ABSTRACT

Historic Japanese textiles from over 1000 years ago generally show marked deterioration and only very rare examples show their original forms and much information about textile reproduction has been lost. The replication of textile braids lacks systematic methodology and is still being practiced by only few individual braiding experts. The recreation of original braids as close as possible to original braids is a part of Japan’s intangible cultural heritage. The aim of this study is to clarify the decision-making procedure through which the braiding experts can decipher the original braiding structures. As a preliminary study of this project, interviews of a braid researcher and a replicating expert, Makiko Tada were performed regarding her working practices. It is important to clarify the braiding parameters for structural analysis such as the number of transits and the balance of ridges, and it became clear that the orientation of multiple colored threads plays an important role. The expert’s replicate works were also analyzed using a text-mining statistical technique to clarify the relationship of braiding parameters. The relationship between each braiding parameter and production method such as loop manipulation and Taka-dai became clear. As a result, the process of deciphering the original braid structure has been compiled in simplified workflows, which could contribute to the standardization and improvement in efficiency of replication of cultural property braids.  相似文献

李慧  胡吉霞 《图书情报工作》2020,64(18):114-125

[目的/意义] 针对包含单一类型知识单元的知识网络难以全面反映学科知识结构的问题，提出一种从多维度进行知识网络结构融合的方法，为学科领域知识结构挖掘提供借鉴。[方法/过程] 利用LDA及TF-IDF方法抽取学科知识单元，然后运用语义相似度和关键词共现分析方法构建3个学科知识子网络：主题网络、关键词网络和实体网络，并采用空间节点传递对齐方法对齐子网络节点，接着设计基于图卷积操作的自编码模型对知识节点进行表示，最后通过计算余弦相似度重构学科知识网络。[结果/结论] 实验部分以人工智能领域为例，构建融合主题、关键词和实体的学科知识网络并展开分析，实验结果表明，本文所提方法能有效地揭示学科领域研究内容和知识结构，为学科知识发现与组织研究提供有益参考。  相似文献

新时代背景下河南省优质高等教育资源配置研究     

《信阳师范学院学报(哲学社会科学版)》2018,(5):56-60

优质高等教育是一个国家和地区发展的重要引擎。坚持以人民为中心的发展思想,不断满足人民日益增长的享受优质高等教育的需要,是高等教育应该承担的社会责任。河南是一个人口大省和经济大省,但优质高等教育资源不足。基于对河南省高等教育历史的梳理和现状的分析,河南省要增加优质高等教育资源应创新高等教育投入体制,重点建设一批高水平大学,引进国内外优质高等教育资源,优化高等教育省内布局结构等措施,提升高等教育支撑创新驱动的能力,推动河南省由高等教育大省向高等教育强省转变。  相似文献   

北京冬奥会筹备对运动休闲基地建设的示范作用研究     

李杰桃 《广州体育学院学报》2020,(3):43-45

北京冬奥会雪上项目将在张家口市崇礼区进行，冬奥会筹备工作的重点也就集中在了这个过去名不见经传的小镇上了。虽然距冬奥会开幕还有近2年的时间，但崇礼区作为滑雪运动圣地已蜚声海内外，国外专业滑雪运动队将它作为训练基地外，国内业余滑雪运动者也从全国各地涌向这里。如今，张家口市整个经济被冬奥会激活了，其产业结构也已因崇礼区滑雪运动休闲基地实现了从农业经济向资源旅游经济的转型。虽然冬奥会筹备是国家级的大事，但张家口崇礼区的建设筹备仍然对全国休闲运动基地建设具有示范指导意义。  相似文献   

技术创新影响产业结构的空间传导路径分析     

江三良  纪苗 《科技管理研究》2019,39(13)

在理论分析技术创新影响产业结构优化升级路径的基础上，构建技术创新评价指标，引入三种不同类型空间权重，选取2000-2015年我国30个省级面板数据进行空间杜宾模型实证检验，结果表明：技术创新不仅促进了本地产业结构，还有助于邻近地区合理化发展，但对邻近地区高级化的抑制作用和促进作用并存；省域间技术创新和产业结构具有显著空间相关性，产业结构高级化存在正向溢出效应而产业结构合理化却有着负向溢出效应；技术创新能够通过一条直接路径和空间效应形成的三条间接路径作用于本地及其他地区产业结构；技术创新对产业结构的作用方向和强度存在较大区域差异。据此，加强技术创新提升产业结构结构的“先富带后富”，是可以通过政策引导实现的。  相似文献   

