The purpose of this study is to suggest concrete approaches of copyright application among various map price policies to establish the system of a digital map market, to revitalize its market, and to give the public better map services. To do this, we analyzed copyright law in Korea and the copyright protection of digital map in foreign countries firstly, investigated the applicability of copyright to the map market in Korea, analyzed the effect on this market, and suggested an direction of the revision for the Surveying law and the National Geographic Information (NGlS) law lastly. We drew several conclusions. Firstly, the protection of the rights of database makers is the best approach to protect digital maps in korea. Secondly, we need to adopt copyright to the Surveying law and the National Geographic Information Systems (NGlS) law. Lastly, establishing a copyright trust organization to improve the quality of digital maps and to manage various affairs is needed.

In this study the characteristics of E-EGR valve developed by Unick were analyzed and the feasibility of application to vehicles were evaluated. Smart car (3$\ell$/100 km) and engine which is small-displacement size, 0.8-liter, of diesel passenger car developed from Mercedes-Benz were used for this experiment. It was installed a 3-cylinder turbo-charged light duty diesel engine with an electronic EGR valve. After the analysis and comparison of E-EGR valve performance under test benches, the estimation of vehicle application was executed through the EGR map and CVS-75 test result measured on the chassis dynamometer.

The LBS (Location Based Service) location information is the element which is important decides the application of form service, Recently the location accuracy with the method which applies the wireless Internet DGPS improved inside 1 meter Like this. application of the LBS which corresponds In the location accuracy which Improves accurate the Location Information output system development which is accurate stands is essential. In this study which it sees it used 1:5000 digital map MS visual 6.0 Active X controls of the country geography intelligence Personnel and it developed the location information output module of web browser base. The location information output system which is developed it will be able to secure the convenient characteristic of precision and visual program of the digital map simultaneously and the maximum anger of LBS application is expected.

In this thesis, we present process that remove mistake of data before statistical analysis. If field data which is not simple examination about validity of data, we cannot believe analyzed statistics information. As statistical analysis information is produced based on data to be input in statistical analysis process, the data to be input should be free of error. In this paper, we study the application of statistical analysis road map that can enhance application on site by organizing basic theory and approaching on initial data exploratory phase, essential step before conducting statistical analysis. Therefore, access to statistical analysis can be enhanced and reliability on result of analysis can be secured by conducting correct statistical analysis.

Noise maps are produced according to 'The Method of making a Noise Map' in order to noise control efficiently, and prediction model to predict road traffic noise which may apply to Korean situation, include CRTN, RLS 90, NMPB, Nord 2000 and ASJ 2003. Of them, ASJ 2003, Japan's prediction model has not been verified for the application to Korean situation according to the classification of vehicle. In addition, ASJ 2003 was revised to ASJ 2008 recently, a classification for motorcycle was added. This study attempts to check the classification of vehicle in ASJ 2008 and 'The Method of making a Noise Map' to confirm the suitability of the application of them to Korean situation.

In 1799, Korea has become a country that holds Earth observation satellite in orbit as they had succeeded in the launch of KOPMSAT-1, the first Korean Earth observation satellite for the practical purpose. For the wide application of the satellite imagery, various application techniques are required, and topographic mapping is essential technique for the application in various fields. Moreover, considering that the main mission of the KOMPSAT-1 is to provide the satellite imagery for the mapping of Korean peninsula, the topographic mapping using KOMPSAT-1 EOC imagery is very significant. In this paper, we showed the possibility of digital plotting using KOMPSAT-1 EOC stereo images to produce topographic map. For the purpose, we implemented experimental stereo plotting using digital photogrammetric workstation and analyzed the procedure. As a result of this paper, we showed that some elements consist in 1:25,000 scale map can be plotted from KOMPSAT-1 Stereo images.

본 논문에서는 타블렛을 이용해 사용자로부터 주름 스케치를 입력받아 피부 패턴을 고려한 사실적인 얼굴 주름을 생성 할 수 있는 인터페이스를 제안한다. 주름을 생성하고 싶은 모델의 normal map에 간단한 스케치를 하면 해당 모델의 피부 패턴을 고려해 스케치를 주름으로 생성해준다. 또한, 얼굴 부위별 주름 형태를 분석하여 부위별 생성되는 주름의 형태가 다르고, 나이 설정을 통해 나이에 맞는 잔주름 및 주름 형태를 변형 한다. 본 논문에서 제안하는 방법을 이용한 주름 생성 방식은 주름에 대한 자세한 지식이 없는 사용자라도 간단한 스케치만 한다면 자동 계산을 통해 실시간으로 주름을 생성해주며, 얼굴 패턴에 따른 사실적인 주름이 생성되는 결과를 보여준다.

Internet Engineering Task Force(IETF) proposed the Hierarchical Mobile IPv6(HMIPv6) to support mobility efficiently. The HMIPv6 was developed to reduce the signaling overhead and delay concerned with Binding Update in Mobile IPv6. However, the HMIPv6 still need a further enhancement for supporting the real-time application because HMIPv6 only concerns with the latency resulted within a MAP For providing seemless handoff we propose a scheme that can reduce latency when Mobile Node changes a MAP. Also we compare the HMIPv6 with the proposed scheme through a analysis model.

Topological maps have drawn more attention recently because they are compact, provide natural interfaces, and are applicable to path planning easily. To build a topological map incrementally, Voronoi diagram was used by many researchers. The Voronoi diagram, however, has difficulty in applying to arbitrarily shaped objects and needs long computation time. In this paper, we present a new method for global topological map from the local topological maps incrementally. The local topological maps are created through a thinning algorithm from a local grid map, which is built based on the sensor information at the current robot position. A thinning method requires simpler computation than the Voronoi diagram. Localization based on the topological map is usually difficult, but additional nodes created by the thinning method can improve localization performance. A series of experiments have been conducted using a two-wheeled mobile robot equipped with a laser scanner. It is shown that the proposed scheme can create satisfactory topological maps.
