  • In this paper, the basic experiment, electrolytic cell design and basic manufacturing have been made to interpret the characteristics of Hydrogen-Oxygen-Gas-Generator. As for the detailed matters, the data research on basic technology on Hydrogen-Oxygen-Gas and analysis on characteristics of Hydrogen-Oxygen-Gas from basic experiment. Also the experiment of characteristics and comparative evaluation between constant current source using SCR converter from existing method and constant current source using new phase shift PWM control method converter. As results when it has injected constant DC current, we has compared Gas quantities by variable ripple frequencies using phase shift PWM control method converter. Therefore, in linear region, it has not different Gas quantities by constant DC current and by phase shift PWM control method converter. Also, it has increased Gas quantities wilder linear region when put ripple frequency at saturation region. Through, Gas quantities and input rower, it has acquired higher input power per Gas quantities at put pulse current. Therefore, when designing converter or inverter for electrolysis, which has ripple current.

  • The surrealism art form comes from the world of unconsciousness. Based on its expression of the world of imaginary, it boldly demonstrates the arrangement and the forms of contradicted objects and the development of collage, montage, and protage techniques in the works which had a big influence on the growth of the modern art. The ideology and the modeling characteristics shown in the surrealism had various expressive forms and meanings in the modern compound expression and it grew out of the former standarlized forms and brought diversity and individuality based on the sensibility of the new avant-garde art form and showed great potential as it presented harmony in the multiple forms of art. The purpose of the research was to analyze the influences that were put on the surrealistic fashion art works and the works of the representative designer, Jean Paul Gotie. The characteristics of Jean Paul Gotie's surrealistic fashion comes from destruction, sexual image, and the mixture of heterogeneous. It is evident that the surrealistic fashion went beyond certain groups of avant-gardists' salvation of the world and were put to practice use, reaching out to the ordinary consumers. This was resulted from the revolutionary movement called, "anti-mode van fashion" led by Gotie. The surrealistic style will be led by various techniques and trends and developed through new characteristics in multiculture merged with various fashion styles.

  • This study aimed to analyze the types and characteristics of space forms according to the composition of the stage and auditorium space along with the expression trends in the space of performing arts centers through the cases of modern performing arts centers in America. Today since the purposes of performance are multiple, a variety of stage types are applied to each performing arts center. They use various spaces and performances of multiple purposes by moving and transforming the stage and auditorium according to the kinds of performance as a variation of the arena stage. In today's performing arts centers, the sizes of the stage and auditorium can vary widely, and the performances of many different genres are put to multiple purposes. There appear complex performing arts centers that can plan performing spaces of diverse sizes and forms to fit the functions of a performance in a large building. Since they put on performances in a large space according to the characteristics of the kind of performance, the intentions and goals of the performance are well delivered to the audience.

  • Objectives: Examine the difference of Chosun acupuncture from the acupuncture in Myung, Chung Dynasty Method: This paper examines the acupuncture mentioned in the classic of Introduction to Medicine For this, the special traits of Introduction to Medicine acupuncture was analyzed. Secondly, the research on the contents of Introduction to Medicine acupuncture quoted in the classic of Essential Rhymes of Acupuncture and Moxibustion, Treasured Mirror of Eastern Medicine, and Experimental Prescriptions of Acupuncture and Moxibustion was carried out. Result: Introduction to Medicine put much importance on "method of acupuncture following the five circuits and six qi" (子午流注針法) and Song of Acupuncture and Moxibustion through comparing "eight methods of acupuncture following the five circuits and six qi" (子午八法) and "scattered needling method". The doctors in Chosun Dynasty, howevery, did not adopt this theory with their own standards on acupuncture. On the contrary, they put more importance on the inquiry of historical evidence on river point and extraordinary points. Conclusion: The acupuncture studies of Chosun Dynasty had already formed its own standards on the medical theories, and its direction to which it was headed was different from that of the Myung, and Chung Dynasty in China.

  • This research studies how a rain coat (兩衣) had developed in ancient China by searching through historic records. It can be said that people in ancient China wore two kinds of rain coats: straw coat and oiled-cloth coat (油衣). Straw coat was originally used in the Spring and Autumn and Warring States period. Then, people used natural grasses to make it. As the overall production had increased, various kinds of rain coats began to appear in Tang (唐) Dynasty, and the straw coat itself became elaborate. In Song (宋) and Yuan (元) Dynasty, the straw coat was used for the army, and when it came to be Ming (明) and Qing (淸) age, wearing it was considered a symbol of hermit. The straw coat shows the early form in the history of clothing, which was mostly put on by the poor. The material for straw coat was the grass which grows up in wet land area. People in the city and in the country had worn the straw coat for a long time. As foreign cultures were introduced, however, it disappeared first in cities and later in the country. The oiled-cloth coat was another of the kind. Its major material was water-proofed silk in the Qin(泰) and Han(漢) Dynasty. Also, it was a favorite of an emperor or aristocrats. Common people put on straw coat until the time the western rain coat was introduced and accepted in Qing Dynasty.

  • 고순도의 CHMI 입자를 제조하는 공정을 개발하기 위해서, CHMAIE로부터 CHMI를 합성하고 정제한 후 형상화하는 공정 전반에 대한 실험적 연구를 수행하였다. CHMI 합성에 있어서는 n-헵탄 환류 이미드화 반응이 톨루엔 put-out 이미드화 반응보다 CHMI의 평형 전화율이 높을 뿐 아니라, CHMI의 석출공정에도 유리한 것으로 나타났다. 합성된 CHMI를 n-헵탄으로 2회 세척하면 11.7%의 무게 감소율이 발생하지만, 99.7%의 고순도 CHMI를 얻을 수 있었다. CHMI 입자의 제조에서는 3 mm 나선형 노즐을 통하여 $1.5{\sim}2.0kg/cm^2$의 압력으로 CHMI 용융액을 토출시키면 가장 효과적으로 CHMI 입자를 제조할 수 있었다.

  • In this paper uses Kaname Akamatsu's 'Flying Geese' model to analyse Japan's role in East Asian integration. Japan made the first attempt to lead Asian countries before the Second World War. At that time, the Japanese Government embarked on a brutally expansionist policy the result of which was creation of the first gaggle of 'flying geese' under the name of the 'Greater East Asia Co-Prosperity Sphere.' During the 'flight' Japan was forcefully imposing its own ideals and values on the rest of the 'gaggle.' At the same time, the Japanese Government assumed hostile attitude toward Western countries. Japan's defeat in the Second World War signified the end of flight for the first 'flying geese' gaggle. After the war, Japan made another attempt at regional integration. This time it was done through establishing a production network in East Asia. Thus the second gaggle of 'flying geese' came into existence. During the flight of the 'second gaggle' of geese, Japan was fostering good ties with Western countries as well, especially the United States. However, some leaders of the 'second gaggle's' member-countries emboldened by their countries' economic success proclaimed that future belongs to Asia and put forward the 'Asian values' argument. The Asian economic crisis of 1997 interrupted the flight of the 'second gaggle' and effectively put an end to the 'Asian values' debate. It is interesting to note that some elements of the 'Asian values' argument resembled ultranationalist discourse that had been dominant in Japan before and during the Second World War. This paper compares historical patterns of East Asian regional integration and highlights future challenges for Japan's Asia policy.
