cervical myelopathy in patients with athetoid cerebral palsy. Overview of Literature: Patients with athetoid cerebral palsy demonstrate involuntary movements and develop severe cervical spondylosis with kyphosis. In these patients, surgery is often performed at an early age because of myelopathy. A few studies have reported about the long-term outcomes of surgical treatment; however, they contain insufficient information. Methods: From 2003 to 2008, 13 patients with cervical myelopathy due to athetoid cerebral palsy underwent posterior fusion surgery and were included in this study. The Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), C2–7 angle on radiography, and need for additional surgical treatment were examined at 1 and 5 years postoperatively. Results: The mean C2–7 angle was −10.5°±21.1° preoperatively and was corrected to −2.9°±13.5° immediately postoperatively. This improvement was maintained for 5 years. The JOA score was 9.5±2.5 preoperatively and 12.2±1.7 at the 5-year follow-up. NDI was 17±6.9 preoperatively and 16±7.5 at the 5-year follow-up. Patient satisfaction with surgery on a 100-point scale was 62.2±22.5 at the 5-year follow-up. Three patients needed additional surgery for loosening of screws. These results demonstrate good surgical outcomes for posterior fusion at 5 years. Conclusions: Posterior decompression and fusion should be considered a viable option for cervical myelopathy in patients with athetoid cerebral palsy.
