Although the outward migration of North Korean refugees has received increasing attention in scholarly circles, little research has been done on migration to North Korea. Drawing on ethnographic and archival research, this article considers the changing political identification of migrants from Japan to North Korea, from 1959 to the 1980s, and their relationship to both the ethnic homeland and the former colonizer. The author suggests that the North Korean state’s effort to contain the imagined threat posed by arrivals from Japan was undermined by transnational exchange between divided families. Specifically, women on both sides of the Sea of Japan (East Sea) engaged in kin work that alerted ethnic Korean immigrants to their ambiguous status as both fraternal comrade and outsider in North Korea. This article illustrates how mobility provided opportunities for new identities to emerge, as individuals who considered themselves Korean compatriots developed identifications that translocally connected them to kin and communities in Japan.

Miscanthus giganteus (M. giganteus) is a promising feedstock for the production of bioethanol or biochemicals. Using only dilute nitric acid, this work describes a two-step process for hydrolyzing hemicellulose and cellulose to fermentable sugars. Primary variables were temperature and reaction time. The solid-to-liquid mass ratio was 1:8. No enzymes were used. In the first step, M. giganteus was contacted with 0.5 wt.% nitric acid at temperatures between 120 and 160°C for 5 to 40 min. The second step used 0.5 or 0.75 wt.% nitric acid at temperatures between 180 and 210°C for less than 6 min. Under selected conditions, almost all hemicellulose and 58% cellulose were transferred to the liquid phase. Small amounts of degradation products were observed. The xylose solution obtained from the nitric-acid hydrolysis was fermented for 96 h and the glucose solution for 48 h to yield 0.41 g ethanol/g xylose and 0.46 g ethanol/g glucose. To characterize residual solids and the liquor from both steps, nuclear-magneticresonance (NMR) spectroscopy was performed for each fraction. The analytical data indicate that the liquid phase from Steps 1 and 2 contain little lignin or lignin derivatives.
