Recently, there are a lot of studies to use a satellite image data in order to investigate a simultaneous change of a wide range area as a lake. However, in many cases of the water quality research there is one problem occured when extracting the water quality factors from the satellite image data because the atmosphere scattering exert a bad influence on a result of analysis. In this study, an attempt was made to select the relative atmospheric correction method, extract the water quality factors from the satellite image data. And also, the time-series analysis of the water quality factors was performed by using the multi-temporal image data.

In previous studies, the dynamic resistance, which was calculated by the process variables measured at the electrode of the welding machine, and the electrode displacement were used for quality exa mination. However, in-process usage of such systems is not effective in systems that include a welding gun attached to a robot. In order to overcome such problems, we obtained and used the process variables from the welding machine timer. This would allow us to estimate real time in -process weld quality. For quality estimation, the features were extracted as factors from the primary dynamic resistance patterns, which were measured in t he welding machine timer. The relationship between the indexes and nugget size of the welds was observed through the regression analysis. Using the analyzed factors, a regression model that could estimate nugget diameter was developed. Two regression equations of the model were suggested depending on the factors, and it was showed that the model developed by stepwise method was effective one for weld quality estimation. The developed estimation model was in good linearity with the nugget diameter obtained through the experimentation.

This study attempts to understand how the perception of service quality as well as shopping motives influence on the emotional responses in store shopping, and to examine how these relevant variables influence on the store satisfaction. The 463 questionnaires were collected from the purchasers in department stores, fashion specialty stores, and national brand franchise stores. The results of this study are as fellows: 1. In regard to shopping motives, two dimensions of product motive and experiential motive were identified, explaining 47.39% of shopping motives. 2. In regard to emotional response, two dimensions of pleasure emotion and displeasure emotion were identified, explaining 65.95% of emotional responses. 3. Shopping motives led to the store satisfaction after the perception of service quality and then the experience of pleasure emotion. These related variables explained 60% of the store satisfaction. 4. The consumers of fashion specialty store showed the highest product motive, whereas the consumers of department stores showed the highest displeasure emotion in the store. As the results showed, customers' shopping motives influence their perception of service quality and pleasure emotion. Therefore, in order to stimulate shopping motives, the store environment that can give customers pleasure and opportunity to pursue various experiences should be provided. As the service quality is a very important variable that leads pleasure emotion in the store, sales persons should be trained to satisfy customers.

In order to solve water quality problem of domestic dam reservoir, many projects have been performed in a point of view to restoration of water quality. This study was carried out to evaluate the effect of release from sediment on water quality and release characteristics. Daecheong dam reservoir was investigated for two years, from 1998 to 1999. The nutrient release rates of Daecheong reservoir is less than foreign eutrophic reservoir at anoxic condition. For the evaluation of the effect of nutrient release on water quality, internal and external loading was calculated at Daecheong reservoir. As total phosphorus loading from sediment is calculated 9.3 ton/yr and inflow loading from Daecheong reservoir watershed 118 ton/yr, internal loading shows the portion of 7.88% to external loading. At this study, because sampling point was choosed at the point where much sediment is accumulated, experimental result is more than average release rates. Because Daecheong reservoir shows complete thermal stratification and anoxic condition below 30m from water surface in summer seasons, released phosphorus from sediment can not transfer to epilimnion and eventually resettles. Therefore sediment has insignificant impacts on water quality on Daecheong dam reservoir.
