This study was carried out to develop a miller to produce white embryo rice with functional nutrients by improving the conventional vertical miller. The effects of rice moisture content and the shaft revolution speed of the miller on germ(embryo) adherence rate, whiteness, broken rice rate, and cracked rice rate were investigated. Also, the effect of the mesh size of emery stones on the germ adherence rate was investigated. The vertical prototype miller was improved with the increasement of about 42% in producing white embryo rice at proper conditions(shaft revolution speed of 900 rpm, emery stones of mesh ＃50, processing capacity of 2.3t/h, zero outlet resistance, rice moisture content of 16.2%). The results were as follows: 1. The germ adherence rate of white rice was significantly influenced by the moisture content of brown rice. The germ adherence rate of white rice decreased rapidly with the increase of the moisture content of brown rice. When brown rice with moisture content of 13.2%, 14.5%, 15.2%, 15.4% was milled by the prototype with emery stones of mesh ＃35 and shaft speed of 900(1,100) rpm, rpm adherence rate of milled rice was 76.2%(70%), 69.2%(66%), 45.9(38%), 13.0(9%), respectively. 2. The whiteness of white rice milled by the prototype with emery stones of mesh ＃35 and shaft speed of 1,100(900)rpm increased from 27(23) to about 40, respectively, as the moisture content of brown rice increased from 13.2% to 17.2%. 3. The rate of broken rice of white rice milled at 900rpm decreased by 0.6∼1.0% compared with that at 1,100rpm when the moisture content of brown rice was less than 15.2%. 4. The germ adherence rate was increased by 10.3% and 11.0%, respectively when brown rice with moisture content of 16.2% and 15.5% was milled by the prototype miller with shaft speed of 900rpm and emery stones of mesh ＃50 instead of mesh ＃35. 5. Considering the germ adherence rate, broken rice rate, and whiteness of milled rice, the proper milling conditions of the prototype miller for producing embryo rice were the moisture content of about 15%, the processing capacity of 2.3t/h and minimum outlet resistance of 0Nㆍm with shaft speed of 900rpm and emery stones of mesh ＃50.

Yangbanxi("model plays") symbolize the Cultural Revolution(1966~1976) in China. The Eight Model Revolutionary Works include five Chinese Modern Peking Operas, namely, Taking Tiger Mountain by Strategy(智取威虎山), Harbor(海港), Shaijabang(沙家浜), The Red Lantern(紅燈記), and Raid on the White Tiger Regiment ; (奇襲白虎團), ballets such as The Red Detachment of Women(紅色娘子軍) and The White-Haired Girl(白毛女) ; and a symphony: Shajiabang(沙家浜). On April 24, 1967, Chinese leaders, including Mao Zedong, saw a performance of The White-Haired Girl. Yanbanxi was performed in Beijing between May 24 and June 15 the same year. The Red Lantern was designated as a work for the proletarian classes by Jiang Qing(Mao Zedong's third wife and the most influential woman in China) and spread nationwide. It was also made into a film to be enjoyed by many people. The modern Chinese operas went a long way in their creation of visual images of revolutionary heroes. The Red Lantern, in particular, came to be regarded as the most representative revolutionary opera. In the course of such a process, Jiang Qing used Yangbanxi as a political tool for compelling the people to worship and pledge their allegiance to Mao in an effort to turn the Cultural Revolution into a class struggle on behalf of her husband. During the Cultural Revolution period, artists were made to associate with workers, farmers and soldiers based on the idea of advocating revolutionary arts for the proletarian classes. The characters in The Rend Lantern were portrayed as heroes from the proletarian classes according to the demands of the era. Chinese leaders set forth the principles of artistic expression, stressing three important factors: politics, heroes, and heroic acts, which were to be applied to all the visual arts, including Yangbanxi. This paper attempts to present a new view of fine arts during the Cultural Revolution in China by focusing on the productive significance of a leading style of a specific era in the past. To that end, this paper sheds light on products made in conformance with political instructions, stressing the importance of revolutionary heroes in The Red Lantern.

The purpose of this study was to analyze the signification system between color and clothes systematically in black and white clothes. For this purpose, after examining the images of black and white clothes, we selected 55 clothes that represented as black and white and analyzed their meanings and the sources using semiotic framework, based on the work of Saussure and Barthes. The results as follows: First, the meaning in black and white clothes was generated from original color image. White clothes of religious person like Virgin Mary, Angel expressed pure and sacred color image. And black clothes like funeral dress expressed grief and death. Next, the meaning of black and white clothes was regenerated into modern color image by new environment. After industrial revolution, black was considered as a traditional men's fashion color. With diverse leisure activities, white sports wear appeared as active and clean image. Finally the source of the meaning of the clothes was the designer or the wearer. A little black dress by Chanel who was interested in simplicity and function represents an ideal of simple and sexy object. The situation is complicated by the fact that these three kinds of explanation may be found singly or mixed together.

