Consumers attribute human personality to products or stores as well as brands. As brand personality is imprinted to a consumer's mind, in e-commerce, the concept of store personality needs to be examined by comprehending the e-brand personality. Unlike the recent studies that focus primarily on the portal site, we attempt to identify e-brand personality of online shopping malls that sell fashion products. This study also examined the impact of the parent company's attributes on e-brand personality. A survey was conducted to 240 females and 240 males in their 20s or 30s. E-brand personality of three different types of the Internet shopping mall was evaluated by 160 respondents, respectively. As a result, we found that Internet shoppers perceive that e-brands have four distinct personality dimensions: young, reliable, sophisticated, and creative. Among the four dimensions, "young" and "reliable" showed the most significant influence on intention to visit the shopping mall site. Besides, e-brand personality varied with parent companies' attributes such as reputation, credibility, and fashion industry-relatedness. Especially, credibility of the parent company showed a strong positive relationship with e-brand personality.

The purpose of this paper is to develop an evaluation model for e-government system in Korea which is one of world best practices of e-government systems. We have presented a method to perform an efficiency analysis of each e-government service which in a component of e-government system in Korea and to establish a benchmark target for each e-government service. To do this, the output-oriented DEA(Data Envelopment Analysis) CCR model was performed for the selected 12 e-government public services of Korean e-government system in this paper. As a result of DEA analysis, first the internet civil appeal support service, the employment comprehensive information service, and the company support information service were evaluated as the efficient solutions among the 12 e-government public services. Second the remaining 9 e-government public services were evaluated as the inefficient information services which should be improved in terms of their service levels. Finally the benchmark targets for the inefficient e-government services were suggested to improve those inefficient systems through DEA analysis.

Japanese encephalitis virus (JEV) envelope (E) protein holds great promise for use in the development of a recombinant vaccine. Purified recombinant E (rE) protein may be useful for numerous clinical applications; however, there are limitations in using the Escherichia coli expression system for producing high-quality rE protein. Therefore, in this study, the yeast expression system was used to generate the rE protein. For protein production using the yeast system, the full-length JEV E gene was cloned into Pichia pastoris. SDS-PAGE and immunoblotting analysis demonstrated that the rE protein had a molecular mass of 58 kDa and was glycosylated. The predicted size of the mature unmodified E protein is 53 kDa, suggesting that post-translational modifications resulted in the higher molecular mass. The rE protein was purified to greater than 95% purity using combined ammonium sulfate precipitation and a SP-Sepharose Fast Flow column. This purified rE protein was evaluated for immunogenicity and protective efficacy in mice. The survival rates of mice immunized with the rE protein were significantly increased over that of Hyphantria cunea nuclear polyhedrosis virus E protein (HcE). Our results indicate that the rE protein expressed in the P. pastoris expression system holds great promise for use in the development of a subunit vaccine against JEV.

본 논문에서는 OTP (One-Time Programmable) IP (Intellectual Property)의 개발비용을 절감하고 개발 기간을 단축하기 위해 로직 트랜지스터만 이용한 로직 eFuse (electrical Fuse) OTP IP를 설계하였다. 웨이퍼 테스트 시 테스트 장비에서 FSOURCE 패드를 통해 VDD (=1.5V)보다 높은 2.4V의 외부 프로그램 전압을 eFuse OTP IP에만 공급하므로 eFuse OTP 이외의 다른 IP에는 소자의 신뢰성에 영향을 미치지 않으면서 eFuse OTP cell의 eFuse 링크에 높은 전압을 인가하도록 하였다. 한편 본 논문에서는 128행 ${\times}$ 8열의 2D (Dimensional) 메모리 어레이에 직접 FSOURCE 전압을 인가하여 eFuse에 인가되는 프로그램 파워를 증가시키면서 디코딩 로직 회로를 저면적으로 구현한 eFuse OTP 셀을 제안하였다. 동부하이텍 $0.11{\mu}m$ CIS 공정을 이용하여 설계된 1Kb eFuse OTP 메모리 IP의 레이아웃 면적은 $295.595{\mu}m{\times}455.873{\mu}m$ ($=0.134mm^2$)이다.

