  • This study investigated the antioxidant activities of distilled water, ethanol and methanol extracts of Plunus mume flower buds (PFB). The various solvent extracts of PFB were evaluated for their total polyphenol, flavonoid, reducing power and free radical scavenging activities by FRAP and DPPH analysis. The ethanol extract of PFB contained significantly higher amounts of total polyphenols (145 mg GAE/g) and flavonoids (25.43 mg QE/g) than methanol (132 and 25.42) and distilled water (113.6 and 18.04). Among solvent extracts of PFB, the ethanol extract showed the highest antioxidant activities. The 100% ethanol extract of PFB contained significantly higher amounts of total polyphenols and flavonoids than 70% and 50% ethanol extracts. Moreover, the 100% ethanol extract of PFB showed high efficacy in DPPH radical scavenging activity and in collagenase inhibition activity. This results suggest that 100% ethanol extract of PFB has the most effective antioxidant capacity compared to the methanol and water extracts tested in the present study. Thus, it can be applied for the effective extraction of functional material from PFB for usage of cosmeceutical and/or food industries.

  • Purpose: This study was to identify predictors of drug dosage calculation error risk in newly graduated nurses. Methods: A total of 115 newly graduated nurses who passed their employment examination, but didn't work for hospital yet, were recruited from a university hospital. The data were analyzed by descriptive statistics, $X^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression using the SPSS 18.0 program. Results: The mean score of 'drug dosage calculation ability' was $0.81{\pm}0.16$ and the mean score of 'certainty of calculation' was $2.95{\pm}0.60$ out of a 5 point scale. The error risk of drug dosage calculation was positively related to anxiety for drug dosage calculations (r=.388, p<.001), but negatively related to interest and confidence in mathematics (r=-.468, p<.001), confidence related to dosage calculations (r=-.426, p<.001). The main predictors of error risk related drug calculations in newly graduated nurses were identified as interest and confidence in mathematics (${\beta}$=-.468, p<.001). This factor explained about 21.9% of the variance in error risk of drug dosage calculation. Conclusion: The strategies used to decrease the error risk related drug dosage calculation such as improving interest and confidence in mathematics should be developed and implemented.

  • Objectives : This study was aimed to facilitate mutual comprehension between Western and Traditional Korean Medicine (TKM) by analyzing recognition of medical school students on traditional medical prescription and treatment such as herbal medicines and acupuncture. Methods : We conducted a survey targeting medical school students of four medical schools from April through May 2009, and analyzed 208 cases responded. Results : Survey results revealed that medical school students took knowledge of traditional medicine from TV programs and on the Web in general. They thought they had considerable traditional medical knowledge but did not almost understand for professional contents. Regardless of some positive recognition for traditional herbal medicine, negative perspectives were more common and its safety and efficacy on the drug reference were considered as a major reason. On the other hand, recognition on acupuncture was comparatively positive. Scientific data for both herbal medicine and acupuncture are lacking in reality but the attitude only for acupuncture was different. Of the survey respondents, 57.8% had negative attitude against diagnostic methods of TKM and 59.1% opposed to the usage of modern medical equipments by TKM doctors. With regard to the future position of TKM, they tacitly approved that TKM would be absorbed into the complementary and alternative medicine (CAM) and importance of TKM objectification, followed by Government's support. Conclusions : Medical school students neither affirm nor deny TKM as a whole but the state of awareness for each item was similar to the physician. In terms of TKM its internal and external innovation would be required to continuously establish objectification of TKM prescription and scientific research on treatment technology.

  • Background : In this paper patient outcomes research is going to be reviewed and described, to be compared with relevant studies, and to consider the application in Korea. Methods : We compiled and reviewed the articles and materials related to patient outcomes research especially by PORT(Patient Outcomes Research Team) and rearranged them for seeking the main point and comparing with relevant studies. Results : Patient outcomes research emphasizes patient outcomes as well as conventional clinical outcomes. It is prospective study observing effectiveness in real situation instead of efficacy in ideal condition. Patient outcomes research comprises of 6 fields ; literature review and meta-analysis, use of claims data, decision modeling, outcomes assessment, cost of care, dissemination of research findings. SAA(small-area variations analysis), appropriateness study and clinical practice guideline are connected with patient outcomes research. Conclusion : In view of the fact that current medical policy in Korea is shifting its focus from accessibility to the improvement in quality and cost containment, and is stressing patient-based research, patient outcomes research is one direction for which the medicine is accountable and assessable. Considering that the number of patient receiving medical treatment in Korea is higher than the West, patient outcomes research has competitive power as against the West.

  • Problem-Based Learning (PBL) is a student-centered pedagogy that integrates nursing knowledge, skills, and attitudes into clinical nursing practice. This pilot aims to apply a PBL module on preschoolers' growth and development in the nursing curriculum. This quantitative study was performed to develop a PBL module following Dick and Carye's program development process (planning, development, application, and evaluation phases), and to evaluate its effects using structured questionnaires among sophomore nursing students. These students formed teams of four or five people each and spent 40 minutes participating in the PBL module. Data were analyzed using descriptive statistics, t-tests, and content analysis. Metacognition level increased significantly. There was no significant difference in team efficacy between pre-test and post-test. Post-test learning satisfaction was high. Students reported obtaining knowledge and problem-solving ability with respect to preschoolers' growth and development and were satisfied with teamwork. This finding offers fundamental knowledge concerning the application of a PBL module in nursing curricula.
