Surgical Skill Labs for Robotic Mastectomy and Educational Program Using a Surgical Guide by Artificial Intelligence

The goal of this prospective study is to investigate the satisfaction, NASA-Task Load Index (TLX), and surgical proficiency of a robotic breast surgery education program using cadaver or porcine models, as well as to develop an AI-based surgical guide for utilization within the educational program in trainees for robotic breast surgery. The main question\[s\]it aims to evaluate : * Satisfaction questionnaire of a educational program * NASA-TLX of a educational program * global evaluative assessment of robotic skills (GEARS) of a robotic breast surgery for surgical proficiency Participants will participate the educational program and fill out a satisfaction questionnaire and NASA-TLX. The tutor evaluates GEARS for 15 minutes at the beginning and end of training. After the development of the surgical guide based on AI, researchers will compare a training group with or without surgical guide to see the effect of the surgical guide.
