  • Purpose: This study examined a comprehensive model for assessing the success probability of electric vehicle (EV) commercialization in the Korean market. The study identified three risks associated with successful commercialization which were technology, social, policy, environmental, and consumer risk. Research design, methodology: The assessment of the riskiness was represented by a Bayes belief network, where the probability of success at each stage is conditioned on the outcome of the preceding stage. Probability of success in each stage is either dependent on input (i.e., investment) or external factors (i.e., air quality). Initial input stages were defined as the levels of investment in product R&D, battery technology, production facilities and battery charging facilities. Results: Reasonable levels of investment were obtained by expert opinion from industry experts. Also, a survey was carried out with 78 experts consisting of automaker engineers, managers working at EV parts manufacturers, and automobile industry researchers in government think tanks to obtain the conditional probability distributions. Conclusion: The output of the model was the likelihood of success - expressed as the probability of market acceptance - that depended on the various input values. A model is a useful tool for understanding the EV industry as a whole and explaining the likely ramifications of different investment levels.

  • As new types of medical devices are emerging through convergence with advanced technology, innovative technologies are becoming hot issues in health policy because of their disruptiveness. This study analyzed the innovative medical device management systems in the US, China and Korea. Innovative medical devices have been defined differently depending on the country's management system, but in common, they are defined as products that do not exist or have dramatically improved performance compare to existing products by applying innovative technologies. Innovative medical devices have been supported by regulatory authorities during product development and approval processes. While the US and China have more than 300 products designated as innovative medical devices with diverse functions, application fields, and manufacturing countries considering the initial situation of the implementation for the system, Korea has only 16 products, mainly radiology and diagnostic devices and made in Korea only as innovative medical device. In addition, Korea shows the highest market approval rate of innovative medical devices compare to the US and China, and it is necessary to prepare the approval process in consideration of product diversity.

  • This paper aims to develop a prediction model for the product quality of a casting process. Prediction of the product quality utilizes an artificial neural network (ANN) in order to renovate the manufacturing technology of the root industry. Various aspects of the research on the prediction algorithm for the casting process using an ANN have been investigated. First, the key process parameters have been selected by means of a statistics analysis of the process data. Then, the optimal number of the layers and neurons in the ANN structure is established. Next, feed-forward back propagation and the Levenberg-Marquardt algorithm are selected to be used for training. Simulation of the predicted product quality shows that the prediction is accurate. Finally, the proposed method shows that use of the ANN can be an effective tool for predicting the results of the casting process.

  • This study is based on the utilization of pine mushroom for processing products by development of pine mushroom Jung-Gwa. The results were summarized as follows: Pine mushroom Jung-Gwa were prepared with four different amounts (20, 30, 40, 50%) of honey. Pine mushroom Jung-Gwa color value was the highest by 20% soaking honey-water product and 40% soaking honey-water product was the lowest. Strength and hardness of 20% soaking honey-water product was the highest. Appearance to product of 50% soaking honey-water was the highest preference by all age of except 20's. The honey content of more and more external appearance preference was became higher. Product of 40% soaking honey-water was best by flavor of pine mushroom Jung-Gwa. A sugary tastes comparison 50% soaking honey water to 40% soaking honey water was not distinction. The texture was appeared a statistically significant difference by products of 20%, 30% soaking honey-water. Product of 20% soaking honey-water was favorite in 20's and product of 30% soaking honey-water was favorite in 30's. In overall preference test for pine mushroom Jung-Gwa of 40% soaking honey water was preferred by all age. Oligosaccharide helped geriatric diseases and cheaper. Thus this study used oligosaccharide but the result was not a statistically significant difference of pine mushroom Jung-Gwa products quality by comparison honey-water to oligosaccharide. Therefore oligosaccharide utilization products was thought worth a lot more by processing price and functional.

  • This paper analyses characteristics of the numerical controller industry in market formation and the flow of information between users and producers and the characteristic of knowledge base of the industry and discuses the difficulties derived, from the characteristics, in accumulation of technological capability. In market formation between users and producers, the multi-layered market is not favorable to domestic producers in that lower end market is not large enough to provide cradle market to them which produce inferior quality and lower price than imported products. The credibility of the performance of a product is different to prove until a critical mass of products are sold. Therefore gaining market share is deterred by unproven credibility of the performance of the product. The flow of information between users and producers is limited. The flow of information on users environment through mass market to producers is essential for improving credibility of a product. The nature of knowledge base is tacit and the means of knowledge transmission is limited. Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. This paper argues that these characteristics of the industry challenge existing approach to R&D management and framework of science and technology policy.

Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. It is conjectured that these characteristics are derived from the fact that the numerical controller is the result of IT based technological convergence in controlling machining process. This paper argues that these characteristics of the industry challenges existing approach to R&D management and framework of science and technology Policy.

  • In addition to simply providing quality food to the people, the fishery industry must be maintained and developed because it has various functions such as national food security, preservation of natural scenery, protection of national territory, and revitalization of the local economy. However, risk factors such as climate changes and environmental destruction have raised concerns about the sustainable development of the industry. Since these risk factors are becoming larger and more complex over time, it is time to conduct research related to the risk of the fishery industry. Therefore, the purpose of this study is to explore the risk factors facing the fisheries at this point, to analyze the economic ripple effect of regional fishery product supply shortage, and to draw implications. As a result of this study, the economic ripple effect of fishery product shortage per won was highest in Busan, followed by Gangwon, Gyeongnam, and Gyeongbuk. Considering the size of the local fishery industry, Busan had the highest supply shortage per 1% of local fisheries production. It is also necessary to prepare special risk management and countermeasures for these regions since the effect of supply shortage in regions such as Jeonnam, Gyeongnam, and Jeju is large compared to other regions.

  • Objective: Service industry has become the most important industry among various economic activities, as the percentage of service related industry in advanced nations is over 60% of their GDP and the percentage of service industry in South Korea, a traditional manufacturing nation, now takes up over 60% of the entire economy. Background: Such industry paradigm shift has changed consumers from those that simply purchased products into groups of people that evaluate the companies that manufacture products, thereby further intensifying competition among companies and increasing the importance of integrated communication between companies and consumers. However, the excessive existence of sub-identities that have been developed for integrated management of the existing corporate identities, as well as the undifferentiated general management strategies by companies are creating confusion not only for consumers but also for various corporate interest parties. In addition, service identity strategy has become the most important strategy than any other sub-identity strategies in forming corporate identity at the increased importance of corporate service in the era of service industry. However, the current domestic circumstance is that the concept of service identity has not been well established through specific related studies. Method: Accordingly, the existing academic and field studies on the corporate identity(CI), brand identity(BI) and product identity(PI) used for the communication with consumers were reviewed in this study to establish and summarize the concept of service identity(SI) that appeared at the service economization. Results: The purpose is to examine the kind of change that could be brought about by SI for the corporate integrated identity strategy developed through the existing corporate, brand & product image in order to present a new direct in corporate identity strategy according to the industry paradigm shift through a SI centered new corporate identity framework. Conclusion: For preparing the new era of service industry, the corporate integrated identity strategy must be integrate with concept of service identity and which is essential to differential from other companies. Application: The proposed concept and framework of service identity on this paper will help to understand and clearly define why service identity is important factor of the new idea of corporate identities.
