The Bass model is the most widely used model in research of new product diffusion because it presents a nice explanation on the diffusion process of new products. However, it has a limitation that its performance of fitness is lower as the available data become less and also, the diffusion curve is bell-shape and so, it can not represent the various diffusion patterns. Recently, a two-pieces Bass model is developed and applied to analyze diffusion of 10 products. The results are encouraging in terms of fitness. However, diffusion pattern is not dealt with in the paper. In this paper, analysis of diffusion pattern is in depth addressed in two-pieces Bass model. It is shown that the diffusion curves are divided into 3 types with respect to the peak adoption rate and each type is divided into 2 types further. Takeoff time of a diffusion process is analyzed by using the inflection point and regime-change time where it represents the point that imitation and innovation parameters change. Empirical studies for 68 products(28 domestic products and 40 USA products) are performed to analyze the diffusion pattern. Findings are that diffusion patterns of all products except 1 USA product show type I and regime-change time becomes shorter as the introduction time of the product is later in domestic products and regime-change time can be regarded as a takeoff time in 47% of total 68 products.

The purpose of this article is to suggest what is the desirable direction of economic relationship between Korea and China. The economic relationship between countries is based on how the present network is. As the economic relationship between countries grows, the network between countries will expand. In the past, the economic relationship between Korea and China is cooperative one from the viewpoint of international division of labor. Korean industries was focused on the value-added and mid-advanced technology products, while Chinese was focused on the labor-intensive products. As the China's economy grows for more than thirty years, there is a great change in China's economic policies and environment. China's industry structure is moving from the labor-intensive industry to technology-oriented industry. China's exports to the global market is increasing very fast, and China's domestic market is also growing. The change in Chinese industries' structure bring about severe competition in the global market. The expanding China's domestic market is also good opportunity as the new market in the world. The change in China's industrial structure needs for Korea to establish the 'New Network" between two countries. Korea has to grab the new opportunities in the China's domestic market and find new cooperative network with the products and industries.

This study investigated the consumer acceptance process of the fourth industrial revolution new product to be introduced into the market in the future. The 4th Industrial Revolution new products are technological advances compared to the existing ones. The technology acceptance model that was used in the past has been modified to reflect variables like the social effects of the 4th Industrial Revolution, expected experience, and perceived risk. Modified models were proposed and verified. Six representative new products of the 4th Industrial Revolution were selected and examined by 40 respondents, and the hypotheses were verified using programs such as SPSS and AMOS. And conclusions and implications are as follows. First, the innovativeness of the fourth industrial revolution new products influences positive evaluation factors such as expected experience and perceived usefulness and it also affect positively to the perceived risk. In addition, the expected experience of the fourth industrial revolution new products has a great effect on the perceived usefulness and social influence, but it didn't affect to the perceived risk. Like the results of the TAM model, purchase intention of the fourth industrial revolution new products are strongly influenced by perceived usefulness. Finally, the perceived risk of the new product of the 4th Industrial Revolution had no statistically significant effect on the purchase intention, and the social influence of the 4th Industrial Revolution had a significant effect on the purchase intention. In general, respondents are highly aware of the social impact of the Fourth Industrial Revolution and seem to be very positive in this respect.

A continuous development of new products is the lifeblood for firms that hope to maintain competency in competitive environments. Ongoing success in these environments is dependent on whether the management can choose or can't chose the proper mix of new product development strategy, new product development process, and organizational structure. Rather than considering the interrelationship among these success factors, however, most previous studies of new products development have examined these issues individually. Moreover, because past research has been unidimensional in nature, there is a lack of knowledge about how new product development strategy, process, and structure could be linked up each other. Consequently, we have no complete perspective of the linkage among new product development strategy, process, structure, and performance. The purpose of this study is to examine the new product development strategy, process, and structure of firms, and explore the effect of each on performance as well as linkage among strategy, process, strategy and structure.

This study aims to develop the 21st century eco design-based fashion products by examining Taller Flora products and presenting eco design approaches. Eco design terms were examined based on literature, and Taller Flora products were explored based on literature and websites. The following research issues were discussed. First, eco design terms are totally handled, thus defining the eco design. Second, eco design-oriented Taller Flora products are examined to explore design approaches. Eco design aims to conserve and heal the global environment with focus on a greater understanding of and interest in nature. As such, eco design is based on a new modern concept of aestheticism that seeks to minimize environmental damage caused by the three processes of production and distribution use and disposal, to take social and moral responsibilities for such activities, and to avoid hurting the environment. Taller Flora brands seek to produce products by keeping close ties with indigenous communities in various nations, and by emphasizing and embracing indigenous people's craftsmanship spirit and creativity Indigenous people use eco-friendly materials and produce products with craftsmanship spirit, and their cooperation by linking different cooperative networks is a good model for strengthening fair trade networks. These addresses the problem of expanding design work through traditional crafting. Therefore, the features of Taller Flora brands presented a new method to approach the eco fashion. The research findings are expected to help develop the eco design of fashion products.

Objectives : To direct methods of management and development of herbs and their derived products, and at the end of this study to inform the process of making new herbal drug regulations in Korea. Methods : This study analyzed the regulations and laws of western medicine drugs. Results : We have got some herbal prescriptions which are not in the eleven books of oriental medicine now in use but which have proved effective. We need to establish standards for permissions to produce medical products through those prescriptions. Besides, we need the special permissions to produce herbal products through prescriptions, especially those which have been used to treat incurable diseases. And, we can contribute to globalization of oriental medicine and to well situating of herb products and medicinal acupunctures if we produce them according to international standards. It is thought that herbal medicine has no side effect in the medical society in Korea. But, it is getting popular to administer herbal medicine and western medicine together. Thus, the side effects of taking both medicines at the same time should be documented. Conclusions : Herbal medicines and herbal products should be under the control over the whole process of production, circulation, and sales. Now, it is time for herbal medicine to be known to all over the world. Therefore, herbal medicine must meet and adhere to the standards set by the western society and WHO.

This study examined the impacts of tariff reductions on timber products in the new round of WTO negotiations on domestic timber products markets and presented the measures to minimize their impacts. Scenarios on reductions in tariffs were developed based on result of UR negotiation and prospective issues on scope of tariffs bound, base rates for negotiation, degree of tariff cuts, etc. emerged during preparatory meetings held to launch the New Round of WTO Negotiation. Korea Timber Market Model(KORTIMM) developed by Korea Forest Research Institute was used to simulate the impacts on forest products markets by scenario. It was estimated that their impacts on net imports would be much larger than those on both consumption and production. The results showed that their impacts on plywood market and on net imports of processed forest products would be much larger relatively but that their impacts on log market and on consumption and production of processed forest products would be less than 1 percent. It was estimated that log consumption would be reduced due to reduction in domestic production of processed products and thus both production and imports of logs would be reduced as well. In oder to minimize the impacts, efforts should be made to start negotiations to reduce tariffs with bound rates for bounded products and with applied rates for non-bounded products, to expand the implementation period and to maintain the status of developing country. In addition, it might be one of countermeasures to use legitimate measures consistent with WTO rules such as anti-dumping, countervailing measures and safeguards.
