The main issue relating to electronic bill of lading is to develop the system in which can transfer the title to the goods by electronically, and to support effect of electronic transfer of title by law. BBL, electronic bill of lading being operated by bolero, provides technical devices to that purpose, but current law is not recognize the effect of transfer of title by electronic communication because BBL is different from paper bill of lading naturally. For that reason Bolero has resolved the problem by Rulebook which is multilateral agreement contracted between users and BAL. The Rulebook provides solution, so called, 'attornment' and 'novation'. So, The purpose of this study is to help in understanding BBL through comparison and analysis about the legal background of transfer of title by BBL based on 'attornment' and 'novation' with transfer of bill of lading based on a endorsement and delivery.

The most concerning issue in these days is the energy crisis by increasing threat of global warming and depletion of natural resources. In the situations, the Plug-in Hybrid Electric Vehicle (PHEV) is drawing attention from many countries for the next generation's car which has higher fuel efficiency and lower environmental impact. This paper presents simulation results about the limit capacity of central power-grid which doesn't have enough surplus electric power for charging PHEVs. Therefore, this paper also presents a smart charging system that can charge the PHEVs with a function of distributing demands of charging. The smart charging system is an agent facility between the government and consumer, which can recommend the best time to charge the battery of PHEVs by the lowest energy cost. This function of choosing time-slots is the technical system for the government which wants to control the consumption rate of electric power for PHEVs. Finally, this paper presents the economic feasibility of PHEVs from the two kinds of price system, midnight electric price and home electric price.

Nowaday, The Sustainable Development about global environment is the most important subject. In urban environment, a variety of the nature energy utilization such as the solar energy are the most efficient solution to solve this issue. One of these efficient solutions, a photovoltaic system using sunlight has been introduced to the building with an advantage such as cost-effective, safe for using and good for environment friendly in light with energy utilization. Recently, many of the apartment housings are built in domestic country. The apartment buildings have been constructed since early of 1970's. now apartment is taking over 50% out of entire housing in korea. The apartment housing applying to a photovoltaic system has been extensively studied in the foreign country but our county runs short. So, It was necessary to technical development of PV application which is suitable in Korean house culture. The objective of this study is to develop the building integrated PV application method for apartment building.

In recent year, animal welfare is more and more attracted public concern. Many countries have legislated animal welfare laws especially in EU. Now, it is appearing as an international issue in livestock product trade area because of animal welfare standard differences. The concept of animal welfare is not scientific but Ideological. In relation to consumer quality, animal welfare was defined confidential quality attribute. Therefore it is hard to approach to technical quality characteristic. This article reviewed interrelationships of animal welfare and product quality included in animal welfare as a quality factor, the mechanisms of determined quality influenced by animal welfare, relations of the type of animal welfare and quality profiles, and global perspectives.

The use of telematics, or of data communications, for the information services is a much debated issue currently in the information science. The purpose' of this study is to gain a general overview of the use of data communications in specialized information centers in order to find out the direction of development in furture. In this study, the state of the specialized information services by data communications in Korea was analysed from the following points of view: (1) What kind of role play the liberalization of telecommunication to help develope the specialized information services? (2) Which problems have happend to the specialized information services using data communications? (3) How are technical, economical, and methodical problems handled for the new services? The background research stems from interview with managers and researchers in 5 specialized information centers.

As power systems grow more complex and power demands increase, the fault current tends to gradually increase. In the near future, the fault current will exceed a circuit breaker rating for some substations, which is an especially important issue in the Seoul metropolitan area because of its highly meshed configuration. Currently, the Korean power system is regulated by changing the 154kV system configuration from a loop connection to a radial system, by splitting the bus where load balance can be achieved, and by upgrading the circuit breaker rating. A development project applying 154kV Superconducting Fault Current Limiter (SFCL) to 154kV transmission systems is proceeding with implementation slated for after 2010. In this paper, SFCL is applied to reduce the fault current in power systems according to two different application schemes and their technical impacts are evaluated. The results indicate that both application schemes can regulate the fault current under the rating of circuit breaker, however, applying SFCL to the bus-tie location is much more appropriate from an economic view point.

As technology level of TFT-LCD advances, application to TV becomes an emerging important area for LCD makers. In this paper, we review current LCD technology level to be used in TV such as liquid crystal response behavior, color accuracy, contrast ratio, brightness and panel size. Based on the understanding of current limitations in LCD compared with CRT, the improvement plan to render 'near perfect motion picture' reproduction with LCD is proposed. Digital TV is a great opportunity for digital LCD panels, but we have to solve remaining technical and cost issue in order to be competitive with other large size TV technologies such as PDP, CRT or projection type. In preparing the upcoming digital TV era with advanced TFT-LCD, the hurdles and prospect of larger size LCD-TV panels will be discussed.

Membrane type LNG Carriers are characterized by their special structures such as trunk deck above upper deck. It is necessary to introduce an appropriate structure arrangement taking into account transition of the trunk deck to the upper deck or deckhouse in fore and aft parts. The transition area at aft part -from trunk deck to the deckhouse - is to be specially considered because of high longitudinal stresses applied at the area. This study has been carried out to tackle the transitional structure problem in design stage This paper deals with not only mesh size of FE models for scantling evaluation and fatigue assessment but also technical issues regarding fatigue assessment.

The main components, such as a reactor vessel, in commercial nuclear power plants have been welded to pipes with dissimilar metal in which Primary Water Corrosion Cracking (PWSCC) has been occurred. PWSCC has become a worldwide issue recently. This paper addresses the results of experimental and numerical analysis to prevent PWSCC by changing the stress profile that is tensile stress to compressive stress at interesting regions with plastic deformation generated by mechanical pressure. Based on the results of experimental and numerical analysis with a 6 inch pipe and dissimilar metal welded pipes, compressive stress 68~206 Mpa is generated at all locations of inner surface in the heat affected zone.
