Purpose: The purpose of this study was to evaluate the effectiveness of non-pharmacologic interventions for chronic nonspecific low back pain (CLBP) in adults aged 18-64 years. Methods: We searched for potentially relevant randomized controlled trials and non-randomized controlled trials through five Korean electronic databases (i.e., Korean Studies Information Service System, Research Information Sharing Service, Korean Medical Database, KoreaMed, and National Assembly Library) published from January 2010 to May 2019. Two investigators independently selected the studies based on the criteria and assessed risk of bias in the included studies. We estimated the effect size of interventions using Comprehensive Meta Analysis 3.3. Results: Of 10,151 studies, 26 studies met the inclusion criteria and 15 studies were included in the meta-analysis. Exercise reduced low back pain (Hedges's g=-1.53, 95% CI: -2.22 to -0.85) and pain-related disabilities (Hedges's g=-0.92, 95% CI: -1.40 to -0.45). We found that taping was effective in decreasing low back pain (Hedges's g=-1.12, 95% CI: -1.51 to -0.73) and pain-related disabilities (Hedges's g=-0.50, 95% CI: -0.93 to -0.07). Manual therapy yielded a marginally significant reduction in low back pain (Hedges's g=-2.32, 95% CI: -4.64 to 0.00), the therapy was not effective in decreasing pain-related disabilities. Conclusion: Although there was little evidence for the effectiveness of manual therapy in adults with CLBP, exercise and taping were effective to relieve pain and pain-related disabilities. Based on these findings, we suggest the development of non-pharmacologic interventions or a nursing intervention protocol for the CLBP management. Also, nurses should consider implementation of effective non-pharmacologic interventions for CLBP.

Objectives The purpose of this study is to evaluate the effectiveness of Chuna therapy for primary dysmenorrhea. Methods Researchers searched on 7 electronic databases (Pubmed, National Digital Science Library, China National Knowledge Infrastructure, Wangfang med online, Korean Studies Information Service System, Research Information Sharing Service and Oriental medicine Advanced Searching Integrated System). The search included Korean, English, Chinese reports and there was no limit on the search period. All of randomized controlled clinical trials (RCTs) that used Chuna manual therapy for primary dysmenorrhea were selected. Results 27 RCTs met required condition. Meta-analysis showed positive results for Chuna manual therapy for primary dysmenorrhea in terms of therapeutic effects and reduction of symptom scores compared to west medicine, herbal medicine, acupucture and other treatments. Conclusions Above results showed that performing chuna is effective in treating dysmenorrhea. However, in some studies, there was no statistic significance between the experimental group and the control group. Also, according to Cochrane Risk of Bias (RoB) evaluation method, quality of the studies were not high enough. Since most of the materials were in Chinese, more high-quality clinical trials about Chuna therapy for primary dysmenorrhea are needed in Korea.

Objectives : To evaluate the effectiveness of Chuna Manual Therapy for adhesive capsulitis by a systematic review manner. Methods : Five foreign electronic databases (Pubmed, Ovid-medline, Embase, Cochrane library, Chinese Academic Journals (CAJ)) and two Korean medical electronic databases (Oriental Medicine Advanced Searching Integrated System (OASIS) and Research Information Sharing Service (RISS)) were searched to find all randomized controlled trials (RCTs) using Chuna Manual Therapy as a treatment for adhesive capsulitis. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Twenty-one RCTs met our inclusion criteria. The meta-analysis showed positive results on the use of Chuna Manual Therapy combined with acupuncture or exercise therapy in terms of the efficacy rate and pain using the Visual Analogue Scale (VAS), compared to acupuncture or exercise alone [SMD-1.81 (95% CI & -2.54, -1.08), P<0.001, RR 1.19 (95% CI 1.14, 1.23), P<0.001)]. Positive results in terms of efficacy rate were also obtained comparing Chuna Manual Therapy to acupuncture alone [RR 1.10 (95% CI 1.02, 1.18), P=0.01]. Conclusions : Our systematic review found favorable results on the effectiveness of Chuna Manual Therapy for pain and efficacy rate of adhesive capsulitis. However, evidence was limited due to the lack of well-designed RCTs. More qualified clinical trials are needed to obtain stronger evidence.

