This study was aimed to develop ume flower image into a competitive fashion culture product image by reinterpreting the image in modern terms, manufacturing patterns and applying them to various items. In terms of method, ume flower petal was used as a motive and developed into a pattern, using Adobe Illustrator 10, a computer design program. Based on the symbolic image and realist form of ume flower, three new basic motives of new figurative image were set using form omission, simplification, overlapping, repetition and graphic elements. Each motive developed transformed patterns through the change, transformation, combination of colors. The repetitive unit of each motive set expressed geometrical patterns and combination of flower patterns using pattern repetition and $45^{\circ}$ repetition technique in combination with the check arrangement using quadrangle, and set the direction of design that would fit for each item of fashion culture products. Also, consistency and practicality were sought in the goods planning composition of each item by applying motive pattern results to the fashion culture goods, such as neckties, scarves, T-shirts that can be consumed in everyday life. It seems that more creative culture goods including ume flowers will be developed by seeing our own cultural elements as well as flower patterns like ume flower with modern trends.

In uplink cable modem link operated in time-division multiple access mode, it is crucial to employ a suitable preamble pattern enabling frame detection, coarse timing/carrier recovery. Preamble pattern based on the constant envelope zero autocorrelation sequence is proposed for the uplink cable modem compliant to the data over cable service interface specification. Frame detection, coarse/fine timing and carrier recovery algorithms suitable for the proposed preamble pattern are also proposed. We check up the performances using numerical results.

NAND flash memories have the advantages of fast access speed, high density and low power consumption, thus they have increasing demand in embedded system and mobile environment. Despite the low power and fast speed gains of NAND flash memory, DRAM disk buffers were used because of the performance load and limited durability of NAND flash cell. However, DRAM disk buffers are not suitable for limited energy environments due to their high static energy consumption. In this paper, we propose WAP-LRU (Write pattern Analysis based Placement by LRU) hybrid disk buffer management policy. Our policy designates the buffer location in the hybrid memory by analyzing write pattern of the workloads to check the continuity of the page operations. In our simulation, WAP-LRU increased the lifetime of NAND flash memory by reducing the number of garbage collections by 63.1% on average. In addition, energy consumption is reduced by an average of 53.4% compared to DRAM disk buffers.

Objectives The purpose of this study is to compare the representative differential diagnosis methods of blood stasis pattern used in Korea, China and Japan, and then to characterize each diagnostic method. Methods Through the journal databases, we have selected representative tools that were developed for differential diagnosis of blood stasis pattern in Korea, China and Japan. In order to characterize the selected check-lists or questionnaires, we investigated the number of items, contents, score calculation method, internal consistency, and accuracy of each selected tool. Results A total of four diagnostic tools were finally selected; quantitative diagnosis scale of blood stasis syndrome (QDSBSS), diagnostic criteria for blood stasis (DCBS), blood stasis questionnaire (BSQ), and blood stasis syndrome questionnaire (BSSQ). The key points in the differential diagnosis for blood stasis were different for each of the diagnostic tool. The key point was oral mucosa (including tongue) status in the QDSBSS. Meanwhile it was abdominal pain/resistance in the DCBS, and general pain in the BSQ. Accuracy of the QDSBSS, the BSQ and the BSSQ were powerful but all of them was not generalized. Conclusions Therefore, it is desirable to select and apply a plurality of appropriate tools according to the characteristics of the blood stasis patients.

Stereoscopic image generated by depth image-based rendering(DIBR) for surveillance robot and camera is appropriate in a low bandwidth network. The image is very important data for the decision-making of a commander and thus its integrity has to be guaranteed. One of the methods used to detect manipulation is to check if the stereoscopic image is taken from the original camera. Sensor pattern noise(SPN) used widely for camera identification cannot be directly applied to a stereoscopic image due to the stereo warping in DIBR. To solve this problem, we find out a shifted object in the stereoscopic image and relocate the object to its orignal location in the center image. Then the similarity between SPNs extracted from the stereoscopic image and the original camera is measured only for the object area. Thus we can determine the source of the camera that was used.

Regular dental visit of disabled patients is an important strategy for maintenance of oral health because of the lack of awareness of oral care. But there is limited information about follow up period in disabled patients after dental treatment. The aim of this study was to investigate the pattern of dental visit and dental management of special care needs patients according to the types of disabilities. A total of 140 patients who received dental treatment at Seoul National University Dental Hospital from 2010 to 2012 were reviewed. Patients were divided 3 groups according to the types of disabilities (disorder of external physical function, disorder of internal organ, psychic disability). Patient's characteristic, dental treatment performed, follow up period and frequency were investigated. The mean follow up period was 28.2 months and average frequency of visit was 3.69 times per year. There was no difference in period and annual visit between 3 groups, but significantly difference in cooperation with medical hospital in affiliation. Regular check-up was the most common dental treatment in all groups. In psychic disorder group, the proportion of sedative treatment was significantly higher than other groups. The results of this study provide information necessary for treatment planning and dental management of disabled patients.

In this paper, we introduce the low-density parity-check (LDPC) coded orthogonal frequency division multiplexing (OFDM) subframe reordering scheme for achieving equal combined power allocation in type I hybrid automatic repeat request (H-ARQ) systems and analyze the performance improvement by using the channel capacity. Also, it is confirmed that the layered decoding for subframe reordering scheme in H-ARQ systems gives faster convergence speed. It is verified from numerical analysis that a subframe reordering pattern having larger channel capacity shows better bit error rate (BER) performance. Therefore the subframe reordering pattern achieving equal combined power allocation for each subframe maximizes the channel capacity and outperforms other subframe reordering patterns. Also, it is shown that the subframe reordering scheme for achieving equal combined power allocation gives better performance than the conventional Chase combining scheme without increasing the decoding complexity.
