A Critical Review of Viewpoints on the Time of the Origin of Hongqu(Red Yeast Rice)

Through a summary of the results of past research on the time of the origin of hongqu(红曲,red yeast rice),a critical review is made of multiple pieces of published evidence supporting the various viewpoints that hongqu originated from the Han,Wei,Jin,Tang,or Song dynasties.Based on a newly discovered textual comment by Kong Guangtao孔广陶(1832–1890)that rectified the mistake of mis-quoting“red wheat powder in Guazhou”(Guazhou hongzhi瓜州红)as“red yeast rice in Guazhou”(Guazhou hongqu瓜州红麯)in Entry into Learning(Chuxue ji初学记),a conclusion can be drawn that the evidence for a Han dynasty origin that has dominated for nearly forty years is not well-grounded,and proposes that Chinese hongqu originated in the Tang dynasty(618–907).

Discussion on the TCM Treatment of Hypertension from Pathogenetic Viewpoints of Modern Medicine

The ideal hypotensive agent should possess three essentials, i.e. to depress the blood pressure surely and steadily, and to block the renin-angio-tensin system (RAS)(1).

New Refinement Relations of Z Specifications for Multiple Viewpoints Oriented Requirements Method

In this paper we develop several new refinement relations of Z for multiple viewpoints oriented requirements method (MVORM). The original motivation is that we found the standard Z refinement relation is not adequate or correct when considering specifications that have temporal relationships of operations. The concept of temporal state variables is introduced into Z. Then new implementation relations are defined and new refinement relations are deduced, mainly for temporal state variables to process temporal relationships of operations. We use state transition systems to abstract the temporal state transitions. A simple example is used to show the procedures of MVORM. Finally some directions of further work are forwarded.

Two Generic Frameworks of Multiple Viewpoints Oriented Requirements Method and Their Comparison

Traditional requirements method has some problems when it is used for large distributed systems. Multiple viewpoints oriented requirements method (MVORM) is a new method for resolving these problems. This paper develops two generic formal frameworks of MVORM, framework based on refinement relation (FBRR) and framework based on implementation relation (FBIR). They are generic, because no assumptions are made about the development process or the formal description languages to be used. Three kinds of specification relations and three kinds of specification transformations are discussed over FBIR and FBRR. This paper also compares the equivalence between FBIR and FBRR. We point out that an equivalent FBIR can be found for any FBRR, but reverse transformation is not always possible. We think FBIR is better than FBRR on most cases.

Comparative Study on Differences of America-China Eco-Literature Viewpoints From the Perspective of Academic Compatibility

Facing the broad ＂eco-literature＂ subjects, this paper, first of all, taking eco-literature viewpoint and the theoretical connotation of eco-criticism viewpoint itself as the starting point, conducts a contrast study from the cultural origin-tracing on the American eco-literature viewpoint under the Western Bible vision and the Chinese natural eco-literature viewpoint of＂Oneness of Men and Nature＂ through the parallel comparison method; then from the visual angle of influential research is to further explore the academic compatibility in academic research： namely, the Western ecological literature consciousness begins to appear under the premise of the Western ecological civilization being destroyed, while the China＇s natural eco-literature of＂Oneness of Man and Nature＂ is based on a kind of unconscious affinity between people and nature in primitive age. Here it is necessary for us to point out that they cannot be mentioned in the same breath, because the modern ecological criticism is not the reduction of an ancient ecological thought, and also will lead to the academic non-compatibility in academic research. So only by correcting the people＇s misunderstanding in cognition, can we reach the unity of the natural ecological viewpoint and man civilized viewpoint so as to keep the harmony between human beings and nature.

Characteristic Insights on Industrial Cyber Security and Popular Defense Mechanisms

Due to the deep integration of information technology and operational technology,networked control systems are experiencing an increasing risk of international cyber attacks.In practice,industrial cyber security is a significant topic because current networked control systems are supporting various critical infrastructures to offer vital utility services.By comparing with traditional IT systems,this paper first analyzes the uncontrollable cyber threats and classified attack characteristics,and elaborates the intrinsic vulnerabilities in current networked control systems and novel security challenges in future Industrial Internet.After that,in order to overcome partial vulnerabilities,this paper presents a few representative security mechanisms which have been successfully applied in today’s industrial control systems,and these mechanisms originally improve traditional IT defense technologies from the perspective of industrial availability.Finally,several popular security viewpoints,adequately covering the needs of industrial network structures and service characteristics,are proposed to combine with burgeoning industrial information technologies.We target to provide some helpful security guidelines for both academia and industry,and hope that our insights can further promote in-depth development of industrial cyber security.

The untapped potential of scenic routes for geotourism:case studies of Lasocki Grzbiet and Pasmo Lesistej(Western and Central Sudeten Mountains,SW Poland)

A view is often more than just a piece of landscape,framed by the gaze and evoking emotion.Without diminishing these obvious‘tourismimportant’advantages of a view,it is noteworthy that in itself it might play the role of an interpretative tool,especially for large-scale phenomena,the knowledge and understanding of which is the goal of geotourism.In this paper,we analyze the importance of scenic drives and trails for tourism,particularly geotourism,focusing on their ability to create conditions for experiencing the dynamically changing landscapes in which lies knowledge of the natural processes shaping the Earth’s surface and the methods and degree of its resource exploitation.The issues are found in both wider and local contexts.A more detailed insight has been conducted on the basis of two,although in some sense peripheral,tourism regions from the Sudeten Mountains(southwestern Poland):Lasocki Grzbiet(a ridge)and Pasmo Lesistej(a small range).The subjects of the investigation were complex:the geotourism potential of selected viewpoints located on the most scenic routes(mostly paths and forest tracks)as well as the problems of maintenance,conservation,and protection of their educational value.Our work is based on desk and field research supported by results of GIS visibility analyses(conducted in the QGIS program).
