The essential oil obtained by steam distillation from medicinal plants of Cinnamomum cassia and Prunellae Herba. Analysis of essential oils were performed on GC/MS selective detector. Separations were performed fused silica capillary column. The carrier gas was ultra pure helium with a flow of 1 $m{\ell}/min$ and the splitless injector temperature was set as $280^{\circ}C$. The column temperature program was as follows: initial temperature of $70^{\circ}C$ for 4 min, and increased by $2^{\circ}C/min$ 70 to $100^{\circ}C$ (held 2 min), After that the temperature was varied from 100 to $200^{\circ}C$ at $5^{\circ}C/min$ (held 20 min), increase to $280^{\circ}C$ (held 5 min) at $10^{\circ}C/min$, in a total run time of 73 min. Ten volatile flavor components were identified from C. cassia and ten volatile flavor components were identified from Prunellae Herba. Strong inhibition of growth of Vibrio parahaemolyticus was obtained with all doses of C. cassia tested. Moreover, antimicrobial activity of C. cassia occurred in a dose dependant manner.

The driving environment of the vehicle has characteristics that the change of position, velocity and distance between vehicles is severe. The performance test of system must be carried out in the real road environments with consideration of the driving environment of vehicles to measure the performance correctly because the performance of vehicular communication systems is affected by the driving conditions of the vehicle. In this paper, we propose the test methods of V2V/V2I performance and V2V multi-hop transmission function and present the test results measured by the vehicular communication systems already developed. In the test result, we confirmed the fact that the distance of communication devices and the driving direction of vehicle are affecting the communication performance. We also confirmed the multi-hop transmission function using the driving vehicle in the limited area as the proposed test method.

In the rapid growth of cities, road has heavy traffic and many buildings are under constructions. These kinds of environments make more difficulty for a person who is visually handicapped to walk comfortable. To alleviate the problem, we introduce Android based Portable Navigation System to help walking for Visually Impaired Person. It follows, service center give instant real time monitoring to visually impaired person for their convenient by this system. Android based Portable Navigation System has GPS, Camera, Audio and WI-FI(wireless fidelity) available. It means that GPS location and Camera image information can be sent to service center by WI-FI network. To be specific, transmitted GPS location information enables service center to figure out the visually impaired person's whereabouts and mark the location on the map. By delivered Camera image information, service center monitors the visually impaired person's view. Also, they can offer live guidance to visually impaired person by equipped Audio with live talking. To sum up, Android based Portable Navigation System is a specialized navigation system that gives practical effect to realize more comfortable walking for visually impaired person.

There has been many studies to explore what is the best multimedia tools for English learning by internet, but the students are still thirsty for the lack of practical and effective learning method which may lead them to stimulate their motivations to learn English with technological new media. The purpose of this study is to design Flash Animation as a new approach to learn language acquisition for those students who are learning English as a second language. This second is to show the validity for the introduction of Flash Animation into the English class. The third is to describe the effectiveness of the application of multimedia tools used in English communication such as java script programming and power point presentation.

The purpose of this research is to scrutinize what are characteristics of client-identified significant events and interactional process in Gestalt therapy using the therapeutic media. The subjects of the study were 4 participants. To this purpose, a audio-taped session and a intensive interview were conducted to examine. The collected data for this study were analyzed by Comprehensive Process Analysis. The audio-taped session and interview data were first transcribed and then analyzed for client-identified significant events. A total of 74 pairs of conversations were analyzed to derive the interactional process within the significant event case. In conclusion, it was found that the interactional process of significant events in the Gestalt therapy contributed to the change of the client by interacting with the therapeutic media. 5 major themes of interaction with the therapeutic madia appeared. The 5 major themes are allowance, identification, recognition, acceptance and prospective. Finally, the significance and limitations of the study were clarified and suggested for further study.

The avoidance tendency of voice call in younger generation facilitates the growth of mobile O2O service that utilizes Messaging. This study adopted and elaborated original concepts of telephone apprehension to apply phone anxiety to O2O. We examined previous researches related to the ubiquity of service quality, communication ability and anxiety, and then conducted a survey to understand the consciousness of mobile O2O service users. The results show that users with high message intimacy and users with poor logicality are afraid of voice calls. The mobile O2O service is considered useful as a means to replace an unstable situation. In this study, we considered individual characteristics of acceptance factor of O2O mobile service technology, and it was a new attempt to expand telephone apprehension characteristic reflecting current situation. In addition, the different results of this research from prior studies that examined the relationships among apprehension, usefulness, and continuous use intentions might be helpful to expand and sophisticate the research area.

Currently, virtual reality contents using VR images are spotlighted since they can be easily created and utilized. But because VR images are in a state of lack of interaction, there are limitations in their applications and usability.In order to overcome this problem, we propose a new method in which 360 degree panorama image and game engine are utilized to develop a high resolution of interactive VR service in real time. In particular, since the background image, which is represented by a form of panorama image, is pre-generated through a heavy rendering computation, it can be used to provide a immersive VR service with a relatively small amount of computation in run time on a low performance device. In order to show the effectiveness of our proposed method, an interactive game of a virtual zoo environment was implemented and illustrated showing that it can improve user interaction and immersion experience in a pretty good way.

This study is designed with an intention to understand CSR story strategies that the corporates use, focusing on analyzing the method of composition of Hyundai Motor Company's CSR website stories. When analyzing based on interactivity, ease of use, newest, and informativity, interactive dialogue feature was mostly lacking. It is not the most up-to-date data and lacks the newest. However, as sharing information feature was presented, information spread quickly. When applying Greimas' Actantial Model into the 'CSR News' that conveys the news about corporate philanthropic activities, it turned out that the CSR strategies were authenticity, consistency and flexibility. When doing CSR storytelling, a corporate should not only use pre-existing executives and staff members but should use new icons including civic organizations and the youth if possible, and perform its role as a supporter. At the same time, a corporate must build strategical storytelling to the new values and engage in systematic corporate philanthropic activities that meets the need of the time period.
