This study examines the characteristics of service economies and their impacts on the spatial transformation of Korea during the last IS years. This study reviews the different perspectives for the tertiarization Process. It focuses on the spatial variation in the growth and location of Producer service industries. Based on the analyses of industrial and occupational compositions, services. particularly producer services, have played a major role in creating new job opportunities since the late 1980s. The ratio of services to merchandise trade is approximately 1:4, but service trades have increased since the early 1990s. Producer service activities have grown very rapidly, and the information processing service has been over-concentrated in Seoul. Further headquarters of bank and insurance services are overwhelmingly concentrated into Seoul. The firms whose headquarters are located in Seoul have linkage Pattern on a nationwide scale. The pattern of employment growth in producer services shows a clear core-Periphery disparity. In the light of the observed pattern of regional differentiation in producer service employment, some wider implications of the distribution of producer service activities for regional economic Performance are considered.

The issue of spatial equity in public healthcare services is an important issue in rural areas with lower healthcare resources. This study investigates spatial accessibility to public healthcare services by public transport, focusing on bus travel in Yeoju-gun, Gyeonggi-do. We comprehensively analyzed the spatial patterns of accessibility using the measures based on spatial interaction, and compared them with the accessibility patterns by car travel. As a result of analysis, the spatial disparity between the central part of Yeoju-gun (lower accessibility) and its peripheries (higher accessibility) was identified. More specifically, the area and population of lower accessibility areas are greater than those of higher accessibility areas, and the difference in the accessibility values between higher and lower accessible areas is considerably large. Moreover, the accessibility patterns appears somewhat different according to two different travel modes. In particular, about 20% of the entire area presented the opposite patterns between two travel modes. Interestingly, less populated peripheral areas are more included in higher accessible areas by car.

스테레오 매칭은 Robot Vision 분야에서 가장 활발하게 연구가 진행되어온 주제이다. 과거 많은 연구들은 스테레오 매칭 알고리즘의 정확도를 높이거나 처리속도를 개선하는 것 중 어느 한 쪽에만 집중하고 있었으며, 두 가지를 동시에 고려한 연구는 상대적으로 연구가 미흡한 실정이다. 본 논문에서는 영상의 공간적 중복 성질을 이용하여 스테레오 매칭 알고리즘의 처리속도를 획기적으로 개선하는 방법을 제안하고, 처리 속도 감소에 따라 증가되는 disparity map 추정 오차를 보상하는 기술을 제안한다. 구체적으로 Dynamic Programming (DP) 기반 스테레오 매칭 알고리즘에 제안한 속도 개선 방법을 적용하고, 개선된 Adaptive Support Weight Filter를 사용하여 보다 효과적인 오차 보상을 실현 하였다. 체계적인 실험을 통해, 본 논문에서 제안 하는 스테레오 매칭 알고리즘은 처리속도와 정확도를 동시에 개선할 수 있음을 검증하였다.

Keeping a system in stable state is one of the important issues of control theory. The main goal of our basic research is stability of unmanned aerial vehicle (quadrotor). This type of system uses a variety of sensors to stabilize. In control theory and automatic control system to stabilize any system it is need to apply feedback control based on information from sensors. Our aim is to provide balance based on the 3D spatial information in real time. We used PID control method for stabilization of a seesaw balancing system and the article presents our experimental results. This paper presents the possibility of balancing of seesaw system based on feedback information from stereo vision system only.

The purpose of this study is to analyze the characteristics of exhibition circulation through the movement pattern. It looks into the factoers under the influence with the visitor's movement. The method of analysis of investigation by following after visitors. The viewing behavioral of exhibition based on the time, speed, proportion of appreciation is classfied into three types of the profound, the general, the passing viewers. The characteristics of the viewing form of these patterns largely depend on the space elements which are the structure form. And particularly the position of exit, the width of exhibition space and the connection of exhibition space stand out the disparity of the factor of the spatial structure These three patterns bring about a lot of encounter in the exhibition space according to the difference of these routes consequently. So appropriate to the each pattern can offer visitors to more effective environment of exhibition.

Accesses to lands, houses, the Internet and other utilities are regarded as basic human needs to escape poverty and are required to recognize the relationships between the digital divide and socio-economical inequality. The digital divide might not be a single technical disparity, but stems from a complicated mixture of economic and socio-technical symptoms of inequality. There is growing awareness of scrutinizing causal mechanisms between the digital divide and poverty since combating poverty could be a primary step to mitigate the digital divide. In this paper, the Hexad model is proposed to explicate poverty interpretation by using 6 parameters as a major tool for partly assisting in poverty monitoring system in connection with land information. A solution model of the Internet is suggested to break the digital divide. It expounds a conceptual framework and new idea for poverty management to notify spatio-temporal locations of poor actors and geography of the digital divide when efforts of poverty eradication hinge on understandings of geographic location of digital disadvantaged groups through parcel-based land information.

Stereoscopic viewing is an efficient technique for not only computer vision but also remote sensing applications. Generally, stereo pair obtained at the same time is necessary for 3D viewing, but it is possible to synthesize a stereomate suitable for stereo view with a single image and disparity-map. There have been researches concerning the generation of the synthetic stereomate from remote sensing imagery. However it is hard to find researches concerning the restoration of occlusion in stereomate. In this paper, we generated synthetic stereomates from remote sensing images, focused on the occlusion restoration. In order to figure out proper restoration methods depending on the spatial resolution of remote sensing imagery, we tested several methods including general interpolation and inpainting technique, then evaluated the results.

In this paper, we propose a multi-view video codec for 3DTV system. The proposed algorithm is not only to reduce the temporal and spatial redundancy but also to reduce the redundancy among each view. With these results, we can improve the coding efficiency for multi-view video sequences. In order to reduce the redundancy of each view more efficiently, we define the assembled image(AI) that is generated by the global disparity compensation of each view. In addition, the proposed algorithm is based on MPEG-2 structure so that we can easily implement 3DTV system without changing the conventional 2D digital TV system. Experimental results show that the proposed algorithm performs very well. It also performs better than MPEG-2 simulcast coding method. The newly proposed codec also supports the view scalability, accurate temporal synchronization among multiple views and random access capability in view dimension.

The aim of this paper is to examine the long-standing regional disparities and social division in the UK which are considered one of the crucial facts of Brexit. Since Brexit, also, the changed regional development policies are reviewed. Regarding policy perspective, we delve into the process of the UK government's strategic policy choices, such as privatisation of public enterprises and financial reform, amid the neoliberal globalisation in the late 1970s, drawing its implication to us having similar problems. Besides, the UK's self-sustaining regional development fund, policy, and changed governance are dissected with several ongoing debates. Finally, this study asserts the necessity of the social consensus of regional disparity policies and the establishment of the spatial environment particularly in regions left behind, giving the quality and equity of life.
