This study aimed to analyze the expression of Hybrid in Contemporary Hair Design that is one kind of total fashion. In this research, by background of the hybrid characteristics of the messes culture art, the hybrid characteristics of the hair design has been defined as characters which is the mixture of timeless spaces, styles, sexes, unsuitable elements and cultures. The results of analysis by the expression of the hybrid hair design after 2000 is like this. As the researching, the hybrid characteristics of the hair design by the mixture of unsuitable elements and styles have been presented the highest. The result of the frequency of the apparition in the hair design molding elements according to the expression of the hybrid hair design, the hybrid characteristics of the unsuitable elements and style has been presented ideological form and the artificial form was the highest. The case of the hybrid of the activated texture, the unsuitable elements, style and timeless space has been presented excellently one after another. In the color tone, the mixture of the style, the unsuitable elements and timeless space has been presented one by one. The case of the hybrid of the image, the unsuitable elements that is the highest the frequency of the apparition was presented the image of the avant-garde, the fantastic and humor one after another.

A study was carried out to investigate the nutritive value and utilization of hybrid sorghum and perennial grass species viz. setaria (Setaria anceps) and hybrid napier when intercropped with soybean by growing Jersey crossbred heifers. Fifteen growing crossbred heifers (Jersey${\times}$Red Sindhi) of between 7-10 months age and pre-trial average body weight of 49-50 kg were divided on the basis of weight in to three treatment groups viz. $T_1$-hybrid sorghum+soybean, $T_2$-setaria+soybean and $T_3$-hybrid napier+soybean in a completely randomized block design. Intercropped forages were harvested fresh, chaffed and mixed before they were offered to the heifers. Chemical composition of the herbage, dry matter intake (DMI), body weight gain and nutrient digestibility co-efficients were estimated. The herbage mixtures had crude protein (CP) content in the range of 11.87 to 13.86% and ether extract (EE) contents were 2.91 to 3.11%, respectively. The herbage mixtures were rich in minerals (ash). The gross energy (kcal/g DM) was higher in hybrid napier+soybean, while hybrid sorghum+soybean and setaria+soybean herbage mixtures had lower value for gross energy. The hybrid sorghum+soybean and setaria+soybean herbage mixtures had higher contents of NDF, ADF, cellulose, lignin and silica as compared to that of hybrid napier+soybean herbage mixture. The heifers fed hybrid napier+soybean herbage mixture had significantly (p<0.05) higher $DMI\;g/kg\;W^{0.75}$ ($97.41{\pm}4.34$) as compared to hybrid sorghum+soybean ($88.31{\pm}2.66$) and setaria+soybean ($79.29{\pm}1.06$) herbage mixtures. Nutrients digestibility, DCP percent, DCP intake and nitrogen balance were significantly (p<0.05) higher in the heifers fed on hybrid napier+soybean herbage mixture. There was a significant (p<0.05) difference among different herbage mixtures in TDN. The heifers on setaria+soybean herbage mixture had lower average body weight gain (g/day) than those on hybrid sorghum+soybean and hybrid napier+soybean herbage mixtures. Data obtained in this experiment demonstrated that herbage mixture of hybrid napier+soybean was better than hybrid sorghum+soybean and setaria+soybean herbage mixtures in the nutrition of growing heifers. It had highest nutritive value, better digestibility co-efficients which showed better growth rate and higher feed efficiency. In ranking, hybrid napier+soybean herbage mixture was better followed by hybrid sorghum+soybean and setaria+soybean in nutritive value in the parameters studied. For future wasteland development program in humid-sub tropics of Himachal Pradesh hybrid napier and its intercropping with soybean is recommended for general adoption because of its better adaptability and higher nutritive value.

본 연구에서는 two-phase model(이상 모델)을 활용하여, 고폭약(RDX) 입자가 고르게 분포되어 있는 에틸렌-공기 혼합물의 데토네이션 속도, 압력을 포함하는 데토네이션 특성을 확인하였다. 순수 가연성 기체 혼합물 내에 고폭약 입자를 분포시킬 경우, 고폭약의 화학 반응에 의한 열방출에 의해 순수 가연성 기체 혼합물의 데토네이션 보다 높은 압력 및 임펄스 증가를 발생시킬 수 있다. 본 연구에서 제안된 수치해석 접근법으로 계산한 결과를 검증하기 위하여, 이전에 수행된 실험 결과(RDX 입자의 함량에 따른 데토네이션 압력/속도)와 비교하였다.

