ICC(International Chamber of Commerce) developed new rule on the presentation of electronic record in L/C transactions. This rule named as the e-UCP. The gists of this article are on the application of e-UCP in practice and it's some problems. The e-UCP is the supplement of current exisiting UCP but is superior to UCP under some circumstances. The e-UCP is only apply to the presentation of electronic record regardless of type of L/C(for example, traditional paper L/C or electronic L/C). The presentation of electronic record has some problems which has not seen in the presentation of paper document. These peblems are Time, Place of presentation, and format of electronic record and so on. The e-UCP provided on the basis of these problems. However, the e-UCP has some obscure provisions on the examination of electronic record and the corruption of electronic record. Who is responsible for the corruption of electronic record by the virus on the system of bank ? The current e-UCP is not clear on this matter. We have to note followings in case of presenting the documents electronically and applying the e-UCP. First, Beneficiary has additional duty to notice of completion of presentation. Second, It will be increasing the clean NEGO through prompt feedback of the descrepancy at the presenting time. Third, It is no use of L/G(Letter of Guarantee).

e-Science is for increasing the research productivity in epochal way using research resources like high performance computers, large capacity data storage, experimental instrument and researchers. For the research activities without being limited by time and space, the collaboration system is prerequisite condition. This paper shows the comparisons and analysis of features of popular collaboration systems in the point of e-Science. We considered that the number of supporting video streams, scalability and cost are main issues for the e-Science collaboration system. By these, we conclude that Access-Grid(AG) is best suitable for the e-Science collaborative research system. This paper shows the current AG status and the future way of AG.

This paper examined a e-Business utility of on-line shopping mall firms. Based on the literature review and cases study, the following results were found. First, in e-business policy, it was found that partnership between government and market are very important to e-business utility. Second, e-CRM of on-line shopping mall firms should be considered web site design based on commodity, cafe based on experience and information shares, and transaction confirm service. Third, B2C e-commerce model should be contained firm-specific force, customer oriented force, social force, and technology force.

Charged micro-particles are widely used as the key components for many electrical applications such as an e-paper, a touch panel, a printer toner and an electronic ink. Among them, the e-paper is an emerging reflective type display using the charged particles that has the advantages of the extremely low power consumption and sunlight readability. To create images on the e-paper, we confine black positively-charged and white negatively-charged particles between bottom and top electrodes and selectively apply the electric field. When the Coulomb force by an applied electric field is greater than the adhesion force between the charged particle and the electrode, the particles' transition happens resulting in the change of color between black and white. Therefore, the adhesion force is a very important factor for designing and estimating e-paper's operation. In this study, we constructed a basic model for particle's transition and an adhesion force equation describing particle's transition with three different forces: electrostatic image force, Van der Waals force and gravitational force. The simulation results showed that the gravitational force is negligible for the interesting range for the charge and the radius, and the adhesion force can be strongly dependent on the particle's charge and radius.

This paper was conducted to verify the relationship of understanding of learning, service quality, efficiency of convergence e-business valuation. For this paper, it surveyed 179 students and the data were collected Nov. 2~30, 2015. This research analyzed all the samples through ANOVA, t-test utilized by SPSS 22.0 The results as follow. First, understanding of learning, service quality, efficiency had statistically significant difference according to gender. Second, understanding of learning, service quality, efficiency showed statistically significant difference according to grade. The results of this study reveal the fact that the general characteristics like gender and grade made difference to the understanding of learning, service quality, efficiency. Furthermore, this paper may need to include various variables of understanding of learning, service quality, efficiency and suggest research about several university.

In this paper, we proposed E-plane structures to obtain the high insertion loss at stopband and show that T-equivalent and K-inverter of Triple E-plane structures are better than those of All-Metal Insert E-plane structures. To show the characteristics first order bandpass filter are designed and tested at X band.

Enzymatic hydrolysis of waste office paper was evaluated using three commercial cellulases, Acremonium cellulase, Meicelase, and Cellulosin T2. Varying the enzyme loading from 1 to 10% (w/w) conversion of waste office paper to reducing sugar was investigated. The conversion increased with the increase in the enzyme loading: in the case of enzyme loading of 10% (w/w), Acremonium cellulase yielded 79%conversion of waste office paper, which was 17% higher compared to Meicelase, 13% higher than that of Cellulosin T2. Empirical model for the conversion (%) of waste office paper to re-ducing sugar (x) was derived from experimental results as follow, x = $kE^{m}t^{(aE+b)}$ where k, m, a, and b de-note empirical constants. E indicates initial enzyme concentration.

With the advent of new customs and practice of electronic records, the eUCP provides some useful guidance to accommodate the presentation of the paper documents electronically and also provides necessary rules to allow the UCP and eUCP to work together. There is no denying the fact that many of the UCP articles are not impacted by the presentation of electronic equivalent of paper documents, so the integrated application of the UCP and eUCP will be broad enough to allow for developing practice in this area. This study discusses some theoretical implication for efficient utilization of the global usages of letter of credit through the finding of optimal solution in the state of uncertainty caused by the electronic presentation of documents. This study suggest that the decision rules be developed to show how individuals choose optimal portfolio between the eUCP and the UCP that maximize their expected utility in letter of credit transaction, and also suggest that the optimal portfolio be determined at the point of tangency between the efficient trading line and the highest indifference curve in the mean-variance plane. This study finally recommends three rebuttable doctrines with regard to the relationship between the eUCP and UCP such as linkage characteristics, generation lap propensity, and homothetic application rule, which may be the critical standards for understanding of the integrated usages of the eUCP and UCP.

The purpose of this paper is to derive the categories of negative e-WOM (electronic word of mouth) via consumer review. Disclosing the details of negative e-WOM based consumer reviews has never been done before. For this reason, a content analysis was adopted to provide knowledge and understanding of the phenomenon. This paper analyzes the content of 630 consumer reviews posted on the open market internet site, www.auction.co.kr. The analysis was conducted from October 20th, 2008 to March 10th, 2009. The results indicated that the negative e-WOM based consumer reviews can be divided into two categories: the cognitive evaluation and the expression of consumer's emotion. The category of cognitive evaluation is consisted of negative e-WOM of product, negative e-WOM of service, and warning about the risk of purchasing products. The category of expressing consumers' emotion are composed of venting customers' dissatisfaction and passive response of dissatisfaction. Investigating the details of negative e-WOM has a number of implications. Most importantly, the results revealed multidimensional structure of negative e-WOM. This understanding of negative e-WOM communication allows marketers to improve products and services that better meet customers' current and future needs.
