  • Rhizopus soft rot caused by Rhizopus stolonifer occurred on strawberry (Fragaria ${\times}$ ananassa) in the plastic boxes in Jinju City Wholesale Market of Agricultural Products at Gyeongnam province in Korea on April 2008. The infected fruits were rapidly softened, water soaked and finally rotted. The symptoms were mainly occurred through wounds at harvest time. The colony color was white, cottony to brownish black after fully matured and numerous sporangiospores were formed on sporangia. The optimum growth temperature of the fungus was $30^{\circ}C$ on potato dextrose agar. Sporangia were globose or hemispheric shape of white color at initial stage and gradually changed with black color of $82{\sim}195{\mu}m$ in size. Sporangiophores were $12{\sim}25{\mu}m$ in width. Columella were hemispheric in shape, and $70{\sim}92{\mu}m$ in size. Sporangiospores were irregular round or oval in shape, brownish-black in color and $9{\sim}21\;{\times}\;7{\sim}8{\mu}m$ in size. This fungus formed stolones and rhizoid on PDA. On the basis of symptom, mycological characteristics and pathogenicity of the fungus, the causal fungus was identified as Rhizopus stolonifer (Ehrenb.) Vuill.

  • This study examined the physical attributes and heat treatment characteristics of glass beads excavated from the Gimhae area, which is the location of Geumgwan Gaya. This enabled classification of surface characteristics of the beads based on the investigation of the color, size, and shape. The glass beads were classified into eight color systems, with purplish-blue beads as the representative color. Bead size was categorized into three types depending on the outer diameter and how it increased over time. Bead shapes were categorized as round, tubular, or doughnut-shaped based on the inner diameter and length, with round being the typical shape. According to the degree of heat treatment, there are three types of cross-section for glass beads that are manufactured by the drawing technique, most of which are the HT-III type. In addition, it is estimated that the heat treatment technology has more considerable effects than other methods. Through non-destructive analysis, the chemical composition was obtained and categorized as flux, stabilizer, and colorant. Analysis confirmed the presence of 63 and 9 pieces in the potash and soda glass groups, respectively. Overall findings from the study highlighted a correlation between the chemical composition and the external factors such as color, size, shape, and manufacturing technology of glass beads recovered from Geumgwan Gaya, revealing characteristics related to that time and region.

  • Most general content_based image retrieval techniques use color and texture as retrieval indices. In color techniques, color histogram and color pair based color retrieval techniques suffer from a lack of spatial information and text. And This paper describes the design and implementation of content_based image retrieval system using color space and keywords. The preprocessor for image retrieval has used the coordinate system of the existing HSI(Hue, Saturation, Intensity) and preformed to split One image into chromatic region and achromatic region respectively, It is necessary to normalize the size of image for 200*N or N*200 and to convert true colors into 256 color. Two color histograms for background and object are used in order to decide on color selection in the color space. Spatial information is obtained using a maximum entropy discretization. It is possible to choose the class, color, shape, location and size of image by using keyword. An input color is limited by 15 kinds keyword of chromatic and achromatic colors of the Korea Industrial Standards. Image retrieval method is used as the key of retrieval properties in the similarity. The weight values of color space ${\alpha}(%)and\;keyword\;{\beta}(%)$ can be chosen by the user in inputting the query words, controlling the values according to the properties of image_contents. The result of retrieval in the test using extracted feature such as color space and keyword to the query image are lower that those of weight value. In the case of weight value, the average of te measuring parameters shows approximate Precision(0.858), Recall(0.936), RT(1), MT(0). The above results have proved higher retrieval effects than the content_based image retrieval by using color space of keywords.

  • Voxel Coloring is one of the well known methods to reconstruct three dimensional shape from calibrated two dimensional multiple-view images. This paper proposes an advanced Voxel Coloring to complement drawbacks of previous color consistency tests. We propose an adaptive threshold using double threshold and an weight component to test color consistency. From the reconstruction experiment, we have verified that our proposed method outperforms the previous one.

  • The purpose of this study was to investigate the differences in the dissatisfaction with and design preferences for mountain gear among the segments divided by specialization activity-pursued for recreational mountaineering. Data were collected by questionnaire survey from 900 subjects with the experiences of mountaineering and purchasing mountain gear in the past year, and 891 were used for the data analysis. The results of the study were as follows: Three factors were formulated based on mountaineering specialization activity-pursued: expertise-pursued mountaineering, mountaineering with psychological attachment and activity-oriented mountaineering. Four segments were identified based on the specialization activity-pursued: the emotionally-committed, the continuously-participated, the expertise-pursued, and the passively-participated. Significant differences were found in dissatisfaction with and design preference for mountain gear among the segments. The expertise-pursued tended to be more dissatisfied with color and fabric than the others, and preferred various mountain gear design of shape, color combination and construction line. On the other hand, the passively-participated tended to prefer simple and comfortable style with solid color and simple color combination.

