Purpose: This study identified the planning trends for formal and informal learning spaces in the college of medicine through literature reviews. And then, by the analysis of the actual condition of existing domestic facilities, It was organized the architectural planning baseline data and future directions for the formal and informal learning spaces in the college of medicine. Methods: This study was conducted using literature reviews on the existing medical education method and learning space planning. Subsequently on-site surveys and questionnaires were conducted at existing facilities. Results: In the past, learning space of the college of medicine was considered only a formal learning space such lecture rooms, labs. But lately it has been turned into a total learning concept that embraces shared learning spaces such as libraries, student spaces, amenities and common spaces such as lobbies and hallways. ① Formal learning spaces are composed of teaching and practice areas. Since It is the basic functions that comprise the college of medicine, this paper conducted a functional analysis based on the current operating system of the College of Medicine and provided baseline data on architectural planning such as function, layout, zoning, and detailed planning. ② The informal learning sharing space was divided into a library area and a student well-being and convenience area to analyze the real conditions of domestic medical college. In addition, by comparing the trends and differences in foreign medical colleges identified by literature analysis, this paper summarizes the need to revitalize informal learning spaces and their integration into formal learning spaces, architectural planning considerations, etc. Implications: the evolution of the learning method and the flexibility of the learning space bring about changes in the learning space.

Purpose: This study summarized architectural planning data for clinical practice spaces for CPX/OSCE and Simulation spaces, through analysis of domestic and foreign literature and a survey of domestic colleges of medicine. Methods: This study analyzed the architectural planning elements of the clinical practice spaces of the college of medicine, through a literature review on the clinical practice space and the survey of four recently established colleges of medicine. Results: ① It is desirable to plan the floor plan type for Simulation and CPX/OSCE spaces as a corridor-separated type that separates the circulations between students and staff (faculty). ② The simulation area arranges their practice rooms around the control space where the circulation of the staff is made. Conversely, it is desirable to arrange the CPX/OSCE rooms around the test waiting room where students enter. ③ It is desirable to separate access to the staff and students to allow student control, and to install various support spaces facing the staff corridor to secure the movement of equipment and the flow of evaluators. ④ In the simulation area, the equipment stored in the storage must be set in each room before the practice according to the setting of delivery or surgery like, and the equipment that has been removed must be back, so the circulation is short and does not intersect with the student circulations. ⑤ Debriefing rooms, seminar rooms, etc. are arranged in the staff area for review and discussion of clinical situations where practice and evaluation have been completed. Implications: It is important to configure an appropriate movement system and spatial zoning for each space for simulation and CPX/OSCE.

Purpose: The purpose of this study is to review the material handling system of the Airborne Infection Isolation Hospitals which is the one of the key elements of infection control and to improve the basic data for the planning and design of those facilities. Methods: Research was conducted by literature reviews and case studies for the material handling system of domestic and foreign Isolation hospitals. Results: The result of this study can be summarized into three points. First, a general isolation unit and a high level isolated unit need to be distinguished in terms of efficiency and safety. In particular, it is desirable that a high level isolated unit have to completely separate clean and soiled circulations, and soiled corridor should be installed by those means. By doing this, the medical staff can observe patient rooms and supply clean materials directly in the clean zone without wearing PPE, so that safety and work efficiency can be improved at the same time. Second, for the safe disposal of wastes, it is desirable to install a dedicated sterilizer per ward and sterilize it at least in the ward. In addition, It is desirable to install a central waste treatment room and a dedicated soiled corridor in consideration of the inadequate handling capacity and emergency situation. Third, the characteristics of material flow chart in the negative pressured isolation hospitals and the corresponding material handling system have been presented. Implications: Infection control is very important in safety, but it is necessary to respond to the symptoms of the patient.

Purpose: The purpose of this study is to provide an effective construction project cost estimation tool for preparing a business plan of healthcare facilities which can be practically used for development projects. Methods: In order to provide a tool for calculating construction project costs, this study analyzed the Building and Related Laws, the Building Technology Promotion Laws, the Ministry of Land, Infrastructure and Transport notifications and directives, the Ministry of Trade, Industry and Energy notifications, the detailed guidelines of the Ministry of Strategy and Finance, the Building Service Industry Promotion Acts, various certification standards, actual project budget calculation cases, etc. with advices from related experts. Results: 1) Construction cost is classified into construction costs, architectural design costs, supervision costs, incidental costs, and each sub-element. In particular, since there are many incidental cost items, essential items to be reviewed during planning are derived and costs are calculated according to appropriate consideration criteria. 2) Criteria for Payment calculation mainly applies the construction cost rate method or the actual cost fixed amount method in consideration of the characteristics and scope of work. Implications: There are many calculation factors that need to be applied to the construction project cost. Therefore, it is necessary to organize the calculation process more clearly.

Purpose: This study analyzed the architectural planning factors of the ward in infectious disease hospitals, such as functional unit planning, ward configurations, spatial compositions & circulation, and detailed architectural planning. Through these, the facility guidelines of infectious disease hospitals are summarized, focusing on the differences from the wards of non-infectious hospitals. Methods: This study was conducted by literature review of research reports, papers, design cases, and guidelines, based on the experiences of field surveys for infectious disease hospitals. Results: The result of this study can be summarized into a few points. 1) Infectious disease hospitals need to establish an operation plan with the concept of continuity of care, as an extension of existing facilities. 2) The types of ward configuration for infectious disease hospitals has many variables, so an appropriate type should be selected according to the hospital's operating policy. 3) Various spatial composition types of the ward can be planned by the arrangement of traffic cores and areas of patient groups. At this time, the main planning considerations are safety, efficiency, and comfort. 4) As elements of the detailed plan, It is necessary to consider the types & dimensions of patient rooms, the relationships between nursing stations & sub-stations, and supplementations of medical support functions & convenience facilities. Implications: Since there are many differences in function from the ward of non-infectious hospitals, appropriate facility guidelines for infectious disease hospital are required.
