  • Objective : The epidural fluid collection (EFC) as a complication of cranioplasty is not well-described in the literature. This study aimed to identify the predictive factors for the development of EFC as a complication of cranioplasty, and its outcomes. Methods : From January 2004 to December 2012, 117 cranioplasty were performed in our institution. One-hundred-and-six of these patients were classified as either having EFC, or not having EFC. The two groups were compared to identify risk factors for EFC. Statistical significance was tested using the t-test and chi-square test, and a logistic regression analysis. Results : Of the 117 patients undergoing cranioplasty, 59 (50.4%) suffered complications, and EFC occurred in 48 of the patients (41.0%). In the t-test and chi-test, risk factors for EFC were size of the skull defect (p=0.003) and postoperative air bubbles in the epidural space (p<0.001). In a logistic regression, the only statistically significant factor associated with development of EFC was the presence of postoperative air bubbles. The EFC disappeared or regressed over time in 30 of the 48 patients (62.5%), as shown by follow-up brain computed tomographic scan, but 17 patients (35.4%) required reoperation. Conclusion : EFC after cranioplasty is predicted by postoperative air bubbles in the epidural space. Most EFC can be treated conservatively. However, reoperation is necessary to resolve about a third of the cases. During cranioplasty, special attention is required when the skull defect is large, since EFC is then more likely.

  • The purpose of this study was to determine cervical cancer screening status of nursing students and to examine the effects of their knowledge, preventive behavioral intention on cervical cancer screening. This study targeted 192 nursing students from three universities in G. J City. The data were analyzed through frequency analysis, t-test, χ2-test, and logistic regression analysis using the SPSS/WIN 23.0 program. The factors influencing on the cervical cancer screening among nursing students were age, sexual experience, and preventive behavioral intention. In order to improve the cervical cancer screening rate, healthcare professionals must develop phased and sustainable education programs that enhance the intention for cervical cancer screening in schools and medical institutions for students to be provided from school-age years, which is a pre-sexually active period, to college years.

  • Background: Lumbar joint dysfunction is reported to be the main cause of lower back pain (LBP). The purpose of this study was to evaluate the effect of joint dysfunction on the postural balance of the lower hack and pelvis in different normal activities such as walking or stair management. Also it was studied whether the status of LBP (intensity and duration of LBP, length of treatment) contributes to die pelvic height difference (PHD) in various postures. Subjects: 28 patients with LBP and 32 normal adult volunteers, 60 years of age or younger, who came to the Community Health Center and orthopedic clinics in Incheon, South Korea. Methods: In order to determine the accuracy of the manual angulometer method in measuring the PHD, it was compared to the pelvic x-ray method in selected subjects. In the manual angulometer method, the arm of the angulometer was placed on the top of both iliac crests. The PHD was measured in static upright stance, then one-legged stance, on the affected leg or unaffected leg each time. Information regarding the disease status was obtained through interviews. Visual assessment scale was used to grade the intensity of LBP. Data analysis was performed using SPSS 10.0/PC program. Homogeneity between the two groups was tested by 2-test and t-test. To compare the PHD of the subgroups, we used t-test, F-test and two-way ANOVA. Relationships among dependent variables were analyzed by Pearson correlation analysis. Conclusion: In patients with LBP, lumbar joint dysfunction causes lumbar and pelvic postural asymmetry during normal activities.

  • This study was conducted to identify the factors affecting the depression and social anxiety of nursing students on happiness. The study subjects were 316 nursing students, and data were collected from October to November 2018. Data analysis was performed using descriptive statistics, t-test, one-way ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression analysis. The study showed that happiness and depression had negative effects on social anxiety, and depression and social anxiety had negative effects on happiness. Based on these results, it is necessary to prepare measures to reduce the depression and social anxiety experienced by nursing students in order to promote the happiness of nursing students. In the future, exploratory research should be continued considering the factors affecting the happiness of nursing college students in consideration of various factors and environments.

  • This study is a retrospective study attempted to determine the factors that influence the survival of patients with traumatic acute subdural hematoma. The study subjects were 207 patients with traumatic subdural hematoma who visited the emergency room from January 2017 to February 2019 at C University Hospital in G Metropolitan City. Data analysis was using the SPSS 23.0 program, and χ2-test, t-test, and logistic regression analysis. As a result of the study, the factors affecting the survival of the subjects were under disease, complications, and initial GCS. Therefore, it is necessary to establish a medical system to check the subject's history and to train medical staff to prevent complications. In addition, it is necessary to improve the transfer system so that the GCS of the subject can be measured from the stage before transfer to a medical institution and transferred to a hospital that can be treated quickly.
