비타민 E 150 IU, selenium yeast로 셀레늄 1.2 ppm에 비타민 E를 100, 150, 200 및 300 IU로 복합 첨가하였을 때 육계의 사료 섭취량, 증체량, 사료 요구율, 계육 품질 및 selenium 축적에 미치는 영향을 조사한 결과를 요약하면 다음과 같다. 1. $1{\sim}21$일의 증체량은 대조구와 비타민 E 150 IU 첨가구가 높았으며(P<0.05), 사료 섭취량은 비타민 E 150 IU 첨가구가 유기태 셀레늄 1.2 ppm에 비타민 E 150 IU와 200 IU를 복합 첨가한 구에 비하여 증가하였다(P<0.05). $21{\sim}35$일의 사료 섭취량은 대조구가 유기태 셀레늄 1.2 ppm에 비타민 E 200 IU를 복합 첨가한 구에 비하여 증가하였다(P<0.05). 그러나 시험 전기간의 사료 요구율은 대조구를 포함한 모든 처리구에서 차이가 없었다. 2. 가슴 근육의 셀레늄 함량은 대조구와 비타민 E 150 IU 첨가구에 비하여 유기태 셀레늄과 비타민 E를 복합 첨가함으로서 유의적으로 높게 나타났으며(P<0.05), 간조직의 셀레늄 함량 역시 대조구와 비타민 E 150 IU 첨가구에 비하여 유기태 셀레늄과 비타민 E를 복합 첨가함으로서 높게 나타났다(P<0.05). 3. 저장 기간별로 TBARS는 대조구와 비타민 E 150 IU 첨가구는 1일보다 3일차가 높게 나타났으나(P<0.05), 셀레늄 1.2 ppm에 비타민 E 100, 150, 200 및 300 IU 복합 첨가구는 1일과 3일간에서 차이가 없었으며, 3일차에는 대조구보다 비타민 E와 셀레늄 복합 첨가구가 낮게 나타났다(P<0.05). 이상의 결과를 종합하면, 육계 사료에 유기태 셀레늄 1.2 ppm에 비타민 E를 100, 150, 200 및 300 IU를 복합 첨가시 생산성에는 차이가 없으나 계육 내 selenium 함량과 저장성은 향상되었다.

The effects of organic Zn-L-selenomethionine (Zn-L-SeMet) at 0.3 ppm on carcass composition, meat characteristics, fatty acid composition, glutathione peroxidase activity, and ribonucleotide content were compared against the commercial inorganic sodium selenite (Na-Se) and the combination of the two, in commercial broilers. A total of 540 one day-old chicks were assigned at random to 3 dietary treatments : i) commercial inorganic selenium as control or T1, ii) a 1:1 ratio of inorganic and organic selenium as T2, and iii) organic selenium as T3. Carcass composition, meat characteristics, cholesterol content, fatty acid composition, and ribonucleotide content were generally unaffected by treatments. However, discrepancy were significantly observed in glutathione peroxidase activity (GSH-Px) and water holding capacity, with organic selenium showing higher glutathione peroxidase activity (p<0.01) and lower shrinkage loss (p<0.05), respectively. These findings could be explained by the contribution of organic selenium in bioavailability of GSH-Px. However, having conducted in a commercial close house system with sufficient amount of nutritional supplementation, the present study demonstrated little or no effects of organic Zn-L-SeMet on meat characteristics, fatty acid composition, and ribonucleotide content (flavor characteristic) in broiler chickens.

In this study, flowability of the mortar added with length change and combination of steel and inorganic fiber has been tested to evaluate the performance of fiber-reinforced mortar. The following results could be made as the conclusion. Early age flow of the mortar has been decreased when fibers added. Slump also decreased with the adding of fibers. For the air content, comparing with Plain, all the specimens with fibers showed higher air content than Plain., Addition of every kinds fibers showed the similar EIS test results.

