사용후핵연료 금속전환체의 저장 안정성을 높이기 위해 금속전환체의 주성분인 금속우라늄과 산화 안정화물질로 알려져 있는 Nb을 첨가하여 모의 금속전환체 합금을 제작하였다. 모의 금속전환체 합금을 온도구간에서 순수 산소분위기로 산화시험을 수행하고 무게증가를 열중량 분석기(TGA)로 측정하였다. 산화 실험결과 U-Nb 모의 금속전환체는 순수 금속우라늄에 비하여 상당한 산화 저항성을 가졌다. U-Nb 합금의 경우 Nb의 함량 에 따라 각각 온도가 일 경우에는 1.61, 7.78, 11.76, 20.14배 , 에서 1.45, 5.98, 10.08, 11.15배, 에서 1.33, 4.82, 8.87, 6.84배 순수 금속우라늄에 비해 산화저항성이 향상되는 것으로 나타났다. 또한 Nb 합금에 대한 활성화에너지는 kcal/mol 로 나타났다. In order to enhance an oxidation resistance of the pure uranium metal under air condition, a small quantity of niobium(Nb) which is known to mitigate metal oxidation is added into uranium metal as an alloying element. A simulated metallic uranium alloy, U-Nb has been fabricated and then oxidized in the range of 200 to under the environment of the pure oxygen gas. The oxidized quantity in terms of the weight gain has been measured with the help of a thermogravimetric analyzer. The results show that the oxidation resistance of the U-Nb alloy is considerably enhanced in comparison with that of the pure uranium metal. It is revealed that the oxidation resistance of the former with the niobium content of 1, 2, 3, and 4 is : 1) 1.61, 7.78, 11.76 and 20.14 times at the temperature of\;1.45, 5.98, 10.08 and 11.15 times at \;1.33, 4.82, 8.87 and 6.84 times at \; higher than that of the latter, respectively. Besides, it is shown that the activation energy attributable to the oxidation is 17.1321.92 kcal/mol/

촉진수송은 기존의 고분자 막에서는 힘든, 투과도와 선택도를 동시에 향상시킬 수 있는 기술 중 한 가지이다. 촉진 수송 분리막을 이용한 올레핀/파라핀 분리는 기존의 증류공정을 대체할 수 있는 기술로써 많은 관심을 받아왔다. 본 연구에서 는 테트라플루오로붕산은/질산알루미늄의 혼합염이 포함된 고분자 블렌드 기반의 촉진수송 올레핀 분리막을 제조하였다. 자유 라디칼중합법을 이용하여 폴리다이메틸실록세인-g-폴리옥시에틸렌 메타크릴레이트 가지형 공중합체를 합성하였다. 또한, 폴리 다이메틸실록세인-g-폴리옥시에틸렌 메타크릴레이트 매질에 폴리에틸렌옥사이드를 다양한 비율로 혼합하였다. 폴리에틸렌옥사 이드를 폴리다이메틸실록세인-g-폴리옥시에틸렌 메타크릴레이트 가지형 공중합체 질량 대비 70%를 혼합하였을 때, 혼합기체 선택도 및 투과도는 5.6 및 10.05 GPU에 도달하였다. 이와 같은 복합막의 올레핀 분리 성능이 향상된 이유는, 분리막에 첨가 된 은이온이 올레핀 기체분자의 선택적인 촉진 수송을 하였고, 또한 고투과성의 고분자 블렌드가 사용되었기 때문이다. 또한 은이온의 은나노입자로의 환원을 억제시키는 질산알루미늄의 첨가로 인해 복합막의 장시간 안정도를 향상시킬 수 있었다. Facilitated transport is one of the possible solutions to simultaneously improve permeability and selectivity, which is challenging in conventional polymer-based membranes. Olefin/paraffin separation using facilitated transport membrane has received much attention as an alternative solution to the conventional distillation process. Herein, we report olefin separation composite membranes based on the polymer blends containing AgBF4/Al(NO3)3 mixed salts. Free radical polymerization process was used to synthesize an amphiphilic graft copolymer of poly(dimethyl siloxane)-graft- poly(ethylene glycol) methyl ether methacrylate (PDMS-g-POEM). In addition, poly(ethylene oxide) (PEO) was introduced to the PDMS-g-POEM graft copolymer to form polymer blends with various ratios. The propylene/propane mixed-gas selectivity and permeance reached up to 5.6 and 10.05 GPU, respectively, when the PEO loading was 70 wt% in polymer blend. The improvement of olefin separation performance was attributed to the olefin facilitating silver ions as well as the highly permeable blend matrix. The stabilization of silver ions in the composite membrane was achieved through the introduction of Al(NO3)3 which suppressed the reduction of silver ions to silver particles.

This study investigated possible involvement of photoperiodic regulation in reproductive endocrine system of female olive flounder. To investigate the influence on brain-pituitary axis in endocrine system by regulating photoperiod, compared expression level of Kisspeptin and sbGnRH mRNA in brain and FSH-β, LH-β and GH mRNA in pituitary before and after spawning. Photoperiod was treated natural photoperiod and long photoperiod (15L:9D) conditions from Aug. 2013 to Jun. 2014. Continuous long photoperiod treatment from Aug. (post-spawning phase) was inhibited gonadal development of female olive flounder. In natural photoperiod group, the Kiss2 expression level a significant declined in Mar. (spawning period). And also, FSH-β, LH-β and GH mRNA expression levels were increasing at this period. However, in long photoperiod group, hypothalamic Kiss2, FSH-β, LH-β and GH mRNA expression levels did not show any significant fluctuation. These results suggest that expression of hypothalamic Kiss2, GtH and GH in the pituitary would change in response to photoperiod and their possible involvement of photoperiodic regulation in reproductive endocrine system of the BPG axis.

달리기 시 일정한 속도에서 보폭 차이가 하지 관절의 3 차원 모멘트에 미치는 영향

류지선 한국운동역학회 2002 한국운동역학회지 Vol.12 No.1

The purpose of this study was to determined the force and moment of the ankle and the knee joint at different step length relative to the length of the lower extremity during a steady running. Six digital cameras(Qualisis) and a forceplatform(A.M.T.I) were used to obtain the kinematic data of the segments and kinetic data on the running at speed of 5.18m/s. The force and moment measured from six subjects participated in this study were limited to the support phase and their values were averaged at the moment of heel strike, mid stance, and toe off of a running for making a comparison between the condition 1(relative step length 1.1) and the condition 2(relative step length 1.4). It was concluded that internal forces except mediolateral force of the condition 2 were greater in the ankle and the knee joint than those of the condition 1, but all moments of condition 2 were greater from the descriptive statistic point of view. For the future study, it was needed to consider a number of subjects, a various running speed, and a individual step preference for applying generally results to the running strategy.
