Objectives : The purpose of this study is to review the effectiveness of fire needling treatment for knee osteoarthritis in comparison with manual acupuncture treatment. Methods : Through four foreign online databases (PubMed, Cochrane library, EMBASE, and CNKI) and five domestic online databases (NDSL, RISS, KISS, OASIS, and KTKP), we searched for clinical studies that performed fire needling treatment for knee osteoarthritis until May 10, 2019. Only randomized controlled trials were selected and we assessed the risk of bias according to the Cochrane RoB criteria. This review examined the selected studies into first author, publication year, sample size, outcome measurements, results, acupoints, treatment time & period and so on. Results : A total of 7 RCTs were selected in this review and all were conducted in China. Treatment period of more than 4 weeks and treatment visits of 10 to 20 times were the most common. EX-LE4 and ST35 (=EX-LE5) acupoints were most frequently selected in treatment. Among the evaluation indexes, a total efficacy rate was used the most. Most of fire needling groups showed more significant results compared with the manual acupuncture groups statistically. Conclusions : All studies showed that fire needling treatments for knee osteoarthritis were more effective than manual acupuncture treatments statistically. Therefore, the results of this study could be utilized as a preliminary data for another clinical research on fire needling treatment for knee osteoarthritis. However, further well-designed randomized controlled trials will be needed to develop sufficient evidence about the effectiveness and safety of fire needling treatment for knee osteoarthritis in the future.

Purpose - This study aims to verify the direct causal relationship between cost competitiveness and global network competitiveness, which are the tangible service quality factors determined by the shipping company, which in turn affect the shipper's customer satisfaction. Additionally, we empirically investigate the intangible, related service qualities determined by shipping companies, such as operational competitiveness and customer relationship quality, and how these then positively affect customer satisfaction through the formation of trust. Therefore, we examine the mediating effect of trust formation among different contractors for shipping services. Design/methodology - In order to examine the shipping company's tangible and intangible service-qualities perceived by the shipper on customer satisfaction and the process of trust formation between contractors, we collected valid data from 114 respondents out of 200 distributed questionnaires. The respondents consisted of domestic freight forwarders who engage with domestic and international shipping and logistics agencies. Descriptive statistics, confirmatory factor analysis, reliability, convergent and discriminant validities, common method bias, and PLS-SEM (partial least square-structural equation model) were analyzed using the program STATA 16. Findings - The findings of this study are as follows. First, our results showed that all hypotheses assumed in this study had statistically significant supporting evidence. Second, it was found that the mediating effect of trust was significant in affecting the quality of intangible service- qualities for customer satisfaction. Third, through supplementary analysis, we found that the global network competitiveness of domestic shipping companies will increase in importance in the future. In conclusion, the theoretical and practical implications of these findings are presented. Originality/value - This study reaffirmed the traditional causal relationship between customer satisfaction and tangible service quality. Additionally, we also contribute to the literature on the understanding of the causal relationship between trust formation and customer satisfaction through intangible interactions from a long-term perspective.

Objectives : Pityriasis rosea is an acute and subacute papular scaly disease, and is a disease that mainly resolves spontaneously. However, since the outbreak of COVID-19, the possibility that the disease may occur as a sequelae of the disease and side effects of vaccination has been announced. Methods : We searched articles related to oriental treatment of pityriasis rosea at organized in domestic and foreign DBs. Articles were searched for RCT. The results were summarized in tables and graphs, and meta-analysis was performed. Also, we assessed the risk or bias. Results : As a result of setting the herbal medicine alone treatment as an intervention for pityriasis rosea and Western medicine alone as the control group, total 9 articles were searched. We analyzed them and got the results. The efficient rate of the treatment group was statistically significantly higher than that of the control group. In addition, adverse events were significantly less in the treatment group than in the control group. Conclusions : Herbal medicine treatment can be more effective than Western therapy(mainly anti-histamines and glycyrrhizin injection) for pityriasis rosea. In addition, herbal medicine treatment can be superior to Western treatment for safety. However, the limitations of this study include the small number of articles, no other evaluation indicators other than the efficient rate, and insufficient data such as pathological examination.

