Yeungnam University is a private research university, located in Gyeongsan, North Gyeongsang, South Korea. The university's predecessors, Taegu College and Chunggu College, were founded in Daegu in 1947 and 1950 respectively. In 1967, the two colleges merged by President Park Chung-hee to form the degree-granting Yeungnam University. In 1972, the university's new main campus opened in Gyeongsan east of Daegu. The university includes colleges of Law and Medicine and a teaching hospital. Wikipedia.

Aphasia is one of the most common and devastating sequelae of stroke. The arcuate fasciculus (AF), an important neural tract for language function, connects Broca's and Wernicke's areas. In this review article, previous diffusion tensor imaging (DTI) studies on the AF in stroke patients were reviewed with regard to the usefulness for diagnosis (seven studies), prediction of prognosis (two studies), and recovery of aphasia (three studies). Although scant studies on this topic have been conducted in stroke patients, DTI for the AF appears to provide useful information on the presence or severity of injury of the AF, prognosis prediction of aphasia, and recovery mechanisms of aphasia in stroke patients. Therefore, further DTI studies on these topics should be encouraged, especially studies on prognosis prediction and recovery mechanisms of aphasia. In addition, research on other neural tracts known to be involved in aphasia as well as the AF in both hemispheres should be encouraged. © 2013 Jang.

The death domain (DD), which is a versatle protein interaction module, is the prime mediator of the interactions necessary for apoptosis, innate immunity and the necrosis signaling pathway. Because DD mediated signaling events are associated with critical human diseases, studies in these areas are of great biological importance. Accordingly, many biochemical and structural studies of DD have been conducted in the past decade to investigate apoptotic and innate immune signaling. Evaluation of the molecular structure of DD and their interactions with partners have shown the underlying molecular basis for the assembly of DD mediated complexes and for the regulation of apoptosis and innate immunity. This review summarizes the structure and function of various DDs and DD:DD complexes involved in those signaling pathways. © 2010 Springer Science+Business Media, LLC.

There is a burgeoning interest among social scientists in the development of e-science technologies and research practices around world. However, the international social science research literature has not systematically examined e-science approaches in Asia in general and Korea in particular. This article presents empirical findings from a webometrics analysis of the semantic variation, disciplinary scope, and institutional structure of e-science programs in South Korea. The findings suggest that some e-science terms, including cyberinfrastructure, have prominent Korean web presences. At the same time, Korean government-sponsored national e-science centers and their affiliates do not have a strong web presence and do not actively participate in the hyperlink network that connects e-science-related institutional websites. Instead, they have a closed network among themselves. This result stems from the institutional dynamics within Korea's public and private e-science research communities. © 2010 International Communication Association.

To efficiently support automated interoperability between ontology-based information systems in distributed environments, the semantic heterogeneity problem has to be dealt with. To do so, traditional approaches have acquired and employed explicit mappings between the corresponding ontologies. Usually these mappings can be only obtained from human domain experts. However, it is too expensive and time-consuming to collect all possible mapping results on distributed information systems. More seriously, as the number of systems in a large-scale peer-to-peer (P2P) network increases, the efficiency of the ontology mapping is exponentially decreased. Thereby, in this paper, we propose a novel semantic P2P system, which is capable of (i) sharing and exchanging existing mappings among peers, and (ii) composing shared mappings to build a certain path between two systems. Given two arbitrary peers (i.e., source and destination), the proposed system can provide indirect ontology mappings to make them interoperable. In particular, we have focused on query-based communication for evaluating the proposed ontology mapping composition system. Once direct ontology mappings are collected from candidate peers, a given query can be (i) segmented into a set of sub-queries, and (ii) transformed to another query. With respect to the precision performance, our experimentation has shown an improvement of about 42.5% compared to the keyword-based query searching method. © 2010 Elsevier Inc. All rights reserved.

Many studies on folksonomy analysis have focused on discovering meaningful patterns between three main entities (i.e., users, tags, and resources) from a folksonomy system to provide various information services to users. However, most of them have simply assumed that the tags in the folksonomy are written in a same language, i.e., any tags can be compared with others. In this work, multilingual folksonomies are focused to discover useful matchings between multilingual tags (e.g., among 'Korea' in English, Coréia in Portuguese and 'Corée' in French). Moreover, such matchings can be applied to expand user queries to retrieve additional resources tagged by the other languages. We focus on analyzing a multilingual folksonomy generated by various lingual practices of online users, and discovering meaningful relationships between multilingual tags (e.g., between 'Seoul' in English and 'Corée' in French) co-occurred in the folksonomy. Thereby, we propose novel methods for (i) identifying lingual practices from user tagging patterns to build community of lingual practice and (ii) exploiting the tag matchings to extend simple term-based queries. Thus, additional resources tagged by other languages can be retrieved. To evaluate the proposed multilingual tag matching method, we have collected real tagging datasets from several well-known social tagging websites (e.g., Del.icio.us), and applied to translating queries to other languages without any external dictionaries. © 2013 Elsevier B.V.
