In coming 21st century, which is forecasted that it will be a knowledge-information oriented society, abilities of information acquirements are required. For this, the Ministry of Education has been encouraging the business of information oriented school education and promoting application of ICT more than 10% in all classes of the 7th curriculum. Moreover, after extending applied classes into 20% by 2005, the Ministry of Education will promote editing textbooks by subjects reflecting the content of ICT application. But, actually, classes applied ICT aren't fulfilled in education fields. The main reason for this is that teachers don't understand fully ICT application model. On the basis of the preceding studies, this study designed subject-settlement class model to develop students' abilities of information acquirements. The subject-settlement class model is made up of 5 steps--confirmation of studying subjects, searching information and collecting, using information, arrangement of results, communication of information, and evaluation. By experiencing search of information, arrangement of information and creation of new information, the application of this model helps the students develop abilities of information acquirements. Nowadays, development of information communication and of computer makes the world change from information oriented society into knowledge oriented society. Future society will focus on the ability of production to create knowledge information. This study is the result presented as a part of the ability of creating information. Furthermore, the development of various learning and teaching models, which are required in information oriented age, are expected.

Abstract The analysis of arsenic in drinking water with ICP-USN method and ICP-VGA method was studied. In USN method, wavelength of 193.696nm was used and in VGA method, 228.812nm was used. The values of arsenic of same sample in each method, MDL, RPD, recovery, accuracy and precision were studied. The values of 14 sample of drinking water were within 0.05ppm or were not detected. But in one sample high value of 0.044ppm was detected. MDL of USN was 0.013ppm and MDL of VGA was 0.0004ppm. This results showed lower MDL of VGA but RPD of USN was better than VGA. Recovery of two methods was same, but accuracy and precision of USN were better than VGA. Therefore ICP-VGA method could be used according to this result(MDL) when arsenic trace element detection in drinking water should be achieved.

Korea Aerospace Research Institute (KAKI) is developing a Korea Multi-Purpose Satellite I (KOMPSAT-1) which accommodates Electro-Optical Camera (EOC), Ocean Scanning Multi-spectral Imager (OSMI), and Space Physics Sensor (SPS). The satellite has the weight of about 500kg and will be operated on the 10:50 AM sun-synchronized orbit with the altitude of 685 km. The satellite will be launched in 1999 and its lifetime is expected to be over 3 years. The main mission of EOC is the cartography to provide the images from a remote earth view for the production of 1/25000-scale maps of KOREA. EOC collects 510 - 730 nm panchromatic imagery with the ground sample distance(GSD) of 6.6 m and the swath width of 17 km by push broom scanning. EOC also can scan ±45 degree across the ground track using body pointing method. The primary mission of OSMI is worldwide ocean color monitoring for the study of biological oceanography. It will generate 6 band ocean color images with 800 km swath width and 1km GSD by whiskbroom scanning. OSMI is designed to provide on-orbit spectral band selectability in the spectral range from 400 nm to 900 nm through ground command. This flexibility in band selection can be used for various applications and will provide research opportunities to support the next generation sensor design. SPS consists of High Energy Particle Detector (HEPD) and Ionosphere Measurement Sensor (IMS). HEPD has missions to characterize the low altitude high-energy particle environment and to study the effects of radiation environment on microelectronics. IMS measures densities and temperature of electrons in the ionosphere and monitors the ionospheric irregularities at the KOMPSAT orbit.