공간보간기법은 미계측지역의 강수예측을 위해 통상적으로 사용되는 방법 중의 하나이다. 이 연구에서는 기상청에서 제공하고 있는 RCP 8.5 시나리오에 의한 남한상세 강수자료 중 지형이 복잡한 도서지역에서 제공되지 않는 데이터 누락격자에 대하여 최적의 공간보간기법을 선정하여 강수자료를 생성할 수 있도록 하였다. 적합한 보간기법을 선정하기 위해 데이터 누락지역에 대한 분석을 수행하였고, 최신 행정구역도에 맞추어 $1km{\times}1km$ 격자를 한반도 전체지역에 맞추어 생성된 격자를 사용하였다. ESRI사의 ArcGIS 프로그램을 이용하여 공간보간기법을 적용하였다. 사용된 보간법은 역거리가중치법(IDW), 정규크리깅(Ordinary Kriging), 보편크리깅(Universal Kriging), 스플라인(Spline)이며 가장 적합한 공간보간기법을 선정하기 위해 기후변화시나리오에 의한 데이터 중 해안선 주변 특정격자에서의 값을 누락시켜 공간보간기법을 통해 생성된 값과 기후변화 시나리오에 의한 값을 정량적으로 비교하였다. 공간보간기법의 적합도 평가를 위해 MAE(Mean Absolute Error), MSE(Mean Squared Error), PBIAS(Percent of BIAS), G(goodness of prediction) 분석을 수행하였고, 산점도 분석을 통해 실제값과 보간값의 오차율 평가를 병행하여 최적 공간보간기법을 결정하였다. 사용된 강수데이터는 RCP 8.5 시나리오에서 2015~2019년 중 강수가 높게 나타난 8월 자료를 이용하였다. 해안선 지역의 강수량 추정시 역거리 가중치법과 크리깅방법은 일부 지점에서 과다 추정되는 경향이 있고, 스플라인 방법이 전체적인 총 강수량이 기후변화시나리오에 의한 실제값과 유사한 것으로 나타났다. 실제값과 보간값의 교차검증을 수행한 결과 정규크리깅 기법이 가장 높은 정확도를 보였으며, 전체적으로 실제값과 유사한 범위내의 강수량이 생성되는 것으로 나타났다.

Objectives: The purpose of this study was to provide clinical evidence to support the use of herbal medicine combined with western medicine for BPSD. Methods: Studies were identified by searching CNKI, Pubmed, EMBASE, Cochrane Library, SCIENCEON, RISS, KMbase, KISS, OASIS. Literature searches of Chinese, English, and Korean databases were performed. Two authors independently extracted the data and evaluated the quality of each study. Results: The literature search identified 203 articles. Of these, 7 were selected for the analysis. The risk of bias in most studies was unclear. The most frequently used diagnostic tools were the NINCDS-ADRDA and DSM-IV. The most commonly used results indicator was NPI. In 6 of the 7 papers, combination treatment (herbal & Western medicine) was statistically significantly more effective than single treatment (Western medicine alone) for BPSD. No significant adverse events were reported. Conclusions: Herbal medicine in combination with Western medicine is more effective for treating BPSD than Western medicine alone. However, the quality of the studies used in this study was uncertain and the sample size was too small. Based on the findings of this study, more high-quality clinical trials are needed to confirm the efficacy of combination treatment.

Objective For patients with acute myocardial infarction (AMI), symptoms assessed by emergency medical services (EMS) providers have a critical role in prehospital treatment decisions. The purpose of this study was to evaluate the diagnostic accuracy of EMS provider-assessed cardiac symptoms of AMI. Methods Patients transported by EMS to 4 study hospitals from 2008 to 2012 were included. Using EMS and administrative emergency department databases, patients were stratified according to the presence of EMS-assessed cardiac symptoms and emergency department diagnosis of AMI. Cardiac symptoms were defined as chest pain, dyspnea, palpitations, and syncope. Disproportionate stratified sampling was used, and medical records of sampled patients were reviewed to identify an actual diagnosis of AMI. Using inverse probability weighting, verification bias-corrected diagnostic performance was estimated. Results Overall, 92,353 patients were enrolled in the study. Of these, 13,971 (15.1%) complained of cardiac symptoms to EMS providers. A total of 775 patients were sampled for hospital record review. The sensitivity, specificity, positive predictive value, and negative predictive value of EMS provider-assessed cardiac symptoms for the final diagnosis of AMI was 73.3% (95% confidence interval [CI], 70.8 to 75.7), 85.3% (95% CI, 85.3 to 85.4), 3.9% (95% CI, 3.6 to 4.2), and 99.7% (95% CI, 99.7 to 99.8), respectively. Conclusion We found that EMS provider-assessed cardiac symptoms had moderate sensitivity and high specificity for diagnosis of AMI. EMS policymakers can use these data to evaluate the pertinence of specific prehospital treatment of AMI.

Objectives To assess the effectiveness of chuna manual therapy for patients with total knee arthroplasty. Methods We searched 9 electronic databases(KISS, NDSL, RISS, OASIS, KMBASE, Cochrane Library, PubMed, CNKI, Wangfang data) using the keywords 'total knee arthroplasty OR total knee replacement' and 'tuina OR chuna' to identify RCTs that investigated the effectiveness of Chuna manual therapy after total knee arthroplasty. Results 23 RCTs were selected based on inclusion criteria. The systematic review showed positive effect of using chuna manual therapy after total knee arthroplasty. Conclusions 23 studies reported that chuna manual therapy had significant effects on total knee arthroplasty. However, many studies were exposed to probable high risk of bias. Also, all of the studies were published in one overseas country. Therefore, further research is required using well-designed RCTs to support the effectiveness of chuna manual therapy.

