The aim of the study is to create a theoretical model and hypotheses on competitive advantages of exporting SMEs. For this we have proposed an integrated model in which learning competences and dynamic capabilities should have an influence on competitive advantages of the SMEs. This study have examined the influence of integrating and reconfigurating capability respectively. As a result, the learning competences had positive influences in dynamic capabilities and to the cost and service competitive advantage. To integrating capabilities had positive influences in competitive advantage. Besides, dynamic capabilities playing significant intermediate role only for the cost advantage through the analysis of intermediate effects of learning competence to the dynamic capabilities.

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.

Circulation data is a key data set of academic libraries in terms of collection development and service improvement This study aims to identify the characteristics of circulation measures and their feasibility. This study collected the circulation data of 10 colleges in a university and analyzed 4 measures based on the circulation data: circulation frequency, circulation entropy, circulation h-index, and circulation divergence. These measures are to present the circulation topics of each college. This study identified that circulation entropy tends to present general topics which are popular for many colleges, but circulation divergence tends to present specific topics which are preferred by a specific college.

Objectives This study aimed to review clinical studies about Korean medicine used in peroneal nerve palsy. Methods In 11 online databases (Earticle, Research Information Sharing Service, Oriental Medicine Advanced Searching Integrated System, KMbase, Korean Traditional Knowledge Portal, National Digital Science Library, MEDLINE/Pubmed, Ebscohost, Cochrane CENTRAL, EMBASE, China National Knowledge Infrastructure), we searched clinical studies about Korean medicine. Among the studies that we've searched, we excluded the studies that are not related to Korean medicine, case reports, randomized controlled trials and retrospective studies. As a result, 16 case studies and 1 randomized controlled trial are included. Results Total number of patients was 123. In these studies, acupuncture (100%), herbal medicine (58.8%), pharmacopuncture (58.8%), Korean physical therapy (58.8%), moxibustion (41.1%), cupping (41.1%) etc. were used. In acupuncture, GB34 and ST36 were most frequently used. Most of the herbal medicines used in these studies were different. Range of movement were most frequently used in outcome measure. Conclusions In this study, we reviewed studies about Korean medicine used in peroneal nerve palsy. It was difficult to clearly determine which intervention has improved the symptom. In the future, Further clinical studies will be needed to retain the evidence for the treatment of peroneal nerve palsy. And also more randomized controlled clinical trials to prove the efficacy of Korean medicine will be needed.

Objectives: The purpose of this study was to assess the effects of moxibustion treatment for Cardiac arrhythmia through a systematic review. Methods: Electronic database including Cochrane library, Pubmed, China National Knowledge Infrastructure, Embase, DBpia, and Korean studies Information Service System were searched by combining the keywords such as "arrhythmias", "cardiac arrhythmias", "心律失常", "moxibustion" and "艾灸". Through the searching, 5 randomized controlled trials(RCTs) were included except animal testing and cellular experiment etc. The quality of each RCTs was assessed using the Cochrane risk of bias tool. Results: We included 5RCTs involving 468 participants. Two RCTs compared moxibustion versus conventional treatment, another RCT compared moxibustion plus acupuncture versus conventional treatment, another RCT compared moxibustion plus herbal medicine verus conventional treatment, the other RCT compared moxibustion plus herbal medicine and ointment versus conventional treatment. These studies were evaluated by the efficacy rate of treatments. Studies measured outcomes in efficacy, heart rate, electrocardiogram and symptoms. Each of 5 trials statistically showed a significant differences in efficacy rate. One study reported about side effects and another study reported about complications. The overall risk of bias was unclear in 5 studies. Conclusions: The evidence suggests that moxibustion treatment may help to reduce cardiac arrhythmia, however, it is limited, low-certainty and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.

Objectives: This study was performed to review the research trends in the relationship between primary dysmenorrhea and doppler indicies of uterine artery. Methods: The search for related papers used 'Pubmed', a reserch engine in the America National Library of Medicine and Korean studies Information Service System (KISS). Used searching terms were 'primary dysmenorrhea', 'menstrual pain' in all cases. And among these studies, we searched by using key word 'uterine artery', 'doppler indices', 'doppler parameters', 'pulsatile index', 'resistance index'. Results: Overall 49 studies, 8 studies were finally selected to this study. There were 6 controlled studies and 2 randomised-controlled studies. In all 8 studies, transvaginal ultrasound was used to measure the resistance of uterine blood vessels. All of these studies reported that in patients with primary dysmenorrhea, hemodynamic values of uterine arteries measured by Doppler ultrasound were significantly higher than in normal subjects. Conclusions: According to the results, it was found that there was a positive correlation between the pain level of primary dysmenorrhea and the pulsation index and resistance index of the uterine artery. Based on these results, it can be seen that the doppler indicies of uterine artery have the potential to be used as an evaluation scale for Korean traditional medicine for primary dysmenorrhea.
