  • The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

  • Silicon carbide (SiC) was etched in a $NF_3/CH_4$ inductively coupled plasma. The etch process was modeled by using a neural network called generalized regression neural network (GRNN). For modeling, the process was characterized by a $2^4$ full factorial experiment with one center point. To test model appropriateness, additional test data of 16 experiments were conducted. Particularly, the GRNN predictive capability was drastically improved by a genetic algorithm (GA). This was demonstrated by an improvement of more than 80% compared to a conventionally obtained model. Predicted model behaviors were highly consistent with actual measurements. From the optimized model, several plots were generated to examine etch rate variation under various plasma conditions. Unlike the typical behavior, the etch rate variation was quite different depending on the bias power Under lower bias powers, the source power effect was strongly dependent on induced dc bias. The etch rate was strongly correated to the do bias induced by the gas ratio. Particularly, the etch rate variation with the bias power at different gas ratio seemed to be limited by the etchant supply.

  • This research aims to examine the model of investor herding behavior in making investment decisions in the Indonesian capital market, which is influenced by social and information impacting on the value of the Book Value Per Share (BVPS). The latest stock market conditions show that most investors make the same error pattern in making investment decisions that result in losses. The experiment involves two independent variables, namely, information about BVPS and social influence. This study used a 2×2 factorial design laboratory experimental method. Data collection was carried out through treatment of a sample of 100 individual investors listed on the Indonesia Stock Exchange. Univariate Two-Way Analysis of Variance (ANOVA) statistical tool was used to test the independent variable on the dependent variable. Research results showed that the social influence originating from expert investors is more influential than the Book Value Per Share (BVPS) information on the behavior of herding investors in making investment decisions. These findings suggest that investors know their psychological factors, thereby increasing self-control and investment analysis skills. Further research can use psychological bias and other indicators of accounting relevant information such as Earning Per Share (EPS) to test herding behavior in investment decision making in the capital market.

  • This study aims to investigate the impacts on adolescents of the application of the education program for ethical consumption related to clothing in terms of their clothing-related ethical consumption consciousness, and in terms of their general ethical consumption knowledge and behaviors. Additionally, the effects of clothing-related ethical consumption consciousness and general ethical consumption knowledge on general ethical consumption behavior were examined. The program for education in ethical consumption related to clothing for adolescents was developed and applied, two surveys for the pre-post test design were conducted with high school female and male students, and a total of 158 responses were analyzed. The results of this study were as follows. 1) The results of the factor analysis and the reliability test on ethical consumption consciousness for high school students clearly showed factorial structures including Pro-environmentalism, Animal welfare, Social responsibility, and Recycling. 2) Analysis of the differences in the means of ethical consumption consciousness, knowledge, and behaviors of respondents between pre-test and post-test revealed that posttest means of all research variables after application of the education program were higher than pre-test means. 3) The ethical consumption knowledge had important medicating roles in the relationship between ethical consumption consciousness with regard to clothing and general ethical consumption behaviors. Overall, the study provides empirical evidence to support the notion that there is a need for applying an ethical consumption education program to lead adolescents to consume ethically.

  • As an experimental reference population, crosses between Korean native pig and Landraces were established and information on growth traits was recorded. Animals were genotyped for 24 microsatellite markers covering chromosomes 2, 6, and 7 for partial-genome scan to identify chromosomal regions that have effects on growth traits. quantitative trait loci (QTL) effects were estimated using interval mapping by the regression method under the line cross models with a test for imprinting effects. For test of presence of QTL, chromosome-wide and single position significance thresholds were estimated by permutation test and normal significance threshold for the imprinting test were derived. For tests against the Mendelian model, additive and dominance coefficients were permuted within individuals. Thresholds (5% chromosome-wide) against the no-QTL model for the analyzed traits ranged from 4.57 to 4.99 for the Mendelian model and from 4.14 to 4.67 for the imprinting model, respectively. Partial-genome scan revealed significant evidence for 4 QTL affecting growth traits, and 2 out of the 4 QTLs were imprinted. This study demonstrated that testing for imprinting should become a standard procedure to unravel the genetic control of multi-factorial traits. The models and tests developed in this study allowed the detection and evaluation of imprinted QTL.

