  • The purpose of this study was to find the effect of intuitive free association and systematic free association on the creativity of high school students group in the conceptual design process. Based on this study result, the conclusion can be summarized as follows. 1. There was meaningful relation between intuitive free association and creativity factor of high school students. Mean value of experimental group A 's creativity and it's factor originality, practicality, elaboration, and fluency which treated intuitive free association was increased. 2. There was meaningful relation between systematic free association and creativity factor of high school students. Mean value of experimental group B 's creativity and it's sub factors: originality, problem solving, elaboration, and fluency which was treated systematic free association was increased. 3. It was found that two different divergent thinking does not show any meaningful difference in creativities of two groups. However, the meaningful difference was found in post creativity test in each groups sub-factors. There was meaningful difference in practicality factor, though there was no meaningful difference in originality, elaboration, fluency factors. Using the obtained results, it was concluded that intuitive thinking and systematic thinking play different roles in practicality which is one of sub-factors of the creativity of high school students. Consequently, it can be concluded that systematic thinking which leads students to take a step to solve a given problem can elicit more scientific thinking, and helps students create more practical solution in problem solving than intuitive thinking that emphasize the quantitative aspect of ideas.

  • Objectives While sciatic neuropathy is one of the common symptoms which have the lifetime incidence of 13~40%, still there is no consensus about the standardized and the most effective conservative treatment. In addition, the importance of systematic review and meta-analysis of preclinical are growing as they could suggest possible effective treatment strategy for future studies. Therefore, we conducted systematic review and meta-analysis to estimate analgesic effect of acupuncture on sciatica in rat models. Methods Systematic search was conducted for all controlled comparative preclinical trials which assessed analgesic effect of acupuncture in sciatica rat models. Database of PubMed, EMBASE, Web of Science, CNKI and 6 Korean databases were used. The primary outcome was pain, which is evaluated by stimulus behavior tests in rat models. We assessed the methodological quality with Systematic Review Centre for Laboratory Animal Experimentation's risk of bias tool. RevMan 5.3 was used for meta-analysis and subgroup analysis was conducted according to treatment site, acupuncture point, treatment period and frequency used in electroacupuncture. Results 14 studies were finally included following our inclusion criteria. The data from meta-analysis indicated that the acupuncture significantly improved the result values of behavior tests for pain evaluation, compared to no-treatment control group in animal models (standardized mean difference=4.43, 95% confidence interval 3.16 to 5.69, Z=6.84, p<0.00001; χ2=68.02, p<0.00001; I2=82%). The results of subgroup analysis indicate that acupuncture treatment of unilateral site, distal acupoints, longer treatment period and applying 2/100 Hz frequency in electroacupuncture could be more effective. Conclusions Systematic review and meta-analysis of animal studies are getting important for the future clinical studies and the improvement of heatlh care. Therefore the results of the study would provide evidence and better design for the forthcoming studies.

  • This study analyzes determinants of bond returns in terms of systematic risk versus idiosyncratic risk by examining relationship among those factors. First we examined the cross-sectional determinants of corporate bond returns with Korean bond market data from 2001 to 2014. This paper uses term factor and default factor for systematic risk, and duration factor and credit rating factor for idiosyncratic risk. The empirical result shows that systematic risk can explain cross-sectional differences of bond returns rather than idiosyncratic risk which is the same result in advanced markets(US or Europe). This result is different from the previous Korean studies which showed that idiosyncratic risk is more important than systematic risk in Korean bond market. The reason for the different result may be the longer sample period which includes the most recent period. It is insisted that Korean bond market is getting more synchronized with the advanced bond market. In conclusion, this empirical result implies that Korean bond portfolio managers should focus on systematic risk, which is contrary to current system in Korean asset management industry.

  • Objectives : The publication of systematic reviews (SRs) has increased significantly over the years, and systematic reviews are considered to have the strongest evidence as they are at the top of the hierarchy of evidence pyramid. In this study, a thorough assessment of all SRs published in Journal of Society of Preventive Korean Medicine (JSPKM) was performed to evaluate their reporting quality and methodological quality to better improve the quality of SRs in JSPKM. Methods : JSPKM website was searched to include all SRs published in JSPKM from 1997 to 2018. Two independent researchers assessed the SRs using A MeaSurement Tool to Assess systematic Reviews (AMSTAR, formerly known as Assessment of Multiple Systematic Reviews) tool checklist for methodological quality assessment, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline checklist for reporting quality assessment. Results : Out of 618 published articles published in JSPKM from 1997 to 2018, only 3 SRs were identified as SRs. For AMSTAR methodological quality scoring, the average score of 3 SRs was 3.0 out of 11 which is low quality level. For PRISMA reporting quality items, the 3 SRs reported 17.3 items on average out of 27 items. The 3 identified SRs did not provide information on protocol or registration which is included in both AMSTAR assessment tool and PRISMA guideline. Conclusions : Improvements on reporting quality and methodological quality of SRs using relevant tools or guidelines are needed to assure the quality of SRs published in JSPKM so that their conclusions will be more transparent and reliable for decision-making in healthcare and the best clinical practice.

