This study aims to investigate the primary teachers' perception of social emotional learning (SEL) in Malawi. To achieve this purpose, total 78 questionnaires were gathered from 9 primary schools in rural area. The data was analyzed with independent-samples t-test, correlation analysis, and multiple regression analysis. The results of this study are follows. First, the sub-factors of the Malawian primary teachers' perception of SEL shows that Comfort is 4.10, Commitment is 4.59, and Culture is 3.78. Second, there was a significant difference in the Malawian primary teachers' perception by age, years of teaching, and participation to in-service training about SEL among the individual characteristics. Third, the Malawian primary teachers' degree of implementation of SEL in school was 4.01, and there was a significant difference by years of teaching. Forth, among the sub-factors of teachers' perception of SEL, Comfort had a positive effect on the degree of implementation of SEL. This result implied that the reason why Malawian primary teachers had difficulty in implementing SEL in the school might be not a lack of individual competence but feel uncomfortable with implementation. Therefore, in order to implement SEL in the Malawi school, it is necessary to support teachers so they have confidence and comfort psychologically.

This article deals with one of the pansori master's life and activities. Bak Songhui(1927~2017), who was the holder of National Intangible Cultural Asset No. 5 for pansori Heungboga. She had played a significant role through the modern history of pansori genre including Yeoseong Gukkeuk(Korean classical opera by women) and Changgeuk(Korean traditional opera in pansori style) as well as original pansori itself. In the article, the early stage of her learnings and the way she got involved to pansori from Gwonbeon period are offered, and the activities by group, solo recitals, and educational activity lists are also provided. Bak Songhui began to learn pansori, Geommu(dance), Seungmu(dance), Gayageum, Yanggeum, and Gagok genres at her age of 13 in Gwangju. She fulfilled 5 years of study in Gwangju Gwonbeon, and entered to a Hyeomnyulsa-travelling theater company, led by Gim Yeonsu at her age around 19. Later, Bak used to be an actress in Yeoseong Gugak Donghohoe(Female Korean music fans' club) led by Gim sohui as well as in Haennim Gukkeukdan, and Saehan Gukkeukdan at around her age of 30. She took the main actress' role in several performances. And thanks to her effort, the Yeoseong Gukkeuk can be one of the representative genre in history. As she entered to the National Changgeuk company, her brilliant talents worked well by leading the company's big hit with her talents of taking many different characters, devotions, and know-hows from her experience. After her 70s, she kept the pansori go on its right way to pass down. She unfolded pansori performances as well as her own students' public presentations, recordings, TV and radio broadcasting activities as the holder of National Intangible Cultural Asset. The activities that Bak Songhui showed us can become another chance to make her a great master of pansori, especially in Dongpyeonje style.

It is important to measure the Arctic surface air temperature because it plays a key-role in the exchange of energy between the ocean, sea ice, and the atmosphere. Although in-situ observations provide accurate measurements of air temperature, they are spatially limited to show the distribution of Arctic surface air temperature. In this study, we proposed machine learning-based models to estimate the Arctic surface air temperature in summer based on buoy data and Advanced Microwave Scanning Radiometer 2 (AMSR2)satellite data. Two machine learning approaches-random forest (RF) and support vector machine (SVM)-were used to estimate the air temperature twice a day according to AMSR2 observation time. Both RF and SVM showed $R^2$ of 0.84-0.88 and RMSE of $1.31-1.53^{\circ}C$. The results were compared to the surface air temperature and spatial distribution of the ERA-Interim reanalysis data from the European Center for Medium-Range Weather Forecasts (ECMWF). They tended to underestimate the Barents Sea, the Kara Sea, and the Baffin Bay region where no IABP buoy observations exist. This study showed both possibility and limitations of the empirical estimation of Arctic surface temperature using AMSR2 data.

The purpose of this study was to analyze the problem solving strategies of ordinary students, gifted students, pre-service teachers, and in-service teachers with the 'chicken and pig problem,' which has multiple strategies to obtain the solution. For this study, 98 students in the 6th grade elementary schools, 96 gifted students in a gifted institution, 72 pre-service teachers, and 60 in-service teachers were selected. The researcher presented the "chicken and pig" problem and requested them the solution strategies as many as possible for 30 minutes in a free atmosphere. As a result of the study, the gifted students used relatively various and efficient strategies compared to the ordinary students, and there was a difference in the most used strategies among the groups. In addition, the percentage of respondents who suggested four or more strategies was 1% for the ordinary students, 54% for the gifted students, 42% for the pre-service teachers, and 43% for the in-service teachers. As suggestions, the researcher asserted that various kinds of high-quality mathematical problems and solving experiences should be provided to students and teachers and have students develop multi-strategy problems. As a follow-up study, the researcher suggested that multi-strategy mathematical problems should be applied to classroom teaching in a collaborative learning environment and reflected them in teacher training program.

