  • The NOx removal performance of the SCR process depends on various factors such as catalytic factors (catalyst composition, shape, space velocity, etc.), temperature and flow rate distribution of the exhaust gas. Among them, the uniformity of the flow flowing into the catalyst bed plays the most important role. In this study, the flow characteristics in the SCR reactor in the design stage were simulated using a three-dimensional numerical analysis technique to confirm the uniformity of the airflow. Due to the limitation of the installation space, the shape of the inlet duct was compared with the two types of inlet duct shape because there were many curved sections of the inlet duct and the duct size margin was not large. The effect of inlet duct shape, guide vane or mixer installation, and venturi shape change on SCR reactor internal flow, airflow uniformity, and space utilization rate of ammonia concentration were studied. It was found that the uniformity of the airflow reaching the catalyst layer was greatly improved when an inlet duct with a shape that could suppress drift was applied and guide vanes were installed in the curved part of the inlet duct to properly distribute the process gas. In addition, the space utilization rate was greatly improved when the duct at the rear of the nozzle was applied as a venturi type rather than a mixer for uniform distribution of ammonia gas.

  • This study derives problems of external space utilization site from on-site observation and questionnaire survey in order to suggest solutions for the problems. The main results are follows. First, fences as visual boundaries of apartment site play some negative roles - separation of space and heterogeneity of circumstance. This study suggests green fences to cure this problem. Second, residents want to change space use - ground to be used as green space or space for relaxation in stead of parking lots, elevator hall as social space, and underground as bike parks or health centers. Third, rooftop space, used as empty space or machine storage space, should be designed to be utilized as relaxation space by making easy to enter and exit.

  • In case of Senior Hospitals, meticulous care is required in both amount and quality of natural lighting because of the semi-long term residence of patients. Natural lighting has a huge impact on the physical and psychological part for the seniors. Likewise, natural lighting is an important factor considered for hospital design because it can also effect hospitalization period of patients. Research subject was K Senior Hospital which was determined as the courtyard-type building made to provide healing environment through natural lighting. Analysis was performed by dividing the space of K Senior Hospital into Central Treatment Department directly used by patients, Outpatient Department(OPD), Ward Department, Common Use Department. Research was carried out in two ways of integration value analysis using SPACE SYNTAX and illumination intensity analysis using ECOTECT. K Senior Hospital intended to actively let in natural light through courtyard and to make patients exposed to natural light when they walk along the circuit corridor built around the courtyard. This environmental consideration affected the utilization rate of Common Use Department and residence time of patients raising the average of Common Use Department on every floor. As a resuit of this study presenting type C and type D, part of four types of illumination intensity, takes higher percentage of almost every spaces compare to the others therefore K Senior Hospital was designed on the assumption of healing environment composition through natural light. The result of this research would be used meaningfully in the space programming phase of Senior Hospitals in the future. Utilization rate can be adjusted using illumination intensity value in the space that integration rate should be planed to be high. The use(purpose) of space and integration rate can be used as a guideline to set illumination intensity of natural.

  • Purpose: This study presents the results of the analysis on space utilization of kidney dialysis units in regional public hospitals, which plays a key role in local public medical services. The result aims to achieve safety from infection, allow comfort for the dialysis environment, and stability for medical support. The purpose of this study is to present fundamental data for architectural plans for the kidney dialysis unit, as well as to alleviate potential infectious diseases such as COVID-19. Methods: For research purposes, the investigation and analysis of space utilization were based on architectural floor plans, research papers and literature, related legal systems, and public statistics. Of the main 35 regional public hospitals, in regards to data accessibility, 15 facilities were selected to conduct the survey and analysis for the objective. Results: The space composition by area research results of kidney dialysis units in public hospitals are as follows: Firstly, most targets do not have required rooms in the access and support area, except for the hemodialysis beds in the treatment section. Secondly, the access area requires necessary room and space design that took into consideration of convenience and accessibility for patients. Thirdly, in regards to infection prevention and control, proper circulation and room plan is essential for storage and disposal of contaminated products and linen after use. For the treatment area, the arrangement plan needs to establish a visual connection between the isolation room, the nursing station, and the bed area. Additionally, consideration of circulation in the preparation, treatment, observation, examination, and all other rooms in the facility is required. Lastly, for the support area, the room is designed to consider adequate working and meeting spaces for the medical staff, consultation space for patients or guardians, separate storage and disposal of clean and contaminated items, and the storage of various equipment for dialysis. Implications: In preparation for the increase in chronic kidney failure patients and the spread of infectious diseases, such as COVID-19, the researched data demonstrates the basic guidelines for space composition of kidney dialysis units and the significant role of regional public hospitals.
