정인기 한국정보교육학회 2014 정보교육학회논문지 Vol.18 No.2

정보화 사회에서 필요한 능력은 정보 능력을 바탕으로 한 문제 해결 능력의 습득이며 이러한 핵심 역량에 대한 교육 필요성과 함께 급변하는 정보화 사회에서 새로운 기술의 발전과 사회 환경의 변화로 인하여 교육 과정을 새롭게 구성해야 할 필요가 발생하였다. 따라서 한국정보교육학회에서는 정보 교과의 내용 체계에 대한 개정안에 대하여 연구하였으며, 정보 교육 내용을 ‘소프트웨어’, ‘컴퓨터 시스템’ 및 ‘융합 활동’의 세 영역으로 구분하였다. 이에 따라 본 논문에서는 ‘소프트웨어’ 영역의 ‘문제 해결’ 주제에 대하여 초등학교 1학년부터 중학교 3학년까지의 교육과정을 연구하였다. 먼저 ‘문제 해결’의 교육 내용을 ‘문제 이해 및 분석’, ‘데이터 관리’, ‘문제 해결 전략 수립’, ‘문제 해결 방법 탐색 및 개발’ 및 ‘문제 해결 방법 검토’ 등으로 분류하고 이에 대한 성취 기준을 제시하였다. 그리고 이 성취 기준을 도달하기 위한 교수 학습 방법과 평가 방안을 학년군 별로 세분화하여 제시하였다. 본 연구에서 제시한 ‘문제 해결’에 대한 교육과정은 정보화 사회에 필요한 인재 양성에 기여할 것으로 기대된다. We need problem solving abilities based on the information abilities in information-oriented society. New curriculum is demanded by new technology and circumstance to need the core competencies. Korea Association of Information Education has studied new curriculum and suggested new plans that contents of information education classified by ‘Software’, ‘Computer System’ and ‘Convergence Activities.’ Therefore, we studied on ‘Problem Solving’ topic of the ‘Software’ section of first grade to ninth grade. In this paper we firstly categorized ‘Problem Solving’ as ‘Problem Comprehension and Analysis’, ‘Data Management’, ‘Strategy Establishment for Problem Solving’, ‘Problem Solving Method Seeking and Development’ and ‘Examination of Problem Solving Method.’ We nextly suggested the achievement goals, teaching-learning methods and evaluation methods of ‘Problem Solving’ topic. We expect that the achievement goals and teaching-learning methods we suggested about ‘Problem Solving’ topic will contribute to training talented individuals.

The effects of the inclination of enclosure and partition on natural convective flow and heat transfer were investigated numerically. The enclosure was composed of the lower hot and the upper cold horizontal walls and the adiabatic vertical walls, and a partition was positioned perpendicularly at the mid-height of one vertical insulated wall. The governing equations are solved by using the finite element method with Galerkin method. The computations were performed with the variations of the partition length and Rayleigh number based on the temperature difference between two horizontal walls and the enclosure height with water(Pr=4.95). The effects of the inclination angle of enclosure and partition on the heat transfer within an enclosure were also studied. As the results, the increase of the inclination angle of enclosure rapidly raised the heat transfer rate, while the inclination angle for the maximum Nusselt number was retarded with the increase of the partition length and the decrease of the heat transfer rate became larger in proportion to the increase of the partition length. The Nusselt number obtained by the inclination of partition was smaller than that of the inclination of enclosure. However, the difference of the heat transfer rates was considerably decreased at the longer partition lengths and the trends for the variation of the average Nusselt number were more similar with that of the inclination of enclosure. The upward oriented partition increases the convective heat transfer distinctly in contrast to that of the inclination of enclosure as the partition length increases.

鄭仁基 영남이공대학 1973 論文集 Vol.2 No.-

The insulation structure of buildings is required for the reduction of heating fuel cost and comfortable indoor environment during the winter season, and it is the basic problem for insulating design to search the design condition and appropriate standard value through the analysis of regional climate conditions. This study aimed at developing the design of insulation structure of rural houses in Korea. For this purpose, the architectural climatic regions are classified by the analysis of regional climate conditions based on the weather records for the last ten years(1963-1972) in Korea, and the required conditions for insulating design and the standard value of insulating design pertaining to the building sections are calculated. Also, the over-all coefficient of heat transfer is calculated and measured for twenty test walls by the Guarded Hot Box type experimental apparatus. Thereby, the thermal insulation effect is reviewed and examples of insulation structure of rural houses are showed in reference with the Standard Design of Korean Rural Houses which is published by the Ministry of Construction. The conclusions of this study are as follows; 1. The architectural climatic region in Korea is shown as the Table 1, and its charts are shown as the Figures 1 to 3. 2. The effective temperature in winter which is calculated for 26 cities in Korea is shown as the Table 4, the climatic region pertaining to the effective temperature is shown as the Table 5. 3. The calculated normal heating degree-days(D) for 26 cities in Korea, the climatic region and diagram in terms of the normal heating degree-days are shown individually as the Table 6, Table 7 and the Figure 4. 4. The Table 8 shows the outdoor design ccxlitions of insulating design for the architectural climatic region. The standard values of the overall coefficient of heat transfer in terms of building sections which satisfy the outdoor design conditions in locality are shown as the Table 9. 5. The Figures 7 and 8 show the test walls, and values of their overall coeffici-ent of heat transfer which are calculated and experimented for the insulating structure of Korean rural houses. The relation between thickness and insulating effect for the air space and charged insulator with the building structures is shown as the Figure 9. 6. The Tables 10 and 11 show the calculated heating loads of heat transmission for both the original structure and insulated structure of the 15-1 Model House designed by the Ministry of Construction as the Standard Design of Korean Rural Houses. In comparision with the original structures, the insulated structures which satisfy the standard value of transmission coefficient in terms of building sections for the locality enable to reduce the heating fuel cost as much as 20%--30%. The Table 12 shows the estimated refunding years for the cost of the insulating construction, 7. The Table 13 shows the insulating plan in terms of the rural houses for architectural climatic regions, and the Figures 12 and 13 show their example designs.

