중학교 정보 교과서에서 "문제해결 방법과 절차" 영역의 창의적 문제해결력 경향 분석

김용대 ( Yong Dae Kim ),최길수 ( Gil Su Choi ),이종연 ( Jong Yun Lee ) 한국컴퓨터교육학회 2012 컴퓨터교육학회 논문지 Vol.15 No.1

정보 교과는 지식정보화 사회에 필요한 정보 활용 능력은 물론 창의적인 문제해결력을 함양하기 개설된 교과이다. 그러나 창의적 문제해결요소가 교과서에 어느 정도 포함되었는지를 분석하는 연구는 미미하다. 따라서 본 논문은 중학교 정보 1 교과서 ``문제해결방법 및 절차`` 영역의 창의적 문제해결력 경향을 정량적으로 분석하였다. 정보 교과서가 창의적 문제해결력 함양 요소를 어느 정도 포함하고 있는지 최길수의 정량적 분석법으로 분석한 결과, 교과서별로 문제해결과정 반영과 문제해결전략 제시의 충실도에 차이가 크게 나타났고 모든 교과서가 활동 요구 지수, 창의적 문제해결력 관련지수, 활동 유형지수가 전체적으로는 바람직한 범위에 있으나 소 영역별로는 바람직한 범위를 벗어난 것이 있는 것으로 나타났으며 지수 값이 균형을 이루지 못한 교과서가 있고 활동 유형이 일부 유형에 치우쳐 있는 것으로 나타났다. 그러므로 앞으로 정보 교과서의 개발 및 수정 보완 시 문제해결과정 반영과 문제해결전략의 충실도를 높이고, 교과서의 학습 활동 구성 시 다양한 학습 활동 유형을 활용하고 기본 정신 기능과 고등 정신 기능을 요구하는 활동 비율의 균형을 유지할 것을 제안하였다. Developing middle and high students` information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether ``problem-solving methods and procedures`` parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection` and "problem-solving strategy proposal". Also a few textbooks haven`t satisfied in important indexes and activities. So, we suggest that more ``problem-solving process reflection`` and ``problem-solving strategy proposal`` parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.

靑少年의 感覺把持에 對한 實驗的 硏究

申吉洙 圓光大學校 1980 論文集 Vol.14 No.2

In order to attempt to carry out the experimental study on the sensory grasp of the youth. I measured the revival ability of the sensory grasp against 159 boys and girls before movement, and remeasured that ability after giving the motion hurden of twice 400 meters. As a resuet of the comparatine analysis of those statistics before and after movement, the following conclusion was reached : 1. As compared with before movement the skin sense diminished the records of the error distance at the pressure point, that is, 0.12cm of boys and 0.07cm of girls, and the spase sence made the error distance, that is, 0.15cm among boys more cor-rect, but expanded the error distance, that is, 0.15cm among girls. 2. In the position sense, the measurement value from an angle of 45 degrees was better 0.2 to 0.63cm ofter movement than before movement. And the rate of app-earance increased 8.00% among girls as the accurate measurement groups. 3. The grasp sence on the sustaining hour of movement was more accurate 0.26 sec. among boys after movement than before movement, and the appearance rate showed more accurate vale of measurement, that is, 5% among boys and 20% among girls. 4. The grasp revival ability of pressure resistant sense showed much better reco-rds of the left hand than those the right thand through before and after movement, And was more accurate after movement then before movement, that is, 14.2g among boys and 15.11g among girls, The appearance rate didnt change through before and after movement among boys, and showed more accurate value of meas-urement, that is, 34.0% among girls after movement than before movement. 5. The grasp ability of the equilibrium sense did nat show the difference of the average value, but diminished 4.2% among girls after movement in comparison with before movement and showed the disorder.

