Recently, playing musical instruments in the application or website which is a sort of playing has been catching on for ordinary people even though they don't know how to play musical instruments. It appears that such playing has randomness which is quite natural. Thus, 'Random operation method' which induces the observing audience and changes them to manage actively is developed and suggested for the image system in this paper by utilizing Launch Pad, based on theoretical background and case analysis. Step Sequencer was developed in two ways: the image system is realized with Step Sequencer by connecting external program or made as clips to arrange them for each key on Launch Pad and implement, which is keyboard launch type.

In recent years, various virtual reality contents have been explosively developed, and the 'chance operation' in previous studies was mentioned. This study tries to implement the Step Sequencer in the virtual reality. Through the theoretical background analysis and case studies of virtual reality, three major experiential values such as Value of Overcoming Constraints, Value of Strengthening Experience, and Value of Creating New Experience were induced. A convergencestep sequencer with the presence and immersion elements was developed and presented so that the music contents divided into 4 areas can be understood easily controlled more conveniently while keeping the identity of the step sequencer. It is expected that various convergence VR contentscan be developed in the future studies.

Recently, many musical instrument mobile apps have been released targeting normal people who can't play musical instrument at all. The reason of developing video system based on step sequencer are as follows; first, users can freely play the musical instruments; second, induce multiple users to play; and third, develop and suggest new step sequencer fused with the video. To resolve issue in video synchronization caused by sync issues when operating multiple step sequencers, the Pocket Operator of Teenage Engineering was used to realize multiply-connected step sequencer and also, the ultimate video system was developed through Mira-Web for multiple participation. In addition, it's required to make the Pocket Operator as software and receive various feedbacks to continue and complement study in order to develop the better video system.

In Korea Basic Science Institute(KBSI) the remote data analysis system is developed for the joint use of advanced equipments. This system enables the researchers to access the datas which are produced at KBSI and analyse them by Java program on the Web,. Except Web browser such as Internet Explorer or Netscape Navigator no additional softwares are required for analysing data. We have developed remote data analysis systems for five major equipments which KBSI supports for the researchers, The systems which are developed are those for NMR spectrometer High Reso-lution Tandem mass Spectrometer Microscopic Imaging System DNA Sequencer and Natural Ra-dioactivity Measruement System, These programs work on any computer platform and any operat-ing system only if the internet is available. This remote data analysis system will be served as a part of Collaboratory the remote collaborative system.

The major objective of this paper is the design of control unit based on the bit slice technique. The branch control unit is device that provides 16-way branch when used in conjuction with the Microprogram Sequencer. The Next address control unit is designed specifically for next address control of the Microprogram Sequencer.

In this paper, a floating-point processor which satisfied the subset of the proposed IEEE standard has been designed and realized by TTL chips. This processor consists of a floating-point arithmetic unit and a control sequencer. AHPL has been used in the design of sequencer. The execution times for the arithmetic operations were measured and compared with other microprocessor. The results had shown faster operations compared to the Z-80 processor. Though this processor was built by TTL chips, it could be fabricated as a one-chip processor.

In this paper, we design the memory tester chip playing an important role in the memory tester as central parts. Memory tester has the sixteen inner instructions to control the test sequence and the address and data signals to DUT. These instructions are saved in memory with each block such as sequencer and pattern generator. Sequencer controls the test sequence according to instructions saved in the memory. And Pattern generator generates the address and data signals according to instructions saved in the memory, too. We can use these chips for various functional test of memory.

본 논문에서는 ASR(Arithmetic Shift Register)과 SHA-2로 구성된 32비트 출력의 새로운 스트림 암호 ASC를 제안한다. ASC는 소프트웨어 및 하드웨어 구현이 쉽게 디자인된 스트림 암호 알고리즘이다. 특히 계산능력이 제한된 무선 통신장비에서 빠르게 수행할 수 있도록 개발되었다. ASC는 다양한 길이(8-32바이트)의 키를 지원하고 있으며, 워드 단위로 연산을 수행한다. ASC는 매우 간결한 구조를 가지고 있으며 선형 궤환 순서기(Linear Feedback Sequencer)로 ASR을 적용하였고, 비선형 순서기(Nonlinear sequencer)로 SHA-2를 적용하여 크게 두 부분으로 구성되어 있는 결합 함수(combining function) 스트림 암호이다. 그리고 8비트, 16비트, 32비트 프로세스에서 쉽게 구현이 가능하다. 제안한 스트림 암호 ASC는 최근에 표준 블록 암호로 제정된 AES, ARIA, SEED등의 블록 암호보다는 6-13배 빠른 결과를 보여주고 있으며, 안전성 또한 현대 암호 알고리즘이 필요로 하는 안전성을 만족하고 있다.
