  • The Self-Adaptive Vision Correction Algorithm (SAVCA) developed in this study was suggested for improving usability by modifying four parameters (Modulation Transfer Function Rate, Astigmatic Rate, Astigmatic Factor and Compression Factor) except for Division Rate 1 and Division Rate 2 among six parameters in Vision Correction Algorithm (VCA). For verification, SAVCA was applied to two-dimensional mathematical benchmark functions (Six hump camel back / Easton and fenton) and 30-dimensional mathematical benchmark functions (Schwefel / Hyper sphere). It showed superior performance to other algorithms (Harmony Search, Water Cycle Algorithm, VCA, Genetic Algorithms with Floating-point representation, Shuffled Complex Evolution algorithm and Modified Shuffled Complex Evolution). Finally, SAVCA showed the best results in the engineering problem (speed reducer design). SAVCA, which has not been subjected to complicated parameter adjustment procedures, will be applicable in various fields.

  • Purpose: This systematic review was planned and performed in order to determine the clinical effectiveness of acupuncture for non-alcoholic fatty liver disease (NAFLD). Methods: We searched related randomized controlled trials in several medical online databases, including China National Knowledge Infrastructure (CNKI), Excerpta Medica dataBASE (EMBASE), Public/Publisher MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), National Digital Science Library (NDSL), and Research Information Sharing Service (RISS). NAFLD related outcomes were extracted from the included trials and meta-analyzed. Results: From the 8 included trials, the values of the following examinations were extracted: liver ultrasonography, liver CT, body fat CT, aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyltransferase (GGT), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, fasting blood sugar (FBS), hosmeostatic model assessment for insulin resistance (HOMA-IR), weight, body mass index (BMI), waist hip ratio (WHR), obesity degree, body fat mass, body fat rate, leptin, malondialdehyde (MDA), and super oxide dismutase (SOD). In the 4 outcomes, cure rate in liver ultrasonography (RR=1.56; 95%CI=1.05~2.31; P=0.03), cure rate in liver CT (RR=2.23; 95%CI=1.33~3.72; P=0.002), TC (MD=-0.78; 95%CI=-1.41~-0.15; P=0.02), and TG (MD=-2.05; 95%CI=-3.88~-0.21; P=0.03), acupuncture was more effective than the control intervention. Conclusions: In this meta-analysis, acupuncture relieved hepatic steatosis, and reduced TC, and TG in NAFLD patients. more well-planned studies are still needed due to the heterogeneity and the considerable methodological flaws in the analyzed trials.

  • This research empirically investigated halo effect in evaluating culture and art performance program. We diagnosed halo effect by using correlation analysis, factor analysis, and regression model on results and scores of fifteen evaluation indicators within three categories for the 107 Local Representative Performance Art Festivals in 2014 and 2015. The results indicates strong possibility of halo effect in culture and art performance evaluation. The correlation coefficients between evaluation indicators is higher than 0.5 and factor structure does not match with evaluation categories in both years. Scores in categories and standard deviations also are also significantly correlated with each other. The results implies that more sophisticated standard, diversification of evaluator, education, and meta-anlysis are need to control halo effect.

  • Objectives: Interest in the use of complementary and alternative treatments to treat dementia. Meditation is used to treat various symptoms of physical and psychological diseases. Some studies suggest that meditation might have positive effects on cognitive functions, especially attention, in the elderly. However, how meditation affects Alzheimer's disease (AD) patients remains unclear. In this review, we assessed the effectiveness of practicing meditation in combination with standard care in AD. Methods: We searched the CCRCT, MEDLINE, EMBASE, AMED and CINAHL databases on 30 May 2017. We included randomized controlled trials (RCTs) that used meditation in adult patients diagnosed with AD. We allocated patients to a meditation combined with standard care or a standard care-only group. Results: The two RCTs met the inclusion criteria. A total of 98 patients were included in the meditation with standard care and standard care-only groups in this review. All meditation programs in the included trials were based on practicing mindfulness. The results of our meta-analysis indicatedthat adjunctive mindfulness meditation programs exerted favourable but non-significant effects on cognitive function on the Mini Mental State Examination (MMSE) (MD=4.68, 95% CI -0.11 to 9.46; Z=1.92, p=0.06). Only one study assessed depression, anxiety, quality of life and stress. No adverse events related to meditation were reported in the included studies. Conclusions: Insufficient data iscurrently available to determine the effectiveness of practicing meditation on patients diagnosed with AD. Hence, further RCTs with high methodological quality and larger sample sizes are needed to effectively estimate the effects of meditation on AD.

