Individual personality traits are key factors that affect users' self-disclosure on SNS. We examined the relationship between an individual personality trait (i.e., narcissism) and three dimensions of self-disclosure behavior on Facebook (i.e., intention, level, and control of self-disclosure). A total of 261 Facebook users completed an online survey. The findings showed that more narcissistic individuals engage in deeper levels of self-disclosure and do so with greater intentionality than previous research indicated. More interestingly, narcissistic users simultaneously tend to control their expressions in public by concealing who they really are. Overall, these findings suggested that the self-disclosures on Facebook must not investigated by a single dimensions for better understanding of psychological dynamics of it users. In addition, the present research suggested that the narcissism should not be regarded as a predictor which simply gives either a positive or negative influence on self-disclosing behaviors in SNS.

It is presumable that properly designed earcons given simultaneously with visual information could enhance the situation awareness of operators when they are involving in highly complicate process control activities. In this study, population stereotypes of earcons with respect to process control information were identified using 60 Korean subjects. To do this, 11 most distinctive earcons were selected from various earcons having different pitch, rhythm, and timbre. Associations between the selected earcons and 40 pairs of adjectives used to describe the state of control in process were gathered from 37 subjects using a semantic differential method. Based on the results from multivariate analyses, the 40 pairs of adjectives were aggregated into three distinctive semantic dimensions. The emotional maps of the 11 earcons matched with the semantic dimensions were presented in this study. On the basis of these results, a general guideline was suggested for designing earcons to deliver process control information.

This study aims to analyze how pre-service science teachers' reflective thinking is presented during the microteaching process. The subjects of this study were 13 students who attended a lecture course on science teaching methods offered by the Department of Science Education of the College of Education at a national university. The simulated lessons that were performed during the microteaching process went through peer assessment and self-assessment. Then, the next set of lessons was conducted based on the assessment results. After the first set of simulated lessons, the pre-service teachers' reflection at the routine and technical levels was most remarkable in the focus dimension. In the inquiry and change dimensions, technical reflection stood out. Dialogic or transformative reflection was rarely presented. In addition, most of the pre-service teachers displayed mingling patterns of reflection levels in all of the three dimensions. The results of this study, in particular, prove that microteaching has a high level of applicability in terms of reflective thinking and instructional technology. Accordingly, there is a need for subsequent studies to create a new model that can encourage pre-service teachers' reflective thinking by structuralizing peer and self-assessment during the process of microteaching.

The purpose of the study was to examine the effect of internal traits of perceivers on sensory images of fashion materials and dress wearers. Perceiver's internal traits included aspects of Gender-body Ideology (GBI), as well as fashion lifestyles and fashion interest. The research was conducted on a quasi experimental basis, with subjects numbering 187 male and 207 female college students. Data were collected in the period from March 19th to March 31st, 2007. Two sets of stimuli and three measuring tools (to assess GBI, fashion life styles and fashion interest) were used. The stimuli were thirteen fabric specimens and thirteen photographs of dress styles, manipulating by two variables: (a) motif colors (white, grey, pinks and blue); (b) motif categories (plain, paisley, floral, stripes, and zebra effect). The data were analysed by factor analysis, ANOVA, Duncan's multiple range test. The major findings were as follows: Gender-body ideology was separated into agonic and hedonic dimensions. Fashion life style was separated into 3 dimensions(shopping life-style pursuit, social activity pursuits and brand life style pursuits). The internal traits of perceivers influenced preferences and buying intentions. Shopping life-style pursuits had more impact on preferences and buying intentions than other internal traits.

In general, the high temperature superconductors have two-dimensional anisotropic structures. It is important to investigate the dependence of the critical temperature on the dimensions of the electron's motion. The equation of state for electron gas is deduced which describes the electron's motion in superconductors using the kinetic theory of gas. And the critical temperatures of three, two, and one dimensional gases were calculated. According to these equations, restricting the dimension of the electron's motion induces the increase of the critical temperatures. This implies the possibility that the multi-critical temperature of some superconductors is caused by the change of the dimension related to the pathways of the electron.

In the present study, an efficient method for the optimum design of three-dimensional (3D) steel framed structures is proposed. In this method, in addition to choosing the best position of columns based on architectural requirements, the optimum cross-sectional dimensions of elements are determined. The preliminary design variables are considered as the number of columns in structural plan, which are determined by a direct optimization method suitable for discrete variables, without requiring the evaluation of derivatives. After forming the geometry of structure, the main variables of the cross-sectional dimensions are evaluated, which satisfy the design constraints and also achieve the least-weight of the structure. To reduce the number of finite element analyses and the overall computational time, a new third order approximate function is introduced which employs only the diagonal elements of the higher order derivatives matrices. This function produces a high quality approximation and also, a robust optimization process. The main feature of the proposed techniques that the higher order derivatives are established by the first order exact derivatives. Several examples are solved and efficiency of the new approximation method and also, the proposed method for the best position of columns in 3D steel framed structures is discussed.

