  • In this paper an omni-directional mobile robot is suggested for educational robot platform. Comparing to other robots, a mobile robot can be easily designed and manufactured due to its simple geometric structure. Moreover, since it is required to have low DOF motion on planar space, fabrication of control system is also simple. In this research, omni-directional wheels were adopted to remove the non-holonomic characteristic of conventional wheels and facilitate control system design. Firstly, geometric structure of a Mecanum wheel which is a most frequently used omni-directional wheel was demonstrated. Then, the organization of the mobile platform was suggested in aspects of mechanism manufacturing and electronic hardware design. Finally, a methodology of control system development was introduced for educational purpose. Due to an intuitive motion generating ability, simple hardware composition, and convenient control algorithm applicability, the omni-directional mobile robot suggested in this research is expected to be a promising educational platform.

  • An accurate evaluation of educational process is a promise for the progress of education, because evaluation provides a meticulous idea of what has actually been achieved as a result of education. However, for all its significance in the educational fields, there are not many discussions about evaluation in South Korea. We believe that in order to overcome this discrepancy, diverse evaluation theories along with a discussion about the merits or demerits or each theory should be introduced in South Korea. We propose that Eisner's educational evaluation model may suggest alternative ways of perceiving evaluation. Eisner's educational evaluation model, named educational connoisseurship and criticism, emerged as an approach to educational evaluation from the methods used in art and literary criticism.

  • Under the regulation of rational energy use in public institutions, it has been mandatory for educational facilities to meet the first grade or higher since 2014. Also the regulation has forced educational facilities as public institutions to use renewable energy since September 2008. Educational facilities are required to be qualified as zero-energy buildings from 2020 under the revision of the Green Building Act. In this study, we identified the current status of the building energy efficiency rating system and the renewable energy system installation for 316 educational facilities that were accredited as "building energy efficiency rating system" from February 2015 to March 2019. Also we analyzed the energy self-sufficiency rate based on energy requirements and renewable energy output. Of the 316 facilities, 12 had 1++ and 293 had 1++ for the "Building Energy Efficiency Rating System". Among the 12 facilities which had 1+++, 11 recorded ZEB level 5 or higher, and 28 out of the 293 facilities(11%) which got received 1++ had ZEB level 5. Thus, it is impossible to implement the ZEB certification system for educational facilities under the present conditions. Expanding the ratio of 1+++ and investing in renewable energy systems should be preceded.

  • This study aims to examine the integration process of educational system and school structure of the former East Germany into the Federal Republic of Germany following German unification. More specifically, the study focuses on drawing some policy suggestions and implications for achieving integration of South and North Korean educational system in a unified Korea. In fact, the school structure in the former East Germany had been integrated into West German educational system and school structure before and after official German unification by way of so called transitional process. The results of the study indicate that the integration process of school structure in the former East Germany into West German educational system was quite successful with stable management by means of various transitional measures and reaching an agreement between East and West Germany. Additionally, the study presents that local characteristics regarding school structure in the former East Germany were recognized and introduced in the integration process and they managed to handle the social change situation after German unification flexibly. However, it shows some shortcomings because it had been carried out in too short a period of time and the positive factors of school structure in the former East Germany had not been enough taken account into the integration process, along with the lack of inner comprehensive relevant infrastructure. Furthermore, the study points out that German case of school structure and its integration process after German unification has implications for specific ways Korea should pursue to achieve integration of South and North Korean educational system in a unified Korea. To be more specific, it suggests how we come up with plans and measures to establish integration of South and North Korean school structure in a stable way especially in terms of dealing with North Korean school structure and building an inner infrastructure.
