This study analyzed the effects of fashion creators' innovativeness and attractiveness on consumer response and orientation toward a sustainable relationship in personal media. A survey was conducted with consumers aged in their 20s and 30s who had experience in sharing video content or writing comments and participating in fashion creators' real-time broadcasting of personal media. The results show that the innovativeness of fashion creators was classified into originality, opinion leadership, variety, and adventurous spirit, while attractiveness was classified into physical, social, and professional attractiveness. Consumer responses were classified into either emotional or cognitive responses, and sustainable relationship orientation was classified into communication, sharing, and relationship sustainability. The originality and variety of the fashion creators positively affected the emotional and cognitive responses of consumers. Adventurous spirit positively affected emotional response, whereas opinion leadership positively affected cognitive response. In addition, the social and professional attractiveness of fashion creators positively affected consumers' emotional and cognitive responses. Emotional and cognitive responses positively affected consumers' sustainable relationship orientation. The originality and opinion leadership of the fashion creators positively affected the three factors of sustainable relationship orientation, while variety positively affected communication and relationship sustainability. Fashion creators' social and professional attractiveness positively affected the three factors of sustainable relationship orientation, and physical attractiveness positively affected relationship sustainability. The results of this study are expected to provide useful data on the direction of fashion startups using personal media and marketing as well as distribution strategies in the fashion industry.

Effective alerts will drastically mitigate the disaster impacts. One way to enhance the effectiveness is to prepare multiple alert distribution channels. In this paper, we propose a new emergency alert distribution system that will solve the weaknesses of the current distribution systems, such as Cell Broadcasting System and T-DMB Automatic Emergency Alert Service. The weaknesses are: the limitation of message length, small portions of terminals that can receive and display the alert signal, and one-way communication service. To solve these problems, we propose an emergency alert distribution system over the Internet with RSS (Rich Site Summary) format. The system also has the capability of adaptive alert filtering according to the receiver characteristics. We analyzed the characteristics of RSS as an alerting format, and draw functional requirements satisfying use case scenarios. We designed the system only with major requirements and verified it on our test bed. Sending richer message contents through various receiving terminals, the system will achieve more effective emergency alert service.

Cell segmentation which extracts cell objects from background is one of basic works in bio-imaging which analyze cell images acquired from live cells in cell culture. In the case of clear images, they have a bi-modal histogram distribution and segmentation of them can easily be performed by global threshold algorithm such as Otsu algorithm. But In the case of degraded images, it is difficult to get exact segmentation results. In this paper, we developed a cell segmentation system that it classify input images by the type of their histogram distribution and then apply a proper segmentation algorithm. If it has a bi-modal distribution, a global threshold algorithm is applied for segmentation. Otherwise it has a uni-modal distribution, our algorithm is performed. By experimentation, our system gave exact segmentation results for uni-modal cell images as well as bi-modal cell images.

As the use of smart devices is being increased rapidly by the development of internet and IT technology, the contents production and utilization rate are showing higher increase, too. In addition, the type of contents also shows very diverse forms such as education, game, video, UCC, etc. In the meantime, the contents are reproduced in diverse forms by reprocessing the original contents, and they are being serviced through the contents service platform. Therefore, the platform to make the contents reprocessing easy and fast is needed. As the diverse contents distribution channels such as YouTube, SNS, App Service, etc, easier contents distribution platform is needed, and the development of the relevant area is expected. In addition, as the selective consumption of the contents having easy accessibility through diverse smart devices is distinguished, the demand for the platform and service that can identify the contents consumption propensity by individual is being increased. Therefore, in this study, to vitalize the online contents distribution, the contents reproduction and publishing platform, was designed and materialized, which can reproduce and distribute the contents based on the real-time contents editing technology in URL unit and the consumer propensity analysis technology using the data management-based broadcasting contents distribution metadata technology and the edited image contents streaming technology. In addition, in the results of comparing with other platforms through the experiment, the performance superiority of the suggested platform was verified. If the suggested platform is applied to the areas of education, broadcasting, press, etc, the multi-media contents can be reproduced and distributed easily, through which the vitalization of contents-related industry is expected.

