Globalization of economy has a significant impact on the organization of economic Space. This paper examines the concepts of globalization and localization, major trends of the changes in the organization of economic space in the Pacific rim, and the major processes of the changes. Intra-regional trade and foreign direct investments have increased considerably in the Pacific region with the progress of globalization during the last decade. Due to the Progress of globalization of economy in the Pacific rim, some growth triangles have extended their agglomeration area beyond the national boundaries and several new industrial districts have developed. The reorganization of the economic space in the Pacific rim has been resulted from industrial restructuring of NIEs, spatial division of labor along the commodity chains, and the formation of industrial networks within the region. The ‘cooperative network strategy’has been suggested to minimize the negative effects of glocalization and for the sustainable development in the Pacific rim.

This study investigates the time-space characteristics of the consumptions of cultural-contents commodities and their spatial diffusion progresses via digital media. For the purpose, we examine the spatial diffusion patterns of PSY's Music Video "Gangnam Style" since it has been launched on the YouTube. By visualizing the spacio-temporal progresses of YouTube, Tweet, and Google searching data during four months after launching, we examine the time-space characteristics of diffusion patterns of the music video via each media. We found that the adapting time and the diffusion progress were not in accordance at each country. The results revel that cultural distance such as characterized by language, cultural linkage, exclusivism or courtesy for the 'Hanrue' affects quite strongly on the spatial diffusion of music video rather than physical distance.

Various kinds of tile-based ultra-high resolution display devices have been developed by, for example, constructing display walls using many commodity LCD displays. To represent 3D applications like computer games on these devices, one has to develop 3D applications or develop particular APIs only for representing on these devices. If one can develop a distributed rendering system using legacy 3D APIs such as OpenGL and Direct3D by extending a remote rendering system, commercial computer games can be represented on such display devices without modifying their source codes. The purpose of the paper is to propose a new Dired3D-based distribute rendering system by extending a Direct3D-based remote rendering system and to show its feasibility technically by appling it to a sample Direct3D application and performing a few experimentations.

Brick is not only aesthetically beautiful and emotional material, but also eco-friendly and good building commodity for human health. Nonetheless, the use of brick has declined, due to the difficulty of building high-rise buildings and the limitation of the free form implementation. However, modern society is increasingly interested in environmentally friendly finishing materials for solving environmental problems. From this point of view, the brick architecture is being reexamined as a material to improve the living environment and to provide comfort without destroying nature. In addition, the development of digital technology enables the implementation of various types of masonry method and curved forms. Parametric design is one of the ways to realize the curved forms and various architectural expressions for brick architecture. In this background, the purpose of this study is to develop algorithms that can easily generate curved brick walls through parametric design, enable various pattern designs, and respond to real-time feedback. The details of the study are as follows. First of all, we examine organic architecture, the trend of brick architecture, and the concept of parametric design. Secondly, In order to generate curved surface with complex curvature, major planning factors affecting form generation are examined. Finally, we develop a parametric design method that consists of generating a curved surface for brick arrangement, implementing a parametric algorithm, and generating a curved form using bricks. Consequentially, we propose an algorithm that can maximize the use of ready-made bricks without using cut bricks to design curved walls and present efficient and economical design alternatives.

The technologies relevant to e-business have rapidly developed during very short period of time and recently it is expanding to the area of B2B. Keeping pace with this development in e-business, the information of comparison or analysis on commodities of a lot of sites is also required. Though the information on price comparison among internal shopping malls are now being offered, its not efficient for its renewing intervals are long and, due to some indiscreet collection of information for the purpose of fast renewal, much loads are being generated on the pertinent shopping malls. In this article, the retrieval engine on demand is designed and realized using a dynamci robot agent changing kinetically on the status of the pertinent shopping malls that can offer the customized service and presents the shopping malls with the lowest price for each commodity under e-business after the shortest time of collection and analysis while not giving loads to the pertinent shopping malls.

