  • Introduction: Diffusion is process by which an innovation is communicated through certain channel overtime among the members of a social system(Rogers 1983). Bass(1969) suggested the Bass model describing diffusion process. The Bass model assumes potential adopters of innovation are influenced by mass-media and word-of-mouth from communication with previous adopters. Various expansions of the Bass model have been conducted. Some of them proposed a third factor affecting diffusion. Others proposed multinational diffusion model and it stressed interactive effect on diffusion among several countries. We add a spatial factor in the Bass model as a third communication factor. Because of situation where we can not control the interaction between markets, we need to consider that diffusion within certain market can be influenced by diffusion in contiguous market. The process that certain type of retail extends is a result that particular market can be described by the retail life cycle. Diffusion of retail has pattern following three phases of spatial diffusion: adoption of innovation happens in near the diffusion center first, spreads to the vicinity of the diffusing center and then adoption of innovation is completed in peripheral areas in saturation stage. So we expect spatial effect to be important to describe diffusion of domestic discount store. We define a spatial diffusion model using multinational diffusion model and apply it to the diffusion of discount store. Modeling: In this paper, we define a spatial diffusion model and apply it to the diffusion of discount store. To define a spatial diffusion model, we expand learning model(Kumar and Krishnan 2002) and separate diffusion process in diffusion center(market A) from diffusion process in the vicinity of the diffusing center(market B). The proposed spatial diffusion model is shown in equation (1a) and (1b). Equation (1a) is the diffusion process in diffusion center and equation (1b) is one in the vicinity of the diffusing center. $$\array{{S_{i,t}=(p_i+q_i{\frac{Y_{i,t-1}}{m_i}})(m_i-Y_{i,t-1})\;i{\in}\{1,{\cdots},I\}\;(1a)}\\{S_{j,t}=(p_j+q_j{\frac{Y_{j,t-1}}{m_i}}+{\sum\limits_{i=1}^I}{\gamma}_{ij}{\frac{Y_{i,t-1}}{m_i}})(m_j-Y_{j,t-1})\;i{\in}\{1,{\cdots},I\},\;j{\in}\{I+1,{\cdots},I+J\}\;(1b)}}$$ We rise two research questions. (1) The proposed spatial diffusion model is more effective than the Bass model to describe the diffusion of discount stores. (2) The more similar retail environment of diffusing center with that of the vicinity of the contiguous market is, the larger spatial effect of diffusing center on diffusion of the vicinity of the contiguous market is. To examine above two questions, we adopt the Bass model to estimate diffusion of discount store first. Next spatial diffusion model where spatial factor is added to the Bass model is used to estimate it. Finally by comparing Bass model with spatial diffusion model, we try to find out which model describes diffusion of discount store better. In addition, we investigate the relationship between similarity of retail environment(conceptual distance) and spatial factor impact with correlation analysis. Result and Implication: We suggest spatial diffusion model to describe diffusion of discount stores. To examine the proposed spatial diffusion model, 347 domestic discount stores are used and we divide nation into 5 districts, Seoul-Gyeongin(SG), Busan-Gyeongnam(BG), Daegu-Gyeongbuk(DG), Gwan- gju-Jeonla(GJ), Daejeon-Chungcheong(DC), and the result is shown

