The purpose of this study was to investigate that to see how their traditional characteristics were reflected and expressed in Hanoi vietnamese contemporary public restaurants. For this, We visited Hanoi twice to have onsite research in August 2012 and 2013. According to the results of surveying Vietnamese public restaurants, all of the 12 cases had humane characteristics reflecting Vietnam traditional culture, showing Vietnamese unique traditional characteristics including intangible elements such as natural environment, life culture elements such as food culture, and formative aesthetic elements using indigenous ornaments. Different from luxury restaurants that had trade names on the theme of historical stories related to people or places and expressed various concepts formatively using photographs of Vietnamese politics and history and ornamental elements such as tableware, however, the public restaurants were simple in theme or concept. It is probably because most of the surveyed cases were situated in the old quarter to the north of the Hoan Kiem Lake and in the area to the west of the lake and their target customers were local people, so they reflected the Vietnamese traditional residence style and common people's life rather than designing the restaurants intentionally with specific concepts. As to the spatial expression characteristics of the surveyed cases, casual restaurants in Hanoi expressed only basic structure using basic construction materials and techniques with outdoor spaces in the form of Vietnam traditional tube house, and therefore, the overall atmosphere was contemporary. In indoor spaces as well, the general level was low, using uncharacteristic common design and color and cheap finishing materials and furniture. 83% of all cases showed the pattern of VM-VM-VT, being mainly contemporary by partially adopting Vietnamese unique ornamental elements for their outdoor and indoor spaces and using traditional elements supplementarily.

Generally the commercial high-resolution images have their coordinates, but the locations are locally different according to the pose of sensors at the acquisition time and relief displacement of terrain. Therefore, a process of image co-registration has to be applied to use the multi-temporal images together. However, co-registration is interrupted especially when images include the cloud-covered regions because of the difficulties of extracting matching points and lots of false-matched points. This paper proposes an automatic co-registration method for the cloud-covered high-resolution images. A scale-invariant feature transform (SIFT), which is one of the representative feature-based matching method, is used, and only features of the target (cloud-covered) images within a circular buffer from each feature of reference image are used for the candidate of the matching process. Study sites composed of multi-temporal KOMPSAT-2 images including cloud-covered regions were employed to apply the proposed algorithm. The result showed that the proposed method presented a higher correct-match rate than original SIFT method and acceptable registration accuracies in all sites.

This paper deals with noise suppression of multi-channel data captured by microphone array using multi-channel Wiener filter. Multi-channel Wiener filter does not rely on information about the direction of the target speech and can be partitioned into an MVDR (Minimum Variance Distortionless Response) spatial filter and a single channel spectral filter. The acoustic transfer function between the single speech source and microphones can be estimated by subspace decomposition of multi-channel Wiener filter. The errors are incurred in the estimation of the acoustic transfer function due to the errors in the estimation of correlation matrices, which in turn results in speech distortion in the MVDR filter. To alleviate the speech distortion in the MVDR filter, diagonal loading is applied. In the experiments, database with seven microphones was used and MFCC distance was measured to demonstrate the effectiveness of the diagonal loading.

One of the biggest problems found from the results of the various GIS-related projects is this. In spite of the fact that there is a national standards on GIS data structures, in building and managing the information on a variety of facilities in an area, each of the concerned organizations has been building the information using their own standards on the selection and organizations of the target facilities, naming convention, and coding regulations of the selected facilities. This distinctively exposes the limits and problems of the national GIS data standards in adopting to the regional GIS projects, resulting in considerable problems in sharing the information already built. The national GIS data standards, therefore, should be expanded and revised. As an effort to solve the above-mentioned problems, this paper suggests an idea on the revision and expansion of the national GIS data standards in the field of road and related facilities. It is believed that same efforts should be made for the other areas of the national GIS data standards to increase the applicability to various GIS projects.

Aerial photogrammetry, which is one of the most frequent used technology in mapping and surveying, has been appreciated for its work flow and accuracy to generate 2D and 3D geospatial data. In aerial photograrnrnetry, more than two photographs are taken over the same target area in different position with overlap. Using these photographs and minimum number of ground control points, 3D stereo model is so formed that the ground surface in reality is reconstructed through analogue/analytical plotter or digital photogrammetry system. In case of digital photogrammetry system, 3D geospatial data could be automatically extracted in partial. Recently, in the advent of aerial digital camera such as ADS40 and DMC, digital photogrammetry system will be in the frist place for generating 3D geospatial data. In this paper, we experimentally generated 3D geospatial data using digital photograrnrnetry system in the aspect of work flow.

The spatial distribution characteristics of damaged trees by the pine wilt disease appear scattered spots spreading from single dead trees. That is the reason why it is difficult to early detect damage and to prevent from extensive damage. Thus, it is very important to forecast and analyze the damage occurrences, to establish strategies for prevention, and to supervise them. However, conventional survey which observes around roads or residential areas by naked eyes was impossible to investigate completely, missing target areas and dangerous areas. Therefore, aerial forecasting techniques on the damaged area were developed using GIS, GPS, and helicopters for an accurate observation of systematic and scientific approach in this study. Moreover, advantages of the techniques application were confirmed to survey 972 dead tree samples at 349 position-coordinates in 32 cities (about $28,810km^2$), 2005. This study is expected to apply widely to find dead trees and the causes, particularly by pine wilt disease.

This study mainly focuses on evaluating how the triangular training operator could improve classification accuracy in SAR(Synthetic Aperture Radar) and VIR FCC(Visible Infra-red, False Colour Composite). The techniques for the determination of the most informative SAR/VIR combinations in the triangular space diagram, as developed tv the author of the paper, are given and the results obtained are presented. The SAR alone, VIR alone and SAR/VIR FCC classification showed trends for gradual improvement of accuracy. Accuracy distribution pattern for individual classes could be explained closely related to SAR/VIR signature components in the process of the triangular synergistic training. Due to contribution of SAR signature in training samples, it was possible to isolate major terrain features such as cloud cover area and roughness target with acceptable spatial precision. It is anticipated that this research output could be used as a valuable reference for distribution trends of classification accuracy obtained by triangular channel space based training in synergistic application.
