With the appearance of many new types of fashion stores in Korea, competitions among fashion store types art fiercer than ever before. As consumers alternatives in fashion store selection increase, they select different store types to purchase different product types. Therefore, the probability of patronage mix behavior according to product type increases. Understanding consumers patronage mix behavior, finding out the determinant attributes of fashion stores for each product type, and analyzing competitive structures among fashion stores are important to retailers and marketers for building a successful merchandising and marketing strategies. An empirical study was conducted to analyze the competitive structure among the store types by consumers' patronage mix behavior. A questionnaire was developed and data were collected from 464 adult women living in Seoul area in Korea. Factor analysis, paired t-test, ANOVL Duncan test, and discriminant analysis were employed to analyze the data. Data regarding patronage mix behavior by product type proved that certain store types had ‘natural dominance’ in a particular product type as Hirschman(l978) pointed out. Also, a new analytic method of the competitive structures among fashion store types was suggested in the study, by which a specific store type retailer can analyze his/her own customers' patronage mix behavior by product type. The analysis will enable retailers to distinguish which of their competitors are substitutive, selling same product types, and which are complementary, selling different product types. Retailers have to concentrate on the strategies for the substitutive competitors rather than complementary competitors because their marketing abilities and resources are limited.

This research proposes a pattern design method for 24 pleated skirts in order to develop an automatic draft program for pleated skirts that will enhance fit and enable mass production. The research method and results are outlined as follow. 1. Three-dimensional body measurements were conducted on 30 randomly selected women in their 20s. By using 34 body measurement items and 6 types of calculations among the items, the items required in the designing of an original pleated skirt were extracted. They were then interpreted through correlation analysis, variance analysis, a t-test, linear regression analysis and multiple regression analysis. 2. An extra amount was added to the waist measurement and external capsule measurement according to the number of times the pleats coincided and the thickness of the fabric by the degree of polymerization of the horizontal cross section (the test of this research: 0.518mm). The extra amount of waist measurement was 3.6cm while the hip measurement was 4.3cm larger than the hip measurement combined with the external capsule measurement and the extra amount. 3. Based on the ${\pm}$standard deviation/2 as the average of the difference between the external capsule measurement and waist measurement, the subjects were classified into 3 somatotypes. Somatotype 1 presented an average total length of waist darts of 23.6cm while that of somatotype 2 was 26.2cm and that of somatotype 3 was 30.2cm. It has been confirmed that there is a significant difference among somatotypes in the total length of waist darts from the front center to the front side and the total length of waist darts from the side to the back center in terms of the average amount of waist darts for every 12 parts on the WL.

The purpose of this study was to examine the relation of elementary school children's stress and coping behavior in urban and rural areas. The subject included 286 children selected from 4 elementary schools in urban and rural areas. The instruments included the children's stress index and coping behavior questionnaire of the elementary school children. The statistics used from this data were t-test, one-way ANOVA(Duncan test), correlation analysis and multiple regression analysis. This study showed significant differences between urban and rural children's stress in school attainment domain, teacher-school domain, home environment domain and surroundings domain. And urban and rural children was different in active, passive/avoidant and aggressive coping behavior. The stress of urban's children was influenced significantly by the grade and school attainment variales, and the rural children's stress was influenced significantly by the gender variable. The coping behavior of urban's children was influenced by the gender, grade and school attainment variables, and also the rural children's coping behavior was influenced by the above variables. Correlation analysis indicated that children's stress and aggressive coping behavior were relative positive high correlation in urban areas, and children's stress and passive/avoidant coping behavior were positive high correlation in rural areas. It was also found that school attainment, aggressive coping behavior and passive/avoidant coping behavior were significant predictors of urban children's stress, and gender, passive/avoidant coping behavior and aggressive coping behavior were significant predictors of rural children's stress.

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.

