There have been a lot of efforts to adapt climate change around the world, and Korea is no exception. The low carbon green cities for overseas have had many different forms through their own special models and strategies. Korea needs a model and strategy of Korean low carbon green city, which is suitable for Korea climate and topography. This study pays attention to the Pungsu, which is Korean traditional thinking system for space, and examines the way for selecting locations and space planning to create the Korean low carbon green city through the contemporary interpretation of the Pungsu. For this purpose, first of all, this study makes efforts for the contemporary interpretation of the past Pungsu theory from the modern city's perspective, through understanding the difference between the Korea's historic villages(cities) and the modern cities. Based on the contemporary interpretation of the Pungsu theory, this study finds ways of application the system on selecting locations and space planning in the Pungsu theory to create the Korean low carbon green city.

Fast developing digital technology is Having an enormous societal influence, creating a porous new world without boundaries. This phenomenon applies to a whole range of fields, including culture, politics and even our daily lives. Urban Street cannot be excluded from this world-transforming change. Digital technology is changing the physical structure, growing patterns, function and role of the Urban Street. As a result, Urban Street should now be freeing themselves from the old-world functionalism, which has been pursued uniformly under the names of rationality and efficiency. We have, then, to think about the culture of the Digital Urban Street,'that is, the digital life style, which is tangibly generated in the concrete city space, and which must be prepared for further digitalization. This paper argues that the street must be understood as a communications centre, because digital technology has created a new communications style. Also, this paper focuses on how the physical environment of Urban Street will evolve with regard to both function and appearance. In conclusion, studying the ubiquitous space, it also looks at how existing urban planning and space design should lead to the further development of Urban Street using digital technology, as well as to the role this technology will have in the future.

With the rise of the Fourth Industrial Revolution and I-Korea 4.0, both of which pursue strategies for industrial innovation and for the solution to social problems, the real estate industry needs to change in order to make effective use of available space in smart environments. The implementation of smart spaces is a promising solution for this. The smart space is defined as a good use of space, whether it be a home, office, or retail store, within a smart environment. To enhance the use of smart spaces, efficient decision-making and well-timed and accurate interaction are required. This paper proposes a smart space based on platform which takes advantage of emerging technologies for the efficient storage, processing, analysis, and utilization of big data. The platform is composed of six layers - collection, transfer, storage, service, application, and management - and offers three service frameworks: activity-based, market-based, and policy-based. Based on these smart space services, decision-makers, consumers, clients, and social network participants can make better decisions, respond more quickly, exhibit greater innovation, and develop stronger competitive advantages.

Activities in fields based on internet virtual reality are flourishing. Education field is not an exception, and has reached the stage of establishing a cyber university after showing its activity in the developing field of distance learning. Although some of the architectural education fields have been following this trend, the education field of architectural design has not been developed as wildly because there have been a lot of difficulties in expressing three-dimensional space on a two-dimensional web. However, it has become possible to actualize the remote lecture based on internet in the education field of architectural design through the latest developments in internet technology. The purpose of this research is to be a basis for developing a teaching method for architectural design by taking advantage of the advanced in virtual reality technology on the internet.

The radiation source used for non-destructive testing have permeability and cause a scattered radiation through collisions of surrounding materials, which causes changes in the surrounding spatial dose. Therefore, this study attempted to evaluate and analyze the distribution of spatial dose by source in the working environment during the non-destructive test using monte carlo simulation. In this study, Using FLUKA, a simulation code, simulates ⁶⁰Co, ¹⁹²Ir, and ⁷⁵Se source used in non-destructive testing, The reliability of the source term was secured by comparing the calculated dose rate with the data of the Health and Physics Association. After that, a non-destructive test in the radiation safety facility(RT-room) was designed to evaluate the spatial dose according to the distance from the source. As a result of the spatial dose evaluation, ⁷⁵Se source showed the lowest dose distribution in the frontal position and ⁶⁰Co source showed a dose rate of about 15 times higher than that of ⁷⁵Se and about 2 times higher than that of ¹⁹²Ir. In addition, the spatial dose according to the distance tends to decrease according to the distance inverse square law as the distance from the source increases. Exceptionally, ⁶⁰Co, ¹⁹²Ir, and ⁷⁵Se sources confirmed a slight increase within 2 m of position. Based on the results of this study, it is believed that it will be used as supplementary data for safety management of workers in radiation safety facilities during non-destructive testing using radioactive isotopes.

