최병순,전경수 전남도립대학교 2000 전남도립대학교 논문집 Vol.3 No.-
Dye wastewater was treated with an electrolysis process. The electrochemical technology using C/C, Fe/Fe, Al/ Al electrodes was investigated. In this study, electrode material, electrode concentration, electrode distance, current density, and pH value were found to have significant effect on COD and color removal efficiency in electrolysis process. After electrolysis for 60min with AV Al, COD removal efficiency was 57% and color removal efficiency was 100%, respectively. COD removal efficiency with electrode distance was 62% in 3cm after electrolysis for one hour. Removal efficiency of color was 100%. It was explained by the activation of electrooxidation and electrocogaulation. The removal efficiency of COD with current density seemed to be 55% in 40mN cm² after one hour reaction and color removal efficiency was 100%. The removal efficiency of COD with electrode concentration was 62% in NaCl 4000ppm after one hour reaction and color removal efficiency was 100%. The highest removal efficiency of COD and color with variation of pH was pH 5.0. The removal efficiency of T-N, NH₄⁺-N, color was 38%, 82%, 90% after 40min reaction. The optimal conditions of the electrooxidation process to treat the dye wastewater in this study were as follows current density(40mA/cm2 ), electrode distance(3.0cm), pH value(5.0) and Al/ Al electrode.

In order to develop effective environmental-friendly seed treatments for Bakanae disease caused by Gibberella fujikuroi in rice seedlings, we investigated the effects of dry heat, chemical and warm water treatments on seed germination, seedling growth, and infection rate of Bakanae disease in contaminated rice seeds, and tried to find out the maximum high temperature limits and post treatment conditioning for rice seeds. The results showed that germination and height of seedlings as affected by warm water and chemical treatments were similar, and disinfectant efficiency was good in combined treatment with warm water and chemical treatments. Although warm water and chemical treatments did not show serious infection rates, some dry heat treatments showed varying infection rates. These varying infiection rates could be significantly reduced by increasing the maximum temperature of dry heat treatment even though seed germination was also decreased by high dry heat temperatures. Therefore, between 80℃ to 85℃ of maximum and 3 days of post conditioning treatments of dry heat treatment should be applied for disinfection of rice seed for Bakanae disease. These results indicated that dry heat treatment may be effectively used as one of the major environmental- friendly seed treatments.

최병순,김범기,강성주,신재섭,인미영,신애경,김영신,진정미,Choi, Byung-Soon,Kim, Beom-Ki,Kang, Seong-Joo,Shin, Jae-Sup,In, Mi-Young,Shin, Ae-Kyung,Kim, Young-Shin,Jin, Jeong-Mi 대한화학회 2004 대한화학회지 Vol.48 No.5
이 연구는 다양한 창의적 교수 전략을 이용하여 학생들의 창의력 계발을 위한 프로그램을 개발, 적용하여 그 효과를 검증하고, 프로그램에 대한 교사와 학생의 인식을 조사 분석하여 향후 확대 실시를 위한 개선점을 모색하는데 목적을 두었다. 중학교 7학년 과학과 내용 중 일부를 다양한 교수 전략을 이용하여 창의력 프로그램으로 개발하고, 이를 3학급 93명의 학생들을 대상으로 약 3개월 동안 처치하였다. 연구 결과, 실험집단 학생들의 창의력이 전통적인 과학 수업을 받은 학생에 비하여 크게 향상 되었다. 특히 창의력 하위 요소 중 개방성 요소에서 큰 향상이 있었다. 과학 성적에 따른 창의력 변화를 분석한 결과, 과학 성적이 높을수록 창의력에 큰 향상이 있었다. 창의력 프로그램과 그 적용에 대한 교사와 학생의 인식을 조사한 결과, 모든 교사와 대다수의 학생들이 긍정적인 인식을 나타내어, 학교 현장에 적용 가능성이 높음을 확인할 수 있었다. 프로그램 적용상의 문제점을 분석한 결과, 수업시간의 부족, 학급당 인원의 과다, 학생들의 적극적 참여 결여 등의 문제점이 드러났다. 따라서 창의력 계발을 위한 프로그램에 대한 지속적인 연구와 함께 이러한 문제점들에 대한 해결 방안이 사전에 모색되어야 할 것이다. The purposes of this study were to find out the effectiveness of instructional program developed utilizing various strategies to foster the students creativity in science and to analyze the recognition of the students as well as the science teachers on this program for the improvement of the program. Instructional program was consisted of student's worksheet and teacher guidebook. This program was applied to 93 7th grade students for three months. Result of this study showed that the students in experimental group got higher scores than those in the control group, which implied that creativity of the students could be promoted through specially designed program. Analysis of the change of creativity of the students by science achievement showed that the degree of promotion of creativity was higher as the achievement of the students becomes higher. Recognition on this program of the students and teachers who participated in this project revealed positive in that this program was different from the instructional program they have used and that this program would make the students eager to learn and explore the phenomena they faced. Students and teachers also indicated that shortage of instructional time, too many students in class, passive attitude of the students in class discussion, and so on as the problem they have to solve in running the program.

