Distribution and logistics industries contribute some of the biggest GDP(gross domestic product) in South Korea and the number of related companies are quarter of the total number of industries in the country. The number of retail tech companies are quickly increased due to the acceleration of the online and untact shopping trend. Furthermore, major distribution and logistics companies try to achieve integrated data management with the fulfillment process. In contrast, small and medium distribution companies still lack of the capacity and ability to develop digital innovation and smartization. Therefore, in this paper, a deep learning-based demand forecasting & recommendation model is proposed to improve business competitiveness. The proposed model is developed based on real sales transaction data to predict future demand for each product. The proposed model consists of six deep learning models, which are MLP(multi-layers perception), CNN(convolution neural network), RNN(recurrent neural network), LSTM(long short term memory), Conv1D-BiLSTM(convolution-long short term memory) for demand forecasting and collaborative filtering for the recommendation. Each model provides the best prediction result for each product and recommendation model can recommend best sales product among companies own sales list as well as competitor's item list. The proposed demand forecasting model is expected to improve the competitiveness of the small and medium-sized distribution and logistics industry.

This paper examines critical successful facts related with the digital new product development with product innovation. For this, we have selected a Xcanvas time-machine TV of LG electronics and we have done case-study. We have performed in-depth interviews with engineers, team managers, marketers to get facts on the product development process and analyzed huge amount of data obtained from web-sites and related firms' materials. We have concluded that CSFs of Xcanvas time-machine TV are customer-centered product innovation, new perspective of considering technology and product, managing innovative team and motivation to team member.

The change of digital convergence service environment converted the subject of design into user -centric one instead of developer-centric one, and changed the existing design environment focused on product development into the new user -centric design environment. Accordingly, GUI considering user's usability come to take big shares in those contents being used for multimedia equipments. However, as the present educational contents provide complex interface due to its design produced based on the existing e-learning system, they have many problems in that they don't consider user's usability. Thus this paper aimed to analyze actual examples through GUI elements of educational contents being used for multimedia equipments and attempt to suggest some directions for development. additionally, consider the various characteristics of digital convergence environment and educational contents, and try to set up strategic directions possible to utilize user'-centric interface elements more usefully and properly at the time to produce designs.

This study identifies the concept of a digital convergence paradigm, which deals with the relationship among convergence and consumer participation, digital contents services, and the culture of consumption (web 2.0). This research was conducted using a quantitative method involving focus group interviews (FGI) and literature reviews. This research examines the relationship between convergence and consumer participation and the adoption of a concept of "convergence culture", which is categorized as "collective intelligence" and "intellectual community participation". The role of the consumer has changed from one of a "consuming consumer" to that of a "collaborating consumer" and finally to the concept of a consumers as the originator of a new consumption culture. In the study, the consumption culture of web participants indicated the characteristics of funology, self-expression, life-catching, quick-tempered, immersion(arousal), sharing culture, multitasking, and cyber justice. The recognition level of networking on the "digital convergence" of the consumer was identified as that of the combination of IT(information technology); product and multi-services or alliance of industry groups(telecom, broadband, IPTV service); or the use of one source with multiple devices.

This study examines the actual state of using digital convergence products by consumers, and analyzes the expectation that consumers have regarding digital convergence products and the actual satisfaction of the digital convergence products. In addition, it analyzes factors affecting the satisfaction with digital convergence products. First, mobile phones, which 99.4% of those surveyed had, cameras, which 90.6% had, and mp3s, which 71.8% had, were found to be necessities. Second, the ratio of owning digital convergence products was 79.5%, 48.1%, and 52.4%, respectively. In the case of a mobile phones, a digital convergence type is already common. Third, regarding the reason for purchasing digital convergence products, they chose convergence products because there was no product with a simple function that they wanted to have: 38.2% in terms of a mobile phone, 47.2% for a camera, and 28.2% for an mp3. This shows that a consumer's choice was infringed in a great deal at the back of remarkable quantitative growth in digital convergence products. Fourth, the analysis of the factor regarding the consumer's expectation on digital convergence products showed 3 kinds of factors, i.e., expectation of benefit, expectation of risk, and expectation of situation. Fifth, as a result of analyzing the structural model regarding the effect on satisfaction by a consumer's expectation and the outcome on digital convergence products, all the expectations and outcomes of benefit, risk, and situation did not have a direct effect on satisfaction. Only an indirect effect through inconsistency showed a statistical significance.

This study aims to examine the effects of on premium convergence products buying behavior. This paper analyzed the positive attitude formation using the basic and extended TAM and also revealed how the positive premium convergence product attitude relate to relationship purchasing intention and word of mouth intention. The samples of 562 consumer indicate that the antecedents are consist of four dimension(perceived usefulness, perceived ease of use, social value) and attitude is developed into buying intention and word of mouth intention. We have reached the following conclusion about the antecedents and outcomes factors of customer attitude for the launch of premium convergence product. First, perceived usefulness, perceived delight, and social value had a positive effect on customer attitude but perceived ease of use did not. Second, we found that customer attitude had a positive effect on purchase intention and word-of mouth intention. Finally, interaction effect of perceived usefulness/perceived delight and social value had a positive effect on customer attitude. Our findings suggested that adoptian and diffusion of premium convergence product is influenced by several behavior factors. Managerially, our result emphasize that premium convergence products must satisfy not only the perceived usefulness/delight but also social value that consumers are seeking in order to be successful in the market. The theoretical and practical implications of these findings are discussed as well.
