Purpose: This study examines the degree of empowerment recognized by the 1st paramedics and the trend of their critical thinking, analyzes correlations between empowerment and critical thinking to reveal whether there is statistically significant difference between them and then is to provide basic materials necessary for research on empowerment and critical thinking. Method: This study distributes 105 structured self-report questionnaires to the 1st emergency medical technicians working at fire fighting police boxes, general hospitals, clinics and emergency medical information centers in G Metropolitan City and J province from April 29 to May 28, 2006, collects their responses directly and analyzes results with t-test, F-test(ANOVA) and Pearson's Correlation Coefficient. Result: 1. First, average score of empowerment of subjects was 4.68 out of 6 and according to scores by area, capacity 5.98 was highest, followed by significance 5.41, self- determination 4.44 and effectiveness 3.79. 2. degree of empowerment according to general characteristics of subjects showed statistically significant differences in final education(F=2.714, p= .049), level of salary (F=3.298, p= .014) and satisfaction of current job (F=5.399, p= .001). 3. average score of critical thinking of subjects was 3.28 out of 7 and according to areas, no bias 3.95 was highest, followed by maturity 3.68, structure 3.35, inquisitiveness 3.11, pursuit of truth 3.07, critical thinking and self-confidence 3.00, analyticity 2.98. 4. degree of critical thinking by general characteristics of subjects showed statistically significant differences in age(F=2.577, p= .041), final education (F=7.877, p= .000), current workplace (F=3.513, p= .018), level of salary(F=4.628, p= .002), satisfaction with current job(F=6.879, p= .000) and intention to transfer current job(t=15.21, p=.000). 5. as a result of correlations between empowerment and critical thinking of subjects, Pearson correlation coefficients between whole empowerment and critical thinking were r= .21, p=.013. Conclusion: It is considered that the 1st paramedic managers must seek how to keep and manage empowerment and development of education and training program which can enhance critical thinking is needed. Further, emergency educators must develop educational program based on the concept of empowerment to establish early awareness of a desirable organization culture and increase understanding of empowerment in the process of education.

The pursuit of freedom by the individual--desire to be liberated from all forms of restrictions-- is one of the defining character-istic of the modern society. As costume is, in part, a product of the spirit of the times, it was only natural that this desire for freedom would find its expression in modern costume as well. Among various forms of restrictions, differentiaton by sex has placed one of the most significant binding influences on individual behavior. From early times, the dichotomous division by sex was incorporated into the disign of costume, and the traditional differestriction of costume by sex imposed a significant restriction on the background,“the modern androhynous look”was born as a by-product of the sexual liberation movement in the second half of the 20th century, based on the concept of the individual as a complete human being rather than as a member exclusively of either the male or the female sex. This paper seeks to examine the androgynous look within a coherent theoretical frame-work, and explore new design possibilities by analyzing and understanding the visual characteristics of the androgynous look. In addition, this paper seeks to define the functional aspects of the androgynous look based on the premise that costume is an embodiment of the spirit of the times. As for research methodology, both theoretical and historical methods are employed. Through a theoretical examination of historical documents, the meaning of the androgynous look is explored from various angles, and order to examine its place in modern fashion, an-drogynous styles are categorized and system atically analyzed. The main findings of the paper can be summarized as follows : 1. Androgyny is a compound word consisting of“andro-”(meaning man) and“gyn-”(meaning woman). In modern times, this word has been associated with the socio-cultural aspect of gender rather than the physical or physiological aspect with the pshchological characteristics of the male and female sexes. Androgynous styles also appear in fashion and general arts such as drama, film, dance, and music. In fashion, the androgynous look, represented by the visual superimposition of “masculine”and “faminine”elements, has emerged as a major element of the 20th-century costume, and has gained broad acceptance among those free spirits wishing to be liberated from the conventional conceptions of male clothing, and the unisex look. 3. The androgynous look in modern fashion reflects the spirit of the 20th century society and culture, and performs various functions as follows : expression of fun, change in gender roles, expression of the inner consciousness, and pursuit of the ideal human type.