본 연구에서는 산업용 로봇 시스템의 정밀도 및 견실성을 향상시키기 위하여 자기구성 퍼지제어 알고리즘을 개발하여 디지털 신호 처리기에 기초한 관절제어기를 설계하고 이의 실시간 제어실현에 대한 연구가 수행되었다. 제안된 자기구성 퍼지 제어기는 적절한 제어입력을 출력하면서 환경을 관측하고 이 제어입력으로 인한 결과를 이용하여 다음에 나올 결과를 향상시킨다. 그러므로 자기구성 퍼지 제어기를 이용하면 환경에 대한 최소의 정보만을 가지고도 견실 제어기를 설계할 수 있다. 본 논문에서는 조정인자와 규칙을 동시에 수정하여 제어규칙이 점근적으로 수렴하면서 수렴속도를 향상시킬 수 있는 자기구성 퍼지 제어기를 제안하였다. 제안된 자기구성 퍼지 제어기는 위에서 언급한 바와 같이 퍼지 제어기의 단점을 보완하는 측면이 있기 때문에 성능향상을 기대할 수 있다. 따라서, 본 논문에서는 퍼지추론기능과 퍼지규칙 조정능력을 갖는 퍼지 알고리즘을 개발하고 외부환경의 변화 즉, 제어대상인 플랜트의 파라미터변화 및 부하의 변동에 대해서도 능동적이고 우수한 제어성능이 유지될 수 있는 고정도 산업용 로봇 제어기 설계기법을 제안하고, 수직다관절(AM1)로봇에 대한 시뮬레이션 및 실험을 통해 그 성능을 검증하였다. In this paper, it is presented a new technique to the design and real-time implementation of fuzzy control system based-on digital signal processors in order to improve the precision and robustness for system of industrial robot. Fuzzy control has emerged as one of the most active and fruitful areas for research in the applications of fuzzy set theory, especially in the real of industrial processes. In this thesis, a self-organizing fuzzy controller for the industrial robot manipulator with a actuator located at the base is studied. A fuzzy logic composed of linguistic conditional statements is employed by defining the relations of input-output variable of the controller, In the synthesis of a FLC, one of the most difficult problems is the determination of linguistic control rules from the human operators. To overcome this difficult, SOFC is proposed for a hierarchical control structure consisting of basic level and high level that modify control rules.

According to increasing need of ocean development, it is necessary for the dynamic analytical method of moored floating bodies. The 2-D problem of moored floating objects was solved numerically as a boundary value problem by direct use of Green's identity formula for a potential function by Ijima et al. They treated floating bodies having mono-hull with taut mooring system for shallow water. In this paper, Ijima's method was extended to catamaran with catenary mooring system for deep water. The dynamic characteristics of catamaran with catenary mooring system showed good agreement with Simada's result. v

윤길수,김동준 釜山水産大學校 1985 釜山水産大學 硏究報告 Vol.25 No.2

본 연구의 결과를 요약하면 다음과 같다. 1. 복소수를 포함하는 선형연립방정식을 푸는 한 방법으로서 부분행렬과 Choleski의 직접해법을 이용한 새로운 프로그람을 작성하였다. 2. 복소수가 정의되지 않는 개인용 전산기에서도 복소수를 포함한 선행연립방정식을 풀 수 있다. 3. 부유체의 운동해석 과정 중에서 2차원 유체력을 구하는 부분에 본 계산방법을 이용할 경우 기억공간이나 계산시간이 줄어들게 된다. 4. 부유체의 운동방정식의 해법에 본 계산방법을 이용할 경우 계산과정이 간단해지게 된다. 5. 본 계산방법은 Gauss 소거법과 비교할 때 기억공간이나 계산시간이 적게 요구된다. This paper presents an application method of personal computer for the motion analysis of Floating Bodies. For the solution of linear equations with complex coefficients, a new computational procedure is formulated and programmed using partitioning and Choleski decomposition. The method is implemented in the personal computer which can not define complex variables. From the case study, it is found that the method is efficient in the motion analysis of floating bodies, especially in the calculation of 2nd hydrodynamic coefficients. Comparison with the Gauss elimination method shows that the proposed new method requires small memory size less computing time.

계산하기가 비교적 어렵고, 정시간을 요하는 반잠수 해상구조물에 미치는 波力을 Hooft의 근시방법을 이용하여 계산하였다. 본 계산방법에 의하면 간단한 계산만으로도 波기진력 추정이 가능할 뿐만 아니라 소요되는 계산시간이 짧은데 비해 계산 결과도 실험치와 잘 일치하고 있다. 다라서 초기 설계 단계의 해양구조물의 波기진력 계산에 이용할 수 있으며, 운동계산에의 이용도 가능할 것이다. 더구나 본 계산은 Apple CP/M fortran으로 작성, 수행되었음을 밝힌다. 아울러, 대형전산조직의 사용을 절감시킬 수 있을 것으로 기대된다. This paper presents an approximation method for wave force on semi-submersible platforms. The approximate values for 2-D circular cylinder added masses and calculation method was made use of the Hooft's works. The procedure was computerized and varified with the STAFLO platform. The calculation results were compared with the experimental data of NSMB and showed nearly same values.
