Objectives: The maintenance of the healthy periodontal ligament cells of the root surface of donor tooth and intimate surface contact between the donor tooth and the recipient bone are the key factors for successful tooth transplantation. In order to achieve these purposes, a duplicated donor tooth model can be utilized to reduce the extra-oral time using the computer-aided rapid prototyping (CARP) technique. Materials and Methods: Briefly, a three-dimensional digital imaging and communication in medicine (DICOM) image with the real dimensions of the donor tooth was obtained from a computed tomography (CT), and a life-sized resin tooth model was fabricated. Dimensional errors between real tooth, 3D CT image model and CARP model were calculated. And extra-oral time was recorded during the autotransplantation of the teeth. Results: The average extra-oral time was 7 min 25 sec with the range of immediate to 25 min in cases which extra-oral root canal treatments were not performed while it was 9 min 15 sec when extra-oral root canal treatments were performed. The average radiographic distance between the root surface and the alveolar bone was 1.17 mm and 1.35 mm at mesial cervix and apex; they were 0.98 mm and 1.26 mm at the distal cervix and apex. When the dimensional errors between real tooth, 3D CT image model and CARP model were measured in cadavers, the average of absolute error was 0.291 mm between real teeth and CARP model. Conclusions: These data indicate that CARP may be of value in minimizing the extra-oral time and the gap between the donor tooth and the recipient alveolar bone in tooth transplantation.

Recent development of teachable agent provides learners with active roles as knowledge constructors and focuses on the individualization. The aim of this adaptive agent is not only to maximize the learner's cognitive functions but also to enhance the interests and motivation to learn. In order to establish the relationships among user characteristics and response patterns and to extract the algorithm among variables, we measured the individual characteristics and analyzed logs of the teachable agent named KORI (KORea university Intelligent agent) through the student modeling. A correlation analysis was conducted to identify the relationships among individual characteristics, user responses, and learning outcomes. Among hundreds of possible relationships between numerous variables in three dimensions, nine key user responses were extracted, which were highly correlated with either individual characteristics and learning outcomes. The results suggest that certain type of learner responses or the combination of the responses would be useful indices to predict the learners' individual characteristics and ongoing learning outcome. This study proposed a new type of dynamic assessment for individual differences and ongoing cognitive/motivational learning outcomes through the computation of responses without measuring them directly. The construction of individualized student model based on the ongoing response pattern of the user that are highly correlated with the individual differences and learning outcome may be the useful methodology to understand the learner's dynamic change during learning.

A significant gap can exist between what customers expect in foodservice and what service providers deliver to customers. Reducing the gap and enhancing service quality plays a key role in increasing customer satisfaction and repurchase intentions. The purpose of this study was to investigate the personal and operational characteristics that affect the customer perceptions of service quality, to analyze the overall satisfaction and repurchase intention of customers, and to study the service quality gap between customer and foodservice provides. 427 customers and 278 foodservice providers in 82 fast food and family restaurants were surveyed. T-test, ANOVA, Correlation Analysis, and Multiple Regression were used for statistical analysis, The results of this study were as follows: 1) Among the personal characteristics of customers, sex affected the preception of 'General Management' and 'Reputation', and the expense per person showed a correlation with service quality. 2) Among the operational characteristics, the type of restaurant, months since opening, and the number of seats had a significant impact on service quality, while the seat turnover rate showed a negative correlation with service quality. 3) Among the human resource characteristics, the proportion of part-time employees had a negative correlation with service quality, and in general, the training program for full-time employees led to a higher degree of customer perception of service quality. 4) Six dimensions of service quality accounted for 38.39% of customer satisfaction in Multiple Regression. 5) The overall satisfaction of customers willing to repurchase was significantly higher than that of the non-repurchase customers. 6) The operational characteristics explained over 35% for the service quality gap among the customers and the service providers in Multiple Regression.

Background: The aim of this study is to analyze determinants of welfare attitudes toward healthcare services in South Korea, using three main theories: self-interest (positive welfare attitudes if the policy fulfills people's personal interests), symbolic attitudes (positive welfare attitudes if the person is politically progressive or egalitarian), and sociotropic perception (positive welfare attitudes if the person experienced positive aggregated collective experiences of societal events and trends regarding the policy). Although the definition of the welfare attitude is rather ambiguous in literatures, in this investigation, we operationalize the concept as the 'willingness to pay higher taxes to improve the level of health care services for all people in Korea' which shows individuals' actional propensity. Methods: We used the health module from the International Social Survey Program 2011 for the analysis (N= 1,391). Five logistic regression models were built successively using two variables for each theory to measure key concepts of self-interest, symbolic attitudes, and sociotropic perceptions as independent variables. Results: The result showed self-interest and symbolic attitudes factors to be strong determinants of welfare attitudes towards healthcare services in South Korea, whereas sociotropic perception factors have inconsistent effects. Conclusion: For a more politically elaborated healthcare reform in South Korea and elsewhere, there needs to be further research on various dimensions and determinants of welfare attitudes to understand popular basis of welfare expansion, especially in the era of inequality.