This paper identifies public transit-poors and derives spatial characteristics of the poors' distribution in an urban area by utilizing buffering analysis of geographic information systems and remote sensing techniques in the case of Daegu metropolitan city. Since special attention is given to elderlies, this study assigns three hundred meter buffer from bus/subway station as service boundary for elderlies. The results of this study tell us that 1) the transit-poors are concentrated on suburban and rural regions, 2) high proportions of the transit poors are elderlies with spatial variations in many regions, 3) the main housing type of the transit-poors is single detached house. We expect that this study can contribute to build an effective policy-making by showing essential technical processes and methods in identifying policy-need groups and their characteristics of spatial distribution.

Technological innovations in the 21th Century greatly change the society. The radical advance in computer science brought changes and increased efficiency into society in general. The field of archaeology is also highly influenced and attempts to improve previous manually conducted field survey and research have been actively made. In order to supplement incomplete data set from archaeological excavation, the ways to use computer have been highly explored. GIS is one of them. However, use of GIS has been limited to document locations and to produce distribution map of features using digital map. There are no proper guides to employ GIS for academic research, so that it is hard for beginners to learn how to make use of GIS. In this paper, functions of GIS are introduced even for beginners, including definition of GIS and its archaeological use. It is also explained how to get DEM from digital map to do spatial pattern analysis. Various GIS special pattern analyses using DEM and 3D simulation are presented, as well.

게임에서는 장애물이 가로 막고 있을 때 길 찾기 알고리즘이 요구된다. Path Finding Method 는 길과 장애물을 고려하여 목적지까지의 경로를 찾는 방법을 말한다. A^* 알고리즘은 이런 복잡한 미로 찾기에 최적화된 Path Finding 알고리즘이다. 하지만, 모바일 같은 저비용 기기에서 A^* 알고리즘을 사용하기엔 단순한 지형에서도 연산 부하가 발생할 수 있다. 본 논문에서는 가상의 공간에서 Grid를 구축하여, 통행이 가능한 곳과 불가능한 곳을 나누어 최종 지점에 도달할 수 있도록 하는 방식을 제안한다. 본 논문에서 제시한 Path Finding Method 는 최종 지점이 막다른 길인 경우 가장 가까운 이동 가능한 경로로 길을 안내하도록 설계하여 예외 상황에 대처했다. 대표적인 길 찾기 알고리즘인 Dijkstra 알고리즘은 최소 비용을 고려해서 최단으로 가는 거리를 비교하여 길을 나타낼 수 있다. 하지만, Dijkstra 알고리즘 경우 비용이 양수가 아닌 음수의 경우 무한 루프에 빠지는 등 결과 값이 제대로 나오지 않을 수 있다. 본 논문에서 제안한 Path Finding Method 는 최소 비용을 노드별로 비교하는 방식이 아닌 초기 비용을 알 수 없는 분야에 쉽게 사용할 수 있다. 본 논문에서는 제안한 Path Finding Method 를 적용하여 Web 게임을 제작하는 것에 성공하였다. 향후, Path Finding Method 결과에 위치 정렬 알고리즘을 적용하여, 중복된 지역을 가는 확률을 최소화하면서 정리된 Path 가 돌출되도록 연구할 예정이다. 본 논문의 Path Finding Method 은 게임 개발 분야에 적극 기여되길 바란다.

Regarding to Dandong as the gateway city of the Sino-North Korea trade, cultural anthropology characterizes it with a hybridity of four groups with a different combination of ethnic and national identity: Korean Chinese(Chosonjok), South Koreans, North Koreans and Chinese-North Koreans. And, microeconomics views the enterprises in Dandong area have different sizes and types in the Sino-North Korea cross-border trade depending on their owner's ethnic and national identity. However, these researches focuses mainly on the differences between the groups, falling short in showing how the group members utilize their double identities to maintain and prosper their businesses, coping with various and changing situations. This study introduces the concept of 'identity juggling' and applies it to Chosonjok cross-border traders. The results from the in-depth interview and survey indicate they juggles their Korean ethnic identity and Chinese national identity selectively in terms of their bilinguality of the Korean and Chinese, mobility crossing China, South Korea, and North Korea, and prospects on the trade revitalization thanks to potential mitigation of tensions in Korea peninsula.
