  • Korean ginseng (Panax ginseng) is associated with a variety of therapeutic effects, including antioxidative, anti-inflammatory, vasorelaxative, antiallergic, antidiabetic, and anticancer effects. Accordingly, the use of ginseng has reached an all-time high among members of the general public. However, the safety and efficacy of ginseng in transplant recipients receiving immunosuppressant drugs have still not been elucidated. Transplantation is the most challenging and complex of surgical procedures and may require causation for the use of ginseng. In this regard, we have previously examined the safety, immunological benefits, and protective mechanisms of ginseng with respect to calcineurin inhibitor-based immunosuppression, which is the most widely used regimen in organ transplantation. Using an experimental model of calcineurin inhibitor-induced organ injury, we found that ginseng does not affect drug levels in the peripheral blood and tissue, favorably regulates immune response, and protects against calcineurin inhibitor-induced nephrotoxicity and pancreatic islet injury. On the basis of our experimental studies and a review of the related literature, we propose that ginseng may provide benefits in organ transplant recipients administered calcineurin inhibitors. Through the present review, we aimed to briefly discuss our current understanding of the therapeutic benefits of ginseng related to transplant patient survival.

  • Influences of convergent services on the overall industry has become noticeable. Various services are becoming to converge into a single platform because of ever-hanging needs of digital service users. However, few studies have investigated how users' perception of convergent services as well as the quality of experience that service users have while using the convergent services. Therefore, this study aims at identifying perceived patterns of convergent services by IPTV users, which is one of the representative convergent-ervice platforms. It also aims at identifying the impact of perceived convergence pattern on the relationship between goal congruency among individual services and the quality of user experience. Two empirical studies were conducted to accomplish the research goals. We have constructed two prototypes of convergent digital services in the IPTV environment and conducted controlled experiments to verify the research hypotheses. The results indicate that design similarities of two services substantially influence the perceived patterns of convergent services. It was also found that the perceived convergent patterns have significant moderating effects on the impact of perceived goal congruence upon the quality of user experience. This paper ends with limitations as well as implications of the study results.

  • Coronavirus disease 2019 (COVID-19), which causes serious respiratory illness such as pneumonia and lung failure, was first reported in Wuhan, the capital of Hubei, China. The etiological agent of COVID-19 has been confirmed as a novel coronavirus, now known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is most likely originated from zoonotic coronaviruses, like SARS-CoV, which emerged in 2002. Within a few months of the first report, SARS-CoV-2 had spread across China and worldwide, reaching a pandemic level. As COVID-19 has triggered enormous human casualties and serious economic loss posing global threat, an understanding of the ongoing situation and the development of strategies to contain the virus's spread are urgently needed. Currently, various diagnostic kits to test for COVID-19 are available and several repurposing therapeutics for COVID-19 have shown to be clinically effective. In addition, global institutions and companies have begun to develop vaccines for the prevention of COVID-19. Here, we review the current status of epidemiology, diagnosis, treatment, and vaccine development for COVID-19.

  • In this paper, we present a practical implementation of the MPEG-21 multimedia framework for broadcasting and communication convergent services. MPEG-21 standard technology was exploited to build a convergent service framework. Using this framework, a service model and several scenarios have been successfully designed and implemented. In addition, interoperability, which is the main objective of a multimedia framework, especially in a convergent environment consisting of heterogeneous networks and various types of devices, has been addressed in detail. The experimental results show that the implemented test bed provides a next-generation multimedia service; that is, universal multimedia access (UMA), meeting the requirements of a broadcasting and communication convergent environment.

  • What is the role of right and left-brain in creative thinking? The current study is to address this question. Two empirical studies were performed to answer the question. First one is regarding the divergent thinking and right-brain connection. Second one is regrading the convergent thinking and left-brain connection. Empirical study showed that both of divergent and convergent thinking were asymmetrically related to creativity. Divergent thinking was connected to right-brain and convergent thinking was connected to left brain.