As diverse online information services are introduced and the use of them are increasing, the importance of the quality control over the online information services is also increasing. Therefore, studies are being attempted to derive quality evaluation models for online information services, but these showed many limitations. In order to overcome the limitations of the previous studies and create more appropriate quality evaluation model, this study analyzed 408 data collected through the interviews with the users of Korea national online information services (NDSL, NTIS) using content analysis and the coding method of ground theory. Through the analysis, we identified the quality evaluation model (13 elements, 6 dimensions) of online information services and the description and insights of each elements. And the priorities of the most significant element(amount of information) and other key elements(such as the usefulness of the information, the diversity of the field, etc.) were figured out through the frequency analysis. Through these inductive methods based on the responses of users, the quality control model could be derived, which is different from the previous researches. This study is the first study which derived the quality evaluation model of online information service through the inductive way based on 408 interview responses from users. Therefore, the results of this study will be helpful to the post researchers who conduct studies on the quality of online information service, etc. Moreover, the results of this study are expected to provide references of frame for decision-making of working-level officials who have to manage the quality of online information services.

The purpose of this study is to analyze and compare dental hygine curriculum of three countries--Korea, U.S.A., and Japan--, focusing on the ways of organizing content. In this study, 30 curriculum documents of dental hygienist in U.S., Japan, and Korea were analyzed and discussed by a framework of analysis which was constructed referring to Tylerian curriculum model. Using this framework, three kinds of key components of curriculum document were compared according to specific elements of each component. More specifically, comparing those curriculum documents, we must consider the dimension of content organization. In this study, the problem of course organization was viewed on three dimensions: continuity, sequence, and integration of curriculum content. Based on the results of this study, the conclusions are as follows. 1. Courses of dental hygienist education should be organized so that the curriculum foster the cumulative and continuous learning. It will be accomplished by considering the essential procedures or sequence of dental hygiene activities. 2. When organizing curriculum elements, we should consider the continuity dimension of learning content. Continuity deals with the vertical manipulation or repetition of curriculum components. In other words, it accounts for the reappearance in the curriculum of certain major ideas or skills. Therefore, courses should be based on the level of the dental hygienist activities in order to ensure a continuity of learning experiences. 3. Dental hygienist curriculum must be organized in a way to integrate the logic of dental hygiene as a discipline with the process of dental hygiene performance. Integration refers to the linking of all types of knowledge and experiences contained within the curriculum design. It emphasizes horizontal relations among various content topics and themes involving all domains of knowledge recognized. Thus, courses of dental hygiene curriculum should be integrated to allow college students to obtain a unified view of knowledge and an in-depth meaning of the dental hygiene as a profession.

The objective of this study is to understand bodily extension and identity in contemporary fashion art through the analysis of 'the fashion acting on the body' among the fashion theory excluding body and the conspicuous works on the opening and covering images as a fashion art as a body-space'. This study also investigated identity problems where there are poles apart in opening and closure their bodies and body-space in which its clothing types were distorted by being de-bodilization out of the traditional and ideological expression method in contemporary fashion art from a opening and closure point of view. Image of opening and closure among body-space in fashion art can be classified into opposing structure of opening and closure. Destroying the boundary between bodily opening and closure for a primary function of clothing and dismantling the role and boundary between body and clothing, opening body-space in appearance as a reemergence of body image or the border between inner and outer are being ambiguous because of transparent material. Being representative work of this study opening body-space was expressed as an opening space image using transparency. On the contrary, closure body-space was isolated from external environment and confined in the certain space, which could limit or restraint body- action. Excluding boundary of body and clothing on the whole or in part, boundary of work becomes body-space. However, these were appeared to be a work inducing unlimited curiosity and meaning from the audience. The interpretation of artistic and body-space in fashion art are indicating the role and function of the fashion art exceeding the suggestible dimensions in the every day life of fashion. The body-space of fashion art showing similar aspect of body art today could be understood that it is substituted into an metaphorical, critical space by seeing it as a symbol system connected with social space. Therefore, contemporary fashion art should be interpreted as an equivocal space looking at the body-space with open mind.
