  • Purpose : To compare the arterial and venous detection sites of triggering methods in contrast-enhanced-MR-venography (CE-MRV) for the evaluation of intracranial venous system. Materials and Methods: 41 healthy patients underwent CE-MRV with autotriggering at either the cavernous segment of internal carotid artery with an inserted time-delay of 6 seconds (n = 20) or the superior sagittal sinus without any timedelay (n = 21). 0.1 mmol/kg gadolinium-based contrast material ($Magnevist^{(R)}$, Schering, Germany) was intravenously injected by hand injection. A sagittal fast-spoiled-gradient-echo-sequence ranging from one ear to the other was performed (TR/TE5.2/1.5, Matrix $310{\times}310$, 124 sections in the 15-cm-thick volume). 17 predefined venous structures were evaluated on all venograms by two neuroradiologists and defined as completely visible, partially visible, or none visible. Results: The rate of completely visible structures were 272 out of 323 (84%) in the arterial triggering CE-MRV and 310 out of 340 (91%) in the venous triggering CE-MRV. The venous triggering CE-MRV demonstrated an overall superior visualization of the cerebral veins than the arterial triggering CE-MRV (Fisher exact test, p < 0.006). Conclusion: CE-MRV using venous autotriggering method provides higher-quality images of the intracranial venous structures compared to that of arterial.

  • This study was aimed to investigate the effects of Organizational Socialization Education Program on new nurse's job satisfaction, organizational commitment and turnover intention. This study was utilized a non equvalent control group post only design. The subjects of this study were total 76 nurses in total. Data were collected from 1st to 31th July, 2012. For the experimental group, 16 hours lectures on Organizational Socialization Education Program was given. Data were analyzed by Frequency, $X^2$, Fisher's Exact test & t-test. The findings of this study were as the followings: As proposed in the hypothesis, the subjects in the experimental group experienced more job satisfaction(t= -2.10, p=.039), more organization commitment(t= -2.68, p=.009), less perceived turnover intention(t= 4.65, p=.000), than those in the control group. The results of this study shows that Organizational Socialization Education Program is considered an effective program to improve job satisfaction, organizational commitment and to lessen turnover intention for new nurses. The Organizational Socialization Education program would be continually necessary to contribute to development of professional nursing occupation.

  • Objective: The purpose of this study was to evaluate the efficacy of frozen mixed double-embryo transfer (MDET; the simultaneous transfer of day 3 and day 5 embryos) in comparison with frozen blastocyst double-embryo transfer (BDET; transfer of two day 5 blastocysts) in patients with repeated implantation failure (RIF). Methods: A total of 104 women with RIF who underwent frozen MDET (n = 48) or BDET (n = 56) with excellent-quality embryos were included in this retrospective analysis. All frozen embryo transfers were performed in natural cycles. The main outcome measures were the implantation rate, clinical pregnancy rate, multiple pregnancy rate, and miscarriage rate. These measures were compared between the patients who underwent MDET or BDET using the chi-square test or the Fisher exact test, as appropriate. Results: The implantation and clinical pregnancy rates were significantly higher in patients who underwent MDET than in those who underwent BDET (60.4% vs. 39.3%, p=0.03 and 52.1% vs. 30.4%, p=0.05, respectively). A significantly lower miscarriage rate was observed in the MDET group (6.9% vs. 10.7%, p=0.05). In addition, the multiple pregnancy rate was slightly, but not significantly, higher in the MDET group (27.1% vs. 25.0%). Conclusion: MDET was found to be significantly superior to double blastocyst transfer. It could be regarded as an appropriate approach to improve in vitro fertilization success rates in RIF patients.

  • Purpose: The purpose of this study was to analysis the effects of a forgiveness nursing intervention program on hope and quality of life in woman with cancer. Methods: The used design was a nonequivalent control group design with pretest and post-test. Thirty patients diagnosed with uterine cervical cancer, breast cancer, ovarian cancer were recruited from a University Hospital in Busan, Korea. An experimental group (n=15) was given the forgiveness nursing intervention program, and a control group (n=15) was done a common nursing intervention. The period of data collection was from June 10 to September 10, 2004. The obtained data were analyzed using ${\chi}^2-test$, Fisher's exact test, t-test, and ANCOVA. Results: The first hypothesis, "The experimental group would have higher hope state than control group" was supported(F =16.967, p = .000). The second hypothesis, "The experimental group would have higher quality of life state than control group" was supported (F =4.850, p =.036). Conclusions: The findings showed that the forgiveness nursing intervention program was effective to increase hope and quality of life in women with cancer. Therefore, this program may be used for a nursing practice for cancer patients who are suffering from emotional distress.

  • Purpose: The purpose of this study was to investigate differences in vaccination status and awareness between influenza and pneumococcal vaccinations in the elderly. Methods: This cross-sectional study was used with a questionnaire. Data were collected from 107 older people over 65 years registered at one community center in December, 2012. The data were analysed with Chi-square, Fisher's exact-test, Wilcoxon Signed rank sum test, Mann-Whitney U test, and Kruskall-Wallis test. Results: There were significant differences in the experiences of vaccination and reason for unvaccination by vaccine types. The mean scores for awareness of vaccination were 1.81 (range 0~3) in influenza and 1.50 in pneumococcus (range 0~3). There was a significant difference in awareness by vaccine types (Z=6.12, p<.001). There was a positive association between influenza and pneumococcal vaccination awareness (rho=.236, p=.014). Conclusion: This study showed different vaccination status and awareness in vaccine types. It is necessary to consider vaccination status and awareness by vaccine types of the target population in the education program related to vaccination.

  • Purpose: Competency in physical assessment is an important component of nursing practice. However, some physical assessment skills are not being utilized within the current teacher-centered, content-heavy curriculum. This study was conducted to identify the effects of student-centered, self-directed learning in the physical assessment class. Methods: An experimental study with a post-test only control group design was used to compare an intervention group that was provided self-directed learning classes and a control group that was provided traditional lecture and practice classes. Competency in physical assessment, academic self-confidence, and learning satisfaction were evaluated. Collected data were analyzed using $x^2$-test (Fisher's exact test) and independent t-test. Results: Competency in physical assessment was significantly higher in the experimental group. However, academic self-confidence and learning satisfaction were not significantly different between the groups. Conclusion: The findings in this study indicate that self-directed learning can improve nursing students competency in physical assessment and that self-directed learning is a good education method to improve nursing students' competency in physical assessment during clinical practice and perform quality patient care by making active use of physical assessment skills.
