Purpose: This study aimed to examine the relationships between the N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels with the sociodemographic and clinical factors, self-care behaviors, and the physical symptom experiences in patients with heart failure. Methods: This cross-sectional study utilized a convenience sample of adult outpatients and inpatients who attended a cardiology department in a tertiary hospital in Seoul, Korea. The data from 154 patients with heart failure were...

음악은 청취자에게 여러 가지 반응을 일으키게 할 수 있는 역동적인 경험(White, 2000)으로, 음악이 치료에 사용되는 기본원리 중 동질의 원리(iso-modic principle; same mode principle)는 대상자의 기분이나 템포와 동질의 음악을 들려주어 관심을 이끈 다음, 치료적으로 바람직한 기분의 방향으로 음악을 전환시켜 가는 기법이다(Aldridge, 1993). 이런 효과를 치유적 형태로 이용하는 것이 음악요법으로, 음악은 생리적으로 심박동수, 혈압, 호흡 및 면역기능과 스트레스 호르몬 등의 변화를 가져오고, 심리적으로는 상상력과 지능을...

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is...

Interconnected meso/microporous activated carbons were prepared from pumpkin seeds using a simple chemical activation method. The porous carbon materials were prepared at different temperatures (PS-600, PS-700, PS-800, and PS-900) and demonstrated huge surface areas (645?2029 m2 g?1) with excellent pore volumes (0.27?1.30 cm3 g?1). The wellcondensed graphitic structure of the prepared activated carbon materials was confirmed by Raman and X-ray diffraction analyses. The presence of heteroatoms (O...

nanofibers were activated with steam at various temperatures followed by subsequent carbonization to make carbon nanofibers with a highly conductive graphitic structure. Steam activation was effective in facilitating gas adsorption onto the carbon nanofibers due to the increased surface area. The carbon nanofibers activated at 800°C had a larger surface area and a lower micro pore fraction resulting in a higher variation in electrical resistance for improved CO gas sensing properties.

In gas adsorption processes, activated carbon fibers (ACFs) are used for the adsorption of the harmful gases that are generated by coal or oil combustion, and they have been widely studied [1,2]. ACFs have been used for harmful gas removal because of their specific surface area, micropores, reproducibility, safety, and processing ability, which are beneficial properties for a wide range of applications [3,4].

Carbon foams (CFms) are of crucial importance in electrical and mechanical devices due to their high thermal conductivity used for eliminating high heat flow and maintaining low temperatures [1]. The most common CFms are types of aluminum alloys, copper and diamond. However, the mechanical properties of metal-based heat sink materials are difficult to control at temperatures over 550°C [2,3]. Thus, CFms are actively investigated as heat sink materials because of their good properties, such as...
