This research scrutinizes the concept of 'Juchegeonchuk' (self-reliance ideology in architecture), which is a key concept to understand the architecture and urbanism of North Korea in the 1970's and 80's. In the 1970's and 80's, Kim Jong-il began to appear in politics in earnest after Kim Il-sung appointed Kim Jong-il as Kim Il-sung's successor to the next generation. There have been many previous studies about 'Juchesasang' (self-reliance ideology) in various fields, except in architecture. On the other hand, the in-depth research into Juchegeonchuk, which was a method to strengthen Juchesasang, was not good enough in architecture. In this sense, this research investigates the concept of Juchegeonchuk based on the Geonchugyesullon (The Art of Architecture), which embodied the thought of architecture and culture of Kim Jong-il published in 1992. This research scrutinizes the idea of Juchegeonchuk on The Art of Architecture, and its representation in architecture and urbanism in Pyeongyang based on the idea of Juchegeonchuk. It enables to find a new interpretation of North Korea's architecture introduced by Kim, Jong-il in the late 20th century.

In this study, we investigated the characteristics of the analogies, the mapping understanding, and the mapping errors on saturated solution of scientifically-gifted and general elementary students. Fifth graders (n=60) at four scientifically-gifted education institutes in Seoul and/or Gyeonggi province and fifth graders (n=91) at three elementary schools in Seoul were selected and assigned to the scientifically-gifted group and the general group respectively. After the students of each group performed the experiment and were taught about the target concept in the first class, they administered the test on the self-generating analogies on the target concept in the second class. The results revealed that the students in the scientifically-gifted group made more analogies, especially verbal/pictorial, structural/functional, enriched, and higher systematic ones, and had deeper understanding of the analogy than those in the general group. The numbers of the shared attributes included in the student-generated analogies and the scores of the mapping understanding of the students in the scientifically-gifted group were significantly higher than those in the general group. The students in the scientifically-gifted group had fewer mapping errors than those in the general group. However, not a few students in the scientifically-gifted group had at least one mapping error. Educational implications of these findings are discussed.

study investigated the relationship between conceptual understanding and mapping errors induced in learning chemistry concept with two analogies presented in current science textbooks. Each of the two groups from 7th graders (N=260) in three middle schools studied with one of the analogies, and then a conception test and a mapping test were administered. Analyses of the results indicated that students conceptual understanding has a significant relationship with their understanding about the mapping. The scores of the conception test and the mapping test for the unshared attributes were lower than those for the shared attributes. Five types of mapping errors were also identified: overmapping, mismapping, failure to map, rash mapping, and artificial mapping. Many representative misconceptions were found to be associated with their mapping errors. Educational implications are discussed.

Urban planning and engineering undergraduate students need to understand the earth physical systems and that how human beings interact with the earth systems to planning and engineering urban area. The eco-friendly or geo-friendly design and planning of an urban area is a critical issue not only for economic benefits but more importantly for the sustainable future of urban life. However, little study has been done dealing with the urban engineering students' understanding of the earth as a system and what pedagogical approach is appropriate to improve their understanding of the earth as a system. This study is to investigate the impact of a purposely designed ESS course on urban engineering students' understanding of the earth as a system and their perceptions about the instructional approaches of the course on their learning competency. This study utilized a mixed-methodology with three main data sources: concept maps, student's perception survey about their learning competency, and course contents. Both the survey and concept maps were analyzed quantitatively as well as qualitatively. The result of this study showed that the urban engineering students' experience of team-based research about the topic they chose based on their own interest had a positive impact on their understanding of the earth as a system and their learning competency. The results of this study suggest that structuring and presenting the earth system contents in the context of engineering students' understanding and their future career be effective not only for the improvement of students' content knowledge but also for the enhancement of their learning competency such as creativity and problem-solving skills in everyday life situation.

The purposes of this study were grasping the degree of students' understanding for course contents through the concept mapping strategy as meaningful learning in science and measuring the effect for change of conception and changing the misconception. The results of the study were as follows: 1. Before the lesson, only 10.7％ of students had scientific conception of molecular motion. Other students had various kinds of misconceptions. 2. The extent of concept formation after lesson through the using concept mapping strategy was tested. As a result, compared with the controlled group, the experimental group showed higher extent of sound concept formation (statistical significance level 0.05). 3. The differences between the experimental group and the control group were analyzed into quantitative and qualitative points of view. The results of the comparison showed that the maps of the students were well configured in the categories of the relationship, the hierarchy and the examples; while students showed lower abilities in the category of the cross-links. 4. The student's attitudes to ward concept mapping was positive. Most of the students answered that teaching strategy of concept mapping benefits them in meaningful learning outcomes.

