This study aims to explore the characteristics of translated picture books in South Korea and their cultural meanings over a five-decade period. This time can broadly be divided into three periods, being the Settlement Period (pre-1990), the Flourishing Years (1991-2000) and Globalization (post-2001). During the Settlement Period, picture books in South Korea were derived mainly from Japan and America and tended to be informational in nature or based on folk tales. These were translated into Korean to meet the public's curiosity for foreign cultures or for scientific information. The Flourishing Years were characterised by the availability of picture books on a wide variety on themes and forms from all over the world. In this period, the translation of books into Korean focused on a literal rendition of the meanings and sounds of names from the original text. There was also a proliferation of audiotapes, videos and TV programs based on famous picture books. In the current period of Globalization, Korean publishers, who have built confidence through studying foreign picture books over time, have increased efforts to produce their own picture books and export them abroad.

Wood carving has been extremely widely practiced, but survives much less well than the other main materials, being vulnerable to decay, insect damage, and fire. It therefore forms an important hidden element in the art history of many cultures. Even though wood is less durable than either steel or stone, it has been used for a long time due to its usefulness. Wood has a lot of benefits. So people have used wood for materials in houses, trains, cars, bridges, and simple utilities in their ways according to their own religions, climates, and environment they are living in. Nowadays, there are wood products that are made up for its weaknesses and this has made wood be used in variety fields. Moreover, wood has been widely selected materials for sculptures, interior, and also for architecture thanks to its colors and textures. Wood has helped our life more abundant and beautiful.

This study was aimed at knowing the magnitude of year variation in rice heading dates under the different seasonal cultures, and to estimate the heading date in advance. Using six rice varieties such as Kwansan, Suwon＃82, Suwon ＃144, Norin＃17, Yukoo＃132 and Paltal, the early, ordinary and late seasonal cultures had been carried out at Paddy Crop Division, Crop Experiment Station at Suwon for the six-year period 1959 to 1964. In addition the data of the standard rice cultures at the Provincial Offices of Rural Development for the 12-year period 1953 to 1954, were analyzed for the purpose of clarifying a relationship between variation of rice heading dates and some of meteorological data related to the locations and years. The results of this study are as follows: 1. Year variation of rice heading dates was as high as 14 to 21 days in the early seasonal culture and 7 to 14 days in the ordinary seasonal culture, while as low as one to seven days in the late seasonal culture which was the lowest among three cultures. The magnitude of variation depended greatly on variety, cultural season and location. 2. It was found out that there was a close negative correlation between the accumulated average air temperature for 40 days from 31 days after seeding and number of days to heading in the early seasonal culture. Accordingly, it was considered possible to predict the rice heading date through calculation of the accumulated average air temperature for the above period and then the linear regression(Y=a+bx). On the other hand, an estimation of the heading date in the late seasonal culture requires for the further studies. In the ordinary seasonal culture, no significant correlation between the accumulated average air temperature and number of days to heading was obtained in the six-year experiments conducted at Suwon. There was a varietal difference in relationship between the accumulated average air temperature for 70 days from seeding and number of days to heading in the standard cultures at the provincial offices of rural development. Some of varieties showed a significant correlation between two factors while the others didn't show any significant correlation. However, there was no regional difference in this relationship.

In the past decade, considerable progress has been made in developing the appropriate biotechnology for microalgal mass cultivation aimed at establishing a new agro-industry. This review points out the main biological constraints affecting algal biotechnology outdoors and the requirements for making this biotechnology economically viable. One of them is the availability of a wide variety of algal species and improved strains that favorably respond to varying environmental conditions existing outdoors. It is thus just a matter of time and effort before a new methodology like genetic engineering can and will be applied in this field as well. The study of stress physiology and adaptation of microalgae has also an important application in further development of the biotechnology for mass culturing of microalgae. In outdoor cultures, cells are exposed to severe changes in light and temperature much faster than the time scale re-quired for the cells to acclimate. A better understanding of those parameters and the ability to rapidly monitor those conditions will provide the growers with a better knowledge on how to optimize growth and productivity. Induction of accumulation of high value products is associated with stress conditions. Understanding the physiological response may help in providing a better production system for the desired product and, at a later stage, give an insight of the potential for genetic modification of desired strains. The potential use of microalgae as part of a biological system for bioremediation/detoxification and wastewater treatment is also associated with growing the cells under stress conditions. Important developments in monitoring and feedback control of the culture behavior through application of on-line chlorophyll fluorescence technique are in progress. Understanding the process associated with those unique environmental conditions may help in choosing the right culture conditions as well as selecting strains in order to improve the efficiency of the biological process.

