  • The pedestrian traffic flow has more complicated microscopic features than vehicular traffic flow. Without any designated lanes or any guidance, pedestrians naturally move and change their routes in two dimensional domain with ease. Thus the assessment of pedestrian comfort level should be considering the microscopic features of pedestrian flow. This study is aimed at developing pedestrian comfort criteria based upon pedestrian flow simulation model. This study suggests three criteria to determine pedestrian comfort level; the deviation of route, the acceleration of walk, and the number of collision. Each criterion, which can address the unique walking patterns of pedestrian flow, is represented as each different function with respect to traffic flow rate. The criteria can be the additional indicators to determine the level of service of pedestrian flow together with traffic flow rate and walking speed.

  • Journals are the main indicator to evaluate the level of the studies of a country. The main purpose of this study is to suggest the improvements of the current journal evaluation system to enhance the level of journal quality. To accomplish the above purpose, the 631 researchers are surveyed by internet for their recognition. The major findings are as follows. Firstly, the current registration process need to be maintained, however, need to reinforce the conditions to level up the journal level and to extend the term for keeping the rate. Secondly, the professionalism and credibility of the appraisers need to be reinforced to increase the equity and rationality of the current evaluation system. Thirdly, the evaluation process for the newly entering journal need to be more strict than the current system. Fourthly, the Korean citation index or Kor-Factor need to be applied to evaluate the domestic journals. Lastly, the restriction policy is need to constrain the number of journals.

  • In the time of the Fourth Industrial Revolution, we endlessly cross between the virtual and the real in our daily routine. Information saving method has changed from physical to virtual and the contents of a digital device can be a method of showing one's identity. A digital device can be seen as a virtual version of a 'wuderkammer'. With this perspective, this study focuses on the changes that has occurred in our daily interaction, the process of thinking, perceiving, and understanding in the time of 'digital wunderkammer'. In order to discuss this matter, this study looks at the two art work series - 'Universal Addressability of Dumb Things' and 'UniAddDumThs' - by a British artist, Mark Leckey and analyzes the digital environment of today, its visual expression, and the characteristic of 'digital wunderkammer' reflected in his art works. Through this study, we hope that the readers can understand the paradigm shift of today and expand the creative possibilities in this new era of digital revolution.

  • Recently, an important physical device of transportation, such as car, railroad, ship and aircraft has changed into electronic control unit. According to accident reports, the most of car accidents are caused by faults of embedded software loaded to computer control unit. The facts implies that the test to find defects in embedded software haven't performed sufficiently. As a result, it is necessary to establish the test procedures of embedded software based on safety assessment criteria. The objective of this proposal is to provide a unit test procedure complied with the safety assessment criteria for the embedded software. In addition, an effective unit testing procedure and defect analysis methods are proposed and a testing procedure using a safety criteria built-in tool is presented.

  • Electronic Commerce has already existed for over 20 years. The Bolero project initially had the support of TEDIS, and now is jointly financed by SWIFT(Society for World International Financial Telecommunications) which handles most of the electronic funds transfer for banks, and the Through Transport Mutual Assurance Association(the TT Club), a mutual insurance association most of whose members are drawn from the Multimodal transport industry or transport intermediaries. Bolero's mission is to provide guaranteed and secure delivery, in electronic form, of trade documentation, globally, based on a binding legal environment and common procedures, Bolero will also provide a platform for provision of neutral cross-industry services. TradeCard is a payment and settlement system that is an alternative to letters of credit. That is, TradeCard is a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet. Paperless, payment-guaranteed international trade transactions - which eliminate the traditional letters of credit with electronic certifications - are widely considered the most difficult B2B transactions to conduct.

  • Beyond the simple stage of technical development, the growth of information networks have changed areas such as the economy, communities, and education. Existing knowledge and new knowledge about these things have developed and either coexist or conflict with each other. It is difficult to predict the result of this interaction since old and new information is changing so quickly. The transition from a simple communication to an interactive communication is related to a changed communication environment which involves a more complex level of understanding. Establishing the new design concept which is aimed at the future and developing new educational programs which respond to these new information networks are important in order to educate designers who can adjust to the new information network era and construct design education. This paper reports research about the process of developing new education systems that explore the new design paradigms, the changing information network, and the proper approaches to developing design education programs which fulfill these requirements.

  • This paper constructed the single country sequential dynamic CGE model to analyze the economic impacts of subsidizing water industry under the GHG emission abatement policy in Korea. We introduced the carbon tax to reduce the GHG emission and made two scenarios. One is to transfer the total tax revenue to household. The other is to mix the tax transfer and water industry support. Our Simulation results show that the macroeconomic effects might be positive by subsidizing water industry compared with the pure tax transfer. However, the support of water industry doesn't contribute to head for the non-energy intensive economy because it's economic activity highly depend on fossil energy and energy intensive products as intermediate demand. This means that it is important to make efforts on the cost effective measures such as energy technology progress, alternative energy development, and energy efficiency improvement in water industry against climate change policy.

  • 8 Exclusive Median Bus Lanes(EMBL) are operated in Seoul metropolitan city after the opening of Chon-ho section in 1996. But the changes in the road traffic demand on the direct and indirect influence area have not reported. In this paper, before and after survey and analysis of road traffic demand on 3 EMBLs opened in 2004 are conducted. In summary, the traffic demand of 3 EMBL road section decreased dramatically to 24.7% after the opening and then increased 1.4% after a year. The traffic demand of detour road decreased to 2.9% after the opening and then increased 0.3% after a year. Considering measurement error as ${\pm}5%$, Road traffic demands on the influence area of EMBL section are a stable state after one year. So it is presumed that the trip demand on EMBL section using vehicle does not make a detour around the influence area but divert into another transport modal.
