In this study, for the purpose of correct viewing on the image of Africa and understanding of modem fashion, African image and art, the general characteristics of African costume, the background of fashion subjecting African image, and the trend according to ages were examined based on theoretical background. Then the researcher drew African image by analyzing the works in four 2005 S/S major fashion collections to designers and design factors. The ten voted designers' and brands' works in 2005 S/S collections had four concepts of African image; 'Wild Erotic', 'Abstract Primitive', 'Natural Elegant' and 'Sporty Romantic'. The viewpoint of modem fashion on African image from the aspect of design, designer and fashion trend can be examined as below. First, African costume, which was religious and ceremonial, appeared to emphasize its esthetic side with decorative details in modem fashion design and designers competed to choose a method to harmonize tradition and modem style and by adopting these from occult to decorative meaning, Second, fashion designers presented city unpolished beauty of modem women to a special style and made african image to be recognized as a code of fashion culture by integrating it with modem people's mind to go back to the past and admiration for the purity of nature. Third, thanks to the instinctive vitality hidden in the primitive life, inspiration for creative design that is found in the esthetic mind of the Indians, foreign taste emphasizing ethnic trend, and admiration to naturalism due to the increase of concern over ecology, 'African image' led the beginning of 21C trend by being settled as a in fashion trend.

$CO_2$ 20세기 초 천연 냉매 $CO_2$는 광범위하게 사용되었지만 프레온계 냉매의 출현으로 1940년경부터 $CO_2$냉매는 사용이 제한되었다. 그러나 반 세기 동안 사라졌던 $CO_2$냉매는 1980년 후반에 노르웨이 과학 기술대학 (NTNU)과 북구 최대 민간연구소 (SINTEF)의 Lorentzen 교수에 의해 $CO_2$천연 냉매 사용을 재고하게 되었다. 프레온계 냉매의 환경적 논쟁이 쟁점이 되면서 천연 냉매 사용을 재고하게 되었다. 특히 비가연성과 비유독성으로 인한 $CO_2$냉매가 주목을 받고 있다. 초월임계 사이클레서의 고압 제어에 대한 새로운 개념은 Lorentzen 교수와 동료 연구원에 의해서 특허로 제안되었다. 이에 대한 상업적 권리를 Norsk Hydro사는 1990년에 얻었고,1990년대 초반에 NTNU/SINTEF의 공동 연구개발 프로그램을 통해 기술 경쟁력과 실현 가능성이 검증되었다. 현재 연구소에서는 최초로 초월임계 $CO_2$사이클을 이용한 상업용 온수 열펌프 시스템, 2003년 시작할 연료전지 전기 자동차에 대한 연구를 수행하고 있다. NTNU/SINTEF에서 개발된 $CO_2$기술은 Hydro-SINTEF 공동 벤처 기업인 Shecco기술회사를 통해 제조업자에게 허가된다. 본 고에서는 NTNU/SINTEF에서 수행하였거나 수 중인 과제들을 중심으로 유럽의 $CO_2$시스템의 결과와 주요 개발 범위를 정리하였으며, 특히 작동유체로서의 $CO_2$냉매의 특징을 간단히 설명하고, 온 수 열 펌프, 자동차용 공조기 및 열 펌프, 상업 냉동기 등이 기술되었다. 그 외 압축기 위주의 요소기술 개발에 관한 내용도 기술되었고, 차세대 기술 경향과 전망에 대해서도 제시되었다. 제시되었다.성균 350$\times$$10^4$ CFU균, 방선균 434$\times$$10^4$ CFU균, 진균 676$\times$$10^4$ CFU균으로 진균의 개체수가 비교적 높게 나타났으며, 비산불지역에서는 호기성균 328$\times$$10^4$ CFU균, 방선균 319$\times$$10^4$ CFU균, 진균 461$\times$$10^4$ CFU균으로 진균의 개체수가 높게 나타났다. 토양미생물은 호기성균, 방선균, 진균 모두 비산불지역 보다 산불지역에서 많이 나타났다. 본 조사지역에서 호기성균은 활엽수림보다 침엽수림에서 많게 나타났으며, 방선균과 진균은 침엽수림보다 활엽수림에서 많이 나타났다.효과와 이를 이용한 자기냉동의 방법 그리고 최근에 이루어진 새로운 진전에 대해 소개하고 공기조화 및 냉동분야에의 적용 가능성을 전망해 보고자 한다.및 도입 등 선주들에게 다양한 선박건조자금을 제공하여 내수기반 확충에도 노력해야 할 것 이다.있었다., 인삼이 성장될 때 부분적인 영양상태의 불충분이나 기후 등에 따른 영향을 받을 수 있기 때문에 앞으로 이에 대한 많은 연구가 이루어져야할 것으로 판단된다.태에도 불구하고 [-wh]의미의 겹의문사는 병렬적 관계의 합성어가 아니라 내부구조를 지니지 않은 단순한 단어(minimal $X^{0}$ elements)로 가정한다. 즉, [+wh] 의미의 겹의문사는 동일한 구성요 소를 지닌 병렬적 합성어([$[W1]_{XO-}$ $[W1]_{XO}$ ]$_{XO}$)로 그리고 [-wh] 의미의 겹의문사는 중복된 발은을 지닌 한 단어로 ([W]$_{XO}$ )

