Purpose: This study aims to establish the basic directions of the modular airborne infection isolation(AII) ward. Considering a specific function and purposed use as a modular AII ward, it is a chance to derive an address of current modular technology by overview the limitation and improvement of the existing modular architecture. Methods: In addition to the literature analysis on the configuration system of mobile hospitals, research cases on the operational effectiveness of the domestic and foreign mobile construction systems are analyzed. Results: In order to meet the various and strict space guidelines of the AII ward and a chance to improve limitations of uniformed existing modulars, AII modular the negative pressurized care setting should be minimized a structural restriction for reflecting its system on a architectural plan. For this unique requirements, it could be possible to apply various space boxes called infill box which needs to secure a large-scale space. So, a rahmen structure system could be adaptable for this purpose. A dead space between beams of the rahmen structure is to be used for MEP installation. Partial separation, dismantling, and repair should be possible by separating the MEP and infill box from the structure. The infill box must keep 3.5m width under the current Road Traffic Act. Implications: It is necessary to utilize and develop an improved construction method that can reduce the problems of existing steel modular and PC modular.

The purpose of this study is to propose a design methodology to build temporary isolation rooms when infectious diseases suddenly occur in a certain region, such as the case of MERS-Cov in South Korea in 2015. Although most big hospitals usually have isolation rooms, they are expensive and dangerous to run such facilities on normal and typical days. To deal with these problems in this research, shipping containers are chosen as devices used to build the temporary isolation rooms near the original hospital. To do so, firstly, a prototype for the temporary isolation room was designed with the three part modules. The first part is for the medical team; the second part including the isolation rooms is for patients; the third part is for medical selection rooms to test the specimens. Secondly, the plan was compared with the MERS-Cov infection control guidelines. Finally this prototype is applied into the Yong-in Yon-sei severance hospital and then evaluated through a CFD simulation using STAR-CCM+(ver.9.06) for checking infectious bacterium movement in this prototype. The result showed that the prototype is effectively safe for patients tested as negative, patients waiting to be tested, and the medical team.

Purpose: As infectious diseases spread, hospitals have converted general wards into negative pressure isolation wards through remodeling. During the conversion process, there were limitations in converting the existing ward into an effective isolation ward due to its existing structure and mechanical system. To minimize these problems, this study proposes some general ward planning methods taking into account effective conversion to an infectious disease ward. Methods: Seven rapid conversion isolation wards have been analyzed in order to check their appropriateness as a negative pressured isolation unit. Then, general ward design planning methods that can minimize problems in rapidly converted negative pressured wards have been derived. Results: If general wards can be efficiently converted into negative pressure isolation wards, many isolation facilities can be secured effectively in a short period of time during a pandemic.

Purpose: The MERS(Middle East Respiratory Syndrome) outbreaks in Korea highlighted dramatically the failings of traditional hospital environment for controlling or preventing infections among both patients and healthcare workers. MERS is transmitted by droplets that can be airborne over a limited area. The point should be emphasized that MERS in South Korea was predominantly a hospital-acquired (not a community-acquired) infection, because approximately 93% of MERS cases were resulted from exposure in hospital settings. This paper tries to suggest the design guidelines of negative pressured isolation ward for the sake of proper control of severe respiratory infectious diseases. Methods: Literature survey on the design guideline and regulations of airborne infection wards in Korea, Europe U.K. and CDC of U.S. have been carries out. 4 special infection wards in Hongkong, Germany, Japan and Korea have been surveyed in order to make the best use of the experiences related to facility design and operations. Results: Operating system influencing the facility design, space organizations of infectious ward including required space and zoning, and circulations of patients, staffs and materials are proposed. Implications: The results of this paper can be the basic data for the design of the airborne infection ward and relevant regulations. Afterwards in-depth study such as the development of space standards for the single bedroom, locker room and so on could be explored.

