In this paper, we present a solution to the problems caused by using only text - based information as an index element when a commercialized missing person indexing system indexes missing persons registered in the database. The existing system could not be used for the missing persons inquiry because it could not formalize the image of the missing person registered together when registering the missing person. To solve these problems, we propose a method to extract the similarity of images by using OpenCV image processing and TensorFlow deep - running image processing, and to process images of missing persons to process them into meaningful information. In order to verify the indexing method used in this paper, we constructed a Web server that operates to provide the information that is most likely to be needed to users first, using the image provided in the non - regular environment of the same subject as the search element.

Digital signage is becoming part of daily life across a wide range of visual advertisements segments market used in stations, hotels, retail stores, hotels, etc. The current digital signage system used in market is generally works on limited user interactivity with static contents. In this paper, a new approach is proposed using computer vision based dynamic audience adaptive cost-effective digital signage system. The proposed design uses the Camera attached Raspberry Pi Open source platform to employ the real-time audience interaction using computer vision algorithms to extract facial features of the audience. The real-time facial features are extracted using Haar Cascade algorithm which are used for audience gender specific rendering of dynamic digital signage content. The audience facial characterization using Haar Cascade is evaluated on the FERET database with 95% accuracy for gender classification. The proposed system, developed and evaluated with male and female audiences in real-life environments camera embedded raspberry pi with good level of accuracy.

As AI technology is recently introduced into various fields, it is being applied to the fashion field. This paper proposes a system for recommending cody clothes suitable for a user's selected clothes. The proposed system consists of user app, cody recommendation module, and server interworking of each module and managing database data. Cody recommendation system classifies clothing images into 80 categories composed of feature combinations, selects multiple representative reference images for each category, and selects 3 full body cordy images for each representative reference image. Cody images of the representative reference image were determined by analyzing the user's preference using Google survey app. The proposed algorithm classifies categories the clothing image selected by the user into a category, recognizes the most similar image among the classification category reference images, and transmits the linked cody images to the user's app. The proposed system uses the ResNet-50 model to categorize the input image and measures similarity using ORB and HOG features to select a reference image in the category. We test the proposed algorithm in the Android app, and the result shows that the recommended system runs well.

Smart-Phones are utilized in disaster management field because it can deliver disaster information to large population simultaneously and quickly, and provide accurate information through situation-based service using the LBS(Location Based Service). To study on the utilization of smart phone for disaster information collection and dissemination method, this study suggest a framework which connects smart phone by loading application for reporting disaster. The disaster monitoring and situation dissemination system framework using smart phone is composed of 4 parts. First, smart phone application enters image, video, voice and text information and location of the disaster. Second, the disaster report reception and situation dissemination server receives the information, save in the DB, and send through smart phone SMS. Third, store into disaster information database. Fourth, display the disaster report and management information on 2D GIS, support the decision making process in deciding whether to manage as disaster, and disaster management web service which disseminates situation.

As records of Women's policies and organizations from 1945, there are reports, pamphlet, educational materials, books, and photos. At this time, preservation status of which is so vulnerable. These problems are caused by absence of archivist, small preservation space, and financial weakness. For solving these problems, an alternative is establishing archives specified at collecting and management of materials. It's more important to making database through systemized materials, so that general people also beyond professional researcher, by web server, easily access to information of Korean Women's history.

Proteins from the loin tissues age ranged from 0 to 24 months of ten Korean cattle were extracted, separated and compared on two dimensional(2 D) gels to identify the proteins whose expression is highly correlated to marbling. We also compared the difference of loin proteins between castrated and non castrated bull cows on two dimensional gels. As the marbling in the loin of the cattle is optimized at 18 to 24 months, eight proteins expressed significantly higher level in 24 month than in 0 or 6 month were selected in terms of isoelectric points(pIs) and molecular weights. Using these values, we searched the Swiss Prot database via the ExPASy molecular biology server with TagIdent program. The proteins with the nearest molecular weights and isoelectric points were selected from the lists. These possible candidates were confirmed by N terminal microsequencing of the eight selected proteins. Three proteins, myoglobin, hemoglobin and ATPase, whose N termini were not blocked could be microsequenced and found to be exactly matched to the selected candidates. It is suggested that the proteins increasingly expressed in marbling periods can be involved in meat color, lipid transport and flavor improvement.

This study introduces a technology utilizing digital images as electronic money by inserting watermark into the images. Watermarking technology assign contents ID to images and inserts the contents ID into the images in an unnoticeable way. The server that manages the issue and the usage of mage electronic money (called ‘WaterCash’ hereafter) stores issued contents ID to database and manage them as electronic money. WaterCash guarantees anonymity and prevents the forgery and modification of WaterCash based on semi-fragile watermarking technique. In addition, WaterCash is transferable and the illegal use of WaterCash can be prevented based on the watermarking technology. The watermarking .technology used in this paper was designed to be robust to image compression but vulnerable to intentional or non-intentional Image processing.
