Radix-4^2 알고리즘을 사용한 저면적 FFT 프로세서 구조

김한진,장영범 대한전자공학회 2012 電子工學會論文誌-SD (Semiconductor and devices) Vol.49 No.3

In this paper, a low-area FFT structure using Radix-4^2 algorithm is proposed. The large point FFT structure consists of cascade connection of the many stages. In implementation of large point FFT using Radix-4^2 algorithm, stages which number of different coefficients are only 3 appear in every 2 stages. For example, in the 4096-point FFT, the stages that number of different coefficients are 3 appear in stage 1, 3, and 5 among 6 stages. Multiplication block area of these 3stages can be reduced using CSD(Canonic Signed Digit) and common sub-expression sharing techniques. Using the proposed structure, the 256-point FFT is implemented with the Verilog-HDL coding and synthesized by 1.971㎟ cell area in tsmc 0.18㎛ CMOS library. This result shows 23% cell area reduction compared with the conventional structure. 이 논문에서는 Radix-4^2 알고리즘을 사용한 저면적 FFT 구조를 제안한다. 큰 point의 FFT는 여러 개의 직렬연결 스테이지로 구성되는데, Radix-4^2 알고리즘을 사용하면 매 2 스테이지마다 곱셈 종류의 수가 3인 스테이지가 생긴다. 이 사실을 이용하여 곱셈 연산 종류의 수가 3인 스테이지의 구현 면적을 줄이는 구조를 제안하였다. 예를 들면 4096-point FFT는 6개의 스테이지로 구성되는데 Radix-4^2 알고리즘을 사용하면 3개의 스테이지가 곱셈연산 종류의 수가 3이다. 이 3개의 스테이지의 곱셈연산 하드웨어는 CSD(Canonic Signed Digit) 계수 방식과 CSS(Common Sub-expression Sharing) 기술을 사용하여 구현면적을 감소시킬 수 있었다. 제안된 방식을 사용하여 256-point FFT 구조를 설계하여 Verilog-HDL 코딩하였다. 또한 tsmc 0.18 ㎛ CMOS 라이브러리를 사용하여 합성하여 구현한 결과 1.971㎟의 cell area를 얻었다. 이와 같은 합성 결과는 기존 구조와 비교하여 약 23%의 cell area 감소 효과를 보였다.

Preschool have been increasing Recently with an early education and mitigation of establishment. In case of Jeju city, there are 30 present of all preschool of Jeju-do and 45 percent of all classroom are concentrated in Jeju city. Though various preschool, like, pace using by remodeling of existed elementary classroom are increasing, it is not many about research and analysis of the present condition of preschool, especially about of an analysis of building scale and nursery room and playing room. This study is focused on an analysis of building scale and nursery room and playing room and all preschaal in Jeju city. This study is consisted of two steps. 1n first step, it was measured of plan anrt understand scale, plan type and so on. In second step, it was a question research to the management of preschool. A result of analysis are as following; 1. Most of preschool under 300 are complex with other facilities like church and elementary, and so on and its ail are public preschool. 2. In case of public preschool, many of preschool are under proper scale and especially nursery room are under proper scale. 3. And playing property of planning of playing roam are no good than its of nursery room.

