Adaptive control in the robotic GMA(Gas Metal Arc) welding is employed to monitor the information about weld characteristics and process paramters as well as modification of those parameters to hold weld quality within the acceptable limits. Typical characteristics are the bead geometry composition micrrostructure appearance and process parameters which govern the quality of the final weld. The main objectives of this paper are to realize the mapping characteristicso f penetration through the learning. After learning the neural network can predict the pene-traition desired from the learning mapping characteristic. The design parameters of the neural network estimator(the number of hidden layers and the number of nodes in a layer) were chosen from an error analysis. partial-penetration single-pass bead-on-plate welds were fabricated in 12mm mild steel plates in order to verify the performance of the neural network estimator. The experimental results show that the proposed neural network estimator can predict the penetration with reasonable accuracy and gurarantee the uniform weld quality.

The purposes of this study were to investigate component of service quality and to determine significant factors on the service quality and buying intention of internet apparel shopping mall. The data were collected from 212 female adults using questionnaire. Using SPSS package, Cronbach's α, factor analysis, and multiple repression analysis were performed. The results could be summarized as follows. 1. The service quality of internet apparel shopping mall was perceived as reliability, advantage, responsibility, product assortment, tangibles, and rapidness. 2. For perceived risk, privacy risk, economic risk, delivery risk, size risk, and quality risk were investigated. The perceived risk except economic risk and web search ability had an effect on the service quality of internet apparel shopping mall. 3. The most of perceived risk, web search ability, and advantage of the service quality had an effect on the shopping intent of the internet apparel shopping mall. Based on the these results, marketing strategies were suggested.

Using the acetate velvet and viscose velvet whose pile lengths were sheared as 1.45, 1.55, 1 65, 1.75, 1.85, 1.90mm under the condition equating the weaving process of ground fabric, the conclusions were as follows through the results of the sensory assessments estimated by women students in our university and the physical properties, H. V and T. H. V obtained by KES-F system. 1. In the sensory assessments estimated by the method of paired comparison and ranking of samples, the longer pile length was, the more the hand values of smoothness, softness, thickness, heaviness increased on the whole. 2. The H V. and T. H. V. measured by KES-F system were as follows; Kohi increased to pile length 1.85mm and then decreased a little at 1.90mm. hummer increased as pile length was longer. Fukurami increased to pile length 1.75mm and then decreased gradually as pile length was longer. Total hand value increased gradually from 1. 45mm to 1.85mm, had the top value at 1.85mm, and then decreased a little at 1.90mm. 3. In the results of summarizing $\ulcorner$the physical properties correlated closely with the H. V obtained by sensory assessments$\lrcorner$ and tithe Physical properties correlated closely with the H. V. and T. H. V obtained by KES-F systems, it showed that all the sensory properties correlated closely with compressive energy, flexural rigidity, thickness, weight and pile ratio in the former and that the physical properties correlated closely with each H V and T. H. V were different in the latter. 4. It showed that factor 1 was related to compressive energy, thickness, weight, pile ratio, factor 2 was related to recovery energy, compressive resilience, compressive index, and factor 3 was related to compressive recovery ratio in the result of factor analysis. 5. In the multiple repression analysis, the expressions of all sensory properties had compressive ratio, frictional coefficient in the regression expressions of $\ulcorner$H. V. obtained by sensory assessments$\lrcorner$, while the expressions of each H. V. and different physical properties in the regression expressions of $\ulcorner$H. V. obtained by KES-F system$\lrcorner$.

The aim of this study is to compare open space planning between Australia and Korea by Local Governments Areas. Open space planning is carried out at the state and municipal level in Australia, but by metropolitan city government in Korea. This study is structured by reviewing the presemt phenomena of provision of open space in Sydney and Seoul, By measuring disparity in terms of open spaces by L. G. A. s an by comparing planning approaches between two cities, for example policy, government standards, government administration system in open space management. In this paper, the provision of parks in Sydney and Seoul are comparatively examined and geographically mapped, and multiple repression analysis is applied to measure the residuals from the line of equality. The results of this study show that, 1) During the last 1 dacade from '80 and '90. Sydney has increased the quantity of open spaces from ratio of 19.11ha/1000 to 22.33ha/1000 of parks, however Seoul decreased it by the ratio of 12.21$m^2$/person to 1012$m^2$ per person. 2) Sydney has more programs, such as Greenspace program, Metropolitan open space program etc. to increase and to distribute open spaces equally rather than Seoul which has less open spaces. 3) There exists patterned inequality in terms of open space provision in inner city and suburb between Sydney and Seoul. 4) Seoul requires more active polices to increase open spaces like Greenacre Program of New Jerrsey State, Double Open Space Pland of Tokyo or Green Space Program of Sydney.

This study has tried to illuminate a shocking phenomenon, the import liberalization of agricultural products in the aspect of Consumer consciousness. It has been applied that Table Analysis by using computer programming for instance-MINITAB, and Correlation Analysis and Multiple Regression Analysis, things like that. The results of this study are as follows; 1. Comparing domestic and imported stuffs, Comsumers came to awareness that domestic products superior to foreign's in the cases of the degree of freshness, taste and pollution damage, in the meanwhile, inferior to the cases of price and wrapping. Food self-supplyment is considered as one of the most important things of all, moreover, by most comsumers and health food and conventional food are favored by high class people. 2. Bying imported stuffs could clearly be fatal blow to our agriculture is fully recognized among consumers, what is more, there would only be doomed to our agriculture, too. 3. The most mass-purchasing imported stuffs by consumers illustrates in order; Beef, Banana, Coffee and Tabacco etc. The most significant elements why consumers buy foreign product is that the prices of them are relatively lower than those of ours. Besides, the next causes lies to non-producing stuffs and curiosity. 4. It must've been generally conceived by most consumers that Open-the-market-policy has been progressed for USA's repression and our monopolistic capital. Therefore, they demand that our market should be contained against unadviciable wave, moreover, keep paying attention to the policy how it will work to protect Korean agriculture. 5. Consumer attitude toward buying imported agricultural products is double-faced, Never-buy occupied only 24.4 % among respondents, but overwhelming respondents say non-producing stuffs can be obtained selectively. In this case, however, never-buy-movement would be backed by consumers in proportion to their educational background. 6. Various consumer minds surrounding Open-the-market-situation, in the end, has been analized econometrics through eleven variables to approach accurate fulfillments.
