네트워크 통신을 기반으로 한 영상 회의 및 세미나, 강의에서는 영상/음성뿐만 아니라 프리젠테이션 제시 또한 중요한 요소로 작용하고 있다. 전형적인 세미나 또는 회의, 강의에서 사용되는 흑판을 촬영하여 영상 전송 기능을 그대로 이용하는 프리젠테이션 제시 기법은 고해상도의 영상 기술이 필요하고, 촬영기술의 기능까지 요구되므로 원격의 환경에서 큰 장애 요인이 된다. 본 논문에서는TCP기반의 연결 지향형 소켓을 이용한 효과적인 멀티미디어 프리젠테이션을 공유하기 위한 실시간 멀티미디어 공유 보드시스템을 구현한다. 이 시스템은 시스템 구축에 수반하는 비용을 감소할 수 있으며 데이터 신뢰성 및 상호 작용을 향상시키고, 프리젠데이션 지연 시간을 최소화할 수 있다.

발표자의 적극적인 역할과 개입은 정보시각화를 효과적으로 표현하고 전달하는 핵심 요인임에도 불구하고, 정보 시각화 연구에서 적극적으로 다루어지지 못했다. 단순히 시각화 결과만 보여주는 것이 아니라, 발표자가 시각화와 관련된 부가적인 정보 및 맥락을 함께 제공함으로써 시각화 전달 과정을 증진시킬 수 있다. 본 논문에서는 발표자가 3차원 시각화 공간에 직접 개입하여 자신을 둘러싼 공간에 표현된 정보와 직접적으로 상호작용 하면서, 정보 표현 및 전달 과정을 적극적으로 증진시킬 수 있는 방식을 제시하고 이를 증강 프레젠테이션 (augmented presentation)이라는 프레임워크로 정의한다. 증강 프레젠테이션의 특성을 구체화하기 위해서 발표자가 개입할 수 있는 시각화 공간을 디자인하고, 발표자로 하여금 관찰자와 정보 간의 의사소통 과정을 충분히 지원할 수 있도록 발표자의 역할을 화자(storyteller), 제어자(controller), 정보증강자(augmenter)로 정의했으며, 그들의 역할 가능성을 제안하였다. 또한, 증강 프레젠테이션 특성을 실제로 구현할 수 있는 프로토타입 시스템을 제작하였다. 하프미러 필름 (half-mirror film)과 일반 프로젝션 스크린을 일정 간격을 띄운 후 평행하게 위치시키고, 각 스크린에 입체 영상을 적용한 후, 발표자가 스크린 사이에 표현된 3차원 시각화 공간 내에 직접 개입하여 정보와 상호작용할 수 있는 형태이다. 이후, 초기 단계에서 몰입적 정보 표현과 정보 전달 플랫폼으로서 증강 프레젠테이션의 가능성을 확인하기 위해서 기존의 프레젠테이션 시스템과 증강 프레젠테이션 시스템을 비교하는 예비 실험 (pilot test)을 진행하였다. 그 결과, 본 연구에서 제시한 증강 프레젠테이션은 실제 3차원 공간에서 가상의 정보와 실제 발표자를 자연스럽게 통합시켜 표현함으로써 몰입적이고 관찰자의 주의를 사로잡는 프레젠테이션을 실현할 수 있는 가능성이 충분히 있음을 확인했다.

Cordyceps militaris, a traditional medicinal mushroom, produces a component compound, cordycepin (3'-deoxyadenosine). Cordycepin has many pharmacological activities including immunological stimulating, anti-cancer, and anti-infection activities. However, the therapeutic mechanism has not yet been elucidated. In this study, we examined the effects of cordycepin on the antigen-presenting function of antigen-presenting cells (APCs). Dendritic cells (DCs) were cultured in the presence of cordycepin and then allowed to phagocytose microspheres containing ovalbumin (OVA). After washing and fixing, the efficacy of OVA peptide presentation by DCs was evaluated using CD8 and CD4 T cells. Also, we confirmed the protein levels of proinflammatory cytokines through RT-PCR and Western blot analysis. Cordycepin decreased both MHC class I and class II-restricted presentation of OVA and suppressed the expression of both MHC molecules and the phagocytic activity toward exogenous OVA. The class II-restricted OVA presentation-regulating activity of cordycepin was also confirmed using mice that had been injected with cordycepin followed by soluble OVA. Furthermore, cordycepin suppressed the mRNA and protein levels of iNOS, COX-2, pro-inflammatory cytokines in a concentration-dependent manner. These results provide an understanding of the mechanism of the T cell response-regulating activity of cordycepin through the inhibition of MHC-restricted antigen presentation in relation to its actions on APCs.