How to facilitate knowledge diffusion in complex networks: The roles of network structure,knowledge role distribution and selection rule     

《International Journal of Information Management》2019

The diffusion of knowledge within organizations provides opportunities for interpersonal co-operation, improves creative ability and therefore leads to competitive advantage. Focus of prior literature on knowledge diffusion has been on identifying factors that influence individuals' behavioral intentions to seek and share knowledge. However, knowledge diffusion as an enigmatic, emergent and organizational-level process is more than the simple aggregation of individual attributes and needs to be further investigated. Accordingly, this study focuses on three distinct system-level factors, i.e., architectures of connections among individuals, distributions of knowledge roles and designs of selection mechanisms and analyses their effects on knowledge diffusion. To be more specific, we examine three distinct knowledge roles: seekers, contributors and brokers. We also distinguish between three types of selection mechanisms: objective selection mechanisms, feedback-based selection mechanisms and random selection mechanisms. By conducting agent-based simulations on four representative networks, i.e., regular networks, random networks, small-world networks and scale-free networks, our results show that the optimal knowledge diffusion performance can be achieved on scale-free networks where all agents implement objective mechanisms and show characteristics of brokers. Moreover, our results (a) highlight the significance of brokers, (b) illustrate the superiority of objective selection rules and (c) demonstrate that scale-free networks provide an optimal framework for knowledge diffusion. Furthermore, we also find the interdependent relevance of these three factors to knowledge diffusion and propose a qualitative explanation of these findings.  相似文献

苏加福  杨涛  张娜 《科技管理研究》2019,39(15)

针对协同产品创新系统（CPIS）知识传播的特征，从组织知识活动微观层面对CPIS知识传播机理进行研究。在分析CPIS知识传播过程及影响因素的基础上，借鉴SIS疫病传播思想，将知识传播影响因素抽象为知识传播过程中的参数变量，构建基于元胞自动机的CPIS知识传播的K-SIS（knowledge-SIS）模型；以团队平均知识水平与知识水平标准差作为知识传播绩效的度量，利用K-SIS模型仿真研究知识粘性、主体间信任度、团队协同关联强度以及知识遗忘等因素对知识传播过程的影响情况，研究成果可为组织提高CPIS知识传播效率提供有价值的建议。  相似文献

于〓乐  程〓蕾 《广州体育学院学报》2019,(5):26-30

采用问卷调查和数理统计方法，研究了不同收入的居民对体育消费结构和体育消费需求的影响。结果表明，随着居民收入的增加，各类体育消费都呈现上升趋势，实物型体育消费增长速度变慢，观赏型体育消费和健身型体育消费增长速度变快，当居民年收入在10万以上时，观赏型体育消费和健身型体育消费开始急剧增加。制约体育消费需求的主要因素是居民的收入、体育消费的价格、体育消费结构和居民的可支配时间。  相似文献   

Production of green surfactants: Market prospects     

《Electronic Journal of Biotechnology》2021

Science has greatly contributed to the advancement of technology and to the innovation of production processes and their applications. Cleaning products have become indispensable in today’s world, as personal and environmental hygiene is important to all societies worldwide. Such products are used in the home, in most work environments and in the industrial sectors. Most of the detergents on the market are synthesised from petrochemical products. However, the interest in reducing the use of products harmful to human health and the environment has led to the search for detergents formulated with natural, biodegradable surfactant components of biological (plant or microbiological) origin or chemically synthesised from natural raw materials usually referred to as green surfactants. This review addresses the different types, properties, and uses of surfactants, with a focus on green surfactants, and describes the current scenario as well as the projections for the future market economy related to the production of the different types of green surfactants marketed in the world.How to cite: Farias CBB, Almeida FCG, Silva IA, et al.