With the explosive growth of the Internet, Internet shopping malls have become recognized as one of the major purchasing channels for consumers, as well as one of the competitive distribution channels for companies that allow them to contact with customers without intermediaries. It has motivated information systems(IS) researchers to examine the factors influencing consumer behavior and the purchase decision process in the context of Internet shopping malls. Despite the extensive research that has been conducted on the purchase decision process of consumers in online shopping malls, the results have demonstrated a need for further understanding of consumer behavior due to the unique features of virtual space and the characteristics of online consumers. Previous studies from marketing and consumer behavior domains have suggested that the concept of involvement plays an important role in explaining consumers' purchase behavior. Despite the critical role of involvement and the explosive growth of e-commerce, little research has examined the role of involvement in the Internet shopping mall context. With this motivation, this study has two research objectives. First, it introduces and tests an theoretical model capable of better explaining consumers' intention to purchase in the Internet shopping mall context. The proposed model extends and integrates existing models on purchase intention by incorporating purchase experience, innovativeness, and perceived self-control as the consumer factors, along with perceived risk, information provision, and perceived price as the Internet shopping mall factors. Second, this study examines how involvement differences may affect consumers' intention to purchase. For this purpose, two factors from involvement theory, involvement type and involvement level, are introduced into the research model as moderating variables. In order to test the proposed model, the overall approach employed was a field study using the structural equation model. We developed our data collection instrument by adopting existing validated questions wherever possible. All question items were measured with a seven-point, Likert-type scale, with anchors ranging from 'strongly disagree' to 'strongly agree.' Two IS researchers reviewed the instrument and checked its face validity. We collected empirical data for this study over a period of two weeks from subjects who had purchase experiences through Internet shopping malls. A total of 473 complete and valid responses were obtained. We carried out data analysis using a two-step methodology with AMOS 4.0. The first step in the data analysis was to establish the convergent and discriminant validity of the constructs. In the second step, we examined the structural model based on the cleansed measurement model. The empirical results partly support the proposed model and identify the moderating effect of involvement differences. Theoretical and practical implications of the study are discussed, along with its limitations.

Ionizing radiation is enough energy to interact with matter to remove orbital electrons, neutrons, and protons in the atom. Ionizing radiation like this leads to oxidizing metabolism that alter molecular structure through direct and indirect interactions of radiation with the deoxyribonucleic acid in the nucleus and cytoplasmic organelles or via products of cytoplasm radiolysis. These ionization can result in tissue damage and disruption of cellular function at the molecular level. Consequently, ionizing radiation-induced modifications of ion channels and transporters have been reported. When the harmful effects exceed those of homeostatic biochemical processes, induced biological changes persist and may be propagated to progeny cells. Also, Reactive oxygen species formed on the effect of ionizing radiation can get across into neighboring cells through the cell junctions that are responsible for intercellular chemical communication, and may there bring about changes characteristic to radiation damage. Depending on radiation dose, dose-rate and quality, these protective mechanisms may or may not be sufficient to cope with the stress. This paper briefly reviewed reports on ionization radiation effects on cellular level that support the concept of radiation biology. A better understanding of the biological effects of ionizing radiation will lead to better use of and better protection from radiation.

This study analyzes the process of establishing BSC based strategic performance evaluation system of KOMSCO. This case could be a reference to other public institutes for BSC introduction and efficient BSC usage. Internal control system of KOMSCO has been improved by EVA system in 1999, BSC introduction and Job analysis in 2001 through 2002, and BSC performance evaluation system in 2004. KOMSCO tries to reflect BSC concept by inducing employees to cooperate selection process of CSF and KPI and by considering the organizational characteristics of KOMSCO in constructing it's performance indices. It is suggested that these processes are very important and should be followed by other institutes in their BSC introduction. By applying BSC, KOMSCO provides improvement in employees' understanding of strategy, performance management, and performance evaluation. KOMSCO' information system based on ERP and efficiently connected to EIS, KMS, and BSC seems to play an important role of BSC application. BSC system of KOMSCO is now in the early stage of application and needs to be evaluated by the efficiency of usage in terms of overall performance evaluation system, deduction system of evaluation point for excess accomplishment over target, and connection to budget system.

On the subjects of elementary 3rd grade three child prodigies who had learned the four fundamental arithmetic operations and primary concepts of fraction, this study conducted a qualitative case research to examine how they composed schema of addition and multiplication of fractions and transformed schema through recognition of precise concepts and linking of concepts with addition and multiplication of fractions as the contents. That is to say, this study investigates what schema and transformed schema child prodigies form through composition of primary mathematic concepts to succeed in relational understanding of addition and multiplication of fractions, how they use their own formed schema and transformed schema for themselves to approach solutions to problems with addition and multiplication of fractions, and how the subjects' concept formation and schema in their problem solving competence proceed to carry out transformations. As a result, we can tell that precise recognition of primary concepts, schema, and transformed schema work as crucial factors when addition of fractions is associated with multiplication of fractions, and then that the schema and transformed schema that result from the connection among primary mathematic concepts and the precise recognition of the primary concepts play more important roles than any other factors in creative problem solving with respect to addition and multiplication of fractions.

