Instability in financial markets represents a considerable risk to investors; examples of instability include a market crash caused by systematic risks and abnormal stock price volatility caused by artificial hype. The early detection of abnormal beh

Native-English-speaking teachers (NESTs) have not been examined to the same extent as the non-native-English-speaking teachers (NNESTs) in research. A summary of research results focusing on NNESTs was found (e.g., Moussu & Llurda in Languae Teaching

The seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was examined among 105 healthcare workers (HCWs) exposed to four patients who were laboratory confirmed with coronavirus disease 2019 (COVID-19), the disease caused by

Market structure provides concrete information about the market. Price patterns can be imagined as the evidence of a supply and demand states in the market. Price shifts higher as the demands exceed the available supply and vice-versa. These patterns

The diamond encoding technique controls payload and image quality by a k value. Although a small increase in k can increase payload, it also increases image distortion. In this paper, we proposed an improvement scheme to the diamond encoding techniqu

Jung et al., IEEE Signal Processing Letters, 18, 2, 95, 2011 proposed a reversible data hiding method considering the human visual system (HVS). They employed the mean of visited neighboring pixels to predict the current pixel value, and estimated th

This paper proposes improvements to the reversible hiding technique proposed in by Hong et al. in 2012. The proposed technique is based on the characteristics of the human visual on neighboring pixel values to obtain the average for calculating the m

We propose a reversible data hiding technique to improve Hong and Chen’s (2010) method. Hong and Chen divide the cover image into pixel group, and use reference pixels to predict other pixel values. Data are then embedded by modifying the predictio

This paper proposes a lossless data embedding method for Block Truncation Coding (BTC) compressed images based on prediction and histogram shifting techniques. Because BTC is easy to implement, and requires significantly less CPU cost, it has arouse
