The relationship between innovation policies and locational competitiveness has emerged as an important area in the analysis of economic development, reflecting both the centralisation and decentralisation of globalising economic activities. The underlying spatial and institutional components are subject to a pattern of cumulative causation in which strategic interventions of policy actors exercise a decisive role in shaping competitive advantages, while promoting interactions with local and foreign partners both from the private and public sectors. The Singaporean development experience illustrated these strategic interdependencies of innovation policies and locational competitiveness. Based on her role as a manufacturing and service hub, Singapore is viewed as an infrastructural nodal point which is interconnected to global production networks. Paralleling efforts in the domain of technological innovation, Singapore's policies for locational competitiveness aim at an adaptive harmonisation of the needs of international investors with local developmental objectives. This orientation characterises also current efforts in promoting Singapore as a knowledge agglomeration with a distinct science base, expanding R&D operations and an innovation-driven pattern of economic development. In conclusion, the locational rationale of Singapore's innovation policies provides lessons for dealing with the spatial and institutional implications of technological globalisation.

This paper describes a design experience of a low-cost 6 DOF spatial tracker system where relative low accuracy and relatively long ranges, wireless communication will be achieved by means of low cost accelerometers and gyros with contemporary microprocessor. However, there are two key problems; one is the bias drift problem and the other is that single or double integration of acceleration signal suffers not only from noise but also from nonlinear effects caused by gravity. To be specific, beginning and stopping of hand motions needs to be accurately detected to initiate and terminate integration process to get position and pose of the hand from accelerometer and gyro signals, since errors due to noise and/or hand-shaking motions accumulated by integration processes. Several experimental results are shown to validate our proposed algorithms.

As the average size of web sites gets larger, users tend to experience more severe problems while navigating through the sites. In order to alleviate the navigation-related problems, this paper proposes two new navigation systems based on the spatial metaphor to the navigation in the real world. Prototypes of the two system, Complete Route Navigation(CRN) and Complete Survey Navigation(CSN), were developed and applied to four versions of test bed web sites, which were then used in an experiment to test the effectiveness of the two navigation systems. Results from the experiment indicate that the two systems are indeed effective in aiding users to navigate in a large scale web site, and have more positive impacts when provided together. This paper ends with the limits of the study results and their implications to the development of large-scale web sites.

This study examined emergency exit location with the most representing school floor type with a mathematical model that applied optimized algorithm in the field of engineering. Recent school buildings became much more diverse in floor planning than the old days. Nevertheless, architect's approach to building prevention against fire related emergency planning still relies on an personal experience and knowledge. Therefore, since school buildings are much more likely to be exposed to any fire related events, emergency exit planning has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type(node) and the minimum physical distance between spatial types(arc), can propose the most optimized emergency exit locations. Consequently, this study compared an architect's fire exit planning with the scientific outcome of this study and suggested the most reliable emergency exit locations.

A well-maintained landscape can increase the competitiveness of a city. Gyeongju which is the famous ancient capital of Korea, has numerous historical resources. However, the disharmony between the historical landscape and the surrounding landscape weakens the competitiveness of the city. At present, most landscape analysis methods mainly focus on plans, photos, and animation, which have certain limitations in the expression of landscape spatial scale and materials. This study aimed to use the virtual walkthrough method to take the Wolseong District of Gyeongju historical areas as the object in order to evaluate the landscape visually. Compared with planar landscape analysis methods, such as photos and videos, the virtual walkthrough method is more immersive and intuitive to experience the spatial scale. The study results revealed images, visual characteristics, and visual influence factors of the landscape, which provide essential data for the construction and improvement of landscapes in similar historical areas in the future.

Traditionally, pathologists microscopically examine tissue sections to detect pathological lesions; the many slides that must be evaluated impose severe work burdens. Also, diagnostic accuracy varies by pathologist training and experience; better diagnostic tools are required. Given the rapid development of computer vision, automated deep learning is now used to classify microscopic images, including medical images. Here, we used a Inception-v3 deep learning model to detect mouse lung metastatic tumors via whole slide imaging (WSI); we cropped the images to 151 by 151 pixels. The images were divided into training (53.8%) and test (46.2%) sets (21,017 and 18,016 images, respectively). When images from lung tissue containing tumor tissues were evaluated, the model accuracy was 98.76%. When images from normal lung tissue were evaluated, the model accuracy ("no tumor") was 99.87%. Thus, the deep learning model distinguished metastatic lesions from normal lung tissue. Our approach will allow the rapid and accurate analysis of various tissues.

Space dominates all the art activities human do and plays a role of providing aesthetic emotion. Architecture, sculpture, painting, and furniture, etc. these two and three dimensional works are represented in space and interpreted the role of its form, structure and function. Each area is different, but space has been studied in philosophy, physics, geometry, and mathematical studies, etc. and has been consistently interpreted and represented relating to a variety of human creative activity. Furniture is also three dimensional art being dependent on space. In the United States in 2004, I made the living room bench by applying the spatial concept at Rochester Institute of Technology. Two years later, this design was adopted by wendell Castle Collection, an American furniture company, then prototype were made and tested three times during a year, and then since 2007 as indoor benches it has been manufactured in the United States. The study's purpose is to order the process of its development based on the experience of bench production applied the spatial concept, and by analyzing the properties of spatial concept, I am planning to propose a new concept on interaction with the space and furniture for next.

The purpose of this study is to analyze the characteristics of interior space in his design hotel through the analysis of Tony Chi 's work and to present the direction of the design direction of the interior space of the design hotel in the future based on the results. The results are summarized as follows. First, the characteristics of the interior space of Tony Chi are divided into visual balance, repetitive rhythm, symbolic emphasis, exaggerated scale, design harmony, and physical borderlessness. Second, the spatial composition through visual balance was consistently shown in all cases, mainly by arranging elements such as furniture and lighting symmetrically. Third, the spatial composition through repetitive rhythm did not show its characteristics at the beginning of the works, but gradually appeared as repetitive rhythm expression using bold pattern. Fourth, Toni Chi constantly expressed the space composition through symbolic emphasis during the planning of the design hotel. Fifth, the exaggerated scale was mainly used to express the architectural detail vertically according to the height of the ceiling to express a grand space and appear in many works. Sixth, Toni Chi consistently expressed the composition of space through the harmony of design of oriental and western cultures, classical and modern designs in all cases. Seventh. In order to provide curiosity induction and aesthetic experience, spatial composition through physical borderlessness was used.
