This paper presents a comparative study on similarity measurement method based on characters in the body of a book written in Korean. We deduce using ratio of characters in the body of a book for measuring similarity and compare results of book similarity using three different similarity measurement methods through the experiment. And we measure similarity using SMC(Simple Matching Coefficient), Jaccard coefficient and cosine similarity based on extracted characters in six books which are history category. The proposed method can measure book similarity more detail than existing research and result of measurement using cosine similarity is more accurate than other two methods because cosine similarity considers not only presence of characters also frequency of characters in the body of a book. If measuring book similarity based on characters in the body of books, we expect quick and detail performance at books which are categorized history, biography, etc.

In the current era of medical image processing, identification of blood disorder through visual observation is the most difficult job. The observation based disorder identification has been the approximation task. The haematological disorders of white blood cells (WBC) are really frequent in medical practices. From the recognition of blood disorders, it can contribute to the categorization of certain diseases related to blood. With automated leukemia identification, medical expert can keep off the complexity of the environment and focus along the important medical information that this image provides. We aim for development of automated identification of leukemia using microscopic blood smear image database. The computer based identification for leukemia detection has reduced the chances of error. The early identification of leukemia disease plays a significant role because monitoring and prevention is possible in concern patients. This proposed scheme uses the most significant steps of image processing such as pre-processing, segmentation and matching. The leukemia smear image database is segmented using Otsu image segmentation and Maximally Stable Extremely Regions (MSER) technique employed for image pattern matching. The performance of the system is tested using false acceptance rate (FAR) and false rejection Rate (FRR). The proposed system reported accuracy of 95.12% where FAR is 5.0% and FRR is 4.75%. The author recommended the Otsu image segmentation and MSER image matching is the robust and dynamic approach for leukemia identification.

A steganographic scheme, matrix coding based data hiding(MCDH), is constructed from covering function. MCDH may enhance embedding efficiency, and meanwhile decreases the number of modified bits. A we-known MCDH is based on Hamming code HC(n, n-k), i.e., using a covering function COV(1, n=2 k-1, k), referred to as Hamming code data hiding(HDH). Since then, HC(n, n-k)+1 DH(H1 DH) was introduced, and it had a better embedding efficiency, when compared with HDH. However, both HDH and H1 DH have demerit of small embedding rate. To overcome this problem, we adopt pixel overlapping approach, optimal pixel adjustment process(OPAP), and Least Significant Bit(LSB) substitution to construct the Hamming+k with m overlapped pixels DH(Hk DH). Experimental results reveal that the proposed scheme exhibits a good embedding rate compared with previous schemes. Also, the theoretical estimation of average mean square error for these Hamming-like DHS are given to demonstrate the advantage of our Hk DH.

Due to the fast development and wide application of Web technology, online purchases have become the main method to buy airfare tickets. Because information about pricing factors is unavailable, it is difficult for customers to buy airfare tickets at the lowest cost or even at a relatively lower cost. Although several approaches have been proposed to suggest the optimal timing for purchasing airfare tickets, these methods are based on predictions of tomorrow's price information. Clearly, local optimal decisions which rely solely on tomorrow's price prediction can be misleading or incorrect, resulting in missed opportunities to buy tickets at a lower cost in the future. In this paper, a novel Optimal airfare Ticket Purchase decision-support Service (OTPS) is proposed, which makes continuous recommendations on the best purchase time before the departure date. OTPS is based on the strategy of the Dynamic ratio of numbers of Potential days with Lower Price (DPLP), which takes the fluctuation tendency of airfare prices for a period into consideration. Specifically, parameter values of the model are set in a route-specific manner and updated periodically to enhance the generalization ability and reliability of OTPS. Extensive experiments are conducted on the real-world ticket price dataset of multiple routes. The experimental results prove that OTPS shows superiority over other state-of-the-art solutions.

In the autonomous control network environment, there are various ways to manage the nodes located under the controller management. We have proposed a node management method for managing nodes of ad-hoc networks that operate in a wireless network environment, by proceeding with research previously. In ad-hoc networks, communication between users is provided only through direct connections between nodes. That means are Ad-hoc network technology supports mobility directly through routing algorithms. Therefore, in an ad hoc network environment, when a node connected to the node loses its loss due to node movement, the routing protocol transmits the traffic to be transmitted to the other node. In the SDN environment, the controller monitors, detects, and manages the traffic generated by the lower nodes. In this paper, we propose a hop count management method that supports multipath algorithm for node management in SDN controller.

Temporal testing of real-time software is critical. Search-based software engineering（SBSE） has shown its potential to assist the temporal testing by generating the test data. However, the generation of test data through SBSE requires multiple executions of the application program. Consequently, a huge amount of time is required to explore the given search space. This paper advocates the use of a prediction model in an SBSE-based test data generation methodology. The proposed prediction model eliminates the need of software execution during the fitness evaluation and hence reduces the overall time required for the generation of test data. The viability of the proposed approach is demonstrated with two different benchmarks.
