The purpose of this research was examining the effects of problem-based learning strategies(PBL) on problem solving skill conducted in Korea, using meta-analysis technique. This meta-analysis reviewed the results of 41 studies published between 1998 and 2017 in Korea. The overall weighted mean effect size value was .753 with .064 standard error which was calculated by random effects model. PBL strategies have been found to be more effective in mathematics course (d=.922), art course (d=.916), practical art course (d=.827), E-PBL (d=.791) and middle school level (d=.972). As PBL exhibit a substantial effect on students' problem solving skill, it is recommended that teachers should learn how to implement these strategies in their lesson. PBL is expected to contribute to the improvement of teaching methods as the learning environment changes during the 4th Industrial Revolution.

Outer Space is existing as the opening-up frontier. The space activities included benefit-and-risk are now confronted with the challenge of arriving at just and effective rules for the use of space serving many technical, practical and conflicting legal, economic, political and military interests. Therefore many governments have developed domestic and international policies to respond to the opportunities and constraints engendered by space exploration and exploitation. the challenges of outer space toward the 21st century are being internationalized, commercialized, and privatized, militarized through the international cooperation and competition in space activities. For the future of mankind, futhermore the right to live of humankind, we must be positively interested in international space law which may give rise to international repercussions. I suggeste that many issues be resolved by international coordinating organization.

This study was undertaken to analyze the intervening effect of nursing simulation among nursing students. This was a critical review study, and data obtained were reviewed using various data bases, including RISS, KISS, NDSL, DBpia, and KRI. The terminologies entered in the data base were nursing and simulation. Selected studies were assessed for methodological quality; and narrative, descriptive or one group post-test studies were excluded from the analysis. Ed. Notes: Please review for accuracy. I have suggested the edit to the best of my understanding. Finally, 234 studies were included for investigation. Results included studies of nursing simulation intervention in Korea, commencing from 2008. One group pre-post test and two group post test were more designed in journals comparing to master thesis or doctoral dissertation. Clinical practice was the most frequently studied aspect by both the assessor and student in the two groups' pre-post test design. Nursing competences associated with dependent variables during simulation were integrated skills, critical thinking, communication, cooperation, professional recognition and leadership. The two groups pre-post design explored more varied competences as compared to other designs. Considering the results obtained, we conclude that simulation intervention is an effective teaching method for nursing students to help improve their clinical practice. However, further studies are required to assess the impact of critical thinking and problem solving.

습지 분류의 목표는 '목록작성(inventory)과 평가와 관리를 위해 자연적인 생태계에 범위를 설정하는 것'이다. 또한 등질적인 속성을 갖는 생태단위를 기술하고, 자원관리 의사결정에 도움을 줄 수 있는 체계로 단위를 만들어내고, 목록작성과 지도화에 필요한 단위를 제공하면, 습지에 관한 개념과 용어의 통일성을 제공하는 것 등이다. 해안지형 가운데 해안 습지의 분류에는 우선, 1) 형태, 2) 생성요인, 3) 자갈, 모래, 펄 같은 기질 물질과 4)현재의 환경이라는 요소가 모두 고려되어야만 하는데 아직 국내에는 이에 대한 연구가 절대적으로 부족하여 이에 대한 규정이 부족한 현실이다. 따라서 현 단계에서 ISO/IEC 규정대로 각 코드는 엄밀히 상호배타적인 개념일 것, 정수로 표시할 것과 순차적으로 증가하는 숫자로 표시할 것 등의 전제조건을 만족시키는 전제 하에서 해안습지를 분류하는 것은 매우 힘든 작업이라 생각한다. 하지만 국토공간의 효율적 관리와 보존을 위해서는 위치와 장소에 따라 차이를 보이는 지질, 지형, 토양, 식생, 수리 현상 등 제반 지표 환경요소에 대한 체계화된 정보의 축척이 있어야 가능하다. 우리나라의 경우 지질 정보는 지질자원연구원에서 발행하는 지질도와, 농촌진흥청에서 발행하는 토양도, 임업연구원에서 발행하는 임상도 등의 주제도가 있으나, 지표환경을 나타내주는 지형에 대한 정보체계는 아직 이루러진 바가 없고, 대학의 석사학위논문이나, 실험적인 수준의 연구에 머물고 있는 실정이다. 이번 연구에서는 지형분류도 작성과 관련한 외국의 사례를 집중적으로 분석하고, 지형정보의 체계적 관리를 위해 가장 필요한 해안습지 지형분류도를 작성하기 위해 가장 기초적인 단계인 해안습지 지형분류체계에 대한 국내외의 연구성과를 비교하여 시안을 작성 표준화를 위한 첫 단계 시도를 소개하였다.분석 결과는 문장, 그림 및 도표, 장 끝의 질문, 학생의 학습 활동 수 등이 $0.4{\sim}1.5$ 사이의 값으로 학생 참여를 적절히 유도하는 발견 지향적 인 것으로 조사되었다. 그러나 장의 요약은 본문 내용을 반복하는 내용으로 구성되었다. 이와 같이 공통과학 과목은 새로운 현대 사회에 부응하는 교과 목표와 체계를 지향하고 있지만 아직도 통합과학으로서의 내용과 체계를 완전히 갖추고 있지 못할 뿐만 아니라 현재 사용되고 있는 7종의 교과서가 교육 목표를 충분히 반영하지 못하고 있다. 따라서 교사의 역할이 더욱더 중요하게 되었다.괴리가 작아진다. 이 결과에 따르면 위탁증거금의 징수는 그 제도의 취지에 부합되고 있다. 다만 제도운용상의 이유이거나 혹은 우리나라 주식시장의 투자자들이 비합리적인 투자형태를 보임에 따라 그 정책적 효과는 때로 역기능적인 결과로 초래하였다. 그럼에도 불구하고 이 연구결과를 통하여 최소한 주식시장(株式市場)에서 위탁증거금제도는 그 제도적 의의가 여전히 있다는 사실이 확인되었다. 또한 우리나라 주식시장에서 통상 과열투기 행위가 빈번히 일어나 주식시장을 교란시킴으로써 건전한 투자풍토조성에 저해된다는 저간의 우려가 매우 커왔으나 표본 기간동안에 대하여 실증분석을 한 결과 주식시장 전체적으로 볼 때 주가변동율(株價變動率), 특히 초과주가변동율(超過株價變動率)에 미치는 영향이 그다지 심각한 정도는 아니었으며 오히려 우리나라의 주식시장은 미국시장에 비해 주가가 비교적 안정적인 수준을 유지해 왔다고 볼 수 있다.36.4%)와 외식을 선호(29.1%)${\lrcorner}$ 하기 때문에 패스트푸드를 이용하게 된 것으로 응답 하였으며, 남 여 대학생간에는 유의한 차이(p<0.05)가 인정되었다. 응답자의 체형은 ${\ulcorner}$

