훈민정음 창제당시의 모든 한글 음절인 약 399억 음절을 표현하기 위해서 자소형 코드만을 입력하여 이를 조합 음절 형태로 구성하고, 최적 폰트 코드를 출력함으로써 모든 한글을 표현할 수 있었다. 하지만, 이러한 최적 폰트 코드는 모든 한글을 표현하는 데에만 치중하였지만, 키보드로부터 입력되는 자소형 코드와 화면에 음절을 구성하며 출력되는 폰트 코드의 일치하지 않는 문제점이 발생하였다. 이를 해결하기 위해서 본 연구에서는 실험을 통하여 입력된 자소형 코드를 파일입출력을 이용하여 파일로 저장 후 이를 본 연구에서의 옛한글 입력기의 폰트 변환 모듈을 사용하여 음절을 표현하여, 자소형 코드와 폰트 코드와의 일치함을 보이고자 한다.

유니코드에 있는 3가지 한글코드를 훈민정음의 과학적 원리를 기준으로 정비하기 위하여 각각을 분석해서 평가한 다음 훈민정음 창제원리를 반영한 정음형 코드 즉 한글자모 코드가 나머지 음절표현을 포괄한다는 결과에 따라서 U+1100만 남기고 나머지 공간은 반납해야 한다는 정비 방향을 제안한다.

1990년대에 들어 컴퓨터 시스템의 급진적 발전으로 인한 소형 컴퓨터의 성능 향상과 가격 하락으로 보급량이 증가하고, LAN/WAN 및 인터넷 통신 기술 발달에 힘입어 여러 분야에서 많은 응용들이 클라이언트/서버 환경에서 개발되고 있다. 클라이언트/서버 환경을 도입하는 이유는 개방형 시스템으로서의 표준화와 자원 공유, 확장성, 가용성, 응용의 생산성 등의 장점 때문이다. 클라이언트/서버 환경에서 운용되는 대부분의 프로그램은 다계층 구조에서 표현계층(사용자 인터페이스) , 응용 로직, 그리고 데이카로 나뉘어질 수 있다. 클라이언트/서버 환경에서 최적의 성능을 얻기 위해서는 어느 자원을 어디로 분산하여야 하는가 하는 것이 문제가 된다. 만약 개발자가 코딩 단계에서 각 노드의 시스템의 부하 정보를 얻을 수 있다면, 클라이언트/서버 환경에서 부하가 적절히 분산된 최적의 프로그램임을 쉽게 개발할수 있다. 본 연구에서는 자바 소스 코드의 분석을 통하여 시스템 부하를 측정할수 있는 시뮬레이터를 개발하였다. 시뮬레이터는 시스템 환경 변수와 자바 소스 코드를 받아들여 모의실험한 후, 응답시간을 라인 그래프 및 막대그래프의 형태로 표현한다. 마지막으로, 시뮬레이터의 정확성을 검증하기 위하여 임의의 프로그램을 선택하여 설제 실행 시간과 본 시뮬레이터에서 측정된 응답시간을 비교, 분석하였다.

The traditional small educational multi-joint robots were developed on firmware. In these system's case, we cann't give a chance to educate good practices due on executing just robot's simple movements. But it may be possible for RTOS to control the elaborate movement of the robot with assembling each part on firmware. With this RTOS, we can enhance the efficiency of robot's movements, but too difficult to use the education as increasing the complexity of robot system. To solve the problem, we apply with Design pattern and Refactoring for the Education. Applying robot's design with Design pattern and Refactoring. There may be easily understand what and how to design RTOS for any level ones. We may easily change/upgrade RTOS for new system with this approach. This paper mentions to design RTOS with Design patterns and to apply RTOS's source code with Refactoring.

