  • Large workspace and strong grasping force are required when a robot manipulates big and/or heavy objects. In that situation, bimanual manipulation is more useful than unimanual manipulation. However, the control of both hands to manipulate an object requires a more complex model compared to unimanual manipulation. Learning by human demonstration is a useful technique for a robot to learn a model. In this paper, we propose an imitation learning method of bimanual object manipulation by human demonstrations. For robust imitation of bimanual object manipulation, movement trajectories of two hands are encoded as a movement trajectory of the object and a force trajectory to grasp the object. The movement trajectory of the object is modeled by using the framework of dynamic movement primitives, which represent demonstrated movements with a set of goal-directed dynamic equations. The force trajectory to grasp an object is also modeled as a dynamic equation with an adjustable force term. These equations have an adjustable force term, where locally weighted regression and multiple linear regression methods are employed, to imitate complex non-linear movements of human demonstrations. In order to show the effectiveness our proposed method, a movement skill of pick-and-place in simulation environment is shown.

  • The purpose of this study is to research the conspicuous consumption characteristic expressed in the modern fashion. The conspicuous consumptions are classified with 2 parts as follows as: 1. The motive of conspicuous consumption, 2. The effect of conspicuous consumption. And the motive of conspicuous consumption is 1) conspicuous consumption, 2) conformity consumption, 3) compensatory consumption. The effect of conspicuous consumption is 1) veblen effect, 2) bandwagon effect, 3) snob effect. The veblen effect is caused either by the belief that higher price means higher quality, or by the desire for conspicuous consumption to be seen as buying an expensive, prestige item. The bandwagon effect is people tend to follow the crowd without examining the merits of a particular thing. The snob effect refers to the desire to own unusual, expensive or unique goods. The conspicuous consumption has produced conflicting results of the homogeneous imitation and the different scarcity. Consequently conspicuous consumption characteristic expressed in the modern fashion refers to the conformable imitation and the different scarcity. The conformable imitation is pursuit of first lady look and imitation. The different scarcity refers to the desire to own exclusive or unique goods. The unique value is pursuit of limited edition and art mode.

  • It is the juristocracy in architecture to judge the architectural plagiarism by copyright law. The architectural plagiarism should judge by architectural criticism. From the point of the criticism to discuss architectural plagiarism, the study on artistic imitation should be preceding. The current discussion on architectural plagiarism doesn't consider artistic imitation. Therefore, the result of the discussion only focused on whether the building is plagiarizing or not. From the point of architectural criticism, there should be three considerations, which are creation, imitation, and plagiarism. In the study of Aesthetics, it theorized artistic imitation as the appropriation. With the understanding of the appropriation, contemporary art is developing the discourse on plagiarism beyond the boundary of plagiarism fundamentalism. The purpose of this study is to apply the appropriation to the discussion of architectural plagiarism. The study introduces the discourse on architectural plagiarism rather than judging it with copyright law. There so the study categorized the aesthetics standard of appropriation art, then apply it to the architecture cases. The architecture cases subjects of analysis are the glasshouse by Philip Johnson, National Museum of Australia by Howard Raggatt, and the Meiquan 22nd Century in China. At the point of the appropriation theory, the glasshouse is the only architectural appropriation, and others need to apply the evaluation criteria of plagiarism.

  • In this study, we tried to represent representative animals in traditional dance and study about cultural symbolic representations that symbolize them, thus meaning Korean worship of animal worship and philosophy of life and discuss the identity of Korean traditional art. This is to ask fundamental questions about Korean culture and art, and to express the cultural philosophical reason for the representation of animal imitation. Therefore, Korean animal imitation dance was able to get a glimpse of Koreans' recognition of artistic value which is reflected in dance beyond simple cultural code. In other words, it was found that not only magic and sexual metaphors but also the adaptive attitude through natural friendly life and the ethical practice in reality were inspired by artistic aesthetics.