  • A factorial ($4{\times}2{\times}2$) experimental design was employed to determine apparent digestibilities of dry matter (DM), protein, lipid, energy and nitrogen-free extract (NFE) of the test diets containing either ${\alpha}$-potato starch (A-PS), ${\beta}$-potato starch (B-PS), ${\beta}$-corn starch (B-CS) or dextrin (DEX) as dietary carbohydrate energy for juvenile (average weight 30 g) and grower (average weight 300 g) rockfish reared at 13$^{\circ}C$ and 20$^{\circ}C$. Chromic oxide was used as an inert marker. Feces were collected by fecal collectors attached to rearing tanks from triplicate groups of juvenile and grower rockfish. Digestibilities of DM, energy and NFE of the test diets were significantly affected by dietary carbohydrate and water temperature (p<0.01), but not by fish size. DM digestibility of the fish fed the A-PS diet was significantly higher than that of fish fed other treatments, except for the DEX diet at 20$^{\circ}C$. DM digestibility of rockfish fed the B-CS diet was significantly lower than that of other diets. A similar pattern was observed in apparent digestibility of energy. NFE digestibility of fish fed the test diets was significantly affected by carbohydrate and significantly correlated to DM (r = 0.97, p<0.01) and energy (r = 0.99, p<0.01) digestibilities, regardless of water temperature and fish size. NFE digestibility of the fish fed the ${\beta}$-starch diets was relatively lower compared to that of the ${\alpha}$-starch diets, and ranged from 35 to 43% and 20 to 27% for B-PS and B-CS, respectively. The present findings indicate that carbohydrate and water temperature significantly affected digestibilities of dry matter, energy and nitrogen-free extract of rockfish. Among dietary carbohydrates, ${\alpha}$-potato starch could be effectively used as dietary carbohydrate energy for rockfish at 13$^{\circ}C$ and 20$^{\circ}C$.

  • The purpose of this study is to test the psychometric properties of the Korean version of the Health-Related Hardiness Scale(HRHS) in a sample of Korean nursing students. The korean version of HRHS was administered to 234 nursing students including 135 college students and 99 university students. The Korean version of HRHS was measured on a 6 Likert scale, assessing three factors of HRHS : control, commitment, and challenge. Internal consistency was used to test the instrument's reliability. The internal consistency of the scale was measured using a coefficient alpha. The coefficient alpha was .69(control), .49(commitment). and .69(challenge), Item analysis and confirmatory factor analysis (CFA) were used to test the instrument's construct validity. The item analysis identified that there were 13 items. which were lower than the .25 item-total correlation. CFA revealed that the scale's fadoral validity was not proper by showing unfit indices(RMSEA .07. stand, RMR .09. GFI .71). According to the findings of this study, the reliability and construct validity of the Korean version of HRHS is not satisfactory in the sample of nursing students. As a result. the researcher modified the scale through item analysis and repetitive CFA process, and proposed the revised 25-item Korean version of HRHS for nursing students. The revised scale's reliability(control .74, commitment .73. challenge .77) and factorial validity were within acceptable levels. The item analysis identified that there was no item, which is lower than the .25 item-total correlation. CFA revealed that the scale's factoral validity was proper by showing fit indices(RMSEA .08 stand. RMR .08. GFI .80).

  • The purpose of this study is to identify conceptual constructs of well-being consciousness and appearance management behaviors, and to examine the effects of these two variables on attitudes toward Korean herbal cosmetics for Korean and Japanese consumers. A survey was carried out among female consumers between the ages of 20 and 50, and a total of 500 responses were analyzed by descriptive analysis, reliability test, t-test, and confirmatory factor analysis, structural equation modeling and multi group analysis. The results of this study were as follows: 1) The result of CFA and the reliability test on well-being consciousness and appearance management of Korean and Japanese respondents clearly showed factorial structures on each of the variant assessments. 2) In regards to the well-being consciousness, Korean and Japanese respondents highly tended to perceive well-being as a benefit to the physical health and an eco-friendly lifestyle respectively. In the area of appearance management, Korean and Japanese respondents had similar patterns that showed high scores of skin care and weight control. Both Korean and Japanese consumers showed favorable attitudes toward Korean herbal cosmetic products. 3) The consumers' well-being consciousness revealed to have positive influences on appearance management behavior. Both well-being consciousness and appearance management positively influenced attitudes toward Korean herbal cosmetics. 4) As a result of MGA, the well-being consciousness had more positive impacts on Korean respondents' attitudes toward Korean herbal cosmetics than the appearance management variable when compared to the Japanese respondents. On the other hand, appearance management had more positive impacts on Japanese respondents' attitudes to-ward Korean herbal cosmetics than well-being consciousness when compared to the Korean respondents. These results suggest that differentiated marketing strategies for Korean herbal cosmetics are crucial when targeting Korean and Japanese consumers.
