The process and change of convergence in the economy and industry with the development of digital technology and combining with new technologies is called Digital Transformation. Specifically, it refers to innovating existing businesses and services by utilizing information and communication technologies such as big data analysis, Internet of Things, cloud computing, and artificial intelligence. Digital transformation is changing the shape of business and has a wide impact on businesses and consumers in all industries. Among them, the big data and analytics market is emerging as one of the most important growth drivers of digital transformation. Integrating intelligent data into an existing business is one of the key tasks of digital transformation, and it is important to collect and monitor data and learn from the collected data in order to efficiently operate a data-based business. In developed countries overseas, research on new business models using various data accumulated at the level of government and private companies is being actively conducted. However, although the trade and import/export data collected in the domestic public sector is being accumulated in various types and ranges, the establishment of an analysis and utilization model is still in its infancy. Currently, we are living in an era of massive amounts of big data. We intend to discuss the value of trade big data possessed from the past to the present, and suggest a strategy to activate trade big data for trade digital transformation and a new direction for future trade big data research.

This study aims to investigate the impact of wide use of digital technology, in particular, the Internet, on innovation process and corporate strategy in electronics industry. The introduction of digital technology has changed innovation process, business model and organizational structure of the electronics companies. With the introduction of digital technology, the entire value chain of electronics industry from procurement, sales, and marketing to R&D and manufacturing has been restructured. E-commerce has been a major agenda for e-business. Recently, collaboration among electronics companies through e-marketplace has emerged as an important issue. A web-based e-commerce standard, so called RosettaNet, has been developed for facilitating e-transactions of electronics firms. The development of digital technology has dramatically increased the processing speed and sophisticated the virtual reality technology. As simulation becomes easier and more effective, the uncertainty and risk involved in R&D has decreased significantly. Another positive impact is closer cooperation between R&D and manufacturing functions. Taking advantage of automated and flexible production technology, has a new type of firm, so called, EMS (Electronics Manufacturing Services) emerged, whose strategic focus is on manufacturing only. The EMS can be seen as a kind of innovative organization, that is, a modular organization for production function. Digital technology has made convergence of computer and communication possible at early years but right now the convergence has been accelerated in extensive areas of communication, broadcasting, information appliances, software, contents, and services. Firms' effort for an innovative product and service has been intensified and the competition for a new standard product and service has become severe in electronics industry. Business activities are always realized in a specific organizational context. Accordingly building up innovation-friendly organization has emerged as a critical concern. Due to the striking decrease of transaction cost, a network type of organization has proliferated, and a business function turns into a modular organization. As a whole, digital technology has pushed electronics firms into developing their own business model, which takes consideration of standardization of business platform and their core competency.

This study aimed to investigate bag purchase behaviors according to materialism value. The subjects were 443 male and female adult consumers in their 20s to 50s. The research method was a survey, and the questionnaire consisted of questions on materialism value, bag purchase behaviors, and demographic characteristics. For data analysis, descriptive statistics, Cronbach's α, χ² test, factor analysis, cluster analysis, ANOVA, and Duncan's multiple range test were performed. The results of this study were as follows. First, materialism value was derived from three factors (happiness pursuit, possession-oriented, and success judgment). Second, subjects could be divided into three groups (happiness pursuit group, success judgment pursuit group, and immaterialism group) based on the materialism value variable. Third, the derived groups showed many differences in bag purchase behaviors. The happiness pursuit group considered all bag evaluation criteria factors (practicality, aesthetics, economy, symbolism) and bag purchasing information sources factors (mass media and personal sources) more than other groups, and showed a tendency to prefer select shops and complex shopping malls as bag purchasing places. In addition, the average annual cost and frequency of purchasing bags of this group were higher than those of other groups. The success judgment pursuit group considered symbolism as a bag evaluation criteria more than other groups, and considered personal sources as bag purchasing information sources more than mass media sources, and preferred luxury stores and department stores as bag purchasing places. On the other hand, the immaterialism group considered practicality and aesthetics as bag evaluation criteria and placed less importance on all information sources than other groups, and preferred Internet shopping malls as purchasing places. This group had the lowest average annual purchase cost and frequency among the three consumer groups. This study suggested that materialism value is a useful variable to segment male and female adult consumer markets effectively, and to understand the bag purchase behaviors of consumer groups divided by materialism value.

With the start of the present Korean Creative-Economy Government, more effort is put to prepare the Unification in many areas. But it is not easy to find studies on contemporary status of North Korea specifically in information technology or computer education due to the poor accessibility to the country. This study is on comparing computer education in elementary schools in North Korea and South Korea and diagnosing future direction of computer education as the beginning stage of Unification. The most study is performed from backtracking curriculum methodology based on computer textbooks from North Korea and South Korea. In both countries, the elementary school curriculum for computer subject is mostly dealing with the usage of softwares. In North Korea they don't teach internet applications and they uses different type of office programs. The further ideas for desirable future education are suggested with analysis on the computer education in other countries such as China and Vietnam which can be appropriate role models for North Korea and USA, UK and India for South Korea. It is expected in both countries that the computer education will be more focused on programming rather than on software usage in the future.

Since its market opening in the year 1996, Korea's retail sector has witnessed the emergence of various new retail formats such as discount stores and Internet shopping malls. Given the competition among various retail formats, it is needed to analyze the previous trends and to measure the future potential of the market with more careful economic models. Using Time Series Analysis on Korean economy and distribution industry, we aim to economic models to follow the trends and to measure the future growth of competing retail formats such as department stores, discount stores and convenience stores. We have found that the growth of department stores, convenience stores and specialty store format is very closely related with the private consumption expenditure. On the other hand, private consumption expenditure is not a good variable to explain the growth of discount stores and the supermarket sector. Following an extensive data analysis, three year forecasting of Korean distribution market including six different retail sectors is proposed. In addition, several discussion points including statistical classification of retail formats are argued.

Urban public health monitoring in smart cities focuses on the control of conditions and health challenges in urban environments. Considering the rapid spread of diseases and pandemics, it is important for health authorities to trace people carrying the virus. In smart cities, this tracing must be interoperable and intelligent, especially in indoor surfaces characterized by small distances between people. Therefore, to fight pandemics, it is necessary to start with the already-existing digital equipment of the Internet of Things, such as connected objects and smartphones. In this study, the developed system is employed to provide a social IoT network and suggest a strategy which allows reliable traceability without threatening the privacy of users. This IoT-based system allows respecting the social distance between persons sharing public services in smart cities without applying smartphone applications or severe confinement. It also permits a return to normal life in case of viral pandemic and ensures the much-desired balance between economy and health. The present study analyses previous proposed social distance systems then, unlike these studies, suggests an intelligent and distributed IoT based strategy for positioning students. Two scenarios of static and dynamic optimization-based placement of Bluetooth Low Energy devices are proposed and an experimental study shows the contribution and complementarity of the introduced contact tracing strategy with the applications on smartphones.