Objective: The aim of this study was to investigate the effects of Joksamni(ST36) combination on NAD PH-diaphorase, neuronal nitric oxide synthase(nNOS), neuropeptide Y(NPY) and vasoactive intestinal peptide (VIP) in the cerebral cortex of spontaneously hypertensive rat. Methods: The experimental groups were divided into four groups: Normal, Joksamni(ST36), Joksamni(ST36)+Eumneungcheon(SP9), and Joksamni(ST36)+Gokji(LI11). Needles were inserted into acupoints at the depth of 0.5cm with basic insertion method. Electroacupuncture was done under the condition of 2Hz electrical biphasic pulses with continuous rectangular wave lasting for 0.2ms until the muscles produced visible contractions. Such stimulation was applied continuously for 10 minutes, 1 time every 2 days for 10 sessions of treatments. Thereafter we evaluated changes in NADPH-d positive neurons histochemically and changes in nNOS, NPY and VIP positive neurons immunohistochemically. Results: The optical densities of NADPH-d positive neurons of the Joksamni(ST36)+Eumneungcheon(SP9) group in all areas of cerebral cortex and Joksamni(ST36)+Gokji(LI11) group in primary somatosensory cortex, visual cortex, auditory cortex, perirhinal cortex were significantly increased as compared to the Joksamni(ST36) group. The optical densities of NADPH-d positive neurons of the Joksamni(ST36)+Gokji(LI11) group were significantly decreased as compared to the Joksamni(ST36)+Eumneungcheon(SP9) group with the exception of primary somatosensory cortex. The optical densities of nNOS positive neurons of the Joksamni(ST36)+Eumneungcheon(SP9) group in all areas of cerebral cortex and Joksamni(ST36)+Gokji(LI11) group in auditory cortex, perirhinal cortex, insular cortex were significantly increased as compared to the Joksamni(ST36) group. The optical densities of nNOS positive neurons of the Joksamni(ST36)+Gokji(LI11) group were significantly decreased in all areas of cerebral cortex as compared to the Joksamni(ST36)+Eumneungcheon(SP9) group. The optical densities of NPY positive neurons of the Joksamni(ST36)+Gokji(LI11) group were significantly decreased in primary motor cortex, primary somatosensory cortex, cingulate cortex as compared to the Joksamni (ST36) and Joksamni(ST36)+Eumneungcheon(SP9) groups. The optical densities of VIP positive neurons of the Joksamni(ST36)+Eumneungcheon(SP9) group were significantly increased in all areas of cerebral cortex except for cingulate cortex as compared to the Joksamni(ST36) group. The optical densities of VIP positive neurons of the Joksamni(ST36)+Gokji(LI11) group were significantly decreased in auditory cortex, cingulate cortex, perirhinal cortex as compared to the Joksamni(ST36) group. The optical densities of VIP positive neurons of the Joksamni(ST36)+Gokji(LI11) group were significantly decreased in all areas of cerebral cortex as compared to the Joksamni(ST36)+Eumneungcheon(SP9) group. Conclusions: The result demonstrated that electroacupuncture on Joksamni(ST36) and its combination change the activities of the NO system and peptidergic system in the cerebral cortex of SHR and that acupoint combination is one of the important parameters for the effects.

정렬 프로그래밍 교육을 위한 시각화 도구의 개발

정인기 한국컴퓨터교육학회 2004 컴퓨터교육학회 논문지 Vol.7 No.6

자료구조 및 알고리즘 분야는 컴퓨터 프로그래밍 교육의 기반이 되는 과목이다. 그러나 교육 방법이 현재의 추세인 비주얼 프로그래밍과 윈도우 프로그래밍 방법을 따라가지 못하여 학생들의 흥미를 유발하지 못하고 있다. 정렬 프로그래밍도 다른 자료 구조와 상황은 마찬가지이다. 이러한 문제점을 해결하기 위하여 본 논문에서는 교육자가 효과적으로 정렬 알고리즘을 교육할 수 있는 VTSPI (Visualization Tool for Sorting Programming Instruction)를 개발하였다. 뿐만 아니라 VTSPI는 비주얼 프로그래밍에 기반을 둔 소프트웨어 컴포넌트이기 때문에 학생들이 쉽게 프로그래밍할 수 있고, 자신의 프로그램을 이해할 수 있고, 디버깅을 쉽게 할 수 있게 해준다. Data structure and algorithm are primary courses for computer programming instruction. However, now those are not interesting courses for students because the programming instruction methodologies that used these courses are not the proper methodologies for the visual and windows programming. The Sorting programming is the same as other data structures. Therefore, we developed the VTSPI (Visualization Tool for Sorting Programming Instruction) which is a software component to instruct sorting program effectively for solving these problems. As a result, students can code, understand and debug their programs because VTPSI is software components based on visual programming.
