Synthetic aperture radar(SAR) has been widely used for reconnaissance. It provides high-resolution, day-and-night and weather-independent images for a multitude of applications. Because SAR coherently combines many viewing angles to effectively create a large aperture(narrow beam) radar, the test-bed should be capable of moving straightly SAR sensor for the integration angle to meet resolution. This paper describes the test-bed developed to test and evaluate the SAR performance. It forms high-quality images in real time and saves the raw data for the purpose of post processing on the ground.

Combustion of RDF and wastewater sludge was performed in a 0.1MWth bench scale circulating fluidized bed combustor(CFBC), Combustion characteristics of the RDF and sludge mixture demonstrated stable combustion conditions. Component analysis, Combustion characteristics was measured before and after the test, and applications for commercial 1MWe CFBC boiler were prepared. The release of hazardous components such as $SO_2$ and HCl was relatively low values of 50 and 150ppm, respectively.

Recently, the users of internet are increasing yearly with the rapid spread of internet. So, the shortage of IPv4 address is important issue to ISP. Many ISP is searching for efficient method to use IP address in ATM Network. Korea Telecom has constructed ATM Network test-bed to verify available technologies necessary for ATM Network. This paper, concerning with the configuration of subscribers in ATM Network test bed, analyze the available usage of IP address.

Technological progress in integrated, low-power, CMOS communication devices and sensors makes a rich design space of networked sensors viable. These sensors can be deeply embedded in the physical world and spread throughout sensor network environment like smart dust. So ubiquitous computing will be come true. SmartDust project is the one of ubiquitous computing approach. It produces TinyOS, mote(mica, mica2, rene2, mica2dot, etc.), NesC, TinyDB, etc. We constructs sensor network test bed and tests to approach sensor network and ubiquitous computing.

Tidal current energy is the most interesting renewable resources that have been less harnessed. Korea has globally outstanding tidal current energy resources and it is highly needed to develop a tidal current energy conversion system. It is reported that the total amount of available tidal current energy is approximately 6GW in Korea. A good tidal site candidate is required a large amount of fast moving water, bathymetry and seabed properties, no conflicts with other users and is close to a load and grid interconnection. In this review, we summarized the results of R&D projects regarding tidal current resources, utilization projects and demonstration test bed.

The practical route for disposal of sewage sludge becomes energy recovery by combustion after its ocean dumping is banned in 2012 in Korea. Due to the high moisture content, however, sewage sludge is required to be dried before transport and combustion. In this study, pyrolysis and combustion characteristics of dried sewage sludge was investigated in a small-scale fixed bed reactor in order to provide fundamental data for energy recovery of the fuel. As the first step of combustion, the primary products of pyrolysis were analyzed in a fixed bed reactor for the condensable volatiles (tar), non-condensable gases, and char. For the combustion characteristics, another fixed bed reactor was constructed to monitor the weight and temperature of the fuel particles during ignition and combustion under different air flow rates. The test results were used to derive the ignition and burning rates.

In general, the function of university dormitory includes residental, educational and many other functions for students who need quite environment and energetic living life. Among these many functions, the most important function is residental function (bed room). This study attempts to evaluate the bed room environment of four university dormitories in north region of Gyeongbuk Province using resident's (students) need and satisfaction. In the present work, SPSS window version12.0 program's Anova (duncan, scheff, t-test.) was used for analysis of statistical data which obtained from survey. The field surveys carried out for a total samples of 473 residents such as AD (118), DY (159), Kw (101) and SJ (95)) types of bed room in four university dormitories. The result appears that the most dissatisfied factor of resident was personal privacy, and the most satisfied factor was the direction (location) of bed room space.
