Purpose: This study was examined the effects of a hepatitis A education on attitude, vaccination intention, and preventive behavior. Methods: Eighty-eight college students at two universities participated in this study. The data were collected from August 29 to September 30 in 2011 and were analyzed using descriptive statistics, t-test, and ${\chi}^2$ test. Results: There were no significant differences of preventive behavior of hepatitis A between the positive and negative message groups (t=1.10, p=.499). However, the negative message group had a significantly higher attitude of preventive behavior (t=0.92, p=.049) and vaccination intention (${\chi}^2$=5.43, p=.039) than the positive message group. Conclusion: This study demonstrates that negatively framed messages are effective on increasing the attitude, vaccination intention, and preventive behavior.

The purpose of this study was to examine the relationships between adolescent sensation-seeking and risk behavior. This study was based on Zuckerman's model which states that the higher the sensation-seeking score, the higher the risk behavior score. The subjects were 460 third year high school adolescents in Seoul. Instruments were the Arnett Inventory on Sensation-Seeking and questionnaires on risk behavior as well as demographic variables. Statistical procedures were T-test, F-test, correlation, and heirarchical regression analysis. Sex was the only demographic variable related to sensation-seeking scores; there were differences in risk behavior score by father's education, mother's education and father's occupation; adolescent sensation-seeking and demographic variables (father's education, mother's education, and father's occupation) influenced adolescent risk behaviors.

In order to ensure a concrete expansion anchor is suitable for a given application, the load resistance behavior of the anchor must be known. ASTM E488 provides a standard method of testing expansion anchors for static and dynamic loads. Due to the many types of anchors available commercially and the large variability of applications, the ASTM does not delineate all details or requirements necessary to comprehensively determine the dynamic load behavior of concrete expansion anchors. A test program is presented in this paper which was developed and implemented to determine the cyclic load behavior of wedge-type concrete expansion anchors. Test results are also presented along with a discussion of the behavior of anchors, and their suitability for use.

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.

An experimental study of five full-scale coupling beam specimens has been conducted to investigate the seismic behavior of strengthened RC coupling beams by bolted side steel plates using a reversed cyclic loading procedure. The strengthened coupling beams are fabricated with different plate thicknesses and shear connector arrangements to study their respective effects on load-carrying capacity, strength retention, stiffness degradation, deformation capacity, and energy dissipation ability. The study revealed that putting shear connectors along the span of coupling beams produces no significant improvement to the structural performance of the strengthened beams. Translational and rotational partial interactions of the shear connectors that would weaken the load-carrying capacity of the steel plates were observed and measured. The hierarchy of failure of concrete, steel plates, and shear connectors was identified. Furthermore, detailed effects of plate buckling and various arrangements of shear connectors on the post-peak behavior of the strengthened beams are discussed.

This study was carried out to identify users' choice behavior of theme parks. overland. Lotte World, Seoul Land, Dreamland and Children's Grand Park were selected as study areas. Both multinomial logic model(MNL), nested logic model(NMNL) and joint logit model wet$.$e test using a choice-based sample collected on study areas. Hausman-McFadden test showed that the MNL is not appropriate because the IIA assumption is violated. To avoid the problematic IIA assumption, the NMNL was tested. It splits similar alternatives into groups and nests separate decisions into hierarchical order to avoid the IIA assumption. Cluster analysis and discriminant analysis were conducted to find applicable nest structures. The inclusive value coefficient was 0.7788. It meant that sufficient condition of this model is met and users' choice behavior can be better understood by NMNL than MNL. The $\rho$2 value and accuracy of prediction of this model were 0.402 and 46.33% , respectively. Several comments were suggested to make the NMNL to be more reliable for future research on users' choice behavior of theme park.

Although magnesium has high potential for structural material due to the lightweight and high specific strength, the structural application has been limited by the low ductility at room temperature. The reason of the poor ductility is few activated slip systems of magnesium (HCP structure) during deformation. As temperature increases, however, additional non-basal slip systems are incorporated to exhibit higher ductility comparable to aluminum. In the present study, a series of tensile tests of Mg-Al alloy has been carried out to study deformation behavior with temperature variation. Analysis of load relaxation test results based on internal variable approach gave information about relationship between the micromechanical character and corresponding deformation behavior of magnesium. Especially, the material parameter, p representing dislocation permeability through barriers was altered from 0.1 to 0.15 as the non-basal slip systems were activated at high temperature.

Many parameters influence the frictional behavior of steel sheet during stamping. The contact pressure between a die and a sheet during stamping is one of them. Thus, this parameter is investigated for high strength steel (HSS) sheets, which are widely used for auto body panels due to their potential for weight reduction. Since HSS extend the limits of contact pressure for mild steel, the effect of this parameter on friction cannot be ignored. To investigate the influence of contact pressure on the frictional behavior of steel sheets, a flat type of friction test was conducted on three different steel sheets under various contact pressures. For bare steel sheets, the curve representing the relationship between contact pressure and friction coefficient exhibits a U shape. Coated steel sheets show a similar tendency except at low contact pressure. For these materials, when the contact pressure is very low, the friction coefficient slightly increases with pressure before it starts to decrease. The test results show that the effect of contact pressure on frictional behavior of steel sheet is not negligible even for contact pressures that are lower than the strength of HSS sheet.
