자료를 표현하기 위해 선택되는 그래프와 그의 특징은 자료 수집의 목적 및 맥락, 그리고 수집된 자료의 유형에 의해 결정되기 때문에 통계적 자료를 표현하는 그래프에 대한 학습을 위해 학생들은 측정과 관련된 맥락에 대한 이해를 필요로 한다. 본 연구에서는 중학교 학생들이 자료와 그래프를 선택하고 해석할 때, 측정과 척도에 근거한 비판적 사고를 통해 맥락적 영역과 통계적 영역 사이의 상호적 전환을 보이고 있는지 살펴보았다. 조사결과, 학생들은 맥락적 영역과 통계적 영역 사이의 상호 전환을 필요로 하는 자료의 측정과 자료를 표현하는 척도와 관련한 비판적 사고가 부족함을 확인하였다. 특히 학생들은 제시된 자료나 그래프의 정보에 대해 의심을 거의 품지 않는 경향을 보였으며, 또한 문항에서 제시한 통계적 조사의 목적과 같은 맥락에 비추어 문제점을 찾아내거나 유연성을 발휘하여 판단하는 능력이 부족하였다.

Performance of a small-capacity solar absorption cooling system was investigated experimentally. Ten sets of evacuative-tube solar-heat collectors and a 5 kW single-stage absorption cooler were combined to produce a hybrid cooling system. The performance of the cooling system was measured using a tim-coil unit installed in a small plastic storage. It was found from the test on a sunny day of May that when the temperature of the hot water supplied from the solar collectors to the generator of the absorption cooler reached $60^{\circ}C$, the absorption cooler started cooling and the cold water temperature measured from the fan-coil unit reached $18^{\circ}C$. The COP, which is defined as the ratio of the cooling power to the total electrical power input was higher than 1.0.

In this paper we emphasize the introduction of ‘incommensurability’ on the teaching and learning the irrational number because we think of the origin of number as ‘ratio’. According to Greek classification of continuity as a ‘never ending’ divisibility, discrete number and continuous magnitude belong to another classes. That is, those components were dealt with respectively in category of arithmetic and that of geometry. But the comparison between magnitudes in terms of their ratios took the opportunity to relate ratios of magnitudes with numerical ratios. And at last Stevin coped with discrete and continuous quantity at the same time, using his instrumental decimal notation. We pay attention to the fact that Stevin constructed his number conception in reflecting the practice of measurement : He substituted ‘subdivision of units’ for ‘divisibility of quantities’. Number was the result of such a reflective abstraction. In other words, number was invented by regulation of measurement. Therefore, we suggest decimal representation from the point of measurement, considering the foregoing historical development of number. From the perspective that the conception of real number originated from measurement of ‘continuum’ and infinite decimals played a significant role in the ‘representation’ of measurement, decimal expression of real number should be introduced through contexts of measurement instead of being introduced as a result of algorithm.

감성이 기억 및 학습과 밀접하게 관련되어 있다는 최근의 연구결과와 학습의 정의적 측면에 관한 교육계의 높은 관심에도 불구하고 학습자의 감성에 기반한 교수방법이나 학습환경에 대한 체계적인 연구가 부족하다. 면대면 강의와 온라인 학습에서 감성의 역할을 이해하고 긍정적 감성을 촉진하기 위한 노력이 점차 증가하고 있으나, 학습자의 감성을 타당하고 신뢰롭게 측정하는 것은 여전히 도전적인 과제로 남아있다. 감성을 고려한 교육을 실천하기 위해서는 학습자의 기억에 의존한 자기보고식 감성측정도구의 제한점을 보완하는 것이 필요하다. 본 연구는 최근 교육학과 인접학문 영역에서 사용되고 있는 감성측정도구를 자기보고, 생리적 신호, 행동적 반응의 측면에서 조사하고 그 도구들이 교수학습 상황에서 어떻게 활용될 수 있는지를 논의하였다. 특히, 실시간으로 학습자의 감성을 편리하게 수집하여 분석할 수 있는 첨단 테크놀로지의 교육적 활용방안을 조사하였다. 이 연구는 향후 실제적인 교수학습 상황에서 감성의 역할을 규명하고 학습자의 감성 변화를 고려한 적응적 학습환경을 설계하는 데 크게 기여할 것이다.

