Unsupervised spectral angle classification (USAC) is the algorithm that can extract ground object information with the minimum 'Spectral Angle' operation on behalf of 'Spectral Euclidian Distance' in the clustering process. In this study, our algorithm uses the unit vector instead of the spectral distance to compute the mean of cluster in the unsupervised classification. The proposed algorithm (MUSAC) is applied to the Hyperion and ETM+ data and the results are compared with K-Meails and former USAC algorithm (FUSAC). USAC is capable of clearly classifying water and dark forest area and produces more accurate results than K-Means. Atmospheric correction for more accurate results was adapted on the Hyperion data (Hyperion-FLAASH) but the results did not have any effect on the accuracy. Thus we anticipate that the 'Spectral Angle' can be one of the most accurate classifiers of not only multispectral images but also hyperspectral images. Furthermore the cluster unit vector can be an efficient technique for determination of each cluster mean in the USAC.

This study mainly reports preliminary results from site investigation of the Great Pyramids and Sphinx in Egypt and sampling works where conducted in the same limestone beds in Mokattam quarry in Cairo. Analyses of composition of samples showed similar result to those of limestone in Giza and thus such samples can be easily used for further experimental work without disturbing real monuments. Future work will be concentrated on the change of engineering properties of samples before and after artificial weathering and the change of digital image acquired from the colored surface of monuments.

In automobile chassis system, several environmental factors weaken durability of automobile's components. The environmental factors are temperature, humidity, intensity of radiation and dust particle inflow. Especially, dust particle inflow leads to increase in friction and wear of automobile's components. The wear of automobile's component leads to increase in noise and exerts a bad influence on life of components. In this study, dust particles were investigated for study on the influence of dust particle inflow. Dust particles are collected on urban area, rural area and highway in China. The size of dust particle is analyzed using the image plus program, and the element of dust particle is analyzed using the SEM and EDX. The elements of dust particle are $SiO_2$ and $Al_{2}O_{3}$. The other elements(Na, Ca, Cl etc..) are detected on urban area and highway.

This paper examines the advertisements for mass-produced women's clothing, which appeared in the 1980s issues of the fashion magazine Wolganmeot. This study explores the communicative aspect of fashion advertisements of the 1980s as a platform for complex and dynamic interactions between fashion brands, female consumers, and the rapidly changing social, cultural, and economic conditions of the period. The research focuses on advertisements in the formal and character casual categories that targeted young, urban, and career-seeking women. Based on the analysis of the visual and textual elements of the advertisements from a pragmatics perspective, this paper concludes that fashion brands sought to highlight an 'intelligent', 'urban', and 'individualistic' image of women. It also proposes that the prevalence of assertive and straightforward textual elements, copies, indicates the efforts of fashion brands to stabilize and reinforce the advertising messages in the fast-evolving landscapes of the fashion industry and changing consumption habits.

Various matching methods have been introduced by investigators to improve digital elevation model (DEM) accuracy of satellite imagery. This study proposed an area-based matching method according to land cover property using correlation coefficient of pixel brightness value between the two images for DEM generation from IKONOS stereo imagery. For this, matching line (where "matching line" implies straight line that is approximated to complex nonlinear epipolar geometry) is established by exterior orientation parameters to minimize search area. The matching is carried out based on this line. Land cover classes are divided off into water, urban land, forest and agricultural land. Matching size is selected using a correlation-coefficient image in the four areas. The selected sizes are $81{\times}81$ pixels window, $21{\times}21$ pixels window, $119{\times}119$ pixels window and $51{\times}51$ pixels window in the water area, urban land, forest land and agricultural land, respectively. And hence, DEM is generated from IKONOS stereo imagery using the selected matching sizes and land cover map on the four types.

Vehicular traffic on turf results in loss of green cover due to direct tearing of shoots and indirect long-term soil compaction. Protection of turfgrass crowns from wear could increase the ability of turf to recover from heavy traffic. Plastic turfpavers have been installed in trafficked areas to reduce soil compaction and to protect turfgrass crowns from wear. The objectives of this study were to evaluate traffic performance of turfgrasses (Zoysia matrella and Axonopus compressus) and soil mixture (high, medium and low sand mix) combinations on turf-paver complex. The traffic performance of turf and recovery was evaluated based on percent green cover determined by digital image analysis and spectral reflectance responses by NDVI-meter. Bulk density cores indicated significant increase in soil compaction from medium and low sand mixtures compared to high sand mixture. Higher reduction of percent green cover was observed from A. compressus (30-40%) than Z. matrella (10-20%) across soil mixtures. Both turf species displayed higher wear tolerance when established on higher sand (>50% sand) than low sand mixture. Positive turf recovery was also supported by complementary spectral responses. Establishment of Zoysia matrella turf on turfpaver complex using high sand mixture will result in improved wear tolerance.

This study investigated the characteristics of outdoor advertising in downtown streets where the local governments improved and maintained. The purpose of this study was to examine how they met outdoor advertising guidelines in the basic landscape plan and how they contributed to the improvement of urban landscape. The outdoor advertising improvement project of local governments has contributed to the formation of downtown street landscape. However, as outdoor advertising is increasingly occupied in the landscape, it becomes a factor that hinders the landscape. Moreover, as outdoor advertising aims at advertisement, unique outdoor advertising has appeared, which is not matched with the surroundings. Therefore, it is necessary to take complementary measures. This study is a basic study to investigate the characteristics of outdoor advertising improvement which is a key element of urban landscape formation. Therefore, further study should be conducted on how an improved street image is evaluated.