Self-congruency plays an important role in the context of mothers' shopping for children's clothing because purchasers are inconsistent with users. This study incorporates three dimensions of self-congruencies (congruency between children's image perceived by their mothers and brand image, congruency between mothers' actual self-image and brand image, and congruency between mothers' ideal self-image and brand image) due to purchaser-user inconsistency in children's clothing consumption. A total of 574 mothers with children aged 6 to 10 participated in a web-based survey. Descriptive statistical analysis, factor analysis, reliability analysis and multiple regression analysis were conducted. Self-brand image congruency variables have a different influence on brand attitudes when mothers purchase children's clothing. Brand attitude is influenced positively only when the perceived children's image coincides with brand image and when mothers' ideal self-image corresponds to brand image. In contrast, mothers' actual self-image and brand image congruence negatively influence brand attitude. Further investigation indicates that there are different effects of dimensions of self-congruency on brand attitude according to the characteristics of mothers and their children. This study suggests that when there is purchaser-user inconsistency, different types of image congruence has to be implemented to assess the impact on brand attitudes.

Key aspects of the Norwegian Method of Tunnelling (NMT) are reviewed. These include a predictive method of support design using the six-parameter Q-system of rock mass characterisation. The rock mass rating or Q-value is updated during tunnel driving. The designed tunnel support generally consists of wet process, steel fibre reinforced shotcrete combined with fully grouted, untensioned rock bolts, Even in poor rock conditions S(fr) + B usually acts as the final rock reinforcement and tunnel lining. Since it is a drained lining, it is very economic compared to cast concrete with membranes. Light, free-standing steel liners are used to prevent water affecting the runnel environment. Rock mass conditions, and hence lining design and cost estimation can be assessed by careful use of seismic surveys. Relationships between the P-wave velocity, the rock mass deformation modulus and the Q-value have recently been established, where tunnel depth, rock porosity and the uniaxial compression strength of the rock are important variables. The rock mass modulus estimate, and simple index testing of the joints, provide the key input which joints are discretely represented (either in two dimensions with the UDEC code or in three dimensions with the 3DEC code) is generally favoured compared to continuum analysis. The latter may give a misleading impression of uniformity and deformations tend to be understimated. Q-system NMT designs of S(fr) + B (fibre reinforced shotcrete and bolting) are numerically checked and adjustments made to bolt capacities and shotcrete thickness if overloading is evident around the modelled profile.

The purpose of this study was to identify women's clothing image according to their body image. Self-administered questionnaires were used for data collection. The results were as followed: First, the body image was shown in three dimensions of care for appearance, concern about weight, and appearance attractiveness. And clothing image was shown in seven dimensions of gorgeousness, beauty, sophistication, comfort, confidence, neatness, and feminity. Second, women were segmented into interest in appearance attractiveness group, body image intermediate group, appearance & weight concern group, and body image retard group. Interest in appearance attractiveness group and appearance & weight concern group were found frequently among women in 20s and students or unmarried women, preferred for gorgeousness and feminity of clothing more, and enjoyed internet shopping. Appearance & weight concern group was heavier than interest in appearance attractiveness group. Body image intermediate group were found frequently among women of lower education, and shopped at stores. Third, younger unmarried women preferred for beauty, confidence, and feminity of clothing image and older women preferred for comfort more. Women who preferred for beauty and sophistication of clothing image shopped at internet shopping mall more frequently.

The purpose of this study is to identify the transformational or transactional leadership styles of Korean dietitians. The study was completed with Korean dietitians (n = 268, $67\%$ response) using mail survey. The leadership styles were divided into transformational (including charisma, intellectual stimulation, individualized consideration) and transactional (contingent reward, management by exception) leadership found in the several literature. Overall, the score of Korean dietitians' transactional leadership was higher than that of the transformational leadership (p < .05). Among three sub-dimensions of the transformational leadership styles, the score of 'individualized consideration' was higher than 'charisma' and 'intellectual stimulation'. Between two sub-dimensions of the transactional leadership styles, Korean dietitians used more 'management-by-exception' than 'contingent reward'. ANOVA results suggested that the transformational leadership was more likely to be used by the younger dietitians, while the transactional leadership was more likely to be used by the older dietitians (p < .05). Data showed that dietitians having 3-6 year dietetic experience used more transformational leadership than other experienced dietitians (p < .05). It was also found that the Korean dietitians' leadership styles were influenced by the type of dietetic practice area. Data showed that 'charisma', 'intellectual stimulation', 'individualized consideration' and 'contingent reward' were more likely to be used by Korean dietitians from school than by dietitians from health. care and industry (p < .05). This study will be useful for dietitians to guide the application of appropriate leadership style in order to increase employees' job satisfaction as well as organizational performance.
