This study compared the accuracy and reliability of definitive casts fabricated from a digital impression and conventional impression technique. A master model with the prepared upper full-arch tooth was used. Samples of ten plaster models and ten polyurethane models were duplicated using a selected standard master model. Six linear measurements were recorded between the landmarks, directly on each of the stone models and the polyurethane models on two occasions by a double examiner. The Wilcoxon signed-rank test, interclass correlation coefficient (ICC), measurement error (MSE), and limit of agreement (LoA) were used for statistical analysis. The ICC ranged from 0.76 to 0.99 when comparing the stone models and polyurethane models. The mean difference between the stone models and polyurethane models ranged from 0.09mm to 0.20mm, suggesting that stone models might be slightly larger than polyurethane models. Based on this study, the accuracy of the polyurethane models in evaluating the performance of an oral scanner and subtractive technology was acceptable. Further studies will be needed on patient subjects under clinical conditions that may involve missing or malpositioned teeth and fixed dental prostheses because this study was limited to use a standard master model and duplicated sample models in a laboratory setting.

As digital communication gains prominence, there is an increasing trend in uncivil behaviors like rude or hateful comments and the empathetic actions towards them, highlighting the need for social efforts to address these issues. As part of these endeavors, we investigated how avatar feedback in a virtual news portal affects users' empathy towards uncivil comments. We defined both posting and empathizing with uncivil comments as antisocial actions. To this end, we posted socially controversial news in a virtual space and provided feedback in two forms when participants selected uncivil comments: text-only feedback and feedback accompanied by an avatar. We then assessed the impact of this feedback on behavioral conformity, guilt, and self-image concern through surveys. Our results showed that avatar-provided feedback significantly influenced participants' social responses more than text-based feedback. Interaction with avatars notably increased participants' behavioral conformity, guilt, and self-image concern. We concluded that avatar-based interactions can positively influence users' social behaviors and attitudes, suggesting their potential in fostering a more civil and responsible digital communication culture.

The scientific verification of the physiological and psychological effects that result from interaction with green plants would not only provide objective knowledge on the psychological effect of green but would also establish useful grounds for the creation of green spaces that consider human emotions. The present study measured the cerebral activity(cerebral blood flow) and the autonomic nervous system activity (blood pressure, pulse rate, amylase) of fifteen Korean male subjects as they inhaled the natural scent diffused by pine needles. Impression and mood state evaluations of the reactions to the pine scent were carried out using the SD method and POMS. Cerebral activity was observed to be significantly activated in the feeling, judgment, and motor areas of the frontal lobe, as well as the memory area in the temporal lobe. Verbal evaluations by the SD method and POMS indicated a pine scent left natural but stimulated and active impressions, provided vigor, and also reduced confusion. The autonomic nervous system activities, however, showed no significant differences. These findings verified scientifically that a pine scent vitalizes humans both physiologically and psychologically. These results could be useful as fundamental data for the design of green spaces that consider human emotional aspects.

Objectives : This study examined the characteristics and differences of PAI(Personality Assessment Inventory) profile between compensation-seeking(CS) and treatment-seeking(TS) patients with traumatic brain injury(TBI) and assessed the clinical meaning of the characteristics and differences of profiles between the two groups. Methods : 36 TBI patients who visited the Wonkwang University Hospital were selected. The patients were categorized as compensation-seeking TBI patients(n=22) and treatment-seeking TBI patients(n=14). The PAI scales and subscales were used to compare differences between two groups. t-verification for each variable and comparison analysis were performed. Results:In validity scales, CS group showed significantly higher NIM scores and lower PIM scores than TS groups. In full scales, CS group showed significantly higher SOM, ANX, ARD, DEP, and SCZ scores than TS group. In subscales, CS group showed significantly higher SOM-S, ANX-A, ARD-P, DEP(-C, A, P), (MAN-I), PAR-H, SCZ(-T, P), BOR(-A, N), and ANT-S scores than TS groups. In supplementary scales, CS group showed significantly higher SUI, NON and AGG-P, and lower RXR scores than TS group. Conclusions:There were significant differences in PAI scales with validity scales, some full and subscales according to compensation seeking status in TBI patients. The CS patients tended to exaggerate their symptoms on PAI, and showed higher scores representing somatic preoccupation and emotional distress. These results show the usefulness of PAI in reflecting the significant psychological differences between two groups.

