Kim, Jimin,Kim, Jong Cheol,Kim, Young-Gyun,Son, Hyun-Hee,Hyeon, Chang Ju,Kim, Ho Min,Lee, Haigun Institute of Electrical and Electronics Engineers 2018 IEEE transactions on applied superconductivity Vol.28 No.3

<P>This paper reports the effectiveness of metal-cladding (MC) winding technique employing a GdBCO tape with a micrometer-thick stainless-steel clad as experimentally compared with that of the partial insulation (PI) winding technique. The investigation included charge–discharge, sudden-discharge, and overcurrent tests. The charge–discharge and sudden-discharge tests showed that the charge/discharge process of the coil using the metal-clad GdBCO tape was considerably shorter than those of the PI coils, because the effective resistance of the MC coil was higher than those of the PI coils. Although the MC coil exhibited lower electrical stability than the PI coils did (when the current is high enough), the MC coil was virtually more stable than any fully insulated coil. This study confirms that the MC winding technique is promising for the development of electrically stable high-field magnets allowing relatively high rates of ramping up and down.</P>

Kim, Gook Hee,Woo, Sang Hun,Kim, Sang Done,Kim, Jimin,Kim, Suk Joon,Park, Deuk Soo The Society of Chemical Engineers, Japan 2010 Journal of chemical engineering of Japan Vol.43 No.3

<P>The effect of static mixer internals on the hydrodynamic properties and the axial gas mixing characteristics has been determined in a circulating fluidized bed riser of FCC catalysts. Two types of static mixer are used with the variation of superficial gas velocity and solid circulation rate. With the static mixer in the riser, the axial solid holdup is much higher than that without the static mixer and the bottom acceleration length is shortened. The axial gas dispersion coefficients in the riser decrease with increasing solid circulation rate with the R–R configuration static mixer.</P>

Jimin Kim,Eung Tae Kim,Ha Kyung Lee,Eunsoo Baek,Ho Jung Choo 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

Backed by the rapidly-growing economy, China sends the most tourists to Korea. Accordingly, growing consumption of Chinese tourists is strongly drawing attention of the Korean retail industry. Academia has conducted more relevant researches, such as effective branding of Korean Wave, and services to attract tourists. Despite a series of efforts, including specialized tour products and language services, there have been an increasing number of Chinese visitors complaining about their experience in Korea and Chinese tourists are urgently demanding improvements. Hence, comprehending sophisticated consumption behavior of Chinese tourists is becoming more important than ever before. Also, it needs to explore how shopping experiential value that they experience while purchasing fashion goods in Korea affects their satisfaction of the store and product. Previous literature has shown that perceived shopping value has a positive effect on customer satisfaction and behavioral intention (Mathwick et al., 2001). Previous domestic studies that targeted Chinese tourists have focused on investigating the shopping motivation and satisfaction (Ko, 2011) and market segmentation of Chinese tourist shoppers (Oh, 2014). Previous studies have approached this problem mainly from its cognitive aspect and few studies have focused on the emotional aspect during shopping. This study suggests that emotional behavior mediates the relationship between shopping experiential value and consumer attitude toward products and stores. According to the Korea Tourism Organization, the ratio of male to female Chinese tourists visiting Korea changed from 69:31 in 1995 to 59:41 in 2005. In 2013, female Chinese tourists outnumbered males at a ratio of 41:59. The number of Chinese female tourists continues to increase. Females are known to be more involved in fashion consumption. Hence, this study is conducted on 550 Chinese female tourists who have shopping experiences during their visit to Korea. The ages of the respondents range from 20 to over 50 years old, with a mean age of 33.5 years. Their shopping experiential value is measured by visual appeal, crowding, economic benefits, and service excellence, and is expected to trigger emotions of entertainment and escapism. Variables including entertainment and escapism are measured using the Experiential Value Scale developed by Mathwick et al. (2001). This study finds that three experiential values (visual appeal, crowding, and service excellence) have positive influences on entertainment. For example, customers feel greater entertainment when visual appeal, service excellence and/or the number of customers in the store is greater. The emotion of entertainment turns out to have positive impacts on both store satisfaction and product satisfaction. According to the examination of how shopping experiential values affect escapism, crowding and economic benefits have a positive impact, whereas visual appeal and service excellence have a negative impact on escapism. Previous studies define escapism as an emotion of which customers are absorbed by entertaining activities and satisfied with shopping. This study assumes that all the shopping experiential values may have a positive impact on escapism. Escapism is a status where customers are deeply occupied with shopping without thinking of anything as if they were in another world, and a much stronger emotion of entertainment than usual pleasure from shopping. This study finds that the higher visual appeal and service excellence tends to generate the lower the escapism. This may be attributable to the fact that the survey was examined only on Chinese tourists. The respondents were asked to recall the most memorable item among the fashion products that they purchased during their visit to Korea. Their shopping experiences varied widely from well-organized malls, like department stores and duty free shops, to crowded environments, like Dongdaemun, traditional markets and subway stores. As a result, different experiential values have different impacts on escapism. Economic benefits and crowding which are experienced during shopping help to absorb in shopping, and these are likely to have positive impacts on escapism. On the other hand, visual appeal and service excellence may have different influences on escapism according to the shopping environment that Chinese consumers experienced. For example, Dongdaemun or subway stores are less visually appealing than department stores or duty free shops, but trigger stronger sense of escapism. Because survey questions to measure service excellence include Chinese (language) proficiency of sales staff, it is expected that higher language proficiency level of sales staff tends to generate lower degree of escapism, the sense of feeling that one is indeed in foreign country like Korea, for customers. Escapism has negative impacts on both product and store attitudes. Escapism is a status of absorption in which customers are emotionally occupied with pleasant feelings, and purchases along with a high escapism are likely to be less rational and more impulsive. In particular, this study examines tourist shoppers, and the respondents evaluate products they purchased in another country after they return home, and this may have caused the negative attitude toward products and shops. In fact, some previous studies found that overly positive emotions have negative impacts on purchase behavior (Liljander &Standvik, 1997; Andrade, 2005). This study confirms that the shopping experiential values perceived by Chinese tourists affect their product and store attitudes through the emotions of entertainment and escapism. It is particularly notable that this study verifies diverse roles of different emotions such as entertainment and escapism in the context of tourist shopping. This study employs empirical analysis on tourists, and provides practical implications including the importance of shopping experiential values for developing retail strategies.

