Recently, the number of confirmed cases has increased again with the new variant of COVID-19. Quarantine is recommended, especially to prevent the rapidly increasing spread, as environmental controls, such as minimizing contact with others, can increase safety. In addition, there are often cases in which the patient's condition cannot be confirmed from the standpoint of a guardian, such as visitation being prohibited under certain conditions. At this time, the sensor data values of oxygen, carbon dioxide concentrations, temperature and humidity, and alcohol, which are medical gases used in hospitals, are collected remotely using ZigBee wireless communication technology. Design a system that can be stored and monitored in a database. We propose an environmental monitoring system, which is a visualization system designed to allow hospitals to check and feedback data on the managed environment, and to give reliability to parents.

Purpose: We investigated the effects of a video-based education program for cerebral angiography on patients' state anxiety, uncertainty, nursing care satisfaction, and complications. Methods: The randomized experimental study included patients who underwent cerebral angiography at a university hospital in Bucheon, Gyeonggi-do between January 2023 and August 2023. Patients were assigned to the experimental group (n=50) and the control group (n=48). The program included video- and pamphlet-based education. The intervention included video-based education provided to the experimental group and conventional pamphlet-based education provided to the control group. Data were obtained pre-, post-, and 2-7 days post-intervention. Data were analyzed using the x²-test and the repeated measures analysis of variance test with the SPSS software, version 28.0. Results: The experimental group showed lower levels of state anxiety (x²=4.316, p=.038) and uncertainty (x²=3.974, p=.046) than the control group. However, we observed no significant intergroup differences in satisfaction with nursing care and complication rates. Conclusion: The results suggest that a video-based education program for cerebral angiography can effectively reduce state anxiety and uncertainty in patients undergoing cerebral angiography. Video-aided educational interventions can improve the quality of nursing care with regard to reducing state anxiety and uncertainty in patients who undergo cerebral angiography.

Background: Computed tomography (CT) scans in the Republic of Korea have spiked, reaching approximately 9 million examinations annually in 2017. CT provides significant medical benefits, but radiation exposure remains a concern. This study aims to analyze CT scans in Korea, as a basis study for radiation safety management. Materials and Methods: The raw data of total CT scans was obtained from the Health Insurance Review & Assessment Service and analyzed by CT scan type, patients' age and sex, and medical facility type. CT scans trends were analyzed considering the disease incidence. Results and Discussion: In 2017, CT scans accounted for 8,977,300. Usage per capita was 0.18 in males and 0.17 in females. CT scans increased with age until the 50- to 59-year-old groups, then decreased. CT scans were high in abdominal/pelvic (35%), chest (26%), and head (22%) regions due to higher disease rates. Head CT was most frequently used for infants and children. Abdominal/pelvic, chest, and spine CT were more frequent for older groups. The CT scans in the upper and lower extremities was high in child and juvenile groups. Chest and abdominal/pelvic CTs were higher in males, whereas spine, whole spine, and CT densitometry were higher in females. The proportion of CT scans of tertiary and general hospitals, hospitals, and clinics accounted for ≥80%, 13%, and 5%, respectively. Abdomen/pelvis, chest, and head/neck CTs were mostly conducted in tertiary and general hospitals, spine CT in hospitals and clinics, extremity CT in hospitals, and CT densitometry in clinics. Conclusion: The trend of CT scans varied based on the incidence rate for each patient's sex and age, and serious illness diagnosis by medical facility type. The results of this study provide data and guidance for evaluating the radiation exposure of the Korean population by CT and developing management policies for medical radiation safety.

Objective: Intraprocedural rupture (IPR) is a fatal complication of endovascular coiling for cerebral aneurysms. We hypothesized that contrast leakage period may be related to poor clinical outcomes. This study aimed to retrospectively evaluate the relationship between clinical outcomes and contrast leakage period. Methods: Data from patients with cerebral aneurysms treated via endovascular coiling between January 2010 and October 2018 were retrospectively assessed. The enrolled patient's demographic data, the aneurysm related findings, endovascular treatment and IPR related findings, rescue treatment, and clinical outcome were analyzed. Results: In total, 2,859 cerebral aneurysms were treated using endovascular coiling during the study period, with IPR occurring in 18 (0.63 %). IPR occurred during initial frame coiling (n=4), coil packing (n=5), stent deployment (n=7), ballooning (n=1), and microcatheter removal after coiling (n=1). Tear sites included the dome (n=14) and neck (n=4). All IPRs were controlled and treated with coil packing, with or without stenting. Flow arrest of the proximal balloon was not observed. Temporary focal neurological deficits developed in two patients (11.1%). At clinical follow-up, 14 patients were classified as modified Rankin Scale (mRS) 0, three as mRS 2, and one as mRS 4. The mean contrast leakage period of IPR was 11.2 min (range: 1-31 min). Cerebral aneurysms with IPR were divided into late (n=9, mean time: 17.11 min) and early (n=9, mean time: 5.22 min) control groups based on the criteria of 10 min of contrast leakage period. No significant between-group differences regarding clinical outcomes were observed after IPR (p=1). Conclusions: In our series, all patients with IPR were controlled with further coil packing or stenting without proximal balloon occlusion within 31 min of contrast leakage. There was no difference in clinical outcomes when the long contrast leakage period group and short contrast leakage period group were compared.