This study examined changes of elementary school students' knowledge and attitudes toward AIDS after AIDS health educational programs were conducted. The experiment was executed from November the 28th, 2001 to February the 6th, 2002. Study examinees were 156 fifth year students of 2 elementary schools located at S City. A preliminary inspection was implemented. The post-examination was conducted by a questionnaire survey 2 weeks and 9 weeks after the program was finished. The measurement instrument was the questionnaire developed by Yun, Hyun Sik(1997) and modified by this researcher. Collected data were analyzed with SPSS program package, $x^2$-test and t-test, Repeated Measure ANOVA. Findings of study are as follows; 1. Hypothesis 1 ; the hypothesis 1 is "The points of AIDS knowledge are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". After the above hypothesis was examined, interactive actions were shown among different periods in both groups (F=267.241, p=.000), so that this hypothesis 1 was approved. 2. Hypothesis 2 ; the hypothesis 2 is "The points of attitudes toward AIDS are different at each moment, before conducting the educational program, 2 weeks after conducting the educational program, and 9 weeks after conducting the educational program". It was closely examined, and the findings are that significant differences between two groups were found, whereas any interactions were not shown between two groups(F=3.753, p=.055), after controlling the attitude scores that showed differences before the education by covariable, and examining the results. so that this hypothesis 2 was rejected. The above study tells that the AIDS health education for elementary school students made their knowledge and attitudes change significantly, but the education was not effective for changing students' attitudes. Elementary school students need more systematic and continual AIDS health education.

The purpose of this study is to investigate the effects of educational programs on the needs and satisfaction level of nursing activities related with patients receiving anti-cancer chemotherapy. The subjects, 85 cancer patients who were admitted at St. Mary's hospital, who had taken chemotherapy between January and March, 2001 were selected for the study. Of the subjects educational program was applied to 43 patients and the other 42 patients remained and the control group. Educational booklets developed by investigators were validated by a group of judges consisted of nursing professors, physicians and head nurses. Cronbach's $\alpha$ for measurement tools used in this study were 0.96 - 0.98. The results of the study were as follows: 1. Satisfaction scores for received nursing activities m the experiment group were higher than that in the control group. 2. Needs scores for nursing in the experimental group showed no significant differences compared to the control group. The two groups showed different satisfaction levels in different categories of nursing: physical. educational. therapeutic and socio-psychological, in which the therapeutic category scored the highest. 3. Due to the general characteristics. there were no variables to affect the degree of nursing need regarding the two groups. However, in satisfaction level of nursing services, there was a contrary phenomenon between the two group relating to education level (p=0.03). Patients with higher educational levels tend to be more satisfactory. The results strongly indicated that educational program is effective in increasing the satisfaction of patients receiving anti-cancer chemotherapy.

The aim of this study was to analyze the research trends in articles published in the Korean Journal of Medical Education (KJME) and Korean Medical Education Review (KMER) using keyword network analysis. The analyses included 507 papers from 2010 to 2019 published in KJME and KMER. First, keyword frequency analysis showed that the research topics that appeared in both journals were "medical student," "curriculum," "clinical clerkship," and "undergraduate medical education." Second, centrality analysis of a network map of the keywords identified "curriculum" and "medical student" as highly important research topics in both journals. Third, a cluster analysis of 20 core keywords in KMER identified research clusters related to academic motivation, achievement, educational measurement, medical competence, and clinical practice (centered on "learning," while in KJME, clusters were related to educational method and program evaluation, medical competence, and clinical practice (centered on "teaching"). In conclusion, future medical education research needs to expand to encompass other research areas, such as educational methods, student evaluations, the educational environment, student counseling, and curriculum.
