  • Diaspora studies has become one of the fastest growing field in the humanities over the past several decades, and the use of term diaspora has been widening to include almost any population on the move. Diaspora literature not only mirrors but actively incorporates this new notion of diaspora with characters "at the threshold" navigating new territories and identities. Querying how diaspora studies intersects with theatre and performance, this paper attempts to probe how recent Korean American drama parallels and promotes diaspora studies' radical departure from traditional notions of identities and territories. For this purpose, this essay 1) examines theoretical affinities between diaspora studies and performance studies 2) investigates how Sung Rno's plays, Cleveland Raining and wAve, explore and embody multiple and evolving meanings of Korean diaspora on the stage 3) examines how theatre can create the third space that transcends both Korean and American nationalism and 4) speculates possibilities of reframing Asian American Studies as Asian diaspora studies. Korean American characters in Rno's play redirect diasporic identities, as their concern gradually moves from "where I come from" to "where I go to." Instead of remaining in the dark as a mere spectator, both Rno and his characters choose to be 'on' the stage where they can imagine, perform, and realize (however temporarily) "unimaginable community" by confronting their own social, political, and cultural ambivalence. Stage, the threshold between reality and fiction, Korea and America, and past and future, becomes their true 'home' where they incubate and precipitate "nation in transformation" that Yan Haiping argues for as "another transnational."

  • The purpose of this review is to examine the performance of attachments used in implant-supported overdenture (IOD) in both clinical and in vitro settings and report the compiled findings, comparisons, and trends in the research literature. Articles published in PubMed on IOD attachment systems and performance were reviewed. Non-original articles were excluded. For each article included, the type of study, number of implants, number of attachment systems, and study outcome were recorded. Of the 283 articles found, 158 met the inclusion criteria. Ninety-four articles were clinical studies and 64 articles were in vitro studies. Studies on retention were the most common for in vitro studies, and four or more attachment systems were compared in most articles with significant differences in outcome. A clinical outcome of one attachment system was most common for clinical studies, while most studies had neutral outcomes overall. Ball attachment was the most commonly tested IOD attachment system. The trend in the literature showed that there is a large discrepancy between the study designs and outcomes between the clinical and the in vitro studies for IOD. Further clinical studies that can validate in vitro research should be encouraged to address this discrepancy between the two areas.

  • An efficient and productive R&D operation is a major source of competitive advantage in today's economy, and a lot of efforts are made to raise R&D productivity. A prerequisite for making R&D more efficient and productive is to be able to measure it. Hence, a number of studies have attempted to measure R&D productivity. R&D productivity, in the previous studies, was measured with patents at the firm or industry level. However, most previous studies considered only a quantitative aspect, not a quantitative aspect of patents. In this study, various dimensions of patent quality as well as patent quantity were considered for the measurement of R&D performance. The differences in R&D performance across sectors were examined, and it was found that electrical/electronic industry shows higher R&D performance than mechanic and chemical industries. Discriminant analysis based on inputs and outputs for R&D shows' that there exist a strong discriminatory power across industries. The results of this research can provide the directions 'for the firm's R&D policy.
