This study classified outer-ring galaxies using 25,308 galaxies within z=0.05 from the SDSS DR7, which are larger than R_pet>6 arcsec and whose minor-to-major axis ratio (b/a)<0.6. We selected 531 galaxies that have ring-like structures by visual inspection of the color images of 25,308 galaxies; these galaxies with ring-like structures served as a primary sample from which we selected 90 outer-ring galaxies. The final sample of 69 outer-ring galaxies was selected by examining the photometric properties of the candidate galaxies. Their properties were determined by conducting surface photometry on their u, g, r, i, and z images. The frequency of the outer-ring galaxies was found to be 0.3% of the local galaxies. We examined the environment of the outer-ring galaxies using two measures of environment, namely, the projected distance to the nearest-neighbor galaxy and the local background density. We did not observe any notable difference between outer-ring and other galactic environments.

Eccrine poroma is a common benign cutaneous tumor that originates in an intraepidermal eccrine duct. This tumor exhibits acral distribution (sole, palm), and is rarely encountered in the head and neck area. In fact eccrine poroma in the postauricular area has only been rarely reported. A 55-year-old female visited our hospital with a main complaint of a mass that first developed in the left postauricular area about a year previously. The mass was painless, soft, protruding, domed, and dark red in color, and had slowly enlarged (at presentation it measured $1\times1cm$). Excisional biopsy was performed. Histological examination showed distinct features, and eccrine poroma was diagnosed. Follow-up at 6 months postoperatively showed no recurrence. The frequency of eccrine poroma is dependent on eccrine sweat glands density, and thus, usually occurs on the palms or soles. For eccrine poroma in the head and neck region, the differential diagnosis must rule out other masses, such as nevus, skin tag, pyogenic granuloma, cyst, basal cell carcinoma, and seborrheic keratosis. Importantly, 18% of poromas show malignant transformation, and can develop into porocarcinoma. For these reasons, an eccrine poroma in the facial area requires histological examination, complete excision, and follow-up.

This study investigated the effect of the money resource on the resource use behaviors of undergraduate students. The aim of the study was the examination of the relationship between undergraduate income and clothes-purchasing behavior. A total of 415 undergraduates residing in Gwangju City and Chonnam Province were interviewed by means of a questionnaire. SPSS 12.0 software was used for statistical analysis. Cronbach's $\alpha$, t-test, one-way ANOVA, Duncan's multiple range analysis and chi-square analysis were all conducted to acquire the results. The main results of this study are as follows. First, the average undergraduate income average was relatively high. Second, the motive for clothing purchases by undergraduates was to buy clothes similar to those which they already had. The undergraduates acquired their purchasing information from past experiences of buying clothes and considered design, quality and color when choosing their clothing. They purchased their clothes at retail stores and on average bought clothes about once a month. Although theaverage monthly expenditure on clothes was over 100,000 won, in general, the undergraduates spent between 50,000 and 100,000 won a month. They mainly paid cash when they purchased their clothes. Third, by analyzing the income, clothes-purchasing behavior, and clothes purchasing frequency of undergraduates, significant statistical differences in average monthly clothes expenditure and payment methods were detected. The results of the study can be used to understand the patterns of undergraduate money resource usage behaviors and can be utilized as an educational resource at home and within educational institutions.

The purpose of this study is to figure out the urban low-income consumers' present possesion condition of electric appliances, the way of purchasing, shopping scope of groceries and electric appliances, and the shopping scope and information seeking behavior of groceries and electric appliances according to the socioeconomic variables, and the shopping scope of electric appliances according to the way of paying price. For this purpose 129 low-income consumers living in Inchon were interviewed through questionnares. Finally 100 questionnares were analyzed. The first major of this study is that the possesion rates of color television set and refrigerator are comparativelyl high, while those of washing machine, record player and camera are low. In case of electric appliances, consumers usually purchase things on credit and as a shopping place, they usually go to a commercial agent. In case of groceries, they usually buy things for cash, and in case of one price labeled groceries they usually buy things at a supermarket. Second, according to the way of paying price, the shopping scope of some electric appliances is broader in case of purchase for cach than in case of purchase on credit. Third, the shopping scope and information seeking behavior classified by the socioeconomic variables according to the income, age and education. That is as the income and education become higher and the age becomes lower, the shopping scope becomes broader, mass media information source is much more uaed and the frequency of seeking becomes higher. Through this study, I would like to suggest the followings. (1) The problem of low-income consumers is closely connected with the low education level, so it can be solved a bit through consumer education. (2) Especially the consumers' problem is more serious in case of those who are aged and get very low income and education. Therefore special attention is needed to those consumers.

Harmful Algal Blooms (HABs), caused by Cochlodinium polykrikoides that causative fishery mortality, impact on aquaculture and economic loss appear particularly in summer and fall seasons in the Korean seas. It was studied on characteristics of HABs in the South Sea of Korea by using satellite and in-situ data. The in-situ data encompassed oceanic and meteorological data from July to October 2002-2008 and satellite data from July to October 2002-2006. Chlorophyll concentrations were calculated using Seaviewing Wide Field-of-view Sensor images by an Ocean Color (OC4) algorithm, and HABs were estimated using the Red tide index Chlorophyll Algorithm (RCA). The HAB occurrences were dominant when water temperature was $22.6-28^{\circ}C$ in August. The frequency of the individual numbers during 2002-2008, the HABs more than 1000 cells/ml (alert condition), were 73.57 %. In meteorological data from July to September during 2002-2008, the average precipitation, the mean air temperature, the mean wind speed and direction, and the sunshine were 9.31 mm/day, $24.07^{\circ}C$, 2.34 m/s and easterly, and 1-11 h, respectively. Our results suggest that the upwelling is caused by southwesterly wind in summer season and the Tsushima Warm Current which have influenced on the dispersion and moving of HAB (chlorophyll). In addition, the fresh water from Nakdong River, as the source of nutrients, also influences the occurrence of HABs.

