The purpose of this study was to explore traumatic experiences and posttraumatic growth of nursing students who were in clinical training. The data were collected from 490 nursing students at four nursing colleges with clinical training experience more than 1 year, from November 20th 2017 to December 20th. Collected data were analyzed through t-test, ANOVA, and $Scheff{\acute{e}}$ test with the SPSS/WIN 25.0 program, and qualitative data were analyzed by content analysis. 26.5% of the subjects had traumatic experiences in their daily life, 61.2% in the clinical practice. Their posttraumatic growth was scored 2.63 out of 5 on average. The contents of traumatic experiences were 'Violence experienced by medical staff','Negative perception of nursing care','Non-Educational Practical Environment' Clinical practice in a harsh environment, Witness of a serious patient, et al. The findings can be used as important basic data for the development of nursing practice education program for encouraging the posttraumatic growth of nursing students.

In several experimental models, estrogens protect neurons against ischemic insults. However, the recent clinical studies of hormone replacement showed negative results to prevent stroke. Therefore, optimal models to study estrogen replacement for neuroprotection are needed before its clinical ap-plication. Organotypic hippocampal slice under oxygen-glucose deprivation (OGD) has been established as a model of cerebral ischemia and has advantages to study drug effects. We investigated whether estrogen protected CAI neurons and affected activation of Akt (pAkt) in CAI region under OGD. Thus, rat hippocampal slices on day 7 of culture were treated with $17-{\beta}$ estradiol (E, 1 nM) for 7 days before 30 min OGD, and cell death of CAI neurons was quantified by propidium iodide (PI) staining and expression of pAkt was studied by Western blot and immunofluorescence. PI intensity in slices treated with E was significantly reduced 72 hour after OGD compared to that of non-treated slices (p < 0.05). E pretreatment also increased the expression of pAkt 72 hour after OGD compared to that of no treatment (p<0.01). These data suggest that estrogen pretreatment may rescue neurons from ischemic insults through the activation of Akt and also indicate that our model would be a useful alternative method to study the mechanisms and effects of estrogen replacement treatment for neuroprotection.

Objectives: This survey was done in order to find out how Korean medical doctors derive pattern identification for acupuncture prescriptions in treating low back pain in real clinical practice. Methods : The survey questionnaire was developed by the committee of experts who major in acupuncture & moxibustion or statistics for acupuncture clinical trial protocol development. The questionnaires were distributed via e-mail to 75 members of Korean Acupuncture & moxibustion society from March 26th to April 14th in 2009. 57 members completed answers, and the computerized data were analyzed by SPSS 17.0 statistical program. Results : 1.57 Korean medical doctors selected meridian pattern identification based on the course of the meridians(44.6%), visceral pattern identification(32.1%), pattern identification based on cause of disease(14.3%) as the most commonly used pattern identification methods for acupuncture prescription when treating low back pain patients in real clinical practice. 2. In meridian pattern identification based on the course of the meridians, gallbladder meridian of hypochondriac region(13.0%), bladder meridian of lateral low back region(11.2%), governer vessel of central low back region(11.7%) were selected 3. In visceral pattern identification, yang deficiency of kidney(20.2%), deficiency of kidney(19.3%), liver(16.7%), yin deficiency of kidney(14.0%), violence qi of kidney(8.8%), small intestine(7.9%) were selected. Conclusions : In our e-mail survey, Korean medical doctors answered that Meridian Pattern Identification based on the course of the meridians is the most often used diagnosis method. Visceral pattern identification, pattern identification based on cause of disease, meridian pattern identification based on symptom and pattern identification based on qi-blood-yin-yang theory in order of frequency used, were selected for low back pain diagnosis in real clinical practice.

Isolation and identification of anaerobic bacteria from blood cultures are still technically demanding procedures. Recently, with the use of gas liquid chromatography, the accuracy of identification is much improved. However, there has never been a satisfactory data analysis on anaerobic bacteremia in Korea. The authors evaluated both the clinical and the bacteriological data of 129 anaerobic bacteremias found at the Yonsei Medical Center during the period of 1973 to 1984. The most frequently isolated anaerobic bacteria were Bacteroides (52.7%), among which the major species was B. fragilis (38.7%). Incidence of anaerobic bacteremia by sex was 57% in male and 43% in female. Mortality was higg in groups below 1-year old and above 50-year old. The cause of death seemed closely correlated with the patient's age, general condition and the severity of the underlying disease. Various neoplasms were the most common (20%) underlying diseases predisposing the anaerobic bacteremia. Biliary tract was considered the most frequent route of infection in anaerobic bacteremia. The frequent clinical signs in anaerobic bacteremia were fever (65%), followed by liver function abnormality (29%), jaundice (20%) and hypotention(18%). When analysis of positive rate of blood culture was made on the patients from whom 4 cultures were done within 24 hours, it was found that 33% of the samples were positive. Isolation rate of anaerobic bacteria in thioglycollate medium was 83.8%, while it was 44% in Tryptic soy broth. Among the anaerobic bacteremia, 25.4% were polymicrobial infections with aerobic bacteria (92.5%), such as E. coli(33.3%). From these studies, it is concluded that B. fragilis is the most important causative organism in anaerobic bacteremia, with high fatality, particularly in those who have underlying diseases. The ports of entry are mainly biliary, gastrointestinal and female genital tract. Fever is the most frequent clinical sign. Single blood culture is not sufficient to detect all anaerobic bacteremia, therefore more cultures with optimal time interval are needed. The incidence of polymicrobial infection in anaerobic bacteremia is higher than that in overall bacteremia.

