A safety management rule of the diagnosis radiation system which opened a court 2006 February 10th was promulgated for safety of the radiation worker, patients and patients' family members. The purpose of this study is to minimize injury by radiation that can happen to patients and people around a sick ward when managing mobile X-ray system. This study analyzed sickroom environment of mobile X-ray examination and the statistical data of the Konkuk medical Information System(KIS) and the Picture Archiving Communication System(PACS). This study also investigated patient conditions, infection, relation information and related data, when the sickroom mobile X-ray examination is used. Through data analysis, many problems were expected such as restriction of space side, manpower and expense of business side, satisfaction degree decline of patient and protector of operation side. Therefore, we tried to restrict examination of multi bed sickroom, and to use treatment room in each ward to solve problem mentioned. As a result, the whole sickroom mobile X-ray examination rate decreased to near 50%, and mobile X-ray examination rate for inpatients decreased to more than 85%. This study shows that several attempts we did should be helpful for manpower, patients satisfaction and expenses. Also, they should protect patients in sickroom from unnecessary radiation exposure and could minimize inconvenience of patients and their family members from x-ray examination.

Purpose: Because of the recent COVID-19 pandemic, there have been many cases of using portable negative pressure unit to convert general wards into temporary negative pressure isolation wards. The purpose of this study is to analyze the indoor environment of the switching type wards. Methods: Field measurements and experiments were conducted in a medical facility. Air volume, wind speed and pressure difference were measured in non-occupant state. Dispersion tests were performed with gas and particle matter. Results: The pressure difference between the wards and the corridor was higher than -2.5 Pa in normal situation. However, in the gas and particle dispersion tests, it was found that there were concerns about the spread through leakages in low-airtight walls or ceilings. In addition, it was confirmed that the pressure imbalance in ducts through the non-sealed diffusers could cause back flow during portable unit operation. Furthermore, when there was a pressure difference between adjacent wards planned to be at same pressure level, the possibility of the spread through the leakages was found. Implications: When using portable units for making switching type wards, it is necessary to create airtight space and seal the non-operation diffusers. In case of operating the air handling unit, T.A.B must be performed to adjust the duct balancing.

This study was carried out to evaluate the effects of disinfection using environmental disinfectant after having assessed the extent of contamination through microbial culture testing and the Adenosine Triphosphate Bioluminescence method among the environmental management evaluation methods used for the environment in the hospital ward of patients infected by multidrug-resistant organisms. This study was conducted with the patient wards isolated due to multidrug-resistant organisms as the environmental surface. Specimens were collected from five locations including infusion pumps, IV poles, bedside cabinets, bed railings, keyboards, and blood pressure measurement cuffs. ATP and microbial culture testing were executed prior to, immediately after, and five minutes post-disinfection. According to the result contamination of the infusion pumps was statistically significantly reduced after disinfection. In addition, the bacteria before and after disinfection reduced in IV pole, bed railing, and keyboard. That is, regular environmental surface disinfection can provide safer environments to patients against infection. Therefore, it is necessary to establish guidelines including disinfection methods and intervals for environmental surfaces by evaluating the persistence of disinfectants at various institutions in the future.

최근 고령화 사회가 심각한 사회적 문제로 급부상하고 있으며, 이에 병원을 찾아 입원하는 비중이 이전에 비하여 높아지고 있다. 거동이 불편하거나 근력이 부족한 환자의 경우 스스로 거동할 능력이 다소 떨어지며, 낙상사고가 발생하면 부상 혹은 치명적일 경우 사망으로 이어질 수 있다. 하지만, 이들을 보살피는 간호 인력만으로 병원 내 모든 낙상사고를 파악하기에는 한계가 있다. 또한, 환자들의 낙상 탐지에 관한 연구는 지속해서 수행되어왔지만, 병원 내부환경에서의 낙상 탐지 연구는 부족하다. 이에 본 논문에서는 병원 내부환경에서 낙상을 탐지하기 위해 실제 병실에서 수집한 데이터로 YOLOv5 모델을 학습하여 환자 낙상 탐지모델을 구축 및 평가하였다.

Patients use the senses all the time, mostly simultaneously. Senses are never turned off even patients in serious condition use some of the senses. Space is the inexhaustible source of stimuli. So far we have thought that it is impossible to come up with a set of rules and guidelines that cover all the possible situations involving senses and when there have been usually no conscious coordination between different sensorial stimuli and the comprehensive perception of space always results from the engagement of combination of senses and other inputs based on knowledge and experience. This study concerns about patients' demand analysis through senses. The reflection of patients' demand to the ward planning can develope the healing environment.

This study was conducted to identify the effect of daylighting in hospitals on hospitalization time of patients and patients' outcomes in hospitals. Two major variations include orientation of hospital wards and the hospitalization times of various kinds of patients. Patients' data were obtained from two hospitals located in Seoul, Korea. The hospital buildings have north-facing and north-facing wards. The patients were classified according to the types of diseases and the orientation of the patient rooms. Then, statistical T-tests were applied in order to verify if natural light might shorter the hospitalization time of patients. The study also identified the types of diseases that were more responsive to the quantity of natural light in patient rooms. This information may be used as a basis for the development of guidelines for patient rooms in hospitals to achieve more effective healing environments. Likewise, the results may be applied to medical treatment buildings, recreational centers and hospital as well.

Introduction: This study was conducted to investigate patients' satisfaction with hospital services at a university hospital in G city. Methods: The subjects of this study were 92 inpatients and data were collected during the period from March to April 2003. The research tool used was a 24-item scale(Cronbach' a= .768) on patients' satisfaction with two subcategories of services: 18 items on hospital human resources(a= .722) and 6 items on hospital environment(a= .700). Data were analyzed through $x^2$-test, t-test and ANOVA using SPSS/PC. Results: The level of patients' satisfaction was $38.4{\pm}3.77$ on hospital services $27.6{\pm}6.14$ on hospital human resources, and $10.8{\pm}2.39$ on hospital environment on the average. Satisfaction related to hospital human resources was higher in male subjects (t = 4.15, p = .003) and in those who stayed longer than 15 days (t= 4.404, p= .039) than the others, and also higher in those who replied that all items related to hospital facilities are satisfactory except the parking lot. Satisfaction related to hospital environment was significantly higher in more educated subjects(F = 2.945, p= .037) and in those who replied that all items related to hospital facilities are satisfactory or appropriate except the parking lot and admission procedure. Conclusions: Length of stay and the level of accessibility and appropriateness of hospital facilities were found to be factors that have significant effects on patients' satisfaction.

This paper suggests detection system for the movement of patient on bed based on IEEE802.15.4 by using pressure pad and guard sensor. The system is designed to detect ordinary activities of patients on bed as well as patients' falling from the bed while sleeping at night. The node that is installed at bed sends data to gather when the pressure pad and sensor of guard detect patients' activities and falling. These data sent to gather are transmitted to monitor at help desk by TCP/IP communication. To remove unnecessary data that occurred due to switch chattering during tossing and turning, timer of MCU is used. Also, Communication module can change transmission power to apply this system to various environments of hospital room. Therefore, the nurse can take care of patients on bed in real time with data about patients' conditions.
