Unexpected massive disasters have occurred around the world, causing enormous socio-economic damage. The military has long been enacting laws, organizing organizations and establishing systems for crisis and disaster management, but it did not consider the situation when military essential functions were suspended due to unpredictable and massive disasters. With the September 11 terrorist attacks, the U.S. military has developed COOP strategy aimed at continuing military essential functions in all crisis, and is contributed to national continuity by ensuring uninterrupted national security functions. Korean military has established a crisis and disaster management system, but focuses on managing and controlling disasters and crisis situations. Korean military needs a system to guarantee military essential functions even in national crisis beyond its management capabilities. In this study, We compared and reviewed the U.S. administration and military COOP guidelines and directives, ISO22301 international standards., and developed planning guidelines suitable for the Korean military situation by responding to detailed items based on ISO22301. In particular, the U.S. military(DoD, Army, Navy, Air Force) COOP guidelines were drawn and incorporated into the guidelines(such as protection and succession of command authority, the fulfillment of essential functions and operational security, etc.). The planning guidelines are expected to be used as reference materials for the introduction of COOP systems in the military and the establishment of plans in the future.

Unlike traditional cognitive theory, situated cognition theory has been understood as a pedagogical theory that highly reflects the constructivist nature of learning. In order to practice situated learning in school, situations in the classroom are very important in which real teaching and learning occurs. Due to the fact that learning is the process of mental activities which is considerably dependent on conditions and context, it focuses more on the learning process and real-situation experiences rather than the result itself. In mathematics education, teaching students the ability to solve given problems in a conventional way is not enough anymore. The purpose of this research is to suggest the direction of mathematical education in the classroom by analyzing the implications of situated cognition theory and situated learning for 'doing mathematics' in classroom teaching. In this research, we introduce briefly about situated cognition theory and situated learning, compare the phenomenon of mathematics in the classroom to that in the mathematician's mind, and finally propose the applications of situated cognition theory in the mathematics education based on three perspectives of situated cognition theory the embodiment thesis, the embedding thesis, and the extension thesis.

The purpose of this study was to identify the problems faced by students in sub-microscopic representation of acid-base reactions. Herein, we selected 30 students of 12^th grade science classes, who had studied various acid-base models. In order to investigate the sub-microscopic representation ability of the students, we developed nine items related to various contexts, such as one type of solute and solvent, two types of solutes and solvent, cases with water as solvent or with nonaqueous solvents. For all items, we consistently observed lack of concept of chemical change. In context of aqueous and nonaqueous solutions, the frequency of lack of concept of chemical bonding was high if ammonia was the solute or solvent. Moreover, the frequency of lack of concept related to the degree of electrolytic dissociation was high. Therefore, chemistry teachers should understand that students' ability to sub-microscopic representation of acid-base reactions can be enhanced by analyzing the difficulties faced by the students in solving diverse acid-base problems.

This study investigated the models of four countries' elementary mathematics textbooks in Ratio and Rate and identified how multiplicative perspectives on proportional relationships and the structure of proportion situations are reflected in the textbooks. For this, textbooks of 5th and 6th grade textbooks in Korea Japan, Singapore and U.S. are compared and analyzed. As a result, we can find multiplicative perspectives on proportional relationships and the structure of proportion situations on pictorial models, ratio tables, double number lines and double tape diagrams. Also, the development of Japanese textbooks from multiple batches perspectives to variable parts perspectives and the examples of the use with two models together implied the connection and union of two multiplicative perspectives. Based on these results, careful verification and discussion for the next textbook is needed to develop students' proportional reasoning and teach some effective reasoning strategies. And this study will provide the implication for what kinds of and how visual models are presented in the next textbook.

The purpose of this study is to suggest the necessary measures for the school safety experience education space to provide the elementary school students with the ability to provide safety education through experiences routinely and repeatedly. For this purpose, we investigated the conditions of safety experience in Jeollabuk-do and the case of other cities as a factor for operating the school safety experience educational space. In order to clarify the appropriateness of this, a questionnaire was conducted for the teachers in the local area. As a result of the analysis, it was found that the use of two classrooms in the place and the scale in the operation of the school safety experiential education space should be sought in various places such as hall, multipurpose room, and gymnasium according to the school condition. Experiential areas should be operated by elementary school students customized, but specialized facilities or large scale should be used for professional safety experience facilities. For efficient operation, the base school wanted to be located in a place where accessibility of other school students was easy, and that a school with sufficient space would be selected.

School libraries are one of the essential parts for high quality education. The Seventh Educational Cumiculum emphasizes the development of creative and autonomous students who can solve problems in a self-directed way. The Ministry of Education and Human Resources Development come into forcing the installation of school digital library since 2001. Also, the Ministry of Education and Human Resources Development has presented the Master Plan of School's Activation in July 2002. In this situation, the research and discussion on effective model of school digital library are very important. Thus, This study aims to design a model of school digital library differentiated School's sizes depending on primary and secondary school's current status. This study is proposed 4 facility model of school digital library based differentiated school's sizes and designed A-type, B-Type model on individual model.

The purpose of this study is to analyze the structure, and contents of the US national school library standards presented in the document National School Library Standards for Learner, Librarian and School Libraries made by AASL, and to provide basic information to refer to the direction and contents of Korean school library standards. AASL's National School Library Standards provide Learner Standards, School Librarian Standards, School Library Standards and Standards Integrated Frameworks that incorporate three previous standards, and emphasize the growth of learners and school librarians' competency by focusing on the educational activities of learners and school librarians. With the physical environment of the school library being somewhat established, it is necessary to establish standards for the educational content and competency of learners and teachers. And it is necessary to pay more attention to the materials including the contents of education.
