골밀도 특성에 관한 연구는 문헌에 많이 발표 되어 있으며, 이러한 특성에 영향을 미치는 여러가지 다양한 요인들에 대한 내용도 다방면의 연구를 통해 알려졌다. 유전과 잘못된 식습관, 칼슘과 마그네슘의 보충상태, 천식치료를 위한 albuterol의 복용 등은 골밀도의 매개 변수에 많은 영향을 미친다. 또한 골의 크기는 무게에 대한 골의 저항이 골의 지름의 크기에 관련이 크기 때문에 골의 저항력에 매우 중요한 영향을 미친다. 특히, 폐경은 골밀도의 빠른 감소를 가져오는 결과가 되는 순환 에스트로겐의 수준이 낮아지는 원인이...

암은 한국인의 전체 사망원인의 27%로서 1위를 차지하고 있는 질병으로 심각 한 사회 문제로 대두되고 있다(통계청, 2009). 이중 유방암은 전체 암의 6.5%를 차지하며, 경계성장에 따른 물질적 풍요, 식생활의 서구화, 피임약의 사용, 출산 및 수유방법 등의 변화로 더욱 증가할 것으로 여겨진다(국립암센터, 2002). 이와 더불어 유방암은 다른 종류의 암과는 달리 여성에게서 많이 발생하며, 유방암 환자들은 유방암 수술로 인하여 통증과 같은 신체적 증상과 불안과 우울과 같은 정신적 약화가 나타나 일상생활이 제한되고 상당한...

Different phytochemicals obtained from various natural plant sources are used as reduction agents for preparing gold, copper, silver and platinum nanoparticles. In this work a green method of reducing graphene oxide (rGO) by an inexpensive, effective and scalable method using olive leaf aqueous extract as the reducing agent, was used to produce rGO. Both GO and rGO were prepared and investigated by ultraviolet and visible spectroscopy, Fourier-transform infrared, scanning electron microscopy,...

A significant body of previous research in physics, chemistry and biology has demonstrated that the properties of nano-composites are significantly different than those of the bulk materials [1]. Some unique phenomena, such as the quantum tunneling effect, and surface effects, have also been observed, and attributed to the large surface area and small size of the carbon nanomaterials. It has been reported that such nanomaterials exhibit high temperature sensitivity, high ductility, large surface...

of Type 3 through Type 5, in which the role of the EVA sheet is more prominent because it absorbs the impact energy rather than dispersing it, a clear form of puncture failure mode was observed. Based on the above results, it was found that all the observation values decreased as the EVA lamination increased compared with the CFRP lamination. The EVA lamination was thus found to have a very important role in reducing the impact. However, the strain and temperature were inversely propositional.

In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared...

By applying the size-strain plot method to the X-ray diffraction data, the crystallite size and the crystal strain was determined to be 42.46 nm and 0.000489897, respectively, which indicate a perfect crystallite structure. The field emission scanning electron microscopy image showed the presence of well-developed pores on the surface of the activated carbon. The presence of important functional groups was shown by the Fourier transform infrared spectroscopy spectrum. The adsorption of methyl...

sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity, which might be suitable for the adsorption of gasses. Moreover, carbon nanoparticles (CNPs) of this fly ash were produced in parallel using the ball milling technique, and were evaluated as reinforcements for epoxy based...

electron microscopy and transmission electron microscopy observations of the composite HAP/Gr powder indicated that nanosized hydroxyapatite particles were uniformly placed in the graphene overlay. Raman spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction confirmed graphene incorporation in the HAP/Gr powder. The electrochemically prepared HAP/Gr composite powder exhibited slight antibacterial effect against the growth of the bacterial strain Staphylococcus aureus.
