  • Objectives: Medicinal plants are vital sources of bioactive compounds that are useful for the treatment of patients with snake bites or are indirectly applicable for boosting the effects of conventional serum therapy. These plants are being used traditionally by local healers and tribes for the treatment of patients with snake bites and therefore can be used as an alternative against snake envenomation. Scientifically, using the secondary metabolites of plants to neutralize venom enzymes has an extra benefit of being based on traditional knowledge; also, the use of such metabolites for the treatment of patients with snake bites is cheaper and the treatment can be started sooner. Methods: All the available information on various secondary metabolites exhibiting venom neutralizing ability were collected via electronic search (using Google books, Pubmed, SciFinder, Scirus, Google Scholar, and Web of Science) and articles of peer-reviewed journals. Results:Recent interest in different plant has focused on isolating and identifying of different phytoconstituents that exhibit Phospholipase A2 activity and other venom enzyme neutralizing ability. In this support convincing evidence in experimental animal models are available. Conclusion: Secondary metabolites are naturally present, have no side effect, are stable for a long time, can be easily stored, and can neutralize a wide range of snake enzymes, such as phospholipase A2, hyaluronidase, protease, L-amino acid oxidase, 5'nucleotidase, etc. The current review presents a compilation of important plant secondary metabolites that are effective against snake venom due to enzyme neutralization.

  • The Life Cycle Assessment (LCA) as an environmental impact assessment tool has received increasing attention over the years. Unlike the water footprint (WF) and carbon footprint (CF) assessments whose focus is only on a single environmental aspect, the LCA systematically analyzes the different impacts along the entire life cycle, making possible the identification of potential environmental tradeoffs. In Korea, LCA has drawn much attention from both industry and academia since the mid-90s. However, the level of Korea-related LCA studies with respect to different sectors in the past 20 years has not been analyzed. This study, therefore, sought to assess the status of environmental Life Cycle Assessment (LCA) studies in Korea, with a view to understanding the current level of sustainability reporting and identify potential research gaps. Online searches of English written articles published between 2000 and 2019 were conducted on Google, Google scholar, Scopus, and Web of Science databases using the Keywords "life cycle assessment", "lca", and "Korea." At the end of the search, about 88 LCA related studies were identified for Korea within the study period. Majority of these studies focused on the construction (49%) and energy (31%) sectors with fewer environmental studies on the transportation (9%), manufacturing (8%), agriculture (2%), and information and communication (1%) industries. Based on publication trend, results show that LCA studies in Korea have been on the rise in the past 20 years, even though the number of publications has not followed a constant pace. In comparison with the economic sectors of the country, reports show an inadequacy in the coverage of major industries of growing economic relevance like the tourism, health, and agriculture, suggesting a need to further increase and improve LCA related studies in these sectors.

  • Purpose: The purpose of this paper was to analyze research papers using movies and to introduce a practical instruction in cinema education for nurse educators in Korea. Method: The computerized database of PubMed, Google scholar, NDSL, CINAHL, and PsychINFO were used to generate relevant literature. Sixteen studies were published between 1990 and 2011 and were included in this review. These papers were analyzed using the matrix method suggested by Garrad (2007). Results: The first paper using movies in nursing education was performed in 1995. There were 16 studies on this issue and classified into one qualitative and 15 quantitative research. Because psychiatric mental health nursing was the main course, movies relating to mental illness were mainly considered. Most papers used questionnaires developed by researchers and discussions regarding the course. The key findings in these papers were all positive. Conclusion: The critics and syntheses in these papers emerged into seven overarching merits of cinema education and that lead to conduct cinema education to deepen students' understanding and to evoke empathy, critical thinking, entertainment, and intimacy. In addition, cinema education was safe and economical. This study recommends discovering suitable films and developments in both instruction process and educational evaluation tools.

  • Objectives : The purpose of this study is to present the clinical practice guidelines for colorectal cancer through the analysis of existing clinical practice guidelines and randomised clinical trials (RCTs) in Western and Chinese medicine. Methods : The data related to Western and Oriental medical treatment of colorectal cancer were collected using various search engines such as Google Scholar, KIOM OASIS, PUBMED and Jisan library of Daejeon university. Results & Discussion : Colorectal cancer is the third most common cancer in Korea. In recent studies, applying combined oriental and western medicine can improve the survival, quality of life, immune function, and suppress of tumor growth in colorectal cancer. However there isn't still an objective and systemic clinical guideline for colorectal cancer, so we have difficulty in clinical application. This study will be a preliminary study to establish clinical practice guidelines of Korean Medicine for colorectal cancer. Conclusions : Further objective and systemic clinical studies related to Korean Medicine are needed to develop more advanced clinical practice guidelines of colorectal cancer.

