The importance of constraints has been one of major issues in recreation for prediction of choice behavior; however, traditional conjoint choice model did not consider the effects of these variables or fail to integrate them into choice model adequately. The purposes of this research are (a) to estimate the effects of constraints in theme park choice behavior by the constraints-induced conjoint choice model, and (b) to test additional explanatory power of the additional constraints in this suggested model against the more parsimonious traditional model. A leading polling agency was employed to select respondents. Both alternative generating and choice set generating fractional factorial design were conducted to meet the necessary and sufficient conditions for calibration of the constraints-induced conjoint choice model. Th alternative-specific model was calibrated. The log-likelihood ratio test revealed that suggested model was accepted in the favor of the traditional model, and the goodness-of-fit($\rho$$^2$) of suggested and traditional model was 0.48427 and 0.47950, respectively. There was no difference between traditional and suggested model in estimates of attribute levels of car and shuttle bus because alternatives were created to estimate the effects of constraints independently from mode related variables. Most parameters values of constraints had the expected sign and magnitude: the results reflected the characteristics of the theme parks, such as abundance of natural attractions and poor accessibility in Everland, location of major fun rides indoor in Lotte World, city park like characteristics of Dream Land, and traffic jams in Seoul. Instead of the multinomial logit model, the nested logit model is recommended for future researches because this model more reasonably reflects the real decision-making process in park choice. Development of new methodology too integrate this hierarchical decision-making into choice model is anticipated.

Tropical tasar silkworm, Antheraea mylitta is a commercial forest silkworm in India that produces tasar silk, but never experimented in Uttarakhand, a Himalayan state of India. A. mylitta express divergent phenotypic characters under different ecological conditions; so, we studied the effect of seven forest tree species in two rearing seasons on variability in silk gland weight of Daba (bivoltine) ecorace of A. mylitta at Forest Research Institute in Dehra Dun, Uttarakhand during 2012 and 2013. We used two-way completely randomized block factorial design and Post HOC Tukey's HSD test to analyse the collected data and there after carried out multiple regression analysis. Results indicated that silk gland weight differed significantly between rearing seasons (DF=1, F=2333.98, p <0.05), host plants (DF 6, F= 1516.25, p <0.05) and their interactions (DF=6, F=7.10, p <0.05). Higher silk gland weight was found in second rearing season than the first on all the host tree species. Terminalia alata fed A. mylitta larvae showed the highest silk gland weight of 8.03 and 9.47 g in first and second rearing seasons, followed by T. tomentosa (7.19 & 9.01g), T. arjuna (6.8 & 8.08 g) and L. speciosa (6.57 & 7.83 g) fed larvae, respectively. Post HOC Tukey's HSD test indicated that silk gland weight of L. speciosa and T. arjuna fed larvae in both the rearing seasons did not differ significantly. E.I. analysis also confirmed that T. alata, T. tomentosa, T. arjuna and L. speciosa are better in their order of merit than T. bellirica , T. chebula and L. tomentosa. Multiple regression analysis indicates that larval weight gain is a strong predictor (β=1.002, t=346.777, p = <0.05) for the silk gland weight of A. mylitta ; however, larval duration had significant negative regression weight (β=-0.270, t=-8.436, p = <0.05) on mean weight of silk gland.

This study aims to identify the factorial constructs of the relational benefits perceived by consumers of outdoor wear brands and their impacts on the consumers' trust in and satisfaction with outdoor wear brands. An online survey was conducted with females and males between the ages of 20 and 50 who have experienced buying outdoor wear brands. A total of 420 responses were analyzed by factor analysis, a reliability test, and multiple regression analysis. The results of this study were as follows: first, the results of factor analysis and the reliability test on the relational benefits perceived by outdoor wear brand purchasers clearly showed conceptual constructs that included informational benefits, social benefits, and psychological benefits. The sub-dimension of perceived relational benefits had significant effects on brand trust and satisfaction. Specifically, respondents revealed that they had higher brand trust if they felt psychologically comfortable, were offered useful information by outdoor wear brands, and had a favorable relationship with salespeople when they bought outdoor wear merchandise. Secondly, influences of perceived relational benefits on brand trust and satisfaction were not shown to differ depending on the congruity between outdoor wear brands and the purchaser's self-image. On the other hand, factors of perceived relational benefits revealed to differently have effects on brand trust and satisfaction depending on respondents' gender and age. Practical implications to understand outdoor wear target customers' relational benefits, self-image congruity and demographic characteristics and to enhance trust and satisfaction with outdoor wear brands are proposed.

The main purpose of this study, based on implicit personality theory and attribution theory, was to examine whether there exist the physical attractiveness stereotype, "what is beautiful is good," in the present Korea, and if exist, what is the content of it. The index of the physical attractiveness of this study was the facial attractiveness judged by 30 female university students. The appropriateness of clothing was manipulated by 4 types of clothing perceived appropriate for two assumed situations by female university students. Three female faces having high, medium, and low attractiveness were simulated with the same body dressed four types of clothing using CAD system, and a total of 12 stimulus persons were created. A total of 524 male and female(262 of male, 262 of female) university students from 3 universities in Kwangju, Korea were participated as subjects in this study. The design for the experiment was a 3$\times$4$\times$2 randomaized factorial, with three levels of facial attractiveness (high, medium, low), and four types attire(formal-masculine, formal-feminine, casual-masculine, casual-feminine), two kinds of context (job interview, dating) in which perceptions were occurred. The data were analysed using factor analysis, MANOVA, t-test and Duncan test. The results were as follows: 1. The facial attractiveness exerted significant positive effects on the evaluation of sociability, adjustment, and potency of her in both of two assumed situations (p<.001, respectively). 2. The appropriateness of stimulus person′s clothing had significant positive erect on the evaluation of sociability of stimulus person in dating context(p<.001). 3. The gender of subjects did not influenced the trait evaluations in both of two assumed situations.

