This paper investigated materialism inclination of the parents recognized by the adolescents and analysed the relationships between 5 categorized types about parents' materialism inclination and financial characteristics of the adolescents. Statistical analysis was achieved by using Cronbach'$\alpha$, paired t-test, one-way ANOVA, two-way ANOVA, Duncan's multiple range test, chi-square analysis, and Ward' hierarchical cluster analysis with a total of 801 questionnaires. The results are summarized as follows: First, the adolescents felt that calculated points of father and mother's materialism inclination were lower than median points and mother's inclination for materialism was higher than that of father. Second, five categories were classified according to materialism inclination of parents. First classified category was the type which showed both parents had little interest in materials and the second category was the type which father had strong interest in materials. The third one was the type which mother had strong interest in materials. The last two categories were the ones which both parents had much interest in materials. Final result of this study revealed that attitudes of the adolescents for materialism and money were higher for those whose parents had strong interest in materialism than those whose parents had little materialism interest. They showed not only the behaviors of impulsive and overspending consumption but also low financial satisfaction and high financial stress.

Objective : This study investigated the temperament and character traits associated with suicide attempts in patients with mood disorders. Methods : The temperament and character inventory (TCI) was administered to 150 patients who visited psychiatric clinics seeking treatment for mood symptoms. The patients were divided into three groups as follows : non-suicide ideation, suicide ideation and suicide attempt. We also gathered socio-economic data in order to rule out confounding variables. MANOVA was performed to analyze differences in personal temperament and character scores on the TCI between the three groups. Results : The self-directedness and cooperativeness subscales of the TCI are most influenced by the clinical symptoms rated by Beck Suicide Ideation Scale and Hamilton Depression Rating Scale. In the temperament scale, the suicide attempt group scored higher on the novelty seeking and harm avoidance items than the other two groups. The specific temperaments associated with suicidal behavior in patients with depression are impulsivity (NS2) and anticipatory anxiety or pessimism (HA1). Conclusion : In this study, we found that more risky patients who had previously attempted suicide had a temperament of impulsivity or pessimism. This finding suggests that a more cautious approach is needed to assess mood disorder patients with impulsive or pessimistic temperaments in order to prevent suicide attempts.

In this paper robust nonlinear image denoising algorithms are introduced for the distribution which is Gaussian in the center and Laplacian in the tails. The distribution is known as the least favorable ${\epsilon}$-contaminated normal distribution that maximizes the asymptotic variance. The proposed filter proves to be the maximum likelihood estimator under the heavy-tailed Gaussian noise environments. It is optimal in the respect of maximizing the efficacy under the above noise environment. Another filter for reducing impulsive noise is proposed by mixing with the myriad filter to propose an amplitude-limited myriad filter. Extensive experiment is conducted with images corrupted with ${\alpha}$-stable noise to analyze the behavior and performance of the proposed filters.

Department store has actively expanded cultural center services by providing a series of educational courses in order to increase customer visits, enhance customer satisfaction, and ultimately increase sales. In this study, cultural center members' shopping behaviors and image building of the department store were explored through focus group interviews. Results generated from a total of 7 focus group interviews with female cultural center members in their 30's through 60's are as follows. First, the consumer group who attends courses for their own purpose is 45 to 55 year-old female customers who are actively involved in consumption at the department store for their own clothing, food and restaurant. They are not often engaged in impulsive either group shopping for clothing. They are satisfied with class quality compared to low tuition whereas dissatisfied with busy schedule of a lecture room and lack of special discount benefits for members. Second, the other consumer group who attends courses for their children is consumers in their 30's. They are charged in shopping for clothing for their husbands, children, and themselves. They are suffering time poverty due to nurturing their children, therefore, they want to shop more in the department store on the day of class. However, expensive kids-care facilities are barriers to do it. Convenience, familiarity and center of culture are important images of the department store, developed through frequent visits of these customers. Eight implications for marketing strategies were generated based on study results.

Blast load, an impulsive load with extremely short time duration with very high pressure, is effected by ground and air condition, weight of charge, shape and location of structure. In this study, a blast dynamic analysis for the air-structural integrated model considering dynamic properties of materials and simulation of complex blast wave propagation by Arbitrary Lagrangian- Eulerian technique is suggested to perform an accurate blast analysis of concrete structures. For the verification of the proposed blast analysis method, which is the air-structure integrated model using ALE technique, the comparison of analysis and experimental results is performed. The verification confirms that the simulation of realistic behavior of RC wall structures is possible using ALE method. Also, the example cases which have been analyzed using this method show that the estimation to the structural failure criterion for blast load failure can be represented by energy absorbtion procedure.

