The origin of Korean mime is traceable to sacred actions of prehistoric age. There are materials about mime of this age in the archeological materials of this age, oral literature/myth, and written literature about this age. There were traces of the most original form of mime in primitive ritual of tribal nation age. The mimes of Samkooksidae/Tree Nation Age of Korea were presented to forms of Kamoobekhee(歌舞百戱)/Sanakbekhee(散樂百戱). We can discover traces of mime of this age in Hosunmoo(胡旋舞), Gwangsumoo(廣袖舞), Kweraehee(傀儡戱), Keeak(伎樂), Kummoo(劍舞) Muaemoo(無㝵舞), and so forth. Especially, Keeak in Beckjae was mask mime of Buddhistic contents. We can recognize that secular theatres were more diversified and strengthened than sacred thaetres in Nambukgooksidae/South-north Nation Age. According to these changes, there were many changes in the mime of this age. We can concretely find traditions of mime of this age in Cheryongkamoo(處容歌舞), Hwangchanmoo(黃倡舞), Taemyun(大面), Wuljen(月顚), Sodok(束毒)', Sanyae (狻猊), and so forth. Mimes of Koreasidae/Korea Age take diverse forms of puppet play, mask play, dance play. Established traditional mimes as Cheryongkamoo(處容歌舞) were widely disseminated in society. And dance plays of mime form as Hunsundo(獻仙桃), Pokurak(抛毬樂), Yunhwadae(蓮花臺)' were imported from Song Nation of China. Mime of Chosundidae/Chosun Age were developed with changes of theatre that were divided into Kyusickjeehee[規式之戲] as Kwangdae(廣大), Ser-in(西人), Joojil(注叱), Rongryung(弄鈴), Kendoo(斤頭) and Sohakjihee[笑謔之戱] as Soochuk(水尺) Sengkwangdae(僧廣大). Styles of theatre in this age were specialized into mudangkuk, Pungmoolkut, Inhyunguk/Puppet play, Talnoree/Mask paly, Pansori, Kungjoong Kamuakguk. According to this changes, mime of this age were specialized into diverse aspects. Korean mime were specialized into Kutnorum-formed mime, Inhyungnorum-formed mime, Jabsaeknorum-formed mime, Talnorum-formed mime, Kungjoongmuyong-formed mime, Pansori-formed mime, and so forth.

This article is considered how to utilize mime in the mudang gut. Actually, mime can't be the crux of mudang gut, and the only factors of mime is utilized. Therefore, the purpose of this article is to draw another nets of meanings in Mudang gut, not to study mime. First of all, I surveyed the constituent factors of mudang gut. One gutpan is combined with various factors. As a shamans(mudang), a musician, a jang gu player, a gongyangju(taking charge of food), a sibongja(helper for a shaman), and madangsoe (an under servant), they played their roles. The gut consists of equipment, food, clothes, music and dance. Next, I derived two nets of meaning out of considering a mudang gut performance of mudang (shaman). First, god in a general gutgeori appears expressing their existence by using mime with the music. Second, the following god appears expressing themselves using only mime without music. After showing who he is through action and facial expression, he continues to play a gut. Accordingly, mime of seoul gutpan plays a role to reveal the existence of god. Also, I divided the way of performing mudang gut into language performance and motions and then suggested that mime was mainly used in the motions. I surveyed a gutgeori using mime in the concrete. Through this, I suggested that the shaman used mime, when sending a deadman to the next world in a Jinogi gut. I suggested that mime was utilized repeatedly at the process of repelling the misfortune in a jaesu gut.

