Purpose: In this study, we performed ventilation simulations for a standard isolation ward includingthree intensive care rooms, one anteroom(buffer room), and its recommended ventilationequipments. The purpose of this study is to predict outflow of pathogenic bacteria from patientbreath to verify the reliability and the safety of the isolation ward. Methods: We suppose threescenarios of the movement of medical staff. The leakage of patient’s breath to out of the ward ispredicted in these scenarios using CFD simulations. Results: The patient’s breath leakage rate to outof the ward in scenario 1 according to room air changes per hour(ACH : 6 and 12) is predictedto be 0.000057% and 0.00002%, respectively. The patient’s breath leakage rate to out of the wardin scenario 2 according to room air changes(ACH : 6 and 12) is predicted to be 0.00063% and0.00019%, respectively. The patient’s breath leakage rate to out of the ward in scenario 3, whichis the worst case(6 room air changes) is predicted to be 0.1%. Implications: Through the ventilationsimulation like that in this study, the reliability and the safety on isolation performance of variousplan of isolation ward are predicted quantitatively.

Purpose: This study aims to suggest the architectural planning guidelines for the nurse area andpatients’ convenient facilities design of the wards in central public hospitals of the communities. Methods: In order to suggest architectural planning guidelines, expert’s interview, field survey andanalysis of the floor plan have been conducted in this paper. Results: This paper presents room configurationsand space program, which determines the areas and structures of the spaces in thewards. Also it suggests the examples of floor plans which contains how to design nurse area andconvenient facilities of the patient in the wards. Implications: The result of this research would beuseful as a reference when the architect tries to design nurse area and convenient facilities of thepatient of the wards.

Purpose: The purpose of this study was to identify the role of the physical environment in task interruptionsin the healthcare settings. Many dangerous events such as airplane crash and medicalerrors are the result of human errors and, these errors are often the result of interruptions duringa critical task of professional workers. In fact, the physical environment that determines accessibilityand visibility among people affects interruptions significantly, but architectural studies have givenlittle attention to the management of interruptions. Methods: Therefore, the researcher reviewedresearch literature in other fields to find out how the physical environment affected interruptions. Many studies were from management, human factors, and health care, but few from architecture. First the author examined the impact of interruptions, second described the social context of interruptionsand the role of the physical environment. Results: Findings included that description of thephysical environment was not very clear in studies from management and human factors, while littlework had been done on interruptions in architecture. The author proposed study design that compensatedshortcomings of each field by combining approaches from management, human factors,and architecture. Implications: Unit design strategies such as distributed nurse stations can affectinterruptions and layout analysis such as space syntax analysis can evaluate visibility and accessibilityof floor plans in the preliminary design phase.
