In the TIMSS assessment goal and open TIMSS 2007, Singapore recorded a lower overall achievement level compared with Korea; however, the excellent results shown by Singapore furnished an opportunity for various countries to research into the education in Singapore. This paper conducted a comparative analysis of the "Proportion, Proportional Expression, and Percentile" area out of the three topics involving "Fractions and Decimals", "Proportion, Proportional expression, and Percentile", and "Measurement", in all of which Singapore exhibited a higher percentage of correct answers than Korea. The paper was able to discover the following differences through a comparative analysis of how Korean and Singaporean textbooks deal with the open questions of TIMSS 2007 after looking into them according to four assessment goals. First, the Singaporean textbook introduced the concept of proportion one year ahead of the Korean textbook. Second, the Singaporean textbook repeatedly coped with the topic of "Proportion, Proportional Expression, and Percentile" in depth and by academic year, and its volume was larger than that of the Korean textbook. Third, there was a difference in the introduction and definition of the concept of proportion. Fourth, the way of introducing a proportional expression was also different, and the Singaporean textbook proposed many more questions that utilize this expression in ordinary life. Based on these differences, the paper suggested implications that could be applied to the Korean curriculum and textbook.
A Discourse Analysis tool has been developed and has been applied in the cooperative group inquiry activities in order to derive the characteristics of elementary gifted students in science. We recorded and videotaped the whole group problem-solving processes where 4 elementary students worked together to solve given problems as a group for one year in a gifted education center attached to a university in Seoul. We analyzed recorded discourses using systemic functional linguistics with a focus on the structure of information and topic. The discourse analysis tool was developed with the cooperation of science education and gifted education experts. In discourse analysis, we focused on meaning development processes rather than grammatical analysis. Through application of newly developed discourse analysis tool, we confirmed that the tool is useful in understanding the characteristics of science-gifted elementary students. We also founded that the interaction between students has significant effects on problem-solving processes by comparing two students who showed contradictory features in the share of dialogue. In addition, the result suggested that we need to provide students with proper training for ways to communicate with others for effective science-gifted instruction.

This study analyzed the evolutionary content in 13 textbooks developed from the first to the 6th high school biology curriculum, The content analysis of textbooks, which were delineated nine component, was performed on the 80 evolutionary categories, According to the result, the proportion of the total evolutionary content in textbook increased from the textbooks developed by the Ist curriculum to the textbooks developed by the 6th curriculum, but the proportion of 'main narrative' in total evolutionary content was gradually decreased. It also showed that biology curriculum and points of view of textbook writers influenced on the proportion of evolutionary contents. On the whole, the topics of analysed textbooks exhibit insufficient diversity, Any categories- 'group selection', 'gene selection', 'gaps in fossil record', 'co-evolution', 'punctuated equilibrium', 'mosaic evolution', 'place of labor in human evolution', 'human race differentiation', 'criticism of "ontogeny recapitulates phylogeny", and 'human activities affecting evolution' - were not treated and others - 'theory of neutralism', 'theories of major episodes(excepting extinctions) found in the geologic time scale', 'sympatric speciation', 'clinal and area-effect speciation', 'polyploidy and evolution', 'gradualism' and 'evolution and origin of mammals' - were treated very lightly, the most emphasized topic was 'phylogeny in general' and 'formation of precells', 'miscellaneous' in the order of emphasis. 'Theory of natural selection' was lightly treated as just one of evolutionary theory though it should be emphasized as major theme of evolution. Also, the law of recapitulation, of which biologists doubt the validity, was discussed as an evidence of evolution in some textbooks. And the agents of genetic equilibrium disruption like genetic drift and migration were treated as of little importance. On the basis of above result, it was suggested that the textbook writers introduced the more meaningful evolutionary topics focused the theory of natural selection in explanation of evolution and evolution theory.
