  • In order to succeed to the 'Traditional Play Series 1~9' by Prof. Sa Jinsil, this article sought the contact points between the traditional drama and the elementary drama education that Prof. Sa Jinsil held. The educational perspective of the prof. Sa Jinsil is reflected specifically in the seventh and eighth volumes. However, these educational perspectives are similar to those presented in the 2015 revised curriculum. It is also similar to the cultivation of humanities through theater education. In other words, the similarity is confirmed in that the target is creativity-interdisciplinary type human. The foresight of the prof. Sa jinsil in the education for creativity-interdisciplinary type human is confirmed. On the other hand, in order to cultivate creativity-interdisciplinary type human, it is also required to cultivate the ability to 'fun speaking' as well as 'logically speaking'. In this regard, I presented Jaedam, one of the Korean traditional plays, as an alternative. The reason for this is as follows; (1)It is possible to succeed Korean traditional theater performance style through regular class. (2)Students can develop emotional and empathy skills through fun speaking education. (3)Students will develop persuasive storytelling skills. At this time, the traditional play series 1~9, which contains the works of Prof. Sa Jinsil, and cultural ideas and educational ideas, will be useful.

  • The goal of this study was to apply an expectancy-value model(Wigfield & Eccles, 2000) to explain changes in six multi-ethnic students' achievement motivation in mathematics during sixth (2012) to eighth (2014) grades. In order to achieve this goal, we used narrative research methods. Although individual students' achievement motivation and mathematics related life experiences differed, there are some common factors influencing their motivation development, especially (a) roles played by parents and teachers; (b) assessment of peers' competencies; (c) past learning experiences related to mathematics curriculum; (d) perception of the relationship between mathematics competency and other subjects; (e) home backgrounds; and (f) perceived task values. In this study, we achieved some insight into why some multi-ethnic students are willing to study hard to get good scores while others are uninterested in mathematics, and why some multi-ethnic students are likely to pursue new mathematical tasks and persist despite challenges, while others easily give up studying mathematics in the face of adversity. We argue that in order to increase and sustain multi-ethnic students' achievement motivation, educators and parents should recognize that motivation is contextually formulated in the intersection of current people, time, and space, not a personal entity formed in an individual's mind. The findings of this study shed light on the development of achievement motivation and can inform efforts to develop multi-ethnic students' positive motivation, which might influence their mathematics achievement and success in school.

  • The purpose of this study is to analyze the operating case of admission officer system of colleges and universities in USA, and to deduce its implications to Korean colleges and universities. In order to accomplish the purpose of this study, following methodologies were adopted: review on the related literatures, statistical data, and previous studies concerning admission officers of colleges and universities in USA, and in-depth interview with them. Historical and cultural background of university admission system of USA was analyzed. Case study on USA colleges and universities was divided with four parts such as determining factors of admission and admission methods, organization for admission affairs and its number of persons, work of admission officer and admission process, and cost of admission and salary. Implications to Korean colleges and universities were presented with three points such as overall implication, implication on materials for admission process, and implication on managing system of admission. Based on the analysis, discussion and implications, the conclusion and further suggestion of this study are as follows: First, actual authority of admission should be grant to admission officer. Second, not only non-curricular factors but also scholastic factors should be emphasized in role of admission officer. Third, education and training about work of admission officer and unification of criteria for admission should be held. Fourth, admission officers with various occupation background are needed. Fifth, work of admission officers should be extended to various work concerning university entrance. Sixth, cross-checking on marks of over two admission officers is needed. Seventh, in order to stabilize admission process, status of admission officer should be stabilized. Eighth, part-time admission officers are need to employ in season of admission. Ninth, authority of weighting high schools should be grant to admission officers in long term perspective.

  • Great Dharani Sutra of Undefiled Pure Light (Gwi) (LKH 10703) donated by the family of the late Lee Kun-Hee to the National Museum of Korea in 2021 is a calligraphy album consisting of sixty-two leaves compiled using butterfly binding. It contains Great Dharani Sutra of Undefiled Pure Light, "Record of the Production of Mugujeong Pagoda by the Order of King Munseong," a postscript by Kim Jeonghui, and an appreciation record by Oh Sechang. This paper has revealed that this album is identical to the material that Suematsu Yasukazu introduced in Volume 15 of the journal Cheonggu hakchong in 1934 and that it includes elaborate copies of Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" on yellow Chinese paper, both of which were excavated from inside the Mugujeong Pagoda at Changnimsa Temple in Gyeongju in 1824. It has also reconfirmed that it is highly probable that the Great Dharani Sutra of Undefiled Pure Light that Jo Byeongsun, the former director of the Seongam Old Books Museum, unveiled in 1998, is a transcription of the original sutra excavated from Mugujeong Pagoda at Changnimsa Temple in Gyeongju. Moreover, it has concluded that the Great Dharani Sutra of Undefiled Pure Light owned by Park Cheolsang is likely to be another example of copying the transcription of the original sutra excavated from the Mugujeong Pagoda at Changnimsa Temple in Gyeongju. In the album of copies donated by the estate of Lee KunHee, six of the Chinese characters promulgated by Empress Wu were used fifteen times in total. Four of the characters of Empress Wu were utilized ten times in the Great Dharani Sutra of Undefiled Pure Light (national treasure, Bulguksa Temple collection) found among the reliquaries from the Three-story Stone Pagoda at Bulguksa Temple in Gyeongju and were also seen in the album of copies donated by the estate of Lee Kun-Hee. The use of the same characters of Empress Wu and other variant characters suggests that both the album of copies donated by the estate of Lee Kun-Hee and the Bulguksa sutra were based on an edition distributed in the Unified Silla Period during the eighth century. Kim Jeonghui confirmed the exchange of calligraphy between Korea and China through studies on bronze and stone epigraphs. He believed that the Great Dharani Sutra of Undefiled Pure Light and "Record of the Production of Mugujeong Pagoda by the Order of King Munseong" excavated from Mugujeong Pagoda at Changnimsa Temple were authentic materials showing the elegant calligraphic styles that prevailed before the Ouyang Xun style. Thus, the album of copies donated by the estate of Lee Kun-Hee holds great historical and artistic significance in that it is a rare example of Kim Jeonghui's evidential study of a transcribed sutra and an original record of the production of a pagoda from the Unified Silla period.