The goal of this study is to examine the sociality and school adjustment of elementary school lower-class students. The following research hypotheses were set up and addressed: Hypothesis 1: There would be significant differences in sociality of the elementary school lower-class students according to activity - making friends group counseling Program. Hypothesis 2: There would be significant differences in school adjustment of the elementary school lower-class students according to activity - making friends group counseling Program. The subjects for the study were 20 first grade students attending N elementary school in Daejeon area. The students were assigned to the two groups-experimental group(N=10) and controlled group(N=10). The experimental group received 10 sessions of the activity - making Friends group counseling program for 40 minutes by 2 times every week, and the controlled group didn't do anything. To verify the hypotheses, two tests(sociality and school adjustment tests) were administered for the pretest and post-test. Means and standard deviations obtained from these tests were analyzed with factorial covariance test using SPSSWIN(10.0). The results were as follows: Hypothesis 1 was confirmed. The scores of experimental group were significantly higher than those of controlled group in sociability, cooperation and independence, but not in observance. Hypothesis 2 was confirmed. The scores of experimental group were significantly higher than those of controlled group in teacher-student relationship, student-student relationship and classes, but not in the keeping rules. The conclusion of the result is that the program have a good effect on the elementary school lower-class students' sociality and school adjustment. Above all, along with long-term adaptability of the research, continuous studies are required.

This study was designed to find out the effects of country-of-origin and price on the perceived quality, perceived value and purchase willingness of t-shirt products. This study will allow marketers to find the target consumers and to choose both the suitable country -of -origin and the reasonable selling price. This study was based on theoretical and empirical methods. For the empirical methodology, 3${\times}$3 between subjects factorial design with country-of-origin (U.S.A. vs. Korea vs. China) and price(high price vs. middle price vs. low price) was used. The nine types surveys by country-of-origin and price were transmitted to 960 undergraduate and graduate school students in Seoul. A total of 912 questionnaires were used in the final statistical analyses using factor analysis, MANOVA, Duncan test, and Tukey test. The results of this study were as follows: First, in the case of the perceived quality, participants evaluated t-shirt products better when the origin is U.S.A. followed by Korea and China in the order. Second, price affected the perceived value and purchase willingness. In the perceived value and purchase willingness, low priced t-shirt products were evaluated higher than the middle and high priced ones. Third, in the perceived quality, high priced Korean t-shirt products were evaluated lower than high and middle priced American t-shin products. In the perceived value, low priced Chinese t-shirt products were evaluated lower than middle priced Korean t-shirt products. In the purchase willingness, low priced American and low priced Korean t-shirt products and middle priced Korean t-shirt products were evaluated higher than all priced Chinese t-shirt products.

This study compares the expected values of appearance management for the suit buying behavior of men in two age groups: (20s-30s and 40s-50s) to investigate the effect of male consumers' expected values in regards to appearance management on the purchase behavior of men's suits between two generations. A survey was carried out with male consumers between the ages of 20 and 50; a total of 135 responses were analyzed by descriptive analysis, factor analysis, a reliability test, an independent samples t-test, MANOVA, ANOVA, and regression analysis. The results of this study were as follows: 1) From a result of the factor analysis on male consumers' expected value of appearance management and the information sources and purchase evaluative criteria for buying men's suits, each of three variance assessments clearly showed factorial structures. 2) There were significant differences between those in their 20s-30s and those in their 40s-50s in terms of male consumers' expected values of appearance management, their information sources, and their purchase evaluative criteria when buying men's suits. 3) As a result of looking at the differences in the effects of expected values of appearance management on men's suit buying behavior according to age (generation), the younger generation in this study showed that men's suit purchasing tendency was affected by the managing appearance factor for internal reasons such as enjoyment and self-satisfaction. On the other hand, the assessment of the older generation revealed that appearance management for external reasons such as showing social power, good human relationships, and conformity influenced their suit purchase behaviors.

The objectives of this study were to analyze the effect of dress(Korean traditional dress and suit) of elderly Women and situation on impression formation. The experimental design was $10\times{2}\times{2(dress}\times{perceiver's age}\times{situation)}$ factorial design by 3 independent variables. The stimuli of color photographs of female in her 60's model and the semantic differential scale were used. Six variables of impression formation were used: preference: elegance: potency: activity: feminine: and modernity. Samples were 400 women 200 were in their twenties and 200 in their forties and fifties. The data were analyzed by $\alpha$-reliability t-test ANOVA and duncan's multiple range test. The Korean traditional dress with the combination of Korean traditional color(light blue upper dress with dark red purple collar and string.dark blue skit) had the most positive effect on impression of elegance. Pink traditional dress and light blue traditional dress had a negative effect on impression of potency activity and modernity. Red purple suit had a positive effect on potency and modernity. The interaction between dress perceiver's age and stituation was significant for the impression of activity. Women in their 40's and 50's perceived the activity of red purple suit positively in the situation of alumnae meeting more than in the wedding ceremony. The perceived age of the stimulus person was different according to dresses. Traditional dresses was perceived older than suits were. Women in their 40's and 50's evaluated preferences of the dresses positively more than 20's did. This means that 40's and 50's feel similarity with the stimulus person more than 20's as the age of model was in their 60's The result supports the theory that similarity is basic factor in interpersonal attraction.
