This paper studies the problem of fault estimation using adaptive fault diagnosis observer. A fast adaptive fault estimation (FAFE) approximator is proposed to improve the rapidity of fault estimation. Then based on linear matrix inequality (LMI) technique, a feasible algorithm is explored to solve the designed parameters. Furthermore, an extension to sensor fault case is investigated. Finally, simulation results are presented to illustrate the efficiency of the proposed FAFE methodology.

This paper reports the preliminary results on the study of radargrammetry especially for a high-resolution satellite synthetic aperture radar system. Theoretical configurations for radargrammetry in terms of coverage, orbit selection, incidence angles, height sensitivity of parallax and height resolution of DEM were calculated according to the proposed orbit characteristics and the imaging modes of KOMPSAT-5 SAR. Possible imaging strategies and mission scenarios for coverage versus rapidity are suggested for a future mission dedicated to radargrammetry.

Cardiovascular and respiratory responses of fish exposed to environmental hypoxia have on the subject of a number of investigations. Although relatively few species have been examined, generalized responses to ambient hypoxia include an elevation of blood pressure, increased systemic vascular resistance and bradycardia (Fritsche and Nilsson, 1990; Bushnell and Brill, 1991). The degree of bradycardia experienced by fish during hypoxia is highly variable and may depend upon the severity of the hypoxia and the rapidity with which it is imposed. (omitted)

An automatic TCXO frequency-temperature test apparatus was firstly developed by using thermoelectric device may. The developed system swing stably the test temperature range from -40$^{\circ}C$ to +80$^{\circ}C$ for about 1 hour The rising temperature ratio was fairly linear with time in this test temperature range. The temperature could be controlled error in error range of ${\pm}$0.05$^{\circ}C$ in this system. The frequency-Temperature properties of TCXO or the thermoelectric properties of other electric device.

The determination of total paraffin, naphthene, and aromatic (PNA) contents in naphtha samples, which were directly obtained from actual refining process, has been studied using near-infrared (NIR) spectroscopy. Each of the total PNA concentrations in naphtha has been successfully analyzed using NIR spectroscopy. Partial least squares (PLS) regression method has been utilized to quantify the total PNA contents in naphtha from the NIR spectral bands. The NIR calibration results showed an excellent correlation with those of conventional gas chromatography (GC). Due to its rapidity and accuracy, NIR spectroscopy is appeared as a new analytical technique which can be substituted for the conventional GC method for the quantitative analysis of petrochemical products including naphtha.

This research aimed at comparative analysis of body composition and basic physical strength of model majored female college students and general female college students. The research object was composed of 15 model majored female college students of D University, who learned the purpose of this research enough and wrote the consent form of voluntary participation and 15 general female college students, who have no medical history and currently no special disease, and no experience in regular exercise. They underwent body composition inspection, left right grasping power which is the basic physical strength, back muscle strength, flexibility, rapidity, muscle endurance, and the researcher performed descriptive statistics to calculate the average standard deviation, and analyzed to verify difference between groups by using independent t-test. With statistical significance level p<.05, the results are as follows. model majored female college students and general female college students showed meaningful difference between groups in weight, skeletal muscles, body fat volume, BMI and left right grasping power, back muscle strength, rapidity(p<.05). between groups in flexibility and muscle endurance(p>.05).

This study was carried out to get the basic informations regarding the varietal variations for the physicochemical properties such as protein content, amylose content, fatty acid content, grain quality values and color properties such as lightness value, chroma and hue for the 164 recombinant inbred lines(RILs) of Milyang 23 and Gihobyeo(M/G) at the experimental farm in the Sangji University. The principal component analysis and heritability study were conducted for this experiments. The rapidity of grain filling(RCF) for the 164 M/G RILs could be classified into four groups such as slow maturing group less than 41％, mid-slow maturing group 41∼60％, fast maturing group 61∼80％ and very fast maturing group more than 81％ based on the rapidity of grain filling rate. The slow maturing group of RGF showed a little bit higher protein content 9.1％, compared to the other RGF groups. However, the amylose content of all the RGF groups revealed the same content by the groups. The very fast maturing group of RGF showed longer grain length in brown rice compared to other RGF varietal groups, in case of grain width in brown rice showed shorter than any other groups. The alkali digestive value which was so much related to gelatinization temperature showed 3.40 degree at fast maturing group of RGF in M/G RILs. However, the very fast maturing group of RGF revealed 4.31 degree of alkali digestive value. The principal component analysis was performed by the chemical and color properties such as quality value, protein content, amylose content, alkali digestive value, fatty acid content, lightness value, chroma and hue for M/G RILs. The first principal component was able to explained upto 36％ to total informations. It was corresponded to quality value, protein content, amylose content, fatty acid content, lightness value and a-value(green -1 red). The characters regarding grain quality showed high heritable properties more than 75％ of heritability, but color characters appeared relatively lower heritability compared to grain quality.

Clear visualization of pepper (Capsicum annuum L.) microspore nuclei with common stains such as acetocarmine or propionocarmine is difficult, hindering cytological analysis. The DAPI stain after the addition of ferric chloride solution to fixative resulted in clear visualization of nuclei. For clear visualization of nuclei and slight fluorescence of microspore wall, addition of 40-60 ${mu}ell$ of ferric chloride solution to the 1 $m\ell$ fixative was identified as most effective. At all stages of gametophytic development, the nuclei can be distinctly visualized. Starch granules does not intefere with the fluorochrome, and so the vegetative and generative nuclei were cleary visible in binucleate pollens. With its rapidity and reliability, this technique represents an efficient tool for routine staging or investigation of the nuclear status of the microspore during culture.

A brief description on the greenhouse gases, the greenhoue effect, sea level changes, forcing of climate, the history of Earth's changing climate based on the IPCC REPORT and the records of the recent variation of the climate in the Republic of Kore is presented here for help enhancing awareness of the issues. The climate of the Earth has the potential to be changed on all timescales by the fluctuations of the concentrations of radioactively active greenhouse gases, solar radiation, aerosols and albedo. However, the rate of the recent global warming seems to be larger and rapid than any have occurred thorughout recorded history enough to draw the world-wide attention and worry concerned with the theme of environment and development. There are still uncertainties in the predictions relating to the timing, magnitude and the pattern of the climatic change due to the current incomplete understanding of various aspects of the complex processes. Nonetheless, the scientific results avaliable is sufficient to allow for decisive precautionary measures to be taken.

The purpose of this study is developing a disaster prevention information system using Internet GIS to manage disaster information more efficiently and timely. This system has good potential with environment of Internet which has appropriate characteristics of rapidity, wide reach, generality, cost effectivity for disaster management. With this system, general user can easily retrieve disaster information with visuality such as maps. graphs, and texts just by using web browsers. Hence the need of developing Internet GIS system for disaster prevention is growing in these days.
