Searched a theory of North-Korean drama, divided in two periods in respect of historicism. The first period, as that of Korean War, is when a theory of drama has a tendency to revolutionary romanticism. It seems that this tendency is influenced by the effect of lofty realism, presented to creation methodology from an age of liberation. And, in this period, only being created for the purpose of victory in the war, drama cannot help being created on the ground of non-conflict theory as a perfect victory of positive protagonist rather than ideological trouble. So, work, which is left by remains of formalism or naturalism, is to be a critical object and dramatizes only a positive protagonist. In the second period, from Korean War to 1958, a theory of drama is social realism. In this time, it criticizes schematism caused from an intentional conflicts, reflecting that the previous drama wasn`t written by a realistic creative method. it not only shows such a social-realism as in a roundabout way of causing an interest, but emphasizes, refering to each concrete element in drama(character, speech, etc), that should create alive character, throwing unrealistic, abstract tendency. When, however, it reaches stage of guiding criticism through subcommittee, the limitation theory of North-Korean drama, will realistically be shown. In other words, it is because that art is to be only accessories as simply by a guidance theory. After 1958, this appearance is more accelerated and revolutionary opera is occurred, showing a wrong execution of national form. As a result of searching a theory of North-Korean in 1950s, divided in two periods, we can know that revolutionary romanticism shifts to social-realism and that is a previous stage to go Ju-the idea afterwards. That is to say, this is because that a view of the world shifts from Marxism-Leninism to anti-Japan revolutionary tradition and is finally to be a one-man dictatorship.

호흡운동 조절 방사선치료 시 환자체표면 움직임을 추적하여 실시간 보정하고자 한다. 본 연구에서 사용한 시스템은 치료테이블에 기반을 둔 동 팬텀(CBMP, couch based computer-controlled motion phantom), 초음파 센서 및 제어, 구동, 분석 프로그램 등으로 구성하였다 동물실험 결과 호흡주기는 2.9초이었고, 호흡진폭은 6mm이었다. 실시간 체표면 추적시스템의 유용성 평가에 중요한 항목인 호흡운동 획득-보정간의 지연시간은 $2.34{\times}10^{-4}sec$ 초이어서 호흡운동 조절 방사선치료 시 사용할 수 있는 새로운 실시간 체표면 추적 기술의 임상적용에의 가능성을 확인할 수 있었다. Respiration sating radiotherapy technique developed In consideration of the movement of body surface and Internal organs during respiration, is categorized into the method of analyzing the respiratory volume for data processing and that of keeping track of fiducial landmark or dermatologic markers based on radiography. However, since these methods require high-priced equipments for treatment and are used for the specific radiotherapy. Therefore, we should develop new essential method whilst ruling out the possible problems. This study alms to obtain body surface motion by using the couch based computer-controlled motion phantom (CBMP) and US sensor, and to develop respiration gating techniques that can adjust patients' beds by using opposite values of the data obtained. The CBMP made to measure body surface motion is composed of a BS II microprocessor, sensor, host computer and stopping motor etc. And the program to control and operate It was developed. After the CBMP was adjusted by entering random movement data, and the phantom movements were acquired using the sensors, the two data were compared and analyzed. And then, after the movements by respiration were acquired by using a rabbit, the real-time respiration gating techniques were drawn by operating the phantom with the opposite values of the data. The result of analysing the acquisition-correction delay time for the data value shows that the data value coincided within 1% and that the acquistition-correction delay time was obtained real-time $(2.34{\times}10^{-4}sec)$. And the movement was the maximum movement was 6 mm In Z direction, In which the respiratory cycle was 2.9 seconds. This study successfully confirms the clinical application possibility of respiration gating techniques by using a CBWP and sensor.

난수 생성 함수는 소프트웨어를 사용한 시뮬레이션 테스트나, 통신 프로토콜 검증 등 수많은 어플리케이션에 사용되어진다. 이런 상황에서 난수의 randomness는 사용 어플리케이션에 따라서 다르게 필요할 수 있다. 반드시 randomness가 보장된 랜덤 함수를 통한 고품질의 난수를 생성해야 할 때가 있고, 단지 난수와 비슷한 형태를 가진, randomness가 보장되지 않은 난수가 필요할 때도 있다. 본 논문에서는 고속으로 동작하는 임베디드 시스템을 위한 듀얼 모드로 동작하는 하드웨어 난수 생성기를 제안하였다. 모드1 에서는 높은 randomness를 가지는 난수를 6사이클마다 한 번씩 생성하게 되며, 모드 2 에서는 낮은 randomness를 가지는 난수를 매 사이클마다 생성할 수 있다. 테스트를 위해, ASIP(Application Specific Instruction set Processor)를 설계하였으며, 각 모드에 맞는 명령어 세트를 설계하였다. ASIP은 LISA언어를 사용하여, 5 stage MIPS architecture를 기반으로 설계되었고, CoWare 사의 Processor Generator를 통해서 HDL코드를 생성하였으며, HDL 모델은 동부 0.18㎛ 공정으로 Synopsys사의 Design Compiler를 통해서 합성되었다. 설계되어진 ASIP으로 난수를 생성한 결과, 하드웨어 모듈을 추가하기 전에 비해 2.0%의 면적 증가 및 239%의 성능 향상을 보였다. Random numbers are used in many sorts of applications. Some applications, like simple software simulation tests, communication protocol verifications, cryptography verification and so forth, need various levels of randomness with various process speeds. In this paper, we propose a fast pseudorandom generator module for embedded systems. The generator module is implemented in hardware which can run in two modes, one of which can generate random numbers with higher randomness but which requires six cycles, the other providing its result within one cycle but with less randomness. An ASIP (Application Specific Instruction set Processor) was designed to implement the proposed pseudorandom generator instruction sets. We designed a processor based on the MIPS architecture,, by using LISA, and have run statistical tests passing the sequence of the Diehard test suite. The HDL models of the processor were generated using CoWare’s Processor Designer and synthesized into the Dong-bu 0.18㎛ CMOS cell library using the Synopsys Design Compiler. With the proposed pseudorandom generator module, random number generation performance was 239% faster than software model, but the area increased only 2.0% of the proposed ASIP.