In this study, we performed an empirical study to decide whether the use of the TPM and TPM level of understanding of the parameters affect directly the TPM performances or not. In a TPM analysis of TPM activity factors, all factors directly affect the level of understanding. Especially individual improvement activities and autonomous activities are directly affect the performance, rather than depending on the degree of understanding of TPM to influence utilization and analyzed. In addition, training on the utilization and directly or indirectly to affect performance were analyzed. Companies take advantage of the TPM and TPM activities, the company's level of understanding of the factors and the TPM factors are closely dependent upon. Ongoing communication among TPM activities and the steady profits and sharing of comments on the risk based on the level of understanding of a TPM will be an important element in the company's performance.

Biotechnology is certainly one of the major landmarks in the 20th century history of science. It may produce enormous utility to human beings, but at the same time, it carries huge potential risks to the environment and public health. Thus, with a view to securing safety for the environment and public health in relation to the development and use of living modified organisms (LMOs), the Cartagena Protocol on Biosafety was adopted, in which a regulation Procedure as to the transboundary movements, transportation, handling, and use of LMOs were drawn up. In order to prepare for the entry into force of the Protocol, the Republic of Korea legislated the "Act on the Transboundary Movements of living modified organisms(hereinafter referred as the 'Act')" in Mar 2001, and has pre-announced the enactments of the enforcement ordinance and the enforcement regulation to the Act. Pursuant to the Act, the Ministry of Commerce, Industry and Energy, as a Competent National Authority, is making efforts to implement domestic biosafety schemes in cooperation with other bio-related government ministries. In order for these efforts to reap fruits, industry, academia, and research institutions should cooperate with one another, and civic groups and NGOs should narrow the differences in opinions and timely respond to the fast-changing situations. Focusing on the precautionary principle, the Protocol puts a great emphasis on the importance of information sharing amongst countries, and the Act also follows this principle. In order to gurantee biosafety, countries around the world, including the ROK, agreed to establish National Biosafety Clearing, designed to provide the information on the export/import of LMOs, R'||'&'||'Ds, risk assessment, safety control, etc. and register it on the CBD Central Biosafety Clearing House.e.

Nowadays, a capital flow and intimacy of financial system among countries have been increasing in global financial environment. So it is easily possible that the risk of some countries which are in financial crisis infects other countries in the world. A recent global financial crisis reminds countries in East Asia of advancing the financial cooperation as well as financial integration. Countries in East Asia agreed with the Chiang Mai Initiative to prevent a recurrence of financial crisis in East Asia. A bilateral swap arrangement of the CMI has several purposes in order to offer foreign currency liquidity against economic crisis, remove the opportunity cost of foreign exchange reserve, push ahead the financial integration, increase the export-import logistics and so on. This paper analyzes the effect of financial cooperation in East Asia on the export-import logistics with random effect estimation and fixed effect estimation. As a result, each of country in East Asia is able to increase almost 10.3% of the export-import logistics on average.

Recently, the processing and utilization of big data, which is generated by the spread of smartphone, SNS, and the internet of things, is emerging as a new growth engine of ICT field. However, in order to utilize such big data, De-identification of personal information should be done. De-identification removes identifying information from a data set so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information, thus it attempts to balance the contradictory goals of using and sharing personal information while protecting privacy. De-identified information has also been re-identified and has been controversial for the protection of personal information, but the number of instances where personal information such as big data is de-identified and processed is increasing. In addition, many de-identification guidelines have been introduced and a method for de-identification of personal information has been proposed. Therefore, in this study, we describe the big data de-identification process and follow-up management, and then compare and analyze de-identification methods. Finally we provide personal information protection issues and solutions.

This paper presents a reinforcement learning framework for stock trading systems. Trading system parameters are optimized by Q-learning algorithm and neural networks are adopted for value approximation. In this framework, cooperative multiple agents are used to efficiently integrate global trend prediction and local trading strategy for obtaining better trading performance. Agents Communicate With Others Sharing training episodes and learned policies, while keeping the overall scheme of conventional Q-learning. Experimental results on KOSPI 200 show that a trading system based on the proposed framework outperforms the market average and makes appreciable profits. Furthermore, in view of risk management, the system is superior to a system trained by supervised learning.