    . In a result of the Bass model(I), the estimates of innovation coefficient(p) and imitation coefficient(q) are 0.017 and 0.323 respectively. While the estimate of market potential is 384. A result of the Bass model(II) for each district shows the estimates of innovation coefficient(p) in SG is 0.019 and the lowest among 5 areas. This is because SG is the diffusion center. The estimates of imitation coefficient(q) in BG is 0.353 and the highest. The imitation coefficient in the vicinity of the diffusing center such as BG is higher than that in the diffusing center because much information flows through various paths more as diffusion is progressing. A result of the Bass model(II) shows the estimates of innovation coefficient(p) in SG is 0.019 and the lowest among 5 areas. This is because SG is the diffusion center. The estimates of imitation coefficient(q) in BG is 0.353 and the highest. The imitation coefficient in the vicinity of the diffusing center such as BG is higher than that in the diffusing center because much information flows through various paths more as diffusion is progressing. In a result of spatial diffusion model(IV), we can notice the changes between coefficients of the bass model and those of the spatial diffusion model. Except for GJ, the estimates of innovation and imitation coefficients in Model IV are lower than those in Model II. The changes of innovation and imitation coefficients are reflected to spatial coefficient(${\gamma}$). From spatial coefficient(${\gamma}$) we can infer that when the diffusion in the vicinity of the diffusing center occurs, the diffusion is influenced by one in the diffusing center. The difference between the Bass model(II) and the spatial diffusion model(IV) is statistically significant with the ${\chi}^2$-distributed likelihood ratio statistic is 16.598(p=0.0023). Which implies that the spatial diffusion model is more effective than the Bass model to describe diffusion of discount stores. So the research question (1) is supported. In addition, we found that there are statistically significant relationship between similarity of retail environment and spatial effect by using correlation analysis. So the research question (2) is also supported.

    • This study was to analyse the meanings of the appropriation inherited in the modern costumes from the latter of the 20th century to the present. According to the dictionary, the meanings of a word. "appropriation" is to steal something, used in order to avoid saying this directly. The sorts of the appropriation represented in the works of Art was as follow : First. the reconstruction by the imitation of the works of a great master or partly induction of the works of a great master Second, the introduction by the history, modern art, the image of popular culture Third, the imitation by the works of photograph, etc The appropriation in the modern costumes could be distinguished as two facts : First, the appropriation of the image of popular culture, 1) the way by the induction of popular factors of the extremely routine, commonplace character 2) the way by the citation of critical sentence of society, complaint message of the situation of times. Second, the reinterpretation of the past works : 1) the way by the reinterpretation of a great artist′s works, or popular works. In accordance with its change of a standard of value of the beauty, the products of modern culture, called the artificial second image, that is, popular factor, ready made factor, a signboard, a trademark etc, was appropriated in modern costumes and was reinterpreted by the works of fashion designer′s empathy. We can say that the modern costumes is not only the products of creative, original action of fashion designers but also the mirror of times, having relationship with society.

    • Globalization and multi-culturalizm have put light on the importance of cultural identity. To find or establish cultural identity designers have made their effort in their practice. Understanding possible expressional method for cultural identity in this context koreanity, can be a basis to promote such activities. The propose of this study is to investigate expressional method of koreanity in interior design cases appeared which were introduced in major domestic periodical publications since 1995. 43 cases were analyzed by using the analysis frame of 4 expressional method , such as an indicative imitation method, a partial invoked method, a partial transformation method and a conceptual reception method. As result 47% of total cases were used the partial transformation method. 16% by the indicative imitation method, 7% by the partial invoked method and 30% by the conceptual reception method. This result indicated designers have had more active attitude in expressing koreanity with interpretation of traditional concept in a contemporary way, rather than simply introducing and immitating traditional object. Design examples were organized and explained according to expressional method types.

    • American trendy casual style can be characterized as fitted to body and rendering sexy and fashionable images and now very popular in Korea. This paper aims to identify how American trendy casual styles have been introduced and diffused among Korean young people and also compare the similarities and differences between American and Korean styles. American trendy casual style was introduced and diffused through 4 channels: people who have living experiences in America, media exposure by American films, TV dramas and fashion magazines, on-line network using internet cafe, club and blog, use of on-line shopping mall speciallized for purchasing American apparel brands. Some of American celebrities became fashion ikons and played critical roles in diffusing American trendy styles. Photos of those American celebrities and street fashion of Korean young women were collected through internet search from Sep. 2006 to Aug. 2007. 6 styles including leggings, mini skirt, short dress, skim jeans, pants with long boots, big bag and long necklace were selected as representing American trendy casual styles. Silhouettes and overall styling were very similar in all 6 items. But Differences were found in terms of rotor, amount of details, item coordination, matching shoes and overall images.

