  • This study analyzes gender bias in children's informational books about science and science careers to determine how these early resources are affecting the disparity between males and females in science and engineering fields. The study focused on the number of male and female scientists both in pictures and text, and how much space was devoted to discussion of scientists of each gender. Overall, the findings of the study show that only 18% of the pictured scientists were female as well as only 16% of the scientists discussed in the text. These numbers are below current industry data that puts the number of females working in science and engineering fields at 26%.

  • We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About 20 episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

  • Porous media have especially large surface area per volume, which contain complex fluid passage. If porous media can be applied to cool a CPU or an electronic device with large heat dissipation, it could result in heat transfer enhancement due to the enlargement of the heat transfer area and the flow disturbance. This study is aimed to identify the heat transfer and pressure drop characteristics of high-porosity metal foams in a horizontal channel. Experiment is performed with the various heat flux, velocity and pore density conditions. Permeabilities, which is deduced from Non-Darcy flow model, become lower with increasing pore density. Nusselt number also decreases with higher pore density. High pore density with same porosity case shows higher pressure loss due to the increase of surface area per unit volume. The fiction factor decreases rapidly with increase of Reynolds number in Darcy flow region. However, it converges to a constant value of the Ergun coefficient in Non-Darcy flow region.

  • To put it simply, thing theory is a study of meaningful capacities of materiality. Although T. S. Eliot regarded pathetic fallacy as the bad example of objective correlatives in his modernism poetry theory, it is clear that many objects in literary works reflect diverse human desires. Among many, Victorian sensation novels are the most distinct genre where the various paraphernalia in them indicate the distorted and exaggerated greed of the industrial revolution era. Whereas the male protagonists are usually related with the norms objects of authority such as portrait and locket, the female characters' connection with cosmetics and white dress shows their oppressed and fragile position in the patriarchal and hierarchical society. In the (post)modern society, the ambiguity of things has grown rapidly due to the increasing discrepancy between objects and things. In special, the new journalism and the psychological realism novels often reveal the post-truth phenomenon because consumerized audience depend more upon the attraction and affect than the mere evidence and facts. For the individual, according to object relations theory, these alternative facts are rather internalized into their mind as the internal object when they are motivated by the non/contact with primary caregivers in their childhood. The dominant material imagery in (post)modern fiction becomes the site of resistance because of their reconstructed and extended meaning. The object relations theory and thing theory can be effectively used to uncover the complicated meanings of desired objects by using the human-object's meaningful relations and early mental images that are secretly alive still in the present.

  • In this study, friction tests were carried out in order to investigate the friction behavior of textured surface in unlubricated state using ball-on-disk type apparatus. Test specimens were SUJ2 bearing steel ball and SM45C steel disk. Square arrays of circular micro-dimples were created on the surface of disk specimen by Nd:YAG Laser. Friction tests were performed for the disk specimen with various micro-dimple parameters and was also conducted for the variation of normal loads and relative velocities. The results showed that fiction coefficient of textured surface was lower than that of non-textured surface and the deeper depth of micro-dimple was, the lower friction coefficient obtained at the same diameter of micro-dimple in unlubricated state. Area density of micro-dimple had an effect on the friction coefficient. It was also found that friction coefficient generally decreased with the increase of normal load and relative velocity.

  • The fashion advertisement is communication method between clothing and consumer. The development of mass communication accelerated that In modern society Post-modernism advertisement is a specialized and separated from so it confuses the consumers who are used in traditional AD. The peculiarities (non-form, destruction of description, compound of genre, mixing of reality and fiction) are more reflected in fashion advertisement. The sample consisted of 425 mail and female and the results were analyzed using frequency and percentage calculation Close tabs T-Test Oneway Anova Factor analysis Chi-square Test, Regression, Correlation Analysis. The result of this study were as follows: The post-modernism fashion ad is the separated and reflected from for young age's favorite. By the factor analysis of consumer response in each 5 emotional factors proved to be valid ones(fine, negative, sexual, stimulative, constructive aspects.) The fine and negative aspects of the factors are very concerned with the consumer's favorite attitude of fashion ad. There is no significant difference in age job but sex has a significant difference. In according to the method of the ad expression consumer's acceptance is difference in sex. There were no significant concern with excess effects and purchase intend in fashion advertisement.

  • The purpose of this study is to evaluate the friction coefficients between abutment materials and clasp materials, and to an estimation formula for retention force. The coefficients of friction between three clasp materials and four abutment materials were measured under various conditions, polished and sandblasted and wet and dry. The measurement was repeated for each combination up to a total measurement of 1200 times. Estimation formula for retention force is measured as sum of two terms, which the one time is proportional to the product of friction coefficient ${\mu}$ and undercut u and the other term is proportional to u-squared. Two proportional coefficient were obtained by least square method. The results are as follows: 1. Friction coefficients were ranged from 0.08 to 0.53 under various conditions. 2. Friction coefficients of non-metal abutment materials are greater in wet conditions than dry conditions. 3. Friction coefficients of sandblasted clasp against abutment are greater than that of polished clasp. 4. Clasp retention force can be estimated with the model as F=$F_d(3.0{\mu}u+1.5u^2/h)$ with minor error.

  • The purpose of this study was to assess the performance of Korean public libraries based on the national representative sample using Vakkari and Serola's (2012) public library outcome scale. Conducting a web-based survey to 1,000 Korean adults nationwide, the responses of 629 respondents who had visited the public library in the past year were analyzed. Results showed that, among the 19 benefit areas, "reading fiction and non-fiction" was the most perceived benefit area followed by "acquiring educational opportunities", and "self-development during leisure time". The benefits were considerably lowly perceived in the rest 16 areas. Different from the original four-factor structure, "reading/self development" were emerged as a new factor in this Korean sample. The benefits were perceived differently by citizens with different socio-demographic backgrounds. Results informed the current status of the public library performance and values perceived by the general Korean adults population across the nation.

  • This study has attempted to explore the way to construct the reality and its implication of the narrative elements in TV Audition Reality Show. According to the study results, first of all, two audition reality show has added the special tasks to characters based on the competition and has developed the dramatic events sequentially. And they has suggested the course of way between survival and fail, that is, inclusion and exclusion. As that results, audiences has be immersed in the process of the justification of the star(hero) myth and the dealings of musical elements to see dramatized show of narrative. And they knew audition reality show as non-real fiction, so they enjoyed the pleasure spontaneously. These means that the empowered media reproduced the illusion like star(hero) with the purpose of the commercial and political aim and one of the ideology to acquiesce in the appropriateness of the competition.

  • This article reviews the film acting studies of Kracauer presenting the basic approach of traditional film theory. It is to provide a foundation for film acting theory in order to activate the domestic acting studies. While Kracauer explaines the difference between traditional stage actor and film actor in 'Remarks on the Actor' of Theory of Film(1960), he suggests the characteristics of the cinema acting and its media technical meanings. He emphasizes the acting forms presenting the postwar new realism in his film acting studies. His approach takes the perspective of 'physical reality' or 'camera reality' which is the basic premise of film theory. Kracauer insists the naturalness of the actors, listing the features of professional actors, non-professional actors and Hollywood stars as they are a familiar classification for the types of actors. He does not prefer the Hollywood stars, whether it is fiction or documentary, professional or non-professional actors, but he emphasizes negative acting, the ability to express words by doing nothing, based on indeterminacy or indefiniteness of the film. Kracauer's film acting studies has affected later film theory and media-related acting, and has become the principles of cinema textbook and acting.
