Watercolour painting was introduced to China over a hundred years ago, and in the last two decades, it has developed rapidly, presenting a situation of diversified development. While Western-style watercolour painting has been adopted by Chinese painters, they have also expanded on it with their own aesthetic awareness and cognitive styles. As a result, Chinese watercolour painting has developed a set of expressive techniques that highlight the cultural characteristics of the nation in terms of aesthetics, concepts and techniques, resulting in a painting style with a distinctive national personality at present. Although Chinese watercolour painting has taken on a variety of styles with the intervention of modern and contemporary art, realistic watercolour painting is still the mainstream. However, there are obvious differences between the "realism" of Chinese watercolour painting and the "realism" of Western watercolour painting in terms of expression. The most distinctive feature is the "imagery" language of expression, which is closely linked to the cultural heritage of Chinese tradition and is of great value for research. I interpret the aesthetics, composition, colour and brushwork of Chinese realistic watercolour painting from the perspective of traditional Chinese aesthetics in order to deepen the understanding of Chinese realistic watercolour painting and to provide a reference for the further development of the art of Chinese realistic watercolour painting.

Recently, Genetic Algorithm(GA), which is a stochastic direct search strategy that mimics the process of genetic evolution, is widely adapted into a search procedure for structural optimization. Contrast to traditional optimal design techniques which use design sensitivity analysis results, GA is very simple in their algorithms and there is no need of continuity of functions(or functionals) any more in GA. So, they can be easily applicable to wide area of design optimization problems. Also, owing to multi-point search procedure, they have higher porbability of convergence to global optimum compared to traditional techniques which take one-point search method. The methods consist of three genetics opera- tions named selection, crossover and mutation. In this study, a method of finding the omtimum size and topology of drilling machine is proposed by using the GA, For rapid converge to optimum, elitist survival model,roulette wheel selection with limited candidates, and multi-point shuffle cross-over method are adapted. And pseudo object function, which is the combined form of object function and penalty function, is used to include constraints into fitness function. GA shows good results of weight reducing effect and convergency in optimal design of drilling machine.

Traditionally, Korean ink painting used paper as a background medium. This tradition has sought a new attempt to meet today's demands while its expressive techniques and mediums become more diverse. The attempt of Korean ink painting to explore new mediums could change both its structure and style when considering the significance of the medium in the work. These new attempts have encouraged a further study of 'Korean Traditional Paper'. Today, 'Korean Traditional Paper' is considered to be an object itself rather than just being a background. In other words, there is no implication of a separation between the medium 'Korean Traditional Paper' and the work. Instead, the medium itself becomes the work. Therefore, 'Korean Traditional Paper' is not only a 'background' that contains the artist's desire to express, but at the same time also an 'object'. This study focuses on the attributes of 'Korean Traditional Paper' as an object, examines how this is visually applied in contemporary Korean ink painting in the relation to 'Korean Beauty', and reviews the work of some artists that use Korean Traditional Paper. The use of Korean Traditional Paper as an object first began with the experimental techniques of Lee , Eung-Noh and Kwon, Young-Woo in the 1960s, Then it seemed to stop for a while in the 1970s and 1980s until there was a renewed interest in the material personality of Korean Traditional Paper with the birth of the 'Korean Traditional Paper Artists Association' in the 1990s. This interest increased and Korean Traditional Paper was earnestly adopted by artists like Yim, Hyo Lee, Ki-Sook Won, Moon-Ja and Choi, Moo-Young, who used the paper in Broussonetia, the previous fibered state of rice paper. Here, the expression of the object through the characteristics of Korean Traditional Paper is a visual experiment to discover Korea's traditional art mediums that were forgotten once, focusing on the manifestation of Korean Beauty through Korean Traditional Paper. In this respect, this attempt has a valuable meaning in its use with a contemporary visual sense , based on the Korean sense of beauty.