RFC3261에 정의된 SIP 프로토콜에는 보안 및 인증과정을 위한 동작 메커니즘을 정의하고 있다. 서비스 제공을 위한 인증이나 권한 점검을 위해서는 HTTP Digest방식이 가장 일반적이고 검증된 방식이긴 하나, 보안의 측면을 보았을 때 안전하지는 않으며, 서버와 단말 또는 단말간의 인증에만 사용되므로 완벽한 형태의 보안을 제공한다고 볼 수 없다. 이러한 보안상의 무결성, 안정성에 있어서의 기능을 충족시키기 위해 RFC3261의 후반부에서는 TLS와 S/MIME의 지원을 권장하고 있으며 현재 IETF에서 진행중인 draft나 각종 RFC에서도 보안 문제를 해결하기 위해 S/MIME과 TLS를 필요한 사항으로 정의하고 있다. 본 고에서는 S/MIME기능을 SIP프로토콜에 적용하기 위해 필요한 사항 등을 구현관점에서 바라볼 것이며, 이를 위해 해당 기능의 구현을 위해 사용된 구현구조 및 관련 API의 설명을 통해 접근하고자 한다.

In this paper, an analysis problem of repair levels and spare part allocation for MIME(Multi indenture multi echelon) systems is studied using simulation and meta-heuristics. We suggest a method to determine simultaneously repair levels and spare parts allocation to minimize the life cycle cost of MIME system under availability constraint. A simulated annealing method is used to analyze the repair levels and genetic algorithm is used to obtain the optimal allocation of spare parts. We also develop a simulation system to calculate the life cycle cost and system availability. Some numerical examples are also studied.

In E-mail based accounting system, the remitter does not have need to find collector's account number. To transfer money to a collector's account, what remitter need is just a collector's E-mail address. But the current E-mail based accounting systems are built on SSL technology. Basically SSL provides some security services - confidentiality, user authentication and data integrity, but does not provide non-repudiation. So, in the current E-mail based accounting system, it is possible to deny transaction. And there is no receipt of transaction. In this paper, we design and implementation of a S/MIME applied Secure Payment Mechanism. In our system, every account information - account number, receiver name, amount of money, etc. - is included in a 'check' message. And this message is protected under the Secure Web-mail using S/MIME. In a view point of the convenience, users using our system do not have need to find collector's account number. And in a view point of the security, our system provides confidentiality, user authentication, data integrity and non-repudiation. Moreover our system provides a receipt.

This paper is a historical study on mime or pantomime in the chinese theater. What is the origin of chinese mime? This is a very difficult question to answer. But I thought its early model can be found in actions of ancient actors who are believed to precede any genre of theater and actually I could found a very significant proof in historical records which have been ignored generally. It is an episode of Youmeng(優孟) in Chu(楚) dynasty. According to this episode, the history of chinese mime has lasted at least over 2600 years. In my opinion, chinese mime had been organized in ritual genre in early theater and its development had been mostly based on the jiaosehangdang-system(脚色行當制). Most chengshi-movements(程式動作) of zuo(做) and da(打) have been organized in recent several centuries. But a further study on them shows us that the real origin of them is the ancient dance wu(舞). Afterwards the wu(舞) separated into two types of dance the so-called wenwu(文舞) and wuwu(武舞). So we can say that wenwu(文舞) and wuwu(武舞) had a direct influence on most chengshi-movements(程式動作) of zuo(做) and da(打).

This paper started with my effort to find connections between Empty Hands, which was put on the stage at the Mime House in Chuncheon, Gangwon Province, and Jindo Ssitgimgut. The mimist Yu Jin-gyu(58) adopted so many elements from Jindo Ssitgimgut for his performance that I felt that it was the pantomime version of Jindo Ssitgimgut. Of course, the pantomime took the form of gut based on shamanism in terms of story. Watching the pantomime, I once again saw the possibility of developing Korea's cultural archetypes into cultural contents. Helen Lannaghan, the art director of London International Mime Festival of 2005, saw his performance at the conference of Chuncheon International Mime Festival and invited it to the London International Mime Festival praising that it's full of Korean elements, minimalist, and modern at the same time. In fact, Empty Hands, which boasts great harmony among the Korean objet, Oriental thoughts, Samulnori, and Western contemporary mime, was invited to many foreign festivals including the Mimos International Mime Festival in 2000, Polish International Mime Festival in 2001, Mongol's International Mime Festival in 2002, and Belgium's International Mime Festival in 2003. In addition, it's recognized for its artistic values and had a chance to shine in another international setting at the London International Mime Festival whose reputations have been worldwide. All those achievements are the result of Yu's constant effort to reflect Korean elements through his movements. What I saw in his pantomime was the possibility that plays based on Korea's cultural archetypes such as Jindo Ssitgimgut could play an important role as a global content of performance culture. Pursuing the possibility further, I analyzed the factors that brought the worldwide recognition to Empty Hands and searched for the ways to create solid storytelling with Jindo Ssitgimgut and make a huge hit on the international stage. It should be noted once more that the pantomime Empty Hands launched Korea's unique performance culture to the world stage by making great use of the traditional Korean cultural contents.

