  • This study investigated the effect of presenting modes of multiple analogies on middle school students' understanding of science concepts. A total of 122 7th-graders was randomly assigned to one of 4 groups. After reading one of 4 analogy-learning materials in different analogy presenting modes (the number of analogs, the number of mappings between analog and target, and the comparison of similarity between analogs). the students took a conception test. The results indicated that using analogs and mappings twice were not significant factors in recalling and applying science concepts. However, the comparison of similarity between analogs was found to be a significant factor in applying science concepts. Educational implications are discussed.

  • The purpose of this study was to explore the concepts of health among people with mobility disabilities in order to develop a new holistic model of health and to identify implications for social work practice. A qualitative study based on face-to-face interviews with people with mobility disabilities was conducted. Nine consumers and nine social workers with mobility disabilities participated in the study. Social constructionism, heuristic paradigm, empowerment paradigm, and strength perspectives were used to form conceptual foundations to guide the study. Study participants' holistic descriptions of the concept of health encompassed five domains: biological/physical, mental/emotional, financial, relationships with others, and spiritual. Participants described health as harmony among these five domains. Harmony indicates that all five domains contribute to the concept of health, and that each domain is related to the others. Participants also viewed disability and health as an interconnected whole, not separate concept. The conceptual model developed in this study expands on the existing concepts of health by considering multiple factors at the personal and environmental levels, as well as interactions among the factors and between the levels. The personal level has five domains: biological/physical, mental/emotional, spiritual, financial, and relationships with others. The environmental level has also five domains: relationship with others, financial, social programs, social attitudes toward peoplewith disabilities, and physical environment. All factors under the personal and environmental levels also affect each other. The holistic concept of health for people with disabilities is not solely a part of the person, but rather is a function of the interaction between the person and their environment. The study demonstrated that people with disabilities have strength and resiliency, and health is an attainable goal for them, particularly when environmental and cultural barriers are addressed. The focus of social work practice should be the removal of those barriers encountered by their consumers with disabilities, as well as, the enhancement of internal factors that facilitate well-being.

  • The ability to share knowledge internally is critical to a firm's capability to gain competitive advantage through the leveraging of a firm's competencies, which are often "imprisoned" and dispersed across it's multiple businesses. The purpose of this paper is to propose knowledge sharing related factors which focus on variables regarding the success of knowledge sharing. To attain this purpose, this paper is structured in four main sections. We examined various concepts of knowledge sharing in the past research. We then briefly discuss about trends of methodological approach from the review of the existing studies. We go on to identify the factors that facilitate or hinder knowledge sharing within the firm. Factors regarding knowledge sharing were identified, analyzed, and summarized. Those factors could be categorize into three dimensions (structural, relational, and knowledge characteristics). Finally, we suggested areas for future research. Implications for the study on knowledge sharing were provided.

  • This study investigated the self-concepts of Korean students based on Marsh and Shavelson's(1985) multidimensional hierarchical model. Reduced forms of the Self-Description Questionnaire(SDQ)-I and -II were administered to 308 5th and 6th grade students and 718 7th to 9th grade students. Results of 2 factor analyses indicated that sub-scales 9 and 11 were well established for SDQ-I and -II, respectively, partly confirming the multidimensionality of self-concept. The factors involving distinctions between academic and non-academic higher-order factors and between the academic/math and the academic/verbal factors were not so differentiated nor hierarchically arranged as proposed by the model. These differences may be attributed to the heavy influence of the academic self-concept on the other sub-factors. A Locality ${\times}$ Sex ${\times}$ Grade ANOVA showed main effects of locality favoring urban areas and of sex favoring boys.

  • The abilities for 21st learners have recently changed and learners' engagement is emphasized. In flipped classroom, students learn the prerequisite concepts of the lecture online in advance and perform various types of activities based on interaction and engagement. As students in flipped classroom construct knowledge actively, students' engagement is very important. Therefore, I conducted a research of flipped mathematics class to help teachers to better understand students' engagement in flipped mathematics class. The flipped mathematics class was conducted for about 3 weeks with 29 middle school students and one teacher. Video and audio recordings, completed student worksheets and interview data were collected and analyzed using the qualitative method. The results of this study showed that students' engagement is influenced by diverse factors. Engagement factors were categorized by teacher factors, community factors, material factors, tasks and strategy factors, classroom culture factors. Each factor facilitates or suppresses behavioral, emotional, cognitive, agentic engagements, and sometimes several factors are related. The results of this study increase understanding of engagement through the example of a case study on flipped mathematics class.

