A major purpose of a scientific meeting is the exchange of information. Traditionally, authors have preferred to present their research in an oral format. However, poster presentations are becoming more popular every year. Today, poster and oral presentation are recognized as being of equal status, Regardless of which format you select, remember that the poster or oral presentation must he carefully planned, clear and concise, oriented to transfer information effectively, and hold the attention of the learner.

Objectives: The aim of this study was to determine the rate of peer-reviewed publication of abstracts presented at the annual meetings of the Turkish Association of Oral and Maxillofacial Surgeons (TAOMS) and to identify the time to publication, subspecialty, and study design. Materials and Methods: All abstracts accepted for presentation at a TAOMS meeting between 2007 and 2009 were identified from a book of abstracts and were searched for publication using PubMed and Google Scholar. The following variables were evaluated: publication rate, type of presentation (oral or poster), time to publication, subspecialty, study design, and name of the journal in which the article was published. Results: A total of 478 abstracts were presented at the TAOMS meetings between 2007 and 2009. Of these, 140 abstracts (29.3%) were subsequently published in peer-reviewed journals, including 38.2% of oral presentations and 26.6% of poster presentations. The mean time from presentation to publication was 22 months. Regarding publication fields, research and emerging technologies presentations had the highest publication rate (100%). With regard to study type, animal study (70.0%) and basic research (55.0%) had the highest publication rates. Conclusion: Only 29.3% of abstracts presented at the TAOMS meeting were subsequently published as full-text articles. This rate was found to be similar to the previously reported publication rates in the field of oral and maxillofacial surgery.

The purpose of this paper is to examine the effectiveness of presentation-based instruction and to suggest a model of instruction targeted to the Korean intermediate level students learning English as a foreign language (EFL). To achieve this objective, the author examined how the acquisition of practical English through oral presentation would enhance the students' learning motivation, language abilities, and communicative competence in concrete situations. It was confirmed that the trained leader and systematic teaching and learning are needed to maximize the effects of presentation-based instruction. In doing so, the author compared and analyzed the collected data in order to support the validity of this teaching method. It was further pointed out that the teacher should have a close look at the roles of the presenter and learner in an effort to work out the usefulness of such an instruction model. The method of presentation in classroom settings would be a practical mode to attain the essential purpose of EFL teaching particularly to get over the drawbacks of Korean students' communicative competence. As a result, it would be an effective teaching method to meet the nation's long-standing demands for EFL education.

DCs, like the sensory neurons, express vanilloid receptor 1 (VR1). Here we demonstrate that the VR1 agonists, capsaicin (CP) and resiniferatoxin (RTX), enhance antiviral CTL responses by increasing MHC class I-restricted viral antigen presentation in dendritic cells (DCs). Bone marrow-derived DCs (BM-DCs) were infected with a recombinant vaccinia virus (VV) expressing OVA (VV-OVA), and then treated with CP or RTX. Both CP and RTX increased MHC class I-restricted presentation of virus-encoded endogenous OVA in BM-DCs. Oral administration of CP or RTX significantly increased MHC class I-restricted OVA presentation by splenic and lymph node DCs in VV-OVA-infected mice, as assessed by directly measuring OVA peptide SIINFEKL-K^b complexes on the cell surface and by performing functional assays using OVA-specific CD8 T cells. Accordingly, oral administration of CP or RTX elicited potent OVA-specific CTL activity in VV-OVA-infected mice. The results from this study demonstrate that VR1 agonists enhance anti-viral CTL responses, as well as a neuro-immune connection in anti-viral immune responses.

Individuals with human immunodeficiency virus (HIV) infection present with unique intraoral manifestations of various neoplasms. Intraoral HIV-associated Burkitt's lymphoma is a rare presentation, especially in patients of Indian origin and may present as an initial sign of HIV. The objective of this paper is to report a rare case of Burkitt's lymphoma in an HIV-positive Indian patient along with a special emphasis on differential diagnosis. A 30-year-old Indian female presented with a solitary, well-defined, exophytic mass extending anteroposteriorly and buccolingually from the 35th to 38th regions with no evidence of intraosseous extension. An incisional biopsy was performed, and histopathology showed sheets of neoplastic lymphoid cells with numerous tingible body macrophages with clear cytoplasm, presenting a starry sky appearance, suggesting a diagnosis of BL. The tumor cells were positive for CD10, CD20, c-myc, and Epstein-Barr virus, with a nearly 100% Ki-67 proliferative index. The patient tested positive for HIV. This report indicates the importance of immunohistochemical analysis to differentiate Burkitt's lymphoma from other similar lesions like diffuse large B-cell lymphoma. Thorough knowledge of the clinical presentation, etiopathogenesis, histopathology, and immunoprofile of intraoral HIV-associated Burkitt's lymphoma is essential among clinicians and pathologists.

The purpose of this study is to investigate the involvement strategies in presentation discourse of Korean native speakers and to compare strategies in presentation of Korean learners and international graduate students with that. For this study, the presentation discourse of 13 Korean undergraduates, 21 Korean graduate students, 6 Korean advanced learners, 8 international graduate students was analyzed. The results of the study showed that Korean native speakers used many types of involvement strategies such as conversing, expressing solidarity, expressing closeness. Asking questions to audience was a representative type of conversing. And expressing solidarity was divided using 'we' and sharing experience. expressing closeness was also divided insertion of personal cases and joking. On the other hand, Korean learners and international graduate students used simple types of involvement strategies. Based on these results, I have proposed a few teaching ways for involvement strategies.