The study investigated the effect of a social constructivist model on changes of concept on 103 4th graders in three elementary schools. In particular, it analyzed whether the application of a concept circle map developed student understanding of the concept. After a one month study period, the 103 students took a pencil and paper test on changes of concepts learned. The results indicated that the social constructivist model positively influenced student concept development. In conclusion, a concept circle map used on a social constructivist model may be employed as a tool for diagnostic or formative evaluation.

Purpose: This paper analyzed the historical origins of the Qi concept and assesses its possible contribution to the development of complementary therapy and new nursing practices. Methods: In order to clarify the Qi concept measure its theoretical/clinical potentials, this study analyzed both historical data and experimental research that adopt and apply the concept. These include modern/contemporary research measuring its effects in promoting mental and physical health. Using the method of cross-cultural comparison, this study analyzed diverse approaches to the Qi concept and sought to find common features among the approaches. Results: A historical, cross-cultural analysis revealed several fundamental similarities between Qi theories that have developed in the east and the holistic concepts that have evolved in the western traditions. Especially, the analysis of the more recent research on the Qi concept shows ample possibilities of its future contributions to the development of new diagnostic applications and the promotion of overall human health. Conclusion: The historical study of the Qi concept found some key common factors in the diverse philosophical traditions in the east and the west. Considering the growing popularity of complementary therapy among health professionals and the general public, the Qi concept and its clinical applications are expected to promote human health. In this context, this research contributes to developing new nursing practices based on the concept by clarifying its philosophical origins and theoretical backgrounds.

In this study, the effects of a self-assessment on the students' science concept understanding and science-related attitudes were investigated. Student's perceptions towards the self-assessment were also examined. Five classes from a middle school in Gyunggi Province were chosen. Two of those classes were assigned to the control group that no self-assesment tool was applied to and the other 3 classes were assigned to the experimental group which a self-assess-ment tool developed for this study was applied to. The experimental group was further divided into two groups for imple-ment of two kinds of programs. One experimental group was provided some feedback such as solutions to problems and the other was not provided any type of feedback. The tests of science-related attitudes were administered before and after the instruction period. The science concepts understanding test was done only after the instruction. The results of this study were as follows. There were significant differences between the experimental group and control group in under-standing of scientific concepts. The enhancement of science-related attitudes was also higher for the experimental group. Providing feedback to students was more effective in the improvement of students' science-related attitudes. However, there were no significant differences in understanding of scientific concepts in relation to the feedback in experiment groups. From the above results, it was acknowledged thet self-assessment applied to the middle school science class showed considerably positive influences on the improvements of the understanding of scientific concepts and science-related attitudes.

This study evaluates on students' understanding and misunderstanding of homeostasis, classification of animals and plants, and food production in plants, and analyzes the teacher factor as a possible source of students' misconception. A total number of 863 students and 47 biology teachers at the middle and high school were randomly selected. Students' conceptions and misconceptions were measured with concept evaluation statements (CES) which was translated into Korean by author. The CES was developed and validated by Simson and Marek (1988). Teacher's misconceptions were investigated the way in which teachers marked students' work. The supposed answer given to the teachers to mark was based on misconceptions held by students tested in concept evaluation statements. The results of this study are as follows : 1. 0% of 7th Grade students, 4.5% of 9th Grade students and 5.4% of 11th Grade students understood homeostasis. There was a significant difference at the level of students' understanding of homeostasis according to schools and gender(P<0.05). Many students had a tendency of understanding the conception of the homeostasis by experiences and unscientific use of everyday language rather than a scientific concept. 2. 0.4% of 7th Grade students, 3.1% of 9th Grade students and 2.9% of 11th Grade students understood classification of animals and plants. There was a significant difference at the level of students' understanding of classification of animals and plants according to schools and gender(P<0.05). Students classified animals and plants through personal experiences and observations instead of trying to classify through microscopic analysis of animals and plants cell. 3. 1.2% of 7th Grade students, 10.3% of 9th Grade students and 19.4% of 11th Grade students understood food production in plants. There was a significant difference at the level of students' understanding of food production in plants according to schools and gender(P<0.05). Students had a misconception that food production in plants was done by an absorption of nutrients from soil not by photosynthesis. 4. A large proportion of teachers surveyed in this study appear to have misconceptions about homeostasis (38.1%), classification of animals and plants (34.1%), food production in plants (40.4%). The male teachers had. more misconceptions than female teachers(P<0.05). However, they didn't show any significant differences according to schools and teaching experience(P<0.05). 5. According to the investigation of teachers' perception, 29.8% of the teachers acknowledged that they might be a cause for students' misconceptions. This study shows that 38.3% of teachers did not understand the analyzed biological concepts precisely. By comparing the data of students and teachers, it turned out that teachers participate in the students' misconceptions. And teachers themselves acknowledged that students' misconceptions could be caused by them. Therefore. teachers' right understanding of fundamental biological concepts should precede to students' biology education. New training programs for biology teachers seem to be urgent.
