In this study, the convergent relation between perception of patient safety culture and safety nursing activity was investigated to prevent safety accidents and prepare data of nursing intervention for patient safety. Nurses in B City who signed on the written consent participated in this study between February 16 and 28, 2015. A total of 266 copies were collected and were analyzed using the SPSS 20.0 program. The mean score of patient safety culture was 3.60 on a scale of 0 to 5, and safety nursing activity, 4.28. The subcategory of perception of patient safety culture, which included the accident report frequency and patient safety level positively (+) influenced safety nursing activity. Therefore, effective communications and report systems in hospitals may be necessary to enhance patient safety culture. Education programs of patient safety should be developed and provided to nurses in hospitals to enhance the levels of patient safety management and their services.

Purpose : To evaluate the effectiveness and tolerance of postoperative external radiotherapy for patients with intracranial meningiomas. Materials and Methods : The records of thirty three patients with intracranial meningiomas who were treated with postoperative external irradiation at our institution between Feb, 1988 and Nov, 1999 were retrospectively analyzed. Median age of patients at diagnosis was 53 years with range of 17 to 68 years. Sites of involvement were parasagital, cerebral convexity, sphenoid ridge, parasellar and tentorium cerebelli. Of 33 evaluated patients, 15 transitional, 10 meningotheliomatous, 4 hemangiopericytic, 3 atypical and 1 malignant meningioma were identified. Four patients underwent biopsy alone and remaining 29 patients underwent total tumor resection. A dose of 50 to 60 Gy was delivered in 28-35 daily fractions over a period of 5 to 7 weeks. Follow-up period ranged from 12 months to 8 years. Results : The actuarial survival rates at 5 and 7 years for entire group of patients were 78% and 67%, respectively. The corresponding disease free survival rates were 73% and 61%, respectively. The overall local control rate at 5 years was 83%. One out of 25 patients in benign group developed local failure, while 4 out of 8 patients in malignant group did local failure (p<0.05). Of 4 patients who underwent biopsy alone, 2 developed local failure. There was no significant difference in 5 year actuarial survival between patients who underwent total tumor resection and those who did biopsy alone. Patients whose age is under 60 showed slightly better survival than those whose age is 60 or older, although this was not statistically significant. There was no documented late complications in any patients. Conclusion : Based on our study, we might conclude that postoperative external beam radiotherapy tends to improve survival of patients with intracranial meningiomas comparing with surgery alone.

Although the patient's problem with access to health information has been improved due to rapidly developing information technologies, such as the internet, some patients still do not have enough ability to understand, interpret, and analyze the health information. Given this view on the patient's asymmetric information problem, if a doctor provides sufficient effort to help patients understand and interpret medical information, the efficiency of patient's medical care use could be improved. This paper shows firstly that the patient's inefficient use of medical care originates from his information problems, such as the misperception of the effectiveness of medical care and secondly suggests that if the doctor makes sufficient effort to correct patient's information problems, the inefficiency can be ameliorated. This paper also suggests the manipulation of a doctor's payment method can lead a doctor to provide optimal level of efforts which can in turn lead patients to use the optimal level of medical care. With an optimal level of effort, a doctor can more easily achieve a patient's compliance with the newly recommended amount of medical care.

