To study the vibration characteristics of a high-speed railway continuous girder bridge-track coupling system (HSRCBT), a coupling vibration analysis model of an m-span continuous girder bridge-subgrade-track system with n-span approach bridge was established. The model was based on the energy and its variational method, where both the interlaminar slip and shear deformation effects were considered. In addition, the free vibration equations and natural boundary conditions of the HSRCBT were derived. Further, according to the coordination principle of deformation and mechanics, an analytical method for calculating the natural vibration frequencies of the HSRCBT was obtained. Three typical bridge-subgrade-track coupling systems of high-speed railway were taken and the results of finite element analysis were compared to those of the analytical method. The errors between the simulation results and calculated values of the analytical method were less than 3%, thus verifying the analytical method proposed in this paper. Finally, the analytical method was used to investigate the influence of the number of the approach bridge spans and the interlaminar stiffness on the natural vibration characteristics of the HSRCBT based on the degree of sensitivity. The results suggest the approach bridges have a critical number of spans and in general, the precision requirements of the analysis could be met by using 6-span approach bridges. The interlaminar vertical compressive stiffness has very little influence on the low-order natural vibration frequency of HSRCBT, but does have a significant influence on higher-order natural vibration frequency. As the interlaminar vertical compressive stiffness increases, the degree of sensitivity to interlaminar stiffness of each of the HSRCBT natural vibration characteristics decrease and gradually approach zero.

The purpose of this study was to explore variables that influence mother-adolescent conflict. Independent variables were adolescent's physical maturation, mother's self-esteem, and mother-adolescent communication pattern. The results were as follows: First, the degree of mother-adolescent conflict perceived by adolescents was low in general, but high in homework and academic achievement. Second, no sex difference was found in the degree of mother-adolescent conflict. Third, the mother-adolescent conflict was not significantly related to both of adolescent's physical maturation and mother's self-esteem. However, mother-adolescent communication meaning that the more open the communication between mother and adolescent was, the less conflict was found between them.

This research examines how consumer preferences for products are affected by attribute resemblance, which refers to the degree to which a product is similar with other products that are being evaluated together. It is expected that the influence of attribute resemblance on attitude and choice is moderated by attribute familiarity, which is tested in three empirical studies. Studies 1 and 2 examine the effects on the attitude toward the product and show that the positive influence of attribute resemblance on attitude is stronger when attribute are less (vs. more) familiar. Study 3 tests the effects on choice for which attribute resemblance can have a negative influence because of the increase in the competition with similar options. For choice, the attribute resemblance has a positive influence when attributes are less familiar but has a negative influence when attributes are more familiar.

영화관 발전 이유는(보통 영화,3D MIX,4D)관중 시청각 효과가 위해서 발전한다. 이제 까지 최고한 시청각 효과 받을 수 있는 기술을 $VR360^{\circ}$ Degree panoramic video촬영 기술 밖에 없다. 하지만 이 기술을 전통 영화 촬영 기술 보다 완전히 다르다. 이 기술 영화 방면 운용하면 원래 영화적 이론 크게 충격 받다.

The purpose of this study was to examine the emotional experience dimension on the brand of the low price cosmetics and to empirically investigate the effect of emotional experience on the relationship between customers and brand. Data were collected for 10 days starting on March $2^{nd}$ 2009. Questionnaires were distributed to 517 female college students who experienced to purchase the products of the low price cosmetic brand and answers were collected. The results of analysis on collected data showed that the emotional experience was classified into sense, spatial environmental emotion, sales promotion emotion, salesperson emotion and visual/verbal identity, and emotional experience on low price cosmetic brand had a positive effect on the relationship between customer and brand. Specifically, it was showed that emotional experience on low price cosmetic brand significantly affected the customer satisfaction, brand trust and brand attachment. In terms of effect of emotional experience on customer satisfaction, the orders in the degree of influence were following: the sense, spatial environmental emotion, sale promotion emotion and salesperson emotions. In terms of effect of emotional experience on brand trust, the orders in the degree of influence were following: the sense, salesperson emotions, sale promotion emotion and spatial environmental emotion. In terms of effect of emotional experience on brand attachment, the orders in the degree of influence were following: the sense, spatial environmental emotion, salesperson emotions, visual/verbal identity and sale promotion emotion.

최근 스마트폰 스파이웨어는 PC의 여러 가지 유형의 바이러스 요소들을 닮아가고 있으며, 점점 심각해지고 있는 추세이다. 또한 스마트폰 스파이웨어의 성장속도에 비해 스마트폰의 보안과 관련된 측면들은 매우 취약한 상태이지만 사용자들은 그러한 위험 요소들을 심각하게 인지하지 못하고 있는 실정이다. 이에 본 연구는 개인적 성향과 스파이웨어에 대한 인식을 바탕으로 정보보안이 스마트폰 선택에 미치는 영향을 살펴본다. 연구 모델의 주요 변수는 독립 변수로 개인별 위험성 감수정도와 스마트폰 스파이웨어 위험성을 선정하고, 종속 변수로 스마트폰 구매 의향을 설정하였다. 현재 스마트폰을 사용하고 있는 사용자를 대상으로 설문조사를 통해 얻은 200부의 유효한 자료를 SPSS 21 통계 프로그램을 이용하여 검증하였다. 연구결과에 의하면 개인별 위험성 감수정도에 따라 스마트폰 스파이웨어의 위험성을 인지하는 것과, 스마트폰 스파이웨어의 위험성을 인지할수록 스마트폰 구매의향에 영향을 미치는 것으로 나타났다. 즉, 스마트폰을 선택할 때 정보보안의 영향을 파악할 수 있었다.

The number of the functionally disabled elderly has been increasing in Korea and their families should have been in charge of supporting and taking care of them. This study was designed to grope for devices which were helpful to improve the psychological welfare of the functionally disabled elderly in the present situation. The results of this study were as follows: First, considering the level of psychological welfare of the functionally disabled elderly, the depression degree of the subjects was 52.9 which was higher than the middle point, 50. And the degree of family support the functionally disabled elderly were aware of, it also was high ; the score was 34.6 compared to the middle point, 33. On the other hand, the degree of public support that the functionally disabled elderly received was 2.01 which was lower than the middle point, 4.5. Second, the level of the depression of the functionally disabled elderly followed by background variables, the degree of agreement with family support, and public support represented significant differences among group according to religion, the type of previous occupation, the ownership of house, the type of residence, the presence of spouse, education level, and the source of income. Third, the relative influence toward the depression of the functionally disabled elderly was shown in the order of importance as follows: family support, the degree of functional disability, the ownership of house, public support, the presence of spouse, the source of income, the number of daughters, the degree of functional disablity.
