  • The purpose of the study was to investigate the effect of explanation in conjunction with gravity and density on students' alternative conceptions for floating and sinking phenomena. The subjects were 140 students of 11th grade in 4 classes of a high school located in Gangwon Province. We divided them in two groups; comparison and experiment. The students of experiment group learned explanation in confection with gravity and density. The students of comparison group learned explanation of pressure as represented in physics textbook. ANCOVAs (analysis of covariance) were conducted using the pretest as a covariance. In items related to characters of matter, 2 items are not significant and only 1 item has significant small effect size (Hedges' g=0.327). In the change of alternative conceptions, there is no meaningful gap between two group. However, in items related to relative weights between object and water, the all items have significant effect sizes (0.286~0.502). In addition, frequency of experiment group's alternative conceptions related to pressure decreases considerably, but comparison group does not. Therefore, the explanation in conjunction with gravity and density suggested in this study can decrease students' alternative conceptions related to floating and sinking phenomena and increase scientific conceptions.

  • The purpose of this study is to typify femininity and masculinity represented in mainstream women's and men's fashion magazines in Korea since 2000 and infer sexual ideology appearing in contemporary Korean society by content analysis with the view of plural sexuality. For the content analysis total 259 editorial fashion photography was analyzed. As the result, 5 femininities and 5 masculinities were typified, and then sexual discourse was inferred out of the frequency of each type and texts with the images. On the basis of previous studies and historical considerations of this topic, the types of sexuality represented in mainstream fashion magazines in Korea since 2000 were classified as follow.: in women's fashion magazines Traditional Femininity and Androgynous Femininity were almost similarily dominant sexuality, and Glamor Femininity, Babydoll Femininity, and Genderless sexuality were alternative. Meanwhile, in men's fashion magazines Traditional Masculinity formed clear dominant sexuality, and Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity, and Genderless sexuality were alternatives. In addition, Androgynous Masculinity in women's fashion magazines occupied the highest frequency, while Glamor Femininity in men's fashion magazines did so. From this sexual discourses represented in mainstream fashion magazines in Korea since 2000 are as follow.: First, mainstream fashion in Korea sticks to the modern values preserving traditional sexual ideology even in this postmodern period of the former 21C. Second, Androgynous Femininity as another dominant femininity with Traditional Femininity connotes the change of conception of femininity in Korean society. Third, Androgynous Masculinity to females is preferred, while femininity to males is still regarded as fetish or adorned object. Fourth, the appearance of various alternative sexualities leads to pluralization of sexuality, and then fashion gradually codifies youthfulness and feminine values, such as body and sexual desire more than before.

  • This study aims to organize the research ways of interior design for clothing stores as a management strategy in the market changing rapidly. The public met their needs in a mass production system. However, the brand-name companies began to create the conditions of consumption for people, there appeared people with new lifestyles and new way of thoughts so that their propensity to consume resulted in consumption activities, and it become varied, individual, and highly qualified. Therefore, in view of consumers' priority, based on SI sales environment this paper aims to create a new image by re-designing the interior and furniture of shops which will help to enhance the image of brand name. Therefore, the brand-name companies will expect a large sale for the new product and it will apply to sales environments of other products and influence them. The purpose of this paper is to find a desirable way to increase sales efficiency for the companies. In order to get a concept and propriety of sales environment design, examined mutual relation to each study of interior design, marketing, and fashion design. Through referring to the documents research of these fields I could get a conception and basic structure for them. Based on the theoretical knowledge, this study was made to show to examine and generalize the existing sales environments and situations and set up a new concept for this. It will apply to interior design and store holds and present a new design alternative for improvement.

  • This study proposes a new instructional strategy and corresponding materials designed from various alternative frameworks to help students understand evolution as a biologically acceptable theory. Biology teachers have normally taught the evolutionary mechanism by means of comparing Lamarckism with natural selection. In this study, a new instructional strategy in which the Lamarckian explanation is first excluded because Lamarckism is known to be subsumed in a learner's cognitive structure as a strong preconception of evolution is suggested for teaching evolution. After mutation theory is introduced, Darwinism including natural selection is explained separately during the next class hour. Corresponding instructional materials that aid student understanding of the evolutionary mechanism were developed using recently published articles on human genetic traits as scientific evolutionary evidence instead of the traditional evolutionary subject matter, giraffe neck. Evolutionary evidence from human genetic traits allows students to exclude anthropocentric thoughts effectively and raise concern for the phenomenon of evolution positively. The administered instructional strategy and materials in this research improved student conception, concern, and belief of evolution and it is believed that they helped students understand the evolutionary mechanism effectively.

  • What prevails in the today's research on social media is a functional view of technology. Technology is regarded as a set of technical devices used to conduct specific social functions, such as personal communication, social networking, public posting, and corporate advertising, among others. This paper proposes that such a functional view of technology renders social media research unduly limited and constrained in its scope, level, and direction of inquiry. Problematizing on some representative social media research efforts in the field of IS, this paper provides an alternative perspective, that is, to view social media as a technology-for-being that exerts a deeper level of influence on our existence, molding and shaping the nature and mode of being itself. Such a technology-for-being perspective has been rarely explored or subscribed to in the present IS social media research. Building upon the new conception of social media as a technology-for-being, this essay explores the quality of being in the context of social media. Five such qualities are discussed, including virtuality, materiality, externality, liquidity, and hybridity. The essay also explores the deep structural problems of research to guide future social media research. Six of such problems include Problematize-the-Natural, Follow-the-Actor, Welcome-the-Frankenstein, Weber-meets-Frankenstein, Freud-meets-Frankenstein, and Marx-meets-Frankenstein. The essay concludes with discussions on the implications of the essay, its limitations, and suggestions for future work.

