Early-Age Properties of Polymer Fiber-Reinforced Concrete

Myers, Daniel,Kang, Thomas H.K.,Ramseyer, Chris Korea Concrete Institute 2008 International Journal of Concrete Structures and M Vol.2 No.1

The cracking problem in concrete is widespread and complex. This paper reviews the problem and focuses on those parts of the problem that are more readily solved. Polymer fibers are shown to have promise in several important areas of the cracking problem. To investigate one of these areas of the cracking problem more completely, an experimental research program focusing on the early-age properties of fibers was carried out. This study researched the properties of four polymer fibers; two of the fibers were macrofibers, and two were microfibers. Each fiber was tested at several dosage rates to identify optimum dosage levels. Early-age shrinkage, long-term shrinkage, compressive strength, and tensile strength were investigated. Long-term shrinkage and strength impacts from the polymer fibers were minimal; however, the polymer fibers were shown to have a great impact on early-age shrinkage and a moderate impact on early-age strength.

Inflammatory production of reactive oxygen species by <i>Drosophila</i> hemocytes activates cellular immune defenses

Myers, Amber L.,Harris, Caitlin M.,Choe, Kwang-Min,Brennan, Catherine A. Elsevier 2018 Biochemical and biophysical research communication Vol.505 No.3

<P><B>Abstract</B></P> <P>The production of reactive oxygen species (ROS) is a prominent response to infection among innate immune cells such as macrophages and neutrophils. To better understand the relationship between antimicrobial and regulatory functions of blood cell ROS, we have characterized the ROS response to infection in <I>Drosophila</I> hemocytes. Using fluorescent probes, we find a biphasic hemocyte ROS response to bacterial infection. In the first hour, virtually all hemocytes generate a transient ROS signal, with nonphagocytic cells including prohemocytes and crystal cells displaying exceptionally strong responses. A distinct, and more delayed ROS response starting at 90 min is primarily within cells that have engulfed bacteria, and is sustained for several hours. The early response has a clear regulatory function, as dampening or intensifying the intracellular ROS level has profound effects on plasmatocyte activation. In addition, ROS are necessary and sufficient to activate JNK signalling in crystal cells, and to promote JNK-dependent crystal cell rupture. These findings indicate that <I>Drosophila</I> will be a promising model in which to dissect the mechanisms of ROS stimulation of immune activation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Biphasic hemocyte ROS response to infection in flies. </LI> <LI> Early response high in non-phagocytic prohemocytes and crystal cells. </LI> <LI> Delayed ROS in phagocytic cells. </LI> <LI> ROS activate plasmatocyte spreading and adhesion. </LI> <LI> ROS promote JNK-dependent crystal cell rupture. </LI> </UL> </P>

Microsurgery Training for the Twenty-First Century

Myers, Simon Richard,Froschauer, Stefan,Akelina, Yelena,Tos, Pierluigi,Kim, Jeong Tae,Ghanem, Ali M. Korean Society of Plastic and Reconstructive Surge 2013 Archives of Plastic Surgery Vol.40 No.4

Current educational interventions and training courses in microsurgery are often predicated on theories of skill acquisition and development that follow a 'practice makes perfect' model. Given the changing landscape of surgical training and advances in educational theories related to skill development, research is needed to assess current training tools in microsurgery education and devise alternative methods that would enhance training. Simulation is an increasingly important tool for educators because, whilst facilitating improved technical proficiency, it provides a way to reduce risks to both trainees and patients. The International Microsurgery Simulation Society has been founded in 2012 in order to consolidate the global effort in promoting excellence in microsurgical training. The society's aim to achieve standarisation of microsurgical training worldwide could be realised through the development of evidence based educational interventions and sharing best practices.

Combined CD137 (4-1BB) and adjuvant therapy generates a developing pool of peptide-specific CD8 memory T cells

Myers, Lara,Lee, Seung Woo,Rossi, Robert J.,Lefrancois, Leo,Kwon, Byoung S.,Mittler, Robert S.,Croft, Michael,Vella, Anthony T. Oxford University Press 2006 International immunology Vol.18 No.2

<P>In practice, vaccines should induce lasting and efficacious T cell immunity without promoting deleterious pathological consequences. To accomplish this goal we immunized mice with ovalbumin peptide, polyinosinic–polycytidylic and anti-CD137. Vaccinated mice retained a massive functional CD8 T cell memory pool in lymphoid and non-lymphoid tissues for >1 year. The memory T cells clonally expanded, produced substantial amounts of IFNγ, and responded vigorously to vesicular stomatitis virus infection. To understand how the vaccine might function, we showed that the antigen-specific T cells must bear CD137 in order for optimal priming to occur. Thus, anti-CD137 agonist mAb directly stimulated peptide-specific CD8 T cells and conditioned them to survive. In contrast, CD137-deficient CD8 T cells did not survive despite CD137 expression by antigen presenting cells. Taken together, the data indicate that CD137 and adjuvant combined therapy is an efficacious vaccine strategy for immunization with non-replicating inert antigen.</P>

INNOVATIVE STRATEGIES FOR COMPARATIVE AGING RESEARCH

MYERS, GEORGE C. Institute for Social Development and Policy Resear 1995 Korea Journal of Population and Development Vol.24 No.2

After introductory comments on the theme of ‘ageing east and west’, this paper looks at trends in ageing and responses to ageing over time, with particular reference to European experience. The evidence is reviewed in historical, cultural, religious, political and ‘social political’ perspective. Attention in drawn to the different patterns of experience and of policy responses characteristic of the different countries and regions within Europe both past and present. The paper concludes with a review of latest trends and prospects in ‘community care’, which could signal a seeming point of convergence between east and west.