Purpose: This systematic review aims to identify factors associated with risk-reducing salpingo-oophorectomy (RRSO), including the uptake rate and decision timing, among women at high risk for hereditary breast and ovarian cancer (HBOC). Methods: We found 4,935 relevant studies using MEDLINE, Embase, CINAHL, and PsycINFO on July 6, 2020. Two authors screened the articles and extracted data. Twenty-four studies met the inclusion criteria. Quality assessment of articles was conducted using the Risk of Bias for Nonrandomized Studies tool. Results: Five types of factors were identified (demographic factors, clinical factors, family history of cancer, psychological factors, and objective cancer risk). The specific significant factors were older age, having child(ren), being a BRCA1/2 carrier, mastectomy history, perceived risk for ovarian cancer, and perceived advantages of RRSO, whereas objective cancer risk was not significant. The uptake rate of RRSO was 23.4% to 87.2% (mean, 45.2%) among high-risk women for HBOC. The mean time to decide whether to undergo RRSO after BRCA testing was 4 to 34 months. Conclusion: RRSO decisions are affected by demographic, clinical, and psychological factors, rather than objective cancer risk. Nonetheless, women seeking RRSO should be offered information about objective cancer risk. Even though decision-making for RRSO is a complex and multifaceted process, the psychosocial factors that may influence decisions have not been comprehensively examined, including family attitudes toward RRSO, cultural norms, social values, and health care providers' attitudes.

Purpose: Hysteroscopy can be used both to diagnose and to treat intrauterine pathologies. It is well known that hysteroscopy helps to improve reproductive outcomes by treating intrauterine pathologies. However, it is uncertain whether hysteroscopy is helpful in the absence of intrauterine pathologies. This study aimed to confirm whether hysteroscopy improves the reproductive outcomes of infertile women without intrauterine pathologies. Methods: We conducted a systematic review of 11 studies retrieved from Ovid-MEDLINE, Ovid-Embase, and the Cochrane Library. Two independent investigators extracted the data and used risk-of-bias tools (RoB 2.0 and ROBINS-I) to assess their quality. Results: Diagnostic hysteroscopy prior to in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was associated with a higher clinical pregnancy rate (CPR) and live birth rate (LBR) than non-hysteroscopy in patients with recurrent implantation failure (RIF) (odds ratio, 1.79 and 1.46; 95% confidence interval, 1.40-2.30 and 1.08-1.97 for CPR and LBR, respectively) while hysteroscopy prior to first IVF was ineffective. The overall meta-analysis of LBR showed statistically significant findings for RIF, but a subgroup analysis showed effects only in prospective cohorts (odds ratio, 1.40 and 1.47; 95% confidence interval, 0.62-3.16 and 1.04-2.07 for randomized controlled trials and prospective cohorts, respectively). Therefore, the LBR should be interpreted carefully and further research is needed. Conclusion: Although further research is warranted, hysteroscopy may be considered as a diagnostic and treatment option for infertile women who have experienced RIF regardless of intrauterine pathologies. This finding enables nurses to educate and support infertile women with RIF prior to IVF/ICSI.

This study investigated the prediction skill of the Asian dust seasonal forecasting model (GloSea5-ADAM) on the Asian dust and meteorological variables related to the dust generation for the period of 1991~2016. Additionally, we evaluated the prediction skill of those variables depending on the combination of the initial dates in the sub-seasonal scale for the dust source region affecting South Korea. The Asian dust and meteorological variables (10 m wind speed, 1.5 m relative humidity, and 1.5 m air temperature) from GloSea5-ADAM were compared to that from Synoptic observation and European Centre for medium range weather forecasts reanalysis v5, respectively, based on Mean Bias Error (MBE), Root Mean Square Error (RMSE), and Anomaly Correlation Coefficient (ACC) as evaluation criteria. In general, the Asian dust and meteorological variables in the source region showed high ACC in the prediction scale within one month. For all variables, the use of the initial dates closest to the prediction month led to the best performances based on MBE, RMSE, and ACC, and the performances could be improved by adjusting the number of ensembles considering the combination of the initial date. ACC was as high as 0.4 in Spring when using the closest two initial dates. In particular, the GloSea5-ADAM shows the best performance of Asian dust generation with an ACC of 0.60 in the occurrence frequency of Asian dust in March when using the closest initial dates for initial conditions.
