Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The Audiocardiography system is developed from hemodynamics theory. It measuring and recording the pulse wave on the wrist artery which contains various cardiovascular system information. Human fatigue is a physiological condition, which due to over time work or stressful environment. At fatigue state, the physiological adjustment changes which cause a variation to the cardiovascular system. Recurrence plot analysis is a powerful method to analyze non-linear dynamic system and to observe hidden characters. This research collects data through an non-invasive audiocardiography system proposed by Dr. Yu. In this thesis, data from two groups of participants are collected and PSD, Poincare’ plot and recurrence plot is adopted to analyze fatigue. Group one is long-term working type from restaurant workers with 16 participants all experience 8 to 10 hour of work. The analysis result shows that that HRV is lower and parasympathetic nerves are activated after work. Recurrence plot and its’ quantitative indexes show that the adjustment function of cardiovascular is better before work and much worse after work. The other group is short-term working type from car drivers with 15 participants experience a 60 to 75 minutes driving task though a particular route. The PSD shows that the diners are at a stressful state during the task. Recurrence plot and its’ quantitative plot shows that the HRV is higher and the cardiovascular is adjusting actively through the task.
