  • This study was designed for middle school students in Su-Won City to find out their level of hope in environmental education and who had not been introduced to environmental skills and knowledge as a separate subject in their school curriculum. Additionally, the result of the study was expected to provide basic environmental education material to teachers who are on the front line in our environmental education efforts. The mother used to be very influential on her children's thinking and behavior to a large degree. Acknowledging these facts, students and their mothers were chosen for this study The questionnaire from each of the two groups were compared and studied. The questionnaire, comprised of 23 questions, was completed during the period of time from March 6 through March 11, 2000. The schools that participated in the study were 5 junior high schools in Su-Won City and the participants were students and their mothers. The questionnaires were given to 450 students and their mothers to be completed and returned. A total of 379 student questionnaires and 323 mother questionnaires were received for examination. The results of questionnaire were analyzed by using SPSS/PC 8.0 software program with Frequencies Analysis, Mean Analysis, Reliability Analysis, Correlation Analysis, Paired Samples T-test, and $\chi$$^2$-test. The questionnaires generated the following results. The reliability coefficient was 0.847 from the students and 0.895 from the mothers. The level of interest in an environmental education curriculum was 24.3% from students and 86.0% from mothers. Interestingly, the gender difference of level of interest in an environmental education curriculum was 25.7% from male and 23.1% from female. The difference in the environmental function levels between female and male students was statistically significant(t=-4.109, p<0.001). For mathematical skills in environmental functions, the students and mothers thought trash, air pollution, and lack of forest were problems however they showed inactive support and unreasonable attitudes toward the problems that they themselves pointed to for solving the problems. Under the environmental problems solving issue, the significance between two groups was 0.014(P<0.001) and the result dictates there was no correlation. The t-test showed no difference in environmental knowledge level between student genders. The knowledge level between students and mothers was related each other. The Paired Sample t-test between students versus mothers on environmental skills and knowledge was 0.000*(*P<0.001) and it showed there was correlation between the two groups. With this study, educating mothers should be noticed as a great priority in environmental education that will lead to a more positive environmental outlook from our students.

  • 본 연구는 급변하는 사회 변화의 흐름 속에서 수학교육을 평생교육적 관점에서 논의해야 할 필요성이 제기됨에 따라 현재 성인들이 필요로 하는 것이 무엇인지 파악하기 위해 성인들의 수학에 대한 인식을 탐구하는 연구이다. 이를 위해 "연구 참여자들의 학교 수학에 대한 경험은 어떠한가? 정규학교 교육 이후 연구 참여자들은 수학을 무엇이라고 인식하고 있는가?" 라는 연구 문제 하에 다양한 사회문화적 배경을 지닌 성인 10명을 인터뷰하고 내러티브 탐구 방법으로 분석하였다. 결과적으로 연구 참여자들은 학교 수학을 단순한 문제 풀이로 받아들이는 경향이 있었고, 수학적 지식의 유용성을 알지 못했을 때는 수학 학습 과정에서 수학에 대한 좌절이 나타날 수밖에 없었다. 이러한 교육 경험을 지닌 연구 참여자들이 정규 교육 과정 이후에는 수학을 '일상에 내재화되어 있는 기초 연산 및 기본 교양, 문제 해결에 유용하며 논리적인 사고 방식, 현상을 파악하고 표현하기에 유용한 도구'로 인식하고 있었다. 즉, 성인들은 학교 교육을 내재화시켜 수학이 자신의 삶에서 어떤 역할을 하는지 명확하게 파악하고 있었고, 자신의 삶에서 수학을 효율적으로 사용하고 있었다. 이에 따라 학교 교육과 성인 교육을 연결성 상에 놓고 바라볼 필요성과, 성인에게 필요한 수학 능력을 수학 소양으로 개념화할 필요성이 제기되었다.

  • 지식 기반 사회를 맞이하여 컴퓨터 교육에 대한 관심이 점점 높아가고 있다. 컴퓨터 교육에서 프로그래밍 교육은 매우 중요하다. 그러나, 기존의 프로그래밍 교육은 프로그래밍 언어의 문법에 대한 기계적 암기나 사용법을 익히는 것에 치중해 왔다. 그래서 그 프로그램이 갖는 의미와 어떻게 다른 방법으로 구현될 수 있는지 등의 논리적인 사고를 키우는데 적합하지 못했다. 이런 프로그래밍 교육의 현실을 개선하여 정보 소양을 기르고 문제 해결 능력의 함양이라는 프로그래밍 교육의 목표를 달성하기 위해서는 프로그래밍 교육의 접근 방법에 대한 개선이 필수적이다. 따라서 본 논문에서는 프로그래밍 학습에 대한 새로운 접근법으로 프로그래밍 언어의 기초가 되는 C언어를 통해 프로그래밍에 대한 기본적인 통찰력과 테크닉을 기를 수 있도록 수학 프로그래밍 소스들을 구현하고자 한다. 이는 프로그래밍 학습에 대한 흥미와 관심이 증대되며 프로그래밍에 대한 경험을 쌓는 과정에서 문제 해결력 및 논리적 사고력의 향상과 프로그래밍에 대한 감각을 키워주는 좋은 경험이 될 것이다.