Background: The evolving healthcare environment necessitates changes in pharmacy education to meet these demands, with problem-based learning (PBL) being a promising approach. Methods: This study employed a single-group, repeated-measures design to evaluate the effects of PBL on the communication and problem-solving skills of fifth-year pharmacy students at S University. The course, which focused on pharmacy practice and communication, included 36 students who participated in structured pre- and post-intervention surveys, as well as self-reflection journals. The primary competencies assessed were problem-solving and communication skills. Data collection involved quantitative measures through surveys and qualitative insights from self-reflection notes. Results: Of the 36 students, 35 completed the pre-intervention surveys, and 27 completed the post-intervention assessments. Significant improvements were observed in problem-solving skills, including problem identification, information gathering, and planning. Communication skills showed overall improvement, though the differences were not statistically significant. Qualitative analysis of self-reflection notes revealed enhanced understanding of elderly patient care, increased responsibility, teamwork, and the importance of effective communication in pharmacy practice. Commonly identified themes included a heightened sense of responsibility, the importance of teamwork, and an appreciation for the multifaceted nature of pharmacy practice in elderly care. Conclusion: The PBL approach effectively enhanced students' problem-solving abilities and provided valuable experiential learning in pharmacy practice. The qualitative data indicated that students gained a deeper understanding of their roles and responsibilities, fostering greater motivation and teamwork. Further research should focus on broader applications across different institutions to validate these findings.

Purpose: The goals of this study were to identify the relationships among learning agility, grit, positive psychological capital, and nursing performance and to determine the impact of these factors on clinical nursing performance. Methods: Between November and December 2021, a descriptive survey design was conducted with a convenience sample of 260 clinical nurse participants from two regional hospitals. Data were collected using the Learning Agility Scale, Grit Scale, Psychological Capital Questionnaire, and the Nursing Performance Scale. Data from 248 nurses were analyzed using descriptive statistics, independent t-test, one-way analysis of variance, Pearson's correlation, and multiple linear regression analysis using SPSS 27.0. Results: Results revealed significant positive correlations between nursing performance and learning agility, grit, and positive psychological capital. Stepwise multiple regression analysis identified positive psychological capital as the strongest predictor of nursing performance, followed by work experience, learning agility, grit, and educational level. These variables accounted for 51% of the variance in nursing performance. Conclusion: This study underscored the importance of positive psychological capital, learning agility, and grit in improving nursing performance. Healthcare organizations should prioritize the development of these attributes among nurses. Implementing strategies to enhance these factors in nursing practice and education could improve nursing performance, potentially resulting in better patient outcomes and increased job satisfaction. Future research should explore specific interventions to cultivate these qualities and assess their long-term impact on nursing practice.

Purpose: This study aimed to understand the non-contact nursing experiences of clinical nurses during the COVID-19 pandemic. Methods: A qualitative research design applying thematic analysis was used. The participants were purposive sampled from three institutes: a tertiary hospital, a general hospital, and a residential treatment center in Seoul. Data were collected between December 2021 and January 2022 through individual in-depth interviews with 12 clinical nurses. The data were analyzed using Braun and Clarke's method to identify the meaning of the participants' experiences. Results: During the COVID-19 pandemic, the fields where the participants performed non-contact nursing included intensive care units and isolation wards of hospitals, a residential treatment center, and home cares. Their tasks in non-contact nursing commonly involved remote monitoring using digital devices or equipment, consultation and education. From their experiences performing tasks in these fields, the four theme clusters and nine themes were derived. The four theme clusters are as follows: (1) Confusion of nursing role; (2) Conflict due to insufficient support system; (3) Concern about the quality of nursing; (4) Reflection on the establishment of nursing professionalism. Conclusion: This study highlights the necessity for institutionalizing professional nursing areas, nursing education, and practical support by clarifying the purpose and goals of non-contact nursing and developing nursing knowledge through frameworks.

