Service R&D that adds high value to existing products and service by scientification, IT convergence, intellectualization is a core business of creative economy. It is necessary to examine the service R&D revitalization plan by establishing service R&D hub researching the service R&D because a shortage of facility and infrastructure makes impossible to turn ideas into products (service). This research aims at establishing the implementation plan of service R&D hub that invigorates local service industries and contributes to carry out the plan. Service R&D hub is a focal point of service R&D activities which inter-connects service R&D activities distributed across ministries of central government and fields of studies, and which invigorates service R&D activities and enhances competitive power of service industries in Korea. It is necessary to establish main hub like Service Engineering Research Center in Japan and Fraunhofer IAO in Germany which take the lead in national service R&D activities, and make it build the solid foundation of service R&D activities in public sector and also create service innovation ecosystem. Considering the interdisciplinary characters of service R&D, it is essential to establish additional sub-hubs to meet a variety of demands of service R&D. It is also necessary to establish 'Living Lab', an open innovation system, which connects research institutions, universities, and corporates to make them target the specific fields of their own, and enhance open R&D and innovation in service industries.

The purpose of this research is to measure the sensibility and preference of American consumers for domestically-manufactured cotton fabrics through 7-points scale questionnaires and the 4-dimensions and 8-axes system. The key words included such images as masculine-feminine, new-old, casual-classic, and ambiguous-orderly. The images of cotton fabrics were classified through a cluster analysis. This research also included an investigation of relationship between sensibilities for cotton fabrics and their physical characteristics. The sensibilities of cotton fabrics were classified into 4 groups: 'feminine sensibility,' 'masculine sensibility,' 'new sensibility,' and 'casual sensibility.' This result represents that American consumers' sensibility is simpler than Koreans'. The order of preference was 'feminine sensibility', 'masculine sensibility', 'new sensibility', and 'casual sensibility.' The sensibilities of cotton fabrics were explained significantly by stiffness, weight, weft density, value, and chroma. Specifically, those were more influenced by color characteristics such as value, chroma, and hue than by physical characteristics. We should be able to tell a difference in the reaction of a trading country's consumers and domestic consumers to domestically-manufactured cotton fabrics through comparing this research with the previous work(Shin & Lee, 2002). Additionally, we will be able to establish a basic strategy for successfully advancing Korean fabrics into the American domestic textile industry. In this way we can expect to increase the competitive power of our domestic clothes brands.

Among OECD countries, Korea is the only country which has continuously recorded total birthrate below 1.3 person for over 10 years. Since 2006, the Korean government has promoted the population policy in full scale. But, the fertility rate which became low has not shown any sign to go up again. Thus, Korea can be understood as having fallen into 'low fertility trap'. Such a low fertility can cause serious problems such as weakening of national competitive power and even survival of the country. In Korea, due to studies and finding jobs among young women, their childbirths are kept being postponed. In some cases, poor working conditions where women work can cause physical conditions not appropriate for pregnancy. Thus, it is very important to let childbearing women, pregnant women take care of their health. Accordingly, conscious of this low fertility era, this study examined major international organizations and countries' health promoting strategies-with focus on motherhood and suggested some methods to effectively improve health for motherhood.

As open skies polices have permeated all over the world, Korea's basic direction of aviation policy is promoting the benefit of the public and the national carriers' competitive power by establishing open skies agreements between the countries. The open skies' directions should be promoted by considering the relationships of various attributes such as governments, airlines, and passengers. To decide the right directions of open skies, we should investigate the economic effects of open skies policies. This research develops a simulation model to analyze the dynamic characteristics of open skies. By using the developed model, this research analyzes the economic effects of open skies. The results showed that open skies have direct impacts on not only frequencies, airfare, consumer welfare but also air transport industry and regional economy. Therefore, it is necessary to take suitable aviation policy that can increase the effects of open skies.

