사고 훈련에 의한 우수 집단의 논리적 사고력 및 프로세스 스킬의 발달에 관한 연구
정연태,김범기 한국교원대학교 과학교육연구소 1991 청람과학교육연구논총 Vol.1 No.1
이 연구에서는 우수한 집단의 학생들의 논리적 사고력과 프로세스 스킬을 조사하여 그 특성을 밝히고, 교육에 의하여 어떻게 발달되는가를 밝히는데 있다. 논리적 사고력은 GALT(Group Assessment of Logical Thinking) 검사지를, 프로세스 스킬은 TIPS Ⅱ(Integrated Science Process Skills Test) 검사지를 사용하여 조사하였다. 이 조사는 1989년 12월부터 1990년 1월에 걸쳐서 실시되었으며, 조사대상은 한국 영재아 교육협회에서 실시하는 프로그램에 참가하는 취학전 이동에서부터 중학교 1학년까지 167명이었다. 이들의 논리적 사고력은 4학년 학생이 중학교 1학년 수준에 달하였고, 프로세스 스킬은 3학년이면 중학교 1학년과 같은 수준으로 이 두 가지 능력에서 모두 뛰어났다. 또 이들 중에는 2학년에서부터 형식적 조작기에 도달한 학생이 나타나기 시작하여, 개인의 능력에 따라서 발달단계에 현저한 차이를 보였다. 이 프로그램에 참가자를 1년까지(그룹 A)와 그 이상 (그룹 B)으로 나누어서 조사한 결과, 논리적 사고력과 프로세스 스킬에서 모두 그룹 B 학생들의 득점이 높아, 이 프로그램에 참가기간이 긴 학생들의 득점이 높았다. 그룹 B의 학생들의 논리적 사고력에서는 비례논리, 변수제어 및 조합논리가, 프로세스 스킬에서는 가설설정, 변인통제의 능력이 많이 신장되었다. 형식적 조작기에 도달한 학생은 그룹 B의 학생이 많아 이러한 프로그램을 통하여 논리적 사고력이 향상되고, 앞으로 이와 같이 논리적 사고력을 향상시키는 프로그램에 관한 많은 연구가 요구된다. The purpose of this study was to investigate the development of logical thinking and process skills of gifted children and to examine the effects of the program for gifted children which was conducted by KNAGC(Korean National Association for the Gifted Children). The subjects of this study were 167 children from kindergarten to grade 7 who were participants of the KNAGC program. They were identified as concrete, transitional or formal operational stage using GALT(Group Assessment of Logical Thinking). Their process skills were investigated with the use of TIPS Ⅱ(Integrated Science Process Skills Test). This study indicated that 4th grade children's GALT score is equal to the that of 7th grade students and 3th grade children's TIPS Ⅱ score is equal to that of 7th grade students in Korea. Some of them were in the formal operational stage from the 2nd grade. They were classified into two groups according to the length or time they participated in the KNAGC program. Group A was those who participated less than one year; group B was those who participated one year or longer. The result showed a statistically significant difference between group A and B in both tests. This result indicated that the children's proficiency of logical thinking is positively related to the length of education, this showing the relative advantage for the educated children to reach the formal operational stage through the transition stage from the concrete operational stage. The gifted children of preschool and low grades can reach the formal operational stage within a relatively short period through early training of logical thinking. Group B showed more advanced process skills than group A. This finding also signifies the efficacy of the length of education, which is vital for improving their ability of process skills. The program was effective in improving proportion, control of variables, combination in logical thinking and identifying and stating hypothesis and indentyfying variables in science process skills.
