Recent hand tracking systems and wearable haptic devices have contributed to enhancing user experience in virtual environments. However, controllers are still prevalent in virtual reality (VR) games as a main interaction device. Also, haptic devices are rare and not widely accepted by users. In this article, we examined the effects of interaction methods and vibrotactile feedback on users’ sense of presence, engagement, usability, and task performance in a VR game. In our experiment, 36 particip

<b><i>Objective:</i></b> To compare perioperative outcomes of robotic single-site (RSS) surgery with conventional single-port laparoendoscopic surgery for the treatment of advanced-stage endometriosis. <b><i>Materials and Methods:</i></b> This is a retrospective cohort study that included 120 patients who received single-port laparoendoscopic surgery or RSS surgery for the treatment of advanced-stage endometriosis at Ewha Womans University's Mokdong Hospital in Seoul, Korea between December 2014

The new vaginal cuff suturing techniques may convince more surgeons to perform robotic single-site hysterectomies more frequently and with greater ease.

BackgroundApproximately 36% of all cancer patients in Korea receive radiotherapy, a key modality of cancer treatment alongside surgery and chemotherapy.Diverse therapeutic techniques have resulted from advances in radiological technology and treatment devices, contributing to the improvement of the quality of treatment and patients' quality of life.According to 2022 data from the Korea Institute of Radiological Medical Sciences, 7.8% of female patients who underwent radiotherapy in 2019 received

Abstract New technologies have recently advanced user experiences in virtual reality (VR), whereas full sensation of diverse modalities has been not achieved yet. If any, haptic feedback has been delivered via bulky gloves. We have developed a novel thimble device that can deliver vibrotactile feedback via one fingertip. With this device, in the present study we investigated the effects of interaction methods and vibrotactile feedback on users' social presence, presence, engagement, workload, an

Objective : The aim of this study was to determine annexin II expression in cervical cancer. Methods : In Ewha Womans University Mokdong Hospital, normal and cervical cancer tissues were obtained from healthy women (n=11), from patients with cervical intraepithelial neoplasia (CIN, n=11) and from patients with cervical cancer (n=33). The expressions of annexin II mRNA and protein were examined by quantitative competitive-PCR and by western blot analysis. Annexin II mRNA and protein expressions w

Objective: Threre are several proteolytic enzymes such as Matrix Metalloproteinases (MMP), which are involved in tumor invasion and metastasis. The aim of this study was to determine the exprssion of Membranous Type MMPs (MT-MMPs) and investigate the relationship between their expression and questioned whether their expression is related to stages and other prognostic factors of cervical cancer. Methods: The cervical and cervical cancer tissues were taken from the patients; healthy women (n=14),
