In this study, a new method for quantitative and efficient measurement for the ground surface movement was developed. The feature of this technique is to identify geomorphic characteristics by image matching analysis, using the intelligent images made from high resolution DEM(Digital Elevation Model). This method is useful to extract the small ground displacement where the surface shape was not intensely deformed.

An annealing process was developed for the practical reco.er of a purified py-rolytic carbon (PPyC) surface from damage, such as co.or change and peeling, due to fluorination during exposure to chlorine trifluoride gas at high tempera-tures for the cleaning of a silico. carbide chemical vapor deposition reactor. The PPyC surface was annealed at 900°C for 10 min in ambient nitrogen co.-taining oxygen at the co.centrations of 0.01% - 20%. The rainbow-like co.ored surface returned to the dark gray co.or of the original PPyC. Simultaneously, the thin peeled films disappeared. The Raman spectra showed that the PPyC surface chemical bonding returned to that of the original one. The oxygen co.centration as low as 0.01% co.ld reco.er the PPyC surface along with re-ducing the surface pit formation, when the co.bination of the exposure to chlorine trifluoride gas and the reco.ery was repeated.

Technical co.mittee for Japanese industrial standard of heat treating oils has studied on the new method for testing co.ling power of aqueous quenchants. This method employed the co.ling curve test of a new sliver rod probe, which has a metal-sheathed thermoco.ple at its geometrical center. The experimental study has clarified that this probe has the higher sensitivity and excellent durability. In order to standardize this probe for co.ling power test of aqueous quenchants, the repeatability and reproducibility of test results etc. have been studied. D.O.P. (Di-2-ethylthexyl Phthalate) was used as reference quenching fluid for initial calibration and for periodic calibration verification of the probe and system. In addition, 10% brine was used to check the response capability of the probe and system to the sudden change of temperature. These procedures are established acco.ding to the experimental investigation. This new test method is going to be built in the revised version of JIS K 2242 "Heat treating oils" as the co.ling power test method for aqueous quenchants.

The latest publications regarding the development of technology to co.trol inclusion co.positions focusing on MgO?Al2O3 spinel inclusions were summarized in this review article. The problems caused by spinel inclusions, which affect practice as well as products were shown. The formation mechanism of MgO?Al2O3 spinel inclusions is seco.dly explained thermodynamically from the view points of chemistries of molten steels and slag co.positions. Furthermore, crystallization behaviour of spinel was introduced. co.ntermeasures co.ducted in practices and laboratories were shown along with some problems still left that should be solved in the future.

A model in which a river model was layered on a distributed model （double-layered model） was developed to analyse the transport of water and pollutants （nitrogen, phosphorus, and BOD as organic matter） in watersheds and rivers. The model was applied to the watershed of Abragafuchi Lake, Japan, where serious water pollution has occurred over three decades, and the applicability of the model was demonstrated. Scenarios of recycling of sewage treated-water into agriculture to reduce pollutant load discharged into the lake were analysed. The results showed that irrigating paddy fields with the sewage-treated water co.ld co.tribute to co.serving water and reducing pollutant load, with reduction rate in BOD, nitrogen, and phosphorus ranging from 6%-36%, 16%-46%, and 18%-51%, respectively. Particularly, the results indicated that, irrigating paddy fields with the treated water during non-cropping periods and the acco.panying reduction in withdrawn water from the river were more effective in reducing pollutant loads discharged into the lake. Further study is required on the effect of recycled water on crop cultivation and soil co.ditions for safe implementation.
