In this paper, I examined the trends of standardization and electronization of trade documents and SWIFT network. Also, I reviewed on emerging electronic documentary credit for electronic payment and electronic presentation of documents. New international trade customs and practices are being established and changed as a result of the growth of the Internet and other on-line networks. At the same time there is increasing pressure to move from existing paper-based documentary credit to electronic documentary credit. Several projects devoted to development of an electronic letter of credit infrastructure have recently been proposed such as Bolero, SWIFTNet, UNeDocs and eUCP, etc. Yet, little can be done until the presentation process is electrified between traders and banks. Also, interbank communication of letters of credit has long been electronic, mainly through the SWIFT. However, it is not functioned between applicant and beneficiary, although the solution of SWIFTNet has recently been developed. The Banking Commission of International Chamber of Commerce established a working group consisting of experts in the related fields to prepare the appropriate rules as a Supplement to UCP 500 for Electronic Presentation: eUCP. The eUCP will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. Some problems of electronic presentation under the eUCP, exist such as format, presentation of electronic records and the way of beneficiary's notice for completeness under the Article e5 if more than one record is to be presented electronically by third parties. Therefore, it is encouraged to provide more detailed guide for eUCP Article e5.

Background: Immunomodulators enhancing MHC-restricted antigen presentation would affect many cellular immune reactions mediated by T cells or T cell products. However, modulation of MHC-restricted antigen presentation has received little attention as a target for therapeutic immunoregulation. Here, we report that lectins isolated from mushroom Fomitella fraxinea enhance MHC-restricted exogenous antigen presentation in professional antigen presenting cells (APCs). Methods: Lectins, termed FFrL, were isolated from the carpophores of Fomitella fraxinea, and its effects on the class I and class II MHC-restricted presentation of exogenous ovalbumin (OVA) were examined in mouse dendritic cells (DCs) and mouse peritoneal macrophages. The effects of FFrL on the expression of total MHC molecules and the phagocytic activity were also examined in mouse DCs. Results: DCs cultured in the presence of FFrL overnight exhibited enhanced capacity in presenting exogenous OVA in association with class I and class II MHC molecules. FFrL increased slightly the total expression levels of both class I (H-$2K^b$) and class II (I-$A^b$) MHC molecules and the phagocytic activity of DCs. Antigen presentation-enhancing activity of FFrL was also observed in macrophages isolated from mouse peritoneum. Conclusion: Lectins isolated from the carpophores of Fomitella fraxinea increase MHC-restricted exogenous antigen presentation by enhancing intracellular processing events of phagocytosed antigens.

The present study was to investigate the mediating and moderating effects of self-acceptance on the relationship between perfectionistic self-presentation and peer relationship quality in adolescents. Two hundred and sixty-one middle school students were surveyed. The results were as follows. First, self-acceptance had a full mediation effect on the relationship between perfectionistic self-presentation and peer relationship quality. That is, peer relationship quality was only indirectly affected by perfectionistic self-presentation through self-acceptance. Second, self-acceptance had a significant moderating effect in the relationship between perfectionistic self-presentation and peer relationship quality. Perfectionistic self-presentation did not have a statistically significant impact on peer relationship quality in the group with low self-acceptance, but it did in the group with high self-acceptance. Therefore, this study suggests the need for counseling and educational approaches to improve adolescents self-acceptance by verifying the effect of self-acceptance in perfectionistic self-presentation and peer relationships.

For the pure braid groups, this paper gives a positive finite presentation whose generators are the standard Artin generators, and determines whether the submonoid generated by the Artin generators is a Garside monoid or not.

The braid group $B_n$ maps homomorphically into the Temperley-Lieb algebra $TL_n$. It was shown by Zinno that the homomorphic images of simple elements arising from the dual presentation of the braid group $B_n$ form a basis for the vector space underlying the Temperley-Lieb algebra $TL_n$. In this paper, we establish that there is a dual presentation of Temperley-Lieb algebras that corresponds to the dual presentation of braid groups, and then give a simple geometric proof for Zinno's theorem, using the interpretation of simple elements as non-crossing partitions.

This paper describes the design and implementation of multimedia presentation system based on the compensative synchronization algorithm. We proposed the compensative synchronization algorithm in compensation for previously preestimated delay-time in order to minimize delay-time in multimedia presentation system. The presentation system uses compensative synchronization algorithm and have multimedia objects as text, raster graphics, geometric graphics, or audio.

In the area of speech processing, raw signals used to be presented into 2D format. However, such kind of presentation methods have limitation to extract characteristics from the signal because of the presentation method. Generally, not much information can be detected from the 2D signal. Strange attractor in the field of chaos theory provides a 3D presentation method. In the area of recognition problem, signal presentation method is very important because good features can be detected from a good presentation. This paper discusses a new feature extraction method that extracts features from a cycle of the strange attractor. A neural network is used to check whether the method extracts suitable features or not. The result shows very good points that can be applied to some areas of signal processing.

The paper describes the design and implementation of Auto-Presentation Feature, Hanuri/C, as Client/Server tool. Hanuri/C provides editing functions for the sequence, period, type, and repeating number of auto-presentation. With the pre-fixed sequences users can get automated presentations through Hanuri/C. The proposed auto-presentation function provides an ability to automatically present the data in the database system without user intervention.

This study examines the effects of self-presentation and aesthetics on purchase intentions toward a brand-new smartphone through a research model that accounts for these intentions in a more comprehensive manner than traditional ICT frameworks. The constructs were selected based on the three-level processing theory: aesthetics at the visceral level, perceived usefulness and playfulness at the behavioural level, and self-presentation at the reflective level. The hypotheses were developed from self-presentation theory and the attractiveness stereotype which is one of theories in human-computer interactions (HCI). For the validation of hypotheses, the research model was empirically tested for the purchase intention of Apple's iPhone5 by university students in Korea.

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.
