Purpose: This study was a descriptive research to provide fundamental data in ensuring a high quality of nursing service needed by children's parent according to perception of uncertainty and care satisfaction of them between pediatric outpatient department and emergency room. Methods: For this study, 192 children's parents were questioned in a general hospital located in Busan from August 1 to 31. 2009. The collected data were scored by use of frequencies, $x^2$ test, t-test, AONVA, Pearson's correlation coefficient via SPSS/WIN 17.0. Results: With the compare of characteristics related to children's parents visiting emergency room and pediatric outpatient department, there were statistically significant difference in relation and age of parent, main caregiver, cause of arrival, and waiting time from arrival to procedure. The perception of uncertainty for parent in the emergency room showed significant difference to outpatient department. In nursing service, the highest score was category of professional skill and technic. In addition, overall parents' perceptions on providing information showed lower than any other nursing service. Last but not least, a significant correlation indicated between the perception of uncertainty and satisfaction of nursing service. Conclusion: Efforts to improve parent satisfaction for nursing service are needed to decrease their perception of uncertainty. Providing information and communication by nurses are necessary to improve quality of nursing service.

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.

Fires in operating rooms rarely occur. However, this type of disaster can complicate almost any surgical procedure. Fuel, heat and oxygen are related with fire outbreak. When ignition sources such as alcohol-based surgical preparation solutions are present, the risk of an operating room fire increases, and burns are more severe in such conditions. Many manufacturers recommend waiting at least three minutes after application to allow complete drying for reduce fire risk. There are a few studies regarding flame burns in the operation room, although most of these studies are related to preoperative skin preparation. However, alcohol containing solutions can be used occasionally for cleansing of the operation field after the surgery, therefore, the surgical team should pay attention to surgical fires, even if they have completed the operation successfully. We present our case of a post-operative flame burn and introduce some precautions that will reduce the risk of alcohol burns.

This Study was an attempt to estimate the optimum numbers of Operating Room Nursing Manpower by measuring the amount of service hours required by the patients in Operating Room in relation to the service amount actually provided by the nurses. The major concern of this study was placed on the measurement of Nursing Service Requirements by using the Operating Room (O. R) Patient Acuity System recently developed by M. M. Hart to classify the O. R. patients into four groups according to the degree of the complexity of operative procedure and some other elements which increase nursing activities in respect of patient care; Acuity IV group is the one requires nursing services most, on the other hand Acuity I requires least. nu sing The objectives of this study were as follows; 1. To analyze functions of the nursing personnel in O. R. by time unit and to estimate the average time a nurse can activate for productive functions. 2. To measure the actual amount of nursing times provided by nurses to the surgical patients. 3. To develop a patient classification system in order to measure the amount of Nursing services required by the patients. 4. To calculate an appropriate number of nursing manpower to meet the needs of the patients. In order to conduct the research both selected nurses and patients in 'S' University Hospital were Studied by utilizing the O. R. Patient Acuity System as well as the Classification Chart developed by Association of Operating Room Nurses (A. O. R. N) as a means of classifying functions of O. R. nurses. That is; Functions of the 10 selected O. R. nurses observed during the period of June 30 to July 4, 1986, whereas the amount of nursing services required by or provided to the 974 patients who had received surgeries during the period of June 9 to July 4, 1986. The results of this study were as follows; 1) The actual working hours per a nurse averaged 6.7 hours a day. 2) Each nurse's daily routine schedule consists of $71.4\%$ for Technical Functions, $16.1\%$ for Nonprodective Functions, $6.6\%$ for Assessment and Evaluation, $3.9\%$ for Overseeing and Supervision and the rest $2.0\%$ for Patient Preparation respectively. 3) Preoperative waiting time per a patient was 24.1 minutes on the average; for the first case was 10.7 minutes, whereas for the following cases was 32.0 minutes. 4) Total Operation time for the 974 patients during the period of observation for this study amounted to 2759.6 hours, weekly hour was equivalent to 689.9 hours, Whereas daily operation time averaged 130 hours. Meanwhile the average operation time per patient was 2.8 hours ; for the case of Acuity IV was 5.6 hours, 5. 1 hours for the case of Acuity III, 2.3 hours for Acuity II and 1.1 hours for Acuity I. 5) According to the O. R. Patient Acuity System, $64.5\%$ of the whole patients belonged to Acuity II, $23.7\%$ to Acuity III, 11. $3\%$ to Acuity IV and $0.7\%$ to Acuity I respectively. 6) Required amount of nursing times based on the preoperative waiting time and operation time was 7167.8 person hours, which showed that $5.5\%$ of them needed for preoperative nursing care, whereas the rest $94.5\%$ for intraoperative nursing care. In terms of the O. R. Patient Acuity System, $49.7\%$ of total nursing service requirements was needed for Acuity II patients, $27.4\%$ for Acuity III patients, $17.2\%$ for Acuity IV patients and $0.2\%$ for Acuity I patients. 7) The rate of the nursing services provided against the required nursing times was about $81.4\%$ on the average; some departments, like those of Plastic Surgery, Otolaryngology and Ophthalmology whose patients mostly belonged to Acuity II recorded hegher provision rate than average, whereas other departments of Thoracic Surgery. Neurosurgery and Orthopedic Surgery whose patients belonged to Acuity III and Acuity IV as well as Acuity II recorded lower provision rate than average. 8) Subsequently, required numbers of nursing manpower was 10.7 nurses additionally. Based on the above findings the following recommendations will be made; 1) this study recommends, develops. and adopts an accurate and realistic O. R. Patient Acuity System which can help measure the nursing service requirements objectively to elicit the rationales of allocation of nursing personnels. 2) this study proposes storongly place nurses who take the role of preoperative nursing care exclusively for the waiting patients in O. R. and shortening their waiting time by close communication between the designated O. R. and the ward.