This paper reviews the topic of GIS, the academic setting of GIS, GIS model curricula and the possibility GIS education in Korea. The topics which might be included in a science of geographic information consist of data collection and measurement, data capture, spatial statistics, data modeling and theories of spatial data, data structures, algorithms and processes, display, analytical tools, institutional, managerial and ethical issues. The problems in teaching a course on GIS in higher education are reviewed. Because of their technological, integrative, and rapidly changing nature, GIS pose major challenges to their education system which it is ill equipped to meet. In higher education a number of initiatives have been taken to provide education about and training with, GIS. The possible GIS curricula are suggested. These curricula are divided into 3 major sections, relating GIS context, technical issues and application issues. The prospects of GIS appears lo depend largely upon the future cooperation of academia, government, and industry
Introduction This study is concerned with improving the nursing education curriculum. The purpose of the study was to 1. Review the basic principles of curriculum development. 2. Determine opinion about current nursing curriculums from recent nursing school graduates. Methods of the study A questionnaire was distributed to 250 nurses, in f general hospitals in Seoul. The nurses were graduated from nursing schools in 1973, but represented all types of nursing programs. The Questionnaire was designed to illicit responses about nursing school curriculums in 5 areas: 1. Establishment of objectives 2. Selection of learning experience 3. Organization of learning experience 4. Instruction 5. Evaluation Summary of the major findings 1. Establishment of objectives Thirty nine point three percent of the nurses said that the first objective of the general nursing education was stated "to educate a nurse as a human being with humanity:" Ninety point eight percent of the total respondents said that thor knew the objectives of the curriculum of their nursing schools, but more half of them (58.3%) understood the objectives vaguely at the time they attended nursing school. 2. Selection of learning experience Thirty nine point eight percent of the respondents said their curriculum contained "only a few" liberal arts courses. 3. Organization of learning experience forty seven point six percent. of the respondents were reported that the number of course hours was "insufficient" in liberal arts courses. Fifty seven point three percent of the nurses felt there was an overemphasis on any special topic in liberal arts courses. 4. Instruction Methods of instruction were as follows: Liberal arts courses-a. lecture which centered on explanation (61.1%), b. lecture which centered on writing (43.7%) Supporting nursing courses-a. lecture which centered on explanation (34.0%). b. laboratory Practice (37.8%) Clinical nursing courses-a. lecture which centered on writing (33.0%), b. clinical practice (38.4%) The percentage of respondents replying that various equipment for the learning activities were "insufficient"were as follows: Liberal arts courses-51.0% Supporting nursing courses-28.6% Clinical nursing courses-37.9% 5. Evaluation In the liberal arts courses, 30.6% o( the respondents answered that the evaluation of records was in their opinion "poor, " and 28.2% of the respondents reported that the method of evaluation was "unfair and discouraging. " "Development of a systematic theory of nursing" was thought to be essential for curriculum improvement. The respondents felt that the junior year was the hardest because 1. Number of subjects was too great (28.1%) 2. Lack of a systematic theory of nursing (14.5%) 3. Conflict due to the difference between nursing theory and nursing practice (21.4%) Recommendations 1. Since this study was limited to nurses who had graduated in 1973, a larger study involving professors, graduate students, and nurses from a wider area is suggested in order to establish the reliability and validity of the present findings. 2. Nursing research should be carried out more actively in order to develope nursing science. 3. A permanent organization for research into ways to improve the curriculum should be established in each nursing school.
The purpose of this study was to examine the awareness of dental hygienists, who played a significant role in dental sector, about health care management and their needs for education in an attempt to pave the way for the development of a Dental Hygienist Coordination System(DHCS). The subjects were 156 dental hygienists at 85 dental clinics, who were selected in Gwangju based on the data released as of August 2008 by the Dental Association and public health centers in sampling region. A Questionnaire was conducted in person to gather survey data and SPSS 12.0 program was utilized to make a statistical analysis. This results findings suggested that a systematic curriculum should be developed by focusing on coordination theory and practice, counseling and educational practice, health insurance affairs and health insurance fee claim management.