A four-year-old female Pekingese dog was presented with intermittent ambulatory hindlimb lameness and severe back pain. The course of the disease was acute and static and 5 days passed by until presentation. In neurological examination, severe back pain and slightly decreased proprioception in right hindlimb were shown. In radiographic examination, radiopacity was increased at T10-11 intervertebral disc space. According to the history taking, neurological examination and radiographic examination, it was tentatively diagnosed as intervertebral disc disease (IVDD). Conservative treatment was performed including cage rest, medication with prednisolone and traditional acupuncture. Acupoints were GV-6, GV-7, BL-18, BL-19. BL-40 and GB-34. Dry needlings rested for 20 minutes. Just after the first acupuncture treatment back pain was significantly decreased. With additional acupuncture treatment, all the clinical signs were not observed. It is considered that conservative therapy including traditional acupuncture, medication and cage rest might be the first choice of therapeutic method for Grade I or II IVDD in dogs.

With the development of Internet and transition to information society, social capital is expanding to online from the traditional offline context. Especially with the widespread of social network service(SNS) the number of SNS users is increasing sharply and the importance of online social capital has been more and more significant. Most studies on social capital focused on organizational aspects but few studies have payed attention to personal aspect. Empirical studies on the relation between SNS and social capital were seldom conducted in previous studies. Based on the theory of social capital this study targets on the relationship formed through SNS and analyzes on how the relationship affects the perceived social capital. In this study 'self-presentation', 'playfulness' and 'critical mass' are posited as the antecedent factors of 'SNS usage'. This study proposes a research model to examine the effect of 'SNS usage' on 'relationship reinforcement', 'relationship building' and 'perceived social capital'. According to the results of empirical analysis, 'self-presentation', 'playfulness' and 'critical mass' can generate significant positive influence on 'SNS usage'. It also confirms not only the effect of 'relationship reinforcement' and 'relationship building' formed through SNS on 'perceived social capital' but also relationship between the social capital formation and SNS usage. The outcome obtained in this study can be applied in developing SNS services.

This article is to investigate the possibility that project-based classes introducing mobile phones can replace the monotony of traditional classes led by teachers as well as they can encourage students to take active part in the classes to some extent. The students in groups choose a genre for their own video projects (e.g., movie, drama, news, documentary, and commercial) and produce the video contents using a mobile phone for presentation made at the end of a semester. In the sense that the students are allowed to do video-based mobile phone projects, they can work independently outside of class, where time and space are more flexible and students are free from the anxiety of speaking or acting in front of an audience. A mobile phone project consists of around five stages done both in and outside of the classroom. All of these stages can be graded independently, including genre selection, drafting of scripts, peer review and revision, rehearsals, and presentation of the video. Feedback is given to students. After the presentation, students filled out a survey questionnaire sheet devised to analyze students' responses toward preferences and level of difficulty of the project activity. Finally, proposals are made for introduction of a better mobile phone-based project classes.

This study investigated natural aroma fragrance on the fashion image of Galchon, a traditional natural dyeing textile made with immature persimmon from the Jeju area, Korea. Nine fabric pairs consisting of differently colored cotton and silk Galchon with various tones and fabric types were used for subjective evaluation. Thirty five female college students evaluated the specimens using a 7-point scale questionnaire for fashion image-related adjectives. A specimen with three different presentation types that included fabric without fragrance (FO), fabric with citrus fragrance, and fabric with chamaecyparis (FCP) were randomly provided to a subject. As a result, color variables of Galchon were found to be the primary influence on fashion images for both cotton and silk Galchon that showed interaction effects with presentation types. The citrus fragrance increased the feeling of 'Active' while chamaecyparis tended to contribute to a stronger perception of 'Elegance' for cotton Galchon. Finally, these results were used to develop prediction models for fashion images of Galchon that employed color variables and presentation types.

This study explores perspectives on responding to EFL students' compositions at the semantic level. In the last three decades, there has been a shift from product-oriented approach to process-oriented one to teaching writing. The shift has led to the criticism of the traditional view on teacher response. The traditional view has been under attack for its overemphasis upon form and ineffectiveness on improving student writing skill. It is also noted that research into students' reactions to the traditional teacher response has been inconclusive. The process-oriented approach, on the other hand, draws its attention to meaning and the logical development of thought as well as linguistic matters. In this context, the present study discusses what EFL teachers need to take into account in providing the semantic-level feedback on students' compositions. Firstly, teacher response to student writing is on-going; teacher feedback involves teacher intervention in the drafting process, the revision process, and the presentation of product. Secondly, in the writing conferences, the teacher provides students an opportunity to talk about writing, assistance and advice on the content/meaning of the written text, helping them expand and clarify thinking about audience(reader) and purpose.