The purpose of this research is to analyze the mathematical tasks of length measurement in two different perspectives, the level of cognitive demands and learning trajectories, and restructure the mathematical tasks so that the students' conceptual learning is promoted and students are able to have opportunities to think more broadly. Ten lessons with the restructured mathematical tasks were implemented for a class of 2nd grade elementary students. Also a qualitative and in-depth study was conducted with 4 students of the target group. The study shows that firstly, the restructured tasks requiring high level of cognitive skills, had positive effects in increasing the students' level of thinking and reasoning. Secondly, the tasks modified according to the learning trajectories of Szilag, Clements & Sarama(2013) in length measurement, have proven to promote students' concept learning and elaborate the students' level of thinking.

This study analyzes diverse research studies on psychomotricity as convergence of psychological and physical exercises and aims to identify challenges and provide solutions for more extensive future research. The study collected 50 papers published in Korea from 2013 to March 2017 through paper search systems and analyzed the distribution of the works by types and research subjects, and types of research design, types of dependent variables and the number of interventions involved. By research design, it was found that most number of papers were based on single-subject research, followed by quantitative research. Motor development appeared the most as a dependent variable, followed by sociality and emotional behavior. Most number of studies involved 21-30 times of interventions. The changes in the research results were analyzed in the order of sociality, motor development, and behavior change. Future psychomotricity studies need to expand study subjects and diversify research methods and variables, with active follow-up studies contributing to social service by providing comprehensive solutions.

The purpose of this study was to analyze trends in conceptual change research in the field of Earth Science education conducted in Korea and to provide them as basic data of future concept change research. The trends of conceptual change research were analyzed in terms of keywords, year of publication, source of research, purpose of research, subject, area of research, and research method. This study was carried out on a total of 126 conceptual change papers of Earth Science education published from 1989 to July 2017. This study showed the following conclusions: First, the conceptual change research papers used more the term 'conceptual change' than 'misconceptions' and 'preconceptions'. Second, the conceptual change paper has achieved a large amount of growth in the 2000s. Third, conceptual change research tended to proceed to the subject of master's dissertation. Fourth, there were a lot of researches to find out the misconceptions and change them into the right concept, the conceptual change paper used free response test for misconceptions, and cognitive conflict instruction model and CAI (Computer Assisted Instruction) teaching strategy for misconceptions. Fifth, elementary school students were studied the most. Sixth, the study of conceptual changes in the field of Earth Science was high in the astronomical and atmospheric areas. Finally, although quantitative analysis methods were used in the early days of research, in the 2010s, qualitative analysis methods were widely used. In this paper, we proposed research on conceptual change for pre- and in-service teachers, expansion of research on conceptual changes in various fields such as geology, oceanography, atmosphere in Earth Science, investigation of causes of misconception in Earth Science and research on individual's affective factors, and so on.

This study will show the determinants of research productivity by fields in science and engineering. However, we present the differences between fields by personal attributes, research resources, and research productivities. The data includes 1,383 researchers who participated in the BK21 PLUS program during 2010-2012. The fields are physics, chemistry, biology, mechanics, electricity and electronics and chemical engineering. As for research productivity, 3 indices are used such as the number of papers publicized, patents and combination of papers and patents. As for explanation factors, two kinds of variables are used. The personal factors include sex, age, academic rank, location of affiliation, and country of PhD acquisition, and the resource factors are the number of graduate students, 3 types of research funds such as government fund, industrial fund and overseas fund. This study is unique in several aspects; Dealing with 3 productivity indices, and using massive official data, 6 different fields, and determinants of research productivity. The results are as follows; 1) there is a big difference in determinants by fields. 2) No variables affect the research productivity of all the fields at the same time. 3) In science, the number of determinants are quite low than engineering. 4) The ratio between papers and patents are different by fields. 5) The correlations between paper and patent by fields are different; no relationship in the field of physics and chemistry and positive relationship in the other 4 fields.
