  • The herbal medication Panax ginseng Meyer has widespread use in China, Korea, and other parts of the world. The main constituents of ginseng are ginsenosides, which include over 30 different triterpene saponins. It has been found that ginsenosides and their metabolites including Rg1, compound K, Rb1, Re, Rg3, and Rg5 exert anti-inflammatory activities by binding to the glucocorticoid receptor, modulating inflammation-related signaling, including NF-κB and MAPK signaling, and reducing levels of proinflammatory cytokines. Here, we review the recent literature on the molecular actions of ginsenosides in sepsis, suggesting ways in which they may be used to prevent and treat the disease.

  • Nowadays, lithium-ion battery has become more popular around the world. Knowing when batteries reach their end of life (EOL) is crucial. Accurately predicting the remaining useful life (RUL) of lithium-ion batteries is needed for battery health management systems and to avoid unexpected accidents. It gives information about the battery status and when we should replace the battery. With the rapid growth of machine learning and deep learning, data-driven approaches are proposed to address this problem. Extracting aging information from battery charge/discharge records, including voltage, current, and temperature, can determine the battery state and predict battery RUL. In this work, we first outlined the charging and discharging processes of lithium-ion batteries. We then summarize the proposed techniques and achievements in all published data-driven RUL prediction studies. From that, we give a discussion about the accomplishments and remaining works with the corresponding challenges in order to provide a direction for further research in this area.

  • Chronic lower back pain is a leading cause of disability in musculoskeletal system. Degenerative disc disease is one of the main contributing factor of chronic back pain in the aging population in the world. It is postulated that sinuvertebral nerve and basivertebral nerve main mediator of the nociceptive response in degenerative disc disease as a result of neurotization of sinuvertebral and basivertebral nerve. A review in literature is done on the pathoanatomy, pathophysiology and pain generation pathway in degenerative disc disease and chronic back pain and management strategy is discussed in this review to aid understanding of sinuvertebral and basivertebral neuropathy treatment strategies.

  • The competition for technological supremacy is unfolding in the high-tech field, and quantum computing can be determinant for economic and security ripple effects. The United States and China, leaders in quantum computing, have developed this field through adequate policies. The United States has fostered quantum computing through government policies and competition among private companies, while China has secured world-class technology through large-scale government investment and attracting foreign talent. In quantum computing, securing talented people is essential to guarantee independent technology development regarding academic attributes and security. We analyze quantum computing policies in the United States and China on a timeline and determine their policy trends. In addition, the policies for securing talent in these countries are reviewed, and the policy effects are compared based on literature analysis. Through the analysis of policy cases between the United States and China, bilateral policy implications for Korea are delineated.

  • Objectives: To review the concept of Moebius syndrome. Methods: Literature search was done to study definition, epidemiology, pathophysiology, clinical feature, and treatment of Moebius syndrome. Pubmed, RISS, Google scholarship and uptodate scholastic were used in the research. Search words were 'Moebius syndrome', 'treatment of Moebius syndrome'. Only English and Korean studies were assessed. Results: Moebius syndrome is rare disease characterized by nonprogressive congenital uni- or bi-lateral facial (VII cranial nerve) and abducens (VI cranial nerve) palsy. This facial palsy is found across the world, and its incidence is approximately 1 per 250,000. Moebius is diagnosed by clinical features. Facial palsy, eye abduction problem, limb deformities, global cerebral nerve impairment can be shown. Rehabilitation, smile surgery, and acupuncture can be used to treat this. Conclusion: Moebius syndrome's epidemiology, pathogenesis, treatment is still not fully revealed. It is known to be a congenital disease which didn't have exact treatment except surgery. But, it needs further study about exact treatment, diagnosis, and pathogenesis.

  • South Korea is currently facing many changes and challenges. To make matters worse, society has struggled to function as it did before COVID-19. This study describes the past and current COVID-19 situation to offer lessons on management during and after COVID-19. We provide implications from COVID-19 and the foundation for future disasters by employing the strengths, weaknesses, opportunities, and threats (SWOT) analysis and indigenous administrative conceptual framework on culture, institution, and instrument to add a circumstance perspective. This study used secondary data from prior research and literature. Resolutions for these policy issues are presented using the strength-opportunity (SO), strength-threat (ST), weakness-opportunity (WO), and weakness-threat (WT) strategies. We suggest utilizing instruments that consider diverse societies and preventing the disease with climate change by collaborating with social institutions. We hope these implications and resolutions will provide insights for the future and other countries.

  • Supporting individual or group learners through designing effective learning environment has been major concern for instructional technologists. In CSCL environment, the effectiveness of learning depends not only on the design of the learning incidences but also on that of psychological environment because in CSCL the learners encounter virtually a new environment deviate from the ordinary physical world. CSCL is one of the most demanding environment for learners and thus it requires a highly refined learner support mechanisms. The purpose of the research was to devise conceptual tools for supporting learners in CSCL environment. Especially, the researchers tried to develop special kinds of scaffolding that directly support the collaborative practice in the social and psychological dimension of the learner. Body of literature on scaffolding has been reviewed and effective CSCL environments were observed and analyzed. As a result of the study, the research proposes a new type of scaffolding, named as "collaboration scaffolding" as a conceptual tool for supporting learners in CSCL environment. Also the research suggests three subtypes of scaffolds as the most typical collaboration scaffolding; emotional scaffolds, facilitative scaffolds, and exploratory scaffolds.

  • This study examined China's public and government agenda setting in response to the Shanghai lockdown due to the COVID-19 pandemic. It employed content analysis, correlation, and Granger's causality tests to analyze 1,717 Weibo posts published by the public and the Shanghai Municipal Government from March 12 to June 1, 2022. The results showed that (1) pandemic statistics were the central attribute in the government agenda, while civil life, community management, and government and policies were the central attributes in the public agenda; (2) the government's agenda unidirectionally influenced the public agenda in terms of government policy attributes; and (3) the government and public agendas reciprocally influenced each other in terms of economic attributes. This study contributed to the existing literature by examining agenda-setting dynamics in a city closure event during the COVID-19 epidemic. It also extended existing methods by modeling implicit relationships between attributes in the public and government agendas.