Due to the increase in the usage of explosive materials and terrorism, the interest towards the superior explosion protective HPFRCC has risen. In existing research, the optimum ratio for solving the problematic problems such as the optimum fiber incorporation rate and the self-shrinkage crack of HPFRCC had been derived. However, there had been few or even no research upon how effective HPFRCC would perform protective explosion-proof in actual explosion. Therefore, this research compared the explosion-proof performance of HPFRCC according to fiber commination and mixing ratio. As a result, the combination of steel fiber and organic fiber showed excellent flow and strength, and it also improved the explosion resistance.

본 연구는 멀티미디어 객체 스트림 전송 프로토콜을 위한 QoS지원 기법과 관리에 관한 연구를 수행하였다. 자원관리자는 시스템 자원정보를 QoS관리자에게 제공한다. QoS 및 시스템 자원의 2차원 정보를 가진 QoS 관리자는 자원 관리자와 서로 같은 시간 영역으로 강력하게 유기적으로 결합되어 효과적인 QoS관리를 수행한다. 그러므로 연결 수락에 대한 빠른 판단이 가능하고, 성능 변동(performance fluctuation)들을 실시간으로 감지하고 대응할 수 있다.

To suggest the native plants combination for restoration of the dissected sloping area, the plant communities of thirty seven quadrats from five localities of mid-southern part of Korean peninsula were surveyed from 2007 to 2008. Their flora, vegetation structure, and dominant species based on the importance value were investigated. And the soil characters (pH, moisture content, water holding capacity, and organic matter) of each dominant species were analyzed. Also, germination tests were performed to check the stability of restored native plants using seed chips. As a result, 79 native plants were suggested for the dissected sloping area : 20 trees and subtrees for the upper layer, 18 shrubs and vines for the middle layer, and 41 herbs for the lower layer, taken together their flora, dominant species, vegetation structure, soil condition, germination test, flowering period.

The experiment fields consisted of five plots as follows; 2, 4, and $8\;tons{\cdot}ha^{-1}$ citrus skin in combination with starch sludge and pig manure mixing compost (CSSP), $4\;ton{\cdot}ha^{-1}$ fermented pig manure compost (FPMC) treated plot, and untreated control. Plant height and stem diameter were significantly increased by CSSP. Most of all, average tuber weight and tuber yield per plant were significantly increased in 4 and $8\;tons{\cdot}ha^{-1}$ CSSP plots compared to the other plots. Marketable tuber (>50 g fresh weight) yield were superior in order of 4 and $8\;tons{\cdot}ha^{-1}$ CSSP plot, $4\;tons{\cdot}ha^{-1}$ FPMC plot, and $2\;tons{\cdot}ha^{-1}$ CSSP plot.

Berlin Philharmonic Concert Hall is one of most prominent architecture of Hans Scharoun, which is known as the fine combination of the functionalism as an important factor in modern architecture and the hi-developed technology Moreover, the plan and spatial planning of the concert hall is famous for its evolutionary approach compared to other traditional concert halls. The objective of this paper is to examine forms and organic system of functions of this concert hall in order to re-evaluate it's historical meanings in our modern architecture history, The current study will also look into how the personal background of Hans Scharoun has influenced his design in various ways, especially the inside of lobby and auditorium of Berlin Philharmonic Concert Hall.

To improve the performance of blue fluorescent and green phosphorescent organic light-emitting diode devices, Merck developed novel green phosphorescent host and electron-transporting materials. The newly developed electron-transporting material improves the external quantum efficiency of blue fluorescent devices up to 8.7%, with an excellent lifetime. In combination with the newly developed host materials, the efficiency of green phosphorescent devices can be improved by a factor of 1.7, and the lifetime by a factor of 7.

Methyl glycidyl ether has been polymerized in a controlled fashion at low temperature in toluene using the combination of tetraoctyl ammonium bromide and triisobutyl aluminum. Poly(glycidyl methyl ether)s with molar masses ranging from 3 000 to about 90 000 g/mol and narrow polydispersities (<1.2) were prepared and the dependence of their solubility and LCST in water as a function on their molar masses investigated.