통합주제를 중심으로 한 중학교 수준의 통합과학 내용 구성 방안
최병순,최미화 한국과학교육학회 1999 한국과학교육학회지 Vol.19 No.2
이 연구에서는 자연계에 폭넓게 적용되는 기본 개념들을 몇 가지로 단순화시키고, 이것을 통합주제라고 정의하였다. 이것은 자연계를 관통하는 포괄적 개념 혹은 통합적 시각이라 할 수 있다. 관련 문헌을 분석하여 계(系), 상호작용, 조화와 균형, 구조와 기능, 그리고 순환의 다섯 가지 개념을 통합주제로 설정하고, 각 통합주제의 성격을 규명하였다. 그리고 설정된 통합주제의 성격에 부합하는 내용을 구성하여 각 영역별로 학습 주제와 학습 목표를 진술하였다. 제시된 통합과학 내용 구성은 그 형태에 있어서 간학문적 통합, 혹은 다학문적 통합이라 할 수 있으며, 현행 중학과학보다 통합의 심도가 깊다. 그리고 통합주제의 성격에 우선적으로 초점을 맞춰 구성한 것으로 기존의 4영역 안배 원칙에서 벗어났다. 이와 같은 통합과학 교육과정의 내용 구성 방안은 현재 우리나라의 과학 교육과정에 새로운 관점을 제시하는 의미가 있다. A value can be placed on the integrated science curriculum in terms of producing an insight into solving the routine problem. From such a point of view, the comprehensive concepts which explain the extensive natural phenomena were defined as the integrated themes in this study, and the contents of the integrated science curriculum were developed, as the understanding of the contents focused on the integrated theme enables us to be productive and have an insight. Through analyzing teaching materials, programs and curriculums in relation to the integrated science, five concepts of system, interaction, harmony and balance, structure and function, and circulation were established as the integrated themes, and the nature of each integrated theme was examined. Next, in accordance with the integrated theme, the content of the integrated science curriculum, which are deeper in aspect of the integration level than that of the current science of middle school, were developed. The content of the integrated science curriculum which was proposed in this study is of great significance, in that they provide new perspectives related to our current science curriculum.

동질모둠이 수행한 과학탐구실험에서 실험 진행에 따른 상호작용의 변화와 특성
최병순,성숙경 한국과학교육학회 2008 한국과학교육학회지 Vol.28 No.1
The purpose of this study was to understand the factors affecting interactions as well as the students' learning process in small group activities. For this purpose, the changes and characteristics of students' interactions in scientific inquiry experiments were analyzed. This study focused on 2 homogeneous small groups of eighth graders. Students were involved in 13 inquiry experiments for one year and students' interactions in each experiments were observed and recorded using video/audio and the data recorded were transcribed. The analysis of data was based on the method of making a note by looking on and listening to the data repeatedly. Changes in the interactions of the two homogeneous groups differ remarkably. In small group A, owing to the conflicts of students' emotions, learning through social interactions became to be impossible. On the other hand, the interactions in small group B became more active. It seems that this changes are affected largely by the existence of peers who are able to mediate different opinions or feelings among group members. In general, middle school students were poor at receiving peers' opinion, cared a lot about writing reports. The less able students tended to be placed at a disadvantageous position in experiment lessons emphasizing social interactions. Four factors that affected the change of interactions were identified: Is the aim of experiments the understanding or completion of report? Is there any attitude towards peers' suggestions? Is there a disposition to care about peers? Is there any peer to mediate on peers' opinions or feelings? Educational implications of the progression of activities emphasizing interactions and the organization of grouping were drawn.

중학교 과학과 교육과정 및 그 운영진단Ⅰ : 교육과정 목표 및 목표도달도
최병순,권재술,허명 한국과학교육학회 1987 한국과학교육학회지 Vol.7 No.1
To figure out the present status of Korean middle school science curriculum in the national level is not an easy job, especially in the restricted condition such as this research project. Therefore, to achieve a meaningful result, the case study type of research was adopted. In the study five middle schools(2 boy's and 3 girl's) were selected and examined intensively. In this study, two major works were done. One was the analysis of the present middle school science curriculum and the other was to examine the current status of the administration of the curriculum in schools. This first study focused on the evaluation of the current Curriculum. According to the result, the objectives stated in the teachers guide and implied by the testbook were heavily concentrated on the knowledge level in Boom's taxonomy. Achievement on the objectives which were selected as important were very low. The average pass rate for the selected objectives was less than 50% of the students. This means the content level of the present science curriculum is not appropriate. The study suggested that the present middle school science curriculum should be revised and the content should be replaced with easier topics to match the students cognitive level. The study also suggested further studies to measure the cognitive level of Korean students in national scale.
