  • In an era of global competition, international cooperation in science and technology plays a key role in determining a nation's competitiveness. In fact, without international cooperation, it is almost impossible to keep in touch with the fast-changing technology. In regard to this, the Korean government put much efforts into building a strong base for global R&D networking. As a result, the environment for international cooperation has improved a lot. However, the outputs of international cooperation are still poor and fall short of expectations. With the importance of international cooperation in science and technology rising more and more, it is meaningful to examine the current situation of international cooperation in S&T and analyse the outputs of the cooperation activities to review our past and present international cooperation activities. Therefore, this paper focuses on analyzing the outputs of the MEST's international S&T cooperation programs in various ways and recommends ways to improve the outputs of the international cooperation in science and technology.

  • The extended science investigations, comprehensive investigations contrasted with exercises of process skill components and cookbook style experiments, should be pursued for giving opportunity of more authentic science activity. The characteristics of the extended investigation tasks were emerged from critical argument on school practical work. And one of important educational objectives in students' investigations is to achieve motivation for investigation. The purpose of this study is to explore how the characteristics of the extended investigation tasks, that is practical context, openness and continuity, affect middle school students' motivation for investigation. On the basis of questionnaire results and students' school science achievement, ten students were interviewed to see the change of motivation for investigation and its causes while they perform two textbook investigations and four extended investigation tasks. Among the interviewees, the students who showed positive motivation for the extended investigations were critical about textbook experiments as they are just confirmations of theories and perceived practical context and openness as the main causes of their positive motivation. The students who showed negative motivation for extended investigations preferred textbook experiments as there was enough guidance from teacher and textbook-centered learning. They recognized the openness of the tasks as a main reason of their negative motivation for investigation. Some students showed negative responses about continuity of the extended investigation tasks but continuity was not recognized as a main cause for their motivation for investigation.

  • This study is a study of factors affecting pre-service teachers' learning immersion in online science classes. The results of a survey on the responses of 88 pre-primary teachers to online science classes were interpreted. In online science class, independent variables were set as ease, usefulness, and social presence, and dependent variables were set as learning immersion. Online science classes were conducted based on the university's LMS system. The results of the study were interpreted by regression analysis for t-test, correlation between factors, and multicollinearity test in pre-post-responses of pre-service teachers for ease, usefulness, and social presence. The results of this study are as follows. First, there was a significant effect in the before-and-after tests of factors in the online science class. Second, the correlation coefficient between factors in online science class is .306 for sense of community and mutual support and concentration at the significance level of .01, and .354 for learning immersion and open communication, indicating that there is a correlation. Third, considering the effective results of the pre-post test of each factor in the online science class, it cannot be interpreted that a particular factor had an effect, but it is interpreted that learning was immersed in ease, usefulness, and a sense of social presence.

  • APEX(Agricultural Policy Enviromental eXtender) 모형은 일 단위로 구동되며 필지단위 및 소유역 단위에서의 흐름을 장기 모의를 할 수 있는 모형이다. APEX는 유출을 포함한 토양 침식, 탄소 이동 등 다양한 자연현상을 모의할 수 있는 모형이다. 강우에 의한 직접유출량을 APEX를 이용하여 산정할 수 있지만, 모델링 과정에서 발생하는 불확실성으로 인하여 부정적인 요인이 발생한다. 따라서 본 연구에서는 APEX 모형의 유출 매개변수를 이용한 불확실성을 평가하고자 한다. 이를 위해서 금강권역에서 표준유역으로 분류되어있는 한천 유역에 대해 2008~2019년도 유출량을 모의하였으며, 검증을 위해 동일기간에 대해 기저유출분리를 수행하였다. 불확실성 평가를 위해서 Python 기반으로 사전분포로부터 매개변수를 임의로 선택하도록 설정하여 총 10,000번의 구동을 수행하였다. 불확실성 평가지표로는 NSE, PBIAS, RSR을 이용하여 평가하여 평가지표별 불확실성 구간을 비교분석 하였다. 본 연구에서의 APEX 모형의 불확실성 평가를 통하여 APEX의 활용성을 더욱 확대하고 신뢰성을 높일 것으로 기대한다.

