The advent of powerful hardware and advances in high speed networks enabled synchronous learning, with teachers and students being geographically distributed but connected via computer networks. Today's synchronous learning systems are mainly based on video conferencing technology which provides audio, video, and joint editing of documents only, but does not take into account the specific requirements of teaching, for instance, controlling the course of instruction, raising hands, or reference pointing. A shared whiteboard is often the core part of these systems. Therefore, in this paper, we look into implementation issues in whiteboards of distance learning systems. Particularly, system architectures and concurrency control mechanisms are considered.

The idea that the mobile phone could be used in the education field recently comes from it's strengths. They have mobility, on-the-spot-study, portablity, immediacy and they are easy to connect to educational information. The application which I developed in this study is using Google-Map API and is based on GPS. It can share the information about the area where user is located like text data and pictures of geography, culture, and historical remains. This application makes the best use of the mobile phone's strengths. It's more effective and we can expect that users could manage resources of learning and do self-directed study in spite of being outside of the classroom or after regular classtime.

This paper aims to provide a context-specific interpretation on the shifting process of in-house R&D spaces in a large Korean firm in the context of rapidly changing markets and technology. Drawing on the case study of LG Electronics Company, one of the Korea's flagship companies, I examine the causes and mechanisms leading to a shift in domestic R&D spaces and the nature of learning processes between R&D teams and between R&D and other organizational units, particularly manufacturing. It appears that the current reshaping processes of domestic R&D spaces in LGE focus more on the clustering of core R&D laboratories than the geographical integration of conception and execution. However, it should not simply be viewed that such a move would be reduced to the linear model of innovation and organizational learning. Instead, it involves the firm-specific mode of regulating organizational competences. As contextual variables to induce such a firm-specific mode of organizational change, I consider the spatial form of organization, the spatial sources of knowledge and learning, and the powers of relational learning that can be made between distanciated actors and teams.

Since the Shimane Prefecture government in Japan enacted "Takeshima Day" in March 2005, it has held commemorative ceremonies with Japanese politicians present each year on February 22. Japan has marked Dokdo as its territory in elementary and middle high school textbooks, and the number of such references has been increasing in recent years. Shimane Prefecture, which is the area nearest to Dokdo is strengthening Dokdo education in its geography classes at elementary and middle schools as part of regional studies. The study and education on Dokdo was begun by social studies teachers in the Oki Islands in Shimane Prefecture, but now extends throughout the prefecture. The auxiliary educational materials regarding Dokdo produced in Shimane Prefecture include teaching guidelines for teachers, worksheets for students, CDs containing statistics and picture files, and two kinds of DVD movie clips for each grade. In particular, schools teach the damage to the Japanese fishery industry caused by Korea's illegal occupation of Dokdo. This will likely form anti-Korean sentiments among Japanese students. It is hoped that Korean and Japanese scholars will work together to develop Dokdo auxiliary textbooks in order to improve the correct historical understanding of Dokdo.

This research aims to figure out the impact of different reflective thinking methods on pre-service geography teachers' teaching knowledge. Four pre-service teachers in the same level were selected through the first simulated instruction, Then, different reflective methods were given them to carry out the reflection. Afterwards, they carried out their second simulated instruction. The change of average score of pre-service teachers was analyzed through the peer reviews and Paired samples T-test. The results are as follows. First, when the first peer review score were compared with second peer review, average score of all pre-service teachers improved. But, pre-service teachers who got cooperative reflection with a specialist had the widest variation in the increase level of average score comparing to those without reflection or reflective journal writing. Second, reflective journal writing through self-reflection led to their reflective thinking, but it did not induce them to reflective practice. Finally, pre-service teacher who got cooperative reflection with experienced teachers got the significant improvement in PCK through the T-test. In particular, it had significant statistical value in instruction section and understanding of students section. It demonstrates that the contextual section could be improved by self-reflection or repetitive class practices, while instruction section and understanding of students section needed consulting by assistants.

Coastal cities need disaster planning that accounts for the complex causes of environmental disasters such as high tides or tsunamis generated by typhoons, and of river or lowland flooding caused by heavy rains, etc. The elements of the disaster map were initially defined using a Geographic Information System (GIS) to allow for efficient information management. Complex disaster information elements were thus established in this study to create a disaster map of coastal cities. The range of information required for coastal cities includes the type of disaster, evacuation methods, available sheltering facilities, and learning content. These informational elements are intended to build on spatial information based on data available from the Ministry of Public Safety and Security as well as local governments.

The purpose of this study is to suggest the contents for geography education about East Asian cultural diversity. I chose "Human Relationship and Living-Habit" culture among East Asian diverse cultures and fixed 4 themes: family cultures, traditional cultures, friendship cultures and relationship cultures with other people. For making the lesson contents for East Asian cultural diversity, I analysed Geography 2009 Revised Curriculum and presented specific contents differently depending on grades. Until now, static and homogeneous cultures in East Asia have been emphasized mostly at school but cultures that are dynamic and related to students$^{\circ}{\phi}$ life are proposed in this study. Through understanding the differences of the East Asian cultures, it will be possible to expand mutual understandings among the East Asian people. This study will be a good alternative and paving the way for enhancing cooperations in East Asia.

Estimating the implicit value of housing assets is a very important task for participants in the housing market. Until now, such estimations were usually carried out using multiple regression analysis based on the inherent characteristics of the estate. However, in this paper, we examine the estimation capabilities of the Artificial Neural Network(ANN) and its 'Deep Learning' faculty. To make use of the strength of the neural network model, which allows the recognition of patterns in data by modeling non-linear and complex relationships between variables, this study utilizes geographic coordinates (i.e. longitudinal/latitudinal points) as the locational factor of housing prices. Specifically, we built a dataset including structural and spatiotemporal factors based on the hedonic price model and compared the estimation performance of the models with and without geographic coordinate variables. The results show that high estimation performance can be achieved in ANN by explaining the spatial effect on housing prices through the geographic location.

The purpose of this study is to develop a role play instruction model to increase higher-order thinking abilities in geographical education. This study reviewed the references which included the contents of higher-order thinking abilities, and discussed the educational significance and application of role play instruction model. The developed role play instruction model was applied to four classes in high school in Korea. After applying the model, this study asked some question about the model to the students which engaged in this model. Higher-order thinking essentially means thinking that takes place in the higher-levels of the hierarchy of cognitive processing. Higher-order thinking abilities contain critical thinking abilities, creative thinking abilities, problem solving and decision making abilities, meta-cognition abilities. The role play instruction model is an effective method which can increase higher- order thinking abilities. The questioning to students which engaged in the class of applying to role play instruction model provides feedback about development instruction models to increase higher-order thinking abilities.

This paper aims to explore organisational change and learning involving spatial processes and outcomes. In particular, it focuses on the context specific nature of corporate learning and organisational change that can be found in the case of a large Korean firm facing radical economic change. Drawing on the case study of a large Korean firm, the Samsung Electronics Company, three main claims can be followed. First, territorial sources of learning influence the way in which the firm makes use of space/place. Second, corporate learning practices, however, are not based merely on specific localised sources or geographical proximity but on bringing together the local and the global sources by harnessing the properties of relational proximities. It reveals that firms are concerned less on specialising specific local knowledge than promoting organisational knowledge and competences by integrating a variety of knowledge distributed in and out of the boundaries of the firm. Finally, to learn and innovate in a continual basis, firms would attempt to combine codified knowledge with tacit knowledge.
