<P>We report a novel one-step bottom-up fabrication method for multiscale-structured black Si, which is characterized by randomly distributed microscale Si layers covered with sub-100 nm protrusions with submicron boundary grooves. The unique multiscale structure, suggested as a “nanocanyon,” effectively minimizes light reflection over a broad spectrum by diversifying the scattering routes from the nanotextured surface to the wide distributed boundary micronanoscale grooves. This structure was achieved by hydrophobic clustering and local aggregation of instantaneously melted Si nanocrystals on a glass substrate under laser irradiation. This method can replace the complicated conventional silicon processes, such as patterning for selective Si formation, texturing for improved absorption, and doping for modifying the electrical properties, because the proposed method obviates the need for photolithography, chemical etching, vacuum processes, and expensive wafers. Finally, black Si photosensor arrays were successfully demonstrated by a low-cost solution process and a laser growth sintering technique for microchannel fabrication. The results show the great potential of the proposed fabrication method for low-cost and sustainable production of highly sensitive optoelectronics and as an alternative to conventional wafer-based photosensor manufacturing techniques.</P> [FIG OMISSION]</BR>

<P>An effective mask-free method for fabricating high-aspect-ratio pillarlike nanostructures over a large area of a quartz surface via a simple O<SUB>2</SUB> and CF<SUB>4</SUB> two-step reactive ion etching (RIE) procedure is developed. The nanostructured quartz surfaces are successfully combined with the engineered viral particles derived from hepatitis B virus capsid, yielding a novel 3D assay system with attomolar sensitivity, which has great potential for use in sensitive and early detection of various disease markers.</P> <B>Graphic Abstract</B> <P>Nanostructured quartz surfaces are densely covered with probe antibodies in a controlled orientation via engineered viral nanoparticles, leading to the preparation of a 3D assay system. The successful application of this nanostructured quartz-based assay system to highly sensitive detection of disease markers is reported. <img src='wiley_img_2010/1616301X-2010-20-12-ADFM200902054-content.gif' alt='wiley_img_2010/1616301X-2010-20-12-ADFM200902054-content'> </P>

This study was aimed to investigate the undergraduates`` awareness of caregiving for the elderly. It has conducted preliminary study to verify validity of the measuring instrument survey to 30 students among undergraduates in Daegu Hanny University from 1 to 5 April 2008. Then,. it deleted, revised or corrected some items and it performed the field survey to 250 students from 15 April to 31 May 2008. The results were as follows. 1. By general characteristics, 250 subjects were classified into 99 men (39.6%) and 151 women (60.4%); 69 freshmen (27.6%), 82 sophomores (328%), 76 juniors (30.4%) and 23 seniors (9.2%).2. With regard to awareness of caregiving for the elderly, economic caregiving awareness was the strongest in this study(4.24), followed by service (4.04) and emotional (3.83).3. The economic caregiving awareness was highest in students aged between 22 and 24 (4.43) (p<O.05). The awareness was greatest in only child (4.54) (p<O.01). Regarding to health status of parents, it showed 4.36 of supporting awareness in the group answered ``my parents are healthy``. It meant that health status of parents affects the economic caregiving awareness (p<O.05).4. With regard to the emotional caregaiving awareness, it was highest in undergraduates aged between 22 and 24 (4.01) (p<O.05) and in the group with healthy parents (p<0.01).5. In the case of the service caregiving awareness, it was 3.92 in the group with somewhat unhealthy parents; 4.00 in students with somewhat healthy parents 4.14 in the group with healthy parents. There was a significant difference between the groups (p<O.01).6. In the correlation among those awareness, it showed a strong correlation between the emotional and service caregiving awareness (r=O. 730). 7. As the result of regression analysis, awareness for the aged was significantly affected by birth order (13=.148), religion (13=.127) and health status of parents (13=.168). In other words, the awareness was greater in the only child, in the student with religion or with healthy parents.

Subjects were separated by 3 groups, the first group Participated to exercise combined with diet limitation program (EDG, N=9), another group Participated to only exercise program (EG, N=10) and the other group participated to only diet limitation program (DG, N=8), respectively. Calories per day for subjects in EDG and DG limited to l,800㎉ and subjects of EDG and EG exercised 5 days/week for 4 weeks. Results are as followed: 1) Leptin levels were significantly reduced among all the groups, which three interventions used in all the groups had effects of enhancing appetite. Ghrelin showed significant interactions among 3 groups, which those of EDG and DG were significantly enhanced but that of EG decreased after 4 weeks. Thus, we might think that only exercise training used in EG had an effect of suppressing appetite. 2) TC was significantly reduced in EDG. TG was significantly decreased in EDG and DG. 3) Body weight, fat mass and percent fat were significantly decreased in EDG. Fat mass and %fat of EG were significantly decreased and muscle mass of EG was significantly increased after 4 weeks. PEl was significantly increased in EDG and EG. There were significant effects of interactions in strength (F=4.273, P<.05) and muscular endurance (F=9.506, P<.001) of EDG and EG, respectively. These findings suggest that the exercise combined diet limitation program for short duration enhanced appetite regulating hormones, decreased lipid profiles, and increased health-related fitness in young male adults.
