Purpose - In the major global markets, such as US and China, consumer ethnocentrism has been strengtened and there is a growing need for related study. This research aims to investigate the effects of national pride and national attachment on consumer ethnocentrism, using a nationally representative dataset from 2013 Korean General Social Survey. Based on the reviews of literature in social and political sciences, two dimensions of national pride were considered: national society pride which is based on positive evaluations on the nation's democracy condition or social security system, and national achievement pride which is based on positive evaluations regarding the country's achievements in the areas of technology, art, sports, and so on. Research design, data, and methodology - The authors developed a structural model in which two types of national pride, national society and achievement pride, are proposed to affect national attachment, thus influencing consumer ethnocentrism. 1,294 surveys were used for empirical analysis. The hypotheses were tested by utilizing SPSS 22.0 and AMOS 21.0. The unidimensionality of each construct and the nomological validity were supported from the results of factor analyses and correlation analysis. Results - It was found that both national society pride and national achievement pride have significant and positive effects on national attachment. Consumers who show stronger pride on the social systems or the global achievements of Korea are more likely to remain being a citizen of the country and support the country even in wrong. Also, there was a significant and positive relationship between national attachment and consumer ethnocentrism. Korean consumers who have stronger attachment to Korea tend to express higher ethnocentrism to protect Korean labor market and to promote economic development of the country. Conclusions - The findings of this study showed that companies and government need to emphasize the country's advanced social environments or global competitiveness in technology, sports, art, and so on, to boost national attachment. With a deeper understanding on the relationships among national pride, national attachment, and consumer ethnocentrism, the authors expect that both local and foreign companies in Korea will be able to develop more effective marketing strategies and to achieve sustainable competitive advantage.

The eighteen (18) F₁ hybrid combinations were tested to identify potential combinations adaptable to type 1 climatic conditions in the Philippines. The six (6) bivoltine purelines (DMMMSU 108, DMMMSU 109, DMMMSU 110, DMMMSU 111, DMMMSU 113, and DMMMSU 119); and three (3) multivoltine purelines (DMMMSU 1000, DMMMSU 1007, and DMMMSU 1014), were crossed (multivoltine x bivoltine) in a mating plan. These were arranged in a Completely Randomized Design (CRD), replicated three times, and analyzed using Analysis of Variance (ANOVA). A test of significance was done using ANOVA across years and Tukey's Honest Significant Difference Test (HSD). The multiple trait evaluation index (EI) method was also used in the identification of potential F₁ hybrids. Three major phases were done: (1) parental rearing of multivoltine and bivoltine pure lines for breed multiplication; (2) hybridization process; and (3) evaluation of F₁ hybrids. Rearing evaluations were conducted for three consecutive years. Based from the three evaluations, 10 potential crosses were identified: DMMMSU MV-12, DMMMSU MV-11, DMMMSU MV-13, DMMMSU MV-16, DMMMSU MV-07, DMMMSU MV-14, DMMMSU MV-05, DMMMSU MV-09, DMMMSU MV-03, and DMMSU MV-10. The topmost combinations with the best economic and commercial characters and are consistently adaptable during two (2) cropping seasons were DMMMSU MV-07, DMMMSU MV-12, DMMMSU MV-05, DMMMSU MV-09 and DMMMSU MV-11. These newly-identified F₁ hybrids are considered potential breeds that could improve cocoon production.

Many companies launched convergence products that are merged with several functions. Mobile convergence has some advantages such as portable convenience, usability of use, economic advantage that takes parts of the common component among products in the aspects of the digital products. Even though a plenty of items launched by convergence boom in the market, not tons of convergence products succeeded in the market because One of the major reasons is that companies don't take consumer evaluations in the process of the product development. It is important to set up infrastructure and excellent quality of the products for lasting the lifecycle of the convergence items. But, above all, it is imperative to find out how consumers evaluate convergence products and what they are affected to meet their satisfaction. Nevertheless, there are few case studies about consumer evaluations in mobile convergence until now. This study is to find out how consumers evaluate convergence products and what is the factor. This study surveyed 158 subjects and used multi-regression analysis and ANOVA(analysis of variance). The results of this study show that factors such as relative advantages, complexity, observability, perceived convenience affect the attitude of consumers.

Economic evaluation of the manufacturing technology of high-value chemicals through the carbonation reaction of carbon dioxide contained in the flue gas was performed, and analysis of the IRR (Internal Rate of Return) and whole profit along the production plan of the final product was conducted. Through a carbonation reaction with sodium hydroxide that is generated from electrolysis and by using carbon dioxide in the combustion gas that is generated in the power plant, it is possible to get a high value products such as sodium bicarbonate compound and also to reduce the carbon dioxide emission simultaneously. The IRR (Internal Rate of Return) and NPV (Net Present Value) methods were used for the economic evaluation of the process which could handle carbon dioxide of 100 tons per day in the period of the 20 years of plant operation. The results of economic evaluation showed that the IRR of baseline case of technology was 67.2% and the profit that obtained during the whole operation period (20 years) was 346,922 million won based on NPV value. When considering ETS due to the emissions trading enforcement that will be activated in 2015, the NPV was improved to a 6,000 million won. Based on this results, it could be concluded that this $CO_2$ carbonation technology is an cost-effective technology option for the reduction of greenhouse gas.