This paper present the multi-modal user distance estimation system using mono camera and mono microphone basically equipped with a mobile device. In case of a distance estimation method using an image, we is estimated a distance of the user through the skin color region extraction step, a noise removal step, the face and eyes region detection step. On the other hand, in case of a distance estimation method using speech, we calculates the absolute difference between the value of the sample of speech input. The largest peak value of the calculated difference value is selected and samples before and after the peak are specified as the ROI(Region of Interest). The samples specified perform FFT(Fast Fourier Transform) and calculate the magnitude of the frequency domain. Magnitude obtained is compared with the distance model to calculate the likelihood. We is estimated user distance by adding with weights in the sorted value. The result of an experiment using the multi-modal method shows more improved measurement value than that of single modality.

With the popularization of the mobile phone with a built-in camera, there are a lot of effort to provide useful information to users by detecting and recognizing the text in the video which is captured by the camera in mobile phone, and there is a need to detect the text regions in such mobile phone video. In this paper, we propose a method to detect the text regions in the mobile phone video. We employ morphological operation as a preprocessing and obtain binarized image using modified k-means clustering. After that, candidate text regions are obtained by applying connected component analysis and general text characteristic analysis. In addition, we increase the precision of the text detection by examining the frequency of the candidate regions. Experimental results show that the proposed method detects the text regions in the mobile phone video with high precision and recall.

This study is designed to understand evaluation criteria for garment depending on demographic factors among college students in Yanbian, China. Questionnaire was used for measurement tools to study the subject of the thesis. The main study was conducted against 450 college students from May 17 to June 5, 2001. The data for the study were analyzed using SAS PC program for frequency distribution, percentage, t-test, and one way ANOVA. The evaluation criteria for garment are affected by demographic factors such as gender, average monthly household income, monthly expense for clothing. The result was showed as follows: The evaluation criteria for garment based on gender showed almost no meaningful different between male and female college students. Means on factors considered highly in selecting clothes was studied. The result shows that 'fit to the body, 'quality', 'color' and 'pattern' are considered most highly and 'harmony with other clothes', 'after service', design' 'easy to manage' and 'price' are considered relatively highly, but 'brand' and 'trendy fashion' were not considered highly. A meaningful difference was showed only in one area-trendy fashion-among three different income level groups. Those with an average monthly household income between 500 and 2,000yuan showed a highest tendency compared to those with above 2,000yuan and those with 500yuan. In terms of evaluation criteria for garment based on monthly expense for clothing, 'brand' is the only area which showed a meaningful difference. Respondents with monthly clothing expense of above 100yuan showed a higher means than those with below 100yuan.

In this paper, we present a novel segmentation method that can extract new foreground objects from a current frame in real-time. It is performed by detecting differences between the current frame and reference frame taken from a fixed camera. We minimize computing complexity for real-time video processing. First DCT (Discrete Cosine Transform) is utilized to generate rough binary segmentation maps where foreground and background regions are separated. DCT shows better result of texture analysis than previous methods where texture analysis is performed in spatial domain. It is because texture analysis in frequency domain is easier than that in special domain and intensity and texture in DCT are taken into account at the same time. We maximize run-time efficiency of DCT by considering color information to analyze object region prior to DCT process. Last we use Guided filter for natural matting of the generated binary segmentation map. In general, Guided filter can enhance quality of intermediate result by incorporating guidance information. However, it shows some limitations in homogeneous area. Therefore, we present an additional method which can overcome them.

21st century is the Age of Culture, and a period that is represented by symbolism and imagery. This is no exception for the countries that want to enhance their image in the international community. In order for a country to improve its brand, it has to select a representative emblem, symbols and cultural items. The usual suspects for this are its name, flag, and anthem. Each of these items can elicit different types of symbolism. It can also be used to differentiate the country from others; however, these are not the only sources of symbolism at the country's disposal. Other popular tools include cultural heritage, both tangible and intangible, climate, natural environment, and its national character. A country can use these items to associate itself with certain images. The purpose of this study is to find an objective way to effectively boost Korea's brand. This will be done by comparing and contrasting the ways countries including Korea have used their national emblems to enhance their image. Data from each of the countries were collected and analyzed. The results of this study will become empirical evidence in researches aimed to develop fashion designs that use Korea's national emblem as its motif in order to improve its national brand Countries that were used for this research were United States, United Kingdom, Japan, France and Korea, and they were chosen because their national brand rated highly. The items selected for the analysis were scarves and neckties. This was because, compared to other fashion items, it was easier to sort out scarves and neckties that used motifs of national emblems as well as these two items having the highest usage rate of this type of motif. Group of experts looked through a combined total of 370 scarves and ties and they analyzed the following factors in the design: type of motifs, frequency, use of color, methods of expression and images.
