  • This article arose from the previous studies, which suggested a synthetic list for the nature of science (NOS), discussed the relationship between the NOS and scientific inquiry and the development of the NOS in the context of scientific inquiry. In this article, for teaching scientific inquiry through the NOS, I proposed three teaching models - reflection, interaction, and the direct model -. Within these teaching models, understanding the NOS is viewed as a prerequisite condition for the improved performance of scientific inquiry. In the reflection model, the NOS is embedded and reflected in scientific inquiry without explicit introduction or direct explanation of the NOS. In the interaction model, concrete interaction between scientific inquiry and the NOS is encouraged during the process of scientific inquiry. In the direct model, subsequent to directly comprehending the NOS at the first stage of activity, students conduct scientific inquiry based on their understanding of the NOS. The intention of this present article is to facilitate the use of these models to develop teaching materials for more authentic scientific inquiry.

  • The purpose of this study was to investigate inservice elementary teachers' view and the change of preservice elementary teachers' view on the nature of science by the science education course. The subjects were 386 junior preservice teachers in a National University of Education and 257 inservice teachers working in a metropolitan city. An instrument consisting of fifty eight items were developed on the bases of previous studies. Before entering the course, preservice teachers view was compared by gender with T-test and no significant differences were found except the category 'role of a scientist'. Preservice teachers view was also compared by major with ANOVA and significant differences were found on the categories 'scientific method' and 'scientific law'. After the course, on comparing their view by gender, significant differences were found on the categories 'scientific theory', 'scientific knowledge', and 'scientific law'. The result of ANOVA by major, significant differences were found except the category 'role of a scientist'. Inservice teachers view was compared by gender and major and the differences were no significant, the significant differences, however, were founded in comparing by career and ability.

  • In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

  • 과학의 본성이 과학 교육에서 차지하는 의미에 비하여 실제 과학 영재교육에서는 과학 영재들의 과학의 본성에 대한 인식을 향상시키기 위한 획기적인 수업이 제공되고 있지 않다. 과학영재 담당 교사들에게 과학의 본성에 대한 효율적 수업 구성을 위한 기초 자료를 제공하고자, 본 연구의 과학 영재들의 과학의 본성에 대한 인식을 알아보고 인식 간에 존재하는 상충된 관점을 파악하였다. 연구는 서울의 한 대학부설 영재센터에 재학 중인 중학생 과학영재 73명을 대상으로 VNOS를 활용하였다. 인식조사 결과, 과학영재 학생들은 '과학지식의 잠정성' 영역을 제외한 다섯 개 영역에서 인식의 개선이 요구되었고 과학의 본성영역 간에도 서로 일치하지 않는 관점을 보였다. 과학 영재학생들의 과학의 본성에 대한 인식을 전문가적 관점으로 향상시키고 각 요소 간에 일관적인 관점을 갖도록 이끌기 위하여 두 가지를 제안한다. 첫째는, 실험 자료와 과학적 지식에 대한 인식을 변화시키기 위해 지식을 확인하기 위한 실험에서 지식을 구성해가는 과정을 강조하는 실험으로 바뀔 필요가 있다는 것이다. 둘째는 과학에 대한 안목을 넓히기 위해 과학자 문화와 과학자 공동체에 다양한 방법으로 경험할 기회가 제공되어야 할 것이다.

