The primary purpose of this paper is to estimate the wealth effect. We establish a linear relationships between household consumption, labor income, and stock price index. Each variable is nonstationary. And so, it contains a unit root. However, as the result of the test about cointegrating relations, the variables are cointegrated which implies the error term is stationary. The cointegrating parameter that the marginal propensity to consume out of stock price is 0.08%. The result of estimation shows the error correction is -0.62 and the significant level is also high. The error correction term indicates a rather rapid adjustment to deviations from the long run equilibrium relations.

Recently, the market has been released a lot of excellent NVH performance cars such as hybrid, electric and luxury cars. Therefore, the consumer is a tendency of many sensitive of the noise inside the vehicle than in the past. In order to match the propensity of such consumers, the automotive industry defines the standard of product related to noise generation of a single product. However, it is difficult to reduce the noise of the product to automobile part suppliers to follow these standards. In this paper, we propose a method for evaluating several necessary in order to find a way to reduce the noise.

This paper deals with friction-induced vibration of disc brake system under constant friction coefficient. A linear, lumped and distributed parameter model to represent the floating caliper disc brake system is proposed. The complex eigenvalues are used to investigate the dynamic stability and in order to verify simulations which are based on the theoretical model, the experimental modal test and the dynamometer test are performed. The comparison of experimental and theoretical results shows a good agreement and the analysis indicates that mode coupling due to friction force is responsible for disc brake squeal. And squeal type Instability is Investigated by using the parametric analysis. This indicates parameters which have influence on the propensity of brake squeal. This helped to validate the analysis model and establish confidence in the analysis results. Also they may be useful during system development or diagnostic analysis.

The purpose of this study is to focus on the fashion communicating of the East and the west. For this purpose, the study will analyze the Visions of the East in Western Dress has long expressed an intense multiculturalism. This study is realized that clothing has served to consolidate more then to segregate. While never losing the characteristics of its place of origin, clothing has shown itself a reading assimilated object portability and ephemerality promote investigation, at the very least. Eastern ideas of textile, design, construction, and utility has been realized again as a positive contribution to the culture of the West. The East offers a larger concept in alternative to the Western propensity for tailoring. In giving primacy to the textile, Eastern dress emphasizes the flat terrain of cloth, the looping and Wrapping of the garment, and the integrity of the untailored textile. There values, antithetical to postmedieval Western dress, have offered a paradigm of dressing and dressmaking to the West that has been sporadically Influential, and notably so in our time.

The purpose of this study were to classify the door to door selling consumers's according to their cosmetics lifestyles and to analyze the cosmetics a purchase behavior and satisfaction of classified groups. subject were 424 women living in chung-cheong and kyung-gi. The statistical methods to analyze the data were frequency, t-test, factor analysis. cluster analysis, and ANOVA(LSD) using SPSSWIN package. Considering that there were significant differences in the behavior of uses, purchase propensity according to cosmetics lifestyles for door to door selling, it is reasonable that the consumer market should be subdivided by their cosmetics lifestyles and the quality improvement and distinguished sales strategies should be required.

Fasciclin 1 (FAS1) is an extracellular protein whose aggregation in cornea leads to visual impairment. While a number of FAS1 mutants have been studied that exhibit enhanced/decreased aggregation propensity, no structural information has been provided so far that is associated with distinct aggregation potential. In this study, we have investigated the structural and thermodynamic characteristics of the wild-type FAS1 and its two mutants, R555Q and R555W, by using molecular dynamics simulations and three-dimensional reference interaction site model (3D-RISM) theory. We find that the hydrophobic solvent accessible surface area increases due to hydrophobic core repacking in the C-terminus caused by the mutation. We also find that the solvation free energy of the mutants increases due to the enhanced non-native H-bonding. These structural and thermodynamic changes upon mutation contribute to understand the aggregation of these mutants.

The purpose of this study is to analyze consumption expenditure patterns over family life cycle. The data used in the study is the 1994 Survey data from Annual Report on the Family Income and Expenditure Survey. The study sample included 26,980 salary and wage earners’ households living in cities. The family life cycle was classified into six stages and items of expenditure were classified into 12 categories. Frequency distribution, mean, one-way ANOVA, Scheff test, and regression analysis were used to analyze the data. The major findings of this study are as follows : First, the average consumption propensity differs among family life cycle. Second, the amount and budget share of consumption expenditure for each expenditure category differ significantly among family life cycle in all expenditure categories. Third, family life cycle is found to be a significant factor on expenditure of food and education, and also on budget share of education.

This study was designed to investigate purchasing and post-purchase behaviors of middle-aged wives in buying townwears, an well as to examine socio-demographic variables, physical variables, psychological variables, and their influences on. The data included 374 housewives in Seoul and Pusan. Statistics used for data analysis were Frequencies, Means, Standard Deviation, t-test, ANOVA, Pearson's Correlation. The major finding are as follows: 1. The level of post-purchase satisfaction marked higher than middle point. 2. Post-purchase satisfaction differed significantly in income, health-state, identity, stress perceptivity, income satisfaction, sense of comparison, and propensity to consume.

This research analyze the impact factors that affect the PI resistance of securities brokerage salespersons during Process Innovation in securities companies focusing on the broker's individual personality. After reviewing some related literatures, a survey was conducted at a domestic securities company with the derived factors from a focus group of securities salesmen with over 10 year work experience. The results show that broker's individual propensity to innovation, individual customer relationship and individual flexibility are closely related to the PI resistance. By controlling such factors for salespersons, securities companies can boost the ability to meet and control the changing situation and management innovation.
