The feasibility of integrated concepts as a key element in designing integrated science curriculum has been investigated by analysing science contents included in performance expectations stated at different grades. The science curriculum of Singapore and the state of Ontario in Canada, and next generation of science standard (NGSS) were selected. Each of them presents theme, fundamental concepts, and crosscutting concepts, which has the characteristics of integrated concepts proposed in the study. Analysis showed that theme, fundamental concepts, and crosscutting concepts were influenced by the characteristics of each curriculum. In addition, science contents related to integrated concepts at different grades varied with the nature of integrated concepts. Based on results, some suggestions were made. First, the total number of integrated concepts should be considered for designing integrated curriculum. Second, the nature of integrated concepts and science contents associated with the integrated concepts should be considered. The integrated concepts should be vast and deep enough in the meaning to contain various content knowledge of different science domains. Third, it should be considered that how the integrated concepts have to be presented at different grades.

Integrated concepts that are broad enough to embrace facts, principles, laws, and concepts of multiple disciplines could become the core of integrated education. Integrated concept-centered education enables effective and practical learning. In this study, the Delphi Method was implemented targeting experts in science (physics, life science, chemistry, and earth science) and humanities (history, geology, economics, ethics, and politics) to find out the integrated concept that can be used to design the concept-centered integrated education in the Republic of Korea. 124 experts participated in this survey. Delphi survey was conducted for three rounds. In the first round, an open questionnaire was given to experts to collect feasible integrated concepts in each major field. Then, in the second round experts were asked to select integrated concepts that could be used practically in the field of their major. In the third round, the integrated concept with selection frequency over medium value were given. They were asked to evaluate the applicability of integrated concepts by using the Likert-scale questionnaire. Through this process, content validity was analyzed. As a result, five integrated concepts (change, interaction, space-time, energy, and equilibrium) were selected for the inter-science integration. And thirteen integrated concepts (conflict, community, relationship, structure, power, diversity, culture, change, society, interaction, freedom, justice, and equality) were chosen for the inter-humanities integration. Finally, for the science-humanities integration, seven integrated concepts (structure, diversity, change, interaction, cycle, system, and environment) were determined.

In this study, concept centered approach and process centered approach in developing integrated science curriculum were compared and compromised between two approaches. It seems that two approaches are in antagonistic relations. The superficial conflictions getween two approaches are not because they are antagonistic in their nature, but because their interesting points are different. The concept centered approahc is interest in fundamental scientific concepts and the process centered approach is interested in scientific enquiry. If science is the composition of enquiry processes and concepts produced by enquiry processes, scientific enquiry process and scientific concept must not be inconsistant. Although concepts are not unchangeable, new concepts and advanced concepts are based on the old concepts. Enquiry activity which is not based on concepts also cannot be significant enquiry. Although fundamental concepts in science is very important, in order to apply concepts to varios phenomena, and to understand concepts more deeply the student should understand concept through the process by which the concepts are derived. As we have discussed above, only the concept centered approach or the process centered approach itself is not complete. Comparing these two uncomplete approaches to integrated science curriculum, we can find out that two approaches are in complementary relations. Because integrated science is based on the idea that natural phenomena should not be understood in fragments, but should be understood as mutually related system' the integrated science curriculum includes both the fundamental scientific concepts and scientific enquiry processes.

Science has an essentially integrated character as a discipline that explores the natural phenomena. And the integrated science education is required to achieve the goals of science education to forster scientific literacy of all students. In this respect, we defined the basic concepts and principles that can penetrate the natural phenomena as an integrated concepts in this study, and organized the contents of integrated science curriculum around them. Integrated concept centered curriculum was intended for the 10th grade students and the breadth and depth of learning concepts were represented by presenting the achievement level of the learning concepts. Contents organization of integrated science curriculum presented in this study was meant to provide a new perspectives to the revision of the national integrated science curriculum that is currently in progress.

The purpose of this study was to develop an integrated music activity model based on musical concepts for 2-year-old children in order to include music in whole personality education in a rapidly changing society with increasing need for toddler care. Research methods were review of literature and survey. Subjects were 185 teachers in B city. They were asked to record their thoughts and needs during the process of musical activities with toddlers. Research concluded that an integrated music activity model for toddlers requires statement of purpose, contents based on musical concepts, and appropriate teaching methods which can be extended to arts education in general. Discussion further suggested diverse expression through singing, listening, body movement and combining with other arts.

This paper discusses the strategic concepts applied to integrated delivery system(IDS). IDS is rooted in vertical integration(VI) and strategic alliance(SA), but only few knows about the theoretical backbone of the IDS. The paper explains how VI and SA applies to IDS, then provides cases of IDS rooted in strategic concepts; Kaiser Permanante Model, Mayo Clinic Model, and ACO(Accountable Care Organizations). Finally the paper provides the implication of IDS on Korean healthcare delivery system.

This study aims to find an effective way to present essential science concepts in national science curriculum through international comparisons. Next Generation Science Standard (US), Ontario Science Curriculum (Canada), Australia Science Curriculum, and British/English Science Curriculum were selected for comparison. In science curriculum documents, these countries used terms such as 'Key ideas,' 'Big ideas,' 'Key concepts,' 'Disciplinary core ideas.' and 'Fundamental concepts' to present essential concepts of science. This study reviewed the characteristics of the meaning, the status, and the role of essential concepts country by country. The result shows essential concepts have been used with different meanings and statutes in each case. Furthermore, various roles were performed through essential concepts in order to organize their science curriculum. From these foreign nation's cases, this study proposes several ways to present essential science concepts based on results. First, interdisciplinary integrated concepts were needed to organize an integrated science curriculum. In science curriculum documents of the United States, Canada, Australia and England, two types of terms were used in order to structuralize an integrated science curriculum. Second, essential concepts should include concepts related with function and value as well as scientific knowledge. Third, essential concepts need to be presented in such a way as to show specific contexts. Therefore, selecting appropriate contents and structure are needed to be able to improve the way to present essential concepts in Korea's educational environment.

An entity-based integrated design product and process model uses product and process entities to describe design information and design activities, respectively. The concepts and notation for product and process entities in the entity-based integrated design model are similar to the concepts of object-oriented programming languages such as C++ and Smalltalk. This paper uses C++ to program an entity-based integrated design model for building frames structures. The design information and activities involved in the three dimensional building space, the locations of frames, and the grouping of frames represented as entities in the entity-based integrated design model are transformed to C++ codes. Each product or process entity can be basically transformed to an class. The attributes of an entity can be defined as variables and member functions of a class.

The purpose of this study is to confirm the possibility of whether learning using a math learning platform can be used to expand students' conceptual structure and to consider how to use it. To this end, first-year middle school students studied using a math learning platform. Then, the concept map created was compared and analyzed with the concept map created before learning to examine the change in the concept structure. The results of analyzing the concept map are as follows. First, the change in the hierarchical structure of the concept appeared as the division of the upper concept was subdivided. However, it has also been changed to comprehensively integrate and simplify higher concepts. The term-centered concept structure has changed to content-centered superordinate and subordinate concepts. In the concept structure, subordinate concepts linked to one higher concept were expanded and differentiated. Second, changes in the integrated structure did not form a linkage structure. The expansion of the integrated structure of concepts through learning using the learning platform was influenced by the composition of the learning contents designed in the learning platform.
