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〉

Control of nosocomial infections caused by the air is a serious problem. This research used the fluid dynamics software to analyze the effect of bio-aerosols emitted by the patients who have respiratory tract infections-influenza virus in a hospital outpatient department. The simulation of three kinds of architectural plan types is studied, including: (1) Case A：original plan type (circuited), (2)Case B (centralized); and (3) Case C (clustered). Based on the analyze on the bio-aerosols diffusing condition by wind velocity, air age, concentration contour and time of trajectory respectively, the results show that, all of these three patterns demonstrate highly spread of bio-aerosols.  
  In addition, we simulated Case A concerning the “Air curtain and Ventholes” to improve nosocomial infections, and found that the average wind velocity increases 112.04%, the air age shortens 81.91%, the pollution concentration decreases 76.47%, the pollution time shortens 41.92%, and the diffuse distances of pollution trajectory shorten 82.24%. The diffusion of the bio-aerosols is limited in a single sub-zone of the AC. It results in the decrease of the probability of nosocomial infections effectively, and it can be referenced in hospital architectural design.
