The objective of this study was to reduce the tumbling time with improved binding capacity for the manufacture of restructured hams(RHs) using a transglutaminase(TGase). The RHs had 73.9∼75.7% moisture, 3.63∼4.18% fat, 16.6∼20.6% protein with pH values of 5.95∼6.10 and water activity of 0.95∼0.96. No differences in hunter color values or functional properties were observed with the addition of 0.3% TGase or increased tumbling time. However, RHs without TGase had lower(p<0.05) textural profile analysis(TPA) values than those with TGase, regardless of tumbling time. Improved shear values were also observed with increased tumbling time only in RHs without TGase or with the addition of 0.3% TGase as well. This study indicated that 1 hr tumbling with the addition of 0.3% TGase improved the textural characteristics, as compared to the control 1(1 hr tumbling without TGase), resulting in similar shear values of the treatment, which tumbled for 4 hrs without TGase.

The purpose of this study was to verify the mediating effect of decentering between centrality of event and meaning reconstruction, based on relational loss experiences. To do so, surveys were conducted on 295 people(male: 109, female: 186) who would experience relational loss and be over 20 years old in the country using a questionnaire including a relational loss history checklist, the CES(Centrality of Event Scale), the Decentering Scale and the GMRI(Grief and Meaning Reconstruction Inventory). And the valid data were statistically processed using SPSS 22.0 program. The results of the study was followed. First, both centrality of event and decentering had positive corrleations with meaning reconstruction. Second, decentering completely mediated relationship of centrality of event and meaning reconstruction. Centrality of event had no direct effect on meaning reconstruction and the entire effect of centrality of event on meaning reconstruction was transmitted only through the path of decentering. Based on these results, limitations and implications of this study and suggestions for future studies were discussed.

The purpose of this study was to examine the usefulness of 3D reconstruction images in breast MRI by performing a quantitative comparative analysis in patients diagnosed with DCIS. On a 3.0T MR scanner, subtraction images and 3D reconstruction images were obtained from 20 patients histologically diagnosed with ductal carcinoma in situ (DCIS). The findings from the quantitative image analysis are the following: The 3D reconstruction images showed higher SNR at the lesion area, ductal area, and fat area that of the subtraction image. In addition, the CNR were not significantly different in the lesion area itself between the subtraction images and 3D reconstruction images.

Recently, many researches on RC(Reconfigurable Computing) with highly complex FPGA's and reconfigurable processors have been reported, and even some attempts for commercialization have been successful. In this paper, we introduce the design methodology for implementing DES crypto algorithm on small-capacity FPGA by using its dynamic reconfigurability and a system-level verification technique. Throughout this design project, we could evaluate the effectiveness of this approach, which is the dynamic reconfigurability of FPGAs makes the efficient trade-off between the performance and the cost robustly viable.

In the computerized tomography(CT), various filters are using in the reconstruction algorithm to reduce or eliminate the artifacts which are intrinsically induced by the imperfection of mathematical methods for reconstruction, lack of real informations about anatomic structures in the projection image, errors in data acquisition and so on. Hann filter was used to evaluate the filter effects on the elimination of reconstruction artifact in the CT image. The quantitative study was done by changing cut-off frequency of Hann filter from 0.1 to 0.9 with frequency increasement by 0.2. NPS analysis was fulfilled for the quantitative evaluation of filter effect.

지금까지는 영화나 3DTV같은 대형 모니터에 사용하기 위하여 입체영상이 제작되어 왔다, 하지만 최근 3D 디스플레이가 스마트폰이나 태블릿PC와 같이 작은 디스플레이 사이즈와 해상도를 가지는 휴대용 기기들에도 적용되어 다양한 형태로 보급되어 보다 많은 관심을 받고 있다. 하지만 모바일 기기와 같은 경우 영화와 고해상도 영상에서와 같은 3D 입체감을 느끼기 어려운 경우가 종종 발생한다. 본 논문에서는 작은 디스플레이 사이즈와 해상도를 가지는 모바일 기기와 같은 장치에서 3D 효과 향상을 위한 깊이맵 재구성의 방법으로 레이어의 개수를 제안하여 3D 효과를 향상 시키는 방법을 제안한다. 이를 위해 고해상도 영상에서 깊이값에 따른 레이어를 6개에서 2개까지 수를 줄여 깊이맵을 생성하였고 영상의 크기를 줄여 영상의 크기와 깊이 레이어에 따라 달라지는 입체 효과를 확인하였다.

Most of the online learning systems provide information that is based on the item difficulty what is custumized to learner. And the same learning process is performing to the same learning level learners. But, the degree of understanding of the same learning contents can be different even if the learner's level is same. Therefore, it is difficult to represent an effective learning experience because the learning is progressed by the determined difficulty of learning and the learning process even thought the provided content is difficult to understand. So we can control the learning difficulty during learning in order to escape from a uniform learning that online learning is provided. In this paper, we proposed a contents reorganization method for Self-Directed Learning. In this way, learners can understand their own level and customize the difficulty of learning. And then we expect the higher learning effect and satisfaction degree.

Structured lipid (SL) containing conjugated linoleic and caproic acid was produced from soybean oil through lipase-catalyzed reaction, and its oxidative stability was compared. When heated at $60^{\circ}C\;or\;150^{\circ}C$, soybean oil as control was more susceptible to oxidation than SL. When the antioxidants, such as ascorbyl palmitate, tea polyphenol, alpha-tocopherol, and rosemary extract, were added in SL, the induction periods of each antioxidant treats in SL were increased. The tea polyphenol showed the most effective antioxidant activity among them. When the emulsion form with SL was heated from oxidation, its oxidation stability was reduced compared to SL. The oxidation stability were also observed in photooxidation of SL.

The reconstruction problem in a low dose case requires some compromise of resolution and noise artifacts, and also some modification of filter kernels depending on the signal-to-noise ratio of projection data. In this paper, ail algorithm for the reconstruction of an image function from noisy projection data is suggested, based on minimum-mean-square error criterion. Modification of the falter kernel is made from information (statistics) obtained from the projection data. The simulation study Proves that this algorithm, based on the Wiener falter approach, provides substantially improved image with reduction of noise as well as improvement of the resolution. An approximate method was also studied which leads to the possible use of a recursive filter in the convolution process of image reconstruction.

The multimedia visualizational spreadsheet environment is shown to be extremely effective in supporting the organized visualization of multi-dimensional data sets. In this paper, we designed the visualization model that consists of the configurational 2D arrangement of spreadsheet elements at run time and each spreadsheet element has a novel framestack. As the feature, it supports 3D data structure of each element on the proposed model. It enables the visualization spreadsheet 1) to effectively manage, organize, and compactly encapsulate multi-dimensional data sets, 2) to reconfigure cell-structures dynamically according to client request, and 3) to rapidly process interactive user interface. Using several experiments with scientific users, the model has been demonstrated to be a highly interactive visual browsing tool for 2D and 3D graphics and rendering in each frame.