  • The purpose of this study was to closely examine the history of glasses and their cases used in the middle and late of Joseon Dynasty and identify inherent quality of our traditional glasses cases through color analyses of glasses cases' material and shape. While theoretical examination was conducted based on the literatures of glasses and their cases that firstly appeared in around Japanese Invasion (Imjin war) of Korea in 1592, practical analyses were demonstrated on photos of glasses cases used in the middle and late of Joseon Dynasty collected from both museum pieces and the internet which were grouped into wood, fabric, paper, sharkskin, hawksbill and cow's horn in accordance with their materials. 623 color samples were abstracted from collected 159 glasses cases and quantity analyses on each material were performed respectively. Abstracted representative colors based on the result of color analyses were classified into the main materials and accessories' color scheme. The result of this study are as follow: firstly, both Yellow and Yellow Red were mostly used in main materials. In Fabric case's colors were widely used in embroidery and in animal matter material cases such as sharkskin, hawksbill and cow's horn, which can be used as itself or dyed, Green Yellow shown in high frequency. Secondly, accessories were analyzed into similarity coloration with main materials. From this finding, it turns out that our traditional cases have characteristic of similarity coloration between main materials and accessories. Red Purple and Purple Blue in high frequency in accessories used as an accent color. Finally, based on the analysis of hue and tone, while the middle and low value colors shown in very high frequency, the high-chroma colors hardly shown.

  • The purpose of this study is to find the character of Cleopatra (69 B.C-30 B.C) by analyzing materials about Cleopatra, and to figure out symbolism and costume presented in movie . Costume of the main character, Cleopatra, compound the type of Egyptian traditional clothes, the change of it, and the trend in the 1960's. And, the symbolic meaning of it is also reinforced by adding ancient Egyptian myth to it. This kind of symbol is usually represented in Cleopatra clothing, especially in weaving pattern, embroidery, and ornament. And color of the clothes not only have their on predominance, but also can have their meaning fade away by mixed with each other, and also the shape has relation with the meaning of color. To sum up, the color and pattern of ancint Egyptian Cleopatra as alive formalize the power that come from coherence with the sun god in the center, which a used to maintain the power of the king. Costume in movie also contained color and pattern as a symbol of religion to symbolize the absolute power of king. These kinds of symbols are reemerging through historical recurrences and exotic interests.

  • Underwater photographing and image recording are essential for pre-excavation survey and during excavation in underwater archaeology. Unlike photographing on land, all underwater images suffer various quality degradations such as shape distortions, color shift, blur, low contrast, high noise levels and so on. Outcome is very often heavily photographing equipment and photographer dependent. Excavation schedule, weather conditions, and water conditions can put burdens on divers. Usable images are very limited compared to the efforts. In underwater archaeological study in very turbid water such as in the Yellow Sea (between mainland China and the Korean peninsula), underwater photographing is very challenging. In this study, off-site image distortion and color compensation techniques using an image processing/analysis software is investigated as an alternative image quality enhancement method. As sample images, photographs taken during the excavation of 800-year-old Taean Mado Shipwrecks in the Yellow Sea in 2008-2010 were mainly used. Significant enhancement in distortion and color compensation of archived images were obtained by simple post image processing using image processing/analysis software (PicMan) customized for given view ports, lenses and cameras with and without optical axis offsets. Post image processing is found to be very effective in distortion and color compensation of both recent and archived images from various photographing equipment models and configurations. Merits and demerit of in-situ, distortion and color compensated photographing with sophisticated equipment and conventional photographing equipment, which requires post image processing, are compared.

  • This study aimed to provide the basic data of the establishment of marketing strategies by dividing consumer groups in accordance with the pursuit of clothing benefit, and then understanding the importance of clothing selection criteria in those groups, whether there are any differences in it between groups, and whether there are any differences in preference of clothing color depending on the mood state of those groups. The scale of this study was comprised of the pursuit of clothing benefit factors, clothing selection criteria factors, and the factors related to preference of clothing color by each mood state. In the results of the analysis, the factor most considered when male and female consumers in 20s~30s purchase clothing was fitting, and followed by convenience, stable shape, condition, design, and others' reaction in order. However, those 'design', 'convenience', 'others' reaction' and 'condition' factors were significantly different between groups. Therefore, the significance of this study is that fashion brands could develop new positioning maps for marketing and promotional strategies based on the pursuit of clothing benefit shown in this study.