Nowadays, as many robots are developed for desktop, users interact with the robots based on speech. However, due to technical limitations related to speech-based interaction, an alternative is needed. We designed this research to design a robot that interacts with the user by using unconditional reflection of biological signals. In order to apply bio-signals to robots more effectively, we evaluated the robots' overall service evaluation, perceived intelligence, appropriateness, trustworthy, and sociability according to the degree of the robot's embodiment level and the response speed of the robot. The result showed that in terms of intelligence and appropriateness, 3D robot with higher embodiment level was more positively evaluated than 2D robot with lower embodiment level. Also, the robot with faster response rate was evaluated more favorably in overall service evaluation, intelligence, appropriateness, trustworthy, and sociability than the robot with slower response rate. In addition, in service evaluation, trustworthy, and sociability, there were interaction effects according to the robot's embodiment level and the response speed.

This study aims to provide policy suggestions by examining the perception and attitude of Koreans toward the welfare rights. The study was done through a telephone survey conducted by an opinion research institute on 2,050 respondents in 16 cities and provinces. The results are as follows. First, a majority of Koreans responded that the primary responsibility for welfare rests with the government and perceived their welfare receipt rights in a positive way. Respondents also showed an assertive attitude toward exercising their rights by stating that they intend to file a demurrer or participate in civic activities. Second, in terms of duty performance, most respondents showed different positions concerning tax hike and insurance rate increase, although they showed a stronger opposition to an increase in insurance fee. In addition, 90% of the respondents were in favor of building welfare institutions in the residential area and an overwhelming proportion of the respondents indicated that they would take an active part in welfare development by regularly paying taxes and volunteering. Third, the respondents gave a very negative rating to Koreas welfare system and its overall level. That is, people thought that the level of Koreas welfare system is on a par with that in developing or underdeveloped countries, and that the welfare system benefits no one or only the rich. People generally felt that there was not one proper welfare institution. In conclusion, the study found that Koreans have keen awareness of their welfare rights and proactive attitude toward welfare development, whereas negative viewpoint toward tax and insurance fee increases. This may stem from peoples distrust of government welfare policies and the existing welfare system. This study suggests that welfare policy is an important factor in determining peoples political attitude. Therefore, government authorities must recognize people not as passive receivers of welfare benefit but as active policy partners, and establish policies that reflect peoples high welfare rights perception and willingness to take part in welfare development.

This study was done to evaluate the reliability of the digital color analysis system (ShadeScan, CYNOVAD, Montreal. Canada) for dentistry. Sixteen tooth models were made by injecting the A2 shade chemical cured resin for temporary crown into the impression acquired from 16 adults. Surfaces of the model teeth were polished with resin polishing cloth. The window of the ShadeScan handpiece was placed on the labial surface of tooth and tooth images were captured, and each tooth shade was analyzed with the ShadeScan software. Captured images were selected in groups, and compared one another. Two models were selected to evaluate repeatability of ShadeScan, and shade analysis was performed 10 times for each tooth. And, to ascertain the color difference of same shade code analyzed by ShadeScan, CIE $L^*a^*b^*$values of shade guide of Gradia Direct (GC, Tokyo, Japan) were measured on the white and black background using the Spectrolino (GretagMacbeth, USA), and Shade map of each shade guide was captured using the ShadeScan. There were no teeth that were analyzed as A2 shade and unique shade. And shade mapping analyses of the same tooth revealed similar shade and distribution except incisal third. Color difference (${\Delta}E^*$) among the Shade map which analyzed as same shade by ShadeScan were above 3. Within the limits of this study, digital color analysis instrument for dentistry has relatively high repeatability, but has controversial in accuracy.