  • Previous studies indicate that information and communication technology (ICT) adoption is affected by innovation influence such as usefulness, ease of use and self-efficacy. Most of these studies, how-ever, bypassed imitation influence such as subjective norms, word-of-mouth, and advertising, specifically, interactive innovation having critical mass in technology acceptance research. Thus, this study focuses to investigate imitation influence in individual adoption of mobile communication technology. The purpose of this study is to empirically examine the causal relationships between initial acceptance and the intention to use in terms of a holistic approach. The results of this study show that there is an imitation influence including word-of-mouth and subjective norms, from the prior adopters to potential adopters, and mass advertising through TV or news-paper commercials in the ICT diffusion process. In addition, this imitation influence also stimulates innovation influence such as perceived usefulness. Finally, this study provides a set of guidelines to mobile communication equipment manufacturers and ICT vendors in developing effective strategies for technology diffusion.

  • Purpose - The purpose of this study is to examine the viability of imitation strategy. Imitation strategy is one of the strategic options that a late mover can choose, and by selecting the strategy, the company imitates key elements of the business model of first movers, and modifies them to suit its conditions. The author attempted to explain how the elements of first mover's business models were creatively adapted to suit the conditions of late movers so that they can secure market position face-to-face market leaders. Research design, data, and methodology - For the purpose of the study, Korean coffee franchise industry was selected to compare the strategies of first and late movers and to discuss imitation strategy in detail. The author conducted in-depth case study of first mover and business model innovator Starbucks and Ediya Coffee, one of their imitators. The paper examines how Ediya has imitated and modified the business model of Starbucks to secure its unique competitive position in domestic market by using value chain and generic strategy analysis. Results - Starbucks and Ediya were compared in terms of their interior design, the price level of beverages, the variety of side dishes, and shop locations. Starbucks have invested interior design heavily to shops, offered diverse beverages and side dishes with relatively high price, the shops are located in central areas, whereas Ediya has concentrated on achieving cost leadership in all value activities as maintaining the quality of key products. Ediya succeeded in achieving best-provider strategy, in which it enjoys both cost leadership and differentiation advantages, largely by the strategic alliance with the biggest coffee manufacturer, Dongsuh Foods in Korea. Conclusions - Though Ediya is the imitator of Starbucks, it has modified Starbucks business models and succeeded in providing the 'third place' experience for budget-minded customers. Ediya has also succeeded in benefiting its franchisees by lowering costs and simplifying the various tasks of coffee shop management. Due to these factors, Ediya could become one of the largest number shops as the coffee franchise in Korea.

  • This study was undertaken to evaluate microbial risk degree of some processed foods in Korea. In this study the data on the outbreak of foodborne diseases during recent 18 years (1976-1989, 1993-1996. 8) were analyzed. The most frequently isolated pathogens were Salmonella (36.9%); followed vibrio (22.0%), Staphylococcus (15.7%) and Escherichia coli (13.3%). Outbreak rate of Staphylococcus, Vibrio, E. coli and Salmonella, was 33.0%, 23.5%, 17.5% and 17.1%, respectively. Overall risk degree of pathogens by fatality rate, outbreak rate and pathogen amount for foodborne outbreak was Clostridium, 5, Staphylococcus and Vibrio, 4, Salmonella and E. coli, 3. Based on foodborne pathogens, the risk degree of raw seafoods, raw eggs and processed seafoods were 4, and those of raw meats, Doshiraks and milk products were 3. Also, based on processing characteristics of foods, the risk degree of surimi-based imitation crab was 3. Foods of the highest actual risk degree were raw seafoods and raw eggs (16); followed raw meats (15), surimi-based imitation crab (12), Doshirak (9) and milk products (6).

  • This study explores on the static and dynamic growth patterns of high-tech ventures in Korea. We developed an integrative framework with target market (local vs. global), product/market maturity (existing vs. emerging), and technological capability (follower vs. pioneer). We also identified seven new ventures strategies as follows: i) reactive imitation, ii) proactive localization, iii) import substitution, iv) creative imitation, v) early market-entry, vi) global niche, and vii) global innovation. With five successful Korean new ventures, we found different competitive behaviors and performance among new venture strategic types. This study also observed two different growth patterns: growth through strategic replication and growth through strategic change. It depends on whether they are pursuing similar strategy over time or different strategy within for growth. In addition, we found that creative imitation plays a stepping-stone role in two-step internationalization processes. Although this study is exploratory and needs more empirical studies, it can provide new ventures with meaningful guidelines for growth and internationalization with a dynamic perspective.
