Objective : Multisensory integration (MSI) is the essential process to use diverse sensory information for cognitive task or execution of motor action. Especially, visual and somatosensory integration is critical for motor behavior and coordination. This study was designed to explain spatial and temporal characteristics of visual and somatosensory integration by neurophysiological research method that identifies the time course and brain location of the SI process. Methods : Electroencephalography (EEG) and event-related potential (ERP) is used in this study in order to observe neural activities when integrating visual and tactile input. We calculate the linear summation (SUM) of visual-related potentials (VEPs) and somatosensory-related potentials (SEPs), and compared the SUM with simultaneously presented visual-tactile ERPs(SIM) Results : There were significant differences between the SIM and SUM in later time epochs (about 200-300ms) at contralateral somatosensory areas (C4) and occipital cortices (O1&O2). The amplitude of the SIM was mathematically larger than the summed signals, implying that the integration made some extra neural activities. Conclusion : This study provides some empirical neural evidence of that multisensory integration is more powerful than just combing two unisensory inputs in the brain and ERP data reveals neural signature relating to multisensory integrative process. Since this study is preliminary pilot study, larger population and criteria are needed for level of the significance. Further study is recommended to consider issues including effect of internally-driven attention and laterality of interaction to make the evidence by this study solid.

The practical value of the third place using ubiquitous digital technology has been increasing rapidly, therefore it is inevitable to educate students of spatial design in the interdisciplinary education system based on the unified technology of digital in order to cultivate leading designers to adapt new era of spatial design. After a research for the unified form of spatial planning and case studies of foreign educations, this study addresses the issues to classify the interdisciplinary teaching form into three educational categories digital interactive education, digital unified education and digital creative education. Finally, the study proposes the basic form of the ideal and futuristic education of spatial design with the distinguished results after conducting the model curriculum by the above categories.

The purpose of this paper is to systemize the spatial studies of logistics industry by arranging the partially scattered current studies on spatial studies of logistics industry overall. Logistics industry now builds a complex spatial organization which has been developed to the stages of independent optimization by materials management and physical distribution providing specialized logistics services, logistics, and supply chain management including IT and management step by step. The complex spatial organization of logistics industry has been systematized with geographical space and virtual space, disintegration and integration, and intermediation and disintermediation. The three areas reported a dynamic characteristic overlapped in space. The dynamic characteristic has a dose relationship with interaction between IT and space of economic activities.

The spatial structure analysis using the existing space syntax has a weakness only to apply the road factor. Hence, it is necessary to perform a new spatial structure analysis considering the regional characteristics factor as well as the road factor. The purpose of this study is to propose a modified spatial structure analysis which adopts road and regional characteristics factors using the existing space syntax and GIS and then to apply it to the spatial structure analysis of the urbanized areas in Hapdeok town. For the new analysis, the experts' survey has been conducted to derive the spatial structure factors of the area and their relative weights. Specifically, it drew the road factor as well as the regional characteristics factors such as road, district, land value, and building density. This study shows that the existing spatial structure analysis considering only the road factor does not reflect the actual spatial structure but the modified spatial structure analysis considering the road factor and the regional characteristics factors more accurately analyzes the spatial structure of Hapdeok town. Hapdeok is not an area where road networks were developed along main development axis and its centrality was changed, but an area where road networks were developed by effectiveness and equity and its centrality was changed by downtown decline. The towns like Hapdeok is more suitable for applying the modified spatial structure analysis method considering the regional characteristics factors. Further research is required for selecting characteristics factors and appropriate parameters in the modified spatial structure analysis. Further case studies await in other cities for conducting its verification.

Cellular Automata(CA) have been investigated and utilized as a theoretical framework and/or methodology for analyzing and simulating the properties and behaviors of many complex systems in various physical science and engineering field. Due to the conceptual elegance and effectiveness of implementing spatio-temporal dynamic models and the compatibility with raster GISs, recently a variety of modeling works using both CA and GIS have been published in GIS fields Most of spatial dynamic models introduced in previous research, however, were very limited and furthermore integrated CA-GIS system for practical modeling purpose are not developed yet. This study aims to develop an integrated CA-GIS system in which a CA simulator is used as an analytical engine for GIS providing a multipurpose spatial dynamic modeling functionalities. This integrated CA-GIS system is anticipated radically enhancing the current lacking dynamic modeling functionalities of GIS and being utilized as an powerful and effective tool for practical spatial dynamic modeling research.

유비쿼터스 서비스 개념의 확장으로 서비스 제공 공간인 유비쿼터스 지능 공간(USS: Ubiquitous Smart Space)에 대한 관심이 높아지고 있다. 또한 이와 같은 USS 개발은 전 세계적으로 다양한 분야에서 이루어지고 있다. 이러한 USS를 개발하기 위한 방법론 중에서 먼저 시나리오를 제작 분석하고 이에 따라 요구분석과 설계를 하기도 하며 역으로 개발에 고려하고 있는 유비쿼터스 기술로 먼저 설계나 요구분석을 실시하고 이후에 시나리오를 통하여 실현 가능성을 보이기도 한다. 그러나 시나리오 제작과 요구분석이 상호 유사한 내용을 공유하고 있음에도 불구하고 별도로 제작하는 과정에서 불일치와 많은 노력이 소모된다. 따라서 본 연구의 목적은 시나리오 제작과 요구분석에 이르는 과정을 구조적으로 통합하는 방법론을 제시하여 USS개발 초기과정에서의 효율성을 증대하도록 하는 것이다.

In recent days, efforts have been made voraciously to create urban spaces where everyone can enjoy an equal life by integrating the socially underprivileged groups including women, children, the elderly, etc. In order to create a inclusive city that accepts everyone regardless of social hierarchy, it is necessary to plan the city by incorporating the marginalized. The purpose of this study is to establish the strategy of inclusive city in each region. To accomplish the goal, we analyze and compile each of the studies that were scattered and make an integrated evaluation index, and evaluate the inclusivity for each region by these indicators.

With broadcasting telecommunication, rapid change detection, and construction of spatial information, a long reconnaissance, resources detection in dangerous area and natural disasters, which are difficult for manned aerial vehicles to perform, international recognition in UAV merely being used for limited military purposes has been changed and its demand for both civil and military purpose have been increased. However, considering the current situation that availability of UAV varies and its working areas also broaden, the stability of UAV and the problems of privacy protection are more important in integrated operation of UAV. In particular, the application of UAV system is urgent for the area where rapid decision making due to expedite data construction such as disaster, calamity, and the acquisition of spatial information for small area are required. However, since technical stability for UAV system and institutional regulation in regard of spatial information are not examined, and UAV system has not been integrated with aerial photograph, the limitation of UAV system has been presented. Thus, this study is aimed at analyzing domestic and foreign research trend and institutional research trend in terms of integrated UAV operation, and proposing its implications and the availability of integrated UAV operation for future national spatial information data construction.
