  • We have examined the perception and the knowledge of science-gifted students and general students in middle school level about high technology related to the science. The subjects of the investigation were 113 gifted students belonging to the universities' science-gifted education center in Busan or Ulsan, and 159 general students belonging to 2 middle schools in Busan. The survey was conducted with questionnaires on the perceptions concerning the high technology related to the science and the knowledge of a cellular phone without an antenna, and an LED(Light Emission Diode). The results of this survey concluded that the gifted students were more interested and aware of the high technology than the general students, these results are statistically significant. It has been found that there are significant differences between the gifted students and the general students in terms of the areas they want to learn, the source of information and the preferred learning method in advanced science and technology. Also, the gifted students were recognized to be better than general students in understanding an electromagnetic wave related to a cellular phone without an antenna, and a semiconductor connection with an LED.

  • Tea (Camellia sinenis) is a popular beverage consumed worldwide. Since green tea, mainly consumed in Asia, has various biological activities, green tea components became one of the most favorite candidates as a functional materials for cosmetics and functional foods. The biological activities of green tea for skin cue have been ranged from protection of epidermal cells to the stimulation of extracellular matrix (ECM) biosynthesis. Green tea polyphenols (GTPs), which are active ingredients of green tea, possess anti-inflammatory, anti-carcinogenic and immune potentiation properties as well as antioxidant. They also modulate intracellular signal transduction pathways. GTPs decrease ultraviolet (UV)-induced oxidative stress, thus suppress mitogen-activated protein kinase (MAPK) pathway and apoptosis in keratinocytes. In addition, GTPs prevent the Induction of inflammatory mediators, such as cyclooxygenase-2 (COX-2), interleukin-8 (IL-8), and vascular endothelial growth factor (VEGF) by tumor necrosis factor alpha $(TNF{\alpha})$ or chemical treatment in keratinocytes. GTPs treatment protects from chemical-or UV-induced skin tumor incidence in animal experiment. Besides, GTPs stimulate keratinocyte differentiation and proliferation of normal and aged epidermal cells, resectively, and suppress matrix metalloproteinases (MMPs) release. According to the progress of formulation study, green tea components will be guaranteed materials for the more effective skin cue products.

This study discussed the symbolic elements of the host country characteristics reflected in FIFA's World Cup event mascot. A total of 14 mascots of World Cup events were held from 1966 to 2018, and their materials can be divided into animals, plants, people and creations. The mascot was applied with the characteristic elements of regional specialties, the flag of the host country, symbolic attire, language of the hosting area, social issues and the mascot's dress, posture, props and expression characters of soccer events were used as symbolic elements. First of all, the implications of the research were that mascots were more strongly expressing the "football" signifying element, the theme of events, rather than regional characteristics. Second, the use of 'national flag' was highlighted among the elements of expressing regional characteristics. Third, 'animal' was preferred for mascot material. Fourth, mascots have become integrated with 'cultural perfumes' and play an extended role in raising social awareness. Implications derived from the classification of characteristics and symbol representation elements raised in this study will be used as a basis for the planning of international event mascots.
