Tectonic provinces in South Korea include the Precambrian Gyeonggi Massif, Palaeozoic Okcheon Belt, Precambrian Yeongnam Massif and Cretaceous Gyeongsang Basin, from northwest to southeast. The Cretaceous strata mainly occur in the Gyeongsang Basin as well as in several small basins along the boundaries of the Okcheon Belt and on the Gyeonggi Massif. This paper reviews and analyses previously published palaeomagnetic data from the Cretaceous successions in South Korea. A total of 23 Cretaceous palaeomagnetic poles, from 18 studies, satisfy more than four standard reliability criteria. The palaeomagnetic pole positions, from the Gyeongsang Basin and from small basins in the Gyeonggi Massif and the Okcheon Belt, are consistent with one another, indicating that the Korean Peninsula has been a single terrane since the Cretaceous. However, based on the comparison of the palaeomagnetic pole positions and the palaeolatitudes of blocks in the Gyeongsang Basin, it was observed that the Gyeongsang Basin had experienced tectonic adjustments during the Cretaceous Period. Within the Gyeongsang Basin, the geographically northern area (Yeongyang block) was rotated counterclockwise by with respect to the southern area (Milyang and Uiseong blocks), based on the comparison of palaeomagnetic pole positions between the two areas. This palaeomagnetic result and some geological features in the Gyeongsang Basin collectively indicate that the Yeongyang block underwent counterclockwise rotations, accompanied by northwestward protrusion, into the Yeongnam Massif during the Late Cretaceous. These relative tectonic movements within the Gyeongsang Basin were probably due to the northwestward subduction of the proto-Pacific oceanic plate during the Late Cretaceous. The gradual eastward displacement of the Korea's Cretaceous palaeopoles, from the Eurasian pole, increases with stratigraphic age, indicating that the Korean Peninsula underwent progressive clockwise rotations, with respect to Eurasia, during the Cretaceous Period. The clockwise rotation of Southwest Japan, with respect to Eurasia, is ascribed to the Miocene opening of the East Sea, and has no connection with the Cretaceous clockwise rotations of the Korean Peninsula, indicating that the Korean Peninsula and Southwest Japan may have been independent terranes during the Cretaceous Period.

Parasterope Kornicker, 1975 is a marine ostracod genus with 49 species described so far, which makes it the most diverse representative of the subfamily Cylindroleberidinae, as well as the entire family Cylindroleberididae. Despite its global distribution no species are reported from South Korea. Three new species collected from the Korean coast of the Sea of Japan (Parasterope busanensis sp. nov., P. singula sp. nov., and P. sohi sp. nov.), and one from the Japanese coast of the Pacific Ocean (P. sagami sp. nov.) are described. A taxonomic key to all named species from East Asia is provided. A phylogenetic tree is reconstructed based on partial 16S rRNA sequences of the four new species and other Cylindroleberidinae available from GenBank. Monophyly of Parasterope is supported by high posterior probabilities, but the phylogenetic analyses also indicate that some of the GenBank data attributed to this genus are probably misidentifications. A map of distribution and a checklist of all described Parasterope species are also provided. [ABSTRACT FROM AUTHOR]

The paper examines heat-related mortality in the population of South Korea between 1991 and 2005 and examines the extent to which the 1994 heat wave was unusual in terms of mortality impacts and recurrence probability. Most summer heat waves are found to be associated with enhanced mortality. However, the July to August 1994 heat wave was clearly exceptional, with the total death toll exceeding 3000 in South Korea. This value represents net excess mortality, as no displacement effect appeared after the hot summer season. Significantly elevated mortality occurred in all age groups, and an estimated 45 % of victims were persons under 70 yr of age. The relative increase in mortality was larger in children up to 14 yr than in any other age group, and the mortality response was stronger in males than females, although males were less vulnerable during 'average' heat waves. The very large death toll ranks the 1994 heat wave over East Asia as among the worst weather-related disasters in this region. A climatological analysis reveals that the July to August 1994 heat wave might be considered an extremely rare event if temperature time series are assumed to be stationary. However, under a more realistic assumption of gradual warming related to global climate change, the recurrence probability of an event analogous to the 1994 heat wave is sharply rising for near-future time horizons. This emphasizes the need for an efficient heat-watch-warning system in this area, in order to reduce the human mortality impacts of heat waves. [ABSTRACT FROM AUTHOR]

This article is part of the special issue Creative Labor in East Asia. By exploring specific politico-economic and institutional, conditions promoting actually existing precarity in Korean digital game labor, this study aims to examine how the industrial and institutional conditions of precarity affect digital game workers' subjectivity. Under this theoretical and empirical consideration, the study first delineates how the rapid industrial transition to the mobile game market happens in relation to the Korean government's deregulation policy on that particular market. It then scrutinizes the ways in which this industrial shift deepens labor precarity, promotes degradation of skills, and ultimately fragments workers in the digital game industry. Based on this structural analysis, it argues that the fragmented industrial structure of the digital game industry in Korea not only actually fosters contrasting labor subjectivities but also promotes fragmented resistances among Korean digital game workers. By critically evaluating both possibilities and limitations of the recent firm-centered union movements created by digital game workers, the study ultimately concludes that finding a way to connect organized unions to unorganized freelance workers is absolutely necessary to actually transform "precarity" into "solidarity."

Although 30 years have passed since the ASEAN-Korea dialogue partnership began, the two sides' political and security relations remain irregular and limited. Although such limits have been widely recognized, they have rarely been examined comprehensively. This study aims to address this gap by focusing on Korean executive leadership as key diplomatic actors who are shaping an inconsistent and distant partnership with ASEAN. The findings show that the executives' changing conceptualizations of the regions and the approaches to regional security with limited agency independence in the bureaucracy have been major obstacles to finding a reliable common ground for institutionalizing cooperation with ASEAN.

