Background: The findings of currently available studies are not consistent with regard to the association between the risk of cancer and ginseng consumption. Therefore, we aimed to evaluate this association by conducting a meta-analysis of different studies. Methods: To systematically evaluate the effect of ginseng consumption on cancer incidence, six databases were searched, including PubMed, Ovid Technologies, Embase, The Cochrane Library, China National Knowledge Infrastructure, and Chinese VIP Information, from 1990 to 2014. Statistical analyses based on the protocol employed for a systematic review were conducted to calculate the summary relative risks (RRs) and 95% confidence intervals (CIs). Results: We identified nine studies, including five cohort studies, three case-control studies, and one randomized controlled trial, evaluating the association between ginseng consumption and cancer risk; these studies involved 7,436 cases and 334,544 participants. The data from the meta-analysis indicated a significant 16% lower risk of developing cancer in patients who consumed ginseng (RR = 0.84, 95% CI = 0.76-0.92), with evidence of heterogeneity (p = 0.0007, $I^2$ = 70%). Stratified analyses suggested that the significant heterogeneity may result from the incidence data for gastric cancer that were included in this study. Publication bias also showed the same result as the stratified analyses. In addition, subgroup analyses for four specific types of cancer (colorectal cancer, lung cancer, gastric cancer, and liver cancer) were also performed. The summary RRs for ginseng intake versus no ginseng consumption were 0.77 for lung cancer, 0.83 for gastric cancer, 0.81 for liver cancer, and 0.77 for colorectal cancer. Conclusion: The findings of this meta-analysis indicated that ginseng consumption is associated with a significantly decreased risk of cancer and that the effect is not organ specific.

This paper is a study of testing on-board signalling equipment in advanced high speed rail at the maximum speed of 400km/h. The on-board signalling equipment in advanced high speed rail provides operating information to the driver when operating at ATC, ATS, and ATP sections, and maintains safety from driver oversight, signalling equipment malfunction, natural disasters and so on. Since the testing train performance of advanced high speed rail at 400km/h must include the function test of on-board signalling equipment, this thesis focuses on the function test of on-board signalling equipment and analyze the necessity of the test at the maximum speed. Finally, it is suggested to change some infrastructure and to use specific test methods to test the train performance at the maximum speed in high speed line ATC section.

The explosive growth of data and the rapidly changing technical social evolution new analysis paradigm for predicting and reacting the future the past and present ig data. Prescriptive analysis has a fundamental difference because can support specific behaviors and results according to user's goals with defin researchers establish judgments and activities achiev the goals. However research methods not widely implemented and even the terminology, Prescriptive analysis, is still unfamiliar. This paper thus propose an infrastructure in the prescriptive analysis field with key considerations for enhancing capability of researchers through a case study based on InSciTe Advisory developed with scientific big data. InSciTe Advisory system s developed in 2013, and offers a prescriptive analytics report which contains various As-Is analysis results and To-Be analysis results 5W1H methodology. InSciTe Advisory therefore shows possibility strategy aims to reach a target role model group. Through the availability and reliability of the measurement model the evaluation results obtained relative advantage of 118.8% compared to Elsevier SciVal.

QR(Quick Response) Code has been developed to provide greater storage capacity and more functionality compared to 1D bar codes. With the emergence of increasingly mobile devices equipped with cameras such as smart-phones and tablets, QR codes have become very popular and more important in mobile businesses. Typically, most QR codes are used as a URL link for redirecting users to webpages. However, the URL based QR codes are required to be connected over the internet and to be run a server. This can incur unnecessary traffics in the Internet. Furthermore, it is not suitable for the country lagging behind others in its network infrastructure. In this paper, we propose a server-less ${\mu}$-webpage to provide mobile web services and be optimized for the capabilities and limitations of QR Code. We have implemented the ${\mu}$-webpage in Android, and the results showed that the proposed mechanism can provide web-services without requiring extra servers or incurring mobile traffic data compared to the URL-based QR Codes.

Due to globalization, more foreign-owned small businesses have been joining the South Korean economy. In order to better support the growth, this study's purpose is to identify foreign entrepreneur demographics and company information as well as entrepreneurial motivations and perceived success factors. To fulfill these goals, a survey of 98 immigrant entrepreneurs from 31 countries doing business within the local Korean market was conducted. The results show that most foreign-owned small businesses are service-oriented and primarily started for intrinsic reasons. It was also identified that the perceived business success determinants that the government can most directly affect are skills-based, rather than infrastructure or financially oriented. Furthermore, top issues include unreliable employees, language barrier and too much competition. The findings of this study are particularly relevant to both academics and policy makers alike because almost no prior foreign entrepreneur-focused research has been conducted in Korea.

