The purpose of this study was 1) to find out the benefits sought factors of jeans and to segment the consumer market 2) to analyze Purchase behavior, brand loyalty, and demo- graphic characteristics of benefit segments. The subjects were 350 male and female university students who have purchased at least one of the nine jeans brands selected for this study. For statistical analysis, reliability test, percentage, factor analysis, cluster analysis, x2-test, and analysis of variance were used. The results of this study were as follows; 1. Benefits sought by consumer were found to include four different factors-brand value, individuality, fashionability, and practicality. 2. As a result of subdividing the consumers, three distinctive groups were formed on the basis of benefit factors-individuality.fashion oriented group, brand value oriented group, and practicality oriented group. 3.

The questionnaire consisted of brand preference, attribute of brand image and wearer image was selected from the previous studies or developed for this study. The subjects were 350 male and female university students who have purchased at least one of the nine jeans wear brand selected for the study. For statistical analysis, reliability test, factor analysis, MANOVA, and multiple regression were used. The results of this study were as follows: 1. Symbolism, quality, and economy were found out as constricting factors of brand image in the attribute dimensions, while innovative and active image were found out in the wearer image dimensions. 2. 9 Perceptual maps of attribute dimensions and 3 perceptual maps of wearer image dimensions were constructed and each ideal vector was drawn.

For statistic analysis, percentage, average, ANOVA, x2-test, Duncantest, paired t-test, and multiple regression were used by SAS package. The results of this study were as follows. 1) Consumers were classified into affective brand loyalty group, familiar brand loyalty group, habitual brand loyalty group, brand interest but no brand loyalty group, and no brand loyalty group. 2) There were notable differences in clothes purchasing behavior variable through market segments' purchasing (requency, price. 3) The most Prefered jean Product is 80,000 won, domestic well-known brand, baggy style and preferable jean product shows different when it classified brand loyalty.d loyalty.

This paper concerns the Holocene environmental change with vegetational history and sea-level fluctuation at Ilsan area by the analytical data of pollen, sedimentary facies and $C^14$-dating. The hypothetic palaeogeographic maps of the vegetation cover have been reconstructed with the reference to the periods of pollen zone. The environmental characteristics from the pollen zonation have been summerized as follows. 1)Pollenzone I(3.75~5.75m) showed the period of Alnus-and EMW-dominance. The study area was very humid under the influence of the transgression spreading widely from the rapid sea-level rise during the period(8,000~4,200y.BP). 2)Pollen zone II(5.75~6.35m) has been influenced by the fall of the sea-level and ground water surface. This zone(4,200~2,300y.BP) represented the period of spore~ and NAP-dominance with the increase of Pinus. 3) Pollen zone III(6.35~6.55m) has reflected the influence of the transgression and human interferences together. This zone(2,300~1,800y.BP) represented the period of NAP-dominance. The boundary between Subzone Ilb and Pollen zone III represents the same characteristics as what Weber says Grenzhorizont.

It is difficult to analyze pymetrozine in citrus fruits using the hydromatrix method because of its low efficiency of purification and overlap of matrix and pymetrozine peaks. Liquid-liquid extraction can analyze pymetrozine in citrus fruits using dichloromethane. Since low pH interferes with the extraction of pymetrozine, the extracts of citrus fruits were maintained over pH 7.0 by adding borax buffer and 1 N NaOH in the improved method. According to the improved method, citrus fruits (such as lemon, lime, orange, tangerine, and grapefruit) were extracted and purified for HPLC-photo diode array analysis. The results of validation were as follows: $4.360{\mu}g/kg$ of limit of detection, $14.533{\mu}g/kg$ of limit of quantitation, and 0.007 mg/kg of method quantitative limit. Citrus fruits spiked with pymetrozine showed a recovery range from 71.8 to 83.7% and a coefficient of variation below 6%. Thus, the improved method can efficiently analyze pymetrozine in citrus fruits.

The aim of the study is to develop a jean jacket and pants of easy-to-move for schoolgirls of 11 years old. The research was carried out as follows; 1. Using a manufacturer's pattern, a jean jacket and pants were made. 2. Based on the survey of 108 schoolgirls, interviews with 4 designers of children's wear, and wearing test, three trial garments were developed. -Certain areas such as knee, elbow, and hip should be altered to have better extensibility. -The weight of the garment would be better to be reduced. 3. Three trial garments were developed using following techniques, which were found in fashion magazines for kids very often. -Alter the location and the shape of the seam line so that the areas mentioned above can adjust the movement of the body better. -Match stretchable material at the areas which require better extensibility. -Use various trimmings to make the garment more size adaptable and easy-to-move. 4. These garments were tested by 26 schoolgirls, and they answered the questionnaires focused on the design preference and easy-to-move. 5. From the results of the wearing test of three trial garments, more effective techniques were selected. Using these techniques, prototype garment was developed. The prototype garment was approved by the wearing test of 26 schoolgirls.

This study was intended to examine the effect of consumer materialism, price and point-of-purchase advertisements on consumer preference and purchasing intention with respect to discount jeans. Information for the study was obtained through the use of an experimental design which was 2$\times$[2$\times$3] mixed factorial design. The subjects were two hundred and seventy college male and female students. The data were analysed with factor analysis, ANOVA by using the SAS program. The main results were as follows: First, the results indicated that the 3-way interaction effects among materialism, price and point-of-purchase advertisements on consumer preference. Second, the results showed the 2-way interaction effects between materialism and price between materialism and price on consumers’purchasing behavior. These results indicated that materialism have not direct effect on consumers’purchasing behavior but significant influence under those condition in which price effect occurs.

This study also analyzed the major factors in purchasing jeans for 17-29 age groups. The 660 questionnaires were distributed and 618 reliable ones were used for statistical analysis. A SAS statistical package including frequency' table, Chi-square test, factor analysis, analysis of variance(ANOVA), Duncan's multiple range test was used. The results of this study showed that consumer possessed about 6 pairs of jeans and bought about 3 pairs of jeans per year. The most recently purchased brand was Nix. Lots of brands were statistically significant at the segmented three age groups and in the five different distribution regions. The most popular type of design was the basic style.
