  • 호주 연방산업과학연구회(CSIRO)는 1949년에 설립되어 호주 국내외에 56개의 연구소를 거느린 거대 연구 조직이다. 본고에서는 향후 CSIRO와 국내 소재연구 기관 간의 국제협력 관계 증진을 목표로 호주 연방산업과학연구회(CSIRO)의 인력, 예산, 조직 등 운영 현황과 전략 및 소재관련 연구분야를 소개하고자 한다. 전략적으로 CSIRO는 외부기관과의 협력 관계 증진, 과학기술 관련 지식의 유지 및 발전, 운영 절차의 간소화에 중점을 두고 이를 달성하는데 노력을 기울이고 있다. 또한 CSIRO의 소재관련 연구는 CSIRO 소재과학 및 공정(CSIRO Materials Science and Engineering)본부, CSIRO 공정과학 및 엔지니어링(CSIRO Proces Science and Engineering)본부, 경량소재 플래그십(Light Metals Flagship)에서 중점적으로 수행하고 있다.

  • A special group of polymers, those from renewable resources, has attracted an increasing amount of attention over the last two decades, due to two major reasons: environmental concerns and the limitations of our finite petroleum resources. Generally, polymers from renewable resources (PFRR) can be classified into three groups: (1) natural polymers, such as starch, protein and cellulose; (2) synthetic polymers from natural monomers, such as polylactic acid (PLA); and (3) polymers from microbial fermentation, such as polyhydroxybutyrate (PHB). Like many other petroleum based polymers, various properties of PFRR are also vastly improved through blending and composites formation.

  • GCM and scenario uncertainties are first investigated for 5 major watersheds (Han River, Paldang dam, Namhan River, Bukhan River and Imjin River watersheds). As a result of this study, it is found that CCSM3-based annual precipitation increases linearly with respect to the 10-year moving average values while CSIRO-based precipitation does not show much of trend. The results from annual DJF mean precipitation show a similar trend with respect to their 10-year moving average values. Both CCSM3- and CSIRO-based annual JJA mean precipitation do not show much of trend toward 21st century. In general, CCSM3-based precipitation values are slightly higher than CSIRO-based values with respect to their annual and annual JJA mean precipitation values, but CSIRO-based annual DJF mean precipitation values are slightly higher than CCSM3-based values. In case of mean air temperature between CCSM3 and CSIRO during 21st century, all of results show a clear trend in warming with the passage of time for 5 watersheds. However the upward trends from CCSM3-based values slow down toward end of 21stcentury while CSRIO-based values increases almost linearly.

  • The design and synthesis of novel biomolecular materials, based on mimicking the properties of molecules found in nature, is providing materials with unusual properties. Resilin serves as an energy storage material in insects and facilitates flight, jumping (in fleas, froghoppers etc) and sound production (cicadas, etc). Resilin is initially produced as a soluble protein and in its mature form is crosslinked through formation of dityrosine units into a very large insoluble polymer. In the present study, we have synthesized a recombinant form of resilin that can be photochemically cross-linked into a resilient, rubber-like biomaterial that may be suitable for spinal disc implants. This material is almost perfectly elastic and its fatigue lifetime in insects must be >500 million cycles.

  • 본 연구에서는 현재 및 미래기후에서의 가뭄심도-영향면적-지속기간 곡선의 비교를 통하여 극한 가뭄사상의 시공간적 거동에 대한 기후변화의 영향을 살펴보았다. 미래기후는 CGCM3.1-T63과 CSIRO-MK3.0으로부터 획득되었다. 분석 결과 CGCM3.1-T63의 경우에는 미래가뭄이 현재와 비슷할 것으로 예측되었으나, CSIRO-MK3.0의 경우에는 연강수량 총량의 변화가 거의 없음에도 불구하고 미래가뭄이 현재보다 더 극심해질 것으로 예측되었다. 이에 따라 현재의 수자원 공급 시스템에 대한 기후변화 취약성 평가가 시급함을 제시하고 있다.

  • The application of fertilizer P to Desmodium intortum at 40, 60 and 100 kg/ha resulted in the P content of the legume regrowth being 0.10, 0.13 and 0.16% on a dry matter basis. When the forages were fed alone to sheep in metabolism pens the corresponding voluntary intakes by sheep of the three forages were 27.3, 42.7 and $54.3g/W_{kg}{^{0.75}}$, respectively. Provision of additional P by rapid infusion into the rumen each morning before any fresh food was offered depressed the voluntary intake of all three feeds. It is suggested that the adverse effect of supplementary P was probably caused by an induced deficiency of either Ca or Mg and led to a reduction in microbial activity in the rumen.

  • Chemically pure, hydride/dehydride titanium powders were cold pre-compacted then extruded at $850^{\circ}C$ and $\sim450MPa$ under argon. The extrusions were 100% dense with a narrow band of surface porosity and equiaxed microstructure of similar magnitude to the starting material. The tensile properties of the bars were better than conventionally extruded CP titanium bar product. Outcomes from this study have assisted in the identification of a number of key characteristics important to the extrusion of titanium from pre-compacted CP titanium powders, allowing the elimination of canning and hot isostatic pressing (HIPping) of billets prior to extrusion as per conventional PM processes.
