The purpose of this study was to investigate the awareness of elementary school teachers on the socio-scientific issues. Fukushima Nuclear Power Plant Accident was used by concrete issue connected with SSI for this study. Participants in this study were twelve elementary school teachers studying at K University Graduate School of Education, located in the central region, who underwent a semi-structured interview. The study method was the phenomenological research method which is one of the qualitative research methods, and the interview papers had been examined by three scientific experts. As a result of the study, it was divided into twenty six themes, eight theme clusters, and two categories, and considered the thoughts on the Fukushima nuclear power plant accident, its influence on Korea, the relationship between science and society as a result of the Fukushima nuclear power plant accident, interested in social issues related to science, application in class, response from students and the influence on students. Teachers had a general understanding of science-related social issues, but did not have much interest in the subject. However, they mentioned that to apply the issues in the curriculum would have a positive influence and encourage scientific motivation in students and, furthermore, helped them to develop the awareness of science in their surroundings. A greater interest in socio-scientific issues need to require from teachers and, through including these issues in the curriculum, we should have positive influence in developing science education.

This study aims to introduce the ENACT model, which is a systematic teaching-learning model for cultivating social responsibility of science and engineering college students, and to discuss its educational implications. For the development of the ENACT model, we conducted extensive literature reviews on RRI, STEM education, and science and technology studies (STS). In addition, we examined exemplary overseas education programs emphasizing social responsibility of scientists/engineers and citizens. The ENACT model consists of five steps; 1) Engage in SSIs, 2) Navigate SSIs, 3) Anticipate consequences, 4) Conduct scientific and engineering practice, and 5) Take action. This model links Socioscientific Issues (SSI) education with engineering education, dividing the major elements of social responsibility education for scientists and engineers into the dimensions of epistemology and praxis, and reflected them in the model. This effort enables science and engineering college students to pursue more responsible and sustainable development by carrying out the responsible problem-solving process based on an understanding of the nature of science and technology. We plan to implement ENACT model based programs for science and engineering college students and to examine the effects.

본 연구의 목적은 기후변화 관련 사회적 논쟁 활동에서 신문기사 읽기에 따른 고등학생들의 소집단 의사결정 과정의 양상을 분석하는 것이다. 과학과 관련된 사회적 논쟁(SSI) 관련 수업 맥락에서 학생들이 접하는 정보는 절대적으로 신문이나 TV 등의 미디어 텍스트라는 점에서 텍스트와 의사결정 과정간의 관계를 밝히는 것은 중요한 문제라 할 수 있다. 연구에는 경기도 소재 고등학교에 재학 중인 1, 2학년 학생 22명이 참여하였다. 학생들에게는 유엔 기후변화협약 당사국 총회에 대해 보도한 두 편의 신문기사가 제공되었으며, 파리기후변화 협정에 우리나라가 가입하는 것에 동의하는지에 대한 개인 및 소집단 의사결정을 요구하였다. 신문기사는 비판적 담화분석에 근거해 분석하였으며, 소집단 의사결정 과정은 문제인식과 대안 평가 및 선택에서 드러나는 특징에 주목했다. 신문기사 분석을 통해 기후변화협정은 각국의 경제적 이권과 패권의 추구라는 복잡한 이데올로기가 자리잡고 있음을 확인할 수 있었다. 한편 소집단의 문제인식 단계에서 기후변화협정에 대해 학생들이 지니는 상이한 프레임과 신문기사가 전경화한 주요 담론은 소집단이 논쟁점을 인식하는 데 주요한 변인이 됨을 알 수 있었다. 대안평가 및 선택 단계에서는 공정성과 공평성이 소집단 토의의 주요한 준거로 작용했는데, 이 역시 신문기사에서 강조된 담론과 일치하는 것이었다. 본 연구는 SSI 맥락에서 타당하고 합리적인 판단을 위해 텍스트를 비판적으로 읽을 수 있는 능력을 길러 줄 과학적 소양 교육의 필요성을 함의한다.

3D two adjacent buildings with different heights founded in different kinds of soil connected with viscous dampers groups, with especial arrangement in plane, were investigated. Soil structure interaction for three different kinds of soil (stiff, medium and soft) were modeled as 3D Winkler model to give the realistic behavior of adjacent buildings connected with viscous dampers under various earthquake excitations taking in the account the effect of different kinds of soil beneath the buildings, using SAP2000n to model the whole system. A range of soil properties and soil damping characteristics are chosen which gives broad picture of connected structures system behavior resulted from the influence soil-structure interaction. Its conclusion that the response of connected structures system founded on soft soil are more critical than those founded on stiff soil. The behavior of connected structures is different from those with fixed base bigger by nearly 20%, and the efficiency of viscous dampers connecting the two adjacent buildings is reduced by nearly 25% less than those founded on stiff soil.