목적 : 환자의 호흡에 의한 움직임 및 부정확한 환자 자세 setup 때문에 3 차원 전신 정위 방사선치료,3 차원 입체조형 방사선치료 IMRT와 같은 방사선 치료기술에서 병소에 대한 정확한 표적 위치측정은 매우 어려운 실정이다. 그러므로 본 연구는 방사선 치료시 환자의 움직임을 최대한 고정시켜 줄 수 있으며 환자 자세에 대한 setup 오차를 감소시키고 환자 전신에 산재한 병소의 위치를 좌표화할 수 있는 전신 정위 프레임 제작과 제작한 프레임에 대한 고정효과 및 재현성을 나타내는 환자 자세의 setup 오차를 평가하는데 있다. 재료 및 방법 : 자체 제작한 전신 정위 프레임 구조는 CT 영상 촬영 가능성에 중점을 두고 병소 표적의 좌표실현 및 환자체형에 따른 다양성 그리고 프레임에 대한 견고성 및 안정성 확인에 초점화하여 제작하였다. 이렇게 제작된 전신 정위 프레임에 대한 방사선 투과율 측정 실험과 CCTV 카메라와 DVR(Digital Video Recorder)를 이용해 환자 자세 변화에 대한 영상을 획득하여 matlab으로 구현한 오차분석용 프로그램으로 환자 외부자세에 대한 오차 비교 평가하고 CT 촬영에 의한 가상표적 위치측정 실험을 수행하였다. 또 한 고정벨트 추가 사용으로 인한 환자의 고정효과 정도를 살펴보았다. 결과 : 제작된 전신 정위 프레임에 대한 방사선 투과율은 마그네트론 10, 21 MeV의 에너지에서 95, 96% 의 투과율이 측정되었고 30 $^{\circ}$. 60 。각도의 경사로 빔이 전달될 때는 90.3, 94.4% 가 측정되었다. CCTV 카메라를 이용하여 흉부 및 복부의 움직임을 촬영한 영상을 Matlab프로그램으로 구현한 오차분석 프로그램을 적용한 결과, 환자 자세에 대한 오차의 평균값은 흉부의 lateral 방향에서는 3.63$\pm$1.4 mm, AP 방향에서는 2.1$\pm$0.82 mm이었다. 그리고 복부의 later의 방향에서는 7.0$\pm$2.1 mm, AP 방향에서는 6.5$\pm$2.2 mm 이었다. 또한 표적 위치측정을 위해서 환자의 피부에 임의의 가상표적을 부착하고 CT 촬영한 영상결과, 프레임으로 가상표 적에 대한 위치를 정확히 파악할 수 있었다. 결론 : 제작된 프레임을 적용하여 방사선투과율 측정실험, 환자 외부자세에 대한 오차 측정실험, 가상표적 위치측정 실험 등을 수행하였다. 환자 외부자세에 대한 오차 측정실험 경우, 더 많은 Volunteer를 적용하여 보다 정확한 오차 측정실험이 수행되어야 할 것이며 정확한 표적 위치 측정실험을 위해서 내부 마커를 삽입한 환자를 적용한 임상실험이 수행되어야 할 것이다. 또한 위치결정에서 획득한 좌표값의 정확성을 알아보기 위해서 팬톰을 이용한 방사선조사 실험이 추후에 실행되어져야 할 것이다. 그리고 제작된 프레임에 Rotating X선 시스템과 내부 장기의 움직임을 계량화하고 PTV에서의 최적 여유폭을 설정함으로써 정위 방사선수술 및 3 차원 업체 방사선치료에 대한 병소 위치측정과 환자의 자세에 대한 setup 오차측정 결정에 도움이 될 수 있을 것이라고 사료된다.

Remote afterloading high dose rate brachytherapy (HDRB) is a new technology and needs new biological principle for time and dose schedule. Here, authors attempt to evaluate the technique and clinical outcome in 116 patients, 590 procedures peformed at Asan Medical Center for 3 years. From Sep. 1989 to Aug 1992, 471 procedures of intracavitary radiation in 58 patients of cervical cancer and 26 of nasopharyngeal cancer,79 intraluminal radiation in 12 of esophageal cancer, 11 of endobronchial cancer and 1 Klatskin tumor and 40 interstitial brachytherapy in 4 of breast cancer, 1 sarcoma and 1 urethral cancer were performed. Median follow-up was 7 months with range $1\~31$ months. All procedures except interstitial were performed under the local anesthesia and they were all well tolerated and completed the planned therapy except 6 patients. 53/58 patients with cervical cancer and 22/26 patients with nasopharynx cancer achieved CR. Among 15 patients with palliative therapy, $80{\%}$ achieved palliation. We will describe the details of the technique and results in the text. To evaluate biologic effects of HDRB and optimal time/dose/fractionation schedule, we need longer follow-up. But authors feel that HDRB with proper fractionation schedule may yield superior results compared to the low dose rate brachytherapy considering the advantages of HDRB in safety factor for operator, better control of radiation dose and volume and patients comfort over the low dose brachytherapy.