<P><B>Abstract</B></P> <P>All-solid-state lithium-ion batteries (ASLBs) are receiving considerable attention due to their safety superiority and high energy density (achieved by bipolar configuration). Inorganic solid electrolytes are explored as a key-enabling material of the ASLBs. However, their critical challenges, including grain boundary resistance, interfacial instability with electrode materials and complicated processability, remain yet unresolved. Here, we demonstrate a new class of gel electrolyte with reversible thixotropic transformation and abuse tolerance as an effective and scalable approach to address the aforementioned longstanding issues. The gel electrolyte consists of (fluoropolymer/cellulose derivative) matrix and liquid electrolyte. The reversible thixotropic transformation is realized via sol-gel transition based on Coulombic interaction of the polymer matrix with liquid electrolyte. This unusual rheological feature allows the gel electrolyte to be printed in various forms. In addition, the gel electrolyte shows low crystallinity, thus playing a viable role in delivering high ionic conductivity. Based on understanding of rheological/electrochemical characteristics of the gel electrolyte, we fabricate a form factor-free pouch-type cell assembled with the gel electrolyte using sequential screen-printing process. The resultant cell shows exceptional safety upon exposure to various harsh abuse conditions, along with decent electrochemical performance.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A new class of gel electrolyte with reversible thixotropic property is demonstrated. </LI> <LI> The gel electrolyte consists of (fluoropolymer/cellulose derivatives) and liquid electrolyte. </LI> <LI> A form factor-free pouch-type cell can also be assembled with the gel electrolyte. </LI> </UL> </P>

We report the realization of a widely tunable band gap in few-layer black phosphorus doped with potassium using an in situ surface doping technique. Through band structure measurements and calculations, we demonstrate that a vertical electric field from dopants modulates the band gap, owing to the giant Stark effect, and tunes the material from a moderate-gap semiconductor to a band-inverted semimetal. At the critical field of this band inversion, the material becomes a Dirac semimetal with anisotropic dispersion, linear in armchair and quadratic in zigzag directions. The tunable band structure of black phosphorus may allow great flexibility in design and optimization of electronic and optoelectronic devices.</P>

Park, Jimin,Kim, Hyun Soo,Lee, Seung Min,Yoon, Kanghyun,Kim, Woo-shik,Woo, Jong Shin,Lee, Sanghoon,Kim, Jin-Bae,Kim, Weon Hindawi Publishing Corporation 2015 Evidence-based Complementary and Alternative Medic Vol.2015 No.-

<P><I>Background.</I> Atrial fibrillation (AF) is the most common form of arrhythmia. Several trials have suggested that acupuncture may prevent AF. However, the efficacy of acupuncture for AF prevention has not been well investigated. Therefore, we designed a prospective, two-parallel-armed, participant and assessor blinded, randomized, sham-controlled clinical trial to investigate acupuncture in persistent AF (ACU-AF). <I>Methods.</I> A total of 80 participants will be randomly assigned to active acupuncture or sham acupuncture groups in a 1 : 1 ratio. Both groups will take the same antiarrhythmic medication during the study period. Patients will receive 10 sessions of acupuncture treatment once a week for 10 weeks. The primary endpoint is AF recurrence rate. Secondary endpoints are left atrium (LA) and left atrial appendage (LAA) changes in function and volume, and inflammatory biomarker changes. <I>Ethics.</I> This study protocol was approved by the institutional review boards (IRBs) of Kyung Hee University Hospital (number 1335-04). This trial is registered with clinicaltrials.gov NCT02110537.</P>
