This study aimed to develop the Traumatic Event Experience Scale in Perioperative Nurses (TEE-PON) and assess its validity and reliability. The TEE-PON underwent two distinct phases: scale development and scale evaluation. In the scale development phase, an initial set of 26 preliminary items was formulated through a comprehensive literature review and a focus group interview. Content validity was assessed by six experts, resulting in a refined total of 16 items after eliminating 10 items and modifying six others. In the scale evaluation phase, a survey was administered to 109 perioperative nurses. Following item analysis and exploratory factor analysis, the final scale emerged with four distinct factors encompassing 15 items. These factors were identified as ‘Conflict and violence in interpersonal relationships,’ ‘The death of a patient,’ ‘Witnessing the patient’s damaged body,’ and ‘Limitations of the work environment’. Correlation analysis between these sub-factors and post-traumatic stress, compassion fatigue, and job satisfaction confirmed the concurrent validity of the scale. The Cronbach’s α for the internal consistency of the finalized scale was 0.89, with sub-scales exhibiting values ranging from 0.69 to 0.87. The TEE-PON can be used as a valuable tool for assessing traumatic events experienced by perioperative nurses. Additionally, it can contribute to the development of intervention programs aimed at preventing post-traumatic stress disorder and compassion fatigue while concurrently enhancing job satisfaction.

This descriptive correlational study describes the relationship between collaboration among health care professions and nurses’ organizational commitment in the operating room. A cross sectional survey of nurses (N = 142) was conducted in March 2020. The participants were nurses with more than one year work experience in operating rooms at three university hospitals in Seoul and Gyeonggi-do. Collaboration among nurses was measured using the Nurse–Nurse Collaboration Scale, while collaboration between nurses and physicians was measured by the Nurse-Physician Collaboration Scale (NPCS). All analyses were conducted using the IBM SPSS Statistics, version 23.0 with independent t-test, one-way ANOVA, Scheffé test, Pearson's Correlation, and multiple regression. The results were as follows : The collaboration among operating room nurses was scored with an average of 2.87 out of a total of 4. Collaboration between operating room nurses to physician scored 3.47 average out of 5 total. Organizational commitment scored 3.24 average out of 5 total. The factors influencing the organizational commitment of nurses in operating rooms include collaboration among nurses and effective communication, as well as collaboration between nurses and physicians for decision-making regarding treatment and nursing care. The explanatory amount of general characteristic, nurse-physician collaboration, and nurse-nurse collaboration variables was 33%, 15%, 13% respectively. Based on these findings, to enhance collaboration among operating room nurses, there is a significant need for systematic education on communication skills and decision-making competencies, continuous research, and organizational efforts.

This study is a descriptive research study attempted to identify factors influencing depression of new nurses, focusing on job stress, self-efficacy, resilience, and social support factors of new nurses. The subjects of this study were 174 new nurses with less than one year of nursing experience, who worked at five university hospitals in the metropolitan area. A self-report questionnaire was used for the data collection of this study. The collected data were subjected to stepwise multiple regression to analyze the factors affecting depression using the SAS 9.4 program. As a result of the study, the average score of depression of the subjects was 13.01 out of 80, Factors influencing the subject's depression were identified including job stress(p<.001), self-efficacy(p=.044), resilience(p=.013), social support(p=.012), work department(p=.021), and work type(p=.001). It was found that the higher the job stress of the subject, the higher the degree of depression, while the higher the self-efficacy, resilience, and social support of the subject, the lower the degree of depression. In this study, it was confirmed that job stress, self-efficacy, resilience, and social support were factors influencing the depression of new nurses. In order to prevent depression of new nurses and actively manage with depression, it is suggested that arbitration programs for new nurses will be needed to reduce job stress of new nurses, strengthen self-efficacy, resilience and social support. It is also thought that strategies supporting for new nurses at the organizational level, such as the establishment of various social support systems, are needed

This study aimed to investigate the levels of perception of, knowledge of, and attitude toward patient safety and identify factors that affected patients’ attitude towards patient safety. In this descriptive study, participants included 196 patients hospitalized at a tertiary hospital in South Korea. Data were collected using self-reported questionnaires. Perception of and attitude towards patient safety were measure with a tool developed by Ahn Jin-ok, and the questionnaire for knowledge of patient safety was developed by researchers based on a literature review and validated by an expert group. Data were analyzed with Pearson’s correlation coefficients and multiple regression. The average perception of patient safety was 35.48(±6.80) out of 50; the average knowledge of patient safety was 84.33(±8.66) out of 100; and the average attitude towards patient safety was 36.88(±3.74) out of 50. The perception and knowledge of patient safety, level of hospital safety, and age were identified as influential factors explaining 13% of the variation in attitude towards patient safety. The results showed that the direct and indirect educational experience of patients may increase their perception and knowledge of patient safety that can influence their attitude towards patient safety. Therefore, patient education would be an important intervention to improve patients’ attitude towards patient safety. We recommend further studies with educational interventions for improving patient safety activities.