    • Authoring tools for sketching the motion of characters to be animated have been studied. However the natural interface for sound editing has not been sufficiently studied. In this paper, I present a novel method that sound sample is selected by speaking sound-imitation words(onomatopoeia). Experiment with the method based on statistical models, which is generally used for pattern recognition, showed up to 97% in the accuracy of recognition. In addition, to address the difficulty of data collection for newly enrolled sound samples, the GLR Test based on only one sample of each sound-imitation word showed almost the same accuracy as the previous method.

    • The imitation processed cheese (IPC), formulated with delactosed non fat dry milk (DENFDM) only, showed the smallest melting area. Calcium caseinate sample showed the largest spread. Satistically protein source as a major ingredient for the IPC yielded significantly different melting areas. In a similar fashion, initial melting temperature was markedly and significantly influenced by protein source. In effect of addition of DENFDM on microstructure of IPC analog revealed that as the fraction of DENFDM was decreased, the network was much more uniform and the fat globules were also better dispersed compared to DENFDM cheese analog. Therefore the results of this study help predict that melting and microstructural characteristics are largely but not solely dependent on the protein source. The DENFDM has a potential beneficial effect as a partial replacement of caseinate in the formation of IPC to characteristic close to processed cheese.

    • High-speed telecommunication systems are influenced by electromagnetic environments because they need a wide bandwidth to transmit signals. Immunity tests of telecommunication equipment are effective for improving its immunity to electromagnetic environments. However, immunity tests are expensive to carry out because there are several different tests. The correlation among the tests should therefore be examined in order to reduce the kinds of tests that are necessary. This paper investigates the correlation between the electrical fast transient/burst (EFTB) test and the radio frequency (RF) conductive immunity test. Imitation equipment was constructed with a balun, and a baseband signal was transmitted from the associated equipment to the imitation equipment. Then, disturbances were applied to the equipment, and the telecommunication quality was evaluated by using the bit error rate (BER). The results from the EFTB test indicated that the BER was less than $6{\times}10^{-5}$ and the value was independent of the peak value. The results from the RF conductive immunity test indicated that the BER was affected by the longitudinal conversion loss (LCL).

    • Purpose: This study examined the efficacy of parent training interventions to facilitate social reciprocity and language development in children with autism. Methods: The social interaction behaviors of mothers and children over time were compared using single subject design experimentation methodology. five children who were diagnosed with autism and their mothers participated in the study. The participants were recruited from U city, Korea. The mothers were trained using training videotapes and demonstrations on how to facilitate social interaction with their children as well as promoting language development. following the training, data were collected three times per week by video taping mother-child interaction in their homes. Results: Four of the five mothers demonstrated increases in the use of imitation with animation and expectant waiting after the intervention compared to the baseline sessions; the children demonstrated noticeable increases in the use of initiation of interaction, vocalizations, and verbal production after their mothers received the training intervention. Conclusion : Results of this study demonstrate the efficacy of mother training to improve social interactions of children with autism. Additional important information can be gained by replicating this study with more participants and comparing intervention and control groups. Clearly, this intervention shows promise and has implications far clinical practice.

    • In order to ensure the reliability and specialty of weapon system test results, a policy of extending certified testing service institutions has been driven by applying accreditation system of the ones in defense industry. Bass and Logistic models are used to apply the policy effectively and forecast the diffusion pattern of certified testing service institutions. The parameters for diffusion forecast are estimated using the diffusion pattern of certified testing service institutions in non-defense industry, and these are applied to forecast the diffusion of certified ones in defense industry. Coefficients of innovation and imitation of Bass model are analyzed to derive the factors influencing the early adoption and diffusion patterns. The more increasing the coefficients, the earlier adoption occurred. Diffusion pattern due to coefficient of imitation, internal factor, has larger effect on sensitivity of diffusion pattern. This means that the self recognition of necessity is more effectively worked than the policy or regulations driven by government.