Mitophagy, a cellular process that selectively targets dysfunctional mitochondria for degradation, is currently a hot topic in research into the pathogenesis and treatment of many human diseases. Considering that hypoxia causes mitochondrial dysfunction, which results in cell death, we speculated that selective activation of mitophagy might promote cell survival under hypoxic conditions. In the present study, we introduced the Regulator of calcineurin 1-1L (Rcan1-1L) to initiate the mitophagy pathway and aimed to evaluate the effect of Rcan1-1L-induced mitophagy on cell survival under hypoxic conditions. Recombinant adenovirus vectors carrying Rcan1-1L were transfected into human umbilical vein endothelial cells and human adult cardiac myocytes. Using the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay and Trypan blue exclusion assay, Rcan1-1L overexpression was found to markedly reverse cell growth inhibition induced by hypoxia. Additionally, Rcan1-1L overexpression inhibited cell apoptosis under hypoxic conditions, as detected by annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) apoptosis assay. Meanwhile, the mitochondria-mediated cell apoptotic pathway was inhibited by Rcan1-1L. In contrast, knockdown of Rcan1-1L accelerated hypoxia-induced cell apoptosis. Moreover, Rcan1-1L overexpression significantly reduced mitochondrial mass, decreased depolarized mitochondria, and downregulated ATP and reactive oxygen species production. We further delineated that the loss of mitochondrial mass was due to the activation of mitophagy induced by Rcan1-1L. Rcan1-1L overexpression activated autophagy flux and promoted translocation of the specific mitophagy receptor Parkin into mitochondria from the cytosol, whereas inhibition of autophagy flux resulted in the accumulation of Parkin-loaded mitochondria. Finally, we demonstrated that mitochondrial 1permeability transition pore opening was significantly increased by Rcan1-1L overexpression, which suggested that Rcan1-1L might evoke mitophagy through regulating mitochondrial permeability transition pores. Taken together, we provide evidence that Rcan1-1L overexpression induces mitophagy, which in turn contributes to cell survival under hypoxic conditions, revealing for the first time that Rcan1-1L-induced mitophagy may be used for cardioprotection.

The purpose of this research was to develop the education program on traditional living culture for home economics(HE) based on the 2015 revised national curriculum. The existing school curriculum for traditional living culture tends to overly focus on the theories about traditional culture and suffer from absence of continuity in learning activities. It can be argued that HE is an ideal subject for dealing with traditional living culture as it aims to develop students' ability to recreate the traditional culture, meeting present needs and trends. This study, thus, attempted to present the practical ways of improving the quality of education on traditional living culture by developing HE education program for high school students. To fulfill the purpose, this research, as a teaching topic, selected the traditional patterns and the "Obangsaek"(Korean traditional five colors) which can commonly be dealt with in the subjects of traditional Korean food, Korean costume and Korean style house. In particular, the program was developed following the ADDE process. In the stage of analysis, this article analyzed the HE curriculum and making activities included in HE textbooks based on the 2015 revised national curriculum, as well as the needs of teachers and students regarding traditional living culture education. In the stage of design, this study developed the instructional model, selecting class topics, tools and materials. In the stage of development, the programs on traditional living culture including costume, food and house were developed. In the evaluation phase, this research conducted the validity test and received the feedbacks from 12 HE educators in order to complete the programs. This study finally suggested that future studies in this area examine the effect of the presented programs on enhancing the students' perception of traditional culture and the will of developing and succeeding the traditional living culture.

In the context of region reconceptualized as a learning framework, using the Seoul region as an example, this paper focused on the debate and the condition of regional social studies curriculum in elementary schools, It means that regionalization of curriculum is the decentralization of power to develop and manage curriculum In that case, region is understood to he a resource used to connect the subject matter to children's experience, Furthermore, region is interpreted as Heimat, community and world around, Heimat is intended to be understood, loved and belonged to, Community is the resource for learning and the space of communication, participation and action, World around is the typical example to be searched, compared and explained by the concept and theory. On the base of the regionalization debate and the classification of learning a region, I analysed the local textbook, Social Studies Inquiry: Life in Seoul and suggested the framework of learning a region. In this paper, I tried to pick out the spatial demension of Seoul. It is classified into the space of experience, participation and inquiry, In conclusion, the region-specific materials and approach laying stress on the issue and topic in the geographical context of the region will determine that a proper regionalization occurs through not only methods hut also content.
The documentation of a city can never be complete with only the documentation of the administrative domain, and requires that of its citizens, who are living in the city in different ways. This study attempts to present the documentation of the memories of the citizens, which either have never been produced or have been damaged and thus are difficult to be collected. From the Archival Activist point of view, this study suggests documentary as its research method, in order to leave trace of various experiences of Seoul, which are not recorded in document but are rooted in its people's memories and their daily lives. Documentaries are characterized by their narrative. This can be somewhat arbitrary, but it is due to their narrative that this study suggests documentaries, rather than oral statements, as a new form of method. While, due to its self-historicality, oral records are subject to producing redundant or irrelevant memories, documentaries enable the documentation of data relevant to the topic of collection. First, the study presents the narrative-based archiving, which is the same method of collection suggested by Seoul Metropolitan Archives, and then explores the role and significance of documentary archiving. It further presents the conditions in which documentary archiving is required in the context of narrative-based collection. The study presents the planning and implementation of documentary archiving and introduces one of the three documentaries produced by 2019 Seoul Archiving Project.