In a wireless sensor network environment, it is required to ensure anonymity by keeping sensor nodes' identifiers not being revealed and to support real-time authentication, lightweight authentication and synchronization. In particular, there exist possibilities of location information leakage by others, privacy interference and security vulnerability when it comes to wireless telecommunications. Anonymity has been an importance issue in wired and wireless network environment, so that it has been studied in wide range. The sensor nodes are interconnected among them based on wireless network. In terms of the sensor node, the researchers have been emphasizing on its calculating performance limit, storage device limit, and smaller power source. To improve of biometric-based D. He scheme, this study proposes a real-time authentication protocol using Unique Random Sequence Code(URSC) and variable identifier for enhancing network performance and retaining anonymity provision.

In this paper, We use the APL as IDL when simulation a 16-bit SIP. It was possible for IDL to represent and describe a structure of a H/W which other HDL have not. Because We partitioned whole system to various modules when desingning processor, We adpoted a direct decoding method. A designed each modules are executed according to 12-bit control word was inputed through experimental framework, Which were composed to symbolized instructions. In here, By setting instruction codes of the SIP using binary code, We composed instruction format and assembler instruction, and verified the SIP behaviour that try to implement by entering a presented instruction set through experimental framework. In a presented SIP, Because inputing program are a symbolized language, Designer and user will easily understand behaviour of system. Especially, Because we can immediatly specify a unit function within SIP, We will use variously and easily the library cell.

Games in 1970s have used the savings of analog wavelength as in music and the like on hardwares of small cassette, gramophone, and the like. Due to these configuration elements, durability has to be declined so much. In the event of using the music on the video game, more affordable method is to use the computer chip to convert the analog sound into the computer code to convert into the electric wavelength to send to the speaker. The sound effect of the game is generated in this method. The technical limit has been gradually overcome to grant more freedom to the composers and the sound track pre-recorded on the optic disc and the like has emerged. The game developers of today have made several attempts on the technology to produce the game music. This study has contemplated the process of advancement in the change of game music production with the influence on technology and business.

Purpose: This study was conducted to explore the experience of smart-home healthcare among older adults who had participated in the smart-home technology development project. Methods: Data were collected by focus group interviews with 7 hypertension or diabetes participants(mean age 75 years). Qualitative contents analysis was used to analyze the verbal data. Results: The results were composed of 27 meanings units, 10 categories and 6 themes. The 6 themes are: 'improvement of health conditions through anytime anywhere self-monitoring', 'attractive experience to be counselling at home', 'frequent system and telecommunication problems', 'unfamiliar devices for elderly users', 'complementary strategies for activation', 'advancement of elderly-friendly devices and programs'. Conclusion: The smart-home healthcare system should be developed based on older adults' preferences. It is essential to make progress with professional resources and organizational supports in the future.

Radiation-related practitioners and radiation-treated patients at medical institutions are inevitably exposed to radiation for diagnosis and treatment. Although standards for maximum doses are recommended by the International Commission on Radiological Protection (ICPR) and the International Atomic Energy Agency (IAEA), more direct and available measurement and analytical methods are necessary for optimal exposure management for potential exposure subjects such as practitioners and patients. Thus, in this study we developed a system for real-time radiation monitoring at a distance that works with existing portable device. The monitoring system comprises three parts for detection, imaging, and transmission. For miniaturization of the detection part, a scintillation detector was designed based on a silicon photomultiplier (SiPM). The imaging part uses a wireless charge-coupled device (CCD) camera module along with the detection part to transmit a radiation image and measured data through the transmission part using a Bluetooth-enabled portable device. To evaluate the performance of the developed system, diagnostic X-ray generators and sources of $^{137}Cs$, $^{22}Na$, $^{60}Co$, $^{204}Tl$, and $^{90}Sr$ were used. We checked the results for reactivity to gamma, beta, and X-ray radiation and determined that the error range in the response linearity is less than 3% with regard to radiation strength and in the detection accuracy evaluation with regard to measured distance using MCNPX Code. We hope that the results of this study will contribute to cost savings for radiation detection system configuration and to individual exposure management.
