  • Objectives: To evaluate the evidence supporting the effectiveness of Chuna manual therapy for rheumatoid arthritis. Methods: We conducted a search across 9 electronic databases to find all randomized controlled clinical trials (RCTs) that used Chuna manual therapy as a treatment for rheumatoid arthritis. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results: Our inclusion criteria were met by 5 RCTs. The meta-analysis showed positive results for the use of Chuna manual therapy combined with oriental usual care (UC) in terms of the efficacy rate, pain, and duration of morning stiffness when compared to western UC. Positive results were also obtained in terms of the efficacy rate, when Chuna manual therapy combined with medication was compared to medication treatments alone. Conclusions: Our systematic review found encouraging, but limited evidence of Chuna manual therapy for rheumatoid arthritis. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend a comparative research to test the effectiveness of Chuna manual therapy.

  • The Polarization and Depolarization Current (PDC) measurement is an efficient and effective diagnostic technique based on time domain measurement, for evaluating the high voltage insulation condition. This paper presents a review and comparison results from several published papers on the application of the PDC method to finding the conductivity and moisture content of various types of insulators. For solid insulation, the study was focused on cable insulation, electric machine stator insulation, and paper insulator in transformer insulation with different conditions. For liquid insulation, the review and comparison was done on biodegradable and mineral transformer oils, with fresh oil condition, and aged condition. The results from previous researchers tests were complied, analyzed and discussed, to evaluate the application of the PDC method to monitor the conductivity and moisture of HV equipment insulation systems. From the review results, the PDC technique successfully gives an indication of the conductivity and moisture level of high voltage insulation.

  • Objectives: The purpose of this systematic review is to overview and evaluate the effect on postpartum hypogalactia after acupuncture treatment. Methods: Relevant randomized controlled trials (RCTs) were identified by database searches in Embase, Pubmed, CENTRAL, CNKI, KISS. Searching keywords were "Hypogalactia" or "Hypolactaion" and "Acupuncture". After searching qualified articles, we independently assessed the risk of bias according to the Cochrane Rob criteria. Results: Among the 81 articles five RCTs were finally selected. Four of the selected were statistically significant. One of them was not statistically significant because it was comparative study of chinese medicine and acupuncture treatment. The quality of the evidence for specific comparisons ranged from low to high. Conclusions: Our systematic review found encouraging. Acupuncture treatment would be effective way to increase insufficient milk supply on postpartum hypogalactia.

  • Purpose: This study was conducted to compare cemented and cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures via meta-analysis and systematic review of relevant studies. Materials and Methods: Systematic review and meta-analysis were performed on 31 available clinical studies; 19 of these studies used cemented stems, 12 used cementless stems, one used both types of stems, and two studies involved a comparative analysis of both stem types. Results: There were statistically significant differences in rates of leg length discrepancy (LLD) greater than 1 cm between the cemented (event rate, 0.089) and cementless groups (event rate, 0.015 and 0.047; P=0.03). Conclusion: Cemented bipolar hemiarthroplasty and cementless bipolar hemiarthroplasty performed on elderly patients with unstable intertrochanteric fracture revealed similar mortality and complication rates; however, the rate of LLD greater than 1 cm was significantly higher in the cemented group compared with the cementless group.

  • The growth of pulsed electromagnetic field (PEMF) therapy and its progress over the years for use in post-operative bone growth has been revolutionary in its effect on bone tissue proliferation and vascular flow. However, further progress in PEMF therapy has been difficult due to lack of more evidence-based understanding of its mechanism of action. Our objective was to review the current understanding of bone growth physiology, the mechanism of PEMF therapy action along with its application in spinal surgery and associated outcomes. The authors of this review examined multiple controlled, comparative, and cohort studies to compare fusion rates of patients undergoing PEMF stimulation. Examining spinal fusion rates, a rounded comparison of post-fusion outcomes with and without bone stimulator was performed. Results showed that postoperative spinal surgery PEMF stimulation had higher rates of fusion than control groups. Though PEMF therapy was proven more effective, multiple factors contributed to difficulty in patient compliance for use. Extended timeframe of treatment and cost of treatment were the main obstacles to full compliance. This review showed that PEMF therapy presented an increased rate of recovery in patients, supporting the use of these devices as an effective post-surgical aid. Given the recent advances in the development of PEMF devices, affordability and access will be much easier suited to the patient population, allowing for more readily available treatment options.