Spare part problem of MIME (Multi Indenture Multi Echelon) system under availability constraint has been studied for several decades. In most of existing studies, it was very difficult to obtain the optimal numbers of spare parts and some approximate methods were proposed under many restrictions. In this paper, we consider a simulation to estimate the total cost rate and system availability and a genetic algorithm to obtain the optimal numbers of spare parts. Some numerical examples are also studied.

현존하는 국내외 인터넷 경매시스템은 경매하고자하는 상품을 게시하고 그 상품에 대해 경매 입찰자들이 입찰(bid)을 제시함으로 해서 최종적으로 경매 시간 내에 가장 높은 입찰가를 제시하는 경매 입찰자에게 거래가 낙찰되는 형식이 사용되고 있다. 하지만 인터페이스 부분에 있어서 사용자의 편의성을 고려하지 않을 뿐만 아니라 경매 참여자에게 지속적인 입찰제시와 확인 등의 여러 가지의 사용자 행위를 요구하므로 전자상거래의 고객 편의를 위한 One-step processing을 만족시키지 못하고 있으며 사용자의 행위를 대신하여주는 에이전트를 이용한 자동 처리 부분은 거의 고려하지 않은 시스템이므로 사용자의 편의성 면에서 단점을 가지고 있다. 따라서 본 논문에서는 자동적으로 사용자를 위해 입찰 행위를 대신하여 주는 사용자 입찰 가격 전략 알고리즘을 제안하여 기존에 사용되었던 일반적인 경매 시스템의 단점을 보완하여 효율적인 입찰 가격 정책을 이용하며 또한, 모든 일련의 경매에 대한 사용자 행위를 MIME(Multipurpose Internet Mail Extensions) 프로토콜을 이용한 메일 양식에 응답만으로 모든 경매 서비스를 받을 수 있는 인터넷 경매 시\ulcorner템을 설계 및 구현하고자 한다.

인터넷 ED 시스템은 TCP/IP 프로토콜을 사용하여 문서를 전송하게 되는데 전송 도중 패킷 스니핑에 의하여 문서정보가 노출될 수 있다. 이러한 정보노출을 방지 할 수 있는 대표적인 보안 기법에는 인터넷 EDI 보안 프로토콜로 권고되고 있는 S/MIME과 전자우편 암호화 프로그램인 PGP가 있다. S/MIME은 내부에서 사용되는 암호알고리즘의 사용제약으로 인하여 완벽한 구현이 어려우며 PGP의 경우 보안측면에 있어서 수신부인 방지 기능을 제공하지 못하고 있다. 본 논문에서는 S/MIME과 PGP에서 사용되고 있는 보안 기법을 분석하여 기밀성, 인증, 무결성, 송수신 부인방지 기능을 가지는 시스템을 제시한다. 본 시스템은 기존 암호화 알고리즘들의 문제점을 보완할 수 있는 혼합모델을 사용하여 기밀성과 무결성, 송신부인방지 기능을 구현하였고, 인증서버인 삼성 PKI 서버와의 인터페이스를 개발하여 인증을 획득하였다. 수신부인방지의 경우 암호화 메카니즘만으로 획득될 수 없기 때문에 수신자가 문서를 읽는 순간 송신자 측으로 수신자의 전자서명을 자동으로 전송해 주는 프로토콜을 통하여 구현하였다.