  • Rapid industrial growth based on massive fossil fuel energy consumption has caused serious damages on natural environment and every aspects of human life. As demands for clean and pleasant living circumstance increases, conflicts and disputes around environmental problems have also been widespread. Given the 'environmental rights' is a relatively new legal concept, however, resolving environmental disputes through the traditional legal principles and litigation procedures could be restrictive and, in some sense. inefficient as well as expensive. With efforts to develop new legal principles on environmental disputes, the environmental dispute adjustment system has been introduced as an alternative dispute resolution to the traditional legal dispute procedures. The Korean Environmental Dispute Resolution Commission introduced as the environmental dispute adjustment system has been well established for the past twenty-seven years, given the steadily increasing numbers of applications to the Commission over environmental disputes. However, as most cases are still small in money terms and mainly subject to adjudication, the effectiveness and practical contribution of the Commission in the resolution of environmental disputes have in fact been limited. For the enhancement of the status and roles of the Commission as the prior instrument of the alternative dispute resolution(ADR) in environmental disputes, several suggestions could be considered as follows: First, mediation needs to be more activated than adjudication in order to meet the primary purpose of ADR that resolves environmental disputes according to free will of concerned parties. Second, the scope of mediation could be expanded to the areas including potential environmental damages. Third, the roles and responsibilities of the Environmental Dispute Resolution Commissions at both central and local levels need to be evenly distributed. Fourth, the mechanism and procedures of environmental dispute resolution should be standardized. Fifth, the status of the Environmental Dispute Resolution Commission could be elevated in rank by shifting its current affiliation from the Ministry of Environment to the Office of Prime Minister. Sixth, the organizational structure and human resources of the Commission need to be reinforced. Seventh, the current situation that tends to give priority to litigation procedures when an environment dispute is simultaneously pending in litigation and mediation should be eased and properly adjusted. Eighth, the adoption of mandatory mediation in advance to litigation needs to be discussed. Ninth, the legal authority of the Commission's decisions should be further guaranteed. If above suggestions are thoroughly reviewed and properly adopted, the roles, authority and power of the Environmental Dispute Resolution Commission would be increased in the era when environmental conflicts get widespread, requiring an effective alternative environmental dispute resolution mechanism.