  • This review investigated the effectiveness and safety of acupotomy treatment for scoliosis. There were 7 online databases used in the search from inception to March 17, 2021, for randomized controlled trials of the use of acupotomy in patients with scoliosis. The Cochrane risk-of-bias tool was used to assess the methodological quality of the studies included (n = 12). A quantitative synthesis of the randomized controlled trials was performed using RevMan Version 5.3. The effect sizes of studies were presented as mean differences for continuous outcomes and risk ratios for dichotomous outcomes, with a 95% confidence interval. As part of combined therapy, acupotomy was reported to significantly improve Cobb's angle compared with other treatments. Likewise, the Visual Analog Scale score, the Oswestry Disability Index score, and pulmonary function were also reported to be improved following acupotomy combination therapy. Although 5 studies mentioned the criteria for reporting adverse events, only 1 study reported adverse events. In conclusion, acupotomy may be an effective treatment for scoliosis. However, the small number, and heterogeneity of the included studies, as well as the poor methodological quality, indicate that higher-quality studies should be conducted to verify the effectiveness and safety of acupotomy treatment for scoliosis.

  • Low-level laser therapy including laser acupuncture (LLLT/LA) has been widely used for non-specific chronic low back pain (NCLBP). However, there is no critically appraised evidence of its potential benefits. This study aimed to evaluate the effectiveness of LLLT/LA for NCLBP. There were 12 databases (MEDLINE, CENTRAL, EMBASE, KoreaMed, KMBASE, KISS, NDSL, KISTI, OASIS, CNKI, CiNII, J-stage) searched for randomized controlled trials using LLLT/LA for NCLBP up until June 2019. The primary outcome was pain intensity and functional status/disability due to NCLBP. A random-effects meta-analysis was conducted on 20 studies involving 1,323 participants. LLLT/LA showed a significant positive effect on pain relief scores compared with sham treatments (SMD -0.51, 95% CI: -0.88 to -0.13; χ2 = 31.12, I2 = 74%). Alone, the therapy showed a significant positive effect on function/disability scores (30 participants, MD -11.90, 95% CI: -17.37 to -6.43). As an add-on treatment, it showed a significant positive effect on pain relief (80 participants, MD -5.10, 95% CI: -9.31 to -0.88; χ2 = 28.99, I2 = 97%) and improved function/disability scores (120 participants, MD 5.44, 95% CI: 2.19 to 8.68; χ2 = 4.07, I2 = 75%). Among 20 studies, 9 studies reported no adverse events and 1 study reported mild adverse events. LLLT/LA may be an alternative or add-on treatment for NCLBP.

  • Objectives The objective of this study was to evaluate the effect of chuna manual therapy for rhinitis. Methods We performed a literature search using ten electronic databases (PubMed, Embase, Cochrane Library, Chinese Academic Journals(CAJ), Research Information Sharing Service(RISS), Dbpia, National Digital Science Library(NDSL), Koreanstudies Information Service System(KISS), Korean Medical database(KMbase), and Oriental Medicine Advanced Searching Integrated System(OASIS)) and two academic journals up to the end of April 2021. We included randomized controlled trials (RCTs) which appraised the effect of chuna manual therapy (CMT) in the treatment of rhinitis. The risk of bias was evaluated from the Cochrane Risk of Bias tool. Results 4 appropriate RCTs were included and analyzed. The efficacy rate of the CMT group was statistically higher compared to the control group treated with medicine[RR 1.14 (95%CI 1.06 1.22), P<0.01]. Conclusions Based on results, CMT could be effective in rhinitis. However, evidence were limited due to small number of studies, lack of well-designed RCT and regional bias. Further well-designed research should be required to obtain stronger evidence.

  • 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.

  • Objectives: The purpose of this study is to assess the efficacy of Jibaekjihwang-hwan and Daeboeum-hwan combination therapy for the treatment of precocious puberty. Methods: 6 databases were searched from the date of inception until April 2021 for relevant studies. We included randomized controlled trials (RCTs) and non-randomized controlled trials (nRCTs) which focused on effects of Jibaekjihwang-hwan and Daeboeum-hwan on precocious puberty. Results: Total 8 literatures were included in qualitative analysis and meta analysis on results was conducted on 4 synthesizable studies. The response rate was significantly higher in Jibaekjihwang-hwan and Daeboeum-hwan combination group than in conventional therapy group. Also, serum estradiol and follicle stimulating hormone (FSH) level were significantly lower in Jibaekjihwang-hwan and Daeboeum-hwan combination group than in conventional therapy group. Conclusions: It seems that combination therapy of Jibaekjihwang-hwan and Daeboeum-hwan can effectively reduce serum estradiol and FSH level while increasing response rate significantly. Further high quality studies are needed to supplement the efficacy and safety of combination therapy of Jibaekjihwang-hwan and Daeboeum-hwan on precocious puberty.