Objectives: Research on the general prescription patterns of insured herbal preparations in Korea has been limited. This study aimed to analyze prescription patterns of insured herbal preparations, utilizing the National Health Insurance Service (NHIS) sample cohort 2.0 data from 2010 to 2019. Methods: NHIS sample cohort 2.0 database, which represents a sample of 2.2% of the Korean population, was analyzed. We analyzed data related to prescriptions recognized as insured herbal preparations. Variables included patient demographics, diagnosis codes, prescription details, and healthcare institution characteristics. We examined trends over the decade, focusing on herbal formulae and single herb extracts. Results: During the study period, 275,358 patients visited Korean traditional medicine clinics and received at least one prescription of herbal preparations, representing 27.5% of the total sample. The number of prescriptions increased by 209%, from 34,621 in 2010 to 72,553 in 2019. Females accounted for 67% of these prescriptions, and 77% were for patients aged 70 and older. The top ten herbal formulae (TTHF), including Ojeok-san and Gungha-tang, constituted 76% of all prescriptions. Herbal formulae were used more frequently than single herb extracts, with certain prescriptions being commonly utilized. There was a notable focus on musculoskeletal disorders, with low back pain being the most common diagnosis. Conclusion: The study demonstrates a significant increase in the use of insured herbal preparations, primarily in small clinics and among the elderly. Prescription patterns showed a preference for specific single herb extracts and herbal formulae, with consistent trends over time. These findings provide valuable insights for future clinical research and policy development, particularly as herbal medicine's role in the national healthcare system continues to expand.

1. Purpose : This study is to present effective exposure conditions to acquire the best image of simple abdomen in Film Screen (F.S) system and Computed Radiography (C.R) system. 2. Method : In the F.S system, while an exposure condition was fixed as 70kVp, images of a patients simple abdomen were taken under the different mAs exposure conditions. Among these images, the best one was chosen by radiologists and radiological technologists. In the C.R system, the best image of the same patient was acquired with the same method from the F.S system. Both characteristic curves from F.S system and C.R system were analyzed. 3. Results : In the F.S system, the best exposure condition of simple abdomen was 70kVp and 20mAs. In the CR system, with the fixed condition at 70kVp, the image densities of human organs, such as liver, kidney, spleen, psoas muscle, lumbar spine body and iliac crest, were almost same despite different environments (3.2mAs, 8mAs, 12mAs, 16mAs and 20mAs). However, when the exposure conditions were over or under (below) 12mAs, the images between the abdominal wall and the directly exposed part became blurred because the gap of density was decreased. In the C.R system, while the volume of mAs was decreased, an artifact of quantum mottle was increased. 4. Conclusion : This study shows that the exposure condition in the C.R system can be reduced 40% than in the F.S system. This paper concluded that when the exposure conditions are set in CR environment, after the analysis of equipment character, such as image processing system(EDR : Exposure Data Recognition processing), PACS and so on, the high quality of image with maximum information can be acquired with a minimum exposure dose.

They need hospice care to palliate their total suffering in physical, emotional, social and also spiritual aspect through professional hospice team. To care their whole personal needs, hospice team must be a multi-discipline team which consists of medical doctors, nurses, social workers, pastors and volunteers. Recently those who die in hospice palliative care unit have trend to increase more than in home year by year. So it is necessary to develop the nursing intervention program to be performed by multi-discipline team approach for in-patient of hospice palliative care unit. The purposes of this study were to develop of wholistic hospice nursing intervention program for inpatient of hospice palliative care unit. The subjects of study were collected from 30 patients those who were over 18 years old and admitted in hospice palliative care unit of S hospital in P city with agreement in hospice palliative care in their terminal disease. The period of data collection was from December 15, 2003 to March 15, 2004. The result were as follows : 1. The result of Wholistic Hospice Nursing Program's development was as follow : A Wholistic Hospice Nursing Program was developed by me in this study is one of the service program for hospice palliative care unit. It was named as ‘Rainbow Program’ to be approached easily by hospice patients. The purposes of it are to improve the quality of life of the terminal patients with their dignity, to help them live in abundant and meaningful in their lives, to care them in peaceful in dying process with understanding them in whole personal, and also to palliate the grief and suffering of the bereaved. It was provided by hospice professionals(nurses, medical doctors, social worker, pastors, art therapists) and volunteers those who were educated in hospice for multi-diciplinary team approach to collaborate with each role play I 20-30 minuters of each through visiting their rooms individually and a place of hospice palliative care unit of S hospital in P city. The subjects of it were the terminal patients those who admitted hospice palliative care unit and their familes. with agreement in hospice palliative care in their terminal disease. The characteristics of it were multi-disciplinary team approach, whole personal care, individual care and total care according to their needs in their condition. The contents of it were pain control, symptom control, counseling patient, counseling family, hair cutting, hair shampooing, bed bath, recreation, taking a walk, event of culture(screen, recital, festival of praises, exhibition and so on), pastoral counseling, ritual service in bed, praying, service in bed, sing a worship praise, listening to the music, sharing remembrance of life, individual visiting music service(sing and praying), meditation Bible, art therapies(dance and drawing), social worker's counselling, confessing and sharing love and thanksgiving. The experimental group subjects participated in Wholistic Hospice Nursing Program which takes 120 minutes per session, total 10 sessions(total 1,200 minutes) altogether. In conclusion, this Wholistic Hospice Nursing Intervention can be used actively for whole personal well-being of the patients in hospice palliative in hospice palliative care unit and also applied in hospice practice as an useful model of multi-disciplinary team approach by hospice professionals.
