Because of governmental regulations, large-scale discount stores are trying to find a new way that can expand a market size. Homeplus virtual store has received attention from the other companies, because virtual store can access 24 hours and be unfettered by governmental regulations. The purpose of the study is to review performance and strategies of Homeplus virtual store as well as the cause of the failure of imitators. To do this, we can find key indicators of success of virtual store.

Smart phone environment have an effect on consumer life style, as well as advances in technology. In this paradigm shift on digital convergence make change to commodities, services, and distribution channels for consumers. HomePlus wholesale that is representative distribution company in Korea launched the new distribution channel model that combined off-line store with online store and mobile shopping system called 'smart mobile virtual store'. That is highly praised by abroad media and festivals. This study is an exploratory study on consumer-centric smart mobile virtual store of HomePlus. There are value and chance for developing the new digital distribution model, in this study, because the case study and evaluation of consumers is important in this momentous time.

최근 모바일 기기가 활성화되면서 자바스크립트의 성능 향상이 이슈가 되고 있다. 적시 컴파일러를 탑재한 자바스크립트 엔진들이 등장하면서 이러한 요구를 충족하고 있다. 대표적 웹 브라우징 엔진인 WebKit의 자바스크립트 엔진인 SquirrelFish Extreme(SFX)는 콘텍스트 쓰레딩 방식의 적시 컴파일러를 사용하고 있다. 하지만 모바일 환경에서의 성능은 여전히 문제가 된다. 모바일 환경에서 많이 사용되는 ARM CPU를 위한 SFX의 적시 컴파일러는 가상 레지스터를 머신 코드에서 사용하기 위해 많은 수의 메모리 로드와 스토어를 사용하고 있다. 또한 ARM 아키텍처가 제공하는 레지스터를 제대로 사용하지 못하고 사용되지 않는 레지스터가 존재하고 있다. 사용되지 않는 레지스터를 활용하여 메모리 로드와 스토어를 줄이는 레지스터 프로모션을 적용하였다. 루프에서 머신 코드로 수행되는 바이트 코드를 중심으로 가상레지스터를 실제 머신 레지스터로 할당하여 메모리 로드와 스토어를 줄이고 일부 벤치마크에서 성능향상이 나타남을 확인 했다. 레지스터 프로모션의 효과를 더 증대하기 위해 레지스터 프로모션의 범위를 함수 전체로 넓히고 핸들러 함수 호출에서 발생하는 오버헤드를 줄이는 최적화가 필요할 것으로 보인다.

This study investigates the effect of service ubiquity perceptions on consumers' responses to virtual stores such as benefit and risk perceptions, shopping value perceptions, and service usage intention. Data were collected via a self-administered online survey from nationwide consumer panels of an online marketing research firm. Questionnaire items were adopted from previous literature and developed by authors via pretesting to measure variables. The results revealed that virtual store service ubiquity affects consumer benefit perceptions as well as risk perceptions. All benefit perceptions (including time effectiveness, user control, and compatibility) had significant mediating effects between service ubiquity and hedonic/utilitarian shopping service value perceptions. The mediating effect of financial risk was significant only in the relationship between service ubiquity and utilitarian value perception. The findings offer retailers and marketers information in regards to consumers' perception of a virtual store usage, which can enhance service and product strategy.

In recent times, more fashion brands have been seeking ways to use metaverse platforms, in which users can actively participate, as their new brand touch-points. This study aims to compare the brand experiences of the fashion brand Gentle Monster's offline store and its equivalent metaverse store. By changing the order of offline and metaverse visits, two groups participated in the field study that allowed them to experience directly the offline and metaverse stores. As a result of the analysis, the following findings were discovered: (1) In the overall experiential response, the frequency of sensory modules responding to new information was much higher than that of feeling experiences; (2) Experiential responses were more active in the offline store where the subjects could touch and use products directly rather than in the metaverse; (3) Among the four types of theme space, the experiential response was the most frequent in the product space; (4) The first group that visited the metaverse store before the offline store showed a more active experience than the second group that visited the offline store first. Finally, the results of this study show that metaverse brand stores in virtual space not only provide differentiated experiences beyond the spatiotemporal constraints of real space but can also be used as a strategic tool to make offline store experiences more meaningful and rich.

This study focused on the difference between Oculus Store of Oculus and FXGEARs. NOON VR Stores service platform. First the literature study considered the current status and prospect of the VR market and conducted a case study on the VR service platform. In addition, this study conducts the platform strategies of Andrei Hakgu and Hirano AtsushI. After that Interviewers were interviewed to investigate the usability of the VR service platforms. The result of this study is expected to be used as a design guideline to form a VR service platform in the future, and as a user experience study.

This study is a study that analyzes the user experience of a virtual makeup application in the beauty industry where color or formulation testing is important. Recently, cases of beauty smart stores and beauty applications using AR and AI are increasing. However, since virtual makeup is different from testing a real product, it is necessary to derive needs through research from the user's side. In order to compare user preferences by using AR and AI cases, six factors based on the emotional interface model were analyzed through a questionnaire to identify items with statistically significant figures. As a result, the user felt comfortable with the virtual makeup function, but showed that it needs to be supplemented in terms of reliability. Since this study focused on the customer experience as a real user and identified the main experience factors and needs of virtual makeup through two types of comparison, it is hoped that this study will be useful as a prior study.

The growth of virtual reality games and the popularization of blockchain technology are bringing significant changes to the formation of the metaverse industry ecosystem. Especially, after Meta acquired Oculus, a VR device and application company, the growth of VR-based metaverse services is accelerating. In this study, the concept that supports leisure activities in the metaverse environment is explored realting to game-like features in VR apps, which differentiates traditional mobile apps based on a smart phone device. Using exploratory text mining methods and network analysis approches, 241 apps registed in the Oculus Quest 2 App Store were analyzed. Analysis results from a quasi-network show that a leisure concept is closely related to various genre features including a game and tourism. Additionally, the anlaysis results of G & F model indicate that the leisure concept is distictive in the view of gateway brokerage role. Those results were also confirmed in LDA topic modeling analysis.

In this study, based on the general reasoning that the higher the resolution of the HMD, the greater the presence and immersion of the audience and the greater the presence experience, the difference in the presence experience according to the resolution of the virtual reality device is verified empirically Presence effect. To do this, 300 college students were included in the population, and VR simulations of the Oculus store were conducted using HMD and mobile devices with different resolutions (HD, FHD, WQHD) as stimuli. As a result, there was a significant difference in the presence experience of the audience according to the resolution of the mobile device attached to the virtual reality HMD, and the presence effect had a significant influence on the awakening. On the other hand, no significant influence was found in the effect of emotion. Therefore, we can prove a general reasoning hypothesis that the higher the resolution of the virtual reality device, the greater the presence experience of the audience. However, since the confounding effect and the impression are contradictory in the presence effect side, additional experiments research is required.
