미국 아동복지 정책에 대한 무수한 연구에도 불구하고, 미국 내 정책 연구의 초점은 어머니의 아동양육 책임과 역할에만 맞추어져 왔다. 어머니만이 자녀 양육의 전적인 공헌자임을 입증하는 임상연구 결과의 부재 속에서도, 미국 아동관련 사회복지 정책은 아동양육의 전적인 책임이 어머니에게 있다는 사회적 통념을 반영하고 있는 것이다. 더 나아가, 현재의 미국 사회복지 정책은 아버지들이 가정 내에서 아동 양육에 참여할 기회를 제공하고 있지 않아, 아버지와 어머니 사이의 자녀 양육 역할 분담 불균형이 조장된다는 우려가...

The purpose of this study is to explore the relationship between leisure motivation and enduring involvement. Based on the literature suggesting that motivation and involvement are best conceptualized as multidimensional, we developed a model in which all dimensions of motivation positively influence three facets of enduring involvement. Furthermore, it was hypothesized that respondents’ gender moderates the motivation-involvement relation. Data were collected from 860 visitors to Cleveland...

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...

With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption...

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].

Fe3O4/GCE. The electrocatalytic ability of Fe3O4 was mainly attributed to the formation of Fe(VI) during the anodic scan, and its reduction to Fe(III) on the cathodic scan facilitated the sensing of CAP. The effects of pH and scan rate were measured to determine the optimum conditions at which the Fe3O4/GCE exhibited the highest sensitivity with a lower detection limit. The reduction current for CAP was proportional to its concentration under optimized conditions in a range of 0.09-47 μM with a...

Activated carbons (ACs) have been used as electrode materials of electric double-layer capacitors (EDLC) due to their high specific surface areas (SSA), stability, and ecological advantages. In order to make high-energy-density ACs for EDLC, petroleum pitch (PP) precarbonized at 500?1000°C in N2 gas for 1 h was used as the electrode material of the EDLC after KOH activation. As the pre-carbonization temperature increased, the SSA, pore volume and gravimetric capacitance tended to decrease, but...

Nitrogen-doped carbon nanosheets with a developed porous structure were prepared from polyurethane foams by hydrothermal carbonization following ZnCl2 chemical activation. Scanning electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, solid state 13C nuclear magnetic resonance (NMR) spectra and X-ray photoelectron spectroscopy were used to characterize the nitrogen-doped carbon nanosheet structure and composition. The removal of Cr(VI) by the N-doped carbon...