This is the first record of the genus Typhlocolenis Hoshina, 2008 (Coleoptera, Leiodidae, Leiodinae, Pseudoliodini) in South Korea. Two new Korean species are described, under the names T. sillaensis sp. nov. and T. jejudoensis sp. nov. As a result of this study, the number of Typhlocolenis species is now five. A key to the species of the genus is provided. [ABSTRACT FROM AUTHOR]

American bullfrog Rana catesbeiana Shaw, 1802 (= Lithobates catesbeianus) is one of the world's most problematic amphibians. In both 1957 and 1973, the species was introduced to the Republic of Korea, in order to be bred as a food resource. However, after breeding efforts failed, the breeders illegally released the frogs into the wild. Now, about 50 years later, the species is distributed throughout the nation. The aim of our study was to document the distribution of R. catesbeiana throughout the Republic of Korea by analyzing several nationwide surveys. The species was reported to occur at 2,716 sites, mainly along the southern and western coasts, but was rarely distributed in the northern part of Korea or along the eastern coast. Further studies are needed to elucidate the effect of R. catesbeiana on the native ecosystems. [ABSTRACT FROM AUTHOR]

A new interstitial species, Caecianiropsis goseongensis sp. n. is described from littoral off the east coast of Korea (Sea of Japan). The species can be distinguished from its congeners by the number of antennular articles, shape of the male appendix masculina, setation of pereopods, and length ratio of the uropodal rami. To aid species identification a taxonomic key to all species of Caecianiropsis Menzies & Pettit, 1956 is also provided as well as a partial 16S mitochondrial ribosome RNA of the new species, which is the first genetic information for the genus.

Redistributive land reforms implemented in post-WWII Japan, South Korea, and Taiwan have often been considered a substantial stimulus for these countries' subsequent economic growth. Before the reforms, there were a small number of large landlords and many small tenant cultivators, but after the reforms, tenancy effectively disappeared. This article assesses the impact of reforms on structural change and income per capita, and shows that reforms were responsible for at least half of the actual reallocation of labor out of agriculture in each of these countries in the aftermath of the reforms. By contrast, their impact on income per capita was small. [ABSTRACT FROM AUTHOR]

Environmental aid has become a major component of development aid. We analyzed the contingent characters of environmental aid of Japan and South Korea using the definition of Williams, which regards aid policy as donor driven and autobiographical of the donor agencies and societies from which they sprang. Both Japan and South Korea consider environmental aid as an important tool of their diplomacy. A combination of a moral obligation and domestic, international, political, and economic interests underpin both countries’ environmental aid policy. Seen from the stated policies and practices, both countries use accounts of their past as once-developing countries trying to catch up in their aid narrative. In this manner, the environmental aid of Japan and South Korea is autobiographic, reflecting their interpretation of their own development history and position in global politics.

This article examines the sources and consequences of East Asia's participation in global governance. Despite the rhetoric of global contribution, the article argues that global governance issues are reframed in East Asia to better suit domestic and regional priorities. Specifically, two underlying mechanisms are at work to complicate, and often render ineffective, East Asia's foray into global governance: (1) the conflicting identities of the three countries at the regional and global levels; and (2) the localization of global governance issues. By examining the global role of China, Japan, and South Korea in climate change, peacekeeping, nuclear nonproliferation, the article shows how the shared desire of enhancing global status in East Asia is tempered by the politics of dual identity and issue localization.

This article compares and explores forms of ‘public’ participation in the development of bioethical governance of human embryonic stem cell research (hESR) in four Asian societies, and in doing so it contributes to the wider discussions on expertise and public inclusion. The article aims to add nuance to the concept of ‘public consultation’ by focusing on the contested meanings and relationships through which public roles and public debates are defined. The analysis seeks to go beyond a straightforward comparison by interpreting public discussions of hESR as being influenced by both local conditions and interconnected global science institutions. An adequate understanding of the public participation in debates on science requires the analysis of (a) particular reasons for scientific issues to require public discussion; (b) pressures of transnational forces; (c) variability of publics relevant to bioethical regulation; and, (d) the effects of institutionalization of bioethics. This study uses data from fieldwork conducted between 2006 and 2010 in four Asian countries. Most of the interviews were conducted in the local languages and concerned various kinds of public participation in bioethics activities, as well as the views of stem cell scientists on the need to involve the public in discussions on the acceptability of their research.

Despite progressing global warming, extreme cold events in East Asia are still occurring frequently with temperature variability enhanced. To understand this situation, it is necessary to determine external and internal climatic factors and their modulation effects that influence regional temperature variability. We found that the positive correlation between Arctic Oscillation (AO) and surface air temperature (SAT) in South Korea during winter is modulated strongly by tropical influences associated with El Niño Southern Oscillation (ENSO). In the case of a negative (positive) SAT anomaly in South Korea during the positive (negative) AO phase, a state that is opposite to the typical relationship between AO and SAT, the tropical sea surface temperature shows a typical negative (positive) ENSO-like pattern. The atmospheric teleconnection associated with the negative (positive) ENSO conditions contributes to a deepening (flattening) of the climatological East Asian trough and an enhancing (weakening) of the East Asian jet, which leads to negative (positive) SAT anomalies in South Korea. This modulation effect is robustly observed in the historical simulations of three different models of CMIP5. [ABSTRACT FROM AUTHOR]