Rhamnose-rich (RROP-s) and fucose-rich (FROP-s) oligo-and polysaccharides were prepared and extensively characterised by physical and chemical procedures [1,2] and compared to L-fucose. Their biological properties were then studied on human skin fibroblast cell cultures, human skin explant cultures and on hairless rat skin, using a variety of cell-biological, biochemical and computerised morphometrical procedures. Among the most important properties we could establish, the following are of particular interest for the tretment and prevention of age-dependent modifications of human skin (loss of skin-tissue, cells and matrix, wrinkle formation and others) : stimulation of cell proliferation (by $^3$[H]-thymidine incorporation and the MTT test), scavenging of reactive oxygen species (ROS) using several different procedures, and protease (MMP-2 and MMP-9) down-regulation. A topical preparation, using RROP-s and FROP-s, and/or L-fucose, was shown to increase cell proliferation, dermal matrix synthesis, efficient scavenging of ROS-s and to increase also the thickness of dermal tissue when applied for 4 weeks on hairless rat skin, accompanied by the densification of collagen bundles as well as by an increase of elastin synthesis. Using fluorescent labeled FROPs, it could be shown that these oligosaccharides react with cell-membrane receptors and especially with the elastin-laminin-receptor and the fucose-mannose receptor, but they penetrate also in the cell nucleus, suggesting the possibility of a direct action on the regulation of gene expression. When applied to the human skin of a team of voluntary women encompassing all age-groups, the efficiency of FROP-containing preparation could be confirmed using indentometry and computerised evaluation of skin micro-relief, as well as evaluation of periorbital wrinkles. It appears therefore that these preparations correspond to all the requirements of active anti-aging principles.

The rice variety, Kwanok, was reared in the water and land beds and transplanted to the reclaimed soil area, having an average salt concentration of 0.39%. Two levels of the moderate and late season cultures with 4 treatments were used. The K and Si contents of the stem part of land bed seedlings were somewhat smaller, but total carbohydrate remarkably larger, the C/N ratio was accordingly greater than water bed seedlings. The rooting ability of land bed seedlings was vigorous markedly in culture solutions, to which added various concentrations of NaCl, The rooting ability of each seedling water not much declined in theculturing solution of up to 9.4mmhos/cm, (0.6%) of salt concentration, but it was drastically declined in the salt concentration over that. It seemed that the critical salt concentration for the rooting rice plant. The land bed seedlings in each salty condition markedly decreased compared with the water bed seeldings in transpiration rate and it showed a stronger drought resistance and contained a large amount of chlorophyll at transplanting stage, and also showed higher stability of chlorophyll at rooting stage in the salt treatment. The number of panicles, panicle weight, number of grains per panicle and ratio of matured grains of the rice plant grown by the land bed seedlings were much greater and 1,000 grain weight was less than from water bed seedlings. The cultural practices with the land bed seedlings increased the rough rice yields by 15% and 11%, respectively, compared with the yields of the moderate and late season cultures by water bed seedlings.

