LIU XIUPING 한국중국문화학회 2018 中國學論叢 Vol.0 No.60

This paper mainly examines the semantic function of ‘de'in ‘de-construction' and the identity among three types of ‘de-construction'. Firstly, this paper sorts out and analyses the current research on the ‘de-construction', and puts forward some problems related to ‘de-construction', which are still unsolved and controversial. This paper demonstrates through examples that ‘de’ in ‘de-construction’ is not a ‘tense-aspect marker’. It can coexist with ‘le’, ‘zhe’ and ‘guo’. Finally, from the cognitive point of view, this paper introdu’es the concepts of ‘reality’and ‘irreality’ proposed by Langacker. It is considered that the three types of the ‘de-construction' has identity. The basic function of the ‘de-construction'is that the speaker protiling the reality as a gestalt and conveys it to the listener. The ‘de’ is a ‘reality protiling marker’ and the ‘de’ what is called Nominalization marker is a ‘entity protiling marker’ marker. There is identity between the two. 본고는 ‘的구문’에서의 ‘的’의 의미기능과 세 가지 유형의 ‘的구문’ 간의 동일성에 대해 논의하였다. 본고에서 우선 ‘的구문’에 대한 기존연구를 정리하고 분석한 다음, 현재까지 아직 해결되지 못하거나 논쟁의 여지가 있는 몇 가지 문제를 제기하였다. 그리고 예문에 대한 분석을 통해 ‘的구문’에서 ‘的’는 단순히 시제-상 표지가 아니라는 것을 입증하였고, ‘的’는 상 표지인 ‘了'、'著'、'過'와 모두 공기할 수 있다는 사실과 원인을 밝혔다. 마지막으로 본고는 인지적인 관점에서 Langacker가 제가한 ‘실상’과 ‘비실상’의 개념을 도입하여 ‘的구문’에 적용시켜 세 가지 유형의 ‘的구문’은 동일성을 가진다고 밝혔다. 그리고 본고에는 ‘的구문’의 근본적인 의미기능은 ‘화자가 실상을 하나의 게쉬탈트로 윤곽부여 청자에게 전하는 것’이라고 주장한다. 이에 따라 ‘的구문’에서 '的'는 ‘실상 윤곽 부여 표지’이고, 소위 명사화 표지인 ‘的’는 ‘실체 윤곽부여 표지’이며 이 두 개의 '的'는 서로 동일성을 가진다고 생각한다.

BACKGROUND: Cartilage, bone, and teeth, as the three primary hard tissues in the human body, have a significant application value in maintaining physical and mental health. Since the development of bacterial cellulose-based composite materials with excellent biomechanical strength and good biocompatibility, bacterial cellulose-based composites have been widely studied in hard tissue regenerative medicine. This paper provides an overview of the advantages of bacterial cellulose-based for hard tissue regeneration and reviews the recent progress in the preparation and research of bacterial cellulose-based composites in maxillofacial cartilage, dentistry, and bone. METHOD: A systematic review was performed by searching the PubMed and Web of Science databases using selected keywords and Medical Subject Headings search terms. RESULTS: Ideal hard tissue regenerative medicine materials should be biocompatible, biodegradable, non-toxic, easy to use, and not burdensome to the human body; In addition, they should have good plasticity and processability and can be prepared into materials of different shapes; In addition, it should have good biological activity, promoting cell proliferation and regeneration. Bacterial cellulose materials have corresponding advantages and disadvantages due to their inherent properties. However, after being combined with other materials (natural/ synthetic materials) to form composite materials, they basically meet the requirements of hard tissue regenerative medicine materials. We believe that it is worth being widely promoted in clinical applications in the future. CONCLUSION: Bacterial cellulose-based composites hold great promise for clinical applications in hard tissue engineering. However, there are still several challenges that need to be addressed. Further research is needed to incorporate multiple disciplines and advance biological tissue engineering techniques. By enhancing the adhesion of materials to osteoblasts, providing cell stress stimulation through materials, and introducing controlled release systems into matrix materials, the practical application of bacterial cellulose-based composites in clinical settings will become more feasible in the near future.

Upright Orientation of 3D shapes via Tensor Rank Minimization

In general, the upright orientation of a model is beneficial for human to recognize this model and is widely used in geometry processing and computer graphics. However, the orientation of the model obtained by existing technologies, such as 3D scanning systems or modeling, may be far away from the right orientation. In order to solve this problem, a robust and efficient upright method is needed. We observe that when the model is aligned with the three axes, the rank of the three-order tensor constructed by this model is the lowest usually. Inspired by this observation, we formulate the alignment of the 3D model with axes as a low-rank tensor optimization problem which is a global and unsupervised method. After the 3D model has been aligned with the three axes, some geometric properties can be used to pick out the best upright orientation from the six candidate supporting bases easily. The three-order tensor is constructed by voxelizing the bounding box of the 3D model, and then filling the voxel element with zero or one based on whether it contains the points of the model or not. The experimental results demonstrate that our method is robust, efficient and effective for all kinds of the models (manifold or non-manifold, man-made or non-artificial, or point cloud).

Starch is a major storage substance in cerealgrains, and starch biosynthesis is a complex process. In orderto elucidate regulation of the starch biosynthesis pathway, wescreened a series of rice (Oryza sativa L.) endospermmutants. In this study, we identified a floury white-coreendosperm mutant named floury endosperm12 (flo12). Theflo12 mutant exhibited loosely packed starch granules and alower thousand kernel weight compared to wild type. Semithinsections revealed that compound starch grains (SG) inflo12 interior endosperm cells were developed abnormally. Furthermore, amylose content was decreased, while totalprotein content was significantly increased in flo12 grains. Map-based cloning showed that FLO12 encodes rice alanineaminotransferase 1 (OsAlaAT1). OsAlaAT1 is highly expressedin developing endosperm. Subcellular localization showedthat OsAlaAT1 is localized in the cytosol. Moreover, theexpression of most starch synthesis-related genes wasdecreased, while most of the storage protein coding geneshad elevated expression levels in the flo12 mutant. Inaddition, overexpression of the OsAlaAT1 gene increasedgrain weight. In brief, we demonstrated that OsAlaAT1regulates carbon and nitrogen metabolism, which provides anew insight for the improvement of rice quality and yield.