Purpose: To decrease cross-infection, it's essential to analyze the spatial composition of the 'PPE doffing area'. Instead of solely relying on manpower standards, we should focus on responding to infectious diseases within the context of space planning. By doing so, we can lower the risk for healthcare workers' infection and ensure a level of safety in various environmental changes or new manpower input situations. Methods: This analysis is conducted specifically for facilities with negative pressure isolation wards. Additionally, interview surveys to obtain feedback from healthcare workers and incorporate their expertise into the design of the 'PPE doffing area' have been carried. Results: In a PPE doffing area, the standard spaces include a PPE doffing room, a shower room, and a clothing room. Depending on the facility environment or the level of infectious diseases, a Decontamination room or Anteroom can be optionally added. Healthcare workers who remove their PPE in the PPE doffing room should avoid re-entering the Negative pressure room. The shower room is often underutilized. When planning for a future PPE doffing area, an aisle space or passageway must be included even if a shower room is planned. Implications: This study examined the space used by healthcare workers rather than patients, with a focus on infection prevention through architectural planning rather than individual efforts. However, the investigation was limited to facilities that have been converted from general wards to negative pressure isolation wards, so it cannot be generalized to all infectious disease facilities.

Purpose: In response to the rapid spread of COVID-19 in 2020, the government supported facilities and equipment through the 'Urgent Isolation Ward Expansion Project'. Design and remodeling of efficient negative pressure isolation facilities had to be done in a short period of time, and the performance gap between facilities was very large because the types of hospitals and wards of existing medical facilities were diverse. In order to secure the stability of isolation wards between medical facilities and reduce the facility gap, guidelines for planning isolation wards considering the diversity of each hospital should be appropriately presented. In consideration of these points, this study aims to provide basic data for future remodeling guidelines for each plan type of the negative pressure isolation ward first. Methods: We analyzed the plans before and after the change of 13 case hospitals that performed the urgent care bed expansion project for COVID-19 confirmed patients. Before the remodeling, the current status of the facility was analyzed according to the type of corridor, the location of the nursing station, and the location of the elevator. After remodeling, the flow of medical staff and patients, the flow of entry and exit of clean and contaminated items, and the space of negative pressure and non-negative pressure areas. Results: The ward type was divided into three types according to the corridor type and room arrangement: double loaded corridor type with two side wards, race track type with one side ward, and race track type with two side wards. Based on these three types, the standard floor plan type of the isolation ward was proposed in terms of the location of the elevator bank and Nurse station. Implications: When the existing general ward is converted into a negative pressure isolation ward, this study can be a basic data to present customized guidelines for each ward type.

Recently, an unprecedented emerging infectious disease has rapidly spread, causing a global shortage of wards. Although various temporary beds have appeared, the supply of wards specializing in infectious diseases is required. Negative pressure isolation wards should maintain their function even after an earthquake. However, the current seismic design standards do not guarantee the negative pressure isolation wards' operational (OP) performance level. For this reason, some are not included in the design target even though they are non-structural elements that require seismic design. Also, the details of non-structural elements are usually determined during the construction phase. It is often necessary to complete the stability review and reinforcement design for non-structural elements within a short period. Against this background, enhanced performance objectives were set to guarantee the OP non-structural performance level, and a computerized tool was developed to quickly perform the seismic design of non-structural elements in the negative pressure isolation wards. This study created a spreadsheet-based computer tool that reflects the components, installation spacing, and design procedures of non-structural elements. Seismic performance review and design of the example non-structural elements were conducted using the computerized tool. The strength of some components was not sufficient, and it was reinforced. As a result, the time and effort required for strength evaluation, displacement evaluation, and reinforcement design were reduced through computerized tools.

Purpose: The negative pressure isolation ward is a key facility in preparedness and response to infectious diseases. For the sustainable operation of the facility, appropriate facility improvement is required. The experience of medical staff responding to infectious diseases in the COVID-19 pandemic provides effective informations for facility planning. Methods: The post occupancy evaluation (POE) was conducted by interviewing medical staff who is working on Nationally designated negative pressure isolation ward in general hospital. Floor plan analysis was conducted before field surveys for identifying facility characteristic and spatial composition. After that, field surveys were conducted at 3 hospitals, and interviews and fieldwork were conducted together. Results: It is necessary to increase the standard size of ward area from 15m² to 20m². The size of the doffing room has to be planned for accommodation of two or more people. Equipment storage, clean storage and waste storage also should be properly planned. There were almost no problems with the circulation in the ward. There was not enough space for medical staff. Implications: For a sustainable and safe negative pressure isolation ward planning, it is necessary to exploit learning from the medical staffs who have many experiences of coping with infectious diseases.
