Open education has brought about new concept and variation in educational quality , schools have adopted open education since mid 1980s. Since then ,open education has developed in Korea, but do not fit to the Korean educational situation without some modification in educational space. In the study, some theoretical backgrounds of open education reviewed from some literature were applied, and introduced the flexibility of the open education, some results of the analysis of flexibility space and furniture system. The purpose of this study is to suggest some of direction in the open education space for more advanced Korean education situation.

This study is to explain understanding types about the concept of a 'Region' in the 3rd grade high school students(39) through open-ended questionnaires and describe the pedagogical utilizations for this. Students' understanding types about the concept of a 'Region' are compared and then determined through two meaning agreement and association between meaning of students' understanding which is collected through open-ended questionnaires and meaning of a 'Region' which is described in high school curriculum. The results are as in the following. First, Students' understanding types about the concept of a 'Region' were divided into four categories: full, partial, ambiguous, and converted understanding. Second, The degree of right meaning agreement and association existing between two meanings is rising steadily by converted, ambiguous, partial, and full understanding. For this reason, This result can make sure the understanding degree about the concept of a 'Region' is different depending on the students. Third, Students' partial understanding, ambiguous understanding and converted understanding on region concept could be judged as misconception not fully corresponded to region concept in the curriculum explanation. Fourth, Teachers can achieve conceptual change through this misconception as a subject matter of educational dialogue for meaning change.

In this paper, we introduce the concept of fuzzy ${\gamma}$-quasi open sets which are generalizations of fuzzy ${\gamma}$-open sets, and obtain some basic properties of such fuzzy sets. Also we introduce and study the concepts of fuzzy ${\gamma}$-quasi continuous mapping and fuzzy ${\gamma}$-quasi open(closed) mapping.

According to the complexity and the pluralism of the modern cities, they are changing themselves into the multinoded and social - classless urban environments. The sudden drift of population to the cities is giving rise to the serious environmental problems, and the rapid increase of recreational needs among the citizen is changing the urban society into a leisure - oriented one. In order to coping with the abrupt change in the social and natural urban environments, the various fields of urban society should be co - ordinated. The study uses the green - city concept to get solves the incongruity of urban structure in Chonju City. The existing open space maps were drawn up by the various techniques such as the analysis of the topographic maps and collected data, the interpretation of the aero-photographs and the reconnaissance of site. The authors suggested the existing condition, and the problems and potentials of open space elements in Chonju City through the analysis of the existing condition maps. After synthesizing the contents of analysis, the 7u(hors established an exclusive open space system for Chonju City.

The wave concept iterative procedure (WCIP) is used to analyze a quasi-square open metallic ring frequency selective surface (FSS). The quasi-square open metallic ring FSS is dual-polarized. When the incident plane wave is polarized in a direction parallel to the FSS' coupled parallel strips, it shows two rejecting bands. Moreover, another rejecting band can be obtained if the source plane wave is perpendicularly polarized with respect to the FSS' coupled parallel strips. The three resonant frequencies are inversely proportional to the length of the FSS' coupled strips to provide an easy fine tuning of the FSS structure. The simulated results obtained using WCIP are compared to the measured results, and a good agreement is reported.

We introduce the concept of fuzzy $r$-minimal ${\beta}$-open set on a fuzzy minimal space and basic some properties. We also introduce the concept of fuzzy $r-M$ ${\beta}$-continuous mapping which is a generalization of fuzzy $r-M$ continuous mapping and fuzzy $r-M$ semicontinuous mapping, and investigate characterization for the continuity.

In this paper, we introduce the concept of fuzzy r-generalized almost continuous mapping and obtain some characterizations of such a mapping. In particular, we investigate characterizations for the fuzzy r-generalized almost continuity by using the concept of fuzzy r-generalized regular open sets.

Recent advances in augmented reality (AR) and virtual reality (VR) technologies have led to a significant increase in metaverse platforms. Metaverses are setting a new direction for the digital world. This paper examines the phenomenon of virtual worlds that are becoming an issue these days, focusing on [Ready Player One]. One of the common features of the metaverse platform in [Ready Player One] and the platforms currently in use is the concept of open world. This is a feature that goes beyond simply moving around in a virtual world and allows users to freely reset, participate in, and control the environment. This innovative concept is a hallmark of metaverse platforms, and it is becoming increasingly important and influential. Through this study, we focused on the [open world system] of the platform in the movie and the modern metaverse platform, and suggested and studied how the scalability of the metaverse will present a turning point in the future.

Open education started spontaneously in elementary school and accommodates positively as a result of educational reformation. Open education also contributes to the development of human nature. This developes a creative power and inhances independence according to a main task of school support for the 21st century. A premise of this study is how to fulfill a fresh and wide space field of learning which is an indispensable condition of open education. The study analysed the teachers' reactions to open education after classifying an atmosphere of reception, understanding concepts, and application. This examined the concept, basic principles, characteristics, teaching-learning activiters open education, and quality of learning. The method of research used was on the results from the percentages of questionnaires that were posted to the sample schools. Although the final outcome to open education can not be summarized, three preconclusions of open education are as follows; First an atmosphere of reception is spreading continuously day by day. Secondly, understanding the concept of open education is very important. Thirdly, go percent of all schools have experienced open education were applied to open education. Contrary to some affirmative reactions, there are some disadvantages to open education. incdule, poor educational environments, difficulty in managing schools, lack of repetition of old out-dated teaching skills. Finally in conclusion, we must learn to adapt to the new method of open education as our educational system for the 21st century can not simply rely upon the open education motto. Above all, we must support educational reform and enforce the development of education within the education act.

The purpose of this study is to find out how the aesthetic values and characters of the Avant-garde fashion through semantics analysis of Avant-garde experiments in the early 20th century. Inner expressions of Avant-garde fashion in future dynamism, alien-hostile, and surreal-experimentalism are as followings (1) Reject tradition of existing fashion concept, (2) Dismantle costume material and inter-text characteristics in fashion field, (3) Laugh at material civilization and elite fashion, (4) Pursue primitive and fundamental sensibility on non-civilized world (5) Express human estrangement due to material civilization, (6) Remove the barrier of fashion between luxury and cheap ones, (7) Time, space and purpose is mixed, (8) Open concept as space structure independent of human body, (9) Complicatedness, ambiguity and expression of irregularity as changeableness, (10) Dismantle concept of beauty and ugliness. As you see, fashion design in modern Avan-garde is pursuing newness as beauty of open concept, rejecting all modern tradition and allowing extremity such as experimental, illogic, unreasonable and non-formatted expressions.