Considering rapid development of Internet Portal Site Contents in Korea, it is an important issue to analyze consumers' satisfaction and e-loyalty. This research develops, and empirically test a model for explaining/predicting the satisfaction and e-loyalty with internet-based Electronic Trade Site. This paper describes a theoretical model for investigating the Satisfaction and e-Loyalty of the Electronic Trade Site. This study investigates the concept of the satisfaction, e-loyalty in Electronic Trade Site and its determinants, and tries to establish e-loyalty analyzing model. The model of the satisfaction, e-loyalty electronic trade site is tested here using data from 158 samples. Based on the research model, a comprehensive set of hypotheses is formulated and a methodology for testing them is outlined. some of the hypotheses are tested empirically to demonstrate the applicability of the theoretical model. In examining the relationships of the determinants factors, service quality satisfaction show in significantly by Reliability, Information Provided, Trustworthiness, Convenience, International of contents but that show in not significantly by Interaction. In addition, Electronic Trade site retention shows indirect effect between customer satisfaction and referral. Although our research can not show the determinants of e-loyalty in the electronic trade site the empirical result give both theoretical and managerial implication for managing the consumers' satisfaction and e-loyalty in electronic trade site.

In this paper, a study was conducted on the power amplifier control required to design an eLoran transmitter system using a low-height antenna. The eLoran transmitter developed during the eLoran technology development project conducted in Korea used a small 35 m antenna due to the difficulty of securing a site for antenna installation. This antenna height is very low compared to the height of 750 m which is required for eLoran 100 kHz signal transmission without any radiation loss. In the case of using such a small antenna, not only the radiation efficiency of the transmission is lowered, but also the power module control must be performed more precisely in order to transmit the eLoran standard signal. The equivalent RLC circuit of the transmitter system was implemented and transient analysis was conducted to derive the input required voltage for satisfying the output requirement. The voltage waveform was also generated by the RLC circuit analysis to generate the eLoran signal. Furthermore, we suggest power width modulation method to control eLoran power amplifier module more sophisticatedly.

This study developed e-book content in order to use e-books as a tool to provide more efficient classes to learners who are familiar with smart devices and online spaces. E-book contents were produced using Sigil-0.9.10. The development process is as follows. Before e-book development, it is necessary to prepare manuscript files, image files to be inserted, fonts to be used, and e-book covers. After inserting the book cover images, it is necessary to register the table of contents using the title tag and register the free fonts. Also, a style must be created for text or images used in the main text connected to a file containing the entire text. Then, after separating the entire text file into separate files according to each chapter, the text is completed in turn. E-books were produced focusing on hyperlink functions so that educational content and various example images could be accessed. Currently, there is a lack of research on e-books as textbooks in universities within the fashion design major. In the future, if e-book contents are developed according to the characteristics of courses and the level of learners, they can be used as effective teaching tools.

Information technology and the Internet have had a dramatic effect on education method and individual life. Universities and companies we making large investments in e-Learning applications but are hard to pressed to evaluate the success of their e-Learning systems. e-Learning can be seen as not only one of Internet based information systems which can provide education services but also one of teaching-teaming methods which can implement self-directed teaming. This paper tests the updated model of information system success proposed by Delone and McLean using a field study of a e-Learning. The five dimensions - information quality, system quality, service quality, user satisfaction, net benefit - of the updated model are parsimonious framework for organizing the e-learning success metrics identified in the literature. Questionaires are collected from 107 students who are enrolling a e-learning class using online survey. The model is tested using SPSS and LISREL. The results show that information quality and service quality are significant predictors of user satisfaction with the e-Learning system but system quality is not. Also user satisfaction is found to be a strong predictor of the learning performance. This strong association between user satisfaction and teaming performance suggests that user satisfaction may serve as a valid surrogate for teaming performance. Empirical testing of the updated DeLone & McLean model should therefore be extended to cover a wider variety of systems.
