Objectives: This study reviewed randomized controlled trials (RCTs) investigating the effects of Neiguan (PC6) stimulation on blood pressure and suggests a better research process. Methods: We searched for RCTs for effects of Neiguan (PC6) stimulations on blood pressure published until July 2024 using six databases (PubMed, Oriental Medicine Advanced Searching Integrated System (OASIS), Korea Citation Index (KCI), Research Information Service System (RISS), Korean Studies Information Service System (KISS), and Science ON). In total, eight RCTs that met all the inclusion criteria were selected. Results: All the selected studies showed significant effects of Neiguan (PC6) stimulation on blood pressure. In most studies, Neiguan (PC6) stimulation was effective in stabilizing blood pressure and improving various indicators related to blood pressure. Conclusion: Neiguan (PC6) stimulation is an effective treatment for stabilizing blood pressure. However, the selected RCTs were short-term studies and had small number of subjects; so, long-term and large-scale studies are needed.

This study examined the effects of an art program based on multiple intelligence theory on children's creativity and spatial ability. The art education program focused on three processes : perception, production and reflection. Subjects were 68 five-year-old children. The experimental design was 'The Untreated Control Group Design with Pretest & Posttest'. ANCOV was employed for statistical analysis. Results were that the children in the experimental group scored significantly higher on creativity and spatial ability than the children in the control group. Results imply that an art education program based on multiple intelligence theory can be an effective teaching model for improving children's creativity and spatial ability.

In recent years, graph neural networks (GNNs) have been extensively used to analyze graph data across various domains because of their powerful capabilities in learning complex graph-structured data. However, recent research has focused on improving the performance of a single GNN with only two or three layers. This is because stacking layers deeply causes the over-smoothing problem of GNNs, which degrades the performance of GNNs significantly. On the other hand, ensemble methods combine individual weak models to obtain better generalization performance. Among them, gradient boosting is a powerful supervised learning algorithm that adds new weak models in the direction of reducing the errors of the previously created weak models. After repeating this process, gradient boosting combines the weak models to produce a strong model with better performance. Until now, most studies on GNNs have focused on improving the performance of a single GNN. In contrast, improving the performance of GNNs using multiple GNNs has not been studied much yet. In this paper, we propose gradient boosted graph neural networks (GBGNN) that combine multiple shallow GNNs with gradient boosting. We use shallow GNNs as weak models and create new weak models using the proposed gradient boosting-based loss function. Our empirical evaluations on three real-world datasets demonstrate that GBGNN performs much better than a single GNN. Specifically, in our experiments using graph convolutional network (GCN) and graph attention network (GAT) as weak models on the Cora dataset, GBGNN achieves performance improvements of 12.3%p and 6.1%p in node classification accuracy compared to a single GCN and a single GAT, respectively.

Objectives: This study reviewed experimental studies on the effects of herbal medicines in treating hyperthyroidism. Methods: We analyzed the experimental studies of herbal medicines done in Korea to treat hyperthyroidism that have been reported since 2000 by searching 4 Korean databases with the keyword "hyperthyroidism". Results: Two single herbal medicines and 15 complex herbal medicines were used in 15 experimental studies. There was 1 clinical study and 14 nonclinical studies, among them, 2 in vitro experiments and 12 in vivo experiments. It was confirmed that the herbal medicines used have improving effects on hyperthyroidism by inhibiting the oversupplied thyroid hormones and hypermetabolic symptoms. Conclusions: There should be further studies on the antioxidative effects and acting mechanisms of herbal medicines and more clinical studies on hyperthyroidism.

This study explores the effect of trade of Information Communications Technology (ICT) products and government's role, measured by three factors: Control of corruption, Government effectiveness, and Administrative tax level, on raising the economy across the East Asia-Pacific region. Secondary data were collected from the World Bank database of 21 countries over 12 years from 2006 to 2017. Applying the Panel corrected standard error model and running a robustness check based on the Dynamic panel data method, this research found that the exported ICT products, control of corruption, and government effectiveness could increase the economic income of a country in the region. The paper also provided the evidence indicating that the imported ICT products and the Administrative tax level are two harmful factors for economic growth. The major finding confirmed the useful contribution on improving government quality and its economy. First, improving the economy of a country always poses various challenges to its government. During the past decades, although much of the literature confirmed that exporting ICT products could promote an economy, very few studies investigated the role of Administrative tax level and the Government effectiveness. Second, there are only a few studies exploring the capability of government and the economic growth in the Asia-Pacific region.

Cultured meat has been gaining popularity as a solution to the increasing problem of food insecurity. Although research on cultured meat started later compared to other alternative meats, the industry is growing rapidly every year, with developed products evaluated as being most similar to conventional meat. Studies on cultured meat production techniques, such as culturing new animal cells and developing medium sera and scaffolds, are being conducted intensively and diversely. However, active in-depth research on the quality characteristics of cultured meat, including studies on the sensory and storage properties that directly influence consumer preferences, is still lacking. Additionally, studies on the combination or ratio of fat cells to muscle cells and on the improvement of microbiota, protein degradation, and fatty acid degradation remain to be conducted. By actively investigating these research topics, we aim to verify the quality and safety of cultured meats, ultimately improving the consumer preference for cultured meat products.

Across many industries, benchmarking is considered useful method to improve their service quality and achieve competitive advantage. Benchmarking, especially, has emerged as an increasingly important approach to improving the performance of logistics system and enables successful logistics services and doing good business in logistics services. There are no, however, literature approach for the relationship between benchmarking and port. It is the highest worth researching the application of benchmarking method on the port, since port is the most important component in supply Chain. Therefore, this paper tries to demonstrate the application of the benchmarking method on the port. To do this study, the literature approach developed by several researchers for logistics benchmarking is used as the basic framework. In addition, the following studies are executed: First, the survey of previous studies on logistics benchmarking. Second, finding the indicator and selecting the target in the port benchmarking. Third, the systematic execution schemes of the port benchmarking. Finally, based on the above studies, this paper provides a background for discussions on the future prospects for the application of the benchmarking method on the port.
