This paper analyzes changes in the export potential and competitiveness of China, Japan, and Korea. The analysis of Japan's export market share reveals that in sectors where Korea's potential was strong in the early 1990s, Japan's market share diminished. This suggests the possibility that Korea was catching up with Japan, eating into Japan's market share. The same analysis of Korea's export market share in the 2000s shows, for items in which China's export potential was high, Korea's market share has declined comparatively since 2010, with the tendency growing much larger. China's export potential continues to expand in markets for Korea's key export products, making it difficult to rule out the possibility that Korea's competitiveness in key export products will be hindered, driven by the catching up of China. To respond to these challenges, it is important for Korea continuously to foster and enhance creative and core capabilities that latecomers will not easily be able to emulate.

Recent studies have indicated that boys show better scientific achievements compared to those of girls. It is also a general conception that boys would be better than girls in terms of scientific creative performances and potential, although there have been few studies to support the general opinion. As the gifted education in Korea is progressing very rapidly, the importance of understanding the creative characteristics of gifted boys and girls has been increased. In the present study, we have compared and analyzed three different measures of creativity utilizing 135 gifted students (77 boys and 58 girls) to provide an empirical evidence for the different degrees of creative performances between gifted boys and girls. The instruments used to measure diverse aspects of creativity include the Torrance Test of Creativity (TTCT), the Test of Creative Problem-solving and Finding in Science (CPFS), and the Creative Behavioral Checklist in Science(CBCS). The results of the study indicate that girls, rather than boys, showed better creative performances, demonstrating moderately higher average scores on the three creative measures used in the study. The results are in contrast to people's general conception that boys would be more creative than girls. Implications of the study in connection with identification and educational practices for gifted education program have been discussed.

β-Amyrin is a pentacyclic triterpene widely distributed in leaves and stems worldwide. The ability of β-amyrin to induce the production of reactive oxygen species (ROS) in microorganisms suggests its potential as an antimicrobial agent. Thus, this study aimed to elucidate the antibacterial mode of action of β-amyrin. We treated Escherichia coli cells with β-amyrin and found that it triggered ROS accumulation. Excessive stress caused by ROS, particularly hydroxyl radicals, induces glutathione (GSH) dysfunction. GSH protects cells from oxidative and osmotic stresses; thus, its dysfunction leads to membrane depolarization. The resultant change in membrane potential leads to the release of apoptotic proteins, such as caspases. The activated caspases-like protein promotes the cleavage of DNA into single strands, which is a hallmark of apoptosis-like death in bacteria. Apoptotic cells usually undergo events such as DNA fragmentation and phosphatidylserine exposure, differentiating them from necrotic cells, and the cells treated with β-amyrin in this study were positive for annexin V and negative for propidium iodide, indicating apoptosis-like death. In conclusion, our findings suggest that the antibacterial mode of action of β-amyrin involves the induction of ROS, which resulted in apoptosis-like death in E. coli.

Objectives Banha-sasim-tang (BST), which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb-drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb-drug interactions between BST extract and midazolam (MDZ) in mice. The area under the plasma concentration-time curve (AUC) of MDZ and 1'-hydroxymidazolam (1'-OH-MDZ) was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg). Results It was found that the AUC of MDZ and 1'-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

In the present study we have compared and analyzed three different measures of creativity in 135 gifted and 161 normal students to understand the nature of creativity and to propose the guideline for measuring creativity. The instruments used to measure creativity in this study are the Torrance Test of Creativity Thinking (TTCT), the Test of Creative Problem solving and Finding in Science (CPFS), and the Creative Behavior Checklist in Science (CBCS). The TTCT is the most widely used divergent thinking test and measures creativity in the aspect of domain-generality. The CPFS and the CBCS were developed for the purpose of this study and measure domain-specific creativity in the area of Science. The findings of this study revealed that gifted students are significantly more creative compared to normal students in all measures of creativity used in the study. The biggest difference between the gifted and normal students was found in the aspect of CPFS. This study implies that creativity, which is considered less useful to identify gifted students compared to achievement or IQ scores, is the important factor to consider for judging giftedness. The low correlations revealed among the TTCT, CPFS, and CBCS imply that the three measures of creativity address relatively different aspects of creativity. The results also suggest that it is essential to consider multiple criteria of creativity not to overlook potential creative students in the area of science. Implications of the study in connection with the identification and educational practices for gifted education program is discussed.

Korean ginseng (Panax ginseng Meyer) is a traditional herb used across the world to treat various diseases. Although, red ginseng is this herb's most famous product and has demonstrated diverse pharmacological activities, white ginseng (WG) is another ginseng product that is made fresh and individually regulated in Eastern Asia. Red and white ginseng show different characteristics due to distinct processing steps despite originating from the same plant, and the drug interactions induced by WG have not been well documented. Selegiline is a selective monoamine oxidase (MAO) inhibitor used as an antidyskinetic and antiparkinsonian agent. Here we developed a quantification method for selegiline in mouse plasma using a C8 stationary phase in triple quadrupole-mass spectrometry (LC-MS/MS) with multiple reaction monitoring (MRM). The validated LC-MS/MS method was successfully applied to determine the potential interaction with WG extract (0.1 g/kg/day) pre-administered for 4 weeks. The $AUC_{0-240min}$ of selegiline was altered due to a decrease in the absorption of selegiline with repeated administration of WG extract.
