Objective : Postoperative seizure is a well documented complication of aneurysm surgery. The purpose of the present study was to analyze risk factors for postoperative seizure. Methods : Between January 1990 and December 1996, we performed craniotomy for ruptured cerebral aneurysms in 321 patients. Among them 206 patients who could be followed up for more than 1 year(range, 1 to 4.6 years) were enrolled to present study. All patients were treated with anticonvulsants for 3 to 18 months postoperatively. We analyze the incidence of postoperative seizure in different sex and age groups, and risk factors associated with postoperative seizures following aneurysm rupture. For statistical processing chi-square test and Fisher's exact test were used. Results : In the follow-up period of 1 to 4.6 years(mean, 1.8 years) postoperative seizure appeared in 18 out of 206 patients(8.7%). Mean latency between the operation and the first seizure was 6 months(range, 3 weeks to 18 months). The age of the patients has significant influence on the risk of seizure, it occurred more often in younger patients(p =0.0014). Aneurysm location in the MCA was associated with a significantly a higher risk of seizure(p = 0.042). Eight patients(19%) out of 42 patients who suffered delayed ischemic neurologic deficit(DID) developed seizure. Delayed ischemic neurologic deficit was associated with significantly a higher risk of seizure(p =0.019). Infarct and hypertension were associated with significantly a higher risk of seizure(p <0.05). pre- or postoperative intracranial hematoma(intracerebral or epidural hematoma) was associated with significantly a higher risk of seizure(p <0.0001). H-H grade, Fisher grade, Glasgow Outcome Scale of patients and timing of operation after subarachnoid hemorrhage had no significant relation with the risk of seizure. Conclusion : Factors associated with the development of postoperative seizure were middle cerebral artery aneurysm, delayed ischemic neurologic deficit, infarct on late postoperative CT scan, hypertension, pre or postoperative intracranial hematoma(intracerebral or epidural hematoma). Identification of the risk factors may be help to focus the antiepileptic drug threapy in cases prone to develop seizures. Prospective evaluation is indicated.

The purpose of this study was to examine the part-time work experience of nursing students and its effects on their interpersonal communication competence, self-efficacy and social skills. The study subjects were 362 nursing students in areas S, B, G and G. The relationship between the nursing students' part time work. experience and their general characteristics was analyzed by the Chi-square (${\chi}^2$) test and Fisher's exact test. The interpersonal communication competence originating from the general characteristics, self-efficacy, and difference in the social skills standard among groups were analyzed by the t-test, and analysis of variance (ANOVA). Among the 326 participants, 91.7% had part-time experience and 8.3% had no part-time experience. There was a significant relation between the part-time experience and economic level. Those having a low economic level were more likely to have part time work experience. The interpersonal communication and social skills of the students who had part time work experience when they were middle school students were lower than those who had such experience after high school. Further research is needed to identify precisely the advantages afforded by the part-time work experience of the nursing students.

Objective: The purpose of this study was to compare the shear bond strength (SBS) of brackets and microleakage of a tooth-adhesive-bracket complex bonded with a direct and an indirect bonding technique after thermocycling. Methods: Fifty non-carious human premolars were divided into two equal groups. In the direct bonding group a light-cured adhesive and a primer (Transbond XT) was used. In the indirect-bonding group, a light-cured adhesive (Transbond XT) and chemical-cured primer (Sondhi Rapid Set) were used. After polymerization, the teeth were kept in distilled water for 24 hours and thereafter subjected to thermal cycling (500 cycles). For the microleakage evaluation, 10 teeth from each group were further sealed with nail varnish, stained with 0.5% basic fuchsin for 24 hours, and examined under a stereomicroscope. Fifteen teeth from each group were used for SBS testing with the universal testing machine and adhesive remnant index (ARI) evaluation. Data were analyzed using the Mann-Whitney U test, Chi-square test, and Fisher's exact test. Results: There were no statistical differences on SBS and microleakage between the two bonding techniques. The indirect bonding group had a significantly lower ARI score. Bracket failures were obtained between enamel-resin interfaces. Conclusions: The type of bonding technique did not significantly affect the amount of microleakage and SBS.

