인터넷의 빠른 성장으로 인해 E-mail은 특정 부류만의 사람이 사용하는 것이 아니라 일반 대중에게도 널리 사용되는 생활의 일부분이 되었다. 현재의 POP3 구조에서느 원격 접속을 시도할 경우 사용자의 ID와 Password는 암호화가 안된 상태로 전송된다. 이러한 것 때문에 여러 보안 공격의 대상이 될 수 있으며 여러 보안 문제를 발생시키고 있다.본 논문에서는 기존의 POP3에서 PASS라는 명령어를 통한 사용자 인증 과정에서 나타나는 무제점을 지적하고 이를 방지하기 위한 새로운 인증방법을 One-Time Password System을 이용해서 제시하고 구현하고자 한다. 또한 One-Time Password System을 이용해 불법적인 방법으로 알아낸 암호의 재사용을 방지했다. 또한 암호화 통신을 위해 관용 암호화 방식의 IDEA 알고리즘을 이용했으며, 키 분배와 관리 문제는 One-Time Password System에서 생성한 키를 IDEA의 비밀키로 사용함으로써 해결했다.

Even though the initial mass function (IMF) of the first generation of stars played important roles in reionization of the universe, subsequent star formation, and chemical enrichment of the universe, it is still very uncertain. In this study, among the several indirect ways of estimating the IMF of the population III (Pop III) stars, we make use of extremely metal-poor (EMP; [Fe/H] < -3.0) stars in the Milky Way, in order to infer the characteristic mass range of Pop III stars. As the progenitors of many of the EMP stars are known to be Pop III stars, we attempt to construct the characteristic mass range of the progenitors (e.g., Pop III stars) of the EMP stares by comparing their observed abundance pattern of various chemical elements with chemical yields from supernova models.

Hallyu pop-culture contents which has influenced the world has sufficient preservation value as a cultural asset. However, there is still a lack of awareness of long-term preservation of Hallyu pop-culture contents and digital archiving is not in full swing, too. We requires accurate understanding of the concept, characteristics, format, media, and relationship of contents for digital archiving of Hallyu pop-culture content. Thus, this study analyzed and organized the concept, characteristics, and preservation subject of Hallyu pop-culture contents, as basic study for digital archiving of Hallyu pop-culture contents. In addition, we investigated the current status of digital archives (systems/institutions) of Hallyu pop-culture contents and Hallyu pop-culture contents, and presented basic proposal based on the problem factors.

The purpose of this study is to increase the development possibility of K-pop music by analyzing K-pop music and analyzing the use of world music in it. As a research method, we will first look at the world music elements Puerto Rico's reggaeton, Jamaica's toasting, and the melody of Indian music. After that, we analyze two songs, Hyo-yeon's and Hyun-A & Dawn's , with rhythm and melody elements to find out the utilization of World Music. As a result of the study, it was found that it rhythmically showed the type of Dembow rhythm derived from Puerto Rico's reggaeton, and melody followed the form of Jamaican toasting and the melody of Arabic music. This study is meaningful in presenting the possibility of development and various directions of K-pop in the future by analyzing the use of world music used in K-pop music. Through the convergence of various world music and K-pop, I hope that K-pop music will become a culture that is supported by a wider public.

In existing internet, e-mail protocols including POP3 and IMAP4, provide e-mail services fir exchanging messages with texts, hypertext and images as well. For the e-mail services in wireless mobile network, mobile e-mail service providers have to install a mobile exclusive e-mail server or have to convert e-mail to mobile exclusive e-mail with wireless application format in case of POP3 protocol. In the e-mail service of IMAP4 case known as web-mail, it is difficult to view e-mail directly from server without IMAP4 mobile client because e-mail is stored in mail server side with remote file server. In either case, it also has the problems of viewing the e-mail of hypertext and image information at mobile. This paper provides e-mail extraction engine with image and hypertext conversion facilities that can be applied in wireless mobile internet and it is optimized in mobile communication environments such as a small display, small size of memory with web-mail protocol based on IMAP4 as well as POP3 mail protocol.

The purpose of this study was to observe a case study of pop-up stores in an apparel company in Korea in order to evaluate different feel and to determine the purchase behavior of pop-up visitors of three major fashion brands. This research was conducted through secondary data collection and primary data collection. A survey was conducted among NIKE, KUHO, and PUMA pop-up store visitors who were 20 to 40 years old, via questionnaires. Data were collected on-line and off line at the pop-up store. Data were analyzed using SPSS program. Through data analysis, we learned that most of the study participants were captivated by the digital elements in the environment of the NIKE pop-up store. Puma, the second most favorably ranked, was favored for its interior design. Meanwhile, KUHO stimulated its customers with its limited edition fashion products at a good price. Several feels of visitors about the pop-up stores were significantly different among the 3 different brands. There was a significant difference in purchase criteria, such as brand recognition, size, and design among visitors of the three different brands. Visitors who preferred KUHO considered design of products more than NIKE-preferred visitors. In conclusion, the clothing pop-up stores have the possibility of satisfying consumers' desires. Each brand can achieve a good performance in promotion with a differentiated strategy.

This article aimed at semiotically analyzing and encoding the characteristics of Pop. Artistic style of a dress in the 2000's, and understanding social and cultural meaning to characteristics revealed at modern style of a dress. As research methods, Pop. Art factors were adjusted to non-individuality, openness, eroticism, parody through precedent research comparing and considering Pop. art, and 61 photos were selected, and they were analyzed into signifier and signified. It's analysis results are as follows. Non-individualistic image revealed modern style of a dress was intensively indicated at the pattern aspect of Pop. Art style of a dress, and any remarkable characteristics were not shown at the form aspect. Non-individuality was actively and progressively expressed due to the effect of the 2000's trends to pursue of frank desire, artistic and sensual life. For open image revealed at modern style of a dress, the characteristics were intensively highlighted at the details and accessories of style of a dress, and at the details and accessories of style of a dress, and at textile and pattern aspect, and notable signifier did not turn up. Pop. Artistic eroticism in the 2000's could be seen to unconditionally expose, or commercialize sex, but fashionably and gorgeously re-interpret it, which was found that the expression to women was changed in a free and emotionally-oriented way by the influence of feminism, expansion of feministic thought and optimism on New-millenium. At parody, simple and humorous parody rather than deep intended or heavy mattered one was seen, which means the effect of the 21st culture pursuing pleasure, fun and humor appeared as an positive parody phenomenon. It is found that the Pop. Art style of a dress in the 2000s shows up as a feministic, bright, cheerful Pop. Art in that it creates exaggerated harmony mixed with decorativeness ad functionalism, and pursue for frank desire and reflects optimistic trend of New Millenium seeking for fun and humor.

SPC(Statistical Process Control) provides objective means of controlling quality in any transformation processes by analyzing statistically data gathered in the process. Considering the fact that a measure to feedback results of the process investigation in the real time is required, it is very practical to construct the SPC system as a module of the POP(Point of Production) system. Because this approach can make the investment cost reduced and achieve goals of production/process control and SPC simultaneously. This paper designed and developed the SPC system of firm S that manufactures automobile parts
