Simplicity Characteristics Analysis of 20th Century Women’s Clothing using S-Polygon

Emotional simplicity is quite attractive in a modern life. Previous studies on clothing simplicity have described the visual simplicity of clothing with the characteristics of individual design elements such as lines, colors and textiles. However, the observer perceives the visual object from an integrated perspective not only from a detailed point of view. Therefore, a holistic approach to visual characteristics of clothing appearance is required. This study is a comprehensive a analysis of how the visual characteristics of 20th century western women’s clothing are expressed by the interaction of the simplicity factors that are components of S-Polygon. For this purpose, a total of 400 fashion images to represent each decade of 20th century was chosen from 11 published materials related to the history and culture of clothes as well as Internet sites that included samsungdesign.net, firstview.com, and redlist.com. Analyzing the visual characteristics of western women\u27s clothing in 20th century using the S-Polygon makes it possible to interpret changes in women\u27s clothing in terms of simplicity. And it is possible to understand the relationship between factors that constitute the visual simplicity of the clothing and to identify various characteristics of visual simplicity shown in clothing. A comparison and analysis between multiple designers in terms of simplicity, using the S-Polygon will make it possible to propose new ways to design

Study on National HR Competitiveness Assessment: Current Trends and Future Directions

2007This study attempts to develop a set of indicators to assess human resource competitiveness. To meet this purpose, the current status of the national competitiveness assessment model as well as its development process was reviewed. Also, by extracting indicators related to human resources from the national competitiveness assessment model, the strengths and weaknesses of the assessment method of national and HR competitiveness were analyzed. HR related theories were critically reviewed, and the implication of each theory was suggested. Based on these analyses, a HR competitiveness assessment model and indicators were developed.This work was financially supported by a grant (KRF-2005-005-J16701) from the Korea Research Foundation

Recovery of ammonia from wastewater by liquid-liquid membrane contactor: A review

Liquid-liquid membrane contactor (LLMC), a device that exchanges dissolved gas molecules between the two sides of a hydrophobic membrane through membrane pores, can be employed to extract ammoniacal nitrogen from a feed solution, which is transported across the membrane and accumulated in a stripping solution. This LLMC process offers the promise of improving the sustainability of the global nitrogen cycle by cost-effectively recovering ammonia from wastewater. Despite recent technological advances in LLMC processes, a comprehensive review of their feasibility for ammonia recovery is rarely found in the literature. Our paper aims to close this knowledge gap, and in addition to analyze the challenges and provide potential solutions for improvement. We begin with discussions on the operational principles of the LLMC process for ammonia recovery and membrane types and membrane configurations commonly used in the process. We then assess the performance of the process by reviewing publications that demonstrate its practical application. Challenges involved in the implementation of the LLMC process, such as membrane fouling, membrane wetting, and chemical requirements, are presented, along with discussions on potential strategies to address each. These strategies, including membrane modification, hybrid process design, and process optimization based on cost-benefit analysis, guide the reader to identify key areas of future research and development.N

Photoinduced self-assembly of TiO2 and SiO2 nanoparticles on sidewalls of single-walled carbon nanotubes

Highly selective self-assembly of TiO2 and SiO2 nanoparticles (NP) on the sidewalls carbon nanotubes (SWNT) by a simple UV irradiation in aqueous media without using organic molecules were reported. SWNT were grown on Si wafers from Fe ion coated TiO2 NP catalysts by using chemical vapor deposition (CVD) method. The results show that the surface of SWNT is positively charged due to the increased hole concentration in SWNTs, which are induced by negative charges built on the underneath p-tupe Si upon UV irradiation. The NPs are not found to posses a self-assembly when the sample is not irradiated and when pH of the reaction solution is kept at 1 to alter the surface charges of NPs. The results also show that the self-assembly of TiO 2 NOs are also achieved by using externally provided NPs.close242

Caspase-2 primes cancer cells for TRAIL-mediated apoptosis by processing procaspase-8

Although caspase-2 is believed to be involved in death receptor-mediated apoptosis, the exact function, mode of activation, and regulation of caspase-2 remain unknown. Here we show that protein kinase (PK) CK2 phosphorylates procaspase-2 directly at serine-157. When intracellular PKCK2 activity is low or downregulated by specific inhibitors, procaspase-2 is dephosphorylated, dimerized, and activated in a PIDDosome-independent manner. The activated caspase-2 then processes procaspase-8 monomers between the large and small subunits, thereby priming cancer cells for TNF-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis. The processed procaspase-8 that is recruited to death-inducing signaling complex by TRAIL engagement becomes fully activated, and cancer cells undergo apoptosis. PKCK2 activity is low in TRAIL-sensitive cancer cell lines but high in TRAIL-resistant cancer cell lines. Thus, downregulating PKCK2 activity is required for TRAIL-mediated apoptosis to occur in TRAIL-resistant cancer cells. Our data provide novel insights into the regulation, mode of activation, and function of caspase-2 in TRAIL-mediated apoptosis
