OBJECTIVE To determine optimal scissor blade design and surgical approach to facilitate obtaining a long optic nerve segment during enucleation procedures. METHODS Two hundred mock enucleations were performed with the use of a human child skull model and a silicone sphere to simulate an eye. Temporal and nasal approaches with scissor blades with noncurved, mildly curved, or strongly curved bl...

This paper presents an efficient graph-based image segmentation algorithm based on finding the shortest closed directed walks surrounding a given point in the image. Our work is motivated by the Intelligent Scissors algorithm, which finds open contours using the shortestpath algorithm, and the Corridor Scissors algorithm, which is able to find closed contours. Both of these algorithms focus on ...

The purpose of this study was to develop a cognitive enhancement gymnastics program for the elderly with dementia and to verify its effect. The study was conducted on 27 people with dementia being treated in a dementia day care center in Incheon city. No statistically significant differences were found in the measures Mini-Mental State Examination for Dementia Screening (MMSE-DS), Short Geriatr...

Background Axillary osmidrosis is a disease characterized by axillary malodor. The conventional treatment method of subdermal excision uses Metzenbaum scissors. Recently, using the Versajet system was introduced. However, it an expensive surgical tool, and recent study demonstrated higher frequency skin necrosis with Versajet. We propose novel, cost-effective, safe that utilizes electrosurgical...

In this paper, we propose a hand shape recognition method using the sEMG (surface electromyography) of the upper extremity. The upper extremity sEMG is acquired using Myo which is a wearable device. The target hand shapes are three: Rock, Paper, and Scissors. For hand shape recognition, four features obtained with FFT and wavelet transform are used. SVM and an improved k-NN are used for classif...

Buttons & Scissors is a popular single-player puzzle. A level is played on an n-by-n grid, where each position is empty or has a single coloured button sewn onto it. The player’s goal is to remove all of the buttons using a sequence of horizontal, vertical, and diagonal scissor cuts. Each cut removes all buttons between two distinct buttons of the same colour, and is not valid if there is an in...

Heterogeneous catalysts play an important role in surface catalytic reactions, but selective bond breaking and control of reaction products in catalytic processes remain significant challenges. High-vacuum tip-enhanced Raman spectroscopy (HV-TERS) is one of the best candidates to realize surface catalytic reactions. Herein, HV-TERS was employed in a new method to control dissociation by using h...
