Recently, as the online market has matured, it is facing many problems to prevent the growth. The most common problem is the homogenization of online products, which fails to increase the number of customers any more. Moreover, although the portion of the online market has increased significantly, it now becomes essential to expand offline for further development. In response, many online firms have recently sought to expand their businesses and marketing channels by securing offline spaces that can complement the limitations of online platforms, on top of their existing advantages of online channels. Based on their competitive advantage in terms of analyzing large volumes of customer data utilizing information technologies (e.g., big data and artificial intelligence), they are reinforcing their offline influence as well through this online for offline (O4O) business model. On the other hand, most of the existing research has primarily focused on online to offline (O2O) business model, and there is still a lack of research on O4O business models, which have been actively attempted in various industrial fields in recent years. Since a few of O4O-related studies have been conducted only in an experience marketing setting following a case study method, it is critical to conduct an empirical study on O4O selection attributes and their impact on customer satisfaction and loyalty. Therefore, focusing on China’s representative O4O business model, ‘Fresh Hema,’ this study attempts to identify some key selection attributes specialized for O4O services from the customers’ viewpoint and examine the impact of these attributes on customer satisfaction and loyalty. The results of the structural equation modeling (SEM) with 300 O4O (Fresh Hema) experienced customers, reveal that, out of seven O4O selection attributes, four (mobile app quality, mobile payment, product quality, and store facilities) have an impact on customer satisfaction, which also leads to customer loyalty (reuse intention, recommendation intention, and brand attachment). This study would help managers in an O4O area well adapt to rapidly changing customer needs and provide them with some guidelines for enhancing both customer satisfaction and loyalty by allocating more resources to more significant selection attributes, rather than less significant ones.

Growth mechanism of GS-MBE(Gas source-Molecular Beam Epitaxy) has been investigated. We observed that the growth rate of GaN films is changing from 520 nm/h to 440 nm/h by the variation of V/III ratio under nitrogen-rich growth condition. It was explained that the amount of hydrogen on the growth front varies by the ammonia flow, and gallium hydrides are generated on the surface by a reaction of hydrogen and gallium, resultantly the amount of gallium supplying is changing along with the $NH_3$ flow. Reflection high energy electron diffraction (RHEED) observation was used to confirm the N-rich condition. The crystal quality of GaN was estimated by photoluminescence (PL) and X-ray diffraction (XRD).

다이아몬드와는 달리 CBN은 철족 재료 연삭시 화학적 마모가 거의 없다. 이러한 장점으로 인해 CBN휠이 철강 재료 연삭에 널리 사용되고 잇는 것이다. 그러나 CBN 휠의 성능은 CBN을 붙잡고 있는 결합제에 크게 의존한다. 오늘날 널리 사용되는 결합제인 주석 청동 합금은 내마모성에 한계가 있다. 주석 청동 합금의 내마모성을 증대시키기 위해 Co를 첨가하였다. 이러한 기지합금에 젖음성을 향사시키기위해 Co코팅 CBN을 사용하였다. 기지합금에 20%co를 첨가한 것이 입계에서 연속적인 $\delta$상생성, 취성 증가에 따라 자생작용이 활발하였다. 가장 높은 연삭비를 나타낸 것은 Cu-15wt%Sn, cu-33wt%Sn, co를 40:40:20으로 제작한 휠이었다.
