The purpose of this study was to examine the differences in image perception, and to investigate the differences in age and income inferences according to the wearing of accessories with black dress. A quasi-experimental method was used for this study. The experimental design was a $2{\times}3{\times}3$(necklace${\times}$earrings${\times}$corsage) factorial design. The subjects were 610 female college students residing in Seoul. The model in the stimulus photographs was a woman with straight long hair. She wore a black one-piece dress with round neckline and short sleeves. The findings indicated that the wearing of a necklace enhanced individuality, attractiveness, and cuteness in women. Professionalism and individuality were heightened when she wore an earring. The red corsage enhanced individuality, but it had a negative effect in professionalism. As for the effect on interaction, attractiveness was more highly perceived when both necklace and large earrings were worn without a corsage. The absence of both necklace and earrings led to a low perception of professionalism, attractiveness, and individuality. The wearing of a necklace was more strongly linked to older age and high income than not wearing it, and it was perceived as more youthful if earrings were not worn. As for interactions, the wearing of small earrings and a red corsage was linked to the oldest age.

This study examined the influence of self-regulatory resource depletion and self-regulatory modes on fashion product purchase intention. Initial research design dealt with differences of the resource depletion effect according to self-regulatory modes. The study used a 2 (self-regulatory resource depletion: depletion/non-depletion) ${\times}$ 2 (regulatory mode: assessment mode/locomotion mode) between-subjects factorial design. Second, the research design empirically analyzed the influence of self-regulatory resource depletion and self-regulatory mode on the fashion product purchase intention by each product group divided by type and involvement of fashion product. The subjects for the initial research were 255 university students in Seoul, Gyeonggi, and Daejeon. The subjects for the second research were 873 university students in Seoul and Daejeon. Collected data were analyzed with SPSS statistical package with reliability analysis, t -test, analysis of variance (ANOVA), and analysis of covariance (ANCOVA). The results were as follows. First, assessment-oriented consumers showed low purchase intentions about fashion products when self-regulatory resources were exhausted than when self-regulatory resource were not exhausted. Locomotion-oriented consumers, indicated no differences in purchase intention about fashion products regardless of self-regulatory resource depletion. Second, influences on purchase intention by self-regulatory resource depletion and self-regulatory mode were different according to the fashion product group. The results of this study implied that strategies should be differentiated when establishing a fashion industry marketing strategy according to the self-regulatory resource depletion and self-regulatory mode of consumers.

The purpose of this study was to find out the various impressions that tone-on-tone coloration of shirts and ties gives. This experiment was based on the $2{\times}4{\times}4{\times}2$ factorial design: colors(red and blue), shirt tones(vivid, light, dull, and dark); tie tones(vivid, light, dull, and dark) and perceivers' gender(male and female). The materials in the experiment developed for this study were composed of 32 upper body photographs which were color printed and 27 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate the impression. We unified those colors of shirts and neckties, and then made shirt and necktie tone different. The subjects of this research were 192 male and 192 female college students in Gyeongnam province including Jinju City The data was analyzed by using SPSS program. Analyzing methods were one-way ANOVA and LSD test. The items of the adjectives were classified into 5 impression dimensions - potency, activity, attractiveness, visibility and tenderness. All the image by the match of shirt and tie could be possible to make various images by the color, the shirt tone and the tie tone. Blue was given more effective potent image, vivid or light tone shirt in blue was the active image. As shirt and tie had different tone, regarded as the attractive image. Vivid tone tie was evaluated the visible image, light tone shirt is the tend image.

