  • In these days, the design of a structure for reducing or eliminating noise and vibration is getting more important, as the social demands for reducing environmental pollution rise. In this paper, the basic concept and performance verification test results of the recently developed vertical vibration isolator are presented. The isolator attenuates vibration using the damping action from the friction plane made of PTFE and provides the restoring force from the polyurethane springs arranged in vertical and horizontal directions. The performance verification tests consist of a test for identifying performance change during load rate variation and a test for confirming the force-displacement relationship assumption in vibration force range.

  • Storytelling techniques have been using for utilizing in various fields such as education, marketing and so on. In creative content sector, especially, the amount of creating the a newly story content from existing oral tales which are short and quite hard to understand the context has been increased. However, there are some limitations for creating the ideas of the story according to the expansion of the stories while the approach for new adaptation of existing stories is quite challenging. In this paper, therefore, we described the preliminary steps of text analysis and object extraction method for story development which can be applied to the storytelling authoring supported software.

  • An edutainment is a composite which are joining with the serveral matter and the multiplicity of techqniues An Eduainment software use serveral audio and video media. The human have different preference to audio and video media. It is difficult to evaluate quality of an edutainment software than a general software. So, we need an evaluation factors to compare quality of edutainment software. We developed the evaluation factors for edutainment software. And the middle school students used the evaluation factors to evaluate the favorite edutainment softwares among them. We evaluate and analyze the results.

  • The 3D animation these days is confronted with a situation that should develop new contents fit for those circumstances of media in which new platforms such as smart phones, tablet PCs, and smart TVs, etc. are in a rapid change and establish media strategies. Attempts are made of developing methods to diversify content type coping with new smart media characteristics including smart phones, tablet PCs, and smart TVs, etc., with materials of the same story and character, and developing animation video contents based on new media technology. This study made avatas utilizing iClone, avata 3D production technology and investigated 3D animation production methods through costume editing and motion editing.

  • This study was conducted to investigate antioxidative and physiological activities of ethanol extracts concentration from Monascus-Fermented Chinese Yam (MFCY). The ethanol extracts from MFCY were measured to examine pigments, DPPH radical scavenging activity, reducing power and monacolin K contents. As a results show that Monascus sp. MK805, with Dioscorea japonica as the substrate can produce pigments (yellow, orange and red), DPPH radical scavenging activity, reducing power and monacolin K content at 29.6 (yellow), 15.1 (orange), 20.4 (red), 72.8%, 1.74(OD at 700nm), 480.6 mg/kg in EtOH extract, respectively. Therefore, fermented chinese yam (Dioscorea japonica) was estimated to be effective biological activity material.

  • The electricity consumption time series data of 'A' University from July 2016 to June 2017 is analyzed via nonparametric functional data clustering since the time series data can be regarded as realization of continuous functions with dependency structure. We use a Bouveyron and Jacques (Advances in Data Analysis and Classification, 5, 4, 281-300, 2011) method based on model-based functional clustering with an FEM algorithm that assumes a Gaussian distribution on functional principal components. Clusterwise analysis is provided with cluster mean functions, densities and cluster profiles.

  • In VANETs (Vehicular Ad hoc NETwork), conditional anonymity must be provided to protect privacy of vehicles while enabling authorities to identify misbehaving vehicles. To this end, previous systems provide a mechanism to revoke the anonymity of individual messages. In VANET, if we can trace the movement path of vehicles, it can be useful in determining the liability of vehicles in car accidents and crime investigations. Although route tracing can be provided using previous message revocation techniques, they violate privacy of other vehicles. In this paper, we provide a route tracing technique that protects privacy of vehicles that are not targeted. The proposed method can be employed independently of the authentication mechanism used and includes a mechanism to prevent authorities from abusing this new function.

  • This study conducted an online survey of university students based in Jeolla-do province from September 1 to 10, 2020 using Naver survey form to find out the perception and attitude of paramedic students about child abuse. A total of 293 students were studied, and the collected data was analyzed using SPSS WIN 20.0. The analysis of general characteristics, recognition of child abuse reporting obligations and activation plans, and awareness of child abuse education were calculated with frequency and percentage, and the degree of child abuse awareness was calculated by the average and standard deviation. Differences in perception of child abuse behavior based on the general characteristics of respondents were used T-test and ANOVA.

  • The meaning of hologram is widely used as a similar hologram. The use of holograms has been proposed in many cases. In this paper, we present an outline of similar holograms using up to 3 or 4 facets, and express the similar holograms using the results produced by 3D modeling of the university headquarters building at Wonkwang University. Through this, a virtual building seen by the human eye can be virtually shown in space through a hologram among various methods shown in a virtual space such as AR / VR / MR. Through this study, it is possible to try to construct a new digital contents utilization area by expressing various materials such as buildings or cultural property buildings through hologram.