It is not so long that the cultural industrial sector has been noted as one of the major engines of regional economy in Korea. In parallel with balanced development strategies recently emphasized in the Korean regional policy, there has been a wide range of investment to formulate cultural industrial districts in major cities. This trend of investment focus has changed the development strategies of each city. There are criticisms, however, to this public sector-dominated nurturing of cultural economy. This paper overviews the recent policy of cultural industrial districts in Korea, in terms of its background, institutional basis, performances, and some evaluations. Some suggestions are provided in order to make the policy successful; emphasize developing the culture industry itself, develop clusters specifically focused on the characteristics of the culture industry, deliberate substantial measures for nurturing companies and human resources in the local regions, and formulate a system in which the local dominates and the center supports.

For improved sustainability of the biorefinery industry, biorefinery-byproduct glycerol is being investigated as an alternate source for hydrogen production. This research designs and optimizes a hydrogen-production process for small hydrogen stations using steam reforming of purified glycerol as the main reaction, replacing existing processes relying on steam methane reforming. Modeling, simulation and optimization using a commercial process simulator are performed for the proposed hydrogen production process from glycerol. The mixture of glycerol and steam are used for making syngas in the reforming process. Then hydrogen are produced from carbon monoxide and steam through the water-gas shift reaction. Finally, hydrogen is separated from carbon dioxide using PSA. This study shows higher yield than former U.S. DOE and Linde studies. Economic evaluations are performed for optimal planning of constructing domestic hydrogen energy infrastructure based on the proposed glycerol-based hydrogen station.

The advanced industrial economies have been suffering from rapid de-industrialization since the 1970s. In order to overcome such crisis, many countries have attempted to establish science parks and technopoles. Sophia Antipolis in France is one of the best examples of the worldly known technopoles, which was launched in the late 1960s. However, earlier evaluations on the technopole were not positive, while there were no dynamic innovative activities among institutions and firms of the technopole at least up to the early 1990s. While some changes in such circumstance have been observed since then, this paper attempts to investigate the changes and transformations occurring from the technopole since the late 1990s. Based on the review of the recent publications, statistics and expert interviews, the current paper concludes that Sophia Antipolis has been transformed into a dynamic and innovative technopole.

Recently, more and more firms are considering the adoption of RFID technology because it is expected to make process automation easier and has many different application areas. A review of existing studies about RFID adoption methodology shows that the most of the proposed methodologies are mainly based on economic evaluations. However, in the near future when the adoption and diffusion of RFID become major forces among business firms, it would surely have some limits to decide its adoption solely on the basis of economic considerations. In order for all the important strategic objectives to be considered during the major decision processes, it is necessary to make explicit what the decision makers really want to achieve from the RFID system. In this paper, we propose a general value model of RFID system which can provide an overall vision of all values RFID adoption may offer and a way to search and evaluate alternatives on the basis of these values. Especially, this model contains not only opportunities but also risks of RFID adoption so that a balanced consideration can be made. The model building process was essentially based on the 'value-focused thinking' approach proposed by R. Keeney. The proposed model is expected to provide insights about what to do in the process of introduction in order to maximize the potential benefits and minimize the negative risks. Referring to this value model, the important decisions would have greater chance to be based on a balanced consideration of opportunities and risks.

Research and development works on practical application of natural energy utilization systems involving solar, wind and sea wave energies are under promoting for the purpose of improving the energy consumption structure. These natural energies, made available with the use of relatively simple apparatus, are clean economically efficient and highly effective in the conservation of environment. However, these natural energies also have low energy density, randomness and regional variations. To compensate for these characteristics, hybrid utilization of solar and wind energies is currently under study. The introduction of a plural number of the natural energy hybrid utilization systems into a specific area will affect the economic efficiency, reliability and environmental conservation. Evaluation method of such effects has been examined in this study. The present method consisted of the steps described below. First, available energy was calculated from insolation distribution and wind velocity distribution in the specified area, and then the effect on the configuration of the power system load was obtained. This was followed by the determination of the optimal power dispatch over the specified period and by evaluations in light of economic efficiency, reliability and environmental indices.

Local governments within the boundaries of a state need increasing flexibility to satisfy diverse economic, social, and environmental goals in their particular geographical setting. However, many candidates in the local election in South Korea tend to see local politics as an extension of national-level politics. In particular, this paper mainly deals with how the voters' evaluation of a president's performance has influenced subnational elections in South Korea. Our analysis suggests that the fate of candidates in subnational elections is shaped by the performance of the incumbent president in both economic development and foreign affairs.
