In this research, we investigated the university students' consciousness and preference for the jacquard fabrics and developed the evaluation scale of the sensibility of jacquard fabrics appied by Korean traditional motives. 23 jacquard fabrics were assessed subjectively by 466 consumers using the 7-point scale of 23 descriptors of texture sensibility and 50 descriptors image sensibility. The percentage of students who were interested in jacquard fabrics was similar as that of students who were uninterested. 75.3% of students were shown to think that it was necessary to apply Korean traditional motives to the jacquard fabrics. Through cluster analysis, the hierarchy of the image sensibility was examined. The tactile sensibility of jacquard fabrics were classified into 9 sub-clusters, image sensibility of them were classified into 14 sub-clusters. The dimensions evaluating the image sensibility of jacquard fabrics were developed using multi-dimensional scaling method. A 3-dimensions and 6-axes system were determined, which consisted of 'classic-modern', 'splendid-plain', 'abstract-realistic'. It was shown that preference of jacquard fabrics was increased, as image sensibility such as 'various', 'gorgeouse', 'beautiful', 'mild', 'dim', 'traditional', 'orderly', 'comfortable', 'dignified', 'abundant', 'fantastic', and 'vague' were increased and those such as 'intense', 'old', 'stuffy', 'exotic' and 'static' were decreased.

This study aimed to understand the importance of applying finishing materials into interior space, and to add meaning to the creation of functional space, associated interior finishing materials with brain science. To achieve this purpose, brainwave(EEG) experiment was conducted. The brainwave appearing when sensing the surface of interior finishing materials with hands was measured. The locations of the electrode were FP1, FP2, F3, F4, C3, C4, P3, P4, O1, O2, F7, F8, T3, T4, T5, T6, CZ, FZ, and PZ and in addition to these, AFZ was added. Eight(8) kinds of finishing materials: metallic material, film paper, lumbar, stone, glass, silk wallpaper, fabric, and paint were used to measure '${\alpha}$-wave against ${\beta}$ wave.' As a result, it was found that the most activated finishing material in term of relaxation was film paper, followed by metallic, glass, paint, fabric, stone, lumbar, and silk wallpaper. To explain in light of this, (1) '${\alpha}$-wave against ${\beta}$ wave' was the most activated at ch1-FP1 and ch2-FP2, and at ch17-AFZ and ch19-FZ, which indicated that metopic-prefrontal lobe showed the highest activation in relaxation. Film paper, among the finishing materials, showed the highest increase in relaxation. (2) In general, '${\alpha}$-wave against ${\beta}$ wave' relaxation was inhibited at ch13-T3 and ch14-T4, and at ch15-T5 and ch16-T6 and the arousal in the temporal lobe was prominent. Silk wallpaper, among the finishing materials, showed the highest arounsal effect. As a result of measuring the superficial touch on the silk wallpaper, which was regarded as the most rough material among the eight finishing materials, the arousal effect of ${\alpha}$-wave against ${\beta}$-wave, among the brainwave characteristics, was found to be the highest. (3) to judge from the scope of this experiment regarding the tactile sensation over the finishing materials, it is considered that the brainwave reaction sometimes appeared contrastive depending on whether the surface was smooth or rough and there also appeared a difference in relaxation and arousal reaction of the brainwave depending on whether the surface was hot or cold, but the sensation on the surface texture was often evaluated differently depending on who you were. For this reason, this study has some limitations.

This study suggests an alternative breast-prosthesis-making process for female breast cancer patients. From June 2018 to July 2018, we conducted a study using nine females between the ages 40-50 who never had breast cancer. We recorded the reported subjective sensations and objective physiological responses to different types of artificial breast materials: Trulife silicon breast prostheses (TS) and hand-made silk breast prostheses (HS). Considering the materials used in TS and HS individually, we studied the subjective sensation with regards to how each material functioned in a photo (VP), movement (VM) and the visual tactility (VT) sense. The results showed that comparing VP and VT led to more significant differences than those comparing VM and VT. In addition, there was a significant difference in terms of tactile sensation when comparing TS and HS with respect to subjective responses to texture. Subjects reported that HS felt more comfortable and gave a better cooling sensation. However, the measured objective physiological responses indicated that skin temperature was higher with HS than TS when touched. This research contributes to scholarship around alternative and new materials to build breast prostheses for women with breast cancer.

Increased emphasis on competency-based learning modules and widespread departure from traditional models of Halstedian apprenticeship have made surgical simulation an increasingly appealing component of medical education. Surgical simulators are available in numerous modalities, including virtual, synthetic, animal, and non-living models. The ideal surgical simulator would facilitate the acquisition and refinement of surgical skills prior to clinical application, by mimicking the size, color, texture, recoil, and environment of the operating room. Simulation training has proven helpful for advancing specific surgical skills and techniques, aiding in early and late resident learning curves. In this review, the current applications and potential benefits of incorporating simulation-based surgical training into residency curriculum are explored in depth, specifically in the context of plastic surgery. Despite the prevalence of simulation-based training models, there is a paucity of research on integration into resident programs. Current curriculums emphasize the ability to identify anatomical landmarks and procedural steps through virtual simulation. Although transfer of these skills to the operating room is promising, careful attention must be paid to mastery versus memorization. In the authors' opinions, curriculums should involve step-wise employment of diverse models in different stages of training to assess milestones. To date, the simulation of tactile experience that is reminiscent of real-time clinical scenarios remains challenging, and a sophisticated model has yet to be established.
