Purpose: Recently, Korean cosmetics distribution market has been reorganized with the H&B store. In the domestic cosmetics distribution market, existing brand road shops are decreasing, and multi-shops are leading the H & B stores, which have greatly improved their experience and content. In these environmental changes, the offline distribution channels are turning into the multi-editing shops that have introduced products of various brands and greatly enhanced experiences and contents. Nevertheless, most studies of factors and measurement items for measuring customer experience in the H&B store use Schmitt (1999)'s Strategic Experience Modules (SEMs). Therefore, the purpose of this study is to propose a measure that is practicable through consideration of the in-store customer experience components of the H&B store. Research design, data and methodology: Based on Schmitt's Strategic Experience Modules (SEMs), which are widely used in customer experience marketing, the metric pool was constructed through customer and literature research on H & B store managers. Since then, 101 preliminary surveys and 211 main surveys have been conducted in order to propose a dimension of customer experience and refine the metrics. Results: As a result of the research, H&B store's customer experience was derived from a measurement model consisting of 19 measurement items in total of five dimensions: environmental experience, intellectual experience, behavioral experience, tech experience, and relationship experience. This study analyzed that compared to the existing Schmitt's Strategic Experience Modules (SEMs), (1) emotional experience expanded to environmental experience, (2) Cognitive and relationship experiences are maintained (3) behavioral experience was subdivided into physical and technical experiences. In particular, the environmental experience has been proposed as a major component is an important point because the H&B store recently opened a large flagship store and is competitive in constructing a differentiated space. Conclusions: Related experience was seen as an important component of customer experience in the offline store, but in the process of refining the scale, interaction items with employees of the H&B store were removed, and rather, participation in the APP or SNS channel of the company, event Participation, interaction with other customers, etc. appear to be important, while suggesting the practical implications.

Purpose: This study was conducted with the goal of increasing research interest in H&B stores as a new distribution channel to identify factors influencing the revitalization of the H&B stores in Korea in distribution channels, in detail, the relationships among perceived values, satisfaction, trust, and loyalty. Research design, data and methodology: With 499 respondents, this study used exploratory factor analysis and reliability analysis to verify the reliability and validity of measured variables. Multiple regression was employed as a statistical method for the hypotheses of the study. Results: According to the results of the analysis, H&B stores are targeted by female customers in their 20s and 30s. The findings showed that four perceived values affect store satisfaction and trust. Store satisfaction and trust have positive effects on loyalty. Comparing the two variables, store satisfaction had a slightly stronger effect on loyalty than on trust. Conclusions: This study identified the store’s diverse values for the revitalization of the H&B stores need to provide to customers. The stores need to form facilities that can enhance the value of shops perceived by customers, and to establish distribution strategies that can further increase store satisfaction, trust, and loyalty to expand trading areas as multi-brand shops.

In a rapidly changing market, the companies are applying a variety of elements for promoting sales for the inflow of consumers. For the elements of sales promotion, the tendency to apply the experiential marketing that provides a positive recognition centering on the customers, and in such tendency, the consumers places the values on the experience obtained from the spatial elements of sales promotion provided by the companies. As it is reflected on the life style of consumers, the drugstores applied with the experiential marketing as a mean of sales promotion is rapidly growing in the distribution market. In this study, the elements of sales promotion was picked out and 5 types of experience such as sense, feel, think, act, relate of Bernd H. Schmitt was investigated. The spatial composition of drugstores were classified into destination, assortment, convenience and occasion, and through self experienced visual research, the experiential marketing strategy applied to drugstores and the elements of sales promotion applied with experiential marketing was analyzed. The streets of Hongik University as a strategic point of beauty, by selecting four H&B stores which were recently opened, a future direction is proposed by conducting the case analysis on the elements of sales promotion of drugstores and the spatial composition of drugstores applied with experiential marketing. In conclusion, in overall space, the behavioral experiential elements are weak. The behavioral experiential elements are a marketing that induce the intuitive behavior added with expertise and considered difficult to be maintained. Although the consumers think that the biggest value of drugstores is 'free and convenient product test' but in the other hand, they tend to think most positively about the consulting of experts. Therefore, the space emphasized with expertise should be more highlighted but such space should consider the convenience of consumers.

Cerium oxide (ceria, CeO₂) is one of the most wide-spread oxide supporting materials for the precious metal nanoparticle class of heterogeneous catalysts. Because ceria can store and release oxygen ions, it is an essential catalytic component for various oxidation reactions such as CO oxidation (2CO + O₂ 2CO₂). Moreover, reduced ceria is known to be reactive for water activation, which is a critical step for activation of water-gas shift reaction (CO + H₂O → H₂ + CO₂). Here, we apply van der Waals-corrected density functional theory (DFT) calculations combined with U correction to study the mechanism of water chemisorption on CeO₂(111) surfaces. A stoichiometric CeO₂(111) and a defected CeO₂(111) surface showed different water adsorption chemistry, suggesting that defected CeO₂ surfaces with oxygen vacancies are responsible for water binding and activation. An appropriate level of water-ceria chemisorption energy is deduced by vdW-corrected non-local correlation coupled with the optB86b exchange functional, whereas the conventional PBE functional describes weaker water-ceria interactions, which are insufficient to stabilize (chemisorb) water on the ceria surfaces.

본 논문에서는 OFDM(Orthogonal Frequency Division Multiplexing) 시스템에서 사용되는 보호구간을 하드웨어로 효율적으로 구현할 수 있는 기법을 제안하고, OFDM기반의 25 Mbps 무선 ATM 모뎀에 적용하여 ASIC칩을 설계한다. OFDM 시스템에서는 가장 긴 delay spread 보다 긴 cyclic prefix를 삽입하여 채널의 선형 컨볼루션을 이산 Fourier 영역에서 circular 컨볼루션으로 변형함으로써 부채널간의 직교성을 유지하고, OFDM 블록내의 심볼간 간섭은 방지한다. 그러나 OFDM 시스템에서 이러한 cyclic prefix를 사용하기 위해서는 원래 샘플을 저장하고 각 블록의 시작 위치에 cyclic prefix를 붙이기 위한 추가적인 하드웨어가 송신단에서 요구된다. 본 논문에서는 cyclic suffix를 사용한 새로운 기법을 제안하고, 제안된 기법이 기존의 cyclic prefix 기법에 비하여 매우 적은 하드웨어로 동일한 성능을 갖게 됨을 확인한다. 마지막으로 제안된 기법을 OFDM기반의 25 Mbps 무선 ATM 모뎀의 ASIC칩 설계에 적용하여 그 성능을 확인한다.

A superconductor flywheel energy storage system (SFES) is an electro-mechanical battery which transforms electrical energy into mechanical energy for storage, and vice versa. A 35 kWh class SFES module was designed and constructed as part of a 100kWh/1MW class SFES composed of three 35 kWh class SFES modules. The 35 kWh class SFES is composed of a main frame, superconductor bearings, a composite flywheel, a motor/generator, electro-magnetic bearings, and a permanent magnet bearing. The high energy density composite flywheel is levitated by the permanent magnet bearing and superconductor bearings, while being spun by the motor/generator, and the electro-magnetic bearings are activated while passing through the critical speeds. Each of the main components was designed to provide maximum performance within a space-limited compact frame. The 35 kWh class SFES is designed to store 35 kWh, with a 350 kW charge/discharge capacity, in the 8,000 ~ 12,000 rpm operational speed range.
