We investigated a trait of odor and the relationship between odor unit and odorous compounds using multiple regression analysis based on data compiled from Sihwa (SIC), Banwol (BIC), Banwol plating (BPIC) and Poseung industrial complex (PIC). These areas are odor control areas in Gyeonggi province. It was revealed that $NH_3$ and styrene concentrations in SIC and BPIC were relatively higher and $H_2S$ concentration especially in mc was more than five times higher than other areas. As a result of regression analysis using SAS, intensity of odor unit was highly related to concentrations of $H_2S$, TMA, styrene and n-valeraldehyde in SIC, $H_2S$, acetaldehyde, and butyraldehyde in BPIC and $NH_3$ in BIC.

In the present research work was searched the influence of severe plastic deformation (SPD) realized by ECAP (equalchannel angular pressing) on structural, mechanical and plastic properties of IF (interstitial free) steel. For physical simulation ECAP process with right angle channels $(90^{\circ})$ was used. The ECAP process was numerical simulated (namely its course of temperature, strain and stress fields and deformation forces) by FormFEM software, too.

In spite of the importance of the farm area in Seoul, in providing fresh vegetables, a pleasant environment and a good quality of life for residents, rapid urbanization and industrialization have greatly reduced the farm area. The purpose of this study is to examine farmers' intentions and attitudes to provide supporting data for planning the strategy of urban agricultural development. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. Farmers' views on the farming in Seoul were different depending on their status. Therefore, agricultural strategies in there should be considered their different attitudes.

Quick response in the textiles and clothing industry is widely recognized at a strategic concept implemented by information technology to transfer changes in customer needs to the final product as soon as possible. This paper addresses which factors should affect the adoption of quick response systems in Korea. We surveyed 108 companies in the textile and clothing industry by using a questionnaire. We asked whether they adopted QR or not, and measured the usage level of QR-related ITs and the level of both internal and external factors in Likert's scale. We conducted multiple linear regression to analyze the data collected by using SAS. The findings are as follows: The adoption of QR, measured by the usage level of QR-related ITs, is positively affected by internal factors such as the recognition of QR concept and the capability for IT applications and by external factors such as the overall informating level of the industry, the needs for cooperation between organizations, and the leadership as an industry coordinator.

The purpose of this study was to examine the tendency of demands and satisfaction according to the resident's characteristics using the Cognitive Measurement Scale of Residential Life Management. Data were analyzed by the SAS program package. The results of study showed that the degree of satisfaction in the life management was low. And highest demand of each factor was as follows : Life cooperative association in Fesidential life convenience service(I). Bank service in Residential life support service(II). Announcement about utility fee in Resident's activity support and announcement of managerial warks(III). Works about criminiality control in Safety and order sustaining(IV). Care for empty house in Precaution to accident(V).

The purposes of this study were to define the current status of information infrastructures and electronic information retrieval systems in university libraries in Korea, to assess the impact of information technology on library collection development in Korea universities, and to determine the relationship between electronic information retrieval service and library collection development. Data was collected by a mail survey. Questionnaires were mail in December, 1997 to all 134 4-year university libraries. Approximately 78 percent of the questionnaires was returned. The data taken from the survey instruments were analyzed with the analysis of variance(ANOVA) test of SAS program.

In spite of the importance of the farm area in Seoul, in providing fresh vegetables, a pleasant environment and a good quality of life for residents, rapid urbanization and industrialization have greatly reduced the farm area. The purpose of this study is to examine farmers' intentions and attitudes to provide supporting data for planning the strategy of urban agricultural development. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. Based on analysis of the survey data, the leaseholders were found to be more satisfied with their job than the landowning farmers. Also, the small-scale farmers with green houses showed greater job satisfaction than the ordinary large-scale farmers. Farmers' views on the farming in Seoul were different depending on their status. Therefore, agricultural strategies in there should be considered their different attitudes.

The purpose of this study was to compare nutritional intakes of college students in Seoul and Yanbian by ethnic : Korean, Korean-Chinese, Chinese. The questionnaire were applied to individual interviewing method. Statisticai data analysis was completed by SAS 8.0 package program for t-test, ANOVA and multiple comparison. The results of this study were as follows. Average energy intake per day was high in Korean-Chinese. Nutrient Adequacy Ratio(NAR) was highest in iron and lowest in zinc. Mean Adequacy Ratio(MAR) score was $0.68{\sim}0.85$ for each group. The indexes of nutritional quality(INQ) were over 1.0 for most nutrients except 0.41 of zinc and 0.76 of calcium. Average energy intake ranked high in Korean-Chinese, Korean and Chinese.

This study was attempted to segment the male consumers' market for men's suit based on brand preferences and to identify the group differences in apparel purchasing behaviors and demographic features and to suggest basic information applicable to marketing strategy. 705 men were selected for the study; they were in their twenties through forties, and they lived in Seoul and its suburbs. 655 survey questionnaires were collected and used for analysis. Using the SAS package, frequency, factors, reliability, correlation, genealogical group analysis, distribution analysis, the ($\chi$$^2$-test and the Duncan test for verification were actualized for analysis. The findings of this study were as follows: First, male-suit consumers tend to prefer the national brand(61.07%), licensed brand(19.39%), volume character brand(7.63%), prestige character brand(6.56%), and directly imported brand(5.34%) in order. Second, there were significant differences in apparel shopping orientations, purchasing behavior variables and demographic variables among the 5 classified groups.

This study was conducted to develop regression models predicting sugar and acid contents in intact fruits nondestructively by using the second derivative of absorbance spectrum measured with a spectrophotometer wavelength range of 400nm to 2, 400nm. The correlation analysis was made in wavelength range of 600nm to 1, 100nm and 600nm to 2, 400nm respectively, in order to examine the feasibility of using a real time spectrophotometer, which covers the former range, in predicting sugar and acid contents. The second derivative data of the spectrum were obtained by varying smoothing size and derivative size of the original absorbance spectrum. SAS statistical package program was used for the regression analysis. The sugar contents of Fuji apple, Shingo pear md Yumyung peach could be predicted with SEPs of 0.40, 1.17 and 0.77 respectively, in the spectrum range of 600 to 1, 100nm. The highest correlation coefficient of the titratible acidity of apple was -0.45 at 2, 346nm and regression models indicated determination coefficient less than 0.47.
