Purpose - This study investigates the relationship between firm-specific, general human capital and corporate innovation performance. Also, we examine when this relationship is more salient. Design/methodology/approach - We collected 1,195 survey data related to a sample of corporate innovation performance and human capital from 1) Korea Research for Vocational Education and Training and 2) NICE information service in Korea. In order to examine the corporate innovation performance, we use the ordered logit model. Findings - First, we find robust supports for our hypothesis that firm-specific and general human capital increase corporate innovation performance. Second, the effect of general human capital on corporate innovation performance is stronger when this relationship is combined with the firm international experience. Research implications or Originality - By integrating the human capital theory and corporate innovation literature, we propose that firm-specific and general human capital are the important determinant of innovation performance. The firm-specific human capital may increase innovation efficiencies. Also, retaining higher-quality general human capital is considered as an important innovation strategy since firms with higher-quality general human capital make greater innovation performance. Further, we show that the firm international experience is the crucial boundary condition. As a firm's experience in internationalization increases, firms can enhance the opportunities to develop new products by combining the skills and knowledge derived from general human capital with the experience gained through internationalization.

Objectives: This research aimed to investigate Chinese clinical studies on the treatment of central post-stroke pain (CPSP) and thalamic syndrome after stroke with traditional herbal medicine (THM). Methods: Randomized controlled trials verifying the effects of herbal medicine on treating CPSP and thalamic syndrome after stroke were included in the study. Electrical and hand search were conducted in the China National Knowledge Infrastructure (CNKI), National Discovery for Science Leaders (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (Oasis) for CPSP and thalamic syndrome after stroke. A literature search was performed in the Chinese and Korean databases for papers published from January 1, 2010 to October 1, 2018. The selected literature was assessed by Cochrane's risk of bias. Results: Twelve reports on randomized controlled trials met the inclusion criteria from the 227 identified reports. Effective rate, comparison of visual analogy scale, present pain intensity, pain grading index, recurrence rate, follow-up, and a 36-item short form survey instrument were used to evaluate the treatments. The effective rate of the treatment group was significantly higher than that of the control group in all papers. Side effects occurred less frequently in the treatment group than in the western medicine control group. Conclusions: The treatment of CPSP and thalamic syndrome after stroke with THM was shown to be highly effective. Additional well-designed clinical trials are needed. This study can be used as a basis for further research on the treatment of CPSP and thalamic syndrome after stroke.

Objectives: The aim of this review is to investigate clinical studies on Oriental medicine treatment for aphasia after cerebrovascular disease. Methods: Using the keywords 'Aphasia', 'Oriental medicine', 'Stroke' 'Cerebral infarction', 'Cerebral hemorrhage', and 'Clinic', we searched domestic databases, including "NDSL (National Discovery for Science Leaders)", "Korean Traditional Knowledge Portal", "OASIS (Oriental Medicine Advanced Searching Integrated System)", and "RISS (Research Information Sharing Service)". Each keyword was not searched individually, but combined in various ways. To investigate recent trends, we limited our search to papers published after 2000. Papers that did not include a specific treatment method or did not match the subject "Aphasia after stroke" were excluded. Results: Using the searching method, 13 studies were found. Of these, 12 studies were in the form of case reports, while one was in the form of a non-randomized controlled trial. These studies showed positive results for the use of Oriental medicine in terms of the Korean version of the Western Aphasia Battery (K-WAB), the evaluation form on functional performance capability and accuracy of articulatory organs developed by Lee, aphasia screening test refered in 'Assessment in Speech-Language Pathology' and adapted properly to Korean, the Communicative Ability in Daily Living Test (CADLT), the Korean Version-Boston Naming Test (K-BNT), and language assessment items included in CNS, and NIHSS. Conclusions: Of the 12 case reports, 11 studies showed positive results of the use of Oriental medicine for treatment of aphasia after cerebrovascular disease. However, more sophisticated and large-scale clinical research on aphasia should be conducted.

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.

A tree-length harvesting system using the HAM300, which is mounted on a farm tractor prototype machine, have been recently introduced in South Korea for thinning old (>30 years) forests. However, no research has previously been conducted on the characteristics of residual stand damage associated with cable yarding systems on thinning treatment stands in South Korea. Therefore, there were assessed on the degree and quantity of residual stand damage caused by felling and yarding process to broaden the knowledge of residual stand damage on semi-mechanized skyline thinning operations. This study investigated scar size, direction, area, shape type and their distribution on the residual stand damage caused by felling and yarding operations. Damage to residual trees was generated for 7.4% and 6.9% of residual trees in felling and yarding operations, respectively. Damaged direction of scars was located in front-side (38.9%) and up-side (34.7%) for felling operations while the highest scar damage was found on down-side (44.6%) for yarding operations. Scar heights of felling damage were higher than those of yarding damage. In yarding operation, the most of the scars was located within l0m from the center of the skyline corridor. These results should be useful information for forest managers and landowners to reduce residual stand damages and retain valuable timber volume from thinning treatments.

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: The purpose of this review is to overview the studies of traditional herbal medicine for chronic pelvic inflammatory disease. Methods: We searched relevant studies using seven databases (The Journal of Korean obstetrics & gynecology, National Digital Science Library (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Pubmed, Cochrane, Chinese National Knowledge Infrastructure (CNKI)). Data retrieval was carried out on April 5, 2021 and the papers published from January 1, 2015 to March 31, 2021 were included. The risk of bias was assessed by using Cochrane's risk of bias tool. Results: 524 studies were searched in domestic and foreign databases, and 7 studies were finally selected. In all studies, the treatment group was treated with oral traditional herbal medicine and the control group was treated with western medicine. Although the evaluation index was slightly different for each study, all studies used total efficacy rate index. In all 7 studies, the treatment group was more effective than the control group. Conclusions: Traditional herbal medicine can be an effective option in treating chronic pelvic inflammatory disease. Further high quality studies which include large number should be carried out to confirm the evidence and safety of traditional herbal medicine treatment.
