  • The purpose of this study was to investigate the maternal parenting stress and related variables through early childhood in rural areas (Iksan and Kimpo). The subject were 134 mothers who have less than 5-year old children. The statistics used for this data were freguency, percentile, t-test, ANOVA, and multiple regression analysis. The main results obtained from this study were as follows. The degree of maternal parenting stress differed according to level of mother's education, sex of the child, physical and mental health of the mother, child rearing attitudes, mother's level of self-differentiation, marital satisfaction, and father's parenting support. Results of the regression analysis that the etiologic model of this study were that father's parenting support is the most effective variables in rural areas.

  • The purpose of this study was to identify important factors influencing fragrance sensibility responses as well as to explore fragrance sensibility factors affecting attitude toward and buying intention of perfume products. For data collection, smelling experiments were conducted with seven groups of 34 female consumers who are aged from the 20's to 40's. Data were analyzed by ANOVA, t-test, factor analysis, and linear regression analysis. In results, five factors (pleasant, romantic, stimulating, modem, familiar factors) were generated from the factor analysis of 24 fragrance sensibility factors. These fragrance sensibility factors significantly affected both attitude toward and buying intention of perfume products. Pleasant, romantic and familiar factors were considered as important factors affecting attitude and buying intention while the stimulating factor affected only buying intention. Fragrance sensibility factors influencing attitude and buying intention of perfume products differed in terms of age and purchase level of consumers.

  • The purpose of this study was to analyze the effects of after aquatic exercise on gait in the Falls Experienced elderly. There were one group : Fall Experienced Elderly Women(n=8). They were tested on their gait (Elapse time of each phase, Stance time of limb, Stride length, Velocity of segment). we took video and analyzed their movement using Ariel Performance Analysis System and compared gait parameters. For data analysis, mean and standard deviation scores were calculated, and correspondence sample t-test and pearson's correlation analysis were used. First, after exercise is short than before exercise on Elapse time of each phase, fall-experience subjects showed meaningful total time. Second, after exercise is short than before exercise on Stance time of limb and Stride length, fall-experience subjects showed meaningful Stride length. Third, after exercise is fast than before exercise on Velocity of segment.

  • An equivalent drawbead model(EDM) for sheet metal forming analysis, which replaces complex drawbead geometries with drawbead forces in modeling the stamping dies with finite elements, is experimentally verified and applied to the numerical simulation of auto-panel stamping process. The drawbead restraining and opening forces of elliptical drawbead, circular drawbead, square drawbead, and step drawbead are obtained by performing the drawbead pulling test and compared with those of EDM and commercial code models(CCM). Better agreement with experimental measurements is found in EDM than CCM. Furthermore, the excellence of EDM is demonstrated in its application to the auto-body stamping analysis.

  • Fractal dimension is the method to measure the roughness and the irregularity of something that cannot be defined obviously by Euclidean dimension. And the analysis method of this dimension don't need perfect, accurate boundary and color like analysis lot diameter, perimeter, aspect or reflectivity of wear particles or surface. If we arranged the morphological characteristic of various wear particle by using the characteristic of fractal dimension, it might be very efficient to the diagnosis of driving condition. In order to describe morphology of various wear particle, the wear test was carried out under friction experimental conditions. And fractal descriptors was applied to boundary and surface of wear particle with image processing system. These descriptors to analyze shape and surface wear particle are boundary fractal dimension and surface fractal dimension.

  • The purpose of this study was to examine factors affecting compulsive buying behavior purchasing behavior. Four hundred female college students who have purchased fashion products via Internet shopping or TV home shopping were surveyed. For data analysis, descriptive statistics, factor analysis, t-test, and multiple regression analysis were used. As the results, 16.3% of respondents were revealed as compulsive buyers. For materialism instrument, four factors of materialism were found and labeled as 'material'. 'consumption', 'happiness', and 'economic value' factors. Also, two factors of entertainment pursuit were also identified as 'change' and 'adventure' pursuit. There were statistically significant differences between compulsive buyers and non-compulsive buyers in terms of materialism, success, and change pursuit, self-esteem, compensation, impulsive purchasing, and binge eating. Compulsive consumption scores were correlated to higher materialism, compensatory, impulsive purchasing, binge eating, shifting, entertainment pursuit, and lower self-esteem. Also, results of multiple regression revealed that compensatory, binge eating, and happiness pursuit were significantly to related to compulsive buying.

  • This study examined the factors(intrinsic cues, extrinsic cues, private brands familarity, store loyalty) influencing clothing PB preference of large-scale discount stores, and investigated the differences according to the consumer's decision types. Questionaries were collected from 316 female customers in front of the discount stores and the data were analyzed by SPSS 12.0 using T-test, correlation, regression analysis and cluster analysis. The results were as follows. First of all, According to the correlation and regression analysis, the private brand preference were influenced by store loyalty and PB familiarity. Secondly, Differences are found according to the consumer's decision types. That is the price-conscions consumers regard store loyalty, PB familiarity, extrinsic cues, and PB preference more importantly than the value-conscious consumers.

  • This study applied the Stochastic Frontier Analysis to estimate which independent variable affects to efficiency of aquaculture household. This study used wage and facility scale as input variables, sales volume as an output variable to estimate efficiency. Also, the study used region, species, water quality to estimate technical inefficiency factors of the model. The data used for this study were obtained by the operating costs survey using 1:1 interview method. The study selected translog production model with technical inefficiency term estimated as half-normal distribution. In addition, the study used pearson and spearman correlation coefficient among efficiency estimating models. Also, the study analysed differences among estimated efficiencies through t-test, and showed us 0.1793 in species, 0.4677 between Geojae and Masan.