This study was carried out to evaluate Korean eating behavior which is highly correlated with their nutritional status, and to analyze the effect of various factors on eating behavior. The above information was used to develop a nutritional status for Korea. The 2000 Korean people were selected with the stratified random sampling method. This study used a questionaire as instrument tool. The questionaire consists of :1) socio-demographic characteristics of the subjects; 2) the valuation of food and nutrition; 3) the concern of food and nutrition; 4) psychological health condition; 5) physical health condition; 6) nutrient consumption status and 7) analysis of eating behavior. Data were analyzed by using a SPSS PC Package. Significant differences and correlation among variables were determined by the t-test, $x^2-test$, ANOVA, pearson's correlation coefficient and Multiple regression analysis. The results of this study can be summarized as follow, All nutrient intakes were significantly correlated with eating behavior score(p<0.001). Factors such as socio-economic status, valuation and concern on food and nutrition, and psychological health condition had significant relationship with eating behavior. But the physical health condition had no significant effect on it. Multiple regression analysis showed that valuation of food and nutrition made the greatest contribution(35.6% explained) and concern made the second greatest contribution(10.5% explained). The third was education level(9.8% explained), and the forth psychological health condition(1.8% explained).

Objectives The purpose of this study is to evaluate the effects of attachment security, social support and health-related burden in the prediction of psychological distress and the mediation effects of social support and health-related burden in relationship between attachment security and psychological distress. Methods Finally, 161 patients were included for the analysis. Chi-square test and independent samples t-test were used for comparing differences between depressive/anxious group and non-depressive/non-anxious group. For evaluating the relationship among attachment security, social support, psychological distress and health-related burden, structural equation modeling analysis were performed. Results 40.7% and 32.0% of the patients have significant depressive symptoms and anxiety symptoms, respectively. In the analysis for testing the differences between groups who have psychological distress and who have not, there were no significant differences of sociodemographic factors and medical characteristics between groups, except for association between depressive symptoms and type of surgery (p = 0.01). Contrary to sociodemographic and medical characteristics, there were significant differences of health-related burden and two coping resources (attachment security and social support) between groups (all p < 0.01), except for the support from medical team in between anxious group and non-anxious group (p = 0.20). In the structural equation model analysis (Model fit : chi-square/df ratio = 0.8, root mean square error of approximation = 0.000, comparative fit index = 1.000, non-normed fit index =0.991), attachment security and social support emerged as an important predictor of psychopathology. Conclusions Attachment security and social support are important factors affecting the psychological distress. We suggest that individual attachment style and the social support state must be considered to approach the newly diagnosed breast cancer patients with psychological distress.

The purpose of this study was to examine the relationship between parenting stress, social support and the social development of preschool children in rural areas. The subject included 114 preschool children, along with their mothers, selected from kindergartens and day care centers in rural areas. The instruments included the parenting stress index, social support inventory and the social maturity scale. The statistics used from this data were t-test, one-way ANOYA(Scheffe test), correlation analysis and multiple regression analysis. This study showed that maternal parenting stress was influenced significantly by the related variables; gender of child, birth order of child, age of mother, educational attainment of mother, family income, religion, family type. And also, social support was influenced significantly by the above variables. The child's social development was influenced significantly by the variables that related child and the family. Correlation analysis indicated that parenting stress and social development of the child were relatively negative high correlation coefficients. And social support and social development of the child were relatively positive high correlation coefficients. The important factors on predicting social development of the child were found to be birth order of child, age of mother, educational attainment of mother, family income, religion, family type, daily stress, stress of difficult child, stress of parent-child dysfunctional interaction, educational distress, husband support, and other support. Especially stress of difficult child and husband support were important variables that predicted the social development of the preschool children.

The startup characteristic of liquid propellant rocket engine should be focused on the stable ignition of combustion chamber and gas generator. Also, to lessen the propellants consumption during this period which doesn't contribute to the flight thrust, the engine has to be transferred to the nominal mode quickly. Because of the risk of test, it is impossible to develop all the startup cyclogram or the specifications of engine by test, so the precedent numerical approach is quite necessary. In this study we developed a mathematical model for the startup phenomena in a liquid rocket engine driven by gas generator-turbopump system based on the commercial 1-D flow system analysis program, Flowmaster. Using this program we proposed a methodology to obtain the specifications of turbine starter and the opening time of shutoff valves for the stable startup of the engine. To verify this methodology we qualitatively compared the analysis results to the typical startup curve of the published engine, then found it is quite well matched.
