The aim of this study is to find the key elements for the successful introduction of a Cyber University (CU) in Korea. Since information technology (IT) has dramatically changed our lives it is inevitable for education to follow suit. The old education system was based on the following principle, of a teacher physically interacting with his or her pupils at a school. However, this is set to become infinitely more flexible with the freedom of choice given to the pupil who are now able to adopt, beyond barriers of time and space what, and how they study. All this will be made possible with the use of IT. The essentials for the CU would be a positive and flexible education paradigm, also able to satisfy students with a totally new system of education that replaces physical interaction with virtual interaction. Another point that needs to be taken into account is the number of potential students, their expectations and needs. And any national or international restrictions need to be addressed. One major hurdle for the acceptance of a CU in Korea is the vast difference between its conservative culture and directness of Western culture. Despite this, it will soon become imperative for Korea that she embraces the rapidly changing attitudes and requirements in order for the survival of the nation and an individual.

The introduction of virtual power plants is actively being discussed to solve the problem of grid acceptability caused by the spread of distributed renewable energy, which is the key to achieving carbon neutrality. However, a new business such as virtual power plants is difficult to secure economic feasibility at the initial stage of introduction because it is common that there is no compensation mechanism. Therefore, appropriate support including subsidy is required at the early stage. But, it is generally difficult to obtain the cost model to determine the subsidy level because of the lack of enough data for the new business model. In this study, a survey of domestic experts on the requirements, appropriate scale, and cost required for the introduction of virtual power plants is conducted. First, resource composition scenarios are designed from the survey results to consider the impact of the resource composition on the cost. Then, the cost estimation model is obtained using the individual cost estimation data for their resource compositions using logistic regression analysis. In the case study, appropriate initial subsidy levels are analyzed and compared for the virtual power plants on the scale of 20-500MW. The results show that mid-to-large resource composition cases show 29-51% lower cost than small-to-large resource composition cases.

Concept of Open Innovation (OI) has recently prevailed in academia and industry as a model for increase in R&D productivity. This concept which in turn leads to an improvement in R&D investment efficiency has therefore drawn many firms to adopt this new model. And this has been the same for Korean firms since the extensive introduction of the OI concept in the early 2009. Yet, the problem with this is that the Korean firms do not know much about this concept in practice: what causes OI to occur, what the intended purpose of its introduction is, what proper procedures to take for a successful introduction, and so on. Based on LG Chem’s Open Innovation movement case which ignited in the late 2006, this paper answers the questions previously raised. The successful introduction was made possible by taking a proper procedure of change management along with a strong support from its senior management. This paper also identifies how the OI movement, which was a way to introduce new technology from the outside, has acted as a catalyst in forming a cooperative R&D atmosphere in LG Chem, and how the role of OI has transformed into a strategic tool for organization change.

Along with technological innovation, successful market entry of a new product is important for sustainable innovation of a firm. In this paper, we examined factors that affect successful introduction of new branded drugs in pharmaceutical industry. Under competing theories of the first mover's advantage and the late mover's advantage, this research focuses on how latecomers can overcome the disadvantages of late entry and catch up to the market leader. First, late movers can absorb the knowledge leaked from pioneering product during the time lag between early entrants and late entrants. Therefore, the time lag provides late entrants an opportunity to catch-up to market leader by differentiating and improving the quality of new product. Second, superior marketing capability of late entrants can enhance the possibility of catching-up, by overcoming the consumer base of early entrants.

Prior research in R8ED innovation in Korea has been centered around the 'three-stage development model,' which hypothesizes that the Korean innovation process goes from the introduction (of foreign technology) stage, through assimilation stage to the final modification stage. As Korean economy shifts from traditional industry-led development to innovation-centric development, such an approach loses sight of the whole picture. The current study argues that a new framework is required for adequate analysis on newly arising innovative patterns in Korea, emphasizing source technology development and technology leader strategy. For this purpose, we propose the 'Jigsaw Puzzle Model' of technology development, which is then verified by an in-depth analysis on the innovation processes of 3 representative IT products of Korea, DRAM, TH LCD, and CDMA. The model suggests that Korean innovation model is a dynamic, efficient amalgamation of foreign-acquired and dependent technologies, based on internally accumulated technological resources. The model explains better how Korean firms are achieving a rapid catch-up of technological gaps with advanced nations and are able to transfer from the technology follower to the leader position.

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 wide use of digital technology, the entire value chain of electronics industry from procurement, sales, and marketing to R&D and manufacturing has been restructured. This paper examine how digital technology has changed firms' behaviors in various areas through e-commerce, virtual reality and simulation, the rise of a new type of firm called EMS (Electronics Manufacturing Services), and etc. Amidst these changes building up innovation-friendly organization has emerged as a critical concern for firms. 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.