Living spaces are the results of social environment and also the reflection of the viewpoints by their residents toward human culture and society. Therefore, in studying living spaces, the true essence of the spaces could be easily distorted when cultural and symbolic motives and values are disregarded and only their apparent characteristics are looked into. Hence, it's necessary to simultaneously understand both physical dwelling spaces from architecture's view points and social ideas, simultaneously, of people who form and interact with the spaces. Hence, this paper tries to study housing religion which is one of shamanistic religions which, in turn, have been the fundamental element of ancient religions and came into existence on the basis of dwelling spaces. This study presumes that house religion may have been permeated with its creators' ideas about living and those ideas could be one of those factors which plays a role in organizing of dwelling spaces. As such, with these prior analyses, this thesis attempts to understand the meaning of various dwelling spaces via the characteristics and functionalities of various house spirits which are mentioned in a local house religion and also will find out spatial harmony of Korean traditional living spaces by way of corelations among living spaces, people, and personalized house spirits. Almost all traditional Korean houses have assigned a house spirit to their individual dwelling space. This means a traditional house was considered as a scared space in a secular world called human society and the space was actually intended to protect sacredness of dwelling places from earthliness outside. So when the hierarchy of house spirits in housing religion is projected to a Korean traditional house, it can be shown that a dwelling house as a building was personified to a respectable human status. In other words, it can be concluded that each space was synonymous with a dwelling place for each house spirit and was considered a sacred godly place. In a nutshell, not only each space in a Korean traditional house was a physical and functional space, but also it formed a scared spatial place along with the concept of house spirits intending to ward off disasters and enjoy a comfortable life through those religious symbols and meanings. Housing shamanistic religion which has long been existing with residents and their lives is seeped with the viewpoints of the residents toward life, and hence understanding the meanings and organization of Korean traditional housing can reveal commonly practiced principles of spatial organization of the traditional houses. Therefore an analysis of Korean traditional housing on the basis of humanistic social ideas will help learn Korea's traditional houses which need to be understood in various methods.

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 examined the influences of cognitive conflict and anxiety induced by a discrepant event and an alternative hypothesis, attention, and effort on conceptual change. Two hundred three students having misconceptions about density were selected from 462 seventh graders based on the results of a preconception test. Tests of cognitive responses and anxiety to a discrepant event were administered before and after presenting an alternative hypothesis. Computer-assisted instruction (CAI) was then provided to students as a conceptual change intervention. Tests assessing attention and effort allocated to the CAI, and conceptual understanding were administered as posttests. Cognitive conflict induced by a discrepant event was found to increase after presenting an alternative hypothesis. Pre-cognitive conflict induced by only a discrepant event exerted a direct effect on post-cognitive conflict induced by a discrepant event and an alternative hypothesis. Post-cognitive conflict had a direct effect on conceptual change. Pre-anxiety decreased after presenting an alternative hypothesis. Pre-anxiety influenced post-anxiety, and this influenced on conceptual change via effort negatively. Attention had a direct effect as well as an indirect effect on conceptual change via effort. These results suggest that the strategy presenting both a discrepant event and an alternative hypothesis to students in concept learning could facilitate conceptual change by inducing more cognitive conflict or active participation of students through the decrease of anxiety than that presenting a discrepant event only.

Electronic displays have developed as instruments that function as windows of information to satisfy the bidirectional needs of electronic device manufacturers and users. The cathode-ray tube (CRT) display once dominated the display industry. Now, the liquid crystal display (LCD) is dominant, and promising displays are competing to become the next-generation display. Displays reflect the characteristics of the information and communication technology (ICT) industries, such as technological changes, innovative features, and competitive dynamics, and have technologically evolved to dominate the industry and market through various ICT devices. This research utilizes a dominant design concept and examines the case of the flat-panel display industry to propose a comprehensive framework, which considers technological, organizational, and environmental characteristics, of the determinants influencing dominance in the technology-intensive ICT industry. The results show that a dominant design in the flat-panel display industry emerges from technological competition among several designs, based on technological characteristics and market acceptance, and dominates the industry and market by various environmental factors. Our results emphasize the difference between generic technologies and the speed of technological innovation and expand the understanding of the emergence of a dominant design. Furthermore, this paper suggests practical implications for establishing a competition strategy and strategic guidance for other ICT industries as well as the display industry.
