Full scale fire suppression test by water mist system were performed in machinery engine room ($20m{\times}15m{\times}10m$) according to IMO MSC/circ. 1165. The K-factor and operating pressure were 2.4 and 80 bar respectively. To assess the prediction capability of numerical simulation, FDS simulation was performed at the same operating condition with the full scale experiment. It was found that FDS simulation had the limitation for the fire extinguishing time prediction but was able to predict the spatial temperature distribution.

Primary water stress corrosion cracking of steam generator tubings occur on many tubes in pressurized water reactors(PWRs), and they are repaired using sleeves or plugs. In order to develop proper repair criteria, it is necessary to know the leak behavior of the tubes, which have stress corrosion cracks. Crack development tests were carried out on the tubes at room temperature, and leak rate and burst pressure were measured on the degraded tubes at room temperature and a high temperature. No leakage was detected on the tubes where 100 % through wall crack developed, at 1560 psi, which is an operating pressure difference of pressurized water reactors(PWRs). In some tests, leak rates of the tubes increased with time at a constant internal water pressure. A test tube showed a very small amount of leakage at 2700 psi in a high temperature pressure test at $282^{\circ}C$, but it disappeared after the pressure increased slightly. Even cracks are 100 % through wall, they need to open in order to reach a certain amount of leak rate at the operating pressure difference.

Purpose: This study was a methodological research conducted to develop a clinical ladder system for operating nurses. Methods: Participants were 20 OR nurses, working in C Hospital, who had a mean tenure of 6 years and 10 months. Data collection consisted of 4 focus group interviews during May and June 2009. The content analysis method of Kim and Lee (1986) was used to analyze the data. Two clinical expert groups consisting of 16 nurses verified the content validity of the preliminary system from September 16 to 26, 2009 using Kim's tool (1999). Results: The final clinical ladder system consisted of goals, core values, and 4 domains of practice related to core values, which were defined as professional value, perioperative nursing practice, education/research, and collaboration/leadership. Eleven nursing competencies and 44 behavior indicators were included in accordance with the 4-step ladder. The 4 operation systems for the clinical ladder system were the promotion system, continuous learning system, reward system, and support system. Conclusion: The results indicate that nursing managers need to pay more attention to developing a clinical ladder system for nurses.

Background: The aim of this study is to examine the prevalence of musculoskeletal complaints in Swiss operating room (OR) nurses, and to investigate how work-family conflict, work interruptions, and influence at work are related to lumbar and cervical back pain. Methods: Participants in this correlational questionnaire study included 116 OR nurses from eight different hospitals in Switzerland. Results: We found that 66% of the OR staff suffered from musculoskeletal problems. The most prevalent musculoskeletal complaints were lumbar (52.7%) and cervical pain (38.4%). Furthermore, 20.5% reported pain in the mid spine region, 20.5% in the knees and legs, and 9.8% in the hands and feet. Multiple linear regression analyses showed that work-family conflict (p < 0.05) and interruptions (p < 0.05) significantly predicted lumbar and cervical pain in OR nurses, while influence at work (p < 0.05) only predicted lumbar pain. Conclusion: These results suggest that reducing the work-family conflict and interruptions at work, as well as offering opportunities to influence one's workplace, help to promote OR nurses' health.

We report a case of delayed chest wall reconstruction after thoracotomy. A 53-yearold female, a victim of a motor vehicle accident, presented with bilateral multiple rib fractures with flail motion and multiple extrathoracic injuries. Whole-body computed tomography revealed multiple fractures of the bilateral ribs, clavicle, and scapula, and bilateral hemopneumothorax with severe lung contusions. Active hemorrhage was also found in the anterior pelvis, which was treated by angioembolization. The patient was transferred to the surgical intensive care unit for follow-up. We planned to perform surgical stabilization of rib fractures (SSRF) because her lung condition did not seem favorable for general anesthesia. Within a few hours, however, massive hemorrhage (presumably due to coagulopathy) drained through the thoracic drainage catheter. We performed an exploratory thoracotomy in the operating room. We initially planned to perform exploratory thoracotomy and "on the way out" SSRF. In the operating room, the hemorrhage was controlled; however, her condition deteriorated and SSRF could not be completed. SSRF was completed after about a month owing to other medical conditions, and the patient was weaned successfully.

