The medical bed developed in this study is an electrically driven segmental keyboard. First describe the instrument of the segmental bed specially designed for pressure ulcer prevention, then the motor control system and pressure ulcer prevention operation of the bed. The main factor of pressure ulcer generation is displayed as body pressure x time, and when the keyboard falls, the body pressure becomes zero, and the pressure becomes higher than the threshold even if the body pressure is above the threshold, the pressure control algorithm has been developed. Therefore, using the proposed pressure control method, it has no particular ulcer occurred theoretically.

Callus was derived from the seedlings of Agastache rugosa(Labiatae). The growth rate of callus and the production of essential oil were studied with the variation of culturing conditions. 2, 4-D 2ppm in the medium was more effective for the production of essential oil than NAA 2ppm. The growth rate of callus and the production of essential oil were inhibited by the illumination of the light. The essential oils from Agastache rugosa and the callus cultivated on the medium containing 2, 4-D 2 ppm and kinetin 0.2 ppm were analysed by TLC, gas chromatography and mass spectrometry. These two oils showed different compositions. The main component of the plant oil, methyl chavicol was not contained in the callus oil.

The regulations for costume were set to improve people's moral fiber and cultural standards. In the 17th and 18th century, the main aim of this regulation was to prohibit luxury. But being the turning point to a modem state, with breaking social status and development of commerce, industry, and the mind of imitation, regulation for luxury wasn't enforced, but rather it brought many revolutionary changes in costume. Restraining human impulse to express beauty was no longer subject to regulation. Therefore, people started to recognize the human figure with shorter Jegory(저고리) and strengthened ceremonial capacity by broadening po's(포) sleeves. The silk fabrics were the most popular fabric during this era, special patterns were added for decoration and also for blessings. Complementary colors were used for contrast on the collar (깃), cuffs (끝동), Gyotrnagi (곁마기), and sash (고름). This color composition gave a younger and more active look. And with red stripes on the sleeves, it emphasized the beauty of the color arrangements as well as providing protection from the devil.

The most distinctive feature of the costumes of the Arctic regions from Alaska to Siberia centering around the Bering Sea connecting Asia to North America, is that each tribe makes clothes adequate to the climate and their lifestyles with animal hides obtained from hunting in their habitation. Furs or fish skins, the main materials for clothing, are characteristically cut into many pieces, and thus piece-joining patchwork is used to make or decorate garments. Patchwork is the technique that can create new designs with 3-dimensional and various combinations by modifying the simple materials, and also has the advantage of fitting the body without a certain cut line. Therefore, the patchwork found in the Arctic costumes may be developed from folk costume designs with limited materials like fur into new ones for modern or future costumes.

Seafarers are one of the main engines driving economic growth in the maritime sector. The International Maritime (IMO) Organization estimated that there were approximately 1.5 million seafarers around the world engaged in international trade in 2012. Data have shown that human casualties in maritime accidents around Japan have shown an increasing trend over the last ten years. One cause is human error, which is inseparable from the human element that influences mariner's decisions and actions. The Personal Identification (PIN) Safe method is one way to systematically identify substandard and unsafe actions by considering the error taxonomies associated with various scenarios for a maritime system. The results are based on analysis of the role of the human element in commonly reported unsafe actions when interacting with equipment and other systems. Furthermore, patterns of influencing shaping factors were observed on the basis of data processing; the aim of this study was to promote safety culture and provide an opportunity to improve safety at sea.

Tea is an aqueous infusion of dried leaves of the plant Camellia sinensis L. and is the second most widely consumed beverage around the world after water. Aroma compounds of tea differ largely depending on the manufacturing process, even from the same categories of different origins. The flavor of tea can be divided into two categories: taste (non-volatile compounds) and aroma (volatile compounds). In the present study, we review the formation mechanism of main aromas generated from carotenoids, lipids, glycosides as precursors, and Maillard reaction during the tea manufacturing process, with biological and chemical mechanisms.
