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.

Tan, Yu,Luo, Shilong,Li, Dongmei,Zhang, Nan,Jia, Shiqi,Liu, Yidong,Qin, Wenling,Song, Choong Eui,Yan, Hailong American Chemical Society 2017 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.139 No.18

<P>Structural motifs containing contiguous halide bearing stereocenters are common in natural products as well as bioactive molecules. A few successful examples have been reported in the area of asymmetric vicinal dihalogenation of alkenes for accessing dihalogenated products; in this report, an alternative generation method of contiguous halide-bearing stereocenters alpha,beta,gamma,delta relative to carbonyl group in excellent enantioselectivity is proposed by utilizing a Song's oligoEG catalyst-catalyzed asymmetric beta-elimination. According to this methodology, a wide range of anti-syn-trihalides and anti-syn-anti-tetrahalides with high levels of enantioselectivity were synthesized. The synthetic utility of the contiguous halide-bearing stereocenters was demonstrated by several transformations. The results of high-resolution mass spectrometry indicated that the favorable interaction between catalyst and one of the enantiomers of racemic contiguously multihalogenated ketone contributed to the original enantioselectivity of dehydrohalogenation. A deuterium kinetic isotope effect experiment revealed that this beta-elimination reaction proceeds by the E2 mechanism. This strategy opens a new pathway for the asymmetric synthesis of contiguous halide bearing stereocenters of great complexity.</P>

Xinyan Xie,Fang Hou,Li Li,Yanlin Chen,Lingfei Liu,Xiu Luo1,Huaiting Gu,Xin Li,Jiajia Zhang,Jianhua Gong,Ranran Song 대한신경정신의학회 2019 PSYCHIATRY INVESTIGATION Vol.16 No.5

Objective: To evaluate the association of GRIK2 and NLGN1 with autism spectrum disorder in a Chinese population. Methods: We performed spatio-temporal expression analysis of GRIK2 and NLGN1 in the developing prefrontal cortex, and examined the expression of the genes in ASD cases and healthy controls using the GSE38322 data set. Following, we performed a case-control study in a Chinese population. Results: The analysis using the publicly available expression data showed that GRIK2 and NLGN1 may have a role in the development of human brain and contribute to the risk of ASD. Later genetic analysis in the Chinese population showed that the GRIK2 rs6922753 for the T allele, TC genotype and dominant model played a significant protective role in ASD susceptibility (respectively: OR=0.840, p=0.023; OR=0.802, p=0.038; OR=0.791, p=0.020). The NLGN1 rs9855544 for the G allele and GG genotype played a significant protective role in ASD susceptibility (respectively: OR=0.844, p=0.019; OR=0.717, p=0.022). After adjusting p values, the statistical significance was lost (p>0.05). Conclusion: Our results suggested that GRIK2 rs6922753 and NLGN1 rs9855544 might not confer susceptibility to ASD in the Chinese population.

Objective: To determine whether noncontrast computed tomography (NCCT) models based on multivariable, radiomics features, and machine learning (ML) algorithms could further improve the discrimination of early hematoma expansion (HE) in patients with spontaneous intracerebral hemorrhage (sICH). Materials and Methods: We retrospectively reviewed 261 patients with sICH who underwent initialNCCT within 6 hours of ictus and follow-up CT within 24 hours after initial NCCT, between April 2011 and March 2019. The clinical characteristics, imaging signs and radiomics features extracted from the initial NCCT images were used to construct models to discriminate early HE. A clinical-radiologic model was constructed using a multivariate logistic regression (LR) analysis. Radiomics models, a radiomics-radiologic model, and a combined model were constructed in the training cohort (n = 182) and independently verified in the validation cohort (n = 79). Receiver operating characteristic analysis and the area under the curve (AUC) were used to evaluate the discriminative power. Results: The AUC of the clinical-radiologic model for discriminating early HE was 0.766. The AUCs of the radiomics model for discriminating early HE built using the LR algorithm in the training and validation cohorts were 0.926 and 0.850, respectively. The AUCs of the radiomics-radiologic model in the training and validation cohorts were 0.946 and 0.867, respectively. The AUCs of the combined model in the training and validation cohorts were 0.960 and 0.867, respectively. Conclusion: NCCT models based on multivariable, radiomics features and ML algorithm could improve the discrimination of early HE. The combined model was the best recommended model to identify sICH patients at risk of early HE.

Luo Jie(Jie Luo),박세훈(Se-hun Park),송풍근(Pung-keun Song) 한국표면공학회 2009 한국표면공학회지 Vol.42 No.3

Ga/Al doped ZnO (GAZO) thin films were prepared on non-alkali glass substrate by co-sputtering system using two DC cathodes equipped with AZO (Al2O3:2.0 wt%) target and GZO (Ga₂O₃:6.65 wt%) target. This study examined the influence of Al/Ga concentration and substrate temperature on the electrical, structural and optical properties of GAZO films. The lowest resistivity 1.95×10<SUP>?3</SUP> Ω㎝ was obtained at room temperature. With increasing substrate temperature, resistivity of GAZO film decreased to a minimum value of 7.47×10<SUP>?4</SUP>Ω㎝ at below 300℃. Futhermore, when 0.05% H₂ gas was introduced, resistivity of GAZO film decreased to 6.69×10<SUP>?4</SUP>Ω㎝. All the films had a preferred orientation along the (002) direction, indicating that the deposited films have hexagonal wurtzite structure formed by the textured growth along the c-axis. The average transmittance of the films was more than 85% in the visible light range.

Zhi-Ming Luo,Gyu Moon Song,Tae Yoon Kim 한국통계학회 2011 Journal of the Korean Statistical Society Vol.40 No.4

In this paper, we derive the central limit theorem (CLT) for quadratic error where the Nadaraya-Watson regression estimator is employed under dependence. Our results may be applicable for various nonparametric regression models including nonlinear autoregressive model. In addition, we discuss the usefulness of our results for obtaining test statistics specifying a regression model under dependence. The proof uses CLT for variable degenerate U-statistics due to Kim and Luo (in press).
