In this paper, we consider three-component reaction-diffusion system. With an integral condition and a global coupling, this system gives us an interesting free boundary problem. We shall examine the occurrence of a Hopf bifurcation and the stability of solutions as the global coupling constant varies. The main result is that a Hopf bifurcation occurs for global coupling and this motion is transferred to the stable motion for strong global coupling.

Although Korean apparel companies have transformed dramatically from contractors to sourcing companies thanks to the rapid growth of local market, relatively little work has been done identifying the determinants and the patterns of global sourcing activities of Korean companies. The purpose of this study was to outline a conceptual model that may be used to organize and guide global sourcing activities of Korean apparel manufacturers and retailers. The conceptual model identified four important factors, cost factor, strategic non-cost factor, firm's internal factor, and global factor, which affect global sourcing strategies and help predict how companies conduct various sourcing activities. The model also identified two sourcing patterns, outsourcing and intra-firm sourcing. In developing the model, literature review on how manufacturers and retailers in diverse areas including global apparel sourcing was conducted. Managerial implications and directions far future study were offered as well.

This research was carried out by setting hypotheses on recognition of the global image of the research subject, a domestic cosmetic brand and consequent quality of the brand, reputation of the brand, purchasing decision, influence of images of expanded countries and their correlations to investigate what effect the global images of local brands practically have on domestic consumers' purchasing decision. The analysis results show that overseas expansion of the research subject brand has positive influence on the brand possessing global images. However, it can be seen that the quality of the brand has much larger influence on the reputation of the brand than the images of global brand. In addition, the images of the expanded countries have influence on purchasing decisions but the global images based on the expanded countries did not have much influence on purchasing decisions. Therefore, it can be seen that global images based on high levels of brand reputation and quality are requirements of a most competitive brand than images of the expanded countries in forecasting likelihood of purchase.

Global climate change is significant issue in marine ecosystem and fishery market. According to rising of both seawater temperature and sea-level, global fishery environment and marine ecosystem are changing drastically. Moreover, over-exploitation in fishery areas is the most important issue in the marine ecosystem conservation. In analysis and statistics of global network, major fish populations are decreasing very fastly, but fish catch are increasing annually. It means balance between product and consume is not appropriate in the global market. China as emerging new fish consumer in the world is strongly developing fishery industry and technology. In this paper, I try to review a relationship between marine ecosystem and climate change in global scale according to references. I also suggested possibility of sustainable global fishery in changing marine ecosystem by analysis of some related reports of international global fishery.

This paper presents a new global intensity compensation method for extracting moving object in a visual surveillance system by compensating time variant intensity changes of background region. The method that compensates a little changes of intensity due to time variant illumination change and automatic gain control of camera is called global intensity compensation. The proposed method expresses global intensity change with a mapping table to describe complex form of intensity change while the previous method models this global intensity change with a simple function as a straight line. The proposed method builds the mapping table by calculating the cross histogram between two images and then by selecting an initial point for generating the mapping table by using Hough transform applied to the cross histogram image. Then starting from the initial point, the mapping table is generated according to the proposed algorithm based on the assumption that reflects the characteristic of global intensity change. Experimental results show that the proposed method makes the compensation error much smaller than the previous GIC method

Moment-based reliability analysis is the method to calculate reliability using Pearson System with first-four raw moments obtained from simulation model. But it is too expensive to calculate first four moments from complicate simulation model. To overcome this drawback the MD(multiplicative decomposition) method which approximates simulation model to kriging metamodel and calculates first four raw moments explicitly with multiplicative decomposition techniques. In general, kriging metamodel is an interpolation model that is decomposed of global model and local model. The global model, in general, can be used as the constant global model, the 1st order global model, or the 2nd order global model. In this paper, the influences of global models on the accuracy and robustness of raw moments are examined and compared. Finally, we suggest the best global model which can provide exact and robust raw moments using MD method.

This study generated a framework to help academicians understand consumers' cultural values and global-mindedness Especially, this study affirmed the importance of fashion involvement in evoking global-mindedness when consumers have strong traditional values. A conceptual model with non-traditional and traditional values as exogenous variables, global-mindedness as endogenous variable and fashion involvement as mediating variable were created for the study. Data from 224 female college students were analyzed for empirical study. Results indicated that college students showed higher level of non-traditional values than traditional values. Non-traditional values had significant direct influence on global-mindedness whereas traditional values did not have significant influence. Traditional values as well as non-traditional had significant influence on fashion involvement. Fashion involvement significantly affected global-mindedness. Both non-traditional values and traditional values had significant positive indirect effects on global-mindedness mediated by fashion involvement.

The objective of this paper is to review the mechanics of how global e-trade practices can affect a firm's performance. It is well known that the introduction of global e-trade systems can save transaction costs at the macro level. However this study is extended at micro level by determining whether global trade transaction costs influence positively or negatively in exporting firms performances at firm level. A theoretical framework is suggested for determining the usage and performance of global e-trade with the global e-trade barriers. An empirical analysis of South Korean exporting firms has been undertaken. This paper concludes that the global e-trade has yet to overcome the barriers resulting from the transaction costs and asset specificity. In this regard, appropriate action like intensive education and training program should be implemented in order to make South Korea's global e-trade more matured.

Infinite competition on ICT industries is starting again. The basis of competence over global dominance will be human resource, a global ecosystem for products and national agenda for science and technology, etc.. This paper presents the six solution for the Global Competitiveness and Coexistence of Korean ICT Industries. Korea should nurture the brand of "World Best Korean ICT Forever" to secure technical competency of ICT related fields in global market. All ICT technologies should be aligned to global standard and market demand from beginning and the ecosystem around product needs to be established. System framework for utilizing the resource of core SW experts must be established. Through global partnership with China as manufacturing base for Korea-developed products, technical competency can be maintained including product planning. Security measure for technical assets is mandatory. Finally, core technology that will drive the future of ICT industries in Korea should be regarded as core subjects.

SMEs are experiencing difficulties in doing sales promotion due to the low awareness of the image of the company and the products produced by them in the global market. Therefore, the Government should seek ways to raise awareness of SMEs' image and products. SMEs have to carry out global innovation activities needed to develop new products or new technologies, but they are exposed to limitations of these innovative activities due to the limit of their available resources. Therefore, as a national project, the Ministry of SMEs and Startups and the Small and Medium Business Corporation are doing project for fostering and constructing global shopping mall (independent mall) so that SMEs can strengthen their global innovation activities. The purpose of this paper is to contribute to succeeding in the project for fostering and constructing global shopping mall (independent mall) by studying the case of Zungle Incorporation which operates a global shopping mall and greatly increases exports by participating in this project, and identifying success factors of Zungle Incorporation in doing this project.
