The purpose of this study was to investigate the association between subject matter knowledge (SMK) and pedagogical content knowledge (PCK) for science teachers. To this end, a total of 26 secondary Earth science teachers participated in this study and a concept diagnostic questionnaire and a lesson planning task of atmospheric pressure were devised to give an indication of participating teachers' SMK and PCK, respectively. The results of this study are summarized as follows: First, participating teachers showed a variety of SMK levels about atmospheric pressure. Second, teachers at high level of SMK focused on 'supplementary' and 'fundamental' curriculum contents for in-depth conceptual understanding, but teachers at low level of SMK, on the contrary, stressed 'applicative' curriculum contents. Third, teachers at high level of SMK grasped students' misconceptions and difficulties in learning atmospheric pressure far more concretely than teachers at low level of SMK. Lastly, teachers at high level of SMK showed a tendency to use learner-centered instructional strategy by utilizing students' prior knowledge, but teachers at low level of SMK were inclined toward teacher-directed concept explanation. Based on this study, some implications for effective science teacher preparation programs were also discussed.

Creative thinking alone can not lead to scientific creativity. Scientific knowledge and scientific inquiry skills are needed for scientific creativity. Focused only on cognitive aspect, I suggested a cognitive model of scientific creativity (CMSC) consisting of 3 components: thinking for scientific creativity, scientific knowledge contents, and scientific inquiry skills. Recently, many researchers have emphasized the various thinking for creativity as well as divergent thinking. Therefore, I suggested three types of creative thinking - divergent thinking, convergent thinking, and associational thinking - and discussed its rationale. Based on this model, an example of activity material for the scientific creativity was suggested. In the further research, based on CMSC, various activity types related to scientific creativity and concrete learning materials for scientific creativity will be developed.

The present study was performed to analyze and review the physical and immune responses to overtraining syndrome in humans. Overreaching refers to the initial phage of overtraining syndrome and has been known as a physical fatigue which is mainly from metabolic imbalance. It has been known that overtraining also results in a loss of adaptability which may lead to an attenuation of exercise performance, sleeping disorder, central fatigue, neurohormonal changes, difficulty recovery to physical stress, and immunological changes. Additionally, overtraining syndrome is characterized by persistent fatigue, poor performance in sport due to the prolonged and strenuous physical training. Also, previous studies reported that endurance athletes experienced a high incidence of URTI during intense training and the post training. And also, high-performance athletes reported that suppression of cell mediated and anti-body mediated immune function. NK cell numbers were also reduced in the period of overtraining syndrome. Major components of prevention and treatment for the overtraining syndrome are screening, education, and detraining. Furthermore, the combination of these prevention and treatment strategies will be much helpful. Therefore, the current review will be helpful for athletes and individuals who are at the risk of overtraining syndrome.

The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

This paper aims from various angles to examine the context of the problem situations that Jang Woo-Jae describes from contemporary korean society, to examine which chance of thinking is in this case given to the audience, and to examine whether through the plays in the theater this chance of thinking can be referred to public opinion. This study considers not only the contribution of Jang's thought experiment that is connected to the dramaturgical function including the aspects of dramatic form and content to dramatic effects for the audience, but also the possibility of an arrangement for a new way of thinking by the audience. Thus, Jang's thought experiment should be understood in connection with the whole message of his plays. And this study researches, how an new attention to the public nature of common world, which should be demanded for the sake of a mature civil society comes into existence within the point of contention in every play based on Jang's thought experiment. Finally this paper inspects through Jang's plays the possibility of contribution of performing art to contemporary korean society, and takes account of self-examination in meta-dimension of the theater regarding the role and meaning for the sake of human being and gemeinschaft.

The Interdisciplinary-Multistrategic Science Education Program(IMSEP) is designed as an efficient program for the education of the gifted in science. An example of the contents is developed, which encompasses mathematics, physics, chemistry, astronomy, and biology. In the program, the complexity(interdisicplinarity) of scientific contents and instructional strategies used to deliver the scientific contents are designed to be correlated to each other in such a way that as the scientific contents gets more complex, the scientific skill to be taught by the instructional strategy becomes deeper. Through the careful balance between the scientific contents and the instructional strategies student's scientific knowledge and scientific skill will develop balanced and the effectiveness of science education will be maximized.

The purpose of this study is to analyze the contents of 'housing' unit in middle school Technology-Home Economics textbooks according to the 2015 revision curriculum based on the targets of SDGs. All contents of the ten textbooks of five publishers, such as texts, photographs/figures/tables, activity tasks, and supplementary materials were analyzed in terms of SDGs targets. The number of 'housing' contents among 4 small housing units of Technology-Home Economics book 1 & 2 varied from 64 to 97 by publishers. Beside SDGs4.7, which contains inclusive and general ESDGs, 24 targets of 10 SDGs were found to be related to the contents of 'housing' and were grouped into 15 target categories. The number of SDGs target categories related to housing contents of each small unit and total of all units differed by publishers. Each of 4 small 'housing' units from all the five publishers was related to 6~10 target categories. The contents of five book 1's were related to smaller number of target categories than those of five book 2's. They corresponded to 9 and 12 target categories, consecutively. Only SDGs' target11.1 (appropriate and safe housing and basic services) was related to all the four small units of 'housing' contents among all the five publishers. covering 43.8% of the housing contents. In conclusion, the contents of the 'housing' unit were related to broad range of SDGs targets. Further study could relate goals of teaching-learning plan to various global targets of SDGs according to the contents of 'housing' in order to accomplish ESDGs.

담수 저서 생물군 중의 하나인 연체동물은 인간 생활에 있어 매우 중요하다. 이들은 먹이사슬(food chain)과 깊이 연관되어 있고 하상 퇴적물의 찌꺼기를 섭취하는 청소자로서의 역할 뿐 아니라 안간의 식용으로 이용되기도 한다. 어떤 종은 생태학적 지표종으로서의 역할을 하며, 어떤 종들은 지리적 특성과 연관성을 연구하는데 대상이 될 뿐 아니라 과거의 수계 형성과정을 추정하는데 중요한 역할을 한다. 부정적 측면으로는 한국 담수산 권패류의 몇몇 종류는 인체의 흡충류 기생충을 전달하는 그들의 역할 때문에 실제 문제시 되고 있다. 그들의 이 같은 중요성에도 불구하고, 한국산 담수 연체동물에 대한 깊은 연구가 이루어지지 않고 있는바, 이는 부분적으로 한국에 서식하는 연체동물상을 동정함에 있어 쉽게 이용될 수 있는 적당한 분류체계가 부족하였기 때문이다. 본 논문의 첫째 목적은 한국산 담수 권패류를 속(genus)수준까지 동정할 수 있는 색인을 마련하고 그 분류기준을 세우는데 있으며, 둘째로는 한국산 담수 권패류에 대한 광범한 문헌을 수집하고 중요한 문헌의 순서에 따라 그 내용을 간략히 요약하여 앞으로의 연구자득에게 도움을 주고자 한 것이다.