Background: Recent studies have suggested an association between chronic cough and gastroesophageal reflux. Our study aimed to assess the utility of a proton-pump inhibitor in unexplained chronic cough patients. Methods: Patients with chronic cough of unknown etiology were evaluated using a chest x-ray, methacholine challenge test, and an empirical trial of postnasal drip therapy. After excluding other potential causes of the cough, forty patients were included in the study and treated for 8 weeks with a proton-pump inhibitor. Results: Eleven and three patients in the first and second 4 weeks were lost to follow-up, leaving twenty-six patients finally included in the study. Of these patients, two were unimproved, eight partially responded to the proton-pump inhibitor and sixteen responded completely after the 8 week treatment. Conclusion: We suggest that empirical treatment with a proton pump inhibitor in all patients with persistent cough, which is not secondary to asthma or postnasal drip syndrome, represents a practical and simple approach to this ailment.

Purpose: This study was done to provide basic data for developing nursing interventions to enhance quality of life of pediatric patients with cancer (children and adolescents) by examining the quality of life and related factors. Methods: Participants were 134; 67 pediatric patients and 67 parents. The PedsQL$^{TM}$ 3.0 Cancer Module was employed to measure quality of life in the participants. The related factors included general and clinical characteristics of the participants. Results: Mean score for quality of life in the patients was 75.07, and mean score for patient quality of life as perceived by their parents was 64.40. Among the quality of life subscales, treatment anxiety had the highest score whereas nausea had the lowest score. Mean score in adolescent patients (13-18 years of age) was 71.62, lower than the 78.04 for child patients (8-12 years of age). Regarding general and clinical characteristics of the participants, there were no significant differences in the scores. Conclusion: The results indicate that there is difference in perception of quality of life between patients and their parents, and between children and adolescents and these differences should be taken into account when planning and providing nursing care.

This study is a descriptive research study to compare the safety perception between patients and nurses and to identify the factors affecting the nurses' safety management activities in tertiary hospitals. Data were collected with structured questionnaires from 147 patients and 147 nurses from a university hospital in J city, Gyeongnam, from July 24 to September 23, 2019, and analyzed using SPSS 23.0. The result showed that the patient's safety perception was significantly higher than the nurse's perception. The significant factors affecting patient management activity were nurse's educational level, position, effective communication, patient safety perception, and perception of importance on patient safety management. In the multiple regression analysis, knowledge about 'effective communication', and 'concerned about patient safety management', explained 54.8% of the nurses' patient management activity. Based on the results of this study, it is emphasized that nurses need to develop strategies to improve the communication and attention between patients and hospital members to improve patient safety management activities in tertiary hospitals.

This study is a descriptive research conducted to identify the factors influencing patient safety management activities of geriatric hospitals nurses and use basic data to prevent patient safety accidents. Subjects were 220 nurses and data were collected by questionnaires from february 1 to 28, 2023. Data were analyzed using t-test, ANOVA, Scheffe's test, Pearson correlation coefficients and Multiple regression analysis using the SPSS 29.0 program. Patient safety motivation was positive correlated with degree of patient safety(r=.41, p<.001), and degree of patient safety was positive correlated with patient safety nursing activity(r=.18, p<.01). Degree of patient safety(𝛽=.21, p<.001) and patient safety guidelines(𝛽=.16, p<.001) were main factors that affect patient safety nursing activity, and its explanatory power was 7.5%(Adj R²=.075, p<.001). For patient safety nursing activity, it is proposed to develop and apply a education program that strengthens practical training for effective coping after safety accidents along with risk prediction training to prevent before safety accidents.

Despite continuous efforts by healthcare institutions and professionals, incidents threatening patient safety continue to occur. Policies related to patient safety are being strengthened, and nursing students are recognized as key personnel in patient safety management. Identifying factors influencing patient safety management behavior can enhance competency in patient safety management and prevent and improve patient safety incidents. Therefore, the purpose of this study is to clarify the impact of nursing students' knowledge, attitudes, and performance confidence related to patient safety management on their patient safety management behavior. A descriptive survey study was conducted, and data collection targeted 138 fourth-year nursing students in K region from October 25th to October 28th, 2022. Statistical analysis was performed using SPSS 25.0 program. The research findings showed that knowledge, attitudes, and confidence regarding patient safety management were positively correlated with patient safety management behavior. Factors influencing patient safety management behavior were identified as patient safety management education experience (β=.22, p<.001) and confidence (β=.66, p<.001). Based on these results, it is suggested that educational programs aimed at improving patient safety management behavior among nursing students should focus on enhancing patient safety management education experience and confidence.