  • CPU is considered the main and most important resource in the computer system. The CPU scheduling is defined as a procedure that determines which process will enter the CPU to be executed, and another process will be waiting for its turn to be performed. CPU management scheduling algorithms are the major service in the operating systems that fulfill the maximum utilization of the CPU. This article aims to review the studies on the CPU scheduling algorithms towards comparing which is the best algorithm. After we conducted a review of the Round Robin, Shortest Job First, First Come First Served, and Priority algorithms, we found that several researchers have suggested various ways to improve CPU optimization criteria through different algorithms to improve the waiting time, response time, and turnaround time but there is no algorithm is better in all criteria.

  • This study aims to review the environmental impact assessment systems of Japanese local governments, to compare its outcome with the systems of Korean local governments, and to suggest the development direction for the environmental impact assessment systems of Korean local governments based on the result. The study results showed that, first, due to distinction in the political systems of Japan and Korea, while Japan has bottom-up environmental impact assessment systems, Korea has topdown environment impact assessment systems. Second, although introduction of national systems on planning was put on hold as a future initiative, local governments including Tokyo and Saitama are experimenting evaluation procedures tailored to local features by legislating them as regulations. On the other hand, while 'prior environmental review system' was in effect as a national system, nothing was practiced at all by local governments. Third, in a total of 47 Japanese local governments, about 45 projects and 44 assessment items were added to local government environmental impact assessment only and designated as target projects and assessment items. Fourth, in both national and local environment impact assessment systems in Japan, screening procedures to determine assessment by separating into Type 1 projects and Type 2 projects and scoping procedures to discuss assessment items in advance were introduced and in effect. This Japanese EIA system may serve as a good reference to the Korean national and local government EIA systems.

  • Recently, ITSM(IT Service Management) is adopted very widely among private and public organizations. The successful implementation of ITSM requires continuous improvement, not just implementation of IT processes and/or ITSM solutions. One of the major tools for the continuous improvement is 6 Sigma technique. This study compares success and failure cases at the project level, and identifies factors affecting successful application of 6 Sigma technique in the improvement of ITSM. To achieve the research objective, this study first identifies and classifies success factors for 6 Sigma application through literature review. Then, factors to be used in the study are determined. Based on the factors, success and failure cases are compared. The research results show that all 5 factors (participation of management, participation of project team, project selection and verification, customer and market orientation, strategy and goal focus) are significantly different between success and failure cases.

  • This study examines internationalization index of higher education to draw implications for South Korea. To this end, this study first introduces the concept of internationalization of higher education, followed by the background of the development of internationalization index. Then examined are two internationalization index of higher education: one developed by American Council Education (ACE) and the other developed by OECD, which is known as IQRP (International Quality Review Process). ACE's international index of higher education is useful to governments when they assess the process of internationalization of universities. IQRP, on the other hand, is useful to universities and colleges when they evaluate their status of internationalization. Drawn implications are (1) it is important for universities to build a clear goal and implement appropriate strategies of internationalization, (2) policies on internationalization of higher education should concentrate on contents rather than forms, and (3) the efforts for internationalizing higher education should be made along with the efforts for improving the quality of education.

  • Objectives To obtain future research basis of Korean Medicine for total knee arthroplasty patient by analyzing medical and Korean Medical service utilization and treatment duration. Methods Data sampling was performed on Health Insurance Review and Assessment Service patient data of 2015 (Confidence level of 97%) to analyze patients' medical and Korean Medical service tendency. Sampling groups were divided into two groups; i) Patients who completed their treatment within 5 months of total knee arthroplasty, ii) Patients who continued their treatment after 5 months of total knee arthroplasty, to investigate patients' medical and Korean Medical service tendency and individual characteristics were carefully monitored. Results It was confirmed that total of 1,655 patients had gone through total knee arthroplasty out of 1,453,486 patients who were gathered for sampling. First sampling group (Patients who completed their treatment within 5 months of total knee arthroplasty) was 287 patients and second sampling group (Patients who continued their treatment after 5 months of total knee arthroplasty) was 385 patients. The proportion of patients who visited Korean Medical service in first sampling group was lower than that of second sampling group. Conclusions It was confirmed that medical and Korean Medical service and cost consumed by second group (Patients who continued their treatment after 5 months of total knee arthroplasty) was higher than that of first group (Patients who continued their treatment after 5 months of total knee arthroplasty). It is highly recommended to continue with further study for efficient medical and Korean Medical service and reduced cost.