“Kim Jong Il Mania”: The Depiction of South Korea in Contemporary North Korean Propaganda

Brian Myers 사단법인 한국평화연구학회 2006 평화학연구 Vol.7 No.2

The Sunshine Policy puts Kim Jong Il in a difficult position. He cannot inform his people that the South Korean government wants peaceful reconciliation, because this would be tantamount to admitting that it is not a Yankee puppet after all. Such an admission would in turn undermine his own regime’s claim to exclusive legitimacy. But neither can his propaganda apparatus act as if nothing has changed. The problem is solved as follows: On the one hand, the Korean Central News Agency and the Rodong sinmun newspaper refrain from direct attacks on the Blue House, thus conveying to the South the superficial impression of a Sunshine-induced “thaw.” At the same time, less prominent propaganda sources seek to reconcile the new reality of North-South exchanges with the orthodox view of the South as a Yankee puppet. The following paper examines Kim Nam-ho’s Encounter (Mannam, Pyongyang, 2001). The novel portrays Kim Dae Jung as an anti-communist who goes to the June 2000 summit in Pyongyang in bad faith, intent on making the North renounce socialism. Instead, the General’s charisma and genius daze the phony “president” into accepting his demands for inter-Korean cooperation. The South Korean masses then give themselves over to Kim Jong Il Mania, an outpouring of support so fervent that the “president” dares not renege on the June 15 declaration. Thus does the summit – which the novel calls a summit between Kim Jong Il and the South Korean people – usher in a new era of hope. The paper examines the novel’s message and Pyongyang’s motivation for propagating it, and also draws attention to the contrast in the tones in which the two Koreas now talk of each other. This contrast undermines Seoul’s assertions that the Sunshine Policy has built bilateral trust. The conclusion of the paper warns that propaganda creates an atmosphere that influences the propagandists themselves. Claims of frenzied South Korean support for Kim Jong Il could well encourage Pyongyang to lapse into the military adventurism of old. The Sunshine Policy puts Kim Jong Il in a difficult position.

Yeats Matters : Iconic Value and Visibility

Nathan Myers 한국예이츠학회 2015 한국예이츠 저널 Vol.47 No.-

많은 정경화된 문인들과 달리, 윌리엄 버틀러 예이츠는 학자들과 대중매체의 창작인들에게 호기심과 다양한 관점으로서 영속적이다. 예이츠 인용, 언급, 환기는 시간, 장소, 장르를 초월하며, 그 양과 지속성은 예이츠는 영원하다는 것이다. 그의 이름은 권위적이고, 영속적이고, 특이하게 변하는 자산이다; 그의 문학적 특성은 작가들에게 도움과 자료가 된다. 이것은 지난 반세기 동안의 점차 지구화되는, 범국가적 문화의 기억 속에서 예이츠의 뛰어나고 변화무쌍한 지위를 동시에 활용하고, 주장하고, 영속화시키는, 뚜렷하지만, 애매하게 정의된, 역사적으로 대중적이면서도 도회적인, 문학전통과 맥을 같이한다. 세기말 사이드와 키버드의 예이츠의 정치적 면모를 (재)조명함으로써, 리처드 엘만이 조지 예이츠와의 관계를 설명함으로써, TV와 영화 속의 예이츠의 등장을 통해서, 나는 예이츠의 시와 개성이 어떻게 20세기를 넘어서 국가적, 종족적, 사회적 힘에 관한 복잡한 개념들과 얽혀있는지를 탐구한다. Unlike many canonized literary figures, William Butler Yeats endures as a curious and multifarious point of reference for both the academic community and purveyors of more popular media. Yeats allusions, references, and evocations span time, location, and genre, but their volume and consistency clearly indicate that Yeats matters. His name retains an authoritative, enduring, and uniquely protean capital; his literary signature aids the writer and affords resources, aligning it with a distinctive, though vaguely defined, literary tradition, historically popular and urbane, that simultaneously exploits, asserts, and perpetuates Yeats’s eminent and mutable position in the increasingly globalized, transnational cultural memory of the last half century. Through discussions of Richard Ellmann’s relationship with George Yeats, Yeats’s (re)politicization by Said and Kiberd near the end of the century, and Yeats’s appearances in television/film, I explore how Yeats’s poetry and personage have been tangled in complex notions of national, ethnic and social power across the 20th century.

Constructing English Language Learners as Intercultural Speakers through Digital Technologies

Jamie Myers 영상영어교육학회 2007 영상영어교육 (STEM journal) Vol.8 No.1

This article introduces various theories that support a goal for English language learning as the production of critical intercultural speakers through digital multimedia activities in the English as Foreign Language Classroom. The existing research and theory draws from the scholarly fields of Applied Linguistics, Socio-cultural Philosophy and Language, Anthropology, and Language and Literacy Education. These theories highlight a close connection between the definitions of critical literacy in first language education and the definitions of intercultural speakers in English as a second language education. Additional theories about new literacies and technology in addition to research studies with students in grades 7-12 and university undergraduates and graduate students illustrate how the goal of critical intercultural speakers can be achieved through multimedia digital technologies. Specific instructional projects with English language learners described include the multimedia activities of website authoring, podcast audio recording, and online asynchronous discussion. Three common characteristics of language learner activity across these multimedia instructional events are 1) the use digital tools to represent cultural identities and practices, 2) the reflection on identities, relationships, and values especially as they are constructed and positioned through media communications, and 3) the development of critical thinking and critical voices to enable students to speak global Englishes within authentic communicative contexts.