Abrasive wear characteristics of high Cr white cast iron-based hardfacing were investigated using the rubber wheel abrasion wear test method according with the ASTM G65-85. Mild steel was also tested for comparison with high Cr cast iron hardfacing. Wear experiments, where the applied force, wheel revolution rate and abrasive powder feed rate were selected as test valuables, were planned and analyzed by response surface method to evaluate wear statistically and quantitatively. Weight loss of high Cr cast iron hardfacing was mostly affected by the applied force and wheel revolution rate, and little by the powder feed rate. Weight loss of mild steel was greatly affected by the wheel revolution rate and powder feed rate, and slowly and steadily increased with the applied force. Abrasive wear mechanism of high Cr cast iron and mild steel was discussed in the light of the wear test results.

With the recent development of the 4th Industrial Revolution, efforts have been made to carry out communication in a smart factory, farm, etc. at low cost and reliably. Methods for utilizing empty frequencies using TVWS(TV White Space) have been studied which can be used locally within 30 km. However, there have not been many studies on Path-Loss model considering Korean environment. In this paper, the Path-Loss model is divided into LOS (Line Of Sight) and NLOS (None LOS). In case of LOS model, we checked the difference between Free space model, Friis model, 2-ray model and Hata model with measured data. In the case of NLOS model, we checked the difference between Lee Model, ITU-R526-3 Model with measured data. In order to overcome the difference in Korean environment, we derived a model that can be applied in LOS and NLOS and prove its usefulness through performance evaluation through simulation.

Dairy development in India has emerged as one of the modern India's most successful development programmes. India's White Revolution, which has quietly swept the country during the past few decades, deserves attention equal to that given to the better known Green Revolution. India has become the largest milk producer in the world. From being a major importer of dairy products in the 1950s, India has now become an exporter. The strength of lndian dairy sector lies in the fact that despite of limited investment, it has shown consistent and sustainable growth. Presently India ranks first in the World milk production with 88.02 million tones (2002 03) with an annual growth rate of 4.2 per cent. Planning Commission estimates that by the end of Xth Plan, milk production may touch 100 million tones.

Agricultural extension services in Korea began in 1956, and led self sufficiency of rice through the 'Green Revolution' in 1970's, and a year around supply of green vegetables through the 'White/Vinyl Revolution' in 1980s. The developmental stages of agricultural extension services in Korea, in terms of major purposes, observed by the researcher were as follows; 1) Stage of production guidance when increase in production was directly related to increased income of farmers, 2) Stage of management guidance, when agricultural extension were not only concerned in increasing production, but also in management and marketing, and 3) Stage of improved welfare, when extension services put more emphasis on welfare of farmers in terms of quality of life, as well as increased production, management and marketing. Since late 1980s, farmers in Korea realized the fact that increased production may not lead to increased income. because of this, farmers also wanted improvement of management and marketing. Extension changed the identified needs of farmers to new knowledge, information, and technology in their farm business operation including management and marketing. Loosened cooperations among the central, provincial and local levels after localization of extension services since January 1997 should be strengthened. Provincial level monitoring and supervising should be enhanced for more effective agricultural extension services to meet the changing needs of farmers in the future.

The age of Queen Victoria, so called nearly 64 years from 1837 to 1901 that Queen Victoria was on the throne. It was the time that ceramicwares and silverwares were mass-produced thanks to the Industrial Revolution and then diverse directions of dining space could be possible in middle class. At the same time, it was the time that the production of bone china, which is main current in modem times, became established, ironstone china began to be developed, and white ceramic wares were accomplished. In addition, factors for the direction of dining space were mass-produced and Gothic style, Classic style, Majolica style, Renaissance, and Neo-rococo style had come back into fashion. Therefore, diverse designs coexisted and had great effect on dining space in this times. This study purposed to establish the decoration theory of dining space following historic flow through researching the designs and the direct factors for dining space in the age of Queen Victoria.

This paper focuses on "The Story of $Bras-Coup{\acute{e}}$" in George Washington Cable's The Grandissimes (1880), a story to and around which Cable claimed the larger work was built. It tells of an African candio sold into slavery who, to the dismay of his white purchasers, refuses to work, strikes his master, and runs away to lead a life of a fugitive in the swamps. He is finally captured, whipped, and maimed, but not before he casts a powerful voodoo curse at his master and his plantation. He dies a heroic death, with the last words that he goes "To--Africa." Cable once said that he "meant The Grandissimes as truly a political work as it ever has been called." It is a political work in that $Bras-Coup{\acute{e}}^{\prime}s$ personal rebellion is associated with much-feared slave revolts, especially the black revolution in San Domingue/Haiti. There is also $Honor{\acute{e}}$ f.m.c. (free man of color), one of the narrators of "The Story of $Bras-Coup{\acute{e}}$" and a stand-in for the Freedmen in the postbellum United States, who nurses his own insurrectionary flame. Through these figures Cable makes a "terrible suggestion" that a black revolution is on the horizon unless whites would not mend their ways soon.
