A Case Study on the Settlement Experience of North Korean Refugee Women in South Korea

Abstract

Unsupervised Video Object Segmentation (UVOS) refers to the challenging task of segmenting the prominent object in videos without manual guidance. In other words, the network detects the accurate region of the target object in a sequence of RGB frames without prior knowledge. In recent works, two approaches for UVOS have been discussed that can be divided into: appearance and appearance-motion based methods. Appearance based methods utilize the correlation information of inter-frames to capture target object that commonly appears in a sequence. However, these methods does not consider the motion of target object due to exploit the correlation information between randomly paired frames. Appearance-motion based methods, on the other hand, fuse the appearance features from RGB frames with the motion features from optical flow. Motion cue provides useful information since salient objects typically show distinctive motion in a sequence. However, these approaches have the limitation that the dependency on optical flow is dominant. In this paper, we propose a novel framework for UVOS that can address aforementioned limitations of two approaches in terms of both time and scale. Temporal Alignment Fusion aligns the saliency information of adjacent frames with the target frame to leverage the information of adjacent frames. Scale Alignment Decoder predicts the target object mask precisely by aggregating differently scaled feature maps via continuous mapping with implicit neural representation. We present experimental results on public benchmark datasets, DAVIS 2016 and FBMS, which demonstrate the effectiveness of our method. Furthermore, we outperform the state-of-the-art methods on DAVIS 2016.

Polyvictimization Risk Among North Korean Refugee Women in South Korea

“…NK refugee women are often exposed to traumatic events, and a small but significant number of NK refugee women experience sexual assaults en route to South Korea (Lee & Lee, 2020; Korean Ministry of Gender Equality and Family, 2012). NK refugee women are vulnerable to different types of victimization, and this state continues even after they settle in South Korea.…”

The effect of group art therapy on acculturative and academic stress of Chinese graduate students in South Korea

“…Originally designed by Sandhu and Asrabadi (1994) and modified by Lee (1995) to evaluate the cultural adaptation stress of international students in South Korea, this study used the modified version of the Acculturative Stress for International Students (ASIS) scale to assess acculturative stress. The modified self-assessed 24-item scale (“cultural adaptation stress scale”) measures the following seven sub-factors of acculturative stress: “perceived discrimination” (9 items), “homesickness” (3 items), “perceived hate/rejection” (5 items), “fear” (4 items), “stress due to change/culture shock” (3 items).…”