This study investigated the effect of brand history, congruity between country of origin and conspicuous consumption of fashion brand, based on the evaluation of customers. The factorial design was constructed as a 3-way mixed design: 2(brand history: presented vs not presented) ${\times}$ 2(congruity between Country of Brand(COB) and Country of Manufacture (COM): congruent vs incongruent) ${\times}$ 2(conspicuous consumption: high vs low). A total of 302 men and women aged above 30 and living in Seoul or within the capital area, were enrolled as subjects. Of these, 26 insincere responses were excluded and a final total of 276 responses were used in the analysis. The statistical analysis included reliability analysis, three-way ANOVA, and simple interaction effect analysis with SPSS 18.0 statistics. Our results indicate that brand history, congruity between COB and COM, and conspicuous consumption had significant effect on the fashion brand preference of consumers. Furthermore, presenting the brand history resulted in higher brand preference. Second, the brand history and conspicuous consumption had a significant interaction effect on brand preference. Consumers with higher conspicuous consumption showed significantly higher brand preference than those with lower conspicuous consumption. Third, congruity between COB and COM and conspicuous consumption had a significant interaction effect on brand preference. However, when COB and COM were dissimilar no significant effect of conspicuous consumption on brand preference was observed.

The optimum alkali pretreatment parameters (reaction time, reaction temperature and potassium hydroxide concentration) for facilitate the conversion into fermentable sugar (glucose) from steam exploded (severity log Ro 2.45) barley husk were determined using Response Surface Methodology (RSM) based on a factorial Central Composite Design (CCD). The prediction of the response was carried out by a second-order polynomial model and regression analysis revealed that more than 88% of the variation can be explained by the models. The optimum conditions for maximum cellulose content were determined to be 201 min reaction time, $124^{\circ}C$ reaction temperature and 0.9% potassium hydroxide concentration. This data shows that the actual value obtained was similar to the predicted value calculated from the model. The pretreated barley husk using acid hydrolysis resulted in a glucose conversion of 94.6%. This research of steam explosion and alkali pretreatment was a promising method to improve cellulose-rich residue for lignocellulosic biomass.

This study evaluated three forces (lifting, pushing and twisting) required to maneuver the single-wheel barrows according to handle height, width, horizontal angle and vertical angle. The four independent variables were varied in two levels. Handle height was varies in two levels : 'knuckle height (KH)' and 'KH + 0.1 ${\times}$ stature'. The two handle widths were '1.5 ${\times}$ shoulder width (SW)' and '1.75 ${\times}$ SW'. Two angles of $0^{\circ}$ and $15^{\circ}$ were used for horizontal and vertical angles. The 24 factorial design was used in the experiment. Twelve healthy male students (undergraduate and graduate) participated in the experiment. Subjects exerted three forces (pushing, lifting, and twisting clockwise) in each experimental condition. The order of 16 treatment conditions was determined randomly. Results showed that the effects of the four factors were different according to three forces. While lifting and twisting forces were higher in 'knuckle height', the pushing force was higher in 'KH + 0.1 ${\times}$ stature' (p < 0.05). Lifting and pushing forces showed higher values in the horizontal angle $0^{\circ}$ than in $15^{\circ}$. Handle width and vertical angle showed no statistically significant main effects on three forces (p > 0.05). Results of this study could be used as basic data for the ergonomic design of handle variables of one- or two-wheel barrows.

In a study about minerals cycling in grassland agro-ecosystem, investigation on relations among two minerals, potassium(K) and magnesium(Mg), and nitrogen(N) was performed. Four kinds of diets different in K and N levels were fed to four goats with a Latin-square method and $2{\times}2$ factorial design. As the basal diet, press cake silage prepared from Italian ryegrass was used because of its uniformity and comparatively low mineral concentrations. Supplementation of K and N were made using potassium bicarbonate and urea. In the experiment, it was clearly shown that high K concentration in the forage crops is the main reason of the low utilization of Mg in ruminant animals. However, high nitrogen intake resulted in the increase of magnesium retention, urinary potassium excretion, water intake and volume of urine and in the decreases of potassium intake minus urinary potassium excretion. The results of high nitrogen intake seemed to be produced in the following order;increase of urine, increase of water intake, increase of urinary potassium excretion, and decrease of intake minus urinary potassium excretion. The amount of potassium intake minus urinary potassium excretion had significantly close relationships with magnesium utilization and serum magnesium concentration. As a conclusion, higher nitrogen intake by ruminants seemed to be preferable for magnesium utilization through increased water intake and urinary potassium excretion, if the sufficient drinking water could be supplied to ruminants.
