In this study the distribution patterns of the metallic components were analyzed both before and after the Asian Dust (AD) events at 2001 by comparing the chemical composition of metallic components in terms of various statistical methods. According to the AD/NAD concentration ratio of metallic components, the main components of crustal soils were exhibiting the values above 1.0; but opposite results were seen dominantly for hazardous metallic components. Examination of fine-to-coarse (F/C) ratios of metallic components showed higher values for major anthropogenic components including Pb (5.83). Ni (2.61), etc. Comparison of our measurement data with those obtained within and across the Korean peninsula indicated that the metallic distribution patterns of the study area can be distinguished from previous studies. The results of our analysis, when investigated in relation with air mass movement patterns. indicated evidence of the direct influence of AD events and anthropogenic processes.

This study examined the influence of mothers' reading and scaffolding behaviors on children's emotional experiences and memory recall during picture book reading. Sixty children, aged 6 and their mothers participated in this study. Each child-mother dyad was observed in a lab setting which was designed to evaluate child-mother interactions during a picture book reading. The data were analyzed using correlation and multiple regression techniques. Our results indicated that mothers' task-oriented reading behavior affected the children's lack of positive emotions, whereas mothers' fun-oriented reading behavior was associated with the children's positive emotions. The task-oriented reading behavior also accounted for children's poor memory performance in relation to the book. These results were discussed in terms of the relationship between emotion and cognition through book reading experiences.

Theoretical models to study the vibro-acoustic performance of a sandwich panel are proposed. The wave propagation characteristics are analyzed, and dispersion relation is derived. The vibration Is analyzed using the Mindlin plate theory. The vibration of the compliantly supported Mindlin plate is investigated using the Rayleigh-Ritz method. The Timoshenko beam functions are used as trial functions. The model is applied to numerically investigate the influence of the plate mechanical properties. The vibro-acoustic properties are mostly determined by bending deformation at low frequencies. At higher frequencies, the shear deformation has a strong influence. The proposed numerical model is used to estimate the optimal panel properties that result in minimum sound radiation. With increasing dynamic stiffnesses the vibration response decreases but the radiating wavenumber components increase.

The purpose of this study was to show occlusion on the simple hinge articulator optionally mounted. Modelling of upper-lower jaw and simple hinge articulator were developed. This modelling of upper-lower jaw inserting wax bite was mounted imaginary on the modelling of simple hinge articulator by use of the computer simulation. From changes of THA(transverse horizontal axis)-incisor distance, Balkwill angle and THA deviation, eight types were mounted respectively. After removal of wax bite, upper-lower jaw position changing were compared with centric jaw relation. The results were as follows: 1. The change of THA-incisor distance had influence on mostly a vertical shift of upper jaw. 2. The change of Balkwill angle had influence on mostly a horizontal shift of upper jaw. 3. Inferior type in the THA deviations was the least shift of upper jaw. The above results suggest that the simple hinge articulator optionally mounted effect a shift of upper jaw.

This study attempts to apply its result to decision whether housewives are in the labor market or not by investigating the level of reservation wage of them and the influencing factors on it. The purpose of this study is to analyse the effects by identifying , on the basis of theoretical models, the factors that influence reservation wage, and to predict future state of female employment. 1) The level of reservation wage of housewives showed significant differences by husband's income, household asset, housewife's education level, housewife's age, number of children division of husband in household labor, and by three marketization of housework. 2) The variables which affected reservation wage of housewife independently had influence on it in the following order: Husband's income, education level, age affect positively reservation wage of housewife, and a negative relation has been found between division of husband, level of commodity substitution and reservation wage of housewife. 3) Husband's income, housewife's education level, housewife's age, division of husband in household labor, level of commodity substitution give direct effects on reservation wage of housewife. Education level, age, number of children and family type influenced reservation wage of housewife through level of commodity substitution indirectly.

In this study, to investigate the influence on the seam puckering by the mechanical properties of textiles, it was measured from 4 polyester/cotton samples. We reached the following conclusion in influences of the seam puckering by the thread, iron and laundry. Seam puckering is occurred several times by repeating the laundry. according to iron method, the seam puckering is stronger in order of T/C1> T/C2> T/C3> T/C4 by the samples and order of 40's/2> 60's/3> 50's/2> 60's/2 by the threads, the relation between sample's mechanical properties and seam strength and obtainment of formula. We can find that seam puckering is related with B, 2HB, G, 2HG5, RC, T among the mechanical properties and the estimated formulas which get from mechanical factors.

The purpose of this study is to verify the mediating effect of empowerment on the relation between job characteristics and creativity. This study also examines the relationship job characteristics and creativity. As a result of this study, job characteristics had positive influence on empowerment. Empowerment had positive influence on creativity. Also job characteristics had positive effect on creativity at first, but it did not have a direct effect on creativity when empowerment was considered. These mean that empowerment is complete mediation variable because job characteristics no longer affects creativity after empowerment has been considered. Several implications, limitations and directions for future research were discussed.

The purpose of this study is to identify the influence of ego integrity on death anxiety of the elderly, mediated by depression based on Erikson theory(1963). For this study, 313 elderly over 60 years old in Daegu city participated in a survey. The data of the survey was analyzed using SPSS 15.0 and Structural Equation Modeling(SEM) with AMOS 7.0. The results of the study are as follows: ego integrity of the elderly does not influence death anxiety due to the suppressing effect of depression. However, depression does mediate the relation between ego integrity and death anxiety fully. Such findings suggest that the Erikson theory can also be applied to elderly Korean citizens. A practical benefit derived from the study's results is the proposition to implement a reminiscence program, reinforce depression treatment and prevention systems, and augment a death awareness movement for elderly.

The purpose of the study is to examine the realities of the child abuse, to analyze the relation between marital conflict and child abuse, and to screen their causes. For the data set 521 elementary school children and mothers living in pusan were chosen. The data were analyzed with the SPSS statistical package using $X^2$, the one-way ANOVA. the factor analysis, and the path analysis. The main results are as follows. Frist, in most of families there are child abuse. Second, among family environmental variables, the father's dissatisfaction with job, the family's social-economic status, violence observation, violence experience influence the child abuse. Third, marital conflict influences marital violence and child abuse, marital violence influences child abuse.

DC influence between pixel electrode and alignment layer (AL) in in-plane switching mode LCD was analyzed through DC equivalence-circuit equation induction, DC charge-discharge simulation, luminance and residual-DC measurement systems using test patterned (TP) cell. DC discharging rate (DDR) of single layer electrode was faster than that of double layer electrode and DDR of low resistance AL was faster than that of high resistance AL. DC discharging characteristics had a close relation to layer number and resistance between two electrodes.