  • Purpose: Breast cancer is an important cause of cancer-related death in women. Numerous studies have evaluated the association between the insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene and breast cancer risk. However, the specific association is still controversial rather than conclusive. Therefore, we performed a meta-analysis of related studies to address this controversy. Methods: PubMed, EMBASE, Google Scholar and the Chinese National Knowledge Infrastructure databases were systematically searched to identify relevant studies. A meta-analysis was performed to examine the association between the I/D polymorphism in the ACE gene and susceptibility to breast cancer. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. Results: 10 separate studies of 7 included articles with 10,888 subjects on the relation between the I/D polymorphism in the ACE gene and breast cancer were analyzed by meta-analysis, and our results showed no association between the I/D polymorphism in the ACE gene and breast cancer in total population and different populations. No publication bias was found in the present study. Conclusions: The ACE I/D polymorphism may not be associated with breast cancer risk. Further large and well-designed studies are needed to confirm this conclusion.

  • Background: We aimed to comprehensively review the evidence for using sputum DNA to detect non-small cell lung cancer (NSCLC). Materials and Methods: We searched PubMed, Science Direct, Web of Science, Chinese Biological Medicine (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang, Vip Databases and Google Scholar from 2003 to 2013. The meta-analysis was carried out using a random-effect model with sensitivity, specificity, diagnostic odd ratios (DOR), summary receiver operating characteristic curves (ROC curves), area under the curve (AUC), and 95% confidence intervals (CI) as effect measurements. Results: There were twenty-two studies meeting the inclusion criteria for the meta-analysis. Combined sensitivity and specificity were 0.62 (95%CI: 0.59-0.65) and 0.73 (95%CI: 0.70-0.75), respectively. The DOR was 10.3 (95%CI: 5.88-18.1) and the AUC was 0.78. Conclusions: The overall accuracy of the test was currently not strong enough for the detection of NSCLC for clinical application. Dscovery and evaluation of additional biomarkers with improved sensitivity and specificity from studies rated high quality deserve further attention.

  • Purpose - The purpose of this study is to provide a systematic literature review related to environmental upgrading in Global Value Chains (GVCs) and suggest possible future research agendas in advancing environmental upgrading and ultimately GVC boundaries. Research design, data, and methodology - The academic databases such as Science Direct, EBSCO, ProQuest and Google Scholar were explored using a structured keywords searches to identify relevant research in the environmental upgrading area in GVCs. Only relevant papers were selected after reading the abstracts, and analyzed using qualitative content analysis. Results - Overall analysis of the literature review suggests two critical developments in the field of environmental upgrading. The first and foremost major development is an enhanced understanding of environmental upgrading as a concept and phenomenon. The second significant development is that environmental upgrading has been empirically proven to be fundamentally based on relationships and power structures within GVCs. Conclusions - Environmental upgrading in GVCs has been studied individually and not in relation to financial outcomes and social upgrading. Hence, the relationship of environmental upgrading with financial outcomes and social upgrading needs to be investigated. Furthermore, the impact of the interaction of varying institutional structures on environmental upgrading is worthy of future study.

  • Purpose: We present improvements to the Korean home visiting healthcare service based on analysis of Korean home visiting healthcare services considering recent sociodemographic changes and demands for healthcare services. Methods: This is a review study in which the results are derived through a literature review and data analysis. We collected data through a search of electronic databases, Google Scholar, and governmental websites. Results: Changes in Korean home visiting healthcare services are classified into four stages: 'introduction (1990-2000)', 'pilot project (2003-2006)', 'nationwide expansion (2007-2012)', 'various types (2013-2018)'. Korean home visiting healthcare service based on public health centers has achieved outcomes such as improved health behavior and health management, increased health management ability, and establishment of comprehensive healthcare infrastructure. Conclusion: In the future, the demand for home visiting healthcare service will increase steadily because of deepening social polarization, rapid aging of the population, and increases in chronic diseases. To improve health management and health equity, we suggest that Korean home visiting healthcare service will expand to all the people as a core public health service. It is necessary to establish a management team for various types of home visiting healthcare service in the public health center.