  • Scientific creativity is defined as the production of novel scientific facts, methods, theories, explanations, and instruments, as well as the entire process by which these novel facts, theories, explanations and instruments are generated. There have been many studies on scientific creativity, but there were few studies on the scientific creativity of a research team collaborating in laboratory settings. This paper aims to find the elements that constitute the creativity of a laboratory through empirical participant observation and theoretical analysis of RNA Biology Lab in Seoul National University - a lab which is considered to be the most creative laboratory in Korea. Creative accomplishments demand not just a sudden inspiration but also a complicated and continuous evolutionary process which requires a systematic division of labor and a corporation between researchers who have diverse knowledges and capabilities. Also, this paper shows that laboratory culture and leadership are an important factor for vitalizing the corporative structure of the laboratory.

  • Vitiligo is a commonly acquired cutaneous depigmentation disorder that affects 0.5~1% of the population worldwide. While phototherapy is the primary treatment for vitiligo, surgical methods can be used for treating patients who are refractory to conventional treatments. Herein, we present the case of a 14-year-old Korean girl who developed vitiligo after hematopoietic stem cell transplantation for the treatment of acute lymphoblastic leukemia. She had multiple depigmented patches on her lower legs that did not respond to narrow-band ultraviolet B phototherapy for 7 months. The depigmented patches were successfully treated by transplantation of non-cultured epidermal cell suspension from the epidermal roof of the suction blister in the right inner thigh. No adverse event, such as secondary infection or scarring in both the donor and recipient sites, was noted. We recommended that non-cultured epidermal cell suspension transplantation using the suction blister method would be a safe and effective option for the treatment of refractory vitiligo.

  • This study explored the educational effects of the digital citizenship teaching and learning model on middle school science classes. For this purpose, two classes of the third grade of middle school in Gyeonggi-do were selected, and the experimental group(28 students) was taught science classes using digital citizenship learning model, and the control group(28 students) was taught in regular lectures. The measurements used to verify the effects of science classes using the digital citizenship learning model were digital citizenship and empathy tools. The data collected for the effect verification were analyzed by independent sample t-test and ANCOVA. As a result, the experimental group applying the digital citizenship learning model showed higher scores of digital citizenship and empathy than the control group. Therefore, it can be seen that the middle school science class applying the digital citizenship learning model was effective in cultivating the digital citizenship and empathy of middle school students. In future studies, it is necessary to examine the effects of digital citizenship learning model at different school levels and other subjects.

  • This study has investigated the factors that make a science teacher effective by analyzing students' perception of teacher knowledge required in enhancing their science learning. The basic components of teacher knowledge identified by previous researchers have been confirmed through Exploratory Factor Analysis (EFA). Based on the findings of the EFA, the questionnaire has been further analyzed using Confirmatory Factor Analysis (CFA) by means of Structural Equation Modeling (SEM). In addition, the differences in students' perception on the identified factors of effectiveness have also been analyzed in terms of gender and achievement level. The findings of the EFA showed that five factors of science teacher effectiveness were identified; namely, substantive knowledge, syntactic knowledge, knowledge of students' understandings, knowledge of instructional strategies, and knowledge of assessment. These five components have been divided into two categories of teacher knowledge, SMK and PCK. What we found from the CFA was the respective high correlation between substantive and syntactic knowledge, knowledge of students' understanding and instructional strategies and the low correlation between substantive knowledge and knowledge of instructional strategies. Students perceived substantive knowledge as the most effective factor, knowledge of assessment as the least effective factor. Also, there have been considerable differences in students' perception by gender and achievement level. We proposed, based on the findings, that SMK and PCK need to be integrated into a coherent manner for the effective science teaching practice. This study provides some implications for science teacher professional development and the improvement of science teacher preparation program.
