This study, which works to develop a method of focusing on A Quiet Dream by Zhang Lu, explored the structural differences of films and the changes in Zhang Lu's aim and perspective as noted in films, by a review to grasp his internal changes in texts and contextual factors. In A Quiet Dream, Zhang Lu made a filmic attempt that had never been made in the world of films prior to that date. He tried an aesthetic experiment on how films could reorganize the world, by using the effect of obscuring the boundary between reality and dream in films and generating a new narrative regarding filmic reality, actual reality, and the life and artistic truth of the Diaspora. Generally speaking, the changes in the narrative in A Quiet Dream seem to be his resistance against himself and the Diaspora. Thus, in the discussion about A Quiet Dream, relying on the external factors intervening in the relationship between the subject of creation and films is not a useful endeavor at this time. Consequently, it is noted that after settling down in Korea, Zhang Lu could directly approach the changes in the cultural position of films in multilayered ways, where films were the most dynamic part of his life. Due to the changes in the Diaspora, he could obscure the boundary for the first time in the world of films and experiment with how films could escape develop an interesting perspective that deviated from reality, and made a new goal to show new ideas regarding the individual's awareness of the world.

We introduce a class of multilevel recursive incomplete LU preconditioning techniques (RILUM) for solving general sparse matrices. This techniques is based on a recursive two by two block incomplete LU factorization on the coefficient martix. The coarse level system is constructed as an (approximate) Schur complement. A dynamic preconditioner is obtained by solving the Schur complement matrix approximately. The novelty of the proposed techniques is to solve the Schur complement matrix by a preconditioned Krylov subspace method. Such a reduction process is repeated to yield a multilevel recursive preconditioner.

In this paper, an effective skeleton method is proposed in order to obtain an enhanced digital image of skeleton line. The edge-detection method is applied in the preprocessing stage and after that, the modified Parallel method is applied to obtain the improved image of skeleton line. The existing parallel methods are Zhang, Lu and Wang, and Paul methods. Firstly, a parallel process method Is applied, and the proposed method is applied that the original is compared with the four neighbor pixels and four corner pixels of mask. In conclusion, the proposed method shows an improved connectivity and quality of skeleton line.

In watermarking schemes, the discrete wavelet transform (DWT) is broadly used because its frequency component separation is very useful. Moreover, LU decomposition has little influence on the visual quality of the watermark. Hence, in this paper, a novel blind watermark algorithm is presented based on LU transform and DWT for the copyright protection of digital images. In this algorithm, the color host image is first performed with DWT. Then, the horizontal and vertical diagonal high frequency components are extracted from the wavelet domain, and the sub-images are divided into $4{\times}4$ non-overlapping image blocks. Next, each sub-block is performed with LU decomposition. Finally, the color image watermark is transformed by Arnold permutation, and then it is inserted into the upper triangular matrix. The experimental results imply that this algorithm has good features of invisibility and it is robust against different attacks to a certain degree, such as contrast adjustment, JPEG compression, salt and pepper noise, cropping, and Gaussian noise.

The phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a tumor-suppressing lipid phosphatase that is frequently absent in breast tumors. Thus, the stability of PTEN is essential for tumor prevention and therapy. The ubiquitin-proteasome pathway has an important role in regulating the functions of PTEN. Specifically, carboxyl terminus Hsp70-interacting protein (CHIP), the E3 ubiquitin ligase of PTEN, can regulate PTEN levels. In this study, we report that BCL-2-associated athanogene 5 (BAG5), a known inhibitor of CHIP activity, reduces the degradation of PTEN and maintains its levels via an ubiquitylation-dependent pathway. BAG5 is identified as an antagonist of cell tumorigenicity.

The results of the study can be summarized as follows. The Shu-mu Da-wen was selected and compiled by Zhang Zhi Dong at the end of Qing Dynasty as a reading list for students preparing for the state examination and for the purpose of choosing the best from several versions. Whether it was compiled and edited by Zhang was in dispute. But it is almost certain that Zhang was the main editor because Shu-mu Da-wen showed his political, educational and scientific thoughts and knowledge distinctively. The followings are characteristics of Shu-mu Da-wen being compared with Si-ku Quan-shu Zong-mu Ti-yao. 1. In Jing-bu, the Confucian classics are divided into Zheng-jing Zheng-zhu and 'Lie-chao Jing-zhu Jing-shuo Jing-ben kao-zheng. Zheng-shi lei is divided into Zheng-shi fen he ke ben and Zheng-shi zhu bu biao pu kao-zheng. It is the special sorting method to include Du-ben lei in Jing-bu and Chu xue du-ben in Bie-lu in order to provide first learners for reading order. 2. Shi-bu included Gu-shi newly and Di-li lei is divided into Gu Di-li and Jin di-li in Shi-bu. Tian-wen Suan-fa lei is divided into Zhong-fa and Xi-fa in Zi-bu. Zhang distinguished between old books and contemporary ones to find out the origin and include newly published books in the East and the West. 3. Zhou-Qin zhu-zi is newly added to Zi-pu. In Ji-pu, Bie-ji and Zong-ji are categorized according to their style and period respectively. This show the new sorting method which added classifying system concerning academic development. It is the prominent feature in the compiling system to make Bie-lu and Cong-shu respective chapters. With those characteristics the Shu-mu Da-wen had been edited and published several times. It had a wide effect not only on compiling methods of cataloging afterwards and but also on classification systems before decimal classification was introduced in China.
