This technology is based on the processing skills by the automatic high speed burner processors to improve the overall productivity and customer satisfactions. The following conclusions could be gained from this research. A burner for processing stone plate was measured to obtain the average 23.8 m/s. Non-slip friction coefficient of the burner after processing was measured to obtain a mean value of 53.2 BPN. Production rate for stone items was measured by the time of the burner and the result passed through the brush was 26.94 m/s on average.

In the world economy and the shipping industry, container, bulk carriers and oil tanker vessels are undergoing a bigger difficulty because of the imbalance on supply and demand with the view that ship's loading capacity is exceeded. For this reason, shipping companies are trying to reduce the operating cost through slow steaming. Thus, under this condition of continuous recession in shipping industry, saving on fuel consumption is the main issue. In this study, tests were conducted to find out the method of reducing fuel oil consumption by economically operating the ships, taking into account the main engine power and speed. The subject vessel's fuel consumption compared to the output is lower near the range of 138~157RPM. The engine speed showed significant increment to 144RPM and fuel consumption increased rapidly compared to the engine speed at 15knots and above. During sea trial test, the subject vessel's specific fuel rate(SFR) was 134.25[g/BHPh] while the calculated value after 10 years of operation is 137.1[g/BHPh] at speed range of 148~150RPM which is 70% of the load and this indicates an increase of approximately 2.1%.

We present a multi-dimensional reduction method of the surveyed cube database obtained using a single- dish radio telescope in Taeduk Radio Astronomy Observatory (TRAO). The multibeam receiver system installed at the 14 m telescope in TRAO was not optimized at the initial stage, though it became more stabilized in the following season. We conducted a Galactic Plane survey using the multibeam receiver system. We show that the noise level of the first part of the survey was higher than expected, and a special reduction process seemed to be definitely required. Along with a brief review of classical methods, a multi-dimensional method of reduction is introduced; It is found that the ‘background’ task within IRAF (Image Reduction and Analysis Facility) can be applied to all three directions of the cube database. Various statistics of reduction results is tested using several IRAF tasks. The rms value of raw survey data is 0.241 K, and after primitive baseline subtraction and elimination of bad channel sections, the rms value turned out to be 0.210 K. After the one-dimensional reduction using ‘background’ task, the rms value is estimated to be 0.176 K. The average rms of the final reduced image is 0.137 K. Thus, the image quality is found to be improved about 43% using the new reduction method.