The purpose of this study is to investigate the differences in consumer clothing shopping orientation and shopping behaviors by the multi-selection of internet and offline stores. The data were collected from 201 men and women in their twenties and the respondents were grouped into three as internet-store users, multi-store users, and offline-store users. The data were analyzed using factor analysis, ANOVA, post-hoc analysis, frequency analysis, and chi-square analysis. The results are as following. First, the clothing shopping orientation was partly different among the groups. Regarding the offline shopping orientation, the groups showed difference in the impulsive orientation, and regarding the online shopping orientation, the groups showed differences in the goal oriented and enjoying orientation. In all the three cases, the internet users showed strongest orientation, and the next were multi-store users and offline-store users. The cause of these results were explained as the familiarity and experience with the channel. Second, the clothing shopping behaviors were also partly different among the groups. The groups showed no differences in the preferred store type and benefits sought, but showed significant difference in the attitude toward the internet shopping. The internet-store users showed most positive attitude, and the next were multi-store users and offline-store users.

A force cancelling observed to control the vibration of a single degree of freedom elastic system subjected to an arbitrary, unmeasurable disturbance is considered in this paper. The main idea of a force cancelling observer is how an estimate of the excitation can be derived and used to generate a control force which reduces the vibration. This control is shown to be robust with respect to the parameters describing the behavior of the system. Experimental and numerical results are presented which show the efficacy of the observer when the system is excited by periodic, random, and impulsive torques.

In "Adventure" Alice Hindman tries to express her repressed sexual instinct with impulsive adventures but becomes a grotesque through her own self-deception and extreme loneliness. She has a passionate relationship with Ned Currie at 16, which defines her identity and molds her entire life. She does believe that Ned may return and stick to his disingenuous word and promises, and holds on to it as the only and absolute truth in her life. Her distortion of reality is in fact based on her self-deception and falsehood she creates. Seized by a strange urge, her second adventure indicates that she wants to feel closer to another grotesque that can understand her loneliness, and that her desire for communication transcends her sexual desire. At the end of the story, she seems to realize that she will die in her bed alone, misunderstood and unloved. But this conclusion shows that, despite the opportunity and potential of another choice, she never makes positive choices and refuses to accept responsibility for her actions. She rather creates an excuse with empty words and shows the limits so as not to get out of her own self-deception. Instead of focusing on Alice's strange behavior and blaming her, Anderson emphasizes the importance of understanding and communication while exploring the sorrow and loneliness of a woman who wants to be loved but is obsessed with self-deception in Winesburg.

Background: Many patients with complex regional pain syndrome (CRPS) have been known to be at risk of suicide, due to severe pain and its comorbid conditions. The risk of suicide may be associated with affective instability, which is an indicator of emotional dysregulation. Particularly, unstable shifts in negative emotions are difficult to cope with, which may result in individuals feeling uncontrollable, hopeless, and entrapped. This study aimed to examine the role of affective instability in the relationship between pain intensity and suicide risk (suicidal ideation and impulsivity) in patients with CRPS, by employing a daily diary. Methods: Twenty-three patients registered at the CRPS Association in Korea were asked to complete a day-to-day routine for 15 days, followed by a diary composed of pain intensity, suicidal ideation, impulsivity, and positive and negative affects. Results: Results showed that the interactions between negative affective instability and daily pain intensity were statistically significant on daily suicidal ideation (coefficient = 0.41, t (21) = 2.56, P < 0.050) and daily impulsiveness (coefficient = 1.20, t (19) = 3.35, P < 0.010). However, those between positive affective instability and daily pain intensity were not. Conclusions: This study is the first attempt to investigate the role of affective instability on the relationship between daily pain intensity and daily suicide risk in patients with CRPS. Our findings suggest that health professionals pay considerable attention to the instability of negative affects when assessing and managing patients with CRPS at risk of suicide.

A simplified method for earthquake response analysis of a rectangular liquid storage tank is proposed with fluid-structure interaction considered. In order to simplify the complex three-dimensional structural behavior of a rectangular liquid storage tank, it is assumed that structural deformation does not occur in the plane parallel to the direction in which the earthquake ground motion is applied but in the plane perpendicular to the direction. The structural deformation is approximated by combining the natural modes of the simple beam and the cantilever beam. The hydrodynamic pressure, the structure's mass and stiffness, and the hydrodynamic pressure's added mass are derived by applying the Rayleigh-Ritz method. The natural frequency, structural deformation, pressure, effective mode mass, and effective mode height of the rectangular liquid storage tank are obtained. The structural displacement, hydrodynamic pressure, base shear, and overturning moment are calculated. The seismic response analysis of an example rectangular liquid storage tank is performed using the proposed simplified approach, and its accuracy is verified by comparing the results with the reference solution by the finite element method. Existing seismic design codes based on the hydrodynamic pressure in rigid liquid storage tanks are observed to produce results with significant errors that cannot be ignored.