A variety of traditional costumes have been developed in Asia due to different natural and cultural environments and they are still worn by people in many areas. Traditional costumes in Asia have been formed under the influence of various ideologies, as well as technology and social structure. Three Asian religions(Buddhism, Hinduism and Islam), which have undeniably strong influence on traditional Asian cultures, have great effects on the styles of traditional costume in each region of Asia. The purpose of this study is to compare the characteristics and aesthetic values of traditional Asian costumes. To do this, the author used images of traditional costumes, which were taken in person by the author, in each region of Asia as reference. Unlike the traditional costumes in the West, which expose the body shape, traditional Asian costumes have nonstructural features in construction, form and wearing rules. They are also decorated with religious symbols and other ornaments, which is different from functional and non-decorative modern clothes. Each traditional Asian costume has unique characteristics. The costume under the influence of Buddhism shows the beauty of concealment that features trans-spatiality and abundant silhouette. On the other hand, the Hindu costume shows the beauty of symbolization represented by very colorful and complex ornaments, while costume in the Islam regions shows the beauty of restraint with clothes that wrap up the body in accordance with its strict religious discipline. Asian religions also represent philosophy, culture as well as an ethnic group. They have influenced entire Asian cultures including the arts, aesthetics and social structure and decided the style of costumes.

Insect cell cultures have become important tools in the production of biological substances for use in a variety of research, human and veterinary medicine, and pest control applications. These applications often require the introduction of foreign DNA into the cells and have generally used methods originally developed for use with human and other mammalian cell cultures. While these methods can be successfully employed, they are often less efficient with insect cells and frequently involve complex procedures or require specialized equipment. Even when they do work, they may require substantial modification because of differences in the culture medium or growth patterns of insect cells. In this study, We have optimized transfection conditions of Sf9 cell line using insect expression vector pIZT/V5-His which expresses green fluorescent protein effectively. Human stem cell factor (hSCF) is a glycoprotein that plays a key role in hematopoiesis acting both as a positive and negative regulator, often in synergy with other cytokines. It also plays a key role in mast cell development, gametogenesis, and melanogenesis. It can exist in membrane-bound form and in proteolytically released soluble form. As determined by an enzyme-linked immunosorbent assay performed, hSCF level in supernatant averaged 995ng/ml. The human hSCF was partially purified by immunoaffinity chromatography and analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting. The results show that the hSCF has N-linked carbohydrate and corresponds to the soluble form, at or about 223 amino acids in length. The findings suggest functional importance for soluble hSCF in cells.

Lactic acid bacteria (LAB) play an important role in dairy fermentations, notably as cheese starter cultures. During the cheese production and ripening period, various enzymes from milk, rennet, starter cultures, and non-starter LABs are involved in flavor formation pathways, including glycolysis, proteolysis, and lipolysis. Among these three pathways, starter LABs are particularly related to amino acid degradation, presumably as the origins of major flavor compounds. Therefore, we used several enzymes as major criteria for the selection of starter bacteria with flavor-forming ability. Lactococcus lactis subsp. lactis LDTM6802 and Lactococcus lactis subsp. cremoris LDTM6803, isolated from Korean raw milk and cucumber kimchi, were confirmed by using multiplex PCR and characterized as starter bacteria. The combinations of starter bacteria were validated in a miniature Gouda-type cheese model. The flavor compounds of the tested miniature cheeses were analyzed and profiled by using an electronic nose. Compared to commercial industrial cheese starters, selected starter bacteria showed lower pH, and more variety in their flavor profile. These results demonstrated that LDTM6802 and LDTM6803 as starter bacteria have potent starter properties with a characteristic flavor-forming ability in cheese.

Industrial design has been need to made a new tool for human with adaptable to situation the age. But, at early America, it is very difficult that role of design settle down and progress than these days. It is not to he easy newly born in industrial design because of rapidly changing the America situation with multi settlers, the Depression and world wars. There was various design change in short period. So we called the step modern 1920 and the streamlined 1930. The study is background of American design by variety cultures & creatures from 1920s to 1930s. Some of Korea design has affected of America cultures at duration of 6.25 war and now. This study has included early culture & industrial life, designer activity, and at the part of rear new invention, industrial design relate to architect, four leading designers Walter Dorwin league, Norman Bel Geddes, Henry Dreyfuss, Raymond Loewy. In present world situation, It is important in all aspect to understand that early process at America industrial design. Early American culture is constructed from the building block of the puritan ethic and is sheathed by liberal mercantilism, today is became one stir it into the common molting pot.