  • Sexual behavior is crucial in life, yet comparatively little is known about the mechanisms in the sexual response in humans. A lot of theories and models have been developed to explain about the process of the sexual response in humans. The first model of sexual function was described by Masters and Johnson, defined the four-phase model (phases of excitation, plateau, orgasm and resolution). Helen Kaplan proposed a slightly different model of human sexual response by adding the conception of the desire phase. Some years later, a new model of circular sexual response pattern was described by Whipple and Brash-McGreer, who acknowledged the cyclic nature of women's sexual response. Basson presented an alternative model of women's normative sexual function, which featured a responsive form of desire in women's sexual response. Bancroft developed a new theoretical model, the Dual Control Model, which postulates sexual response and arousal is ultimately determined by the balance between the sexual activation or excitation system and the sexual inhibition system. The Sexual Tipping Point is a model created by Perelman, suggesting that a sexual response is determined by a balance between excitatory or inhibitory factors that may be psychological, organic, psychosocial, or cultural. A comprehensive understanding of sexual response and function is of paramount importance for the psychiatrist to study sex, offer counseling to the patient on sex, and practice sex therapy. In this literature, models of sexual response would be reviewed to understand the knowledge of the sexual functioning in humans.

  • The present study attempts to provide the practical methodology to determine the spatial boundary of trade area, not depending on conventional circle-based regional analysis, but adopting dimension-diverging conception based on GIS and road connectivity by exemplifying a large-scale discount store with an outlook to enhance accuracy and reliability in trade area analyzing. Unlike the preliminary researches frequently relying on circular form of interpretation which were not likely to exclude obstacles blocking the accessibility to trade areas, the method suggested by the study is to suggest an alternative way for demarcating the trade areas more practically with better access by excluding in-between obstacles. Finally, we show verification of proposed cost models and performance by join strategy.

  • The primary purpose of this study was to investigate high school students' conceptual understanding of density for solids and liquids in pure and mixed substances who had preceded formal school science instruction on density and related topics. A concept assessment on density was developed and administered by demonstrative experiments accompanied by a written assessment test method to 120 general high school students in a metropolitan city. The scientific conceptions and alternative conceptions from students' responses were identified and the percentages of them were calculated. Then, their alternative conceptions and implicit theories on density were analyzed. About half of the students couldn't differentiate weight-volume-density and regarded density as an innate property of matter. Furthermore, the greater the number of variables involved in an experimental condition of the question, the more complicated and undifferentiated students' density concepts were. Students employed more improper variables such as particle size, intermolecular distance, surface tension, polarity of the solvent, etc. in explaining counter-intuitive observations. The implications for school science instruction were discussed.

  • This study provides a comprehensive survey of Post Keynesian economics. The global financial crisis 2008-2009 has triggered an important debate concerning economic theory, policy and methodology. The most important thing that this economic crisis has done for economics is that it revealed mainstream economics was wrong. Mainstream economics has been unable to offer clear answers for the crisis. The economic crisis, at the same time, brought about a crisis in the field of economics. This study suggests that economics needs to be altered into a new form that can explain the real world economy. In this paper, it is argued that Post Keynesian economics can be understood as the alternative economics. The paper begins with the vision and the origins of several Post Keynesian ideas, leading to an examination of certain features of the various groups, including their methodology and their approaches to uncertainty, their pricing theories and their growth theories. The focus, however, is on the stage reflected in Post Keynesian economics which is concerned with the conception of Lakatos's 'Scientific Research Programmes'. It is recognized that more research is necessary in order to complete the post keynesian economics as a standard science or as a progressive Scientific Research Programmes in economics.

  • In the Western Philosophy that was centered on reason, sense has been belittled as a low level of conception under reason. However, the 21st century modern visual environment pushes away the epistemology centered on reason and puts 'sensuality' and 'sense' on its place. Especially, public films are one of the fields that rapidly reflect such changes and lead the changes. However, unfortunately, it is difficult to find such efforts that reflect the artistic and aesthetic significance of sense from the public films. It is because that sense is considered superficial and somewhat not real, while recognizing sense as the low level of conception under reason over the long history. Given the fact, this study reviews the by Gilles Deleuze, a modern philosopher who gives a new value on sense, and it would be meaningful to analyze the works of Chris Cunningham who makes films with the concept of Gilles Deleuze. After we analyzed three music videos of Aphex Twin directed by Chris Cunningham, we can ascertain that the films are based on body without Oranges, hysteric, and diagram that are suggested from by Gilles Deleuze. Analyzing recently released films centered on 'sense' in a superficial manner that includes production method or picture composition, including the films of Chris Cunningham, falls into the error of overlooking the director's aesthetics. Understanding the modern logic of sense that is newly developing, studying its substance, and analyzing the films will make a sacrifice of suggesting a new alternative.