  • Purpose: The purpose of this study was to review nursing studies with regard to simulation- based learning in Korea. Methods: This systematic review examines the literature on simulation in nursing education from 2003 to 2012. The electronic databases reviewed included: RISS, the National Assembly Library, the National Library of Korea, and major nursing journal databases in Korea. The MeSH search terms included nursing, simulation, simulator, and standardized patient. Results: In total, 52 studies were included in the literature review. We included 21 quasi-experimental studies and 25 studies using high-fidelity simulation. They included knowledge and problem-solving ability in the cognitive domain; self efficacy, learning satisfaction, interpersonal relationships and communication, and confidence in the affective domain; and clinical performance ability and learning performance evaluation in the psychomotor domain. This systematic literature review revealed that simulation is useful in nursing education but uncovered a gap in the literature pertaining to the transfer of knowledge to performance and how to learn from cognitive reflection. Conclusions: This result suggests that it is necessary to conduct additional research on the cognitive learning process and transition to performance.

  • Purpose: This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed-based chemoradiotherapy in treating patients with locally advanced or metastatic esophageal cancer. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for relevant patients were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: For pemetrexed-based regimens, 4 clinical studies including 47 patients with locally advanced or metastatic esophageal cancer were considered eligible for inclusion. Systematic analysis showed that, in all patients, the pooled RR was 51% (24/47). Major adverse effects of grade III/IV were esophagitis, neutropenia, thrombocytopenia, anemia anorexia, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. Conclusion: This systematic analysis suggests that pemetrexed based radiotherapy is associated with reasonable activity and good tolerability in treating patients with locally advanced or metastatic esophageal cancer.

  • Purpose: This study is a systematic literature review and meta-analysis study conducted to identify the effects of breastfeeding intervention program on premature infants by integrating and analyzing the results of randomized controlled trials and non-randomized trials. Methods: The literature review process was based on the PRISMA (Preference Reporting Items for Systematic Reviews and Meta-Analyzes) guideline. Data retrieval and collection were conducted from May 25 to May 30, 2018, and the articles analyzed were all domestic papers retrieved from the database. Two reviewers independently select the studies and assessed methodological risk of bias of studies using the Cochrane criteria. The topics of breastfeeding interventions were analyzed using descriptive analysis and the effects of intervention were meta-analyzed using the R program. Results: Finally, eight papers were included in the systematic review and meta-analysis. The breastfeeding intervention program for premature infants showed a significant increase in the self-efficacy and the amount of pumping and baby's hight. Conclusion: This study has some limitations due to the few randomized controlled trials and non-randomized trials comparing breastfeeding for premature babies in Korea. Therefore, it needs to be integrated with the research conducted in other countries.

  • Purpose: This study was conducted to identify the factors influencing of HPV vaccination and vaccination intention among Korean adult women through a systematic review. Methods: A systematic review was conducted across international and domestic electronic databases and nine of 193 studies were identified for this review. Results: Meaningful variables influencing HPV vaccination and its intention included socioeconomic status (age, economic level, and education level), knowledge level, health beliefs, attitudes toward HPV vaccination, and previous experiences. Economic level and knowledge influenced HPV vaccination and vaccination intention, which was consistent with the results of previous studies. Eight studies measured knowledge level regarding cervical cancer or HPV vaccination; however some instruments lacked reliability and validity report. Conclusion: There is a need for governmental support to reduce the burden of HPV vaccination cost, to publicize the benefits and to provide general information regarding HPV vaccination. Finally, it is necessary to develop an instrument with confirmed reliability and validity to measure HPV knowledge.

  • Objective: This study was undertaken to systematically assess and summarize the effects of acupuncture on cortisol secretion. Materials and methods: We searched articles published up to May 2010 in six electronic databases (PubMed, Cochrane Library, KISS, KISTI, DBPIA, Kyobo Scholar). Randomized clinical trials (RCTs) which met all the inclusion criteria were reviewed. Eight RCTs were finally selected for this systematic review and assessed by three reviewers. The risk of bias was also estimated by using the Cochrane criteria. Results: Six RCTs reported no distinct difference of cortisol levels between control and experimental groups. Two RCTs reported significant differences of cortisol levels between groups; one reported the acupuncture group with markedly higher concentrations of cortisol while the other reported the opposite result. Conclusion: There are some difficulties in clearly identifying the effects of acupuncture on cortisol levels in this systematic review due to inconsistent results. Therefore, more rigorous trials with larger scales need to be conducted to clarify the effects of acupuncture on cortisol levels.