Although the number of registered cars in South Korea is above 21million and one family has about 1.07 cars, there is no national standard for automobile reference fuel in South Korea. Reference fuel is the fuel used for certificating vehicle performance, emissions and fuel economy. Now, domestic market fuels are used as reference fuel. However, the quality of domestic market fuel is constantly changing by seasonal and fuel manufacturers. It may effect vehicle performance, emissions and fuel efficiency test result. On this study, market fuel quality was monitored and reference fuel standard(draft) was set by reflecting market fuel monitoring result. Reference fuel standard(draft) was applied to GDI and MPI engine. As a result, the difference of fuel economy between fuels meeting the reference fuel standards(draft) was reduced to 1.1% while the difference of fuel economy between market fuels was 3.8%.

Sinjungsin Mask Play, one of Ttangseolbeop, is related to Seongjusin's life story. Sinjungsin Mask Play is a reconstruction of the story of the folk gods Seongjusin met while returning home. Seongjusin's life story proceeds in the form of Mask Play, and the monk who leads the sermon plays narration and main roles. Many believers play various roles and musicians. Sinjungsin Mask Play introduces many folk beliefs, sounds for intrigue, and talks. Sinjungsin Mask Play uses the same method of enumeration and repetition as the existing Mask Play. The repetition of a sentence or phrase plays a role in foreseeing the meaning of the context or foretelling the development of the plot to the audience. This repetition is intended to emphasize the situation of the scene and to create rhythm. Since Mask Play was exclusively for the common people, Mask Play actors use the repeating method commonly used in folk songs to form lines. This gives the audience a familiarity, effectively communicating the lines and responding to their tastes. Sinjungsin Mask Play borrowed people's way of playing for the public's mission. It inherits the dramatic forms of traditional traditional plays such as repetition of words or sentences or phrases, codification of words or sentences, borrowing of existing songs, and formal expression units. In addition, through repeated performances, believers can easily and easily learn and understand. This is the dramatic form and characteristics of Sinjungsin Mask Play. Sinjungsin Mask Play was handed down from Faith Communities and was used as a means of folk cultivation to spread illegality. Buddhism externalizes the process of accepting folk beliefs through Mask Play, and in the case of Shinto who participated directly or indirectly, they naturally acquire the belief system of Hwaeom Kyung through play. Sinjungsin Mask Play, one of Ttangseolbeop, can be said to have great value as an ICH, as well as popularization and mission.

The aim of this paper was to suggest a national R&D performance measurement index from a new perspective. Government is trying to transit the R&D paradigm from 'catch-up' into 'lead- forward'. The problem of the existing performance evaluation was first identified, and the performance evaluation method of domestic & overseas research center & government was then reviewed. In particular, this study first referred to the creation & innovation indices, and focused on the national innovation and R&D ecosystem. Next, D'Aveni's Hypercompetition theory was applied to suggest a new performance measurement index, and AHP analysis interviewed from the domestic R&D performance evaluation experts was performed. This study contributes to the new national R&D performance index for the creative economy.

Modern vehicles are evolving from manual to automatic driving. As the ratio of electrical equipment and software increases inside the vehicle, vehicles that support autonomous driving are becoming another open computer system that can communicate with the outside. The safety of the vehicle means the safety of both the passenger and the non-passenger. It is not clear whether the safety problem of ultimate autonomous vehicles can be solved by the current solution of computer systems related to fault tolerance and security. Autonomous vehicles should not be dangerous to people after they are released to the market, so it is necessary to proactively diagnose all the risks that can be predicted with current technology. This paper examines the current developments of autonomous vehicles and analyzes their dangers that threaten driving safety, as well as their countermeasures.
