中医方剂与图集的转换方法

中药复方数据挖掘研究是将我国丰富的中药信息资源和现代最新信息技术相结合的重要内容,它意味着基于中医理论,利用知识发现技术,对传统中药新药、中医组方理论及规律、中药作用机制、有效成分构效关系等多个方面进行全面、系统的研究。图作为一种经典的数据结构,被广泛用于复杂数据结构分析与建模。文章探讨了图建模技术并实现了中医方剂与图集的转换。     

Semantic analysis in XTRA,an English — Chinese machine translation system

This paper concerns the resolution of lexical ambiguity in a machine translation environment. We describe the integration of principles of selection restrictions. Preference Semantics, and intelligent relaxation of constraints in handling lexical ambiguity. The approach differs from many previous MT systems in that it is more powerful than brute force systems, while more realistic than systems that assume a large degree of coded encyclopedia information for full understanding.

大气电场倒转与突发钠层及突发E层的相关性

突发钠层(Sporadic Sodium Layer, Na_S)是中高层大气金属层最为显著的一种现象,其发生机制目前尚无定论。突发E层(Sporadic E layer, E_S)是等离子体密度异常增大的薄层,被认为与Na_S密切相关。为进一步研究Na_S及E_S事件之间相关性及影响因素,利用中国科学院“子午工程”2010～2018年合肥科大站宽带钠荧光共振激光雷达观测结果,并结合武汉左岭镇站数字测高仪及九峰站大气电场仪数据,分析大气电场倒转(即北向电场)对Na_S以及E_S事件的影响。在统计的91例Na_S事件中,发生于大气电场倒转时的比例为20/91; 同时,在发生Na_S事件的事例中,E_S消失或中断的比例较大(14/20),表明E_S可能以提供钠源的形式转化为Na_S。此外,在分析武汉左岭镇站数字测高仪数据的同时进行概率统计,结果表明:当大气电场倒转时,E_S临界频率减小甚至消失的概率较大(187/242),少数情况下可能造成临界频率增大甚至激发E_S生成(55/242); E_S虚高消失比例为179/242,E_S不变比例为27/242,E_S上升比例为23/242。综上所述,大气北向电场在一定程度上对E_S事件的发生有抑制作用,并对E_S事件的发生高度有明显影响。最后,对一种与电场倒转相关的突发钠层机制也进行了讨论。     

基于感知驱动的纹饰矢量图评价方法

针对构建中华文化矢量素材库过程中如何评价矢量图质量优劣的问题,提出精确性、连续性和简单性三大视觉评价指标,并进行了量化分析. 首先,对矢量图进行解析,获取矢量图的文档对象模型,遍历文档树得到矢量信息;然后,结合格式塔心理学对矢量图的视觉误差、曲线连续性和纹饰图案的复杂度进行量化;最后,提出一种基于感知驱动的传统纹饰矢量图的评价方法. 结合视觉上的启发性规则,所提评价方法可提供3个量化指标用于多任务驱动矢量化系统中矢量图的自动评价、排序和筛选. 在纹饰矢量图数据集上对算法进行了仿真实验,结果表明,对矢量图的评价结果符合主流设计的视觉审美和期望.

The Role of Chronic Inflammation in Various Diseases and Anti-inflammatory Therapies Containing Natural Products

Chronic inflammation represents a long-term reaction of the body's immune system to noxious stimuli. Such a sustained inflammatory response sometimes results in lasting damage to healthy tissues and organs. In fact, chronic inflammation is implicated in the development and progression of various diseases, including cardiovascular diseases, respiratory diseases, metabolic diseases, neurodegenerative diseases, and even cancers. Targeting nonresolving inflammation thus provides new opportunities for treating relevant diseases. In this review, we will go over several chronic inflammation-associated diseases first with emphasis on the role of inflammation in their pathogenesis. Then, we will summarize a number of natural products that exhibit therapeutic effects against those diseases by acting on different markers in the inflammatory response. We envision that natural products will remain a rich resource for the discovery of new drugs treating diseases associated with chronic inflammation.

Gerontechnology acceptance by elderly Hong Kong Chinese: a senior technology acceptance model (STAM)

The purpose of this study was to develop and test a senior technology acceptance model (STAM) aimed at understanding the acceptance of gerontechnology by older Hong Kong Chinese people. The proposed STAM extended previous technology acceptance models and theories by adding age-related health and ability characteristics of older people. The proposed STAM was empirically tested using a cross-sectional questionnaire survey with a sample of 1012 seniors aged 55 and over in Hong Kong. The result showed that STAM was strongly supported and could explain 68% of the variance in the use of gerontechnology. For older Hong Kong Chinese, individual attributes, which include age, gender, education, gerontechnology self-efficacy and anxiety, and health and ability characteristics, as well as facilitating conditions explicitly and directly affected technology acceptance. These were better predictors of gerontechnology usage behaviour (UB) than the conventionally used attitudinal factors (usefulness and ease of use).

Practitioner Summary: Previous studies have not given much consideration to age-related health and associated abilities when examining acceptance of technology by the ageing population. By encompassing conventional technology acceptance constructs together with age-related health and ability characteristics, the present study was able to identify more factors affecting gerontechnology acceptance by older Hong Kong Chinese.     

元明青花红绿彩的研究与考证

青花红绿彩作为加彩器的一种,比传统的观点早一个朝代,根据明中青花红绿彩盖罐结合最新的窑址考古成果,得出元代的窑炉设计和釉面配方的缺陷,使元代青花红绿彩的生产和存世极少,明官窑中由于斗彩的出现,青花红绿彩在民间一直沿烧。与元代风格相近,只是到了后期风格才大变。
