In this study, we selected the most effective interpolation method using both the data of sounding the depth of submarine topography and volume-production computer program. After processing the data by volume-production program, and then we selected the most effective interpolation method which nearest actual value of dredged soil quantity. Thus, these interpolation could be used for describing the optimal submarine topography.

배출된 대기오염물질은 기상조건에 따라 농도가 크게 달라질 수 있으며 이러한 현상을 규명하기 위해서는 지상 및 상층기상 관측이 필수적이다. 본 연구에서는 서울지역의 발생가능한 대기오염상태를 판단할 수 기법을 개발하고자 고도별자동기상관측기(SODAR/RASS)로 측정한 고도별 풍향ㆍ풍속, 기온등의 매시간 자료를 분석하였다.(중략)

In this paper we propose a method of representing emotional experessions and lip shapes for sign language communication using 3-dimensional model. At first we employ the action units (AU) of facial action coding system(FACS) to display all shapes. Then we define 11 basic lip shapes and sounding times of each components in a syllable in order to synthesize the lip shapes more precisely for korean characters. Experimental results show that the proposed method could be used efficiently for the sign language image communication between different languages.

로케트가 비행중 취득하는 각종 정보를 PCM / FM 방식으로 지상국으로 전송하기 위해서는 센서의 출력값을 원하는 범위의 값으로 맞추어주는 신호조절기, Analog 신호를 Digital Code로 변환 시켜주는 PCM 부 호기 및 PCM 부호기 출력을 변조시키는 송신기 등이 필요하다. 본 논문에서는 과학관측 로케트에 탑재할 PCM 부호기를 설계 제작하였고 실제 비행 시험을 통하여 만족할 만 한 결과를 얻었다.

It is realized that the extraterrestrial matter is in ionized state, plasma, so the matter of this kind behaves as not expected because of its sensitiveness to electric and magnetic fields and its ability to carry electric currents. This kind of subtle change can be observed by an instrument for the magnetic field measurement, the magnetometer usually mounted on the rocket and the satellite, and based on the ground observatory. The magnetometer is a useful instrument for the spacecraft attitude control and the Earth's magnetic field measurements for the scientific purpose. In this paper, we present the preliminary design and the test results of the two onboard magnetometers of KARl's (Korea Aerospace Research Institute) sounding rocket, KSR­III, which will be launched during the period of 2001-02. The KSR-III magnetometers consist of the fluxgate magnetometer, MAG/AIM (Attitude Information Magnetometer) for acquiring the rocket flight attitude information, and of the search-coil magnetometer, MAG/SIM (Scientific Investigation Magnetometer) for the observation of the Earth's magnetic field fluctuations. With the MAG/AIM, the 3-axis attitude information can be acquired by the comparison of the resulting dc magnetic vector fields with the IGRF (International Geomagnetic Reference Field). The Earth's magnetic field fluctuations ranging from 10 to 1,000 Hz can also be observed with the MAG/SIM measurement.