The present study collected and analyzed the Korean's folk-belief related to Koran traditional costume culture which are handed down from ancestor and are known to present Korean society as of 1990's. The purpose of the present study is to understand emotion and the view of Korean people, and to understand the social roles of the costumes in Koran traditional society more deeply and more comprehensively. The study was conducted by document analysis and interview. The results of the study are summerized as follows: Folk-belief related to spinning(gilssam), sericultural industry and weaving are mostly enduced from the hope for god quality of work and acquisition of good skill of weaving. There has been also a belief hat gilssam has a magic power to easy delivery and fecundity. Most Folk-belief of taboo related to clothing constraction proposed to people pay great care while they are sawing. Some ways of management of clothing has been related to the manners of which are associated with the differentiation between high and low level and predominance of men over women that was originated fro m confucianism. Socks(busun) and shoes are also considered to have magic power to prevent from exorcism and demon of ill health. This study suggests that folk-belief give us the wisdom a guideline and lessons for better life, high quality arts and techniques which are handed down from ancestors. Therefore, folk-beliefs having a great value, non-shaped treasures of traditional culture heritage should be collected as many as possible, recorded, and preserved.

Traditional pile-buildings in Southeast Asia has high utility. Their floors are lifted above the ground to stave off humidity in the house, increase the amenity and hygienic condition, fend off fierce animals or harmful animals like rat, and protect the house from being submerged in flood waters. Such traditional pile-buildings have Austronesian saddle-backed roof commonly, and are built through various techniques such as joining and mortising, without use of nails. The roof has a considerably large proportional appearance, and for this formal characteristics, the roof is symbolized as boat on occasions. The roof has dual structures or is lifted in some cases to facilitate the ventilation, and the wall is formed to maximize the ventilation. This housing types the hierarchy of foundation, housing space, and roof, which implies religious symbolism that human is above animal and God is above human. However, housing types in Southeast Asia have very different detailed form and culture, depending on the ethnic and religious characteristics. As explained above, this study examines the common aspects and diversity based on the form and culture of traditional housing of Southeast Asia and provides useful basic academic data.

During the traditional production process of yugwa, a Korean traditional oil-puffed snack, three bacterial isolates, 12, 37, and B1 from waxy rice slurry were characterized by using the molecular techniques, and the quality of the yugwa prepared by using three isolates was examined in relation to physical and sensory properties. Isolates 37 and B1 were identified as Lactobacillus sp. by 16S rDNA sequence analysis, while isolate 12 was as Bacillus amyloliquefaciens by gyrA sequence analysis. Waxy rice inoculated with isolate 12 demonstrated the lowest hardness and the highest peak and [mal viscosity. Yugwa prepared from isolate 12-inoculated waxy rice indicated the lowest hardness and the highest volume expansion, the key characteristics of yugwa. This result presents the possibility for the use of a starter in the commercial production of yugwa and other rice-based snacks.

Understanding the present condition of Oriental traditional medicine in different country is demanded for the Korean Traditional Medicine to prepare his orientation in future. Also it is not possible to separate the present condition of OTM from history of oriental medicine as a whole. This is valid for the introduction of TCM in the west. The first information have arrived in Europe by the terrestrial and maritime travelers accounts. The diplomatic way, with special reference to Jesuit fathers, has brought cultural and theoretical precise data. The physicians of East India Company and, later, of expeditionary forces, have supplied with practical data. Five periods follow one another: 1) Period when the source reached and are used in Europe. This first step is intimately involved with the use and comparison of similar factor between the two medical systems ; 2) "Discovery" and use of needles ; 3) latent period when techniques coming from acupuncture source were developed ; 4) "Chinese Acupuncture" correctly speaking ; 5) modern period or investigating period, when Eastern and Western people are trying to correlate data of traditional medicine with those of western science. In particular the actual situation from 2000.

Prohibitin (PHB), an evolutionarily-conserved protein, has been found to be over-expressed in gastric cancer and be closely related with tumor malignancy. In this study, to investigate the relationship between PHB expression and cell apoptosis in the BGC823 gastric cancer cell line, low and high expression PHB in BGC823 cells was accomplished using RNA interference technology and gene transfer techniques. Cell proliferation, cell cycling, apoptosis, Bax, Bcl-2 and Cyt.c protein expression and the activation of Caspase-3,9 were assessed after 48h. Over-expression of PHB gene in BGC823 cells resulted in slow cell growth, cell arrest in G2 phase, and an increased apoptosis ratio while the opposite was found for PHB under-expressing cells. In PHB over-expressing cells, the expression of Bax gene was increased, the expression of Bcl-2 was decreased, the activation level of Caspase-3, 9 was increased, but the activation level of Caspase-8 demonstrated no change. These results indicate that PHB induced apoptosis through the mitochondrial pathway.