공비점이 존재하거나 상대휘발도 차이가 적은 2성분 혼합물은 단일 증류탑으로 분리하기 어렵다. 이때 혼합물에서 분리가 어려운 영역을 투과증발막을 사용하여 분리하면 효율적인 공정을 설계할 수 있다. 본 연구에서는 물-유기용매 혼합물을 분리하기 위한 증류-투과증발막 혼성공정을 제시하고, 물-초산 혼합물과 물-에탄올 혼합물의 분리공정을 각각 모사하였다. 증류탑 상부 흐름이 친수성 막을 통과하여 물을 높은 순도로 분리하는 공정을 모사하였다. 실험과 문헌에서 얻은 친수성 막의 투과도를 토대로 막 모델을 만들어 막 면적을 계산하였다. 제시한 공정의 최적화를 위해, 목적함수를 연간 총 비용으로 정하고 주요 설계 변수들을 최적화 변수로 하여 최적화 문제를 구성하였다. 또한, 혼성공정의 각 최적화 변수의 변화에 따른 목적함수 값의 변화 추세를 나타내고 최적화 변수를 최적점에 가까운 값으로 쉽게 추측할 수 있는 방법을 제안하였다.

This study is about the features of hybridization of ethnic-cultural elements in Korean fashion magazines. Its purpose was to embody more creative and newer images in fashion by promoting better mutual understanding of foreign cultures and addressing the issues of fashion design from multicultural perspectives. In doing so, the present study conducted a literature review and analyzed a total of 130 photographic images with any hybrid ethic element from two Korean fashion magazines, Vogue Korea and Harper's Bazaar Korea, issued between 2005 and 2009. The analysis revealed that there were 66 images(50.8%) with a mixture of two different cultures and 64 images(49.2%) with a mixture of three or more different cultures. As seen from the results, the two categories had a similar number of cases. In regional terms, the use of two different cultural elements included a mixture of Asian and Western cultures in 32 images(24.6%), a mixture of Western and African, Middle Eastern or Latin American cultures in 23(17.7%), and a mixture of Western and Russian or European folk cultures in 11(8.5%). In the use of three or more different cultural/national elements, the present study found a mixture of Asian, African, Middle Eastern, Latin American and Western costume items in 20 photo images(15.4%), a mixture of African, Middle Eastern and Latin American elements plus Western costume items in 19 images( 14.6%), a mixture of all regional cultures in 13 photos(10%), and a mixture of Asian ethic cultures plus Western costume items in 12 cases(9.2%). The results of this analysis indicated that the hybridization of ethnic-culture elements in Korean fashion magazines consisted of diverse clothing and accessories from various ethnic groups. The expression of these multi-cultural hybrid images that consists background images and models from different cultures well-portrayed the multi-cultural elements based on total coordination and broke the stereotypical aspects of styling.

This paper proposes a numerical modeling approach to simulate the hybrid combustion phenomena. From the physical understandings of hybrid combustion, the computational domain was separated into three regions: the solid fuel, gas phase reactive flow, and the interface between solid and fluid. Moreover, for the accurate calculation, computational grids for these regions was generated at every time step considering the instantaneous moving interface which are governed by the balance equations using thermal pyrolysis. In the domain of reactive flow, by virtue of diffusion flame structure, turbulent combustion modeling was introduced using either mixture fraction approach or mean reaction rate approach.

Microwave (Hybrid) Heating (MHH) was used to oxidize and sinter Al-Al2O3 powder mixture. For 25 v/o Al specimen and 35 v/o Al specimen, the total processing to produce low-shrinkage reaction bonded alumina was carried out within 1 hour even though conventional furnace process took more than 10 hours. Compared with conventional fast firing process, MHH process increased more than 40% oxidation at the same temperature, and these high oxidation rates were thought to be caused by the surface ohmic current on Al particles.

Biphenyltetracarboximide-phenylene diamine polyimide/silica-titania ternary hybrid composites were Prepared by thermal imidization and sol-gel reaction. Fluorescence spectroscopic, scanning electron microscopy, and atomic force microscopy studies revealed that the addition of small amount of titania showed profound effects on the microstructure and photophysical behaviors of polyimide/silica hybrid composites, when the content of silica-titania mixture was small or when the ratio of silica to titania in the mixture was high.
