English Abstract: This paper studies the impact of immigration on native labor market outcomes in Korea. We exploit the variation in immigration flows in an education-experience cell and find that, on average, immigration has no harmful effect on the wages or employment of native workers....

English Abstract: We examine the economic impact of the diplomatic conflict using the THAAD crisis between South Korea and China as a case study. Using the synthetic control method, we estimate the conflict’s impacts on Chinese tourists to Korea and stock prices of China-related Korean firms....

Unbalanced data classification has been a long-standing issue in the field of medical vision science. We introduced the methods of support vector machines (SVM) with active learning (AL) to improve prediction of unbalanced classes in the medical imaging field. A standard SVM algorithm with four...

MnO2+δ (Manganese oxide) nanoflakes were synthesized for use as electrode material in electrochemical supercapacitors. The nanoflakes were produced via RF-magnetron sputtering with various excess oxygen contents (δ), and the electrochemical supercapacitive properties of the MnO2+δ nanoflakes...

Closed-End Fund (CEF) discounts have intrigued researchers for decades. Of the many explanations offered, the behavioural framework of Lee <italic>et al</italic>. (1991), which posits noise traders subject to sentiment, is the most discussed. In this article, we contribute some novel evidence to the evaluation...

Novel composites consisting of cobalt–boron (CoB) catalyst and sodium borohydride (NaBH4) implantation in polymers (polyethylene glycol (PEG) or sodium alginate) were prepared for portable hydrogen production. The CoB catalyst was synthesized by the reduction of cobalt salt in NaBH4 solution...