  • An alternative vision for science inquiry that appears to be important and challenging is model-based inquiry in which students generate, evaluate and revise their explanatory model. Pre-service teachers should be given opportunities to develop and use their mechanistic explanatory models in order to participate in the practice of science and to have a sound understanding of science. With this view, this study described a case of pre-service elementary teachers' scientific modeling in magnetism. The aims of this study were to explore difficulties preservice elementary teachers encountered while they engaged in a model-based inquiry, and to examine how their understandings of the nature of scientific models changed after the model-based inquiry. The data analysis revealed that the pre-service teachers had difficulties in drawing and writing their own thinking because they had little experience of expressing their own science ideas. When asked to predict what would happen, they could not understand what it meant to make a prediction "based on their model". They did not know how to use or consider their model in making a prediction. At the end of the model-based inquiry they reached a final consensus of a best model. However, they were very anxious about whether the model was the "correct" answer. With respect to the nature of scientific models, almost all of the pre-service teachers initially viewed models only as a communication tool among scientists or students and teachers to help understand others' ideas. After the model-based inquiry, however, many of them understood that they could create, test, and revise their "own" models "by themselves". They also realized the key aspects of scientific models that a model can be changed as evidence is accumulated and a model is a knowledge production tool as well as a communication tool. The results indicated that pre-service elementary teachers' understandings of the nature of scientific models and their previous school science experiences could affect their performance on a model-based inquiry, and their experience of scientific modeling could help them enhance their understandings of the nature of scientific models.

  • This article reviews the multiscale nature of stress corrosion cracking (SCC) observed by high-resolution characterizations in austenite stainless steels and Ni-base superalloys in light water reactors (including boiling water reactors, pressurized water reactors, and supercritical water reactors) with related opinions. A new statistical summary and comparison of observed degradation phenomena at different length scales is included. The intrinsic causes of this multiscale nature of SCC are discussed based on existing evidence and related opinions, ranging from materials theory to practical processing technologies. Questions of interest are then discussed to improve bottom-up understanding of the intrinsic causes. Last, a multiscale modeling and simulation methodology is proposed as a promising interdisciplinary solution to understand the intrinsic causes of the multiscale nature of SCC in light water reactors, based on a review of related supporting application evidence.

  • Human behaviour normally depends on the environment of the incident and the time of its occurrence. The behaviour of people depends on many factors and these behaviour traits are an important aspect in the Library and Information Science (LIS) field. Hence in this paper an attempt has been made to examine the behaviour traits of LIS students in South India. Out of 400 questionnaires distributed 367 have responded and the response rate is 91.75%. In this survey three aspects comprising student behaviour have been analysed such as Work Environment, Natural Environment, and Social Environment. In the case of Work Environment the respondents were grouped as Workaholic, Impatience, Achievement oriented, Rash nature, and Punctuality. Further, in respect to Natural environment, the respondents are grouped as Complacent, Patience, Easygoing, and Relaxed. Last, the respondents were grouped in the Social Environment as Balancing nature, Magnanimity, Naturalistic, Assertive nature, Dependency, Lucrative, Lonely nature, and Time Based personality. Finally the authors conclude that LIS students need to possess these qualities and behaviours to work in different environments.

  • This essay examines Jacques Callot's Les Grandes Mis$\grave{e}$res et Malheurs de la Guerre (1633) as a moral meditation on war as catastrophe. It also uses Callot's Miseries to reflect on the nature of catastrophe as such, particularly as "An event producing a subversion of the order or system of things." As such, catastrophe refers less to nature or the natural gone awry, than it does to the abnegation or suspension of moral aspects of human nature. More than a reflection on war as catastrophe, and catastrophe as fundamentally moral, Callot's Miseries are a timeless meditation on aspects of the human condition; or on human beings in what amounts to state of nature-as evidenced in times of disaster. Such reflection, again, does not by itself imply that all war-even when catastrophic-is unnecessary, let alone necessarily unjust. But it does suggest that artistic engagement with war understood as catastrophic, may yield insights into human nature that are as important to human self-understanding as those represented in artistic subject matter that is more quotidian.

  • A human being has been using more and more materials for promotion of its life level year by year. The materials are originated from the Nature. We must think that a human being temporarily borrows them from the Nature. So we should return them in the same form as the origin into the Nature. However, it is impossible because it has been irreversibly changed into different phase. This attributes destruction of the Nature, i.e., pollution of the Nature. For environmental prevention of the Nature from pollution, we should try the entire recycling of materials by returning the used materials in the safe from even if it has a different phase in comparison with the original state. This article proposes the entire recycling of materials lot keeping the EARTH.
