Purpose: The purpose of this study was to examine the effectiveness of Action Research (AR) approach in nursing. Methods: Participants were 64 perioperative nurses recruited from C hospital in Gwangju, Korea. The nurses were engaged in the project through 2 cycles of planning, acting, observing, and reflecting. A mixed-methods design was used to examine changes in participants and their knowledge management practice. Quantitative data were analyzed using SPSS 20.0 program and qualitative reflection data underwent content analysis. Results: During the project, participants developed standardized pre-operative checklists and opened an Internet Cafe to better manage their perioperative nursing information. At the end of the project, there was a significant increase in nurses' knowledge management (p=.015) and the rate of surgical material prescription errors decreased from 8.0% to 2.9%. Core AR project team members' teamwork skills and organizational commitment increased significantly (p=.040, p=.301, respectively). The main themes that emerged from the qualitative data were learning how to solve problems in practice, facilitating team activities through motivation, barriers of large participation, and rewarded efforts and inflated expectations. Conclusion: The AR project contributed to empowering participants to solve local problems. AR is a useful methodology to promote changes in practices and research participants.

Postoperative pain is one of the most frequently occurred pain in hospitals, but it has been underestimated because it is only a part of postoperative physiological Process and may disappear in time. It is necessary that nurses me the relaxation technique, planning and implementing by themselves independently, to reduce this postoperative pain. This study is aimed at showing the effect of relaxation technique on reduction of postoperative pain, and exploring the factors influencing postoperative. pain Fifty-seven patients with abdominal surgery who admitted in attacked D Medical Center to K University in Daegu have been studied. Of them twenty-nine were experimental group and the remaining twenty-eight were control group. This study has been conducted for collecting data through interviews and observation from August 23 to October 24, 1984. The tools of this study were two kinds: Postoperative Pain Scale is obtained from a review of references by the researcher, and relaxation technique, designed to use postoperative setting adequately, is also obtained from a review of references by the researcher. After confiriming no significant differences between the two groups, the hypotheses were statistically verified by x²-test, t-test, and pearson Correlation Coefficient. The results of this study are summerized as follows; ＊ The nam hypothesis that the experimental group who use relaxation technique will have less degree of postoperative pain than the control group who don't use relaxation technique is devided into three sub-hypotheses. 1. The first sub-hypothesis that the experimental group will have less score of postoperative pain than control group was accepted (t=7.810, p <.01). Even with controlling pain threshold, showing difference in some degree between the two groups, the experimental group has less score of postoperative pain than the control group. Therefore this confirms the acceptance of the first sub-hypothesis more strongly. 2. The second sub-hypothesis that the expermental group will have less frequency of analgesics than the control group is accepted (x²=9.85, p <.01). 3. The third sub-hypothesis that the experimental group will have less variation of pulse, respiration, and blood pressure between pre End post operative periods than the control group is rejected. So this hypothesis is reverified through comparing the variation of pulse, respiration, and blood pressure between pre and post changing Position to measure the pure effect of relaxation technique. pulse and respiration is significantly lowered in the experimental group (t=7.209, p<.01, t=3.473, p<.01), but systolic and diastolic blood pressure is not different significantly between the two groups (t= 1.309, p＞.05, t=1. 727 p>.05). Therefore the third sub-hypothesis is partially accepted. Conclusively, the researcher thinks that it is necessary that nurses should provide patients with relaxation technique to reduce postoperative pain, and to increase independence of nursing.

Purpose : To reveal clinical usefulness of functional MRI (fMRI) using sensorymotor and language stimuli for demonstrating anatomic relationship between sensorimotor or language cortices and lesions in the planning of brain tumor surgery. Materials and Methods : This study included 12 right-handed patients with brain tumors in or around sensorimotor or language cortices. Eleven patients were evaluated with primary motor and sensory stimuli. Of these patients, six patients were also evaluated with language stimuli. One patient was evaluated with language stimuli only. For fMR imaging, a 1.5T scanner was used and the EPI BOLD technique was employed. For postprocessing image, the SPM99 program and a program made by our department was utilized. We evaluated whether sensorimotor and language stimuli activate sensorimotor and language cortices. And also, clinical efficacy of revealing anatomic relationship between cerebral cortices and lesions for planning neurosurgical operation were evaluated. Finally, we compared post-operative neurologic function with pre-operative neurologic function in same patients. Results : The fMRI examination was successful in identifying the functional cortices and depicting anatomic relationship between functional cortices and lesions in all patients. In nine patients of 11 patients with identified sensorimotor cortices, postoperative grade of manual motor test was not changed, compared with preoperative grade. Whereas postoperative improved than preoperative grade in one patient of remaining two patients, postoperative aggravated than preoperative grade in the other. This result was due to atherosclerotic lacunar infarction, regardless of tumor resection. Postoperative deficit of language function was not found in seven patients with identified language cortices. Conclusion : fMRI could be a helpful method for determining the best approach to neurosurgical treatment in patients with brain tumors in or around sensorimotor or language cortices.

Purpose: This study aims to examine the effects of nursing interventions based on the Extended Theory of Planned Behavior (ETPB) regarding self-efficacy for exercise (SEE), physical activity (PA), physical function (PF), and quality of life (QOL) in patients with lung cancer who have undergone pulmonary resection. Methods: This quasi-experimental study was conducted between July 2015 and June 2018 in two university-affiliated hospitals. The intervention included pre-operative patient education, goal setting (action and coping planning), and feedback (behavior intention and perceived behavioral control). The intervention group (IG) (n=51) received nursing interventions from the day before surgery to 12 months after lung resection, while the comparison group (CG) (n=36) received usual care. SEE, PA, PF (dyspnea, functional status, and 6-minute walking distance [6MWD]), and QOL were measured before surgery and at one, three, six, and 12 months after surgery. Data were analyzed using the χ² test, Fisher's exact test, Mann-Whitney U test, t-test, and generalized estimation equations (GEE). Results: There were significant differences between the two groups regarding SEE (χ²=13.53, p=.009), PA (χ²=9.51, p=.049), functional status (χ²=10.55, p=.032), and 6MWD (χ²=15.62, p=.004). Although there were no time or group effects, the QOL mental component (Z=-2.78, p=.005) of the IG was higher than that of the CG one month after surgery. Interventions did not affect dyspnea or the QOL physical component. Conclusion: The intervention of this study was effective in improving SEE, PA, functional status, and 6MWD of lung cancer patients after lung resection. Further extended investigations that utilize ETPB are warranted to confirm these results.
