<P>Anodic aluminum oxide (AAO) layers with nano-sized pores have been used as shadow masks for the fabrication of two-dimensional (2D) metal nanodot arrays (NDAs). However, the localized surface plasmon resonance (LSPR) of size-controlled NDAs fabricated using AAO masks has not been much studied. In this study, we report on the improved preparation method and utilization of an ultrathin AAO mask for the fabrication of 2D plasmonic metal NDAs. The greatest challenge in preparing an AAO mask is to control the pore diameter and to make it reproducible. AAO masks with size-controlled pores were reproducibly prepared using a two-step chemical wet etching method. Ag NDAs with different dot diameters (42, 60, and 80 nm) and Ag, Cu, and Au NDAs with dot a diameter of 80 ± 5 nm were fabricated on indium tin oxide glass substrates using AAO masks. The wavelengths corresponding to LSPR of 2D metal NDAs were investigated using ultraviolet-visible spectroscopy. Our results show that AAO masks with tunable pores can be used as shadow masks for the fabrication of 2D plasmonic NDAs.</P>

<P>A significant enhancement in the light output from nano-patterned InP substrate covered with a nanoporous alumina mask was observed. A uniform nanohole array on an InP semiconductor substrate was fabricated by inductively coupled plasma reactive ion etching (ICP-RIE), using the nanoporous alumina mask as a shadow mask. The light output property of the semiconductor substrate was investigated via photoluminescence (PL) intensity measurement. The InP substrate with a nanohole array showed a more enhanced PL intensity compared with the raw InP substrate without a nanohole structure. After ICP-RIE etching, the light output from the nanoporous InP substrate covered with a nanoporous alumina mask showed fourfold enhanced PL intensity compared with the raw InP substrate. These results can be used as a prospective method for increasing the light output efficiency of optoelectronic devices.</P>

<P>Two-dimensional gold (Au) nanodot arrays on a transparent substrate were fabricated for imaging of living cells. A nanoporous alumina mask with large-area coverage capability was prepared by a two-step chemical wet etching process after a second anodization. Highly ordered Au nanodot arrays were formed on indium–tin-oxide (ITO) glass using very thin nanoporous alumina of approximately 200 nm thickness as an evaporation mask. The large-area Au nanodot arrays on ITO glass were modified with RGD peptide (arginine; glycine; aspartic acid) containing a cysteine (Cys) residue and then used to immobilize human cancer HeLa cells, the morphology of which was observed by confocal microscopy. The confocal micrographs of living HeLa cells on Au nanodot arrays revealed enhanced contrast and resolution, which enabled discernment of cytoplasmic organelles more clearly. These results suggest that two-dimensional Au nanodot arrays modified with RGD peptide on ITO glass have potential as a biocompatible nanobioplatform for the label-free visualization and adhesion of living cells.</P>
A Study on the Site for the C&D Waste Treatment Complex in Urban Area

When environmental regulations were not strict, waste treatment facilities equipped with poor prevention of environmental pollution were often site in the outskirts of urban areas. However, due to concentration of population, industry, and culture, those facilities are surrounded by residential and commercial buildings, and have been emerging as a source of social conflict. There are such C&D facilities in Seoul which have been asked to move out by residents. To solve social conflicts caused by these facilities, constructing a C&D waste treatment complex and moving them into the complex was proposed as an option. This study shows the process and result of finding a site for the complex. The research started by housing demand survey, and then was followed by estimation of area, exploring candidate sites, optimal site selection, and discussion in order. There were 14 companies that wanted to move to the complex and land of 43,700m<sup>2</sup> was needed for their own. Adding extra area for roads, green space and supporting facilities to area of companies’ demand made the total area of 62,200m<sup>2</sup> on the minimum ground. Several indicators, such as present land use, access roads, obstacles, distance from waste source, utilities utilization, distance from residential area picked 8 candidate sites for the complex within urban area, 3 of which shown distinct advantages in terms of future expansion, accessibility, conflict with surrounding residents and local governments. 23 more elaborate indicators suggested optimal site, scoring 82 out of 100 and being a farmland close to an airport. In this study, it was not impossible to find out a little better site for the C&D waste treatment complex within urban area than existing site that scored 81. However, compared to the constructing the complex in a suburban area (scored 89), the construction of the complex at the optimal site located in urban area will require much more conflicts with residents or local governments, and economic burdens.

Aims: SBAR (Situation, Background, Assessment, and Recommendation) has been extensively used in clinical and educational settings. A structured communication program increases effective communication, education satisfaction, and positivity during interprofessional collaboration among students. This systematic review aims to identify and synthesize evidence on the effectiveness of SBAR-based simulation programs in nursing students. Methods: A research protocol was developed according to the PRISMA-P guidelines. The protocol of this study was registered on the PROSPERO (CRD42021234068). Eight bibliographical databases were searched for studies published between 2001 and 2021, using relevant search terms. Searches were conducted in PubMed, Embase, CINAHL, and Cochrane Library for literature in English, DBpia, KISS, RISS, and Kisti for literature in Korean. After screening titles, abstracts, and full-text papers, pertinent data were extracted and critical appraisal of the retrieved studies was undertaken. Data were analyzed using the framework approach and findings presented in a narrative summary. We used the Effective Public Health Practice Project (EPHPP) ‘Quality Assessment Tool for Quantitative Studies’ to assess the quality of included studies. Results: Twelve studies were included: 3 randomized controlled trials and 9 quasi-experimental studies. Two overarching themes were noted: communication clarity and critical thinking. The results of 6 out of 12 studies produced significant results in favor of SBAR-based simulation in terms of communication clarity. Divergent results were obtained with regard to communication ability, critical thinking, confidence, learning self-efficacy, and attitude on patient safety. The results of these studies highlighted the communication clarity ultimately leads to positive results in terms of patient safety of nursing students. Conclusion: This review provides a comprehensive update of the literature on the effectiveness of SBAR-based nursing simulation programs in nursing students. These programs were found to have positive learning outcomes as a result of clear, concise communication. Further studies on the effectiveness of various learning outcomes derived from the SBAR-based program are needed.
