세계적으로 지구온난화를 동반한 기후변화로 인해 자연재난이 빈번하게 발생하고 있다. 재해의 발생 유형 중 집중호우와 태풍으로 인한 수문학적 재해가 대부분을 차지하고 있다. 이와 같이 홍수로 인해 발생하는 피해는 강우의 특성과 지역적 특성에 따라 피해의 규모와 범위가 달라진다. 따라서 이러한 이질적인 홍수피해로부터 재산과 인명을 보호하기 위해서는 위해성(Hazard), 노출성(Exposure), 취약성(Vulnerability)을 고려하여 지역 특성에 맞는 홍수방어계획을 수립해야한다. 본 연구에서는 전국 228개 행정구역을 대상으로 과거에 실제로 발생하였던 홍수피해 사례 조사를 통해 지역별 홍수피해 특성을 파악하여 지역 특성을 고려한 홍수피해 강우기준을 제시하고자 하였다. 이를 위해서 재해연보 보고서에 기재되어 있는 과거 홍수피해 기간과 홍수피해액을 수집하였고, 홍수피해 기간동안의 강우량과 뉴스 기사를 수집하여 뉴스 기사에서 언급되었던 홍수피해 현상 정보를 수집하였다. 수집된 홍수피해 정보를 통해 지역별 노출성과 취약성이 반영된 현상기반 강우등급을 제시하였으며, 이와 함께 지역별 강우특성을 나타내며 위해성을 내포하고 있는 확률강우량과의 합성을 통해 위해성, 노출성, 취약성을 고려한 지역별 홍수피해 강우기준을 제시하였다. 대부분 홍수피해에 관한 정보를 재해연보 보고서를 활용하여 수집하지만 홍수피해 현상에 대한 정보를 포함하고 있지 않기 때문에 지역별로 홍수피해로부터 발생하는 홍수피해 유형에 대해 파악하기에는 한계가 있다. 따라서 본 연구에서는 과거 홍수피해가 발생했던 기간에 대해 뉴스 기사를 수집하여 홍수피해 현상 정보를 수집하였고, 수집된 홍수피해 현상 정보를 텍스트 마이닝(Text Mining) 기법을 적용하여 홍수피해 현상 키워드 빈도분석을 통해 어떠한 홍수피해 유형에 취약한지 파악하였다.

The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.

This study aims to explore the differences between Korean and United States college students regarding their degree of religiosity, interest in, understanding and acceptance of evolution, and the effects of their interaction on these variables. A total of one thousand and fifteen Korean and US biology majors and non-majors college students participated in this study and a sub sample of 516 students were randomly selected for statistical tests. The results illustrated that Korean college students harbored significantly lower degrees of religiosity and interest in evolution but significantly higher degrees of knowledge and acceptance of evolution than US college students. The path analysis uncovered that the knowledge of and interest in evolution played a mediating role between religiosity and acceptance of evolution. Korean college students' interest in evolution was less correlated to other variables than US college students' interest. The acceptance of evolution was less predicted by knowledge of evolution in the Korean biology major sample than in the US biology major sample. The acceptance of evolution was predicted more by religiosity in the Korean non-major sample than in US non-major sample. This study suggests that future Korean science curriculum for evolution needs to enhance the degree of students' interest in evolution. In addition, future Korean science curriculum needs an instructional strategy in developing students' ability to make scientific decisions, such as the acceptance of evolution, without interference from their personal religious belief.

The Natural Science High School is specialized in vocational education or training related to natural sciences such as biology or chemistry. Therefore, natural science high school students are expected to possess a high level of science learning motivation. This study aims to explore natural science high school students' level and structure of science learning motivation by comparing students in general high school. One hundred ninety three students from a natural science high school and 208 from a general high school participated in this study. We administered a questionnaire that consisted of seven science motivation components: 1) career motivation; 2) science grade motivation; 3) understanding the relevance of scientific knowledge; 4) need for learning science; 5) self-determination; 6) self-efficacy; and 7) attitudes toward science class. We employed independent t-test, path analysis, bivariate correlation, and stepwise multiple-regression for the statistical analyses. Our findings illustrated that the natural science high school students' levels on all seven variables were significantly lower than the general high school students.' The path analysis illustrated that career motivation and science grade motivation had relatively stronger influence on self-determination and self-efficacy in the natural science high school student sample than in the general high student sample. The explanatory powers of four independent variables (career motivation, science grade motivation, understanding the relevance of scientific knowledge, and need for learning science) predicting self-determination and self-efficacy were 30% higher in the natural science high school student sample than in the general science high student sample. These results suggested that natural science high school students' science learning motivation may be easier to change by extrinsic motivations such as career and science grade motivation.

In this study, the relationship between students' out-of-school science experience and their view on the nature of science was investigated. The participants were 267 sixth graders, 281 eighth graders, and 307 tenth graders from schools in Seoul. A test of views on the nature of science which consists of five items concerning the purpose of science, the definition of scientific theory, the nature of scientific model, the tentativeness of scientific theory, and the origin of scientific theory was administered. Students' out-of-school science experiences were measured with a subscale of the modified Science Experience Survey consisting of seven items. The results indicated that no statistically significant relationship was found between students' out-of-school science experience and their view on the nature of science in sixth graders. In eighth graders, high level students in terms of out-of-school science experiences were found to possess more contemporarily epistemological view in the item concerning the nature of scientific model but more falsificationist view in the item concerning the tentativeness of scientific theory. High level tenth graders in terms of out-of-school science experiences exhibited more epistemologically sophisticated understandings of the nature of science than their counterparts in the items concerning the purpose of science, the definition of scientific theory, and the nature of scientific model.

The goal of this study is to examine the Integrated Science and Science Laboratory Experiments of the 2015 revised curriculum applied since 2018, and to explore ways to improve these two subjects in preparation for the 2022 revised curriculum. A survey was conducted by randomly sampling high schools across the country, with a total of 192 science teachers participating. In addition, 12 high school science teachers were selected as focus group, and in-depth interviews were conducted to investigate ways to restructure common science courses for the next curriculum. Main research results include that most schools were operated in 6~8 units for Integrated Science, and the teachers in charge of Integrated Science per class averaged 2~3 over the three years. For Science Laboratory Experiments, it has operated for a total of two semesters, one unit per semester, and it was found that several science teachers are in charge of Science Laboratory Experiments to fill the insufficient number of hours regardless of major. In the in-depth interview, science teachers argued that Integrated Science should be reduced and restructured by strengthening key competencies in preparation for the high school credit system. Based on the research results, ways to reorganize Integrated Science focused on big ideas, ways to construct common science courses based on fundamental science concepts that can guide elective courses, the necessity of career guidance through common science courses, and the necessity of strengthening teacher professionalism for teaching interdisciplinary and multidisciplinary subjects were suggested.