  • Although ‘to understand mathematics’ is an important educational purpose, most student do not have a relational understanding of the basic concept of mathematics but have a instrumental understanding. This paper will investigate the possibility of using computers for enhancing relational understanding. In the ‘Qualitative case study’, three students who are in the first grade at E-High school took part in 7 activities during four weeks, and were later interviewed and engaged in informal discussion and were observed. This is the result of this study. 1. The three students were passive participants in mathematics problem solving situation at school. Therefore, student B just applied formulas which she had memorized, and student C would forgot the formulas occasionally. These common students needed to participate actively in doing mathematics. 2. The activities utilized two software healing with connection between graphs and function, giving the students the opportunity to plan, practice, and test by themselves. As a result, they understood the mathematical formulas and rules more deeply through their own trial and error, and then they gained thinking abilities necessary for doing mathematics. In addition, the activities boosted their confidence. 3. The understanding type of students was slightly different. Student A who received a high score, understood the most relationally, but student B who received a very high score, understood instrumentally and so couldn't app1y her knowledge to solving problems related to function concept. Student C who received a middle score lacked knowledge of mathematics but thought more creatively. The result is that students need an opportunity to think rotationally regardless of score. Therefore, this study concludes that using computer software will provide a positive effect for relational understanding in loaming function concept.

  • As a result of the enormous amount of information that has been collected with E. coli over the past half century (e.g. genome sequence, mutant phenotypes, metabolic and regulatory networks, etc.), we now have detailed knowledge about gene regulation, protein activity, several hundred enzyme reactions, metabolic pathways, macromolecular machines, and regulatory interactions for this model organism. However, understanding how all these processes interact to form a living cell will require further characterization, quantification, data integration, and mathematical modeling, systems biology. No organism can rival E. coli with respect to the amount of available basic information and experimental tractability for the technologies needed for this undertaking. A focused, systematic effort to understand the E. coli cell will accelerate the development of new post-genomic technologies, including both experimental and computational tools. It will also lead to new technologies that will be applicable to other organisms, from microbes to plants, animals, and humans. E. coli is not only the best studied free-living model organism, but is also an extensively used microbe for industrial applications, especially for the production of small molecules of interest. It is an excellent representative of Gram-negative commensal bacteria. E. coli may represent a perfect model organism for systems biology that is aimed at elucidating both its free-living and commensal life-styles, which should open the door to whole-cell modeling and simulation.

  • The mathematical processing (unfolding) of pulse height spectra from a scintillation detector helps to calculate the photon fluence rate energy distribution in a measured photon field. The data processing is based on the knowledge of detection system response function and directional dependence respectively. The experimental results of the photon fields measurements in the vicinity of the spent fuel temporary storage and inside the storage hall are presented. The containers Castor 440 are used for temporary storing of the burnt up fuel assemblies in the Czech nuclear power plant Dukovany. A set of periodical measurements was performed in order to get basic information on the time dependence of the photon fields spatial distributions and spectral characteristics in the temporary storage hall and its vicinity. The photon fields were measured by the scintillation system. The obtained photon fields spatial distributions and spectral characteristics present the information on the radiation hazard in the storage.

  • Innovations significantly affect the efficiency of the socioeconomic systems of the regions, acting as a system-forming element of their development. Modern models of economic development also consider innovation activity, intellectual potential, knowledge as the basic factors for stimulating the economic growth of the region. The purpose of the study is to develop methodological foundations for evaluating the effectiveness of a regional innovation system based on a multidimensional analysis of its effects. To further study the effectiveness of RIS, we have used one of the methods of multidimensional statistical analysis - canonical analysis. The next approach allows adding another important requirement to the methodological provision of evaluation of the level of innovation development of industries and regions, namely - the time factor, the formalization of which is realized in autoregressive dynamic economic and mathematical models and can be used in our research. Multidimensional Statistical Analysis for RIS effectiveness estimation was used to model RIS by typological regression. Based on it, multiple regression models were built in groups of regions with low and relatively high innovation potential. To solve the methodological problem of RIS research, we can also use the approach to the system as a "box" with inputs and outputs.