Abalone is a primary commodity that is almost traded as live fishes. So the application of 'addition' is common in local transaction of abalone. Nevertheless, an excessive application of addition leads to some social problems. The abalone industry is one of the most rapidly growing industry in fisheries. This growth is caused by propagation of sea cage and mechanization of feeding. As a result, the abalone distributers are increased. However, the distributers have great bargaining power, so they sometimes claim excessive addition rates to aquacultural abalone producers. Difference in fitted level of the addition rates between distributers and producers cause some problems as an aversion to shipping of abalone. Also, the words about addition have not clear definition yet. So many related terminologies, for example, addition, deviation, and loss, those have different meaning are in used. And unfortunately many industry insiders use the words, 'addition', mixed with other related terminologies on transaction. The main objective of this study is to clearly define addition's meaning on the abalone transaction and to analyze the correlations between the addition and the abalone prices, outputs, and exports. Analysis results show addition negatively affects abalone prices and outputs. Furthermore, addition contributes to abalone exports negatively contrary to expectation. Such results can provide information that 'stabilization of supply and price of abalone' is realistically better method than 'increasing of additional rates' to expand abalone exports. Negative correlations between variables tell that a dictionary definition of addition, a free as seller's benevolence, is divorced from reality of abalone industry. Therefore "Loss", that means preservation in unintentional loss of abalone objects, is more suitable than "Addition" on abalone transaction.

Polyolefin is one of the most important commodity polymers having excellent physical properties and cost competitiveness, which has continuously broadened their market in response to a heavy demand from industry. However, the lack of polarity in polyolefin has limited its applications, especially where interactions with other materials are important. In view of the above, the incorporation of polar functional groups in polyolefin has been widely attempted. Especially, the preparations of segmented modified polyolefin copolymers, such as block and graft copolymers have been extensively investigated, since the loss of the original properties of polyolefin can be minimized while the polar segments can endow interactions with other materials. Living radical polymerization (LRP) method can be one of the most attractive synthetic tools for the preparation of the modified polyolefin block or graft copolymers. In this review, progress on the preparation of the polyolefin based block or graft copolymers through LRP technique is briefly summarized.

Peer-to-peer systems (P2P) are rapidly growing in importance on the Internet environment, quickly extending the range of their usage. However, peer-to-peer systems have not been widely applied in electronic commerce because they have not been established as an appropriate business model. Therefore, we firstly review the previous research relevant to peer-to-peer systems, and then analyze the business models for P2P systems presented by previous researchers. Furthermore, this study categorizes major issues in terms of the technical and business model aspects. On the basis of these reviews, we develop P2P electronic commerce systems based on the file sharing method between users, focusing on user interface friendliness. A developed P2P electronic commerce systems are programmed by using the C# based on the Microsoft.net solution. A database is implemented using the MSSQL2000. A main application technology is designed that P2P electronic commerce systems make it possible. for user to extend into BtoB Solution by using WSDL (Web Services Description Language), UDDI (Universal Description, Discovery, and Integration) and the XML that is a document for users. User interface is made as form of Internet messenger for a user's convenience and is possible to develop into a commodity transaction system based on XML. In this study, it is possible for the P2P electronic commerce system to have extended application to fields such as Internet shopping mall and property transaction in a nonprofit organization, a public institution and a large scale nonprofit institution that have a similar structure as compared with a structure of a nonprofit educational institution.

In recent year, energy harvesting technologies from the ambient environments such as light, motion, wireless waves, and temperature again a lot of attraction form research community [1-5] due to its efficient solution in order to substitute for conventional power delivery methods, especially in wearable together with on-body applications. The drawbacks of battery-powered characteristic used in commodity applications lead to self-powered, long-lifetime circuit design. Thermoelectric generator, a solid-state sensor, is useful compared to the harvesting devices in order to enable self-sustained low-power applications. TEG based on the Seebeck effect is utilized to transfer thermal energy which is available with a temperature gradient into useful electrical energy. Depending on the temperature difference between two sides, amount of output power will be proportionally delivered. In this work, we illustrated a low-input voltage energy harvesting circuit applied discontinuous conduction mode (DCM) method for getting an adequate amount of energy from thermoelectric generator (TEG) for a specific wearable application. With a small temperature gradient harvested from human skin, the input voltage from the transducer is as low as 60mV, the proposed circuit, fabricated in a $0.6{\mu}m$ CMOS process, is capable of generating a regulated output voltage of 4.2V with an output power reaching to $40{\mu}W$. The proposed circuit is useful for powering energy to battery-less systems, such as wearable application devices.
