The purpose of this study is to empirically identify the effect of women's motivation for choosing makeup colors on their perception of physical attractiveness and self-respect. Participants in this study were surveyed through questionnaires for 256 employees in Seoul and Gyeonggi-do, and the collected data were analyzed in depth using statistical analysis methods of frequency analysis, factor analysis, and multiple regression analysis. The results derived through a series of research procedures are as follows: First, the motivation for women in the workplace to choose makeup colors showed a statistically significant influence on physical attraction perception. Second, the motivation for women in the workplace to choose makeup colors showed a statistically significant influence on self-esteem. Third, office workers' perceptions of physical attraction had a statistically significant impact on self-esteem.

In this study, we investigated the effect of users' emoticon usage on their satisfaction with image making and self-expression in MIM communication. We defined internal attraction, social appeal, and communication ability as personal image making factors due to the use of emoticons in MIM communication. And we defined the research hypotheses based on the definition of intimacy, openness, and social reality as relational image making factors. In MIM communication, we analyzed the questionnaire about emoticon users. As a result, emoticon usage was found to have a positive and significant effect on self-expression in relation image making rather than personal image making. The study implies that the use of emoticons can lead to image making in MIM communication and satisfy the satisfaction of self expression.

In order to investigate the stability of magneto-rheological fluid based squeeze film damper (MR-SFD), its negative stiffness effect, which arises from magnetization of MR-SFD, is identified theoretically and experimentally. The analytical model of MR-SFD includes the magnetic circuit as well as the displacement stiffness associated with the squeeze mode of MRF. Extensive experiments are carried out to measure the magnetic attraction forces generated in the MR-SFD, with the excitation frequency and the eccentricity of the journal varied, which are controlled by an active magnetic bearing. The simulation and experimental results are found to be in good agreement. It is concluded that the negative stiffness effect dominates only in the low frequency region because its effect diminishes in the high frequency region due to the eddy-current loss.

This research, targeting the visitors to Hahoe Village at Andong, which is a cultural tourist attraction with its traditional cultural heritage well preserved, aimed at offering applicable implications to the staff in charge of management of Hahoe Village at Andong by clarifying which cultural tour experience factor has an effect on touring satisfaction and visitors' behavioral intention as a follow-up attitude from touring satisfaction, i.e. effect relationship between the intention of re-visit and intention of recommendation in a structural viewpoint. To sum up this research result, first, there are two factors of cultural tour experience: education and escape. These were found to have a positive effect on touring satisfaction. Second, four factors of cultural touring experience was found to have a positive effect on visitors' behavioral intention. Third, touring satisfaction was found to have a positive effect on visitors' behavioral intention

This study was performed to ascertain the three-dimensional effect of the crack reduction and the restrained effect of crack growth, and to yield a suitable mixing ratio of the synthetic fiber reinforced soil. The results of the study are as follows ; 1) The synthetic fiber has the resisting force for crack because of the adhesion due to the attraction of soil particles. 2) As the synthetic fiber length and the mixing ratio are increased, mono filament synthetic fiber reinforced soil is increased the effects of crack reduction and the restraint of crack growth. 3) The fibrillated synthetic fiber is more effective than mono filament synthetic fiber for crack. 4) A suitable mixing ratio of synthetic fiber reinforced soil is 0.5% of the fibrillated synthetic fiber.

The ion adsorption on an aligning layer deposited onto a conductive electrode in a liquid crystal (LC) cell has been shown to depend strongly on the dielectric constants of the layer and its thickness d. Calculations made in the framework of the three-layer electrostatic theory showed that, depending on those and other intrinsic parameter of the problems, it is possible to observe either ion attraction or repulsion at the aligning surface. Tentative measurements of the ion adsorption dynamics on the aligning layers with various d qualitatively agree with the theory. The results obtained allow the memory effect in LCs and the sticking effect in LC displays (LCDs) to be controlled effectively.

In this paper, the conventional linear induction motor(LIM) used in propelling the MAGLEV in Korea is redesigned in order to reduce its weight. The specifications of the newly designed model for base speed, acceleration, rated thrust and maximum output is respectively 45km/h, 4.0km/h/sec, 5,200[N] and 65 [kW]. Weight reduction effect of the LIM according to the change of pole number from 8 to 6 is shown. Equivalent circuit analysis considering end effect and finite element method are used for the analysis of the redesigned model. Finally the weight reduction ratio of the newly designed LIM to the conventional model, thrust, attraction force, line current, temperature rise, flux density distribution are presented.

The purpose of this study is to analyze the effect of media on makeup and hairdressing behavior. The data collected for this study were gathered through questionnaire survey with 443 female students in Seoul. The first study focus is on makeup behavior. The ANOVA test reveals that those exposed to magazine show higher level of concern with makeup compared to those exposed to other types of media. Using logistic regression method, we find that those exposed to magazine or those with positive body image are more likely to take makeup course. The next focus is on hairdressing behavior. The ANOVA test reveals that those exposed to magazine show more frequent use of hair salon. They also spend more money on hairdressing. The regression analysis also shows that those exposed to magazine or those with sexual attraction visit hair salon more frequently than others.

Particle transport and deposition characteristics on semiconductor wafers inside the chamber were experimentally investigated via a particle generation & deposition system and a wafer surface scanner. Especially the relation between particle size($0.083{\sim}0.495{\mu}m$) and particle deposition velocity with ESA(Electrostatic Attraction) effect was studied. Spot deposition technique with the deposition system using nozzle type outlets of the chamber was newly conducted to derive particle deposition velocity and all experiment results were compared with the previous study and were in a good agreement as well.

In this study, we investigated the pure geometrical effect of porous materials in gas adsorption using the grand canonical Monte Carlo simulations of primitive gas-pore models with various pore geometries such as planar, cylindrical, and random pore geometries. Although the model does not possess atomistic level details of porous materials, our simulation results provided many insightful information in the effect of pore geometry on the adsorption behavior of gas molecules. First, the surface curvature of porous materials plays a significant role in the amount of adsorbed gas molecules: the concave surface such as in cylindrical pores induces more attraction between gas molecules and pore, which results in the enhanced gas adsorption. On the contrary, the convex surface of random pores gives the opposite effect. Second, this geometrical effect shows a nonmonotonic dependence on the gas-pore interaction strength and length. Third, as the external gas pressure is increased, the change in the gas adsorption due to pore geometry is reduced. Finally, the pore geometry also affects the collision dynamics of gas molecules. Since our model is based on primitive description of fluid molecules, our conclusion can be applied to any fluidic systems including reactant-electrode systems.