The purpose of this study is to compare and analyze the perceptions of TPACK for mathematics teachers who practice the technology-using lessons. In addition, by looking at the part where the perception is expressed in the actual class and the part where the difference of recognition can be revealed, it is possible to provide the direction to teachers who want to practice the technology-using lessons in the future. To do this, two mathematics teachers were selected using purposeful sampling. And we conducted research study and interview in order to analyze the characteristics of the teacher's general background and TPACK recognition, and we analyzed the video, the class materials, and the interview contents for teaching practices from the perspective of TPACK. As a result, the two mathematics teachers practicing the technology-using lessons were connected with the actual class situation focusing on the sub-knowledges of TPACK recognizes as having a lot of them. In addition, technology-based lessons were able to confirm that the functional capabilities of technology alone were not sufficient conditions to lead effective instruction. Finally, teaching method using technology has been confirmed that experience-based field practice can be more important than simply knowing mathematics content, technology, teaching method. Based on the results of this study, it is possible not only to provide methodological guidance to teachers who practice the technology-based instruction, but also to suggest the direction of TPACK research or the development of teacher training program in the future.

Virtual Training is an educational exercise in which the environment or the situation is virtually implemented for specific training and proceed like a real situation. In recent years, the virtual reality technology has developed rapidly, and the demand for experiencing situation that are not directly experienced in the real world is increasing more and more in virtual reality. Particularly, there is an increasing demand of contents for hands-on training and virtual training for equipment training that replaces high-risk and high-cost industry training. The virtual training contents have been developed and utilized for the purpose of technical training. However, it is known that virtual training is more effective when it is used as a supplementary training material or combined with e-learning contents rather than replacing one training course with virtual training contents because purpose and effect are different from general technical training course. In this study, we explored the development method for effective utilization of electrohydraulic servo control process, which is the virtual reality contents developed in 2017 in combination with e-learning contents. In addition, in order to establish a teaching and learning strategy, we actually develop and operate a case studies using virtual training contents. Surveys and case studies are conducted to investigate the effects of teaching and learning strategies applied in the classroom on students and their educational usefulness.

Science museums are platforms of PUS (public understanding of science). The purpose of this study was to explore the science communicators' competencies critical in interacting with visitors from the comparison of their training and professional development programs nationally and internationally. The managers running science communicators' programs and communicators themselves from six different national science museums and those from five different international ones participated in the structured survey. The data from surveys were compared among respondents to draw common and specific descriptions for communicators' competencies. In addition, the experienced exemplary science communicator, Ms. Park, participated in this study and the data from her observation field notes, her own developed science communicators' manual, and interviews were used to support the result. The contextual model of learning in science museums (Falk, 2006) was used to illustrate science communicators' expertise. National managers and science communicators showed difference in their perception about science communicators' roles, difficulties, and improvement for their competencies. Internationally, the managers and science communicators showed similar perception about communicators' competencies in terms of the contextual model of learning. It is highly suggested that practice-based science communicators' training and professional development programs must be offered on the basis of interaction between experienced and novice communicators as mentors and mentees systems.

Riverine wetlands are an important element of the river ecosystem and account for approximately 38% of the inland wetlands surveyed so far. The Shincheon Wetland located in Mangyeong River is also a channel wetland as the flow rate is slowed by the constructed weirs, leading to sediment accumulation. To identify the conservation value and ecological characteristics of Shincheon Wetland, its vegetation and plant diversity were identified using a phytosociological method, and a total of 45 vegetation-related datasets were collected. Overall, 24 plant communities, comprising a total of 153 taxa (49 families, 117 genera, 146 species, 2 subspecies, 5 varieties) were identified. The plant with the highest appearance rate in the communities was Humulus japonicus Siebold & Zucc. In addition, annual herb species, including Rumex crispus L., Bromusjaponicus Thunb., Erigeron annuus (L.) Pers., and Artemisia indica Willd. were frequently observed to be growing in the secondary grassland. Naturalized plants were surveyed in the 38 taxa; the urbanization index was 10.3% and the naturalized index was 24.8%. Plant communities were largely classified into submerged vegetation, floating and floating-leaved vegetation, annual and biennial vegetation, perennial herb vegetation, and woody vegetation. The distribution of plant communities reflecting various habitats, including the lentic and lotic zone maintaining a constant water depth, littoral zone experiencing intermittent water level fluctuations, and dry floodplain environment was also confirmed. Overall, plant community development plays an important role in the habitat for wild animals; therefore, it is expected to positively impact biodiversity enhancement.