This study aimed to introduce a case study of a basic engineering design course using the ENACT model for fostering social responsibility of engineers, and to investigate the educational effects of the course. Since the ENACT model was designed to encourage STEM college students to pursue responsible problem solving based on their understanding of socioscientific issues, we assumed that it would be beneficial for engineering students to foster their social responsibility as well as their understanding of science/engineering-related issues. A total of 49 engineering students who enrolled in the course participated in the study. Data included students' course artifacts, reflection papers, and responses to survey questionnaires. Results indicated that the students became more aware of nature of science and technology after the program, and began to solve the problems while considering the views of multiple stakeholders. They highly valued the experience of communicating with others as engaging in the civic activities. They also expressed high satisfaction and feeling of achievement on the course learning. We expect the ENACT model to be an effective teaching guideline that fosters the social responsibility of engineering students and furthermore, engineering ethics.

Purpose: This study compares differences in stress, depression and suicidal ideation between nursing and students of other academic disciplines. Method: Nursing students (n=105) and students of other majors (n=148) were surveyed on the degree of personal stress, depression and suicidal ideation. Participants were recruited from three universities in cities S and C in Korea. Data were collected from May 1 to 20, 2013. Measurement tools were the Revised Life Stress Scale for College Students, Center for Epidemiological Studies-Depression Scale(CES-D), and Scale for Suicide Ideation(SSI). PASW Statistics 18 was used for descriptive analysis, homogeneity test(chi-square distribution) and ANCOVA. Results: The level of stress among nursing students was lower than that of students in other majors. Among the subcategories of stress, however, stress among nursing students arising from the student-faculty relationship was higher than that of their non-nursing counterparts. Conversely, differences in the prevalence of depression were notsignificant between nursing students and non-nursing students. Ultimately, it was revealed that there exists a strong correlation among stress, depression and suicidal idea for nursing students. Conclusion: Developing stress and depression management programs for nursing students is highly recommended.

Real-time substructuring techniques are currently an advanced experimental method for testing large size specimens in the laboratory. In dynamic substructuring, the whole tested system is split into two linked parts, the part of particular interest or nonlinearity, which is tested physically, and the remanding part which is tested numerically. To achieve near-perfect synchronization of the interface response between the physical specimen and the numerical model, a good controller is needed to compensate for transfer system dynamics, nonlinearities, uncertainties and time-varying parameters within the physical substructures. This paper presents the substructuring approach and control performance of the linear and the adaptive controllers for testing the dynamic characteristics of soil-structure-interaction system (SSI). This is difficult to emulate as an entire system in the laboratory because of the size and power supply limitations of the experimental facilities. A modified linear substructuring controller (MLSC) is proposed to replace the linear substructuring controller (LSC).The MLSC doesn't require the accurate mathematical model of the physical structure that is required by the LSC. The effects of parameter identification errors of physical structure and the shaking table on the control performance of the MLSC are analysed. An adaptive controller was designed to compensate for the errors from the simplification of the physical model in the MLSC, and from parameter identification errors. Comparative simulation and experimental tests were then performed to evaluate the performance of the MLSC and the adaptive controller.

The aim of this study was to identify students' views on the orientation of science and to investigate the relationship between their views and decision-making on socio-scientific issues (SSI). In this study, 27 university students attending a science course were asked to discuss four controversial issues: the Toyota recall, the green car, the global warming and swine influenza (influenza A (H1N1)). The study was comprised of two stages. At the first stage, we examined students' views on the nature of science and on the orientation of science with the open-ended questionnaire based on VNOS and VOSTS. While they held relatively similar views on the nature of science, their views on the orientation of science were distinct as pragmatic, intrinsic, communal and ethical views. At the second stage, to examine the role of their views on the orientation of science in decision-making, we selected four students who had similar views on NOS but different views on the orientation of science. The four students were selected from each group of views on the orientation of science and their decision-making processes were analyzed following grounded theory. Across SSIs, they relied upon their views on the orientation of science as the strategies for decision, though considered different perception, and causal and contextual conditions. This study indicates that understanding students' views on the orientation of science would be helpful for achieving scientific literacy for informed decision.
