The study was carried out to evaluate the storage and quality characteristics of Duteoptteok added with mugwort. The content of moisture and crude fiber in Duteoptteok significantly increased while that of the crude protein and crude ash decreased by adding 10, 20 and 30% of mugwort. As for the color value, the L, a, b value of Duteoptteok decreased as the amount of mugwort increased. Also, the L value decreased by the increase of the storage period. However, the a and b value didn't show any significant difference. For the texture characteristics, as the amount of mugwort increased, the hardness, springiness, cohesiveness, gumminess and chewiness decreased; however, the adhesiveness increased. Moreover, the hardness, adhesiveness, gumminess and chewiness increased according to the changes of the storage period, while the springiness and cohesiveness decreased. According to higher amount of mugwort, the gelatinization degree increased while the retrogradation degree decreased. The viable cell count and yeast and mold count showed a decreasing tendency as the amount of mugwort increased while they increased by increasing the storage period. The results from this study suggests that the quality characteristics of Duteoptteok improved and storage period became longer by adding mugwort.

In the information-oriented society of 21st century, the added value of creativity has never been so important to need any further discussion. This research investigates an implication of metonymic activities in early childhood Convergence arts education as a basis of the creative education by analyzing EduDrama, the program which helps children acquire creativity through metonymic activities. To this end, this research proposes a desirable way of early childhood arts education by organizing limited situation of early childhood education in Korea with domestic and foreign cases applying metonymic activities. Despite actively conducted studies on arts education led by existing arts management field in Korea, arts education research for early childhood is still not entirely satisfactory. Therefore, this research makes clear the value of arts education using metonymic activities provided during early childhood on the assumption that the added value of our life depends on the creative human resource of 21st century.

Recently, DDS (Distributed Database System) has been often implemented on VAN (Value Added Network) as we know the amazing expansion of information network. DDS can yield significant cost and response time advantages over centrailzed systems for geographically distributed organizations. However, inappropriate design can result in high cost and poor response time. In a DDS design, the main problem is 1) how to select proper computer, and 2) how to allocate data fragment into proper nodes. This paper addresses DDS design problem of selecting the proper class of computers and the allocating data files on VAN. Also, the formulated model includes tow objectives, the operating and investment cost. GA (Genetic Algorithm) is developed to solve this mathematical formulation. A numerical experiment shows that the proposed method arrives at a good solution.

The national boundary's meanings turn to weak according to advent of Global enterprises. The place for design a product and marketing are separated to actual market. R&D is to the area where the knowledge activity is well, and low skilful product assembling is to the place the low wage is acceptable. It shows that the importance of net work structure. From early 90's, production system is diversified to markets where with the consumer as the central as multifarious items and creation new demands through consumer's participation into manufacturing process. This phenomenon show that logistics structures adapt to demand of technical variation, and the development of e-business with VAN(:value added network) and EDI(:Electronic data interchange) prove it. This study tried to analyze utilitarian assay about systems those land, sea, air logistics through documents research, and this study also present the direction of logistics system of airline company and goal of development on the based to the model of domestic airline company accordingly.

Location-based services are a recent concept that integrates a mobile device's location with other information in order to provide added value to a user. Although Location-based Services provide users with comfortable information, it is a complex task to manage and share heterogeneous and numerous data in decentralized environments. In this paper, we propose the Semantic LBS Model as one of the solution to resolve the problem. The Semantic LBS Model is a LBS middleware model that includes an ontology-based data model for LBS POI information and its processing mechanism based on Semantic Web technologies. Our model enables POI information to be described and retrieved over various domain-specific ontologies based on our proposed POIDL ontology. This mechanism provide rich expressiveness, interoperability, flexibility in describing and using information about POls, and it can enhance POI retrieval services.

Recently, as change in global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information connection and utilization, code/data standardization. In this paper, the survey result of global logistics environment change, logistics policy of a developed countries, domestic logistics policy and information system status will be presented. And from these status, suggestive points are mentioned. Finally the status of railway logistics information and future developments are presented.

Location-based services or LBS refer to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless Internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless Internet, the LBS have reconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. However, there are fears that this new wealth of personal location information will lead to new security risks, to the invasion of the privacy of people and organizations. This paper describes a novel security approach on open LBS service to validate certificate based on current LBS platform environment using XKMS (XML Key Management Specification) and SAML (Security Assertion Markup Language), XACML (extensible Access Control Markup Language) in XML security mechanism.

This paper describes the characteristics and outline of rules of origin among Korea and USA, EU, ASEAN. The main focus of this paper is to conduct comparative analysis on rules of origin. Rules of origin are used to determine the country of origin of a product for purposes of international trade. There are two common types of rules of origin depending upon application, the preferential and non-preferential rules of origin Non-preferential rules of origin are used to determine the country of origin for certain purposes. The basis for the non-preferential rules originates from the Kyoto convention which states that if a product is wholly obtained or produced completely within one country the product shall be deemed having origin in that country. For a product which has been produced in more than one country, the product shall be determined to have origin in the country where the last substantial transformation took place. To determine exactly what was the last substantial transformation, three general rules are applied : Change of tariff classification(on any level, though 4-digit level is the most common), Value added-rule.(ad-valorem), and Specific process rule. While criteria of wholly obtained or produced in one country is almost similar to those of theses area and countries, in compliance with value percentages of Substantial Transformation, sufficient working or processing, Korea-US FTA adapts 'Regional Value Content', meanwhile Korea-EU FTA adapts 'Import Content' rule. Finally, Korea-US FTA and ASEAN FTA adapt FOB price for the calculation value added, on the other hand Korea-EU FTA adapts EXW price.

In this paper, we studied the path determination algorithm of the guidance robot for the visually impaired. Using the guidance robot for the visually impaired, the visually impaired can go to the destination where they want without other's heir. The navigation path of the guidance robot for the visually impaired must be the optimal path not only the shortest but also the most safe, which is different from a shortest path for common people. GPS and electronic map are used for the location information of the visually impaired. We corrected the error by converting the coordinates of location information from GPS, which includes maximum several tens of meters error, to the coordinates of electronic map. Information such as simple path and direction to the destination is not enough because it may be different between a going path from the start to the destination and a coming path from the destination to the start as around environment. So, we added information which can be dangerous for the visually impaired such as driveway, sidewalk without braille blocks, crosswalk, stairs and overpass, each has weight value as dangerous degree, when matching the GPS information to the electronic map, enough large as 1:5,000 scale.

In this paper we suggest a 32 bit high speed parallel multiplier which plays an important role in digital signal processing. We employ a bit-pair recoding Booth algoritham that gurantees n/2 partial product terms, which uniformly handles the signed-operand case. While partial product terms are generated, a special method is suggested to reduce time delay by employing 1's complement instead of 2's complement. Later when partial products are added, the additional 1 bit's are packed in a single partial product term and added to in the parallel counter. Then 16 partial product terms are reduced to two summands by using successive parallel counters. Final multiplication value is obtained by a BLC adder. When this multiplier is simulated under 0.8$\mu$CMOS standard cell we obtain 30ns multiplier speed.