Objectives: The purpose of this study is to review the clinical research trends of postpartum pelvic organ prolapse and to recognize the efficacy of Korean medicine intervention. Methods: Based on seven domestic and foreign databases, including Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Journal of Korean Obstetric and Gynecology, Cochrane Library Central, Pubmed, China National Knowledge Infrastructure (CNKI) and WangFang Med Online, we analyzed the clinical trials using Korean medicine intervention, which included acupuncture and herbal medicine. Data retrieval was carried out on May 18 to 20, 2020, and a total of 13 papers were included. Results: All papers were published in China and it contains nine randomized controlled trials, three clinical trials, and one case. The most frequently used intervention was herbal medicine, and Bupleuri Radix, Cimicifugae Rhizoma were used. The treatment group treated by Korean medicine intervention was more effective than the control group. Also, there were no significant side effects of Korean medicine. Conclusion: This study shows that Korean medicine can be effective and safe medical alternatives or options for pelvic organ prolapse patients. However, to laying the foundation of clinical guidelines and applying it to the real-world clinical scene, further follow-up research is needed.

This study is aimed to discover the deciding factors in senior employment programs for improving the quality of life for the elderly. The dependent variable used in this study was the quality of elderly persons. Personal and familial characteristics, and the community involvement of the elderly were used as independent variables in a Multiple Regression analysis. First, the most influential factor encouraging the elderly to participate in a senior employment promotion program was previous experience of senior employment programs. Second, health condition, residence in city areas, experience of volunteer work, and knowledge of senior employment programs had positive effects on the continuous participation of the elderly men and women. However, living arrangements had an effect solely on elderly men, and home ownership and participation in economic activities had effects solely on elderly women. Third, the life quality of the elderly was affected differently by sex. Health condition had the greatest effect on male elderly persons, whereas, the effective variable, the composition of the family had the most effect on female elderly persons. Thus, active campaigns through various mass media and information sessions are needed to promote participation in senior employment programs, according to the above mentioned deciding factors. In particular infrastructure providing the elderly with more volunteer work opportunity needs to be built for baby boomers to improve their quality of life. In addition, diversified senior employment programs are needed. Because the elderly living in city areas are more willing to participate in senior employment programs, specialized programs suitable for the elderly in city areas are needed. The government should also prepare programs that help the elderly stay healthy while they are working.

Road is one of the infrastructure facilities, on which lines include various information for guiding a smooth traffic flow. This line marking work is continually removed and re-marked during maintenance. However, some problems exist when the line marking work is conducted. Traditional methods of using grinders and torches have risk of repetitive skill, and workers are exposed directly to the hazardous situations. Moreover, even though the equipment has developed, the line removing work induces environmental contamination and pollution line on the road. Therefore, this study can become one of the eco-friendly cleaning technologies using dry ice blaster equipment, and the new development of equipment will improve method of pavement marking removal. Also, it can introduce innovative automation in construction.

This paper is to provide for an analysis on the trade adjustment assistance program and the Case study affected by international trade and FTA. The paper offers a legal study on analysis about Korea's Trade Adjustment Assistance Law for the Manufacturing Industries, USA's TAA. and Japan's law for Industry revival. In general, USA's TAA measures are defined as assistance actions for business enterprises, farmers and manufacturing industries workers. We exclude farmers and fishermen under Korea's Trade Adjustment Assistance Law for the Manufacturing Industries's business enterprises and workers, but we give them the systemic supports under korea's special assistance law for the farmers and fishermen and so on after FTA. Especially this focuses on the trade adjustment assistance case about both Korea's agriculture-farmer assistance from FTA and USA's TAA from workers in layoffs of trade-impacted communities. Korea has provided TAA to the sphere of agriculture after special legislation in Korea-Chile helping closed orchard, modernizing high quality producing facility for agriculture competition, producing superior fruit saplings, and constructing the distribution center in the producing district. But for US-Korea FTA and rapid increase of import by FTA expansion, we must prepare such indemnity systems for loss as cash benefit and wider aids for closed farm. The USA's TAA program targets manufacturing workers affected by international trade, who may have fewer transferable skills and face greater challenges to reemployment than other dislocated workers. A large majority sought some assistance from their one-stop center. Relatively small numbers chose to enroll in training, but those who did it often used this opportunity to chart a new career path. Finally, we learned the importance of education and discipline from USA cases. The fast and accurate information providing can raise efficiencies. The infrastructure can maximize the effect of TAA. The effective application would help us get over difficulties of TAA at hand.
