He, Qingqing,Luo, Quanming,Huang, Jian,Cao, Chi,Sun, Pengju,Du, Xiong The Korean Institute of Power Electronics 2020 JOURNAL OF POWER ELECTRONICS Vol.20 No.6

Multiple output LED drivers are necessary to achieve better performance and higher reliability in street lighting, tunnel lighting and LCD background lighting applications. Based on LCL-T constant-current characteristics, a modular multiple output LED driver is proposed in this paper. The LCL-T rectifiers are connected to the same voltage bus and work like current sources. However, since there are much higher voltage harmonics in the AC square bus voltage, it is very important to quantitatively analyze how these harmonics influence the precision of the output currents. In addition, all of the switches can achieve Zero Voltage Switching (ZVS) by proper design of the LCL-T network. Finally, a 200-W prototype with five channels is established with an efficiency of 92.25%.

Background/AimsAbdominal pain can be evoked or exacerbated after gastrointestinal cold stimulation in some patients with diarrhea-predominantirritable bowel syndrome (IBS-D), indicating a low temperature-induced sensitization of visceral perception. We investigated the roleof vagal transient receptor potential ankyrin 1 (TRPA1, a cold-sensing ion channel) in cold-aggravated visceral mechanonociception ina stress-induced IBS animal model. MethodsTRPA1 expression was examined in antral biopsies of healthy controls and IBS-D patients. Abdominal symptoms were assessed beforeand after warm or cold water intake. The visceromotor response (VMR) to colorectal distention (CRD) following intra-antral infusionof cold saline was measured in animals undergoing sham or chronic water avoidance stress. TRPA1 expression, extracellular signalregulatedprotein kinase 1/2 (ERK1/2) phosphorylation, and neuronal calcium influx in vagal afferents were assessed. ResultsCompared to healthy controls, IBS-D patients displayed elevated antral TRPA1 expression, which was associated with symptom scoresafter cold (4°C) water intake. Intra-antral infusion of cold saline increased VMR to CRD in naive rats, an effect dependent on vagalafferents. In stressed rats, this effect was greatly enhanced. Functional blockade and gene deletion of TRPA1 abolished the cold effecton visceral nociception. TRPA1 expression in vagal (but not spinal) afferents increased after stress. Moreover, the cold-induced, TRPA1-dependent ERK1/2 activation and calcium influx in nodose neurons were more robust in stressed rats. ConclusionsStress-exaggerated visceral mechanonociception after antral cold exposure may involve up-regulation of TRPA1 expression andfunction on vagal afferents. Our findings reveal a novel mechanism for abnormal gastrointestinal cold sensing in IBS.

Mi Suk Lee,Kyung Hee Chung,Song Mi Lim,Qingqing Luo 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

Fresh attention is being paid to lifestyle brands offering differentiated contents and value such that the 21st century is now being called the age of global lifestyle. Recently national income has been increasing and a broad lifestyle culture has been established. Thus, brands with Scandinavian (Sweden, Denmark, or Norway), culture sensitivity, and design have deeply permeated the domestic market which has led to a domestic consumers' lifestyle trend (Chung& Park, 2004; Kwon, 2013; Magnus & Chrystin, 2003). In particular, such global lifestyle brands as Marimekko (Finland), CathKidston (UK), and Muji (Japan) have secured competitiveness in the global market as textile products which reflect its country's cultural identity (Lee& Park, 2014). Meanwhile, a new word, Hanban (韓版)which refers to Korean brands or products that were created from the Korean wave (韓流), which refers to Korean dramas or songs. Korean culture has been commercialized and grafted into various industries. In particular, a strong wind of Hanban in fashion cultural products not only has spread the Korean lifestyle to the world, but has enhanced its influence on related industries as well as fashion. Although certain major Korean companies launched lifestyle brands such as Jaju, Modern House, Butter, and Pum to help realize a Korean lifestyle brand business, most products sold in Korean lifestyle brands focus on overseas imported goods,so it is difficult to find Korean images on these products(Bang, 2004; Lee & Chung, 2013). The size of the lifestyle market is growing as a high value-added industry that can lead consumers' lifestyle trends, and there is a growing interest for Korean fashion cultural products. Therefore, the purpose of this study is to attempt to develop textile designs for Korean-made high value-added products with the improvement of Korean brand values. For study methodology, the status of lifestyle brands at home and abroad was examined and textile designs were developed for lifestyle brand B. For the development of the textile designs, demand required by brand B was researched and a textile design concept was established based on fashion and interior decoration trends. Then, a textile was designed using a motive that can effectively represent the identity of brand B and the Korean image. Adobe Photoshop 6.0 and Adobe Illustrator CC programs were used for the standardized textile design motif, pattern development, and colorway. The results were as follows. First, global lifestyle brands such as Marimekko, CathKidston, and Muji sell differentiated lifestyle products from other brands by applying motifs and colors which symbolize their country's and city's cultural image on textile products and displaying their own identity and peculiarity. On the other hand, Korean lifestyle brands such as Casamia, Hanssem, Kosney, and Art Box do not plan or produce their own design, but will import and sell foreign textile fabric or textile products with high recognition, or copy imported fabric. Thus, their textile design is unsatisfactory to express their own identity and satisfy consumers' needs. Second, as to the development direction required by brand B, a Korean lifestyle brand, the focus was to first, 'design American and European products using colors and techniques which reflect Korean image trends', Second, to create a 'design with Scandinavia's peculiar simplified line and sensitive color', and finally, to make a 'flower pattern design with good sustainable market feasibility'. Based on the direction and 2015 S/S color and textile trends, three concepts were established: Global Tribe, Bunny in the Wonderland, and Beyond Nature. Global Tribe is a folk paintin g(Minhwa) representing the Korean image well, and was reinterpreted in a modern sense. Bunny in the Wonderland is a modern Scandinavian style design using a rabbit, a symbol of brand B, as the main motif. Beyond Nature used a flower motif in various expression techniques and images. A textile design was developed by extracting from a folk painting, a rabbit, and a flower motif and standardizing a motif in watercolor, pen, and graphic techniques. It was digitalized by a scanner and a pattern was made via the steps of color adjustment and repetition. Three kinds of textile designs were developed according to three concepts and four kinds of colorways were made for each design. This study attempted to develop a textile design as Korean-made high value-added textile products. It is meaningful to suggest textile design with Korean cultural images and brand identity. Further study will focus on the development of fashion cultural products and DIY products to commercialize developed textile design.

<P>Although genetic diversity has a cardinal role in domestication, abundant natural allelic variations across the rice genome that cause agronomically important differences between diverse varieties have not been fully explored. Here we implement an approach integrating genome-wide association testing with functional analysis on grain size in a diverse rice population. We report that a major quantitative trait locus, GLW7, encoding the plant-specific transcription factor OsSPL13, positively regulates cell size in the grain hull, resulting in enhanced rice grain length and yield. We determine that a tandem-repeat sequence in the 5'UTR of OsSPL13 alters its expression by affecting transcription and translation and that high expression of OsSPL13 is associated with large grains in tropical japonica rice. Further analysis indicates that the large-grain allele of GLW7 in tropical japonica rice was introgressed from indica varieties under artificial selection. Our study demonstrates that new genes can be effectively identified on the basis of genome-wide association data.</P>