This study is a descriptive evaluation of the differences in biomedical ethics consciousness, related knowledge, awareness, and attitude of nursing college students according to the completion of biomedical ethics education. The data were collected from 112 nursing students using self-report questionnaires and analyzed by t-test, Chi-Square test, Fisher's exact probability test and Pearson's correlation coefficient using SPSS 21.0. There were significant differences between the two groups in the sub-domains of biomedical ethics consciousness, artificial insemination, euthanasia and organ transplantation. The biomedical ethics consciousness was positively correlated with attitudes toward human tissue donation and transplantation, awareness of death, and awareness of hospice palliative care. The results of this study showed that after participating in the biomedical ethics education, nursing college students had statistically significant differences in the consciousness of artificial insemination, euthanasia, and organ transplantation. Moreover, the consciousness of biomedical ethics was related to attitude toward human tissue donation and transplantation and awareness of hospice palliative care. Based on the results of this study, we would like to suggest the need for development of various curricula related to death, hospice palliative care, human tissue donation and transplantation in the biomedical ethics curriculum. In addition, as the study was conducted in a single college, it is difficult to generalize the results; therefore, additional studies at different facilities are recommended.

The purpose of this study was to examine the effects of health program s on hypertension in a public health center located in Y-si. Most interesting were the effects on hypertension-related knowledge, self-care behavior, quality of life, and physiological parameters for hypertensive patients. Nonequivalent control group pretest-posttest design was employed. A total of 48 patients with hypertension living in Y-si were assigned to either the experimental group (n=23) or the control group (n=25). The experimental group was provided with an 8-week health program on hypertension between August 31 and October 23 in 2015. Data were analyzed with SPSS/WIN 21.0 using descriptive statistics, ${\chi}^2$-test, Fisher's exact test, and t-test. The result indicated a significant difference between the experimental group and the control group with respect to the scores of hypertension-related knowledge (t=-3.76, p<.001), self-care behavior (t=-3.33, p=.002), physiological parameters, including systolic blood pressure (t=6.27, p<.001) and diastolic blood pressure (t=4.70, p<.001), total cholesterol levels (t=3.08, p=.003), and Abdominal circumference (t=2.52, p=.015). We conclude that the self-group program on hypertension has a significant effect on the change of hypertension-related knowledge and self-care behavior for hypertensive patients.

This study is a nonequivalent control group pre- and post-test design research whose purpose was to determine what effects the pre-operation provision of information has on the anxiety and uncertainty of mothers with a pre-school child of tonsillectomy and nursing satisfaction after the operation. Data were collected from mothers whose child underwent tonsillectomy at S general hospital. For the collection, those mothers were divided into the experimental and control groups, respectively consisting of 19 and 20 members. The experimental group was provided general education about the operation. In addition, they individually received information about the procedure that the researcher and an assistant provided on one-to-one basis for about 20 minutes, in which brochures containing the information were used. While, the control group was provided only general education as mentioned above. For data analysis, this study conducted ${\chi}^2$-test, Fisher's exact test and Mann-Whitney U-test. The pre-operation provision of information was found having brought significant differences between the control and experimental groups in their anxiety(U=104.5, p=.015) and uncertainty(U=83.5, p=.002) as well as their satisfaction after the operation(U=109.5, p=.022). The findings of this study strongly suggest that information provision before the operation is positively effective in reducing the anxiety and uncertainty of mothers with a tonsillectomy child and increasing their nursing satisfaction after the operation. These effects need to be more verified through repetitive and subsequent researches and by using many other methods of information provision.

This study was conducted to develop a simulation-based education program for respiratory infectious disease and to identify the effects of clinical competency, self-leadership and critical thinking after applying to nursing students. A non-equivalent pre-post test of quasi-experimental design was used. The study subjects were 30 students for the experimental group and 30 for the control group. Respiratory infectious disease simulation-based education was provided for 5 weeks. Data analysis was performed using SPSS WIN Ver 21.0 with Fisher's exact test, independent t-test, and paired t-test. Clinical competency, self-leadership, and critical thinking of the experimental group showed statistically significant differences in comparison with the control group. These study results proved that a simulation-based education program for respiratory infectious disease is effective in raising nursing students' clinical competency, self-leadership and critical thinking. Therefore, it is considered that simulation-based education should be provided to cultivate nursing problem-solving clinical competency, self-leadership or critical thinking by developing a scenario based on various clinical situations.