Acoustic radiation from a submerged elastic shell with an internal fluid surrounded by the bubble layer is studied with the modal theory. An omni-directional point source located on the center of the internal fluid is used as acoustic noise source. The unknown coefficients of modal solutions are solved using the interface conditions between media. To preserve the stability of the modal solution over wide frequency ranges, the scaled technique of modal solution is used. The bubble layer is modeled with four kinds of bubble distribution; uni-modal distribution, uniform distribution, normal distribution, and power-law distribution, based on the effective medium theory of Commander and Prosperetti. For each bubble distribution, the insertion losses are mainly calculated for the frequency. In addition, the numerical simulations are performed depending in the bubble void fraction, the material property of elastic shell, and the gap between the bubble layer and the elastic shell.

Intravenous urography (IVU) for urolithiasis is a radiologic examination to diagnosis stone in the ureter path using iodine contrast media, which is radioopacity material. The method includes compression on the upper iliac crest. The compression band prevents outlet of the contrast media through the bladder and enables easier movement to upper urinary tract. This usage depends on the policy of a hospital. Therefore, this study aimed to review and compare the characteristic of progress of contrast media either in compression and non-compression. The retrospective image measurement on 60 cases of intravenous pyelography was conducted at a hospital with the identical type and amount of contrast media as well as criteria for testing. Image measurement was limited to 5 minutes clip, which is optimal for progress of contrast media depending on usage of the compression band. Also, anatomical regions were set as following: "RP" is from renal pyramid to renal pelvis, "PL" is from renal pelvis to lumbar three endplate, and "IU" and "IL" for upper and lower parts from both iliac crests. Analysis has been conducted through the statistical method based on Fisher's Exact Test to find if there are differences of distribution with the anatomical regions with compression or no compression. It has been confirmed that there is no statistical significant difference as the video measurement on 30 cases of compression and non-compression group respectively resulted in P value of 0.580 from left and 0.711 from right (both 0.960). Therefore, it has been concluded that application of a compression band on an intravenous pyelography for urolithiasis patient does not meaningfully affect the progress of contrast media.

The genus Cordyceps known as an insect parasite forms a sclerotium in insect bodies and then produces perithecia on the single or multiple stromata produced from sclerotium. Collected Cordyceps were identified into 5 species: Cordyceps militaris, C. nutans, Cordyceps sphecocephala, Isaria japonica, and Torrubiella sp. The fruit bodies of Cordyceps in petri-dish cover were fixed by tape and put the lid on water agar plates to isolate these collected Cordyceps. The germinated spores were transferred from water agar to Potato dextrose agar(PDA) after six hours. Mycelial growth of C. nutans and C. militaris was the most successful on Hamada media and was also good on Complete media and PDA. Mannose as a carbon source was good for two species and Glutamic acid as a nitrogen source was satisfactory to C. militaris and Asparagine gave a good result to C. nutans. C. militaris and C. nutans showed similar mycelial growth rate on the media that contained thiamine-HCI, biotine or nicotinic acid as a vitamine. When conidia of C. nutans were inoculated to insects, mortality was high in Artogeia napi L, Hemiptera, Plutella xylostella and 50% in Orthoptera, 12% in Acantholyda posticalise M, but not Agelastica coerulea B. in Aphididae, C. nutans was collected from only Hemiptera in nature, but killing effect on other insects was proved. Mycelial growth and fruit-body formation were good on the media that consist of rice powder 5g, wheat flour 5g, water 100ml, but formed fruit-body was not complete stromata but a mass of conidia according to results of observing microscope.

Storage materials for a minimized storage system should be able to store much energy in small quantities, and to solve such a problem, salt hydrates such as CALCIUM CHLORIDE, SODIUM SULFATE, SODIUM PHOSPHATE etc. were considered as most suitable storage media in which phase change phenomena take place at low temperature. Therefore those salt hydrates were used as storage media in this study, and piped-storage tanks were manufactured vertically for the experiment. The characteristics of thermal storage media were investigated and the results are summarized as follows: 1. From the experiment of radial temperature distribution of vertical piped-storage system, the latent heat phenomenon did not occur in all storage media during heating process because of generations of heat due to the reduction in the number of water molecules. However, among those storage media CALCIUM CHLORIDE had most remarkable latent heat phenomenon during cooling process. Therefore CALCIUM CHLORIDE was considered as most suitable storage media. 2. Heat quantity transferred to the storage media was the largest in case of CALCIUM CHOLORIDE under the same conditions during heating and cooling process.
