This paper discusses the main benefits of ZNS and shows why can be deprived internal parallelism when downsizing its zone writable capacity. To this end, we use two production SSDs quantitively analyze performance degradation caused by inter-zone interference. We then suggest a simple mechanism to detect zone-to-zone relationships generating interference schedule I/O requests being aware parallelism. Our evaluation results using real devices show that our improve bandwidth latency Linux's...

Flexible strain sensors are receiving a great deal of interest owing to their prospective applications in monitoring various human activities. Among efforts enhance the sensitivity sensors, pre-crack generation has been well explored for elastic polymers but rarely on textile substrates. Herein, highly sensitive textile-based sensor was fabricated via dip-coat-stretch approach: polyester woven band dipped into ink containing single-walled carbon nanotubes coated with silver paste and...
This study evaluates the mapping accuracy between textile stretch sensor data and surface electromyography (sEMG) signals using Multilayer Perceptron (MLP), Convolutional Neural Network (CNN), Residual (ResNet) models. Data from forearm, biceps brachii, triceps brachii were analyzed Root Mean Square Error (RMSE) R2 as performance metrics. ResNet achieved lowest RMSE (e.g., 0.1285 for brachii) highest (0.8372), outperforming CNN (RMSE: 0.1455; R2: 0.7639) MLP 0.1789; 0.6722). The residual...
Measuring breathing changes during exercise is crucial for healthcare applications. This study used wearable capacitive sensors to capture abdominal motion and extract patterns. Data preprocessing methods included filtering normalization, followed by feature extraction classification. Despite the growing interest in respiratory monitoring, research on a deep learning-based analysis of data remains limited. To address this gap, we optimized CNN ResNet through systematic hyperparameter tuning,...

We introduce EfficientCL, a memory-efficient continual pretraining method that applies contrastive learning with novel data augmentation and curriculum learning. For augmentation, we stack two types of operation sequentially: cutoff PCA jittering. While steps proceed, apply by incrementing the degree for each difficulty step. After is finished, applied on projected embeddings original augmented examples. When finetuned GLUE benchmark, our model outperforms baseline models, especially...
Abstract Warning: This paper contains examples of stereotypes and biases.

건강의 사회적 결정요인 패러다임은 건강에 영향을 주는 요인으로 사회적, 환경적, 정치적, 경제적 조건들을 강조한다. 즉, 건강과 안녕은 신체적 상태 뿐 아니라 상황을 반영하는 것임을 주장한다. 본 연구는 결정요인의 틀을 적용하여 분석기간 중 우울하지 않았던 사람이 처음으로 우울을 경험하는 데 미치는 요인을 종단적으로 검증하였다. 이를 위해 한국복지패널의 3차부터 14차까지 12년간 자료를 활용하였으며 이산시간위험모형분석을 수행하였다. 주요 변수로는 우울, 학력, 저소득층가구여부, 건강상태, 고용형태, 자본(신뢰, 호혜성), 박탈경험, 주거빈곤여부를 포함하였다. 연구결과 소득이 낮을수록, 교육수준이 그리고 고용형태가 불안정할수록 이들이 경험할 위험이 높아지는 것으로 나타났다. 주거상황과 사회경제적 박탈 역시 예측하는 요인이었으며, 자본으로 투입한 변수 신뢰수준은 그 정도가 호혜수준은 높을수록 우울경험 가능성이 높아졌다. 우울에 대한 개입과 예방을 위해서는 개인차원의 접근 요인의...