  • One of the problems of derivatie spectrophotometry, the decrease of signal-to-noise ratio by derivative operations, was solved by three concepts of digital filtering, ensemble averaging, least squares polynomial smoothing and Fourier smoothing. The suthors made several compouter programs written in APPLE SOFT BASIC language for the actual applications of the concepts of these digital filters on UV spectrophotometer system. As a result, ensemble averaging could not be used as a routine operation for the spectrophotometer used. The maximum S/N ratio enhancement factors achieved by least squares polynomial smoothing were 6.17 and 7.47 for the spectra of Gaussian and Lorentzian distribution models, and by Fourier smoothing 16.42 and 11.78 for the spectra of two models, respectively.

  • The purpose of this study is to present the cognition of speculative aesthetics in the architectural space. Architectural space as the subject of the aesthetical study has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is also true that academic approach to the architectural space as per the aesthetic recognition has not been done so satisfactorily. The transcendental subjectivity as the aesthetic cognitive viewpoint of the architectural space means speculative aesthetics and the understands the essential meaning of the function and composition The conclusions of this study are as follows : The formalistic cognitive concepts including organic functional space between the whole and the part and anti-cubic synchronous space are included in the architecture of the speculative cognition, and finally the contextual cognitive concepts including the restoring analogical space of the in-depth constituent factors and associated centripetal spaces.

  • Since 1960's, structural engineers have recognized that tile inherent random nature of loadings and materials as well as the imperfect structural analysis may be important factors in tile structural safety evaluation. Based on the successful developments of the reliability based structural analysis and design, the design criteria of tile standards are recently developed(or modified) in the light of the probabilistic concepts. To develop the probability-based design criteria for tile domestic buildings, the probabilistic characters of loadings acting on structures should be defined first. In this study, therefore, live load data on apartment buildings have collected and analyzed in a systematic manner, and their probabilistic characteristics have been studied. Based oil the results, the lifetime extreme values are computed and compared with current design loads. More rational design loads are suggested, which are more consistent in the probabilistic concepts.

  • Actually, Cyberpunk is a compound word joined by cybernetics, which was used in control theory, and punk, was symbolized as anti-culture. Today, however, the definition of the term has been extended by various fields, used in many meanings. Therefore, the purpose of this study was to apply the Cyberpunk concepts to understand today s fashion because understanding of the present fashion is a means to interpret our culture. For this purpose, the phenomenon of Cyberpunk in fashion was subdivided into three factors material, color, and style. The results of the study were as follows : First, the materials used were techno material, special print by computer for future feeling and geometrical pattern, optical pattern to improve visual effects. Second, the colors mainly used were silver, black and white, bright color, and off-color of computer animation to present future-oriented feeling. Third, the general styles used were fit and slim, simple and liner, dualistic style to express future s image. In conclusion, the phenomena of Cyberpunk in fashion were expressed in material, color and style of fashion. Cyberpunk fashion was evident in T-shirts, sweaters, jackets, or as items of ornamentation such as pins, pendants, belts, and earrings, etc.

  • The purpose of this study is to investigate the changes of architectural characteristics of the rural houses in Jeju area for the last half a century. 72 houses in eight villages, which have been spontaneously renovated or added, were chosen as the rersearch samples. The subjects were classified into three groups-traditional, modernized, and contemporary houses-mainly by their construction years. Based upon these classification, the factors of change and continuation in building layout and spatial composition of dwellings have been investigated. As the results, Jeju rural houses show the tendency of the various and rapid changes in overall shape and spatial composition, but the traditional concepts of composition in plan has been maintained. Especially, the open structure of three-folded houses and the utilization of traditional floor system have been maintained as major design concepts to compose a house.
