  • This paper focuses on a sociologic approach, the theory of planned behavior (Ajzen 1991) and a sociolinguistic field, the language shift (Fishman 1991, Crystal 2000). It describes the theoretical background of language shift and briefly mentions the history of Hungarian language and Romanian language contacts. After presenting language use of the Hungarian minority students and explaining the theory of planned behavior, it turns to apply the theory of planned behavior to the language shift from the view of bilingual speaker(s). This paper wants to propose the application of the theory of planned behavior in language shift and open new perspective in bilingual research.

  • Some model building codes stipulate that the design displacement of a building can be computed using the elastic static analysis results multiplied by the deflection amplification factor, $C_d$. This approach for estimating the design displacement is essential and appealing in structural engineering practice when nonlinear response history analysis (NRHA) is not required. Furthermore, building codes stipulate the consideration of accidental torsion effects using accidental eccentricity, whether the buildings are symmetric-plan, or asymmetric-plan. In some model building codes, the accidental eccentricity is further amplified by the torsional amplification factor $A_x$ in order to minimize the discrepancy between statically and dynamically estimated responses. Therefore, this warrants exploration of the reliability of statically estimated design displacements in accordance with the building code requirements. This study uses the discrepancy curves as a way of assessing the reliability of the design displacement estimates resulting from the factors $C_d$ and $A_x$. The discrepancy curves show the exceedance probabilities of the differences between the statically estimated design displacements and NRHA results. The discrepancy curves of 3-story, 9-story, and 20-story example buildings are investigated in this study. The example buildings are steel special moment frames with frequency ratios equal to 0.7, 1.0, 1.3, and 1.6, as well as existing eccentricity ratios ranging from 0% to 30%.

  • The Dynamic Gait Index (DGI) was developed and widely used as a clinical tool to assess balance performance during gait. The purpose of this study was to validate the Korean translated DGI using Rasch analysis. A total of 105 community-dwelling elderly was participated in this study (age range = 65~95 years; mean = 78.0 years). The translated DGI showed sound item psychometric properties, and the 8 items were arranged in order of difficulty for the total participants. The most difficult item was 'Steps' and the easiest item was 'Level surface'. Also, each of the original 4 rating scale categories satisfied the Linacre's essential criteria suggestions for optimal rating scale category effectiveness. Although, thirty eight person (36.2%) showed the maximal high score, but the most of them was no history of fall in the preceding year. For subjects who has falling history, all of the person's ability was arranged within the item's difficulty. The 8-item Korean translated DGI can be used to measure gain in elderly person with balance disorders without compromising important clinical measurement characteristics in Korea.

  • This paper examines A. G. Frank's views about 15th-19th Korea (Joseon Dynasty) in his Reorient. A. G. Frank recognized that Korea might have played a great role in the international relations of East Asia, but he did not write systematically about it and he did not treat Korea as an independent player in the history of East Asia. I think the greatest limitation to his re-interpretation of East Asia is in that he depends too much on China's and Japan's perspective. In order to overcome Frank's shortcomings regarding the history of Korea, first I examine what Frank recognized about the Joseon dynasty between 1400 and 1800. Next I compare Joseon's development to that of China and Japan between 1400 and 1800. Frank compared Europe and East Asia (mainly China and Japan) from three aspects of quantities (population, production, productivity, and trade), qualities (science and technology), and mechanism (economic and financial institutions). With this research we insist that Joseon should not be dismissed in 15th-19th East Asia. The reasons are as follows. First, Joseon between 1400 and 1800 had developed economically as much as China and Japan. Second, Joseon had played a great role in connecting China and Japan and had a positive influence on the development of Japan. So we need to reappraise Reorient's view about East Asia. Only when role of Joseon can be correctly estimated, the dynamics and diversity of East Asia can be properly understood.

  • The threads of this thesis are several theoretical issues of modern urban ideals. Modern architects and urban designers conceived their individual artifacts, which assumed to be laid out on the new settings totally different from the existing urban fabrics derived from inherently medieval ones. In the discussion of modern ideal society, the Industrial Revolution and the Enlightenment was a pivotal point. Innovations in technology and expanded living territories since the double revolution have been critical factors in the evolution of new ideas of urbanism. The tremendous success in science and technology led a way to the 'science-fiction' environment as a destined apocalyptic world. The dream, whether it was socialist or in any other believes, to a pastoral utopia beyond the capitalist society was represented through the ideal cities, which were modern versions of arcadia in the other approaches. Two sides of revolutionary ideas are presented as a futurist city and a garden city, which are on the separate notions but co-existed or overlapped in a single urban project such as in Le Corbusier urban schemes or even Tchumi's recent work, Parc de la Villette. Urban ideas in the twentieth century are based on urban naturalism, the notion of which was consistant from abbe Laugier to Le Corbusier, as well as machine aesthetics interpreted in terms of archeological research and modern technology.

  • The purpose of this study was to improve the understanding of housing experiences of the women in their 50's in Korean social-cultural context and to explore their housing trajectory. The grounded theory was adopted in this study to address the research questions. Data was collected through in-depth interviews with the seven women in their 50's. The major findings of this study are summarized as follows. First, the their housing experiences of childhood is characterized by emotional and affective memory, whose sub-categories are nature and large family. Second, the respondents are categorized into two types according to their tenure of their first house after marriage. the respondents who started the housing careers with rental housing tend to move more frequently than the one who procured homeownership at the early stage of life course. Third, the respondents are satisfied with their present housing, consider it as their final housing but most of them are ready to sell their present house and move to smaller or cheaper house when their children need to money to buy the house for marriage.

  • Steel railway bridge gets vibration from moving load ; additionally, this kind of moving load is going to be a sufficient reason, which causes fatigue damage to steel railway bridge. Fatigue damage and stress curve were raised by moving load depends on span length in steel railway bridge. In other words, stress curve appears index regarding every axial load in short span, but self weight lets stress curve's change decrease in proportion to increasing span length. Thereby, we have studied that how the steel railway bridge appear fatigue damage in proportion to span length of steel railway bridge. Dynamic strain was measured in 4 steel plate-girder railway bridge during the trains was passing, which is located on the line of Kyoung-chun railway. And time history response analysis has been done in order to ensure actual survey. The results of this study show the decreased of the fatigue damage in steel railway bridge according to length of span. This paper ends is bases research of fatigue design in steel railway bridges according to span length.
