Digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. In 2011, The Government introduced "IT Convergence Technology Prediction Survey 2025". Smart mobility is a main factor in smart city which is main example of convergence. A intelligent transport system(ITS) is a key factor of smart mobility. The conventional transport systems include road, car, signal systems. But the ITS is a transport system containing additional technologies such as electronics, control, communication to increase traffic safety and effectiveness of traffic facilities. In this paper, we described intelligent transport system related with our life.

This study aims to conduct product design class using scamper technique and to verify its creative effectiveness. Therefore, this study conducted a product design class using SCAMPER to 52 students in the second year of specialized high school, analyzed the results, and verified the effectiveness of idea generation through SCAMPER with a survey. As a result, most of the students used the 'combine' and 'modify' techniques most often to combine other products with existing products or to find and correct problems of existing products. Second, when using SCAMPER, 'flexibility' and 'reconstruction' were used among the creative components. It turned out to provide the ability to see objects from a new perspective. Third, the results of the post-class survey showed that students' satisfaction with the class using SCAMPER was high, which helped them to develop creative ideas.

In the recent business environment, purchase patterns are changing around the influence of COVID-19 and the online market. This study analyzed cluster and correlation analysis based on purchase and product information. The cluster analysis of new methods was attempted by creating customer, product, and cross-bonding clusters. The cross-bonding cluster analysis was performed based on the results of each cluster analysis. As a result of the correlation analysis, it was analyzed that more association rules were derived from a cross-bonding cluster, and the overlap rate was less. The cross-bonding cluster was found to be highly efficient. The cross-bonding cluster is the most suitable model for recommending products according to customer needs. The cross-bonding cluster model can save time and provide useful information to consumers. It is expected to bring positive effects such as increasing sales for the company.

Recently, the e-business market has become a place of convergence where consumers and suppliers communicate with each other, and a new method of trading of funds has emerged in the process. Crowd-funding is one of the types of money transactions that have emerged in the online space, and its interest and trading volume have been growing rapidly recently. The platform in the online space using crowd-funding method operates in the form of online telecommunication sales, and it is in the form of producing and delivering products based on funds obtained from potential consumers by the operators involved in securing funds. However, if the participating business operators do not deliver the product or deliver the product other than the promoted product and avoid responsibility, the potential demander will not be compensated without mediation by the platform operating entity. In this study, despite the rapid growth in the market size of crowd-funding, consumers who participated in the funding are protected and able to resolve disputes in the event of a conflict amid growing complaints from potential consumers and side effects. The structure or method of crowd-funding is a new form of trading that has different features from conventional e-commerce. Therefore, the legal basis is not yet in place and the standards need to be laid out through various and sufficient discussions politically, legally, socially and culturally and economically. As the potential market and positive effects of crowd-funding around the world have been recognized, a role is required as an ecosystem for new financial transactions. And the potential market could be realized as a new industry if the right legal system and policy consultation were made.

Remanufacturing is one of the most important resource recycling technology in response to resource depletion and environmental pollution. Domestic remanufacturing industry don't invigorate compared to other advanced countries because of low price and reliability of remanufactured product. In this study, remanufactured hydraulic pump and solenoid valve were evaluated durability by accelerated life test. In order that standard remanufacturing process was developed by core analysis and failure mode and effect analysis. And cores were remanufactured by standard remanufacturing process. For accelerated life test, the evaluation item and criteria were deduced by results of FMEA, reliability standards and enterprise interior criteria. To evaluate durability of remanufactured product, the remanufactured hydraulic pump and solenoid valve were evaluated performance after accelerated life test and the results were satisfied with criteria. This study showed that remanufactured products have a similar level of durability to new products by definition of remanufacturing.

This study presents "Indispensability" and "Irreplaceability" as new variables for studying the attachment process of digital products that are different from physical products. To analyze this quantitatively, we will set up an integrated model to explore how attachment can be formed through different product-user interactions and time value which are necessary for attachment formation. Analysis of 197 respondents' data for empirical analysis showed that system-centric interactions did not affect the duration of use, whereas user-centric interactions affected the duration of use. In addition, the effects of the period of use on the Indispensability and the Irreplaceability were demonstrated, and the effects on the Indispensability were greater than Irreplaceability.

As social distancing strengthened after the COVID-19 incident, people looked for things they could do alone. Additionally, as people have more financial resources, they purchase products they had previously considered purchasing, and the phenomenon of giving gifts to oneself has also appeared. Accordingly, this study analyzed fashion product reviews of KakaoTalk Gift, the service to exchange gift via SNS mobile app, to discover the phenomenon of self-gifting and the differences from interpersonal-gifting. For post-hoc data, in collected 18,354 pieces after excluding unnecessary data using a Python-based web crawling technique. The self-gifting behavior of KakaoTalk Gift different from the previous study for self-gift. Regardless of the gift-giving contexts, it determines that most self-gift products are material items. There are differences in product types and price levels when choosing gifts for others and oneself. As a self-gift, people typically buy luxury jewelry and branded bags/wallets to wear and show off. As interpersonal, among fashion products, people usually buy beauty products that reflect less personal tastes. When gift-giving to others, people buy products to appropriate prices to reduce the burden on both. When gift-giving to oneself, people buy wanted products regardless of the price. This study is significant because it suggests a new direction in self-gift research by limited online places to give gifts.

The purpose of this study is to investigate the problems of the rapidly increasing voice interface and to find out what results will be obtained when the new gesture interaction is applied to the product, and to suggest the improvement method for a better user experience. Through the literature review, I have conducted a theoretical review on the changes in the product interface used in the product and the difference between them, and then conducted in-depth interviews on the 20-30 users who used voice recognition as a product trigger. As a result, it was concluded that the decline in the reliability of accuracy leads to a decrease in the preference of voice recognition interactions and an needs of appropriate interface for the functional aspect of non-relavancy in physical distance as a product trigger. This study is meaningful in that it has found a problem with the study of the product trigger interface and suggested improvement measures, and hope to be helpful in follow-up study.

This study testified the influence factors like quantities of advertising, number of hardware and software that are converged, effect on feature fatigue of convergence product. When consumers perceive higher numbers of hardwares in a smart phone, they feel its higher usefulness and complexity. This means that numbers of hardwares is the major factor that enhances consumer's usefulness but, at the same time, it cause perceived leads to higher usefulness in using smart phone, it didn't effect on complexities. It is also important strategy for smart phone companies to provide a lot of useful softwares(applications) to satisfy consumers. Finally, complexity was important factor that lead to higher feature fatigue of consumers. This indicates that smart phone companies have to find adequate numbers of convergence for their new smart phone.
