Background Endoscopic resection of the prostate has conferred considerable advantages on patients requiring prostatic surgery. Prostatectomy is probably the most common major urologic operation performed in most hospitals. However, because the patients are elderly and often have a concurrent respiratory or cardiovascular disease, a small but significant mortality and morbidity still exist. This study was performed to evaluate the factors influencing blood loss during transurethral prostatic surgery. Methods All prostatectomies were audited prospectively, recording the pre-and post-operative hemoglobin concentrations, blood transfusions and the variable factors influencing blood loss. The initial statistical test used for the correlations with blood loss was the primary regression equation followed by the Kruskal-Wallis test. Results The peri-operative blood loss, as assessed by various indicators was equivalent to a decrease in humoglobin concentration of 1.2g/㎗. The weight of the resected prostatic tissue was one of the most important factors measured in determining blood loss. The resection time also influenced the blood loss. Other factors did not influence blood loss. The overall transfusion rate was 2% of all patient. Conclusions The cause of blood loss associated with transurethral resection of prostate(TURP) is multifactoral and it is impossible to measure the effect of a single factor while controlling all the others. We suggest that the weight of the resected prostatic tissue is clearly one of the most important factors and that the assessment of this factor helps in anticipating blood loss. Epidural anesthesia is associated with less blood but its advantage is overshadowed in practice by the weight of the resected tissue.

일제강점기 중등학생의 교사배척 동맹휴학을 통해 본 관행적 민족차별

정연태 연세대학교 국학연구원 2019 동방학지 Vol.189 No.-

The unified strikes of Korean secondary students against problematic teachers during the Japanese colonial rule resulted from the expression of students' consciousness of human rights, rights, and ethnicity. Customary ethnic discrimination—one of the reasons for rejecting problematic teachers in student strikes—was led by Japanese teachers. Western teachers and a very small number of Korean teachers also participated in it. There were three methods of customary ethnic discrimination: unilaterally insulting Koreans, despising Korea (and Koreans) through comparison between Korea and Japan, or discriminating between Korean students and Japanese students. This discrimination tended to be accompanied by teachers’ dogma, despotism, and violence. Three logics underlay the words and actions of teachers who practiced customary ethnic discrimination: the theory of a savage race based on the dichotomy of civilization vs. barbarism, a theory of ethnicity that emphasized the defects and negativity of Koreans, and the theory of people of a ruined nation, which recognized the current state of the perished nation and reproved the people themselves. Two factors contributed to the continuing background of customary ethnic discrimination. One was the racist and coercive educational and administrative structure, and the other was western orientalism and images of Japanese contempt toward Korea. 일제강점기 중등학생의 교사배척 동맹휴학은 학생들의 인권의식, 권리의식, 민족의식이 표출된 결과였다. 교사배척 동맹휴학의 발생률은 공립학교보다 사립학교에서, 실업계 학교보다 인문계 학교에서 더 높았다. 사립학교의 교사배척 동맹휴학에서는 학습권 보장 요구가 가장 빈번하게 제기됐으나 관행적 민족차별 반대의 목소리는 약한 편이었다. 반면 공립학교의 그것에서는 전제적·독선적·억압적·폭력적 교육과 관행적 민족차별에 대한 반발이 사립학교에 비해 강하게 표출됐다. 동맹휴학에서 교사배척의 주된 사유 중 하나인 관행적 민족차별은 일본인교사가 주도했다. 그러나 서양인교사나 극소수 한국인교사들도 이에 참가했다. 이는 민족차별 문제가 한일 간의 단순한 민족문제 이상이라는 점을 보여준다. 관행적 민족차별의 방식은 3가지였다. 한국민족과 한국인을 일방적으로 모욕하거나, 한일 비교를 통해 한국민족과 한국인을 비하하거나, 한일 학생을 차별 대우하는 방식이다. 이러한 민족차별에는 교사의 전제·독선·억압·폭력이 수반되는 경향을 보였다. 관행적 민족차별을 자행하는 교사들의 언행을 관통하는 논리는 세 가지였다. 문명 대 야만의 이분법에 기초한 야만인(종)론, 한국인의 온갖 결함과 부정성을 드러내기 위한 민족성론, 망국의 현실을 인정하고 자책케 하는 망국민론이었다. 이러한 관행적 민족차별이 지속된 배경에는 두 가지 요인이 작용했다. 하나는 민족차별적이고 강압적인 교육·행정 구조였다. 다른 하나는 근대일본의 한국 멸시관과 서구의 오리엔탈리즘이었다.

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.

정연태,유기연,이희수 한국조직공학과 재생의학회 2015 조직공학과 재생의학 Vol.12 No.4

Human embryonic stem cells are multipotent cells. In this study, We observed osteogenesis of human embryonic stem cell derived mesenchymal stem cells. mbryonic body formation method was used to derive mesenchymal stem cells from human embryonic stem cells. Embryonic stem cell derived mesenchymal stem cells were immunostained for CD 73 to make characterization of mesencymal stem cells. Osteogenesis of CD 73 positive mesencymal stem cells with media included ascorbic acid, dexamethasone and glycerophosphate was induced. After 10 days culture with osteogenesis media, the cells were immunostained with type I collagen, osteocalcin and Runx-2. After 21 days culture with osteogenesis media, the cells were stained with alizarin red to observe bone nodule formation. Mesenchymal stem cells were derived from human embryonic stem cells by embryonic body method. After these cells were cultured with osteogenesis media, the cells were differentiated into osteoblast and showed bone nodule formation.