Purpose: The purpose of this study was to develop a valid and reliable instrument to explore and measure job satisfaction as perceived by perioperative nurses, specifically from the perspective of contemporary perioperative nursing in Korea. Method: Items (69) were developed from the responses to two open-ended questions by 168 perioperative nurses in one teaching hospital; (a) reasons that make work enjoyable, (b) reasons that make work unpleasant. Finally 55 items were selected, excluding items with lower correlation with the total scale. The instrument was completed by 885 perioperative nurses from 89 different hospitals nationwide who were attending the annual conference of the Korean Association Operating Room Nurses (KAORN), yielding a response rate of 95.6%. Results: Ten factors were extracted by factor analysis, which explained 60.0% of the total variance; Reliability and internal consistency were established (Cronbach's alpha=.95). A smaller sample of 39 perioperative nurses completed the instrument on two occasions, with a 2-week interval between. Mean scores were computed and two sets of scores were analyzed by Weighted Kappa (W-Kappa=0.680, p=.029). Conclusion: This instrument is a concise, highly practical and flexible tool, which can be used for the perioperative nurse in a wide range of hospital settings.

In accordance with the revision of "Special act on the safety control of publicly used establishments", this study is aim to measure the change in evacuation time due to whether safety facilities, etc. are installed of a room escape cafe business and kids cafe business(hereinafter referred to as "New publicly used establishments"), which were added as new targets of the publicly used business from June 8, 2022. In the case of new publicly used establishments or publicly used establishments whose owners are changed after the revision of the relevant laws, safety facilities, etc. are installed and maintained under the "Special act on the safety control of publicly used establishments", but in the case of existing businesses that have been operating even before the revision of the law, the business continues without safety facilities, etc. installed because the revised law is not retroactively applied. The purpose of this study is to compare and analyze the change in evacuation time by measuring the evacuation time to operating before the revision of the law to simulate evacuation at existing new publicly used establishments without safety facilities, etc. and measure the evacuation time at new publicly used establishments with safety facilities after the revision of the law

A century ago, cardiac injuries usually resulted in death. However, despite all the advances in medicine, these injuries still have high mortality and morbidity rates. In the present case, we describe a patient with a bullet injury to the right ventricle who survived at our hospital despite the limitations of our center with regard to modalities and equipment. A 30-year-old man was brought to our emergency department with a bullet wound to his left flank. He was hemodynamically unstable. After only 8 minutes in the hospital and without further investigations he was rushed to the operating room. During laparotomy, a clot was visible in the left diaphragm, which dislodged and caused extensive bleeding. The decision was made to perform a sternotomy in the absence of a sternal saw. An oblique 8-cm injury to the right ventricle was discovered following rapid exploration. It was repaired without the need for cardiopulmonary bypass surgery. After a few days in the hospital, the patient was discharged home. In the event of a penetrating cardiac injury, rapid decision-making is crucial for survival. Whenever possible, the patient should be transferred to the operating room, as emergency department thoracotomies are associated with a high mortality rate.

Background : This study was attempted to provide a basic information necessary for the development of measures evaluating perceived discomfort of the patients under local anesthesia and the developments of nursing intervention and nursing standard. Method : The study subjects were a convenience sample of 100 surgical patients under local anesthesia. The researcher visited the patients directly and explained the purpose of the study to them. Then they were asked to fill out questionnaires which were developed and structured by the researcher, under their prior permission. Out patient's data were collected at recovery room after operation. Results : Factor analysis on measures evaluating the patients under local anesthesia showed that the measures consisted of eight factors including "explanation", "humane treatment", "motion limitation", "pain", "no togetherness", "waiting", "the environment of operating room", and "unkindness". When analyzing each of the factors regarding their degree of contribution to perceived discomfort, it was found that "waiting" was highest in terms of the degree. According to general chara-cteristics of the sampled patients, the factor of "explanation" contributed to perceived discomfort more in male patients than female ones. Regarding parts of medical examination, the patients of otorhinolaryngology felt perceived discomfort most because of the factor of "pain". Conclusion : To relieve perceived discomfort the patients under local anesthesia require providing individually systematized nursing services which can reduce perceived discomfort according to each of the factors. In doing so, an unlimited attention and much effort should be given to realize CQI reaching the dimension of increase in comfort as well as decrease perceived discomfort.
