The purpose of the present study were 1) to identify the dimensional structure of impression formed of a female figure, 2) to analyze effects of several elements of apparel design on impression formation of the figure in suit. The experimental materials developed for this study were a set of stimuli and a response scale. The stimuli consisted of 60 drawings made by identical manipulations of 3 indepndent variables in 3 clothing styles(suit, dress and pants with blouse). The independent variables were (1) five clothing colors (red, blue, yellow, white and black), (2) two lengths(short/long) of suit skirt, dress, and pants (3) two types of blouse and dress collars (shirt collar/ribbon collar). The 7-point semantic differential response scale to measure the dependent variables (formed impressions of the female figure) was composed of 37 bipolar adjectives. Further- more, two open-ended questions were used for interpretation of the reponses. The study proceeded in three independent experimental part was based on the 3 clothing styles using a 5(color)$\times$2(length)$\times$2(collar) factorial design. Subject were 200 female undergraduate students reandomly assigned to one of 20 combinations in each part of the experiment. The data were analyzed by factor analysis, 3-way ANOVA and Multiple Classification Analysis. Five factors emerged to account for the dimensional structure of impression of the female figure in specific attire. These factors included three basic dimensions of impression identified as potency, activity and evaluation, confirming the results of previous studies. Result from open-ended questionaire supported the theoretical perspective of Schneider, Hastorf and Ellsworth on the procedure of impression formation.

Purpose: Determining the spatial structure of data is important in understanding within-field variability for site-specific crop management. An understanding of the spatial structures present in the data may help illuminate interrelationships that are important in subsequent explanatory analyses, especially when site variables are correlated or are a combined response to multiple causative factors. Methods: In this study, correlation, principal component analysis, and single and nested variogram models were applied to soil electrical conductivity and chemical property data of two fields in central Missouri, USA. Results: Some variables that were highly correlated, or were strongly expressed in the same principal component, exhibited similar spatial ranges when fitted with a single variogram model. However, single variogram results were dependent on the active lag distance used, with short distances (30 m) required to fit short-range variability. Longer active lag distances only revealed long-range spatial components. Nested models generally yielded a better fit than single models for sensor-based conductivity data, where multiple scales of spatial structure were apparent. Gaussian-spherical nested models fit well to the data at both short (30 m) and long (300 m) active lag distances, generally capturing both short-range and long-range spatial components. As soil conductivity relates strongly to profile texture, we hypothesize that the short-range components may relate to the scale of erosion processes, while the long-range components are indicative of the scale of landscape morphology. Conclusion: In this study, we investigated the effect of changing active lag distance on the calculation of the range parameter. Future work investigating scale effects on other variogram parameters, including nugget and sill variances, may lead to better model selection and interpretation. Once this is achieved, separation of nested spatial components by factorial kriging may help to better define the correlations existing between spatial datasets.

This paper describes the development of Korean version of two widely used self-report measure of alexithymia-Schalling-Sifneos Personality Scale (SSPS) and Toronto Alexithymia Scale(TAS), and present the preliminary results of their reliability and validity tested to an Korean college student sample(N=206). TAS showed moderate to acceptable internal consistancy with 0.26 of mean item-total correlation and 0.754 of Cronbach's alpha coefficient, while those parameters for SSPS turned out inconsistent. However, results of test-retest reliability for both scale were excellent. Factor analysis revealed tow factors for TAS and three factors for SSPS ; the four-factor structure of TAS was quite congruent with previously known alexithymaia construct, while, again, SSPS showed intermixed factor structure. TAS scores correlated fairly well with somatization scores enough to get concurrent validity while SSPS scores did not. Overall, Korean version of TAS demonstrated well matched findings in terms of internal consistency and factorial validity with original and Spanish version of TAS. The results suggest that Korean version of TAS could be a useful and reliable tool for the measurement in Korean population.

Objective: The objective of this study was to explore the effects of maize straw treated with calcium oxide (CaO) and various moisture, on the composition and molecular structure of the fiber, and gas production by fermentation in an in vitro rumen environment. Methods: The experiment used 4×3 Factorial treatment. Maize straws were treated with 4 concentrations of CaO (0%, 3%, 5%, and 7% of dry straw weight) and 3 moisture contents (40%, 50%, and 60%). Scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray fluorescence spectroscopy were employed to measure the surface texture, secondary molecular structure of carbohydrate, and calcium (Ca) content of the maize straw, respectively. The correlation of secondary molecular structures and fiber components of maize straw were analyzed by CORR procedure of SAS 9.2. In vitro rumen fermentation was performed for 6, 12, 24, 48, and 72 h to measure gas production. Results: Overall, the moisture factor had no obvious effect on the experimental results. Neutral detergent fiber (NDF), acid detergent fiber, acid detergent lignin, hemicellulose and cellulose contents decreased (p<0.05) with increasing concentrations of CaO treatment. Surface and secondary molecular structure of maize straw were affected by various CaO and moisture treatments. NDF had positive correlation (p<0.01) with Cell-H (H, height), Cell-A (A, area), CHO-2-H. Hemicellulose had positive correlation (p<0.01) with Lignin-H, Lignin-A, Cell-H, Cell-A. Ca content of maize straw increased as the concentration of CaO was increased (p<0.01). Gas production was highest in the group treated with 7% CaO. Conclusion: CaO can adhere to the surface of the maize straw, and then improve the digestibility of the maize straw in ruminants by modifying the structure of lignocellulose and facilitating the maize straw for microbial degradation.

This study aimed to examine the Factor Structure of the teacher satisfaction scale (TSS) with distance education during the Covid-19 pandemic, as well as affirming the (Factorial Invariance) according to gender variable. It also aimed at identifying the degree of satisfaction according to some demographic variables of the sample. The study population consisted of all teachers in public education and faculty members in higher education in the Kingdom of Saudi Arabia. The (TSS) was applied to a random sample representing the study population consisting of (2399) respondents. The results of the study showed that the scale consists of five main factors, with a reliability value of (0.94). The scale also showed a high degree of construct validity through fit indices of the confirmatory factor analysis. The results have shown a gradual consistency of the measure's invariance that reaches the third level (Scalar-invariance) of the Measurement Invariance across the gender variable. The results also showed that the average response of the study sample on the scale reached (3.74) with a degree of satisfaction, as there are no statistically significant differences between the averages of the study sample responses with respect to the gender variable. While there were statistically significant differences in the averages with respect to the variable of the educational level in favor of the middle school and statistically significant differences in the averages attributed to the years of experience variable in favor of those whose experience is less than (5) years.