A questionaire survey was conducted for patients who had been examined at the Department of Radiology to investigate the items that need to be improved. Brainstorming was also conducted by team members to suggest the tactics that can efficiently perform the QI activity by selecting the most frequently answered topics for the reduction of waiting time of x-ray examination. From September 2006 to November 2007, number of patients before and after conducting QI was compared for 3 months by each category differentiated by types of detailed causes. A patient case was set as one shooting for one patient. After conducting QI, the waiting cases before conducting QI were evaluated for the method of improvement for 3 month through the QI team discussion and conducted by following the improvement method for the next 1 month and the waiting cases were measured and the difference before and after the QI activity was compared in percentage. 1. When patient waiting cases were compared before and after conducting QI activity against the causes of repetition, it resulted in 3.9% of reduction effect. 2. When patient waiting cases were compared before and after conducting QI activity against the causes for the lack of guiding, it resulted in 1.1% of reduction effect. 3. When patient waiting cases were compared before and after conducting QI activity against the causes of miss-inputting prescription, it resulted in 1.1% of reduction effect. 4. When patient waiting cases were compared before and after conducting QI activity against the causes for emergency patients, patients with acute pain and discomfort patients, it resulted in 12.0% of reduction effect. 5. When patient waiting cases were compared before and after conducting QI activity against the causes for shooting overlapping of outpatients and hospitalized patients, it resulted in 4.7% of reduction effect. There are many factors to reduce the patient waiting cases in radiography. The first step is for radiology department to find these factors through QI, to improve them, which is the reason why the QI team is organized to perform the QI activities.

The most pivotal approach to improve subway indoor air quality (IAQ) is to examine the emission sources and particulate behavior. Therefore, the main objective of this study is to investigate the particulate behavior in the subway. In order to examine IAQ in the subway, a sampling and measurement campaign was carried out for 35 sites during the summer and winter seasons from May, 2005 to February, 2006. In case of 24 hour measurement, the mean concentrations ($PM_{10}$-24 hr) of platform and waiting room were $156.18{\pm}53.79{\mu}g/m^3$ and $111.00{\pm}53.31{\mu}g/ m^3$. Besides, as a result of 20 hour measurement, the mean concentrations ($PM_{10}$-20 hr) of platform and waiting room were $146.09{\pm}53.71{\mu}g/m^3$ and $99.08{\pm}42.77{\mu}g/m^3$, respectively. In general, $PM_{10}$-24 hr was higher than $PM_{10}$-20 hr, and both PM concentrations showed a high correlation coefficient (r=0.803). It was found that the $PM_{2.5}$ concentration ($l09.56{\pm}28.24{\mu}g/m^3$) in winter was higher than that ($83.66{\pm}57.82{\mu}g/m^3$) in summer.

$PM_{10}$ concentrations were measured at four monitoring sites at the Daechaung station of the Seoul subway. The four locations included two tunnels, a platform, and a waiting room. The outside site of the subway was also monitored for comparison purposes. In addition, the effect of the platform screen doors (PSDs) recently installed to isolate the $PM_{10}$ in a platform from a tunnel were evaluated, and a comparison between $PM_{10}$ levels during rush and non-rush hours was performed. It was observed that $PM_{10}$ levels in the tunnels were generally higher than those in the other locations. This might be associated with the generation of $PM_{10}$ within the tunnel due to the train braking and wear of the subway lines with the motion of the trains, which promotes the mixing and suspension of particulate matter. During this tunnel study, it was observed that the particle size of $PM_{10}$ ranged from 1.8 to 5.6 ${\mu}m$. It was revealed that the $PM_{10}$ levels in the tunnels were significantly increased by the PSDs, while those in the platform and waiting room decreased. As a result, in order to estimate the effect of ventilation system on $PM_{10}$ levels in the tunnels, fans with inverters were operated. It was found that the concentration of $PM_{10}$ was below 150 ${\mu}g/m^3$ when the air flow rate into a tunnel was approximately 210,000-216,000 CMH.