김한진,김진환 한국국가안보국민안전학회 2020 한국국가안보·국민안전학회지 Vol.11 No.-

본 연구는 국가와 국민의 안전을 위하여 민간경호원과 공경호원들에게 실질적이고 효율적인 경호업무 수행을 하기 위한 물리적 대응으로서 태국 무에타이 기술을 경호무도 수련 체계에 적용방안으로 제시하는데 그 목적이 있다. 이에 따라 관련 전문가들을 직접 인터뷰 하였으며, 경호무도 수련에 적용하기 위한 학문적 접근을 시도하였다. 경호상황시 우발적 인 물리적 상황에서 경호원의 효과적인 경호임무를 수행하고자 무에타이 기술의 적용을 목적으로 하고 있으며, 4개의 전문가 그룹(민간경호 실무자, 공경호 실무자, 무에타이 전문 가, 경호무도 교수)의 의견을 적극적으로 수렴할 수 있는 탐색적 기초연구방법인 심층면담 기법을 사용하였다. 참여대상자와는 개별면담을 통하여 녹취 및 질문지를 통해 심층적으로 연구 분석하였다. 본 연구에서는 경호무도로서 무에타이 기술을 적용하고자 방법을 제시하 였다. 첫째, 무에타이는 다른 무도에 비하여 수련방법에 실전성이 우수하며, 화려한 기술체 계 보다는 실전적인 방향으로 발전되어 왔다. 둘째, 무에타이 기술에 있어 학문적인 연구는 아직 부족한 실태이다. 무에타이 기술의 대중화와 공인 무도로의 발전이 이루어지고 있는 실정에서 무에타이 기술의 통합 교본이 마련되어 표준화된 교재로 연구되어야 할 것이다. 셋째, 앞으로 경호무도로서 무에타이를 실무에 적용할 수 있도록 연구, 개발을 통하여 경호 무도로서 실효성을 인정받아야 할 것이며, 독립된 경호 무도로서 교육이 이루어질 수 있도 록 체계적인 방안을 정립하여야 한다. 넷째, 경호무도로서 무에타이 기술을 경호 우발상황 시에 적용하여 실무에 적합한 기술 동작을 측정도구로서 객관적이며 타당성 있는 접근방 법이 필요하다. The purpose of this study is to present Thai Muay Thai technology as a method of application to the security martial arts training system as a physical response to practical and efficient security work for private and public security guards for the safety of the country and the people. Accordingly, relevant experts were directly interviewed, and an academic approach was attempted to apply to the training of the guards. In the case of a security situation, the purpose of applying Muay Thai technology is to perform effective security duties of the security guard in an accidental physical situation. In-depth interview technique was used, which is an exploratory basic research method that can converge. In-depth research and analysis were conducted with participants through individual interviews through recording and questionnaire. In this study, a method was proposed to apply Muay Thai technique as a guard martial arts. First, Muay Thai has superior practicality in training methods compared to other martial arts, and has been developed in a practical direction rather than a brilliant technical system. Second, academic research on Muay Thai technology is still insufficient. With the popularization of Muay Thai technology and the development of official martial arts, an integrated textbook of Muay Thai technology should be prepared and studied as a standardized textbook. Third, in order to apply Muay Thai as a security martial arts practice in the future, the effectiveness as a security martial arts should be recognized through research and development, and a systematic plan should be established so that education can be achieved as an independent security martial art. Fourth, as a security martial arts, an objective and valid approach is needed as a measuring tool to apply the Muay Thai technique in case of a security contingency situation and to measure the technical behavior suitable for practice. Although this study is currently in the trend of popularization and development, it is meaningful to study a plan that can apply Muay Thai technology, which requires theoretical establishment of technology and academic research, to security martial arts.

아동의 자아개념과 가정에서의 참여권 실현 정도-초등학교 5학년 아동을 중심으로-

김한진 한국교육개발원 2002 한국교육 Vol.29 No.2

On this study, the views of justifying to restrict the children’s rights of participation have been critically examined and it has been investigated how they exercise their rights of participation in the family circumstances. The sampling subjects for the research were a total of 430 pupils(male 225, female 205) in the 5th grade of primary schools in Seoul, Daejeon, Sungnam and Tongyoung. The instrument for participation consists in three domains, self-related, family members-related, activity-related participation in the family circumstances. The instrument measuring for self-concept recomposed by the researcher consists in four domains, i.e., cognitive, social, psycho-motor and affective domains. The results of the study are shown as follows; Firstly, the significant results have been found as follows:the high scores about the rate of participation rank by male children rather than female children, those in metropolitan rather than other areas, and so on. Secondly, the socal self-concept is statistically significant variable for all subjects and all sub-domains of participation. With regard to the relationship self-concept and participation it shows statistically significant difference in accordance with children’s gender. Only for male, the affective self-concept has effect on family members-related participation. Only for female, the psycho-motor self-concept has an effect on self-related participation. 본 연구의 목적은 아동에게 가장 중요한 사회적 공간인 가정생활영역에서 아동이 지각하는 자아개념에 따라 아동의 참여권이 어떻게 실현되고 있는가를 분석하는 데 있다. 본 연구의 결과를 정리하면 다음과 같다. 첫째, 아동의 일반적 특성에 따른 전체 참여권의 실현정도(이하 ‘참여도’로 표기)를 살펴보면, 남아보다는 여아가, 특별시에 거주하는 아동과 출생순위가 높은 아동, 조부모와 동거하지 않는 아동, 전세를 사는 아동의 참여도가 높게 나타났다. 둘째, 성별에 따른 아동의 자아개념과 참여도의 관계에서 남아, 여아 모두 참여의 모든 하위요인에서 사회적 자아가 가장 강력한 영향력을 미치는 예측변인이었다. 참여도의 하위요인들 중 남아와 여아의 차이가 뚜렷한 영역은 자아관련 영역과 가정사관련 영역이었다. 자아관련 영역에서 여아의 경우만 신체적 자아가, 가정사관련 영역에서 남아의 경우만 정의적 자아가 참여권의 실현 정도와 관련이 있는 것으로 나타났다.