본 연구는 서울시 중학교에 재학 중인 학생 252명을 조사하여 남녀별로 국물음식을 통한 나트륨 섭취량의 차이를 조사하였으며, 실제로 배식받은 양과 섭취 형태에 따른 나트륨 섭취량을 계산하였다 본 연구에서 얻어진 결과를 요약하면 다음과 같다 1. 조사 대상자들의 성별은 남자 116명, 여자 136명, 학년 별로 1학년 86명, 2학년 77명, 3학년 89명이었다. 2. ‘국 없는 날’의 인식 여부에서 ‘국 없는 날’을 알고 있는 학생은 남자 58.6%. 여자 75.7%로 ‘국 없는 날’의 운영 횟수 질문의 응답으로는 1달에 1번으로 정확하게 알고 있는 학생은 남자는 55.2%, 여자는 62.5%로 나타났고, ‘국 없는 날’의 운영 이유로 ‘나트륨을 줄이기 위해서’라고 정확하게 답한 학생은 남자 61.2%, 여자 77.2%로 나타났다. ‘국 없는 날’의 인식 여부는 성별간의 유의한 차이가 있는 것으로 나타났으며, 여자가 남자보다 더 많이 알고 있는 것으로 나타났다. 학교 급식에서 저감화 나트륨 계획으로 운영되고 있는 ‘국 없는 날’을 정확히 알고 있는 경우는 59.1%의 학생만이 알고 있는 것으로 나타났다. 3. 나트륨 줄이기 교육을 받은 적이 있는 학생은 50명, 나트륨을 줄이기 위한 노력 여부는 노력한 적이 있는 학생도 53 명으로 나타나 전체 252명에서 채 20%를 넘지 않는 것으로 나타났다. ‘국 없는 날’의 운영도 나트륨 줄이기 교육의 일부임에도 불구하고, 나트륨 줄이기 교육 여부에서 남자 17.2%, 여자 22.1%만이 교육을 받았다고 답해 이에 관한 관심이 없는 것으로 나타났다. 이러한 인식실태는 ‘국 없는 날’의 운영만으로 나트륨 저감화 교육이 제대로 이루어지지 않는다는 것을 보여준다. 4. 학교 급식에서 제공된 국물음식의 섭취 형태에서 부대찌개는 건더기와 국물을 모두 섭취하는 인원이 71.8%로 가장 높았고, 그 다음으로는 설렁탕 69.8%로 나타났다. 우동은 건더기만 섭취하는 인원이 25.0%로 가장 높은 비율을 나타냈으며, 그 다음으로는 조랭이떡국 22.2%로 나타났다. 국물만 섭취한 경우에는 동태찌개 25.4%, 미소국 25.0% 순으로 나타났다. 북어국은 아예 국물음식을 섭취하지 않음이 36.1%로 가장 높아 선호하지 않는 것으로 나타났다. 5. 학교 점심급식에서 제공된 국물음식에 의하여 섭취하는 나트륨량은 국물음식 섭취행태를 고려한 경우 점심식사 한끼 국물음식 평균 379.6±183.9 mg, 고려하지 않은 경우는 556.8±190.6 mg으로 나타났으며, 메밀소바, 부대찌개, 우동순으로 높게 나타났다. 38가지의 모든 국물음식에서 나트륨 섭취량이 국물 섭취 행태에 따라 유의한 차이가 나타났다. 국물 섭취 행태를 고려한 경우와 고려하지 않은 경우에 나트륨 섭취량이 97.7~411.8 mg의 차이를 보이고 있었고, 평균 차이는 177.2 mg으로 나타났다. 몇 개의 음식에서는 차이가 있었지만 학교에서 제공된 전체 국물음식을 통한 평균 나트륨섭취량은 행태를 고려하던 하지 않던 남녀의 차이가 나타나지 않았다. 결론적으로 국물음식을 섭취 행태에 따라 섭취하는 나트륨 함량이 다르게 나타난 결과를 바탕으로 국물과 건더기, 국물만, 건더기만의 각각의 나트륨 데이터베이스를 이용하여 나트륨 섭취량을 분석하는 것이 필요하다.

We are currently developing the smart mosquito counter device (height 1080mm × width 560mm × diameter 320mm, 220V 60Hz 30W), which can attract the blood sucking female mosquitoes by emitting CO2 gas (300ml/min), can count the number of the captured mosquitoes by an infra-red beam area sensor, and can send the captured mosquitoes’ number through the CDMA module at real time. We operated the 8 – 16 devices with mosquito sensor networks and a server at the Youngdeungpo-gu areas in Seoul city of south Korea for three years (2011-2013) and we could efficiently control mosquitoes at the high mosquito density area based on the mosquito sensor’s data. We found that the accuracy of the device was about over 93% compared the real mosquito data and transmitted data by CDMA. We also found the water reservoir areas to control floods in Seoul metro city had relatively higher mosquito density than other normal areas, because those flat water areas were preferred by mosquitoes. Because our pest control office knew the mosquito occurrence peak times and areas from mosquito data transmitted by the mosquito sensor devices, we efficiently controlled mosquito larva and adults at the right time. We could accomplish very systematic mosquito control policy and we had the high credibility with the results. Based on the mosquito occurrence data, we selectively and scientifically controlled mosquitoes. Therefore, we reduced pesticide usage and saved annually pesticide expenses up to 2/3. Conclusively, if there is no mosquito, we don’t have to control mosquitoes.