In knowledge-based information society, national competitive power is determined by human resources rather than by material resources. Therefore, training technicians with new skills has been gathering as a question Polytechnic colleges play an important role in training technicians as a 2 year courses educational institute conducting both master craftsmen and craftsmen and occupational training. At present, an electricity departments of polytechnic colleges should look at the reality of retraining which is taken more time and more budget for graduates' employment in the industries, as reorganizing in knowledge based school subject they also train the students to be the excellent poly technicians who have both theory and practice by reflecting new technology in developing curriculum needed at the jobsite to join in upgrading our country's competitiveness as a go-between technician at the jobsite. In this paper, a four-semester system was investigated to meet the condition of colleges educating the skilled technicians needed the industry by analyzing the status of polytechnic colleges.

$CO_2$ adsorption on mineral sorbents has a potential to sequester $CO_2$. This study used a density functional theory (DFT) study of $CO_2$ adsorption on barium oxide (BaO) in the presence of $H_2O$ to determine the role of $H_2O$ on the $CO_2$ adsorption properties on the ($2{\times}2$; $11.05\;{\AA}{\times}11.05\;{\AA}$) BaO (100) surface because BaO shows a high reactivity for $CO_2$ adsorption and the gas mixture of power plants generally contains $CO_2$ and $H_2O$. We investigated the adsorption properties (e.g., adsorption energies and geometries) of a single $CO_2$ molecule, a single $H_2O$ molecule on the surface to achieve molecular structures and molecular reaction mechanisms. In order to evaluate the coordinative effect of $H_2O$ molecules, this study also carried out the adsorption of a pair of $H_2O$ molecules, which was strongly bounded to neighboring (-1.91 eV) oxygen sites and distant sites (-1.86 eV), and two molecules ($CO_2$ and $H_2O$), which were also firmly bounded to neighboring sites (-2.32 eV) and distant sites (-2.23 eV). The quantum mechanical calculations show that $H_2O$ molecule does not influence on the chemisorption of $CO_2$ on the BaO surface, producing a stable carbonate due to the strong interaction between the $CO_2$ molecule and the BaO surface, resulting from the high charge transfer (-0.76 e).

The focus on the issues surrounding spent nuclear fuel and lifetime extension of old nuclear power plants continues to grow nowadays. A transparent decision-making process to identify the best suitable nuclear fuel cycle (NFC) is considered to be the key task in the current situation. Through this study, an attempt is made to develop an equilibrium model for the NFC to calculate the material flows based on 1 TWh of electricity production, and to perform integrated multicriteria decision-making method analyses via the analytic hierarchy process technique for order of preference by similarity to ideal solution, preference ranking organization method for enrichment evaluation, and multiattribute utility theory methods. This comparative study is aimed at screening and ranking the three selected NFC options against five aspects: sustainability, environmental friendliness, economics, proliferation resistance, and technical feasibility. The selected fuel cycle options include pressurized water reactor (PWR) once-through cycle, PWR mixed oxide cycle, or pyroprocessing sodium-cooled fast reactor cycle. A sensitivity analysis was performed to prove the robustness of the results and explore the influence of criteria on the obtained ranking. As a result of the comparative analysis, the pyroprocessing sodium-cooled fast reactor cycle is determined to be the most competitive option among the NFC scenarios.

In this paper, Nash equilibriums of generation markets are investigated using a game theory application for simplified competitive electricity markets. We analyze the characteristics of equilibrium states in N-company spot markets modeled by uniform pricing auctions and propose a new method for obtaining Nash equilibriums of the auction. We assume that spot markets are operated as uniform pricing auctions and that each generation company submits its bids into the auction in the form of a seal-bid. Depending on the bids of generation companies, market demands are allocated to each company accordingly. The uniform pricing auction in this analysis can be formulated as a non-cooperative and static game in which generation companies correspond to players of the game. The coefficient of the bidding function of company-n is the strategy of player-n (company-n) and the payoff of player-n is defined as its profit from the uniform price auction. The solution of this game can be obtained using the concept of the non-cooperative equilibrium originating from the Nash idea. Based on the so called residual demand curve, we can derive the best response function of each generation company in the uniform pricing auction with N companies, analytically. Finally, we present an efficient means to obtain all the possible equilibrium set pairs and to examine their feasibilities as Nash equilibriums. A simple numerical example with three generation companies is demonstrated to illustrate the basic idea of the proposed methodology. From this, we can see the applicability of the proposed method to the real-world problem, even though further future analysis is required.