  • This study examines network compositions of convergent research relationships in the field of high-tech convergence technology and investigates the relational linkages among various research fields. A network analysis was performed to evaluate the High-Tech Convergence Technology Development Program, a convergent research funding program of the National Research Foundation of Korea (NRF); the dataset covered the 2009-2011 period. The analytical results reveal the hidden network structure of convergent research relationships and demonstrate that the formation of convergent research might be enhanced by interdependent pressures placed on various research fields but also by accumulated research capabilities that each of these fields possessed and which could be used to converge specialized and heterogeneous research areas and interests.

  • The purpose of this research was to analyze the convergent approaches for creativity in elementary mathematics textbooks in Korean and the united States. Convergent approaches have emphasized since NCTM(2000) consistently includes 'connections' as an important factor in mathematics curriculum and KOFAC(Korea Foundation for the Advancement of Science & Creativity) initiated the STEAM(Science, Technology, Engineering, Arts, and Mathematics) in mathematics and science education. For this research, two elementary mathematics textbooks were analyzed focused on their contexts and contents: Korean National Elementary Mathematics Textbooks and Navigations in Numbers, Data, and Space. In both textbooks, it was not easy to find so called the convergent approach in a real sense, but they use some contexts for connections between mathematical concepts and real world phenomena. For the enhancement of convergent approaches in mathematics education, we need to have a broader sense in the convergent approaches and develop various meaningful materials.

  • The research reviews the logical approach based on the creative thoughts. The two logical approaches, including deductive convergent and inductive divergent are discussed with why-why techniques and how-how techniques. While the deductive thinking is vertical logic for interconnected hierarchical and deep domains, the inducive thinking is horizontal logic for mutually exclusive and collectively exhausted frameworks. The creative thinking comes from the reversing the logic and lessening the premise of convergent and divergent approaches.

  • A wide variety of convergent digital products are emerging through the combination of multiple independent digital technologies. Digital convergence provides new revenue sources for businesses and new ways of satisfying individual needs of consumers. Despite its business and consumer implications, little research has addressed how people perceive or evaluate convergent products. This study aims at understanding how consumers interpret and evaluate convergent digital products by conducting two consecutive studies. Firstly, a survey was conducted to understand how people interpret convergent products in three ways suggested by the conceptual combination theory based in cognitive science. Secondly, an experiment was conducted to investigate the impact of combination strategies and product similarities on user evaluation of convergent products. Study results indicate that similarity of constituent products has a substantial effect on the interpretation of concept combination strategies. Moreover, combination strategy and product similarity were found to have substantial effects on user comprehension, perceived newness, and preferences for convergent products. This paper ends with an examination of the implications and limitations of the study results.

  • In this paper, we try to define and classify the concepts of Convergent Research of Korean-Western Medicine (CRKWM) to clarify the goals of research. In addition, some suggestions that are necessary to promote the CRKWM were made. The results are as follows. First, the CRKWM should be used as a concept that refers to 'interdisciplinary research' jointly conducted by experts in both Korean and Western medicines beyond their own fields. Second, True CRKWM is an "eclectic combination of East-West" that combines the advantages of traditional Korean medicine and western medicine to create a new field; it is necessary to redefine the concept of 'Integrative medicine', which is used in different context by the traditional Korean medicine and western fields in Korea, as an "eclectic combination of East-West" type. Third, In order to promote the CRKWM, it is necessary to convert the current dual medical system of relativism to one of pluralism. Forth, In order for CRKWM to be promoted, methodologies, theories, and models that become the backbones of convergence should be developed. As of now, systems medicine and network science are the best fit. Fifthly, In order to promote convergent clinical research, the development of Korean-Western diagnostic model that integrates the pathologies of Western medicine and symptoms of Korean medicine is urgent. Lastly, Mutual understanding between Korean and Western medicine fields should be preceded in order for CRKWM to be stimulated.
