현재 네트워크 사용자 특히 인터넷 사용자 증가 속도는 가히 기하급수적이라 할 수 있다. 더불어 질 높은 서비스에 대한 요구가 제기되고 있는데 이것은 필연적으로 트래픽의 폭증을 가져오고 있다. 따라서 네트워크 트래픽의 효율적 분석 관리는 과거에 비해 더욱 중요한 사항으로 대두되고 있다. SES를 이용한 네트워크 분석은 네트워크 관리자들에게 쉽고, 효율적으로 트래픽데이터를 접근이 가능하다. 따라서 본 연구의 목적은 대용량의 네트워크 트래픽 데이터 효과적으로 처리하기 위해 최적화된 네트워크 트래픽 시스템을 구현하기 위하여 데이터 엔지니어링 방법론인 SES를 이용하여 네트워크 패킷의 정보 구조를 설계한후 DEVS를 이용하여 분석하는 시스템을 구현하고자 한다.

The digital informational era of the 21st century requires the fostering of human resource in the field of software with creativity and personality. This paper deals with the educating method in programming course for non-majors which fosters creativity for problem solving ability and personality using cooperative interaction to build communication ability. We also seek to build a model through DEVS methodology for creative problem solving and analyze the effects of programming education for the cultivation of creativity and personality. Our proposed model is expected to be used as a guide to establish creativity and personality for human resource cultivation in programming education.

한영신 보안공학연구지원센터(JSE) 2011 보안공학연구논문지 Vol.8 No.2
본 연구에서는 무선 환경 하에서 광범위하게 사용되고 있는 SM에 보안 기술을 적용하여 안전한 메시지 사용 환경을 구현하고 이를 위해 대칭키 방식의 보안 알고리즘인 DES를 적용하여 SMS를 구현한다. SMS는 DB 서버 모듈과 암호화/복호화 모듈 그리고 서버인터페이스 모듈로 구성되고 송신자 측에서 작성한 메시지가 암호화되어 SMS 서버의 데이터베이스에 저장된 후 수신자가 메시지를 수신하고 복호화하는 과정을 수행 하도록 한다. 또한, 암호화 및 복호화 시간을 단축하기 위해 XML을 활용하는 것이다. This paper aims at developing communication module and application program for client management module and developing database management module and managing wireless communication facilities for server systems. To construct these aims, we have adapted DES algorithm and researched on encrypting and decrypting module development applicable to SMS Security System and optimize module size and processing speed. In addition, the XML technology is applied to encrypt only the contents of the message in a way to reduce the volume of data to process and shorten the time to encrypting.
수율향상을 위한 반도체 EDS공정에서의 불량유형 자동분류

In the semiconductor manufacturing, yield enhancement is an urgent issue. It is ideal to prevent all the failures. However, when a failure occurs, it is important to quickly specify the cause stage and take countermeasure. Reviewing wafer level and composite lot level yield patterns has always been an effective way of identifying yield inhibitors and driving process improvement. This process is very time consuming and as such generally occurs only when the overall yield of a device has dropped significantly enough to warrant investigation. The automatic method of failure pattern extraction from fail bit map provides reduced time to analysis and facilitates yield enhancement. The automatic method of failure pattern extraction from fail bit map provides reduced time to analysis and facilitates yield enhancement. This paper describes the techniques to automatically classifies a failure pattern using a fail bit map.

The primary purpose of this study is to build computer models referring overall flow of complex and various semiconductor wafer manufacturing process and to implement a educational model which operates with a presentation tool showing device design. It is important that Korean semiconductor industries secure high competitive power on efficient manufacturing management and to develop technology continuously. Models representing the FAB processes and the functions of each process are developed for Seoul National University Semiconductor Research Center. However, it is expected that the models are effective as visually educational tools in Korean semiconductor industries. In addition, it is anticipated that these models are useful for semiconductor process courses in academia. Scalability and flexibility allow semiconductor manufacturers to customize the models and perform simulation education. Subsequently, manufacturers save budget.
수율향상을 위한 반도체 공정에서의 RRAM (Redundant Random Access Memory) Spare Allocation
한영신,Han, Young-Shin 한국시뮬레이션학회 2009 한국시뮬레이션학회 논문지 Vol.18 No.4
This has been possible by integration techniques such as very large scale integration (VLSI) and wafer scale integration (WSI). Redundancy has been extensively used for manufacturing memory chips and to provide repair of these devices in the presence of faulty cells. If there are too many defects, the momory has to be rejected. But if there are a few defects, it will be more efficient and cost reducing for the company to use it by repairing. Therefore, laser-repair process is nedded for such a reason and redundancy analysis is needed to establish correct target of laser-repair process. The proposed CRA (Correlation Repair Algorithm) simulation, beyond the idea of the conventional redundancy analysis algorithm, aims at reducing the time spent in the process and strengthening cost competitiveness by performing redundancy analysis after simulating each case of defect.

The purpose of this study is to find out the difference of Communication between Fathers and Children of according to family-environmental variable and the difference of Children's alienation according to Communication between Fathers and Children. Subjects of this study were 570 children in Seoul. Data were analyzed by One-way ANOVA and Two-way ANOVA. Results of this study are as follows; First, in the case of male, family-environment variables that influenced Communication between Fathers and Children were income. In the case of female, family-environment variables that influenced Facilitative Communication between Fathers and Children were income and father's scholarship. Second, in the case of male, family-environment variables that influenced Children's alienation were none. In the case of female family-environment variables that influenced Children's alienation were father's age and income. Third, Communication between Fathers and Children was a significant variable that influenced Children's alienation. When Fathers communicate facilitatively, Children feel less alienation. However when Fathers communicate dysfunctionally, Children feel more alienation. Forth, there was no interaction of Facilitative Communication and Dysfunctional Communication between Fathers and Children in the alienation.
