정연주(Jeong, Yeon-Joo),김병인(Kim, Byoung-In) 한국인물사연구회 2014 한국인물사연구 Vol.22 No.-

This study aims to address argumentative issues and aspects of Choi, Ho-Won(崔灝元)’s complementary theory(裨補說) in the reign of King Sung-Jong(成宗). After examining Choi, Ho-Won’s life and conception, this research analyzes the debates when Choi, Ho- Won insists the conception which refers to Doseon(道詵)’s complementary theory in sixteenth year of King Sung-Jong. Based on that, following issues can be suggested: There was an assertion that a position that given to Choi, Ho-Won, Byungjochamji(兵曹參知) is not proper, and that he should be punished because of his theoretical notion. At least two things can be drawn out of above discussion. First, King Sung-Jong is the person who is willing to keep Jeong-hak(正學) with the exclusion of other theories. Second, there were certain differences between the Confucian scholars including Choi, Ho-Won and King Sung-Jong in the light of their perception about natural disaster(災變) and, the way of making the ruling method on the public according to that. Additionally, the government official have also negative point of view on Doseon’s complementary theory. Docham’s(圖讖) idea, a foundation of Doseon’s theory, was likewise denied, due to changing theory on Feng-shui(風水) in early Chosun Dynasty, and a political notion to promote Confucian ideas, which was a major ideological stream in the reign of King Sung-Jong.

이 연구는 중학교 8학년 과학 '지구의 역사와 지각 변동' 단원에서 ICT 활용 수업 과정안을 개발ㆍ적용하여 ICT 활용 수업이 학생의 과학 탐구 능력과 과학에 관련된 정의적 특성에 미치는 효과를 알아보는 데 그 목적이 있다. 이 연구를 위해 충청남도에 소재한 D중학교 2학년 2개 학급을 선정하고 교수-학습 방법을 달리하여 약 6주간 수업하였다. 1개 학급은 실험집단으로 ICT수업 과정 안을 개발하여 ICT를 활용한 수업을 실시하였으며, 1개 학급은 통제집단으로 교과서 위주의 전통적 방법으로 수업 하였다. 학습을 하기 1주일 전에 두 집단을 대상으로 과학 탐구 능력과 과학에 관련된 정의적 특성에 대한 사전 검사를 실시하였으며, 수업이 끝난 뒤에 사후 검사를 실시하였다. 그 결과, ICT를 활용한 실험집단과 전통적 학습을 실시한 통제집단의 과학 탐구 능력 검사에서는 실험 집단에서 유의미한 차이가 나타났다. 또한, 과학에 관련된 정의적 특성에 대한 검사에서 실험집단에서 통계적으로 유의미한 차이가 나타나지는 않았지만, 3개의 과학에 관련된 특성 범위 중에서 흥미 범위에서는 통계적으로 유의미한 차이가 나타났다. 이는 ICT 활용 수업이 학생들의 과학에 관련된 정의적 특성에도 긍정적인 효과가 있음을 시사하는 것이다. The effects of learning using Information Communication Technology(ICT) on the students' scientific inquiry ability and science-related affective characteristics were analyzed in Earth History and Crust Movement units of science textbook for eighth graders. For this study, two classes of middle school second students in Chung-nam were selected and taught for six week under different teaching methods. One class is the test class taught with ICT applied teaching materials and the other class is the control class instructed by a conventional method. One week before the experiment, both classes were given tests on scientific inquiry ability and science-related affective characteristics, and they were tested again after the experiment. The results of scientific inquiry test showed statistically meaningful differences in the experimental class and the control class. The experimental class showed statistically meaningful difference in scientific inquiry test. Science-related affective characteristics test showed no statistically meaningful difference in the experimental class. Among three scientific science-related affective characteristics, especially the one fields of interests showed statistically meaningful differences which suggest that learning using ICT has a positive effect on the expanding of students' science-related affective characteristics.

Paper has been an essential part of our civilization for at least two thousand years and we can get various functional paper given by the treatment of coating, laminating, blending and addition of chemicals. Above all, wet strength paper is an important group of other grade paper. Certain paper require a wet strength in order to maintain their properties under wet or humidity conditions. For the purpose of improving the wet strength properties of paper, cellulose fiber was modified by the process of carbamoylethylation and carboxy- methylation. We have the carbamoylethylation of cellulose fiber reacted with acryl- amide in alkali catalyst and carboxymethylation of cellulose fiber reacted with mono- chloroacetic acid in alkali catalyst. The N-chlorocarbamoylethylated sheet and combined sheet of carboxymethylated and carbamoylethylated cellulose fiber more effect than untreated sheet in dry strength. As for folding endurance, the combination of carboxymethylated cellulose fiber and carbamoylethylated cellulose fiber sheet were more effective than other modified fibers. The combination of carboxymethylated cellulose fiber and carbamoylethylated cellulose fiber sheet has some effect on wet tensile strength, but this sheet it less effective than N-chlorocarbamoylethylated sheet.

Carboxymethylation of recycled pulp was investigated. For both recycled pulp and dissolving pulp was carboxymethylated by the organic solvent method and tested some industrial analyses, water solubles content, low concentration of NaCl solution solubles and acid hydrolysis. The water solubles content depend on degree of substitution, and low concentration of NaCl did not affected solubilities of the CMC. Prehydrolysis of CM groups prior to reaction with L­cystein, we can obtain the residual unsubstitued anhydroglucose(USAG). The lower amount of USAG in recycled pulp, compared to theorecal data, was suggested that the recycled pulp should obtain the more CM group in the same conditions.