  • The pikromycin biosynthetic system in Streptomyces venezuleae is unique for its ability to produce two groups of antibiotics that include the 12-membered ring macrolides methymycin and neomethymycin, and the 14-membered ring macrolides narbomycin and pikromycin. The metabolic pathway also contains two post polyketide-modification enzymes, a glycosyltransferase and P450 hydroxylase that have unusually broad substrate specificities. In order to explore further the substrate flexibility of these enzymes a series of hybrid polyketide synthases were constructed and their metabolic products characterized. The plasmid-based replacement of the multifunctional protein subunits of the pikromycin PKS in S. venezuelae by the corresponding subunits from heterologous modular PKSs resulted in recombinant strains that produce both 12- and 14-membered ring macrolactones with predicted structural alterations. In all cases, novel macrolactones were produced and further modified by the DesVII glycosyltransferase and PikC hydroxylase leading to biologically active macrolide structures. These results demonstrate that hybrid PKSs in S. venezuelae can produce a multiplicity of new macrolactones that are modified further by the highly flexible DesVII glycosyltransferase and PikC hydroxylase tailoring enzymes. This work demonstrates the unique capacity of the S. venezuelae pikromycin pathway to expand the toolbox of combinatorial biosynthesis and to accelerate the creation of novel biologically active natural products. The polyketide backbone of rifamycin B is assembled through successive condensation and ${\beta}$-carbonyl processing of the extender units by the modular rifamycin PKS. The eighth module, in the RifD protein, contains nonfunctional DH domain and functional KR domain, which specify the reduction of the ${\beta}$-carbonyl group resulting in the C-21 bydroxyl of rifamycin B. A four amino acid substitution and one amino acid deletion were introduced in the putative NADPH binding motif in the proposed KR domain encoded by rifD. This strategy of mutation was based on the amino acid sequences of the corresponding motif of the KR domain of module 3 in the RifA protein, which is believed dysfunctional, so as to introduce a minimum alteration and retain the reading frame intact, yet ensure loss of function. The resulting strain produces linear polyketides, from tetraketide to octaketide, which are also produced by a rifD disrupted mutant as a consequence of premature termination of polyketide assembly. Much of the structural diversity within the polyketide superfamily of natural products is due to the ability of PKSs to vary the reduction level of every other alternate carbon atom in the backbone. Thus, the ability to introduce heterologous reductive segments such as ketoreductase (KR), dehydratase (DH), and enoylreductase (ER) into modules that naturally lack these activities would increase the power of the combinatorial biosynthetic toolbox. The dehydratase domain of module 7 of the rifamycin PKS, which is predicted to be nonfunctional in view of the sequence of the apparent active site, was replaced with its functional homolog from module 7 of rapamycin-producing polyketide synthase. The resulting mutant strain behaved like a rifC disrupted mutant, i.e., it accumulated the heptaketide intermediate and its precursors. This result points out a major difficulty we have encountered with all the Amycolatopsis mediterranei strain containing hybrid polyketide synthases: all the engineered strains prepared so far accumulate a plethora of products derived from the polyketide chain assembly intermediates as major products instead of just analogs of rifamycin B or its ansamycin precursors.

  • The main objective of the study is to propose the most efficient SWAT model calibration method using SWAT-CUP with less computing time and high performance. In order to achieve the goal, Case1-3 (250, 500, and 1,000 simulation runs) and Case4 (1,000 simulation runs in the first iteration and then 500 simulation runs for the following iterations) were defined to compare the results. When evaluating the values of the objective function, Case2 and Case3 reached the same value after the fourth iteration, and Case1 reached the closed value of Case2-3 after the eighth iteration. However, the final estimates of the parameters had different ranges in Cases1-3, and only the results of Case3 and Case4 converged similarly. Thus, it can be considered that the parameter calibration results are highly affected by the initial number of simulation runs. On the other hand, SWAT simulation results did not show the significant difference after the first iteration, unlike the parameter ranges. From the analysis results, we can conclude that the most suitable and effective method was to repeat one or two times of iterations with a sufficient number of simulation runs, as in Case4.

An Analysis of Systems Thinking Revealed in Middle School Astronomy Classes: The Case of Science Teachers' Teaching Practices for the Unit of Stars and Universe (중학교 과학 천문 수업에서 나타나는 시스템 사고 분석: 별과 우주 단원에 대한 과학 교사의 교수 실행 사례)

  • The purpose of this study was to analyze system thinking revealed in science teachers' teaching practices of middle school astronomy classes. Astronomy lessons were video-taped from four eighth grade science teachers. The video recordings were all transcribed and analyzed by employing a framework for systems thinking analysis after modifying an existing frame of hierarchial structure used in relevant previous studies. In addition, four participants were interviewed in order to uncover their orientation toward teaching using video stimulated recall method. Findings are as follows: All participating teachers were not able to employ the four levels of system thinking appropriately and only utilized the low level of systems thinking. They also demonstrated teacher-centered practices for employing system thinking despite their student-centered orientation toward teaching. The main reason for these results may be that teachers focused more on spatial thinking, than on system thinking as well as the lack of teacher's knowledge about the content and formative assessment of non-earth science teachers. Implications on how to effectively employ the system thinking in astronomy class are discussed in this paper.

  • The purpose of this study was to compare the earth science curriculums of South Korea and North Korea. Aspects such as the content of the curriculums and the timing of learning were analyzed, in order to provide basic data that can be used to design a revised and integrated Korean curriculum. The objects of this study were South Korean Science textbooks from grades 5-9, and the high school Unity of Science and Earth Science I and II textbooks. Additionally, from North Korea, the junior middle school Natural Science 1 and 2 textbooks and the senior middle school Chosun Geography 2 and Geography 1 textbooks were analyzed. The results of this study obtained through an analysis that used the Trends in International Mathematics and Science Study (TIMSS 2019) grade 8 earth science assessment framework were as follows. First, South Korea needs to adopt iterative learning. Repetitive learning, which is effective for understanding what is being learned, is applied to only 1 by 8th grade. Second, South Korea needs to adjust the time when certain content is learned. This is because there is a disparity between when content is learned in comparison to North Korea, and the timing of learning of about 50% of the TIMSS standards have not been followed. Third, it is necessary to reflect the content present within the TIMSS that have not been learned. This can be a way to increase the nations' educational competitiveness in the international community. This paper proposed a comparative analysis of South korean and North Korean approaches to the earth science curriculum and conducted practical research to facilitate the construction of an integrated curriculum.
