Opening 21th Century, all the Countries of the world has been focusing on build up the foundation of cultural infrastructure in a various way, since the awareness of importance for cultural design products has been turnover. On the other hand, our cultural crafts＇ industry has not escaped from poor working environment and lagging behind conventional product system, and yet there is no complete system for mass production. The study is collaboration with Tourism Industry Innovation Center in Kwangju University for development of cultural products of wooden crafts by using cultural resources in Kwangju area and CNC M/C which is up-to-date digital technology. It aims to make possibility of mass production and discrimination on design for wooden crafts which is based on highly skilled technical manpower and creativities, and expects to develop and merchandise global wooden cultural products.

Asphaltenes are generally defined by their solubility when a light alkane, such as n-heptane or n-pentane, is mixed with crude oils or oil sand bitumen. However, this definition is nowadays not enough to understand their behaviors during oil recovery, transport, storage, and even refinery operation. Interestingly, the researches regarding asphaltenes have been vastly presented within last decade. This is because the production of heavy oils is becoming larger and asphaltenes are known to play an important role in the property changes of heavy oils. In this paper, the researches regarding molecular weight, aggregation behavior of asphaltenes are introduced and discussed. It is expected that analytical studies will be appeared continuously in the form of global collaboration in order to describe asphaltene molecules as close as possible based on their origin.

The world wide web (WWW) already accounts f3r more Internee network traffic than any other application, including il and simple file transfer. It is also a collaborative technology in a weak sense of the word - it allows people to share information. Synchronous collaboration is where an interactive activity is simultaneous and in teal-time. Computer based real time collaborative systems like shared whiteboards. collaborative editor etc. are only beginning to emerge recently. These applications invoking more than two users exchanging information, require Multicast communication. Multicast communication is a transmission mode that is now supported by a variety of local and wide area networks. Multicasting enables multiparty communication across a wide area to sparsely distributed groups by minimizing the network load. Multicasting itself is one of the key technologies in the nut generation of the Internet This paper describes the technical issues from the aspect of multicast communication and its reliability in synchronous collaborative application.

Two major obstacles in the utilization of electrical vehicles are their price and range. The collaboration of direct torque control (DTC) with induction motor (IM) is preferred for its low cost, easy implementation, and parameter independency. However, in terms of edges, the method has drawbacks, such as variable switching frequency and undesired current harmonic distortion. These drawbacks result in acoustic noise, reduced efficiency, and electromagnetic interference. A feed-forward approach for stator-flux-oriented DTC with space vector pulse-width modulation is presented in in this paper. The outcome of the proposed method is low current harmonic distortion with fixed switching frequency while preserving the torque performance and simple application feature of basic DTC. The method is applicable to existing and forthcoming IM drive systems via software adaptation. The validity of the proposed method is confirmed by simulation and experimental results.

The Korean National Photovoltaic Project was initiated in October 1989 to develop technologies for the generation of economically competitive electric power by photovoltaic systems. It consists of four stages through the year 2006 with technical goals and cost targets related with solar cells, balance of systems and system application. The objectives of the project are to utilize photovoltaic technology, to transfer developed technology to industries and end users by research activities and to diffuse photovoltaic systems by demonstration projects. This paper reviews long-term plan abd status of technology R&D, and markets of photovoltaics. Some activities designed to promote collaboration with foreign countries are also introduced.

This study attempts to make an observation on the problems and prospects for overseas agricultural investment(OAI) through the insights of farming and farmed companies abroad and through secondary data. OAI mainly aims at the securing steady supplies of crops, which could be anticipated to have increased foreign dependence, and to prepare for crop price fluctuations in the international markets. These functions of OAT are classified with the public and private sector. The public sector needs are largely crops supply for national food consumption and bilateral collaboration between nations. The private sector needs are to gain maximum profits from agricultural investments and to produce raw material for self-consumption in overseas farming companies. The problems in OAI are legal and institutional restrictions in the project area or nation; generally economical unfeasibility in the farm projects, and technical limitations of the farming companies. The prospects of OAI are not very promising. The reason why those many companies which previously planned on OAI changed their investment plans after what is called IMF system with financing difficulties.

Nowadays, one of the major technical issues in manufacturing is how to implement an virtual plant as an well-designed, integrated environment for sharing information and engineering collaboration among diverse engineering activities. The systematic approaches to make a virtual plant based on a 3-dimensional CAD, cell and line simulation, database and internet technologies are proposed in this paper. To do that, measuring and 3D CAD modeling technologies of many equipments, facilities and structures of the building are developed, effective management of information including models and related files in WWW environment is implemented, and precise simulations of unit cell and whole structured plant are performed. For the beginning of implementing a Virtual Automotive Plant, the Virtual Plant for the Body Shop of a Korean automotive company is constructed and implemented, Using this Virtual Plant ...

Unlike the popular belief, digital transformation mainly gets stymied by legal and regulatory issues related with legacy institutions in Asia rather than technical difficulties. The real challenges triggered by the PSD2 (Payment Services Directive 2) are how the region would overcome the overly fragmented, centralized, and hierarchical legacy framework to allow necessary changes to respond to the digital single market initiatives as promulgated by the European counterpart. The PSD2 is expected to bring about substantial changes in the payment ecosystem by allowing payment service providers to access customers' accounts and transactions information via API that have been traditionally controlled by banks. This paper suggests an incentive-compatible mechanism design for open collaboration among legacy institutions in the region to help them adapt to the PSD2. As evidenced by case studies in Korea, the Asian equivalent of PSD2 can be implemented and further expanded to create region-wide PCS (payment-clearing-settlement) network by reconnecting the dots of legacy infrastructures. These decentralized, diverse, small payment networks can be further combined with the expanded RTGS-CDS platform to evolve into the next phase of Asian Financial Network.
