In this study, we tried to analyze the fusion parameters required to produce a high-resolution multispectral image using an image fusion technique and to suggest global fusion parameters. We analyzed the linear regression coefficients that can simulate the panchromatic image, and the fusion coefficients required for producing the fusion image. When the fusion images were produced using the representative fusion parameters, it was confirmed that the difference in DN value between each fusion image was quantitatively smaller than when the optimal fusion parameters were used. Therefore, this study can minimize the regional characteristics reflected in the fused image.

This paper presents a piecewise image denoising with multi-scale block region detector based on quadtree structure for effective image restoration. Proposed piecewise image denoising method suggests multi-scale block region detector (MBRD) by dividing whole pixels of a noisy image into three parts, with regional characteristics: strong variation region, weak variation region, and flat region. These regions are classified according to total pixels variation between multi-scale blocks and are applied principal component analysis with local pixel grouping, bilateral filtering, and structure-preserving image decomposition operator called relative total variation. The performance of proposed method is evaluated by Experimental results. we can observe that region detection results generated by the detector seems to be well classified along the characteristics of regions. In addition, the piecewise image denoising provides the positive gain with regard to PSNR performance. In the visual evaluation, details and edges are preserved efficiently over the each region; therefore, the proposed method effectively reduces the noise and it proves that it improves the performance of denoising by the restoration process according to the region characteristics.

Local governments have been actively introducing the CIP(City Identity Program), which identity their regional features and publicize the governments, to increase municipal identity and encourage the participation of residents since the self-governing system was enforced. However, some local governments didn't perform the intended purposes. Therefore this paper is to compare regional characters, symbols, slogans of the east-coast cities in Kanwon-do and to evaluate them as a tourism cities' image tools.

Change detection is one of the common research topics in remote sensing. In general, global change detection methods using image difference method, etc, are used in low resolution images and local change detection methods using floating windows, etc, are used in high resolution images. But, these methods have disadvantages in practical use. If changed area images are automatically produced, these images will be used in public area such as regional planning, regional development managements. In this research, we developed new change detection method applicable KOMPSAT EOC images. This method automatically produces subset images in changed area.

What is culture-products? Culture-products contains identity of nation and region. French critic Guy Sorman says "It is natural that buying culture-products when you travel any countries" Culture-products which contains our own cultural factors will give positive image of country. The research and development of grafting grudge experience culture-products was advanced the characteristic of area-culture that necessary is prerequisite. We need to develop culture-products which mixed regional culture and characteristic. We would like to research about Baekje culture and culture-products and sales products in museum. Museum is one of the tourist's attractions and great place to express regional factors. The culture-products are specially limited in the products which reflects a Baekje culture with Muryeong's tomb in Gong-ju and Baekje incense burner in Bu-Yeo it advanced. We hope that this research could help to understand market of culture-products and development.

This paper presents an efficient object-based color image-retrieval algorithm that is suitable for the classification and retrieval of images from small to mid-scale datasets, such as images in PCs, tablets, phones, and cameras. The proposed method first finds salient regions by using regional feature vectors, and also finds several dominant colors in each region. Then, each salient region is partitioned into small sub-blocks, which are assigned 1 or 0 with respect to the number of pixels corresponding to a dominant color in the sub-block. This gives a binary map for the dominant color, and this process is repeated for the predefined number of dominant colors. Finally, we have several binary maps, each of which corresponds to a dominant color in a salient region. Hence, the binary maps represent the spatial distribution of the dominant colors in the salient region, and the union (OR operation) of the maps can describe the approximate shapes of salient objects. Also proposed in this paper is a matching method that uses these binary maps and which needs very few computations, because most operations are binary. Experiments on widely used color image databases show that the proposed method performs better than state-of-the-art and previous color-based methods.

In this study, the service image of the public library was investigated to the users of the public library, and basic data to improve the service image of the public library was also analyzed. In order to analyze public library service image, survey was conducted to 143 users of regional central library in Daejeon Metropolitan City. The results are as followed. First, reliability and publicity was the most highly rated and service satisfaction was the least highly rated. Second, when it was expressed with service quality image, there was no large difference. Third, reliability-providing useful information, publicity-fair treatment, and tangibles-convenient facility had positive images. On the other hand, access-good traffic condition, responsiveness-providing prompt new information, and tangibles-comfortable facility had negative images. Fourth, higher age group had lower mean value from teens to sixties.

To infer the true state of a regional product's attributes, consumers use the image they have of the product's region of origin; however, products may have multiple countries of origin in their design, branding, sourcing and manufacturing becuase more products are increasingly a result of multi-firm and multi-country efforts. We examined how the country-of-origin image (country image and product image) affect international consumers' perceived value (function value and symbolic value) and purchase intentions of made-in China goods by extending and deepening the flexible model. Second, to investigate the differences of COO effects according to different types of country-of-origin we divided the traditional country-of-origin into two components: country-of-manufacture (COM) and country-of-brand (COB). We then explore how the impact of China's country image on consumers' perceived value and purchase intentions varies when China is the COM or COB of the same product. Six hypotheses were proposed to test our anticipations. We recruited 800 Korean adult consumers who previously purchased made-in China products to participate in the online investigation. Data analyses were conducted with confirmatory factor analysis and structural equation modeling using SPSS and AMOS. The main results are discussed as follows. First, the effects of China's COO image on Korean consumers' perceived value and purchase intentions vary when China is the COM or COB of a product. Second, a positive effect of the function value and symbolic value on the purchase intentions was found. Literature and practical implications of findings are discussed and suggested in the conclusion.

Noise reduction is an important field in image processing and requires a statistical approach. However, it is difficult to assume a specific distribution of noise, and a spatial filter that reflects regional characteristics is a small sample and cannot be accessed in a parametric manner. The first order image differential and the second order image differential show a clear difference according to the noise level included in the image and can be more clearly understood using the canyon edge detector. The Fligner-Killeen test was performed and the bootstrap method was used to statistically check the noise level. The estimated noise level was set between 0 and 1 using the cumulative distribution function of the beta distribution. In this paper, we propose a nonparametric noise reduction algorithm that accounts for the noise level included in the image.

Purpose: The purpose of study was to identify the relationship between body image and self-esteem in patients with chronic renal failure. Method The subjects of study were 97 patients with chronic renal failure who were outpatients at K medical center. B hospital, H hospital in Busan. Data were collected from Nov 15th to Dec. 17th, 1999. The instruments used for study were the Body Cathexis Scale and Rogenberg's Self-esteem Scale. Collected data were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffe test, and Pearson's correlation coefficients. Result: 1 The mean score for body image was $137.46{\pm}22.21$, the mean mark $2.92{\pm}0.47$, and the mean score of self-esteem was $30.80{\pm}8.76$, the mean mark $3.08{\pm}0.87$. 2. There was a significant difference in the score for body image according to educational level (F=5.189, P=.002) and type of residence (F=6.095. P=.001). 3. There was a significant difference in the score for self-esteem according to age (F=3.615, P=.009), educational level (F= 4.772, P=.004), marital status (F=3.498 P=.019) and presence of children (F=2.511, P=.014). 4. Body image in patients with chronic renal failure patients showed significant correlation with self-esteem (r=.519, P=.000). Conclusion: From this study, a relationship between body image and self-esteem in patients with chronic renal failure was identified. Therefore, nursing interventions are needed to promote body image and self esteem in patients with chronic renal patients.
