Function and diversity Collagen, which is present in all multicellular organisms, is not one protein but a family of structurally related proteins. It is the most abundant protein in mammals and is present in most organs of the body, where it serves to hold cells together in discrete units. It is also the major fibrou…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.

Principal realizations and applications of nanophotonic devices based on localized plasmons are considered
Carbon nanotubes with different morphology of the agglomerates have been obtained by CVD method, conditions for obtaining the CNT in bundles have been found. The methods of formation uniform layer of polyaniline on the surface of CNTs are developed. It is shown that the mass and structure of polyaniline deposited depe…

Abstract Review: 113 refs.
Complexity in understanding of the processes spotting the electrical properties of structured materials is considered from the side of the quantum representation of aperiodic structure. Determination of each of the view disordered aperiodic matrixes by means of statistical and energy parameters have allowed to describ…
Influence of structural state on mechanical properties of pure titanium and magnesium alloy WE43 as candidates for use as nondegradable (titanium) and degradable (WE43) medical implants was studied. By the methods of severe plastic deformation in combination with programmed heat treatment the nanostructured pure titan…
The non-traditional method of obtainingclusters of heterogenous and homogenous nanooxides, nitrides of aluminum by substitution ofoxygen atoms with low-energy nitrogen ions inthe solid phase inside the nanopores of aluminum oxide Al2O3 (nanosapfire) is proposed and implemented. The AlN, AlNxO1-x, Al2O3 nanolayers was…
고체분산체는 난용성약물의 용해도를 향상시키는 기술로 용출특성은 고분자의 성질, 고분자의 함량 및 물리화학적 성질에 의하여 변화한다. 본 연구에서는 이부프로펜과 셀룰로오스 아세테이트를 사용하여 분무건조와 로터리 증발법을 사용하여 고체분산체를 제조하였다. 제조한 고체분산체의 표면성질을 주사전자현미경(SEM)을 사용하여 분석하였으며, X선 회절기(X-RD)와 시차주사열량계(DSC)를 사용하여 결정성 변화를 관찰하였다. 고체분산체의 화학적 변화를 관찰하기 위하여 적외선 분광기(FTIR) 분석을 하였으며, 수분 친화도를 측정하기 위하여 수분접촉각 측정을 하였다. 용출 특성은…
Today, microsystem technology for biomedical applications spans a wide range of biosensors, implantable microdevices, and lab-on-a-chip systems. By reducing reagent volumes and costs, decreasing analysis times, and increasing throughput, micro total analysis systems (microTAS) promise to have large impact on healthcar…
Factors such as need for long-term treatment, narrow therapeutic window, complex dosing schedule, combination therapy, individualized or emergency dosing regimen, and labile active agents are presently outside of the capabilities of conventional drug administration.1 Drug delivery systems such as tablets or injections…
The performance of a material intended for biomedical applications depends on its interfacial properties and reactions that occur when come in contact with biological fluids. Non-specific protein adsorption at the biomaterial interface is the first and critical event that initializes a cascade of host responses, includin…
이 연구는 트위터의 해시태그 운동 사례로 팬덤의 활동을 다룬다. #팬덤 내 사이버 불링 아웃 해시태그 운동을 분석 사례로 삼았다. 이 연구는 해당 사례를 통해, 페미니즘과 팬덤의 문제를 논의하고, 공론화라는 문제 설정이 트위터라는 플랫폼의 문제와 온라인 토론의 가능성에 어떻게 연결되는지에 대해서 탐구하고자 한다. 특히, 페미니즘이 논쟁 과정에서 어떻게 의미화 되는지를 드러내고 이러한 의미 구성이 갖는 한계점에 대해서 논의하고자 한다. 연구 결과 한국 아이돌 팬덤 중 트위터 이용자들은 해시태그 운동을 페미니즘 문제제기는 물론 이 문제제기를 공론장에서 제거하기 위해서도…