朝鮮總督 寺內正毅의 韓國觀과 植民統治-漸進的 民族同化論과 民族差別 暴壓政策의 이중성-
정연태 한국사연구회 2004 한국사연구 Vol.124 No.-
This paper analyzes why Terauchimasadake(寺內總督), Governor- general of Chosun(朝鮮), maintained the policy of coercive nation discrimination in spite of his self-avowed ruling philosophy of gradual assimilationism during the early 1910s. Terauchi held a historical view that the ancestors of Japan and Korea are identical. At this time, this view was connected with his conception that Chosun was very stagnant and therefore couldn't achieve a national independence. On the basis of this view, he asserted frequently that the imperial Japan could assimilate korea and the two nations, Japan and Korea, could be amalgamated into one. But he didn't have intention to carry out the policy of assimilationism totally in Korea. He judged that the total application of assimilationism to Korea was difficult, because the standard of Korean people was low, their national identification was very strong and their anti-Japan sentiment was not subdued. On the ground of this judgement, Terauchi adopted the policy of gradual assimilationism . However, the problem is that the gradual assimilationism itself was not carried out as a policy, though it was sloganized. Two points came out as the cause. On the one hand, Japan did not possess the power to assimilate Korea. On the other hand, the Korean people's strong sentiment for national identification and against Japanese imperialism deterred the drive of gradual assimilationism. Therefore, Terauchi selected the policy of coercive nation discrimination as the keynote of colonial policy. The policy was based upon the discriminative colonial rule which put its ruling subjects into three categories : the Japanese in Japan, the Japanese in Korea and the Korean. As a result, Terauchi's gendarmerie police system became the means and basis which kept up the policy of coercive nation discrimination.

중국(中國)은 1991년에 새로운 토양계통분류법(土壤系統分類法)을 1차(次) 시안(試案)으로 확정 발표하였다. 본 체계는 미국의 Soil Taxonomy 체계와 비슷한 형태계량적규준(形態計量的規準)(Morpho-metric definition)으로 되어 있고 전산(電算)프로그램화(化)도 가능한 체계로 되어 있다. 분류체계는 목(目)(Order, 토망(土網)), 아목(亞目)(Suborder, 아망(亞網)), 군(群)(Group, 토류(土類)), 아군(亞群)(Subgroup, 아류(亞類)), 속(屬)(Family, 토속(土屬)), 통(統)(Series, 토종(土種))으로 되어 있고, 현재 13개 목망(目網), 33개 아목(亞目), 77개 군(群), 301개 아군(亞群)으로 분류되어 있다. 특징적표층(特徵的表層)은 유기표층(有機表層) 등(等) 8종, 진단표하층(診斷表下層)(차표층(次表層))은 표백층(漂白層) 등(等) 10종, 기타 특징토층(特徵土層)은 석회적표층(石灰的表層) 등(等) 12종, 그리고 암성(岩性) 등(等) 23종의 토양 생성적(生成的) 특징(特徵) 또는 현상(現像)을 분류기준으로 쓰고 있다. 분류상의 특징은 고위도(高緯度)나 고산지대(高山地帶)의 영구동결층(永久凍結層)을 강조하여 아목수준(亞目水準)에서 분류하였고 논토양이나 관개퇴적토(灌漑堆積土), 영양분(營養分)이 심층(深層)까지 집적(集積)된 채전(菜田) 등(等) 인위적(人爲的) 영향(影響)을 크게 받은 토양을 최고차(最高次) 분류단위(分類單位)인 목수준(目水準)에서 독립(獨立)시키고 있을 뿐 아니라 인위적인 교란(攪亂)을 받았으나 아직 단면(斷面)의 발달이 없는 토양을 초육토(初育土)의 아목수준(亞目水準)에서 구분하고 있다.

In order to investigate the effect of WK-101 on the human chromosomes, the frequency of sister chromatid exchange were examined after cultured human peripheral lymphocyte exposed to WK-101 and acetaldehyde. The results obtained were as followings ; 1. The acetaldehyde treated groups showed does-dependent increase of the frequency of sister chromatid exchange. 2. The WK-101 treated groups showed similar frequency of sister chromatid exchange as compared with the control group. 3. The WK-101 and the acetaldehyde treated groups showed markedly increase of the frequency of sister chromatid exchange. In these cases, increase of the frequency of sister chromatid exchange might be due to cytotoxicity by acetaldehyde. From the above results, it is suggested that WK-101 did not show the remarkable effect for the exchange of sister chromatid.