Objectives : From mechanism studies using animal models to high-level evidence based research such as randomized controlled trials or systematic reviews, various acupuncture studies have been performed. Nevertheless, the current research appears insufficient to satisfy clinicians' needs. We aimed at investigating clinicians' perception on the translational research and suggesting ways of symbiosis between basic research and clinical practice. Methods : Data were collected using a web-based questionnaire made available to Korean medicine doctors who were informed through social networking service or e-mail. The survey participants indicated their awareness of acupuncture research and their thoughts on the applicability of research in practice. Results : Forty-seven clinicians completed the survey. While most respondents agreed that acupuncture research is very important, only 40% of them answered that the results of acupuncture research are useful to their own practice. In more than half of those who responded to the survey, the current acupuncture research is not viewed as reflecting clinical practice very much. Respondents agreed that acupuncture research should be based on clinical practice, and they recognized the need to collect valid clinical data from real-world practice. Also, as many as 77% of clinicians had no scruple to participate in research programs. Conclusions : There is no doubt among practitioners that acupuncture research is necessary. More importantly, practice-based research remains essential in order to feed-back research outcomes to clinical practice. Communications and academic exchanges between clinicians and researchers can mutually benefit research and practice with better information, resulting in symbiosis.

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.

Purpose: This study aimed to describe nurses' experience in transition from new graduate nurses to professional clinical nursees in a hospital. Methods: Ten new clinical nurses working in a hospital participated in this study. Data collected through in-depth interviews were analyzed using phenomenology. Results: The analysis yielded five core category themes from new nurses for becoming a professional nurse: (a) beginning of hardship journey (b) feeling of inability in workplace (c) struggling hard to develop skills (d) enduring hardships by soothing oneself and peer support (e) beginning of an exciting journey. Conclusion: Over time, new nurses face many difficulties in transition to a professional status. To enhance the role development of new clinical nurses in hospital settings, nursing schools and clinical fields must teach and prepare them. Nursing schools should teach a strong theoretical base as well as nursing skills. In addition, in the clinical nursing department, education, teaching the integrated systems, staff development, support, evaluation, and feedback are needed for new nurses's development.

Background: Syncope is a common problem in children and adolescents. However, a large proportion of syncope cases have no underlying cause. Purpose: This study aimed to identify the factors affecting the severity of syncope using tissue Doppler imaging (TDI). Methods: This retrospective study included 61 children and adolescents with syncope who underwent echocardiography. The head-up-tilt test (HUT) was performed when there was a more severe syncopal event. We compared the echocardiographic findings between the execute HUT and nonexecute HUT, negative HUT result and positive HUT result, and normal electrocardiogram (ECG) and abnormal ECG groups. Data were analyzed using an unpaired t test post hoc analysis. Results: In the execute and nonexecute HUT groups, the odds ratios were 0.55 for medial E/E' (P=0.040) and 0.64 for lateral E/E' (P=0.049). Comparison of the results of the decreased, normal, and increased groups for lateral E/E' revealed a significant difference in the execution HUT and nonexecute HUT groups (overall, P=0.004; decreased vs. increased, P=0.003; normal vs. increased, P=0.050). Conclusion: Medial E/E' and lateral E/E' were decreased in patients with severe syncopal events. These findings suggest that the presence of left ventricular diastolic deterioration may cause hypoperfusion even in the absence of organic causes and, consequently, increase syncope severity and frequency. The TDI measured by echocardiography can be used as an index to predict syncope recurrence and/or severity.

Purpose: The purpose of this study is to review health-care program using the recent robotic horse-riding technology and its clinical effects for chronic low back pain. Research design, data and methodology: Recent clinical articles were determined under three inclusion criteria for in-depth review: 1) article that is published within 1 year, 2) article that includes the detailed explanation of health-care program using robotic horse-riding, 3) the article that deals with chronic low back pain during more than 6 months. Results: As a result, the finally-determined two articles demonstrated the clinical effects of robotic horse-riding statistically on pain intensity, low back muscle strength, spinal alignment, and fear-avoidance belief. Conclusions: After in-depth review, I concluded that health-care program using robotic horse-riding for chronic low back pain needs to be provided at low-intensity (e.g. less than 6km/h horse walking program) in the beginning of health-care for improving their motor control ability, then, at the increased intensity for strengthening core muscles.
